Description

Technical Field

[0001] The invention belongs to the technical field of vehicle-mounted air conditioners, and in particular is a vehicle-mounted air conditioner fan speed regulation and heat dissipation component. Background Art

[0002] The car air conditioner is composed of a compressor, condenser, throttling element, evaporator, fan and necessary control components. It is an air conditioning system used to adjust the temperature and humidity in the car and provide a comfortable environment for the passengers.

[0003] A fan refers to an appliance that generates wind to keep cool on hot days. An electric fan is an electrically driven device that generates airflow. When the fan inside is powered on, it rotates, converting mechanical energy into wind energy, which is then transformed into natural wind to achieve a cooling effect.

[0004] Chinese invention patent 2017114187873 relates to the field of automotive air-conditioning technology, specifically to an on-board air-conditioning ventilation fan with air volume regulation, which is composed of a top cover, a water retaining ring, a rotating cover assembly and a fan assembly, and also includes an inner ring for fixing the fan assembly, which is a connecting part of the top cover and the rotating cover assembly and a middle ring that performs the primary seal. The water retaining ring is fixed on the top cover, and the fan of the fan assembly is an axial flow fan that can be separately removed and fixed in the inner ring; the fan has poor wind speed regulation efficiency, poor cooling effect, and poor adaptive adjustment ability.

[0005] At the same time, when the fan speed of the existing vehicle fan changes, the shape and opening size of the exhaust plate do not change, so it is impossible to adaptively adjust the changing air output size and heat dissipation efficiency. At the same time, when the fan is not started, the internal fan cannot be sealed and protected.

[0006] When the exhaust plate rotates to a certain angle, the exhaust plate will cause a certain degree of obstruction to the wind force generated by the fan, thereby changing the air output size of the box fan under the efficient working state, thereby affecting its heat dissipation efficiency and failing to meet different usage scenarios.

[0007] When the rotating fan rotates, the wind force at its center is the greatest, while the wind force gradually decreases from the center to both sides. Therefore, if the shape and size of the exhaust plate are certain, the exhaust fan will affect the wind force, which will not only reduce the heat dissipation efficiency, but also cause deformation and damage to the exhaust plate during long-term use, and thus cannot meet the high-intensity and long-term use scenarios of the car air conditioner. Summary of the Invention

[0008] In response to the above problems, the present invention provides a vehicle-mounted air-conditioning fan speed regulation and heat dissipation component, thereby solving the problem that the air outlet size remains unchanged when the fan blade rotation speed changes, and the wind force generated by the fan blade is affected when the exhaust plate rotates.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted air conditioner fan speed regulation and heat dissipation assembly, comprising a frame, a ventilator provided on the top of the frame, an air outlet provided inside the frame, a plurality of angle adjustment assemblies uniformly arranged on the top of the air outlet, and an exhaust assembly provided at the output end of the angle adjustment assembly;

[0010] A wind shield is provided on a side of the frame away from the exhaust assembly, an air inlet is provided inside the wind shield, a controller is provided on one side of the wind shield, a drive motor is provided inside the wind shield, a rotating frame is provided on the output end of the drive motor on the side close to the exhaust assembly, and a plurality of fan blades are evenly arrayed on the outer surface of the rotating frame;

[0011] The exhaust assembly includes an exhaust plate, the central axis of the exhaust plate is fixedly connected to the output end of the angle adjustment assembly, an angle sensor is provided inside the exhaust plate, a wind speed sensor is provided at one end of the exhaust plate close to the fan blade, both side surfaces of the exhaust plate close to the fan blade are hinged with elastic wind shield plates through a hinge seat, the top and bottom of the elastic wind shield plates are provided with corrugated connecting pieces, the other ends of the corrugated connecting pieces are fixedly connected to both sides of the exhaust plate, the end surface of the elastic wind shield plates away from the fan blades is provided with an elastic filter plate, the other end of the elastic filter plate is fixedly connected to the adjacent side surface of the exhaust plate;

[0012] A middle magnetic block is provided on one side of the elastic wind shield facing the exhaust plate and at the center position of one end away from the fan blade, and a middle electromagnet is provided on the two side surfaces of the exhaust plate and the elastic wind shield facing each other and at a position matching the middle magnetic block, and the magnetism of the middle electromagnet close to one end of the middle magnetic block is different from that of the middle magnetic block; side magnetic blocks are provided on one side of the elastic wind shield facing the exhaust plate and at the upper and lower ends of the middle magnetic block, and side electromagnets are provided on the two side surfaces of the exhaust plate and the elastic wind shield facing each other and at a position matching the side magnetic blocks, and the magnetism of the side electromagnet close to one end of the side magnetic block is different from that of the side magnetic block;

