[embodiment]
Below in conjunction with accompanying drawing and embodiment the battery case access device is done further and to be explained.
As depicted in figs. 1 and 2, the battery case access device comprises: be fixed on counterpart 310, the axle collar 320, return spring 330 on the battery case 10, be fixed on actuator 340, latch structure 350 and elastic component 360 on the push-pull mechanism 20.
As Fig. 3~counterpart 310 shown in Figure 7 comprised the fixed part 312 of fixation, the auxiliary section 314 that cooperates with actuator 340 and be connected fixed part 312 and the column structure 316 of auxiliary section 314.The axle collar 320 is enclosed within on the column structure 316, and return spring 330 is enclosed within on the column structure 316, and return spring 330 1 ends link to each other with the axle collar 320, and the other end links to each other with auxiliary section 314.When actuator 340 separated with counterpart 310, return spring 330 was stretched earlier, is compressed then.
Fixed part 312 is fixed on the battery case 10 through screw 313.Auxiliary section 314 is a curved-surface structure 318 with actuator 340 forward surfaces, and latch structure 350 has the ramp structure 352 that cooperates with curved-surface structure 318.
This curved-surface structure that cooperatively interacts 318 and ramp structure 352 make latch structure 350 with can better slide after auxiliary section 314 contacts.
Auxiliary section 314 has sunk structure 319 (consulting Fig. 7) with the axle collar 320 forward surfaces, and the axle collar 320 has the bulge-structure 322 (consulting Fig. 7) that matees with sunk structure 319 with auxiliary section 314 forward surfaces.
This sunk structure that cooperatively interacts 319 and bulge-structure 322 make the axle collar 320 and better driving fit of auxiliary section 318 (consulting Fig. 7); Sunk structure 319 can also well block latch structure 350 simultaneously.
In other embodiment, return spring 330 1 ends link to each other with the axle collar 320, and the other end can link to each other with fixed part 312 or link to each other with battery case 10, and in this case, when actuator 340 separated with counterpart 310, return spring 330 was compressed earlier, is stretched then; The effect of return spring 330 is in order to make the axle collar 320 have restoring force, after the axle collar 320 is moved, can be returned to initial condition and to get final product.
Actuator 340 is a U type column, and both ends 342 are respectively arranged with 344, two elastic components 360 of two draw-in grooves and are arranged in the draw-in groove 344 and with latch structure 350 and link to each other, and latch structure 350 elastic components 360 stretch in draw-in groove 344.
Auxiliary section 314 can be stretched in the U-shaped opening of actuator 340 latch structure 350 is compressed into draw-in groove 344, and after passing the line of two latch structures 350 in auxiliary section 314, latch structure 350 ejects and blocks auxiliary section 314, makes actuator 340 and counterpart 310 articulate.
Elastic component 360 is a spring in the present embodiment, and latch structure 350 is a metallic pin; In other embodiment, elastic component 360 also can be other elastic components such as elastomeric pad, and elastic component 360 maintenance latch structures 350 have restoring force and get final product.
Below in conjunction with Fig. 3~Fig. 7; The battery case access device is accomplished push-pull mechanism 20 to be described with being connected with separating process of battery case 10; Fig. 3~Fig. 7 shows battery case access device articulating and separate through actuator 340 and counterpart 310; Accomplish push-pull mechanism 20 and be connected from being separated to, again from being connected to separating process with battery case 10.
When push-pull mechanism 20 takes out battery case 10 from the battery case storehouse; At first push-pull mechanism 20 drives actuators 340 and moves to battery case 10, when the latch structure on the actuator 340 350 when the auxiliary section 314 of counterpart 310 on being installed in battery case 10 contacts, latch structure 350 is engaged portion 314 and pushes up back in the draw-in groove 344; Actuator 340 continues to move; Cross the line of two latch structures 350 in auxiliary section 314 after, latch structure 350 ejects under the effect of elastic component 360, and latch structure 350 blocks with auxiliary section 314; Actuator 340 articulates with counterpart 310, and push-pull mechanism 20 is connected with battery case 10.Push-pull mechanism 20 is regained, and this moment, actuator 340 was connected with counterpart 310, cooperates drive battery case 10 to move through actuator 340 and counterpart 310, from the battery case storehouse, takes out battery case 10.
When push-pull mechanism 20 deposited battery case 10 in the battery case storehouse, push-pull mechanism 20 drove actuator 340 and moves to battery case 10 directions, and the latch structure 350 on the actuator 340 contacts with the axle collar 320; Return spring 330 is stretched; Latch structure 350 is pushed up back in the draw-in groove 344 by the axle collar 320, and actuator 340 continues to move, and latch structure 350 ejects under the effect of elastic component 360; Actuator 340 contacts with fixed part 312, and battery case 10 is pushed the battery case storehouse.After battery case 10 put in place, push-pull mechanism 20 drove actuator 340 and regains, and actuator 340 drives the axle collar 320 to moving away from battery case 10 directions through latch structure 350, and return spring 330 is compressed.The axle collar 320 move to auxiliary section 314 butts after; The axle collar 320 gets up simultaneously through the sunk structure 319 that cooperatively interacts with bulge-structure 322 driving fits with auxiliary section 314, and the axle collar 320 stops to move; Actuator 340 continues to move; Latch structure 350 is pushed up back in the draw-in groove 344 by the axle collar 320, and actuator 340 separates with counterpart 310.Latch structure 350 ejects under the effect of elastic component 360, and the axle collar 320 is got back to original position under the effect of return spring 330.Push-pull mechanism 20 separates with battery case 10, and battery case 10 is accomplished and deposited.
This battery case access device is simple in structure, and the action matching step is less, and the reliability of equipment is higher, has a good application prospect.
The above embodiment has only expressed one or more execution modes of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
