[0001] This utility model relates to the field of vehicle tailgate technology, and in particular to a vehicle tailgate hinge, a vehicle tailgate, and a vehicle. Background Technology

[0002] The tailgate hinge assembly is one of the important components of the vehicle door system. It is a key component connecting the vehicle body and the door, and also a major load-bearing component of the door. The rear door opens and closes around the hinge axis. With the popularization and promotion of new energy vehicles, the requirements for lightweighting are becoming increasingly stringent, and the application of aluminum alloys and magnesium alloys is becoming more and more widespread.

[0003] In current technology, all hinges are made of steel. Steel hinges cannot be directly bonded to aluminum or magnesium alloy inner plates because electrochemical corrosion occurs when steel is bonded to these materials. Furthermore, mass production methods involve applying a black electrophoretic surface treatment to the steel hinges. This involves electrophoretically coating the steel surface with a uniform, organic electrophoretic paint film to isolate the steel hinge from the aluminum or magnesium alloy inner plate. However, black electrophoretic paint steel hinges suffer from high costs and incomplete sealing. Utility Model Content

[0031] like Figures 1-6 As shown, this utility model proposes a vehicle tailgate hinge, a vehicle tailgate, and a vehicle.

[0032] In one exemplary embodiment, the vehicle tailgate hinge includes:

[0033] Mounting base 1, which can be used to connect to the vehicle tailgate 8, has a mounting surface 101 facing the vehicle tailgate 8;

[0034] Gasket 2 is detachably connected to mounting surface 101. Gasket 2 at least covers mounting surface 101. After the hinge is installed, gasket 2 is located between fixed seat 1 and vehicle tailgate 8.

[0035] The swing arm is movably connected to the fixed base 1, and a connecting component is provided between the fixed base 1 and the swing arm for mutual connection.

[0036] In this embodiment, the hinge assembly can be connected to the vehicle tailgate 8 via the mounting base 1. Furthermore, by providing a gasket 2 on the mounting base 1, the mounting base 1 and the vehicle tailgate 8 are indirectly connected when the hinge assembly is installed, avoiding direct contact and thus effectively preventing electrochemical corrosion. When the hinge assembly is fixed to the vehicle tailgate 8, the gasket 2 also provides good sealing performance, effectively preventing gaps from forming between the hinge assembly and the vehicle tailgate 8 during long-term use, thus preventing the hinge assembly from loosening and extending its service life.

[0037] For example, in this embodiment, the mounting surface 101 is generally elliptical, the side of the fixing seat 1 has rounded corners, the mounting surface 101 is a plane, and the mounting surface 101 is elliptical. Similarly, the gasket 2 in this embodiment is also elliptical, which at least covers the mounting surface 101 that is in the plane, thereby ensuring that when the fixing seat 1 is installed on the vehicle tailgate 8, the fixing seat 1 is isolated from the vehicle tailgate 8, avoiding electrochemical corrosion between the two.

[0038] It is worth noting that in this embodiment, the mounting surface 101 of the fixing seat 1 can also be other shapes. Accordingly, the shape of the gasket 2 needs to be changed so that it is the same as the shape of the mounting surface 101, covering the mounting surface 101 and preventing the mounting surface 101 from contacting the vehicle tailgate 8.

[0039] It should also be noted that in this embodiment, the gasket 2 is installed on the mounting surface 101 of the fixing base 1 by adhesive bonding. An adhesive layer is provided between the gasket 2 and the mounting surface 101 of the fixing base 1, so that the gasket 2 can be easily replaced. In this embodiment, the gasket 2 is connected to the mounting surface 101 by repeated pasting to facilitate the quick installation and flexible adjustment of the gasket.

[0040] It should also be noted that the gasket 2 in this embodiment is an asbestos-free gasket 2, which can fully utilize its advantages such as chemical resistance, durability and environmental friendliness.

[0041] In an exemplary embodiment, the mounting base 1 is provided with a first mounting hole 102, the gasket 2 is provided with a second mounting hole 201 corresponding to the first mounting hole 102, and a fixing component for mutual connection is provided between the mounting base 1 and the vehicle tailgate 8.

[0042] In this embodiment, the first mounting hole 102 and the second mounting hole 201 provide an installation environment for the fixing components, enabling the fixing seat 1, the gasket 2 and the vehicle tailgate 8 to be connected.

[0043] For example, in this embodiment, there is at least one first mounting hole 102, and the number of second mounting holes 201 is the same as that of the first mounting holes 102, and their positions correspond to those of the first mounting holes 102. In this embodiment, two first mounting holes 102 are selected and are symmetrically opened on the fixing base 1, and two second mounting holes 201 are selected, corresponding one-to-one with the first mounting holes 102.

