Description

Technical Field

[0001] This utility model relates to a human fall detection device based on millimeter-wave radar, belonging to the field of monitoring equipment technology. Background Technology

[0002] As people age, various physiological functions decline significantly, making the elderly more prone to falls and serious injuries. The main function of fall detection devices is to monitor and identify fall events in real time, and trigger an alarm upon detection to promptly notify relevant personnel to handle the situation, thereby reducing the likelihood of injury.

[0003] Some existing fall detection devices need to be installed on the ceiling of the house. Because the device is installed at a high position, it needs to be disassembled and reassembled every time it is charged. Users often need to use a ladder for installation. However, if a family member bumps into the ladder or the user accidentally steps into a hole, the installer is easily injured, making the operation somewhat dangerous. To address these issues, we provide a fall detection device based on millimeter-wave radar. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a human fall detection device based on millimeter-wave radar. The specific technical solution is as follows:

[0005] A human fall detection device based on millimeter-wave radar includes a mounting base. A threaded rod is connected to the bottom surface of the mounting base. A detector is threadedly connected to the outer surface of the threaded rod. A storage shell is connected to the outer surface of the detector. Multiple telescopic plates are installed inside the storage shell. A counterweight push plate is slidably connected to the outer surface of the storage shell. A transmission plate is connected to the bottom surface of the counterweight push plate. A barrier plate is slidably connected to the inside of the transmission plate. A positioning block one is rotatably connected to the inside of the transmission plate. A spring is connected to the outer surface of the positioning block one. A positioning block two is rotatably connected to the inside of the barrier plate.

[0006] Preferably, the upper surface of the detector is in contact with the bottom surface of the mounting base, and the bottom end of the multiple telescopic plate is slidably connected to the upper surface of the barrier plate.

[0007] Preferably, the storage shell has a sliding groove inside, and a limiting plate is slidably connected to the inner side wall of the sliding groove. The outer surface of the limiting plate is connected to the outer surface of the transmission plate.

[0008] Preferably, a crossbar is connected inside the transmission plate, and the outer surface of the crossbar is rotatably connected to the inside of the barrier plate.

[0009] Preferably, a telescopic rod is installed on the outer surface of the first positioning block, and the output end of the telescopic rod is connected to the upper surface of the second positioning block.

[0010] Preferably, the end of the spring away from the first positioning block is connected to the upper surface of the second positioning block, and the spring is sleeved on the outer surface of the telescopic rod.

[0011] Preferably, the outer surface of the transmission plate is slidably connected to the outer surface of the storage shell, the outer surface of the barrier plate is slidably connected to the interior of the detector, and a placement groove is provided inside the transmission plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This human fall detection device based on millimeter-wave radar works by coordinating multiple telescopic plates and a counterweight push plate. The counterweight push plate is movable, providing downward thrust to the transmission plate. The transmission plate, carrying a blocking plate, moves downwards, allowing a spring to pull the blocking plate to a position blocking the output end of the multiple telescopic plates. After the user pushes the multiple telescopic plates into the housing with a long object, the blocking plate blocks them. The multiple telescopic plates can extend and retract, and after they extend, the user can rotate the detector by moving the two telescopic plates. This allows the detector to be installed on or removed from the threaded rod without the need for a ladder, making it very convenient and solving the problem of the danger of installing and removing the detector using a ladder.

[0014] 2. This human fall detection device based on millimeter-wave radar works by cooperating with components such as positioning block one, positioning block two, and telescopic rod. Positioning block one and positioning block two can rotate, and this rotation prevents the telescopic rod from obstructing the movement between the transmission plate and the barrier plate. The telescopic rod can limit the orientation of the spring when it is compressed, so that the spring will not bulge too much to one side when compressed, thus avoiding the springs from getting tangled together. It is very practical. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 - Figure 5 The device includes a mounting base 1, a threaded rod 2 connected to the bottom surface of the mounting base 1, a detector 3 threadedly connected to the outer surface of the threaded rod 2, and a hole opened inside the mounting base 1. The user can pass a bolt through the hole to fix the mounting base 1 to the ceiling of the room. The mounting base 1 will restrict the position of the threaded rod 2. The user can fix the detector 3 to the threaded rod 2 by rotating it.

[0023] The outer surface of the detector 3 is connected to the housing 4. Multiple telescopic plates 5 are installed inside the housing 4. The detector 3 will fix the position of the housing 4. The outer surface of the multiple telescopic plates 5 is provided with a plate. The housing 4 can restrict the position of the plate to prevent the multiple telescopic plates 5 from being completely pulled out from the housing 4.

[0024] A counterweight push plate 6 is slidably connected to the outer surface of the storage shell 4. A transmission plate 7 is connected to the bottom surface of the counterweight push plate 6. The counterweight push plate 6 is relatively heavy and will fix the position of the transmission plate 7. The weight of the counterweight push plate 6 itself can easily push the transmission plate 7 to move.

[0025] The transmission plate 7 has a sliding connection to a baffle plate 8 inside, and a rotatable connection to a positioning block 9 inside. The baffle plate 8 restricts the position of the transmission plate 7, preventing it from moving laterally. The transmission plate 7 has a rod inside, and the positioning block 9 can rotate around the rod inside the transmission plate 7.

