Specific embodiment
A kind of new type of safe protection mechanism of automobile door lock, including outer release link 1, unlocking link 2 and latch ratchet
3.Connected by rotary shaft 4 between the outer release link 1 and unlocking link 2, the outer release link 1 is provided with arc-shaped through-hole 11
And form the arc inward flange 12 at the edge of arc-shaped through-hole 11.The new type of safe protection mechanism of the utility model automobile door lock also sets
There are inertia bull stick 5, torsion spring 6 and oblique boss 7.The inertia bull stick 5 have be limited in small boss 51 in arc-shaped through-hole 11 and
From the push rod 52 that the one of small boss 51 extends, the small boss 51 is positioned and can slid against in above-mentioned arc with torsion spring 6
Flange 12.The unlocking link 2 has the first extension 21 for protruding out towards inertia bull stick 5 and crossing push rod 52 and towards locking
Ratchet 3 protrudes out and can be with the second extension 22 of the movable contact of latch ratchet 3.The push rod 52 is configured at the first extension 21
A side and the free end of push rod 52 can be abutted with the lateral margin of the first extension 21.The torsion spring 6 is configured at oblique boss 7
Side and can activity positioned at oblique boss 7 opposite side.
The inertia bull stick 5 and unlocking link 2 are configured at the back side of outer release link 1, and the torsion spring 6 is configured at outer release
The front of connecting rod 1, the small boss 51 passes through arc-shaped through-hole 11 and the convex front for being exposed to outer release link 1.
The outer release link 1 is provided with locating dowel 13, and small boss 51 is provided with the through hole (not shown) for penetrating up and down.It is described
Oblique boss 7 includes the slope 71 in left side and the cliff 72 positioned at the right side of slope 71, and the torsion spring 6 is including cast portion 61 and certainly
The first leg 62, the second leg 63 that the two ends of cast portion 61 conversely extend, the first leg 62 are resisted against in locating dowel 13, the second leg
Portion 63 through small boss 51 through hole and can with the cliff 72 of oblique boss 7 against.
Between the extension 21 of the push rod 52 and first and the torsion spring 6 the second leg 63 and oblique boss 7 between
Asynchronously contact.That is, under normal release state, the first extension of pushing tow 21 of the push rod 52, and the second leg of the torsion spring 6
Do not contacted between 63 and oblique boss 7；Under guard mode, the second leg 63 of the torsion spring 6 is positioned in oblique boss 7, and institute
State and do not contacted between push rod 52 and the first extension 21.
The rotary shaft 4 is positioned on lock body (not shown), and the oblique boss 7 is formed on lock body.That is, described rotation
Axle 4 and oblique boss 7 are arranged on the lock body beyond outer release link 1, unlocking link 2 and latch ratchet 3.
The inertia bull stick 5 is provided with balancing weight 53, and the balancing weight 53 is contained in arc-shaped through-hole 11.The mesh of balancing weight 53
Be the rotation sensitive for changing inertia bull stick 5 of the automobile in collision process, the quality of balancing weight 53 and position are mainly tune
The size and Orientation of whole inertia force.
In collision process, the velocity of rotation of outer release link 1 can be while the size of induction acceleration and speed.When outer
When the velocity of rotation or acceleration of release link 1 are less than certain certain value, the downward pushing tow small boss of lowermost end of arc inward flange 12
51, drive the push rod 52 to be abutted with the first extension 21, so that promote unlocking link 2 to be rotated clockwise around rotary shaft 4, second
Extension 22 is abutted with latch ratchet 3 so as to promote latch ratchet 3, realizes normal release function；When outer release link 1 rotates speed
When degree or acceleration are higher than certain certain value, inertia bull stick 5 overcomes the resistance of torsion spring 6 in the presence of inertia force, turns counterclockwise
Dynamic, small boss 51 can not be described by the downward pushing tow of arc inward flange 12 from lowermost end upward sliding along arc inward flange 12
Push rod 52 is also rotated counterclockwise with inertia bull stick 5, small boss 51 drive torsion spring 6 one end deflect to oblique boss 7 against,
Push rod 52 can not be abutted with the first extension 21, so as to unlocking link 2 can not be promoted to be rotated clockwise around rotary shaft 4, unblock connects
The remains stationary state of bar 2, i.e. the second extension 22 can not promote latch ratchet 3 to unlock, and realize protective effect.
