Description

[Technical Field]

[0001] The present invention relates to a car wash system, and more particularly to a vibration and noise damping car wash system. [Background technology]

[0002] As the automotive industry continues to develop and advance, driver assistance and intelligent driving technologies are gradually being adopted, leading to an increasing number of cameras, sensors, and lidars being installed on the exterior of vehicles. Because these devices are mounted on the exterior of the vehicle, they are exposed to the outside, and contamination by small flying insects, dust, mud, ice, snow, etc. can affect the sensing capabilities of the devices and reduce the accuracy of data collection. For driver assistance and autonomous vehicles, if these devices become dirty while in operation and the contamination is not detected and cleaned promptly, the accuracy of collected data will be reduced, affecting vehicle control and, in serious cases, posing a risk to driving safety.

[0003] To achieve a cleaning effect, the cleaning system needs to spray the cleaning fluid from the nozzle at high pressure and with a large flow rate, so the cleaning pump needs to rotate at a high speed to provide power. The vibrations generated by the high-speed rotating cleaning pump are transmitted to the cleaning fluid tank and further amplified by the tank, causing greater vibration and noise, which is unacceptable as it directly affects the comfort of the driver and passengers. Therefore, there is an urgent need to design a vibration- and noise-damping car washing system that can suppress vibration and reduce noise, thereby meeting the requirements for vehicle comfort.

[0021] A limiting plate 101 is provided on the side wall of the cleaning liquid tank 10, facing the mounting hole 106 (liquid outlet), and is provided with an engagement groove 108, which includes an engagement port 105 and a plurality of engagement portions that fit with the outer periphery of the positioning sleeve, which in this embodiment are arc-shaped engagement portions 104. The positioning sleeve 30 is attached to the engagement groove 108 of the limiting plate 101 through the engagement port 105 and is restricted in the radial direction by the arc-shaped engagement portions 104, and the bottom surface of the limiting plate 101 presses against the edge of the bottom of the positioning sleeve 30, thereby restricting the positioning sleeve 30 in the axial direction, thereby restricting the cleaning pump 20 and preventing the cleaning pump 20 from loosening.

[0022] A vibration-damping groove 103 is further provided between the adjacent arc-shaped engagement portions 104, and the sides of the vibration-damping groove 103 do not contact the outer periphery 301 of the positioning sleeve. In this way, the vibration and noise damping effect of the positioning sleeve 30 can be improved.

[0023] An escape groove 107 is provided on each side of the engagement opening 105. In this way, the positioning sleeve 30 can be easily inserted into the engagement opening, and the positioning sleeve 30 can quickly return to its original position after being inserted into the engagement opening 105, thereby more reliably fixing the positioning sleeve 30.

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

[0025] A positioning pillar 206 is provided on the end cover surface 207 of the above-mentioned cleaning pump 20. In this embodiment, the positioning pillar 206 is a cylindrical body that fits into the positioning hole 305 of the positioning sleeve 30, and the positioning sleeve 30 is placed over the positioning pillar 206 through the positioning hole 305 and fixed.

The positioning sleeve body between the circumference of the cylindrical positioning hole 305 and the outer circular surface 301 has a plurality of vibration-damping holes 306 equally spaced circumferentially, and an annular edge 307 at the bottom of the positioning sleeve 30.

[0030] A transition arc surface 304 is provided at the opening of the positioning hole 305, so that the positioning sleeve 30 can be easily fitted into the positioning post 206.

[0031] When the above-mentioned positioning sleeve 30 is inserted into the engagement groove of the restricting member, the outer circular surface 301 is engaged by the multiple arc-shaped engagement portions 104, the mounting surface 303 of the edge portion 307 is in close contact with the end cover surface 207 of the cleaning pump 20, and the positioning surface 302 is limited by the bottom surface of the restricting plate 101, thereby fixing and restricting the cleaning pump 20.

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

[0033] A seal hole 405 is provided in the center of the seal ring 40, by which the liquid supply nozzle 201 provided on the washing pump 20 is sealed and fixed.

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

[0043] An elliptical hole 20013 is further provided at the center of the positioning post 20024, thereby making the positioning post 20024 have a uniform wall thickness, good formability, and avoid shrinkage degeneration.

[0044] Figure 12 shows a further embodiment of a positioning pillar and positioning sleeve, in which the positioning sleeve 3002 is designed square and has a T-shaped hole 30022 inside, vibration damping holes 30021 spaced apart on the outside of the T-shaped hole 30022, and a square edge 30023 at the bottom, and the end cover surface 30011 of the cleaning pump 3001 is provided with a T-shaped pillar 30012 for attaching the positioning sleeve 3002, the T-shaped hole 30022 fits snugly into the T-shaped pillar 30012, and the positioning sleeve 3002 is tightly fixed to the T-shaped pillar 30012.
