Detailed description of the invention
A kind of automobile door lock utilizes the safety protection mechanism that inertia triggers, including outer release lever 1, locking connecting rod 2 and card
ZHUANLIAN bar 3.Described outer release lever 1 can rotate around the first rotary shaft 10 under active force outside, and described locking connecting rod 2 is by second
Rotary shaft 20 is installed on outer release lever 1, and described claw connecting rod 3 can rotate around the 3rd under the impetus of locking connecting rod 2
Axle 30 rotates.The present invention is additionally provided with inertia disk 4 and coupling spring 5, and described inertia disk 4 can rotate around the 4th rotary shaft 40, institute
Stating inertia disk 4 to be provided with and the connection post 41 of the 4th rotary shaft 40 bias, described locking connecting rod 2 is provided with chute 21, described company
Connecing post 41 locking to be limited in chute 21, described coupling spring 5 is installed on locking connecting rod 2 and is biased on outer release lever 1.
The safety protection mechanism that automobile door lock of the present invention utilizes inertia to trigger includes lock body 6, and described inertia disk 4 is by above-mentioned
4th rotary shaft 40 is installed on lock body 6.
Described locking connecting rod 2 is provided with block 22, and described lock body 6 is provided with the inclined-plane abutting with block 22 and can separating
61.Block 22 abuts with inclined-plane 61, it is possible to ensure under original state (i.e. not applying the situation of outer active force release lever 1 outside),
Described connection post 41 is only limited in chute 21, and there is not the effect of power between locking connecting rod 2 and inertia disk 4；Outside once
Active force promotes outer release lever 1, after block 22 separates with inclined-plane 61, i.e. produces the work of power between locking connecting rod 2 and inertia disk 4
With.
Described locking connecting rod 2 includes the free end 23 near claw connecting rod 3 away from outer release lever 1, described second rotation
Rotating shaft 20 is located at the other end on locking connecting rod 2 relative to free end 23.Second rotary shaft 20 must be arranged on locking connecting rod 2
Relative to the other end of free end 23, could rotate up during moving right.
Described locking connecting rod 2 includes the arm 24 between the second rotary shaft 20 and free end 23, described coupling bomb
Spring 5 include the cast portion 50 in the second rotary shaft 20 that is set in and the first leg 51 extended on the contrary from the two ends in cast portion 50,
Second leg 52, described first leg 51 is resisted against on arm 24, and the second leg 52 is resisted against on outer release lever 1.Coupling spring 5
Main body has the second leg 52 being resisted against on outer release lever 1 while being arranged on locking connecting rod 2, thus locking connecting rod 2 can
To rotate relative to outer release lever 1 while linking with outer release lever 1.
Described chute 21 is on arm 24 and between the second rotary shaft 20 and free end 23.
Described free end 23 can contact with claw connecting rod 3, and when free end 23 contacts with claw connecting rod 3, locking is even
Bar 2 push card ZHUANLIAN bar 3 normal release.
Described free end 23 can not contact with claw connecting rod 3 and below claw connecting rod 3 slip, free end 23 from
When slipping below claw connecting rod 3, claw connecting rod 3 keeps lockup state.
Above, if push card ZHUANLIAN bar 3 normal release, depend on acting on the speed of operation on outer release lever 1 or
The size of acceleration.
The present invention is when automobile is subjected to bigger impulsive force (being equivalent to quickly pull outer release lever), due to inertia disk 4
Effect, it is impossible to by automobile door lock unlock, it is therefore prevented that being opened accidentally of car door, protection driver and crew safety.
Described inertia disk 4 and coupling spring 5 are positioned at inside and outside locking connecting rod 2.
Described locking connecting rod 2 and the rotation synchronization of inertia disk 4 but trend is contrary.Time at a slow speed, locking connecting rod 2 is the most counterclockwise
Rotating, inertia disk 4 is along rotating clockwise；Time quickly, locking connecting rod 2 slides the most to the right and is not rotated up, and inertia disk 4 does not turns
Dynamic.
Concrete operation principle is: locking connecting rod 2, under the effect of coupling spring 5, exists becoming of rotating up counterclockwise
Gesture (direction that in Fig. 1, arrow represents), it is possible to drive inertia disk 4 to rotate.During lock body release, outer release lever 1 rotates counterclockwise, when
When acting on the speed of operation on outer release lever 1 or acceleration less than certain certain value, locking connecting rod 2 is moving right process
In, rotate counterclockwise simultaneously, because speed is slow, the when that the locking of described connection post 41 being limited in chute 21, locking is even
There is an active force and counteracting force between bar 2 and inertia disk 4, when locking connecting rod 2 rotates, drive inertia disk 4 around the 4th rotation
Axle 40 rotates, and the free end 23 of locking connecting rod 2 touches and push card ZHUANLIAN bar 3, it is achieved normal release；When acting on outer releasing
When putting the speed of operation on bar 1 or acceleration higher than certain certain value, locking connecting rod 2 is during moving right, due to speed
Than very fast, so in the case of inertia disk 4 also has little time to rotate, the connection post 41 of inertia disk 4 is the most in the cunning of locking connecting rod 2
Sliding in groove 21, the free end 23 of locking connecting rod 2 can slip from the lower section of claw connecting rod 3, thus cannot unlock, it is achieved protection
Effect.
