Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an air guide mechanism and an air conditioning unit. Background Technology

[0002] As part of the air conditioning system, the structural design of the air guide mechanism affects the air outlet effect of the air duct components, the sweeping angle of the air guide plate, and the comfort of the sweeping.

[0003] Currently, there are two main assembly methods for commonly used air guide mechanisms:

[0004] 1. The air guide plate is connected to the connecting rod via the crankshaft, and then the connecting rod is driven by the stepper motor to realize the opening and closing state of the air guide plate, thereby achieving the purpose of air guiding and sweeping. However, when multiple air guide plates need to be connected, this assembly method will result in the connecting rod cantilever being too long, making it impossible to realize the real-time movement of multiple air guide plates, resulting in motion delay. In addition, this assembly method has many parts, high mold costs, and complicated processing procedures.

[0005] 2. Connect multiple air guide vanes with connecting rods, then assemble a crankshaft onto any one of the air guide vanes, and drive the movement of the air guide vanes with a stepper motor to achieve the overall movement of the air guide vanes. Although this assembly method can achieve the movement of multiple air guide vanes, it is difficult to guarantee the real-time movement of multiple air guide vanes due to factors such as assembly gaps and processing errors, resulting in a movement delay.

[0006] It is evident that the driving method of the air guide mechanism in the existing technology that drives the air guide plate will cause a delay in the movement of the air guide plate. Summary of the Invention

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] This invention provides an air guiding mechanism, please refer to... Figures 1 to 9 The air guiding mechanism includes a mounting base 10, a drive assembly, and an air guide plate 40. The mounting base 10 is mounted on the air outlet frame 90. The drive assembly includes a drive gear 30 and a transmission component 20. The drive gear 30 is rotatably mounted around its central axis and connected to the transmission component 20. The transmission component 20 is rotatably mounted on the mounting base 10. The transmission component 20 is connected to the air guide plate 40 so that the drive gear 30 drives the air guide plate 40 to rotate through the transmission component 20, thereby opening and closing the air guide plate 40 or performing air sweeping. The air guiding mechanism of this application uses gear transmission. Compared with the linkage transmission in the prior art, on the one hand, the air guiding mechanism of this application solves the problem of time delay in the movement of the air guide plate caused by the driving method of the air guiding mechanism in the prior art, and can ensure the stability of the air guide plate movement; on the other hand, the drive assembly of the air guiding mechanism of this application is easier to disassemble and assemble.

[0035] In this embodiment, the transmission component 20 includes a first transmission component 21, a second transmission component 22, and a third transmission component 23. The first transmission component 21 is connected to the drive gear 30 and is rotatably mounted on the mounting base 10; the second transmission component 22 is connected to the first transmission component 21; and the third transmission component 23 is connected to the second transmission component 22 and is connected to the air guide plate 40.

[0036] Specifically, such as Figure 6 As shown, the first transmission component 21 has a connecting hole 211, and the second transmission component 22 has a connecting post 221, which is used to pass through the connecting hole 211. The connecting post 221 has a recessed groove 222 on its outer peripheral wall, and a protrusion 212 protrudes from the wall of the connecting hole 211. Both the groove 222 and the protrusion 212 extend along the extending direction of the connecting post 221. The protrusion 212 is disposed within the groove 222 and slidably disposed along the groove 222. Thus, when the connecting post 221 is... When the protrusion 212 is inserted into or removed from the connecting hole 211, it can slide along the slot 222 to realize the assembly and disassembly of the first transmission member 21 and the second transmission member 22. Furthermore, when the protrusion 212 is located in the slot 222, the first transmission member 21 and the second transmission member 22 can be relatively fixed in the circumferential direction of the connecting post 221, thereby ensuring the stability between the first transmission member 21 and the second transmission member 22 when the first transmission member 21 drives the second transmission member 22 to rotate.

[0037] Specifically, the slot 222 has a first end close to the main body of the first transmission member 21 and a second end away from the main body of the first transmission member 21. The first end of the slot 222 extends to the end of the connecting post 221. The slot wall of the slot 222 includes a first slot wall 223 and a second slot wall 224 arranged at an angle. The first slot wall 223 is a plane. From the first end to the second end of the slot 222, the intersection line of the first slot wall 223 and the second slot wall 224 gradually approaches the outer peripheral wall of the connecting post 221 until it extends to the outer peripheral wall of the connecting post 221. The second slot wall 224 is a curved surface so that the protrusion 212 slides along the second slot wall 224. Optionally, the second slot wall 224 is a smooth curved surface.

