[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0020] Existing air guide plate drive mechanisms include a first link and a second link. The first link is rotatably connected to the air guide plate via a first rotating shaft, and the second link is rotatably connected to the air guide plate via a second rotating shaft. The air guide plate rotates by utilizing the speed difference between the first and second links. However, in existing designs where both links are connected to the air guide plate via rotating shafts, the distance between the first and second rotating shafts is fixed. Therefore, the speed difference between the first and second links must ensure that the distance between the first and second rotating shafts remains constant; otherwise, the air guide plate is prone to jamming, or the rotating shafts are prone to wear. Furthermore, due to process errors, mold deformation, and other factors, the distance between the first and second rotating shafts cannot remain constant in actual production. Therefore, existing drive schemes where both links are rotatably connected to the air guide plate are prone to causing jamming during rotation.

[0021] This disclosure provides a driving mechanism for an air guide plate, such as... Figures 1 to 25 As shown.

[0022] The drive mechanism can also be called a drive device or drive structure.

[0023] The drive mechanism includes a first link 3, which moves under the drive of the drive assembly. The first link 3 includes a first guide plate connection end 31 for connecting with the rotating connector 2 of the air guide plate 1.

[0024] The drive mechanism also includes a second link 4, which moves under the drive of the drive assembly. The second link 4 includes a second guide plate connection end 41 for connecting with the rotating connector 2 of the air guide plate 1.

[0025] The first guide plate connecting end 31 of the first connecting rod 3 is driven to connect with the rotating connecting piece 2.

[0026] The second guide plate connecting end 41 of the second connecting rod 4 is rotatably connected to the rotating connecting piece 2.

[0027] The first link 3 and the second link 4 drive the air guide plate 1 to extend and rotate.

[0028] In the driving mechanism for the air guide plate provided in this embodiment, the first connecting rod 3 is driven to the rotating connecting member 2 of the air guide plate 1 to drive the air guide plate 1 to rotate, thereby improving the smoothness of the air guide plate 1 during rotation and avoiding the problem of jamming of the air guide plate 1; the second connecting rod 4 is rotatably connected to the rotating connecting member 2 of the air guide plate 1 to drive the air guide plate 1 to extend.

[0029] In this way, there is no fixed distance between the two shafts of the two connecting rods mentioned above. Instead, the speed difference between the first connecting rod 3 and the second connecting rod 4 is directly reflected in the rotation angle of the air guide plate 1. Even if the actual production drive mechanism deviates from the design scheme, the air guide plate 1 will not get stuck during rotation, and the second guide plate connection end 41 of the second connecting rod 4 will not be worn.

[0030] As can be seen, the driving mechanism provided in this embodiment improves the stability of the driving process of the air guide plate 1. Furthermore, the driving mechanism provided in this embodiment eliminates the fixed distance between the two rotating shafts, thus allowing the first link 3 and the second link 4 to rotate the air guide plate 1 without needing to extend a large distance, reducing the size of the driving mechanism and the space it occupies in the indoor unit of the air conditioner.

[0031] The first guide plate connecting end 31 of the first connecting rod 3 is driven to be connected to the rotating connecting member 2. This can be understood as meaning that there is no need for an active driving force such as a motor between the first guide plate connecting end 31 of the first connecting rod 3 and the rotating connecting member 2; instead, the driving connection is achieved through the meshing of teeth. Figure 9 and Figure 10 As shown.

[0032] The rotating connector 2 provides a connection position for the connection between the first link 3 and the second link 4 and the air guide plate 1. Optionally, the rotating connector 2 of the air guide plate 1 can be part of the air guide plate body or a separate component disposed on the air guide plate body. Optionally, the rotating connector 2 is integrally formed with the air guide plate body; or, the rotating connector 2 is snapped into the air guide plate body, etc.

[0033] Optionally, the rotating connector 2 is perpendicular to the air guide plate body. For example... Figure 18 and Figure 19 As shown.

[0034] Optionally, the rotating connector 2 includes a second toothed portion 21 and a rotating connecting portion 23. The second toothed portion 21 is used for a driving connection with the first guide plate connecting end 31 of the first connecting rod 3; the rotating connecting portion 23 is used for a rotatable connection with the second guide plate connecting end 41 of the second connecting rod 4. The rotating connecting portion 23 has a pivot center O1, the second toothed portion 21 has a gear center O2, and the pivot center and the gear center overlap. Figure 6 , Figure 7 and Figure 8 As shown.

[0035] The rotating connection part 23 has a pivot center O1, and the second tooth part 21 of the rotating connection 2 has a gear center O2. The pivot center O1 and the gear center O2 overlap. In this way, the gear center O2 that drives the first connecting rod 3 to rotate the air guide plate 1 overlaps with the pivot center O1 that connects the first connecting rod 3 to the air guide plate 1, thus eliminating the fixed distance between the two rotating shafts mentioned above and avoiding the jamming problem that occurs when the air guide plate 1 rotates.

[0036] Optionally, during the extension and rotation of the air guide plate 1, the first guide plate connecting end 31 of the first connecting rod 3, the second guide plate connecting end 41 of the second connecting rod 4, and the rotating connecting piece 2 of the air guide plate 1 all move along the first preset trajectory line L, such as... Figure 2 As shown.

[0037] The first link 3 and the second link 4 extend under the driving action of the drive assembly. The extension or retraction trajectory of the rotating connector 2 of the air guide plate 1 can be the extension or retraction trajectory of the pivot center O1 of the rotating connection part 23. In this embodiment, the first guide plate connecting end 31, the second guide plate connecting end 41, and the rotating connector 2 all move along the first preset trajectory line L. Optionally, the extension or retraction trajectory of the second guide plate connecting end 41 overlaps with that of the rotating connector 2.

