Description
Technical field
The utility model is related to a kind of electronic lock construction, more particularly to a kind of electronic lock construction with protection device.
Background technology
With the continuous progress of intelligent lock technology, the precision of each part is improved constantly on its panel, these corresponding portions
The maintenance cost of part is also improved constantly, and to keep the service precision and service life of each part, one can be set on panel
Moveable pushing cover is protected to each part.
In the prior art, there are the two class door locks with manual pushing cover and automatic pushing cover, wherein electric lock structure operation
It is convenient, operator can be brought more excellent usage experience.At present, general electronic lock construction is made up of pushing cover and panel,
The pushing cover madial wall is provided with rack, and the panel itself correspondence position is provided with motor, agreed with rack
Gear.Rotated by motor-driven gear, drive pushing cover to slide up and down, so as to realize the function of automatic pushing cover.
Patent No. CN201220389652.5 utility model patent disclose it is a kind of with slip lid and housing from
Dynamic slip lid door lock, wherein correspondence position in the guide rail slided in the slip lid provided with rack and guiding slip lid, the housing upper end
Provided with motor and with being installed on the gear on motor and for driving rack and the track groove of corresponding slip lid guide rail slip, institute
State slip lid inwall centre position and be provided with rack vertically, be respectively equipped with a guide rail on two madial walls of the slip lid.
But during real use, it is impossible to avoid operator from moving the feelings of pushing cover manually by force in use
Condition, there is also causing motor not work, it is necessary to the situation of manually opened slip lid due to battery electricity shortage, when pushing cover is by non-
When electronic external force (such as artificial slip manually) effect is slided by force, there is following harmful effect：
If the 1, pushing cover motion drives pinion rotation, so that motor is rotated, motor produces electric current, influence connection after rotating
The circuit of motor and each parts precision.
If the 2, pushing cover motion and motor remains stationary, will make be arranged on motor on gear burst apart, pushing cover can it is stuck and
It can not slide.
In addition, when motor rotation driven gear is moved, can not exclude and there may be the feelings that gear is blocked by extraneous factor
When condition, such as pushing cover move to panel lowermost end, gear may external force effect it is static suddenly, the motor being now rotated further can be by
To abrasion, gear be able to may also burst apart, and cause pushing cover is stuck can not normally use.
