[0046] The structure and principle of the above-mentioned single-drive air guide plate assembly and air conditioner are introduced below through two specific embodiments.

[0047] Example 1

[0048] In the single-drive air deflector assembly of this embodiment, the first rotating arm 2 is a first crank rod assembly, and the second rotating arm 3 is a second crank rod assembly.

[0049] The direction of this embodiment is Figure 1 For reference, due to Figure 1 Close to the rear view of the single drive deflector assembly, so Figure 1 The left side is the "right" of the single drive air deflector assembly. Figure 1 The right side is the "left" of the single drive air deflector assembly. Figure 1 The upper side is the "upper" of the single drive air guide assembly. Figure 1 The lower side is the "lower" of the single drive air deflector assembly. Figure 1 The front side is the "rear" of the single drive air deflector assembly. Figure 1 The rear side is the "front" of the single-drive air deflector assembly. Based on this orientation definition, the single-drive air deflector assembly of this embodiment is described in detail below.

[0050] This embodiment provides a single-drive air guide plate assembly, see Figure 1 , comprising an air deflector 1, a first crank rod assembly and a second crank rod assembly. The air deflector 1 is rotatably arranged, the first crank rod assembly and the second crank rod assembly are respectively arranged at two opposite ends of the air deflector 1 in the rotation direction, and the first crank rod assembly and the second crank rod assembly are both rotatably connected to the air deflector 1.

[0051] Specifically, Figure 1The left-right direction is the length direction of the air guide plate 1, and the rotation of the air guide plate 1 is performed in a plane formed by the up-down direction and the front-back direction, so that the two opposite ends of the air guide plate 1 in the rotation direction are respectively the upper end of the air guide plate 1 and the lower end of the air guide plate 1. In this embodiment, the first crank rod assembly is provided at the upper end of the air guide plate 1, and the second crank rod assembly is provided at the lower end of the air guide plate 1. The first crank rod assembly and the second crank rod assembly are arranged opposite to each other in the up-down direction, and are both rotatably connected to the air guide plate 1.

[0052] Among them, the connection point of the first crank rod assembly and the air guide plate 1 is the first rotation center, and the connection point of the second crank rod assembly and the air guide plate 1 is the second rotation center. The first crank rod assembly can drive the air guide plate 1 to rotate around the second rotation center, and the second crank rod assembly can drive the air guide plate 1 to rotate around the first rotation center, and the first crank rod assembly and the second crank rod assembly rotate intermittently, that is, when the first crank rod assembly rotates, the second crank rod assembly is in a stationary state, and when the second crank rod assembly rotates, the first crank rod assembly is in a stationary state. Therefore, the single air guide plate assembly of the present invention is intermittently rotated by the first crank rod assembly and the second crank rod assembly, and the rotation centers of the two are different, which expands the rotation angle range of the air guide plate 1, so that the swing angle of the air guide plate 1 can be adjusted in a wide range to achieve wind guide of various angles of the air guide plate 1.

[0053] In order to ensure the stability of the rotation of the wind deflector 1, refer to Figure 1 The air guide plate 1 is provided with two groups of first crank rod assemblies and second crank rod assemblies, and the two groups of first crank rod assemblies and second crank rod assemblies are evenly distributed along the length direction of the air guide plate 1. The two groups of first crank rod assemblies and second crank rod assemblies can be both arranged in the middle area of ​​the length direction of the air guide plate 1, or can be respectively arranged at the two ends of the length direction of the air guide plate 1, and both are rotatably connected to the air guide plate 1. In this embodiment, the two groups of first crank rod assemblies and second crank rod assemblies are respectively arranged at the two ends of the length direction of the air guide plate 1.

[0054] See also Figure 2 A first connecting shaft 11 and a second connecting shaft 12 are respectively provided at the opposite two ends in the rotation direction of the air guide plate 1, a first connecting portion 221 is provided at one end of the first crank rod assembly close to the air guide plate 1, the first connecting portion 221 is provided with a first through hole 222 matched with the first connecting shaft 11, the first connecting shaft 11 is rotatably inserted into the first through hole 222, a second crank rod assembly is provided at one end close to the air guide plate 1 with a second connecting portion 321, the second connecting portion 321 is provided with a second through hole 322 matched with the second connecting shaft 12, the second connecting shaft 12 is rotatably inserted into the second through hole 322, thereby realizing that the first crank rod assembly and the second crank rod assembly are rotatably connected to the air guide plate 1.

