Description

Technical Field

[0002] With the continuous development of autonomous driving technology, autonomous vehicles have gradually become part of our daily lives. For example, LiDAR sensors, as key components for autonomous vehicles to perceive the external environment, have a crucial impact on their safety. During operation, the sensor's sensing surface may be affected by the external environment, resulting in various deposits such as dust, mud, water, rain, and snow. These deposits can affect the sensor's sensing performance and accuracy.

[0003] Currently, sensors are typically equipped with cleaning devices to remove debris. Air purge technology is the predominant cleaning method used in the market. This method uses a cleaning device to spray high-speed air onto the sensor's sensing surface, using the impact of the airflow to blow debris off the sensing surface.

[0004] However, in the case where the sensor includes, for example, a laser radar, the area of its sensing surface may be large, and the air outlet of the cleaning device may have an uneven airflow distribution problem when spraying airflow, resulting in that attachments in some areas of the sensing surface are difficult to be effectively removed, prolonging the cleaning time, increasing energy consumption, reducing cleaning efficiency, and obtaining poor cleaning results, while other areas may be damaged due to excessive airflow, reducing the service life of the sensor.

[0060] The following describes the implementation and use of the embodiments in detail. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present application and are not intended to limit the scope of the present application. When describing the structural positions of various components, such as up, down, top, and bottom, directional expressions are not absolute but relative. These directional expressions are appropriate when the components are arranged as shown in the figures, but if the positions of the components in the figures are changed, these directional expressions will also change accordingly.

[0061] As used herein, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this document based on the specific circumstances.

[0062] Herein, “transverse direction” refers to a direction with a relatively smaller size, which may also be referred to as a width direction, and “longitudinal direction” refers to a direction with a relatively larger size, which may also be referred to as a length direction.

[0063] Autonomous vehicles include a variety of sensors to perceive the external environment. LiDAR, a key sensor, creates high-resolution three-dimensional maps of the environment by emitting laser beams and receiving reflected signals. However, dust, mud, water, or other debris on the sensing surface can scatter or absorb the laser beam, resulting in inaccurate measurement data. It has been recognized that when using air purge technology to clean LiDAR, uneven air flow and direction can lead to incomplete and inefficient cleaning, impacting LiDAR sensing accuracy.

[0064] In this article, driverless vehicles include but are not limited to driverless passenger cars, driverless delivery vehicles, driverless street sweepers, etc.

[0065] In an unmanned vehicle, in addition to using a laser radar to sense objects, a camera is usually used in conjunction with the laser radar to provide comprehensive perception capabilities. Since cameras have a low cost, multiple cameras are usually arranged in an unmanned vehicle to provide redundant and diverse sensing data. It is understandable that during the operation of the camera, a corresponding cleaning device is also required to clean the sensing surface of the camera. In this article, the cleaning device for cleaning the laser radar will be referred to as a cleaning device, and the cleaning device for cleaning the camera will be referred to as an additional cleaning device. In addition, it is understandable that this article only shows two sensors for sensing objects, namely, a laser radar and a camera. However, the unmanned vehicle can be equipped with other sensors for sensing objects and corresponding cleaning devices as needed, and this is not limited here.

[0066] Figure 1 A cleaning system according to an embodiment of the present application is shown, which is particularly suitable for cleaning laser radars and cameras. The cleaning system includes multiple supply pipes. Figure 1 Four supply lines are shown in FIG. 1 , each of which includes an air intake line, a radar air intake branch, and a camera air intake branch. The radar air intake branch is connected to a cleaning device, and the camera air intake branch is connected to an additional cleaning device. The cleaning device is provided on a surface of the laser radar 600 that can be installed, for example, Figure 3 The surface 620 shown, the additional cleaning device is provided on the surface of the camera 700 for installation, such as Figure 14 It is understood that the number of supply pipelines of the cleaning system can be changed according to needs and is not limited to that shown in the figure. In addition, the number of radar air intake branches and camera air intake branches of each supply pipeline can also be changed according to needs. For example, the supply pipeline can only include the radar air intake branch.

