Detailed Embodiments

[0020] The present utility model will be further described below in conjunction with the accompanying drawings.

[0021] According to Figures 1 - 5 As shown, an embodiment of the present application provides an air conditioner louver link mechanism, which includes a louver bracket 1. A plurality of louvers 2 are arranged at intervals in the length direction of the louver bracket 1. A rotating shaft 4 is provided on the louver 2, and the rotating shaft 4 is rotatably connected to the louver bracket 1. A louver link 3 is provided on one side of the louver bracket 1. The louver link 3 serially connects a plurality of the louvers 2 in sequence, and the louver 2 is rotatably connected to the louver link 3. A driving end 5 is provided on the louver link 3. An elastic buckle 8 and a positioning post 9 are provided at the driving end 5. A swing rod 6 is connected to the driving end 5. A clamping groove 10 and a positioning groove 11 are provided on the swing rod 6. The clamping groove 10 is in clamping fit with the elastic buckle 8. The positioning post 9 is adapted in shape to the positioning groove 11 and is in plug-in fit. The positioning post 9 is in the shape of a polygonal prism, that is, the cross-section is a polygon, and the cross-section can also be a multi-pointed star, which can ensure that the positioning post 9 and the positioning groove 11 do not rotate relative to each other. A driving component 7 for driving the swing rod 6 to move is connected to the side of the swing rod 6 away from the driving end 5.

[0022] First of all, it should be stated that the elastic clamping is realized through the elastic buckle 8 and the clamping groove 10 to ensure the fixed connection effect. Moreover, through the setting of the positioning post 9 in the shape of a polygonal prism, it can be ensured that there is no relative rotation between the positioning post 9 and the positioning groove 11. The connection between the swing rod 6 and the louver link 3 is more stable and reliable, realizing a stable transmission effect, being able to reduce the risk of the failure of the moving mechanism, and the elastic buckle 8 and the positioning post 9 facilitate the disassembly between the swing rod 6 and the louver link 3.

[0023] During normal operation, the driving component 7 drives the swing rod 6 to achieve stable reciprocating swing. The swing amplitude and direction are controlled by the driving component 7. The swing rod 6 can drive the louver link 3 to achieve synchronous movement in the length direction and the width direction through the cooperation of the positioning post 9 and the positioning groove 11 and the cooperation of the elastic buckle 8 and the clamping groove 10. The movement of the louver link 3 can synchronously drive a plurality of louvers 2 to achieve synchronous rotation on the louver bracket 1, realizing the adjustment of the air outlet direction.

[0024] In order to further improve the convenience of installation and disassembly and the stability of the connection structure, there are two of the above-mentioned elastic buckles 8 and the above-mentioned clamping grooves 10, which correspond to each other one by one. The positioning post 9 is arranged between the two elastic buckles 8. The two elastic buckles 8 are symmetric based on the above-mentioned positioning. That is to say, during use, by simultaneously applying forces to the two elastic buckles 8, the elastic buckles 8 can be separated from the clamping grooves 10, ensuring the stability in the actual clamping state and facilitating the application of forces during disassembly. Further, a limiting block 12 for abutting against the edge of the clamping groove 10 is arranged at the end of the elastic buckle 8 to ensure the stability in the installation state.

[0025] The above-mentioned positioning post 9 can be a triangular prism, a quadrangular prism or a pentagonal prism to ensure that there is no relative sliding between the positioning post 9 and the positioning groove 11. Preferably, the above-mentioned positioning post 9 is a quadrangular prism. Through the limiting effects in two directions of the transverse limiting surface and the longitudinal limiting surface formed by the quadrangular prism, sufficient stability between the swing rod 6 and the swing leaf connecting rod 3 is ensured.

[0026] Due to the structure of synchronous series connection between the above-mentioned swing leaf connecting rod 3 and multiple swing leaves 2, a synchronous swinging effect is required, and an angular change may occur between the swing leaf 2 and the swing leaf connecting rod 3. To ensure the smoothness and stability of the driving action of the overall structure, both the swing leaf connecting rod 3 and the multiple swing leaves 2 are rotatably connected structures. Specifically, a connecting shaft 13 is arranged on the side of the swing leaf 2 close to the swing leaf connecting rod 3, and the swing leaf connecting rod 3 is provided with a connecting hole 15 that rotatably cooperates with the connecting shaft 13. The rotational connection effect is ensured through the rotational cooperation between the connecting shaft 13 and the connecting hole 15. In addition, in order to further improve the convenience of installation and disassembly between the swing leaf 2 and the swing rod 6 of the swing leaf 2, an elastic clip 14 is arranged on the swing leaf connecting rod 3. The inner side wall of the elastic clip 14 forms the above-mentioned connecting hole 15 with a single-sided opening. That is, by applying a force to the elastic clip, the single-sided opening of the connecting hole 15 is expanded so that the connecting shaft 13 can be snapped into the connecting hole 15 to achieve a stable rotating pair. Such a structure is convenient for disassembly and assembly, ensuring the convenience of subsequent maintenance and component replacement.

[0027] Specifically for the above-mentioned driving assembly 7, it includes a driving motor 71. The driving motor 71 is provided with a driving shaft 72. The driving shaft 72 is connected with a crank 73. The end of the crank 73 far from the driving motor 71 is rotatably connected to the swing rod 6. The entire driving assembly 7 cooperates with the swing rod 6 to form a stable crank 73 connecting rod mechanism, ensuring a stable reciprocating movement effect of the swing rod 6.

[0028] In summary, the present utility model provides an air conditioner swing blade linkage mechanism, which includes a swing blade bracket 1. A plurality of swing blades 2 are arranged at intervals in the length direction of the swing blade bracket 1. A rotating shaft 4 is provided on the swing blade 2, and the rotating shaft 4 is rotatably connected to the swing blade bracket 1. A swing blade connecting rod 3 is arranged on one side of the swing blade bracket 1. The swing blade connecting rod 3 sequentially connects a plurality of the swing blades 2 in series, and the swing blades 2 are rotatably connected to the swing blade connecting rod 3. A driving end 5 is provided on the swing blade connecting rod 3. An elastic buckle 8 and a positioning post 9 are provided at the driving end 5. A swing rod 6 is connected to the driving end 5. The swing rod 6 is provided with a clamping groove 10 and a positioning groove 11. The clamping groove 10 is in clamping fit with the elastic buckle 8. The positioning post 9 is adapted in shape to the positioning groove 11 and is in plug-in fit therewith. The positioning post 9 is in the shape of a polygonal prism. A driving assembly 7 for driving the swing rod 6 to move is connected to the side of the swing rod 6 away from the driving end 5. The connection between the swing blade connecting rod 3 and the swing rod 6 can be made more firm by the quadrangular prism-shaped limiting post in the whole structure. The two connecting parts will not rotate relative to the positioning post 9, and the connection is reliable. The disassembly operation is more convenient and can be removed by gently pinching. The connection is not easily detached by accidental touch. Even if a single clip is accidentally touched, it will not fall off and fail.
