Specifically, the nozzle is positioned towards the camera, and the air generated by the pump passes through the nozzle, blowing away dust or dirt. However, for some stubborn stains, relying solely on air cleaning is insufficient and has certain limitations. Utility Model Content To address the aforementioned technical problems, this utility model provides a user-friendly vehicle-mounted camera cleaning system and vehicle, which achieves better cleaning results.

[0004] The technical problem solved by this utility model embodiment is addressed by the following technical solution: A vehicle-mounted camera cleaning system includes a high-pressure air source, a control valve module, a first fluid line, a second fluid line, a third fluid line, a liquid reservoir, and at least one nozzle for spraying fluid toward the vehicle-mounted camera. The liquid reservoir includes a liquid storage space and a gas space connected in communication. The output end of the high-pressure air source is connected to the inlet of the control valve module.

[0019] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1-2 As shown, one embodiment of this application provides a vehicle camera cleaning system 1, including a high-pressure air source 2, a control valve module 3, a first fluid line 4, a second fluid line 5, a third fluid line 6, a liquid storage tank 7, and at least one nozzle 8 for spraying fluid toward the vehicle camera. The liquid storage tank 7 includes a liquid storage space 71 and a gas space 72 connected in series. The output end of the high-pressure air source 2 is connected to the inlet of the control valve module 3. The first outlet of the control valve module 3 is connected to the fluid inlet of the nozzle 8 through the first fluid line 4. The second outlet of the control valve module 3 is connected to the gas space 72 through the second fluid line 5. One end of the third fluid line 6 is connected to the liquid storage space 71, and the other end of the third fluid line 6 is connected to the fluid inlet of the nozzle 8. The control valve module 3 is used to control the high-pressure air source 2 to connect to the first fluid line 4 through the first outlet and to control the high-pressure air source 2 to connect to the second fluid line 5 through the second outlet. The high-pressure air source referred to in this embodiment generally refers to a centralized air source in the vehicle that can provide a pump with a high gas pressure and can output / provide a continuous airflow with a gauge pressure higher than 100 kPa.

[0021] In normal operation, when the camera detects a need for cleaning, the control valve module 3 opens, connecting the high-pressure air source 2 to the first fluid line 4. This allows the gas supplied by the high-pressure air source 2 to directly blow high-pressure gas onto the vehicle camera through the nozzle 8, handling most cleaning scenarios. When the camera detects stubborn stains, direct blowing gas is insufficient to remove them. In this case, the control valve module 3 controls the high-pressure air source 2 to connect to the second fluid line 5 through the second outlet. High-pressure gas is then introduced into the sealed liquid storage tank 7, causing a sudden increase in pressure in the gas space 72 of the tank. The liquid in the tank 7 is then pumped out through the third fluid line 6 and enters the nozzle 8, whereby the nozzle 8 sprays liquid onto the camera for cleaning. After a period of liquid spraying, the stains are removed. The control valve module 3 then controls the high-pressure air source 2 to connect to the first fluid line 4 through the first outlet, entering the air-blowing cleaning mode. After the nozzle 8 blows away any remaining droplets, the droplets on the camera surface are dried without affecting the normal operation of the vehicle camera. The vehicle camera cleaning system 1 of this embodiment can clean the vehicle camera not only by blowing air, but also by liquid spraying. This improves both the cleaning effect and efficiency. Furthermore, the control valve module 3 can switch the fluid supplied by the same high-pressure air source 2 to either the first fluid pipeline 4 or the second fluid pipeline 5, which facilitates the switching of cleaning methods and avoids the need for multiple high-pressure air sources 2. This simplifies the structure of the vehicle camera cleaning system 1 and makes it more convenient to use.

[0022] It should be noted that the liquid storage tank 7 is equipped with a safe liquid level line. The liquid stored in the liquid storage tank 7 must not exceed this level line, so as to reserve enough space to fill the liquid supplied by the high-pressure gas source 2.

[0023] In some embodiments, such as Figure 1-2 As shown, the high-pressure gas source 2 includes an air pump 21 and an air storage tank 22. The air pump 21 is connected to the input end of the air storage tank 22, and the output end of the air storage tank 22 is connected to the input end of the control valve module 3. The air pump 21 is used to draw in outside air and store it in the air storage tank 22. The air storage tank 22 supplies gas to the first fluid pipeline 4 or the second fluid pipeline 5 through the control valve module 3.

