[0017] Air duct skeleton;

[0018] As described above, the swing blade component, the air duct frame is provided with a mounting groove, the motor is located in the mounting groove, and the bracket cover is arranged at the notch of the mounting groove.

[0019] The swing blade component of the embodiment of the utility model is mainly composed of a swing blade, a bracket and a motor.

[0033] 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 clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] When the air conditioner is cooling, the wind passes through the heat exchange of the evaporator and becomes cold wind, which is blown out from the air duct opening. The air duct opening is generally provided with left and right swing blades to realize wide-area air supply of the air conditioner. Many swing blade movement modes are that an active swing blade drives the driven swing blade to realize automatic left and right rotation through the rotation of a stepper motor. Since it is on the lower side of the air duct and the swing blade is a rotating component, a designed gap is left, and it is inevitable that wind leaks in. The motor will heat up when it moves, causing cold wind to blow onto the heated motor during cooling, condensing water, and there is a risk of motor damage. The common solution in the prior art is to add a sealing rubber sleeve to the stepper motor, but it will cause the heat of the motor to not be dissipated and increase the assembly cost.

[0035] like Figures 1 to 5 As shown, the pendulum blade component provided by the embodiment of the utility model includes a pendulum blade 100, a bracket 200 and a motor 300. The pendulum blade 100 includes a pendulum blade body 110 and a mounting plate 120. The pendulum blade body 110 is provided with a connecting hole 111. The mounting plate 120 is axially arranged around the connecting hole 111 and connected to the pendulum blade body 110. A bending gap 400 is formed on the contact surface between the bracket 200 and the mounting plate 120. The motor 300 and the mounting plate 120 are respectively located on both sides of the bracket 200. The driving shaft 310 of the motor 300 is connected to the connecting hole 111, which is suitable for driving the mounting plate 120 to rotate relative to the bracket 200.

[0036] The swing blade component of the embodiment of the utility model is mainly composed of a swing blade 100, a bracket 200 and a motor 300. The bracket 200 is used to support the installation of the swing blade 100 and separate the main body of the motor 300 from the swing blade 100. The swing blade 100 is composed of a swing blade body 110 and a mounting plate 120. The bracket 200 is provided with a mounting hole 220. The motor 300 and the swing blade body 110 are both arranged corresponding to the mounting hole 220, and the driving shaft 310 of the motor 300 passes through the mounting hole 220 and is connected to the swing blade body 110. The blade body 110 is connected to the connecting hole 111, and the mounting plate 120 is arranged on the swing blade body 110 and is axially arranged around the connecting hole 111. The lower surface of the mounting plate 120 contacts the upper surface of the bracket 200, and is affected by the configuration of the mounting plate 120 and the bracket 200. The contact surfaces of the two can form a bending gap 400. The swing blade body 110 is driven by the motor 300 to swing within a certain angle range, and at the same time, the mounting plate 120 can be driven to rotate relative to the bracket 200.

[0037] The bracket 200 is a part of the air duct. Due to the bending gap 400 formed between the bracket 200 and the mounting plate 120, when the cold air in the air duct passes through the swing blade 100, the cold air needs to enter the bending gap 400 to reach the mounting hole 220 of the mounting plate 120, and contact the motor 300 through the mounting hole 220. The design of the bending gap 400 can increase the length and bending degree of the cold air flow path. The cold air needs to turn several times in multiple directions during the process of flowing into the bending gap 400, thereby effectively blocking the cold air from flowing into the mounting hole 220 and preventing the cold air from reaching the motor 300. Since there is no negative pressure suction at the motor 300, when the cold air passes through the bracket 200 and the swing blade 100, it will be blocked by the structure formed by the bracket 200 and the mounting plate 120, thereby solving the condensation at the swing blade 100 and preventing the motor 300 from being damaged.

[0038] According to an embodiment provided by the utility model, the mounting plate 120 is provided with at least one first mounting portion 121, and the bracket 200 is provided with a second mounting portion 210 cooperating with the first mounting portion 121. One of the first mounting portion 121 and the second mounting portion 210 is a protrusion, and the other is a groove. The protrusion is embedded in the groove and can slide along the groove. The surface of the protrusion and the surface of the groove enclose a bending gap 400.

