DETAILED DESCRIPTION

[0056] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0058] Refer to the following Figures 1 to 10 The air outlet frame driving mechanism 100 and the air conditioner 200 according to some embodiments of the present invention are described.

[0059] like Figure 1 and Figure 2As shown, the air outlet frame drive mechanism 100 provided by the embodiment of the first aspect of the present invention is used for an air conditioner 200. It is understood that the air conditioner 200 can be a split air conditioner, a central air conditioner, a mobile air conditioner, etc., which are not listed here one by one. It is understood that the air conditioner 200 has a shell, a heat exchange device (such as a condenser, an evaporator), a fan, an air duct, an air outlet frame 210 and other components, the shell has a storage space, the heat exchange device (such as a condenser, an evaporator), the fan, the air duct, the air outlet frame 210 and other components are accommodated in the storage space 1271, the air outlet frame 210 is connected to the air outlet frame drive mechanism 100 so that the air outlet frame 210 moves under the drive of the air outlet frame drive mechanism 100, thereby adjusting the air supply angle of the air outlet frame 210 and expanding the air supply range of the air outlet frame 210. Further, the shell has a panel bracket, and the air outlet frame drive mechanism 100 is connected to the panel bracket. In this way, the connection of the air outlet frame drive mechanism 100 is more reliable, thereby making the air outlet frame drive mechanism 100 drive more smoothly.

[0060] Specifically, if Figure 1 and Figure 5 As shown, the air outlet frame drive mechanism 100 includes: a first drive part 110 and a second drive part 120, the first drive part 110 has a movable part 111 and a first drive device 112, the movable part 111 is provided with a connecting structure 1111 for connecting with the air outlet frame 210, the first drive device 112 is connected to the movable part 111 and drives the movable part 111 to move, wherein the movement of the movable part 111 has a first position and a second position; the second drive part 120 is connected to the first drive part 110, and the second drive part 120 is configured to drive the first drive part 110 to move, and the movement of the first drive part 110 has a third position and a fourth position.

[0061] The air outlet frame driving mechanism 100 provided in the above embodiment of the present invention, the air outlet frame 210 is connected to the movable part 111, and the first driving device 112 drives the movable part 111 to move between the first position and the second position, that is, the air outlet frame 210 moves with the movable part 111 between the first position and the second position, and the movable amount of the air outlet frame 210 is released by the movable part 111, so that the air outlet frame 210 has a larger air supply angle, thereby improving the user experience of the product, and the second driving part 120 drives the first driving part 110 to move between the third position and the fourth position, that is, the second driving part 120 drives the first driving part 110 and the air outlet frame 210 to move between the third position and the fourth position. Compared with the existing solution in which the air outlet frame 210 is driven to move unidirectionally by the motion mechanism, this solution utilizes the first driving part 110 and the second driving part 120 to realize the bidirectional movement of the air outlet frame 210, thereby expanding the air supply angle of the air outlet frame 210 and allowing the air outlet frame 210 to better fit with the panel, thereby improving the aesthetics of the product.

[0062] Furthermore, the movement direction of the movable portion 111 between the first and second positions forms an angle with the movement direction of the first driving portion 110 between the third and fourth positions. This enables bidirectional movement of the air outlet frame 210, expands the air delivery angle of the air outlet frame 210, and allows the air outlet frame 210 to better fit the panel, thereby improving the aesthetics of the product. For example, an air outlet is constructed on the shell of the air conditioner 200, and an air outlet grille is provided on the air outlet frame 210, at least part of the air outlet grille is opposite to the air outlet, and the movement direction of the movable part 111 between the first position and the second position is along the circumference of the shell, so that the movement of the movable part 111 drives the air outlet frame 210 to move, thereby adjusting the air supply angle of the air outlet frame 210; the movement direction of the first driving part 110 between the third position and the fourth position is along the direction of the air outlet frame 210 approaching or moving away from the shell, so that when the air outlet angle needs to be adjusted, the second driving part 120 is controlled to drive the first driving part 110, so that the first driving part 110 drives the air outlet frame 210 away from the shell, so as to further control the rotation of the air outlet frame 210, and after adjustment, the second driving part 120 is controlled to drive the first driving part 110, so that the first driving part 110 drives the air outlet frame 210 close to the shell, so that the air outlet frame 210 can better fit with the shell, thereby improving the aesthetics of the product.