[0024] In some embodiments, such as Figure 1-2 As shown, the high-pressure air source 2 also includes an air filter 23, which is connected to the air pump 21. The air filter 23 reduces the impurities and liquids contained in the gas drawn by the air pump 21, which helps the air pump 21 provide clean gas to the air storage tank 22.

[0025] In some embodiments, such as Figure 1-2As shown, the high-pressure gas source 2 also includes a safety valve 24, which is connected to the gas storage tank 22. The safety valve 24 is used to prevent pressure release when the gas pressure in the gas storage tank 22 exceeds the threshold, thus preventing excessive gas from being stored in the gas storage tank 22.

[0026] In some embodiments, such as Figure 1-2 As shown, the high-pressure gas source 2 also includes a pressure regulating valve 25. The input end of the pressure regulating valve 25 is connected to the gas storage tank 22, and the output end of the pressure regulating valve 25 is connected to the input end of the control valve module 3. The pressure regulating valve 25 is used to regulate the gas pressure output from the gas storage tank 22. In this embodiment, in order to ensure that the gas output from the pressure regulating valve 25 is unidirectionally output, a one-way valve 26 is provided between the pressure regulating valve 25 and the control valve module 3.

[0027] In some embodiments, such as Figure 2 As shown, the high-pressure air source 2 also includes a main distribution valve 27, which is connected between the air tank 22 and the pressure regulating valve 25. The main distribution valve 27 is used to distribute the gas delivered by the air tank 22 into multiple air paths for delivery. It is understandable that when there are multiple vehicle-mounted cameras, each camera can be configured with a corresponding cleaning air path as needed. Each cleaning air path is equipped with structures corresponding to both air blowing cleaning and liquid jet cleaning methods. Using the main distribution valve 27, gas can be supplied to multiple cleaning air paths separately, facilitating management and simplifying the structure of the vehicle-mounted camera cleaning system 1.

[0028] In some embodiments, such as Figure 1-2 As shown, the control valve module 3 includes a main control valve 31 and a reversing valve 32. One end of the main control valve 31 is connected to the output end of the high-pressure air source 2, and the other end is connected to the inlet of the reversing valve 32. The first outlet of the reversing valve 32 is connected to the fluid inlet of the nozzle 8 through the first fluid pipeline 4, and the second outlet of the reversing valve 32 is connected to the gas space 72 through the second fluid pipeline 5. The main control valve 31 is used to connect or disconnect the high-pressure air source 2 and the reversing valve 32. That is, when the main control valve 31 is in the connected state, the gas supplied by the high-pressure air source 2 can be delivered to the reversing valve 32 through the main control valve 31, and the gas will be delivered to the first fluid pipeline 4 or the second fluid pipeline 5 under the action of the reversing valve 32, so as to perform air blowing cleaning or liquid spray cleaning of the vehicle camera. When the main control valve 31 is in the disconnected state, the gas supplied by the high-pressure air source 2 cannot be delivered to the reversing valve 32 through the main control valve 31.

[0029] In some embodiments, such as Figure 1-2As shown, the first fluid line 4 is equipped with a gas control valve 41, which is connected between the control valve module 3 and the nozzle 8. The gas control valve 41 is used to control the flow rate of gas in the first fluid line 4. Thus, under the adjustment of the gas control valve 41, the gas output from the nozzle 8 towards the vehicle-mounted camera can be adjusted to provide different blowing forces to the dirt on the surface of the vehicle-mounted camera, thereby achieving the cleaning purpose. In this embodiment, the gas control valve 41 is a throttle valve.

[0030] In some embodiments, such as Figure 1-2 As shown, the first fluid pipeline 4 is also provided with a first check valve 42. The first check valve 42 is connected between the gas control valve 41 and the nozzle 8, which is conducive to guiding the gas to flow along the first fluid pipeline 4 and preventing the gas from flowing back along the first fluid pipeline 4.

