Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, 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 belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention provides an electronic device. The electronic device may be a portable electronic device, which may be, for example, a smartphone, a tablet, a smart watch, or the like.

Referring to fig. 1, a structure of an electronic device according to an embodiment of the invention is shown. The electronic device comprises a housing 10 provided with a containing cavity 110, a function module 20 and a rotating disk 30, wherein the function module 20 is carried and fixed on the rotating disk 30, and the rotating disk 30 is arranged in the containing cavity 110 and is rotatably connected with the housing 10, so that the function module 20 can be selectively positioned in the housing 10 or extend out of the housing 10 through the containing cavity 110.

The outer shape of the case 10 is not limited. The position of the accommodating chamber 110 on the housing 10 is flexibly set as required. Referring to fig. 1, in the present embodiment, the case 10 is taken as an example of a rectangular parallelepiped, and the accommodating cavity 110 is disposed at one end of the case 10 in the length direction. More specifically, the receiving cavity 110 opens at a top end 120 of the housing 10. When the user holds the electronic device and is in normal use, the top end 120 is the high point of the device in the vertical direction. The accommodating chamber 110 extends in a length direction of the housing 10, that is, an axial direction (i.e., a depth direction) of the accommodating chamber 110 coincides with the length direction of the housing 10, that is, both in a vertical direction a in fig. 1. It is understood that when the receiving chamber 110 is disposed at the side of the housing 10, the axial direction of the receiving chamber 110 coincides with the width direction of the housing 10, i.e., the horizontal direction B in fig. 1.

The rotary disk 30 is rotatably disposed in the accommodating chamber 110 of the housing 10 through a pivot 310 so as to be capable of moving the function module 20. As shown in fig. 2 and 3, the rotary disk 30 has an initial position with respect to the housing 10 in which the rotary disk 30 is entirely located within the housing 10 and the function module 20 is in the first position located within the housing 10. As shown in fig. 4 and 5, the rotary plate 30 has a rotated-out position with respect to the housing 10, in which the part of the rotary plate 30 is rotated to the outside of the housing 10, and the rotary plate 30 extends the function module 20 out of the housing 10 to a second position located outside the housing 10. From the initial position to the rotated-out position, the function module 20 extends out of the housing 10 through the accommodating chamber 110. In this way, the functional module 20 can be hidden inside the housing 10 when not in use and can be extended out of the housing 10 when in use. Thus, the front surface 101 or the back surface 102 of the electronic device may not be provided with the mounting hole of the functional module 20, thereby facilitating the improvement of the screen occupation ratio of the electronic device, and the electronic device can really realize a full screen or a very narrow frame. The functional module 20 includes at least one of a camera module, a flash, an earpiece, a microphone, an iris recognition module, a face recognition module, an ambient light sensor, and an IR (Infrared) sensor.

In this embodiment, the functional module 20 is hidden and extended by the rotation of the rotary disk 30. Compared with the telescopic structure of the traditional scheme, the structural design requirement on the rotating disc 30 is simple, and the space required by rotation is relatively small, so that the telescopic structure has obvious advantages.

To hide and extend the functional module 20, the rotary disk 30 needs to be capable of being driven to rotate. Furthermore, when the rotating disc 30 is in the initial position, the function module 20 is located inside the housing 10 in the first position, and it is required that the rotating disc 30 and the function module 20 are kept stationary. When the rotary plate 30 is in the rotated position, the rotary plate 30 and the function module 20 are also required to be kept stationary, so that the function module 20 can work normally. Therefore, a set of driving structure is needed to satisfy the above objectives. In addition, the structure of the driving structure is simple as much as possible, the precision requirement is low, the occupied space of the whole machine is small as much as possible, and the purpose of reducing the cost of the whole machine is achieved.

To this end, the inventors of the present invention propose a concept of using electromagnetic control instead of mechanical control to achieve the above-described object at the same time. The specific concept is as follows, set up magnetic assembly on rotary disk 30, and inside casing 10, then set up the driving electromagnet subassembly in the outside of rotary disk 30 then, when the driving electromagnet subassembly produces magnetism, driving electromagnet subassembly and magnetic assembly interact power driving rotary disk 30 rotate, and then drive function module 20 and rotate, make function module 20 be located casing 10 or outside the casing 10, so utilize magnetic force can realize stretching out and hiding of function module 20, the mechanical component part of drive structure only comprises electro-magnet and magnetic element, more set up the extending structure that the structure is complicated, the structure is simplified greatly, and the cost is lower.

