Detailed implementation manners

[0063] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present disclosure.

[0064] The terms used herein are merely for describing specific embodiments and are not intended to limit the present disclosure. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0065] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0066] An electronic device generally has a cover plate for protecting the components inside the electronic device. For example, a mobile phone includes a middle frame, a display screen, and a cover plate, etc. The display screen and the cover plate are located on opposite sides of the middle frame. The cover plate generally needs to have good drop resistance, touch feeling, and aesthetics.

[0067] In the related art, the cover plate can be prepared from two materials, and the two materials include a hard material and a soft material. For example, the cover plate is made of a combination of a glass fiber board and a leatherette. To improve the aesthetics, the leatherette is usually composed of two or more leatherette boards spliced together. First, a glass fiber board with a target thickness is prepared by a hot pressing process. According to the number and splicing positions of the leatherette boards, positioning strips matching the number and splicing positions of the leatherette boards need to be formed on the glass fiber board. Multiple leatherette boards are adhered to one surface of the glass fiber board through hot melt adhesive. During the process of adhering the leatherette boards, the positions of the leatherette boards are positioned by the positioning strips. The bonding process is mostly completed manually. The positioning strips are located between two adjacent leatherette boards. Affected by the error of manual operation, gaps will inevitably appear at the docking positions of the two leatherette boards, and the widths of the gaps are likely to be inconsistent, resulting in poor splicing consistency and affecting the overall aesthetics. There are positioning strips between two adjacent leatherette boards, and the materials of the positioning strips and the leatherette boards are different, resulting in inconsistent touch feelings; in addition, multiple leatherette boards are adhered manually, resulting in low preparation efficiency of the cover plate.

[0068] To solve the above problems, the present disclosure provides an electronic device and a preparation method.

[0069] The following combines Figures 1 to 13 to describe the electronic device and the preparation method of the present disclosure.

[0070] In the embodiments of the present disclosure, as Figures 1 to 3As shown, the electronic device includes a cover plate, and the cover plate includes adjacent first leather layer 11 and second leather layer 12. The first leather layer 11 and the second leather layer 12 are connected to present target parameters. Among them, the first appearance surface of the first leather layer 11 presents a first parameter, and the second appearance surface of the second leather layer 12 presents a second parameter. Based on the integral molding of the first leather layer 11 and the second leather layer 12, the adjacent connection part of the first leather layer 11 and the second leather layer 12 meets the coplanar condition. The first parameter and the second parameter are different to distinguish the first appearance surface and the second appearance surface.

[0071] The electronic device includes mobile phones, tablet computers, laptop computers, etc. According to different usage scenarios, the cover plate can be composed of a composite of a fiberglass board and a leather material, or the cover plate can also be prepared only from a leather material.

[0072] In some embodiments, the cover plate can be composed of a composite of a fiberglass board and a leather board. The fiberglass board is defined as the inner layer board, and the leather board is defined as the outer layer board. The fiberglass board ensures that the cover plate has appropriate hardness, and the leather board ensures that the cover plate has better touch and aesthetics.

[0073] The outer layer board is spliced by multiple leather layers. The number of leather layers is not specifically limited, and the number of leather layers can be two or more. The multiple leather layers can be initially shaped by a pressing process and then integrally formed by a hot pressing process.

[0074] When the number of leather layers is two, the two leather layers are defined as the first leather layer 11 and the second leather layer 12 respectively.

[0075] The first appearance surface of the first leather layer 11 presents a first parameter, that is, the first appearance surface has a first visual effect, and the first visual effect is reflected by color, pattern, texture, geometric shape, etc. The second appearance surface of the second leather layer 12 presents a second parameter, that is, the second appearance surface has a second visual effect, and the second visual effect is reflected by color, pattern, texture, geometric shape, etc. The first parameter and the second parameter are different to distinguish the first appearance surface and the second appearance surface. The appearance surface of the cover plate presents the visual effect brought by the combination of the first appearance surface and the second appearance surface.

[0076] For example, the colors of the first parameter and the second parameter are different. The first appearance surface can present a rose red color, and the second appearance surface can present an orange color. The appearance surface of the cover plate presents the target parameter, that is, the appearance surface of the cover plate presents the visual effect brought by the combination of the two colors, avoiding the monotony brought by one color to the user.

[0077] For example, the patterns of the first parameter and the second parameter are different. The first appearance surface can present a first pattern related to the spring scenery, and the second appearance surface can present a second pattern related to the winter scenery. The appearance surface of the cover plate presents the target parameter, that is, the appearance surface of the cover plate presents the visual effect brought by the combination of the two patterns.

[0078] For example, the textures of the first parameter and the second parameter are different. The texture density of the first appearance surface is smaller, and the texture is finer. The texture density of the second appearance surface is larger, and the texture is more grand. The appearance surface of the cover plate presents the target parameter, that is, the appearance surface of the cover plate presents the visual effects brought by the two patterns.

