[0064] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0065] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0066] In addition, if the embodiments of the present utility model involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or", "or / and", or "and / or" appear throughout the text, their meanings include three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or is unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0067] The transmission assembly is used to transmit the driving force of the driving assembly to the component to be driven. Exemplarily, for example, in an air conditioner, the air supply angle is generally adjusted by a deflector. When driving the deflector of the air conditioner, a transmission assembly needs to be provided to transmit the driving force of the driving motor to the deflector, and the transmission assembly is used to drive the deflector to move. However, currently, the overall space of the transmission assembly is large, which is not conducive to miniaturization development.

[0068] Furthermore, the existing transmission assemblies mostly adopt the structural form of a gear and rack. Exemplarily, for example, the transmission assembly may include two gear structures and one rack structure. The two gear structures can be located on both sides of the rack structure, and both gear structures can mesh with the rack structure. One of the gear structures can be the driving gear, and the other gear structure is the driven gear. The driving gear can be connected to the driving motor, and the driven gear can be connected to the component to be driven. When the transmission assembly is transmitting, the driving motor drives the driving gear to rotate, the driving gear drives the rack structure to translate, the rack structure drives the driven gear to rotate, and the driven gear drives the component to be driven to rotate. However, the gear structure and the rack structure in the existing transmission assembly are directly arranged layer by layer, and the overall space occupied is at least the size obtained by adding up the tooth diameters of the two gear structures and the thickness of one rack structure. Therefore, the overall occupied space of the existing transmission assembly is large, which is not conducive to miniaturization development.

[0069] Based on this, referring to Figures 1 to 6, an embodiment of the present utility model provides a transmission assembly, which can be applied to an air conditioner, and the rotation of the air deflector of the air conditioner can be realized through this transmission assembly. This transmission assembly can also be applied to other machines or structures that need to drive the rotation of blades. The transmission assembly includes a first gear 100, a second gear 200 and a rack 300. The first gear 100 is configured to rotate around a first axis 110, the second gear 200 is configured to rotate around a second axis 210, and the rack 300 includes a base 310 located between the first gear 100 and the second gear 200. A first concave portion 320 is provided on one side of the base 310 close to the first gear 100, and a first meshing tooth 321 meshing with the first gear 100 is provided at the bottom of the first concave portion 320. A second meshing tooth 331 meshing with the second gear 200 is provided on the side of the base 310 close to the second gear 200. Among them, the first gear 100 is used to drive the rack 300 to translate in the first direction X, so that the rack 300 drives the second gear 200 to rotate. At this time, the first gear 100 is the driving gear and the second gear 200 is the driven gear. Or, the second gear 200 is used to drive the rack 300 to translate in the first direction X, so that the rack 300 drives the first gear 100 to rotate. At this time, the first gear 100 is the driven gear and the second gear 200 is the driving gear. Exemplarily, for example, the first direction X can be horizontal and transverse.

[0070] Specifically, in this embodiment, the first gear 100 and the second gear 200 are respectively arranged on opposite sides of the base 310 of the rack 300, and a groove is formed on the base 310 to form a first concave portion 320, and the first gear 100 is arranged in the first concave portion 320, so that at least part of the first gear 100 is arranged in the first concave portion 320. Compared with the existing structure form in which the gear structure and the rack structure are directly listed layer by layer in the transmission assembly, in the transmission assembly provided in this embodiment, since at least part of the first gear 100 is arranged in the first concave portion 320, the overall space occupied by the transmission assembly provided in this embodiment is the sum of the tooth diameters of the first gear 100 and the second gear 200 and the thickness of the rack 300 minus the groove depth of the first concave portion 320, thereby reducing the size of the transmission assembly in the thickness direction and reducing the overall space occupied by the transmission assembly.

[0071] Adopting the above structure is beneficial to ensuring the stability of the transmission assembly during transmission, and is also beneficial to compressing the overall volume of the transmission assembly, reducing the space occupied by the transmission assembly, and making the machine applying this transmission assembly develop in the direction of miniaturization.

