Description

Technical Field

[0001] This invention relates to the field of electronic product base technology, and in particular to a rotating base structure. Background Technology

[0002] A swivel stand is a type of stand design used in various products, such as LCD TVs, monitors, or other electronic devices. Existing swivel stands generally consist of a main base, a rotating bracket, and a torque mechanism. The main base is a platform or base plate used to support the TV and provide a stable foundation. The rotating bracket is usually located above the main base and connected to it via an axis. It allows the TV to rotate horizontally for adjustment according to desired viewing angles. The torque mechanism provides torque on the rotating axis, allowing users to easily rotate the TV; common torque mechanisms include gear and bearing structures.

[0003] However, the aforementioned rotating base structure has some drawbacks, one of which is its inapplicability to micro-electronic products, such as small speakers. This is because traditional rotating base structures are typically designed for larger devices, resulting in a bulky size that cannot meet the size requirements of micro-products. Furthermore, micro-electronic products usually require a more compact design to meet portability and space constraints. Therefore, it is necessary to develop a rotating base specifically for small electronic products and address the aforementioned issues. Summary of the Invention

[0004] Therefore, the present invention provides a rotating base structure to solve the above problems.

[0005] To achieve the objectives of this invention, the following technical solution is adopted:

[0006] A rotating base structure, comprising:

[0007] The main outer shell serves as the overall load-bearing structure;

[0008] A rotating unit is rotatably connected to the main body shell. The rotating unit includes a first rotating body and a second rotating body that fit together with each other. The first rotating body and the second rotating body are respectively assembled into the main body shell from the upper and lower ends of the main body shell.

[0009] A cover, which is connected to the second rotating body via a connector and is located above the first rotating body; and

[0010] An elastic element is disposed between the cover and the first rotating body to provide rotational torque to the rotating unit when the main body shell rotates.

[0011] Furthermore, the main body shell includes a housing; a housing through hole is passed through the middle of the housing; an assembly flange extends from the housing through hole along its center direction; a first placement groove and a second placement groove are formed from top to bottom in the housing through hole with the assembly flange as the dividing surface; the first placement groove is for the first rotating body to be aligned and assembled; the second placement groove is for the second rotating body to be aligned and assembled.

[0012] Furthermore, the first rotating body includes a first disc; a first mounting boss extends upward from the upper end of the first disc, and a second mounting boss extends downward from the lower end; a fitting through hole extends from the first mounting boss to the second mounting boss; the fitting through hole is for the second rotating body to fit together.

[0013] Furthermore, the shape of the fitting through hole is a rounded rectangle.

[0014] Furthermore, the second rotating body includes a second disc; a third mounting boss extends upward from the upper end surface of the second disc; the third mounting boss is provided with a downwardly extending clearance groove.

[0015] Furthermore, the lower end surface of the second disc is provided with anti-slip contacts.

[0016] Furthermore, the cover has a downwardly extending edge wall and a downwardly recessed central groove in the middle.

[0017] Furthermore, the elastic element is selected as a wave-shaped spring sheet.

[0018] Furthermore, the connector is a screw; the cover has an assembly hole; the assembly hole allows the body of the connector to pass through; the second rotating body has a threaded hole corresponding to the position of the assembly hole; the connector passes through the assembly hole and connects with the threaded hole.

[0019] Furthermore, it also includes a gasket; the gasket is disposed between the rotating unit and the main body shell.

[0020] The beneficial effects of this invention are as follows:

[0021] Compact structure, suitable for miniaturized electronic products: By installing the rotating unit at the upper and lower ends of the main body shell and the cover above the first rotating body, this rotating base structure has the advantages of being compact and suitable for miniaturized electronic products compared to the large structure of the previous base with rotating shaft.

[0022] Furthermore, the rotating unit consists of a first rotating body and a second rotating body that fit together, achieving a stable connection by being assembled at the upper and lower ends of the main body shell. This fitting structure provides excellent rotational performance and reliability. To ensure synchronous rotation of the first and second rotating bodies, the fitting through-hole is rounded rectangular in shape. After fitting, the first and second rotating bodies are relatively fixedly connected, achieving synchronous rotation. This eliminates the need for additional accessories such as screws, rivets, and snap-fit ​​structures for assembly and locking, improving assembly efficiency, reducing overall size, and making it more suitable for use in small electronic products.

[0023] High assembly efficiency: This rotating base structure consists of a main shell, rotating units mounted on the upper and lower ends of the main shell, and a cover connected to the rotating units. During assembly, the rotating units are first inserted into the main shell from the upper and lower sides, then elastic elements are placed on the rotating units and the cover is locked to complete the assembly. Compared with the existing complex base structure, this greatly improves the assembly efficiency. Attached Figure Description

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0041] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0043] like Figures 1-10 As shown, a rotating base structure includes: a main body shell 10, a rotating unit 20, a cover 30, and an elastic element 40;

[0044] The main body shell 10 is used for overall support; in this embodiment, the main body shell 10 includes a shell 11; a shell through hole 12 is passed through the middle of the shell 11; a mounting flange 13 extends from the center of the shell through hole 12; a first placement groove 14 and a second placement groove 15 are formed from top to bottom in the shell through hole 12 with the mounting flange 13 as the dividing surface; the first placement groove 14 is for the first rotating body 21 to be aligned and assembled; the second placement groove 15 is for the second rotating body 22 to be aligned and assembled;

[0045] The main body shell 10 is provided with a product assembly groove. Specifically, the product assembly groove includes an assembly step 16 provided at the top edge of the shell 11 for product docking and assembly.

