Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, such as a drive mechanism for an air guide vane and an air conditioner. Background Technology

For example, the drive mechanism includes a drive motor, a first link, and a second link. One end of the first link and the second link are driven by the drive motor, and the other end is connected to the air guide plate, so that the first link and the second link can drive the air guide plate to rotate.

[0004] The existing air guide plate drive mechanism is prone to jamming during the rotation of the air guide plate, which affects the air guiding effect of the air guide plate.

[0026] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0028] This disclosure provides a driving mechanism for an air guide plate, which can also be referred to as a driving structure.

[0029] Optionally, the drive mechanism includes an extension link 1 and a rotation link 2.

[0030] The extension link 1 moves under the drive of the drive element 3, including a first connecting end 11 connected to the connecting member 41 of the air guide plate, and the first connecting end 11 is pivotally connected to the connecting member 41.

[0031] The rotating link 2 moves under the drive of the drive element 3, including a second connecting end 21 connected to the connecting member 41 of the air guide plate, and the second connecting end 21 is driven to connect with the connecting member 41.

[0032] The extension link 1 is provided with an extension link track 12, and the drive element 3 includes a first drive shaft 31 that slides along the extension link track 12. When the air guide plate opens in the first direction and the second direction, the first drive shaft 31 slides along the extension link track 12.

[0033] In the driving mechanism provided in this embodiment, the rotating link 2 is driven to connect with the connecting member 41 of the air guide plate to drive the air guide plate to rotate, thereby improving the smoothness of the air guide plate rotation process and avoiding the problem of the air guide plate getting stuck; the extending link 1 is pivotally connected to the connecting member 41 of the air guide plate to drive the air guide plate to extend.

[0034] In this way, there is no problem of a fixed distance between the two shafts of the two connecting rods. Even if the actual production drive mechanism deviates from the design scheme, the air guide plate will not get stuck during rotation, and the first connecting end 11 of the extended connecting rod 1 will not be worn.

[0035] As can be seen, the driving mechanism provided in this embodiment improves the stability of the air guide plate driving process. Furthermore, the driving mechanism provided in this embodiment eliminates the fixed distance between the two rotating shafts, thus allowing the rotating link 2 and the extending link 1 to achieve the rotation of the air guide plate without extending a large distance, reducing the size of the driving mechanism and the space it occupies in the air conditioner indoor unit.

[0036] The second connecting end 21 of the rotating link 2 is driven to connect with the connecting member 41. This can be understood as meaning that the second connecting end 21 of the rotating link 2 and the connecting member 41 do not need to be equipped with an active driving power such as a motor, but the driving connection is achieved through the meshing between teeth.

[0037] The connector 41 provides a connection point for the connection between the rotating link 2 and the extending link 1 and the air guide plate. Optionally, the connector 41 of the air guide plate can be part of the air guide plate body 4, or it can be a separate component disposed on the air guide plate body 4. Optionally, the connector 41 is integrally formed with the air guide plate body 4; or, the connector 41 is snapped into the air guide plate body 4, etc. Optionally, the connector 41 is perpendicular to the air guide plate body 4.

[0038] Optionally, the drive element 3 includes a crank that rotates under the drive of a motor, thereby causing the extension connecting rod 1 and the rotating connecting rod 2 to extend or retract.

[0039] If the extending link has two or more tracks, the drive shaft of the drive element needs to slide out of one track and then into another track to enable the drive element to drive the movement of the extending link. However, during the process of the drive shaft sliding in and out of multiple tracks, problems such as motion errors and drive shaft derailment can easily occur, affecting the driving stability of the drive mechanism.

[0040] In this embodiment, the extending connecting rod 1 is provided with an extending rod track 12. When the driving mechanism drives the air guide plate to open in the first direction and in the second direction, the first driving shaft 31 of the driving element 3 slides along the extending rod track 12. In this way, the first driving shaft 31 does not need to slide out of the extending rod track 12. Optionally, both ends of the extending rod track 12 are closed, that is, neither end of the extending rod track 12 is open. When the first driving shaft 31 slides to the end of the extending rod track 12, it can also be stopped by the end, avoiding the problem of the first driving shaft 31 sliding out of the track and causing instability of the driving mechanism.

[0041] Optionally, the air guide plate can open upwards in the first direction, for example, in cooling mode; and it can open downwards in the second direction, for example, in heating mode.

[0042] Optionally, the extendable rod track 12 is arc-shaped; or, the extendable rod track 12 includes multiple straight segments connected by bends. For example... Figure 2 and Figure 3 As shown.

[0043] When the extension rod track 12 is arc-shaped, the whole structure forms a smooth concave arc groove.

[0044] When the extension rod track 12 consists of multiple straight segments connected by bends, the extension rod track 12 is composed of an upper inclined straight groove, a middle inclined straight groove, and a lower inclined straight groove that are smoothly connected end to end by bends. The inclination angle of the straight segments increases sequentially, and the joints between two adjacent straight segments are rounded to improve the smoothness and stability of the first drive shaft 31 sliding within the extension rod track 12, preventing jamming.

