Description

A kind of electric bed testing equipment

technical field

The invention relates to the field of electric bed detection, in particular to an electric bed detection device.

Background technique

Among the various components of the electric bed, the electric push rod, bed board, bed frame and other structural parts mainly bear the load brought by the user of the electric bed. Serious defects such as the bed board and bed frame may lead to damage to the electric bed, which is harmful to the user. The personal safety of the electric bed poses a certain threat. The failure of the electric push rod will cause the bed board to be unable to be lifted and turned or the height of the lifting and turning is insufficient, resulting in functional defects and reduced comfort of the electric bed.

That is to say, the carrying capacity and defects of the electric bed directly affect the comfort of the electric bed user, so it is very necessary to carry out the load test on the finished electric bed, which is one of the main detection methods to improve product quality and reduce customer complaints. Therefore, there is a need for an electric bed load detection that can check the structural strength of the bed board, bed frame, etc., and can also detect the height of the electric push rod to lift and turn the bed board.

At present, the common electric bed finished product detection methods are as follows: (1) real-life loading measurement method; (2) load loading height detection method.

The above detection methods have practical applications in factories. Among them, the method (1) real-life loading measurement method consumes the most manpower and has the lowest efficiency, and is suitable for laboratory use or small-scale production; because the bed surface is mostly soft material, it is easy to deform after loading. , resulting in a low measurement accuracy of the load angle detection method. Method (2) is like an intelligent bed detection device with the existing patent application number of 202020835017.X, which changes the angle measurement to the height measurement, which greatly improves the measurement accuracy, but the above detection device can only be applied to one Models of electric bed testing, for multiple models of electric beds, it is necessary to customize the testing equipment of the corresponding size, which undoubtedly increases the testing cost of the electric bed. In addition, in the above-mentioned patent, the base surface for placing the electric bed is located directly below the multiple detection mechanisms, which also leads to the fact that when the electric bed is placed on the base surface, the multiple detection mechanisms and racks will undoubtedly affect the placement of the electric bed. The process produces interference blocking, which is inconvenient to use.
