[0034] Figures 1 to 7 The structural schematic diagram of the back door hinge structure provided by the embodiment of the present utility model is shown. As Figures 1 to 7 shown, the first embodiment of the present utility model provides a back door hinge structure, including a hinge 1 and a hinge trim 2. The hinge trim 2 covers the outside of the hinge 1 and is detachably connected to the hinge 1. One end of the hinge 1 is also connected to the back door interior trim panel 20, and one end of the hinge trim 2 is also detachably connected to the back door interior trim panel 20 to cover the connection between the hinge 1 and the back door interior trim panel 20.

[0035] Specifically, the hinge trim 2 can be a cover body that covers the outside of the hinge 1 to decorate and protect the hinge 1; one end of the hinge 1 is connected to the back door interior trim panel 20, and one end of the hinge trim 2 is also detachably connected to the back door interior trim panel 20. The cover body at the end of the hinge trim 2 is used to decorate and protect the connection between the hinge 1 and the back door interior trim panel 20, thereby decorating and protecting all parts of the hinge 1. Since the connection between the hinge 1 and the back door interior trim panel 20 is fixed, when the back door is opened or closed and the hinge 1 moves relative to this connection, the hinge 1 and the components near the connection of the hinge 1 can be blocked and hidden by the hinge trim 2, improving the aesthetics of the vehicle.

[0036] The hinge decorative part 2 covers the outer side of the hinge 1 and is detachably connected to the hinge 1 and the rear door interior trim panel 20. When installing the rear door hinge structure, first connect the hinge 1 to the rear door interior trim panel 201, and then cover and install the hinge decorative part 2 on the outer side of the hinge 1; when disassembling the hinge 1, first disassemble the outermost hinge decorative part 2, and then disassemble the hinge 1 from the rear door interior trim panel 20, which is convenient and fast for disassembly and assembly. In addition, when disassembling the rear door hinge for maintenance, one end of the hinge decorative part 2 is disassembled from one end of the rear door interior trim panel 20, and then one end of the hinge 1 is disassembled from the rear door interior trim panel 20. There is no need to disassemble the rear door interior trim panel 20, and the connection parts of the hinge 1 and the hinge decorative part 2 with the rear door interior trim panel 20 are fewer, which can reduce the damage to the rear door interior trim panel 20.

[0037] The rear door hinge structure provided by the embodiment of the present utility model wraps the hinge 1 by arranging the hinge decorative part 2 on the outer side of the hinge 1, and detachably connects the hinge decorative part 2 to the hinge 1. At the same time, at the position where the hinge is connected to the rear door interior trim panel 20, one end of the hinge decorative part 2 is also detachably connected to the rear door interior trim panel 20 to cover the connection part between the hinge 1 and the rear door interior trim panel 20, so as to realize the quick and convenient disassembly and assembly of the hinge 1, and will not damage components such as the rear door interior trim panel 20, improve the disassembly and assembly efficiency, and reduce the hinge maintenance and replacement costs; in addition, the hinge 1 and the components near the connection part of the hinge 1 can be effectively blocked and hidden by the hinge decorative part 2, enhancing the aesthetics of the vehicle.

[0038] In some embodiments, as Figure 1 、 Figures 3 to 7 shown, the hinge decorative part 2 includes a connection part 21 connected to the rear door interior trim panel 20 and a first decorative part 22 covering the outer side of the hinge 1. The first decorative part 22 has a decorative cavity 23 for accommodating the hinge 1. A hinge installation part 201 for installing the hinge 1 is provided on the rear door interior trim panel 20. The hinge 1 extends from the hinge installation part 201 into the inner side of the rear door interior trim panel 20 and is connected to the rear door interior trim panel 20. The connection part 21 covers the outer side of the hinge installation part 201 and is connected to the hinge installation part 201.

[0039] The connection part 21 is used to cover the components around the connection part between the hinge 1 and the rear door interior trim panel 20, and the decorative cavity 23 of the first decorative part 22 is used to cover the main body part of the hinge 1, realizing the multi-directional covering and hiding of the hinge 1. A hinge installation part 201 is provided on the rear interior trim panel 20, and one end of the hinge 1 extends from the hinge installation part 201 into the inner side of the rear door interior trim panel 20 and is fixed to the rear door interior trim panel 20. The hinge installation part 201 is connected to the connection part 21 of the hinge decorative part 2 on the outer side of the hinge installation part 201, so that the connection part 21, the hinge installation part 201, and the hinge 1 are arranged in sequence from outside to inside, effectively blocking the components at one end where the hinge 1 is connected to the rear door interior trim panel 20.

