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 devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the description of the present disclosure, it should be understood that the terms "center", "upper", "lower", "top", "horizontal", "bottom", "inner", "outer", and the like indicate an orientation or a positional relationship based on a user's use of the terminal, and do not limit the present disclosure.

As shown in fig. 4 to 12, an embodiment of the present disclosure provides a terminal, including:

a folding screen assembly;

the shell 110 comprises a first shell 114 and a second shell 115, wherein the first shell 114 is connected with the second shell 115 through a bending area, and the first shell 114 and the second shell 115 are used for bearing the folding screen assembly;

the bending region includes:

the first sealing body 120 is located at a side of the bending region, and forms a first sealing surface for sealing a gap between the foldable screen assembly and the housing 110.

In the embodiment of the disclosure, the first sealing body is positioned on the side face of the bending region, so that external dust, liquid and light are prevented from entering the terminal through a gap between the folding screen assembly and the shell, and the sealing performance of the bending region is improved. And moreover, the first sealing body is used for filling the holes generated during deformation of the bending area, so that the first sealing body is adaptive to deformation of the bending area, and the conversion function of the terminal between bending and flattening is ensured.

Without limitation, the deformation of the first sealing body may depend only on the characteristics of the material of the first sealing body, for example, the first sealing body is made of plastic material, and the deformation of the bending region can be absorbed by the elastic deformation of the plastic material. Alternatively, the deformation of the first sealing body may be dependent on its own structural properties, e.g. the sealing body has a bent portion, the deformation of the bent area being absorbed by the compression and extension of the bent portion.

As shown in fig. 4 to 6, the first sealing body 120 is deformed as the flexible folding screen assembly is bent; as shown in fig. 9, 10 and 11, in the unfolded state, the first sealing body 120 also recovers its shape as the flexible folding screen assembly is unfolded.

The bending region includes a joining region of the first housing 114 and the second housing 115, and the joining region may be a broken portion between the first housing 114 and the second housing 115 in fig. 4, 5, and 11. The first housing 114 and the second housing 115 can rotate relative to each other through the folded region, and drive the folding screen assembly to switch between folding and unfolding.

The rotation between the first housing 114 and the second housing 115 may be such that the folding screen assembly is folded inwards or outwards, the inwards folding refers to the bending process in which the folding screen assembly is gradually hidden, and when the inwards folding is at its maximum, the folding screen assembly may be completely hidden inside and the housing is exposed outside. Accordingly, when the first and second housings 114 and 115 are folded outward, the rotation directions of the first and second housings 114 and 115 are opposite to each other, the folding outward is a bending process in which the folding screen assembly is gradually exposed, and when the folding outward is maximized, the first and second housings 114 and 115 may be almost completely hidden inside, and the folding screen assembly is exposed outside.

In some specific examples, the bending region may further include a rotating shaft connecting the first housing 114 and the second housing 115, and the first housing 114 may rotate relative to the second housing 115 through the rotating shaft. The rotating shaft is not limited to the shaft-type rotating connecting part, but includes a non-shaft-type rotating connecting part, for example: the rotating shaft can also be a gear type rotating connecting part, or a rotating connecting part formed by folding sheets, and the like.

The terminal includes, but is not limited to, an electronic device with a display screen, such as a mobile phone, a tablet computer, a notebook computer, a display, an electronic reader, a television, a wearable device, or a vehicle-mounted computer.

In other alternative embodiments, the first sealing body comprises:

a connecting part connected with the housing;

first pars contractilis links to each other with connecting portion and folding screen subassembly, and first pars contractilis can stretch out and draw back according to the state of buckling of folding screen subassembly.

In the embodiment of the present disclosure, the connecting portion is used to fix the first sealing body, and the first expansion portion is used to absorb deformation of the bending region, at this time, the first sealing body absorbs deformation of the bending region by virtue of its own structural characteristics. In the case of the terminal not being folded (i.e. in the case of the terminal being unfolded), the first telescopic part is in the contracted state, and in the case of the electronic device being folded, the first telescopic part is in the extended state, so as to fill the space into which the device is folded, thereby further performing the sealing function.

