Detailed Implementation

[0033] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise stated, "multiple" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] Before explaining the tailgate hinge provided in the embodiments of this application, let's first describe the application scenario of the tailgate hinge provided in the embodiments of this application: In related technologies, a tailgate hinge includes a body component and a door component, which are movably connected. The body component is used to connect to the vehicle body, and the door component is used to connect to the vehicle tailgate. When the tailgate needs to be installed on the vehicle body, the tailgate is connected to the door component, and a gasket is placed between the door component and the body. The gasket achieves sealing and waterproofing effects. Then, the door component is fixed to the vehicle body by fasteners, thus realizing the installation of the tailgate, and the tailgate can move relative to the vehicle body. However, the hardness of the gasket is relatively poor, and the presence of the gasket is equivalent to making the connection between the body component and the body body flexible. Therefore, in actual use, the tailgate hinge may lose torque. For example, if the torque for fixing the body component to the body body is 20 to ensure the stability of the door, but the gasket causes the tailgate hinge to lose torque, dropping from the torque of the tailgate hinge to 10, the tailgate may become loose, which may lead to the tailgate wobbling relative to the vehicle body.

[0037] Reference Figure 1 This illustration shows a schematic diagram of a tailgate hinge installed on a vehicle body according to an embodiment of this application; see reference Figure 2 This shows one of the bottom views of a vehicle body component provided in an embodiment of this application; refer to Figure 3 This shows a second bottom view of a vehicle body component provided in an embodiment of this application; refer to Figure 4 This shows a third bottom view of a vehicle body component provided in an embodiment of this application. For example... Figures 1 to 4 As shown, the tailgate hinge includes a door component 10 for connecting the tailgate of the vehicle.

[0038] The body component 20 is movably connected to the door component 10. The body component 20 includes a connecting surface 201, a supporting boss 30 is provided on the connecting surface 201, and a mounting hole is provided on the connecting surface 201. A fixing member 40 is provided in the mounting hole, and the fixing member 40 protrudes from the connecting surface 201. The fixing member 40 is used to connect the body component 20 to the vehicle body 001, and the supporting boss 30 is used to abut against the vehicle body 001 to support the body component 20.

[0039] In this embodiment, since the body component 20 is movably connected to the door component 10, in practical applications, the tailgate of the vehicle can be connected to the door component 10, and then the body component 20 can be installed on the vehicle body 001. Thus, when the tailgate of the vehicle is moved, the tailgate drives the door component 10 to move relative to the body component 20, thereby allowing the tailgate to move relative to the vehicle body 001, and thus allowing the tailgate to open or close. Since the connecting surface 201 of the body component 20 is provided with a support boss 30, and the connecting surface 201 is provided with a mounting hole, and the mounting hole is provided with a fastener 40, and the fastener 40 protrudes from the connecting surface 201, when it is necessary to install the body component 20 on the body 001, the body component 20 can be fixed to the body 001 by the fastener 40. Thus, the support boss 30 will be located between the connecting surface 201 of the body component 20 and the body 001, and the support boss 30 will abut against the body 001. The support boss 30 will support the body component 20, so that the body component 20 and the body 001 of the vehicle are essentially rigidly connected. That is, in this embodiment of the application, by providing a support boss 30 on the connecting surface 201 of the body part 20, when the body part 20 is fixed to the body 001 by the fastener 40, the support boss 30 supports the body part 20, and the support boss 30 has a large rigidity, thereby making the body part 20 and the vehicle body 001 rigidly connected, avoiding the problem of the tailgate hinge easily losing torque, and thus avoiding the problem of the tailgate easily loosening. That is, in this embodiment of the application, the stability of the tailgate relative to the body 001 can be effectively improved, and the tailgate is prevented from easily loosening.

[0040] It should be noted that, in this embodiment, the body component 20 and the door component 10 can be connected by a rotating shaft, thereby enabling the body component 20 and the door component 10 to be movably connected. Of course, the body component 20 and the door component 10 can also be movably connected in other ways, such as by a hinge. This embodiment does not limit the scope of this application.

[0041] In addition, in this embodiment, the shape of the body part 20 and the shape of the door part 10 can be set according to actual needs, and this embodiment does not limit them here.

