Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically providing a driving device for an air guide plate and an air conditioner. 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. Summary of the Invention

[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] The casing has opposing first and second sidewalls inside;

[0008] A substrate, which is slidably disposed on the first sidewall along a first direction;

[0009] The transmission mechanism includes a first main connecting rod and a second main connecting rod arranged side by side, and a first auxiliary connecting rod and a second auxiliary connecting rod connected between the first main connecting rod and the second main connecting rod. The middle part of the first auxiliary connecting rod and the middle part of the second auxiliary connecting rod are rotatably connected to the base plate. The first main connecting rod and the second main connecting rod can both extend out of the housing and be hinged to the air guide plate.

[0010] A driver for driving the substrate and the transmission mechanism to move along the first direction;

[0011] A guide structure is used to control the synchronous rotation of the first auxiliary link and the second auxiliary link during the movement of the transmission mechanism along the first direction, thereby driving the first main link and the second main link to move relative to each other.

[0012] In one technical solution of the above-mentioned driving device, the guiding structure includes:

[0013] A guide post is mounted on the second auxiliary connecting rod;

[0014] A guide rail is disposed on the second side wall, and the guide post is slidably disposed within the guide rail. The extension trajectory of the guide rail is arranged at an angle to the first direction in the tangential direction at at least a portion of its position, so that the guide post generates a torque on the second auxiliary connecting rod during the sliding process along the guide rail.

[0015] In one technical solution of the above-mentioned driving device, the guide post includes a first guide post and a second guide post, and the line connecting the first guide post and the rotation center of the second auxiliary connecting rod and the line connecting the second guide post and the rotation center of the second auxiliary connecting rod are set at an angle;

[0016] The guide rail includes a first guide rail and a second guide rail disposed on the second side wall. When the first guide post slides in the first guide rail, the first main connecting rod and the second main connecting rod move relative to each other, thereby controlling the air guide plate to rotate within a first angle range. When the second guide post slides in the second guide rail, the first main connecting rod and the second main connecting rod move relative to each other, thereby controlling the air guide plate to rotate within a second angle range.

[0017] In one technical solution of the above-mentioned drive device, the housing has an opening, the first main connecting rod and the second main connecting rod extend out of the housing through the opening, and the second guide rail is closer to the opening than the first guide rail;

[0018] The first guide rail includes a first guide segment and a second guide segment that are continuous with each other. The second guide segment is close to the second guide rail, and the ends of the second guide segment and the second guide rail that are close to each other are both open.

[0019] In one technical solution of the above-mentioned driving device, the trajectory of the second guide segment is an arc, and the first guide segment includes an arc segment symmetrically arranged with the second guide segment and a straight segment connected to the arc segment, the straight segment extending along the first direction.

[0020] In one technical solution of the above-mentioned driving device, the end of the first guide rail away from the opening is closed.

[0021] In one technical solution of the above-mentioned driving device, the end of the second guide rail near the opening is closed.

[0022] In one technical solution of the above-mentioned driving device, the height of the second guide rail is less than the height of the first guide rail in the direction perpendicular to the second sidewall;

[0023] The length of the first guide post is less than the length of the second guide post, so that the first guide post does not interfere with the second guide post during its rotation after it leaves the first guide rail.

[0024] In one technical solution of the above-mentioned driving device, the output end of the driver is connected to a gear, and a rack that cooperates with the gear is provided on the substrate. When the driver drives the gear to rotate, the gear drives the rack and the substrate to move along the first direction.

[0025] In a second aspect, this application provides an air conditioner comprising:

[0026] An indoor unit for an air conditioner, which has an air outlet;

[0027] The driving device for the air guide plate as described in any one of the first aspects is disposed on the indoor unit of the air conditioner;

[0028] The air guide plate is connected to the first main connecting rod and the second main connecting rod respectively. When the driving device is activated, it drives the air guide plate to move through the first main connecting rod and the second main connecting rod to close the air outlet or rotate relative to the air outlet.

[0029] When the above technical solution is adopted, after the air conditioner is started, the driver drives the base plate and the transmission mechanism to translate. At the same time, the guide structure controls the synchronous rotation of the second auxiliary link and the first auxiliary link in the transmission mechanism to control the relative movement of the first main link and the second main link. This causes the air guide plate to extend in a compound motion combining translation and rotation. In this way, during the rotation of the air guide plate, a sufficient gap is formed between its edge 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.

