Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] The existing vehicle, especially the SUV, has a significant gap in the tail shape. During driving, the high-speed airflow forms a negative pressure effect at the tail door, which easily rolls back some impurities and dust and sticks them on the tail door glass. The rear window full of dust will affect the driver's observation of the rear road conditions through the interior rearview mirror, which is not conducive to safe driving. At the same time, it also affects the overall appearance. However, the existing SUV vehicle usually uses a traditional single wiper for cleaning. The rear wiper is installed on the tail door, which is relatively conspicuous and affects the overall appearance of the car. Moreover, the cleaning range of the rear wiper is limited to a partial sector, thus limiting the field of view of the interior rearview mirror; in addition, the wiper rubber strip is prone to aging, resulting in reduced cleaning effect and frequent replacement, as well as the situation that the wiper cannot be used in winter.

[0025] Therefore, a cleaning device is proposed in the present application to replace the existing single wiper to clean the rear window of the vehicle.

[0026] The cleaning device in the present application can be applied to related structures of vehicles, rail transit, or industrial equipment. In the present application, the cleaning device is applied to a vehicle as an example for illustration, especially for cleaning the rear window of an SUV vehicle.

[0027] Please refer to Figures 1 to 2 , Figure 1 is a perspective structural schematic diagram of an embodiment of the cleaning device of the present application; Figure 2 is a partial structural schematic diagram of an embodiment of the cleaning device of the present application.

[0028] In one aspect of the present application, a cleaning device 10 is provided. The cleaning device 10 is used in a vehicle (not shown in the figure). The vehicle includes a vehicle body (not shown in the figure), a windshield 22, and the cleaning device 10. The cleaning device 10 includes an air compression assembly 11, a first pipeline 12, and a spray brush assembly 13. The air compression assembly 11 is configured to be arranged on the vehicle body, and the air compression assembly 11 is used to form a high-pressure airflow; the first pipeline 12 is configured to be arranged on the vehicle body, and one end of the first pipeline 12 is connected to the air compression assembly 11; the spray brush assembly 13 is arranged on the windshield 22, and the spray brush assembly 13 is connected to the other end of the first pipeline 12; the spray brush assembly 13 includes a plurality of nozzles 131, and the plurality of nozzles 131 are in communication with the first pipeline 12 to spray the high-pressure airflow on the windshield 22; wherein, along the spraying direction of the high-pressure airflow, the nozzles 131 gradually increase in size along the extension direction of the first pipeline 12.

[0029] From the above structure, the air compression assembly 11 can form a high-pressure airflow, deliver the high-pressure airflow to the nozzle 131 through the first pipeline 12, and finally spray the high-pressure airflow through the nozzle 131 to flush the windshield 22. Therefore, compared with the prior art using a single wiper, the application sprays high-pressure airflow through the nozzle 131 to realize the flushing of the windshield 22. On the one hand, it can effectively clean the windshield 22, thereby reducing the limited range of the field of view of the rearview mirror in the vehicle, and thus improving the safety of driving. On the other hand, since the single wiper cannot be used normally in extremely cold weather, the cleaning device 10 of the application sprays high-pressure airflow through the nozzle 131, which is not affected by extreme weather, so as not to affect the field of view of the rearview mirror in the vehicle in extreme weather, thereby improving the safety of driving.

[0030] Further, along the spraying direction of the high-pressure airflow, the size of the nozzle 131 along the extension direction of the first pipeline 12 gradually increases. Therefore, along the spraying direction of the high-pressure airflow, the nozzle 131 can be in a diffusion shape. Compared with the converging shape of the nozzle 131 away from the vehicle, on the one hand, the application can increase the coverage area when the high-pressure airflow is sprayed, thereby further expanding the cleaning range of a single nozzle 131 to improve the cleaning efficiency. On the other hand, since the cleaning range of a single nozzle 131 is increased, the effective cleaning of the windshield 22 can be realized by a small number of nozzles 131, thereby reducing the number of nozzles 131 used to reduce production costs. In addition, it can also indirectly improve the field of view of the rearview mirror in the vehicle, thereby improving the safety of driving and improving the driving experience of the user.

[0031] Among them, the number of nozzles 131 can be 2, 4, 5, 7, 8, 9, 11, etc., which is not limited here and can be adjusted adaptively according to the specific vehicle model.

