Description

Technical Field

[0001] This invention relates to the field of travel assistance technology, and in particular to an intelligent emergency alarm device for preventing elderly people from falling. Background Technology

[0002] As the population ages, the issues of mobility assistance and travel safety for the elderly are receiving increasing attention. As an important mobility aid for the elderly, the functional design of wheelchairs directly affects their travel safety and convenience.

[0003] Existing wheelchairs for the elderly generally have limited functionality, possessing only basic mobility functions and lacking dedicated fall detection and emergency call alarm structures. As a result, it is difficult for the elderly to quickly attract the attention of those around them and receive assistance after a fall. Some wheelchairs with lighting functions have fixed installation positions for their lighting components, making it impossible to adjust the lighting angle and height according to the usage scenario. They also lack intelligent control mechanisms that sense light, resulting in poor lighting practicality in dim environments and easy light interference in bright environments. Meanwhile, existing equipment lacks a dedicated display platform for elderly people's personal information and emergency rescue information, and the information display is not linked to the fall triggering mechanism. After an elderly person falls, those around them cannot obtain key rescue information such as their identity and medical history in a timely manner. In addition, the sensors, lighting and alarm components that come with wheelchairs are mostly fixed. The monitoring range of the sensors cannot be flexibly adjusted, making it difficult to adapt to different usage environments. Furthermore, when the related components are rotated for adjustment, they are prone to direct contact with the wheelchair body, causing collision damage. When the wheelchair is parked against a wall, it is also prone to bumping into things due to the blind spot of the rear wheels, further reducing the safety and lifespan of the equipment. Summary of the Invention

[0004] The main objective of this invention is to provide an intelligent emergency alarm device for preventing falls in the elderly. This device can effectively solve the problems of traditional elderly wheelchairs, such as limited functionality, lack of a dedicated fall prevention emergency alarm structure, fixed positions of lighting and sensing components that cannot be intelligently adjusted, delayed delivery of rescue information after a fall, easy bumping and knocking when the wheelchair is parked, easy contact between the wheelchair and the main body when adjusting the components, and inflexible sensor monitoring range that cannot be adapted to the usage scenario.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A smart emergency alarm device for preventing falls in the elderly includes a wheelchair, two multi-functional emergency audible and visual alarm lights capable of illumination and alarm, two adjustment mechanisms, two armrest assemblies respectively disposed on both sides of the wheelchair, a moving mechanism, a transparent window, an operation screen, and an information display showing user information. The two adjustment mechanisms are used to adjust the illumination position of the two multi-functional emergency audible and visual alarm lights according to the usage status of the wheelchair, and lock them to the wheelchair after adjustment. The armrest assembly includes armrests, and the transparent window and the operation screen are detachably installed inside the two armrests. The moving mechanism cooperates with one of the armrest assemblies to move the information display to directly below the transparent window and clean the dust from the outer surface of the transparent window. The adjustment mechanism adjusts the working status of the multi-functional emergency audible and visual alarm lights according to the light intensity in the direction of wheelchair movement.

[0006] Preferably, the armrest assembly further includes a support arm fixedly connected to the wheelchair and a connecting plate fixedly connected to the support arm and the armrest. The support arm and the connecting plate are respectively provided with a sliding groove and a storage groove, and a guide groove that communicates with each other is provided between the storage groove and the sliding groove.

[0007] Preferably, the moving mechanism includes a mounting base fixedly connected to the information display, a fixed seat fixedly installed inside the sliding groove, a motor fixedly installed at one end of the fixed seat, a slider fixedly connected to the mounting base and slidingly engaged with the guide groove, a screw threadedly connected to the slider, and a rotating shaft fixedly connected to the screw and the motor.

[0008] Preferably, the moving mechanism further includes a slide rod fixedly connected to the mounting base and slidably engaged with the connecting plate, and an L-shaped plate fixedly connected to one end of the slide rod and slidably engaged with the top of the handle, wherein the contact surface between the L-shaped plate and the handle is provided with a cleaning brush.

