Description

Technical Field

[0001] The embodiments of the present application relate to a housing, a method for preparing the housing, and an electronic device, belonging to the field of electronic devices. Background Art

[0002] With the rapid development of electronic technology, electronic devices such as mobile phones and tablets have become commonplace in people's daily lives. These devices often feature logos (short for logotype, generally referring to logos or trademarks) on their housings. Logos are a crucial element in electronic devices, representing the brand and its value. However, placing logos on the housings of these devices can increase the thickness of the housings, hindering the thinness and lightweight nature of these devices. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a housing, a method for preparing the housing, and an electronic device, so as to improve the technical problem of the large thickness of the housing of the electronic device.

[0004] In order to achieve the above objectives, the present invention provides the following solutions:

[0005] In one aspect, a housing is provided, comprising a flexible skin, a glass fiber structure, and an identification structure. The flexible skin has an escape hole extending through the flexible skin in a first direction. The glass fiber structure and the flexible skin are stacked in the first direction, and the glass fiber structure and the flexible skin are in direct contact and adhesion. This arrangement allows the flexible skin and the glass fiber structure to be in direct contact and adhesion, which helps reduce the thickness of the housing and achieve a thinner and lighter housing. Furthermore, due to the high strength of the glass fiber structure, it also helps improve the strength of the housing.

[0006] The identification structure includes a base portion and a raised portion. The base portion is embedded in the fiberglass structure, and at least a portion of the raised portion extends into the avoidance hole. The orthographic projection of the raised portion on the reference surface is located within the outer contour of the orthographic projection of the base portion on the reference surface. The base portion and the flexible cover overlap along a first direction, and the reference surface is perpendicular to the first direction. This arrangement prevents the base portion from falling off, thereby preventing the identification structure from falling off and increasing the connection reliability of the identification structure.

[0007] In some implementations, the fiberglass structure includes a first portion and a second portion stacked along a first direction. The first portion is positioned between the flexible cover and the second portion. The first portion has a communication hole extending through the first portion along the first direction. The second portion has a mounting slot that connects between the avoidance hole and the mounting slot. The raised portion is positioned within the communication hole, and the base portion is positioned within the mounting slot, with the base portion being bonded to the flexible cover. This arrangement further enhances the connection reliability of the marker structure.

[0008] In some implementations, the first part includes at least one layer of a first glass fiber base cloth, and the second part includes at least one layer of a second glass fiber base cloth; the glass fiber structure also includes a molding adhesive, and the molding adhesive is filled in the gaps of the first glass fiber base cloth, in the gaps of the second glass fiber base cloth, between the first glass fiber base cloth and the second glass fiber base cloth, and between the first glass fiber base cloth and the flexible skin; the glass fiber structure is in contact with and bonded to the flexible skin, including: the glass fiber structure and the flexible skin are bonded by the molding adhesive.

[0009] In some implementations, the base portion and the flexible skin are bonded together by bonding the base portion and the flexible skin together using a molded adhesive. The base portion and the first portion may overlap along a first direction, and a portion of the molded adhesive filled in the first fiberglass base fabric may be located between the flexible skin and the base portion. This allows the base portion and the flexible skin to be bonded together using the molded adhesive, thereby further increasing the connection reliability of the sign structure.

[0010] In some implementations, the housing further includes an adhesive layer, and the first portion and the raised portion are bonded together via the adhesive layer; the base portion and the flexible cover are bonded together, including: the base portion and the flexible cover are bonded together via the adhesive layer. This arrangement allows the base portion and the flexible cover to be bonded together via the adhesive layer, further enhancing the connection reliability of the sign structure. Furthermore, the adhesive layer can prevent the molded adhesive from diffusing to the raised portion, thereby preventing the molded adhesive from overflowing through the avoidance hole in the flexible cover, thereby enhancing the aesthetics of the housing.

[0011] In some implementations, the fiberglass structure further includes an isolation adhesive, which is filled within gaps in the first fiberglass base fabric. The isolation adhesive is disposed around the raised portion and located between the molding adhesive and the raised portion. The base portion is bonded to the flexible skin, including bonding the base portion and the flexible skin via the isolation adhesive. The isolation adhesive filled within the first fiberglass base fabric can be located between the flexible skin and the base portion, allowing the two to be bonded via the isolation adhesive, further enhancing the connection reliability of the sign structure. Furthermore, the isolation adhesive can prevent the molding adhesive from diffusing to the raised portion, thereby preventing the molding adhesive from overflowing through the avoidance holes in the flexible skin, thereby enhancing the aesthetics of the housing.

[0012] In some implementations, the isolation adhesive comprises at least one of polyurethane and acrylic. This configuration ensures that the isolation adhesive has a lower strength and hardness than the molding adhesive. During the fiberglass structure fabrication process, the first and second fiberglass base fabrics filled with the molding adhesive are hot-pressed, subjecting the flexible skin and base to a certain degree of pressure. The lower strength and hardness of the isolation adhesive reduces the pressure transferred from the base to the flexible skin, thereby preventing indentations on the flexible skin.

[0013] On the other hand, a method for preparing a shell is provided. The shell includes an identification structure and a flexible shell. The method comprises: attaching the identification structure to the flexible shell, wherein the flexible shell has an avoidance hole extending through the flexible shell in a first direction; the identification structure includes a base portion and a raised portion, at least a portion of the raised portion extending into the avoidance hole, an orthographic projection of the raised portion on a reference surface being within an outer contour of an orthographic projection of the base portion on the reference surface; the base portion and the flexible shell overlapping in the first direction, the reference surface being perpendicular to the first direction; stacking a preformed structure and the flexible shell in the first direction so that the preformed structure contacts and is bonded to the flexible shell, and the base portion is embedded in the preformed structure; and performing a hot press forming process on the preformed structure to form a glass fiber structure. In the shell formed by the above arrangement, the flexible shell and the glass fiber structure are in direct contact and bonded, which helps reduce the thickness of the shell and achieve a thinner and lighter shell. Furthermore, due to the high strength of the glass fiber structure, the strength of the shell is also improved.

