Description

Technical Field

[0001] The present invention relates to the technical field of automotive air vents, and more precisely, to a dual-channel air vent. Background Art

[0002] In the existing air vent designs, single channels or multiple independent channels are usually adopted;

[0003] When controlling the air outlet direction, multiple actuators are often required to drive the main air guiding vanes (left and right air guiding vanes) and secondary air guiding vanes (up and down air guiding vanes) to swing respectively to achieve the adjustment of the left and right air directions and up and down air directions. This not only increases the cost, but also makes the structure complex and occupies a large space.

[0004] At the same time, the air outlet mode of traditional air vents is relatively single. Mostly, the air flow swings left and right to expand the air outlet range. The coverage area in the vertical direction is limited, and the air flow mostly blows directly at the user, causing a large impact on the human body, uneven air flow distribution, and poor user experience. Summary of the Invention

[0005] Aiming at the deficiencies and defects of the prior art, a dual-channel air vent that reduces costs and can output an air flow with a wavy trajectory is provided.

[0006] A dual-channel air vent includes:

[0007] An air vent housing provided with two vertically separated air outlet channels, and the air flows output by the two air outlet channels intersect;

[0008] Secondary air guiding vanes are arranged between the air inlet ends of the two air outlet channels and can swing up and down 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;

[0009] Main air guiding vanes are arranged in the air outlet channels and can swing left and right to adjust the left and right air outlet angles;

[0010] A rotating member is driven by an actuator to rotate around axis A, and the rotating member is provided with a first trajectory portion and a second trajectory portion around axis A;

[0011] The first trajectory portion has alternately arranged variable diameter segments and first intermittent segments. Among them, the variable diameter segments are arranged along the axial change path, and the first intermittent segments are arranged without an axial change path.

[0012] The second trajectory portion has alternately arranged adjustment segments and second intermittent segments. Among them, the adjustment segments are arranged along the radial change path, the second intermittent segments are arranged without a radial change path, and adjacent adjustment segments are arranged with opposite radial change trends;

[0013] A first linkage member travels along the first trajectory portion and is linked with the main air guiding vanes.

[0014] The second linkage member travels along the second track portion and is linked with the secondary air guide vane;

[0015] When 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 diameter-changing section. The second linkage member drives the secondary air guide vane to be in the intermittent position where it stops swinging, and the first linkage member drives the main air guide vane to swing left or right.

[0016] 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 air guide vane to be in the intermittent position where it stops swinging, and the second linkage member drives the main air guide vane to swing up or down;

[0017] Through the continuous rotation of the rotating member, the alternating swinging of the main air guide vane and the secondary air guide vane is realized, so that the output air flow forms a wavy trajectory.

[0018] After adopting the above structure, a dual-channel air outlet of the present invention has the following advantages compared with the prior art:

[0019] The up-and-down swinging of the secondary air guide vane can control the opening degree of the air inlet end of the air outlet channel, and thus control the air intake volume. When the air intake volumes of the two air outlet channels are the same, the two air flows converge and are output at a preset angle;

[0020] When the air intake volume of one of the air outlet channels is less than that of the other air outlet channel, the two air flows converge and tend to be output in the air flow direction of the air outlet channel with a larger air intake volume.

[0021] The first track portion provided on the rotating member drives the main air guide vane to swing left and right through the first linkage member to adjust the left and right air outlet angles, and the provided second track portion drives the secondary air guide vane to swing up and down through the second linkage member to adjust the up and down air outlet angles.

[0022] After the main air guide vane finishes adjusting at each angle and enters the intermittent position where it stops swinging, at this time, when the rotating member continues to rotate, it can drive the secondary air guide vane to swing up and down, and the air outlet direction can be adjusted up and down among multiple left and right air outlet angles.

[0023] Compared with the traditional air outlet that uses two actuators to drive the main air guide vane and the secondary air guide vane to swing respectively for left and right wind direction and up and down wind direction adjustment, this device only uses one actuator to achieve left and right wind direction adjustment and up and down wind direction adjustment, and the cost is greatly reduced.

[0024] This device also has an air outlet mode with a wavy trajectory: through the continuous rotation of the rotating member, the alternating swinging of the main air guide vane and the secondary air guide vane is realized, so that the output air flow forms a wavy trajectory.

[0025] Compared with the traditional air outlet that swings left and right 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 directly blow towards the user, but blows towards the user in a sweeping manner, reducing the direct impact on the human body and enhancing the user experience.

