Description

Technical Field

[0001] This application relates to the technical field of composite materials, and particularly to a composite material structure, a composite material laminated structure, a housing, and an electronic device. Background Art

[0002] As the terminal housing becomes thinner and thinner, the performance requirements for the applied materials are getting higher and higher. As a composite material with low density and good puncture resistance, when organic fiber is applied to the housing, it can play a role in weight reduction and improving the puncture resistance of the housing. However, the bonding force between the organic fiber and the resin is relatively low, resulting in low mechanical properties of the housing made of organic fiber alone as the applied material, and easy delamination between layers.

[0003] Currently, organic fibers and inorganic fibers are usually used in combination to enable more applications of organic fiber composite materials in the field of terminal housings. The commonly used fiber combination methods include three: Method 1 is to laminate the organic fiber and the inorganic fiber; Method 2 is to splice the organic fiber to the inorganic fiber; Method 3 is to stack the organic fiber layer and the inorganic fiber layer on top of each other. However, the above Method 1 and Method 2 are likely to affect the overall mechanical properties of the housing. The housing obtained by the above Method 3 has the same performance in each area, and cannot match the different characteristic requirements of different areas of the housing. Moreover, the amount of organic fiber used is large and the utilization rate is low, and the overall cost is relatively high. Summary of the Invention

[0004] This application provides a composite material structure, a composite material laminated structure, a housing, and an electronic device, which can obtain a housing with multiple areas. The multiple areas of the housing are mapped and corresponding to multiple devices of the electronic device, and the properties of each area are different, meeting the different characteristic requirements of different areas of the housing, and better product performance can be obtained. The following introduces this application from multiple aspects, and the implementation manners and beneficial effects of the following multiple aspects can be referred to each other.

[0005] In the first aspect of this application, a composite material structure is provided. The specific composite material structure includes: a hybrid woven fiber layer, and the hybrid woven fiber layer includes a warp fiber body distributed along the weft direction and a weft fiber body distributed along the warp direction; among the warp fiber body and the weft fiber body, at least one direction of the fiber body includes two or more types of fibers; and the warp fiber body and the weft fiber body are hybrid woven to form at least two woven areas, and the properties of the at least two woven areas are different, and the properties include one or more of interlayer bonding force, weight mechanical strength, dielectric property, density, thermal conductivity, conductivity, modulus, etc.

[0006] With the above technical solution, the embodiment of the present application mixes and weaves a warp fiber body and a weft fiber body with different types of fibers to form a mixed woven fiber layer, for example, a mixed woven fabric formed by mixing organic fibers and inorganic fibers, and at least two woven areas are formed in the mixed woven fiber layer.

[0007] It should be noted that the above-mentioned warp fiber body and weft fiber body with different types of fibers refer to that the fiber body in at least one direction (for example, the warp direction or the weft direction) (i.e., the warp fiber body or the weft fiber body) has two or more types of fibers with different fiber types (i.e., the warp fibers or weft fibers described later).

[0008] That is, the warp fiber body includes one type of warp fiber, and the weft fiber body includes two or more types of weft fibers; or,

[0009] The warp fiber body includes two or more types of warp fibers, and the weft fiber body includes one type of weft fiber; or,

[0010] The warp fiber body includes two or more types of warp fibers, and the weft fiber body includes two or more types of weft fibers.

[0011] For ease of understanding, the following takes the warp fiber body (or weft fiber body) including two types of warp fibers (or weft fibers) as an example for description.

[0012] When the two types of fibers of the warp fibers (or weft fibers) are different in fiber type, for example:

[0013] The two types of warp fibers (or weft fibers) are respectively organic fibers and inorganic fibers; or,

[0014] The two types of warp fibers (or weft fibers) are respectively inorganic fibers and organic fibers; or,

[0015] The two types of warp fibers (or weft fibers) are organic fibers of different fiber types; or,

[0016] The two types of warp fibers (or weft fibers) are inorganic fibers of different fiber types; then the material properties of the warp fiber body (or weft fiber body) with different fiber types are also different, so that the material properties of the woven area formed by mixing the warp fiber body (or weft fiber body) with different fiber types and the weft fiber body (or warp fiber body) are also different. In other words, when the fiber types of the fibers in at least two woven areas are different, the material properties of each woven area are also different. That is, the properties of at least two woven areas are different, and the properties include one or more of interlayer bonding force, mechanical strength, dielectric properties, density, thermal conductivity, conductivity, modulus, etc.

[0017] Thus, the composite material structure of the embodiments of the present application can form a hybrid woven fiber layer with different performances in different regions to meet the different requirements of different regions of a product (such as a housing), and obtain better product performance.

[0018] In addition, the warp fibers and weft fibers in the hybrid woven fiber layer of the embodiments of the present application are hybrid woven to form woven regions with different material performances. That is, between different woven regions, they are all connected by continuous warp fibers and weft fibers, and the fibers between each woven region are continuous and unbroken. Therefore, the overall mechanical performance of the composite material structure of the embodiments of the present application is better.

[0019] In a possible implementation of the above first aspect, when at least one woven region is assembled with an electronic device, at least one of the at least one woven region corresponds to different components of the electronic device in a mapped manner.

[0020] By adopting the above technical solution, at least one of at least two woven regions of the embodiments of the present application corresponds to different components of the electronic device in a mapped manner. Exemplarily, the mutual mapping correspondence relationship between at least one woven region of the hybrid woven fiber layer of the embodiments of the present application and different components of the electronic device is that: the size and relative position of the woven region have a mapped correspondence relationship with the size and relative position of the component of the electronic device. For example, the woven region (such as the first woven region described later) covers the component of the electronic device (such as the battery described later).

[0021] In a possible implementation of the above first aspect, the composite material structure is used for the back cover of an electronic device.

[0022] In a possible implementation of the above first aspect, at least one type of fiber among two or more types of fibers is continuously distributed in a set width along the corresponding direction; and / or, at least two types of fibers among two or more types of fibers are alternately distributed in a set width along the corresponding direction.

[0023] By adopting the above technical solution, in the fiber body (such as a warp fiber body or a weft fiber body) having two or more types of fibers of the embodiments of the present application, it is possible that at least one type of fiber is continuously distributed in a set width along the corresponding direction (i.e., the warp direction or the weft direction).

[0024] That is, the warp fiber body includes one type of warp fiber, the weft fiber body includes two or more types of weft fibers, and at least one of the two or more types of weft fibers is continuously distributed in a set width along the warp direction.

[0025] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes one type of weft fiber, and at least one of the more than two types of warp fibers is continuously distributed along the weft direction with a set width.

[0026] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, and at least one of the more than two types of warp fibers is continuously distributed along the weft direction with a set width.

[0027] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, and at least one of the more than two types of weft fibers is continuously distributed along the warp direction with a set width.

[0028] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, at least one of the more than two types of warp fibers is continuously distributed along the weft direction with a set width, and at least one of the more than two types of weft fibers is continuously distributed along the warp direction with a set width.

[0029] However, not limited thereto, in the fiber body having more than two types of fibers (such as the warp fiber body or the weft fiber body) in the embodiments of the present application, at least two types of fibers among the more than two types of fibers (i.e., warp fibers or weft fibers) may be alternately distributed along the corresponding direction (i.e., the warp direction or the weft direction) with a set width.

[0030] That is, the warp fiber body includes one type of warp fiber, the weft fiber body includes more than two types of weft fibers, and at least two types of the more than two types of weft fibers are alternately distributed along the warp direction with a set width.

[0031] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes one type of weft fiber, and at least two types of the more than two types of warp fibers are alternately distributed along the weft direction with a set width.

[0032] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, and at least two types of the more than two types of warp fibers are alternately distributed along the weft direction with a set width.

[0033] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, and at least two types of the more than two types of weft fibers are alternately distributed along the warp direction with a set width.

[0034] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, at least two types of the more than two types of warp fibers are alternately distributed along the weft direction with a set width, and at least two types of the more than two types of weft fibers are alternately distributed along the warp direction with a set width.

[0035] Moreover, in the fiber body having more than two types of fibers (such as a warp fiber body or a weft fiber body) according to the embodiments of the present application, it is also possible that at least one type of fiber is continuously distributed along the corresponding direction (i.e., the warp direction or the weft direction) with a set width, and at least two types of fibers are alternately distributed along the corresponding direction with a set width.

[0036] That is, the warp fiber body includes one type of warp fiber, the weft fiber body includes more than two types of weft fibers, at least one of the more than two types of weft fibers is continuously distributed along the warp direction with a set width, and at least two weft fibers are alternately distributed along the warp direction with a set width.

[0037] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes one type of weft fiber, at least one of the more than two types of warp fibers is continuously distributed along the weft direction with a set width, and at least two warp fibers are alternately distributed along the weft direction with a set width.

[0038] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, at least one of the more than two types of warp fibers is continuously distributed along the weft direction with a set width, and at least two warp fibers are alternately distributed along the weft direction with a set width.

[0039] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, at least one of the more than two types of weft fibers is continuously distributed along the warp direction with a set width, and at least two weft fibers are alternately distributed along the warp direction with a set width.

[0040] Alternatively, in some possible implementations, the warp fiber body includes more than two types of warp fibers, the weft fiber body includes more than two types of weft fibers, at least one of the more than two types of warp fibers is continuously distributed along the weft direction with a set width, and at least two warp fibers are alternately distributed along the weft direction with a set width, and at least one of the more than two types of weft fibers is continuously distributed along the warp direction with a set width, and at least two weft fibers are alternately distributed along the warp direction with a set width.

[0041] Exemplarily, in a warp fiber body having two or more types of fibers, at least two types of fibers are alternately distributed along the weft direction for a certain width, or in a weft fiber body having two or more types of fibers, at least two types of fibers are alternately distributed along the warp direction for a certain width.

[0042] Wherein, the ratio range of the above-mentioned certain width to the width of the entire direction includes (0, 1].

[0043] That is, in a warp fiber body having two or more types of fibers, at least two types of fibers are alternately distributed across the entire width of the weft direction (i.e., the ratio of the certain width to the width of the entire direction is 1), or at least two types of fibers are alternately distributed across a partial width of the entire weft direction (i.e., the ratio of the certain width to the width of the entire direction is any value between 0 and 1);

[0044] Or, in a weft fiber body having two or more types of fibers, at least two types of fibers are alternately distributed across the entire width of the warp direction (i.e., the ratio of the certain width to the width of the entire direction is 1), or at least two types of fibers are alternately distributed across a partial width of the entire warp direction (i.e., the ratio of the certain width to the width of the entire direction is any value between 0 and 1).

[0045] In addition, the number of types of fibers for the alternate distribution in the embodiments of the present application is not limited, and two or more (for example, three, four, five or more) types of fibers can be alternately distributed.

[0046] It should be noted that the above-mentioned continuously distributed set width means that: in the mixed woven fiber layer, along the weft direction, within the set width range, there are multiple warp fibers of the same type continuously distributed, and the fiber types of any two adjacent warp fibers are the same. Along the warp direction, within the set width range, there are multiple weft fibers of the same type continuously distributed, and the fiber types of any two adjacent weft fibers are the same. That is, in the mixed woven fiber layer of the embodiments of the present application, only warp fibers (or weft fibers) of the same type are continuously distributed within the set width. The above-mentioned alternate distribution for a certain width means that: in the mixed woven fiber layer, along the weft direction, within a certain width range, multiple warp fibers of different types are alternately distributed. Along the warp direction, within a certain width range, multiple weft fibers of different types are alternately distributed. That is, in the mixed woven fiber layer of the embodiments of the present application, two or more types of warp fibers (or weft fibers) are alternately distributed within a certain width.

[0047] In a possible implementation of the above first aspect, the warp fiber body includes more than two types of warp fibers, and the warp fibers extend along the warp direction. The weft fiber body includes more than two types of weft fibers, and the weft fibers extend along the weft direction. More than two types of warp fibers and more than two types of weft fibers are mixed and woven to form at least two weaving regions. Among them, at least two weaving regions are mapped and corresponding to a plurality of external devices.

[0048] By adopting the above technical solution, at least two weaving regions are formed in the mixed woven fiber layer in the embodiment of the present application. Since the fiber types of the fibers in at least two weaving regions are different, the properties of at least two weaving regions are also different. Therefore, at least two weaving regions with different material properties in the mixed woven fiber layer can be mapped and corresponding to a plurality of external devices (such as a plurality of devices of an electronic device described later), so that the properties of each region of the composite material structure are different, and better material properties can be obtained.

[0049] In a possible implementation of the above first aspect, the warp fiber body includes two types of warp fibers, and the weft fiber body includes two types of weft fibers. The fiber types of the two types of warp fibers are the same as the fiber types of the two types of weft fibers. And the two types of warp fibers are continuously distributed along the weft direction with a set width respectively, and the two types of weft fibers are continuously distributed along the warp direction with a set width respectively. The fiber types of the fibers in any two adjacent set widths are different.

[0050] It should be noted that the fact that the fiber types of the fibers in any two adjacent set widths are different means that in the warp fiber body (or the weft fiber body), one type of warp fiber (or weft fiber) continuously distributed with a set width and another type of warp fiber (or weft fiber) continuously distributed with a set width are alternately distributed along the warp direction (or the weft direction).

