Based on chinese utility model patent application No. 200920001510.5 "vehicle driving's vision auxiliary sign combination" one in the left side sign a right side sign B the left side is rectified the sign and is reached the right side is rectified the sign the place ahead is rectified sign and correction portion and all can be located the car or be located the car outside, consequently, the utility model discloses in the setting of supplementary chi and correction portion, be close windshield's car interior position, simultaneously, also be fit for very much providing the student who trains class to drive the car and use. The installation instructions and the use instructions of the teaching aid for each student are as follows, so that the teaching aid can be used as a basis for practice in class and application after closing up:

firstly, installation instruction:

as shown in fig. 1, the common elements of the present invention: a left mark A, a right mark B, a left auxiliary ruler C, a right auxiliary ruler J, a positioning sticker D, a chalk E, a red thin line E1 with 20 centimeters, a white thin line F and two iron rings G, G1. The term "in the driver's vision" as used herein refers to the natural sight lines and vision in all directions generated by the most familiar seat position and the most familiar standard head position in the normal driving posture of the driver with different heights and habits. Please follow the following steps to install:

1. the vehicle is parked in a parking place with no water on the road surface, and the lower part of the inner surface of the front windshield is wiped clean.

2. As shown in fig. 2, two iron rings G, G1 and a white thin wire F with both ends tied thereon are taken out, the vehicle is turned off and gets off to the left side of the front bumper of the vehicle, one iron ring G is placed on the road surface near the left front tire, the other iron ring G1 is placed on the road surface about 4.5 meters in front of the vehicle, the thin wire F is straightened out towards the front of the vehicle, and if the wind is strong, heavy objects such as coins or stones can be pressed on the iron ring G1. The point is that the white thin line F is approximately a section of extension of the left vehicle body ground projection line H2 when viewed from the rear of the vehicle. Then, a left line segment H which is roughly parallel to the left line segment H is drawn on the left ground (the outer side of the vehicle) of the white thin line F by the chalk E, so that the distance between the two parallel lines of F and H is 20 cm (namely, the length of the red line E1 tied on the chalk E is slightly larger than the width of the left side rear-view mirror H3 of the automobile which protrudes out of the vehicle body). For simplicity, the chalk line length of most vehicle models can be only from about 2.5 meters in front of the vehicle to about 3.5 meters in front of the vehicle (as shown by the length P on the right side in the figure).

3. Fig. 3 shows a view looking out from the inside of the vehicle to the front glass of the steering wheel. When the driver sits on the seat, the left auxiliary ruler C is taken out, the release paper with the back adhesive removed is removed, the transverse line at the top end of the left auxiliary ruler C is upwards positioned and transversely and lightly adhered (will be removed) at the left lower part of the front windshield in the vehicle, and the key point is that when the driver sits after the left auxiliary ruler C is repeatedly adjusted and adhered, the transverse line at the top end of the left auxiliary ruler C is approximately overlapped on the transverse line of the window of the front windshield to be in a horizontal state, and the transverse line at the top end of the auxiliary ruler C and the left line segment H marked by the chalk on the road surface can generate a visual intersection point. Thus, a groove K is formed between the upper half of the left auxiliary ruler C and the glass (depending on the type of car, the corresponding position of the "lowest part of the glass window" on the glass may be the lowest part A3 of the windshield, the upper edge of the wiper rod or the highest part A2 of the visible surface of the front hood in order to make the lower part of the left auxiliary ruler C not obstruct the view of the car after the auxiliary ruler C is attached.

4. As shown in the left half of FIG. 4, the left sign A is taken out (the tail end of the correction part is deviated to the right) so that the minimum point angle M of the triangular plate is upward, the back face is toward the front, and the back release paper A25 is placed in the groove K without being torn off, at this time, the bottom edge I of the triangular plate is horizontal and can be easily slid left and right to adjust the position. Then, the left-side sign A is adjusted in the left-right direction by sitting right, so that the sight line projection point of the sharp angle M point in the vision of the driver is aligned with and falls on the left line segment H on the road surface, and an intersection point X point is generated (if two projection points are generated in the sense of being in the ground, the position of the sign A is adjusted by taking the projection point close to the right side as the reference), and the position of the sharp angle M point is the position to be used, namely the sharp angle M point is projected on the road surface in the vision and is the X point.