[0038] It should be noted that the included angle between the first groove wall 223 and the second groove wall 224 refers to the included angle between the line of intersection of the first groove wall 223 and the end face of the connecting post 221 and the line of intersection of the second groove wall 224 and the end face of the connecting post 221; wherein, the end face of the connecting post 221 here refers to the end face of the connecting post 221 to which the first end of the slot 222 extends. Figure 6 The end face 225 is the end face of the connecting post 221 mentioned here. Optionally, the included angle between the first groove wall 223 and the second groove wall 224 is 90 degrees.

[0039] It should be noted that if Figure 7 As shown, the protrusion 212 has a first wall surface 2121 and a second wall surface 2122 arranged at an included angle. The first wall surface 2121 and the second wall surface 2122 are respectively adapted to the first groove wall 223 and the second groove wall 224. That is, the first wall surface 2121 is a plane and the second wall surface 2122 is a curved surface, so that the first wall surface 2121 contacts or is in clearance fit with the first groove wall 223, and the second wall surface 2122 contacts or is in clearance fit with the second groove wall 224. The included angle between the first wall surface 2121 and the second wall surface 2122 is equal to the included angle between the first groove wall 223 and the second groove wall 224. The structural arrangement of the slot 222 and the protrusion 212 of this application makes the assembly of the first transmission member 21 and the second transmission member 22 more convenient.

[0040] Optionally, there are multiple slots 222 and multiple protrusions 212, with multiple slots 222 spaced apart circumferentially along the connecting post 221; the multiple slots 222 and multiple protrusions 212 are arranged in a one-to-one correspondence.

[0041] Specifically, the mounting base 10 has a stepped hole 15, and a flange 213 is provided on the outer periphery of the first transmission member 21. The first transmission member 21 is rotatably inserted into the stepped hole 15. The flange 213 abuts against the step of the stepped hole 15, and the outer peripheral surface of the flange 213 contacts or is clearance-fitted with the hole wall of the stepped hole 15 so that the hole wall and the step of the stepped hole 15 circumferentially limit the flange 213.

[0042] Optionally, the first transmission component 21 is an injection molded part; lubricating oil is filled between the outer peripheral surface of the flange 213 and the hole wall of the stepped hole 15 to reduce the friction between the outer peripheral surface of the flange 213 and the hole wall of the stepped hole 15; wherein, the lubricating oil can be silicone grease.

[0043] Specifically, such as Figure 8 As shown, the third transmission component 23 includes a transmission body 231 and a first engaging portion 232. The first engaging portion 232 is disposed on the transmission body 231. The second transmission component 22 has a first engaging hole, and the first engaging portion 232 is engaged in the first engaging hole so that the second transmission component 22 and the third transmission component 23 are engaged.

[0044] Specifically, the third transmission component 23 also includes a second engaging portion 233, which is disposed on the transmission body 231. The air guide plate 40 has a second engaging hole 41, and the second engaging portion 233 is engaged in the second engaging hole 41 so that the third transmission component 23 and the air guide plate 40 are engaged.

[0045] In this embodiment, there are multiple drive components and multiple air guide plates 40, arranged one-to-one to drive the corresponding air guide plate 40 to rotate. The air guiding mechanism also includes a transmission gear set 50, which includes one or more transmission gears 51 meshing sequentially. The multiple drive components are arranged in a preset order, and a transmission gear set 50 is provided between the drive gears 30 of two adjacent drive components. The drive gears 30 of two adjacent drive components mesh with the transmission gears 51 of the transmission gear set 50 between them, so that the drive gears 30 of two adjacent drive components can be transmitted through the meshing of the transmission gear set 50 between them. That is, when the drive gear 30 of one of the multiple drive components rotates as the driving gear, it will drive the drive gears 30 of the other drive components to rotate as driven gears, so that the drive gears 30 of the multiple drive components rotate synchronously, thereby driving the multiple air guide plates 40 to rotate synchronously. The air guide mechanism of this application adopts a gear meshing transmission method, which can achieve high assembly accuracy and assembly efficiency, thereby ensuring high transmission accuracy. This ensures the synchronization and stability of the rotation of multiple air guide plates 40, solves the problem that the air guide mechanism in the prior art is difficult to guarantee the synchronization of the movement of multiple air guide plates, and reduces the vibration problem when the air guide plates rotate.

