[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] refer to Figure 1-8 The ergonomic computer chair includes a chair 1, and armrests 2 are provided on both sides of the chair 1. The armrests 2 include a fixed seat 201, a movable seat 202, and an armrest pad 203. The fixed seat 201 is arranged on the side of the chair 1 and is fixedly connected to the chair 1. An adjustment slot 2011 is provided inside the fixed seat 201, and the movable seat 202 is slidably connected to the inner wall of the adjustment slot 2011. The inner walls on both sides of the adjustment slot 2011 are provided with a plurality of slots 204 arranged at intervals in the vertical direction. A card block 205 that is engaged with each slot 204 is provided on the movable seat 202. In order to improve the stability of the connection between the card block 205 and the card slot 204, the cross-street surfaces of the card block 205 and the card slot 204 are both square structures. The square-structured card block 205 and the card slot 204 can provide a larger contact area, thereby enhancing the stability of the connection between the fixed seat 201 and the movable seat 202, and preventing the armrest from loosening or displacement during use.

[0026] The armrest pad 203 is disposed on the top of the movable seat 202 and is fixedly connected to the movable seat 202 . A fixing assembly is provided in the movable seat 202 to enable each clamping block 205 to be simultaneously separated from the clamping slot 204 .

[0027] The height of the armrest can be adjusted by providing a fixed seat 201, a movable seat 202, a block 205, a slot 204, and a fixing assembly. When the user needs to adjust the height of the armrest, the block 205 can be disengaged from the slot 204 on the fixed seat 201 through the fixing assembly on the movable seat 202. After the block 205 is disengaged from the slot 204, the user can slide the movable seat 202 up and down in the adjustment slot 2011 until the appropriate height is adjusted, and then reinsert the block 205 into the slot 204 through the fixing assembly to fix the position, thereby adjusting the height of the armrest. The height-adjustable armrest can be personalized according to the body shape and sitting posture of different users, in accordance with ergonomic principles, so that the armrest can fit closely to the user's arm, reducing arm and shoulder fatigue during long-term computer use and improving the user's overall comfort.

[0028] Specifically, the fixing assembly includes a connecting plate 3, an elastic member 301, and a pressure rod 302. The elastic member 301 can be a cylindrical compression spring. A accommodating space 303 is provided in the movable seat 202, and both sides of the accommodating space 303 are provided with a slide groove 304. Each block 205 is respectively arranged in the slide groove 304 and is slidably connected to the inner wall of the slide groove 304. Each block 205 is rotatably connected to the connecting plate 3 through a connecting rod 305, and the connecting plate 3 is arranged below the block 205. The connecting rod 305 is connected to the connecting plate 3. One end of the block 205 is connected in a rotatable connection, one end of the elastic member 301 abuts against the bottom of the accommodating space 303, and the other end of the elastic member 301 abuts against the bottom of the connecting plate 3 (the length of the connecting rod 305 is greater than the distance between the rotation point of the connecting rod 305 and the block 205 and the rotation point of the connecting rod 305 and the connecting plate 3), and the pressure rod 302 is arranged on the side of the connecting plate 3 away from the elastic member 301 and is fixedly connected to the connecting plate 3, and one end of the pressure rod 302 extends into the inside of the armrest pad 203.

[0029] An extrusion block 309 is provided on the side of the pressure rod 302 away from the elastic member 301, and the extrusion block 309 is fixedly connected to the pressure rod 302. A sliding groove 310 is provided on the top of the armrest pad 203, and the extrusion block 309 is slidably connected to the inner wall of the sliding groove 310. The horizontal height of the extrusion block 309 is flush with the top of the sliding groove 310. By flushing the height of the extrusion block 309 with the height of the sliding groove 310, it can be ensured that when the user leans on the armrest, the armrest surface will not cause discomfort due to the protrusion, thereby improving the user experience.