[0009] Preferably, the adjustment mechanism includes a mounting bracket for mounting the multifunctional emergency audible and visual alarm light and having a threaded cylinder fixedly mounted at one end; a light sensor detachably mounted in a slot on one side of the mounting bracket and a protective plate for protecting the light sensor; a rotating shaft rotatably connected to the wheelchair; a support frame fixedly sleeved on the outer wall of the rotating shaft and having a motor fixedly mounted at one end; a screw rod rotatably connected to the rotating shaft and fixedly connected to the output end of the motor rod; and a guide plate fixedly mounted at one end of the mounting bracket and slidably inserted into the support frame. The threaded cylinder is threadedly sleeved on the screw rod, and a lampshade is detachably mounted on the top of the mounting bracket.

[0010] Preferably, the second motor, the light sensor, the multi-functional emergency audible and visual alarm light, the operation screen, the information display, and the first motor are all wirelessly connected via a wireless module.

[0011] Preferably, the adjustment mechanism further includes a magnetic suction plate fixedly installed on the outer wall of the rotating shaft and used for magnetic connection with the wheelchair. When the support frame rotates outward by 180 degrees, the two ends of the support frame are rubbed and locked with the reinforcing rod inside the wheelchair, and after the support frame rotates, the multi-functional emergency sound and light alarm light is positioned near the rear wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention integrates a multi-functional emergency audible and visual alarm light, a light sensor, and an adjustment mechanism. A second motor drives a second screw to move the mounting bracket horizontally along the support frame. This not only precisely adjusts the horizontal position of the multi-functional emergency audible and visual alarm light but also simultaneously adjusts the horizontal position of the light sensor. This allows for flexible adjustment of the ambient light monitoring range of the light sensor, enabling accurate detection of light in different areas along the wheelchair's movement direction. Furthermore, the light sensor and the multi-functional emergency audible and visual alarm light are wirelessly linked, intelligently adjusting the alarm light's illumination and standby status based on the monitored light intensity. This allows the device to adapt to different lighting environments. Before the support frame rotates outward, the second motor can move the mounting bracket to its furthest point from the wheelchair, effectively preventing direct contact and collision between the mounting bracket, alarm light, and the wheelchair body, thus reducing the equipment damage rate.

[0013] 2. This invention achieves the linkage between adjusting the position of the information display and cleaning the dust on the transparent window by setting a moving mechanism inside the wheelchair armrest assembly. A motor drives a screw to move a slider, quickly pushing the information display directly below the transparent window. Furthermore, the fall detection module is wirelessly linked with the moving mechanism and alarm light. When an elderly person falls, the information display simultaneously shows rescue information and the alarm light sounds and flashes, allowing nearby people to promptly obtain crucial rescue information and detect the fall. After resetting, the information display can be stored in the armrest assembly's storage slot, providing dust and impact protection and significantly improving the efficiency of emergency rescue after a fall.

[0014] 3. This invention features a dual adjustment mechanism that combines angle and position adjustment. Supported by a rotating shaft, the support frame can rotate 180 degrees. Combined with the magnetic locking between the magnetic plate and the wheelchair, and the friction locking between the support frame and the wheelchair reinforcement rod, the multi-functional emergency audible and visual alarm light can be adjusted to the rear wheel position, providing illumination guidance for parking the wheelchair against a wall and effectively preventing rear wheel collisions due to blind spots. Furthermore, the sliding of the mounting bracket on the support frame, combined with the angle rotation of the support frame, allows for multi-dimensional adjustment of the multi-functional emergency audible and visual alarm light's illumination position, ensuring precise coverage of different areas for wheelchair movement and parking, further enhancing the device's adaptability.

[0015] 4. This invention establishes a signal connection between all electrical components via a wireless module, enabling intelligent linkage control of Motor 1, Motor 2, light sensor, alarm light, information display, and operation screen. The elderly can perform operations such as information display, lighting position adjustment, and alarm mode triggering with one click on the operation screen. The operation logic is simple and adapted to the usage habits of the elderly. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-7As shown, an intelligent emergency alarm device for preventing falls in the elderly includes a wheelchair 1, two multi-functional emergency audible and visual alarm lights 6 capable of illumination and alarm, two adjustment mechanisms 4, two armrest assemblies 2 respectively disposed on both sides of the wheelchair 1, a moving mechanism 3, a transparent window 5, an operation screen 7, and an information display 305 displaying user information. The two adjustment mechanisms 4 are used to adjust the illumination position of the two multi-functional emergency audible and visual alarm lights 6 according to the usage status of the wheelchair 1, and lock with the wheelchair 1 after adjustment. The armrest assembly 2 includes armrests 203, and the transparent window 5 and operation screen 7 are detachably installed inside the two armrests 203. The moving mechanism 3 cooperates with one of the armrest assemblies 2 to move the information display 305 directly below the transparent window 5 and clean the dust on the outer surface of the transparent window 5. The adjustment mechanism 4 adjusts the working status of the multi-functional emergency audible and visual alarm lights 6 according to the light intensity in the direction of movement of the wheelchair 1.

