Description

Technical Field

[0001] This application relates to the field of vehicle air conditioners, and particularly to a dual-channel air outlet structure. Background Art

[0002] A vehicle air conditioner is composed of a compressor, a condenser, a throttling element, an evaporator, a blower, and necessary control components, and is an air conditioning system used to adjust the temperature and humidity inside the vehicle and provide a comfortable environment for passengers.

[0003] When the vehicle air conditioner is working, the compressor sucks in the low-temperature and low-pressure gaseous refrigerant coming out of the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies into a liquid. When the liquid refrigerant flows through the throttling device, its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature and low-pressure liquid refrigerant absorbs the heat of the air inside the vehicle passing through the evaporator and evaporates into a gas. The gas is then sucked in by the compressor for the next cycle. In this way, through the circulation of the refrigerant in the system, the heat of the air inside the vehicle is continuously absorbed and discharged into the outside air, gradually lowering the temperature of the air inside the vehicle.

[0004] In the process of realizing the exchange of hot and cold gases inside and outside the vehicle, it is necessary to blow some gases into the vehicle through the air outlet structure to complete the adjustment of the temperature inside the vehicle. During the process of blowing air into the vehicle, the air outlet structure often can only exhaust air unidirectionally. If the vehicle occupants do not manually adjust the exhaust direction, the air outlet structure is likely to directly blow on the vehicle occupants during the exhaust process, resulting in a decrease in the comfort of the vehicle occupants, so it needs to be improved. Summary of the Invention

[0005] In order to improve the problem that the air outlet structure in the related art needs vehicle occupants to manually adjust the air outlet direction when adjusting the temperature inside the vehicle, this application provides a dual-channel air outlet structure.

[0006] The dual-channel air outlet structure provided by this application adopts the following technical solutions:

[0007] A dual-channel air outlet structure includes an air outlet housing. An air intake groove for air intake is provided at the bottom of the air outlet housing. A wind guiding member is arranged inside the air outlet housing. A pair of opposite side walls of the wind guiding member are fitted with the inner side walls of the air outlet housing, and the other pair of opposite side walls form a first air duct and a second air duct with the inner side walls of the air outlet housing. A wind door is arranged at the inner bottom of the air outlet housing. The wind door includes a first wind door plate, a first transmission shaft, a second wind door plate and a second transmission shaft. The first wind door plate is connected to the first transmission shaft, the second wind door plate is connected to the second transmission shaft. The first transmission shaft and the second transmission shaft are rotatably connected to the inner side walls of the air outlet housing. A driving device is arranged on one side of the air outlet housing. The driving device controls the wind door through the first transmission shaft and the second transmission shaft.

[0008] By adopting the above technical solution, when the dual-channel air outlet structure in the present application is applied to a vehicle air conditioner, the cold and hot air in the vehicle air conditioner enters the interior of the air outlet housing from the air intake groove and is separated by the wind guiding member, so that the cold and hot air respectively enter the first air duct and the second air duct. When the vehicle occupants want to directly blow the cold and hot air of the vehicle air conditioner at their bodies to obtain a more comfortable air conditioner use experience, they can control the driving device to make the driving device control the rotation of the first transmission shaft and the second transmission shaft, so that the second transmission shaft drives the second wind door plate to form a larger angle with the side wall of the wind guiding member, while the first transmission shaft drives the first wind door plate to form a smaller angle with the side wall of the wind guiding member, and even completely fit with the side wall of the wind guiding member under the drive of the driving device. As a result, most of the cold air is discharged from between the second wind door plate and the side wall of the wind guiding member, that is, the second air duct, so that it is possible to avoid directly blowing the vehicle occupants during the process of exhausting air in the vehicle. Similarly, when the vehicle occupants feel that the temperature in the vehicle is relatively high but do not need to directly blow cold air on themselves, they control the driving device to make the angle between the first wind door plate and the wind guiding member larger and the angle between the second wind door plate and the wind guiding member smaller, so that most of the cold air is blown into the vehicle from between the first wind door plate and the side wall of the wind guiding member, which not only meets the effect of cooling the vehicle interior, but also reduces the possibility of the comfort level of the vehicle occupants decreasing due to the direct blowing of the cold and hot air at the vehicle occupants, thus improving the comfort level of the vehicle occupants when using the vehicle air conditioner.

[0009] Optionally, the first transmission shaft includes a first transmission main shaft and a first connecting shaft. The second transmission shaft is a hollow tubular structure. The first connecting shaft is inserted into the second transmission shaft. The first transmission main shaft is fitted with one end of the second transmission shaft close to the first transmission main shaft. The first transmission main shaft is rotatably connected to the inner side wall of the air outlet housing. The first transmission shaft is connected to the driving device.

