Detailed Implementation

[0027] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Reference Figure 1-8 This utility model provides an indoor fall detection radar installation structure, including a junction box top cover 10 with an opening at the bottom. Inside the junction box top cover 10, from top to bottom, there are a PCB board 20, a junction box bottom cover 30, and a mounting plate 40. A detachable fall detection radar 50 is provided below the mounting plate 40. The PCB board 20 is sealed in the junction box top cover 10 by the junction box bottom cover 30, and the mounting plate 40 is fixed to the lower surface of the junction box bottom cover 30. During assembly, the junction box top cover 10 is first installed on the indoor ceiling, and then the fall detection radar 50 is snapped onto the bottom of the mounting plate 40.

[0029] The mounting plate 40 has locking buckles 42 evenly distributed along the edge of its lower surface. The fall detection radar 50 has a boss structure, and the top edge of the fall detection radar 50 has locking slots 51 evenly distributed to cooperate with the locking buckles 42. During assembly, the top cover 10 of the junction box is first installed on the ceiling of the room, and then the fall detection radar 50 can be snapped into place under the mounting plate 40 by cooperating with the locking buckles 42 and the locking slots 51, which facilitates the assembly and disassembly of the fall detection radar 50.

[0030] Among them, the fall detection radar 50 is a millimeter-wave radar, a radar system that uses electromagnetic waves in the millimeter-wave frequency band for detection and sensing. It obtains information such as the target's distance, speed, and angle by emitting millimeter-wave signals and receiving the echo signals reflected from the target. In fall detection, the application of millimeter-wave radar is mainly based on the following principles:

[0031] When a person falls, their posture and movement change significantly, and these changes alter the echo signals received by millimeter-wave radar. By monitoring these signal changes, millimeter-wave radar can detect the occurrence of a fall.

[0032] Millimeter-wave radar has strong penetrating power and can detect the human body through obstacles such as clothing and thin walls, so it is not limited by factors such as ambient light and privacy protection.

[0033] Millimeter-wave radar has strong anti-jamming capabilities and can accurately identify human targets in complex environments, reducing the possibility of misjudgment and missed detection.

[0034] The top cover 10 of the junction box has two symmetrical positioning posts 11 on both sides. The PCB board 20 has positioning grooves 21 on both sides that cooperate with the positioning posts 11. The positioning grooves 21 and the positioning posts 11 cooperate to place the PCB board 20 into the top cover 10 of the junction box and limit the position of the PCB board 20 to prevent the PCB board 20 from rotating in the top cover 10 of the junction box.

[0035] The PCB board 20 has a power supply 22 and a controller 23 on its lower surface. The controller 23 is electrically connected to the power supply 22 and the fall detection radar 50 respectively. The power supply 22 supplies power to the controller 23 and the fall detection radar 50.

[0036] Furthermore, an electrical connector is provided in the wiring between the fall detection radar 50 and the controller 23, so that the connected wiring can be disconnected when the fall detection radar 50 is disassembled.

[0037] The lower cover 30 of the junction box fits into the opening at the bottom of the top cover 10 of the junction box, and the PCB board 20 is sealed in the top cover 10 of the junction box through the lower cover 30.

[0038] The lower cover 30 of the junction box has an insertion hole 31 on its surface corresponding to the position of the positioning post 11, and the mounting plate 40 has a positioning hole 41 on its surface corresponding to the position of the positioning post 11. A threaded hole is provided at the center of the end of the positioning post 11, and a positioning bolt is installed in the threaded hole. The mounting plate 40 and the lower cover 30 of the junction box are fixed to the end of the positioning post 11 by the positioning bolt and the threaded hole. The PCB board 20 is sealed inside the top cover 10 of the junction box by the lower cover 30. During assembly, the PCB board 20 is first placed into the junction box by the positioning groove 21 and the positioning post 11. Inside the top cover 10, align the insertion hole 31 on the bottom cover 30 with the positioning post 11, and place the mounting plate 40 on the bottom cover 30, aligning the positioning hole 41 on the mounting plate 40 with the insertion hole 31. Then, pass the positioning bolt through the positioning block 41 and the insertion hole 31 in sequence, and then insert the end of the positioning bolt into the threaded hole at the end of the positioning post 11 and tighten the positioning bolt to fix the mounting plate 40 and the bottom cover 30 on the positioning post 11. The PCB board 20 is then sealed in the top cover 10 of the box through the bottom cover 30.

[0039] The mounting plate 40 has a disc-shaped structure. The locking buckles 42 on the lower surface of the mounting plate 40 are located on the same ring. The locking buckles 42 correspond to the locking slots 51. The fall detection radar 50 is engaged with the mounting plate 40 by the engagement of the locking buckles 42 and the locking slots 51. The locking buckles 42 and the locking slots 51 are interference-fitted. During assembly, the top cover 10 of the junction box is first installed on the indoor ceiling. Then, the fall detection radar 50 can be engaged with the mounting plate 40 by the engagement of the locking buckles 42 and the locking slots 51, which facilitates the assembly and disassembly of the fall detection radar 50.

[0040] The working principle of this utility model is as follows: First, the PCB board 20 is placed into the top cover 10 of the junction box by cooperating with the positioning groove 21 and the positioning post 11. Then, the insertion hole 31 on the bottom cover 30 of the junction box is aligned with the positioning post 11. At the same time, the mounting plate 40 is placed on the bottom cover 30 of the junction box, so that the positioning hole 41 on the mounting plate 40 is aligned with the insertion hole 31. Then, the positioning bolt passes through the positioning block 41 and the insertion hole 31 in sequence. Then, the end of the positioning bolt is inserted into the threaded hole at the end of the positioning post 11 and the positioning bolt is tightened to fix the mounting plate 40 and the bottom cover 30 of the junction box on the positioning post 11. The PCB board 20 is sealed in the top cover 10 of the junction box by the bottom cover 30 of the junction box. Then, the top cover 10 of the junction box is installed on the ceiling of the room. Then, the fall detection radar 50 can be snapped into the bottom of the mounting plate 40 by cooperating with the locking buckle 42 and the locking slot 51, which facilitates the assembly and disassembly of the fall detection radar 50.
