2. The smart chair of claim 1, wherein: after the lifting mechanism is lifted, the infrared detector can perform secondary induction, if the obstacle can still be detected, the processor sends a signal to the avoidance module, and the intelligent chair enters an avoidance mode.

3. The smart chair of claim 1, wherein: the surface of the cushion is provided with a stop button.

4. The intelligent speed-regulating chair according to claim 1, characterized in that: and a power supply part is arranged in the control box and is electrically connected with the master control device.

5. The intelligent speed-regulating chair according to claim 1, characterized in that: the avoidance module and the stop module are electrically connected with the universal wheel respectively.

Technical Field

The invention relates to the field of automation, in particular to an intelligent chair.

Background

With the rapid development of smart homes, products such as household appliances and homes of traditional homes are endowed with intelligent functions. The existing intelligent chair, for example, under the control of a user, drives the chair to move by itself through its own driving device, thereby realizing the function of the intelligent chair to move autonomously.

However, in the existing intelligent chair technology, the intelligent chair usually only selects to avoid the obstacle when facing the obstacle, thereby increasing the journey invisibly and being not intelligent enough.

Disclosure of Invention

The invention aims to overcome the problems in the prior art and provides an intelligent chair capable of automatically advancing or avoiding according to the size of an obstacle.

In order to achieve the aim, the intelligent chair comprises a cushion, the rear end of the cushion is connected with a backrest, the bottom of the cushion is connected with chair legs, universal wheels are arranged at the bottoms of the chair legs,

the middle parts of the chair legs are provided with lifting mechanisms, and each lifting mechanism comprises an air cylinder and a push rod connected with the air cylinder; the lifting mechanism is provided with an infrared detector for sensing obstacles;

the cushion bottom still is equipped with the control box, be equipped with treater, be used for driving actuating cylinder's drive module, dodge the module and stop the module in the control box.

Further, after the lifting mechanism is lifted, the infrared detector can perform secondary induction, if the obstacle can still be detected, the processor sends a signal to the avoidance module, and the intelligent chair enters an avoidance mode.

Further, the surface of the cushion is provided with a stop button.

Furthermore, a power supply part is arranged in the control box and electrically connected with the master control device.

Further, the avoidance module and the stop module are respectively electrically connected with the universal wheel.

By means of the technical scheme, the intelligent chair at least has the following advantages:

according to the invention, the lifting mechanism is arranged in the chair leg, the infrared detector is arranged on the lifting mechanism, the infrared detector can carry out secondary detection after being lifted along with the lifting mechanism, and if the obstacle can be detected, the processor selects the avoidance mode. The intelligent chair can select a corresponding forward mode according to the size of the obstacle instead of detouring around the obstacle at once, and can pass through the intelligent chair in a straight line when the obstacle is small, so that the travel is shortened, and the energy is saved.