[0055] Specifically, the first connecting shaft 11 is arranged at the upper end of the air guide plate 1 and extends along the length direction of the air guide plate 1. The first through hole 222 penetrates the first connecting portion 221 along the length direction of the air guide plate 1. The first crank rod assembly is rotatably mounted on the first connecting shaft 11 through the first through hole 222 to realize the rotatable connection between the first crank rod assembly and the air guide plate 1.

[0056] The second connecting shaft 12 is arranged at the lower end of the air guide plate 1 and extends along the length direction of the air guide plate 1. The second through hole 322 penetrates the second connecting portion 321 along the length direction of the air guide plate 1. The second crank rod assembly is rotatably mounted on the second connecting shaft 12 through the second through hole 322 to realize the rotatable connection between the second crank rod assembly and the air guide plate 1.

[0057] It should be noted that, although the first crank rod assembly and the second crank rod assembly are both rotatably connected to the air guide plate 1, it does not mean that the first crank rod assembly and the second crank rod assembly are always in a state of relative rotation with the air guide plate 1. The first crank rod assembly and / or the second crank rod assembly and the air guide plate 1 can be relatively stationary, relatively rotating, or synchronously rotating. For example, in the initial state, the first crank rod assembly, the second crank rod assembly, and the air guide plate 1 are all in a stationary state. When the first crank rod assembly rotates around the second rotation center, the second crank rod assembly and the air guide plate 1 rotate relatively, and the first crank rod assembly and the air guide plate 1 rotate synchronously. When the second crank rod assembly rotates around the first rotation center, the first crank rod assembly and the air guide plate 1 rotate relatively, and the second crank rod assembly and the air guide plate 1 rotate synchronously.

[0058] See also Figure 1 The intermittent rotation of the first crank rod assembly and the second crank rod assembly is realized by the driving member 4. The driving member 4 intermittently drives the first crank rod assembly and the second crank rod assembly to rotate, and drives the air guide plate 1 to rotate synchronously.

[0059] See also Figure 2 The driving member 4 includes a motor 41, a first rotating portion 211 is provided at one end of the first crank rod assembly away from the air guide plate 1, and a second rotating portion 311 is provided at one end of the second crank rod assembly away from the air guide plate 1. The motor 41 intermittently drives the first rotating portion 211 and the second rotating portion 311 to rotate, so that the first crank rod assembly and the second crank rod assembly rotate intermittently.

[0060] The motor 41 intermittently drives the first rotating part 211 and the second rotating part 311 to rotate through the output shaft 44, the first friction plate 45 and the second friction plate 46. The output shaft 44 is connected to the output end of the motor 41, the first rotating part 211 and the second rotating part 311 are rotatably sleeved on the output shaft 44, and the first friction plate 45 and the second friction plate 46 are fixedly sleeved on the output shaft 44. The first friction plate 45 is arranged to abut the first rotating part 211, and the second friction plate 46 is arranged to abut the second rotating part 311. The motor 41 intermittently drives the first friction plate 45 to pre-tighten the first rotating part 211 and the second friction plate 46 to pre-tighten the second rotating part 311, so that the first rotating part 211 and the second rotating part 311 intermittently rotate.

[0061] Its working principle is as follows: the motor 41 drives the output shaft 44 to rotate, and synchronously drives the first friction plate 45 and the second friction plate 46 to rotate. When the pre-tightening force of the first friction plate 45 on the first rotating part 211 is sufficient to drive the first rotating part 211 to rotate, the first crank rod assembly is driven to rotate through the first rotating part 211, thereby driving the wind guide plate 1 to rotate synchronously. At this time, the pre-tightening force of the second friction plate 46 and the second rotating part 311 is insufficient to drive the second rotating part 311 to rotate, and the second crank rod assembly is in a stationary state.

[0062] The motor 41 drives the output shaft 44 to rotate, and synchronously drives the first friction plate 45 and the second friction plate 46 to rotate. When the pre-tightening force of the second friction plate 46 on the second rotating part 311 is sufficient to drive the second rotating part 311 to rotate, the second crank rod assembly is driven to rotate through the second rotating part 311, thereby driving the wind guide plate 1 to rotate synchronously. At this time, the pre-tightening force of the first friction plate 45 and the first rotating part 211 is insufficient to drive the first rotating part 211 to rotate, and the first crank rod assembly is in a stationary state.

