The protective sleeve can play a role in protecting the folding electronic equipment from scratch, falling and vibration, and can decorate the appearance of the folding electronic equipment. However, the present protective case has a certain defect, taking a folding mobile phone as an example, the protective case on the market can better wrap the mobile phone in a folding state. But in the mobile phone expansion state, because of the integrated design of the protective housing for the protective housing is when expansion state, and the width of protective housing is greater than the width that folding mobile phone was expanded, influences the aesthetic property and the use experience of protective housing. Some protective cases even show bulges in the unfolded state, which affects the use.

Disclosure of Invention

The application provides a folding protective sleeve which can be used for protecting folding electronic equipment, and can be well matched with the folding electronic equipment when the folding electronic equipment is in an unfolding state or a folding state, so that the folding protective sleeve can provide protection for the folding electronic equipment and improve the attractiveness and the using hand feeling of the folding protective sleeve.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme:

in a first aspect, the present application provides a folding protective case comprising a shaft protection structure and a housing assembly housing a folding electronic device, wherein the housing assembly comprises a first housing and a second housing, the first housing and the second housing being connected by the shaft protection structure. The housing assembly is switchable between an extended state and a collapsed state with the state of the foldable electronic device. The rotating shaft protection structure is in a stretching state when the shell assembly is switched from the unfolding state to the folding state, and the rotating shaft protection structure is in a natural state when the shell assembly is switched from the folding state to the unfolding state. When the rotating shaft protection structure is in a natural state, the sum of the width of the rotating shaft protection structure and the width of the first shell is equal to the width of the second shell; when the rotating shaft protection structure is in a stretching state, the stretching amount of the rotating shaft protection structure is equal to the thickness of the folded electronic equipment.

Therefore, the application can switch the shell assembly between the unfolding state and the folding state by arranging the rotating shaft protection structure so as to change along with the state of the folding electronic equipment, thereby realizing the protection of the folding electronic equipment. Because the rotating shaft protection structure has a stretching state and a natural state, the rotating shaft protection structure has stretchability, so that the overall length of the folding protective sleeve can be stretched to match the total length of the structure of the folding electronic equipment to be protected in different states. When the rotating shaft protection structure is in a natural state, the sum of the width of the rotating shaft protection structure and the width of the first shell is equal to the width of the second shell, the width of the folding protection sleeve is twice the width of the second shell, and the folding protection sleeve can be matched with the folding electronic equipment in an unfolding state by setting the width of the second shell to be half of the width of the folding electronic equipment in the unfolding state. When the rotating shaft protection structure is in a stretching state, the stretching amount of the rotating shaft protection structure is equal to the thickness of the folded electronic equipment, so that the width of the folding protection sleeve is twice the sum of the width of the second shell and the stretching amount of the rotating shaft protection structure, and at the moment, the folding protection sleeve can be matched with the folding electronic equipment in a folding state.

In the application, when the folding electronic equipment is in the unfolding state and the folding state, the folding protective sleeve can be matched with the folding electronic equipment, and when the folding electronic equipment is in the intermediate state between the unfolding state and the folding state, the folding protective sleeve can adaptively stretch the length of the rotating shaft protective structure according to the unfolding angle of the folding electronic equipment because the rotating shaft protective structure has stretchability, so that the folding protective sleeve can be matched with the folding electronic equipment. Thereby improving the aesthetic property and the using hand feeling of the folding protective sleeve while protecting the folding electronic equipment.

In one possible design of the first aspect, the shaft protection structure includes a folding structure, and the first housing and the second housing are connected by the folding structure. The folding structure is in a stretched state when the housing assembly is switched from the unfolded state to the folded state, and the folding structure is in a natural state when the housing assembly is switched from the folded state to the unfolded state.

In this way, the folding structure is arranged as the rotating shaft protection structure, so that folding is realized when the folding structure is in a stretching state to a natural state, and stretching is realized when the folding structure is in the stretching state to the natural state. The folding structure can achieve certain retractility, so that certain retractility is provided for the folding protective sleeve, and the folding protective sleeve can be matched with folding electronic equipment in different states.

In one possible design manner of the first aspect, the rotation shaft protection structure further includes a rotation shaft protection shell, one side of the rotation shaft protection shell is connected with the first shell through a folding structure, and the other side of the rotation shaft protection shell is connected with the second shell.

Therefore, the rotating shaft protection shell and the folding structure are adopted as the rotating shaft protection structure, and when the folding electronic equipment is in the folding state, the rotating shaft protection shell can protect the rotating shaft of the folding electronic equipment. When the folding electronic equipment is in the unfolding state, the rotating shaft protective housing can partially protect the machine body. The folding structure has retractility, so that the folding protective sleeve can be wholly retracted, and the folding protective sleeve can be matched with folding electronic equipment in different states.

In one possible design of the first aspect, the folding structure includes a first connector, a second connector, and one or more sets of telescoping assemblies. One end of the telescopic component is connected with the first connecting piece, and the other end of the telescopic component is connected with the second connecting piece. The telescopic assembly comprises a plurality of annular parts, wherein a first connecting part is connected with one annular part, a second connecting part is connected with the other annular part, and two adjacent annular parts are connected through a connecting strip. Wherein the width of the ring member increases from the initial width to the stretched width when the ring member is stretched under a force; the width of the ring member returns from the stretched width to the original width when the ring member is unstressed or squeezed

In this way, by arranging one or more groups of telescopic components, the whole telescopic performance of the folding structure can be realized, wherein the first connecting piece can be used for being connected with the first shell, and the second connecting piece can be used for being connected with the second shell. The width of the ring-shaped member is widened when the ring-shaped member is under tension; when the expansion assembly is not stressed or is stressed by extrusion force, the width of the expansion assembly is narrowed to restore to the initial state, and the expansion of the expansion assembly is realized. Through setting up a plurality of ring parts to adopt the connecting strip to link to each other the ring part, a plurality of ring parts can improve the flexible distance of flexible subassembly, so that folding type electronic equipment matches better for folding type protective sheath.