[0067] Combine Figure 1 and Figure 2As shown, the cleaning system also includes an air supply device 500, which is used to provide the cleaning fluid required for the cleaning process, in this case air. The air supply device 500 includes a housing 510 and a top cover 520 connected to the housing 510. The housing 510 is integrated with at least one fan 530 for air supply, and a control device 540 electrically connected to the fan 530. The control device 540 can be, for example, electrically connected to the ECU (electronic control unit) of the unmanned vehicle to regulate the air supply from the fan 530 to each cleaning device. Each fan 530 is connected to a respective supply pipeline to provide air to the cleaning device and additional cleaning device in the supply pipeline, thereby cleaning the lidar 600 and camera 700. The fan 530 is generally energy-efficient and can operate continuously without increasing excessive energy consumption. In this way, in situations where cleaning requires a long time due to continuous rain, for example, using the fan 530 for air supply can maintain a stable cleaning effect without frequent shutdown or energy replacement. It is understandable that the cleaning fluid is not limited to air. For example, liquid can also be used to clean the laser radar 600 and the camera 700. When the cleaning fluid is liquid, the air supply device 500 can be replaced by a liquid pump, for example.

[0068] In this embodiment, multiple fans 530 and control devices 540 are integrated in the housing 510 of the air supply device 500, realizing a modular design of the air supply device 500, so as to allow the selection and combination of fans 530 according to specific needs. For example, according to different power, different air flow or different pressure requirements, fans of different powers and supply pipes of different diameters can be selected to meet the air supply needs of different equipment.

[0069] Advantageously, in the cleaning system, the number of fans 530 may be greater than or equal to the number of supply lines. Figure 2 In the example shown, five fans 530 are provided in the housing 510, and the cleaning system has four supply pipelines, so one of the fans can be used as a backup fan. When other fans fail, the backup fan can be used to supply air without affecting the operation of the entire cleaning system. Figure 2 In the figure, the top cover 520 of the air supply device 500 is provided with heat dissipation holes 521, so that the heat generated by the fan 530 during operation can be dissipated from the shell 510, so that the air supply device 500 can maintain a stable operating temperature and performance during long-term operation, thereby improving work efficiency.

[0070] During operation, if the surface to be cleaned by the camera 700 or the laser radar 600 is affected by deposits and cannot function properly, the camera 700 or the laser radar 600 may send a cleaning request to the ECU. The ECU sends a cleaning instruction based on the cleaning request to the control device 540. The control device 540 activates the fan 530 of the corresponding supply pipe based on the cleaning instruction, thus starting the cleaning mode. When the deposits on the surface to be cleaned by the camera 700 or the laser radar 600 are reduced or completely removed, the camera 700 or the laser radar 600 may send a stop cleaning request to the ECU. The ECU instructs the control device 540 to stop the fan 530 of the corresponding supply pipe, thus terminating the cleaning mode. In some embodiments, the cleaning request may be sent when the ratio of the area of the deposit to the area of the surface to be cleaned sensed by the camera 700 or the laser radar 600 reaches a first preset value, and the stop cleaning request may be sent when the ratio of the area of the deposit to the area of the surface to be cleaned sensed by the camera 700 or the laser radar 600 reaches a second preset value. It is understood that the first preset value and the second preset value can be set as needed and are not limited here. In this way, when the amount of attachments on the surface to be cleaned of the camera 700 and laser radar 600 corresponding to the supply pipeline reaches a certain level, the cleaning process can be automatically started, reducing the energy consumption of the cleaning process and the impact on other cameras 700 and laser radar 600 corresponding to the supply pipelines that do not need to be cleaned, ensuring the optimization of cleaning efficiency and effect.

[0071] exist Figure 1 The laser radar 600 corresponding to each supply pipeline and the cleaning device provided on the surface 620 of the laser radar 600 are shown in FIG. Figures 3 to 13 A cleaning device according to an embodiment of the present application is described in detail.

