Specific embodiment
In order to be more clear the goal of the invention, technical solution and its advantageous effects of the utility model, below in conjunction with
The drawings and specific embodiments, the present invention will be further described in detail；
In the accompanying drawings: a kind of electronic child lock, including lower cover plate sub-unit 1 and upper cover plate sub-unit 2；The lower cover plate point
Motor worm combination 3 is provided in assembly 1；The motor worm combination 3 has been engaged turbine 4；The turbine 4 passes through transmission
Bar 5 is sequentially connected with lock body mechanism 6；Such as Fig. 1, lock body mechanism include: in open rocker arm shaft 61, it is interior open interlock plate 62, coupling spindle 63,
Inside open rocker arm 64, sliding shoe 65；Sliding boss 11 are provided in the lower cover plate sub-unit 1；At the center location of the turbine 4
It is provided with positioning convex platform 41, transmission boss 42 is provided at the circumferential edges position of turbine 4；It is horizontal on the right part of the drive rod 5
To positioning through hole 51 is provided with, transmission through-hole 52 is vertically provided on the right part of drive rod 5；The positioning convex platform 41 and positioning are logical
Hole 51 matches；The transmission boss 42 matches with transmission through-hole 52；The middle part of the drive rod 5 is sliding by sliding through hole 53
It is dynamic to be arranged in sliding boss 11；The lower section of the sliding boss 11 is provided with positive stop lug boss 12 in lower cover plate sub-unit 1；
The upper end of the drive rod 5 is provided with signal output switch 7 in lower cover plate sub-unit 1；It is logical using sliding among drive rod 5
Hole 53 is slidably arranged in the sliding boss 11 in lower cover plate sub-unit 1, and the right end of drive rod 5 passes through the matching peace of positioning through hole 51
On positioning convex platform 41, it is arranged on transmission boss 42 by the transmission matching of through-hole 52, turbine 4 is in motor worm combination 3
Lower rotation is driven to realize the folding and locking of lock body mechanism 6 to steadily drive rod 5 or so be driven to translate；Due to turbine 4
Pass through the positioning method of two groups of through-holes and boss between drive rod 5, thus it is not easily to fall off in later period transmission process, guarantee child lock
Normal work；Only needing to be arranged corresponding through-hole on drive rod 5 can be realized gearing operation, reduce the production cost of enterprise.
The turbine 4 is set as semicircular structure；Can be seen that the smaller of 4 volume of turbine in conjunction with Fig. 1 and Fig. 2 can subtract
The occupied space of small children lock, realizes tinyization and more optimized purpose.
The upper end of the drive rod 5 is provided with inductive slot 54 at 7 position of signal output switch；The inductive slot 54 with
Signal output switch 7 matches；In conjunction with Fig. 2 and Fig. 3, the matching of signal output switch 7 is arranged in inductive slot 54, can be fed back to
Whether driver's child lock opens or closes, and realizes electronic purpose.
The positioning through hole 51 is set as waist-shaped hole, and the lower wall surface of the hole of positioning through hole 51 is set as arc surface；In conjunction with Fig. 2 and
Fig. 3, the lower arm of positioning through hole 51 are set as arc surface structure, when can reduce the rotation of turbine 4, positioning convex platform 41 and positioning through hole
Stuck phenomenon is caused between 51.
The specific implementation of the utility model: when driver by press it is main drive a child lock button when, motor worm combination 3
It being powered and worm gear 4 is driven to rotate, worm gear 4 drives drive rod 5 or so to translate, and at this moment sliding shoe 65 and coupling spindle 63 move left and right,
When coupling spindle 63 be moved in open in 64 left side waist hole of rocker arm, by it is interior open rocker arm 64 be just unable to drive in open interlock plate 62 open
Car door, drive rod 5 touches signal output switch 7 and outputs signal to BCM and on instrument desk or signal after prompting driver at this time
Door functions of child lock has been opened.