[0030] On the other hand, in this application, the rotation of the air guide plate is achieved by the torque generated by the guide rail on the guide column, which causes the second auxiliary link and the first auxiliary link to rotate passively, thus eliminating the need for additional driving force. That is, this application achieves both translation and rotation of the air guide plate through a single driving element, which simplifies the overall structure of the driving device and reduces costs.

[0048] Reference Figure 1 This is a schematic diagram of a wind deflector driving device according to an embodiment of the present application and its assembled state with the wind deflector. The driving device is installed at the end of the wind deflector 100 to drive the wind deflector 100 to move.

[0049] Reference Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a schematic diagram of the internal structure of a drive device for an air guide plate according to an embodiment of this application. Figure 3 This is a three-dimensional exploded view of a drive device for a guide vane according to an embodiment of this application. Figure 4 yes Figure 3 A diagram from another perspective. Specifically, Figure 2 This is the state when the air guide plate is in its initial position. The initial position refers to the position of the air guide plate before the air conditioner is running. At this time, the air guide plate basically closes the air outlet of the air conditioner.

[0050] The drive device for the air guide plate includes a housing 1, a base plate 2, a transmission mechanism 3, a driver 4, and a guide structure. The housing 1 includes a first cover 11 and a second cover 12, which are detachably connected and can be fastened together to form a space within the housing 1 for accommodating the base plate 2, the transmission mechanism 3, the driver 4, and the guide structure.

[0051] 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 base plate 2 is slidably disposed on the first sidewall 111 along a first direction, wherein the 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 2 As indicated by the middle arrow, when the indoor unit of the air conditioner is installed on the wall, its air outlet faces downwards at an angle; therefore, the first direction is a downward tilt. The substrate 2 and the first sidewall 111 can be connected by a guide rail or slider to achieve reciprocating linear motion of the substrate 2. This is a conventional technique in the field and will not be elaborated upon here.

[0052] The transmission mechanism 3 includes a first main connecting rod 31, a second main connecting rod 32, a first auxiliary connecting rod 33, and a second auxiliary connecting rod 34. The first main connecting rod 31, the second main connecting rod 32, the first auxiliary connecting rod 33, and the second auxiliary connecting rod 34 are connected to each other to form a four-bar linkage that can rotate relative to each other. Specifically, the first main connecting rod 31 and the second main connecting rod 32 are parallel to each other, and the first auxiliary connecting rod 33 and the second auxiliary connecting rod 34 are parallel to each other. The two ends of the first auxiliary connecting rod 33 are hinged to the first main connecting rod 31 and the second main connecting rod 32, respectively, and the two ends of the second auxiliary connecting rod 34 are hinged to the first main connecting rod 31 and the second main connecting rod 32, respectively, thus forming a parallelogram linkage mechanism. During the synchronous rotation of the first auxiliary connecting rod 33 and the second auxiliary connecting rod 34, relative motion also occurs between the first main connecting rod 31 and the second main connecting rod 32. The housing 1 has an opening near the air guide plate 100. The ends of the first main connecting rod 31 and the second main connecting rod 32 extend toward the opening and are hinged to the air guide plate 100.

[0053] The substrate 2 has a first rotating shaft 21 and a second rotating shaft 22 at its two ends. The middle part of the first auxiliary connecting rod 33 is rotatably connected to the substrate 2 via the first rotating shaft 21, and the middle part of the second auxiliary connecting rod 34 is rotatably connected to the substrate 2 via the second rotating shaft 22. Thus, when the substrate 2 translates along the first direction, it can drive the entire transmission mechanism 3 to translate. It should be noted that the "middle part" of the first auxiliary connecting rod 33 and the "middle part" of the second auxiliary connecting rod 34 are not limited to the geometric center in the length direction of the two rods. The "middle part" can be any position between the two ends of the two rods, as long as the first auxiliary connecting rod 33 and the second auxiliary connecting rod 34 can rotate relative to the substrate 2.

