Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a single-motor electric air outlet system and a vehicle. Background Art

[0002] The car air-conditioning vents are the terminals of the air-conditioning and ventilation system and are in direct contact with the passengers in the car. During the use of the air-conditioning, cold or hot air is blown out through the vents to adjust the temperature in the car to a suitable temperature. The air-conditioning vents can be adjusted to control the wind direction and size of the air.

[0003] Currently, controlling the airflow direction at the air outlet mainly relies on adjusting the angle of the fan blades. Dual motors are usually used to control the upper and lower blades and the left and right blades, respectively. However, dual motors are not only expensive, but also take up a lot of space, have a complex structure, and require a high maintenance rate.

[0004] However, the current control solution using a single motor can only control the swing of the upper and lower fan blades or the left and right fan blades separately at the same time, and cannot achieve synchronous swing of the upper and lower fan blades and the left and right fan blades at the same time, thereby providing three-dimensional air supply and improving the cooling effect. Summary of the Invention

[0005] In view of the defects existing in the prior art, the purpose of the present invention is to provide a single-motor electric air outlet system and vehicle to solve the problem in the prior art that it is impossible to use one drive motor to make the upper and lower fan blades and the left and right fan blades swing synchronously or separately.

[0009] Up and down swing wind components;

[0010] A driving member, the output end of which is connected to a first transmission mechanism for driving the left and right swing components and a second transmission mechanism for driving the up and down swing components. When the output end of the driving member rotates at a first interval angle, the first transmission mechanism drives the left and right swing components to rotate, and the second transmission mechanism drives the up and down swing components to rotate; when the output end of the driving member rotates at a second interval angle, the first transmission mechanism alone drives the left and right swing components to rotate; when the output end of the driving member rotates at a third interval angle, the second transmission mechanism alone drives the up and down swing components to rotate.

[0015] In some optional embodiments, a first return spring is provided on the first driven sector gear, for providing a rebound force for returning the first driven sector gear to the first set position after the first driven sector gear is disengaged from the first driving sector gear.

[0016] In some optional embodiments, the left and right swing wind assembly includes a plurality of vertical fan blades arranged at intervals, each of the vertical fan blades is rotatably connected to the first connecting rod, and any of the vertical fan blades is connected to the first driven sector gear.

[0017] In some optional embodiments, the second transmission mechanism includes:

[0018] A second driven sector gear connected to the up and down swing wind assembly;

[0019] A second active sector gear is connected to the output end of the driving member through the first transmission assembly, and the second active sector gear includes first sector teeth and second sector teeth that are circumferentially spaced apart;

[0020] When the output end of the driving member rotates at a first interval angle, the first sector teeth of the second driving sector gear are meshed with the second driven sector gear; when the output end of the driving member rotates at a second interval angle, the second driving sector gear is disengaged from the second driven sector gear; when the output end of the driving member rotates at a third interval angle, the second sector teeth of the second driving sector gear are meshed with the second driven sector gear.

[0021] In some optional embodiments, a second return spring is provided on the second driven sector gear for providing a rebound force for returning the second driven sector gear to the second set position after the second driven sector gear is disengaged from the second driving sector gear.

[0022] In some optional embodiments, the first transmission assembly includes:

[0023] a first bevel gear connected to the output end of the driving member;

[0024] The second bevel gear is vertically arranged and meshed with the first bevel gear, and the second driving sector gear is connected to the second bevel gear.

[0030] Compared with the prior art, the advantage of the present invention is that by rotating the driving member in the first interval angle, the second interval angle and the third interval angle, the first transmission mechanism and the second transmission mechanism are controlled, so that the left and right swing wind components and the up and down swing wind components work separately or simultaneously, and a motor can control the up and down wind direction and the left and right wind direction simultaneously or separately through different transmission mechanisms, which not only saves motors and reduces costs, but also reduces space occupancy and facilitates maintenance.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0040] On the one hand, if Figure 1 and Figure 2 As shown, the present application provides a single-motor electric air outlet system, comprising a left-right swing assembly 1, a vertical swing assembly 2, and a driver 5. By rotating the output end of the driver 5 at different interval angles, three swing modes can be controlled: Mode 1, controlling the left-right swing assembly 1 and the vertical swing assembly 2 to operate simultaneously; Mode 2, controlling the left-right swing assembly 1 alone; and Mode 3, controlling the vertical swing assembly 2 alone.

