Referring to fig. 1-5, the shutter assembly 20 may include a plurality of shutters 1 and links 2 disposed at intervals, each shutter 1 rotatably provided at both ends thereof on opposite side walls of the support frame 10. For example, referring to fig. 1 and 6 to 13, a first rotation shaft 15 and a second rotation shaft 16 are provided at both ends of each louver 1, and first mounting holes (not shown) and second mounting holes (not shown) respectively adapted to the first rotation shaft 15 and the second rotation shaft 16 are provided on left and right side walls of the support frame 10, and each louver 1 is rotatable with respect to the left and right side walls of the support frame 10. In the description of the present invention, "a plurality of" means two or more.
Referring to fig. 6 to 13, each louver 1 is provided with a first engaging portion 11, and each louver 1 is provided with a recess 12 that opens toward the first engaging portion 11. The connecting rod 2 is provided with a plurality of second matching parts 21, the second matching parts 21 are respectively matched with the first matching parts 11 in a one-to-one correspondence manner so as to drive the shutters 1 to synchronously rotate, and when the shutters 1 rotate to a set angle, a part of the connecting rod 2 is accommodated in the avoidance groove 12 of each shutter 1. Therefore, when the louver 1 rotates to a preset angle, a part of the connecting rod 2 is contained in the avoidance groove 12 of each louver 1, so that the louver 1 can rotate at a large angle without interfering with the connecting rod 2, and further, the louver 1 can guide and adjust the air outlet of the air conditioner indoor unit 100 to a large extent, and different requirements of customers can be met.
For example, as shown in fig. 1 to 7, 10 and 11, when the louver 1 opens the supporting frame 10 (the louver 1 is positioned as shown in fig. 1 and 2), the escape groove 12 is provided on the upper surface of the louver 1 and extends in the front-rear direction, when the louver assembly 20 closes the supporting frame 10, the link 2 moves downward to drive the plurality of louvers 1 to simultaneously rotate downward to close the supporting frame 10, and when the plurality of louvers 1 rotate downward to an angle to close the supporting frame 10, a part of the link 2 is accommodated in the escape groove 12 of each louver 1;
as another example, as shown in fig. 8, 9, 12 and 13, when the louver 1 opens the supporting frame 10 (the louver 1 is positioned at the position shown with reference to fig. 1 and 2), the escape groove 12 is provided at the lower surface of the louver 1 and extends in the front-rear direction, when the louver assembly 20 closes the supporting frame 10, the link 2 moves upward to drive the plurality of louvers 1 to rotate upward simultaneously to close the supporting frame 10, and when the plurality of louvers 1 rotate upward to an angle to close the supporting frame 10, a portion of the link 2 is accommodated in the escape groove 12 of each louver 1.
In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present invention.
According to the louver assembly 20 for the air conditioner indoor unit 100, when the louver 1 is driven by the connecting rod 2 to rotate to a preset angle, a part of the connecting rod 2 is contained in the avoiding groove 12 of each louver 1, so that the louver 1 can rotate at a large angle without interference with the connecting rod 2, and the louver 1 can guide and regulate the air outlet of the air conditioner indoor unit 100 to a large extent, and different requirements of customers can be met.
In some embodiments of the invention, as shown in fig. 6-9, the end of the relief groove 12 opposite the opening 121 is spaced from the side wall of the blind 1. Therefore, the structure is simple, and the influence of the avoidance groove 12 on the structural strength of the shutter 1 is reduced. For example, as shown in fig. 6 and 7, the escape groove 12 is provided on the upper surface of the louver 1, the escape groove 12 extends in the front-rear direction, and the rear wall of the escape groove 12 is provided at a distance from the rear wall of the louver 1; as another example, as shown in fig. 8 and 9, the escape groove 12 is provided on the lower surface of the louver 1, the escape groove 12 extends in the front-rear direction, and the rear wall of the escape groove 12 is provided at a distance from the rear wall of the louver 1.
Alternatively, as shown in fig. 6 to 9, the depth of the escape groove 12 gradually decreases in a direction toward and away from the opening 121. In other words, the depth of the escape groove 12 gradually increases in the direction toward the first engaging portion 11. Therefore, the structure is simple, the structural strength of the avoidance groove 12 can be ensured, and the influence of the avoidance groove 12 on the structural strength of the shutter 1 can be reduced.
In some embodiments of the invention, referring to fig. 10-13, the end of the relief groove 12 opposite the opening 121 extends to the side wall of the blind 1. Therefore, when the connecting rod 2 drives the shutter 1 to close the supporting frame 10, the volume of the connecting rod 2 accommodated in the avoidance groove 12 can be increased, so that interference between the connecting rod 2 and the shutter 1 is further reduced, and the shutter 1 can be rotated at a large angle. For example, as shown in fig. 10 to 11, a concave portion is provided on the upper surface of the louver 1, which is concave downward, and defines a relief groove 12 penetrating the louver 1 in front and rear; as another example, as shown in fig. 12-13, the lower surface of the shutter 1 is provided with an upwardly concave recess portion, and the recess portion defines a relief groove 12 penetrating the shutter 1 in front and rear directions.
Alternatively, as shown with reference to fig. 10-13, the depth of the relief groove 12 remains unchanged in a direction away from the opening 121. Therefore, when the connecting rod 2 drives the shutter 1 to close the supporting frame 10, the depth of the shutter 1 extending into the avoidance groove 12 can be uniform, interference between the connecting rod 2 and the shutter 1 can be further reduced, and the plurality of shutters 1 can be facilitated to completely close the supporting frame 10.
In some embodiments of the present invention, as shown in fig. 5 and 7, the louver 1 is provided with a guide groove 17 communicating with the opening 121, the guide groove 17 being located between the opening 121 and the first mating portion 11, opposite side walls of the guide groove 17 extending in a direction away from each other in a direction away from the opening 121. Thus, when the plurality of shutters 1 rotate synchronously, the guide groove 17 can guide the connecting rod 2 into or out of the opening 121, thereby being beneficial to preventing the shutter assembly 20 from being blocked.
In some embodiments of the present invention, as shown in fig. 5, the link 2 is formed in a flat plate shape. It can be understood that the periphery of the conventional connecting rod is provided with a flanging, while the connecting rod 2 in the embodiment of the invention is formed into a flat plate shape, that is, the connecting rod 2 in the embodiment of the invention is not provided with a flanging, so that the blocking effect of the connecting rod 2 on the air flow in the air duct can be reduced, and interference between the connecting rod 2 and the shutter 1 can be reduced by avoiding the flanging on the connecting rod 2, which is beneficial to making the running fit between the connecting rod 2 and the shutter 1 stable and reliable.
In some embodiments of the present invention, as shown with reference to fig. 5 to 13, one of the first and second engaging portions 11 and 21 is a pivot shaft, and the other of the first and second engaging portions 11 and 21 is a pivot hole, with which the pivot shaft is in rotation engagement. Therefore, the connection between the plurality of shutters 1 and the connecting rod 2 can be stable and reliable by enabling the pivot shaft to be in running fit with the pivot hole, so that the plurality of shutters 1 and the connecting rod 2 can be conveniently installed and detached. For example, the first fitting portion 11 is a pivot shaft, the second fitting portion 21 is a pivot hole, or the first fitting portion 11 is a pivot hole, and the second fitting portion 21 is a pivot shaft.
In some embodiments of the present invention, referring to fig. 5-13, the diameter of the pivot shaft is D1, the diameter of the pivot hole is D1, D1 satisfies: D1-D1 is less than or equal to 0.1mm and less than or equal to 0.5mm. Therefore, on one hand, the value of D1-D1 is not too large, so that the reliability of the cooperation between the shutter 1 and the connecting rod 2 is ensured, and on the other hand, the value of D1-D1 is not too small, so that the shutter 1 is prevented from being blocked relative to the connecting rod 2 in the rotating process of the shutter assembly 20. For example, the value of D1-D1 may be 0.1mm, 0.2mm, 0.3mm, 0.4mm or 0.5mm.
Alternatively, referring to fig. 5 to 13, the axial length of the pivot shaft is L1 (e.g., the length of the pivot shaft in the left-right direction is L1 as shown in fig. 6), the hole depth of the pivot hole is L2 (e.g., the pivot hole penetrates the link 2 in the thickness direction of the link 2 as shown in fig. 5, the length of the pivot hole in the left-right direction is L2), and L1, L2 satisfy: L1-L2 is more than or equal to 0.5mm and less than or equal to 2.5mm. Therefore, on one hand, the values of L1-L2 are not too large, so that the reliability of the cooperation between the shutter 1 and the connecting rod 2 is ensured, and on the other hand, the values of D1-D1 are not too small, so that the installation cooperation between the pivot shaft and the pivot hole can be realized in the axial direction. For example, the value of D1-D1 may be 0.5mm, 1.0mm or 2.5mm.
In some embodiments of the present invention, as shown in fig. 6-13, the first mating portion 11 is a pivot shaft, the second mating portion 21 is a pivot hole, and a clamping groove is disposed on an end of the pivot shaft facing the shutter 1, and the shutter 1 is clamped in the clamping groove. Thereby, the contact area between the pivot shaft and the corresponding louver 1 is increased, so that the reliability of the connection between the pivot shaft and the corresponding louver 1 can be improved. Optionally, a clamping groove is formed in one end, facing the shutter 1, of the pivot shaft, the shutter 1 is clamped in the clamping groove, and the shutter 1 and the pivot shaft are integrally formed.
Alternatively, referring to fig. 6 to 13, as shown in fig. 2, the end of the pivot shaft protruding from the pivot hole is provided with a drop-off prevention portion 13, and at least part of the drop-off prevention portion 13 has a larger cross-sectional area than the pivot hole. Wherein "the cross-sectional area of at least part of the drop-out preventing portion 13 is larger than the area of the pivot hole" may be understood as that the cross-sectional area of a part of the drop-out preventing portion 13 is larger than the area of the pivot hole, or that the cross-sectional area of the entire drop-out preventing portion 13 is larger than the cross-sectional area of the pivot hole. For example, as shown in connection with fig. 2 and 5 to 13, the cross-sectional area of the portion of the escape prevention part 13 facing the pivot hole is larger than the area of the pivot hole. Thereby, by providing the escape prevention portion 13, the movement of the louver 1 in the axial direction of the pivot shaft can be restricted, so that the pivot shaft can be fitted in the pivot hole stably and reliably.
In some alternative embodiments of the present invention, as shown in fig. 2, each link 2 is further provided with an opening 22 in communication with the pivot hole, and the distance between the opposite side walls of the opening 22 is smaller than the diameter of the pivot hole. Therefore, when the connecting rod 2 is mounted on the shutter 1, the opening 22 is arranged, the pivot Kong Yifa can be deformed to be convenient to fit the pivot shaft into the pivot hole, the outer peripheral wall of the pivot shaft is abutted with the inner peripheral wall of the pivot hole, the pivot shaft is stably and reliably connected with the connecting rod 2, and therefore the shutter 1 and the connecting rod 2 can be conveniently and quickly connected and detached. For example, the cross section of the pivot hole is formed in a circular shape, the cross section of the opening hole 22 is formed in an elongated shape, and the distance between the opposite side walls of the opening hole 22 is smaller than the diameter of the pivot hole, the elongated pivot Kong Yifa is deformed to facilitate fitting the pivot shaft into the pivot hole when the link 2 is mounted to the blind 1, and the outer peripheral wall of the pivot shaft abuts the inner peripheral wall of the pivot hole, and the pivot shaft cannot move into the opening hole 22.
