Technical Field

[0001] The utility model relates to the technical field of forklift robots, in particular to a forklift and a cargo fork collision plate mechanism thereof. Background Art

[0002] In the existing technology, most fork striker mechanisms are welded to the forks, requiring numerous additional parts, making installation complex and impractical. Some striker mechanisms, achieving the same function, are mounted between the two forks on the fork carriage. These striker mechanisms often require additional mounting brackets on the fork carriage to accommodate the striker and detection switch, resulting in a complex installation structure. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide a forklift and a fork striker mechanism thereof, which have a simple structure and can reduce the cost of parts processing and manpower assembly.

[0004] A forklift fork striker mechanism is installed on the fork and includes a striker and a trigger switch. The upper end of the striker is rotatably connected to the vertical portion of the fork via a pin shaft. The striker includes a striker portion protruding from the vertical plane of the fork. The trigger switch is fixed to the fork and located behind the striker portion of the striker. The striker can switch between a first position and a second position around the pin shaft, and at the same time, the striker drives the trigger switch to switch between an on and off state.

[0005] Preferably, a return spring is provided at the connection between the striker plate and the fork.

[0006] Preferably, the trigger switch includes a trigger rod, which is mechanically linked to the collision portion of the collision plate, and the on-off state of the trigger switch is switched by the trigger rod.

[0007] Preferably, a weight-reducing hole is provided on the impact plate.

[0008] Preferably, the striker mechanism is rotatably fixed to the fork via a pin, and the trigger switch is fixed to the fork via at least two bolts.

[0009] A forklift comprises the fork striker mechanism of the forklift described in any one of the above items.

[0010] Since the present application adopts the above-mentioned solution, the striker plate and the trigger switch can be directly installed on the fork respectively, and there is no need to set up additional components for fixing the striker plate and the trigger switch on the mast mechanism; the installation of the striker mechanism can be completed through at least 3-4 connecting parts, which reduces the cost of parts processing and manual assembly, and greatly improves the speed of future assembly, inspection and maintenance, greatly reduces the cost of after-sales, and greatly improves work efficiency.

[0016] The embodiments of the present utility model are described in detail below.

[0017] like Figure 1 As shown, this embodiment provides a striker mechanism of a forklift robot, wherein the striker mechanism 3 is mounted on the fork 242 and is used to detect whether the fork 242 has picked up the goods in place. The striker mechanism 3 in this embodiment includes a striker and a trigger switch 32, wherein the upper end of the striker is rotatably connected to the vertical portion of the fork 242 via a pin shaft, and the striker includes a striker portion protruding from the vertical plane of the fork 242, and the trigger switch 32 is located at the rear side of the striker portion of the striker and is mechanically linked to the striker portion. The striker can be switched between a first position and a second position around the pin shaft, and the trigger switch 32 is switched between an on and off state. The distance between the distal end of the striker portion and the vertical portion of the fork 242 is larger in the first position relative to the second position, so that whether the goods are picked up in place on the fork 242 can be determined by the different states of the trigger switch 32.

[0018] As a preferred solution, a return spring is provided at the connection between the striker plate and the fork 242, so that the striker plate can automatically return to the first position from the second position after the external force is removed.

[0019] The striker mechanism 3 in this embodiment is arranged as described above, and the striker and the trigger switch 32 can be directly installed on the fork 242 respectively. There is no need to set additional components on the gantry mechanism 2 to fix the striker and the trigger switch 32. In one embodiment, the striker is fixed to the fork 242 by a pin shaft, and the trigger switch 32 is fixed to the fork 242 by two screws. The installation of the mechanism can be completed by three connecting parts, and the connection method is simple.

[0020] Furthermore, the trigger switch 32 in this embodiment is a mechanical switch, which includes a trigger rod 321. The trigger rod 321 is linked to the collision portion of the collision plate, and the trigger switch 32 is switched on and off by the trigger rod 321. The trigger switch 32 in this embodiment is triggered by a mechanical switch, and the trigger structure is accurate and reliable.

[0021] In a preferred embodiment, a weight-reducing hole 311 is provided on the striker plate. By providing the weight-reducing hole 311 , the striker plate's own weight is reduced, and the striker plate can be triggered more easily, which is beneficial to improving the sensitivity of the striker plate mechanism 3 .

[0022] And the above-mentioned striker mechanism 3 is first installed on the fork 242 to complete pre-installation, and then the fork 242 assembly is installed on the fork 242, which is beneficial to improving the assembly efficiency of the forklift robot.

[0023] Another embodiment of the present application provides a forklift having the above-mentioned striker mechanism, which also has the above-mentioned advantages.

[0024] The forklift in this embodiment is controlled as follows: when there is no foreign object on the fork in contact with the striker, the striker is in the first position. Figure 2 As shown, the trigger switch is in the off state at this time; when the cargo on the fork touches the collision plate, the collision part of the collision plate first contacts the cargo. If the fork continues to move forward, the cargo on the fork will drive the collision part to switch from the first position to the second position. At this time, the trigger switch switches to the on state, indicating that the cargo is in place and the fork cannot move forward any further, so the fork is controlled to stop; after the cargo on the fork is removed, the collision plate returns to the first position under the restoring force of the reset spring, and at the same time drives the trigger switch to switch to the off state.

[0025] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