[0041] Specifically, the output end of the driving member 5 is connected to a first transmission mechanism 3 for driving the left and right swing assembly 1 and a second transmission mechanism 4 for driving the upper and lower swing assembly 2. When the output end of the driving member 5 rotates at a first interval angle, the first transmission mechanism 3 drives the left and right swing assembly 1 to rotate, and the second transmission mechanism 4 drives the upper and lower swing assembly 2 to rotate; when the output end of the driving member 5 rotates at a second interval angle, the first transmission mechanism 3 alone drives the left and right swing assembly 1 to rotate; when the output end of the driving member 5 rotates at a third interval angle, the second transmission mechanism 4 alone drives the upper and lower swing assembly 2 to rotate.

[0042] It can be understood that switching between the three swing modes is achieved by controlling the rotation interval angle of the output end of the driver 5. That is, when the output end of the driver 5 rotates at different interval angles, it is simultaneously connected to the first transmission mechanism 3 and the second transmission mechanism 4 or separately connected to each other, thereby driving the left and right swing assembly 1 and / or the vertical swing assembly 2 to rotate through the first transmission mechanism 3 and the second transmission mechanism 4.

[0043] Optionally, the driving member 5 is a stepping motor, so that the rotation angle of the output end of the driving member can be accurately controlled by a control mechanism.

[0044] In this example, the first transmission mechanism 3 includes a first driven sector gear 31 and a first active sector gear 32. The first driven sector gear 31 is connected to the left and right swing components 1. The sector curvature of the first active sector gear 32 is greater than the curvature of the first driven sector gear 31 and is connected to the output end of the driving member 5. The first active sector gear 32 includes a first driving section 321 and a second driving section 322.

[0045] When the output end of the driving member 5 rotates at a first interval angle, the first driving section 321 of the first driving sector gear 32 is meshed with the first driven sector gear 31; when the output end of the driving member 5 rotates at a second interval angle, the second driving section 322 of the first driving sector gear 32 is meshed with the first driven sector gear 31; when the output end of the driving member 5 rotates at a third interval angle, the first driving sector gear 32 is disengaged from the first driven sector gear 31.

[0046] It can be understood that both the first active sector gear 32 and the first driven sector gear 31 have latching teeth in the sector portion, while the latching teeth in other portions are missing. Moreover, the sector curvature of the first active sector gear 32 is greater than the curvature of the first driven sector gear, thereby enabling the first active sector gear 32 to mesh with the first driven sector gear 31 not only at the first interval angle, but also at the second interval angle after rotating past the first interval angle. This arrangement enables the control of the left and right swing wind assembly 1 in three modes to be achieved through the cooperation of the first active sector gear 32 and the first driven sector gear 31. It should be noted that when the output end of the driving member 5 rotates at the third interval angle, the positions of the missing latching teeth of the first active sector gear 32 and the first driven sector gear 31 correspond to each other, thereby no longer meshing, and the left and right swing wind assembly 1 stops working.

[0047] Preferably, the first driving interval 321 and the second driving interval 322 are adjacent to each other, and the interval angle of the first driving interval 321 is the same as the first interval angle, and the interval angle of the second driving interval 322 is the same as the second interval angle.

[0048] In order to enable the output end of the driving member 5 to rotate within the range of the first interval angle and the second interval angle to achieve full-angle swing control of the left and right swing assemblies 1, in some optional embodiments, when the first driven sector gear 31 is engaged with the first active sector gear 32 and rotates through the first driving interval 321, the first driven sector gear 31 is disengaged from the first active sector gear 32 and maintains the extreme rotation angle when disengaged, until the first active sector gear 32 rotates through the second driving interval 322 and begins to rotate in the opposite direction before disengagement, and then re-engages with the first active sector gear 32.

[0049] For example, the first driven sector gear 31 is connected to the output end of the first supporting mechanism. When the first driven sector gear 31 meshes with the first active sector gear 32 and rotates through the first driving interval 321, the first driven sector gear 31 maintains the limit rotation angle unchanged, and the output end of the first supporting mechanism pushes the first driven sector gear 31 out so that it no longer meshes with the first active sector gear 32 until the first active sector gear 32 rotates through the second driving interval 322. The output end of the first supporting mechanism retracts, so that the first active sector gear 32 meshes with the first driven sector gear 31 that maintains the above-mentioned limit rotation angle when it rotates through the limit position of the second driving interval 322 and rotates in the opposite direction, thereby reserving a rotation angle for the first active sector gear 32 and the second driven sector gear 41 to rotate in the opposite direction, so that the left and right swing wind assembly 1 can rotate at a full angle.