In one possible design of the first aspect, the folding structure includes a plurality of sets of telescopic assemblies, the plurality of sets of telescopic assemblies being arranged side by side. This design mode is a specific implementation mode of beta structure, through setting up multiunit flexible subassembly to set up it side by side, can improve the holistic elasticity of beta structure, simultaneously, can improve beta structure's density, so that form better protection to folded electronic equipment.

In one possible design of the first aspect, the plurality of sets of telescopic assemblies are integrally formed. Therefore, the processing of the folding structure is facilitated, and meanwhile, the strength of the folding structure can be improved.

In one possible embodiment of the first aspect, the ring element is circular, elliptical or polygonal. This design shows a specific shape of the ring. For example, when the ring member is circular, it may be stretched into an oval shape and restored to a circular shape. When the ring-shaped member is elliptical, it can be stretched into a circular shape and restored into an elliptical shape. When the annular piece is rectangular, the annular piece can be stretched into a diamond shape or an approximate diamond shape and restored into a rectangle.

In one possible embodiment of the first aspect, the ring element is rectangular, the connection points of the connecting strip and the ring element lie on a straight line, and the straight line bisects the ring element.

In this way, all the connection points of the connection strip and the annular piece are arranged on the same straight line, and the straight line bisects the annular piece, namely, the connection point of the connection strip and the annular piece is positioned at the middle point of one side edge of the annular piece, which is beneficial to improving the stretching amount of the annular piece, so that the stretching amount of the folding structure is improved, and the folding protective sleeve is better matched with the folding electronic equipment.

In one possible design of the first aspect, the first housing is provided with an accommodating space, one end of the folding structure is connected to a side wall of the accommodating space, and the other end of the folding structure is connected to the rotary shaft protective housing. When the shell assembly is in a folded state, the sum of the stretched length of the folded structure and the width of the first shell is equal to the width of the second shell. When the shell component is in an unfolding state, the folding structure is in a natural state, and the folding structure is positioned in the accommodating space.

Therefore, the accommodating space is arranged, so that the folding structure in the folded state is hidden, and the attractiveness of the folding protective sleeve in the unfolded state is improved. By arranging the housing assembly in a folded state, the sum of the stretched length of the folded structure and the width of the first housing is equal to the width of the second housing. The folding protective sleeve in the folding state can be matched with the folding electronic equipment in the folding state.

In one possible design of the first aspect, the sum of the width of the shaft protective housing and the width of the first housing is equal to the width of the second housing.

Therefore, the total width of the folding protective sleeve in the unfolded state is twice that of the second shell, and the folding protective sleeve can be matched with the folding electronic equipment by setting the width of the second shell to be half of that of the folding electronic equipment in the unfolded state.

In one possible design manner of the first aspect, the width of the hinge protection case is equal to the thickness of the folded electronic device.

Therefore, when the folding electronic equipment is in a folding state, the rotating shaft protection shell can protect the rotating shaft.

In one possible embodiment of the first aspect, the sum of the width of the folded structure in the natural state and the width of the first housing is equal to the width of the second housing.

In one possible design manner of the first aspect, when the folding structure is in the stretched state, the stretching amount of the folding structure is equal to the thickness of the folded folding electronic device.

Therefore, when the folding electronic equipment is in a folding state, the protection of the rotating shaft of the folding electronic equipment can be realized through the stretched part folding structure.

In one possible embodiment of the first aspect, the length of the folding structure is identical to the length of the first housing. Therefore, the length of the whole folding protective sleeve is consistent, and the attractive appearance of the folding electronic protective sleeve is improved.

In one possible embodiment of the first aspect, a cover plate is provided in the first housing, which is connected to the first housing and covers the receiving space.

An embodiment of the present application provides a foldable protective case 100 for protecting a foldable electronic device 10, where the foldable electronic device 10 includes a foldable screen mobile phone, a foldable screen tablet computer, a foldable screen notebook computer, and other electronic products such as a terminal device having a foldable screen.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a foldable electronic device in an unfolded state according to an embodiment of the present application, and fig. 2 is a schematic diagram of a foldable electronic device in a folded state according to an embodiment of the present application. The embodiment of the application is exemplified by a folding electronic device 10 as a folding screen mobile phone.

As shown in fig. 1, the foldable electronic device 10 includes a first portion 11 and a second portion 12, where the first portion 11 and the second portion 12 are connected by a rotating shaft 13 and can relatively rotate to realize unfolding and folding, and in fig. 1, the first portion 11 and the second portion 12 are in an unfolded state. In the embodiment of the present application, the width of the first portion 11 is equal to the width of the second portion 12, the length of the first portion 11 is equal to the length of the second portion 12, and the length of the first portion 11 is equal to the length of the second portion 12. Let the width of the first portion 11 and the second portion 12 be w, the length of the first portion 11 and the second portion 12 be l, and the thickness of the first portion 11 and the second portion 12 be h. Then the width of the folded electronic device 10 after being unfolded is 2w and the thickness of the folded electronic device 10 after being unfolded is h, as shown in fig. 1.