[0039] In this embodiment, a first mounting portion 121 is provided on the mounting plate 120, and a second mounting portion 210 is provided on the bracket 200. The first mounting portion 121 and the second mounting portion 210 are structures that cooperate with each other, one of which is a groove and the other is a protrusion. The protrusion can be embedded in the groove. When the motor 300 drives the swing blade 100 to rotate, the protrusion can slide synchronously in the groove. The interlocking structure of the protrusion and the groove can form a bending gap 400 between the surface of the bracket 200 and the surface of the mounting plate 120.

[0040] In this embodiment, the cross-sectional shape of the protrusion is a rectangle, and the structural coordination of the protrusion and the groove can maximize the bending amplitude of the bending gap 400. After entering the bending gap 400, the cold air will pass through the gaps in the horizontal and vertical directions, that is, it will flow horizontally and upward and downward repeatedly. As the path bends, the cold air will gradually dissipate, and the gap will block the cold air to the greatest extent.

[0041] In some embodiments, the first mounting portion 121 and the second mounting portion 210 can be matched with each other by arbitrarily selecting the arrangement form of protrusions and grooves, that is, the bracket 200 and the mounting plate 120 can have both protrusions and grooves.

[0042] In some embodiments, the structure of the bending gap 400 can also be determined by the structural form of the bracket 200 and the mounting plate 120 , such as the upper surface of the bracket 200 is a corrugated surface, and the lower surface of the mounting plate 120 is a corrugated surface that matches the upper surface of the bracket 200 .

[0043] According to an embodiment provided by the utility model, the first mounting portion 121 includes a first protrusion 122 and a second protrusion 123, both of which are arc-shaped protrusions, and the first protrusion 122 and the second protrusion 123 are centrally symmetrically arranged with the axis of the connecting hole 111 as the center, and a gap 124 is provided between the end of the first protrusion 122 and the end of the second protrusion 123 opposite to it.

[0044] In this embodiment, the first mounting portion 121 is a protrusion, and is composed of a first protrusion 122 and a second protrusion 123. The first protrusion 122 and the second protrusion 123 are both arc-shaped protrusions, which are centrally symmetrically arranged around the connecting hole 111, that is, the two arc-shaped protrusions are arranged in a circle, and the first protrusion 122 and the second protrusion 123 are opposite to each other and have a gap 124 of a certain distance at the end position to ensure that a space for mold removal is formed during the manufacturing process. The arc-shaped protrusion has a certain length, and can form a certain range of bending gaps 400 within the range where the mounting plate 120 is located, thereby blocking cold air from entering the mounting hole 220 of the bracket 200 within a larger range.

[0045] In some embodiments, the arc-shaped first protrusion 122 and the second protrusion 123 and the second mounting portion 210 cooperating therewith may also be an arc-shaped groove, and the two arc-shaped grooves respectively cooperate with the first protrusion 122 and the second protrusion 123. In the process of the motor 300 driving the swing blade 100 to rotate, the arc-shaped protrusion can also slide in the arc-shaped groove, thereby achieving the effect of blocking the cold wind, and at the same time ensuring the relative rotation of the mounting plate 120 and the supporting component without affecting the swinging movement of the swing blade 100.

[0046] According to an embodiment provided by the utility model, the motor 300 is suitable for driving the swing blade body 110 to swing between an initial position and a final position, and in the final position, the first mounting portion 121 is at least partially oriented toward the front of the air duct outlet. In this embodiment, the swing blade body 110 can swing between the initial position and the final position under the drive of the motor 300, and the final position is the extreme angle of the swing of the swing blade 100, that is, when the swing blade 100 swings to the maximum angle, the first mounting portion 121 can extend to the front range of the air duct outlet.

[0047] At the extreme position of the swing of the swing blade 100, the bending gap 400 formed by the first mounting portion 121 and the second mounting portion 210 can also cover the front range of the air duct outlet, ensuring that the bending gap 400 can always block the cold wind during the swing process from the initial position to the final position, and the blocking is sufficient without missing any blind spots.

[0048] According to an embodiment provided by the utility model, the mounting plate 120 is provided with two first mounting portions 121, and the two first mounting portions 121 are arranged sequentially from the inside to the outside along the radial direction of the connecting hole 111, and the bracket 200 is provided with two second mounting portions 210, and the second mounting portions 210 are arranged one-to-one with the first mounting portions 121, and the second mounting portions 210 are annular grooves.

[0049] In this embodiment, there are two first mounting parts 121, each of which is composed of a first protrusion 122 and a second protrusion 123. The two first mounting parts 121 are arranged in parallel with each other, and one first mounting part 121 is closer to the swing blade body 110 than the other first mounting part 121, that is, a total of four protrusions are arranged on the mounting plate 120, two by two in a group, arranged oppositely and distributed symmetrically in the center. After the two protrusions on the same side are assembled with the corresponding grooves on the bracket 200, the surfaces of the protrusions and the grooves, as well as the surfaces between the protrusions and the grooves, form a bending gap 400 together, thereby forming a labyrinth-like sealing structure.

[0050] The groove is configured as an annular through groove structure. Compared with an arc groove, an annular groove is easier to manufacture and does not limit the rotation of the mounting plate 120, thereby ensuring the smoothness of the rotation of the swing blade 100. The first protrusion 122 and the second protrusion 123 are both located in an annular groove, and the second mounting portion 210 is two, and the corresponding two annular grooves are sleeved.

[0051] When the cold air from the air duct wants to enter, it needs to turn 8 times in various directions in the maze-like sealing structure before reaching the motor 300, so that the cold air is blocked like entering a maze and cannot enter smoothly, thereby reducing the risk of condensation at the motor 300 position of the swing blade component and increasing the service life of the motor 300.

[0052] In some embodiments, the number of the first mounting portions 121 can be selected according to actual needs, and the specific structure of the first mounting portions 121 can also be a combination of grooves and protrusions according to actual needs.

[0053] According to an embodiment provided by the utility model, the width of the bending gap 400 is between 0.025 and 0.15 mm. In this embodiment, the width of the bending gap 400 refers to the vertical distance between the matching surfaces. The width of the bending gap 400 surrounded by the surface of the protrusion and the surface of the groove is 0.1 mm, and the width of the bending gap 400 surrounded by the surface between the protrusions on the mounting plate 120 and the surface between the grooves on the bracket 200 is 0.03 mm. Controlling the width of the bending gap 400 within a certain range can effectively block cold wind.

[0054] According to an embodiment of the present invention, a rough portion is provided on the surface of the bracket 200 at the position where the bending gap 400 has the smallest width. In this embodiment, when the mounting plate 120 rotates relative to the bracket 200, in order to prevent abnormal noise during rotation, the rough portion is provided at a position where the mounting plate 120 is closer to the bracket 200, that is, at a position where the bending gap 400 is the smallest.

[0055] In this embodiment, the rough portion may be a leather grain surface, that is, the width of the bending gap 400 enclosed by the surface between the protrusions on the mounting plate 120 and the surface between the grooves on the bracket 200 is 0.03 mm, and the surface of the bracket 200 corresponding to this position is made into a leather grain surface.

[0056] According to an embodiment of the present invention, the swing blade body 110 and the mounting plate 120 are an integrated structure. In this embodiment, the swing blade body 110 and the mounting plate 120 are an integrated structure, which improves the structural strength of the swing blade 100 and facilitates the installation of the swing blade 100 and the motor 300.

[0057] In some embodiments, the bracket 200 is provided with a slot body that matches the shape of the mounting plate 120. When the swing blade 100 is connected to the motor 300, the mounting plate 120 is entirely embedded in the slot body, and the upper surface of the mounting plate 120 is flush with the bracket 200. The lower surface of the bracket 200 may be provided with a mounting structure for fixed connection with the motor 300.

[0058] According to an embodiment provided by the utility model, a waterproof cover is further provided on the outer wall of the motor 300. In this embodiment, a waterproof cover can also be provided on the outer wall of the motor 300 to further prevent condensation on the surface of the motor 300 and damage to the motor 300.

[0059] The embodiment of the utility model also provides an air conditioner, including an air duct frame 500 and the above swing blade component, the air duct frame 500 is provided with a mounting groove 510, the motor 300 is located in the mounting groove 510, and the bracket 200 covers the notch of the mounting groove 510.

[0060] The air conditioner of the embodiment of the utility model has an integrated bracket 200 at the lower end of the air duct frame 500. As a part of the air duct, the swing blade 100 is installed on the bracket 200. The motor 300 uses a stepper motor 300. The motor 300 is located in a mounting groove 510 at the lower end of the air duct. The mounting groove 510 has a storage space for the motor 300.
