[0039] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The rapid development of technologies such as big data, cloud computing, and artificial intelligence, along with continuous breakthroughs in the computing power of modern servers and processor modules, has laid a solid foundation for the development of intelligent vehicles. Intelligent vehicles are exhibiting increasingly clear and accurate trends in marker recognition, route recognition, and identity recognition, enabling continuous upgrades and transformations in areas such as autonomous driving and human-vehicle interaction.

[0042] For autonomous driving and human-vehicle interaction, in addition to configuring a precise computing program for the vehicle, it is also necessary to meet the vehicle's hardware requirements. Hardware can usually be achieved by setting up more intelligent display devices or intelligent monitoring devices on the vehicle. Intelligent display devices can be LCD screens or touch screens, and intelligent monitoring devices can be camera modules, etc.

[0043] Considering the existing vehicle design and the requirement for easy observation by relevant personnel, more intelligent display devices or intelligent monitoring devices can be installed in easily visible locations with sufficient installation space. The B-pillar (i.e., the center pillar) area of ​​the vehicle can meet this requirement. The B-pillar area corresponds to the middle position of the vehicle, and from the width direction of the vehicle, the B-pillar area is usually the extreme position of the vehicle's external outline. Therefore, by setting up intelligent display devices or intelligent monitoring devices in the B-pillar area, not only can external personnel easily observe relevant vehicle information, but it is also easy for occupants inside the vehicle to view it in real time. In addition, intelligent display devices or intelligent monitoring devices installed in the B-pillar area can perform better display or monitoring functions.

[0044] It is understandable that the relevant information monitored by the aforementioned intelligent display or monitoring devices can be calculated by a computing program and then used to instruct the vehicle to respond accordingly, such as displaying relevant information. Each step of the intelligent display or monitoring device affects the final calculation result. Therefore, to improve the reliability of the calculation results or to ensure vehicle driving safety, the intelligent display or monitoring devices need to clearly display relevant information or clearly monitor real-time changes in the vehicle's surrounding environment.

[0045] Therefore, in addition to improving the performance of intelligent display devices or intelligent monitoring devices to achieve the above objectives, another important measure can be taken by ensuring the cleanliness of the surfaces of these devices. It is understandable that intelligent display devices or intelligent monitoring devices are susceptible to contaminants such as dust, rainwater, oil stains, and bird droppings, which can limit their normal operation and, to some extent, affect driving safety.

[0046] In view of the above-mentioned situation and problems, this application provides a cleaning device that can clean relevant equipment installed in the B-pillar area to ensure that these devices can perform their basic functions.

[0047] Therefore, in this embodiment of the application, a spray structure is provided near the installation area where the aforementioned related equipment is installed, which enables the cleaning flow to be sprayed toward the installation area. The cleaning flow can clean the related equipment and prevent contaminants from adhering to the related equipment.

[0048] In this embodiment, the clean flow can be an airflow, a liquid flow, or a mixture of airflow and liquid flow. The airflow can be configured with a gas flow rate as needed, the liquid flow can be configured with a liquid flow rate as needed, and the mixture can be configured with different gas-liquid ratios as needed. Here, the gas-liquid ratio is the ratio of airflow to liquid flow in the mixture.

[0049] In general, to install intelligent monitoring equipment in the B-pillar area, a recess is usually provided on the B-pillar, within which the intelligent monitoring equipment can be confined. Intelligent display equipment can be installed on the surface of the B-pillar. Therefore, for the installation of either a single intelligent monitoring device or intelligent display device, the space occupied by both is the aforementioned installation area.

[0050] To fully describe the structure and working principle of the cleaning device in the embodiments of this application, the embodiments of this application mainly take the simultaneous installation of intelligent monitoring equipment and intelligent display equipment as an example. In this case, the total space occupied by the intelligent monitoring equipment and the intelligent display equipment forms the aforementioned installation area. Of course, it should be understood that when actually installing intelligent monitoring equipment and intelligent display equipment, they can be set apart or set in the same area. It is understood that when set apart, cleaning devices can be configured separately, and when set in the same area, a set of cleaning devices can be set together. The following embodiments of this application mainly use the example of intelligent monitoring equipment and intelligent display equipment set in the same area to illustrate the structure and working principle of the cleaning device. It is understood that by appropriately adjusting the specific setting position of the cleaning device, the cleaning needs of separately installed intelligent monitoring equipment and intelligent display equipment can also be met by using the same cleaning device.

