detailed description

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

1 is an exploded perspective view of an energy tank filling flap mechanism for a vehicle in accordance with an embodiment of the present invention. As shown, the energy tank filling flap mechanism includes a cover 1 and 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 box of the vehicle, and functions as protection, sealing, dustproof and the like. Those skilled in the art can design the cover by referring to the shape of a gasoline fuel tank filler cap that is common in the prior art, such as, but not limited to, circular, elliptical, square, oblong, and the like. 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 opening of the vehicle body at the filling opening in the closed state, and the outer side surface conforms to the configuration of the vehicle body.

The control mechanism 2 is fixed to the body of the vehicle adjacent to the filling port of the energy tank of the vehicle, for example, fixed to the side of the filling port, and can be assembled from a series of components for controlling and driving the movement of the cover 1. Specifically, the control mechanism 2 is coupled to the eccentric position of the cover 1 to drive its lateral eccentric rotation so that the rotational displacement of the cover 1 can open the filling port of the energy tank to allow supplemental energy. The control mechanism 2 in the figure is an exemplary embodiment, and those skilled in the art may consider implementing the lateral rotation of the cover 1 by other forms of control mechanisms.

The opening manner of the lid body 1 in the present invention is different from the most common way of outward turning in the prior art, but a side-screw opening method is employed. The energy tank filling flap mechanism according to the present invention, wherein the opening and closing of the lid body 1 is controlled by the self-locking motor 25 driving control mechanism 2, and the screwing control of the lid body 1 is unidirectional, that is, only by circuit control The forward and reverse rotation of the self-locking motor realizes the rotation of the cover body. When the cover body 1 is in the closed state, the self-locking motor can play the locking function; that is, when the cover body 1 is in the closed state, under the reverse self-locking action of the internal worm gear of the self-locking motor, the external force cannot open the cover. Body, thereby achieving the function of the energy box charging port cover mechanism and its internal self-locking and anti-destruction.

According to the energy tank filling flap mechanism of the present application, after receiving an opening command (which can be applied by wire or wirelessly), the self-locking motor 25 for supplying power will drive the control mechanism 2, and thus the control mechanism 2 And driving the cover body 1 to rotate to the side of the filling port while moving from the filling port of the body energy box, thereby removing from the filling port and exposing the energy filling port, so that the operator can refuel, inflate or charge the energy box. . The self-locking motor 25 can be fixed directly to the vehicle body or indirectly to the vehicle body by other fastening components.

It is also conceivable by those skilled in the art that the energy tank filling flap mechanism is designed such that the control mechanism 2 controls and drives the lid body 1 to rotate to the side of the filling port after moving a distance from the body energy tank filling port; A specific implementation can be envisaged by those skilled in the art (for example, designing a straight section along the axial direction of the non-self-locking screw mechanism at the end of the spiral guide), and in this regard, no further details are provided herein.

The above design of the energy tank filling and capping mechanism for a vehicle can be applied to a gasoline vehicle, a gas vehicle, and a new energy electric vehicle.

Referring to FIG. 1, in the illustrated exemplary embodiment, the control mechanism 2 is adapted to rotate the cover 1 to the side while being driven to move outward, which may include a bottom cover 21, a non-self-locking thread mechanism 22, The compression spring 23, the wire 24, the self-locking motor 25 fixed to the bottom cover 21, and the like.

In the present example, the bottom cover 21 is a component to which the energy tank filling port mechanism is attached to the vehicle body, and the control mechanism 2 is fixed by the bottom cover 21 to the filling port of the energy tank of the vehicle, and the cover 1 is The movable sleeve 222 is fixed together with one of the components of the control mechanism 2, so that the working position of the cover 1 can be determined.

As can be seen from the figure, the non-self-locking screw mechanism 22 includes a fixed sleeve 221 and a movable sleeve 222, and a screw joint between the fixed sleeve 221 and the movable sleeve 222 in a non-self-locking manner. Under the action of the compression spring 23 in the figure, the movable sleeve 222 can be rotated and ejected from the fixed sleeve 221 along the spiral guide. The fixing sleeve 221 is fixed to the bottom cover 21, and the movable sleeve 222 is fixed to an eccentric position on the cover 1. In the illustrated example, in order to expose the filling opening as much as possible after the rotation of the cover 1 , the movable sleeve 222 is designed to be away from the center of the cover 1 , and preferably one end of the movable sleeve 222 is fixed to the cover 1 . Near the edge. Although the figures are illustrated in an exploded view, the assembly structure and functional principle of the energy tank filling port mechanism according to the present invention can be understood by those skilled in the art in conjunction with the description in this specification.

Both ends of the compression spring 23 abut against the bottom cover 21 and the movable sleeve 222, respectively, and apply opposite thrusts to both 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 be rotated and raised in the fixed sleeve 221, and the cover body 1 is moved outward from the energy tank filling port. Rotate sideways. According to the illustrated example, the compression spring 23 is preferably a coil spring; other forms of compression springs are also possible. Moreover, the two ends of the compression spring 23 can also abut the bottom cover 21 and the cover body 1, respectively. Since the cover body 1 and the movable sleeve 222 are fixed together, the cover body can also be rotated and moved away from the energy tank filling port.

The pull wire 24 in the drawing is drawn between the cover 1 or the movable sleeve 222 and the self-locking motor 25 fixed to 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 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 cable 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 toward the bottom cover 21, so that the cover 1 is moved closer to the vehicle body. At the same time (at this time the movable sleeve 222 can be fully retracted into the fixed sleeve 221), it is rotated to a position where the energy tank filling port is covered. 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 made smooth, and the opening and closing speeds can be adjusted. According to the embodiment as shown, the wire 24 can be connected to the self-locking motor 25 via the wire wheel 26, which can prevent the wire 24 from being tangled or even knotted or detached from the motor to affect the operational effect.

