Description

Technical Field

[0001] This utility model relates to the field of automotive bumper technology, specifically a securely installed automotive bumper. Background Technology

[0002] A car bumper (also known as a "bumper") is a safety device installed at the front and rear of a car. It is mainly used to absorb and mitigate external impact forces when the vehicle is involved in a low-speed collision or minor scratch, and to protect key components of the vehicle body (such as the engine compartment, trunk, lights, exhaust system, etc.) as well as pedestrian safety.

[0003] Existing car bumpers rely solely on bolts for fastening, which can easily loosen, make abnormal noises, or even fall off when the vehicle is bumpy or involved in a minor collision. Furthermore, some structural parts are difficult to disassemble, resulting in low maintenance efficiency. Once the main fixing point fails, the overall structural stability drops rapidly, posing a safety hazard. Therefore, we propose a car bumper with a more secure installation. Utility Model Content

[0004] The purpose of this utility model is to provide a securely installed car bumper to solve the problems mentioned in the background art, which are that existing car bumpers rely solely on bolt fastening, which are prone to loosening, abnormal noises, or even falling off when the vehicle is bumpy or in a minor collision. Furthermore, some parts of the structure are difficult to disassemble, resulting in low maintenance efficiency. Once the main fixing point fails, the overall structural stability drops rapidly, posing a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a securely installed car bumper, comprising: a bumper;

[0006] It also includes: a limiting mechanism, which is installed on the bumper and is used to limit the installation of the bumper;

[0007] The reinforcement mechanism is located at the bottom of the bumper and is used in conjunction with the limiting mechanism to reinforce the installation of the bumper.

[0008] The limiting mechanism includes two limiting plates that are fixedly connected to the inner side of the bumper. Both limiting plates have circular grooves inside, and a disc is slidably connected to the inner wall of the groove. The disc is threaded with a first internal hexagon bolt.

[0009] The disc has fixed limit blocks on both sides, and the limit plate has a limit groove inside that matches the two limit blocks.

[0010] The reinforcement mechanism includes two internal hexagonal threaded posts inside the bumper. The bottom of each of the two internal hexagonal threaded posts is fixedly connected to an internal hexagonal slot block. Four corner stabilizing tubes are provided on the outside of the internal hexagonal threaded posts. A protective cover is provided on the outside of the four corner stabilizing tubes. A rotating seat is rotatably connected to the bottom of the protective cover.

[0011] The internal hexagonal threaded column and the internal hexagonal slot block are equipped with threaded rods.

[0012] The internal hexagonal threaded column has two first grooves, and the inner walls of the two first grooves are slidably connected to first sliders. The inside of the first slider is fixedly connected to a ramp positioning block, and a spring is fixedly connected between one side of the first slider and one side of the inner wall of the first groove.

[0013] The ramp positioning block is designed with an angled end near the threaded rod.

[0014] This utility model has at least the following beneficial effects:

[0015] By setting up a limiting mechanism, the axial sliding and radial limiting of the bumper are achieved through the limiting plate within the limiting mechanism, preventing installation misalignment. The bumper can be initially installed and fixed by using the limiting plate, disc, and limiting block, which facilitates the subsequent use of the reinforcement mechanism. By setting up a reinforcement mechanism, the combination structure of the internal hexagonal threaded column and threaded rod can improve the load-bearing capacity, and the four corner stabilizing tubes wrapping the outside of the threaded rod can improve the torsional and bending resistance. The cooperation between the above structures can reduce loosening, abnormal noise, and fatigue damage, thereby reducing maintenance frequency and operating costs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 8 This utility model provides a technical solution: a securely installed car bumper, comprising: a bumper 1;

[0028] It also includes: a limiting mechanism 2, which is installed on the bumper 1 and is used to limit the installation of the bumper 1;

[0029] The reinforcement mechanism 3 is located at the bottom of the bumper 1 and is used in conjunction with the limiting mechanism 2 to reinforce the installation of the bumper 1.