[0072] Furthermore, in this embodiment, during the transmission of the transmission assembly, the rotation of the first gear 100 is converted into the translation of the rack 300, and the translation of the rack 300 is converted into the rotation of the second gear 200. This coordinated operation mode of the transmission assembly ingeniously realizes the efficient conversion between rotation-translation-rotation, so that the transmission structure of the transmission assembly is simple, the transmission accuracy is high, and the transmission stability is good.

[0073] Further, in some embodiments, taking the application of the transmission assembly to an air conditioner and the rotation of the air guide plate of the air conditioner through the transmission assembly as an example, the first gear 100 can be connected to the drive motor 500 (for example, the first gear 100 can be connected to the drive shaft of the drive motor 500), so that the first gear 100 serves as a driving gear. The second gear 200 can be connected to the air guide plate (for example, the second gear 200 can be extended with a rotating shaft, and the air guide plate and the second gear 200 are connected by the rotating shaft), so that the second gear 200 serves as a driven gear. When the angle of the air guide plate needs to be adjusted, the drive motor 500 is started. At this time, the drive shaft of the drive motor 500 will drive the first gear 100 to rotate. Since the first gear 100 and the first meshing tooth 321 of the rack 300 are meshed and connected, the first gear 100 will drive the rack 300 to translate along the first direction X. Since the second gear 200 and the second meshing tooth 331 of the rack 300 are meshed and connected, the rack 300 will drive the second gear 200 to rotate (it should be noted that the rotation direction of the second gear 200 is opposite to that of the first gear 100). The air guide plate can be driven to rotate through the second gear 200 to achieve the angle adjustment of the air guide plate.

[0074] Further, in some embodiments, referring to Figure 4 , the first concave portion 320 can directly penetrate to the end of the base 310, which is conducive to the processing and forming of the first concave portion 320. Figure 5 and Figure 6 The first recess 320 may not directly penetrate to the end of the base 310 , but may only be partially grooved on the base 310 . This helps to reduce the groove area on the rack 300 , thereby improving the structural strength of the rack 300 .

[0075] It should be noted that the first axis 110 may be parallel to the second axis 210, in which case the first gear 100 and the second gear 200 may both be spur gears, or the first gear 100 and the second gear 200 may both be helical gears. The first axis 110 may also be non-parallel to the second axis 210, in which case at least one of the first gear 100 and the second gear 200 is a spur gear and the other is a helical gear.

[0076] In some embodiments, referenceFigures 2 to 6 , preferably, the second axis 210 is parallel to the first axis 110. At this time, both the first gear 100 and the second gear 200 can be spur gears. Setting the second axis 210 parallel to the first axis 110 is beneficial to maintaining the consistency of the rotation directions of the first gear 100 and the second gear 200, thereby facilitating the simplification of the connection structure of the transmission assembly, improving the transmission smoothness of the transmission assembly, and enabling the transmission assembly to achieve transmission more directly and efficiently.

[0077] In some embodiments, referring to Figures 2 to 6 , the first engaging teeth 321 are arranged along the first direction X, and the first direction X is perpendicular to the first axis 110. Exemplarily, for example, the first direction X can be horizontal and transverse.

[0078] Specifically, in this embodiment, the most direct vertical meshing form is adopted between the first gear 100 and the first engaging teeth 321, which can avoid unnecessary relative sliding between the first gear 100 and the first engaging teeth 321 when the first gear 100 rotates, thereby facilitating the improvement of the smoothness of the first gear 100 during transmission. In addition, adopting the most direct vertical meshing form between the first gear 100 and the first engaging teeth 321 is beneficial to improving the structural compactness between the first gear 100 and the first engaging teeth 321.