[0038] Optionally, the first preset trajectory line L is a straight line. Optionally, the first guide plate connecting end 31 of the first connecting rod 3 is provided with a first tooth, wherein the first tooth meshes with the second tooth 21 to drive the air guide plate 1 to rotate. Figure 9 and Figure 10 As shown, the air guide plate body is fixedly connected to the rotating connector 2, and the second tooth 21 is fixedly disposed on the rotating connector 2. Thus, the rotation of the second tooth 21 is reflected in the rotation of the air guide plate body. When the movement speed of the first tooth of the first connecting rod 3 is different from the movement speed of the second tooth 21, the first tooth meshes with the second tooth 21, causing the second tooth 21 to rotate, thereby driving the air guide plate 1 to rotate. Optionally, the second tooth 21 is gear-shaped.

[0039] Optionally, the first tooth portion is a strip-shaped tooth portion. Optionally, the first tooth portion is a straight line.

[0040] Optionally, the drive assembly includes a drive motor and a crank 5, wherein the crank 5 is drivenly connected to the first connecting rod 3 and the second connecting rod 4 to drive the first connecting rod 3 and the second connecting rod 4 to move. Figures 11 to 15 As shown. Crank 5 is mounted on the motor shaft of the drive motor, thereby enabling the drive motor to rotate crank 5. Crank 5 is driven to extend the first connecting rod 3; and crank 5 is driven to extend or retract the second connecting rod 4.

[0041] Optionally, the first connecting rod 3 includes a first drive groove 32, the second connecting rod 4 includes a second drive groove 42, and the crank 5 includes a first protrusion 51 and a second protrusion 52, wherein the first protrusion 51 slides along the first drive groove 32, and the second protrusion 52 slides along the second drive groove 42. Figures 4 to 6 As shown. The first protrusion 51 of the crank 5 slides along the first drive groove 32, thereby driving the first connecting rod 3 to extend; the second protrusion 52 of the crank 5 slides along the second drive groove 42, thereby driving the second connecting rod 4 to extend or retract.

[0042] Optionally, the first connecting rod 3 further includes a third drive groove 33, and the crank 5 further includes a third protrusion 53, wherein the third protrusion 53 slides along the third drive groove 33. In this way, the first connecting rod 3 moves under the driving action of the first protrusion 51 and the second protrusion 52.

[0043] Optionally, the first guide plate connecting end 31 of the first link 3 is driven to connect with the rotating connector 2 to drive the air guide plate 1 to rotate. Under the driving action of the first guide plate connecting end 31 of the first link 3, the air guide plate 1 rotates.

[0044] Optionally, the first guide plate connecting end 31 of the first connecting rod 3 is provided with a first tooth, and the rotating connector 2 is provided with a second tooth 21. The first tooth and the second tooth 21 mesh with each other to drive the air guide plate 1 to rotate. The meshing of the first tooth and the second tooth 21 causes the second tooth 21 of the rotating connector 2 to rotate under the driving force of the first tooth, thereby causing the air guide plate 1 to rotate.

[0045] Optionally, the first tooth is a strip-shaped tooth, and the second tooth 21 is a gear. The strip-shaped first tooth meshes with the gear-shaped second tooth 21. When the extension speed of the strip-shaped first tooth is different from the extension speed of the second tooth 21, the meshing position of the first tooth and the second tooth 21 changes, thereby causing the second tooth 21 to rotate.

[0046] Optionally, when the air guide plate 1 is in the closed state, the first tooth includes an initial engagement section 311 that meshes with the second tooth 21, and a first tooth section 312 and a second tooth section 313 located at both ends of the initial engagement section 311, and the first tooth section 312 is disposed close to the air guide plate 1. Figure 10 As shown. When the air guide plate 1 rotates from the closed state to the upward opening state, the initial engagement section 311 and the first tooth section 312 of the first tooth successively engage with the second tooth section 21, as shown. Figures 28 to 31 As shown; when the air guide plate 1 rotates from the upward opening state to the downward opening state, the first tooth segment 312, the initial engagement segment 311, and the second tooth segment 313 of the first tooth part sequentially engage with the second tooth part 21, as shown. Figures 32 to 34 As shown.

[0047] The first tooth section is divided into an initial engagement segment 311, a first tooth segment 312, and a second tooth segment 313. The initial engagement segment 311 is defined as the portion of the first tooth section that engages with the second tooth section 21 when the air guide plate 1 is in the closed state. The first tooth segment 312 and the second tooth segment 313 are located at opposite ends of the initial engagement segment 311, with the first tooth segment 312 being closer to the air guide plate 1.

[0048] When the air guide plate 1 rotates from the closed state to the upward-opening state, the initial engagement section 311 and the first toothed section 312 sequentially engage with the second toothed section 21. Optionally, when the air guide plate 1 rotates to the maximum upward-opening angle, the end of the first toothed section 312 engages with the second toothed section 21. Figure 31 As shown.

[0049] When the air guide plate 1 rotates from the upward opening state to the downward opening state, starting from the end of the first tooth segment 312, the first tooth segment 312, the initial meshing segment 311, and the second tooth segment 313 sequentially mesh with the second tooth 21.

[0050] Optionally, when the air guide plate 1 rotates from the upward opening state to the downward opening state, and the initial meshing section 311 of the first tooth meshes with the second tooth 21, the air guide plate 1 is in a wraparound air supply state. For example... Figure 32 As shown. It can be understood that when the air guide plate 1 is in the wraparound air supply mode, the air guide plate 1 is in the upward and downward air supply mode at the same time.

