Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensors, and in particular to a non-contact human infrared intelligent sensing sensor. Background Technology
[0002] Non-contact infrared intelligent human body sensors are intelligent devices based on infrared detection technology that can detect the presence and movement of a person by sensing the infrared radiation emitted by the human body without direct contact. With their non-contact nature, high sensitivity, and fast response speed, they are widely used in various scenarios such as residential buildings, commercial buildings, and offices. Examples include automatic lighting control and security alarm triggering in smart home systems, and energy-saving management in public areas.
[0003] However, traditional non-contact infrared human body sensors have certain limitations in installation and use. These sensors are typically mounted on walls or other surfaces using screws or adhesive. While this ensures stable installation, the sensor's position is fixed after installation, making it impossible to flexibly adjust to actual usage needs. Specifically, when the installation position deviates, causing the sensor's detection range to fail to cover the target area, or when the usage scenario changes (such as room layout adjustments or relocation of the target area), requiring a change in the sensor's installation position to adapt to the new needs, the fixed nature of traditional installation methods often necessitates removing the original sensor and reinstalling it. This process is not only cumbersome and may cause secondary damage to the mounting surface (such as screw hole residue or difficult-to-remove adhesive traces), but it also increases user costs and time, affecting the sensor's ease of use and flexibility. Therefore, this application proposes a non-contact infrared human body sensor to solve the above problems. Utility Model Content
[0004] The main objective of this invention is to provide a non-contact infrared intelligent human body sensor, which can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A non-contact infrared intelligent human body sensor includes a sensor body. A spherical connecting frame is fixedly installed at the rear end of the sensor body. The spherical connecting frame is mounted on a movable mounting plate. The movable mounting plate consists of a mounting plate body and positioning teeth. The positioning teeth are fixedly installed at the rear end of the mounting plate body. Two limiting members are symmetrically installed inside the mounting plate body. Each limiting member consists of a mounting guide rod and a fixing spring. The fixing spring is sleeved on the mounting guide rod. The movable mounting plate is mounted on a fixed plate. Connecting members are movably installed on the movable mounting plate, the limiting members, and the fixed plate. Each connecting member consists of a T-shaped slider and a protruding plate. There are two protruding plates, which are symmetrically fixedly installed at the front end of the T-shaped slider.
[0007] Preferably, the sensor body is provided with a charging port and control buttons.
[0008] Preferably, the front end of the fixing plate is symmetrically provided with four screw slots, and a T-shaped guide rail slot is provided between the four screw slots at the front end of the fixing plate. A plurality of locking tooth slots are evenly provided on the side end face of the fixing plate.
[0009] Preferably, the front end of the mounting plate body on the movable mounting plate is provided with a spherical groove, the mounting plate body is mounted on the spherical connecting frame through the spherical groove, and two connecting grooves are symmetrically provided on the mounting plate body on the upper and lower sides of the spherical groove. The connecting grooves pass through the mounting plate body from front to back, and the positioning teeth are engaged in the tooth grooves provided on the side end face of the fixed plate.
[0010] Preferably, the mounting guide rod on the limiting member is fixedly installed in the connecting groove opened on the mounting plate body.
[0011] Preferably, the T-shaped slider on the connector is slidably installed in the T-shaped guide groove opened at the front end of the fixed plate, the protruding plate is slidably installed in the connecting groove opened on the main body of the mounting plate, the protruding plate is provided with a mounting hole, the protruding plate is movably sleeved on the mounting guide rod on the limiting member through the mounting hole, and the protruding plate is also located inside the fixed spring.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] By setting up a movable mounting plate consisting of a mounting plate body and positioning teeth, a spherical connecting bracket fixedly mounted at the rear end of the sensor body is installed on the movable mounting plate. Simultaneously, a limiting component consisting of a mounting guide rod and a fixing spring is installed within the movable mounting plate.

A connecting component consisting of a T-shaped slider and a protruding plate is movably installed on the movable mounting plate, the limiting component, and the fixed plate. This allows the sensor body to be flexibly adjusted in position after installation. Specifically, the movable mounting plate engages with the positioning teeth in the tooth grooves on the fixed plate. Combined with the sliding of the T-shaped slider in the T-shaped guide groove of the connecting component, the position of the sensor body can be easily adjusted. After adjustment, the elastic force of the fixing spring on the limiting component ensures that the positioning teeth are stably engaged in the tooth grooves, guaranteeing a stable position for the sensor body after adjustment. Ultimately, when the installation position deviates or the usage scenario changes, there is no need to disassemble and reinstall, avoiding secondary damage to the mounting carrier, reducing user operating costs and time costs, and greatly improving the convenience and flexibility of using the sensor body.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figure 1 - Figure 6 As shown, a non-contact human infrared intelligent sensing sensor includes a sensor body 1. A spherical connecting frame 2 is fixedly installed at the rear end of the sensor body 1. The spherical connecting frame 2 is mounted on a movable mounting plate 3. The movable mounting plate 3 consists of a mounting plate body 9 and positioning teeth 20. The positioning teeth 20 are fixedly installed at the rear end of the mounting plate body 9. Two limiting members 4 are symmetrically installed inside the mounting plate body 9. The limiting members 4 consist of a mounting guide rod 12 and a fixing spring 13. The fixing spring 13 is sleeved on the mounting guide rod 12. The movable mounting plate 3 is mounted on a fixed plate 5. Connecting members 6 are movably installed on the movable mounting plate 3, the limiting members 4, and the fixed plate 5. The connecting members 6 consist of a T-shaped slider 17 and a protruding plate 18. There are two protruding plates 18, which are symmetrically fixedly installed at the front end of the T-shaped slider 17. By setting the movable mounting plate 3, which consists of the mounting plate body 9 and the positioning teeth 20, the spherical connecting frame 2 fixedly installed at the rear end of the sensor body 1 is mounted on the movable mounting plate 3. At the same time, within the movable mounting plate 3... A limiting member 4 consisting of a mounting guide rod 12 and a fixing spring 13 is provided, and a movable mounting plate 3 is mounted on a fixed plate 5. A connecting member 6 consisting of a T-shaped slider 17 and a protruding plate 18 is movably mounted on the movable mounting plate 3, the limiting member 4, and the fixed plate 5, so that the position of the sensor body 1 can be flexibly adjusted after installation. Specifically, the movable mounting plate 3 engages with the tooth groove 14 on the fixed plate 5 through the positioning tooth 20, and the T-shaped slider 17 of the connecting member 6 slides in the T-shaped guide groove 15, so that the position of the sensor body 1 can be easily adjusted. After adjustment, the elastic force of the fixing spring 13 on the limiting member 4 will cause the positioning tooth 20 to be stably locked in the tooth groove 14, ensuring that the position of the sensor body 1 is stable after adjustment. Finally, when the installation position deviates or the later use scenario changes, there is no need to disassemble and reinstall, avoiding secondary damage to the installation carrier, reducing the user's use cost and time cost, and greatly improving the convenience and flexibility of the sensor body 1.