[0051] It should be noted that, in other cases, the cleaning device can also clean the surface or part of the B-pillar to ensure the B-pillar surface is dry and clean. Here, the surface and the installation area mentioned above are collectively referred to as the area to be cleaned. Therefore, the cleaning device in this embodiment can be used to clean the center pillar of a vehicle.

[0052] Based on the above-mentioned cleaning device, this application embodiment can also provide a vehicle, which can be an intelligent vehicle, and the cleaning device can clean the relevant equipment in the B-pillar area or the B-pillar area itself.

[0053] Figure 1 A schematic diagram of a stain removal device provided according to an embodiment of this application is shown; Figure 2 A schematic diagram of the installation of a spray structure 200 provided according to an embodiment of this application is shown.

[0054] In the embodiments of this application, please refer to Figure 1 and Figure 2 The cleaning device includes a spray structure 200.

[0055] The injection structure 200 can be installed on the center pillar 10 or in other parts of the vehicle. The injection structure 200 can be connected to the clean flow supply structure 100 in the following embodiments, and airflow and / or liquid flow can enter the injection structure 200 from the clean flow supply structure 100.

[0056] In some embodiments, the pipes in this application can be made of soft materials, such as rubber, so that the pipes can be easily installed in the vehicle. Based on the pipes' easy-to-bend nature, the pipes can bypass other structures in the vehicle to make full use of the vehicle's interior space, which is beneficial for the arrangement of the pipes.

[0057] The spray structure 200 has a nozzle 201 facing the area to be cleaned 11, which is located on the central column 10, and airflow and / or liquid flow can be sprayed from the nozzle 201 toward the area to be cleaned 11.

[0058] In some embodiments, please refer to Figure 1 The cleaning device may also include a cleaning flow supply structure 11, which is used to provide airflow and / or liquid flow. In some embodiments, the airflow may be dry air or the liquid flow may be water or the like. The cleaning flow supply structure 100 can direct the airflow and / or liquid flow to the jet structure 200.

[0059] It is understood that, in order to achieve the connection between the jet structure 200 and the clean flow supply structure 100, the jet structure 200 can be provided with pipe joints and other structures. The clean flow supply structure 100 and the jet structure 200 can be connected by a pipe. The pipe can be arranged separately, or the liquid supply pipe and / or gas pipe in the following embodiments can be used.

[0060] This application does not limit the specific type of the clean flow supply structure 100. For example, as can be seen from the following embodiments, the clean flow supply structure 100 may include at least one of a liquid supply structure 110 and a gas supply structure 120. The clean flow supply structure 100 may simply direct the airflow and / or liquid flow to the jet structure 200, and then use the power inside the jet structure 200 to eject the airflow and / or liquid flow to the decontamination device. The clean flow supply structure 100 may also be configured to not only direct the airflow and / or liquid flow to the jet structure 200, but also to generate power for the airflow and / or liquid flow to eject the airflow and / or liquid flow to the decontamination device.

[0061] The main function of the spray structure 200 in this embodiment is to spray airflow and / or liquid flow to the decontamination device. Therefore, the spray structure 200 can adopt the nozzle structure in related technologies, and the specific type of nozzle structure is not limited. Of course, in this embodiment, in order to fit the shape of the vehicle, the installation of the spray structure 200, or the shape of the area 11 to be cleaned, some structural changes have been made to the spray structure 200. See the following embodiments of the spray structure 200 for details.

[0062] After the airflow and / or liquid flow is ejected from the nozzle 201, the airflow and / or liquid flow can act on the area to be cleaned 11, and can clean the relevant surfaces of the central column 10. It can be understood that when the area to be cleaned 11 is equipped with intelligent monitoring equipment or intelligent display equipment, the airflow and / or liquid flow can clean these related equipment.