[0013] When the driving motor drives the fan blades to increase their rotation speed through the rotating frame, the controller controls the side electromagnets and the middle electromagnet to increase their current, and the increase in the middle electromagnet's current is greater than the increase in the side electromagnet's current. The middle electromagnet and the side electromagnet drive the elastic wind shield to move toward the exhaust plate end through the magnetic attraction with the middle magnetic block and the side magnetic block, and the middle exhaust plate end is recessed. When the angle adjustment component drives the exhaust component to rotate, the controller controls the side electromagnets to increase their current, and the controller controls the middle electromagnet on the side of the exhaust plate with the same rotation direction to increase its current, and the middle electromagnet on the side of the exhaust plate opposite to the rotation direction is de-energized.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application sets a frame, a ventilation pipe, an exhaust assembly, a driving motor, a rotating frame, a fan blade, a fan cover, a controller, an air inlet and an air outlet, and the fan cover is fixed to the frame through a threaded fixing seat, and the frame is fixed to the vehicle air-conditioning outlet with the help of a plug-in seat. The controller controls the driving motor to start, and the driving motor drives the rotating frame to rotate, and the rotating frame drives the fan blades to rotate. The rotation of the fan blades draws air from the end away from the exhaust assembly and discharges the wind along the air outlet. At the same time, the stepping motor in the angle adjustment assembly is started to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the exhaust assembly to rotate, thereby adjusting the wind angle of the air outlet, thereby improving the range and effect of wind cooling and heat dissipation. The device can effectively adjust the wind speed and angle, improve the cooling and heat dissipation efficiency of the vehicle air-conditioning fan, has stronger adaptability, better convenience and operability, and at the same time has stronger assembly stability, better detachable and adjustable performance, simple operation, and energy saving and environmental protection.

[0016] 2. The present application sets an exhaust assembly, an angle adjustment assembly, an exhaust plate, an elastic wind shield, a corrugated connecting piece, a side magnetic block, a side electromagnet, a middle magnetic block and a middle electromagnet to cooperate with each other. When the fan blade speed increases, the controller controls the side electromagnet and the middle electromagnet to increase the current of the power supply. At the same time, the magnetic force of the middle electromagnet increases more than that of the side electromagnet. Therefore, under the action of the magnetic attraction of the side electromagnet and the middle electromagnet to the side magnetic block and the middle magnetic block, the elastic wind shield moves toward the end of the exhaust plate and becomes concave in the middle. The wind force generated by the fan blade is discharged into the vehicle along the air outlet. At the same time, the wind force generated in the center of the fan blade is greater than that around it. Therefore, the gap between the middle positions of adjacent exhaust assemblies is greater than that on the upper and lower sides. When there is an angle between the rotation of the exhaust assembly and the frame, the controller controls the side electromagnet to continue to increase the current of the power supply. Therefore, the air outlet increases. At the same time, the middle electromagnet with the same rotation direction When the current flowing through the iron increases and the middle electromagnet in the opposite direction of rotation is de-energized, the strong wind in the middle position can be effectively discharged. The device can not only adaptively adjust the distance between the elastic wind shield and the exhaust plate according to the rotation speed of the fan blade, and then adjust the size of the air outlet to ensure that the wind generated by the fan blade can be thoroughly and efficiently discharged, but also adaptively adjust the distance between each position of the elastic wind shield and the exhaust plate according to the characteristics of strong wind in the middle of the fan blade and weak wind around it, so as to ensure that the wind in the center of the fan blade can be thoroughly and efficiently discharged, thereby improving the cooling and heat dissipation effect, and when the angle between the exhaust component and the frame changes, the gap between the elastic wind shield and the exhaust plate can also be adaptively adjusted to avoid the obstruction of wind by adjacent exhaust components, thereby improving its adaptability and adjustment ability, ensuring the cooling and heat dissipation efficiency in the car, achieving the best heat dissipation effect, energy saving and emission reduction, and stable and efficient.

