Description

Technical Field

[0001] The utility model belongs to the technical field of glass door locks, and in particular relates to a protective chamber structure of a glass door lock. Background Art

[0002] With the development of modern building technology and interior decoration, glass doors have become widely used in homes, offices, shopping malls, and other places due to their transparent and beautiful features. However, the safety of glass doors has always been a major concern. To improve the security of glass doors, glass door locks have become an indispensable component. To protect the electronic and mechanical components within glass door locks from external factors such as dust, moisture, and physical impact, a protective chamber is usually installed around the glass door lock.

[0003] The Chinese utility model patent application number is CN202222321347.9 (publication number is CN219118989U) discloses a glass door lock, including an outdoor unlocking controller, an indoor mechanical lock, an upper mounting plate, a lower mounting plate and a locking device. The outdoor unlocking controller is fixed to the upper mounting plate through the locking device; the unlocking controller synchronization wheel is connected to the motor drive device of the outdoor unlocking controller, the mechanical lock shaft synchronization wheel is installed on the rotating shaft of the indoor mechanical lock, the synchronous belt is sleeved on the unlocking controller synchronization wheel and the mechanical lock shaft synchronization wheel, the second magnet is attached to the upper surface of the mechanical lock shaft synchronization wheel, and the first magnet is attached to the lower surface of the unlocking controller synchronization wheel. When the locking device is opened, the outdoor unlocking controller can be separated from the upper mounting plate, so that the internal unlocking controller synchronization wheel and the first magnet are exposed. Rotating the unlocking controller synchronization wheel or the first magnet drives the mechanical lock shaft synchronization wheel of the indoor mechanical lock to rotate, thereby preventing the glass door lock from being broken.

[0004] These glass door locks often lack an effective emergency door opening mechanism when the electronic components malfunction, potentially trapping the user inside the door and posing a safety hazard. Therefore, while these glass door locks have improved safety and reliability to a certain extent, they still have significant deficiencies in terms of protection performance, emergency response capabilities, internal structure, and user experience, and are in urgent need of improvement and optimization.

After entering the protective compartment, the FPC film connects to the internal circuit board. The connection points are connected using soldering or a dedicated connector.

[0055] like Figure 3 As shown, in the above technical solution, the door lock body 10 and the card slot 20 are both metal slot parts with a U-shaped cross-section.

[0056] like Figure 5 、 Figure 6 、 Figure 7 As shown, further, in the above technical solution, the second magnetic steel 13 is inserted into the opening of the lower mounting plate 102 to control the rotation of the driving gear 32, thereby driving the second magnetic steel 13 to rotate and drive the gate plate 11 to extend and retract. Figure 7 Specifically, the second magnet is not connected to the driving gear, that is, the pin is not inserted into the groove.

[0057] Furthermore, in the above technical solution, the driving gear 32 is installed at the bottom of the protective chamber 31 and is connected to the output shaft of the motor.

The magnetic poles of the first magnet 12 and the second magnet 13 on the opposite surfaces are opposite, and the opening and closing states of the gate are switched by the action of the magnetic field.

[0062] Furthermore, in the above technical solution, the gate plate 11 is made of metal, installed in the protective chamber 31, and located below the driving gear 32 for cooperating with the card slot.

[0063] like Figure 4 、 Figure 9 As shown, further, in the above technical solution, the outdoor unlocking controller 104 includes a motor drive device, a display 1041, a keyboard 1042, a fingerprint sensor 1043 and a control chip 1044, and the display 1041, the keyboard 1042, the fingerprint sensor 1043, the motor drive device and the control chip 1044 are electrically connected.

[0064] The fingerprint sensor identifies the user's fingerprint signal and transmits the fingerprint signal to the control chip. After processing and comparison, the control chip controls the display to display the text of successful unlocking. The control chip controls the motor to rotate and drive the unlocking drive gear 04 to unlock; or enter the password on the keyboard, the keyboard will identify the password information and send it to the control chip. After processing and comparison, the control chip controls the display to display the text of successful unlocking. The control chip controls the motor to rotate and drive the unlocking drive gear to unlock.

[0065] It should be noted that the specific model specifications of the display, keyboard, fingerprint sensor, and control chip need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0066] Specifically, the principle of the present utility model is:

[0067] Principle of emergency door opening mechanism:

[0068] Interaction between the first and second magnets: This utility model utilizes the interaction between the first and second magnets to implement an emergency door opening mechanism. Normally, the first and second magnets attract each other, ensuring that the second magnet is inserted into the gate opening, keeping the door locked closed. In the event of an electronic failure, the first magnet is inserted from the inside of the door, repelling the second magnet and causing it to disengage from the gate slot. The gate can then be disengaged from the slot through the gap in the glass door, achieving emergency door opening.

[0069] Reverse insertion design of the first magnet: The reverse insertion design of the first magnet is simple and easy to use. The user only needs to reversely insert the first magnet into a specific position at the bottom of the protective compartment to change the interaction between the first and second magnets. This design is not only simple to operate but also highly reliable, ensuring the effectiveness of the emergency door opening mechanism.

[0070] Disengagement and movement of the gate: Once the second magnet is released from the gate slot, the gate can move freely under the action of the compression spring. The user can slide the gate from the gap in the glass door to release it from the slot, thereby opening the door. This process is simple and quick, allowing users to quickly and effectively open the door in an emergency, ensuring safety and convenience.

[0071] Internal structure optimization principle:

[0072] Compact design: This utility model optimizes the internal structure to make the layout of each component more compact and reasonable. The drive gear is installed in the center of the bottom of the protective chamber and is connected to the motor output shaft through a keyway to ensure the reliability and efficiency of power transmission. One end of the compression spring is fixed to the bottom of the protective chamber, and the other end is connected to the gate, providing the necessary reset force to ensure the normal operation of the gate. The position and connection relationship of the first magnet and the second magnet are optimized to ensure the maximization of the magnetic effect and improve the overall performance of the device.

[0073] Efficient power transmission: The drive gear is keyed to the motor output shaft, ensuring reliable and efficient power transmission. When the motor rotates, the reduction gear drives the drive gear, which in turn drives the gate to extend and retract, unlocking and locking. This optimized power transmission system ensures smooth and efficient power transmission, improving the overall performance of the device.

[0074] Easy Maintenance: The optimized internal structure facilitates repair and replacement of internal components. The protective compartment is quick and easy to remove and install, allowing users to easily inspect and maintain internal components. Furthermore, the optimized connection between components ensures easy removal and installation, reducing user costs.