Further, the driving electromagnet assembly specifically includes a positioning electromagnet and a guiding electromagnet that interact with the magnetic assembly, and the positioning electromagnet and the guiding electromagnet are arranged in an arc around the rotating disk 30. In this way, by controlling the currents of the positioning electromagnet and the guiding electromagnet, the positioning electromagnet can attract the magnetic assembly to fix the rotating disk 30 and provide a repulsive force acting on the magnetic assembly to drive the rotating disk 30 to rotate; meanwhile, the guide electromagnet is used for generating repulsive force acting on the magnetic assembly so as to guide the rotating direction of the rotating disk 30, so that the rotating direction of the rotating disk 30 can be controlled, and the rotating disk can be screwed out of the shell 10 or screwed into the shell 10 according to a preset direction. The following is a detailed description of the embodiments.

As shown in fig. 2, the rotating disk 30 is further provided with a first magnet 320 and a second magnet 330 at intervals to constitute a magnetic assembly. Inside the housing 10, a first electromagnet 40, a second electromagnet 50, a third electromagnet 60 and a fourth electromagnet 70 are sequentially arranged along an arc outside the rotating disk 30, wherein the first electromagnet 40 and the fourth electromagnet 70 are defined as positioning electromagnets, and the second electromagnet 50 and the third electromagnet 60 are defined as guiding electromagnets. Thus, by energizing each electromagnet to generate magnetism or cancel magnetism, and controlling the polarity of the electromagnet when generating magnetism, the purpose of rotating out and resetting the rotary disk 30 and the purpose of fixing the rotary disk 30 are achieved.

In a specific embodiment, referring to fig. 2 and 4, when the position of the rotating disc 30 is set to rotate from the initial position to the rotated-out position of the rotating disc 30, the positions of the first magnet 320 and the second magnet 330 relative to the casing 10 are just exchanged. That is, when the rotary plate 30 rotates from the initial position to the rotated-out position, the rotary plate 30 rotates 180 degrees, so that the position of the second magnet 330 relative to the housing 10 is exactly the position of the first magnet 320 relative to the housing 10 at the initial position; and vice versa. More specifically, as shown in fig. 2, when the rotary disk 30 is at the initial position, the position of the first magnet 320 is defined as the third position, and the position of the second magnet 330 is defined as the fourth position. As shown in fig. 4, when the rotary plate 30 rotates from the initial position to the rotated-out position, the first magnet 320 moves to the fourth position, and the second magnet 330 moves to the third position. As shown in fig. 2, when the rotary disk 30 is switched back to the initial position from the rotated-out position, the first magnet 320 returns to the third position, and the second magnet 330 returns to the fourth position.

In addition, referring to fig. 2, the magnetic pole of the first electromagnet 40 when energized is opposite to the magnetic pole of the first magnet 320 when the rotating disc 30 is at the initial position, or referring to fig. 4, the magnetic pole of the first electromagnet 40 when energized is opposite to the magnetic pole of the second magnet 330 when the rotating disc 30 is at the unscrewing position; referring to fig. 2, the magnetic pole of the fourth electromagnet 70 when energized faces the magnetic pole of the second magnet 330 when the rotating disk 30 is at the initial position, or referring to fig. 4, the magnetic pole of the fourth electromagnet 70 when energized faces the magnetic pole of the first magnet 320 when the rotating disk 30 is at the rotated-out position; second electromagnet 50 is adjacent to first electromagnet 40 and third electromagnet 60 is adjacent to fourth electromagnet 70.

With the above arrangement, when the rotary disk 30 is at the initial position or the rotated-out position, the first electromagnet 40 may be energized to be able to attract the first magnet 320 or the second magnet 330, so as to immobilize the rotary disk 30; the fourth electromagnet 70 is energized to generate magnetism to attract the second magnet 330 or the first magnet 320, so as to fix the rotating disk 30. The first electromagnet 40 and the fourth electromagnet 70 may exert the attracting action collectively or alternatively. When the rotating disk 30 is switched between the initial position and the rotated-out position, the rotating disk 30 can be rotated in a predetermined direction by changing the magnetism and polarity of the first electromagnet 40 and the fourth electromagnet 70, using the repulsion of the magnetic force to enable the rotating disk 30 to rotate, and then by energizing the second electromagnet 50 or the third electromagnet 60 to generate magnetism. The rotary disk 30 can be rotated or reset in a predetermined direction, so that the functional module 20 can be accurately screwed out of the housing or hidden back into the housing 10 as required; and the rotary disk 30 is positioned by magnetic force at the initial position or the unscrewing position, so that the function module 20 can be reliably kept outside the housing 10 to ensure the normal use of the function module 20, or the function module 20 is stably hidden in the housing 10.