[0017] 3. The present application sets up the mutual cooperation of components such as corrugated connecting sheets, elastic filter sheets, exhaust plates and elastic wind shields. When the adjacent elastic wind shields are in contact with each other in the initial position and the elastic filter sheets are stretched on all sides, the air pressure in the cavity formed by the corrugated connecting sheets, elastic filter sheets, exhaust plates and elastic wind shields is the largest. When the elastic wind shield moves toward the exhaust plate end, the shape of the elastic filter sheets changes synchronously, and the shape of the filter holes changes. At the same time, when the cavity is squeezed, the air moves toward the filter hole end and cleans the filter holes. The device can effectively filter dust and impurities in the car to prevent them from entering the interior of the vehicle air-conditioning fan and causing pollution, effectively improving its cleaning performance and being environmentally friendly and hygienic.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] First embodiment

[0031] like Figure 1-5 As shown, a vehicle-mounted air-conditioning fan speed regulation and heat dissipation component includes a frame 1. A vent pipe 3 is provided on the top of the frame 1. The gas flowing through the vent pipe 3 further improves the regulation of the temperature inside the vehicle. An air outlet 31 is provided inside the frame 1. The air outlet 31 is mainly used for air outlet cooling. A plurality of groups of angle adjustment components 5 are evenly arrayed on the top of the air outlet 31. The output end of the angle adjustment component 5 is provided with an exhaust component 4. The angle of the exhaust component 4 can be adjusted by the angle adjustment component 5, thereby achieving cooling at different positions, changing the wind blowing angle, and increasing the cooling range.

[0032] A hood 12 is provided on the side of the frame 1 away from the exhaust component 4. The hood 12 mainly plays a protective role. An air inlet 13 is provided inside the hood 12. A controller 30 is provided on one side of the hood 12. The controller 30 electrically controls various electrical components. A drive motor 8 is provided inside the hood 12. A rotating frame 9 is provided at the output end of the drive motor 8 close to the exhaust component 4. A plurality of groups of fan blades 10 are evenly arrayed on the outer surface of the rotating frame 9. Therefore, the controller 30 controls the drive motor 8 to start and drive the rotating frame 9 to rotate. The rotation of the rotating frame 9 drives the fan blades 10 to rotate. The rotation of the fan blades 10 generates wind force, which can not only cool down the air inlet 13 end, but also the generated wind force will move toward the air outlet 31 and be discharged into the car for wind blowing and cooling.

[0033] The angle adjustment assembly 5 includes an upper bracket 16, which is fixedly connected to the top of the air outlet 31. The internal uniform array of the upper bracket 16 is provided with multiple groups of stepper motors 17. The bottom output end of the stepper motor 17 is provided with a rotating shaft 18. The outer surface of the rotating shaft 18 is fixedly connected to the central axis of the exhaust assembly 4. The other end of the rotating shaft 18 is provided with a lower bracket 21 through a bearing. The lower bracket 21 is fixedly connected to the bottom of the air outlet 31. Therefore, when the stepper motor 17 is started, it will drive the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 will drive the exhaust assembly 4 to rotate to generate wind force, and then discharge the wind force through the air outlet 31. At the same time, the upper bracket 16 and the lower bracket 21 can effectively limit the stepper motor 17 and the bearing, thereby improving its movement efficiency and movement stability.

[0034] The other end of the controller 30 is provided with an electrical connection line 11, and the other end of the electrical connection line 11 is electrically connected to an external power supply through a plug. The vehicle air-conditioning fan can be powered through the electrical connection line 11, thereby improving its electrical connection performance and ensuring its operational stability and operability.

[0035] A plurality of reinforcing brackets 7 are evenly arranged on the side of the wind hood 12 away from the exhaust assembly 4. The reinforcing brackets 7 can effectively improve the strength of the wind hood 12 to prevent it from being damaged and deformed when moving with the vehicle and working for a long time, thereby reducing its durability. A threaded fixing seat 2 is provided at the other end of the reinforcing bracket 7. The threaded fixing seat 2 is connected to the side thread of the frame 1 through a connecting bolt. Therefore, the wind hood 12 and the frame 1 can be connected through the threaded fixing seat 2, which effectively improves its stability and connectivity, and has a better assembly effect and stronger assembly stability.

[0036] A plurality of bolt grooves 29 are evenly arranged on the side of the air hood 12 away from the exhaust assembly 4, and a fixing bolt 14 is provided in the bolt groove 29. The other end of the fixing bolt 14 is threadedly connected to the drive motor 8. The fixing bolt 14 can stably connect the air hood 12 to the drive motor 8 to avoid the vibration generated when the drive motor 8 is working, which may cause the air hood 12 to separate from the frame 1.

[0037] Cold air or hot air circulates in the ventilation pipe 3. The cold air or hot air is provided by the air conditioning system in the vehicle. The hot air is generated by the engine, and the cold air is made by compressing the air with the help of a compressor and an evaporator. Therefore, the hot air or cold air generated by the ventilation pipe 3 cooperates with the rotation of the fan blades 10 to adjust the temperature inside the vehicle, effectively improving the stability and safety of the work, saving energy and reducing emissions, and being safe and reliable.

