Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a tailgate limiting component and a vehicle. Background Technology

[0002] With the development of vehicle technology, users have placed higher demands on the performance of vehicles in all aspects. Among these demands is the tailgate, used for carrying and storing goods. During vehicle operation, especially on rough roads, the tailgate is prone to relative displacement with the vehicle body, leading to abnormal noises and even damage from impacts. To improve vehicle driving quality and safety, tailgate limiting components are needed to constrain the relative movement of the tailgate and the vehicle body.

[0003] In related technologies, a tailgate limiting component includes a body limiting member and a tailgate limiting member. The body limiting member includes a body mounting portion and a body limiting portion; the body mounting portion is mounted on the vehicle body, and the body limiting portion is disposed on the body mounting portion. The tailgate limiting member includes a tailgate mounting portion and a tailgate limiting portion; the tailgate mounting portion is mounted on the tailgate, and the tailgate limiting portion is disposed on the tailgate mounting portion. One of the body limiting portion and the tailgate limiting portion is a limiting protrusion, and the other is a limiting groove; the limiting protrusion and the limiting groove are interference-fitted.

[0004] However, the aforementioned technologies have some drawbacks. Specifically, the dimensional accuracy of the limiting concave and convex structures of the body limiting part and the tailgate limiting part is extremely high. This means that during vehicle assembly, the body limiting parts and the tailgate limiting parts need to be repeatedly aligned and tested. Consequently, the installation positions of the body limiting parts and the body or the tailgate limiting parts and the tailgate need to be adjusted, resulting in low vehicle production efficiency. Utility Model Content

[0005] This utility model provides a tailgate limiting component and a vehicle to solve the problem in related technologies that require repeated alignment tests on the body limiting component and the tailgate limiting component, which necessitates adjusting the installation position of the body limiting component and the body or the tailgate limiting component and the tailgate, resulting in low vehicle production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] On one hand, a tailgate limiting assembly is provided, including a vehicle body limiting member and a tailgate limiting member. The vehicle body limiting member includes a first mounting portion and a first limiting portion, the first mounting portion being connected to the first limiting portion and used for fixed connection with the vehicle body. The tailgate limiting member includes a second mounting portion and a second limiting portion, the second mounting portion being used for fixed connection with the tailgate. The second mounting portion is located on the side of the second limiting portion away from the vehicle body limiting member, the second limiting portion is connected to the second mounting portion, and is movable relative to the second mounting portion in a first direction. The second limiting portion engages with the first limiting portion.

[0008] In some embodiments, the second mounting portion is provided with a guide groove, which is located on the side of the second mounting portion near the second limiting portion and extends along the first direction. The second limiting portion is provided with a guide protrusion, which is located on the side of the second limiting portion near the second mounting portion. The guide protrusion is located within the guide groove and can slide along the guide groove.

[0009] In some embodiments, the tailgate limiting assembly further includes an adjusting member comprising a head and a body. The second limiting portion has a first limiting groove with an adjusting hole extending along a first direction. The body passes through the adjusting hole, and the second limiting portion is movable relative to the adjusting member along the first direction. The second mounting portion has a through hole. The body portion passes sequentially through the adjusting hole and the through hole to clamp the second limiting portion between the head and the second mounting portion. The head abuts against the bottom wall of the first limiting groove and does not extend beyond the surface of the second limiting portion adjacent to the first limiting portion.

[0010] In some embodiments, the first limiting portion has a second groove on the side near the second limiting portion, and the second groove extends through the edge of one side of the first limiting portion along a second direction. The second limiting portion is at least partially located within the second groove and contacts the sidewall of the second groove. In the cross-section of the second groove, the side length near the second limiting portion is greater than the side length away from the second limiting portion. The second direction is parallel to the plane containing the surface of the second mounting portion near the second limiting portion and perpendicular to the first direction.

