Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically providing a drive device for an air guide plate, an indoor air conditioning unit, and an air conditioning system. Background Technology

[0002] Currently, air conditioners are an indispensable appliance in daily work and life. They guide airflow by adjusting the angle of the air guide plate relative to the air outlet of the air conditioner, thereby changing the air outlet mode.

[0003] However, in related technologies, due to factors such as the size of the space around the air outlet of the air conditioner and the structural characteristics of the air guide plate drive device, the air guide plate can usually only rotate around a certain axis within a small angle range, making it difficult to rotate a large range to meet different user needs, thereby reducing the user's user experience.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] This application aims to solve the aforementioned technical problem, namely, to address the issue of reduced user experience due to the limited rotation range of the air guide vane in air conditioners.

[0006] In a first aspect, this application provides a driving device for an air guide vane, comprising:

[0007] chassis;

[0008] The transmission assembly includes a first connecting rod slidably disposed on the housing along a first direction and a second connecting rod disposed side by side with the first connecting rod, both the first connecting rod and the second connecting rod being able to extend out of the housing and be hinged to the air guide plate;

[0009] A first drive assembly, which is connected to the first link, is used to drive the first link and the second link to translate along the first direction;

[0010] The second drive assembly, which is connected to the second link, is used to drive the second link to swing relative to the first link, thereby controlling the rotation of the air guide plate.

[0011] In one technical solution of the above-mentioned driving device, the first driving component includes:

[0012] A rack, which is mounted on the first connecting rod;

[0013] The first driver has a gear connected to its output end, and the gear meshes with the rack.

[0014] In one technical solution of the above-mentioned driving device, a support column is provided on the first connecting rod, and a first sliding groove is provided on the surface of the second connecting rod facing the first connecting rod. The support column is located in the first sliding groove. When the second driving component applies torque to the free end of the second connecting rod, the support column can slide and rotate relative to the first sliding groove, thereby causing the second connecting rod to swing.

[0015] In one technical solution of the above-mentioned driving device, a second groove is formed on the surface of the second connecting rod opposite to the surface of the first connecting rod, and the second driving assembly includes:

[0016] A crank has a first end and a second end opposite to each other. The first end is provided with a drive column, which is located in the second slide groove. During the process of the first drive assembly driving the first connecting rod and the second connecting rod to move along the first direction, the drive column slides relative to the second slide groove.

[0017] The second driver, whose output is connected to the second end of the crank, is used to drive the crank to rotate so as to apply torque to the free end of the second connecting rod.

[0018] In one technical solution of the above-mentioned drive device, the housing includes a first cover and a second cover that are fastened to each other. The first cover has a first side wall, and the second cover has a second side wall. The first side wall and the second side wall are arranged opposite to each other.

[0019] The first connecting rod is slidably mounted on the first side wall;

[0020] The first driver and the second driver are disposed on the second sidewall.

[0021] In one technical solution of the above-mentioned driving device, a guide rail is provided on the surface of the first connecting rod facing the first side wall along the first direction, and a plurality of rollers are rotatably arranged on the first side wall along the first direction, the rollers being located within the guide rail.

[0022] In one technical solution of the above-mentioned drive device, the crank is located outside the housing, and an arc-shaped hole adapted to the rotation trajectory of the drive column is provided on the second side wall. The drive column passes through the arc-shaped hole and extends into the second slide groove.

[0023] In one technical solution of the aforementioned driving device, both ends of the second slide are closed.

[0024] In a second aspect, this application provides an indoor air conditioning unit, comprising:

[0025] The driving device for the air guide plate as described in any one of the first aspects is disposed on the side surface of the indoor unit of the air conditioner;

[0026] An air guide plate is disposed at the air outlet of the indoor unit of the air conditioner, and the air guide plate is connected to the first connecting rod and the second connecting rod respectively.

[0027] In a third aspect, this application provides an air conditioning system that includes the indoor unit described in the second aspect.

[0028] When the above technical solution is adopted, during the operation of the air conditioner, the first drive component first controls the translation of the first link and the second link to control the air guide plate to extend forward. Then, the second drive component controls the second link to swing relative to the first link to control the air guide plate to rotate. In this way, the process of adjusting the posture of the air guide plate is decomposed into two motion processes. When the air guide plate rotates, there is a certain distance between it and the air outlet of the air conditioner. Therefore, the rotation angle range of the air guide plate is wider, which can meet the higher usage needs of users and improve the user experience. Attached Figure Description

[0046] Reference Figure 1This is a schematic diagram of a driving device for a guide vane according to an embodiment of the present application and its assembled state with the guide vane. The driving device is installed at the end of the guide vane 100 to drive the guide vane 100 to move.