[0042] In addition, in this embodiment, the fastener 40 can be a bolt. Of course, the fastener 40 can also be other components with a fastening function, such as a pin. The specific type of the fastener 40 is not limited in this embodiment.

[0043] In some embodiments, the support boss 30 may include a first sub-support platform 31 and a second sub-support platform 32; the first sub-support platform 31 and the second sub-support platform 32 are spaced apart along a first direction, and the fixing member 40 is located between the first sub-support platform 31 and the second sub-support platform 32. The first direction is the direction from one side to the other of the two opposite sides of the connecting surface 201; both the first sub-support platform 31 and the second sub-support platform 32 are used to abut against the vehicle body 001 to support the body component 20.

[0044] Since the first sub-support platform 31 and the second sub-support platform 32 are spaced apart along the first direction, and the fixing member 40 is located between the first sub-support platform 31 and the second sub-support platform 32, when the body component 20 is fixed to the body 001 by the fixing member 40, both the first sub-support platform 31 and the second sub-support platform 32 abut against the body 001 of the vehicle. Furthermore, the first sub-support platform 31 and the second sub-support platform 32 can ensure that the body component 20 is supported relatively stably, avoiding the possibility of the body component 20 tilting. In other words, by setting the first sub-support platform 31 and the second sub-support platform 32, while ensuring a rigid connection between the body component 20 and the body 001, it is also possible to ensure that the body component 20 is stably supported.

[0045] It should be noted that the thickness of the first sub-support platform 31 and the second sub-support platform 32 can be equal. The thickness of the first sub-support platform 31 is the distance between the surface of the first sub-support platform 31 away from the connecting surface 201 and the surface of the first sub-support platform 31 connected to the connecting surface 201.

[0046] Furthermore, in this embodiment, the shape of the first sub-support platform 31 can be set according to actual needs. For example, the shape of the first sub-support platform 31 can be a cuboid, or for example, a cylinder. This embodiment does not limit the specific shape of the first sub-support platform 31. Additionally, the shape of the second sub-support platform 32 can also be set according to actual needs. The shape of the second sub-support platform 32 can be the same as that of the first sub-support platform 32, improving the aesthetics of the tailgate hinge. Of course, the shape of the second sub-support platform 32 can also be different from that of the first sub-support platform 32; this embodiment does not limit this.

[0047] In addition, in some embodiments, the support boss 30 may also include a third sub-support platform 33 and a fourth sub-support platform 34; the third sub-support platform 33 and the fourth sub-support boss 30 are both located between the first sub-support platform 31 and the second sub-support platform 32, and the third sub-support platform 30 and the fourth sub-support boss 30 are spaced apart along a second direction, which is the direction intersecting with the first direction; the third sub-support platform 33 and the fourth sub-support platform 34 are both used to abut against the vehicle body 001 to support the body component 20.

[0048] Since the third sub-support platform 33 and the fourth sub-support boss 30 are both located between the first sub-support platform 31 and the second sub-support platform 32, and the third sub-support boss 30 and the fourth sub-support boss 30 are spaced apart along the second direction, when the body component 20 is fixed to the body 001 by the fastener 40, the first sub-support platform 31 and the second sub-support platform 32 are both in contact with the vehicle body 001, and the third sub-support platform 33 and the fourth sub-support platform 34 are both in contact with the vehicle body 001. Therefore, the body component 20 is not only stably supported in the first direction, but also stably supported in the second direction, effectively preventing the body component 20 from tilting. In other words, by setting the third sub-support platform 33 and the fourth sub-support platform 34, while ensuring a rigid connection between the body component 20 and the body 001, the stable support of the body component 20 can be further ensured.

[0049] It should be noted that the thickness of the third sub-support platform 33 and the fourth sub-support platform 34 can be equal, and the thickness of the third sub-support platform 33 can be equal to the thickness of the first sub-support platform 31. The thickness of the third sub-support platform 33 is defined as the distance between the surface of the third sub-support platform 33 facing away from the connecting surface 201 and the surface of the third sub-support platform 33 connected to the connecting surface 201.

