Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a driving mechanism, an air deflector assembly and an air conditioner. Background Art

[0002] In existing floor-standing cabinet air conditioners, an open air outlet is often adopted. An upper and lower motor drives upper and lower moving parts to drive a large door panel to open / close, and then a single upper motor at the upper end of an air outlet frame drives a wind guiding connecting rod to drive an air deflector to swing left and right for air sweeping.

[0003] The applicant of the present invention has found that the prior art has at least the following technical problems: in the existing air deflector driving mechanism, a motor drives a motor crankshaft to rotate, the motor crankshaft drives the wind guiding connecting rod to swing, and then the wind guiding connecting rod drives five crankshafts fixedly assembled with the air deflector to swing simultaneously. The five air deflectors will also swing left and right synchronously to realize the left and right air sweeping function. However, through ANSYS dynamic simulation, due to the excessive resistance of driving 5 air deflectors and the insufficient strength of the wind guiding connecting rod (the strength needs to be enhanced, the weight will also increase accordingly, and the driving resistance will also increase), the wind guiding connecting rod is relatively prone to twist and deform. If the strength of the connecting rod is further enhanced, the resistance (motor driving force) will also be very large. Due to the limitation of the dead point position of such a connecting rod mechanism (that is, the driving force direction and the rotation radius direction are close to being on the same straight line), the swinging angle is also limited, and wide-angle air sweeping cannot be realized. In addition, since this connecting rod transmission drives the air deflector to start swinging from the uppermost end, when the air deflector is too long and has an S-shaped deformation, the air deflector will not strictly perform a circular rotation motion around the rotating shaft, and the air deflector is relatively prone to crosstalk. Summary of the Utility Model

[0004] The purpose of the present invention is to provide a driving mechanism, an air deflector assembly and an air conditioner to solve the technical problems in the prior art that the driving mechanism is prone to twist and deform and cannot achieve large-angle air sweeping.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A driving mechanism provided by the present invention includes:

[0007] A rocker arm, which is movably connected to a part to be driven to pull the part to be driven to swing around an axis;

[0008] A driving assembly, which is a dead-point-free driving structure and is in transmission connection with the rocker arm to drive the rocker arm to reciprocate.

[0009] The driving mechanism of the utility model comprises a rocker arm and a driving assembly. The rocker arm is connected to a part to be driven. The driving assembly drives the rocker arm to move. During the movement, the rocker arm can make the part to be driven rotate around an axis. Since the driving assembly is a driving structure without dead points, wide-angle swing can be achieved, the swing angle range is increased, and wide-angle swing is achieved.

[0010] As a further improvement of the present invention, at least one rotating part is provided on the rocker arm, and the driven member can be caused to rotate relative to the rocker arm while being pulled by the rotating part.

[0011] As a further improvement of the present invention, the rotating part includes an eagle's beak with an opening.

[0015] The motor is in transmission connection with the first rotating shaft, and the first rotating shaft is fixedly connected with the rotating chain;

[0016] After the rocker arm slides through the large bracket, it is fixedly connected to the small bracket.

[0017] As a further improvement of the present invention, the first rotating shaft and / or the second rotating shaft are both fixed at an eccentric position of the rotating chain.

[0018] As a further improvement of the present invention, when the first rotating shaft and the second rotating shaft are both eccentrically arranged, the distances between the two and the geometric center of the rotating chain are the same or different.

[0019] As a further improvement of the present invention, the rotating chain is an eight-shaped structure.

[0022] As a further improvement of the utility model, an avoidance gap is provided in the middle position of each of the air guide plate bodies, and a rotating shaft is provided in the avoidance gap; and the rocker arm is connected to all the rotating shafts.

[0023] The air deflector assembly provided by the present utility model drives the air deflector body to swing through a driving mechanism without dead angles, realizing wide-angle air guiding and increasing the air sweeping angle range. Moreover, the driving mechanism in the present utility model has a simple structure and is arranged in the middle of the air deflector body, which not only avoids the problem that the air deflector is prone to deformation and displacement, but also avoids the problem of waste caused by insufficient strength, additional increase in the weight of parts, and increase in material costs. Furthermore, it also avoids the problem of increasing weight to improve the strength of parts, resulting in too large a driving torque of the motor and affecting the service life of the motor.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0037] Embodiment 1:

[0038] In order to improve the wind sweeping swing mechanism, the driving resistance is reduced and the dead point position is avoided, which causes the wide-angle wind sweeping function to be unable to be realized. The utility model proposes a driving mechanism that can realize the wide-angle wind guide to the left and right, and replaces the existing connecting rod transmission in a form similar to gear rotation with the dead-point-free driving structure in the utility model, so as to realize the wide-angle wind sweeping and avoid the dead point position, and at the same time, the problem of excessive motor driving torque and shortening the service life of the motor will not be caused by increasing the weight of materials or parts due to insufficient strength.

