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 a few embodiments of the invention, and not all embodiments. 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 5, an embodiment of the invention discloses an electronic device, which includes a housing 100, a telescopic module 200, a first elastic element 300, and a limiting mechanism 400.

The housing 100 is a base member of the electronic device, the housing 100 can provide a mounting base for other components of the electronic device, the housing 100 is provided with an opening 110, the opening 110 is usually provided on a frame of the housing 100, and the opening 110 can be passed through by the retractable module 200, so that the retractable module 200 can enter and exit the housing 100. The telescopic module 200 is movably disposed on the housing 100, the telescopic module 200 can move between an extended position and a retracted position through the opening 110, and at least a portion of the telescopic module 200 is located outside the housing 100 when the telescopic module 200 is in the extended position; with the pantograph 200 in the retracted position, the pantograph 200 is located within the housing 100.

Specifically, this flexible module 200 can include at least one in camera, sensor, fingerprint identification module, acoustics device and the light filling lamp, can also include other parts that need stretch out casing 100 and carry out work certainly. The telescopic module 200 is provided with a limiting convex edge 210 and a limiting groove 220, and the limiting convex edge 210 is located between the opening 110 and the limiting groove 220.

The housing 100 includes a seat body 120, the seat body 120 may be fixed in the inner cavity of the housing 100 by a fastener such as a screw, and may also be fixedly connected in the inner cavity of the housing 100 by an adhesion manner, of course, the seat body 120 may also be integrally formed with the housing 100 by an injection molding manner. The first elastic element 300 abuts between the retractable module 200 and the base 120, the first elastic element 300 is connected to the retractable module 200, and the first elastic element 300 can drive the retractable module 200 to move toward the extended position, so that at least a portion of the retractable module 200 is located outside the housing 100.

The limiting mechanism 400 includes an electromagnet 410, a second elastic member 420 and a limiting block 430, the electromagnet 410 is fixedly disposed in the casing 100, the electromagnet 410 is connected to one end of the second elastic member 420, the other end of the second elastic member 420 is connected to the limiting block 430, and the electromagnet 410 and the limiting block 430 can be magnetically coupled. Specifically, under the circumstances that the electromagnet 410 is electrified, the electromagnet 410 can attract the limiting block 430, at this time, the second elastic member 420 is compressed, under the circumstances that the electromagnet 410 is powered off, the magnetic force between the electromagnet 410 and the limiting block 430 disappears, and at this time, the second elastic member 420 is restored, so that the limiting block 430 is driven to move, and therefore the limiting block 430 is switched between the limiting fit and the separation with the limiting groove 220. Of course, under the condition that the electromagnet 410 is powered on, the electromagnet 410 and the limiting block 430 can repel each other, at this time, the second elastic member 420 is stretched, under the condition that the electromagnet 410 is powered off, the magnetic force between the electromagnet 410 and the limiting block 430 disappears, and at this time, the second elastic member 420 is restored, so that the limiting block 430 is driven to move, and the limiting block 430 is switched between the limiting fit and the separation with the limiting groove 220.

Optionally, the limiting block 430 may be an iron member, a permanent magnet member, or an electromagnetic member, so that the electromagnet 410 and the limiting block 430 can be matched with each other by magnetic attraction, thereby improving the stability of the limiting mechanism 400 in limiting the telescopic module 200.

When the telescopic module 200 is in the retracted position, the limiting block 430 is in limiting fit with the limiting groove 220 in the telescopic direction of the telescopic module 200, so that the telescopic module 200 can be kept in the housing 100; under the condition that the telescopic module 200 is located at the extending position, the limiting block 430 is separated from the limiting groove 220, so that the telescopic module 200 can be at least partially located outside the housing 100 under the driving action of the first elastic member 300, and the limiting groove 220 is in limiting fit with the housing 100 in the extending direction of the telescopic module 200, so that the telescopic module 200 does not completely extend out of the housing 100, and the telescopic module 200 is prevented from completely extending out of the housing 100 and being difficult to retract back into the housing 100 again, thereby improving the stability and reliability of the telescopic movement of the telescopic module 200.

In a specific working process, when the telescopic module 200 needs to work, a user can control the electromagnet 410 to be powered on or powered off in a way of operating a button or controlling voice control, so that the limiting block 430 is separated from the limiting groove 220 under the action of the second elastic member 420 or magnetic force, at this time, the first elastic member 300 drives the telescopic module 200 to move towards the extending position, so that at least part of the telescopic module 200 is located outside the shell 100, and thus preparation is made for the work of the telescopic module 200. After the telescopic module 200 finishes working, the user presses the telescopic module 200 to move the telescopic module 200 to the retracted position, at this time, the limiting block 430 is in limited cooperation with the limiting groove 220 again, so that the telescopic module 200 retracts into the housing 100, thereby realizing hiding in the housing 100, and the limiting mechanism 400 and the first elastic member 300 are restored to the state before the telescopic module 200 extends out, so that the telescopic module 200 extends out again. Such reciprocation enables extension and retraction of the telescopic module 200 with respect to the housing 100.

