The vehicle may be an autonomous vehicle, and the following description will take the vehicle as an example of an autonomous vehicle, but this is not meant to limit the present application in any way. In order to implement the autopilot function of a vehicle, referring to fig. 1, fig. 1 is a schematic diagram of a vehicle 1000 according to some embodiments of the present disclosure. The vehicle 1000 includes a vehicle body 100a and a cleaning device 100b, and the cleaning device 100b is mounted on the vehicle body 100 a. For example, the cleaning device 100b may be mounted at a front end, a rear end, a side, or the like of the vehicle body 100a to realize an automatic driving (unmanned) function of the vehicle. In this embodiment and the following embodiments, the cleaning device 100b is mounted on the front end of the vehicle body 100 a.

In addition, in order to better implement the autopilot function of the vehicle 1000, the vehicle 1000 may further include various types of sensors, such as a radar, a camera, bluetooth, a wireless communication module, etc., to which the present disclosure is not limited in particular.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a device to be cleaned 100b according to some embodiments of the disclosure. Specifically, the cleaning device 100b includes a cleaning member and a cleaning member 100. The cleaning member may be a radar, a camera, bluetooth, a wireless communication module, or the like as described above, and hereinafter, the cleaning member is described as the radar 200, which is not meant to be a particular limitation of the present application.

For convenience of the following description, an XYZ coordinate system is established, a thickness direction of the radar 200 is defined as a Z-axis direction, a width direction of the radar 200 is defined as an X-axis direction, and a length direction of the radar 200 is defined as a Y-axis direction. It is understood that the coordinate system setting of the radar 200 may be flexibly set according to actual needs.

The radar 200 may be a laser radar, a millimeter wave radar, or an ultrasonic radar, for example. Taking a laser radar as an example, the working principle of the laser radar is that the laser radar compares echo signals reflected by a target with emission signals by emitting laser beams outwards to obtain relevant information of the target, such as parameters of the distance, azimuth, altitude, speed, shape and the like of the target, so that surrounding environment point cloud data is quickly created to sense surrounding information of vehicles, pedestrians, lane lines and the like. It is understood that the signals transmitted and received by the millimeter wave radar are millimeter waves, and the signals transmitted and received by the ultrasonic radar are ultrasonic waves. For convenience of explanation, a lidar will be described below as an example.

With continued reference to fig. 2, the radar 200 may have a cylindrical shape, an elliptical cylindrical shape, a cubic shape, a rectangular parallelepiped shape, and the like, and the present disclosure describes the radar 200 as a generally rectangular parallelepiped shape.

The radar 200 includes a housing, a transmitter (not shown in the drawings) for transmitting a laser beam, and a receiver (not shown in the drawings) for receiving the laser beam. The transmitter and the receiver are both located within the housing.

The radar 200 (for example, on the housing) has a working surface 201 facing the outside of the vehicle body 100 a. The laser beam from the transmitter is directed outward through the working surface 201 and the receiver receives the signal reflected back to the working surface 201 by the external object.

Radar 200 also includes a first wall 202, a second wall 203, a third wall 204, and a fourth wall 205 coupled to work surface 201, and a fifth wall 206 opposite work surface 201. The first wall surface is at one end of the working surface in the second direction (i.e. the Z-axis direction in fig. 2), the first wall surface 202 is opposite to the fourth wall surface 205, and the second wall surface 203 is opposite to the third wall surface 204. At least part of the first wall 202, the second wall 203, the third wall 204, the fourth wall 205, and the fifth wall 206 are accommodated inside the vehicle body 100 a.

The cleaning member 100 is mounted on the radar 200 for cleaning the working surface 201 of the radar 200.