How the rotation and resetting of the rotating disk 30 is achieved is described in further detail below in conjunction with the figures. Hereinafter, the polarity of the first magnet 320 is referred to as N-pole, and the polarity of the second magnet 330 is referred to as S-pole.

Referring to fig. 2, the rotary plate 30 is in the initial position, and the function module 20 is hidden in the housing 10. The first magnet 320 is located on the left side of the pivot 310 and the second magnet 330 is located on the right side of the pivot 310. At this time, the first electromagnet 40 is energized to generate magnetism with the polarity of S, and the fourth electromagnet 70 is energized to generate magnetism with the polarity of N. The second electromagnet 50 and the third electromagnet 60 are not energized and are nonmagnetic. Thus, first electromagnet 40 and first magnet 320 are magnetically opposed and attracted to each other, and fourth electromagnet 70 and second magnet 33 are magnetically opposed and attracted to each other. The rotary disk 30 is attracted by both the first electromagnet 40 and the fourth electromagnet 70 and is reliably fixed in the housing 10.

Referring to fig. 3, when the rotating disk 30 needs to be rotated out, the polarity of the first electromagnet 40 is changed to N. The second electromagnet 50 is not yet energized. Third electromagnet 60 is energized with the polarity S. The fourth electromagnet 40 is de-energized and demagnetized. Thus, the first electromagnet 40 and the first magnet 320 face each other in the same polarity, and a repulsive force F1 for rotating the rotary disk 30 is generated therebetween. Meanwhile, according to the principle of homopolar repulsion, the third electromagnet 60 gives a thrust T1 to the second magnet 330, so that the rotating disk 30 rotates in the counterclockwise direction, and the functional module 20 is unscrewed. The thrust T1 acts to guide the rotation direction of the rotary plate 30 and to assist the rotation, so that the third electromagnet 60 needs to be de-energized and demagnetized in time after the rotary plate 30 starts to rotate.

Referring to fig. 4, the rotating plate 30 is shown in the rotated position, and the function module 20 is located outside the housing 10. The first magnet 320 rotates to the right of the pivot 310 and the second magnet 330 rotates to the left of the pivot 31. Then, the polarity of the first electromagnet 40 is kept to be N-pole, so that the first electromagnet 40 and the second magnet 330 are attracted to each other; fourth electromagnet 70 is energized to regenerate magnetic properties with a polarity of S, causing fourth electromagnet 70 and first magnet 320 to attract each other. At the same time, the second electromagnet 50 is not energized and the third electromagnet 60 is not energized. By the above measures, the rotating disk 30 is attracted by the first electromagnet 40 and the fourth electromagnet 70 at the same time and fixed in the housing 10, so that the function module 20 is fixed in a position in which it can be controlled to perform its function.

Referring to fig. 5, when the functional module 20 needs to be hidden in the housing 10, the rotary disk 30 is rotated and reset. In this embodiment, the rotation direction of the rotating disk 30 when it is rotated out is counterclockwise, and the rotation direction when it is reset is clockwise. At this time, the first electromagnet 40 is de-energized to remove magnetism; energizing the second electromagnet 50 to produce magnetism with a polarity of S; de-energizing third electromagnet 60 to remove magnetism; the polarity of fourth electromagnet 70 is changed to the N polarity. Thus, according to the principle of homopolar repulsion, the second electromagnet 50 generates a pushing force T2 to the second magnet 330, and the fourth electromagnet 70 generates a repelling force F1 to the first magnet 320, so that the rotating disk 30 rotates along the pointer and finally resets to the position shown in fig. 2. In the position shown in fig. 2, the first electromagnet 40 and the fourth electromagnet 70 can be used to attract the rotating disc 30 to be fixed in the housing 10, which is already described above and will not be described herein again.

In the above embodiment of the present invention, the first magnet 320 and the second magnet 330 are disposed on the rotating disk 30, and the first electromagnet 40, the second electromagnet 50, the third electromagnet 60, and the fourth electromagnet 70 are disposed outside the rotating disk 30. Wherein the first electromagnet 40 and the fourth electromagnet 70 are used to attract the fixed rotating disk 30 when the rotating disk 30 is at the initial position or the rotated-out position, on the one hand, and also to provide a repulsive force for rotating the rotating disk 30, on the other hand. And the second electromagnet 50 and the third electromagnet 60 are used to provide a thrust force acting on the rotating disk 30 to guide the rotating direction of the rotating disk 30. Above-mentioned process can be realized through the control of electric current, and the mechanical component part of drive structure only comprises electro-magnet and magnet, and the extending structure that sets up the structure complicacy simplifies greatly, and the cost is lower.

