[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This wireless infrared human body sensor for security uses a lifting mechanism. When the height of the detector needs to be adjusted, the lifting mechanism starts working. First, the motor starts, driving the threaded rod to rotate. Since the lifting block is located in the lifting groove and has a sliding hole on its inner wall, the threaded rod passes through the sliding hole. When the threaded rod rotates, the lifting block moves along the axial direction of the threaded rod in the lifting groove through the threaded transmission. At the same time, the slider connected to the lifting block slides on the surface of the limiting plate. The limiting groove opened inside the slider cooperates with the limiting plate to limit the direction of movement of the slider, ensuring that the lifting block can only move stably up and down in the vertical direction without deviation or rotation. In this way, by driving the threaded rod to rotate through the motor, the lifting block moves up and down, thereby realizing the height adjustment of the detector to meet the detection height requirements in different scenarios. At the same time, four electric universal wheels enable the detector to move in all directions, facilitating security monitoring in different locations. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a wireless infrared human body sensor for security, including a base plate 1, a shock absorber 2 on the bottom surface of the base plate 1, a connecting plate 3 fixedly connected to the bottom surface of the shock absorber 2, an electric universal wheel 4 installed on the bottom surface of the connecting plate 3, a lifting mechanism 5 on the upper surface of the base plate 1, an installation mechanism 6 on the surface of the lifting mechanism 5, a rotator 7 on the surface of the installation mechanism 6, a detector 8 fixedly connected to the upper surface of the rotator 7, a charging interface 9 on one side surface of the detector 8, an infrared sensor 10 on the surface of the detector 8, an alarm light 11 on the surface of the detector 8, an alarm 12 on the surface of the detector 8, and a glass cover 13 rotatably connected to the surface of the detector 8.
[0022] The lifting mechanism 5 includes a column 501, a lifting groove 502, a motor 503, a threaded rod 504, a lifting block 505, a sliding hole 506, a limiting plate 507, a slider 508, and a limiting groove 509. The column 501 is fixedly connected to the upper surface of the base plate 1. The column 501 has a lifting groove 502 inside. The motor 503 is fixedly connected to the bottom surface of the inner wall of the lifting groove 502. A threaded rod 504 is fixedly connected to one end of the motor 503. The lifting block 505 is slidably connected to the inner wall of the lifting groove 502. A sliding hole 506 is provided in the inner wall of the lifting block 505. A limiting plate 507 is fixedly connected to one side surface of the column 501. A slider 508 is slidably connected to the surface of the limiting plate 507. A limiting groove 509 is provided inside the slider 508. One end of the slider 508 is fixedly connected to the surface of the lifting block 505. Through the setting of the lifting mechanism 5, when it is necessary to adjust the height of the detector, the lifting mechanism... 5. To begin operation, motor 503 starts, driving threaded rod 504 to rotate. Since lifting block 505 is located within lifting groove 502 and has sliding hole 506 on its inner wall, threaded rod 504 passes through sliding hole 506. When threaded rod 504 rotates, lifting block 505 moves along the axial direction of threaded rod 504 within lifting groove 502 through threaded transmission. Simultaneously, slider 508 connected to lifting block 505 slides on the surface of limiting plate 507. Limiting groove 509 inside slider 508 cooperates with limiting plate 507 to restrict the direction of movement of slider 508, ensuring that lifting block 505 can only move stably up and down in the vertical direction without deviation or rotation. Thus, by driving threaded rod 504 to rotate through motor 503, lifting block 505 moves up and down, thereby achieving height adjustment of detector 8 to meet the detection height requirements in different scenarios.
[0023] Furthermore, multiple sets of shock absorbers 2 are symmetrically arranged on the bottom surface of the base plate 1, and electric casters 4 are symmetrically arranged at the four corners of the connecting plate 3 along the central axis of the connecting plate 3. Through the arrangement of shock absorbers 2 and electric casters 4, shock absorbers 2 can effectively reduce the impact force on the detector 8 during movement and when it is subjected to external vibrations, protecting the precision components inside the detector 8. When the detector 8 moves on uneven ground or encounters slight vibrations, shock absorbers 2 can absorb and buffer vibration energy to ensure the stability and accuracy of the detector 8. Electric casters 4 make the movement of the detector 8 more stable and flexible. The four electric casters 4 can evenly distribute the weight of the detector 8, ensuring that the detector 8 will not tilt or tip over during movement. At the same time, electric casters 4 can realize the omnidirectional movement of the detector 8, which is convenient for security monitoring in different positions.