[0050] In this example, in order to further simplify the components and control process, a first return spring is provided on the first driven sector gear 31 to provide a rebound force for returning the first driven sector gear 31 to the first set position after being disengaged from the first driving sector gear 32 .

[0051] It is understood that the curvature of the first driven sector gear 31 is smaller than that of the first driving sector gear 32, and preferably, the curvature of the first driven sector gear 31 is smaller than or equal to the first driving section 321. When the first driven sector gear 31 meshes with the first driving sector gear 32 and rotates through the first driving section 321, the first driven sector gear 31 and the first driving sector gear 32 are disengaged, that is, the outermost teeth of the first driven sector gear 31 are no longer meshed with any tooth grooves of the first driving sector gear 32. The first driving sector gear 32 continues to rotate in this direction. Although the first return spring exerts a rebound force on the first driven sector gear 31 in the direction opposite to its original direction of rotation, the teeth on the second driving section 322 of the first driving sector gear 32 limit its rebound. This occurs until the first driving sector gear 32 rotates through the second driving section 322 to a point where the teeth on the first driving sector gear 32 are missing, at which point the first driven sector gear 31 disengages from the first driving sector gear 32. At this point, the outermost teeth on the first driven sector gear 31 are no longer restricted by the teeth on the first driving sector gear 32, and the first driven sector gear 31 rebounds by a set angle in the direction opposite to its original direction of rotation to a first set position. At this point, the tooth grooves of the first driven sector gear 31 correspond to the positions of the teeth on the first driving sector gear 32, allowing the first driving sector gear 32 to rotate in the opposite direction and re-engage with the first driven sector gear 31.

[0052] It should be noted that the number of engaging teeth within the first drive range 321 and the second drive range 322, as well as the number of engaging teeth on the first driven sector gear 31, can be specifically set based on the desired swing angles of the left-right swing assembly 1 and the up-down swing assembly 2. Based on the above technical solution, those skilled in the art can readily make appropriate adjustments based on actual needs. The transmission ratio between the first driven sector gear 31 and the first active sector gear 32 can also be set to allow the output end of the driver 5 to rotate a smaller angle, thereby controlling the left-right swing assembly 1 to swing within its left-right limit angles.

[0053] In this example, the first driven sector gear 31, under the action of the first return spring, rebounds in the direction opposite to its pre-disengagement rotation by a set angle corresponding to the central angle of the first driven sector gear 31's latching teeth. The position after rebound is the aforementioned first set position. The first set position is the position of the first driven sector gear 31 after rebounding in the direction opposite to its pre-disengagement rotation during the switching process from Mode 1 to Mode 2. At this first set position, the first driving sector gear 32 can re-engage with the first driven sector gear 31 by rotating in the direction opposite to its pre-disengagement rotation.

[0054] In some optional embodiments, the left-right swing assembly 1 includes a plurality of vertical blades 11 spaced apart from each other, each of which is rotatably connected to a first connecting rod 13, and each of which is connected to the first driven sector gear 31. When the first driven sector gear 31 swings clockwise or counterclockwise under the meshing action of the first driving sector gear 32, all of the vertical blades 11 are driven to swing left-right.

[0055] Specifically, in this example, multiple vertical blades 11 are rotatably connected horizontally at equal intervals within the first frame 12. All vertical blades 11 are connected to the first connecting rod 13, and the first driven sector gear 31 is fixedly connected to the rotation axis of any vertical blade 11. When the output end of the driving member 5 rotates left or right within the first or second angular interval, the first driven sector gear 31 drives all vertical blades 11 to swing within the left and right extreme angles.

[0056] In some optional embodiments, the second transmission mechanism 4 includes a second driven sector gear 41 and a second active sector gear 42, and the second driven sector gear 41 is connected to the up and down swing wind component 2; the second active sector gear 42 is connected to the output end of the driving member 5 through the first transmission component 43, and the second active sector gear 42 includes a first sector tooth 421 and a second sector tooth 422 arranged circumferentially at intervals.