Specifically, the cleaning member 100 may be mounted on at least one of the working surface 201, the first wall surface 202, the second wall surface 203, the third wall surface 204, and the fourth wall surface 205. In one embodiment, the cleaning member 100 may be at an end of the working surface 201 in the second direction (i.e., the Z-axis direction in fig. 2), that is, an end of the working surface 201 that meets the first wall surface 202. The cleaning member 100 is attached to the first wall 202. The present embodiment and the following embodiments will be described by taking the cleaning member 100 attached to the first wall surface 202 as an example, but this is not meant to limit the present disclosure in any way.

With continued reference to fig. 2, in particular, the cleaning member 100 includes a housing 10.

Referring to fig. 3, fig. 3 is a schematic structural diagram of the cleaning member 100 in fig. 2 when cleaning liquid enters the cavity 11. The housing 10 encloses a cavity 11. The shell 10 is provided with a water inlet 12 and a water outlet 13 which are communicated with the cavity 11. The water outlet 13 is directed towards the working surface 201 of the radar 200.

The cleaning component 100 can spray cleaning liquid outwards from the water outlet 13, and the cleaning liquid is sprayed to the working surface 201 of the radar 200 to remove water stains, mud, insects and other foreign matters attached to the working surface 201 of the radar 200, prevent the radar 200 from normally transmitting laser signals and receiving echo signals due to the attachment of the foreign matters on the working surface 201, and ensure the working performance of the radar 200.

In order to ensure that the cleaning member 100 cleans the working surface 201 of the radar 200, the cleaning liquid sprayed to the working surface 201 of the radar 200 needs to have a certain pressure. Therefore, the cleaning liquid injected into the cavity 11 of the cleaning member 100 through the water inlet 12 needs to have a certain water pressure. Based on this, the cleaning solution is easy to generate the vortex M when entering the cavity 11 through the water inlet 12, the cleaning solution forming the vortex M is easy to concentrate in the small area in the cavity 11, the cleaning solution cannot be guaranteed to fill the whole cavity 11 of the cleaning member 100, and further the cleaning solution cannot be uniformly sprayed to the working surface 201 of the radar 200 through the water outlet 13, so that the working surface 201 of the radar 200 has a cleaning dead angle, and cannot be cleaned in all directions.

In order to solve the above-mentioned problems, please refer to fig. 4 and 5, fig. 4 is a schematic structural view of the cleaning member 100 in fig. 2; fig. 5 is a schematic view of the cleaning member 100 of fig. 4, which is taken along the line L1 with the intake port 16 omitted from view a. Other embodiments of the present disclosure provide a cleaning member 100, the cleaning member 100 further comprising a diverter plate 20 on the basis of the above-described embodiments. The flow dividing plate 20 extends in the flow direction of the fluid, and the flow dividing plate 20 divides the chamber 11 into a plurality of flow passages 21. Each flow passage 21 is respectively communicated with the water inlet 12 and the water outlet 13. Specifically, referring to fig. 4 and 5, the flow dividing plate 20 may be connected to an inner wall of the cavity 11, the flow dividing plate 20 divides the cavity 11 into a plurality of flow channels 21, one end of the flow channel 21 is connected to the water inlet (the water inlet is omitted in fig. 5), and the other end of the flow channel 21 is connected to the water outlet 13.

Specifically, on the one hand, when the cleaning liquid enters the cavity 11 from the water inlet 12 and is sprayed onto the flow dividing plate 20, the cleaning liquid can be divided into a plurality of water streams flowing in different directions under the action of the flow dividing plate 20. On the other hand, after the cleaning solution enters the cavity 11 through the water inlet 12, if a vortex is formed, due to the fact that the vortex has a certain rotation in the cavity, when the rotating vortex collides with the flow dividing plate 20, the flow dividing plate 20 can block the vortex, and then the vortex is broken up. Through the above process, the generation of the vortex M and the scattering of the vortex are avoided, so that the concentration of the cleaning liquid in the small area in the cavity 11 is avoided, the cleaning liquid is uniformly distributed in each flow channel 21 after contacting the flow dividing plate 20, and the cleaning liquid is further sprayed to the working surface 201 of the radar 200 through each flow channel 21. Therefore, the cleaning member 100 can facilitate the cleaning of the working surface 201 of the radar 200 without dead angles in all directions, and the cleaning efficiency of the cleaning member 100 can be improved.

