Description

Technical Field

[0001] This utility model relates to the field of smart door locks, and more particularly to low-power smart door locks. Background Technology

[0002] Low-power smart locks are devices that combine the security of traditional locks with the convenience of modern smart technology. These locks are typically battery-powered, so energy efficiency is a key design consideration to extend battery life and reduce the frequency of replacement or charging.

[0003] Utility model CN221220075U discloses a low-power smart lock, including a smart lock body. A handle with a fingerprint area is rotatably connected to the outside of the smart lock body. A fixing sleeve protecting the fingerprint area of ​​the handle is sleeved on the outside of the handle. A support rod that slides in a drive groove on the surface of the handle is welded to the inside of the fixing sleeve. A fixing block connecting a spring is welded to one side of the support rod. A storage slot for a battery is provided inside the smart lock body. This utility model solves the technical problem that existing low-power smart locks are inconvenient to protect the fingerprint area on the smart lock body during unlocking and also inconvenient to dissipate heat from the battery inside the smart lock body.

[0004] Although the low-power smart door lock with the above structure accelerates the airflow at the battery by installing a fan, it cannot centrally dissipate the heat dissipated by the battery, resulting in poor heat dissipation.

[0005] Therefore, it is necessary to provide a new low-power smart door lock to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a low-power smart door lock.

[0007] The low-power smart lock provided by this utility model includes a smart lock body, on which a fingerprint area and a password area are provided. A receiving slot is provided on the smart lock body, and a storage battery is installed in the receiving slot. A baffle is detachably connected to the smart lock body at the position corresponding to the receiving slot. Heat-conducting plates are installed on the two opposite inner walls of the receiving slot through elastic devices. When the storage battery is located between the two heat-conducting plates, the elastic devices are in a compressed state. Multiple heat dissipation fins are installed on the heat-conducting plates. Ventilation holes are provided on the two opposite side walls of the inner cavity of the receiving slot. Exhaust fans are fixedly installed in the through holes at both ends of the bottom wall of the receiving slot. The two exhaust fans are respectively set to correspond to the heat dissipation fins on the two heat-conducting plates.

[0008] Preferably, slide bars are fixed on both sides of the baffle, and slide grooves for placing slide bars are opened on both sides of the smart door lock body. A buckle device for limiting the baffle is installed in the placement groove opened at the bottom of the smart door lock body.

[0009] Preferably, the buckling device includes an abutment plate, a first spring, and a push plate. The abutment plate is movably inserted into a through hole in the inner wall of the placement groove. The two ends of the first spring are fixed to the abutment plate and the inner wall of the placement groove, respectively. The push plate is fixed on the abutment plate, and the bottom end of the push plate extends out of the outer side of the placement groove.

[0010] Preferably, the elastic device includes a rod, a second spring, and an adjusting assembly. The rod is movably inserted into a groove in the inner wall of the receiving groove. The adjusting assembly is mounted on the rod. The two ends of the second spring are respectively fixed to the adjusting assembly and the heat-conducting plate.

[0011] Preferably, the adjustment assembly includes a movable ring, a support plate, a guide rod, and a driving component. The movable ring is sleeved on the insert rod and is fixedly connected to the second spring. One end of the support plate is fixed to the movable ring. The guide rod movably passes through the support plate and one end of the guide rod is fixed to the inner wall of the receiving groove. The driving component is installed on the inner wall of the receiving groove.

[0012] Preferably, the driving component includes a threaded rod and a threaded sleeve. One end of the threaded rod is fixed to the inner wall of the receiving groove, and the threaded sleeve is threadedly connected to the threaded rod and rotatably connected to the support plate.

[0013] Compared with related technologies, the low-power smart door lock provided by this utility model has the following beneficial effects:

[0014] After the heat from the battery is conducted to the heat-conducting plate, it is then conducted to the heat dissipation fins. Since the two exhaust fans are set to correspond to the heat dissipation fins on the two heat-conducting plates respectively, the heat on multiple heat dissipation fins can be easily carried away by accelerating the airflow, thereby carrying out centralized heat dissipation and improving the heat dissipation effect.

[0015] By rotating the threaded sleeve, the support plate is limited by the guide rod, so the support plate drives the moving ring to move horizontally, thereby adjusting the elastic force of the second spring. This facilitates increasing the interaction force between the heat-conducting plate and the battery. When the elastic force of the second spring decreases, the deformation of the second spring can be increased in this way, thereby improving the interaction force between the heat-conducting plate and the battery.
