The specific embodiment
Below with reference to accompanying drawing, provide the specific embodiment of the present invention, be used for that the present invention is described further.
A kind of tail-gate lock, comprises substrate 1, fore shaft support 2, tapping screw 3, fore shaft limited block 4, clamp torsion spring 5, lock pawl torsion spring 6, bearing pin 7, clamp 8, lock pawl 9, memory bar 10, lock pawl limited block 11, memory bar torsion spring 12, motor pad 13, microswitch 14, motor 15, transmission nut 16, motor gear 17, terminal 18, the gear 19 with screw rod, cover plate 20, back-moving spring 21, emergency opening arm 22, actuator bracket 23.
Wherein fore shaft limited block 4 and lock pawl limited block 11 are stuck on fore shaft support 2; Bearing pin 7 is riveted on clamp 8, memory bar 10 on substrate 1; One end of clamp torsion spring 5, memory bar torsion spring 12 is connected with clamp 8, memory bar 10 respectively; The other end of clamp torsion spring 5 contacts with substrate 1, and the other end of memory bar torsion spring 12 is connected with cover plate 20; Bearing pin 7 is riveted on lock pawl 9 on substrate 1; Lock pawl torsion spring 6 one end are connected with lock pawl 9, and the other end contacts with substrate 1; Groove on clamp 8 can mesh with the projection of lock pawl 9; The projection 25 that lock pawl is provided with can lock with the groove of remembering on bar 10; The projection 24 that clamp is provided with is removed above-mentioned locking under the effect of clamp torsion spring 5 with clamp 8.Cover plate 20 is fixing with substrate 1 riveted joint by two bearing pins 7; Emergency opening arm 22 is connected on cover plate 20.
Motor 15 is housed in actuator bracket 23, is contained in the pinion 17 on motor 15 axle branches, the gear 19 with screw rod that transmission nut 16, back-moving spring 21 are housed, microswitch 14 and terminal 18.Tapping screw 3 is fastening by actuator bracket 23 and substrate 1.Clamp 8 is controlled microswitch 14 by rotation, can trigger or cut-off signal.
Tail-gate lock is opened by lockup state, can open by electric control system or emergency opening arm 22.Now, if be pressed with weight or accumulated snow on automobile tail gate, clamp torsion spring 5 is not enough to automobile tail gate to upspring, and the projection 25 that lock pawl is provided with will lock with memory bar 10, and lock pawl 9 is no longer rebounded and clamp 8 engagements; Now, only need pull tailgate can open tailgate, snow load function realizes.
The course of work: during closing automobile tail-gate (as shown in Figure 2), tail-gate lock moves downward with tail-gate, and snap close forces clamp 8 to rotate in the counterclockwise direction; Now, memory bar 10 is not subject to stopping of projection 24 that clamp is provided with, and the other end is stopped the projection 25 that pawl is provided with and stops.After clamp 8 turns an angle, first engagement on lock pawl 9 and clamp 8, in half lockup state.Tail-gate lock continues descending, on lock pawl 9 and clamp 8 during second engagement, in full lockup state.Now, microswitch 14 is separated with clamp 8, triggers locking signal.
While opening tail-gate (as shown in Figure 2), can open by electric control system or emergency opening arm 22.During electric opening, electric control system is connected the electric current of motor 15, and motor 15 drives pinion 17 to rotate, and is driven with the gear 19 with screw rod of its engagement, and the transmission nut 16 on its screw rod moves and promotes lock pawl 9 along screw rod and departs from and clamp 8 engagements; Utilize emergency opening arm 22 to realize manually opened: while rotating counterclockwise emergency opening arm 22, emergency opening arm 22 lower ends promote lock pawl 9 and depart from and clamp 8 engagements.Now, if be not pressed with weight or accumulated snow on automobile tail gate, normally open, microswitch 14, by being subject to the effect of clamp 8, is converted to start signal; If be pressed with weight or accumulated snow on automobile tail gate, clamp torsion spring 5 is not enough to automobile tail gate to upspring, and the projection 25 that lock pawl is provided with will lock with the groove of remembering on bar 10, and lock pawl 9 can not rebounded and clamp 8 engagements.Now, microswitch 14, by being subject to the effect of clamp 8, is converted to start signal; Only need pull tailgate to open.
The above-mentioned course of work of the present invention is for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.Every still row in protection scope of the present invention of apparent variation that technical scheme of the present invention extends out or change that belong to.
