[0044] The utility model provides a kind of coupling.

[0045] Please refer to Figure 1 And Figure 4 In an embodiment of the utility model, the coupling includes transmission block 10 and limit seat 20, transmission block 10 is used to be connected with the driving motor 1 of driving module;Limit seat 20 is connected with one side of transmission block 10, is used to be cooperated with the hanging rod 2 of driving module and is inserted;And hanging rod 2 can rotate relative to limit seat 20, limit seat 20 is also used to limit the hanging rod 2 after rotation.

[0046] In an embodiment of the present application, the transmission block 10 is one of the core components of the coupling, and its main function is to connect the rotating shaft of the driving motor 1. Through this connection, the transmission block 10 can transmit the power of the motor to the entire coupling, thereby realizing the driving function of the air conditioner wind deflector. The limiting seat 20 is another key component of the coupling, which is connected to one side of the transmission block 10 and cooperates with the hanging rod 2. The main function of the limiting seat 20 is to provide a rotatable support point for the hanging rod 2, and to realize the limiting function of the rotating angle of the hanging rod 2 through its internal structure design. The structure design of the limiting seat 20 allows the hanging rod 2 to rotate relatively inside it, thereby allowing the air conditioner wind deflector to rotate freely within a certain range. At the same time, the limiting seat 20 also has the function of limiting the hanging rod 2 after rotation, preventing the hanging rod 2 from rotating excessively, thereby ensuring that the rotating angle of the air conditioner wind deflector is always within the preset range.

[0047] In the working process, the driving motor 1 transmits power to the limiting seat 20 through the transmission block 10, and then transmits power to the hanging rod 2 through the limiting seat 20, so that the hanging rod 2 rotates in the limiting seat 20, driving the air conditioner wind deflector to realize angle adjustment. When the hanging rod 2 rotates to the preset position, the limiting seat 20 will prevent the hanging rod 2 from continuing to rotate, thereby realizing accurate control of the rotating angle of the air conditioner wind deflector. This design not only simplifies the transmission structure, but also improves the stability and reliability of the rotation of the air conditioner wind deflector.

[0048] When the driving motor 1 starts, the rotating shaft of the driving motor 1 transmits power to the limiting seat 20 through the transmission block 10. The limiting seat 20 further transmits power to the hanging rod 2, thereby driving the air conditioner wind deflector to rotate. When it is necessary to manually adjust the angle of the air conditioner wind deflector, the user can manually rotate the hanging rod 2 to make the hanging rod 2 rotate in the limiting seat 20. Since the limiting seat 20 is also used to limit the hanging rod 2 after rotation, the hanging rod 2 can stop at any angle and remain stable. This design allows users to flexibly adjust the angle of the air conditioner wind deflector as needed without damaging the driving device.

[0049] The present application directly realizes the angle limiting function on the mechanical level by setting the limiting seat 20 on one side of the transmission block 10, without the need for complex electronic control or additional transmission devices. This design greatly simplifies the overall structure of the coupling, reduces production costs and maintenance difficulty. Since the limiting seat 20 is also used to limit the hanging rod 2 after rotation, the user can manually rotate the hanging rod 2 to realize angle adjustment of the air conditioner wind deflector without damaging the driving device. This design not only increases the adjustment mode of the air conditioner wind deflector, but also improves its flexibility and user experience.

[0050] In the first embodiment, please refer to Figures 1 to 3The limiting seat 20 includes a first elastic clamping arm 21 and a second elastic clamping arm 22. One end of the first elastic clamping arm 21 is connected with the transmission block 10. One end of the second elastic clamping arm 22 is connected with one end of the first elastic clamping arm 21, and encloses a clamping groove 20a. The clamping groove 20a is used for clamping one end of the hanging rod 2. The other end of the first elastic clamping arm 21 away from the transmission block 10 is spaced apart from the other end of the second elastic clamping arm 22 away from the transmission block 10 to form an expansion space.

[0051] The first elastic clamping arm 21 is an important component of the limiting seat 20, and one end of the first elastic clamping arm 21 is fixedly connected with the transmission block 10. This connection mode ensures that the clamping arm has a stable support point during work. The main function of the first elastic clamping arm 21 is to form a clamping groove 20a together with the second elastic clamping arm 22 for clamping one end of the hanging rod 2. The elastic design of the first elastic clamping arm 21 allows the clamping arm to deform within a certain range, thereby adapting to hanging rods 2 of different sizes or shapes, while providing sufficient clamping force to maintain the stability of the hanging rod 2.