5. Repeating the steps 2, 3 and 4, and finding out a position to be used on the right side of the windshield:

as shown in fig. 2, the lower vehicle moves two iron rings G, G1 and the thin wire F to the right of the front bumper, and similarly, one iron ring G is placed on the road surface near the right front tire, the other iron ring G1 is placed on the road surface at about 4.5 m in front of the vehicle, and the thin wire is straightened. The key point is that the white thin line F is approximately a section of extension line of the projection line of the right vehicle body to the ground when viewed from the rear of the vehicle. Then, a right line segment P which is approximately parallel to the right side of the thin line (the outer side of the vehicle) is drawn by the chalk E, and the distance between the two lines F and P is 20 cm. Similarly, for simplicity, the length of the scribe line may be only from about 2.5 meters in front of the vehicle to about 3.5 meters in front of the vehicle.

6. As shown in fig. 3, when the driver sits on the seat and takes out the right auxiliary ruler J and the release paper a25 with its back adhesive removed, and the horizontal line at the tip end is positioned upward and lightly stuck (will be removed) to the lower right side of the center of the front windshield in the vehicle, the important point is to repeatedly adjust and stick the front auxiliary ruler J to the lower right side of the center of the front windshield, and the horizontal line at the tip end is horizontally overlapped on the horizontal line of the "lowest side of the window" of the front windshield "in the driver's vision, and the horizontal line at the tip end and the right line segment P drawn by the chalk on the road surface can form a visual intersection. Thus, a groove Q is formed between the upper half of the right auxiliary ruler J and the glass (depending on the vehicle type, the corresponding position of the "lowest part of the window" on the glass may be the lowest part A3 of the glass or the upper edge position of the wiper rod or the uppermost position a2 of the front hood in order to make the lower the position of the right auxiliary ruler J, the farther the position is, the farther the driving sight is obstructed after the auxiliary ruler J is attached).

7. As shown in the right half of FIG. 4, the right sign B is taken out (the tail end of the correction part is deviated to the left) so that the minimum sharp angle N point of the triangular plate faces upward, the back face faces forward, and the back release paper A25 is placed in the groove Q without being torn off temporarily, at this time, the bottom edge O of the triangular plate is horizontal and can be easily slid left and right to adjust the position. Then, the right sign B is adjusted in the right-left direction by sitting right, so that the sight line projection point of the sharp angle N point is caused to be aligned with and fall on the right line segment P on the road surface "visually" by the driver, and an intersection point Y point is generated (if two projection points are generated visually on the ground, the position of the sign B is adjusted by taking the left projection point close to the driver as the reference), and the position of the sharp angle N point is the position to be used, that is, the sharp angle N point is visually projected on the road surface and is the Y point. At the same time, the correctness of the positions of the two points M and N is confirmed again in the visual sense of the driver. In addition, the driver can slightly move the left mark A to the left and slightly move the right mark B to the right according to the driving habit of the driver so as to enlarge the collision avoidance space, but the driving precision is slightly reduced.

8. The sticker D is removed and extended as shown in FIG. 5 with point R at the tip of its notch to point M at the sharp corner of the left hand sign A: a part of the release paper A25 on the back of the lower end of the sticker D is torn off, then the triangular plate of the left sign A is pressed tightly by one hand to prevent moving, the point R at the tip of the notch of the sticker D is next to the point M of the sharp corner by the other hand, and the sticker D is lightly stuck on the glass to be used as a mark. The left flag a is then removed and the left auxiliary ruler C below it is removed, leaving only the locator sticker D on the left half of the glass.

9. The now removed release paper A25 on the back of the left side logo A was removed and glued back to the glass with its sharp corner M again in close proximity to the notch R of the positioning sticker D. And press the set square hard to stick firmly on the glass, and tear off the positioning sticker D, the left side sign A only remains in the upper left half of the glass at this moment. At the same time, the base of the left correction part S on the triangle is adjusted to make the tail end T of the left correction part bead string face the eyes of the driver, and make the driver' S sight line of the driver to make the tail end T of the left correction part bead string project on the larger bead U at the head end of the left correction part approximately, as shown in the left half of FIG. 6 and the angle of the left correction part S of FIG. 1.

