Abstract
The present invention relates to the external charge protection device of a kind of fork truck, comprise connector adapter plate, micro-switch adapter plate, micro-switch and connector; Described plug-in unit is arranged on the middle part of connector adapter plate, described micro-switch adapter plate is provided with micro-switch, described micro-switch adapter plate is arranged on an end of connector adapter plate, and connector is connected with micro-switch by the micro-switch roller on micro-switch.The invention provides a kind of external charge protection device being applicable to electri forklift, to the device that each element of fork truck electric system is protected, prevent accidental operation when charging and burn out electric elements, to play a protective role and easy to operate again.
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 electricity deficiency is charged, constantly property is charged, and the connector being connected to storage battery will be pulled up or change joint during charging, closes general supply.Electric elements on fork truck must be protected, in order to avoid cause damage to fork truck components and parts in process of charging, particularly with the fork truck of control capsule.Due to the carelessness of user, may occur misoperation phenomenon, when system energization, the storage battery directly to electri forklift charges, and causes control system to burn out.In order to avoid this kind of accident occurs, reduce loss, the external charge protection of fork truck must be used can to realize protection safely and reliably.
Through retrieval, Chinese patent CN201210029961.6, denomination of invention is: a kind of charging protection device for electric vehicle, comprise fixing base (1) and charging jacks (6), charging jacks (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 the outside covering charging jacks (5) and micro-switch (7), snap close (2) is arranged on fixing base (1) and goes up and pin 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) pushes down micro-switch (7).This application scheme solves the charging safety only having battery-driven car after battery-driven car charge power supply is broken could travel, protect battery-driven car, and is not suitable for electri forklift.So be badly in need of one to be applicable to electri forklift, to the device that each element of fork truck electric system is protected.
Summary of the invention
1, the technical matters that will solve is invented
The object of the invention is to propose a kind of external charge protection device being applicable to electri forklift, to the device that each element of fork truck electric system is protected, prevent accidental operation when charging and burn out electric elements.
2, technical scheme
For achieving the above object, technical scheme provided by the invention 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 controlling power supply.
By installing charge protection device in battery box, be fixed on the vehicle frame of fork truck.When charging is required, when in external charger connector and connector adapter plate on connector to time slotting, outside connector extrudes rotating microswitch roller thus touches the contact of micro-switch, micro-switch normally closed contact is opened for and often opens, the power supply of direct cutoff circuit, disconnect control circuit, isolation big current is on the impact of 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; At the end of charging, pull up outside connector, micro-switch roller return, open contact becomes normally closed contact, and at this moment control loop closes, and can normally work.
3, beneficial effect

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Embodiment 1
As shown in figures 1 and 3, the external charge protection device 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 controlling power supply.
By installing charge protection device in battery box, be fixed on the vehicle frame of fork truck.As shown in Figure 4, when charging is required, when in external charger connector and connector adapter plate on connector to time slotting, outside connector extrudes rotating microswitch roller thus touches the contact of micro-switch, micro-switch normally closed contact is opened for and often opens, the power supply of direct cutoff circuit, disconnect control circuit, isolation big current is on the impact of 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; At the end of charging, pull up outside connector, micro-switch roller return, open contact becomes normally closed contact, and at this moment control loop closes, and can normally work.