[0063] Furthermore, if Figure 3 and Figure 4 As shown, the movable portion 111 is arc-shaped, wherein the movement direction of the movable portion 111 between the first position and the second position is along the circumference of the movable portion 111 (for details, please refer to Figure 3 The movement direction of the first driving part 110 between the third position and the fourth position is along the radial direction of the movable part 111 (see FIG. Figure 4 As shown in x2). In this way, during the movement of the movable portion 111, the movable portion 111 can be used to drive the air outlet frame 210 to rotate to adjust the air outlet angle. This structure can further avoid the limitation of the air outlet frame 210 driving dead angle and prevent the air outlet frame 210 from being restricted in its movement angle, thereby allowing the air outlet frame 210 to have a wider air supply range.

[0064] The movement direction of the first driving part 110 between the third position and the fourth position is set along the radial direction of the movable part 111. The second driving part 120 can be used to drive the air outlet frame 210 to form a linear motion, so that the air outlet frame 210 can better fit with the shell and improve the aesthetics of the product.

[0065] In one embodiment of the present invention, Figure 3 and Figure 6As shown, the movable portion 111 includes a first rack 1112, and the first driving device 112 includes a first driving member 1121 (such as a motor) and a first gear 1122 driven to rotate by the first driving member 1121. The first rack 1112 is engaged with the first gear 1122. The first driving member 1121 and the movable portion 111 are driven by the gears. On the one hand, the rack and pinion mechanism has high transmission efficiency, which can further improve the motion control accuracy of the air outlet frame 210 and prevent the air outlet frame 210 from jamming. On the other hand, the gear meshing transmission can improve the motion stability of the air outlet frame 210 and achieve a certain degree of vibration absorption and shock reduction effect, further improving the shaking problem of the air outlet frame 210.

[0066] In one embodiment of the present invention, Figure 6 As shown, the first drive unit 110 further includes a first box body 113. The first box body 113 has an accommodating cavity 115 with an opening at one end. At least a portion of the movable portion 111 and the first gear 1122 are located in the accommodating cavity 115. The connecting structure 1111 extends from the opening to the first box body 113. By encapsulating the movable portion 111 and the first gear 1122 using the first box body 113, the first drive unit 110 can be formed into a modular structure. On the one hand, the structure of the air outlet frame drive mechanism 100 is simpler, and the assembly steps are simplified, making the product assembly process simpler and more efficient. On the other hand, the protection effect of the meshing portion can be further improved to prevent the meshing portion from being stuck by foreign objects. The second drive unit 120 drives the modular first drive unit 110, making the drive simpler and more reliable. The meshing portion between the first gear 1122 and the first rack 1112 can be prevented from misaligning during movement, thereby improving the reliability of the first drive unit 110.

[0067] For example, the first box body 113 includes a first box cover 113a and a second box cover 113b, which are connected to each other and enclose a accommodating cavity 115 with an opening at one end. The first rack 1112 has a connecting portion, and the connecting portion has two opposite side surfaces. A tooth structure for engaging with the first gear 1122 is formed on one side of the connecting portion, and a connecting structure 1111 is provided on the other side of the connecting portion, wherein the tooth structure of the first rack 1112 extends into the accommodating cavity 115 from the opening and engages with the first gear 1122.

[0068] In certain embodiments, the first rack 1112 is arc-shaped and has opposing concave arc edges 11121 and convex arc edges 11122. One of the concave arc edges 11121 and convex arc edges 11122 is configured with a tooth structure suitable for meshing with the first gear 1122, and the other is configured with a connecting structure 1111. The arrangement of the connecting structure 1111 and the tooth structure relative to each other helps prevent interference with the movement of the first rack 1112 by the air outlet frame 210, thereby ensuring smooth and precise movement of the first rack 1112.