[0046] Specifically, when the transmission gear set 50 between the drive gears 30 of two adjacent drive components includes a transmission gear 51, the drive gears 30 of the two adjacent drive components mesh with the transmission gear set 50 between them; when the transmission gear set 50 between the drive gears 30 of two adjacent drive components includes multiple sequentially meshing transmission gears 51, according to the meshing sequence of the multiple transmission gears 51, the multiple transmission gears 51 include two end transmission gears located at two end positions, then the drive gears 30 of the two adjacent drive components mesh with the two end transmission gears of the transmission gear set 50 between them respectively.

[0047] Specifically, the air guide mechanism also includes a power component 60. The output of the power component 60 is connected to the drive gear 30 of one of the multiple drive components to drive the drive gear 30 to rotate, thereby causing the drive gear 30 to drive the drive gears 30 of the other drive components to rotate synchronously. That is, the drive gear 30 connected to the output of the power component 60 is the driving gear, and the other drive gears 30 are the driven gears.

[0048] Optionally, the power component 60 is a motor, and the output part of the power component 60 is the output shaft of the motor; the power component 60 is preferably a stepper motor.

[0049] Optionally, such as Figure 5 and Figure 9 As shown, a connecting shaft 31 is provided on the drive gear 30, which is the driving gear. The central axis of the connecting shaft 31 coincides with the central axis of the drive gear 30. The connecting shaft 31 is connected to the output part of the power component 60, that is, the drive gear 30 is connected to the output part of the power component 60 through the connecting shaft 31. Furthermore, the central axis of the connecting shaft 31 coincides with the central axis of the output shaft of the power component 60.

[0050] Specifically, the mounting base 10 has multiple stepped holes 15, and the first transmission members 21 of the transmission components 20 of multiple drive components are correspondingly inserted into the multiple stepped holes 15.

[0051] Optionally, the multiple air guide plates 40 have the same structure so that they can be interchanged and used interchangeably, thus ensuring the versatility of the air guide plates 40.

[0052] Optionally, the multiple drive gears 30 are exactly the same size so that they can be interchanged and used interchangeably, thus ensuring the versatility of the drive gears 30.

[0053] Optionally, all transmission gears 51 are exactly the same size to ensure the universality of transmission gears 51.

[0054] It should be noted that the air guiding mechanism of this application can control the rotation angle of the corresponding air guiding plate 40 by controlling the transmission ratio of the drive gear 30 and the transmission gear 51 meshing with it and / or the transmission ratio of two adjacent transmission gears 51 of the transmission gear set 50, thereby controlling the air guiding angle to meet the air guiding effect of different angles.

[0055] In this embodiment, the mounting base 10 is disposed above the air outlet frame 90, and the drive gear 30, the first transmission component 21, the second transmission component 22 and the third transmission component 23 of each drive component are arranged sequentially from top to bottom.

This allows for a more compact overall structure of the air guide mechanism, which helps to reduce the overall volume of the air guide mechanism.

[0057] Specifically, the mounting base 10 includes a first mounting part 12 and a second mounting part 13 that are spliced ​​together, and the first mounting part 12 and the second mounting part 13 together form a mounting cavity 11; the first mounting part 12 and the second mounting part 13 are distributed vertically.

[0058] Specifically, the main body of the power component 60 is fixedly mounted on the mounting base 10, and the main body of the power component 60 is located outside the mounting cavity 11; the output part of the power component 60 extends into the mounting cavity 11 to connect with the drive gear 30.

[0059] Specifically, the main body of the power component 60 is located above the mounting base 10, that is, the main body of the power component 60 is fixedly mounted on the first mounting part 12.

[0060] Specifically, the mounting base 10 is provided with an assembly hole 14 that communicates with the mounting cavity 11. The main body of the power component 60 is installed at the assembly hole 14, and the output part of the power component 60 extends into the mounting cavity 11 through the assembly hole 14; that is, the assembly hole 14 is provided on the first mounting part 12.

[0063] Specifically, the third transmission component 23 is installed inside the air outlet frame 90.

The air guiding mechanism of this application uses gear transmission. Compared with the linkage transmission in the prior art, on the one hand, the air guiding mechanism of this application solves the problem of time delay in the movement of the air guide plate caused by the driving method of the air guiding mechanism in the prior art, and can ensure the stability of the movement of the air guide plate.
