[0030] The detection structure 30 triggers the vehicle to brake and stop when it detects that the buffer structure 20 has a buffering action.

[0031] When implementing it, Figure 1 As shown, the novel anti-collision structure is used to be installed around the vehicle, and the novel anti-collision structure includes a mounting bracket 10; two or more support columns 11 are provided on one side of the mounting bracket 10; the support column 11 is provided with a detachable end 111; the end 111 is detachably connected to the support column 11 by bolts, buckles, quick-release clamps, etc.; the end 111 is provided with a buffer pad 112; the buffer pad 112 includes but is not limited to a rubber pad, a spring, etc.;

[0032] The buffer structure 20 is disposed between the two support columns 11 , or disposed outside the two support columns 11 ;

[0033] An anti-collision beam 40 is provided at intervals on one side of the buffer pad 112; the ends 111 of two or more support columns 11 are respectively connected to the anti-collision beam 40 through a buffer structure 20; the buffer structure 20 is connected to the detection structure 30; the anti-collision beam 40 spans across the two support columns 11;

[0035] When a minor collision occurs, the buffer structure 20 provides buffering.

[0036] When a severe collision occurs, the vehicle is protected by the buffer structure 20 , the buffer pad 112 and the structure of the support column 11 .

[0037] When the anti-collision beam 40 and the buffer structure 20 are damaged, the end portion 111 and the buffer structure 20 can be disassembled and replaced, and the mounting bracket 10 and the support column 11 can still continue to use the previous ones.

[0038] When in use, the anti-collision beam 40 and the buffer structure 20 are usually more susceptible to damage, while the mounting bracket 10 and the support column 11 are relatively less susceptible to damage. In this embodiment, by arranging the anti-collision beam 40 and the buffer structure 20 at the detachable end 111, when the anti-collision beam 40 and the buffer structure 20 are damaged, they can be disassembled and replaced; and through the structure of the buffer structure 20, the buffer pad 112 and the support column 11, the vehicle can be more effectively protected from collision.

[0039] The novel anti-collision structure provided by the utility model includes an installation bracket 10, a support column 11, an anti-collision beam 40, a detachable end portion 111 and a buffer structure 20 connected thereto. When the buffer structure 20 and the anti-collision beam 40 are damaged, they can be disassembled and replaced while retaining the installation bracket 10 and the support column 11, thereby saving replacement costs and reducing waste of resources.

[0040] When implementing it, Figure 2 , Figure 3 As shown, the buffer structure 20 and the detection structure 30 are arranged between the two support columns 11; the buffer structure 20 includes a tension spring 21, a first pull rod 22 and a second pull rod 23;

[0041] One end of the tension spring 21 and one end of the first pull rod 22 are distributed along the length direction of the end portion 111 and are connected to the end portion 111; the first pull rod 22 is located on the side away from the anti-collision beam 40; the first pull rod 22 is rotatably connected to the side wall shaft of the end portion 111; the other end of the tension spring 21 is connected to the side wall of the first pull rod 22; the other end of the first pull rod 22 is connected to the anti-collision beam 40 through the second pull rod 23.

[0042] like Figure 4 As shown, the detection structure 30 includes a third pull rod 31, a fourth pull rod 32, a fifth pull rod 33, a sixth pull rod 34, an angle sensor 35, and a support plate 36;

[0043] One end of the third pull rod 31 is connected to the connecting part of the first pull rod 22 and the second pull rod 23; the other end of the third pull rod 31 is provided with a first rotating shaft 311;

[0044] One side of the support plate 36 is welded to the mounting bracket 10 or fastened by bolts; the support plate 36 is provided with an angle sensor 35 and an elongated first stroke through hole 361;

[0045] An elongated second stroke through hole 321 is provided at one end of the fourth pull rod 32 along the length direction; the second stroke through holes 321 are staggered above the first stroke through holes 361; the first rotating shaft 311 is passed through the first stroke through hole 361 and the second stroke through hole 321; the second rotating shaft 322 passes through the middle of the fourth pull rod 32 and is connected to the support plate 36;

[0046] The other end of the fourth pull rod 32 is connected to the angle sensor 35 through the fifth pull rod 33 and the sixth pull rod 34 which are rotatably connected in sequence;

[0047] Between the end 111 and the first tie rod 22, between the first tie rod 22 and the second tie rod 23 and the third tie rod 31, between the second tie rod 23 and the anti-collision beam 40, between the fourth tie rod 32 and the fifth tie rod 33, and between the fifth tie rod 33 and the sixth tie rod 34; the connecting ends of the two third tie rods 31 can be rotatably connected; the rotatably connected structure includes but is not limited to a bolt connection and an axle pin connection.

[0048] When the anti-collision beam 40 is hit, the third tie rod 31 drives the fourth tie rod 32, the fifth tie rod 33, and the sixth tie rod 34 to move, so that the sixth tie rod 34 and one end of the angle sensor 35 rotate along the angle sensor 35. When the angle sensor 35 detects that the sixth tie rod 34 rotates, the brake is triggered. The structural design combining the tension spring 21, the first tie rod 22, and the second tie rod 23 can detect the collision of the entire anti-collision beam 40, avoiding the problem of collision that cannot be detected.

[0049] Furthermore, the buffer structure 20 and the detection structure 30 provided in this embodiment are simple in structure; compared with the existing elastic buffer structure, the weight is reduced, and the requirements of vehicles with lightweight body design can be met.

The first mounting plate 12 with an L-shaped cross section can provide sufficient space for the installation of the buffer structure 20, ensuring the normal operation of the buffer structure 20.

[0052] When implementing it, Figure 1 As shown, a horizontally arranged second mounting plate 13 is provided at the top of the mounting bracket 10; the horizontally arranged second mounting plate 13 can facilitate the mounting bracket 10 to be installed at the bottom of the vehicle beam; the position of the bottom of the beam requires fewer functional modules to be accommodated and arranged than the position of the side wall of the vehicle body, thereby avoiding the problem of the installation of the mounting bracket 10 interfering with other functional modules.

[0053] When implementing it, Figure 1As shown, a reinforcement member 14 is provided between the mounting bracket 10 and the support column 11; the mounting bracket 10, the support column 11 and the reinforcement member 14 form a triangular stable structure to enhance the strength and stability of the structure.

[0054] In specific implementation, the end portion 111 can be equipped with support columns 11 of different lengths. By assembling support columns 11 of different lengths at the end portion 111, the versatility of the new anti-collision structure can be increased.

[0055] The utility model also provides a novel unmanned transport vehicle, which adopts any of the novel anti-collision structures described above.

[0056] In specific implementation, the new unmanned transport vehicle includes an unmanned vehicle body; both the front and rear ends of the beam of the unmanned vehicle body are provided with a new anti-collision structure;

[0057] The lengths of the support columns 11 of the new anti-collision structure at the front and rear ends are the same or different; the length of the support column 11 can be adjusted according to the length of the equipment installed at the front and rear ends of the unmanned vehicle body to adapt to the installation of different equipment.
