Description

Technical Field

[0001] This application relates to the technical field of vehicles, and more specifically, to a tow hook cover assembly, a bumper assembly, and a vehicle. Background Art

[0002] When a vehicle breaks down, a tow hook is used to assist in towing the faulty vehicle. Generally, a tow hook hole is reserved at the vehicle bumper for assembling the tow hook. When the tow hook is not in use, the tow hook hole is covered to maintain the integrity of the vehicle appearance.

[0003] Existing tow hook covers are usually of a pry-open or lever structure. The pry-open or lever structure requires a pry-open notch to be reserved, which affects the vehicle appearance, and the tow hook cover is also prone to deformation. Summary of the Invention

[0004] This application provides a tow hook cover assembly, a bumper assembly, and a vehicle to solve the above technical problems.

[0005] The embodiments of this application are implemented as follows: A tow hook cover assembly includes a base, a cover body, a first rod, a second rod, and a power mechanism; along the thickness direction of the base, the cover body is movably disposed on one side of the base; the first rod includes a first end and a second end, the first end is rotatably connected to the base, and the second end rotates the cover body; the second rod is spaced from the first rod, the second rod includes a third end and a fourth end, the third end is rotatably connected to the base, and the fourth end is rotatably connected to the cover body; the power mechanism is disposed between the first rod and / or the second rod and the base.

[0006] In this way, a linkage mechanism is formed among the first rod, the second rod, the cover body and the base. When the cover body is in the closed state, the acting force of the power mechanism can keep the relative fixation among the first rod, the second rod and the base to maintain the closed state of the cover body. When an external force pushes the surface of the cover body and overcomes the acting force of the power mechanism, the cover body can realize a motion mode of approximate rotation plus translation under the action of the first rod and the second rod, and stably move to the open state to facilitate exposing the tow hook hole of the vehicle. After the tow hook is used up, the power mechanism can also drive the first rod and the second rod to reset, and then drive the cover body to move to the closed state. Specifically, when the power mechanism is arranged between the first rod and the base and the cover body is in the open state, after the external force acting on the cover body disappears, the acting force of the power mechanism on the first rod can drive the first rod to rotate relative to the base, and the cover body and the second rod move synchronously with the first rod. Under the cooperative action of the first rod and the second rod, the cover body performs a motion mode of approximate rotation plus translation, moves to the position of the tow hook hole, covers the tow hook hole, and returns to the closed state. When the power mechanism is arranged between the second rod and the base and the cover body is in the open state, after the external force acting on the cover body disappears, the acting force of the power mechanism on the second rod can drive the second rod to rotate relative to the base, and the cover body and the first rod move synchronously with the second rod, so that the cover body returns to the closed state. When the power mechanism is arranged between the first rod and the base and between the second rod and the base, the power mechanism can drive the first rod and the second rod to rotate relative to the base respectively to move the cover body so that it returns to the closed state. The tow hook cover assembly of the present application can open the cover body by an external force, and the cover body can automatically reset under the cooperative action of the power mechanism, the first rod and the second rod.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0030] Some embodiments of the present application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0031] See Figures 1 to 8 , this embodiment provides a bumper assembly 200, including a bumper body 201 and a tow hook cover assembly 100. The tow hook cover assembly 100 is configured on the bumper body 201, and specifically can be configured on the inner side of the bumper body 201. A tow hook hole 2011 is provided on the bumper body 201, and the tow hook cover assembly 100 is used to cover or open the tow hook hole 2011.

[0032] In some embodiments, the tow hook cover assembly 100 includes a base 10, a cover body 20, a first rod 30, a second rod 40, and a power mechanism 50. The base 10 is connected to the bumper body 201. The connection methods include but are not limited to welding, riveting, screw locking, or bonding, etc., to fix the relative positions of the base 10 and the bumper body 201. Along the thickness direction of the base 10, the cover body 20 is movably disposed on one side of the base 10. The first rod 30 includes a first end 31 and a second end 32. The first end 31 is rotatably connected to the base 10, and the second end 32 rotates the cover body 20. The second rod 40 is disposed at an interval from the first rod 30. The second rod 40 includes a third end 41 and a fourth end 42. The third end 41 is rotatably connected to the base 10, and the fourth end 42 is rotatably connected to the cover body 20. The power mechanism 50 is disposed between the first rod 30 and / or the second rod 40 and the base 10.