[0063] See also Figure 2 The specific structure of the middle driving member 4 is that the radial circumferential side of the output shaft 44 is provided with a first groove 441 and a second groove 442, and the first friction plate 45 is provided with a first through hole 451 matched with the first groove 441 along the axial direction of the output shaft 44, and the first friction plate 45 is fixedly connected with the output shaft 44 by the fixed connection between the first groove 441 and the first through hole 451. The second friction plate 46 is provided with a second through hole 461 matched with the second groove 442 along the axial direction of the output shaft 44, and the second friction plate 46 is fixedly connected with the output shaft 44 by the fixed connection between the second groove 442 and the second through hole 461.

[0064] Specifically, the output shaft 44 is a cylindrical structure, and the first groove 441 and the second groove 442 are both provided with a platform surface, so that the outer periphery of the first groove 441 and the second groove 442 is a structure in which an arc surface and a platform surface are connected, so that the first groove 441 and the first through hole 451 do not rotate relative to each other, and the second groove 442 and the second through hole 461 do not rotate relative to each other, so that the first friction plate 45 and the second friction plate 46 are fixedly connected to the output shaft 44.

[0065] The first friction plate 45 is arranged on a side of the first rotating portion 211 away from the second rotating portion 311, and the second friction plate 46 is arranged on a side of the second rotating portion 311 away from the first rotating portion 211. A blocking portion 4311 is convexly provided on the radial circumferential side of the output shaft 44, and the blocking portion 4311 is arranged between the first rotating portion 211 and the second rotating portion 311. The first friction plate 45, the first rotating portion 211, the blocking portion 4311, the second rotating portion 311 and the second friction plate 45 are abutted in sequence, so that the first friction plate 45, the first rotating portion 211, the second rotating portion 311 and the second friction plate 45 do not undergo relative displacement in the axial direction of the output shaft 44.

[0066] The first friction plate 45 and the second friction plate 46 of the present embodiment are both elastic parts. When the first friction plate 45 abuts against the first rotating part 211 and the second friction plate 46 abuts against the second rotating part 311, the first friction plate 45 and the second friction plate 46 are both elastically deformed so that the first friction plate 45 has a pre-tightening force on the first rotating part 211 and the second friction plate 46 has a pre-tightening force on the second rotating part 311, so that there is a possibility that the first friction plate 45 drives the first rotating part 211 to rotate synchronously, and there is a possibility that the second friction plate 46 drives the second rotating part 311 to rotate synchronously.

[0067] Whether the pre-tightening force of the first friction plate 45 on the first rotating part 211 is sufficient to drive the first rotating part 211 to rotate, and whether the pre-tightening force of the second friction plate 46 on the second rotating part 311 is sufficient to drive the second rotating part 311 to rotate is achieved through the following structure.

[0068] See also Figure 2The first crank rod assembly includes a first crank 21 and a first sliding rod 22. The first crank 21 is provided with a first rotating portion 211 at one end away from the wind deflector 1. The first crank 21 is provided with a first opening at one end close to the wind deflector 1. A first cavity is provided inside the first crank 21 along its extension direction. The first cavity is connected to the first opening. The first sliding rod 22 is provided in the first cavity and extends out of the first opening, and can slide back and forth along the extension direction of the first cavity. The first sliding rod 22 is provided with a first connecting portion 221 at one end close to the wind deflector 1. The first connecting portion 221 is provided with a first through hole 222 adapted to the first connecting shaft 11. The first connecting shaft 11 is rotatably penetrated in the first through hole 222, so that the first sliding rod 22 is rotatably connected to the wind deflector 1.

[0069] The second crank rod assembly includes a second crank 31 and a second sliding rod 32. The second crank 31 is provided with a second rotating portion 311 at one end away from the wind deflector 1. The second crank 31 is provided with a second opening at one end close to the wind deflector 1. A second cavity is provided inside the second crank 31 along its extension direction. The second cavity is connected to the second opening. The second sliding rod 32 is provided in the second cavity and extends out of the second opening, and can slide back and forth along the extension direction of the second cavity. The second sliding rod 32 is provided with a second connecting portion 321 at one end close to the wind deflector 1. The second connecting portion 321 is provided with a second through hole 322 adapted to the second connecting shaft 12. The second connecting shaft 12 is rotatably inserted into the second through hole 322, so that the second sliding rod 32 is rotatably connected to the wind deflector 1.

[0070] A first stopper is provided on the side of the first crank rod assembly away from the second crank rod assembly, and a second stopper is provided on the side of the second crank rod assembly away from the first crank rod assembly. In an initial state, the first crank rod assembly abuts against the first stopper, and the second crank rod assembly abuts against the second stopper.