[0014] In some implementations, attaching the logo structure to the flexible leather includes: providing an adhesive layer on a side of the base portion facing the raised portion. The base portion is bonded to the flexible leather via the adhesive layer, wherein the adhesive layer is disposed around the raised portion, with the raised portion partially positioned within the avoidance hole. This arrangement allows the logo structure to be attached to the flexible leather, and the logo structure and the flexible leather to be bonded, thereby improving the reliability of the connection between the logo structure and the flexible leather.

[0015] In some implementations, stacking a preformed structure and a flexible skin along a first direction includes embedding an adhesive layer, a raised portion, and a base portion into the preformed structure, wherein the preformed structure includes at least one first fiberglass base fabric layer and at least one second fiberglass base fabric layer, and the fiberglass structure further includes a molding adhesive, the molding adhesive being filled in gaps between the first fiberglass base fabric, gaps between the second fiberglass base fabric, between the first fiberglass base fabric and the second fiberglass base fabric, and between the first fiberglass base fabric and the flexible skin, and the preformed structure and the flexible skin are bonded together via the molding adhesive. After stacking the preformed structure and the flexible skin along the first direction, the adhesive layer can be located within the communicating hole, and the base portion can be located within the mounting groove. Simultaneously, due to the contact between the preformed structure and the flexible skin, the molding adhesive in the preformed structure also bonds to the flexible skin, thereby bonding the preformed structure and the flexible skin together via the molding adhesive.

[0016] In another aspect, a method for manufacturing a housing is provided. The housing includes an identification structure and a flexible skin. The method comprises: stacking the flexible skin and a first preformed layer along a first direction, wherein the flexible skin has a relief hole extending through the flexible skin along the first direction, and the first preformed layer includes a communication hole extending through the first direction, the communication hole communicating with the relief hole. Mounting the identification structure on the flexible skin and the first preformed layer, wherein the identification structure includes a base portion and a raised portion, the raised portion extending into the communication hole and the relief hole, the raised portion having an orthographic projection on a reference surface located within an outer contour of an orthographic projection of the base portion on the reference surface, the base portion overlapping the flexible skin along the first direction, the reference surface being perpendicular to the first direction. Stacking a second preformed layer, the first preformed layer, and the flexible skin along the first direction, such that the first preformed layer is located between the second preformed layer and the flexible skin, and the base portion is embedded within the second preformed layer. The second preformed layer and the first preformed layer are thermoformed so that the second preformed layer and the first preformed layer together form a fiberglass structure, which is in contact with and bonded to the flexible skin. In the housing formed by the above arrangement, the flexible skin and the glass fiber structure are in direct contact and adhesion, which is conducive to reducing the thickness of the housing and achieving a lighter and thinner housing. At the same time, due to the high strength of the glass fiber structure, it is also conducive to improving the strength of the housing.

[0017] In some implementations, attaching the identification structure to the flexible skin and the first preformed layer includes: inserting a raised portion of the identification structure into the avoidance hole and the communication hole. Filling the first preformed layer with an isolation adhesive, wherein the first preformed layer includes at least one layer of a first fiberglass base fabric, and the isolation adhesive is disposed around the raised portion. Applying a first preset temperature and a first preset pressure to the first preformed layer to cure the isolation adhesive. This arrangement allows the base portion and the flexible skin to be bonded together via the isolation adhesive.

[0018] In some implementations, attaching the identification structure to the flexible skin and the first preformed layer includes: disposing a film layer on the side of the base portion facing the raised portion, the film layer containing an isolation adhesive, and surrounding the raised portion. The raised portion of the identification structure is inserted into the avoidance hole and the communication hole. A second preset temperature and a second preset pressure are applied to the film layer to diffuse the isolation adhesive within the film layer into the interior of the first preformed layer, wherein the first preformed layer includes at least one layer of a first fiberglass base fabric. This arrangement allows the base portion and the flexible skin to be bonded together via the isolation adhesive.

[0019] In some implementations, the second preformed layer includes at least one second glass fiber base fabric stacked along a first direction, and a molding adhesive filled at least within gaps within the second glass fiber base fabric. The second preformed layer, the first preformed layer, and the flexible skin are stacked along the first direction, including: diffusing the molding adhesive within the second preformed layer into the first preformed layer, with the isolation adhesive positioned between the molding adhesive and the raised portion. This arrangement allows the first and second preformed layers to be bonded together via the molding adhesive. Furthermore, because the molding adhesive diffused into the first preformed layer also contacts the flexible skin, the first preformed layer and the flexible skin can also be bonded together via the molding adhesive.

[0020] In another aspect, an electronic device is provided, comprising a battery and a middle frame, wherein the battery is mounted within the middle frame; the electronic device further comprises a housing according to any of the above embodiments; the housing is disposed on one side of the battery and is connected to the middle frame. The electronic device provided in the embodiments of the present application includes the housing as described above, and thus has all the aforementioned beneficial effects, which will not be further elaborated here.

[0035] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0036] In the following, the terms "first," "second," etc., are used for descriptive convenience only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0037] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0038] In the embodiments of the present application, directional indications such as up, down, left, right, front, and back, used to explain the structure and movement of various components of the present application are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0039] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0040] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values may, in practice, be based on additional conditions or values beyond those stated.

[0041] As used herein, "about" or "approximately" includes the stated value and the average value that is within an acceptable range of deviation from the particular value, where the acceptable range of deviation is determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0042] Here, "parallel" and "perpendicular" include the described situations and situations similar to the described situations, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximately parallelism, wherein the acceptable deviation range of approximately parallelism can be, for example, a deviation within 5%; similarly, "perpendicular" includes absolute perpendicularity and approximately perpendicularity, wherein the acceptable deviation range of approximately perpendicularity can be, for example, a deviation within 5%.