[0063] In this embodiment, the spray structure 200 can spray airflow and / or liquid flow toward the area 11 to be cleaned, thereby cleaning the center pillar 10 or related equipment installed on the center pillar 10. This can prevent the related equipment from being affected by contaminants, ensure the normal operation of the related equipment, and improve the driving safety of the vehicle to a certain extent.

[0064] In some embodiments, please refer to Figure 1 The clean flow supply structure 100 includes a liquid supply structure 110 for providing liquid flow. The liquid supply structure 110 includes a liquid tank 111 and a liquid passage 112 communicating with the liquid tank 111 and communicating with the jet structure 200.

[0065] The liquid tank 111 is a container structure for storing liquid. The specific structure and volume of the liquid tank 111 can be set according to the requirements. It is understood that in order to ensure a long-term supply of liquid, the volume of the liquid tank 111 can be relatively large, and in order to prevent the liquid tank 111 from occupying too much space, the volume of the liquid tank 111 can be relatively small.

[0066] In some specific embodiments, the liquid tank 111 can be independently installed on the vehicle, for example, it can be installed in the trunk, passenger compartment, or other locations. In other specific embodiments, the liquid tank 111 can also be formed as an inherent component of the vehicle; for example, the liquid tank 111 can include a water tank in the vehicle.

[0067] The aforementioned liquid pipeline 112 is one type of pipeline mentioned above, and it can be made of materials such as rubber. Of course, to improve the corrosion resistance and service life of the liquid pipeline 112, an anti-corrosion film can be added to the inner wall of the liquid pipeline 112.

[0068] In some embodiments, please refer to Figure 1 The liquid supply structure 110 also includes a liquid pump 113, which is installed on the liquid pipeline 112.

[0069] The liquid pump 113 is the power component in the liquid supply structure 110. The liquid pump 113 can draw liquid from the liquid tank 111 and make the liquid flow in the liquid supply pipeline to form a liquid flow.

[0070] As described above, the liquid supply structure 110 can cause the liquid to flow to the injection structure 200 through the liquid pump 113, and can also cause the liquid to be ejected from the injection structure 200.

[0071] In some embodiments, please refer to Figure 1 The liquid supply structure 110 also includes a first check valve 114, which is installed on the liquid pipeline 112 and can prevent liquid from flowing back into the liquid tank 111.

[0072] In some embodiments, please refer to Figure 1 The clean flow supply structure 100 also includes an air supply structure 120, which includes an air chamber 121 and an air passage 122 connected to the air chamber 121, and the air passage 122 is connected to the injection structure 200.

[0073] The gas chamber 121 is a box structure for storing gas. The specific structure and volume of the gas chamber 121 can be set according to the requirements. It is understood that in order to ensure a long-term supply of airflow, the volume of the gas chamber 121 can be relatively large, and in order to prevent the gas chamber 121 from occupying too much space, the volume of the gas chamber 121 can be relatively small.

[0074] In some specific embodiments, the air chamber 121 may be located in a suitable position on the vehicle, such as the trunk.

[0075] In some embodiments, the clean flow supply structure 100 may not have an air chamber 121, but may be composed of devices capable of generating airflow, such as blowers, axial flow fans, etc.

[0076] The aforementioned gas pipeline 122 is one type of pipeline mentioned above, and it can be made of materials such as rubber. Of course, to improve the corrosion resistance and service life of the gas pipeline 122, an anti-corrosion film can be added to the inner wall of the gas pipeline 122.

[0077] In some embodiments, please refer to Figure 1 The gas supply structure 120 also includes an air pump 123, which is installed on the gas pipeline 122 and is used to introduce gas into the gas chamber 121.

[0078] The air pump 123 can introduce gas into the air chamber 121 and form high pressure in the air chamber 121, thereby facilitating the ejection of gas from the injection structure 200.

[0079] In some specific embodiments, the air supply structure 120 may also include a solenoid valve 124, which may be installed on the air passage 122. By controlling the opening and closing of the solenoid valve 124, airflow can be allowed to enter the injection structure 200 or the airflow can be interrupted from entering the injection structure 200.

