[0002] With the fast pace of modern life, prolonged sitting at work and looking down have become the norm, leading to increasingly common muscle strain problems such as stiff neck and lower back pain. As a result, people have an increasingly urgent need for neck and lower back massage therapy equipment, and home and commercial massage therapy chairs are gradually becoming important tools for relieving muscle fatigue and improving posture.

[0003] Many neck and lumbar massage chairs use a fixed structural design. Although some products have simple backrest or leg rest adjustment functions, they generally suffer from a "one-size-fits-all" experience. They cannot achieve precise adaptation and adaptive massage therapy based on the different body shapes, sitting habits, and actual strain conditions of the neck and waist of different users. The backrest height and neck pillow position of traditional massage chairs are mostly fixed settings, or can only be roughly adjusted manually. It is difficult to accurately fit the neck curve and waist contour of users of different heights and body shapes. This causes the massage points to be misaligned and cannot effectively act on the sore areas of the neck and waist. This not only affects the massage therapy effect, but may also cause discomfort during the massage due to insufficient fit, and may even aggravate muscle strain. Summary of the Invention

A control key 11 is provided on the side wall of the installation box 3. The control key 11 is electrically connected to the adjustable backrest cushion 9. The control key 11 includes an on / off switch, a height adjustment switch, and a height adjustment switch. The height adjustment switch is used to raise the height of the adjustable backrest cushion 9, and the height adjustment switch is used to lower the height of the adjustable backrest cushion 9.

[0023] The working principle of the above technical solution is as follows: the backrest assembly is based on two brackets 1 as the supporting structure, the mounting box 3 fixed between the brackets 1 is the core control and installation carrier, the protective plate 23 protects the mounting box 3 and the internal structure, and the switch 4 on its side wall is used to control the power start and stop of the entire device; multiple protective columns 5 set on the side wall of the mounting box 3 further enhance the connection stability between the mounting box 3 and the protective plate 23 and avoid structural deformation under stress.

[0024] The core adjustment function of the backrest assembly is achieved through the adjustable backrest cushion 9. The fixed backrest cushion 10 serves as the basic support, and together with the adjustable backrest cushion 9, they form a complete backrest support structure. The top of the adjustable backrest cushion 9 is fixedly equipped with a backrest pillow 7 and a neck pillow 8. The neck pillow 8 is located below the backrest pillow 7, which respectively provide auxiliary support for the human neck and head, improving the comfort of use.

[0025] The height adjustment of the adjustable backrest cushion 9 is achieved by the control key 11 on the side wall of the mounting box 3. The control key 11 is electrically connected to the adjustable backrest cushion 9 and includes three function buttons: a power button, a height adjustment button, and a height adjustment button. When the height adjustment button is pressed, the control key 11 sends a height adjustment signal to the adjustable backrest cushion 9, driving its internal structural action to raise the height of the backrest cushion. When the height adjustment button is pressed, a height adjustment signal is sent to lower the height of the backrest cushion. The power button is used to control the start and stop of the adjustable backrest cushion 9 independently, ensuring precise and controllable adjustment operation.

[0026] In another implementation scheme, such as Figures 1-6 As shown, the leg support assembly includes a base plate 14. Two mounting frames 13 are symmetrically fixedly installed on the top of the base plate 14. The two mounting frames 13 are connected to the telescopic assembly. A fixed box 16 is fixedly installed between the two mounting frames 13. A leg pad 17 is fixedly installed on the top of the fixed box 16. Each of the four corners of the bottom of the base plate 14 is provided with a movable wheel 15, one of which is a self-locking movable wheel. Each side wall of the two mounting frames 13 is provided with an arc-shaped plate 19. The other end of the two arc-shaped plates 19 is respectively engaged with an electric push rod 24 and a limiting cylinder 20. Each side wall of the two mounting frames 13 is fixedly connected with a limiting block 18. The two limiting blocks 18 are located inside the arc-shaped plate 19. The other end of the two limiting blocks 18 is respectively engaged with an electric push rod 24 and a limiting cylinder 20.

[0027] The leg support assembly uses the base plate 14 as its load-bearing foundation. Two symmetrically fixed mounting frames 13 on the top of the base plate 14 serve as both the support structure for the leg support and key components for transmission connection with the telescopic assembly. The fixed box 16 between the two mounting frames 13 has a leg pad 17 on its top to support the user's legs and improve leg comfort.

[0028] The four corners of the base plate 14 have movable wheels 15, which enable the flexible movement of the entire device. One of the self-locking wheels can be locked after the device moves to a designated position to prevent accidental slippage and ensure stability during use. The side walls of the two mounting frames 13 are provided with arc-shaped plates 19 and limiting blocks 18. The limiting blocks 18 are located inside the arc-shaped plates 19. The two work together to engage with the electric push rod 24 and the limiting cylinder 20 respectively, which can fix and limit the movement, ensuring that the electric push rod 24 and the limiting cylinder 20 are firmly connected to the leg support assembly and preventing loosening or displacement during transmission.

[0029] In another implementation scheme, such as Figures 1-6As shown, the telescopic assembly includes two connecting columns 21. One end of each connecting column 21 is fixedly connected to a corresponding mounting frame 13. Multiple limiting plates 22 are provided on the outer walls of both connecting columns 21. An electric push rod 24 is fixedly connected to the other end of one of the connecting columns 21. The other side of the electric push rod 24 is connected to the side wall of the mounting box 3. A limiting cylinder 20 is fixedly connected to the side wall of the mounting box 3. The limiting cylinder 20 is slidably connected to one end of the other connecting column 21.

