In the present application, the display screen may be a foldable flexible screen, for example, a foldable OLED screen; the display screen may also be a non-flexible screen that is not foldable, such as a liquid crystal screen, a non-flexible OLED screen, etc.

Referring to fig. 1 and 2, in the present embodiment, the display screen is a flexible screen, and the protection device 100 includes a main body 1 for covering the flexible screen, a side wall 5 connected to the main body, and a buffer portion 3 and a holding portion 4 respectively located at two sides of the main body 1. The buffer portion 3 and the side wall 5 extend in the thickness direction of the main body 1, the buffer portion 3 extends in the direction opposite to the direction in which the side wall 5 extends, and the side wall 5 connects the holding portion 4 and the main body 1. The body 1, the side wall 5 and the holding portion 4 enclose an accommodating cavity 10 for accommodating a flexible screen (or a terminal main body), the buffer portion 3 and the accommodating cavity 10 are respectively located at two sides of the body 1 in the thickness direction, that is, the buffer portion 3 protrudes out of the body 1 in the thickness direction, and the holding portion 4 and the buffer portion 3 are also respectively located at two sides of the body 1 in the thickness direction.

Body 1 includes first protection portion 11, second protection portion 12 and connects the third protection portion 13 of first protection portion 11 and second protection portion 12, first protection portion 11 and second protection portion 12 are made by transparent material, third protection portion 13 is made by flexible transparent material. With reference to fig. 1, when the terminal body is in the unfolded state, the flexible screen is entirely coplanar, and the first protection part 11, the second protection part 12 and the third protection part 13 are coplanar and respectively protect each area of the flexible screen; referring to fig. 4, when the terminal body is in a folded state, the first protective portion 11 and the second protective portion 12 are used for protecting a region where the flexible screen is not deformed, and the third protective portion 13 is used for protecting the deformed region; with reference to fig. 2 and 4, when the terminal body is unfolded and folded, the third prevention part 13 can be attached to the deformed region and can always protect the deformed region. No matter what state the terminal main body is in, the body 1 can effectively protect the whole flexible screen; in addition, because first protection portion 11, second protection portion 12 and third protection portion 13 are made by transparent material, after installation protection device 100, the user need not to dismantle protection device and can look over, use terminal body, has brought the facility in the operation, also avoids dismantling protection device after, terminal body suffers the impact and causes the flexible screen to damage.

In this embodiment, the first protection portion 11, the second protection portion 12 and the third protection portion 13 are integrally formed, and the three are made of the same flexible transparent material, which is beneficial to simplifying the production process, thereby improving the production efficiency, and the durability of the integrally formed structure is better than that of the integrally assembled structure. The flexible transparent material is, for example, a transparent resin, and specifically may be a Polypropylene (PP) resin, or may be a mixture of several resins. In order to ensure that the flexible screen has good operation sensitivity and viewing effect, the thicknesses of the first protection part 11, the second protection part 12 and the third protection part 13 are less than 0.7 mm, and the light transmittance is greater than 98%. Of course, the thickness and light transmittance can be adjusted according to the requirements for the protective performance and the requirements for the operation sensitivity and viewing effect. It should be noted that for a high brightness, high sensitivity flexible screen, the thickness and light transmittance requirements may also be reduced appropriately.

In another embodiment, the first and

second protection parts

11 and 12 may also be made of a transparent hard material, such as PC (Polycarbonate), PET (polyethylene terephthalate), and the like. The hard first protector 11 and the hard second protector 12 may be molded first, then fixed in a mold, and the third protector 13, the cushion portion 3, the holding portion 4, and the side wall 5 may be formed by injection molding. Compared with a flexible material, the hard material can enable the protection device to have certain rigidity so as to be better attached to the display surface of the flexible screen (namely the front surface of the flexible screen), particularly when the flexible screen is in a folded state; in addition, hard material has higher mechanical strength and hardness, can absorb the sharp object to the direct impact of the display surface of flexible screen, avoids the flexible screen because of receiving direct impact and damaging.

In other embodiments, the protection device may also only include a body, and the body may be adhered to the flexible screen by transparent glue. Glue is attached to the first protection portion and the second protection portion, and glue is not arranged between the third protection portion and the flexible screen, so that the third protection portion 13 is allowed to be bent and deformed in the process of the flexible screen terminal.

The side walls 5 are used for protecting the side edges of the terminal body, and the holding portion 4 is perpendicular to the side walls 5 and is used for pressing against the back surface (the surface on the side opposite to the flexible screen) of the terminal body so as to fix the protection device to the flexible screen. The protective device 100 comprises a plurality of holding portions 4 for securing the holding device to the flexible screen. The retaining part 4 is connected with the first protection part 11 or the second protection part 12, and is not connected with the third protection part 13, so that the bending stress borne by the third protection part 13 during folding is reduced, the third protection part 13 is easy to deform and can be attached to a deformation part of the flexible screen, and the flexible screen is not easy to tilt. Of course, one holding part 4 may be connected to the first protective part 11 or the second protective part 12 at the same time. The holding portion 4 can be used to alleviate the impact received by the rear surface of the terminal body. In this embodiment, the side wall 5, the holding portion 4, and the main body 1 are integrally formed, thereby further simplifying the production process of the protection device.