[0080] It is understandable that by installing a solenoid valve 124 on the air passage 122, the solenoid valve 124 can precisely control the flow of air. When air is introduced into the injection structure 200, the solenoid valve 124 needs to be opened so that the high-pressure gas in the air chamber 121 can enter the injection structure 200.

[0081] In some embodiments, please refer to Figure 1 The gas supply structure 120 may also include a second one-way valve 125, which is disposed on the gas pipeline 122 and can prevent gas from flowing back into the gas chamber 121.

[0082] In some embodiments, please refer to Figure 1 The decontamination device also includes a filter structure 300, and a filter structure can be installed on both the liquid pipeline 112 and the gas pipeline 122.

[0083] Specifically, the filter structure 300 includes a first filter structure 310 disposed on the liquid pipeline 112 and a second filter structure 320 disposed on the gas pipeline 122. The first filter structure 310 is used to filter the liquid flow, and the second filter structure 320 is used to filter the air flow.

[0084] The filter structure 300 can filter the liquid flow in the liquid pipeline 112 and the air flow in the air pipeline 122. After the liquid flow and air flow pass through the filter structure 300, impurities, oil stains and other contaminants in the liquid flow and air flow can be removed, so that the cleaner liquid flow and air flow can act on the area to be cleaned 11, thereby improving the cleaning effect.

[0085] The filter structure 300 may include cotton cloth, filter screen, etc. The specific structure of the filter screen is not limited, and it can be designed as a honeycomb structure with concave and convex shapes.

[0086] In the embodiments of this application, please refer to Figure 2 The spray structure 200 is disposed on the upper side of the area 11 to be cleaned, and / or disposed on the front side of the area 11 to be cleaned, and / or disposed on the edge of the central column 10 in the height direction. The above three arrangements will be described below through embodiments. It is understood that in other embodiments, the spray structure 200 may also be disposed in other positions.

[0087] It should be noted that the terms "upper side", "front side" and "height direction" mentioned above are descriptions of the vehicle's orientation when it is in a normal parked state. The upper side refers to the side facing the top of the vehicle, the front side refers to the side facing the front of the vehicle, and the rear side refers to the side facing the rear of the vehicle.

[0088] Figure 3 A schematic diagram of the installation of a spray structure 200 according to an embodiment of this application is shown at another angle; Figure 4 A schematic diagram showing another installation angle of a spray structure 200 provided according to an embodiment of this application is shown; Figure 5 An installation schematic diagram of another spray structure 200 provided according to an embodiment of this application is shown; Figure 6 An installation schematic diagram of another spray structure 200 provided according to an embodiment of this application is shown; Figure 7 It shows Figure 6 Top view of the central jet structure 200.

[0089] In some embodiments, please refer to Figures 2 to 4 The spray structure 200 is disposed on the upper side of the area to be cleaned 11 and the spray structure 200 includes a first housing 210, which is configured as an arc-shaped structure adapted to the edge of the area to be cleaned 11.

[0090] exist Figures 2 to 4 In the example shown, a camera 20 is installed in the area 11 to be cleaned. The area 11 to be cleaned is circular. To adapt to the circle, the first housing 210 is designed as an arc structure. On the one hand, this allows the first housing 210 to be structurally adapted to the area 11 to be cleaned, which can improve the appearance of the vehicle. On the other hand, it also helps the first housing 210 to structurally cover the area 11 to be cleaned, thereby improving the cleaning effect.

[0091] In other embodiments, the area to be cleaned 11 may also be a shape other than a circle. Correspondingly, the first housing 210 of the spray structure 200 may also be designed in other ways. For example, when the area to be cleaned 11 is rectangular, the first housing 210 may be located on the upper side of the area to be cleaned 11, and the first housing 210 may be a cuboid structure.

[0092] In some embodiments, please refer to Figure 5 The spray structure 200 is disposed on the front side of the area to be cleaned 11 and the spray structure 200 includes a second housing 220, the second housing 220 having a wind-breaking section 221 facing forward, the wind-breaking section 221 including at least one windward slope 221a for reducing wind resistance.