[0031] In some embodiments, such as Figure 1-2 As shown, the first fluid line 4 also includes an air dryer 43, which is disposed between the first one-way valve 42 and the gas control valve 41. The air dryer 43 dries the gas, ensuring that the gas supplied from the first one-way valve 42 to the nozzle 8 is dry. This prevents the gas blown towards the vehicle camera from becoming humid and causing the camera to be obscured by moisture, thus ensuring the cleaning effect of the gas.

[0032] In some embodiments, such as Figure 1-2 As shown, the second fluid line 5 is equipped with a liquid control valve 51, which is connected between the control valve module 3 and the storage tank 7. The liquid control valve 51 is used to control the flow rate of the gas flowing in the second fluid line 5 to regulate the flow rate of the liquid in the third fluid line 6. Under the action of the liquid control valve 51, the flow rate of the gas entering the gas space 72 can be adjusted to indirectly regulate the rate of increase of the gas pressure in the storage tank 7, thereby indirectly regulating the rate at which the liquid in the storage tank 7 is squeezed out. In this embodiment, the liquid control valve 51 is a throttle valve.

[0033] In other embodiments, such as Figure 1-2 As shown, the third fluid line 6 is equipped with a liquid control valve 51, which is connected between the liquid storage tank 7 and the nozzle 8. The liquid control valve 51 is used to control the flow rate of the liquid in the third fluid line 6. Under the action of the liquid control valve 51, the flow rate of the liquid flowing in the third fluid line 6 can be directly adjusted, indirectly changing the impact force of the liquid sprayed from the nozzle 8 to achieve different cleaning effects.

[0034] In some embodiments, such as Figure 1-2As shown, the third fluid line 6 also includes a second check valve 61, which is located between the nozzle 8 and the storage tank 7. Under the action of the second check valve 61, the risk of liquid flowing back to the storage tank 7 along the third fluid line 6 is avoided, which is conducive to the unidirectional flow of liquid along the third fluid line 6.

[0035] Understandably, the number of nozzles 8 can be set as needed. For example, the number of nozzles 8 can be one, two, or more, depending on the specific requirements. When there is only one nozzle 8, the output ends of the first fluid line 4 and the third fluid line 6 are both connected to the fluid inlet of the same nozzle 8. When there are two or more nozzles 8, the first fluid line 4 and the third fluid line 6 are each connected to at least one nozzle 8, and the fluids transported by the first fluid line 4 and the third fluid line 6 can be ejected from different nozzles 8. In use, multiple nozzles 8 can be set on different sides of the vehicle camera to facilitate cleaning of the vehicle camera from multiple locations. In some embodiments, such as Figure 2 As shown, the first fluid line 4 also includes a first distribution valve 44, which is disposed between the plurality of nozzles 8 and the control valve module 3. The first distribution valve 44 is used to distribute the gas transported along the first fluid line 4 to the fluid outlets of the plurality of nozzles 8. In this way, under the action of the first distribution valve 44, the gas transported along the first fluid line 4 can be distributed, so that the gas can be sprayed out simultaneously from the plurality of nozzles 8 located at different positions of the vehicle camera, thereby achieving a better cleaning effect.

[0036] In some embodiments, such as Figure 2 As shown, the third fluid line 6 also includes a second distribution valve 62, which is disposed between the plurality of nozzles 8 and the liquid storage tank 7. The second distribution valve 62 is used to distribute the liquid transported along the third fluid line 6 to the fluid outlets of the plurality of nozzles 8. In this way, under the action of the second distribution valve 62, the liquid transported along the third fluid line 6 can be distributed, so that the liquid can be sprayed out simultaneously from the plurality of nozzles 8 located at different positions of the vehicle-mounted camera, thereby achieving a better cleaning effect.

[0037] In some embodiments, such as Figure 2 As shown, the vehicle-mounted camera cleaning system 1 also includes a first pressure gauge 9, which is located between the high-pressure air source 2 and the control valve module 3. The first pressure gauge 9 is used to measure the air pressure of the gas flowing from the high-pressure air source 2 to the control valve module 3. The first pressure gauge 9 allows users to directly observe whether the high-pressure air source 2 is working properly and supplying gas.

