[0010] In the above-mentioned single-motor controlled air outlet structure assembly, each of the switching slots includes an L-shaped slot and a pressing surface opened along the axial direction of the driving disk, and the L-shaped slot and the pressing surface are connected by a guiding inclined surface.

[0011] In the above-mentioned single-motor controlled air outlet structure assembly, the depth of the L-shaped groove along the axis direction of the driving disk is greater than the depth of the abutting surface along the axis direction of the driving disk.

[0012] In the above-mentioned single-motor controlled air outlet structure assembly, the first transmission component includes: A transmission plate, an assembly shell is installed on the side wall of the air outlet shell, the transmission plate is movably arranged in the assembly shell, a traction groove is formed on one side of the transmission plate, and a first connecting portion is formed on the other side, a first clamping portion is formed on the drive plate, and the first clamping portion is movably connected to the first connecting portion; A first connecting rod is connected to the rotating shaft of the air guide plate, a guide column is formed at the end of the first connecting rod, an arc-shaped limiting groove is formed on the side wall of the assembly shell, and the guide column passes through the arc-shaped limiting groove and is movably clamped in the traction groove.

[0013] In the above-mentioned single-motor controlled air outlet structure assembly, the second transmission component includes: A track plate, movably disposed in the assembly housing, an arc-shaped guide groove is formed on the outer wall of the track plate, a second connecting portion is formed on the inner wall of the track plate, a second clamping portion is formed on a side of the drive plate away from the first clamping portion, and the second clamping portion is movably connected to the second connecting portion; The second connecting rod is movably connected to a plurality of groups of air outlet blades. A traction column is formed at the end of the second connecting rod. A guide groove is formed on the outer wall of the assembly shell along its axial direction.

[0018] (3) The depth of the L-shaped groove along the axis of the driving disk is greater than the depth of the abutting surface along the axis of the driving disk. This design, combined with the elastic deformation of the elastic part, ensures that the driving disk can be stably and flexibly connected to the transmission disk or the track disk when the driving motor switches between the forward and reverse states, thereby improving the smoothness and stability of the swing of the air guide plate and the air outlet blade controlled by the single motor.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. Example

[0023] like Figures 1 to 4 As shown, the present invention is a single-motor controlled air outlet structure assembly, including an air outlet shell 1 and an air guide plate 10 and a plurality of groups of air outlet blades 11 arranged inside the air outlet shell; a first transmission component 2 and a second transmission component 3 are movably arranged, the first transmission component 2 is movably connected to the air guide plate 10 and drives it to swing; the second transmission component 3 is movably connected to the air outlet blades 11 and drives it to swing in the air outlet shell 1; a driving member 4 having a forward rotation state and a reverse rotation state, when the driving member 4 is in the forward rotation state, the output end of the driving member 4 is movably connected to the first transmission component 2, and is used to drive the air guide plate 10 to swing back and forth in the air outlet shell 1; when the driving member 4 is switched to the reverse state, the output end of the driving member 4 is separated from the first transmission component 2, and is movably connected to the second transmission component 3, and is used to control the plurality of groups of air outlet blades 11 to swing back and forth relative to the air outlet shell 1.

