[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The intelligent lock of this utility model includes a housing and a lock beam 3. The housing is an elongated rectangular body with a notched circular hole at the top. The opening at the top of the notch forms a lock beam positioning blind groove 4. An arc-shaped track 5 is arranged inside the housing along the circular hole. One end of the arc-shaped track 5 extends through the housing to the bottom of the notch to form a lock beam outlet, and the other end is close to the lock beam positioning blind groove and is a closed end. Several V-shaped guide wheels 6 are spaced apart on both sides of the arc-shaped track 5. The lock beam 3 is composed of an arc-shaped slide rail 31 and an arc-shaped rack 32 set on the top of the arc-shaped slide rail 31. The lock beam 3 is set inside the arc-shaped track 5, and its arc-shaped slide rail 31 and V-shaped guide wheels 6 cooperate with each other to achieve sliding. A micro geared motor 7 is arranged inside the housing near the side of the arc-shaped track 5. The top output end of component 7 is equipped with a drive gear 8, which meshes with an arc-shaped rack 32 to drive the lock beam to rotate. Inside the housing, there is also a receiving cavity 9, which houses the main control board 10, battery pack 11, charging module 12, and fingerprint verification module 13. The main control board 10 is connected to the micro-gear motor 7 and the fingerprint verification module 13. A power module is integrated on the main control board. The battery pack 11 is connected to both the charging module 12 and the power module, providing power to all power-consuming modules. The fingerprint verification module 13 is mounted on the main control board 10 and extends from the front side of the housing. The charging module 12 is located at the bottom of the housing and has a USB interface. An opening on the side of the housing corresponds to the USB interface, allowing the battery pack to be charged via the USB interface. The USB interface allows for convenient and quick charging using a mobile phone data cable.

[0020] The lock's housing is a long, rounded rectangle, designed primarily for aesthetic purposes while accommodating the internal modules, making it visually appealing and suitable for use as a hanging ornament. A through hole 26 on the lower side of the housing facilitates the insertion of a cord, allowing it to be used as a hanging ornament in its normal function. The fingerprint verification module is used to register and recognize fingerprints. For initial unlocking with any fingerprint, press and hold for more than 8 seconds until the indicator light flashes green, then remove the finger and press briefly 5 more times. This completes the initial fingerprint registration, after which fingerprint unlocking can be used. The battery charging module ensures safe and efficient control of the battery charging process, extending battery life. The power module converts the battery power, ensuring the output voltage matches the operating power of each power module.

[0021] Here, the V-shaped guide wheel and the lock beam are structurally matched, forming a type of composite rack and pinion ring guide rail. The arc-shaped track, arc-shaped slide rail, and arc-shaped rack all belong to a 5 / 8 ring structure. The width of the arc-shaped rack is smaller than the width of the arc-shaped slide rail to avoid friction with the V-shaped guide wheel. The cooperation between the V-shaped guide wheel and the arc-shaped slide rail ensures relatively precise positioning of the arc-shaped rack on the lock beam, facilitating engagement with the drive gear and simplifying the drive process. The V-shaped guide wheel can be fixed or rotated via bearings; neither method affects the sliding of the arc-shaped track.

[0022] When in use, the fingerprint verification module on the outside of the housing is used to unlock. When the main control board receives the signal, it controls the micro geared motor to move. The drive gear rotates and drives the lock beam to rotate and extend into the lock beam positioning blind groove to lock, or to exit the lock beam positioning blind groove and return to the arc track to unlock. At this time, the main control board needs to record the first unlocking or locking status each time to facilitate the control of the micro geared motor to rotate forward or reverse.

[0023] To simplify program control, in this embodiment, a sensor for detecting the position of the lock beam is also provided. Before each lock is opened or closed, the position is determined by the sensor, and then the micro geared motor is controlled to rotate forward or backward. Specifically, a micro proximity sensor 14 is provided inside the housing located between the lock beam positioning blind groove 4 and the arc-shaped track 5. The transmitting end of the micro proximity sensor 14 corresponds to the end of the arc-shaped rack 32 of the lock beam 3.

