[0037] By means of the above figures, the explicit embodiments of the present application have been shown, which will be described in more detail hereinafter. These figures and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0038] As mentioned in the background, the cabin of a motor vehicle can protect important components of the motor vehicle, especially the rear cabin of a pure electric bus, which is usually used to accommodate and protect the main components of the electrical drive system, including at least: batteries that provide power for the electric motor and other electrical equipment of the vehicle, electric motors and transmission systems for driving, thermal management systems for heat dissipation, etc.

[0039] Due to the non-hermetic structure of the rear cabin of a pure electric bus, if the rear cabin is not cleaned for a long time, dust, sand and other dirt will gradually invade the interior of the cabin, which can cause many problems:

[0040] Especially the heat dissipation problem is very worth attention, dust, sand and other dirt may block the heat dissipation channels of the heat dissipation system or cover the heat dissipation fins, resulting in ineffective heat dissipation, and further causing the battery or motor to overheat, affecting the performance and service life of the motor vehicle;

[0041] Even cause electrical safety problems, once these dirt is brought into the electrical system by wind or rain, it will increase the risk of short circuit or electric leakage, especially in a humid environment, it may cause safety hazards;

[0042] If the cabin accumulates these dirt for a long time, it will also cause the metal components to rust or corrode, which will weaken the structural strength of the cabin and affect the overall safety and service life of the motor vehicle;

[0043] When the dirt causes the components to be blocked or damaged (such as heat dissipation fans, air vents, etc.), it will also increase the cost of daily maintenance and repair.

[0044] Therefore, it is necessary to clean the cabin regularly. In the prior art, a worker is usually arranged to configure a mobile high-pressure gas source, and a blowing gun is connected to the high-pressure gas source to blow the cabin. Not only does this need to pay labor costs, but also the blowing of the cabin is not timely and inconvenient due to the need to carry equipment.

[0045] Therefore, the cabin blowing system provided by the embodiments of the present application uses the compressor air tank of the motor vehicle itself to provide a gas source for blowing, which can effectively prevent the accumulation of dust and dirt, reduce the risk of blockage of the heat dissipation channel, electrical short circuit and the like, and improve the safety and reliability of the vehicle. The cabin blowing system is conducive to keeping the inside of the cabin clean, reducing the corrosion and rust of metal components, prolonging the service life of the cabin and its internal components, reducing the dependence on manpower, reducing the frequency and difficulty of manual cleaning, and reducing the cost of daily maintenance and repair. When dirt accumulates in the cabin, the blowing system can clean it in time, improving the cleaning efficiency.

[0046] The exemplary embodiments will be described in detail below with reference to the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0048] As shown in Figure 1 The cabin blowing system provided by the embodiments of the present application includes a compressor air tank 01, a gas conveying pipeline 100 and a gas blowing nozzle 200.

[0049] The compressor air tank 01 can be reused to supply gas to a pneumatic system, and the compressor air tank 01 is in communication with the gas inlet end of the gas conveying pipeline 100.

[0050] The gas blowing nozzle 200 is arranged in the cabin, the gas blowing nozzle 200 is in communication with the gas outlet end of the gas conveying pipeline 100, and the gas blowing nozzle 200 can blow gas to the components in the cabin.

[0051] It should be noted that the compressor air tank 01 is usually used in a motor vehicle to store compressed air generated by an air compressor, which can be used to drive the pneumatic system of the motor vehicle, such as pneumatic doors, pneumatic suspension systems, etc.; in some motor vehicles, compressed air can also be used for pneumatic braking systems to provide the required pressure for braking; compressed air can also be used for other auxiliary equipment, such as horns, pneumatic wipers, etc.

[0052] It can be known that the compressor air tank 01 is not only used to supply air to the pneumatic system, but also reused for the cabin purging system; the compressor air tank 01 is in communication with the air inlet end of the air supply pipeline 100, ensuring that the gas can be smoothly delivered to the inside of the cabin; the air supply pipeline 100 connects the compressor air tank 01 and the air blowing nozzle 200, which can use the compressed air in the compressor air tank 01 to blow the cabin through the air blowing nozzle 200 to clean the deposited dirt.

