In the following description, the same drawings refer to the same or similar elements unless otherwise described. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] The present disclosure proposes a hinge cover of a folding terminal, the hinge cover comprising at least a first layer and a second layer, the first layer and the second layer being stacked along a thickness direction of the hinge cover, the hinge cover being configured to cover a folding hinge of the folding terminal, a side of the second layer opposite to the first layer being configured to face the folding hinge, and a material of the second layer being configured to be different from a material of the first layer.

[0029] In the embodiments of the present disclosure, the hinge cover is configured to have a stacked structure of the first layer and the second layer, and the first layer and the second layer are made of different materials, so that the first layer and the second layer have different characteristics, and the hinge cover has different characteristics along the thickness direction, thereby meeting the high requirements on the multiple characteristics of the hinge cover.

[0030] The folding terminal in the present disclosure refers to a terminal device having a folding structure, such as a folding screen mobile phone. The folding terminal generally realizes the folding function through a folding hinge, the folding hinge comprising a first folding part and a second folding part that can be folded relative to each other, the first folding part and the second folding part being connected through a folding hinge and being rotatable relative to the folding hinge. The hinge cover is covered on the folding hinge, configured to protect and support the folding hinge, and also to beautify the appearance of the folding hinge.

[0031] Figure 1 is a structural schematic diagram of a hinge cover according to an exemplary embodiment, Figure 2 is a cross-sectional structural schematic diagram of a hinge cover according to an exemplary embodiment, as Figure 1 , Figure 2 shown, the hinge cover comprises at least a first layer 1 and a second layer 2, the first layer 1 and the second layer 2 being stacked along a thickness direction of the hinge cover, the hinge cover being configured to cover a folding hinge of the folding terminal, a side of the second layer 2 opposite to the first layer 1 being configured to face the folding hinge, and a material of the second layer 2 being configured to be different from a material of the first layer 1.

[0032] In the embodiments of the present disclosure, the first layer 1 and the second layer 2 are made of different materials, so that the first layer 1 and the second layer 2 have different properties, and the shaft cover has different properties in the thickness direction, thereby meeting the high requirements of the folding terminal on the shaft cover.

[0033] In some embodiments, the shaft cover can also have an indefinite number of layers other than the first layer 1 and the second layer 2, and the other layers can also be made of materials different from the first layer 1 and the second layer 2, so that the shaft cover obtains more properties. Of course, the other layers can also be made of the same material as the first layer 1 or the second layer 2.

[0034] In some embodiments, the material of the second layer 2 is set to be different from the material of the first layer 1, which means that the first layer 1 and the second layer 2 have different materials, but does not exclude that the first layer 1 and the second layer 2 have partially the same material.

[0035] In some embodiments, the first layer 1 and the second layer 2 can be made of a single material respectively, or can be made of a combined material respectively. The use of a combined material means the use of two or more materials in a splicing or laminating manner, but does not necessarily mean the generation of a new material.

[0036] In some embodiments, as shown in FIG. 1, Figure 2 The first layer 1 is applied to the surface layer of the shaft cover, that is, when the shaft cover is assembled on the folding shaft, the first layer 1 is the appearance part that can be directly viewed by the user. Therefore, by using different materials to make the first layer 1 and the second layer 2, the appearance layer and the inner layer of the shaft cover can have different properties to meet the requirements of the folding terminal on the strength, weight, and appearance of the shaft cover.

[0037] In some embodiments, the deformation resistance of the second layer 2 is greater than that of the first layer 1, and the second layer 2 supports the first layer 1.

[0038] In the embodiments of the present disclosure, the layer with stronger deformation resistance is used as the second layer 2, which is beneficial to improve the overall strength of the shaft cover. At the same time, the deformation resistance of the first layer 1 as the appearance layer is lower than that of the second layer 2, which is beneficial to reduce the processing difficulty of the appearance shape.

[0039] In some embodiments, the performance difference between the first layer 1 and the second layer 2 can be various, such as strength, tear resistance, and rigidity. The strength, tear resistance, and rigidity of the second layer 2 should be better than those of the first layer 1.

[0040] Figure 3 FIG. 2 is a cross-sectional structure schematic diagram of a shaft cover according to another exemplary embodiment, as shown in Figure 3As shown, the shaft cover further comprises a mounting seat 4 arranged on the second layer 2, the mounting seat 4 is used to be connected with the folding shaft, and the mounting seat 4 is arranged in an integral manner with the second layer 2.

[0041] In the embodiment of the present disclosure, the mounting seat 4 is arranged in an integral manner with the second layer 2, without the need to use a computer numerical control (CNC) device or the like to process the mounting seat 4 on the second layer 2, thereby saving the process, reducing the cost and saving the time.

