Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to an anti-pry structure and a fully automatic door lock. Background Technology

[0002] Door locks are security devices used to lock doors and prevent unauthorized entry. With the development of intelligent technology, smart door locks have integrated functions such as identity recognition and remote control in addition to basic locking functions. Their core protection objects include not only the safety of door opening and closing, but also the anti-slip mechanism of the lock itself.

[0003] The anti-displacement element is a core module in smart locks that integrates key functions and valuable components. It typically includes valuable components such as a smart panel, main control chip, and communication module. If the anti-displacement element is pried, disassembled, or moved away from the door, it will not only cause the lock to fail, but also damage or loss of valuable components. Therefore, the anti-displacement protection of the anti-displacement element is a core aspect of the security design of smart locks.

[0004] Current anti-pry solutions for anti-displacement bodies are mainly applicable to exposed smart locks (the main body of the lock body is exposed on the outside of the door panel, and the lock shell is directly attached to the surface of the door panel): Usually, a push-button switch is installed on the back of the anti-displacement body as a trigger component. After the anti-displacement body and the lock shell are assembled, the push-button switch is pressed by the contact surface between the lock shell and the anti-displacement body; if the anti-displacement body is pried and detached from the lock shell, the push-button switch loses its pressing force and rebounds, thereby triggering the alarm.

[0005] However, this solution has significant compatibility issues in embedded smart lock scenarios. The lock body of an embedded smart lock needs to be fully embedded into a pre-set cavity in the door panel, and its installation environment is fundamentally different from that of an exposed smart lock. The anti-displacement body of an exposed smart lock can obtain stable clamping force through the rigid fit between the lock body and the door panel, while the anti-displacement body of an embedded smart lock is surrounded by a cavity in the door panel, lacking a rigid support surface for the push-button switch to form a "press-rebound" trigger logic. Specifically, after installation, the push-button switch cannot form an effective support with the lock body or door panel to trigger the push-button switch [A1]. Even if the anti-displacement body is illegally pried or moved, the switch is difficult to achieve effective rebound, causing the anti-displacement alarm function to completely fail. If a support structure is forcibly added in the cavity of the door panel to adapt to the push-button switch, it will break the original design intention of the embedded lock to "hide installation and save space". Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose an anti-pry structure and a fully automatic door lock to solve the problems mentioned in the background section above.

[0007] This utility model is achieved through the following technical solution: An anti-pry structure includes an anti-displacement body; the anti-displacement body includes a housing assembly, a PCB board built into the housing assembly, and a swinging member swayably connected to the housing assembly, one end of the swinging member extending out of the side end face of the housing assembly; the PCB board is provided with a trigger switch, and also includes an alarm communicatively connected to the trigger switch; by pressing one end of the swinging member protruding from the housing assembly, the other end of the swinging member is switched from a non-trigger position to a trigger position; when the swinging member is in the trigger position, the other end of the swinging member abuts against the trigger switch, causing the alarm to be in a non-operating state; when the swinging member is in the non-trigger position, the other end of the swinging member disengages from the trigger switch, causing the alarm to be in an operating state.

[0008] Furthermore, the ornament includes a trigger part and an outer extension part. The trigger part is used to abut against the trigger switch, and the outer extension part is disposed outside the housing assembly. By pressing the outer extension part, the trigger part is kept abutting against the trigger switch.

[0009] Furthermore, the ornament also includes a first connecting portion and a transition portion connecting the first connecting portion and the outer extension portion. The first connecting portion and the outer extension portion are arranged in a V-shape. The housing assembly accommodates the clearance groove of the transition portion, and the ornament swings in the clearance groove.

[0010] Furthermore, the ornament also includes a second connecting part, which is arranged in a V-shape with the first connecting part, and the trigger part is arranged in a V-shape with the second connecting part.

[0011] Furthermore, the PCB board is provided with a limiting groove for restricting the swing path of the trigger part.

[0012] Furthermore, when the outer extension abuts against the outer wall of the housing assembly, the ornament is in the trigger position.

[0013] Furthermore, the ornament is a one-piece molded plate structure.

[0014] Furthermore, the ornament is made of a feasible variable material.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figures 1 to 5 As shown, an anti-pry structure includes an anti-displacement body 1; the anti-displacement body 1 includes a housing assembly 11, a PCB board 13 built into the housing assembly 11, and a swing member 12 swayably connected to the housing assembly 11, one end of the swing member 12 extending out of the side end face of the housing assembly 11; the PCB board 13 is provided with a trigger switch 14, and also includes an alarm communicatively connected to the trigger switch 14; by pressing one end of the swing member 12 protruding from the housing assembly 11, the other end of the swing member 12 is switched from a non-trigger position to a trigger position; Reference Figure 3 As shown, when the ornament 12 is in the trigger position, the other end of the ornament 12 abuts against the trigger switch 14, so that the alarm is in a non-working state; Reference Figure 4 As shown, when the ornament 12 is in the non-triggered position, the other end of the ornament 12 is disengaged from the trigger switch 14, so that the alarm is in working condition.

[0025] The communication connection between the trigger switch 14 and the alarm (not shown in the figure) is existing technology. Existing communication connection technologies can be divided into wired communication technology and wireless communication technology according to the signal transmission method. Wired communication technology can use wires for connection, while wireless communication technology includes radio frequency wireless communication, Bluetooth communication, Wi-Fi communication, etc.

