Description

Technical Field

[0001] This utility model relates to the field of air blowing equipment technology, and in particular to an oscillating fan. Background Technology

[0002] Oscillating fans typically have a rotating mechanism connected to the fan assembly. This mechanism drives the fan assembly to rotate, allowing the oscillating fan to blow air at multiple angles, effectively increasing its airflow range.

[0003] Existing rotating mechanisms typically require a high-power motor to provide sufficient steering force to the heavy fan assembly, enabling it to rotate stably in the vertical direction and achieve the wide-angle blowing effect of an oscillating fan. However, using a high-power motor tends to result in a larger overall structural size of the rotating mechanism, occupying more space and hindering the miniaturization design of oscillating fans. Utility Model Content

[0004] The main purpose of this invention is to propose an oscillating fan, which aims to improve the structural design of the rotating mechanism, reduce the overall structural size of the rotating mechanism, and achieve a better miniaturization design for the oscillating fan.

[0005] To achieve the above objectives, the present invention proposes an oscillating fan comprising a support structure, a fan assembly, and a rotating mechanism. The fan assembly includes a fan body and fan blades, with the fan body driving the fan blades to rotate. The rotating mechanism includes a first connecting member, a second connecting member, a driving device, and a spring assembly. The first connecting member is connected to the support structure, and a first rib is provided on the side of the first connecting member facing away from the support structure. The second connecting member is connected to the fan assembly, and a second rib is provided on the side of the second connecting member facing away from the fan assembly. The plane of the second rib is parallel to or coincides with the plane of the first rib. The driving device connects the first rib and the second rib and drives the second connecting member to rotate relative to the first connecting member, so that the second connecting member drives the fan assembly to oscillate in the up-down direction. The spring assembly includes a compression spring, a first support member, and a second support member. The two ends of the compression spring are respectively connected to or abut against the first support member and the second support member. The first support member is rotatably connected to the first connecting member, and the second support member is rotatably connected to the second connecting member.

[0006] The first rib has a groove on the side facing the second connector, and the groove is arc-shaped. The first support has an arc-shaped protrusion on the side facing away from the compression spring. The arc-shaped protrusion is rotatably disposed in the groove and abuts against the inner wall of the groove.

[0007] In one embodiment, the second connector includes a base plate, the second rib is bent and connected to the side wall of the base plate, and the fan body is connected to the base plate.

[0008] In one embodiment, the second rib is provided with at least two wiring holes, and the oscillating fan further includes a transmission cable, which is arranged to pass through at least two of the wiring holes in sequence; the base plate is provided with a cable passage hole communicating with the fan assembly, and the transmission cable passes through the cable passage hole and is electrically connected to the fan body.

[0009] In one embodiment, the second rib has a cable guide groove on the side facing away from the base plate. The cable guide groove is located between two adjacent cable routing holes and communicates with the two cable routing holes. The transmission cable passes through the cable guide groove. The second rib also has a cable baffle plate on the side facing away from the base plate. The cable baffle plate is exposed in the slot of the cable guide groove and is used to limit the transmission cable.

[0010] In one embodiment, the support structure includes a support frame and a slewing mechanism. The slewing mechanism connects the first connector and the support frame and is used to drive the rotation mechanism to rotate horizontally relative to the support frame.

[0011] In one embodiment, the lateral rotation mechanism includes a first column, a second column, and a steering motor. The first column is connected to the support frame. The second column is stacked on top of the first column, and the end of the second column facing away from the first column is connected to the first connector. The steering motor connects the first column and the second column and drives the second column to rotate relative to the first column. Alternatively, the lateral rotation mechanism has a power connector on its periphery, and the oscillating fan further includes a transmission cable electrically connected to the power connector and passing through the lateral rotation mechanism and the rotation mechanism.

[0012] In one embodiment, the first rib has a groove on the side facing the second connector, the groove being arc-shaped, and the first support has an arc-shaped protrusion on the side facing away from the compression spring, the arc-shaped protrusion being rotatably disposed in the groove and abutting against the inner wall of the groove.

[0013] In one embodiment, the first support member includes a base plate and a support rod. The arc-shaped protrusion and the support rod are respectively connected to two opposite surfaces of the base plate. The compression spring is sleeved on the outer periphery of the support rod and spaced apart from the outer periphery of the support rod. One end of the compression spring is connected to or abuts against the base plate. The second support member is provided with a clearance hole, through which the support rod is movably disposed.

[0014] In one embodiment, in a direction perpendicular to the plane of the second rib, the second support member has connecting shafts on opposite sides; the second rib has a receiving space, and the second rib has connecting holes on two opposite inner walls of the receiving space; at least a portion of the structure of the second support member is rotatably disposed within the receiving space, and the two connecting shafts are rotatably inserted into the two connecting holes. And / or, the first rib has one of a limiting block or a limiting groove, and the second rib has the other of a limiting block or a limiting groove; the limiting groove extends along the rotation direction of the second connector, and the limiting block is disposed within the limiting groove and abuts against the two opposite inner walls of the limiting groove for limiting. And / or, the first connector has two first ribs, which are spaced apart and opposite to each other; the second connector has two second ribs, which are spaced apart and opposite to each other; each second rib cooperates with one first rib.