[0051] When the speed of the second link 4 is different from that of the first link 3, the first tooth and the second tooth 21 mesh to drive the air guide plate 1 to rotate.

[0052] Under the driving force of crank 5, the first connecting rod 3 extends; the air guide plate 1 also extends or retracts under the driving force of the second connecting rod 4. When the extension speed of the second connecting rod 4 is different from that of the first connecting rod 3, or when the second connecting rod 4 retracts and the first connecting rod 3 extends, the first tooth and the second tooth 21 mesh, and the air guide plate 1 rotates.

[0053] Optionally, the extension direction of the connecting rod is defined as the positive direction. When the extension speed of the second connecting rod 4 is greater than the extension speed of the first connecting rod 3, the air guide plate 1 opens upward.

[0054] When the air guide plate 1 moves from the closed state to the upward opening state, the first connecting rod 3 extends under the drive of the crank 5, and the second connecting rod 4 also extends under the drive of the crank 5. The air guide plate 1 extends under the drive of the second connecting rod 4. Optionally, the extension speed of the air guide plate 1 is the same as the extension speed of the second connecting rod 4. When the extension speed of the second connecting rod 4 is greater than the extension speed of the first connecting rod 3, the engagement position of the first tooth that meshes with the second tooth 21 gradually moves downward, for example, from the initial engagement section 311 to the first tooth section 312. At this time, the air guide plate 1 gradually opens upward.

[0055] Optionally, the extension direction of the connecting rod is defined as the positive direction. When the movement speed of the second connecting rod 4 is less than the movement speed of the first connecting rod 3, the air guide plate 1 opens downward.

[0056] When the air guide plate 1 moves from the upward opening state to the downward opening state, the first connecting rod 3 extends under the drive of the crank 5. The second connecting rod 4, also driven by the crank 5, extends for a period of time and retracts for a period of time. It can be understood that when the second connecting rod 4 retracts, its direction of movement is opposite to the positive direction, and its speed is negative. Therefore, when the second connecting rod 4 retracts and the first connecting rod extends, the speed of the first connecting rod 3 is greater than the speed of the second connecting rod 4. When the second connecting rod 4 extends, the speed of the first connecting rod 3 is also greater than the speed of the second connecting rod 4. Therefore, when the air guide plate 1 changes from the upward opening state to the downward opening state, the speed of the second connecting rod 4 is less than the speed of the first connecting rod 3, thus pushing the air guide plate downwards.

[0057] When the speed of the second link 4 is less than the speed of the first link 3, the engagement position of the first tooth that meshes with the second tooth 21 gradually moves upward. For example, the first tooth segment 312, the initial engagement segment 311, and the second tooth segment 313 sequentially mesh with the second tooth 21. At this time, the air guide plate 1 opens downward. Optionally, the first link 3 extends at this time.

[0058] Optionally, the second guide plate connecting end 41 of the second connecting rod 4 is rotatably connected to the rotating connector 2 to drive the air guide plate 1 to extend or retract. Optionally, the rotating connector 2 is provided with a rotating shaft, which is engaged with the second guide plate connecting end 41 of the second connecting rod 4 to realize the rotatable or pivotal connection between the second connecting rod 4 and the air guide plate 1. For example, the air guide plate 1 can rotate relative to the second connecting rod 4.

[0059] Optionally, the rotating connector 2 includes a connecting seat 22, a second tooth 21, and a rotating connecting part 23. The second tooth 21 is used for a driving connection with the first connecting rod 3, and the rotating connecting part 23 is used for a rotatable connection with the second connecting rod 4. The rotating connector 2 is provided with the second tooth 21, which can be driven to the first connecting rod 3. For example, the second tooth 21 is a gear, and the first tooth is a rack; the gear and rack are driven to each other. The rotating connector 2 is also provided with the rotating connecting part 23, which can be rotatably connected to the second connecting rod 4, causing the air guide plate 1 and the second connecting rod 4 to rotate relative to each other.

[0060] Optionally, the second tooth portion 21 includes a first tooth end connecting surface 211 and a second tooth end connecting surface 212, wherein the first tooth end connecting surface 211 of the second tooth portion 21 is connected to the connecting seat 22, and the rotatable connecting portion 23 is connected to the second tooth end connecting surface 212 of the second tooth portion 21. Figure 7 As shown.

[0061] Optionally, the first tooth end connecting surface 211 and the second tooth end connecting surface 212 are disposed opposite to each other. Optionally, the connecting seat 22 and the second tooth 21 are integrally formed; or, the second tooth 21 and the rotating connecting part 23 are integrally formed; or, the connecting seat 22, the second tooth 21 and the rotating connecting part 23 are integrally formed.

[0062] Optionally, the second guide plate connecting end 41 of the second connecting rod 4 is provided with a sleeve through groove 411, wherein the rotating connecting part 23 is engaged with the edge of the sleeve through groove 411. The rotating connecting part 23 can be a rotating shaft, which includes a rotating shaft engaging end away from the second tooth 21. The rotating shaft engaging end is provided with an engaging protrusion. The rotating shaft passes through the sleeve through groove 411, and the engaging protrusion abuts against the edge of the sleeve through groove 411. The rotating shaft can rotate within the sleeve through groove 411. Figure 5 As shown.

[0063] Optionally, the first guide plate connecting end 31 of the first connecting rod 3 is provided with a first tooth, which meshes with the second tooth 21 of the rotating connector 2. The second guide plate connecting end 41 also includes a receiving end 412, which is disposed on the side of the sleeve through groove 411 near the air guide plate 1. The receiving end 412 has a rack receiving groove 48 inside, which is used to receive the first tooth during the extension process. Figure 25 As shown.