[0072] Combine Figures 3 to 6As shown, the cleaning device 110 includes a cleaning body 111, in which a flow channel is provided for the cleaning fluid to flow through. The cleaning body 111 is provided with an inlet 112 and an outlet 113 along the cleaning direction. The inlet 112 is connected to the supply line to provide the cleaning fluid for cleaning the laser radar 600, and the outlet 113 is adapted to be arranged toward the surface 610 to be cleaned of the laser radar 600. Specifically, after the cleaning device 110 is fixed to the laser radar 600, the outlet 113 can protrude from the surface 620 of the laser radar 600, that is, the outlet 113 extends from the surface 620 of the laser radar 600 along the cleaning direction in a direction away from the inlet 112, so as to be arranged toward the surface 610 to be cleaned of the laser radar 600. In particular, the outlet 113 is provided with a plurality of holes at intervals, and the plurality of holes can ensure that the cleaning fluid completely covers the surface 610 to be cleaned. In this way, the cleaning fluid at outlet 113 can be more evenly distributed, improving cleaning efficiency. The multiple, spaced holes can focus the cleaning fluid, increasing the wind pressure and fluid velocity at outlet 113, further improving the cleaning effect. In addition, the multiple, spaced holes are more robust than, for example, a single-opening outlet, increasing the structural strength and durability of outlet 113, helping to extend the service life of cleaning device 110. The multiple, spaced holes can also prevent larger foreign matter from entering outlet 113, reducing damage to cleaning device 110 and the equipment being cleaned.

[0073] Combine Figure 7 and Figure 8 As shown, the plurality of holes include a first group of holes 113a, a middle group of holes 113c, and a second group of holes 113b, wherein the middle group of holes 113c is arranged in the middle of the outlet 113, and the first group of holes 113a and the second group of holes 113b are arranged symmetrically with respect to the middle group of holes 113c. In particular, at least a portion of the adjacent edges of two adjacent holes are connected or overlapped along the cleaning direction of the cleaning body 111. That is, when the cleaning body 111 is observed along the cleaning direction of the cleaning body 111, the adjacent edges of the two adjacent holes are at least connected or overlapped, so that the cleaning fluid discharged from the outlet 113 can completely cover the surface to be cleaned without any gaps. Preferably, each hole has at least an edge extending along the cleaning direction, and the edge is inclined at a preset angle relative to the longitudinal direction D1 of the cleaning body, where the longitudinal direction D1 is Figure 8 The approximate left-right direction shown in Figure 8The axial direction of the inlet 112 is shown by the dotted line in FIG. In some embodiments, the preset angle can be, for example, 30 to 50 degrees, such as 40 degrees. In addition, each hole can be spaced apart from each other. In some embodiments, the distance between each hole can be, for example, 1 mm to 2 mm, such as 1.5 mm. In this way, the outlet 113 can be better adapted to the surface 610 to be cleaned of the laser radar 600, achieving comprehensive cleaning of the surface 610 to be cleaned of the laser radar 600. It will be understood that the preset angles and distances are not limited to these and can be changed as needed.

[0074] exist Figure 8 In the embodiment, each hole in the first and second groups of holes 113a, 113b is configured as a parallelogram, while the central hole 113c is configured as a trapezoid, specifically a regular isosceles trapezoid. It can be seen that the two waistlines of the isosceles trapezoid are parallel to the central axis of each hole in the first and second groups of holes 113a, 113b, respectively. This effectively and evenly distributes the cleaning fluid to the outlet 113, ensuring that the cleaning fluid fully covers the surface 610 to be cleaned of the laser radar 600. It is understood that the shapes of the first, second, and central groups of holes 113a, 113b, and 113c are not limited to these. Each hole in the first, second, and central groups of holes 113a, 113b, and 113c can be configured, for example, as a rectangle, trapezoid, triangle, or the like. Preferably, the triangles herein are regular equilateral triangles.