[0079] In some embodiments, referring to Figures 2 to 6 , the second engaging teeth 331 are arranged along the first direction X, and the first direction X is perpendicular to the first axis 110. Exemplarily, for example, the first direction X can be horizontal and transverse.

[0080] Specifically, in this embodiment, the most direct vertical meshing form is adopted between the second gear 200 and the second engaging teeth 331, which can avoid unnecessary relative sliding between the second gear 200 and the second engaging teeth 331 when the second gear 200 rotates, thereby facilitating the improvement of the smoothness of the second gear 200 during transmission. In addition, adopting the most direct vertical meshing form between the second gear 200 and the second engaging teeth 331 is beneficial to improving the structural compactness between the second gear 200 and the second engaging teeth 331.

[0081] In some embodiments, referring to Figures 2 to 4 , and Figure 6 , a second recess 330 is provided on one side of the base 310 close to the second gear 200, and the second engaging teeth 331 are provided at the bottom of the second recess 330.

[0082] Specifically, in this embodiment, referring to the structural relationship between the first gear 100 and the first recess 320 described above, another groove is formed on the base body 310 to form a second recess 330, and the second gear 200 is disposed in the second recess 330 such that the second gear 200 is at least partially or entirely disposed in the second recess 330. With the above structure, since the first gear 100 is disposed in the first recess 320 and at the same time the second gear 200 is disposed in the second recess 330, the volume of the first gear 100 and the second gear 200 protruding from the rack 300 can be reduced simultaneously, which is beneficial to further compressing the overall volume of the transmission component, further reducing the space occupied by the transmission component, and enabling the machine using the transmission component to develop in the direction of miniaturization.

[0083] It can be understood that since the first gear 100 and the second gear 200 are respectively disposed on opposite sides of the base body 310, and since the first recess 320 is disposed on the side of the base body 310 close to the first gear 100 and the second recess 330 is disposed on the side of the base body 310 close to the second gear 200, the first recess 320 and the second recess 330 are also located on opposite sides of the base body 310. With the above structure, while reducing the overall volume of the transmission component, the overall structural strength of the transmission component can be ensured.

[0084] Further, in some embodiments, referring to Figure 4 , the second recess 330 can directly penetrate to the end of the base body 310, which is beneficial to the processing and forming of the second recess 330. Or, referring to Figure 6 , the second recess 330 may not directly penetrate to the end of the base body 310, and only partial grooving is performed on the base body 310, which is beneficial to reducing the grooving area on the rack 300, thereby being beneficial to improving the structural strength of the rack 300.

[0085] In some embodiments, referring to Figure 4 , along the first direction X, the first recess 320 and the second recess 330 are located on opposite sides of the base body 310, and along the second direction Y, the first recess 320 and the second recess 330 at least partially do not coincide. Wherein, the second direction Y is perpendicular to the first direction X and the first axis 110. Exemplarily, for example, the first direction X may be horizontal and transverse.

[0086] Specifically, in this embodiment, along the first direction X, the first recess 320 and the second recess 330 are disposed on opposite sides of the base body 310. Exemplarily, for example, the first recess 320 can be disposed in the left half of the base body 310, and the second recess 330 can be disposed in the right half of the base body 310. With such a structure, it is beneficial to reasonably distribute the positions of the first gear 100 and the second gear 200 (because the first gear 100 is disposed in the first recess 320, the second gear 200 is disposed in the second recess 330, and the first recess 320 and the second recess 330 adopt the above distribution form, that is, the reasonable distribution of the positions of the first gear 100 and the second gear 200 is realized), realize the reasonable utilization and allocation of the base body 310 in space, and further facilitate improving the compactness of the overall structure formed by the first gear 100, the second gear 200 and the rack 300, and reducing the volume of the overall structure formed by the first gear 100, the second gear 200 and the rack 300.

