DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0024] like Figures 1 to 5 As shown, a car bumper with a positioning and installation function comprises a bumper mounting frame 1, and a bumper positioning and installation component 4 and an anti-collision buffer component 5 installed on the bumper mounting frame 1;

[0025] The bumper positioning and mounting assembly 4 includes a limiting slot 403, which is provided on the left and right sides of the bumper mounting frame 1, and a through hole 401 is provided on the left and right sides of the limiting slot 403. Two groups of return springs 405 are fixedly installed inside the limiting slot 403, and a metal spring 404 is attached to one end of the return spring 405, and a connecting rod 402 is fixedly connected to one side of the metal spring 404. When in use, the metal spring 404 at one end of the automobile bumper body 2 is inserted into the limiting slot 403 on the surface of the bumper mounting frame 1, so that the metal spring 404 passes through the through hole 401, ensuring that the metal spring 404 is tightly attached to the return spring 405, and the assembly of the automobile bumper body 2 can be completed. Embodiment 2

[0026] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0027] The other end of the connecting rod 402 is fixedly mounted with the automobile bumper body 2, and the automobile bumper body 2 forms a clamping structure with the limiting slot 403 through the connecting rod 402 and the metal spring 404; this arrangement allows the automobile bumper body 2 to be quickly and accurately installed on the bumper mounting frame 1 without the need for complicated tools and steps, thereby improving the installation efficiency.

[0028] The anti-collision buffer component 5 includes a mounting base plate 504, which is fixedly mounted on the bottom of the bumper mounting frame 1. Two groups of mounting base plates 504 are provided, and buffer bins 501 are fixedly mounted on the surfaces of the two groups of mounting base plates 504. The setting of the anti-collision buffer component 5 effectively improves the anti-collision buffer performance and reduces the damage to the vehicle and passengers caused by the collision.

[0029] A buffer spring 502 and a damper are fixedly installed inside the buffer bin 501, and a piston rod 503 is slidably installed on one side of the buffer bin 501; the piston rod 503 slides in the buffer bin 501, and the buffer spring 502 and the damper work together to further absorb and mitigate collision energy. Embodiment 3

[0030] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0031] The other end of the piston rod 503 is fixedly connected to a buffer bracket 505, and an anti-collision buffer plate 506 is fixedly installed on the surface of the buffer bracket 505; when the vehicle collides, the automobile bumper body 2 and the anti-collision buffer plate 506 are impacted first, and at the same time, the polyurethane anti-collision layer 507, the foamed polypropylene anti-collision layer 508 and the rubber anti-collision layer 509 are deformed in turn to absorb part of the collision energy.

[0032] The anti-collision buffer plate 506 includes a polyurethane anti-collision layer 507, which is bonded to the buffer bracket 505. The surface of the polyurethane anti-collision layer 507 is bonded with a foamed polypropylene anti-collision layer 508, and the surface of the foamed polypropylene anti-collision layer 508 is bonded with a rubber anti-collision layer 509. The anti-collision buffer plate 506 is made of lightweight materials such as polyurethane, foamed polypropylene, etc., which not only ensures the anti-collision effect, but also reduces the overall weight, which is beneficial to reducing vehicle fuel consumption and improving driving stability.

[0033] The surface of the bumper mounting frame 1 is fixedly mounted with reinforcing ribs 3, and two groups of reinforcing ribs 3 are provided; the provision of the reinforcing ribs 3 enhances the structural stability of the bumper mounting frame 1, enabling it to withstand greater impact force without being easily deformed or damaged.

[0034] Working principle: When using the automobile bumper with positioning and installation function, first, fix the bumper mounting frame 1 at a predetermined position of the automobile body, and insert the metal spring piece 404 at one end of the automobile bumper body 2 into the interior of the limiting card groove 403 on the surface of the bumper mounting frame 1 through the provided bumper positioning and installation component 4, so that the metal spring piece 404 passes through the through hole 401, and ensures that the metal spring piece 404 and the return spring 405 fit tightly, and the assembly of the automobile bumper body 2 can be completed. When disassembling, it is only necessary to press the metal spring piece 404 at the same time. Under the elastic force of the return spring 405, the metal spring piece 404 and the automobile bumper body 2 can be automatically popped out. This setting enables the automobile bumper body 2 to be quickly and accurately installed on the bumper mounting frame 1, without the need for complicated tools and steps, thereby improving the installation efficiency and improving the existing automobile bumper. The bumper and the car body cannot be positioned and installed during installation, and it is often necessary to install the bumper during the bumper installation process. Several people need to cooperate with each other to fix the bumper, which wastes human resources. Through the anti-collision buffer component 5, when the vehicle collides, the automobile bumper body 2 and the anti-collision buffer plate 506 are impacted first, and at the same time, the polyurethane anti-collision layer 507, the foamed polypropylene anti-collision layer 508 and the rubber anti-collision layer 509 are deformed in turn to absorb part of the collision energy. Subsequently, the piston rod 503 slides in the buffer chamber 501, and the buffer spring 502 and the damper work together to further absorb and slow down the collision energy. This arrangement effectively improves the anti-collision buffer performance and reduces the damage to the vehicle and occupants caused by the collision. At the same time, the anti-collision buffer plate 506 is made of lightweight materials such as polyurethane, foamed polypropylene, etc., which not only ensures the anti-collision effect, but also reduces the overall weight, which is beneficial to reducing vehicle fuel consumption and improving driving stability. The arrangement of the reinforcing ribs 3 enhances the structural stability of the bumper mounting frame 1, so that it can withstand greater impact force without being easily deformed or damaged.
