Abstract

The utility model provides a flexible sliding cover device. The flexible sliding cover device comprises a lock case, and a slowdown motor assembly and a gear device both arranged in the lock case; an output shaft is a semi-cylinder; a flange (23) is formed on the output shaft; the gear device sleeves the output shaft; a hole (22) is formed in a transmission gear, and a ball and a compression spring are arranged in the hole (22) and fixed by a baffle plate; a rack (21) is arranged on the sliding cover; a reduction gear is arranged between the rack (21) and the transmission gear (51), and the rack (21) is engaged with the reduction gear and the reduction gear is engaged with the transmission gear; when the sliding cover is driven by the motor to move up and down, the sliding cover can be completely closed or opened by virtue of mechanism compensation; the motor and a reduction compound gear (42) are avoided from shock or impact force, and therefore, the reduction compound gear is protected against breakage or the motor is protected against damage, and finally, the problem that the sliding cover is locked or incapable of moving is solved at last; an automatic sliding cover lock driven by the existing motor is realized, the service life of the reduction compound gear and the motor is effectively protected, and the purpose of completely closing and opening the sliding cover is also achieved.

Description

A kind of flexible cover sliding device

Technical field

The utility model lock body relates to a kind of application of lockset industry, especially fingerprint door lock and electronic lock.

Background technology

At present, on market, in existing slip lid door lock, slip lid is gear drive entirely, under motor operation, use the pass of slip lid to enter and open to occur incomplete phenomena, that is to say slip lid can not open completely or close completely into, in addition owing to being single machine driving between slip lid rack and pinion, can not overcome very stiff and demanding phenomenon, and occur the phenomenon of gear breaking, thereby reduce the application life of product; The present utility model a kind of flexible cover sliding device, the application life of prolonged deceleration motor and slip lid, ensure product use more reliable, safer.

Utility model content

The utility model object is to realize a kind of flexible cover sliding device on door lock, when driven by motor slip lid moves up and down, can slip lid completely be entered or be opened in pass by mechanical compensation, motor and the combination tooth 42 that slows down can not be impacted or impact, cause slowing down combination tooth fracture or motor damages, and finally solves the problem of the stuck or akinesia of slip lid; Realized existing motor-driven automatic sliding cover door lock, effectively protection is slowed down the life-span of combination tooth and motor, also reaches the object that slip lid can close completely into and open.

It is as described below that the invention solves the technical scheme that its technical problem adopts: a kind of flexible cover sliding device, comprises lock housing 1, and in lock housing, be provided with fingerprint window 3, slip lid 2, reducing motor assembly 4, geared system 5, reduction gearing 6; Described reducing motor assembly 4 is made up of motor 41, the combination tooth 42 that slows down, output shaft 43, described geared system 5 is made up of travelling gear 51, ball 52, stage clip 53, baffle plate 54, it is characterized in that, output shaft is semicylinder, on output shaft, have rib 23 and rib 24, geared system is enclosed within on output shaft, on travelling gear porose 22, wherein ball, stage clip are placed in hole 22, are fixed by baffle plate.

On described slip lid 2, have tooth bar 21, tooth bar 21 is intermeshing with reduction gearing 6, and reduction gearing and travelling gear 51 are intermeshing, and wherein reduction gearing is placed between tooth bar (21) and travelling gear 51.

According to said structure, technology of the present utility model is to realize the existing slip lid door lock of flexible cover sliding device, when driven by motor slip lid moves up and down, can slip lid completely be entered or be opened in pass by mechanical compensation, motor and the combination tooth 42 that slows down can not be subject to huge impact or impact, cause slowing down combination tooth fracture or motor damages, and finally solves the problem of the stuck or akinesia of slip lid, so the utility model solves this technical barrier.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

The front view of the flexible cover sliding device of Fig. 1, has specifically shown each component mounting position.

The A-A sectional drawing of the flexible cover sliding device of Fig. 2 Fig. 3, when slip lid place open mode, porose 22 on travelling gear, Qi Zhongqiu, stage clip are put in hole 22, are fixed by baffle plate.

The exploded perspective view of the flexible cover sliding device of Fig. 4, has rib 23 and rib 24 on described output shaft 43.

The E-E sectional drawing of the flexible cover sliding device of Fig. 5, described reducing motor assembly 4 is made up of motor 41, the combination tooth 42 that slows down, output shaft 43; In the time that the power of slip lid 2 is exported in motor 41 rotations, combine tooth 42, output shaft 43 by deceleration, on output shaft, there is rib 23 that power is passed to ball, make freely upper and lower motion of slip lid through travelling gear, reduction gearing 6.

In the time that electric machine rotation drives slip lid to move up, can by driven by motor slip lid close into, when slip lid puts in place and spacing by rib 25, motor can rotate several circles more slip lid is closed completely, at this moment the output shaft in geared system 5 just rotates around ball, be that ball and output shaft are thrown off rotation, ball and output shaft play centrifugation, thereby motor, the combination tooth that slows down dally; This hour rack 21 can be not stressed; the combination tooth that slows down so can not be subject to huge impact force or impact; combine thereby having avoided slows down the phenomenon that tooth 42 skids or bursts apart, guarantee that slip lid and motor are always in normal operation, thereby stop the phenomenon generation that stuck or akinesia appear in slip lid.

The flexible cover sliding device C-C of Fig. 7 Fig. 8 sectional drawing, in the time that electric machine rotation drives slip lid 2, slip lid place closure state; In the time that motor rotates backward drive slip lid 2, slip lid place open mode, as Fig. 2, Fig. 3.