[0039] like Figures 6 - 7 As shown, specifically in this embodiment, the driving mechanism includes:

[0040] The rocker arm 1 is movably connected to the driven member to pull the driven member to swing around the axis;

[0041] The driving assembly 2 is a dead-point-free driving structure, which is transmission-connected to the rocker arm 1 and can drive the rocker arm 1 to reciprocate.

[0042] It should be noted here that since there are many embodiments of the driven part, any part that needs to be driven to perform reciprocating motion can be used. For the convenience of explanation, this embodiment takes the driven part as the air guide plate body 10 as an example for specific explanation. Of course, the driving mechanism can also be applicable when the driven part is other parts. Therefore, the solution of combining the driving mechanism with the air guide plate assembly 300 for control in this embodiment is only an embodiment that is easy to understand. The scope of application of the driving mechanism of the utility model is not limited to the air guide plate body 10. In order to simplify the space, the utility model does not go into too much detail about other embodiments.

[0043] It should be noted that the dead point position refers to the angle formed by the direction of the transmitted force and the direction of the rotation radius. When the transmission angle α is 0 degrees, it is the dead point position, and at this time, the transmission efficiency is the lowest.

[0044] The driving mechanism of the present utility model includes a rocker arm 1 and a driving component 2. The rocker arm 1 is connected to the component to be driven, and the driving component 2 drives the rocker arm 1 to move. During the movement of the rocker arm 1, the component to be driven can be rotated around the axis. Since the driving component 2 is a driving structure without dead points, it can achieve wide-angle swing, increase the swing angle range, and realize wide-angle rocking.

[0045] Furthermore, since the air deflector assembly is used for guiding the air direction of the air outlet 100, the number of the air deflector bodies 10 is several, and they are uniformly arranged along the width direction of the air outlet 100. By changing the rotation direction of the air deflector bodies 10, the adjustment of the air outlet direction can be realized. In order to simplify the structure of the driving mechanism, the rocker arm 1 needs to be connected to all the air deflector bodies 10 simultaneously to perform synchronous swing, that is, the rocker arm 1 needs to be able to control all the air deflector bodies 10 to perform synchronous linkage. In this embodiment, at least one rotating part is provided on the rocker arm 1. Optimally, the number of the rotating parts is the same as the number of the air deflector bodies 10. Each rotating part corresponds to one air deflector body 10. During use, the air deflector body 10 can be rotated relative to the rocker arm 1 while being pulled by the rotating part.

[0046] In order to facilitate disassembly and processing, in this embodiment, the rotating part includes an eagle beak 11 with an opening.

[0047] As Figure 6 shown, specifically, the mouth of the eagle beak 11 has a guiding inclined surface, which is convenient for the installation of the air deflector body 10. In order to prevent the air deflector body 10 from disengaging from the eagle beak 11, the width of the mouth of the eagle beak 11 should be smaller than its inner diameter. During installation, the air deflector body 10 can be snapped into the eagle beak 11 by pressing the air deflector body 10 forcefully, so as to realize the rotatable connection between the two.

[0048] In order to achieve smooth rotation, the inner diameter of the eagle beak 11 should be slightly larger than the rotation shaft 40 of the air deflector body 10, that is, there is a clearance fit between the rotation shaft 40 and the inner cavity of the eagle beak 11.

[0049] By adopting a driving mechanism with a new structural form, the present utility model can achieve wide-angle air sweeping, increase the air sweeping angle range, solve the problem of limited existing air sweeping angle, and avoid dead point positions.

[0050] Embodiment 2:

[0051] The difference between this Embodiment 2 and Embodiment 1 is only that in this embodiment, the structure of the driving component 2 is specifically defined.