[0075] Reference Figure 6 The cleaning body 111 includes a first plate 111a and a second plate 111b that are connected in a detachable manner. The outlet 113 can be arranged on the second plate 111b to discharge the cleaning fluid approximately along a direction D3, which is approximately perpendicular to the second plate 111b. In this way, the plate-shaped cleaning body 111 is easy to fix to the surface of the laser radar 600, and the cleaning body 111 with two detachable plates reduces the complexity of the cleaning device 110 in the manufacturing process. Each plate can be produced independently and then assembled together. When a problem occurs with a plate, the damaged plate can be replaced separately instead of the entire cleaning device 110, saving costs and resources. It is understandable that the outlet 113 can also be set on the first plate 111a according to the layout orientation of the cleaning device 110, so as to be suitable for discharging the cleaning fluid toward the surface to be cleaned 610.

[0076] In some embodiments, the cleaning body 111 is provided with a first clamping portion 114 adjacent to the inlet 112 and a second clamping portion 115 adjacent to the outlet 113 to clamp the first plate 111a to the second plate 111b. Figure 10 As shown, the first clamping portion 114 includes, for example, Figure 10The first portion 114a and the second portion 114b are positioned in the manner shown, and the first portion 114a and the second portion 114b are engaged with each other to seal the cleaning body 111. Figure 11 and Figure 12 As shown, the second clamping portion 115 includes, for example, Figure 11 The third portion 115a and the fourth portion 115b are shown in the illustrated position, and the third portion 115a and the fourth portion 115b are engaged with each other to further seal the cleaning body 111. Figure 10 and Figure 12 In the embodiment, the first clamping portion 114 and the second clamping portion 115 are clamped to each other through two parts that fit in a stepped manner, and an interference fit can be used between the two parts to increase the sealing of the cleaning body 111.

[0077] Continue to refer to Figure 6 The end of the first plate 111a or the second plate 111b where the outlet 113 is located is provided with a first guide portion 116 extending substantially vertically. Figure 6 In the illustrated orientation, when the first guide portion 116 is disposed on the first plate 111a, the first guide portion 116 extends downwardly and beyond the second plate 111b, generally in a direction D3 perpendicular to the first plate 111a. When the first guide portion 116 is disposed on the second plate 111b, the first guide portion 116 extends upwardly and beyond the surface of the first plate 111a, generally in a direction D3 perpendicular to the second plate 111b. This guide portion guides the cleaning fluid generated during the cleaning process, preventing it from being lost and improving cleaning efficiency and effectiveness. It also effectively prevents dust, rainwater, or other debris from entering the interior of the laser radar 600 through the top or sides of the cleaning body 111, maintaining the laser radar 600 in working order. Furthermore, the first guide portion 116 provides additional protection, preventing external objects from directly impacting or abrading the cleaning body 111 and the laser radar 600, thereby extending the service life of the cleaning device 110 and the laser radar 600.

[0078] In some embodiments, the cleaning body 111 is constructed in a fan-shaped shape with a gradually increasing size from the inlet 112 toward the outlet 113. The fan-shaped shape with a gradually increasing size can slow down the speed of the cleaning fluid, prevent turbulence and instability caused by too fast cleaning fluid, help to evenly cover the surface 610 to be cleaned of the laser radar 600, and enable the outlet 113 to cover a larger area, ensuring that the cleaning fluid is evenly distributed on the surface 610 to be cleaned of the laser radar 600, thereby improving the cleaning effect. In addition, the cleaning body 111 is provided with a mounting portion 117 between the inlet 112 and the outlet 113, so that the cleaning device 110 can be fixed to the surface 620 of the laser radar 600 via a fastener passing through the mounting portion 117. In addition, as Figure 7 and Figure 8As shown in FIG, the bottom of the cleaning body 111, that is, the surface of the second plate 111b, may also be provided with an outwardly protruding joint 118, and the surface 620 of the laser radar 600 may be provided with a recess (not shown) that matches the joint 118, so as to further fix the cleaning device 110 to the surface 620 of the laser radar 600. It is understood that the joint 118 can be provided on the first plate 111a according to the arrangement orientation of the cleaning device 110, so as to be suitable for fixing to the laser radar 600.

