The present application claims priority of Chinese Patent Application No. 202221555080.3, filed on Jun. 28, 2022, the entire contents of which are hereby incorporated by reference.
The present disclosure relates to an electronic handle door lock easy to install and use, belonging to the technical field of locks.
A door lock is a device used to lock a door to prevent others from opening the door. Many kinds of door locks come into being, and have different requirements in different occasions. With the development of technology, the door locks are becoming more varied, including locks unlocked manually by keys and electronic locks unlocked by electronic signals. With the improvement of the quality of life, the simple fashionable electronic door locks are popularized among more and more people, such that simple electronic handle door locks have become the new favorite of the market. Such simple electronic handle door locks are characterized by small structural spaces. In limited spaces of handles of the simple electronic handle door locks, an electronic unlocking method and a manual key unlocking method are designed, and a power supply method is arranged reasonably. For example, a smart fingerprint lock handle disclosed in Chinese Utility Model application number 201921361392.9 filed by the applicant is mainly locked or unlocked by connecting a front handle with a rear handle through an electromagnetic clutch apparatus, and can be unlocked by the front handle by only giving a fingerprint unlocking signal. However, the electromagnetic clutch apparatus has high requirements on the magnetic strength of the magnet, and occupies a large structural space. A power supply component can be mainly arranged on the rear handle, and a power supply connecting line can be guided to the front handle through a middle portion of an linkage square tube so as to be connected with a control circuit board. In this way, the linkage square tube rotates in a long time, which will easily cause the wear to the power supply connecting line, and brings the inconvenience for the installation. An incorrect installation method may easily cause the head of the power line to fall off. For another example, a novel smart lock disclosed in Chinese Utility Model application number 202022887005.4 filed by the applicant solves the previous handle power supply method and reduces the power supply connecting line, manual unlocking by a key can not performed due to a large space occupied by a clutch structure. Accordingly, the novel smart lock is limited in applications. Moreover, the battery case has an unreasonable structure, which brings the inconvenience for replacing the battery.

With reference to
A working principle of the present disclosure will be described as follows. The battery case 5 of the present disclosure can be directly inserted into the battery case installing slot 21 from one side of the front handle 2 and locked and fixed by a screw. The battery is installed within the battery case 5. The battery is inserted within the battery case installing slot after being placed into the battery case 5. The battery is pushed to the electrically conductive plate 41 under an elastic action of the spring 51. The electrically conductive plate 41 is directly connected with the control circuit plate 41 via a power supply connecting line by respectively connecting a positive polarity contact and a negative polarity contact of the battery with the electrically conductive plate 41 without pulling the power supply connecting line to the rear handle 1. In this way, the wear of the power supply connecting line can be reduced, the service life of the power supply connecting line is prolonged, and the power supply connecting line is conveniently used and replaced. The control circuit board 4 directly controls the driving motor 61 to rotate via a wire. The driving motor 61 drives the rotating shaft 62 to rotate. When the pins 621 on two sides of the rotating shaft rotate, the pins 621 on two ends can rotate along a helical gap of the engaging spring 64, and the engaging spring 64 can deform forwards or backwards, thereby producing a pushing force for pushing the pushing member 63 and the latching pin 67 arranged on one side of the pushing member 63 forwards. The latching pins 67 are directly engaged in the latching pin limiting slot 81 of the clutch rotating rod 8 after being pushed forwards, such that the electronic handle door lock is unlocked by rotating the front handle 2. The electronic handle door lock is convenient and reliable to use. Meanwhile, since the return springs 68 are mounted around the latching pins 67, the pushing member can return under an elastic action of the return springs 68 during retreating.
It should be noted that a head end and a tail end of the engaging spring 64 of the present disclosure extend outwards, such that extending portions of an upper end and a lower end of the engaging spring 64 can be engaged within the limiting slot 632. Moreover, the manual clutch lock cylinder provided is mainly used for backup unlocking. Technical features are relatively common compared with the prior art, and will be omitted in the specification.
The present disclosure is an electronic handle door lock easy to install and use, which is mainly improved over the above structure. Unmentioned functions, components and structures may be implemented by using components and structures capable of realizing corresponding functions in the prior art.
