Description

Air outlet, air outlet device, air outlet equipment and vehicle

[0001] The present application relates to the field of mechanical electronics, and in particular to an air outlet, an air outlet device, an air outlet equipment and a vehicle.

[0002] With the development of science and technology, people's demand for regulating their environment has also increased, and air conditioners, air purifiers and other regulating devices are widely used.

[0003] The above-mentioned regulating devices all use the form of air supply to complete environmental regulation, so the above-mentioned regulating devices are all provided with air outlets. For example, the air outlets in the vehicle serve as the terminal of the vehicle air-conditioning output, which are used to adjust the air volume and wind direction to achieve the requirements of air circulation and temperature control in the vehicle, and provide a comfortable in-vehicle environment for the driver and passengers.

[0004] However, in order to achieve a larger air volume, the current air outlet is larger in size, which is not only not aesthetically pleasing, but also very difficult to manufacture and arrange.

[0005] Summary of the invention

[0006] The embodiment of the present application provides an air outlet, which is used to reduce the difficulty of manufacturing and arranging the air outlet while ensuring the air volume of the air outlet. The embodiment of the present application also provides a corresponding air outlet device, air outlet equipment and a vehicle.

[0007] A first aspect of the present application provides an air outlet, which includes a first structural member and a second structural member, the first structural member and the second structural member form a cavity connected to the air duct, and the air outlet blows gas from the air duct through the cavity; wherein the first structural member includes a guide portion, and the second structural member includes a first surface, the guide portion is used to guide the gas flowing along the first direction to flow along the second direction, the first direction is the direction of the gas when it flows out of the cavity, and the second direction is the direction along the first surface.

[0008] The first structural member and the second structural member in the present application form a cavity (gap), which is connected to the air duct. The gas (airflow) from the air duct flows into the cavity and flows out of the cavity, completing the blowing of the gas.

[0009] In the present application, based on the Bernoulli principle, the gas flow rate (kinetic energy) flowing out of the cavity is large, and the pressure of the gas will be small at the same height (under the same gravitational potential energy), so it can draw the surrounding gas at the same height to flow together, increasing the overall airflow blowing volume.

[0010] In the present application, the guide portion on the first structural member is used to guide the gas flowing along the first direction to flow along the second direction, the first direction is the direction when the gas flows out of the cavity, and the second direction is the direction along the first surface, that is, when the gas flows out of the cavity from the guide portion, the gas flows along the first direction. Based on the Coanda effect, the gas will deviate from the original flow direction (first direction) and instead flow in the direction (second direction) of the protruding object surface (first surface), so that the direction of the first surface can be set or adjusted according to user needs, thereby adjusting the direction of gas outflow.

[0011] In the first aspect, the air outlet includes a first structural member and a second structural member, and the first structural member and the second structural member form a cavity connected to the air duct, and the air outlet blows the gas from the air duct through the cavity, wherein the first structural member includes a guide portion, and the second structural member includes a first surface, and the guide portion is used to guide the gas flowing along the first direction to flow along the second direction, the first direction is the direction when the gas flows out of the cavity, and the second direction is the direction along the first surface. The air outlet formed by the two structural members is not only simple in structure, beautiful and easy to arrange, but also utilizes the Bernoulli principle and the Coanda effect to pull the surrounding airflow through the cavity to achieve the effect that the air outlet is greater than the air intake.

[0012] In a possible implementation manner of the first aspect, the air outlet further includes a first control component, and the first control component is used to control the air guide portion to adjust the first direction and the width of the cavity.

[0013] In this possible implementation, the first control component can adjust the first direction and the width of the cavity, that is, change the air outlet direction and air outlet volume of the air outlet, thereby improving the user experience.

[0014] In a possible implementation manner of the first aspect, the air outlet further includes a second control component, and the second control component is used to control the second structural component to adjust the second direction and the width of the cavity.

[0015] In this possible implementation, the second control component can adjust the two directions and the width of the cavity, that is, change the air outlet direction and air outlet volume of the air outlet, thereby improving the user experience.

[0016] In a possible implementation of the first aspect, the second structural member includes a first part for forming a cavity and a second part located outside the cavity, the second control member is used to control the first part to adjust the width of the cavity, and the second control member is also used to control the second part to adjust the second direction.