[0038] A socket 6 is provided at the bottom of the frame 1, and a hinged frame 15 is provided at the bottom of the frame 1. The socket 6 and the hinged frame 15 are matched with the vehicle air-conditioning hole. The socket 6 can not only improve its stability, but also have high assembly efficiency and strong assembly stability. At the same time, with the help of the hinged frame 15, the angle of the frame 1 can be changed, thereby effectively improving the adjustability and angle of the device.

[0039] When in use, the air hood 12 is spliced ​​with the frame 1 and fixed by the threaded fixing seat 2 and the connecting bolts. At the same time, the frame 1 is plugged into the corresponding vehicle air-conditioning position and fixed with the help of the socket 6. After the assembly is completed, the controller 30 controls the drive motor 8 to start, and the drive motor 8 starts to drive the rotating frame 9 to rotate. The rotation of the rotating frame 9 drives the fan blades 10 to rotate. When the fan blades 10 rotate, the air will be drawn away from the side of the frame 1 from the air hood 12, so that it is discharged to the air outlet 31 along the air inlet 13. At the same time, the controller 30 controls the cold air or hot air circulating in the ventilation pipe 3 to assist the rotation of the fan blades 10 to cool down or heat up the car, thereby realizing the control of the vehicle air-conditioning fan.

[0040] At the same time, by controlling the rotation efficiency of the drive motor 8 through the controller 30, the wind force can be effectively adjusted, thereby realizing the speed regulation performance of the vehicle air conditioner, and the controller 30 can control the rotation of the stepper motor 17 in the angle adjustment component 5, and then the stepper motor 17 drives the rotating shaft 18 to rotate, and the rotation of the rotating shaft 18 drives the exhaust component 4 to rotate, and the wind angle of the fan can be adjusted to meet the actual cooling and heat dissipation needs, thereby improving the accuracy and comfort of the regulation.

[0041] The device can effectively adjust the wind speed and angle, improve the cooling and heat dissipation efficiency of the vehicle air-conditioning fan, have stronger adaptability, better convenience and operability, and at the same time have stronger assembly stability, better disassembly and adjustment performance, simple operation, and energy saving and environmental protection.

[0042] Second embodiment

[0043] like Figure 6-10As shown, in actual use, when the stepper motor 17 is started to drive the exhaust component 4 to rotate, the wind angle will change accordingly. However, since the common exhaust components 4 are all long plates, the opening of the air outlet 31 will be blocked when the exhaust component 4 rotates, and the wind force generated by the fan blades 10 collides between adjacent exhaust components 4 to cause obstruction, thereby reducing the air outlet efficiency and affecting the cooling and heat dissipation efficiency of the vehicle air-conditioning fan. At the same time, when the rotation speed of the fan blades 10 changes, the air outlet efficiency of the exhaust components 4 of equal width is constant, so the wind force generated by the rotation of the fan blades 10 cannot be effectively adjusted and discharged, thereby greatly reducing the adaptability and adjustability of the device. When the fan blades 10 rotate, the wind force generated at the center position is large, and the wind force gradually decreases from the center to the surrounding areas. Gradually decreases, so the exhaust component 4 cannot adaptively adjust the wind force generated by the same speed of the fan blade 10 at different positions. In order to solve the above problems, the improvement device adaptively adjusts the wind force generated by the fan blade 10, and adaptively adjusts the air outlet efficiency of the exhaust component 4 according to the change of the angle of the exhaust component 4. The vehicle-mounted air-conditioning fan speed regulation and heat dissipation component also includes: the exhaust component 4 includes an exhaust plate 19, and an angle sensor is provided inside the exhaust plate 19. The angle value of the rotation of the exhaust plate 19 can be detected by the angle sensor. A wind speed sensor is provided at one end of the exhaust plate 19 close to the fan blade 10. With the help of the wind speed sensor, the wind speed value of the fan blade 10 reaching the exhaust plate 19 close to the fan blade 10 can be detected. The central axis of the exhaust plate 19 is at the same level as the angle adjustment component. The output end of component 5 is fixedly connected, and the exhaust plate 19 is mainly fixedly connected to the rotating shaft 18. Therefore, when the stepper motor 17 is started, the rotating shaft 18 will be driven to rotate, and the rotation of the rotating shaft 18 will drive the exhaust plate 19 to rotate. The two side surfaces of the exhaust plate 19 close to the fan blade 10 are hinged with elastic wind shields 20 through hinge seats 27. The top and bottom of the elastic wind shield 20 are provided with corrugated connecting pieces 22. The other end of the corrugated connecting piece 22 is fixedly connected to both sides of the exhaust plate 19, so the elastic wind shield 20 can rotate around the exhaust plate 19. The width of the end of the exhaust plate 19 close to the fan blade 10 is constant, and the end of the exhaust plate 19 away from the fan blade 10 can change its width value with the help of the elastic wind shields 20 on both sides, and then according to the rotation speed of the fan blade 10 and the exhaust The rotation angle of the plate 19 adaptively adjusts the gap between the elastic wind shield 20 and the exhaust plate 19, reduces the resistance to wind force, ensures that the wind force generated by the fan blade 10 is discharged along the air outlet 31 to the greatest extent, avoids energy waste, and effectively avoids the wind force generated by the fan blade 10 to damage the exhaust plate 19 during long-term use. The end face of the elastic wind shield 20 away from the fan blade 10 is provided with an elastic filter 28, and the other end of the elastic filter 28 is fixedly connected to the two side faces of the exhaust plate 19; the elastic filter 28 not only plays the role of elastic connection between the elastic wind shield 20 and the exhaust plate 19, but also can filter the end of the exhaust component 4 away from the fan blade 19 with the help of the elastic elastic filter 28 to ensure the cleanliness of its interior.