[0024] In order to appropriately increase the rotational resistance of the lock beam and further increase the stability after locking, a driven gear 15 is arranged on the other side of the housing near the arc-shaped track 5 through a bearing seat. The driven gear 15 meshes with the arc-shaped rack 32 and the driven gear 15 rotates passively with the arc-shaped rack 32.

[0025] In addition, considering that users can call for help in case of danger, a push-button switch 16 and an alarm 17 are also provided inside the housing. The push-button switch 16 and the alarm 17 are respectively connected to the main control board 10. The push-button switch 16 extends from the rear side of the housing. If the push-button switch is pressed and held for more than 5 seconds, the main control board receives a signal and controls the alarm to sound a loud alarm, which can be a siren, a call for help, or other sounds.

[0026] To prevent accidental activation of the push switch, a recessed groove 18 is formed on the rear side of the housing corresponding to the push switch 16. The push switch 16 extends from the rear side of the housing and is located inside the recessed groove 18. An openable cover 27 is provided on the surface of the recessed groove 18. The bottom surface of the cover has protruding edges at both ends, which, when closed, makes the corresponding position of the push switch hollow, preventing accidental activation. One end is connected by a telescopic cable to prevent it from falling off, and the other end has a soft convex key on its inner side. A corresponding groove is formed in the recessed groove, and the soft convex key cooperates with the groove to facilitate the fixation of the cover.

[0027] In this embodiment, the housing includes a rear housing 1 and a front housing 2. The interior of the rear housing 1 is provided with a plurality of blind mounting holes 19 at intervals. The interior of the front housing 2 is provided with positioning posts 20 at positions corresponding to the blind mounting holes 19, and the positioning posts 20 are interference-fitted with the blind mounting holes 19. Furthermore, a plurality of blind mounting holes are also provided on the inner wall of the rear housing, located between the arc-shaped track 5 and the notched through hole, and the corresponding positioning posts are provided on the inner wall of the front housing to achieve sealing at the through hole of the housing.

[0028] Most of the internal structure is located on the rear housing 1, while the front housing 2 is an adapter structure, with a small portion of the structure formed by the cooperation of the rear housing 1 and the front housing 2. For example, the arc-shaped track 5 is formed by the cooperation of the rear housing 1 and the front housing 2. The arc-shaped slide rail 31 of the locking beam 3 is located within the arc-shaped track of the rear housing 1, and the arc-shaped rack 32 of the locking beam 3 is located within the arc-shaped track of the front housing 2. The V-shaped guide wheel 6 is located inside the corresponding through hole of the rear housing 1. The miniature geared motor 7 is located in the motor fixing area inside the rear housing 2 and can be fixed without falling out by the top positioning cover. The driving gear 8 is fixed to the top output end of the miniature geared motor 7, and the driven gear 15 is rotatably set inside the rear housing 1 through the bearing seat. The interior of the front housing 2 has clearance grooves at corresponding positions of the driving gear 8 and the driven gear 15. The charging module, battery pack, push-button switch, and alarm are all located inside the rear housing cavity, in the positioning slot, or fixed with bolts; the main control board is fixed to the top of the fixing post in the rear housing cavity by bolts, above the charging module, battery pack, push-button switch, and alarm; the fingerprint verification module is located on the top of the main control board and extends to the outside of the front housing.

[0029] Furthermore, to ensure the sealing of the front and rear housings, both the rear housing 1 and the front housing 2 have an outer edge 21. The edge of the rear housing 1 is a stepped edge that increases from the inside to the outside, and the edge of the front housing 2 is a stepped edge that increases from the outside to the inside to match it. Several first key groups 22 are provided at intervals on the inner side of the edge of the rear housing 1, and several second key groups 23 are provided on the inner side of the edge of the front housing. The second key groups 23 and the first key groups 22 cooperate with each other to lock and fix them in place.

[0030] To further secure the rear and front housings, the bottom surface of the locking beam positioning blind groove 4 is formed by the inner side plate 24 of the rear housing, and the inner side plate is provided with a threaded through hole. The front housing 2 is provided with a fixing plate 25 that fits against the bottom surface of the locking beam blind hole, and the fixing plate 25 is provided with a threaded blind hole. The bolt passes through the threaded through hole and is fixed in the threaded blind hole, thereby further locking the front and rear housings.
