[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1 to Figure 2As shown, an embodiment of the present application provides a swing assembly, which includes: a support 10, a left cover plate 20, a right cover plate 30, a first rotating member 41, a second rotating member 42 and an elastic member. Among them, the support 10 has a first connecting portion 11 and a second connecting portion 12, and the support 10 is used to connect with the support rod on the fan. The left cover plate 20 is rotatably arranged on the first connecting portion 11, and the right cover plate 30 is rotatably arranged on the second connecting portion 12. There is a connecting structure between the left cover plate 20 and the right cover plate 30, and the left cover plate 20 and the right cover plate 30 are used to connect with the head assembly on the fan, so that the left cover plate 20 and the right cover plate 30 swing relative to the support 10 to realize the swing of the head assembly relative to the support rod. The first rotating member 41 and the second rotating member 42 are located between the left cover plate 20 and the first connecting portion 11, and the first rotating member 41 is fixedly connected to the left cover plate 20, and the second rotating member 42 is fixedly connected to the first connecting portion 11. The first rotating member 41 and the second rotating member 42 have a separation state and a connection state that are relatively arranged. When the first rotating member 41 and the second rotating member 42 are in the separation state, the first rotating member 41 can rotate relative to the second rotating member 42, so that the left cover plate 20 can be rotated relative to the support 10. When the first rotating member 41 and the second rotating member 42 are in the connection state, the first rotating member 41 and the second rotating member 42 are relatively fixed, so that the left cover plate 20 can be fixed relative to the support 10. The elastic member is arranged between the left cover plate 20 and the first connecting portion 11, and / or the elastic member is arranged between the right cover plate 30 and the second connecting portion 12, and the elastic member can provide elastic pre-tightening force to the first rotating member 41 and the second rotating member 42, so that the first rotating member 41 and the second rotating member 42 remain in the connection state. By providing the elastic member, the stability of the first rotating member 41 and the second rotating member 42 when being fixed can be further improved, thereby improving the stability of the left cover plate 20 when being fixed relative to the support 10.

[0038] When in use, the first rotating member 41 and the second rotating member 42 are in a separated state, so that the swing angle of the left cover plate 20 and the right cover plate 30 relative to the support 10 can be adjusted, and then the pitch angle of the head assembly on the support rod can be completed. When the angle adjustment is completed, the first rotating member 41 and the second rotating member 42 are in a connected state, so that the left cover plate 20 and the right cover plate 30 can be fixed relative to the support 10 to stabilize the head assembly on the support rod. The above structure can realize the adjustment of the head assembly in the pitch direction relative to the support rod.

[0039] According to the technical solution provided by the present application, the swing assembly includes a support 10, a left cover plate 20, a right cover plate 30, a first rotating member 41, a second rotating member 42 and an elastic member. The first rotating member 41 and the second rotating member 42 are arranged between the left cover plate 20 and the first connecting portion 11, and the first rotating member 41 and the second rotating member 42 cooperate to realize the swing and fixation of the left cover plate 20 relative to the support 10, so as to replace the swing adjustment method of the prior art by the rubber spring, and the first rotating member 41 and the second rotating member 42 are used for swing and fixation, and the structure is more stable and not easy to deform, which can ensure the stability of the swing of the left cover plate and the right cover plate relative to the support, and extend the service life of the device as a whole. The elastic member is used in the present application to provide elastic preload to the first rotating member 41 and the second rotating member 42, which can further improve the stability of the first rotating member 41 and the second rotating member 42 in the connected state.

[0040] Among them, the elastic member can be only arranged between the left cover plate 20 and the first connecting part 11, or only arranged between the right cover plate 30 and the second connecting part 12, or elastic members can be arranged between the left cover plate 20 and the first connecting part 11 and between the right cover plate 30 and the second connecting part 12, as long as it can provide elastic force to the first rotating member 41 and the second rotating member 42.

[0041] like Figure 1 and Figure 3 As shown, the elastic member includes a first elastic member 51, the first connecting portion 11 has a first mounting hole 111, the second rotating member 42 and the first elastic member 51 are both located in the first mounting hole 111, the first elastic member 51 is located on the side of the second rotating member 42 away from the first rotating member 41, and one end of the first elastic member 51 abuts against the first rotating member 41, and the other end of the first elastic member 51 abuts against the inner wall of the first mounting hole 111. Through the above structure, the first elastic member 51 provides an axial elastic force to the second rotating member 42 by directly abutting against the second rotating member 42, so as to further improve the stability of the first rotating member 41 and the second rotating member 42 in the connected state. In addition, in the above structure, when the left cover plate 20 and the first rotating member 41 rotate relative to the support 10, they will not directly contact with the first elastic member 51, so that the wear on the first elastic member 51 can be avoided or reduced, and the service life of the first elastic member 51 can be extended. Among them, the first elastic member 51 can be set as a rubber spring.

