Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to a tailgate assembly for a vehicle and the vehicle itself. Background Technology

[0002] As people's car usage scenarios become increasingly diverse, their demands for self-driving camping, in-car rest, and in-car entertainment are becoming more prominent, and the car trunk plays an important role in these scenarios. The car trunk has evolved from a storage space into a multifunctional living space, with the trunk cover enhancing its functionality and practicality by adding components.

[0003] In related technologies, most traditional car trunk covers are laid flat inside the trunk. Some can be adjusted in height, but not in angle, which is inconvenient to use. Therefore, how to improve the ease of use of trunk covers is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a tailgate assembly and vehicle for use, which improves ease of use.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a tailgate assembly for a vehicle, including a box body, a cover plate, and a support portion: the box body has a recess, the upper end of which is open to form an opening; the cover plate is rotatably disposed on the box body to open or close the opening; along the length direction of the support portion, the support portion has a first end and a second end disposed opposite to each other, the first end being rotatably disposed on the cover plate, and the second end being selectively abutting against the box body; wherein, the first end is provided with a plurality of slots, the plurality of slots being arranged sequentially along the rotation direction of the first end, and the tailgate assembly further includes a locking member, the locking member being selectively engaged with at least one slot to adjust the opening angle of the cover plate.

[0007] According to the tailgate assembly for vehicles provided in the first aspect of this application, when the locking member cooperates with the corresponding slot, a rigid lock can be achieved between the support and the cover. When the support rotates to a preset angle, the locking member selectively cooperates with different slots, which can lock the cover when the cover and the bottom wall of the box form different angles. Ultimately, it can achieve multi-level precise adjustment of the opening angle of the cover. Specifically, the arrangement of multiple slots along the rotation direction helps to adjust the opening angle of the cover in multiple levels. The arrangement trajectory of the multiple slots is consistent with the rotation trajectory of the support, which means that each slot corresponds to a specific rotation angle of the support, and thus corresponds to an opening angle between the cover and the box. This can meet the needs of different usage scenarios, making it convenient for users to adjust the appropriate angle as needed, and greatly improving the ease of use.

[0008] Optionally, the cover plate is provided with a mounting base, the first end of which is rotatably disposed on the mounting base. The mounting base is provided with a first hole, through which a locking member passes to selectively engage with at least one slot to adjust the opening angle of the cover plate.

[0009] In the above solution, on the one hand, a dedicated and suitable rotating mounting carrier can be provided for the first end of the support, avoiding damage to the strength of the cover plate caused by directly machining the rotating connection structure on the cover plate body. This can reduce the damage to the overall rigidity of the cover plate body caused by machining such as opening holes and welding. On the other hand, the first hole on the mounting base can provide precise installation and guiding constraints for the locking component, so that the locking component always moves along the preset path, such as the axis of the first hole, ensuring that it can accurately align with the slot at the first end of the support, avoiding fit failure or adjustment jamming caused by the offset of the locking component, improving the accuracy of angle adjustment and ease of operation. Users can complete the engagement without repeatedly adjusting the position of the locking component.

[0010] Optionally, the cover plate is also provided with a support seat, the support seat having a limiting opening, and along the rotation direction of the first end, the limiting opening having a first sidewall and a second sidewall disposed opposite to each other, the first end having a limiting protrusion disposed between the first sidewall and the second sidewall.

[0011] In the above scheme, on the one hand, the first sidewall and the second sidewall, which are arranged opposite to each other along the rotation direction of the first end, can abut against each other on both sides of the limiting protrusion to strictly limit the maximum and minimum rotation angles of the first end of the support part, so as to avoid the support part from completely misaligning the slot and the locking part due to overtravel of rotation, and reduce the probability of angle locking failure due to misalignment. On the other hand, the limiting protrusion is always located between the first sidewall and the second sidewall, which can form a lateral limit on the support part during rotation, reduce the probability of the support part shaking, ensure that the rotation trajectory of the first end of the support part is always stable, avoid the locking part and the slot from misalignment due to shaking, and further improve the accuracy of angle adjustment and the smoothness of operation.