[0045] Optionally, the extension rod track 12 includes a first track end 121 and a second track end 122 located at both ends. When the air guide plate is in the closed state, the first drive shaft 31 is located at the first track position 123 of the extension rod track 12. The movement path formed by the first drive shaft 31 moving from the first track position 123 to the first track end 121 is the first movement path. The movement path formed by the first drive shaft 31 moving from the first track end 121 to the first track position 123 is the second movement path. The movement path formed by the first drive shaft 31 moving from the first track position 123 to the second track end 122 is the third movement path. When the first drive shaft 31 moves along the first movement path and the second movement path in sequence, the air guide plate opens in the first direction. When the first drive shaft 31 moves along the third movement path, the air guide plate opens in the second direction.

[0046] like Figures 6 to 9 As shown, where, Figure 8 and Figure 9The first track groove of the extension rod track 12 is marked as A1, the first track end 121 is marked as A2, the second track end 122 is marked as A3, the motion path formed from A1 to A2 is the first motion path, the motion path formed from A2 to A1 is the second motion path, and the motion path formed from A1 to A3 is the third motion path.

[0047] When the first drive shaft 31 moves sequentially from A1 to A2 and then from A2 back to A1, the air guide plate opens in the first direction. This reciprocating motion of the first drive shaft 31 between A1 and A2 achieves the opening of the air guide plate in the first direction. When the first drive shaft 31 moves from A1 to A3, the air guide plate opens in the second direction. Thus, when the air guide plate opens in the first direction and the second direction, the first drive shaft 31 has relatively independent sliding ranges within the extension rod track 12, without interference.

[0048] Optionally, the first track end 121 is the upper end of the extension rod track 12, and the second track end 122 is the lower end of the extension rod track 12.

[0049] When the drive mechanism is installed on the air conditioner and the air guide plate is closed, the first track end 121 of the extension rod track 12 is located above the second track end 122.

[0050] Optionally, the distance between the first track position 123 and the first track end 121 is SL1, and the distance between the first track position 123 and the second track end 122 is SL2, wherein SL1 < SL2.

[0051] It is understood that SL1 is the length of the movement path of the first drive shaft 31 from the first track position 123 to the first track end 121; similarly, SL2 is the length of the movement path of the first drive shaft 31 from the first track position 123 to the second track end 122. In this embodiment of the present disclosure, the first drive shaft 31 achieves the maximum angle of opening the air guide plate in the first direction with a relatively short movement stroke.

[0052] Optionally, the connecting member 41 of the air guide plate has a guide plate rotation center 401, the distance between the first track end 121 and the guide plate rotation center 401 is SL3, and the distance between the second track end 122 and the guide plate rotation center 401 is SL4, wherein SL3 < SL4.

[0053] The connecting part 41 of the air guide plate includes a rotating gear, and the center of rotation 401 of the air guide plate is the center of the rotating gear. Figure 7As shown. When the drive mechanism is installed on the air conditioner or the indoor unit of the air conditioner and the air guide plate is in the closed state, SL3 < SL4, that is, the extension rod track 12 is approximately concave arc or multi-segment shape from the first track end 121 to the second track end 122, and the rotation center 401 of the guide plate is on the concave side.

[0054] Optionally, the horizontal line passing through the first track end 121 is the first horizontal line, wherein the angle between the extended rod track 12 and the first horizontal line gradually increases from the first track end 121 to the second track end 122.

[0055] When the extension rod track 12 is arc-shaped, the angle between different positions of the extension rod track 12 and the first horizontal line L1 is the angle formed by the external tangent of that position and the first horizontal line L1, such as... Figure 9 As shown; when the extension rod track 12 is multi-segmented, the angle between the extension rod track 12 at different positions and the first horizontal line L1 is the angle between the straight line segment at that position and the first horizontal line L1.

[0056] In this embodiment of the present disclosure, the angle between the extension rod track 12 and the first horizontal line L1 gradually increases from the first track end 121 to the second track end 122, so that the extension rod track 12 extends downward in a shape that is generally curved downward from A2 to A3, and the transition is smooth.

[0057] Optionally, the angle between the first track end 121 of the extension rod track 12 and the first horizontal line L1 is a1, and the angle between the second track end 122 of the extension rod track 12 and the first horizontal line L1 is a2, wherein the difference between a2 and a1 is greater than or equal to 10° and less than 70°.

[0058] The angle a2 between the second track end 122 and the first horizontal line L1 is greater than the angle a1 between the first track end 121 and the first horizontal line L1. Optionally, the difference between a2 and a1 can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, or 65°, etc.

[0059] Optionally, the angle α1 between the first track end 121 and the first horizontal line L1 is greater than or equal to 40° and less than or equal to 60°.

[0060] For example, a1 can be 40°, 42°, 45°, 47°, 50°, 53°, 55°, 57° or 60°.