[0047] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 2 This is a three-dimensional exploded view of a driving device according to an embodiment of this application. Figure 3 for Figure 2 A diagram from another perspective. Figure 4 This is a schematic diagram showing the air guide plate in its initial position. Figure 5 This is a schematic diagram showing the air guide vane in its initial position from another perspective. The initial position refers to the position of the air guide vane before the air conditioner starts operating, at which point the air guide vane essentially closes the air outlet of the air conditioner.

[0048] The drive unit for the air guide plate includes a housing 1, a transmission assembly 2, a first drive assembly 3, and a second drive assembly 4. The transmission assembly 2, the first drive assembly 3, and the second drive assembly 4 are all mounted on the housing 1, so that the drive unit can be independently mounted on the side surface of the indoor air conditioner unit.

[0049] In one embodiment of this application, the housing 1 includes a first cover 11 and a second cover 12, which are detachably connected and can be fastened together as a whole.

[0050] The transmission assembly 2 includes a first link 21 and a second link 22. The first link 21 is slidably mounted on the housing 1 along a first direction. This first direction can be a direction substantially perpendicular to the cross-section where the air outlet of the indoor unit is located. For example, taking a wall-mounted indoor unit as an example, the first direction is... Figure 4 The direction indicated by the middle arrow means that when the indoor unit of the air conditioner is installed on the wall, the air outlet faces diagonally downwards, so the first direction is the downward tilt.

[0051] In one implementation of this application, the first connecting rod 21 is slidably disposed on the first cover 11. The first cover 11 has a first sidewall 111, and the second cover 12 has a second sidewall 121 opposite to the first sidewall 111. The first connecting rod 21 is slidably disposed on the first sidewall 111. The first connecting rod 21 and the first sidewall 111 can be connected by a guide rail or slider, for example, a guide rail 211 is provided on the surface of the first connecting rod 21 facing the first sidewall 111 along a first direction. Correspondingly, a plurality of rollers 112 are rotatably disposed on the first sidewall 111 along the first direction. The plurality of rollers 112 are all located inside the guide rail 211, and the outer peripheral surface of the rollers 112 is in contact with the inner wall surface of the guide rail 211. In this way, the rolling friction formed between the rollers 112 and the guide rail 211 reduces the friction during the sliding process.

[0052] The first drive assembly 3 is connected to the first connecting rod 21 and is used to drive the first connecting rod 21 to translate along a first direction. Optionally, the first drive assembly 3 includes a rack 31 and a first driver 32. The rack 31 is fixedly mounted on the first connecting rod 21, and the first driver 32 can be a power component such as a servo motor. The output end of the first driver 32 is connected to a gear 33, which meshes with the rack 31, thereby driving the first connecting rod 21 to move. It should be noted that in practical applications, the rack 31 can be a separately machined component that is fixedly connected to the first connecting rod 21, or it can have teeth machined on the first connecting rod 21 to form a continuous rack 31. This is a conventional method in engineering applications, and those skilled in the art can choose according to actual needs.

[0053] The second link 22 is arranged side by side with the first link 21. A support column 212 is fixedly installed at the middle position of the first link 21. The cross-section of the support column 212 is circular. The surface of the second link 22 facing the first link 21 is provided with a first sliding groove 221 that cooperates with the support column 212. The first sliding groove 221 can be an oblong groove. The support column 212 is located in the first sliding groove 221 and can slide along the first sliding groove 221 and rotate relative to the first sliding groove 221 at the same time.

[0054] The second connecting rod 22 has a second groove 222 on its surface opposite to the first connecting rod 21. The cross-sectional shape of the second groove 222 can be the same as that of the first groove 221, that is, both are set as waist-shaped grooves. Based on this, the second drive assembly 4 includes a crank 41 connected to the second groove 222 and a second driver 42 that drives the crank 41 to rotate. Specifically, the crank 41 has a first end 411 and a second end 412 opposite to each other. A drive column 413 is fixedly provided on the first end 411. The cross-section of the drive column 413 is circular, and its diameter is adapted to the width of the second groove 222. The drive column 413 is located in the second groove 222 and can slide and rotate relative to the second groove 222. The second driver 42 can be a power component such as a servo motor. The output end of the second driver 42 is connected to the second end 412, thereby driving the crank 41 to rotate and applying torque to the free end of the second connecting rod 22 to control the swing of the second connecting rod 22. For ease of description, the ends of the first connecting rod 21 and the second connecting rod 22 that are hinged to the air guide plate 100 are called their hinged ends, and the ends opposite to the hinged ends are called the free ends.

[0055] The following combination Figures 4-11 The process of the drive device driving the air guide plate 100 to move is described.

[0056] Reference Figure 4 and Figure 5 In the initial position, the first link 21 and the second link 22 are parallel to each other, and the first slide 221 and the second slide 222 both extend along the first direction. At this time, the drive column 413 on the crank 41 is located at the end of the second slide 222 near the air guide plate 100, and the support column 212 is located at the end of the first slide 221 near the air guide plate 100.

