Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0029] Example:
[0030] like Figure 1 - Figure 6 As shown, this embodiment of the invention provides a smart fall detection device for elderly care, including a bottom shell 1 and a top shell 2. The top shell 2 is fixed to the top of the bottom shell 1. A first annular groove 13 is formed at the top of the side wall of the bottom shell 1, and a first sealing ring 14 is snapped into the first annular groove 13. A PCB board 3 is fixedly installed on the bottom wall of the bottom shell 1, and a control chip 4, a miniature accelerometer 5, a gyroscope sensor 6, and a wireless transmission module 7 are fixedly connected to the surface of the PCB board 3. A battery 8 is fixedly connected to one side of the bottom shell 1, and a notch 9 is formed on the side wall of the bottom shell 1 near the battery 8. A device electrically connected to the battery 8 is fixedly snapped into the notch 9. The charging module 10 has a recessed platform 15 on the side of the notch 9 away from the charging module 10. The bottom of the recessed platform 15 is rotatably connected to a sealing cover 16 via a rotating shaft. The sealing cover 16 has a second annular groove 23 on the side near the inner wall of the recessed platform 15, and a second sealing ring 24 is engaged inside the second annular groove 23. The top of the sealing cover 16 is provided with a locking structure for fixing the sealing cover 16. A boss 27 is fixed in the middle of the upper surface of the top shell 2. A pressure sensor 28 is fixedly connected to the surface of the boss 27. A top cover 29 is slidably sleeved on the surface of the boss 27. Two connecting ropes 33 for wearing around the neck are fixedly connected to both sides of the outer wall of the bottom shell 1.
[0031] like Figure 2 and Figure 3 As shown, a connecting groove 12 is provided on the outer side wall of the top of the bottom shell 1, and an external thread is provided on the surface of the connecting groove 12. A snap-fit part 11 is fixedly connected to the bottom end of the top shell 2, and an internal thread matching the external thread of the connecting groove 12 is provided on the inner wall of the snap-fit part 11. Thus, the top shell 2 can be screwed onto the top of the bottom shell 1 for fixation.
[0032] The portion of the first sealing ring 14 located outside the first annular groove 13 is tightly fitted to the bottom end of the top shell 2, and the portion of the second sealing ring 24 located outside the second annular groove 23 is tightly fitted to the inner wall of the recess 15. When the top shell 2 and the bottom shell 1 are fixedly connected, the first sealing ring 14 provides a seal. When the sealing cover 16 is closed inside the recess 15, the second sealing ring 24 provides a seal. Therefore, the device has better waterproof performance, making it suitable for use by the elderly while bathing.
[0033] like Figures 1-6As shown, the miniature accelerometer 5, gyroscope 6, pressure sensor 28, and wireless transmission module 7 are all electrically connected to the control chip 4. When the miniature accelerometer 5, gyroscope 6, and pressure sensor 28 show data changes, they all transmit information to the control chip 4. The wireless transmission module 7 is equipped with a SIM card, which allows it to dial up to the internet, enabling the control chip 4 to remotely transmit information to the guardian's mobile terminal APP.
[0034] like Figure 2 and Figure 4 As shown, the engaging structure includes a movable groove 18 opened on the top of the sealing cover 16, a first spring 19 fixedly connected to the bottom wall of the movable groove 18, a locking rod 20 fixedly connected to the top of the first spring 19, and a locking groove 17 for engaging the locking rod 20 opened on the top wall of the recess 15.
[0035] When the latch 20 is engaged in the slot 17 by the elastic force of the first spring 19, the sealing cover 16 is fixed inside the recess 15.
[0036] The movable slot 18 has a slot 21 on the side near the outer surface of the bottom shell 1. A lever 22 is fixedly connected to the side of the locking rod 20 near the slot 21. The lever 22 passes through the slot 21 and is slidably connected to the slot 21. When charging is required, the lever 22 can be pushed down to disengage the locking rod 20 from the slot 17.
[0037] A groove 25 is formed at the top of the inner sidewall of the recessed platform 15. A second spring 26 is fixedly connected to the inner sidewall of the groove 25. One end of the second spring 26 located outside the groove 25 contacts the sidewall of the sealing cover 16. When the locking rod 20 disengages from the locking groove 17, the second spring 26 can push the sealing cover 16 open.
[0038] like Figure 2 and Figure 5 As shown, two symmetrical grooves 30 are formed on the outer wall of the boss 27. Slider blocks 31 are fixedly connected to both sides of the inner wall of the top cover 29 near the grooves 30. The sliders 31 are located on the inner wall of the grooves 30 and are slidably connected to them. When the sliders 31 slide within the grooves 30, they can limit the movement of the top cover 29, preventing it from detaching from the boss 27. When an elderly person falls, the top cover 29 is compressed, which in turn compresses the pressure sensor 28, thus obtaining information about the fall.
[0039] like Figure 1 - Figure 6As shown, multiple charging indicator lights 32 are fixedly connected to the outer wall of the bottom shell 1 near the sealing cover 16. The charging port of the charging module 10 faces the sealing cover 16. A power monitoring module 36 is fixedly connected to the surface of the PCB board 3, and the power monitoring module 36 is electrically connected to the control chip 4 and the battery 8. The power monitoring module 36 can monitor the power of the battery 8 in real time. When charging, all the indicator lights 32 are lit, indicating that charging is complete.
[0040] like Figure 1 As shown, the ends of the two connecting ropes 33 furthest from the base shell 1 are respectively fixedly connected to threaded connectors 34 and internal threaded connectors 35. The two connecting ropes 33 are fixedly connected by screwing the internal threaded connector 35 onto the threaded connector 34. Since the connecting ropes 33 are attached to connecting rings on the surface of the base shell 1, their length can be adjusted during actual wear, ensuring the device fits snugly against the skin without significant swaying. Furthermore, since the neck's sway is minimal during normal movement, the device is more accurate in detecting falls when worn around the neck.
[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