[0033] The base 10 is independently provided and assembled with the bumper body 201 when needed. A split structure is formed between the base 10 and the bumper body 201, and the two can be manufactured separately without integrally integrating a new structure on the bumper body 201, nor modifying the original design or production mold of the bumper body 201, etc. This is beneficial to reducing the manufacturing cost of the bumper body 201, simplifying the assembly process between the base 10 and the bumper body 201, and also facilitating the replacement of the tow hook cover assembly 100.

[0034] In this way, a linkage mechanism is formed among the first rod 30, the second rod 40, the cover body 20, and the base 10. When the cover body 20 is in the closed state, the power mechanism 50 can keep the relative positions of the first rod 30, the second rod 40, and the base 10 fixed to maintain the closed state of the cover body 20. When an external force pushes the outer surface of the cover body 20 and overcomes the acting force of the power mechanism 50, the cover body 20 can achieve a movement mode similar to rotation plus translation under the action of the first rod 30 and the second rod 40, and stably move to the inner side of the bumper body 201 to be in the open state, facilitating the exposure of the tow hook hole 2011 of the vehicle 300. After the trailer hook is used up, the power mechanism 50 can also drive the first rod 30 and the second rod 40 to reset, and then drive the cover body 20 to move to the closed state.

[0035] Specifically, when the power mechanism 50 is disposed between the first rod 30 and the base 10 and the cover body 20 is in the open state, after the external force applied to the cover body 20 disappears, the acting force of the power mechanism 50 on the first rod 30 can drive the first rod 30 to rotate relative to the base 10, and the cover body 20 and the second rod 40 move synchronously with the first rod 30. Under the cooperative action of the first rod 30 and the second rod 40, the cover body 20 performs a movement mode similar to rotation plus translation, moves to the tow hook hole 2011, covers the tow hook hole 2011, and returns to the closed state.

[0036] When the power mechanism 50 is disposed between the second rod 40 and the base 10, and when the cover body 20 is in a certain state, after the external force applied to the cover body 20 disappears, the acting force of the power mechanism 50 on the second rod 40 can drive the second rod 40 to rotate relative to the base 10, and the cover body 20 and the first rod 30 move synchronously with the second rod 40, so that the cover body 20 returns to the closed state.

[0037] When the power mechanism 50 is disposed between the first rod 30 and the base 10 and between the second rod 40 and the base 10, and when the cover body 20 is in a certain state, after the external force applied to the cover body 20 disappears, the power mechanism 50 can drive the first rod 30 and the second rod 40 to rotate relative to the base 10 respectively to move the cover body 20 so that it returns to the closed state.

[0038] The tow hook cover assembly 100 of the present application can open the cover body 20 by an external force, and the cover body 20 can automatically reset under the synergistic action of the power mechanism 50, the first rod 30, and the second rod 40 without secondary installation, with a simple structure and convenient use. There is no need to reserve a prying notch on the cover body 20, it is not easy to deform, and it is also beneficial to improve the appearance integrity of the vehicle 300. The cover body 20 is always connected to the bumper body 201 throughout the process, and there is no problem of falling off or being lost.

[0039] For the convenience of description, in the embodiments of the present application, the thickness direction of the base 10 may be the length direction Y of the vehicle 300, the width direction of the base 10 may be the width direction Y of the vehicle 300, and the height direction of the base 10 may be the height direction Z of the vehicle 300.

[0040] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments, a through groove 33 is provided on the first rod 30. The through groove 33 extends along the length direction of the first rod 30, and a sliding member 34 is provided in the through groove 33. The power mechanism 50 includes a first power member 51. One end of the first power member 51 is connected to the base 10, and the other end of the first power member 51 is connected to the sliding member 34. When the cover body 20 is in the closed state, the acting force of the first power member 51 pulls the sliding member 34 to one end of the through groove 33 close to the second end 32. When the cover body 20 is pushed open by an external force, the external thrust can be transmitted to the first rod 30 and the second rod 40 through the cover body 20, so that the first rod 30 rotates relative to the base 10 against the acting force of the first power member 51, and the second rod 40 and the cover body 20 move synchronously. During the rotation of the first rod 30, the sliding member 34 slides along the through groove 33 toward the first end 31 of the first rod 30 under the action of the first power member 51 until it abuts against one end of the through groove 33 close to the first end 31, achieving the effect of limiting the movement range of the cover body 20.

