[0015] The fixing structure includes:

[0016] The first fixing part is fixedly connected to the first support part;

[0017] The second fixing part is connected to the first fixing part, and a receiving groove is formed between the second fixing part and the first fixing part, and the second supporting part is sandwiched in the receiving groove.

[0018] The first fixing part has a recess or protrusion on the side near the second fixing part, the second support part has a second connecting hole, the second fixing part has a protrusion or recess on the side near the first fixing part, the protrusion passes through the second connecting hole and is connected to the recess, and the outer wall of the protrusion and the side walls of the first fixing part and the second fixing part cooperate to form the receiving groove.

[0019] The first fixing part is provided with a limiting structure or limiting space on the side near the second fixing part, and the second fixing part is provided with a limiting space or limiting structure that cooperates and connects with the limiting structure or limiting space on the side near the first fixing part.

[0021] The first support portion is provided with a first connecting hole, and the first fixing portion is provided with a connecting shaft that mates with the first connecting hole on the side near the first support portion.

[0022] The connecting shaft is provided with a positioning post or positioning groove, and the first connecting hole is provided with a positioning groove or positioning post that cooperates with the positioning post or positioning groove.

[0023] It also includes a gasket, which is fixedly connected to the first support and disposed between the power device and the first support.

[0024] A device with a swaying mechanism includes a body and a head, and also includes the aforementioned swaying mechanism.

[0025] The device with the oscillating mechanism is a fan.

[0026] The technical solution of this invention has the following advantages:

[0027] 1. The oscillation mechanism provided by the present invention is disposed on an object to be installed, such as an oscillation mechanism on a fan. It consists of a first support part fixedly connected to the fan body, a second support part fixedly connected to the fan head, and a power device. The power device body is fixedly connected to one of the first and second support parts, and the output shaft of the power device is fixedly connected to the other of the first and second support parts. When the output shaft of the power device rotates relative to the body, the second support part rotates relative to the first support part. In other words, the fan head can rotate relative to the body by the relative rotation between the output shaft of the power device and the body, without the need for a transmission mechanism. This results in fewer parts and a smaller overall size for the oscillation mechanism.

[0028] 2. The oscillating mechanism provided by the present invention simplifies the structure of the power device by setting the power device as a motor, and the output shaft of the power device is the rotating shaft of the motor. The oscillating mechanism can realize the rotation of the machine head relative to the machine body by directly driving the motor.

[0029] 3. The oscillating mechanism provided by the present invention is convenient to assemble by setting a connecting part that is fixedly connected to the second support part and fixedly connected to the output shaft.

[0030] 4. The swaying mechanism provided by the present invention provides a limiting post on the first support part and an elongated hole on the connecting part that cooperates with the limiting post, so that when the first support part and the connecting part rotate relative to each other, the length of the elongated hole is the limit of the rotation angle, thereby limiting the swaying angle when the machine head rotates relative to the machine body.

[0031] 5. The oscillating mechanism provided by the present invention, by setting the elongated hole as an arc-shaped hole, makes the elongated hole more compatible with the rotation angle, and makes the relative rotation of the machine head and the machine body smoother.

[0032] 6. The swaying mechanism provided by the present invention, by providing positioning protrusions and positioning holes that cooperate with each other on the connecting part and the second support part, enables the connecting part and the second support part to be pre-positioned when fixedly connected, preventing movement during the fixing process and improving assembly efficiency.

[0033] 7. The swaying mechanism provided by the present invention, by setting a fixed structure, is fixedly connected to at least one side of the first support and rotatably connected to the second support, so that the fixed structure can play a better positioning role when the second support rotates relative to the first support.

[0034] 8. The swaying mechanism provided by the present invention, by setting the fixing structure to include a first fixing part and a second fixing part that are separately arranged, makes it easier to assemble the fixing structure with the first support part and the second support part. By forming an accommodating groove between the first fixing part and the second fixing part to clamp the second support part, the fixing structure can better position the second support part during rotation.

[0035] 9. The swaying mechanism provided by the present invention, by providing a recessed portion and a protrusion that are connected to each other on the first fixing portion and the second fixing portion, and providing a second connecting hole on the second support portion, with the protrusion passing through the second connecting hole and connecting with the recessed portion, makes the assembly of the first fixing portion, the second fixing portion and the second support portion more compact and the overall structure of the swaying mechanism smaller.

