When the door of the air conditioner is subjected to an impact force, the output gear and the anti-slip gear can rotate relative to each other with slipping, thereby avoiding the influence of the impact force on the driving motor and effectively protecting the driving motor.

[0004] An air conditioner according to an embodiment of the present invention includes: an air conditioner body including a blowing component and a heat exchange component, and having a front air outlet area on the air conditioner body; a door component provided outside the air conditioner body and including a door and a driving rack, the door being slidable up and down relative to the air conditioner body to open and close the front air outlet area, the driving rack being provided inside the door and extending in the up and down direction; and a driving component including a driving mechanism, the driving mechanism including a driving motor, a driving gear assembly and a transmission gear assembly, the driving gear assembly including an input gear driven by the driving motor to rotate, the transmission gear assembly including an anti-slip gear and an output gear, the anti-slip gear being meshed with the input gear for transmission, the output gear being cooperated with the anti-slip gear through an anti-slip structure to rotate synchronously in a non-slip state, and the output gear being meshed with the driving rack for transmission.

[0005] In the air conditioner according to the present invention, since the driving component includes a driving gear assembly and a transmission gear assembly, the requirement of the transmission ratio can be met to ensure the running speed of the door. Moreover, since the output gear and the anti-slip gear are cooperated through an anti-slip structure, when the door is subjected to an instantaneous impact force, the output gear and the anti-slip gear can rotate relative to each other with slipping, thereby avoiding the influence of the impact force on the driving motor and effectively protecting the driving motor.

[0006] In some embodiments, the diameter of the output gear is larger than the diameter of the anti-slip gear.

[0079] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0080] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0081] Next, with reference to the drawings, a vibration damping gear assembly 32a according to an embodiment of the first aspect of the present invention will be described.

[0082] As Figure 1 and Figure 2As shown in the figure, the vibration damping gear assembly 32a according to the embodiment of the first aspect of the present invention may include: a vibration damping gear 321, a drive shaft core 322, and a vibration damping bushing 323. The vibration damping gear 321 has a central hole 3211, and the drive shaft core 322 is disposed through the central hole 3211 (that is, at least a part of the drive shaft core 322 is located in the central hole 3211). The vibration damping bushing 323 includes a bushing portion 3231, a first end face portion 3232, and a second end face portion 3233. The bushing portion 3231 is sleeved on the drive shaft core 322 and is disposed through the central hole 3211 (that is, the bushing portion 3231 is sleeved outside at least a part of the drive shaft core 322, and at least a part of the bushing portion 3231 is located in the central hole 3211), and the drive shaft core 322 transmits torque to the vibration damping gear 321 through the vibration damping bushing 323. That is, when the drive shaft core 322 rotates, it can drive the vibration damping bushing 323 to rotate synchronously, and when the vibration damping bushing 323 rotates, it can drive the vibration damping gear 321 to rotate synchronously. The first end face portion 3232 and the second end face portion 3233 are connected to the axial two ends of the bushing portion 3231 and are respectively located outside the axial two side end faces of the hub portion 3210 of the vibration damping gear 321.

[0083] That is to say, the bushing portion 3231 in the vibration damping bushing 323 is sleeved outside the drive shaft core 322, and the vibration damping gear 321 is sleeved outside the bushing portion 3231. In other words, the bushing portion 3231 is disposed between the vibration damping gear 321 and the drive shaft core 322, so that the bushing portion 3231 can be used to transmit torque to the vibration damping gear 321 and achieve radial vibration damping of the vibration damping gear 321. At the same time, the first end face portion 3232 and the second end face portion 3233 in the vibration damping bushing 323 are respectively located outside the axial two side end faces of the hub portion 3210 of the vibration damping gear 321, so that the first end face portion 3232 and the second end face portion 3233 can be used to realize the fixed installation of the vibration damping gear 321 and the vibration damping bushing 323 and achieve axial vibration damping of the vibration damping gear 321.

[0084] For example, when the drive shaft core 322 transmits torque to the vibration damping gear 321 through the vibration damping bushing 323, vibration may occur. At this time, the radial vibration relative to the drive shaft core 322 is first transmitted from the drive shaft core 322 to the bushing portion 3231 and then to the vibration damping gear 321 (or all is absorbed by the bushing portion 3231 and is no longer transmitted to the vibration damping gear 321). The axial vibration relative to the drive shaft core 322 is first transmitted from the drive shaft core 322 to the first end face portion 3232 and the second end face portion 3424 and then to the vibration damping gear 321 (or all is absorbed by the bushing portion 3231 and is no longer transmitted to the vibration damping gear 321). Thus, the vibration transmitted from the drive shaft core 322 to the vibration damping gear 321 can be reduced, so that the problem of damage to the vibration damping gear 321 caused by excessive vibration can be reduced, and further the service life of the vibration damping gear 321 can be improved.

[0085] Meanwhile, the damping gear 321 may also generate a certain amount of vibration during operation. This part of the vibration will first be transmitted to the damping bushing 323, and then, after being damped by the damping bushing 323, it will be transmitted to the drive shaft core 322 (or all absorbed by the bushing portion 3231 and no longer transmitted to the drive shaft core 322), thereby reducing the possibility of damage to the drive shaft core 322 when it is subjected to large vibrations, and further extending the service life of the drive shaft core 322.

[0086] In short, for the damping gear assembly 32a according to the embodiment of the first aspect of the present invention, by providing a damping bushing 323 between the drive shaft core 322 and the damping gear 321 to improve vibration, the drive shaft core 322 and the damping gear 321 do not directly transmit vibration, thereby reducing the damage problems of the damping gear 321 and the drive shaft core 322 caused by excessive vibration, and further extending the service life of the damping gear assembly 32a to a certain extent. In addition, since vibration is accompanied by noise generation, while using the damping bushing 323 to damp vibration, noise reduction can also be achieved.

[0087] In some embodiments, as Figure 2 shown, the drive shaft core 322 may include a baffle portion 3221. The baffle portion 3221 abuts against the side of the first end face portion 3232 away from the damping gear 321, so that the baffle portion 3221 and the damping gear 321 are isolated by the first end face portion 3232. Thus, by providing the baffle portion 3221, the relative axial position of the drive shaft core 322 and the damping gear 321 can be simply and effectively limited, preventing the drive shaft core 322 from disengaging from the damping gear 321 along the direction from the baffle portion 3221 to the first end face portion 3232, thereby simply and effectively improving the connection reliability between the drive shaft core 322 and the damping gear 321.