[0015] In one embodiment, the driving device includes a rotating shaft assembly and a drive motor. The rotating shaft assembly passes through and connects the first rib and the second rib. The drive motor is connected to the first rib and / or the second rib and drives the second connecting member to rotate relative to the first connecting member.

[0016] In one embodiment, the drive motor is mounted on the first rib, and the rotating shaft of the drive motor is connected to a drive wheel. A transmission rack is provided on the surface of the second rib facing the first rib, and the transmission rack extends along the rotation direction of the second connecting member. The drive wheel meshes with the transmission rack. Alternatively, the rotating shaft assembly includes a bushing, a shaft body, and a bearing. The bushing is disposed between the first rib and the second rib, connecting the first rib and / or the second rib. The bushing has a fixing groove, and the bearing is fixedly disposed within the fixing groove. The shaft body passes through the first rib, the bushing, and the second rib, and the bearing is sleeved on the outer periphery of the shaft body.

[0017] The technical solution of this utility model utilizes an elastic component to connect the first and second connecting parts. This allows the rotating mechanism to use the elastic force of the compression spring to assist the rotation of the second connecting part, thus reducing the output power requirement of the drive device. During the downward swing of the fan assembly towards the support structure, the weight of the fan assembly and the second connecting part acts on the compression spring, causing it to undergo elastic compression deformation and store elastic potential energy. Then, when the drive device drives the second connecting part to rotate upward relative to the first connecting part, the compression spring recovers its elastic deformation and applies a certain elastic force to the second connecting part. This elastic force is opposite to the direction of the second connecting part, thus offsetting part of the weight of the second connecting part and the fan assembly. This further reduces the power output required for the drive device to drive the second connecting part and the fan assembly to swing upward, allowing the drive device to use a lower-powered power source. This effectively reduces the overall size of the rotating mechanism, achieving a more compact design for the oscillating fan and improving its practicality and structural reliability.

[0038] Oscillating fans typically incorporate a rotating mechanism connected to a fan assembly. This mechanism drives the fan assembly to rotate, allowing the fan to blow air at multiple angles and effectively increasing its airflow range. Existing rotating mechanisms usually require a high-power motor to provide sufficient steering force to the heavy fan assembly, enabling stable vertical rotation and achieving the wide-angle airflow effect. However, using a high-power motor results in a larger overall size for the rotating mechanism, occupying more space and hindering the miniaturization of the oscillating fan design. To address these issues, this invention proposes an oscillating fan.

[0039] Please see Figures 1 to 3In one embodiment of this utility model, the oscillating fan 1000 includes a support structure 200, a fan assembly 400, and a rotating mechanism 100. The fan assembly 400 includes a fan body 41 and fan blades 43, with the fan body 41 driving the fan blades 43 to rotate. The rotating mechanism 100 includes a first connector 10, a second connector 30, a driving device 50, and a spring assembly 70. The first connector 10 is connected to the support structure 200, and a first rib 11 is provided on the side of the first connector 10 facing away from the support structure 200. The second connector 30 is connected to the fan assembly 400, and a first rib 11 is provided on the side of the second connector 30 facing away from the fan assembly 400. The second rib 31 has a plane that is parallel to or coincides with the plane of the first rib 11. The driving device 50 connects the first rib 11 and the second rib 31 and drives the second connecting member 30 to rotate relative to the first connecting member 10, so that the second connecting member 30 drives the fan assembly 400 to swing in the up and down direction. The elastic assembly 70 includes a compression spring 71, a first support member 73 and a second support member 75. The two ends of the compression spring 71 are connected to or abut against the first support member 73 and the second support member 75, respectively. The first support member 73 is rotatably connected to the first connecting member 10, and the second support member 75 is rotatably connected to the second connecting member 30.

[0040] In this application, the rotating mechanism 100 can install and connect the first connecting member 10 to the end of the support structure 200 such as the column or tripod, so as to achieve a stable connection between the rotating mechanism 100 and the support structure 200, and fix the fan assembly 400 to the second connecting member 30, thereby ensuring a stable support for the fan assembly 400.

[0041] The first rib 11 can refer to a plate-like structure disposed on the first connector 10, specifically made of metal stamping or bent sheet metal, etc., used to provide structural support and installation interface. The second rib 31 can refer to a corresponding plate-like structure disposed on the second connector 30, specifically made of metal stamping or bent sheet metal, etc., its planar arrangement ensures a stable relative motion trajectory with the first rib 11, ensuring the relative rotation of the first connector 10 and the second connector 30. The drive device 50 can refer to a power output unit, specifically made of a stepper motor with a reduction gear set, or a servo motor, etc. This application does not limit the specific structural form of the drive device 50, as long as it can achieve stable kinetic energy output. The compression spring 71 in the elastic component 70 can be a helical spring element, specifically made of carbon spring steel wire, which can store a certain amount of mechanical energy through elastic deformation and release the mechanical energy when restoring elastic deformation. The first support member 73 and the second support member 75 can respectively refer to load-bearing components with rotating joints, used to transmit the force of the compression spring 71 and allow rotational freedom, so that the compression spring 71 can stably extend and retract in a straight line when the first connecting member 10 and the second connecting member 30 rotate relative to each other, ensuring the supporting effect of the elastic component 70 on the second connecting member 30.

