Description

Technical Field

[0001] The present application relates to the technical field of human activity detectors, and specifically discloses a human activity detector. Background Art

[0002] Human activity detectors are also called human presence sensors. Currently, most human presence sensors use infrared pyroelectric sensors, which divide the space into multiple small areas. When heat energy such as the human body passes through these areas, a signal will be fed back, and then the signal will be sensed to make the corresponding device work.

[0003] However, this infrared human body sensor has obvious disadvantages. Due to the commonality of infrared sensing, it mainly relies on thermal imaging to perceive objects, and the resolution is also low. Once there are too many infrared sources in the environment, the device is prone to misjudgment. In addition to heat sources, including light sources, radio frequency radiation, thermal airflow, etc., will interfere with infrared sensors;

[0004] At the same time, the infrared radiation of the human body is easily blocked. Once there is an obstruction near the infrared human presence sensor, its sensitivity will be greatly affected. In addition, if the current ambient temperature is close to the human body temperature, it will also cause a decrease in detection and sensitivity. If a person is stationary for a long time within the range, it will also fail due to less infrared radiation;

[0005] Therefore, in summary, the layout position of the human activity detector is very important. The connecting base of the traditional human activity detector is usually connected by bolts. Once the layout position is determined, it can be installed directly. However, once the layout position is poor, it is troublesome to disassemble and rearrange it. In view of this, the inventor proposes a human activity detector. Utility Model Content

[0006] The utility model aims to solve the problem that the traditional human activity detector is troublesome to disassemble and rearrange.

[0007] In order to achieve the above object, the utility model provides the following basic solutions:

[0008] The human activity detector comprises a connecting seat, an annular groove opened on the side wall of the connecting seat, an annular ring arranged on the outer periphery of the connecting seat, a penetrating circular groove opened on the side wall of the annular ring, a sliding block sliding between the annular ring and the connecting seat, a telescopic rod arranged at one end of the sliding block away from the connecting seat, a ball hinge assembly fixedly connected to the free end of the telescopic rod, and a human activity detector body connected to the ball hinge assembly.

[0009] The principles and effects of this basic solution are:

[0010] 1. Compared with the prior art, the present device has a simple structure and an ingenious design. The present device mainly makes significant improvements in installation. The sensitivity problem of traditional human activity detectors caused by small problems in the installation position can be solved by the present device. The present device can achieve fine-tuning of the installation position of the human activity detector, thereby directly solving the tediousness of disassembling and reinstalling the traditional human activity detector.

[0011] 2. Compared with the prior art, this device has a huge market, considering that the large-scale location of the installation of the human activity detector will not change. Based on the installation logic of the human activity detector, the human activity detector will be installed at the location closest to the detection location, but this location is a relatively large range and is easily affected by other factors such as the environment. At this time, the use of this device does not require disassembly and reinstallation, which is simpler and more convenient.

[0012] 3. Compared with the prior art, the core of this device lies in the fine-tuning of the installation position of the human activity detector, which can avoid the influence of the external environment on the human activity detector and thus ensure the sensitivity of the human activity detector.

[0013] 4. Compared with the prior art, the present device is provided with a base to realize the circumference adjustment of the human activity detector, a telescopic rod to realize the height adjustment, and a ball hinge assembly to realize the angle fine-tuning. Through the above-mentioned fine-tuning and the combination of fine-tuning, the overall position of the human activity detector is fine-tuned, thereby solving the problem that the traditional human activity detector is troublesome to disassemble and rearrange.

[0014] Furthermore, a mounting hole is formed on the connection seat, and a fixing screw is threadedly connected to the mounting hole.

[0015] Furthermore, sliding rods are provided at both ends of the sliding block, and threaded holes are horizontally opened on the sliding rods. One sliding rod slides in the penetrating circular groove, and the other sliding rod slides in the annular groove.

[0016] Furthermore, it also includes a locking screw used in conjunction with the threaded hole. The locking screw is screwed into one end of the threaded hole, passes through the other end of the threaded hole, and then abuts against the annular groove.

