[0001] The present invention relates to the technical field of air conditioning, and in particular to a driving component and an air conditioner. Background Art

[0002] As people's living standards continue to improve, air conditioners have become an indispensable household appliance in the home. At present, air conditioners are usually provided with a rotatable air guide plate, and a drive box is used to drive the air guide plate to rotate so as to guide the air flow of the air conditioner, thereby realizing the function of adjusting the wind direction. Currently, a transmission structure (such as a matching structure of a socket and a latch) is generally provided between the current drive box and the air guide plate, and the drive box is connected to the air guide plate through the transmission structure to ensure the stability of the transmission process. However, in this way, the number of parts is large, the disassembly and assembly process is complicated, the disassembly and assembly efficiency is low, it is not convenient for maintenance and maintenance, and the material cost is increased, and the economic benefit is reduced. Summary of the invention

[0003] The problem solved by the present invention is how to reduce the number of parts while ensuring transmission stability, simplify the disassembly and assembly process, improve the disassembly and assembly efficiency, reduce material costs, and improve economic benefits.

[0004] To solve the above problems, the technical solution of the present invention is achieved as follows:

[0005] In a first aspect, the present invention provides a driving assembly, including a driving box, a transmission structure and a transmission rod, the driving box including a main body section and an extension section connected to each other, the transmission structure installed in the main body section, the output end of the transmission structure linked with the transmission rod, the transmission rod movably installed in the extension section, and the transmission rod can extend or retract into the extension section along its extension direction. Compared with the prior art, the driving assembly provided by the present invention adopts a transmission structure installed in the main body section and a transmission rod movably installed in the extension section, so it can reduce the number of parts while ensuring transmission stability, simplify the disassembly and assembly process, improve the disassembly and assembly efficiency, and reduce material costs, thereby improving economic benefits.

[0006] Furthermore, the transmission structure is provided with a matching hole, the transmission rod is movably connected to the matching hole, and the transmission rod can slide relative to the matching hole along its extension direction to extend or retract the extension section. This facilitates the disassembly and assembly of the drive assembly and the connection between the transmission rod and the air guide plate. The transmission structure can drive the transmission rod to rotate when the transmission rod slides to any position relative to the transmission structure to ensure the stability of the transmission process.

[0007] Furthermore, the extension section is provided with an escape opening, which is used to make way for the transmission rod so as to facilitate the movement of the transmission rod. The user can move the transmission rod through the escape opening so that the transmission rod slides relative to the matching hole, thereby extending or retracting the transmission rod into the extension section, which is convenient and practical.

[0008] Further, a rotation-preventing inner wall is provided in cooperation with the hole, and the transmission rod is provided with a abutting surface, and the rotation-preventing inner wall cooperates with the abutting surface to prevent the transmission rod from rotating relative to the mating hole and ensure the stability of the transmission structure driving the transmission rod to rotate.

The limiting ring is arranged between the sleeve and the elastic member. The sleeve is used to stop the limiting ring. The sleeve is used to reduce the friction between the transmission rod and the extending section to ensure that the transmission rod can rotate stably in the extending section. The sleeve is also used to limit the transmission rod to prevent the transmission rod from being misaligned or radially jumping during rotation. The sleeve is also used to prevent the limiting ring from protruding out of the opening, thereby preventing the transmission rod from disengaging from the mating hole and ensuring the stability of the cooperation between the transmission structure and the transmission rod.

[0011] Further, the main body section includes a base and a top cover. The top cover covers the base and is detachably connected to the base.

Detailed implementation mode

[0024] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0025] First embodiment

[0026] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a driving assembly 120 for driving the air deflector to realize the function of adjusting the wind direction. It can reduce the number of parts while ensuring the transmission stability, simplify the disassembly and assembly process, improve the disassembly and assembly efficiency, and reduce the material cost, thereby improving the economic benefits.