[0069] In a specific embodiment, the first rack 1112 is arc-shaped, and at least one side wall on the first box body 113 is a convex arc wall adapted to the first rack 1112. An extension portion is extended from at least one end of the convex arc wall to provide a movable space for the first rack 1112.

[0070] Furthermore, the first housing 113 has a through hole 1131, the first driving member 1121 is located outside the first housing 113, and the output shaft of the first driving member 1121 passes through the through hole 1131 and is connected to the first gear 1122. This makes it more convenient to assemble and repair the product and also helps dissipate heat from the first driving member 1121.

[0071] For example, the first box body 113 includes a first box cover 113a and a second box cover 113b, which are connected to each other and define a accommodating cavity 115 with an opening at one end. The first box cover 113a and the second box cover 113b are distributed up and down, wherein the upper one of the first box cover 113a and the second box cover 113b is provided with a through hole 1131, and the first driving member 1121 is provided on the upper one of the first box cover 113a and the second box cover 113b, and the output shaft of the first driving member 1121 passes through the through hole 1131 and is connected to the first gear 1122.

[0072] Furthermore, a first slide rail 116 is provided in the accommodating cavity 115, wherein a portion of the first rack 1112 is located in the first slide rail 116 and slides along the first slide rail 116. This can guide the first rack 1112 to make its movement more precise, thereby improving the movement accuracy of the first rack 1112. This further improves the accuracy of the air supply angle of the air outlet frame 210, and simultaneously achieves a sliding connection between the movable portion 111 and the first box body 113, thereby making the movement of the movable portion 111 more stable.

[0073] In some embodiments, the movable portion 111 further includes a first roller 1113, which is connected to the first rack 1112, and at least a portion of the first roller 1113 extends into the first slide rail 116. The first roller 1113 is slidably connected to the first slide rail 116 and guided by the first slide rail 116. On the one hand, the first roller 1113 reduces friction between the first rack 1112 and the first housing 113 during movement, thereby improving the smoothness and precision of the movement of the first rack 1112, reducing the driving force requirement for the first driving member 1121, reducing the operating power of the first driving member 1121, and extending the service life of the first driving member 1121. On the other hand, the first roller 1113 provides a certain support for the first driving portion 110, which helps reduce wear on the first rack 1112 and ensures the reliability and precision of the first driving portion 110.

[0074] For example, the first rack 1112 has a connecting portion, which has two opposite side surfaces. A tooth structure for engaging with the first gear 1122 is formed on one side of the connecting portion, and a connecting structure 1111 and a connecting shaft for connecting to the first roller 1113 are provided on the other side of the connecting portion. The first roller 1113 is passed through the connecting shaft.

[0075] Furthermore, a plurality of first rollers 1113 are provided on the connecting portion, and the plurality of first rollers 1113 are provided on the connecting portion at intervals.

[0076] In some embodiments, the first roller 1113 is a metal wheel or a non-metal wheel.

[0077] In one embodiment of the present invention, Figure 4 and Figure 7 As shown, the second driving portion 120 includes a second rack 121 , a second gear 122 and a second driving member 123 .

[0078] The second rack 121 has a connecting portion 1, which is connected to the first driving portion 110. The second gear 122 is engaged with the second rack 121. The second gear 122 rotates to drive the second rack 121 to move between the third position and the fourth position. The second driving member 123 (such as a motor) is connected to the second gear 122, and the second driving member 123 is configured to drive the second gear 122 to rotate. The second driving part 120 is provided with a second rack 121, and the second rack 121 is meshed with the second gear 122, so that the second driving member 123 (such as a motor) and the second rack 121 are transmitted through the gear. On the one hand, the rack and pinion mechanism has high transmission efficiency, which can further improve the motion control accuracy of the second driving part 120, thereby improving the motion control accuracy of the air outlet frame 210 and preventing the air outlet frame 210 from being stuck. On the other hand, through the tooth meshing transmission, the movement stability of the second driving part 120 can be improved, and it can play a vibration absorption and shock reduction effect to a certain extent, thereby avoiding the first driving part 110 from being dislocated during the movement, thereby improving the driving reliability of the first driving part 110.