[0017] Furthermore, the ball hinge assembly includes an extension rod coaxially connected to the free end of the telescopic rod, a hinge ball arranged on the extension rod, and a mounting box. The human activity detector body is installed on the mounting box. The mounting box has a ball hinge groove, and the ball hinge groove is hinged to the hinge ball.

[0018] Furthermore, the extension rod is made of metal, the groove wall of the ball hinge groove is made of magnetic material, and the groove wall of the ball hinge groove can be magnetically connected to the extension rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] The figure marks in the drawings of the specification include: connecting seat 1, fixing screw 2, annular ring 3, through circular groove 4, sliding block 5, locking screw 6, annular groove 7, installation box 8, ball hinge groove 9, human activity detector body 10, telescopic rod 11, locking piece 12.

[0024] Implementation example Figure 1 and Figure 2 As shown:

[0025] The human activity detector comprises a connecting seat 1, an annular groove 7 opened on the side wall of the connecting seat 1, an annular ring 3 arranged on the outer periphery of the connecting seat 1, a penetrating circular groove 4 opened on the side wall of the annular ring 3, a sliding block 5 sliding between the annular ring 3 and the connecting seat 1, a telescopic rod 11 arranged at one end of the sliding block 5 away from the connecting seat 1, a ball hinge assembly fixedly connected to the free end of the telescopic rod 11, and a human activity detector body 10 connected to the ball hinge assembly.

[0026] Specifically: a mounting hole is opened on the connection base 1, and a fixing screw 2 is connected to the inner thread of the mounting hole. The connection base 1 needs to be installed near the position to be detected, and fixed by the fixing screw 2, such as Figure 1 As shown, both ends of the sliding block 5 are provided with sliding rods, and threaded holes are horizontally opened on the sliding rods. One of the sliding rods slides in the through circular groove 4, and the other sliding rod slides in the annular groove 7.

[0027] In order to limit the position of the sliding block 5, a locking screw 6 is provided for use with the threaded hole. The locking screw 6 is screwed into the left end of the threaded hole, passes through the right end of the threaded hole, and abuts against the annular groove 7, thereby preventing the sliding block 5 from sliding.

[0028] The ball hinge assembly includes an extension rod coaxially connected to the free end of the telescopic rod 11, a hinge ball arranged on the extension rod and a mounting box 8. The human activity detector body 10 is installed on the mounting box 8. The mounting box 8 is provided with a ball hinge groove 9, and the ball hinge groove 9 is hinged with the hinge ball. The extension rod is made of metal, and the groove wall of the ball hinge groove 9 is made of magnetic material. The groove wall of the ball hinge groove 9 can be magnetically connected to the extension rod.

[0029] Specific implementation process:

[0030] The first step is about the installation of the device. In this case, taking the detection of human activities through a door as an example, the installation position of the device needs to be close to the door, that is, the approximate installation position of the device is determined.

[0031] In the second step, the approximate installation position of the device is not the optimal installation position, because the human activity detector body 10 is too obviously affected by the outside world and usually needs to be adjusted, that is, the human activity detector body 10 is adjusted to the optimal solution of the local position within the approximate range. At this time, frequent installation and disassembly are required.

[0032] In the third step, the device does not need to be repeatedly installed and disassembled frequently. The sliding block 5 is used to achieve fine-tuning of the horizontal position of the human activity detector body 10. The telescopic rod 11 is used, and a locking piece 12 is provided on the telescopic rod 11 to fix the length of the telescopic rod 11. The telescopic rod 11 is used to achieve fine-tuning of the height position of the human activity detector body 10. The ball hinge assembly is used to achieve fine-tuning of the angular position of the ball hinge assembly. The above-mentioned various fine-tunings work together to avoid the troubles caused by frequent installation and disassembly, and then find the optimal solution for the local position of the human activity detector body 10 within the approximate range, and finally determine the final installation position of the human activity detector body 10.

[0033] The device solves the problem that traditional human activity detectors are troublesome to disassemble and rearrange.