[0042] The mounting seat 4 can adopt various forms, for example, the mounting seat 4 can be a screw column, and the folding shaft is fixed with the mounting seat 4 through an additionally arranged screw; the mounting seat 4 can also be a clamping structure matched with the folding shaft, so as to fix the folding shaft with the mounting seat 4 in a clamping manner. Of course, the mounting seat 4 can also adopt other forms, as long as the folding shaft can be fixed with the shaft cover through the mounting seat 4. The shaft cover can also be provided with a structure other than the mounting seat 4 for fixing the folding shaft, which is not limited in the present disclosure.

[0043] In some embodiments, the first layer 1 at least comprises one of aluminum alloy, stainless steel and titanium alloy.

[0044] In the embodiment of the present disclosure, the aluminum alloy, the stainless steel and the titanium alloy can be relatively easily processed in various appearances, and a relatively beautiful folding terminal appearance can be obtained.

[0045] In some embodiments, the first layer 1 can be processed by a physical vapor deposition process, can also be processed by an anodization process, and can also be processed by a combination of the two methods. By using the physical vapor deposition or the anodization process, the first layer 1 can obtain a relatively beautiful appearance, and the appearance surface obtained by such processing is more wear-resistant and has good durability.

[0046] The aluminum alloy, the stainless steel and the titanium alloy material can be processed by the physical vapor deposition or the anodization process, and good appearance and wear-resistant effects can be obtained.

[0047] In some embodiments, the first layer 1 can also be made of two or more than two of the aluminum alloy, the stainless steel and the titanium alloy and the like in combination. The combination manufacturing method can be a lamination, splicing or the like, and does not involve the creation of a new material.

[0048] In some embodiments, the second layer 2 at least comprises one of carbon fiber, nickel alloy steel, low-carbon super strong steel and high-chromium high-carbon steel.

[0049] In the embodiments of the present disclosure, the second layer 2 is made of carbon fiber, nickel alloy steel and low-carbon super strong steel, which can make the second layer 2 have higher deformation resistance, thereby improving the overall rigidity and strength of the shaft cover, and further improving the protection and support of the folding shaft.

[0050] The nickel alloy steel can be 18Ni (350) martensitic age steel. The high-chromium high-carbon steel can be a steel material known as SKD11.

[0055] In some embodiments, the connecting layer 3 can exist in part between the first layer 1 and the second layer 2, or can be arranged in all areas between the first layer 1 and the second layer 2 to completely separate the first layer 1 and the second layer 2.

[0056] In some embodiments, the first layer 1 and the second layer 2 are filled with a colloid, and the colloid forms the connecting layer 3.

[0057] Using the colloid as the connecting layer 3 can make the connecting layer 3 completely adapt to the shape of the first layer 1 and the second layer 2, avoid the situation that the connecting layer 3 is not tightly attached to the first layer 1 and the second layer 2, causing the connection to be not firm, and also can effectively reduce the thickness of the connecting layer 3.

[0058] The colloid can be used in various ways, for example, the colloid is arranged on the first layer 1 or the second layer 2 in advance, then the first layer 1 and the second layer 2 are folded to make the first layer 1 and the second layer 2 adhere to each other, of course, the colloid can also be arranged on the first layer 1 and the second layer 2 at the same time; or, the first layer 1 and the second layer 2 are folded in advance, and then the colloid is injected into the gap between the first layer 1 and the second layer 2 to make the first layer 1 and the second layer 2 adhere to each other.

[0059] The glue can be in various forms, for example, the glue can be a solid glue or a liquid glue. The glue can be a glue that can solidify after taking effect, or a glue that continuously maintains viscosity and self flexibility.

[0060] In some embodiments, the glue is integrally molded with the second layer 2.

[0061] In the embodiments of the present disclosure, the glue is integrally molded with the second layer 2, without the need of injecting glue after the first layer 1 and the second layer 2 are folded, thus simplifying the process and improving the connection strength of the glue and the second layer 2.

[0062] In some embodiments, the glue can also be integrally molded with the first layer 1.

[0063] In some embodiments, the glue at least includes one of an epoxy resin and a vinyl acrylate.

[0064] In the embodiments of the present disclosure, the epoxy resin and the vinyl acrylate can effectively bond materials such as metals, and in particular, the epoxy resin can have good curing and bonding properties.

[0065] In some embodiments, the second layer 2 is made of carbon fiber material and uses an epoxy resin as the glue. The connection layer 3 made of the epoxy resin material is integrally molded with the second layer 2 made of the carbon fiber material.

[0069] The hinge cover can be arranged on the folding hinge 53 as Figure 6 shown, and the side of the second layer 2 opposite to the first layer 1 faces the folding hinge 53.

[0070] In the embodiments of the present disclosure, the hinge cover of the present embodiments is arranged on the folding hinge 53, and when the folding terminal is in the folded state, the hinge cover is exposed, and the first layer 1 of the hinge cover can provide a more beautiful and wear-resistant appearance. At the same time, when the folding terminal switches between the unfolded and folded states, the second layer 2 can provide stronger support for the folding hinge 5, thereby improving the overall structural rigidity and strength.