[0030] The telescopic component, as the core component connecting the backrest component and the leg support component, is responsible for adjusting the distance between the two to adapt to the sitting posture needs of different users. It mainly consists of two connecting columns 21, multiple limiting plates 22, electric push rods 24 and limiting cylinders 20.

[0031] One end of each of the two connecting posts 21 is fixedly connected to the two mounting frames 13 of the leg support assembly, respectively, to achieve a rigid connection between the telescopic assembly and the leg support assembly; the other end of one of the connecting posts 21 is fixedly connected to the electric push rod 24, and the other side of the electric push rod 24 is connected to the side wall of the mounting box 3 of the backrest assembly, serving as the power source for the telescopic movement; one end of the other connecting post 21 is slidably connected to the limiting cylinder 20 fixed to the side wall of the mounting box 3, serving as a guide and limiting function to ensure that the telescopic process is smooth and does not deviate.

[0032] When it is necessary to adjust the distance between the backrest and the leg rest, the electric push rod 24 is activated. When the electric push rod 24 extends, it pushes the connecting column 21 connected to it to move, thereby moving the entire leg rest assembly away from the backrest assembly. When the electric push rod 24 retracts, it pulls the connecting column 21 back, moving the leg rest assembly closer to the backrest assembly. Multiple limiting plates 22 provided on the outer wall of the connecting column 21 can limit the extension and retraction stroke of the connecting column 21, avoid excessive extension and retraction that could damage the components, and ensure the safety and reliability of the extension and retraction action.

[0033] Working principle: The backrest assembly is based on two brackets 1 as the supporting structure. The mounting box 3 fixed between the brackets 1 is the core control and installation carrier. The protective plate 23 protects the mounting box 3 and its internal structure. The switch 4 on its side wall is used to control the power start and stop of the entire device. Multiple protective columns 5 set on the side wall of the mounting box 3 further enhance the connection stability between the mounting box 3 and the protective plate 23 and prevent the structure from deforming under stress.

[0034] The core adjustment function of the backrest assembly is achieved through the adjustable backrest cushion 9. The fixed backrest cushion 10 serves as the basic support, and together with the adjustable backrest cushion 9, they form a complete backrest support structure. The top of the adjustable backrest cushion 9 is fixedly equipped with a backrest pillow 7 and a neck pillow 8. The neck pillow 8 is located below the backrest pillow 7, which respectively provide auxiliary support for the human neck and head, improving the comfort of use.

[0035] The height adjustment of the adjustable backrest cushion 9 is achieved by the control key 11 on the side wall of the mounting box 3. The control key 11 is electrically connected to the adjustable backrest cushion 9 and includes three function buttons: a power button, a height adjustment button, and a height adjustment button. When the height adjustment button is pressed, the control key 11 sends a height adjustment signal to the adjustable backrest cushion 9, driving its internal structure to perform an action to raise the height of the backrest cushion. When the height adjustment button is pressed, a height adjustment signal is sent to lower the height of the backrest cushion. The power button is used to control the start and stop of the adjustable backrest cushion 9 independently, ensuring precise and controllable adjustment operation. The leg support assembly uses the base plate 14 as its load-bearing foundation. Two symmetrically fixed mounting frames 13 on the top of the base plate 14 serve as both the support structure for the leg support and key components for transmission connection with the telescopic assembly. The fixed box 16 between the two mounting frames 13 has a leg pad 17 on its top to support the user's legs and improve leg comfort.

[0036] The four corners of the base plate 14 have movable wheels 15, which enable the flexible movement of the entire device. One of the self-locking movable wheels can be locked after the device moves to a designated position to prevent the device from sliding accidentally and to ensure the stability of use. The side walls of the two mounting frames 13 are provided with arc-shaped plates 19 and limiting blocks 18. The limiting blocks 18 are located inside the arc-shaped plates 19. The two work together to engage with the electric push rod 24 and the limiting cylinder 20 respectively, which play a role in fixing and limiting, ensuring that the electric push rod 24 and the limiting cylinder 20 are firmly connected to the leg support assembly and avoiding loosening or displacement during the transmission process. The telescopic component, as the core component connecting the backrest component and the leg support component, is responsible for adjusting the distance between the two to adapt to the sitting posture needs of different users. It mainly consists of two connecting columns 21, multiple limiting plates 22, electric push rods 24 and limiting cylinders 20.

[0037] One end of each of the two connecting posts 21 is fixedly connected to the two mounting frames 13 of the leg support assembly, respectively, to achieve a rigid connection between the telescopic assembly and the leg support assembly; the other end of one of the connecting posts 21 is fixedly connected to the electric push rod 24, and the other side of the electric push rod 24 is connected to the side wall of the mounting box 3 of the backrest assembly, serving as the power source for the telescopic movement; one end of the other connecting post 21 is slidably connected to the limiting cylinder 20 fixed to the side wall of the mounting box 3, serving as a guide and limiting function to ensure that the telescopic process is smooth and does not deviate. In use, the device is powered on via the switch 4 on the side wall of the protective plate 23. Depending on individual needs, the height of the adjustable backrest cushion 9 is adjusted using the control key 11 on the side wall of the mounting box 3, ensuring the pillow 7, neck pillow 8, and backrest cushion fit snugly against the head, neck, and back. The distance between the leg rest assembly and the backrest assembly is adjusted by controlling the extension and retraction of the electric push rod 24, allowing the legs to rest comfortably on the leg pad 17. When moving the device, the casters 15 at the bottom of the base plate 14 are used to push the device to the designated position. Locking the self-locking casters completes the setup and use of the entire device. The components work together to achieve adjustable backrest height, adjustable leg rest distance, and overall mobility and stability, meeting the personalized needs of different users.
