AI Technical Summary

Technical Problem

The existing hinges are mainly manually opened and closed in household appliances, and cannot achieve intelligent control, which limits the degree of intelligence and convenience of household appliances.

Method used

An electric hinge is designed, using a combination of power unit, actuator unit, connection unit and output unit. The screw and slider are driven by the motor and gear to drive the pull rod and the inner bracket to realize the electric opening and closing of the outer shell. There is a switching between the driving wheel and the driven wheel in a tooth-closing state, which can not only realize electric opening and closing, but also manual opening and closing.

Benefits of technology

It realizes the electrification control of hinges in household appliances, improves the intelligence of the product, and is more convenient to use. It is suitable for microwave ovens, ovens and other products. It can automatically open the machine door according to the program to improve cooking efficiency and food quality.

Abstract

The row unit comprises a screw rod which is driven by a motor through a gear to rotate and a sliding block which is assembled at the screw rod in a limiting manner; the connecting unit comprises a sliding block connected to the execution unit and a pull rod which is driven by the sliding block to move in the shell, and an inner support connected with the pull rod; the output unit is connected to the shell and the inner support, and the output unit rotates relative to the shell so as to be switched between a first state and a second state; the gear comprises a driving wheel and a driven wheel which are meshed with each other, the driving wheel is connected with an output shaft of the motor, the driven wheel is connected with the screw rod, and a smooth area is arranged on the driving wheel or the driven wheel, so that the driving wheel and the driven wheel are disengaged from each other. According to the electric hinge, the driving wheel and the driven wheel are switched between the engaged state and the disengaged state, and electric opening and closing and manual opening and closing of the hinge can be achieved.