10. The same steps as in both 8 and 9: similarly, the positioning sticker D which is just torn off is taken up again, and like the left half of FIG. 5, the R1 point at the tip of the notch extends to the sharp angle N point of the right sign B, one hand presses the right sign B tightly to prevent movement, the other hand presses the R1 point at the tip of the notch of the positioning sticker D to be next to the sharp angle N point, and the positioning sticker D is lightly stuck on the glass. The right side flag B is then removed and the right side auxiliary ruler J below it is removed, at which point the right half of the glass will only have the sticker D left.

11. The now removed release paper A25 on the back of the right-hand sign B was removed and glued back to the glass with its point angle N again in close proximity to the point R1 of the notch in the positioning sticker D. And press the set-square hard to stick firmly on the glass, and tear off the positioning sticker D, only left right side sign B on the right half on the glass at this moment. At the same time, the base of the right correction unit V is adjusted so that the tail end W of the right correction unit bead string is directed toward the eye, and the driver looks "at the driver" and makes the right correction unit bead string tail end W project on the larger bead Z at the head end of the right correction unit with his/her usual line of sight, as shown in the right half of fig. 6 and the angle of the right correction unit V of fig. 1. At this time, it is better to sit and check the tail end T of the left correction part bead string and the tail end W of the right correction part bead string at the correct projection positions again, so that the installation is completely proper. At this time, only the left sign a and the right sign B are firmly adhered to the lower side of the front windshield, as shown in fig. 6. Other elements can be folded and can be used for moving to other vehicles at a later date. The driver can see that two points of the left sharp corner M, N and the right sharp corner M, N are respectively projected on the road surface at the bottom end of the window for application. If you want to move the position slightly after just sticking A, B, please use the positioning sticker D to press the notch R or notch R1 to a predetermined position.

12. If another person can help the sticking when the installation is carried out, the installation time can be greatly shortened. If the ground in the vicinity of the vehicle is just a straight lane line H4, for example, a parking lot line or a road edge (see H4 in fig. 8). The window glass beside the driver seat can be lowered down, the head of the window glass is extended out of the window for driving, and the distance between the projection line H2 of the left vehicle body to the ground and the inner edge line of the lane line H4 is about 20 centimeters, so that the inner edge line of the lane line H4 can replace the chalk line H in the figure 2, the step of placing a 2-iron ring G, G1 on the lower vehicle, tensioning a thin line and drawing a line with chalk E in the item 2 is omitted, and only the chalk line on the other side needs to be drawn.

II, an operation instruction:

1. as shown in fig. 7: in the installation description, the two points X and Y naturally occurring on the road surface projected by the points M and N on the front windshield "in the driver's vision" are about 3 meters away from the front bumper of the vehicle (the vehicle types are slightly different, and the two actual distances from the left and right sides of the vehicle can be measured by the vehicle getting off, that is, the two points M, X on the left overlap and the two points N, Y on the right overlap in the "driver's vision"). That is to say, between the two road surface projection points of X and Y at about 3 meters in front of the vehicle, a front-guiding and planar invisible vehicle head with a ground projection range is generated, and a relatively clear planar driving reference is given to a driver: in various bad driving environments, if the invisible vehicle head does not touch the ground projection position of a person, a vehicle or an object in a short distance in front of the vehicle (such as the ground projection position S21 of an obstacle S2 in the right side of the front of the vehicle in FIG. 6) (that is, the ground projection position of the person, the vehicle or the object is "in the vision of the driver" and is not located between the two sharp corners M and N on the left and right of the vehicle), the vehicle does not collide with the person, the vehicle or the object even if the two sides are separated by only 50 centimeters and the vehicle continues to move straight ahead at a speed difference of 40 kilometers per hour); conversely, if the position of the projection of the human, vehicle or object onto the ground is between the two points X and Y on the road (e.g. the projection of the position S11 of the central obstacle S1 in front of the vehicle in fig. 6), i.e. "the driver is visually" between the two sharp corners M and N on the vehicle, the driver needs to brake or steer to prevent the occurrence of a collision, and the driver can avoid the collision by using the predicted path of the two sharp corners in the old and the old, and when the obstacle is visually collided with by the hidden vehicle, there is a distance of about 3 meters.

