Abstract
Description
Technical Field
[0001] This application relates to a shaft structure, and more particularly to a damped shaft structure capable of supplying power lines. Background Technology
[0002] Hinge structures are widely used in various devices, equipment, or machines. They are primarily used to connect two different components, allowing them to rotate relative to each other. Damping effects are achieved through viscous fluids, spring torque, friction, or fluid pressure, ensuring smooth rotation and reducing vibration and noise. Wired hinge structures, in addition to providing the aforementioned functions, also have a through-hole at the center for power or signal cables to pass through, preventing tangling or knotting during rotation.
[0003] However, most existing wire-threaded shaft structures are assembled from multiple metal parts by riveting or locking, resulting in large size, numerous components, complex structure, high production costs, heavy weight, and cumbersome and time-consuming assembly processes. Furthermore, due to the large number of components and complex structure of existing wire-threaded shaft structures, the diameter of the through holes for wire threading is limited, making it impossible to accommodate thicker or larger wires. Therefore, designing a wire-threaded shaft structure that reduces the number and cost of parts while increasing the diameter of the through holes is a pressing need to address these shortcomings.
[0004] In view of this, the applicant has devoted himself to researching and applying theoretical principles to address the shortcomings of the prior art, and has made every effort to solve the aforementioned problems, which has become the target of the applicant's improvement.

[0054] The detailed description and technical content of this application will be explained in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application.
[0055] This application provides a damped shaft structure 100, which can accommodate at least one wire A (visible in...). Figure 9 (Pass through. Please refer to...) Figures 1 to 3 The image shows a first embodiment of the damped rotating shaft structure 100 of this application, which includes a first turntable seat 110, a second turntable seat 120 and an elastic damping ring 130.
[0056] In this embodiment, the first turntable base 110 is integrally molded from plastic and is generally flat, thereby effectively reducing cost and weight, but this application is not limited thereto. The first turntable base 110 has a first through hole 111. The first through hole 111 penetrates the first turntable base 110. In this embodiment, the first through hole 111 is located at the center of the first turntable base 110, but this application is not limited thereto.
[0057] In this embodiment, the second turntable seat 120 corresponds to the first turntable seat 110 and is also integrally molded from plastic, generally in the form of a flat plate, thereby effectively reducing cost and weight, but this application is not limited thereto. The second turntable seat 120 is rotatably connected to the first turntable seat 110. Specifically, in this embodiment, the second turntable seat 120 is rotatably disposed above the first turntable seat 110, but in other embodiments, the second turntable seat 120 may also be rotatably disposed below the first turntable seat 110. The second turntable seat 120 has a second through hole 121 communicating with the first through hole 111. The second through hole 121 penetrates the second turntable seat 120. In this embodiment, the second through hole 121 is located at the center of the second turntable seat 120 and is positioned corresponding to the first through hole 111, thereby connecting the second through hole 121 to the first through hole 111, but the position of the second through hole 121 in this application is not limited thereto.
[0058] The elastic damping ring 130 is annular. In this embodiment, the elastic damping ring 130 is a rubber ring, but this application is not limited to this; for example, the elastic damping ring 130 can also be made of silicone or other elastic materials. The elastic damping ring 130 is disposed on the first turntable seat 110 or the second turntable seat 120, and the elastic damping ring 130 elastically abuts between the first turntable seat 110 and the second turntable seat 120. The elastic damping ring 130 surrounds the outside of the first through hole 111 and the second through hole 121, so that the wire A can pass through the first through hole 111 of the first turntable seat 110, the second through hole 121 of the second turntable seat 120, and the elastic damping ring 130.
[0059] Therefore, when the user rotates the second turntable seat 120 relative to the first turntable seat 110 in a rotational direction, the elastic damping ring 130 can apply a damping torque to the second turntable seat 120 in the opposite direction of rotation, thereby allowing the user to make stepless damped adjustments to the second turntable seat 120. Furthermore, after the user stops rotating the second turntable seat 120, the elastic damping ring 130 can use its own elasticity to elastically abut against the first turntable seat 110 and the second turntable seat 120 to form a positioning, thereby preventing further rotation between them. In addition, by having the elastic damping ring 130 surround the first through hole 111 of the first turntable seat 110 and the second through hole 121 of the second turntable seat 120, the wire hole diameter of the damped rotating shaft structure 100 of this application can be effectively increased.
