Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The technical contents of the present invention will be described in detail by specific embodiments.
Fig. 1 is a schematic structural diagram of a stereo navigation system according to an embodiment of the present invention. Fig. 2 is a schematic top view of the stereo navigation system shown in fig. 1. As shown in fig. 1 and 2, the stereoscopic navigation system includes an acquisition unit and a flexible display panel 10, and the acquisition unit and the flexible display panel 10 are electrically connected. The obtaining unit is used for obtaining the current road information of the vehicle, and the flexible display panel 10 can present a shape consistent with the shape of the current road according to the current road information of the vehicle.
According to the stereo navigation system provided by the embodiment of the invention, the flexible display panel 10 can present the shape consistent with the shape of the current road according to the current road information of the vehicle, so that the shape of the current road of the vehicle is displayed to a user in a physical shape change mode of the display panel, a real and visual feeling can be given to the user, more accurate information can be fed back to the user, the driving safety is improved, and the user experience is improved.
In one embodiment, the display surface of the flexible display panel 10 displays current road information of the vehicle. Therefore, the three-dimensional navigation system displays the current road condition of the vehicle to a user in a mode of combining the physical shape change and the display of the display panel, and further improves the driving safety and the user experience.
In order to realize the change of the physical shape of the flexible display panel, as shown in fig. 1, the stereo navigation system further includes a base station and a plurality of adjusting columns 11 disposed on the flexible display panel 10, a driving mechanism for driving the adjusting columns 11 is disposed on a mounting surface of the base station, and the adjusting columns 11 drive the flexible display panel 10 to bend and deform under the driving of the driving mechanism, so that the flexible display panel 10 can present a shape consistent with the shape of the current road.
In one embodiment, as shown in fig. 1 and 2, the display surface of the flexible display panel 10 is disposed perpendicular to the submount mounting surface. A plurality of adjusting columns are sequentially arranged on the flexible display panel 10, and the adjusting columns 11 are arranged along the direction perpendicular to the installation surface of the base platform. The driving mechanism comprises a first movement mechanism and a second movement mechanism corresponding to the adjustment column 11. One end of the adjusting column 11, which faces the mounting surface, is connected with a corresponding first motion mechanism, and the first motion mechanism is connected with a second motion mechanism. The first movement mechanism is used for adjusting the position of the adjusting column 11 in the first direction X according to the current road information, and the second movement mechanism and the first movement mechanism work in a coordinated manner to adjust the position of the adjusting column 11 in the second direction Y. When the position of the adjusting column 11 changes, the adjusting column 11 will drive the flexible display panel to bend flexibly, so that the flexible display panel 10 can take a shape consistent with the shape of the current road when viewed in a direction perpendicular to the mounting surface of the base, as shown in fig. 1 and fig. 2. In fig. 1 and 2, the first direction is an X direction, the second direction is a Y direction, the second direction is perpendicular to the first direction, and both the first direction and the second direction are directions parallel to the base mounting surface. The mode that the position of the adjusting column is changed is driven by combining the first movement mechanism and the second movement mechanism, the physical shape change of the flexible display panel is realized, and the flexible display panel is simple in structure and easy to realize.
Fig. 3 is a rear schematic view of the flexible display panel in fig. 1 in an unbent state. As shown in fig. 3, the adjusting columns 11 are disposed on a side of the flexible display panel 10 facing away from the display surface in a direction perpendicular to the mounting surface of the base, so that the adjusting columns 11 do not affect the display of the display surface. In the direction (i.e. in the Z direction) perpendicular to the mounting surface of the base, the flexible display panel 10 is completely fixed on the adjusting column 11, that is, the flexible display panel 10 is fixedly connected with the adjusting column 11 from one end to the other end (from the left edge to the right edge in fig. 3) in the Z direction, so that when the position of the adjusting column 11 is changed, each part of the flexible display panel in the Z direction can be driven to deform, and the deformation uniformity of the flexible display panel is ensured. As shown in fig. 3, a plurality of adjustment columns 11 are uniformly spaced on the flexible display panel 10 in the second direction, so that the flexible display panel can be more smoothly deformed.