[0052] As Figures 2 - 7 shown, in this embodiment, the driving assembly 2 includes a motor 21, a rotating linkage 22, a large bracket 23, and a small bracket 24; among which:

[0053] The small bracket 24 is rotatably connected to a ring of the rotating linkage 22 through a first rotating shaft 25;

[0054] The large bracket 23 is sleeved outside the small bracket 24, and the two are arranged one inside the other. The large bracket 23 is rotatably connected to another ring of the rotating linkage 22 through a second rotating shaft 26; further, the small bracket 24 is rotatably connected to the ring of the rotating linkage 22 close to the small bracket 24, while the large bracket 23 is located outside the small bracket 24 and is on the ring of the rotating linkage 22 away from the small bracket 24.

[0055] The motor 21 is drivingly connected to the first rotating shaft 25, and the first rotating shaft 25 is fixedly connected to the rotating linkage 22;

[0056] After the rocker arm 1 slides through the large bracket 23, it is fixedly connected to the small bracket 24.

[0057] The motor 21 serves as a power source and can be used to control the rotation of the first rotating shaft 25. Since the rotating linkage 22 is fixedly connected to the first rotating shaft 25, when the first rotating shaft 25 rotates, it can drive the rotating linkage 22 to rotate. When the rotating linkage 22 rotates, because the large bracket 23 and the first rotating shaft 25 are rotatably connected, that is, they can be connected through a bearing, and the small bracket 24 and the rotating linkage 22 are rotatably connected, that is, the second rotating shaft 26 is fixedly connected to the rotating linkage 22, and the second rotating shaft 26 and the small bracket 24 can be connected through a bearing; also because the rocker arm 1 passes through the large bracket 23 and the small bracket 24 in sequence, and the rocker arm 1 and the large bracket 23 are in a sliding connection relationship, that is, the rocker arm 1 can move relative to the large bracket 23, and the rocker arm 1 and the small bracket 24 are in a fixed connection relationship, so a limiting type of movable connection relationship is formed between the small bracket 24 and the large bracket 23 through the rocker arm 1; when the rotating linkage 22 swings driven by the motor 21, the large bracket 23 will not move under the control of the limiting structure and the rotational connection relationship with the first rotating shaft 25; but the small bracket 24 will move under the swing drive of the rotating linkage 22. This movement includes positions in the horizontal and vertical directions, and the final movement path is an irregular shape. During the movement of the small bracket 24, it will drive the rocker arm 1 to extend or retract relative to the large bracket 23, thereby driving the rocker arm 1 to perform a reciprocating motion.

[0058] When the rocker arm 1 reciprocates, it drives the air deflector assembly 300 connected thereto to swing around the axis;

[0059] It should be noted here that in order to achieve the smooth reciprocating movement of the rocker arm 1 and the swing of the small bracket 24, in the actual design, it is necessary to consider the interval between the large and small brackets, as well as the through structure when the rocker arm 1 passes through the large bracket 23. It is necessary to ensure that the rocker arm 1 can be limited while still moving smoothly. Moreover, the connection between the rocker arm 1 and the small bracket 24 should also be considered as a non-rigid fixed connection to ensure that the small bracket 24 will not be stuck by the connection structure of the rocker arm 1 during swinging and thus cannot swing. The optimal way is that the rocker arm 1 and the small bracket 24 are in a rotatable connection relationship.

[0060] Embodiment 3:

[0061] In order to achieve a larger swing angle and a larger moving stroke of the rocker arm 1, in this embodiment, the connection positions of the first rotating shaft 25, the second rotating shaft 26 and the rotating link 22 are specifically defined.

[0062] As Figures 2 - 7 shown, in this embodiment, the first rotating shaft 25 can be arranged at an eccentric position of the rotating link 22, so that when the rotating link 22 swings, the swing stroke of the small bracket 24 increases, and the swing angle range of the air deflector body 10 is improved;

[0063] Of course, the first rotating shaft 25 can also be arranged at the central position of the rotating link 22, and the second rotating shaft 26 can be arranged at an eccentric position of the rotating link 22. Through this structure, the swing stroke of the small bracket 24 can also be increased, and the swing angle range of the air deflector body 10 is improved.

[0064] Of course, the optimal embodiment is that the first rotating shaft 25 is arranged at an eccentric position of the rotating link 22, and the second rotating shaft 26 is arranged at an eccentric position of the rotating link 22; by arranging both rotating shafts at eccentric positions, the swing stroke of the small bracket 24 is maximally increased, and the swing angle range of the air deflector body 10 is maximized.