[0011] In some embodiments, the surface of the second mounting portion near the second limiting portion is provided with a first concave-convex structure, and the surface of the second limiting portion near the second mounting portion is provided with a second concave-convex structure, wherein the first concave-convex structure and the second concave-convex structure abut against each other.

[0012] In some embodiments, the second limiting portion further comprises a first opening and a second opening that communicate with each other. The second limiting portion includes adjacent first surfaces, second surfaces, and third surfaces. The first opening extends through at least a portion of the second limiting portion along the first direction via the first surface, and also extends through at least a portion of the second limiting portion along the second direction via the second surface. The second opening extends through at least a portion of the second limiting portion along the second direction via the second surface, and also extends through at least a portion of the second limiting portion along the third direction via the third surface. The second direction is parallel to the plane containing the surface of the second mounting portion near the second limiting portion, and perpendicular to the first direction; the third direction is perpendicular to both the first direction and the second direction.

[0013] In some embodiments, the tailgate limiting assembly further includes a buffer block, and the second limiting portion is further provided with a buffer groove. The second limiting portion further includes a fourth surface, which is disposed opposite to the third surface. The buffer groove is disposed on the fourth surface. The first opening and the second opening penetrate the second limiting portion and communicate with the buffer groove. The buffer block is disposed in the buffer groove.

[0014] In some embodiments, the tailgate limiting assembly further includes a first fastener and a second fastener, and the second mounting portion is further provided with a first mounting hole and a second mounting hole. The first fastener is located within the first mounting hole, and one end of the first fastener near the second limiting portion does not extend beyond the surface of the second mounting portion near the second limiting portion. The second fastener is located within the second mounting hole, and one end of the second fastener near the second limiting portion does not extend beyond the surface of the second mounting portion near the second limiting portion.

[0015] In some embodiments, the tailgate limiting assembly further includes a third fastener and a fourth fastener. The first mounting portion also has a third mounting hole and a fourth mounting hole, the fourth mounting hole extending along the first direction, and the third mounting hole located in the extending direction of the fourth mounting hole. The third fastener is located within the third mounting hole; the fourth fastener is located within the fourth mounting hole, and the first mounting portion is movable relative to the fourth fastener along the first direction.

[0016] On the other hand, a vehicle is provided, comprising a tailgate limiting assembly, a vehicle body, and a tailgate as described in the above embodiments. A first mounting portion is fixedly connected to the vehicle body, the tailgate is fixedly connected to the vehicle body, and a second mounting portion is fixedly connected to the tailgate. The tailgate is rotatable relative to the vehicle body along a first axis; and in a first position, the second limiting portion engages with the first limiting portion; in a second position, the second limiting portion disengages from the first limiting portion; the first axis extends along a first direction.

[0017] Therefore, the above-mentioned technical features of this utility model have the following beneficial effects:

[0018] (1) During the vehicle assembly process, when the second limiting part and the first limiting part are not aligned and engaged, the second limiting part can be moved relative to the second mounting part along the first direction Z to adjust the relative position of the second limiting part and the second mounting part, so as to achieve alignment and engagement of the second limiting part and the first limiting part. There is no need to adjust the installation position of the body limiting part and the body or the installation position of the tailgate limiting part and the tailgate, thereby improving the production efficiency of the vehicle.

[0019] (2) The guide protrusion and guide groove provide guidance for the second limiting part and the second mounting part to move relative to each other in the first direction.

[0020] (3) During vehicle assembly, the adjusting component can be passed through the adjusting hole and the through hole in sequence to pre-install the second mounting part and the second limiting part. The pre-installation torque is less than or equal to 0.5 N·m. When the second limiting part and the first limiting part are not aligned and engaged, the second limiting part can be moved relative to the adjusting component along the first direction to adjust the relative position of the second limiting part and the second mounting part, thereby achieving alignment and engagement between the second limiting part and the first limiting part. Furthermore, since the head does not exceed the surface of the second limiting part near the first limiting part, the adjusting component will not interfere with the movement of the second limiting part, ensuring the smooth completion of the adjustment process of the relative movement of the second limiting part and the second mounting part along the first direction.