As shown in fig. 2, the first portion 11 and the second portion 12 are shown in fig. 2 in a folded state. Since the first portion 11 and the second portion 12 are stacked together, the first portion 11 and the second portion 12 are identical in size and structure. In fig. 2, the folded width of the foldable electronic device 10 is w, and the folded thickness of the foldable electronic device 10 is 2h.

It should be noted that, in the embodiment of the present application, the unfolded state mainly refers to the fully unfolded state (the angle between the two is 180 °), the folded state mainly refers to the fully folded state (the angle between the two is 0 °), and 0 ° and 180 ° are two extreme values of folding and unfolding of the foldable electronic device 10, and these two states are taken as examples for convenience in description and understanding. Of course, the folded state and the unfolded state may also include states at other angles, for example, a hovering state at an angle between the first portion 11 and the second portion 12, including: 30 °, 45 °, 60 °, 90 °, 120 °, 135 °, 150 °, etc. Hereinafter, the folded state and the unfolded state of the foldable protection sleeve 100 are the same, and a detailed description thereof will be omitted.

The foldable protection sleeve 100 provided in the embodiment of the present application is used for protecting the foldable electronic device 10, and generally speaking, the foldable protection sleeve 100 is used for covering a side, not provided with a folding screen, of the foldable electronic device 10 and a middle frame, and the state of the foldable protection sleeve 100 can be changed along with the state of the foldable electronic device 10, so that the state of the foldable protection sleeve 100 is consistent with the state of the foldable electronic device 10. That is, when the foldable electronic device 10 is in the unfolded state, the foldable protective sleeve 100 is also in the unfolded state; when the foldable electronic device 10 is in the folded state, the foldable protective sleeve 100 is also in the folded state.

Since the foldable electronic device 10 needs to be covered by the foldable electronic device 100 regardless of the state of the foldable electronic device 10, the length of the body of the foldable electronic device that needs to be covered is different in different states when the foldable electronic device is folded. As shown in fig. 1, when the foldable electronic device 10 is in the unfolded state, the hinge 13 portion of the foldable electronic device 10 is hidden, the width of the foldable electronic device 10 is 2w, and the length that needs to be covered is 2w. As shown in fig. 2, when the foldable electronic device 10 is in the folded state, the rotation shaft 13 of the foldable electronic device 10 is partially exposed, the foldable electronic device 10 has a width w and a thickness 2h, and the length of the foldable electronic device 10 to be covered is 2w+2h.

If the foldable protection sleeve 100 is designed to have a fixed length, for example, a length of 2w, the foldable electronic device 10 cannot be folded when placed in the foldable protection sleeve 100, and is always in an unfolded state. For another example, if the length is 2w+2h, the foldable electronic device 10 may be well covered by the foldable electronic device 100 when the foldable electronic device is in the folded state after the foldable electronic device is placed in the foldable protective sleeve 100. However, when the foldable electronic device 10 is in the unfolded state, since the width of the foldable electronic device 10 is 2w, which is less than the length 2w+2h of the foldable protective sleeve 100, the protective sleeve with 2h length becomes redundant in the unfolded state, and forms a protrusion, resulting in poor use experience.

In order to solve the problem, the embodiment of the present application provides a foldable protection sleeve 100, which can cover the foldable electronic device 10 in various states, and does not generate redundancy, so that the foldable protection sleeve 100 can be attached to the foldable electronic device 10 in various angles.

Referring to fig. 3, fig. 3 is a schematic view of a foldable protection sleeve in an unfolded state according to an embodiment of the present application. As shown in fig. 3, the foldable protective sleeve 100 includes a housing assembly and a rotation shaft protection structure 130, wherein the housing assembly includes a first housing 110 and a second housing 120, and the first housing 110 and the second housing 120 are connected by the rotation shaft protection structure 130.

The shaft protection structure 130 may be telescopic, so that the width of the entire folding type protective case 100 may also be telescopic. The hinge protection structure 130 is configured to protect the first portion 11 or the second portion 12 of the foldable electronic device 10 when the foldable electronic device 10 is in the unfolded state; when the foldable electronic device 10 is in a folded state, the hinge protection structure 130 is used for protecting the hinge 13 exposed after the foldable electronic device 10 is folded, so that the foldable protection sleeve 100 can cover the foldable electronic device 10 in different states.

The housing assembly is configured to house the foldable electronic device 10, and in particular, the first portion 11 of the foldable electronic device 10 may be disposed in the first housing 110 and the second portion 12 of the foldable electronic device 10 may be disposed in the second housing 120. The first housing 110 and the second housing 120 may set positions according to the display screen of the foldable electronic device 10, and open windows at corresponding positions, so that the foldable protection sleeve 100 does not affect the display of the display screen of the foldable electronic device 10.

For example, folding screens are provided on the first face of the first portion 11 and the first face of the second portion 12 of the foldable electronic device 10, the second face of the first portion 11 of the foldable electronic device 10 is provided with a back plate, and one side of the back plate is provided with a camera set, and the second face of the second portion 12 of the foldable electronic device 10 is provided with a separate display screen. A bottom plate may be provided on one side of the first housing 110 and an imaging aperture 1103 may be provided in the floor so as to expose the camera group on the back plate side of the first portion 11. The two sides of the second housing 120 are hollowed out, so that the second housing 120 only covers the middle frame of the second portion 12 of the foldable electronic device 10, the screen window 1201 on one side of the second housing 120 is used for exposing the folding screen arranged on the second portion 12, and the screen window 1201 on the other side of the second housing 120 is used for exposing the separate display screen arranged on the second portion 12, so that the display screens on the two sides of the second portion 12 are not covered.