[0046] The rotating unit 20 is rotatably connected to the main body shell 10. The rotating unit 20 includes a first rotating body 21 and a second rotating body 22 that fit together. The first rotating body 21 and the second rotating body 22 are respectively assembled into the main body shell 10 from the upper and lower ends of the main body shell 10.

[0047] In this embodiment, the first rotating body 21 includes a first disc 21a; a first mounting boss 21b extends upward from the upper end of the first disc 21a, and a second mounting boss 21c extends downward from the lower end; a fitting through hole 21d passes through from the first mounting boss 21b to the second mounting boss 21c; the fitting through hole 21d allows the second rotating body 22 to be fitted and connected; during assembly, the first disc 21a is correspondingly disposed in the first placement groove 14 of the main body shell 10, and the second mounting boss 21c is correspondingly located on the inner periphery of the mounting flange 13;

[0048] Furthermore, in order to enable the first rotating body 21 and the second rotating body 22 to rotate synchronously, the shape of the fitting through hole 21d is a rounded rectangle. After the fitting connection, the first rotating body 21 and the second rotating body 22 are relatively fixedly connected to achieve synchronous rotation. There is no need to use additional accessories such as screws, rivets and buckle structures for assembly and locking, which improves assembly efficiency, reduces the overall size, and is more suitable for use in small electronic products.

[0049] The second rotating body 22 includes a second disc 22a; a third mounting boss 22b extends upward from the upper end surface of the second disc 22a; the third mounting boss 22b is provided with a downward extending clearance groove 22c; the shape of the third mounting boss 22b matches the fitting through hole 21d; during assembly, the third mounting boss 22b is inserted upward into the fitting through hole 21d, at which time the third disc is located in the second placement groove 15 of the main body shell 10;

[0050] To increase anti-slip performance, the lower end surface of the second disc 22a is provided with anti-slip contact points 22d to increase friction.

[0051] The cover 30 is connected to the second rotating body 22 via a connector 34 and is located above the first rotating body 21. In this embodiment, the edge of the cover 30 extends downward with an edge extension wall 31, and a downward-sloping central groove 32 is provided in the middle. After assembly, an elastic assembly space for assembling the elastic element 40 is formed between the edge extension wall 31, the cover 30, the first assembly boss 21b, and the first disc 21a. The elastic assembly space 60 formed by the above structure occupies little space and realizes the possibility of assembling the damping element in a small electronic product.

[0052] The elastic element 40 is disposed between the cover 30 and the first rotating body 21 to provide rotational torque to the rotating unit 20 when the main body shell 10 rotates. In this embodiment, the elastic element 40 is a wave spring. Since the axial distance of the elastic assembly space is short, the wave spring has a smaller size and volume than the traditional spring, which can achieve rotational damping in a limited axial space, making it thinner and lighter, and reducing the weight and space requirements of the overall assembly. Moreover, unlike the traditional spring, the damping characteristics of the wave spring can be adjusted and customized by changing its geometry, material properties and fixing method, and can provide non-linear damping characteristics. This means that during rotation, the damping capacity of the wave spring can be adjusted according to the force conditions to achieve different damping behaviors.

[0053] Regarding the selection of the connector 34, in this embodiment, the connector 34 is a screw; the cover 30 is provided with an assembly hole 33; the assembly hole 33 allows the body of the connector 34 to pass through, that is, the inner diameter of the assembly hole 33 is greater than the outer diameter of the screw thread; the second rotating body 22 is provided with a threaded hole 22e corresponding to the position of the assembly hole 33; the connector 34 passes through the assembly hole 33 and connects with the threaded hole 22e; specifically, the connector 34 is a screw, and the outer diameter of the nut at the upper end of the screw is larger than the assembly hole 33, which can axially lock the cover 30; after assembly, the cover 30 has corresponding axial movement space depending on the length of the connector 34;

[0054] Furthermore, to improve the smoothness of rotation, a shim 50 is also included; the shim 50 is disposed between the rotating unit 20 and the main body shell 10; since the torque of this rotating base is generated by the rebound of the elastic element 40, the rebound force of the elastic element 40 is converted into the clamping friction force of the first rotating body 21 and the second rotating body 22 on the main body shell 10, and the clamping friction force is generated between the first rotating body 21 and the first placement groove 14, and between the second rotating body 22 and the second placement groove 15. In this embodiment, the shim 50 is disposed between the second placement groove 15 and the second disc 22a, which can reduce the friction force between the second rotating body 22 and the main body shell 10, so that the area where the clamping friction force is generated is concentrated between the first rotating body 21 and the first placement groove 14, reducing adjustment impurities, increasing the adjustment range, and making it easier to control the overall torque of this rotating base, thereby providing a smoother feel.

[0055] Working principle:

[0056] After the rotating base structure is assembled, the main shell 10 is then assembled with the product body to form the finished product. At this time, the main shell 10 is the rotating end, and the rotating unit 20, the cover 30, and the elastic unit are the relatively stationary ends.

[0057] The first rotating body 21 and the second rotating body 22 are installed at both ends of the main body shell 10. The cover 30 is connected to the second rotating body 22 through the connector 34, and the cover 30 is located above the first rotating body 21. The elastic element 40 is placed between the cover 30 and the first rotating body 21. The rebound force of the elastic element 40 pushes the cover 30 up. The cover 30 drives the second rotating body 22 to move upward through the connector 34. That is, the first rotating body 21 and the second rotating body 22 clamp the main body shell 10 together. The rebound force of the elastic element 40 is converted into friction between the rotating unit 20 and the main body shell 10, thereby providing a damping feel when rotating.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
