Description

Technical Field

[0001] This utility model relates to the technical field of anti-fall waist protection devices, specifically to a wearable anti-fall waist protection device for the elderly. Background Technology

[0002] A fall protection lumbar support device is a protective device used to protect the waist and reduce the risk of falls. It is usually composed of components such as a lumbar support plate, straps, sensors, and cushioning structures (such as airbags). It provides support and protection for the waist during daily activities, sports, or accidental imbalance by actively monitoring human posture or passively cushioning impact forces. Wearable fall protection lumbar support devices for the elderly integrate sensor technology, intelligent algorithms, and inflatable protection, and have functions such as real-time monitoring, active warning, and rapid inflation cushioning. It is an important intelligent protective equipment to help the elderly live safely and prevent accidental injuries.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Most wearable anti-fall and lumbar support devices for the elderly are usually made with Velcro. However, the hook and loop sides of the Velcro will gradually wear down after repeated sticking and tearing. In addition, the hook side of the Velcro will attract hair and soft fabrics such as wool, which will reduce the adhesion and cause it to fall off when worn. This affects the stability and reduces safety. Utility Model Content

[0005] The purpose of this invention is to provide a wearable anti-fall and waist support device for the elderly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wearable anti-fall waist support device for the elderly, including a waist support plate, a first waist support belt fixedly connected to one side of the waist support plate, a second waist support belt fixedly connected to the other side of the waist support plate, a limit component fixedly connected to one side of the first waist support belt, and limit teeth evenly fixedly connected to the outside of the second waist support belt.

[0007] The lower inner surface of the lumbar support plate is provided with a miniature air tank. An air inlet pipe is installed on the top of the miniature air tank through a solenoid valve. An air bladder is installed on one side of the air inlet pipe. The inner side of the lumbar support plate is provided with a controller, a gyroscope sensor and an acceleration sensor.

[0008] The limiting component includes a frame fixedly connected to one end of the first waist support belt. A pull rod is slidably connected to one end of the frame. One end of the pull rod passes horizontally through the inside of the spring and is fixedly connected to a sliding block. Connecting blocks are fixedly connected to the top and bottom of the sliding block. A limiting block is fixedly connected to one end of the sliding block.

[0009] The beneficial effects of this utility model are as follows: Through the limiting component, the limiting block can enter the inner side of the limiting tooth through the elastic deformation of the spring, thereby realizing the limiting work of the second waist support belt. This allows the wearer to wear the belt effectively and flexibly adjust the tightening length of the second waist support belt according to their own comfort, increasing convenience. At the same time, it has good stability after the limiting is completed, thus effectively preventing the belt from falling off during wear, thereby increasing stability and improving safety during wear.

[0010] To achieve effective restraint of the second lumbar support belt:

[0011] As a further improvement to the above technical solution: the spring and the sliding block form an elastic structure, and the upper and lower inner surfaces of the frame are provided with limiting grooves that are consistent with the external dimensions of the connecting block.

[0012] The beneficial effects of this improvement are as follows: Through the above-mentioned settings, the limiting block can enter the inner side of the limiting tooth through the elastic deformation of the spring, thereby limiting the second waist support belt accordingly. When the spring undergoes elastic deformation, the connecting block will slide inside the limiting groove, thus ensuring the limiting and stability of the sliding block during movement, preventing it from falling off, ensuring the stability after wearing, and flexibly adjusting the tightening length of the second waist support belt according to the wearer's comfort, effectively avoiding the situation of being too tight or too loose when wearing, and increasing the comfort during use.

[0013] To provide some protection for the wearer in the event of a fall:

[0014] As a further improvement to the above technical solution: the gyroscope sensor, accelerometer sensor and solenoid valve are connected in series.

[0015] The beneficial effects of this improvement are as follows: With the above settings, when the gyroscope sensor detects a large change in the angle of the human body and the accelerometer sensor detects a large change in the speed of the human body, it will transmit an electrical signal to the controller. The controller will then open the solenoid valve, thereby inflating the airbag. This allows the wearer to be protected by the airbag when falling, reducing the possibility of injury.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0023] Please see Figures 1 to 4 A wearable anti-fall waist support device for the elderly includes a waist support plate 1, a first waist support belt 2 fixedly connected to one side of the waist support plate 1, a second waist support belt 3 fixedly connected to the other side of the waist support plate 1, a limit component 4 fixedly connected to one side of the first waist support belt 2, and limit teeth 5 evenly fixedly connected to the outside of the second waist support belt 3.

[0024] The lower inner surface of the lumbar support plate 1 is provided with a miniature air tank 6. The top of the miniature air tank 6 is equipped with an air inlet pipe 8 through a solenoid valve 7. An airbag 9 is installed on one side of the air inlet pipe 8. The inner side of the lumbar support plate 1 is provided with a controller 10, a gyroscope sensor 11 and an acceleration sensor 12.

[0025] The limiting component 4 includes a frame 401 fixedly connected to one end of the first waist support belt 2. A pull rod 402 is slidably connected to one end of the frame 401. One end of the pull rod 402 passes horizontally through the inside of the spring 403 and is fixedly connected to the sliding block 404. Connecting blocks 405 are fixedly connected to the top and bottom of the sliding block 404. A limiting block 406 is fixedly connected to one end of the sliding block 404.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the spring 403 and the sliding block 404 form an elastic structure, and the upper and lower inner surfaces of the frame 401 are provided with limiting grooves that are consistent with the external dimensions of the connecting block 405.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the gyroscope sensor 11, the accelerometer sensor 12, and the solenoid valve 7 are connected in series.

[0028] The wearable anti-fall and lumbar support device for the elderly works as follows:

[0029] First, place the lumbar support plate 1 on your waist. Then, pull the lever 402. The spring 403 will contract, causing the sliding block 404 to move horizontally under the limiting action of the connecting block 405 and the limiting groove. At this time, the connecting block 405 will slide inside the limiting groove. Then, insert the second lumbar support belt 3 into the inside of the frame 401. When the tightness is appropriate, release the lever 402. The spring 403 will extend, causing the sliding block 404 to move horizontally under the limiting action of the connecting block 405 and the limiting groove. This allows the limiting block 406 to enter the inside of the limiting tooth 5, thereby limiting the second lumbar support belt 3. In the initial stage, the wearer completes the wearing process. The gyroscope sensor 11 (model: ICM-20602) collects the tilt angle value of the human body, and the accelerometer sensor 12 (model: ADXL345) collects the instantaneous acceleration value. The data is transmitted to the controller 10 (model: STC89C52) via wireless signal. Based on the preset value of the controller 10, the solenoid valve 7 (model: JQF1018) is opened, allowing the gas inside the miniature gas tank 6 (model: KSD00005) to enter the airbag 9 through the air inlet pipe 8, thereby inflating the airbag 9 and protecting the wearer.
