Description

Technical Field

[0001] This utility model relates to the field of fingerprint locks, specifically to a fingerprint lock for glass doors. Background Technology

[0002] Cabinet locks, as crucial components for property security, have a wide range of applications, including but not limited to homes, businesses, and industries. Furthermore, cabinet locks can be integrated with smart systems to achieve functions such as door control and access recording. They not only possess the security features of traditional locks but also incorporate intelligent management, enhancing both security and convenience. However, with technological advancements, smart locks have gradually replaced traditional cabinet locks, becoming an important part of modern security. Among them, fingerprint locks, as a type of smart lock, are highly favored due to their high security and convenience.

[0003] Fingerprint locks unlock and close by recognizing and comparing a person's fingerprint. Their basic structure includes key components such as the lock body, fingerprint sensor, microprocessor, battery, and fingerprint database. When a user places their finger on the fingerprint sensor, the microprocessor quickly collects the fingerprint information and compares it with a template in the database. The lock only opens when the fingerprints match perfectly. This unlocking method greatly enhances the security and convenience of the lock.

[0004] However, despite the significant achievements of existing fingerprint locks in terms of security, convenience, and style, some shortcomings still need to be improved. Existing fingerprint locks are generally installed on perforated panels, but on some perforated panels, fingerprint locks can easily disrupt the overall aesthetic integrity of the lock. For example, because it is difficult to drill holes in glass to install fingerprint unlocking components, existing fingerprint locks are not easily installed on glass wine cabinets or glass doors, thus affecting the applicability and flexibility of fingerprint locks on glass structures, making them difficult to install and use conveniently. Furthermore, the lock body structure of existing fingerprint locks is relatively complex, and the drive control of its bolt is not easy to control, resulting in higher manufacturing costs, thus affecting the use and practicality of fingerprint locks. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a fingerprint lock for glass doors, so as to solve the technical problems in the background art that the existing fingerprint locks are not easy to install on glass doors, which affects the convenience and flexibility of fingerprint lock installation, and the existing lock tongue control structure has high manufacturing and use costs, which is not conducive to production and use.

[0006] The objective of this utility model is achieved through the following means:

[0007] A fingerprint lock for glass doors includes a housing, a bolt disposed on one side of the housing, and a fingerprint unlocker for controlling the bolt to unlock or lock. The housing has an internal cavity, and a slot communicating with the cavity is provided on the side of the housing. A cover is fitted onto the housing. A guide groove for mounting the bolt is formed within the cavity, with one end of the guide groove extending through the slot. The fingerprint unlocker is connected to the glass door via a connecting pad, which is positioned opposite to the housing and has a connecting hole for mounting the fingerprint unlocker. The fingerprint unlocker is electrically connected to a drive motor, which is located within the cavity. The drive end of the drive motor is connected to a cam drive block for driving the bolt to extend and retract along the guide groove. The bolt abuts against the cam drive block via a connecting part. A return spring is provided within the cavity for continuously providing elastic force to the bolt.

[0008] Furthermore, as described above, the latch is provided with an unlocked state and a locked state. In the unlocked state, when the drive motor generates power to drive the cam drive block to rotate, the cam drive block can drive the latch to retract and slide along the guide groove into the receiving cavity under the rotation and compression of the latch connection part. Conversely, when the drive motor is turned off, the latch slides along the guide groove and is exposed outside the groove opening by the reset spring force of the reset spring.

[0009] Furthermore, as described above, the drive motor is connected to one end of the cam drive block via a drive shaft, and the other end of the cam drive block has a protrusion that contacts the connecting part.

[0010] The cam drive block is eccentrically connected to the drive shaft, and contacts the connecting part through the protrusion on the cam drive block. Under the rotation of the cam drive block driven by the drive motor, the connecting part can slide along the guide groove through the contact between the protrusion and the connecting part. This allows the locking tongue to retract into the receiving cavity as it slides along the guide groove. Its drive control structure is simple, reducing manufacturing costs, and improving the convenience of assembly and connection.

[0011] Furthermore, as described above, the side of the locking tongue has a sliding portion, which is paired and installed in the guide groove, and the sliding portion has a connecting groove for installing a reset spring.

[0012] The reset spring provides a continuous elastic force to the latch, extending it outwards into the slot and thus locking it. Conversely, when the drive motor drives the latch to retract into the receiving cavity, the reset spring compresses, causing the latch to unlock.