With continued reference to fig. 5, in some embodiments, the cavity 11 includes a first cavity portion 112 and a second cavity portion 113. The flow dividing plate 20 is provided to the first cavity portion 112 to divide the first cavity portion 112 into a plurality of flow passages 21. The second cavity portion 113 is located between the first cavity portion 112 and the water outlet 13. And, the first cavity portion 112 communicates with the water outlet 13 via the second cavity portion 113. In this way, the flow channels 21 can extend to a position at a distance from the water outlet 13, and the second cavity portion 113 between the flow channels 21 and the water outlet 13 can serve as a junction 111, through which the cleaning liquid enters the junction 111 through the respective flow channels 21 and is sprayed onto the working surface 201 of the radar 200 through the water outlet 13. The merging of the cleaning liquid through the merging section 111 can avoid the formation of gaps of the cleaning liquid between the adjacent flow passages 21. In this way, the cleaning solution can be uniformly distributed in the water outlet 13, and the formation of a water flow gap of the cleaning solution at the position of the water outlet 13 corresponding to the flow dividing plate 20 due to the arrangement of the flow dividing plate 20 can be avoided, so that the cleaning solution can be uniformly sprayed to the working surface 201 of the radar 200.

In some embodiments, the flow dividing plate 20 may include a plurality of small plates distributed along the flow direction of the cleaning liquid, and the small plates may be spaced so that the cleaning liquid in each flow channel 21 is converged through the gaps between the adjacent small plates, thereby enhancing the fluidity of the cleaning liquid and reducing the weight of the flow dividing plate 20. The flow dividing plate 20 may also be an integral flow dividing plate 20 extending in the direction of flow of the cleaning liquid. The cross-section of the flow channel 21 may be square, circular, oval, profiled, etc., and the flow splitter plate 20 is arranged according to the different shapes of the cross-section of the flow channel 21. The flow dividing plate 20 has a simple structure, is convenient to produce, has lighter weight, does not increase the weight of the cleaning member 100, and is convenient to install.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a cleaning member 100 according to other embodiments of the present disclosure. The diverter plate 20 may extend to connect with the inner peripheral surface of the water outlet 13. Thus, the generation of the vortex can be effectively avoided, and the uniformity of the cleaning of the working surface 201 of the radar 200 by the cleaning member 100 can be improved.

Based on the cleaning member 100 being at one end of the working surface 201 in the second direction. To increase the coverage of the working surface 201 by the water flow emitted from the water outlet 13, in some embodiments the water outlet 13 extends in a first direction (i.e. the X-axis direction in fig. 6), wherein the first direction is perpendicular to the second direction. Thus, the cleaning efficiency and the cleaning effect of the working surface 201 can be advantageously improved.

On this basis, in order to further improve the cleaning effect and the cleaning efficiency of the cleaning member 100 on the working surface, both ends of the working surface 201 in the first direction are located between both ends of the water outlet 13 in the first direction.

The working surface 201 includes a first end and a second end along a first direction, and a plane in which the first end and the second end lie is a first plane. The water outlet 13 comprises a third end and a fourth end in the first direction. It should be noted that "the two ends of the working surface 201 in the first direction are located between the two ends of the water outlet 13 in the first direction" means that the orthographic projection of the third end on the first plane overlaps the first end or the orthographic projection of the third end on the first plane is located on the side of the first end away from the second end; the orthographic projection of the fourth end on the first plane overlaps with the second end or the orthographic projection of the fourth end on the first plane is positioned on one side of the second end far away from the first end.

