[0032] 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.

[0033] The terms "first," "second," etc., used in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, and the presence of both A and B, both B and C, both A and C, and the presence of A, B, and C.

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of a microphone cleaning device provided in an embodiment of this application, as shown below. Figure 1 As shown, a microphone cleaning device 200 is applied to a vehicle 100. A microphone 101 is disposed on the outer surface of the vehicle 100. The microphone cleaning device 200 includes a nozzle 201, a delivery channel 202, and a power unit 203. The nozzle 201 is disposed facing the microphone 101. The delivery channel 202 is connected to the nozzle 201 and the power unit 203 respectively, and the delivery channel 202 is used to deliver fluid for cleaning the microphone 101.

[0035] The working principle of the embodiments of this application can be described as follows:

[0036] Since the microphone cleaning device 200 includes a nozzle 201, a delivery channel 202, and a power unit 203, with the nozzle 201 facing the microphone 101 and the delivery channel 202 connected to both the nozzle 201 and the power unit 203, the power unit 203 can provide power to the fluid used for cleaning the microphone 101. The delivery channel 202 can transport the fluid, and the nozzle 201 can spray the fluid towards the microphone 101 to complete the cleaning. This improves the intelligence level of the microphone cleaning process and increases the cleaning efficiency of the microphone 101. Furthermore, the microphone cleaning device 200 also provides an automated microphone cleaning apparatus.

[0037] It should be noted that when the preset conditions are met, the nozzle 201 can be controlled to spray fluid toward the microphone 101. The specific preset conditions are not limited here, but optionally, the preset conditions may include at least one of the following:

[0038] The microphone 101 detects sound, and the impedance of the receiving circuit used to transmit the signal corresponding to the sound is greater than the preset impedance. The receiving circuit is electrically connected to the microphone 101.

[0039] The target color is present in the area where the microphone 101 is located in the image captured by the vehicle 100. The target color is the color corresponding to the stain.

[0040] Received an unlock command for controlling vehicle 100 to unlock;

[0041] A control command is received, which controls the nozzle 201 to spray fluid toward the microphone 101.

[0042] The target color can be gray or brown, which are usually the colors of mud. The control commands can include touch commands, press commands, voice commands, etc. When the control commands include voice commands, the voice content included in the voice commands can be "decontamination microphone".

[0043] The functions that the microphone 101 can perform are not limited here. Optionally, the microphone 101 can be used to realize functions such as external vehicle interaction, voice control, and environmental sound recognition. For example, when a user approaches the vehicle 100, the vehicle 100 can control the microphone 101 to collect the user's voice and control the vehicle 100's voice system to play a response audio to the user's voice, thereby realizing the function of external vehicle interaction. For another example, the vehicle 100 can also control the vehicle 100 to perform a target operation based on the user's voice collected by the microphone 101, that is, realize the function of voice control of the vehicle 100. The target operation may include at least one of the following: unlocking the vehicle 100, controlling the vehicle 100 to lock, automatic parking, and driving out of the parking space. For yet another example, the vehicle 100 can collect the sound of the external environment in which the vehicle 100 is located through the microphone 101, thereby realizing the function of environmental sound recognition.

[0044] The microphone 101 can also perform multiple functions simultaneously. For example, it can simultaneously perform voice control and environmental sound recognition. Optionally, it can collect sounds from the external environment in which the vehicle 100 is located and control the vehicle 100 for intelligent driving based on these sounds. This improves the accuracy of controlling the vehicle 100 for intelligent driving and avoids situations where the microphone 101 is blocked, resulting in untimely sound input from the external environment and causing the vehicle 100 to make incorrect judgments, thus leading to safety accidents.

[0045] For example, when the sound in the external environment where vehicle 100 is located is the siren of an ambulance or police car, vehicle 100 can be controlled to give way; as another example, when the sound in the external environment where vehicle 100 is located is the sound of a person or animal, vehicle 100 can be controlled to slow down and give way.