[0060] In this embodiment, the second turntable base 120 has a plurality of hooks 122 arranged around the second through hole 121, and each hook 122 extends downward from the bottom surface of the second turntable base 120 and passes through the first through hole 111 to engage with the first turntable base 110. However, in other embodiments, each hook 122 may also be arranged on the first turntable base 110 and surround the first through hole 111. Specifically, when the second turntable base 120 is assembled with the first turntable base 110 in this embodiment, each hook 122 of the second turntable base 120 is first aligned with the first through hole 111 of the first turntable base 110. Then, the second turntable base 120 is pressed against the first turntable base 110 so that each hook 122 is engaged in the first through hole 111 of the first turntable base 110 until the end of each hook 122 passes through the first through hole 111 of the first turntable base 110 and engages with the side of the first turntable base 110 away from the second turntable base 120 to form a lock.
[0061] To further explain, each hook 122 includes an extension arm 1221 and a barb portion 1222. In each hook 122, the extension arm 1221 extends from the bottom surface of the second turntable seat 120 and connects the second turntable seat 120 and the barb portion 1222. Therefore, when the second turntable seat 120 is pressed against the first turntable seat 110 so that each hook 122 engages with the first through hole 111 of the first turntable seat 110, each extension arm 1221 of each hook 122 can elastically deform and collapse inward. After each barb portion 1222 of each hook 122 passes through the first through hole 111 of the first turntable seat 110, each hook 122 can then reset its extension arm 1221 through its own elasticity, while simultaneously locking the barb portion 1222 onto the side of the first turntable seat 110 away from the second turntable seat 120 to form a lock. Furthermore, each hook 122 has a barb portion 1222 with a guide slope 1222A. Each guide slope 1222A is formed on the outside of the barb portion 1222, thereby having a guiding effect when each hook 122 is engaged in the first through hole 111, which facilitates the pressing and assembly of the first turntable seat 110 and the second turntable seat 120.
[0062] Furthermore, in this embodiment, the first turntable seat 110 has an annular groove 101, and the second turntable seat 120 has abutting structure 102 protruding from its surface. Specifically, the top surface of the first turntable seat 110 has an inner flange 103 and an outer flange 104. The inner flange 103 is annular and surrounds the first through hole 111, and the outer flange 104 is also annular and surrounds the inner flange 103, forming an annular groove 101 between the two. An elastic damping ring 130 is disposed in the annular groove 101 between the inner flange 103 and the outer flange 104, thereby being abutted between the abutting structure 102 of the first turntable seat 110 and the second turntable seat 120. More specifically, in this embodiment, the elastic damping ring 130 is detachably housed within the annular groove 101. That is, when the second turntable seat 120 is fastened to the first turntable seat 110 by the hooks 122, the elastic damping ring 130 elastically abuts against the bottom of the annular groove 101 and the abutment structure 102 of the second turntable seat 120. The abutment structure 102 can be an annular flange or a plurality of protrusions arranged in an annular shape, thereby tightly abutting against the elastic damping ring 130 to ensure that the elastic damping ring 130 can generate damping torque when the second turntable seat 120 rotates.
[0063] However, this application is not limited to the foregoing. Please refer to [link / reference]. Figure 4 The diagram shows a second embodiment of the damped rotating shaft structure 100 of this application. The main difference between this embodiment and the first embodiment is that the elastic damping ring 130 is tightly embedded in the annular groove 101 via an injection molding process. More specifically, the elastic damping ring 130 is injection molded together with the first turntable seat 110, thereby tightly encapsulating and fixing the elastic damping ring 130 within the annular groove 101 of the first turntable seat 110. This saves assembly steps and improves the tightness between the elastic damping ring 130 and the first turntable seat 110.
[0064] Please refer to the following: Figure 5 The diagram shows a third embodiment of the damped rotating shaft structure 100 of this application. The main difference between this embodiment and the first embodiment lies in the placement of the elastic damping ring 130, the annular groove 101, and the abutment structure 102. Specifically, in this embodiment, the annular groove 101 is formed in the second turntable seat 120, and the abutment structure 102 is formed in the first turntable seat 110. Therefore, the elastic damping ring 130 is accommodated within the annular groove 101 of the second turntable seat 120, and when the second turntable seat 120 is fastened to the first turntable seat 110 by the hooks 122, the elastic damping ring 130 is elastically abutted between the second turntable seat 120 and the abutment structure 102 of the first turntable seat 110. This achieves the same effect as the first embodiment.
