[0026] Please also read Figure 1 and Figure 2The trailer hook cover structure provided by the utility model is now described. The trailer hook cover structure comprises: a trailer hook cover 1 and a rotation drive mechanism 2. The rotation drive mechanism 2 drives the trailer hook cover 1 to rotate clockwise or counterclockwise through a pull rod 3 to open or close a trailer hook cover hole 61 provided on a bumper body 6.

[0027] The trailer hook cover plate 1 structure provided by the utility model drives the trailer hook cover plate 1 to automatically rotate and open or close the trailer hook cover plate hole 61 on the bumper body 6 through the rotating drive mechanism 2. There is no need to manually pry open the trailer hook cover plate 1 with tools, and the opening process will not be time-consuming and laborious, and the paint surface of the bumper will not be damaged, thereby effectively preventing the risk of damaging the appearance of the entire vehicle; at the same time, it also avoids the risk of damage to the trailer hook cover plate 1 due to pressing fatigue, and will not affect the fitting clearance and surface height difference between the trailer hook cover plate 1 and the bumper, thereby enhancing the exquisite perception of the appearance of the entire vehicle.

[0028] Of course, the implementation of this application requires the use of control elements, wherein the button for controlling the opening and closing action of the rotary drive mechanism 2 is integrated on the control panel of the cab. This application can realize the driving of the rotary drive mechanism 2 by using the most basic motor 21 opening and closing control, and therefore, those skilled in the art can implement it.

[0029] In some embodiments, see Figure 1 and Figure 2 The rotary drive mechanism 2 includes a motor 21 and a rotary shaft 22 drivingly connected to the motor 21; one end of the pull rod 3 is connected to the rotary shaft 22, and the other end is connected to the trailer hook cover 1.

[0030] The opening and closing process of the trailer hook cover 1 based on the above-mentioned rotation drive mechanism 2 is as follows: under normal circumstances, the trailer hook is not used, and the trailer hook cover 1 is blocked in the trailer hook cover hole 61 of the bumper body 6. When the vehicle needs to be towed or needs to tow other vehicles, the trailer hook cover 1 needs to be opened to facilitate the installation of the trailer hook on the trailer hook installation hole inside the trailer hook cover hole 61. At this time, the driver controls the motor 21 to work, and the rotation of the motor 21 drives the rotating shaft 22 to rotate counterclockwise, and the rotation of the rotating shaft 22 drives the pull rod 3 and the trailer hook The cover plate 1 rotates counterclockwise around the rotating shaft 22 for a certain angle until the trailer hook cover plate 1 does not block the trailer hook cover plate hole 61, and the motor 21 stops working; after the trailer hook is used, the driver starts the motor 21, and the motor 21 drives the rotating shaft 22 to rotate clockwise, and the rotating shaft 22 drives the pull rod 3 and the trailer hook cover plate 1 to rotate clockwise around the rotating shaft 22 for a certain angle until the trailer hook cover plate 1 completely blocks the trailer hook cover plate hole 61, so that the trailer hook cover plate 1 is covered in the trailer hook cover plate hole 61, and the motor 21 stops working.

[0031] The rotating shaft 22 may be connected to the main shaft of the motor 21 via a spline sleeve or a coupling.

[0032] In some embodiments, in combination Figure 1 and Figure 2 The rotary drive mechanism 2 further includes a support 5 and a support block 4 supporting the rotary shaft 22; the motor 21 and the support block 4 are both mounted on the support 5, and a support hole for the rotary shaft 22 is provided on the support block 4. The support block 4 is equivalent to the function of a bearing seat, and the support of the rotary shaft 22 can ensure that the rotary shaft 22 line will not deflect, thereby ensuring that the trailer hook cover 1 will not deviate when closed, and the trailer hook cover hole 61 cannot be completely closed.

[0033] Optionally, two support blocks 4 are provided to ensure the coaxiality of the rotating shaft 22, and at the same time, the connection position between the pull rod 3 and the rotating shaft 22 is between the two support blocks 4. At the same time, one of the support blocks 4 can be provided at the end of the rotating shaft 22 away from the motor 21, as a support and axial limit for the rotating shaft 22. For example, in theory, the main shaft of the motor 21 can be oriented in any direction while ensuring the rotation radius with the pull rod 3 as the radius. Therefore, the rotating shaft 22 is located below the motor 21. At this time, the lower end of the rotating shaft 22 needs to be limited to prevent the rotating shaft 22 from falling. At this time, a shoulder or radial pin that abuts against the support block 4 can be provided at the lower end of the rotating shaft 22.

[0034] Furthermore, the support block 4 can be directly welded to the support 5, or can be clamped or fastened to the support 5 by screws. The shape of the support block 4 can be rectangular, semicircular or trapezoidal.