[0064] The rack receiving groove 48 is provided along the extension direction of the first tooth and is used to accommodate the first tooth during the extension process. For example, when the air guide plate 1 rotates from the circumferential air supply state to the downward opening state, the second tooth segment 313 of the first tooth engages with the second tooth segment 21. At this time, the first tooth segment 312 of the first tooth is located in the rack receiving groove 48; or, the first tooth segment 312 and the initial engagement segment 311 of the first tooth are both located in the rack receiving groove 48. Figure 33 As shown.

[0065] Optionally, the rotating connector 2 is disposed at the first mounting position of the air guide plate 1, wherein the first mounting position is provided with a clearance groove 11, which is used to avoid the receiving end 412 of the second connecting rod 4 when the air guide plate 1 and the second connecting rod 4 rotate relative to each other. Figure 18 As shown. The clearance groove 11 can be a groove that is recessed inward from the inner surface of the air guide plate 1. The receiving end 412 is the part of the second connecting rod 4 closest to the air guide plate 1. The setting of the clearance groove 11 provides clearance space for the relative rotation of the air guide plate 1 and the second connecting rod 4, avoiding the problem of jamming or wear of the air guide plate 1 during rotation.

[0066] Optionally, when the speed at which the drive assembly drives the first link 3 is less than the speed at which the second link 4 moves, the air guide plate 1 is in the first air guiding direction; when the speed at which the drive assembly drives the first link 3 is greater than the speed at which the second link 4 moves, the air guide plate 1 is in the second air guiding direction.

[0067] Optionally, the first airflow direction is upward and the second airflow direction is downward.

[0068] Optionally, the first guide plate connecting end 31 of the first connecting rod 3 is provided with a first tooth, and the rotating connecting member 2 of the air guide plate 1 is provided with a second tooth 21. The first tooth and the second tooth 21 are meshed together. When the movement speed of the first connecting rod 3 is different from the movement speed of the air guide plate 1, the first tooth and the second tooth 21 mesh together, the second tooth 21 rotates, and thus drives the air guide plate 1 to rotate.

[0069] Optionally, the first drive slot 32 includes a first initial slot segment 321, and the second drive slot 42 includes a second initial slot segment 421, wherein when the air guide plate 1 is in the closed air outlet position, the distance between the first initial slot segment 321 and the air guide plate 1 is less than the distance between the second initial slot segment 421 and the air guide plate 1. Figure 28 As shown.

[0070] When the air guide plate 1 is in the closed state, the vertical distance T1 between the first initial groove segment 321 and the inner surface of the air guide plate 1 is the distance between the first initial groove segment 321 and the air guide plate 1, and the vertical distance T2 between the second initial groove segment 421 and the inner surface of the air guide plate 1 is the distance between the second initial groove segment 421 and the air guide plate 1, and T1 < T2. Optionally, the first driving end 3211 of the first initial groove segment 321 is flared.

[0071] Optionally, the second drive groove 42 is provided with a protruding section 422, wherein when the second protrusion 52 slides to the protruding section 422 of the second drive groove 42, the air guide plate 1 has the maximum air delivery angle along the first air guiding direction. Figure 31 As shown. For example, when the second protrusion 52 slides to the protrusion section 422, the air guide plate 1 has the maximum air delivery angle in the upward opening state.

[0072] Optionally, the second drive groove 42 is further provided with a second end groove section 423, the second initial groove section 421 is disposed at one end of the protruding section 422, and the second end groove section 423 is disposed at the second end of the protruding section 422. When the second protruding post 52 slides along the second initial groove section 421, the air guide plate 1 has a first air guiding direction, such as... Figure 30 As shown, it opens upwards; when the second protrusion 52 slides along the second end groove 423, the air guide plate 1 has a second air guiding direction, such as... Figure 33 It opens downwards as shown.

[0073] Optionally, the protruding section 422 protrudes from the second initial groove section 421 and the second end groove section 423.

[0074] When the second protrusion 52 slides along the second initial groove 421, the air guide plate 1 has an upward air guiding direction; when the second protrusion 52 slides along the second end groove 423, the air guide plate 1 has a downward air guiding direction.

[0075] Optionally, the first connecting rod 3 further includes a third drive groove 33, and the crank 5 further includes a third protrusion 53 that slides along the third drive groove 33. The third drive groove 33 includes a sliding abutment section 332. When the third protrusion 53 slides to the sliding abutment section 332 of the third drive groove 33, the air guide plate 1 performs circumferential air delivery. Figure 32 As shown.

[0076] Optionally, the third drive groove 33 further includes a third end groove section 333 that is bent and connected to the sliding contact section 332. The air delivery angle formed by the air guide plate 1 when the third protrusion 53 of the crank 5 slides along the sliding contact section 332 is smaller than the air delivery angle formed by the air guide plate 1 when the crank 5 is in the third end groove section 333. As the third protrusion 53 of the crank 5 continues to slide along the sliding contact section 332, the air guide plate 1 is in a downward-opening air-guiding state. As the third protrusion 53 of the crank 5 continues to slide to the third end groove section 333, the downward-opening air-guiding angle of the air guide plate 1 gradually increases. Figure 33 and Figure 34 As shown.

[0077] Optionally, the crank 5 includes a first protrusion 51 that slides along the first drive groove 32 and a second protrusion 52 that slides along the second drive groove 42. The distance between the crank rotation center and the first protrusion 51 is a first rotation distance, and the distance between the crank rotation center and the second protrusion 52 is a second rotation distance. The first rotation distance is less than the second rotation distance.

