Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a single-motor controlled air outlet structure assembly. Background Technology

[0002] Air conditioning vents are installed inside vehicles to blow out hot or cold air, which then enters the vehicle interior to regulate the temperature.

[0003] For example, Chinese patent number CN201520659075.0, patent title: An electric air conditioning vent for automobiles, including an air outlet channel and an air outlet panel. Several transverse air outlet blades are rotatably arranged on the air outlet channel. Each transverse air outlet blade is provided with a first extension rod, and each first extension rod is rotatably connected to a first connecting rod. A first stepper motor is provided on one side of the air outlet channel. The output shaft of the first stepper motor is connected to a first gear. At least one of the transverse air outlet blades is provided with a second gear that cooperates with the first gear. This structure realizes the opening and closing and direction adjustment of the transverse air outlet blades through the first stepper motor, and realizes the opening and closing and direction adjustment of the longitudinal air outlet blades through the second stepper motor. At the same time, two motors are used to complete different functions.

[0004] Therefore, existing ventilation systems typically require multiple motors to control the air guide vanes and exhaust blades (or two sets of exhaust blades, one above the other) to adjust the direction and magnitude of airflow. This design not only increases manufacturing costs but also enlarges the product, hindering the trend towards miniaturization and integration. Furthermore, multi-motor solutions also lead to low energy efficiency and poor reliability. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a single motor controlled air outlet structure assembly.

[0006] The technical solution adopted by this utility model to solve its technical problem is to propose a single motor controlled air outlet structure assembly, including an air outlet shell and an air guide plate and several sets of air outlet blades disposed therein, a first transmission component and a second transmission component movably disposed therein, the first transmission component being movably connected to the air guide plate and driving it to swing; the second transmission component being movably connected to the air outlet blades and driving them to swing within the air outlet shell.

[0007] The drive unit has a forward rotation state and a reverse rotation state. When the drive unit is in the forward rotation state, the output end of the drive unit is movably connected to the first transmission component to drive the air guide plate to swing back and forth in the air outlet housing. When the drive unit switches to the reverse rotation state, the output end of the drive unit is disengaged from the first transmission component and movably connected to the second transmission component to control several sets of air outlet blades to swing back and forth relative to the air outlet housing.

[0008] In the above-mentioned single-motor controlled air outlet assembly, the driving component includes:

[0009] A drive motor, wherein a drive crank is coaxially connected to the drive end of the drive motor;

[0010] Both the drive disc and the elastic element are coaxially arranged with the drive crank, and the drive disc is movably pressed against the drive crank; the two ends of the elastic element are respectively connected to the drive disc and the first transmission assembly.

[0011] When the drive motor drives the drive crank to rotate forward, the drive disc can squeeze the elastic element, causing the drive disc to move against the first transmission component, thereby driving the air guide plate to swing; and when the drive motor rotates in reverse, the elastic element will push the drive disc to disengage from the first transmission component and move against the second transmission component, thereby driving the air outlet blades to swing.

[0012] In the above-mentioned single-motor controlled air outlet structure assembly, a buffer pad is also installed on the drive disk. The buffer pad is used to prevent noise generated when the drive disk switches between forward and reverse rotation states with the drive motor.

[0013] In the above-mentioned single-motor controlled air outlet structure assembly, a number of drive blocks are evenly distributed on the drive crank, and a number of switching slots are evenly opened in a ring at the end of the drive disk. The drive blocks extend into the switching slots and can reciprocate between the first position and the second position of the switching slot.

[0014] When the drive block is in the first position of the switching slot, the drive disk is movably connected to the first transmission component to realize the swing of the air guide plate in the air outlet housing.

[0015] When the drive block switches from the first position to the second position, the drive disk can be movably connected to the second transmission component due to the elastic reset of the elastic element, and is used to drive the air outlet blades to swing back and forth relative to the air outlet housing.

[0016] In the above-mentioned single-motor controlled air outlet structure assembly, each of the switching slots includes an L-shaped slot and a mating surface opened along the axis of the drive disc, and the L-shaped slot and the mating surface are connected by a guide slope.