[0024] This solution is mainly to achieve a single motor to alternately control the swing of the air guide plate 10 and the air outlet blade 11. Specifically, Figures 1 to 4As shown, the air guide plate 10 is located at the air inlet of the air outlet housing 1, and a plurality of groups of air outlet blades 11 are distributed at the air outlet of the air outlet housing 1. When the user chooses to adjust the air flow direction of the air inlet, the control system issues a command to make the driving member 4 enter the forward rotation state (such as Figure 1 The state shown in the figure) allows the output end of the driving member 4 to be movably connected to the first transmission component 2 by mechanical connection or electromagnetic coupling. Since one end of the first transmission component 2 is connected to the output end of the driving member 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 swinging, thereby driving the air guide plate 10 to swing back and forth in the air outlet shell 1 to change the direction of the air flow; similarly, when the user wants to adjust the air flow width or range, the control system can switch the driving member 4 to the reverse state. At this time, the output end of the driving member 4 is disengaged from the first transmission component 2 and is movably connected to the second transmission component 3. As the second transmission component 3 receives the power from the driving member 4 and transmits it to the air outlet blades 11, the air outlet blades 11 can swing back and forth relative to the air outlet shell 1, thereby adjusting the direction and size of the air flow. It can be seen that the structure uses a single drive component 4 instead of multiple motors, which greatly reduces the number of parts and reduces the difficulty and cost of assembly; not only that, this solution saves the installation space of the entire air outlet structure, allowing the product design to be more compact, which not only helps to reduce the overall size, but also makes the equipment easier to adapt to various installation environments, bringing great convenience to the user's operation.

[0025] The driving member 4 includes: a driving motor 40, a driving end of the driving motor 40 is coaxially connected to a driving crank 41; a driving disk 42 and an elastic member 43, both of which are coaxially arranged with the driving crank 41, and the driving disk 42 is movably pressed against the driving crank 41; the two ends of the elastic member 43 are respectively connected to the driving disk 42 and the first transmission component 2; the driving disk 42 can squeeze the elastic member 43 when the driving motor 40 drives the driving crank 41 to rotate forward, so that the driving disk 42 is movably pressed against the first transmission component 2 to drive the air guide plate 10 to swing; and when the driving motor 40 is reversed, the elastic reset of the elastic member 43 pushes the driving disk 42 to disengage from the first transmission component 2 and movably press against the second transmission component 3 to drive the air outlet blade 11 to swing.

[0026] like Figures 1 to 4 As shown, in this embodiment, an elastic member 43 is provided between the end of the first transmission assembly 2 away from the air guide plate 10 and the driving disk 42. When the driving motor 40 (in this embodiment, a stepping motor, a servo motor or other driving devices can be used instead) switches from the reverse state to the forward state, the driving crank 41 can be Figure 1 The positions shown are in a clockwise direction (i.e. Figure 1 direction of the arrow) to Figure 3In this process, the drive disc 42 is subjected to the axial extrusion force of the drive crank 41, so that the elastic member 43 is compressed to connect the drive disc 42 with the first transmission assembly 2. Figure 3 The driving crank 41 in the state shown continues to rotate (along Figure 1 During the process of rotating the drive plate 42 (in the direction indicated by the arrow), the rotational motion of the drive disk 42 can be converted into a force for the first transmission assembly 2 to drive the air guide plate 10 to swing back and forth; and when the drive motor 40 is switched to the reverse state, the drive crank 41 can be driven to swing along the Figure 3 The driving plate 42 is rotated in the direction of the arrow shown in the figure. At this time, the driving plate 42 is no longer subjected to the extrusion force of the driving crank 41, and the elastic restoring action of the elastic member 43 pushes the Figure 2 The driving disc 42 shown is movably connected to the second transmission assembly 3 during the rightward movement. Under the continuous rotation of the driving crank 41, the rotational motion of the driving disc 42 can be converted into a force for the second transmission assembly 3 to drive a plurality of groups of air outlet blades 11 to swing back and forth. The structure introduces a combined design of the driving crank 41, the driving disc 42 and the elastic member 43, which reduces the additional switching mechanism or complex electronic control system, and reduces the overall complexity and manufacturing cost; at the same time, the design of the elastic member 43 not only provides a reliable switching function, but also plays a buffering role, reduces the impact of the impact load on the transmission assembly, and improves the reliability and durability of the entire system.

[0027] Preferably, the elastic member 43 in this embodiment can be replaced by other elastic devices such as a compression spring and a return spring.