After the first housing 110 and the second housing 120 are connected through the hinge protection structure 130, when the foldable electronic device 10 is placed in the first housing 110 and the second housing 120, the first housing 110 and the second housing 120 can be switched between an unfolded state and a folded state along with the state of the foldable electronic device 10, so that the state of the housing assembly (the first housing 110 and the second housing 120) is consistent with the state of the foldable electronic device 10.

Since the foldable electronic device 10 is changed in state, the length of the foldable electronic device that needs to be covered by the foldable protection sleeve 100 changes. In the foldable protection sleeve 100, the dimensions of the first housing 110 and the second housing 120 are generally fixed, so that the foldable protection sleeve 100 provided in the embodiment of the application mainly adjusts the overall length of the foldable protection sleeve 100 by adjusting the length of the rotating shaft protection structure 130, so that the foldable electronic device 10 with a width to be covered in a variable condition can be covered.

Specifically, embodiments of the present application adjust the overall length of the folded sleeve 100 by stretching the width of the shaft protection structure 130. When the foldable electronic device 10 is switched from the unfolded state to the folded state, the first housing 110 and the second housing 120 are also switched from the unfolded state to the folded state, and the width of the foldable electronic device 10 to be covered is the longest, which is 2w+2l. Correspondingly, the overall length of the foldable protection sleeve 100 is also the longest, at this time, the rotation shaft protection structure 130 is in a stretched state, and the stretching amount of the rotation shaft protection structure 130 is the greatest.

When the foldable electronic device 10 is switched from the folded state to the unfolded state, the first housing 110 and the second housing 120 are also switched from the folded state to the unfolded state, and at this time, the portion of the rotating shaft 13 of the foldable electronic device 10 is folded and hidden, and the width of the portion to be covered is the shortest, which is 2w. Correspondingly, the overall length of the foldable protection sleeve 100 is also the shortest, and at this time, the rotation shaft protection structure 130 is in a natural state. That is, when the housing assembly is in the unfolded state, the hinge protection structure 130 may be in the natural state, and the total width of the foldable electronic device 10 may be equal to the width of the foldable electronic device 10 in the unfolded state, and the foldable electronic device 10 may be wrapped in the foldable protective sleeve 100.

That is, in the process of switching the foldable electronic device 10 from the unfolded state to the folded state, the width of the foldable electronic device 10 to be covered gradually increases, and when the foldable electronic device 10 is switched from the unfolded state to the folded state, the width of the foldable electronic device 10 to be covered is also maximized. Meanwhile, in the process of switching the housing assembly from the unfolded state to the folded state, the rotation shaft protection structure 130 is in a stretched state, the stretching amount of the rotation shaft protection structure 130 gradually becomes larger, and when the housing assembly is switched from the unfolded state to the folded state, the stretching amount of the rotation shaft protection structure 130 is maximum.

In the process of switching the foldable electronic device 10 from the folded state to the unfolded state, the width of the foldable electronic device 10 to be covered gradually decreases, and when the foldable electronic device 10 is switched from the folded state to the unfolded state, the width of the foldable electronic device 10 to be covered is minimum. In the process of switching the housing assembly from the folded state to the unfolded state, the rotating shaft protection structure 130 is also in a stretched state, the stretching amount of the rotating shaft protection structure is gradually reduced, when the housing assembly is switched from the folded state to the unfolded state, the rotating shaft protection structure 130 is restored to the natural state, and at the moment, the width of the foldable electronic device 10 which needs to be covered is also minimum.

The overall width of the foldable electronic device 10 and the width to be covered are both 2w in the unfolded state, and w if the first portion 11 and the second portion 12 of the foldable electronic device 10 are the same. The housing assembly changes with the state of the foldable electronic device 10, and is in the unfolded state at this time, that is, the width of the foldable protective sleeve 100 in the unfolded state is also 2w (neglecting the thickness of the housing material), and the shaft protection structure 130 has a certain width in both the natural state and the stretched state. Therefore, the width of both the first and second cases 110 and 120 cannot be set to w, otherwise the width of the folded-out case 100 in the unfolded state would exceed 2w.

In the embodiment of the present application, the rotation shaft protection structure 130 includes a folding structure 131, the first housing 110 and the second housing 120 are connected by the folding structure 131, the folding structure 131 is in a stretched state when the housing assembly is switched from the unfolded state to the folded state, and the folding structure 131 is in a natural state when the housing assembly is switched from the folded state to the unfolded state. By arranging the folding structure 131, the rotating shaft protection structure 130 can be telescopic, and the whole folding protection sleeve 100 can be telescopic. When the widths of the first and second cases 110 and 120 are set, the width of one case is set to w, and the sum of the width of the other case and the width of the rotation shaft protection structure 130 in a natural state is set to w, so that the total width of the folding type protective case 100 in an unfolded state is 2w.

As an example, as shown in fig. 3, the sum of the width of the first housing 110 and the width of the folded structure 131 in a natural state is set to be equal to the width of the second housing 120. That is, the sum of the width of the first housing 110 and the width of the folded structure 131 in the natural state is set to w, and the width of the second housing 120 is set to w.