[0079] In some embodiments, a plurality of second guides 119 are provided in the cleaning body 111, that is, a plurality of second guides 119 are provided in the first plate 111a and the second plate 111b. The plurality of second guides 119 extend between the inlet 112 and the outlet 113 and are spaced apart from each other along a direction D2 that is substantially perpendicular to the cleaning direction, so as to help the cleaning fluid be evenly distributed from the inlet 112 to the outlet 113. Here, the direction D2 is substantially the same as the transverse direction of the cleaning body 111. Figure 13 Figure 1 shows the second guides 119 within the second plate 111b. It is understood that similarly arranged second guides can also be provided within the first plate 111a. This effectively distributes the cleaning fluid evenly, allowing it to flow along a specific path. This prevents turbulence and irregular flow within the cleaning body 111, helping to improve fluid stability and cleaning efficiency. The second guides 119 are spaced apart along direction D2 to ensure even distribution of the cleaning fluid throughout the cleaning area, preventing it from concentrating at a single point, thereby achieving a more uniform cleaning effect.

[0080] Reference Figure 14 The additional cleaning device 120 is disposed on the surface of the camera 700 and includes a cleaning body 121. A flow channel for cleaning fluid is provided within the cleaning body 121. Similarly, the cleaning body 121 is provided with an additional inlet 122 and an additional outlet 123 along the cleaning direction. The additional inlet 122 is connected to a supply line to provide cleaning fluid for cleaning the camera 700, and the additional outlet 123 is disposed toward the surface 710 to be cleaned of the camera 700. Furthermore, the camera 700 also includes a support member 720, which is used to secure the camera 700 to, for example, an unmanned vehicle, improving the stability of the camera 700 during operation. The cleaning body 121 also includes a snap-fitting portion 124, which snaps onto the snap-fitting portion 124 of the cleaning body 121 to secure the additional cleaning device 120 to the camera 700, improving the stability of the additional cleaning device 120 during cleaning and further enhancing the cleaning effect.

[0081] The following will refer to Figures 15 to 19 The four supply lines of the cleaning system of the present application are described in detail.

[0082] exist Figures 15 to 19 In the embodiment, each supply pipeline generally includes an air intake pipeline, a radar air intake branch connected to a cleaning device, and a camera air intake branch connected to an additional cleaning device. The air intake pipeline is connected to the radar air intake branch and the camera air intake branch respectively via connectors. Figure 15 A schematic diagram of a first supply pipeline is shown. The air inlet of the air inlet pipeline 130 is connected to a blower 530 in the air supply device 500 (not shown), and its air outlet is connected to a first connector 140. The first connector 140 has three ends: a first end of the first connector 140 is connected to the air inlet pipeline 130, a second end of the first connector 140 is connected to the radar air inlet branch 150, and a third end of the first connector 140 is connected to the camera air inlet branch 160. In this embodiment, the radar air inlet branch 150 is connected to one cleaning device 110, and the camera air inlet branch 160 is connected to five additional cleaning devices 120. It will be understood that the number of cleaning devices 110 and additional cleaning devices 120 is not limited to that shown in the figure and can be changed as needed. In particular, the first end, the second end, and the third end of the first connecting member 140 have substantially the same diameter. This substantially same diameter enables the camera air intake branch 160 to obtain cleaning fluid having a pressure substantially consistent with that of the radar air intake branch 150. In this way, the camera air intake branch 160 can include multiple additional cleaning devices 120 without affecting the cleaning effect due to insufficient cleaning fluid. Figure 15 In the figure, the first connecting piece 140 has a roughly Y-shape. The Y-shaped connecting piece can provide a smoother fluid path, achieve a smooth transition, reduce the sharp turns and vortices of the cleaning fluid at the first connecting piece 140, thereby reducing resistance and air volume loss. In addition, the Y-shaped connecting piece can smoothly distribute the main fluid from the intake pipe 130 to the two branches, ensuring that the cleaning fluid is evenly distributed in each branch, thereby achieving uniform fluid distribution.