[0017] In the above-mentioned single-motor controlled air outlet structure assembly, the depth of the L-shaped groove along the axis of the drive disk is greater than the depth of the mating surface along the axis of the drive disk.

[0018] In the above-mentioned single-motor controlled air outlet structure assembly, the first transmission component includes:

[0019] The transmission disc has an assembly housing installed on the side wall of the air outlet housing. The transmission disc is movably disposed in the assembly housing. A traction groove is formed on one side of the transmission disc, and a first connecting part is formed on the other side. A first engaging part is formed on the drive disc, and the first engaging part is movably connected to the first connecting part.

[0020] The first connecting rod is connected to the rotating shaft of the air guide plate. A guide post is formed at the end of the first connecting rod. An arc-shaped limiting groove is formed on the side wall of the assembly housing. The guide post passes through the arc-shaped limiting groove and is movably engaged in the traction groove.

[0021] In the above-mentioned single-motor controlled air outlet assembly, the second transmission component includes:

[0022] A track disk is movably disposed within the assembly housing. An arc-shaped guide groove is formed on the outer wall of the track disk, and a second connecting portion is formed on the inner wall of the track disk. A second engaging portion is formed on the side of the drive disk opposite to the first engaging portion, and the second engaging portion is movably connected to the second connecting portion.

[0023] The second link is movably connected to several sets of air outlet blades. A traction column is formed at the end of the second link. A guide groove is formed on the outer wall of the assembly housing along its axial direction. The traction column passes through the guide groove and is movably engaged in the arc-shaped guide groove.

[0024] In the above-mentioned single-motor controlled air outlet structure assembly, the first connecting part, the second connecting part, the first engaging part, and the second engaging part are all composed of a number of interconnected protruding teeth arranged in a circular array.

[0025] The technical solution adopted by this utility model to solve its technical problem is to propose a single motor controlled air outlet structure assembly, including an air outlet shell and an air guide plate and several sets of air outlet blades disposed therein.

[0026] The device includes a first transmission component and a second transmission component. The first transmission component is movably connected to the air guide plate and drives it to swing. The second transmission component is movably connected to the air outlet blade and drives it to swing within the air outlet housing.

[0027] The drive unit has a forward rotation state and a reverse rotation state. When the drive unit is in the forward rotation state, the output end of the drive unit is movably connected to the second transmission component to drive several sets of air outlet blades to reciprocate within the air outlet housing. When the drive unit switches to the reverse rotation state, the output end of the drive unit disengages from the second transmission component and is movably connected to the first transmission component to control the air guide plate to reciprocate relative to the air outlet housing.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The single motor control air outlet structure assembly of this utility model uses a single drive motor to selectively connect the first transmission component and the second transmission component by switching between forward and reverse rotation, thereby alternately controlling the swing of the air guide plate and the air outlet blade. The overall structure is relatively compact, which helps to save installation space and enhance the user experience. At the same time, without adding an extra motor, it realizes dual control of the direction and size of the air outlet, making the operation more intuitive and convenient.

[0030] (2) By setting a buffer pad on the drive disk, noise generated when the drive motor switches between forward and reverse states is effectively prevented from being generated when the drive disk and the track disk are in motion.

[0031] (3) The depth of the L-shaped groove along the axis of the drive disk is greater than the depth of the mating surface along the axis of the drive disk. This design, combined with the elastic deformation of the elastic element, ensures that the drive disk can be stably connected to the transmission disk or track disk when switching between forward and reverse states of the drive motor, thereby improving the smoothness and stability of the single motor controlling the air guide plate and the air outlet blades to swing.

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly. Example

[0043] like Figures 1 to 4As shown, this utility model discloses a single-motor controlled air outlet structure assembly, including an air outlet housing 1, an air guide plate 10 disposed therein, and several sets of air outlet blades 11; a first transmission assembly 2 and a second transmission assembly 3 movably disposed therein, the first transmission assembly 2 being movably connected to the air guide plate 10 and driving it to swing; the second transmission assembly 3 being movably connected to the air outlet blades 11 and driving them to swing within the air outlet housing 1; a drive member 4 having a forward rotation state and a reverse rotation state, when the drive member 4 is in the forward rotation state, the output end of the drive member 4 is movably connected to the first transmission assembly 2, used to drive the air guide plate 10 to swing back and forth within the air outlet housing 1; when the drive member 4 switches to the reverse rotation state, the output end of the drive member 4 disengages from the first transmission assembly 2 and is movably connected to the second transmission assembly 3, used to control the several sets of air outlet blades 11 to swing back and forth relative to the air outlet housing 1.