[0054] The driver 4 can be a power element that outputs torque, such as a servo motor. A gear 41 is connected to the output end of the driver 4. A rack 23 is fixedly mounted on the base plate 2. During the rotation of the gear 41 driven by the driver 4, the gear 41 drives the rack 23 and the base plate 2 to move linearly. In practical engineering applications, the rack 23 can be a separately machined component fixedly connected to the base plate 2, or it can be formed by machining continuous teeth on the base plate 2. These methods are conventional in engineering applications, and those skilled in the art can choose according to actual needs; they do not constitute a limitation of this application.

[0055] Although in the above example of this application, the reciprocating linear motion of the substrate 2 is achieved between the driver 4 and the substrate 2 through a gear and rack transmission, this does not constitute a limitation of this application. Those skilled in the art may also choose to use sprocket and chain transmission, ball screw, synchronous belt transmission or other means that can achieve linear reciprocating motion as alternatives according to actual needs. Such alternatives should all be within the protection scope of this application.

[0056] A guide structure is disposed between the transmission mechanism 3 and the second sidewall 121. As described above, the base plate 2 can drive the transmission mechanism 3 to translate along the first direction, and the purpose of the guide structure is to control the synchronous rotation of the first auxiliary connecting rod 33 and the second auxiliary connecting rod 34 during the translation of the transmission mechanism 3 along the first direction, thereby driving the first main connecting rod 31 and the second main connecting rod 32 to move relative to each other. Since the ends of the first main connecting rod 31 and the second main connecting rod 32 are hinged to the air guide plate 100, the air guide plate 100 is rotated during the relative movement of the first main connecting rod 31 and the second main connecting rod 32.

[0057] Reference Figure 2 , Figure 3 and Figure 4 In one implementation of this application, the guide structure consists of a guide post disposed on the second auxiliary link 34 and a guide rail disposed on the second side wall 121. The guide post is slidably disposed in the guide rail. Through the cooperation of the guide post and the guide rail, the first auxiliary link 33 and the second auxiliary link 34 are passively rotated during the translation along the first direction, thereby causing the first main link 31 and the second main link 32 to move relative to each other.

[0058] In one embodiment, the present application provides two guide posts, namely a first guide post 51 and a second guide post 52, and correspondingly, two guide rails are also provided, namely a first guide rail 53 and a second guide rail 54.

[0059] The first guide post 51 and the second guide post 52 are both fixedly mounted on the second auxiliary connecting rod 34. Both the first guide post 51 and the second guide post 52 have circular cross-sections. The line connecting the rotation center of the first guide post 51 and the second auxiliary connecting rod 34 (i.e., the axis of the second rotating shaft 22) and the line connecting the second guide post 52 and the rotation center of the second auxiliary connecting rod 34 are angled together. The first guide rail 53 and the second guide rail 54 are both fixedly mounted on the second side wall 121. The first guide post 51 can slide within the first guide rail 53, and the second guide post 52 can slide within the second guide rail 54.

[0060] Reference Figure 5 Along the first direction, the second guide rail 54 is closer to the opening in the housing 1, and the first guide rail 53 includes a first guide segment 531 and a second guide segment 532 that are continuous with each other, wherein the second guide segment 532 is closer to the second guide rail 54 than the first guide segment 531. That is, along the first direction, the housing 1 consists of the first guide segment 531, the second guide segment 532, and the second guide rail 54 from the inside out. The ends of the second guide segment 532 and the second guide rail 54 that are close to each other are both open. Thus, during the rotation of the second auxiliary connecting rod 34, the first guide post 51 first slides along the first guide rail 53. When the first guide post 51 approaches the open end of the first guide rail 53, the second guide post 52 enters from the open end of the second guide rail 54, thereby completing the motion connection.

[0061] The following combination Figures 6-11 The process of the drive device driving the air guide plate 100 to move is described.

[0062] 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. It can be seen that the first position refers to the initial stage of the air guide plate's movement. Specifically, relative to... Figure 2 To put it another way, Figure 6 This is the position after the transmission mechanism 3 and the air guide plate 100 extend forward a short distance. In the initial position, the first guide post 51 is located inside the first guide rail 53, while the second guide post 52 is located outside the second guide rail 54. Figure 2 Position towards Figure 6During the positional movement, the driver 4 drives the base plate 2 and the transmission mechanism 3 to move forward as a whole. At the same time, since the first guide segment 531 extends obliquely upward, that is, the extension trajectory line of the first guide segment 531 has an angle with the first direction in the tangent direction of at least a part of its section, the first guide post 51 also has a motion component in the direction perpendicular to the first direction as it slides along the first guide segment 531. As a result, the inner wall of the first guide segment 531 will generate a torque on the second auxiliary connecting rod 34, causing the second auxiliary connecting rod 34 to rotate while moving along the first direction, thereby driving the first main connecting rod 31 and the second main connecting rod 32 to move relative to each other, so that the air guide plate 100 rotates towards the lower part of the air conditioner outlet.