[0012] Optionally, along the axial direction of the first end, the support is located between the first end and the mounting base, and the mounting base is fixed to the support.

[0013] In the above solution, it helps to optimize the precision of space and function matching. The support base, as an intermediate transition component, directly cooperates with the limiting protrusion at the first end of the support to achieve rotation limit, and can also be used to fix the mounting base to support the installation and guiding function of the locking component. This ensures that the support base and the mounting base that plays the role of locking are precisely aligned in the axial direction. When the first end of the support rotates, it reduces locking jamming or limit failure caused by axial misalignment of components, and further improves the smoothness and reliability of angle adjustment.

[0014] Optionally, the tailgate assembly also includes a protective shell, which covers a mounting base and a support base, and the protective shell has a second hole for the locking element to pass through.

[0015] In the above solution, the protective shell can isolate the mounting base, support base, and the connecting structure between them (such as fixing bolts and joint gaps) from the internal environment of the tail box, effectively preventing dust, rainwater, and debris (such as debris and liquid splashes) from entering the core functional components. It also prevents the first hole of the mounting base from being blocked, reduces the probability of affecting the sliding of the locking parts, and reduces the probability of wear on the limit opening of the support base leading to a decrease in limit accuracy. At the same time, it reduces the probability of metal parts rusting due to moisture, significantly extends the service life of the mounting base and support base, and ensures the long-term reliability of the angle adjustment and limit functions.

[0016] Optionally, along the axial direction of the first end, the projection of the first hole falls into the limiting opening.

[0017] In the above solution, on the one hand, it can ensure that after the locking member passes through the first hole, the end of it that is used to cooperate with the slot can accurately match the first end of the support part, reducing the positional deviation of the first hole that causes the locking member to face the invalid area outside the limiting opening (such as the part without the slot at the first end), which helps to reduce and avoid the problem of the locking member not being able to align with the slot after it is passed through, and significantly improves the accuracy and smoothness of the locking cooperation when adjusting the angle.

[0018] Optionally, the first end is further provided with a recessed portion, which extends along the rotation direction of the first end, and multiple slots are provided on the bottom wall of the recessed portion.

[0019] In the above scheme, the layout of the recess extending along the rotation direction allows multiple slots to be arranged in an orderly manner according to the rotation trajectory within the same regular area, avoiding the difficulty of aligning the locking parts due to the scattered placement of the slots. At the same time, the side wall of the recess can provide lateral guidance for the locking action of the locking parts, preventing the locking parts from shifting in a direction perpendicular to the bottom wall when they are engaged with the slots, ensuring that the locking parts are always accurately aligned with the slots, and greatly improving the smoothness of operation when adjusting the angle.

[0020] Optionally, the first hole extends through the outer periphery of the mounting base.

[0021] In the above solution, the first hole can limit the locking component, which can slide within the first hole. The first hole penetrates the outer periphery of the mounting base, which helps to reduce the volume of the mounting base, reduce the overall volume, reduce the space occupied, and improve the structural compactness. When locking the component, it is not necessary to strictly align it with a specific inner direction of the mounting base. The locking component can be directly inserted into the hole from the edge opening of the mounting base. Especially when the internal space is limited after the mounting base and the support base are fixed, it can greatly simplify the installation steps of the locking component, reduce the operational difficulty and positioning accuracy requirements during assembly, and improve the overall assembly efficiency.

[0022] Optionally, the locking element is constructed as a locking pin, and one end of the locking pin is provided with a locking tooth that mates with a slot along the axial direction of the locking pin.

[0023] In the above solution, the rigid rod-shaped structure of the locking pin is less prone to deformation due to long-term use or stress compared to locking methods such as elastic buckles. It can stably maintain the matching accuracy with the slot. Compared to the surface contact between the smooth locking end and the slot, the meshing of the locking teeth and the slot can increase the contact area and biting friction, effectively preventing the locking pin and the slot from sliding relative to each other when the vehicle is vibrating or the cover is slightly stressed. This completely avoids accidental deviation of the cover opening angle and greatly improves the locking stability.

