Problems solved by technology

Nowadays, wheelchairs have become an indispensable means of transportation for the elderly and the disabled. Because of their wide range of applications, as long as the user has clear consciousness and normal cognitive ability, using a wheelchair is a good choice. Therefore, the wheelchair The market demand is increasing, but compared with the wheelchairs produced abroad, the production and sales market of domestically produced wheelchairs is still in a chaotic state. There are problems such as poor product quality, low grade, few varieties, and small scale of production other serious problems

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Referring to GB / T18029 and the actual structural application of the wheelchair test dummy, the quality grades of the dummy are 25kg, 50kg, 75kg, 100kg and 25*4N (N>=4)kg. A dummy may be constructed from the following materials:

[0017] 1. (15±1)mm plywood or plastic: connect the back structure and backboard

[0018] 2. lightweight aluminum strips: the frame for the dummy

[0019] 3. The steel block (mass is about 6kg): internal counterweight

[0020] 4. The steel block (mass is about 3kg): internal counterweight

[0021] 5. (30±10)mm*(20±1)mm plastic or nylon parts: fixed weight

[0022] 6. (30±10)mm*(12±1)mm plastic or nylon parts: fixed weight

[0023] 7. (15±3)mm high-density closed-cell foam material: impact resistance

[0024] 8. (50±3)mm rigid open-cell foam material: shock absorption

[0025] During the test, a dummy correspo...

Abstract

The invention relates to a dummy for wheelchair performance testing, which comprises a back plate, a back structure, a seat structure, thigh plates and a shank structure, wherein the back plate is connected with the back structure through plywood, and used for reducing vibration and friction between the back structure and a wheelchair; the back structure is connected with the seat structure in a rotated manner for simulating weights and gravity centers of buttocks and thighs of a human body; the thigh plates are fixedly connected to the lower surface of the seat structure for simulating shapes of the buttocks and thighs of the human body; and the front end of the seat structure is provided with the shank structure for simulating weights and gravity centers of shanks of the human body. The dummy conforming to gravity center distribution and positions of the human body is manufactured by adopting reasonable materials and using knowledge of modern mechanical design, is used for replacing the human body in quality and safety tests for performances such as static stability, fatigue strength and impact-resistance strength, and is simple in design, is practical and reliable.

Description

technical field [0001] The invention relates to a dummy for testing, in particular to a dummy for performance testing of wheelchairs. Background technique [0002] The wheelchair is a very important rehabilitation tool. It is not only a means of transportation for all physically disabled people, but more importantly, it enables them to participate in social activities with the help of wheelchairs, integrate into society, and live a better life. my country is the country with the largest elderly population in the world and one of the countries with the fastest aging population. Nowadays, wheelchairs have become an indispensable means of transportation for the elderly and the disabled. Because of their wide range of applications, as long as the user has clear consciousness and normal cognitive ability, using a wheelchair is a good choice. Therefore, the wheelchair The market demand is increasing, but compared with the wheelchairs produced abroad, the production and sales mark...