[0041] In some of these embodiments, the first power member 51 is a first elastic member, and the first elastic member includes, but is not limited to, structures such as springs, elastic bands, and elastic rods. When the cover body 20 is in the closed state, the first power member 51 uses elastic force to pull the sliding member 34 to one end of the through groove 33 close to the second end 32. At this time, the cover body 20 blocks the tow hook hole 2011, and the included angles between the first rod 30, the second rod 40 and the surface of the base 10 are acute angles. When an external force pushes the surface of the cover body 20 from the tow hook hole 2011, the thrust can be transmitted to the first rod 30 and the second rod 40 through the cover body 20, causing the first rod 30 and the second rod 40 to rotate relative to the base 10. Then, while driving the cover body 20 to move towards the inner side of the base 10, it also moves towards the side of the opening 11, so that the cover body 20 moves to one side of the tow hook hole 2011, exposing the tow hook hole 2011. During the rotation of the first rod 30, the first power member 51 is stretched, and the sliding member 34 slides along the through groove 33 towards the first end 31 of the first rod 30 under the pulling of the first power member 51 until it abuts against one end of the through groove 33 close to the first end 31, achieving the effect of limiting the movement range of the cover body 20. After the trailer hook is used up and withdrawn from the tow hook hole 2011, the first rod 30 can rotate towards the tow hook hole 2011 under the pulling of the first power member 51, thereby driving the cover body 20 to reset, covering the tow hook hole 2011, and returning to the closed state.

[0042] In other embodiments, when the cover body 20 blocks the tow hook hole 2011, the included angles between the first rod 30, the second rod 40 and the surface of the base 10 can also be right angles or obtuse angles, as long as there is a rotation space between the first rod 30, the second rod 40 and the base 10, and the present application is not limited thereto.

[0043] As Figure 4 shown, in some embodiments, a resisting portion 331 is further provided in the through groove 33, so that the sizes of the openings 11 on both sides of the through groove 33 are different along the thickness direction of the first rod 30. The sliding member 34 includes a first portion 341 and a second portion 342. The diameter of the first portion 341 is smaller than that of the second portion 342, and the first portion 341 extends out from one side of the through groove 33, and the first power member 51 is connected to the first portion 341. The second portion 342 is slidably disposed in the through groove 33, and the resisting portion 331 abuts against the side of the second portion 342 facing the first portion 341 to hold the sliding member 34 in the through groove 33 and prevent the sliding member 34 from falling off.

[0044] Please refer to Figure 5, in some embodiments, the power mechanism 50 includes a second power member 52. The second power member 52 is disposed at the connection between the first end 31 of the first rod 30 and the base 10; and / or, the second power member 52 is disposed at the connection between the third end 41 of the second rod 40 and the base 10. Thus, the second power member 52 can be disposed only at the first end 31 of the first rod 30 to provide power to drive the first rod 30 to rotate relative to the base 10, and the second rod 40 and the cover 20 move synchronously with the first rod 30 to realize the reset of the cover 20. Alternatively, the second power member 52 can also be disposed only at the third end 41 of the second rod 40 to provide power to drive the second rod 40 to rotate relative to the base 10, and the first rod 40 and the cover 20 move synchronously with the second rod 40 to realize the reset of the cover 20. Alternatively, the second power member 52 can also be disposed at the first end 31 of the first rod 30 and the third end 41 of the second rod 40 to provide power for the first end 31 of the first rod 30 and the third end 41 of the second rod 40 respectively, drive the first rod 30 and the second rod 40 to rotate relative to the base 10, and drive the cover 20 to reset.

[0045] In one of the embodiments, the second power member 52 is a second elastic member, and the second elastic member includes but is not limited to structures such as a torsion spring or a coil spring. Thus, the second power member 52 can provide an elastic torsional force at the first end 31 of the first rod 30 or the third end 41 of the second rod 40 to maintain the position of the first rod 30 and / or the second rod 40 when the cover 20 is in the closed state, or when the cover 20 is in the open state, cause the first rod 30 and / or the second rod 40 to rotate in the reverse direction or have a rotation tendency to assist the cover 20 to reset.