[0079] In one embodiment of the present invention, Figure 7 As shown, the second drive unit 120 further includes a protective cover 124, and the second gear 122 and at least a portion of the second rack 121 are located within the protective cover 124. This further enhances the protection of the first gear 1122 and the first rack 1112, preventing foreign objects from getting stuck at the meshing portion, thereby improving product reliability. Furthermore, the protective cover 124 creates a certain distance between the meshing portion of the first drive unit 110 and the second drive unit 120, preventing interference between the movement of the movable portion 111 of the first drive unit 110 and the meshing portion of the second drive unit 120, thereby ensuring the movement reliability of the first drive unit 110 and the second drive unit 120.

[0080] Furthermore, the protective cover 124 has a top wall 1241, a straight wall 1242, and a curved wall 1243. The straight wall 1242 and the curved wall 1243 are spaced apart, and the top wall 1241 transitions between the straight wall and the curved wall 1243. The curved wall 1243 and a portion of the top wall 1241 enclose a gear accommodating space 1244 suitable for accommodating the second gear 122. The straight wall and another portion of the top wall 1241 enclose a rack accommodating space 1245 suitable for accommodating the second rack 121. The gear accommodating space 1244 and the rack accommodating space 1245 are connected, so that a portion of the second gear 122 meshes with the second rack 121 at the connection between the gear accommodating space 1244 and the rack accommodating space 1245. In this way, the protective cover 124 can better adapt to the gear and rack structure, reduce the space occupied by the protective cover 124, achieve a compact layout, and facilitate miniaturization of the product.

[0081] Furthermore, if Figure 4 and Figure 7 As shown, the end of the curved wall 1243 extends outward to form an extension wall 1246. The extension wall 1246 is spaced apart from and opposite to the straight wall 1242. A guide slot 1247 is defined between the extension wall 1246 and the straight wall 1242. At least a portion of the second rack 121 extends into and is guided by the guide slot 1247. This allows for more precise movement of the second rack 121, improving the movement accuracy of the first drive unit 110, thereby further enhancing the fit between the air outlet frame 210 and the panel.

[0082] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, the first driving unit 110 includes a first housing 113, with at least a portion of the movable portion 111 and at least a portion of the first driving device 112 housed within the first housing 113. A slot 1132 is provided on the outer wall of the first housing 113, and the connecting portion 1 includes a plug-in block 11 that fits within the slot 1132. The plug-in block 11 extends into the slot 1132. The first driving unit 110 is pluggably mated with the second rack 121 of the second driving unit 120. This facilitates assembly of the first driving unit 110 and the second driving unit 120, and provides a highly reliable connection between the first driving unit 110 and the second rack 121.

[0083] In one embodiment of the present invention, Figure 7 As shown, the second driving unit 120 further includes an upper cover 125 and a lower cover 126. The upper cover 125 and the lower cover 126 together define a receiving space 1271 having a relief opening 1272. The first driving unit 110 extends from the relief opening 1272 into the receiving space 1271. When the first driving unit 110 is in the third position, the first box body 113 fits with the upper cover 125 and / or the lower cover 126. When the first driving unit 110 is in the fourth position, the first box body 113 extends from the relief opening 1272 into the receiving space 1271. By encapsulating the first drive unit 110 using the upper cover 125 and the lower cover 126, the wind frame drive mechanism 100 can be formed into a modular structure as a whole. The upper cover 125 and the lower cover 126 have a simple structure and are easy to assemble, thereby making the assembly flow of the product simpler and more efficient. On the other hand, the upper cover 125 and the lower cover 126 are used to further enhance the protection effect of the first drive unit 110, the second rack 121 and the second gear 122, thereby enhancing the driving reliability of the first drive unit 110 and the second drive unit 120.