[0051] In a possible implementation of the above first aspect, the mixed woven fiber layer includes a first weaving region, a second weaving region, and a third weaving region. The first weaving region includes a plurality of first warp fibers and a plurality of first weft fibers that are mixed and woven. The second weaving region includes a plurality of second warp fibers and a plurality of second weft fibers that are mixed and woven. The third weaving region includes a plurality of third warp fibers and a plurality of third weft fibers that are mixed and woven. Among them, the fiber types of the first warp fibers and the first weft fibers are the same, and the fiber types of the third warp fibers and the third weft fibers are the same. The fiber type of the first warp fiber is different from the fiber type of the second warp fiber, and the fiber type of the third warp fiber is the same as the fiber type of the second warp fiber. Or, the fiber type of the first weft fiber is different from the fiber type of the second weft fiber, and the fiber type of the third weft fiber is the same as the fiber type of the second weft fiber.

[0052] With the above technical solution, in the hybrid woven fiber layer of the embodiment of the present application, a plurality of woven regions with different material properties are formed (such as the above-mentioned first woven region, second woven region, and third woven region), so that there are differences in material properties between the regions of the composite material structure, and finally a product (such as the housing described later) with different performances in each region (such as the key region and non-key region corresponding to multiple devices of the electronic device described later) can be obtained.

[0053] In a possible implementation of the above first aspect, the first woven region is mapped and corresponding to the device of the electronic device, the second woven region is mapped and corresponding to the peripheral region of the device, the peripheral region surrounds the device, and the third woven region is mapped and corresponding to the region adjacent to the peripheral region; the device includes one or more of a battery, a radio frequency device, a radio frequency device sensitive to dielectric properties, a main board, and a sub-board.

[0054] In a possible implementation of the above first aspect, the fiber types of the warp fiber body include organic fibers and / or inorganic fibers; and / or, the fiber types of the weft fiber body include organic fibers and / or inorganic fibers.

[0055] In a possible implementation of the above first aspect, the organic fibers include ultra-high molecular weight polyethylene fibers, aramid fibers, polyimide fibers, PBO fibers, LCP fibers, PET fibers, flax fibers, or cellulose fibers.

[0056] In a possible implementation of the above first aspect, the inorganic fibers include glass fibers, quartz fibers, ceramic fibers, carbon fibers, or basalt fibers.

[0057] In a possible implementation of the above first aspect, the composite material structure further includes a resin matrix, and the hybrid woven fiber layer is located inside the resin matrix.

[0058] The second aspect of the present application provides a composite material laminated structure, and the composite material laminated structure is prepared by using any one of the composite material structures in the possible implementations of the above first aspect.

[0059] In a possible implementation of the above second aspect, the number of the composite material structures includes a plurality, and the plurality of composite material structures are stacked.

[0060] With the above technical solution, the composite material laminated structure of the embodiment of the present application not only uses the composite material structure as the core layer, but also uses the composite material structure as the surface layer, so as to obtain a composite material laminated structure having a position and size corresponding relationship with the application product (such as an electronic device).

[0061] In a possible implementation of the second aspect described above, along the stacking direction, the projections of the first braided regions of each layer of the composite material structure coincide, and the fiber types of the first warp fibers and the first weft fibers in the first braided region both include organic fibers.

[0062] By adopting the above technical solution, in the embodiment of the present application, the projections of the first braided regions are made to coincide to enhance the material properties of the corresponding regions of the first braided regions (for example, the key regions of the housing described later).

[0063] It should be noted that multiple braided regions in the embodiment of the present application can all correspond to the key regions of the housing. For example, it can also be that the second braided region corresponds to the key region of the housing; or, the third braided region corresponds to the key region of the housing; or, both the first braided region and the second braided region correspond to the key region of the housing; or, both the second braided region and the third braided region correspond to the key region of the housing; or, the first braided region, the second braided region, and the third braided region all correspond to the key region of the housing, etc.

[0064] In a possible implementation of the second aspect described above, along the stacking direction, the projections of the first braided regions of at least two layers of the composite material structure do not coincide, and the fiber types of the first warp fibers and the first weft fibers in the first braided region both include organic fibers.

[0065] By adopting the above technical solution, in the embodiment of the present application, the projections of the first braided regions are made not to coincide to perform specific staggered laminations according to actual requirements, so as to obtain better comprehensive performance.

[0066] In a possible implementation of the second aspect described above, the fiber types of the fibers of any two adjacent layers of the composite material structure are different from each other.

[0067] In a possible implementation of the second aspect described above, the composite material laminated structure further includes a single braided fiber layer. The single braided fiber layer includes multiple single fibers that are braided with each other, and the fiber types of the multiple single fibers are the same; the single braided fiber layer is laminated on both sides opposite to the mixed braided fiber layer.

[0068] By adopting the above technical solution, in the embodiment of the present application, the single braided fiber layer is used as the surface layer and the mixed braided fiber layer is used as the core layer to jointly form the composite material laminated structure. It should be noted that the embodiment of the present application does not specifically limit the above composite material laminated structure. According to actual application needs, the composite material laminated structure can also be a structure with the mixed braided fiber layer as the surface layer and the single braided fiber layer as the core layer, or a multi-layer structure with the mixed braided fiber layer and the single braided fiber layer laminated with each other, that is, the number of the mixed braided fiber layer and the single braided fiber layer is not limited to the three layers mentioned above. For example, it can also be four layers, five layers, or even more layers.

[0069] It should be noted that in the embodiments of the present application, there is no specific limitation on the structure of the fiber layer laminated with the hybrid woven fiber layer in the composite material laminated structure, as long as at least one hybrid woven fiber layer is included in the composite material laminated structure. For example, it may also be a fiber layer in which the weaving area does not have a mapping correspondence with the devices of the electronic device, and the fiber layer is woven from more than two types of fibers.

[0070] In a possible implementation of the second aspect above, the fiber type of the single fiber includes inorganic fibers.

[0071] The third aspect of the present application provides a housing, which is prepared from the composite material laminated structure of any one of the possible implementations of the second aspect above.

[0072] In a possible implementation of the third aspect above, the housing includes a key area, a side area, and a corner area; wherein, the side area surrounds the key area, and the corner area is adjacent to the side area; the first weaving area of the hybrid woven fiber layer covers the key area, the second weaving area of the hybrid woven fiber layer covers the side area, and the third weaving area of the hybrid woven fiber layer covers the corner area.

[0073] Exemplarily, the housing has a key area (such as the battery area of the battery cover) corresponding to the above-mentioned multiple devices (such as the battery or radio frequency device described later), and a non-key area (i.e., the side area and the corner area, such as the periphery and the four corners of the battery cover) corresponding to another part of the devices of the electronic device.

[0074] The fourth aspect of the present application provides an electronic device, which includes a housing of any one of the possible implementations of the third aspect above; and multiple devices, and the housing includes multiple areas that are mapped and correspondingly covered with the multiple devices.

[0075] The multiple areas of the housing include a key area (such as the battery area of the battery cover) corresponding to the above-mentioned multiple devices (such as the battery or radio frequency device described later), and a non-key area (such as the periphery or the four corners of the battery cover) corresponding to another part of the devices of the electronic device.

[0076] In a possible implementation of the fourth aspect above, the devices include one or more of a battery, a radio frequency device, a radio frequency device sensitive to dielectric properties, a main board, and a sub-board.

[0077] In a possible implementation of the fourth aspect above, the multiple areas include multiple first weaving areas, multiple second weaving areas, and multiple third weaving areas of the hybrid woven fiber layer; the multiple first weaving areas cover each device, the multiple second weaving areas cover the peripheral areas of each device, and the multiple third weaving areas are adjacent to the multiple second weaving areas.

[0078] With the above technical solution, in the embodiment of the present application, a prepreg of a composite material structure (such as the above-mentioned hybrid woven fiber layer) having a positional and dimensional correspondence relationship with an application product (such as an electronic device) (for example, a plurality of first woven areas correspond to key areas of the housing and cover a plurality of devices of the electronic device, and a plurality of second woven areas and third woven areas both correspond to non-key areas of the housing and cover the peripheral areas of the plurality of devices and the four corner areas of the electronic device) is laminated, so that the fiber types in each area of the composite material structure are different, that is, the materials are different, thereby obtaining a composite material structure with different material properties in each area, and further obtaining a final product that meets different performance requirements in different areas, such as the housing in the embodiment of the present application.

[0079] In a possible implementation of the above fourth aspect, the device includes a battery. The first warp fibers and the first weft fibers in the first woven area both include ultra-high molecular weight polyethylene fibers. The second warp fibers in the second woven area include ultra-high molecular weight polyethylene fibers, and the second weft fibers include glass fibers, or the second warp fibers include glass fibers and the second weft fibers include ultra-high molecular weight polyethylene fibers. The third warp fibers and the third weft fibers in the third woven area both include glass fibers. The second woven area is located in the peripheral area of the housing, and the third woven area is located in the corner area of the housing.

[0080] With the above technical solution, the key area of the housing in the embodiment of the present application, for example, the area corresponding to the battery in the electronic device, is woven with organic fibers (such as ultra-high molecular weight polyethylene fibers) to obtain better safety protection. The four corner areas of the housing are woven with inorganic fibers (such as glass fibers) to obtain better interlayer bonding force. The four side areas of the housing are woven with a mixture of organic fibers and inorganic fibers. The presence of inorganic fibers improves the interlayer bonding force of each layer, thereby improving the overall stiffness of the housing. At the same time, the mixed use of organic fibers and inorganic fibers can reduce the usage amount of organic fibers, improve the utilization rate of organic fibers, and significantly reduce the raw material cost.

[0081] In a possible implementation of the above fourth aspect, the device includes a radio frequency device. The first warp fibers and the first weft fibers in the first woven area both include glass fibers. The second warp fibers in the second woven area include carbon fibers, and the second weft fibers include glass fibers, or the second warp fibers include glass fibers and the second weft fibers include carbon fibers. The third warp fibers and the third weft fibers in the third woven area both include carbon fibers.

[0082] With the above technical solution, the key area of the housing in the embodiment of the present application, for example, the area corresponding to the radio frequency device in the electronic device, is woven with inorganic fibers (such as glass fibers) to not shield the radio frequency device and achieve the non-shielding function. For the four corner areas and the four side areas of the housing, they are woven with a mixture of inorganic fibers (such as glass fibers) and organic fibers (such as carbon fibers), which can utilize the high strength and high rigidity of the carbon fibers to improve the overall stiffness of the housing.

[0083] In a possible implementation of the above fourth aspect, the device includes a dielectric property sensitive radio frequency device. The first warp fibers and the first weft fibers in the first weaving area both include quartz fibers. The second warp fibers in the second weaving area include quartz fibers and the second weft fibers include glass fibers, or the second warp fibers include glass fibers and the second weft fibers include quartz fibers. The third warp fibers and the third weft fibers in the third weaving area both include glass fibers.

[0084] With the above technical solution, the key area of the housing in the embodiment of the present application, for example, the area corresponding to the dielectric property sensitive radio frequency device in the electronic device, is woven with inorganic fibers (such as quartz fibers). The quartz fibers have a low dielectric loss, which can avoid adverse effects on the dielectric property sensitive radio frequency device. For the four corner areas and the four side areas of the housing, they are woven with a mixture of inorganic fibers (such as glass fibers) and inorganic fibers (such as quartz fibers), which can reduce the usage amount of quartz fibers, improve the utilization rate of quartz fibers, and significantly reduce the raw material cost.

[0112] An embodiment of the present application provides a housing including a composite material structure, wherein the composite material structure is formed by hybrid weaving a warp fiber body and a weft fiber body (for example, organic fibers and inorganic fibers) to form at least two weaving regions, and the at least two weaving regions have different fiber types and corresponding different properties, and the properties include one or more of interlayer bonding force, mechanical strength, dielectric property, density, thermal conductivity, conductivity, modulus, etc. Thus, the composite material structure can meet the different characteristic requirements of different regions of the housing to obtain a housing with different performances in each region.

[0113] The housing provided by the embodiment of the present application is applied to an electronic device. The electronic devices involved in the embodiment of the present application may be, for example: mobile phones, tablet computers, e-readers, remote controls, personal computers (PCs), laptops, personal digital assistants (PDAs), in-vehicle devices, Internet TVs, wearable devices, televisions and other electronic devices.

[0114] The embodiment of the present application does not make any special restrictions on the specific form of the above-mentioned electronic device. For the convenience of description below, the electronic device is taken as an example of a mobile phone.

[0115] Refer to Figure 1 , the above-mentioned electronic device 1 mainly includes: a display module 10, a middle frame 11, and a rear cover (or called a rear shell) 12. The middle frame 11 is located between the display module 10 and the rear cover 12.

[0116] The display module 10, the middle frame 11, and the rear cover 12 can be respectively disposed on different layers in the thickness direction of the electronic device 1. These layers can be parallel to each other, and the plane where each layer is located can be called the X-Y plane, and the direction perpendicular to the X-Y plane can be called the Z direction (i.e., the thickness direction). In other words, the display module 10, the middle frame 11, and the rear cover 12 can be distributed in layers in the Z direction.

[0117] The display module 10 is used to display images. The display module 10 can pass through the middle frame 11 through a flexible printed circuit (FPC) 101 as shown in Figure 1 the figure and be electrically connected to a printed circuit board (PCB) 111 disposed on the middle frame 11. Thus, the printed circuit board (PCB) 111 can transmit display data to the display module 10 to control the display module 10 to display images.

[0118] The middle frame 11 is located between the display module 10 and the rear cover 12. The surface of the middle frame 11 away from the display module 10 is used to mount internal components such as a printed circuit board (PCB) 111, a battery 112, a camera, an antenna, a main board, and radio frequency devices (not shown in the figure).