After receiving the command to open the cover 1, the locking mechanism (which is a common mechanism, not shown) is unlocked, the self-locking motor 25 controllably releases the opening wire 24, and the movable sleeve 222 and the cover 1 are in the compression spring. Under the action of the outward thrust of 23, it is bounced and rotated by a certain angle to complete the opening operation of the cover body 1. It can be understood that adjusting the speed at which the cover body 1 bounces according to the helix angle can make the whole motion process moderate and moderate; according to the circumferential angle between the two ends of the spiral, the final rotation angle of the movable sleeve 222 and the cover body 1 can be set. In an alternative embodiment, the angle of rotation of the cover 1 can be designed to be between 120 and 240 degrees, preferably between 150 and 210 degrees, more preferably 180 degrees. As previously mentioned, this can be achieved by determining the relative circumferential angles of the ends of the helix 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 be made The angle of rotation between the 221 and the movable sleeve 222 is between 120 and 240 degrees, preferably between 150 and 210 degrees, more preferably 180 degrees. Those skilled in the art can set other suitable rotatable angles for the cover 1 in accordance with the teachings herein.

In addition, in order to achieve a non-self-locking helix angle, the following settings can be considered. It is assumed that the friction coefficient between the contact pairs of the spiral material is μ, and in order to ensure the bouncing and the energy tank filling cover rotates smoothly, there is α>arc tan μ (where α is a spiral angle). Under the premise of satisfying this condition, the helix angle α can be as large as possible within the range allowed by the structure. The above can ensure that the filling port cover is rotated and the desired angle is rotated under the guiding action of the compression spring and the contact pair.

2 is an exploded perspective view of the non-self-locking screw mechanism of the energy tank filling flap mechanism of FIG. 1, in which an embodiment of the non-self-locking screw mechanism is specifically illustrated.

As shown in the figure, the helical engagement in the non-self-locking screw mechanism 22 is achieved by the spiral guide 2221 on the movable sleeve 222 and the guide block 2211 on the fixed sleeve 221, wherein the spiral angle of the spiral guide 2221 can be above The method described is determined. In the illustrated embodiment, the helical track 2221 can be a two wire guide and the helical track 2221 is preferably in the form of a groove. Accordingly, the number of the guide blocks 2211 is also two, and their positions correspond to the spiral guides per line, respectively. In order to fit the grooved spiral guide 2221, the guide block 2211 is preferably in the form of a projection. It can be understood from the illustration that when the fixing sleeve 221 and the movable sleeve 222 are joined together, the two protrusions 2211 respectively fall into the corresponding spiral guides (grooves) 2221, and the movable sleeve 222 is driven. When moving relative to the fixed sleeve 221, the projection 2211 will move along the spiral guide 2221 such that the movable sleeve 222 rotates circumferentially while moving axially along the fixed sleeve 221.

One skilled in the art would appreciate the form of a multi-wire helical track such as, but not limited to, three wires, four wires, and the like. These multi-wire helical guides are preferably uniformly distributed circumferentially on the movable sleeve. It is conceivable that in these cases the number of guide blocks will also be correspondingly plural, such as but not limited to three, four, etc.; its circumferential position also needs to be adapted to the circumferential position of the multi-wire helical guide. It will be appreciated that an appropriate increase in the number of helical guides and guide blocks facilitates 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 can be designed as a male guide rail, and the guide block can have a groove adapted to the male guide rail; the number can also be two, three, four or more to ensure the working stability of the mechanism. In addition, it is also conceivable by those skilled in the art that the spiral guide can also be designed on the fixed sleeve and the guide block can be designed on the movable sleeve.

In the illustration, the fixing sleeve is sleeved outside the movable sleeve. It can be understood by those skilled in the art that in an alternative 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 scope of protection of the present invention. Inside.

As shown in FIG. 2, the non-self-locking screw mechanism 22 includes a stop structure 2222 that prevents the fixed sleeve and the movable sleeve from disengaging. As shown, the stop structure 2222 is a flange located at one end of the movable sleeve 222 remote from the cover 1. It can be understood that the limiting structure can also be selected in other ways, for example, only the portion of the spiral guide that closes the groove at the end away from the cover. It is also contemplated by those skilled in the art that additional components are provided to prevent the retaining sleeve and the movable sleeve from disengaging; no further details are provided herein.

It can be understood from the above description that the energy tank filling flap mechanism of the present invention adopts an automatic spiral bouncing structure, and the filling flap cover is opened and always faces outward without being turned over; the filling flap and the body body are always relatively attached. It will not cause the operator to be scratched. The automatic spiral bouncing structure has a linear opening appearance during use, and the front surface is outwardly opened, and the appearance and the body part have a relatively high uniformity, thereby ensuring the aesthetic appearance of the structure. In addition, the design of the present invention is driven by the self-locking motor control spring to push the fuel tank cap to rotate, and the opening action is performed in one step, without the user performing unnecessary actions. By remote or wireless operation, the design in accordance with the present invention allows the user to complete the opening and closing of the energy tank filling flap without having to get off the vehicle.

In connection with the above description, those skilled in the art will appreciate that the energy tank filling flap mechanism of the present invention can be used in a vehicle. When it is assembled to a vehicle, the cover is adapted to cover the energy tank filling port of the vehicle, such as a fuel filler port, a gas filling port or a charging port, and the bottom cover is adapted to be fixed to the body of the filling port side. At the office. The control mechanism of the energy tank filling flap mechanism can control and drive the lateral rotation of the lid to open and close the filling port.

The technical scope of the present invention is not limited to the above description, and various modifications and changes can be made to the above-described embodiments without departing from the technical idea of the present invention. Within the scope of the invention.