[0030] When the user needs to adjust the height of the armrest pad 203, they can press the squeeze block 309 with one hand. The squeeze block 309 will slide downward in the sliding groove 310, causing the pressure rod 302 to drive the connecting plate 3 to move in the direction of the compressed elastic member 301. At the same time, the pressure rod 302 will also move one end of each connecting rod 305, thereby driving the other end of the connecting rod 305 to move the block 205 simultaneously and retract the block 205 on both sides from the slot 204 into the slide groove 304 (because the slide groove 304 limits the vertical freedom of the block 205, so that the block 205 can only move horizontally, the block 205 will retract into the slide groove 304 under the drive of the connecting rod 305), thereby disengaging the block 205. After the block 205 is out of the slot 204, the user can move the movable seat 202 up and down in the adjustment slot 2011 until it is adjusted to the desired height. When the height is adjusted to the desired level, the user releases the pressure lever 302, and the elastic member 301 returns to its original position, pushing the connecting plate 3 upward. The connecting plate 3 drives the block 205 to move within the chute 304 via the connecting rod 305, allowing the block 205 to extend again and be inserted into the corresponding slot 204, completing the fixation.

[0031] Through the fixing assembly provided in this embodiment, the user only needs to press the squeezing block 309 with one hand to complete the height adjustment of the armrest pad 203, without the need for two hands or more complicated operations, thereby improving the convenience of use.

[0032] To prevent the movable seat 202 from rotating during movement or causing the position of the clamping block 205 and the clamping slot 204 to shift, the cross-section of the movable seat 202 and the adjustment slot 2011 is designed to have a square structure. The four edges of the square structure can better contact the inner wall of the adjustment slot 2011, making it difficult for the movable seat 202 to rotate during movement, thereby ensuring the consistency of the position of the clamping block 205 and the clamping slot 204.

[0033] In this embodiment, an extrusion groove 306 is provided at the top of the accommodating space 303. The pressure rod 302 is slidably connected to the inner wall of the extrusion groove 306. Guide grooves 307 are provided on both sides of the extrusion groove 306. Guide blocks 308 are provided on both sides of the pressure rod 302. The guide blocks 308 are slidably connected to the inner wall of the guide groove 307. The provision of the guide blocks 308 and the guide grooves 307 prevents the pressure rod 302 from rotating or dislocating when the user presses the pressure rod 302, thereby preventing the pressure rod 302 from causing the connecting plate 3 to dislocate or shift. This ensures that the elastic member 301 is evenly stressed and increases the service life of the elastic member 301.

[0034] In this embodiment, in order to prevent the block 205 from being offset or misplaced during movement, a guide plate 311 is provided at one end of each block 205 in the accommodating space 303, and a guide rod 312 is provided on both sides of the accommodating space 303. Each guide plate 311 is slidably connected to the guide rod 312. The provided guide rod 312 and guide plate 311 can prevent the block 205 from being offset or misplaced when it moves under the drive of the fixed component, thereby improving the stability of the block 205 during movement.

[0035] Working principle;

[0036] When the user needs to adjust the height of the armrest pad 203, they can press the squeeze block 309 with one hand. The squeeze block 309 will slide downward in the sliding groove 310, causing the pressure rod 302 to drive the connecting plate 3 to move in the direction of the compressed elastic member 301. At the same time, the pressure rod 302 will also move one end of each connecting rod 305, thereby driving the other end of the connecting rod 305 to move the clamping block 205 simultaneously and retract the clamping blocks 205 on both sides from the clamping groove 204 into the sliding groove 304, thereby achieving the disengagement of the clamping block 205. After the clamping block 205 is out of the clamping groove 204, the user can move the movable seat 202 up and down in the adjustment groove 2011 until the desired height is adjusted. When the desired height is reached, the user can release the hand pressing the pressure rod 302, and the elastic member 301 will reset, pushing the connecting plate 3 upward. Connecting plate 3 drives block 205 through connecting rod 305 to move within slot 304, allowing block 205 to re-extend and insert into the corresponding slot 204, securing the computer. The height-adjustable armrests can be customized to suit the user's body shape and sitting posture. This ergonomic design allows the armrests to fit snugly around the user's arms, reducing arm and shoulder fatigue during prolonged computer use and enhancing overall comfort.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
