Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model schematic diagram.
Fig. 3 is the wire drawing structural representation.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model main body is a solid of rotation, comprises locking bar 401, and locking bar 401 front ends are established dead bolt 402, and dead bolt 402 front ends are sphere shape.Establishing two ends on the locking bar 401 is the guide pad 403 on inclined-plane, establishes two relative control pilot sleeves of opening on the locking bar 401.The first control pilot sleeve 404 is located at locking bar 401 back segments, and the second control pilot sleeve 405 is located at locking bar 401 leading portions.The first control pilot sleeve 404 is established guiding link stopper 406 and the guiding groove 407 that the end is the inclined-plane along circumference.The utility model structure can illustrate by unfolded drawing.
As shown in Figure 2, the first control pilot sleeve, 404, the second control pilot sleeves 405 are launched along circumference, then can see its structure clearly.The second control pilot sleeve 405 is established guiding link stopper 408 that the end is the inclined-plane and dark guiding groove 409, shallow guiding groove 410 along circumference; Returnning spring 411 is established in locking bar 401 rear ends.
The utility model also comprises a dead bolt control device for opening.
Offer dead bolt on the dead bolt control device for opening locking bar and open control flume 420 (in Fig. 1, can see its structure clearly), specifically as shown in Figure 2, the wire drawing 421 of three ends, first end of wire drawing 421 is a control end 430, dead bolt 423 in second end 440 of wire drawing 421 connects, the 3rd end 450 of wire drawing 421 connects locking bar 401.The other end of interior dead bolt 423 inserts dead bolt and opens in the control flume 420.As shown in Figure 3, the 3rd end 450 of wire drawing 421 connects annular guideway frame 460, establishes guide runner 470 in the ring-shaped guide rail frame 460, and guide runner 470 is connected (not shown) with locking bar 401.
The locking principle is as follows:
As shown in Figure 2, upper half part represents that lock is in closed condition among Fig. 2, when dead bolt 402 is collided, under the effect of the horizontal component of active force, dead bolt 402 is moved to the left, when arriving dotted line position, the inclined-plane of guide pad 403 end faces combines with first guiding link stopper 406 inclined-planes of controlling on the pilot sleeve 404 on the locking bar 401, the component that makes progress that is produced (being running torque in lock body) promotes the lock body rotation, after turning over certain angle, after the external force left outside the dead bolt 402 disappears (guide pad 403 arrives guiding groove 407 positions), locking bar 401 slides to the right under the thrust to the right of Rear springs 411, arrive the second control pilot sleeve 405 and establish the end when being the guiding link stopper 408 on inclined-plane along circumference, the same principle identical with the front, but it is in the dark guiding groove 409 that guide pad 403 has slipped into the locking slideway, and dead bolt 402 arrives the solid line position of Fig. 2 bottom; Interior dead bolt 423 enters dead bolt and opens in the control flume 420 under the effect of spring 490.Owing to the locking reason of interior dead bolt 423, can't promote dead bolt 402 now.Lock body enters lockup state.
The principle of unblanking:
Lock to be opened, must be with pulling the control end 430 (shown in Figure 2) that moves wire drawing, guide runner 470 can not drive locking bar 401 and be moved to the left owing in the ring-shaped guide rail frame 460 LAP (guide runner 470 is provided with attachment hole 480) is arranged.Interior dead bolt 423 then under the effect of wire drawing, skids off in dead bolt unlatching control flume 420,423 pairs of locking bars of dead bolt, 401 lockings in untiing.After the stroke of guide runner 470 strokes was covered, 460 on ring-shaped guide rail frame can move, and was moved to the left thereby make guide runner 470 drive locking bar 401, unblanked.Say that exactly guide runner 470 also has one can overcome the rigidity or the flexible body that rotatablely move and be connected with locking bar 401.Same, when promoting guide runner 470, can guarantee that wire drawing control end 430 is failure to actuate.
When the utility model was used for whole folding the packing up of seat in the vehicle, when backrest moved downward, dead bolt 402 reclaimed under the effect of power, and when arriving the lockhole position, under spring 411 effects, dead bolt 402 ejects, and plays spacing and supporting effect.When needs are changed the position, open the unlock switch of lock body, in the dead bolt withdrawal lock body, the rotation backrest gets final product.Can realize such function: 1) general seat function is realized in backrest normal position and cushion normal position.2) cushion normal position and backrest level can become bed with seat, use for the occupant.Can realize such space requirement as required: 1) big and little space, top, bottom if desired, can the backrest normal position, turn on the cushion.2) up and down the space is identical if desired, and is can backrest normal, turns under the cushion; Also can turn under the backrest, turn on the cushion, pollute to avoid cushion and backrest surface.3) little and space that top is big, bottom if desired, can cushion and backrest with turning at present.