[0026] As an improvement of the present invention, the first trajectory portion is a groove structure and is provided on the circumferential surface of the rotating member;

[0027] The first linkage member is a transmission pin extending into the first trajectory portion. The transmission pin moves left and right when traveling in the first trajectory portion, and the transmission pin drives the main air guiding blade to swing left and right through a transmission mechanism when moving left and right.

[0028] As an improvement of the present invention, the second trajectory portion is a groove structure and is provided on the axial end surface of the rotating member;

[0029] The rotating shaft of the secondary air guiding blade is arranged parallel to the axis A of the rotating member, and a coaxial crank is provided at one end of the rotating shaft of the secondary air guiding blade;

[0030] The second linkage member is a crank pin provided on the crank. The crank pin extends into the second trajectory portion.

[0031] As an improvement of the present invention, the transmission mechanism includes a moving member, a fork, and a transmission frame. The first linkage member is provided on the moving member, and the moving member is guided by a guiding structure provided on the air outlet housing to perform left and right translation;

[0032] The fork is provided on the moving member. The tail end of the transmission frame is rotatably connected to the air outlet housing, and the front end is in transmission connection with the fork. When the moving member performs left and right translation, the transmission frame is driven to rotate left and right through the fork;

[0033] The transmission frame is provided with two driving gears, and the central shafts of the main air guiding blades in the two air outlet channels are respectively provided with driven gears. The driven gears are independently meshed with the driving gears.

[0034] As an improvement of the present invention, the number of main air guiding blades in each air outlet channel is multiple and is arranged at intervals in the left and right directions of the air outlet channel. The multiple main air guiding blades are linked together through a connecting rod, and a driven gear is provided on the central shaft of one of the main air guiding blades.

[0035] As an improvement of the present invention, the first trajectory portion sequentially includes a variable diameter section a, a first intermittent section b, a variable diameter section c, a first intermittent section d, a variable diameter section e, a first intermittent section f, a variable diameter section g, and a first intermittent section h along the first direction;

[0036] Each reduced-diameter section is arranged in a leftward-changing trajectory along the first direction, and each first intermittent section is arranged in a structure without diameter change that is straight through from front to back;

[0037] In the initial position state, the first linkage member is at the leading end of the reduced-diameter section a, and drives the main air guiding vane to swing to a position where the air outlet passage is closed. The rotating member rotates along the second direction, and the main air guiding vane swings, and there is a position where the air outlet passage is opened.

[0038] As an improvement of the present invention, the second trajectory portion sequentially includes a second intermittent section aa, an adjustment section bb, a second intermittent section cc, an adjustment section dd, a second intermittent section ee, an adjustment section ff, a second intermittent section gg, and an adjustment section hh along the first direction;

[0039] In the initial position state, the second linkage member is located at the leading end of the second intermittent section aa, and drives the secondary air guiding vane to be in the reference position state. When the secondary air guiding vane is in the reference position state, the air intake amounts at the air intake ends of the two air outlet passages are the same. The rotating member rotates along the second direction, driving the secondary air guiding vane to swing upward or downward alternately.

[0040] As an improvement of the present invention, the air outlet housing is provided with two groups of air outlet passages that are symmetrically arranged left and right. Each of the two groups of air outlet passages is provided with a main air guiding vane, and a secondary air guiding vane is provided between the air intake ends of the two groups of air outlet passages;

[0041] The main air guiding vanes and the secondary air guiding vanes that cooperate with the two groups of air outlet passages are driven by independent rotating members;

[0042] The two rotating members are coaxially arranged, and the first trajectory portions of the two rotating members are arranged in a symmetric structure left and right, and the second trajectory portions of the two rotating members are arranged in a parallel structure.

[0043] As an improvement of the present invention, the main air guiding vanes of the two groups of air outlet passages swing symmetrically inward or outward to have a direct blowing air outlet state, a concentrated air outlet state, and a diffused air outlet state.

[0044] As an improvement of the present invention, the rotating member is arranged on the outside of the air outlet housing, and a mounting bracket is arranged on the outside of the air outlet housing for assembling an actuator. Description of the Drawings

Detailed implementation manners

[0057] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0058] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , and Figure 11 As shown, in Figure 2 , the air flow convergence path of the two air outlet channels 1.1 is represented by a red line, and in Figure 11 , the wavy air flow trajectory output by a single group of air outlet channels is represented by a red line.

