[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0042] This application proposes a hinge installation tool. Figures 1 to 7 These are some embodiments of the present application; as shown in the accompanying drawings, the Y direction is the first direction, the X direction is the second direction, the Z direction is the third direction, and the X direction, the Y direction and the Z direction are perpendicular to each other.

[0043] See also Figures 1 to 3 In some embodiments of the present application, the hinge installation tool includes a mounting frame 1, and the mounting frame 1 is provided with guide rails 2 extending along the first direction Y on opposite sides of the first direction Y, and the mounting frame 1 is used to install the hinge.

[0044] The hinge installation tool also includes a positioning assembly 3, which includes two positioning members 31 and an adjusting member 32. The two positioning members 31 are respectively slidably connected to the guide rail 2, and the adjusting member 32 is transmission-connected to the two positioning members 31 and can make the two positioning members 31 relatively close or relatively far away in the first direction Y; that is, the relative position relationship of the two positioning members 31 in the first direction Y can be adjusted and changed by the adjusting member 32.

[0045] The two positioning members 31 are symmetrically arranged along the center line of the mounting frame 1 in the first direction Y. That is, in one embodiment, when one of the positioning members 31 moves a first distance toward the center line of the mounting frame 1 in the first direction Y, the other positioning member 31 is also synchronously driven by the adjusting member 32, so that the other positioning member 31 moves a first distance toward the center line of the mounting frame 1 in the first direction Y; in another embodiment, when one of the positioning members 31 moves a second distance toward the center line of the mounting frame 1 in the first direction Y, the other positioning member 31 moves a second distance toward the center line of the mounting frame 1 in the first direction Y.

[0046] In the technical solution of the present application, a mounting frame 1 and a positioning assembly 3 located on the mounting frame 1 are provided. When the two positioning members 31 are positioned with the two taillight mounting base plates that are relatively arranged on the vehicle in the first direction Y, the positioning members 31 will slide on the guide rail 2. Under the transmission action of the adjusting member 32, the two positioning members 31 have the same movable distance of being relatively close or relatively far away on the mounting frame 1, so that the mounting frame 1 can be located in the middle position of the two taillight mounting base plates, and then the hinge is installed through the mounting frame 1. Compared with the related art in which the installation position of the hinge on the body-in-white frame is adjusted by measuring the left and right spacing, the hinge installation tool in the embodiment of the present application can automatically position the mounting frame 1 in the middle position of the taillight mounting base plate through the positioning assembly 3, so that the hinge can be quickly installed and the difficulty of installing the hinge on the body-in-white frame of the car can be reduced.

[0047] In some embodiments of the present application, the adjusting member 32 includes a first connecting member 321 and two second connecting members 322. The first connecting member 321 is rotatably mounted on the mounting frame 1, and the rotation axis of the first connecting member 321 extends along the second direction X. The rotation axis of the first connecting member 321 intersects with the center line of the mounting frame 1 in the first direction Y. Each second connecting member 322 is respectively connected to the first connecting member 321 and a positioning member 31. That is, in this embodiment, the second connecting member 322 is connected to the first connecting member 321, and when the first connecting member 321 is driven, the positioning member 31 can be driven to move on the guide rail 2.

[0048] Among them, since the rotation axis of the first connecting member 321 intersects with the center line of the mounting frame 1 in the first direction Y, that is, the first connecting member 321 is rotatably installed in the middle position of the mounting frame 1, and the sizes of the two second connecting members 322 are consistent, the first connecting member 321 can drive the two positioning members 31 to move towards or away from the first connecting member 321 at the same time when it rotates, so that when the two positioning members 31 are installed on the taillight mounting base plates, the mounting frame 1 can be located in the middle position of the two taillight mounting base plates.

[0049] In one embodiment, the first connecting member 321 and the second connecting member 322 may be connected in a gear and rack transmission manner; in another embodiment, the first connecting member 321 and the second connecting member 322 may be connected in a rotational cooperation between a turntable and a guide rod.

[0050] In some embodiments of the present application, the second connecting member 322 includes a connecting rod 4, and the two ends of the connecting rod 4 are rotatably mounted on the positioning member 31 and the first connecting member 321. That is, in this embodiment, when the two positioning members 31 are mounted on the two taillight mounting base plates, the position of the positioning member 31 on the guide rail 2 will be offset according to the different relative distances between the mounting frame 1 and the two taillight mounting base plates in the first direction Y, thereby driving the connecting rod 4 to move. However, under the action of the first connecting member 321 located at the other end of the connecting rod 4, the first connecting member 321 is always located at the center position of the two positioning members 31 in the first direction Y, so that the mounting frame 1 connected to the first positioning member 31 can be located in the middle position of the two taillight mounting base plates, so as to realize the automatic adjustment of the position of the mounting frame 1 on the vehicle body, thereby realizing the rapid installation of the hinge and reducing the difficulty of installing the hinge on the white body frame of the automobile.

[0051] In some embodiments of the present application, the shape of the first connecting member 321 on the plane where the first direction Y and the third direction Z are located is Z-shaped, and the two ends of the first connecting member 321 are respectively rotatably connected to the two connecting rods 4, and the vertical distances from the connection points of the two connecting rods 4 and the first connecting member 321 to the rotation axis of the first connecting member 321 are equal.