[0024] Furthermore, the outer wall dimensions of the lifting block 505 match the inner wall dimensions of the lifting groove 502. The lifting block 505 slides up and down on the surface of the threaded rod 504 through the sliding hole 506. The lifting groove 502 and the lifting block 505 are designed to ensure that the lifting block 505 can only move vertically within the lifting groove 502 without shaking or shifting. This close fit makes the detector 8 more stable during the lifting process, improving the accuracy and reliability of the detector 8.
[0025] Furthermore, the slider 508 slides on the surface of the limiting plate 507 via the limiting groove 509, and the outer wall size of the slider 508 matches the inner wall size of the limiting groove 509. The setting of the slider 508 and the limiting groove 509 further enhances the stability of the lifting block 505 during the lifting process. The cooperation between the limiting plate 507 and the slider 508 restricts the rotational movement of the lifting block 505, making it only able to move in the vertical direction. This double limiting structure effectively prevents the lifting block 505 from shaking, tilting or deviating from the track during the lifting process, ensuring the safe operation of the detector 8.
[0026] Furthermore, the installation mechanism 6 includes an installation plate 601, a locking hole 602, a first telescopic spring 603, a stop block 604, a fixing rod 605, a telescopic hole 606, a second telescopic spring 607, a baffle 608, a limit block 609, and a fixing hole 610. The surface of the lifting mechanism 5 is provided with an installation plate 601, and the surface of the installation plate 601 has a locking hole 602. The outer wall surface of the locking hole 602 is fixedly connected to the first telescopic spring 603. The outer end surface of the first telescopic spring 603 is fixedly connected to the stop block 604. The inner side of the stop block 604 is fixedly connected to the fixing rod 605, and the inner wall surface of the fixing rod 605 has a telescopic hole 610. A second telescopic spring 607 is fixedly connected to one end of the inner wall of the telescopic hole 606. A baffle 608 is fixedly connected to one end of the surface of the second telescopic spring 607. A limit block 609 is fixedly connected to one end of the surface of the baffle 608. A fixing hole 610 is provided on the surface of the lifting mechanism 5. A mounting plate 601 is connected to the surface of the slider 508. A fixing hole 610 is provided on the inner surface of the slider 508. Through the setting of the mounting mechanism 6, when the detector 8 needs to be installed, the locking hole 602 on the mounting plate 601 is first aligned with the fixing hole 610 on the lifting mechanism 5. At this time, the fixing rod 605 is under the action of the first telescopic spring 603. When the mounting plate 601 is in the extended state, as it approaches the lifting mechanism 5, the end of the fixing rod 605 is compressed, causing it to move into the locking hole 602 and simultaneously compressing the first telescopic spring 603. As the mounting plate 601 continues to approach the lifting mechanism 5, when the fixing rod 605 aligns with the fixing hole 610, under the restoring force of the first telescopic spring 603, the fixing rod 605 inserts into the fixing hole 610, achieving initial fixation. At this time, the limiting block 609 located in the telescopic hole 606 inside the fixing rod 605 is in the extended state under the action of the second telescopic spring 607. When the fixing rod 605 inserts... After fixing the hole 610, the limiting block 609 will be pushed by the second telescopic spring 607 to further engage with the inner wall of the fixing hole 610, thereby strengthening the fixation. When it is necessary to disassemble the detector 8, the mounting plate 601 is pulled outward with force. The limiting block 609 on the fixing rod 605 will be squeezed by the inner wall of the fixing hole 610, causing the limiting block 609 to move into the telescopic hole 606, compressing the second telescopic spring 607. Continue to pull the mounting plate 601. When the fixing rod 605 is completely pulled out of the fixing hole 610, the disassembly of the detector 8 is completed. The detector 8 can then be installed in other places to achieve a flexible layout for security monitoring.
[0027] Furthermore, the outer wall dimension of the fixing rod 605 matches the inner wall dimension of the locking hole 602, and the outer wall dimension of the limiting block 609 matches the inner wall dimension of the fixing hole 610. Through the arrangement of the locking hole 602, fixing rod 605, limiting block 609, and fixing hole 610, the outer wall dimension of the fixing rod 605 matches the inner wall dimension of the locking hole 602, ensuring stable installation of the fixing rod 605 within the locking hole 602 without shaking or shifting. When the detector 8 is installed on the lifting device via the mounting mechanism 6... When the lowering mechanism 5 is in place, this tight fit allows the fixing rod 605 to be accurately inserted into the fixing hole 610, achieving a stable connection. The outer wall size of the limiting block 609 matches the inner wall size of the fixing hole 610, further enhancing the fixing effect of the mounting mechanism 6. After the fixing rod 605 is inserted into the fixing hole 610, the limiting block 609 is locked into the inner wall of the fixing hole 610 under the action of the second telescopic spring 607. This tight fit prevents the fixing rod 605 from accidentally coming out of the fixing hole 610.