[0052] The second elastic clamping arm 22 is connected with one end of the first elastic clamping arm 21 and encloses the clamping groove 20a together with the first elastic clamping arm 21. The second elastic clamping arm 22 also has elasticity and can work cooperatively with the first elastic clamping arm 21 to achieve clamping of the end of the hanging rod 2. The elastic property of the second elastic clamping arm 22 not only allows the clamping groove 20a to adapt to the shape of the hanging rod 2 during clamping, but also provides a certain buffering effect after clamping, reducing damage caused by external impact.

[0053] The clamping groove 20a is a structure formed by the first elastic clamping arm 21 and the second elastic clamping arm 22, and its main function is to clamp one end of the hanging rod 2. The shape and size of the clamping groove 20a are designed to match the end of the hanging rod 2, which can ensure that the hanging rod 2 is stable and firm during clamping. The design of the clamping groove 20a not only considers the stability of clamping, but also takes into account the rotational flexibility of the hanging rod 2, so that the hanging rod 2 can rotate freely in the clamping groove 20a.

[0054] The expansion space is the interval between the other end of the first elastic clamping arm 21 and the other end of the second elastic clamping arm 22 away from the transmission block 10. This space exists to allow the elastic clamping arm to freely expand and contract when clamping the hanging rod 2, thereby adapting to the ends of hanging rods 2 of different sizes. The design of the expansion space allows the clamping groove 20a to have a certain elastic deformation ability, further improving the adaptability and reliability of clamping.

[0055] When the end of the hanging rod 2 is inserted into the clamping groove 20a, the first elastic clamping arm 21 and the second elastic clamping arm 22 will be elastically deformed according to the shape and size of the hanging rod 2. During the process of gradually entering the clamping groove 20a, the elastic clamping arm will contract towards the expansion space direction, thereby adapting to the shape of the hanging rod 2. This elastic deformation enables the clamping groove 20a to closely fit the end of the hanging rod 2, ensuring that the hanging rod 2 does not loosen during the clamping process.

[0056] After the end of the hanging rod 2 is clamped, the user can manually rotate the hanging rod 2. Due to the elastic properties of the elastic clamping arm, the clamping groove 20a can provide a certain friction during the rotation of the hanging rod 2, so that the hanging rod 2 can stop and remain stable at any angle. The size of this friction can be controlled by adjusting the elastic coefficient of the elastic clamping arm, thereby achieving the adjustment of the rotation resistance of the hanging rod 2.

[0057] When the hanging rod 2 is rotated to the desired angle, the friction of the elastic clamping arm will prevent the hanging rod 2 from continuing to rotate, thereby achieving angle limiting. At the same time, the existence of the expansion space allows the elastic clamping arm to make slight elastic adjustments during the rotation of the hanging rod 2, further ensuring the stability of the hanging rod 2 at any angle.

[0058] The first embodiment enables the clamping groove 20a to adapt to the ends of hanging rods 2 of different sizes and shapes through the elastic design of the first elastic clamping arm 21 and the second elastic clamping arm 22, greatly improving the versatility and compatibility of the limiting seat 20. This design not only reduces the installation problems caused by the size mismatch of the hanging rod 2, but also reduces the production cost. The elastic properties of the elastic clamping arm enable the hanging rod 2 to rotate freely within the clamping groove 20a, while remaining stable when stopped at any angle. This design not only improves the adjustment flexibility of the air conditioner wind deflector, but also avoids damage to the drive device caused by manual adjustment, prolonging the service life of the product.

[0059] In the first embodiment, please refer to Figures 1 to 3 , the groove wall of the clamping groove 20a is provided with a first frictional clamping tooth 20b.

