[0050] The embodiment of the present application provides an air supply device, which is applicable to the air outlet system or air conditioning system of an automobile. As Figures 1 to 5 shown, the air supply device includes a first air duct 10 and a first cavity. One end of the first air duct 10 has a first air outlet 15, and the first air outlet 15 is adapted to communicate with the air outlet device. The other end of the first air duct 10 has a second air outlet 16, and the second air outlet 16 is used to discharge the air passing through the first air duct 10. The first cavity is arranged on one side of the first air duct 10, and the volume in the first cavity is variable to change the shape of the first air duct 10. According to the air supply device of the present application, a first cavity is arranged on one side of the first air duct 10, and the shape of the first air duct 10 is changed by changing the volume of the first cavity, thereby changing the speed and direction of the air passing through the first air duct 10. That is, the air speed and direction are controlled by changing the shape of the first air duct 10 itself, without complex mechanical control structures such as fan blades, occupying a small space and being convenient to arrange.

[0051] Specifically, the first air duct 10 is originally in a regular cylindrical or flat shape. By changing the volume of the first cavity, the first air duct 10 can be changed into different shapes such as a tapered shape or a curved shape to meet different air outlet requirements. For example, when concentrated air supply is required, the first air duct 10 can be deformed into a flat and wide shape to expand the air supply range; when precise air supply is required, the first air duct 10 can be deformed into a shape with a locally narrowed part to increase the air speed.

[0052] In one embodiment, as Figures 1 to 5 shown, the first air duct 10 includes a first side wall 11, and the first side wall 11 forms a part of the first cavity. The change in the volume in the first cavity changes the shape of the first side wall 11 to change the shape of the first air duct 10.

[0053] Specifically, the first air duct 10 is composed of multiple side walls, and at least one of the side walls is defined as the first side wall 11. The first side wall 11 has a special design and is also part of the first cavity. This means that there is no clear dividing boundary between the first side wall 11 and the first cavity, but they jointly form a continuous structure. The first cavity is separated from the outside or other components through specific boundaries, such as an elastic membrane, a deformable frame, etc. When the volume inside the first cavity changes, this change will directly act on the first side wall 11. Since the first side wall 11 is an important part of the first air duct 10, the change in its shape will directly lead to the change in the shape of the entire first air duct 10. The change in the shape of the first air duct 10 will further affect the flow characteristics of the air in the air duct. For example, when the first side wall 11 deforms towards the first chamber 20 to increase the cross-sectional area of the air duct, the flow velocity of the air in the air duct will relatively decrease; when the first side wall 11 moves away from the first chamber 20 to reduce the cross-sectional area of the air duct, the wind speed will increase.

[0054] Designing the first side wall 11 as part of the first cavity also reduces the number of components of the air supply device, making the overall structure more compact. This is not only beneficial for installation and layout in the limited space of the vehicle, but also can reduce the complexity and failure rate of the system. By changing the shape of the first side wall 11 to change the shape of the first air duct 10, the flexible adjustment of the air outlet direction can be achieved. For example, in different driving modes of the vehicle, the air outlet direction can be adjusted according to actual needs, so that the air blows more precisely towards the driver or passengers, improving comfort. At the same time, when air supply is required in different areas inside the vehicle, the air can also be guided to specific areas by adjusting the shape of the first side wall 11 to meet diverse air supply needs.

[0055] In an embodiment, the first side wall 11 is an elastic layer. The choice range of the elastic layer material is relatively wide, and a suitable material can be selected according to different performance requirements and cost budgets. For example, a rubber material with good elasticity and weather resistance can be selected, or a plastic elastomer material with lower cost and meeting the requirements can be selected. This diversity of material selection provides greater flexibility for the design and production of the air supply device. The elastic layer material enables the first side wall 11 to have excellent flexibility and deformability. When the volume of the first cavity changes, the elastic layer can quickly and smoothly change its shape, thereby accurately adjusting the shape of the first air duct 10. This precise shape change enables the flow direction and velocity distribution of the air in the air duct to be more precisely controlled. The elastic layer can better adapt to the changes in the air flow in the air duct during the deformation process, reducing the generation of air flow disorder and eddy currents. This helps to make the air flow more uniform in the first air duct 10, avoiding the situation of too high or too low local wind speed, thereby improving the air supply quality and efficiency. Inside the vehicle, a uniform air flow distribution can make the temperature and wind speed in each area more consistent, enhancing the comfort of passengers.