[0046] In some embodiments, the second power member 52 is a second elastic member, and the second elastic member is disposed at the connection between the third end 41 and the base 10, and specifically can be sleeved on the rotating shaft at the third end 41. A groove 43 is provided on one side of the second rod 40, and one end of the second elastic member abuts against the inner wall of the groove 43 to reduce the problem of the second elastic member slipping off. The other end of the second elastic member abuts against the surface of the base 10, so as to ensure that the end of the second elastic member can be effectively abutted and apply sufficient elastic torsional force to the third end 41.

[0047] In other embodiments, when the second elastic member is disposed at the connection between the first end 31 of the first rod 30 and the base 10, it can also be sleeved on the rotating shaft at the first end 31. One end of the second elastic member can abut against the inner wall of the through groove 33, and the other end can abut against the surface of the base 10.

[0048] In the embodiments of the present application, one of the first power member 51 and the second power member 52 can be selected for setting. In other embodiments, both the first power member 51 and the second power member 52 can also be disposed in the tow hook cover assembly 100 to improve the movement reliability of the cover 20.

[0049] In other embodiments, the power mechanism 50 may further include at least one power component such as a hydraulic component, an electric motor component, a strut component, and an elastic component. The installation positions of power components such as the hydraulic component, the electric motor component, the strut component, or the elastic component are similar to those of the first power component 51 or the second power component 52, so as to maintain the morphological positions of the first rod 30 and the second rod 40 when the cover body 20 is in the closed state, or to provide power to drive the first rod 30 and the second rod 40 to rotate and drive the cover body 20 to reset after the cover body 20 is opened.

[0050] Please refer to Figures 1 to 5 , in some embodiments, the cover body 20 includes a cover plate 21 and a connecting portion 22. The cover plate 21 is disposed opposite to the base 10, and the connecting portion 22 is disposed on a side of the cover plate 21 away from the base 10. The second end 32 of the first rod 30 and the fourth end 42 of the second rod 40 are rotatably connected to one side of the connecting portion 22. In the embodiments of the present application, the first rod 30 and the second rod 40 are disposed on the same side of the connecting portion 22 and are spaced apart. The first rod 30 may be disposed substantially parallel to the second rod 40. The parallelism error between the first rod 30 and the second rod 40 within the range of 0° - 5° can be regarded as being substantially parallel. Or, the included angle between the extension lines of the first rod 30 and the second rod 40 within the range of 175° - 185° can be regarded as being substantially parallel. In other embodiments, the first rod 30 can also be adjusted according to the assembly structure and the assembly space, and the first rod 30 and the second rod 40 are not parallel. The first rod 30 and the second rod 40 can rotate synchronously to ensure the stable movement of the cover body 20, and the present application is not limited thereto.

[0051] A quadrilateral linkage structure is generally formed among the base 10, the cover body 20 (or the connecting portion 22), the first rod 30, and the second rod 40. The cover body 20 is rotatably connected to the first rod 30 and the second rod 40, so that during the movement of the cover body 20, the cover plate 21 of the cover body 20 can be maintained substantially parallel to the surface of the base 10, thereby improving the stability of the cooperation between the cover plate 21 and the tow hook hole 2011 and reducing the scraping during the movement of the cover plate 21. The parallelism error between the cover plate 21 and the base 10 within the range of 0° - 5° can be regarded as being substantially parallel. Or, the included angle between the plane where the cover plate 21 is located and the plane where the surface of the base 10 is located within the range of 175° - 185° can be regarded as being substantially parallel.

[0052] In some embodiments, the connecting portion 22 includes a first side plate 221, a second side plate 222, and a third side plate 223 that are sequentially arranged on the peripheral side of the cover plate 21. The first side plate 221 and the second side plate 222 are arranged opposite to each other, and the third side plate 223 is connected between the first side plate 221 and the second side plate 222, so that the connecting portion 22 is generally a housing structure. On the one hand, it is convenient to connect the first rod 30 and the second rod 40, and on the other hand, it is beneficial to improve the structural strength of the cover body 20. The projections of the third side plate 223 and the cover plate 21 on the base 10 are adjacent. That is, the projection of the third side plate 223 on the surface of the base 10 is located on one side of the projection of the cover plate 21 on the surface of the base 10. In this way, the connecting portion 22 can be arranged to protrude from one side of the cover plate 21, which is convenient for assembling with the first rod 30 and the second rod 40.