[0024] Secondly, embodiments of this application provide a vehicle including the tailgate assembly described in any of the embodiments.

[0025] The vehicle proposed according to the second aspect of this application has improved ease of use due to the tailgate assembly described in the above embodiments. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0048] As people's car usage scenarios become increasingly diverse, their demands for self-driving camping, in-car rest, and in-car entertainment are becoming more prominent, and the car trunk plays an important role in these scenarios. The car trunk has evolved from a storage space into a multifunctional living space, with the trunk cover enhancing its functionality and practicality by adding components.

[0049] Some car trunk lids have an adjustable angle, but the implementation and effect vary: traditional trunk lids can be flipped upwards to retrieve items from the trunk pit, at which time the lid needs to be held by hand; some trunk lids also have a slot on the bottom, which can be inserted to fix the lid after it is flipped.

[0050] In traditional car camping scenarios, the trunk lid is typically used as a base to create a bed with the seatbacks. However, this only accommodates the single, pre-set scenario of "bed-up rest," and users can only lie flat inside the car. If they want to recline, there's no support for their back and head, making it impossible. People of different heights have different reclining angles, and if the trunk lid can only tilt at a fixed angle, it cannot accommodate different reclining preferences, resulting in poor reclining comfort and ergonomic issues. Adding reclining accessories to the trunk not only takes up trunk storage space and increases costs, but also prevents quick switching between "bed-up mode" and "reclining mode."

[0051] In related technologies, most traditional car trunk covers are laid flat inside the trunk. Some can be adjusted in height, but not in angle, which is inconvenient to use. Therefore, how to improve the ease of use of trunk covers is a technical problem that urgently needs to be solved.

[0052] In view of this, in order to improve the ease of use of the tailgate assembly, this application proposes a tailgate assembly for automobiles. The first end 310 of the support 300 is provided with multiple slots 311, which are arranged sequentially along the rotation direction of the first end 310. The tailgate assembly also includes a locking member 400, which can selectively cooperate with at least one slot 311 to adjust the opening angle of the cover 200. It can be understood that when the locking member 400 cooperates with the corresponding slot 311, it can achieve rigid locking between the support 300 and the cover 200. When the support 300 rotates to a preset angle, the locking member 400 selectively cooperates with different slots 311, which can lock the cover 200 when the cover 200 forms different angles with the bottom wall of the box body 100. Finally, it can achieve multi-level precise adjustment of the opening angle of the cover 200, improve the functional diversity and applicability of the cover 200, and improve the ease of use.

[0053] The following description, in conjunction with the accompanying drawings, describes a tailgate assembly for a vehicle according to an embodiment of this application.

[0054] Please refer to Figures 1-2 According to an embodiment of this application, a tailgate assembly for a vehicle includes a body 100, a cover 200, and a support 300.

[0055] The box 100 has a pit 100a, the upper end of which is open to form an opening 100b; it is understood that the pit 100a can form an independent storage space for storing items.

[0056] The cover 200 is rotatably mounted on the body 100 to open or close the opening 100b. Understandably, the cover 200 can close the pit 100a. On the one hand, it can make the pit 100a an independent space for storing items, which can protect the items inside the pit 100a. It can block external dust and rainwater from entering the pit 100a, preventing the items from getting damp or dirty. It can also prevent items from falling out of the opening 100b due to bumps while the vehicle is in motion, thus taking into account both practicality and safety. On the other hand, it can ensure that the inside of the trunk is flat, reducing the space occupied.

