For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0024] Please refer to Figure 1 and Figure 2 The utility model provides an embodiment: a fork tip device, including anti -collision mounting plate 1 and anti -collision head 2, the outside installation of anti -collision head 2 has reinforcing plate 14, anti -collision mounting plate 1 is installed with linear bearing support 3, linear bearing support 3 is installed with linear bearing 6, linear bearing 6 is slidably connected with shaft 7, the outside of shaft 7 is provided with compression spring 8, anti -collision mounting plate 1, anti -collision head 2, reinforcing plate 14, linear bearing support 3, shaft 7 and compression spring 8 all adopt non -metal composite material.

[0025] Please refer to Figure 2 Screw 4 is arranged on linear bearing support 3, and linear bearing support 3 is connected with anti -collision mounting plate 1 through screw 4.

[0026] Please refer to Figure 2The front end surface of the linear bearing support 3 is fixedly connected with a proximity switch support 5, and the front end surface of the proximity switch support 5 is fixedly connected with a proximity switch 11, which is an explosion-proof proximity switch.

[0027] Please refer to Figure 2 The linear bearing support 3 is fixedly connected with a bolt 9, the top of the bolt 9 is higher than the upper surface of the linear bearing support 3, and the lower portion of the linear bearing 6 is provided with a proximity switch trigger plate 15 fixedly connected with the shaft 7.

[0028] Please refer to Figure 3 and Figure 4 The anti-collision head 2 is provided with a vertical support seat 12 and a limiting plate 13, respectively, and the anti-collision head 2 is provided with an inner hexagonal screw 10 for fixing the vertical support seat 12 and the limiting plate 13, and one end of the shaft 7 is fixedly connected with the vertical support seat 12.

[0029] Working principle: when in use, the anti-collision fork tip device uses an explosion-proof proximity switch to realize collision detection, the proximity switch 11 is a position switch that can be operated without mechanical direct contact with the moving parts, when the sensing surface of the proximity switch 11 approaches the action distance, the switch can be actuated without mechanical contact and any pressure, thereby providing a control instruction to the controller. Since the device does not use any metal material, a capacitive proximity switch is used. The explosion-proof proximity switch is a kind of proximity switch designed for safety, which is suitable for places with flammable gas and explosive dust.

[0030] As shown in the figure, the anti-collision head 2 adopts a round corner design and a composite material to prevent metal debris and sparks from being generated by collision, when the anti-collision head 2 collides with an object, the compression spring 8 will be compressed and moved backward, and the proximity switch trigger plate 15 will also move backward with the anti-collision head 2 and the movable part. At the same time, the explosion-proof proximity switch is no longer triggered, and the controller detects that the proximity switch is no longer triggered and receives a collision signal. When the collision is released, the springs on the left and right sides act to push the anti-collision head 2 forward to the proximity switch trigger distance, and the collision signal is released. The explosion-proof proximity switch is triggered under normal circumstances, and does not trigger when a collision occurs. This way is more conducive to safety, and once the proximity switch is damaged or the wire is broken, a collision signal can be sent immediately to stop the vehicle.

[0031] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
