The folding device 20 may be a hinge, and the folding device 20 may include two rotating mechanisms, and the two rotating mechanisms are in a rotating fit, so that the folding device 20 can be folded or unfolded relatively. The two shells can be respectively connected with two rotating mechanisms of the folding device 20, so that the two shells can realize rotating fit through the folding device 20, and the two shells can rotate relatively, namely, the first shell 11 and the second shell 12 can rotate relatively, so that the folding and flattening of the electronic equipment 100 are realized.

The folding device 20 may be connected to the first housing 11 and the second housing 12 by various manners, for example, bonding, welding, clamping, fastening by screws, or the like.

Referring to fig. 1, the first housing 11 and the second housing 12 can be relatively folded to a closed state, and illustratively, the first housing 11 and the second housing 12 are in a closed state, and can be completely folded to be parallel to each other, at this time, the electronic device 100 is in a closed state, which is also called a folded state, and the electronic device 100 is folded to be in a two-layer form.

Referring to fig. 2, the first housing 11 and the second housing 12 can be relatively unfolded to an open state, and, for example, when the first housing 11 and the second housing 12 are in the open state, they may be substantially 180 °, and the electronic device 100 is in the open state, which is also referred to as a flattened state.

The electronic device 100 may also have an intermediate state, which may be any state between an open state and a closed state. That is, the electronic device 100 may be switched between an open state (i.e., a flattened state) and a closed state (i.e., a folded state) by movement of the folding apparatus 20.

The common foldable electronic equipment further comprises a flexible display screen, wherein the flexible display screen is used for realizing the display of images, the flexible display screen is also used for identifying control information and the like of a user so as to realize man-machine interaction with the user, and the flexible display screen is formed by laminating special coating layers with display functions, electric signal processing functions, touch control functions and the like, so that the display of the images is realized in an internal luminous mode. The flexible display screen is generally laid on the folding device and the housing, and when the electronic device is in a folded state, the flexible display screen is located between the two housings, and a part of the flexible display screen opposite to the folding device is bent and located in a Rong Bing space enclosed by the folding device. When the shell is relatively opened, the flexible display screen is opened along with the shell, and when the electronic equipment is in a flattened state, the flexible display screen is tiled on the shell and the folding device, so that large-screen display is realized.

In the continuous opening and closing process, layering is easy to occur due to the fact that the flexible display screen is complex in lamination. In the scenes such as collision and collision, the flexible display screen is easy to damage, and poor display reliability is caused by the problems of black spots, broken bright spots and the like. And the cost of the flexible display screen is high, and the replacement and maintenance cost is high. In addition, in order to protect the flexible display screen, when the electronic equipment is in a folded state, the bending angle of the flexible display screen is also larger, so that the thickness of the electronic equipment is larger, and the thinning design of the electronic equipment is not facilitated.

Based on the above, the foldable electronic device with the flexible screen provided by the embodiment of the application uses the flexible screen and the projection device to realize the function of the flexible display screen, the flexible screen is not easy to damage in the bending and opening process, the falling and impacting process and the like, has stronger bending durability, long service life and better reliability, has lower manufacturing and maintenance cost of the flexible screen, and is beneficial to thinning of the electronic device.

Taking the foldable electronic device 100 as an example, referring to fig. 2, the foldable electronic device 100 further includes a flexible screen 30, where the flexible screen 30 is a structural component that does not emit light, and has a characteristic of reflecting light, and is used as a display carrier or an imaging medium for displaying images, for example, the flexible screen may be a white screen. The flexible screen 30 is laid on the first housing 11, the second housing 12, and the folder 20, and the flexible screen 30 may be disposed on the same side surface of the first housing 11, the second housing 12, and the folder 20.

Wherein the flexible screen 30 may be attached to the first housing 11 and the second housing 12, respectively. Specifically, the flexible screen 30 may be attached to the first housing 11 and the second housing 12 by way of adhesion, however, in some other examples, the flexible screen 30 may be attached to the first housing 11 and the second housing 12 by way of fasteners or the like.

When the first housing 11 and the second housing 12 are rotated and folded relatively, the flexible screen 30 is attached to the first housing 11 and the second housing 12 and rotates therewith, and a portion of the flexible screen 30 opposite to the folding device 20 is folded. When the electronic apparatus 100 is in the folded state, a portion of the flexible screen 30 opposite to the folding device 20 is accommodated in the Rong Bing space 21 (see fig. 11) enclosed by the folding device 20, and the electronic apparatus 100 has a small size and is easy to carry.

When the first housing 11 and the second housing 12 are relatively unfolded, the folding device 20 and the flexible screen 30 are also unfolded. Referring to fig. 2, when the electronic apparatus 100 is in a flattened state, the flexible screen 30 is tiled on the same side surfaces of the first housing 11, the second housing 12, and the folding device 20.

