Description

Technical Field

[0001] This utility model relates to the field of health and wellness technology, and in particular to a home fall detector. Background Technology

[0002] With the aging population, home-based elderly care safety is receiving increasing attention, especially for seniors living alone, as falls have become a significant threat to their health and even lives. Bedrooms and bathrooms are key areas where seniors frequently engage in daily activities and are prone to falls. In bedrooms, seniors may lose their balance due to weakness or slippery floors when getting up or out of bed. Bathrooms, with their damp floors, limited space, and lack of handrails, present a significantly higher risk of falls than other areas.

[0003] However, traditional fall detection solutions have significant limitations: while camera monitoring can directly capture fall behavior, cameras raise privacy concerns, and their installation in private spaces like bedrooms and bathrooms easily raises user concerns about privacy breaches, making them difficult to widely accept. Existing radar-based fall detection devices often have fixed-installation radar modules, limiting the flexibility of the monitoring angle. Because radar signals propagate in a certain direction, fixed-angle radar modules struggle to cover the complex layouts of bedrooms and bathrooms (such as areas obstructed by beds or cabinets), resulting in a significantly limited detection range and blind spots. This makes it impossible to comprehensively capture the elderly person's activity in different locations within the space, potentially missing the optimal time for fall warning and failing to effectively ensure the elderly person's home safety. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a home fall detector.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a household fall detector, including a base, a ball seat, a radar module and a cable; A spherical cavity is provided on the base; The ball seat is rotatably mounted inside the ball cavity and has a detection window at its front end; The radar module is housed inside the spherical mount and positioned opposite the detection window. One end of the cable is inserted into the ball mount and connected to the radar module, while the other end extends out of the base and is connected to an external power source. The ball mount can rotate within the ball cavity to change the angle of the radar module.

[0006] As one of the preferred embodiments of this utility model, the base includes a first base body and a second base body. The second base body is installed at the rear end of the first base body through a first detachable structure and forms a spherical cavity between the second base body and the first base body.

[0007] As one of the preferred embodiments of this utility model, a friction sleeve that abuts against the ball seat is provided inside the ball cavity.

[0008] As one of the preferred embodiments of this utility model, the first detachable structure is configured as a first threaded connection structure.

[0009] As one of the preferred embodiments of this utility model, the ball seat includes a first ball, a second ball, and a protective cover; The detection window is formed on the first sphere; The second sphere is mounted on the rear end of the first sphere through a second detachable structure, and a cavity is formed between the second sphere and the first sphere; The protective cover is installed at the detection window; The radar module is housed within the cavity.

[0010] As one of the preferred embodiments of this utility model, the rear side of the radar module abuts against the second sphere, and the protective cover is provided with a plurality of support rods that abut against the front side of the radar module, so that the radar module is confined between the protective cover and the second sphere and there is a gap between the radar module and the protective cover.

[0011] As one of the preferred embodiments of this utility model, the second detachable structure is configured as a second threaded connection structure.

[0012] As one of the preferred embodiments of this utility model, the base is provided with a mounting groove, and a magnetic component is provided in the mounting groove for magnetic connection to the mounting position.

[0013] As one of the preferred embodiments of this utility model, a recessed support platform is provided on the periphery of the rear end of the base, and an installation groove is provided on the support platform, which can support the ceiling.

[0014] As one of the preferred embodiments of this utility model, a home fall detector also includes a metal plate adhered to the mounting position, and a magnetic component magnetically connected to the metal plate.