[0044] This solution primarily aims to achieve alternating control of the oscillation of the air guide plate 10 and the air outlet blades 11 by a single motor. Specifically, as shown... Figures 1 to 4 As shown, the air guide plate 10 is located at the air inlet of the air outlet housing 1, and several sets of air outlet blades 11 are distributed at the air outlet of the air outlet housing 1. When the user selects to adjust the airflow direction at the air inlet, the control system issues a command to make the drive component 4 enter the forward rotation state (e.g., Figure 1 As shown in the state, the output end of the drive component 4 can be movably connected to the first transmission component 2 through mechanical connection or electromagnetic coupling. Since one end of the first transmission component 2 is connected to the output end of the drive component 4 and the other end is movably connected to the air guide plate 10, the first transmission component 2 can convert the rotational motion into linear or angular oscillation, thereby driving the air guide plate 10 to oscillate back and forth in the air outlet housing 1, changing the direction of the airflow. Similarly, when the user wants to adjust the width or range of the airflow, the control system can switch the drive component 4 to the reverse state. At this time, the output end of the drive component 4 is disengaged from the first transmission component 2 and movably connected to the second transmission component 3. As the second transmission component 3 receives the power from the drive component 4 and transmits it to the air outlet blade 11, the air outlet blade 11 can oscillate back and forth relative to the air outlet housing 1, thereby adjusting the direction and size of the airflow. As can be seen, this structure uses a single drive unit 4 instead of multiple motors, which greatly reduces the number of parts and lowers the assembly difficulty and cost. Moreover, this solution saves the installation space of the entire air outlet structure, allowing for a more compact product design. This not only helps to reduce the overall size, but also makes the equipment more adaptable to various installation environments, bringing great convenience to users.

[0045] The driving component 4 includes: a driving motor 40, with a driving crank 41 coaxially connected to the driving end of the driving motor 40; a driving disk 42 and an elastic element 43, both coaxially arranged with the driving crank 41, with the driving disk 42 movably pressing against the driving crank 41; the two ends of the elastic element 43 are respectively connected to the driving disk 42 and the first transmission assembly 2; when the driving motor 40 drives the driving crank 41 to rotate forward, the driving disk 42 can squeeze the elastic element 43, causing the driving disk 42 to movably press against the first transmission assembly 2, thereby driving the air guide plate 10 to swing; and when the driving motor 40 rotates in reverse, the elastic reset of the elastic element 43 pushes the driving disk 42 to disengage from the first transmission assembly 2 and movably press against the second transmission assembly 3, thereby driving the air outlet blade 11 to swing.

[0046] like Figures 1 to 4 As shown, in this embodiment, an elastic element 43 is provided between the end of the first transmission assembly 2 away from the air guide plate 10 and the drive disk 42. When the drive motor 40 (in this embodiment, other drive devices such as stepper motors and servo motors can be used instead) switches from the reverse state to the forward state, the drive crank 41 can be... Figure 1 The position shown is in a clockwise direction (i.e.) Figure 1 Rotate to (in the direction indicated by the arrow) Figure 3 As shown, during this process, the drive disc 42 is subjected to axial compressive force from the drive crank 41, which causes the elastic element 43 to connect the drive disc 42 to the first transmission assembly 2 under compression. Figure 3 The drive crank 41, in the state shown, continues to rotate (along...) Figure 1 During the process (in the direction indicated by the arrow), the rotational motion of the drive disc 42 can be converted into the force that drives the guide plate 10 to swing back and forth, which is the first transmission component 2; and when the drive motor 40 switches to the reverse state, it can drive the drive crank 41 along the direction indicated by the arrow. Figure 3 Rotating in the direction of the arrow, the drive disc 42 is no longer subjected to the squeezing force of the drive crank 41. Under the elastic restoring action of the elastic element 43, it is pushed... Figure 2 As the drive disc 42 moves to the right, it is movably connected to the second transmission assembly 3. With the continuous rotation of the drive crank 41, the rotational motion of the drive disc 42 is converted into a force that drives several sets of air outlet blades 11 to reciprocate. This structure introduces a combined design of the drive crank 41, drive disc 42, and elastic element 43, reducing additional switching mechanisms or complex electronic control systems, thus lowering the overall complexity and manufacturing cost. At the same time, the design of the elastic element 43 not only provides a reliable switching function but also acts as a buffer, reducing the impact of impact loads on the transmission assembly and improving the reliability and durability of the entire system.

