The mobile phone is the electronic equipment provided with the cellular communication module.

It should be noted that, the electronic device in the embodiment of the present application is mainly directed to an electronic device having a folding screen, for example, a folding screen mobile phone. The folding screen mobile phone has gradually become the development trend of the whole machine in the future, and has the advantages of entertainment and office, portability and capability of meeting the current requirements of consumers for portability and various and unified functions. The folding screen mobile phone generally has folding modes such as inward folding, outward folding and the like. For the folding screen mobile phone in the inward folding mode, after the folding is completed, the display surfaces of the flexible screen are close to each other along the folding area, namely the flexible screen is in the inward folding mode. For the folding screen mobile phone in the outward folding mode, after the folding is completed, the display surfaces of the flexible screen deviate from each other along the folding area, namely the flexible screen is in a folding mode of being folded outwards.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an electronic device 100 according to some embodiments of the application. The electronic device 100 may include a folding housing 110 and a flexible member 120 provided on the folding housing 110, the folding housing 110 supporting the flexible member 120. The flexible member 120 may be, but is not limited to, flexible display screen, flexible touch display screen, and other flexible components with corresponding functions. The flexible member 120 covers the front surface of the folding housing 110, and the flexible member 120 is folded or flattened along with the folding housing 110.

The flexible member 120 has a folding region 121 and an unfolding region 122, and the folding region 121 is connected to the folding region 122. Alternatively, the folded region 121 is located in a central region of the flexible member 120, and the unfolded region 122 is located on opposite sides of the folded region 121, i.e., the unfolded region 122 may be two. When the electronic device 100 is in the open state, the folded region 121 is flattened to be flat, and the two non-folded regions 122 are located on opposite sides of the folded region 121, so that the flexible member 120 can assume a flat non-folded state. When the electronic device 100 is in the folded state, the folded region 121 may be folded into an arc shape, and the two non-folded regions 122 are located on the same side of the folded region 121 and are close to each other, so that the flexible member 120 may take on a folded state such as a water drop type or a bent type.

Further, the folding housing 110 may include a first housing 111 and a second housing 112 disposed opposite to each other, and a folding device 113 disposed between the first housing 111 and the second housing 112.

The first housing 111 and the second housing 112 may be rotatably connected by means of the folding device 113, i.e. opposite ends of the folding device 113 may be connected to the first housing 111 and the second housing 112, respectively. When the electronic apparatus 100 is changed from the open state to the folded state, the first housing 111 and the second housing 112 move toward each other to fold the folded housing 110; when the electronic apparatus 100 is changed from the folded state to the unfolded state, the first housing 111 and the second housing 112 are moved back to each other so that the folded housing 110 is unfolded.

Wherein the structures of the first housing 111 and the second housing 112 may be the same or different.

Further, the flexible member 120 may be synchronously unfolded or folded as the folding housing 110 is unfolded or folded. Alternatively, opposite ends of the folding device 113 are fixedly connected to the first and second housings 111 and 112, respectively, so that the folding device 113 can be folded in synchronization with the folding housing 110, i.e., a substantially uniform folding angle can be maintained.

The folding device 113 is disposed on the back of the flexible element 120 and corresponds to the folding region 121 of the flexible element 120. The first and second cases 111 and 112 are disposed on the back of the flexible member 120 and correspond to the non-folded regions 122 of the flexible member 120, respectively. In other words, the folding device 113 is used to support the folding area 121 of the flexible member 120, and the folding area 121 is synchronously folded as the folding device 113 is folded, or is synchronously flattened as the folding device 113 is flattened. Specifically, during the folding process of the first casing 111 and the second casing 112, the folding device 113 is driven to rotate, so that the folding device 113 can enclose a Rong Bing space, the folding region 121 is folded along with the folding device 113, and the folded region 121 is accommodated in the Rong Bing space after being folded. The first casing 111 and the second casing 112 drive the folding device 113 to rotate to flatten during flattening, and the folding area 121 flattens along with the folding device 113. The front side in the present application refers to the side facing the flexible member 120, and the back side refers to the side facing away from the flexible member 120.

Referring to fig. 2 to 4, fig. 2 is a schematic structural diagram of a folding device 113 according to some embodiments of the present application, fig. 3 is a schematic structural exploded view of the folding device 113 according to the embodiment of fig. 2, and fig. 4 is an enlarged schematic partial structural diagram of a region a of the folding device 113 according to the embodiment of fig. 3.

Folding device 113 may include a base 310, a connection assembly 320 rotatably coupled to base 310, and a support assembly 330 movably coupled to connection assembly 320. In other words, one end of the connection assembly 320 is rotatably connected to the base 310, and the other end is movably connected to the support assembly 330, so that the support assembly 330 can move relative to the base 310.

The base 310 is located between the first housing 111 and the second housing 112 and corresponds to the folded region 121 of the flexible member 120.

In an embodiment, the connecting members 320 may have two, two connecting members 320 are rotatably connected to opposite sides of the base 310, and each connecting member 320 is movably connected with the supporting member 330, i.e. the supporting member 330 may have two. The relative movement between the first housing 111 and the second housing 112 may drive the support assembly 330 to rotate relative to the base 310, so that the support assembly 330 is flattened or folded, so as to achieve bending or flattening of the flexible member 120. Optionally, the first housing 111 and the second housing 112 are folded by relatively approaching rotation to drive the two support assemblies 330 to rotate to approach each other, so that the folding device 113 is folded to bend the flexible member 120. Alternatively, the first housing 111 and the second housing 112 are relatively rotated away from each other to be flattened, so as to drive the two support assemblies 330 to rotate away from each other, so that the folding device 113 is flattened to achieve flattening of the flexible member 120.