[0057] When the output end of the driving member 5 rotates at a first interval angle, the first sector teeth 421 of the second driving sector gear 42 engage with the second driven sector gear 41; when the output end of the driving member 5 rotates at a second interval angle, the second driving sector gear 42 disengages from the second driven sector gear 41; when the output end of the driving member 5 rotates at a third interval angle, the second sector teeth 422 of the second driving sector gear 42 engage with the second driven sector gear 41.

[0058] It will be appreciated that the second active sector gear 42 includes first and second sector teeth 421, 422, spaced circumferentially apart to form two spaced meshing areas. This arrangement enables control of the vertical swing assembly 2 in three modes through the coordination of the second active sector gear 42 and the second driven sector gear 41. It should be noted that when the output end of the drive member 5 rotates within the second interval angle, the latching teeth of the second driven sector gear 41 correspond to the missing portion of the latching teeth between the first and second sector teeth 421, 422, and thus no longer mesh, causing the vertical swing assembly 2 to cease operation.

[0059] For example, when the output end of the driving member 5 rotates clockwise or counterclockwise at the first interval angle, the second driven sector gear 41 and the first sector tooth 421 are engaged, and the up and down swing wind assembly 2 can swing up and down; when the output end of the driving member 5 rotates clockwise or counterclockwise at the second interval angle, the second driven sector gear 41 does not engage with the first sector tooth 421 or the second sector tooth 422, but corresponds to the position of the missing part of the tooth between the first sector tooth 421 and the second sector tooth 422, and the up and down swing wind assembly 2 no longer swings up and down; when the output end of the driving member 5 rotates clockwise or counterclockwise at the third interval angle, the second driven sector gear 41 engages with the second sector tooth 422, and the up and down swing wind assembly 2 swings up and down again with the rotation of the output end of the driving member 5.

[0060] In this example, the first sector teeth 421 and the second sector teeth 422 are located at opposite ends of the radial direction. The central angle of the first sector teeth 421 is the same as the first interval angle, the central angle of the second sector teeth 422 is the same as the third interval angle, and the central angle of the portion of the missing teeth between the first sector teeth 421 and the second sector teeth 422 is the same as the second interval angle.

[0061] In order to enable the output end of the driving member 5 to rotate within the range of the first interval angle and the third interval angle, full-angle swing control of the upper and lower swing wind components 2 can be achieved, in some optional embodiments, when the second driven sector gear 41 and the first sector tooth 421 are engaged and rotated through the first interval angle, the second driven sector gear 41 disengages from the first sector tooth 421 and maintains the extreme rotation angle when disengaged, until the second active sector gear 42 rotates through the second interval angle and the third interval angle and rotates in the opposite direction before disengagement, and then re-engages with the second sector tooth 422 of the second active sector gear 42.

[0062] For example, the second driven sector gear 41 is connected to the output end of the second supporting mechanism. When the second driven sector gear 41 is meshed with the first sector gear 421 and rotates through the first interval angle, the second driven sector gear 41 maintains its limit rotation angle unchanged, and the output end of the second supporting mechanism pushes the second driven sector gear 41 out so that it no longer meshes with the second active sector gear 42, until the second active sector gear 42 rotates through the second interval angle and the third interval angle. The output end of the supporting mechanism retracts, so that the second sector gear 422 of the second active sector gear 42 is at the limit position after rotating through the third interval angle and starts to rotate in the opposite direction, and meshes with the second driven sector gear 41 that maintains the above-mentioned limit rotation angle, so that the up and down swing wind component 2 can rotate at full angles.

[0063] In this example, in order to further simplify the components and the control process, a second return spring is provided on the second driven sector gear 41 to provide a rebound force for the second driven sector gear 41 to return to the second set position after being disengaged from the second driving sector gear 42 .

[0064] It can be understood that when the second driven sector gear 41 meshes with the first sector teeth 421 of the second driving sector gear 42 and rotates through the first interval angle, the second driven sector gear 41 is disengaged from the first sector teeth 421 . The second driving sector gear 42 continues to rotate in this direction, and the missing part of the teeth between the first sector teeth 421 and the second sector teeth 422 corresponds to the tooth position of the second driven sector gear 41. Under the action of the second return spring, the second driven sector gear 41 rebounds by a set angle in the opposite direction of rotation before disengagement to the second set position, until the output end of the driving member 5 rotates through the second interval angle and rotates at the third interval angle. At this time, the outermost teeth of the second driven sector gear 41 are pushed by the teeth on the second sector teeth 422, and the second driven sector gear 41 is pushed back to its limit rotation angle, until the output end of the driving member 5 rotates through the third interval angle, all the teeth of the second sector teeth 422 rotate past the second driven sector gear 41, and the second sector teeth 422 no longer push the second driven sector gear 41 to limit the position. At this time, the second driven sector gear 41 is disengaged from the second sector teeth 422, and under the action of the second return spring, it rebounds again in the opposite direction to the setting angle before the disengagement to the second setting position, so that the tooth groove of the second driven sector gear 41 corresponds to the locking tooth position of the second sector teeth 422. The second driving sector gear 42 rotates in the opposite direction, and the second sector teeth 422 can be engaged with the second driven sector gear 41.