[0050] Furthermore, in this embodiment, the shape of the third sub-support platform 33 can be set according to actual needs. For example, the shape of the third sub-support platform 33 can be a cuboid, or a trapezoid. The specific shape of the third sub-support platform 33 is not limited in this embodiment. Additionally, the shape of the fourth sub-support platform 34 can also be set according to actual needs. The shape of the fourth sub-support platform 34 can be the same as that of the third sub-support platform 33 to improve the aesthetics of the tailgate hinge. Of course, the shape of the fourth sub-support platform 34 can also be different from that of the third sub-support platform 33; this is not limited in this embodiment.

[0051] In addition, in some embodiments, the support boss 30 may also include a fifth sub-support platform 35, the fastener 40 includes a first sub-component 41 and a second sub-component 42, the first sub-component 41 and the second sub-component 42 are spaced apart along a first direction, and the first sub-component 41 and the second sub-component 42 are both located between the first sub-support platform 31 and the second sub-support platform 32; the fifth sub-support platform 35 is located between the first sub-component 41 and the second sub-component 42.

[0052] Since the first sub-component 41 and the second sub-component 42 are spaced apart along the first direction, when the body component 20 is fixed to the body 001 by the fastener 40, the body component 20 can be fixed to the body 001 by the first sub-component 41 and the second sub-component 42, thereby improving the stability of the body component 20. In addition, the fifth sub-support platform 35 is located between the first sub-component 41 and the second sub-component 42. Once the first sub-component 41 and the second sub-component 42 fix the body component 20 to the body 001, the fifth sub-support platform 35 will come into contact with the vehicle body 001. As a result, the first sub-support platform and the second sub-support platform 32 will also come into contact with the vehicle body 001. Thus, the presence of the fifth sub-support platform 35 increases the support points for the body component 20, making the body component 20 more stable.

[0053] It should be noted that the fifth sub-support platform 35 can have the same thickness as the first sub-support platform 31. The thickness of the fifth sub-support platform 35 is defined as the distance between the surface of the fifth sub-support platform 35 facing away from the connecting surface 201 and the surface of the fifth sub-support platform 35 connected to the connecting surface 201.

[0054] Furthermore, in this embodiment, the shape of the fifth sub-support platform 35 can be set according to actual needs. For example, the shape of the fifth sub-support platform 35 is a cube, and the shape of the third sub-support platform 33 is a trapezoid. The specific shape of the fifth sub-support platform 35 is not limited in this embodiment.

[0055] In addition, in some embodiments, the tailgate hinge may also include a gasket 50; the gasket 50 is provided with a first through hole, the gasket 50 is disposed on the connecting surface 201, and the fastener 40 passes through the first through hole, the gasket 50 is located between the first sub-support platform 31 and the second sub-support platform 32, and the gasket 50 is used to contact the vehicle body 001.

[0056] Because the tailgate gasket 50 has a first through hole and is located on the connecting surface 201, the fastener 40 can pass through the first through hole, allowing the fastener 40 to connect the body component 20 to the vehicle body 001. Furthermore, the gasket 50 is located between the first sub-support platform 31 and the second sub-support platform 32. Therefore, once the body component 20 is fixed to the body body 001 by the fastener 40, not only the first sub-support platform 31 and the second sub-support platform 32 are in contact with the body body 001, but the gasket 50 will also be in contact with the body body 001. Thus, the gasket 50 can effectively seal and waterproof the body component 20, ensuring minimal liquid flow at the tailgate hinge and preventing problems affecting the body body 001. In other words, by using the gasket 50, the sealing and waterproofing between the body component 20 and the body body 001 can be effectively improved.

[0057] It should be noted that the material of the gasket 50 can be selected according to actual needs, and the strength of the gasket 50 is less than the strength of the supporting boss 30. The supporting boss 30 can be made of metal, for example, an alloy, or steel. This embodiment of the application does not limit this. Additionally, the gasket 50 can be made of hard rubber, hard plastic, etc. This embodiment of the application does not limit this either.

[0058] In addition, in some embodiments, there is a first gap L1 between the gasket 50 and the first sub-support 31, and a second gap L2 between the gasket 50 and the second sub-support 32.