Fig. 4 is a schematic diagram of a stereo navigation system in another embodiment. In another embodiment, as shown in fig. 4, the display surface of the flexible display panel 10 may be disposed parallel to the base mounting surface. It is easily understood that the display surface of the flexible display panel is parallel to the base mounting surface, which means that the display surface of the flexible display panel in a planar state (i.e., without bending deformation) is parallel to the base mounting surface. A plurality of regulation posts 11 set gradually on flexible display panel 10, regulation post 11 is perpendicular to the installation face sets up. The drive mechanism may include a third motion mechanism and a second motion mechanism corresponding to the adjustment post. The third moving mechanism is configured to adjust the position of the adjusting column in a third direction (i.e., the Z direction) according to the current road information, and the second moving mechanism and the third moving mechanism cooperate to adjust the position of the adjusting column in the second direction Y, so that the flexible display panel can assume a shape corresponding to the shape of the current road as viewed in a direction parallel to the mounting surface of the base, as shown in fig. 4. The third direction Z is a direction perpendicular to the base table mounting surface, and the second direction Y is a direction parallel to the base table mounting surface. In this embodiment, the adjustment column 11 may be a plate-like structure so as to be supported on the lower side of the flexible display panel in the X direction. In the embodiment of fig. 4, a plurality of adjustment columns 11 are arranged on the side of the flexible display panel facing away from the display surface in a direction perpendicular to the mounting surface of the base. The plurality of adjustment columns 11 are disposed on the flexible display panel 10 at uniform intervals in the second direction, so that the flexible display panel can be more smoothly deformed.
It is easily understood that the road shape refers to a curved shape of a road, for example, a vehicle turns right and then turns left at the front of the road, and in fig. 2, the flexible display panel 10 takes a shape corresponding to the shape of the current road, that is, the flexible display panel 10 takes a shape of turning right and then turning left from bottom to top, and the shape of the flexible display panel 10 corresponds to the shape of the current block.
As shown in fig. 1 and 2, the second moving mechanism includes 2 second sliding grooves 31 disposed on the mounting surface, two second sliding grooves 31 are disposed on two opposite sides of the flexible display panel 10 along the second direction, and second sliding blocks 32 are disposed in the two second sliding grooves 31, respectively. The first moving mechanism includes a first sliding chute 33, the first sliding chute 33 is disposed along a first direction, and two ends of the first sliding chute 33 are respectively fixedly connected with a second sliding block 32 disposed in the second sliding chute 31. The first moving mechanism further comprises a first sliding block 34 arranged in the first sliding groove 33, and the adjusting column 11 is fixedly connected with the first sliding block 34. The first movement mechanism further comprises a first motor, and the first motor is in transmission connection with the first slide block 34. Under the driving of the first motor, the adjusting column 11 moves along the first direction X in the first sliding slot 33 along with the first sliding block 34, so as to adjust the position of the adjusting column 11 in the first direction.
In an embodiment, when the adjusting columns 11 move along the first direction X in the first sliding grooves 33 along with the first sliding blocks 34, since the adjusting columns 11 are all connected through the flexible display panel 10, the adjusting columns 11 move in the first direction X to generate a component force along the second direction Y to the flexible display panel 10, under the action of the component force in the second direction Y, the second sliding blocks 32 slide in the second sliding grooves 31, so that the positions of the adjusting columns 11 in the second direction Y are adjusted, and the adjusting columns 11 drive the flexible display panel to realize flexible bending deformation.
In another embodiment, the second moving mechanism further includes a second motor, and the second motor may be in transmission connection with the first sliding chute 33 or the second sliding block 32 through a transmission mechanism to drive the first sliding chute to move along the second direction. Therefore, the first motor and the second motor are matched with each other, the positions of the adjusting columns 11 in the first direction and the second direction are adjusted, and flexible bending deformation of the flexible display panel is achieved.