[0040] In addition, in this embodiment, one end of the hinge 1 extends into the inner side of the rear door interior trim panel 20. The size of the part of the hinge 1 extending into the inner side of the rear door interior trim panel 20 can be set relatively (relative to the hinge mounting portion 201) to be reliably connected to the inner wall of the rear door interior trim panel 20. At the same time, the thickness of one end of the hinge 1 can be set to be relatively thick to further ensure reliable connection with the rear door interior trim panel 20. In addition, the hinge mounting portion 201 can also serve as a primary baffle to protect one end of the hinge 1. After one end of the hinge decorative member 2 is connected to the rear door interior trim panel 20, the hinge decorative member 2 is used for secondary protection. Extending one end of the hinge 1 into the inner side of the rear door interior trim panel 20 can provide a certain installation space for the connecting member between the hinge decorative member 2 and the rear door interior trim panel 20 when the hinge decorative member 2 is connected to the rear door interior trim panel 20, avoiding interference between the connection of the hinge 1 and the rear door interior trim panel 20 and the connection of the hinge decorative member 2 and the rear door interior trim panel 20.

[0041] In specific implementation, one end of the hinge 1 can also be directly installed on the outer side of the hinge mounting portion 201. Then, one end of the hinge decorative member 2 is connected to the rear door interior trim panel 20 to decorate and protect the connection part of the hinge 1. In some embodiments, as Figure 4 and Figure 6 shown, a hinge installation opening 202 is formed on the hinge mounting portion 201. The hinge 1 extends into the inner side of the rear door interior trim panel 20 from the hinge installation opening 202 and is connected to the rear door interior trim panel 20 through a fastener 3.

[0042] By providing the hinge installation opening 202 on the hinge mounting portion 201, the hinge 1 can be limited by the hinge installation opening 202, and then the hinge 1 is fixedly connected to the rear door interior trim panel 20 through the fastener 3 (such as a bolt) to ensure the reliability of their connection.

[0043] As Figure 4 shown, after the hinge decorative member 2 is removed, the installation bolts of the rear door hinge are exposed, and the bolts can be conveniently removed. After the bolts are removed, the hinge 1 is pulled out along the arrow direction in the figure, and the disassembly and adjustment of the rear door hinge can be achieved.

[0044] Optionally, as Figure 4 shown, the hinge mounting portion 201 is of a frame structure, including a plurality of frame openings. One end of the hinge 1 is exposed relative to the frame openings, and the fastener 3 is installed at the frame openings, that is, the fastener 3 does not need to be connected to the rear door interior trim panel 20. The fastener 3 passes through the hinge 1 to fix the hinge 1 to other components inside the rear door interior trim panel 20. In this way, when the hinge 1 is disassembled, the fastener 3 is disassembled from the hinge 1. The fastener 3 is not in contact connection with the rear door interior trim panel 20, will not cause damage to the rear door interior trim panel 20, and can reduce the weight of the hinge mounting portion 201.

[0045] In some other embodiments, there is no need to provide a hinge installation opening 202 in the hinge installation portion 201. The hinge 1 can be extended into the inner side of the back door interior trim panel 20 from the edge of the hinge installation portion 201, and the hinge 1 and the back door interior trim panel 20 are fixedly connected by a fastener 3. However, since the hinge 1 is relatively long, the hinge 1 may shift left and right, resulting in unreliable connection.

[0046] In some embodiments, as Figure 5 shown, the connecting portion 21 is interference-connected to the hinge installation portion 201, and the interference amount between the connecting portion 21 and the hinge installation portion 201 is 1.0 mm to 1.4 mm.

[0047] The connecting portion 21 of the hinge decorative member 2 is interference-connected to the hinge installation portion 201 of the back interior trim panel 20, and the interference amount therebetween is set to be between 1.0 mm and 1.4 mm, for example, 1.2 mm. While ensuring reliable interference connection between the two, the aesthetics and delicate appearance after their mating connection are ensured. When the interference amount is too large, the two may not be connectable; when the interference amount is too small, the two may not be reliably connected, resulting in possible gaps between the two and affecting the external aesthetics after their connection.

[0048] In some embodiments, as Figure 5 and Figure 6 shown, a connecting groove 203 connected to the connecting portion 21 is provided on the hinge installation portion 201. By using the connecting grooves 203 provided on the left and right sides of the hinge installation portion 201 to connect with the connecting portion 21, the connecting portion 21 can be inserted into the connecting groove 203 to cooperate with the back door interior trim panel 20. While realizing fast and reliable assembly of the two, the mating gap between the two is hidden, further ensuring the external aesthetics after their connection.

[0049] In some embodiments, as Figure 5 and Figure 6 shown, the connecting portion 21 is docked with the back door interior trim panel 20 on one side of the hinge installation portion 201 to form a second decorative portion 4.