[0044] A central magnetic block 25 is provided at the center of one side of the elastic windshield 20 facing the exhaust plate 19 and away from one end of the fan blade 10. A central electromagnet 26 is provided on both sides of the exhaust plate 19 and the elastic windshield 20 facing each other and matching the central magnetic block 25. The magnetic properties of one end of the central electromagnet 26 close to the central magnetic block 25 are different from those of the central magnetic block 25. Therefore, when the central electromagnet 26 is energized, the magnetic attraction of the central electromagnet 26 on the central magnetic block 25 drives the elastic windshield 20 to be concave toward the middle, as shown in FIG. Figure 7 As shown, with the help of the magnetic attraction force, the gap between the two adjacent exhaust components 4 can be effectively increased, so as to meet the different distribution conditions of the wind force generated when the fan blade 10 rotates. The elastic wind shield 20 is facing one side of the exhaust plate 19 and is located at the upper and lower ends of the middle magnetic block 25. Side magnetic blocks 23 are provided on the two side surfaces facing the exhaust plate 19 and the elastic wind shield 20 and at positions matching the side magnetic blocks 23. The magnetism of the side electromagnet 24 close to the side magnetic block 23 is different from that of the side magnetic block 23. When the side electromagnet 24 is started, the elastic wind shields 20 on both sides of the exhaust plate 19 can be driven to move toward the end of the exhaust plate 19 with the help of the magnetic attraction force of the opposite side magnetic block 23, reducing the width of the exhaust component 4 away from the end of the fan blade 10, and adaptively adjusting the change in the rotation speed of the fan blade 10 or the change in the angle of the exhaust plate 19 to avoid the exhaust component 4 from causing loss of wind force generated by the fan blade 10 and reducing energy utilization.

[0045] The corrugated connecting piece 22 is elastic. When the side electromagnet 24 is started and applies magnetic attraction force to the side magnetic block 23, the corrugated connecting piece 22 is squeezed and deformed. When the side electromagnet 24 is turned off, the corrugated connecting piece 22 drives the elastic wind shield 20 to return to its original position under the action of elastic force, and the adjacent elastic wind shields 20 are in contact. Therefore, when the device is in the initial state, the stepper motor 17 drives the rotating shaft 18 to rotate so as to realize the horizontal placement of the exhaust plate 19 and the frame 1. At this time, the side electromagnet 24 and the middle electromagnet 26 are not started. Then, under the elastic force of the corrugated connecting piece 22, the distance between the elastic wind shields 20 on both sides away from the fan blade 10 and the exhaust plate 19 is the largest, and the adjacent elastic wind shields 20 are in contact with each other, then the air outlet 31 end is in a closed state. With the help of this state, the internal vehicle air-conditioning fan can be effectively sealed and protected to prevent excessive dust and impurities from entering when it is not in use and causing damage to the internal electrical components.

[0046] The elastic filter 28 has a plurality of filter holes arranged in a uniform array inside. When the elastic filter 28 is deformed, the filter holes are also deformed. When the elastic wind shield 20 continuously rotates around the exhaust plate 19, the elastic wind shield 20 will squeeze or stretch the elastic filter 28, and the shape of the elastic filter 28 will continue to change, and the filter holes in the elastic filter 28 will continue to change synchronously. Then, in conjunction with the change in the air pressure difference between the elastic wind shield 20 and the exhaust plate 19, the filter holes in the elastic filter 28 can be cleared and blocked to avoid blockage during long-term use, thereby improving the cleaning performance.