With the above arrangement, the first part 11 of the foldable electronic device 10 can be placed in the first housing 110 of the foldable protective sleeve 100, wherein the first part 11 is protected by the first housing 110 together with the folded structure 131 in its natural state. The second portion 12 of the foldable electronic device 10 may be placed in the second housing 120 of the foldable protective sleeve 100, with the second portion 12 being protected by the second housing 120. Therefore, the width of the protective sleeve of the rotating shaft 13 in the unfolding state is adapted to the width of the folding electronic equipment 10 in the unfolding state, so that the folding electronic equipment 10 is protected, and meanwhile, no bulge is generated, and the folding electronic equipment has good using hand feeling.

When the foldable electronic device 10 is in the folded state, since the foldable protective cover 100 needs to protect not only the widths of the first portion 11 and the second portion 12 but also the rotation shaft 13 exposed by the foldable electronic device 10 in the folded state. Therefore, the total width of the folding type protective sheath 100 (the sum of the width of the first housing 110, the width of the second housing 120, and the width of the folding structure 131) in the folded state also needs to be widened.

Referring to fig. 4, fig. 4 is a schematic view of a foldable protection sleeve in a folded state according to an embodiment of the present application. After the foldable electronic device 10 is placed in the foldable protective sleeve 100, the second portion 12 is protected by the second housing 120, since the first portion 11 is protected by the first housing 110 and the folded structure 131. When the foldable electronic device 10 is in the folded state, the foldable electronic device 10 in the folded state can be protected by the foldable protection sleeve 100 mainly by stretching the foldable structure 131.

As shown in fig. 4, when the foldable protection sleeve 100 is in the folded state, the folding structure 131 is in the stretched state, and the stretching amount is the largest at this time, and since the width of the first housing 110 is smaller than the width (w) of the first portion 11 of the foldable electronic device 10, a part of the folding structure 131 and the first housing 110 together form a protection for the first portion 11 of the foldable electronic device 10, and the rest of the folding structure 131 is used for protecting the rotating shaft 13 of the foldable electronic device 10. Since the sum of the width of the folded structure 131 in the natural state and the width of the first housing 110 is the same as the width of the second housing 120, both are w. And the sum of the width of the stretched folded structure 131 and the first housing 110 is equal to the sum of the width of the first portion 11 and the thickness of the electronic device after being folded. That is, the stretching amount (maximum stretching amount) of the folding structure 131 when the folding type protective cover 100 is in the folded state is equal to the thickness (2 h) of the electronic device after folding.

At this time, the total width of the foldable protecting case 100 is also the maximum width (2w+2h), which is the same as the width (2w+2h) of the foldable electronic device 10 that needs to be covered in the folded state, so that the foldable protecting case 100 can form a good protection for the foldable electronic device 10. In addition, when the foldable electronic device 10 is between the unfolded state and the folded state, the foldable protection sleeve 100 may also change along with the state of the foldable electronic device 10, and correspondingly, the stretching amount of the folding structure 131 also changes along with the state of the foldable electronic device 10, so as to match the width of the foldable electronic device 10 that needs to be covered in different states. For example, when the foldable electronic device 10 hovers at 120 °, at this time, the foldable protective sleeve 100 also hovers at 120 °. The width of the foldable electronic device 10 to be covered is between 2w and 2w+2h, and correspondingly, the stretching amount of the foldable structure 131 is smaller than the thickness 2h of the foldable electronic device 10 in the folded state, the stretching amount of the foldable structure 131 is matched according to the state of the electronic device, and the stretching amount of the foldable structure 131 is 0 to 2h.

In addition, since the first case 110 and the second case 120 are directly connected through these structures, for the aesthetic appearance of the folding type protective case 100, the folding structure 131 may be provided to have the same length as the first case 110 and the second case 120, so that the folding structure 131 may be maintained flush with the first case 110 and the second case 120 regardless of the folded state or the unfolded state, increasing the aesthetic appearance of the folding type protective case 100.

The embodiment of the application sets the rotating shaft protection structure 130 with the folding structure 131, so that the whole length of the folding type protective sleeve 100 has elasticity, the folding type protective sleeve 100 can be matched with the shape of the folding type electronic equipment 10 in both a folding state and an unfolding state, and the folding type protective sleeve can form good protection and can not generate redundant structures because the different shapes of the folding type electronic equipment 10 need to be covered with different lengths, thereby influencing the use experience.

In an embodiment of the present application, the shaft protection structure 130 further includes a shaft protection shell 132. Referring to fig. 5, fig. 5 is a schematic view of another foldable protection sleeve in an unfolded state according to an embodiment of the present application. As shown in fig. 5, the rotation shaft protection structure 130 includes a folding structure 131 and a rotation shaft protection housing 132, wherein one side of the rotation shaft protection housing 132 is connected with the first housing 110 through the folding structure 131, and the other side of the rotation shaft protection housing 132 is connected with the second housing 120.

Since the hinge protection structure 130 includes the folding structure 131, the width of the hinge protection structure 130 can be stretched by stretching the folding structure 131, so that the whole width of the folding protection sleeve 100 can be stretched, and the folding electronic device 10 in different states can be protected.

