Description

Technical Field

[0002] Due to its practicality, the rotating structure is widely used in daily life. For example, the rotating structure can be applied to electronic device accessories such as mobile phone holders. An existing rotating structure is formed by winding a sheet-like structure. The sheet-like structure is bent and wound from one end to the other end to form a shaft hole, and there is a certain distance between the end of the winding part and the sheet-like structure, that is, the shaft hole is a circumferentially non-closed structure. The opening formed by the winding part can provide a deformation space for the deformation of the winding part during rotation, so as to produce a better rotation effect. After rotation, the winding part can return to its original position under the action of its own elastic force. However, the non-closed winding part will generate stress fatigue after multiple deformations and cannot be restored, resulting in a short service life and affecting the use of the rotating structure.

[0024] Before describing the embodiments in detail, it should be understood that the present application is not limited to the detailed structures or element arrangements described in the following text or the drawings of the present application. The present application can be implemented in other ways. Moreover, it should be understood that the terms and phrases used herein are only for descriptive purposes and should not be construed restrictively. The terms "including", "comprising", "having" and other similar phrases used herein are intended to include the matters listed thereafter, their equivalents and other additional matters. In particular, when describing "a certain element", the present application does not limit the number of such elements to one, and multiple elements can also be included.

[0025] Please refer to Figures 1 to 6As shown, the present application provides a rotating structure 10, which includes a rotating base 12. The rotating base 12 is, for example, a rectangular plate-like structure. The rotating base 12 has a first end 14 and a second end 16 that are opposite in the length direction. The first end 14 and the second end 16 are respectively wound towards the same side of the rotating base 12 and face each other, so as to respectively form a first wound circular structure 18 and a second wound circular structure 20. The first wound circular structure 18 and the second wound circular structure 20 are, for example, hole structures that penetrate through both ends, and the first end 14 and the second end 16 are fixedly connected. The rotating structure 10 of the present application can be applied to products with a double-rotating shaft structure. Through the cooperation of the two shafts, a larger rotation angle can be achieved. Moreover, the fixed connection of the two ends of the rotating base 12 makes the open ends of the two wound parts connected and fixed together to form a closed space. The connection of the two open ends can reduce the stress on the wound parts, thereby improving the structural stability of the wound parts and extending the service life of the rotating structure.

[0026] Preferably, the first wound circular structure 18 and the second wound circular structure 20 are arranged in parallel, that is, the axial direction of the first wound circular structure 18 is parallel to the axial direction of the second wound circular structure 20. The first wound circular structure 18 and the second wound circular structure 20, for example, both extend along the width direction of the rotating base 12. The first wound circular structure 18 and the second wound circular structure 20 are both used for inserting a rotating shaft.

[0027] More specifically, the rotating base 12 includes a base portion 22 and a first winding portion 24 and a second winding portion 26 connected to the left and right opposite ends of the base portion 22. The first winding portion 24, the second winding portion 26, and the base portion 22 are, for example, integrally formed structures. Among them, the first winding portion 24 is wound to form the first wound circular structure 18, and the second winding portion 26 is wound to form the second wound circular structure 20. Further, the rotating base 12 further includes a first extension portion 28 and a second extension portion 30. Among them, the first extension portion 28 extends from the end of the first winding portion 24 away from the base portion 22 towards the second winding portion 26, and the first end 14 is formed at the end of the first extension portion 28 away from the first winding portion 24. The second extension portion 30 extends from the end of the second winding portion 26 away from the base portion 22 towards the first winding portion 24, and the second end 16 is formed at the end of the second extension portion 30 away from the second winding portion 26.

[0028] In this embodiment, the first extension portion 28 and the second extension portion 30 can move between a first state and a second state. Among them, the first state is, for example, the normal state of the rotating structure 10 (that is, the rotating structure 10 does not undergo rotational deformation), and the second state is, for example, the state of the rotating structure 10 when rotational deformation occurs. In one implementation, in the first state, the first extension portion 28 and the second extension portion 30 are attached to the base portion 22. In the second state, the first extension portion 28 and the second extension portion 30 are separated from the base portion 22, so that the shaft hole formed by the first coiled circular structure 18 or the second coiled circular structure 20 increases, reducing the wear between the rotating shaft and the coiled circular structure. In another implementation, in the first state, there is a first gap between the first extension portion 28 and the second extension portion 30 and the base portion 22. In the second state, there is a second gap between the first extension portion 28 and the second extension portion 30 and the base portion 22, and the second gap is larger than the first gap, so that the shaft hole formed by the first coiled circular structure 18 or the second coiled circular structure 20 increases, reducing the wear between the rotating shaft and the coiled circular structure.

[0029] Preferably, in the normal state, the first extension portion 28 and the second extension portion 30 can be set to be parallel to the base portion 22, and the first extension portion 28 and the second extension portion 30 are both arranged in contact with the base portion 22. In addition, when the first extension portion 28 and the second extension portion 30 are arranged at intervals from the base portion 22, the spaced space formed between the first extension portion 28 and the second extension portion 30 and the base portion 22 communicates between the first coiled circular structure 18 and the second coiled circular structure 20.

[0030] In the illustrated embodiment, the first winding portion 24, the second winding portion 26, the first extension portion 28, and the second extension portion 30 jointly enclose an elastic expansion space 32. The elastic expansion space 32 is, for example, a groove structure, and the elastic expansion space 32 is used to avoid the elastic deformation of the first winding portion 24 and / or the second winding portion 26. With such a setting, during the rotation of the rotating structure 10, the first extension portion 28 and the second extension portion 30 can move left and right or up and down relative to the base portion 22 according to the actual force situation, enabling the first winding portion 24 and the second winding portion 26 to undergo a certain amount of elastic deformation toward the elastic expansion space 32 during the rotation process. The elastic expansion space 32 correspondingly shrinks, providing a rotational damping force and elastic force for the rotating shaft, and at the same time enabling the first coiled circular structure 18 and the second coiled circular structure 20 to expand to a certain extent, reducing wear and extending the service life. When the first winding portion 24 and the second winding portion 26 are elastically restored, the elastic expansion space 32 is restored accordingly.