[0071] It should be noted that the first retaining member can be provided at any position on the side of the first crank rod assembly away from the second crank rod assembly, and the structure of the first retaining member is not limited. The second retaining member can be provided at any position on the side of the second crank rod assembly away from the first crank rod assembly, and the structure of the second retaining member is not limited. It is only necessary to ensure that the first retaining member and the second retaining member are convenient to set and can play a retaining role.

[0072] On this basis, the working principle of the air guide plate assembly of this embodiment is:

[0073] Under the condition that the first crank rod assembly, the second crank rod assembly and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate clockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly both have a tendency to rotate clockwise. However, since the second crank rod assembly abuts against the second stopper, the abutting force is greater than the pre-tightening force of the second friction plate 46 on the second rotating part 311, so that the second friction plate 46 is not enough to drive the second rotating part 311 to rotate, so that the second crank rod assembly is in a stationary state. Since the first crank rod assembly has no abutment structure to block it, the pre-tightening force of the first friction plate 45 on the first rotating part 211 is sufficient to drive the first rotating part 211 to rotate, thereby driving the first crank rod assembly to rotate around the second rotation center through the first rotating part 211, and the first sliding rod 22 slides away from the first crank 21, and drives the air guide plate 1 to rotate synchronously until it rotates to the maximum angle.

[0074] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly both have a tendency to rotate counterclockwise. However, due to the accumulation of the pre-tightening force of the second friction plate 46 on the second rotating part 311 during the above clockwise rotation, the second rotating part 311 has a certain invisible force for clockwise rotation, therefore, the second friction plate 46 rotates in the opposite direction to offset the invisible force generated by the above clockwise rotation, until the reverse rotation is the same angle, so that the invisible force is completely offset, and in this process, the second rotating part 311 and the second crank rod assembly are stationary. Since the first crank rod assembly has no abutment structure and invisible force obstruction, the pre-tightening force of the first friction plate 45 on the first rotating part 211 is sufficient to drive the first rotating part 211 to rotate, thereby driving the first crank rod assembly to rotate in the opposite direction around the second rotation center through the first rotating part 211, and the first sliding rod 22 slides close to the first crank 21, and drives the air guide plate 1 to rotate synchronously until it returns to the initial state.

[0075] On the contrary, when the first crank rod assembly, the second crank rod assembly and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate counterclockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly both have a tendency to rotate counterclockwise. However, since the first crank rod assembly abuts against the first stopper, the abutting force is greater than the pre-tightening force of the first friction plate 45 on the first rotating part 211, so that the first friction plate 45 is not enough to drive the first rotating part 211 to rotate, so that the first crank rod assembly is in a stationary state. Since the second crank rod assembly has no abutment structure to block it, the pre-tightening force of the second friction plate 46 on the second rotating part 311 is sufficient to drive the second rotating part 311 to rotate, thereby driving the second crank rod assembly to rotate around the first rotation center through the second rotating part 311, and the second sliding rod 32 slides away from the second crank 31, and drives the air guide plate 1 to rotate synchronously until it rotates to the maximum angle.

[0076] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly both have a tendency to rotate clockwise. However, due to the accumulation of the pre-tightening force of the first friction plate 45 on the first rotating part 211 during the above counterclockwise rotation, the first rotating part 211 has a certain counterclockwise invisible force, therefore, the first friction plate 45 rotates in the opposite direction to offset the invisible force generated by the above counterclockwise rotation, until the reverse rotation is the same angle, so that the invisible force is completely offset, and in this process, the first rotating part 211 and the first crank rod assembly are stationary. Since the second crank rod assembly has no abutment structure and invisible force obstruction, the pre-tightening force of the second friction plate 46 on the second rotating part 311 is sufficient to drive the second rotating part 311 to rotate, thereby driving the second crank rod assembly to rotate in the opposite direction around the first rotation center through the second rotating part 311, and the second sliding rod 32 slides close to the second crank 31, and drives the air guide plate 1 to rotate synchronously until it returns to the initial state.

[0077] The above is the rotation principle of the single-drive air guide plate assembly of this embodiment around two rotation centers, which can expand the rotation angle range of the air guide plate 1, thereby being able to adjust the swing angle of the air guide plate 1 over a wide range to achieve air guiding of the air guide plate 1 at various angles.

