Description

Technical Field

[0001] The invention relates to the technical field of automobile air outlets, and more specifically to a dual-channel air outlet. Background Art

[0002] In existing air outlet designs, a single channel or multiple independent channels are usually used; When controlling the air outlet direction, multiple actuators are often required to drive the main air guide blades (left and right air guide blades) and the secondary air guide blades (upper and lower air guide blades) to swing respectively, so as to adjust the left and right wind direction and the up and down wind direction. This not only increases the cost, but also makes the structure complex and occupies a large space.

[0003] At the same time, the air outlet pattern of traditional air outlets is relatively simple, mostly swinging the airflow left and right to expand the air outlet range. The coverage area in the vertical direction is limited, and the airflow mostly blows directly to the user, which has a greater impact on the human body, uneven airflow distribution, and poor user experience. Summary of the invention

[0004] In view of the shortcomings and defects of the prior art, a dual-channel air outlet is provided which reduces the cost and can output a wave-shaped trajectory airflow.

[0005] A dual-channel air outlet, comprising: The air outlet housing is provided with two air outlet channels separated from each other, and the airflows outputted from the two air outlet channels intersect; The secondary air guide blade can swing up and down and is arranged between the air inlet ends of the two air outlet channels to control the air intake volume at the air inlet ends of the air outlet channels, thereby adjusting the up and down air outlet angles; The main wind blade is set in the air outlet channel and can swing left and right to adjust the air outlet angle. A rotating member, driven by an actuator to rotate around an axis A, wherein the rotating member is provided with a first track portion and a second track portion around the axis A; The first track portion has alternately arranged variable diameter sections and first intermittent sections, wherein the variable diameter sections are arranged along an axial variable path, and the first intermittent section has no axial variable path. The second track portion has an adjustment segment and a second intermittent segment which are alternately arranged, wherein the adjustment segment is arranged along a radial change path, the second intermittent segment has no radial change path, and adjacent adjustment segments are arranged with opposite radial change trends; The first linkage member moves along the first track portion and is arranged in linkage with the main wind blade. A second linkage member moves along the second track portion and is arranged in linkage with the secondary wind guide blade; The rotating member rotates, the stroke of the second linkage member in the second intermittent section matches the stroke of the first linkage member in the variable diameter section, the second linkage member drives the secondary air guide blade to be in the intermittent position where the swing is stopped, and the first linkage member drives the main air guide blade to swing left or right. The stroke of the first linkage member in the first intermittent section matches the stroke of the second linkage member in the adjustment section, the first linkage member drives the main airflow blade to be in an intermittent position where the swinging is stopped, and the second linkage member drives the main airflow blade to swing upward or downward; Through the continuous rotation of the rotating part, the main air guide blades and the secondary air guide blades are alternately swung, so that the output airflow forms a wave-shaped trajectory.

[0006] After adopting the above structure, the dual-channel air outlet of the present invention has the following advantages compared with the prior art: The up and down swing of the secondary air guide blade can control the opening of the air inlet end of the air outlet channel, thereby controlling the air intake volume. When the air intake volumes of the two air outlet channels are the same, the two air flows meet and are output at a preset angle. When the air intake of one of the air outlet channels is less than the air intake of the other air outlet channel, the two air flows converge and tend to be output in the direction of the air flow output from the air outlet channel with the larger air intake.

[0007] The first track portion of the rotating member drives the main air guide blade to swing left and right through the first linkage member to adjust the left and right air outlet angles, and the second track portion drives the secondary air guide blade to swing up and down through the second linkage member to adjust the up and down air outlet angles. The main air guide blade enters an intermittent position where it stops swinging after each angle is adjusted. At this time, the rotating part continues to rotate, which can drive the secondary air guide blade to swing upward and downward. The air outlet direction can be adjusted up and down in multiple left and right air outlet angles.

[0008] Compared with the traditional air outlet that uses two actuators to drive the main air guide blade and the secondary air guide blade to swing respectively to adjust the left and right wind direction and the up and down wind direction, this device only uses one actuator to achieve left and right wind direction adjustment and up and down wind direction adjustment, which greatly reduces the cost.

[0009] The device also has a wave-shaped trajectory wind outlet mode: through the continuous rotation of the rotating member, the main wind blade and the secondary wind guide blade are alternately swung, so that the output airflow forms a wave-shaped trajectory.