[0065] In this example, the second driven sector gear 41, under the action of the second return spring, rebounds in the direction opposite to its original rotation, at a predetermined angle corresponding to the central angle of the latching teeth of the second driven sector gear 41. This rebound position is the aforementioned second predetermined position, which is the position of the second driven sector gear 41 after rebounding in the direction opposite to its original rotation after disengaging from the second driving sector gear 42 during the transition from Mode 1 to Mode 2. At this second predetermined position, the second driving sector gear 42 can re-engage with the second driven sector gear 41 by rotating in the direction opposite to its original rotation.

[0066] It should be noted that the number of latching teeth within the first and second sector teeth 421, 422, as well as the number of latching teeth on the second driven sector gear 41, can be specifically set based on the desired swing angles of the left-right swing assembly 1 and the vertical swing assembly 2. Based on the above technical solution, those skilled in the art can readily make corresponding adjustments based on actual needs. Furthermore, the transmission ratio between the second driven sector gear 41 and the first and second sector teeth 421, 422 can be set so that the output end of the driver 5 rotates a smaller angle, thereby controlling the vertical swing assembly 2 to swing within the upper and lower limit angles.

[0067] In some optional embodiments, the above-mentioned first transmission mechanism 3 is specifically described. For example, when the output end of the driving member 5 rotates clockwise or counterclockwise within the range of the first interval angle, the first driven sector gear 31 and the first driving zone 321 of the first active sector gear 32 are engaged, and the left and right swing wind assembly 1 can be rotated from the left limit angle to the right limit angle, the second driven sector gear 41 is engaged with the first sector tooth 421 of the second active sector gear 42, and the upper and lower swing wind assembly 2 can be rotated from the upper limit angle to the lower limit angle; when the output end of the driving member 5 rotates through the range of the first interval angle and continues to rotate clockwise until it rotates to the second interval angle, at this time the first driven sector gear 31 and the second driving zone 322 of the first active sector gear 32 are engaged, and the left and right swing wind assembly 1 is at the left limit angle, the second interval angle is engaged. The second driven sector gear 41 is disengaged from the second active sector gear 42. When the output end of the driving member 5 rotates counterclockwise within the second interval angle, the left and right swing wind assembly 1 is in the right limit state, and the second driven sector gear 41 is disengaged from the second active sector gear 42; when the output end of the driving member 5 rotates past the second interval angle and continues to rotate clockwise, the first driven sector gear 31 is disengaged from the first active sector gear 32, and the second driven sector gear 41 is engaged with the second sector tooth 422 of the second active sector gear 42, and the upper and lower swing wind assembly 2 is at the upper limit angle. When the output end of the driving member 5 rotates counterclockwise, the upper and lower swing wind assembly 2 is at the lower limit angle, and the first driven sector gear 31 is disengaged from the first active sector gear 32.

[0068] It should be noted that no matter in which range angle the output end of the driving member 5 is located, when it is necessary to switch from one mode to another, it is only necessary to rotate the first driven sector gear 31 and the second driven sector gear 41 to the first set position and the second set position, and then rotate the output end of the driving member 5 in the opposite direction.

[0069] For example, when the first transmission mechanism 3 and the second transmission mechanism 4 are in Figure 4 When the output end of the driving member 5 is rotated counterclockwise, it can be switched to mode 1; when the first transmission mechanism 3 and the second transmission mechanism 4 are in Figure 5 When the output end of the driving member 5 is rotated counterclockwise, it can be switched to mode 2; when the first transmission mechanism 3 and the second transmission mechanism 4 are in Figure 8 , the output end of the driving member 5 is rotated counterclockwise to switch to mode three.

