Abstract
Description
Technical Field
[0001] This utility model relates to the field of human body sensing devices, specifically millimeter-wave radar human body sensing devices. Background Technology
[0002] As people pay increasing attention to environmental pollution, reducing carbon emissions and achieving energy conservation and environmental protection are urgent priorities. Therefore, monitoring the presence of people in work areas such as offices, meeting rooms, and production workshops to determine whether electrical equipment such as air conditioners and lights need to be turned off has led to the development of many detection methods. Traditional methods are based on the infrared principle. The main idea is that the human body has a constant body temperature and therefore emits infrared rays of a specific wavelength of about 10μm. Infrared probes work by detecting the infrared rays of about 10μm emitted by the human body. The infrared rays of about 10μm emitted by the human body are enhanced by Fresnel filters and focused onto the infrared sensing source. The infrared sensing source usually uses pyroelectric elements. When these elements receive infrared radiation from the human body and their temperature changes, they lose their charge balance and release charges. After subsequent detection and processing by the circuit, an alarm signal is generated.
[0003] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the existing technology: During use, damage to the pins inside the connector of traditional millimeter-wave radar human body detection devices requires replacement of the entire connector, increasing the cost and difficulty of maintenance. Therefore, a new technical solution is needed to address these issues. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a millimeter-wave radar human body detection device to solve the technical problem that the current millimeter-wave radar human body detection device requires the replacement of the entire connector when the pins inside the connector are damaged, which increases the maintenance cost of the millimeter-wave radar human body detection device.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a millimeter-wave radar human body sensing device is designed, including a mounting plate, on which a device housing is fixedly connected. A connector is fixedly connected to one end of the device housing. A circuit board is connected to one end of the connector via a metal pin. A splicing groove is provided at the other end of the metal pin. An extension pin is connected to one end of the splicing groove via a threaded groove. A threaded section is provided on the outside of the extension pin. A conductive sheet is fixedly connected to the other end of the extension pin. A contact plate is connected to the inside of the splicing groove via a spring.
[0006] Preferably, the top of the connector is sealed with a cover plate by bolts.
[0007] Preferably, one end of the metal pin is soldered to the circuit board, and the other end of the metal pin is fixedly connected to the inside of the connector.
[0008] Preferably, the threaded section of the extended pin is connected inside the threaded groove.
[0009] Preferably, the other end of the conductive sheet abuts against the other end of the contact sheet.
[0010] Preferably, one end of the spring is fixedly connected to the inner wall of the splicing groove, and the other end of the spring is fixedly connected to one end of the contact plate. The size of the contact plate matches the size of the splicing groove and is slidably connected to its inner wall.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention combines a splicing groove, a threaded groove, an extension pin, a threaded segment, a conductive sheet, a spring, and a contacting sheet. When a pin inside a millimeter-wave radar human body sensing device is damaged and needs to be replaced, the cover plate is first removed from the connector, the damaged extension pin is then unscrewed from the splicing groove, and a new extension pin is installed into the splicing groove. This avoids the need to replace the entire connector when a pin inside the connector is damaged, saving costs and reducing the difficulty of repairing millimeter-wave radar human body sensing devices.
[0013] When the new extension pin is installed inside the splicing slot, the conductive sheet will exert a squeezing force on the contact sheet. During this process, the spring will exert a rebound force on the contact sheet, so that the contact sheet is firmly pressed against the conductive sheet, thereby preventing poor contact between the conductive sheet and the contact sheet.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] Example 1: Millimeter-wave radar human body detection device, see [link / reference] Figures 1 to 5 The device includes a mounting plate 1, on which a device housing 11 is fixedly connected. A connector 12 is fixedly connected to one end of the device housing 11. One end of the connector 12 is connected to a circuit board 14 via a metal pin 13. The other end of the metal pin 13 has a splicing groove 15. One end of the splicing groove 15 is connected to an extension pin 17 via a threaded groove 16. The extension pin 17 has a threaded section 18 on its exterior, which connects to the inside of the threaded groove 16. One end of the metal pin 13 is soldered to the circuit board 14, and the other end of the metal pin 13 is fixedly connected to the connector 14. Inside the head 12, the top of the connector 12 is sealed with a cover plate 22 by bolts. When the pins inside the millimeter-wave radar human body detection device are damaged and need to be replaced, the cover plate 22 is first removed from the connector 12, the damaged extension pin 17 is then unscrewed from the splicing groove 15, and the new extension pin 17 is then installed into the splicing groove 15. This avoids the phenomenon of replacing the entire connector 12 when the pins inside the connector 12 are damaged, saving the cost of repairing the millimeter-wave radar human body detection device and reducing the difficulty of repairing the millimeter-wave radar human body detection device.
[0022] The other end of the extension pin 17 is fixedly connected to a conductive sheet 19. The inside of the splicing groove 15 is connected to a contact piece 21 via a spring 20. The other end of the conductive sheet 19 abuts against the other end of the contact piece 21. One end of the spring 20 is fixedly connected to the inner wall of the splicing groove 15, and the other end of the spring 20 is fixedly connected to one end of the contact piece 21. The size of the contact piece 21 matches the size of the splicing groove 15 and is slidably connected to its inner wall. When a new extension pin 17 is installed inside the splicing groove 15, the conductive sheet 19 will exert a squeezing force on the contact piece 21. During this process, the spring 20 will generate a rebound force on the contact piece 21, so that the contact piece 21 is firmly pressed against the conductive sheet 19, thereby preventing poor contact between the conductive sheet 19 and the contact piece 21.