[0021] (4) The second limiting part can penetrate the edge of the first limiting part along the second direction along the second groove to achieve a snap-fit ​​engagement with the second groove. Furthermore, during vehicle assembly, the first limiting part and the second limiting part can be automatically aligned and snapped together by repeatedly opening and closing the tailgate. That is, when the tailgate is closed, because the first limiting part and the second limiting part are not aligned, the second limiting part will abut against the sloping sidewall of the second groove, causing interference. Due to the interference force, the second limiting part will move towards the non-interference end, thereby achieving automatic snap-fit ​​engagement between the first limiting part and the second limiting part.

[0022] (5) When the second limiting part is aligned and engaged with the first limiting part, the second limiting part and the second mounting part stop moving due to the frictional resistance generated by the first concave and convex structure and the second concave and convex structure. This prevents the second limiting part and the second mounting part from moving too much relative to each other due to inertia, reduces the number of times the tailgate is opened and closed during the assembly process, and further improves the production efficiency of the vehicle.

[0023] (6) When the tailgate is opened, the second limiting part needs to be separated from the first limiting part. In order to prevent the interference fit between the second limiting part and the first limiting part from being too large, which would make it difficult for the second limiting part to separate from the second groove, the second limiting part is provided with a first opening and a second opening, so that the second limiting part can undergo slight deformation and the tailgate can be opened easily.

[0024] (7) During the process of opening the rear door, the second limiting part located at the first opening and the second opening will deform. The buffer block can fill part of the first opening and the second opening, support the second limiting part, and prevent the second limiting part located at the first opening and the second opening from being damaged due to excessive deformation.

[0025] (8) The first fastener and the second fastener achieve a fixed connection between the second mounting part and the rear door, and the end of the first fastener near the second limiting part does not exceed the surface of the second mounting part near the second limiting part, and the end of the second fastener near the second limiting part does not exceed the surface of the second mounting part near the second limiting part, so that the first fastener and the second fastener will not interfere with the movement of the second limiting part, and ensure the smooth completion of the adjustment process of the relative movement of the second limiting part and the second mounting part along the first direction.

[0026] (9) Since the third mounting hole is located in the extension direction of the fourth mounting hole, the fourth mounting hole can absorb the tolerance during the assembly process, that is, the position of the first mounting part installed on the vehicle body can be adjusted, thereby improving the assembly efficiency.

Detailed Implementation

[0042] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, this application embodiment provides a vehicle 1000, which can be any power-driven vehicle such as a fuel vehicle or a new energy vehicle. The vehicle 1000 includes a tailgate limiting assembly 100, a body 200, and a tailgate 300. The tailgate 300 is fixedly connected to the body 200 and can rotate relative to the body 200 along a first axis, which extends along a first direction Z.

[0044] For example, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the tailgate limiting assembly 100 includes a body limiting member 10 and a tailgate limiting member 20. The body limiting member 10 includes a first mounting portion 11 and a first limiting portion 12. The tailgate limiting member 20 includes a second mounting portion 21 and a second limiting portion 22. The first mounting portion 11 is fixedly connected to the body 200, and the second mounting portion 21 is fixedly connected to the tailgate 300. In a first position, the second limiting portion 22 is engaged with the first limiting portion 12. In a second position, the second limiting portion 22 is separated from the first limiting portion 12. The second limiting part 22 and the first limiting part 12 are interference-fitted to limit the relative displacement of the body limiting part 10 and the tailgate limiting part 20 in the first direction Z, and to increase the fit between the body limiting part 10 and the tailgate limiting part 20 in the second direction X and the third direction Y. This can effectively improve the connection stability between the body 200 and the tailgate 300 and avoid the problem of abnormal noise caused by the collision between the tailgate 300 and the body 200.