[0056] In one embodiment, as Figure 1 , Figure 2 and Figure 6 shown, a first support member 13 is provided on the elastic layer. When the first side wall 11 is designed as an elastic layer, the first support member 13 is provided on the elastic layer. The first support member 13 is usually made of a material with certain strength and rigidity, such as metals (such as aluminum alloy, stainless steel), hard plastics (such as polycarbonate, nylon), etc. These materials can provide the necessary support force for the elastic layer without being too heavy. The first support member 13 and the elastic layer can be connected by bonding, inlaying, snap-fitting, etc. The bonding method uses glue to firmly bond the support member to the elastic layer; the inlaying method is to reserve holes during the manufacturing process of the elastic layer and embed the support member into them; the snap-fitting method uses the snap structures on the support member and the elastic layer to achieve quick connection and disassembly. Of course, other combination methods can also be included, such as insert molding, two-color injection molding, etc. The elastic layer itself has a certain flexibility and is prone to deformation when subjected to external forces or internal pressures. The setting of the first support member 13 can effectively limit the excessive deformation of the elastic layer and maintain the relative stability of the air duct shape.

[0057] Specifically, as Figure 7 shown, it can be seen the difference in the elastic layer with and without the support member. When the elastic layer has no support member, when deformed by the medium pressure, it will present a situation where the middle is high and both sides are low. Along the axial direction of the first air duct 10, the cross-section of the first air duct 10 is uneven. When the air flow passes through, turbulence will be generated in the uneven first air duct 10, and the air outlet blowing directivity is poor. When the deformable elastic layer is embedded with the support member, due to the effect of the support member in the middle part, the deformation is very uniform in a relatively long area, thus ensuring the consistency of the axial cross-section after the elastic layer is deformed, ensuring the shape of the first air duct 10, without generating turbulence, and having a better guiding effect.

[0058] In one embodiment, as Figure 6 shown, the first support member 13 extends along the length direction of the first side wall 11. The first support member 13 is usually a long strip-shaped structure with a certain width and thickness, and its cross-sectional shape can be rectangular, trapezoidal or other shapes suitable for providing support. When the elastic layer is subjected to air flow pressure or external forces, it is prone to tensile or compressive deformation in the length direction. The first support member 13 extending along the length direction is like adding a "longitudinal backbone" to the elastic layer, which can effectively resist this longitudinal deformation and maintain the stability of the elastic layer in the length direction. At the same time, since the first support member 13 restricts the longitudinal deformation of the elastic layer, the cross-sectional area change of the first air duct 10 in the length direction becomes more uniform. This helps to improve the uniformity of the air flow in the first air duct 10, reduce the generation of air flow disorder and eddy current. The uniform air flow distribution can make the air supply volume and air speed of the air supply device more consistent at different positions, improving the air supply quality.

[0059] In one embodiment, as Figures 1 to 5 shown, the first cavity includes a first cavity wall 21, and the first cavity wall 21 is fixedly connected to the first side wall 11 to enclose the first cavity. The fixed connection effectively seals the joint between the first cavity wall 21 and the first side wall 11, preventing gas leakage from the first cavity. Good sealing performance can ensure that during the inflation or evacuation process, the internal pressure of the first cavity can change according to the design requirements, thereby accurately changing the shape of the first side wall 11 and achieving precise adjustment of the shape of the first air duct 10. Since the first cavity wall 21 is fixedly connected to the first side wall 11, when the volume of the first cavity is changed by inflation or evacuation, etc., the deformation of the first side wall 11 can occur more precisely in a preset manner. This precise deformation makes the shape change of the first air duct 10 more controllable, so that parameters such as the air outlet direction, air volume, and air speed can be adjusted more accurately. Compared with the design using blades, this solution is not affected by the blade deflection, has less air outlet occlusion, and is more beneficial to the important performance index of the air outlet area.

