Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of detection equipment technical field, in particular to a kind of automobile seat massage function detection equipment. BACKGROUND

[0002] The massage function of automobile seat is mainly realized by two kinds of technologies: 1. massage motor system: install multiple small motors inside the seat, each motor drives eccentric wheel or cam, and vibration and pressing effect is generated by the rotation of motor;2. massage air bag system: multiple air bags are built-in the seat, and different pressure massage effect is formed by air pump control inflation and deflation.

[0003] The existing automobile seat massage function detection mainly has three detection methods: 1. by current detection: directly detect the current change of motor or air pump, to judge whether massage motor or air pump works normally. The disadvantage of this method is that the size of current can only judge the state of motor or air pump, if the massage mechanism driven by motor has a problem, or the air bag controlled by air pump is damaged, resulting in massage function failure, which cannot be detected. 2. by conventional pressure sensor detection: press the pressure sensor on each point of seat air pump or motor action position, to judge whether massage function is normal by the pressure change of each pressure sensor. This method can solve the pain points of current detection method, but it is one-to-one (one pressure sensor corresponds to one motor or air bag), if the seat massage position point on the same production line is different, there will be great limitation. 3. by seat surface deformation judgment: generally measure whether the seat surface is bulging by laser ranging sensor, to judge whether massage function is normal;This method is the same as pressure sensor detection method, and is limited by one-to-one method, and this method is simpler than pressure sensor method, but is more easily affected by seat foaming (if the seat foaming is hard, the action of adjacent motor or air bag will cause the deformation change of entire seat surface, thereby causing misjudgment).

[0004] In the above detection method, the most commonly used detection method is conventional pressure sensor detection, but this detection method cannot cope with various massage position seat types. UTILITY MODEL CONTENT
