Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, specifically relating to an air outlet structure, a control method for the air outlet structure, and an air conditioner. Background Technology

[0002] Air vents are devices used by air conditioners to regulate and control parameters such as temperature, humidity, and airflow of cool air entering an enclosed space. Roof-mounted integrated parking air conditioners are installed on the roof of passenger cars or trucks. For aesthetic reasons, the air vents are typically designed in a circular shape, and the direction of the airflow is manually controlled. Because the interior space is relatively small, manually adjusting the air vent direction requires standing up, which is inconvenient. Furthermore, once the air vent is fixed, its direction remains constant, causing the airflow to blow in one direction, which can easily cause discomfort to the user. A fixed airflow direction also slows down the diffusion of cool air inside the vehicle, hindering the rapid cooling of the interior.

[0003] like Figure 1 As shown, existing related technologies provide an air outlet structure, which includes a guide wheel 1', a sweeping blade 2', and two power units. The sweeping blade 2' has a rotating shaft and is rotatably mounted on the guide wheel 1' via the rotating shaft. One power unit 3' drives the guide wheel 1' to rotate, causing the guide wheel 1' to drive the sweeping blade 2' to rotate around the center line of the air outlet to guide the airflow. The other power unit 4' is also mounted on the guide wheel 1', and this other power unit 4' drives the sweeping blade 2' to rotate around the axis of the rotating shaft to sweep the airflow.

[0004] In the above technical solution, although the combination of two power units can achieve the effect of the sweeping blade 2' rotating to guide the air around the center line of the air outlet and to sweep the air around the axis of the rotating shaft, the number of two power units is too large, resulting in high cost. Summary of the Invention

[0005] Therefore, the present invention provides an air outlet structure, a control method for the air outlet structure, and an air conditioner. The main technical problem to be solved is: how to reduce the number of power units and reduce costs.

[0006] To address the aforementioned problems, the present invention provides an air outlet structure comprising a first power unit and a first sweeping blade; the first sweeping blade is disposed at the air outlet and has a rotating shaft; the axis of the rotating shaft is not parallel to the center line of the air outlet.

[0007] The first sweeping blade can be driven by a single first power device to move, so as to simultaneously rotate around the center line of the air outlet to guide the air and rotate around the axis of the rotating shaft to sweep the air.

[0008] In some embodiments, the axis of the rotating shaft is perpendicular to the centerline of the air outlet.

[0009] In some embodiments, the air outlet structure further includes a rotating component and a functional component; the first sweeping blade is fixed relative to the rotating shaft, and the first sweeping blade is rotatably mounted on the rotating component via the rotating shaft; the first power device drives the rotating component to drive the first sweeping blade and the rotating shaft to rotate around the center line of the air outlet, so that the first sweeping blade rotates to guide the air; a transmission structure is provided between the functional component and the rotating shaft; wherein, when the rotating shaft rotates around the center line of the air outlet, the functional component remains fixed, and the rotating shaft rotates around its own axis under the action of the transmission structure, so as to drive the first sweeping blade to rotate around the axis of the rotating shaft to sweep the air.

[0010] In some embodiments, a bevel gear is fitted on the rotating shaft, and the axis of the rotating shaft coincides with the center line of the bevel gear; the transmission structure includes transmission teeth fixed on the functional component, and the transmission teeth are arranged around the center line of the air outlet.

[0011] The transmission structure engages with a bevel gear via the transmission teeth, causing the bevel gear to rotate around the center line of the air outlet under the drive of the rotating shaft, and then rotate around its own center line under the action of the transmission teeth, thereby driving the rotating shaft to rotate around its own axis.

[0012] In some embodiments, the shaft is used to rotate alternately forward and reverse around its own axis under the drive of a bevel gear.

[0013] In some embodiments, the rotating shaft includes a first shaft portion located at one end of the first sweeping blade and a second shaft portion located at the other end of the first sweeping blade, and the bevel gear includes a first bevel gear and a second bevel gear, with the first bevel gear sleeved on the first shaft portion and the second bevel gear sleeved on the second shaft portion;

[0014] The transmission teeth are in multiple sets and are evenly spaced in a circle around the center line of the air outlet on the functional component; wherein, when the rotating shaft rotates around the center line of the air outlet, the first bevel gear and the second bevel gear alternately mesh with the transmission teeth, so that when the first bevel gear meshes with the transmission teeth, it drives the rotating shaft to rotate forward around its own axis, and when the second bevel gear meshes with the transmission teeth, it drives the rotating shaft to rotate in reverse around its own axis.

