Detailed description of the invention
The present embodiment relates to a kind of seat cushion release mechanism, and as shown in Figure 1, it mainly comprises two parts, first elastic rib 1, and it two is snap closes 2.Wherein, elastic rib 1 connection is arranged on the rear of cushion 200, and snap close 2 is fixed on vehicle floor 100, as shown in Figure 2, lock groove 201 is provided with at the middle part of snap close 2, above lock groove 201, also be the top of snap close 2, be fixed with prominent cap 202, prominent cap 202 is provided with the inclined-plane 203 tilted obliquely, in order to realize being connected of snap close 2 and vehicle floor 100, being fixed with the supporting seat 205 with bolt hole 204 in the bottom of snap close 2, snap close 2 can being fixedly connected on vehicle floor 100 by not shown bolt.The setting of lock groove 201, the elastic rib 1 under state of nature can be made to snap in lock groove 201, and elastic rib 1 is subject to the barrier effect of the prominent cap 202 at snap close 2 top, can limit the latched position of cushion 200, and its lock-out state as shown in Figure 1.
Shown in Fig. 1 composition graphs 3, elastic rib 1 is connected with draw gear 3, the effect of draw gear 3 is that realization makes elastic rib 1 spin off by lock groove 201 to the traction of elastic rib 1.In the present embodiment, draw gear 3 adopts drawstring, and in order to realize better being connected and fixed draw gear 3, and actv. reduces releasing force, elastic rib 1 is provided with and is pulled bending connecting portion 101 that direction bends, that be connected with draw gear 3 along elastic rib 1.
In order to be connected on cushion 200 by elastic rib 1, in the present embodiment, elastic rib 1 comprises horizontal segment 102 and vertical section 103, and wherein, horizontal segment 102 is as the effective section embedded in lock groove 201, and namely bending connecting portion 101 is arranged on this horizontal segment 102.Vertical section 103 is as the linkage section be connected with cushion 200, and its free end is fixedly connected on cushion 200.In addition, in order to strengthen the pretensioning effect of elastic rib 1, to guarantee the elastic strength of elastic rib 1, in the close of elastic rib 1 and cushion 200 junction, be provided with screw-shaped elastic reinforcement portion 104, shown in Fig. 3 composition graphs 4, elastic reinforcement portion 104 connection of the present embodiment is arranged between horizontal segment 102 and vertical section 103.As above the vibrational power flow of elastic rib 1, when draw gear 3 pairs of elastic rib 1 are pullled, elastic rib 1 is out of shape, in addition, in order to ensure the stability that elastic rib 1 is moved during elastic deformation pullling by external force, cushion 200 is fixed with the pivot shaft 4 interted in elastic reinforcement portion 104, due to the use of this pivot shaft 4, make elastic rib 1 when elastic deformation, can rotate for rotating fulcrum with pivot shaft 4, ensure that elastic rib 1 is relative to the location on cushion 200.
In order to during to elastic rib 1 elastic deformation, be subject to directional tagging, elastic rib 1 is caused to exceed its deformation limit to prevent draw gear from applying excessive tractive force, make unlocking operation person obtains unblock force-sensitive simultaneously, vehicle floor 100 is fixed with limit base 5, as shown in Figure 5, limit base 5 entirety becomes and to be connected the L-type formed by guide plate 501 and adapter plate 502, adapter plate 502 is provided with the through hole 503 passed through for bolt, limit base 5 is fixed on vehicle floor, guide plate 501 is provided with the long through-hole 504 inserted for elastic rib 1, the length of this long through-hole 504 is arranged along the trailed deformation direction of elastic rib 1, like this, elastic rib 1 is when stress deformation, the directional tagging of long through-hole 504 can be subject to, also be subject to the restriction of long through-hole 504 length direction simultaneously.In order to improve stability further, in the present embodiment, limit base 5 is for splitting two in snap close 2 both sides.
When needs unlock cushion, by pullling draw gear 3, make elastic rib 1 along the Direction distortion of tractive force, when elastic rib 1 is conflicted with the edge of long through-hole 504 length direction, operator experiences the limiting force of limit base 5, then prove that now horizontal segment 102 is deviate from by lock groove 201, its state as shown in Figure 6.Now, lift cushion 200, the unlocking operation of cushion can be realized.When by cushion 200 locking, because the external force of draw gear 3 disappears, elastic rib 1 returns to initial position, cushion 200 is from top to bottom being placed in locking process, the elastic rib 1 reverting to initial condition contacts with the inclined-plane 203 on prominent cap 202, due to the setting on this inclined-plane 203, elastic rib 1 can be placed cross the middle part of prominent cap 202 and slide into opposite side, now, firmly press down cushion, elastic rib 1 is out of shape under the directional tagging on inclined-plane 203, until after elastic rib 1 slides to the edge of prominent cap, embedded in lock groove 201 by the elastic restoring force of self.
As above structure is only the schematic description to the utility model wherein a kind of version, when reality uses, also can set up a stopper again on prominent cap 202, to prevent elastic rib 1 further more to the opposite side of snap close 2.