[0053] Through the above-mentioned cabin purging system, using the compressor air tank 01 of the motor vehicle itself as the air source to clean can effectively prevent the accumulation of dust and dirt, reduce the risk of heat dissipation channel blockage, electrical short circuit, etc., and improve the safety and reliability of the vehicle; the cabin purging system is conducive to maintaining the cleanliness of the inside of the cabin, reducing the corrosion and rust of metal components, prolonging the service life of the cabin and its internal components; reduces the dependence on manpower, reduces the frequency and difficulty of manual cleaning, and reduces the cost of daily maintenance and repair; when dirt accumulates in the cabin, the purging system can be used to clean it in time, improving the cleaning efficiency.

[0054] In some possible implementations, the air supply pipeline 100 is provided with a first dryer 310, which can be used to dry the airflow in the air supply pipeline 100.

[0055] It can be known that the first dryer 310 is installed in the air supply pipeline 100 and is used to remove moisture and humidity in the compressed air; when the compressed air passes through the air supply pipeline 100, the first dryer 310 absorbs or condenses the moisture in the air, thereby reducing the humidity of the air; the dried air is delivered to the air blowing nozzle through the air supply pipeline 100, ensuring that the air injected into the cabin is dry.

[0056] It should be noted that the first dryer 310 can adopt an adsorption dryer, which uses adsorbents (such as silica gel, activated alumina or molecular sieve) to adsorb moisture in the air; the compressed air passes through a drying tower containing the adsorbent, and the moisture is captured by the adsorbent, thereby achieving the effect of drying; the adsorbent needs to be regenerated after adsorbing moisture to saturation, which removes moisture from the adsorbent by heating or reducing pressure, so as to restore its adsorption capacity. The adsorption dryer can achieve very low dew point (usually up to -40°C or lower), which is suitable for occasions with high requirements for air dryness.

[0057] The first dryer 310 can also use a refrigeration dryer, which condenses water vapor into liquid water by reducing air temperature, and then separates the moisture from the air through a separator. The compressed air is first pre-cooled through a heat exchanger, and then enters a cooler for further cooling. The moisture is condensed and discharged. The dry air is reheated through the heat exchanger to improve energy efficiency. The refrigeration dryer has simple structure, convenient operation and low maintenance cost.

[0058] It should be noted that the type of the first dryer 310 is not limited in the embodiments of the present application as long as it can dry the air in the air supply pipeline 100.

[0059] By using the first dryer 310, the dry air blown out of the air blowing nozzle 200 can more effectively remove dust and dirt, avoid moisture causing dust condensation, and increase cleaning difficulty. The dry air can effectively reduce the humidity in the cabin, reduce the corrosion of the electrical system by moisture, reduce the risk of short circuit or electric leakage, and improve the electrical safety. Reducing the accumulation of moisture can effectively prevent the rusting and corrosion of metal components, prolong the service life of the cabin and its internal components. By reducing the influence of moisture on the cabin and components, the maintenance and replacement costs caused by corrosion and electrical failure are reduced.

[0060] In some possible embodiments, the number of air blowing nozzles 200 is multiple.

[0061] The air supply pipeline 100 includes a main pipeline 110 and multiple branch pipelines 120. The main pipeline 110 is in communication with the compressor air tank 01. The main pipeline 110 supplies air to the multiple air blowing nozzles 200 through the multiple branch pipelines 120.

[0062] It can be understood that the multiple air blowing nozzles 200 are distributed at different positions in the cabin, especially in the areas where dust and dirt are easy to accumulate. Each air blowing nozzle 200 can adjust the angle and jet intensity according to its position and the area to be covered, to ensure the comprehensiveness and effectiveness of cleaning. The main pipeline 110 is in communication with the compressor air tank 01. The pipeline 110 is responsible for delivering compressed air from the air tank to each branch pipeline 120. The multiple branch pipelines 120 branch from the main pipeline 110 and are respectively connected to the multiple air blowing nozzles 200, to ensure that each nozzle can obtain sufficient air source.

[0063] In this way, by arranging the plurality of blowing nozzles 200, each corner and key position in the cabin can be covered, ensuring that dust and dirt can be fully blown away. The plurality of blowing nozzles 200 can work simultaneously to complete the cleaning of the entire cabin in a short time, reducing the cleaning time and improving the efficiency. By adjusting the number and position of the blowing nozzles 200, the cabin structure and cleaning requirements can be flexibly configured according to different structures and cleaning requirements, and the adaptability is strong.