[0020] In this embodiment, the multi-functional emergency sound and light alarm light 6, adjustment mechanism 4, moving mechanism 3, information display 305, and other functional components are integrated with the wheelchair 1 body. The adjustment mechanism 4 enables flexible adjustment and locking of the lighting position of the multi-functional emergency sound and light alarm light 6. The moving mechanism 3 coordinates the position adjustment of the information display 305 with the cleaning of the transparent window 5. Simultaneously, the light sensor 409 intelligently controls the working state of the multi-functional emergency sound and light alarm light 6 based on the ambient light intensity. Furthermore, the information display 305 is designated as a dedicated information display for the elderly and associated with a fall trigger mechanism. Additionally, a multi-functional emergency alarm light 6 is specifically designed. The rear-wheel steering structure of the emergency audible and visual alarm light 6 is adapted to the scenario where the wheelchair 1 is parked against a wall. This design allows the wheelchair 1 to have multiple functions, including lighting, display of elderly information, emergency alarm, cleaning of the transparent window 5, and anti-collision parking. The detachable installation design of the transparent window 5 and the control panel 7 also improves the convenience of equipment maintenance. It effectively solves the problems of traditional wheelchairs having single functions, lacking a dedicated anti-fall alarm device, and being easily damaged by collisions when parked against a wall. It realizes safety protection for the elderly in all scenarios of wheelchair travel, greatly improving the safety and practicality of use. The control panel 7 has a built-in communication module. When the device falls, it can call the emergency contact person through the Bluetooth module and the communication module to promptly remind family members.

[0021] like Figure 1-5As shown, in one embodiment, the armrest assembly 2 further includes a support arm 201 fixedly connected to the wheelchair 1 and a connecting plate 202 fixedly connected to the support arm 201 and the armrest 203. The support arm 201 and the connecting plate 202 are respectively provided with a sliding groove 2011 and a storage groove 2021. A guide groove 2012 communicating with the storage groove 2021 and the sliding groove 2011 is provided between them. The moving mechanism 3 includes a mounting base fixedly connected to the information display 305, a fixing seat 300 fixedly installed inside the sliding groove 2011, and a fixing seat... The moving mechanism 3 includes a motor 301 fixedly mounted at one end, a slider 304 fixedly connected to the mounting base and slidably engaged with the guide groove 2012, a screw 303 threadedly connected to the slider 304, and a rotating shaft 302 fixedly connected to the screw 303 and the motor 301. The moving mechanism 3 also includes a slide rod 306 fixedly connected to the mounting base and slidably engaged with the connecting plate 202, and an L-shaped plate 307 fixedly connected at one end of the slide rod 306 and slidably engaged with the top of the handle 203. The contact surface between the L-shaped plate 307 and the handle 203 is provided with a cleaning brush.

[0022] In this embodiment, the support arm 201, the connecting plate 202, and the handle 203 form an integrated handle assembly 2. A sliding groove 2011, a guide groove 2012, and a storage groove 2021 are interconnected within the support arm 201 and the connecting plate 202 to provide a stable motion guide trajectory and a protective storage space for components for the moving mechanism 3. The motor 301 drives the rotating shaft 302 to rotate the screw 303. The screw 303, through its threaded engagement with the slider 304, pushes the slider 304 to slide along the guide groove 2012, achieving precise linear movement of the information display 305. Simultaneously, the mounting base synchronously drives the sliding rod 306 to slide along the connecting plate 202, causing the L-shaped plate 307 to slide along the top of the handle 203. The cleaning brush on its contact surface cleans the dust from the outer surface of the transparent window 5. A fall-triggered linkage mechanism is also set; when the device detects a fall, the motor 301 automatically starts to push the information display 305. The dual sliding guide cooperation between slider 304 and guide groove 2012, and slider 306 and connecting plate 202, effectively avoids deviation and jamming during the movement of information display 305, ensuring the stability of the mechanism's operation. Storage groove 2021 can also protect the information display 305 from dust and impact after it is reset. It realizes the linkage operation of adjusting the position of information display 305 and cleaning transparent window 5. Two functions are completed with one drive, simplifying the operation logic. When a fall occurs, the elderly person's information can be quickly displayed below transparent window 5 to help people around them obtain rescue information in a timely manner.