[0045] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the first mounting part 11 is connected to the first limiting part 12, and the second mounting part 21 is located on the side of the second limiting part 22 away from the vehicle body limiting member 10. The second limiting part 22 is connected to the second mounting part 21 and can move relative to the second mounting part 21 in the first direction Z. The second limiting part 22 is engaged with the first limiting part 12.

[0046] In this case, during the assembly process of vehicle 1000, when the second limiting part 22 and the first limiting part 12 are not aligned and engaged, the second limiting part 22 can be moved relative to the second mounting part 21 along the first direction Z, thereby adjusting the relative position of the second limiting part 22 and the second mounting part 21, so as to achieve alignment and engagement between the second limiting part 22 and the first limiting part 12. There is no need to adjust the installation position of the body limiting part 10 and the body 200 or the installation position of the tailgate limiting part 20 and the tailgate 300, thereby improving the production efficiency of the vehicle.

[0047] It should be noted that after repeatedly opening and closing the tailgate 300 to achieve the alignment and engagement of the second limiting part 22 and the first limiting part 12, the second limiting part 22 and the second mounting part 21 are fixed to complete the assembly of the tailgate limiting assembly 100.

[0048] For example, the first mounting portion 11 and the first limiting portion 12 of the vehicle body limiting member 10 are integrally formed, facilitating the overall installation and setting of the vehicle body limiting member 10. The first mounting portion 11 is used to mount on the vehicle body 200, and the first limiting portion 12 is used to suppress relative displacement between the tailgate 300 and the vehicle body. In this way, the integrally formed vehicle body limiting member 10 can strengthen the suppression of relative displacement between the tailgate 300 and the vehicle body 200. Furthermore, integral forming can improve the production efficiency of the vehicle body limiting member 10 and reduce production costs.

[0049] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the second mounting portion 21 is provided with a guide groove 211, which is located on the side of the second mounting portion 21 near the second limiting portion 22 and extends along the first direction Z. The second limiting portion 22 is provided with a guide protrusion 221, which is located on the side of the second limiting portion 22 near the second mounting portion 21. The guide protrusion 221 is located within the guide groove 211 and can slide along the guide groove 211. At this time, the guide protrusion 221 and the guide groove 211 provide a guiding function for the relative movement of the second limiting portion 22 and the second mounting portion 21 along the first direction Z.

[0050] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 and Figure 11As shown, the tailgate limiting assembly 100 also includes an adjusting member 30, which includes a head 31 and a main body 32. The second limiting part 22 has a first limiting groove 222, which has an adjusting hole 2221 extending along a first direction Z. The main body 32 passes through the adjusting hole 2221, and the second limiting part 22 is movable relative to the adjusting member 30 along the first direction Z. The second mounting part 21 has a through hole 212, and the main body 32 passes through the adjusting hole 2221 and the through hole 212 in sequence to clamp the second limiting part 22 between the head 31 and the second mounting part 21. The head 31 abuts against the bottom wall of the first limiting groove 222 and does not extend beyond the surface of the second limiting part 22 near the first limiting part 12.

[0051] During the assembly of vehicle 1000, the adjusting member 30 can be passed sequentially through the adjusting hole 2221 and the through hole 212 to pre-install the second mounting part 21 and the second limiting part 22. The pre-installation torque is less than or equal to 0.5 N·m. When the second limiting part 22 is not aligned and engaged with the first limiting part 12, the second limiting part 22 can be moved relative to the adjusting member 30 along the first direction Z to adjust the relative position of the second limiting part 22 and the second mounting part 21, thereby achieving alignment and engagement between the second limiting part 22 and the first limiting part 12. Furthermore, since the head 31 does not exceed the surface of the second limiting part 22 near the first limiting part 12, the adjusting member 30 will not interfere with the movement of the second limiting part 22, ensuring the smooth completion of the adjustment process of the relative movement of the second limiting part 22 and the second mounting part 21 along the first direction Z.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, a second groove 121 is provided on the side of the first limiting part 12 near the second limiting part 22, and the second groove 121 penetrates the edge of one side of the first limiting part 12 along the second direction X. The second limiting part 22 is at least partially located within the second groove 121 and contacts the side wall of the second groove 121. The second direction X is parallel to the plane containing the surface of the second mounting part 21 near the second limiting part 22 and perpendicular to the first direction Z. In this case, the second limiting part 22 can penetrate the second groove 121 along a portion of the edge of the first limiting part 12 along the second direction X, achieving a snap-fit ​​engagement with the second groove 121.