[0015] The beneficial effects of this utility model are as follows: A home fall detector includes a base, a ball seat, a radar module, and a cable. The base has a spherical cavity. The ball seat is rotatably mounted within the cavity and has a detection window at its front end. The radar module is mounted within the ball seat and arranged opposite to the detection window. One end of the cable passes through the ball seat and connects to the radar module, while the other end extends outside the base and is connected to an external power source. The ball seat can rotate within the cavity to change the angle of the radar module. By mounting the radar module within the rotatable ball seat, the ball seat can rotate freely within the cavity of the base, thereby enabling the radar module to achieve multi-directional and multi-angle adjustments. Users can precisely adjust the monitoring angle of the radar module according to the spatial layout of the bedroom and bathroom, the placement of furniture, and the daily activity patterns of the elderly, ensuring that the radar signal covers all key areas within the space. This effectively avoids blind spots caused by obstructions such as beds and cabinets, significantly expanding the detection range and improving the comprehensiveness and accuracy of fall detection. It also resolves the conflict between privacy protection and fall detection. Attached Figure Description

[0021] Reference Figures 1-3 A home fall detector includes a base 10, a ball seat 20, a radar module 30, and a cable 40; A spherical cavity 13 is provided on the base 10; The ball seat 20 is rotatably disposed inside the ball cavity 13 and has a detection window 24 at its front end; The radar module 30 is housed inside the ball mount 20 and is arranged opposite to the detection window 24; One end of the cable 40 is inserted into the ball seat 20 and connected to the radar module 30, while the other end extends to the outside of the base 10 and is connected to an external power source. The ball seat 20 can rotate within the ball cavity 13 to change the angle of the radar module 30.

[0022] Reference Figures 1-3 The base 10 serves as the mounting foundation for the entire monitor and also provides a rotatable mounting space for the ball seat 20. Specifically, the base 10 includes a first seat body 11 and a second seat body 12. The second seat body 12 is mounted on the rear end of the first seat body 11 through a first detachable structure 51 and forms a ball cavity 13 between the second seat body 12 and the first seat body 11. Preferably, the first detachable structure 51 is configured as a first threaded connection structure. The detachable design not only facilitates the installation, disassembly, and maintenance of the ball seat 20, but also ensures the structural stability of the ball cavity 13 through the tightness of the threaded connection, avoiding component loosening during long-term use.

[0023] The ball seat 20 is rotatably embedded in the spherical cavity 13. Its front detection window 24 is arranged opposite to the internal radar module 30, providing a channel for the transmission and reception of radar signals. Since the ball seat 20 and the spherical cavity 13 are spherically fitted together, the ball seat 20 can rotate freely in multiple dimensions around the center of the spherical cavity 13, thereby driving the radar module 30 inside it to adjust its angle synchronously. At the same time, a friction sleeve 60 is provided inside the spherical cavity 13 to abut against the ball seat 20. It can abut tightly against the surface of the ball seat 20. The friction between the friction sleeve 60 and the ball seat 20 is used to achieve positioning after rotation, ensuring that the radar module 30 will not shift due to its own weight or slight external force after being adjusted to the target angle, thus ensuring the stability of the monitoring angle.

[0024] One end of the cable 40 passes through the inside of the ball seat 20 to establish an electrical connection with the radar module 30, and the other end extends to the outside of the base 10 to connect to an external power source, providing a continuous and stable power supply to the radar module 30 and ensuring that the equipment can work continuously for a long time. In addition, the way the cable 40 is laid avoids the rotating parts of the ball seat 20, so it will not affect the angle adjustment operation of the ball seat 20, and also avoids the cable 40 from getting tangled or damaged during rotation.

[0025] Reference Figures 1-3 The ball seat 20 includes a first ball 21, a second ball 22 and a protective cover 23; a detection window 24 is formed on the first ball 21; the second ball 22 is installed at the rear end of the first ball 21 through a second detachable structure 52 and forms a cavity 25 between the second ball 22 and the first ball 21; the protective cover 23 is disposed at the detection window 24; and the radar module 30 is disposed in the cavity 25.

[0026] Specifically, the ball seat 20 consists of a first ball 21, a second ball 22, and a protective cover 23, forming a closed cavity 25 adapted for the installation of the radar module 30. The first ball 21 has an integrally formed detection window 24, which serves as the entry and exit channel for radar signals. The second ball 22 is assembled at the rear end of the first ball 21 through a second detachable structure 52. Preferably, the second detachable structure 52 is set as a second threaded connection structure. After the two are spliced ​​together, the cavity 25 is constructed inside to accommodate the radar module 30. This disassembled design facilitates the installation, maintenance, and replacement of the radar module 30. The threaded connection also ensures the sealing of the cavity 25, reducing the corrosion of the radar module 30 by dust, moisture, etc.