[0060] The clamping groove 20a is a key structure inside the limiting seat 20, which is enclosed by the first elastic clamping arm 21 and the second elastic clamping arm 22. Its main function is to clamp one end of the hanging rod 2, providing stable support and rotation basis for the hanging rod 2. The shape and size of the clamping groove 20a are designed to match the end of the hanging rod 2, ensuring that the hanging rod 2 can be smoothly inserted and firmly clamped. The first frictional clamping tooth 20b is a microstructure provided on the groove wall of the clamping groove 20a, usually in a zigzag or wavy distribution. Its main role is to cooperate with the clamping convex structure at the end of the hanging rod 2 to provide sufficient friction and clamping effect. The design of the first frictional clamping tooth 20b not only prevents the hanging rod 2 from loosening during the clamping process, but also achieves precise limiting when the hanging rod 2 is rotated to any angle.

[0061] The first frictional catch 20b tightly fits with the catch convex structure at the end of the hanging rod 2, providing sufficient friction and catch effect, so that the hanging rod 2 can be stably clamped in the clamping groove 20a. This design not only reduces the loosening of the hanging rod 2 caused by external force impact, but also improves the reliability of clamping. The design of the first frictional catch 20b allows the hanging rod 2 to stop and remain stable at any angle during rotation. This angle limiting function not only improves the adjustment accuracy of the air conditioner air baffle, but also allows users to flexibly adjust the angle of the air baffle according to their needs, enhancing the user experience of the product.

[0062] In the first embodiment, please refer to Figures 1 to 3 , a relief groove 20c is provided between the limiting seat 20 and the transmission block 10, which is used to accommodate the protruding structure at one end of the hanging rod 2.

[0063] The relief groove 20c is a special structure provided between the limiting seat 20 and the transmission block 10, and its main function is to provide a space for the protruding structure at the end of the hanging rod 2. The design of the relief groove 20c allows the protruding structure at the end of the hanging rod 2 to pass smoothly during installation and rotation, without interfering with the limiting seat 20 or the transmission block 10. This design is crucial for ensuring smooth rotation of the hanging rod 2 and stability of the overall structure.

[0064] When installing the hanging rod 2, the protruding structure at the end of the hanging rod 2 is first aligned with the position of the relief groove 20c. The shape and size of the relief groove 20c are designed to allow the protruding structure to smoothly enter the interior of the limiting seat 20 without interfering with the limiting seat 20 or the transmission block 10. This design ensures that the hanging rod 2 can be quickly and accurately installed in place.

[0065] When the hanging rod 2 rotates, the protruding structure at its end will slide within the relief groove 20c. The design of the relief groove 20c not only provides sufficient space for the protruding structure, but also ensures that the hanging rod 2 can smoothly pass through the connection area between the limiting seat 20 and the transmission block 10 during rotation. This design avoids the phenomenon of jamming caused by structural interference, improving the flexibility of the hanging rod 2 rotation.

[0066] The relief groove 20c provides sufficient space for the protruding structure at the end of the hanging rod 2, allowing the hanging rod 2 to smoothly pass through the connection area between the limiting seat 20 and the transmission block 10 during rotation. This design avoids the phenomenon of jamming caused by structural interference, improving the flexibility and reliability of the hanging rod 2 rotation.

[0067] In the first embodiment, please refer to Figures 1 to 3 , the groove bottom of the relief groove 20c is provided with a limiting counterbore, which is used for the protruding structure at one end of the hanging rod 2 to catch and limit.

[0068] The limiting counterbore is a special structure set at the bottom of the avoidance groove 20c, and its main function is to provide a clamping limiting point for the protruding structure at the end of the hanging rod 2. The shape and size of the limiting counterbore are designed to match the protruding structure at the end of the hanging rod 2, which can ensure that the protruding structure can be clamped into the limiting counterbore when it is rotated to a specific position, thereby achieving precise angle limiting.

[0069] In the second embodiment, please refer to Figure 4 and Figure 5 , the limiting seat 20 includes a seat plate 23 and a limiting column 24, the seat plate 23 is connected with one end of the transmission block 10; the limiting column 24 is connected with the end of the seat plate 23 away from the transmission block 10, used for inserting into the insertion hole 2b of the hanging rod 2 of the driving module.

