Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, an embodiment of the invention discloses an electronic device, which includes a housing 100, a driving mechanism 200, and a driven device 300.

The housing 100 is a base member of the electronic apparatus, and the housing 100 can provide a mounting base for other components of the electronic apparatus. The driving mechanism 200 and the driven device 300 are both provided to the housing 100. In the embodiment of the present invention, the casing 100 has an inner cavity and a through hole 110, the through hole 110 is communicated with the inner cavity and further allows the driven device 300 to pass through, and finally, the position of the driven device 300 inside and outside the casing 100 is switched.

In an alternative, the housing 100 may include a middle frame, and the through hole 110 may be opened on the middle frame. Of course, the through hole 110 may be opened at other positions of the casing 100, and the embodiment of the invention does not limit the specific position of the through hole 110.

The driving mechanism 200 is rotatably provided on the housing 100, and the driving mechanism 200 includes a base 210, an electromagnetic coil, and a moving body 230.

The base 210 is rotatably coupled to the housing 100 so as to rotate relative to the housing 100, and rotation of the base 210 enables rotation of the entire drive mechanism 200 relative to the housing 100. The base 210 has a slide 211, and the moving body 230 is movably disposed in the slide 211.

The electromagnetic coil is disposed on the base 210. The movable body 230 is movable in the slide channel 211 according to the magnetic variation of the electromagnetic coil, that is, the magnetic force generated by the electromagnetic coil drives the movable body 230 to move in the slide channel 211. The base 210 may rotate with the movement of the mover 230. In a specific working process, if the moving body 230 moves, the base 210 is driven to rotate, so as to drive the base 210 to rotate, and thus the rotation of the entire driving mechanism 200 is realized.

The driven device 300 is disposed on the base 210, and the driven device 300 is disposed on one side of the rotation axis of the base 210, that is, the driven device 300 and the rotation axis of the base 210 are disposed at an interval, and the base 210 can drive the driven device 300 to change its position in the process of rotation. Specifically, the base 210 may be provided with a mounting hole 212, and the driven device 300 may be fixed in the mounting hole 212, thereby implementing the mounting on the driving mechanism 200. Specifically, the driven device 300 may be fixed in the mounting hole 212 in a snap-fit or adhesive manner.

With the solenoid in the first state, the solenoid drives the moving body 230 to move, and the driving mechanism 200 rotates, so that the driven device 300 protrudes out of the housing 100 through the through hole 110. Specifically, the first state may be a state in which the electromagnetic coil is in a first energized state, and in the first energized state, the electromagnetic coil generates a first magnetic force on the movable body 230, thereby driving the movable body 230 to move in the first direction.

With the solenoid in the second state, the driven device 300 may retract into the housing 100 through the aperture 110 with rotation of the drive mechanism 200. In an alternative, the second state may be that the electromagnetic coil is in a second power-on state, in the second power-on state, the electromagnetic coil generates a second magnetic force on the moving body 230, so as to drive the moving body 230 to move in the second direction, and the moving body 230 moves in the second direction, and finally can drive the base 210 to reset, so that the driven device 300 is finally retracted into the housing 100 along with the housing 100, and finally hidden inside the housing 100 is achieved. The energization current of the electromagnetic coil in the first state is opposite to the energization current of the electromagnetic coil in the second state.

Of course, in another alternative, the second state may be the solenoid being in a de-energized state. When the electromagnetic coil is in the power-off state, the magnetic action of the electromagnetic coil on the moving body 230 disappears, and the moving body 230 can reset and move under the action of its own gravity, and finally the base 210 is driven to drive the driven device 300 to move into the housing 100.

In the embodiment of the present invention, the moving body 230 may be a magnetic member, and is capable of sliding in the slide rail 211 by receiving a magnetic force in a magnetic field generated by the electromagnetic coil after being energized. Of course, the moving body 230 may be made of other materials capable of being magnetically attracted, for example, the moving body 230 may be a ferrous member.

According to the electronic device disclosed by the embodiment of the invention, by improving the structure of the electronic device in the prior art, the driving mechanism 200 comprises the base 210, the electromagnetic coil and the moving body 230, and when the electromagnetic coil is in the first state, the electromagnetic coil drives the moving body 230 to move, so that the base 210 drives the driven device 300 to extend out of the shell 100 through the through hole 110, and when the electromagnetic coil is in the second state, the electromagnetic coil drives the moving body 230 to move, so that the base 210 drives the driven device 300 to retract into the shell 100 through the through hole 110. As can be seen from the above process, the driving mechanism 200 in the electronic device disclosed in the embodiment of the present invention has a simple structure, and does not need a complicated transmission mechanism or driving motor, so that the structure of the electronic device can be simplified.

In the embodiment of the present invention, the electromagnetic coil may be disposed at various positions as long as the movable body 230 can be driven. To improve the compactness of the structure, in the alternative, the solenoid may be disposed within the slide 211.

