Specific embodiment
In order to be more clear goal of the invention of the invention, technical solution and its advantageous effects, below in conjunction with attached drawing
And specific embodiment, the present invention will be described in further detail；
In the accompanying drawings: automobile left front door latch, including left housing lid 3, left shell 9；It is characterized by: on the left housing lid 3
It is provided with the through-hole of installation latch lockup arm 1, is provided with sealing ring 10 in through-hole；Left housing lid 3 is internally provided with latch letter
Number rocker arm 11 is provided with buffer stopper 2 in the inner hole of latch signal rocker arm 11；The latch lock of the top of left housing lid 3 is set
Only it is matched fixation with latch signal rocker arm 11 by the through-hole on left housing lid 3 by arm 1；It is set inside the left shell 9
It is equipped with motor 15, left copper pin a7 and left copper pin b16 are provided on motor 15, worm screw 6 and 4 phase of helical gear of motor 15 are nibbled
It closes；Return spring a5, return spring b18 are provided on the axis 19 of the helical gear 4, axle sleeve 13 is separately positioned on a left side of return spring a5
The right end at end and return spring b18, and push rod 12 is provided between return spring a5 and return spring b18, push rod 12 and axis 19 are mutual
Vertically；Microswitch 14 is additionally provided with inside the left shell 9；Sealing ring 8 is provided between left shell 9 and left housing lid 3.
It is locked between the left shell 9 and left housing lid 3 by recessed pan head tapping screw 17；The microswitch