[0079] It can be understood that when the number of leather layers is multiple, the appearance surface of the cover plate can present the visual effects brought by the combination of three or more colors, or the visual effects brought by the combination of three or more patterns, or the visual effects brought by the combination of three or more textures, or the visual effects brought by the combination of multiple colors, multiple patterns, multiple textures, and multiple geometric shapes. The overall appearance surface of the cover plate is composed of the combination of multiple different appearance surfaces of multiple leather layers, which can provide users with diverse visual experiences.

[0080] In some embodiments, the first leather layer 11 and the second leather layer 12 have the same thickness and the same width dimension. The length dimensions can be the same or different. The splicing direction is consistent with the length direction of the cover plate, and the first leather layer 11 and the second leather layer 12 are sequentially placed along the splicing direction. The first leather layer 11 and the second leather layer 12 are pressed through a pressing process to form a pressed part; then, through a hot pressing process, the first leather layer 11 and the second leather layer 12 are integrally formed. The first leather layer 11 has a first end face facing the second leather layer 12, and the second leather layer 12 has a second end face facing the first leather layer 11. The connection between the first leather layer 11 and the second leather layer 12 satisfies the coplanar condition, that is, along the thickness direction of the cover plate, there is no up-and-down misalignment between the first end face and the second end face, thereby ensuring the consistency of the touch. It can be understood that the first leather layer 11 and the second leather layer 12 can also be integrally formed by ultrasonic welding. An ultrasonic leather welding machine is used to select appropriate welding parameters, such as frequency, amplitude, etc., to perform ultrasonic welding on the splicing part of the first leather layer 11 and the second leather layer 12.

[0081] In some embodiments, the first leather layer 11 and the second leather layer 12 have the same thickness and the same length dimension, and the width dimensions may be the same or may not be the same. The splicing direction is consistent with the width direction of the cover plate, and the first leather layer 11 and the second leather layer 12 are sequentially placed along the splicing direction. The first leather layer 11 and the second leather layer 12 are pressed together through a pressing process to form a pressed part; then the first leather layer 11 and the second leather layer 12 are integrally formed through a hot pressing process. The first leather layer 11 has a first end face facing the second leather layer 12, and the second leather layer 12 has a second end face facing the first leather layer 11. The connection between the first leather layer 11 and the second leather layer 12 satisfies the coplanar condition, that is, along the thickness direction of the cover plate, the first end face and the second end face do not show an up-and-down dislocation phenomenon, thereby ensuring the consistency of the touch feeling.

[0082] As Figure 2 and Figure 3 shown, in some embodiments, the number of leather layers is three, and the three leather layers are defined as the first leather layer 11, the second leather layer 12, and the third leather layer 13 respectively. The first leather layer 11, the second leather layer 12, and the third leather layer 13 have the same thickness and the same width dimension, and the length dimensions may be the same or may not be the same. The splicing direction is consistent with the length direction of the cover plate, and the first leather layer 11, the third leather layer 13, and the second leather layer 12 are sequentially placed along the splicing direction. The first leather layer 11, the second leather layer 12, and the third leather layer 13 are integrally formed through a pressing process and a hot pressing process in sequence. The first leather layer 11 has a first end face 111 facing the third leather layer 13; the third leather layer 13 has a second end face 131 facing the first leather layer 11 and a third end face 132 facing the second leather layer 12; the second leather layer 12 has a fourth end face 121 facing the third leather layer 13. It can be understood that the first leather layer 11, the second leather layer 12, and the third leather layer 13 can also be integrally formed by ultrasonic welding. An ultrasonic leather welding machine is used to select appropriate welding parameters, such as frequency, amplitude, etc., to perform ultrasonic welding on the splicing joints of the first leather layer 11 and the third leather layer 12 and the third leather layer 12 and the second leather layer 12.

[0083] As Figure 6B shown, the connection between the first leather layer 11 and the third leather layer 13 is defined as the first docking part 31, and the connection between the third leather layer 13 and the second leather layer 12 is defined as the second docking part 32. The first docking part 31 and the second docking part 32 satisfy the coplanar condition, that is, along the thickness direction of the cover plate, the first end face 111, the second end face 131, the third end face 132, and the fourth end face 121 do not show an up-and-down dislocation phenomenon, thereby ensuring the consistency of the touch feeling.

[0084] In some embodiments, the number of leather layers is four, and the four leather layers are defined as a first leather layer 11, a second leather layer 12, a third leather layer 13, and a fourth leather layer. The first leather layer 11, the second leather layer 12, the third leather layer 13, and the fourth leather layer have the same thickness, the same width, and the same or different lengths. The splicing direction is consistent with the length direction of the cover plate, and the first leather layer 11, the second leather layer 12, the third leather layer 13, and the fourth leather layer are placed in sequence along the splicing direction. The first leather layer 11, the second leather layer 12, the third leather layer 13, and the fourth leather layer are formed in one piece by a lamination process and a hot pressing process. The first leather layer 11 has a first end face facing the second leather layer 12; the second leather layer 12 has a second end face facing the first leather layer 11 and a third end face facing the third leather layer 13; the third leather layer 13 has a fourth end face facing the second leather layer 12 and a fifth end face facing the fourth leather layer; the fourth leather layer has a sixth end face facing the third leather layer 13.