[0119] The rear cover 12 is mounted on the middle frame 11. After the rear cover 12 is closed with the middle frame 11, the above internal components are located between the rear cover 12 and the middle frame 11, and the rear cover 12 can protect the internal components of the above electronic device 1.

[0120] With the development of technology, electronic devices are widely used, and the housing of electronic devices (such as the above rear cover 12) is getting thinner and thinner, and the requirements for the modulus and puncture resistance of the application materials of the housing are getting higher and higher.

[0121] It can be understood that different components in the electronic device 1 (such as the above internal components) correspond to different regions of the housing (such as the above rear cover 12). Moreover, different components have different performance requirements for the corresponding different regions, which requires the application materials of the housing to be able to meet different characteristic requirements of different regions. Exemplarily, the components of the electronic device include one or more of a battery 112, radio frequency devices, dielectric property-sensitive radio frequency devices, a main board, and a daughter board.

[0122] Exemplarily, according to the different performance requirements of the device, the housing can be divided into a key area and a non-key area (where the non-key area includes the edge area and the corner area). Among them, some devices of the electronic device (such as the above-mentioned battery 112 or radio frequency device, etc.) correspond to the key area of the housing (such as the battery area of the battery cover, etc.) to require better protection ability, and another part of the devices corresponds to the non-key area (that is, the above-mentioned edge area and corner area, such as the periphery or the four corners of the battery cover) to require better bonding force with the resin.

[0123] In some possible implementation manners, in order to meet the mechanical property requirements of the housing, it is usually achieved by combining organic fibers and inorganic fibers.

[0124] Generally, there are two methods to realize the combined use of organic fibers and inorganic fibers: The first method is to use inorganic fibers as the main material, and organic fibers as the reinforcing material in local areas; the second method is to stack organic fibers and inorganic fibers as a complete layer and then form and cure them together.

[0125] The implementation manners of the above two technologies will be further described in detail below with reference to the accompanying drawings.

[0126] Reference Figure 2 , Figure 2 shows a schematic structural diagram of a housing 2'. Among them, the housing 2' includes an inorganic fiber layer 201', an organic fiber layer 202' and a surface treatment layer 203'. In order to improve the mechanical properties of the housing 2', reinforcement is usually carried out in the local area of the housing 2' (that is, the above-mentioned key area, such as the battery area of the battery cover).

[0127] Specifically, as Figure 2 shown, a groove 2011' is provided at a position corresponding to the key area of the housing 2' in the inorganic fiber layer 201', and the organic fiber layer 202' is arranged in the groove 2011' by fitting or splicing, and the surface treatment layer 203' is stacked on the inorganic fiber layer 201', and is located on the side of the inorganic fiber layer 201' away from the organic fiber layer 202'. Exemplarily, the fiber type of the inorganic fiber layer 201' includes glass fiber.

[0128] Thus, the housing 2' uses the inorganic fiber layer 201' as the main material, and the key area of the housing 2' (such as the battery area of the above-mentioned battery cover, as Figure 2The middle groove (shown in the area of 2011’) is reinforced by the organic fiber layer 202’ to improve the protection ability of this key area. The circumferential edges of the organic fiber layer 202’ in the housing 2’ (i.e., the above-mentioned non-critical areas) are all conventional inorganic fibers, so that the processing scheme of the housing 2’ can still adopt the processing scheme of conventional inorganic fibers. For example, the housing 2’ is processed by a Computer Numerical Control (CNC) machine tool.

[0129] Exemplarily, the organic fiber layer 202’ can adopt the scheme of first being formed separately and then being attached to the groove 2011’ of the inorganic fiber layer 201’ (Scheme 1). However, when adopting the attachment forming scheme (i.e., Scheme 1), since the adhesive film or glue used for attachment between the organic fiber layer 202’ and the inorganic fiber layer 201’ has a certain thickness, it will cause an increase in the overall thickness of the housing 2’.

[0130] Or, exemplarily, it is also possible to adopt the scheme of first splicing the organic fiber layer 202’ with the inorganic fiber layer 201’ and then forming them together (Scheme 2). However, when adopting the splicing forming scheme (i.e., Scheme 2), due to the splicing gap between the organic fiber layer 202’ and the inorganic fiber layer 201’, the appearance surface effect of the housing 2’ is not good, and a thicker coating is often required to cover the splicing marks, which affects the production yield of the housing 2’.

[0131] Moreover, the inner surface in contact between the organic fiber layer 202’ and the inorganic fiber layer 201’ of the above Method 1 is discontinuous, that is, the organic fibers and inorganic fibers between the organic fiber layer 202’ and the inorganic fiber layer 201’ of Method 1 are separated and discontinuous, which makes the overall mechanical properties of the housing 2’ prepared by Method 1 decline.

[0132] Reference Figure 3 , Figure 3 shows a schematic structural diagram of another housing 2”. Among them, the housing 2” includes an inorganic fiber layer 201”, an organic fiber layer 202” and a surface treatment layer 203”.

[0133] Specifically, as Figure 3 shown, along the stacking direction (i.e., the thickness direction of the housing 2”, as shown by the Z direction in Figure 3 ), the inorganic fiber layer 201” is stacked on both sides of the organic fiber layer 202” opposite to each other, and the surface treatment layer 203” is stacked on the inorganic fiber layer 201” and is located on the side of the inorganic fiber layer 201” away from the organic fiber layer 202”. That is, the stacking structure of the inorganic fiber layer 201”, the organic fiber layer 202” and the surface treatment layer 203” in the housing 2” is a structure similar to a sandwich.

[0134] Exemplarily, as Figure 3As shown, the laminated structure of the housing 2" can be an inorganic fiber layer 201" as the skin layer and an organic fiber layer 202" as the core layer; however, it is not limited to this. According to actual application requirements, the laminated structure of the housing 2" can also be an organic fiber layer 202" as the skin layer and an inorganic fiber layer 201" as the core layer, or a multi-layer structure with alternating lamination of the inorganic fiber layer 201" and the organic fiber layer 202", that is, the number of the inorganic fiber layer 201" and the organic fiber layer 202" is not limited to Figure 3 the three layers in Figure 3 . For example, it can also be four layers, five layers or even more layers.

[0135] Thus, the comprehensive performance of the housing 2" is realized by laminating the organic fiber layer 202" and the inorganic fiber layer 201" together. The process is simple, and the inner surfaces of each organic fiber layer 202" and inorganic fiber layer 201" are continuous, and the overall mechanical properties of the housing 2" are kept intact. It should be noted that under the above laminated structure, since the housing 2" uses a complete layer of organic fiber, using traditional CNC to process the housing 2" easily causes the organic fiber to produce fuzz. Therefore, the processing scheme of the housing 2" mostly adopts processing methods such as laser or punching for shape processing.

[0136] However, each layer of the laminated structure of the above method two is made of a single organic fiber or inorganic fiber, and the single material results in a single material property in each region of each layer. That is, the material properties of each region of the housing 2" obtained by method two are the same, and it is impossible to match the different material property requirements of different devices (such as the above battery 112, etc.) in the electronic device 1 for the key regions (such as the battery region of the battery cover above) and non-key regions (such as the periphery or the four corners of the battery cover above) of the housing 2".

[0137] In addition, the organic fiber material covers the entire organic fiber layer 202", which includes both the key regions and the non-key regions of the housing 2". The usage amount of the organic fiber material is large and the utilization rate is low, increasing the preparation cost of the housing 2". During the process of processing the housing 2", the processing edges of the organic fiber covering the entire organic fiber layer 202" will be exposed, and there is a risk of interfacial peeling.

[0138] In order to match the different material property requirements of different devices of the electronic device for the corresponding different regions of the housing and obtain a structural member with different performances in each region.

[0139] An embodiment of the present application provides a housing including a composite material structure. The housing is applied to the above-mentioned electronic device. The housing includes a plurality of regions, and the plurality of regions of the housing are formed by hybrid weaving of warp fibers and weft fibers. The performance of each region of the housing is different, and the plurality of regions are mapped and corresponding to cover a plurality of components of the electronic device, meeting the different performance requirements of different regions of the housing, and better product performance can be obtained.

[0140] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0141] Reference Figure 4a and Figure 4b , wherein the housing 2 includes a composite material structure 201, a single woven fiber layer 202, and a surface treatment layer 203.

[0142] Specifically, as Figure 4a shown, along the stacking direction (i.e., the thickness direction of the housing 2, as shown by the Z direction in Figure 4a ), the single woven fiber layer 202 is stacked on both opposite sides of the composite material structure 201, and the surface treatment layer 203 is stacked on the single woven fiber layer 202 and is located on the side of the single woven fiber layer 202 away from the composite material structure 201.

[0143] Exemplarily, as Figure 4b shown, in the housing 2, the single woven fiber layer 202 serves as the surface layer, and the composite material structure 201 serves as the core layer, jointly forming a composite laminate structure similar to a sandwich. However, it is not limited thereto. According to actual application requirements, the composite laminate structure of the housing 2 may also be a structure in which the composite material structure 201 serves as the surface layer and the single woven fiber layer 202 serves as the core layer, or a multi-layer structure in which the composite material structure 201 and the single woven fiber layer 202 are stacked, that is, the number of the composite material structure 201 and the single woven fiber layer 202 is not limited to Figure 4b three layers in

[0144] Reference Figure 4a and Figure 4b shows that the difference between the housing 2 in the embodiment of the present application and the Figure 3 shown housing 2” is that the housing 2 uses the composite material structure 201 as the core layer.

[0145] The structure and working principle of the composite material structure 201 in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0146] Reference Figure 5 , Figure 5The schematic diagram of a composite material structure 201 provided by an embodiment of the present application is shown. Among them, the composite material structure 201 includes a hybrid woven fiber layer 3, and the hybrid woven fiber layer 3 includes a warp fiber body 311 and a weft fiber body 312. The warp fiber body 311 includes warp fibers extending along the warp direction (such as Figure 5 shown by the S direction in Figure 5 ), and the weft fiber body 312 includes weft fibers extending along the weft direction (such as

[0147] shown by the W direction in Figure 5 ). Specifically, as Figure 5 shown, the warp fiber body 311 includes two types of warp fibers, namely organic fibers (such as Figure 5 shown by U in Figure 5 ) and inorganic fibers (such as Figure 5 shown by E in

[0148] ). The weft fiber body 312 includes two types of weft fibers, namely organic fibers (such as Figure 5 shown by U in

[0149] ) and inorganic fibers (such as Figure 5 shown by E in Figure 6 ), and the organic fiber U of the warp fiber body 311 and the organic fiber U of the weft fiber body 312 have the same fiber type, and the inorganic fiber E of the warp fiber body 311 and the inorganic fiber E of the weft fiber body 312 have the same fiber type. Figure 6 Exemplarily, as Figure 5 shown, the organic fiber U in the embodiment of the present application is ultra-high molecular weight polyethylene fiber, and the inorganic fiber E is glass fiber. However, the types of organic fibers and inorganic fibers in the embodiments of the present application are not specifically limited, as long as they can meet the performance requirements of the final product (i.e., the above-mentioned housing 2). For example, the inorganic fibers in the embodiments of the present application may further include quartz fibers, ceramic fibers, carbon fibers or basalt fibers, and the organic fibers may further include aramid fibers, polyimide fibers, PBO fibers, LCP fibers, PET fibers, flax fibers or cellulose fibers.

[0150] Continuing to refer to Figure 6As shown, along the weft direction W, the inorganic fibers E are continuously distributed with a set width a, and the organic fibers U are continuously distributed with a set width b. Along the warp direction S, the inorganic fibers E are continuously distributed with a set width c, and the organic fibers U are continuously distributed with a set width d. Among them, each warp fiber 3111 extending along the warp direction S (for example, an inorganic fiber E or an organic fiber U) is respectively interwoven with each weft fiber 3121 extending along the weft direction W (for example, an inorganic fiber E or an organic fiber U) to form a hybrid woven fiber layer 3 of the embodiment of the present application by hybrid weaving, and the hybrid woven fiber layer 3 of the embodiment of the present application has a plurality of weaving regions 32. Exemplarily, the composite material structure 201 further includes a resin matrix (not shown in the figure), and the hybrid woven fiber layer 3 is located inside the resin matrix.

[0151] It should be noted that the continuously distributed set width in the embodiment of the present application refers to: in the hybrid woven fiber layer 3, along the weft direction W, within the set width range, there are multiple warp fibers 3111 of the same type continuously distributed; along the warp direction S, within the set width range, there are multiple weft fibers 3121 of the same type continuously distributed.

[0152] For example, as Figure 6 shown, in the hybrid woven fiber layer 3 of the embodiment of the present application, only the same type of warp fibers 3111 (i.e., inorganic fibers E) are continuously distributed within the set width a; within the set width c, only the same type of weft fibers 3121 (i.e., inorganic fibers E) are continuously distributed, within the set width b, only the same type of warp fibers 3111 (i.e., organic fibers U) are continuously distributed, and within the set width d, only the same type of weft fibers 3121 (i.e., organic fibers U) are continuously distributed.

[0153] It should be noted that the embodiment of the present application does not specifically limit the way of continuously distributing the set width of the warp fibers and the weft fibers, as long as at least one direction (for example, the warp direction S or the weft direction W) in the warp direction S and the weft direction W has at least two types of fibers (for example, the above-mentioned inorganic fibers E and organic fibers U), and at least one type of fiber (for example, the above-mentioned inorganic fibers E or organic fibers U) is continuously distributed with a set width.

