Description

Technical Field

[0001] This utility model belongs to the field of chair technology, and in particular relates to a chair that adapts to the shape of the human body, specifically a gaming chair whose backrest follows the user's back and can automatically conform to the spine. Background Technology

[0002] The target customer group for gaming chairs is mainly e-sports players. When using them, users often need to maintain a seated posture for a long time to operate the computer. Therefore, compared with ordinary chairs, gaming chairs have higher requirements for comfort.

[0003] A spinal massage chair is disclosed in Chinese utility model patent with announcement number CN221691856U. Through the meshing of the active gear and the driven gear, the user can operate the control panel to start the motor according to their own massage posture habits. The output shaft of the motor drives the active gear and the driven gear to drive each other. The driven gear drives the driven rotating shaft to adjust the inclination of the chair back. The driven rotating shaft drives the drive frame, thereby driving the chair back of the massage chair to adjust the inclination accordingly. This allows the user to flexibly adjust the massage angle according to their own comfort, improving the user's comfort.

[0004] However, the chairs mentioned above require manual adjustment of the backrest to conform to the spine during use. However, esports players often lean forward, so the backrest cannot always be in contact with the player's back, resulting in inadequate support for the player's spine. Utility Model Content

[0005] The purpose of this invention is to provide a gaming chair that automatically conforms to the spine. The backrest of this gaming chair follows the player's movements, always fitting against the player's back and automatically conforming to and supporting the player's spine.

[0006] The technical solution adopted by this utility model to solve the above problems is: an automatic e-sports chair that conforms to the spine, including a support component, a support plate disposed on the support component, a backrest disposed on the support plate, and a deflection component connecting the backrest and the support plate.

[0007] The deflection assembly includes a pressure plate slidably disposed in the inner cavity of the support plate, a plurality of first piston rods fixedly connected at intervals to the bottom of the pressure plate, a fixed cylinder slidably connected to the outside of the first piston rods and fixedly connected to the bottom of the inner wall of the support plate, a vent pipe connected to the fixed cylinder through a branch pipe, a limiting cylinder connected to one end of the vent pipe, a second piston rod slidably connected to the inside of the limiting cylinder, a movable toothed plate fixedly connected to one end of the second piston rod, and a main gear meshing with the movable toothed plate.

[0008] One end of the intermediate shaft of the main gear is fixedly connected to the backrest.

[0009] A further preferred technical solution is that: the support component includes a chassis, and a number of connecting plates are fixedly connected to the chassis at intervals; an adjustment component is fixedly connected to the top of the chassis.

[0010] A further preferred technical solution is as follows: the adjusting component includes a connecting cylinder, a lifting rod slidably connected inside the connecting cylinder and fixedly connected at its bottom end to the top of the chassis, a threaded rod threadedly connected to a threaded hole inside the lifting rod and rotatably connected at its top end to the top of the inner wall of the connecting cylinder, a first helical gear fixedly sleeved on the threaded rod, a second helical gear meshing with the first helical gear, an L-shaped plate fixedly connected to the connecting cylinder, a handrail fixedly connected to the top of the L-shaped plate, an L-shaped groove disposed inside the L-shaped plate, a transmission helical gear fixedly connected to one end of the intermediate shaft of the second helical gear, a driving helical gear meshing with the transmission helical gear, and a vertical rod penetrating through the shaft of the driving helical gear and rotatably connected at its bottom end to the inner wall of the L-shaped groove; a support plate is fixedly connected to the top of the connecting cylinder, and the intermediate shaft of the second helical gear is installed inside the L-shaped groove.

[0011] A further preferred technical solution is that two small bearings are installed on the outer side of the main gear intermediate shaft, and the outer side of the small bearings is installed on the surface of the support plate.

[0012] A further preferred technical solution is that: a straight groove is provided at the bottom of the inner wall of the support plate, and the movable toothed plate is slidably disposed inside the straight groove.

[0013] A further preferred technical solution is that: a number of reset springs are fixedly connected at intervals to the bottom of the inner wall of the support plate, and the top of the reset springs is fixedly connected to the bottom of the pressure plate.

[0014] A further preferred technical solution is that a long strip plate is fixedly connected to the pressure plate, and the inner wall of the support plate is provided with a lifting groove for installing the long strip plate.