[0047] Preferably, the elastic element 43 in this embodiment can be replaced by other elastic devices such as compression springs or return springs.

[0048] A plurality of drive blocks 410 are equidistantly distributed on the drive crank 41. A plurality of switching slots 421 are equidistantly opened in a ring at the end of the drive disc 42. The drive blocks 410 extend into the switching slots 421 and can reciprocate between the first position and the second position of the switching slots 421. When the drive block 410 is in the first position of the switching slot 421, the drive disc 42 is movably connected to the first transmission component 2 to realize the swing of the air guide plate 10 in the air outlet housing 1. When the drive block 410 switches from the first position to the second position, the drive disc 42 can be movably connected to the second transmission component 3 due to the elastic reset of the elastic element 43 to drive the air outlet blade 11 to swing back and forth relative to the air outlet housing 1.

[0049] In this embodiment, each drive block 410 corresponds to a switching slot 421, and the drive block 410 can switch between a first position and a second position within the switching slot 421. The equidistant distribution of the switching slots 421 provides a uniform switching timing, avoiding functional failure due to positional deviations. Specifically, as... Figure 1 and Figure 3 As shown, in the driving block 410 by Figure 1 When the first position of the switching slot 421 shown rotates in the direction of the arrow, the drive block 410 will inevitably apply a certain squeezing force to the drive disk 42. As the drive disk 42 moves along... Figure 2 As the drive disc 42 moves to the left towards the first transmission assembly 2, the elastic element 43 is gradually compressed, ultimately achieving connection between the drive disc 42 and the first transmission assembly 2. It is worth noting that at this moment, the drive block 410 also rotates to... Figure 3 The second position of the switching slot 421 is shown, where the drive block 410 no longer applies the drive disk 42 along the second position. Figure 2 The force that moves to the left, along with the drive crank 41 driving the drive block 410 along... Figure 3 When rotated in the opposite direction of the arrow, the drive crank 41, drive disc 42, and the first transmission assembly 2 connected to them can rotate synchronously to realize the oscillation of the air guide plate 10. Therefore, with the cooperation of the elastic element 43 and the switching groove 421, the accuracy and reliability of the drive disc 42 switching between different transmission assemblies are ensured. Conversely, when the drive block 410 is rotated by... Figure 3 When the drive block 410 rotates in the direction of the arrow at the indicated position, it no longer applies pressure to the drive disk 42. Instead, relying on the elastic restoring force of the elastic element 43, it pushes the drive disk 42 along... Figure 2 Move to the right, until the drive block 410 is in Figure 1 When the switching slot 421 is in the first position, the drive disk 42 and the second transmission component 3 are also connected. Finally, the reciprocating swing of the air outlet blade 11 can be achieved when the drive motor 40 continues to reverse.

[0050] Each switching slot 421 includes an L-shaped slot 421a and a mating surface 421b opened along the axis of the drive disk 42. The L-shaped slot 421a and the mating surface 421b are connected by a guide slope 421c.