[0057] Along the length of the support portion 300, the support portion 300 has a first end 310 and a second end 320 disposed opposite to each other. The first end 310 is rotatably disposed on the cover plate 200, and the second end 320 can selectively abut against the box body 100. It can be understood that the support portion 300 can support the cover plate 200. When the cover plate 200 is closed, the support portion 300 can be retracted with the cover plate 200 and fit against the inner side of the cover plate 200 without occupying the storage space of the sink 100a. When the cover plate 200 is open, the second end 320 can select a suitable abutment point to contact the box body 100 according to the opening angle of the cover plate 200, providing stable support for the cover plate 200 and preventing the cover plate 200 from falling automatically due to its own weight. Users do not need to hold the cover plate 200 when loading and unloading items, improving the safety and convenience of operation.

[0058] Please refer to Figure 3 and Figure 4 The first end 310 is provided with a plurality of slots 311, which are arranged sequentially along the rotation direction of the first end 310. The tail box assembly also includes a locking member 400, which can selectively cooperate with at least one slot 311 to adjust the opening angle of the cover 200.

[0059] Understandably, the arrangement of multiple slots 311 along the rotation direction facilitates multi-position adjustment of the opening angle of the cover 200. The arrangement trajectory of the multiple slots 311 is consistent with the rotation trajectory of the support 300, meaning that each slot 311 corresponds to a specific rotation angle of the support 300, and thus corresponds to an opening angle between the cover 200 and the box 100. This can meet the needs of different usage scenarios, allowing users to adjust the appropriate angle as needed, greatly improving ease of use. For example, shorter users can choose a smaller opening angle for easier closing; a larger opening angle can be chosen when loading and unloading large items to expand the operating space; and a medium angle can be chosen when opening in rainy weather to reduce rainwater entering the sink 100a.

[0060] Furthermore, the locking element 400 and the slot 311 achieve angle locking through rigid engagement. Compared with traditional gas spring supports, this reduces the decrease in support force and angle shift caused by air leakage, and also reduces the chance of loosening due to vibration. The engagement of the locking element 400 and the slot 311 can firmly fix the position of the support part 300, ensuring that the cover 200 will not shake or fall accidentally after opening, thus improving reliability. At the same time, the adjustment operation is simple. Users only need to rotate the cover 200 to the target angle so that the locking element 400 can be engaged in the corresponding slot 311 to complete the locking, without the need for tools, further improving the convenience of use.

[0061] At the same time, when the cover plate 200 closes the opening 100b, it can also be locked by the locking member 400 cooperating with the slot 311. At this time, the support part 300 can be stored at the bottom of the cover plate 200 to reduce the space occupied.

[0062] In other embodiments, please refer to Figure 1 , Figure 4 and Figure 5 The cover plate 200 is provided with a mounting base 210, and the first end 310 is rotatably disposed on the mounting base 210. The mounting base 210 is provided with a first hole 211, and the locking member 400 passes through the first hole 211 to selectively cooperate with at least one slot 311 to adjust the opening angle of the cover plate 200.

[0063] In the above solution, on the one hand, a dedicated and suitable rotating mounting carrier can be provided for the first end 310 of the support 300, avoiding damage to the strength of the cover plate 200 caused by directly machining the rotating connection structure on the cover plate 200 body. This can reduce the damage to the overall rigidity of the cover plate 200 body caused by machining such as opening holes and welding. On the other hand, the first hole 211 on the mounting base 210 can provide precise installation and guiding constraints for the locking member 400, so that the locking member 400 always moves along the preset path, such as the axial direction of the first hole 211, ensuring that it can be accurately aligned with the slot 311 of the first end 310 of the support 300. This avoids the failure of fit or adjustment jamming caused by the offset of the locking member 400, improves the accuracy of angle adjustment and the convenience of operation, and allows the user to complete the engagement without repeatedly adjusting the position of the locking member 400.

[0064] Furthermore, the structure of the locking member 400 passing through the first hole 211 can enhance the locking reliability after it is engaged with the slot 311. The first hole 211 can limit the radial sway of the locking member 400, reduce the risk of the locking member 400 disengaging from the slot 311 when the vehicle is vibrating or the cover plate 200 is slightly stressed, and further ensure the stability of the opening angle of the cover plate 200. At the same time, the mounting base 210 is an independent functional component. If wear or failure occurs in the future, only the mounting base 210 needs to be replaced, without the need to repair or replace the entire cover plate 200, thus reducing maintenance costs and difficulty.