[0087] Along the second direction Y, the first recess 320 and the second recess 330 at least partially do not coincide, that is, the first recess 320 and the second recess 330 are at least partially staggered on the base body 310. In this way, although two grooves are formed on the base body 310, the overall structural strength of the transmission assembly can be ensured. In other words, if the first recess 320 and the second recess 330 are coincidentally disposed along the second direction Y, the structural thickness of the base body 310 at the groove opening will become very thin. With the continuous wear between the first gear 100 and the first engaging tooth 321, and the continuous wear between the second gear 200 and the second engaging tooth 331, the structure of the base body 310 at the groove opening is easily worn out, thereby shortening the service life of the transmission assembly, indirectly wasting material resources, and increasing the maintenance and replacement costs of the transmission assembly.

[0088] In some embodiments, referring to Figure 4 , along the first direction X, the first recess 320 penetrates through one end of the base body 310, and the second recess 330 penetrates through the other end of the base body 310. With such a structure, it is beneficial to process and form the first recess 320 and the second recess 330.

[0089] In some embodiments, referring to Figure 4 , along the first direction X, the first recess 320 and the second recess 330 at least partially coincide, and the first engaging tooth 321 is located on the side of the second engaging tooth 331 close to the second gear 200. For example, the first engaging tooth 321 and the second engaging tooth 331 can be oppositely disposed. Exemplarily, for example, the first direction X can be horizontal and transverse.

[0090] Specifically, in this embodiment, along the first direction X, the coincidence of the first recess 320 and the second recess 330 means that the slot depths of the first recess 320 and the second recess 330 are the same. With such a structure, it is beneficial to improve the structural symmetry of the transmission assembly, make the self-gravity of the transmission assembly more balanced, thereby improving the seismic resistance of the transmission assembly during transmission and ensuring the stability of the transmission assembly during transmission.

[0091] Further, in this embodiment, the first engaging tooth 321 and the second engaging tooth 331 are arranged oppositely, that is, the slotting directions of the first recess 320 and the second recess 330 are opposite (because the first engaging tooth 321 is arranged at the bottom of the first recess 320, and the second engaging tooth 331 is arranged at the bottom of the second recess 330. If the first engaging tooth 321 and the second engaging tooth 331 are arranged oppositely, then the bottoms of the first recess 320 and the second recess 330 are arranged oppositely, that is, the slotting directions of the first recess 320 and the second recess 330 are opposite). This is beneficial to installing the first gear 100 and the second gear 200 in opposite directions. Exemplarily, for example, if the first gear 100 is installed above the rack 300, then the second gear 200 will be installed below the rack 300, so that the first gear 100 and the second gear 200 are respectively located on opposite sides of the rack 300. With such a structure, it is beneficial to reasonably arrange the positions of the first gear 100 and the second gear 200 in space, making the structure of the transmission assembly more compact.

[0092] In addition, when the first gear 100 and the second gear 200 are arranged on opposite sides of the rack 300, during the transmission of the transmission assembly, the rotation directions of the first gear 100 and the second gear 200 are opposite, which is beneficial to improving the transmission sensitivity and transmission accuracy of the transmission assembly and avoiding gear slippage of the transmission assembly.

[0093] In some embodiments, referring to Figures 2 to 6 , the pitch diameter of the first gear 100 is larger than that of the second gear 200. Among them, the first gear 100 with a larger pitch diameter can be connected to the drive shaft of the drive motor 500 and serve as the driving gear in this transmission assembly. The second gear 200 with a smaller pitch diameter can be connected to a rotating blade such as a guide vane and serve as the driven gear in this transmission assembly.

[0094] Specifically, in this embodiment, the first gear 100 with a larger tooth diameter can provide a larger rotational output compared to the second gear 200 with a smaller tooth diameter. The first gear 100 with a larger tooth diameter is used as the driving gear of this transmission assembly, enabling this transmission assembly to generate a larger mechanical output under the same power input conditions, thus making it easier to drive the second gear 200 to rotate through the first gear 100, realizing the transmission conversion between the first gear 100, the rack 300, and the second gear 200, and achieving the purpose of reducing energy consumption. In addition, the first gear 100 with a larger tooth diameter can usually provide a larger torque at a lower rotational speed, which is beneficial to reducing the mechanical wear between the gear and the rack 300 caused by high-speed operation, extending the service life of the transmission assembly, and realizing a smoother and more stable operation of the transmission assembly.