To further enhance the cleaning effect of the cleaning member 100, in some embodiments, the manifold 20 is multiple. The plurality of flow dividing plates 20 are disposed at intervals in the first direction. A flow passage 21 is formed between two adjacent flow dividing plates 20.

In some embodiments, the second direction is an up-down direction. The cleaning member 100 is provided at the upper end of the working surface 201. At this time, the first wall surface is the top surface of the radar. Therefore, the water outlet 13 is close to the upper edge of the working surface 201, so that the cleaning component 100 sprays the cleaning liquid, and the cleaning liquid flows from the upper edge of the working surface 201 to the bottom edge of the working surface 201 under the combined action of the spraying direction and the gravity of the cleaning component, so that the cleaning liquid is ensured to flow through each area of the working surface 201, and the working surface 201 is completely cleaned.

Of course, in the case where the cleaning liquid is discharged from the water outlet 13 at a high speed, the area of the working surface 201 of the radar 200 is small, or the like, the cleaning member 100 may be mounted on the side wall surface or the bottom wall surface of the radar 200, the cleaning member 100 may extend toward the side edge or the bottom edge of the working surface 201, and the cleaning liquid may flow from one side edge to the other side edge of the working surface 201 or from the bottom edge to the top edge of the working surface 201, so that the working surface 201 is cleaned entirely.

In some embodiments, the working surface 201 is inclined with respect to the first wall surface 202 in a direction from an end of the working surface 201 near the first wall surface 202 to an end of the working surface 201 remote from the first wall surface 202. In this way, the cleaning solution sprayed by the cleaning member 100 mounted on the first wall 202 can be more comprehensively sprayed on the working surface 201, which is beneficial to improving the cleaning efficiency of the radar 200.

Referring to fig. 7, fig. 7 is an exploded view of a cleaning member 100 provided in some embodiments of the present disclosure. In some embodiments, the housing 10 includes a first housing portion 101 and a second housing portion 102, where the first housing portion 101 is connected to an outer wall of the radar 200, i.e., a first wall 202 of the radar 200, and is attached to the first wall 202 of the radar 200, and the first housing portion 101 encloses a first cavity 101a.

The second housing part 102 is connected to the first housing part 101 and extends towards the working surface 201 of the radar 200, the second housing part 102 encloses a second cavity 102a, the second cavity 102a communicates with the first cavity 101a, and the water outlet 13 is arranged in the second housing part 102.

The first housing part 101 is attached to the first wall surface 202 of the radar 200, so that the cleaning member 100 can be positioned and mounted conveniently, the second housing part 102 extends towards the working surface 201 of the radar 200, the cleaning member 100 can spray cleaning water onto the working surface 201 of the radar 200 conveniently, and the cleaning efficiency of the cleaning member 100 is further improved.

With continued reference to fig. 7, in some embodiments, the working surface 201 is a curved surface that arches away from the center of the radar 200. In this way, the area of the working surface 201 is advantageously increased, and when the radar 200 transmits signals outwards through the working surface 201, the coverage area of the signals can be increased, thereby advantageously improving the monitoring effect of the radar 20. Of course, it will be appreciated that in other examples, the working surface 201 may be planar.

On the basis of this, the surface of the second housing part 102 facing the working surface 201 presents an arc surface that arches away from the radar 200. In this way, the adaptability of the cleaning member 100 and the radar 200 is better, which is beneficial for the cleaning member 100 to be arranged on the radar 200, and further improves the assembly efficiency of the cleaning member 200. Of course, it will be appreciated that in other examples, the surface of the two housing portions 102 facing the working surface 201 may be planar.

For example, the centerlines of the arcuate working surface 201 and the surface of the arcuate second housing portion 102 facing the working surface 201 may be parallel or coincident. In other examples, the curved working surface 201 and the centre line of the surface of the curved second housing part 102 facing the working surface 201 may also have an angle.

