Detailed ways

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding technical features.

FIG. 1 is an exploded schematic diagram of an energy tank filling lid mechanism for a vehicle according to an embodiment of the present invention. As shown in the figure, the energy tank filling opening cover mechanism includes a cover body 1, a control mechanism 2 and the like.

It can be understood that the cover body 1 is suitable for covering the filling port of the energy tank of the vehicle, and plays the roles of protection, sealing and dustproof. Those skilled in the art can design the cap body with reference to the common shapes of fuel tank caps of gasoline vehicles in the prior art, such as but not limited to circle, ellipse, square, oblong and so on. For the aesthetics and integrity of the vehicle body, it is preferably designed such that the outer periphery of the cover body 1 is aligned with the fitting port of the vehicle body at the filling port when the cover body is closed, and the outer surface follows the configuration of the vehicle body.

The control mechanism 2 is fixed on the body of the vehicle adjacent to the filling port of the energy tank of the vehicle, for example, on the side close to the filling port, and can be assembled from a series of components for controlling and driving the movement of the cover body 1 . Specifically, the control mechanism 2 is connected to the eccentric position of the cover body 1 to drive it to rotate laterally eccentrically, so that the rotation displacement of the cover body 1 can open the filling port of the energy box to allow energy supplementation. The control mechanism 2 in the figure is an exemplary implementation, and those skilled in the art may consider other forms of control mechanism to realize the lateral rotation of the cover body 1 .

The opening method of the cover body 1 in the present invention is different from the most common outward turning method in the prior art, but adopts the opening method of turning up sideways. According to the energy tank filling lid mechanism of the present invention, the opening and closing of the lid body 1 is controlled by the drive control mechanism 2 of the self-locking motor 25, and the rotation control of the lid body 1 is unidirectional, that is, it can only be controlled by a circuit The positive and negative rotation of the self-locking motor realizes the rotation of the cover. When the cover 1 is closed, the self-locking motor can play a locking role; that is, when the cover 1 is closed, under the reverse self-locking action of the worm gear inside the self-locking motor, the external force cannot open the cover Body, so as to realize the energy box charging port cover mechanism and its internal self-locking and anti-destructive functions.

According to the energy tank filling lid mechanism of the present application, after receiving the opening command (the opening command can be applied in a wired or wireless manner), the self-locking motor 25 used to provide power will drive the control mechanism 2, and then the control mechanism 2 controls And drive the cover body 1 so that it rotates to the side of the filling port while moving out from the filling port of the energy tank of the vehicle body, thereby moving away from the filling port and revealing the energy filling port, so that the operator can refuel, inflate or charge the energy tank . The self-locking motor 25 may be directly fixed to the vehicle body or indirectly fixed to the vehicle body through other fastening components.

Those skilled in the art can also imagine that the energy tank filling port cover mechanism is designed so that the control mechanism 2 controls and drives the cover body 1 to rotate to the side of the filling port after moving a certain distance from the energy tank filling port of the vehicle body; Those skilled in the art can think of specific implementation methods (for example, designing a straight section along the axial direction of the non-self-locking screw mechanism at the end of the helical guide rail), so details will not be repeated here.

The above-mentioned design of the energy tank filling lid mechanism for vehicles can be applied to gasoline vehicles, gas vehicles and new energy electric vehicles.

Referring to FIG. 1 , in the illustrated exemplary embodiment, the control mechanism 2 is adapted to make the cover body 1 rotate laterally while being driven outward, which may include a bottom cover 21 , a non-self-locking screw mechanism 22 , A compression spring 23, a pull wire 24 and a self-locking motor 25 fixed to the bottom cover 21, etc.

In this example, the bottom cover 21 is the part on which the energy tank filling port mechanism is installed to the body of the vehicle, the control mechanism 2 is fixed beside the filling port of the energy tank of the vehicle through the bottom cover 21, and the cover body 1 is It is fixed together with one of the components of the control mechanism 2, that is, the movable sleeve 222, so that the working position of the cover body 1 can be determined.