Alternatively, one of the two support members 330 may be connected to the first housing 111 and the other may be connected to the second housing 112 so that the two support members 330 may be relatively moved therebetween when the first housing 111 and the second housing 112 are relatively moved.

Further, when the two support assemblies 330 are folded by rotating relative to the base 310, the two support assemblies 330 can be enclosed with the base 310 to form a screen space, and the screen space is a circular space with a water drop bottom, so that the folded region 121 of the flexible member 120 can be accommodated in the Rong Bing space and is in the form of a water drop when folded.

In an embodiment, the first housing 111 and the second housing 112 may be symmetrically disposed along the base 310. The two connection assemblies 320 may be symmetrically disposed along the base 310. The two support assemblies 330 may be symmetrically disposed along the base 310.

Alternatively, the fold line L may be a midline of the base 310, i.e., the base 310 may be symmetrically configured along the fold line L. Alternatively, the two connection assemblies 320 may be symmetrically disposed along the folding line L. The two support assemblies 330 may be symmetrically disposed along the fold line L.

Referring again to fig. 2 to 4, the base 310 may have a back cover 310a, a first connection portion 311, and a second connection portion 312. The first and second connection parts 311 and 312 may be provided on the back cover 310a at intervals, and integrally formed with the back cover 310 a.

Each of the connection assemblies 320 may include a first connection 321 and a second connection 322 provided on the base 310. Each support assembly 330 may include a support 331 disposed spaced apart from the base 310. It is understood that the folding device 113 may include multiple sets of connection assemblies 320, and that each set of connection assemblies 320 may include two connection assemblies 320 symmetrically disposed along the base 310. The support assembly 330 may include a plurality of sets of supports 331, and each set of supports 331 may include two supports 331 symmetrically disposed along the base 310. Alternatively, one of the two supports 331 may be connected to the first housing 111, and the other may be connected to the second housing 112, so that the two supports 331 may be relatively moved therebetween when the first housing 111 and the second housing 112 are relatively moved.

Wherein the supporting members 331 are disposed in one-to-one correspondence with the connection members 320. In other words, one end of each connecting component 320 is rotatably connected with the base 310, and the other end is movably connected with the corresponding support 331, so that the support 331 can move relative to the base 310. As shown in fig. 3, the folding device 113 may include 3 sets of connection assemblies 320, and the 3 sets of connection assemblies 320 are sequentially arranged along the extending direction of the folding line L.

In other words, the first portion 3311 and the second portion 3312 may be of unitary construction, i.e., the first portion 3311 and the second portion 3312 are integrally formed to form the support 331. Of course, in other embodiments, the first portion 3311 and the second portion 3312 may be separately formed and assembled to form the support 331 described above.

In summary, during the folding process of the electronic device 100, the support 331 may rotate relative to the back cover 310a of the base 310 and may move relative to the back cover 310a, that is, the support 331 may move in a direction approaching or separating from the back cover 310 a. Wherein, a side of the second surface 3102 of the back cover 310a facing away from the first surface 3101 is defined as a first side of the back cover 310a, a side adjacent to the first side is defined as a second side of the back cover 310a, and the support 331 is located on the second side of the back cover 310 a. Wherein the support 331 rotates relative to the base 310 such that the folding device 113 has a first state (i.e., a flattened state) and a second state (i.e., a folded state), the support 331 being located on the second side of the back cover 310a in the first state; in the second state, the support 331 is located on the first side of the back cover 310 a. The support 331 is rotatable relative to the base 310 via the first connecting member 321, and the support 331 and the second connecting member 322 are slidably connected, such that the support 331 is far away from or near the base 310 when the support 331 and the base 310 are rotated relatively.

For example, in the first state, there is a first spacing between the support 331 and the base 310; in the second state, there is a second spacing between the support 331 and the base 310; wherein the first pitch is smaller than the second pitch. Specifically, in the first state, the folding device 113 is in an open state, when a force is applied to the support 331 to rotate the support 331 relative to the base 310, and thus the folding device 113 is switched from the first state to the second state, the support 331 drives the first connecting piece 321 to rotate relative to the base 310, and at the same time, the second connecting piece 322 slides relative to the support 331 under the force of the support 331, and thus the support 331 is gradually far away from the base 310. In the second state, the folding device 113 is in a folded state, when a force is applied to the support 331 to rotate the support 331 relative to the base 310, so that the folding device 113 is switched from the second state to the first state, the support 331 drives the first connecting piece 321 to rotate relative to the base 310, and at the same time, the second connecting piece 322 slides relative to the support 331 under the force of the support 331, so that the support 331 gradually approaches the base 310.

Further, through setting up second connecting piece and support piece sliding connection for can produce relative slip between second connecting piece and the support piece, and then make support piece can realize when rotating for the base that support piece is kept away from or is close to the base, overall structure is simple.

Referring again to fig. 8, the folding device 113 may further include an elastic member 303, where the elastic member 303 may be a spring sleeved on an end of the second rotating shaft 302 away from the second connecting member 322.
