[0002] With the continuous development of the automobile industry, customers and car companies have higher and higher requirements for the refinement of vehicle DTS. Especially in the assembly of the whole vehicle, due to the accuracy of the body-in-white itself, the accuracy of the left and right taillights, the accuracy of the back door, and the fluctuation of the adjustment, the accuracy and symmetry of the gap between the back door taillight and the back door light strip are difficult to guarantee. The main reason is that the existing tailgate light strip installation structure usually achieves the installation of the light strip assembly on the tailgate outer panel by setting three locating pins in the length direction of the light strip assembly (i.e. the width direction of the vehicle body). However, the three locating pins on the light strip assembly are fixed structures. Due to the long overall length of the light strip assembly, when the three locating pins are installed on the tailgate outer panel, it is easy to cause the size of the gap between the taillight and the light strip assembly and the symmetry of the gap between the taillight and the two sides of the light strip assembly to fail to meet the DTS standard of the whole vehicle, thereby affecting the customer's perceived quality. At the same time, the size of the chain link of the light strip assembly installed on the tailgate outer panel is long, which also involves the installation accuracy between the tailgate outer panel and the side, and the installation accuracy between the tailgate outer panel and the taillight. It is difficult to control the installation accuracy of the light strip assembly, resulting in the problem of low alignment between the light strip assembly and the tailgate in the width direction of the vehicle body. In addition, the existing tailgate light strip installation structure has no better repair plan. The light strip can only be replaced during repair, which has the problem of a long matching and rectification cycle and huge investment in manpower and material resources.

[0003] Therefore, it is necessary to improve the existing back door light strip installation structure to solve the above-mentioned technical defects. Utility Model Content

DETAILED DESCRIPTION

[0020] As shown in the figure, the back door light strip installation structure provided by the utility model comprises a light strip body 1 installed on the back door outer panel of the vehicle body, the light strip body 1 is provided with a positioning pin assembly on the installation side with the back door outer panel, the positioning pin assembly comprises a movable positioning pin 2 arranged in the middle section of the light strip body 1, the movable positioning pin 2 is used to adjust the installation accuracy of the light strip body 1 with the back door outer panel in the width direction of the vehicle body; Figure 1 As shown, when the light strip body 1 is installed on the back door outer panel, the installation position is pre-positioned by the positioning pin assembly first, and then the installation work is completed. However, conventional positioning pin assemblies are fixed positioning pins to enable the light strip body 1 to be positioned in the height direction of the vehicle body when installed on the back door outer panel; but in this solution, the fixed positioning pin located in the middle section of the light strip body 1 is changed to a movable positioning pin 2, wherein the movable positioning pin 2 is mainly used to adjust the installation accuracy of the light strip body 1 and the back door outer panel in the width direction of the vehicle body, so that the light strip body 1 can not only be positioned in the height direction of the vehicle body, but also can be positioned in the width direction of the vehicle body with a minimum The deviation value is installed and positioned, thereby reducing the deviation between the light strip body 1 and the back door outer panel in the width direction of the vehicle body when installed, meeting the DTS standard requirements of the whole vehicle. At the same time, there is no need to reduce the installation deviation by replacing the light strip body 1, avoiding the long matching and rectification cycle and huge investment in manpower and material resources in the later stage. For example, in this solution, first adjust the gap between the back door and the side wall to make the symmetry of the gap on both sides meet the requirements, and then check whether the gap between the taillight and the light strip body 1 meets the requirements. If not, the gap can be fine-tuned through the movable positioning pin 2 to ensure that its DTS meets the requirements and avoid the additional cost of replacing parts.

[0021] In this embodiment, the movable positioning pin 2 is an eccentric positioning pin and includes a mounting seat 201, a mounting section 202 arranged below the mounting seat 201, and a positioning section 203 arranged above the mounting seat 201. The mounting section 202 is coaxially arranged with the mounting seat 201, and the central axis of the positioning section 203 is eccentrically arranged with the central axis of the mounting seat 201; Figure 3 and Figure 4 As shown, the movable positioning pin 2 is an eccentric positioning pin structure and includes a mounting seat 201, a mounting section 202 is coaxially arranged below the mounting seat 201 and the connection with the light strip body is achieved through the mounting section 202, and a positioning section 203 is eccentrically arranged above the mounting seat 201.