[0053] For example, such as Figure 3 and Figure 4As shown, the shapes of the second groove 121 and the second limiting part 22 include either a wedge shape or a trapezoidal shape. For example, the second groove 121 and the second limiting part 22 are trapezoidal. It can be understood that both the trapezoidal groove and the trapezoidal protrusion are provided with multiple contact surfaces in different directions. Thus, when the second limiting part 22 and the second groove 121 are engaged, there is an interference fit between the multiple contact surfaces in different directions, which can further improve the fit between the first limiting part 12 and the second limiting part 22.

[0054] For example, such as Figure 1 , Figure 3 and Figure 10 As shown, in the cross-section of the second groove 121, the side length of the side closer to the second limiting part 22 is greater than the side length of the side farther from the second limiting part 22. The cross-section is the cross-section of the second groove 121 in the plane perpendicular to the side of the first limiting part 12 away from the second limiting part 22. At this time, during the assembly process of the vehicle 1000, the first limiting part 12 and the second limiting part 22 can be automatically aligned and engaged by repeatedly opening and closing the tailgate 300. That is, when the tailgate 300 is closed, since the first limiting part 12 and the second limiting part 22 are not aligned, the second limiting part 22 will abut against the sloping sidewall of the second groove 121, causing interference. Due to the interference force, the second limiting part 22 will move towards the end without interference, thereby achieving automatic engagement between the first limiting part 12 and the second limiting part 22.

[0055] For example, the cross-sectional shape of the two grooves 121 includes a trapezoidal shape.

[0056] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, the surface of the second mounting part 21 near the second limiting part 22 is provided with a first concave-convex structure 213, and the surface of the second limiting part 22 near the second mounting part 21 is provided with a second concave-convex structure 223. The first concave-convex structure 213 and the second concave-convex structure 223 abut against each other. Based on the above configuration, when the second limiting part 22 is aligned and engaged with the first limiting part 12, the second limiting part 22 and the second mounting part 21 stop moving due to the frictional resistance generated by the first concave-convex structure 213 and the second concave-convex structure 223. This prevents excessive relative movement between the second limiting part 22 and the second mounting part 21 due to inertia, reduces the number of times the tailgate 300 is opened and closed during the assembly process, and further improves the production efficiency of the vehicle 1000.

[0057] For example, along the second direction Y, the cross-sectional shape of the first concave-convex structure 213 and / or the second concave-convex structure 223 includes either a wavy shape or a serrated shape. For instance, the cross-sectional shape of the first concave-convex structure 213 and / or the second concave-convex structure 223 is wavy.

[0058] In some embodiments, such as Figure 4 and Figure 7 As shown, the second limiting portion 22 also has a first opening 224 and a second opening 225 that are connected to each other. The second limiting portion 22 includes an adjacent first surface 22a, a second surface 22b, and a third surface 22c. The first opening 224 extends through at least a portion of the second limiting portion 22 along the first direction Z, through the first surface 22a, and through at least a portion of the second limiting portion 22 along the second direction X, through the second surface 22b. The second opening 225 extends through at least a portion of the second limiting portion 22 along the second direction X, through the second surface 22b, and through at least a portion of the second limiting portion 22 along the third direction Y, through the third surface 22c. The third direction Y is perpendicular to both the first direction Z and the second direction X. Based on the above design, when the tailgate is opened, the second limiting part 22 needs to separate from the first limiting part 12. In order to prevent the interference fit between the second limiting part 22 and the first limiting part 12 from being too large, which would make it difficult for the second limiting part 22 to separate from the second groove 121, the second limiting part 22 is provided with a first opening 224 and a second opening 225, so that the second limiting part 22 can undergo slight deformation, making it easy to open the tailgate.