[0017] In this possible implementation, the second structural member can separately adjust the first part and the second part of the second structural member, that is, separately adjust the air outlet direction and air outlet volume of the air outlet, further improving the user experience.

[0018] In a possible implementation manner of the first aspect, an angle formed by the first direction and the second direction is less than 90 degrees.

[0019] In this possible implementation, the angle formed by the first direction and the second direction is less than 90 degrees, which ensures the applicability of the Coanda effect to the air outlet and improves the feasibility of the solution.

[0020] In a possible implementation manner of the first aspect, a width of the cavity is less than or equal to 30 millimeters.

[0021] In this possible implementation, the width of the cavity is less than or equal to 30 mm, which ensures the applicability of the Bernoulli principle to the air outlet and improves the feasibility of the solution.

[0022] A second aspect of the present application provides an air outlet device, which includes an air duct and an air outlet in the above-mentioned first aspect or any possible implementation of the first aspect.

[0023] In the present application, the air outlet device can be used in tools that require air ducts and air outlets, such as vehicles.

[0024] The second aspect has the same beneficial effects as the above-mentioned first aspect or any possible implementation of the first aspect.

[0025] In a possible implementation manner of the second aspect, the air outlet device also includes a ceiling structure, and the air outlet is installed on the ceiling structure.

[0026] In this possible implementation, the air outlet provided in the present application is installed in the ceiling structure. Compared with the air outlet installed on the ceiling in traditional vehicles, it solves the problems of difficult air outlet arrangement, unsightly appearance and easy dislocation of the side air curtain detonation air outlet.

[0027] In a possible implementation manner of the second aspect, the air outlet is integrally formed with the ceiling structure.

[0028] In this possible implementation, the air outlet and the ceiling structure can be produced simultaneously and formed in one piece, which reduces the production cost of the air outlet device, improves the production efficiency of the supply chain, and enhances the feasibility of the solution.

[0029] In a possible implementation manner of the second aspect, the air outlet and the air duct are integrally formed.

[0030] In this possible implementation, the air outlet and the air duct can be produced at the same time and formed as one piece. In addition, the air outlet, the air duct and the ceiling structure can also be produced at the same time and formed as one piece, which reduces the production cost of the air outlet device, improves the production efficiency of the supply chain, and enhances the feasibility of the solution.

[0031] In a possible implementation manner of the second aspect, the air outlet device has a shape of any one of an annular shape, a U shape, or a straight shape.

[0032] In this possible implementation, when the shape of the air outlet device is any one of an annular shape, a U-shape or a straight shape, a wide area coverage of the air outlet can be formed, solving the problem of concentrated air temperature and air volume at a single point of outlet and the uncomfortable perception, thereby improving the user experience.

[0033] In a possible implementation manner of the second aspect, the air duct is connected to at least one of an air humidifier, an air purifier, and a fragrance device.

[0036] In the present application, the air outlet device may be a device that needs to be provided with an air outlet.

[0037] The third aspect has the same beneficial effects as the above-mentioned first aspect or any possible implementation of the first aspect.

[0038] In a possible implementation manner of the third aspect, the air outlet device is an air conditioner or an air purifier.

[0039] In this possible implementation, when the air outlet device is an air conditioner or an air purifier, the air outlet with a simple structure reduces the production cost and difficulty of the air conditioner or air purifier, and because the cavity width of the air outlet provided in the present application is relatively small, when applied to the above-mentioned furniture and electrical appliances, the structure of the air outlet is easy to hide, thereby improving the aesthetics, and based on the structural characteristics of the air outlet, effects such as soft air outlet and uniform temperature can be achieved.

[0040] A fourth aspect of the present application provides a vehicle, which includes the air outlet device in the above-mentioned second aspect or any possible implementation of the second aspect.

[0041] In the present application, the vehicle may be a vehicle that requires an air duct and an air outlet.

[0061] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only embodiments of a part of the present application, rather than all embodiments. It is known to those skilled in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0062] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, 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 that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0063] The embodiment of the present application provides an air outlet, which is used to reduce the difficulty of manufacturing and arranging the air outlet while ensuring the air volume of the air outlet. The embodiment of the present application also provides a corresponding air outlet device, air outlet equipment and a vehicle. The following are detailed descriptions.