[0078] The distance between the crank rotation center and the first protrusion 51 is the first rotational distance P1, and the distance between the crank rotation center and the second protrusion 52 is the second rotational distance P2, where P1 < P2. Thus, the difference in distance between the first and second protrusions 51 and the crank rotation center allows the crank 5 to drive the extension speeds of the first connecting rod 3 and the second connecting rod 4 to differ. Figure 12 and Figure 13 As shown.

[0079] Optionally, the crank 5 includes a first driving surface 501 and a second driving surface 502, wherein a first protrusion 51 is disposed on the first driving surface 501 and a second protrusion 52 is disposed on the second driving surface 502. The crank 5 is disposed between the first connecting rod 3 and the second connecting rod 4, wherein the first protrusion 51 is disposed on the first driving surface 501 of the crank 5 and the second protrusion 52 is disposed on the second driving surface 502 of the crank 5, so that the crank 5 can simultaneously drive the first connecting rod 3 and the second connecting rod 4 to extend during rotation.

[0080] Optionally, the first connecting rod 3 further includes a third drive groove 33, the second connecting rod 4 further includes a fourth drive groove 43, and the crank 5 further includes a third protrusion 53 sliding along the third drive groove 33 and a fourth protrusion 54 sliding along the fourth drive groove 43. The distance between the crank rotation center and the third protrusion 53 is the third rotation distance, the distance between the crank rotation center and the fourth protrusion 54 is the fourth rotation distance, and the third rotation distance is greater than the fourth rotation distance.

[0081] The distance between the crank rotation center and the third protrusion 53 is the third rotational distance P3, and the distance between the crank rotation center and the fourth protrusion 54 is the fourth rotational distance P4, where P3 > P4. Thus, the difference in distance between the third and fourth protrusions 53 and the crank rotation center allows for a difference in the extension speeds of the first connecting rod 3 and the second connecting rod 4 driven by the crank 5. Figure 12 and Figure 13 As shown.

[0082] Optionally, the third protrusion 53 is disposed on the first driving surface 501 of the crank 5, and the fourth protrusion 54 is disposed on the second driving surface 502 of the crank 5. Optionally, the surfaces of the first protrusion 51, the second protrusion 52, the third protrusion 53, and the fourth protrusion 54 are all fitted with bushings, which improves the smoothness of the protrusion sliding in the driving groove and reduces friction.

[0083] Optionally, the crank 5 includes a first extending arm 55 and a second extending arm 56, wherein a first protrusion 51 and a second protrusion 52 are disposed on the first extending arm 55, and a third protrusion 53 and a fourth protrusion 54 are disposed on the second extending arm 56. The first extending arm 55 and the second extending arm 56 of the crank 5 have different extending directions. The first protrusion 51 and the second protrusion 52 are respectively disposed on two opposite driving surfaces of the first extending arm 55, and the third protrusion 53 and the fourth protrusion 54 are respectively disposed on two opposite driving surfaces of the second extending arm 56.

[0086] Optionally, the depth of the second drive groove 42 is greater than the depth of the fourth drive groove 43. This allows the second protrusion 52, with a larger protrusion height, to slide along the deeper second drive groove 42, while the fourth protrusion 54, with a smaller protrusion height, can slide along the shallower fourth drive groove 43.

[0087] Optionally, a first sliding shaft 34 is provided at one end of the first link 3, and a driving part is provided at the other end of the first link 3.

[0088] Optionally, the drive structure further includes a first housing 6.

The first sliding shaft 34 and the second sliding shaft 35 of the first connecting rod 3 slide along the first sliding groove 61 simultaneously, which improves the motion stability of the first connecting rod 3 during its extension movement. Optionally, there is a certain distance between the first sliding shaft 34 and the second sliding shaft 35.

[0092] Optionally, the first housing 6 is provided with a crank slot 62 for engaging the crank 5.

Optionally, the first segment 36, the second segment 37, and the third segment 38 are integrally formed.

[0093] Optionally, the second segment 37 and the third segment 38 of the first connecting rod 3 are bent and connected. Optionally, the first segment 36 and the third segment 38 are parallel to each other. Optionally, the first segment 36, the third segment 38, and the first groove 61 are parallel to each other.

[0094] Optionally, the first tooth is disposed on the third segment 38 of the first link 3.

[0095] Optionally, the first tooth is straight and parallel to the first groove 61.

[0096] Optionally, a third sliding shaft 44 is provided at one end of the second connecting rod 4, and a second guide plate connecting end 41 is provided at the other end of the second connecting rod 4.

[0097] The drive structure also includes a second housing 7, which is provided with a second sliding groove 71. A third sliding shaft 44 slides along the second sliding groove 71. The second guide plate connecting end 41 of the second connecting rod 4 is rotatably connected to the rotating connecting piece 2 of the air guide plate 1, so that the second connecting rod 4 drives the air guide plate 1 to extend during movement. Figure 22 As shown.

[0098] The first housing 6 and the second housing 7 are interlocked to form a drive housing 92, in which the first connecting rod 3, the crank 5, and the second connecting rod 4 are disposed within the drive housing 92. The second housing 7 is provided with an inwardly recessed second sliding groove 71, along which the third sliding shaft 44 of the second connecting rod 4 slides. The second sliding groove 71 provides a motion trajectory for the second connecting rod 4 to perform telescopic movements, thereby improving the motion stability of the second connecting rod 4.

[0099] Optionally, the second slide 71 is linear. This allows the second connecting rod 4 to perform linear extension and retraction.

