[0037] The embodiment of the present application provides a vehicle door hinge structure 100, which is applied to a vehicle. The vehicle door hinge structure 100 is used to connect a vehicle door 200 and a vehicle body 300 of the vehicle to each other; Figure 1-4 , the door hinge structure 100 comprises:

[0038] A first hinge member 1 and a second hinge member 2 that are hinged to each other, wherein the first hinge member 1 is used to be fixedly connected to the vehicle door 200, and the second hinge member 2 is used to be fixedly connected to the vehicle body 300;

[0039] A positioning assembly 3, wherein the positioning assembly 3 is mounted on the second hinge member 2, and the positioning assembly 3 can be lockably slidably connected relative to the second hinge member 2; the positioning assembly 3 is used to cooperate with the positioning hole 310 of the vehicle body 300 to limit the relative position of the second hinge member 2 and the vehicle body 300.

[0040] The vehicle door hinge structure 100 provided in the embodiment of the present application comprises a first hinge member 1 and a second hinge member 2 which are hinged to each other. The first hinge member 1 is fixedly connected to the vehicle door 200, and the second hinge member 2 is fixedly connected to the vehicle body 300, so as to realize the rotation connection between the vehicle door 200 and the vehicle body 300. Among them, a positioning component 3 is installed on the second hinge member 2, and the positioning component 3 can be locked and slidably connected relative to the second hinge member 2. During the assembly process of the vehicle door 200, the vehicle door hinge structure 100 is first installed with the vehicle door 200, and then the position of the positioning component 3 relative to the second hinge member 2 is adjusted according to the size and position relationship between the vehicle door 200 and the vehicle body 300. Finally, the positioning component 3 and the positioning hole 310 of the vehicle door 200 are used as the positioning reference, and the vehicle door hinge structure 100 is installed with the vehicle body 300, thereby completing the assembly of the vehicle door 200. The above-mentioned position adjustment process of the positioning component 3 is equivalent to the preliminary positioning of the vehicle door 200 and the vehicle body 300, thereby interrupting the position dimension chain of the vehicle door 200 and the vehicle body 300 to improve the assembly accuracy of the vehicle door 200 and the vehicle body 300, avoiding a lot of time and manual adjustments in the later stage, and ensuring that the gap surface difference between the vehicle door 200 and the vehicle body 300 is within the preset range, and improving the assembly stability of the vehicle door 200 and the vehicle body 300.

[0041] It should be noted that, in the embodiment of the present application, the first hinge member 1 is fixedly sleeved with a hinge bushing 7, the interior of the hinge bushing 7 is rotatably sleeved with a first side of a hinge pin 8, and the second side of the hinge pin 8 is fixedly connected to the second hinge member 2. In this arrangement, the hinge bushing 7 and the hinge pin 8 are rotatably connected to each other to realize the rotational connection between the first hinge member 1 and the second hinge member 2, thereby realizing the rotational connection between the vehicle door 200 and the vehicle body 300, and the structure is simple and practical.

[0042] In the embodiment of the present application, the first hinge member 1 includes a first mounting hole 101, and the first mounting hole 101 is used for a first fixing bolt (not shown in the drawings) to pass through, so as to use the first fixing bolt to fix the first hinge member 1 and the vehicle door 200 to each other. In this way, the first fixing bolt passes through the first mounting hole 101 and is fixedly connected to the vehicle door 200 to achieve mutual fixation of the first hinge member 1 and the vehicle door 200, and the structure is simple and practical.

[0043] Among them, in the embodiment of the present application, the second hinge member 2 includes a second mounting hole 201, and the second mounting hole 201 is used for a second fixing bolt (not shown in the drawings) to pass through, so as to use the second fixing bolt to fix the second hinge member 2 and the vehicle body 300 to each other. The second fixing bolt passes through the second mounting hole 201 and is fixedly connected to the vehicle body 300 to achieve the mutual fixation of the second hinge member 2 and the vehicle body 300, and the structure is simple and practical. Further, in some embodiments of the present application, the door hinge structure 100 includes at least two second mounting holes 201, and at least two second mounting holes 201 are symmetrically arranged on opposite sides of the positioning component 3. In this way, the connection firmness between the second hinge member 2 and the vehicle body 300 is improved by at least two second mounting holes 201, and at the same time, the at least two second mounting holes 201 are symmetrically arranged on opposite sides of the positioning component 3 to ensure that the opposite sides of the positioning component 3 are balanced.