[0064] The following is an explanation of the terminology concepts involved in the embodiments of the present application.

[0065] (1) Coanda Effect

[0066] As shown in Figure 1, the Coanda effect is also called the wall attachment effect or the Coanda effect. The fluid (water flow or air flow) tends to deviate from the original flow direction and flow along the protruding surface of an object. When there is surface friction between the fluid and the surface of the object it flows through (also known as fluid viscosity), as long as the curvature is not large, the fluid will flow along the surface of the object, for example, the air in Figure 1 will flow along the curved wall.

[0067] (2) Bernoulli principle

[0068] As shown in Figure 2, Bernoulli's principle is essentially the conservation of mechanical energy of the fluid. Simply put, kinetic energy + gravitational potential energy + pressure potential energy = constant, and there is a famous corollary: when the flow is at equal height, the greater the flow rate, the smaller the pressure.

[0069] The following is an example of the application scenario involved in the embodiments of the present application.

[0070] With the development of science and technology, people's demand for regulating their own environment has also increased. Air conditioners, air purifiers and other environmental regulating devices are widely used. These regulating devices all use air supply to complete environmental regulation. Therefore, the above-mentioned regulating devices are all provided with air outlets. For example, central air conditioners are installed above the room and provide air to users from above through air outlets. However, most of the air outlets are large in size, making the manufacture and arrangement of the air outlets difficult, and the appearance is not beautiful enough. Therefore, how to optimize the air outlets has become a problem that needs to be solved urgently.

[0071] Specifically, taking the application scenario of a vehicle as an example, as shown in Figure 3, in addition to the air outlets set behind the traditional instrument panel and the center console armrest, in order to further enhance the experience of the rear passengers (the second row, third row, etc. of the vehicle), air outlets can also be added to the roof of the rear row of the vehicle to provide air to the rear passengers from above.

[0072] As shown in FIG4A and FIG4B , the ceiling is generally composed of a ceiling body, a ceiling bracket and ceiling accessories, and the air outlet is generally composed of a dial, blades, a connecting rod, a shell, etc., which is installed on the ceiling and connected to the air duct. The user adjusts the wind direction up and down, left and right through the dial. The air duct is generally connected to the air outlet at one end and the vehicle air conditioner at the other end. In addition, the air outlet can also be set on the peripheral structure of the ceiling such as the top cover sheet metal, skylight or skylight glass.

[0073] However, for passengers, the air outlets are arranged at a high position, and it is not convenient to adjust them by raising your hand. The air outlets can only discharge air from a set point with limited position and angle, and the temperature changes and wind speed are concentrated, resulting in excessive and uneven local body sensations (such as the air outlet blowing towards the head, high local wind speed and low temperature in the head, which is uncomfortable, etc.). In addition, the air outlets, handles, reading lights, speakers and other devices are concentrated on the roof of the vehicle, which looks messy and not beautiful enough. In addition, in the summer, when the vehicle is exposed to the sun, the user gets in the car, opens the window and turns on the air conditioner. Because of the single-point air outlet, the air convection is slow, the heat dissipates slowly, and the temperature drops slowly.

[0074] For vehicle manufacturers, the air outlets, handles, reading lights, speakers, air ducts, side air curtains and other devices are concentrated in the back row of the vehicle, which makes their arrangement difficult. In addition, the air outlets are arranged near the side air curtains, posing a safety risk of explosion and flying out to injure people.

[0075] The air outlet, air outlet device, air outlet equipment and vehicle provided in the embodiments of the present application are described in detail below in combination with the above application scenarios.

[0076] As shown in FIG. 5 , an embodiment of the air outlet provided in the present application includes a first structural member 110 and a second structural member 120 .

[0077] Among them, the first structural member 110 and the second structural member 120 form a cavity 130 connected to the air duct (not shown in the figure, it should be understood that the air duct can be connected to any position of the air outlet), and the air outlet blows the gas from the air duct through the cavity 130. The first structural member 110 includes a guide portion 111, and the second structural member 120 includes a first surface 121. The guide portion 111 is used to guide the gas flowing along the first direction to flow along the second direction. The first direction is the direction of the gas flowing out of the cavity, and the second direction is the direction along the first surface.