[0015] In some embodiments, the air outlet structure further includes a second power device; the second power device is used to drive the first sweeping blade to move, so that the first sweeping blade rotates around the axis of the rotating shaft to sweep air.

[0016] In some embodiments, the air outlet structure further includes a control device; the control device is used to control the first power unit and the second power unit to not operate simultaneously.

[0017] In some embodiments, when the air outlet structure includes a functional component, the air outlet structure further includes a first fixing structure, which is used to fix the functional component when the rotating shaft rotates around the center line of the air outlet, so that the functional component remains fixed; the first fixing structure is also used to release the functional component, so that the functional component can rotate around its own center line; wherein, the center line of the functional component coincides with the center line of the air outlet.

[0018] The air outlet structure also includes a second fixing structure, which is used to fix or unlock the first sweeping blade in the circumferential direction, so as to prevent the first sweeping blade from rotating around the center line of the air outlet when the first sweeping blade is fixed in the circumferential direction; and to enable the first power device to drive the first sweeping blade to rotate around the center line of the air outlet by driving the rotating component when the first sweeping blade is unlocked in the circumferential direction.

[0019] The second power unit is capable of fixing the first sweeping blade circumferentially with the second fixed structure, and driving the functional component to rotate around its own center line when the first fixed structure releases the functional component.

[0020] In some embodiments, the first fixing structure includes a first self-locking mechanism disposed on the second power device. The first fixing structure fixes the functional component by locking the second power device with the first self-locking mechanism, and releases the functional component by unlocking the second power device with the first self-locking mechanism.

[0021] And / or, the second fixing structure includes a second self-locking mechanism disposed on the first power device. The second fixing structure fixes the first sweeping blade circumferentially by locking the first power device with the second self-locking mechanism. The second fixing structure also unlocks the first sweeping blade circumferentially by unlocking the first power device with the second self-locking mechanism.

[0022] The present invention also provides a method for controlling an air outlet structure, which includes controlling the first power device and the second power device to not operate simultaneously.

[0023] The present invention also provides an air conditioner comprising the air outlet structure described in any one of the above-mentioned embodiments.

[0024] The air outlet structure, the control method for the air outlet structure, and the air conditioner provided by this invention have the following beneficial effects:

[0025] 1. Compared with the prior art, which requires two power devices to drive the first sweeping blade to rotate around the center line of the air outlet and to rotate around the axis of the rotating shaft for sweeping, the first sweeping blade in this invention can simultaneously rotate around the center line of the air outlet for guiding air and rotate around the axis of the rotating shaft because it is driven by a single power device (i.e., the first power device), thereby reducing the number of power devices and lowering costs.

[0026] 2. The functional component serves a dual purpose. When the second power unit is closed and the first power unit is activated, the functional component functions as a fixed component, allowing the first power unit to drive the sweeping blades to simultaneously rotate around the center line of the air outlet for air guidance and to rotate around the axis of the rotating shaft for air sweeping. When the first power unit is closed and the second power unit is activated, the functional component functions as a rotating component, allowing the second power unit to drive the sweeping blades to rotate around the axis of the rotating shaft for air sweeping.

[0027] 3. With the first and second power units, the driver does not need to manually adjust the air outlet direction. The air outlet can be electrically controlled to sweep and rotate. During use, the air outlet direction can be automatically adjusted back and forth to prevent the wind from blowing directly in one direction. Moreover, by automatically adjusting the air outlet position, the cold air can be quickly delivered to every corner to achieve a rapid cooling effect. The automatic adjustment of the air outlet position can also improve the driver's comfort. Attached Figure Description

[0045] See also Figures 2-6 As shown, according to an embodiment of the present invention, an air outlet structure is provided, which includes a first power unit 3 and a first sweeping blade 62. The first sweeping blade 62 is used to be disposed at the air outlet.