[0154] For example, when the inorganic fibers E (or organic fibers U) of the weft fiber body with two or more types of fibers (for example, inorganic fibers E and organic fibers U) are continuously distributed with a set width along the warp direction S, the warp fibers of the warp fiber body can be a type of fiber (for example, inorganic fibers E or organic fibers U) continuously distributed throughout the weft direction W; or,

[0155] it can also be two or more types of fibers (for example, inorganic fibers E and organic fibers U) alternately distributed with a set width along the weft direction W; or,

[0156] It may also be that two or more types of fibers (for example, inorganic fiber E and organic fiber U) are continuously distributed along the weft direction W with a set width;

[0157] It may also be that at least one of two or more types of fibers (for example, inorganic fiber E and organic fiber U) (for example, inorganic fiber E or organic fiber U) is continuously distributed along the weft direction W with a set width.

[0158] That is, when the fibrous body in one direction (i.e., the warp direction S or the weft direction W) of the embodiment of the present application has two or more types of fibers (for example, the above-mentioned inorganic fiber E and organic fiber U), when at least one type of fiber (for example, the above-mentioned inorganic fiber E or organic fiber U) among the two or more types of fibers (for example, the above-mentioned inorganic fiber E and organic fiber U) is continuously distributed with a set width, the distribution of the fibers in the other direction (i.e., the weft direction W or the warp direction S) is not limited.

[0159] Continue to refer to Figure 5 and in combination with Figure 6 , the inorganic fiber E and the organic fiber U form a plurality of weaving regions 32 (as shown by the grid in Figure 5 and the dotted box in Figure 6 ). The plurality of weaving regions 32 include a plurality of first weaving regions 321 (as shown by the U / U regions in Figure 5 and Figure 6 ), a plurality of second weaving regions 322 (as shown by the E / U regions and U / E regions in Figure 5 and Figure 6 ), and a plurality of third weaving regions 323 (as shown by the E / E regions in Figure 5 and Figure 6 ). Figure 6 Shows Figure 5 a partial enlarged schematic view of four weaving regions 32 in the lower left corner of

[0160] . It should be noted that in the embodiment of the present application, the naming method for the weaving region is "warp fiber / weft fiber". Figure 6 Specifically, as shown in Figure 6 , the first weaving region 321 (as shown by the U / U region in the upper right corner in

[0161] ) includes organic fiber U (i.e., the first warp fiber 3211) continuously distributed with a set width b and organic fiber U (i.e., the first weft fiber 3212) continuously distributed with a set width d. That is, the first weaving region 321 is formed by mixing and weaving organic fiber U (for example, the above-mentioned ultra-high molecular weight polyethylene fiber) along the warp direction S and the weft direction W respectively. Exemplarily, the first weaving region 321 corresponds to a key region of the housing 2 (for example, the battery region of the battery cover, etc.). That is, the first weaving region 321 covers the key region of the housing 2.It should be noted that the embodiments of the present application do not limit the size of the set width of the continuous distribution. For example, Figure 5 as shown in Figure 5 , along the warp direction S, the set width a of the continuous distribution of the inorganic fiber E and the set width b of the continuous distribution of the organic fiber U are the same, and the set width a of the continuous distribution of each inorganic fiber E and the set width b of the continuous distribution of each organic fiber U are also the same. Moreover, along the weft direction W, the set width c of the continuous distribution of the inorganic fiber E and the set width d of the continuous distribution of the organic fiber U are the same, and the set width c of the continuous distribution of each inorganic fiber E and the set width d of the continuous distribution of each organic fiber U are also the same.

[0162] However, it is not limited thereto. For example, it may also be that the sizes of the above-mentioned set width a and set width b are different, or the sizes of each set width a and each set width b are different, or the sizes of set width c and set width d are different, or the sizes of each set width c and each set width d are different, or the sizes of set width a and set width c are the same, and the sizes of set width b and set width d are different, etc.

[0163] The above-mentioned second weaving area 322 (such as Figure 6 the E / U area in the upper left corner and the U / E area in the lower right corner shown in Figure 6 ) includes a plurality of second warp fibers 3221 and a plurality of second weft fibers 3222 that are mixed and woven. And the second weaving area 322 includes two types: the first type of second weaving area 322 (such as Figure 6 the E / U area in the upper left corner shown in Figure 6 ) includes inorganic fibers E (i.e., the second warp fibers 3221) with a continuously distributed set width a and organic fibers U (i.e., the second weft fibers 3222) with a continuously distributed set width d; the second type of second weaving area 322 (such as Figure 6 the U / E area in the lower right corner shown in Figure 6 ) includes organic fibers U (i.e., the second warp fibers 3221) with a continuously distributed set width b and inorganic fibers E (i.e., the second weft fibers 3222) with a continuously distributed set width c. That is, the second weaving area 322 is formed by mixing and weaving organic fibers U (such as the above-mentioned ultra-high molecular weight polyethylene fibers) and inorganic fibers E (such as the above-mentioned glass fibers) along the warp direction S and the weft direction W respectively.

[0164] Correspondingly, the third weaving area 323 (such as Figure 6The E / E region located in the lower left corner (as shown in []) includes a plurality of third warp fibers 3231 (i.e., inorganic fiber E) and a plurality of third weft fibers 3232 (i.e., inorganic fiber E) that are mixed and woven. Exemplarily, both the second weaving region 322 and the third weaving region 323 correspond to non-critical regions of the housing 2 (i.e., the edge region and the corner region, such as the periphery of the battery cover or the four corner regions). That is, the non-critical regions of the housing 2 include the edge region and the corner region, where the edge region surrounds the critical region, the corner region is adjacent to the edge region, the second weaving region 322 covers the edge region, and the third weaving region 323 covers the corner region.

[0165] And, as Figure 6 shown in [], when the second weaving region 322 is the first type of second weaving region 322 as described above (as Figure 6 shown in the E / U region located in the upper left corner of []), the fiber type of the third warp fiber 3231 (i.e., inorganic fiber E) in the third weaving region 323 is the same as the fiber type of the second warp fiber 3221 (i.e., inorganic fiber E), which is an inorganic fiber (such as the glass fiber described above); when the second weaving region 322 is the second type of second weaving region 322 as described above (as Figure 6 shown in the U / E region located in the lower right corner of []), the fiber type of the third weft fiber 3232 (i.e., inorganic fiber E) in the third weaving region 323 is the same as the fiber type of the second weft fiber 3222 (i.e., inorganic fiber E), which is an inorganic fiber (such as the glass fiber described above). That is, the third weaving region 323 (as Figure 6 shown in the E / E region located in the lower left corner of []) and the second weaving region 322 (as Figure 6 shown in the E / U region located in the upper left corner and the U / E region located in the lower right corner of []) are respectively connected by continuous inorganic fiber E.

[0166] Continuing to refer to Figure 6 (), both the first warp fiber 3211 and the second warp fiber 3221 of the second type of second weaving region 322 (as Figure 6 shown in the U / E region located in the lower right corner of []) are organic fibers U with a continuously distributed set width b, and both the first weft fiber 3212 and the second weft fiber 3222 of the first type of second weaving region 322 (as Figure 6 shown in the E / U region located in the upper left corner of []) are organic fibers U with a continuously distributed set width d. That is, the first weaving region 321 (as Figure 6 shown in the U / U region located in the upper right corner of []) and the second weaving region 322 (as Figure 6 shown in the E / U region located in the upper left corner and the U / E region located in the lower right corner of []) are respectively connected by continuous organic fibers U.

[0167] That is, the different braided regions 32 in the embodiments of the present application are respectively connected by continuous and unbroken organic fibers U and inorganic fibers E to form a continuous inner surface in the hybrid braided fiber layer 3, thereby improving the overall mechanical properties of the composite material structure 201.

[0168] It can be seen from this that as Figure 5 shown, the difference between the housing 2 of the embodiment of the present application and Figure 2 the housing 2' shown and Figure 3 the housing 2'' shown is that the composite material structure 201 serves as a core layer, and the hybrid braided fiber layer 3 therein is formed by hybrid braiding warp fibers 3111 and weft fibers 3121 having two types of inorganic fibers E and organic fibers U, and has a continuous inner surface. That is, the hybrid braided fiber layer 3 of the embodiment of the present application is neither made of a single fiber nor made by bonding or splicing organic fibers and inorganic fibers to each other.

[0169] Thus, in the hybrid braided fiber layer 3 of the embodiment of the present application, a plurality of braided regions 32 are formed (for example, the above-mentioned first braided region 321, second braided region 322, and third braided region 323). Since the types of the inorganic fibers E and organic fibers U are different, the material properties of the inorganic fibers E and organic fibers U are also different. Therefore, the material properties of the braided regions 32 formed by hybrid braiding the inorganic fibers E and organic fibers U also depend on the types of the inorganic fibers E and organic fibers U. That is, the material properties of the different braided regions 32 formed by hybrid braiding the inorganic fibers E and organic fibers U of different fiber types are also different. That is, the first braided region 321 (as shown in the U / U region in Figure 5 ), the second braided region 322 (as shown in the E / U region and U / E region in Figure 5 ), and the third braided region 323 (as shown in the E / E region in Figure 5 ) have different material properties.

[0170] Therefore, on the one hand, at least two braided regions 32 of the composite material structure 201 of the embodiment of the present application have different material properties, which can meet the requirement of the housing 2 for different material properties between multiple regions (for example, the above-mentioned key region and non-key region), so that multiple regions of the housing 2 (for example, the above-mentioned key region and non-key region) can be mapped to multiple devices of the electronic device 1 (for example, the above-mentioned battery, etc.) to obtain better product performance.

[0171] On the other hand, different braided regions 32 of the composite material structure 201 are interconnected by continuous inorganic fibers E and organic fibers U, such that the inner surfaces between the respective braided regions 32 of the composite material structure 201 are continuous without interruption, improving the overall mechanical properties of the composite material structure 201 and thus improving the overall mechanical properties of the housing 2.

[0172] In addition, in the embodiment of the present application, the composite material structure 201 is formed by hybrid weaving of organic fibers U and inorganic fibers E, such that the coverage rate of the organic fibers U in the non-critical regions of the above-mentioned housing 2 is reduced, the usage amount of the organic fibers U is decreased and the utilization rate of the organic fibers U is higher, effectively reducing the cost of the composite material structure 201.

[0173] As described above, the composite material laminated structure provided by the embodiment of the present application is prepared from the above-mentioned composite material structure 201, and the housing 2 is prepared from the composite material laminated structure.

[0174] In the embodiment of the present application, the composite material structure 201 is formed by hybrid weaving of organic fibers U and inorganic fibers E, and the prepreg of the composite material structure 201 is cut and laminated to form a housing 2 with different performances in each region (such as the above-mentioned critical region and non-critical region).

[0175] However, the embodiment of the present application does not specifically limit the manufacturing process of the housing 2. The following Figures 4a to 8 exemplarily illustrates the manufacturing method of the housing 2.

[0176] Step 1: Hybrid weave organic fibers and inorganic fibers to form a hybrid woven fabric.

[0177] Here, the set widths (i.e., the above-mentioned set widths a, b, c, and d) in which the two types of warp fibers 3111 and weft fibers 3121 are continuously distributed are determined by the final application structure (such as the above-mentioned electronic device 1). For the convenience of description below, the electronic device 1 is taken as an example of a mobile phone for illustration.

[0178] Exemplarily, as Figure 5 shown, in the hybrid woven fabric (i.e., the above-mentioned hybrid woven fiber layer 3), the organic fibers (such as the above-mentioned ultra-high molecular weight polyethylene fibers, as Figure 5 indicated by U therein) and inorganic fibers (such as the above-mentioned glass fibers, as Figure 5 indicated by E therein) in the warp fiber body 311 and weft fiber body 312 are continuously distributed in set widths respectively, and the two types of fibers are alternately distributed, and the set widths in which the organic fibers and inorganic fibers are continuously distributed are the same. That is, the size of set width a is the same as that of set width b, and the size of set width c is the same as that of set width d.

[0179] Step 2: Pre-impregnate the hybrid woven fabric in Step 1 with resin to obtain a corresponding pre-impregnated hybrid woven fabric.

[0180] Here, the hybrid woven fabric (i.e., the above-mentioned hybrid woven fiber layer 3) is pre-impregnated with resin to obtain a corresponding pre-impregnated hybrid woven fabric (i.e., the above-mentioned composite material structure 201). Exemplarily, the resin is mainly filled in the voids of the hybrid woven fabric and levels the surface of the hybrid fiber fabric, that is, there is a resin matrix on the surface of the hybrid woven fabric to cover the hybrid woven fabric and make the surface of the hybrid woven fabric smooth. That is, the hybrid woven fiber layer 3 is located inside the resin matrix.

[0181] Step 3: Cut the pre-impregnated hybrid woven fabric in Step 2.

[0182] Here, the cutting size of the pre-impregnated hybrid woven fabric (i.e., the above-mentioned composite material structure 201) corresponds to the key areas and non-key areas (i.e., the peripheral areas of the product key areas and the four corner areas of the product) of the final product (i.e., the above-mentioned housing 2). That is, the multiple woven areas 32 with different material properties of the above-mentioned hybrid woven fiber layer 3 are mapped and corresponded to the above-mentioned multiple areas (i.e., key areas and non-key areas) of the housing 2.

[0183] According to the foregoing, different components in the electronic device 1 correspond to different areas of the housing 2, so there is also a corresponding relationship between the multiple woven areas 32 of the hybrid woven fiber layer 3 and the electronic device 1.