[0085] The connection between the third leather layer 13 and the fourth leather layer is defined as the third docking portion, and the first docking portion 31, the second docking portion 32 and the third docking portion meet the coplanar condition, that is, along the thickness direction of the cover plate, the first end face, the second end face, the third end face, the fourth end face, the fifth end face and the sixth end face have no up and down misalignment phenomenon, thereby ensuring the consistency of the touch.

[0086] In an embodiment of the present disclosure, a cover plate of an electronic device includes a first leather layer 11 and a second leather layer 12 adjacent to each other. The parameters of the first appearance surface and the second appearance surface are different, so that the appearance surface of the cover plate can provide diverse visual experiences. The adjacent connections between the first leather layer 11 and the second leather layer 12 meet the coplanar condition, which can ensure the consistency of the touch and improve the comfort of holding, thereby helping to improve the user experience.

[0087] In the embodiments of the present disclosure, Figure 1 , Figure 3 , Figure 4A , Figure 4B As shown in FIG. 6A and FIG. 6B, the adjacent first leather layer 11 and the second leather layer 12 are arranged with their opposite end faces in contact, and the joints of the first leather layer 11 and the second leather layer 12 are interwoven and connected to each other, so that the joints of the first appearance surface and the second appearance surface meet the coplanar condition and have a seamless splicing effect. It can be understood that in FIG. 4B and FIG. 6B, the interwoven structure at the joint is only a schematic diagram.

[0088] In some embodiments, Figure 4A and Figure 4BAs shown, the cover plate includes a first leather layer 11 and a second leather layer 12. In the pressing process, the first end face of the first leather layer 11 is bonded to the second end face of the second leather layer 12. No positioning strip is provided between the first leather layer 11 and the second leather layer 12, and then the first leather layer 11 and the second leather layer 12 are integrally formed through a hot pressing process. As Figure 4B shown, the fiber structures at the first end face of the first leather layer 11 and the second end face of the second leather layer 12 are intertwined and connected to form a first docking part 31.

[0089] According to the geometric shapes of the first leather layer 11 and the second leather layer 12, the first leather layer 11 and the second leather layer 12 can have various splicing methods. As Figure 5A shown, the first leather layer 11 and the second leather layer 12 are spliced along the vertical direction. As Figure 5B shown, the first leather layer 11 and the second leather layer 12 are spliced along the horizontal direction. As Figure 5C shown, the first leather layer 11 and the second leather layer 12 are diagonally spliced. As Figure 5D shown, the locus line at the splicing part of the first leather layer 11 and the second leather layer 12 is wavy. As Figure 5E shown, the locus line at the splicing part of the first leather layer 11 and the second leather layer 12 is L-shaped folded line.

[0090] The first docking part 31 meets the coplanar condition, that is, the connection between the first appearance surface and the second appearance surface meets the coplanar condition, and there is no up-down dislocation or left-right dislocation between the first end face and the second end face. In addition, there is no splicing gap or the splicing gap is close to zero at the first docking part 31, and the first docking part 31 presents a seamless splicing effect.

[0091] As Figure 2 、 Figure 3 、 Figure 6A and Figure 6BAs shown, in some embodiments, the cover plate includes a first leather layer 11, a second leather layer 12, and a third leather layer 13, and the third leather layer 13 is located between the first leather layer 11 and the second leather layer 12. In the lamination process, the first end face 111 of the first leather layer 11 is bonded to the second end face 131 of the third leather layer 13, and the third end face 132 of the third leather layer 13 is bonded to the fourth end face 121 of the second leather layer 12. No positioning strip is provided between the first leather layer 11 and the third leather layer 13, and no positioning strip is provided between the third leather layer 13 and the second leather layer 12. Then, through the hot pressing process, the first leather layer 11, the third leather layer 13, and the second leather layer 12 are integrally formed. The fiber structures at the first end face 111 of the first leather layer 11 and the second end face 131 of the third leather layer 13 are intertwined and connected to form a first docking part 31. The fiber structures at the third end face 132 of the third leather layer 13 and the fourth end face 121 of the second leather layer 12 are intertwined and connected to form a second docking part 32.

[0092] The first docking part 31 and the second docking part 32 meet the coplanar condition, that is, the connection between the first appearance surface and the third appearance surface and the connection between the third appearance surface and the second appearance surface meet the coplanar condition. There is no splicing gap or the splicing gap is close to zero at both the first docking part 31 and the second docking part 32, and both the first docking part 31 and the second docking part 32 present a seamless splicing effect.

[0093] It can be understood that when the number of leather layers is multiple, the opposite end faces of any two adjacent leather layers are bonded, and the fiber structures at the opposite end faces of the two adjacent leather layers are intertwined and connected. Multiple leather layers are connected to form multiple docking parts. The multiple docking parts meet the coplanar condition, and any docking part has a seamless splicing effect. By splicing leather layers with different parameters together, the gap at the splicing part is hardly visible, thereby making the appearance surface of the cover plate present a continuous, complete, and natural appearance effect.