[0088] In addition, as described above, by providing the first end face portion 3232, the baffle portion 3221 and the damping gear 321 do not directly contact. A part of the vibration transmitted by the drive shaft core 322 can first be transmitted from the baffle portion 3221 to the first end face portion 3232 and absorbed by the first end face portion 3232, and then transmitted to the damping gear 321 (or all absorbed by the first end face portion 3232 and no longer transmitted to the damping gear 321). Therefore, after the damping effect of the first end face portion 3232, the vibration transmitted to the damping gear 321 can be reduced, thereby reducing the damage risk of the damping gear 321, and further extending the service life of the damping gear assembly 32a to a certain extent.

[0089] In some embodiments, as Figure 2 shown, the damping gear assembly 32a may further include: a fixed end cover 324, combined Figure 3As shown, the fixed end cap 324 may include a connecting portion 3241 and a stopping portion 3242. The connecting portion 3241 passes through the damping bushing 323 (i.e., at least a part of the connecting portion 3241 penetrates into the damping bushing 323) and is connected to the drive shaft core 322. The stopping portion 3242 stops on the side of the second end face portion 3233 away from the damping gear 321, so that the stopping portion 3242 and the damping gear 321 are isolated by the second end face portion 3233. Thus, the fixed end cap 324 can be used to simply and effectively limit the relative axial position between the drive shaft core 322 and the damping gear 321, prevent the drive shaft core 322 from disengaging from the damping gear 321 along the direction from the stopping portion 3242 to the second end face portion 3233, thereby simply and effectively improving the connection reliability between the drive shaft core 322 and the damping gear 321, and making the assembly of the damping gear assembly 32a convenient and efficient.

[0090] In addition, since the second end face portion 3233 is located between the stopping portion 3242 and the damping gear 321, at this time, the stopping portion 3242 and the damping gear 321 do not directly contact. A part of the vibration transmitted by the drive shaft core 322 can be transmitted to the stopping portion 3242 first, then transmitted from the stopping portion 3242 to the second end face portion 3233, and then transmitted to the damping gear 321 (or all absorbed by the second end face portion 3233 and no longer transmitted to the damping gear 321). Therefore, after the damping effect of the second end face portion 3233, the vibration transmitted to the damping gear 321 can be reduced, thereby reducing the risk of damage to the damping gear 321, and further improving the service life of the damping gear assembly 32a to a certain extent.

[0091] In some embodiments, as Figure 3 and Figure 4 shown, the drive shaft core 322 has a plurality of clamping portions 3222 spaced apart circumferentially along the drive shaft core 322. The connecting portion 3241 includes elastic buckling positions 32411. The plurality of elastic buckling positions 32411 respectively correspond to (i.e., one-to-one correspondence) and cooperate with the plurality of clamping portions 3222, so that the fixed end cap 324 is connected to the drive shaft core 322. Thus, the structure when the drive shaft core 322 is connected to the fixed end cap 324 is simple, convenient for processing, and convenient for connection. However, the present invention is not limited thereto. For example, the plurality of elastic buckling positions 32411 can also be provided on the drive shaft core 322, and the plurality of clamping portions 3222 can be provided on the fixed end cap 324, etc., which are not limited herein.

[0092] In some embodiments, as Figure 3 and Figure 4As shown, there are two elastic buckling positions 32411, which are symmetrically arranged about the central axis of the damping gear 321. This makes the forces on the two elastic buckling positions 32411 uniform and not easily damaged. It should be noted that the structural form of the elastic buckling position 32411 is not limited. For example, it can be a hook structure, etc., so that the structure is simple and easy to process. Correspondingly, the structural form of the clamping position 3222 is not limited. For example, it can be a slot structure, a clamping block structure, etc.

[0093] In some embodiments, the damping bushing 323 can be an integral flexible part, so that the structure of the damping bushing 323 is simple and easy to process, the assembly of the damping bushing 323 and the damping gear 321 is relatively convenient, and at the same time, the damping effect of the damping bushing 323 can be improved. It should be noted that the manufacturing material of the damping bushing 323 is not limited. For example, it can be a rubber part, a plastic part, etc., as long as it can reduce the vibration transmitted between the drive shaft core 322 and the damping gear 321. There is no limit and no further elaboration here.

[0094] In some embodiments, as Figure 3 and Figure 4 shown, both the outer peripheral surface and the inner peripheral surface of the bushing part 3231 are prismatic peripheral surfaces, and the wall thickness of the bushing part 3231 is uniform. Thus, the structural strength of the bushing part 3231 is good and the force is uniform, which can improve the working reliability when the drive shaft core 322 transmits torque to the damping gear 321 through the damping bushing 323. At the same time, since the wall thickness of the bushing part 3231 is uniform, the center of gravity of the bushing part 3231 will not shift during rotation, so as to ensure the stability of the damping gear assembly 32a during operation.

[0095] In some embodiments, as Figure 2 shown, the drive shaft core 322 has a central shaft hole 3223, and the central shaft hole 3223 is adapted to cooperate with the motor shaft 311 of the drive motor 31 to transmit torque. That is to say, when the drive motor 31 works, the motor shaft 311 will rotate and drive the drive shaft core 322 to rotate synchronously, so that the drive shaft core 322 drives the damping gear assembly 32a to rotate together with the motor shaft 311.

[0096] It should be noted that the type of the drive motor 31 is not limited, and the outer dimension of the motor shaft 311 includes but is not limited to a prismatic shape, as long as the connection reliability and working reliability when the motor shaft 311 cooperates with the drive shaft core 322 are not affected. There is no further elaboration here.

[0097] Next, with reference to the drawings, the anti-slip gear assembly 33a according to the second aspect embodiment of the present invention will be described.

[0098] As Figure 5As shown, the anti-slip gear assembly 33a according to the embodiment of the second aspect of the present invention may include: a first gear 331a and a second gear 332a. The first gear 331a has a first ring portion 3311. The outer ring of the first ring portion 3311 has a first mating portion 3312, and an elastic buckle 3314 is provided on the first mating portion 3312.

[0099] As Figure 6 shown, the second gear 332a has a second ring portion 3321. Combining Figure 7 , the second ring portion 3321 is sleeved outside the first mating portion 3312. The center of the inner ring cavity of the second ring portion 3321 has a cylindrical surface boss 3322, that is, a boss whose outer peripheral surface is a cylindrical surface. The cylindrical surface boss 3322 is rotatably inserted into the first ring portion 3311, that is, at least a part of the cylindrical surface boss 3322 is inserted into the first ring portion 3311 and can rotate in the first ring portion 3311. A plurality of positioning grooves 3325 are provided on the inner peripheral wall of the second ring portion 3321 and are circumferentially spaced apart along the second ring portion 3321. The elastic buckle 3314 is adapted to cooperate with any one of the positioning grooves 3325. When the elastic buckle 3314 cooperates with the positioning groove 3325, the first gear 331a and the second gear 332a rotate synchronously.