Note that the control method of each electromagnet when the rotary disk 30 is rotated out and reset is not limited to the above-described method. For example, when the rotary disk 30 needs to be rotated out of the initial position, the first electromagnet 40 may generate a repulsive force to the first magnet 320, and the second electromagnet 50 may generate an attractive force to the first magnet 320 to guide the rotary disk 30 to rotate in the counterclockwise direction. When the rotating disk 30 is reset from the rotated-out position, the third electromagnet 60 may generate an attraction force to guide the rotating disk 30 to rotate in the clockwise direction and reset.

In the above embodiment, the number of magnets in the magnetic assembly, the number of positioning electromagnets in the driving electromagnet assembly, and the number of guiding electromagnets are 2 as an example. However, their number may be more than 2. For example, the first magnet 320 may be a plurality of small magnets.

In addition, in other embodiments, the number of magnets in the magnetic assembly may be less than 2. For example, only the first magnet 310 may be provided. Thus, when the rotary disk 30 is rotated out, the first electromagnet 40 generates a repulsive force acting on the first magnet 310, the second electromagnet 50 provides an attractive force to guide the rotary disk 30 to rotate in the counterclockwise direction, and the second electromagnet 50 is deenergized and demagnetized after the rotary disk 30 starts to rotate in the counterclockwise direction.

Similarly, the number of positioning electromagnets may be less than 2, or only one positioning electromagnet may be provided, such as only the first electromagnet 40. When the rotating disc 30 is screwed out, the first electromagnet 40 can be used for generating repulsive force to rotate the rotating disc 30, and the third electromagnet 60 can be used for generating thrust for guiding the rotating disc 30 to rotate anticlockwise; the first electromagnet 40 may be used to generate a repulsive force when reset, and the third electromagnet 60 may be used to provide an attractive force to guide the rotating disk 30 to rotate in the clockwise direction. When the rotary plate 30 is at the initial position or the rotated position, the rotary plate 30 is fixed by the first magnet 310 and the first electromagnet 40 or the fourth electromagnet.

Similarly, the number of guidance electromagnets may also be only one. If only the second electromagnet 50 is provided, when the rotating disk 30 is rotated out, the first electromagnet 40 may be used to generate a repulsive force to rotate the rotating disk 30, and the second electromagnet 50 may be used to provide an attractive force to guide the rotating disk 30 to rotate in the counterclockwise direction. When the rotating disk 30 is reset, the fourth electromagnet 70 generates a repulsive force to rotate the rotating disk 30, and the second electromagnet 50 provides a thrust force to guide the rotating disk 30 to rotate in the clockwise direction.

The first magnet 320 and the second magnet 330 are disposed on the same side of the surface of the rotating disk 30. The first magnet 40 and the second magnet 50 each protrude a certain height from the rotating disk 30. In order to facilitate the installation into the casing 10, as shown in fig. 2, in some embodiments, the protruding heights of the first magnet 320 and the second magnet 330 with respect to the surface of the rotating disk 10 are set to be uniform, and an insulating medium layer 340 is further disposed on the rotating disk 30 between the first magnet 320 and the second magnet 330, and the thickness of the insulating medium layer 340 is equal to the protruding height. By the above measures, the area between the first magnet 320 and the second magnet 330 is a plane, so that when the rotating disk 30 is placed in the casing 10, the plane also plays a certain supporting role for the rotating disk 10, and the stability of the mechanism is improved.

The insulating dielectric layer 340 is a dielectric layer having an insulating ability, and the type thereof is not limited. Preferably, the insulating medium layer 340 is an insulating tape. That is, an insulating tape of a sufficient thickness is adhered between the first magnet 320 and the second magnet 33 to form an insulating medium layer.

The shape of the rotary disk 30 is not limited, and may be square, triangular, semicircular, etc., as long as it can rotate around the pivot 310 to rotate the function module 20 out of the housing 10 or hide the function module in the housing 10. In a preferred embodiment, the rotating disc 30 is semi-circular. The semicircular rotary plate 30 is more stable when rotated than other shapes such as a triangle, and the appearance presented when the rotary plate 30 is rotated out of the housing 10 is more beautiful. In addition, compared with other shapes, such as a triangle, the semicircular design of the rotary disk 30 can ensure better filling performance when the rotary disk 30 is positioned in the casing 10, namely, the rotary disk 3 occupies the whole rotation space of the casing 10, thereby preventing foreign matters from entering the accommodating cavity 110 and avoiding blockage.