[0046] The first sweeping blade 62 has a rotating shaft 620. The axis of the rotating shaft 620 is not parallel to the center line of the air outlet. The first sweeping blade 62 can be driven by a single first power device 3 to move, so as to simultaneously rotate to guide air around the center line of the air outlet and to sweep air around the axis of the rotating shaft 620.

[0047] Compared to the prior art, which requires two power units to drive the first sweeping blade 62 to rotate around the center line of the air outlet and to rotate around the axis of the rotating shaft 620 for sweeping, the first sweeping blade 62 in this invention can simultaneously rotate around the center line of the air outlet and to rotate around the axis of the rotating shaft 620 for sweeping, driven by a single power unit (i.e., the first power unit 3). This reduces the number of power units and lowers costs.

[0048] In some embodiments, the axis of the aforementioned rotating shaft 620 is perpendicular to the center line of the air outlet, which helps the first sweeping blade 62 to guide the air to a larger area outside the air outlet.

[0049] To achieve the goal of simultaneously rotating the first sweeping blade 62 around the center line of the air outlet to guide airflow and rotating it around the axis of the rotating shaft 620 for sweeping, in some embodiments, such as... Figures 2 to 6 As shown, the aforementioned air outlet structure may further include a rotating component 71 and a functional component 42. The first sweeping blade 62 is fixed relative to the rotating shaft 620. The first sweeping blade 62 is rotatably mounted on the rotating component 71 via the rotating shaft 620. For example, the rotating component 71 may be provided with a first locking slot 7102, and the rotating shaft 620 on the first sweeping blade 62 is rotatably engaged in the first locking slot 7102, thereby allowing the first sweeping blade 62 to rotate relative to the rotating component 71 via the rotating shaft 620. The aforementioned first power device 3 drives the rotating component 71 to drive the first sweeping blade 62 and the rotating shaft 620 to rotate around the center line of the air outlet, causing the first sweeping blade 62 to rotate and guide the airflow.

[0050] A transmission structure is provided between the aforementioned functional component 42 and the rotating shaft 620. When the rotating shaft 620 rotates around the center line of the air outlet, the functional component 42 remains fixed, and the rotating shaft 620 rotates around its own axis under the action of the transmission structure, thereby driving the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 to sweep the air.

[0051] In the above example, the first power unit 3 can drive the first sweeping blade 62 and the rotating shaft 620 to rotate around the center line of the air outlet to guide the air. The functional component 42, the rotating shaft 620 and the transmission structure cooperate so that when the rotating shaft 620 rotates around the center line of the air outlet, it can rotate around its own axis under the action of the transmission structure. Since the first sweeping blade 62 is relatively fixed to the rotating shaft 620, the first sweeping blade 62 can also rotate around the axis of the rotating shaft 620 under the drive of the rotating shaft 620. Thus, the first sweeping blade 62 can be driven by a single first power unit 3 to move, so as to simultaneously rotate around the center line of the air outlet to guide the air and rotate around the axis of the rotating shaft 620 to sweep the air.

[0052] In order to enable the first power unit 3 to drive the rotating component 71 to drive the first sweeping blade 62 and the rotating shaft 620 to rotate around the center line of the air outlet, in some embodiments, such as Figure 2 and Figure 4 As shown, the centerline of the rotating component 71 coincides with the centerline of the air outlet. The rotating component 71 is a gear component. The first power device 3 includes a first drive motor and a first transmission gear 72. The first transmission gear 72 has a first gear mounting hole 721, and the first transmission gear 72 is fitted onto the output shaft of the first drive motor through the first gear mounting hole 721. The rotating component 71 can be a gear component, and the outer circumferential surface of the rotating component 71 has first transmission teeth 7101. The first transmission gear 72 is connected to the rotating component 71 in a transmission manner, for example, the two can mesh directly, or mesh through an intermediate gear. When the first drive motor starts, the first drive motor drives the rotating component 71 to rotate around its own centerline, i.e., the centerline of the air outlet, through the first transmission gear 72. The rotating component 71 drives the first sweeping blade 62 and the rotating shaft 620 on it to rotate together around the centerline of the air outlet.