[0050] On the back door interior trim panel 20, a docking portion 204 for docking with the connecting portion 21 is provided on one side where the hinge installation portion 201 is located (the outer side of the back door interior trim panel 20). After the connecting portion 21 is docked with the docking portion 204, the outer wall of the back door interior trim panel 20 on the side of the hinge installation portion 201 is seamlessly docked with the outer wall of the connecting portion 21, forming an integral second decorative portion 4, ensuring the external aesthetics after the connection of the hinge decorative member 2 and the back door interior trim panel 20.

[0051] In this embodiment, through the docking of the connecting portion 21 with the inner trim panel 20 of the rear door, the interference connection between the connecting portion 21 and the hinge mounting portion 201, and the connecting groove 203, etc., the gap structure between the hinge trim 2 and the inner trim panel 20 of the rear door can be effectively hidden, improving the refinement of the overall structure after their cooperation.

[0052] Preferably, the connecting portion 21 is a first U-shaped structure, and the top wall of the first U-shaped structure is in smooth transition with the top wall of the inner trim panel 20 of the rear door.

[0053] The connecting portion 21 adopts a first U-shaped structure, the U-shaped opening of the first U-shaped structure faces the hinge mounting portion 201, the two side walls of the first U-shaped structure are connected to the hinge mounting portion 201, and after being docked with the docking portion 204, a closed decorative cavity is formed to hide and protect the components at the hinge 1 connection (such as hiding the fastener 3), and the top wall of the first U-shaped structure is flush with the top wall of the inner trim panel 20 of the rear door in smooth transition, forming a flat and aesthetically pleasing second decorative portion 4.

[0054] Preferably, the first decorative portion 22 is a second U-shaped structure, and the second U-shaped structure has a U-shaped decorative cavity. The U-shaped decorative cavity of the second U-shaped structure can directly hide and protect the hinge 1, and the two side walls of the second U-shaped structure can effectively limit the position of the hinge 1. In a specific implementation, the connecting portion 21 and the first decorative portion 22 can also be structures in shapes such as square and trapezoid, and the specific shape is not specifically limited in the present invention.

[0055] In addition, the first decorative portion 22 is set as a U-shaped structure, which facilitates the hinge 1 to move flexibly along with the opening and closing of the rear door by using the U-shaped opening of the U-shaped structure, ensuring the smooth opening and closing of the rear door. In a specific implementation, the first decorative portion 22 can also be a cylindrical structure, or other structures with a decorative cavity 23 in other shapes.

[0056] In some embodiments, such as Figure 3 、 Figure 5 or Figure 7 as shown, the cavity wall of the decorative cavity 23 is provided with a limiting rib 24, and the width of the limiting rib 24 is 0.1 mm to 0.3 mm. The width of the limiting rib 24 is the gap (single-sided gap) between the hinge 1 and the cavity wall of the decorative cavity 23. Setting this gap to 0.1 mm to 0.3 mm, for example, 0.2 mm, not only limits the relative position between the two, but also prevents the rattling noise between them. At the same time, the limiting rib 24 can strengthen the hinge trim 2. Since the first decorative portion 22 is a second U-shaped structure, the limiting rib 24 is preferably a U-shaped limiting rib and is arranged at intervals along the length direction of the decorative cavity 23, ensuring the reliable connection between the hinge trim 2 and the hinge 1 and avoiding rattling noise.

[0057] In some embodiments, such as Figures 1 to 7As shown, the hinge 1 and the hinge trim 2 are connected by a snap 51, and the hinge 1 and the hinge trim 2 are respectively provided with a clamping hole 52 that cooperates with the snap 51.

[0058] Through the snap-fit cooperation of the snap 51 with the clamping holes 52 on the hinge 1 and the hinge trim 2, the quick disassembly and assembly of the hinge trim 2 can be realized. The first decorative part 22 of the hinge trim 2 is a second U-shaped structure, and clamping holes 52 can be respectively opened on the upper and lower side walls of the second U-shaped structure to reliably connect the hinge 1 and the hinge trim 2. The connecting part 21 of the hinge trim 2 is also connected to the rear door interior trim panel 20 through the snap 51 to realize the quick disassembly and assembly of the hinge trim 2. The aperture of the clamping hole 52 is preferably 7 mm to ensure firm clamping without falling off.

[0059] Optionally, since one end of the hinge 1 extends into the inner side of the rear door interior trim panel 20, as Figure 1 shown, a concave clamping position can be provided at one end of the hinge trim 2, and a clamping hole 52 can be opened on the concave clamping position to ensure reliable snap-fit of the snap 51 with the clamping hole 52.