[0094] The docking part has a seamless splicing effect, which can effectively prevent external impurities from infiltrating into the cover plate through the docking part, causing problems such as difficult cleaning and affecting the service life. External impurities include sweat stains, oil stains, etc. When external impurities infiltrate into the cover plate, it not only affects the service life of the cover plate but also damages the components inside the electronic device. In addition, the seamless splicing effect ensures the consistency of the splicing effect, further improving the touch and aesthetics of the cover plate. The intertwined connection of the fiber structures at the splicing part makes the leather at the splicing part more evenly stressed in all directions, thereby enhancing the overall tear resistance of the leather and reducing the possibility of deformation or damage caused by local stress, which is beneficial to improving the service life of the cover plate.

[0095] In an embodiment of the present disclosure, the fiber structures at the opposite end faces of the adjacent first leather layer 11 and second leather layer 12 are intertwined and connected, so that the first appearance surface and the second appearance surface meet the coplanar condition and have a seamless splicing effect, which is beneficial to further improving the touch and aesthetics of the cover plate. In addition, it can prevent external impurities from penetrating into the cover plate, which is beneficial to improving the service life of the cover plate and the electronic device; the fiber structures at the splicing part are intertwined and connected, enhancing the overall tear resistance of the leather, which is beneficial to improving the service life of the cover plate.

[0096] In an embodiment of the present disclosure, the target parameters include at least one of color parameters, pattern parameters, texture parameters, and geometric parameters. The target parameters include a first parameter and a second parameter, and the first leather layer 11 and the second leather layer 12 are connected to make the cover plate have a preset visual effect.

[0114] In an embodiment of the present disclosure, the cover plate is formed by an inner layer board 20 with a preset hardness and multiple leather layers connected to the same side of the inner layer board 20. Multiple leather layers form multiple docking portions. The multiple docking portions satisfy the coplanar condition and have a seamless splicing effect, which not only ensures that the cover plate has advantages such as drop resistance and wear resistance, but also improves the aesthetics, holding comfort, and durability of the cover plate.

The first docking portion 31 and the second docking portion 32 satisfy the coplanar condition, and both the first docking portion 31 and the second docking portion 32 have a seamless splicing effect.

[0120] The second leather layer 12 is planar, and the first leather layer 11 is provided with a collection area 113 corresponding to the collection module of the electronic device. The collection module includes a camera, and the number of cameras is set according to actual needs, and the number of cameras is one, two, three, four, etc. Limited by the thickness of the electronic device, the collection area 113 protrudes from the second leather layer 12. The collection area 113 has a plurality of through holes 1131, and the number of through holes 1131 is the same as the number of cameras. The through holes 1131 are used to expose the cameras. For example, when the number of cameras is four, the collection area 113 is provided with four through holes 1131, and the aperture of the through holes 1131 is adapted to the radial dimension of the cameras.

[0121] It can be understood that when the cover plate is composed of the inner layer plate 20 and the outer layer plate 10, the inner layer plate 20 has a collection area conformal to the collection area 113 of the first leather layer 11. The through holes 1131 penetrate through the first leather layer 11 and the inner layer plate 20.

[0122] The first leather layer 11 is provided with a collection area 113 protruding relative to the second leather layer 12, so that the thickness of most areas of the cover plate is relatively thin, and only the thickness is large in the area corresponding to the collection module, which not only meets the installation requirements of the collection module, but also is beneficial to the overall thinness and lightness of the electronic device.

[0123] In some embodiments, the length dimension of the first leather layer 11 is greater than the length dimension of the second leather layer 12, and the length dimension of the second leather layer 12 is greater than the length dimension of the third leather layer 13.

During assembly, first install the acquisition module on the frame structure of the housing, then place the cover plate on one side of the housing. Multiple cameras of the acquisition module are respectively exposed from multiple through holes 1131 in the acquisition area 113 of the first leather layer 11, and then fix the cover plate to the housing. The cover plate and the housing can be fixedly connected by glue.

[0126] In an embodiment of the present disclosure, the first leather layer 11, the second leather layer 12, and the third leather layer 13 are spliced to form the outer layer plate 10 of the cover plate, so that the appearance surface of the cover plate has a diverse visual experience; the first leather layer 11 is provided with an acquisition area 113 protruding relative to the second leather layer 12, so that the thickness of most areas of the cover plate is relatively thin, and only the thickness is relatively large in the area corresponding to the acquisition module, which not only meets the installation requirements of the acquisition module, but also is beneficial to the thin and light of the electronic device.

