[0033] See also Figures 1 to 3 Now, a rear camera 300 cleaning device provided by the utility model is described. A rear camera 300 cleaning device includes a washing nozzle 200 and a washing pipeline 100.

[0034] The washing nozzle 200 is installed on the camera bracket 400 in the inner compartment of the tailgate, and the spray direction of the washing nozzle 200 is set toward the direction of the rear camera 300; the cleaning pipe 100 is arranged along the direction of the tailgate wiring harness, and the liquid inlet end 110 of the cleaning pipe 100 is connected to the rear air curtain washing pipe 140, and the liquid outlet end 120 of the cleaning pipe 100 passes through the tailgate sheet metal and enters the inner compartment of the tailgate to connect with the washing nozzle 200.

[0035] The utility model provides a cleaning device for a rear camera 300. Compared with the prior art, a washing nozzle 200 is installed on a camera bracket 400 in the inner compartment of a rear door, and the spray direction of the washing nozzle 200 is set toward the rear camera 300. The washing pipeline 100 is arranged along the direction of the rear door harness, and the washing pipeline 100 has a liquid inlet end 110 and a liquid outlet end 120. The liquid inlet end 110 of the washing pipeline 100 is connected to the rear air curtain washing pipeline 140, and the washing pipeline 100 shares the cleaning liquid of the air curtain washing pipeline. The liquid outlet end 120 of the washing pipeline 100 passes through the rear door from the inside to the outside and penetrates into the inner compartment of the rear door, and the liquid outlet end 120 of the washing pipeline 100 is connected to the liquid inlet of the washing nozzle 200. When using the rear camera 300 cleaning device provided by the utility model, the cleaning liquid enters the liquid inlet end 110 of the cleaning pipeline 100 through the rear air curtain cleaning pipeline 140, and the cleaning liquid enters the cleaning nozzle from the liquid outlet end 120 through the cleaning pipeline 100. The cleaning liquid is sprayed on the rear camera 300 through the washing nozzle to clean the rear camera 300. There is no need for the driver to get off the vehicle for manual cleaning, and the operation is convenient.

[0036] See also Figure 1 The cleaning device of the rear camera 300 also includes a three-way pipe 130 .

[0037] Specifically, the three-way pipe 130 is arranged on the rear air curtain washing pipeline 140, and the liquid inlet end 110 of the cleaning pipeline 100 is connected to the rear air curtain washing pipeline 140 through the three-way pipe 130. The three-way pipe 130 has a liquid inlet pipe and two liquid outlet pipes. The liquid inlet pipe of the three-way pipe 130 is connected to the vehicle-mounted water tank through a connecting pipe, and the two liquid outlet pipes are respectively connected to the rear air curtain washing pipeline 140 and the cleaning pipeline 100. The vehicle-mounted water tank can provide cleaning liquid to the rear air curtain washing pipeline 140 and the cleaning pipeline 100 respectively through the three-way pipe 130.

[0038] The three-way pipe 130 may be a conventional pipe, and the cleaning fluid enters the rear wind curtain washing pipeline 140 and the cleaning pipeline 100 through the three-way pipe 130 at the same time, and cleans the rear windshield and the rear camera 300 at the same time.

[0039] In addition, the three-way pipe 130 can also be an electromagnetic three-way valve (electromagnetic three-way), which is electrically connected to the on-board computer. The driver can control the on-off state of the electromagnetic three-way valve through the on-board computer in the car, so that the rear air curtain washing pipeline 140 can be provided with cleaning fluid separately to clean the rear windshield, and the cleaning pipeline 100 can be provided with cleaning fluid separately to clean the rear camera 300. Similarly, the rear air curtain washing pipeline 140 and the cleaning pipeline 100 can also be opened at the same time to achieve the effect of cleaning the rear windshield and the rear camera 300 at the same time.

[0040] See also Figure 3 The cleaning device of the rear camera 300 also includes a one-way valve 150 .