[0030] The above-mentioned limit mechanism 2, through the limit plate 21 within the limit mechanism 2, achieves axial sliding and radial limiting of the bumper 1, avoiding installation misalignment. By using the limit plate 21, disc 23 and limit block 25 in cooperation, the initial installation and fixation of the bumper 1 can be completed, which facilitates the subsequent use of the reinforcement mechanism 3. By setting the reinforcement mechanism 3, the combined structure of the internal hexagonal threaded column 31 and threaded rod 36 can improve the load-bearing capacity. Furthermore, by wrapping the outside of the threaded rod 36 with the four corner stabilizing tubes 32, the torsional and bending resistance can be improved. Thus, the cooperation between the above structures can reduce loosening, abnormal noise and fatigue damage, and reduce maintenance frequency and usage costs.

[0031] The reinforcement mechanism 3 includes two internal hexagonal threaded columns 31 disposed inside the bumper 1. The bottom of each of the two internal hexagonal threaded columns 31 is fixedly connected to an internal hexagonal slot block 35. A four-corner stabilizing tube 32 is disposed on the outside of the internal hexagonal threaded column 31. A protective cover 34 is disposed on the outside of the four-corner stabilizing tube 32. A rotating seat 33 is rotatably connected to the bottom of the protective cover 34. Threaded rods 36 are disposed inside the internal hexagonal threaded columns 31 and the internal hexagonal slot block 35. Two first sliding grooves 37 are opened inside the internal hexagonal threaded column 31. A first slider 38 is slidably connected to the inner wall of each of the two first sliding grooves 37. A ramp positioning block 39 is fixedly connected inside the first slider 38. A spring 310 is fixedly connected between one side of the first slider 38 and one side of the inner wall of the first sliding groove 37.

[0032] In use, the four-corner stabilizing tube 32 is fitted onto the outside of the internal hexagonal threaded post 31, with the internal hexagonal threaded post 31 tightly against the bottom of the bumper 1. The internal hexagonal threaded post 31 and the four-corner stabilizing tube 32 are then spot-welded together. The internal hexagonal threaded post 31 is connected to the threaded connection of the vehicle bottom. The bumper 1 can then be lifted by the four-corner stabilizing tube 32. The rotating seat 33 and the protective cover 34 are then fitted onto the outside of the internal hexagonal threaded post 31. The protective cover 34 provides protection by encasing the four-corner stabilizing tube 32. The rotating seat 33 and the internal hexagonal threaded post 32 are then connected by a thread. The corner block 35 is threaded to limit the position of the protective cover 34. Then, the threaded rod 36 is inserted into the internal hexagon threaded post 31, so that the threaded rod 36 pushes the ramp positioning blocks 39 on both sides into the first slide groove 37. The moving ramp positioning blocks 39 can drive the first slider 38 to slide and compress the spring 310 in the first slide groove 37, so that the ramp positioning blocks 39 are pushed out and enter the vehicle. In this way, the reinforcement mechanism 3 can provide vertical stability to the bumper 1, thus limiting the position of the internal hexagon threaded post 31.

[0033] Example 2

[0034] like Figures 1 to 2 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is:

[0035] The limiting mechanism 2 includes two limiting plates 21 fixedly connected to the inner side of the bumper 1. The inner side of each limiting plate 21 is provided with a circular groove 22. A disc 23 is slidably connected to the inner wall of the circular groove 22. A first internal hexagon bolt 24 is threadedly connected to the inside of the disc 23. Limiting blocks 25 are fixedly connected to both sides of the disc 23. The inner side of the limiting plate 21 is provided with a limiting groove 26 that cooperates with the two limiting blocks 25.

[0036] In use, the first hex socket head cap screw 24 is used to retract the disc 23 into the circular groove 22. By inserting the two limiting plates 21 on one side of the bumper 1 into the vehicle, the first hex socket head cap screw 24 can be used to push the disc 23 into the vehicle for limiting. Then, the first hex socket head cap screw 24 is used to fix the bumper 1 in its initial position. When the disc 23 moves, it can drive the limiting blocks 25 on both sides to slide and limit within the limiting groove 26.

[0037] The end of the ramp positioning block 39 near the threaded rod 36 is designed at an angle, which ensures that the two ramp positioning blocks 39 can be moved when the threaded rod 36 is inserted.