[0010] By adopting the above technical solution, when the occupant in the vehicle adjusts the blowing direction inside the vehicle, the driving device can be used to control the first transmission shaft and the second transmission shaft to adjust the blowing direction of the vehicle-mounted air conditioner. When the first transmission shaft and the second transmission shaft drive the first air door panel and the second air door panel to rotate, when the first connecting shaft is inserted into the second transmission shaft, and when the first transmission shaft and the second transmission shaft rotate, the first connecting shaft is inserted into the second transmission shaft, and the first connecting shaft drives the first transmission shaft and the second transmission shaft to perform a coaxial rotational movement. Therefore, when the first transmission shaft and the second transmission shaft respectively control the rotation of the first air door panel and the second air door panel, only the frictional force between the first connecting shaft and the inner side wall of the second transmission shaft exists between the first transmission shaft and the second transmission shaft, thereby reducing the possibility that the interference occurs during the rotation of the first transmission shaft and the second transmission shaft and affecting the air duct adjustment.

[0011] Optionally, a first sealing glue layer is provided on the side wall of the first air door panel away from the first transmission shaft, and the first air door panel can be rotated to be attached to the air guiding member with the first sealing glue layer; a second sealing glue layer is provided on the side wall of the second air door panel away from the second transmission shaft, and the second air door panel can be rotated to be attached to the air guiding member with the second sealing glue layer.

[0012] By adopting the above technical solution, when the occupant in the vehicle controls the driving device to adjust the first transmission shaft and the second transmission shaft, if it is desired to close one air duct and blow air from the other air duct in the dual-channel air outlet structure of the present application, any one of the first transmission shaft or the second transmission shaft needs to be attached to the air guiding member. Since a pair of opposite side walls of the air guiding member are attached to the inner side wall of the air outlet housing, the cold and hot air can only be blown out from the first air door panel and the second air door panel. Also, since the first air door panel or the second air door panel is attached to the air guiding member, there is an air duct at this time through which the cold and hot air cannot pass. By adopting the structure of the first sealing glue layer and the second sealing glue layer, when any one of the first transmission shaft and the second transmission shaft drives its corresponding air door panel to be attached to the air guiding member, that is, when the corresponding air duct is closed, the corresponding sealing glue layer is attached to the side wall of the air guiding member. Compared with the hard air door panels being attached to the air guiding member, the structure of the sealing glue layer increases the tightness when the air door panel abuts against the air guiding member, reduces the possibility that the cold and hot air blows out between the air door panel and the air guiding member and affects the use experience of the occupant in the vehicle, and improves the comfort of the vehicle-mounted air conditioner applying the dual-channel air outlet structure of the present application.

[0013] Optionally, the driving device includes a driving motor, a driving gear, a driving rack, and a driving plate. The driving plate is disposed on the air outlet housing. The driving motor is disposed on a side of the driving plate away from the air outlet housing and is fixed by a preset external device. The driving gear is disposed at an output end of the driving motor and is rotatably connected to the driving plate. The driving rack is disposed on a side wall of the driving plate close to the driving motor, and the driving gear is engaged with the driving rack. A first guiding groove and a second guiding groove are formed on a side wall of the driving plate away from the driving motor. A first connecting rod is fixedly disposed at one end of the first transmission shaft close to the first guiding groove. The first connecting rod is inserted into the first guiding groove, and the first connecting rod is in contact with an inner side wall of the first guiding groove. A second connecting rod is fixedly disposed at one end of the second transmission shaft close to the first guiding groove. The second connecting rod is inserted into the second guiding groove, and the second connecting rod is in contact with an inner side wall of the second guiding groove. The driving plate is slidably connected to the air outlet housing.

[0014] By adopting the above technical solution, when the vehicle-mounted air conditioner with the dual-channel air outlet structure in the present application is working, the vehicle occupants can control the driving motor to drive the driving gear to rotate around the axis of the driving gear. Therefore, since the driving gear is engaged with the driving rack, and since the driving rack is fixedly connected to the driving plate and the driving motor is fixed by a preset external device, when the driving gear rotates, the driving rack drives the driving plate to start moving in the vertical direction. Since the first guiding groove and the second guiding groove are formed on the side wall of the driving plate away from the driving gear, and the first connecting rod fixedly connected to the first transmission shaft is inserted into the first guiding groove, and the second connecting rod fixedly connected to the second transmission shaft is inserted into the second guiding groove, the shape of the first guiding groove and the second guiding groove can be set so that when the driving plate moves in the vertical direction, the inner side wall of the guiding groove generates a force on the side wall of the connecting rod, thereby causing the connecting rod to drive the transmission rod to rotate, and further causing the transmission rod to drive the air door plate to rotate, so as to realize the adjustment of the air outlet of the first air duct and the second air duct, improving the convenience of the vehicle occupants when adjusting the air duct.

