Description of drawings
Fig. 1 is the example structure schematic diagram of catch gear of the present utility model;
Fig. 2 is the limiting stopper position enlarged drawing among Fig. 1.
The specific embodiment
The embodiment of battery box catch gear of the present utility model: such as Fig. 1, shown in Figure 2, this catch gear is used for being installed in the front panel of battery box, comprise tapered end 1, dead bolt 3 and stop gear, described tapered end 1 is in transmission connection by link gear 2 and dead bolt 3, tapered end 1 is used for being slidedly assemblied in battery box along fore-and-aft direction (being the push-and-pull direction of battery box turnover power bin), dead bolt 3 is along with tapered end 1 is flexible along left and right directions, in order to guarantee the stable of dead bolt 3, dead bolt 3 limits upper-lower position by the orienting lug 4 that is fixed on the battery box, offer the guide groove that passes for dead bolt 3 on the orienting lug 4, be fixed with the snap close (not shown) at power bin, offer the lockhole that passes for dead bolt on the snap close, when battery box pushes power bin fully, dead bolt 3 is corresponding with the lockhole of snap close, dead bolt 3 stretches into the locking that realizes battery box and power bin in the lockhole, on the contrary release.Described stop gear comprises limiting stopper 6, limiting stopper 6 cooperates by locating dowel pin 7 slide-and-guides fixing on the slotted hole offered on it and the battery box, realize that limiting stopper 6 vertically is slidedly assemblied on the battery box, offer the spacing hole of passing for dead bolt 3 on the limiting stopper 6, slide up and down in the process at limiting stopper 6,3 pairs of seasonable dead bolts 3 of spacing hole and dead bolt can pass through limiting stopper 6, otherwise can not pass through.The lower end of described limiting stopper 6 is top-loaded with stage clip 8, the other end of stage clip 8 pushes up on the permanent seat 9 that is contained on the battery box, 8 pairs of limiting stoppers 6 of stage clip apply an application force that makes progress all the time, make the spacing hole of limiting stopper 6 depart from dead bolt 3 always, before battery box did not enter power bin fully, limiting stopper 6 stoped dead bolt 3 to enter spacing hole.For conveniently when battery box enters power bin fully, dead bolt 3 can be by the spacing hole on the limiting stopper 6, the lower end of limiting stopper is connected with hauling rope 10, hauling rope 10 passes from lower to upper stage clip 8 and is connected with limiting stopper 6, the other end of hauling rope 10 is connected with push rod 11, push rod 11 is used for rotation and is assemblied in power bin, hauling rope 10 links to each other with an end of push rod 11, push in the process of power bin at battery box, the end that links to each other with hauling rope 10 that guide pillar on the battery box promotes push rod 11 rotates, and drive hauling rope 10 pulling limiting stoppers 6 and move down until battery box puts in place, this moment, the spacing hole of limiting stopper 6 was just in time corresponding with dead bolt 3.
Be connected with extension spring 5 between described dead bolt 3 and the orienting lug 4, described extension spring 5 is in extended state when tapered end 1 moves forward, extension spring 5 by with the cooperating of limiting stopper 6, prevent that dead bolt 3 is flexible back and forth.
In above-described embodiment, moving down of described limiting stopper 6 is to realize by described hauling rope 10, thereby makes the battery box rear spacing hole that puts in place corresponding with dead bolt 3, in other embodiments, also hauling rope 10 can be set, press down limiting stopper by staff and also can realize the corresponding of spacing hole and dead bolt 3.
During above-described embodiment concrete operations, push in the process of power bin at battery box, the guide pillar of battery box promotes push rod 11 and rotates, push rod 11 drives limiting stopper 6 by hauling rope 10 and moves down, when battery box puts in place, the lockhole of limiting stopper 6 is corresponding with dead bolt 3, promote tapered end 1 mobile backward, tapered end 1 drives dead bolt 3 and enters in the lockhole, realizes the locking of battery box, at this moment, extension spring 5 is in normal condition, when if tapered end 1 moves forward, extension spring 5 stretches, and dead bolt 3 is applied application force prevents that dead bolt 3 breaks away from lockholes.In the process of taking out battery box, the pulling force that overcomes extension spring 5 spurs forward tapered end 1 makes dead bolt 3 break away from lockhole, draw forward simultaneously battery box, the guide pillar of battery box is no longer to push rod 11 effects, limiting stopper 6 moves up under the effect of stage clip 8 simultaneously, so that the spacing hole of limiting stopper 6 departs from dead bolt 3, under the combined action of limiting stopper 6 and extension spring 5, make dead bolt 3 location.