[0060] In one embodiment, the first cavity wall 21 is a metal part or a plastic part. The first cavity wall 21 is one of the key components constituting the first cavity, usually made of materials with certain strength and rigidity, and has strong airtightness and pressure-bearing capacity. For example, metal plates (such as aluminum alloy plates, stainless steel plates) or hard plastics (such as polycarbonate, ABS plastic). The first cavity wall 21 and the first side wall 11 are combined together through a reliable fixed connection method, and common connection methods include welding, bonding, circumferential crimping, etc. For example, for the first cavity wall 21 made of metal and the first side wall 11 made of elastic material, bonding can be used; for plastic parts, hot melt welding can also be used to achieve connection. This fixed connection ensures that there is no relative displacement between the first cavity wall 21 and the first side wall 11, so that a complete and sealed first cavity can be enclosed together.

[0061] In one embodiment, as Figures 1 to 5As shown, the first cavity is provided with a first opening 23, and the first opening 23 is adapted to introduce or discharge a medium to change the volume of the first chamber 20. The shape and size of the first opening 23 are designed according to actual requirements, and common shapes include circular, elliptical or rectangular, etc. Its size will affect the speed and flow rate of the medium introduced or discharged. Some auxiliary structures may be provided at the opening, such as a sealing gasket, a valve, etc. The sealing gasket is used to ensure the sealing performance of the opening in the closed state and prevent the leakage of the medium; the valve can precisely control the introduction and discharge of the medium. For example, an electromagnetic valve can be used, which can realize the rapid opening and closing of the valve through an electrical signal, so as to precisely adjust the flow rate of the medium. The type of the medium is not particularly limited either. Generally, air can be selected as the medium because air has a wide source, is easy to obtain and has a low cost. In some special application scenarios, other gases, such as inert gases (nitrogen, etc.), may also be used to prevent chemical reactions between the materials inside the first cavity and the medium. In addition, the introduction and discharge of the medium can be realized through manual operation or an automatic control system. Manual operation usually uses a simple valve handle, and the opening and closing of the valve are controlled by manual rotation or pushing and pulling; the automatic control system uses devices such as sensors, controllers and actuators to automatically adjust the opening of the valve according to preset parameters (such as the target volume, pressure, etc. of the first cavity), so as to achieve precise control of the introduction and discharge of the medium.

[0062] In one embodiment, as Figures 1 to 5 shown, the air supply device further includes a second chamber 30. The second chamber 30 is arranged on the other side of the first air duct 10, and the volume of the second chamber 30 is variable to change the shape of the first air duct 10. Specifically, the second chamber 30 is arranged on the other side of the first air duct 10. Here, the "other side" is relative to other structures (such as the first cavity, etc.) associated with the first air duct 10 mentioned above. For example, when the first cavity affects the shape of one side of the first air duct 10 by changing its own volume, then the second chamber 30 is located on the opposite side of the first air duct 10, and the two act on the first air duct 10 together. The arrangement of the second chamber 30 increases the dimension of the shape adjustment of the first air duct 10. Compared with only relying on a single structure (such as the first cavity) to change the shape of the first air duct 10, the second chamber 30 can exert an influence on the first air duct 10 from the other side, so that the first air duct 10 can achieve more different shape changes and meet the requirements of more air outlet scenarios. For example, in an automotive air conditioning system, according to the air supply requirements of different areas in the vehicle, by adjusting the volumes of the first cavity and the second chamber 30 respectively, the first air duct 10 can be formed into various complex shapes to achieve more precise control of the air supply direction, speed and range.