[0026] When the trigger switch 14 of the ornament 12 keeps the internal contacts of the trigger switch 14 open, the alarm circuit (not shown in the figure) is cut off and the alarm is in a non-working state. Once the anti-movement body 1 is pried or moved outward, the pushing action of the lock housing 2 on the ornament 12 disappears, the trigger switch 14 is reset, the alarm circuit is connected, and the alarm is in a working state. The alarm can notify the user that the anti-movement body 1 is being illegally pried away by one or more means such as emitting a sound alarm or a wireless remote alarm signal.

[0027] The ornament 12 includes a trigger part 121 and an outer extension part 122. The trigger part 121 is used to abut against the trigger switch 14. The outer extension part 122 is disposed outside the housing assembly 11. By pressing the outer extension part 122, the trigger part 121 is kept abutting against the trigger switch 14. The outer extension part 122 extends out of the side end face of the housing assembly 11. During installation, the lock housing 2 is directly pressed against the outer extension part 122, and the trigger part 121 continuously abuts against the trigger switch 14, keeping the alarm in a non-operating state.

[0028] The ornament 12 further includes a first connecting portion 123 and a transition portion 124 connecting the first connecting portion 123 and the outer extension portion 122. The first connecting portion 123 and the outer extension portion 122 are arranged in a V-shape. The housing assembly 11 makes way for the clearance groove 111 of the transition portion 124, and the ornament 12 swings in the clearance groove 111.

[0029] The transition portion 124 is embedded in the relief groove 111. The first connecting portion 123, which is arranged in a V-shape, and the outward extension can prevent the transition portion 124 from disengaging from the relief groove 111. The transition portion 124 constitutes a hidden pivot, eliminating the need for additional pins or metal bushings as pivots. The swing piece 12 swings back and forth around the transition portion 124, thereby switching the swing piece 12 between the non-triggered position and the triggered position, simplifying the installation process and the number of parts used.

[0030] Specifically, the housing assembly 11 includes a first housing 112 and a second housing 113 connected to each other. The mating portions of the first housing 112 and the second housing 113 are provided with notches, which form the clearance groove 111.

[0031] The ornament 12 also includes a second connecting portion 125, which is arranged in a V-shape with the first connecting portion 123, and the trigger portion 121 is also arranged in a V-shape with the second connecting portion 125. Through this arrangement, when subjected to external pressure, the V-shaped arrangement creates an elastic deformation space, allowing the slight deformation of the ornament 12 when the outer extension 122 is pressed to better maintain the pressed trigger switch 14.

[0032] The PCB board 13 is provided with a limiting groove 131 for restricting the swing path of the trigger part 121. Specifically, the free end of the trigger part 121 is embedded in the limiting groove 131, thereby restricting the movement path of the trigger part 121. When the swing member 12 repeatedly switches between the non-trigger position and the trigger position, the trigger part 121 can move along the preset path, so that the trigger part 121 correctly abuts against the trigger switch 14.

[0033] The lock housing 2 is pressed directly onto the outer extension 122. When the outer extension 122 abuts against the outer wall of the housing assembly 11, the swing member 12 is in the trigger position.

[0034] When the connecting part abuts against the inner wall of the housing assembly 11, the ornament 12 is in the non-triggered position due to the force of the trigger switch 14 and gravity.

[0035] In the above embodiments, the inner and outer walls of the housing assembly 11 directly serve as the limiting structure for the swing angle of the pendulum 12, preventing the pendulum 12 from overswing or insufficiently rebounding. Furthermore, changing the point or line contact between the housing assembly 11 and the pendulum 12 to a surface contact helps to reduce the unit area load of the pendulum 12 and improve the service life of the pendulum 12.

[0036] The ornament 12 is a one-piece molded plate structure, and the ornament 12 is made of a flexible material. The ornament 12 is made by stamping or injection molding a single piece of metal plate or reinforced plastic in one go, without secondary welding, which is conducive to mass production. Furthermore, by utilizing the flexibility of the material itself, it ensures that the trigger part 121 better retains the press trigger switch 14.

[0037] On the other hand, this utility model also provides a fully automatic door lock, which includes a lock housing 2 and an anti-displacement body 1 as described in any of the above claims. The lock housing 2 is provided with a mounting groove 21 for inserting the housing assembly 11, and the lock housing 2 is provided with a support portion 22 for keeping the swing member 12 abutting against the trigger switch 14. When the anti-displacement body 1 is inserted into place, the support portion 22 abuts against the outer extension portion 122 from the side, making installation and operation simple.

[0038] The ornament 12 also includes a snap-fit ​​part 126 disposed on the upper end of the support part 22, which is fastened to the upper end of the support part 22 by the snap-fit ​​part 126, further limiting the position of the ornament 12.

[0039] A sealing gasket 3 is provided between the snap-fit ​​part 126 and the anti-displacement body 1. The sealing gasket 3 prevents moisture, dust and other substances from entering the anti-displacement body 1 and causing damage to its internal electronic components. The sealing gasket 3 is made of materials including but not limited to rubber, sponge and other materials.