[0028] A plurality of driving blocks 410 are evenly distributed on the driving crank 41, and a plurality of switching grooves 421 are evenly spaced in a ring shape at the end of the driving disk 42. The driving block 410 movably extends into the switching groove 421 and can be reciprocated between the first position and the second position of the switching groove 421; when the driving block 410 is in the first position of the switching groove 421, the driving disk 42 is movably connected to the first transmission assembly 2, so as to realize the swing of the air guide plate 10 in the air outlet housing 1; when the driving block 410 is switched from the first position to the second position, the driving disk 42 can be movably connected to the second transmission assembly 3 due to the elastic reset of the elastic member 43, so as to drive the air outlet blades 11 to swing back and forth relative to the air outlet housing 1.

[0029] In this embodiment, each driving block 410 corresponds to a switching slot 421, and the driving block 410 can switch between a first position and a second position in the switching slot 421. By virtue of the equidistant distribution of the switching slots 421, uniform switching timing is provided, thereby avoiding functional failure caused by position deviation. Specifically, Figure 1 and Figure 3 As shown, the drive block 410 is composed of Figure 1When the first position of the switching slot 421 is rotated in the direction of the arrow, the driving block 410 will inevitably exert a certain extrusion force on the driving disk 42. Figure 2 The elastic member 43 is gradually compressed to the left and finally the driving plate 42 and the first transmission assembly 2 are connected. It is worth noting that the driving block 410 also rotates to the right at this time. Figure 3 In the second position of the switching slot 421, the drive block 410 no longer applies the drive disk 42 along the Figure 2 The force of moving to the left, along with the driving crank 41 driving the driving block 410 Figure 3 When the drive block 410 is rotated in the opposite direction of the arrow direction, the drive crank 41, the drive disk 42 and the first transmission assembly 2 connected thereto can rotate synchronously to realize the swing of the air guide plate 10. Therefore, under the cooperation of the elastic member 43 and the switching slot 421, the accuracy and reliability of the switching between different transmission assemblies of the drive disk 42 are ensured. Figure 3 When the position shown in the figure rotates in the direction of the arrow, the driving block 410 no longer applies a squeezing force to the driving disk 42, and relies on the elastic restoring force of the elastic member 43 to push the driving disk 42 along the Figure 2 Move rightward until the drive block 410 is at Figure 1 When the switching slot 421 is in the first position, the connection between the driving disk 42 and the second transmission assembly 3 is also completed, and finally the reciprocating swing of the air outlet blade 11 can be achieved when the driving motor 40 continues to reverse.

[0030] Each switching slot 421 includes an L-shaped slot 421 a and a pressing surface 421 b opened along the axial direction of the driving disk 42 . The L-shaped slot 421 a and the pressing surface 421 b are connected by a guiding inclined surface 421 c.

[0031] Further, if Figure 2 As shown, each switching groove 421 in this embodiment is formed by an L-shaped groove 421a and a pressing surface 421b. Figure 1 As shown in FIG. 1 , when the driving block 410 falls into the L-shaped groove 421a (i.e., the first position of the switching groove 421), as the driving crank 41 moves along Figure 1 When the driving block 410 rotates in the direction indicated by the arrow, the driving disk 42 can be pushed along Figure 2 Move leftward and connect to the first transmission assembly 2 until the driving block 410 is pressed against the pressing surface 421b (such as Figure 3In the state shown, i.e. the second position of the switching slot 421), the elastic member 43 no longer continues to compress and deform, and by relying on the abutment between the driving block 410 and the abutment surface 421b, the first transmission assembly 2 can be driven to rotate and converted into the reciprocating swing of the air guide plate 10. In the above process, the guiding slope 421c formed between the two provides a clear path for the driving block 410, ensuring the stability of the driving block 410 during the conversion to the swinging of the air guide plate 10, avoiding functional failure due to position deviation, and at the same time utilizing the design of the L-shaped slot 421a and the abutment surface 421b to ensure the accuracy of the driving block 410 when it is in the first position and the second position of the switching slot 421, thereby increasing the efficiency and stability of power transmission, and providing a guarantee for the smoothness and stability of the reciprocating swing of the air guide plate 10 and the air outlet blade 11. It should be noted that when the driving block 410 is Figure 3 When the second position of the switching slot 421 is rotated in the direction of the arrow, the driving block 410 no longer slides along the guide slope 421c, but relies on the elasticity of the elastic member 43 to reset, so that the driving disk 420 moves along the guide slope 421c. Figure 2 During the rightward movement, the L-shaped groove 421a and the driving block 410 are pressed against each other (i.e. Figure 1 410) so that when the drive motor 40 is reversed, the drive block 410 can push the drive disk 42 along the Figure 1 The blades 11 rotate in the opposite direction of the arrow, and finally the reciprocating swing of the plurality of groups of the air outlet blades 11 is completed.