[0063] In one embodiment, as Figures 1 to 5As shown, the first air duct 10 includes a second side wall 12. The second side wall 12 is formed as part of the second chamber 30. The change in the internal volume of the second chamber changes the shape of the second side wall 12 to change the shape of the first air duct 10. The second side wall 12 does not exist independently of the second chamber 30, but directly participates in forming the wall structure of the second chamber 30. This means that the material and characteristics of the second side wall 12 are closely related to the overall structure of the second chamber 30, and they together constitute a variable-volume chamber system. The integrated design of the second side wall 12 and the second chamber 30 improves the integration of the system. The connection between each component is closer, and the collaborative work is more efficient. The interfaces and connection points between components are reduced, the probability of system failure is lowered, and at the same time, it is convenient for system maintenance and management.

[0064] Similarly, in one embodiment, as Figures 1 to 5 shown, the second side wall 12 is provided as a flexible layer. The flexibility and elasticity of the flexible layer enable it to deform when subjected to an external force, thereby dispersing the stress borne by the first air duct 10 during the shape change process. This avoids damage caused by a single structure bearing excessive stress and improves the structural reliability of the entire air supply device. During long-term use, due to the impact of air flow and pressure changes, the first air duct 10 will be subjected to repeated stress. The stress dispersion effect of the flexible layer can reduce the fatigue damage of the duct wall surface and extend the service life of the air supply device. The flexible layer here has the same structural and functional characteristics as the elastic layer mentioned above and will not be elaborated here.

[0065] In one embodiment, as Figure 1 and Figure 2 shown, a second support member 14 is provided on the flexible layer. The second support member 14 here has the same structural and functional characteristics as the first support member 13 mentioned above and will not be elaborated here.

[0066] In one embodiment, as Figure 6 shown, the second support member 14 extends along the length direction of the second side wall 12. The second support member 14 can provide a support effect along the entire length or most of the length of the second side wall 12. The presence of the second support member 14 increases the overall strength of the first air duct 10 and makes the entire air supply device more durable.

[0067] In one embodiment, as Figures 1 to 5 shown, the second chamber 30 includes a second chamber wall 31. The second chamber wall 31 is fixedly connected to the second side wall 12 to enclose the second chamber 30. The way in which the second chamber wall 31 and the second side wall 12 are fixedly connected to enclose the second chamber 30 is the same as the way in which the first chamber wall 21 and the first side wall 11 are fixedly connected to enclose the first chamber 20 mentioned above, and has the same technical effect, which will not be elaborated here either.

[0068] In one embodiment, the second chamber wall 31 is a metal part or a plastic part. Metal materials have high strength and stiffness and can withstand large pressures and external forces. In the air supply device, when the second chamber 30 needs to withstand a large internal pressure (such as in a high-pressure air supply scenario) or is affected by external collisions, vibrations, etc., the metal second chamber wall 31 can maintain the structural integrity, prevent the second chamber 30 from deforming or cracking, and thus ensure the stable operation of the entire air supply device. The density of plastic is usually much smaller than that of metal. Using a plastic part as the second chamber wall 31 can significantly reduce the overall weight of the air supply device. This is very important for some occasions with strict weight requirements (such as portable air supply equipment, air supply systems in the aerospace field, etc.), which can reduce the energy consumption and transportation costs of the equipment and improve the portability and mobility of the equipment.

[0069] In one embodiment, a second opening 32 is provided on the second chamber 30. The second opening 32 is adapted to allow a medium to enter or exit to change the volume of the second chamber 30. The technical effect of this solution is the same as that of the first opening 23 provided on the first chamber 20 mentioned above, and will not be elaborated here.

[0070] This application also provides an air outlet system, including the air supply device mentioned above.

[0071] In one embodiment, as Figure 2 shown, the air outlet system further includes a second air duct 40. One end of the second air duct 40 is connected to the first air duct 10, and the other end of the second air duct 40 is adapted to be connected to an air outlet device. The second air duct 40 serves as a transition channel between the first air duct 10 and the air outlet device. Its reasonable design can optimize the air flow path. By selecting appropriate shapes, sizes, and inner wall smoothness, the frictional resistance of the air flow during transportation can be reduced, enabling the air flow to flow more smoothly from the first air duct 10 to the air outlet device and improving the air flow transportation efficiency. For example, compared with a rectangular air duct, a circular air duct has a smoother inner wall and less air flow resistance under the same cross-sectional area.