[0078] In addition to the above-mentioned single-drive air guide plate assembly, this embodiment also provides an air conditioner, see Figure 3 to Figure 4The air conditioner comprises a shell 5 , on which an air outlet 51 and an air inlet 52 are provided.

[0079] In this embodiment, the air inlet 52 is arranged at the top of the housing 5, the air outlet 51 is arranged at the lower part of the front side wall of the housing 5, and the air outlet 51 is arranged obliquely. The inclined structure of the air outlet 51 is as follows: the front side wall of the housing 5 exceeds the front end of the bottom plate of the housing 5, and the air outlet 51 is arranged obliquely from the bottom end of the front side wall of the housing 5 to the front end of the bottom plate of the housing 6.

[0080] The aforementioned air guide plate assembly is arranged at the air outlet 51 of the shell 5, specifically, the air guide plate 1 is arranged at the air outlet 51 at an angle to close the air outlet 51, and the air guide plate 1 can rotate at the air outlet 51. The first crank rod assembly and the second crank rod assembly are arranged on the shell 5, specifically, the driving member 4, the first crank rod assembly and the second crank rod assembly are all arranged in the shell 5, and the first crank rod assembly and the second crank rod assembly pass through the shell 5 and are rotatably connected to the air guide plate 1. In this embodiment, the first stopper is the shell 5 of the first crank rod assembly located above the air outlet 51, and the second stopper is the shell 5 of the second crank rod assembly located below the air outlet 51.

[0081] On this basis, the air conditioner of this embodiment can achieve the following air outlet modes:

[0082] The first crank rod assembly, the second crank rod assembly and the air guide plate 1 are in an initial state, and the air conditioner is in a closed state.

[0083] Under the condition that the first crank rod assembly, the second crank rod assembly and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate clockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a tendency to rotate clockwise. At this time, because the lower part of the second crank rod assembly abuts the housing 6, the abutting force is greater than the pre-tightening force of the second friction plate 46 on the second rotating part 311, so that the second friction plate 46 is insufficient to drive the second rotating part 311 to rotate, so that the second crank rod assembly is in a stationary state. Since the first crank rod assembly has no abutment structure to block it, the pre-tightening force of the first friction plate 45 on the first rotating part 211 is sufficient to drive the first rotating part 211 to rotate, thereby driving the first crank rod assembly to rotate around the second rotation center through the first rotating part 211, and the first sliding rod 22 slides away from the first crank 21, and drives the air guide plate 1 to rotate clockwise by a certain angle synchronously. When the air guide plate 1 and the bottom plate of the housing 6 are at an acute angle, the air conditioner blows air upward. When the air guide plate 1 rotates to be parallel to the bottom plate of the housing 6, the air conditioner blows air horizontally.

[0084] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly both have a tendency to rotate counterclockwise. However, due to the accumulation of the pre-tightening force of the second friction plate 46 on the second rotating part 311 during the above clockwise rotation, the second rotating part 311 has a certain invisible force for clockwise rotation, therefore, the second friction plate 46 rotates in the opposite direction to offset the invisible force generated by the above clockwise rotation, until the reverse rotation is the same angle, so that the invisible force is completely offset, and in this process, the second rotating part 311 and the second crank rod assembly are stationary. Since the first crank rod assembly has no abutment structure and invisible force obstruction, the pre-tightening force of the first friction plate 45 on the first rotating part 211 is sufficient to drive the first rotating part 211 to rotate, thereby driving the first crank rod assembly to rotate in the opposite direction around the second rotation center through the first rotating part 211, and the first sliding rod 22 slides close to the first crank 21, and drives the air guide plate 1 to rotate synchronously until it returns to the initial state to turn off the air conditioner.

[0085] On the contrary, when the first crank rod assembly, the second crank rod assembly and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate counterclockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a tendency to rotate counterclockwise. However, since the first crank rod assembly abuts against the upper housing 6, the abutting force is greater than the pre-tightening force of the first friction plate 45 on the first rotating part 211, so that the first friction plate 45 is not enough to drive the first rotating part 211 to rotate, so that the first crank rod assembly is in a stationary state. Since the second crank rod assembly has no abutment structure to block it, the pre-tightening force of the second friction plate 46 on the second rotating part 311 is sufficient to drive the second rotating part 311 to rotate, thereby driving the second crank rod assembly to rotate around the first rotation center through the second rotating part 311, and the second sliding rod 32 slides away from the second crank 31, and drives the air guide plate 1 to rotate a certain angle counterclockwise synchronously. When the air guide plate 1 and the front side wall of the shell 6 have an acute angle, the air conditioner blows air downward, and when the air guide plate 1 rotates to be parallel to the front side wall of the shell 6, the air conditioner blows air vertically.