With continued reference to fig. 7, in some embodiments, the outlet 13 is arcuate with a centerline of the outlet 13 coincident with or parallel to a centerline of the surface of the second housing portion 102 facing the working surface 201. In this way, the water outlet 13 is designed to have an arc adapted to the working surface 201, and the cleaning solution sprayed from the water outlet 13 can be more uniformly sprayed to the working surface 201, so as to avoid uneven cleaning of the convex surface and the concave surface of the working surface 201 due to the arc.

With continued reference to fig. 7, in some embodiments, the housing 10 includes a base 14 and an upper cover 15, the base 14 is connected to the radar 200, the upper cover 15 is located on a side of the base 14 away from the radar 200 and is connected to the base 14, and the upper cover 15 and the base 14 define the cavity 11.

In some examples, when the housing 10 includes the first housing portion 101 and the second housing portion 102 described above, the first housing portion 101 is defined by a portion of the base 14 and a portion of the upper cover 15. The second housing portion 102 is defined by the remainder of the base 14 and the remainder of the upper cover 15.

Specifically, the base 14 and the upper cover 15 may be made of metal, so that the structural strength of the cleaning member 100 is further improved, and a certain water pressure can be borne.

With continued reference to fig. 7, the base 14 includes a mounting member 142. The base 14 may be mounted to the radar 200 by a mount 142. Specifically, the mounting member 142 may include a first mounting portion 142a, a second mounting portion 142b located at both sides of the base 14, and a connecting portion 142c connected between the first and second mounting portions 142a and 142 b. Wherein, the first mounting portion 142a is provided with a first through hole, and the second mounting portion 142b is provided with a second through hole. The second wall 203 and the third wall 204 of the radar 200 are provided with corresponding through-hole structures, and the base 14 is connected to the radar 200 by locking members such as screws and rivets. The connection portion 142c is connected between the first mounting portion 142a and the second mounting portion 142b, so that the structural strength of the base 14 can be further improved.

With continued reference to fig. 7, the base 14 is provided with a third through hole 31, the upper cover 15 is provided with a fourth through hole 32, and the orthographic projection of the third through hole 31 on the upper cover 15 overlaps with the fourth through hole 32, where overlapping refers to overlapping with manufacturing error and assembly error, and is not limited to absolute overlapping. The third through hole 31 and the fourth through hole 32 are provided with screws, bolts or screws to fix the base 14 and the upper cover 15. In other embodiments, the base 14 and the upper cover 15 may be connected by bonding, welding, or the like.

The upper cover 15 is attached to the base 14, and the upper cover and the base are jointly enclosed to form a cavity 11, the cavity 11 extends along the extending direction of the base 14 and the upper cover 15, and the cavity 11 extends to one end of the cleaning component 100 facing the working surface 201 and forms a water outlet 13 at the end. The shell 10 adopts a structure that the base 14 is matched with the upper cover 15, thereby being convenient for production and processing and being more convenient for arranging the splitter plate 20 inside the shell 10; the use of the integrated housing 10 causes a problem in that the flow dividing plate 20 is not easily installed in the cavity 11.

After the radar 200 is cleaned, water drops which are easy to remain on the working surface 201 of the radar 200 easily affect shielding, refraction, scattering and the like of laser signals transmitted and received by the radar 200, so that phenomena of point cloud data distortion and discontinuity are caused, and the working performance of the radar 200 is affected. With continued reference to fig. 7, in order to solve the above problem, in some embodiments, the housing 10 further includes an air inlet 16 in communication with the cavity 11. The air is blown into the cavity 11 through the air inlet 16, and is sprayed out through the water outlet 13, so that the dust, dirt, liquid and other foreign matters remained on the working surface 201 can be thoroughly removed, the cleaning effect is good, and the working performance of the radar 200 can be ensured.