[0047] When the fan blades 10 rotate, the wind force generated by the fan blades 10 gradually decreases toward both sides along the center position. Therefore, the device can adaptively adjust the vertical gap between adjacent exhaust components 4 according to the rotation speed of the fan blades 10, thereby achieving a larger gap at the center of rotation of the fan blades 10, and the gaps on both sides are adaptively adjusted according to the actual size of the wind speed to avoid obstruction to the wind force generated by the fan blades 10 and energy loss. The surface of the side of the elastic wind shield 20 away from the exhaust plate 19 is smooth and has no wind resistance. Therefore, no matter how the elastic wind shield 20 is deformed, the influence of its side on the wind force can be ignored. The wind force generated by the fan blades 10 can be discharged quickly and efficiently along the air outlet 31 and cool the interior of the vehicle.

[0048] During use, in the initial state, the stepper motor 17 is in the initial state, the exhaust plates 19 are in a horizontal state with the frame 1, and the exhaust plates 19 are in a vertical state with the wind cover 12, the side electromagnets 24 and the middle electromagnets 26 are in a power-off and non-operating state. At this time, under the elastic force of the corrugated connecting piece 22, the elastic wind shield 20 is farthest away from the end of the fan blade 10 and the exhaust plate 19 end, and the two adjacent elastic wind shields 20 are in contact with each other, and the entire exhaust assembly 4 is in a closed state away from the end of the fan blade 10, and the entire device is in a closed state, so external dust and impurities will not enter the vehicle air-conditioning fan and cause pollution to it.

[0049] When the controller 30 controls the driving motor 8 to start, the driving motor 8 drives the rotating frame 9 to rotate, and the rotating frame 9 drives the fan blades 10 to rotate. When the fan blades 10 rotate, wind force is generated, and then the wind speed sensor of the exhaust plate 19 close to the end of the fan blades 10 detects the wind speed value. At this time, the controller 30 controls the side electromagnets 24 on the upper and lower sides of the exhaust plate 19 to start according to the wind speed value. After the side electromagnets 24 are started, they will drive the elastic wind shield plate 20 to move close to the end of the exhaust plate 19 by means of the magnetic attraction between the side magnetic block 23. Then, the elastic wind shield plates 20 on both sides of the exhaust plate 19 rotate around the hinge seat 27 and move to the end of the exhaust plate 19. The entire exhaust assembly 4 is opened. At this time, the wind force generated by the fan blades 10 The wind can be discharged outwards along the exhaust assembly 4 into the vehicle for cooling and heat dissipation. At the same time, the greater the wind speed generated by the fan blade 10, the greater the current flowing through the corresponding side electromagnet 24, and the smaller the gap between the elastic wind shield 20 and the exhaust plate 19, the larger the opening between adjacent exhaust assemblies 4, and more wind can be discharged into the vehicle for cooling. With the help of this adjustment process, the gap between the exhaust assemblies 4 can be effectively and adaptively adjusted according to the wind force generated by the fan blade 10, and then the size of the opening between the adjacent exhaust assemblies 4 can be adjusted to ensure that the wind can be discharged thoroughly and efficiently, avoiding external dust and impurities from polluting the internal vehicle air-conditioning fan when not in use, improving the cooling effect, and ensuring the cooling efficiency.

[0050] When the vehicle air-conditioning fan is not started, the distance between the elastic wind shield 20 and the exhaust plate 19 is the largest. At this time, the tensile force on the four sides of the elastic filter 28 is the largest, and the shape of the filter holes inside the elastic filter 28 is the largest. When the controller 30 controls the side electromagnet 24 to be energized and has magnetic force, the elastic wind shield 20 moves toward the end of the exhaust plate 19, and the tensile force on the four sides of the elastic filter 28 is reduced. The elastic filter 28 will shrink inward synchronously, and the shape of the filter holes in the elastic filter 28 will change. At the same time, the air pressure in the cavity composed of the exhaust plate 19, the elastic wind shield 20, the corrugated connecting plate 22 and the elastic filter 28 in the exhaust assembly 4 is reduced when it is squeezed, and the internal air pressure will be discharged outward along the filter holes in the elastic filter 28, so that impurities blocked in the filter holes of the elastic filter 28 will be blown out, ensuring its cleaning effect and preventing it from entering the cavity and causing pollution.