[0027] As the core component of fall detection, the radar module 30 rests against the second sphere 22 at its rear. The protective cover 23 is provided with multiple support rods 70 that rest against the front of the radar module 30. This ensures that the radar module 30 is confined between the protective cover 23 and the second sphere 22, and that there is a gap between the radar module 30 and the protective cover 23. This securely confines the radar module 30 between the protective cover 23 and the second sphere 22. At the same time, the length design of the support rods 70 maintains a reasonable gap between the radar module 30 and the protective cover 23, which not only prevents the protective cover 23 from blocking the radar signal, but also prevents external debris from directly contacting the radar module 30, thus providing protection and extending the service life of the radar module 30.

[0028] Reference Figures 1-3 The base 10 is fixed by a magnetic structure, adapting to the needs of different installation scenarios. Specifically, a recessed support platform 80 is provided on the periphery of the rear end of the base 10, and an installation groove 81 is provided on the base 10. Preferably, the installation groove 81 is provided on the support platform 80, which can support the ceiling. A magnetic element 82 is provided in the installation groove 81 for magnetic connection to the installation position. When the monitor needs to be installed on a metal installation position such as a ceiling, the support platform 80 can directly abut against the surface of the installation position. The magnetic force between the magnetic element 82 and the metal installation position is used to achieve quick fixation. The recessed design of the support platform 80 can ensure that the device fits tightly with the installation position after installation, reducing shaking.

[0029] If the installation location is made of a non-magnetic material (such as a wooden ceiling or wall), a home fall detector also provides a metal plate 90 that is adhered to the installation location. A magnetic component 82 is magnetically connected to the metal plate 90. The metal plate 90 can be fixed to the installation location first by adhesive, and then the device can be installed by using the magnetic connection between the magnetic component 82 and the metal plate 90. This magnetic installation method does not require drilling holes in the installation location or damaging the decoration structure. The installation and disassembly process is simple and convenient, and it is suitable for the installation needs of different decoration environments such as bedrooms and bathrooms. At the same time, the stability of the magnetic connection can ensure that the device will not fall off during long-term use.

[0030] When using, first select the appropriate fixing method according to the installation scenario, and fix the base 10 to the target installation position (such as the bedroom ceiling or the upper part of the bathroom wall) with the magnetic component 82, ensuring that the support platform 80 is tightly attached to the installation position. Then, according to the layout of the monitoring space (such as the position of the bed and cabinet) and the daily activity trajectory of the elderly, manually rotate the ball seat 20: the ball seat 20 rotates along the spherical surface in the ball cavity 13, driving the internal radar module 30 to adjust the angle synchronously until the radar signal emitted by the radar module 30 through the detection window 24 can cover the key activity areas in the space (such as the path to getting out of bed, the bathroom washing area, etc.).

[0031] After adjustment, the friction between the friction sleeve 60 and the ball seat 20 positions the ball seat 20 at the current angle to prevent it from rotating on its own. After connecting to an external power source via the cable 40, the radar module 30 starts working, continuously emitting radar signals and receiving reflected signals through the detection window 24. Utilizing the non-visual perception characteristic of radar technology, it captures the activity status of the human body in space without taking images. When a fall-related action is detected, a subsequent early warning mechanism can be triggered, such as sending an early warning signal to associated devices.

[0032] The advantages of this invention are as follows: By placing the radar module inside a rotatable ball base, the ball base can rotate freely within the spherical cavity of the base, thereby enabling the radar module to be adjusted in multiple directions and angles. Users can precisely adjust the monitoring angle of the radar module according to the spatial layout of the bedroom and bathroom, the placement of furniture, and the daily activity patterns of the elderly, so that the radar signal can cover all key areas in the space, effectively avoiding monitoring blind spots caused by obstructions such as beds and cabinets, significantly expanding the detection range, improving the comprehensiveness and accuracy of fall detection, and also resolving the contradiction between privacy protection and fall detection.

[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
