Description

Technical Field

[0001] This utility model relates to the field of air conditioner blade technology, and in particular to an air conditioner blade synchronous transmission mechanism, mounting frame and air conditioner. Background Technology

[0002] Modern air conditioner indoor units typically have movable louvers (also known as air deflectors or dampers) installed at the air outlet. These are key components for achieving comfortable airflow. These thin plastic or metal blades function primarily to precisely control the horizontal or vertical direction of the airflow, optimizing indoor air distribution, preventing direct airflow onto people, and improving overall comfort. To achieve diverse airflow modes (such as upward blowing, downward blowing, sweeping, and fixed-angle airflow), the louvers need to have flexible angle adjustment capabilities, which rely on the power provided by the motor.

[0003] Traditional oscillating blade structures achieve basic air guiding functions through mechanical linkage, with each oscillating blade corresponding to an independent motor. However, since multiple oscillating blades are controlled by multiple independent motors, not only does the number of motors increase, but independent synchronization control algorithms are also required to ensure the linkage accuracy of the oscillating blades, indirectly increasing production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a synchronous transmission mechanism for air conditioner blades, a mounting frame, and an air conditioner, which solves the problem of high production costs caused by multiple motors controlling the rotation of different blades in existing technologies.

[0005] According to an embodiment of the present invention, an air conditioner louver synchronous transmission mechanism includes a mounting housing. Inside the mounting housing, a drive gear, a transmission gear, and a driven gear are rotatably arranged via a rotating shaft. The transmission gear is located between the drive gear and the driven gear. The drive gear and the driven gear mesh with the two sides of the transmission gear, respectively. A motor for driving the drive gear is provided on the outer wall of the mounting housing. One end of the rotating shaft containing the drive gear and the driven gear extends out of the mounting housing and is detachably provided with louvers.

[0006] Compared with the prior art, this utility model has the following advantages: by setting a driving gear, a transmission gear, and a driven gear inside the mounting housing, and having one end of the shaft containing the driving gear and the driven gear protrude from the mounting housing and has a swing blade, since the two sides of the transmission gear mesh with the driving gear and the driven gear respectively, when the motor drives the driving gear to rotate, the transmission gear and the driven gear follow it to rotate, thereby making the two swing blades rotate synchronously, achieving the effect of adjusting the airflow direction of the air outlet. By using the same motor to drive the movement of the driving gear and the driven gear, the two swing blades are driven to swing synchronously, saving production costs.

[0007] Furthermore, the mounting housing includes an upper housing and a lower housing, with a retaining ring on the upper housing and a retaining block on the lower housing that engages with the retaining ring.

[0008] Furthermore, it also includes a pin, a retaining plate at one end of the shaft where the drive gear and driven gear are located extending out of the mounting housing, a mounting block on the side wall of each blade, a slot for inserting the retaining plate on the mounting block, and a slot at one end of the retaining plate extending out of the slot for the pin to engage.

[0009] Furthermore, each blade has a first wedge-shaped portion on one side and a second wedge-shaped portion that cooperates with the first wedge-shaped portion on the other side.

[0010] On the other hand, according to an embodiment of the present invention, an air conditioner louver mounting frame is also provided, including the aforementioned air conditioner louver synchronous transmission mechanism, and also including a frame body. A ventilation groove for accommodating the louver is provided on the outer side of the frame body, and a plurality of hollow grooves communicating with the inner side of the frame body are provided in the ventilation groove. A mounting platform is provided on the inner side of the frame body, and a mounting groove for accommodating the mounting shell is provided on the mounting platform.

[0011] Furthermore, several reinforcing ribs are provided on the outer wall of the mounting platform.

[0012] Furthermore, there is a gap between the mounting slot and the mounting shell.

[0013] Furthermore, a limit hook is provided on the outer wall of the mounting platform.

[0014] On the other hand, an air conditioner is also provided according to an embodiment of the present invention, including the aforementioned air conditioner louver mounting frame. Attached Figure Description

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, this utility model embodiment proposes a synchronous transmission mechanism for air conditioner blades, including a mounting shell 1. Inside the mounting shell 1, a driving gear 3, a transmission gear 4, and a driven gear 5 are rotatably arranged via a rotating shaft 2. The transmission gear 4 is located between the driving gear 3 and the driven gear 5. The driving gear 3 and the driven gear 5 are respectively meshed with the two sides of the transmission gear 4. A motor 6 for driving the driving gear 3 to rotate is provided on the outer wall of the mounting shell 1. One end of the rotating shaft 2 where the driving gear 3 and the driven gear 5 are located passes through the mounting shell 1 and is detachably provided with blades 7. At least one synchronized transmission mechanism for the air conditioner's swivel blades is provided on each air conditioner. The output end of the motor 6 is connected to the rotating shaft 2 where the drive gear 3 is located. The motor 6 drives the drive gear 3 to rotate, which in turn drives the transmission gear 4 to rotate. The transmission gear 4 then drives the driven gear 5 to rotate. Due to the presence of the transmission gear 4, the drive gear 3 and the driven gear 5 are in the same direction, so that when the drive gear 3 and the driven gear 5 rotate, they simultaneously drive the two swivel blades 7 to rotate synchronously. This achieves the opening and closing of the air conditioner's air outlet and changes its airflow direction. This device achieves the synchronous oscillation of two swivel blades 7 through the same motor 6, saving costs and eliminating the need for an additional synchronous control algorithm system, thus saving manufacturing costs. In a preferred embodiment, the size of the swivel blades 7 can be controlled so that the two swivel blades 7 can cover the entire air outlet of the air conditioner.

[0024] like Figures 5 to 6 As shown, the mounting housing 1 further includes an upper housing 101 and a lower housing 102. The upper housing 101 is provided with a retaining ring 103, and the lower housing 102 is provided with a retaining block 104 that cooperates with the retaining ring 103. Both the upper housing 101 and the lower housing 102 are provided with chambers for accommodating components such as the driving gear 3 and the driven gear 5. The upper housing 101 and the lower housing 102 of the mounting housing 1 are connected by the retaining ring 103 and the retaining block 104, which facilitates the disassembly of the upper housing 101 and the lower housing 102. During maintenance, the mounting housing 1 can be quickly opened to perform maintenance work on the internal components such as the driving gear 3 and the driven gear 5.

[0025] likeFigure 5 As shown, further, it also includes a pin 8, a retaining plate 9 at one end of the shaft 2 where the driving gear 3 and driven gear 5 are located, extending out of the mounting housing 1, and a mounting block 10 on the side wall of each blade 7. The mounting block 10 has a slot for inserting the retaining plate 9, and the end of the retaining plate 9 that extends out of the slot has a slot for the pin 8 to engage. The retaining plate 9 is connected to the mounting block 10 by the pin 8, which enables the blade 7 to be detachably installed, making subsequent maintenance and cleaning of the blade 7 more convenient.

[0026] like Figure 6 As shown, further, each oscillating blade 7 has a first wedge-shaped portion 11 on one side and a second wedge-shaped portion 12 that cooperates with the first wedge-shaped portion 11 on the other side. Specifically, the first wedge-shaped portion 11 has a notch on one side of the oscillating blade away from the motor 6, and the second wedge-shaped portion 12 has a notch on the side closer to the motor 6, so that the first wedge-shaped portion 11 and the second wedge-shaped portion 12 can cover each other. The oscillating blades 7 are mass-produced, and after two oscillating blades 7 are installed, the first wedge-shaped portion 11 of one oscillating blade 7 is inserted under the second wedge-shaped portion 12 of the other oscillating blade 7. Through the cooperation of the first wedge-shaped portion 11 and the second wedge-shaped portion 12, the air outlet of the air conditioner is sealed more completely while ensuring that the two oscillating blades 7 have sufficient swing space.

[0027] like Figures 1 to 2 As shown, on the other hand, according to an embodiment of the present invention, an air conditioner louver mounting frame is also provided, including the aforementioned air conditioner louver 7 synchronous transmission mechanism, and also including a frame body 13. A ventilation groove for accommodating the louver 7 is provided on the outer side of the frame body 13. Several hollow grooves communicating with the inner side of the frame body 13 are provided in the ventilation groove. A mounting platform 14 is provided on the inner side of the frame body 13, and a mounting groove 15 for accommodating the mounting shell 1 is provided on the mounting platform 14. In this embodiment, the mounting shell 1 is disposed in the ventilation groove of the mounting platform 14, and the hollow groove on the frame body 13 is the air outlet. The two louvers 7 are rotatably disposed in the ventilation groove to control the opening and closing of the air outlet. The frame body 13 is concave in shape, with a ventilation groove and a corresponding air conditioner louver 7 synchronous mechanism installed on each of its two wings. Through the action of the air conditioner louver 7 synchronous transmission mechanism, the louvers 7 swing to a predetermined angle, causing the airflow from the air conditioner to blow in a predetermined direction, improving user comfort.

[0028] like Figure 3 As shown, furthermore, a number of reinforcing ribs 16 are provided on the outer wall of the mounting platform 14. Since the mounting platform 14 is located inside the face frame body 13, and the corresponding position on the outer side of the face frame body 13 is a ventilation slot, part of the mounting platform 14 is a thin shell structure, and the reinforcing ribs 16 can improve the overall strength of the mounting platform 14.

[0029] like Figure 4As shown, there is a gap between the mounting groove 15 and the mounting shell 1. The mounting shell 1 is mostly made of plastic material. While ensuring that other components of the air conditioner have installation space, the gap between the mounting groove 15 and the mounting shell 1 provides space for the deformation of the mounting shell 1 after being heated, and can also play a certain role in vibration isolation.

[0030] like Figure 3 and Figure 4 As shown, a limiting hook 17 is further provided on the outer wall of the mounting platform 14. The limiting hook 17 facilitates the storage of power cords for components such as the motor 6, keeps the interior of the air conditioner tidy, and facilitates later maintenance and inspection.

[0031] On the other hand, an embodiment of this utility model also provides an air conditioner, including the aforementioned air conditioner blade mounting frame. This device controls the synchronous rotation of two blades 7 by a motor 6, saving on the cost of manufacturing the air conditioner while ensuring the required airflow direction adjustment function is achieved.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