[0086] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly both have a tendency to rotate clockwise. However, due to the accumulation of the pre-tightening force of the first friction plate 45 on the first rotating part 211 during the above counterclockwise rotation, the first rotating part 211 has a certain counterclockwise invisible force, therefore, the first friction plate 45 rotates in the opposite direction to offset the invisible force generated by the above counterclockwise rotation, until the reverse rotation is the same angle, so that the invisible force is completely offset, and in this process, the first rotating part 211 and the first crank rod assembly are stationary. Since the second crank rod assembly has no abutment structure and invisible force obstruction, the pre-tightening force of the second friction plate 46 on the second rotating part 311 is sufficient to drive the second rotating part 311 to rotate, thereby driving the second crank rod assembly to rotate in the opposite direction around the first rotation center through the second rotating part 311, and the second sliding rod 32 slides close to the second crank 31, and drives the air guide plate 1 to rotate synchronously until it returns to the initial state to turn off the air conditioner.

[0087] Therefore, the air conditioner of this embodiment rotates with two rotation centers through the air guide plate 1, and the rotation angle range of the air guide plate 1 relative to the shell 5 becomes larger, so that the swing angle of the air guide plate 1 relative to the shell 5 can be adjusted in a wide range, thereby realizing horizontal air outlet, vertical air outlet and angle air outlet, so that the air outlet direction of the air conditioner is diverse to meet user needs.

[0088] Example 2

[0089] In the single-drive air guide plate assembly of this embodiment, the first rotating arm 2 is a first crank assembly, and the second rotating arm 3 is a second crank assembly.

[0090] The direction of this embodiment is Figure 5 For reference, due to Figure 5 Close to the rear view of the single drive deflector drive, so Figure 5 The left side is the "right" of the single drive air guide plate drive. Figure 5 The right side is the "left" of the single drive air guide plate drive. Figure 5 The upper side of is the "upper" of the single drive air guide plate drive. Figure 5 The lower side is the "lower" of the single drive air guide plate drive. Figure 5 The front side is the "rear" of the single drive air deflector drive. Figure 5 The rear side is the "front" of the single-drive air guide plate driving member. Based on this orientation definition, the single-drive air guide plate driving member of this embodiment is described in detail below.

[0091] This embodiment provides a wind deflector driving member, see Figure 5 , comprising an air guide plate 1, a first crank assembly and a second crank assembly. The air guide plate 1 is rotatably arranged, the first crank assembly and the second crank assembly are respectively arranged at two opposite ends of the air guide plate 1 in the rotation direction, and the first crank assembly and the second crank assembly are both rotatably connected to the air guide plate 1.

[0092] Specifically, Figure 5 The left-right direction is the length direction of the air guide plate 1, and the rotation of the air guide plate 1 is performed in a plane formed by the up-down direction and the front-back direction, so that the two opposite ends of the air guide plate 1 in the rotation direction are the upper end of the air guide plate 1 and the lower end of the air guide plate 1. In this embodiment, the first crank assembly is arranged at the lower end of the air guide plate 1, and the second crank assembly is arranged at the upper end of the air guide plate 1. The first crank assembly and the second crank assembly are arranged opposite to each other in the up-down direction, and are both rotatably connected to the air guide plate 1.

[0093] In this embodiment, the first crank assembly and the second crank assembly rotate synchronously, and the second crank assembly is a retractable structure along its extension direction. Therefore, the air deflector 1 can rotate at two rotation centers, expanding the rotation angle range of the air deflector 1, so that the swing angle of the air deflector 1 can be adjusted in a wide range, so as to realize air deflection of the air deflector 1 at various angles.

[0094] The working principle of the air guide plate driving member of this embodiment is as follows:

[0095] When the first crank assembly and the second crank assembly rotate synchronously to extend the second crank assembly, the rotation center is close to the connection between the first crank assembly and the air guide plate 1. When the first crank assembly and the second crank assembly rotate synchronously to shrink the second crank assembly, the rotation center is close to the connection between the second crank assembly and the air guide plate 1, thereby changing the rotation center of the air guide plate 1 and expanding the swing angle range of the air guide plate 1.