[0015] Optionally, the air outlet housing includes an air outlet main housing and an air outlet connecting housing. The air outlet connecting housing is disposed on a side wall of the air outlet main housing close to the driving motor. The driving plate is inserted into the connecting housing. A sliding groove is formed on a side wall of the driving plate. A sliding block is disposed on an inner side wall of the connecting housing. The sliding block is inserted into the sliding groove, and the sliding block is slidably connected to the sliding groove.

[0016] By adopting the above technical solution, the structure of connecting the air outlet connecting housing and the main air outlet housing is used to realize the installation of the driving motor, and the structure of inserting the sliding block on the air outlet connecting housing into the connecting groove on the driving plate. When the driving motor drives the driving gear and drives the driving plate to move in the vertical direction through the structure of meshing the driving gear with the driving rack, the air outlet connecting housing reduces the possibility of interference between the driving plate and the devices in the main driving housing; and through the cooperation of the sliding block on the air outlet connecting housing and the connecting groove on the driving plate, when the driving plate generates displacement, it is not easy to fall off from the air outlet connecting housing, increasing the stability of the driving plate during operation.

[0017] Optionally, the air guiding member includes an air guiding housing, an air guiding fan and an air guiding driving device. The air guiding housing is inserted into the air outlet housing. A pair of opposite side walls of the air guiding housing are attached to the air outlet housing. The air guiding fan is arranged on the side wall of the air guiding housing through an air guiding shaft. The air guiding shaft is fixedly connected to the air guiding fan. The air guiding shaft is rotatably connected to the air guiding housing. The air guiding driving device is arranged in the air guiding housing and is used to drive the air guiding shaft.

[0018] By adopting the above technical solution, the structure of using the air guiding fan can enable the vehicle-mounted air conditioner to further adjust the air outlet angle of the cold and hot air when blowing air into the vehicle interior. When the cold and hot air blows out from the first air duct or the second air duct, the air outlet angle of the cold and hot air is further adjusted through the inclination angle of the air guiding fan. When it is necessary to adjust the angle of the air guiding fan, the air guiding driving device in the air guiding housing can be controlled to drive the air guiding shaft to rotate. Since the air guiding shaft is fixedly connected to the air guiding fan, when the air guiding driving device drives the air guiding shaft to rotate, the air guiding fan rotates synchronously, so that the angle of the air guiding fan is offset, and further the air outlet angle of the first air duct or the second air duct is adjusted.

[0019] Optionally, the air guiding driving device includes an air guiding motor, a first air guiding push rod, a second air guiding push rod and an air guiding main shaft. The air guiding motor is arranged inside the air guiding housing. The air guiding motor is a reciprocating motor. The first air guiding push rod is arranged at the output end of the air guiding motor. The second air guiding push rod is arranged at the end of the first air guiding push rod away from the air guiding motor. A displacement rod is arranged on the side wall of the first air guiding push rod close to the second air guiding push rod. A displacement groove is formed on the side wall of the second air guiding push rod. The displacement rod is inserted into the displacement groove, and the displacement rod abuts against the inner side wall of the displacement groove. The side wall of the air guiding main shaft is connected to the end of the second air guiding push rod away from the first air guiding push rod. The bottom of the air guiding main shaft is connected to the air guiding shaft.

[0020] By adopting the above technical solution, when the vehicle-mounted air conditioner with the dual-channel air outlet structure in the present application is in use, when the vehicle occupants need to further adjust the air outlet directions of the first air duct and the second air duct, the air guiding motor can be controlled. Since the air guiding motor is a reciprocating motor, the air guiding motor will drive the first air guiding push rod to rotate around the connection point between the reciprocating motor and the first air guiding push rod as the rotation axis. Therefore, when the first air guiding push rod rotates, since the displacement rod arranged on the first air guiding push rod is inserted into the displacement groove on the second air guiding push rod and the displacement rod abuts against the inner side wall of the displacement groove, when the first air guiding push rod makes a reciprocating rotation, a force is generated between the displacement rod and the inner side wall of the displacement groove. Thus, the second air guiding push rod rotates under the action of the displacement rod along with the rotation of the first air guiding push rod. Since the second air guiding push rod is connected to the air guiding main shaft, when the second air guiding push rod rotates, the second air guiding push rod drives the air guiding main shaft to rotate. Therefore, the air guiding main shaft can drive the air guiding shaft to rotate to adjust the direction of the air guiding fan, improving the convenience for vehicle occupants to adjust the air direction.