[0013] Furthermore, as described above, a limiting protrusion is formed within the receiving cavity, and a connecting post is formed on the side of the limiting protrusion near the locking tongue. One end of the return spring is sleeved with the connecting post, and the other end of the return spring extends into the connecting groove.

[0014] The connecting groove and connecting post are used to mate and install the return spring, so that the return spring can be stretched or compressed along the axial extension direction of the guide groove.

[0015] Furthermore, as described above, the fingerprint unlocker has a fingerprint acquisition surface on its surface, and a fingerprint processor and a battery are disposed inside the fingerprint unlocker. The fingerprint processor is electrically connected to a charging interface, which is exposed on the surface of the fingerprint unlocker.

[0016] Furthermore, as described above, a protruding positioning post is provided inside the connection hole, and the back of the fingerprint unlocker is paired and inserted with the positioning post through the positioning hole.

[0017] Specifically, existing fingerprint locks can be installed by drilling holes in wooden boards, but drilling holes in glass boards is more difficult, making the installation and use of fingerprint unlockers more difficult. Therefore, by setting connecting pads, installation and use can be made more convenient.

[0018] The beneficial effects of this utility model are as follows: The guide groove formed in the receiving cavity provides a precise movement path for the lock tongue, ensuring the stability and accuracy of the lock tongue during unlocking or locking. The fingerprint unlocker is connected to the glass door through a connecting pad. The exemplary connecting pad is fixedly and adhesively installed on the glass door and positioned opposite the housing. The fingerprint unlocker is accurately positioned and installed in the connecting hole, reducing the drilling process on the glass door and improving the efficiency and applicability of installation and use. The electrically connected drive motor directly drives the lock tongue to extend and retract along the guide groove through a cam drive block, realizing a rapid response from fingerprint unlocking to lock tongue action. The lock tongue abuts against the cam drive block through the connecting part. This direct drive method reduces intermediate transmission links, lowers the failure rate, and thus improves unlocking efficiency. The reset spring set in the receiving cavity continuously provides elasticity to the lock tongue, ensuring that the lock tongue can automatically return to the locked state after unlocking. At the same time, the electric drive is more convenient and intelligent than the traditional mechanical method, improving the ease of use. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] In this embodiment, refer to Figures 1-4 A fingerprint lock for glass doors, specifically implemented therein, includes a housing 1, a bolt 2 disposed on one side of the housing 1, and a fingerprint unlocker 3 for controlling the bolt 2 to perform unlocking or locking actions. The housing 1 has an internal cavity 4, and a slot 5 communicating with the cavity 4 is provided on the side of the housing 1. A cover 6 is fitted onto the housing 1. A guide groove 7 for fitting the bolt 2 is formed within the cavity 4, with one end of the guide groove 7 extending through the slot 5. The fingerprint unlocker 3 is connected to the glass door via a connecting pad 8, which is positioned opposite to the housing 1 and has a connecting hole 9 for mounting the fingerprint unlocker 3. The fingerprint unlocker 3 is electrically connected to a drive motor 10, which is disposed within the cavity 4. The drive end of the drive motor 10 is connected to a cam drive block 11 for driving the bolt 2 to extend and retract along the guide groove 7. The bolt 2 abuts against the cam drive block 11 via a connecting part 12. A return spring 13 continuously provides elastic force to the bolt 2 is provided within the cavity 4.

[0026] The locking tongue 2 is provided with unlocked and locked states. In the unlocked state, when the drive motor 10 generates power to drive the cam drive block 11 to rotate, the cam drive block 11 can drive the locking tongue 2 to retract and slide along the guide groove 7 into the receiving cavity 4 under the rotation and pressing of the connecting part 12 of the locking tongue 2. Conversely, when the drive motor 10 is turned off, the locking tongue 2 slides along the guide groove 7 and is exposed outside the groove opening 5 by the reset elastic force of the reset spring 13.

