Technical Field
[0001] This utility model relates to the field of ceiling fan technology, and in particular to a ceiling fan oscillation mechanism based on a hinged support frame. Background Technology
[0002] Ceiling fans are a common type of ventilation and cooling device, widely used in various spaces such as homes, offices, and shopping malls. The oscillation function is one of the important features of ceiling fans, which changes the direction of airflow to achieve a wider range of air circulation and improve user comfort.
[0003] Existing ceiling fan oscillation mechanisms have some shortcomings in use. The oscillation angle adjustment is not flexible enough, and most mechanisms can only achieve a fixed angle of reciprocating oscillation, making it difficult to accurately adjust the air delivery range according to actual usage needs. Therefore, a ceiling fan oscillation mechanism based on a hinged support frame is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a ceiling fan oscillation mechanism based on a hinged support frame to solve the problems mentioned in the background art.
[0005] To solve the above problems, the following technical solution is provided: a ceiling fan oscillation mechanism based on a hinged support frame, including a ceiling mounting base, a limiting frame fixedly mounted on the front side of the ceiling mounting base and a limiting plate fixedly mounted on one end of the limiting frame, a first hinge frame rotatably mounted on the upper end of the limiting frame, a dual-axis motor fixedly mounted inside the first hinge frame, connecting rods fixedly mounted on both ends of the dual-axis motor and a worm gear fixedly connected to one end of one of the connecting rods, a worm wheel meshing with the outer wall of the worm gear, a main gear arranged below the worm wheel, a driven gear meshing with the outer wall of the main gear, the driven gear rotatably mounted inside a second hinge frame, an angle adjustment plate fixedly mounted on the bottom of the second hinge frame, the bottom of the angle adjustment plate rotatably connected to a collar and a guide frame fixedly connected to the outer wall of the collar.
[0006] As a preferred embodiment of the above technical solution, the two connecting rods are respectively rotatably installed inside the hinge limiting frame on both sides of the first hinge frame, and one end of one of the connecting rods is fixedly connected to the fan body.
[0007] As a preferred embodiment of the above technical solution, one end of the worm gear is rotatably mounted on the outer wall of the hinged limiting frame, a limiting post is fixedly mounted in the middle of the worm wheel, and the limiting post is fixedly connected to the main gear.
[0008] As a preferred embodiment of the above technical solution, the limiting post is rotatably installed inside the second hinge frame, the main gear and the driven gear are matched in position, the worm and the worm wheel are matched in position, and a connecting block is fixedly installed at one end of the guide frame, and the connecting block is rotatably installed inside the limiting plate.
[0009] As a preferred embodiment of the above technical solution, the ceiling mounting base has two sets of adjustment grooves inside, and a locking rod runs through both sets of adjustment grooves. A limit cap is fixedly connected to one end of the locking rod.
[0010] As a preferred embodiment of the above technical solution, a mounting shim is inserted inside the locking rod, the mounting shim and the adjustment groove are in contact, and a shock-absorbing pad is fixedly connected to the inner wall of the ceiling mounting base.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model device includes a dual-axis motor, worm gear, worm wheel, main gear, driven gear, angle adjustment plate, guide frame, and other components. The worm gear is driven to rotate on the first hinge frame by a connecting rod at one end of the dual-axis motor. This causes the worm gear to rotate on the second hinge frame, which in turn drives the main gear to rotate via a limiting post. The main gear then drives the driven gear to rotate, which in turn drives a collar on the angle adjustment plate. This collar causes a connecting block on the guide frame to rotate and be limited within the limiting plate. The hinge support frame enables the horizontal oscillation and pitch angle adjustment of the fan. Using a gear meshing drive method, compared to the traditional multi-link structure, the number of parts is significantly reduced, the structure is simpler, the assembly process is simplified, and the manufacturing cost is lowered.
[0013] 2. This utility model device is equipped with shock-absorbing pads, locking rods, mounting shims, and limit caps. By adjusting the four locking rods to move within the adjustment grooves, the movement stops when the locking rods are aligned with the top position. Then, the locking rods and mounting shims on the limit caps are tightened using a tool. This facilitates the adjustment and installation of the locking rod positions according to the top dimensions, improving the flexibility and fixation of the ceiling mounting base.

It should be understood that the embodiments of the present invention are not limited in scope.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figures 1 to 4 As shown, this embodiment provides a ceiling fan oscillation mechanism based on a hinged support frame, including a ceiling mounting base 1. A limit frame is fixedly installed on the front side of the ceiling mounting base 1, and a limit plate 12 is fixedly installed on one end of the limit frame. A first hinge frame 6 is rotatably installed on the upper end of the limit frame. A dual-axis motor 3 is fixedly installed inside the first hinge frame 6. Connecting rods 8 are fixedly installed on both ends of the dual-axis motor 3, and a worm gear 5 is fixedly connected to one end of one of the connecting rods 8. A worm wheel 9 is meshed with the outer wall of the worm gear 5. A main gear 10 is provided below the worm wheel 9. A driven gear 13 is meshed with the outer wall of the main gear 10. The driven gear 13 is rotatably installed inside a second hinge frame 11. An angle adjustment plate 14 is fixedly installed at the bottom of the second hinge frame 11. The bottom of the angle adjustment plate 14 is rotatably connected to a collar 15, and a guide frame 16 is fixedly connected to the outer wall of the collar 15.
[0023] like Figures 2 to 3As shown, two connecting rods 8 are rotatably installed inside the hinge limit frames 7 on both sides of the first hinge frame 6. One end of one connecting rod 8 is fixedly connected to the fan body 4, and one end of the worm gear 5 is rotatably installed on the outer wall of the hinge limit frame 7. A limit post 91 is fixedly installed in the middle of the worm wheel 9. The limit post 91 is fixedly connected to the main gear 10. The limit post 91 is rotatably installed inside the second hinge frame 11. The main gear 10 and the driven gear 13 are matched in position. The worm gear 5 and the worm wheel 9 are matched in position. A connecting block 17 is fixedly installed at one end of the guide frame 16, and the connecting block 17 is rotatably installed inside the limit plate 12.
[0024] By rotating and limiting the worm 5 within the hinge limit frame 7 on the first hinge frame 6, the meshing position of the worm 5 and the worm wheel 9 is made relatively accurate. At the same time, when the worm wheel 9 rotates, it drives the main gear 10 to mesh with the driven gear 13 and rotate, so that the driven gear 13 drives the second hinge frame 11 to rotate as a whole, thereby driving the guide frame 16 on the bottom angle adjustment plate 14 to rotate and limit its position.
[0025] like Figure 4 As shown, the ceiling mounting base 1 has two sets of adjustment grooves 23 inside, and the locking rod 22 passes through both sets of adjustment grooves 23. One end of the locking rod 22 is fixedly connected to the limit cap 2, and the locking rod 22 is inserted with the mounting pad 21. The mounting pad 21 and the adjustment groove 23 are in close contact. The inner wall of the ceiling mounting base 1 is fixedly connected with the shock-absorbing pad 18.
[0026] The shock-absorbing pad 18 is made of rubber and has a honeycomb structure inside, which can effectively absorb the vibration generated during the operation of the dual-axis motor 3 and prevent the vibration from being transmitted to the ceiling mounting base 1 and the ceiling structure, thereby reducing noise. At the same time, multiple adjustment slots 23 are opened in the ceiling mounting base 1 to facilitate the adjustment and installation of the locking rod 22 according to the installation size and position of the top, thereby enabling multi-range installation of the ceiling mounting base 1.
[0027] The working principle and process of this utility model are as follows: First, align the ceiling mounting base 1 with the top. Then, according to the position and dimensions of the top, adjust the four locking rods 22 within the adjusting grooves 23. Stop moving when the locking rods 22 are aligned with the top. Then, use a tool to tighten the locking rods 22 and the mounting washers 21 on the limit caps 2. This facilitates the adjustment and installation of the locking rods 22 according to the top dimensions. When the fan needs to be turned on, the fan is driven to rotate by the front connecting rod 8 of the dual-axis motor 3. When the fan needs to rotate, the connecting rod 8 at one end of the dual-axis motor 3 drives the worm gear 5 to rotate on the first hinge frame 6, which in turn drives the worm wheel 9 to rotate on the second hinge frame 11. The worm wheel 9 then drives the main gear 10 to rotate via the limiting post 91, which in turn drives the driven gear 13 to rotate. The driven gear 13 then drives the collar 15 on the angle adjustment plate 14 to rotate, which in turn drives the connecting block 17 on the guide frame 16 to rotate and limit its position within the limiting plate 12. This allows the fan to rotate and oscillate at multiple positions and angles.
