The first worm wheel 22 and the first worm 122 have self-locking property, so that the chair back 2 can not rotate by itself after the chair back 2 is adjusted to a proper angle.

Referring to fig. 3 and 7, in order to increase the connection strength between the seat back 2 and the seat body 1 when the seat back 2 is adjusted to the horizontal state, the seat body 1 is provided with a first abutting portion 161 and a first hinge portion 16, the seat back 2 is provided with a second abutting portion 261 and a second hinge portion 26, the first hinge portion 16 is hinged to the second hinge portion 26, and when the seat back 2 is in the horizontal state, the first abutting portion 161 abuts against the second abutting portion 261 and the first hinge portion 16 is hinged to the second hinge portion 26, so that the possibility of shaking of the seat back 2 can be reduced. In order to further improve the stability of the chair back 2 in the horizontal state, a first supporting leg 23 is hinged to one end of the chair back 2, which is far away from the chair body 1, through a first hinge frame 24, and the first supporting leg 23 is oppositely arranged along the width direction of the chair back 2. In order to reduce the possibility of rotation when the first supporting leg 23 supports, so that the first baffle 241 is fixedly connected to the end of the first hinge frame 24 away from the chair body 1, and when the first supporting leg 23 is perpendicular to the chair back 2, the first supporting leg 23 abuts against the first baffle 241, in practical application, the first supporting leg 23 often needs to incline slightly towards the side away from the chair body 1, and under the influence of gravity, the first supporting leg 23 is difficult to rotate towards the chair body 1. In order to facilitate the folding of the first supporting leg 23, a first supporting frame 25 for the first supporting leg 23 to be clamped is arranged at one end of the chair back 2 close to the chair body 1, and the first supporting frame 25 clamps the first supporting leg 23 by means of the elasticity of the material. The first supporting leg 23 has a length corresponding to the moving supporting wheel 11.

Referring to fig. 5, one end of the foot rest 3 close to the chair body 1 is fixedly connected with a second rotating shaft 32, and the second rotating shaft 32 is hinged with the chair body 1 to realize the rotation of the foot rest 3; a second worm wheel 33 is coaxially fixed on the second rotating shaft 32, a second driving device 13 for driving the second worm wheel is arranged at the bottom of the chair body 1, the second driving device 13 comprises a second driving motor 131 and a second worm, an output shaft of the second driving motor 131 is coaxially fixed with a second worm 132, the second worm 132 is meshed with the second worm wheel 33, the second driving motor 131 rotates to drive the second worm 132 to rotate, and the second worm 132 drives the second worm wheel 33 to rotate, so that the angle of the foot rest 3 can be adjusted. The second worm wheel 33 and the second worm 132 have self-locking property, so that the foot rest 3 does not rotate by itself after the foot rest 3 is adjusted to a proper angle.

Referring to fig. 2 and 8, in order to improve the connection strength between the leg 3 and the chair body 1 when the leg 3 is adjusted to the horizontal state, the chair body 1 is provided with a third contact portion 163 and a third hinge portion 162, the leg 3 is provided with a fourth contact portion 371 and a fourth hinge portion 37, the third hinge portion 162 is hinged to the fourth hinge portion 37, and when the leg 3 is in the horizontal state, the third contact portion 163 is in contact with the fourth contact portion 371, and the possibility of the leg 3 shaking can be reduced in cooperation with the hinge connection between the third hinge portion 162 and the fourth hinge portion 37. In order to further improve the stability of the leg support 3 in the horizontal state, a second supporting leg 34 is connected to one end of the leg support 3 away from the chair body 1 through a second hinge frame 35, and the second supporting leg 34 is oppositely arranged along the width direction of the leg support 3. In order to reduce the possibility of rotation of the second support leg 34 during supporting, the second baffle 351 is fixedly connected to one end of the second hinge frame 35 far away from the chair body 1, and when the second support leg 34 is perpendicular to the foot rest 3, the second support leg 34 abuts against the second baffle 351, in practical application, the second support leg 34 often needs to slightly incline towards one side far away from the chair body 1, and is influenced by gravity, and the second support leg 34 is difficult to rotate towards the chair body 1. In order to facilitate the folding of the second supporting leg 34, a second supporting frame 36 for the second supporting leg 34 to be clipped in is disposed at one end of the leg support 3 close to the chair body 1, and the second supporting frame 36 clips the second supporting leg 34 by means of the elasticity of the material itself. The length of the second support foot 34 corresponds to the length of the mobile support wheel 11.

Referring to fig. 1 and 7, one end of the chair back 2 close to the headrest 5 is rotatably connected with a screw rod 15, the screw rod 15 is driven by a third driving motor 14 installed in the chair back 2, one end of the screw rod 15 far away from the chair back 2 is in threaded connection with the headrest 5, two ends of the screw rod 15 are respectively provided with a guide column 51, one end of each guide column 51 is fixedly connected with the headrest 5, and the other end of each guide column slides in the chair back 2. The third driving motor 14 rotates to adjust the height of the headrest 5. The handle 4 is provided with a control device 41, and the control device 41 is electrically connected with the first driving motor 121, the second driving motor 131 and the third driving motor 14 and is used for controlling the adjustment of the chair back 2, the foot supports 3 and the head cushion 5. The first driving motor 121, the second driving motor 131 and the third driving motor 14 are all locking motors, and output shafts do not rotate in a non-working state, and the possibility of autonomous rotation of the chair back 2 and the foot rest 3 is reduced by matching with self-locking of worm and gear transmission.

The implementation process of the embodiment is as follows: when a user needs to lie down in noon break, an electric signal is sent to the first driving motor 121 through the control device 41, and the first driving motor 121 drives the chair back 2 to rotate until the chair back reaches the horizontal position; then, an electric signal is sent to the second driving motor 131 through the control device 41, and the second driving motor 131 drives the foot rest 3 to move to the horizontal position; the first supporting leg 23 and the second supporting leg 34 are respectively opened to be respectively abutted against the first baffle 241 and the second baffle 351, and at this time, the user can lie down and take a lunch break on the office chair.