[0065] In other embodiments, please refer to Figure 1 , Figure 4 and Figure 5 The cover plate 200 is also provided with a support base 220, which has a limiting opening 221. Along the rotation direction of the first end 310, the limiting opening 221 has a first sidewall 221a and a second sidewall that are disposed opposite each other. The first end 310 has a limiting protrusion 312, which is disposed between the first sidewall 221a and the second sidewall. It can be understood that the limiting opening 221 can provide reliable stroke constraint and directional guidance for the rotation of the support part 300.

[0066] In the above scheme, on the one hand, the first sidewall 221a and the second sidewall, which are arranged opposite to each other along the rotation direction of the first end 310, can abut against the two sides of the limiting protrusion 312, strictly limiting the maximum and minimum rotation angles of the first end 310 of the support part 300, avoiding the complete misalignment of the slot 311 and the locking member 400 due to the overtravel of the support part 300, reducing the probability of angle locking not being achieved due to misalignment, and at the same time reducing the probability of hard collision with other components in the tail box (such as the sidewall of the box 100 and the edge of the pit 100a) due to excessive rotation, reducing the wear or even damage of the support part 300, the slot 311 or other components.

[0067] On the other hand, the limiting protrusion 312 is always located between the first side wall 221a and the second side wall, which can form a lateral limit on the support part 300 during rotation, reduce the probability of the support part 300 shaking, ensure that the rotation trajectory of the first end 310 of the support part 300 is always stable, avoid the misalignment of the locking part 400 and the slot 311 due to shaking, and further improve the accuracy of angle adjustment and the smoothness of operation.

[0068] Meanwhile, this mechanical limiting structure does not require additional electrical control or elastic components. It can achieve its function through rigid engagement only. The structure is simple and reliable with a low failure rate. When the user rotates the support part 300, the limiting protrusion 312 will produce obvious limiting feedback when it touches the first side wall 221a or the second side wall. The user can know that the support part 300 has been rotated to the limit position without relying on visual judgment, avoiding blind operation and significantly improving the convenience and safety of use.

[0069] In other embodiments, please refer to Figure 1 , Figure 4 and Figure 5 Along the axial direction of the first end 310, the support base 220 is located between the first end 310 and the mounting base 210, with the mounting base 210 fixed to the support base 220. This arrangement helps optimize the precision of spatial and functional alignment. The support base 220, as an intermediate transition component, directly engages with the limiting protrusion 312 of the first end 310 of the support part 300 to achieve rotational limitation, and can also be used to fix the mounting base 210 to support the installation and guiding function of the locking member 400. This ensures that the support base 220 and the mounting base 210, which plays a locking role, are precisely aligned in the axial direction. When the first end 310 of the support part 300 rotates, it reduces locking jamming or limitation failure caused by axial misalignment of components, further improving the smoothness and reliability of angle adjustment.

[0070] At the same time, it helps to strengthen the overall structural rigidity. The mounting base 210 and the support base 220 are fixed as one piece, rather than being fixed independently to the cover plate 200. This reduces the installation point requirements of the cover plate 200 body, avoids weakening the strength of the cover plate 200 due to too many openings, and facilitates the dispersion of the force generated when the support part 300 rotates, reducing the stress deformation of individual components and extending the service life of core components.

[0071] Furthermore, it helps simplify the assembly and maintenance process. During assembly, the support base 220 and the mounting base 210 can be pre-assembled outside the cover plate 200, such as by bolting and welding, and then the entire module can be installed on the cover plate 200, reducing on-site assembly steps and improving efficiency. If a component needs to be repaired later, it can be disassembled as a whole. For example, if the first hole 211 of the mounting base 210 is worn or the limiting sidewall of the support base 220 is deformed, there is no need to separate the two components. This modular design improves ease of use and reduces maintenance difficulty and cost.