[0010] Compared with the traditional air outlet that outputs left-right swinging air flow to expand the air outlet range, the wavy air outlet trajectory of this device can cover a larger area in the vertical direction, and the air flow does not blow directly to the user, but blows to the user in a sweeping manner, reducing the direct impact on the human body and improving the user experience.

[0011] As an improvement of the present invention, the first track portion is a groove structure and is arranged on the circumference of the rotating member; The first linkage member is a transmission pin extending into the first track portion.

[0014] As an improvement of the present invention, there are multiple main air flow blades in each of the air outlet channels, and they are arranged at intervals along the left and right directions of the air outlet channels. The multiple main air flow blades are interconnected by connecting rods, and a driven gear is arranged on the central axis of one of the main air flow blades.

[0015] As an improvement of the present invention, the first track portion includes, in sequence along the first direction, a diameter-changing section a, a first intermittent section b, a diameter-changing section c, a first intermittent section d, a diameter-changing section e, a first intermittent section f, a diameter-changing section g, and a first intermittent section h; Each variable diameter section is arranged in a leftward changing trajectory along the first direction, and each first intermittent section is arranged in a front-to-back straight non-variable diameter structure; In the initial position state, the first linkage member is at the head end of the variable diameter section a, and drives the main wind blade to swing to a position to close the air outlet channel. The rotating member rotates along the second direction, and the main wind blade swings to a position to open the air outlet channel.

[0016] As an improvement of the present invention, the second track portion includes a second intermittent segment aa, an adjustment segment bb, a second intermittent segment cc, an adjustment segment dd, a second intermittent segment ee, an adjustment segment ff, a second intermittent segment gg, and an adjustment segment hh in sequence along the first direction; In the initial position state, the second linkage member is located at the head end of the second intermittent section aa, and drives the secondary air guide blade to be in the reference position state. When the secondary air guide blade is in the reference position state, the air intake volume at the air inlet end of the two air outlet channels is consistent, and the rotating member rotates along the second direction, driving the secondary air guide blade to swing upward or downward alternately.

[0017] As an improvement of the present invention, the air outlet housing is provided with two groups of air outlet channels which are bilaterally symmetrical, each of the two groups of air outlet channels is provided with a main air guide blade, and each of the two groups of air outlet channels is provided with a secondary air guide blade between the air inlet ends; The main air guide blades and the secondary air guide blades of the two sets of air outlet channels are driven by independent rotating parts; The two rotating members are coaxially arranged, and the first track portions of the two rotating members are arranged in a left-right symmetrical structure, and the second track portions of the two rotating members are arranged in a parallel structure.

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 ,as well as Fig.11 As shown, in Figure 2 The red lines in the figure indicate the intersection path of the airflows of the two air outlet channels 1.1. Fig.11 The red lines in the figure represent the wavy airflow trajectory output by a single set of air outlet channels.

[0034] A dual-channel air outlet, comprising: The air outlet housing 1 is provided with two air outlet channels 1.1 separated from each other in an upper and lower direction, and the airflows outputted from the two air outlet channels 1.1 intersect; The secondary air guide blade 2 is arranged between the air inlet ends of the two air outlet channels 1.1 and can swing up and down. The secondary air guide blade 2 swings up and down to control the opening of the air inlet end of the air outlet channel 1.1, thereby controlling the air intake volume. When the air intake volumes of the two air outlet channels 1.1 are the same, the two air flows meet and are output at a preset angle. When the air intake of one of the air outlet channels 1.1 is smaller than the air intake of the other air outlet channel 1.1, the two air flows converge and tend to be output in the direction of the air flow output from the air outlet channel 1.1 with the larger air intake.

