Description

Technical Field

[0001] This utility model relates to the field of intelligent security installation, and in particular to a vacuum suction cup installation device for fingerprint password locks adapted to glass doors. Background Technology

[0002] With the development of smart homes, fingerprint locks have been widely used due to their convenience and security. For glass doors such as those in shopping malls, offices, and home balconies, where traditional locks cannot be installed by drilling, vacuum suction cup installation has become an ideal non-destructive solution.

[0003] Currently, fingerprint locks designed for glass doors generally adopt a non-destructive installation solution using multi-point vacuum suction cups and atmospheric pressure difference. The fingerprint lock is directly attached to the surface of the glass door by multiple vacuum suction cups, which are usually installed at the bottom or around the lock body. Atmospheric pressure is used to achieve a stable fixation without drilling or damaging the door structure.

[0004] Existing technologies have significant shortcomings. First, their installation reliability relies entirely on the initial installation state and the physical integrity of the suction cup material. During use, the suction cup may experience a decrease in sealing performance due to aging, temperature deformation, or minor damage, leading to slow vacuum leakage and eventual pressure loss and detachment. This is a gradual process that is difficult for users to detect, posing a significant safety hazard. Second, there is no mechanical anti-detachment backup mechanism. The fixing method relies solely on atmospheric pressure difference, resulting in weak resistance to lateral shear forces. Under conditions of accidental impact, forced prying, or long-term vibration caused by frequent door opening and closing, there is a higher risk of detachment. Therefore, a vacuum suction cup installation device for fingerprint locks adapted to glass doors is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vacuum suction cup installation device for fingerprint locks adapted to glass doors, aiming to improve the problem that the existing vacuum suction cup installation devices for fingerprint locks adapted to glass doors lack intelligent linkage compensation inflation capability and mechanical anti-detachment backup mechanism, which increases the risk of detachment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum suction cup mounting device for fingerprint locks adapted to glass doors, comprising a mounting base, a connecting frame fixedly connected to the outer wall of the mounting base, a vacuum generator fixedly connected to the outer wall of the mounting base, a vacuum suction cup fixedly connected to the output end of the vacuum generator via a pipe, an anti-slip ring fixedly connected to the outer wall of the vacuum suction cup, a miniature air pressure sensor fixedly connected to the inner surface of the vacuum suction cup, an electric push rod fixedly connected to the outer wall of the connecting frame, a U-shaped clamp fixedly connected to the output end of the electric push rod, an anti-slip pad fixedly connected to the inner surface of the U-shaped clamp, an installation groove formed on the inner surface of the U-shaped clamp, a pressure sensor fixedly connected to the inner wall of the installation groove, and a through groove formed at the center of the anti-slip pad.

[0007] As a further description of the above technical solution:

[0008] The vacuum generator and vacuum suction cup are arranged in several groups, and the several groups of vacuum generators and vacuum suction cups are distributed at equal distances on both outer walls of the mounting substrate.

[0009] As a further description of the above technical solution:

[0010] The vacuum generator is fixedly connected to the outer wall of the mounting base near the connecting frame.

[0011] As a further description of the above technical solution:

[0012] Two sets of electric push rods are provided and are symmetrically arranged with the central axis of the connecting frame as the axis of symmetry. The electric push rods are fixedly connected to the outer wall of the connecting frame on the side near the vacuum generator.

[0013] As a further description of the above technical solution:

[0014] The anti-slip pad has anti-slip texture on the side away from the C-shaped clamp.

[0015] As a further description of the above technical solution:

[0016] The U-shaped sleeve is disposed on the outer wall of the mounting base plate.

[0017] As a further description of the above technical solution:

[0018] An extension block is fixedly connected to the outer wall of the mounting base plate, a guide groove is provided on the inner surface of the C-shaped clamp, a first reinforcing rib is fixedly connected to the outer wall of the C-shaped clamp, and a second reinforcing rib is fixedly connected to the outer wall of the C-shaped clamp.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the extension block is slidably connected to the inner wall of the guide groove. Several sets of reinforcing ribs 2 and 1 are provided, and the several sets of reinforcing ribs 2 and 1 are distributed in an interlaced grid pattern.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the vacuum suction cup and electric clamping mechanism are used for double fixation. Combined with an independently controlled vacuum generator and high-precision sensors, intelligent pressure compensation and dynamic adjustment of clamping force are achieved to ensure that the installation on the glass door is firm and reliable, with strong anti-interference ability and effectively preventing accidental loosening.