[0063] As can be seen from the above, the movement of the air guide plate 100 is a composite motion, that is, it rotates simultaneously while extending forward. Thus, the distance between the air guide plate 100 and the air conditioner outlet continuously increases as the air guide plate 100 extends forward, thereby reserving space for the air guide plate 100 to rotate between its edge and the air conditioner outlet. Furthermore, it can be understood that during the above-mentioned movement, the second connecting rod 34 is the driving rod, while the first connecting rod 33 acts as the driven rod, providing support. This transmission method is similar to the transmission method of parallelogram linkage mechanisms commonly used in this field, and will not be elaborated further here.

[0064] Reference Figure 5 , Figure 8 and Figure 9 , Figure 8 This is a schematic diagram showing the air guide plate in the second position. Figure 9 This 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, that is, when the air guide plate 100 is rotated downwards to its maximum angle. 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 to make the cold air move upwards, improving the cooling effect. The second guide section 532 is smoothly connected to the first guide section 531. At the connection between the second guide section 532 and the first guide section 531, the air guide plate 100 rotates to the second position. As the first guide post 51 continues to slide along the second guide section 532, the air guide plate 100 begins to rotate in the opposite direction until the air guide plate 100 returns to its initial position.

[0065] In one embodiment of this application, such as Figure 5 As shown, the extension trajectory of the second guide segment 532 is an arc, that is, the second guide segment 532 is an arc-shaped segment as a whole. Correspondingly, the first guide segment 531 also has an arc-shaped segment with the same shape as the second guide segment 532 near the second guide segment 532, and the two are symmetrically distributed. Figure 5The dotted line on the right side is the line of symmetry. The arc segment is designed to make the first guide post 51 smoothly transition at the connection of the two arc segments, making the steering smoother and reducing the jamming phenomenon.

[0066] Optionally, the first guide segment 531 also includes its arc-shaped segment ( Figure 5 A straight segment connecting the section between the left and right dashed lines (in the middle) Figure 5 The section to the left of the dotted line on the left side of the middle section), this straight section extends along the first direction. Thus, in the initial stage of the movement of the first guide post 51, it has no motion component perpendicular to the first direction. At this time, the second connecting rod 34 does not rotate, and the air guide plate 100 only extends forward along the first direction without rotation. With this method, the air guide plate 100 can extend in a straight line in the initial stage of its movement, forming a certain distance between itself and the air conditioner outlet, and then rotate, thereby preventing interference between the air guide plate 100 and the air conditioner outlet, and providing further design space for the size of the air guide plate 100 and the overall size of the air conditioner casing.

[0067] Reference Figure 10 and Figure 11 , Figure 10 This is a schematic diagram showing the air guide plate in the third position. Figure 9 This is a schematic diagram from another perspective when the air guide plate is in the third position. The third position refers to the position where the air guide plate 100 is rotated upwards to its limit, that is, when the air guide plate 100 is rotated upwards to its maximum angle. At this point, the air guide plate 100 blocks the space above the air conditioner's air 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 the heating effect. (See attached diagram.) Figure 8 and attached Figure 9 It can be seen that after the first guide post 51 enters the second guide section 532, the transmission mechanism 3 and the air guide plate 100 begin to move in opposite directions. At the same time, the second guide post 52 also begins to enter the second guide track 54. Next, the first guide post 51 gradually disengages from the second guide section 532, and the second guide post 52 begins to play a "leading role." The extension trajectory of the second guide track 54 is also arc-shaped. The inner wall of the second guide track 54 generates a torque on the second guide post 52, driving the second auxiliary connecting rod 34 to continue rotating along the predetermined trajectory until the air guide plate 100 rotates to... Figure 10 and Figure 11 The third position in the process completes the entire movement of the air guide plate 100.