[0044] For example, the fixing assembly includes a fixing bolt 10 and a fastening nut 11. The fixing bolt 10 passes through the first mounting hole 102, the second mounting hole 201, and the vehicle tailgate 8 and is connected to the fastening nut 11. In this embodiment, the fixing assembly uses the fixing bolt 10 and the fastening nut 11 to simultaneously install the fixing seat 1 and the gasket 2 onto the vehicle tailgate 8.

[0045] It is worth noting that the fixing components in this embodiment are not limited to bolts and nuts, and other fixing methods such as clips can also be used to connect the fixing seat 1 to the vehicle tailgate 8.

[0046] It should also be noted that the screw and nut fixing method used in this embodiment allows the hinge assembly to be completely removed from the vehicle tailgate 8, which is more convenient when it is necessary to replace the hinge assembly or replace the gasket 2 separately. Simply remove the fixing bolt 10 and the fastening nut 11.

[0047] It should also be noted that in this embodiment, the fastening nut 11 is a press-fit nut, and the fastening nut 11 has a snap-fit ​​surface, through which the fastening nut 11 abuts against the vehicle tailgate 8. When the fastening nut 11 is installed, because it is a press-fit nut, during the tightening process with the fixing bolt 10, the snap-fit ​​surface of the press-fit nut itself will abut against the outer wall of the vehicle tailgate 8 to quickly achieve fixation and improve assembly efficiency.

[0048] In an exemplary embodiment, the connecting assembly includes a fixing part 3, a connecting part 5, and a connecting shaft 4. The fixing part 3 is integrally disposed on the fixing base 1, the connecting part 5 is integrally disposed on the swing arm, the connecting part 5 is disposed between the fixing part 3, and the connecting shaft 4 is disposed through the fixing part 3 and the connecting part 5. The connecting part 5 is capable of swinging around the connecting shaft 4.

[0049] In this embodiment, the connection between the swing arm and the fixed base 1 is realized through the connecting shaft 4, and the swing arm can swing around the connecting shaft 4.

[0050] For example, in this embodiment, there are two fixing parts 3, which are symmetrically arranged on the fixing base 1. The fixing parts 3 are spaced apart by a distance. The connecting part 5 is arranged between the fixing parts 3. The fixing shaft and the swing arm can be connected by passing through the fixing parts 3 and the connecting shaft 4 in sequence.

[0051] It is worth noting that in this embodiment, the number of fixing parts 3 can be increased, for example, three or four, and they are evenly arranged along the length direction of the fixing parts 3. Correspondingly, the number of connecting parts 5 is one less than the number of fixing parts 3. Each connecting part 5 is located between the fixing parts 3 and is connected by a connecting shaft 4 to improve the connection strength and enhance the stability of the swing arm when it swings.

[0052] In an exemplary embodiment, the swing arm includes a connecting plate 6, which has at least one connecting hole, and a connecting bolt 7 is provided through the connecting hole.

[0053] In this embodiment, the connecting plate 6 is mainly used to realize the swing, and the connecting bolt 7 on the swing arm is used to connect the hinge assembly to the vehicle body.

[0054] For example, in this embodiment, there may be one or more connecting holes; providing multiple holes can enhance the connection strength with the vehicle body. In this embodiment, the number of connecting bolts 7 is two.

[0055] This utility model also provides a vehicle tailgate 8, which includes the aforementioned vehicle tailgate hinge.

[0056] In an exemplary embodiment, the vehicle tailgate 8 includes an inner panel 9, the inner panel 9 having a mounting position 901, and a fixing seat 1 disposed on the mounting position 901.

[0057] In this embodiment, the hinge is installed on the inner panel 9 of the vehicle tailgate 8. The inner panel 9 has a third mounting hole corresponding to the first mounting hole 102 and the second mounting hole 201. During connection, the fixing bolt 10 passes through the first mounting hole 102, the second mounting hole 201 and the third mounting hole and then connects with the fastening nut 11.

[0058] This utility model also provides a vehicle that includes the aforementioned vehicle tailgate hinge.

[0059] In summary, this utility model, through the fixed seat 1, enables the hinge assembly to be connected to the vehicle tailgate 8. Furthermore, by providing a gasket 2 on the fixed seat 1, when the hinge assembly is installed, the fixed seat 1 and the vehicle tailgate 8 are indirectly connected due to the presence of the gasket 2, avoiding direct contact and thus effectively preventing electrochemical corrosion. When the hinge assembly is fixed to the vehicle tailgate 8, the gasket 2 also provides good sealing performance, effectively preventing gaps from forming between the hinge assembly and the vehicle tailgate 8 during long-term use, thus preventing the hinge assembly from loosening and extending its service life.

[0060] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
