Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a swing blade assembly and an air conditioner. Background Art

[0002] In actual use, the swing blades of the air outlet of the air conditioner cabinet need to be fixed to the air conditioner at both ends in the length direction, and at least one end is connected to the motor drive to drive the swing blade to rotate and change the wind direction. In current production practice, the swing blades are often designed to have low overall strength or low local structural strength during installation. During installation, after assembling one end of the swing blade, it is manually bent to deform it and shorten the total length to complete the assembly of the other end. Then the external force is released, the length of the swing blade is restored, and the assembly operation is completed.

[0003] The above design and installation process has the following shortcomings: First, there are great restrictions on the materials selected for the pendulum blades. As mentioned above, materials with lower strength must be selected; Second, since the pendulum blades are subjected to external forces and deformed during the installation process, if the shape of the pendulum blades is not fully restored, gaps may appear after installation, or problems such as jamming may occur during operation. Utility Model Content

[0004] In order to overcome the existing problems of material selection limitation caused by the installation process of the swing blade and damage of the swing blade during installation, the utility model provides a swing blade assembly.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The swing blade assembly includes a swing blade, at least one end of which in the length direction is drivingly connected to the motor output shaft of the motor, at least one connecting plate is arranged on the swing blade, the connecting plate is arranged at the end where the swing blade is connected to the motor, a clearance groove is provided on the connecting plate, the clearance groove is a strip groove, for the swing blade and the motor output shaft to be assembled; it also includes a limiting member detachably connected to the connecting plate, after the limiting member and the connecting plate are connected, the relative movement between the motor and the swing blade is limited.

[0007] In the present application, a connecting plate is provided on the end of the pendulum blade connected to the motor, and a clearance groove is provided on the connecting plate. Specifically, the clearance groove is a strip groove, and the direction of the clearance groove is consistent with the assembly direction of the pendulum blade relative to the motor. Therefore, during assembly, one end of the pendulum blade is first assembled along the length direction, and then one end of the connecting plate provided as above is assembled. Since the clearance groove is provided on the connecting plate in the present application, the pendulum blade can be assembled without deformation or with very small deformation. Furthermore, since the pendulum blade needs to rotate during operation, in order to avoid the pendulum blade from moving along the assembly direction with the motor during operation, that is, relative movement between the pendulum blade and the motor output shaft, in the present application, a limiter detachably connected to the connection plate is also provided. When the pendulum blade is in the working position, that is, after the assembly of the pendulum blade and the motor is completed, the limiter is connected to the connection plate to prevent the pendulum blade from falling out.

[0008] Obviously, both ends of the swing blade in the length direction can be connected to the motor output shaft. Furthermore, connecting plates and limit members can be provided at both ends of the swing blade as described above.

[0009] Here, the limiter and the connecting plate are detachably connected, and common methods include threaded connection, snap connection, plug-in connection, etc.

[0010] Through the above scheme, in the present application, since the swing blades are prevented from being significantly deformed during assembly, the material selection of the swing blades is less restricted, and is specifically not limited to the low-strength materials in the background technology; damage to the swing blades during installation is also avoided.

[0011] In some embodiments, an adapter part is also included. The adapter part and the motor are located on different sides of the connecting plate. A matching hole is provided on the adapter part. The matching hole of the adapter part is drivingly connected to the output shaft of the motor. The adapter part is detachably connected to the swing blade.

[0012] In this embodiment, an adapter is added to transmit torque. Specifically, the adapter is connected to the motor drive. After the adapter is connected to the motor drive, it is connected to the swing blade to disperse the local force on the swing blade. When the adapter is not provided, the motor and the swing blade are directly driven and connected, specifically through the aforementioned connecting plate. At this time, when the swing blade rotates, the connecting plate is locally subjected to excessive force, and there is a risk of local deformation or even cracking. The adapter is added here, and part or all of the force on the connecting plate can be transferred to the main body of the swing blade through the adapter. Part or all of the difference here lies in the width of the clearance groove, which is specifically reflected in whether the clearance groove contacts the output shaft of the motor after the swing blade and the motor are assembled.

[0013] Here, the adapter is connected to the motor output shaft in a driving manner. Combined with the above content, it can be seen that the matching direction of the adapter and the motor output shaft should be consistent with the axial direction of the motor output shaft. Here, the adapter and the swing blade are detachably connected. For example, after the adapter is connected to the motor in a driving manner, it is fixed to the swing blade by bolts, pins, and other structures.