[0027] The drive motor 10 is connected to one end of the cam drive block 11 via a drive shaft. The other end of the cam drive block 11 has a protrusion 14 that contacts the connecting part 12. The cam drive block 11 is eccentrically connected to the drive shaft and contacts the connecting part 12 through the protrusion 14. Under the rotation of the cam drive block 11 driven by the drive motor 10, the connecting part 12 can be pressed and slid along the guide groove 7 by the contact between the protrusion 14 and the connecting part 12. This allows the locking tongue 2 to retract into the receiving cavity 4 as it slides along the guide groove 7. The drive control structure is simple, reducing manufacturing costs and improving the convenience of assembly and use.

[0028] The side of the latch 2 has a sliding portion 15, which is installed in a guide groove 7. The sliding portion 15 has a connecting groove 16 for installing the return spring 13. The return spring 13 provides a continuous elastic force to the latch 2 to extend into the groove 5, so that the latch 2 is exposed outside the groove 5 and forms a locking action. Conversely, when the drive motor 10 drives the latch 2 to retract into the receiving cavity 4, the return spring 13 is compressed, so that the latch 2 forms an unlocking action.

[0029] A limiting protrusion 17 is formed within the receiving cavity 4. A connecting post 18 is formed on the side of the limiting protrusion 17 near the locking tongue 2. One end of the return spring 13 is sleeved with the connecting post 18, and the other end of the return spring 13 extends into the connecting groove 16. The connecting groove 16 and the connecting post 18 are used to mate and install the return spring 13, so that the return spring 13 can be stretched or compressed along the axial extension direction of the guide groove 7.

[0030] The fingerprint unlocker 3 has a fingerprint acquisition surface 19 on its surface. The fingerprint unlocker 3 has a fingerprint processor and a battery inside. The fingerprint processor is electrically connected to a charging interface 20, which is exposed on the surface of the fingerprint unlocker 3.

[0031] Specifically, the fingerprint processor contains key components such as a fingerprint acquisition unit and a fingerprint database. When a user places their finger on the fingerprint collector, the microprocessor quickly acquires the fingerprint information and compares it with the template in the database. The lock will only open when the fingerprints match perfectly. The specific control principle is a conventional technical method in this field and will not be described in detail here.

[0032] The use of bolts to assemble the cover 6 and the housing 1 enhances the structural stability of the lock, further protects the internal components, and improves the product's aesthetics and overall quality. It effectively prevents damage to these precision components from external environments such as moisture and dust, thereby extending the overall lifespan of the lock.

[0033] A protruding positioning post 21 is provided inside the connection hole 9. The back of the fingerprint unlocker 3 is paired and inserted with the positioning post 21 through the positioning hole. The positioning post 21 further improves the accurate positioning and installation of the fingerprint unlocker 3, and enhances the convenience and firmness of the connection.

[0034] The specific installation and usage in this embodiment are as follows:

[0035] The guide groove 7 formed within the receiving cavity 4 provides a precise movement path for the sliding part 15 of the latch 2, ensuring the smoothness and accuracy of the latch 2 during unlocking or locking. The latch 2 is paired with the guide groove 7 via the sliding part 15, and the side of the latch 2 is sleeved with the connecting post 18 via a return spring 13. The return spring 13 continuously provides elastic force to the latch 2, extending it towards the groove 5, so that the latch 2 forms an initial locked state. For example, in this embodiment, the fingerprint lock is applied to a wine cabinet glass door. Specifically, the connecting pad 8 is fixedly glued to the glass door and positioned opposite the housing 1, reducing the drilling process on the glass door and improving the efficiency and applicability of installation and use. The connecting pad 8 is installed on the surface of the glass door, and the housing 1 is installed on the back of the glass door. Fingerprint unlocking... The fingerprint unlocker 3 is accurately positioned and installed in the connection hole 9, improving the convenience of connecting the fingerprint unlocker 3, reducing the drilling on the glass door surface, and improving the overall aesthetics of the installation. At the same time, through fingerprint unlocking by the fingerprint processor, the electrically connected drive motor 10 directly drives the bolt 2 to retract along the guide groove 7 via the cam drive block 11, achieving a rapid response from fingerprint unlocking to bolt 2 action. The bolt 2 abuts against the cam drive block 11 through the connecting part 12, thereby controlling the unlocking of the bolt 2. After unlocking, within a set time, the drive motor 10 disconnects the driving force to the cam drive block 11, allowing the bolt 2 to return to the initial locked state under the return elasticity of the return spring 13. This direct drive method reduces intermediate transmission links, lowers the failure rate, and improves the convenience of use.