In order to facilitate the opening of the slide track 211, in the embodiment of the present invention, both ends of the slide track 211 may be open ends. This configuration also facilitates assembly of the other components of the drive mechanism 200 within the slide 211. Optionally, the driving mechanism 200 disclosed in the embodiment of the present invention may further include a blocking block 220, and the blocking block 220 may block the opening end, so as to prevent the moving body 230 or other components of the driving mechanism 200 from falling off. In a specific embodiment, the number of the blocking blocks 220 is two, and two blocking blocks 220 block two open ends respectively. Meanwhile, the blocking block 220 can prevent foreign substances (e.g., dust) from entering the slide 211, thereby affecting the movement of the moving body 230 in the slide 211.

In an optional scheme, the electronic device disclosed in the embodiment of the present invention further includes a first elastic member 400, the first elastic member 400 is disposed in the sliding channel 211, and the first elastic member 400 is elastically supported between the moving body 230 and the electromagnetic coil, and specifically, the electromagnetic coil may be fixed in the sliding channel 211. The first elastic member 400 may be deformed according to the movement of the moving body 230, so that the moving body 230 may be conveniently reset after the driving force of the electromagnetic coil to the moving body 230 is cancelled. Specifically, the first elastic member 400 may be connected to the moving body 230, for example, one end of the first elastic member 400 may be bonded to the moving body 230, thereby ensuring that the first elastic member 400 can apply an elastic force to the moving body 230 more stably. Specifically, both ends of the first elastic member 400 may be elastically positioned between one block piece 220 and the moving body 230.

In the case that the electronic apparatus disclosed in the embodiment of the present invention includes the first elastic member 400, in another alternative, the electronic apparatus disclosed in the embodiment of the present invention may further include a second elastic member 500, one end of the second elastic member 500 is positioned in the slide 211, and the other end of the second elastic member 500 is in elastic contact with the moving body 230 and stretches with the movement of the moving body 230. In this case, two sides of the moving body 230 are respectively located at the first elastic member 400 and the second elastic member 500, and the first elastic member 400 and the second elastic member 500 are both located in the slide 211, in this case, the movement of the moving body 230 can enable the first elastic member 400 or the second elastic member 500 to be elastically deformed, so as to facilitate the movement of the moving body 230 in the slide 211, and meanwhile, the deformation of the first elastic member 400 or the second elastic member 500 can reduce the inertia of the moving body 230, and finally, the rotation of the base 210 can be more stable. Specifically, both ends of the second elastic member 500 may be elastically positioned between the other block piece 220 and the moving body 230.

In the embodiment of the present invention, the kinds of the first elastic member 400 and the second elastic member 500 may be various, and the first elastic member 400 and the second elastic member 500 may be a coil spring, an elastic metal bent piece, or the like, and the embodiment of the present invention is not limited to the specific kinds of the first elastic member 400 and the second elastic member 500. In an alternative, at least one of the first elastic member 400 and the second elastic member 500 is a coil spring.

Alternatively, the moving body 230 may be a spherical rolling body or a columnar rolling body, and the specific type of the moving body 230 is not limited in the embodiment of the present invention.

In order to improve the driving efficiency, in an alternative scheme, the slide 211 may be a circular arc slide, in which case the moving body 230 moves relative to the base 210 with a circular arc track, specifically, the center of a circle of the circular arc track is on the rotation axis of the base 210.

In the embodiment of the present invention, the base 210 has a projection in a direction perpendicular to the rotation axis of the base 210 in a semicircular shape. The rotational axis of the base 210 is disposed adjacent to the center of the semicircle. In the case where the driving mechanism 200 is retracted out of the housing 100, the base 210 is in sealing engagement with the through hole 110, so that the waterproof and dustproof performance of the electronic apparatus can be improved.

In an optional scheme, base 210 can include back of the body top surface and bottom surface that distributes and connect the side between top surface and bottom surface, and the side includes first straight section and curved surface section, and the one end of straight section links to each other with the one end of curved surface section, and the other end of straight section links to each other with the other end of curved surface end, and under solenoid was in the second state, straight section and perforation shutoff cooperation to improve electronic equipment's waterproof dirt-proof performance.

The cover in the second position is clear of the aperture 110 in preparation for the driven device 300 to extend out of the housing 100.

Specifically, one end of the cover may be hinged to the housing 100, the other end of the cover may be engaged with the housing 100 by fastening, and when the cover is in the second position, the cover is disengaged from the housing 100, thereby opening the through hole 110, and when the cover is in the first position, the cover is engaged with the housing 100 by fastening.

In another alternative, the cover is slidably disposed on the housing 100 to switch between the first position and the second position. Specifically, the housing 100 may be provided with a sliding rail, and the sealing cover is in sliding fit with the sliding rail, so as to achieve guiding of movement in the position switching process, thereby facilitating the operation and control of the user.

As described above, the electromagnetic coil may be provided on the slide 211, so that the compactness of the drive mechanism 200 can be improved. Of course, the electromagnetic coil may be disposed at other positions of the base 210 as long as the electromagnetic coil can generate a driving force to the movable body 230 in a state of being energized, so that the movable body 230 moves in the slide 211. For example, the base 210 may be formed with a mounting groove, and the electromagnetic coil may be fitted in the mounting groove.