[0035] In some embodiments, a bearing that slides with the rotating shaft 22 is disposed in the support hole, thereby ensuring the sensitivity of the rotation of the rotating shaft 22 and avoiding the phenomenon that the trailer hook cover 1 is not opened smoothly due to the stuck of the rotating shaft 22.

[0036] In some embodiments, see Figure 1 and Figure 2 , a mounting sleeve 23 is provided on the rotating shaft 22, the mounting sleeve 23 is key-connected to the rotating shaft 22, and a radial locking pin is also provided between the mounting sleeve 23 and the rotating shaft 22 to ensure the synchronous rotation of the two; one end of the pull rod 3 is fixed on the mounting sleeve 23 to ensure the synchronous rotation of the pull rod 3 and the rotating shaft 22. Through the detachable connection between the mounting sleeve 23 and the rotating shaft 22, since the trailer hook cover 1 is an appearance part, when it is damaged or deformed by external force collision or pressing, the trailer hook cover 1 can be replaced by removing the mounting sleeve 23.

[0037] In order to facilitate the disassembly of the mounting sleeve 23, the support block 4 can be snap-connected to the support 5 or fixed to the support 5 with screws. Because the trailer hook cover 1 is small in size and light in weight, the sizes of other connecting rods, the support block 4, and the rotating shaft 22 do not need to be too large to support the opening or closing of the trailer hook cover 1.

[0038] Of course, a more convenient disassembly method does not require disassembly of the support block 4, but rather designs the mounting sleeve 23 to have an axially slit opening, and fastens the opening with bolts so that the mounting sleeve 23 is wrapped around the rotating shaft 22.

[0039] Furthermore, the outer shape of the mounting sleeve 23 is a ball head shape, and the threaded holes are arranged along the radial direction of the ball head, so it has a longer length to facilitate reliable connection of the pull rod 3.

[0040] Optionally, an inner gear ring is provided in the mounting sleeve 23, and an outer gear ring matching the inner gear ring is provided on the rotating shaft 22, so that gear meshing can be formed between the mounting sleeve 23 and the rotating shaft 22, and the transmission mode of the gear meshing has a self-locking property. When the trailer hook cover 1 is closed or opened, it can ensure the firmness of the closing and the position will not change when opened.

[0041] In some embodiments, a threaded hole is provided on the mounting sleeve 23, and one end of the pull rod 3 is threadedly engaged with the threaded hole. In this case, when the trailer hook cover 1 needs to be replaced, the pull rod 3 only needs to be unscrewed from the mounting sleeve 23.

[0042] As mentioned above, since the trailer hook cover 1 is small in size and the sizes of the matching parts are not large, if only threaded holes are provided on the mounting sleeve 23, the engagement length between the pull rod 3 and the threaded holes may be insufficient, resulting in loose fixation. Therefore, a radially extending internal threaded sleeve may be provided on the mounting sleeve 23 to cooperate with the installation of the pull rod 3, thereby improving the firmness of the connection of the pull rod 3.

[0043] It should be noted that there are also multiple ways for the rotary drive mechanism 2 provided in the present application to drive the trailer hook cover 1 to rotate and open. In the connection method of the motor 21, main shaft, rotating shaft 22 and pull rod 3 adopted in the present application, the rotating shaft 22 is perpendicular to the trailer hook cover hole 61 or the center line of the trailer hook cover 1. During the closing process, the angle (acute angle or right angle) between the trailer hook cover 1 and the bumper body 6 gradually changes until the trailer hook cover 1 is in contact with the bumper body 6. In another way of rotating and opening, the trailer hook cover 1 can always be parallel to the bumper body 6. In this case, the main shaft of the motor 21 is parallel to the trailer hook cover hole 61 or the center line of the trailer hook cover 1. In this case, the pull rod 3 The rod 3 is always parallel to the bumper body 6. In this case, the rotation drive mechanism 2 can still include a motor 21, a rotating shaft 22 connected to the main shaft of the motor 21, and a pull rod 3 connected to the rotating shaft 22. The pull rod 3 is key-connected to the rotating shaft 22, and the pull rod 3 has a certain axial movement freedom in the direction of the rotating shaft 22, so that the pull rod 3 can be lifted by the electric push rod, so that the trailer hook cover 1 can first be separated from the trailer hook cover hole 61 and then rotated. When the trailer hook cover 1 needs to be closed, when the trailer hook cover 1 is rotated to the trailer hook cover hole 61, the electric push rod is also required to push the pull rod 3 and then drive the trailer hook cover 1 to be pushed into the trailer hook cover hole 61, so as to keep the outer surface of the trailer hook cover 1 connected with the appearance of the bumper body 6.

