Description

[Technical Field]

[0001] The present application relates to the technical field of rotating assemblies, and more particularly to a rotating assembly with damping and a folding fan. [Background technology]

[0002] Existing rotating assemblies typically incorporate a damping structure between two rotating members to limit sudden rotation between them. However, existing damping structures typically require installation on the rotating joints or the rotating shaft on both sides of the rotating members. For example, the solution disclosed in Chinese Patent CN210889408U involves installing multiple silicon members in the rotating grooves on both sides of a base, allowing the rotating shaft of the rotating rod to rotate with damping relative to the rotating grooves. In this method, the silicon members are independent damping members and typically require attachment to two joints, making installation of the silicon members on the rotating members more complicated and preventing them from being attached and detached as independent members. Furthermore, silicon members cannot accurately position the rotation angle, and after a period of use, they typically wear out, leading to inaccurate positioning and even malfunction.

[0003] For this reason, the prior art requires a damped rotation assembly that simplifies the mounting method of the damping member and improves the positioning accuracy of the rotation angle. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0020] In order to make the objectives, technical solutions and advantages of the present application clearer, the following detailed description of the embodiments of the present application is given with reference to the accompanying drawings. It should be noted that, unless mutually contradictory, the embodiments and features of the embodiments of the present application can be arbitrarily combined.

[0021] As shown in FIGS. 4 and 5 , the damped rotating assembly according to the present application is used to realize support between two rotating members and damped rotation and positioning. Specifically, it can be applied to various household electrical appliances, such as electric fans, lamps, or small solar heaters. The rotating assembly includes a base 1 and a support member 4, with the support member 4 rotatably mounted on the base 1. Specifically, one side of the support member 4 is rotatably connected to the base 1 via a rotation shaft 42, and the other side of the support member 4 is rotatably connected to the base 1 via a damping member 6. The damping member 6 can have a modular, integrated structure, which facilitates installation. In the present application, one side of the support member 4 is rotatably connected to the base 1 via the rotation shaft 42, and the other side of the support member 4 is rotatably connected to the base 1 via the damping member 6. Compared to a system in which both ends of the support member are provided with rotation shafts and rotatably connected to the base via a damping structure, the present application simplifies the connection structure between the base 1 and the support member 4. At the same time, since the damping member 6 has an integral structure, it can be attached between the support member 4 and the base 1, making it easy to attach, detach and maintain, and the overall structure is compact. Furthermore, the damping member 6 has a certain limiting function in this application.

[0022] As shown in FIGS. 6 to 9 , in some embodiments, the damping member 6 includes a first connecting portion 61 and a second connecting portion 62 that are rotatable relative to each other. Specifically, when the force between the first connecting portion 61 and the second connecting portion 62 reaches a predetermined value, the first connecting portion 61 and the second connecting portion 62 are rotatable relative to each other, thereby realizing resisted rotation, which may be realized by a friction structure or an elastic structure. The first connecting portion 61 may be bonded to the support member 4, and the second connecting portion 62 may be bonded to the base 1, thereby realizing resisted rotation between the support member 4 and the base 1. It should be noted that the first connecting portion 61 and the second connecting portion 62 may be fixedly or detachably installed on the support member 4 or the base 1, respectively.

[0023] As shown in FIGS. 6 to 9, in some embodiments, a connection sheet 63 may be integrally formed with the first connection portion 61 to facilitate connection. The second connection portion 62 may be detachably connected to the base 1, specifically, may be inserted therein, which makes installation easier. By adopting the above design, the connection sheet 63 can be fixed to the support member 4 and rotate together with the support member 4. Specifically, the connection sheet 63 may have mounting holes, allowing the connection sheet 63 to be fixed to the support member 4 with screws, improving installation reliability.

[0024] As shown in Figures 4 to 5 and 10 to 12, in some embodiments, a separate and independent limiting assembly may be provided between the support member 4 and the base 1. The limiting assembly may be an elastic assembly, which is used to adjust the rotation angle between the support member 4 and the base 1, thereby realizing a more accurate position limit. In the present application, the damping member 6 and the limiting assembly may be installed on both sides of the support member 4, respectively, which improves the balance of the damping structures on both sides of the support member 4 and makes the rotation process smoother.

[0025] 4 to 5 and 11 to 15, in some embodiments, a rotary shaft bracket 12 is provided in the base 1, a connecting groove 122 is provided in the rotary shaft bracket 12, and the rotary shaft 42 on one side of the support member 4 is rotatably installed in the connecting groove 122 and is rotatable around the connecting groove 122. Furthermore, a limiting assembly may be installed between the rotary shaft bracket 12 and the support member 4, thereby allowing the support member 4 to rotate on the rotary shaft bracket 12 up to a predetermined angle, thereby achieving angle adjustment.