[0023] like Figure 6-7As shown, in one embodiment, the adjustment mechanism 4 includes a mounting bracket 406 for mounting a multi-functional emergency audible and visual alarm light 6 and having a threaded cylinder 405 fixedly mounted at one end; a light sensor 409 detachably mounted in a slot on one side of the mounting bracket 406 and a protective plate 408 for protecting the light sensor 409; a rotating shaft 401 rotatably connected to the wheelchair 1; a support frame 402 fixedly sleeved on the outer wall of the rotating shaft 401 and having a motor 403 fixedly mounted at one end; a screw 404 rotatably connected to the rotating shaft 401 and fixedly connected to the output end of the motor 403; and a guide plate 407 fixedly mounted at one end of the mounting bracket 406 and slidably inserted into the support frame 402. The threaded cylinder 405 is threadedly sleeved on the screw 404, and a lamp cover 410 is detachably mounted on the top of the mounting bracket 406.

[0024] In this embodiment, the multi-functional emergency sound and light alarm light 6 is fixedly installed by the mounting bracket 406, and a detachable light sensor 409 and a protective plate 408 are integrated on the mounting bracket 406. At the same time, a transmission structure of the bearing bracket 402 and the screw 404 is built with the rotating shaft 401 as support. The screw 404 is driven to rotate by the motor 403. The mounting bracket 406 slides along the bearing bracket 402 through the threaded engagement between the screw 404 and the threaded cylinder 405. The sliding insertion of the guide plate 407 and the bearing bracket 402 provides rigid limit for the mounting bracket 406. A detachable lampshade 410 is also provided on the top of the mounting bracket 406. The transmission between motor 403 and screw 404 enables precise stepless adjustment of the illumination height of the multi-functional emergency audible and visual alarm light 6. The guide plate 407 effectively prevents the mounting bracket 406 from shifting or tipping over during movement. The protective plate 408 prevents the light sensor 409 from being damaged by external collisions or dust contamination. The lampshade 410 provides dustproof and collision-proof protection for the multi-functional emergency audible and visual alarm light 6. Furthermore, the light sensor 409, protective plate 408, and lampshade 410 are all detachable, greatly improving the convenience of component replacement and equipment maintenance. The light sensor 409 can also detect the ambient light intensity in real time, providing accurate data support for the operation status control of the multi-functional emergency audible and visual alarm light 6, and working together with the multi-functional emergency audible and visual alarm light 6 to achieve all-day alarm protection.

[0025] like Figure 1-7As shown, in one embodiment, the adjustment mechanism 4 adjusts the working status of the multi-functional emergency audible and visual alarm light 6 according to the light intensity of the wheelchair 1's direction of movement. The motor 2 403, light sensor 409, multi-functional emergency audible and visual alarm light 6, operation screen 7, information display 305 and motor 1 301 are all wirelessly connected through a wireless module. The adjustment mechanism 4 also includes a magnetic suction plate 400 fixedly installed on the outer wall of the rotating shaft 401 for magnetic connection with the wheelchair 1. When the support frame 402 rotates outward by 180 degrees, the two ends of the support frame 402 are rubbed and locked with the reinforcing rod inside the wheelchair 1, and after the support frame 402 rotates, the multi-functional emergency audible and visual alarm light 6 is positioned near the rear wheel.