As can be seen from the above working process, the electronic device disclosed in the embodiment of the present invention can realize the operation or hiding of the telescopic module 200 by the position conversion of the telescopic module 200 (from the inside of the housing 100 to the outside of the housing 100 and from the outside of the housing 100 to the inside of the housing 100) on the premise of having the functional devices on the telescopic module 200, the arrangement of the telescopic module 200 does not occupy the area on the electronic device where the display screen is arranged, and the further increase of the screen occupation ratio of the electronic device is not limited, so that the screen occupation ratio of the electronic device can be increased. Meanwhile, the scheme can avoid the notch from being formed in the display screen of the electronic equipment, so that the shape of the display screen is protected, the integrity of the display screen is ensured, the display effect of the display screen is better, and the user experience of the electronic equipment is improved. Therefore, the electronic equipment disclosed by the embodiment of the invention can solve the problem that the screen of the electronic equipment is small in occupied ratio.

In the embodiment of the present invention, when the user presses the telescopic module 200, the telescopic module 200 slides relative to the limiting block 430 in the process that the telescopic module 200 moves toward the retracted position, and when the limiting groove 220 slides to the position opposite to the limiting block 430, the limiting block 430 is clamped into the limiting groove 220 under the action of the second elastic member 420 or the magnetic force, so as to achieve the limiting fit. In order to make the friction force during the sliding of the telescopic module 200 relative to the limiting block 430 smaller, so that the telescopic module 200 and the limiting block 430 can slide smoothly and continuously, in an alternative embodiment, one end of the limiting block 430 facing the telescopic module 200 may be a spherical end 431, the limiting groove 220 may be adapted to the spherical end 431, the spherical end 431 slides into the limiting groove 220 when the telescopic module 200 moves towards the retracted position, and the spherical end 431 slides out of the limiting groove 220 when the telescopic module 200 moves towards the extended position.

In the sliding process of the telescopic module 200 relative to the limiting block 430, the spherical end 431 is less in contact with the telescopic module 200, and the spherical end 431 is spherical, so that the spherical end 431 can reduce friction force in the sliding process of the telescopic module 200 relative to the limiting block 430, so that the telescopic module 200 and the limiting block 430 can better slide, the telescopic module 200 and the limiting block 430 can stably and continuously slide, the phenomenon of jamming and unsmooth in the moving process of the telescopic module 200 towards the retraction position is avoided, and the stability of the telescopic movement of the telescopic module 200 is further improved.

Optionally, the limiting mechanism 400 may further include a housing 440, the second elastic member 420 and the limiting block 430 are at least partially located in the housing 440, and the housing 440 is in sliding fit with the limiting block 430, so that the limiting block 430 can stably and stably move, the limiting block 430 is prevented from shaking, or the second elastic member 420 is inclined due to shaking of the limiting block 430, thereby preventing the limiting mechanism 400 from failing, and further improving reliability of the limiting mechanism 400.

Further, the limiting block 430 may include a limiting body 432, the spherical end 431 may be disposed on the limiting body 432, the limiting body 432 is in sliding fit with the casing 440, a sliding-out limiting portion 441 is disposed at a port of the casing 440, and the sliding-out limiting portion 441 and the limiting body 432 may be in limiting fit in a sliding direction of the limiting body 432. Under the condition, the sliding-out limiting part 441 limits the limiting body 432 to slide out of the shell 440, so that the limiting block 430 is at least partially positioned in the shell 440, the limiting block 430 is prevented from being difficult to move into the shell 440 after being completely slid out of the shell 440, and the reliability of the limiting mechanism 400 is improved. Meanwhile, after the limiting block 430 completely slides out of the housing 440, the limiting block 430 is inclined due to friction in the process that the telescopic module 200 moves towards the retracted position, and the limiting block 430 is prevented from being difficultly matched with the limiting groove 220 in a limiting manner, so that the limiting stability of the limiting mechanism 400 can be improved.

As described above, the second elastic member 420 can drive the limiting block 430 to move, and particularly, the second elastic member 420 can be in a natural state in a case where the limiting block 430 is in limiting engagement with the limiting recess 220, and the second elastic member 420 can be in a compressed state in a case where the limiting block 430 is separated from the limiting recess 220. That is to say, under the condition that the electromagnet 410 is powered on, the electromagnet 410 can attract the limiting block 430, at this time, the second elastic member 420 is compressed, under the condition that the electromagnet 410 is powered off, the magnetic force between the electromagnet 410 and the limiting block 430 disappears, and at this time, the second elastic member 420 is restored, so that the limiting block 430 is driven to move, and therefore the limiting block 430 is switched between the limiting fit and the separation with the limiting groove 220. In this case, the electromagnet 410 is only needed to be powered on when the telescopic module 200 needs to be extended, so as to avoid that the electromagnet 410 is powered on all the time, which results in larger power consumption of the electronic device. It should be noted that the shortened state of the second elastic member 420 refers to a state when the second elastic member 420 is compressed, the natural state of the second elastic member 420 refers to an initial state of the second elastic member 420, and in the embodiment of the present invention, the natural state of the second elastic member 420 may also refer to an extended state of the second elastic member 420 compared to the shortened state.

Specifically, the first elastic member 300 may be a first spring, which has a simple structure, is convenient to set, and has a low cost, so that the structural complexity and the cost of the electronic device can be reduced. Further, the second elastic member 420 may also be a second spring, so as to further reduce the structural complexity and cost of the electronic device.
