Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning vent technology, and more specifically to a multi-channel interconnected air vent. Background Technology

[0002] Car air conditioning vents are interior components of a car, typically located in the driver's cabin or diagonally above the passenger seat. The vent's air duct is connected to a device that provides airflow. When airflow is needed, the device delivers airflow to the duct, and the airflow is discharged from the vent's outlet.

[0003] In the prior art, the air outlet duct of a car air conditioner is generally equipped with upper and lower air guide vanes and left and right air guide vanes. The upper and lower air guide vanes are used to adjust the vertical air outlet direction, and the left and right air guide vanes are used to adjust the horizontal air outlet direction. The required air guide vanes are driven to rotate by a drive mechanism, thereby adjusting the direction of the output airflow.

[0004] The aforementioned air outlet duct has many components, and the blades require a lot of space, which is not conducive to the miniaturization of the device and results in a poor user experience. Summary of the Invention

[0005] In view of the shortcomings and defects of the prior art, this application receives airflow through an air outlet duct and outputs it, and the outlet of the air outlet duct is deflectable to adjust the direction of airflow output, which has the characteristics of simple structure and wide adjustment range.

[0006] A multi-channel interconnected air outlet, comprising:

[0007] The air outlet housing is equipped with an air outlet channel;

[0008] The air outlet duct is hinged to the air outlet housing and has a flow channel that communicates with the air outlet channel. One end of the flow channel receives the airflow in the air outlet channel and the other end outputs the airflow. Moving the air outlet duct can cause the opening to deflect to adjust the direction of airflow output.

[0009] Linkage components, and drive assemblies that drive the linkage components to move along the X-axis and along the Y-axis.

[0010] The linkage is hinged to one end of the air outlet in the front-to-back direction. When the linkage moves, it can drive the air outlet to move.

[0011] With the above structure, the multi-channel linkage air outlet of the present invention has the following advantages compared with the prior art:

[0012] In use, the airflow enters the air outlet channel from the air outlet duct, and then exits through the outlet at the other end of the channel.

[0013] Furthermore, when it is necessary to adjust the airflow direction, the linkage can be moved by the drive component, which in turn drives the air outlet to move.

[0014] The movement method is as follows: the linkage can move along the X-axis and along the Y-axis to deflect the outlet of the air duct along the X-axis and Y-axis, thereby adjusting the output direction of the outlet in any direction, up, down, left, or right.

[0015] Compared with existing air outlet devices, this application can achieve multiple air direction adjustments with a single air outlet duct. It has a simple structure, a wider air direction adjustment angle, and requires less installation space, making it suitable for installation in cars with limited space.

[0016] As an improvement of the present invention, the air outlet duct is a tubular structure extending front and rear.

[0017] The air outlet has a first spherical structure on its outer periphery.

[0018] The air outlet housing is provided with a first spherical groove, and a first spherical structure is embedded in the first spherical groove to form a first spherical pair.

[0019] As an improvement of the present invention, the linkage is placed at the tail end of the air outlet, and the air outlet is hinged to the linkage, wherein the hinge structure and the first spherical pair are spaced apart in the front-rear direction.

[0020] As an improvement of the present invention, one end of the linkage is provided with a transmission hole that runs through the front and rear.

[0021] The drive assembly includes a transmission component, and the transmission component is provided with the following sequentially arranged from its front end to its rear end:

[0022] The input section is used to receive external torque;

[0023] The connecting part is hinged to the fixed fulcrum of the air outlet housing through a universal hinge structure, so that the transmission component can swing in two dimensions around the fixed fulcrum.

[0024] And an output part, inserted into the transmission hole, with a gap between the output part and the wall of the transmission hole for swinging;

[0025] When a torque is applied to the input section, the transmission component swings around the fixed fulcrum in the X and Y axis directions, thereby driving the linkage component to move through the output section.

[0026] As an improvement of the present invention, the universal hinge structure includes a rotating member disposed on the air outlet housing and capable of rotating along the X-axis.

[0027] The linkage is located inside the rotating component and is connected to the rotating component via a pin, allowing it to rotate along the Y-axis.

[0028] As an improvement of the present invention, the drive assembly further includes a first linkage gear.

[0029] The first linkage gear is connected to a crank via a first clutch.

[0030] The crank's rotation axis is perpendicular to both the X-axis and the Y-axis;

[0031] The crank tail end is hinged to the input section via a second spherical joint.

[0032] When the first clutch is engaged, the first linkage gear rotates, which drives the crank to rotate, thereby driving the transmission component to oscillate in two dimensions.

[0033] As an improvement of the present invention, the drive assembly further includes an actuator and an output gear.

[0034] The output gear is driven to rotate by the actuator, and the output gear is connected to the first linkage gear in a transmission connection.

[0035] As an improvement of the present invention, the air outlet channel is provided with an adjustable air volume blade.

[0036] The airflow blades have a cylindrical structure and are provided with radially penetrating adjustment channels.