[0032] Preferably, the depth of the L-shaped groove 421a in the present embodiment along the axial direction of the driving disk 42 is greater than the depth of the abutting surface 421b along the axial direction of the driving disk 42. This design effectively ensures that the driving block 410 and the abutting surface 421b can cooperate to achieve a stable connection with the driving disk 42, thereby providing a guarantee for the smoothness of the first transmission assembly 2 when driving the air guide plate 10 to swing back and forth; and the depth of the L-shaped groove 421a is greater than the depth of the abutting surface 421b, ensuring that the elastic member 43 has sufficient elastic reset space to push the driving disk 42 and the driving block 410 to abut against each other (i.e. Figure 1 The state shown in the figure) enables the driving disc 42 and the second transmission assembly 3 to fit closely, thereby enhancing the efficiency of power transmission and the stability of the air outlet blades 11 during reciprocating swing.

[0033] The first transmission assembly 2 includes: a transmission disk 20, an assembly shell 12 is installed on the side wall of the air outlet shell 1, the transmission disk 20 is movably arranged in the assembly shell 12, a traction groove 200 is formed on one side of the transmission disk 20, and a first connecting portion 201 is formed on the other side, a first clamping portion 422 is formed on the driving disk 42, and the first clamping portion 422 is movably connected to the first connecting portion 201; a first connecting rod 21, which is connected to the rotating shaft 100 of the air guide plate 10, and a guide column 210 is formed at the end of the first connecting rod 21, and an arc-shaped limiting groove 120 is formed on the side wall of the assembly shell 12, and the guide column 210 passes through the arc-shaped limiting groove 120 and is movably clamped in the traction groove 200.

[0034] like Figures 2 to 4 As shown, at the drive block 410 Figure 3 When the elastic member 43 is in the position shown, it is in a compressed state. Figure 2 The first engaging portion 422 on the left side of the driving disk 42 is tightly connected with the first connecting portion 201 on the transmission disk 20. As the driving motor 40 rotates forward and drives the driving crank 41 to rotate, the driving disk 42 and the transmission disk 20 can be pushed along the Figure 3 The first connecting rod 210 moves in the opposite direction of the arrow shown in the figure. During this process, the rotation of the transmission plate 20 drives the guide column 210 to move along the arc-shaped limit groove 120. In addition, the position of the guide column 210 is limited by the traction groove 200 on the assembly shell 12, thereby driving the first connecting rod 21 to swing within a certain range, and converting it into a reciprocating swing of the air guide plate 10 in the air outlet shell 1 through the rotating shaft 100, and finally realizing the change of the airflow direction. It can be seen that the existence of the arc-shaped limit 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 movement guidance, ensuring that the first connecting rod 21 can swing according to the predetermined trajectory, thereby accurately controlling the swing angle and range of the air guide plate 10.