It can be seen from the figure that the non-self-locking screw mechanism 22 includes a fixed sleeve 221 and a movable sleeve 222 , and the fixed sleeve 221 and the movable sleeve 222 are engaged in a non-self-locking screw connection. Under the action of the compression spring 23 in the figure, the movable sleeve 222 can rotate and eject from the fixed sleeve 221 along the spiral guide rail. The fixed sleeve 221 is fixed to the bottom cover 21 , and the movable sleeve 222 is fixed to an eccentric position on the cover body 1 . In the illustrated example, in order to expose the filling port as much as possible after the cover body 1 is rotated, the movable sleeve 222 is designed to be far away from the center of the cover body 1, and one end of the movable sleeve 222 is preferably fixed to the center of the cover body 1. near the edge. Although an exploded view is used as an example in the figure, those skilled in the art can understand the assembly structure and functional principle of the energy tank filling opening mechanism according to the present invention in combination with the description in this specification.

Two ends of the compression spring 23 respectively abut against the bottom cover 21 and the movable sleeve 222 , and apply opposite thrusts to the bottom cover 21 and the movable sleeve 222 respectively. It can be understood that when the compression spring 23 pushes the bottom cover 21 and the movable sleeve 222 respectively, the movable sleeve 222 will rotate and rise inside the fixed sleeve 221, and drive the cover body 1 to move outward from the filling port of the energy tank. Rotate sideways. According to the illustrated example, the compression spring 23 is preferably a helical spring; other forms of compression springs are also feasible. Moreover, the two ends of the compression spring 23 can also abut against the bottom cover 21 and the cover body 1 respectively, and since the cover body 1 and the movable sleeve 222 are fixed together, the cover body can also be rotated away from the filling port of the energy tank.

The pull wire 24 in the figure is pulled between the cover body 1 or the movable sleeve 222 and the self-locking motor 25 fixed on the bottom cover 21; according to the illustrated example, the pull wire 24 can extend through the bottom cover 21, the spring 23 and the non- Self-locking screw mechanism 22. It can be understood that after receiving the command to close the cover 1 , the self-locking motor 25 pulls and retracts the pull wire 24 , so that the cover 1 and the movable sleeve 222 compress the compression spring 23 and move toward the bottom cover 21 . Due to the screw connection between the movable sleeve 222 and the fixed sleeve 221, the movable sleeve 222 will rotate while retracting the fixed sleeve 221 and moving towards the bottom cover 21, so that the cover body 1 is moving closer to the body. Simultaneously (at this time the movable sleeve 222 can be fully retracted into the fixed sleeve 221) rotate to the position that covers the filling port of the energy tank. The advantage of using the self-locking motor 25 to pull the pull wire 24 is that the speed is controllable, and the opening and closing speed of the cover body 1 can be smooth, and the opening and closing speed can be adjusted. According to the embodiment shown in the figure, the pull wire 24 can be connected to the self-locking motor 25 through the wire pulley 26, which can prevent the pull wire 24 from being entangled or even knotted or detached from the motor to affect the operation effect.

After receiving the command to open the cover body 1, the locking mechanism (it is a commonly used mechanism, not shown in the figure) is unlocked, and the self-locking motor 25 releases the pull wire 24 controllably, and the movable sleeve 222 and the cover body 1 compress the spring Under the effect of the outward thrust of 23, it is bounced up and rotated at a certain angle to complete the action of opening the cover body 1. It can be understood that adjusting the spring-up speed of the cover body 1 according to the helix angle can make the whole movement process moderate in speed; according to the circumferential angle between the two ends of the screw, the final rotation angle of the movable sleeve 222 and the cover body 1 can be set. In an optional embodiment, the rotation angle of the cover body 1 can be designed to be between 120° and 240°, preferably between 150° and 210°, more preferably 180°. As previously mentioned, this can be achieved by determining the relative circumferential angles at both ends of the screw in the non-self-locking screw mechanism 22; for example, by setting the circumferential angle, the fixed sleeve in the non-self-locking screw mechanism 22 can The rotatable angle between 221 and the movable sleeve 222 is between 120° and 240°, preferably between 150° and 210°, more preferably 180°. According to the teaching here, those skilled in the art can set other suitable rotatable angles for the cover body 1 .

In addition, in order to realize the non-self-locking helical angle, the following settings can be considered. Assuming that the friction coefficient between the contact pairs of the helical materials is μ, in order to ensure the smooth rotation of the energy tank filling cover while popping up, there is α>arc tan μ (where α is the helix angle). Under the premise of satisfying this condition, the helix angle α can be as large as possible within the allowable range of the structure. The above can ensure that under the elastic force of the compression spring and the guiding action of the contact pair, the filling port cap can be bounced up and rotated at the desired angle at the same time.