[0036] 10. The swaying mechanism provided by the present invention, by providing a limiting structure and a limiting space that are connected in cooperation on the first fixed part and the second fixed part, makes the connection between the first fixed part and the second fixed part simpler and more convenient, and also prevents relative rotation between the first fixed part and the second fixed part.

[0037] 11. The swaying mechanism provided by the present invention provides a positioning groove and a positioning post that are provided in a matching connection on the connecting shaft of the first fixed part and the first connecting hole of the first support part, which makes the connection between the first fixed part and the first support part more secure, prevents relative rotation between the first fixed part and the first support part, and also enables the first fixed part and the first support part to be pre-positioned when assembled and fixed, thereby improving assembly efficiency.

Detailed Implementation

[0051] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] like Figure 1 - Figure 10 As shown, this embodiment provides a head-shaking mechanism, including: a first support part 13, a second support part 6, and a power device.

[0054] The first support part 13 is adapted to be fixedly connected to the body 1 of the object to be installed; the second support part 6 is adapted to be fixedly connected to the head of the object to be installed; the power unit includes a body 53 and an output shaft provided on the body 53, the body 53 is fixedly connected to one of the first support part 13 and the second support part 6, the output shaft is fixedly connected to the other of the first support part 13 and the second support part 6, and the output shaft rotates relative to the body 53, causing the second support part 6 to rotate relative to the first support part 13.

[0055] In this embodiment, the oscillation mechanism is an oscillation mechanism mounted on a fan. It consists of a first support portion 13 fixedly connected to the fan body 1, a second support portion 6 fixedly connected to the fan head, and a power unit. The power unit body 53 is fixedly connected to one of the first support portion 13 and the second support portion 6, and the output shaft of the power unit is fixedly connected to the other of the first support portion 13 and the second support portion 6. When the output shaft of the power unit rotates relative to the body 53, the second support portion 6 rotates relative to the first support portion 13. In other words, the fan head rotates relative to the body 1 simply by the relative rotation between the output shaft of the power unit and the body 53, without the need for a transmission mechanism. This results in fewer components and a smaller overall size for the fan's oscillation mechanism. Alternatively, the oscillation mechanism can be any other oscillation mechanism required for any installation object that needs to achieve oscillation functionality.

[0056] Specifically, in this embodiment, the power unit body 53 is fixedly connected to the first support part 13, and the output shaft is fixedly connected to the second support part 6. The output shaft of the power unit drives the second support part 6 to rotate, thereby driving the machine head to rotate. As an alternative implementation, the power unit body 53 can also be fixedly connected to the second support part 6, and the output shaft can be fixedly connected to the first support part 13. Since the power unit body 53 and the output shaft rotate relative to each other, when the output shaft is fixedly connected to the first support part 13 which is fixedly connected to the machine body 1, the machine body 1 remains stationary, which is equivalent to the power unit body 53 rotating, thereby causing the second support part 6, which is fixedly connected to the body 53, to rotate, that is, the machine head rotates relative to the machine body 1.

[0057] like Figure 4 As shown, in this embodiment, the power device is a motor 5, the output shaft is the rotating shaft 52 of the motor 5, and the body 53 of the motor 5 is provided with a fourth screw hole 51. Screws are inserted through the fourth screw hole 51 to fix the body 53 of the motor 5 to the first support part 13. By setting the power device as a motor 5, and the output shaft of the power device being the rotating shaft 52 of the motor 5, the structure of the power device is simplified. The fan oscillation mechanism is directly driven by the motor 5, which can realize the rotation of the fan head relative to the body 1 without the need for a transmission mechanism, making the overall size of the fan oscillation mechanism smaller.

[0058] The oscillation mechanism in this embodiment also includes a connecting part 4, which is fixedly connected to the second support part 6 and to the output shaft. By providing the connecting part 4, which is fixedly connected to the second support part 6 and to the output shaft, the oscillation mechanism of the fan is easier to assemble. As an alternative implementation, the connecting part 4 may be omitted, and a component fixedly connected to the output shaft may be provided on the second support part 6.

[0059] For ease of assembly, such as Figure 3 and Figure 5 As shown, in this embodiment, the connecting part 4 is provided with a positioning protrusion 43, the second support part 6 is provided with a positioning hole 63 that mates with the positioning protrusion 43, the connecting part 4 is provided with a third screw hole 41, and the second support part 6 is provided with a fifth screw hole 61. Screws are inserted into the third screw hole 41 and the fifth screw hole 61, meaning that the positioning protrusion 43 is connected to the positioning hole 63 before the screws are used to fix the connecting part 4 and the second support part 6. By providing the mutually engaging positioning protrusion 43 and positioning hole 63 on the connecting part 4 and the second support part 6, the connecting part 4 and the second support part 6 can be pre-positioned during the fixing process, preventing movement and improving assembly efficiency. Alternatively, the connecting part 4 may be provided with a positioning hole, and the second support part 6 may be provided with a positioning protrusion that mates with the positioning hole.