It will be readily appreciated that the cooperation of the slide and the runner can provide a good motion guide, and in other embodiments, other guide structures, such as a guide shaft and a guide bearing, can be used to provide motion guide. The transmission mechanism can adopt screw rod and nut transmission, belt transmission and other transmission mechanisms.
In fig. 1 and 2, the number of the adjusting columns 11 is 3, and correspondingly, the first moving mechanism and the second moving mechanism are respectively in three groups, and each group is correspondingly connected with the adjusting column 11. The flexible display panel 10 has a flexible and bendable characteristic, so that when the position of the adjusting column 11 is changed, the flexible display panel 10 can be bent and deformed. It is easily understood that the number of the adjusting columns 11 can be determined according to actual needs.
In order to ensure the position stability of the flexible display panel, the stereo navigation system further includes a positioning column 12 disposed at an end portion of the flexible display panel 10, wherein the positioning column 12 is perpendicular to the mounting surface of the base, as shown in fig. 1, 2 and 3. In this embodiment, the two ends of the flexible display panel are both provided with positioning posts 12. Two positioning columns 12 are disposed at two ends of the flexible display panel 10 along the second direction Y. The stereo navigation system further comprises a fourth motion mechanism correspondingly connected with the positioning column 12. The fourth movement mechanism is used to adjust the position of the end of the flexible display panel 10 in the second direction Y and maintain the position of the end of the flexible display panel 10 in the first direction X. Since the number of the positioning columns 12 is two, correspondingly, the number of the fourth movement mechanisms is also two. Therefore, the positions and the shapes of the two end parts of the flexible display panel can be stabilized, and unpredictable deformation of the end parts of the flexible display panel is avoided, so that the flexible display panel can be smoothly bent and deformed.
It is easily understood that in the embodiment shown in fig. 4, the positioning columns 12 may be plate-shaped structures so as to be supported at the left and right ends of the flexible display panel in the X direction.
As shown in fig. 1 and 2, the fourth moving mechanism may include 2 third sliding grooves 41 disposed on the mounting surface of the base, two third sliding grooves 41 are disposed on two opposite sides of the flexible display panel 10 along the second direction, and third sliding blocks 42 are disposed in the two third sliding grooves 41, respectively. The fourth motion mechanism further includes a fixing rod 43, the fixing rod 43 is disposed along the first direction, and two ends of the fixing rod 43 are respectively fixedly connected with the third sliding block 42. Two ends of the flexible display panel 10 are respectively fixedly connected to the corresponding fixing rods 43 through the positioning posts 12. The deformation of the flexible display panel 10 generates a component force to the positioning column 12 along the second direction, and under the action of the component force in the second direction, the third slider 42 slides in the third sliding slot 41, so that the position of the positioning column 12 in the second direction is adjusted, and the positions of the two ends of the flexible display panel in the second direction Y are adjusted. Since the positions of both ends of the flexible display panel are maintained in the first direction X, the end of the flexible display panel is prevented from being unexpectedly warped.
It is easily understood that in other embodiments, the third sliding chute 41 and the second sliding chute 31 located on the same side of the flexible display panel may share a sliding chute with a longer length, so as to simplify the assembly structure of the stereo navigation system.
In fig. 2, the current driving direction of the vehicle on the road is, for example, when there is a right turn at the next intersection or the same road, the first adjusting post 111 moves to the left in the first direction, and the second adjusting post 112 and the third adjusting post 113 move to the right in the first direction along with the changing direction of the road, that is, the first adjusting post 111 slides to the left in the first sliding slot under the driving of the corresponding first motor, and the second adjusting post 112 and the third adjusting post 113 slide to the right in the first sliding slot under the driving of the corresponding first motor. The flexible display panel 10 assumes a shape that is consistent with the current driving road, such as the shape of the flexible display panel 10 in fig. 2.