[0037] The air outlet channel has semi-circular grooves at opposite positions on its upper and lower side walls.

[0038] The airflow blades fit within a cylindrical contoured space formed by two receiving slots.

[0039] Initially, adjust the channel position to maximize overlap with the air outlet channel, ensuring the air outlet channel receives maximum airflow.

[0040] The airflow blades rotate up and down, changing the overlap area between the adjustment channel and the groove, thereby controlling the airflow.

[0041] As an improvement of the present invention, the airflow blades are provided with a coaxial rotating shaft, and the rotating shaft is provided with an input gear.

[0042] The input gear and the output gear are connected in a transmission manner.

[0043] As an improvement of the present invention,

[0044] The output gear is meshed with an intermediate gear.

[0045] The input gear is meshed with a transmission gear, and the transmission gear is connected to a second linkage gear via a second clutch.

[0046] The intermediate gear meshes with the first linkage gear and the second linkage gear respectively. Attached Figure Description

[0055] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0056] Please see Figure 1-7 As shown, a multi-channel linked air outlet includes:

[0057] The air outlet housing 1 is provided with an air outlet channel 1.1;

[0058] The air outlet duct 2 is hinged to the air outlet housing 1 and has a flow channel 2.1 that communicates with the air outlet channel 1.1. One end of the flow channel 2.1 receives the airflow in the air outlet channel 1.1 and the other end outputs the airflow. Moving the air outlet duct 2 can cause the opening to deflect to adjust the direction of airflow output.

[0059] Linkage component 3, and the drive assembly that drives linkage component 3 to move along the X-axis and along the Y-axis.

[0060] Linkage component 3 is hinged to one end of the air outlet duct 2 in the front-to-back direction. When linkage component 3 moves, it can drive the air outlet duct 2 to move.

[0061] In use, the airflow enters the flow channel 2.1 of the air outlet duct 2 from the air outlet channel 1.1, and is then output through the outlet 2.11 at the other end of the flow channel 2.1.

[0062] Furthermore, when it is necessary to adjust the airflow direction, the linkage 3 can be moved by the drive component, which in turn drives the air outlet 2 to move.

[0063] The movement mode is as follows: the linkage 3 can move along the X-axis and along the Y-axis to deflect the outlet of the air duct 2 along the X-axis and Y-axis, thereby adjusting the output direction of the outlet 2.11 in any direction, up, down, left, or right.

[0064] Compared with existing air outlet devices, this application can achieve multiple air direction adjustments with a single air outlet 2. It has a simple structure, a wider air direction adjustment angle, and requires a shallower assembly space for installation, making it suitable for installation in cars with limited space.

[0065] Please see Figure 2-4 As shown, the air outlet duct 2 is a tubular structure extending front and back. The tubular flow channel 2.1 reduces the resistance changes during airflow and improves the ventilation performance of the air outlet.

[0066] In some embodiments, the length of the air outlet duct 2 can be designed to be relatively short, further reducing the space occupied and facilitating the miniaturization of the device.

[0067] The air outlet duct 2 has a first spherical structure 2.2 formed on its outer periphery.

[0068] The air outlet housing 1 is provided with a first spherical groove 1.2, and a first spherical structure 2.2 is embedded in the first spherical groove 1.2 to form a first spherical pair, so that the air outlet duct 2 can flexibly deflect, thereby enabling precise and wide-range multi-directional adjustment of the airflow output direction.

[0069] In some embodiments, the center of the first spherical structure 2.2 coincides with the center of the air outlet 2, making the structural layout more reasonable.

[0070] Linkage component 3 is located at the tail end of air outlet duct 2, and air outlet duct 2 is hinged to linkage component 3.

[0071] In some embodiments, the upper and lower surfaces of the tail end of the air outlet duct 2 may be provided with spherical pins 2.3, and the linkage 3 is provided with a spherical seat 4 into which the spherical pins 2.3 can enter, so as to realize the hinge connection between the air outlet duct 2 and the linkage 3. The above improvement hides the linkage structure inside the air outlet housing 1, improving the aesthetics and compactness of the device.

[0072] In some embodiments, the hinge structure and the first spherical pair are spaced apart in the front-rear direction, and there is a long distance between the two hinge points. Therefore, the linkage 3 can drive the air duct 2 to deflect stably and at a large angle, which can achieve a wider range of air outlet angle adjustments.

[0073] Please see Figure 4-6 As shown, one end of the linkage 3 is provided with a transmission hole 3.1 that runs through the front and rear;

[0074] In some embodiments, the drive assembly may be a cylindrical transmission component 5.

[0075] The transmission component 5 is provided with the following features along its upper edge from front to rear:

[0076] Input unit 5.1 is used to receive external torque;

[0077] The connecting part 5.2 is hinged to the fixed fulcrum of the air outlet housing 1 through a universal hinge structure, so that the transmission part 5 can swing in two dimensions around the fixed fulcrum.