[0027] It should be noted that the driving assembly 120 is applied to the air conditioner 100. The air conditioner 100 is hung on the wall and can blow hot air or cold air into the room to achieve the functions of heating or cooling. Specifically, the air conditioner 100 includes a middle frame 110, a driving assembly 120, an air deflector 130, a blower (not shown in the figure), and a heat exchanger (not shown in the figure). Among them, the driving assembly 120, the air deflector 130, the blower, and the heat exchanger are all installed in the middle frame 110. The blower is used to generate negative pressure to drive the air flow and form an outlet air flow. The heat exchanger is used to exchange heat with the outlet air flow so that the outlet air flow has the function of heating or cooling. Specifically, the driving assembly 120 is connected to the air deflector 130. The driving assembly 120 is used to drive the air deflector 130 to rotate, and the air deflector 130 is used to guide the outlet air flow to realize the function of adjusting the wind direction.

[0028] Please refer to Figures 3 to 7, the driving assembly 120 includes a driving box 121, a transmission structure 122, and a transmission rod 123. Among them, the transmission structure 122 is installed inside the driving box 121. The output end of the transmission structure 122 is linked with the transmission rod 123, and the transmission structure 122 can drive the transmission rod 123 to rotate. Specifically, the transmission rod 123 is movably installed inside the driving box 121. The transmission rod 123 can extend or retract into the driving box 121 along its extending direction, and the driving box 121 can limit the transmission rod 123.

[0029] The driving box 121 includes a main body section 1211 and an extension section 1212 that are connected to each other. The transmission structure 122 is installed inside the main body section 1211, and the transmission rod 123 is movably installed inside the extension section 1212. The transmission rod 123 can extend or retract into the extension section 1212 along its extending direction. The transmission rod 123 extending out of the extension section 1212 is connected to the air deflector 130 to drive the air deflector 130 to rotate, so as to realize the function of adjusting the air direction of the air conditioner 100. In this way, since the extension section 1212 can limit the transmission rod 123 and ensure the stability of the rotation of the transmission rod 123, the transmission rod 123 does not need to be connected to the air deflector 130 through the transmission structure in the prior art. Instead, the transmission rod 123 is directly connected to the air deflector 130, that is, the additional connection structure between the outside of the driving box and the air deflector in the prior art is eliminated. While ensuring the transmission stability, the number of parts is reduced, the disassembly and assembly process is simplified, the disassembly and assembly efficiency is improved, the material cost is reduced, and the economic benefit is improved.

[0030] In this embodiment, the main body section 1211 and the extension section 1212 are arranged in an L shape, that is, the main body section 1211 and the extension section 1212 are perpendicular to each other, so as to minimize the occupied space of the driving assembly 120 while ensuring the transmission stability and facilitate disassembly and assembly.

[0031] The middle frame 110 includes an end plate 111, a connecting plate 112 and a limiting plate 113. The end plate 111 and the limiting plate 113 are arranged at intervals, the end plate 111 is connected to the limiting plate 113 through the connecting plate 112, a through hole 1131 is formed in the limiting plate 113, and the air guide plate 130 is rotatably installed on one side of the limiting plate 113 away from the end plate 111. In this embodiment, the end plate 111, the connecting plate 112 and the limiting plate 113 are integrally formed to improve the connection strength. Specifically, the main body section 1211 of the driving assembly 120 is connected to the end plate 111, the extending section 1212 of the driving assembly 120 abuts against the limiting plate 113, and the end plate 111 and the limiting plate 113 act together to support and position the driving box 121 to prevent the driving box 121 from displacing relative to the middle frame 110. The transmission rod 123 is selectively arranged through the through hole 1131. When the transmission rod 123 extends out of the driving box 121 along its extending direction, a part of the transmission rod 123 extends out of the extending section 1212 and is arranged through the through hole 1131, and the transmission rod 123 passing through the through hole 1131 is connected to the air guide plate 130 to drive the air guide plate 130 to rotate, so as to realize the function of adjusting the air direction of the air conditioner 100; when the transmission rod 123 retracts into the driving box 121 along its extending direction, the transmission rod 123 retracts out of the through hole 1131 and is completely hidden in the extending section 1212 to facilitate the disassembly and assembly of the driving assembly 120.