In the embodiment of the present application, since the hinge protection shell 132 is provided, when the foldable electronic device 10 is in the folded state, the hinge protection shell 132 can be controlled to be in the area corresponding to the hinge 13 in the foldable electronic device 10, so that the hinge protection shell 132 protects the hinge 13 in the foldable electronic device 10. Accordingly, the width of the hinge protective case 132 may be set to be equal to the thickness of the folder type electronic device 10 in the folded state. When the foldable electronic device 10 is in the unfolded state, the width of the foldable electronic device 10 to be protected is the width of the first portion 11 and the width of the second portion 12 is 2w, and the width of the foldable electronic device 10 to be covered is the shortest. Accordingly, the folded structure 131 can be placed in a natural state (without stretching) when in an unfolded state. That is, when the rotation shaft protective case 132 is provided, the total width of the folding protective case 100 (the sum of the width of the first housing 110, the width of the rotation shaft protective case 132, the width of the folding structure 131 in the natural state, and the width of the second housing 120) is also 2w in the unfolded state.

As an example, as shown in fig. 5, the width of the second case 120 may be set to w, and the sum of the width of the rotation shaft protective case 132, the width of the folding structure 131 in the natural state, and the width of the first case 110 may be set to w. So that the overall width of the foldable protective sleeve 100 in the unfolded state matches the overall width of the foldable electronic device 10 in the unfolded state.

With the above arrangement, the first portion 11 of the foldable electronic device 10 can be placed in the first housing 110 of the foldable protective case 100, wherein the first portion 11 is protected by the first housing 110, the folded structure 131 in the natural state and the rotary shaft protective case 132 together. The second portion 12 of the foldable electronic device 10 may be placed in the second housing 120 of the foldable protective sleeve 100, with the second portion 12 being protected by the second housing 120. Therefore, the width of the folding protective sleeve 100 in the unfolded state is adapted to the width of the folding electronic equipment 10 in the unfolded state, so that the folding electronic equipment 10 is protected, and meanwhile, no bulge is generated, and the folding protective sleeve has good using hand feeling.

In the unfolded state, the first housing 110, the folded structure 131 in the natural state and the rotary shaft protecting shell 132 form protection for the first part 11, but the first part 11 of the folding device can also play a good role in protection, but in the unfolded state, the corresponding protection structure is too many, and the appearance is not attractive. Accordingly, the folded structure 131 in a natural state may be hidden in the first housing 110 such that the folded protective case 100 in an unfolded state forms a protection for the first portion 11 by the first housing 110 and the rotary shaft protective case 132.

Specifically, referring to fig. 6, fig. 6 is a schematic structural diagram of a first housing 110 in another foldable protection sleeve according to an embodiment of the present application. As shown in fig. 5 and 6, an accommodating space 1101 is provided on the first housing 110, one end of the folding structure 131 is connected to a sidewall of the accommodating space 1101, and the other end of the folding structure 131 is connected to the rotating shaft protecting case 132. In order not to affect the appearance of the foldable protection sleeve 100, the accommodating space 1101 is generally formed on a surface of the first housing 110 contacting the foldable electronic device 10. When the housing assembly of the folding type protective sheath 100 is in the unfolded state, that is, when the folding structure 131 is in the natural state, the folding structure 131 is located in the accommodation space 1101. At this time, the rotary shaft protecting case 132 abuts against the first housing 110. Accordingly, when the accommodation space 1101 is provided, the width of the accommodation space 1101 may be provided to be equal to the width of the folded structure 131 in a natural state.

When the foldable protection sleeve 100 is in the unfolded state, the width of the foldable electronic device 10 that the foldable protection sleeve 100 needs to protect is 2w, since the width of the folded structure 131 in the natural state is hidden in the accommodating space 1101, the hinge protection shell 132 abuts against the first housing 110, and the first housing 110 and the hinge protection shell 132 form protection for the first portion 11, and the second housing 120 forms protection for the second portion 12. Accordingly, the sum of the width of the rotation shaft protective case 132 and the width of the first housing 110 may be set to w, and the width of the second housing 120 may be set to w, such that the sum of the width of the rotation shaft protective case 132 and the width of the first housing 110 is equal to the width of the second housing 120. Accordingly, the overall width of the foldable protective sleeve 100 in the unfolded state is 2w, which matches the overall width of the foldable electronic device 10 in the unfolded state.

At this time, the folding structure 131 is in a natural state, and the folding structure 131 is received in the receiving space 1101 on the first housing 110, in other words, the folding structure 131 is stacked on the first housing 110. Since the folding structure 131 is disposed in the accommodating space 1101 on the first housing 110, when the foldable electronic device 10 is mated with the foldable protection sleeve 100, a part of the body of the foldable electronic device 10 (such as the first portion 11 mentioned above) is also disposed in the first housing 110. In order to avoid the interference of the folding structure 131 to the machine body, when the accommodating space 1101 is provided, the depth of the accommodating space 1101 may be the same as the thickness of the folding mechanism, so that the folding mechanism may be kept flat with the surface of the first housing 110 after being placed in the accommodating space 1101. Thereby reducing the influence on the body placed in the first housing 110.

Referring to fig. 7, fig. 7 is another schematic view of another foldable protection sleeve in an unfolded state according to an embodiment of the present application. Since the accommodation space 1101 is formed in the first housing 110 and the folding structure 131 is provided in the accommodation space 1101, the external appearance of the folding type protective case 100 may be affected to some extent. Therefore, for the aesthetic appearance of the folding type protective case 100, a cover sheet 1102 may be provided on the first case 110, as shown in fig. 7, the cover sheet 1102 is attached to the first case 110, and the cover sheet 1102 may cover the accommodation space 1101, and at the same time, may cover the folding structure 131 in the accommodation space 1101. The accommodating space 1101 and the folding structure 131 are prevented from affecting the appearance of the folding type protective case 100, and at the same time, the folding structure 131 is prevented from interfering with the body placed in the first housing 110.