[0096] In order to ensure the stability of the rotation of the wind deflector 1, refer to Figure 1 The air guide plate 1 is provided with two groups of first crank rod assemblies and second crank rod assemblies, and the two groups of first crank rod assemblies and second crank rod assemblies are evenly distributed along the length direction of the air guide plate 1. The two groups of first crank rod assemblies and second crank rod assemblies can be both arranged in the middle area of ​​the length direction of the air guide plate 1, or can be respectively arranged at the two ends of the length direction of the air guide plate 1, and both are rotatably connected to the air guide plate 1. In this embodiment, the two groups of first crank rod assemblies and second crank rod assemblies are respectively arranged at the two ends of the length direction of the air guide plate 1.

[0097] The synchronous rotation of the first crank rod assembly and the second crank rod assembly is achieved by driving the driving member 4 .

[0098] 6 , the driving member 4 includes a motor 41, and a first gear 42 is provided at one end of the first crank assembly away from the air guide plate 1, and the first gear 42 is connected to the output end of the motor 41, so that the first gear 42 is driven to rotate by the motor 41. A second gear 43 is provided at one end of the second crank assembly away from the air guide plate 1, and the second gear 43 rotates synchronously with the first gear 42, so that the first crank rod assembly and the second crank rod assembly are driven to rotate synchronously by the motor 41.

[0099] Specifically, an idler gear 47 is provided between the first gear 42 and the second gear 43, and the first gear 42, the idler gear 47 and the second gear 43 are meshed in sequence, and an odd number of idler gears 47 are provided. Thus, the rotation of the second gear 43 is achieved by the transmission of the first gear 42 through the idler gear 47, and the odd number of idler gears 47 is provided to ensure the synchronous rotation between the first gear 42 and the second gear 43.

[0100] In this embodiment, the first gear 42, the idler gear 47 and the second gear 43 are all mounted on the mounting plate 43. The mounting plate 43 is arranged on the output side of the motor 41, and the output end of the motor 41 is rotatably connected to the first gear 42 through the mounting plate 43, and the first gear 42, the idler gear 47 and the second gear 43 are all rotatably mounted on the mounting plate 43. Thus, the first gear 42, the idler gear 47 and the second gear 43 are effectively mounted without affecting the rotation of the first gear 42, the idler gear 47 and the second gear 43.

[0101] For the specific structures of the first crank assembly and the second crank assembly of this embodiment, refer to Figure 6 The first crank assembly includes a first crank 21, one end of the first crank 21 close to the air deflector 1 is rotatably connected to the air deflector 1, and one end of the first crank 21 away from the air deflector 1 is provided with a first gear 42, and the first crank 21 is fixedly connected to the first gear 42. Therefore, the first gear 42 can drive the first crank 21 to rotate, so that the first crank 21 rotates relative to the air deflector 1.

[0102] The second crank assembly includes a second crank 31 and a sliding rod 33. The second crank 31 is a structure that penetrates along its extension direction. The sliding rod 33 is arranged in the second crank 31 and can slide back and forth along the extension direction of the second crank 31. A second gear 43 is fixedly arranged at one end of the second crank 31 away from the air deflector 1. An end of the sliding rod 33 close to the air deflector 1 is rotatably connected to the air deflector 1. Thus, the second gear 43 can drive the second crank 31 and the sliding rod 33 to rotate, so that the sliding rod 33 rotates relative to the air deflector 1.

[0103] Furthermore, since the sliding rod 33 can slide in the second crank 31 , the rotation center of the air guide plate 1 can be changed by changing the synchronous rotation direction of the first gear 42 and the second gear 43 , thereby increasing the swing angle range of the air guide plate 1 .

[0104] The sliding connection between the sliding rod 33 and the first crank 21 and the air guide plate 1 is achieved through the following structure.

[0105] A second slot is formed at one end of the air guide plate 1 corresponding to the sliding rod 33, and a second connecting portion 321 is formed at one end of the sliding rod 33 close to the air guide plate 1, and the second connecting portion 321 is rotatably mounted in the second slot. A first slot is formed at one end of the air guide plate 1 corresponding to the first crank 21, and a first connecting portion 221 is formed at one end of the first crank 21 close to the air guide plate 1, and the first connecting portion 221 is rotatably mounted in the first slot.

[0106] In this embodiment, the second card slot is disposed at the upper end of the air guide plate 1 , the first card slot is disposed at the lower end of the air guide plate 1 , and both the first card slot and the second card slot extend along the length direction of the air guide plate 1 .