[0100] For example, when the anti-slip gear assembly 33a works, the first gear 331a and the second gear 332a transmit torque through the cooperation of the elastic buckle 3314 and the positioning groove 3325, so that the first gear 331a and the second gear 332a can rotate synchronously. However, when one of the first gear 331a and the second gear 332a is subjected to a large resistance, or the first gear 331a or the second gear 332a suddenly rotates or suddenly stops, since the elastic buckle 3314 can undergo elastic deformation, the elastic buckle 3314 slides out of the positioning groove 3325 with which it cooperates and enters an adjacent or spaced positioning groove 3325 (depending on the magnitude of the impact force), that is, the first gear 331a and the second gear 332a slip. In other words, at this time, a relative movement will occur between the first gear 331a and the second gear 332a until the first gear 331a and the second gear 332a no longer slip, and the first gear 331a and the second gear 332a can resume synchronous rotation.

[0101] It can be understood that the rotational force output by the driving motor 31 is less than the force for the elastic buckle 3314 to deform. Thus, after the impact force decreases or disappears, the first gear 331a and the second gear 332a can rotate synchronously to meet the requirement of synchronous rotation of the first gear 331a and the second gear 332a in a non-slip state.

[0102] Moreover, by setting the cooperation between the cylindrical surface boss 3322 and the first ring portion 3311, it is possible to prevent the rotation center of the cylindrical surface boss 3322 and the first ring portion 3311 from shifting randomly, thereby avoiding the deformation problem of the first engaging portion 3312 due to the shift. Furthermore, it can ensure the reliable cooperation between the elastic buckle 3314 and the positioning groove 3325, thus guaranteeing the reliability of power transmission. Moreover, by setting the cylindrical surface boss 3322, the structural strength of the second gear 332a having the positioning groove 3325 can be improved, thereby increasing the service life of the anti-slip gear assembly 33a. In addition, in the case of slipping, by setting the cooperation between the cylindrical surface boss 3322 and the first ring portion 3311, it can be ensured that the first gear 331a and the second gear 332a can rotate relative to each other more stably, enabling the elastic buckle 3314 to cooperate with other positioning grooves 3325.

[0103] In some embodiments, as Figure 5 and Figure 6 shown, the first gear 331a may have a central shaft cylinder 3310, and the second gear 332a has a central rotating shaft 3320. At least a part of the central rotating shaft 3320 extends from the center of the cylindrical surface boss 3322 towards the first gear 331a and is rotatably inserted into the central shaft cylinder 3310. Thus, when slipping occurs between the first gear 331a and the second gear 332a, through the cooperation of the central rotating shaft 3320 and the central shaft cylinder 3310, it can be further ensured that the first gear 331a and the second gear 332a can rotate relative to each other more stably, enabling the elastic buckle 3314 to smoothly cooperate with other positioning grooves 3325, thereby improving the working reliability of the anti-slip gear assembly 33a and further increasing the structural strength of the first gear 331a and the second gear 332a, thus increasing the service life of the anti-slip gear assembly 33a.

[0104] In some embodiments, as Figure 5 and Figure 6 shown, the cylindrical surface boss 3322 may include a cylindrical ring 3323 and connecting ribs 3324. The central rotating shaft 3320 passes through the cylindrical ring 3323, and the connecting ribs 3324 connect the cylindrical ring 3323 and the central rotating shaft 3320. The connecting ribs 3324 are multiple and are spaced apart circumferentially along the central rotating shaft 3320. The end face of the central shaft cylinder 3310 facing the second gear 332a rotatably abuts against the connecting ribs 3324 to define the relative axial position of the first gear 331a and the second gear 332a.

[0105] Thus, the contact area of the first gear 331a and the second gear 332a for axial positioning can be reduced, so that the frictional force when the first gear 331a and the second gear 332a slip can be reduced, ensuring that the first gear 331a and the second gear 332a can slip smoothly, and the wear when the first gear 331a and the second gear 332a slip can also be reduced. For example, axial positioning by using the end face of the first engaging portion 3312 facing the second gear 332a can be avoided, so that the end face of the first engaging portion 3312 can be in clearance fit with the position opposite to the second gear 332a, avoiding large friction and wear of the first engaging portion 3312 during the slipping process at this position.

[0106] In some embodiments, as Figure 5 and Figure 6 shown, the central shaft cylinder 3310 and the first ring portion 3311 can be connected by support ribs 3317. There are multiple support ribs 3317 and they are spaced apart circumferentially along the central shaft cylinder 3310. Thus, the weight of the first gear 331a can be reduced to a certain extent and its structural strength can be ensured.

[0107] In some embodiments, as Figure 5 and Figure 6 shown, the first engaging portion 3312 can have a first weight-reducing hole 3313, so that the weight of the first gear 331a can be reduced to a certain extent, the material used for the first gear 331a can be reduced, and further the production cost of the first gear 331a can be reduced.

[0108] In some embodiments, as Figure 5 and Figure 6 shown, there are two first engaging portions 3312 and they are symmetrically arranged about the center of the first ring portion 3311. Each first engaging portion 3312 has elastic buckles 3314 at both ends in the circumferential direction of the first ring portion 3311. The outer ring of the first ring portion 3311 also has two second engaging portions 3315 symmetrically arranged about the center of the first ring portion 3311. The two second engaging portions 3315 and the two first engaging portions 3312 are arranged alternately, that is, there is a first engaging portion 3312 between the two second engaging portions 3315, and there is a second engaging portion 3315 between the two first engaging portions 3312. The outer surface (referring to the circumferential surface) of the second engaging portion 3315 and the outer surface (referring to the circumferential surface) of the first engaging portion 3312 are located on the same cylindrical surface, for example, a cylindrical surface coaxial with the first ring portion 3311, and the arc length of the outer surface of the second engaging portion 3315 is greater than or equal to one-third of the arc length of the outer surface of the first engaging portion 3312.

[0109] As a result, the positions of the elastic clasps 3314 can be evenly distributed or relatively evenly distributed, so that when the first gear 331a and the second gear 332a rotate synchronously, the elastic clasps 3314 are evenly stressed and not easily damaged. Moreover, in the case where the first gear 331a and the second gear 332a slip, the inner peripheral surface of the second ring portion 3321 can be supported by the first engaging portion 3312 and the second engaging portion 3315, so that the first gear 331a and the second gear 332a can rotate relative to each other relatively stably, and further the elastic clasps 3314 can cooperate smoothly with other positioning grooves 3325.

[0110] In some embodiments, as Figure 5 and Figure 6 shown, the first engaging portion 3312 may have a first weight-reducing hole 3313, and the second engaging portion 3315 has a second weight-reducing hole 3316. As a result, the structure of the first gear 331a is relatively regular, which facilitates the machining of the first gear 331a. Moreover, the first gear 331a can be evenly stressed during operation and is not easily damaged.

[0111] For example, in some specific examples, the size of the second weight-reducing hole 3316 may be the same as or substantially the same as that of the first weight-reducing hole 3313, and they are evenly distributed along the circumferential direction of the first ring portion 3311. As a result, the structure of the first gear 331a is relatively regular, which facilitates the machining of the first gear 331a. Moreover, the first gear 331a can be evenly stressed during operation and is not easily damaged.

[0112] In some embodiments, as Figure 5 and Figure 6 shown, in the axial direction of the second gear 332a, the second ring portion 3321 is located on the side closer to the first gear 331a of the tooth portion 332a1 of the second gear 332a. As a result, the axial dimension of the tooth portion 332a1 of the second gear 332a can be reduced, thereby reducing the production cost of the second gear 332a.

[0113] Next, with reference to the accompanying drawings, the driving component 300 according to the third aspect embodiment of the present invention will be described.

[0114] As Figure 8 and Figure 9 shown, the driving component 300 according to the third aspect embodiment of the present invention may include: a box body assembly 35, a rotating gear 320, and a vibration damping component 34.

[0115] As Figure 10 and Figure 11As shown, the box body assembly 35 may have a support hole 353 and a first limiting structure 354a. The rotating gear 320 is disposed within the box body assembly 35, and the rotating gear 320 may have a support shaft 3201 and a second limiting structure 3202a. The support shaft 3201 passes through the support hole 353. In the axial direction of the rotating gear 320, the first limiting structure 354a and the second limiting structure 3202a stop at both axial sides (the same as the axial direction of the rotating gear 320) of the damping assembly 34. The damping assembly 34 passes through the support hole 353 and is sleeved on the support shaft 3201, so that the support shaft 3201 can rotate relative to the support hole 353.

[0116] Thus, the damping assembly 34 is sleeved on the support shaft 3201 and is located on the shaft between the box body assembly 35 and the support shaft 3201, so that the vibration transmitted by the rotating gear 320 can be transmitted to the damping assembly 34 through the support shaft 3201, and will be transmitted to the box body assembly 35 only after being damped by the damping assembly 34, or all absorbed by the damping assembly 34, thereby making the vibration and noise generated when the driving component 300 works relatively small. At the same time, the vibration of the box body assembly 35 can be first transmitted to the damping assembly 34, and after being damped by the damping assembly 34, it is then transmitted to the rotating gear 320 provided in the box body assembly 35, or all absorbed by the damping assembly 34, thereby reducing the risk of damage to the rotating gear 320 caused by excessive vibration, and further extending the service life of the driving component 300 to a certain extent.

[0117] For the driving component 300 according to the third aspect embodiment of the present invention, by providing the damping assembly 34 between the support shaft 3201 and the box body assembly 35, the damping assembly 34 is used to reduce the internal and external vibrations of the box body assembly 35, thereby making the vibration and noise generated when the driving component 300 works relatively small. At the same time, it can also reduce the risk of damage to the rotating gear 320 caused by vibration, and further extend the service life of the driving component 300 to a certain extent.

[0118] In some embodiments, as Figure 11 and Figure 12 shown, the damping assembly 34 may include: a hollow shaft 341 and a damping sleeve 342. The hollow shaft 341 is sleeved on the support shaft 3201 and is stopped by the second limiting structure 3202a. The damping sleeve 342 passes through the support hole 353 and is stopped by the first limiting structure 354a. The damping sleeve 342 is sleeved on the hollow shaft 341 and is matched with the hollow shaft 341 through an axial limiting structure 340 to limit the movement of the damping sleeve 342 relative to the hollow shaft 341 in the axial direction of the rotating gear 320 toward the direction close to the rotating gear 320.

[0119] That is to say, when the vibration damping assembly 34 is assembled onto the support shaft 3201, the hollow shaft 341 is sleeved on the support shaft 3201, and the first limiting structure 354a on the support shaft 3201 stops the hollow shaft 341. The vibration damping sleeve 342 is sleeved outside the hollow shaft 341, and the hollow shaft 341 and the vibration damping sleeve 342 are axially cooperatively limited through the axial limiting structure 340. The first limiting structure 354a on the box body assembly 35 stops the vibration damping sleeve 342 to compress the vibration damping assembly 34, so that the vibration damping assembly 34 cannot move towards the direction close to the rotating gear 320, nor can it come off in the direction away from the rotating gear 320. Thus, the installation and fixation of the vibration damping assembly 34 can be achieved.

[0120] Thus, by setting the hollow shaft 341 to be sleeved on the support shaft 3201, the friction between the vibration damping assembly 34 and the rotating gear 320 can be reduced, thereby ensuring the working reliability of the rotating gear 320. Moreover, the vibration damping sleeve 342 will not affect the rotation of the support shaft 3201, and can effectively play the roles of vibration damping and installation. It should be noted that the production material of the vibration damping sleeve 342 includes but is not limited to rubber parts, which will not be elaborated here.

[0121] In some embodiments, as Figure 11 shown, the axial limiting structure 340 can also be set to be able to limit the vibration damping sleeve 342 from moving in the direction away from the rotating gear 320 along the axial direction of the rotating gear 320 relative to the hollow shaft 341. That is to say, through the axial limiting structure 340, the vibration damping sleeve 342 cannot move towards the direction close to the rotating gear 320, and the vibration damping sleeve 342 cannot move in the direction away from the rotating gear 320. Thus, by setting the axial limiting structure 340, the vibration damping sleeve 342 and the hollow shaft 341 can be axially relatively fixed. And since the vibration damping sleeve 342 is sleeved outside the hollow shaft 341, the vibration damping sleeve 342 and the hollow shaft 341 are pre-fixed components and can be installed and disassembled together, thereby reducing the assembly difficulty of installing the vibration damping assembly 34 onto the rotating gear 320. Moreover, the structure of the vibration damping assembly 34 can be made compact, thereby further improving the working reliability of the vibration damping assembly 34.

[0122] In some embodiments, as Figure 12As shown, the axial limiting structure 340 may include: a clamping groove 3421 and a clamping member 3411. The clamping groove 3421 is formed on the inner circumferential surface of the damping sleeve 342, and the clamping groove 3421 includes two groove walls 3422 oppositely arranged along the axial direction of the damping sleeve 342. The clamping member 3411 is arranged on the outer circumferential surface of the hollow shaft 341, and the clamping member 3411 is fitted into the clamping groove 3421 to be clamped between the two groove walls 3422. Thus, the structure of the damping assembly 34 is simple and the connection reliability is relatively high. However, the present invention is not limited thereto, and the axial limiting structure 340 may also be configured in other forms. For example, the arrangement positions of the clamping groove 3421 and the clamping member 3411 may be swapped.

[0123] In some embodiments, as Figure 13 and Figure 14 shown, the clamping groove 3421 may be an annular groove, and the clamping member 3411 may be an annular card. Thus, the structure of the axial limiting structure 340 is simple, convenient for machining and forming, and convenient for the clamping groove 3421 and the clamping member 3411 to be fitted and installed without the need to align in the circumferential direction.

[0124] In some embodiments, as Figure 12 shown, the two end faces on the axial two sides of the damping sleeve 342 are respectively a first end face 3423 and a second end face 3424. In the axial direction of the damping sleeve 342, the distance from the center of the clamping groove 3421 to the first end face 3423 is L1, and the distance from the center of the clamping groove 3421 to the second end face 3424 is L2, and L1 is less than L2 (i.e., L1 < L2). Thus, the operation of sleeving the damping sleeve 342 onto the hollow shaft 341 is convenient, thereby improving the assembly efficiency of the damping assembly 34.

[0125] In some embodiments, as Figure 12 shown, the inner hole of the damping sleeve 342 may include a first hole section 3425 and a second hole section 3426. The first hole section 3425 is located on the side close to the first end face 3423 of the central plane of the clamping groove 3421, and the second hole section 3426 is located on the side close to the second end face 3424 of the central plane of the clamping groove 3421. The aperture d1 of the first hole section 3425 is greater than the aperture d2 of the second hole section 3426. Thus, the operation of sleeving the damping sleeve 342 onto the hollow shaft 341 is convenient, thereby improving the assembly efficiency of the damping assembly 34.

[0126] In some embodiments, as Figure 11As shown, the first limiting structure 354a is a limiting ring 354 provided at the outer end of the support hole 353, and the limiting ring 354 stops at the outer end of the damping sleeve 342. Thereby, the assembly reliability of the damping assembly 34 and the box body assembly 35 can be ensured. Moreover, when the damping assembly 34 and the box body assembly 35 are in place, it is through the contact between the limiting ring 354 and the outer end of the damping sleeve 342, so that the damping effect of the damping sleeve 342 can be improved. Moreover, the structure of the first limiting structure 354a is simple, convenient for processing, and it is possible to observe whether the damping assembly 34 is installed in place through the inner ring area of the limiting ring 354. It should be noted that the "outer" mentioned in this paragraph and the following paragraph refers to the side away from the center of the box body assembly 35.

[0127] In some embodiments, as Figure 11 shown, the limiting ring 354 has a protruding portion 355 protruding from the outside to the inside, and the outer end of the damping sleeve 342 has a recessed portion 3427 for receiving the protruding portion 355. Thereby, when the protruding portion 355 and the recessed portion 3427 cooperate, they can play a role in dispersing force, so that the damping effect can be improved. However, the present invention is not limited thereto. For example, in Figure 15 the specific embodiment shown, the limiting ring 354 can also be arranged to directly cooperate with the recessed portion 3427 at the outer end of the damping sleeve 342, so that the occupied space of the box body assembly 35 in the extending direction of the support shaft 3201 can be saved, the compactness of the driving component 300 can be improved, and the use of the manufacturing material of the box body assembly 35 can also be saved.

[0128] In some embodiments, as Figure 11 shown, the second limiting structure 3202a can be a limiting shoulder 3202 provided on the support shaft 3201, and the limiting shoulder 3202 stops at the inner end of the hollow shaft 341. Thereby, the structure of the second limiting structure 3202a is simple and convenient for processing. It should be noted that the specific shape of the limiting shoulder 3202 is not limited. For example, it can be a continuous ring located on the circumference of the support shaft 3201 and coaxial with the support shaft 3201, or it can be a spaced convex platform, etc., which will not be elaborated here. It should be noted that the "inner" mentioned in this paragraph refers to the side close to the center of the box body assembly 35.

[0129] In some embodiments, as Figure 15 and Figure 16As shown, the driving component 300 may include: a driving motor 31, a driving gear assembly 32, and a transmission gear assembly 33. The driving gear assembly 32 may include an input gear 321a, and the input gear 321a is driven to rotate by the driving motor 31 (directly or indirectly). The transmission gear assembly 33 includes an anti-slip gear 331 and an output gear 332. The anti-slip gear 331 meshes with the input gear 321a for transmission, and the output gear 332 and the anti-slip gear 331 are cooperated through an anti-slip structure 330 to rotate synchronously in a non-slip state. The output gear 332 meshes with the driving rack 22 (combined Figure 17 ) for transmission. It should be noted that the anti-slip structure 330 described in this paragraph may be, but is not limited to, the anti-slip structure 330 described above.

[0130] In short, the driving motor 31 drives the input gear 321a to rotate. The input gear 321a meshes with the anti-slip gear 331 to rotate, and the anti-slip gear 331 and the output gear 332 are synchronously rotated through the anti-slip structure 330. Therefore, when the driving motor 31 drives the input gear 321a to rotate, the output gear 332 and the driving rack 22 can be driven to transmit in a non-slip state, so that the driving rack 22 can move along a set direction.

[0131] As Figure 15 shown, the box body assembly 35 may include a first box body 351 and a second box body 352 that are detachably connected. An accommodation cavity 350 is defined between the first box body 351 and the second box body 352. Combined Figure 16 as shown, the first box body 351 has a support hole 353 and a shaft through hole 3511, and the second box body 352 has a support hole 353 and an avoidance opening 3521. The input gear 321a, the anti-slip gear 331, and the output gear 332 are all rotating gears 320 and all have a support shaft 3201.

[0132] As Figure 15 and Figure 16 shown, the driving motor 31 is disposed on a side of the first box body 351 away from the second box body 352, and the motor shaft 311 of the driving motor 31 penetrates into the accommodation cavity 350 through the shaft through hole 3511. The driving gear assembly 32 and the transmission gear assembly 33 are both disposed in the accommodation cavity 350, and the input gear 321a is connected to the motor shaft 311. Combined Figure 11, the support shaft 3201 of the anti-slip gear 331 is rotatably engaged with the support hole 353 at the corresponding position on the first box body 351 through the first damping component 34a, that is, the support shaft 3201 of each anti-slip gear 331 is respectively rotatably engaged with a corresponding support hole 353 on the first box body 351 through a first damping component 34a. The support shaft 3201 of the output gear 332 is rotatably engaged with the support hole 353 at the corresponding position on the second box body 352 through the second damping component 34b, that is, the support shaft 3201 of each output gear 332 is respectively rotatably engaged with a corresponding support hole 353 on the second box body 352 through a second damping component 34b, and a part of the output gear 332 is exposed from the avoidance opening 3521. Combined with Figure 15 , the support shaft 3201 of the input gear 321a is rotatably engaged with the support hole 353 at the corresponding position on the second box body 352 through the third damping component 34c, that is, the support shaft 3201 of each input gear 321a is respectively rotatably engaged with a corresponding support hole 353 on the second box body 352 through a third damping component 34c. The first damping component 34a, the second damping component 34b and the third damping component 34c are all damping components 34.

[0133] Thus, the input gear 321a, the output gear 332, and the anti-slip gear 331 are all rotatably engaged with the box body assembly 35 through the damping component 34. Therefore, when the support shaft 3201 and the box body assembly 35 transmit vibration to each other, the damping can be performed through the damping component 34, thereby achieving the effects of damping and noise reduction.

[0134] At the same time, a damping shaft sleeve 323 can also be provided between the input gear 321a and the driving motor 31 (refer to Figure 2 shown), so as to reduce the vibration transmitted from the driving motor 31 to the inside of the box body assembly 35 during operation. Moreover, the output gear 332 and the anti-slip gear 331 are connected by an anti-slip structure 330 (as Figure 16 shown). Therefore, when the output gear 332 or the anti-slip gear 331 suddenly receives a large resistance, relative rotation can be made between the output gear 332 and the anti-slip gear 331 (that is, slipping occurs between the output gear 332 and the anti-slip gear 331). For example, when the output gear 332 jams, the driving motor 31 can still normally drive the anti-slip gear 331 to rotate, while the output gear 332 does not rotate at this time, thereby reducing the damage risk of the driving motor 31 when jamming occurs.

[0135] In some embodiments, such as Figure 16As shown, on the axial side of the anti-slip gear 331 (such as the first gear 331a in the implementation of the second aspect) in the anti-slip gear assembly 33a, which is far from the output gear 332 (such as the second gear 332a in the implementation of the second aspect), there may be a first receiving groove 3318. The anti-slip gear assembly 33a may include a first damping assembly 34a disposed in the first receiving groove 3318 (the first damping assembly 34a described in this paragraph may or may not be the damping assembly 34. For example, it may also be an ordinary damping gasket). On the axial side of the output gear 332 (such as the second gear 332a in the implementation of the second aspect), which is far from the anti-slip gear 331 (such as the first gear 331a in the implementation of the second aspect), there may be a second receiving groove 3326 (in combination with Figure 5 as shown). The anti-slip gear assembly 33a may include a second damping assembly 34b disposed in the second receiving groove 3326 (the second damping assembly 34b described in this paragraph may or may not be the damping assembly 34. For example, it may also be an ordinary damping gasket). Thus, by providing the first receiving groove 3318 and the second receiving groove 3326, the structural compactness of the anti-slip gear assembly 33a can be improved, and moreover, the positioning of the first damping assembly 34a and the second damping assembly 34b can be facilitated, and the assembly reliability is high.

[0136] Next, with reference to the drawings, the air conditioner 1000 according to the fourth aspect embodiment of the present invention will be described.

[0137] As Figure 17 and Figure 18 shown, the air conditioner 1000 according to the fourth aspect embodiment of the present invention may include: an air conditioner main body 100, a switch door component 200, and a driving component 300. The air conditioner main body 100 may include a blowing component 11 and a heat exchange component 12. There is a front air outlet area 101 on the air conditioner main body 100. In combination with Figures 19 - 20 , the switch door component 200 is disposed outside the air conditioner main body 100. In combination with Figure 21 , and the switch door component 200 includes a switch door 21 and a driving rack 22. In combination with Figures 19 - 20 , the switch door 21 is slidable up and down relative to the air conditioner main body 100 to open and close the front air outlet area 101. In combination with Figure 17 , the driving rack 22 is disposed inside the switch door 21 and extends in the up and down direction.

[0138] As Figure 16As shown, the driving component 300 may include a driving mechanism 301, and the driving mechanism 301 includes: a driving motor 31, a driving gear assembly 32, and a transmission gear assembly 33. The driving gear assembly 32 includes an input gear 321a, and the input gear 321a is driven by the driving motor 31 to rotate. The transmission gear assembly 33 includes an anti-slip gear 331 and an output gear 332. The anti-slip gear 331 meshes with and drives the input gear 321a, and the output gear 332 is cooperated with the anti-slip gear 331 through an anti-slip structure 330 to rotate synchronously in a non-slip state. The output gear 332 meshes with and drives the driving rack 22 (combined with Figure 17 ). It should be noted that the anti-slip structure 330 described in this paragraph may be, but is not limited to, the anti-slip structure 330 described above.

[0139] Thus, since the driving component 300 includes the driving gear assembly 32 and the transmission gear assembly 33 that meet the above-mentioned cooperation, the transmission ratio requirement can be met, and the running speed of opening and closing the door can be ensured. Moreover, since the output gear 332 is cooperated with the anti-slip gear 331 through the anti-slip structure 330, when the door 21 is subjected to an instantaneous impact force (for example, at the moment when the door 21 starts to move or is stuck by a foreign object, etc.), the output gear 332 and the anti-slip gear 331 can relatively rotate through the anti-slip structure 330 to achieve slipping, thereby avoiding the influence of the impact force on the driving motor 31 and effectively protecting the driving motor 31.

[0140] In some embodiments, as Figure 16 shown, the diameter of the output gear 332 is larger than the diameter of the anti-slip gear 331. It can be understood that since the anti-slip gear 331 and the output gear 332 rotate synchronously, when the output gear 332 meshes with and drives the driving rack 22, the speed of the anti-slip gear 331 on the meshing tangent line is higher than the speed of the output gear 332 on the meshing tangent line. Therefore, when the output gear 332 meshes with and drives the driving rack 22, it is equivalent to accelerating the speed transmitted to the driving rack 22, thereby increasing the running speed of the door 21, that is, the rapid lifting and lowering of the door 21 can be achieved.

[0141] In some embodiments, as Figure 21 and Figure 22 shown, the driving rack 22 has meshing teeth 221 on both sides perpendicular to the sliding direction of the door 21. The driving component 300 includes two groups of driving mechanisms 301, and the two groups of driving mechanisms 301 are axially symmetrically arranged and respectively correspond to and cooperate with the meshing teeth 221 on both sides of the driving rack 22 to jointly drive the door 21 to slide. Thus, by jointly driving the door 21 by the two groups of driving mechanisms 301, the working stability of the door 21 during sliding can be improved, the force and size of each group of driving mechanisms 301 can be reduced, and the service life and driving reliability of the driving mechanism 301 can be extended.

[0142] In some embodiments, such as Figure 1 shown, the drive gear assembly 32 may be a vibration damping gear assembly 32a. The vibration damping gear assembly 32a may include: a vibration damping gear 321, a drive shaft core 322, and a vibration damping bushing 323. Combining Figure 2 shown, the vibration damping gear 321 is an input gear 321a and has a central hole 3211. The drive shaft core 322 passes through the central hole 3211. The vibration damping bushing 323 includes a bushing portion 3231, a first end face portion 3232, and a second end face portion 3233. The bushing portion 3231 is sleeved on the drive shaft core 322 and passes through the central hole 3211, so that the drive shaft core 322 transmits torque to the vibration damping gear 321 through the vibration damping bushing 323. The first end face portion 3232 and the second end face portion 3233 are connected to the axial two ends of the bushing portion 3231 and are respectively located outside the axial two side end faces of the hub portion 3210 of the vibration damping gear 321. It should be noted that the detailed explanation of this paragraph can refer to the relevant parts of the first aspect embodiment above, and will not be elaborated here.

[0143] Thus, the bushing portion 3231 in the vibration damping bushing 323 is sleeved outside the drive shaft core 322, and the vibration damping gear 321 is sleeved outside the bushing portion 3231. In other words, the bushing portion 3231 is disposed between the vibration damping gear 321 and the drive shaft core 322, so that the bushing portion 3231 can transmit torque to the vibration damping gear 321 and achieve radial vibration damping of the vibration damping gear 321. At the same time, the first end face portion 3232 and the second end face portion 3233 in the vibration damping bushing 323 are respectively located outside the axial two side end faces of the hub portion 3210 of the vibration damping gear 321, so that the first end face portion 3232 and the second end face portion 3233 can be used to realize the fixed installation of the vibration damping gear 321 and the vibration damping bushing 323 and achieve axial vibration damping of the vibration damping gear 321.

[0144] At the same time, the vibration damping gear 321 may also generate a certain amount of vibration during operation. This part of the vibration will also be transmitted to the vibration damping bushing 323 first, and then after being vibration-damped by the vibration damping bushing 323, it will be transmitted to the drive shaft core 322 (or all absorbed by the bushing portion 3231 and no longer transmitted to the drive shaft core 322), so that the possibility of damage to the drive shaft core 322 when it is subjected to large vibrations can be reduced, and thus the service life of the drive shaft core 322 can be extended.

[0145] In short, the bushing portion 3231 can be used to enable the drive shaft core 322 to transmit torque to the vibration damping gear 321 and achieve radial vibration damping and noise reduction of the vibration damping gear 321. At the same time, the first end face portion 3232 and the second end face portion 3233 can be used to realize the relative axial limit of the vibration damping gear 321 and the vibration damping bushing 323, prevent the vibration damping gear 321 from separating from the vibration damping bushing 323, and achieve axial vibration damping and noise reduction of the vibration damping gear 321.

[0146] In some embodiments, as Figure 2 shown, the drive shaft core 322 may include a baffle portion 3221, and the baffle portion 3221 abuts against a side of the first end face portion 3232 away from the damping gear 321, so that the baffle portion 3221 and the damping gear 321 are isolated by the first end face portion 3232. Thus, by providing the baffle portion 3221, the relative axial position of the drive shaft core 322 and the damping gear 321 can be simply and effectively limited, preventing the drive shaft core 322 from disengaging from the damping gear 321 along the direction from the baffle portion 3221 to the first end face portion 3232, thereby simply and effectively improving the connection reliability between the drive shaft core 322 and the damping gear 321.

[0147] In addition, as described above, by providing the first end face portion 3232, the baffle portion 3221 and the damping gear 321 do not come into direct contact. A part of the vibration transmitted by the drive shaft core 322 can be first transmitted from the baffle portion 3221 to the first end face portion 3232 and absorbed by the first end face portion 3232, and then transmitted to the damping gear 321 (or all absorbed by the first end face portion 3232 and no longer transmitted to the damping gear 321). Therefore, after the damping effect of the first end face portion 3232, the vibration transmitted to the damping gear 321 can be reduced, thereby reducing the risk of damage to the damping gear 321, and further improving the service life of the damping gear assembly 32a to a certain extent.

[0148] As Figure 2 shown, the damping gear assembly 32a may further include a fixed end cover 324. As Figure 3 shown, the fixed end cover 324 may include a connecting portion 3241 and a stopping portion 3242. The connecting portion 3241 passes through the damping shaft sleeve 323 (that is, at least a part of the connecting portion 3241 penetrates into the damping shaft sleeve 323) and is connected to the drive shaft core 322. The stopping portion 3242 abuts against a side of the second end face portion 3233 away from the damping gear 321, so that the stopping portion 3242 and the damping gear 321 are isolated by the second end face portion 3233. Thus, the fixed end cover 324 can be used to simply and effectively limit the relative axial position of the drive shaft core 322 and the damping gear 321, preventing the drive shaft core 322 from disengaging from the damping gear 321 along the direction from the stopping portion 3242 to the second end face portion 3233, thereby simply and effectively improving the connection reliability between the drive shaft core 322 and the damping gear 321, and making the assembly of the damping gear assembly 32a convenient and efficient.

[0149] In addition, since the second end face portion 3233 is located between the stopper portion 3242 and the damping gear 321, at this time, the stopper portion 3242 and the damping gear 321 do not come into direct contact. A part of the vibration transmitted by the drive shaft core 322 can be transmitted to the stopper portion 3242 first, then from the stopper portion 3242 to the second end face portion 3233, and then to the damping gear 321 (or all absorbed by the second end face portion 3233 and no longer transmitted to the damping gear 321). Therefore, after the damping effect of the second end face portion 3233, the vibration transmitted to the damping gear 321 can be reduced, thereby reducing the risk of damage to the damping gear 321, and further improving the service life of the damping gear assembly 32a to a certain extent.

[0150] In some embodiments, as Figure 5 shown, the anti-slip gear 331 can be the first gear 331a, the output gear 332 can be the second gear 332a. The first gear 331a has a first annular portion 3311, the outer ring of the first annular portion 3311 has a first mating portion 3312, and the first mating portion 3312 is provided with an elastic buckle 3314. As Figure 6 shown, the second gear 332a has a second annular portion 3321. Combining Figure 7 , the second annular portion 3321 is sleeved outside the first mating portion 3312. The center of the inner cavity of the second annular portion 3321 has a cylindrical surface boss 3322. The cylindrical surface boss 3322 is rotatably inserted into the first annular portion 3311. A plurality of positioning grooves 3325 are circumferentially and spacedly distributed on the inner peripheral wall of the second annular portion 3321. The elastic buckle 3314 is adapted to cooperate with any one of the positioning grooves 3325 to form an anti-slip structure 330. When the elastic buckle 3314 cooperates with the positioning groove 3325, the first gear 331a and the second gear 332a rotate synchronously. It should be noted that the detailed explanation of this paragraph can refer to the relevant parts of the second aspect of the embodiments above and will not be elaborated here.

[0151] For example, when the anti-slip gear assembly 33a is working, the first gear 331a and the second gear 332a transmit torque through the cooperation of the elastic buckle 3314 and the positioning groove 3325, so that the first gear 331a and the second gear 332a can rotate synchronously. However, when one of the first gear 331a and the second gear 332a is subjected to a large resistance, or when the first gear 331a or the second gear 332a suddenly rotates or suddenly stops, since the elastic buckle 3314 can undergo elastic deformation, the elastic buckle 3314 slides out of the positioning groove 3325 with which it cooperates and enters into an adjacent or spaced positioning groove 3325 (depending on the magnitude of the impact force), that is, the first gear 331a and the second gear 332a slip. In other words, at this time, relative movement will occur between the first gear 331a and the second gear 332a until the slipping between the first gear 331a and the second gear 332a no longer occurs, and the first gear 331a and the second gear 332a can resume synchronous rotation.

[0152] It can be understood that the rotational force output by the drive motor 31 is less than the force for the elastic deformation of the elastic buckle 3314. Thus, after the impact force decreases or disappears, the first gear 331a and the second gear 332a can rotate synchronously to meet the requirement of synchronous rotation of the first gear 331a and the second gear 332a in a non-slip state.

[0153] Moreover, by setting the cooperation of the cylindrical surface boss 3322 and the first ring portion 3311, the rotation centers of the cylindrical surface boss 3322 and the first ring portion 3311 can be prevented from shifting randomly, thereby avoiding the deformation problem of the first engaging portion 3312 due to the shift. Furthermore, the reliable cooperation between the elastic buckle 3314 and the positioning groove 3325 can be ensured, thus ensuring the reliability of power transmission. Also, by setting the cylindrical surface boss 3322, the structural strength of the second gear 332a having the positioning groove 3325 can be improved, thereby increasing the service life of the anti-slip gear assembly 33a. In addition, in the case of slipping, by setting the cooperation of the cylindrical surface boss 3322 and the first ring portion 3311, it can be ensured that the first gear 331a and the second gear 332a can rotate relatively stably, enabling the elastic buckle 3314 to cooperate with other positioning grooves 3325.

[0154] In some embodiments, as Figure 15 shown, the drive component 300 may further include a box body assembly 35. The box body assembly 35 may include a first box body 351 and a second box body 352 that are detachably connected. An accommodation cavity 350 is defined between the first box body 351 and the second box body 352. Combining Figure 16 shown, the first box body 351 has a shaft through-hole 3511, and the second box body 352 has an avoidance opening 3521. Combining Figure 15As shown, the drive motor 31 is disposed on a side of the first housing 351 away from the second housing 352, and the motor shaft 311 of the drive motor 31 penetrates into the accommodation cavity 350 through the shaft through-hole 3511. In combination with Figure 16 As shown, both the drive gear assembly 32 and the transmission gear assembly 33 are disposed in the accommodation cavity 350, and the input gear 321a is connected to the motor shaft 311, and a part of the output gear 332 is exposed from the avoidance opening 3521 (as Figure 8 shown).

[0155] Thus, the structure of the drive component 300 is simple, convenient for disassembly and assembly, and has a high integration degree, enabling rapid installation. In addition, the drive gear assembly 32 and the transmission gear assembly 33 can be protected by the housing assembly 35, improving the service life of the drive component 300.

[0156] In some embodiments, as Figure 16 shown, the first housing 351 and the second housing 352 are respectively provided with support holes 353. The input gear 321a, the anti-slip gear 331, and the output gear 332 are all rotating gears 320 and have support shafts 3201. The support shaft 3201 of the anti-slip gear 331 is rotatably fitted with the support hole 353 at the corresponding position on the first housing 351 through the first damping assembly 34a, and the support shaft 3201 of the output gear 332 is rotatably fitted with the support hole 353 at the corresponding position on the second housing 352 through the second damping assembly 34b. The support shaft 3201 of the input gear 321a is rotatably fitted with the support hole 353 at the corresponding position on the second housing 352 through the third damping assembly 34c.

[0157] Thus, the input gear 321a, the output gear 332, and the anti-slip gear 331 are respectively rotatably fitted with the housing assembly 35 through the first damping assembly 34a, the second damping assembly 34b, and the third damping assembly 34c. When the support shaft 3201 and the housing assembly 35 transmit vibrations to each other, vibration damping can be performed through the first damping assembly 34a, the second damping assembly 34b, and the third damping assembly 34c, thus achieving the effects of vibration damping and noise reduction.

[0158] Meanwhile, a damping bushing 323 can also be provided between the input gear 321a and the drive motor 31 (refer to Figure 2 shown), so as to reduce the vibration transmitted from the drive motor 31 to the housing assembly 35 during operation. Moreover, the output gear 332 and the anti-slip gear 331 are connected by an anti-slip structure 330 (as Figure 16As shown, when the output gear 332 or the anti-slip gear 331 suddenly encounters a large resistance, relative rotation can occur between the output gear 332 and the anti-slip gear 331 (i.e., slipping between the output gear 332 and the anti-slip gear 331). For example, when the output gear 332 jams, the drive motor 31 can still normally drive the anti-slip gear 331 to rotate, while the output gear 332 does not rotate at this time, thereby reducing the risk of damage to the drive motor 31 when jamming occurs.

[0159] In some embodiments, as Figure 16 shown, at least one of the first damping assembly 34a, the second damping assembly 34b, and the third damping assembly 34c is the damping assembly 34, as Figure 10 and Figure 11 shown, the damping assembly 34 is sleeved on the support shaft 3201 and passes through the support hole 353. The box body assembly 35 has a first limiting structure 354a, and the rotating gear 320 has a second limiting structure 3202a. In the axial direction of the rotating gear 320, the first limiting structure 354a and the second limiting structure 3202a stop on both axial sides of the damping assembly 34. Thus, the damping assembly 34 has a simple structure, is convenient for installation, and has good damping effect.

[0160] In some embodiments, as Figure 19 shown, the air conditioner body 100 may further have an upward air outlet area 102, and the upward air outlet area 102 is located above the front air outlet area 101. Combining Figure 18 and Figure 23 , a first air duct 111 and a second air duct 112 are defined in the air supply component 11. The first air duct 111 includes an upstream air duct cavity 1111 and a downstream air duct cavity 1112 provided above the upstream air duct cavity 1111. The second air duct 112 is provided in the downstream air duct cavity 1112 and is isolated from the first air duct 111. The downstream air duct cavity 1112 is respectively communicated with the upward air outlet area 102 and the front air outlet area 101, and the second air duct 112 is communicated with the front air outlet area 101. The air supply component 11 further includes a first fan assembly 113 provided in the upstream air duct cavity 1111 and a second fan assembly 114 provided in the second air duct 112. The heat exchange component 12 is located at the inlets of the first air duct 111 and the second air duct 112. Thus, multi-air-sensation mode air outlet of the air conditioner 1000 can be realized, thereby enhancing the user experience.