[0053] The second end 32 of the first rod 30 is rotatably connected to the first side plate 221 or the second side plate 222; and / or, the fourth end 42 of the second rod 40 is rotatably connected to the first side plate 221 or the second side plate 222.

[0054] In an embodiment of the present application, the number of the first rods 30 is two, and the two first rods 30 are symmetrically arranged on the opposite sides of the connecting portion 22. One of the first rods 30 is rotatably connected to the first side plate 221 and the base 10, and the other first rod 30 is rotatably connected to the second side plate 222 and the base 10; the number of the second rods 40 can also be two, and the two second rods 40 are symmetrically arranged on the opposite sides of the connecting portion 22. One of the second rods 40 is rotatably connected to the first side plate 221 and the base 10, and the other second rod 40 is rotatably connected to the second side plate 222 and the base 10. The number of the first power members 51 can also be two, which are respectively connected to the two first rods 30 and the base 10.

[0055] The number of the second power members 52 can also be set corresponding to the number of the first rods 30 and / or the second rods 40. In this way, a quadrilateral link structure is formed on both opposite sides of the connecting portion 22, further improving the movement stability of the cover body 20.

[0056] In other embodiments, the number of the first rods 30 or the second rods 40 can also be one or more than two, and the number of the first power members 51 and / or the second power members 52 can also be increased or decreased correspondingly. As long as the design requirements are met, the present application is not limited thereto.

[0057] In some embodiments, the third side plate 223 can also be a curved surface structure. When the cover body 20 is in the open state, the curved surface structure of the third side plate 223 can avoid the internal structure of the vehicle 300.

[0058] In some other embodiments, the cover body 20 further includes a structural reinforcement member, which includes a first reinforcement member 23 and a second reinforcement member 24, respectively disposed on the surface of the cover plate 21 and the third side plate 223 facing away from the substrate, for increasing the structural strength of the cover body 20 and reducing the risk of deformation and cracking of the cover body 20 when impacted by an external force. The first reinforcement member 23 and the second reinforcement member 24 include, but are not limited to, structures such as reinforcing ribs, and are integrally formed on the inner surface of the cover body 20. It can improve the structural strength of the cover body 20 while not damaging the appearance integrity of the cover body 20. In other embodiments, the structural reinforcement member can also be disposed inside the first side plate 221 and / or the second side plate 222, as long as the design requirements are met, and the present application is not limited thereto.

[0059] Please refer to Figure 2 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the tow hook cover assembly 100 further includes an exterior trim panel 25, which is detachably disposed on the side of the cover body 20 facing the base 10. Specifically, the exterior trim panel 25 is detachably disposed on the side of the cover plate 21 facing the base 10. The connection manner between the exterior trim panel 25 and the cover plate 21 includes, but is not limited to, welding, riveting, screw locking, or gluing, etc. When the cover body 20 is in the closed state, the exterior trim panel 25 is at least partially located in the tow hook hole 2011, the side edge of the exterior trim panel 25 is spaced and cooperated with the side edge of the tow hook hole 2011, and the outer surface of the exterior trim panel 25 does not exceed the outer surface of the bumper body 201. Preferably, the outer surface of the exterior trim panel 25 is substantially flush with the outer surface of the bumper body 201 to maintain the integrity and aesthetics of the appearance of the vehicle 300. When the exterior trim panel 25 is damaged, the appearance of the vehicle 300 can also be maintained by replacing the new exterior trim panel 25.

[0060] The exterior trim panel 25 is connected to the cover plate 21 of the cover body 20 to form a double-layer structure. By adjusting the structure of the exterior trim panel 25, such as adjusting the thickness, shape, etc. of the exterior trim panel 25, it can be adjusted according to the assembly gap between the cover plate 21 and the bumper body 201. The exterior trim panel 25 is used to fill the surface difference gap between the cover plate 21 and the outer surface of the bumper body 201, so as to realize the adjustment of the surface difference gap between the cover plate 21 and the outer surface of the bumper body 201.

[0061] Furthermore, the projection of the cover plate 21 on the inner surface of the bumper body 201 overlaps with the tow hook hole 2011, and the projected area of the cover plate 21 is larger than the area of the tow hook hole 2011. Thus, when the cover body 20 is in the closed state, the part of the outer surface of the cover plate 21 that exceeds the edge of the exterior trim panel 25 can abut against the inner surface of the bumper body 201 under the action of the power mechanism 50, avoiding the cover body 20 protruding from the outer surface of the bumper body 201.

