Problems solved by technology

[0004] However, there is no professional test device for the static stability test of wheelchairs at present. Therefore, through the research on the static stability test standards of wheelchairs at home and abroad, master the requirements and methods of the static stability test of wheelchairs and obtain some important parameters. Based on this Therefore, it is of great significance to develop a static stability test device for wheelchairs, which can evaluate the safety and effectiveness of the production and use of wheelchairs.

Abstract

The invention discloses a wheelchairs static stability test device comprising a base, a test platform, a lead screw, a handle, a baffle guide rail, a baffle, a roll-over protective mechanism guide rail, a roll-over protective mechanism, a pressure sensor, an angle sensor, a fixed lock ring, a supporting rod, an angle display device and a pressure display device. After the test device of the invention is used to test the wheelchairs forward roll-over, backward roll-over and side roll-over stability performance, the wheelchairs static stability can be evaluated well, and advantages of simple structure and convenient operation can be realized.

Description

technical field [0001] The invention relates to a test device, in particular to a wheelchair static stability test device. Background technique [0002] A wheelchair is a tool used to help people with limited walking or freedom of movement get around. In the process of people's life, with the growth of age, disease and trauma, the walking function of some people will be greatly affected. At this time, the use of some auxiliary tools can enhance or replace the patient's walking function and help the patient achieve a certain degree of freedom of movement. The most effective and common of these aids is the wheelchair. There are mainly 25 measurement items for the performance testing of wheelchairs. Combined with the test content of each testing item, the relevant components and overall functions of the wheelchair are tested to test its performance. Static stability experiment is also an important part of it. Static stability is an index used to evaluate the stability of wh...