[0015] A further preferred technical solution is that a locking block is fixedly connected to the lifting rod, and a vertical groove for the locking block to move is provided on the inner wall of the connecting cylinder.

[0016] A further preferred technical solution is that: a rotary bearing is installed on the inner wall of the connecting cylinder, the intermediate shaft of the second helical gear is installed inside the rotary bearing, a seated bearing is installed on the outer side of the intermediate shaft of the second helical gear, and the bottom of the seated bearing is fixedly connected to the bottom of the inner wall of the L-shaped groove.

[0017] A further preferred technical solution is that a U-shaped handle is rotatably connected to the top of the vertical rod.

[0018] In summary, this utility model has the following advantages:

[0019] 1. This utility model, by setting up a deflection component, allows the user to sit on the pressure plate during use. This causes the pressure plate to move downwards along with the first piston rod, which in turn pushes the gas in the fixed cylinder into the vent pipe. This allows the gas in the vent pipe to enter the limiting cylinder. This gas then pushes the second piston rod, causing the second piston rod to move to the left along with the moving gear plate. Under the action of the moving gear plate, the main gear deflects the backrest, causing the backrest to deflect towards the user's back. This allows the backrest to automatically conform to the user's back when the user sits down.

[0020] 2. This utility model, by setting an adjustment component, allows the user to adjust the height of the device according to their body size before use. By pulling up the U-shaped handle and rotating the vertical rod, the vertical rod drives the driving helical gear to rotate. Under the action of the driving helical gear, the transmission helical gear drives the second helical gear to rotate, which in turn drives the threaded rod to rotate. This causes the lifting rod to move vertically, thus achieving the adjustment of the overall length of the lifting rod and the connecting cylinder, and consequently, the adjustment of the device height. The height of the device can be adjusted by rotating the U-shaped handle, eliminating the need for the user to bend over to rotate it. Attached Figure Description

[0031] The implementation principle of an automatically conforming gaming chair in this application embodiment is as follows:

[0032] 1. Before use, adjust the height of the device according to the user's body size. Pull up the U-shaped handle and rotate the vertical rod 11, causing the vertical rod 11 to drive the helical gear 10 to rotate. Under the action of the driving helical gear 10, the transmission helical gear 9 drives the second helical gear 7 to rotate, causing the first helical gear 6 to drive the threaded rod 5 to rotate. This allows the lifting rod 4 to move vertically, realizing the adjustment of the overall length of the lifting rod 4 and the connecting cylinder 3, and thus the adjustment of the device height. The height of the device can be adjusted by rotating the U-shaped handle, eliminating the need for the user to bend over to turn it, making the height adjustment of the device more convenient.

[0033] 2. In use, the user sits on the pressure plate 13, causing the pressure plate 13 to move downwards along with the first piston rod 14. This pushes the gas in the fixed cylinder 15 into the vent pipe 16, allowing the gas in the vent pipe 16 to enter the limiting cylinder 17. This gas then pushes the second piston rod 18, causing the second piston rod 18 to slide along the moving gear plate 19 in the linear groove. Under the action of the moving gear plate 19, the main gear 20 drives the backrest 21 to deflect towards the user's back via the intermediate shaft, thus ensuring that the backrest 21 automatically conforms to the user's back when seated. Furthermore, the distance the backrest 21 can deflect towards the user's back has a limit; when the moving gear plate 19 moves to its limit position to one side, it automatically abuts against the inner wall of the support plate 12, locking the main gear 20 and thus locking the backrest 21.

[0034] 3. When the user leans back, the pressure on the pressure plate 13 will decrease. Under the action of the return spring, the pressure plate 13 moves upward with the first piston rod 14. According to the above mechanical linkage, the backrest 21 can move away from the current position, making it easier for the user to lean back and sit.

[0035] 4. The force of the backrest 21 tilting forward is balanced by the force of the user leaning back after the user sits on the pressure plate 13, and is always against the user's back.

[0036] Furthermore, the same or similar element symbols are used as far as possible in the accompanying drawings and description to refer to the same or similar parts or steps. The drawings are presented in a simplified form and are not drawn to scale. For convenience and clarity only, directional terms such as top, bottom, front, back, left, right, front, back, upward, above, above, below, behind, and front may be used to refer to the drawings.