[0184] Reference Figure 7 , Figure 7 shows a schematic diagram of the corresponding relationship between multiple woven areas of an embodiment of the present application and an electronic device. Among them, the electronic device 1 (i.e., the above-mentioned mobile phone) includes a battery 112, and the hybrid woven fiber layer 3 includes a first woven area 321 (as shown in the U / U area in Figure 7 ), four second woven areas 322 (as shown in the E / U area and U / E area in Figure 7 ), and four third woven areas 323 (as shown in the E / E area in Figure 7 ). Exemplarily, the composite material structure 201 is used for the back cover 12 of the electronic device 1.

[0185] Specifically, as shown in Figure 7 , a first woven area 321 (as shown in the U / U area in Figure 7 ) corresponds to the battery 112, four second woven areas 322 (as shown in the E / U area and U / E area in Figure 7 ) correspond to the peripheral areas of the battery 112, and four third woven areas 323 (as shown in the E / E area in Figure 7 ) are respectively adjacent to the four second woven areas 322 (as shown in Figure 7as shown in the E / U region and the U / E region), and corresponding to the four corner regions of the mobile phone.

[0186] Among them, the first warp fibers (i.e., organic fiber U) and the first weft fibers (i.e., organic fiber U) of the first braided region 321 (as Figure 7 shown in the U / U region) are both ultra-high molecular weight polyethylene fibers. The second warp fibers and the second weft fibers (i.e., inorganic fiber E and organic fiber U) of the second braided region 322 (as Figure 7 shown in the E / U region and the U / E region) are ultra-high molecular weight polyethylene fibers and glass fibers respectively. The third warp fibers (i.e., inorganic fiber E) and the third weft fibers (i.e., inorganic fiber E) of the third braided region 323 (as Figure 7 shown in the E / E region) are both glass fibers.

[0187] Step 4: Stack the cut mixed braided fabric prepreg in Step 3 with a single braided prepreg. The single braided prepreg serves as the stacked surface layer, and the mixed braided fabric prepreg serves as the core layer.

[0188] Here, continue to refer to Figure 4b , along the stacking direction (i.e., the thickness direction of the housing 2, as Figure 4b shown in the Z direction in

[0189] ), the single braided fiber layers 202 are stacked on both sides opposite to the mixed braided fabric prepreg (i.e., the above-mentioned composite material structure 201) to form the above-mentioned composite material stacked structure.

[0190] Here, continue to refer to Figure 4a and combine with Figure 8 , stack the surface treatment layer 203 on the single braided fiber layer 202 in the composite material stacked structure, and process the dimensions to obtain the final product (for example, the above-mentioned housing 2). Figure 8 A schematic diagram showing the correspondence between the housing of the embodiment of the present application and multiple braided regions. Among them, the above-mentioned multiple braided regions 32 are mapped and corresponding to multiple regions of the housing 2 (i.e., the above-mentioned key regions and non-key regions). The multiple braided regions 32 have different material properties, so that the material properties of each region of the housing 2 are also different.

[0191] Specifically, as Figure 8 shown, one first braided region 321 (as Figure 8 shown in the U / U region) is mapped and corresponding to cover the key region of the housing 2 (i.e., the region corresponding to the above-mentioned battery 112) to improve the protection ability of the housing 2 for the battery 112 of the mobile phone; four second braided regions 322 (as Figure 8The mapping corresponding to the E / U region and the U / E region covers the peripheral regions (i.e., the four edge regions of the housing 2) that are key regions of the housing 2. By adding inorganic fiber E, the bonding force between the organic fiber U and the resin is improved, and there are four third braided regions 323 (as shown in the Figure 8 E / E region in the figure) respectively adjacent to the four second braided regions 322 (as shown in the Figure 8 E / U region and the U / E region in the figure), and covering the four corner regions of the housing 2 to further enhance the bonding force between the hybrid braided fiber layer 3 and the resin.

[0192] Thus, the key region of the housing 2 (i.e., the region corresponding to the above-mentioned battery, as shown in the Figure 8 U / U region in the figure) is mapped and corresponding to the first braided region 321 formed by hybrid braiding of organic fiber U (for example, ultra-high molecular weight polyethylene fiber) to obtain better safety protection. The non-key regions of the housing 2, such as the four corner regions of the housing 2 (i.e., the regions corresponding to the four corners of the above-mentioned mobile phone, as shown in the Figure 8 E / E region in the figure) are mapped and corresponding to the third braided region 323 formed by hybrid braiding of inorganic fiber E (for example, glass fiber), and better interlayer bonding force can be obtained. Also, the four side regions of the housing 2 (i.e., the regions corresponding to the four sides of the above-mentioned mobile phone, as shown in the Figure 8 E / U region and the U / E region in the figure) are mapped and corresponding to the second braided region 322 formed by hybrid braiding of organic fiber U and inorganic fiber E. The presence of inorganic fiber E improves the bonding force between the layers, thereby improving the overall stiffness of the housing 2. At the same time, the mixed use of organic fiber U and inorganic fiber E can reduce the usage amount of organic fiber U, improve the utilization rate of organic fiber, and significantly reduce the raw material cost.

[0193] In the embodiment of the present application, by pre-impregnating, cutting, and laminating the composite material structure 201 having a positional and dimensional correspondence relationship with the application product (for example, the above-mentioned mobile phone), the braided regions 32 having different material properties therein correspond to different components of the application product (for example, the above-mentioned mobile phone), and then a final product (i.e., the above-mentioned housing 2) in which the key regions and non-key regions correspond to different components of the application product (for example, the above-mentioned mobile phone) is obtained to meet different performance requirements in different regions and obtain better product performance.

[0194] In the above embodiments, multiple braided regions 32 of the embodiments of the present application (i.e., the first braided region 321, the second braided region 322, and the third braided region 323 mentioned above) are mapped to correspond to multiple components of the electronic device 1 (i.e., the battery 112, etc. mentioned above). However, the embodiments of the present application do not limit the corresponding relationship between the multiple components of the electronic device 1 and the multiple regions of the housing 2. As long as at least one braided region 32 is assembled with the electronic device 1, at least one braided region 32 is mapped to correspond to different components of the electronic device 1. For example, the components of the electronic device 1 in the embodiments of the present application may further include a main board or a daughter board, and at least one braided region 32 is mapped to correspond to the main board or the daughter board of the electronic device 1. The following will exemplarily illustrate the components of the electronic device 1 and the corresponding housing 2 in some application scenarios with reference to the accompanying drawings.

[0195] Reference Figure 9 , Figure 9 shows a schematic diagram of the corresponding relationship between multiple braided regions 32 provided in another embodiment of the present application and the electronic device 1.

[0196] Exemplarily, as Figure 9 shown, the electronic device 1 (i.e., the mobile phone mentioned above) includes two radio frequency components 113. Along the weft direction W, the two radio frequency components 113 are respectively arranged on the left and right sides of the electronic device 1 and correspond to the key regions of the housing 2 mentioned above. The electronic device 1 further includes multiple other components (not shown in the figure), which correspond to the non-key regions of the housing 2. The embodiments of the present application do not specifically limit the types of other components. The hybrid braided fiber layer 3 is formed by hybrid braiding inorganic fibers (such as Figure 9 shown as E in Figure 9 ) and organic fibers (such as Figure 9 shown as U in Figure 9 ), and includes four first braided regions 321 (such as Figure 9 shown as the E / E region in Figure 9 ), eight second braided regions 322 (such as Figure 9 shown as the E / U region and the U / E region in Figure 9 ), and three third braided regions 323 (such as Figure 9 shown as the U / U region in

[0197] . The four first braided regions 321 (such as Figure 9Both the first warp fibers and the first weft fibers in the E / E region (as shown) are glass fibers, and the second warp fibers and the second weft fibers in the second weaving region 322 (as shown in the E / U region and the U / E region) are glass fibers and carbon fibers respectively, and the third warp fibers and the third weft fibers in the third weaving region 323 (as shown in the U / U region) are both carbon fibers. Figure 9 In the E / U region and the U / E region, the second warp fibers and the second weft fibers are glass fibers and carbon fibers respectively, and in the third weaving region 323 (as shown in the U / U region) Figure 9 the third warp fibers and the third weft fibers are both carbon fibers.

[0198] Thus, as in the above embodiments, the key region of the housing 2 (i.e., the region corresponding to the radio frequency device 113, as shown in the E / E region) is woven from inorganic fiber E (for example, glass fiber) so as not to shield the radio frequency device 113, achieving the non-shielding function, while the non-key regions of the housing 2 (i.e., the regions corresponding to the periphery and the four corner regions of the radio frequency device 113, as shown in the E / U region, the U / E region, and the U / U region) Figure 9 are woven from a mixture of inorganic fiber E (for example, glass fiber) and organic fiber U (for example, carbon fiber). By utilizing the high strength and high rigidity of the carbon fiber, the overall stiffness of the housing 2 is improved. Figure 9 In the E / U region, the U / E region, and the U / U region) are woven from a mixture of inorganic fiber E (for example, glass fiber) and organic fiber U (for example, carbon fiber). By utilizing the high strength and high rigidity of the carbon fiber, the overall stiffness of the housing 2 is improved.

[0199] Reference Figure 10 , Figure 10 shows a schematic diagram of the correspondence between the plurality of weaving regions 32 provided in another embodiment of the present application and the electronic device 1.

[0200] Exemplarily, as shown in Figure 10 , the electronic device 1 (i.e., the above-mentioned mobile phone) includes a dielectric property sensitive radio frequency device 113. Along the weft direction W, a dielectric property sensitive radio frequency device 113 is provided in the middle part of the electronic device 1 and corresponds to the key region of the housing 2 described above. The electronic device 1 further includes a plurality of other devices (not shown in the figure), which correspond to the non-key regions of the housing 2. The types of the other devices are not specifically limited in the embodiments of the present application. The hybrid woven fiber layer 3 is woven from two types of inorganic fibers (as shown by E1 and E2 in Figure 10 ) and includes a first weaving region 321 (as shown in the E2 / E2 region in Figure 10 ), six second weaving regions 322 (as shown in the E1 / E2 region and the E2 / E1 region in Figure 9 ) and eight third weaving regions 323 (as shown in the E1 / E1 region in Figure 10 ). A first weaving region 321 (as shown in the E2 / E2 region in Figure 10 ) is mapped to cover the dielectric property sensitive radio frequency device 113 correspondingly, and six second weaving regions 322 (as shown in Figure 9The mapping corresponding to the E1 / E2 region and the E2 / E1 region (as shown) covers the peripheral region of the dielectric property sensitive radio frequency device 113, and eight third braided regions 323 (as Figure 10 shown in the E1 / E1 region in) are respectively adjacent to six second braided regions 322 (as Figure 9 shown in the E1 / E2 region and the E2 / E1 region in) and the mapping corresponding to cover the four corner regions of the electronic device 1.

[0201] Among them, the first warp fibers and the first weft fibers of the first braided region 321 (as Figure 10 shown in the E2 / E2 region in) are both quartz fibers (as Figure 10 shown in E2 in), and the fiber types of the second warp fibers and the second weft fibers of the second braided region 322 (as Figure 9 shown in the E1 / E2 region and the E2 / E1 region in) include quartz fibers and glass fibers (as Figure 10 shown in E1 in), and the third warp fibers and the third weft fibers of the third braided region 323 (as Figure 10 shown in the E1 / E1 region in) are both glass fibers.

[0202] Thus, as in the above embodiment, the key region of the housing 2 (i.e., the region corresponding to the above dielectric property sensitive radio frequency device 113) is woven by mixing inorganic fibers E2 (such as quartz fibers), and the dielectric loss of quartz fibers is low, which can avoid adverse effects on the dielectric property sensitive radio frequency device 113, while the non-key regions of the housing 2 (i.e., the peripheral regions and the four corner regions of the region corresponding to the dielectric property sensitive radio frequency device 113) are woven by mixing inorganic fibers E1 (such as glass fibers) and inorganic fibers E2 (such as quartz fibers), which can reduce the usage amount of quartz fibers, improve the utilization rate of quartz fibers, and significantly reduce the raw material cost.

[0203] In the above embodiment, the mixed woven fiber layer 3 includes two types of warp fibers and two types of weft fibers, and the fiber types include organic fiber U and inorganic fiber E.

[0204] However, in the embodiment of the present application, there are no specific limitations on the type quantity and fiber types of the warp fibers and the weft fibers in the mixed woven fiber layer 3, as long as it can satisfy that at least one direction (i.e., the warp direction or the weft direction) has more than two types of fibers.

[0205] The following will give an exemplary illustration of the type quantity and fiber types of the warp fibers and the weft fibers in the mixed woven fiber layer 3 in conjunction with the drawings.

[0206] In a possible implementation manner, Figure 11a shows a schematic structural diagram of a mixed woven fiber layer 3 provided by an embodiment of the present application. Refer toFigure 11a , in the hybrid woven fiber layer 3, the types and quantities of the warp fibers 3111 and weft fibers 3121 and the fiber types can also be: two different types of warp fibers 3111 (i.e., A fibers and B fibers, as shown by A and B in Figure 11a ) that are continuously distributed in sequence along the weft direction W and the same type of weft fiber 3121 (i.e., B fibers) that are continuously distributed along the warp direction S. That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes two types of warp fibers 3111, the weft fiber body 312 includes one type of weft fiber 3121, and the fiber types include two types, A fibers and B fibers.