[0043] The present application provides an electronic device. The electronic device may be a mobile phone, a tablet computer, a television, a smart wearable device (e.g., a smartwatch, a smart bracelet), a virtual reality (VR) device, an augmented reality (AR) device, or other terminal products. The following description will only use a mobile phone as an example.

[0044] In some embodiments, an electronic device may include a midframe and a battery, with the battery mounted within the midframe. The midframe is also used to mount and secure other components of the electronic device, such as a camera, headphones, or a receiver. The embodiments of this application do not limit other electronic components within the midframe.

[0045] In some embodiments, the electronic device may further include a housing. The housing may be located on one side of the battery and connected to the midframe. The housing may be, for example, a rear case. When the electronic device also includes a display, the housing may be located on one side of the backlight of the display, and the battery may be located between the display and the housing. The housing may be used to protect the battery and other components within the midframe and may also serve to enhance the appearance of the electronic device.

[0046] In some embodiments, the shell can be made of a glass fiber structure. Glass fiber is a man-made fiber that has the advantages of high tensile strength, high strength, and good temperature resistance. Moreover, the shell prepared using the glass fiber structure has the characteristics of high strength and low density, which can further improve the strength of the shell and reduce the weight. In order to further improve the appearance and feel of the shell, the shell also includes a flexible skin, which can be, for example, a PU (Polyurethane) skin, and the flexible skin can be bonded to the glass fiber board through an adhesive layer. In order to further improve the feel of the shell, a fabric base cloth is usually provided on the side of the flexible skin close to the adhesive layer so that the shell can obtain a soft and resilient feel. However, since the flexible skin and the glass fiber structure are bonded together through the adhesive layer and the fabric base cloth, the thickness of the shell is increased.

[0047] For the convenience of description below, the thickness direction of the flexible skin is recorded as a first direction, and the surface perpendicular to the first direction is recorded as a reference surface. Figure 1 This is a cross-sectional view of a housing provided in an embodiment of the present application. Figure 1 As shown, the glass fiber structure 10 can be a substantially flat plate structure, and the bottom surface of the glass fiber structure 10 is perpendicular to the first direction X. The embodiment of the present application is described by taking the reference plane M as the bottom surface of the glass fiber structure 10 as an example.

[0048] Continue to refer to Figure 1 In the embodiment of the present application, the flexible skin 20 and the glass fiber structure 10 are stacked along the first direction X, and the glass fiber structure 10 is in contact with and bonded to the flexible skin 20 .

[0049] The glass fiber structure 10 may include a glass fiber base cloth and a molding adhesive A1. The "glass fiber base cloth" mentioned here and below can be woven from glass fiber yarns. For example, the glass fiber yarn can refer to a single glass fiber yarn. By twisting multiple glass fiber yarns into a glass fiber strip, and weaving the multiple glass fiber strips in sequence, a woven glass fiber base cloth can be obtained. The glass fiber base cloth woven from glass fiber yarns has gaps, and the molding adhesive A1 can be filled in the gaps of the glass fiber base cloth. During the production process of the glass fiber structure 10, the flexible skin 20 and the preformed glass fiber structure 10 can be stacked and placed together in a molding mold, and then the molding adhesive A1 can be cured. During the curing and molding process of the glass fiber structure 10, the glass fiber structure 10 is brought into contact and bonded with the flexible skin 20. That is, the glass fiber structure 10 can be bonded to the flexible skin 20 through the molding adhesive. Exemplarily, the material of the molding adhesive A1 can include resin materials such as epoxy resin, polyester resin, and acrylic resin.

[0050] Through the above arrangement, the flexible skin 20 and the glass fiber structure 10 are in direct contact and adhesion, which is beneficial to reducing the thickness of the housing 1 and achieving a lighter and thinner housing 1. At the same time, due to the high strength of the glass fiber structure 10, it is also beneficial to improve the strength of the housing 1.

[0051] Continue to refer to Figure 1 The shell 1 may further include an identification structure 30 , which may be installed in the flexible skin 20 and the glass fiber structure 10 . Figure 2 This is a structural diagram of an identification structure 30 provided in an embodiment of the present application. Figure 1 and Figure 2 As shown, the identification structure 30 may include a base portion 32 and a raised portion 31. For example, the base portion 32 and the raised portion 31 may be stacked along a first direction X. The base portion 32 may be a plate-like structure, and the raised portion 31 may be connected to one side of the base portion 32. In some embodiments, the size of the raised portion 31 along the first direction X may range from 0.08 mm to 0.35 mm, and the size of the base portion 32 along the first direction X may range from 0.05 mm to 0.5 mm, so that the base portion 32 can support the raised portion 31. Of course, the shapes and sizes of the raised portion 31 and the base portion 32 described above are merely exemplary, and the embodiments of the present application do not limit the specific shapes and sizes of the raised portion 31 and the base portion 32.

[0052] The orthographic projection of the raised portion 31 of the identification structure 30 on the reference plane M may have a certain pattern shape, which may be, for example, text, a LOGO, a trademark, etc. Figure 2 As shown, Figure 2The shape of the orthographic projection of the raised portion 31 on the reference surface M is the letter "AAA". Of course, the pattern shape can also be other shapes, as long as the pattern shape can carry certain identification information.

[0053] Continue to refer to Figure 1 The flexible skin 20 may have an escape hole 21 extending through the flexible skin 20 along the first direction X, with at least a portion of the raised portion 31 extending into the escape hole 21. For example, the raised portion 31 extends into the escape hole 21, and the surface of the raised portion 31 may be flush with the surface of the flexible skin 20. With this arrangement, the raised portion 31 of the identification structure 30 can be exposed through the escape hole 21, allowing it to be directly observed without being obstructed by the flexible skin 20. Furthermore, the base portion 32 can be embedded in the fiberglass structure 10, allowing the identification structure 30 to be installed within the fiberglass structure 10, thereby securing the identification structure 30.