[0035] The main wind blade 3 is arranged in the air outlet channel 1.1 and can swing left and right to adjust the air outlet angle left and right; The rotating member 4 is driven by the actuator 4.1 to rotate around the axis A. The rotating member 4 is provided with a first track portion 5 and a second track portion 6 around the axis A; The first track portion 5 has alternately arranged variable diameter sections and first intermittent sections, wherein the variable diameter sections are arranged along the axial variable path, and the first intermittent section has no axial variable path. The second track portion 6 has an adjustment section and a second intermittent section that are alternately arranged, wherein the adjustment section is arranged along a radial change path, the second intermittent section has no radial change path, and adjacent adjustment sections are arranged with opposite radial change trends; The first linkage member 7 moves along the first track portion 5 and is arranged in linkage with the main wind blade 3. The second linkage member 8 moves along the second track portion 6 and is arranged in linkage with the secondary wind guide blade 2; The rotating member 4 rotates, the stroke of the second linkage member 8 in the second intermittent section matches the stroke of the first linkage member 7 in the diameter-changing section, the second linkage member 8 drives the secondary air guide blade 2 to be in the intermittent position where the swinging is stopped, and the first linkage member 7 drives the main air guide blade 3 to swing leftward or rightward. The stroke of the first linkage member 7 in the first intermittent section matches the stroke of the second linkage member 8 in the adjustment section. The first linkage member 7 drives the main wind blade 3 to be in the intermittent position where the swinging stops, and the second linkage member 8 drives the main wind blade 3 to swing upward or downward. By continuously rotating the rotating member 4, the main air guide blades 3 and the secondary air guide blades 2 are alternately swung, so that the output airflow forms a wave-shaped trajectory.

[0036] The first track portion 5 provided on the rotating member 4 drives the main air guide blade 3 to swing left and right through the first linkage member 7 to adjust the left and right air outlet angles, and the second track portion 6 provided drives the secondary air guide blade 2 to swing up and down through the second linkage member 8 to adjust the up and down air outlet angles. The main air guide blade 3 enters an intermittent position where it stops swinging after each angle adjustment. At this time, the rotating member 4 continues to rotate, which can drive the secondary air guide blade 2 to swing upward and downward, and the air outlet direction can be adjusted up and down in multiple left and right air outlet angles.

[0037] Compared with the conventional air outlet which uses two actuators 4.1 to respectively drive the main air guide blade 3 and the secondary air guide blade 2 to swing and adjust the left and right wind direction and the up and down wind direction, the present device uses only one actuator 4.1 to achieve left and right wind direction adjustment and up and down wind direction adjustment, which greatly reduces the cost.

[0038] The device also has a wave-shaped air outlet mode: through the continuous rotation of the rotating member 4, the main air guide blades 3 and the secondary air guide blades 2 are alternately swung, so that the output airflow forms a wave-shaped trajectory.

[0039] Compared with the traditional air outlet that outputs left-right swinging air flow to expand the air outlet range, the wavy air outlet trajectory of this device can cover a larger area in the vertical direction, and the air flow does not blow directly to the user, but blows to the user in a sweeping manner, reducing the direct impact on the human body and improving the user experience.

[0040] See also Figure 3 , Figure 4 ,as well as Figure 5 As shown: The first track portion 5 is a groove structure and is arranged on the circumference of the rotating member 4; The first linkage member 7 is a transmission pin extending into the first track portion 5. The transmission pin moves left and right when the first track portion 5 travels, and when the transmission pin moves left and right, it drives the main wind blade 3 to swing left and right through the transmission mechanism.

[0041] The first track portion 5 is designed as a groove structure and is disposed on the peripheral surface of the rotating member 4, so that the axial diameter reduction processing can be performed relatively directly and simply.

[0042] The second track portion 6 is a groove structure and is arranged on the axial end surface of the rotating member 4; The rotating shaft of the secondary air guide blade 2 is arranged parallel to the axis A of the rotating member 4, and a coaxial crank 2.1 is arranged at one end of the rotating shaft of the secondary air guide blade 2; The second linkage member 8 is a crank pin arranged on the crank 2 . 1 , and the crank pin extends into the second track portion 6 .

[0043] The second track portion 6 is designed as a groove structure and is arranged on the axial end surface of the rotating member 4. It is distributed on a different surface of the rotating member 4 from the first track portion 5, which has the characteristics of reasonable structural layout and can directly and simply perform radial diameter reduction processing. The crank pin moves along the second track portion 6, driving the crank 2.1 to rotate, thereby driving the secondary wind guide blade 2 to swing up and down. Compared with the traditional transmission structure using connecting rods or multi-stage gears, the present application has the characteristics of simple structure, fewer parts, low cost, and stable and reliable operation.

[0044] In addition, the groove structure is tightly integrated with the pin, which can accurately control the main wind guide blades and the secondary wind guide blades to swing according to a preset rule.

