Abstract

The invention provides a fatigue strength test device for a parking brake of a wheelchair. The fatigue strength test device comprises a base, a support mechanism, a motor driving mechanism, a rear wheel driving mechanism of the wheelchair, a front wheel driving mechanism of the wheelchair and a parking brake repetitive operation mechanism of the wheelchair, wherein the rear wheel driving mechanism of the wheelchair can drive two rear wheels of the wheelchair to be tested to rotate; the front wheel driving mechanism of the wheelchair can drive the two front wheels of the wheelchair to be tested to rotate; and the parking brake repetitive operation mechanism of the wheelchair can carry out repetitive braking on the parking brake of the wheelchair to be tested. In the invention, the specified times of repetitive operation are carried out on the parking brake of wheelchair so as to assess the performance of the brake; and the fatigue strength test device has simple structure and is convenient to operate.

Description

technical field [0001] The invention relates to a testing device, in particular to a device for testing the fatigue strength of a parking brake of a wheelchair. Background technique [0002] The performance of the parking brake of the wheelchair will directly affect the safety and reliability of the wheelchair. In order to ensure the safety of pedestrians, it is necessary to test the performance of the wheelchair parking brake to determine its fatigue strength (service life), and to arrange a reasonable maintenance cycle accordingly. At present, the wheelchairs produced in China can be roughly divided into two categories: manual wheelchairs and electric wheelchairs. Among them, manual wheelchairs account for most of the market share, while electric wheelchairs are still in the growth stage in the domestic market. Since manual wheelchairs and some electric wheelchairs use mechanical manual brakes, the development of a wheelchair parking brake fatigue strength test device ha...