[0051] Furthermore, such as Figure 2 As shown, each switching slot 421 in this embodiment is formed by an L-shaped slot 421a and a mating surface 421b, as... Figure 1 As shown, when the drive block 410 falls into the L-shaped groove 421a (i.e., the first position of the aforementioned switching groove 421), as the drive crank 41 moves along... Figure 1 When rotated in the direction indicated by the arrow, the drive block 410 can push the drive disk 42 along... Figure 2 Move to the left and connect to the first transmission assembly 2 until the drive block 410 abuts against the abutment surface 421b (as shown). Figure 3 In the state shown (i.e., the second position of the switching slot 421), the elastic element 43 no longer compresses and deforms. Relying on the abutment between the drive block 410 and the abutment surface 421b, the first transmission component 2 can be driven to rotate and converted into the reciprocating oscillation of the air guide plate 10. In the above process, the guide slope 421c formed between the two provides a clear path for the drive block 410, ensuring the stability of the drive block 410 during the transition to the oscillation of the air guide plate 10, avoiding functional failure due to positional deviation. At the same time, the design of the L-shaped slot 421a and the abutment surface 421b ensures the accuracy of the drive block 410 when it is in the first and second positions of the switching slot 421, increasing the efficiency and stability of power transmission, and providing a guarantee for the smoothness and stability of the reciprocating oscillation of the air guide plate 10 and the air outlet blade 11. It should be noted that when the drive block 410 is... Figure 3 When the second position of the switching slot 421 shown rotates in the direction of the arrow, the drive block 410 no longer slides along the guide slope 421c, but relies on the elastic reset of the elastic element 43 to make the drive disk 42 move along... Figure 2 During the movement to the right, the L-shaped groove 421a and the drive block 410 are pressed together (i.e. Figure 1 (as shown in the diagram), so that when the drive motor 40 reverses, it can drive the drive disk 42 along the direction indicated by the drive block 410. Figure 1 The arrow rotates in the opposite direction, eventually completing the reciprocating oscillation of several sets of air outlet blades 11.

[0052] Preferably, in this embodiment, the depth of the L-shaped groove 421a along the axis of the drive disk 42 is greater than the depth of the abutting surface 421b along the axis of the drive disk 42. This design effectively ensures that the drive block 410 and the abutting surface 421b can achieve a stable connection to the drive disk 42, thereby ensuring the smoothness of the first transmission assembly 2 driving the guide plate 10 to reciprocate. Furthermore, the greater depth of the L-shaped groove 421a than the abutting surface 421b ensures that the elastic element 43 has sufficient elastic reset space to push the drive disk 42 and the drive block 410 to abut against each other (i.e.,...). Figure 1 The state shown allows the drive disc 42 and the second transmission component 3 to fit tightly together, enhancing the efficiency of power transmission and the stability of the air outlet blades 11 during reciprocating oscillation.

[0053] The first transmission assembly 2 includes: a transmission disc 20, an assembly housing 12 mounted on the side wall of the air outlet housing 1, the transmission disc 20 being movably disposed within the assembly housing 12, a traction groove 200 formed on one side of the transmission disc 20, a first connecting portion 201 formed on the other side, a first engaging portion 422 formed on the drive disc 42, the first engaging portion 422 being movably connected to the first connecting portion 201; a first connecting rod 21 connected to the rotating shaft 100 of the air guide plate 10, a guide post 210 formed at the end of the first connecting rod 21, an arc-shaped limiting groove 120 formed on the side wall of the assembly housing 12, the guide post 210 passing through the arc-shaped limiting groove 120 and being movably engaged within the traction groove 200.

[0054] like Figures 2 to 4 As shown, at drive block 410 at Figure 3 At the position shown, the elastic element 43 is in a compressed state, and Figure 2 The first engaging portion 422 on the left side of the drive disc 42 is tightly connected to the first connecting portion 201 on the transmission disc 20. As the drive motor 40 rotates forward and drives the drive crank 41 to rotate, the drive disc 42 and the transmission disc 20 can be pushed along... Figure 3 The movement is in the opposite direction of the arrow shown. During this process, the rotation of the transmission disk 20 drives the guide column 210 to move along the arc-shaped limiting groove 120. In addition, the traction groove 200 on the assembly housing 12 restricts the position of the guide column 210, thereby driving the first connecting rod 21 to swing within a certain range. This is then converted into the reciprocating swing of the air guide plate 10 within the air outlet housing 1 through the rotating shaft 100, ultimately achieving a change in the airflow direction. It can be seen that the existence of the arc-shaped limiting groove 120 effectively limits the movement range of the guide column 210, avoids excessive swinging of the first connecting rod 21, and ensures the stability and safety of the system. The design of the traction groove 200 and the guide column 210 provides precise motion guidance, ensuring that the first connecting rod 21 can swing along a predetermined trajectory, thereby accurately controlling the swing angle and range of the air guide plate 10.

