A kind of automobile door lock opens release structuresTechnical field
The present invention relates to automobile door lock technical field is and in particular to a kind of automobile door lock opens release structures.
Background technology
Automobile door lock develops into today, and the mechanism of itself and function are all ripe, and people are also gradually changing viewpoint, fullWhile sufficient functional requirement, the requirement to operation comfort also becomes more and more higher, in order to meet the needs of client and market, IBe accomplished by product is constantly improved.
For automobile itself, car door open during because door weather strip is in pressurized state, by doorLock lock applies the power of opening direction to door lock ratchet.During opening car door, ratchet discharges ratchet, can produce in the moment opened" bang " a sound plosive.Client increasingly can not accept the noise producing when opening the door, and ratchet is produced during abrupt release makes an uproarThe problem of sound is in the urgent need to address.
Content of the invention
It is an object of the invention to provide a kind of car door that can produce noise problem effectively solving opening vehicle door momentRelease structures opened by lock.
The purpose of the present invention is achieved through the following technical solutions:
A kind of automobile door lock opens release structures, and described unlatching release structures include pedestal, slow release arm, ratchet, ratchet, instituteState slow release upper-arm circumference to rotate around the slow release arm axle that is arranged on pedestal, slow release arm is provided with so that slow release arm rotate after returnSlow release arm torsion spring；Described ratchet rotates around the ratchet shaft being arranged on pedestal, ratchet is provided with so that ratchet turnsThe ratchet torsion spring of return after dynamic；Described ratchet rotates around the pawl axis that are arranged on pedestal, ratchet is provided with so thatThe ratchet torsion spring of return after pawl rotation, described slow release arm is designed with slow release cambered surface, confined planes, dress spring face.
Further, on described slow release arm, the slow release cambered surface of setting is mutually linked with ratchet.
By technique scheme so that frictional force is little when ratchet promotes slow release arm during unlatching and locking, moveSmooth.
Further, on described slow release arm, the confined planes of setting and pedestal interact.
By technique scheme, effectively slow release arm can be limited in initial position.
Further, on described slow release arm, the dress spring face of setting is interacted with slow release arm torsion spring it is ensured that slow release arm energy canThat leans on is returned to initial position.
The beneficial effects of the present invention is:
Present configuration is simple, easy and simple to handle, safe and reliable, effectively solving opening vehicle door moment can produce noiseProblem.

Specific embodiment
Referring to Fig. 1～5, the specific embodiment of the invention employs the following technical solutions: a kind of automobile door lock opens slow release knotStructure, including pedestal 1, slow release arm 4, ratchet 5, ratchet 9, slow release arm 4 rotates around the slow release arm axle 3 being arranged on pedestal 1, slow releaseThe slow release arm torsion spring 2 of return after being provided with arm 4 slow release arm 4 is rotated；Ratchet 5 is around the spine being arranged on pedestal 1Wheel shaft 7 rotates, the ratchet torsion spring 6 of return after ratchet 5 being provided with ratchet 5 is rotated；Ratchet 9 is around being arranged on pedestalPawl axis 8 on 1 rotate, and after ratchet 9 being provided with ratchet 9 is rotated, the ratchet torsion spring 10 of return, slow release arm 4 setsIn respect of slow release cambered surface 11, confined planes 12, dress spring face 13.Wherein, on slow release arm 4, the slow release cambered surface 11 of setting is mutually interconnected with ratchet 5Move so that frictional force is little when ratchet 5 promotes slow release arm 4 during unlatching and locking, motion smoothing is smooth；Set on slow release arm 4The confined planes 12 put and pedestal 1 interact, and effectively slow release arm 4 can be limited in initial position；The dress spring of setting on slow release arm 4Face 13 and slow release arm torsion spring 2 interact it is ensured that slow release arm 4 can reliably be returned to initial position.
According to above-mentioned construction, when automobile door lock is in full lock position (as shown in Figure 1), in opening process, ratchet 9 stress aroundPawl axis 8 rotate, and discharge ratchet 5, and ratchet 5 around ratchet shaft 7 rotate counterclockwise, rotates in the presence of ratchet torsion spring 6 returning place forceDuring promote slow release arm 4 to turn clockwise around slow release arm axle 3 simultaneously, slow release arm 4 rotates clockwise to be needed to overcome slow release armThe active force (as shown in Figure 2) of torsion spring 2.Because in opening process, slow release arm 4 is applied with an obstruction ratchet 5 and releases to ratchet 5The active force put, reduces the release force of ratchet 5, reduces the rate of release of ratchet 5, thus reduce ratchet 5 release moment producingRaw noise.When ratchet 5 reaches opening, slow release arm 4 and ratchet 9 are respectively in slow release arm torsion spring 2 and ratchet torsion spring 10 returnIt is returned to initial position (as shown in Figure 4) in the presence of power.
During locking, ratchet 5 stress turns clockwise (as shown in Figure 5), promotes ratchet 9 and slow release arm 4 to revolve counterclockwiseTurn, ratchet 5 smoothly reaches locking states (as shown in Figure 1).
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned enforcementExample, all technical schemes belonging under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the artThose of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modificationsShould be regarded as protection scope of the present invention.