[0032] Among them, the spraying direction of the nozzle 131 is towards the windshield 22, so that the high-pressure airflow sprayed from the nozzle 131 can be sprayed on the windshield 22, thereby realizing the effective cleaning of the windshield 22 to reduce the limited range of the field of view of the rearview mirror in the vehicle and improve the safety of driving.

[0033] The nozzles 131 can be arranged at intervals along the extension direction of the first pipeline 12, thereby improving the cleaning range of the nozzles 131 and improving the cleaning efficiency.

[0034] Among them, the air compression assembly 11 can be controlled by hardware alone to generate and store high-pressure airflow, or the air compression assembly 11 can be embedded in the chassis air suspension system of the vehicle body and share hardware with the chassis air suspension system for control, thereby reducing production costs. This is not limited here.

[0035] Please refer to Figure 1 and Figure 2 , refer to Figure 3 , Figure 3 is a structural schematic view of a spray brush assembly of an embodiment of the cleaning device.

[0036] In some embodiments of the present application, the spray brush assembly 13 further comprises a high-pressure air rail 132, which is arranged above the windshield 22 and is in communication with the first pipeline 12 and the nozzle 131 respectively. Since the first pipeline 12 usually has a certain flexibility, when the high-pressure airflow flows in the first pipeline 12, the stability of the first pipeline 12 is poor, therefore, in the present application, the high-pressure air rail 132 is arranged above the windshield 22, so as to play a certain fixing and supporting role for the first pipeline 12, so as to reduce the shaking and deformation of the first pipeline 12, improve the stability of the high-pressure airflow transmission, and further improve the reliability of the cleaning device 10. In addition, compared with the direct connection through the first pipeline 12 and the nozzle 131, the arrangement of the high-pressure air rail 132 can also well reduce the aging and wear of the first pipeline 12, so as to avoid the loosening and air leakage, and further improve the service life and reliability of the cleaning device 10.

[0037] Further, the inner diameter of the nozzle 131 away from the high-pressure air rail 132 is greater than that of the end connected with the high-pressure air rail 132. Therefore, in the process of spraying, the spraying range of the high-pressure airflow is larger, so as to expand the cleaning range of the nozzle 131, so as to improve the cleaning efficiency. In addition, since the cleaning range of a single nozzle 131 is increased, the effective cleaning of the windshield 22 can be realized by a small number of nozzles 131, so as to reduce the number of nozzles 131, so as to reduce the production cost. In addition, the field of view of the vehicle interior rearview mirror can also be indirectly improved, so as to improve the driving safety and improve the driving experience of the user.

[0038] Wherein, the coverage angle of the high-pressure airflow sprayed by the nozzle 131 can be set according to the size of the actual application vehicle and the number of nozzles 131, which is not limited here.

[0039] In some embodiments of the present application, the plurality of nozzles 131 are arranged on the same side of the high-pressure air rail 132, so that the plurality of nozzles 131 can all clean the windshield 22, thereby effectively improving the cleaning efficiency. In the vertical direction of the extension direction of the high-pressure air rail 132, the height of the nozzles 131 gradually decreases, so that the nozzles 131 present a gradually closed shape. This arrangement can extrude the high-pressure air flow at the output end of the nozzles 131, which can effectively enhance the air flow intensity when the high-pressure air flow is ejected, thereby effectively improving the cleaning efficiency; on the other hand, it can increase the coverage area of the high-pressure air flow, thereby expanding the cleaning range of the nozzles 131.

[0040] In some embodiments of the present application, the spray brush assembly 13 further comprises a plurality of connecting pipes 133 connected between the nozzles 131 and the high-pressure air rail 132, and the connecting pipes 133 are in communication with the high-pressure air rail 132 and the nozzles 131. In the present application, the connecting pipes 133 are arranged to connect the high-pressure air rail 132 and the nozzles 131, which can improve the connection stability between the nozzles 131 and the high-pressure air rail 132, thereby improving the reliability of the structure; on the other hand, the connecting pipes 133 enable the nozzles 131 and the high-pressure air rail 132 to be designed to be separable, which can facilitate the installation and replacement of the nozzles 131, especially when replacement is needed, without replacing the entire high-pressure air rail 132, thereby saving maintenance costs and improving user experience.

[0041] Alternatively, the nozzles 131 can be directly connected to the high-pressure air rail 132 by welding, which is not limited here.