[0062] Please refer to again Figures 1 to 5, in some embodiments, an opening 11 is provided on the base 10, and the towing hook hole 2011 on the bumper body 201 is exposed from the opening 11. The first rod 30 and the second rod 40 are located on one side of the opening 11. The cover body 20 has an open state and a closed state. When the cover body 20 is in the closed state, a part of the cover body 20 shields the opening 11. When the cover body 20 is in the open state, the cover body 20 exposes the opening 11.

[0063] In an embodiment of the present application, the first rod 30 and the second rod 40 are located on one side of the opening 11 along the width direction of the base 10 (the vehicle width direction X). During the opening process of the cover body 20, it can move along the width direction of the base 10 (the vehicle width direction X) to the side of the opening 11. In other embodiments, the first rod 30 and the second rod 40 can also be located on one side of the opening 11 along the height direction of the base 10 (the vehicle height direction Z). During the opening process of the cover body 20, it can move along the height direction of the base 10 (the vehicle height direction Z) to the side of the opening 11.

[0064] In an embodiment of the present application, one end of the first power member 51 connected to the base 10 is located on the side of the opening 11 away from the first rod 30, so as to pull the cover body 20 to move towards the opening 11.

[0065] In some embodiments, the base 10 is further provided with a first support 12, a second support 13, and a third support 14. The first support 12 is used for rotatably connecting the first end 31 of the first rod 30. The rotating shaft between the first end 31 of the first rod 30 and the first support 12 can be integrally formed with the first end 31, or integrally formed with the first support 12, or can be a split structure with the first rod 30 or the first support 12. The rotating shaft between the second end 32 of the first rod 30 and the cover body 20 can also be integrally formed with the second end 32, or integrally formed with the connecting portion 22 of the cover body 20, or can be a split structure with the first rod 30 or the cover body 20. The present application is not limited thereto. The second support 13 is used for rotatably connecting the third end 41 of the second rod 40. The rotating shaft arrangement structures at the third end 41 and the fourth end 42 of the second rod 40 are substantially the same as those of the first rod 30, and will not be described in detail here. The third support 14 is used for positioning one end of the first power member 51 away from the first rod 30. The arrangements of the first support 12, the second support 13, and the third support 14 enable the first rod 30, the second rod 40, and the first power member 51 to be installed with the corresponding supports through simple docking, which is beneficial to reducing the assembly difficulty of the base 10 with the first rod 30, the second rod 40, etc., and improving the assembly efficiency.

[0066] In other embodiments, the base 10 may not be provided with the opening 11. At this time, the base 10 is arranged on one side of the towing hook hole 2011. When the cover body 20 is in the closed state, the cover plate 21 of the cover body 20 extends out of one side of the base 10 and cooperates with the towing hook hole 2011.

[0067] Please refer to Figure 9 , an embodiment of the present application further provides a vehicle 300, including a vehicle body 301 and the tow hook cover assembly 100 or the bumper assembly 200 described in the above embodiment. The tow hook cover assembly 100 or the bumper assembly 200 is disposed on the vehicle body 301.

[0068] A new tow hook cover structure is designed in the tow hook cover assembly 100, the bumper assembly 200 and the vehicle 300 of the present application, and the traditional prying or rocker structure is cancelled. In the tow hook cover assembly 100 of the present application, the cover body 20 is opened by an external force pushing towards the inside of the base 10, reducing the layout space limitation of the cover plate 21 at the tow hook hole 2011, and making it easier to match the cover plate 21 with the tow hook hole 2011. Under the action of the first rod 30 and the second rod 40, the cover body 20 can achieve a movement mode of approximate rotation plus translation, stably move to the side of the tow hook hole 2011, and remain in the closed state under the action of the power mechanism 50, or automatically reset the opened cover body 20. The structure is simple and the operation is convenient. The entire outer surface of the cover plate 21 is an area where it can be pressed and pushed, improving the user experience. There is no need to reserve a prying notch on the cover body 20, which is not easy to deform and is also beneficial to improving the appearance integrity of the vehicle 300. When the cover body 20 is in the opened state, it will not be exposed outside the bumper body, reducing the risk of accidental collision damage or scratching of the cover body 20.

[0069] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
