The electronic device 100 further includes a first display screen 31 disposed on the front surface of the first body 10 and a second display screen 33 disposed on the front surface of the second body 20, and the display surfaces of the first display screen 31 and the second display screen 33 are oriented in the same direction as the front surfaces. In the present embodiment, the first display panel 31 and the second display panel 33 are integrally provided to constitute the display panel 30. It is understood that the first display screen 31 and the second display screen 33 may be rigid screens or flexible screens independently disposed from each other.

Referring to fig. 2-3, fig. 2 is a rear view of the electronic device shown in fig. 1, and fig. 3 is an exploded view of the electronic device shown in fig. 1. The electronic apparatus 100 further includes a driving mechanism 40, a first photographing device 50, and a controller 60. The first photographing device 50 is disposed on the back surface of the first body 10 and electrically connected to the controller 60. The second body 20 is provided with a light-transmitting area 201 corresponding to the first photographing device 50. A first through hole 21 is formed in the light-transmitting region 201. When the electronic apparatus 100 is in a folded state (as shown in fig. 4), the first through hole 21 on the second body 20 is located to face the first photographing device 50.

In other words, the second body 20 is provided with the first through hole 21 penetrating the front and back surfaces of the second body 20 at a position facing the first photographing device 50 in the folded state.

The folded state is a state in which the first body 10 and the second body 20 are stacked together. When the electronic device 100 is in the folded state, an included angle between the first body 10 and the second body 20 is 0 degree. The unfolded state is a state in which the first body 10 and the second body 20 are not overlapped, i.e., a state other than the folded state, for example, a state in which the first body 10 and the second body 20 are unfolded and located on the same plane, i.e., an included angle between the first body 10 and the second body 20 is 180 degrees.

It is understood that in other embodiments, when the electronic device 100 is in the folded state, the included angle between the first body 10 and the second body 20 is less than or equal to an angle threshold. For example, the angle threshold may be 10 °. The folded state and the unfolded state referred to in the present invention are relative concepts, that is, as long as the degree of unfolding of one state is greater than that of the other state, the former is considered to be the unfolded state and the latter is considered to be the folded state.

In this embodiment, the controller 60 can control the first photographing device 50 to extend into the first through hole 21 when the electronic device 100 is in the folded state and there is a photographing requirement, so that the first photographing device 50 can photograph the front-facing scenery of the second body 20 through the first through hole 21. The determination that there is a shooting demand is that the controller 60 acquires a shooting mode start instruction. The display screen 30 is a touch display screen, and the shooting mode starting instruction may be an instruction for a user to start the first shooting device 50 and select a shooting mode through a touch operation on the display screen 30. It is understood that the shooting mode initiation instruction may also be generated by other means, such as by the user pressing a key on the electronic device 100, etc. It is understood that the controller 60 can control the first camera 50 to extend into the first through hole 21 when the electronic apparatus 100 is in the folded state but there is no shooting requirement.

According to the electronic device 100 provided by the embodiment, when the electronic device 100 is in the folded state and it is determined that there is a shooting requirement, the controller 60 controls the first shooting device 50 to extend into the first through hole 21, and the first shooting device 50 can be used as a front camera to realize a self-shooting function, so that the use convenience of the electronic device 100 is improved, and the use of a user is facilitated. When the electronic apparatus 100 is in the unfolded state, the first photographing device 50 may be used as a rear camera.

In an embodiment, the electronic device 100 further includes a connector 70, and the first body 10 and the second body 20 are rotatably connected through the connector 70. It is understood that the connecting member 70 may be a rotating shaft, a hinge structure, leather, bendable metal, etc. The display screen 30 can be bent following the rotation of the first body 10 relative to the second body 20. It is understood that the connector 70 may be omitted.

In one embodiment, the aperture of the first through hole 21 is gradually increased in a direction in which the front surface of the second body 20 faces the back surface of the second body 20, for facilitating the first photographing device 50 to be inserted and withdrawn. In the present embodiment, the first body 10, the second body 20 and the display 30 form an accommodating space 101 together. An opening 13 communicating with the receiving space 101 is opened on the rear surface of the first body 10.