[0053] To achieve the goal of allowing the aforementioned rotating shaft 620 to rotate around its own axis under the action of the transmission structure when rotating around the center line of the air outlet, in some embodiments, such as Figure 2As shown, a bevel gear 61 is fitted onto the aforementioned rotating shaft 620, and the axis of the rotating shaft 620 coincides with the center line of the bevel gear 61. The aforementioned transmission structure includes a transmission gear 4202 fixed on the functional component 42, and the transmission gear 4202 is arranged around the center line of the air outlet. The transmission structure engages with the bevel gear 61 through the transmission gear 4202, causing the bevel gear 61 to rotate around the center line of the air outlet under the drive of the rotating shaft 620, and then rotate around its own center line under the action of the transmission gear 4202, thereby driving the rotating shaft 620 to rotate around its own axis.

[0054] In the above example, the transmission gear 4202 is fixed, and the bevel gear 61 meshes with the transmission gear 4202. When the bevel gear 61 rotates around the center line of the air outlet with the rotating shaft 620, the bevel gear 61 rotates around its own center line under the action of the fixed transmission gear 4202. Since the bevel gear 61 and the rotating shaft 620 are fixedly set on the same axis, the bevel gear 61 will drive the rotating shaft 620 to rotate together, thereby achieving the purpose of the aforementioned rotating shaft 620 rotating around the center line of the air outlet and rotating around its own axis under the action of the transmission structure.

[0055] In some embodiments, the aforementioned rotating shaft 620 is used to alternately rotate forward and reverse around its own axis under the drive of the bevel gear 61. Since the first sweeping blade 62 and the rotating shaft 620 are fixed, the alternating forward and reverse rotation of the rotating shaft 620 can drive the first sweeping blade 62 to move back and forth, so that the first sweeping blade 62 can sweep air back and forth.

[0056] To achieve the goal of allowing the aforementioned rotating shaft 620 to alternately rotate clockwise and counterclockwise around its own axis under the drive of the bevel gear 61, in some embodiments, such as Figure 2 and Figure 5 As shown, the aforementioned rotating shaft 620 includes a first shaft portion 621 located at one end of the first sweeping blade 62 and a second shaft portion 622 located at the other end of the first sweeping blade 62. Both the first shaft portion 621 and the second shaft portion 622 are fixed to the first sweeping blade 62, and the axes of the first shaft portion 621 and the second shaft portion 622 coincide. The axis of either the first shaft portion 621 or the second shaft portion 622 is the axis of the rotating shaft 620. The aforementioned bevel gear 61 includes a first bevel gear 611 and a second bevel gear 612. The first bevel gear 611 is fitted onto the first shaft portion 621, and the second bevel gear 612 is fitted onto the second shaft portion 622.

[0057] The aforementioned transmission gears 4202 are in multiple sets and are evenly spaced in a circle around the center line of the air outlet on the functional component 42. When the rotating shaft 620 rotates around the center line of the air outlet, the first bevel gear 611 and the second bevel gear 612 alternately mesh with the transmission gears 4202, so that when the first bevel gear 611 meshes with the transmission gears 4202, it drives the rotating shaft 620 to rotate clockwise around its own axis, and when the second bevel gear 612 meshes with the transmission gears 4202, it drives the rotating shaft 620 to rotate counterclockwise around its own axis.

[0058] In the above example, there is a gap between two adjacent sets of transmission teeth 4202. When the first bevel gear 611 meshes with the transmission teeth 4202, the second bevel gear 612 is just located in the gap between the two sets of transmission teeth 4202. Similarly, when the second bevel gear 612 meshes with the transmission teeth 4202, the first bevel gear 611 is just located in the gap between the two sets of transmission teeth 4202. In this way, the first bevel gear 611 and the second bevel gear 612 can alternately mesh with the transmission teeth 4202 when the rotating shaft 620 rotates around the center line of the air outlet, thereby driving the rotating shaft 620 to rotate forward or backward around its own axis.

[0059] It should be noted that the aforementioned first bevel gear 611 and second bevel gear 612 can be symmetrically arranged on both sides of the first sweeping blade 62.