[0064] In some possible embodiments, the branch pipes 120 are provided with control valves 400 that can control the communication or closing of the branch pipes 120.

[0065] It can be understood that the control valves 400 are installed on the branch pipes 120 to control the opening and closing of the branch pipes 120. By the control valves 400, a certain branch pipe 120 can be selectively opened or closed, so as to control the working state of the corresponding blowing nozzle 200.

[0066] It should be noted that the control valves 400 can be operated in a manual or automatic manner, and the control mode of the control valves 400 is not limited in the embodiments of the present application.

[0067] By the control valves 400, the required blowing nozzles 200 can be selectively opened or closed according to actual needs, and the cleaning range and intensity can be flexibly adjusted

[0068] When the entire cabin does not need to be fully cleaned, some blowing nozzles 200 can be closed, thereby reducing the consumption of compressed air and saving energy. By reasonably using the control valves 400, the unnecessary working time of the blowing nozzles 200 can be reduced, the equipment wear is reduced, and the service life of the blowing nozzles 200 and the branch pipes 120 is prolonged. The use of the control valves 400 can realize targeted cleaning, especially when dust accumulates in some areas, the airflow can be concentrated for key cleaning, and the efficiency is improved.

[0069] In some possible embodiments, the cabin cleaning system comprises a control device 500, and an output end of the control device 500 is electrically connected with the control valves 400.

[0070] It can be understood that the control device 500 is used to manage and control the operation of the cabin cleaning system, and the output end thereof is electrically connected with the control valves 400, so as to send a control signal to open or close the control valves 400 on the branch pipes 120.

[0071] It should be noted that the control device 500 can be a control module such as a microcontroller, a communication interface module, a control chip and the like in the prior art, or can be a control system of a motor vehicle, as long as the control valves 400 can be opened and closed. The use of the control device 500 is not limited in the embodiments of the present application.

[0072] Through the control device 500, the automatic control of the blowing process can be realized, the manual intervention is reduced, the efficiency and reliability of the system operation are improved, the blowing efficiency is improved by conveniently enabling the required spray head 200, the operation is simple, the blowing work can be responded in time, and the dirt accumulation in the cabin body is avoided.

[0073] In some possible embodiments, the cabin blowing system comprises a monitoring device 600 arranged in the cabin.

[0074] The monitoring device 600 is used to obtain the dust state of the parts in the cabin, and the signal output end of the monitoring device 600 is electrically connected with the signal input end of the control device 500.

[0075] It can be understood that the monitoring device 600 is installed at a position required to monitor the dust in the cabin, and the dust state of the parts in the cabin can be obtained. The monitoring device can include a dust sensor, a camera or other suitable monitoring equipment to provide accurate dust accumulation information. The embodiments of the present application do not make specific limitations. The dust state in the cabin obtained by the monitoring device 600 can be used by the staff to determine whether the cabin blowing system needs to be started.

[0076] Through the monitoring device 600, the cabin blowing system can monitor the dust state in the cabin in real time, and find the dust accumulation problem in time. According to the real-time data provided by the monitoring device, the staff can dynamically adjust the blowing strategy to ensure that the key cleaning is performed in the area where the dust accumulates seriously. Through targeted cleaning, unnecessary blowing operation is reduced, and the cleaning efficiency and resource utilization rate are improved.

[0077] In some possible embodiments, the cabin blowing system comprises a control member 700, the signal output end of the control member 700 is electrically connected with the signal input end of the control device 500, and the control member 700 can control the control valve 400 to be communicated or closed through the control device 500.

[0078] It can be understood that the control member 700 is a component for managing and adjusting the cabin blowing system, the signal output end of the control member 700 is electrically connected with the signal input end of the control device 500, and the control member 700 can send a command to the control device 500 to make the control device 500 start or close the control valve 400. It can be understood that the control member 700 is a switch of the control valve 400. The staff generates a control signal by using the control member 700 (such as a manual command), the signal is transmitted to the control device 500, and the control device 500 adjusts the state of the control valve 400 according to the signal to realize the on-off control of the branch pipe 120.