[0054] Continue to refer to Figure 1 , the orthographic projection of the raised portion 31 on the reference plane M is located within the outer contour of the orthographic projection of the base portion 32 on the reference plane M, and the reference plane M is perpendicular to the first direction X. Exemplarily, in a plane parallel to the reference plane M, the cross-sectional dimension of the base portion 32 may be larger than the cross-sectional dimension of the raised portion 31. Moreover, the base portion 32 overlaps with the flexible skin 20 along the first direction X. Exemplarily, the portion of the flexible skin 20 surrounding the edge of the raised portion 31 may overlap with the base portion 32 along the first direction X. Through the above arrangement, the flexible skin 20 can prevent the base portion 32 from falling off, thereby preventing the identification structure 30 from falling off and increasing the connection reliability of the identification structure 30.

[0055] In some embodiments, part of the raised portion 31 may be located in the flexible skin 20, and part of the raised portion 31 may also be located in the fiberglass structure 10. Figure 1 As shown, the fiberglass structure 10 may include a first portion 11 and a second portion 12 stacked along a first direction X. The first portion 11 may be located between the flexible skin 20 and the second portion 12 .

[0056] Exemplarily, the first part 11 and the second part 12 can be an integrally molded structure. The glass fiber base cloth can include a first glass fiber base cloth and a second glass fiber base cloth. The first part 11 can include at least one layer of the first glass fiber base cloth, and the second part 12 can include at least one layer of the second glass fiber base cloth. Based on the above structure, the molding adhesive A1 can be filled in the gaps of the first glass fiber base cloth, in the gaps of the second glass fiber base cloth, between the first glass fiber base cloth and the second glass fiber base cloth, and between the first glass fiber base cloth and the flexible skin 20. During the manufacturing process of the glass fiber structure 10, the first glass fiber base cloth and the second glass fiber base cloth filled with the molding adhesive A1 need to be hot-pressed to enable the first part 11 and the second part 12 of the glass fiber structure 10 to be integrally molded. During the hot-pressing process, the molding adhesive A1 is cured, and the cured molding adhesive A1 helps to improve the connection strength between the first glass fiber base cloth and the flexible skin 20 of the glass fiber structure 10.

[0057] Part of the raised portion 31 may be located in the avoidance hole 21 of the flexible skin 20 , part of the raised portion 31 may be located in the first portion 11 of the glass fiber structure 10 , and the base portion 32 may be located in the second portion 12 .

[0058] Reference Figure 1 The first portion 11 may have a connecting hole 111 that passes through the first portion 11 along the first direction X. The second portion 12 may have a mounting groove 121 that connects the avoidance hole 21 and the mounting groove 121. Based on the above structure, the connecting hole 111 may be formed in at least one layer of the first fiberglass base cloth so that the first portion 11 has the connecting hole 111, and the mounting groove 121 may be formed in at least one layer of the second fiberglass base cloth so that the second portion 12 has the mounting groove 121.

[0059] Accordingly, a portion of the raised portion 31 can be located within the connecting hole 111 of the first portion 11, and the base portion 32 can be located within the mounting groove 121. The shapes of the connecting hole 111 and the avoidance hole 21 can be configured accordingly based on the shape of the raised portion 31. For example, the raised portion 31 can be substantially cylindrical, and the connecting hole 111 and the avoidance hole 21 can have the same shape. The shape of the mounting groove 121 can be configured accordingly based on the shape of the base portion 32. For example, the base portion 32 can be substantially a rectangular flat plate, and the mounting groove 121 can be substantially a rectangular groove.

[0060] Alternatively, in some embodiments, the protrusion 31 may be entirely located within the flexible skin 20. For example, the fiberglass structure 10 may include only the second portion 12, and the base portion 32 may be located within the mounting groove 121 of the second portion 12. The base portion 32 may also be located within the flexible skin 20. This arrangement further reduces the thickness of the housing 1, making the housing 1 thinner and lighter.

[0061] In this embodiment of the present application, the base portion 32 can be bonded to the flexible cover 20. For example, the communication hole 111 can be filled with glue, and the base portion 32 can be bonded to the flexible cover 20 via the glue. Alternatively, the first portion 11 can have a certain degree of adhesiveness, and the base portion 32 can be bonded to the flexible cover 20 via the first portion 11. This arrangement further enhances the connection reliability of the identification structure 30.

[0062] In some embodiments, the base portion 32 and the flexible skin 20 can be bonded together by a molded adhesive A1, thereby achieving bonding between the base portion 32 and the flexible skin 20. Figure 1 As shown, the base portion 32 and the first portion 11 can overlap along the first direction X, and part of the molded adhesive A1 filled in the first glass fiber base cloth can be located between the flexible skin 20 and the base portion 32, so that the base portion 32 and the flexible skin 20 can be bonded by the molded adhesive A1, which is beneficial to further increase the connection reliability of the identification structure 30.

[0063] Figure 3 This is a cross-sectional view of another housing 1 provided in an embodiment of the present application. Figure 3 As shown, in some embodiments, the housing 1 may further include an adhesive layer 40. The first portion 11 and the raised portion 31 are bonded together via the adhesive layer 40, and the base portion 32 and the flexible skin 20 are bonded together via the adhesive layer 40, thereby achieving adhesion between the base portion 32 and the flexible skin 20. For example, in a cross-section parallel to the reference plane M, the cross-sectional dimensions of the communication hole 111 may be larger than the cross-sectional dimensions of the avoidance hole 21, and the adhesive layer 40 may be located within the communication hole 111. For example, the adhesive layer 40 may be located between the wall of the communication hole 111 and the raised portion 31, and between the base portion 32 and the flexible skin 20. The adhesive layer 40 may also be disposed around the raised portion 31. The adhesive layer 40 may comprise an adhesive film, such as an EVA (Polyethylene Vinyl Acetate) film, a POE (Poly or Ethylene-1-octene copolymer) film, an epoxy film, an acrylic film, a polyurethane film, or the like. This arrangement allows the base portion 32 and the flexible cover 20 to be bonded together via the adhesive layer 40, further enhancing the connection reliability of the logo structure 30. Furthermore, the adhesive layer 40 prevents the molding adhesive A1 from spreading to the raised portion 31, thereby preventing the molding adhesive A1 from overflowing through the escape hole 21 of the flexible cover 20, thereby improving the aesthetics of the housing 1.