[0059] Because the gasket 50 may have tolerances during the manufacturing process, its installation may be difficult. In this embodiment, by setting a first gap L1 between the gasket 50 and the first sub-support 31, and a second gap L2 between the gasket 50 and the second sub-support 32, the tolerances of the gasket 50 are taken into account, and space is reserved, making the installation of the gasket 50 easier.

[0060] It should be noted that the specific values ​​of the first gap L1 and the second gap L2 can be set according to actual needs. For example, both the first gap L1 and the second gap L2 can be 1 mm, or both can be 2 mm. This application does not limit the specific values ​​of these gaps in the embodiments.

[0061] In addition, in this embodiment, the gasket 50 can contact the first sub-support 31 and the second sub-support 32, which means that the processing of the gasket 50 is accurate enough, that is, the gasket 50 has no tolerance, so that the gasket 50 can contact both the first sub-support 31 and the second sub-support 32 at the same time.

[0062] In addition, in some embodiments, the thickness of the gasket 50 is greater than or equal to the thickness of the first sub-support platform 31, the thickness of which is the distance between the surface of the first sub-support boss 30 away from the connecting surface 201 and the surface of the first sub-support platform 31 connected to the connecting surface 201.

[0063] With this configuration, when the fastener 40 secures the body component 20 to the body 001, the gasket 50 can be compressed. This allows the gasket 50 to effectively seal the gap between the body component 20 and the body 001, and also ensures good waterproofing at the location on the body 001 where the body component 20 is mounted. Specifically, by setting the thickness of the gasket 50 to be greater than or equal to the thickness of the first sub-support platform 31, the gasket 50 can effectively ensure a seal and waterproofing between the body component 20 and the body 001.

[0064] In addition, in some embodiments, the support boss 30 may also include a fifth sub-support platform 35, which is located between the first sub-support platform 31 and the second sub-support platform 32; the gasket 50 is provided with a second through hole 501, the fifth sub-support platform 35 is located in the second through hole 501, and there is a third gap L3 between the outer wall of the fifth sub-support platform 35 and the hole wall of the second through hole 501.

[0065] Because the gasket 50 has a second through hole 501, when the gasket 50 is placed on the connecting surface 201, the fifth sub-support platform 35 can be positioned within the second through hole 501, thus preventing the gasket 50 from obstructing the fifth sub-support platform 35. Furthermore, there is a third gap L3 between the outer wall of the fifth sub-support platform 35 and the wall of the second through hole 501, ensuring that the gasket 50 is less obstructed during installation, making installation easier.

[0066] It should be noted that the shape of the second through hole 501 can be the same as the cross-sectional shape of the fifth sub-support platform 35. Furthermore, the value of the third gap L3 can be set according to actual needs; for example, the third gap L3 can be 1 mm, or even 2 mm. This embodiment of the application does not limit this specific value.

[0067] In addition, in some embodiments, the support boss 30 may also include a third sub-support platform 33 and a fourth sub-support platform 34; the third sub-support platform 33 and the fourth sub-support boss 30 are both located between the first sub-support platform 31 and the second sub-support platform 32, and the third sub-support boss 30 and the fourth sub-support boss 30 are spaced apart along the second direction; the gasket 50 is provided with a first clearance groove and a second clearance groove on two opposite sides along the second direction, at least a portion of the third sub-support platform 33 is located in the first clearance groove and has a fourth gap L4 between it and the groove wall of the first clearance groove, and at least a portion of the fourth sub-support platform 34 is located in the second clearance groove and has a fifth gap L5 between it and the groove wall of the second clearance groove.

[0068] Since at least a portion of the third sub-support platform 33 is located in the first clearance groove and has a fourth gap L4 between it and the groove wall of the first clearance groove, and at least a portion of the fourth sub-support platform 34 is located in the second clearance groove and has a fifth gap L5 between it and the groove wall of the second clearance groove, the area of ​​the gasket 50 on the connecting surface 201 can be made as large as possible. This improves the sealing and waterproofing performance of the gasket 50 when sealing and waterproofing the gap between the body part 20 and the body 001. Furthermore, when the gasket 50 is placed on the connecting surface 201, it can be ensured that the gasket 50 is less obstructed during installation, making it easier to install the gasket 50.