Without limitation, as shown in fig. 11 and 12, the side surface of the first sealing body in the first direction is in contact with the housing, the side surface of the first sealing body in the second direction is bonded to the housing with an adhesive, and the bottom portion of the first sealing body is bonded to the housing with an adhesive. Two sides of the first sealing body 120 along the first direction are not fixed with the housing 110, so that the limitation of the first expansion part 121 on the deformation process by the housing 110 is reduced, and the deformation function of the first expansion part 121 is ensured. As shown in fig. 11, the connecting portion 122 is fixed to the housing 110 by adhesion, which enhances the connection between the housing 110 and the first sealing body 120. The first direction is parallel to the central line of the bending region, when the terminal comprises a rotating shaft, the first direction is also the axial direction of the rotating shaft, and the second direction is perpendicular to the first direction.

In other alternative embodiments, the first telescoping portion comprises one or more connected folded sheets; when the folding screen assembly is unfolded and bent, the folding form and/or the folding degree of the first telescopic part are different.

The folding piece is in a folded state when the terminal is unfolded; when the terminal is folded, the folding degree of the folding sheet in one partial area of the first telescopic part can be relieved, even unfolded, so as to fill the space introduced by the equipment in a folding way, and further play a sealing role.

When the folding sheet 1211 has a plurality of sheets, as shown in fig. 4, 11 and 12, the plurality of folding sheets 1211 may be connected end to end in sequence to form a stretching and folding mechanism like a folding fan or an accordion. When the foldable sheet 1211 is bent, the foldable sheet 1211 is compressed by a force, the folding degree of the foldable sheet 1211 is increased, and when the foldable sheet 1211 is bent to the maximum degree, the folding shape of the first telescopic part 121 can be in a U shape or a drop shape; when the foldable sheet 1211 is unfolded, the foldable degree of the foldable sheet 1211 is reduced, or the foldable sheet 1211 is restored to an original state without stress, and when the foldable sheet 1211 is unfolded to the maximum degree, the foldable shape of the first expansion part 121 can be horizontal.

The folded sheet may be formed by bending a sheet material, the bent portion of the folded sheet forming a groove. Because the deformation process of the folding sheet is the process of extruding the gas in the groove when the folding sheet is bent, the process that different parts of the folding sheet are close to each other is also the process that the hardness of the first telescopic part is increased. Compare the elastic deformation who utilizes self material, the first pars contractilis of this kind of structure is still less even after compression deformation, can reduce the extrusion of first seal to folding screen subassembly, can adapt to the deformation of folding screen subassembly better.

Without limitation, the cross-section of the single folded sheet may be V-shaped, U-shaped, or arched, etc.

The connecting portion may be circumferentially surrounded outside the first stretchable portion. As shown in fig. 4 to 11, taking the first sealing body 120 having a rectangular cross section as an example, the connection portion 122 may be connected outside the two short sides 1222 and the bottom-side one long side 1221 of the first sealing body 120.

In other optional embodiments, the connecting portion has a second expansion portion on a side of the bending region opposite to the first expansion portion, and the top end of the second expansion portion is provided with a plurality of openings;

when the folding screen assembly is unfolded from the closing process, the distance between the adjacent openings is gradually reduced from the maximum value to 0.

In the disclosed embodiment, when the folding screen assembly is unfolded and bent, the distance between adjacent openings is different. And the distance between adjacent openings can be reduced in a non-linear way or according to the reduction corresponding to the angle change when the folding screen component is in the process from closing to unfolding. The second pars contractilis located the one side of connecting portion dorsad first pars contractilis, and the second pars contractilis realizes flexible through a plurality of openings. The spacing between adjacent openings of the folding screen assembly in the unfolded state is smaller than the spacing between adjacent openings of the folding screen assembly in the folded state. Specifically, when folding screen assembly buckles, the interval increases between a plurality of openings of second pars contractilis, and wherein, the distance that is located between the opening of different positions can be different, for example, is located the regional great central point that warp of buckling and puts, and the distance is great between the adjacent opening, and is located the regional less marginal position that warp of buckling, and the distance is less between the adjacent opening, and at this moment, the second pars contractilis in the state of stretching. In contrast, when the folding screen assembly is unfolded, the distance between the plurality of openings is reduced, even, the adjacent openings can be tightly attached, and at the moment, the second telescopic part is in a contracted state. The deformation effect of the folding screen assembly can be better absorbed by the change of the distance between the adjacent sawteeth, and the hardness of the first sealing body is further reduced when the folding screen assembly is bent.