[0061] Optionally, the angle a2 between the second track end 122 and the first horizontal line L1 is greater than or equal to 70° and less than or equal to 90°.

[0062] For example, a2 can be 70°, 72°, 75°, 77°, 80°, 83°, 85°, 87° or 90°.

[0063] Optionally, the driving element 3 further includes a second driving shaft 32 that slides along the rotating rod track 22 of the rotating link 2, and the driving element 3 has a driving rotation center 33, wherein the distance between the driving rotation center 33 and the first driving shaft 31 is R1, the distance between the driving rotation center 33 and the second driving shaft 32 is R2, and R1 and R2 are not equal.

[0064] Optionally, the drive element 3 includes a crank, and both the first drive shaft 31 and the second drive shaft 32 rotate around the drive rotation center 33. Furthermore, the distance R1 between the drive rotation center 33 and the first drive shaft 31 is not equal to the distance R2 between the drive rotation center 33 and the second drive shaft 32. This results in different extension speeds for the extension link 1 and the rotating link 2 driven by the drive element 3, creating a speed difference between them. Consequently, the extension link 1 and the rotating link 2 drive the air guide plate to open in either the first direction or the second direction.

[0065] Optionally, R1 > R2. For example... Figure 21 As shown.

[0066] Optionally, the drive rotation center 33, the first drive shaft 31, and the second drive shaft 32 are located on the same straight line.

[0067] Optionally, the driving element 3 includes a first driving surface and a second driving surface disposed opposite to each other, wherein the first driving shaft 31 is disposed on the first driving surface, and the second driving shaft 32 is disposed on the second driving surface. The second driving projection of the second driving shaft 32 is obtained by projecting it perpendicularly onto the first driving surface. The fact that the driving rotation center 33, the first driving shaft 31, and the second driving shaft 32 are located on the same straight line can also be understood as the driving rotation center 33, the first driving shaft 31, and the second driving projection being located on the same straight line. Figure 22 As shown.

[0068] In this embodiment, the driving rotation center 33 of the driving element 3, the first driving shaft 31 and the second driving shaft 32 are located on the same straight line. This facilitates the design calculation of the driving extension distance of the driving element 3 to the extension link 1 and the rotating link 2, and the rotation angle of the air guide plate.

[0069] Optionally, the rotating link 2 is provided with a rotating rod track 22, and the driving element 3 includes a second driving shaft 32 that slides along the rotating rod track 22. When the air guide plate opens in the first direction or the second direction, the second driving shaft 32 slides along the rotating rod track 22.

[0070] Similarly, if the rotating linkage has two or more tracks, the drive shaft of the driving element needs to slide out of one track and then into another track to enable the driving element to drive the rotation of the rotating linkage. However, during the sliding in and out process of the drive shaft, problems such as motion errors and the drive shaft deviating from the track can easily occur, affecting the driving stability of the driving mechanism.

[0071] In this embodiment, the rotating linkage 2 is provided with a rotating rod track 22. When the driving mechanism drives the air guide plate to open in the first direction and the second direction, the second driving shaft 32 of the driving element 3 slides along the rotating rod track 22. Thus, when the air guide plate opens in the first direction and the second direction, the second driving shaft 32 slides within the rotating rod track 22, and the second driving shaft 32 does not need to slide out of the rotating rod track 22. Optionally, both ends of the rotating rod track 22 are closed, that is, neither end of the rotating rod track 22 is open. This way, when the second driving shaft 32 slides to the end of the rotating rod track 22, it is stopped by the end, preventing the driving shaft from sliding out of the track and causing instability in the driving mechanism.

[0072] Optionally, the second connecting end 21 of the rotating link 2 includes a rack segment, and the connecting member 41 of the air guide plate includes a rotating gear, wherein the rack segment is meshed with the rotating gear.

[0073] The rack segment of the rotating link 2 meshes with the rotating gear of the air guide plate, thereby achieving a driving connection between the second connecting end 21 of the rotating link 2 and the connecting piece 41 of the air guide plate. The meshing of the rack segment with the rotating gear drives the rotating gear to rotate. The rotating gear is fixedly connected to the air guide plate body 4, and the rotation of the rotating gear causes the air guide plate body 4 to rotate synchronously, enabling the air guide plate to open in either the first or second direction. Furthermore, the meshing of the rack segment of the rotating link 2 with the rotating gear facilitates the stable stopping of the air guide plate at any angle.

[0074] Optionally, the rotating rod track 22 includes a third track end 221 and a fourth track end 222 located at both ends. When the air guide plate is in the closed state, the second drive shaft 32 is located at the second track position 223 of the rotating rod track 22. The movement path formed by the second drive shaft 32 moving from the second track position 223 to the third track end 221 is the fourth movement path, the movement path formed by the second drive shaft 32 moving from the third track end 221 to the second track position 223 is the fifth movement path, and the movement path formed by the second drive shaft 32 moving from the second track position 223 to the fourth track end 222 is the sixth movement path. When the second drive shaft 32 moves along the fourth and fifth movement paths in sequence, the air guide plate opens in the first direction; when the second drive shaft 32 moves along the sixth movement path, the air guide plate opens in the second direction.