[0070] The seat plate 23 is the basic structure part of the limiting seat 20, and one end of it is connected with the transmission block 10, playing a supporting and connecting role. The design of the seat plate 23 not only needs to ensure the stable connection with the transmission block 10, but also needs to provide a mounting basis for the limiting column 24. The seat plate 23 usually has high strength and stability to withstand the torque generated when the hanging rod 2 rotates. The limiting column 24 is another key structure of the limiting seat 20, and one end of it is connected with the end of the seat plate 23 away from the transmission block 10. The main function of the limiting column 24 is to cooperate with the insertion hole 2b of the hanging rod 2 to realize the insertion and positioning of the hanging rod 2.

[0071] The insertion hole 2b of the hanging rod 2 is a structure set at one end of the hanging rod 2, used for cooperating with the limiting column 24. The shape and size of the insertion hole 2b are designed to match the limiting column 24, ensuring that the hanging rod 2 can be stably inserted into the limiting column 24 and maintain good connection state during rotation.

[0072] When the driving motor 1 starts, power is transmitted to the limiting seat 20 through the transmission block 10. The limiting column 24 tightly cooperates with the insertion hole 2b of the hanging rod 2, further transmitting power to the wind plate body through the hanging rod 2 to drive the wind plate body to rotate. During rotation, the seat plate 23 provides stable support for the limiting column 24, ensuring smooth and reliable rotation of the hanging rod 2.

[0073] When the hanging rod 2 rotates to the required angle, other structures in the limiting seat 20 (such as the first friction clamping tooth 20b or the limiting counterbore) will cooperate with the protruding structure at the end of the hanging rod 2 to achieve angle limiting. The design of the limiting column 24 not only allows the hanging rod 2 to rotate freely within a certain range, but also provides sufficient support force when limiting, ensuring that the hanging rod 2 can maintain stability at any angle.

[0074] Through the design of the seat plate 23 and the limiting column 24, the limiting seat 20 can directly cooperate with the insertion hole 2b of the hanging rod 2 without the need for complex mechanical structures or additional connecting parts. This simplified design not only reduces production costs, but also reduces the complexity of installation and maintenance.

[0075] In the second embodiment, please refer to Figure 4 and Figure 5 The seat plate 23 is provided with a second frictional clamping tooth 20d on the side connected with the limiting column 24.

[0076] The second frictional clamping tooth 20d is a microstructure provided on the side of the seat plate 23 connected with the limiting column 24, usually in the form of sawtooth or wave. Its main function is to cooperate with the protruding structure at the end of the hanging rod 2 to provide sufficient friction and clamping effect, so as to realize the angle limiting of the hanging rod 2. The design of the second frictional clamping tooth 20d not only needs to ensure that the hanging rod 2 can smoothly slide during rotation, but also needs to provide sufficient resistance when needed to realize accurate angle positioning.

[0077] When the hanging rod 2 rotates, the protruding structure at its end slides on the frictional clamping tooth on the seat plate 23. The design of the second frictional clamping tooth 20d makes the hanging rod 2 feel a certain resistance during rotation, which not only ensures that the hanging rod 2 can rotate flexibly, but also can provide sufficient friction to realize angle limiting when needed. The seat plate 23 provides stable support for the rotation of the hanging rod 2, ensuring smooth and reliable rotation.

[0078] The second frictional clamping tooth 20d cooperates with the protruding structure at the end of the hanging rod 2 to provide sufficient friction and clamping effect, so that the hanging rod 2 can realize accurate limiting at any angle. This design not only improves the angle adjustment accuracy of the air conditioner wind deflector, but also allows users to flexibly adjust the angle of the wind deflector according to their needs, enhancing the user experience of the product.

[0079] In the second embodiment, please refer to Figure 4 and Figure 5 The limiting column 24 includes a column body 241 and a plurality of limiting strips 242. The column body 241 is connected with one end of the seat plate 23 away from the transmission block 10. The plurality of limiting strips 242 are each connected with one end of the column body 241 away from the seat plate 23 and are arranged along the circumference of the column body 241 at intervals.

[0080] The limiting strip 242 is a key structure on the limiting column 24, with one end connected with one end of the column body 241 away from the seat plate 23 and arranged along the circumference of the column body 241 at intervals. The main function of the limiting strip 242 is to cooperate with the structure at the end of the hanging rod 2 to realize the angle limiting of the hanging rod 2. The design of the plurality of limiting strips 242 arranged at intervals usually has a certain elasticity to ensure that the hanging rod 2 can smoothly pass through the limiting strip 242 during rotation and realize stable limiting when needed.