[0064] After the base portion 32 and the flexible skin 20 are bonded together by the adhesive layer 40 , a certain temperature and a certain pressure can be applied to the adhesive layer 40 to solidify the adhesive layer 40 , thereby improving the supporting effect of the adhesive layer 40 on the flexible skin 20 and improving the bonding effect of the adhesive layer 40 .

[0065] Figure 4 This is a cross-sectional view of another housing 1 provided in an embodiment of the present application. Figure 4 As shown, in some embodiments, the fiberglass structure 10 may further include an isolation adhesive A2, which is filled in the gaps of the first fiberglass base cloth. The isolation adhesive A2 is disposed around the protrusions 31 and is located between the molding adhesive A1 and the protrusions 31. The base portion 32 and the flexible skin 20 are bonded together by the isolation adhesive A2, thereby achieving bonding between the base portion 32 and the flexible skin 20.

[0066] For example, the base portion 32 and the first portion 11 may overlap along the first direction X. The first portion 11 may include a first region 11a and a second region 11b. The first region 11a is disposed around the raised portion 31, and the second region 11b is located on a side of the first region 11a away from the raised portion 31. The portion of the first fiberglass base fabric located in the first region 11a is filled with an isolation adhesive A2, while the portion of the first fiberglass base fabric located in the second region 11b is filled with a molding adhesive A1. Through this arrangement, the isolation adhesive A2 is disposed around the raised portion 31 and located between the molding adhesive A1 and the raised portion 31. The isolation adhesive A2 filled within the first fiberglass base fabric can be located between the flexible cover 20 and the base portion 32, allowing the base portion 32 and the flexible cover 20 to be bonded together via the isolation adhesive A2, further enhancing the connection reliability of the identification structure 30. Furthermore, the isolation adhesive A2 can prevent the molding adhesive A1 from diffusing to the protrusion 31 , thereby preventing the molding adhesive A1 from overflowing through the avoidance hole 21 of the flexible skin 20 , thereby facilitating improvement of the aesthetics of the housing 1 .

[0067] After the base portion 32 and the flexible skin 20 are bonded together by the isolation adhesive A2, a first preset temperature and a first preset pressure can be applied to the isolation adhesive A2 to cure the isolation adhesive A2, thereby improving the isolation adhesive A2's support for the flexible skin 20 and also improving the bonding effect of the isolation adhesive A2. Due to the relatively small area of the isolation adhesive A2, the temperature and pressure applied to the isolation adhesive A2 can be easily controlled during curing. This can prevent the isolation adhesive A2 from overflowing through the escape hole 21 of the flexible skin 20 due to excessive temperature and pressure, thereby improving the aesthetics of the housing 1.

[0068] In some embodiments, the material of the isolation adhesive A2 may include at least one of polyurethane (PU) or acrylic acid. Specifically, when the material of the isolation adhesive A2 includes polyurethane or acrylic acid, the strength and hardness of the isolation adhesive A2 are less than the strength and hardness of the molding adhesive A1. During the preparation of the glass fiber structure 10, the first glass fiber base cloth and the second glass fiber base cloth filled with the molding adhesive A1 need to be hot-pressed, and the flexible skin 20 and the base portion 32 will also be subjected to a certain pressure. The strength and hardness of the isolation adhesive A2 are relatively small, which can reduce the pressure transmitted from the base portion 32 to the flexible skin 20, thereby avoiding indentations on the flexible skin 20. Of course, in the embodiment of the present application, the material of the isolation adhesive A2 can also be selected from other adhesives with lower strength and hardness, and the embodiment of the present application does not specifically limit this.

[0069] In some embodiments, the material of the isolation adhesive A2 can also be the same as that of the molding adhesive A1. For example, the material of the isolation adhesive A2 can include epoxy resin. The above configuration is conducive to further improving the strength and hardness of the housing 1.

[0070] The embodiment of the present application further provides a method for preparing the housing 1 , which is used to prepare the housing 1 in any of the above embodiments. The housing 1 may include an identification structure 30 and a flexible skin 20 . Figure 5 This is a flowchart of a method for preparing a housing 1 according to an embodiment of the present application. Figure 5 , the preparation method of the shell 1 may include steps S101-S103.

[0071] S101. Install the identification structure on the flexible skin, wherein the flexible skin has an avoidance hole, the avoidance hole penetrates the flexible skin along a first direction, the identification structure includes a base portion and a raised portion, and at least a portion of the raised portion extends into the avoidance hole.

[0072] In the embodiment of the present application, the orthographic projection of the protrusion 31 on the reference plane M can be located within the outer contour of the orthographic projection of the base portion 32 on the reference plane M, the base portion 32 and the flexible skin 20 can overlap along the first direction X, and the reference plane M is perpendicular to the first direction X. Figure 6 This is a structural diagram of installing the identification structure 30 on the flexible skin 20 in a method for preparing a housing 1 provided in an embodiment of the present application. Figure 6 Before attaching the logo structure 30 to the flexible cover 20, an adhesive layer 40 may be disposed on the side of the base portion 32 facing the raised portion 31. For example, the adhesive layer 40 may comprise an adhesive film, such as an EVA film, a POE film, an epoxy film, an acrylic film, or a polyurethane film. The adhesive layer 40 may be attached to the side of the base portion 32 facing the raised portion 31 and may be disposed around the raised portion 31.