[0093] In the above embodiments, the wind-breaking slope of the wind-breaking section 221 can reduce wind resistance, enabling the vehicle to form a better flow line structure during driving, reducing the impact of wind resistance on the vehicle, and improving the vehicle's aerodynamic performance.

[0094] The dimension of the second housing 220 along the height direction can be larger than the dimension of the area 11 to be cleaned along the height direction, so that the spray structure 200 can cover the area 11 to be cleaned and achieve all-round cleaning of the area 11 to be cleaned.

[0095] In some specific embodiments, the air-breaking section 221 may include sharp corners, please refer to Figure 5 The wind-breaking section 221 has two windward inclined surfaces 221a, and the intersection of the two windward inclined surfaces 221a forms the aforementioned sharp angle.

[0096] In some embodiments, please refer to Figure 6 The central column 10 forms central column edges 12 on both sides along its height direction. The spray structure 200 is disposed at at least one central column edge 12 and the spray structure 200 includes a third housing 230, which is configured as a flat structure and covers the central column edge 12.

[0097] The injection structure 200 is positioned at the edge 12 of the center pillar, which can be combined with other vehicle designs to form a more stable connection structure. Specifically, the outer side of the center pillar edge 12 can usually be connected to the windshield. The center pillar edge 12 can be connected to the windshield by setting a limiting part or a limiting groove. Therefore, the housing is designed as a flat structure, which can be fitted into the aforementioned limiting part or limiting groove, so that the third housing 230 can be located between the windshield and the center pillar edge 12. This not only protects the center pillar 10 and the windshield, but also ensures a reliable connection of the third housing 230.

[0098] In some embodiments, please refer to Figure 7 The third housing 230 can be configured to include at least one inclined portion 231, which protrudes from the surface of the center pillar 10 in a direction away from the vehicle, thereby creating a larger contact area between the third housing 230 and the center pillar 10. The inclined portion 231 can also reduce the impact of wind resistance on the vehicle. A nozzle 201 is formed at the end of the inclined portion 231 facing the center pillar 10, allowing the nozzle 201 to be directed towards the area 11 to be cleaned.

[0099] In some specific embodiments, please refer to Figure 7 The third housing 230 includes two inclined portions 231, which generally form a triangular cross-section (the cross-section formed when viewed from the top of the vehicle to the bottom of the vehicle).

[0100] In some embodiments, the top of the vehicle protrudes from the central pillar 10 to form a protrusion (not shown in the figure), and the injection structure 200 can also be disposed on the protrusion. The injection structure 200 can be strip-shaped, wave-shaped, arc-shaped, etc., and the specific shape of the injection structure 200 can be set according to the requirements.

[0101] The above embodiments describe the external structure of the spray structure 200. The external structure of the spray structure 200 can be realized by the first housing 210, the second housing 220 and the third housing 230. These external structures can be comprehensively considered based on other factors such as the matching relationship between the spray structure 200 and the area to be cleaned 11, and the fitting relationship between the spray structure 200 and the vehicle.

[0102] In some embodiments, the nozzle 201 of the spray structure 200 is slit-shaped, thereby concentrating the airflow and / or liquid flow exiting the spray structure 200 and improving the rinsing effect of the airflow and / or liquid flow on the area 11 to be cleaned. For example, when the slit-shaped nozzle 201 is used in conjunction with the first housing 210, the airflow and / or liquid flow can rinse the area 11 to be cleaned from top to bottom, and the airflow and / or liquid flow can form an enveloping area that surrounds the area 11 to be cleaned, thereby improving cleaning efficiency and achieving high-efficiency cleaning. Furthermore, when the slit-shaped nozzle 201 is used in conjunction with the third housing 230, the airflow and / or liquid flow can be sprayed from the edge 12 of the central column towards the area 11 to be cleaned, resulting in a wide spray range.

[0103] In some embodiments, the spray structure 200 may include a plurality of nozzles 201, which may be distributed along a strip or along an arc. By employing a plurality of nozzles 201 and different distribution methods of the plurality of nozzles 201, different cleaning modes with different effects can be formed. For example, when the plurality of nozzles 201 are distributed along a strip, the spray structure 200 has a wider spray range and can adapt to the cleaning of a larger area 11 to be cleaned, achieving all-round cleaning of the area 11 to be cleaned. When the plurality of nozzles 201 are distributed along an arc, the spray structure 200 can better adapt to the shape of the area 11 to be cleaned, thereby achieving more efficient cleaning.