Similarly, when the vehicle runs on the road, the left sharp corner M point and the right sharp corner N point are kept at the same spacing distance with the left lane line H4 and the right lane line H4 in front of eyes, so that the vehicle can run at the center of the lane and can advance at high speed, and the vehicle is more accurate than people to command, thereby generating great on-site benefits. For example: on the mountain road without the guardrail, the bus is not easy to fall into the valley due to misestimation of the position of the front wheel when dodging, and the driver can foresee that the front right wheel of the bus will reach the position of a few centimeters on the left of the road surface projection point Y of the point N on the sharp corner on the sight line when continuing to move straight. As shown in fig. 6, the inclination of the left side a4 of the triangular plate of the left sign a also reflects the future straight direction of the left vehicle body on the road surface, and the "visual sense of the driver" is the inclined path to the right and upward direction, so a4 can represent the future road surface projection position and direction of the front section of the left vehicle body; the inclination of the right side edge B2 of the right side sign B triangle also reflects the future straight-going direction of the right side vehicle body of the vehicle, and the road surface is inclined to the left and upward from the "visual sense of the driver", so B2 can roughly represent the future road surface projection position and direction of the front section of the right side vehicle body. When the vehicle turns or goes in and out of a narrow parking space, the reference values of about 3 meters of distance between the X point and the Y point of the ground projection points of the two sharp-angle M points and the N point and the front bumper respectively can be utilized to make more accurate judgment so as to accelerate the turning and prevent the collision.

2. As mentioned at the beginning of the installation description: the term "in the driver's vision" refers to the vision and sight line generated by the seat position most used by drivers with different heights and habits during driving and the standard head position during driving in the most used posture. Therefore, in use, the left correction portion bead tail end T and the right correction portion bead tail end W in fig. 1 "in the view of the driver" should be approximately overlapped on the larger beads Z of the left correction portion bead head U and the right correction portion head, respectively. In practice, for example, when a shock is applied, the head of the driver may be greatly tilted to the left or right, which may cause the positions of the ground projection X and Y points of the two sharp angles M and N to be deviated, so that the left correction unit S and the right correction unit V are required: when the head of the driver is inclined left and right and is not in the conventional driving posture, the tail end T of the left correction part bead string can be easily perceived not to be projected on the head end U of the left correction part bead string; or the tail end W of the bead string of the right correction part is not projected on the larger bead Z at the head end of the right correction part, and even the difference is much different from the normal time, at this time, the driver is reminded to sit right immediately, and then the driver drives by using two sharp angles of the left M and the right N. If the vehicle is in a dim environment and the relative position between the tail end and the head end of the correction portion cannot be distinguished, the utility model is not used to drive the vehicle. The user needs to wear the model which can emit dim light at dark night.

3. The utility model discloses it is inboard to do to install the below at vehicle rear windshield to reverse a car in order to assist, its usage is the same as above.

4. When the vehicle is normally driven on a slow lane with a straight lane line H4 (as shown in H4 of FIG. 8), the driver can choose to use the left side rearview mirror to drive the left vehicle body to the ground projection line at a distance of about 20 cm from the right of the lane line H4 in a slow straight line, and the driver can confirm that the sharp corner M point of the left side mark is projected on the lane line H4 and the left correction part tail end T is projected on the left correction part bead bunch head end U just in the vision of the driver, which means that M, T two points are located at the correct positions and are not touched by other people such as cleaning people. Similarly, the driver can choose to use the right side rearview mirror to confirm approximately the correct position of N, M two points, and usually pay attention to the left and right signs not to be collided.

The above two descriptions are applicable to the use of one vehicle for mounting a set of auxiliary signs. But the same vehicle of the training class is frequently driven by different trainees in turn because of the driving of the vehicle. Therefore, the left sign a and the right sign B are not fixed properly, and need to be moved and adjusted in the left and right directions according to the driving habits and heights of the trainees. In order to reduce the trouble of adjusting the positions of the left-side sign a and the right-side sign B by reinstalling the same learner who drives the same vehicle again over several days, the auxiliary scale should be fixed to the learner-driven vehicle for a long period of time without being removed. And each student should remember the position of the left sign A and the right sign B on the auxiliary ruler corresponding to the scale, so as to adjust the applicable positions of the left sign A and the right sign B before class, and the left sign A and the right sign B are temporarily and tightly clamped on the auxiliary ruler and can be temporarily adhered on the windshield by using the transparent adhesive tape. However, the release paper a25 of the black double-sided tape a24 on the back of the left sign a or the right sign B as shown in fig. 14 is not removed for formal sticking, so that the release paper can be removed for another student to use when the student goes for a class.