[0055] The second transmission assembly 3 includes: a track disk 30, which is movably disposed within the assembly housing 12. The outer wall of the track disk 30 has an arc-shaped guide groove 300, and the inner wall of the track disk 30 has a second connecting portion 301. The drive disk 42 has a second engaging portion 423 on the side opposite to the first engaging portion 422, and the second engaging portion 423 is movably connected to the second connecting portion 301; a second connecting rod 31, which is movably connected to several sets of air outlet blades 11. The end of the second connecting rod 31 has a traction column 310, and the outer wall of the assembly housing 12 has a guide groove 121 along its axial direction. The traction column 310 passes through the guide groove 121 and is movably engaged within the arc-shaped guide groove 300.

[0056] like Figures 2 to 4 As shown, when the drive block 410 is in Figure 1 When the position shown is reached (i.e., the drive block 410 is pressed against the L-shaped groove 421a), the elastic element 43 relies on elastic reset to move the drive disk 42 along... Figure 2 Pushing to the right causes the second engaging portion 423 on the right side of the drive disk 42 to be tightly connected to the second connecting portion 301 inside the track disk 30. Thus, when the drive motor 40 reverses and drives the drive crank 41 to rotate, the drive disk 42 and the track disk 30 can move along... Figure 1 The movement is in the opposite direction of the arrow shown. During this process, the rotation of the track disk 30 drives the traction column 310 to move along the arc-shaped guide groove 300. Furthermore, the guide groove 121 on the assembly housing 12 restricts the position of the traction column 310, allowing the second link 31 to reciprocate along the length of the guide groove 121, thereby driving several sets of air outlet blades 11, which are hinged to the second link 31, to oscillate back and forth. Similar to the technical effect of the first transmission component 2 described above, the presence of the guide groove 121 effectively limits the range of motion of the traction column 310, preventing excessive oscillation of the second link 31 and ensuring the stability and safety of the system. The design of the arc-shaped guide groove 300 and the traction column 310 provides precise motion guidance, ensuring that the second link 31 can oscillate along a predetermined trajectory, thereby accurately controlling the oscillation angle and range of the air outlet blades 11.

[0057] Preferably, in this embodiment, a buffer pad 420 is also installed on the drive disk 42. During the switching between the forward and reverse rotation states of the drive motor 40, the buffer pad 420 can effectively absorb the impact force generated when the drive disk 42 and the track disk 30 come into close contact, avoiding direct friction or collision that would shorten the service life of the structure. It also reduces the noise generated during operation, reduces unnecessary interference, and helps improve the overall comfort of the user.

[0058] Preferably, in this embodiment, the first connecting part 201, the second connecting part 301, the first engaging part 422, and the second engaging part 423 are all composed of a plurality of interconnected protruding teeth arranged in a circular array. The design of the protruding teeth provides a larger contact area and a stronger biting force, ensuring a firm connection between the drive disk 42 and the transmission disk 20 or the track disk 30, enhancing the reliability and stability of power transmission, avoiding power transmission errors caused by slight offsets, and ensuring the smoothness and stability of the air guide plate 10 and the air outlet blade 11 when swinging. It should be noted that the tight connection between the engaging part and the connecting part in this embodiment is not limited to the protruding teeth implementation in this embodiment. Other connection methods should also be within the scope of protection of this embodiment, such as the mating connection between the hole and the shaft.

[0059] Preferably, in this embodiment, potentiometers 101 are installed at the ends of several sets of air outlet blades 11 and air guide plates 10 rotating shafts 100. The two potentiometers 101 can record the real-time angular position of the air outlet blades 11 and air guide plates 10, and then feed back the electrical signal to the host. When the user controls the device through the large screen, the host can read the position of the blades and air guide plates 10 in real time, so as to better realize the individual control of the air outlet blades 11 and air guide plates 10 by a single motor.