[0045] See also Figure 4 , Figure 5 As shown: The transmission mechanism includes a moving member 9, a shift fork 10, and a transmission frame 11. The first linkage member 7 is arranged on the moving member 9. The moving member 9 is guided by a guide structure arranged on the air outlet housing 1 to move left and right. After the moving member 9 is connected to the first linkage member 7, the first linkage member 7 can also be guided and move left and right only under the driving action of the first track portion 5. The shift fork 10 is arranged on the moving member 9, the transmission frame 11 is located between the two air outlet channels 1.1, and the rear end of the transmission frame 11 is rotatably connected to the air outlet housing 1, and the front end is transmission-connected to the shift fork 10. When the moving member 9 translates left and right, the shift fork 10 drives the transmission frame 11 to rotate left and right; The upper and lower ends of the transmission frame 11 are respectively provided with driving gears 11.1, wherein the upper driving gear 11.1 is meshedly connected with the driven gear 3.1 at the lower end of the central axis of the main air-flow blade 3 in the upper air outlet channel 1.1, and the lower driving gear 11.1 is meshedly connected with the driven gear 3.1 at the upper end of the central axis of the main air-flow blade 3 in the lower air outlet channel 1.1.

[0046] The transmission mechanism converts the left-right translation of the first linkage member 7 into the left-right translation of the moving member 9, the left-right translation of the shift fork 10 and the left-right rotation of the transmission frame 11, and finally realizes the left-right swing of the main wind blade 3 through the gear transmission structure.

[0047] The main air flow blades 3 in the two air outlet channels 1.1 are controlled separately, and the swing angle and speed of the main air flow blades 3 can be accurately controlled, so that the structure is further optimized, the structure is simpler, and the cost is further reduced.

[0048] See also Figure 2 , Figure 3 ,as well as Figure 5 As shown: There are multiple main air guide blades 3 in each air outlet channel 1.1, and they are arranged at intervals along the left and right directions of the air outlet channel 1.1. The multiple main air guide blades 3 are interconnected through connecting rods, and a driven gear 3.1 is set on the central axis of one of the main air guide blades 3.

[0049] A plurality of main air flow blades 3 are arranged in each air outlet channel 1.1, and are linked by connecting rods. A driven gear 3.1 is arranged on the central axis of only one of the main air flow blades 3. The driven gear 3.1 is meshed with the driving gear 11.1 to realize the overall movement of the plurality of main air flow blades 3, which further simplifies the structure and makes the device more compact. In addition, the plurality of main wind guiding blades 3 swing synchronously (with the same swing angle), which has the same airflow guiding effect and reduces turbulence.

[0050] See also Figure 4 , Figure 6-Figure 9 As shown: The first track portion 5 includes, in sequence along the first direction, a diameter-changing section a, a first intermittent section b, a diameter-changing section c, a first intermittent section d, a diameter-changing section e, a first intermittent section f, a diameter-changing section g, and a first intermittent section h; Each variable diameter section is arranged in a leftward changing trajectory along the first direction, and each first intermittent section is arranged in a front-to-back straight non-variable diameter structure; In the initial position state, the first linkage member 7 is at the head end of the variable diameter section a, and drives the main wind blade 3 to swing to the position of closing the air outlet channel 1.1. The rotating member 4 rotates along the second direction, and the main wind blade 3 swings to the position of opening the air outlet channel 1.1.

[0051] After the above improvement, the head end of the variable diameter section a is used as the starting point of the first track portion 5. If the first linkage member 7 is at the head end of the variable diameter section a, the main wind blade 3 is at this time in the swing direction (rightward) of closing the air outlet channel 1.1 to the position of closing the air outlet channel 1.1; Furthermore, if the rotating member 4 rotates along the second direction, the first linkage member 7 moves in sequence along the variable diameter section a, the first intermittent section b, the variable diameter section c, the first intermittent section d, the variable diameter section e, the first intermittent section f, the variable diameter section g, and the first intermittent section h, and the main wind blade 3 swings in the swinging direction (to the left) to open the air outlet channel 1.1. In the present application, the variable diameter section a is used to drive the first linkage member 7 to have a position to close the air outlet channel, so that the air outlet channel 1.1 can be closed, and the airflow cannot be output, and external debris is prevented from entering the air outlet channel 1.1.