[0051] At the same time, since the wind force generated at the axis of the fan blade 10 is the largest when it rotates with the rotating frame 9, and the wind force gradually decreases along the axis to the surrounding areas, in order to ensure that the wind force generated by the fan blade 10 can be blown into the car thoroughly and efficiently without any obstruction or influence on the wind force, when the fan blade 10 rotates, the controller 30 will not only start the side electromagnet 24 to work, but also start the middle electromagnet 26 to work. With the help of the magnetic attraction of the middle electromagnet 26 to the middle magnetic block 25, the middle magnetic block 25 will drive the middle position of the elastic windshield 20 to move toward the end of the exhaust plate 19. At the same time, if the power-on current of the middle electromagnet 26 of the same exhaust component 4 is greater than that of the side electromagnet 24, the exhaust component 4 will have a similar Figure 7 The structural shape shown, that is, the distance between the upper and lower sides of the elastic wind shield 20 and the exhaust plate 19 is greater than the distance between the middle position and the exhaust plate 19, and the elastic wind shields 20 on both sides of the exhaust plate 19 are recessed toward the end close to the exhaust plate 19. Therefore, the gap between the two adjacent exhaust components 4 at the middle position is greater than the upper and lower sides. This design can ensure that the gap between the exhaust components 4 located at the center position of the fan blade 10 is larger, and more wind force can be discharged quickly and efficiently. At the same time, the power-carrying currents of the middle electromagnets 26 of the multiple groups of exhaust components 4 in the frame 1 are different. Specifically, the power-carrying current of the middle electromagnet 26 in the exhaust component 4 at the middle position is the largest, and at the same time, the power-carrying current of the middle electromagnet 26 in the exhaust component 4 gradually decreases toward both sides. This design is more conducive to the wind located at the central axis of the fan blade 10 The force can be better discharged along the gap between adjacent exhaust components 4, thereby efficiently and orderly performing wind cooling and heat dissipation. Similarly, when the rotation speed of the fan blade 10 increases, the controller 30 will synchronously control the side electromagnet 24 and the middle electromagnet 26 to increase the power-on current, and the increase in the power-on current of the middle electromagnet 26 of the same exhaust component 4 is greater than the power-on current of the side electromagnet 24. At the same time, the increase in the power-on current of the side electromagnets 24 and the middle electromagnet 26 of multiple groups of exhaust components 4 gradually decreases from the middle position to both sides. In this way, the stability and efficiency of the speed regulation and heat dissipation of the vehicle air-conditioning fan can be ensured, as well as the adaptive adjustment ability of the rotation of different fan blades 10, to ensure that more wind force can be discharged evenly, efficiently and orderly, avoiding obstruction and influence, or the occurrence of uneven heat dissipation.

[0052] When the current flowing through the middle electromagnet 26 is greater than the current flowing through the side electromagnet 24 and the elastic windshield 20 is sunken and tilted, the tensile force exerted on the elastic filter 28 will also change accordingly. Therefore, the shape of the filter holes in the elastic filter 28 will change synchronously. With the help of the change in the shape of the filter holes of the elastic filter 28 and the change in the pressure in the cavity, the dust and impurities stuck in the filter holes can be better cleaned to ensure its cleanliness and filtering performance.

[0053] When the angle of the wind blowing needs to be adjusted, the rotation speed of the fan blade 10 remains unchanged. At this time, the controller 30 controls the stepper motor 17 to start, and the stepper motor 17 starts to drive the shaft 18 to rotate. The rotation of the shaft 18 drives the exhaust component 4 to rotate a certain angle, and the angle of rotation is detected by the angle sensor. At this time, there is an angle between the exhaust component 4 and the frame 1. However, no matter which direction the exhaust component 4 rotates, as long as the angle between the exhaust component 4 and the frame 1 changes, the opening size of the air outlet 31 will be synchronously reduced due to the mutual obstruction and tilt of the multiple exhaust components 4. At this time The opening needs to be adjusted to ensure that it can still achieve the optimal air outlet size when the angle of the exhaust component 4 changes. Therefore, the controller 30 controls the side electromagnet 24 to increase the power-on current. Under the action of its own magnetic force, the side electromagnet 24 will drive the elastic wind shield 20 to move toward the end of the exhaust plate 19. The distance between the elastic wind shield 20 on both sides of the exhaust plate 19 and the exhaust plate 19 is reduced, and the gap between the two adjacent exhaust components 4 is increased. Therefore, the opening size of the entire air outlet 31 again meets the optimal air outlet requirements of the wind force generated by the rotation of the fan blades 10, thereby ensuring the cooling and heat dissipation efficiency of the vehicle air-conditioning fan.