[0041] Specifically, the one-way valve 150 is disposed at the liquid outlet 120 of the cleaning pipeline 100, and the one-way valve 150 is used to guide the cleaning liquid in the cleaning pipeline 100 to flow in a one-way direction toward the cleaning nozzle 200. The one-way valve 150 can prevent the cleaning liquid from flowing back in the opposite direction, and prevent the cleaning liquid mixed with debris flowing back in the opposite direction from entering the cleaning pipeline 100, resulting in blockage of the cleaning pipeline 100. At the same time, the one-way valve 150 can also be used to adjust the flow rate of the cleaning liquid provided by the liquid outlet 120 of the cleaning pipeline 100 to the cleaning nozzle 200, thereby controlling the flow rate and flow rate of the cleaning liquid sprayed outward by the cleaning nozzle 200. Different flow rates and flows can be selected according to different degrees of contamination of the rear camera 300, so as to achieve both water saving and the best cleaning state.

[0042] See also Figure 3 The Z-direction height of the one-way valve 150 is lower than the Z-direction height of the rear camera 300 , and a clearance angle 410 for avoiding the one-way valve 150 is provided at the lower side of the camera bracket 400 .

[0043] Specifically, the Z-direction height of the one-way valve 150 is lower than the Z-direction height of the rear camera 300, so that the liquid inlet end 110 of the cleaning pipeline 100 can be set in the lower area of ​​the camera bracket 400. By setting a clearance angle 410 below one side of the camera bracket 400, the space utilization rate of the lower area of ​​the camera bracket 400 can be improved, and the overall integration is higher. That is, the one-way valve 150 is located at the lower side of the rear camera 300. In order to avoid interference with the camera bracket 400 on which the rear camera 300 is installed when the one-way valve 150 is installed, a clearance angle 410 is set below one side of the camera bracket 400, and the clearance angle 410 can avoid the one-way valve 150. At the same time, in order to further avoid the liquid inlet end 110 of the cleaning pipeline 100, an avoidance channel is also provided on one side of the lower part of the camera bracket 400 close to the avoidance angle 410. The avoidance channel is connected to the above-mentioned avoidance angle 410 and can avoid the liquid inlet end 110 of the cleaning pipeline 100, thereby allowing the liquid inlet end 110 of the cleaning pipeline 100 with a one-way valve 150 to be installed smoothly.

[0044] See also Figure 4 The middle part of the camera bracket 400 is protruded outward, and the end surface of the protruding structure forms an assembly area 420. The rear camera 300 and the washing nozzle 200 are installed in the assembly area 420 with a horizontal interval. Specifically, the washing nozzle 200 is located in the upper left area of ​​the rear camera 300, and the distance between the axis of the washing nozzle 200 and the axis of the rear camera 300 is 15mm-20mm.

[0045] The outer end surfaces on both sides of the assembly area 420 are lower than the assembly area 420 of the protruding structure. The outer end surfaces on both sides of the assembly area 420 are respectively provided with first reinforcing ribs 430. The first reinforcing ribs 430 have a plurality of structures, which have an annular arrangement structure, a longitudinal arrangement structure, and a transverse arrangement structure. The first reinforcing ribs 430 of the above-mentioned different structures are combined and arranged in different ways, which can greatly increase the structural strength of the camera bracket 400 itself. Preferably, the first reinforcing ribs 430 arranged on both sides of the assembly area 420 have at least one annular arrangement reinforcing rib structure, and the annular arrangement first reinforcing rib 430 is displaced in the middle, and the other longitudinal and transverse arrangement first reinforcing ribs 430 are located outside the above-mentioned annular structure.

[0046] See also Figure 3 The rear camera 300 cleaning device also includes an anti-vibration layer 160 .

[0047] The vibration-proof layer 160 is wrapped around the outer circumference of the cleaning pipeline 100 . The vibration-proof layer 160 forms a cylindrical structure, and the material may be foam material.

[0048] The vibration-proof layer 160 is located on the side of the washing pipe 100 close to the washing nozzle 200. When the washing nozzle 200 sprays cleaning fluid toward the rear camera 300, the washing nozzle 200 will vibrate. By arranging the vibration-proof layer 160 on the side of the washing pipe 100 close to the washing nozzle 200, the vibration of the washing pipe 100 close to the washing nozzle 200 can be reduced, and abnormal sounds of the washing pipe 100 in the working state can be reduced.

