Description

Technical Field

[0001] This invention relates to the field of detector installation, and in particular to an active infrared detector installation structure and installation method. Background Technology

[0002] Active infrared detectors are specialized electronic devices in the field of infrared detection technology. Their core detection logic involves actively emitting an infrared detection beam, receiving the echo signal reflected from the target within the detection area, and identifying the target by analyzing the characteristic changes in the echo signal. Compared to passive infrared (PIR) detectors, which rely on the target's own thermal radiation for detection, active infrared detectors do not depend on the target's own temperature properties. They achieve detection by autonomously completing a closed loop of infrared light transmission and reception, and can operate stably in special scenarios such as low temperatures and zero temperature differences.

[0003] Chinese Patent (CN222503182U) discloses a mounting base structure for an infrared detector. The mounting base structure includes two support plates fixedly mounted on one side of two adjacent mounting plates. A fixing block is slidably mounted on the outer side of each of the two support plates. A first bolt is provided within each fixing block. A second fixing ear is fixedly mounted on the adjacent side of each of the two fixing blocks. A first fixing seat is provided on each of the two second fixing ears. First fixing ears are fixedly mounted on both sides of the first fixing seat. A second bolt is provided within both the first and second fixing ears. This mounting base structure for the infrared detector has the advantages of being simple to use, easy to disassemble and install, and capable of clamping the base. While current installation structures can complete the installation and assembly of detectors, the installation and positioning of detectors requires repeatedly loosening multiple sets of bolts, repeatedly comparing and calibrating the detection position, and then tightening them one by one. This is not only cumbersome and time-consuming, but also requires completely loosening all the locking bolts to readjust if the detection angle or position needs to be finely adjusted after installation. This can easily cause the calibrated detection benchmark to completely shift, making it impossible to achieve minute and precise adjustments to the detector position without damaging the original positioning benchmark. As a result, many field-deployed active infrared detectors are unable to be easily fine-tuned after installation, and are in a state of long-term detection window offset, affecting the false alarm rate of infrared detectors.

[0011] As a further description of the above technical solution, the installation mechanism includes a flip motor and a mounting box fixed to the output end of the flip motor. The flip motor is fixedly installed in a motor slot provided on one side of the moving block, and the motor slot is connected to several arc-shaped air guide slots through several air guide holes.

[0014] As a further description of the above technical solution, a positioning component is provided inside the bottom groove. The positioning component includes a longitudinal spring shaft, which is fixedly installed inside the bottom groove, and a positioning column is slidably installed outside the longitudinal spring shaft.

[0016] The present invention also discloses an installation method for an active infrared detector mounting structure, comprising the following steps:

[0017] S1. When installing the infrared detector, the entire installation structure can be moved to the installation area, and then the infrared detector can be installed on the above installation structure.

At this time, the side walking wheels can roll on the inner wall of the moving slot. At this time, several turbulence fan blades can rotate synchronously, and the generated airflow can be conducted to one side. Part of the airflow can blow out the dust outside the detector through several arc-shaped air guide slots, and another part of the airflow can be guided into the motor slot through the arc-shaped air guide slots to take away the heat accumulated in the motor slot.

[0021] In summary, the present invention has the following beneficial technical effects:

[0031] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0032] This invention discloses an active infrared detector mounting structure and mounting method, referring to... Figure 1 - Figure 2 The system includes a mounting frame 2 for fixed support, a mounting mechanism 5 for supporting the infrared detector, and a drive mechanism for driving the mounting mechanism 5 to complete vertical displacement. The mounting frame 2, as the basic support component of the entire structure, is integrally bent from high-strength aluminum alloy profiles, with an overall U-shaped cross-section, which can provide a stable mounting reference surface for all subsequent moving parts. One side of the mounting frame 2 has a complete installation space reserved for arranging the mounting mechanism 5. The drive mechanism is integrated within the frame space of the mounting frame 2. When the drive mechanism is running, it can directly drive the mounting mechanism 5 to make a stable vertical linear displacement along the extension direction of the mounting frame 2, without any additional transmission gaps throughout the process, ensuring the height adjustment accuracy of the infrared detector.

[0033] As a further optimization of the present invention, the drive mechanism consists of three parts: an adjusting motor 1, an adjusting screw 7, and a moving component 4. The adjusting motor 1 is a DC geared motor with a self-locking function, which is fixedly mounted on the top end face of the mounting bracket 2 by bolts. The output shaft of the adjusting motor 1 extends vertically downward. The adjusting screw 7 is coaxially fixed to the output end face of the adjusting motor 1 by a coupling. The bottom end of the adjusting screw 7 is rotatably mounted on the bottom end face of the mounting bracket 2 by a deep groove ball bearing to ensure the coaxiality of the adjusting screw 7 during operation. The moving component 4 is integrally injection molded from engineering plastic and metal inserts. The center position of the moving component 4 is reserved with an internal thread hole that is completely matched with the external thread of the adjusting screw 7. The moving component 4 is fully threaded onto the outer surface of the adjusting screw 7 through the internal thread hole. The side of the moving component 4 is fixedly connected to the side of the mounting mechanism 5 by bolts. When the adjusting motor 1 drives the adjusting screw 7 to rotate forward or reverse, the moving component 4 can complete a stable upward or downward movement along the axial direction of the adjusting screw 7.

