Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-Figure 4, a kind of noise abatement automobile tail gate lock, comprise base 1 and the lock body 16 be arranged on base and actuator 13, described actuator 13 is connected by output shaft opens rocking arm 11, the side of opening rocking arm 11 arranges the emergent handle 12 that coaxially can turn, described lock body 16 is provided with intermeshing ratchet 2 and ratchet 9, described base 1 is connected with limit shaft 14 with emergent handle 12, described limit shaft 14 mainly plays when the position-limiting action to unlatching rocking arm 11 and emergent handle 12; Ratchet 2 is fixed on lock body 16 and base 1 by ratchet locating shaft 3, ratchet 9 is fixed on lock body 16 and base 1 by ratchet locating shaft 7, ratchet locating shaft 3 is provided with ratchet return spring 4, described ratchet locating shaft 7 is provided with ratchet return spring 8, on lock body, be provided with snap close buffer stopper 5 and guide pad 6 between ratchet 2 and ratchet 9, snap close buffer stopper 5 and guide pad 6 are made by elastomeric material; The setting of snap close buffer stopper 5 is to reduce the shock of snap close to ratchet 2 and lock body assembly; The shock place that the shock place of ratchet 2 and lock body 16 is provided with the first reset buffering block 17, ratchet 9 and lock body 16 is provided with the second reset buffering block 18, first reset buffering block 17 and the second reset buffering block 18 for elastomeric material and center all has U-shaped through hole; Ratchet 2 is respectively arranged with first buffer area 20, buffer area 19, second and the 3rd buffer area 21 of being made up of elastic rubber material, the noise that snap close produces the shock of ratchet 2 can be reduced, on described the ratchet 9 and shock place of ratchet 2 is provided with the 4th buffer area 22 of being made up of elastic rubber material, and unlatching rocking arm 11 and emergent handle 12 junction are provided with the first rubber sleeve 10; Emergent handle 12 and limit shaft place 14 are provided with the second rubber sleeve 15, avoid the collision of metal and metal, reach noise reduction effect.The hollow area that described first buffer area 20, buffer area 19, second, the 3rd buffer area 21 and the 4th buffer area 22 are set by encapsulate layer, plays cushioning effect.
The first reset buffering block 17 in the present invention and the second reset buffering block 18 center have U-shaped through hole, at ratchet 2 or ratchet 9 with the knockout process of lock body 16, reset buffering block can be divided into two parts in whole deformation process: the first, the elastic deformation of rubber bodies material itself; The second, the distortion of buffer stopper entirety, the distortion that namely extruded rubber bodies is shunk in U-shaped through hole under clashing into.The superposition of two portion deforms, considerably increases the deflection of reset buffering block, has slackened the energy clashed into and the vibration caused, and then has reached the object of noise abatement.
The operating principle of noise abatement automobile tail gate lock of the present invention is: enter lock process: snap close promotes ratchet 2 and advances in lock, lock body and guide pad 6 make snap close advance according to correct path, and compress snap close buffer stopper 5 and enter locked position of coupler, now ratchet 2 and ratchet 9 are engagement.
Releasing process: actuator 13 pulls opens rocking arm 11, unlatching rocking arm 11 drives ratchet 9 to rotate and is separated with ratchet 2, ratchet 2 gets back to initial position under the effect of ratchet return spring 4, compress the first reset buffering block 17, snap close exits lock body, reach unblock object, now ratchet 9 is got back to initial position and is compressed the second reset buffering block 18 under the effect of ratchet return spring 8; Releasing process can also directly use emergent handle 12, and emergent handle 12 drives coaxial unlatching rocking arm 11, and step is the same, completes releasing process.
