Description

TECHNICAL FIELD

The present disclosure relates to the technical field of car washing machines, and in particular, to a skirt brush mechanism with a novel structure.

DESCRIPTION OF RELATED ART

With the rapid development of China's economy, the automobile industry has developed rapidly, and cars have become the main means of transportation for people's daily travel. China's car ownership is huge, which drives economic development of related fields, such as cleaning of cars. Emergence of current unmanned fully automatic car washing machines can well solve shortcomings of high labor intensity, low efficiency, high labor costs, and high car washing costs existing in conventional manual cleaning with water guns.

As shown in FIG. 3, an existing skirt brush mechanism of a car washing machine is usually fixed by a skirt brush bracket composed of a column and a bottom plate, where the bottom plate is fixed on a cement floor through expansion bolts, and a cylinder drives a swing arm to swing, so as to implement swinging brushing of a skirt brush. Due to frequent action of the cylinder, the expansion bolts are prone to being loosened over time. In addition, the large-sized column bracket consumes a lot of materials and labor, resulting in high cost.

Therefore, there is an urgent need for a skirt brush mechanism with a novel structure, which simplifies a bracket structure, avoids bolt loosening, and reduces costs.

SUMMARY OF THE PRESENT DISCLOSURE

An objective of the present disclosure is to provide a skirt brush mechanism with a novel structure in response to the above problems existing in the prior art.

In order to achieve the above objective, the present disclosure employs the following technical solution: A skirt brush mechanism with a novel structure includes:

• • a skirt brush, vertically arranged for brushing side surfaces of a vehicle;
  • a swing arm with one end connected to a top of the skirt brush and the other end connected to a fixed connection bracket, and capable of rotating horizontally on the fixed connection bracket;
  • a reduction motor, arranged on the swing arm and in driving connection with the top of the skirt brush to drive the skirt brush to rotate for brushing;
  • the fixed connection bracket, fixed on an automatic car washing machine and suspended;
  • an oblique fixed arm, arranged on one side of the fixed connection bracket and used for mounting a stretching actuator; and
  • the stretching actuator with one end rotatably connected to the oblique fixed arm and the other end rotatably connected to the swing arm to drive the swing arm to swing back and forth on the fixed connection bracket.

Working principle and beneficial effects are as follows: 1. Compared with the prior art, the skirt brush of the present disclosure can be fixed on the automatic car washing machine through the fixed connection bracket, and the fixed connection bracket is no longer connected to the cement floor through expansion bolts, so even if the stretching actuator is used frequently, the expansion bolts will not be loosened; a large-sized column bracket is also not required, which can significantly reduce mounting time and cost; and

2. Compared with the prior art, the swing arm of the present disclosure is rotatably connected to the fixed connection bracket, does not need to be mounted through a vertical seat bearing as before, but can be mounted through a rotating shaft, which will not produce an open structure to affect its aesthetics.

Further, a positioning block is arranged on the fixed connection bracket, and the positioning block limits a rotation stroke of the swing arm. In this case, the rotation stroke of the swing arm can be limited by the positioning block, so that the stretching actuator can no longer work at a full stroke every time, which significantly prolongs the service life of the stretching actuator.

Further, the stretching actuator is rotatably connected to a middle segment of the swing arm. The swing arm is conveniently driven to swing.

Further, the fixed connection bracket is rotatably connected to the swing arm through a rotating shaft and a rolling bearing. A conventional vertical seat bearing is replaced, so the structure is more compact and attractive. In addition, the rolling bearing is equivalent to the vertical seat bearing mounted inside, so the structure is relatively hidden, added grease will not be lost due to the impact of high-pressure water thereon, and the appearance is attractive.

Further, the positioning block is provided with a gap, a portion of the swing arm is located inside the gap, and the gap limits the rotation stroke of the swing arm. The stroke is limited by the gap, with a simple structure and low implementation difficulty.

Further, the reduction motor is connected to the rotating shaft through a key slot, and the rotating shaft is connected to the skirt brush through a flange.

Further, the stretching actuator is an air cylinder or an electric cylinder. The air cylinder has the advantages of simple structure and convenient maintenance, is cheaper than the electric cylinder, has high wear resistance, and can operate for a long time. The electric cylinder has fast action, stable power, and high control accuracy, is very convenient to maintain, does not require frequent maintenance, and has a low failure rate. The selection of the air cylinder or the electric cylinder should be considered according to a specific application situation. If high efficiency and fine control are required, the electric cylinder is more suitable. If the requirements are simple and the cost is low, the air cylinder is more suitable.