[0046] The specific type of vehicle 100 is not limited here. Optionally, vehicle 100 can be an intelligent vehicle, which can be understood as a vehicle 100 equipped with an intelligent driving system; alternatively, vehicle 100 can be a non-intelligent vehicle, which can be understood as a vehicle 100 that is not equipped with an intelligent driving system.

[0047] As an optional implementation, see [link to implementation details]. Figure 1 The fluid includes a gaseous fluid, the conveying channel 202 includes a gaseous fluid conveying channel 2021, the power unit 203 includes a gaseous fluid power unit 2031, the gaseous fluid power unit 2031 is connected to the nozzle 201 through the gaseous fluid conveying channel 2021, the gaseous fluid power unit 2031 is used to provide power to the gaseous fluid, and the gaseous fluid conveying channel 2021 is used to convey the gaseous fluid; and / or,

[0048] The fluid includes a liquid fluid, the conveying channel 202 includes a liquid fluid conveying channel 2022, the power unit 203 includes a liquid fluid power unit 2032, the liquid fluid power unit 2032 is connected to the nozzle 201 through the liquid fluid conveying channel 2022, the liquid fluid power unit 2032 is used to provide power to the liquid fluid, and the liquid fluid conveying channel 2022 is used to convey the liquid fluid.

[0049] Optionally, the nozzle 201 can spray either liquid fluid or gaseous fluid separately, or it can spray both liquid fluid and gaseous fluid simultaneously.

[0050] Optionally, the gaseous fluid power device 2031 may be an air pump, and the liquid fluid power device 2032 may be a liquid pump, which may include a peristaltic pump, etc.

[0051] In this embodiment, the microphone 101 can be cleaned by at least one of gaseous fluid and liquid fluid, thereby improving the cleaning effect of the microphone 101 and making the cleaning method of the microphone 101 more diversified.

[0052] As an optional implementation, see [link to implementation details]. Figure 2 When the conveying channel 202 includes a gaseous fluid conveying channel 2021 and a liquid fluid conveying channel 2022, the output ends of the gaseous fluid conveying channel 2021 and the liquid fluid conveying channel 2022 are interconnected.

[0053] In this embodiment, the output ends of the gaseous fluid delivery channel 2021 and the liquid fluid delivery channel 2022 are connected to each other. In this way, the liquid fluid and the gaseous fluid can be fully mixed before being sprayed out through the nozzle 201, thereby further enhancing the cleaning effect on the microphone 101.

[0054] As an optional implementation, the input end of the gaseous fluid delivery channel 2021 and the input end of the liquid fluid delivery channel 2022 are interconnected. This allows the liquid and gaseous fluids to begin mixing from the input ends of both channels, extending the mixing path and ensuring thorough mixing. This enhances the mixing effect and further improves the cleaning effect on the microphone 101.

[0055] As an optional implementation, the first intermediate section of the gaseous fluid delivery channel 2021 and the second intermediate section of the liquid fluid delivery channel 2022 are interconnected. The first intermediate section is the portion between the input and output ends of the gaseous fluid delivery channel 2021, and the second intermediate section is the portion between the input and output ends of the liquid fluid delivery channel 2022. This allows the liquid and gaseous fluids to mix within the first intermediate section of the gaseous fluid delivery channel 2021 and the second intermediate section of the liquid fluid delivery channel 2022, thus extending the mixing path and enhancing the mixing effect, thereby further improving the decontamination effect on the microphone 101. Furthermore, it increases the diversity and flexibility of the connection positions between the gaseous fluid delivery channel 2021 and the liquid fluid delivery channel 2022.

[0056] It should be noted that the first intermediate section can be understood as the part of the gaseous fluid transport channel 2021 located in the middle, while the second intermediate section can be understood as the part of the liquid fluid transport channel 2022 located in the middle.

[0057] As an optional implementation, the nozzle 201 includes at least one of the following: an arc-shaped nozzle, an annular nozzle, or a spherical nozzle. This allows for greater diversity in the types of nozzles 201, thus increasing the variety of nozzle types.