[0127] As Figure 13 shown, the present disclosure also provides a preparation method, and the preparation method includes:

[0128] Step 110: Obtain a cover plate workpiece, and the cover plate workpiece includes a first leather layer 11 and a second leather layer 12;

[0129] Step 120: Connect the first leather layer 11 and the second leather layer 12 based on a first process to present target parameters. Among them, the first appearance surface of the first leather layer 11 presents a first parameter, and the second appearance surface of the second leather layer 12 presents a second parameter;

[0130] Step 130: Integrally form the first leather layer 11 and the second leather layer 12 based on a second process so that the adjacent connection parts of the first leather layer 11 and the second leather layer 12 meet the coplanar condition;

[0131] Among them, the first parameter is different from the second parameter to distinguish the first appearance surface and the second appearance surface.

[0132] Obtain at least two different leather parts, define the two different leather parts as a first leather part and a second leather part respectively. The first leather part and the second leather part have the same thickness, and at least one of the color, pattern, and texture of the first leather part and the second leather part is different.

[0133] As Figure 8 shown, through a cutting process, the first leather layer 11 can be cut out on the first leather part, and the second leather layer 12 can be cut out on the second leather part. The cover plate workpiece includes the first leather layer 11 and the second leather layer 12.

[0134] In some embodiments, the first appearance surface of the first leather layer 11 may exhibit a rosy red color, and the second appearance surface of the second leather layer 12 may exhibit an orange color. The width dimensions of the first leather layer 11 and the second leather layer 12 may be the same, and the length dimension of the first leather layer 11 is greater than the length dimension of the second leather layer 12.

[0135] The first process includes a pressing process, and a press may be used to press the first leather layer 11 and the second leather layer 12. The first leather layer 11 and the second leather layer 12 are paired along the splicing direction, and the first end face of the first leather layer 11 is attached to the second end face of the second leather layer 12. After the first leather layer 11 and the second leather layer 12 are pressed, a pressed part is formed, and no positioning strip is provided between the first leather layer 11 and the second leather layer 12.

[0136] The second process includes a hot pressing process, and a hot pressing device is used to hot press and form the pressed part. During the hot pressing and forming process, the fiber structures at the first end face of the first leather layer 11 and the fiber structures at the second end face of the second leather layer 12 are intertwined and connected to each other. After being processed by the hot pressing process, the first leather layer 11 and the second leather layer 12 are integrally formed, and a butt joint part is formed at the joint of the first leather layer 11 and the second leather layer 12. Along the length direction of the butt joint part, any position of the butt joint part satisfies the coplanar condition, that is, there is no up and down dislocation between the first end face and the second end face in the thickness direction, thereby enabling the cover plate to have a better touch and being beneficial to improving the comfort of the user's grip.

[0137] There is no need to provide a positioning strip between the first leather layer 11 and the second leather layer 12 to ensure the consistency of the overall touch of the cover plate. By the hot pressing process, the first leather layer 11 and the second leather layer 12 are integrally formed, which can effectively avoid the phenomenon of uneven splicing gaps between the first leather layer 11 and the second leather layer 12 caused by manual bonding, ensure the consistency of the splicing effect at the splicing of the first leather layer 11 and the second leather layer 12, and further be beneficial to improving the aesthetics of the cover plate.

[0138] By the first process, the first leather layer 11 and the second leather layer 12 are preliminarily positioned, and then by the second process, the first leather layer 11 and the second leather layer 12 are integrally formed. Compared with the manual operation of sequentially bonding the first leather layer 11 and the second leather layer 12 to a substrate with a positioning strip, the consistency of the splicing effect can be effectively improved, the preparation efficiency can be improved. In addition, no adhesive is required during the preparation process, which is beneficial to reducing the preparation cost.

[0139] Such as Figure 8As shown, in some embodiments, the cover plate workpiece includes a first leather layer 11, a second leather layer 12, and a third leather layer 13. The first appearance surface of the first leather layer 11 may present a rose red color, the second appearance surface of the second leather layer 12 may present an orange color, and the third appearance surface of the third leather layer 13 may present a yellow color. The width dimensions of the first leather layer 11, the second leather layer 12, and the third leather layer 13 may be the same. The length dimension of the first leather layer 11 is greater than the length dimension of the second leather layer 12, and the length dimension of the second leather layer 12 is greater than the length dimension of the third leather layer 13.

[0140] Place the first leather layer 11, the third leather layer 13, and the second leather layer 12 in sequence along the splicing direction, and form a pressed part through a pressing process. No positioning strips are provided between the first leather layer 11 and the third leather layer 13, and between the third leather layer 13 and the second leather layer 12.

[0141] Perform hot pressing on the pressed part through a hot pressing process. During the hot pressing process, the fiber structures at the first end face 111 of the first leather layer 11 and the second end face 131 of the third leather layer 13 are intertwined and connected with each other, and the fiber structures at the third end face 132 of the third leather layer 13 and the fourth end face 121 of the second leather layer 12 are intertwined and connected with each other. After being processed by the hot pressing process, the first leather layer 11, the second leather layer 12, and the third leather layer 13 are integrally formed. A first docking part 31 is formed at the connection between the first leather layer 11 and the third leather layer 13, and a second docking part 32 is formed at the connection between the third leather layer 13 and the second leather layer 12. The first docking part 31 and the second docking part 32 meet the coplanar condition, that is, there is no up and down misalignment between the first end face 111, the second end face 131, the third end face 132, and the fourth end face 121 in the thickness direction.

