DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As shown in Figures 1-7 , the present application provides a cleaning system for cleaning data acquisition components (such as cameras, radars, etc.) on a vehicle, which includes washing kettles 1, intermediate connectors 2, water pumps 4 and cleaning pipelines 6. The washing kettles 1 are used to hold washing liquid, and multiple washing kettles 1 are provided and installed at different positions on the vehicle, for example, two, three or four washing kettles 1 are provided, and the washing kettles 1 are fixedly installed with the frame of the vehicle. The intermediate connectors 2 are respectively connected to the multiple washing kettles 1 to make the multiple washing kettles 1 communicate with each other, so that the liquid levels of the washing liquid in the multiple washing kettles 1 can be kept balanced. In addition, the intermediate connectors 2 are arranged between the multiple washing kettles 1, for example, when two washing kettles 1 are provided, the intermediate connector 2 is arranged between the connecting lines of the two washing kettles 1, when three washing kettles 1 are provided, the intermediate connector 2 is arranged inside the triangle formed by the three washing kettles 1, and when four or more washing kettles 1 are provided, the intermediate connector 2 is arranged inside the polygon formed by the multiple washing kettles 1.

[0028] The inlet of the water pump 4 is communicated with the intermediate connector 2, and the outlet of the water pump 4 is communicated with the cleaning pipeline 6. Under the action of the water pump 4, the washing liquid in the washing kettle 1 flows through the intermediate connector 2, the water pump 4 and the cleaning pipeline 6 in turn, and is sprayed out by the spray head on the cleaning pipeline 6, so as to realize the cleaning of the data acquisition component. The water pump 4 can be provided with one or multiple. When the water pump 4 is provided with multiple, the multiple water pumps 4 can be connected in parallel, that is, the inlet of each water pump 4 is communicated with the intermediate connector 2, and the outlet of each water pump 4 is communicated with the cleaning pipeline 6. Here, the number of water pumps 4 is preferably one, which can simplify the structure of the cleaning system.

[0029] When the vehicle runs on a slope, the multiple washing kettles 1 tilt with the vehicle, although the washing liquid in the higher washing kettle 1 will flow into the lower washing kettle 1 through the intermediate connector 2, but since the intermediate connector 2 is located between the multiple washing kettles 1, the water pump 4 is communicated with the intermediate connector 2, and under the action of the water pump 4, the washing liquid in at least one washing kettle 1 can flow through the intermediate connector 2 to the cleaning pipeline 6, to complete the cleaning of the data acquisition component, thereby solving the problem of cleaning failure caused by the inclination of the vehicle.

[0030] It can be understood that the intermediate connector 2 has a chamber for converging the washing liquid, which is communicated with the multiple washing kettles 1 and the water pump 4 respectively, and the washing liquid can flow to the water pump 4 after converging in the chamber, for example, the intermediate connector 2 is provided as a tubular hollow structure.

[0031] In the specific scheme, the intermediate connector 2 is communicated with the bottom of the washing kettle 1 through a water pipe, so that the washing liquid at the bottom of the washing kettle 1 can be discharged through the intermediate connector 2. Moreover, the height of the intermediate connector 2 does not exceed the height of the bottom of the washing kettle 1, so that the water pipe between the intermediate connector 2 and the washing kettle 1 can be prevented from storing washing liquid, when it is needed to empty the washing liquid, the washing liquid in the washing kettle 1 can be completely discharged through the intermediate connector 2, and when the vehicle is inclined, the intermediate connector 2 can be placed at a lower position, which is beneficial to the discharge of the washing liquid through the intermediate connector 2.

[0032] In the scheme, the water pump 4 is arranged between the multiple washing kettles 1, for example, when the washing kettle 1 is provided with two, the water pump 4 is arranged between the connecting line of the two washing kettles 1, when the washing kettle 1 is provided with three, the water pump 4 is arranged in the triangle surrounded by the three washing kettles 1, and when the washing kettle 1 is provided with four or more, the water pump 4 is arranged in the polygon surrounded by the multiple washing kettles 1.

[0033] A filter 3 is arranged between the intermediate connector 2 and the water pump 4, so that the inlet of the water pump 4 communicates with the intermediate connector 2 through the filter 3, that is, the filter 3 is arranged at an upstream position of the water pump 4. During cleaning, the washing liquid in the washing kettle 1 first flows through the filter 3 and then flows through the water pump 4. The filter 3 can filter out impurities in the washing liquid to avoid affecting the stable operation of the water pump 4, thereby improving the stability and service life of the system.

[0034] As shown in Figures 1-3 The vehicle frame is provided with a bearing bracket 8, and the intermediate connector 2, the filter 3 and the water pump 4 are all mounted on the bearing bracket 8. The filter 3 and the water pump 4 are respectively connected to the two end portions of the bearing bracket 8, and the filter 3 and the water pump 4 are located on the same side of the intermediate connector 2. Such a layout is beneficial to improve the balance of the mounting structure.

[0035] In order to improve the cleaning pressure, the water pump 4 is designed as a high-pressure pump. The pressure range of the water pump 4 is 9-16 bar, and 11 bar is preferred. Compared with the 2 bar pump used in the prior art, the design of the high-pressure pump can improve the water pressure of the spray cleaning, which is beneficial to improve the cleaning degree of the data acquisition component. At the same time, since the intermediate connector 2, the filter 3 and the connecting pipe are arranged between the water pump 4 and the washing kettle 1, the connecting path is relatively long. By setting the water pump 4 as a high-pressure pump, the water pressure inside the pipeline of the cleaning system can be improved, and the timeliness and accuracy of cleaning the data acquisition component can be ensured.

