Electric folding sofa bed

Abstract

The invention belongs to the technical field of electric folding sofa beds, and particularly relates to an electric folding sofa bed. The electric folding sofa bed comprises: a sofa seat which is internally provided with an accommodating cavity; a bed frame which is accommodated in the accommodating cavity of the sofa seat when being folded, and is in a bed state when being unfolded; and a driving device used for driving the bed frame to be unfolded or folded. According to the electric folding sofa bed, rocking bars are used as transmission elements of motor driving force, the force and motion transmission effect is better than that of a lever and a connecting rod, and meanwhile, a first rocking bar and a second rocking bar in the same bending rod form are adopted for jointly bearing and sharing the folding and unfolding motion of all the movable frames of the bed frame. On one hand, the high requirement for the bearing capacity of the rockers when the sofa bed is folded can be reduced, so that the manufacturing cost is reduced, on the other hand, a rocker assembly enables the whole sofa bed to move very stably in the folding and unfolding process, the rotating speed of the motor does not need to be too high, and the service life of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric folding sofa beds, and in particular relates to an electric folding sofa bed. Background technique [0002] With the improvement of living standards, people are more pursuing the comfort of living. Most families will purchase a sofa bed, which is used as a sofa in normal times, and converted into a bed when there are guests staying overnight. This will not only save money, but also reduce space occupation and increase space. utilization rate. [0003] The folding sofa bed generally includes a sofa seat, and the sofa seat has an accommodation space. When the bed frame is in the folded state, it is located in the accommodation space of the sofa seat, and is used as a sofa seat; when the bed frame is in the open state, it is a bed. Most of the sofa beds in the prior art need to be folded manually by the user, and the folding process is relatively complicated, which is not only inconvenient for the...

AI Technical Summary

Problems solved by technology

Most of the sofa beds in the prior art need to be folded manually by the user, and the folding process is relatively complicated, which is not only inconvenient for the user to operate, but also increases the labor intensity of the user, and the sofa bed in the prior art cannot Meet the user's requirements

[0004] Although in the prior art, electric motors are used as the driving source for electric folding of sofa beds, most of them use a single lever or connecting rod to transmit the driving force of the motor, and are responsible for simultaneously driving the folding and opening actions of all bed frames. The disadvantage is that a single lever or connecting rod is responsible for driving the folding and opening actions of all bed frames at the same time. It will inevitably appear that the folding and opening movement of the sofa bed is not stable enough, and at the same time, the performance requirements of the motor are relatively large, which will affect the service life of the motor