[0060] In this embodiment, the first support part 13 is provided with a first connecting hole 12, the second support part 6 is provided with a second connecting hole 62 opposite to the first connecting hole 12, the connecting part 4 is provided with a protrusion, and the protrusion is provided with a mating hole 44. The output shaft of the power device passes through the first connecting hole 12 and the second connecting hole 62 and is mated with the mating hole 44 on the connecting part 4.

[0061] The swaying mechanism in this embodiment also includes a fixing structure, which is fixedly connected to one side of the first support portion 13 and rotatably connected to the second support portion 6. By providing the fixing structure, which is fixedly connected to at least one side of the first support portion 13 and rotatably connected to the second support portion 6, the fixing structure can play a better positioning role when the second support portion 6 rotates relative to the first support portion 13. As an alternative implementation, fixing structures can also be provided on both sides of the first support portion 13.

[0062] The fixing structure in this embodiment includes: a first fixing part 3, fixedly connected to the first support part 13; and a second fixing part 2, connected to the first fixing part 3, with a receiving groove formed between the second fixing part 2 and the first fixing part 3, and the second support part 6 sandwiched within the receiving groove. By setting the fixing structure to include a first fixing part 3 and a second fixing part 2 that are separately configured, the assembly of the fixing structure with the first support part 13 and the second support part 6 is more convenient. The receiving groove formed between the first fixing part 3 and the second fixing part 2, which sandwiches the second support part 6, allows the fixing structure to better position the second support part 6 during rotation. Alternatively, the fixing structure can be a one-piece molded structure with a receiving groove formed thereon, and the second support part 6 sandwiched within the receiving groove. Alternatively, the fixing structure can be of other forms to position the rotating second support part 6.

[0063] Specifically, such as Figure 6 As shown, in this embodiment, the first fixing part 3 has a recess 34 on the side near the second fixing part 2, the second support part 6 has a second connecting hole 62, and the second fixing part 2 has a protrusion 25 on the side near the first fixing part 3. The protrusion 25 passes through the second connecting hole 62 and engages with the recess 34. The outer wall of the protrusion 25 and the side walls of the first fixing part 3 and the second fixing part 2 cooperate to form a receiving groove. By providing the recess 34 and the protrusion 25 that engage with the first fixing part 3 and the second fixing part 2, and by providing the second connecting hole 62 on the second support part 6, with the protrusion 25 passing through the second connecting hole 62 and engaging with the recess 34, the assembly of the first fixing part 3, the second fixing part 2, and the second support part 6 becomes more compact, and the overall structure of the fan's oscillation mechanism becomes smaller. As an alternative implementation, the first fixing part 3 may have a protrusion, and the second fixing part 2 may have a recess.

[0064] In this embodiment, the fixing structure utilizes the fact that the friction between the receiving groove and the second support part 6 is greater than the weight of the machine head fixedly connected to the second support part 6, thus achieving positioning during its rotation. No other auxiliary positioning structures are required, resulting in a simpler structure. Alternatively, the fixing structure and the second support part 6 can be equipped with mutually engaging elastic protrusions and positioning holes to achieve positioning of the rotation angle.

[0065] like Figure 7 and Figure 8As shown, in this embodiment, the first fixing part 3 has a limiting structure on the side near the second fixing part 2, and the second fixing part 2 has a limiting hole 21 that mates with the limiting structure on the side near the first fixing part 3. Specifically, the limiting structure in this embodiment is a limiting rib 31. By providing a matching limiting structure and a limiting hole 21 on the first fixing part 3 and the second fixing part 2, the connection between the first fixing part 3 and the second fixing part 2 is made simpler and more convenient, and relative rotation between the first fixing part 3 and the second fixing part 2 is prevented. As a variable implementation, the first fixing part 3 may have a limiting hole, and the second fixing part 2 may have a limiting rib. As a variable implementation, the limiting hole may be replaced by a limiting groove.