[0014] In some embodiments, the adapter is slidably connected to the pendulum blade, and a sliding groove is provided on the mating surface of the sliding connection between the pendulum blade and the adapter. The sliding direction of the adapter relative to the pendulum blade is consistent with the axial direction of the motor output shaft. The adapter slides relative to the pendulum blade to realize the driving connection between the adapter and the motor.

[0015] In this embodiment, it is further defined that the adapter part is slidably connected to the swing blade, and the drive connection between the adapter part and the motor is realized during the sliding process of the adapter part relative to the swing blade, that is, the position of the drive connection between the adapter part and the motor is on the sliding stroke of the adapter part, thereby simplifying the process of the drive connection between the adapter part and the motor.

[0016] In some embodiments, the mating surface of the transition portion and the swing blade in sliding connection is a thin-walled elastic structure, and the thin-walled elastic structure is deformed under pressure to be placed in the slide groove.

[0017] In this embodiment, the detachable structure of the adapter and the swing blade is specifically limited. The adapter includes a thin-walled elastic structure. The thin-walled elastic structure is pressed to achieve the disassembly and assembly of the adapter relative to the swing blade. It can be coordinated with the aforementioned sliding connection and has a simple structure.

[0018] In some embodiments, limiting bosses are provided on both sides of the thin-walled elastic structure, and limiting cards are correspondingly provided on both sides of the slide groove. When the adapter part is connected to the motor drive, the limiting bosses and the limiting cards cooperate to limit the adapter part from sliding along the slide groove.

[0019] In this embodiment, a limiting boss and a limiting card are additionally provided to prevent the adapter from sliding along the upper slide groove of the swing blade after the adapter is connected to the motor drive, thereby preventing the swing blade from being disconnected from the motor.

[0020] In some embodiments, the adapter and the limiting member are integrally provided.

[0021] In this embodiment, the adapter and the limiting member are integrally provided to simplify the structure and the assembly process.

[0022] In some embodiments, a limiting groove is further provided on the connecting plate, and the limiting member is inserted into the limiting groove.

[0023] In this embodiment, the connection plate and the limit member are specifically restricted to plug-in connection, which simplifies the fixing method of the limit member and facilitates assembly; in the solution in which the adapter and the limit member are integrally arranged, the plug-in connection of the limit member can be achieved during the assembly process of the adapter and the motor.

[0024] In some embodiments, the limiting groove at least includes a strip-shaped groove segment, and the strip-shaped groove segment of the limiting groove is perpendicular to the giving way groove.

[0025] In this embodiment, the strip groove section of the limit groove is perpendicular to the clearance groove because the limit groove is used for the plug-in assembly of the limit member. The limit member is mainly used to prevent the swing blade and the motor from moving along the clearance groove direction. The setting of the limit groove here has the function of dispersing the force.

[0026] In some embodiments, both ends of the swing blade in the length direction are drivingly connected to the motor output shaft of the motor, and connecting plates and limit members are provided at both ends.

[0027] In this embodiment, both ends of the swing blade are connected to the motor drive, and correspondingly, connecting plates and limit members can be set at both ends as above.

[0028] The utility model also provides an air conditioner, comprising the swing blade assembly described in any one of the above embodiments.

[0029] The beneficial effects of the utility model are:

[0030] 1. By setting a connecting plate at one end of the swing blade and the motor drive connection, and then adding a clearance groove on the connecting plate, it is convenient to assemble the swing blade and the motor, so that the swing blade does not need to be deformed or the deformation is very small during the assembly process, thereby breaking through the selection restrictions of the swing blade material and avoiding damage to the swing blade during assembly; adding a limiter to avoid the position of the swing blade being offset during operation due to the opening of the clearance groove.

[0031] 2. By adding a transition part, the local excessive force on the swing blade connecting plate can be avoided; the transition part and the swing blade are slidably connected, and the connection position between the transition part and the motor drive is located on the sliding stroke, which simplifies the overall structure and assembly process; the transition part cooperates with the swing blade through a deformable thin-walled elastic structure, so that the transition part as a whole is detachable; limit cards and limit bosses are respectively provided on the thin-walled elastic structure and the swing blade, which facilitates the limiting of the transition part after the connection with the motor drive.

[0032] 3. By adding a limit groove on the connecting plate, the limit groove is used for the limit piece to be inserted, thereby simplifying the matching process of the limit piece and the connecting piece; further, the limit groove and the give way groove are opened in perpendicular directions to disperse the force; further, the adapter and the limit piece are integrally arranged, and when the adapter and the motor are assembled in place, the limit piece is also in place to simplify the assembly process.

DETAILED DESCRIPTION

[0042] The utility model is further described below in conjunction with the accompanying drawings.