[0042] Please continue to refer to Figure 1 In some embodiments of the present application, the vehicle further comprises a water tank (not shown in the figure) arranged in the vehicle body; the cleaning device 10 further comprises a second pipeline 14, one end of which is connected to the water tank, and the other end is connected to the first pipeline 12 through a first valve body 141; wherein when the first valve body 141 is opened, the liquid in the water tank and the high-pressure air flow can be mixed and flow into the high-pressure air rail 132 at the connection between the first pipeline 12 and the second pipeline 14, and then sprayed through the nozzles 131. Thus, when the first valve body 141 is opened, the water in the water tank can flow into the first pipeline 12 through the second pipeline 14, and then flow into the high-pressure air rail 132 after being mixed with the high-pressure air flow from the first pipeline 12, and finally spray the liquid and high-pressure air flow through the nozzles 131. Therefore, by arranging the second pipeline 14 and the water tank, when there are stubborn stains on the windshield 22, the liquid and high-pressure air flow can be selected to be sprayed at the same time to clean the windshield 22, thereby better improving the cleanliness of the windshield 22.

[0043] Wherein, the user can select the opening or closing of the first valve body 141 according to the need, when the first valve body 141 is closed, the nozzle 131 only sprays high pressure airflow to clean the windshield 22. When the first valve body 141 is opened, the nozzle 131 sprays high pressure airflow and liquid at the same time to clean the windshield 22.

[0044] Wherein, the water tank can be a water tank for passenger glass water in the chassis, or also can be a water tank for the cleaning device 10 alone, which is not limited here. The liquid in the water tank can be glass water, or also can be pure water, which is not limited here.

[0045] In some embodiments of the present application, the vehicle includes a vehicle body frame beam 21, and the air compression assembly 11 includes an air compression pump 111, a high pressure gas storage tank 112 and a third pipeline 16. Wherein, the air compression pump 111 is arranged on the vehicle body frame beam 21; the high pressure gas storage tank 112 is arranged on the vehicle body frame beam 21, and the third pipeline 16 is communicated with the air compression pump 111 at one end and communicated with the high pressure gas storage tank 112 at the other end; wherein, the third pipeline 16 is used for transmitting high pressure airflow from the air compression pump 111 to the high pressure gas storage tank 112, and the high pressure gas storage tank 112 is used for storing the high pressure airflow generated by the air compression pump 111 and transmitting the high pressure airflow to the nozzle 131 through the first pipeline 12. Specifically, the air compression pump 111 can be used to generate high pressure airflow, the high pressure airflow generated by the air compression pump 111 can be input to the high pressure gas storage tank 112 through the third pipeline 16, and the high pressure gas storage tank 112 can store the high pressure airflow and deliver it to the high pressure gas rail 132 through the first pipeline 12, and finally output from the nozzle 131. By arranging the air compression pump 111, the high pressure gas storage tank 112 and the third pipeline 16, a stable and continuous air source can be provided for the cleaning device 10, so as to ensure the cleaning efficiency and stability of the cleaning process of the cleaning device 10.

[0046] The structure of the vehicle body frame beam 21 can provide installation space for the arrangement of the air compression pump 111 and the high pressure gas storage tank 112, thereby facilitating the installation of the air compression pump 111 and the high pressure gas storage tank 112. Moreover, through the vehicle body frame beam 21, the air pump and the high pressure gas storage tank 112 can be embedded into the chassis air suspension system and share hardware and control with the chassis air suspension system, thereby effectively reducing the production cost of the cleaning device 10.

[0047] Wherein, in some other embodiments, the air compression pump 111 and the high pressure gas storage tank 112 can also not be embedded into the chassis air suspension system, at which time the air compression pump 111 and the high pressure gas storage tank 112 can be controlled separately, which is not limited here.

[0048] In some embodiments of the present application, the air compression assembly 11 further comprises a second valve body 113, which is arranged at the high-pressure gas tank 112 and at the connection between the high-pressure gas tank 112 and the first pipeline 12. The second valve body 113 is used to control the opening and closing of the high-pressure gas tank 112. By arranging the second valve body 113, the opening and closing of the high-pressure gas tank 112 can be controlled. Specifically, when the second valve body 113 is opened, high-pressure gas flow can flow from the high-pressure gas tank 112 to the first pipeline 12, and then to the high-pressure gas rail 132, and finally be sprayed from the nozzle 131. Therefore, the arrangement of the second valve body 113 can facilitate the user to control whether the windshield 22 needs to be cleaned according to the needs, which can save energy on the one hand, such as saving oil for oil cars or saving electricity for new energy cars, and on the other hand, can better improve the user's control feeling.