[0065] It should also be noted here that when both the first rotating shaft 25 and the second rotating shaft 26 are eccentrically arranged, the distance from the first rotating shaft 25 to the geometric center of the rotating link and the distance from the second rotating shaft 26 to the geometric center of the rotating link can be the same or different, and can be selected according to the actual situation. However, the eccentric directions of the two should be kept consistent.

[0066] In order to reduce the volume of the driving mechanism, in this embodiment, the rotating linkage 22 has an eight-shaped structure and consists of two rings. Since the swinging part of the rotating linkage 22 is mainly the ring connected to the small bracket 24, the two rings of the rotating linkage 22 can have different sizes, and the size of the ring connected to the small bracket 24 is set smaller than that of the ring connected to the large bracket 23. Of course, the two rings can also have the same size. There should be enough space between the lower ring of the rotating linkage 22 and the small bracket 24 so that when both the small bracket 24 and the rotating linkage 22 move, rotational interference will not occur due to their too-close distance.

[0067] In this embodiment, both the large bracket 23 and the small bracket 24 have a U-shaped structure, including a cantilever and a bottom beam. The cantilever part is used for rotatably connecting to the first rotating shaft 25 and the second rotating shaft 26. And the bottom beam part is used for the passing through and connection of the rocker arm 1.

[0068] Embodiment 4:

[0069] In this embodiment, as Figures 2 - 5 shown, the present utility model provides a wind deflector assembly, which includes a plurality of wind deflector bodies 10 arranged side by side and a driving mechanism 20 connected to all the wind deflector bodies 10.

[0070] The top and bottom of the wind deflector body 10 are respectively fixed in the air outlet frame 200 in a limit-type rotational connection manner.

[0071] Specifically, the driving mechanism 20 includes a rocker arm 1 and a driving component 2. The rocker arm 1 is connected to the wind deflector body 10, and the driving component 2 drives the rocker arm 1 to move. During the movement of the rocker arm 1, the wind deflector body 10 can be rotated around an axis; since the driving component 2 is a driving structure without dead points, it can realize large-angle swinging of the wind deflector body 10, increase the swinging angle range, and achieve wide-angle swinging.

[0072] In order to simplify the structure of the driving mechanism 20, the rocker arm 1 needs to be connected to all the wind deflector bodies 10 simultaneously to perform synchronous swinging, that is, the rocker arm 1 needs to be able to control all the wind deflector bodies 10 to perform synchronous linkage. In this embodiment, at least one rotating part is provided on the rocker arm 1. Optimally, the number of rotating parts is the same as the number of wind deflector bodies 10. Each rotating part corresponds to a wind deflector body 10. When in use, the wind deflector body 10 can be rotated relative to the rocker arm 1 while being pulled through the rotating part.

[0073] In order to facilitate disassembly and processing, in this embodiment, the rotating part includes a hawk's beak 11 with an opening.

[0074] Specifically, the mouth of the eagle's beak 11 has a guiding inclined plane, which facilitates the installation of the air deflector body 10. To prevent the air deflector body 10 from disengaging from the eagle's beak 11, the width of the mouth of the eagle's beak 11 should be smaller than its inner diameter. During installation, the air deflector body 10 can be snapped into the eagle's beak 11 by pressing hard on the air deflector body 10, thereby realizing the rotatable connection between the two.

[0075] To achieve smooth rotation, the inner diameter of the eagle's beak 11 should be slightly larger than the rotation axis 40 of the air deflector body 10, that is, there is a clearance fit between the rotation axis 40 and the inner cavity of the eagle's beak 11.

[0076] In this embodiment, the drive assembly 2 includes a motor 21, a rotating chain 22, a large bracket 23, and a small bracket 24; wherein:

[0077] The small bracket 24 is rotatably connected to a ring of the rotating chain 22 through a first rotating shaft 25;

[0078] The large bracket 23 is sleeved outside the small bracket 24, and the two are arranged one inside the other. The large bracket 23 is rotatably connected to another ring of the rotating chain 22 through a second rotating shaft 26; furthermore, the small bracket 24 is rotatably connected to the ring of the rotating chain 22 close to the small bracket 24, while the large bracket 23 is located outside the small bracket 24 and is connected to the ring of the rotating chain 22 on the side away from the small bracket 24.

[0079] The motor 21 is in transmission connection with the first rotating shaft 25, and the first rotating shaft 25 is fixedly connected to the rotating chain 22;

[0080] After the rocker arm 1 slides through the large bracket 23, it is fixedly connected to the small bracket 24.