[0026] As shown in FIGS. 10 to 15 , in some embodiments, a spring mounting hole 43 is provided on one side of the support member 4. A connecting plate 11 is provided on the rotation axis bracket 12, and multiple limiting holes 111 are provided on the connecting plate 11 corresponding to different predetermined angles. Preferably, as shown in FIGS. 11 and 12 , four limiting holes 111 are provided, corresponding to angles between the support member 4 and the base 1 of 0°, 30°, 60°, and 90°, respectively. Specifically, the limiting assembly may include a spring 9 and a blocking member 10, and the spring 9 is installed in the spring mounting hole 43. A portion of the blocking member 10 abuts against the spring 9, and other portions of the blocking member 10 are movably installed in each limiting hole 111. The blocking member 10 may be a steel ball. By using the above structure, when the rotational force applied to the support member 4 reaches a predetermined value, the blocking member 10 can slide to the next limiting hole 111 against the spring force of the spring 9, thereby adjusting the rotation angle between the support member 4 and the base 1. During the sliding process, the fitting of the blocking member 10 with the restricting hole 111 generates a sound, which serves as a warning.

[0027] As shown in FIGS. 4-5 and 13-15, in some embodiments, a support plate 7 is further provided within the base 1, and a rotating shaft bracket 12 is fixedly installed on the support plate 7. This allows the rotating shaft 42 on the rotating shaft bracket 12 to be pressed between the support plate 7 and the base 1, making the overall structure more compact and eliminating the need for additional fastening members. Specifically, a bushing 8 may be provided on the rotating shaft 42, and the bushing 8 is provided between the support plate 7 and the base 1. The bushing 8 can increase resistance and reduce wear and noise between the rotating shaft 42 and the connecting groove.

[0028] 4-5, 8, and 13-14, in some embodiments, a mounting bracket 13 is fixedly installed on the support plate 7, and an assembly hole is provided in the mounting bracket 13, and the second connecting portion 62 of the damping member 6 may be provided in the assembly hole. Preferably, the assembly hole is a polygonal hole and the second connecting portion 62 has a corresponding polygonal structure. In this way, the second connecting portion 62 can be inserted into the assembly hole and is not rotated within the assembly hole, thereby realizing installation in a positionally restricted state.

[0029] As shown in Figures 5 to 7 and 10, in some embodiments, an adapter base 41 is provided on the support member 4, an adapter groove 15 is provided on the base 1, and the adapter base 41 is rotatably installed in the adapter groove 15, thereby realizing rotary folding. Specifically, the rotation shaft 42 and the limiting assembly are respectively installed on one side of the adapter base 41, and the damping member 6 is installed on the other side of the adapter base 41, thereby playing a role in ensuring balance during installation.

[0030] As shown in FIGS. 5 and 16 , in some embodiments, the base 1 is further provided with a locking mechanism that can be connected to or disconnected from the support member 4. When the locking mechanism is connected to the support member 4, it locks the support member 4, restricting its rotation on the base 1. When the locking mechanism is disconnected from the support member 4, the support member 4 can rotate on the base 1. Specifically, the locking mechanism may include a push-pull member 5 and an elastic member 16, and the elastic member 16 may be a spring. The push-pull member 5 is slidably mounted on the support plate 7 via the pressure plate 14 and is capable of reciprocating on the support plate 7. One end of the elastic member 16 is connected to the pressure plate 14, and the other end of the elastic member 16 is connected to the support plate 7. In its natural state, the elastic member 16 can maintain the pressure plate 14 in its initial state. At this time, the engagement hook 51 on the push-pull member 5 and the engagement block 44 on the support member 4 engage to lock the support member 4, preventing it from rotating on the base 1. When the engagement hook 51 on the push-pull member 5 is pulled and separated from the engagement block 44 on the support member 4, the support member 4 is unlocked and becomes rotatable. Once the support member 4 is unlocked and rotated, the push-pull member 5 can return to its original state by the restoring force of the elastic member 16.

[0031] As shown in Figures 1 to 5, the present application further provides a folding fan including the above-mentioned rotating assembly, a support pole 2, and a head 3. Specifically, the support pole 2 is attached to a support member 4, and the head 3 is attached to the support pole 2. Preferably, the support pole 2 may be a telescopic support pole, and the support pole 2 and the support member 4 are inserted together, and the support pole 2 and the head 3 are rotatably connected, which allows the entire fan to be folded, facilitating packaging and storage.

A person skilled in the art may make any modifications and changes to the embodiments and details without departing from the spirit and scope disclosed in the present application, but the scope of protection of the invention of the present application shall still be in accordance with the scope defined in the accompanying utility model registration claims.