[0100] Optionally, the second link 4 is further provided with a fourth sliding shaft 45, and the second housing 7 is further provided with a third sliding groove 72, wherein the fourth sliding shaft 45 slides along the third sliding groove 72. The second link 4 is provided with both a third sliding shaft 44 and a fourth sliding shaft 45, which improves the motion stability of the second link 4.

[0101] Optionally, the third sliding shaft 44 and the fourth sliding shaft 45 are disposed on one side of the second connecting rod 4, and the second driving groove 42 and the fourth driving groove 43 are disposed on the other side of the second connecting rod 4.

[0102] Optionally, the second slide groove 71 and the third slide groove 72 are parallel to each other. For example, both the second slide groove 71 and the third slide groove 72 are straight slide grooves.

[0103] Optionally, the second slide groove 71 and the third slide groove 72 are offset. This can be understood as the starting points of the second slide groove 71 and the third slide groove 72 not being on the same horizontal line. This improves the stability of the second connecting rod 4 throughout its movement.

[0104] Optionally, the crank rotation center of crank 5 is configured to correspond to the second drive groove 42. For example... Figure 23 As shown, the projection of the crank rotation center falls into the second drive groove 42.

[0105] Optionally, the air guide plate 1 extends out and rotates around the pivot center of the rotating connector 2 under the drive of the first connecting rod 3 and the second connecting rod 4. Furthermore, during the rotation of the crank 5 in the first direction, the direction of rotation of the air guide plate 1 around the pivot center is first the same as the first direction, and then opposite to the first direction.

[0106] When crank 5 rotates in the first direction, the first connecting rod 3 and the second connecting rod 4 cause the air guide plate 1 to rotate in the same direction as the first direction. When crank 5 continues to rotate in the first direction, the rotation direction of the air guide plate 1 changes from the same direction as the first direction to the opposite direction. In this way, by making crank 5 rotate in the same direction, the rotation direction of the air guide plate 1 can be changed.

[0107] Optionally, in the first connecting rod 3, the third driving groove 33 is disposed above the first driving groove 32. Optionally, the first driving groove 32 and the third driving groove 33 are not connected to each other.

[0108] Optionally, in the second link 4, the fourth drive groove 43 is disposed above the second drive groove 42. Optionally, the second drive groove 42 and the fourth drive groove 43 are not connected to each other.

[0109] Optionally, when the direction of rotation of the air guide plate 1 around the pivot center is the same as the first direction, the first protrusion 51 and the second protrusion 52 of the crank 5 slide in the first drive groove 32 and the second drive groove 42, respectively. The second initial groove segment 421 of the first drive groove 32 and the second drive groove 42 are parallel to each other.

[0110] Optionally, the first drive groove 32 is perpendicular to the extension direction of the first connecting rod 3; alternatively, the second initial groove segment 421 of the second drive groove 42 is perpendicular to the extension direction of the first connecting rod 3.

[0111] Optionally, when the second protrusion 52 slides to the protruding section 422, the direction of rotation of the air guide plate 1 around the pivot center changes from being the same as the first direction to being opposite to the first direction. For example... Figure 31 and Figure 32 As shown.

[0112] Optionally, the first drive groove 32 includes a flared first drive end 3211, and the third drive groove 33 includes a third initial groove segment 331 and a sliding abutment segment 332.

When the first protrusion 51 slides to the first drive end 3211, the third protrusion 53 slides to the third bending groove point. Figure 31 As shown, at this time, the air guide plate is in its maximum upward air guiding state.

[0113] Optionally, when the second protrusion 52 slides to the protrusion 422, the first protrusion 51 slides to the first driving end 3211. For example... Figure 31 As shown.

[0114] Optionally, the fourth drive groove 43 includes a fourth initial groove segment 431 and a fourth end groove segment 432, wherein when the second protrusion 52 slides to the protrusion segment 422, the fourth protrusion 54 begins to enter the fourth initial groove segment 431. Figure 31 As shown.

[0115] This disclosure also provides an indoor air conditioning unit.

[0116] Optionally, the indoor unit of the air conditioner includes an air guide plate 1, a first link 3, and a second link 4.

[0117] The air guide plate 1 includes an air guide plate body and a mounting base disposed on the air guide plate body. The mounting base includes a mounting base body 12 and a rotating connector 2 disposed on the mounting base body 12. The mounting base body 12 includes a first mounting plate portion 121 with the rotating connector 2 and a first tooth-blocking plate portion 122 extending along the first mounting plate portion 121. The first tooth-blocking plate portion 122 is used to block the first tooth portion. The mounting base is disposed on the air guide plate body and is used to mount a drive assembly that drives the air guide plate 1 to extend and rotate. The rotating connector 2 is disposed on the mounting base body 12.

[0118] During the rotation of the air guide plate body, the first tooth will form different angles with the air guide plate body. In this embodiment, the mounting base body 12 is provided with a first tooth-shielding plate 122, which can shield the first tooth and improve the aesthetic performance of the air conditioner indoor unit.

[0119] Optionally, the rotating connector 2 includes a second tooth 21 that meshes with the first tooth. When the air guide plate 1 is in the closed state, the second tooth 21 includes a meshing end that meshes with the first tooth. The first mounting plate portion 121 of the mounting base body 12 includes a first mounting side 1211 near the meshing end and a second mounting side 1212 opposite to the first mounting side 1211. Furthermore, the first tooth-shielding plate portion 122 is disposed on the first mounting side 1211 of the first mounting plate portion 121. Figure 28 As shown.