FIG. 5 is a schematic diagram of electrical connections of the stereo navigation system. In one embodiment, the stereo navigation system further includes an obtaining unit 50, and the obtaining unit 50 is configured to obtain current road information of the vehicle. The acquisition unit 50 is electrically connected to the flexible display panel. The acquisition unit 50 is electrically connected to the first motor. The first motor drives the first movement mechanism to move according to the current road information of the vehicle so as to adjust the positions of the adjusting columns 11 in the first direction and the second direction, and physical deformation of the flexible display panel is achieved, so that the flexible display panel 10 presents a shape consistent with the current driving road of the vehicle.
Fig. 6 is a schematic diagram of a shape change of the flexible display panel during driving of the vehicle. As shown in fig. 6, during the driving process of the vehicle, the current position of the vehicle is changed continuously, which results in that the current driving road of the vehicle is changed continuously, so that the shape of the flexible display panel is changed along with the change of the current driving road of the vehicle, and the shape and the direction of the current driving road are intuitively shown to the user.
As shown in fig. 5, the stereo navigation system further includes a display control unit 60, the display control unit 60 is electrically connected to the obtaining unit 50 and the flexible display panel 10, and the display control unit 60 is configured to control the flexible display panel 10 to display the current road information of the vehicle according to the current road information of the vehicle, so that the current road information of the vehicle can be displayed on the display surface of the flexible display panel 10. The physical curvature of the flexible display panel may cause curvature of the display surface such that a user may visually perceive the road curvature. For example, in fig. 6, when the road turns left at a, since the flexible display panel is bent to the left at the position corresponding to a, when the driver views the display surface of the display panel, the driver can feel that the road turns left at a, so that the user can more intuitively obtain the current road information to perform the pre-operation in advance, thereby improving the driving safety.
In one embodiment, the stereoscopic navigation system further includes a collision avoidance unit 70. The collision avoidance unit 70 includes an image acquisition subunit and a sensing subunit. An image acquisition sub-unit (e.g., a camera) may be provided at the front and/or rear end of the vehicle, and the anti-collision unit 70 is electrically connected with the display control unit 60. The acquisition subunit is used for extracting image information in front of the vehicle in real time, recording road conditions in real time, and identifying obstacles (such as sundries, steps, bulges, potholes and the like) in front of the vehicle, and the sensing subunit is used for calculating and obtaining obstacle information, such as information of the outline size, height or depth of the obstacles, the relative position and distance between the obstacles and the vehicle, and the like. The display control unit 60 controls the flexible display panel 10 to display the obstacle information on the display surface according to the obstacle information in front of the vehicle, so that the road information displayed by the flexible display panel more truly reflects the actual road information. For example, in fig. 6, the collision avoidance unit recognizes that there are an obstacle D and an obstacle E in front of the vehicle, and the display screen displays obstacle information. In one embodiment, the display scale of the obstacle information is the same as the display scale of the vehicle on the display surface, so that a user can accurately judge the distance between the current vehicle and the obstacle, whether the vehicle can directly pass through the obstacle or needs to avoid the obstacle, and the like by watching the display panel. In one embodiment, the display control unit may further control the flexible display panel to display an obstacle indication line according to the obstacle information, for example, in fig. 6, when the vehicle approaches the obstacle D, the display panel displays the obstacle indication line to show the user whether the obstacle is located on the driving route, so as to facilitate the user to perform an avoidance operation and improve driving safety.
FIG. 7 is a schematic diagram of a comparison of vehicle chassis and obstacle height. In one embodiment, the collision avoidance unit is further configured to instruct the user whether to avoid the collision avoidance according to the information of the obstacle in front of the vehicle. After the collision avoidance unit 70 identifies the obstacle information in front of the vehicle, it prompts the user whether the vehicle can pass through the obstacle directly by comparing the obstacle height or depth information with the vehicle chassis height. When the height or the depth of the barrier meets the safety threshold, the three-dimensional navigation system prompts a user that the barrier can directly pass through the barrier, and when the height or the depth of the barrier does not meet the safety threshold, the three-dimensional navigation system prompts the user to avoid the barrier, so that the risk that the barrier damages a vehicle can be avoided, and the driving safety is further improved.
