Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle washing technology, in particular to a tunnel type automatic car washing machine. BACKGROUND

[0002] The existing full-automatic computer car washing equipment adopts profiled brush washing. The so-called profiled brush washing is to control the adhesion degree of the rotating top brush bristles through touch pressure control technology to perform brush washing operation on the vehicle outer surface. The movement track of the top brush is generated through repeated correction of the vehicle outer surface. Especially for vehicle models with complex body contours, the working efficiency is low. In addition, due to the complexity of vehicle models and the large difference in vehicle appearance contour size, the traditional mechanical brush cannot quickly change the distance between the cleaning brushes. In the cleaning process, the two side brushes and the upper brush are easily pressed against large-size vehicles to cause brush marks on the vehicle surface. At the same time, it is difficult to form a large cleaning force for small-size vehicles, and often there are parts that cannot be cleaned. In addition, when facing the upper cleaning, the fixed downward washing is usually used, which is easy to cause pressure on the top of the vehicle. At the same time, when facing the cleaning of some dirty parts of the vehicle body, it cannot realize local cleaning, causing waste of energy efficiency and increase of cleaning time. SUMMARY