[0054] At the same time, when the exhaust component 4 rotates and is at a certain angle to the frame 1, when the wind force generated by the fan blades 10 reaches the exhaust component 4, the wind force will impact one side of the exhaust component 4, but will not cause blowing on the other side. Therefore, in order to better collect and discharge the wind force generated by the fan blades 10, the controller 30 controls the power-on current of the middle electromagnet 26 on the side with the same rotation direction as the exhaust component 4 to increase, and the middle electromagnet 26 uses the magnetic attraction with the middle magnetic block 25 to drive the middle position of the elastic wind shield 20 on this side to move toward the end of the exhaust plate 19, so that the elastic wind shield 20 on this side is more concave, and the controller 30 controls the power-on current of the middle electromagnet 26 on the other side to be cut off, so at this time the elastic wind shield 20 on the other side is no longer concave, and the angle between it and the exhaust plate 19 is only regulated by the side electromagnet 24.

[0055] Specifically, by Figure 9 It can be seen that when the rotating shaft 18 drives the exhaust plate 19 to rotate to the right, the wind force generated by the fan blade 10 will impact the elastic wind shield 20 on the right side of the exhaust plate 19. Therefore, in order to improve the collection and discharge efficiency of the wind force on this side, the controller 30 will control the current of the middle electromagnet 26 on the right side to increase. Therefore, the degree of depression of the middle part of the elastic wind shield 20 on the right side toward the end of the exhaust plate 19 increases, and the strong wind force generated by the center of the fan blade 10 can be discharged more efficiently and quickly; and the elastic wind shield 20 on the left side is no longer impacted by the wind force, so the middle electromagnet 26 of the elastic wind shield 20 on the left side can meet the required requirements by turning off the power, and the elastic wind shield 20 on the left side only relies on the side electromagnet 24 to regulate the distance between it and the exhaust plate 19.

[0056] At the same time, it can be seen from the above that since the wind force generated by the fan blade 10 is larger in the middle and smaller around, when the exhaust component 4 rotates and has an angle with the frame 1, the wind force generated by the fan blade 10 does not change. By increasing the current of the side electromagnet 24 and the middle electromagnet 26, the wind resistance caused by adjacent exhaust components 4 can be effectively adjusted, thereby ensuring that the wind force generated by the fan blade 10 can be discharged sufficiently and efficiently to complete heat dissipation and cooling.

[0057] When the exhaust component 4 rotates and there is an angle with the frame 1, and the rotation speed of the fan blade 10 increases, it can be seen from the above that the controller 30 will increase the current of the side electromagnet 24 and then drive the elastic wind shield 20 to move toward the end of the exhaust plate 19 through the magnetic attraction with the side magnetic block 23, so that the gap between adjacent exhaust components 4 increases, and the wind force can be effectively adjusted. At the same time, since the wind force generated by the fan blade 10 is larger in the middle and smaller around, the controller 30 will control the current of the middle electromagnet 26 on the side with the same rotation direction to increase, and the increase in the current of the middle electromagnet 26 is greater than the increase in the side electromagnet 24. Therefore, the elastic wind shield 20 on this side is more concave inward, and the middle electromagnet 26 in the exhaust plate 19 on the other side is powered off, and the distance between the elastic wind shield 20 on this side and the exhaust plate 19 is only regulated by the side electromagnet 24.

[0058] When the exhaust is completed, the controller 30 controls the stepper motor 17 to start in reverse and drive the exhaust assembly 4 to return to its original position through the rotating shaft 18, and the drive motor 8 stops rotating. The wind speed value detected by the wind speed sensor is zero, and the controller 30 controls the side electromagnet 24 and the middle electromagnet 26 to cut off the power. Under the elastic force of the corrugated connecting piece 22, the elastic wind shields 20 on both sides of the exhaust plate 19 are restored to their original positions, and the adjacent elastic wind shields 20 are in contact with each other, and the entire device is in a closed state.

[0059] The device can not only adaptively adjust the distance between the elastic wind shield 20 and the exhaust plate 19 according to the rotation speed of the fan blade 10, and then adjust the size of the air outlet 31 to ensure that the wind generated by the fan blade 10 can be discharged thoroughly and efficiently, but also adaptively adjust the distance between each position of the elastic wind shield 20 and the exhaust plate 19 according to the characteristics of the fan blade 10 that the wind force is strong in the middle and the wind force is weak around it, so as to ensure that the wind force at the center position of the fan blade 10 can be discharged thoroughly and efficiently, thereby improving the cooling and heat dissipation effect, and when the angle between the exhaust component 4 and the frame 1 changes, the gap between the elastic wind shield 20 and the exhaust plate 19 can also be adaptively adjusted to avoid the obstruction of the wind force by the adjacent exhaust component 4, thereby improving its adaptability and adjustment ability, ensuring the cooling and heat dissipation efficiency in the vehicle, achieving the best heat dissipation effect, energy saving and emission reduction, and stable and efficient.