[0095] By adjusting the tooth diameters of the first gear 100 and the second gear 200 in this transmission assembly, the size of this transmission assembly can be optimized, making this transmission assembly more compact and delicate, so that this transmission assembly can be applied to a working environment with limited space.

[0096] In some embodiments, referring to Figure 4 and Figure 6 , the tooth diameter of the second gear 200 is not greater than the groove depth of the second recess 330.

[0097] Specifically, referring to the above embodiment, the second gear 200 is used as the driven gear in this transmission assembly. The tooth diameter of the second gear 200 can be designed to be smaller. The tooth diameter of the second gear 200 can be designed to be smaller than the groove depth of the second recess 330, or the tooth diameter of the second gear 200 can be designed to be the same as the groove depth of the second recess 330. The second gear 200 can be completely hidden in the second recess 330, so that the second gear 200 does not protrude from the second recess 330, thereby eliminating the influence of the second gear 200 on the overall structure size of the transmission assembly, which is beneficial to reducing the overall volume of the transmission assembly.

[0098] In some embodiments, referring to Figures 2 to 6 , along the direction parallel to the first axis 110, the first gear 100 is extended with an input shaft 120, and the second gear 200 is extended with an output shaft 220. Among them, along the direction parallel to the first axis 110, the input shaft 120 and the output shaft 220 are arranged on the same side of the rack 300.

[0099] Specifically, in this embodiment, the first gear 100 can be connected to the driving motor 500. Exemplarily, for example, the driving shaft of the driving motor 500 can be connected to the input shaft 120, so that the driving motor 500 and the first gear 100 are connected to realize the driving of the first gear 100 by the driving motor 500. Among them, the driving shaft and the input shaft 120 can be connected by a coupling. The second gear 200 can be connected to a rotating vane structure such as a guide vane. Exemplarily, for example, a rotating vane structure such as a guide vane can be connected to the output shaft 220 to realize the driving of the rotating vane structure such as the guide vane by the second gear 200.

[0100] Further, in some embodiments, when it is necessary to rotate the rotating vane structure such as the guide vane, the driving motor 500 is started. At this time, the driving shaft of the driving motor 500 will drive the first gear 100 to rotate. Since the first gear 100 is meshed with the first engaging tooth 321 of the rack 300, the first gear 100 will drive the rack 300 to translate along the first direction X. And since the second gear 200 is meshed with the second engaging tooth 331 of the rack 300, the rack 300 will drive the second gear 200 to rotate. Through the second gear 200, the rotating vane structure such as the guide vane can be driven to rotate, realizing the angle adjustment of the rotating vane structure such as the guide vane.

[0101] Further, in this embodiment, the input shaft 120 and the output shaft 220 are arranged on the same side of the rack 300, which can simplify the turnover link of the transmission component during power transmission, make the power transmission more direct, and effectively reduce the energy loss. With the above structure, not only the structural complexity of the transmission component in the spatial layout is reduced, but also the stability and transmission efficiency of the transmission component during operation are greatly improved.

[0102] In some embodiments, referring to Figures 1 to 3 , the transmission component includes a box body 400. An accommodation cavity 430 is arranged in the box body 400. The first gear 100, the second gear 200 and the rack 300 are all arranged in the accommodation cavity 430. Along the direction parallel to the first axis 110, the first gear 100 extends and is provided with an input shaft 120, and the second gear 200 extends and is provided with an output shaft 220. Among them, the box body 400 is provided with a first through hole 440 and a second through hole 450. The input shaft 120 passes through the first through hole 440 and extends out of the accommodation cavity 430, and the output shaft 220 passes through the second through hole 450 and extends out of the accommodation cavity 430.

