DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-6, the present utility model provides a technical solution: a split-type anti-compression automobile bumper, including a base plate 1. On one side of the base plate 1, two positioning blocks 11 are fixedly connected. On one side of the positioning block 11, there is a disassembly and assembly mechanism corresponding to it. On one side of the disassembly and assembly mechanism, a support plate 2 is fixedly connected. On one side of the support plate 2, a bending block 21 is slidably connected. On one side of the bending block 21, a rebound mechanism is connected. The rebound mechanism is fixedly connected to the support plate 2. At the beginning, the passengers can fix the support plate 2 and the positioning block 11 together through the disassembly and assembly mechanism to realize the fixation of the bumper. When the bumper is impacted, that is, when the bending block 21 is impacted. In the case of a small impact force, the rebound mechanism will rebound and return to its original state. In the case of a large impact force, there will be a secondary protection. By setting up a rebound mechanism, after the bumper is slightly impacted, it can automatically return to its original position under the action of the rebound force of the first spring 24, improving the durability and service life of the bumper, and reducing the inconvenience and cost caused by frequent repairs. At the same time, there is also a secondary anti-compression protection to minimize the loss and damage to the greatest extent. By setting up a disassembly and assembly mechanism, the bumper is convenient to disassemble and assemble, with simple operation. Just rotate the rotating block 33, reducing the repair time and improving the work efficiency.

[0027] The rebound mechanism includes a moving rod 22. The moving rod 22 is fixedly connected to the bending block 21. On the outer side of the moving rod 22, two supports 23 are slidably connected. The supports 23 are fixedly connected to the support plate 2. On the outer side of the moving rod 22, a U-shaped block 25 is slidably connected. On the outer side of the moving rod 22, a ring 26 is fixedly connected. On one side of the ring 26, a first spring 24 is fixedly connected. On one side of the U-shaped block 25, there is a limiting mechanism corresponding to it. When the bending block 21 is impacted, the moving rod 22 fixedly connected to it moves to the right and slides inside the two supports 23. The moving rod 22 is also slidably connected to the U-shaped block 25. At the beginning, the U-shaped block 25 is relatively stationary. At this time, the fixedly connected ring 26 has to move together. In this way, the ring 26 compresses the first spring 24. At this time, the first spring 24 has a rebound force, which pushes the U-shaped block 25 to the right at this time. However, the limiting mechanism at the bottom restricts the movement of the U-shaped block 25. When the U-shaped block 25 has enough thrust, it can push open the restriction of the limiting mechanism. At this time, the U-shaped block 25 is pushed to the other side. When there is not enough thrust, the rebound force of the first spring 24 will also send the moving rod 22 back to its original position. That is, in the case of a small impact force, the bumper can rebound, which can save the repair process.

[0028] The limiting mechanism includes a slider 28. A groove 29 is formed inside the support plate 2. The slider 28 is located inside the groove 29 and is slidably connected to the groove 29. A second spring is fixedly connected to the bottom of the slider 28, and the other end of the second spring is fixedly connected to the bottom of the groove 29. The slider 28 is slidably engaged with the U-shaped block 25. Initially, the U-shaped block 25 abuts against the slider 28, and the second spring at the bottom of the slider 28 also presses against the slider 28. In this way, the three are pressing against each other, which is a stable state. When a force is applied to the right on the U-shaped block 25, the U-shaped block 25 moves to the right, and the bottom inclined surface of the U-shaped block 25 presses the slider 28 downward. There is a certain distance between the U-shaped block 25 and the support plate 2. When the inclined surface of the U-shaped block 25 presses the slider 28 to the bottommost position, at this time the slider 28 no longer abuts against the U-shaped block 25, and the U-shaped block 25 moves to the other side. When the impact force is small, this force cannot press the slider 28 to the bottommost position, so the U-shaped block 25 cannot cross over the slider 28. When the impact force disappears, the bumper will return to its original position.

[0029] The ring 26 and the first spring 24 are both located in the middle of the U-shaped block 25. The other end of the first spring 24 is fixedly connected to the inner side of the U-shaped block 25. In this way, the ring 26 can press against the first spring 24 and then apply a force to the U-shaped block 25.

[0030] A third spring 27 is fixedly connected to one side of the support 23. The third spring 27 is sleeved outside the moving rod 22. When the impact force is relatively large, at this time the first line of defense of the U-shaped block 25 is released. At this time, the moving rod 22 continues to move to the right, and the bending block 21 moves near the third spring 27. The bending block 21 presses against the third spring 27, and the rebounding force of the third spring 27 can further reduce part of the impact force, minimizing the loss.

[0031] The disassembly and assembly mechanism includes two hollow blocks 3. The hollow blocks 3 are fixedly connected to the support plate 2. A vertical rod 31 is fixedly connected inside the hollow block 3. The top of the vertical rod 31 is connected to a rotating block 33. The bottom of the rotating block 33 is rotatably connected to a round block 32. The round block 32 and the vertical rod 31 are in sliding fit. Three corresponding blocks 34 are fixedly connected to the side of the round block 32. A short rod is fixedly connected to the middle of the corresponding block 34. One side of the short rod is rotatably connected to a rocker 35. One side of the rocker 35 is rotatably connected to a clamping block 36. Three square blocks 37 are fixedly connected to one side of the hollow block 3. A thin rod 38 is fixedly connected to the middle of the square block 37. The thin rod 38 and the clamping block 36 are in rotational connection. The clamping block 36 corresponds to the positioning block 11. When the passengers are about to install the bumper, first, align the three clamping blocks 36 with the positioning block 11. The passengers rotate the rotating block 33. The rotating block 33 will move upward. Since the rotating block 33 and the round block 32 are in rotational connection, when the rotating block 33 rotates, the round block 32 remains stationary, but the rotating block 33 will move upward. Therefore, it drives the round block 32 to move upward. In this way, the corresponding block 34 moves upward, the rocker 35 moves upward, and it pulls one end of the rotatably connected clamping block 36 upward. The clamping block 36 is supported by the thin rod 38. The thin rod 38 is equivalent to a fulcrum. The lower end of the clamping block 36 moves upward, and the other end opens outward with the thin rod 38 as the fulcrum. Similarly, it can be obtained that when the passengers rotate the rotating block 33 downward, at this time, the clamping block 36 will retract inward, and the positioning block 11 can be clamped to complete the fixation. By providing the disassembly and assembly mechanism, the bumper of the device is convenient to disassemble and replace. The bumper damaged by impact can be easily replaced. The operation is simple, which reduces the burden on the passengers.

[0032] Threads are provided at the top of the vertical rod 31. The top of the vertical rod 31 and the rotating block 33 are in threaded connection. Because of the threaded connection, when the rotating block 33 is rotated, the rotating block 33 will also move up and down by changing the rotation direction.

[0033] The connection part between the thin rod 38 and the clamping block 36 is at the middle of the clamping block 36. In this way, the thin rod 38 serves as a fulcrum better.