[0081] The motor 21 serves as a power source and can be used to control the rotation of the first rotating shaft 25. Since the rotating link 22 is fixedly connected to the first rotating shaft 25, when the first rotating shaft 25 rotates, it can drive the rotating link 22 to rotate. When the rotating link 22 rotates, since the large bracket 23 and the first rotating shaft 25 are rotatably connected, that is, they can be connected by a bearing, and the small bracket 24 and the rotating link 22 are rotatably connected, that is, the second rotating shaft 26 and the rotating link 22 are fixedly connected, and the second rotating shaft 26 and the small bracket 24 can be connected by a bearing; also, since the rocker arm 1 passes through the large bracket 23 and the small bracket 24 in sequence, and the rocker arm 1 and the large bracket 23 are in a sliding connection relationship, that is, the rocker arm 1 can move relative to the large bracket 23, and the rocker arm 1 and the small bracket 24 are in a fixed connection relationship, so a limiting type of movable connection relationship is formed between the small bracket 24 and the large bracket 23 through the rocker arm 1; when the rotating link 22 swings driven by the motor 21, the large bracket 23 will not move under the control of the limiting structure and the rotational connection relationship with the first rotating shaft 25; however, the small bracket 24 will move under the driving of the swing of the rotating link 22, and this movement includes the positions in the horizontal and vertical directions, and the final movement path is an irregular shape. During the movement of the small bracket 24, it will drive the rocker arm 1 to extend or retract relative to the large bracket 23, thereby driving the rocker arm 1 to perform a reciprocating motion.

[0082] When the rocker arm 1 reciprocates, it drives the air deflector assembly 300 connected thereto to swing around the axis;

[0083] It should be noted here that in order to achieve the smooth reciprocating movement of the rocker arm 1 and the swing of the small bracket 24, in actual design, it is necessary to consider the interval size between the large and small brackets, as well as the penetration structure when the rocker arm 1 passes through the large bracket 23. It is necessary to ensure that the rocker arm 1 can be limited while still moving smoothly, and the connection between the rocker arm 1 and the small bracket 24 also needs to be considered as a non-rigid fixed connection to ensure that the small bracket 24 will not be stuck by the connection structure of the rocker arm 1 during the swing and cannot swing. The optimal way is that the rocker arm 1 and the small bracket 24 are in a rotatable connection relationship.

[0084] In this embodiment, the first rotating shaft 25 can be arranged at an eccentric position of the rotating link 22, so that when the rotating link 22 swings, the swing stroke of the small bracket 24 increases, and the swing angle range of the air deflector body 10 is increased;

[0085] Of course, the first rotating shaft 25 can also be arranged at the central position of the rotating link 22, and the second rotating shaft 26 can be arranged at an eccentric position of the rotating link 22. Through this structure, the swing stroke of the small bracket 24 can also be increased, and the swing angle range of the air deflector body 10 is increased.

[0086] Of course, in the optimal embodiment, the first rotating shaft 25 is arranged at an eccentric position of the rotating link 22, and the second rotating shaft 26 is arranged at an eccentric position of the rotating link 22; By arranging both rotating shafts at eccentric positions, the swing stroke of the small bracket 24 is maximally increased, and the swing angle range of the air deflector body 10 is maximized.

[0087] It should also be noted here that when both the first rotating shaft 25 and the second rotating shaft 26 are eccentrically arranged, the distance between the first rotating shaft 25 and the geometric center of the rotating link may be the same as or different from the distance between the second rotating shaft 26 and the geometric center of the rotating link, which can be selected according to the actual situation. However, the eccentric directions of the two should be kept consistent.

[0088] In order to reduce the volume of the driving mechanism, in this embodiment, the rotating link 22 is of an eight-shaped structure and consists of two rings. Since the swinging part of the rotating link 22 is mainly the ring connected to the small bracket 24, the two rings of the rotating link 22 can have different sizes, and the specification of the ring connected to the small bracket 24 is set to be smaller than that of the ring connected to the large bracket 23. Of course, the two rings can also have the same specification. There should be enough space between the lower ring of the rotating link 22 and the small bracket 24 so that when both the small bracket 24 and the rotating link 22 move, rotational interference will not occur due to their too close distance.