[0104] It is understandable that when multiple nozzles 201 are used, the shape of each nozzle 201 can be the same or different.

[0105] In some embodiments, the nozzle 201 can be designed with a small outer end and a large inner end. In other words, the nozzle 201 is a constricted structure, which allows airflow and / or liquid flow to be ejected quickly from the spray structure 200, thereby improving the cleaning ability of airflow and / or liquid flow.

[0106] In some embodiments, the spray structure 200 can be rotatably configured so that the spray angle can be adjusted as needed, thereby further improving the cleaning effect.

[0107] To enable the rotation of the injection structure 200, a drive structure can be installed at an appropriate location on the vehicle. This drive structure can be a universal joint, a combination of gears and racks, a combination of cams and racks, a rotary motor, or other structures. The injection structure 200 can be installed at the output end of the drive structure, allowing the injection structure 200 to rotate within a certain range.

[0108] In some embodiments, the cleaning device further includes a dirt detection structure for detecting the contamination status in the area 11 to be cleaned. The dirt detection structure includes at least one of an optical camera 20, an infrared sensor, a pressure sensor, and a capacitive sensor.

[0109] Among them, the optical camera 20 can determine the type and degree of pollution through image recognition and analysis. The infrared sensor can detect changes in the reflectivity of the pollutant surface, thereby determining the thickness of the pollutant. The pressure sensor can determine changes in the mass of the pollutant through changes in pressure. The capacitive sensor can determine changes in the mass of the pollutant through changes in resistance.

[0110] In some embodiments, the decontamination device further includes a control structure connected to the dirt detection structure and the clean flow supply structure 100. The control structure is used to turn the clean flow supply structure 100 on or off according to the detection result of the dirt detection structure.

[0111] This control structure is the core of the decontamination device, and it can control the decontamination device to achieve automatic cleaning.

[0112] For ease of understanding and simplification, the clean flow supply structure 100, which includes a liquid supply structure 110 and a gas supply structure 120, with the liquid supply structure 110 including a liquid pump 113 and the gas supply structure 120 including a gas pump 123, will be used as an example. In this case, the control process of the above control structure is roughly as follows:

[0113] Contamination detection phase: The contamination detection structure continuously monitors the contamination status of the area to be cleaned, 11;

[0114] Signal processing stage: The control structure receives the detection results monitored by the dirt detection structure and determines whether the pollution level exceeds the set threshold.

[0115] Decontamination start-up phase: If the predetermined threshold is exceeded, the control structure controls the air pump 123 and / or liquid pump 113 to start;

[0116] Spray cleaning stage: Airflow and / or liquid flow are sprayed from nozzle 201 to clean the area 11 to be cleaned;

[0117] Dynamic adjustment stage (optional): If a rotating spray structure 200 is used, the control structure can also control the rotation of the spray structure 200 to improve cleaning efficiency and cleaning effect;

[0118] Decontamination completion stage: When the contamination level is below the predetermined threshold, the control structure shuts down the air pump 123 and the liquid pump 113, ending the cleaning process.

[0119] As can be seen from the above cleaning process, by setting up a control structure and a contamination detection structure, the decontamination device in this embodiment can achieve automatic cleaning.

[0120] As can be seen from the above cleaning process, by reasonably setting the rotatable spray structure 200 and by reasonably designing the nozzle structure and its nozzle 201, it is possible to achieve all-round cleaning of the area 11 to be cleaned.

[0121] As can be seen from the above cleaning process, when the pollution level is below the predetermined threshold, the cleaning process can be stopped to avoid wasting airflow and / or liquid flow.

[0122] As can be seen from the above cleaning process, different cleaning modes can be formed by reasonably selecting airflow and liquid flow, as well as by reasonably matching the ratio of airflow and liquid flow, which can be adapted to different types of pollutants.