[0078] Specifically, the first structural member and the second structural member form a cavity (gap), which is connected to the air duct, and the gas (airflow, such as air flow) from the air duct flows into the cavity and flows out of the cavity to complete the blowing of the gas.

[0079] Referring to the Bernoulli principle shown in FIG2 , the gas velocity (kinetic energy) flowing out of the cavity is large, and the pressure of the gas will be small at the same height (under the same gravitational potential energy), so it can draw the surrounding gas at the same height to flow together, increasing the overall airflow volume.

[0080] Optionally, in order to ensure the applicability of the Bernoulli principle to the air outlet provided in the embodiment of the present application, the width of the cavity is less than or equal to 30 mm.

[0081] Furthermore, the guide portion on the first structural member is used to guide the gas flowing along the first direction to flow along the second direction, the first direction is the direction when the gas flows out of the cavity, and the second direction is the direction along the first surface, that is, when the gas flows out of the cavity from the guide portion, the gas flows along the first direction. Referring to the Coanda effect shown in Figure 1, the gas will deviate from the original flow direction (first direction) and instead flow in the direction (second direction) of the protruding object surface (first surface), so that the direction of the first surface can be set or adjusted according to user needs, thereby adjusting the direction of gas outflow.

[0082] Optionally, in order to ensure the applicability of the Coanda effect to the air outlet provided in the embodiment of the present application, the angle formed by the first direction and the second direction is an acute angle, which is less than 90 degrees.

[0083] Optionally, as shown in Figure 6, the air outlet also includes a first control member 112 and a second control member 122, the first control member 112 is used to control the guide portion 111 to adjust the first direction and the width of the cavity 130, and the second control member 122 is used to control the second structural member 120 to adjust the second direction and the width of the cavity 130.

[0084] Specifically, the first control component and the second control component can be electrically connected to a control unit in the device into which they are integrated. For example, in a vehicle, the first control component and the second control component are connected to a control system of the vehicle, such as a micro controller unit (MCU). A user can control the first control component and the second control component through a control panel in the vehicle to change the width, the first direction and / or the second direction of the cavity.

[0085] It should be understood that since the first control member and the second control member can respectively control the movement of the first structural member and the second structural member, the first structural member and the second structural member can be made of flexible soft materials, or the first structural member can be divided into two parts, which are connected by the first control member. The first control member can be moved to create an angle between the two parts, and the same applies to the second structural member and the second control member.

[0086] It should be understood that the width of the cavity may vary throughout the cavity. The width of the cavity referred to in the embodiments of the present application is the width of the cavity at the end point, that is, the width of the cavity at the position when the gas flows out of the cavity.

[0087] Among them, the first control member is arranged on the first structural member, and the first control member can specifically control the guide part in the first structural member. Because the first direction of the gas flowing out of the cavity is determined by the direction of the guide part, the first control member can adjust the first direction by controlling the movement of the guide part. In addition, when adjusting the direction of the guide part, the width of the cavity will also change accordingly, thereby adjusting the air outlet volume.

[0088] Similarly, the second control member is arranged on the second structural member, and the second control member can specifically control the movement of the second structural member to adjust the second direction. While adjusting the direction of the first surface of the second structural member, the width of the cavity will also change accordingly, thereby adjusting the air volume of the air outlet.

[0089] Optionally, as shown in Figure 7, the second structural member 120 includes a first part 123 for forming a cavity 130 and a second part 124 located outside the cavity 130, and the second control member 122 is used to control the first part 123 to adjust the width of the cavity 130. The second control member 122 is also used to control the second part 124 to adjust the second direction.

[0090] Among them, the first part is the part of the second structural member that forms the cavity, and the second part is the part of the second structural member that is located outside the cavity. It can be seen from Figure 7 that when the second control member controls the movement of the first part, the gas has not yet flowed out of the cavity, so at this time only the width of the cavity will be changed, that is, the air volume of the air outlet will be changed. When the second control member controls the movement of the second part, the gas has flowed out of the cavity. At this time, the gas will flow along the first surface of the second part based on the Coanda effect. When the second control member controls the direction of the first surface of the second part to change, the subsequent outflow direction of the gas will also change accordingly.