[0083] In this embodiment, the camera air intake branch 160 includes a first camera air intake branch 162 and a second camera air intake branch 163. The first camera air intake branch 162 and the second camera air intake branch 163 are connected to the first connector 140 via the second connector 161, and then connected to the air intake pipe 130. The first end of the second connector 161 is connected to the first connector 140, and the second end of the second connector 161 is connected to the second camera air intake branch 163. It can be understood that in some embodiments, the first end of the second connector 161 can also be directly connected to the air intake pipe 130 as needed. In this case, the first supply pipe may only include the air intake pipe 130 and the camera air intake branch 160. In particular, the side wall of the second connector 161 is provided with a plurality of through portions at intervals along the air intake direction, and the first camera air intake branch 162 is connected to the through portion of the side wall of the second connector 161. Figure 15In the embodiment, second connecting member 161 has a generally conical structure, tapering from the first end toward the second end along the air intake direction. This ensures consistent cleaning fluid pressure at the inlet 165 of each through-hole on the sidewall. This means that the cleaning fluid flowing into each through-hole has a consistent pressure, and thus, the cleaning fluid flowing out of each through-hole has a consistent pressure. First camera air intake branch 162 includes multiple first camera air intake branches, which are connected to the sidewall of second connecting member 161 at intervals along the air intake direction for multiple additional cleaning devices 120. Thus, through second connecting member 161, camera air intake branch 160 can be connected to multiple additional cleaning devices 120 to clean multiple cameras 700. The conical shape of the connecting member evenly distributes cleaning fluid to each first camera air intake branch within first camera air intake branch 162, ensuring that each additional cleaning device 120 receives cleaning fluid at a consistent pressure, thereby improving the consistency of the cleaning effect. Figure 15 It is shown in the figure that the first camera air intake branch 162 includes three first camera air intake branches. It can be understood that the number of multiple first camera air intake branches is not limited to that shown in the figure, for example, it can include two first camera air intake branches or four first camera air intake branches.

[0084] Continue to refer to Figure 15 The second end of the second connecting member 161 is connected to the second camera air intake branch 163 , and the second camera air intake branch 163 is connected to the two additional cleaning devices 120 via the third connecting member 164 . Figure 15 The third connecting member 164 shown in FIG. 1 has a structure substantially similar to that of the first connecting member 140 , namely, it includes three ends having substantially the same diameter and a generally Y-shaped structure. However, the diameters of the three ends of the third connecting member 164 are smaller than those of the three ends of the first connecting member 140 . It is understood that the structure of the third connecting member 164 is not limited to this. For example, the third connecting member 164 may also have a structure substantially similar to that of the second connecting member 161 , namely, a generally conical structure, to ensure consistent and even pressure distribution of the cleaning fluid. Specifically, the third connecting member 164 may alternatively include two ends extending through the air inlet direction, may include a sidewall with a plurality of through-portions spaced apart along the air inlet direction, and may have a generally conical structure that tapers in size along the air inlet direction to ensure consistent cleaning fluid pressure at the inlets of each through-portion of the sidewall of the third connecting member. In addition, the number of additional cleaning devices 120 in the second camera air intake branch 163 is not limited to that shown in the figure and can be changed as needed. For example, the second camera air intake branch 163 can include only one additional cleaning device 120. In this case, the third connecting member 164 may not be required.

[0085] Figure 16 A schematic diagram of the second supply pipeline is shown, and it can be seen that the second supply pipeline has a layout roughly the same as the first supply pipeline. Specifically, the first connector 240 of the second supply pipeline is connected between the air intake pipeline 230 and the radar air intake branch 250 and the camera air intake branch 260, and the camera air intake branch 260 includes a first camera air intake branch 262 and a second camera air intake branch 263. The radar air intake branch 250 is connected to the cleaning device 210. The second connector 261 is connected between the first connector 240 and the first camera air intake branch 262 and the second camera air intake branch 263. Figure 16 In the embodiment, second connecting member 261 also has a generally conical structure, its size gradually decreasing along the air intake direction to ensure consistent cleaning fluid pressure at the inlet 265 of each through-portion on the sidewall. First camera air intake branch 262 includes multiple first camera air intake branches. Each of the multiple first camera air intake branches and / or second camera air intake branches 263 includes one or more additional cleaning devices 220. Multiple additional cleaning devices 220 are connected to first camera air intake branch 262 and / or second camera air intake branch 263 via third connecting member 264. The specific function of the second supply line can be found in the aforementioned description of the first supply line embodiment and will not be repeated here.