[0075] like Figures 16 to 18 As shown, where, Figure 17 and Figure 18 The second track groove of the rotating rod track 22. The position 223 of the second track is marked as B1, the end 221 of the third track is marked as B2, the position 222 of the fourth track is marked as B3, the motion path formed by the second drive shaft 32 from B1 to B2 is the fourth motion path, the motion path formed from B2 to B1 is the fifth motion path, and the motion path formed from B1 to B3 is the sixth motion path.

[0076] When the second drive shaft 32 moves sequentially from B1 to B2 and then from B2 back to B1, the air guide plate opens in the first direction. This causes the second drive shaft 32 to reciprocate between B1 and B2, thus opening the air guide plate in the first direction. When the second drive shaft 32 moves from B1 to B3, the air guide plate opens in the second direction. Therefore, when the air guide plate opens in the first direction and the second direction, the second drive shaft 32 has relatively independent sliding ranges within the rotating rod track 22, without interference.

[0077] Optionally, the third track end 221 is the upper end of the rotating rod track 22, and the fourth track end 222 is the lower end of the rotating rod track 22.

[0078] When the drive mechanism is installed on the air conditioner or the indoor unit of the air conditioner and the air guide plate is closed, the third track end 221 of the rotating rod track 22 is located above the fourth track end 222.

[0079] Optionally, the connecting member 41 of the air guide plate has a guide plate rotation center 401, the distance between the third track end 221 and the guide plate rotation center 401 is XL1, the distance between the fourth track end 222 and the guide plate rotation center 401 is XL2, and the distance between the second track position 223 and the guide plate rotation center 401 is XL3, wherein XL1 > XL3, and XL2 > XL3.

[0080] The distance XL1 between the third track end 221 and the center of rotation 401 of the guide plate is greater than the distance XL3 between the second track position 223 and the center of rotation 401 of the guide plate. Furthermore, the distance XL2 between the fourth track end 222 and the center of rotation 401 of the guide plate is also greater than the distance XL3 between the second track position 223 and the center of rotation 401 of the guide plate. Figure 19 As shown, the rotating rod track 22 is roughly in the shape of a "√", and the second track position 223 is roughly located at the bend on one side of the guide plate rotation center 401 of the rotating rod track 22, that is, the second track position 223 is roughly located at the bend of the "√" shape.

[0081] Optionally, the distance between the second track position 223 and the third track end 221 is XL4, and the distance between the second track position 223 and the fourth track end 222 is XL5, wherein XL4 < XL5.

[0082] It is understood that XL4 is the length of the movement path of the second drive shaft 32 from the second track position 223 to the third track end 221; similarly, XL5 is the length of the movement path of the second drive shaft 32 from the second track position 223 to the fourth track end 222. In this embodiment of the present disclosure, the second drive shaft 32 achieves the maximum angle at which the air guide plate opens in the first direction with a relatively short movement stroke.

[0083] Optionally, the first rotating track segment of the rotating rod track 22 is located between the third track end 221 and the second track position 223. The horizontal line passing through the third track end 221 is the second horizontal line L2, and the angle between the first rotating track segment and the second track position 223 and the second horizontal line L2 gradually increases from the third track end 221.

[0084] Define the first rotating track segment between the third track end 221 and the second track position 223 of the rotating rod track 22. Draw a second horizontal line L2 through the third track end 221. The angle between the third track end 221 and the second horizontal line is a3. The angle between the second track position 223 and the second horizontal line is a4. Furthermore, a4 > a3.

[0085] Optionally, the first rotating track segment is an arc segment.

[0086] like Figure 18 As shown, when the first rotating track segment is an arc segment, the external tangent of the third track end 221 is drawn. At this time, the angle a3 between the third track end 221 and the second horizontal line L2 is the angle between the external tangent of the third track end 221 and the second horizontal line L2. The external tangent of the second track position 223 is drawn. At this time, the angle a4 between the second track position 223 and the second horizontal line L2 is the angle between the external tangent of the second track position 223 and the second horizontal line L2. In this embodiment of the present disclosure, the first rotating track segment is approximately a concave arc-shaped track segment.

[0087] Optionally, the extension rod 1 is provided with an extension rod track 12, and the driving element 3 includes a first drive shaft 31 that slides along the extension rod track 12. When the air guide plate opens in the first direction and the second direction, the first drive shaft 31 slides along the extension rod track 12. The extension rod track 12 includes a first track end 121 and a second track end 122 located at both ends. The horizontal line passing through the first track end 121 is the first horizontal line L1, wherein the first horizontal line L1 is located above the second horizontal line L2.

[0088] like Figure 20 As shown, when the air guide plate is in the closed state, the first horizontal line L1 passing through the first track end 121 is located above the second horizontal line L2 passing through the third track end 221. This embodiment of the disclosure provides the vertical positional relationship between the first track end 121 of the extension rod track 12 and the third track end 221 of the rotating rod track 22 in the initial state.

