Description

Technical Field

[0001] The present invention relates to an automobile washing system, and particularly to a vibration and noise damping type automobile washing system.

Background Art

[0002] With the continuous development and progress of the automobile industry, driving assistance and intelligent driving technologies have gradually begun to be applied, and the number of cameras, sensors, and lidars installed outside the vehicle body is increasing more and more. Since these devices attached to the outside of the vehicle body are exposed, when small flying insects, dust, mud, ice and snow adhere, it will affect the sensing ability of the device and reduce the accuracy of data collection. In the case of driving assistance vehicles or autonomous driving vehicles during driving, if these devices are dirty and the dirt cannot be quickly detected and cleaned, the accuracy of the collected data will be reduced, which will affect the control of the vehicle. In serious cases, the safety of driving will be endangered.

[0003] In the washing system, in order to obtain a washing effect, it is necessary to inject the washing liquid from the nozzle at high pressure and large flow rate. Therefore, the washing pump needs to rotate at high speed to supply power. The vibration generated by the high-speed rotating washing pump is transmitted to the washing liquid tank, amplified by the washing liquid tank, causing greater vibration and noise, which directly affects the comfort of the driver and passengers and is unacceptable. Therefore, it is urgently necessary to design a vibration and noise damping type automobile washing system in order to suppress vibration and reduce noise, thereby meeting the requirements of vehicle comfort.

[0009] More preferably, the elastic positioning column is provided with an axial opening groove. In this way, the positioning column is subjected to pressure between the opening grooves and moves inward, becoming radially elastic, which makes it easier to attach the positioning sleeve to the positioning column and also easier to attach the positioning sleeve to the limiting plate, further improving ease of assembly.

[0010] More preferably, the elastic positioning column has a circular hole in its center. This ensures that the positioning column has a uniform wall thickness, improved moldability, and avoids shrinkage deformation.

In this embodiment, they are arc-shaped engaging parts 104. The positioning sleeve 30 is mounted from the engaging port 105 into the engaging groove 108 of the limiting plate 101 and is restricted in the radial direction by the arc-shaped engaging parts 104. Also, the bottom surface of the limiting plate 101 restricts the positioning sleeve 30 in the axial direction by pressing the edge of the bottom of the positioning sleeve 30, thereby restricting the cleaning pump 20 and avoiding loosening of the cleaning pump 20.

[0022] A vibration damping groove 103 is further provided between the adjacent arc-shaped engaging parts 104 described above, and the side of the vibration damping groove 103 does not contact the outer circumference 301 of the positioning sleeve. In this way, the vibration and noise damping effect of the positioning sleeve 30 can be made better.

[0023] Relief grooves 107 are provided on each side of the engaging port 105 described above. In this way, it becomes easier for the positioning sleeve 30 to be inserted from the engaging port, and the positioning sleeve 30 quickly resets after being inserted into the engaging port 105, thereby fixing the positioning sleeve 30 more reliably.

[0024] A transition arc 102 is provided in the engagement opening 105 of the limiting plate 101, and the casing 301 of the positioning sleeve 30 can be easily engaged along the transition arc 102, thereby facilitating the assembly of the positioning sleeve 30 into the limiting plate 101 and improving ease of assembly.

[0031] When the positioning sleeve 30 is engaged with the engagement groove of the limiting member, the outer circular surface 301 is locked by a plurality of arc-shaped engaging portions 104, the mounting surface 303 of the edge 307 is in close contact with the end cover surface 207 of the cleaning pump 20, and the positioning surface 302 is restricted by the bottom surface of the limiting plate 101, thereby fixing and restricting the cleaning pump 20.

[0032] The seal ring 40 described above is made of an elastic material, and its upper end surface 401 is configured as a fixed surface, axially positioning the bottom surface 202 of the pump cover located on one side of the liquid supply nozzle 201 provided on the cleaning pump 20.

[0041] Similarly, the limiting plate of the cleaning fluid tank may be provided with an engagement groove (not shown) that matches such a positioning sleeve, thereby the limiting plate restricts the outer circumference 20021 of the positioning sleeve 2002 through the engagement groove, and the elliptical cylindrical edge 20023 is restricted by the bottom surface of the limiting plate, thereby fixing and restricting the cleaning pump 20, and thus also providing vibration damping and noise damping effects.

[0042] The positioning column 20011 is further provided with a vertical opening groove 20012, which gives the positioning column 20011 elasticity in the radial direction, making it easier to attach the positioning sleeve 2002 to the positioning column 20024, and also easier to attach the positioning sleeve 2002 inside the limiting plate, thereby improving ease of assembly.

[0043] An elliptical hole 20013 is further provided in the center of the positioning column 20024. This ensures that the positioning column 20024 has a uniform wall thickness, improved moldability, and avoids shrinkage deformation.