The buffer part 3 protrudes from the body 1 in the thickness direction of the flexible screen, and protrudes from the main body 1 and the side wall 5 in the circumferential direction, taking the flexible screen to be placed horizontally as an example, the "circumferential direction" includes any horizontal direction, that is, the buffer part 3 protrudes from the main body 1 and the side wall 5 no matter in the length direction, the width direction, or the direction forming any angle with the length direction or the width direction in the horizontal plane, so that the horizontal projection of the main body and the side wall is located in the horizontal projection of the buffer part 3. When the front face of the terminal body is impacted, the impact object is firstly contacted with the buffer part 3, the buffer part 3 can absorb most of the impulse, and the main body 1 can further absorb the rest of the impulse, so that the front face of the flexible screen is effectively protected. When the side of the terminal body is impacted, the buffer part 3 can also absorb a part of the impulse, and the side wall 5 can further absorb the rest of the impulse, thereby effectively protecting the side of the flexible screen. In order to reduce the bending stress applied to the third protection portion 13 when the third protection portion 13 is folded, the buffer portion 3 is connected only to the first protection portion 11 and the second protection portion 12, and is not connected to the third protection portion 13.

Referring to fig. 3, in the present embodiment, the number of the buffer portions 3 is two, and the two buffer portions 3 are respectively connected to the first protection portion 11 and the second protection portion 12, and both partially surround the body 1. The buffer part 3 comprises a hollow projection 31, the interior of the projection 31 forms a channel 30 at least partially surrounding the body, and because the projection 31 is hollow, when the front surface of the terminal main body is impacted, the projection 31 acts like an air bag, can generate larger deformation amount, and can absorb larger impulse.

Optionally, the protection device 100 comprises a flow body 6, the flow body 6 being movably arranged in the channel 30. In this embodiment, the fluid 6 is a plurality of balls made of resin, and the end of the passage 30 is provided with a stopper to prevent the balls from separating from the passage 30. When the terminal body accident fell, a plurality of balls received the action of gravity and downstream to a apex angle department that is closest to ground, and the ball collides each other, and the heat that the collision produced can make that some surface that the ball collided melt and form the sol to slightly cohere a plurality of balls together, form one barricade, when the terminal body struck ground, most momentum can be absorbed to the barricade, thereby protect the side of flexible screen. The balls are only slightly bonded to each other and will separate and move along the channel 30 after impact, part of the impulse being converted into the momentum of the balls.

In order to further increase the adhesion degree between the balls, the surfaces of the balls can be coated with the flint powder or the gunpowder, when the balls collide, the flint powder or the gunpowder can release a large amount of heat, the surfaces of the balls made of resin are further melted to form more sol, and therefore the balls are firmly adhered. Of course, since the area of adhesion is still small, the balls will also separate after impact. Since the contact occurring at the time of the impact between the balls is similar to a point contact, the flint powder or the gunpowder coated on the other regions of the balls (regions where no collision occurs) can still function when the next fall occurs.

In other embodiments, the fluid may also be a liquid substance, such as water. Of course, it is necessary to ensure that the channel 30 is closed at this point. When the terminal body is dropped, the liquid substance moves to a vertex angle closest to the ground to form a retaining wall, and also can absorb most of the impulse.

The movement of the protection device when the terminal body is folded during the folding process is shown in fig. 4. With the second protector as a reference, the first protector 11 is rotated by 180 degrees around the center of the third protector 13, and the third protector 13 is deformed to have an approximately semi-cylindrical shape.

On the other hand, this application still provides a flexible screen terminal. Referring to fig. 5, the flexible screen terminal includes a terminal body 200 and the protection device 100 according to any of the embodiments described above. The terminal body 200 includes a housing 21, a flexible screen 22 mounted on the housing, and a circuit board, a processor, a memory, a battery, a cellular data module, etc. disposed in the housing. The flexible screen 22 includes a first display area 221, a second display area 222 and a third display area 223 connecting the first display area 221 and the second display area 222, the third display area is bent when the flexible screen is folded, and after the flexible screen is folded, the flexible screen 22 is located at the outer side, and the housing 21 is located at the inner side, so as to allow a user to view and operate the terminal body in a folded state. Accordingly, the housing 21 and other components are also designed to be foldable together with the Flexible screen 22, for example, a portion of the housing corresponding to the third display area is designed to be made of a Flexible material, a hard-to-fold portion of a processor, a memory, and the like can be disposed in a region corresponding to the first display area 221 or the second display area 222, and an FPC (Flexible printed Circuit Board) can be selected by a Circuit Board through an FFC (Flexible Flat Cable).

In addition to the body 1, the buffer portion 3 of the protection device 100 is used to protect the front and side edges of the flexible screen 22, the side wall 5 is also used to protect the side edges of the flexible screen 22, and the holding portion 4 is used to be fixed to the terminal body and to protect the back surface of the terminal body, so that the protection device 100 can organically protect the flexible screen 22 at each location where an impact or a shock may be applied.

No matter when terminal body 200 is expanded or folded, first protection portion 11, second protection portion 12, third protection portion 13 can both carry out effective protection to first display area 221, second display area 222, third display area 223 all the time, and because first protection portion 11, second protection portion 12, third protection portion 13 are made by transparent material, therefore do not influence the user and use, look over the cell-phone.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