[0079] Specifically, the control member 700 can be installed at the instrument panel of the motor vehicle, so that the staff can conveniently start the cabin blowing system to blow the dirt in the cabin, and the operation is simple and convenient.

[0080] The embodiment of the present application provides a motor vehicle, which comprises the cabin purging system.

[0081] Exemplarily, the motor vehicle can be a pure electric bus, and the rear cabin of the pure electric bus accommodates an electric drive system. The environmental safety of the electric drive system is particularly important for the pure electric bus. By using the cabin purging system, the heat dissipation of the motor can be avoided, and the corrosion and damage of elements can be avoided.

[0082] It is conceived that the air blowing nozzle 200 can also be arranged outside the cabin, so that the environment in which the motor vehicle is located can be purged, the motor vehicle can be maintained clean, and passengers can have a good riding experience.

[0083] In some possible implementation manners, the motor vehicle comprises a gas storage system 001 and a pneumatic system; the gas storage system 001 comprises an air compressor 02 and a gas storage pipeline 03, and a compressor gas tank 01 is used to form the gas storage system 001.

[0084] The air compressor 02 forms a gas flow, a first end of the gas storage pipeline 03 is in communication with the air compressor 02, a second end of the gas storage pipeline 03 is in communication with the compressor gas tank 01, and the air compressor 02 can input the gas flow to the compressor gas tank 01 through the gas storage pipeline 03.

[0085] It can be understood that the air compressor 02 is responsible for generating a high-pressure gas flow, and the pressure range is generally 0.8 to 1.2 MPa, which is the core component of the gas storage system. It can provide sufficient gas pressure to meet the cleaning requirements; the gas storage pipeline 03 is used to connect the air compressor 02 and the compressor gas tank 01, and ensure smooth transmission of the high-pressure gas flow.

[0086] In use, the air compressor 02 generates a high-pressure gas flow, which is transmitted to the gas storage pipeline 03 through the first end of the gas storage pipeline 03, and the second end of the gas storage pipeline 03 is in communication with the compressor gas tank 01, so that the high-pressure gas flow is input into the compressor gas tank 01. The compressed air in the first dryer 3101 can be used for the pneumatic system to drive components such as the air blowing nozzle 200 to clean the cabin.

[0087] Further, the gas storage pipeline 03 can be a heat dissipation hard pipe. The heat dissipation hard pipe generally refers to a hard pipe material used for heat conduction and dissipation. The heat dissipation hard pipe is usually designed to have a large surface area to increase the heat dissipation efficiency. By using the heat dissipation hard pipe, the gas storage pipeline 03 can effectively dissipate the heat generated by the compressed air in the compression process, thereby improving the overall efficiency of the system.

[0088] In some possible implementation manners, the gas storage pipeline 03 is provided with a second dryer 320, and the second dryer 320 can be used to dry the gas flow in the gas storage pipeline 03.

[0089] The second dryer 320 is installed in the air storage pipeline 03 to remove water and moisture in the compressed air.

[0090] Likewise, the second dryer 320 can adopt an adsorption dryer, or a refrigeration dryer can also be used, as long as it can play a drying role on the air in the air storage pipeline 03. The type of the second dryer 320 is not specifically limited in the embodiments of the present application.

[0091] When the compressed air passes through the air storage pipeline 03, the second dryer 320 absorbs or condenses the water in the air, thereby reducing the humidity of the air. The dried air is stored in the compressor air tank 01 and delivered to the air blowing nozzle through the pneumatic system, ensuring that the air sprayed into the cabin is dry. Dry air can effectively reduce the humidity in the cabin, reduce the corrosion of moisture on the electrical system, reduce the risk of short circuit or electric leakage, and improve electrical safety; reducing the accumulation of moisture can effectively prevent the rusting and corrosion of metal components, prolonging the service life of the cabin and its internal components.

[0092] Specifically, the second dryer 320 can be connected between the air compressor 02 and the compressor air tank 01. A four-way valve 04 is arranged on the air storage pipeline connected between the second dryer 320 and the compressor air tank 01 to manage and protect multiple circuits of the pneumatic braking system, so as to ensure that the motor vehicle can still operate safely when a fault occurs in a part of the pneumatic system, thereby improving the safety of the motor vehicle.