[0089] Optionally, the drive mechanism includes a drive element 3.

[0090] The drive element 3 rotates under the drive of the motor. The drive element 3 includes a first drive shaft 31 and a second drive shaft 32.

[0091] The drive mechanism also includes a first track plate 5 and a second track plate 6. The first track plate 5 is provided with a first slide groove 51, and the second track plate 6 is provided with a second slide groove 61.

[0092] The first protruding rod surface of the extending connecting rod 1 is provided with a first sliding post 13 that slides along the first sliding groove 51, and the first rotating rod surface of the rotating connecting rod 2 is provided with a second sliding post 23 that slides along the second sliding groove 61.

[0093] Optionally, the first chute 51 includes a first initial chute segment, and the second chute 61 includes a second initial chute segment, wherein the first initial chute segment and the second initial chute segment are concentric circular arcs.

[0094] When the air guide plate is in the closed state, the first sliding post 13 of the extended connecting rod 1 is located at the first initial end of the first slide groove 51, and the second sliding post 23 of the rotating connecting rod 2 is located at the second initial end of the second slide groove 61. It can be understood that the first initial groove segment of the first slide groove 51 is a portion of the first slide groove 51 starting from the first initial end; similarly, the second initial groove segment of the second slide groove 61 is a portion of the second slide groove 61 starting from the second initial end.

[0095] In this embodiment of the disclosure, the first initial slot segment and the second initial slot segment are concentric circular arcs.

[0096] Optionally, the connecting member 41 of the air guide plate has a guide plate rotation center 401. When the first sliding column 13 of the extended connecting rod 1 slides along the first initial groove segment and the second sliding column 23 of the rotating connecting rod 2 slides along the second initial groove segment, the motion trajectory formed by the guide plate rotation center 401 is the guide plate center motion trajectory, wherein the guide plate center motion trajectory is a concentric arc with the first initial groove segment and the second initial groove segment.

[0097] It is understood that the trajectory of the guide plate's center of motion is a virtual trajectory formed by the rotation center 401 of the guide plate. In this embodiment of the present disclosure, the trajectory of the guide plate's center of motion is a concentric arc with the first initial groove segment and the second initial groove segment.

[0098] Optionally, when the first sliding post 13 of the extended connecting rod 1 slides along the first initial groove segment, the first sliding post 13 moves from position C1 to position C2 of the first initial groove segment, and the rotation center 401 of the guide plate moves from position E1 to position E2. The center of the circle containing the arc with the same center is H, where ∠C1HC2=∠E1HE2.

[0099] like Figure 40 As shown, the first initial end of the first initial groove segment is marked as position C1, the end of the first initial groove segment is marked as position C2, and the end of the first slide 51 is marked as C3. When there are two first slides 51, the positions C4, C5, and C6 of the other first slide 51 correspond to C1, C2, and C3, respectively.

[0100] The second initial end of the second initial groove segment is marked as position D1, the end of the second initial groove segment is marked as position D2, and the end of the second slide 61 is marked as D3. When there are two second slides 61, the positions D4, D5, and D6 of the other second slide 61 correspond to D1, D2, and D3, respectively.

[0101] The center of the circle containing the arc of the guide plate's circular motion trajectory and the concentric arc of the first and second initial groove segments is H. It is understandable that, due to the large size of this circle... Figure 40 The center point H is not displayed. Figure 40 The center H of the circle is the point where the four lines passing through points A1, A11, B1, and B11 intersect after being extended.

[0102] It is understandable that E1 indicates the air guide plate is in the closed state, i.e. Figure 40 Position 1 of the middle air guide plate is the location of the center of rotation 401 of the guide plate. E2 is the position when the air guide plate is opened to its maximum angle in the first direction, i.e. Figure 40 Position 3 of the middle air guide plate is the location of the rotation center 401 of the guide plate. In this embodiment of the disclosure, ∠C1HC2=∠E1HE2.

[0103] Optionally, when the first drive shaft 31 of the drive element 3 moves from position A1 to position A11, the first drive shaft 31 drives the first sliding column 13 of the extended connecting rod 1 to slide along the first initial groove segment, so that the first sliding column 13 moves from position C1 of the first initial groove segment to position C2, where ∠A1HA11=∠C1HC2.

[0104] Thus, ∠A1HA11=∠C1HC2=∠E1HE2. During the rotation of the air guide plate driven by the drive mechanism, the maximum opening angle of the air guide plate in the first direction can be set according to the specific air guiding requirements of the indoor air conditioning unit. Therefore, the rotation of the drive element 3 of the drive mechanism can be calculated based on ∠E1HE2.

[0105] Optionally, when the second drive shaft 32 of the drive element 3 moves from position B1 to position B11, the second drive shaft 32 drives the second sliding column 23 of the rotating link 2 to slide along the second initial groove segment, so that the second sliding column 23 moves from position D1 of the second initial groove segment to position D2, where ∠B1HB11=∠D1HD2.