[0059] A dual-channel air outlet, comprising:

[0060] The air outlet housing 1 is provided with two air outlet channels 1.1 separated up and down, and the airflows output by the two air outlet channels 1.1 intersect;

[0061] The secondary air guiding vane 2 is arranged between the air inlet ends of the two air outlet channels 1.1 in a vertically swingable manner. The vertical swing of the secondary air guiding vane 2 can control the opening degree of the air inlet ends of the air outlet channels 1.1, thereby controlling the air intake. When the air intakes of the two air outlet channels 1.1 are the same, the two airflows intersect and are output at a preset angle;

[0062] When the air intake of one of the air outlet channels 1.1 is less than that of the other air outlet channel 1.1, the two airflows intersect and tend to be output in the direction of the airflow output by the air outlet channel 1.1 with a larger air intake.

[0063] The main air guiding vane 3 is arranged in the air outlet channel 1.1 and can swing left and right, thereby adjusting the left and right air outlet angles;

[0064] 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;

[0065] The first track portion 5 has a variable diameter section and a first intermittent section arranged alternately. Among them, the variable diameter section is arranged along the axial variation path, and the first intermittent section is arranged without an axial variation path.

[0066] The second track portion 6 has an adjustment section and a second intermittent section arranged alternately. Among them, the adjustment section is arranged along the radial variation path, and the second intermittent section is arranged without a radial variation path. Adjacent adjustment sections are arranged with opposite radial variation trends;

[0067] The first linkage member 7 travels along the first track portion 5 and is linked with the main air guiding vane 3;

[0068] The second linkage member 8 travels along the second track portion 6 and is linked with the secondary air guiding vane 2;

[0069] When 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 variable diameter section. The second linkage member 8 drives the secondary air guiding vane 2 to be in an intermittent position where it stops swinging, and the first linkage member 7 drives the main air guiding vane 3 to swing left or right.

[0070] 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 air guiding vane 3 to be in an intermittent position where it stops swinging, and the second linkage member 8 drives the main air guiding vane 3 to swing up or down;

[0071] Through the continuous rotation of the rotating member 4, the alternating swinging of the main air guiding blade 3 and the secondary air guiding blade 2 is realized, so that the output air flow forms a wavy trajectory.

[0072] The first trajectory portion 5 provided on the rotating member 4 drives the main air guiding 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 trajectory portion 6 provided drives the secondary air guiding blade 2 to swing up and down through the second linkage member 8 to adjust the up and down air outlet angles.

[0073] After each angle adjustment of the main air guiding blade 3 is completed, it enters the intermittent position where it stops swinging. At this time, the rotating member 4 continues to rotate, which can drive the secondary air guiding blade 2 to swing upward and downward, and the air outlet direction can be adjusted up and down among multiple left and right air outlet angles.

[0074] Compared with the traditional air outlet that uses two actuators 4.1 to drive the main air guiding blade 3 and the secondary air guiding blade 2 to swing respectively to adjust the left and right wind directions and the up and down wind directions, this device only uses one actuator 4.1 to achieve the adjustment of the left and right wind directions and the up and down wind directions, and the cost is greatly reduced.

[0075] This device also has an air outlet mode with a wavy trajectory: through the continuous rotation of the rotating member 4, the alternating swinging of the main air guiding blade 3 and the secondary air guiding blade 2 is realized, so that the output air flow forms a wavy trajectory.

[0076] Compared with the traditional air outlet that outputs air flow swinging left and right 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 directly blow towards the user, but blows towards the user in a sweeping manner, reducing the direct impact on the human body and improving the use experience.

[0077] Please refer to Figure 3 、 Figure 4 、and Figure 5 as shown:

[0078] The first trajectory portion 5 is a groove structure and is provided on the circumferential surface of the rotating member 4;

[0079] The first linkage member 7 is a transmission pin extending into the first trajectory portion 5. The transmission pin moves left and right when traveling in the first trajectory portion 5, and the transmission pin drives the main air guiding blade 3 to swing left and right through the transmission mechanism when moving left and right.

[0080] Designing the first trajectory portion 5 as a groove structure and setting it on the circumferential surface of the rotating member 4 can perform axial variable diameter machining more directly and simply.

[0081] The second trajectory portion 6 is a groove structure and is provided on the axial end face of the rotating member 4;

[0082] The rotating shaft of the secondary air guiding vane 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 guiding vane 2;

[0083] The second linkage 8 is a crank pin arranged on the crank 2.1, and the crank pin extends into the second track portion 6.

[0084] The second track portion 6 is designed as a groove structure and arranged on the axial end face of the rotating member 4. It is distributed on different faces of the rotating member 4 from the first track portion 5, with a reasonable structural layout. It can perform radial diameter-changing processing more directly and simply.

[0085] As the crank pin travels along the second track portion 6, it drives the crank 2.1 to rotate, and then drives the secondary air guiding vane 2 to swing up and down. Compared with the traditional transmission structures using connecting rods or multi-stage gears, the present application has the characteristics of simple structure, fewer components, low cost, and stable and reliable operation.