[0058] As an optional implementation, the nozzle 201 includes a nozzle body and a cover plate connected to each other. The nozzle body includes at least one of the following: an arc-shaped nozzle body, an annular nozzle body, or a spherical nozzle body. This increases the diversity of nozzle bodies, while the cover plate also protects the nozzle body.

[0059] It should be noted that the cover plate and the nozzle body can be rotatably connected. For example, one side of the cover plate can be fixedly connected to the nozzle body, and the other side of the cover plate can rotate relative to the nozzle body. In this way, when the other side of the cover plate comes into contact with the nozzle body, the cover plate can protect the nozzle body. When the other side of the cover plate is separated from the nozzle body, the nozzle body can spray fluid.

[0060] As an optional implementation, the nozzle body outlet includes at least one of the following: a flat outlet, a long strip outlet, a slit outlet, a linear outlet, a narrow slit outlet, or a circumferential outlet. This allows for greater diversity in the shape of the nozzle body outlet.

[0061] It should be noted that, optionally, the slit-shaped outlet may include at least one of a curved slit-shaped outlet and a wavy slit-shaped outlet.

[0062] It should be noted that the placement of the microphone 101 and the nozzle 201 on the vehicle 100 is not limited here.

[0063] Optionally, both the microphone 101 and the nozzle 201 are positioned close to the windshield of the vehicle 100, or both are positioned close to the rear windshield of the vehicle 100, or both are located on the side panel of the vehicle 100. In this way, by placing the microphone 101 and the nozzle 201 close to the windshield, rear windshield, or side panel of the vehicle 100, cleaning of the windshield, rear windshield, or side panel of the vehicle 100 can be achieved, thus enhancing the cleaning effect on the windshield, rear windshield, or side panel of the vehicle.

[0064] Optionally, the aforementioned vehicle side panel may refer to the vehicle door, the glass on the door, etc. of the vehicle 100.

[0065] It should be noted that if the area on the microphone 101 that needs cleaning is large, while the area that the nozzle 201 can clean is small, it is easy for some areas on the microphone 101 to not be cleaned in time. To solve this problem, the following implementation method is proposed:

[0066] As an optional implementation, there are multiple nozzles 201, and each nozzle 201 is positioned towards a different location on the microphone 101. By providing multiple nozzles 201, and ensuring that each nozzle 201 is positioned towards a different location on the microphone 101, timely cleaning of different locations on the microphone 101 is possible, thereby further improving the cleaning efficiency of the microphone 101.

[0067] It should be noted that, optionally, the above-mentioned multiple nozzles 201 can work simultaneously, which allows for simultaneous cleaning of multiple positions of the microphone 101, thereby improving the cleaning efficiency of the microphone 101; alternatively, each of the above-mentioned multiple nozzles 201 can also work independently, so that when a certain position of the microphone 101 needs to be cleaned, the nozzle 201 corresponding to that position can be controlled to work, thereby completing the cleaning of that position, without the need for multiple nozzles 201 to work simultaneously, reducing the cost of use and increasing the flexibility of the control method for each nozzle 201.

[0068] It should be noted that the arrangement of the above-mentioned multiple nozzles 201 is not limited here. Optionally, the above-mentioned multiple nozzles 201 can be evenly distributed, such as the above-mentioned multiple nozzles 201 can be evenly distributed in a circle, that is, the above-mentioned multiple nozzles 201 can form a circle, and the distance between any two adjacent nozzles 201 can be equal.

[0069] As an alternative implementation, the nozzle 201 can be moved relative to the microphone 101 so that the nozzle 201 can move between multiple positions and the nozzle 201 faces different positions on the microphone 101.

[0070] The nozzle 201 faces different directions on the microphone 101 depending on its position. This can be understood as follows: when the nozzle 201 moves to the first position, it faces the first target position of the microphone 101; when the nozzle 201 moves to the second position, it faces the second target position of the microphone 101. The first and second positions are different, and the first and second target positions are also different. For example, the first target position could be the center of the microphone 101, and the second target position could be the edge of the microphone 101.