[0120] The first tooth-shielding plate portion 122 is disposed on the first mounting side 1211 near the meshing end, which improves the shielding effect of the first tooth-shielding plate portion 122 on the first tooth portion.

[0121] Optionally, the first mounting plate portion 121 and the first tooth-shielding plate portion 122 are integrally formed.

[0122] Optionally, the first shielding plate portion 122 includes a first shielding tooth top edge 1221 located at the top, and the first tooth portion includes a first engaging tooth located away from the air guide plate body, wherein when the air guide plate 1 is in the closed state, the first shielding tooth top edge 1221 blocks the first engaging tooth. Figure 28 As shown.

[0123] When the air guide plate 1 is in the closed state, the first shielding plate portion 122 blocks the first tooth portion in the height direction. In this embodiment of the present disclosure, the top edge 1221 of the first shielding tooth exceeds the first meshing tooth in the height direction, so that the top edge 1221 of the first shielding tooth blocks the first meshing tooth, thereby improving the shielding effect of the first shielding plate portion 122 on the first tooth portion.

[0124] Optionally, the first tooth-shielding plate portion 122 includes a first tooth-shielding side edge 1222 located on the side, wherein when the air guide plate 1 is at its maximum upward opening air guiding angle, the first tooth-shielding side edge 1222 blocks the first meshing tooth. For example... Figure 31 As shown.

[0125] When the air guide plate 1 is at its maximum upward opening angle, the width of the first shielding plate portion 122 acts as a shield for the first tooth portion. In this embodiment, the width of the first shielding plate portion 122 exceeds the first meshing tooth, so that the side edge 1222 of the first shielding tooth blocks the first meshing tooth, thereby improving the shielding effect of the first shielding plate portion 122 on the first tooth portion.

[0126] Optionally, the first mounting plate portion 121 includes a first snap-fit ​​lug 123, and the second tooth portion 21 of the rotating connector 2 includes a first snap-fit ​​boss 213 that snaps into the first snap-fit ​​lug 123.

[0127] The second tooth 21 has a through hole, and the first snap-fit ​​boss 213 is provided at the through hole on the inner side of the second tooth 21, so as to snap the rotating connector 2 onto the first mounting plate 121.

[0128] Optionally, the second tooth 21 is a gear, wherein the engagement center of the first engagement boss 213 overlaps with the gear center of the second tooth 21. This improves the accuracy of the meshing between the second tooth 21 and the first tooth, so that the meshing between the second tooth 21 and the first tooth is directly reflected in the rotation of the air guide plate.

[0129] Optionally, the second tooth 21 includes a top edge 2101 and a bottom edge 2102. The rotating connector 2 includes a connecting seat 22 with the second tooth 21. The connecting seat 22 includes a top edge 2201 and a bottom edge 2202. The distance between the top edge 2101 and the top edge 2201 is a top reserved distance, and the distance between the bottom edge 2102 and the bottom edge 2202 is a bottom reserved distance. The top reserved distance is smaller than the bottom reserved distance.

[0130] The top clearance between the toothed top edge 2101 and the top edge 2201 of the connecting seat is relatively small, thus reducing the size of the rotating connector 2. The bottom clearance between the toothed bottom edge 2102 and the bottom edge 2202 of the connecting seat is relatively large, thus providing sufficient space for the relative rotation between the air guide plate 1 and the second connecting rod 4.

[0131] Optionally, the rotating connector 2 includes a second tooth 21 that meshes with the first tooth, and the second guide plate connecting end 41 of the second connecting rod 4 is further provided with a tooth-shielding sleeve 47, wherein the second tooth 21 is disposed within the tooth-shielding sleeve 47. Figure 17 As shown. This improves the shielding effect on the second tooth 21.

[0132] Optionally, a rotation clearance is provided between the inner wall of the tooth-shielding sleeve 47 and the outer edge of the second tooth 21. This prevents the inner wall of the tooth-shielding sleeve 47 from wearing with the second tooth 21 during rotation, thereby improving the rotational stability of the second tooth 21.

[0133] Optionally, the tooth-covering sleeve 47 is provided with a rotation opening 471, wherein a portion of the teeth of the second tooth 21 is exposed at the rotation opening 471, so that the second tooth 21 meshes with the first tooth of the first connecting rod 3. Figure 5 As shown. Part of the second tooth 21 is exposed at the rotation opening 471, so that the part of the second tooth 21 exposed at the rotation opening 471 can mesh with the first tooth.

[0134] Optionally, the tooth-shielding sleeve 47 is disposed outside the sleeve through groove 411.

[0135] Optionally, the rotating connector 2 includes a second tooth 21 that meshes with the first tooth. The second guide plate connecting end 41 of the second connecting rod 4 is further provided with a receiving end 412, and a rack receiving groove 48 is formed inside the receiving end 412. The rack receiving groove 48 is used to receive the first tooth during the extension process. During the meshing process between the first tooth and the second tooth 21, the meshing position of the first tooth and the second tooth 21 changes. The rack receiving groove 48 is used to receive the first tooth during the extension process, which improves the shielding effect on the first tooth.

[0136] Optionally, the extending direction of the rack receiving groove 48 is the same as the extending direction of the first tooth.

[0137] Optionally, the rack receiving groove 48 has a first rack receiving length. When the air guide plate 1 is in the closed state, the first tooth includes an initial meshing section 311 that meshes with the second tooth section 21 and a first tooth section 312 and a second tooth section 313 located at both ends of the initial meshing section 311. The first tooth section 312 is disposed close to the air guide plate 1. The first rack receiving length is greater than or equal to the sum of the lengths of the initial meshing section 311 and the first tooth section 312.

