Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram illustrating a terminal with a swing-out camera module according to an exemplary embodiment, where the terminal includes: a middle frame 120 and a swing-out camera module 140.

A through hole 122 is formed in one edge of the middle frame 120 facing the inside of the terminal, a rotating shaft 124 is arranged on the through hole 122, the rotating shaft 124 is arranged along the width direction of the middle frame 120, and a screw-out type camera module 140 is connected to the rotating shaft 124; optionally, the middle frame 120 includes an upper side edge, a lower side edge, a left side edge, and a right side edge; the through-hole 122 may be provided on at least one of the side edges, as exemplified in fig. 1 by the upper side edge.

The swing-out camera module 140 includes: two camera housings 142 and a telescopic module 144 are symmetrically arranged. As an example of the present embodiment, the rotation axis 124 is located at the midpoint of the edge, and the symmetrical arrangement is to use the center line of the front surface where the rotation axis 124 is located as the symmetrical line.

One end of each of the two camera housings 142 is connected to the rotating shaft 124; the telescopic module 144 is disposed right below the rotating shaft 124; the telescopic module 144 is connected to the bottom of the two camera housings 142 through a connecting rod 11.

The telescopic module 144 is used for pushing the two camera shells 142 to rotate out of the middle frame by taking the rotating shaft as a circle center in a power-on state. That is, when the telescopic module 144 is in the power-on state, the telescopic module 144 pushes the two camera housings 142 to make an arc motion around the rotating shaft 124 through the connecting rod 11, so as to rotate the camera housings 142 out of the middle frame 120.

Alternatively, the user may manually push the camera housings 142 to make the two camera housings 142 perform arc motion around the rotation shaft 142, and rotate the two camera housings back to the middle frame 120.

In summary, the terminal provided in this embodiment is provided with the screw-out type camera module, and the screw-out type camera module is arranged inside the terminal, so that the space of a screen on the terminal is not occupied, the screen occupation ratio of the terminal is improved, and the comprehensive screen design of the terminal is realized; in addition, the shell of making a video recording uses the pitch arc as the movement track in this back-out formula module of making a video recording, turns into the angle displacement with linear displacement to can realize the back-out of the module of making a video recording more fast.

Based on fig. 1, in the swing-out type camera module, the telescopic module 144 may include the following two types:

FIG. 2 illustrates a schematic structural diagram of an electromagnetic telescoping module provided in an exemplary embodiment; this flexible module of electromagnetism includes: a guide bar 21 and a core frame 22;

both ends of the guide bar 21 are provided with a first guide bar base 31 and a second guide bar base 32. The first guide rod base 31 is arranged at one end close to the rotating shaft 124, and the second guide rod base 32 is arranged at one end far away from the rotating shaft 124; at least one of the first and second guide bases 31 and 32 is provided with a magnet 33, as shown in fig. 3. Alternatively, the first and second guide bases 31 and 32 are fixed to the side of the rear surface of the terminal housing facing the inside of the terminal.

The magnetic core bobbin 22 is disposed between the first guide base 31 and the second guide base 32; at least one first connecting rod bracket 41 is further arranged outside the magnetic core framework 22, and the first connecting rod bracket 41 is connected to the bottoms of the two camera shells 142 through the connecting rod 11; inside the core former 22, n coils 42 wound in a direction perpendicular to the guide rods are provided.

Alternatively, as shown in fig. 2 and 3, the magnetic core bobbin 22 may include a cylindrical case 43, the cross section of the cylindrical case 43 is in a ring shape composed of two concentric circles, a sealed space between an inner case and an outer case of the cylindrical case 43 is in a hollow state, and n coils 42 provided inside the magnetic core bobbin 22 are in the sealed space and wound on the inner case of the cylindrical case 43; wherein n is a positive integer.

The outside of the outer shell of the magnetic core framework 22 is also provided with two symmetrical first connecting rod brackets 41, and optionally, the two first connecting rod brackets 41 can be integrated with the cylindrical shell 43; alternatively, the first link holder 41 may be fixed to the cylindrical housing 43 by mechanical means. For example, the magnetic core bobbin 22 shown in fig. 3 includes two symmetrical first link holders 41, and the two first link holders 41 are integrated with the cylindrical housing 43.

The magnetic core frame 22 is sleeved on the guide rod 21 and is positioned between the first guide rod base 31 and the second guide rod base 32, and can reciprocate. The core former 22 is a high permeability material. Alternatively, the core former 22 may include any one of silicon steel, iron oxide, permalloy.

The core bobbin 22 is adapted to move along the guide bar in a direction approaching the first guide bar base 31 when the coil 42 is in the first energized state. When the coil 42 is in the first energized state, the coil 42 generates an electromagnetic field, which can generate an action of repulsion or attraction with the magnet 33 to push the magnetic core frame 22 to move toward the first guide rod base 31, so that the connecting rod 11 connected to the first connecting rod support 41 pushes the camera housing 142 to make an arc motion around the rotating shaft 124, and the camera housing 142 is rotated out of the middle frame 120.

