The invention provides a chair capable of preventing myopia and humpback. The chair comprises a chair body, wherein a fixing base of a first motor is arranged on the outer side of a first armrest of the chair body, the first motor drives a first electric telescopic rod to perform rotation in the forward-backward direction, the first electric telescopic rod is connected with a fixing base of a second motor, the second motor drives a second electric telescopic rod to perform rotation in the leftward-rightward direction, and the second electric telescopic rod is connected with a small desk plate;a fixing base of a third motor is arranged on the outer side of a second armrest, the third motor drives a third electric telescopic rod to perform rotation in the forward-backward direction, the third electric telescopic rod is connected with a fixing base of a fourth motor, and the fourth motor drives a lampshade to perform rotation in the leftward-rightward direction; a first pressure sensor array is arranged on a chair back, a controller determines the height of a user and the sitting position of the user according to the pressure information detected by the first pressure sensor array, according to the height of the user and the sitting position of the user, the controller adjusts the relative position between the small desk plate and the user and also adjusts the output direction ofa light source of the lampshade.
Description
technical field [0001] The invention belongs to the field of educational and teaching supplies, and in particular relates to a chair for preventing myopia and hunchback. Background technique [0002] Traditional chairs often focus on how to keep the user's trunk upright when preventing myopia, but the root cause of myopia is not the straightness of the trunk, but the distance between the eyes and the small table, and the height of different users varies. Similarly, when the position of the tray table is fixed, if the user is tall, the tray table will be too far away from the user, and if the user is short, the tray table will be too close to the user. Obviously, in both cases, a good vision protection effect cannot be obtained, and the anti-myopia effect of traditional chairs is relatively poor. Contents of the invention [0003] The invention provides a chair for preventing myopia and hunchback to solve the problem that traditional chairs for preventing myopia have poor ...