[0034] Reference Figure 2 and Figure 3As a further optimization of the present invention, a rectangular movable groove 6 is provided on the inner side of the mounting bracket 2 along the sliding path of the movable component 4. Two parallel inner guide rails 3 are symmetrically fixed on the two opposite inner groove walls of the movable groove 6 by countersunk bolts. The inner guide rails 3 are made of wear-resistant steel with chrome plating and the surface roughness is controlled within Ra0.8, which can significantly reduce the frictional resistance during the sliding process. The movable component 4 is assembled from four parts: a movable block 44, a side guide groove 45, a mounting side shaft 42, and a side traveling wheel 41. The two outer side walls of the movable block 44 are directly injection molded with side guide grooves 45 that perfectly match the cross-sectional contour of the inner guide rails 3. The movable block 44 passes through the two sides The side guide groove 45 is directly slidably mounted on the surface of the two inner guide rails 3. On the side end face of the moving block 44 away from the mounting mechanism 5, a horizontally arranged mounting side shaft 42 is rotatably mounted through a bearing seat. A side traveling wheel 41 is fixedly mounted on one end of the mounting side shaft 42. The side traveling wheel 41 is made of silent rubber material. The wheel surface of the side traveling wheel 41 rolls directly against the inner wall of the movable groove 6. When the moving block 44 slides along the inner guide rail 3, the side traveling wheel 41 can roll synchronously on the inner wall of the movable groove 6, forming auxiliary support for the overall movement of the moving block 44. This avoids excessive wear between the side guide groove 45 and the inner guide rail 3 after long-term load operation of the moving block 44, effectively improving the service life of the entire structure.

[0035] As a further optimization of the present invention, a plurality of turbulence fan blades 43 are fixedly installed on the outer cylindrical surface of the mounting side shaft 42, which are evenly distributed along the circumference. The turbulence fan blades 43 are made of thin ABS plastic material, and the blades are inclined at a 30-degree angle to the axis of the mounting side shaft 42. When the mounting side shaft 42 rotates synchronously with the side traveling wheel 41, the turbulence fan blades 43 can synchronously complete the circumferential rotation, continuously generating directional axial airflow. A plurality of arc-shaped air guide grooves 46 extending along the thickness direction of the moving block 44 are integrally formed inside the moving block 44. All arc-shaped air guide grooves 46 are through grooves with both ends completely connected. The air inlet end of the arc-shaped air guide groove 46 faces the arrangement area of ​​the turbulence fan blades 43, and the air outlet end faces the mounting surface of the mounting mechanism 5, ensuring that the airflow generated by the turbulence fan blades 43 can be smoothly directionally conducted through the arc-shaped air guide grooves 46.

[0036] Reference Figure 4As a further optimization of the present invention, the mounting mechanism 5 consists of two parts: a flip motor 51 and a mounting box 52. The flip motor 51 is a micro stepper motor. On the side of the moving block 44 facing the mounting mechanism 5, a motor slot that perfectly matches the shape of the flip motor 51 is opened inward. The flip motor 51 is fixed inside the motor slot by interference fit. Several through air guide holes are opened on the wall of the motor slot. The other end of all the air guide holes is directly connected to the arc-shaped air guide groove 46 inside the moving block 44, ensuring that part of the airflow in the arc-shaped air guide groove 46 can be directly introduced into the motor slot through the air guide holes. The output shaft of the flip motor 51 extends horizontally outward. The mounting box 52 is coaxially fixed to the output end face of the flip motor 51 by a flange. When the flip motor 51 is running, it can directly drive the mounting box 52 to complete any angle rotation from 0 to 360 degrees.

[0037] Reference Figure 4 and Figure 6 As a further optimization of the present invention, the mounting box 52 is integrally injection molded from ABS plastic. The front of the mounting box 52 is provided with a positioning groove 57 for accommodating the mounting shell of the infrared detector. The inner side groove 53 of the positioning groove 57 is provided with mutually perpendicular side grooves 53 and bottom grooves 55. The internal space of the side groove 53 is used to assemble the touch-pressing assembly 54. The touch-pressing assembly 54 consists of two parts: a transverse spring shaft 543 and a touch-pressing post 544. The transverse spring shaft 543 is fixedly installed on the inner bottom surface of the side groove 53 by bolts. A compression spring is fitted on the outside of the transverse spring shaft 543. The center of the touch-pressing post 544 is provided with a through hole that is completely matched with the outer diameter of the transverse spring shaft 543. The touch-pressing post 544 is slidably assembled on the outside of the transverse spring shaft 543 through the through hole. When no external force is applied, the compression spring can push the end of the touch-pressing post 544 out to the outside of the side groove 53.