[0086] Figure 17 The schematic diagram of the third supply line is shown, and the third supply line includes a fourth connector 340, and the fourth connector 340 has three ends. The first end of the fourth connector 340 is connected to the air intake line 330, the second end is connected to the radar air intake branch 350, and the third end is connected to the camera air intake branch 360. Figure 17 In the third supply line shown in FIG, the radar air intake branch 350 is connected to a cleaning device 310, and the camera air intake branch 360 is connected to an additional cleaning device 320. It is understood that the number of cleaning devices 310 and additional cleaning devices 320 connected to the radar air intake branch 350 and the camera air intake branch 360 is not limited to this and can be changed as needed. The fourth connecting member 340 has a Y-shape. Unlike the first and third connecting members described above, the first and second ends of the fourth connecting member 340 have approximately the same diameter, and the third end has a smaller diameter than the first and second ends. This allows the cleaning system to precisely control fluid distribution based on the different fluid requirements of the lidar 600 and the camera 700, ensuring that the corresponding cleaning devices receive the required fluid volume, thereby improving the cleaning effect.

[0087] Figure 18 and Figure 19The fourth supply line is shown in the figure. The fourth supply line includes a fourth connector 440. The fourth connector 440 has three ends. The first end of the fourth connector 440 is connected to the air intake line 430, the second end is connected to the radar air intake branch 450, and the third end is connected to the camera air intake branch 460. In the fourth supply line, the radar air intake branch 450 is connected to a cleaning device 410. Figure 15 and Figure 16 Similar to the illustrated embodiment, the camera air intake branch 460 is connected to two additional cleaning devices 420 via a third connector 464. The third connector 464 has a structure similar to the first connectors 140 and 240, namely, a generally Y-shaped structure, but with a smaller diameter. It should be understood that the number of cleaning devices 410 and additional cleaning devices 420 connected to the radar air intake branch 450 and the camera air intake branch 460 is not limited to this and can be changed as needed. The fourth connector 440 in the fourth supply line has a similar structure to the fourth connector 340 in the third supply line. That is, when the camera air intake branch 460 includes two additional cleaning devices 420, fourth connectors 440 with different diameters can also be used to ensure that the corresponding cleaning devices receive the required amount of fluid, thereby improving the cleaning effect.

[0088] like Figures 20 to 23 As shown, the cleaning system according to another embodiment of the present application may generally include a supply pipeline. Figure 20 It can be seen that the supply pipeline is connected to a plurality of additional cleaning devices 810 to clean the equipment to be cleaned, where the equipment to be cleaned can be the camera 700. Figures 20 to 22 As shown, the cleaning system according to this embodiment includes an air supply device 900, which includes a housing 910, a fan 930, and an electrical device 940. The fan 930 is disposed within the housing 910 and is used to supply air to multiple additional cleaning devices 810. The electrical device 940 is disposed on the side wall 920 of the housing 910. The electrical device 940 can be, for example, an electrical connector to electrically connect to the fan 930. At this time, when the device to be cleaned senses that it is affected by surface attachments and cannot operate normally, the device to be cleaned will send a cleaning request to the ECU. Based on the cleaning request, the ECU instructs the electrical device 940 to turn on, thereby energizing the fan 930 and starting the cleaning. Here, using a single fan 930 to supply air to multiple additional cleaning devices 810 eliminates the need to configure a separate fan for each additional cleaning device 810, can reduce production and manufacturing costs, and save space occupied by the air supply device 900.