[0073] In the embodiment of the present application, after the adhesive layer 40 is provided on the side of the base portion 32 facing the raised portion 31, the base portion 32 can be adhered to the flexible skin 20 through the adhesive layer 40, wherein the adhesive layer 40 is provided around the raised portion 31, and part of the raised portion 31 is located in the avoidance hole 21.

[0074] Continue to refer to Figure 6 The flexible skin 20 can be processed through punching, laser engraving, CNC molding, and other processes to form the avoidance hole 21 of the flexible skin 20. The raised portion 31 can be inserted into the avoidance hole 21 of the flexible skin 20, and the base portion 32 and the flexible skin 20 can be bonded together via the adhesive layer 40. After the base portion 32 and the flexible skin 20 are bonded together via the adhesive layer 40, a certain temperature and pressure can be applied to the adhesive layer 40 to solidify the adhesive layer 40, thereby improving the support effect of the adhesive layer 40 on the flexible skin 20 and improving the bonding effect of the adhesive layer 40. Through the above arrangement, the logo structure 30 is installed on the flexible skin 20, and the logo structure 30 and the flexible skin 20 are bonded, which is conducive to improving the connection reliability between the logo structure 30 and the flexible skin 20.

[0075] Figure 7 This is another structural diagram of installing the identification structure 30 on the flexible skin 20 in a method for preparing the housing 1 provided in an embodiment of the present application. Figure 7 The flexible cover 20 may be provided with a plurality of positioning holes 23, which can be used to position the flexible cover 20, thereby improving the assembly accuracy between the identification structure 30 and the flexible cover 20. Excess portions of the flexible cover 20 may be subsequently removed by punching, laser engraving, CNC molding, or other processes to obtain the desired housing shape.

[0076] In some embodiments, positioning holes 23 are provided on the flexible cover 20, and the identification structure 30 can be moved to the flexible cover 20 to secure the flexible cover 20 and the identification structure 30 together. Alternatively, the flexible cover 20 can be mounted on the identification structure 30. For example, a positioning structure can be provided on the identification structure 30, and the movable flexible cover 20 can be moved to the identification structure 30 to secure the flexible cover 20 and the identification structure 30 together.

[0077] In the embodiment of the present application, after the identification structure 30 is installed on the flexible skin 20 , step S102 is further included.

[0078] S102 , stacking the preformed structure and the flexible skin along a first direction so that the preformed structure contacts and adheres to the flexible skin, and the base portion is embedded in the preformed structure.

[0079] In the embodiment of the present application, the preformed structure 90 may include a first preformed layer 91 and a second preformed layer 92. The first preformed layer 91 may include at least one layer of a first fiberglass base fabric, and the second preformed layer 92 may include at least one layer of a second fiberglass base fabric. The preformed structure 90 may also include a molding adhesive A1, which is filled in the gaps between the first fiberglass base fabric, the gaps between the second fiberglass base fabric, between the first fiberglass base fabric and the second fiberglass base fabric, and between the first fiberglass base fabric and the flexible skin 20. The molding adhesive A1 in the preformed structure 90 may be an adhesive that has not been fully cured, and the preformed structure 90 is also a prepreg.

[0080] Figure 8 This is a structural diagram of a method for preparing a shell 1 provided in an embodiment of the present application, wherein a preformed structure 90 and a flexible skin 20 are stacked. Figure 8 During the stacking of the preformed structure 90 and the flexible skin 20 , the adhesive layer 40 , the raised portion 31 , and the base portion 32 may be embedded in the preformed structure 90 , and the preformed structure 90 and the flexible skin 20 may be bonded together by the molding adhesive A1 .

[0081] For example, the preformed structure 90 can be processed by punching, laser engraving, CNC molding, or other processes to form the accommodation space 13 of the preformed structure 90. In some embodiments, the accommodation space 13 can include a connecting hole 111 and a mounting groove 121. The connecting hole 111 and the mounting groove 121 have the same cross-sectional shape on the reference plane M, and the connecting hole 111 and the mounting groove 121 can be formed simultaneously. The connecting hole 111 can be provided along the first direction X through at least one layer of the first fiberglass base fabric of the first preformed layer 91, and the mounting groove 121 can be provided in at least one layer of the second fiberglass base fabric of the second preformed layer 92. After the preformed structure 90 and the flexible skin 20 are stacked along the first direction X, the adhesive layer 40 can be located within the connecting hole 111, and the base portion 32 can be located within the mounting groove 121. At the same time, since the preformed structure 90 is in contact with the flexible skin 20 , the molding adhesive A1 in the preformed structure 90 is also bonded to the flexible skin 20 , so that the preformed structure 90 and the flexible skin 20 are bonded together through the molding adhesive A1 .

[0082] In the embodiment of the present application, after the preformed structure 90 and the flexible skin 20 are stacked along the first direction X, step S103 is further included.

[0083] S103, performing a hot pressing process on the preformed structure to form the preformed structure into a glass fiber structure.

[0084] In the embodiment of this application, Figure 3As shown, during the hot press forming process of the preformed structure 90, the flexible skin 20 and the preformed fiberglass structure 10 can be placed together in a forming mold, and a preset temperature and pressure are applied to the preformed structure 90 to cure the molding adhesive A1 in the preformed structure 90. Through this arrangement, the first fiberglass base fabric of the first preformed layer 91, the second fiberglass base fabric of the second preformed layer 92, and the molding adhesive A1 form an integrated structure, which is the fiberglass structure 10. Furthermore, since the bonding effect of the molding adhesive A1 improves during the curing process, the connection reliability between the flexible skin 20 and the fiberglass structure 10 is further improved.

[0085] At the same time, during the hot pressing process, the adhesive layer 40 can prevent the molding adhesive A1 from diffusing to the protrusion 31 , thereby preventing the molding adhesive A1 from overflowing through the avoidance hole 21 of the flexible skin 20 , which is beneficial to improving the aesthetics of the shell 1 .