[0138] When the air guide plate 1 is in the downward-opening air guiding state, the second tooth segment 313 of the first tooth part meshes with the second tooth part 21. At this time, the first rack accommodating length Z1 is greater than or equal to the sum of the lengths of the initial meshing segment 311 and the first tooth segment 312, improving the accommodating effect of the rack accommodating groove 48 on the first tooth part during the extension and retraction process. Alternatively, the length Z2 of the end of the rack accommodating groove 48 is greater than or equal to the sum of the lengths of the initial meshing segment 311 and the first tooth segment 312. Figure 33 As shown.

[0139] Optionally, the second guide plate connecting end 41 of the second connecting rod 4 is further provided with a tooth-shielding cover plate 49 connected to the receiving end. For example... Figure 35 As shown. The tooth-shielding cover 49 reduces the size of the mounting base body 12; for example, the first tooth-shielding plate portion may not be required. At the same time, it reduces the size of the cover opening to prevent foreign objects from entering.

[0140] Optionally, the tooth cover plate 49 is engaged with the receiving end of the second connecting rod 4 to form a receiving cavity for blocking the first rack. In this way, the first connecting rod 3 can be slidably abutted and limited during the extension and retraction process, which improves the meshing effect between the first tooth and the second tooth 21 of the first connecting rod 3 and prevents tooth dislodgement.

[0141] Optionally, the rack receiving groove 48 includes a sliding stop flange 481 corresponding to the rotation opening 471, and the first guide plate connecting end 31 of the first connecting rod 3 includes an extended abutting edge opposite to the first rack, wherein the extended abutting edge of the first connecting rod 3 slides against the sliding stop flange 481 of the rack receiving groove 48. Figure 25 As shown, the sliding stop flange 481 is used to slide against the first connecting rod 3 during the extension and retraction process. This improves the meshing effect between the first tooth and the second tooth 21 of the first connecting rod 3 and prevents tooth disengagement. Optionally, the sliding stop flange 481 is parallel to the first tooth.

[0142] Optionally, the indoor unit of the air conditioner includes a housing 8, an air guide plate drive mechanism, and an electrical control box 91.

[0143] The housing 8 includes a first sidewall 81; the air guide plate drive mechanism is used to drive the air guide plate 1 to extend and rotate. The air guide plate drive mechanism is disposed inside the housing 8 and includes a drive box 92 and a first connecting rod 3, a second connecting rod 4 and a crank 5 disposed inside the drive box 92. The electrical control box 91 is disposed inside the housing 8.

[0144] The drive housing 92 and the control housing 91 are disposed on the inner wall of the first side wall 81, and the drive housing 92 is disposed below the control housing 91.

[0145] The existing drive box and electrical control box are arranged side by side along the length of the indoor unit of the air conditioner.

[0146] In this embodiment, the drive housing 92 is disposed below the electrical control housing 91, reducing the space occupied by the drive housing 92 in the length direction of the air conditioner indoor unit, which is beneficial to reducing the size of the air conditioner indoor unit in the length direction. Thus, while achieving multiple air supply modes, it is beneficial to achieve miniaturization of the air conditioner indoor unit.

[0147] Optionally, the electrical control box 91 includes an electrical control bottom shell 911 located at the bottom, and the drive box 92 includes a drive top shell located at the top, wherein the drive top shell is located directly below the electrical control bottom shell 911. This arrangement ensures that the electrical control box 91 and the drive housing 8 are positioned adjacent to each other, preventing mutual interference when either the drive box 92 or the electrical control box 91 needs repair or replacement, thus improving maintenance convenience.

[0148] Optionally, the electronic control box 91 includes an electronic control rear shell located at the rear, the drive box 92 includes a drive rear shell located at the rear, and the housing 8 includes a first rear shell 82. The distance between the electronic control rear shell and the first rear shell 82 is the electronic control rear distance, the distance between the drive rear shell and the first rear shell 82 is the drive rear distance, and the electronic control rear distance is less than the drive rear distance.

[0149] like Figure 27 As shown, the distance Y1 after the electronic control is less than the distance Y2 after the drive is. This makes the electronic control box 91 positioned further back in the indoor unit of the air conditioner, while the drive box 92 positioned further forward in the indoor unit of the air conditioner. This is beneficial for the drive box 92 to exert its driving effect on the air guide plate 1.

[0150] Optionally, the electronic control box 91 includes an electronic control front shell located at the front, the drive box 92 includes a drive front shell located at the front, and the housing 8 includes a first front shell. The distance between the electronic control front shell and the first front shell is the electronic control front distance, the distance between the drive front shell and the first front shell is the drive front distance, and the electronic control front distance is greater than the drive front distance.

[0151] The distance Y3 before the electronic control is greater than the distance Y4 before the drive, which makes the drive box 92 positioned further forward in the indoor unit of the air conditioner, which is beneficial for the drive box 92 to exert its driving effect on the air guide plate 1.

[0152] Optionally, the height of the electrical control box 91 is the first electrical control height, and the height of the drive box 92 is the first drive height, wherein the first electrical control height is greater than the first drive height.

[0153] The height Y5 of the first electrical control unit is greater than the height Y6 of the first drive unit. Compared to the electrical control unit 91, the drive unit 92 has a relatively smaller height, meaning the overall volume of the drive mechanism is relatively small. This allows the drive unit 92 to drive the air guide plate 1 without requiring a large volume, which is beneficial for miniaturizing the indoor unit of the air conditioner.

[0154] This disclosure also provides an air conditioner, including the indoor unit as described above.

[0155] Optionally, the air conditioner includes the drive mechanism, drive device, or drive structure as described above.