[0089] In this embodiment, both the large bracket 23 and the small bracket 24 are of U-shaped structures, including cantilevers and bottom beams. The cantilever parts are used for rotatably connecting with the first rotating shaft 25 and the second rotating shaft 26. And the bottom beam parts are used for the passage and connection of the rocker arm 1.

[0090] In order to avoid the problem that the air deflector body 10 is prone to crosstalk, and to avoid the problems of insufficient strength, additional increase in the weight of parts, and waste of material cost, in this embodiment, an avoidance notch 30 is provided at the middle position of each air deflector body, and a rotating shaft 40 is arranged in the avoidance notch; The rocker arm 1 is connected to all the rotating shafts 40.

[0091] The air deflector assembly provided by the present utility model drives the air deflector body to swing through a non-dead-angle driving mechanism, realizing wide-angle air guiding and increasing the sweeping angle range. Moreover, the driving mechanism in the present utility model has a simple structure and is arranged in the middle of the air deflector body, which not only avoids the problem that the air deflector is prone to deformation and crosstalk, but also avoids the problems of insufficient strength, additional increase in the weight of parts or the density weight of parts, and waste of material cost. Further, it also avoids the problem of increasing weight to improve the strength of parts, resulting in too large a driving torque of the motor and affecting the service life of the motor.

[0092] Embodiment 5:

[0093] Such as Figure 1As shown, the air outlet frame of the existing floor-standing open-type air supply cabinet is fixed. The motor fixed at the upper end of the air outlet frame drives the air guiding connecting rod to move, and then the air guiding connecting rod drives the crankshaft and the air guiding plate to swing to achieve the air sweeping function. Since the swing of the connecting rod is restricted by the dead point position, and according to the theory of mechanical principles, the transmission angle needs to be greater than 40° to ensure the best transmission effect. Therefore, the swing angle (air sweeping angle) of the air guiding plate will be greatly restricted, and the air sweeping angle will be very small, such as Figures 2 - 7 As shown, in this embodiment, an air conditioner is provided. The air conditioner includes an air outlet 100, and an air outlet frame 200 is arranged on the air outlet 100. The above-mentioned air guiding plate assembly is arranged in the air outlet frame 200. The air guiding plate assembly is a mechanism that realizes wide-angle air guiding without affecting the transmission efficiency and without adding more parts.

[0094] Furthermore, in this embodiment, the air conditioner is a floor-standing cabinet type. The floor-standing cabinet type can be a square structure. Of course, a round cabinet type can also be adopted.

[0095] In this embodiment, the air guiding plate assembly includes a plurality of air guiding plate bodies 10 arranged side by side and a driving mechanism 20 connected to all the air guiding plate bodies 10.

[0096] The top and bottom of the air guiding plate body 10 are respectively fixed in the air outlet frame 200 in a limit rotation connection manner.

[0097] Specifically, the driving mechanism 20 includes a rocker arm 1 and a driving component 2. The rocker arm 1 is connected to the air guiding plate body 10, and the driving component 2 drives the rocker arm 1 to move. The rocker arm 1 can make the air guiding plate body 10 rotate around the axis during the movement process; since the driving component 2 is a driving structure without dead points, it can realize the large-angle swing of the air guiding plate body 10, increase the swing angle range, and realize wide-angle swinging.

[0098] In order to simplify the structure of the driving mechanism 20, the rocker arm 1 needs to be connected to all the air guiding plate bodies 10 at the same time to swing synchronously, that is, the rocker arm 1 needs to be able to control all the air guiding plate bodies 10 to perform synchronous linkage. In this embodiment, at least one rotating part is arranged on the rocker arm 1. Optimally, the number of rotating parts is the same as the number of air guiding plate bodies 10. Each rotating part corresponds to an air guiding plate body 10. When in use, the air guiding plate body 10 can rotate relative to the rocker arm 1 while being pulled through the rotating part.

[0099] In order to facilitate disassembly and processing, in this embodiment, the rotating part includes an eagle beak 11 with an opening.

[0100] Specifically, the mouth of the eagle's beak 11 has a guiding slope to facilitate the installation of the air deflector body 10. In order to prevent the air deflector body 10 from escaping from the eagle's beak 11, the mouth width of the eagle's beak 11 should be smaller than its inner diameter. During installation, the air deflector body 10 can be inserted into the eagle's beak 11 by pressing the air deflector body 10 hard, thereby achieving a rotatable connection between the two.