[0086] In addition, the combination of the groove structure and the pin is tight, and it can accurately control the main air guiding vane and the secondary air guiding vane to swing according to the preset rules.

[0087] Please refer to Figure 4 、 Figure 5 as shown in:

[0088] The transmission mechanism includes a moving member 9, a fork 10, and a transmission frame 11. The first linkage 7 is arranged on the moving member 9. The moving member 9 is guided by a guiding structure arranged on the air outlet housing 1 to perform left and right translation. After the moving member 9 is connected to the first linkage 7, the first linkage 7 can also be guided and only perform left and right translation under the driving action of the first track portion 5;

[0089] The fork 10 is arranged on the moving member 9. The transmission frame 11 is located between two air outlet channels 1.1, and the tail end of the transmission frame 11 is rotatably connected to the air outlet housing 1, and the front end is in transmission connection with the fork 10. When the moving member 9 performs left and right translation, the transmission frame 11 is driven to perform left and right rotation through the fork 10;

[0090] Active gears 11.1 are respectively arranged at the upper end and the lower end of the transmission frame 11. Among them, the upper active gear 11.1 is meshed and connected with the driven gear 3.1 at the lower end of the central shaft of the main air guiding vane 3 in the upper air outlet channel 1.1, and the lower active gear 11.1 is meshed and connected with the driven gear 3.1 at the upper end of the central shaft of the main air guiding vane 3 in the lower air outlet channel 1.1.

[0091] For the above-mentioned transmission mechanism, the left and right translation of the first linkage 7 is sequentially converted into the left and right translation of the moving member 9, the left and right translation of the fork 10, and the left and right rotation of the transmission frame 11, and finally the left and right swing of the main air guiding vane 3 is realized through the gear transmission structure.

[0092] The separate control of the main air guide vanes 3 in the two air outlet channels 1.1 is realized, and the swing angle and speed of the main air guide vanes 3 can be accurately controlled. The structure is further optimized, the structure is simpler, and the cost is further reduced.

[0093] Please refer to Figure 2 、 Figure 3 、and Figure 5 as shown in:

[0094] There are multiple main air guide vanes 3 in each air outlet channel 1.1, and they are arranged at intervals in the left-right direction of the air outlet channel 1.1. The multiple main air guide vanes 3 are linked to each other through connecting rods. A driven gear 3.1 is arranged on the central axis of one of the main air guide vanes 3.

[0095] Multiple main air guide vanes 3 linked by connecting rods are respectively arranged in each air outlet channel 1.1, and a driven gear 3.1 is only arranged on the central axis of one of the main air guide vanes 3. The overall movement of the multiple main air guide vanes 3 is realized by the meshing of the driven gear 3.1 and the driving gear 11.1, further simplifying the structure and making the device more compact;

[0096] In addition, the multiple main air guide vanes 3 swing synchronously (with the same swing angle), resulting in the same air flow diversion effect and reducing the turbulence.

[0097] Please refer to Figure 4 、 Figures 6 - 9 as shown in:

[0098] The first track part 5 successively includes 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 along the first direction;

[0099] Each diameter-changing section is arranged in a trajectory that changes to the left along the first direction, and each first intermittent section is arranged in a structure without diameter change and is directly connected front and back;

[0100] In the initial position state, the first linkage 7 is at the head end of the diameter-changing section a and drives the main air guide vane 3 to swing to a position where the air outlet channel 1.1 is closed. The rotating member 4 rotates along the second direction, and the main air guide vane 3 swings forward and has a position where the air outlet channel 1.1 is opened.

[0101] After the above improvement, the head end of the diameter-changing section a is used as the starting point of the first track part 5. If the first linkage 7 is at the head end of the diameter-changing section a, the main air guide vane 3 at this time swings to a position where the air outlet channel 1.1 is closed in the swing direction (to the right) according to the closing of the air outlet channel 1.1;

[0102] Further, if the rotating member 4 rotates in the second direction, the first linkage member 7 travels along the diameter-changing section a, the first intermittent section b, the diameter-changing section c, the first intermittent section d, the diameter-changing section e, the first intermittent section f, the diameter-changing section g, and the first intermittent section h in sequence, and the main guide vane 3 swings in the swinging direction (to the left) for opening the air outlet passage 1.1. In the present application, the diameter-changing section a is utilized to drive the first linkage member 7 to have a position for closing the air outlet passage, so that the air outlet passage 1.1 can be closed, the air flow cannot be output, and external sundries are also prevented from entering the air outlet passage 1.1.