[0052] See also Figure 4 , Figure 6-Figure 11 As shown: The second track portion 6 includes, in sequence along the first direction, a second intermittent segment aa, an adjustment segment bb, a second intermittent segment cc, an adjustment segment dd, a second intermittent segment ee, an adjustment segment ff, a second intermittent segment gg, and an adjustment segment hh; In the initial position state, the second linkage member 8 is located at the head end of the second intermittent segment aa, and drives the secondary air guide blade 2 to be in the reference position state. When the secondary air guide blade 2 is in the reference position state, the air intake volume at the air inlet end of the two air outlet channels 1.1 is consistent, the rotating member 4 rotates along the second direction, and the second linkage member 8 moves along the second intermittent segment aa, the adjustment segment bb, the second intermittent segment cc, the adjustment segment dd, the second intermittent segment ee, the adjustment segment ff, the second intermittent segment gg, and the adjustment segment hh in sequence, driving the secondary air guide blade 2 to swing upward or downward alternately.

[0053] The second intermittent section aa matches the stroke of the variable diameter section a, the adjustment section bb matches the stroke of the first intermittent section b, the second intermittent section cc matches the stroke of the variable diameter section c, the adjustment section dd matches the stroke of the first intermittent section d, the second intermittent section ee matches the stroke of the variable diameter section e, the adjustment section ff matches the stroke of the first intermittent section f, the second intermittent section gg matches the stroke of the variable diameter section g, and the adjustment section hh matches the stroke of the variable diameter section h.

[0054] In the present application, the continuous rotation of the rotating member 4 can be reciprocating rotation along the first direction and the second direction, so that the first linkage member 7 can travel along a specific stroke segment of the first track portion 5, and the second linkage member 8 can travel along a specific stroke segment of the second track portion 6. The stroke segment can be composed of a plurality of alternating variable diameter segments, a first intermittent segment, and a plurality of alternating adjustment segments, a second intermittent segment, thereby outputting an airflow with a wavy trajectory that circulates back and forth in a specific area.

[0055] See also Figure 1 , Figure 2 ,as well as Figure 3 As shown: The air outlet housing 1 is provided with two groups of air outlet channels 1.1 which are symmetrical on both sides. A main air guide blade 3 is provided in each of the two groups of air outlet channels 1.1, and a secondary air guide blade 2 is provided between the air inlet ends of the two groups of air outlet channels 1.1. The main air guide blades 3 and the secondary air guide blades 2 of the two sets of air outlet channels 1.1 are driven by an independent rotating member 4; The two rotating members 4 are coaxially arranged, and the first track portions 5 of the two rotating members 4 are arranged in a left-right symmetrical structure, and the second track portions 6 of the two rotating members 4 are arranged in a parallel structure.

[0056] Among them, the rotating member 4 at the left position has a variable diameter section that changes diameter to the left along the first direction, and the linked main wind blade 3 swings to the right to close the air outlet channel 1.1 and to the left to open the air outlet channel 1.1.

[0057] The rotating member 4 at the right position has a diameter-changing section that changes diameter to the right along the first direction. The linked main wind blade 3 swings to the left to close the air outlet channel 1.1 and to the right to open the air outlet channel 1.1.

[0058] The two rotating members 4 rotate synchronously.

[0059] The main air blades 3 of the two groups of air outlet channels 1.1 swing inwards or outwards symmetrically to have a direct blowing air outlet state, a concentrated air outlet state, and a diffused air outlet state.

[0060] After the above improvements, when the two sets of main wind blades 3 of the device swing to tilt to the left and right sides, the wind outlet area can be expanded to diffuse the wind; When the two sets of main wind blades 3 swing to the middle position of the air outlet housing 1, the air can be discharged in a concentrated manner to obtain a concentrated air outlet state; When the two groups of main wind blades 3 swing to be parallel to each other, the air can be blown out directly.

[0061] The rotating member 4 is arranged on the outside of the air outlet housing 1 , and a mounting frame is arranged on the outside of the air outlet housing 1 for assembling the actuator 4 . 1 .

[0062] The rotating part 4 is arranged on the outside of the air outlet shell 1 and equipped with an outer mounting frame to assemble the actuator 4.1, which facilitates installation, debugging, and maintenance, and does not occupy the limited space in the air outlet shell 1, is conducive to the optimized layout of the internal air duct structure and other components, and improves the rationality and compactness of the overall structure of the air outlet.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