[0035] The second transmission assembly 3 includes: a track disk 30, which is movably arranged in the assembly shell 12, and the outer wall of the track disk 30 is formed with an arc-shaped guide groove 300, and the inner wall of the track disk 30 is formed with a second connecting portion 301, and the side of the driving disk 42 away from the first clamping portion 422 is formed with a second clamping portion 423, and the second clamping portion 423 is movably connected to the second connecting portion 301; a second connecting rod 31, which is movably connected to a plurality of groups of air outlet blades 11, and a traction column 310 is formed at the end of the second connecting rod 31, and the outer wall of the assembly shell 12 is formed with a guide groove 121 along its axial direction, and the traction column 310 passes through the guide groove 121 and is movably clamped in the arc-shaped guide groove 300.

[0036] like Figures 2 to 4 As shown, when the drive block 410 is in Figure 1When the drive block 410 is in the position shown in FIG. 1 (i.e., the drive block 410 is pressed against the L-shaped groove 421a), the elastic member 43 at this time relies on elastic reset to move the drive disk 42 along the Figure 2 Push rightward, so that the second engaging portion 423 on the right side of the driving disk 42 is tightly connected with the second connecting portion 301 in the track disk 30, so that when the driving motor 40 is reversed and drives the driving crank 41 to rotate, the driving disk 42 and the track disk 30 can move along the track disk 30. Figure 1 The second connecting rod 310 moves in the opposite direction of the arrow shown in the figure. During this process, the rotation of the track disk 30 drives the traction column 310 to move along the arc-shaped guide groove 300. In addition, the guide groove 121 on the assembly shell 12 limits the position of the traction column 310, so that the second connecting rod 31 can drive several groups of air outlet blades 11 that are movably hinged to the second connecting rod 31 to swing back and forth during the reciprocating movement along the length direction of the guide groove 121. The technical effect of the first transmission assembly 2 is the same as that of the above-mentioned first transmission assembly 2. The existence of the guide groove 121 effectively limits the movement range of the traction column 310, avoids excessive swinging of the second connecting rod 31, and ensures the stability and safety of the system. The design of the arc-shaped guide groove 300 and the traction column 310 provides precise movement guidance, ensuring that the second connecting rod 31 can swing according to the predetermined trajectory, thereby accurately controlling the swing angle and range of the air outlet blades 11.

[0037] Preferably, in this embodiment, a buffer pad 420 is also installed on the drive disk 42. During the switching process between the forward rotation state and the reverse state of the drive motor 40, the buffer pad 420 can effectively absorb the impact force generated at the moment of close contact between the drive disk 42 and the track disk 30, avoiding direct friction or collision and shortening the service life of the structure. At the same time, it also reduces the noise generated during operation, reduces unnecessary interference, and is conducive to improving the overall comfort of the user when using it.

[0038] Preferably, the first connecting portion 201, the second connecting portion 301, the first engaging portion 422 and the second engaging portion 423 in the present embodiment are all composed of a plurality of mutually connected convex teeth arranged in a circular array. The design of the convex teeth provides a larger contact area and a stronger bite 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 wind guide plate 10 and the wind outlet blades 11 when they swing. It should be noted that the tight connection between the engaging portion and the connecting portion in the present embodiment is not limited to the convex teeth in the present embodiment, and other connection methods should also fall within the scope of protection of the present embodiment, such as the matching connection between the hole shaft, etc.

[0039] Preferably, in this embodiment, potentiometers 101 are installed at the ends of the rotating shafts 100 of several groups of air outlet blades 11 and air guide plates 10. The two potentiometers 101 can record the real-time angular positions of the air outlet blades 11 and the air guide plates 10, and then feed back electrical signals to the host. When the user controls through the large screen, the host can read the positions of the blades and the air guide plates 10 in real time, so as to better realize the separate control of the air outlet blades 11 and the air guide plates 10 by a single motor.

[0040] The assembly shell 12 is composed of a detachably connected mounting cylinder 122 and a cover 123, and the drive motor 40 is detachably connected to the mounting cylinder 122; a mounting shaft 123a is formed on the cover 123, and the transmission disk 20, the track disk 30 and the drive disk 42 are coaxially arranged on the mounting shaft 123a.