[0042] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the swing assembly further includes a cover 60, the right cover plate 30 has a connection end 31, the cover 60 is fixedly connected to the connection end 31, the elastic member includes a second elastic member 52, one end of the second elastic member 52 abuts against the cover 60, and the other end of the second elastic member 52 abuts against the connection end 31, the second connecting portion 12 has a second mounting hole 121, the cover 60 extends into the second mounting hole 121, and the side of the cover 60 away from the connection end 31 abuts against one end of the second mounting hole 121, and the connection end 31 extends into the second mounting hole 121 from the other end of the second mounting hole 121. Through the above structure, the second elastic member 52 is used to provide an axial elastic force to the right cover plate 30. Since the right cover plate 30 and the left cover plate 20 are connected to each other, the elastic force provided by the second elastic member 52 to the right cover plate 30 can be transmitted to the left cover plate 20, and can further provide an elastic force to the first rotating member 41 and the second rotating member 42. Specifically, in order to better transmit the elastic force of the second elastic member 52, the first mounting hole 111 and the second mounting hole 121 may be coaxially arranged. The second elastic member 52 may be arranged as a rubber spring.

[0043] In this embodiment, the second elastic member 52 is arranged between the cover 60 and the right cover plate 30. The second elastic member 52 can rotate synchronously with the cover 60 and the right cover plate 30. This can avoid or reduce the wear of the second elastic member 52 due to the rotation of the right cover plate 30, thereby extending the service life of the second elastic member 52.

[0044] Specifically, the support 10 further includes a connecting tube 13, the connecting tube 13 has a through hole 131, the first connecting portion 11 and the second connecting portion 12 are arranged at intervals, and the first connecting portion 11 and the second connecting portion 12 are both arranged at one end of the connecting tube 13, and the first mounting hole 111 and the second mounting hole 121 are both connected to the through hole 131. Through the above structure, since the left cover plate 20 and the right cover plate 30 are not directly connected in the support 10, they will not interfere with the circuit in the through hole 131, and the circuit can be easily entered from the through hole 131 into the first mounting hole 111 and the second mounting hole 121, which is convenient for wiring.

[0045] Among them, the end surface of the connection end 31 of the right cover plate 30 is provided with a first wiring hole 32, and the cover 60 is provided with a second wiring hole 61. The first wiring hole 32, the second wiring hole 61 and the second mounting hole 121 are connected to each other. The end surface of the cover 60 close to the right cover plate 30 is provided with a protrusion 62, and the end surface of the connection end 31 of the right cover plate 30 is provided with a slot 33. The protrusion 62 is plugged and matched with the slot 33 to connect the right cover plate 30 and the cover 60. Through the above structure, it is convenient for the line routing through hole 131 to enter the first wiring hole 32 of the right cover plate 30, and the right cover plate 30 and the cover 60 are plugged and matched with the slot 33 through the protrusion 62. The structure is simple and easy to process and disassemble.

[0046] A limiting structure is provided between the left cover plate 20 and the first connecting portion 11 , and the limiting structure can limit the axial position of the left cover plate 20 in the first mounting hole 111 , so that the left cover plate 20 is stabilized in the first mounting hole 111 .

[0047] like Figure 4 and Figure 7 As shown, the limiting structure includes a limiting column 21 and a limiting piece 70, the limiting column 21 is arranged on the left cover plate 20, the limiting column 21 is inserted into the first mounting hole 111, the limiting column 21 is provided with a limiting slot 211, the limiting piece 70 has a limiting hole 71, the limiting piece 70 is inserted into the limiting slot 211 through the limiting hole 71, and the limiting piece 70 cooperates with the limiting slot 211 through the limiting hole 71 to limit the axial displacement of the limiting column 21. Through the above scheme, the axial displacement of the left cover plate 20 in the first mounting hole 111 can be limited to prevent the left cover plate 20 from coming out of the first mounting hole 111.