[0021] Optionally, a plurality of the air guiding fans are provided. One end of each air guiding fan close to the air guiding housing is rotatably connected to the side wall of the air guiding housing. A first connection joint is arranged on the side wall of each air guiding fan. An air guiding connecting rod is arranged in the air outlet housing. A plurality of second connection joints are arranged on the air guiding connecting rod. The first connection joint is rotatably connected to the second connection joint. The air guiding main shaft is connected to any one of the air guiding shafts.

[0022] By adopting the above technical solution, a plurality of air guiding fans enable vehicle occupants to adjust the air outlet directions of the first air duct and the second air duct. Through the structure of the air guiding connecting rod, when the air guiding shaft of one of the air guiding fans is driven by the air guiding main shaft to rotate, the connecting rod can drive all the other air guiding fans to rotate. By synchronously rotating a plurality of air guiding fans, the adjustment of the air outlet angle in the first air duct or the second air duct can be realized. Compared with the structure of using a plurality of air guiding main shafts to drive the same air guiding shaft respectively, the structure of the connecting rod reduces the working energy consumption of the motor and the use cost of the vehicle-mounted air conditioner, saving energy.

[0023] Optionally, the first connection joint and the second connection joint are detachably connected.

[0024] By adopting the above technical solution, the detachable connection structure of the first connection joint and the second connection joint enables the operator to replace the air guiding connecting rod more conveniently. If the structures of the air guiding fan and the air guiding connecting rod become loose between the first connection joint and the second connection joint after long-term use, or the air guiding connecting rod is worn, since the air guiding fans are all driven by a single air guiding main shaft to rotate synchronously, there is a possibility that the air guiding fans may be damaged due to unsmooth rotation between the air guiding fans and the air guiding connecting rod. The detachable connection structure between the first connection joint and the second connection joint enables the operator to replace the air guiding connecting rod at a fixed frequency, reducing the possibility of damage to the air guiding fans caused by damage to the air guiding connecting rod.

[0025] Optionally, a relief groove is formed on the side wall of the second air door plate, and the relief groove is arranged on the side wall of the second air door plate close to the first transmission main shaft.

[0026] By adopting the above technical solution, when the first transmission shaft and the second transmission shaft rotate relative to each other, the structure of the relief groove makes it difficult for the second air door plate to rub against the first transmission main shaft. Therefore, the second air door plate is not easily worn when rotating with the second transmission shaft, improving the overall service life of the system.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. By adopting the structures of the air guiding plate, the first air door plate and the second air door plate, when the dual-channel air outlet structure in the present application is applied to a vehicle-mounted air conditioner, the cold and hot air in the vehicle-mounted air conditioner enters the interior of the air outlet housing from the air intake groove and is separated by the air guiding member, so that the cold and hot air respectively enter the first air duct and the second air duct. When the vehicle occupants want to blow the cold and hot air of the vehicle-mounted air conditioner directly at their bodies to obtain a more comfortable air-conditioning experience, the driving device can be controlled to make the driving device control the rotation of the first transmission shaft and the second transmission shaft, so that the second transmission shaft drives the second air door plate to form a larger angle with the side wall of the air guiding member, while the first transmission shaft drives the first air door plate to form a smaller angle with the side wall of the air guiding member, and even completely fit with the side wall of the air guiding member under the drive of the driving device. As a result, most of the cold air is discharged from between the second air door plate and the side wall of the air guiding member, that is, the second air duct, so that when exhausting air in the vehicle, the situation of directly blowing at the vehicle occupants can be avoided; similarly, when the vehicle occupants feel that the temperature in the vehicle is high but do not need to be directly blown by cold air, the driving device is controlled to make the angle between the first air door plate and the air guiding member larger and the angle between the second air door plate and the air guiding member smaller, so that most of the cold air is blown into the vehicle from between the first air door plate and the side wall of the air guiding member, which not only meets the effect of cooling the vehicle interior but also reduces the possibility of the cold and hot air directly blowing at the vehicle occupants and causing a decrease in the comfort of the vehicle occupants, improving the comfort of the vehicle occupants when using the vehicle-mounted air conditioner.