In the case of the foldable electronic device 100 of the inward folding type, the flexible screen 30 is disposed on the inner side surfaces of the first housing 11, the second housing 12, and the folding apparatus 20. For the foldable electronic device 100 of the out-folding type, the flexible screen 30 is provided on the outer side surfaces of the first housing 11, the second housing 12, and the folding means 20.

When the electronic device 100 is in the folded state, two surfaces of the first housing 11 and the second housing 12 that are adjacent and opposite to each other are inner side surfaces of the first housing 11 and the second housing 12, respectively, and a surface of the folding device 20 on the same side as the inner side surfaces of the first housing 11 and the second housing 12 is an inner side surface of the folding device 20. The two opposite surfaces of the first housing 11 and the second housing 12 are the outer side surfaces of the first housing 11 and the second housing 12, respectively, and the surface on the same side of the folding device 20 as the outer side surfaces of the first housing 11 and the second housing 12 is the outer side surface of the folding device 20.

In order to realize the display function of the electronic device 100, as shown in fig. 2, the electronic device 100 may further include a projection device 40, where the projection device 40 may be disposed on one of the housings, for example, may be disposed on the first housing 11, and the projection device 40 may be capable of forming a display image. When the electronic device 100 is in the flattened state, the projection device 40 can project the formed display image onto the tiled flexible screen 30, so as to realize the display of the image, that is, the large screen display after the electronic device 100 is unfolded.

The flexible screen 30 is only used as a display carrier or an imaging medium for displaying images, does not emit light, has no requirements for display functions, touch functions and the like, has a simple laminated structure, does not need to be added with a coating with display functions, electric signal processing functions, touch functions and the like, has high reliability, is not easy to damage in the bending and unfolding processes along with the electronic equipment 100, can reduce or avoid the problem of poor display such as black spots, broken bright spots and the like, and obviously improves the reliability of the electronic equipment 100 on the premise of ensuring the display functions of the electronic equipment 100. And the flexible screen 30 has lower cost, which is beneficial to reducing the production cost and the replacement maintenance cost of the electronic device 100.

In addition, when the electronic device 100 is in a folded state, the bending angle requirement of the flexible screen 30 is relatively smaller, and under the condition that the flexible screen 30 is not damaged, the flexible screen 30 can be bent to a smaller bending angle, that is, the bending at a smaller angle is realized, which is favorable for reducing the thickness of the electronic device 100 and realizing the thinning design of the electronic device 100.

The flexible screen 30 may be a structural member with better softness and better directional light reflection characteristics, for example, the molding material of the flexible screen 30 may include soft resin or glass plastic material, and the flexible screen 30 may be, for example, white plastic cloth, glass fiber board, polyvinyl chloride (Polyvinyl chloride, abbreviated as PVC) board, etc.

The flexible screen 30 may be formed of one material layer, or the flexible screen 30 may be a laminated structure formed of a stack of multiple material layers.

It should be noted that, the information interaction function may be realized by the projection device 40, that is, the projection device 40 may not only realize the display function of the image, but also realize the functions of detecting and acquiring the user operation information, and so on, so as to realize the man-machine interaction. For example, a manipulation function sensor (see fig. 9) capable of detecting and acquiring operation information of a user may be provided in the projection device 40.

For example, the manipulation function sensor 42 may be an infrared sensor, and the manipulation function sensor 42 may detect and acquire operation information of the user by means of infrared positioning, for example, by positioning a position or gesture track of the user's operation in x, y, z three-dimensional directions by emitted infrared light, so as to detect whether the user makes the operation. And when the user makes an operation, operation information such as the position and track forming the operation is acquired. The control function sensor 42 can be connected with a main control board of the electronic equipment, and the control function sensor 42 can transmit operation information obtained through detection to the electronic equipment, so that the electronic equipment can react according to the operation information, the information interaction function of the electronic equipment and a user is realized, and the performance of the electronic equipment is further improved.

Of course, in some other examples, the manipulation function sensor 42 may be other sensors capable of implementing the light positioning recognition function, for example, the manipulation function sensor 42 may also be a laser sensor.

Or the information interaction function may be implemented by other structures, for example, a display screen disposed on a side opposite to the flexible screen on the housing, which will be described later, that is, the projection device 40 may only implement a projection display function, where the display screen is used to detect and acquire operation information of the user.

It should be appreciated that in some other examples, the foldable electronic device may also be a notebook computer, which may include a first housing and a second housing that are relatively foldable to a closed state, such that the notebook computer is in a closed state (i.e., a folded state). Accordingly, the first and second housings are relatively unfolded from the folded state to the unfolded state, the notebook computer is in the unfolded state (i.e., the flattened state), and the projection device may be disposed on at least one of the first and second housings.