[0142] In the embodiments of the present disclosure, the first leather layer 11 and the second leather layer 12 are preliminarily positioned through the first process, and then the first leather layer 11 and the second leather layer 12 are integrally formed through the second process. Compared with the manual operation of sequentially bonding the first leather layer 11 and the second leather layer 12 to a substrate with positioning strips, the consistency of the splicing effect at the splicing joint can be effectively improved, and the preparation efficiency can be improved. In addition, no binder is required during the forming process, which is beneficial to reducing the preparation cost.

[0143] In the embodiments of the present disclosure, connecting the first leather layer 11 and the second leather layer 12 based on the first process for presenting target parameters includes:

[0144] Obtain the first leather layer 11 and the second leather layer 12 with a preset shape;

[0145] Place the first leather layer 11 and the second leather layer 12 along the splicing direction in the first mold 50;

[0146] Place the release film 40 on the same side of the first leather layer 11 and the second leather layer 12;

[0147] Through the first process, press and bond the first leather layer 11, the second leather layer 12 and the release film 40, so that the first leather layer 11 and the second leather layer 12 are separably connected to the release film 40;

[0148] Wherein, the first leather layer 11 and the second leather layer 12 form a butt joint part, the butt joint part meets the coplanarity condition, and the splicing gap of the butt joint part meets the preset condition.

[0149] In some embodiments, the cover workpiece includes a first leather layer 11 and a second leather layer 12. The first leather layer 11 with a preset shape can be cut out on the first leather piece through a cutting process, and the second leather layer 12 with a preset shape can be cut out on the second leather workpiece. The first leather layer 11 and the second leather layer 12 can both be square shapes.

[0150] As Figure 10 shown, the press includes a first mold 50, and the first mold 50 has an upper mold and a lower mold. Place the first leather layer 11 and the second leather layer 12 on the lower mold of the first mold 50 along the splicing direction, and the first end face of the first leather layer 11 and the second end face of the second leather layer 12 are attached to each other. Place the release film 40 above the first leather layer 11 and the second leather layer 12, and then the lower mold and the upper mold are pressed together to press and bond the first leather layer 11, the second leather layer 12 and the release film 40 to form a pressed part. As Figure 9 shown, the first leather layer 11 and the second leather layer 12 adhere to the release film 40 based on pressure. It can be understood that by applying a certain tearing force to the release film 40, the release film 40 can be separated from the first leather layer 11 and the second leather layer 12.

[0151] Through the pressing process, the first leather layer 11 and the second leather layer 12 are preliminarily positioned. There is no need to set a positioning strip between the first leather layer 11 and the second leather layer 12 to ensure the consistency of the touch at the butt joint part of the first leather layer 11 and the second leather layer 12. The release film 40 can both adhere to the first leather layer 11 and the second leather layer 12 and be separated from the first leather layer 11 and the second leather layer 12.

[0152] In some embodiments, the cover workpiece includes a first leather layer 11, a second leather layer 12 and a third leather layer 13. As Figure 8 shown, the first leather layer 11 with a preset shape is cut out on the first leather piece through a cutting process, the second leather layer 12 with a preset shape is cut out on the second leather piece, and the third leather layer 13 with a preset shape is cut out on the third leather piece. The first leather layer 11, the second leather layer 12 and the third leather layer 13 can all be square shapes.

[0153] As Figure 2 、 Figure 3 and Figure 10 shown, along the splicing direction, the first leather layer 11, the third leather layer 13 and the second leather layer 12 are placed on the lower mold of the first mold 50. The first end face 111 of the first leather layer 11 is attached to the second end face 131 of the third leather layer 13, and the third end face 132 of the third leather layer 13 is attached to the fourth end face 121 of the second leather layer 12. A release film 40 is placed above the first leather layer 11, the third leather layer 13 and the second leather layer 12, and then the lower mold and the upper mold are pressed together to press the first leather layer 11, the third leather layer 13, the second leather layer 12 and the release film 40 to form a pressed part. As Figure 7 shown, the first leather layer 11, the third leather layer 13 and the second leather layer 12 adhere to the release film 40 based on pressure. It can be understood that by applying a certain tearing force to the release film 40, the release film 40 can be separated from the first leather layer 11, the third leather layer 13 and the second leather layer 12.

[0154] The first leather layer 11, the third leather layer 13 and the second leather layer 12 are preliminarily positioned through the pressing process. There is no need to set a positioning strip between the first leather layer 11 and the third leather layer 13 to ensure the coplanarity of the first docking part 31 of the first leather layer 11 and the third leather layer 13 and the consistency of the splicing gap; there is no need to set a positioning strip between the third leather layer 13 and the second leather layer 12 to ensure the coplanarity of the second docking part 32 of the third leather layer 13 and the second leather layer 12 and the consistency of the splicing gap. The release film 40 can both adhere to the first leather layer 11, the third leather layer 13 and the second leather layer 12 and be separated from the first leather layer 11, the third leather layer 13 and the second leather layer 12.