[0071] In this embodiment, the nozzle 201 can be moved between multiple positions to remove dirt from different positions on the microphone 101. That is, only one nozzle 201 is needed to remove dirt from different positions on the microphone 101, which reduces the cost of use.

[0072] It should be noted that the specific way in which the drive nozzle 201 moves relative to the microphone 101 is not limited here. Optionally, the user can manually adjust the movement of the drive nozzle 201 relative to the microphone 101. For example, a groove can be provided on the outer surface of the vehicle 100, and the nozzle 201 can be slidably connected to the groove. In this way, by controlling the nozzle 201 to slide along the groove, the drive nozzle 201 can be moved between multiple positions.

[0073] As an optional implementation, see [link to implementation details]. Figure 1 The microphone cleaning device 200 also includes a drive device 204, which is connected to the nozzle 201 and is used to drive the nozzle 201 to move between multiple positions. Thus, by driving the nozzle 201 to move between multiple positions via the drive device 204, the intelligence of the driving method for the nozzle 201 can be enhanced, and the accuracy of driving the nozzle 201 to move between multiple positions can also be improved.

[0074] It should be noted that the specific structure of the drive device 204 is not limited here. Optionally, the drive device 204 can be a motor.

[0075] As an optional implementation, the difference between the angle between the outlet direction of the nozzle 201 and the normal direction of the input surface of the microphone 101 and 90 degrees is within a preset range.

[0076] The input surface of microphone 101 can be understood as the input surface of the sound collected by microphone 101. Optionally, this input surface can be a plane, and the normal direction of the input surface of microphone 101 can be referred to... Figure 2 As shown in B1, the outlet direction of nozzle 201 can be understood as the direction in which the fluid is ejected from nozzle 201. (See also...) Figure 2 The angle between the outlet direction of nozzle 201 and the normal direction of the input surface of microphone 101, as shown in A1, can be understood as... Figure 2 The angle between A1 and B1.

[0077] The specific value of the preset range is not limited here. Optionally, the preset range can be -0.1 to 0.1. When the difference between the value of the angle between the outlet direction of the nozzle 201 and the normal direction of the input surface of the microphone 101 and 90 degrees is within the preset range, it can be understood that the outlet direction of the nozzle 201 is perpendicular or approximately perpendicular to the normal direction of the input surface of the microphone 101. It can also be referred to as the outlet direction of the nozzle 201 being tangent or approximately tangent to the input surface of the microphone 101.

[0078] It should be noted that when the difference between the angle between the outlet direction of nozzle 201 and the normal direction of the input surface of microphone 101 and 90 degrees is 0, it can be said that the outlet direction of nozzle 201 is perpendicular to the normal direction of the input surface of microphone 101.

[0079] In this embodiment, since the difference between the angle between the outlet direction of the nozzle 201 and the normal direction of the input surface of the microphone 101 and 90 degrees is within a preset range, the fluid can more thoroughly clean the microphone 101, thereby enhancing the cleaning effect on the microphone 101.

[0080] As an optional implementation, the nozzle 201 includes a spray ring made of a material with a temperature resistance range of -40°C to 120°C. This allows the spray ring to have good low-temperature and high-temperature resistance.

[0081] Optionally, when the nozzle 201 also includes a nozzle body, the nozzle body and the spray ring can be fixedly connected. Alternatively, the nozzle body and the spray ring can be detachably connected, and the nozzle body can be connected to the delivery channel 202 and the spray ring respectively. The fluid can be delivered to the nozzle body through the delivery channel 202 and then sprayed out onto the microphone 101 through the spray ring. In this way, since the spray ring is made of a material with a temperature resistance range of -40℃ to 120℃, the spray ring has good low-temperature and high-temperature resistance. Regardless of whether a low-temperature fluid or a high-temperature fluid is used, the spray ring can work normally.

[0082] It should be noted that the specific types of materials with a temperature resistance range of -40℃ to 120℃ are not limited here. Optionally, materials with a temperature resistance range of -40℃ to 120℃ can be polyetheretherketone (PEEK) resin materials.

