[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] As Figure 1 and Figure 4 shown, the present invention provides a technical solution: a ceiling-mounted and embedded two-in-one presence sensor, including a mounting base 1, an upper cover 31 is provided at the upper end of the mounting base 1, and a touch control display screen 3 is embedded at the upper end of the upper cover 31 to facilitate the user to view by touching the screen. Symmetrically fixed to the outer side wall of the mounting base 1 are side frames 11, and a telescopic frame 2 is provided inside the two side frames 11. The ends of the two telescopic frames 2 are provided with a mounting frame 12. The telescopic frame 2 is slidably connected inside the mounting frame 12, and a quick-release structure for convenient disassembly is provided at the end of the telescopic frame 2.

[0026] As Figure 4 shown, the quick-release structure includes limit frames 23 that are symmetrically slidably connected. The inner top end of the telescopic frame 2 is slidably connected with a cover plate 21. The lower bottom end of the cover plate 21 is fixedly connected with a connecting rod 22. Fixed brackets 24 are fixedly connected to the outer side wall of the limit frame 23 and the outer wall of the connecting rod 22. A link rod 25 is rotatably connected to the inner side walls of the two fixed brackets 24. Through the action of the link rod 25, when in use, only by pulling the connecting rod 22 can the limit frame 23 be driven to separate from the limit groove 111. A magnetic attraction plate 26 for adsorbing the connecting rod 22 is fixedly connected to the inner bottom end of the telescopic frame 2. A sealing ring 27 is embedded at the inner top end of the telescopic frame 2 so as to increase the friction between the cover plate 21 and the telescopic frame 2 and avoid the situation of falling off. A top groove 28 is opened at the upper top end of the cover plate 21, and an easy-pull ring 281 for facilitating the lifting of the cover plate 21 is rotatably connected to the inner bottom end of the top groove 28.

[0027] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the inner bottom end of the mounting base 1 is embedded with a housing 4. The inner bottom end of the housing 4 is fixedly connected with an inner housing 41. The inside of the inner housing 41 is fixedly connected with a backing plate 42. The inner top end of the upper cover 31 is provided with a clamping groove 311. The inner top end of the housing 4 is fixedly connected with a plurality of clamping frames 43 that form a clamping connection with the clamping groove 311 in a circular array, so as to be able to quickly separate or install the housing 4 and the upper cover 31. The lower bottom end of the backing plate 42 is fixedly connected with a millimeter-wave radar 35. The access end of the millimeter-wave radar 35 is fixedly connected with a radar probe 36 for detecting the human body, and the radar probe 36 extends to the outer wall of the mounting base 1. The upper top end of the backing plate 42 is fixedly connected with a single-chip microcomputer 32. The upper top end of the backing plate 42 is fixedly connected with a microwave sensor 33 on one side of the single-chip microcomputer 32. A radar receiving head 37 for receiving radar signals is arranged on the upper top end of the backing plate 42 on one side of the microwave sensor 33. The upper top end of the backing plate 42 is fixedly connected with a storage battery 34 to provide power support for the electronic components on the backing plate 42. The access end of the storage battery 34 is provided with a power connection end 341. The outer side wall of the mounting base 1 is provided with a power connection port 13 corresponding to the power connection end 341.

[0028] Working principle: During use, the mounting base 1 is fixed at a suitable position through the mounting frame 12 as required, and an external wire is inserted into the power connection port 13 and connected to the power connection end 341, so that external power can supply power to the device. The storage battery 34 can ensure that it can also be used in the event of a power outage. When there is a human body in the sensing position, the millimeter-wave radar 35 can sense the human body, transmit the data to the single-chip microcomputer 32, and display the data on the touch display screen 3 through the single-chip microcomputer 32. However, after long-term use, the internal electronic structure of the mounting base 1 will be correspondingly damaged. At this time, it needs to be replaced or its appearance needs to be cleaned. In order not to affect the normal use of the touch display screen 3, the mounting base 1 needs to be disassembled. The user can drive the covering plate 21 to move upward by rotating the easy-pull ring 281. While the covering plate 21 is moving upward, it will pull the connecting rod 22 and the fixed bracket 24 to move upward. And under the action of the connecting rod 25, the limit frame 23 will be pulled to move. Since the limit frame 23 slides inside the telescopic frame 2, the limit frame 23 can only move in a straight line. At this time, the limit frame 23 is separated from the inside of the limit groove 111, and the user can pull out the telescopic frame 2 from the inside of the side frame 11. When installing a new telescopic frame 2, similarly, move the covering plate 21 downward. Under the extrusion of the pressure, the two limit frames 23 will be reset under the drive of the fixed bracket 24 and the connecting rod 25. And when the connecting rod 22 contacts the magnetic attraction plate 26, the connecting rod 22 can be adsorbed to avoid movement, and the friction can be further increased through the sealing ring 27.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