[0029] 2. The structure of the first air duct door cooperating with the first sealing glue layer and the second air duct door cooperating with the second sealing glue layer is adopted. When the vehicle occupants control the driving device to adjust the first drive shaft and the second drive shaft, if it is desired to close one air duct and let the other air duct blow air in the dual-channel air outlet structure of the present application, any one of the first drive shaft or the second drive shaft needs to be arranged in contact with the air guiding member. Since a pair of opposite side walls of the air guiding member are arranged in contact with the inner side wall of the air outlet housing, the cold and hot air can only be blown out from the first air duct door and the second air duct door. Also, because the first air duct door or the second air duct door is arranged in contact with the air guiding member, there is an air duct at this time through which the cold and hot air cannot pass. By adopting the structure of the first sealing glue layer and the second sealing glue layer, when any one of the first drive shaft and the second drive shaft drives its corresponding air duct door to be in contact with the air guiding member, that is, when the corresponding air duct is closed, the corresponding sealing glue layer is in contact with the side wall of the air guiding member. Compared with the contact between the rigid air duct doors and the air guiding member, the structure of the sealing glue layer increases the tightness when the air duct door and the air guiding member are in contact, reduces the possibility that the cold and hot air is blown out between the air duct door and the air guiding member and affects the use experience of vehicle occupants, and improves the comfort of the vehicle air conditioner adopting the dual-channel air outlet structure of the present application;

[0030] 3. The structure of the first air guiding rod and the second air guiding rod is adopted. When the vehicle air conditioner adopting the dual-channel air outlet structure of the present application is in use, when the vehicle occupants need to further adjust the air outlet directions of the first air duct and the second air duct, they can control the air guiding motor. Since the air guiding motor is a reciprocating motor, the air guiding motor will drive the first air guiding push rod to rotate with the connection point between the reciprocating motor and the first air guiding push rod as the rotation axis. Therefore, when the first air guiding push rod rotates, because the displacement rod arranged on the first air guiding push rod is inserted into the displacement groove on the second air guiding push rod and the displacement rod abuts against the inner side wall of the displacement groove, when the first air guiding push rod makes a reciprocating rotation, the displacement rod generates a force on the inner side wall of the displacement groove, so that the second air guiding push rod rotates with the rotation of the first air guiding push rod under the action of the displacement rod. Since the second air guiding push rod is connected to the air guiding main shaft, when the second air guiding push rod rotates, the second air guiding push rod drives the air guiding main shaft to rotate. Therefore, the air guiding shaft can be driven to rotate through the air guiding main shaft to realize the adjustment of the direction of the air guiding fan, which improves the convenience for vehicle occupants to adjust the air direction.

[0045] The implementation principle of a dual-channel air outlet structure in an embodiment of the present application is as follows: when the dual-channel air outlet structure in the present application is discharging air, when the occupants of the vehicle want the hot and cold air of the vehicle air conditioner to be blown directly toward their bodies so that their bodies can obtain a more comfortable air-conditioning experience, the driving motor 21 can be controlled to drive the driving gear 22 to rotate with the axis of the driving gear 22 as the rotation point. Since the driving gear 22 is meshed with the driving rack 23, and since the driving rack 23 is fixedly connected to the driving plate 24, and the driving motor 21 is fixed by a preset external device, when the driving gear 22 rotates, the driving rack 23 drives the driving plate 24 to start moving in the vertical direction. Since a first guide groove 25 and a second guide groove 26 are provided on the side wall of the driving plate 24 away from the driving gear 22, and a first connecting rod 251 fixedly connected to the first transmission shaft 18 is inserted into the first guide groove 25, and a second connecting rod 261 fixedly connected to the second transmission shaft 19 is inserted into the second guide groove 25. The first and second guide grooves 25 and 26 are in the second guide groove 26. Therefore, the shapes of the first and second guide grooves 25 and 26 can be set so that when the driving plate 24 moves in the vertical direction, the inner side walls of the guide grooves and the side walls of the connecting rod generate a force, so that the connecting rod drives the transmission rod to rotate, and then the transmission rod drives the damper plate to rotate, so that the driving device 2 controls the first transmission shaft 18 and the second transmission shaft 19 to rotate, so that the first transmission shaft 18 or the second transmission shaft 19 drives the first damper plate 16 or the second damper plate 17 to form a larger angle with the side wall of the air guide member 12, and the first transmission shaft 18 or the second transmission shaft 19 is driven by the driving device 2 to drive the first damper plate 16 or the second damper plate 17 to form a smaller angle with the side wall of the air guide member 12, or even completely fit with the side wall of the air guide member 12, so that most of the cold air is discharged from between the first damper plate 16 or the second damper plate 17 and the side wall of the air guide member 12, thereby making it possible to adjust the exhaust angle in the vehicle.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