[0106] Alternatively, ∠A1HA11 is not equal to ∠B1HB11.

[0107] A1-A11 and B1-B11 are concentric arcs with center H. ∠A1HA11≠∠B1HB11, which creates a stroke difference between the extending connecting rod 1 and the rotating connecting rod 2. This causes the rack segment of the rotating connecting rod 2 to mesh with the rotating gear, causing the rotating gear to rotate and thus driving the air guide plate to flip.

[0108] During the process of the drive mechanism driving the air guide plate, the rotating gear of the air guide plate and the rack segment of the rotating connecting rod 2 need to be tangent at all times. Therefore, when the extended connecting rod 1 moves with the rotating connecting rod 2, the speed along the normal direction of the meshing point of the rotating gear and the rack segment needs to be equal at all times. Different speeds in the tangential direction can cause a stroke difference, thereby causing the air guide plate to rotate.

[0109] The multiple arc segments provided in this embodiment are designed as concentric arc tracks, which have simple and regular paths and are conducive to improving the driving accuracy and stability of the drive mechanism in controlling the rotation angle of the air guide plate.

[0110] Optionally, the drive mechanism includes a drive element 3.

[0111] Driven element 3 rotates under the drive of the motor.

[0112] The driving element 3 includes a first driving shaft 31 for driving the extension link 1 and a second driving shaft 32 for driving the rotation link 2. The driving element 3 has a driving rotation center 33, and the driving rotation center 33, the first driving shaft 31 and the second driving shaft 32 are located on the same straight line.

[0113] In this embodiment, the first drive shaft 31 that drives the extension link 1 and the second drive shaft 32 that drives the rotating link 2 are located on the same straight line as the drive rotation center 33 of the drive element 3. This simplifies the path rules between the drive mechanism and the rotation of the air guide plate.

[0114] Optionally, the drive mechanism also includes a motor gear 34.

[0115] The motor gear 34 is directly driven by the motor. The drive element 3 is provided with a drive rack 301, which meshes with the motor gear 34 to drive the drive element 3 to rotate.

[0116] Optionally, the motor gear 34 is provided with circumferential teeth, and a drive rack 301 is provided on a portion of the outer circumferential surface of the drive element 3. The drive rack 301 is an arc-shaped rack. The radius of the motor gear 34 is smaller than the radius of the drive rack 301. The rotation of the motor gear 34 drives the rotation of the drive element 3, which in turn causes the drive element 3 to drive the extension connecting rod 1 and the rotating connecting rod 2 to move. In this embodiment, the motor gear 34 increases the torque of the drive element 3.

[0117] Optionally, the driving element 3 includes a first driving end 302 that is far from the driving rotation center 33, wherein the first driving shaft 31 is disposed at the first driving end 302.

[0118] The first driving end 302 is the end of the driving element 3 furthest from the center of rotation 33, and the first driving shaft 31 is disposed at the first driving end 302. This increases the rotation radius R1 of the first driving end 302.

[0119] Optionally, the distance between the first drive shaft 31 and the second drive shaft 32 is QR1, where R2 ≥ 3QR1.

[0120] In this embodiment of the disclosure, the distance QR1 between the first drive shaft 31 and the second drive shaft 32 is relatively small, and the distance R2 between the drive rotation center 33 and the second drive shaft 32 is relatively large.

[0121] In this embodiment, the distance between the first drive shaft 31 and the second drive shaft 32 and the drive rotation center 33 is relatively large, and the overall length of the crank is relatively large. Thus, the crank can drive the air guide plate to open in the first direction and in the second direction even with a relatively small rotation angle.

[0122] Optionally, the connecting member 41 of the air guide plate has a guide plate rotation center 401, the distance between the first track position 123 and the guide plate rotation center 401 is SL5, and the distance between the second track position 223 and the guide plate rotation center 401 is XL3, wherein SL5 > XL3.

[0123] In the initial state where the air guide plate is closed, the distance SL5 between the first track position 123 and the center of rotation 401 of the air guide plate is greater than the distance XL3 between the second track position 223 and the center of rotation 401 of the air guide plate. For example... Figure 24 As shown.

[0124] Optionally, the drive element 3 includes a drive rack 301, which meshes with the motor gear 34 of the motor. The drive rack 301 includes a first end drive tooth 3011 and a second end drive tooth 3012 located at both ends.

[0125] The driving element 3 includes a first driving shaft 31 for driving the extension link 1 and a second driving shaft 32 for driving the rotation link 2. The driving element 3 has a driving rotation center 33. The line connecting the first end driving tooth 3011 and the second end driving tooth 3012 is the first tooth line. The driving rotation center 33, the first driving shaft 31 and the second driving shaft 32 are all located on the same side of the first tooth line.