[0072] In other embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The tailgate assembly also includes a protective shell 500, which covers the mounting base 210 and the support base 220. The protective shell 500 has a second hole 510 through which the locking member 400 passes. Understandably, the protective shell 500 serves to protect the mounting base 210 and the support base 220.

[0073] In the above solution, the protective shell 500 can isolate the mounting base 210, the support base 220 and the connecting structure between them (such as fixing bolts and connecting gaps) from the internal environment of the tail box, effectively preventing dust, rainwater and debris (such as debris and liquid splashes) from entering the core functional components, avoiding the first hole 211 of the mounting base 210 from being blocked, reducing the probability of affecting the sliding of the locking part 400 and the wear of the limiting opening 221 of the support base 220 leading to a decrease in limiting accuracy, while reducing the probability of metal parts rusting due to moisture, significantly extending the service life of the mounting base 210 and the support base 220, and ensuring the long-term reliability of the angle adjustment and limiting functions.

[0074] On the other hand, the protective case 500 can integrate the scattered mounting bases 210 and support bases 220 into a functional module with a neat appearance, concealing the complex internal connection structure and component gaps, preventing clothing from getting caught on the edges of the mounting base 210, the protrusions of the support base 220, or the connectors when users take or put in items, while improving the visual cleanliness of the trunk interior and optimizing the user experience.

[0075] Furthermore, the second hole 510 on the protective shell 500 and the first hole 211 of the mounting base 210 form a coaxial guide, which can provide secondary constraint on the movement path of the locking member 400, further reducing the radial offset of the locking member 400 during the insertion process, ensuring that it is accurately aligned with the slot 311 of the first end 310 of the support part 300, avoiding jamming caused by the skewness of the locking member 400. At the same time, the second hole 510 can also protect the exposed part of the locking member 400, preventing external collisions from deforming or damaging the locking member 400, further enhancing the stability and safety of the overall structure.

[0076] In other embodiments, the projection of the first hole 211 along the axial direction of the first end 310 falls into the limiting opening 221. This arrangement ensures that after the locking member 400 passes through the first hole 211, the end that engages with the slot 311 can accurately match the first end 310 of the support 300. This reduces the possibility of the locking member 400 facing an invalid area outside the limiting opening 221 (such as the part of the first end 310 without the slot 311) due to the positional deviation of the first hole 211. It also helps to reduce and avoid the problem of the locking member 400 not being able to align with the slot 311 after it is inserted, and significantly improves the accuracy and smoothness of the locking engagement during angle adjustment.

[0077] On the other hand, when the first end 310 of the support part 300 rotates under the constraint of the limiting opening 221, the movement trajectory of the slot 311 is always within the reach of the locking member 400. The user can complete the locking without repeatedly adjusting the position of the support part 300, reducing the cost of trial and error and improving the user experience.

[0078] In other embodiments, please refer to Figure 1 , Figure 4 and Figure 5 The first end 310 is also provided with a recess 313, which extends along the rotation direction of the first end 310, and a plurality of slots 311 are provided on the bottom wall of the recess 313.

[0079] In the above scheme, the layout of the recessed portion 313 extending along the rotation direction allows multiple slots 311 to be arranged in an orderly manner according to the rotation trajectory within the same regular area, avoiding the difficulty in aligning the locking member 400 due to the scattered arrangement of the slots 311. At the same time, the side wall of the recessed portion 313 can provide lateral guidance for the locking member 400's engagement action, preventing the locking member 400 from shifting in a direction perpendicular to the bottom wall when engaging with the slot 311, ensuring that the locking member 400 is always accurately aligned with the slot 311, and greatly improving the smoothness of operation during angle adjustment.

[0080] On the other hand, the recess 313 can provide physical protection for the slot 311, preventing dust and small debris (such as paper scraps and debris) in the trunk from accumulating directly in the slot 311 on the bottom wall of the recess 313. This can effectively prevent the slot 311 from being blocked, thus preventing the locking part 400 from engaging properly, reducing the frequency of cleaning and maintenance of the slot 311, and extending its functional lifespan.