[0036] It should be noted that by setting the water pump 4 as a high-pressure pump, the number of water pumps 4 can also be set to one. Only one water pump 4 is needed to have a good cleaning pressure in the cleaning pipeline 6. Compared with the multiple pump scheme in the prior art, the structure is simplified. In addition, in other schemes, in order to improve the cleaning pressure, the water pump 4 can also be designed as multiple, that is, multiple water pumps 4 are used to suck the washing liquid in the washing kettle 1, which can achieve the corresponding effect.

[0037] In some embodiments, the outlet of the water pump 4 communicates with the cleaning pipeline 6 through a tee joint 5. The tee joint 5 has a first interface, a second interface and a third interface. For example, the first interface is a side port, and the second interface and the third interface are straight ports. The first interface of the tee joint 5 communicates with the outlet of the water pump 4, the second interface of the tee joint 5 communicates with the cleaning pipeline 6, and the third interface of the tee joint 5 communicates with the intermediate connector 2 or the washing kettle 1 through a gas return pipe. The gas return pipe or the end joint of the gas return pipe is provided with a gas return hole 10, that is, the gas return hole 10 can be arranged at the middle position of the gas return pipe or at the end position of the gas return pipe.

[0038] In the specific design, the cleaning pipeline 6 has a surrounding pipeline and a connecting pipeline. The surrounding pipeline encircles the vehicle and extends to the locations of various data acquisition components. The connecting pipeline connects the second interface of the tee connector 5 to the surrounding pipeline, and a one-way valve 7 is installed on the connecting pipeline to prevent detergent backflow within the surrounding pipeline. In actual use, the interior of the system pipeline (especially the section between the outlet of the water pump 4 and the one-way valve 7) contains not only detergent liquid but also residual air. This air forms bubbles during system operation, affecting the flow of detergent liquid, leading to unstable system pressure, and even generating noise and vibration.

[0039] When the water pump 4 is first started, pressure accumulates in the pipeline between the outlet of the water pump 4 and the one-way valve 7. Under the action of the air return hole 10, the air in the pipeline between the outlet of the water pump 4 and the one-way valve 7 is discharged through the air return pipe to the intermediate connector 2 or the washing pot 1, thereby reducing the air bubbles in the cleaning pipeline 6, reducing the noise and vibration of the system operation, and ensuring the stability of the system.

[0040] It should be noted that the return air pipe can be connected to the intermediate connector 2 or to the washing pot 1. Here, it only needs to be connected to the component upstream of the water pump 4.

[0041] Specifically, the diameter of the return air hole 10 is set to 0.35-0.45 mm, preferably 0.4 mm. In this way, by designing the diameter of the return air hole 10, it can be made to allow gas to pass through but not water, thereby preventing the washing liquid downstream of the water pump 4 from flowing back to the upstream of the water pump 4.

[0042] like Figures 4-6 As shown, the third interface of the tee connector 5 is connected to a return air connector 9, which connects to both the third interface and the return air pipe. For example, the return air connector 9 can be cylindrical, with one end of the return air pipe connected to the inside of the third interface via a threaded structure, and the other end connected to the intermediate connector 2 via a water pipe. A return air hole 10 is provided on the central axis of the return air connector 9, connecting the tee connector 5 and the intermediate connector 2. Thus, the return air hole 10 has a simple structure, is easy to manufacture, and the tee connector 5 can utilize its existing structure, assembling with the return air connector 9, which helps save costs and reduces manufacturing and design complexity.

[0043] In some embodiments, the water pump 4 is configured as a high-pressure pump, the cleaning pipeline 6 is configured as a high-pressure pipe, and multiple nozzles are respectively arranged at multiple different positions on the high-pressure pipe. For example, the high-pressure pipe has an annular portion, on which multiple nozzles are arranged in sequence, so that the multiple nozzles are respectively close to multiple data acquisition components on the vehicle, so as to clean the multiple data acquisition components respectively.

[0044] The high-pressure pipe comprises, from inside to outside, a PP material layer 11, a TIE material layer 12, and a PA12 material layer 13. The TIE material layer 12 is arranged around the outer periphery of the PP material layer 11, and the PA12 material layer 13 is arranged around the outer periphery of the TIE material layer 12. PP (Polypropylene) is a lightweight, chemical corrosion-resistant, and heat-resistant plastic material. It is made of propylene monomers through polyaddition reaction and is a semi-crystalline thermoplastic polymer. It has high heat resistance, chemical resistance, and mechanical strength and toughness. TIE (Textile Interior Elements) is a material commonly used in automotive interiors, which usually includes fabrics, leather, plastics, and other materials. PA12 (Polyamide 12) is a nylon material with the chemical name polydodecanamide. It has high heat resistance and mechanical properties, is soft and resistant to high pressure. In this scheme, the combination of the PP material layer 11, the TIE material layer 12, and the PA12 material layer 13 can make the high-pressure pipe have good heat resistance and high-pressure resistance, which is beneficial to improve the service life of the cleaning pipeline 6.

[0045] The vehicle provided by the embodiment of the present application comprises the cleaning system in the above embodiment. In this way, when the vehicle is running on a slope, the intermediate connector 2 is located between the plurality of washing pots 1, the water pump 4 is in communication with the intermediate connector 2, and under the action of the water pump 4, the washing liquid in at least one washing pot 1 can flow to the cleaning pipeline 6 through the intermediate connector 2 to complete the cleaning of the data acquisition component, thereby solving the problem of cleaning failure caused by the inclination of the vehicle.