[0078] The output part 5.3 is inserted into the transmission hole 3.1, and a gap is left between the output part 5.3 and the wall of the transmission hole 3.1 to allow for swinging, so as to avoid jamming and make the device operate more stably.

[0079] When torque is applied to the input section 5.1, the transmission member 5 swings in two dimensions around the fixed fulcrum in the X and Y axis directions, thereby driving the linkage member 3 and the air outlet duct 2 to move through the output section 5.3;

[0080] The above-mentioned structural arrangement is characterized by its simple structure, stable and reliable operation, and high degree of space compactness.

[0081] In some embodiments, the universal hinge structure includes a rotating member 6 disposed on the air outlet housing 1 and rotatable along the X-axis. The rotating member 6 is a ring structure, and the outer periphery of the rotating member 6 is hinged to the air outlet housing 1.

[0082] The linkage 3 is located in the middle of the inner side of the rotating part 6, and its outer circumference is connected to the hole on the inner circumference of the rotating part 6 through the pin 5.4, and can rotate along the Y-axis;

[0083] The above improvements enable the transmission component 5 to perform two-dimensional oscillation.

[0084] In some embodiments, the drive assembly further includes a first linkage gear 7.

[0085] The first linkage gear 7 is connected to the crank 7.1 via the first clutch 7.2.

[0086] The rotation axis 9.2 of crank 7.1 is set perpendicular to the X-axis and the Y-axis;

[0087] The tail end of crank 7.1 is hinged to input section 5.1 via a second spherical joint.

[0088] When the first clutch 7.2 is engaged, the first linkage gear 7 rotates, which drives the crank 7.1 to rotate, thereby driving the transmission component 5 to oscillate in two dimensions.

[0089] When the first clutch 7.2 is disengaged, the first linkage gear 7 rotates, but cannot drive the crank 7.1 to rotate. The position of the transmission component 5 remains unchanged, and the position of the air outlet duct 2 remains unchanged through the linkage component 3.

[0090] In some embodiments, the crank 7.1 is configured with an inclined structure, and the angle α between its extension path and the shaft of the crank 7.1 is 65°.

[0091] In some embodiments, the drive assembly may be an electric drive assembly, such as actuator 8 and output gear 8.1.

[0092] The output gear 8.1 is driven to rotate by the actuator 8, and the output gear 8.1 is connected to the first linkage gear 7 in a transmission connection.

[0093] Please see Figure 2 As shown, the air outlet duct 1.1 is equipped with an adjustable airflow vane 9.

[0094] The air volume blade 9 has a cylindrical structure and is equipped with a radially penetrating adjustment channel 9.1.

[0095] The end of the air outlet duct 1.1 is connected to the air supply component, and the airflow will pass through the aforementioned regulating duct 9.1 after entering;

[0096] The air outlet duct 1.1 has semi-circular grooves 1.11 at opposite positions on its upper and lower side walls.

[0097] The air volume blade 9 fits into the cylindrical contoured space formed by the two receiving slots, thus enabling the air volume blade 9 to rotate up and down.

[0098] Initially, the adjustment channel 9.1 is positioned to maximize its overlap with the air outlet channel 1.1, ensuring that the air outlet channel 1.1 receives the maximum airflow.

[0099] If the air volume needs to be adjusted, the air volume blade 9 can be rotated up and down to change the overlapping area of ​​the adjustment channel 9.1 and the groove 1.11, thereby controlling the air volume. When the adjustment channel 9.1 rotates to the point where the overlapping area decreases, the air volume entering the outlet channel 1.1 is reduced.

[0100] Please see Figure 4 The air volume vanes 9 shown are sequentially equipped with coaxial rotating shafts 9.2, and the rotating shafts 9.2 are equipped with input gears 9.21.

[0101] The input gear 9.21 is connected to the output gear 8.1 in a transmission manner;

[0102] After the above improvements, the first clutch 7.2 is in a disengaged state. At this time, the actuator 8 drives the output gear 8.1 to rotate, which can drive the input gear 9.21 to rotate, thereby causing the air volume blades 9 to rotate up and down to adjust the air volume.

[0103] In some embodiments, the output gear 8.1 is meshed with the intermediate gear 10.

[0104] The input gear 9.21 is meshed with the transmission gear 11, and the transmission gear 11 is connected to the second linkage gear through the second clutch 12.

[0105] The intermediate gear 10 is meshed with the first linkage gear 7 and the second linkage gear respectively.

[0106] In the above embodiments, a second clutch 12 is also provided in the transmission path between the air volume blade 9 and the actuator 8 to establish or disconnect the transmission connection, so that the air volume adjustment and the air direction adjustment can operate independently without affecting each other, thereby further improving the reliability of the device operation.

[0107] In some embodiments, there are multiple air outlets 2, which are arranged along the X-axis and are hinged to the same linkage 3. When the linkage 3 moves, it can drive the multiple air outlets 2 to move synchronously, which can expand the coverage of the airflow and ensure good consistency of the airflow direction within the air outlet range, resulting in a more comfortable user experience.

[0108] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
