DETAILED DESCRIPTION

[0017] To further illustrate the present application, the following description will be made in conjunction with the accompanying drawings. It is particularly pointed out that the embodiments described below are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0018] Referring to Figure 1 and Figure 2 The present embodiment provides a multifunctional chair for preventing work-related musculoskeletal disorders, which comprises a chair seat 10, a chair back 20 arranged on one side of the top end of the chair seat 10, and a liftable supporting structure 30 arranged at the bottom of the chair seat 10. A buckle groove is arranged on the chair back 20, and a lumbar pillow 40 is detachably arranged on the buckle groove. A lifting assembly 50 is arranged on the back of the chair back 20. The top of the lifting assembly 50 is provided with a mounting seat 11. The top of the mounting seat 11 is provided with a rotating assembly 60. The rotating assembly 60 is connected with a headrest 70. The headrest 70 comprises a soft arc-shaped pillow 71, a hard arc-shaped pillow 72 arranged on the back of the soft arc-shaped pillow 71, and a connecting seat connected to the bottom of the soft arc-shaped pillow 71 and the hard arc-shaped pillow 72. The connecting seat is connected with the rotating assembly 60. The soft arc-shaped pillow 71 and the hard arc-shaped pillow 72 are both provided with a plurality of through ventilation holes.

[0019] Preferably, the air vents include a central circularly arranged central air vent 73 and a radially arranged edge air vent 74 arranged radially around the central air vent, the diameter of the central air vent 73 being larger than that of the edge air vent 74. Firstly, the central air vent 73 is designed with a larger diameter, which can effectively improve the air permeability of the central region of the backrest 70, ensuring smooth air circulation in this region when the user sits for a long time, reducing the accumulation of heat and moisture, and thus improving comfort. Secondly, the radially arranged edge air vent 74 has a smaller diameter, which enhances the support of the edge region while maintaining air permeability, making the entire backrest 70 have uniform ventilation effect.

[0020] Preferably, the soft arc-shaped pillow 71 and the hard arc-shaped pillow 72 each include an arc-shaped support base plate 75 and a gasket layer 76 arranged on the arc. Firstly, the arc-shaped support base plate 75 can provide stable basic support for the backrest 70, ensuring that its shape can closely fit the back curve of the human body, thus providing better comfort and support effect. Secondly, the gasket layer 76 is attached to the arc-shaped support base plate 75, making the backrest 70 more soft and comfortable when contacting the human body, effectively relieving fatigue when relying for a long time. Through the above design, the soft arc-shaped pillow 71 can provide a soft touch while still ensuring good support, while the hard arc-shaped pillow 72 can provide stronger support while reducing discomfort caused by possible hardness through the gasket layer 76. When in use, users can choose the appropriate backrest 70 according to their own needs, enjoy personalized comfort experience, and effectively prevent work-related musculoskeletal disorders caused by poor sitting posture.

[0021] Preferably, the hardness of the gasket layer 76 of the soft arc-shaped pillow 71 is much smaller than that of the gasket layer 76 of the hard arc-shaped pillow 72. Firstly, by adjusting the hardness of the gasket layer 76, users can choose a more suitable backrest 70 according to their personal comfort needs. The soft arc-shaped pillow 71, due to its lower hardness, can provide softer support, making it suitable for use when relaxation or back pressure relief is needed. It can also reduce the feeling of oppression on the body during long-term use, helping to relieve muscle tension and fatigue caused by prolonged sitting. On the other hand, the gasket layer 76 of the hard arc-shaped pillow 72 has higher hardness, providing more solid support. This makes the hard arc-shaped pillow 72 more suitable for scenarios that require enhanced back support or maintaining good sitting posture at work. Higher hardness can help users maintain the natural curvature of the spine, thereby preventing work-related musculoskeletal disorders such as lumbar disc herniation or scoliosis caused by poor sitting posture.

[0022] It is also possible that the lifting assembly 50 is a lifting motor and a lead screw structure connected to the lifting motor. By introducing a lifting motor, users can easily achieve automatic adjustment of the height of the headrest 70 without manual operation, greatly improving the convenience and efficiency of use. At the same time, the precise control of the motor also ensures the smoothness and accuracy of the adjustment process. While the lead screw structure, as a transmission component of the lifting motor, has good load capacity and stability. It can ensure that the headrest 70 remains stable during lifting without shaking or tilting, thereby providing more stable and comfortable support for users.

[0023] Preferably, the rotating assembly 60 comprises a rotating seat 61 and a rotating rod 62. The rotating seat 61 is arranged on the top of the mounting seat 11, and a rotating hole 63 is formed in the rotating seat 61. A plurality of pairs of clamping grooves are formed on the side of the rotating hole 63. One end of the rotating rod 62 is rotatably arranged in the rotating hole 63, and the other end of the rotating rod 62 is arranged with the headrest 70. The side of the rotating rod 62 is arranged with a telescopic buckle which is adapted to the clamping grooves.

[0024] When the user needs to adjust the angle of the headrest 70, the user presses the telescopic buckle, which retracts into the interior, and can easily rotate the rotating rod 62. Since one end of the rotating rod 62 is arranged in the rotating hole 63 of the rotating seat 61, it can rotate freely within a certain range, thereby changing the angle of the headrest 70. When the user finds the appropriate angle, the telescopic buckle on the side of the rotating rod 62 will automatically engage with the corresponding clamping grooves in the rotating hole 63. At this time, the rotating rod 62 is locked in the current position, ensuring that the headrest 70 remains at the angle selected by the user. If further adjustment is needed, the user only needs to disengage the clamping and continue to rotate the rotating rod 62 to a new angle.

[0025] It is also possible that the rotating assembly 60 is a rotating motor. By driving the rotating motor, users can easily adjust the angle of the headrest 70 without manual operation.

[0026] Preferably, the chair seat 10 is provided with a sensor, and the sensor is connected with an alarm arranged on the back of the chair back 20. In this application, the sensor is a pressure sensor. Through the monitoring of the pressure sensor, the user's sitting posture can be monitored in real time, and the alarm can be reminded according to the sitting time, helping users to develop good work and rest habits and avoid discomfort caused by long-term fixed sitting posture.