[0070] In some optional embodiments, the above-mentioned first transmission assembly 43 includes a first bevel gear 431 and a second bevel gear 432, and the first bevel gear 431 is connected to the output end of the above-mentioned driving member 5; the second bevel gear 432 is vertically arranged and meshed with the above-mentioned first bevel gear 431, and the above-mentioned second driving sector gear 42 is connected to the above-mentioned second bevel gear 432.

[0071] It can be understood that the purpose of providing the first bevel gear 431 and the second bevel gear 432 is to change the transmission direction of the output end of the driving member 5.

[0072] Since the movement directions of the fan blades of the upper and lower swing components 2 and the left and right swing components 1 are perpendicular to each other, in other embodiments, if the second active sector gear 42 is directly connected to the output end of the driving member 5, the first active sector gear 32 needs to change the transmission direction through the transmission component to achieve control of two groups of fan blades with different swing directions through one driving member 5.

[0073] In some optional embodiments, the second driven sector gear 41 is connected to the up and down swing wind assembly 2 through a second transmission assembly 44, and the second transmission assembly 44 includes a first transmission gear 441 and a second transmission gear 442, and the first transmission gear 441 is connected to the second driven sector gear 41; the second transmission gear 442 is connected to the first transmission gear 441 through a transmission chain 443.

[0074] In this example, the upper and lower swing air components 2 are located directly in front of the left and right swing air components 1, so that the upper and lower swing air components 2 and the left and right swing air components 1 can share an air-conditioning outlet, which not only reduces the number of air-conditioning outlets and reduces the space occupancy rate of the outlet system, but also when the left and right swing air components 1 and the upper and lower swing air components 2 work together, the wind direction can be made more uniform, thereby improving the comfort of the driver and passengers.

[0075] Therefore, the second driven sector gear 41 is connected to the upper and lower swing wind components through the second transmission component 44. Here, the distance between the upper and lower swing wind components 2 and the left and right swing wind components 1 can be adjusted by adjusting the length of the transmission chain 443.

[0076] Of course, in other embodiments, the left-right swing assembly 1 and the up-down swing assembly 2 can be located at different air outlets, or the left-right swing assembly 1 can be located right in front of the up-down swing assembly 2.

[0077] In some optional embodiments, the up and down swing wind assembly 2 includes a plurality of horizontal blades 21 arranged at intervals, each of the horizontal blades 21 is rotatably connected to the second connecting rod 23, and the second connecting rod 23 is connected to the second driven sector gear 41.

[0078] Specifically, in this example, multiple horizontal blades 21 are rotatably connected horizontally and evenly spaced within the second frame 22. All horizontal blades 21 are connected to the second connecting rod 23, and the second driven sector gear 41 is fixedly connected to the rotation axis of any horizontal blade 21. When the output end of the driving member 5 rotates left and right within the first or third angular intervals, the second driven sector gear 41 drives all horizontal blades 21 to swing within the upper and lower limit angles.

[0079] In some optional embodiments, the above system also includes a shell 6, the output end of the driving member 5 passes through the shell 6 and is rotatably connected to the shell 6, the first bevel gear 431 is located in the shell 6, and the rotating shaft of the second bevel gear 432 passes through the shell 6, and the above-mentioned first bevel gear 431 and the above-mentioned second bevel gear 432 engage and rotate in the above-mentioned shell 6.

[0080] The purpose of providing the housing 6 is to protect the first transmission assembly 43 and limit the meshing of the first bevel gear 431 and the second bevel gear 432 to prevent meshing failure and transmission failure.

[0081] In a second aspect, the present application also provides a vehicle comprising the above-mentioned single-motor electric air outlet system.

[0082] It can be understood that by arranging the above-mentioned electric air outlet system on the vehicle, the three swing modes of the left and right swing air component 1 and the up and down swing air component 2 can be controlled by controlling the rotation angle of the driving member 5.

[0083] The working principle of the embodiment of the present application is as follows: Figure 3 As shown, when the output end of the driving member 5 rotates within the first interval angle, the first driving interval 321 of the first active sector gear 32 is engaged with the above-mentioned first driven sector gear 31, and the above-mentioned second active sector gear 42 is engaged with the first sector tooth 421 of the second driven sector gear 41. At this time, when the driving member 5 rotates clockwise or counterclockwise within the first interval angle range, the vertical fan blades 11 rotate between the left limit angle and the right limit angle, and the horizontal fan blades 21 rotate between the upper limit angle and the lower limit angle, realizing the control of mode one, that is, the left and right swing components 1 and the up and down swing components 2 can swing at the same time.

