Description

Technical Field

[0001] This utility model relates to the field of bumpers with anti-collision protection, and more particularly to a bumper structure with anti-collision protection. Background Technology

[0002] Collision protection reduces damage caused by object collisions through physical or technical means. It is commonly used in home security, automotive protection, and industrial equipment. Its core principles include energy absorption, structural reinforcement, and active warning. Car bumpers are protective devices installed at the front and rear of a vehicle. Their main functions include absorbing collision impact, protecting the vehicle body structure and occupant safety, while also serving decorative and aerodynamic optimization purposes. Modern car bumpers are mostly made of plastic and consist of an outer panel, buffer material, and metal crossbeams.

[0003] There are still some problems in the use of existing bumper structures with anti-collision protection. Current bumper structures with anti-collision protection cannot provide multi-layer anti-collision protection for vehicles, so their anti-collision protection capability is weak. Therefore, those skilled in the art have provided a bumper structure with anti-collision protection to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a bumper structure with anti-collision protection. By using the main anti-collision protection structure, the outer bumper shell and the inner bumper shell can cooperate with each other to provide multiple anti-collision protection for the vehicle, thereby improving vehicle safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bumper structure with anti-collision protection, comprising an outer bumper shell and an inner bumper shell, wherein the inner bumper shell is provided on the upper and lower inner walls of the outer bumper shell near the front end, and a main anti-collision protection structure is fixedly connected to the front end of the inner bumper shell.

[0006] The main anti-collision protection structure includes a first buffer box, inside which a second groove is provided. A first damper is fixedly connected to both sides of the center of the front inner wall of the second groove. A first spring is spirally sleeved on the outer side of each of the two first dampers. A buffer plate is fixedly connected to the rear end face of each of the two first dampers. The rear end face of the buffer plate passes through the inner wall of the second groove and extends to the front end face of the inner bumper shell. A second buffer box is provided on both rear ends of the rear end face of the buffer plate. The rear end faces of the two second buffer boxes pass through the front end face of the inner bumper shell and extend to the rear end face of the inner bumper shell. A first groove is provided inside each of the two second buffer boxes. A second damper is fixedly connected to the center of each of the two first grooves. A second spring is spirally sleeved on the outer side of each of the two second dampers. A buffer post is fixedly connected to the rear end face of each of the two second dampers. The rear end faces of the two buffer posts are fixedly connected to the front end face of the outer bumper shell.

[0007] With the above technical solution, when a vehicle is impacted during driving, the two buffer pillars will compress the two second dampers and two second springs inside the two first grooves to complete the first step of anti-collision protection. At the same time, the two auxiliary anti-collision protection structures located inside the outer bumper shell and the inner bumper shell will also slide synchronously to assist the two second dampers and two second springs in the first step of anti-collision protection, preventing the vehicle from suffering greater damage. When the first step of anti-collision protection is insufficient, the outer bumper shell will completely adhere to the inner bumper shell. Then, the buffer plate located at the center of the front end of the inner bumper shell will begin to move. At the same time, the two bolts located inside the two moving grooves will also move towards the vehicle under the action of force. Then, the buffer plate will gradually compress the two first dampers and two first springs inside the second grooves to complete the second step of anti-collision protection.

[0008] Furthermore, an auxiliary anti-collision protection structure is fixedly connected between the outer bumper shell and the inner bumper shell. The auxiliary anti-collision protection structure includes two fixed blocks, which are respectively fixedly connected to two curved surfaces of the rear inner wall of the outer bumper shell. Rotary connecting columns are fixedly connected to the opposite ends of the two fixed blocks. Sliding rods are sleeved on the outer sides of the two rotating connecting columns. Sliding blocks are fixedly connected to the other ends of the two sliding rods. The two sliding blocks are slidably connected to the rear end face of the inner bumper shell.

[0009] Through the above technical solution, two sliding blocks are slidably connected inside two sliding grooves. Then, the other ends of two sliding rods fixedly connected to the two sliding grooves are sleeved on the outside of two rotating connecting columns on the two fixed blocks, thus completing the assembly of the device. When the vehicle is impacted during driving, the two buffer columns will compress the two second dampers and two second springs inside the two first grooves to complete the first step of anti-collision protection. At the same time, the two auxiliary anti-collision protection structures located inside the outer bumper shell and the inner bumper shell will also slide synchronously to assist the two second dampers and two second springs in the first step of anti-collision protection, preventing the vehicle from suffering greater damage.

[0010] Furthermore, the buffer plate is slidably connected to both sides of the upper and lower end faces, and the rear end faces of the four connecting blocks are fixedly connected to the front end face of the inner bumper shell. The lower end faces of the two connecting blocks at the lower end are provided with bolts, and the two bolts pass through the two connecting blocks at the lower end and extend to the upper end faces of the two connecting blocks at the upper end. Nuts are spirally sleeved on the outer side of the upper end of the two bolts.

[0011] The above technical solution facilitates the fixing of the inner bumper shell and the main anti-collision protection structure.

[0012] Furthermore, movable grooves are provided on both sides of the upper surface of the buffer plate;

[0013] The above technical solution facilitates the movement of the inner bumper shell towards the vehicle when impacted, allowing the buffer plate to move.

[0014] Furthermore, mounting openings are provided on both sides of the front end of the upper end of the first buffer box;

[0015] The above technical solution facilitates the installation of the device on vehicles.