[0101] In order to achieve smooth rotation, the inner diameter of the beak 11 should be slightly larger than the rotating shaft 40 of the air guide body 10 , that is, there is a clearance fit between the rotating shaft 40 and the inner cavity of the beak 11 .

[0102] In this embodiment, the driving assembly 2 includes a motor 21, a rotating link 22, a large bracket 23, and a small bracket 24; wherein:

[0103] The small bracket 24 is rotatably connected to a ring of the rotating link 22 via a first rotating shaft 25;

[0104] The large bracket 23 is sleeved on the outside of the small bracket 24, and the two are arranged one inside and one outside. The large bracket 23 is rotatably connected to the other ring of the rotating chain 22 through the second rotating shaft 26; further, the small bracket 24 is rotatably connected to the ring of the rotating chain 22 close to the small bracket 24, and the large bracket 23 is located on the outside of the small bracket 24 and on the ring of the rotating chain 22 away from the small bracket 24.

[0105] The motor 21 is transmission-connected to the first rotating shaft 25, and the first rotating shaft 25 is fixedly connected to the rotating link 22;

[0106] After the rocker arm 1 slides through the large bracket 23 , it is fixedly connected to the small bracket 24 .

[0107] The motor 21 serves as a power source and can be used to control the rotation of the first rotating shaft 25. Since the rotating link 22 is fixedly connected to the first rotating shaft 25, when the first rotating shaft 25 rotates, it can drive the rotating link 22 to rotate. When the rotating link 22 rotates, since the large bracket 23 and the first rotating shaft 25 are rotatably connected, that is, they can be connected through a bearing, and the small bracket 24 and the rotating link 22 are rotatably connected, that is, the second rotating shaft 26 is fixedly connected to the rotating link 22, and the second rotating shaft 26 and the small bracket 24 can be connected through a bearing; also, since the rocker arm 1 passes through the large bracket 23 and the small bracket 24 in sequence, and the rocker arm 1 and the large bracket 23 are in a sliding connection relationship, that is, the rocker arm 1 can move relative to the large bracket 23, and the rocker arm 1 and the small bracket 24 are in a fixed connection relationship, so a limiting type of movable connection relationship is formed between the small bracket 24 and the large bracket 23 through the rocker arm 1; when the rotating link 22 swings driven by the motor 21, the large bracket 23 will not move under the control of the limiting structure and the rotational connection relationship with the first rotating shaft 25; however, the small bracket 24 will move under the driving of the swing of the rotating link 22, and this movement includes the positions in the horizontal and vertical directions, and the final movement path is an irregular shape. During the movement of the small bracket 24, it will drive the rocker arm 1 to extend or retract relative to the large bracket 23, thereby driving the rocker arm 1 to perform a reciprocating motion.

[0108] When the rocker arm 1 reciprocates, it drives the air deflector assembly 300 connected thereto to swing around the axis;

[0109] It should be noted here that in order to achieve the smooth reciprocating movement of the rocker arm 1 and the swing of the small bracket 24, in the actual design, it is necessary to consider the interval size between the large and small brackets, as well as the penetration structure when the rocker arm 1 passes through the large bracket 23. It is necessary to ensure that the rocker arm 1 can be limited while still moving smoothly, and the connection between the rocker arm 1 and the small bracket 24 also needs to be considered as a non-rigid fixed connection to ensure that the small bracket 24 will not be stuck by the connection structure of the rocker arm 1 and cannot swing during the swing of the small bracket 24. The optimal way is that the rocker arm 1 and the small bracket 24 are in a rotatable connection relationship.

[0110] In this embodiment, the first rotating shaft 25 can be arranged at an eccentric position of the rotating link 22, so that when the rotating link 22 swings, the swing stroke of the small bracket 24 increases, and the swing angle range of the air deflector body 10 is increased;

[0111] Of course, the first rotating shaft 25 can also be arranged at the central position of the rotating link 22, and the second rotating shaft 26 can be arranged at an eccentric position of the rotating link 22. Through this structure, the swing stroke of the small bracket 24 can also be increased, and the swing angle range of the air deflector body 10 is increased.

[0112] Of course, in the optimal embodiment, the first rotating shaft 25 is arranged at an eccentric position of the rotating linkage 22, and the second rotating shaft 26 is arranged at an eccentric position of the rotating linkage 22; by arranging both rotating shafts at eccentric positions, the swing stroke of the small bracket 24 is maximally increased, and the swing angle range of the air deflector body 10 is maximized.

