Description

Technical Field

[0001] This utility model relates to the field of posture correction technology, and in particular to a posture support device. Background Technology

[0002] A posture support device, also known as a posture assistive device or posture corrector, is a type of rehabilitation aid or health care device used to help users maintain a stable sitting posture. It is suitable for people who need to maintain a sitting posture for long periods of time, such as office workers, students, and drivers. At the same time, for people with spinal or cervical spine diseases or injuries, posture supports can also provide certain assistance and rehabilitation effects. They can be used in various scenarios such as home, office, and school. Whether studying, working, or resting, they can provide effective support and correction for users. Poor sitting posture can lead to spinal curvature, deformation, and even spinal-related diseases such as cervical spondylosis and lumbar spondylosis. Posture supports can help maintain the natural curve of the spine, reduce the pressure on the spine, and thus prevent the occurrence of these diseases.

[0003] A search revealed Chinese patent CN220024590U, which discloses a posture corrector. To provide posture reminders, a vibration motor is required in both the seat and back cushions. However, this adds complexity to the already complex internal structure of the cushions, which already require multiple pressure sensors. Furthermore, the vibration motor can cause discomfort and reduce user experience, and the point-like vibration reminders provided by the motor often lack sufficient intensity. Therefore, this patent utilizes the piezoelectric effect of piezoelectric ceramic elements to collect pressure data and uses the inverse piezoelectric effect to provide vibration reminders, thus avoiding the need for a vibration motor. This solves the problems of complex internal structures and discomfort in the seat and back cushions of existing posture correctors. The piezoelectric ceramic element array in this posture corrector, under the excitation of a controller, can achieve surface vibration reminders, providing a stronger reminder intensity compared to existing posture correctors.

[0004] The aforementioned posture corrector improves comfort during use and reduces the feeling of foreign objects. However, existing technologies typically provide posture support in the form of cushions, relying on the support of the buttocks and lower back when sitting. After prolonged use, cushion-type posture correctors, which only provide support for the buttocks and lower back, offer relatively weak support for the upper body. Consequently, fatigue over time can still lead to hunchback. Posture correctors are unable to correct hunchback, thus reducing the quality of posture support and correction. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As attached Figure 1-6 As shown, one embodiment of this utility model is a sitting posture support device, including a hollow waist tube 1, a waist bar 2 slidably connected inside the hollow waist tube 1, a base plate 3 fixedly connected to one end of the hollow waist tube 1, a plurality of suction cups 4 provided on one side of the base plate 3, and a support component provided in the middle of the hollow waist tube 1. The suction cups 4 facilitate a firm grip on the ground and reduce slippage.

[0033] The support assembly includes a sliding sleeve 5, which is slidably connected to the outside of the hollow waist tube 1. A connecting groove 6 is provided on one side of the sliding sleeve 5, and two fixing blocks 7 are fixedly connected to one side of the sliding sleeve 5. A stud 8 passes through the middle of the two fixing blocks 7. A knob 9 is fixedly connected to one end of the stud 8, and a nut 10 is threadedly connected to the other end of the stud 8. The nut 10 is fixedly connected to the connecting groove 6 on the upper surface of one of the fixing blocks 7, which facilitates fixing the position of the sliding sleeve 5 when it is compressed. The stud 8 facilitates applying pressure to the two fixing blocks 7, thereby facilitating the adjustment of the position of the sliding sleeve 5 and the rotation angle of the connecting block 11.

[0034] As attached Figure 3 As shown, a connecting block 11 is rotatably connected between two fixed blocks 7. A stud 8 passes through the middle of the connecting block 11. A hollow support tube 12 is fixedly connected to one side of the connecting block 11. A fixed sleeve 13 is fixedly connected to one end of both the hollow waist tube 1 and the hollow support tube 12. A four-jaw sleeve 14 is fixedly connected to one side of the fixed sleeve 13. A threaded groove 15 is opened on the outside of the four-jaw sleeve 14. The hollow support tube 12 can provide support when the lower jaw support 18 is lifted. The four-jaw sleeve 14 slowly closes under the pressure of the threaded sleeve 17, which facilitates the fixing of the adjusted waist bar 2 and the support rod 16.

