Problems solved by technology

[0003] When the user finds that an obstacle is encountered during the lifting of the bed frame, the obstacle needs to be removed to ensure that the bed frame continues to move without an obstacle alarm. If the obstacle is not obvious enough or the light is weak, it is not easy for the user to find the obstacle Things that will affect the user experience
If the lift bed is used in the medical industry, if obstacles cannot be removed in time, it may affect medical activities, and serious medical accidents may occur. Therefore, the efficiency of obstacle removal is more important.

Abstract

The invention discloses a method for detecting an obstructed part of an electric bed capable of being retreated when encountering obstructions, belongs to the field of lifting beds, and can remind a user of the specific obstructed position of the electric bed so that the user can quickly remove the obstructions.The method for detecting the obstructed part of the electric bed capable of being retreated when encountering obstructions comprises a bed frame, the bed frame is connected with a lifting mechanism for driving the bed frame to lift; the three sensors are arranged on the bed frame; the method for detecting the obstructed part comprises the following steps: detecting vibration of a bed frame through a sensor; calculating the difference value of the distance between each sensor and the blocked part; and calculating the position of the blocked part on the bed frame through the difference value of the distances.

Description

【Technical field】 [0001] The invention relates to the field of liftable beds, in particular to a method for detecting an obstructed position of a retractable electric bed when encountering an obstruction. 【Background technique】 [0002] The bed frame of the lift bed has a lifting function, and is widely used in home furnishing and medical treatment. During use, if the bed frame encounters an obstacle, it will affect the normal lifting. Therefore, when an obstacle is encountered during the lifting process, the bed frame can be retracted to prevent the bed frame from continuing to move and causing adverse effects. [0003] When the user finds that an obstacle is encountered during the lifting of the bed frame, the obstacle needs to be removed to ensure that the bed frame continues to move without an obstacle alarm. If the obstacle is not obvious enough or the light is weak, it is not easy for the user to find the obstacle Things that will affect the user experience. If the l...
