Background technology

Chinese patent open file CN101289056A discloses a kind of quick-replaceable electric motor vehicle cell box, the lockable mechanism of installing on this battery case mainly is made up of latch lock, solution tapered end and drive link, wherein, separating tapered end is fixedly mounted on the front panel of battery case, the left and right sides of separating tapered end is respectively equipped with the latch lock, in separating tapered end, be provided with a jack, the latch of corresponding both sides lock is rotatablely equipped with two swing arms in the jack, and two swing arms are in transmission connection with the dead bolt that corresponding latch is locked by the hinged drive link of correspondence respectively.During use, unlocking apparatus insert to be separated the swing arm that promotes to separate in the jack of tapered end in the tapered end, and swing arm drives the dead bolt that drive link spurs two latches lock and moves the realization release to the centre simultaneously, outwards extracts battery case in the time of release again out.The locking system of installing on this battery case is when taking out battery case, because its application of force direction that promotes the release of solution tapered end is opposite with the application of force direction of extracting battery case out, therefore the operation when extracting of this battery case is very inconvenient, and the extraction of battery case is comparatively difficult.

The utility model content

The purpose of this utility model is: a kind of power battery box of being convenient to extract is provided, and the release application of force direction when solving the lockable mechanism installed on the existing power battery box because of release extracts difficult defective with the battery case that the power battery box draw-off direction causes mutually on the contrary.

The technical scheme of this power battery box is: a kind of power battery box, the push-pull lock locking apparatus of corresponding locking cooperation when connecting with battery compartment is installed at this power battery box, this push-pull lock locking apparatus comprises that guiding is assemblied in the dead bolt on the power battery box and is assemblied in solution tapered end on the power battery box along the activity of described power battery box pull direction, in this solution tapered end, be provided with along the pull direction of power battery box and extend, lockhole for the key insertion, and be provided with the stop part that cooperates for key retaining after card is fitted on the position separating tapered end, between described solution tapered end and dead bolt, also be connected with separating tapered end and be subjected to driving the linkage that the back described dead bolt of drive moves along guide direction along the external force of battery case pull direction.

Described linkage comprises swing arm, one end of swing arm is hinged on the outer wall of separating tapered end by first hinge, the other end of outer wall is hinged by second hinge and described dead bolt, described first hinge and while and described lockhole center line spatial vertical parallel with the pivot center of second hinge.

Described stop part is convexly set in lock pin on the lockhole inner hole wall at least one.

In the described lock pin guiding slidable fit pin-and-hole that correspondence is offered on the lockhole inner hole wall, lock pin is towards the inner hole wall of the outstanding lockhole in the outer end of lockhole, and be provided with for touching when inserting with key towards the Way in of lockhole in the inner of the outstanding lockhole hole wall of lock pin and cooperate inclined-plane or the cambered surface that lock pin is headed into pin-and-hole, in described pin-and-hole, also be equipped with to cooperate with inner pushing tow that lock pin is arranged in pin-and-hole and order about the snap that lock pin resets.

Be provided with described lock pin corresponding matching at the inwall of described pin-and-hole and be used for preventing that lock pin from deviating from the limit block structure of pin-and-hole.

Described pin-and-hole is for running through the through hole of separating tapered end inside and outside wall face perpendicular to the lockhole bearing of trend, and the cover plate of shutoff pin-and-hole is located fixedly to have in the aperture pin-and-hole on being positioned at a release outer wall outside, and described snap is mounted between cover plate and the lock pin.

The cylinder barrel shaped structure that described solution tapered end is established described lockhole in being, it radially convexes with the ring platform on the outer wall that is positioned at the lockhole porch, and described pin-and-hole radially is opened in the described ring platform.

Described cover plate is plugged in the rectangle jack that vertical described pin-and-hole is offered on the ring platform.

The utility model is along power battery box pull direction lockhole to be set in separating tapered end, simultaneously separate tapered end be provided for insert lockhole in and card be fitted on the stop part that the key retaining of position cooperates, when needs extract power battery box, by be inserted in the lockhole and the lock pin that cooperates with the stop part retaining along the extraction direction of battery case pulling key, key drives the solution tapered end and moves the realization release to the direction action of extracting power battery box out by linkage drive dead bolt, the application of force direction of key is identical with the extraction direction of battery case during its release, and in release, can utilize key directly power battery box to be extracted out, it is not only simple in structure, and easy to use flexibly, overcome that the release application of force direction of lockable mechanism when release causes power battery box to extract comparatively difficult defective with the power battery box draw-off direction mutually on the contrary in the prior art.