As shown in fig. 2, when the rotating disk 30 has a semicircular shape, the first magnet 320, the second magnet 330, and the insulating medium layer 340 are sequentially disposed along the semicircular edge of the rotating disk 30. Therefore, a larger area is reserved in other areas of the rotating disk 30, which is beneficial to setting a functional module with a larger size and specification.

As shown in fig. 2, two ends of the 180-degree central angle of the rotating disk 30 are respectively defined as a first end 301 and a second end 302, wherein the first magnet 320 is fixed to the first end 301, the second magnet 330 is fixed to the second end 302, and the pivot 310 is located at the midpoint of the line connecting the first end 301 and the second end 302. That is, the first magnet 320 and the second magnet 330 are fixed to one of opposite ends of the rotating disk 30, respectively. The rotary disk 30 rotates around the pivot 310, so that when the rotary disk 30 is rotated out of the housing 10 and the first electromagnet 40 gives the first magnet 320 a repulsive force F1, the distance from the action line of the repulsive force F1 to the pivot 310 is large, so that the rotary disk 30 is more easily pushed to rotate, the consumed energy is small, and the standby capability of the electronic device is improved. Similarly, when the rotary disk 30 is reset, and the fourth electromagnet 70 gives the repulsive force F2 to the first magnet 320, the distance from the action line of the repulsive force F2 to the pivot 310 is large, so that the rotary disk 30 is more easily pushed to rotate, the consumed energy is small, and the standby capability of the electronic device is improved.

Referring to fig. 2, the pivot 310 and the function module 20 are arranged along the radial direction of the rotating disc 30, wherein the pivot 310 is closer to the center C of the rotating disc 30, and the connecting line between the pivot 310 and the function module 20 is parallel to the axial direction of the accommodating chamber 110 when the rotating disc 30 is at the initial position shown in fig. 2. Referring to fig. 1 in combination, the axial direction of the receiving chamber 110 coincides with the length direction of the housing 10. The pivot 310 and the function module 20 are also arranged in an up-and-down manner. With the above arrangement, referring to fig. 4, when the rotary disc 30 is rotated out of the housing 10, the rotary disc 30 rotates by 180 degrees, and the function module 20 rotates to a position right above the pivot 310, so that the distance from the function module 20 to the edge of the housing 10 is the largest. Thus, on the one hand, the function module 20 is more easily shot from the outside scene farther from the housing. On the other hand, the above arrangement also makes the functional module 20 more easily and completely screwed out of the housing 10 under the condition that the specification of the rotary disk 30 is not changed and the range of the rotation angle is not changed, which is beneficial to arranging the functional module 20 with a larger size specification.

Referring to fig. 1, the electronic device includes a front surface 101 and a back surface 102 disposed opposite to each other, wherein the front surface 101 has a screen 1011, the functional module 20 is a camera module, and the functional module 20 is opposite to the front surface 1011. That is, in some embodiments, the electronic device has a front camera, and the rotary disk 30 is used to extend and hide the front camera, so that the front space is not occupied, and therefore the electronic device can have a higher screen occupation ratio without changing the external dimensions. In addition, the rotating disc 30 can be screwed out and reset by utilizing current control, and the mechanical component of the driving structure of the rotating disc 30 only consists of an electromagnet and a magnet, so that the structure is greatly simplified and the cost is lower compared with a telescopic structure with a complex structure. Of course, in other embodiments, the functional module 20 may also be a rear camera module, and the functional module 20 is disposed opposite to the back surface 102.

Referring to fig. 1, in some embodiments, the pivot 310 is fixed to one of the housing 10 and the rotary plate 30, and the other of the housing 10 and the rotary plate 30 is provided with a hole 103 detachably engaged with the pivot 310. For example, the pivot 310 is fixed to the rotary plate 30, and the housing 10 has a hole 103 for engaging with the pivot. Therefore, the first magnet 320, the second magnet 330, the functional module 20 and the like are fixed on the rotating disk 30 to form a detachable module, and an assembler can assemble the first magnet 320, the second magnet 330 and the functional module 20 into a whole in advance and then install the whole into the shell 10, so that the modular assembly degree is improved.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