[0032] It should be noted that the transmission structure 122 is provided with a mating hole 1221, the transmission rod 123 is movably connected to the mating hole 1221, the mating hole 1221 is coaxially arranged with the transmission rod 123, and the transmission rod 123 can slide relative to the mating hole 1221 along its extending direction to extend out or retract into the extending section 1212, so as to facilitate the disassembly and assembly of the driving assembly 120 and the connection between the transmission rod 123 and the air guide plate 130. The transmission structure 122 can drive the transmission rod 123 to rotate when the transmission rod 123 slides to any position relative to the transmission structure 122 to ensure the stability of the transmission process.

[0033] Furthermore, the mating hole 1221 is provided with an anti-rotation inner wall 1222, and the transmission rod 123 is provided with an abutting surface 1231. The anti-rotation inner wall 1222 cooperates with the abutting surface 1231 to prevent the transmission rod 123 from rotating relative to the mating hole 1221 and ensure the stability of the transmission structure 122 driving the transmission rod 123 to rotate.

[0034] In this embodiment, the cross section of the mating hole 1221 is hexagonal, and the shape of the transmission rod 123 matches the shape of the mating hole 1221 to ensure the stability of the transmission process, but it is not limited to this. In other embodiments, the cross section of the mating hole 1221 can be rectangular or semi-circular, and the shapes of the mating hole 1221 and the transmission rod 123 are not specifically limited.

[0035] In this embodiment, the extension section 1212 is provided with an avoidance opening 1213, which is used to make way for the transmission rod 123 to facilitate the movement of the transmission rod 123. The user can move the transmission rod 123 through the avoidance opening 1213 to make the transmission rod 123 slide relative to the matching hole 1221, thereby extending the transmission rod 123 or retracting it into the extension section 1212, which is convenient and practical.

[0036] It should be noted that the drive assembly 120 also includes an elastic member 124, a limiting ring 1232 is provided on the circumference of the transmission rod 123, the elastic member 124 is sleeved outside the transmission rod 123, one end of the elastic member 124 abuts against the limiting ring 1232, and the other end abuts against the transmission structure 122, the elastic member 124 is always in a compressed state, and the elastic member 124 can apply elastic force to the limiting ring 1232, so that the entire transmission rod 123 has a tendency to slide outward from the matching hole 1221. Specifically, the elastic member 124 is connected between the transmission structure 122 and the transmission rod 123, and the transmission rod 123 can overcome the elastic force of the elastic member 124 under the action of an external force and slide relative to the transmission structure 122, and retract into the matching hole 1221, and the transmission rod 123 can also slide back relative to the transmission structure 122 under the action of the elastic force of the elastic member 124, and extend outward from the matching hole 1221. In addition, the limiting ring 1232 is arranged in the avoidance opening 1213, and the user can drive the entire transmission rod 123 to slide relative to the matching hole 1221 by turning the limiting ring 1232, thereby achieving a labor-saving effect and facilitating operation.

[0037] Furthermore, the drive assembly 120 also includes a sleeve 125. The extension section 1212 is provided with an opening 1214, and the sleeve 125 is installed in the opening 1214 and sleeved outside the transmission rod 123. The sleeve 125 is used to reduce the friction between the transmission rod 123 and the extension section 1212 to ensure that the transmission rod 123 can rotate stably in the extension section 1212. The sleeve 125 is also used to limit the transmission rod 123 to prevent the transmission rod 123 from being dislocated or radially jumping during the rotation process. Specifically, the opening 1214 is arranged on the end wall of the extension section 1212 away from the main section 1211, and the limiting ring 1232 is arranged between the sleeve 125 and the elastic member 124. The sleeve 125 is used to stop the limiting ring 1232 to prevent the limiting ring 1232 from extending out of the opening 1214, thereby preventing the transmission rod 123 from escaping from the matching hole 1221, thereby ensuring the stability of the matching between the transmission structure 122 and the transmission rod 123.