[0207] Specifically, the two types of warp fibers 3111 (i.e., A fibers and B fibers) and one type of weft fiber 3121 (i.e., B fibers) are mixed and woven along the weft direction W and the warp direction S respectively to form the hybrid woven fiber layer 3. Moreover, the A fibers among the two types of warp fibers 3111 are continuously distributed along the weft direction W with a set width a, the B fibers are continuously distributed along the weft direction W with a set width b, and the B fibers among the one type of weft fiber 3121 are continuously distributed along the warp direction S with a set width c.

[0208] That is, within the set width a, multiple warp fibers 3111 of the same type (i.e., A fibers) are continuously distributed, within the set width b, multiple warp fibers 3111 of the same type (i.e., B fibers) are continuously distributed, and within the set width c, multiple weft fibers 3121 of the same type (i.e., B fibers) are continuously distributed. That is to say, the B fibers are continuously distributed throughout the warp direction S.

[0209] Thus, the A fibers and B fibers together form the hybrid woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include two different weaving regions 32 (as shown by the A / B region and B / B region in Figure 11a ), and the two different weaving regions 32 have different material properties, and thus the multiple different weaving regions 32 can be mapped and corresponding to multiple components of the electronic device.

[0210] Exemplarily, the fiber type of the A fibers includes organic fibers, the fiber type of the B fibers includes inorganic fibers; or, the fiber type of the A fibers includes inorganic fibers, the fiber type of the B fibers includes organic fibers; or, the fiber type of the A fibers includes organic fibers, the fiber type of the B fibers includes organic fibers; or, the fiber type of the A fibers includes inorganic fibers, the fiber type of the B fibers includes inorganic fibers.

[0211] That is, fiber A and fiber B can be any one of organic fibers and inorganic fibers respectively, as long as one of them is an organic fiber and the other is an inorganic fiber; or, fiber A and fiber B can be any one of organic fibers or inorganic fibers, as long as the fiber types of fiber A and fiber B are different.

[0212] In a possible implementation, Figure 11b Fig. shows a schematic diagram of the structure of another hybrid woven fiber layer 3 provided by an embodiment of the present application. Refer to Figure 11b , in the hybrid woven fiber layer 3, the types and quantities of the warp fibers 3111 and the weft fibers 3121 can also be: A fibers continuously distributed along the weft direction W (such as Figure 11b shown as A in Figure 11b ), A fibers and B fibers alternately distributed (such as

[0213] shown as A and B in

[0214] ), and the same type of weft fibers 3121 (i.e., B fibers) continuously distributed along the warp direction S. That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes two types of warp fibers 3111, the weft fiber body 312 includes one type of weft fiber 3121, and the fiber types include two types, A fibers and B fibers.

[0215] Specifically, two types of warp fibers 3111 (i.e., A fibers and B fibers) and one type of weft fiber 3121 (i.e., B fibers) are mixed and woven along the weft direction W and the warp direction S respectively to form the hybrid woven fiber layer 3. And, a part of the A fibers in the two types of warp fibers 3111 is continuously distributed along the weft direction W with a set width a, another part of the A fibers and the B fibers are alternately distributed along the weft direction W with a set width b, and the B fibers in the one type of weft fiber 3121 are continuously distributed along the warp direction S with a set width c. Figure 11b That is, within the set width a, multiple warp fibers 3111 of the same type (i.e., A fibers) are continuously distributed, within the set width b, multiple warp fibers 3111 of different types (i.e., A fibers and B fibers) are alternately distributed, and within the set width c, multiple weft fibers 3121 of the same type (i.e., B fibers) are continuously distributed. That is to say, the B fibers are continuously distributed throughout the warp direction S, and the A fibers and the B fibers are alternately distributed along the weft direction W with a certain width (i.e., the set width b).

[0216] Exemplarily, the fiber type of A fiber includes organic fiber, and the fiber type of B fiber includes inorganic fiber; or, the fiber type of A fiber includes inorganic fiber, and the fiber type of B fiber includes organic fiber; or, the fiber type of A fiber includes organic fiber, and the fiber type of B fiber includes organic fiber; or, the fiber type of A fiber includes inorganic fiber, and the fiber type of B fiber includes inorganic fiber.

[0217] That is, A fiber and B fiber can be any one of organic fiber and inorganic fiber respectively, as long as one of them is organic fiber and the other is inorganic fiber; or, A fiber and B fiber can be any one of organic fiber or inorganic fiber, as long as the fiber types of A fiber and B fiber are different.

[0218] In a possible implementation manner, Figure 11c shows a schematic structural diagram of another hybrid woven fiber layer 3 provided by an embodiment of the present application. Refer to Figure 11c , the type quantity and fiber type of the warp fibers 3111 and weft fibers 3121 in the hybrid woven fiber layer 3 can also be: A fiber and C fiber (as shown by A and C in Figure 11c ) that are alternately distributed along the weft direction W, A fiber and B fiber (as shown by A and B in Figure 11c ), and the same type of weft fiber 3121 (i.e., B fiber) that is continuously distributed along the warp direction S. That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes three types of warp fibers 3111, the weft fiber body 312 includes one type of weft fiber 3121, and the fiber types include three types: A fiber, B fiber, and C fiber.

[0219] Specifically, three types of warp fibers 3111 (i.e., A fiber, B fiber, and C fiber) and one type of weft fiber 3121 (i.e., B fiber) are mixed and woven along the weft direction W and warp direction S respectively to form the hybrid woven fiber layer 3. Moreover, a part of A fiber and C fiber among the three types of warp fibers 3111 are alternately distributed along the weft direction W with a set width a, another part of A fiber and B fiber are alternately distributed along the weft direction W with a set width b, and the B fiber among the one type of weft fiber 3121 is continuously distributed along the warp direction S with a set width c.

[0220] That is, within the set width a, multiple warp fibers 3111 of different types (i.e., A fibers and C fibers) are alternately distributed. Within the set width b, multiple warp fibers 3111 of different types (i.e., A fibers and B fibers) are alternately distributed. Within the set width c, multiple weft fibers 3121 of the same type (i.e., B fibers) are continuously distributed. That is, B fibers are continuously distributed throughout the warp direction S, A fibers and C fibers are alternately distributed in a certain width along the weft direction W (i.e., the set width a), and A fibers and B fibers are alternately distributed in a certain width along the weft direction W (i.e., the set width b).

[0221] Thus, A fibers, B fibers, and C fibers together form a hybrid woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include two different weaving regions 32 (as shown by the AC / B region and the AB / B region in Figure 11c ), and the two different weaving regions 32 have different material properties. Furthermore, the multiple different weaving regions 32 can be mapped to multiple components of the electronic device in a corresponding manner.

[0222] Exemplarily, the fiber type of one type of weft fiber 3121 (i.e., B fiber) includes organic fiber or inorganic fiber, and the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include at least two types of organic fibers; or,

[0223] the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include at least two types of organic fibers or inorganic fibers; or,

[0224] the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include organic fibers and inorganic fibers.

[0225] In a possible implementation manner, Figure 11d shows a schematic structural diagram of yet another hybrid woven fiber layer 3 provided by an embodiment of the present application. Referring to Figure 11d , the type quantity and fiber types of the warp fibers 3111 and the weft fibers 3121 in the above-mentioned hybrid woven fiber layer 3 can also be: the same type of warp fibers 3111 (i.e., A fibers) continuously distributed in sequence along the weft direction W and two different types of weft fibers 3121 (i.e., A fibers and B fibers, as shown by A and B in Figure 11d ) continuously distributed along the warp direction S. That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes one type of warp fiber 3111, the weft fiber body 312 includes two types of weft fibers 3121, and the fiber types include two types, namely A fibers and B fibers.

[0226] Specifically, one type of warp fiber 3111 (i.e., A fiber) and two types of weft fibers 3121 (i.e., A fiber and B fiber) are respectively mixed and woven along the weft direction W and the warp direction S to form a mixed woven fiber layer 3. Moreover, the B fiber among the two types of weft fibers 3121 is continuously distributed along the warp direction S with a set width c, the A fiber is continuously distributed along the warp direction S with a set width d, and the A fiber among one type of warp fiber 3111 is continuously distributed along the weft direction W with a set width a.

[0227] That is, within the set width a, multiple warp fibers 3111 of the same type (i.e., A fiber) are continuously distributed. Within the set width c, multiple weft fibers 3121 of the same type (i.e., B fiber) are continuously distributed. Within the set width d, multiple weft fibers 3121 of the same type (i.e., A fiber) are continuously distributed. That is to say, the A fiber is continuously distributed throughout the weft direction W.

[0228] Thus, the A fiber and the B fiber jointly form a mixed woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include two different weaving regions 32 (such as Figure 11d shown as the A / A region and the A / B region in

[0229] Exemplarily, the fiber type of the A fiber includes organic fiber, and the fiber type of the B fiber includes inorganic fiber; or, the fiber type of the A fiber includes inorganic fiber, and the fiber type of the B fiber includes organic fiber; or, the fiber type of the A fiber includes organic fiber, and the fiber type of the B fiber includes organic fiber; or, the fiber type of the A fiber includes inorganic fiber, and the fiber type of the B fiber includes inorganic fiber.

[0230] That is, the A fiber and the B fiber can respectively be any one of organic fiber and inorganic fiber, as long as one of them is an organic fiber and the other is an inorganic fiber; or, the A fiber and the B fiber can be any one of organic fiber or inorganic fiber, as long as the fiber types of the A fiber and the B fiber are different.

[0231] In a possible implementation manner, Figure 11e shows a schematic structural diagram of another mixed woven fiber layer 3 provided by an embodiment of the present application. Referring to Figure 11e , the number of types and the fiber types of the warp fibers 3111 and the weft fibers 3121 in the mixed woven fiber layer 3 can also be: the B fiber continuously distributed along the warp direction S (such as Figure 11e shown as B in Figure 11eAs shown in A, B, and C, and the same kind of weft fibers 3121 (i.e., A fibers) continuously distributed along the weft direction W. That is, the weft fiber body 312 of the hybrid woven fiber layer 3 includes three kinds of weft fibers 3121, and the warp fiber body 311 includes one kind of warp fiber 3111. The fiber types include three types: A fibers, B fibers, and C fibers.

[0232] Specifically, three kinds of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) and one kind of warp fiber 3111 (i.e., A fibers) are respectively mixed and woven along the warp direction S and the weft direction W to form the hybrid woven fiber layer 3. And, a part of the B fibers among the three kinds of weft fibers 3121 is continuously distributed along the warp direction S with a set width c, another part of the A fibers is alternately distributed with the B fibers and C fibers along the warp direction S with a set width d, and the A fibers of the one kind of warp fiber 3111 are continuously distributed along the weft direction W with a set width a.

[0233] That is, within the set width a, multiple warp fibers 3111 of the same kind (i.e., A fibers) are continuously distributed. Within the set width c, multiple weft fibers 3121 of the same kind (i.e., B fibers) are continuously distributed. Within the set width d, multiple different kinds of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) are alternately distributed. That is, the A fibers are continuously distributed throughout the weft direction W, and the A fibers, B fibers, and C fibers are alternately distributed along the warp direction S with a certain width (i.e., the set width d).

[0234] Thus, the A fibers, B fibers, and C fibers together form a hybrid woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include two different weaving regions 32 (as Figure 11e shown in the A / B region and the A / ABC region in), then the two different weaving regions 32 have different material properties, and further, the multiple different weaving regions 32 can be mapped to multiple devices of the electronic device 1.

[0235] Exemplarily, the fiber type of one kind of warp fiber 3111 (i.e., A fibers) includes organic fibers or inorganic fibers, and the fiber types of the three kinds of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) include at least two kinds of organic fibers; or,

[0236] the fiber types of the three kinds of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) include at least two kinds of organic fibers or inorganic fibers; or,

[0237] the fiber types of the three kinds of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) include organic fibers and inorganic fibers.

[0238] In a possible implementation, Figure 11f Fig. shows a schematic structural diagram of yet another hybrid woven fiber layer 3 provided by an embodiment of the present application. Refer to Figure 11f , the types and quantities of the warp fibers 3111 and weft fibers 3121 in the hybrid woven fiber layer 3 and the fiber types may also be: A fibers and B fibers (such as A and B shown in Figure 11f ) that are alternately distributed along the warp direction S, A fibers, B fibers, and C fibers (such as A, B, and C shown in Figure 11f ), and the same type of weft fiber 3121 (i.e., A fiber) that is continuously distributed along the weft direction W. That is, the weft fiber body 312 of the hybrid woven fiber layer 3 includes three types of weft fibers 3121, the warp fiber body 311 includes one type of warp fiber 3111, and the fiber types include three types: A fiber, B fiber, and C fiber.

[0239] Specifically, three types of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) and one type of warp fiber 3111 (i.e., A fiber) are respectively mixed and woven along the warp direction S and the weft direction W to form the hybrid woven fiber layer 3. Moreover, a part of the A fibers and B fibers among the three types of weft fibers 3121 are alternately distributed along the warp direction S with a set width c, another part of the A fibers, B fibers, and C fibers are alternately distributed along the warp direction S with a set width d, and the A fibers of the one type of warp fiber 3111 are continuously distributed along the weft direction W with a set width a.

[0240] That is, within the set width a, multiple warp fibers 3111 of the same type (i.e., A fibers) are continuously distributed. Within the set width c, multiple weft fibers 3121 of different types (i.e., A fibers and B fibers) are alternately distributed. Within the set width d, multiple warp fibers 3111 of different types (i.e., A fibers, B fibers, and C fibers) are alternately distributed. That is, the A fibers are continuously distributed throughout the weft direction W, the A fibers and B fibers are alternately distributed along the warp direction S with a certain width (i.e., the set width c), and the A fibers, B fibers, and C fibers are alternately distributed along the warp direction S with a certain width (i.e., the set width d).