[0066] To facilitate the assembly of the first support part 13 and the first fixing part 3, such as Figure 2 and Figure 6 As shown, in this embodiment, the first support portion 13 is provided with a first connecting hole 12, and the first fixing portion 3 is provided with a connecting shaft 36 that mates with the first connecting hole 12 on the side near the first support portion 13. A positioning post 32 is provided on the peripheral wall of the connecting shaft 36, and a positioning groove 14 that communicates with the first connecting hole 12 and mates with the positioning post 32 is provided on the first connecting hole 12. By providing a positioning post 32 on the connecting shaft 36 of the first fixing portion 3 and a mate-connecting positioning groove 14 on the first connecting hole 12 of the first support portion 13, the connection between the first fixing portion 3 and the first support portion 13 is made more secure, preventing relative rotation between the first fixing portion 3 and the first support portion 13, and also enabling pre-positioning during assembly and fixing of the first fixing portion 3 and the first support portion 13, thus improving assembly efficiency. Alternatively, in an alternative embodiment, the mate-connecting post 32 and positioning groove 14 may not be provided on the connecting shaft 36 and the first connecting hole 12. Alternatively, the positioning groove 14 may be replaced by a positioning hole.

[0067] like Figure 5 and Figure 8As shown, in this embodiment, the first support part 13 is provided with two limiting posts 22 on the side near the connecting part 4 via a second fixing part 2 that is fixedly connected to it. The connecting part 4 is provided with two elongated holes that cooperate with the limiting posts 22. By providing limiting posts 22 on the second fixing part 2 and elongated holes that cooperate with the limiting posts 22 on the connecting part 4, when the first support part 13 and the connecting part 4 rotate relative to each other, the positions of the two ends of the elongated holes limit the two extreme positions during the oscillation process. That is, the length of the elongated holes limits the rotation angle, thereby limiting the oscillation angle when the machine head rotates relative to the machine body 1. As an alternative implementation, the specific number of limiting posts 22 and elongated holes can be set to one or more. As an alternative implementation, the fixing structure can also be omitted, and limiting posts can be provided on the side of the first support part 13 near the connecting part 4.

[0068] Specifically, in this embodiment, the elongated hole is an arc-shaped hole 42. By setting the elongated hole as an arc-shaped hole 42, the elongated hole is better adapted to the rotation angle, and the relative rotation between the machine head and the machine body 1 is smoother.

[0069] In this embodiment, the first fixing part 3 is also provided with a first screw hole 33, the second fixing part 2 is also provided with a second screw hole 23, and the first support part 13 is also provided with a sixth screw hole 11. Screws are inserted into the first screw hole 33, the second screw hole 23 and the sixth screw hole 11 to fix the first fixing part 3, the second fixing part 2 and the first support part 13 together.

[0070] like Figure 1 As shown, in this embodiment, the first fixing part 3 is provided with a first through hole 35, and the second fixing part 2 is provided with a second through hole 24. The first through hole 35 and the second through hole 24 are arranged opposite to the first connecting hole 12 and the second connecting hole 62. The connecting part 4 is provided with a protrusion, and the protrusion is provided with a mating hole 44. The output shaft of the power device passes through the through hole, the first connecting hole 12 and the second connecting hole 62 and is fixedly connected to the mating hole 44 on the connecting part 4. Since the first fixing part 3, the second fixing part 2, the first support part 13, the second support part 6 and the connecting part 4 are coaxially fixed with the motor 5 and are nested together, space is further saved and the volume of the oscillating mechanism is reduced.

[0071] like Figure 9 As shown, the fan oscillation mechanism in this embodiment also includes a pad 7, which is fixedly connected to the first support part 13 and located between the motor 5 and the first support part 13. This prevents the screw from touching the motor 5 after passing through the screw hole on the first support part 13, thus preventing damage to the motor 5 and providing better protection for the motor 5.

[0072] This embodiment also provides a device with a head-shaking mechanism, including a body 1 and a head, and also includes the head-shaking mechanism as described above.

[0073] In this embodiment, the device with the oscillation mechanism is a fan. As an alternative implementation, the device with the oscillation mechanism can also be any other device that needs to achieve the oscillation function.

[0074] By setting the aforementioned oscillation mechanism, the fan head can oscillate up and down or left and right relative to the body 1. During installation, when the shaft 52 of the motor 5 is parallel to the ground, the fan head can oscillate up and down relative to the body 1; when the shaft 52 of the motor 5 is perpendicular to the ground, the fan head can oscillate left and right relative to the body 1. Furthermore, the oscillation mechanism also reduces the overall size of the fan, thus reducing the space occupied by the fan and allowing other parts of the fan to be used for other purposes. This also improves the fan's assembly efficiency.

[0075] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
