Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a swing mechanism and a device having the same. Background Art

[0002] At present in the market, most fans achieve the function of large-angle air supply by swinging up and down and left and right. A fan is disclosed in the prior art. A lining frame is fixedly connected to the machine head, and a fixing frame is fixedly connected to the machine body. The lining frame can rotate relative to the fixing frame in a vertical plane. The rotating shaft on the fixing frame is horizontally arranged. The positioning holes on the lining frame are arranged in an arc shape, and the size of the radius of the arc is the same as the size of the elastic limiting component fixedly connected to the fixing frame from the axis of the rotating shaft. So that when the user swings the lining frame up and down, the positioning hole corresponding to the elastic limiting component can be found for it to snap into to achieve the positioning effect. However, when the fan swings up and down, the angle can only be adjusted through the positioning holes at different angles. Since the positions of the positioning holes are limited, the adjustment angle is also limited, and the angle cannot be freely adjusted according to the needs of the user. Summary of the Invention

One side of the second fixing part close to the first fixing part is provided with a protruding part or a recessed part. The protruding part passes through the second connection hole and is in fit connection with the recessed part. The outer wall of the protruding part and the side walls of the first fixing part and the second fixing part cooperate to form the receiving groove.

[0015] One side of the first fixing part close to the second fixing part is provided with a limiting structure or a limiting space. One side of the second fixing part close to the first fixing part is provided with a limiting space or a limiting structure that is in fit connection with the limiting structure or the limiting space.

[0016] The limiting structure is a limiting rib, and the limiting space is a limiting hole.

[0017] The first supporting part is provided with a first connection hole. One side of the first fixing part close to the first supporting part is provided with a connection shaft that is in fit connection with the first connection hole.

[0024] The first fixing part, the second fixing part and the connection part are provided with through holes, and the through holes are arranged opposite to the first connection hole of the first supporting part and the second connection hole of the second supporting part.

[0025] A device with a shaking head mechanism includes a machine body and a machine head, and further includes the above-mentioned shaking head mechanism.

[0026] The device with a head-shaking mechanism is a fan.

[0027] The technical solution of the present invention has the following advantages:

[0028] 1. The head-shaking mechanism provided by the present invention realizes the positioning of the machine head during the head-shaking process by relying on the friction between the fixing structure and the second support part through setting a first support part fixedly connected to the fuselage of the object to be installed, a second support part fixedly connected to the machine head of the object to be installed, and a fixing structure fixedly connected to at least one side of the first support part. The fixing structure is rotatably connected to the second support part, and the friction between the fixing structure and the second support part is greater than the gravity of the machine head. That is, since there is no separate structure for positioning and adjusting the angle, when the machine head is driven to shake by an external force, the user can arbitrarily adjust the head-shaking angle of the machine head according to actual needs and realize the positioning of the machine head at any angle, so that the head-shaking angle of the head-shaking mechanism can be adjusted arbitrarily without limitation, improving the user experience.

[0029] 2. The head-shaking mechanism provided by the present invention clamps the second support part by the contact between the groove wall of the accommodating groove provided on the fixing structure and the second support part. Since the friction between the groove wall of the accommodating groove and the second support part is perpendicular to the gravity of the machine head when the machine body shakes relative to the fuselage, the friction between the groove wall of the accommodating groove and the second support part has a stronger positioning ability for the machine head.

[0030] 3. The head-shaking mechanism provided by the present invention makes the friction between the accommodating groove and the second support part greater and the positioning effect on the machine head better by setting the bottom of the accommodating groove to also contact the second support part.

[0031] 4. The head-shaking mechanism provided by the present invention can simultaneously fix both sides of the second support part by the fixing structures on both sides of the first support part when the second support part rotates relative to the first support part, making the fixing effect better.

[0032] 5. The head-shaking mechanism provided by the present invention makes the assembly of the fixing structure with the first support part and the second support part more convenient by setting the fixing structure to include a first fixing part and a second fixing part which are separately arranged.

[0033] 6. The head-shaking mechanism provided by the present invention makes the assembly of the first fixing part, the second fixing part and the second support part more compact and the overall structure of the head-shaking mechanism smaller by setting a concave part and a protruding part which are cooperatively connected on the first fixing part and the second fixing part, and setting a second connection hole on the second support part, and the protruding part passes through the second connection hole and is cooperatively connected with the concave part.

[0034] 7. The shaking head mechanism provided by the present invention makes the connection between the first fixing part and the second fixing part simpler and more convenient by providing a limiting structure and a limiting space that are cooperatively connected on the first fixing part and the second fixing part.

