Description

Technical Field

[0001] This utility model belongs to the field of automotive tailgate assembly technology, specifically, it relates to an automotive tailgate adjustment device. Background Technology

[0002] In the early days of the automotive industry, car assembly relied primarily on manual alignment of parts. Workers used experience and simple tools, such as calipers and locating pins, to ensure the correct placement of components on the frame or body. When installing a car door, a worker would first roughly align the door hinge with the mounting holes on the body, then continuously adjust the door's position, visually inspecting the gap between the door and the body for evenness, inserting locating pins for initial fixation, and finally tightening with bolts. This method was inefficient, and the assembly quality largely depended on the worker's skill level and work condition; the limited precision of manual alignment led to several problems.

[0003] Chinese Patent (Announcement No.: CN110834196B) discloses a door assembly auxiliary limiting device. The door assembly auxiliary limiting device can open the carrier and the limiting mechanism through the telescopic cylinder, and can be used in conjunction with the door assembly assist device to clamp the door, so that the door posture is close to the theoretical state, resulting in smaller dimensional deviations of the door during assembly.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0020] like Figure 1 As shown, a car tailgate adjustment device includes a first adjustment structure 1 and / or a second adjustment structure 2, which are disposed on the car tailgate. The first adjustment structure 1 can be used to assist in positioning the car tailgate relative to the car body roof and to the car side body, and to adjust the gaps between the car tailgate and the car body roof and between the car tailgate and the car side body. The second adjustment structure 2 can be used to assist in positioning the car tailgate relative to the car side body and to adjust the gaps between the car tailgate and the car side body. The first adjustment structure 1 and / or the second adjustment structure 2, acting alone or together, can assist in the assembly of the car door to the car body.

[0021] The first adjustment structure 1 includes a first connecting plate 101, on which a first limiting block 102 and a second limiting block 103 are provided. The first connecting plate 101 is a plate with an arc surface, and when the first connecting plate 101 is connected to the tailgate of the car, it can fit together. The first limiting block 102 is fixed to one side of the first connecting plate 101. When the first connecting plate 101 is connected to the tailgate of the car, the gap between the tailgate of the car and the roof of the car is adjusted by the cooperation between the first limiting block 102 and the car body. When the first connecting plate 101 is pushed so that the first limiting block 102 abuts against the roof of the vehicle, the gap between the tailgate and the roof of the vehicle is adjusted. The second limiting block 103 is fixed to one end of the first connecting plate 101. Through the cooperation between the second limiting block 103 and the vehicle body, the gap between the tailgate and the side of the vehicle body is adjusted. When the first connecting plate 101 is pushed so that the second limiting block 103 abuts against the side of the vehicle body, the gap between the tailgate and the side of the vehicle body is adjusted.

[0022] A pull plate 3 is provided on the first connecting plate 101, and a first threaded hole 104 is provided on the first connecting plate 101. The first threaded hole 104 is connected to the tailgate bolt. The pull plate 3 allows the first connecting plate 101 to be pulled easily. The first threaded holes 104 are equally spaced on the first connecting plate 101. The first threaded holes 104 are connected to the tailgate bolt, so that the connection between the first connecting plate 101 and the tailgate is secure.

[0023] The pull plate 3 includes a first fixing plate 301, with second fixing plates 302 connected to both ends of the first fixing plate 301. The second fixing plates 302 are connected to the first connecting plate 101. In use, the first fixing plate 301 is held by hand, and the second fixing plates 302 are used to connect the first fixing plate 301 and the first connecting plate 101. By pulling the first fixing plate 301, the first connecting plate 101 can be adjusted to adjust the assembly gap with the tailgate of the car.

[0024] The first fixing plate 301 and the second fixing plate 302 are integrally formed. The integrally formed structure can enhance the connection strength between the first fixing plate 301 and the second fixing plate 302.

[0025] At least one first limiting block 102 is provided. By setting multiple first limiting blocks 102, the gap between the car body and the car tailgate can be better adjusted.

[0026] like Figure 2 As shown, the second adjustment structure 2 includes a second connecting plate 201, one end of which is connected to a third limiting block 202. The second connecting plate 201 is connected to the rear door of the car. By moving the second connecting plate 201, the rear door of the car is moved, causing the third limiting block 202 to abut against the side body of the car, thereby limiting the gap between the rear door of the car and the side body of the car.

[0027] The second connecting plate 201 has a second threaded hole 203, which is bolted to the tailgate of the car. A push rod 4 is provided on the second connecting plate 201. By connecting the second threaded hole 203 to the tailgate of the car with bolts, the connection between the second connecting plate 201 and the tailgate of the car is made more secure. The push rod 4 can be used to push the second connecting plate 201 to the tailgate of the car to adjust the gap between the tailgate of the car and the car body.

[0028] The push rod 4 includes a third fixed rod 401, one end of which is connected to the second connecting plate 201, and the other end of which is connected to a fixed ball 402. The fixed ball 402 is connected to the second connecting plate 201 via the third fixed rod 401. In use, by holding the fixed ball 402, the third fixed rod 401 is pushed to move the second connecting plate 201 and the car tailgate, thereby adjusting the gap between the car tailgate and the car body.

[0029] At least one third limiting block 202 is provided. Providing a third limiting block 202 can better limit the gap between the car's tailgate and the car body.

[0030] The role and effect of the embodiments

[0031] Pulling the first fixing plate 301 can adjust the assembly gap between the first connecting plate 101 and the car's tailgate. When the first connecting plate is pushed so that the first limiting block 102 abuts against the car's roof, the gap between the tailgate and the roof is adjusted. The second limiting block 103 is fixed to one end of the first connecting plate 101. Through the cooperation between the second limiting block 103 and the car body, it is used to adjust the gap between the tailgate and the side of the car body. When the first connecting plate 101 is pushed so that the second limiting block 103 abuts against the side of the car body, the gap between the tailgate and the side of the car body is adjusted. Pushing the second connecting plate 201 against the tailgate with the push rod 4 causes the third limiting block 202 to abut against the side of the car body, adjusting the gap between the tailgate and the car body. This structure allows the installation of the car's tailgate to meet the car body installation requirements, making the installation of the tailgate more precise.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