[0072] In one embodiment, as Figure 8As shown, the air outlet system further includes a pump body 51, and the pump body 51 is communicated with the first cavity and / or the second cavity. The introduction of the pump body 51 enables the air outlet system to more precisely control the air flow parameters. By adjusting parameters such as the rotation speed and flow rate of the pump body 51, the flow rate and pressure of the medium entering the first cavity and / or the second cavity can be precisely controlled, and then parameters such as the air flow speed, flow rate, and direction in the first air duct 10 can be precisely adjusted. The pump body 51 can be only communicated with the first cavity. The pump body 51 can actively extract or convey the medium in the first cavity (such as gas, liquid, etc., usually gas in the air supply system). At this time, by changing the shape of the first side wall 11, the shape of the first air duct 10 is changed, and then controls such as air speed, air direction, and air duct closing are performed. During the working process, the pump body 51 can also adjust the flow rate and pressure of the medium in the first cavity according to the system requirements, thereby affecting the air flow state in the first air duct 10. Similarly, the pump body 51 can also be only communicated with the second cavity. When the pump body 51 is communicated with both the first cavity and the second cavity at the same time, the pump body 51 can more flexibly coordinate the work between the first cavity and the second cavity. It can reasonably distribute the flow direction and flow rate of the medium according to the overall operating state of the air supply system. For example, when the system needs to quickly respond to regulation, the pump body 51 can convey the medium to both the first cavity and the second cavity at the same time, or adjust the flow rate of the medium entering them respectively according to the actual requirements of the two cavities to achieve more efficient air flow regulation and air outlet control.

[0073] In one embodiment, as Figure 8 shown, the air outlet system further includes a valve body 52, and the valve body 52 is arranged between the pump body 51 and the first cavity or the second cavity. The valve body 52 can be arranged between the pump body 51 and the first cavity, or can be arranged between the pump body 51 and the second cavity, or valve bodies 52 can be arranged at both connection points at the same time. Taking the case of being arranged between the pump body 51 and the first cavity as an example, it is like a "checkpoint" that controls the flow of the medium between the pump body 51 and the first cavity. The valve body 52 can open, close, or adjust the size of the medium flow passage through its own structural characteristics. When the valve body 52 is open, the medium (such as gas) can smoothly flow from the pump body 51 into the first cavity or the second cavity; when the valve body 52 is closed, the medium flow passage is blocked, and the medium exchange between the pump body 51 and the cavity stops; when the valve body 52 is in the adjustment state, the size of the passage can be adjusted as needed to control the flow rate of the medium. The valve body 52 can be a solenoid valve. The solenoid valve has the characteristics of fast response and precise control, and can quickly adjust the opening degree according to the system requirements to precisely control the flow rate of the medium entering the first cavity or the second cavity from the pump body 51.

[0074] In one embodiment, as Figure 8As shown, the air outlet system further includes a detection device 53. The detection device 53 is connected to the first cavity and / or the second cavity to detect the medium parameters in the first chamber 20 and / or the second chamber 30. The detected parameters include pressure parameters, flow parameters, etc. The real-time parameters provided by the detection device 53 provide an accurate basis for the feedback adjustment of the air outlet system. The system can automatically adjust the working states of components such as the pump body 51 and the valve body 52 according to the detected parameters to achieve more precise air flow adjustment. For example, when it is detected that the pressure in the first cavity is lower than the set value, the system can automatically increase the output power of the pump body 51 to increase the pressure; when it is detected that the flow rate is too large, the flow rate can be reduced by adjusting the valve body 52.