In a specific example, when the bending region includes the rotating shaft, as shown in fig. 4 and 5, and fig. 7 to 11, the top of the first expansion part 121 is not connected with the connecting part 122, and the bottom of the first expansion part 121 opposite to the rotating shaft is connected with the connecting part 122, wherein a portion of the connecting part 122 opposite to the rotating shaft has a plurality of openings 123, and the portion of the connecting part 122 opposite to the rotating shaft is not fixedly connected with the rotating shaft, and the two can be separated from each other to reduce the influence on the process of switching the bending state and the flattening state. Without limitation, the openings are tooth-shaped. For example, the openings include, but are not limited to, triangular teeth, rectangular teeth, or trapezoidal teeth.

In other alternative embodiments, the bending region further comprises:

and the second sealing body is positioned between the first shell and the second shell and used for sealing gaps among the openings in different states.

In practical application, folding screen is at the in-process of buckling, can have the not clearance of equidimension when different states of buckling between the adjacent opening, and the second seal can seal the clearance between the adjacent opening, further improves the sealed effect to the terminal.

Without limitation, the second encapsulant is part of the housing, for example, as shown in fig. 6, the edges of the housing are multiplexed into a second encapsulant 180. Or, the second sealing body is a structure which is provided by the shell and is matched with the opening, wherein the matched structure can be a tooth-shaped structure and the like. The shell is wrapped on the outer side of the second sealing body, and sealing of direct gaps of adjacent openings can be achieved.

In other alternative embodiments, the first sealing body comprises: and the flexible film is connected with the shell and the folding screen assembly in the bending area to form a sealing surface.

Except adopting above-mentioned first sealing body that has connecting portion and first pars contractilis structure, first sealing body can also be one deck or multilayer flexible membrane, and the flexible membrane accessible forms sealed face with being connected of sealed casing and folding screen subassembly to utilize flexible membrane's scalability, the sealed folding screen subassembly under different states such as fold condition and expansion state and the gap between the casing, guarantee the sealed effect at terminal.

In other alternative embodiments, the plurality of flexible membranes define a cavity therebetween, the cavity being filled with a stretchable material.

In some specific examples, the stretchable material may be a gas, such as: air, etc. In other embodiments, the flexible membrane may be directly made of an elastic member with a high elastic ratio, for example, the elastic member is a plastic material such as silicon rubber.

Specifically, at the edge 111 of the housing 110, the top of the housing 110 includes a protruding portion 113 protruding toward the center of the housing 110, the protruding portion 113 covers the top of the sealing body 120, and the abutting surface 1131 of the protruding portion 113 opposite to the first sealing body 120 has a limiting effect on the first sealing body 120. The sealing body 120 is prevented from being protruded upwards after being bent to be flattened, and the thrust of the first sealing body 120 to the folding screen assembly can be reduced to enable the folding screen assembly to be protruded out of the shell 110 after being flattened, so that the folding screen assembly is uneven in the unfolding state.

In addition, the top of the shell has a shielding effect and a protection effect on the first sealing body.

Further, as shown in fig. 12, the bottom of the first sealing body 120 is at least partially opposite to the bottom of the housing 110. In practical applications, the housing 110 encloses a cavity, which, in addition to accommodating the folding screen 150, can also provide space for the first sealing body 120. At this moment, the opposite butt joint surface 112 in bottom of casing 110 and first seal 120 also has limiting displacement to the first seal, and this limiting displacement has ascending thrust to first seal 120, mutually supports with above-mentioned limiting displacement of limit structure, can further guarantee to buckle to the flattening transition after, the planarization of folding screen subassembly.