Optionally, the magnetic core bobbin 22 is further configured to move along the guide rod to a direction close to the second guide rod base when the coil 42 is in the second energized state; the electromagnetic field generated by the coil 42 in the second energized state is opposite in direction to the electromagnetic field generated by the coil 42 in the first energized state.

The coil 42 is configured to generate a first electromagnetic field in a first power-on state, and the first electromagnetic field interacts with the magnetic field of the magnet 33 to push the two camera housings 142 to rotate out of the middle frame 120; alternatively, the coil 42 is used to generate a second electromagnetic field in the second powered state, and the second electromagnetic field interacts with the magnetic field of the magnet 33 to pull the two camera housings 142 to rotate back into the middle frame 120.

In some embodiments, after the camera housing 142 is rotated out of the bezel 120, the coil 42 generates an electromagnetic field when the coil 42 is in the second energized state. The electromagnetic field and the magnet 33 can generate repulsion or attraction to pull the magnetic core frame 22 to move toward the second guide rod base 32, so that the connecting rod 11 connected to the first connecting rod support 41 pulls the camera housing 142 to make an arc motion around the rotating shaft 124, and the camera housing 142 rotates back to the middle frame 120.

In some embodiments, after the camera housing 142 is rotated out of the middle frame 120, when the coil 42 is in the power-off state or the coil 42 is in the third power-on state, the user can manually push the camera housing 142 to rotate the camera housing 142 back into the middle frame 120. When the coil 42 is in the third energizing state, the intensity of the electromagnetic field generated by the coil 42 is not enough to push or pull the camera housing 142 to move, and the direction of the current in the third energizing state and the direction of the magnetic field of the electromagnetic field generated by the coil 42 are not limited in this embodiment.

In addition, a magnet 33 is further arranged in the electromagnetic telescopic module, and the arrangement of the magnet 33 on the guide rod base can adopt any one of the following three modes:

in the first case, the magnet 33 is provided on the first guide base 31, and the magnet 33 is not provided on the second guide base 32;

in the second case, the magnet 33 is not provided on the first guide base 31, and the magnet 33 is provided on the second guide base 32;

in the third case, magnets 33 are provided on both the first guide base 31 and the second guide base 32.

In the present embodiment, the magnet 33 provided on the first guide bar base 31 is referred to as a first magnet; the magnet 33 provided on the second guide bar base 32 is referred to as a second magnet.

In the first case, the winding directions of the n coils are the same; the polarity of the electromagnetic field generated by the first magnet at the end close to the magnetic core framework 22 is a first polarity, and correspondingly, the coil 42 is used for generating a first electromagnetic field at the first power-on state, and the polarity of the first electromagnetic field at the end close to the first guide rod base 31 is a second polarity; the second polarity is opposite to the first polarity, and due to opposite attraction of the magnetic properties, the coil moves in a direction approaching the first guide bar base 31 in the first energized state.

Optionally, the coil 42 is further configured to generate a second electromagnetic field in a second powered state, wherein a polarity of the second electromagnetic field at an end close to the first guide rod base 31 is the first polarity; due to the repulsion of like magnetic poles, the coil 42 moves away from the first guide rod base 31 in the second energized state.

In the second case, the winding directions of the n coils are the same; the magnetic field generated by the second magnet has a first polarity at the end close to the magnetic core frame 22, and correspondingly, the coil 42 is configured to generate a first electromagnetic field at the first power-on state, and the polarity of the first electromagnetic field at the end close to the second guide rod base 32 is the first polarity; due to the magnetic repulsion of like poles, the coil moves away from the second guide rod base 32 in the first energized state.

Optionally, the coil 42 is further configured to generate a second electromagnetic field in a second energized state, wherein the polarity of the second electromagnetic field at the end near the second guide rod base 32 is a second polarity; the second polarity is opposite the first polarity, and the coil 42 moves closer to the second guide bar base 32 in the second energized state due to the opposite attraction of the magnetic properties.