Only because of the nearly 45 degree tilt of many car front windshields to the ground, the auxiliary ruler itself (as shown in 12 of fig. 9) and the surface 126 of the double-sided tape adhered thereon are also tilted to the ground by nearly 45 degrees. Such an angle would make it difficult for the driver to see the scale on the first surface 11 of the auxiliary scale, which is not conducive to the frequent use of trainees in car driving training classes.

Therefore, the auxiliary rule attached to the inclined windshield has a flat plate 130 extending downward from the auxiliary rule tip 127 in a direction approximately perpendicular to the ground or having an angle of elevation of approximately 10 degrees, and having a small width, as shown in fig. 10, except that the lower half 122 of the auxiliary rule is larger than the upper half 121 of the auxiliary rule and still has an L-shaped cross section, and the upper half 123 of the second surface of the auxiliary rule is formed to hold the base of the left sign a, the right sign B or the front sign. And scales and numbers are provided on a side 128 of the auxiliary scale facing the driver. The hollow portion 129 of the auxiliary rule on the back of the plate 130 extending from the auxiliary rule may be formed solid, as shown in the solid portion 1292 of the auxiliary rule in fig. 11. As shown in fig. 12, the numbers and the scales 131 are clearly displayed on the side 128 of the auxiliary scale facing the driver at a good angle, so that the driver can easily see the scales and numbers at any time, and each student can temporarily mount the left sign a or the right sign B before class for use.

Based on chinese utility model patent application No. 200920001510.5 "vehicle driving's vision auxiliary sign combination" one in the left side sign a right side sign B the left side is rectified the sign and is reached the right side is rectified the sign the place ahead is rectified sign and correction portion and all can be located the car or be located the car outside, consequently, the utility model discloses in the setting of supplementary chi and correction portion, be close windshield's car internal position.

In the present case, as shown in fig. 7, after the vehicle is driven straight ahead, the leftmost side of the total area projected to the ground forms a straight line, which is named as "extreme left collision line" 141; the rightmost side of which forms a straight line designated as "extreme right collision line" 142. In the above-mentioned "in the driver's vision", the eye position 14 is overlapped on the extension line of the "extreme left collision line" 141 by the ground projection X point of the "left marker" sharp angle M, and it is confirmed that the position of the "left marker a" is correct and has no deviation; similarly, in the driver's vision, the eye position 14 is superimposed on the extension line of the collision line 142 through the ground projection Y point of the sharp angle N of the right side marker B, and it is confirmed that the position of the right side marker B is correct and has no deviation. In addition, in the case of chinese utility model application No. 200920001510.5 "visual aid sign combination for vehicle driving", the left side sign a, the right side sign B, the left side correction sign, the right side correction sign, and the correction portion of the front sign are located close to the inner surface of the front windshield in some embodiments. When the correction portion has a light color surface, the image is reflected by the inner surface of the windshield, like a mirror surface, to the eyes of the driver when the correction portion is used in a clear weather, and thus a very bright reflection occurs, as shown by reflections S3 and V3 in fig. 13. The correction reflection is clear and is close to the vertex position M, N of the acute angle part and the large beads Z at the head end U and the head end of the left correction part and the right correction part respectively, so that the driver is easily disturbed to quickly distinguish important positions such as the vertex a21 of the acute angle part and the positioning point in an emergency state.

As shown in fig. 14, taking the left symbol as an example, the surface of the present disclosure (i.e. the reverse surface of the lower portion L of the correction portion) where the reflection occurs by making the correction portion face the sky surface S4 is not smooth and dark color with less reflection occurs, for example: black, dark brown, dark blue, dark purple, etc., thereby improving the above-described phenomenon of the visual disturbance due to the reflected image.

Concluding up the aforesaid, the utility model provides a vision auxiliary sign combination of vehicle driving wherein assists the improvement of chi and correction portion, more is suitable for providing the student of auttombilism training class and uses. And the reflection of the correction parts of the left sign A, the right sign B and the front correction sign is improved, and the phenomenon of disturbance in vision when a driver watches the signs is possibly generated.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made in the claims and the description of the present invention are also included in the scope of the present invention.