[0043] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0044] like Figure 1-Figure 7 As shown, the utility model provides a swing blade assembly and also provides an air conditioner including the swing blade assembly.

[0045] like Figure 1 As shown, in this embodiment, the air conditioner 6 is a vertical air conditioner, and the vertical air conditioner 6 is equipped with two swing blades 1, and the two swing blades 1 are vertically installed on the air conditioner 6.

[0046] Obviously, the type of air conditioner 6 and the number of swing blades 1 are exemplary and are not intended to be a specific limitation. The swing blades 1 are vertically mounted on the air conditioner 6, depending on the type of air conditioner 6, which is not specifically limited here.

[0047] like Figure 2 As shown in FIG. 1 , the installation position of the swing blade assembly is shown. In this embodiment, as shown in FIG. Figure 2As shown, both ends of the swing blade 1 along the length direction are drivingly connected to the motor 2. Specifically, both ends are drivingly connected to the motor output shaft 21, so that the motor 2 drives the swing blade 1 to rotate.

[0048] Obviously, in this embodiment, both ends of the swing blade 1 along the length direction are connected to the motor 2. In some embodiments, one end of the swing blade 1 along the length direction is connected to the motor 2, and the other end is connected to the air conditioner 6 housing, which is not specifically limited here.

[0049] like Figure 3 As shown, in this embodiment, a connecting plate 3 is provided on the swing blade 1, one side of the connecting plate 3 is the motor 2, and the other side is additionally provided with a connecting portion 5, which is used to transmit torque to drive the swing blade 1 to rotate.

[0050] like Figure 4-7 As shown, the details of the swing blade assembly provided by this embodiment are specifically demonstrated.

[0051] like Figure 6 As shown, a clearance groove 31 is opened on the connecting plate 3, and the clearance groove 31 is used for assembling the swing blade 1 and the motor 2. Specifically, the clearance groove 31 is a strip groove, and the opening direction of the clearance groove 31 is consistent with the assembly direction of the swing blade 1 relative to the motor 2.

[0052] Combination Figure 2 As shown, although in this embodiment, both ends of the swing blade 1 along the length direction are connected to the motor 2 for driving, the structures of the two ends are different. Figure 3 As shown, in this embodiment, the swing blade 1 is provided with the give way groove 1, the transition part 5 and the like provided in this embodiment at one end along the length direction, and the other end can be implemented according to the prior art.

[0053] In this way, during the installation process, one end implemented according to the prior art is first installed, the swing blade 1 is directly connected to the motor output shaft 21, and then the other end of the swing blade 1 is assembled. When assembling the other end, since the end connecting plate 3 is provided with a clearance groove 31, the swing blade 1 is slightly deformed and can be installed in the working position.

[0054] According to the above implementation, compared with the prior art, a significant deformation of the pendulum blade 1 during the installation process is avoided, thereby breaking through the selection restrictions of the material of the pendulum blade 1 and avoiding damage to the pendulum blade 1 during assembly.

[0055] Obviously, in this embodiment, since both ends of the pendulum blade 1 in the length direction are driven and connected to the motor 2 in this application, connecting plates 3 and clearance grooves 31 can be set at both ends of the pendulum blade 1 in the length direction, so that the pendulum blade 1 will not be deformed during installation.

[0056] In this embodiment, since a clearance groove 31 is provided on the connecting plate 3, in order to prevent the swing blade 1 from deviating from the normal operating position during operation, thereby preventing the swing blade 1 and even the air conditioner 6 components from being damaged, a limit member 4 detachably connected to the connecting plate 3 is provided in this embodiment.

[0057] Specifically, the limiter 4 has multiple implementations. For example, after the swing blade 1 and the motor 2 are driven and connected, the limiter 4 is connected to the connecting plate 3. Specifically, the limiter 4 is located above the motor output shaft 21, so that the swing blade 1 cannot be offset along the clearance groove 31. It is obvious here that the limiter 4 can be a separate component, which can be detachably connected to the connecting plate 3 by bolt connection, snap connection, plug connection, etc.

[0058] In this embodiment, the preferred position-limiting member 4 is plug-in-connected with the connecting plate 3. In this application, plug-in means that the position-limiting member 4 and the groove on the connecting plate 3 are interference fit.

[0059] Obviously, the limit member 4 can be set to be directly plugged into the upper part of the clearance groove 31. However, in practice, the limit member 4 may be subjected to a force in the direction of the clearance groove 31. In order to ensure the effectiveness of the limit member 4, preferably, a limit groove 32 should be specially opened for the insertion of the limit member 4.

[0060] Furthermore, in this embodiment, in combination with the aforementioned giving way groove 31 being a strip groove, the limiting groove 32 also includes at least a strip groove section, and the strip groove section of the limiting groove 32 is perpendicular to the giving way groove 31, so as to facilitate the force distribution between the limiting groove 32 and the limiting member 4.

[0061] More specifically, in this embodiment, the preferred limiting groove 32 is selected to be an I-shaped groove, and the positioning groove 31 is located in the middle of the limiting groove 32, such as Figure 6 Obviously, the above-mentioned effect can also be achieved by selecting the limiting groove 32 to be in a straight line shape. When the limiting groove 32 is in a straight line shape, the limiting groove 32 and the giving way groove 31 are in a "+" shape as a whole.

[0062] Obviously, the outer dimensions of the limiting member 4 are adapted to the outer dimensions of the aforementioned limiting groove 32 so as to provide a larger contact area.

[0063] like Figure 7 and Figure 8 As shown, in this embodiment, a transfer part 5 is also provided, and the transfer part 5 is used to transmit the torque of the motor 2 so that the motor 2 can drive the swing blade 1 to rotate. Therefore, the transfer part 5 contains a matching hole 51, and the matching hole 51 is used to match with the motor output shaft 21 to achieve a driving connection.

[0064] It is easy to understand that here, since the adapter part 5 is added to transmit torque, instead of the yield groove 31 on the aforementioned connecting plate directly cooperating with the motor output shaft 21 to transmit torque, it is convenient for the adapter part 5 to disperse the torque to the main body of the swing blade 1 instead of concentrating the force on the connecting plate 3.

[0065] Accordingly, the structure of the adapter 5 is smaller, and a material with higher hardness can be used to avoid local deformation or cracking at the connecting plate 3. Obviously, in the embodiment without the adapter 5, at least a part of the clearance groove 31 is matched with the motor output shaft 21 to transmit torque; after the adapter 5 is added, the clearance groove 31 can only play the role of facilitating the matching and passing the motor output shaft 21. The adapter 5 is used to transmit torque, and the size of the clearance groove 31 is less restricted.

[0066] Obviously, the adapter 5 is to be drivingly connected to the motor 2 , and the matching direction is that the adapter 5 moves along the axial direction of the motor output shaft 21 .

[0067] Furthermore, since the travel direction of the adapter 5 is determined, the adapter 5 is preferably slidably connected to the swing blade 1. Specifically, a slide groove 11 is provided on the swing blade 1 for assembling the adapter 5 and the motor output shaft 21. At this time, when the adapter 5 slides relatively along the slide groove 11, it can be assembled with the motor output shaft 21.

[0068] Furthermore, the adapter 5 is detachably connected to the swing blade 1, and there are multiple specific implementations. For example, after the adapter 5 is driven and connected to the motor 2, it is fixed to the swing blade 1 by bolts, pins, etc.

[0069] In this embodiment, the mating surface of the adapter 5 and the swing blade 1 for sliding connection is a thin-walled elastic structure 52. By pressing both sides of the thin-walled elastic structure 52, it can be placed in the slide groove 11 to achieve a detachable connection between the adapter 5 and the swing blade 1, and the structure is simple.

[0070] Further, such as Figure 4 As shown, in this embodiment, limiting bosses 521 are provided on both sides of the thin-walled elastic structure 51, and correspondingly, limiting clamps 111 are provided on both sides of the slide slot 11. When the matching hole 51 of the adapter 5 is matched with the motor output shaft 21, the limiting clamps 111 and the limiting bosses 521 cooperate to limit the adapter 5 from moving along the slide slot 11 in a direction away from the motor output shaft 21, thereby preventing the adapter 5 from failing during implementation and failing to transmit torque.

[0071] In this embodiment, the adapter 5 and the limiting member 4 are integrally arranged. Figure 7 As shown, at this time, the sliding process of the adapter 5 along the slide groove 11 can not only realize the matching of the matching hole 51 of the adapter 5 and the motor output shaft 21, but also simultaneously complete the insertion of the limiter 4.

[0072] Obviously, even if the limiting member 4 is not connected to the connecting plate 3 by plugging, for example, it is fixed to the connecting plate 3 by bolts, the limiting member 4 and the adapter 5 can also be provided as an integral unit, which will not be described in detail here.

[0073] Combination Figure 4 and Figure 5 As shown, when the adapter 5 and the motor 2 complete the driving connection, the limiting member 4 and the limiting groove 32 cooperate with each other, and the position of the swing blade 1 is offset during the blocking operation.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