[0035] 8. The shaking head mechanism provided by the present invention makes the connection between the first fixing part and the first supporting part more firm by providing a positioning groove and a positioning post that are cooperatively connected on the connecting shaft of the first fixing part and the first connecting hole of the first supporting part, preventing relative rotation between the first fixing part and the first supporting part, and also enabling pre-positioning when the first fixing part and the first supporting part are assembled and fixed, thus improving the assembly efficiency.

[0036] 9. The shaking head mechanism provided by the present invention makes the assembly of the shaking head mechanism more convenient by providing a connecting part fixedly connected to the second supporting part.

[0037] 10. The shaking head mechanism provided by the present invention limits the shaking angle when the machine head rotates relative to the machine body by providing a limiting post on the first supporting part and a long hole that is cooperatively connected to the limiting post on the connecting part. When the first supporting part and the connecting part rotate relative to each other, the length of the long hole is the limit of the rotation angle.

[0038] 11. The shaking head mechanism provided by the present invention makes the long hole more adaptable to the rotation angle and makes the relative rotation between the machine head and the machine body smoother by setting the long hole as an arc-shaped hole.

[0039] 12. The shaking head mechanism provided by the present invention enables pre-positioning when the connecting part and the second supporting part are fixedly connected and prevents movement during the fixing process, thus improving the assembly efficiency, by providing a positioning convex post and a positioning hole that are cooperatively connected on the connecting part and the second supporting part.

[0040] 13. The shaking head mechanism provided by the present invention is provided with through holes on the first fixing part, the second fixing part and the connecting part, a first connecting hole on the first supporting part, and a second connecting hole on the second supporting part. Since the main motor that controls the rotation of the fan blades on the machine head is arranged on the machine head and the controller is arranged on the machine body, and the through holes, the first connecting hole and the second connecting hole are arranged opposite to each other, the control wire connecting the main motor of the fan and the controller can be passed through, and there is no need to separately open a wiring hole at other parts, making the overall structure of the shaking head mechanism relatively compact.

Detailed implementation manners

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] As Figure 1 - Figure 9 shown, in this embodiment, a shaking head mechanism is provided, including: a first support portion 1, a second support portion 2, and a fixing structure.

[0056] The first support portion 1 is adapted to be fixedly connected to the fuselage 5 of the object to be installed; the second support portion 2 is adapted to be fixedly connected to the nose of the object to be installed; the fixing structure is fixedly connected to at least one side of the first support portion 1, and the fixing structure is rotatably connected to the second support portion 2, and the frictional force between the fixing structure and the second support portion 2 is greater than the gravity of the nose.

[0057] In this embodiment, the object to be installed is a fan. By providing the first support portion 1 fixedly connected to the fuselage 5 of the fan, the second support portion 2 fixedly connected to the nose of the fan, and the fixing structure fixedly connected to at least one side of the first support portion 1, the fixing structure is rotatably connected to the second support portion 2, and the frictional force between the fixing structure and the second support portion 2 is greater than the gravity of the nose, that is, the positioning of the nose during the shaking head process is achieved by relying on the frictional force between the fixing structure and the second support portion 2. Since no separate structure for positioning and adjusting the angle is provided, when an external force drives the nose to shake, the user can arbitrarily adjust the shaking head angle of the nose according to actual needs and achieve the positioning of the nose at any angle, so that the shaking head angle of the shaking head mechanism of the fan can be adjusted arbitrarily without limitation, improving the user experience. As an alternative embodiment, it can also be that the shaking head mechanism is the shaking head mechanism of other objects to be installed that need to achieve the shaking head function.

[0058] In this embodiment, the fixing structure is fixedly connected to both sides of the first support portion 1. By providing the fixing structures on both sides of the first support portion 1, when the second support portion 2 rotates relative to the first support portion 1, the fixing structures on both sides can simultaneously fix both sides of the second support portion 2, resulting in a better fixing effect. As an alternative embodiment, it can also be that the fixing structure is only fixedly connected to one side of the first support portion 1.

[0059] Specifically, the fixed structure in this embodiment is provided with a receiving groove, and a second support portion 2 is arranged in the receiving groove. The groove wall and the groove bottom of the receiving groove are both in contact with the second support portion 2, and the groove wall of the receiving groove clamps the second support portion 2, so that the frictional force between the receiving groove and the second support portion 2 is greater than the gravity of the machine head. By providing a receiving groove for accommodating the second support portion 2 on the fixed structure, and the groove wall of the receiving groove is in contact with and clamps the second support portion 2. Since when the machine body shakes its head relative to the fuselage 5, the frictional force between the groove wall of the receiving groove and the second support portion 2 is perpendicular to the gravity of the machine head, the positioning ability of the groove wall of the receiving groove to the second support portion 2 is stronger. By setting the groove bottom of the receiving groove to also be in contact with the second support portion 2, the frictional force between the receiving groove and the second support portion 2 is greater, and the positioning effect on the machine head is better. As an alternative embodiment, it can also be that only the groove wall of the receiving groove is in contact with the second support portion 2, and the groove wall clamps the second support portion 2; or only the groove bottom of the receiving groove is in contact with the second support portion 2, and the frictional force between the groove bottom and the second support portion 2 is greater than the gravity of the machine head.