[0031] In this embodiment, the first end 14 is, for example, the end face of the first extension portion 28 away from one end of the first winding portion 24, and the second end 16 is, for example, the end face of the second extension portion 30 away from one end of the second winding portion 26. The first end 14 and the second end 16 can be fixedly connected by processes such as welding and press riveting, so as to form a closed space inside the rotating base 12. Preferably, the first end 14 is provided with a first concave-convex connecting portion 34, and the second end 16 is provided with a second concave-convex connecting portion 36. The first concave-convex connecting portion 34 and the second concave-convex connecting portion 36 are, for example, concave-convex serrated structures, and the first concave-convex connecting portion 34 and the second concave-convex connecting portion 36 are engaged with each other in a concave-convex manner, which can strengthen the connection firmness between the first extension portion 28 and the second extension portion 30.

[0032] In the illustrated embodiment, corresponding limiting notches 38 are respectively provided at both axial ends of the second winding portion 26. The limiting notches 38 can be used for limiting cooperation with an external limiting structure to realize the rotational limit of the rotating structure. By restricting the size of the limiting notches 38, the control of the rotation angle between the rotating shaft and the coiled structure can be realized. For example, the limiting notch 38 has two limiting end faces opposite to each other in the circumferential direction. By setting the included angle range between the two limiting end faces of the limiting notch 38 to be between 70° and 110°, the rotation angle between the rotating shaft and the coiled structure can be restricted within a certain range. The limiting notch 38 can be provided on the arc wall of the second winding portion 26 away from the first winding portion 24 and the base portion 22. Specifically, the limiting notch 38 has two limiting end faces 39 opposite to each other in the circumferential direction. When the two limiting end faces 39 are perpendicular to each other, that is, the included angle between them is 90 degrees, and the plane where the limiting end face 39 is located passes through the axis of the second coiled structure 20, the rotation angle range of the rotating shaft relative to the coiled structure is then between 0° and 90°. Preferably, the width of the limiting end face 39 in the axial direction of the second coiled structure 20 is greater than or equal to 1 mm. Such a setting can ensure the stability when the limiting notch 38 is in limiting abutment with the corresponding external limiting structure. Because, if the width of the limiting end face 39 is less than 1 mm, the limiting abutment is not firm and the limiting effect cannot be formed. In some other embodiments, only one limiting notch 38 can also be provided, and the limiting notch 38 is provided at the axial end of the second winding portion 26.

[0033] In the example as Figures 1 - 2 shown, both the first coiled structure 18 and the second coiled structure 20 are circular holes.

[0034] In the example as Figures 3 - 4In the illustrated embodiment, a first self-locking flat position plane 40 is formed on the hole wall of the first coiled circular structure 18. The first self-locking flat position plane 40 can be provided on the top surface, bottom surface or side surface of the first coiled circular structure 18. A second self-locking flat position plane 42 is formed on the hole wall of the second coiled circular structure 20. The second self-locking flat position plane 42 can be provided on the top surface, bottom surface or side surface of the second coiled circular structure 20. In this embodiment, one first self-locking flat position plane 40 is provided and is located on the top surface of the first coiled circular structure 18; one second self-locking flat position plane 42 is provided and is located on the side surface of the second coiled circular structure 20 on the side away from the first coiled circular structure 18. The first self-locking flat position plane 40 and the second self-locking flat position plane 42 both extend along the width direction of the rotating base 12, for example. Preferably, the length of the first self-locking flat position plane 40 is the same as the length of the first coiled circular structure 18, and the length of the second self-locking flat position plane 42 is the same as the length of the second coiled circular structure 20. By providing self-locking flat position planes in the shaft hole and corresponding flat position planes on the side wall of the rotating shaft at the same time, the damping force between the rotating shaft and the shaft hole during the rotation process can be increased, and the functions of stable rotation and stable rotation positioning can be achieved.

[0035] In the embodiment as Figures 5 - 6 shown, two first self-locking flat position planes 40 are provided. The two first self-locking flat position planes 40 are respectively provided on the top surface and the bottom surface of the first coiled circular structure 18, and the two first self-locking flat position planes 40 are arranged in parallel; two second self-locking flat position planes 42 are provided. The two second self-locking flat position planes 42 are respectively provided on the top surface and the bottom surface of the second coiled circular structure 20, and the two second self-locking flat position planes 42 are arranged in parallel, which can further increase the rotation stability and the rotation positioning ability.

[0036] In summary, the present application provides a rotating structure, including a rotating base. The rotating base has opposite first and second ends. The first and second ends are respectively wound toward the same side of the rotating base and face each other to respectively form a first coiled circular structure and a second coiled circular structure, and the first end and the second end are fixedly connected. The rotating structure of the present application can be applied to products with a double rotating shaft structure. Through the cooperation of the two shafts, a larger rotation angle can be achieved. Moreover, the fixed connection of the two ends of the rotating base makes the open ends of the two winding parts connected and fixed together to form a closed space. The connection of the two open ends can reduce the stress on the winding parts, thereby improving the structural stability of the winding parts and extending the service life of the rotating structure.

[0037] The concepts described herein can be implemented in other forms without departing from their spirit and characteristics. The specific embodiments disclosed should be considered illustrative rather than restrictive. Therefore, the scope of the present application is determined by the appended claims rather than by these previous descriptions.