[0057] Reference Figure 6 and Figure 7 , Figure 6 This is a schematic diagram showing the air guide plate in its first position. Figure 7 This is a schematic diagram from another perspective when the air guide plate is in the first position. The first position refers to the position where the air guide plate 100 only extends forward to the top of its stroke without rotating. During the process of the air guide plate 100 moving from the initial position to the first position, only the first drive component 3 works. The first driver 32 drives the gear 33 to rotate, and the gear 33 drives the rack 31, the first connecting rod 21 and the second connecting rod 22 to translate.

[0058] Reference Figure 8 and Figure 9 , Figure 8 This is a schematic diagram showing the air guide plate in the second position. Figure 9This is a schematic diagram from another perspective when the air guide plate is in the second position. The second position refers to the position where the air guide plate 100 is rotated downwards to its limit. At this point, the air guide plate 100 blocks the space below the air conditioner outlet, and the airflow blows upwards. This method is typically used when the air conditioner is in cooling mode, causing the cold air to move upwards and improving the cooling effect. During the movement of the air guide plate 100 from the first position to the second position, the first drive assembly 3 stops working, and the second drive assembly 4 starts working. The second driver 42 applies torque to the crank 41, and the drive column 413 drives the crank 41 to rotate. During this process, the support column 212 rotates relative to the first slide groove 221 and slides slightly within the first slide groove 221. Thus, the second connecting rod 22 swings around the support column 212. During this process, the hinge end of the first connecting rod 21 is fixed, and the hinge end of the second connecting rod 22 moves relative to the hinge end of the first connecting rod 21, thereby realizing the rotation of the air guide plate 100.

[0059] Reference Figure 10 and Figure 11 , Figure 10 This is a schematic diagram showing the air guide plate in the third position. Figure 11 This is a schematic diagram from another perspective when the air guide plate is in the third position. The third position is when the air guide plate 100 is rotated upwards to its limit. At this position, the air guide plate 100 blocks the space above the air conditioner outlet, and the airflow blows downwards. This method is typically used when the air conditioner is in heating mode to make hot air move downwards, improving heating efficiency. During the process of the air guide plate 100 moving from the second position to the third position, the air guide plate 100 first reverses the previous movement (i.e., the process of the air guide plate 100 moving from the first position to the second position) to the first position, and then rotates from the first position to the third position. The actions of each component during the process of the air guide plate 100 rotating from the first position to the third position are as described above. Figure 8 and Figure 9 The process shown is similar, except that the rotation direction of crank 41 is opposite to that described above, so this application will not elaborate on it here.

[0060] As can be seen from the above, by adopting the technical solution of this application, during the operation of the air conditioner, the first drive component 3 first controls the translation of the first link 21 and the second link 22 to control the air guide plate 100 to extend forward. Then, the second drive component 4 controls the second link 22 to swing relative to the first link 21 to control the air guide plate 100 to rotate. In this way, the process of adjusting the posture of the air guide plate 100 is decomposed into two motion processes. When the air guide plate 100 rotates, there is a certain distance between it and the air conditioner outlet. Therefore, the rotation angle range of the air guide plate 100 is wider, which can meet the higher usage needs of users and improve the user experience.

[0061] Reference Figure 2 and Figure 3 In one implementation of this application, based on considerations of spatial layout rationality, both the first driver 32 and the second driver 42 are disposed on the second sidewall 121. Optionally, the crank 41 is located outside the housing 1, and the second sidewall 121 has an arc-shaped hole 1211 adapted to the rotation trajectory of the drive column 413. The drive column 413 passes through the arc-shaped hole 1211 and extends into the second slide groove 222. In this way, the crank 41 is located outside the housing 1 and does not occupy the internal space of the housing 1. There is no need to reserve independent space for the crank 41 inside the housing 1 based on motion interference considerations, thereby reducing the complexity of the internal structure of the housing 1 and making the distribution of various functional components inside the housing 1 more compact.

[0062] In one embodiment, both ends of the second slide groove 222 are closed. In this way, the inner wall of the second slide groove 222 can limit the stroke of the first connecting rod 21 and the second connecting rod 22 during the extension and retraction process, which is beneficial to control the end point of the stroke and can also prevent the drive column 413 from slipping out of the second slide groove 222 due to unexpected situations.

[0063] This application also discloses an indoor air conditioner unit, which includes a driving device for the air guide plate and an air guide plate 100 as described in any of the above embodiments. The driving device for the air guide plate is disposed on the side surface of the indoor air conditioner unit (the side surface refers to the surface where the end of the indoor air conditioner unit is located in the length direction), and the air guide plate 100 is disposed at the air outlet of the indoor air conditioner unit. The air guide plate 100 is hinged to the first connecting rod 21 and the second connecting rod 22 respectively.

[0064] This application also discloses an air conditioning system that includes the indoor unit of the air conditioner in the above embodiments.

[0065] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