[0044] In some embodiments of the present application, refer to the attached Figure 1-2 The second hinge member 2 includes a through hole portion 202; the positioning assembly 3 includes a positioning pin 4 and a locking bolt 5, the positioning pin 4 is used to be inserted and matched with the positioning hole 310, the first end of the positioning pin 4 along its length direction is provided with a threaded hole 401, and the second end of the positioning pin 4 along its length direction is used to be inserted into the positioning hole 310; the locking bolt 5 includes a bolt head 501 and a threaded portion 502 connected to each other, the threaded portion 502 passes through the through hole portion 202 and is threadedly connected to the threaded hole 401, so that the locking bolt 5, the second hinge member 2 and the positioning pin 4 are fixed to each other; wherein the cross-sectional diameter of the threaded portion 502 is smaller than the aperture of the through hole portion 202. In this arrangement, since the cross-sectional diameter of the threaded portion 502 is smaller than the aperture of the through hole portion 202, there is a certain movable gap between the threaded portion 502 and the through hole portion 202, and the movable gap is the position adjustment range of the positioning assembly 3 relative to the second hinge 2. After the position of the positioning assembly 3 relative to the second hinge 2 is adjusted according to the size and position relationship between the vehicle door 200 and the vehicle body 300, the locking bolt 5 is tightened so that the bolt head 501 and the positioning pin 4 are close to each other and finally abut against the second hinge 2, so that the locking bolt 5, the second hinge 2 and the positioning pin 4 are fixed to each other, thereby completing the position adjustment of the positioning assembly 3 and realizing the locking and sliding connection of the positioning assembly 3 relative to the second hinge 2. It can be understood that the cross-sectional diameters of the bolt head 501 and the positioning pin 4 are larger than the aperture of the through hole portion 202, thereby ensuring that the second hinge 2 is clamped between the bolt head 501 and the positioning pin 4, so that the locking bolt 5, the second hinge 2 and the positioning pin 4 are fixed to each other.

[0045] Furthermore, in some embodiments of the present application, the hole depth of the threaded hole 401 is greater than the axial length of the threaded portion 502. This arrangement ensures that the threaded hole 401 has a sufficient hole depth for the threaded portion 502 to be screwed in, so that the second hinge member 2 is clamped between the bolt head 501 and the positioning pin 4, so that the locking bolt 5, the second hinge member 2 and the positioning pin 4 are fixed to each other.

[0046] Further, in some embodiments of the present application, a rubber washer 6 is provided between the bolt head 501 and the second hinge part 2, and / or between the locating pin 4 and the second hinge part 2; the rubber washer 6 is sleeved on the threaded portion 502. It can be understood that the meaning of the above statement is that the rubber washer 6 can be provided alone between the bolt head 501 and the second hinge part 2, or the rubber washer 6 can be provided alone between the locating pin 4 and the second hinge part 2, or the rubber washer 6 can be provided simultaneously between the bolt head 501 and the second hinge part 2 and between the locating pin 4 and the second hinge part 2. The present application does not impose specific restrictions on the above three situations, and those skilled in the art can select the above three situations according to actual conditions. In the embodiment of the present application, the rubber washer 6 is provided between the locating pin 4 and the second hinge part 2. By providing the rubber gasket 6, the rubber gasket 6 has a high elastic deformation capacity, and can adapt to the gap between the two fasteners (such as the bolt head 501 and the second hinge 2), and when the fastening force is impacted by the outside, it can produce elastic deformation to absorb the impact force, so that the fastener remains stable. Therefore, the use of the rubber gasket 6 can effectively prevent the thread from loosening.

[0047] Furthermore, in some embodiments of the present application, the second end of the positioning pin 4 along its length direction adopts a tapered structure, and the cross-sectional diameter of the positioning pin 4 gradually decreases along the length direction of the positioning pin 4 and toward the second end of the positioning pin 4. In this way, the second end of the positioning pin 4 along its length direction is designed to be a tapered structure, and the tapered structure guides the positioning pin 4, so that the positioning pin 4 can be more smoothly inserted into the positioning hole 310 for positioning, thereby improving the assembly efficiency of the vehicle door 200 and the vehicle body 300.

[0048] The following is a detailed description of the assembly process of the vehicle door 200 in combination with the above embodiment. Figure 5-10 , specifically including the following steps:
