[0050] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the drawings. Detailed implementation manners

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0052] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood 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.

[0053] In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B simultaneously.

[0054] The present invention provides a drive component, an air conditioner indoor unit and an air conditioner. Among them, the drive component is used for the air conditioner indoor unit, and the air conditioner indoor unit can be a floor-mounted air conditioner indoor unit or a vertical wall-mounted air conditioner indoor unit, etc. The following takes the floor-mounted air conditioner indoor unit as an example for illustration, but it is not used to limit the present invention.

[0055] Specifically, as Figure 1 and 2 shown, the air conditioner indoor unit generally includes a housing 200 and a damper 600. The housing 200 has an air outlet 210 that extends in the up and down directions; the damper 600 is rotatably provided in the housing 200 to open or close the air outlet 210.

[0056] Among them, the driving component 100 is used to drive the air damper 600 to rotate. Specifically, the driving component 100 is installed in the housing 200 and is arranged below the air outlet 210. The lower end of the air damper 600 is installed on the driving ring 20 of the driving component 100. The driving component 100 drives the air damper 600 to rotate by driving the driving ring 20 to open or close the air outlet 210.

[0057] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (such as shown in the attached Figure 3 and 10 figure). If this specific posture changes, then such directional indications will also change accordingly.

[0058] Generally, as Figure 1 and 2 shown, the housing 200 further has an air inlet 220 and a heat exchange air duct connecting the air inlet 220 and the air outlet 210.

[0059] Generally, as Figure 1 shown, the air conditioner indoor unit 1000 further includes an indoor heat exchanger 300 arranged in the heat exchange air duct. The indoor heat exchanger 300 is used to adjust the indoor air temperature, such as refrigeration or heating.

[0060] Generally, as Figure 1 shown, the air conditioner indoor unit 1000 further includes a blower wheel 400 arranged in the heat exchange air duct. The blower wheel 400 is used to drive the air to flow. Among them, the blower wheel 400 can be selected as a cross-flow blower wheel 400. Optionally, the blower wheel 400 is arranged on the air outlet side of the indoor heat exchanger 300.

[0061] Generally, as Figure 1 and 2 shown, the air conditioner indoor unit 1000 further includes a wind guiding component 500 arranged in the heat exchange air duct. The wind guiding component 500 is used to change the air flow direction to change the air supply direction of the air conditioner indoor unit 1000.

[0062] Generally, the housing 200 includes a front shell 230 and a rear shell 240. The air inlet 220 is arranged on the rear shell 240, and the air outlet 210 is arranged on the front shell 230.

[0063] In an embodiment of the present invention, as Figure 3 、 5 and shown in 10, the driving component 100 includes a base 10, a driving ring 20 and an upper cover 30.

[0064] Among them, the base 10 is installed on the housing 200.

[0065] Among them, as Figure 3 , 8 and as shown in 10, the driving ring 20 is rotatably mounted on the upper surface of the base 10, and the lower end of the air damper 600 is mounted on the driving ring 20. Thus, by driving the driving ring 20 to rotate, the air damper 600 can be driven to rotate, that is to say, the driving ring 20 can be used to drive the air damper 600 to rotate.

[0066] In this embodiment, as Figure 10 shown, the upper surface of the base 10 is provided with an annular mounting groove 11, and the driving ring 20 is rotatably mounted in the annular mounting groove 11. Thus, by providing the annular mounting groove 11 to mount the driving ring 20, it is convenient to limit the driving ring 20, so as to improve the stability of the rotation of the driving ring 20 and the air damper 600.

[0067] In this embodiment, as Figure 10 shown, the driving ring 20 includes a ring body (not labeled in the figure) and a connecting ring convex (not labeled in the figure) provided at the upper end of the ring body. The connecting ring convex protrudes laterally from the outer ring surface of the ring body; the lower end of the ring body is inserted into the annular mounting groove 11, and the connecting ring convex is provided above the peripheral edge of the notch of the annular mounting groove 11. Among them, a notch is provided on the connecting ring convex.

[0068] Among them, as Figure 5 , 8 and as shown in 10, the upper cover 30 is provided at the upper opening of the driving ring 20. Thus, the inner space of the driving ring 20 can be protected. Specifically, the inner space of the driving ring 20 can be used to install a transmission device for driving the driving ring 20 to rotate or other components for driving the air conditioner indoor unit 1000 (such as the air guiding assembly 500, etc.). The upper cover 30 can be used to protect these transmission devices to improve the reliability of the driving assembly 100 and the air conditioner indoor unit 1000.

[0069] Furthermore, as Figure 6 , 7 and as shown in 10, a screw hole column 31 (i.e., a connecting column with a threaded hole) protrudes from the lower surface of the upper cover 30 or the upper surface of the base 10, so as to threadedly connect the upper cover 30 and the base 10 through the screw hole column 31. Among them, threadedly connecting the upper cover 30 and the base 10 through the screw hole column 31 has the following two meanings: 1) A threaded fastener (such as a screw or a stud, etc.) passes through the upper cover 30 or the base 10 and is threadedly connected to the screw hole column 31 to threadedly connect the upper cover 30 and the base 10; 2) The screw hole column 31 is used to support the upper cover 30 so that the upper cover 30 is fixed at the upper opening of the driving ring 20.

[0070] Thus, by providing the screw hole columns 31, not only can the upper cover 30 be conveniently connected to the base 10, making the connection between the upper cover 30 and the base 10 simple and firm, but also the upper cover 30 can be supported by the screw hole columns 31 so that the upper cover 30 is fixed at the upper opening of the driving ring 20.

[0071] In this embodiment, as Figure 10 shown, the screw hole columns 31 are provided on the lower surface of the upper cover 30, the lower ends of the screw hole columns 31 abut against the upper surface of the base 10, and the upper surface of the base 10 is provided with connection through holes 12 located within the limit sleeve 13. The connection through holes 12 are correspondingly arranged with the threaded holes on the screw hole columns 31, and threaded fasteners (such as screws or studs, etc.) pass through the connection through holes 12 and are threadedly connected to the screw hole columns 31. Among them, the connection through holes 12 penetrate the base 10 in the vertical direction, and the threaded fasteners pass through the connection through holes 12 from below the base 10 and are threadedly connected to the screw hole columns 31. Thus, the upper cover 30 can be threadedly connected to the base 10 through the screw hole columns 31.

[0072] In this embodiment, as Figure 6 shown, optionally, a reinforcing rib (not labeled in the figure) connecting the screw hole column 31 and the lower surface of the upper cover 30 is further provided outside the screw hole column 31 to enhance the structural strength of the screw hole column 31.

[0073] In this embodiment, optionally, the connection through hole 12 is a threaded hole.

[0074] Of course, in other embodiments, other methods can also be used to threadedly connect the upper cover 30 and the base 10 through the screw hole columns 31.

[0075] For example, in another part of the embodiments, the screw hole columns 31 are provided on the lower surface of the upper cover 30, the upper surface of the base 10 is provided with connection columns located within the limit sleeve 13, the connection columns are provided with connection through holes 12, the screw hole columns 31 abut against the connection columns, the connection through holes 12 are correspondingly arranged with the threaded holes on the screw hole columns 31, and threaded fasteners (such as screws or studs, etc.) pass through the connection through holes 12 and are threadedly connected to the screw hole columns 31. Among them, the connection through holes 12 penetrate the base 10 in the vertical direction, and the threaded fasteners pass through the connection through holes 12 from below the base 10 and are threadedly connected to the screw hole columns 31. Thus, the upper cover 30 can also be threadedly connected to the base 10 through the screw hole columns 31. At the same time, the connection strength can be improved to enhance the connection reliability between the upper cover 30 and the base 10. In this part of the embodiments, optionally, the connection through hole 12 is a threaded hole, and the connection column is also a screw hole column.

[0076] For another example, in some other embodiments, the threaded stud 31 is provided on the upper surface of the base 10; a connection through-hole 12 corresponding to the threaded hole of the threaded stud 31 is provided on the upper surface of the upper cover 30, and a threaded fastener passes through the connection through-hole 12 and is threadedly connected to the threaded stud 31. Among them, the connection through-hole 12 penetrates the upper cover 30 in the up-down direction, and the threaded fastener passes through the connection through-hole 12 from above the upper cover 30 to be threadedly connected to the threaded stud 31. In this way, the upper cover 30 can be threadedly connected to the base 10 through the threaded stud 31. In this part of the embodiments, optionally, the connection through-hole 12 is a threaded hole.

[0077] It can be understood that since the driving ring 20 is used to drive the air damper 600 to rotate, the air damper 600 is installed on one side of the driving ring 20, and the driving ring 20 is unevenly stressed during the rotation process. As a result, the driving ring 20 will compress / squeeze the upper cover 30 during the rotation process, and then the upper cover 30 will compress / squeeze the threaded stud 31, so that the threaded stud 31 is easily damaged. To solve this problem, in the present invention, a limiting sleeve 13 is arranged outside the threaded stud 31 to support and limit the threaded stud 31 to protect the threaded stud 31.

[0078] Specifically, as Figure 6 - 10 shown, a limiting sleeve 13 protrudes from the upper surface of the base 10, and the threaded stud 31 is arranged inside the limiting sleeve 13. In this way, during the rotation of the driving ring 20, the force received by the threaded stud 31 can be transferred to the limiting sleeve 13 to protect the threaded stud 31 and reduce the risk of damage to the threaded stud 31. In addition, when assembling the upper cover 30 and the base 10, the limiting sleeve 13 can also play a role in guiding and initial positioning to reduce the assembly difficulty of the upper cover 30 and the base 10.

[0079] It can be understood that from the above analysis, the threaded stud 31 will compress / squeeze the limiting sleeve 13 during the rotation of the driving ring 20, so that the limiting sleeve 13 will break from the root of the limiting sleeve 13 due to local stress deformation. Moreover, since the driving assembly 100 is arranged below the air outlet 210, the condensed water generated by the components (such as the air guiding assembly 500, etc.) arranged at the air outlet 210 may enter the inner space of the driving ring 20, so it is easy to accumulate water in the limiting sleeve 13, thus easily corroding the threaded fastener and affecting the connection stability between the upper cover 30 and the base 10.

[0080] In the present invention, to solve the above problems, a water leakage through-hole communicating with the sleeve hole of the limiting sleeve 13 is provided on the limiting sleeve 13 to release the stress when the limiting sleeve 13 is stressed and prevent water accumulation.

[0081] Specifically, as Figure 6 - 9As shown, a water leakage through-hole communicating with the sleeve hole of the limit sleeve 13 is provided on the limit sleeve 13, wherein the water leakage through-hole penetrates the sleeve wall of the limit sleeve 13. In this way, when the screw hole column 31 presses / squeezes the limit sleeve 13, the water leakage through-hole can release the stress of the limit sleeve 13 when it is stressed, so as to eliminate or weaken the local stress condition of the limit sleeve 13, thereby preventing the positioning sleeve from breaking due to local stress, and thus improving the connection stability between the upper cover 30 and the base 10, making the fixation of the upper cover 30 and the base 10 more stable. At the same time, the water leakage through-hole can make the water entering the limit sleeve 13 flow out / drain, so as to prevent water accumulation in the limit sleeve 13, and improve the reliability of the connection between the upper cover 30 and the base 10.

[0082] It should be pointed out here that for the drive assembly 100 of the present invention, by providing the screw hole column 31 on the lower surface of the upper cover 30 or the upper surface of the base 10, the upper cover 30 and the base 10 are threadedly connected through the screw hole column 31, which not only makes the connection between the upper cover 30 and the base 10 simple and firm, but also can support the upper cover 30 through the screw hole column 31 to fix the upper cover 30 at the upper opening of the drive ring 20.

[0083] At the same time, by providing the limit sleeve 13 outside the screw hole column 31, it can not only play a guiding and preliminary positioning role when assembling the upper cover 30 and the base 10, so as to reduce the assembly difficulty of the upper cover 30 and the base 10; but also protect the screw hole column 31, so as to reduce the risk of damage to the screw hole column 31 and improve the connection stability between the upper cover 30 and the base 10.

[0084] At the same time, by providing the water leakage through-hole on the limit sleeve 13, it can not only release the stress of the limit sleeve 13 when it is stressed, so as to eliminate or weaken the local stress condition of the limit sleeve 13, thereby preventing the positioning sleeve from breaking due to local stress; but also prevent water accumulation in the limit sleeve 13, and further improve the connection stability and reliability between the upper cover 30 and the base 10.

[0085] Furthermore, as Figure 6 - 9 shown, the water leakage through-hole is a water leakage notch 131. Wherein, the water leakage notch 131 interrupts the limit sleeve 13 in the circumferential direction of the limit sleeve 13. In this way, it can not only improve the stress release ability of the water leakage through-hole to further reduce the risk of fracture of the limit sleeve 13; but also improve the drainage efficiency; and can also reduce the forming difficulty of the limit sleeve 13 to reduce the production cost; and so on.

[0086] Furthermore, as Figure 6 and 8As shown, a plurality (i.e., greater than or equal to two) of the limit sleeves 13 are spaced apart on the upper surface of the base 10, and each limit sleeve 13 is provided with a screw hole column 31. In this way, by providing multiple groups of screw hole columns 31 and limit sleeves 13, the connection strength between the upper cover 30 and the base 10 can be improved, and the connection stability between the upper cover 30 and the base 10 can be improved.

[0087] Optionally, the sizes of the multiple limit sleeves 13 can be the same or different, and the present invention does not limit this.

[0088] Furthermore, as Figure 6 and 8 shown, at least some of the limit sleeves 13 are arranged close to the driving ring 20. Among them, the screw hole columns 31 in the limit sleeves 13 are also arranged close to the driving ring 20. It can be understood that the closer the limit sleeve 13 and the screw hole column 31 therein are to the periphery of the upper cover 30 or the base 10, the shorter the force arm of the driving ring 20 acting on the screw hole column 31, the smaller the acting force received by the screw hole column 31, the more stable the connection between the upper cover 30 and the base 10, and the more stable the edge of the upper cover 30.

[0089] In this way, by arranging at least some of the limit sleeves 13 close to the driving ring 20, the connection stability between the upper cover 30 and the base 10 can be improved, and thus the reliability of the driving assembly 100 can be improved.

[0090] In this embodiment, a plurality of limit sleeves 13 and the screw hole columns 31 therein are all arranged close to the driving ring 20. Of course, in other embodiments, only most of the limit sleeves 13 and the screw hole columns 31 therein can be arranged close to the driving ring 20.

[0091] Furthermore, as Figure 6 - 9 shown, the water leakage notch 131 is arranged towards the inner ring surface of the driving ring 20.

[0092] From the above analysis, it can be seen that arranging the limit sleeve 13 close to the driving ring 20 is beneficial to improving the connection stability between the upper cover 30 and the base 10, and it can be understood that the sleeve wall of the limit sleeve 13 where the water leakage notch 131 is formed is missing. Based on this, by arranging the water leakage notch 131 towards the inner ring surface of the driving ring 20, it can be obtained that the limit sleeve 13 can be arranged closer to the driving ring 20, thereby further improving the connection stability between the upper cover 30 and the base 10.

[0093] Specifically, as Figure 6 - 9 shown, the limit sleeve 13 has two notch side edges (not marked in the figure) for forming the water leakage notch 131. Among them, the two notch side edges are arranged relatively spaced apart to form the water leakage notch 131.

[0094] Furthermore, as Figure 7 and 9As shown, the notch side edge has a connecting surface 132 facing the inner ring surface of the driving ring 20, and the connecting surface 132 connects the inner ring surface and the outer ring surface of the limiting sleeve 13. Optionally, the inner ring surface of the driving ring 20 and the connecting surface 132 are offset.

[0095] In this way, on the one hand, the notch side edge can avoid the inner ring surface of the driving ring 20 to prevent the notch side edge from affecting the rotation of the driving ring 20, and on the other hand, the limiting sleeve 13 can be arranged closer to the driving ring 20.

[0096] Furthermore, as Figure 7 and 9 shown, the connecting surface 132 is arc-transitionally connected to the inner ring surface of the limiting sleeve 13. In this way, on the one hand, it is convenient for the forming of the limiting sleeve 13, and on the other hand, the wall thickness of the connection between the connecting surface 132 and the inner ring surface of the limiting sleeve 13 can be increased to prevent the notch side edge from being deformed and damaged when the driving ring 20 rotates.

[0097] Furthermore, as Figure 6 - 9 shown, the shape of the limiting sleeve 13 is circular. In this way, the screw hole column 31 can be better protected. Of course, in other embodiments, the limiting sleeve 13 can also be set to other shapes, such as square, or with a circular inner and a square outer.

[0098] Specifically, as Figure 7 and 9 shown, the connecting surface 132 is a cylindrical surface, and the inner ring surface of the limiting sleeve 13 is concentric with the connecting surface 132. In this way, the limiting sleeve 13 can better avoid the inner ring surface of the driving ring 20.

[0099] Furthermore, as Figure 7 shown, the central angle α of the sector corresponding to the water leakage notch 131 is at most 180 degrees. Among them, as Figure 7 shown, the central angle α of the sector corresponding to the water leakage notch 131 refers to the included angle between the two inner sides (the intersection lines of the connecting surface 132 and the inner ring surface of the limiting sleeve 13) of the water leakage notch 131 and the center line of the limiting sleeve 13 in the cross-section of the limiting sleeve 13. It should be noted that this feature of the water leakage notch 131 can also be represented by the ratio of the circumferential length of the water leakage notch 131 to the circumferential length of the ring where the limiting sleeve 13 is located, that is, the ratio of the circumferential length of the water leakage notch 131 to the circumferential length of the ring where the limiting sleeve 13 is located is at most 1 / 2.

[0100] In this way, the situation that the central angle α is too large can be avoided, so that when the limiting sleeve 13 approaches the inner ring surface of the driving ring 20 to a large extent, the limiting and protecting effects of the limiting sleeve 13 on the screw hole column 31 can still be ensured.

[0101] Optionally, the central angle of the sector corresponding to the water leakage notch 131 is at least 30 degrees and at most 120 degrees. At this time, the ratio of the circumferential length of the water leakage notch 131 to the circumferential length of the ring where the limiting sleeve 13 is located is at least 1 / 12 and at most 1 / 3. In this way, the drainage effect, avoidance effect, etc. of the water leakage notch 131 and the limiting effect of the limiting sleeve 13 on the screw hole column 31 can be taken into account.

[0102] It should be noted here that the distribution of the water leakage notch 131 and the structure of the limiting sleeve 13 can also be set from other angles. For example, in another embodiment of the present invention, a plurality of water leakage notches 131 can be arranged at intervals in the circumferential direction of the limiting sleeve 13. In this way, it can effectively prevent water from accumulating in the limiting sleeve 13, greatly improve the stress release ability when the limiting sleeve 13 is stressed, and ensure the limiting and protection effects of the limiting sleeve 13 on the screw hole column 31. In this embodiment, optionally, for one limiting sleeve 13, two water leakage notches 131 are provided, and the two water leakage notches 131 are arranged oppositely to divide the limiting sleeve 13 into two relatively arranged limiting sub-sleeves, and the two limiting sub-sleeves are arranged at intervals in the radial direction of the limiting sleeve 13.

[0103] Furthermore, as Figure 8 and 10 shown, a receiving sink 22 is formed at the upper opening of the driving ring 20, a mating ring convex 32 protrudes laterally from the upper end of the periphery of the upper cover 30, the lower end of the periphery of the upper cover 30 extends into the driving ring 20, and the mating ring convex 32 is received in the receiving sink 22. In this way, the upper cover 30 can be hidden in the driving ring 20 and can better cover the upper opening of the driving ring 20.

[0104] In this embodiment, optionally, the receiving sink 22 is provided at the upper opening (i.e., the ring opening) of the connecting ring convex.

[0105] Furthermore, as Figure 6 - 10 shown, a driving tooth 21 is provided on the inner ring surface of the driving ring 20. The driving assembly 100 further includes a driving motor 40 and a transmission gear 50 meshed with the driving tooth 21. The driving motor 40 is provided on the lower surface of the base 10, and the driving motor 40 is used to drive the transmission gear 50 to rotate to drive the driving ring 20 to rotate. Among them, the transmission gear 50 is rotatably provided in the inner space of the driving ring 20, and the upper cover 30 can protect the transmission gear 50.

[0106] During operation, the driving motor 40 drives the transmission gear 50 to rotate, drives the driving ring 20 to rotate through the meshing transmission between the transmission gear 50 and the driving ring 20, and the driving ring 20 rotates to drive the air door 600 to rotate, so as to open or close the air outlet 210.

[0107] In this embodiment, optionally, the drive motor 40 is installed on the lower surface of the base 10. The output shaft of the drive motor 40 passes through the base 10 and extends into the inner side of the drive ring 20 and is connected to the transmission gear 50 to drive the transmission gear 50 to rotate.

[0108] In this embodiment, optionally, the drive teeth 21 are arranged on the inner ring surface of the ring body.

[0109] Optionally, in the circumferential direction of the drive ring 20, the drive teeth 21 can be distributed on the entire inner ring surface of the drive ring 20 (as shown in Figure 6 and 8 ), or can be distributed in a partial area of the inner ring surface of the drive ring 20 (as shown in Figure 10 ).

[0110] Of course, in other embodiments, other methods can also be used to drive the drive ring 20 to rotate, such as setting the drive teeth 21 on the outer ring surface of the drive ring 20 and setting the transmission gear 50 on the outside of the drive ring 20; and so on.

[0111] Furthermore, as shown in Figure 1 and 2 , the air guiding assembly 500 includes an air outlet frame. The air outlet frame is rotatably installed in the heat exchange air duct and is arranged close to the air outlet 210. The rotation axis of the air outlet frame extends in the up and down direction. When the air outlet frame rotates, the air supply direction of the air outlet frame can be changed, so that the left and right air supply ranges of the air conditioner indoor unit 1000 can be increased.

[0112] Furthermore, the air guiding assembly 500 further includes a plurality of louvers rotatably arranged inside the air outlet frame. The louvers can swing up and down to change the up and down air supply range. Optionally, the louvers are rotatably installed on the air outlet frame.

[0113] Furthermore, as shown in Figure 4 , 6 , 8 and 10, the drive assembly 100 further includes a second motor 71, a second gear 72 and a third gear 73 meshing with the second gear 72. The second motor 71 is installed on the lower surface of the base 10. The output shaft of the second motor 71 passes through the base 10 and extends into the inner side of the drive ring 20 and is connected to the second gear 72 to drive the second gear 72 to rotate. An installation column 74 connected to the air outlet frame is arranged on the third gear 73. An installation hole 33 for the installation column 74 to pass through is arranged on the upper cover 30. Among them, the second gear 72 and the third gear 73 are rotatably arranged in the inner space of the drive ring 20, and the upper cover 30 can protect the second gear 72 and the third gear 73.

[0114] Thus, the second motor 71 drives the second gear 72 to rotate, and the second gear 72 drives the third gear 73 to rotate, so as to drive the air outlet frame to rotate.

[0115] Optionally, a third motor 75 for driving the louver to swing is further provided on the lower surface of the base 10.

[0116] Furthermore, in order to improve the rotational stability of the air door 600, another driving structure is further provided above the air outlet 210 to drive the air door 600 to rotate simultaneously. In order to simplify the structure of the air conditioner indoor unit 1000 and reduce costs, this driving structure can also adopt the above-mentioned driving assembly 100.