[0023] 2. In this utility model, the smooth and accurate clamping action is ensured by the precise sliding cooperation between the extension block and the guide groove, while the reinforcing rib structure with interlaced grid distribution improves the overall torsional strength and rigidity of the U-shaped clamp, making it less prone to deformation when bearing load, and enhancing the stability and durability of installation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a fingerprint lock vacuum suction cup mounting device adapted for glass doors, comprising a mounting base 1, a connecting frame 2 fixedly connected to the outer wall of the mounting base 1, mounting holes on the connecting frame 2 for fixing the fingerprint lock to the connecting frame 2, a vacuum generator 3 fixedly connected to the outer wall of the mounting base 1, the vacuum generator 3 having a built-in silencer to avoid noise pollution, the vacuum generator 3 fixedly connected to the outer wall of the mounting base 1 near the connecting frame 2, and a vacuum suction cup 4 fixedly connected to the output end of the vacuum generator 3 via a pipe, and several sets of vacuum generators 3 and vacuum suction cups 4 are provided, and several sets of vacuum generators 3 and vacuum suction cups 4 are provided. The suction cups are distributed on both outer walls of the mounting substrate 1, and adopt a multi-layer composite suction cup structure. Each suction cup is independently connected to a vacuum generator 3 and a miniature pressure sensor 6, which realizes partition sealing and independent monitoring. Even if one suction cup leaks slightly, the other suction cups can still maintain effective adsorption, which greatly improves the redundancy and reliability of the system. The outer wall of the vacuum suction cup 4 is fixedly connected to an anti-slip ring 5, and the inner surface of the vacuum suction cup 4 is fixedly connected to a miniature pressure sensor 6. The miniature pressure sensor 6 is set at the chip level and is used to directly detect the change in the vacuum degree inside the vacuum suction cup 4. The sensor needs to pass through the suction cup material through an extremely thin flexible circuit FPC and connect to the main control circuit on the substrate.

[0032] Reference Figures 2-4An electric push rod 7 is fixedly connected to the outer wall of the connecting frame 2. Two sets of electric push rods 7 are arranged symmetrically about the central axis of the connecting frame 2. The electric push rods 7 are fixedly connected to the outer wall of the connecting frame 2 on the side closest to the vacuum generator 3. A U-shaped clamp 8 is fixedly connected to the output end of the electric push rod 7. The electric push rod 7 drives the U-shaped clamp 8 to clamp the edge of the glass. During clamping, the pressure sensor 11 provides real-time data feedback. The PLC... The clamping force is corrected by adjusting the extension stroke of the electric push rod 7 to ensure stability and prevent damage to the glass. The C-shaped clamp 8 is sleeved on the outer wall of the mounting base plate 1. An anti-slip pad 9 is fixedly connected to the inner surface of the C-shaped clamp 8. The anti-slip pad 9 has anti-slip texture on the side away from the C-shaped clamp 8. An installation groove 10 is opened on the inner surface of the C-shaped clamp 8. A pressure sensor 11 is fixedly connected to the inner wall of the installation groove 10. A through groove 12 is opened through the center of the anti-slip pad 9. When the micro air pressure sensor 6 detects that the vacuum degree of the vacuum suction cup 4 drops to the threshold, the PLC immediately triggers the electric push rod 7 to increase the clamping force and at the same time starts the corresponding vacuum generator 3 to compensate for the pressure, so as to prevent the device from loosening.

[0033] Reference Figure 3 An extension block 13 is fixedly connected to the outer wall of the mounting base plate 1. A guide groove 14 is provided on the inner surface of the C-shaped clamp 8. The outer wall of the extension block 13 is slidably connected to the inner wall of the guide groove 14. The sliding surface is polished to reduce frictional resistance. A first reinforcing rib 15 and a second reinforcing rib 16 are fixedly connected to the outer wall of the C-shaped clamp 8. Several sets of second reinforcing ribs 16 and first reinforcing ribs 15 are provided, and the several sets of second reinforcing ribs 16 and first reinforcing ribs 15 are distributed in an interlaced grid pattern. The grid structure improves the torsional strength of the C-shaped clamp 8 and makes it less prone to deformation under stress.

[0034] Working Principle: The user attaches the device to the predetermined position on the glass door and starts the installation program via external commands, such as buttons, remote control, or APP. The vacuum generator 3 starts working, evacuating each vacuum suction cup 4. The miniature pressure sensor 6 monitors the air pressure value in each suction cup in real time. When the air pressure value reaches the first preset threshold, it is determined that the adsorption is firm, and the vacuum generator 3 stops working. After the adsorption is firm, the core processing unit sends a command to the electric push rod 7 to drive the U-shaped clamp 8 to close and clamp the edge of the glass door. The pressure sensor 11 monitors the clamping force in real time. When the clamping force reaches the preset safety value, the electric push rod 7 stops moving and enters the pressure holding state. The core processing unit continuously reads the data of each miniature pressure sensor 6. If the air pressure value of a certain suction cup is higher than the second preset threshold but lower than the danger threshold due to slow leakage, the core processing unit will activate the vacuum generator 3 corresponding to that suction cup to replenish the pressure until its air pressure returns to the first preset threshold. If the pressure sensor 11 detects that the clamping force is affected by vibration or When the temperature drops, the core processing unit will immediately activate the electric push rod 7 for fine-tuning, increasing the thrust to restore the clamping force to the preset safety value. If the miniature air pressure sensor 6 detects a rapid loss of pressure in a suction cup, such as from an impact or sudden damage, and the air pressure exceeds the danger threshold, the core processing unit will immediately execute the safety protocol. First, it will trigger all other vacuum generators 3 to operate at maximum power to attempt to maintain the overall vacuum level. At the same time, it will immediately increase the output power of the electric push rod 7 to increase the clamping force of the U-shaped clamp 8 to the maximum mechanical clamping force, using mechanical means as the primary fixing method. Simultaneously, it will send an alarm message to the user's mobile APP. This "electric-mechanical" linkage redundancy design greatly improves safety in extreme situations, realizing a leap from passive reliance to active monitoring, intelligent compensation, and redundant backup, improving the reliability and safety of installation. The core processing unit can use a low-power industrial-grade chip, which can be powered by the fingerprint lock's built-in battery or by a separate external power supply.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