[0049] See also Figure 2 , Figure 3 as well as Figure 4 , a mounting hole 440 is provided on the camera bracket 400, and the shape of the mounting hole 440 is adapted to the outer contour of the area where the washing nozzle 200 is to be installed. For a conventional washing nozzle 200, two elastic fins are symmetrically arranged at the front of the washing nozzle 200 or a plurality of elastic fins are distributed circumferentially. The elastic fins are inclined outward from front to back and have a certain resilience. An annular edge is integrally arranged in the circumference of the middle part of the washing nozzle 200. The circumference of the mounting hole 440 is provided with a clamping structure 441 for clamping the washing nozzle 200. The clamping structure 441 is a protrusion or annular edge integrally formed on the outer end surface of the camera bracket 400. When installing the washing nozzle 200, the washing nozzle 200 passes through the mounting hole 440 from the inside to the outside, and the elastic fins at the front of the washing nozzle 200 are squeezed by the edge of the mounting hole 440 until the elastic fin part of the washing nozzle 200 passes through the mounting hole 440, and then the elastic fins rebound. At this time, the annular edge abuts against the inner side of the camera bracket 400 , and the end of the elastic fin abuts against the protrusion or the annular edge, so that the washing nozzle 200 is stably installed on the camera bracket 400 .

[0050] See also Figure 2 , a rear license plate light bracket 500 is disposed outside the camera bracket 400, and the rear end surface of the rear license plate light bracket 500 is used to install the vehicle license plate. A through hole is provided in the rear license plate light bracket 500 corresponding to the end of the rear camera 300, and the end of the rear camera 300 passes through the through hole, so that its shooting end protrudes from the rear license plate light bracket 500 to shoot the image behind the vehicle. Similarly, a avoidance hole 510 is provided on the rear license plate light bracket 500, and the avoidance hole 510 corresponds to the position of the washing nozzle 200. The end of the washing nozzle 200 passes through the avoidance hole 510 and protrudes from the rear license plate light bracket 500. The direction in which the washing fluid is sprayed from the end of the washing nozzle 200 is toward the shooting end of the end of the rear camera 300, so as to facilitate cleaning of the shooting end of the end of the rear camera 300.

[0051] See also Figure 5 , the inner side surface of the rear license plate light bracket 500 is provided with a second reinforcing rib 520, and the second reinforcing rib 520 is arranged in the circumference of the avoidance hole 510. Similarly, the second reinforcing rib 520 also has a plurality of ribs, which have a ring-arranged structure, a longitudinally arranged structure, and a transversely arranged structure. The second reinforcing ribs 520 of different structures are combined and arranged in different ways, which can greatly increase the structural strength of the rear license plate light bracket 500 itself. Preferably, the second reinforcing rib 520 has at least one ring-arranged reinforcing rib structure, and the ring-arranged second reinforcing rib 520 is displaced in the middle and surrounded in the circumference of the avoidance hole 510. The longitudinally and transversely arranged second reinforcing ribs 520 are grouped in pairs to form a "T"-shaped structure and are located on the periphery of the ring-arranged reinforcing rib structure, which can greatly improve the structural strength of the rear license plate light bracket 500 itself.

[0052] Based on the same inventive concept, the utility model also provides a vehicle, which uses the above-mentioned rear camera 300 cleaning device, and thus has the same beneficial effects as the rear camera 300 cleaning device. When the rear camera 300 cleaning device is used, the cleaning liquid enters the liquid inlet end 110 of the cleaning pipeline 100 through the rear air curtain washing pipeline 140, and the cleaning liquid enters the washing nozzle from the liquid outlet end 120 through the cleaning pipeline 100. The cleaning liquid is sprayed on the rear camera 300 through the washing nozzle to clean the rear camera 300, and the driver does not need to get off the vehicle to clean manually, which is convenient to operate.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