[0060] The fixed structure in this embodiment includes: a first fixing portion 3 fixedly connected to the first support portion 1; a second fixing portion 4 connected to the first fixing portion 3, and a receiving groove is formed between the second fixing portion 4 and the first fixing portion 3. By setting the fixed structure to include a separately arranged first fixing portion 3 and a second fixing portion 4, the assembly of the fixed structure with the first support portion 1 and the second support portion 2 is more convenient. As an alternative embodiment, it can also be that the fixed structure is an integrally formed structure, and a receiving groove is opened on it, and the second support portion 2 is clamped in the receiving groove.

[0061] Specifically, as Figure 2 shown, on one side of the first fixing portion 3 close to the second fixing portion 4 in this embodiment, there is a recessed portion 35, on the second support portion 2 there is a second connection hole 22, and on one side of the second fixing portion 4 close to the first fixing portion 3 there is a protruding portion 45. The protruding portion 45 passes through the second connection hole 22 and is in fit connection with the recessed portion 35, and the outer wall of the protruding portion 45 cooperates with the side walls of the first fixing portion 3 and the second fixing portion 4 to jointly form a receiving groove. By providing a recessed portion 35 and a protruding portion 45 on the first fixing portion 3 and the second fixing portion 4 for fit connection, a second connection hole 22 is provided on the second support portion 2, and the protruding portion 45 passes through the second connection hole 22 and is in fit connection with the recessed portion 35, making the assembly of the first fixing portion 3, the second fixing portion 4 and the second support portion 2 more compact, and the overall structure of the head shaking mechanism of the fan smaller. As an alternative embodiment, it can also be that a protruding portion is provided on the first fixing portion 3 and a recessed portion is provided on the second fixing portion 4.

[0062] As Figure 3 and Figure 4As shown in the figure, a limiting structure is provided on one side of the first fixing part 3 close to the second fixing part 4 in this embodiment, and a limiting hole 41 that is cooperatively connected with the limiting structure is provided on one side of the second fixing part 4 close to the first fixing part 3. Specifically, the limiting structure in this embodiment is a limiting rib 31. By providing the cooperatively connected limiting structure and limiting hole 41 on the first fixing part 3 and the second fixing part 4, the connection between the first fixing part 3 and the second fixing part 4 is made simpler and more convenient, and relative rotation between the first fixing part 3 and the second fixing part 4 is also prevented. As a variable implementation manner, it may also be that a limiting hole is provided on the first fixing part 3 and a limiting rib is provided on the second fixing part 4. As a transformable implementation manner, it may also be that the limiting hole can be replaced by a limiting groove.

[0063] To facilitate the assembly of the first support part 1 and the first fixing part 3, a first connection hole 12 is provided on the first support part 1 in this embodiment, and a connection shaft 36 that is cooperatively connected with the first connection hole 12 is provided on one side of the first fixing part 3 close to the first support part 1. A positioning column 32 is provided on the peripheral wall of the connection shaft 36, and a positioning groove 13 that is communicated with the first connection hole 12 and is cooperatively connected with the positioning column 32 is provided on the first connection hole 12. By providing the positioning column 32 on the connection shaft 36 of the first fixing part 3 and the cooperatively connected positioning groove 13 on the first connection hole 12 of the first support part 1, the connection between the first fixing part 3 and the first support part 1 is made more firm, relative rotation between the first fixing part 3 and the first support part 1 is prevented, and pre-positioning can be achieved when the first fixing part 3 and the first support part 1 are assembled and fixed, thereby improving the assembly efficiency. As a transformable implementation manner, it may also be that the positioning column 32 and the positioning groove 13 that cooperate with each other are not provided on the connection shaft 36 and the first connection hole 12. As a transformable implementation manner, it may also be that the positioning groove is replaced by a positioning hole.

[0064] A first screw hole 33 is further provided on the first fixing part 3 in this embodiment, a second screw hole 43 is further provided on the second fixing part 4, and a fifth screw hole 11 is further provided on the first support part 1. Screws are passed through the first screw hole 33, the second screw hole 43, and the fifth screw hole 11 to fixedly connect the first fixing part 3, the second fixing part 4, and the first support part 1 together.

[0065] The fixing structure in this embodiment further includes a connecting part 6, which is provided on the side of the second fixing part 4 away from the first fixing part 3, and the connecting part 6 is fixedly connected to the second support part 2. By providing the connecting part 6 fixedly connected to the second support part 2, the assembly of the shaking mechanism of the fan is made more convenient. As a transformable implementation manner, it may also be that the connecting part is not provided.