[0069] It should be noted that the value of the fourth gap L4 can be set according to actual needs. For example, the fourth gap L4 can be 1 mm, or for another example, it can be 2 mm. This application embodiment does not limit this value. Similarly, the value of the fifth gap L5 can be set according to actual needs. For example, the fifth gap L5 can be 1 mm, or for another example, it can be 2 mm. This application embodiment does not limit this value.

[0070] Furthermore, in this embodiment, the support boss 30 can be an integral structure with the body part 20. That is, the support boss 30 can be directly formed on the body part 20 during the production process of the body part 20 through die casting or other processes, thereby improving the strength of the body part 20. Of course, the fixing boss can also be fixed to the body part 20 by welding or by screws. This embodiment does not limit the scope of this application.

[0071] In addition, in this embodiment of the application, when the support boss 30 is formed on the body part 20, the target torque required for the rigid connection can be determined based on the working condition of the tailgate. Then, according to the target torque and in combination with the tolerance, the radial load of the radial load body part 20 is determined. Then, based on the radial load of the body part 20 or the yield strength of the body 001 material, the minimum required area of ​​the rigid connection is determined. Then, based on the area of ​​the rigid connection, the area of ​​the support boss 30 is determined. The area of ​​the support boss 30 is greater than or equal to the area of ​​the rigid connection. The area of ​​the support boss 30 is the area of ​​the surface of the support boss 30 in contact with the body 001, or the area of ​​the support boss 30 projected onto the connection surface 201.

[0072] Furthermore, in this embodiment, an opening can be formed at a location on the connecting surface 201 where the support protrusion 30 is not provided. This allows less electrophoretic liquid to remain on the connecting surface 201 during electrophoresis of the body part 20, allowing it to flow out through the opening. For example, the gap between the first sub-support platform 31 and the second sub-support platform 32 can serve as an opening, allowing the electrophoretic liquid to flow out through this gap during electrophoresis of the body part 20, thus preventing the electrophoretic liquid from adhering to the connecting surface 201.

[0073] In this embodiment, since the body component 20 is movably connected to the door component 10, in practical applications, the tailgate of the vehicle can be connected to the door component 10, and then the body component 20 can be installed on the vehicle body 001. Thus, when the tailgate of the vehicle is moved, the tailgate drives the door component 10 to move relative to the body component 20, thereby allowing the tailgate to move relative to the vehicle body 001, and thus allowing the tailgate to open or close. Since the connecting surface 201 of the body component 20 is provided with a support boss 30, and the connecting surface 201 is provided with a mounting hole, and the mounting hole is provided with a fastener 40, and the fastener 40 protrudes from the connecting surface 201, when it is necessary to install the body component 20 on the body 001, the body component 20 can be fixed to the body 001 by the fastener 40. Thus, the support boss 30 will be located between the connecting surface 201 of the body component 20 and the body 001, and the support boss 30 will abut against the body 001. The support boss 30 will support the body component 20, so that the body component 20 and the body 001 of the vehicle are essentially rigidly connected. That is, in this embodiment of the application, by providing a support boss 30 on the connecting surface 201 of the body part 20, when the body part 20 is fixed to the body 001 by the fastener 40, the support boss 30 supports the body part 20, and the support boss 30 has a large rigidity, thereby making the body part 20 and the vehicle body 001 rigidly connected, avoiding the problem of the tailgate hinge easily losing torque, and thus avoiding the problem of the tailgate easily loosening. That is, in this embodiment of the application, the stability of the tailgate relative to the body 001 can be effectively improved, and the tailgate is prevented from easily loosening.

[0074] This application provides a vehicle comprising a body 001, a tailgate, and a tailgate hinge as described in any of the above embodiments. The tailgate is connected to a door component 10, and a body component 20 is connected to the body 001 via a fastener 40, with a support boss 30 abutting against the body 001.

[0075] It should be noted that the vehicle can be an electric vehicle or a gasoline-powered vehicle. In addition, the vehicle can include models such as sedans and SUVs.