[0038] In some embodiments, such as Figure 2As shown, the vehicle-mounted camera cleaning system 1 also includes a second pressure gauge 10, which is installed in the first fluid line 4. The second pressure gauge 10 is used to measure the pressure of the gas flowing into the first fluid line 4. The second pressure gauge 10 facilitates direct observation by the user to see if there is gas flowing into the first fluid line 4 and to troubleshoot any malfunctions.

[0039] In some embodiments, such as Figure 2 As shown, the vehicle-mounted camera cleaning system 1 also includes a third pressure gauge 11, which is installed in the second fluid line 5. The third pressure gauge 11 is used to measure the pressure of the gas flowing into the second fluid line 5. The third pressure gauge 11 facilitates direct observation by the user to see if there is gas flowing into the second fluid line 5 and to troubleshoot any malfunctions.

[0040] In some embodiments, such as Figure 2 As shown, the vehicle-mounted camera cleaning system 1 also includes an energy accumulator 12, which is connected between the high-pressure air source 2 and the control valve module 3. The energy accumulator 12 can convert the energy in the vehicle-mounted camera cleaning system 1 into compressed energy or potential energy for storage at appropriate times. When the vehicle-mounted camera cleaning system 1 needs sufficient air pressure, it can convert the compressed energy or potential energy back into air pressure for release, replenishing the system. When the air pressure in the vehicle-mounted camera cleaning system 1 increases instantaneously, it can absorb this energy to ensure the overall system pressure remains normal.

[0041] In some embodiments, the vehicle camera cleaning system 1 further includes a heater (not shown) and a temperature sensor. Both the heater and the temperature sensor are disposed within the liquid storage space 71 of the liquid reservoir 7. The temperature sensor is used to sense the temperature of the liquid in the liquid reservoir 7, and the heater is used to heat the liquid in the liquid reservoir 7. Thus, when the ambient temperature is too low, the heater can be controlled to heat the liquid in the liquid reservoir 7, so that a higher temperature liquid can be sprayed when the nozzle 8 sprays liquid onto the vehicle camera, preventing the liquid sprayed onto the vehicle camera from freezing due to low temperature.

[0042] The vehicle camera cleaning system 1 provided in this application embodiment includes a high-pressure air source 2, a control valve module 3, a first fluid pipeline 4, a second fluid pipeline 5, a third fluid pipeline 6, a liquid storage tank 7, and at least one nozzle 8 for spraying fluid toward the vehicle camera. The liquid storage tank 7 includes a liquid storage space 71 and a gas space 72 that are connected to each other. The output end of the high-pressure air source 2 is connected to the inlet of the control valve module 3. The first outlet of the control valve module 3 is connected to the fluid inlet of the nozzle 8 through the first fluid pipeline 4. The second outlet of the control valve module 3 is connected to the gas space 72 through the second fluid pipeline 5. One end of the third fluid pipeline 6 is connected to the liquid storage space 71, and the other end of the third fluid pipeline 6 is connected to the fluid inlet of the nozzle 8. The control valve module 3 is used to control the high-pressure air source 2 to connect to the first fluid pipeline 4 through the first outlet and to control the high-pressure air source 2 to connect to the second fluid pipeline 5 through the second outlet. The vehicle camera cleaning system 1 of this embodiment can clean the vehicle camera not only by blowing air, but also by liquid spraying. This improves both the cleaning effect and efficiency. Furthermore, the control valve module 3 can switch the fluid supplied by the same high-pressure air source 2 to either the first fluid pipeline 4 or the second fluid pipeline 5, which facilitates the switching of cleaning methods and avoids the need for multiple high-pressure air sources 2. This simplifies the structure of the vehicle camera cleaning system 1 and makes it more convenient to use.

[0043] Another embodiment of this application provides a vehicle including the vehicle-mounted camera cleaning system 1 in the above embodiment and a vehicle body. The vehicle body is provided with a vehicle-mounted camera, and the vehicle-mounted camera cleaning system 1 is installed inside the vehicle body. The vehicle-mounted camera cleaning system 1 is used to clean the vehicle-mounted camera.

[0044] In some embodiments, the vehicle also includes a storage tank for storing windshield washer fluid, which is connected to the reservoir 7. Thus, the windshield washer fluid in the storage tank can be supplied to the reservoir 7 for use in cleaning the vehicle's onboard cameras.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