[0155] In the embodiments of the present disclosure, the first leather layer 11 and the second leather layer 12 are placed on the first mold 50 along the splicing direction, and then the release film 40 is placed on the same side of the first leather layer 11 and the second leather layer 12. Based on pressure, the release film 40 can adhere to the first leather layer 11 and the second leather layer 12, and the release film 40 can be separated from the first leather layer 11 and the second leather layer 12 under a certain tearing force, which can not only ensure the coplanarity at the docking part and the consistency of the splicing gap, but also the release film 40 has a low cost, which is beneficial to reducing the preparation cost. When the release film 40 is separated, the different leather layers are still connected in an intertwined manner and can maintain a certain degree of freedom and flexibility, so that the leather can naturally conform to the movement when bending and folding, and maintain the integrity and durability of its connection as the release film 40 is separated.

[0156] In the embodiments of the present disclosure, before placing the first leather layer 11 and the second leather layer 12 on the first mold 50 along the splicing direction, it further includes:

[0157] Positioning holes are processed on the first leather layer 11 and the second leather layer 12 respectively. The first mold 50 has a plurality of positioning members adapted to the positioning holes.

Tools such as a leather cutting knife, an art knife, or a special leather scissors are used to cut out the first leather layer 11, the second leather layer 12, and the third leather layer 13 with a preset shape. The first leather layer 11, the second leather layer 12, and the third leather layer 13 can all be square-shaped. The length dimensions of the first leather layer 11 and the second leather layer 12 are greater than the length dimension of the third leather layer 13.

[0164] In an embodiment of the present disclosure, the first leather layer 11 and the second leather layer 12 are provided with positioning holes, and the plurality of positioning members of the first mold 50 pass through the plurality of positioning holes of the first leather layer 11 and the second leather layer 12. During the pressing process, the offset of the first leather layer 11 and the second leather layer 12 can be effectively avoided, and the consistency of the splicing gaps at the docking parts can be ensured.

[0165] In an embodiment of the present disclosure, the integral molding of the first leather layer 11 and the second leather layer 12 based on the second process to make the adjacent connection parts of the first leather layer 11 and the second leather layer 12 meet the coplanar condition includes:

[0166] Obtain a plurality of inner layer boards 21;

[0167] Stack the plurality of inner layer boards 21, the first leather layer 11 and the second leather layer 12 that meet the coplanar condition;

[0168] Select a hot pressing process to make the plurality of inner layer boards 21, the first leather layer 11 and the second leather layer 12 form a first blank part, the plurality of inner layer boards 21 form the inner layer board 20, and the inner layer board 20 and the first leather layer 11 form a collection area 113 corresponding to the collection module of the electronic device;

[0169] Among them, the inner layer board 20 is made of a hard material, and the first leather layer 11 and the second leather layer 12 are both made of a soft material.

[0170] The cover plate further includes an inner layer board 20, and the inner layer board 20 includes a plurality of inner layer boards 21 arranged in layers. The material of the inner layer board 21 includes fiberglass material. The number of the inner layer boards 21 is set according to actual needs. The soft material includes silicone leather, environmentally friendly vegan leather materials, etc.

[0171] In some embodiments, the pressed part formed by the pressing process includes a coplanar first leather layer 11, a second leather layer 12 and a third leather layer 13. Such as Figure 11As shown, a plurality of inner layer plates 21 and pressing components are stacked on the second mold 60 of the hot pressing device. Through the hot pressing process, the plurality of inner layer plates 21 and the pressing components form a first blank. The first blank can be a 2D structure, a 2.5D structure, or a 3D structure.

[0172] The process parameters of the hot pressing process include temperature, pressure, and hot pressing duration. The temperature, pressure, and hot pressing duration are set according to actual requirements. For example, the temperature ranges from 110 to 140 degrees Celsius; the pressure ranges from 0 to 40 tons; the hot pressing duration ranges from 400 to 600 seconds.

[0173] In some embodiments, the hot pressing process is carried out in four stages. In the first stage, the pressure is 0, the hot pressing duration is 10 to 20 seconds, and the temperature is 120 to 130 degrees Celsius; in the second stage, the pressure is 0, the hot pressing duration is 5 to 10 seconds, and the temperature is 120 to 130 degrees Celsius; in the third stage, the pressure is 20 to 25 tons, the hot pressing duration is 5 to 10 seconds, and the temperature is 120 to 130 degrees Celsius; in the fourth stage, the pressure is 20 to 25 tons, the hot pressing duration is 350 to 450 seconds, and the temperature is 120 to 130 degrees Celsius. The pressure, hot pressing duration, and temperature in each stage are related to parameters such as the thickness and material of the cover plate.