[0060] like Figure 5 As shown, the aforementioned air outlet structure also includes a second sweeping blade 63. The second sweeping blade 63 has another rotating shaft 6302, and the second sweeping blade 63 is rotatably mounted on the aforementioned rotating member 71 via this other rotating shaft 6302. Specifically, the aforementioned rotating member 71 may be provided with a second latch 7103, and the other rotating shaft 6302 on the second sweeping blade 63 is rotatably latched into the second latch 7103, thereby allowing the second sweeping blade 63 to rotate relative to the rotating member 71 via the other rotating shaft 6302.

[0061] The axis of the aforementioned rotating shaft 620 is parallel to and does not coincide with the axis of the other rotating shaft 6302. The first sweeping blade 62 can drive the second sweeping blade 63 to rotate and sweep air together via the connecting rod 64. There can be more than two second sweeping blades 63. In a specific application example, each sweeping blade is provided with a sweeping blade slot 6301, and the connecting rod 64 is provided with a connecting rod slot 6401. The number of connecting rod slots 6401 is equal to the number of sweeping blade slots 6301 and corresponds one-to-one. The connecting rod 64 engages with the corresponding sweeping blade slot 6301 through the corresponding connecting rod slot 6401.

[0062] In some embodiments, the air outlet structure of the present invention may further include a second power unit 2. The second power unit 2 is used to drive the first sweeping blade 62 to move, so that the first sweeping blade 62 rotates around the axis of the rotating shaft 620 to sweep air.

[0063] In the above example, the first power unit 3 and the second power unit 2 do not operate simultaneously. When the second power unit 2 is started alone, it can drive the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 to sweep air, without having to rotate around the center line of the air outlet at the same time, thus meeting different user needs according to actual conditions.

[0064] To save manpower, preferably, the air outlet structure of the present invention may include a control device, which is used to control the first power unit 3 and the second power unit 2 to not operate at the same time, so as to prevent interference when the first power unit 3 and the second power unit 2 are started at the same time.

[0065] It should be noted that the control device mentioned above can be a processor, etc. The control device is used to control the second power device 2 to close when the first power device 3 is started, and to control the first power device 3 to close when the second power device 2 is started, so as to achieve the purpose of controlling the first power device 3 and the second power device 2 to not operate at the same time.

[0066] To achieve the purpose of the aforementioned second power device 2 driving the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 for sweeping, as follows: Figures 2 to 6 As shown, in the example of the aforementioned air outlet structure including the functional component 42, the air outlet structure further includes a first fixing structure. This first fixing structure is used to fix the functional component 42 when the rotating shaft 620 rotates around the center line of the air outlet, keeping the functional component 42 fixed. Thus, when the rotating shaft 620 rotates around the center line of the air outlet, it can rotate around its own axis under the action of the transmission structure. The first fixing structure is also used to release the functional component 42, allowing the functional component 42 to rotate around its own center line. The center line of the functional component 42 coincides with the center line of the air outlet. The air outlet structure of the present invention also includes a second fixing structure, which is used to fix or unlock the first sweeping blade 62 circumferentially. When the second fixing structure fixes the first sweeping blade 62 circumferentially, it prevents the first sweeping blade 62 from rotating around the center line of the air outlet; and when the second fixing structure unlocks the first sweeping blade 62 circumferentially, it allows the first power device 3 to drive the first sweeping blade 62 to rotate around the center line of the air outlet via the driving rotating component 71.

[0067] The second power unit 2 can fix the first sweeping blade 62 circumferentially in the second fixed structure, and drive the functional component 42 to rotate around its own center line when the first fixed structure releases the functional component 42.

[0068] In the above example, when the second fixing structure fixes the first sweeping blade 62 circumferentially, the first sweeping blade 62 cannot rotate around the center line of the air outlet. At this time, the first sweeping blade 62 can only rotate around the axis of the rotating shaft 620 for sweeping. When the first fixing structure releases the functional component 42, the second power device 2 drives the functional component 42 to rotate around the axis of the rotating shaft 620. The functional component 42, through the transmission structure, drives the rotating shaft 620 to rotate around its own axis. Since the rotating shaft 620 is relatively fixed to the first sweeping blade 62, the rotating shaft 620 can drive the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 for sweeping. This achieves the purpose of the second power device 2 driving the first sweeping blade 62 to move, causing the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 for sweeping.