[0060] The assembly housing 12 consists of a detachably connected mounting cylinder 122 and a cover 123. The drive motor 40 is detachably connected to the mounting cylinder 122. A mounting shaft 123a is formed on the cover 123. The transmission disk 20, the track disk 30, and the drive disk 42 are coaxially arranged on the mounting shaft 123a.

[0061] like Figure 2 As shown, in this embodiment, the cover 123 and the mounting cylinder 122 are detachably connected using a snap-fit ​​structure commonly used in machinery, facilitating the maintenance and replacement of their internal components by workers. The drive motor 40 can be connected to the mounting cylinder 122 using screws, bolts, or other fasteners, making maintenance and replacement of the drive motor 40 more convenient. Furthermore, a mounting shaft 123a extends from the cover 123 towards one side of the mounting cylinder 122. By coaxially mounting the transmission disc 20, the track disc 30, and the drive disc 42 on the mounting shaft 123a, and with the elastic return deformation of the elastic element 43, the smoothness and accuracy of the tight connection between the drive disc 42 and the transmission disc 20 or the track disc 30 are further improved, avoiding vibration and noise caused by eccentricity. Example

[0062] A single-motor controlled air outlet structure assembly includes an air outlet housing 1, an air guide plate 10 disposed therein, and several sets of air outlet blades 11; a first transmission component 2 and a second transmission component 3 movably disposed therein, the first transmission component 2 being movably connected to the air guide plate 10 and driving it to swing; the second transmission component 3 being movably connected to the air outlet blades 11 and driving them to swing within the air outlet housing 1; a drive component 4 having a forward rotation state and a reverse rotation state, when the drive component 4 is in the forward rotation state, the output end of the drive component 4 is movably connected to the second transmission component 3, used to drive the several sets of air outlet blades 11 to swing back and forth within the air outlet housing 1; when the drive component 4 switches to the reverse rotation state, the output end of the drive component 4 disengages from the second transmission component 3 and is movably connected to the first transmission component 2, used to control the air guide plate 10 to swing back and forth relative to the air outlet housing 1.

[0063] like Figure 5 As shown, this second embodiment is based on the structure of the first embodiment with corresponding improvements. While other structures remain the same, the difference between this second embodiment and the first embodiment is that the overall structure of each switching slot 421 is reversed compared to the first embodiment. (Refer to...) Figure 5 As shown, when the drive motor 40 is in the forward rotation state (i.e. Figure 5 When the direction indicated by the arrow is reached, the drive block 410 on the drive crank 41 can directly adhere to the side wall of the L-shaped groove 421a. That is to say, the elastic element 43 is in an expanded state at this time, and the drive block 410 does not apply a force to the drive disk 42 pressing against the elastic element 43, so that the drive disk 42 can be connected to the second transmission assembly 3 (i.e., the inner wall of the track disk 30 in embodiment 1), and then as the drive crank 41 moves along the direction indicated by the arrow, the drive block 410 can directly adhere to the side wall of the L-shaped groove 421a. Figure 5 During continuous rotation in the direction indicated by the arrow, several sets of guide vanes reciprocate within the air outlet housing 1; similarly, as the drive crank 41 drives the drive block 410 along... Figure 5 During the rotation in the opposite direction of the arrow (i.e., the drive motor 40 is in reverse), the drive block 410 moves from the L-shaped groove 421a along the guide slope 421c towards the abutting surface 421b. During this process, the drive block 410 presses against the guide slope 421c and applies a certain squeezing force to the drive disk 42, so that the elastic member 43 gradually compresses to allow the drive disk 42 to connect with the first transmission assembly 2 (i.e., the first connecting part 201 on the transmission disk 20 in the embodiment). After the drive block 410 and the abutting surface 421b are pressed together and continue to move along the guide slope 421c, the drive block 410 moves towards the abutting surface 421b. Figure 5 During the rotation in the opposite direction of the arrow shown, the air guide plate 10 can reciprocate within the air outlet housing 1. Therefore, by changing the overall structural position of the switching slot 421, the drive motor 40 can switch between forward and reverse rotation to adjust the positions of several sets of air outlet blades 11 and air guide plates 10 relative to the air outlet housing 1, ensuring that user needs are met.