[0041] like Figure 2 As shown, the cover 123 and the mounting cylinder 122 in this embodiment are detachably connected by a snap-fit ​​structure commonly used in machinery, so as to facilitate the maintenance and replacement of the internal parts by workers. The drive motor 40 can be connected to the mounting cylinder 122 by screws, screws and other fasteners, making the maintenance and replacement of the drive motor 40 more convenient. In addition, the cover 123 extends to one side of the mounting cylinder 122 with a mounting shaft 123a. By coaxially arranging the transmission disk 20, the track disk 30 and the drive disk 42 on the mounting shaft 123a, the elastic reset deformation of the elastic member 43 is cooperated to further improve the smoothness and accuracy of the drive disk 42 when it is tightly connected with the transmission disk 20 or the track disk 30, and avoid vibration and noise caused by eccentricity. Example

[0042] A single-motor controlled air outlet structure assembly comprises an air outlet shell 1, an air guide plate 10 and a plurality of groups of air outlet blades 11 arranged inside the air outlet shell; a first transmission component 2 and a second transmission component 3 are movably arranged, the first transmission component 2 is movably connected to the air guide plate 10 and drives it to swing; the second transmission component 3 is movably connected to the air outlet blades 11 and drives it to swing inside the air outlet shell 1; a driving member 4 having a forward rotation state and a reverse rotation state, when the driving member 4 is in the forward rotation state, the output end of the driving member 4 is movably connected to the second transmission component 3, and is used to drive the plurality of groups of air outlet blades 11 to swing back and forth inside the air outlet shell 1; when the driving member 4 is switched to the reverse rotation state, the output end of the driving member 4 is disengaged from the second transmission component 3, and is movably connected to the first transmission component 2, and is used to control the air guide plate 10 to swing back and forth relative to the air outlet shell 1.

[0043] like Figure 5As shown, the second embodiment is based on the structure of the first embodiment and makes corresponding improvements. When other structures are the same, the second embodiment is different from the first embodiment in that the overall structure of each switching slot 421 is opposite to that of the first embodiment. Figure 5 As shown, when the drive motor 40 is in the forward rotation state (i.e. Figure 5 In the direction indicated by the arrow), the driving block 410 on the driving crank 41 can be directly attached to the side wall of the L-shaped groove 421a, that is, the elastic member 43 is in an expanded state at this time, and the driving block 410 does not apply the force of the driving disk 42 to squeeze the elastic member 43, so that the driving disk 42 can be connected to the second transmission component 3 (that is, the inner wall of the track disk 30 in the first embodiment), and then as the driving crank 41 moves along Figure 5 During the continuous rotation in the direction indicated by the arrow, a plurality of groups of air guide blades are realized to swing back and forth in the air outlet housing 1; similarly, when the driving crank 41 drives the driving block 410 along Figure 5 During the rotation in the opposite direction of the arrow shown (i.e., the driving motor 40 is in the reverse state), the driving block 410 moves from the L-shaped groove 421a along the guiding inclined surface 421c to the pressing surface 421b. During this process, the driving block 410 presses against the guiding inclined surface 421c and applies a certain extrusion force to the driving disk 42, so that the elastic member 43 is gradually compressed to allow the driving disk 42 to achieve connection with the first transmission assembly 2 (i.e., the first connecting portion 201 on the transmission disk 20 in the embodiment). When the driving block 410 and the pressing surface 421b are pressed against each other and continue to move along the L-shaped groove 421a, the driving block 410 is pressed against the guiding inclined surface 421c and applies a certain extrusion force to the driving disk 42. Figure 5 During the rotation in the opposite direction of the arrow, the reciprocating swing of the air guide plate 10 in the air outlet housing 1 can be completed. It can be seen that, in the case of changing the overall structural position of the switching slot 421, the adjustment function of the positions of several groups of air outlet blades 11 and the air guide plate 10 relative to the air outlet housing 1 can be completed by switching the driving motor 40 in the same forward and reverse states, so as to ensure that the use requirements of the user are met.