Fig. 2 is an exploded schematic view of the non-self-locking screw mechanism in the energy tank filling lid mechanism in Fig. 1, which specifically shows an embodiment of the non-self-locking screw mechanism.

As shown in the figure, the helical engagement in the non-self-locking screw mechanism 22 is realized by the helical guide rail 2221 on the movable sleeve 222 and the guide block 2211 on the fixed sleeve 221, wherein the helix angle of the helical guide rail 2221 can be mentioned above The described method is determined. In the illustrated embodiment, the spiral guide rail 2221 may be a two-line guide rail, and the spiral guide rail 2221 is preferably in the form of a groove. Correspondingly, the number of guide blocks 2211 is also two, and their positions correspond to each line of the spiral guide rail. In order to adapt to the grooved spiral guide rail 2221, the guide block 2211 is preferably in the form of a protrusion. According to the figure, it can be understood that when the fixed sleeve 221 and the movable sleeve 222 are joined together, the two protrusions 2211 fall into the corresponding spiral guide rails (grooves) 2221 respectively, and when the movable sleeve 222 is driven When moving relative to the fixed sleeve 221 , the protrusion 2211 will move along the helical guide rail 2221 , so that the movable sleeve 222 rotates circumferentially while moving axially along the fixed sleeve 221 .

Those skilled in the art can think of forms of multi-wire spiral guide rails, such as but not limited to three-wire, four-wire and so on. These multi-thread spiral guide rails are preferably evenly distributed along the circumferential direction on the movable sleeve. It is conceivable that in these cases, the number of guide blocks will be correspondingly multiple, such as but not limited to three, four, etc.; their circumferential positions also need to be adapted to those of the multi-wire spiral guide rail. It can be understood that an appropriate increase in the number of spiral guide rails and guide blocks is beneficial to ensure a more stable relative movement between the movable sleeve and the fixed sleeve.

Based on the above description, those skilled in the art can make further improvements to the non-self-locking screw mechanism. For example, the spiral guide rail can be designed as a convex guide rail, and the guide block can have grooves suitable for the convex guide rail; the number can also be two, three, four or more to ensure the working stability of the mechanism. In addition, those skilled in the art can also imagine that the spiral guide rail can also be designed on the fixed sleeve, and the guide block can be designed on the movable sleeve.

In the figure, the fixed sleeve is sleeved outside the movable sleeve. Those skilled in the art can understand that in an optional embodiment, the movable sleeve can also be designed to be sleeved outside the fixed sleeve, which does not affect the implementation of the present invention and also falls within the protection scope of the present invention Inside.

As shown in FIG. 2 , the non-self-locking screw mechanism 22 includes a stop structure 2222 that prevents disengagement of the fixed sleeve and the movable sleeve. As shown in the figure, the limiting structure 2222 is a flange located at an end of the movable sleeve 222 away from the cover body 1 . It can be understood that the limiting structure can also be selected in other ways, for example, it is only provided on the part of the closed groove at the end of the spiral guide rail away from the cover body. It is also conceivable for those skilled in the art to provide additional components to prevent disengagement of the fixed sleeve and the movable sleeve; details will not be repeated here.

It can be understood from the above description that the energy tank filling lid mechanism of the present invention adopts an automatic spiral pop-up structure, and the opening process of the filling lid includes always facing outwards without turning over after opening; the filling lid is always kept relatively close to the vehicle body. fit, the operator will not be scratched. The automatic spiral pop-up structure has a linear and beautiful opening speed during use, and the front faces outward after opening, and the appearance is relatively unified with the body part, which ensures the aesthetics of the structure. In addition, the design of the present invention uses the self-locking motor to control the spring to push the fuel tank cap to unscrew, and the opening action is completed in one step, without the need for the user to perform redundant actions. Through remote or wireless operation, the design according to the present invention enables the user to complete the opening and closing action of the energy tank filling port without getting off the vehicle.

Combining the above description, those skilled in the art can understand that the energy tank filling opening cover mechanism of the present invention is used in vehicles. When it is assembled in a vehicle, its cover body is suitable for covering the filling port of the energy tank of the vehicle, such as a refueling port, an air filling port or a charging port, etc., and its bottom cover is suitable for fixing the body on the side of the filling port place. The control mechanism of the energy tank filling port cover mechanism can control and drive the cover body to rotate sideways so as to open and close the filling port.

The technical scope of the present invention is not limited to the content in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should belong to within the scope of the present invention.