[0126] like Figure 25 As shown, a drive rack 301 is provided on a portion of the side of the drive element 3. A first tooth connection line is obtained by virtually connecting the first end drive teeth 3011 and the second end drive teeth 3012 located at both ends of the drive rack 301. The drive rotation center 33, the first drive shaft 31, and the second drive shaft 32 are all located on the same side of the first tooth connection line. The first tooth connection line includes a first connection line side facing the guide plate rotation center 401 and a second connection line side away from the guide plate rotation center 401, wherein the drive rotation center 33, the first drive shaft 31, and the second drive shaft 32 are all located on the first connection line side of the first tooth connection line. This embodiment of the present disclosure provides the design positions of the drive rack 301 of the drive element 3 with the drive rotation center 33, the first drive shaft 31, and the second drive shaft 32.

[0127] Optionally, the drive rack 301 is an arc-shaped rack, wherein the drive rotation center 33 is located on the concave side of the arc-shaped rack.

[0128] like Figure 25 As shown, the drive rack 301 is an arc-shaped rack, and the center 33 of the drive rotation of the first drive shaft 31 and the second drive shaft 32 is located on the concave side of the arc-shaped rack. Optionally, the center 33 of the drive rotation is the center of the circle containing the arc-shaped rack. In this way, the rotation trajectory of the drive element 3 is a standard circle, and the motion trajectories of the extended connecting rod 1 and the rotating connecting rod 2 can be matched with the circular motion of the drive element 3, reducing the motion conversion error between the motion of the drive element 3 and the two connecting rods, and simplifying the calculation law of the conversion between their motions.

[0129] Optionally, the line connecting the driving rotation center 33 and the first end driving tooth 3011 is the second tooth line, and the line connecting the driving rotation center 33 and the second end driving tooth 3012 is the third tooth line. The included angle between the second tooth line and the third tooth line is e1, where 80°≤e1≤125°.

[0130] like Figure 26 As shown, the included angle e1 between the second tooth connection line and the third tooth connection line can be 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, or 125°. In this embodiment, the drive rack 301 only needs to be designed with a small circumferential segment, smaller than a semicircle, to achieve the drive of the extending connecting rod 1 and the rotating connecting rod 2.

[0131] Optionally, the distance between the first drive shaft 31 and the second drive shaft 32 is QR1, the distance between the second drive shaft 32 and the drive rotation center 33 is R2, and the radius of the circle in which the drive rack 301 is located is r, where R2 > r.

[0132] In this embodiment of the present disclosure, the distance between the first drive shaft 31 and the second drive shaft 32 and the center of the drive rotation circle 33 is larger than the radius r of the circle in which the drive rack 301 is located. This allows the drive element 3 to drive the extended connecting rod 1 with only one first drive shaft 31 and drive the rotating connecting rod 2 with only one second drive shaft 32.

[0133] Optionally, the drive element 3 includes a crank.

[0134] Optionally, the straight line containing the center of rotation 33, the first drive shaft 31, and the second drive shaft 32 is the first shaft connection line, wherein the angle between the first shaft connection line and the first tooth connection line is e2, and e2≤60°.

[0135] like Figure 25 As shown, the included angle e2 between the first shaft line and the first tooth line is ≤ 60°. For example, e2 can be 60°, 55°, 50°, 45°, 40°, 35°, 30°, or 25°, etc. Optionally, the intersection point of the first shaft line and the first tooth line is located outside the drive element 3.

[0136] Optionally, the driving element 3 has a driving rotation center 33. When the air guide plate rotates from the closed state to open in the first direction, and then rotates from the first direction to open in the second direction, the rotation angle of the driving rotation center 33 is f, and f < 180°.

[0137] The driving element 3 rotates in the same direction, driving the air guide plate from a closed state to an open state in the first direction. The driving element 3 continues to rotate in this direction, driving the air guide plate from an open state in the first direction to an open state in the second direction. Throughout the entire driving process in both directions, the rotation angle f of the driving rotation center 33 of the driving element 3 is less than 180°. Thus, with a relatively large distance between the first driving shaft 31, the second driving shaft 32, and the driving rotation center 33, i.e., with a relatively large overall size of the driving element 3, continuous driving of the air guide plate in both directions can be achieved with a relatively small rotation angle f. Figure 27 As shown. Wherein, the driving rotation center 33 is... Figure 27 Chinese F1.

[0138] Optionally, f < 130°. For example, f can be 125°, 123°, 120°, 117°, 115°, 113°, or 110°. Optionally, f > 90°.

[0139] Optionally, when the air guide plate is in the closed state, the straight line where the drive rotation center 33, the first drive shaft 31 and the second drive shaft 32 are located is the first axis line, wherein the angle f3 between the first axis line and the vertical direction is less than or equal to 15°.

[0140] like Figure 23 As shown, the angle f3 between the first axis line and the vertical direction is relatively small, so that when the air guide plate is in the initial closed state, the first axis line is approximately vertical. Optionally, f3 can be 15°, 12°, 10°, 8°, 7°, 5°, 3°, 2° or 1°, etc.