[0081] The hanging rod 2 is connected to the limiting seat 20 by matching the insertion hole 2b at its end with the column body 241 of the limiting column 24. At this time, the structure at the end of the hanging rod 2 is aligned with the limiting strips 242, but the limiting has not yet been achieved. When the hanging rod 2 rotates, the structure at its end slides between the limiting strips 242. The design of the limiting strips 242 allows the hanging rod 2 to smoothly pass through during rotation, while providing a certain elastic buffer to reduce friction and noise during rotation.

[0082] When the hanging rod 2 is rotated to the desired angle, the structure (such as the protrusion or groove) at its end matches with the limiting strips 242, achieving angle limiting. The elastic design of the limiting strips 242 ensures that the hanging rod 2 can stably stay at any angle, while avoiding accidental rotation caused by external forces. The matching of the limiting strips 242 with the structure at the end of the hanging rod 2 not only improves the accuracy of angle adjustment, but also allows users to flexibly adjust the angle of the air conditioner wind deflector as needed, enhancing the user experience of the product.

[0083] The elastic design of the limiting strips 242 allows the hanging rod 2 to smoothly slide during rotation, while providing sufficient resistance when needed to achieve angle limiting. This design not only improves the flexibility of the hanging rod 2 during rotation, but also ensures the smoothness of the rotation process, reducing the phenomenon of jamming caused by structural interference.

[0084] In the second embodiment, please refer to Figure 4 and Figure 5 The end of each limiting strip 242 away from the column body 241 is provided with a protruding part 242a, and the protruding part 242a is located on the outer side wall of the limiting strip 242.

[0085] The protruding part 242a is a structure provided at the end of each limiting strip 242 away from the column body 241, located on the outer side wall of the limiting strip 242. The main function of the protruding part 242a is to further enhance the matching effect of the limiting strip 242 with the structure at the end of the hanging rod 2, providing additional friction and clamping points, so as to achieve more accurate angle limiting. The design of the protruding part 242a usually has a certain shape and size to ensure close matching with the structure at the end of the hanging rod 2.

[0086] The design of the protruding part 242a makes the matching of the limiting strip 242 with the structure at the end of the hanging rod 2 more closely. When the hanging rod 2 is rotated to the desired angle, the protruding part 242a will be in close contact with the protrusion or groove structure at the end of the hanging rod 2, providing additional friction and clamping points. This design not only improves the accuracy of angle limiting, but also ensures that the hanging rod 2 can stably stay at any angle, avoiding accidental rotation caused by external forces.

[0087] Although the protrusions 242a provide additional friction, their design still allows the hanging rod 2 to slide smoothly during rotation. The elastic properties of the limiting strip 242 combined with the shape design of the protrusions 242a enable the hanging rod 2 to smoothly pass through the limiting strip 242 when rotating, while achieving stable limiting when needed. This design balances the flexibility of rotation and the accuracy of limiting, ensuring that users can easily adjust the angle of the air conditioner deflector.

[0088] By providing protrusions 242a on the outer side wall of the limiting strip 242, this design does not require additional complex mechanical structures or electronic components to achieve the precise limiting function of the hanging rod 2. This simplified design not only reduces production costs, but also reduces maintenance difficulty, improving the market competitiveness of the product.

[0089] The utility model also proposes a kind of drive module, please refer to Figure 1 And Figure 3 The drive module includes drive motor 1, hanging rod 2 and the shaft coupling;One end of hanging rod 2 is provided with plug-in column 2a, and the end portion of the end of plug-in column 2a away from hanging rod 2 is provided with limiting protrusion;Plug-in column 2a is inserted in the limiting seat 20 of shaft coupling, and the specific structure of the shaft coupling is referred to the above embodiment, since the drive module adopts all technical solutions of the above first embodiment, at least has all beneficial effects brought by the technical solutions of the above embodiment, which will not be described one by one here.

[0090] Drive motor 1 is the core power source of drive module, is responsible for providing power to drive the rotation of air conditioner deflector. It usually outputs power through motor shaft, and transmits power to hanging rod 2 through shaft coupling, so as to realize the automatic adjustment function of deflector. The design of drive motor 1 needs to have high efficiency, low noise and stable output characteristics to ensure the smooth operation of air conditioner deflector.