[0174] After hot pressing and curing, as Figure 7 shown, the plurality of inner layer plates 21 form an inner layer plate 20 with a preset hardness, ensuring that the cover plate has good drop resistance, abrasion resistance, corrosion resistance, etc. Compared with the bonding process, the first leather layer 11, the second leather layer 12, and the third leather layer 13 all have better bonding strength with the inner layer plate 20, improving the bonding strength between the outer layer plate 10 and the inner layer plate 20, and thus extending the service life of the cover plate. In addition, compared with first hot pressing and curing the plurality of inner layer plates 21 to form the inner layer plate 20, and then sequentially bonding the first leather layer 11, the second leather layer 12, and the third leather layer 13 to the inner layer plate 20, in the preparation method of the present disclosure, the plurality of inner layer plates 21, the first leather layer 11, the second leather layer 12, and the third leather layer 13 are integrally formed by the hot pressing process, effectively improving the preparation efficiency and at the same time helping to reduce the preparation cost.

[0175] In some embodiments, the electronic device includes a collection module, and the collection module includes a plurality of cameras. The number of cameras is set according to actual requirements. For example, the number of cameras is four.

[0176] It can be understood that the second mold 60 has a shape adapted to the collection area 113. After the plurality of inner layer plates 21 and the pressing components stacked are hot pressed and formed, a first blank is formed.

[0177] The first blank includes an inner layer plate 20 and an outer layer plate 10. As Figure 1As shown, a collection area 113 protruding from the second leather layer 12 is formed in the area corresponding to the collection module on the first leather layer 11 of the inner layer board 20 and the outer layer board 10. The collection area 113 protrudes relative to other leather layers, making the thickness of most areas of the cover plate relatively thin, and only the thickness is larger in the area corresponding to the collection module. This not only meets the installation requirements of the collection module but also facilitates the thinning of the electronic device.

[0178] Compared with punching out the collection area 113 from the inner layer board 20 and the first leather layer 11 respectively and then bonding multiple leather layers to the inner layer board 20, in the preparation method of the present disclosure, the collection areas 113 of the inner layer board 20 and the first leather layer 11 are formed in one step by a hot pressing process, which can effectively ensure the position accuracy of the collection area 113 on the cover plate.

[0179] In the embodiment of the present disclosure, multiple inner layer plates 21 and the pressing parts are integrally formed by a hot pressing process, which improves the bonding strength between the outer layer board 10 and the inner layer board 20, and thus is beneficial to improving the service life of the cover plate; at the same time, it effectively improves the preparation efficiency and reduces the preparation cost; the collection areas 113 of the inner layer board 20 and the outer layer board 10 are formed in one step by a hot pressing process, effectively ensuring the position accuracy of the collection area 113 on the cover plate.

[0180] In the embodiment of the present disclosure, after selecting the hot pressing process to form the first blank from multiple inner layer plates 21, the first leather layer 11 and the second leather layer 12, it further includes:

[0181] Placing the first blank in the third mold 70 and selecting a cold pressing process to transform the first blank into a second blank;

[0182] Removing the release film 40;

[0183] Machining the second blank to open through holes 1131 corresponding to the collection module of the electronic device in the inner layer board 20 and the first leather layer 11.

[0184] Using a cold pressing device to perform cold pressing on the first blank. The cold pressing device includes a third mold 70, and the third mold 70 has a shape adapted to the collection area 113.

[0185] As Figure 12 shown, placing the first blank on the third mold 70 of the cold pressing device and selecting a cold pressing process to transform the first blank into a second blank. The cold pressing process makes the second blank maintain a stable shape and structure.

[0186] The process parameters of the cold pressing process include temperature, pressure, and cold pressing duration, which are set according to actual requirements. For example, the temperature can be maintained at room temperature; the pressure ranges around 100 kilograms; the cold pressing duration is 40 - 50 seconds. After hot pressing and forming, the first blank is taken out from the second mold 60, and the temperature of the first blank is usually relatively high; the first blank is placed in the third mold 70 of the cold pressing fixture for cold pressing treatment, so that the first blank can cool down quickly. After the cold pressing treatment, the first blank is transformed into a second blank with stable geometric shape and size.

[0187] After the cold pressing treatment is completed, the second blank is taken out from the third mold 70, and the release film 40 is separated from the outer layer board 10, which can be directly torn by hand, and the release film 40 is torn off from multiple leather layers.

[0188] After that, the second blank is cut and polished on a machining device according to the length and width dimensions set for corresponding models such as mobile phones, tablets, laptops, etc. It can be understood that during the machining process, the inner layer board 20 and the outer layer board 10 included in the second blank are cut simultaneously, and the excess materials on the inner layer board 20 and the outer layer board 10 are cut off along the circumferential direction of the second blank. The excess materials include the materials in the areas near the positioning holes on multiple leather layers of the outer layer board 10.

[0189] Then, a plurality of through holes 1131 are machined in the acquisition area 113, and the number of through holes 1131 is adapted to the number of cameras. Thus, a cover plate for an electronic device is prepared.