In a third case, the first electromagnetic field is attracted to the magnetic field generated by the first magnet and repelled from the magnetic field generated by the second magnet; the second electromagnetic field is mutually repulsive with the magnetic field generated by the first magnet and mutually attractive with the magnetic field generated by the second magnet. Optionally, the coils comprise a first set of coils and a second set of coils; the first group of coils is used for generating a first electromagnetic field in a first power-on state; the second set of coils is used for generating a second electromagnetic field in a second energized state. To illustrate the above case with different arrangements of the magnets 33 on the first and second

guide bar bases

31 and 32, there may be two cases:

1) the same polarity of the first magnet is opposite to that of the second magnet;

when the winding directions of the n coils are the same, taking the relative polarity between the first magnet and the second magnet as the first polarity as an example for explanation, the coil 42 is used for generating a first electromagnetic field in the first energized state, the polarity of the first electromagnetic field at the end close to the first guide rod base 31 is the second polarity, and the polarity at the end close to the second guide rod base 32 is the first polarity; the second polarity is opposite to the first polarity, and the coil 42 moves in a direction approaching the first guide bar base 31 in the first energized state due to opposite attraction and like repulsion of the magnetic poles.

Optionally, the coil 42 is further configured to generate a second electromagnetic field in a second powered state, where the polarity of the second electromagnetic field at the end near the first guide rod base 31 is a first polarity, and the polarity at the end near the second guide rod base 32 is a second polarity; the coil 42 moves in a direction to approach the second guide bar base 32 in the second energized state.

2) The first magnet is opposite to the second magnet in opposite polarity;

taking the first polarity of the first magnet and the second polarity of the second magnet as an example, in this case, the n coils 42 are configured to be composed of a first group of coils and a second group of coils;

the first group of coils is used for generating a first electromagnetic field in a first power-on state, the polarity of one end of the first electromagnetic field close to the first guide rod base 31 is a second polarity, and the polarity of one end close to the second guide rod base 32 is a first polarity; the second group of coils is used for generating a second electromagnetic field in the first power-on state, the polarity of one end of the second electromagnetic field close to the first guide rod base 31 is a first polarity, and the polarity of one end close to the second guide rod base 32 is a second polarity; due to the opposite and same magnetic polarities repelling each other, the coil 42 moves in a direction approaching the first guide bar base 31 in the first energized state.

Optionally, the first set of coils is configured to generate a second electromagnetic field in a second powered state, where a polarity of the second electromagnetic field at an end close to the first guide rod base 31 is a first polarity, and a polarity of the second electromagnetic field at an end close to the second guide rod base 32 is a second polarity; the second group of coils is used for generating a first electromagnetic field in a second electrified state, the polarity of one end of the first electromagnetic field close to the first guide rod base 31 is a second polarity, and the polarity of one end close to the second guide rod base 32 is a first polarity; the coil 42 moves in a direction to approach the second guide bar base 32 in the second energized state.

Optionally, when the first polarity is N-pole, the second polarity is S-pole; when the first polarity is S polarity, the second polarity is N polarity.

Schematically, as shown in fig. 3, magnets are disposed on both the first guide rod base 31 and the second guide rod base 32, N poles of the first magnet on the first guide rod base 31 are opposite to N poles of the second magnet on the second guide rod base 32, and winding directions of the N coils 42 are the same; when the coil 42 is in the first energized state, the polarity of the end of the coil 42 close to the first guide rod base 31 is S-pole, and the polarity of the end close to the second guide rod base 32 is N-pole; the coil 42 drives the magnetic core framework 22 to move towards the direction close to the first guide rod base 31; when the coil 42 is in the second energized state, the polarity of the end of the coil 42 close to the first guide rod base 31 is N-pole, and the polarity of the end close to the second guide rod base 32 is S-pole; the coil 42 drives the core former 22 to move together toward the second guide rod base 32.

When the coil 42 drives the magnetic core framework 22 to move together in a direction close to the first guide rod base 31, the camera shell 142 is pushed to be screwed out of the middle frame 120 by the connecting rod 11 connected to the first connecting rod bracket 41; alternatively, when the coil 42 drives the magnetic core frame 22 to move toward the second guide rod base 32, the camera housing 142 is pulled by the connecting rod 11 connected to the first connecting rod support 41 to rotate back into the middle frame 120.

In the first and third cases, after the camera housing 142 is screwed out of the middle frame 120 when the coil 42 is in the first power-on state, the coil 42 may be powered off, and at this time, the magnetic core frame 22 is attracted to the magnet of the first guide rod base 31 and can be kept stable; under the condition that the requirement of shooing is satisfied, can save the electric quantity and reduce and generate heat. Alternatively, when the camera housing 142 needs to be rotated, the coil 42 is energized in the second energized state, and after the camera housing 142 is rotated back into the middle frame 120, the coil is de-energized, and at this time, the magnetic core frame 22 is attracted to the magnet of the second guide rod base 32 and can be kept stable.

In this embodiment, the direction of the magnetic field generated by the coil 42 can be controlled by controlling the direction of the current in the coil 42.

Because in the motion process at magnetic core skeleton 22, magnetic core skeleton 22 is non-contact with magnet 33, and the flexible module of electromagnetism can directly bear the external force impact of certain degree, need not to set up the protection device of protecting against shock, can save manufacturing cost and save terminal inner space.