[0065] Please continue reading. Figure 6The diagram shows a fourth embodiment of the damped rotating shaft structure 100 of this application. The main difference between this embodiment and the third embodiment is that the elastic damping ring 130 is tightly embedded in the annular groove 101 via an injection molding process. More specifically, the elastic damping ring 130 is injection molded together with the second turntable seat 120, thereby tightly encapsulating and fixing the elastic damping ring 130 within the annular groove 101 of the second turntable seat 120. This saves assembly steps and improves the tightness between the elastic damping ring 130 and the second turntable seat 120.
[0066] Please continue reading. Figures 7 to 9 As shown, this application also provides a handheld camera device, which mainly includes the damped rotating shaft structure 100, camera 200, pivot seat 300 and grip 400 as described above.
[0067] In this embodiment, since the second turntable base 120 is rotatably connected above the first turntable base 110, the camera 200 is disposed on the second turntable base 120, and the pivot base 300 is disposed on the first turntable base 110. However, this application is not limited thereto. For example, when the second turntable base 120 is rotatably connected below the first turntable base 110, the camera 200 is disposed on the first turntable base 110, and the pivot base 300 is disposed on the second turntable base 120. The camera 200 can be a mobile phone, camera, action camera, action video camera, etc. In this embodiment, the camera 200 shown in the figure is an action video camera, but this application does not impose further limitations on this. The grip 400 is pivotally connected to the pivot base 300 and is provided for the user to hold. In this way, the camera 200 can rotate left and right relative to the first turntable 110, the pivot 300 and the handle 400 via the second turntable base 120, while the handle 400 can rotate back and forth relative to the camera 200, the second turntable base 120, the first turntable base 110 and the pivot 300.
[0068] Furthermore, the handheld camera device in this embodiment also includes at least one wire A. Wire A passes through the first through hole 111, the second through hole 121, the elastic damping ring 130, and the pivot seat 300, so that both ends of wire A are located in the camera 200 and the grip 400, respectively. Specifically, one end of wire A can be electrically connected to the camera 200, and the other end of wire A can be electrically connected to a circuit board (not shown) in the grip 400, so that the camera 200 can be electrically connected to the circuit board, thereby operating or charging the camera 200 through a button (not labeled) or a charging port (not labeled) on the grip 400. In addition, when the camera 200 rotates left and right relative to the first turntable 110, the pivot 300 and the handle 400 via the second turntable base 120, or rotates back and forth relative to the camera 200, the second turntable base 120, the first turntable base 110 and the pivot 300, the wire A will not become tangled or knotted.
[0069] The damping shaft structure 100 of this application is rotatably connected to the first turntable seat 110 via the second turntable seat 120, and the elastic damping ring 130 elastically abuts between the first turntable seat 110 and the second turntable seat 120. Therefore, the number of parts and the cost of parts in the damping shaft structure 100 of this application can be reduced. Furthermore, by having the elastic damping ring 130 surround the first through hole 111 of the first turntable seat 110 and the second through hole 121 of the second turntable seat 120, the wire hole diameter of the damping shaft structure 100 of this application can be effectively increased.
[0070] The handheld camera device of this application has a camera 200 mounted on a second turntable base 120, a pivot base 300 mounted on a first turntable base 110, and a handle 400 pivotally connected to the pivot base 300, so that the camera 200 can rotate left and right relative to the first turntable base 110, the pivot base 300 and the handle 400 via the second turntable base 120, while the handle 400 can rotate back and forth relative to the camera 200, the second turntable base 120, the first turntable base 110 and the pivot base 300.
[0071] In summary, the foregoing descriptions in this application are intended to enable those skilled in the art to clearly understand the technical content of this application and implement it accordingly, and are not intended to limit the scope of patent protection of this application. In addition, this application may naturally have other embodiments not listed. Without departing from the spirit and essence of this application, those skilled in the art should be able to devise various corresponding changes and modifications based on this application, but all such corresponding changes and modifications should fall within the scope of protection of the patent claimed in this application.