[0075] In one embodiment, as Figure 8 shown, the air outlet system further includes a control unit 50. The control unit 50 is electrically connected to the pump body 51 and the detection device 53. The control unit 50 maintains real-time communication with the detection device 53 and can continuously obtain the medium parameters in the first cavity and / or the second cavity detected by the detection device 53, such as pressure, flow rate, temperature, humidity, etc. These parameters are important bases for the control unit 50 to make decisions and adjustments.

[0076] Specifically, as Figure 8 shown, the main working principle of this system is that the first chamber 20 and the second chamber 30 control the shape of the flexible layer by filling and sucking out the medium, change the overall shape of the first air duct 10, thereby controlling the air flow direction and air flow velocity. When receiving a signal, the pump body 51 can fill or suck out the medium into the first cavity and the second cavity. When the detection device 53, such as a flow meter, identifies that the flow rate meets the set flow rate of this scenario, the control unit 50 closes the solenoid valve after receiving the signal.

[0077] According to requirements, scenarios such as up and down blowing, sweeping, fast blowing, air outlet closing, gentle wind, etc. can be designed. Then, the built-in algorithm of the control unit 50 is designed according to the input scenarios, fully considering various parameters such as the blowing angle, outlet air speed, deformation curve of the flexible layer with the medium flow rate, angle change speed and sweeping frequency during sweeping, opening and closing and opening size of the solenoid valve, suction and discharge conditions of the pump body 51, and flow rate of the pump body 51. At the same time, overload protection is designed in the system. When the flow meter shows that the medium filled into the first cavity and the second cavity has reached overload, after this signal is given to the control unit 50, the control unit 50 will cut off the solenoid valve and stop the pump body 51 from working to avoid failure situations such as rupture or elastic loss of the flexible layer or elastic layer exceeding the design index.

[0078] Under the design of the flexible first air duct 10, the flexible layer / elastic layer is controlled by a medium, and there are no mechanisms such as motors, gears, and connecting rods. Therefore, the air outlet body occupies a relatively small layout space. Ordinary blade structures can only control the wind direction. Through the deformation of the flexible layer / elastic layer, the structure is more flexible and can control both the wind direction and the wind speed. Moreover, there is no mechanical friction during the control process, resulting in less noise.

[0079] As Figure 3 shown, in the scenario of blowing air up and down, by controlling the medium inside the first cavity and the second cavity, the first side wall 11 of the first cavity and the second side wall 12 of the second chamber 30 are deformed in the same direction. The first side wall 11 and the second side wall 12 are deformed simultaneously to form an upwardly or downwardly bent first air duct 10, which can achieve a change in the blowing angle. The control principle of the sweeping scenario is basically the same as that of the up-and-down blowing scenario. The first side wall 11 and the second side wall 12 control the continuous change of the volume of the medium inside the first cavity and the second cavity through the control unit 50, changing the shape of the flexible layer / elastic layer, thereby realizing the continuous change of the wind direction for sweeping.

[0080] As Figure 4 shown, in the scenario of rapid air blowing, by controlling the deformation of the first side wall 11 and the second side wall 12, the distance between the first side wall 11 and the second side wall 12 is continuously reduced, causing a venturi effect at the air outlet, and the wind speed will be significantly increased to achieve rapid convection and cooling. When the volumes of the first cavity and the second cavity continue to increase until the first side wall 11 and the second side wall 12 come into contact, the first air duct 10 is closed.

[0081] As Figure 5 shown, in the gentle wind scenario, the first side wall 11 and the second side wall 12 are deformed respectively in the direction close to the first cavity and the second cavity, the distance between the first side wall 11 and the second side wall 12 is continuously increased, the cross-sectional area of the air duct is significantly increased, the flow rate is slowed down, and the blown air is relatively gentle.

[0082] The method for controlling the flexible layer / elastic layer in the embodiments of the present application is to use medium pressure control. Other implementation methods, such as arranging an electromagnetic system in the first cavity and the second cavity to control the deformation of the flexible material through magnetic force, or arranging electric push rods in the first cavity and the second cavity to control the deformation of the flexible material through electric push rods, as long as the same purpose can be achieved, are within the protection scope of this solution.
