Description

Technical field of an intelligent door lock sliding cover

[0001] The present invention relates to the technical field of intelligent door locks, and more specifically, it relates to an intelligent door lock sliding cover.

Background technique

[0002] With the development of smart door locks, some smart door locks are exposed to the operation panel for a long time, the fingerprint recognition board and the password input board are prone to dust, dust will affect the accuracy of fingerprint recognition and the sensitivity of the password input board, causing the door The lock recognition function is weakened, affecting the service life of the door lock.

[0003] In order to protect the operation panel, a slide cover is usually provided on the lock body of the smart door lock, and the operation panel is covered by the slide cover to play a role of dust prevention. However, with the movement of the slide cover, the control panel will gradually accumulate dust after a period of use, and it is very inconvenient for the user to manually wipe it from time to time to clean it.

Summary of the invention

technical problem

[0004] In view of the above-mentioned technical problems, the object of the present invention is to: provide an intelligent door lock sliding cover that automatically cleans the operation panel during the sliding process.

Solution to the problem

Technical solution

[0005] In order to achieve the above object, the present invention proposes a new technical solution: an intelligent door lock sliding cover, which includes a sliding cover body that is fitted and slid on the lock body and can cover or expose the control panel by sliding, The two sides of the slide body are vertically integrated with a folding wall toward the control panel side, and there is a gap between the slide body and the control panel. Disassembly is provided with an adsorption cleaning mechanism that automatically cleans the control panel with the movement of the slide cover body. The adsorption cleaning mechanism mechanism includes a support shaft and support blocks on both sides of the support shaft. The support shaft is externally provided with a contact with the control panel An elastic adsorption layer, the supporting shaft is rotatably connected to the supporting block, and an end of the folding wall close to the sliding cover body covering the operation panel is symmetrically recessed with an accommodating groove for accommodating the supporting block, and a limited setting is provided in the accommodating groove A limit mechanism for moving the support block, when the slide body moves back and forth to the maximum stroke , The suction cleaning mechanism leaves the control panel.

[0006] According to the above technical solution: Compared with the existing sliding cover, the sliding cover in this solution is additionally provided with an adsorption cleaning mechanism mechanism, and the adsorption cleaning mechanism does not need to provide a power mechanism, while the operator slides the sliding cover body The adsorption cleaning mechanism moves synchronously with the movement of the slider body to adsorb the dust on the surface of the control panel. When the slider moves to the maximum stroke, the adsorption cleaning mechanism will not touch the control panel, which will not affect the control panel. Normal use; when used for a period of time, the adsorption cleaning mechanism can be removed for replacement or cleaning, which is very convenient. The smart door lock sliding cover can ensure that the touch screen is in a dust-free state in real time, improving the recognition of the touch screen Accuracy and sensitivity, thereby extending the service life of only door locks.

[0007] The present invention is further configured as follows: the shape of the support block is T-shaped, the end of the small area of the support block faces the inner wall of the folded wall and is flush with the inner wall of the folded wall, the support shaft is rotatably connected to the end of the small area of the support block .

[0013] The present invention is further configured as follows: the bottom of the accommodating groove is provided with a thrust mechanism for pushing the support block out of the accommodating groove, the thrust mechanism is a second return spring, when the limit block is inserted into the slot hole , The second return spring is in a contracted state.

[0014] According to the above technical solution: the setting of the thrust mechanism plays a pushing role on the support block, which is convenient for the support block to be taken out from the accommodating groove. When the support block is limited by the limit block, the second return spring is contracted Status; After the limit block retracts, the second return spring resets the support block out of the accommodating groove, thereby facilitating the removal of the cleaning reset mechanism.

[0015] The present invention is further configured as follows: the elastic adsorption layer is made of water-washing glue, the elastic adsorption layer is glued to the support shaft by glue.
