The rotating structure of the present invention and the electronic device using the same will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 , an electronic device 20 according to a preferred embodiment of the present invention includes a body 201 , a cover 203 , and a rotating structure 21 connecting the body 201 and the cover 203 .

Referring to FIG. 2, the rotating structure 21 includes a base 210, a rotating member 230 disposed on the base 210, and a protective sleeve 250 for protecting the base 210 and the rotating member 230.

The base 210 has a disc shape and includes a resisting surface 211 and a connecting surface 213 opposite to the resisting surface 211. A cylindrical protrusion 215 and an annular protrusion 217 are formed on the resisting surface 211. The cylindrical protrusion 215 is located at the middle of the abutting surface 211, and the annular protrusion 217 is located at the edge of the abutting surface 211, and the height of the cylindrical protrusion 215 is greater than the height of the annular protrusion 217.

The cylindrical projection 215 is formed with a locking portion 2151 away from one end of the base 210. The locking portion 2151 can be a tapered protrusion, a spherical protrusion, or the like. In this embodiment, the locking portion 2151 is a tapered protrusion. In addition, the cylindrical protrusion 215 is provided with an opening 2153 extending through the locking portion, so that the cylindrical protrusion 215 can be elastically deformed by an external force.

The rotating member 230 is in the form of a flat plate and includes a bottom surface 231 and a supporting surface 233 opposite to the bottom surface 231. Moreover, the rotating member 230 defines a circular through hole 235 extending through the bottom surface 231 and the supporting surface 233.

The protective sleeve 250 has a cylindrical shape, and a circular through hole 251 is formed in a middle portion thereof. Moreover, the outer diameter of the protective sleeve 250 is slightly larger than the inner diameter of the circular through hole 235 of the rotating member 230, so as to ensure The sleeve 250 can be fixed in the circular through hole 235 of the rotating member 230 by interference fit. In addition, a flange 253 is formed on the outer side of one end of the protective sleeve 250. After the protective sleeve 250 is fixed to the circular through hole 235 of the rotating member 230, the flange 253 can resist the circular through hole 235 of the rotating member 230. The edge prevents the flange 253 from being terminated by a circular through hole 235. The material of the protective sleeve 250 is plastic. In the embodiment, the material of the protective sleeve 250 is nylon plastic.

Referring to FIGS. 3 and 4 again, during assembly, the protective sleeve 250 is disposed in the circular through hole 235 of the rotating member 230, and the flange 253 abuts against the supporting surface 233 of the rotating member 230. Then, the locking portion 2151 of the cylindrical projection 215 of the base 210 abuts against the edge of the circular through hole 235 from the side of the bottom surface 231 of the rotating member 230. Pressing the base 210, the locking portion 2151 of the cylindrical projection 215 is deformed by the opening 2153 and embedded in the circular through hole 251 of the protective sleeve 250. The base 210 is continuously pressed, and the locking portion 2151 slides along the inner wall of the circular through hole 251 in the circular through hole 251 of the protective sleeve 250, and finally passes through the circular through hole 251. Then, the locking portion 2151 resumes elastic deformation, and the locking portion 2151 abuts against the outside of the flange 253 of the protective sleeve 250, thereby preventing the rotating member 230 from coming off the base 210.

After the assembly of the rotating structure 21 is completed, the connecting surface 213 of the base 210 is connected to the body 201, and the cover 203 is disposed on the supporting surface 233 of the rotating member 230, that is, the electronic device 20 shown in FIG. 1 is obtained. The rotating member 230 is acted upon by the cylindrical protrusion 215 of the base 210. The rotating member 230 can rotate relative to the base 210 with the cylindrical protrusion 215 as a center, thereby realizing the rotation of the cover 203 relative to the body 201.

During the assembly process, the locking portion 2151 of the cylindrical protrusion 215 can pass through the circular through hole 251 of the protection sleeve 250 by being deformed by the opening 2153, which has the advantage of being easy to assemble. Moreover, the locking portion 2151 passes through the circular through hole 251 of the protection sleeve 250 to recover deformation and The outer side of the flange 253 of the protective sleeve 250 is resisted, so that the rotating member 230 is prevented from falling off from the base 210, and the rotating member 230 is not detached from the base 210 during use, and has good structural stability.

The annular protrusion 217 of the base 210 is in contact with the bottom surface 231 of the rotating member 230, and the rotating process forms a sliding friction, so that the rotating member 230 and the base 210 can maintain a stable state at any relative position.

Since the material of the protective sleeve 250 is a nylon plastic, the protective sleeve 250 has a relatively smooth inner wall, and the cylindrical protrusion 215 and the protective sleeve 250 have a small frictional force during assembly, and the cylindrical protrusion 215 has a relatively small frictional force. Good protection. Moreover, the locking portion 2151 is a tapered protrusion, and the top end thereof has a good guiding effect when the locking portion 2151 is embedded in the circular through hole 251 of the protection sleeve 250. Moreover, during the sliding of the locking portion 2151 in the circular through hole 251 of the protective sleeve 250 along the inner wall of the circular through hole 251, the contact area between the tapered protrusion and the inner wall of the circular through hole 251 is small. It can reduce the friction between each other and facilitate assembly.

Since the material of the protective sleeve 250 is nylon plastic, the friction coefficient of the protective sleeve 250 and the cylindrical protrusion 215 is small, and the wear sleeve 250 has less wear on the cylindrical protrusion 215 during use, so the rotating structure 21 has a long service life. It will be appreciated that the protective sleeve 250 may also be omitted in view of cost factors.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