[0103] Specifically, in this embodiment, the first gear 100, the second gear 200, and the rack 300 are all arranged in the accommodation cavity 430 of the box body 400, which is beneficial to structurally protect the first gear 100, the second gear 200, and the rack 300, preventing foreign objects from getting stuck between the first gear 100 and the rack 300, or between the second gear 200 and the rack 300, resulting in insensitive power transmission of the transmission assembly and inflexible rotation of the rotating blade structures such as the air deflector.

[0104] Further, in this embodiment, a first through hole 440 is provided on the box body 400, and the input shaft 120 passes through the first through hole 440 and extends out of the accommodation cavity 430 for connection with the drive shaft, thereby realizing the connection between the first gear 100 and the drive motor 500. A second through hole 450 is provided on the box body 400, and the output shaft 220 passes through the second through hole 450 and extends out of the accommodation cavity 430 for connection with the rotating blade structures such as the air deflector, thereby realizing the connection between the second gear 200 and the rotating blade structures such as the air deflector.

[0105] Further, in some embodiments, threaded holes may be provided on the box body 400 and the drive motor 500, and the drive motor 500 can be connected to the outside of the box body 400 through screw structures passing through the threaded holes.

[0106] Further, in some embodiments, the box body 400 may be a detachable structure. Exemplarily, for example, referring to Figure 2 and Figure 3 , the box body 400 may include a first housing 410 and a second housing 420. The accommodation cavity 430 is formed when the first housing 410 and the second housing 420 are buckled. Threaded holes may be provided on the first housing 410 and the second housing 420, and the first housing 410 and the second housing 420 can be connected together through screw structures passing through the threaded holes to form the box body 400.

[0107] Designing the box body 400 as a detachable structure is beneficial for installing the first gear 100, the second gear 200, and the rack 300 in the accommodation cavity 430, or for repairing and replacing the first gear 100, the second gear 200, and the rack 300 in the accommodation cavity 430.

[0108] In some embodiments, referring to Figure 2 and Figure 3, along the first direction X, a first baffle 322 is provided on the side of the first recess 320. Along the second direction Y, the first baffle 322 protrudes from the first engaging tooth 321. Along the first direction X, a second baffle 332 is provided on the side of the second recess 330. Along the second direction Y, the second baffle 332 protrudes from the second engaging tooth 331. Wherein, the second direction Y is perpendicular to the first direction X and the first axis 110. Exemplarily, for example, the first direction X can be horizontal and transverse.

[0109] Specifically, in this embodiment, by providing the first baffle 322, it is possible to prevent the first gear 100 from falling off the first engaging tooth 321. When the moving path of the first gear 100 deviates from the first engaging tooth 321, the first baffle 322 can prevent the first gear 100 from continuing to deviate.

[0110] Similarly, by providing the second baffle 332, it is possible to prevent the second gear 200 from falling off the second engaging tooth 331. When the moving path of the second gear 200 deviates from the second engaging tooth 331, the second baffle 332 can prevent the second gear 200 from continuing to deviate.

The driving motor 500 is connected to the first gear 100 of the transmission assembly for driving the first gear 100 to rotate around the first axis 110. The air deflector is connected to the second gear 200 of the transmission assembly and is driven by the second gear 200.

[0112] Specifically, in this embodiment, for the air deflector mechanism applying the above transmission assembly, while ensuring that the air deflector can rotate stably, it can simplify the internal structure of the air deflector mechanism, making the air deflector mechanism develop towards miniaturization.

[0113] Correspondingly, another embodiment of the present utility model further provides an indoor unit, which includes the air deflector mechanism in the above embodiment. The indoor unit further includes a housing and a heat exchanger. The housing has an air outlet. The heat exchanger is disposed inside the housing.