[0107] Further, in order to prevent the first connection part 221 from being disengaged from the first slot and the second connection part 321 from being disengaged from the second slot, a second clamping protrusion is provided on the outer edge of the second slot, and the second clamping protrusion is provided on both sides of the second connection part 321 perpendicular to its rotation direction, that is, the second clamping protrusion is provided on the left and right sides of the second connection part 321, the second clamping protrusion is provided in contact with the second connection part 321, and the second connection part 321 can rotate relative to the second clamping protrusion. A first clamping protrusion is provided on the outer edge of the first slot, and the first clamping protrusion is provided on both sides of the first connection part 221 perpendicular to its rotation direction, that is, the first clamping protrusion is provided on the left and right sides of the first connection part 221, the first clamping protrusion is provided in contact with the first connection part 221, and the first connection part 221 can rotate relative to the first clamping protrusion. Thus, the first clamping protrusion can limit the first connection part 221 without affecting the rotation of the first connection part 221 in the first slot, and the second clamping protrusion can limit the second connection part 321 without affecting the rotation of the second connection part 321 in the second slot.

[0108] In addition to the above-mentioned air guide plate driving member, this embodiment also provides an air conditioner, referring to Figure 7 and Figure 8 The air conditioner comprises a shell 5 , on which an air outlet 51 and an air inlet 52 are provided.

[0109] In this embodiment, the air inlet 52 is arranged at the top of the housing 5, the air outlet 51 is arranged at the lower part of the front side wall of the housing 5, and the air outlet 51 is arranged obliquely. The inclined structure of the air outlet 51 is as follows: the front side wall of the housing 5 exceeds the front end of the bottom plate of the housing 5, and the air outlet 51 is arranged obliquely from the bottom end of the front side wall of the housing 5 to the front end of the bottom plate of the housing 5.

[0110] The aforementioned air guide plate assembly is disposed at the air outlet 51 of the housing 5. Specifically, the air guide plate 1 is disposed at the air outlet 51 at an angle to close the air outlet 51, and the air guide plate 1 can rotate at the air outlet 51. The driving member 4, the first crank assembly and the second crank assembly are disposed on the housing 5.

[0111] The air outlet mode of the air conditioner in this embodiment is as follows:

[0112] The air guide plate 1 closes the air outlet 51, and the air conditioner is in the off state.

[0113] The motor 41 drives the first gear 42 and the second gear 43 to rotate clockwise, thereby driving the first crank 21, the second crank 31 and the sliding rod 33 to rotate clockwise, and the sliding rod 33 slides toward the air guide plate 1 to push the air guide plate 1 to rotate clockwise until the air guide plate 1 rotates perpendicular to the front side wall of the housing 5, so that the air conditioner can discharge air horizontally. In the process of rotation, the air conditioner can discharge air at an angle. When the air conditioner needs to be turned off, the reverse operation can be performed.

[0114] The motor 41 drives the first gear 42 and the second gear 43 to rotate counterclockwise, thereby driving the first crank 21, the second crank 31 and the sliding rod 33 to rotate counterclockwise, and the sliding rod 33 slides away from the air guide plate 1 to pull the air guide plate 1 to rotate counterclockwise until the air guide plate 1 rotates to be parallel to the front side wall of the housing 5, so that the air conditioner can discharge air vertically. In the process of rotation, the air conditioner discharges air at an angle. When the air conditioner needs to be turned off, the reverse operation can be performed.

[0115] When the air guide plate 1 rotates to vertically discharge air, the upper portion of the air guide plate 1 overlaps with the lower portion of the front side wall of the housing 5, and at this time, the second crank assembly needs to pass through the front side wall of the housing 5 to connect with the upper end portion of the air guide plate 1. Therefore, the housing 5 is provided with a slide groove 53 corresponding to the second crank assembly, and the slide groove 53 is adapted to the second crank assembly so that the second crank assembly can rotate in the slide groove 53.

[0116] Specifically, the radial dimensions of the slide groove 53 and the sliding rod 33 are matched, so that the sliding rod 33 can pass through the slide groove 53 and rotate in the slide groove 53 without affecting the rotation effect of the air guide plate 1 .

[0117] Therefore, the air conditioner of this embodiment rotates with two rotation centers through the air guide plate 1, and the rotation angle range of the air guide plate 1 relative to the shell 5 becomes larger, so that the swing angle of the air guide plate 1 relative to the shell 5 can be adjusted in a wide range, thereby realizing horizontal air outlet, vertical air outlet and angle air outlet, so that the air outlet direction of the air conditioner is diverse to meet user needs.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