[0038] As a further optimization of the present invention, two side mounting plates 542 are symmetrically installed on the left and right outer side walls of the pressure post 544 by means of heat fusion fixing. The overall outer contour of the pressure post 544 is completely matched with the inner contour of the side groove 53. The pressure post 544 can complete a stable linear sliding along the extension direction of the side groove 53. The force-bearing end of the pressure post 544 directly passes through the outer side wall of the side groove 53 and extends to the internal space of the positioning groove 57. A cylindrical locking shaft 541 is vertically fixed on the outer side wall of each side mounting plate 542. The locking shaft 541 moves horizontally synchronously with the displacement of the pressure post 544.

[0039] Reference Figure 4 and Figure 7As a further optimization of the present invention, the internal space of the bottom groove 55 is used to assemble the positioning component 56. The positioning component 56 consists of two parts: a longitudinal spring shaft 561 and a positioning post 564. The longitudinal spring shaft 561 is fixedly installed on the inner bottom surface of the bottom groove 55 by bolts. A compression spring is also fitted on the outside of the longitudinal spring shaft 561. The center of the positioning post 564 is provided with a through hole that is completely matched with the outer diameter of the longitudinal spring shaft 561. The positioning post 564 is slidably assembled on the outside of the longitudinal spring shaft 561 through the through hole. Under the limiting action of the locking shaft 541, the positioning post 564 can be stored in the internal space of the bottom groove 55.

[0040] As a further optimization of the present invention, the outer contour of the positioning post 564 matches the inner contour of the bottom groove 55, and the positioning post 564 can complete a stable linear sliding along the extension direction of the bottom groove 55. A cylindrical operating shaft 562 is vertically fixed on the outer side wall of the positioning post 564. A stroke groove extending along the sliding direction of the positioning post 564 is provided on the outer side wall of the mounting box 52. One end of the operating shaft 562 extends directly through the stroke groove to the outside of the mounting box 52. The operator can drive the positioning post 564 by moving the operating shaft 562. After completing the manual reset action, the side of the positioning post 564 is provided with a side locking hole 563 that matches the outer diameter of the locking shaft 541. In the initial state, the end of the locking shaft 541 is directly locked inside the side locking hole 563, locking the position of the positioning post 564. The bottom end of the positioning post 564 is provided with a storage groove 565. Inside the storage groove 565, a positioning insert plate 566 is installed by rotating through a miniature rotating shaft. The positioning insert plate 566 can rotate 90 degrees around the rotating shaft to adapt to the positioning holes of infrared detectors of different specifications.

[0041] The implementation principle of the active infrared detector mounting structure and method of this invention is as follows: The active infrared detector mounting structure uses a U-shaped mounting frame 2 as a rigid support reference. The adjusting motor 1 drives the adjusting screw 7 to drive the moving block 44 with side guide grooves 45 to complete vertical stepless displacement along the inner guide rail 3 on the inner side of the mounting frame 2. The side-mounted wheels 41 on the side of the moving block 44 roll on the inner wall of the movable groove 6 to form lateral auxiliary support to reduce guide rail wear, and simultaneously drive the turbulence fan blades 43 on the mounting side shaft 42 to rotate, generating directional airflow without an additional power source. The flipping motor 51 of the mounting mechanism 5 can drive the mounting box 52 to achieve stepless adjustment of the infrared detector's detection angle. When the detector is pushed into the positioning groove 57 inside the mounting box 52, the detector housing directly contacts the sensor. The pressing post 544 drives the locking shaft 541 to disengage from the side locking hole 563 of the positioning post 564. After the lock is released, the longitudinal spring shaft 561 pops the positioning post 564 out and locks it into the positioning hole of the detector housing. The entire process can be completed quickly without external tools. The airflow generated by the turbulence fan blade 43 is diverted by the arc-shaped air guide groove 46. Part of it blows away the floating dust on the infrared detector detection surface, and the other part is guided into the motor groove through the air guide hole to remove the heat accumulated by the flip motor 51. The rotating positioning insert 566 in the storage groove 565 at the bottom of the positioning post 564 is adapted to the small-sized positioning holes of different specifications of detectors. The detector can be quickly unlocked and disassembled by moving the operating shaft 562 on the outside of the mounting box 52. While flexibly adjusting the height and angle of the detector, the additional effects of self-cleaning and passive heat dissipation are achieved at the same time.

[0042] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