[0016] Furthermore, sliding grooves are provided at the center of both curved sections of the rear end face of the inner bumper shell;

[0017] The above technical solution facilitates the movement of the outer bumper shell.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the bumper structure with anti-collision protection adopts a double-layer buffer of outer bumper shell and inner bumper shell. First, the outer bumper shell is used for the first step of anti-collision buffering by using two buffer pillars and internally set spring damping. When the first layer of anti-collision protection is insufficient, the outer bumper shell will squeeze the inner bumper shell. Then, the internally set buffer plate and spring damping will provide a second anti-collision protection, making the anti-collision protection effect better.

[0020] 2. In this utility model, the bumper structure with anti-collision protection has a sliding auxiliary anti-collision protection structure between the outer bumper shell and the inner bumper shell. Firstly, it can provide auxiliary support for the outer bumper shell, and secondly, when the device is subjected to external impact, it can slide according to the direction of the force to achieve the auxiliary anti-collision protection function.

The rear end face of the buffer plate 310 passes through the rear inner wall of the second groove 309 and extends to the front end face of the inner bumper shell 2. Both rear ends of the rear end face of the buffer plate 310 are provided with... The rear ends of the two second buffer boxes 305 extend through the front end of the inner bumper shell 2 to the rear end of the inner bumper shell 2. Each of the two second buffer boxes 305 has a first groove 304 inside. A second damper 308 is fixedly connected to the center of each of the two first grooves 304. A second spring 307 is spirally sleeved on the outer side of each of the two second dampers 308. A buffer post 306 is fixedly connected to the rear end of each of the two second dampers 308. The rear end of each buffer post 306 is fixedly connected to the outer bumper shell 2. When the vehicle is impacted during driving, the two buffer pillars 306 will compress the two second dampers 308 and two second springs 307 inside the two first grooves 304 to complete the first step of anti-collision protection. At the same time, the two auxiliary anti-collision protection structures 5 located inside the outer bumper shell 1 and the inner bumper shell 2 will also slide synchronously to assist the two second dampers 308 and two second springs 307 in the first step of anti-collision protection to prevent the vehicle from being damaged. When the first step of anti-collision protection is insufficient, the outer bumper shell 1 will completely fit onto the inner bumper shell 2. Then, the buffer plate 310 located at the center of the front face of the inner bumper shell 2 will begin to move. At the same time, the two bolts 8 located inside the two moving grooves 9 will also move towards the vehicle under the action of force. Then, the buffer plate 310 will gradually compress the two first dampers 302 and two first springs 303 inside the second groove 309 to complete the second step of anti-collision protection.

Sliding blocks 504 are fixedly connected to the other ends of the two sliding rods 503. The two sliding blocks 504 are slidably connected to the rear end face of the inner bumper shell 2. The two sliding blocks 504 are slidably connected inside the two sliding grooves 505. The other ends of the two sliding rods 503, which are fixedly connected to the two sliding grooves 505, are sleeved on the outside of the two rotating connecting columns 502 on the two fixed blocks 501, thus completing the assembly of the device. When the vehicle is hit during driving, the two buffer columns 306 will squeeze the two second dampers 308 and two second springs 307 inside the two first grooves 304 to complete the first step of anti-collision protection. At the same time, the two auxiliary anti-collision protection structures 5 located inside the outer bumper shell 1 and the inner bumper shell 2 will also slide synchronously to assist the two second dampers 308 and two second springs 307 in the first step of anti-collision protection, preventing the vehicle from being damaged.

[0033] like Figure 1 , 2 As shown in Figure 3, the upper and lower ends of the buffer plate 310 are slidably connected to the connecting blocks 7. The rear ends of the four connecting blocks 7 are fixedly connected to the front end of the inner bumper shell 2. The lower ends of the two connecting blocks 7 at the lower end are provided with bolts 8. The two bolts 8 pass through the two connecting blocks 7 at the lower end and extend to the upper ends of the two connecting blocks 7 at the upper end.

Then, four connecting blocks 7 are fixedly connected to the front and rear end faces of the first buffer box 301 respectively using two bolts 8 and two nuts 6. Then, the front end faces of the two buffer pillars 306 fixedly connected to the outer bumper shell 1 are fixedly connected to the rear end faces of the two second dampers 308 inside the two second buffer boxes 305. Then, the two sliding blocks 504 are slidably connected to the inside of the two sliding grooves 505. Then, the other ends of the two sliding rods 503 fixedly connected to the two sliding grooves 505 are sleeved on the outside of the two rotating connecting pillars 502 on the two fixed blocks 501, thus completing the assembly of the device.

[0038] When a vehicle is impacted during operation, the two buffer pillars 306 compress the two second dampers 308 and two second springs 307 inside the two first grooves 304 to complete the first step of collision protection. At the same time, the two auxiliary collision protection structures 5 located inside the outer bumper shell 1 and the inner bumper shell 2 will also slide synchronously to assist the two second dampers 308 and two second springs 307 in completing the first step of collision protection to prevent the vehicle from suffering significant damage. When the first step of collision protection is insufficient, the outer bumper shell 1 will completely adhere to the inner bumper shell 2. Then, the buffer plate 310 located at the center of the front end face of the inner bumper shell 2 will begin to move. At the same time, the two bolts 8 located inside the two moving grooves 9 will also move towards the vehicle under the action of force. Then, the buffer plate 310 will gradually compress the two first dampers 302 and two first springs 303 inside the second groove 309 to complete the second step of collision protection.
