Detailed Implementation

[0020] Example: A burglar alarm device with a pressure sensor, such as... Figures 1-6As shown, the device includes a window 1, mounting blocks 2, an alarm 3, guide rods 4, springs 5, a pressure sensor body 6, a vibration sensor 7, a connecting frame 8, connecting blocks 9, blades 10, a drive assembly, a protective shell 19, and a controller 20. Two mounting blocks 2 are vertically bolted to the front of the window 1. The alarm 3 is bolted to the middle of the top of the upper mounting block 2. The protective shell 19 is also bolted to the middle of the top of the upper mounting block 2 and covers the alarm 3, providing mechanical protection. The protective shell 19 has multiple sound-permeable holes on all four sides to ensure that the sound and light signals emitted by the alarm 3 can effectively penetrate and achieve clear sound and light alarm prompts. Two symmetrically distributed guide rods 4 are fixedly connected inside each mounting block 2. A connecting block 9 is slidably installed on the outside of each guide rod 4. The four connecting blocks 9 are bolted together by a connecting frame 8. A spring 5 is sleeved on the outside of each guide rod 4, and the front and rear ends of the spring 5 are respectively connected to the corresponding connecting blocks. 9 and the corresponding mounting block 2 are fixedly connected, providing a reset force for the connecting block 9 and the connecting frame 8. Multiple blades 10 are equidistantly distributed inside the connecting frame 8. The blades 10 are initially tilted. When all blades 10 are rotated to a vertical state, they can completely close the transparent area of ​​the connecting frame 8, achieving visual obstruction and preventing external peeping. A pressure sensor body 6 is bolted to each of the four corners at the front of the window 1. The connecting frame 8 is located in front of the pressure sensor body 6, and its rear surface contacts the pressure-bearing surface of the pressure sensor body 6. A vibration sensor 7 is bolted to each of the left and right sides at the front of the window 1. The connecting frame 8 is also located in front of the vibration sensor 7. The controller 20 is bolted to the left rear of the window 1. The alarm 3, the pressure sensor body 6, and the vibration sensor 7 are all electrically connected to the controller 20. The controller 20 has a built-in wireless communication module that can send alarm information to the user's mobile phone. The drive component is located inside the connecting frame 8.

[0021] like Figure 4 and Figure 5As shown, the drive assembly includes a crank 11, a connecting rod 12, a locking plate 121, a guide rail 13, a sliding plate 14, a lead screw 15, a bearing 16, a mounting plate 17, and a motor 18. Each blade 10 has a crank 11 fixedly connected to its left end. A connecting rod 12 is rotatably connected between multiple cranks 11. A locking plate 121 is fixedly connected to the upper end of the connecting rod 12. The guide rail 13 is bolted to the upper left side of the connecting frame 8, and a sliding plate 14 slides on it, inserting into the locking plate 121. Similarly, the mounting plate 17 is bolted to the upper left side of the connecting frame 8, and the motor 18 is bolted to the mounting plate 17. Its output shaft extends vertically downward and is fixedly connected to a lead screw 15 via a coupling. The lead screw 15 passes through the slide plate 14 and is threadedly engaged with it. The motor 18 is electrically connected to the controller 20 and is a stepper motor with a self-locking function. When the power is off, it can automatically lock the rotor position to prevent external force from driving the lead screw 15 to rotate, thereby maintaining the current state of the blade 10. The bearing seat 16 is also bolted to the upper left side of the inner part of the connecting frame 8 and is located below the motor 18. The lower end of the lead screw 15 passes through the bearing seat 16 and rotates with it to enhance the stability of the lead screw 15 during rotation, prevent radial sway, and ensure smooth and reliable transmission.

[0022] In normal conditions, the blades 10 are arranged at an angle to maintain the ventilation and lighting functions of window 1. When the user needs to go out, the controller 20 starts the preset blade 10 closing program. After the program starts, the motor 18 runs automatically, and its output shaft drives the lead screw 15 to rotate clockwise, driving the slide plate 14 to slide upward along the guide rail 13. The slide plate 14 drives the connecting rod 12 to move through the snap plate 121, which in turn drives the crank 11 to rotate, so that the blades 10 rotate from the inclined state to the vertical closed position, completely sealing the transparent area of ​​the connecting frame 8, forming a continuous visual barrier, effectively preventing outsiders from peeping into the interior layout and personnel activities. After the blades 10 are closed in place, the motor 18 automatically shuts off.

[0023] If someone attempts to pry, hit, or climb window 1, the connecting frame 8 will move, the spring 5 will deform, the pressure sensor body 6 will detect abnormal pressure changes, or the vibration sensor 7 will sense violent vibrations. The signal will be immediately transmitted to the controller 20, which will control the alarm 3 to issue an audible and visual alarm and send alarm information to the user's mobile phone via the built-in wireless module, thus realizing proactive early warning and remote linkage.