When the foldable protection sleeve 100 is in the folded state, reference may be made to fig. 8, and fig. 8 is a schematic diagram of another foldable protection sleeve in the folded state according to an embodiment of the present application. As shown in fig. 8, when the folding type protective case 100 is in the folded state, the folding structure 131 is stretched so that the hinge protective case 132 moves to the hinge 13 area of the folding type electronic device 10. Wherein the second housing 120 protects the second portion 12 of the foldable electronic device 10, the hinge protective housing 132 protects the hinge 13 area of the foldable electronic device 10, and the first housing 110 and the stretched folded structure 131 protect the first portion 11 of the foldable electronic device 10.

At this time, the folded structure 131 is in a stretched state, and the stretching amount is the maximum value. Accordingly, the sum of the width of the first housing 110 and the maximum amount of stretching of the folding structure 131 is equal to the width of the first portion 11 of the folding electronic device 10, w, and equal to the width of the second housing 120. In the unfolded state, the sum of the width of the rotary shaft protecting shell 132 and the width of the first shell 110 is w, which is easy to obtain, when the foldable protecting sleeve 100 is in the folded state, the stretching amount of the folding structure 131 is equal to the width of the rotary shaft protecting shell 132. The hinge protection case 132 is used for protecting the foldable electronic device 10 in the folded state, so that the width of the hinge protection case 132 can be set to be the thickness of the foldable electronic device 10 in the folded state: 2h.

In the embodiment of the present application, since the folding structure 131 is disposed in the accommodation space 1101, for the aesthetic appearance of the folding type protective case 100, the length of the hinge protective case 132 may be the same as the lengths of the first case 110 and the second case 120, so that the hinge protective case 132 is maintained flush with the first case 110 and the second case 120 when the folding type protective case 100 is in the unfolded state, and the hinge protective case 132 is maintained in contact with both the first case 110 and the second case 120, so that the first case 110, the hinge protective case 132, and the second case 120 look like one body, increasing the aesthetic appearance of the folding type protective case 100.

Since one end of the folding structure 131 is connected to the sidewall of the accommodation space 1101 and the other end is connected to the rotation shaft protecting case 132, the length of the folding structure 131 can be set to be the same as the length of the accommodation space 1101, and the length of the folding structure 131 can be set as close as possible to the length of the first housing 110. When the foldable protection sleeve 100 is in the folded state (i.e. the folded structure 131 is in the unfolded state), the folded structure 131 will not have a too large gap with the first housing 110 and the rotary shaft protection housing 132 in the length direction, so as to ensure the beauty of the foldable protection sleeve 100 in the folded state as much as possible.

In the above embodiment, by providing the hinge protection shell 132 and the folding structure 131 as the hinge protection structure 130, the width of the hinge protection structure 130 may need to be extended and contracted, so that the width of the folding protection sleeve 100 may be well matched with the width of the folding electronic device 10 that needs to be covered, whether the folding electronic device 10 is in a folded state or an unfolded state. So that the foldable protection sleeve 100 can be well attached to the foldable electronic device 10, in various states, the foldable protection sleeve 100 does not have redundant structural protrusions, and good experience during use is ensured.

In the embodiment of the present application, no matter only the folding structure 131 is adopted as the rotating shaft protection structure 130, or the folding structure 131 and the rotating shaft protection shell 132 are adopted to form the rotating shaft protection structure 130 together, the expansion and contraction of the rotating shaft protection structure 130 are mainly realized through the folding structure 131, that is, the expansion and contraction of the folding protection sleeve 100 are mainly realized through the folding structure 131. The retractility of the folding structure 131 can be achieved by providing a telescoping structure that can be stretched or compressed. In the present application, the folding structure 131 may be stretched, and may be restored to a natural state after being stretched, thereby achieving the extension and retraction of the rotation shaft protection structure 130. The specific structure of the folding structure 131 will be described below.

Referring to fig. 9 and 10, fig. 9 is a schematic view of a part of a folded structure 131 in a folded protective sleeve in an unfolded state according to an embodiment of the present application, and fig. 10 is a schematic view of a part of a folded structure 131 in a folded state according to an embodiment of the present application. As shown in fig. 9 and 10, the folding structure 131 includes a first connector 1311, a second connector 1312, and a telescoping assembly 1313. One end of the telescopic component 1313 is connected with the first connecting piece 1311, the other end of the telescopic component 1313 is connected with the second connecting piece 1312, and the telescopic component 1313 and the first connecting piece 1311 can be connected by welding, gluing or the like, or can be integrally formed. The telescopic assembly 1313 and the second connecting piece 1312 can be connected by welding, gluing or the like, or can be integrally formed.

The first connecting piece 1311 is used to connect with the first housing 110, and the second connecting piece 1312 is used to connect with the second housing 120/the shaft protecting shell 132, specifically, may be connected by gluing or welding. Alternatively, the first connector 1311 is used to connect to the second housing 120/the shaft protecting case 132, and the second connector 1312 is used to connect to the first housing 110, specifically, by gluing or welding.

It should be noted that, the telescopic components 1313 may be provided with one or more groups, and the plurality of groups of telescopic components 1313 and the one group of telescopic components 1313 are provided to provide good retractility for the folding structure 131, which has the same working principle, but the plurality of groups of telescopic components 1313 may provide better connection strength, and in the embodiment of the present application, the description is given by taking the folding structure 131 provided with the plurality of groups of telescopic components 1313 as an example.

