Description
Technical field
The utility model relates to fender guard field, specifically, relates to the external charge protection device of a kind of electronic a kind of fork truck.
Background technology
In the use of electri forklift, because electric weight deficiency is charged, must regular charging, during 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.For fear of this kind of accident, occur, 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 the outside that charging jack (5) and micro-switch (7) were gone up and covered to fixing base (1), 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.So be badly in need of a kind of electri forklift that is applicable to, the device that each element of fork truck electric system is protected.
Summary of the invention
1, the technical matters that invention will solve
The purpose of this utility model is to propose a kind of external charge protection device that is applicable to electri forklift, the device that 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, the technical scheme that the utility model provides is:
The external charge protection device of fork truck, comprises connector adapter plate, micro-switch adapter plate, micro-switch and connector; Described connector is arranged on the middle part of connector adapter plate, and described micro-switch adapter plate is provided with micro-switch, and described micro-switch adapter plate is arranged on an end of connector adapter plate, and connector is connected with micro-switch by micro-switch roller.
The normally closed contact of described micro-switch is connected with system control loop positive source, by the through and off of control loop positive pole, realizes the opening and closing of controlling power supply.
By charge protection device is installed in battery box, be fixed on the vehicle frame of fork truck.When needs charge, in external charger connector and the connector on connector adapter plate when inserting, thereby the contact that outside connector extruding rotation micro-switch roller touches micro-switch, micro-switch normally closed contact is often opened for and is opened, and directly the power supply of cutoff circuit, disconnects control circuit, isolate the impact of large electric current on electric elements, play a protective role, but the charge circuit of storage battery is complete, the connector on connector adapter plate is connected with storage battery by cable; When charging finishes, pull up outside connector, micro-switch roller return, open contact becomes normally closed contact, and at this moment control loop is closed, can normally work.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) by using the external charge protection device of this kind of fork truck of the present utility model to charge easily, do not need to change plug-in unit and close general supply, each element of electric system is protected.
(2) the utility model is simple in structure, easy to operate, practical.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
As shown in figures 1 and 3, the external charge protection device of a kind of fork truck, comprises connector adapter plate 1, micro-switch adapter plate 2, micro-switch 3 and connector 4; Described connector 4 is arranged on connector adapter plate 1, on described micro-switch adapter plate, 2 are provided with micro-switch 3, described micro-switch adapter plate 2 is arranged on an end of connector adapter plate 1, and connector 4 is connected with micro-switch 3 by the micro-switch roller 5 on micro-switch 3.
Described micro-switch 3 comprises micro-switch roller and microswitch component, and the normally closed contact of micro-switch 3 is connected with system control loop positive source, by the through and off of control loop positive pole, realizes the opening and closing of controlling power supply.
By charge protection device is installed in battery box, be fixed on the vehicle frame of fork truck.As shown in Figure 4, when needs charge, in external charger connector and the connector on connector adapter plate when inserting, thereby the contact that outside connector extruding rotation micro-switch roller touches micro-switch, micro-switch normally closed contact is often opened for and is opened, the power supply of direct cutoff circuit, disconnect control circuit, isolate the impact of large electric current on electric elements, play a protective role, but the charge circuit of storage battery is complete, the connector on connector adapter plate is connected with storage battery by cable; When charging finishes, pull up outside connector, micro-switch roller return, open contact becomes normally closed contact, and at this moment control loop is closed, can normally work.