[0049] When the second valve body 113 is opened, the user can choose to open or close the first valve body 141 according to the needs. When the first valve body 141 is also opened, the gas-liquid mixture can be sprayed from the nozzle 131, and when the first valve body 141 is closed, only high-pressure gas flow can be sprayed. When the second valve body 113 is closed, the user can choose to open or close the first valve body 141 according to the needs. When the first valve body 141 is closed, the cleaning device 10 does not work, and when the first valve body 141 is opened, liquid can be sprayed from the nozzle 131 to clean the windshield 22.

[0050] In some embodiments of the present application, in order to reduce the vibration of the air compression assembly 11, the cleaning device 10 further comprises a shock isolation pad 15. The shock isolation pad 15 is arranged between the vehicle body frame beam 21 and the air compression assembly 11. The shock isolation pad 15 can be used to reduce the vibration of the air compression assembly 11, thereby effectively reducing the influence of the vibration of the air compression assembly 11 on the vehicle body frame beam 21 during operation, and thereby improving the service life of the vehicle body frame beam 21.

[0051] Please continue to refer to Figure 1 The second aspect of the present application provides a vehicle, which comprises a vehicle body, a windshield 22 and a cleaning device 10. The windshield 22 is arranged on the vehicle body, and the cleaning device 10 is arranged in the vehicle body to clean the windshield 22. In the present application, compared with the single wiper in the prior art, the high-pressure gas flow sprayed from the nozzle 131 of the cleaning device 10 is used to realize the flushing of the windshield 22. On the one hand, the windshield 22 can be effectively cleaned, thereby reducing the limited range of the field of view of the rearview mirror in the vehicle, and thereby improving the safety of using the vehicle. On the other hand, since the single wiper cannot be used normally in extreme cold weather, the cleaning device 10 of the present application sprays high-pressure gas flow through the nozzle 131, which is not affected by extreme weather, thereby not affecting the field of view of the rearview mirror in the vehicle in extreme weather, and thereby improving the safety of using the vehicle.

[0052] Further, in the direction of the jet of the high-pressure airflow, the size of the nozzle 131 in the direction of extension of the first pipeline 12 gradually increases. Therefore, in the direction of the jet of the high-pressure airflow, the nozzle 131 can be in a diverging shape, which can increase the coverage area of the high-pressure airflow when jetted, thereby further expanding the cleaning range of a single nozzle 131 to improve the cleaning efficiency. On the other hand, since the cleaning range of a single nozzle 131 is increased, the effective cleaning of the windshield 22 can be achieved by a small number of nozzles 131, thereby reducing the number of nozzles 131 used to reduce production costs. In addition, the field of view of the rearview mirror in the vehicle can also be indirectly improved, thereby improving the driving safety and improving the driving experience of the user.

[0053] In another embodiment of the present application, the vehicle body is outwardly convex in the direction of the windshield 22 to form a spoiler 23, and the cleaning device 10 comprises a high-pressure air rail 132 which is hidden inside the spoiler 23. The spoiler 23 can guide the airflow, so that the airflow jetted by the nozzle 131 can be jetted on the windshield 22 under the guidance of the spoiler 23, thereby improving the cleaning effect of the cleaning device 10 to ensure the clarity of the field of view of the rearview mirror in the vehicle and improve the driving experience of the user. The high-pressure air rail 132 is hidden inside the spoiler 23, which can avoid the exposure of the nozzle 131 and the high-pressure air rail 132 on the windshield 22, thereby improving the overall aesthetics of the vehicle 20. On the other hand, when the nozzle 131 sprays liquid, the liquid can also flow downward along the windshield 22 under the action of its own gravity, thereby saving energy and improving the driving experience of the user.

[0054] In the embodiment of the present application, the high-pressure air rail 132 is arranged above the windshield 22, which can facilitate the hiding of the high-pressure air rail 132 inside the spoiler 23. Of course, in some other embodiments, the high-pressure air rail 132 can also not be arranged above the windshield 22, which is not limited here.