[0048] Specifically, the limiting hole 71 has an avoidance section and a limiting section that are interconnected. The avoidance section and the limiting section are arranged along the radial direction of the limiting hole 71. The opening size of the avoidance section is larger than the opening size of the limiting section. The opening size of the limiting section is smaller than the diameter of the limiting groove 211 of the limiting column 21. In this way, the elasticity of the limiting plate 70 can be utilized to clamp the limiting hole 71 in the limiting groove 211 to play a limiting role on the left cover 20.

[0049] The limiting piece 70 is arranged in the interval between the first connection part 11 and the second connection part 12, and an annular side wall 72 is arranged on the side of the limiting piece 70 away from the first connection part 11, and a wiring cavity is formed inside the annular side wall 72, and the wiring cavity is respectively connected to the through hole 131 and the second mounting hole 121. Through the above arrangement, the annular side wall 72 can be used to shield the line to prevent the line from being exposed to the outside, and the line can be protected.

[0050] like Figure 1 , Figure 8 and Fig. 9As shown, the first rotating member 41 is provided with a fixing portion 411, and the fixing portion 411 is fixedly connected to the left cover plate 20 so that the first rotating member 41 and the left cover plate 20 rotate synchronously. A plurality of positioning grooves 412 are provided on the side of the first rotating member 41 away from the left cover plate 20, and the plurality of positioning grooves 412 are arranged on the first rotating member 41 at annular intervals of the rotation center of the first rotating member 41. A stopper 421 is provided on the second rotating member 42, and a stopper groove is correspondingly provided on the first connecting portion 11, and the stopper 421 is correspondingly arranged in the stopper groove, so that the second rotating member 42 can be prevented from rotating relative to the first connecting portion 11. Specifically, the stopper groove can be provided on the inner wall of the first mounting hole 111. A plurality of positioning protrusions 422 are provided on the side of the second rotating member 42 close to the first rotating member 41, and the plurality of positioning protrusions 422 are arranged one-to-one correspondingly with the plurality of positioning grooves 412. Through the above structure, when the positioning protrusion 422 is located in the positioning groove 412, the first rotating member 41 and the second rotating member 42 are in a connected state. When the left cover 20 is rotated by an external force, the positioning protrusion 422 moves out of the initial positioning groove 412. At this time, there is an axial displacement between the first rotating member 41 and the second rotating member 42, and the displacement can be achieved by the second rotating member 42 squeezing the first elastic member 51 and the second elastic member 52. When the positioning protrusion 422 rotates to the preset positioning groove 412, the adjustment of the left cover 20 relative to the support 10 is completed. At this time, the first elastic member 51 and the second elastic member 52 can provide axial elastic force to the first rotating member 41 and the second rotating member 42, so that the positioning protrusion 422 remains in the positioning groove 412.

[0051] By means of the cooperation of the positioning protrusion 422 and the positioning groove 412, the first rotating member 41 and the second rotating member 42 can be rotated and fixed, and then the left cover plate 20 and the right cover plate 30 can be rotated and fixed relative to the support 10. This solution has a simple structure and, compared with the existing solution, has higher wear resistance and better stability, which prolongs the service life of the device and improves the user experience.

[0052] like Fig.10 As shown, the left cover plate 20 is provided with a first extension end 22, the right cover plate 30 is provided with a second extension end 34, the first extension end 22 is provided with a buckle 221, the second extension end 34 is provided with a slot 341 corresponding to the buckle 221, and the buckle 221 and the slot 341 are engaged with each other to form a connection structure. The left cover plate 20 and the right cover plate 30 are connected by engaging the buckle 221 and the slot 341, which has a simple structure and is easy to process and install.

[0053] The swing assembly provided by the present application uses the first rotating member 41 and the second rotating member 42 to achieve rotation and fixation. The structure is simple and the stability is high, which solves the problem that the rubber spring in the existing solution is easily worn and fails after multiple compression and friction, thereby causing the problem of being unable to position. In addition, the left cover plate 20 and the right cover plate 30 are arranged at intervals in the support 10, which can facilitate electrical wiring, so that the terminal can pass through the support 10 smoothly, simplifying the line arrangement.

[0054] The embodiment of the present application provides a fan, which includes a head assembly, a support rod and a swing assembly, wherein the swing assembly is the swing assembly provided in the above embodiment, the head assembly is respectively connected to the left cover plate 20 and the right cover plate 30 of the swing assembly, and the support rod is connected to the support 10 of the swing assembly. Specifically, the fan is a folding fan.