[0068] As can be seen from the above, the cooperation between the first guide post 51 and the first guide rail 53 causes the air guide plate 100 to rotate within a first angular range, and the cooperation between the second guide post 52 and the second guide rail 54 causes the air guide plate 100 to rotate within a second angular range. The first angular range refers to the range of angles from the initial state to the downward rotation to the limit position state, and the second angular range refers to the range of angles from the initial state to the upward rotation to the limit position state.

[0069] Combination Figure 3 and Figure 4 It should be noted that, along the direction perpendicular to the second sidewall 121, the height of the second guide rail 54 is less than the height of the first guide rail 53, and the length of the first guide post 51 is less than the length of the second guide post 52. This is to ensure that the first guide post 51 does not interfere with the second guide rail 54 during its rotation after disengaging from the first guide rail 53, and that the first guide post 51 and the second guide post 52 move independently without affecting each other.

[0070] Reference Figure 5 In one embodiment of this application, the end of the first guide rail 53 furthest from the opening end of the housing 1 is closed, and the end of the second guide rail 54 near the opening end of the housing 1 is also closed. Thus, the first guide rail 53 limits the initial position of the first guide post 51, and the second guide rail 54 limits the initial position of the second guide post 52, thereby limiting the entire extension and retraction stroke of the air guide plate 100. This facilitates control of the beginning and end points of the stroke and also prevents the first guide post 51 or the second guide post 52 from slipping out of the corresponding guide rail due to unforeseen circumstances.

[0071] As can be seen from the above, by adopting the technical solution of this application, after the air conditioner is started and running, the driver 4 drives the base plate 2 and the transmission mechanism 3 to translate, while the guide structure controls the synchronous rotation of the second auxiliary connecting rod 34 and the first auxiliary connecting rod 33 in the transmission mechanism 3 to control the relative movement of the first main connecting rod 31 and the second main connecting rod 32, so that the air guide plate 100 extends in a compound motion combining translation and rotation. In this way, during the rotation of the air guide plate 100, a sufficient gap is formed between its edge and the air outlet of the air conditioner, so the rotation angle range of the air guide plate 100 is wider, thereby meeting the higher usage needs of users and improving the user experience.

[0072] On the other hand, in this application, the rotation of the air guide plate 100 is achieved by the torque generated by the guide rail on the guide column, which causes the second auxiliary connecting rod 34 and the first auxiliary connecting rod 33 to rotate passively, thus eliminating the need for additional driving force. That is, this application achieves both translation and rotation of the air guide plate through a single driving element, which simplifies the overall structure of the driving device and reduces costs.

[0073] As described above, although the above embodiments of this application exemplify the use of a guide post including a first guide post 51 and a second guide post 52, and a guide rail including a first guide rail 53 and a second guide rail 54, this application does not limit the number of guide posts and guide rails, or the form of cooperation between the guide posts and guide rails. As long as the extension trajectory of the guide rail is set at an angle to the first direction at at least part of its tangent direction, the motion of the guide post can be decomposed into a motion component along the first direction and a motion component perpendicular to the first direction. In this way, the guide post can generate a torque on the second auxiliary link 34 during the sliding process along the guide rail, thereby driving the second auxiliary link 34 and the first auxiliary link 33 to rotate synchronously.

[0074] This application also discloses an air conditioner, which includes an indoor unit, a driving device for the air guide plate in any of the above embodiments, and an air guide plate installed on the driving device. Specifically, the air guide plate is hinged to the first main connecting rod 31 and the second main connecting rod 32 respectively. The indoor unit has an air outlet. When the air conditioner is started, the driving device is activated, driving the air guide plate to translate and rotate through the first main connecting rod 31 and the second main connecting rod 32. When the air conditioner is not in operation, the air guide plate closes the air outlet of the air conditioner.

[0075] It should be noted that the driving device for the air guide plate in this application can be installed on the side surface of the indoor unit of the air conditioner, or at the end of the internal space of the indoor unit. Those skilled in the art can determine the specific form according to actual production and processing needs. Alternatively, in some other implementations, one of the covers of the casing 1 in this application can also be replaced by the inner wall of the indoor unit of the air conditioner, etc. Any modifications to the specific structure and installation form of the driving device mentioned above, as long as they do not deviate from the technical principles of this application, should be within the protection scope of this application.