[0035] As attached Figure 1As shown, the hollow support 12 has a sliding connection to the support rod 16, which facilitates the adjustment of the height of the jaw support 18 and provides support for the jaw support 18.

[0036] As attached Figure 5 As shown, both the support rod 16 and the waist rod 2 are slidably connected to a threaded sleeve 17 at one end, which facilitates the four-jaw sleeve 14 to converge under the action of the thread.

[0037] As attached Figure 6 As shown, the other end of the support rod 16 is fixedly connected to a chin rest 18. The chin rest 18 has a rubber pad 19 inside. The rubber pad 19 helps to support the chin and provides protection, improving comfort during use.

[0038] As attached Figure 1 As shown, a limiting component is provided at the other end of the waist tube 2. The limiting component includes a butterfly buckle 20, which is fixedly connected to the other end of the waist tube 2. A connecting strap 21 is provided on one side of the butterfly buckle 20. A female buckle 22 is provided at one end of the connecting strap 21. A female buckle 23 is provided inside the female buckle 22. A waist belt 24 is provided on one side of the female buckle 23. One end of the waist belt 24 is provided on the other side of the butterfly buckle 20. An adjusting buckle 25 is provided on the outside of the waist belt 24. A limiting sleeve 26 is fixedly connected to the middle of the hollow waist tube 1. The limiting sleeve 26 is made of plastic. The female buckle 22 and the female buckle 23 are interlocked. The adjusting buckle 25 facilitates the adjustment of the inner diameter of the waist belt 24. The limiting sleeve 26 facilitates the limiting and storage of the hollow waist tube 12 when it is not in use.

[0039] Working principle: When in use, the base plate 3 is first attached to the ground using multiple suction cups 4. At this time, the hollow waist tube 1 is in an upright state. Then, according to the user's height, the height of the waist belt 24 is adjusted by twisting the threaded sleeve 17 on the waist rod 2, so that the threaded sleeve 17 is twisted out of the four-claw sleeve 14, allowing the waist rod 2 to slide. After adjusting the length of the waist rod 2 extending inside the hollow waist tube 1, the threaded sleeve 17 is twisted back to the outside of the thread groove 15, so that the threaded sleeve 17 presses against the four-claw sleeve 14, and the four-claw sleeve 14 firmly grips the waist rod 2, thereby fixing the position of the waist rod 2. Then, the female buckle 22 and the female buckle 23 are separated, and the waist belt 24 is wrapped around the waist. Then, the female buckle 22 and the female buckle 23 are inserted. Then, the inner size of the waist belt 24 is adjusted using the adjusting buckle 25, so that the waist belt 24 fits against the user's waist, thereby supporting the waist.

[0040] Then, turn knob 9 to rotate stud 8. Stud 8 slowly descends inside nut 10 under the action of the thread. At this time, the two fixing blocks 7 release the clamping force on connecting block 11, allowing connecting block 11 to rotate. At the same time, sliding sleeve 5 can slide. After sliding sleeve 5 slides to a suitable position outside hollow waist tube 1 according to the user's needs, rotate hollow support tube 12 to the user's suitable rotation angle, and turn knob 9. Under the action of nut 10, stud 8 will slowly move, causing the two fixing blocks 7 to squeeze each other tightly. While limiting the connection block 11, the sliding sleeve 5 is fixed in position by squeezing each other in the opening of connecting groove 6. Then, according to the adjustment method of hollow waist tube 1 and waist bar 2, adjust the length of the support rod 16 extending inside hollow support tube 12, and place the chin on the chin support 18 to straighten the back and support the sitting posture.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