[0091] It can be seen from the above embodiments that the air outlet provided in the embodiments of the present application can bring about the following three beneficial effects including but not limited to:

[0092] (1) The air outlet formed by two structural members is not only simple in structure, but also beautiful and easy to arrange;

[0093] (2) Based on the Bernoulli principle and the Coanda effect, the air outlet of the cavity draws the surrounding airflow, achieving the effect that the air outlet volume is greater than the air intake volume.

[0094] (3) The first direction, the second direction and the width of the cavity are adjusted by the control component, so that the air outlet direction and air outlet volume can be adjusted, thereby improving the user experience.

[0095] As shown in FIG. 8A and FIG. 8B , an embodiment of the air outlet device provided in the embodiment of the present application includes an air outlet 100 , and the air outlet 100 may be the air outlet as shown in FIG. 5 to FIG. 7 described in the above embodiments.

[0096] Specifically, the air outlet device may be a furniture electrical appliance, such as an air conditioner 200 as shown in FIG. 8A , specifically a central air conditioner, or an air purifier 300 as shown in FIG. 8B .

[0097] In the embodiments of the present application, when the air outlet shown in Figures 5 to 7 is set on an air conditioner or an air purifier, the air outlet with a simple structure reduces the production cost and difficulty of the air conditioner or air purifier, and because the cavity width of the air outlet provided in the present application is relatively small, when applied to the above-mentioned furniture and electrical appliances, the structure of the air outlet is easy to hide, thereby improving the aesthetics, and based on the structural characteristics of the air outlet, effects such as soft air outlet and uniform temperature can be achieved.

[0098] The air outlet device provided in the embodiment of the present application has the same implementation method and beneficial effects as the above-mentioned air outlet, and the embodiment of the present application will not be repeated here.

[0099] As shown in FIG. 9 , an embodiment of the air outlet device provided in the embodiment of the present application includes an air duct 400 and the air outlet 100 as shown in FIGS. 5 to 7 described in the above embodiments.

[0100] Specifically, the air outlet device provided in the embodiments of the present application can be applied to a vehicle, such as a vehicle. As shown in FIG. 10, the air outlet device further includes a ceiling structure 500, which can be the ceiling structure to be installed in the vehicle. The ceiling structure 500 includes a ceiling bracket 501 and a ceiling body 502. The air outlet 100 is installed on the ceiling structure 500, specifically, it can be installed on the ceiling bracket 501 of the ceiling structure 500. The air outlet 100 is also communicated with the air duct 400. One end of the air duct 400 is connected to the air outlet 100, and the other end is connected to the vehicle air conditioner.

[0101] Optionally, when the air outlet is installed on the ceiling structure, when manufacturing the air outlet device, the air outlet, the air duct and the ceiling structure can be separately produced and then integrally installed together. For example, after the air outlet is separately disassembled, it is integrally installed together with the ceiling bracket, the ceiling body, the sky curtain glass, the fixed glass sunroof or the roof sheet metal, and the air duct. The installation methods can be snap connection, welding, screwing, gluing, etc. In addition, it can also be that the air outlet and the ceiling structure are integrally formed, or the air outlet and the air duct are integrally formed. As shown in FIG. 11, it can also be that the air outlet 100, the air duct 400 and the ceiling structure 500 are integrally formed. Specifically, the air outlet 100 and the air duct 400 are integrally formed with the ceiling bracket 501, and the ceiling bracket 501 and the ceiling body 502 are integrally formed. By the integral formation between multiple components and structural parts, the production cost of the air outlet device is reduced, and the production efficiency of the supply chain is improved.

[0102] Exemplarily, when the air outlet and the ceiling structure are integrally formed, a closed annular structure is formed along the ceiling opening. In addition to supporting and strengthening the ceiling, the ceiling bracket ensures the contour and stiffness of the ceiling opening. After integral formation, a hollow structure can also be formed inside the top bracket, which serves as an air duct or an air passage. The air flow of the air conditioner duct can be introduced into the annular structure of the entire ceiling bracket, and the air outlet blows the air flow in the hollow structure into the interior of the vehicle cockpit.