[0091] Hanging rod 2 is the key component connecting air conditioner deflector and shaft coupling, for supporting deflector and transmitting power. One end of hanging rod 2 is provided with plug-in column 2a, and the other end is connected with air conditioner deflector. The design of hanging rod 2 needs to have enough strength and stability to bear the weight of deflector and the moment generated when rotating.

[0092] Plug-in column 2a is the structure of one end of hanging rod 2, for cooperating with limiting seat 20 of shaft coupling. The shape and size design of plug-in column 2a matches with limiting column 24 of limiting seat 20, to ensure that hanging rod 2 can be stably inserted into limiting seat 20, and maintain good connection state during rotation. The end portion of the end of plug-in column 2a away from hanging rod 2 is provided with limiting protrusion, for cooperating with limiting structure in limiting seat 20, to realize angle limiting function.

[0093] The limiting protrusion is a structure arranged at the end of the insertion column 2a, which is used to cooperate with the limiting strip 242 or the friction clamping tooth in the limiting seat 20. The design of the limiting protrusion enables the hanging rod 2 to be in close contact with the structure in the limiting seat 20 during rotation, thereby realizing accurate angle limiting. The shape and size of the limiting protrusion need to be accurately matched with the limiting strip 242 or the friction clamping tooth in the limiting seat 20 to ensure the reliability of the limiting function.

[0094] The coupling piece is a key connecting component in the driving module, which is used to transmit the power of the driving motor 1 to the wind plate body through the hanging rod 2 and realize the angle limiting function of the hanging rod 2. The coupling piece includes a transmission block 10 and a limiting seat 20, and the limiting seat 20 is provided with a column body 241 and a limiting strip 242. The column body 241 is used to cooperate with the insertion column 2a, and the limiting strip 242 is used to cooperate with the limiting protrusion to realize the angle limiting of the hanging rod 2.

[0095] When the driving motor 1 starts, the power is transmitted to the limiting seat 20 through the transmission block 10, and the column body 241 in the limiting seat 20 further transmits the power to the insertion column 2a of the hanging rod 2, thereby driving the hanging rod 2 to rotate. During rotation, the limiting protrusion at the end of the insertion column 2a slides on the limiting strip 242 or the friction clamping tooth in the limiting seat 20. The design of the limiting strip 242 or the friction clamping tooth allows the hanging rod 2 to smoothly slide during rotation, while providing certain resistance to ensure that the rotation process is smooth and reliable.

[0096] When the hanging rod 2 is rotated to the required angle, the limiting protrusion at the end of the insertion column 2a tightly cooperates with the limiting strip 242 or the friction clamping tooth in the limiting seat 20, thereby realizing angle limiting. The elastic design of the limiting strip 242 or the friction clamping tooth ensures that the hanging rod 2 can stably stay at any angle, while avoiding accidental rotation caused by external force. This limiting method not only improves the accuracy of angle adjustment, but also allows users to flexibly adjust the angle of the air conditioner wind deflector according to needs, thereby enhancing the user experience of the product.

[0097] The insertion column 2a tightly cooperates with the column body 241 in the limiting seat 20, and the limiting protrusion tightly contacts the limiting strip 242 or the friction clamping tooth, thereby ensuring that the hanging rod 2 will not loosen or fall off during rotation and limiting. This design significantly improves the overall stability of the coupling piece and prolongs the service life of the product.

[0098] The utility model also provides a driving module, please refer to Figure 4 and Figure 5The driving module includes a driving motor, a hanging rod 2, and the coupling piece; one end of the hanging rod 2 is provided with a plug-in hole 2b; the limiting seat 20 of the coupling piece is inserted into the plug-in hole 2b away from one end of the transmission block 10 of the coupling piece; the specific structure of the coupling piece is referred to the above-mentioned embodiments; since the driving module adopts all the technical solutions of the second embodiment, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0099] The driving motor is the core power source of the driving module, responsible for providing power to drive the rotation of the air conditioner wind deflector. It outputs power through the motor shaft and transmits power to the hanging rod 2 through the coupling piece, thereby realizing the automatic adjustment function of the wind deflector. The design of the driving motor needs to have high efficiency, low noise and stable output characteristics to ensure the smooth operation of the air conditioner wind deflector.