[0023] Specifically, the sensor body 1 is equipped with a charging port 7 and a control button 8. The front end of the fixing plate 5 has four symmetrically arranged screw slots 16. A T-shaped guide rail slot 15 is also provided between the four screw slots 16. Several locking tooth slots 14 are evenly arranged on the side surface of the fixing plate 5. The front end of the mounting plate body 9 on the movable mounting plate 3 has a spherical groove 11. The mounting plate body 9 is mounted on the spherical connecting frame 2 via the spherical groove 11. Two connecting slots 10 are symmetrically arranged on the mounting plate body 9 on the upper and lower sides of the spherical groove 11. The connecting slots 10 pass through the mounting plate body 9 from front to back. Positioning locking teeth 20 are engaged in the locking tooth slots 14 on the side surface of the fixing plate 5. The mounting guide rod 12 on the limiting member 4 is fixedly installed in the connecting groove 10 opened on the mounting plate body 9. The T-shaped slider 17 on the connecting member 6 is slidably installed in the T-shaped guide rail groove 15 opened at the front end of the fixed plate 5. The protruding plate 18 is slidably installed in the connecting groove 10 opened on the mounting plate body 9. The protruding plate 18 has a mounting hole 19. The protruding plate 18 is movably sleeved on the mounting guide rod 12 on the limiting member 4 through the mounting hole 19. The protruding plate 18 is also located inside the fixed spring 13. The working principle of the sensor body 1 is that the sensor body 1 senses the infrared radiation emitted by the human body. When the presence or movement of the human body is detected, the internal circuit triggers a corresponding signal. An internal battery is installed, and the charging port 7 is used to charge the battery inside the sensor body 1, thereby realizing non-contact detection of the human body status. The spherical connecting bracket 2 can rotate within the spherical groove 11 to adjust the angle of the sensor body 1. Depending on the different force requirements of the actual use scenario, a fixed spring 13 of corresponding diameter must be selected to ensure that it has suitable elastic potential energy. The fixed spring 13 always applies a continuous and stable elastic force to the movable mounting plate 3 and the limiting member 4, forcing the positioning teeth 20 to be tightly engaged in the tooth groove 14. Even if the device encounters slight external vibration, collision or other sudden external force interference, this force can effectively offset the influence of external force and prevent the positioning teeth 20 from being damaged by external forces. Force impact prevents accidental disengagement from the tooth groove 14, thus ensuring that the movable mounting plate 3 and the connected sensor body 1 are always in a stable preset position, avoiding the impact of positional deviation on detection accuracy; the overall dimensions of the tooth groove 14 and the positioning tooth 20 are strictly matched to ensure that the contact surfaces are tightly fitted when they are engaged, without any loose gaps, thus structurally eliminating the shaking problem caused by the fit gap. At the same time, the tooth pitch, tooth width and other size parameters of the tooth groove 14 and the positioning tooth 20 can be flexibly set according to the actual adjustment accuracy requirements. If high-precision adjustment is required, the tooth pitch and the size of a single tooth can be reduced to make the adjustment range more precise. If the focus is on rapid coarse adjustment, the tooth pitch and the size of a single tooth can be increased to improve adjustment efficiency.
[0024] During installation, first pass the screw through the screw slot 16 on the fixing plate 5, and then screw the screw onto the mounting carrier. At this time, the fixing plate 5 will be fixedly installed on the mounting carrier, thus completing the installation of the non-contact human infrared intelligent sensing sensor. When the installation position of the non-contact human infrared intelligent sensing sensor deviates or the usage scenario changes later, the position of the sensor body 1 can be adjusted. The method is to first pull the movable mounting plate 3 to one side, so that the positioning teeth 20 disengage from the tooth slot 14. At this time, the mounting plate body 9 and the protruding plate 18 will fix the sensor body 1. The fixed spring 13 is compressed, and then the T-shaped slider 17 of the connector 6 is pushed to slide in the T-shaped guide groove 15 through the movable mounting plate 3. At this time, the spherical connecting frame 2 and the sensor body 1 will move with the movable mounting plate 3. When the position of the sensor body 1 is appropriate, the movable mounting plate 3 is slowly released. At this time, under the elastic force of the fixed spring 13, the movable mounting plate 3, the spherical connecting frame 2 and the sensor body 1 will be reset and pushed, so that the positioning teeth 20 on the movable mounting plate 3 will be re-engaged into the corresponding tooth groove 14, thereby completing the position adjustment of the sensor body 1.
[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