[0086] In summary, the direct contact and bonding between the flexible skin 20 and the glass fiber structure 10 is beneficial to reducing the thickness of the housing 1 and achieving a thinner and lighter housing 1. At the same time, the high strength of the glass fiber structure 10 is also beneficial to improving the strength of the housing 1.

[0087] The embodiment of the present application further provides a method for preparing the housing 1 , which is used to prepare the housing 1 in any of the above embodiments. The housing 1 may include an identification structure 30 and a flexible skin 20 . Figure 9 This is a flowchart of another method for preparing a housing 1 according to an embodiment of the present application. Figure 9 Combined with Figure 4 , the preparation method of the shell 1 may include steps S201-S204.

[0088] S201, stacking a flexible skin and a first preformed layer along a first direction, wherein the flexible skin has an avoidance hole, the avoidance hole penetrates the flexible skin along the first direction X, and the first preformed layer includes a connecting hole penetrated along the first direction, the connecting hole is connected to the avoidance hole.

[0089] Figure 10 This is a structural diagram of stacking the flexible skin and the first preformed layer in another method for preparing the shell 1 provided in an embodiment of the present application. Figure 10 As shown, the first preformed layer 91 may include at least one layer of first fiberglass fabric. After the flexible skin 20 and the first preformed layer 91 are stacked, they can be processed simultaneously using processes such as punching, laser engraving, and CNC molding to form the avoidance holes 21 in the flexible skin 20 and the connecting holes 111 in the first preformed layer 91. Because the avoidance holes 21 and the connecting holes 111 can be produced using the same process, the structures and shapes of the avoidance holes 21 and the connecting holes 111 can be identical.

[0090] In the embodiment of the present application, after the flexible skin 20 and the first preformed layer 91 are stacked along the first direction X, step S202 is further included.

[0091] S202: Installing a marking structure on the flexible skin and the first preformed layer, wherein the marking structure includes a base portion and a raised portion, and the raised portion extends into the communicating hole and the avoidance hole.

[0092] In the embodiment of the present application, the orthographic projection of the protrusion 31 on the reference plane M can be located within the outer contour of the orthographic projection of the base portion 32 on the reference plane M, the base portion 32 and the flexible skin 20 can overlap along the first direction X, and the reference plane M is perpendicular to the first direction X.

[0093] In the embodiment of this application, Figure 10 As shown, the raised portion 31 of the identification structure 30 can be inserted into the avoidance hole 21 and the communication hole 111. With this arrangement, the base portion 32 of the identification structure 30 is located on the side of the first preformed layer 91 away from the flexible skin 20. The first preformed layer 91 and the flexible skin 20 both overlap with the base portion 32 in the first direction X, which helps prevent the identification structure 30 from falling off the flexible skin 20 or the first preformed layer 91.

[0094] Figure 11 This is a structural diagram of filling the isolation adhesive A2 in the first preformed layer 91 in another method for preparing the housing 1 provided in an embodiment of the present application. Figure 11 As shown, in the embodiment of the present application, after the raised portion 31 of the identification structure 30 is inserted into the avoidance hole 21 and the connecting hole 111, the isolation adhesive A2 can be filled into the first preformed layer 91, wherein the first preformed layer 91 includes at least one layer of first fiberglass base cloth, and the isolation adhesive A2 is disposed around the raised portion 31. Exemplarily, the isolation adhesive A2 is filled into the first preformed layer 91, that is, the isolation adhesive A2 is filled into the gaps of the first fiberglass base cloth of the first preformed layer 91. The isolation adhesive A2 can be located between the base portion 32 and the flexible skin 20, so that the base portion 32 and the flexible skin 20 can be bonded together by the isolation adhesive A2.

[0095] In some embodiments, the process of filling the first preformed layer 91 with the release adhesive A2 may include the following steps: the volume of the release adhesive A2 required may be calculated based on the area occupied by the base portion 32, and the release adhesive A2 may be filled at the edge where the first preformed layer 91 and the base portion 32 contact (e.g., Figure 11 A corresponding volume of isolation adhesive A2 is injected (at point P in the figure) so that the isolation adhesive A2 diffuses between the base portion 32 and the flexible skin 20.

[0096] In the embodiment of the present application, after the first preformed layer 91 is filled with the release adhesive A2, a first preset temperature and a first preset pressure can be applied to the first preformed layer 91 to cure the release adhesive A2. The first preset temperature and the first preset pressure can be set to different values depending on the material of the release adhesive A2. The embodiment of the present application does not limit the specific material, the first preset temperature, and the first preset pressure of the release adhesive A2. This configuration improves the support provided by the adhesive layer 40 to the flexible leather 20 and enhances the bonding effect of the adhesive layer 40.

[0097] Figure 12 This is a structural diagram of stacking the flexible skin and the first preformed layer in another method for preparing the shell 1 provided in an embodiment of the present application. Figure 12 As shown, a film layer 80 may be provided on the side of the base portion 32 facing the protrusion 31 . The film layer 80 contains an isolation adhesive A2 , and the film layer 80 is provided around the protrusion 31 .

[0098] In the embodiment of the present application, after the adhesive film layer 80 is disposed on the side of the base portion 32 facing the raised portion 31, the raised portion 31 of the logo structure 30 can be inserted into the avoidance hole 21 and the communication hole 111. With this arrangement, the base portion 32 of the logo structure 30 is located on the side of the first preformed layer 91 away from the flexible leather 20, and the base portion 32 and the first preformed layer 91 are bonded together by the adhesive film layer 80.