Fig. 8 is a schematic diagram of a display surface partition display of the flexible display panel. When the vehicle passes through a narrow space or a place with more obstacles, the anti-collision unit can also identify the information of the obstacles around the vehicle. Specifically, the image acquisition subunit is further used for identifying obstacles around the vehicle (such as other vehicles around the vehicle, buildings, larger obstacles and the like) in real time, and the sensing subunit is further used for calculating and obtaining obstacle information around the vehicle, such as information of the contour size, height or depth of the obstacle, the relative position and distance between the obstacle and the vehicle and the like. The display control unit controls the display surface of the flexible display panel to perform partition display according to the information of the obstacles around the vehicle, as shown in fig. 8, the middle position of the display surface, namely the display area B, displays the safe driving route of the vehicle, and the two sides of the safe driving route, namely the display areas a and C, display the three-dimensional size of the obstacles.
Fig. 9 is a display screen of the flexible display panel when the vehicle backs up and enters the garage. In one embodiment, as shown in fig. 9, when the vehicle backs up and enters the garage, the collision-prevention unit collects obstacles (an obstacle a, an obstacle B, and an obstacle C) around the vehicle, and calculates the distances between the obstacle a, the obstacle B, and the obstacle C and the vehicle. At the moment, the display surface of the display panel displays in a partition mode, the safe driving route of the vehicle is displayed in the middle of the display surface, and obstacles are displayed on two sides of the safe driving route, so that driving boundaries are drawn on the ground similarly to the case of learning the vehicle, and collision is avoided. The display proportion of the barrier is consistent with that of the vehicle, so that a user can timely adjust the driving direction according to the safe driving route until the vehicle safely enters the target parking area, and the collision with the barrier is avoided.
In one embodiment, the anti-collision unit is electrically connected with a speed measuring device of the vehicle, the anti-collision unit can obtain the speed of the vehicle from the speed measuring device, whether collision risks exist is judged according to the speed of the vehicle and the distance between the vehicle and surrounding objects, and if the collision risks exist, the vehicle is protectively and autonomously braked to avoid collision.
Fig. 10 is a schematic top view of the stereo navigation system installed in a vehicle, and fig. 11 is a schematic side view of the stereo navigation system installed in the vehicle. When the stereo navigation system of the present embodiment is installed in a vehicle, the stereo navigation system is installed in the vehicle body at the front right of the driver as shown in fig. 10, and the height of the stereo navigation system is lower than the height of the horizontal line of sight of the driver as shown in fig. 11. In fig. 10, the stereo navigation system viewing direction forms an angle α with the forward driving direction, typically α is less than or equal to 45 °. In fig. 11, the stereo navigation system viewing direction forms a first angle β with the driver's horizontal line of sight, typically β is 15 ° to 45 °. By the arrangement, a driver can observe the shape change of the flexible display panel, can avoid a blind area and well observe the current road information displayed on the display surface. The three-dimensional navigation system is arranged in the right front of the driver and is lower than the horizontal sight position of the driver, and the driver can observe the physical shape of the flexible display panel and the current road information displayed by the display surface at the same time, so that the driver can distinguish and judge according to the current road information and in combination with the physical property change of the flexible display panel, the mental dispersion is reduced, the accident is reduced, and the driving safety is improved. When the stereo navigation system is specifically installed, the stereo navigation system can be installed in a vehicle as required, and a driver can observe the deformation shape of the flexible display panel and the current road information displayed on the display surface.
In one embodiment, the flexible display panel is a flexible OLED display panel. The flexible display panel may also be other types of flexible display panels as long as they can be flexibly bent and deformed.