[0089] exist Figure 20In the embodiment, the air supply device 900 is connected to a plurality of additional cleaning devices 810 via a supply pipeline. Specifically, the supply pipeline as a whole includes an air intake pipeline 820 and an additional air intake branch, and the additional air intake branch is connected to a plurality of additional cleaning devices 810 to clean a plurality of equipment to be cleaned. The cleaning system also includes a plurality of connectors, and the plurality of connectors are connected to the plurality of additional cleaning devices 810 through the supply pipeline. Specifically, the cleaning system includes a fourth connector 821, and the additional air intake branch includes a first additional air intake branch 830 and a second additional air intake branch 840. The fourth connector 821 has three ends. The first end of the fourth connector 821 is connected to the air intake pipeline 820, the second end is connected to the first additional air intake branch 830, and the third end is connected to the second additional air intake branch 840, wherein the second additional air intake branch 840 is connected to one additional cleaning device 810. It can be understood that the number of additional cleaning devices 810 is not limited to this and can be changed as needed. The fourth connecting member 821 has a Y-shape, with the first and second ends of the fourth connecting member 821 having substantially the same diameter, and the third end having a smaller diameter than the first and second ends. This allows the cleaning system to precisely control fluid distribution based on the varying fluid requirements of the equipment being cleaned, ensuring that each additional cleaning device 810 receives the required fluid volume, thereby improving cleaning effectiveness.

[0090] like Figure 20 As shown, the cleaning system further includes a first connecting member 835, and the first additional air intake branch 830 includes a plurality of third additional air intake branches 831 ( Figure 20 (Two third additional air inlet branches 831 are shown in the figure), and a first connecting member 835 is connected between the first additional air inlet branch 830 and the two third additional air inlet branches 831. The first connecting member 835 has a generally Y-shaped structure and includes three ends with substantially the same diameter. This provides a relatively smooth fluid path, reduces sharp turns and vortices of the cleaning fluid at the first connecting member 835, and achieves uniform fluid distribution.

[0091] In addition, the cleaning system further includes a plurality of second connecting members 836. Each of the plurality of third additional air intake branches 831 includes a fourth additional air intake branch 832 and a fifth additional air intake branch 833. The second connecting members 836 are connected between the third additional air intake branch 831 and the fourth additional air intake branch 832 and the fifth additional air intake branch 833. The second connecting members 836 include a first end and a second end extending along the air intake direction. The second connecting member 836 also includes a sidewall having a plurality of through-portions spaced apart along the air intake direction. The second connecting member 836 has a generally tapered structure that tapers from the first end toward the second end to ensure uniform cleaning fluid pressure at the inlets 838 of each through-portion on the sidewall. In this way, the first end of the second connecting member 836 is connected to the third additional air intake branch 831, the second end of the second connecting member 836 is connected to the fifth additional air intake branch 833, and the through portion of the side wall of the second connecting member 836 is connected to the fourth additional air intake branch 832, so as to evenly distribute the cleaning fluid to the fourth additional air intake branch 832 and the fifth additional air intake branch 833, ensuring that each additional cleaning device 810 can obtain cleaning fluid with consistent pressure, thereby improving the consistency of the cleaning effect.

[0092] Additionally, the cleaning system further includes a plurality of third connecting members 837, and the plurality of fifth additional air intake branches 833 each include a sixth additional air intake branch 834. Figure 20 The sixth additional air intake branch 834 is connected to two additional cleaning devices 810, and the third connecting member 837 is connected between the fifth additional air intake branch 833 and the sixth additional air intake branch 834. The third connecting member 837 has a generally Y-shaped structure and includes three ends of approximately the same diameter. This provides a smoother fluid path, reduces sharp turns and vortices of the cleaning fluid at the third connecting member 837, and achieves uniform fluid distribution. It will be understood that the number of additional cleaning devices 810 in the sixth additional air intake branch 834 is not limited to that shown in the figure and can be modified as needed. For example, the sixth additional air intake branch 834 may include only one additional cleaning device 810, in which case the third connecting member 837 may not be required.

[0093] It should be understood here that the embodiments shown in the figures only show the optional shapes, sizes and arrangements of the cleaning system and cleaning device according to the present application. However, they are only illustrative and not restrictive. Other shapes, sizes and arrangements may also be adopted without departing from the concept and scope of the present application.

However, it is understood that, based on the creative ideas of this application, those skilled in the art may make various changes and improvements to the above-disclosed concepts, all of which fall within the scope of protection of this application.
