Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a transmission structure, oscillation device, and tower fan for an oscillating motor. Background Technology

[0002] Tower fans, due to their small size, gentle airflow, and safety, are a preferred choice for homes with elderly people and children. Compared to ordinary fans, they offer both cooling and heating modes. This combination of functions means that the oscillation component is primarily located at the bottom of the tower fan body, with a claw-pole permanent magnet synchronous motor ensuring the rotation of the entire unit. Chinese patent CN109404326A discloses an oscillation device and tower fan, which solves the problem of the internal motor flipping due to impacts or other external forces when the oscillation reaches its limit angle. However, its structure for implementing oscillation and oscillation limit functions is relatively complex, requiring many components for these functions, thus reducing the overall error of the oscillation transmission and resulting in higher component costs. Currently, the transmission structure of the component is prone to motor end cap warping under excessive external torsion, causing the entire unit to fail to power on or oscillate. Therefore, to prevent such malfunctions during children's play or adults' handling, and to eliminate these hidden dangers and ensure the normal operation and lifespan of the rotating parts, the transmission structure of the oscillation tower fan must be improved. Summary of the Invention

[0003] To address the problem of uneven force on the motor and end cover warping caused by violent and prolonged operation of the oscillating motor, this invention provides a transmission structure, oscillating device, and tower fan for an oscillating motor. Structurally, it improves the phenomenon of excessive torsion causing the bottom shell of the oscillating motor to warp and fall off, and can effectively avoid the problem of excessive torsion of the oscillating motor and tower fan under external force.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a transmission structure for a oscillating motor, comprising a base, a bracket mounted on the base and rotating around an axis, and an oscillating motor fixed on the bracket. The bracket is provided with a support column for fixing the oscillating motor. Below the oscillating motor, there is also a support frame. The support frame has a support top plate for supporting the end cover of the oscillating motor and multiple support vertical plates. The support vertical plates and the support column are abutted by a first reinforcing rib so that the support vertical plates, the support column, and the first reinforcing rib form an integral support and reinforcement structure. The top surface of the support top plate is flush with the top surface of the support column, so that the oscillating motor is locked to the top surface of the support column through mounting holes and screws, and the bottom surface of the end cover of the oscillating motor abuts against the support top plate.

[0005] Preferably, the bracket has an arc-shaped through slot corresponding to the fixed column on the base so that the fixed column passes through the bracket and connects to the linkage of the oscillating motor, and the fixed column has a second reinforcing rib on the side of the linkage in the direction of movement.

[0006] Preferably, the linkage assembly has a first link connecting the output shaft of the oscillating motor and a second link connecting the first link. One end of the second link is hinged to the fixed column. When the oscillating motor drives the first link to rotate around the output end, the oscillating motor and the bracket rotate around the axis through the hinge between the second link and the first link.

[0007] Preferably, a limiting protrusion is provided near the end of the through groove, and the second connecting rod extends from one end near the fixed post toward the limiting protrusion with a limiting protrusion. The oscillating motor drives the linkage group to rotate the through groove. When it is at the limit angle stroke, the limiting protrusion blocks the limiting protrusion so that the rotation stroke of the bracket does not exceed the set maximum oscillating path.

[0008] Preferably, the limiting protrusion extends into the through groove with a first limiting protrusion, and the through groove is provided with a second limiting protrusion on the opposite side of the limiting protrusion. The distance between the first limiting protrusion and the second limiting protrusion is slightly greater than the width of the end of the second connecting rod so that when the second connecting rod runs to the limit angle travel limit, the second connecting rod is further limited in the horizontal direction.

[0009] Preferably, one side of the supporting top plate is fixed to the top of the supporting vertical plate and is flush with the top surface of the supporting vertical plate. The supporting vertical plate is connected to the first supporting column near the center by a first reinforcing rib to enhance the overall supporting strength.

[0010] Preferably, the outer edge of the oscillating motor has mounting holes corresponding to the first support column and the second support column away from the center, which are locked with screws. The top support plate has an anti-interference notch corresponding to the output shaft of the oscillating motor. The thickness of the top support plate is less than the distance between the first connecting rod and the bottom surface of the end cover of the oscillating motor.

[0011] Preferably, the overall support reinforcement structure has a hollow area at the bottom of the support top plate to prevent interference with the rotation of the first connecting rod around the output shaft.

[0012] On the other hand, the present invention provides the following technical solution: a swaying device, including the transmission structure of the swaying motor described above.

[0013] On the other hand, the present invention provides the following technical solution: a tower fan, including the above-mentioned transmission structure of an oscillating motor, wherein the oscillating motor drives the bracket to rotate around the axis through a linkage group to make the tower fan component assembled or transmitted on the bracket oscillate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the linkage of the oscillating motor is twisted to the limit by external force, the limiting effect prevents the tower fan from easily twisting beyond the maximum oscillation angle, effectively avoiding irreversible damage caused by external force. This invention effectively avoids excessive twisting of the oscillating motor transmission structure and tower fan under external force, prevents uneven force on the oscillating motor and end cover warping under violent and prolonged operation, avoids the safety risk of power failure due to the bottom shell warping of the oscillating motor, and increases the service life and operational stability of the oscillating motor transmission, the oscillating device using this transmission structure, and the tower fan.

[0016] Compared to existing technologies that forcibly twist tower fans to oscillate, where insufficient structural restraints can cause the oscillation motor end cap to detach under stress when the forced rotation angle exceeds the maximum oscillation angle, this embodiment addresses this issue by adding reinforcing ribs and restraining structures to the base's fixing column and the support column of the bracket. This prevents the fixing column or support column from breaking under violent twisting, thus avoiding the tower fan rotating beyond its rotation range. Simultaneously, a support top plate is added to the bracket to support the oscillation motor's end cap, preventing it from detaching under external torsion. Furthermore, the support top plate, support vertical plate, and support column are integrated into a single reinforced support structure through reinforcing ribs, effectively improving the overall mechanical strength and stability of the bracket.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0026] like Figure 1 and Figure 2 As shown, a transmission structure for a oscillating motor includes a base 100, a bracket 200 mounted on the base 100 and rotating around an axis, and an oscillating motor (not shown) fixed on the bracket 200. The bracket 200 is provided with support columns for fixing the oscillating motor. The support columns include a first support column 210 near the center and a second support column 220 away from the center. The outer edge of the oscillating motor is provided with mounting holes corresponding to the first support column 210 and the second support column 220. The oscillating motor is fixed to the first support column 210 and the second support column 220 with screws through the mounting holes.

[0027] Below the oscillating motor is a support frame, which has a top support plate 230 for supporting the end cover of the oscillating motor and multiple vertical support plates 240. The vertical support plates 240 and the support column 210 are connected by a first reinforcing rib 250 so that the vertical support plates 240, the support column 210 and the first reinforcing rib 250 form an integral support and reinforcement structure. The vertical support plates 240 and the first support column 210 near the center are connected by a first reinforcing rib to enhance the overall support strength.

[0028] The top support plate 230 is fixed horizontally to the top of the vertical support plate 240 and is flush with the top surface of the vertical support plate 240. The top surface of the top support plate 230 is flush with the top surface of the support column, so that the bottom surface of the end cover of the oscillating motor abuts against the top support plate, which increases the stability of the oscillating motor assembly, can effectively support the end cover of the oscillating motor, reduce the impact of external forces on the oscillating motor, and also prevent the end cover of the oscillating motor from coming off after being subjected to force.

[0029] The bracket 200 has an arc-shaped through slot 260 corresponding to the fixed column 110 on the base 100 so that the fixed column 110 passes through the bracket 200 and connects to the linkage of the oscillating motor. The fixed column 110 has a second reinforcing rib 120 on the side of the linkage in the direction of movement. The second reinforcing rib is arranged in the direction of force exerted by the linkage on the fixed column, which effectively enhances the mechanical strength and support of the fixed column and prevents the fixed column from breaking backward under strong external force.

[0030] The linkage assembly has a first link 310 connecting the output shaft 300 of the oscillating motor and a second link 320 connecting the first link 310. One end of the second link 320 is hinged to the fixed column 110. When the oscillating motor drives the first link 310 to rotate around the output end 300, the oscillating motor and the bracket 200 rotate around the axis through the hinge between the second link 320 and the first link 310. That is, the bracket 200 rotates on the fixed base 100.

[0031] The supporting top plate 230 is provided with an anti-interference notch 231 corresponding to the output shaft of the oscillating motor. The thickness of the supporting top plate 230 is less than the distance between the first connecting rod and the bottom surface of the end cover of the oscillating motor. The overall support reinforcement structure is provided with a hollow area at the bottom of the supporting top plate 230 to prevent interference with the rotation of the first connecting rod 310 around the output shaft 300. This ensures that the supporting top plate supporting the oscillating motor does not affect the operation of the linkage group, and there is no interference at the support part, thus meeting the assembly clearance requirements.

[0032] The through slot 260 is provided with a limiting protrusion 261 near its end. The second connecting rod 320 extends from one end near the fixed column 110 toward the limiting protrusion 261, protruding with a limiting protrusion 321. The oscillating motor drives the linkage group to make the through slot 260 rotate around the center of the base. When it is at the limit angle stroke, that is, the maximum oscillation angle, the limiting protrusion 321 blocks the limiting protrusion 261 to prevent the bracket 200 from rotating, and the rotation stroke does not exceed the set maximum oscillation path. When subjected to external force, the limiting protrusion can prevent the bracket from rotating beyond the limit angle, thus minimizing the risk of the oscillating motor overturning and improving the reliability and safety of the oscillation transmission, oscillation device, and tower fan.

[0033] The limiting protrusion 261 extends into the through groove 260 with a first limiting protrusion 262. The through groove 260, corresponding to the limiting protrusion 261 on the opposite side, has a second limiting protrusion 263. The distance between the first limiting protrusion 262 and the second limiting protrusion 263 is slightly larger than the width of the end of the second connecting rod 320. This distance is designed to allow the end of the second connecting rod to easily enter the area between them without interfering with its normal movement trajectory. A slight increase of 0.1-0.2 cm further limits the horizontal movement of the second connecting rod when it reaches its maximum yaw angle, preventing unexpected situations such as overturning of the linkage assembly under external force. The second protrusion also strengthens the mechanical and supporting strength of the sidewall used to assemble the central shaft of the bracket.

[0034] In this implementation case, when the linkage assembly of the oscillating motor is twisted to the limit by external force, the limiting effect will prevent the tower fan from easily twisting beyond the maximum oscillation angle, effectively avoiding irreversible damage caused by external force. It can effectively prevent the oscillating motor transmission structure and tower fan from excessive twisting under external force, avoid uneven force on the oscillating motor and end cover warping under violent and long-term operation, avoid the safety risk of power failure due to the oscillating motor bottom shell warping, and increase the service life and operational stability of the oscillating motor transmission, the oscillating device using this transmission structure, and the tower fan.

[0035] On the other hand, this embodiment also provides the following technical solution: a swaying device, including the transmission structure of the swaying motor described above.

[0036] On the other hand, this embodiment also provides the following technical solution: a tower fan, including the aforementioned transmission structure of an oscillating motor, wherein the oscillating motor drives a bracket to rotate around an axis via a linkage group, causing the tower fan component assembled or transmitted to the bracket to oscillate. The transmission structure of the oscillating motor enhances the limiting and supporting function of the oscillation function, improves the phenomenon of excessive torsion causing the motor base to warp and detach, increases the service life of the tower fan, and improves its safety and stability.

[0037] In existing technologies, when tower fans are forcibly twisted to oscillate (e.g., during play or transport, causing strong external forces to rotate the fan), if the forced rotation angle exceeds the maximum oscillation angle, insufficient structural restraint can cause the oscillation motor end cap to detach under stress. Therefore, this embodiment addresses this issue by adding reinforcing ribs and restraining structures to the base's fixing column and the bracket's support column. This prevents the screw column (fixing or support column) from breaking under violent twisting, thus avoiding the tower fan rotating beyond its rotation range. Simultaneously, a support top plate is added to the bracket to support the oscillation motor's end cap, preventing it from detaching under external torsion. Furthermore, the support top plate, support vertical plate, and support column are integrated into a single reinforced support structure through reinforcing ribs, effectively improving the overall mechanical strength and stability of the bracket.

[0038] The above disclosures are merely one or more preferred embodiments of the present invention, intended to help understand the inventive concept of the technical solution, and are not intended to limit the present invention in any other way. Any other equivalent or conventional substitution schemes made by those skilled in the art based on the features defined by the present invention shall still fall within the scope of the present invention.