[0038] The main body section 1211 includes a base 1215 and a top cover 1216. The top cover 1216 is disposed on the base 1215 and is detachably connected to the base 1215. The transmission structure 122 is disposed between the top cover 1216 and the base 1215. The top cover 1216 and the base 1215 cooperate to limit the transmission structure 122. Specifically, the base 1215 is connected to the end plate 111, and the base 1215 is connected to the extension section 1212. By fixing the base 1215 on the end plate 111, the top cover 1216 and the extension section 1212 are fixed at the same time, which is stable and reliable. In this embodiment, the base 1215 and the extension section 1212 are integrally formed to improve the connection strength.

[0039] It should be noted that the drive assembly 120 further includes a drive motor 126. The drive motor 126 is installed on the top cover 1216 and is connected to the input end of the transmission structure 122. The input end of the transmission structure 122 is connected to the drive motor 126, and the output end of the transmission structure 122 is connected to the transmission rod 123. The drive motor 126 can drive the transmission rod 123 to rotate through the transmission structure 122, thereby driving the air deflector 130 to rotate, and further realizing the function of adjusting the air direction of the air conditioner 100.

[0040] In this embodiment, the drive motor 126 is connected to the top cover 1216 by screws, the top cover 1216 is connected to the base 1215 by screws, and the base 1215 is connected to the end plate 111 by screws, but it is not limited thereto. In other embodiments, the drive motor 126 can be bonded or snapped onto the top cover 1216; the top cover 1216 can be snapped onto the base 1215; the base 1215 can be snapped onto the end plate 111 or riveted to the end plate 111; the connection methods of the drive motor 126, the top cover 1216, the base 1215, and the end plate 111 are not specifically limited.

[0041] The transmission structure 122 includes a driving gear 1223, a first transmission gear 1224, a second transmission gear 1225, and a driven gear 1226. The driving gear 1223, the first transmission gear 1224, the second transmission gear 1225, and the driven gear 1226 are all rotatably mounted in the driving box 121. The output shaft of the driving motor 126 is connected to the driving gear 1223, and the driving motor 126 is used to drive the driving gear 1223 to rotate. The driving gear 1223 meshes with the first transmission gear 1224. The first transmission gear 1224 is sleeved outside the second transmission gear 1225 and cooperates with the second transmission gear 1225. The driving gear 1223 can drive the second transmission gear 1225 to rotate through the first transmission gear 1224. The second transmission gear 1225 meshes with the driven gear 1226. The driven gear 1226 is connected to the transmission rod 123 through an elastic member 124. The second transmission gear 1225 can drive the transmission rod 123 to rotate through the driven gear 1226, thereby driving the air deflector 130 to rotate. Specifically, a mating hole 1221 is formed in the driven gear 1226. The elastic member 124 is sleeved outside the transmission rod 123. One end of the elastic member 124 abuts against the limiting ring 1232, and the other end abuts against the driven gear 1226.

[0042] In this embodiment, a safety protection structure is provided between the first transmission gear 1224 and the second transmission gear 1225. This safety protection structure can ensure the transmission efficiency between the first transmission gear 1224 and the second transmission gear 1225 under normal operation conditions, and can also cause the first transmission gear 1224 to slip relative to the second transmission gear 1225 when a sudden force occurs in the transmission structure 122, so as to prevent tooth slipping between the driving gear 1223 and the first transmission gear 1224 or between the second transmission gear 1225 and the driven gear 1226, extend the service life of the transmission structure 122, and improve safety.

[0043] In this embodiment, the air deflector 130 is disposed on the side of the limiting plate 113 away from the end plate 111. The air deflector 130 is provided with an assembly hole 131. The position of the assembly hole 131 corresponds to the position of the through hole 1131 on the limiting plate 113. The transmission rod 123 is disposed through the through hole 1131 and cooperates with the assembly hole 131. Specifically, the assembly hole 131 is coaxially arranged with the transmission rod 123. The transmission rod 123 can slide relative to the assembly hole 131 along its extending direction to extend into or retract from the air deflector 130, so as to facilitate the disassembly and assembly of the air deflector 130 and the connection between the transmission rod 123 and the air deflector 130. When the transmission rod 123 extends into the assembly hole 131 of the air deflector 130, the driving assembly 120 can drive the air deflector 130 to rotate through the cooperation between the transmission rod 123 and the assembly hole 131, so as to realize the function of adjusting the air direction of the air conditioner 100.