[0141] Optionally, when the air guide plate rotates from the closed state to the maximum opening angle in the first direction, the rotation angle of the driving rotation center 33 is f1, and when the air guide plate rotates from the maximum opening angle in the first direction to the maximum opening angle in the second direction, the rotation angle of the driving rotation center 33 is f2, where f2≤f1.

[0142] The maximum opening angle of the air guide vane in the first direction can be the maximum upward opening angle in cooling mode, such as... Figure 37 and Figure 40 The position of the middle air guide plate is shown in Figure 3.

[0143] The maximum opening angle of the air guide plate in the second direction can be the maximum downward opening angle in heating mode, such as... Figure 39 and Figure 40 The position of the middle air guide plate is shown in Figure 5.

[0144] like Figure 28 As shown, when the air guide plate rotates from the closed state to the maximum opening angle in the first direction, the first drive shaft 31 of the drive element 3 rotates from position A1 to position A11, the second drive shaft 32 of the drive element 3 rotates from position B1 to position B11, and the rotation angle of the drive rotation center 33 is f1.

[0145] When the air guide plate rotates from the maximum opening angle in the first direction to the maximum opening angle in the second direction, the first drive shaft 31 of the drive element 3 rotates from position A11 to position A111, the second drive shaft 32 of the drive element 3 rotates from position B11 to position B111, and the rotation angle of the drive rotation center 33 is f2.

[0146] In this embodiment of the disclosure, f2 ≤ f1. Optionally, f1 can be 55°, 57°, 60°, 65°, 67°, 70° or 75°, etc.; f2 can be 40°, 42°, 45°, 47°, 49°, 50°, 52° or 55°, etc.

[0147] When miniaturizing the air guide plate drive mechanism, if the distance between the first drive shaft 31, the second drive shaft 32 of the crank and the drive rotation center 33 is large, then the length of the entire crank is longer, and the crank rotation angle f can extend the connecting rod 1 and the rotating connecting rod 2 a longer distance even when the angle f of the crank is relatively small.

[0148] When the overall length of the crank is relatively long, the force of the crank is relatively reduced. Based on this, the drive mechanism provided in this embodiment of the present disclosure is provided with a motor gear 34 to increase the torque.

[0149] Optionally, the connecting member 41 of the air guide plate has a guide plate rotation center 401, the distance between the driving rotation center 33 and the guide plate rotation center 401 is QR2, and the distance between the first driving shaft 31 and the driving rotation center 33 is R1, wherein QR2 > R1.

[0150] In this embodiment of the disclosure, the distance QR2 between the driving rotation center 33 and the guide plate rotation center 401 is slightly larger than the distance R1 between the first driving shaft 31 and the driving rotation center 33. Figure 29 As shown.

[0151] Optionally, the difference between QR2 and R1 is QRx, where QRx < QR1.

[0152] In this embodiment, the difference QRx between QR2 and R1 is relatively small, less than the distance QR1 between the first drive shaft 31 and the second drive shaft 32. This makes the overall drive mechanism smaller and reduces the space occupied by the drive mechanism in the indoor unit of the air conditioner.

[0153] Optionally, the extension link 1 is provided with an extension rod track 12, and the driving element 3 includes a first driving shaft 31 that slides along the extension rod track 12. When the air guide plate opens in the first direction and the second direction, the first driving shaft 31 slides along the extension rod track 12. The rotating link 2 is provided with a rotating rod track 22, and the driving element 3 includes a second driving shaft 32 that slides along the rotating rod track 22. When the air guide plate opens in the first direction and the second direction, the second driving shaft 32 slides along the rotating rod track 22. When the air guide plate is in the closed state, the distance between the extension rod track 12 and the rotating rod track 22 is the track spacing X, and the track spacing X at least partially decreases first and then gradually increases.

[0154] like Figure 30As shown, when the air guide plate is in the closed state, the first track groove line of the extension rod track 12 and the second track groove line of the rotating rod track 22 are drawn. The distance between the extension rod track 12 and the rotating rod track 22 is the distance between the first track groove line and the second track groove line.

[0155] The track spacing X between the two tracks initially decreases gradually, then gradually increases, so that the two tracks roughly form an elongated shape, such as... Figure 30 As shown.

[0156] Optionally, the extension rod track 12 and the rotating rod track 22 intersect at the track intersection point P, wherein the track spacing X at least partially decreases first, and then gradually increases again after reaching the track intersection point P.

[0157] It is understandable that in the actual drive mechanism, the extender rod track 12 and the rotating rod track 22 do not actually intersect. The intersection of the extender rod track 12 and the rotating rod track 22 at point P can be understood as the intersection of the first track groove line and the second track groove line at point P. For example... Figure 30 As shown, along Figure 30 In the direction indicated by the middle arrow, the track spacing X gradually decreases at least partially first, and then gradually increases again after reaching the track intersection point P.

[0158] Optionally, the extendable rod track 12 includes a first track end 121 and a second track end 122 located at both ends, and the rotating rod track 22 includes a third track end 221 and a fourth track end 222 located at both ends.