[0103] Optionally, as shown in FIGS. 12A-12C, the shape of the air outlet device is any one of an annular shape, a U shape or a linear shape, that is, the shape is: "one", "=", "U", "square" shape. Multiple air outlets can be arranged in the above shapes, so as to form a wide-area and large-area coverage of the air outlets, solve the problem of concentrated temperature and air volume at a single point of air outlet and uncomfortable perception, and improve the user experience.

[0104] Exemplarily, corresponding to the implementation manner in which the air outlet and the ceiling structure are integrally formed, the shape of the ceiling structure is any one of an annular shape, a U shape or a linear shape. The air flow in the air duct flows into the hollow structure inside the ceiling structure and flows out through multiple air outlets integrally formed with the hollow structure, for example, blown to multiple positions inside the vehicle cockpit.

[0105] Optionally, the air duct can also be connected to other functional devices in the vehicle, such as at least one of an air humidifier, an air purifier and a fragrance device, so that the air outlet blows different airflows, expanding the functional diversity of the air outlet.

[0106] The air outlet device provided in the embodiment of the present application has the same implementation method and beneficial effects as the above-mentioned air outlet, and the embodiment of the present application will not be repeated here.

[0107] It can be seen from the above embodiments that the air outlet provided in the embodiments of the present application can bring about the following four beneficial effects including but not limited to:

[0108] (1) By applying the air outlet to a device provided with a ceiling structure, the problems of difficult air outlet arrangement, unsightly appearance, and easy dislocation of the side air curtain explosion outlet are solved;

[0109] (2) The air outlet, air duct and ceiling structure can be installed separately or formed as one, which reduces the production cost of the air outlet device and improves the production efficiency of the supply chain;

[0110] (3) When the shape of the air outlet device is set differently, it can form a wide coverage of the air outlet, solving the problem of concentrated air temperature and air volume at a single point of outlet, which causes discomfort and improves the user experience.

[0111] (4) The air duct connected to the air outlet can be connected to different devices according to user needs, so that the air outlet blows different airflows, expanding the functional diversity of the air outlet.

[0112] As shown in FIG13 , an embodiment of a vehicle 600 provided in an embodiment of the present application includes an air outlet device 700, and the air outlet device 700 may be the air outlet device as shown in FIG9 to FIG12C described in the above embodiments. The vehicle 600 may be a vehicle, a ship, an airplane, a train or other transportation vehicle, and the air outlet device 700 is installed on the top of the vehicle 700.

[0113] Specifically, when the vehicle is a vehicle, an invisible (strip-shaped, 3-N-gonal or irregular-shaped) air outlet device can be provided at the position of the roof opening, the roof bracket, the roof body, the skylight glass, the fixed glass skylight or the roof cover sheet metal (or the cross beam / longitudinal beam) of the vehicle.

[0114] By setting the air outlet or air outlet device provided by the embodiment of the present application on the vehicle, the air outlet on the traditional ceiling is cancelled, and a hidden air outlet is added on the basis of the ceiling skylight opening. The air outlet and the ceiling bracket can be designed as an integrated cavity part (injection molding, stamping, etc.). The air outlet is connected to the air duct of the whole vehicle through 1 to N (N is a positive integer) air inlets. After the airflow of the air duct of the whole vehicle enters the air outlet through the air inlet, it is blown out from the air outlet cavity of the air outlet. Based on the Bernoulli principle and the Coanda effect, the blown airflow will draw the surrounding air to flow together, forming a wide-area, soft cabin air and temperature flow.

[0115] In addition, the air outlet does not require manual adjustment, and the airflow can form a natural circulation in the cabin. It has a low-speed full-area air outlet area and angle, and the temperature and wind speed are uniform and imperceptible, which quickly forms convection in the cabin, thereby achieving rapid cooling or heating. The appearance is hidden, simple and high-end, and it is decoupled from the side air curtains without the risk of explosion.

[0116] The vehicle provided in the embodiment of the present application has the same implementation method and beneficial effects as the above-mentioned air outlet device, and the embodiment of the present application will not be repeated here.

[0117] The vehicles in this application may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the vehicle may be a vehicle, which is a vehicle in a broad sense, and may be a vehicle (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), agricultural equipment (such as a mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiment of this application does not specifically limit the type of vehicle. For another example, the vehicle may be a vehicle such as an airplane or a ship.