[0044] Optionally, the installation position of the electric push rod or a linear actuator such as a cylinder can be installed on a component different from the motor 21. For example, the motor 21 is installed on the inner wall of the bumper body 6, and the linear actuator is installed on the body sheet metal inside the bumper body 6.

[0045] It should be explained that this embodiment can be reproduced through the description text without providing specific drawings.

[0046] In some embodiments, see Figure 1 and Figure 2 The two ends of the pull rod 3 respectively have a first supporting arm 31 and a second supporting arm 32 bent to the same side, the first supporting arm 31 is connected to the rotating shaft 22, and the second supporting arm 32 is connected to the trailer hook cover plate 1. Specifically, the structure of the pull rod 3 is formed with two bends, which can reduce the rotation angle of the trailer hook cover plate 1 compared with the straight pull rod 3. At the same time, when the trailer hook cover plate 1 is covered on the trailer hook cover plate hole 61, the second supporting arm 32 forms a vertical supporting force on the trailer hook cover plate 1, thereby avoiding the risk of the trailer hook cover plate 1 being easily collapsed and deformed due to collision or pressure by external force.

[0047] In some embodiments, the trailer hook cover plate 1 has an outer boss adapted to the trailer hook cover plate hole 61 and a limiting step abutting against the inner wall of the bumper body 6. The outer boss on the trailer hook cover plate 1 is responsible for the seam with the trailer hook cover plate hole 61 and the surface of the bumper body 6, while the limiting step is responsible for limiting the trailer hook cover plate 1 when it is closed, thereby avoiding the risk of the trailer hook cover plate 1 protruding outward beyond expectations.

[0048] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0049] Based on the same inventive concept, the embodiment of the present application also provides a bumper structure, see Figure 3 to Figure 4 , including a bumper body 6 , on which a trailer hook cover plate hole 61 is provided; the trailer hook cover plate 1 is structurally mounted on the inner wall of the bumper body 6 .

[0050] The bumper structure provided by the embodiment of the utility model is equipped with the trailer hook cover 1 that can be opened and closed automatically. The operation of opening and closing the trailer hook cover 1 is time-saving and labor-saving, and will not damage the bumper paint or cause surface difference between the two, thereby ensuring the appearance quality of the bumper body 6.

[0051] Among them, the motor 21 in the rotation drive mechanism 2 can be directly fixed to the inner wall of the bumper body 6 by bolts, or a support 5 (a plate-like structure can be selected, also referred to as a base plate) can be installed on the bumper body 6, bolts can be welded on the support 5 or threaded holes can be set, and the motor 21 can be installed on the support 5. The support 5 can increase the structural rigidity of the installation part of the motor 21 and provide more reliable support for the motor 21; at this time, the support 5 can be welded to the bumper body 6 or connected by bolts.

[0052] Similarly, the support block 4 can be welded to the support 5 or the bumper body 6, or fixed by screws or buckles.

[0053] Regarding the installation direction and position of the rotating drive mechanism 2 on the bumper body 6, it only needs to be installed on a concentric circle with a certain radius centered on the trailer hook cover hole 61. It can be installed above, below, or on the left, or on the right, or on the upper left, or on the lower right, etc. of the trailer hook cover hole 61, because no matter where it is, as long as it is within a certain rotation radius, the trailer hook cover 1 can be tightly covered on the trailer hook cover hole 61.

[0054] The functions of the outer boss and the limit step provided on the trailer hook cover 1 are as follows: the edge of the outer boss can be seamlessly connected with the inner wall of the trailer hook cover hole 61, and the outer surface of the outer boss can be smoothly transitioned with the outer surface of the bumper body 6, so as to ensure the appearance quality of the whole vehicle and avoid surface difference or gap; since the trailer hook cover 1 covers the trailer hook cover hole 61 from the inside to the outside, in terms of design, although the electronic control motor 21 is designed with a perfect running route to ensure the closure of the trailer hook cover 1 and the trailer hook cover hole 61, in case of electronic control failure or malfunction, the trailer hook cover 1 may be out of control and extend outward more. At this time, the limit step is used as a mechanical limit. When the limit step abuts against the inner wall of the bumper body 6, the trailer hook cover 1 is subjected to resistance and stops moving, thereby ensuring the reliability of the closing action of the trailer hook cover 1.

[0055] Based on the same inventive concept, an embodiment of the utility model further provides a vehicle, comprising the bumper structure.

[0056] The vehicle provided by the embodiment of the utility model adopts this bumper structure, which can prevent the appearance quality of the bumper from being damaged when installing the trailer hook, thereby effectively preventing damage to the appearance of the entire vehicle and enhancing the exquisite perception of the entire vehicle.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
