[0023] An anti-collision beam 40 is provided on one side of the buffer pad 112; the end portion 111 is connected to the anti-collision beam 40 through the buffer structure 20;

[0024] A travel switch 30 is provided on the side wall of the buffer structure 20 close to the anti-collision beam 40 ; when the anti-collision beam 40 collides, it moves toward the side of the travel switch 30 and collides with the contact; when the travel switch 30 detects a collision, the vehicle brakes and stops.

[0025] When implementing it, Figure 1 , Figure 2 As shown, the novel anti-collision structure with a travel switch is used to be installed around a vehicle, and the novel anti-collision structure with a travel switch 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, etc., 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.;

[0026] An anti-collision beam 40 is provided at one side of the buffer pad 112; the anti-collision beam 40 spans across the two support columns 11; the end 111 is connected to the anti-collision beam 40 through a buffer structure 20; the buffer structure 20 is provided between the two support columns 11;

[0027] A travel switch 30 is provided on the side wall of the buffer structure 20 near the anti-collision beam 40; when the anti-collision beam 40 collides, it moves toward the travel switch 30 and collides with the contact; when the travel switch 30 detects a collision, it triggers the vehicle to brake and stop. The travel switch 30 is connected to the vehicle controller, and the travel switch 30 transmits the detected collision signal to the vehicle controller, and the vehicle controller starts braking and stopping according to the signal; the travel switch 30 adopts an existing product, and its structure and the working principle of triggering braking and stopping are all existing technologies, which will not be repeated here;

[0028] When a minor collision occurs, the buffer structure 20 provides buffering.

[0029] 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 .

[0030] 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.

[0031] When in use, the anti-collision beam 40 and the buffer structure 20 are usually more susceptible to damage, while the mounting bracket 10, the support column 11, etc. are relatively less susceptible to damage. In this embodiment, by setting 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, by combining the buffer structure 20, the buffer pad 112 and the support column 11, the vehicle can be more effectively protected from collision. In addition, by setting two buffer structures 20 and two travel switches 30 on both sides of the anti-collision beam 40 for buffering and collision detection, the collision of the entire anti-collision beam 40 can be detected to avoid the problem of blind spot detection.

[0032] The novel anti-collision structure with a travel switch provided by the utility model includes an installation bracket 10, a support column 11, an anti-collision beam 40, a detachable end 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; and, through the travel switch 30, collisions can be detected in time and braking and stopping can be initiated, thereby improving the safety performance of the vehicle; and, the travel switch 30 is arranged on the side wall on one side of the buffer structure 20, without occupying the space in the length direction of the support column 11, so that the entire anti-collision structure can be shorter and more compact, so that the anti-collision structure can be installed in installation scenarios with limited space.

[0033] When implementing it, Figure 2 , Figure 3 As shown, the buffer structure 20 includes a tension spring 21, a first pull rod 22 and a second pull rod 23;

[0034] One end of the tension spring 21 and one end of the first pull rod 22 are connected to the end 111 along the length direction of the end 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 of the end 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 rotatably connected to the anti-collision beam 40 through the second pull rod 23; the connecting ends between the end 111 and the first pull rod 22, between the first pull rod 22 and the second pull rod 23, and between the second pull rod 23 and the anti-collision beam 40 can be rotatably connected to the axis; the structure of the rotatable connection includes but is not limited to bolt connection and axle pin connection.

[0035] like Figure 3 As shown, the travel switch 30 is arranged along the length direction of the second pull rod 23; when a collision occurs, the anti-collision beam 40 moves toward the side of the travel switch 30, and the roller contact at one end of the action rod rolls along the anti-collision beam 40 when receiving the collision pressure of the anti-collision beam 40, and the action rod rotates along the rotation center of the other end thereof, triggering the travel switch 30.

[0036] The design of combining the buffer structure 20 and the travel switch 30 provided in this embodiment has a simple structure; compared with the existing elastic buffer structure, the weight of the entire anti-collision structure is greatly reduced, and can meet the design requirements of the vehicle lightweight body.

[0037] When implementing it, Figure 1 As shown, the mounting bracket 10 is provided with a traction structure 50, and the traction structure 50 is used to facilitate traction of the faulty vehicle when a vehicle breaks down.

[0038] When implementing it, Figure 1 , Figure 2As shown, one end of the end portion 111 connected to the support column 11 is provided with a first mounting plate 12 with an L-shaped cross section; one side of the first mounting plate 12 is connected to the support column 11 by bolts, and the other side is connected to the buffer structure 20 by bolts. 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.

[0039] 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.

[0040] When implementing it, Figure 1 As 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.

[0041] In specific implementation, the end 111 can be equipped with support columns 11 of different lengths. By assembling support columns 11 of different lengths at the end 111, the versatility of the novel anti-collision structure with travel switch can be increased.

[0042] The utility model also provides a novel unmanned transport vehicle, which adopts any of the novel anti-collision structures with travel switches as described above.

[0043] 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 with a travel switch;

[0044] The lengths of the support columns 11 of the new anti-collision structure with travel switches 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.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