[0083] As an optional implementation, the outlet of nozzle 201 is also coated with a hydrophobic coating. This gives nozzle 201 significant properties such as detergency, moisture resistance, corrosion resistance, low friction, and long-term stability, effectively improving the performance and reliability of nozzle 201.

[0084] The outlet of nozzle 201 can be understood as the position where fluid is ejected from nozzle 201. When nozzle 201 includes a nozzle body and a spray ring that are connected to each other, the outlet of nozzle 201 can be understood as the position where the nozzle body and the spray ring are connected.

[0085] It should be noted that the specific method of generating the above-mentioned hydrophobic coating is not limited here. Optionally, the above-mentioned hydrophobic coating can be obtained by generating a 50nm thick silicon dioxide (SiO2) layer at the outlet of nozzle 201 through atomic layer deposition (ALD) process.

[0086] As an optional implementation, see [link to implementation details]. Figure 3 The nozzle 201 includes multiple sets of nozzles, each set of nozzles including a gaseous fluid nozzle 2011 and a liquid fluid nozzle 2012, and there is a preset angle R between the outlet direction of each set of nozzles and the horizontal direction corresponding to the input surface of the microphone 101.

[0087] The outlet direction of each set of nozzles can also be understood as the direction in which the gaseous fluid is ejected from the gaseous fluid nozzle 2011, and the direction in which the liquid fluid is ejected from the liquid fluid nozzle 2012, for example: see Figure 3 The direction shown in A2 is as follows, and the horizontal direction corresponding to the input surface of microphone 101 can be understood as the horizontal direction included by the plane containing the input surface, for example: see Figure 3 The direction is shown in B2.

[0088] The specific value of the preset included angle R is not limited here. Optionally, the preset included angle R can be less than or equal to 30 degrees.

[0089] Optionally, the multiple sets of nozzles can be evenly distributed, meaning that the distance between any two adjacent sets of nozzles can be equal.

[0090] In this embodiment, each set of nozzles includes a gaseous fluid nozzle 2011 and a liquid fluid nozzle 2012. This allows gaseous fluid to be ejected from the gaseous fluid nozzle 2011 and liquid fluid to be ejected from the liquid fluid nozzle 2012, ensuring that the gaseous and liquid fluids do not interfere with each other when ejected simultaneously, thus enhancing the ejection effect of the gaseous and liquid fluids. Furthermore, there is a preset angle R between the outlet direction of each set of nozzles and the horizontal direction corresponding to the input surface of the microphone 101, which allows the gaseous and liquid fluids to have a certain impact force when ejected toward the input surface of the microphone 101, thereby enhancing the cleaning effect on the input surface of the microphone 101.

[0091] See Figure 1 This application provides a vehicle 100, including a microphone 101 and a microphone cleaning device 200 as described in the above embodiments. Since the vehicle 100 provided in this application includes the microphone cleaning device 200 as described in the above embodiments, it has the same beneficial technical effects as the microphone cleaning device 200 as described in the above embodiments. The specific structure of the microphone cleaning device 200 can be found in the corresponding descriptions in the above embodiments, and will not be repeated here.

[0092] As an alternative implementation, there may be multiple microphones 101, and the multiple microphones 101 may be arranged in an array, or there may be only one microphone 101.

[0093] Optionally, when there are multiple microphones 101, the outlet of the nozzle 201 may include: a flat outlet, a long strip outlet, a slit outlet, a line outlet, or a narrow slit outlet; when there is only one microphone 101, the outlet of the nozzle 201 may include a circumferential outlet, and the circumferential outlet may be fitted onto the microphone 101.

[0094] In this embodiment of the application, when there are multiple microphones 101 and the array of multiple microphones 101 is distributed, sound can be collected from multiple locations, thereby enhancing the sound collection effect of the microphones 101; while when there is only one microphone 101, the cost of use can be saved.

[0095] The above content represents preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles disclosed in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