[0081] In other embodiments, the first hole 211 extends through the outer periphery of the mounting base 210.

[0082] In the above scheme, the first hole 211 can limit the locking member 400. The locking member 400 can slide in the first hole 211. The first hole 211 penetrates the outer periphery of the mounting base 210, which helps to reduce the volume of the mounting base 210, reduce the overall volume, reduce the space occupied, and improve the structural compactness.

[0083] During assembly, the locking component 400 does not need to be strictly aligned with the specific inner direction of the mounting base 210. The locking component 400 can be directly inserted into the hole from the edge opening of the mounting base 210. Especially when the internal space is limited after the mounting base 210 and the support base 220 are fixed, the installation steps of the locking component 400 can be greatly simplified, the operation difficulty and positioning accuracy requirements during assembly can be reduced, and the overall assembly efficiency can be improved.

[0084] On the other hand, the hole that runs through the outer perimeter does not require blind holes to be machined inside the mounting base 210, reducing problems such as poor chip removal and insufficient bottom precision caused by blind hole machining. It can be directly formed from the edge through conventional processes such as milling and drilling, which not only reduces the requirements of processing equipment and production costs, but also reduces burrs and errors on the inner wall of the hole, ensuring the smoothness of the sliding of the locking part 400.

[0085] In other embodiments, the locking member 400 is constructed as a locking pin, and one end of the locking pin is provided with a locking tooth 410 that engages with the locking groove 311 along the axial direction of the locking pin.

[0086] In the above solution, the rigid rod-shaped structure of the locking pin is less prone to deformation due to long-term use or stress compared to locking forms such as elastic buckles. It can stably maintain the matching accuracy with the slot 311. Compared to the surface contact between the smooth locking end and the slot 311, the meshing of the locking teeth 410 and the slot 311 can increase the contact area and biting friction, effectively preventing the locking pin and the slot 311 from sliding relative to each other when the vehicle is vibrating or the cover plate 200 is slightly stressed. This completely avoids the unexpected deviation of the opening angle of the cover plate 200 and greatly improves the locking stability.

[0087] On the other hand, the tooth 410, which is arranged along the axial direction of the locking pin, can be precisely matched with the groove shape of the slot 311 (such as rectangular teeth or trapezoidal teeth), so that when the locking pin is inserted into the slot 311, it can be quickly aligned by the guide of the tooth groove, reducing jamming and avoiding the cover plate 200 from loosening due to incomplete locking, which significantly improves the convenience and safety of operation.

[0088] In a specific embodiment, the support part 300 includes a rod body, which includes a first telescopic rod, a support rod, and a second telescopic rod. One end of the first telescopic rod is provided with a first end 310, and the other end of the first telescopic rod is constructed as a second end 320 and connected to one end of the support rod. One end of the second telescopic rod is also provided with a first end 310, and the other end of the second telescopic rod is also constructed as a second end 320 and connected to the other end of the support rod.

[0089] The first telescopic rod and the second telescopic rod have the same structure and both include a first rod part and a second rod part. The first rod part is sleeved on the second rod part and is rotatably mounted on the cover plate 200. One end of the second rod part is located inside the first rod part, and the other end of the second rod part is connected to the support rod.

[0090] The support rod includes a first section, a second section, and a third section. One end of the second section is connected to one end of the first section, the other end of the second section is connected to one end of the third section, the other end of the first section is connected to the first telescopic rod, and the other end of the third section is connected to the second telescopic rod.

[0091] The axis of the second section extends in the left-right direction of the vehicle, and at least one of the first and third sections is constructed in an arc shape.

[0092] With this design, when the opening angle of the cover 200 changes, the telescopic length of the support 300 can be changed, thereby abutting the support rod against the inner wall of the box 100 to support the cover 200, further improving ease of use.

[0093] Secondly, embodiments of this application provide a vehicle including the tailgate assembly described in any of the embodiments.