[0100] The hanging rod 2 is a key component connecting the air conditioner wind deflector and the coupling piece, used to support the wind deflector and transmit power. One end of the hanging rod 2 is provided with a plug-in hole 2b, which is used to cooperate with the limiting seat 20 of the coupling piece. The design of the hanging rod 2 needs to have enough strength and stability to withstand the weight of the wind deflector and the moment generated during rotation.

[0101] The plug-in hole 2b is a structure provided at one end of the hanging rod 2, used to cooperate with the limiting seat 20 of the coupling piece. The shape and size of the plug-in hole 2b are designed to match the column body 241 of the limiting seat 20, ensuring that the limiting seat 20 can be stably inserted and fixed inside the hanging rod 2. The design of the plug-in hole 2b not only needs to ensure the tight connection between the hanging rod 2 and the limiting seat 20, but also needs to allow the hanging rod 2 to rotate freely under the guidance of the limiting seat 20.

[0102] The coupling piece is a key connecting component in the driving module, used to transmit the power of the driving motor to the hanging rod 2 and realize the angle limiting function of the hanging rod 2. The coupling piece includes a transmission block 10 and a limiting seat 20, the transmission block 10 is connected with the shaft of the driving motor, and the limiting seat 20 is connected with one end of the transmission block 10 and inserted into the plug-in hole 2b of the hanging rod 2. The design of the limiting seat 20 needs to ensure the tight cooperation with the plug-in hole 2b and provide the angle limiting function.

[0103] The limiting seat 20 is part of the coupling piece, located at the other end of the transmission block 10. The main function of the limiting seat 20 is to cooperate with the plug-in hole 2b of the hanging rod 2 to realize the rotation and limiting function of the hanging rod 2. The column body 241 of the limiting seat 20 is inserted into the plug-in hole 2b, and the limiting strip 242 or other structures on it cooperate with the structure at the end of the hanging rod 2 to realize the angle limiting.

[0104] First, the driving motor is connected with the transmission block 10 of the shaft through the transmission block 10, ensuring that the power can be smoothly transmitted to the limiting seat 20. The insertion hole 2b of the hanging rod 2 is aligned with the column body 241 part of the limiting seat 20, and the limiting seat 20 is inserted into the insertion hole 2b. At this time, the limiting seat 20 is tightly matched with the insertion hole 2b of the hanging rod 2, but the angle limiting has not been realized. When the limiting seat 20 is completely inserted into the insertion hole 2b, the hanging rod 2 is connected with the shaft, and the power of the driving motor can be transmitted to the hanging rod 2 through the shaft, thereby driving the air conditioner wind deflector to rotate.

[0105] When the driving motor starts, the power is transmitted to the limiting seat 20 through the transmission block 10, and the column body 241 of the limiting seat 20 further transmits the power to the insertion hole 2b of the hanging rod 2, thereby driving the hanging rod 2 to rotate. In the rotating process, the column body 241 of the limiting seat 20 is tightly matched with the insertion hole 2b, ensuring that the rotation of the hanging rod 2 is stable and reliable. The limiting strip 242 or other structure in the limiting seat 20 allows the hanging rod 2 to smoothly slide during rotation, while providing certain resistance to ensure that the rotation process is stable and reliable.

[0106] When the hanging rod 2 rotates to the required angle, the limiting strip 242 or other structure in the limiting seat 20 cooperates with the structure (such as the protrusion or groove) at the end of the hanging rod 2 to realize angle limiting. The design of the limiting strip 242 or other structure ensures that the hanging rod 2 can be stably stopped at any angle, while avoiding accidental rotation caused by external force. This limiting method not only improves the accuracy of angle adjustment, but also allows users to flexibly adjust the angle of the air conditioner wind deflector according to needs, enhancing the user experience of the product.

[0107] The column body of the limiting seat 20 is tightly matched with the insertion hole of the hanging rod 2, and the design of the limiting strip or other structure allows the hanging rod 2 to smoothly slide during rotation. This design not only improves the rotation flexibility of the hanging rod 2, but also ensures the stability of the rotation process, reducing the jamming phenomenon caused by structural interference.