[0241] Thus, the A fibers, B fibers, and C fibers together form the hybrid woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include two different weaving regions 32 (such as the A / AB region and the A / ABC region shown in Figure 11f ), and the two different weaving regions 32 have different material properties. Furthermore, the multiple different weaving regions 32 can be mapped and corresponded to multiple devices of the electronic device 1.

[0242] Exemplarily, the fiber types of one type of warp fiber 3111 (i.e., A fiber) include organic fibers or inorganic fibers, and the fiber types of three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) include at least two types of organic fibers; or,

[0243] the fiber types of three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) include at least two types of organic fibers or inorganic fibers; or,

[0244] the fiber types of three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) include organic fibers and inorganic fibers.

[0245] In a possible implementation manner, Figure 11g Fig. shows a schematic structural diagram of yet another hybrid woven fiber layer 3 provided by an embodiment of the present application. Refer to Figure 11g , the number of types and fiber types of the warp fibers 3111 and weft fibers 3121 in the above-mentioned hybrid woven fiber layer 3 may also be: A fibers continuously distributed along the weft direction W (as shown by A in Figure 11g ), and alternately distributed A fibers and B fibers (as shown by A and B in Figure 11g ), and B fibers continuously distributed along the warp direction S (as shown by B in Figure 11g ), and alternately distributed C fibers and D fibers (as shown by C and D in Figure 11g ). That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes two types of warp fibers 3111, the weft fiber body 312 includes three types of weft fibers 3121, and the fiber types include four types: A fiber, B fiber, C fiber, and D fiber.

[0246] Specifically, two types of warp fibers 3111 (i.e., A fiber and B fiber) and three types of weft fibers 3121 (i.e., B fiber, C fiber, and D fiber) are mixed and woven along the weft direction W and the warp direction S respectively to form the hybrid woven fiber layer 3. And, the A fiber in the two types of warp fibers 3111 is continuously distributed along the weft direction W with a set width a, and the A fiber and B fiber are alternately distributed along the weft direction W with a set width b. The B fiber in the three types of weft fibers 3121 is continuously distributed along the warp direction S with a set width c, and the C fiber and D fiber are continuously distributed along the warp direction S with a set width d.

[0247] That is, within the set width a, multiple warp fibers 3111 of the same type (i.e., A fibers) are continuously distributed. Within the set width b, multiple warp fibers 3111 of different types (i.e., A fibers and B fibers) are alternately distributed. Within the set width c, multiple weft fibers 3121 of the same type (i.e., B fibers) are continuously distributed. Within the set width d, multiple weft fibers 3121 of the same type (i.e., C fibers and D fibers) are alternately distributed. The A fibers and B fibers are alternately distributed along the weft direction W for a certain width (i.e., the set width b), and the C fibers and D fibers are alternately distributed along the warp direction S for a certain width (i.e., the set width d).

[0248] Thus, the A fibers, B fibers, C fibers, and D fibers together form a hybrid woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include four different weaving regions 32 (such as Figure 11g shown by the A / B region, AB / B region, A / CD region, and AB / CD region in). Then, the four different weaving regions 32 have different material properties, and further, the multiple different weaving regions 32 can be mapped to multiple components of the electronic device.

[0249] Exemplarily, the fiber types of the two types of warp fibers 3111 (i.e., A fibers and B fibers) or the three types of weft fibers 3121 (i.e., B fibers, C fibers, and D fibers) include organic fibers or inorganic fibers, and the three types of weft fibers 3121 (i.e., B fibers, C fibers, and D fibers) or the two types of warp fibers 3111 (i.e., A fibers and B fibers) include at least two types of organic fibers; or,

[0250] the three types of weft fibers 3121 (i.e., B fibers, C fibers, and D fibers) or the two types of warp fibers 3111 (i.e., A fibers and B fibers) include at least two types of organic fibers or inorganic fibers; or,

[0251] the three types of weft fibers 3121 (i.e., B fibers, C fibers, and D fibers) or the two types of warp fibers 3111 (i.e., A fibers and B fibers) include organic fibers and inorganic fibers.

[0252] In a possible implementation manner, Figure 11h shows a schematic diagram of the structure of another hybrid woven fiber layer 3 provided by the embodiment of the present application. Refer to Figure 11h , the type numbers and fiber types of the warp fibers 3111 and weft fibers 3121 in the above-mentioned hybrid woven fiber layer 3 can also be: A fibers, C fibers, and D fibers alternately distributed along the weft direction W (such as Figure 11h shown by A, C, and D in), A fibers and B fibers (such as Figure 11has shown by A and B in the figure), and A fibers and B fibers (as shown by A and B in the figure), C fibers and D fibers (as shown by C and D in the figure) that are alternately distributed along the meridional direction S. That is, the meridional fiber body 311 of the hybrid woven fiber layer 3 includes four types of meridional fibers 3111, the zonal fiber body 312 includes four types of zonal fibers 3121, and the fiber types include four types: A fibers, B fibers, C fibers, and D fibers. Figure 11h as shown by A and B in the figure), C fibers and D fibers (as shown by C and D in the figure). Figure 11h That is, the meridional fiber body 311 of the hybrid woven fiber layer 3 includes four types of meridional fibers 3111, the zonal fiber body 312 includes four types of zonal fibers 3121, and the fiber types include four types: A fibers, B fibers, C fibers, and D fibers.

[0253] Specifically, four types of meridional fibers 3111 (i.e., A fibers, B fibers, C fibers, and D fibers) and four types of zonal fibers 3121 (i.e., A fibers, B fibers, C fibers, and D fibers) are mixed and woven along the zonal direction W and the meridional direction S respectively to form the hybrid woven fiber layer 3. Moreover, a part of A fibers, C fibers, and D fibers among the four types of meridional fibers 3111 are continuously distributed along the zonal direction W with a set width a, and the other part of A fibers and B fibers are alternately distributed along the zonal direction W with a set width b. A fibers and B fibers among the four types of zonal fibers 3121 are alternately distributed along the meridional direction S with a set width c, and C fibers and D fibers are continuously distributed along the meridional direction S with a set width d.

[0254] That is, within the set width a, multiple meridional fibers 3111 of different types (i.e., A fibers, C fibers, and D fibers) are alternately distributed. Within the set width b, multiple meridional fibers 3111 of different types (i.e., A fibers and B fibers) are alternately distributed. Within the set width c, multiple zonal fibers 3121 of different types (i.e., A fibers and B fibers) are continuously distributed. Within the set width d, multiple zonal fibers 3121 of different types (i.e., C fibers and D fibers) are alternately distributed. A fibers, C fibers, and D fibers are alternately distributed along the zonal direction W with a certain width (i.e., the set width a), A fibers and B fibers are alternately distributed along the zonal direction W with a certain width (i.e., the set width b), A fibers and B fibers are alternately distributed along the meridional direction S with a certain width (i.e., the set width c), and C fibers and D fibers are alternately distributed along the meridional direction S with a certain width (i.e., the set width d).

[0255] Thus, A fibers, B fibers, C fibers, and D fibers together form a hybrid woven fiber layer 3 having multiple weaving regions 32, where the multiple weaving regions 32 include four different weaving regions 32 (as shown by the ACD / AB region, AB / AB region, ACD / CD region, and AB / CD region in the figure). Then, the material properties of the four different weaving regions 32 are also different, and further, the multiple different weaving regions 32 can be mapped and corresponded to multiple components of the electronic device. Figure 11h as shown by the ACD / AB region, AB / AB region, ACD / CD region, and AB / CD region in the figure). Then, the material properties of the four different weaving regions 32 are also different, and further, the multiple different weaving regions 32 can be mapped and corresponded to multiple components of the electronic device.

[0256] Exemplarily, the fiber types of the four types of warp fibers 3111 (i.e., A fibers, B fibers, C fibers, and D fibers) or the four types of weft fibers 3121 (i.e., A fibers, B fibers, C fibers, and D fibers) include organic fibers or inorganic fibers, and the four types of weft fibers 3121 (i.e., A fibers, B fibers, C fibers, and D fibers) or the four types of warp fibers 3111 (i.e., A fibers, B fibers, C fibers, and D fibers) include at least two types of organic fibers; or,

[0257] the four types of weft fibers 3121 (i.e., A fibers, B fibers, C fibers, and D fibers) or the four types of warp fibers 3111 (i.e., A fibers, B fibers, C fibers, and D fibers) include at least two types of organic fibers or inorganic fibers; or,

[0258] the four types of weft fibers 3121 (i.e., A fibers, B fibers, C fibers, and D fibers) or the four types of warp fibers 3111 (i.e., A fibers, B fibers, C fibers, and D fibers) include organic fibers and inorganic fibers.

[0259] As described above, the above embodiments show that the fiber body in at least one direction has fibers of more than two different fiber types.

[0260] For example, as Figures 11a to 11c shown, the weft fiber body includes one type of weft fiber, and the warp fiber body includes two types (as Figure 11a and Figure 11b shown) and three types (as Figure 11c described) of warp fibers; or,

[0261] As Figures 11d to 11f shown, the weft fiber body includes two types (as Figure 11a shown) and three types (as Figure 11b and Figure 11f shown) of weft fibers, and the warp fiber body includes one type of warp fiber; or,

[0262] As Figure 11g and Figure 11h shown, the warp fiber body includes two types (as Figure 11g shown) and four types (as Figure 11h shown) of warp fibers, and the weft fiber body includes three types (as Figure 11g shown) and four types (as Figure 11h shown) of weft fibers.

[0263] However, it is not limited thereto. As long as at least one direction (i.e., the warp direction S or the weft direction W) of the embodiments of the present application has two or more types of fibers (e.g., two, three, four, five, six, seven or more types) (i.e., the warp fibers 3111 or the weft fibers 3121), it is sufficient.

[0264] For example, in the fibrous body having two or more types of fibers (e.g., the warp fibrous body 311 or the weft fibrous body 312) of the embodiments of the present application, at least one type (e.g., one, two, three, four, five, six, seven or more types) of fibers may be continuously distributed along the corresponding direction (i.e., the warp direction S or the weft direction W) with a set width.

[0265] However, it is not limited thereto. In the fibrous body having two or more types of fibers (e.g., the warp fibrous body 311 or the weft fibrous body 312) of the embodiments of the present application, at least two types of fibers (e.g., two, three, four, five, six, seven or more types) among two or more types of fibers (i.e., the warp fibers 3111 or the weft fibers 3121) may be alternately distributed along the corresponding direction (i.e., the warp direction S or the weft direction W).

[0266] Exemplarily, in the fibrous body having two or more types of fibers (e.g., the warp fibrous body 311 or the weft fibrous body 312), at least two types of fibers are alternately distributed along the corresponding direction (i.e., the warp direction or the weft direction) with a certain width.

[0267] For example Figure 11c 、 Figure 11f and Figure 11h As shown, at least two types of fibers are alternately distributed along the warp direction or the weft direction with a certain width, and the ratio of the certain width to the width of the entire direction is 1, that is, at least two types of fibers are alternately distributed over the entire width of the entire direction;

[0268] Or, as Figure 11b 、 Figure 11e and Figure 11g As shown, at least two types of fibers are alternately distributed along the warp direction or the weft direction with a certain width, and the ratio range of the certain width to the width of the entire direction includes (0, 1), that is, at least two types of fibers are alternately distributed over a partial width of the entire direction.

[0269] Among them, the embodiments of the present application do not limit the specific structure of at least two types of fibers being alternately distributed along the corresponding direction with a certain width. It may be composed of fibers alternately distributed with a set width or alternately distributed with a plurality of adjacent set widths (such as Figure 11gIt is composed of a set width a and a set width b as shown; it can also be composed of fibers with a set width arranged at intervals and distributed alternately, for example, the fibers with a set width are continuously distributed between adjacent fibers with a set width arranged alternately.

[0270] In addition, the number of types of fibers distributed alternately in the embodiments of the present application is not limited, and it can be two or more (for example, three, four, five or more) types of fibers distributed alternately.

[0271] Moreover, in the fiber body with more than two types of fibers in the embodiments of the present application (for example, the warp fiber body 311 or the weft fiber body 312), at least one type (for example, one, two, three, four, five, six, seven or more types) of fibers can be continuously distributed with a set width along the corresponding direction (i.e., the warp direction S or the weft direction W), and at least two types (for example, two, three, four, five, six, seven or more types) of fibers are distributed alternately along the corresponding direction.

[0272] In addition, when there are more than two types of fibers in one direction (i.e., the warp direction S or the weft direction W) in the embodiments of the present application (for example, Figures 11a to 11c 、 Figure 11g and Figure 11h in the warp fiber body 311, or, as Figures 11d to 11h in the weft fiber body 312), the embodiments of the present application do not limit the distribution of the fibers in the other direction (i.e., the weft direction W or the warp direction S).