The driving member 41 can drive the first photographing device 50 to extend or retract into the first body 10 through the transmission member 43.

In this embodiment, the driving mechanism 40 further includes a bracket 45, the driving element 41 is a rotating motor, the rotating shaft 411 of the driving element 41 can rotatably penetrate through the bracket 45, and the bracket 45 is used for enhancing the motion stability of the first photographing device 50. The transmission member 43 is connected to the rotating shaft 411 of the driving member 41, and the transmission member 43 is engaged with the rotating shaft 411 of the driving member 41. When the rotating shaft 411 of the driving member 41 rotates in a first direction (e.g., clockwise), the driving member 43 is extended and pushes the first camera 50 to move in the first direction, such that the first camera 50 extends out of the opening 13, and the first camera 50 enters the first through hole 21 when the electronic device 100 is in the folded state. When the rotating shaft 411 of the driving component 41 rotates along a second direction (e.g., counterclockwise), the driving component 43 pulls the first camera 50 to move towards the second direction, so that the first camera 50 retracts to exit the first through hole 21. In addition, the transmission member 43 includes a plurality of racks 431, and the rotating shaft 411 of the driving member 41 and the transmission member 43 are engaged with each other through the racks 431, so that the transmission member 43 can be firmly engaged with the rotating shaft 411 of the driving member 41, thereby avoiding affecting the shooting performance of the first shooting device 50.

It should be understood that the driving element 41 is not limited to be a rotating motor, the driving element 41 may be other driving structures, such as a linear motor, an air cylinder, etc., the driving element 41 may be capable of driving the first photographing device 50 to perform a telescopic motion, and the transmission element 43 may be omitted.

A second through hole 35 (as shown in fig. 1) corresponding to the first through hole 21 is formed in the second display screen 33, and the first through hole 21 and the second through hole 35 are communicated to form a channel. Light can enter the passage from the second through hole 35, that is, the first photographing device 50 can photograph toward the second display screen 33 side. As shown in fig. 6, the electronic apparatus 100 further includes a first optical module 70, the first optical module 70 is located in the passageway, and when the first camera 50 extends into the first through hole 21, the first optical module 70 is located in front of the optical path of the first camera 50, that is, located at an outer side of the first optical module 70, which is closer to the second display screen 33 than the first camera 50, and the first optical module 70 and the first camera 50 form a second camera. In this embodiment, the first optical module 70 is disposed at one end of the first through hole 21 adjacent to the second through hole 35, and the first optical module 70 includes at least one lens. In other embodiments, the first optical module 70 includes a plurality of lenses and is fixedly disposed in the first through hole 21.

In some embodiments, the second display screen 33 may not be provided with the second through hole 35, and the first through hole 21 may not be provided in the transparent region 201. The second display screen 33 is made of a transparent material, and when the controller 60 controls the first photographing device 50 to photograph, the controller also controls the display screen 30 not to display and present a transparent effect corresponding to a preset area of the first photographing device 50, so that light can pass through the preset area, and the first photographing device 50 can photograph. In another embodiment, the first through hole 21 is formed in the light-transmitting area 201, so that light can enter the first through hole 21 through the predetermined area, and the first photographing device 50 can photograph. In other words, when the electronic apparatus 100 is in the folded state, the preset region corresponding to the first photographing device 50 on the second display screen 33 is controlled not to be displayed. The light-transmitting area 201 is located in the preset area, and the projection area of the preset area on the same plane is larger than or equal to the projection area of the light-transmitting area on the same plane.

According to the field angle FOV is 2 × artan (Φ × y/2), where y is the height of the sensing area of the image sensor of the first camera 50. Since the height y of the sensing area of the image sensor of the first photographing device 50 is a fixed size, the entire field angle FOV can be changed by changing the combined power Φ. In this embodiment, the focal length of the first camera 50 is 4mm, the relative aperture of the first camera 50, i.e. the F-number (F-number) of the first camera 50 is 2.2, the focal length of the first optical module 70 is-8.5 mm, and the first optical module 70 is located in the first through hole 31.