[0066] As Figure 4 and Figure 5As shown, on one side of the second fixing part 4 in this embodiment close to the connecting part 6, there are two limiting posts 42, and on the connecting part 6, there are two long slots that are cooperatively connected with the limiting posts 42. By arranging the limiting posts 42 on the second fixing part 4 and the long slots that are cooperatively connected with the limiting posts 42 on the connecting part 6, when the first support part 1 rotates relative to the connecting part 6, the positions at both ends of the long slot limit the two extreme positions during the shaking head process, that is, the length of the long slot limits the rotation angle, and further limits the shaking head angle when the machine head rotates relative to the fuselage 5. As a transformable implementation manner, it can also be that the specific number of the limiting posts 42 and the long slots is set to one or more.

[0067] Specifically, the long slot in this embodiment is an arc-shaped slot 62. By setting the long slot as the arc-shaped slot 62, the long slot is more adapted to the rotation angle, and the relative rotation between the machine head and the fuselage 5 is smoother.

[0068] For convenience of assembly, as Figure 5 and Figure 7 shown, on the connecting part 6 in this embodiment, there is a positioning convex post 63, on the second support part 2, there is a positioning hole 23 that is cooperatively connected with the positioning convex post 63, on the connecting part 6, there is a third screw hole 61, and on the second support part 2, there is a fourth screw hole 21. The screw passes through the third screw hole 61 and the fourth screw hole 21, that is, after the positioning convex post 63 and the positioning hole 23 are cooperatively connected, the connecting part 6 and the second support part 2 are fixedly connected by using screws. By arranging the positioning convex post 63 and the positioning hole 23 that are cooperatively connected on the connecting part 6 and the second support part 2, when the connecting part 6 and the second support part 2 are fixedly connected, they can be pre-positioned to prevent movement during the fixing process, and the assembly efficiency is improved. As a transformable implementation manner, it can also be that the connecting part 6 is provided with a positioning hole, and the second support part 2 is provided with a positioning convex post that is cooperatively connected with the positioning hole.

[0069] As Figure 8As shown in the figure, a first through hole 34 is provided on the first fixing part 3 in this embodiment, a second through hole 44 is provided on the second fixing part 4, a third through hole 64 is provided on the connecting part 6, and the first through hole 34, the second through hole 44, and the third through hole 64 are arranged opposite to the first connection hole 12 and the second connection hole 22. By providing the first through hole 34 on the first fixing part 3, the second through hole 44 on the second fixing part 4, the third through hole 64 on the connecting part 6, the first connection hole 12 on the first support part 1, and the second connection hole 22 on the second support part 2, since the main motor that controls the rotation of the fan blades on the head of the fan is provided on the head, and the controller is provided on the body 5, and the first through hole 34, the second through hole 44, the third through hole 64, the first connection hole 12, and the second connection hole 22 are arranged opposite to each other, the control wire connecting the main motor of the fan and the controller can be passed through, and there is no need to separately provide a wiring hole at other positions, making the overall structure of the fan's swing mechanism more compact. At the same time, since the first fixing part 3, the second fixing part 4, the first support part 1, the second support part 2, and the connecting part 6 are coaxially fixed and sleeved with each other, space is further saved and the volume of the swing mechanism is reduced.

[0070] In this embodiment, the swing mechanism of the fan can be directly fixedly connected to the second support part 2 through the rotating shaft of the motor. By driving the rotation of the second support part 2 through the rotation of the motor, the head of the fan is driven to rotate relative to the body 5. Since the direct drive method of the motor is adopted and there is no need to set up a transmission mechanism, the volume of the swing mechanism is smaller. As a changeable embodiment, it can also be that the motor drives the rotation of the second support part 2 in the form of a motor cooperating with a crank-link mechanism or a motor cooperating with a gear mechanism.

[0071] This embodiment also provides a device with a swing mechanism, which includes a body 5 and a head, and also includes the swing mechanism as described above.

[0072] The device with a swing mechanism in this embodiment is a fan. As a changeable embodiment, it can also be that the device with a swing mechanism is other devices that need to realize the swing function.

[0073] By providing the above swing mechanism, the head of the fan can swing up and down or left and right relative to the body 5. During installation, when the rotating shaft of the motor is parallel to the ground, the head of the fan can swing up and down relative to the body 5, and when the rotating shaft of the motor is perpendicular to the ground, the head of the fan can swing left and right relative to the body 5. And because the above swing mechanism is provided, the user can also arbitrarily adjust the swing angle of the fan according to actual needs and position it through friction, without the need to separately set a positioning structure, making the overall volume of the swing mechanism smaller and improving the user experience.

[0074] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
