[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] To address the technical problems of existing anti-collision panels being prone to permanent deformation and having a short service life after minor impacts, this invention provides an anti-collision device that can absorb the impact force after a minor impact and convert the impact force into the power to restore the device to its original shape.

[0028] Please see Figures 1-4 , Figures 1-4 An anti-collision device according to one embodiment of the present invention includes a connecting seat 1 and at least one anti-collision mechanism 2 installed on the connecting seat 1. The anti-collision mechanism 2 includes a buffer member 21 and a first anti-collision member 22. The buffer member 21 is installed on the connecting seat 1 and connected to the first anti-collision member 22. A buffer gap is formed between the first anti-collision member 22 and the connecting seat 1. When the first anti-collision member 22 is impacted by an external force, the first anti-collision member 22 can move toward the connecting seat 1 and squeeze the buffer member 21. The buffer member 21 can reduce the impact force on the first anti-collision member 22 and drive the first anti-collision member 22 to reset.

[0029] In actual use, the connecting seat 1 is fixed in the preset position. When the vehicle slightly impacts the first anti-collision member 22, it will drive the first anti-collision member 22 to approach the connecting seat 1. The buffer member 21 can convert the external force on the first anti-collision member 22 into its own power. After the external impact force is removed, the buffer member 21 can drive the first anti-collision member 22 to reset through its own power, so as to extend the service life of the anti-collision device.

[0030] It should be noted that, based on the above scheme, the buffer 21 includes a sleeve 211, a spring 212, and a connecting part 213. The sleeve 211 is installed on the connecting seat 1, the spring 212 is disposed inside the sleeve 211, one end of the connecting part 213 slides through the sleeve 211 and abuts against the spring 212, and the other end of the connecting part 213 is connected to the first anti-collision member 22. When the first anti-collision member 22 moves toward the connecting seat 1, the connecting part 213 can compress the spring 212.

[0031] Understandably, when the first anti-collision member 22 moves toward the connecting seat 1, the connecting part 213 compresses the spring 212. After the spring 212 is compressed, it can store force. When the external force disappears, the spring 212 can release the elastic force, driving the first anti-collision member 22 away from the connecting seat 1, so that the first anti-collision member 22 can move to the initial position.

[0032] It should be noted that, in one embodiment, the connecting part 213 includes a guide rod 2131 and a pressure block 2132. One end of the guide rod 2131 is connected to the first anti-collision member 22, and the other end of the guide rod 2131 passes through the sleeve 211 and is fixedly connected to the pressure block 2132. The pressure block 2132 abuts against the spring 212, and the pressure block 2132 can restrict the guide rod 2131 from moving out of the sleeve 211.

[0033] Furthermore, in one embodiment, the connecting part 213 further includes a stop block 2133 and a locking nut 2134. One end of the guide rod 2131 is provided with an external thread, and the stop block 2133 is fixed on the guide rod 2131. The first anti-collision member 22 is provided with a first through hole. When one end of the guide rod 2131 passes through the first through hole, the stop block 2133 can abut against one side of the first anti-collision member 22, and the locking nut 2134 is screwed into the external thread and can abut against the other side of the first anti-collision member 22.

[0034] It should be noted that the first anti-collision member 22 is not limited to a specific structure. In this specific embodiment, the first anti-collision member 22 includes a first arc-shaped plate, a first through hole is provided on the first arc-shaped plate, and the arc-shaped convex surface of the first arc-shaped plate faces away from the connecting seat.

[0035] Understandably, when the first arc-shaped plate is impacted and deformed significantly, it can be separated from the external thread of the guide rod 2131 by rotating the locking nut 2134, making it convenient for maintenance personnel to replace the first arc-shaped plate.

[0036] Based on the above scheme, in order to further improve the anti-collision performance, specifically, the anti-collision mechanism 2 also includes a second anti-collision member 23. The second anti-collision member 23 includes a second arc-shaped plate, which is installed on the connecting seat 1 and is located between the connecting seat 1 and the first arc-shaped plate. The arc-shaped convex surface of the second arc-shaped plate faces away from the connecting seat. A second through hole is opened on the second arc-shaped plate, and the sleeve 211 passes through the second through hole.

[0037] In addition, the second arc-shaped plate is provided with limiting blocks on both sides, and the first arc-shaped plate is provided with limiting grooves on both sides that cooperate with the limiting blocks. Specifically, the two limiting blocks correspond to the two limiting grooves respectively. When the first arc-shaped plate is impacted by an external force, the two limiting blocks can slide into the limiting grooves.

[0038] It should be noted that, in one embodiment, at least one locking mechanism 3 is also installed on the connecting seat 1. The locking mechanism 3 and the anti-collision mechanism 2 are respectively located on opposite end faces of the connecting seat 1. The locking mechanism 3 is used to fix the connecting seat 1 in a preset position.

[0039] Specifically, the locking mechanism 3 includes two side plates 31, a first clamping block 32, a second clamping block 33, and two locking members 34. The two side plates 31 are installed on the connecting seat 1 at intervals. The first clamping block 32 is fixed between the two side plates 31. The second clamping block 33 is detachably connected to the first clamping block 32 via the two locking members, and the first clamping block 32 and the second clamping block 33 can form a clamping space by enclosing each other.

[0040] It is understandable that the clamping space can be either circular or square. A circular clamping space facilitates fixed connection with post-shaped guardrails, while a square clamping space facilitates fixed connection with panel-shaped guardrails.

[0041] It should be noted that, in one embodiment, the first clamping block 32 is provided with a first through hole on both sides of the first clamping block 32, and the second clamping block 33 is provided with a second through hole on both sides of the second clamping block 33; the locking member 34 includes a locking bolt 341 and a locking nut 342, the locking bolt 341 is inserted through the first through hole and the second through hole and is screwed into the locking nut 342 respectively.

[0042] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