[0028] Furthermore, multiple sets of alarm lights 11 are provided on the surface of the detector 8, and two sets of alarms 12 are symmetrically arranged around the central axis of the infrared sensor 10. Through the arrangement of alarm lights 11 and alarms 12, the alarm lights 11 can emit a strong visual warning signal when the detector 8 detects human activity. Multiple sets of alarm lights 11 can emit light from different angles, improving the visibility of the warning effect. The symmetrically arranged alarms 12 can enhance the sound propagation effect, so that the alarm sound can be clearly heard in all directions.
[0029] Working Principle: First, the base plate 1 serves as the foundation of the entire device. Multiple sets of shock absorbers 2 are symmetrically arranged on its bottom surface. When the detector 8 moves or is subjected to external vibrations, the shock absorbers 2 absorb and buffer the vibration energy, protecting the precision components inside the detector 8 and ensuring its stability and accuracy. Electric casters 4 are symmetrically arranged at the four corners of the connecting plate 3 at the bottom of the shock absorbers 2, making the movement of the detector 8 smoother and more flexible. The four electric casters 4 evenly distribute the weight of the detector 8, ensuring that the detector 8 will not tilt or tip over during movement, while also enabling omnidirectional movement of the detector 8 for convenient security monitoring in different locations. When the height of the detector 8 needs to be adjusted, the lifting mechanism 5 starts working. A lifting groove 502 is formed inside the column 501 on the upper surface of plate 1. A motor 503, fixedly connected to the bottom surface of the inner wall of the lifting groove 502, is activated, driving a threaded rod 504 to rotate. A lifting block 505, located within the lifting groove 502 and with a sliding hole 506 on its inner wall, moves along the axial direction of the threaded rod 504 within the lifting groove 502 through threaded transmission when the threaded rod 504 rotates. Simultaneously, a slider 508 connected to the lifting block 505 slides on a limiting plate 507 on one side surface of the column 501. A limiting groove 509 inside the slider 508 cooperates with the limiting plate 507 to restrict the movement direction of the slider 508, ensuring that the lifting block 505 can only move stably up and down in the vertical direction without deviation or rotation. To achieve height adjustment of the detector 8 and meet the detection height requirements in different scenarios, the detector 8 is mounted on the lifting mechanism 5 via the mounting mechanism 6. The locking hole 602 on the mounting plate 601 is aligned with the fixing hole 610 on the lifting mechanism 5. The fixing rod 605 is in an extended state under the action of the first telescopic spring 603. When the mounting plate 601 approaches the lifting mechanism 5, the end of the fixing rod 605 is squeezed and moves into the locking hole 602, while simultaneously compressing the first telescopic spring 603. As the mounting plate 601 continues to approach the lifting mechanism 5, when the fixing rod 605 is aligned with the fixing hole 610, under the restoring force of the first telescopic spring 603, the fixing rod 605 is inserted into the fixing hole 610 to achieve initial fixation. At this time, the fixing rod 605 is positioned... The limiting block 609 in the internal telescopic hole 606 is extended under the action of the second telescopic spring 607. When the fixing rod 605 is inserted into the fixing hole 610, the limiting block 609 will be further inserted into the inner wall of the fixing hole 610 under the push of the second telescopic spring 607, which will strengthen the fixation. When it is necessary to disassemble the detector 8, pull the mounting plate 601 outward with force. The limiting block 609 on the fixing rod 605 will be squeezed into the telescopic hole 606 by the inner wall of the fixing hole 610, compressing the second telescopic spring 607. Continue to pull the mounting plate 601. When the fixing rod 605 is completely pulled out of the fixing hole 610, the disassembly of the detector 8 is completed. The detector 8 can be installed in other places to realize a flexible layout of security monitoring.The rotator 7 on the surface of detector 8 can adjust the angle of detector 8. An infrared sensor 10 on the surface of detector 8 detects human activity. When a human is detected, multiple sets of alarm lights 11 on the surface of detector 8 emit strong visual warning signals, emitting light from different angles to improve the visibility of the warning effect. Two sets of alarms 12, symmetrically arranged around the central axis of the infrared sensor 10, emit loud audible alarms, enhancing the sound propagation effect so that the alarm sound can be clearly heard in all directions. A charging port 9 on one side of the surface of detector 8 is used to charge detector 8. A glass cover 13 rotatably connected to the surface of detector 8 protects the internal components of detector 8. The motor 503 is model Y315S-2. This completes the usage process of a wireless infrared human body sensor for security.