[0069] In addition, when the second fixed structure unlocks the first sweeping blade 62 circumferentially, the first power unit 3 can drive the first sweeping blade 62 and the rotating shaft 620 to rotate around the center line of the air outlet through the drive rotating component 71. At this time, the first fixed structure fixes the functional component 42. Thus, when the rotating shaft 620 rotates around the center line of the air outlet, it can rotate around its own axis under the action of the transmission structure. Since the rotating shaft 620 and the first sweeping blade 62 are relatively fixed, the rotating shaft 620 can drive the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 to sweep air. This achieves the purpose of the first power unit 3 driving the first sweeping blade 62 to move, so that the first sweeping blade 62 can simultaneously rotate around the center line of the air outlet to guide air and rotate around the axis of the rotating shaft 620 to sweep air.

[0070] It should be noted that the aforementioned functional component 42 serves two purposes. When the second power device 2 is closed and the first power device 3 is activated, the functional component 42 functions as a fixed component, allowing the first power device 3 to drive the sweeping blades to simultaneously rotate around the center line of the air outlet for air guidance and to rotate around the axis of the rotating shaft 620 for air sweeping. When the first power device 3 is closed and the second power device 2 is activated, the functional component 42 also functions as a rotating component 71, allowing the second power device 2 to drive the sweeping blades to rotate around the axis of the rotating shaft 620 for air sweeping by driving the functional component 42.

[0071] To achieve the function of the aforementioned first fixing structure, in some embodiments, the first fixing structure may include a first self-locking mechanism disposed on the second power device 2. The first fixing structure uses the first self-locking mechanism to lock the second power device 2, thereby fixing the functional component 42. The first fixing structure also uses the first self-locking mechanism to unlock the second power device 2, thereby releasing the functional component 42. In a specific application example, the second power device 2 may include a second drive motor and a second transmission gear 41. The second transmission gear 41 has a second gear mounting hole 4101 in the middle, and the second transmission gear 41 is fitted onto the output shaft of the second drive motor through the second gear mounting hole 4101. The functional component 42 may be a gear component, and the outer circumferential surface of the functional component 42 has a second transmission tooth 4201. The second transmission gear 41 is connected to the functional component 42 in a transmission manner, for example, the two may mesh directly or through an intermediate gear. When the second drive motor starts, the second drive motor drives the functional component 42 to rotate around its own center line, i.e., the center line of the air outlet, through the second transmission gear 41. The second drive motor can be a self-locking motor, and the first self-locking mechanism is the self-locking structure inside the self-locking motor. The specific structure of the first self-locking mechanism is existing technology and will not be described in detail here.

[0072] To achieve the function of the aforementioned second fixing structure, in some embodiments, the second fixing structure may include a second self-locking mechanism disposed on the first power device 3. The second fixing structure fixes the first sweeping blade 62 circumferentially by locking the first power device 3 through the second self-locking mechanism, and also unlocks the first sweeping blade 62 circumferentially by unlocking the first power device 3 through the second self-locking mechanism. In the example where the first power device 3 includes a first drive motor, the first drive motor can be a self-locking motor, and the second self-locking mechanism is a self-locking structure within the self-locking motor. The specific structure of the second self-locking mechanism is prior art and will not be described in detail here.

[0073] In some implementations, such as Figure 2 As shown, the number of air outlets can be two or more. The number of rotating parts 71 is equal to the number of air outlets and corresponds one-to-one. Adjacent rotating parts 71 are connected by a second connecting gear 73, enabling the first power device 3 to drive all rotating parts 71 to rotate simultaneously. The number of first sweeping blades 62 is equal to the number of rotating parts 71 and corresponds one-to-one. The number of functional parts 42 is equal to the number of first sweeping blades 62 and corresponds one-to-one. Adjacent functional parts 42 are connected by a first connecting gear 43, enabling the second power device 2 to drive all functional parts 42 to rotate simultaneously.

[0074] It should be noted that the aforementioned rotating parts 71 and the second connecting gear 73 cooperate to form the first transmission structure 7, and the aforementioned functional parts 42 cooperate with the first connecting gear 43 to form the second transmission structure 4.