[0084] For example, a hole for the output shaft of the second driving member 123 to pass through is defined on the lower cover 126 , so that the second driving member 123 extends from the hole into the accommodating space 1271 and the output shaft of the second driving member 123 is connected to the second gear 122 .

[0085] The avoidance opening 1272 is suitable for avoiding the first driving member 1121, so that at least part of the first driving member 1121 extends out of the upper cover 125 from the avoidance opening 1272. In this way, the first driving member 1121 and the second driving member 123 are respectively located on opposite sides and separated by the upper cover 125 and the lower cover 126, thereby avoiding mutual interference between the two driving members and facilitating heat dissipation of the two driving members.

[0086] Further, if Figure 7 As shown, a second slide groove 1251 is constructed on the inner top surface of the upper cover 125, and the second driving part 120 also includes a second roller 1281. The second roller 1281 is connected to the first box body 113, and at least part of the second roller 1281 extends into the second slide groove 1251. The second roller 1281 is slidingly connected to the second slide groove 1251 and is guided by the second slide groove 1251. The second roller 1281 is used to reduce the friction between the first driving part 110 and the upper cover 125 during movement, thereby improving the smoothness and accuracy of the movement of the first driving part 110, reducing the driving force requirements of the second driving member 123, reducing the operating power of the second driving member 123, and extending the service life of the second driving member 123.

[0087] A third slide groove 1261 is configured on the inner bottom surface of the lower cover 126. The second drive unit 120 also includes a third roller 1282. The third roller 1282 is connected to the first housing 113, and at least a portion of the third roller 1282 extends into the third slide groove. The third roller 1282 is slidably connected to and guided by the third slide groove 1261. The third roller 1282 reduces friction between the first drive unit 110 and the lower cover 126 during movement, thereby improving the smoothness and precision of the movement of the first drive unit 110, reducing the driving force required by the second drive member 123, reducing the operating power of the second drive member 123, and extending the service life of the second drive member 123. Furthermore, the third roller 1282 provides a certain degree of support for the first drive unit 110, thereby reducing wear on the first drive unit 110 and ensuring the reliability and precision of the first drive unit 110.

[0088] The embodiment of the second aspect of the present invention provides an air conditioner 200, such as Figure 9 and Figure 10 As shown, the air conditioner 200 includes: an air outlet frame 210; and an air outlet frame driving mechanism 100 such as any of the above technical solutions, wherein the air outlet frame 210 is connected to the connecting structure 1111 of the air outlet frame driving mechanism 100.

[0090] In the above technical solution, the connection structure 1111 includes ribs, and the air outlet frame 210 is provided with plug holes that match the ribs, and the ribs are plugged into the plug holes. In this way, the connection of the air outlet frame 210 is more reliable and easy to assemble.

[0091] In certain embodiments, as Figure 8 As shown, the air conditioner 200 has at least two air outlet frame driving mechanisms 100 , and the at least two air outlet frame driving mechanisms 100 are distributed along the height direction of the air outlet frame 210 , so that the control of the air outlet frame 210 is more precise.

[0092] In some embodiments, the air outlet frame 210 is arc-shaped, which is beneficial to expanding the air outlet angle of the air outlet frame 210 and improving the user experience of the product.

[0093] In some embodiments, the air conditioner 200 is a cabinet air conditioner.

[0094] In summary, the air outlet frame driving mechanism and air conditioner provided by the present invention are connected to the movable part, and the first driving device drives the movable part to move between the first position and the second position, that is, the air outlet frame moves with the movable part between the first position and the second position, and the movable amount of the air outlet frame is released through the movable part, so that the air outlet frame has a larger air supply angle, thereby improving the usage experience of the product, and the second driving part drives the first driving part to move between the third position and the fourth position, that is, the second driving part drives the first driving part and the air outlet frame to move between the third position and the fourth position. Compared with the existing solution in which the motion mechanism drives the air outlet frame to move in one direction, this solution utilizes the first driving part and the second driving part to realize two-way movement of the air outlet frame, thereby expanding the air supply angle of the air outlet frame and making the air outlet frame better fit with the panel, thereby improving the aesthetics of the product.