[0042] Specifically, when the drive device 50 drives the second connecting member 30 to rotate, the angle between the first connecting member 10 and the second connecting member 30 changes, and the change in the relative position between the two connecting members causes the elastic component 70 to deform. The rotational connection between the two supports ensures that the compression spring 71 can elastically compress or stretch along a straight line between the first connecting member 10 and the second connecting member 30, effectively preventing the compression spring 71 from bending during deformation and reducing the elastic force loss of the compression spring 71 during deformation, allowing the compression spring 71 to more fully absorb or release energy during compression or stretching. This energy conversion process effectively distributes the direct load of the drive device 50, allowing a smaller power drive motor 53 to be selected while maintaining the same rotational torque. Simultaneously, the parallel or overlapping arrangement of the two ribs ensures the stability of the rotation trajectory and avoids additional frictional losses caused by structural misalignment.

[0043] In this way, the driving device 50 can drive the second connecting member 30 to rotate closer to the first connecting member 10, so that when the angle between the first connecting member 10 and the second connecting member 30 decreases, the compression spring 71 will undergo a certain compression deformation under the action of the first connecting member 10 and the second connecting member 30, so that the compression spring 71 stores a certain amount of elastic mechanical energy. When the driving device 50 drives the second connecting member 30 to rotate away from the first connecting member 10, so that the angle between the first connecting member 10 and the second connecting member 30 increases, the compression spring 71 can be in a state of restoring elastic deformation. This is beneficial for the compression spring 71 to release the stored elastic mechanical energy onto the second connecting member 30, so that the compression spring 71 can apply a certain thrust to the second connecting member 30 in the direction away from the first connecting member 10. This is beneficial for the driving device 50 to output a lower driving power to the second connecting member 30. In other words, the driving device 50 can use a smaller power and smaller size driving motor 53 to ensure the stable operation of the rotating mechanism 100, and better meet the structural miniaturization design requirements of the rotating mechanism 100.

[0044] Furthermore, with the rotation mechanism 100 using the elastic component 70 to ensure the stable rotation of the second connecting member 30, the rotation mechanism 100 can stably drive the fan assembly 400 to swing and blow air in the up and down direction, so that the oscillating fan 1000 can achieve a larger air blowing range, making the oscillating fan 1000 better meet the user's needs and further improve the practicality and structural reliability of the oscillating fan 1000.

[0045] The technical solution of this utility model utilizes the elastic component 70 to connect the first connecting member 10 and the second connecting member 30. This allows the rotating mechanism 100 to use the elastic force of the compression spring 71 to assist the rotation of the second connecting member 30, which helps reduce the output power requirement of the drive device 50. At this time, as the fan assembly 400 swings downwards towards the support structure 200, the gravity of the fan assembly 400 and the second connecting member 30 acts on the compression spring 71, causing it to undergo elastic compression deformation, which helps the compression spring 71 store a certain amount of elastic potential energy. Furthermore, when the drive device 50 drives the second connecting member 30 to rotate upward relative to the first connecting member 10, the compression spring 71 can restore its elastic deformation and apply a certain elastic force to the second connecting member 30. The direction of this elastic force is opposite to the direction of the second connecting member 30. Therefore, the elastic force applied by the compression spring 71 can offset part of the weight of the second connecting member 30 and the fan assembly 400, thereby reducing the power output required by the drive device 50 to drive the second connecting member 30 to swing the fan assembly 400 upward. This allows the drive device 50 to be equipped with a smaller power device, effectively reducing the overall size of the rotating mechanism 100, achieving a better miniaturized structural design for the oscillating fan 1000, and improving the practicality and structural reliability of the oscillating fan 1000.

[0046] Further, see Figure 10 and Figure 11 In one embodiment of the present invention, the first rib plate 11 is provided with a groove 111 on the side facing the second connector 30. The groove 111 is arc-shaped. The first support member 73 is provided with an arc-shaped protrusion 7311 on the side facing away from the compression spring 71. The arc-shaped protrusion 7311 is rotatably disposed in the groove 111 and abuts against the inner wall of the groove 111.

[0047] In this embodiment, the groove 111 can refer to an arc-shaped recessed structure provided on the surface of the first rib 11, which can be formed by machining or casting processes, and is used to accommodate the arc-shaped protrusion 7311 and provide rotational guidance support. The arc-shaped protrusion 7311 can refer to an arc-shaped protrusion provided on the surface of the first support member 73, and can specifically adopt a structural design that matches the curvature of the groove 111. This reduces frictional resistance through rolling contact with the groove 111. Furthermore, by adjusting the radius of curvature of the arc-shaped protrusion 7311, it can maintain continuous contact with the inner wall of the groove 111 during relative rotation, thereby limiting the lateral displacement of the first support member 73, so that the compression spring 71 can better undergo compression or tension deformation along a straight line.

[0048] Specifically, when the second connector 30 rotates relative to the first connector 10, the first support 73 undergoes displacement changes through the rolling of the arc-shaped protrusion 7311 within the groove 111. The arc-shaped trajectory of the groove 111 can guide the first support 73 to rotate along a predetermined path. Furthermore, the continuous contact between the arc-shaped protrusion 7311 and the inner wall of the groove 111 can prevent the first support 73 from shifting during movement, ensuring sufficient contact and support between the first support 73 and the first rib 11, and ensuring that the elastic component 70 always extends and retracts in a straight line.

[0049] The design of the arc-shaped protrusion 7311 and the groove 111 enhances the anti-deflection capability of the first support 73, ensuring that the compression spring 71 always applies force along the axis during the extension and retraction process, reducing the elasticity loss of the compression spring 71, thereby extending the service life of the elastic component 70 and further improving the structural stability and reliability of the rotating mechanism 100.

[0050] See Figure 2 and Figure 3 In one embodiment of the present invention, the second connecting member 30 includes a seat plate 33, a second rib plate 31 is bent and connected to the side wall of the seat plate 33, and the fan body 41 is connected to the seat plate 33.

[0051] In this embodiment, by bending the second rib 31 and connecting it to the side wall of the seat plate 33, the second connector 30 can be formed into a structure similar to an "L" or "U" shape. This allows the second connector 30 to be stably rotatably connected to the first connector 10, and under the action of the seat plate 33, the second connector 30 can have a larger connection area with the fan assembly 400, ensuring the stable support of the rotating mechanism 100 for the fan assembly 400, and further improving the overall structural stability of the oscillating fan 1000.

[0052] The fan assembly 400 connects and mounts the fan body 41 onto the base plate 33, allowing the second connector 30 to better integrate with the fan body 41, thus enabling the second connector 30 and the fan assembly 400 to more stably and synchronously oscillate, further improving the overall structural stability and reliability of the oscillating fan 1000. The base plate 33 can be securely connected and mounted to the fan body 41 using bolts, screws, and other fasteners, ensuring the fan body 41 is firmly fixed to the base plate 33, achieving more stable and reliable operation of the oscillating fan 1000, and further improving the overall structural stability and reliability of the oscillating fan 1000.

[0053] See Figure 7 and Figure 8 In one embodiment of the present invention, the second rib plate 31 is provided with at least two wiring holes 315, and the oscillating fan 1000 also includes a transmission cable, which is arranged to pass through at least two wiring holes 315 in sequence; the base plate 33 is provided with a wire hole 331 communicating with the fan assembly 400, and the transmission cable passes through the wire hole 331 and is electrically connected to the fan body 41.

[0054] In this embodiment, the transmission cable can be a wire that supplies power or controls the fan body 41. The oscillating fan 1000 can utilize the first connector 10 and the second connector 30 to provide support and fixation for the transmission cable, allowing it to pass through the rotating mechanism 100 and achieving a compact design for the entire oscillating fan 1000. The second connector 30 can have a cable passage hole 331 on the base plate 33, allowing the transmission cable to pass through the hole 331 and connect to the fan body 41 on one side of the base plate 33. This further reduces the cable routing path, minimizes the space occupied by the cable, and improves the practicality and structural reliability of the oscillating fan 1000.

[0055] By opening at least two wiring holes 315 on the second rib 31 for the transmission cable to pass through sequentially, the transmission cable can be wound more neatly on the second rib 31 for routing. At the same time, compared with the method of routing the cable through the upper and lower sides of the second rib 31, having the transmission cable pass through at least two wiring holes 315 also helps to reduce the length of the transmission cable in the rotating mechanism 100, which is conducive to reducing the space occupied by the transmission cable in the oscillating fan 1000, and helps to better realize the overall miniaturization design of the oscillating fan 1000, further improving the practicality and reliability of the oscillating fan 1000.

[0056] See Figure 7 and Figure 8 In one embodiment of the present invention, the second rib plate 31 is provided with a wire passage groove 317 on the plate surface opposite to the base plate 33. The wire passage groove 317 is located between two adjacent wire passage holes 315 and communicates with the two wire passage holes 315. The transmission cable passes through the wire passage groove 317. The second rib plate 31 is also provided with a wire stop plate 319 on the plate surface opposite to the base plate 33. The wire stop plate 319 is exposed in the groove of the wire passage groove 317 and is used to limit the transmission cable.

[0057] In this embodiment, by providing a cable tray 317 on the surface of the second rib 31 facing away from the base plate 33, and by positioning the cable tray 317 between and communicating with two adjacent cable holes 315, the transmission cable can pass through the cable tray 317 from one cable hole 315 to another adjacent cable hole 315. This allows the transmission cable to be contained and confined within the cable tray 317, preventing the transmission cable from protruding from the surface of the second rib 31. This further reduces the space occupied by the transmission cable within the oscillating fan 1000, facilitates the miniaturization design of the oscillating fan 1000, and further improves the stability and reliability of the cable routing within the oscillating fan 1000.

[0058] By setting a wire baffle 319 on the surface of the second rib 31 and exposing the wire baffle 319 at the opening of the wire groove 317, the wire baffle 319 can prevent the transmission cable from coming out of the wire groove 317, thereby achieving a better limiting installation effect of the transmission cable in the wire groove 317, ensuring the stable and reliable routing of the transmission cable on the second connector 30, so that the transmission cable can be more stably electrically connected to the fan body 41, and further improving the structural stability and reliability of the oscillating fan 1000.

[0059] See Figures 5 to 7 In one embodiment of the present invention, the support structure 200 includes a support frame 21 and a horizontal rotation mechanism 23. The horizontal rotation mechanism 23 connects the first connecting member 10 and the support frame 21. The horizontal rotation mechanism 23 is used to drive the rotation mechanism 100 to rotate horizontally relative to the support frame 21.

[0060] In this embodiment, the support frame 21 may include, but is not limited to, a column, tripod, or other frame structure. By setting a horizontal rotation mechanism 23 on the support frame 21 and connecting the first connecting member 10 of the rotation mechanism 100 to the horizontal rotation mechanism 23, the horizontal rotation mechanism 23 may be a motor assembly, which can drive the rotation mechanism 100 to rotate horizontally as a whole; or the horizontal rotation mechanism 23 may be a push rod gear mechanism, which can be provided with a locking tooth on the side of the push rod and mesh with a horizontally rotatable gear, so that the push rod can drive the gear to rotate during the reciprocating movement, thereby driving the rotation mechanism 100 to rotate horizontally as a whole through the gear; of course, the specific structure of the horizontal rotation mechanism 23 is not limited to this, and this application does not limit the specific structure of the horizontal rotation mechanism 23, as long as it can stably drive the rotation mechanism 100 to rotate horizontally relative to the support frame 21.

[0061] Furthermore, under the action of the horizontal rotation mechanism 23, the rotation mechanism 100 and the fan assembly 400 can be stably driven to rotate in the horizontal direction, which can better realize the left and right swing function of the oscillating fan 1000. Combined with the rotation mechanism 100 driving the fan assembly 400 to swing up and down, the oscillating fan 1000 can achieve a wider range of air blowing effect, further improving the practicality and structural reliability of the oscillating fan 1000.

[0062] See Figure 5 and Figure 6 In one embodiment of this utility model, the lateral rotation mechanism 23 includes a first column 231, a second column 233, and a steering motor 235. The first column 231 is connected to the support frame 21; the second column 233 is stacked on top of the first column 231, and the end of the second column 233 facing away from the first column 231 is connected to the first connector 10; the steering motor 235 connects the first column 231 and the second column 233 and drives the second column 233 to rotate relative to the first column 231. And / or, a power connector 237 is provided on the periphery of the lateral rotation mechanism 23, and the oscillating fan 1000 also includes a transmission cable, which is electrically connected to the power connector 237 and passes through the lateral rotation mechanism 23 and the rotation mechanism 100.

[0063] In some embodiments, the horizontal rotation mechanism 23 can be formed by stacking a first column 231 and a second column 233. The first column 231 and the second column 233 can be sleeve structures with a certain cavity, so that the steering motor 235 can be installed in the inner cavity of the first column 231 and the second column 233 and connected to the first column 231 and the second column 233. By connecting and fixing the first column 231 to the support frame 21, the steering motor 235 can be operated by electric drive, so that the steering motor 235 can drive the second column 233 to rotate horizontally relative to the first column 231, that is, the second column 233 can rotate left and right in the horizontal direction. Furthermore, by connecting the end of the second column 233 facing away from the first column 231 to the second connecting member 30 of the rotating mechanism 100, the rotating mechanism 100 and the fan assembly 400 can be driven to rotate together when the second column 233 rotates, thereby realizing the horizontal swing function of the oscillating fan 1000. This allows the oscillating fan 1000 to achieve a wider range of airflow, further improving the practicality and reliability of the oscillating fan 1000.

[0064] By incorporating a steering motor 235 within the horizontal rotation mechanism 23 to drive the second column 233 to rotate, and causing the second column 233 to drive the rotation mechanism 100 to rotate horizontally, the oscillating fan 1000 can integrate both vertical and horizontal oscillation functions. This allows the fan assembly 400 to achieve multiple degrees of freedom of oscillation, effectively increasing the airflow range of the oscillating fan 1000 and enabling it to better meet user needs, further enhancing its practicality and reliability. Furthermore, by connecting and integrating the horizontal rotation mechanism 23 with the rotation mechanism 100, the oscillating fan 1000 can more compactly arrange multiple drive components within a smaller size, facilitating miniaturization and further improving its usability.

[0065] Secondly, refer to Figure 2In some embodiments, the oscillating fan 1000 may have a power connector 237 disposed around the periphery of the horizontal rotation mechanism 23. The power connector 237 is electrically connected to the transmission cable inside the oscillating fan 1000, allowing power to be supplied to the internal electrical equipment via an external power source. The transmission cable can be electrically connected within the oscillating fan 1000 to the drive unit 50 and the fan body 41, ensuring stable power delivery to these devices and guaranteeing stable operation of the oscillating fan 1000. The transmission cable can be routed within the oscillating fan 1000 in the space adjacent to the horizontal rotation mechanism 23 and the rotating mechanism 100; alternatively, corresponding holes or cable fixing structures can be provided on the first connecting member 10 and the second connecting member 30 of the rotating mechanism 100, allowing the transmission cable to be wound around the rotating mechanism 100 for routing, thus reducing the space occupied by the transmission cable and achieving a miniaturized design of the oscillating fan 1000.

[0066] The power connector 237 can be plugged into a wire with a power terminal at the end, allowing the oscillating fan 1000 to be powered by an external power source. By providing the power connector 237 on the oscillating mechanism 23, the oscillating fan 1000 can be easily disassembled and used, reducing the dragging of the power cord when the oscillating fan 1000 is stored, and further improving the practicality of the oscillating fan 1000.

[0067] See Figure 10 and Figure 11 In one embodiment of the present invention, the first rib plate 11 is provided with a groove 111 on the side facing the second connector 30. The groove 111 is arc-shaped. The first support member 73 is provided with an arc-shaped protrusion 7311 on the side facing away from the compression spring 71. The arc-shaped protrusion 7311 is rotatably disposed in the groove 111 and abuts against the inner wall of the groove 111.

[0068] In this embodiment, the groove 111 can refer to an arc-shaped recessed structure provided on the surface of the first rib 11, which can be formed by machining or casting processes, and is used to accommodate the arc-shaped protrusion 7311 and provide rotational guidance support. The arc-shaped protrusion 7311 can refer to an arc-shaped protrusion provided on the surface of the first support member 73, and can specifically adopt a structural design that matches the curvature of the groove 111. This reduces frictional resistance through rolling contact with the groove 111. Furthermore, by adjusting the radius of curvature of the arc-shaped protrusion 7311, it can maintain continuous contact with the inner wall of the groove 111 during relative rotation, thereby limiting the lateral displacement of the first support member 73, so that the compression spring 71 can better undergo compression or tension deformation along a straight line.

[0069] Specifically, when the second connector 30 rotates relative to the first connector 10, the first support 73 undergoes displacement changes through the rolling of the arc-shaped protrusion 7311 within the groove 111. The arc-shaped trajectory of the groove 111 can guide the first support 73 to rotate along a predetermined path. Furthermore, the continuous contact between the arc-shaped protrusion 7311 and the inner wall of the groove 111 can prevent the first support 73 from shifting during movement, ensuring sufficient contact and support between the first support 73 and the first rib 11, and ensuring that the elastic component 70 always extends and retracts in a straight line.

[0070] The design of the arc-shaped protrusion 7311 and the groove 111 enhances the anti-deflection capability of the first support 73, ensuring that the compression spring 71 always applies force along the axis during the extension and retraction process, reducing the elasticity loss of the compression spring 71, thereby extending the service life of the elastic component 70 and further improving the structural stability and reliability of the rotating mechanism 100.

[0071] See Figure 12 and Figure 14 In one embodiment of the present invention, the first support member 73 includes a base plate 731 and a support rod 733. The arc-shaped protrusion 7311 and the support rod 733 are respectively connected to two opposite surfaces of the base plate 731. The compression spring 71 is sleeved on the outer periphery of the support rod 733 and spaced apart from the outer periphery of the support rod 733. One end of the compression spring 71 is connected to or abuts against the base plate 731. The second support member 75 is provided with a clearance hole 751, through which the support rod 733 is movably disposed.

[0072] In this embodiment, the base plate 731 can refer to a plate-like structure that supports the support rod 733 and the arc-shaped protrusion 7311, and can be used to distribute the force on the compression spring 71 and maintain the verticality of the support rod 733. The support rod 733 can refer to a columnar component fixed on the base plate 731 and coaxially arranged with the compression spring 71, and can be used to limit the radial displacement of the compression spring 71 and provide a certain degree of support for the compression spring 71. The clearance hole 751 can refer to a through hole provided on the second support member 75, which allows the support rod 733 to slide axially through it when the second support member 75 rotates. There can be a certain annular gap between the compression spring 71 and the support rod 733 to avoid contact and friction between the compression spring 71 and the support rod 733 when the compression spring 71 extends and retracts, thereby better reducing the elasticity loss of the compression spring 71 and ensuring a more reliable support effect of the elastic component 70 on the second connecting member 30.

[0073] Specifically, when the second connecting member 30 rotates relative to the first connecting member 10, the first support member 73 and the second support member 75 move with the second connecting member 30, which can drive the support rod 733 to slide axially within the clearance hole 751. Under the guidance of the support rod 733, the compression spring 71 can more stably generate elastic deformation along a straight line, ensuring that the elastic force assembly 70 provides more reliable support for the second connecting member 30. The spacing between the support rod 733 and the compression spring 71 can effectively prevent the compression spring 71 from rubbing against the surface of the support rod 733 during compression or extension, reducing elastic force loss and allowing the elastic force assembly 70 to apply more sufficient elastic force to support the second connecting member 30. The rigid connection between the base plate 731 and the support rod 733 can better ensure that the extension and contraction direction of the compression spring 71 is consistent with the axis of the support rod 733, effectively avoiding the skew deformation of the compression spring 71, and further improving the overall structural stability and reliability of the rotating mechanism 100.

[0074] Through the above technical solution, this application can effectively reduce the elasticity loss of the compression spring 71 during the extension and contraction process, improve the energy transmission efficiency of the elastic component 70, and ensure the smoothness of the rotation process through the cooperation of the support rod 733 and the clearance hole 751. This structural design enables the rotating mechanism 100 to achieve efficient force transmission within a limited space, adapts to the compact layout requirements of miniaturized equipment, and better realizes the miniaturized design of the rotating mechanism 100, so that the rotating mechanism 100 can be adapted for use in more equipment.

[0075] See Figure 12 and Figure 14 In one embodiment of the present invention, the bottom plate 731 is provided with two spaced and opposite limiting baffles 7313 on the plate surface opposite to the support rod 733, and an arc-shaped protrusion 7311 is provided between the two limiting baffles 7313. The two limiting baffles 7313 are respectively abutted against the opposite sides of the first rib plate 11.

[0076] In this embodiment, the limiting baffle 7313 can be a plate-shaped structure perpendicular to the base plate 731. Two opposing limiting baffles 7313 and the base plate 731 can form a certain groove structure, allowing part of the first rib 11 to be inserted into the groove. The arc-shaped protrusion 7311 engages with the groove 111 of the first rib 11 within the groove, thereby limiting the engagement between the arc-shaped protrusion 7311 and the groove 111. This better prevents the arc-shaped protrusion 7311 from sliding laterally out of the groove 111, further improving the stability and reliability of the rotational connection of the first support member 73 on the first rib 11, and ensuring the supporting effect of the elastic component 70 on the rotation of the second connector 30.

[0077] See Figures 10 to 13In one embodiment of the present invention, in a direction perpendicular to the plane of the second rib 31, the two opposite sides of the second support member 75 are respectively provided with connecting shafts 753; the second rib 31 is provided with a receiving space, and the two opposite inner walls of the second rib 31 in the receiving space are respectively provided with connecting holes 3131; at least a part of the structure of the second support member 75 is rotatably disposed in the receiving space, and the two connecting shafts 753 are respectively rotatably inserted into the two connecting holes 3131.

[0078] In some embodiments, the connecting shaft 753 may refer to the cylindrical protrusions disposed on both sides of the second support member 75, which are used to cooperate with the connecting holes 3131 of the second rib 31 to form a rotating pair. The connecting hole 3131 may refer to a through hole structure disposed on the inner wall of the receiving space, the diameter of which matches the diameter of the connecting shaft 753 to achieve a clearance fit or a transition fit. The receiving space can be formed by stamping or modular assembly of the second rib 31, and can be used to accommodate at least a part of the structure of the second support member 75 to limit its displacement range, thereby achieving a stable rotational connection between the second support member 75 and the second rib 31.

[0079] Specifically, the second support member 75 is inserted into the connecting holes 3131 of the second rib plate 31 via connecting shafts 753 on both sides, forming a rotatable connection around the axis, thus achieving a stable rotatable connection between the second support member 75 and the second connector 30. The main body of the second support member 75 can be enclosed by the receiving space, so that its displacement range during rotation is limited by the side walls of the receiving space, effectively preventing the second support member 75 from detaching from the second rib plate 31, and achieving reliable support for the second connector 30 by the elastic component 70. When the second connector 30 rotates relative to the first connector 10, the second support member 75 rotates synchronously with the second connector 30, while the connecting shafts 753 rotate within the connecting holes 3131. Since the fit clearance between the connecting shaft 753 and the connecting hole 3131 is controlled within a reasonable range, it ensures the degree of freedom of rotation and avoids the swaying of the support due to excessive clearance. This allows the compression spring 71 to undergo elastic deformation more stably along a straight line, better reduce elastic force loss, ensure the supporting effect of the elastic component 70 on the second connecting member 30, and further improve the structural stability and reliability of the rotating mechanism 100.

[0080] See Figure 9 In one embodiment of the present invention, the first rib 11 is provided with one of a limiting block 113 or a limiting groove 3111, and the second rib 31 is provided with the other of a limiting block 113 or a limiting groove 3111. The limiting groove 3111 extends along the rotation direction of the second connector 30. The limiting block 113 is disposed in the limiting groove 3111 and can abut against the two opposite inner sidewalls of the limiting groove 3111 for limiting.

[0081] In some embodiments, the limiting block 113 can refer to a physical structure used to limit the rotation angle, and the limiting groove 3111 can refer to a guide structure used to accommodate the limiting block 113. Specifically, it can be implemented using an arc-shaped groove 111 or a straight slide, the extension direction of which matches the rotation trajectory. Specifically, when the second connecting member 30 rotates relative to the first connecting member 10, the limiting block 113 can move synchronously within the limiting groove 3111, and the limiting groove 3111 plays a certain guiding and limiting role in the movement of the limiting block 113, preventing the limiting block 113 from disengaging. When the second connecting member 30 rotates relative to the first connecting member 10 to a certain preset angle, the limiting block 113 contacts the groove wall to form a physical block, effectively limiting the rotation angle of the second connecting member 30 relative to the first connecting member 10, further improving the practicality and reliability of the rotating mechanism 100.

[0082] See Figures 9 to 11 In one embodiment of the present invention, the first connector 10 is provided with two first ribs 11, which are arranged opposite each other at intervals. The second connector 30 is provided with two second ribs 31, which are arranged opposite each other at intervals. Each second rib 31 is respectively configured to cooperate with a first rib 11.

[0083] In some embodiments, by providing two spaced-apart opposing first ribs 11 to the first connector 10, the first connector 10 can form a U-shaped structure; and by providing two spaced-apart opposing second ribs 31 to the second connector 30, the second connector 30 can form a U-shaped structure. The symmetrical arrangement of the two first ribs 11 and the two second ribs 31 forms four sets of support points. Through the synergistic effect of the paired ribs, the load of the drive device 50 is distributed, and the stress concentration at a single connection point is reduced. This achieves a more stable and reliable connection between the first connector 10 and the second connector 30, preventing the second connector 30 from detaching from the first connector 10 during rotation, and further improving the structural stability and reliability of the rotating mechanism 100.

[0084] See Figure 11 and Figure 12 In one embodiment of this utility model, the second rib 31 includes a main body plate 311 and a mounting sleeve 313. The mounting sleeve 313 is connected to one side of the main body plate 311 and has a receiving space. The mounting sleeve 313 has a connecting hole 3131 on the side facing the first connector 10. Alternatively, the second rib 31 includes a first plate and a second plate, which are spaced apart from each other to form a receiving space. The facing surfaces of the first plate and the second plate are respectively provided with connecting holes 3131.

[0085] In some embodiments, the main body plate 311 can refer to a base plate structure used to support the mounting sleeve 313, serving to support and fix the mounting sleeve 313. The mounting sleeve 313 can refer to a sleeve structure connected to the main body plate 311, and can be assembled with the main body plate 311 by welding or bolting. The mounting sleeve 313 can be used to form a receiving space and provide a connection hole 3131. Specifically, the mounting sleeve 313 and the main body plate 311 form an integrated structure, the receiving space is confined inside the mounting sleeve 313, and the connection hole 3131 is opened on the side of the mounting sleeve 313 facing the first connecting member 10, allowing the connecting shaft 753 of the second support member 75 to be directly inserted into the connection hole 3131 to complete the assembly, achieving a stable rotational connection between the second support member 75 and the second rib plate 31, further improving the structural stability and reliability of the rotating mechanism 100.

[0086] In other embodiments, the first plate and the second plate can refer to parallel plate-like structures, with the two plates spaced apart to form a receiving space, so that the first plate and the second plate form the inner wall of the receiving space to limit and constrain the second support member 75. Specifically, the first plate and the second plate are spaced apart to form a receiving space, and connecting holes 3131 are respectively opened on the opposite inner walls of the two plates. The connecting shaft 753 of the second support member 75 is simultaneously inserted into the connecting holes 3131 on both sides, forming a symmetrical support structure 200, realizing a stable rotational connection between the second support member 75 and the second rib plate 31, further improving the structural stability and reliability of the rotation mechanism 100.

[0087] See Figure 3 and Figure 4 In one embodiment of the present invention, the driving device 50 includes a rotating shaft assembly 51 and a driving motor 53. The rotating shaft assembly 51 passes through and connects the first rib 11 and the second rib 31. The driving motor 53 connects the first rib 11 and / or the second rib 31 and drives the second connecting member 30 to rotate relative to the first connecting member 10.

[0088] In this embodiment, the first rib 11 and the second rib 31 are connected by the rotating shaft assembly 51, enabling the second connecting member 30 to rotate stably relative to the first connecting member 10 around the central axis of the rotating shaft assembly 51, thus achieving stable rotation of the rotating mechanism 100. The driving device 50 can be connected and mounted on the first rib 11, allowing it to indirectly drive the second connecting member 30 to rotate via gear transmission, belt transmission, or other means; alternatively, the second rib 31 can be engaged with the rotating shaft assembly 51, allowing the driving device 50 to directly drive the rotating shaft assembly 51 and the second rib 31 to rotate. Furthermore, the driving device 50 can also be connected and mounted on the second rib 31, similarly enabling the second connecting member 30 to rotate synchronously by indirectly driving the rotating shaft assembly 51, or by directly driving the second connecting member 30 to rotate, ensuring stable rotation of the second connecting member 30. In addition, the drive device 50 can also connect the first rib 11 and the second rib 31 at the same time, which facilitates the spatial layout design of the rotating mechanism 100, so that the drive device 50 can more stably drive the second connecting member 30 to rotate relative to the first connecting member 10 by a certain angle, realize the steering function of the rotating mechanism 100, and further improve the practicality and structural reliability of the rotating mechanism 100.

[0089] See Figure 9 and Figure 10 In one embodiment of this utility model, a drive motor 53 is mounted on a first rib 11, and a drive wheel 531 is connected to the rotating shaft of the drive motor 53. A transmission rack 3113 is provided on the surface of the second rib 31 facing the first rib 11. The transmission rack 3113 extends along the rotation direction of the second connecting member 30, and the drive wheel 531 meshes with the transmission rack 3113. Alternatively, the rotating shaft assembly 51 includes a bushing 511, a shaft body 513, and a bearing 515. The bushing 511 is disposed between the first rib 11 and the second rib 31, and connects the first rib 11 and / or the second rib 31. The bushing 511 has a fixing groove 5111, and the bearing 515 is fixedly disposed in the fixing groove 5111. The shaft body 513 passes through the first rib 11, the bushing 511, and the second rib 31, and the bearing 515 is sleeved on the outer periphery of the shaft body 513.

[0090] In this embodiment, the drive device 50 can mount and fix the drive motor 53 on the first rib plate 11, and can set the drive wheel 531 on the rotating shaft of the drive motor 53. By setting the transmission rack 3113 on the side of the second rib plate 31 facing the first rib plate 11, the transmission rack 3113 can be provided with multiple teeth that cooperate with the drive wheel 531. Furthermore, the rack can be set in an arc structure with an arc equal to the swing path of the second connecting member 30, so that when the drive motor 53 drives the drive wheel 531 to rotate, the drive wheel 531 can mesh with and drive the transmission rack 3113 and the second connecting member 30 to rotate around the rotating shaft assembly 51, thereby realizing the stable swing operation of the rotating mechanism 100. By utilizing the gear meshing action of the drive motor 53 and the transmission rack 3113 to drive the second connecting member 30 to swing in the up and down direction, the structural setting of the drive device 50 on the second connecting member 30 can be better simplified, which is conducive to reducing the overall weight of the second connecting member 30. This allows the drive device 50 to drive the second connecting member 30 to swing relative to the first connecting member 10 at a lower operating power, further improving the practicality and reliability of the rotating mechanism 100.

[0091] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