[0026] A spring 10 is connected to the outer surface of the positioning block 9, and a positioning block 11 is rotatably connected inside the baffle plate 8. The positioning block 9 restricts the position of the spring 10. The baffle plate 8 has a rod inside, and the positioning block 11 can rotate around the rod inside the baffle plate 8.

[0027] The upper surface of the detector 3 contacts the bottom surface of the mounting base 1, and the bottom end of the multi-telescopic plate 5 is slidably connected to the upper surface of the barrier plate 8. The mounting base 1 restricts the position where the detector 3 can move upward. When the barrier plate 8 is inserted into the detector 3, the barrier plate 8 will block the output end of the multi-telescopic plate 5, preventing the multi-telescopic plate 5 from extending.

[0028] The storage shell 4 has a sliding groove 12 inside. The inner side wall of the sliding groove 12 is slidably connected to a limiting plate 13. The outer surface of the limiting plate 13 is connected to the outer surface of the transmission plate 7. The inner side wall of the sliding groove 12 is relatively smooth, so the friction force experienced by other items when moving on the inner side wall of the sliding groove 12 is small. The sliding groove 12 will restrict the position that the limiting plate 13 can move. By restricting the position that the limiting plate 13 can move, the position that the transmission plate 7 can move is restricted, so that the transmission plate 7 will not completely detach from the storage shell 4.

[0029] The transmission plate 7 is internally connected to a crossbar 14. The outer surface of the crossbar 14 is slidably connected to the inside of the barrier plate 8. The transmission plate 7 fixes the position of the crossbar 14 so that the crossbar 14 cannot move. The crossbar 14 can provide support for the barrier plate 8, allowing the barrier plate 8 to rotate around the crossbar 14.

[0030] A telescopic rod 15 is installed on the outer surface of positioning block 19. The output end of the telescopic rod 15 is connected to the upper surface of positioning block 21. Positioning block 19 will fix the position of the telescopic rod 15. When the angle between the barrier plate 8 and the transmission plate 7 changes, positioning block 19 and positioning block 21 will rotate to change the orientation of the telescopic rod 15 so that the telescopic rod 15 will not affect the change of the angle between the transmission plate 7 and the barrier plate 8.

[0031] The end of spring 10 away from positioning block 19 is connected to the upper surface of positioning block 21. Spring 10 is sleeved on the outer surface of telescopic rod 15. Spring 10 will provide tension to positioning block 21. Positioning block 21 moves with the blocking plate 8, so that the transmission plate 7 and the blocking plate 8 form a 90-degree angle, so that the blocking plate 8 blocks the multiple telescopic plates 5.

[0032] The outer surface of the transmission plate 7 is slidably connected to the outer surface of the storage shell 4, and the outer surface of the barrier plate 8 is slidably connected to the interior of the detector 3. The transmission plate 7 has a placement groove 16 inside. After the user pushes the counterweight push plate 6 upward a little, the spring 10 can pull the barrier plate 8 into the detector 3. Then the user stops pushing the counterweight push plate 6 and moves the transmission plate 7 to the lowest movable position, so that the bottom surface of the barrier plate 8 can contact the mounting base 1, so that the barrier plate 8 will not be pushed away by the multiple telescopic plates 5. The barrier plate 8 has the same placement groove 16 inside. The two placement grooves 16 are used to accommodate the positioning block 9, the spring 10, the positioning block 11, and part of the telescopic rod 15. The storage shell 4 also has a groove inside, and the other part of the positioning block 9, the spring 10, the positioning block 11, and the telescopic rod 15 can move in the groove of the storage shell 4.

[0033] The detector 3, the multiple telescopic plate 5, and the telescopic rod 15 in this application are common devices in the prior art, and this application will not elaborate on their models or internal structures.

[0034] When using this invention, to remove the detector 3, the user can use two long sticks to push the counterweight push plate 6 on one side upwards. The movement of the counterweight push plate 6 causes the transmission plate 7 to move along with the blocking plate 8. As the blocking plate 8 moves, it slowly detaches from the surface of the multiple telescopic plates 5. Then, the multiple telescopic plates 5 extend under gravity. After both multiple telescopic plates 5 have extended, the user can grasp both multiple telescopic plates 5 and move them to rotate the detector 3. This rotation causes the detector 3 to detach from the threaded rod 2. The user can then charge the detector 3. During installation, the user can... Pull out the multiple telescopic plate 5 and place the stick behind it to support the plate and prevent it from retracting. Then, the user can attach the detector 3 to the threaded rod 2 and move the multiple telescopic plate 5 to install the detector 3 on the rod 2. The user can then use the stick to push the multiple telescopic plate 5 back into the housing 4. At the same time, the counterweight push plate 6 will keep the transmission plate 7 at the bottom. After the multiple telescopic plate 5 moves into the housing 4, the spring 10 will pull the positioning block 11 to block the barrier plate 8. The user can then use another stick to push the multiple telescopic plate 5 upwards, giving the barrier plate 8 space to insert into the detector 3, thus completing the installation.
