[0021] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] Reference Figure 1-4 A vehicle bumper bracket welding assembly includes a bumper bracket assembly 1: a connecting rod 2 is fixedly connected to the lower side of the bumper bracket assembly 1, a mounting plate 3 is fixedly connected to the lower end of the connecting rod 2, a buffer unit 4 is arranged on the lower side of the bumper bracket assembly 1, and when in use, the mounting plate 3 is connected to the front frame.

[0023] The buffer unit 4 includes a rotating block 401, which is fixedly connected to the lower sides of the left and right ends of the mounting plate 3, and the outer sides of the rotating blocks 401 on the left and right sides are rotatably connected to the support plates 402, and the outer sides of the lower ends of the support plates 402 on the left and right sides are rotatably connected to the rotating blocks 2 403, and the lower sides of the left and right ends of the bumper bracket assembly 1 are provided with sliding grooves 405, and the inner sides of the sliding grooves 405 are slidably connected to the slide plates 404, and the slide plates 404 are fixedly connected to the rotating blocks 2 403, and the damper 1 407 is fixedly connected between one side of the slide plate 404 and the inner wall of the sliding groove 405, and the slide plate A spring 406 is fixedly connected between the other side of 404 and the inner wall of the slide groove 405, the support plate 402 is arranged as an inclined structure, and the left and right support plates 402 are arranged as symmetrical structures. When in use, when the bumper bracket assembly 1 is subjected to external impact, the external impact force causes the bumper bracket assembly 1 to deform, so that the slide plate 404 on the slide groove 405 moves, and the slide plate 404 drives the support plate 402 to rotate, and through the damper 407 and the spring 406, the movement amplitude of the slide plate 404 is reduced, thereby reducing the impact force on the mounting plate 3 on the bumper bracket assembly 1.

[0024] The lower sides of the front and rear ends of the mounting plate 3 are fixedly connected with a rotating block three 408, the outer side of the rotating block three 408 is rotatably connected with a damper two 409, the outer side of the upper end of the damper two 409 is rotatably connected with a rotating block four 410, the rotating block four 410 is fixedly connected to the bumper bracket assembly 1, and the damper two 409 is set as an inclined structure. When in use, the damper two 409 is used to enhance the buffering effect of the mounting plate 3.

[0025] Working principle: When in use, the mounting plate 3 is supported by the left and right support plates 402. When the bumper bracket assembly 1 is deformed by external impact force, the slide plate 404 is driven to move. The impact of the impact force on the mounting plate 3 is reduced through the damper 1 407 and the spring 406, and the buffering effect on the mounting plate 3 is enhanced through the damper 2 409.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