The water inlet 12 is used for conveying cleaning liquid, the air inlet 16 is used for conveying air, and the cleaning liquid and the air are sprayed to the working surface 201 of the radar 200 through the flow channel 21 to clean the working surface 201. The cleaning liquid can be water or water added with the cleaning liquid, and the gas can be air. Through the combined action of the cleaning solution and the gas, the working face 201 of the radar 200 is cleaned, so that the cleaning effect of the working face 201 can be improved, the residual foreign matters on the working face 201 can be thoroughly removed, and the working performance of the radar 200 is ensured.

Specifically, the cleaning solution can be firstly conveyed into the cavity 11 through the water inlet 12, the cleaning solution is firstly utilized to clean the working face 201 of the radar 200, dust, dirt, insects and other foreign matters attached to the working face 201 are removed, then the air is conveyed into the cavity 11 through the air inlet 16, the air is accelerated through the cavity 11 to form high-speed air flow, the high-speed air flow is sprayed out to the working face 201 of the radar 200, the high-speed air flow has a strong impact force, the foreign matters attached to the working face 201 can be thoroughly removed, the residual cleaning solution of the working face 201 is thoroughly removed, the working face 201 is thoroughly and thoroughly cleaned without dead angles, the cleaning effect on the working face 201 can be improved, and the working performance of the radar 200 is ensured.

In other embodiments, the gas may be supplied into the chamber 11 through the gas inlet 16 after the chamber 11 is filled with the cleaning liquid supplied through the water inlet 12, and the chamber 11 may be filled with the cleaning liquid due to the small volume of the chamber 11, approximately simultaneously supplying the cleaning liquid and the gas. The gas generates pressure in the cavity 11, so that the flow of the cleaning liquid can be accelerated, and the cleaning liquid is sprayed from the water outlet 13 to the working surface 201 of the radar 200 after being accelerated in the cavity 11, so that the working surface 201 is cleaned. After cleaning the working surface 201 with the cleaning liquid, the air inlet 16 may continue to operate for a certain period of time to continuously blow high-pressure air to the working surface 201 through the water outlet 13, so as to remove the residual cleaning liquid on the working surface 201.

In some embodiments, the water inlet 12 and the air inlet 16 are located at an end of the cavity 11 away from the water outlet 13, that is, the water inlet 12 and the air inlet 16 may be disposed on a surface of the housing 10 near the first wall 202, which is not meant to be limiting of the disclosure, and the water inlet 12 and the air inlet 16 may be disposed at other positions of the housing 10, such as a surface of the housing 10 facing the second wall 203, a surface of the housing 10 facing the third wall 204, and so on. However, when the water inlet 12 and the air inlet 16 are located at one end of the cavity 11 far away from the water outlet 13, the flow path of the cleaning solution in the cavity 11 can be further prolonged, the capacity in the cavity 11 is smaller, the water pressure can be further increased after the cleaning solution with a certain pressure enters the narrow cavity 11, and the cleaning solution can be more forcefully sprayed out through the water outlet 13 to clean the working surface 201 of the radar 200.

Referring to fig. 8 and 9, fig. 8 is a cross-sectional view of fig. 7 from the perspective B; fig. 9 is an enlarged view at C in fig. 8. In some embodiments, the cross section of the cavity 11 is gradually reduced from the water inlet (the water inlet is omitted in fig. 7 and 8) to the water outlet 13, and after the cleaning solution with a certain pressure enters the cavity 11, the cavity 11 containing the cleaning solution is gradually reduced along the flowing direction of the cleaning solution, so that the water pressure of the cleaning solution is further improved, and the cleaning solution can be sprayed out through the water outlet 13 to clean the working surface 201 of the radar 200 with more force.

In some embodiments, the width d of the water outlet 13 is greater than or equal to 0.05 millimeters and less than or equal to 0.1 millimeters. When the width d of the water outlet 13 is set in the above range, the narrower water outlet 13 allows the cleaning solution to have a certain water pressure to be sprayed on the working surface 201, which is beneficial to cleaning the working surface 201 of the radar 200.