[0113] It should also be noted here that when both the first rotating shaft 25 and the second rotating shaft 26 are eccentrically arranged, the distance between the first rotating shaft 25 and the geometric center of the rotating linkage may be the same as or different from the distance between the second rotating shaft 26 and the geometric center of the rotating linkage, which can be set according to the actual situation. However, the eccentric directions of the two should be the same.

[0114] In order to reduce the volume of the driving mechanism, in this embodiment, the rotating linkage 22 has an eight-shaped structure and is composed of two rings. Since the swinging part of the rotating linkage 22 is mainly the ring connected to the small bracket 24, the two rings of the rotating linkage 22 can have different sizes, and the size of the ring connected to the small bracket 24 can be set smaller than the ring connected to the large bracket 23. Of course, the two rings can also have the same specifications. There should be enough space between the lower ring of the rotating linkage 22 and the small bracket 24 to prevent rotational interference due to the two being too close when both the small bracket 24 and the rotating linkage 22 move.

[0115] In this embodiment, both the large bracket 23 and the small bracket 24 have a U-shaped structure, including a cantilever and a bottom beam. The cantilever part is used for rotatably connecting to the first rotating shaft 25 and the second rotating shaft 26. The bottom beam part is used for the rocker arm 1 to pass through and connect.

[0116] In order to avoid the problem that the air deflector body 10 is prone to crosstalk, and to avoid problems such as insufficient strength, additional weight of parts, and waste of material cost, in this embodiment, an avoidance notch 30 is provided at the middle position of each air deflector body, and a rotating shaft 40 is arranged in the avoidance notch; the rocker arm 1 is connected to all the rotating shafts 40. By installing the driving mechanism at the middle position of the air deflector body 10, the driving mechanism drives the rotation of the rotating shaft at the middle position of the air deflector body, which can maximally avoid the crosstalk problem of the air deflector.

[0117] The air conditioner of the present utility model can achieve wide-angle air sweeping and avoid dead points, and at the same time, it will not have problems such as insufficient strength, which will increase the weight of materials or parts, cause excessive motor driving torque, and affect the service life of the motor, and can also avoid the crosstalk problem that the air deflector is prone to.

[0118] Usage method:

[0119] When the air conditioner is operating, the motor 21 drives the first rotating shaft 25 to rotate. The rotating link 22 fixedly assembled with the first rotating shaft 25 will swing back and forth around the first rotating shaft 25 (which belongs to an irregular swing motion. Here, the irregularity means that the shape of the swing route is an irregular shape). At the same time, it also drives the small bracket 24 assembled with the other end of the rotating link 22 by the second rotating shaft 26. Since the second rotating shaft 26 at the lower end of the rotating link 22 can rotate relative to the small bracket 24, and the rocker arm 1 connected to the small bracket 24 is assembled and matched with the limiting hole of the large bracket 23, the small bracket 24 will only move back and forth in the up and down direction (in a straight line). Since the eagles' beaks 11 on the rocker arm 1 of the small bracket 24 are respectively rotationally matched with the rotating shafts 40 on the air deflector body 10, when the rocker arm 1 of the small bracket 24 moves back and forth, it will drive the air deflector body 10 to rotate and swing. The swing angle of the air deflector body 10 depends on the amplitude of the back-and-forth movement of the rocker arm 1, and the amplitude of the back-and-forth movement of the rocker arm 1 depends on the distance between the rotation center and the geometric center on the rotating link 22. The farther the distance, the greater the amplitude of the back-and-forth movement of the rocker arm 1. The essence of the driving mechanism of the present invention is to first convert the rotational motion into a linear motion, and then convert the linear motion into a (rotating motion of the air deflector body). This driving mechanism is not restricted by the transmission angle and dead point of the single-link mechanism. The swing angle of the air deflector is determined by the distance between the rotation center and the geometric center of the rotating link.

[0120] The driving mechanism of the present invention has a simple structure, can achieve wide-angle air sweeping, avoid the dead point position, and at the same time, it will not increase the material or part weight due to insufficient strength, resulting in an excessive driving torque of the motor and affecting the service life of the motor. At the same time, since the air deflector driving mechanism drives the swing of the rotating shaft at the middle position of the air deflector, it also avoids the problem of easy crosstalk of the air deflector.