As shown in fig. 9 and 10, the folding structure 131 includes a plurality of sets of telescopic members 1313, and the plurality of sets of telescopic members 1313 are disposed side by side. The multiple sets of telescoping assemblies 1313 may be integrally formed, or each set of telescoping assemblies 1313 may be separately provided. In the embodiment of the application, a mode of integrally forming a plurality of groups of telescopic assemblies 1313 is adopted, so that the processing is convenient, and the strength of the whole telescopic assemblies 1313 can be improved.

Specifically, each set of telescoping assemblies 1313 includes a plurality of annular members 1314, a first connector 1311 coupled to one of the annular members 1314, a second connector 1312 coupled to the other annular member 1314, and two adjacent annular members 1314 coupled by a connector strip 1315. Each loop 1314 has some ability to deform, the loop 1314 increasing in width from an initial width to a stretched width when the loop 1314 is stretched under a force; the loop 1314 resumes its width from the stretched width to the original width when unstressed or squeezed.

When the first and second links 1311 and 1312 are pulled by the first and second cases 110 and 120 to move in a direction away from each other, the first and second links 1311 and 1312 pull the plurality of ring members 1314 connected therebetween, causing the ring members 1314 to deform to a certain extent, so that the entire folded structure 131 is stretched, and the form of the folded structure 131 is as shown in fig. 10.

When the first and second links 1311 and 1312 are pushed by the first and second cases 110 and 120 to move in a direction approaching each other, the first and second links 1311 and 1312 push the plurality of ring-shaped members 1314 connected therebetween, so that the ring-shaped members 1314 return to the shape in the natural state, thereby returning the entire folding structure 131 to the natural state, and the form of the folding structure 131 is as shown in fig. 9.

It should be noted that, the ring member 1314 connected to the first connecting member 1311 may be a complete ring member 1314 or may be a part of the ring member 1314; the ring member 1314 connected to the second connecting member 1312 may be a complete ring member 1314 or may be a part of the ring member 1314. As shown in fig. 9 and 10, for example, the ring member 1314 connected to the first connecting member 1311 is a half ring member 1314, and the ring member 1314 connected to the second connecting member 1312 is a half ring member 1314. The use of the complete loop 1314 or the partial loop 1314 to connect with the first connector 1311/second connector 1312 does not affect the stretching and folding functions of the folding structure 131.

In one embodiment of the present application, the ring member 1314 may be provided in a circular, oval, or polygonal shape, for example, in a rectangular, square, pentagonal, hexagonal, octagonal, decagonal, etc., as well as other irregular polygons.

By way of example, if the ring member 1314 is circular in nature, its initial width is the diameter of the circle; it may become oval after being stretched and its stretched width is the length of the major axis of the oval. If the ring member 1314 is elliptical in its natural state, its initial width is the length of the minor axis of the ellipse, it may become circular after being stretched, and its stretched width is the diameter of the circle.

Referring to fig. 11, fig. 11 is a schematic structural view of an annular member in a foldable protection sleeve according to an embodiment of the present application. As shown in fig. 11, in the embodiment of the present application, when the foldable protection sleeve 100 is in the unfolded state, the ring-shaped member 1314 is in the natural state and has a rectangular shape. At this time, the initial width of the ring 1314 is the width of a rectangle. When the folding type protective sheath 100 is in a folded state, the ring-shaped member 1314 is in a stretched state, and the shape thereof is a diamond or a shape similar to the diamond after being stretched, such as the shape of the ring-shaped member 1314 in fig. 10. At this time, the stretching width of the ring 1314 is the length of one diagonal line of the diamond shape, which is shorter than the width of the rectangle. When the folding type protective sheath 100 is switched from the folded state to the unfolded state, the ring 1314 is restored from the stretched state to the natural state, and its shape is restored from the diamond shape to the rectangular shape.

Since the ring 1314 needs to be continuously switched between the stretched state and the natural state. Therefore, the material of the ring member 1314 needs to have good deformability and good strength. In an embodiment of the present application, the ring member 1314 may be made of stainless steel or a hard polycarbonate (pc) material.

In addition, each ring 1314 has good deformation in order to ensure that the folded structure 131 is in a stretched state. When two adjacent ring members 1314 are connected by the connecting bar 1315, the connecting bar 1315 and the connection point of the ring members 1314 may be disposed on the same straight line, and the straight line bisects all the ring members 1314. For example, when the ring member 1314 is rectangular, the connection point of the connection bar 1315 to the ring member 1314 may be set to be the midpoint of the side where the two ring members 1314 approach each other.

In the embodiment of the present application, the expansion and contraction of the folding structure 131 are realized by arranging a plurality of ring-shaped members 1314 with deformation capability, so that the expansion and contraction of the whole folding protection sleeve 100 is realized, and the expansion and contraction of the folding protection sleeve 100 are distributed to the plurality of ring-shaped members 1314, so that the deformation amount of each ring-shaped member 1314 is not too large, and the ring-shaped member 1314 can be made of a material with a certain strength. The folding structure 131 is ensured to have elasticity and simultaneously, the use strength thereof is ensured, so that the whole folding type protective sleeve 100 also has good strength. Meanwhile, due to the retractility provided by the folding structure 131, the folding protective sleeve 100 can be well attached to the folding electronic device 10, and in various states, the folding protective sleeve 100 does not have redundant structural protrusions, so that good experience in use is ensured.