[0099] Figure 13 This is a structural diagram of applying temperature and pressure to the film layer 80 in another method for preparing the housing 1 provided in an embodiment of the present application. Figure 13 As shown, in the embodiment of the present application, after the raised portion 31 of the identification structure 30 is inserted into the avoidance hole 21 and the connecting hole 111, a second preset temperature and a second preset pressure can be applied to the film layer 80 to allow the isolation adhesive A2 in the film layer 80 to diffuse into the interior of the first preformed layer 91, wherein the first preformed layer 91 includes at least one layer of first glass fiber base cloth. Depending on the material of the isolation adhesive A2, different second preset temperatures and second preset pressures can be set accordingly. The embodiment of the present application does not limit the specific material, second preset temperature, and second preset pressure of the isolation adhesive A2. The above-mentioned settings allow the isolation adhesive A2 to solidify, which is beneficial to improving the support effect of the isolation adhesive A2 on the flexible skin 20 and also improves the bonding effect of the isolation adhesive A2.

[0100] As described in the above embodiment, positioning structures can be provided on the flexible skin 20 and the first preformed layer 91, and the identification structure 30 can be moved to the flexible skin 20 and the first preformed layer 91 to secure the flexible skin 20, the first preformed layer 91, and the identification structure 30 together. Alternatively, the flexible skin 20 and the first preformed layer 91 can be attached to the identification structure 30. For example, positioning structures can be provided on the identification structure 30, and the flexible skin 20 and the first preformed layer 91 can be moved to the identification structure 30 to secure the flexible skin 20, the first preformed layer 91, and the identification structure 30 together.

[0101] In the embodiment of the present application, after the identification structure 30 is installed on the flexible skin 20 and the first preformed layer 91 , step S203 is further included.

[0102] S203 , stacking the second preform layer, the first preform layer, and the flexible skin along a first direction, so that the first preform layer is located between the second preform layer and the flexible skin, and the base portion is embedded in the second preform layer.

[0103] Figure 14 This is a structural diagram of another method for preparing the housing 1 provided in an embodiment of the present application, wherein the second preformed layer 92, the first preformed layer 91 and the flexible skin 20 are stacked. Figure 14 As shown, in the embodiment of the present application, the second preformed layer 92 may include at least one second glass fiber base fabric stacked along the first direction X, and a molding adhesive A1 at least filling the gaps between the second glass fiber base fabrics. The molding adhesive A1 in the second preformed layer 92 may be an adhesive that has not been fully cured, and the second preformed layer 92 is also a prepreg.

[0104] The second preformed layer 92 can be processed by punching, laser engraving, CNC forming or other processes to form the mounting groove 121 of the second preformed layer 92 , and the base portion 32 can be embedded in the mounting groove 121 of the second preformed layer 92 .

[0105] When the second preformed layer 92, the first preformed layer 91, and the flexible skin 20 are stacked along the first direction X, the second preformed layer 92 contacts the first preformed layer 91. The molding adhesive A1 in the second preformed layer 92 diffuses into the first preformed layer 91, and the isolation adhesive A2 is located between the molding adhesive A1 and the protrusions 31. This arrangement allows the first preformed layer 91 and the second preformed layer 92 to be bonded together via the molding adhesive A1. Simultaneously, because the molding adhesive A1 diffused into the first preformed layer 91 also contacts the flexible skin 20, the first preformed layer 91 and the flexible skin 20 can also be bonded together via the molding adhesive A1.

[0106] In the embodiment of the present application, after the second preformed layer 92 , the first preformed layer 91 and the flexible skin 20 are stacked along the first direction X, step S204 is further included.

[0107] S204 , performing a hot pressing process on the second preformed layer and the first preformed layer, so that the second preformed layer and the first preformed layer together form a glass fiber structure, and the glass fiber structure contacts and is bonded to the flexible skin.

[0108] In the embodiment of the present application, during the thermoforming process of the second preformed layer 92 and the first preformed layer 91, a predetermined temperature and pressure can be applied to the second preformed layer 92 and the first preformed layer 91 to cure the molding adhesive A1 in the thermoformed structure. This arrangement allows the first fiberglass base fabric, the second fiberglass base fabric, and the molding adhesive A1 to form an integrated structure, which is the fiberglass structure 10. Furthermore, since the bonding effect of the molding adhesive A1 improves during the curing process, the connection reliability between the flexible skin 20 and the fiberglass structure 10 is further improved.

[0109] At the same time, during the hot pressing process, the isolation adhesive A2 can block the molding adhesive A1 from diffusing to the protrusion 31 , thereby preventing the molding adhesive A1 from overflowing through the avoidance hole 21 of the flexible skin 20 , which is beneficial to improving the aesthetics of the shell 1 .

[0110] In summary, the direct contact and bonding between the flexible skin 20 and the glass fiber structure 10 is beneficial to reducing the thickness of the housing 1 and achieving a thinner and lighter housing 1. At the same time, the high strength of the glass fiber structure 10 is also beneficial to improving the strength of the housing 1.

[0111] In some embodiments, the isolation adhesive A2 can be omitted, or the film layer can be omitted. When the second preformed layer 92, the first preformed layer 91 and the flexible skin 20 are stacked, the molding adhesive A1 diffuses into the first glass fiber base cloth and further diffuses between the base portion 32 and the flexible skin 20, so that the base portion 32 and the flexible skin 20 can be bonded by the molding adhesive A1.

[0112] In some embodiments, before stacking the second preformed layer 92, the first preformed layer 91, and the flexible skin 20 in the first direction, an adhesive film may be disposed on the surface of the second preformed layer 92. The adhesive film may be disposed around the mounting groove 121 and may include a release adhesive A2. When the second preformed layer 92, the first preformed layer 91, and the flexible skin 20 are stacked in the first direction X, the adhesive film is positioned between the first preformed layer 91 and the second preformed layer 92. Applying a certain temperature and pressure to the adhesive film allows the release adhesive A2 within the adhesive film to diffuse into the first preformed layer 91, at which point the first preformed layer 91 is completely filled with the release adhesive A2. The second preformed layer 92 is then subjected to a heat press molding process to cure the molding adhesive A1, bonding the first preformed layer 91 to the second preformed layer 92.

[0113] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in this application should be included within the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