[0044] Further, the assembly hole 131 is provided with an anti-rotation inner wall 132, and the transmission rod 123 is provided with a mating surface 1233. The anti-rotation inner wall 132 cooperates with the mating surface 1233 to prevent the transmission rod 123 from rotating relative to the assembly hole 131, ensuring the stability of the transmission rod 123 driving the air deflector 130 to rotate.

[0045] In this embodiment, the cross-section of the assembly hole 131 is hexagonal, and the shape of the transmission rod 123 matches the shape of the assembly hole 131 to ensure the stability of the transmission process. However, it is not limited thereto. In other embodiments, the cross-section of the assembly hole 131 can be rectangular or semi-circular, and the shapes of the assembly hole 131 and the transmission rod 123 are not specifically limited.

[0046] It should be noted that the transmission rod 123 includes a first rod section 1234, a second rod section 1235, and a third rod section 1236 connected in sequence. In this embodiment, the first rod section 1234, the second rod section 1235, and the third rod section 1236 are integrally formed to improve the connection strength. Among them, the abutting surface 1231 is provided on the first rod section 1234, and the first rod section 1234 cooperates with the mating hole 1221 of the driven gear 1226; the limiting ring 1232 is provided between the first rod section 1234 and the second rod section 1235, and the elastic member 124 is sleeved outside the first rod section 1234 and abuts against the limiting ring 1232. The second rod section 1235 cooperates with the sleeve 125; the mating surface 1233 is provided on the third rod section 1236, and the third rod section 1236 cooperates with the assembly hole 131 of the air deflector 130.

[0047] During the installation of the drive assembly 120, first, an external force is used to drive the drive box 121 to move, so that the limiting plate 113 overcomes the elastic force of the elastic member 124 and presses the transmission rod 123 into the drive box 121; when the drive box 121 is assembled in place, the extension section 1212 abuts against the limiting plate 113, and the opening 1214 on the extension section 1212 is aligned with the through hole 1131 of the limiting plate 113. At this time, the limiting plate 113 no longer applies an abutting force to the transmission rod 123, and the transmission rod 123 resets under the elastic force of the elastic member 124 and passes through the through hole 1131; subsequently, the drive box 121 is connected to the end plate 111 with screws to realize the fixing function of the drive box 121 and complete the installation of the drive assembly 120.

[0048] During the installation of the air deflector 130, first, the limiting ring 1232 is toggled through the avoidance opening 1213 so that the transmission rod 123 retracts into the fitting hole 1221 against the elastic force of the elastic member 124, thereby causing the transmission rod 123 to retract into the through hole 1131 of the limiting plate 113; subsequently, the air deflector 130 is installed into the middle frame 110 and is disposed on the side of the limiting plate 113 away from the end plate 111, and the fitting hole 131 of the air deflector 130 is aligned with the through hole 1131 of the limiting plate 113. At this time, since the transmission rod 123 is in the retracted state, the transmission rod 123 will not interfere with the installation of the air deflector 130; then the limiting ring 1232 is released, and the transmission rod 123 is reset under the elastic force of the elastic member 124 and passes through the through hole 1131 and extends into the fitting hole 131 to realize the connection between the transmission rod 123 and the air deflector 130, completing the installation of the air deflector 130.

[0049] In the driving assembly 120 described in the embodiment of the present invention, the middle frame 110 includes an end plate 111, a connecting plate 112, and a limiting plate 113. The end plate 111 and the limiting plate 113 are spaced apart. The end plate 111 is connected to the limiting plate 113 through the connecting plate 112. The limiting plate 113 is provided with a through hole 1131; the driving assembly 120 includes a driving box 121, a transmission structure 122, and a transmission rod 123. The driving box 121 includes a main body section 1211 and an extension section 1212 that are connected to each other.
