Technical Field
[0001] The invention relates to the field of massage chair testing, and in particular to a silent testing device for massage chairs. Background Art
[0002] The principle of massage chair is to use mechanical rolling force and mechanical force to perform massage. Artificial massage can dredge the meridians, circulate qi and blood, and maintain the balance of yin and yang in the body. Therefore, after massage, you can feel the muscles relax, the joints are flexible, and you can be refreshed and relieve fatigue, which plays an important role in ensuring good health.
[0003] The massage chair may generate noise when in use. When adjusting the angle and height, as well as the vibration during massage, noise will be generated. Noise will affect people's comfort. The existing silent test of massage chairs is to place them in a silent box for testing. The silent box has high requirements for noise, which is generally 30 decibels. It is expensive and limited. Therefore, it is urgent to design a silent test device for massage chairs to solve the silent test problem of massage chairs. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The height of the device can be adjusted by adjusting the fastening screws of the present invention, so that the first airbag and the second airbag can fit the massage chair. The first airbag and the second airbag are arranged to be in close contact with the massage chair. The noise of the massage chair can be detected by cavity sound transmission through the transmission of sound by the airbags, and it is not affected by the external environment. There is no need to place the massage chair in a soundproof box for detection, so that the detection range is wider. Pressure is applied by the first hydraulic cylinder and the second hydraulic cylinder to simulate a person sitting on the massage chair. By applying pressure, the situation of noise generated during normal use can be judged, and the comfort of the massage chair can be further increased, and the massage chair can be prevented from generating large noise. The noise generated by the massage chair can be detected more directly. The conveyor belt can be used to facilitate the transmission of the massage chair. The device can be used on an assembly line for detection, and the operation is relatively convenient. The first airbag and the second airbag are inflated by an air pump, so that the first airbag and the second airbag are more closely fitted to the massage chair, thereby improving the sound transmission effect and testing the noise of the massage chair. The present invention changes the medium of sound transmission by means of cavity sound transmission, so that the noise condition of the massage chair can be intuitively known, and the noise condition during the use of the massage chair can be detected.
