Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for disconnecting the power supply in a battery-type forklift by disconnecting the connector when replacing the battery or in an emergency.

Generally, the connector that connects the battery side cable and the load side cable is fitted fairly tightly to prevent it from being accidentally pulled out due to vibrations of the vehicle or the like. Therefore, it is extremely difficult to disconnect the connector with your fingers, so the connector is normally disconnected by tilting a control lever installed near the driver's seat. is also a considerable force (usually
(10 to 15 kg), and there was also a problem that the control lever would wobble due to vehicle vibration.

An object of the present invention is to provide a power release device for a battery type forklift that can eliminate the above-mentioned conventional problems.

Hereinafter, embodiments of the present invention will be specifically described based on the drawings. First, the embodiment shown in FIG. 1 will be described. In the figure, 1 is a battery case, 2 is a battery case cover, and 3 is a flat bracket fixed to the front of the battery case 1. A fixed connector 4 on the load side is fixed to the front of this bracket 3 with a bolt. ing. A movable connector 5 on the battery side is removably fitted to the fixed connector 4 from above, and the rear surface of the movable connector 5 is slidably abutted against the front surface of the bracket 3, and a connector is provided on the front surface. It has a square-shaped engagement member 6.

Operation lever 7 for connecting and disconnecting the connector
consists of a rod portion 7a having a knob 8 at the upper end and a lever portion 7b fixed approximately horizontally to the lower part of the rod portion 7a, and the lever portion 7b is connected to the bracket 3 through a pin 9. The lever portion 7b is rotatably supported and prevented from coming off by a washer 10 and a split pin 11, and the tip of the lever portion 7b is engaged with the engaging member 6 of the movable connector 5. A torsion spring 12 is attached to the pin 9, and this torsion spring 12 has one end hooked to the bracket 3 and the other end hooked to the lever portion 7b, so that the operating lever 7 can be removed from the connector. It is biased in the direction. However, the urging force by the torsion spring 12 is set to be weaker than the force required to remove the movable connector 5, that is, the maximum removal force. Reference numeral 13 denotes a stopper pin provided on the bracket 3, which prevents the movable connector 5 from separating from the fixed connector 4 more than necessary by coming into contact with the lower end of the rod portion 7a of the operating lever 7.

The device of this embodiment is constructed as described above, and therefore, when replacing the battery or in an emergency, the user can grasp the knob 8 and tilt the operating lever 7 in the direction of the arrow shown until its lower end touches the stopper pin 13. For example, as shown by the imaginary line, as the lever portion 7b rotates, the movable connector 5 is pushed upward and removed from the fixed connector 4, but in this case, as described above, the torsion spring 12 moves in the direction of removing the connector. This allows the operator to easily disconnect the connector with relatively light force. After the separation, the operating lever 7 is operated by the torsion spring 12.
The movable connector 5 is pressed against the stopper pin 13 by the acting force of the movable connector 5, so that the movable connector 5 is held in a position separated from the fixed connector 4.

When connecting both connectors 4 and 5, move the movable connector 5 to the fixed connector 4 by tilting the operating lever 7 in the opposite direction against the torsion spring 12.
However, after fitting, the tip of the lever portion 7b is pressed against one side of the engaging member 6 by the acting force of the torsion spring 12, so it cannot be operated regardless of vehicle vibrations, etc. The rattling of the lever 7 is suppressed.

Next, in another embodiment shown in FIG. 2, the torsion spring in the previous embodiment is replaced with a tension spring 12, and the tension spring 12 is attached to the bracket 3 via an eye bolt 14. The acting force of the tension spring 12 can be adjusted as necessary.

As detailed above, the present invention uses a spring to bias the operating lever in the connector removal direction with a force weaker than the connector removal force, thereby making it easy and instantaneous to disconnect the connector using the operating lever. In addition, it is possible to maintain the disconnected state of the connector after disconnection, and when mating, it is possible to suppress rattling of the operating lever caused by vibrations of the vehicle, etc.
