Abstract
The invention relates to an external charging protection device for a forklift. The external charging protection device comprises a connector fixing plate, a micro-switch fixing plate, a micro-switch and a connector, wherein the connector is arranged on the middle part of the connector fixing plate; the micro-switch is arranged on the micro-switch fixing plate; the micro-switch fixing plate is arranged on one end part of the connector fixing plate; the connector is connected with the micro-switch through a micro-switch roller on the micro-switch. By adopting the external charging protection device suitable for an electric forklift, each element of a forklift electric system is protected, so that electric elements are prevented from being burned due to accidental operation during charging. The external charging protection device plays a role in protection, and is convenient to operate.
Description
Technical field
The present invention relates to fender guard field, specifically, relate to the external charge protection device of a kind of electri forklift.
Background technology
In the use of electri forklift, because electric weight deficiency is charged, must regular charging, when charging, joint will be pulled up or changed to the connector that is connected in storage battery, close general supply.Must protect the electric elements on fork truck, in order to avoid fork truck components and parts are caused to damage in process of charging, particularly with the fork truck of control capsule.Due to user's carelessness, may there is misoperation phenomenon, in the situation that system is switched on, directly give the storage battery charging of electri forklift, cause control system to burn out.Occur for fear of this kind of accident, reduce loss, must use the external charge protection of fork truck can realize safely and reliably protection.
Through retrieval, Chinese patent CN 201210029961.6, denomination of invention is: a kind of charging protection device for electric vehicle, comprise fixing base (1) and charging jack (6), charging jack (5) is arranged on fixing base (1), also comprise snap close (2), jack protective cover (3) and micro-switch (7), micro-switch (7) is arranged on fixing base (1), jack protective cover (3) one end is arranged on fixing base (1) and goes up and cover charging jack (5) and the outside of micro-switch (7), snap close (2) is arranged on fixing base (1) above and pins mutually with the movable end of jack protective cover (3), when jack protective cover (3) locks mutually with snap close (2), jack protective cover (3) is pushed down micro-switch (7).This application scheme has solved the charging safety of only having battery-driven car after battery-driven car charge power supply is broken just can travel, protect battery-driven car, and is not suitable for electri forklift.Be applicable to electri forklift, the device that the each element of fork truck electric system is protected so be badly in need of one.
Summary of the invention
1, the technical matters that invention will solve
The object of the invention is to propose a kind of external charge protection device that is applicable to electri forklift, the device that the each element of fork truck electric system is protected, the accidental operation while preventing from charging and burn out electric elements.
2, technical scheme
For achieving the above object, technical scheme provided by the invention is:
