Technical Field

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

[0002] In related technologies, fans can typically have an oscillation mechanism installed between the bracket and the fan assembly. This oscillation mechanism can be used to drive the fan assembly to swing up and down relative to the bracket, so that the fan can achieve a wider range of airflow.

[0003] However, most existing fan components are quite heavy, requiring motors with high output power for the oscillation mechanism to ensure stable drive of the fan component. This results in the current oscillation mechanisms being mostly large in size, with high production costs, hindering the miniaturization of fans and reducing their practicality. Utility Model Content

[0004] The main purpose of this utility model is to propose an oscillation mechanism and a fan, which aims to improve the structural design of the oscillation mechanism and enhance the practicality and structural reliability of the fan.

[0005] To achieve the above objectives, the oscillating mechanism proposed in this utility model includes a support member, an oscillating member, a drive assembly, and an elastic member. The support member is used to connect to a bracket; the oscillating member is used to connect to a fan assembly; the drive assembly includes a connecting shaft and a drive device, the connecting shaft passing through and connecting the support member and the oscillating member, the drive device being connected to either the support member or the oscillating member, and the drive device driving the oscillating member to oscillate up and down relative to the support member around the central axis of the connecting shaft; the elastic member extends in the vertical direction, has two opposing ends, one end of the elastic member being connected to the support member, and the other end of the elastic member being connected to the oscillating member.

[0006] In one embodiment, the support member is provided with a support seat, the swing member is provided with a connecting web, and the connecting shaft connects the support seat and the connecting web. A first mounting protrusion is provided on one side of the support seat, and a second mounting protrusion is provided on one side of the connecting web. The two ends of the elastic member are respectively connected to the first mounting protrusion and the second mounting protrusion.

[0007] In one embodiment, the connecting web is provided with a wire fixing structure for securing and fixing the transmission cable.

[0008] In one embodiment, the connecting shaft includes a bearing structure and a shaft body. The bearing structure is connected to the support seat and / or the connecting web. The bearing structure is sleeved on the outer periphery of the shaft body, and the shaft body passes through the support seat and the connecting web.

[0009] In one embodiment, retaining rings are respectively engaged at both ends of the shaft, and the retaining rings are used to limit and fix the shaft to prevent the shaft from moving along the axial direction.

[0010] In one embodiment, the driving device includes a drive motor and a transmission structure. The drive motor is mounted on the support base, and the drive motor's shaft is connected to a drive wheel. The transmission structure is connected to the connecting web plate and is equipped with a rack, which meshes with the drive wheel.

[0011] In one embodiment, the support base has a receiving space, the drive motor is located in the receiving space, and the two ends of the drive motor respectively abut against the two opposite inner sidewalls of the receiving space.

[0012] In one embodiment, the support member is provided with a first limiting structure, and the swing member is provided with a second limiting structure. The first limiting structure and the second limiting structure can cooperate to abut against each other to limit the angle of rotation of the swing member relative to the support member.

[0013] In one embodiment, the support member includes a first connecting column, a second connecting column, and a steering mechanism. The second connecting column is stacked on top of the first connecting column, and the end of the second connecting column facing away from the first connecting column is connected to the swing member. The steering mechanism connects the first connecting column and the second connecting column and drives the second connecting column to rotate relative to the first connecting column.

[0014] This utility model also proposes a fan, which includes a bracket, an oscillation mechanism, and a fan assembly. The oscillation mechanism is the oscillation mechanism described above, and the oscillation mechanism connects the bracket and the fan assembly.

[0015] The technical solution of this utility model utilizes an elastic element extending in the vertical direction to connect the support element and the swinging element. When the swinging element drives the fan assembly to swing downwards, the gravity acting on the elastic element acts on the elastic element, allowing the elastic element to be in an elastic deformation state when the swinging element swings downwards. Then, when the drive assembly drives the swinging element to swing upwards, the elastic force generated by the elastic element recovering its elastic deformation acts on the swinging element, so that the elastic element can assist the drive assembly in pulling the swinging element upwards. This allows the drive assembly to use a lower power equipment, effectively reducing the overall size of the oscillating mechanism, lowering the production cost of the oscillating mechanism, and improving the practicality and structural reliability of the oscillating mechanism.

[0029] In related technologies, fans typically incorporate an oscillation mechanism between the support frame and the fan assembly. This mechanism drives the fan assembly to swing up and down relative to the support frame, allowing the fan to achieve a wider airflow range. However, existing fan assemblies are mostly heavy, requiring the oscillation mechanism to use a high-power motor to ensure stable drive of the fan assembly. This results in current oscillation mechanisms being generally large, increasing production costs, hindering miniaturization of the fan, and reducing its practicality.

[0030] It is understandable that fan assemblies typically include a fan, blades, and a housing. The overall weight of the fan assembly is relatively large. To ensure stable lifting of the fan assembly, most current oscillation mechanisms use high-power motors to drive the fan assembly to oscillate up and down, so that the oscillation mechanism can meet the load requirements of the fan's oscillation motion. However, high-power motors are generally large in size, which easily leads to a large protrusion at the location of the oscillation mechanism, affecting the fan's aesthetics and hindering miniaturization design. At the same time, high-power motors are often expensive, resulting in higher overall production costs and reducing the fan's practicality. To address these problems, this utility model proposes an oscillation mechanism 100.

[0031] Please see Figures 1 to 6 In one embodiment of the present invention, the oscillating mechanism 100 includes a support member 10, an oscillating member 30, a driving assembly 50, and an elastic member 70. The support member 10 is used to connect the bracket 200; the oscillating member 30 is used to connect the fan assembly 400; the driving assembly 50 connects the support member 10 and the oscillating member 30, and is used to drive the oscillating member 30 to oscillate in the up-down direction relative to the support member 10; the elastic member 70 extends in the up-down direction and has two opposite ends. One end of the elastic member 70 is connected to the support member 10, and the other end of the elastic member 70 is connected to the oscillating member 30.

[0032] In this application, the support member 10 can be installed and connected to the end of the support 200 such as a column or tripod to achieve a stable connection between the oscillating mechanism 100 and the fan 1000 support 200, ensuring the support function for the fan assembly 400; while the swing member 30 can be a sheet metal structure or the like that connecting the fan assembly 400. By using the drive component 50 to connect the support member 10 and the swing member 30, the swing member 30 can swing relative to the support member 10 in the up and down direction under the drive action of the drive component 50, that is, the oscillating mechanism 100 can drive the fan assembly 400 to swing up and down, ensuring the stable operation of the fan 1000. The drive assembly 50 can be configured to directly connect the support member 10 and the swing member 30 via the motor's connecting shaft 51, allowing the motor to directly drive the swing member 30 to swing relative to the support member 10. Alternatively, it can utilize a combination of the motor and the connecting shaft 51, connecting the support member 10 and the swing member 30, and then using a transmission connection between the motor and the swing member 30 to drive the swing member 30 to swing relative to the support member 10. Another option is to employ a telescopic push rod structure, allowing the drive assembly 50 to push and drive the swing member 30 to swing vertically relative to the support member 10. There are many ways for the drive assembly 50 to drive the swing member 30 to swing vertically relative to the support member 10, and this application does not limit this method. For ease of understanding and explanation, this application uses the term "swing member 30" to refer to various ways of swinging the swing member 30 relative to the support member 10. Figure 4The coordinate system shown in the figure indicates the directions as references. The up and down direction is the positive direction of the z-axis, the forward and backward direction is the positive direction of the x-axis, and the left and right direction is the positive direction of the y-axis. The positive direction of the x-axis is right, and the negative direction of the x-axis is left. The positive direction of the y-axis is forward, and the negative direction of the y-axis is backward. The positive direction of the z-axis is up, and the negative direction of the z-axis is down.

[0033] By connecting the support member 10 and the swing member 30 with an elastic element 70 extending in the vertical direction, the elastic force of the elastic element 70 can be effectively used to assist the relative movement of the swing member 30 and the support member 10. The elastic element 70 can be a tension spring, compression spring, or leaf spring, etc., which have a certain elastic extension function. In addition, the elastic element 70 can extend in a direction parallel to the vertical direction, that is, the elastic element 70 can be vertically extended; or, the elastic element 70 can extend in a direction at a certain angle to the vertical direction, that is, the elastic element 70 can be inclined. Furthermore, the oscillating mechanism 100 allows the oscillating member 30 to swing to its lowest position in the vertical direction. At this point, the elastic member 70 is subjected to the gravity of the oscillating member 30 and the fan assembly 400, causing it to be in an elastic deformation state. This allows the elastic member 70 to exert a certain traction force on the oscillating member 30 during the process of the drive assembly 50 driving the oscillating member 30 to rise and swing relative to the support member 10. This enables the elastic member 70 to assist the drive assembly 50 in driving the oscillating member 30, which helps to reduce the power requirements of the drive assembly 50. This reduces the motor power requirements of the drive assembly 50, allowing for a smaller component design in the drive assembly 50, lowering the overall structural cost of the oscillating mechanism 100, and reducing the size of the drive assembly 50, thus achieving a more miniaturized design of the oscillating mechanism 100.

[0034] The technical solution of this utility model utilizes an elastic element 70 extending in the vertical direction to connect the support element 10 and the swing element 30. When the swing element 30 drives the fan assembly 400 to swing downward, the gravity acting on the elastic element 70 allows the elastic element 70 to be in an elastic deformation state when the swing element 30 swings downward. Then, when the drive assembly 50 drives the swing element 30 to swing upward, the elastic force generated by the elastic element 70 recovering its elastic deformation can act on the swing element 30. This allows the elastic element 70 to assist the drive assembly 50 in pulling the swing element 30 upward, enabling the drive assembly 50 to use a lower power device, effectively reducing the overall size of the oscillating mechanism 100, lowering the production cost of the oscillating mechanism 100, and improving the practicality and structural reliability of the oscillating mechanism 100.

[0035] See Figure 3 and Figure 4In one embodiment of this utility model, the support member 10 is provided with a support seat 11, the swing member 30 is provided with a connecting web 31, and the drive assembly 50 is connected to the support seat 11 and the connecting web 31. A first mounting protrusion 111 is provided on one side of the support seat 11, and a second mounting protrusion 311 is provided on one side of the connecting web 31. The two ends of the elastic member 70 are respectively connected to the first mounting protrusion 111 and the second mounting protrusion 311.

[0036] In this embodiment, the support member 10 may have a support seat 11 protruding from its end face. The support seat 11 may be a sheet metal structure with a certain structural strength that is erected on the end face of the support member 10, or it may be a block structure with a certain volume thickness, etc. In this case, the swing member 30 may have a connecting web 31 protruding from its side near the support member 10. The connecting web 31 may be a sheet metal structure with a certain structural strength. The connecting web 31 may be positioned on the outer side wall of the support seat 11, or it may be positioned on the inner side wall of the support seat 11. Furthermore, the drive assembly 50 may be positioned between the connecting web 31 and the support seat 11. The drive assembly 50 drives the connecting web 31 to rotate relative to the support seat 11, thereby realizing the swing design of the swing member 30 relative to the support member 10 in the vertical direction and ensuring the stable operation of the swaying mechanism 100.

[0037] By providing a first mounting protrusion 111 on one side of the support base 11 and a second mounting protrusion 311 on one side of the connecting web 31, the first mounting protrusion 111 and the second mounting protrusion 311 can be arranged opposite each other in the vertical direction, so that both ends of the elastic member 70 can be connected to the first mounting protrusion 111 and the second mounting protrusion 311. This achieves the connection and support of the elastic member 70 for the support member 10 and the swing member 30, allowing the elastic member 70 to stably pull the swing member 30 when the drive assembly 50 drives the swing member 30 to rise relative to the support member 10, reducing the load on the drive assembly 50. Furthermore, by using the first mounting protrusion 111 and the second mounting protrusion 311 to connect and install the elastic member 70, the elastic member 70 can be better positioned to avoid the drive assembly 50, achieving a more reasonable and compact spatial layout of the oscillating mechanism 100. At the same time, it facilitates the maintenance and replacement of the elastic member 70, further improving the practicality and structural reliability of the oscillating mechanism 100.

[0038] See Figure 4 In one embodiment of this utility model, the connecting web plate 31 is provided with a wire fixing structure 313, which is used to clamp and fix the transmission cable 600.

[0039] Understandably, the fan 1000 allows the transmission cable 600 connecting to the fan assembly 400 to pass through the oscillating mechanism 100 for wiring, facilitating power connection of the fan 1000 at the bracket 200 and enabling more convenient operation of the fan 1000. The transmission cable 600 inside the fan 1000 can sequentially pass through the support member 10 and the oscillating member 30 to enter the fan assembly 400 and electrically connect with components such as the fan, ensuring stable power transmission of the transmission cable 600. At this time, by setting a fixing structure 313 on one side of the connecting web plate 31, the transmission cable 600 can be snapped and fixed onto the fixing structure 313 when it runs towards the oscillating member 30. This fixing structure 313 can have two adjacent through holes, with a buckle between the two through holes, allowing the transmission cable 600 to pass through the fixing structure 313 from the through hole near the support base 11 and be secured by the buckle. Then, the transmission cable 600 passes through the oscillating member 30 from the other through hole and connects to the fan assembly 400. Therefore, under the action of the fixed wire structure 313, the fixed routing of the transmission cable 600 in the oscillating mechanism 100 can be better realized, which helps to reduce the interference of the transmission cable 600 with other components in the oscillating mechanism 100. At the same time, it can also better reduce the pulling effect on the transmission cable 600 when the oscillating member 30 swings relative to the support member 10, ensure the stable wiring of the fan 1000, and further improve the structural stability and reliability of the oscillating mechanism 100.

[0040] See Figure 4 and Figure 5 In one embodiment of the present invention, the drive assembly 50 includes a connecting shaft 51 and a drive device 53. The connecting shaft 51 connects the support base 11 and the connecting web 31. The drive device 53 is connected to the support member 10 or the swing member 30. The drive device 53 drives the swing member 30 to swing relative to the support member 10 around the central axis of the connecting shaft 51.

[0041] In this embodiment, the drive assembly 50 can utilize a connecting shaft 51 passing through the support base 11 and the connecting web 31, and connecting the support base 11 and the connecting web 31, so that the connecting web 31 can rotate around the central axis of the connecting shaft 51 under the action of the connecting shaft 51. At this time, the drive device 53 can be connected and installed on the support member 10, and the drive device 53 can be connected and transmitted to the swing member 30; or, the drive device 53 can be connected and installed on the swing member 30, and the drive device 53 can be connected and transmitted to the support member 10. The drive device 53 can be a combination structure of motor and gear transmission, or it can be a telescopic push rod structure, etc., so that under the action of the drive device 53 and the connecting shaft 51, the swing member 30 can be stably driven to swing relative to the support member 10 around the central axis of the connecting shaft 51, realizing the up and down swing function of the fan 1000, and further improving the structural stability and reliability of the oscillation mechanism 100.

[0042] See Figure 4 and Figure 5 In one embodiment of the present invention, the connecting shaft 51 includes a bearing structure 511 and a shaft body 513. The bearing structure 511 is connected to the support seat 11 and / or the connecting web 31. The bearing structure 511 is sleeved on the outer periphery of the shaft body 513. The shaft body 513 passes through the support seat 11 and the connecting web 31.

[0043] It is understood that the connecting shaft 51 may include a shaft body 513 that passes through the support base 11 and the connecting web 31, and a bearing structure 511 sleeved on the outer periphery of the shaft body 513. Under the action of the bearing structure 511, the shaft body 513 can achieve a smoother rotation effect and reduce the friction when the shaft body 513 rotates. Furthermore, a through hole can be provided on the side wall of the support base 11, so that the bearing structure 511 can be installed and fixed in the through hole, allowing the shaft 513 to pass through the bearing structure 511 on the support base 11 and connect with the connecting web 31; or, a through hole can be provided on the side wall of the connecting web 31, so that the bearing structure 511 can be installed and fixed in the through hole, and the support base 11 can be provided with corresponding bearing holes, allowing the shaft 513 to pass through the bearing structure 511 and the bearing holes to connect the support base 11 and the connecting web 31; or, bearing structures 511 can be provided on both the support base 11 and the connecting web 31, so that the shaft 513 can be sequentially inserted into the bearing structures 511 of the support base 11 and the connecting web 31. By utilizing the matching design of the bearing structure 511 and the shaft 513, the frictional force between the connecting shaft 51 and the support 10 and the swinging member 30 can be effectively reduced, which is conducive to better reducing the load on the drive device 53, so that the drive assembly 50 can be better equipped with a drive device 53 with lower power, and further improve the practicality and reliability of the oscillating mechanism 100.

[0044] Furthermore, when the support base 11 or the connecting web 31 is constructed using sheet metal, the bearing structure 511 may also include a bearing housing and a bearing body. The bearing housing can be snapped onto the support base 11 or the connecting web 31, and the bearing body can be fixedly installed in the bearing housing. This allows the bearing structure 511 to be more stably and reliably connected and installed on the support base 11 or the connecting web 31, avoiding the possibility of the bearing not being able to be properly installed due to the insufficient thickness of the support base 11 or the connecting web 31. This eliminates the need for the support base 11 and the connecting web 31 to adopt a more complex structural design, thereby increasing production costs and further improving the practicality and structural reliability of the swaying mechanism 100.

[0045] See Figure 4 and Figure 5 In one embodiment of the present invention, retaining rings 515 are respectively engaged at both ends of the shaft 513. The retaining rings 515 are used to limit and fix the shaft 513 to prevent the shaft 513 from moving along the axial direction.

[0046] In this embodiment, the outer diameter of the retaining ring 515 can be larger than the through hole diameter of the support base 11 or the connecting web 31 through which the shaft 513 passes. When the connecting web 31 is located on the outer side wall of the support base 11, the retaining ring 515 can be snapped onto the end of the shaft 513 and abut against the side of the connecting web 31 opposite to the support base 11. If the drive device 53 has a transmission structure 533 connected to the connecting web 31, the retaining ring 515 can also abut against the transmission structure 533. Alternatively, when the connecting web 31 is located on the inner side wall of the support base 11, the retaining ring 515 can be... The shaft 513 is snapped into the end of the shaft body 513 and abuts against the outer wall of the support seat 11. Thus, the shaft body 513 can be stably set between the support seat 11 and the connecting web plate 31 under the limiting and fixing action of the two retaining rings 515, preventing the shaft body 513 from moving along its central axis. This helps to better reduce the noise and wear generated by the movement of the shaft body 513, and further reduce the friction between the shaft body 513 and the support seat 11 and the connecting web plate 31, so that the swinging member 30 can swing more smoothly relative to the support seat 11, and further improve the structural stability and reliability of the swaying mechanism 100.

[0047] See Figure 4 and Figure 5 In one embodiment of the present invention, the driving device 53 includes a driving motor 531 and a transmission structure 533. The driving motor 531 is mounted on the support base 11, and the shaft of the driving motor 531 is connected to a drive wheel 5315. The transmission structure 533 is connected to the connecting web plate 31, and the transmission structure 533 is provided with a rack 5331, which meshes with the drive wheel 5315.

[0048] In this embodiment, the drive device 53 can mount and fix the drive motor 531 on the support base 11, and can set the drive wheel 5315 on the rotating shaft of the drive motor 531. By setting the transmission structure 533 on the side of the connecting web 31 facing the drive motor 531, the transmission structure 533 can be a rack 5331 structure set on the plate surface of the connecting web 31. The rack 5331 can be provided with multiple teeth that cooperate with the drive wheel 5315. Furthermore, the rack 5331 can be set in an arc shape with an arc equal to the swing path of the second mounting member 30, so that when the drive motor 531 drives the drive wheel 5315 to rotate, the drive wheel 5315 can mesh and drive the rack 5331 and the swing member 30 to rotate around the connecting shaft 51, thereby realizing the stable swing operation of the swaying mechanism 100. By utilizing the gear meshing action of the drive motor 531 and the transmission structure 533 to drive the oscillating member 30 to swing in the up and down direction, the structural setting of the drive device 53 on the oscillating member 30 can be better simplified, which is conducive to reducing the overall weight of the oscillating member 30. This allows the drive device 53 to drive the oscillating member 30 to swing relative to the support member 10 at a lower operating power, ensuring the stable swing operation of the fan 1000 and further improving the practicality and reliability of the oscillation mechanism 100.

[0049] See Figure 5 and Figure 6 In one embodiment of the present invention, the support base 11 is provided with a receiving space, and the drive motor 531 is located in the receiving space. The two ends of the drive motor 531 respectively abut against the two opposite inner sidewalls of the receiving space.

[0050] In this embodiment, the support base 11 can adopt a combined structure design of a base and a vertical seat plate, so that a receiving space is formed between the seat plate and the base; or the support base 11 can have a box-like structure design, so that the inner cavity of the support base 11 forms a receiving space, allowing the drive motor 531 to be housed and installed in the receiving space of the support base 11, which facilitates a more compact structural design of the oscillating mechanism 100 and further reduces the overall structural size of the oscillating mechanism 100. At this time, when the connecting web plate 31 is set at the outer side wall of the support base 11, a through hole communicating with the receiving space can be provided on the side wall of the support base 11, so that the shaft of the drive motor 531 can pass through the through hole, and the drive wheel 5315 is located on the outer side wall of the support base 11 and connected to the shaft of the drive motor 531, ensuring the stable drive of the support member 10 by the drive motor 531, and further improving the structural stability and reliability of the oscillating mechanism 100.

[0051] In addition, by having the two opposite ends of the drive motor 531 abut against the two opposite inner walls of the receiving space, the drive motor 531 can provide a certain support for the support seat 11. This helps to prevent the support seat 11 from being deformed due to the lateral force of the connecting web plate 31, thus better ensuring the stable operation of the swaying mechanism 100 and further improving the overall structural stability and reliability of the swaying mechanism 100.

[0052] Furthermore, the width of the receiving space of the support base 11 can be set to correspond to the thickness of the drive motor 531, so as to ensure that the two ends of the drive motor 531 can stably abut against the two opposite inner sidewalls of the receiving space; or, the drive motor 531 can include a motor body 5311 and a limiting block 5313. The motor body 5311 is provided with a drive wheel 5315. One end of the motor body 5311 abuts against one inner sidewall of the receiving space, and the limiting block 5313 is connected to the other end of the motor body 5311. The end of the limiting block 5313 facing away from the motor body 5311 abuts against the other opposite inner sidewall of the receiving space. By using the limiting block 5313 connected to the end of the motor body 5311, the overall thickness of the drive motor 531 can better correspond to the width of the receiving space, ensuring the stable support of the drive motor 531 on the support member 10.

[0053] See Figure 5 In one embodiment of the present invention, the support member 10 includes a first connecting column 13, a second connecting column 15, and a steering mechanism 17. The second connecting column 15 is stacked with the first connecting column 13, and the end of the second connecting column 15 facing away from the first connecting column 13 is connected to the swing member 30. The steering mechanism 17 connects the first connecting column 13 and the second connecting column 15 and drives the second connecting column 15 to rotate relative to the first connecting column 13.

[0054] The support member 10 can be formed by stacking a first connecting column 13 and a second connecting column 15. The first connecting column 13 and the second connecting column 15 can be sleeve structures with a certain cavity, so that the steering mechanism 17 can be installed in the inner cavity of the first connecting column 13 and the second connecting column 15 and connect the first connecting column 13 and the second connecting column 15. By connecting and fixing the first connecting column 13 to the bracket 200, the steering mechanism 17 can be operated by electric drive, so that the steering mechanism 17 drives the second connecting column 15 to rotate horizontally relative to the first connecting column 13, that is, the second connecting column 15 can rotate in the left and right direction. Furthermore, by connecting the end of the second connecting column 15 opposite to the first connecting column 13 to the drive assembly 50 and the swing member 30, that is, a support seat 11 can be set at the end of the second connecting column 15 opposite to the first connecting column 13, so that when the second connecting column 15 rotates, it drives the swing member 30 to rotate together, realizing the horizontal swing function of the fan 1000, so that the fan 1000 can achieve a wider range of air blowing effect, and further improving the practicality and reliability of the oscillation mechanism 100. By setting a steering mechanism 17 within the support member 10 to drive the second connecting column 15 to rotate, and causing the second connecting column 15 to drive the swing member 30 to rotate horizontally, the oscillation mechanism 100 can integrate up-and-down oscillation and horizontal oscillation functions. This allows the oscillation mechanism 100 to achieve multiple degrees of freedom of oscillation, effectively increasing the airflow range of the fan 1000, enabling the fan 1000 to better meet user needs, and further improving the practicality and reliability of the oscillation mechanism 100. Furthermore, by integrating a horizontal oscillation drive component on the support member 10 of the oscillation mechanism 100, and setting a drive assembly 50 between the support member 10 and the swing member 30 to achieve the up-and-down oscillation function, the oscillation mechanism 100 can more compactly arrange multiple drive components within a smaller volume, facilitating a more miniaturized design of the oscillation mechanism 100, thereby reducing the overall size of the fan 1000 and further improving the practicality of the oscillation mechanism 100.

[0055] In one embodiment of the present invention, the support member 10 is provided with a first limiting structure and the swing member 30 is provided with a second limiting structure. The first limiting structure and the second limiting structure can cooperate to abut against each other to limit the angle of rotation of the swing member 30 relative to the support member 10.

[0056] In this embodiment, the support member 10 may be provided with a first limiting structure on the side facing the swing member 30, for example, the first limiting structure may be provided on the side of the support base 11, and a second limiting structure may be provided on the side of the swing member 30 facing the support member 10, for example, the second limiting structure may be provided on the side of the connecting web 31. The first limiting structure and the second limiting structure may be boss structures, or may be mutually cooperating protrusion and groove structures. Of course, the first limiting structure and the second limiting structure may also adopt other cooperating and abutting structures. This application does not limit the structural form of the first limiting structure and the second limiting structure, as long as the first limiting structure and the second limiting structure can cooperate and abut when the swing member 30 rotates relative to the support member 10 at a certain angle. Furthermore, when the swing member 30 rotates at a certain angle relative to the support member 10 around the connecting shaft, the first limiting structure and the second limiting structure can abut against each other to limit the rotation angle of the swing member. This effectively prevents the swing member 30 from rotating too much relative to the support member 10, which could lead to a certain probability of collision between the components inside the swaying mechanism 100. For example, it can prevent the drive wheel 5315 of the drive assembly 50 from colliding with the end of the rack, or it can prevent the support member 10 from colliding with the swing member 30, so that the swaying mechanism 100 can achieve more stable and reliable operation.

[0057] In order to achieve a better oscillation angle for the fan 1000, the first limiting structure and the second limiting structure can abut against each other when the oscillating member 30 rotates to drive the head assembly 400 to blow air horizontally, and can abut against each other when the oscillating member 30 rotates to drive the head assembly 400 to blow air vertically upward, so that the fan 1000 can cover a larger airflow range. Of course, while satisfying the mutual avoidance of the various components of the fan 1000, the first limiting structure and the second limiting structure can abut against each other when the oscillating member 30 rotates at a larger angle, so that the fan 1000 can better meet the usage requirements. This application does not limit the rotation range of the oscillating member 30 by the first limiting structure and the second limiting structure.

[0058] This utility model also proposes a fan 1000, which includes a bracket 200, an oscillation mechanism 100 and a fan assembly 400. The specific structure of the oscillation mechanism 100 is as described in the above embodiments. Since this fan 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] 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.