[0273] For example, the fibers in the other direction can also be continuously distributed with a set width, or more than two types of fibers are distributed alternately, or more than two types of fibers are respectively continuously distributed with a set width, or more than two types of fibers are both respectively continuously distributed with a set width and alternately distributed with another set width, or among more than two types of fibers, some types of fibers are respectively continuously distributed with a set width, and some other types of fibers are alternately distributed with another set width, etc. In a possible implementation manner, Figure 11i shows a schematic diagram of the structure of another mixed woven fiber layer 3 provided by the embodiments of the present application. Referring to Figure 11i , the number of types and fiber types of the warp fibers 3111 and the weft fibers 3121 in the above-mentioned mixed woven fiber layer 3 can also be: three different types of warp fibers 3111 (i.e., fiber A, fiber C, and fiber B) continuously distributed in sequence along the weft direction W, as Figure 11iAs shown by A, C, and B), and two different types of weft fibers 3121 (i.e., B fibers and D fibers) that are continuously distributed in sequence along the warp direction S. That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes three types of warp fibers 3111, and the weft fiber body 312 includes two types of weft fibers 3121, and the fiber types include four types: A fibers, B fibers, C fibers, and D fibers.

[0274] Specifically, three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) and two types of weft fibers 3121 (i.e., B fibers and D fibers) are mixed and woven along the weft direction W and the warp direction S respectively to form the hybrid woven fiber layer 3. Among them, the A fibers, C fibers, and B fibers are distributed in sequence along the weft direction W, and the B fibers and D fibers are distributed in sequence along the warp direction.

[0275] Thus, the A fibers, B fibers, C fibers, and D fibers together form a hybrid woven fiber layer 3 having a plurality of weaving regions 32, where the plurality of weaving regions 32 include six different weaving regions 32 (such as Figure 11i shown by the A / B region, A / D region, C / B region, C / D region, B / B region, and B / D region in), and the six different weaving regions 32 have different material properties, and further the plurality of different weaving regions 32 can be mapped and corresponded to a plurality of devices of the electronic device 1.

[0276] Exemplarily, the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) or the two types of weft fibers 3121 (i.e., B fibers and D fibers) include organic fibers or inorganic fibers, and the two types of weft fibers 3121 (i.e., B fibers and D fibers) or the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include at least two types of organic fibers; or,

[0277] the two types of weft fibers 3121 (i.e., B fibers and D fibers) or the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include at least two types of organic fibers or inorganic fibers; or,

[0278] the two types of weft fibers 3121 (i.e., B fibers and D fibers) or the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include organic fibers and inorganic fibers.

[0279] In a possible implementation manner, Figure 11j shows a schematic structural diagram of yet another hybrid woven fiber layer 3 provided by the embodiments of the present application. Refer to Figure 11j, the types and quantities of the warp fibers 3111 and weft fibers 3121 in the above-mentioned hybrid woven fiber layer 3 and the fiber types may also be: three different types of warp fibers 3111 (i.e., A fibers, C fibers, and B fibers) continuously distributed along the weft direction W (as shown by A, C, and B in Figure 11j ), and the same type of weft fiber 3121 (i.e., D fibers) continuously distributed in sequence along the warp direction S. That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes three types of warp fibers 3111, the weft fiber body 312 includes one type of weft fiber 3121, and the fiber types include four types: A fibers, B fibers, C fibers, and D fibers.

[0280] Specifically, three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) and one type of weft fiber 3121 (i.e., D fibers) are respectively mixed and woven along the weft direction W and the warp direction S to form the hybrid woven fiber layer 3. Among them, the A fibers, C fibers, and B fibers are distributed in sequence along the weft direction W, and the D fibers are distributed along the warp direction. That is, the D fibers are continuously distributed throughout the warp direction S.

[0281] Thus, the A fibers, B fibers, C fibers, and D fibers together form a hybrid woven fiber layer 3 having a plurality of weaving regions 32, where the plurality of weaving regions 32 include three different weaving regions 32 (as shown by the A / D region, C / D region, and B / D region in Figure 11j ), and the material properties of the three different weaving regions 32 are also different. Furthermore, the plurality of different weaving regions 32 can be mapped and corresponding to a plurality of devices of the electronic device 1.

[0282] Exemplarily, the fiber type of one type of weft fiber 3121 (i.e., D fibers) includes organic fibers or inorganic fibers, and the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include at least two types of organic fibers; or,

[0283] the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include at least two types of organic fibers or inorganic fibers; or,

[0284] the fiber types of the three types of warp fibers 3111 (i.e., A fibers, B fibers, and C fibers) include organic fibers and inorganic fibers.

[0285] In a possible implementation manner, Figure 11k shows a schematic structural diagram of still another hybrid woven fiber layer 3 provided by the embodiment of the present application. Refer to Figure 11k, the types and quantities of the warp fibers 3111 and weft fibers 3121 in the above-mentioned hybrid woven fiber layer 3 can also be: four types of warp fibers 3111 (i.e., A fiber, C fiber, D fiber, and B fiber) continuously distributed in sequence along the weft direction W (as shown by A, C, D, and B in Figure 11a ), and three types of weft fibers 3121 (i.e., A fiber, C fiber, and B fiber) continuously distributed in sequence along the warp direction S (as shown by A, C, and B in Figure 11k ). That is, the warp fiber body 311 of the hybrid woven fiber layer 3 includes four types of warp fibers 3111, and the weft fiber body 312 includes three types of weft fibers 3121. The fiber types include four types: A fiber, B fiber, C fiber, and D fiber.

[0286] Specifically, four types of warp fibers 3111 (i.e., A fiber, B fiber, C fiber, and D fiber) and three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) are respectively mixed and woven along the weft direction W and the warp direction S to form the hybrid woven fiber layer 3. Among them, the A fiber, C fiber, D fiber, and B fiber are distributed in sequence along the weft direction W, and the A fiber, C fiber, and B fiber are distributed in sequence along the warp direction S.

[0287] Thus, the A fiber, B fiber, C fiber, and D fiber jointly form a hybrid woven fiber layer 3 with multiple weaving regions 32. Among them, the multiple weaving regions 32 include nine different weaving regions 32 (as shown by A / A region, A / B region, A / C region, B / A region, B / B region, B / C region, C / A region, C / B region, C / C region, D / A region, D / B region, and D / C region in Figure 11k ). Then, the material properties of the nine different weaving regions 32 are also different. Furthermore, the multiple different weaving regions 32 can be mapped and corresponded to multiple devices of the electronic device 1.

[0288] Exemplarily, the fiber types of the four types of warp fibers 3111 (i.e., A fiber, B fiber, C fiber, and D fiber) or the three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) include organic fibers or inorganic fibers, and the three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) or the four types of warp fibers 3111 (i.e., A fiber, B fiber, C fiber, and D fiber) include at least two types of organic fibers; or,

[0289] the three types of weft fibers 3121 (i.e., A fiber, B fiber, and C fiber) or the four types of warp fibers 3111 (i.e., A fiber, B fiber, C fiber, and D fiber) include at least two types of organic fibers or inorganic fibers; or,

[0290] The three types of weft fibers 3121 (i.e., A fibers, B fibers, and C fibers) or the four types of warp fibers 3111 (i.e., A fibers, B fibers, C fibers, and D fibers) include organic fibers and inorganic fibers.

[0291] In summary, the hybrid woven fiber layer 3 of the embodiment of the present application may include one type of warp fiber 3111 (such as Figure 11d and 11e , Figure 11f as shown in Figures 11a to 11c and Figures 11g to 11k ) or more than two types of warp fibers 3111 (such as Figures 11a to 11c and Figure 11j as shown in Figures 11c to 11i and Figure 11k ), and one type of weft fiber 3121 (such as Figures 11a to 11c and Figure 11j as shown in Figures 11c to 11i and Figure 11k ) or more than two types of weft fibers 3121 (such as Figures 11c to 11i and Figure 11k as shown in

[0292] Moreover, the warp fibers 3111 and the weft fibers 3121 in any of the above embodiments may be organic fibers, or inorganic fibers, or organic fibers and inorganic fibers respectively.

[0293] As Figure 4a shown, the composite material laminated structure of the housing 2 in the embodiment of the present application is prepared by laminating the composite material structure 201 and the single woven fiber layer 202. However, the specific structure of the composite material laminated structure in the embodiment of the present application is not limited. The composite material laminated structure of the housing in some application scenarios will be exemplarily described below with reference to the accompanying drawings.

[0294] In a possible implementation manner, referring to Figure 12a and Figure 12b , Figure 12a shows a schematic structural diagram of a housing 4 provided in another embodiment of the present application, Figure 12b shows an exploded schematic diagram of a three-layer composite material structure 201 provided in another embodiment of the present application. Among them, the housing 4 includes the above-mentioned composite material laminated structure, and the composite material laminated structure includes the above-mentioned composite material structure 201 and the surface treatment layer 203. Among them, the number of the composite material structures 201 includes a plurality.

[0295] Specifically, referring to Figure 12b and combining with Figure 12a , along the lamination direction (i.e., the thickness direction of the housing 4, such as the Z direction shown in Figure 12a and Figure 12b ), the three-layer composite material structures 201 are respectively laminated, and the surface treatment layer 203 is laminated on the uppermost composite material structure 201.

[0296] That is, compared with Figure 4aThe difference of the shown housing 2 is that, as Figure 12a shown, the composite material laminated structure of the housing 4 in the embodiment of the present application not only uses the composite material structure 201 as the core layer, but also uses the composite material structure 201 as the surface layer, so as to obtain a structural member having a positional and dimensional correspondence relationship with the application product (for example, the above-mentioned electronic device 1), and further obtain a final product that meets different performance requirements in different regions, for example, the housing 4 in the embodiment of the present application.

[0297] It should be noted that the embodiment of the present application does not limit the specific structure of the hybrid woven fiber layer 3 of the composite material structure 201 in the composite material laminated structure. The following combines the attached Figures 13a to 14 to exemplarily illustrate the composite material laminated structure of the housing in some application scenarios.

[0298] In a possible implementation manner, as Figure 13a shown, when the multi-layer composite material structure 201 is stacked in sequence, along the stacking direction (as Figure 13a shown by the Z direction in

[0299] ), the positions of the respective weaving regions 32 (for example, the above-mentioned first weaving region 321) of each layer of the composite material structure 201 are the same. That is, the projections of the first weaving region 321 coincide to enhance the material performance of the key region of the housing 4 corresponding to the first weaving region 321. Exemplarily, the fiber types of the first warp fibers and the first weft fibers of the first weaving region 321 both include organic fibers. Figure 13b However, it is not limited thereto. As Figure 13a shown, when the multi-layer composite material structure 201 is stacked in sequence, along the stacking direction (as

[0300] shown by the Z direction in

[0301] Figure 13a ), the positions of the respective weaving regions 32 (for example, the above-mentioned first weaving region 321) of each layer of the composite material structure 201 may also be different. That is, the projections of the first weaving region 321 do not coincide, so as to perform specific staggered laminations according to actual needs, thereby obtaining better comprehensive performance.

[0300] For example, it may also be that the positions of the respective weaving regions 32 of at least two layers of the composite material structure 201 in the multi-layer composite material structure 201 are different, or it may also be that the positions of the first weaving regions 321 of at least two layers of the composite material structure 201 in the multi-layer composite material structure 201 are different, and the positions of the second weaving region and the third weaving region are the same, etc.

[0301] It should be noted that multiple braiding regions in the embodiments of the present application can all correspond to key regions of the housing. For example, it can also be that the second braiding region corresponds to the key region of the housing; or, the third braiding region corresponds to the key region of the housing; or, both the first braiding region and the second braiding region correspond to the key region of the housing; or, both the second braiding region and the third braiding region correspond to the key region of the housing; or, the first braiding region, the second braiding region, and the third braiding region all correspond to the key region of the housing, etc.

[0302] In addition, continuing to refer to Figure 12b , as Figure 12b shown, the three-layer composite material structure 201 all uses the same hybrid braided fiber layer 3, but is not limited thereto. The embodiments of the present application do not specifically limit the selection of fiber types of the hybrid braided fiber layer 3 in the composite material laminated structure.

[0303] In a possible implementation manner, as Figure 14 shown, the three-layer composite material structure 201 uses different hybrid braided fiber layers 3. That is, the fiber types in the hybrid braided fiber layers 3 of any two adjacent composite material structures 201 are different from each other. For example, the hybrid braided fiber layer 3 in the first layer uses a mixture of organic fibers and inorganic fibers, the hybrid braided fiber layer 3 in the second layer uses a mixture of different types of organic fibers and organic fibers, and the hybrid braided fiber layer 3 in the third layer uses a mixture of different types of inorganic fibers and inorganic fibers, etc. It should be noted that, as described above, the embodiments of the present application do not limit the number of fiber types for hybrid braiding, for example, it can be two or more.

[0304] In summary, the embodiments of the present application perform hybrid braiding with fibers of different fiber types to form a mixed braided fabric (i.e., the hybrid braided fiber layer 3) having at least two braiding regions, and use the mixed braided fabric as a laminated material to prepare a final product with different performances in each region (such as the above-mentioned housing 2).

[0305] On the one hand, the composite material structure 201 of the embodiments of the present application forms braiding regions 32 with different material performances through hybrid braiding, which can enable the composite material structure 201 to meet the different material performance requirements of different regions of the housing 2 for different components of the electronic device 1 in the embodiments of the present application.

[0306] On the other hand, the composite material structure 201 is mixed and woven with continuous fibers, so that the fibers are continuous between different weaving regions 32, and thus the inner surfaces between the weaving regions 32 of the composite material structure 201 are continuous without interruption, improving the overall mechanical properties of the composite material structure 201, and further improving the overall mechanical properties of the housing 2. In addition, in the embodiments of the present application, through the mixed weaving of organic fibers and inorganic fibers, the usage amount of organic fibers is reduced and the utilization rate is high, effectively reducing the production cost.