[0026] In this embodiment, a wireless module is used to establish a signal connection between the second motor 403, the light sensor 409, the multi-functional emergency sound and light alarm light 6, the operation screen 7, the information display 305 and the first motor 301, so as to realize the intelligent linkage control of each electrical component. At the same time, a magnetic plate 400 is set on the outer wall of the rotating shaft 401 to achieve magnetic locking of the initial position of the support frame 402. A friction locking structure is also designed so that the support frame 402 can rotate outward 180 degrees and then lock with the internal reinforcing rod of the wheelchair 1, so that the multi-functional emergency sound and light alarm light 6 can be moved to the rear wheel position of the wheelchair 1. The magnetic locking of the magnetic plate 400 ensures the stability of the support frame 402 and the multi-functional emergency audible and visual alarm light 6 when the wheelchair 1 moves normally, preventing shaking or displacement. The friction locking after the support frame 402 rotates enables flexible switching of the illumination direction of the multi-functional emergency audible and visual alarm light 6, allowing it to accurately illuminate the rear wheel area of ​​the wheelchair 1. This makes it easier for users to control the distance when parking against the wall and reduces the probability of the wheelchair 1 being bumped or damaged. The light sensor 409 can also adjust the working status of the multi-functional emergency audible and visual alarm light 6 in real time according to the light intensity in the direction of the wheelchair 1's movement, realizing intelligent control of lighting and alarm, making the device adaptable to various usage scenarios such as normal travel and parking against the wall.

[0027] Working principle: This device uses wheelchair 1 as a carrier. All electrical components establish real-time signal linkage through a wireless module. It has a built-in fall detection module and forms a linkage triggering mechanism with motor 301 and multi-functional emergency sound and light alarm 6. When working, light sensor 409 first detects the light intensity in the direction of wheelchair 1's movement in real time, and then transmits the detection signal to multi-functional emergency sound and light alarm 6 through the wireless module. When the light intensity is lower than the preset value, the lighting function of multi-functional emergency sound and light alarm 6 is automatically triggered. When the light intensity is higher than the preset value, the lighting is turned off and it enters standby mode. The light sensor 409 and multi-functional emergency sound and light alarm 6 maintain real-time linkage. When an abnormal environment or fall detection signal is detected, the sound and light alarm mode of multi-functional emergency sound and light alarm 6 will be triggered immediately. In daily life, the elderly can manually issue information display commands through the operation screen 7. After the wireless module receives the command, it triggers the motor 301 to start. The motor 301 drives the rotating shaft 302 to rotate the screw 303, pushing the slider 304 to slide along the guide groove 2012 and moving the information display 305 from the storage groove 2021 to directly below the transparent window 5. The mounting base simultaneously drives the slide rod 306 to slide along the connecting plate 202, so that the L-shaped plate 307 slides along the top of the handle 203 and cleans the dust on the outer surface of the transparent window 5 with the cleaning brush. The elderly can switch the content displayed on the information display 305 through the operation screen 7. After the display is completed, the motor 301 is started in reverse to drive the information display 305 back into the storage groove 2021. When the fall detection module detects that an elderly person has fallen, it will simultaneously activate motor 301 and multi-functional emergency sound and light alarm 6 via the wireless module. Motor 301 will quickly push the information display 305 to the bottom of the transparent window 5 to display the elderly person's key rescue information. At the same time, the multi-functional emergency sound and light alarm 6 will activate the sound and light alarm mode to attract the attention of those around. When adjusting the horizontal position of the multi-functional emergency audible and visual alarm light 6, a command is issued through the operation panel 7, triggering the wireless module to start the second motor 403. The second motor 403 drives the second screw 404 to rotate. Through the threaded engagement between the second screw 404 and the threaded cylinder 405, the mounting bracket 406 slides along the support frame 402. After adjusting to the target position, the second motor 403 stops and the mounting bracket 406 is locked in position through thread self-locking. When the wheelchair 1 needs to be parked against the wall, the support frame 402 is manually rotated outward 180 degrees, the magnetic suction plate 400 is released from magnetic locking, and the two ends of the support frame 402 form a friction lock with the internal reinforcing rod of the wheelchair 1, so that the multi-functional emergency audible and visual alarm light 6 moves to the rear wheel position of the wheelchair 1 and controls the distance to the wall through the illumination of the rear wheel area. After parking, the support frame 402 is rotated in the opposite direction to reset and lock through the magnetic suction plate 400.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
