The utility model has the advantages that the structure is simple, the manufacturing cost is low, and the rechargeable battery can be locked stably and reliably; moreover, the device is linked with a power switch, so that when the power switch is turned off, the linkage locking can be realized conveniently and rapidly, and the condition that a user forgets to lock the rechargeable battery because of negligence can be avoided.

Description

A kind of charging electric vehicle battery protecting apparatus

Technical field

The utility model belongs to electric automobile accessory technical field, relates to a kind of charging electric vehicle battery protecting apparatus.

Background technology

Raising along with people's living standard; the automobile that electric automobile has replaced traditional use gasoline to act as a fuel because it has environment friendly and pollution-free function gradually; in general traditional electric automobile makes things convenient for its rechargeable battery to be mounted in the outside of electric automobile in order to charge; so just given pilferage molecule opportunity; when parking electric automobile, people all need to close earlier vehicle power supply; again the rechargeable battery of electric motor car is locked afterwards; need special-purpose together program of locking; and for the user; the situation of locking is forgotten in carelessness after also probably appearing at powered-down; the rechargeable battery that has had a strong impact on electric motor car is deposited fail safe; and traditional electric automobile secondary battery protective device is generally by the locking of the realization of the control circuit in the Electronic Control Box to rechargeable battery; this technical scheme has improved anti-robber's performance to a certain extent; but be unsuitable for adopting mechanical control method to come the control of realization center, and the electronic control mode cost is higher.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, and provides a kind of simple in structure, can mechanically realize the charging electric vehicle battery protecting apparatus that rechargeable battery locking and unlocking and locking effect are good.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of charging electric vehicle battery protecting apparatus; comprise and fixing mount pad and the lock body of electric automobile frame; it is characterized in that: have on the described lock body and the corresponding keyed end of the fore shaft of rechargeable battery; described mount pad inside offers slideway; lock body is arranged in the mount pad and can slides along slideway; this protective device also comprises linkage component, and described linkage component drives the lock body slip and keyed end is inserted in the fore shaft of rechargeable battery.

The measure of taking for the optimization such scheme specifically comprises:

In above-mentioned a kind of charging electric vehicle battery protecting apparatus; described linkage component comprises STATEMENT OF FEDERALLY SPONSORED and backguy; offer the interlock passage in the described lock body; described STATEMENT OF FEDERALLY SPONSORED is arranged in the interlock passage and can be resisted against the port of interlock passage; one end of backguy is connected with STATEMENT OF FEDERALLY SPONSORED, and the other end is connected with mains switch.

In above-mentioned a kind of charging electric vehicle battery protecting apparatus; described linkage component also comprises back-moving spring; described back-moving spring one end withstands on the lock body and applies a thrust that makes lock body towards the motion of fore shaft direction, and described backguy applies a pulling force opposite with back-moving spring thrust.

Compared with prior art, advantage of the present utility model is simple in structure, low cost of manufacture, and the locking of realization rechargeable battery that can be reliable and stable, and link with mains switch owing to this device again, when the powered-down switch, can realize the interlock locking like this, convenient and swift, avoided forgetting the lock rechargeable battery because of carelessness.

Description of drawings

Fig. 1 is the structural representation that this charging electric vehicle battery protecting apparatus is in the lock state;

Fig. 2 is the structural representation that this charging electric vehicle battery protecting apparatus is in unlock state.

Among the figure, mount pad 1; Slideway 11; Lock body 2; Keyed end 21; Interlock passage 22; Linkage component 3; STATEMENT OF FEDERALLY SPONSORED 4; Backguy 5; Back-moving spring 6; Rechargeable battery 7; Fore shaft 71.

Embodiment

Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

As depicted in figs. 1 and 2; this charging electric vehicle battery protecting apparatus; comprise and fixing mount pad 1, lock body 2 and the linkage component 3 of electric automobile frame; here lock body 2 is shaft-like; have fore shaft 71 corresponding keyed ends 21 on the described lock body 2 with rechargeable battery 7; described mount pad 1 inside offers slideway 11, and lock body 2 is arranged in the mount pad 1 and can slides along slideway 11.

Linkage component 3 comprises STATEMENT OF FEDERALLY SPONSORED 4, backguy 5 and back-moving spring 6, offer interlock passage 22 in the described lock body 2, described STATEMENT OF FEDERALLY SPONSORED 4 is arranged in the interlock passage 22 and can be resisted against the port of interlock passage 22, one end of backguy 5 is connected with STATEMENT OF FEDERALLY SPONSORED 4, the other end is connected with mains switch to be implemented in mains switch closes the interlock locking, back-moving spring 6 one ends withstand on the lock body 2 and apply a thrust that makes lock body 2 towards the motion of fore shaft 71 directions, described backguy 5 apply one with the opposite pulling force of back-moving spring 6 thrusts, here mainly be to realize the locking of rechargeable batteries 7 and non-locking by backguy 5 and back-moving spring 6, under back-moving spring 6 thrust, drive lock body 2 slips and keyed end 21 is inserted in the fore shaft 71 of rechargeable batteries 7, under backguy 5 tension, make the fore shaft 71 of the keyed end 21 disengaging rechargeable batteries 7 of lock body 2.

The operation principle of this charging electric vehicle battery protecting apparatus is as follows:

When parking, user's powered-down switch, backguy 5 is moved to the released position from tightened position, and connect the STATEMENT OF FEDERALLY SPONSORED 4 corresponding pulling force that lose of backguy 5 this moment, thereby show as under the effect of back-moving spring 6 thrusts, lock body 2 is slided along rechargeable battery 7 fore shafts 71 directions, and its keyed end 21 is inserted in the fore shaft 71, with rechargeable battery 7 lockings, this moment, the user was not if use key to turn on the power switch, this rechargeable battery 7 can't take out so, thereby guarantee rechargeable battery 7 safety.

Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present utility model.