[0075] like Figure 1 As shown, the air outlet structure of the present invention also includes an air outlet panel 1 connected to the evaporator chamber of the air conditioner body. The aforementioned first and second drive motors are both self-locking motors, and both are mounted and fixed to designated positions on the air outlet panel 1. The first and second drive motors cannot be started simultaneously. The air outlet structure also includes a gear limiting member 5, which limits the first connecting gear 43 between two adjacent functional components 42, preventing the first connecting gear 43 from moving upwards and disengaging from gear engagement. The gear limiting member 5 also positions the second connecting gear 73 between two adjacent rotating components 71, fixing the second connecting gear 73 in a suitable position. The air outlet structure also includes a gear limiting cover plate 8, which limits each rotating component 71 and the second connecting gear 73, preventing each rotating component 71 and the second connecting gear 73 from moving upwards and disengaging from the designated position.

[0076] The present invention also provides a method for controlling an air outlet structure, which includes controlling the first power unit 3 and the second power unit 2 to not operate simultaneously.

[0077] In the above example, the first power unit 3 and the second power unit 2 do not operate simultaneously. When the second power unit 2 is started alone, it can drive the first sweeping blade 62 to rotate around the axis of the rotating shaft 620 to sweep air, without having to rotate around the center line of the air outlet at the same time, thus meeting different user needs according to actual conditions.

[0078] The working principle and control process of this invention are as follows:

[0079] like Figure 7As shown, when the second power unit 2 is started and the first power unit 3 is turned off, the second transmission structure 4 moves while the first transmission structure 7 remains stationary (when the first power unit 3 is powered on but not started, it can automatically lock itself, and the motor shaft of the first power unit 3 cannot rotate under force). The functional component 42 rotates, driving the transmission gear 4202 on it to rotate together. When the transmission gear 4202 on the functional component 42 meshes with the first bevel gear 611 on the first sweeping blade 62, the second bevel gear 612 on the first sweeping blade 62 is in a missing tooth position, and the sweeping blade will sweep to the left. When the transmission gear 4202 on the functional component 42 meshes with the second bevel gear 612 on the first sweeping blade 62, the first bevel gear 611 is in a missing tooth position, and the sweeping blade will sweep to the right. The functional component 42 drives the transmission gear 4202 to rotate continuously, causing the first bevel gear 611 and the second bevel gear 612 to alternately mesh with the transmission gear 4202, thereby causing the first sweeping blade 62 to sweep back and forth left and right.

[0080] When the first power unit 3 is started and the second power unit 2 is turned off, the first transmission structure 7 moves and the second transmission structure 4 remains stationary (when the second power unit 2 is powered on but not started, it can automatically lock itself, and the motor shaft of the second power unit 2 cannot rotate under force). The rotating part 71 rotates, driving the first sweeping blade 62 to rotate. The bevel gear 61 will mesh with the stationary transmission gear 4202 to drive the transmission. In this way, while the first sweeping blade 62 rotates around the center line of the air outlet, the sweeping blade also rotates around the axis of the rotating shaft 620, thereby achieving both rotation and sweeping.

[0081] The present invention also provides an air conditioner that may include the air outlet structure described above. Because the air conditioner employs the aforementioned air outlet structure, compared to the prior art which requires two power units to drive the first sweeping blade 62 to rotate around the center line of the air outlet and to rotate around the axis of the rotating shaft 620 for air sweeping, the first sweeping blade 62 in the present invention can simultaneously rotate around the center line of the air outlet and rotate around the axis of the rotating shaft 620, driven by a single power unit (i.e., the first power unit 3). This reduces the number of power units and lowers costs.

[0082] In a specific application example, the air conditioner mentioned above can be a parking air conditioner.

[0083] The first power unit 3 and the second power unit 2 enable the driver to control the sweeping and rotation of the air outlets electrically without having to manually adjust the air outlet direction. During use, the air outlet direction can be automatically adjusted back and forth to prevent the wind from blowing directly in one direction. Moreover, by automatically adjusting the air outlet position, the cold air can be quickly delivered to every corner to achieve a rapid cooling effect. The automatic adjustment of the air outlet position can also improve the driver's comfort.

[0084] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0085] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