[0103] Please refer to Figure 4 、 Figures 6 - 11 as shown in:

[0104] The second track portion 6 includes, in sequence along the first direction, a second intermittent section aa, an adjustment section bb, a second intermittent section cc, an adjustment section dd, a second intermittent section ee, an adjustment section ff, a second intermittent section gg, and an adjustment section hh;

[0105] In the initial position state, the second linkage member 8 is located at the head end of the second intermittent section aa and drives the secondary guide vane 2 to be in the reference position state. When the secondary guide vane 2 is in the reference position state, the air intake amounts at the air intake ends of the two air outlet passages 1.1 are the same. The rotating member 4 rotates in the second direction, and the second linkage member 8 travels along the second intermittent section aa, the adjustment section bb, the second intermittent section cc, the adjustment section dd, the second intermittent section ee, the adjustment section ff, the second intermittent section gg, and the adjustment section hh in sequence, driving the secondary guide vane 2 to swing upward or downward alternately.

[0106] The second intermittent section aa has a matching stroke with the diameter-changing section a, the adjustment section bb has a matching stroke with the first intermittent section b, the second intermittent section cc has a matching stroke with the diameter-changing section c, the adjustment section dd has a matching stroke with the first intermittent section d, the second intermittent section ee has a matching stroke with the diameter-changing section e, the adjustment section ff has a matching stroke with the first intermittent section f, the second intermittent section gg has a matching stroke with the diameter-changing section g, and the adjustment section hh has a matching stroke with the diameter-changing section h.

[0107] In the present application, the continuous rotation of the rotating member 4 can be a reciprocating rotation along the first direction and the second direction, which can enable the first linkage member 7 to travel along a specific stroke section of the first track portion 5, and enable the second linkage member 8 to travel along a specific stroke section of the second track portion 6. The stroke section can be composed of multiple alternating diameter-changing sections and first intermittent sections, and multiple alternating adjustment sections and second intermittent sections, so as to cyclically output an air flow with a wavy track in a specific area.

[0108] Please refer to Figure 1 、 Figure 2 、and Figure 3 as shown in:

[0109] The air outlet housing 1 is provided with two groups of air outlet channels 1.1 that are symmetrically arranged left and right. Each of the two groups of air outlet channels 1.1 is provided with a main air guiding vane 3, and a secondary air guiding vane 2 is arranged between the air inlet ends of the two groups of air outlet channels 1.1;

[0110] The main air guiding vanes 3 and the secondary air guiding vanes 2 that cooperate with the two groups of air outlet channels 1.1 are driven by an independent rotating member 4;

[0111] 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 symmetric structure, and the second track portions 6 of the two rotating members 4 are arranged in a parallel structure.

[0112] Among them, for the rotating member 4 on the left side, along the first direction, its variable diameter section is arranged to have a decreasing diameter to the left. The swinging direction of the linked main air guiding vane 3 to close the air outlet channel 1.1 is to swing to the right, and the swinging direction to open the air outlet channel 1.1 is to swing to the left.

[0113] For the rotating member 4 on the right side, along the first direction, its variable diameter section is arranged to have a decreasing diameter to the right. The swinging direction of the linked main air guiding vane 3 to close the air outlet channel 1.1 is to swing to the left, and the swinging direction to open the air outlet channel 1.1 is to swing to the right.

[0114] The two rotating members 4 rotate synchronously.

[0115] The main air guiding vanes 3 of the two groups of air outlet channels 1.1 swing symmetrically inwards or outwards to have a direct blowing air outlet state, a concentrated air outlet state, and a diffused air outlet state.

[0116] After the above improvement, when the two groups of main air guiding vanes 3 swing to be inclined to the left and right sides, the device can expand the air outlet area for diffused air outlet;

[0117] When the two groups of main air guiding vanes 3 swing to be inclined to the middle position of the air outlet housing 1, the air can be concentrated to obtain a concentrated air outlet state;

[0118] When the two groups of main air guiding vanes 3 swing to be parallel to each other, the air can be directly blown out.

[0119] The rotating member 4 is arranged on the outside of the air outlet housing 1, and a mounting bracket is arranged on the outside of the air outlet housing 1 for assembling the actuator 4.1.

[0120] Arranging the rotating member 4 on the outside of the air outlet housing 1 and matching it with an outside mounting bracket to assemble the actuator 4.1 facilitates installation, debugging, and maintenance, and does not occupy the limited space inside the air outlet housing 1, which is beneficial to the optimized layout of the internal air duct structure and other components, and improves the rationality and compactness of the overall air outlet structure.

[0121] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