[0059] In some embodiments, such as Figure 4 , Figure 8 and Figure 12 As shown, the tailgate limiting assembly 100 also includes a buffer block 50, and the second limiting portion 22 is further provided with a buffer groove 226. The second limiting portion 22 also includes a fourth surface 22d, which is disposed opposite to the third surface 22c. The buffer groove 226 is disposed on the fourth surface 22d. The first opening 224 and the second opening 225 penetrate the second limiting portion 22 and communicate with the buffer groove 226. The buffer block 50 is disposed in the buffer groove 226. At this time, during the process of opening the tailgate 300, the second limiting portion 22 located at the first opening 224 and the second opening 225 will deform, and the buffer block 50 can fill part of the first opening 224 and the second opening 225, supporting the second limiting portion 22 and preventing the second limiting portion 22 located at the first opening 224 and the second opening 225 from being damaged due to excessive deformation.

[0060] For example, the material of the buffer block 50 may include rubber, such that the buffer block 50 can absorb part of the deformation of the second limiting portion 22 and prevent damage to the second limiting portion 22. For example, the material of the buffer block 50 includes at least one of natural rubber and nitrile rubber.

[0061] In some embodiments, such as Figure 4 and Figure 5As shown, the tailgate limiting assembly 100 also includes a first fastener 41 and a second fastener 42, and the second mounting portion 21 is further provided with a first mounting hole 214 and a second mounting hole 215. The first fastener 41 is located in the first mounting hole 214, and the end near the second limiting portion 22 does not extend beyond the surface of the second mounting portion 21 near the second limiting portion 22. The second fastener 42 is located in the second mounting hole 215, and the end near the second limiting portion 22 does not extend beyond the surface of the second mounting portion 21 near the second limiting portion 22. At this time, the first fastener 41 and the second fastener 42 achieve a fixed connection between the second mounting part 21 and the tailgate 300. The end of the first fastener 41 near the second limiting part 22 does not exceed the surface of the second mounting part 21 near the second limiting part 22, and the end of the second fastener 42 near the second limiting part 22 does not exceed the surface of the second mounting part 21 away from the tailgate 300. This ensures that the first fastener 41 and the second fastener 42 will not interfere with the movement of the second limiting part 22, thus ensuring the smooth completion of the adjustment process of the relative movement of the second limiting part 22 and the second mounting part 21 along the first direction Z.

[0062] For example, the shape of the first mounting hole 214 and / or the second mounting hole 215 includes a trapezoidal shape or a cylindrical shape with a boss.

[0063] In some embodiments, such as Figure 3 As shown, the tailgate limiting assembly 100 also includes a third fastener 43 and a fourth fastener 44. The first mounting portion 11 is also provided with a third mounting hole 111 and a fourth mounting hole 112. The fourth mounting hole 112 extends along the first direction Z, and the third mounting hole 111 is located in the extending direction of the fourth mounting hole 112. The third fastener 43 is located inside the third mounting hole 111. The fourth fastener 44 is located inside the fourth mounting hole 112, and the first mounting portion 11 can move relative to the fourth fastener 44 along the first direction Z. At this time, by having the third fastener 43 pass through the third mounting hole 111 and the fourth fastener 44 pass through the fourth mounting hole 112, the first mounting portion 11 is fixed to the vehicle body 200. At the same time, since the third mounting hole 111 is located in the extending direction of the fourth mounting hole 112, the fourth mounting hole 112 can absorb tolerances during the assembly process, that is, the position of the first mounting portion 11 on the vehicle body 200 can be adjusted, thereby improving assembly efficiency.

[0064] For example, the shape of the fourth mounting hole 112 includes either an ellipse or a racetrack shape.