[0084] like Figure 4 As shown, when the output end of the driving member 5 rotates through the first interval angle, the first driven sector gear 31 disengages from the first driving sector gear 32 and maintains the limit rotation angle when disengaging, and the second driven sector gear 41 disengages from the first sector gear 421, corresponding to the position of the missing part of the locking tooth between the first sector gear 421 and the second sector gear 422. Under the action of the second return spring, the second driven sector gear 41 rebounds in the opposite direction of rotation before disengagement by a circle center angle corresponding to the locking tooth. Figure 5 As shown, the first driving sector gear 32 continues to rotate clockwise until it passes the second driving interval 322. At this time, the first driven sector gear 31 is no longer supported by the first driving sector gear 32 and rebounds by a central angle corresponding to the tooth under the action of the first return spring. The first driving sector gear 32 rotates in the opposite direction and re-engages with the first driving sector gear 32. Figure 6 As shown, the output end of the driving member 5 can be controlled to rotate clockwise or counterclockwise within the second interval angle so that the vertical blades 11 rotate between the left limit angle and the right limit angle, while the horizontal blades 21 do not swing, thereby realizing the control of mode two, that is, the upper and lower swing components 2 do not swing, while the left and right swing components 1 swing.

[0085] like Figure 7 As shown, the output end of the driving member 5 continues to rotate clockwise through the second interval angle, at which time the first active sector gear 32 is disengaged from the first driven sector gear 31, and the first driven sector gear 31 rebounds by an angle corresponding to the center of the tooth under the action of the first return spring; Figure 8As shown, until the output end of the driving member 5 continues to rotate clockwise to the third interval angle, at which time the second driven sector gear 41 is pushed back to the limit angle by the second sector teeth 422 until the output end of the driving member 5 rotates past the third interval angle, and the second sector teeth 422 are disengaged from the second driven sector gear 41, and no longer push the second driven sector gear 41 to limit the position. At this time, the second driven sector gear 41 is disengaged from the second sector teeth 422, and under the action of the second return spring, it rebounds to the set angle in the opposite direction before the disengagement, so that the tooth groove of the second driven sector gear 41 corresponds to the locking tooth position of the second sector teeth 422. At this time, the second active sector gear 42 rotates counterclockwise, and the second sector teeth 422 are meshed with the second driven sector gear 41. As shown Figure 9 As shown, the output end of the driving member 5 can be controlled to rotate clockwise or counterclockwise within the third interval angle so that the horizontal blades 21 rotate between the upper limit angle and the lower limit angle, while the vertical blades 11 do not swing, thereby realizing the control of mode three, that is, the upper and lower swing components 2 swing, while the left and right swing components 1 do not swing.

[0086] The present invention provides a single-motor electric air outlet system and vehicle, which controls the left and right swing air components and the up and down swing air components differently by setting a driving member, thereby reducing the use of motors, reducing costs and facilitating maintenance; by setting the first transmission mechanism to the meshing of two sector gears, and the curvature of the first active sector gear is greater than the curvature of the first driven sector gear, and the first driven sector gear can be meshed in the first driving range and the second driving range, and disengaged from the first active sector gear at the position where the teeth are missing, thereby realizing three modes of control of the left and right swing air components; by setting a first return spring, the first driven sector gear can rebound to the set position after disengaging from the first active sector gear, so that when the first active sector gear rotates, it can re-engage with the first active sector gear; by setting the second transmission mechanism to two sector gears, and the second The active sector teeth include a first sector tooth and a second sector tooth which are arranged at circumferential intervals, so that three different modes of control can be realized when the second driven sector gear is respectively engaged with the first sector tooth and the second sector tooth and is located between the first sector tooth and the second sector tooth; by setting a second return spring, the second driven sector gear can rebound to the set position when it is located between the first sector tooth and the second sector tooth, so that it can re-engage with the first sector tooth and the second sector tooth; by setting a first bevel gear and a second bevel gear, the rotation direction of the output end of the driving member is changed; by sharing an air-conditioning outlet with the upper and lower swing air components and the left and right swing air components, not only the number of air-conditioning outlets can be reduced, the space occupancy rate of the outlet system can be reduced, but also when the left and right swing air components and the upper and lower swing air components work together, the wind direction can be made more uniform, thereby improving the comfort of the driver and passengers.
