The anti-collision device of the embodiment of the application performs elastic connection by arranging the elastic adjusting mechanism 3 between the first substrate 11 and the second substrate 21, on one hand, the elastic adjusting mechanism 3 can provide elastic force to the first substrate 11 and the second substrate 21, so that the first substrate 11 and the second substrate 21 have elasticity, and a certain buffering effect is provided when the second substrate 21 is impacted by an obstacle; on the other hand, the elasticity that elasticity adjustment mechanism 3 provided can be adjusted in a flexible way to can adjust foretell default, only when the impact that second base plate 21 received surpassed the default, thereby second base plate 21 can just move towards first base plate 11 and trigger limit switch 4, through so setting up, can so that this buffer stop can use in a plurality of different scenes, and its environmental suitability is strong, can realize multiple use.
This buffer stop is when practical application, and limit switch 4 can insert in the engine control circuit and the brake control circuit of vehicle, when bumping limit switch 4 and triggered, can make the engine outage flame out, and braking system starts and brakes to effectively brake the vehicle, prevent that it from continuing to advance. In this embodiment, the limit switch 4 is in a normally closed state, and is in a normally open state when triggered, so that the engine control circuit is in a power-off state, and in addition, in order to avoid that the touch external force is relieved at the moment of power-off of the engine, when the limit switch 4 is reset under the elastic force action of the elastic adjusting mechanism 3 and returns to the normally closed state, the engine is restarted due to the operation inertia, a time relay can be connected into the engine control circuit, and by using the delay action of the time relay, even if the limit switch 4 is reset instantaneously, the control circuit is still in the power-off state until the engine is shut down and completely stops operating, so that the engine cannot be restarted, the vehicle is stopped, and further protection is provided. Of course, the electrical connection mode of the limit switch 4 and the control system of the vehicle may be various, and is not limited to the above mode, and the user may perform the adaptive adjustment according to the requirement.

Wherein, as shown in fig. 7, the through hole 111 that supplies the head rod 32 to pass is provided with on the first base plate 11, and elastic deformation can take place for elastic deformation body 31, and it can do the wrench movement and the bending deformation of any direction, no matter what direction touch casing 2 received the collision force from, elastic deformation body 31's wrench movement and bending deformation all can make head rod 32 move about freely in through hole 111 to guarantee that the second base plate 21 can not have the movement of jamming towards first base plate 11 and then effectively trigger limit switch 4.
It can be understood that, the elastic adjustment mechanism 3 thus configured can adjust the distance between the first substrate 11 and the second substrate 21 by adjusting the specific installation position of the limiting member 35 on the first connecting rod 32, so as to change the compression amount of the elastic deformation body 31 and the return spring 34, thereby adjusting the elastic force provided by the elastic adjustment mechanism 3, and further adjusting the preset value.
When the preset value needs to be increased, the limiting member 35 is removed (or loosened) first, then the first substrate 11 and the second substrate 21 are made to approach each other so as to extrude the elastic deformation body 31 and the return spring 34, so that the compression amount of the elastic deformation body 31 and the return spring 34 is increased, then the limiting member 35 is mounted (or fastened) on the first connecting rod 32 so as to abut against the first substrate 11, so that the elastic deformation body 31 and the return spring 34 keep the current state, at the moment, the elastic force provided by the elastic adjusting mechanism 3 is large, that is, the second substrate 21 can move by large collision force, that is, the preset value is increased.
When the preset value needs to be reduced, the limiting member 35 is removed (or loosened) first, then the first substrate 11 and the second substrate 21 are separated from each other, so that the elastic deformation body 31 and the return spring 34 are loosened appropriately, the compression amount of the elastic deformation body 31 and the return spring 34 is reduced, and then the limiting member 35 is mounted (or fastened) on the first connecting rod 32 to abut against the first substrate 11, so that the elastic deformation body 31 and the return spring 34 keep the current state, at the moment, the elastic force provided by the elastic adjusting mechanism 3 is small, that is, the second substrate 21 can move by using a small collision force, that is, the preset value is reduced.
In the present embodiment, the elastic deformation body 31 is made of a cylindrical structure, and is made of a natural rubber material, and has ultrahigh elasticity and toughness, and can perform twisting and bending deformation in any direction. The first connecting rod 32 and the second connecting rod 33 are threaded rods, and the elastic deformation body 31 is provided with threaded holes (not shown) with two ends penetrating through. One end of the second connecting rod 33 is screwed to the screw hole of the elastic deformation body 31, and the other end can be directly screwed on the second substrate 21 to realize fixation, or directly pass through the second substrate 21 and then be connected with a nut, so as to be fixed on the second substrate 21. One end of the first connecting rod 32 is screwed to the threaded hole of the elastic deformation body 31, and the other end of the first connecting rod passes through the first substrate 11 and then is in threaded connection with the limiting part 35, and the limiting part 35 is a limiting nut. The return spring 34 can abut against the first substrate 11 through a washer, and the diameter of the washer is larger than that of the return spring 34, so as to increase the force bearing area.
As can be seen from the above description, the distance between the first substrate 11 and the second substrate 21 changes with the adjustment of the elastic adjustment mechanism 3, and in order to adapt to the change of the distance between the first substrate 11 and the second substrate 21, it is necessary to properly adjust the sensitivity of the limit switch 4 so as to ensure that it can be effectively triggered when the second substrate 21 moves towards the first substrate 11 by a preset distance, preferably, as shown in fig. 3 and 5, in this embodiment, the limit switch 4 includes a switch body 41 and a retractable actuating arm 42, and the actuating arm 42 is hinged to the switch body 41; when the second substrate 21 moves toward the first substrate 11, the actuating arm 42 rotates toward the switch body 41 to trigger the switch body 41. By arranging the telescopic action supporting arm 42, the stress distance of the action supporting arm 42 can be changed, the difficulty degree of rotation of the action supporting arm can be adjusted, and the adjustment of the sensitivity of the limit switch 4 can be realized. In addition, the switch body 41 is a main body of the limit switch 4 in the prior art, and the detailed structure and the operation principle thereof are not described herein again.
