[0024] In the related art, the middle frame and the screen are often fixed by a combination of glue dispensing, back glue and glue injection. Among them, since the glue injection hole is set on the back of the middle frame, when the repair involves disassembling and installing the screen, the battery cover needs to be disassembled and glue is re-injected, and then the battery cover is reinstalled, which leads to high repair and disassembly costs.

[0025] In order to solve the above technical problems, according to an embodiment of the present disclosure, a shell assembly and an electronic device are provided, the shell assembly comprising: a middle frame; a rear shell, the rear shell being arranged on a first surface of the middle frame; a through hole, the through hole passing through at least a portion of the middle frame and the rear shell, the first end of the through hole being arranged on the rear shell, and the second end of the through hole being arranged on a second surface of the middle frame opposite to the first surface; and a decorative component, the decorative component covering the first end of the through hole.

[0026] The present invention provides a through hole that penetrates the middle frame and the rear shell for glue injection. When the middle frame and functional parts are reinstalled, there is no need to separate the rear shell and the middle frame, which reduces the maintenance steps and saves the cost of disassembling and assembling the rear shell. The through hole is covered by the decorative part, thereby improving the aesthetics of the electronic device.

[0029] Figure 1 is an exploded view of a housing assembly according to an exemplary embodiment. Figure 2 is a partial top view of a housing assembly according to an exemplary embodiment. Figure 3 is a cross-sectional view of a housing assembly according to an exemplary embodiment. Figure 4 The figure is a schematic diagram showing a structure of a middle frame with functional parts removed according to an exemplary embodiment.

[0030] In some embodiments, Figure 1-Figure 4 As shown, the housing assembly may include: a middle frame 1 , a rear shell 2 , a through hole 3 and a decorative member 4 , and the rear shell 2 may be disposed on a first surface of the middle frame 1 .

[0031] The middle frame 1 may be a frame structure that provides support and fixing functions. The middle frame 1 may be a metal middle frame, a plastic middle frame, a glass middle frame, a ceramic middle frame, etc., but the present disclosure does not specifically limit the type of the middle frame 1, that is, those skilled in the art may adjust its type according to actual conditions, as long as it is a frame structure that can be used to provide support and fixing functions.

[0032] The rear shell 2 may be a shell structure with covering and protection functions. The shell may be a metal shell, a plastic shell, a glass shell, a ceramic shell, etc., but the present disclosure does not specifically limit the type of the rear shell 2, that is, those skilled in the art may adjust its type according to actual conditions, as long as it is a shell structure that can be used to provide covering and protection functions.

[0033] The rear shell 2 may be a rear cover of an electronic device, and is a plate-like structure that protects and supports the internal components of the device. For example, in an electronic device such as a mobile phone or a tablet computer, the rear shell 2 may be a cover that protects and fixes the battery, and the rear shell 2 may be arranged opposite to the middle frame 1.

[0034] The through hole 3 may penetrate at least a portion of the middle frame 1 and the rear cover 2 .

[0035] The first end 31 of the through hole 3 may be disposed on the rear housing 2 , and the second end 32 of the through hole 3 may be disposed on the second surface of the middle frame 1 opposite to the first surface.

[0036] During disassembly and repair, glue can be injected from the first end 31 of the through hole 3 , and the glue can flow into the second surface of the middle frame 1 through the through hole 3 , thereby completing the glue injection operation without disassembling the rear shell 2 .

[0037] The decorative member 4 may cover the first end 31 of the through hole 3 , thereby concealing the through hole 3 in appearance and keeping the housing assembly beautiful.

[0038] The present invention provides a through hole 3 that passes through the middle frame 1 and the rear shell 2 for glue injection. When the middle frame 1 and the functional component 5 are reinstalled, there is no need to separate the rear shell 2 from the middle frame 1, thereby reducing the maintenance steps and saving the cost of disassembling and assembling the rear shell 2. The through hole 3 is covered by the decorative component 4, thereby improving the aesthetics of the electronic device.

[0039] In some embodiments, Figure 1-Figure 4 As shown, the housing assembly may include: a functional component 5 and a first adhesive component 6 .

[0040] The functional component 5 may be disposed on the second surface of the middle frame 1 , and the functional component 5 may be a component of the electronic device disposed on the second surface of the middle frame 1 with any function.

[0041] The first adhesive 6 can be arranged on the functional component 5 and the second surface of the middle frame 1. The first adhesive 6 can provide a certain bonding effect between the functional component 5 and the second surface of the middle frame 1, thereby improving the fixation between the functional component 5 and the middle frame 1, and the first adhesive 6 can seal at least a portion of the gap between the functional component 5 and the second surface of the middle frame 1, thereby improving the sealing between the functional component 5 and the second surface of the middle frame 1.

[0042] The first adhesive member 6 can be disposed between the functional member 5 and the middle frame 1 through the through hole 3. For example, during disassembly and repair, the first adhesive member 6 can be poured into the through hole 3 of the rear housing 2 through the first end 31, and flow to the second surface of the middle frame 1 through the through hole 3, thereby completing the glue pouring operation without disassembling the rear housing 2.

[0043] The present invention provides a through hole 3 that passes through the middle frame 1 and the rear shell 2 and injects the first adhesive 6. When the middle frame 1 and the functional component 5 are reinstalled, the first adhesive 6 can be re-set through the through hole 3 without separating the rear shell 2 and the middle frame 1, thereby reducing the maintenance steps and saving the cost of disassembling and assembling the rear shell 2. The through hole 3 is covered by the decorative component 4, thereby improving the aesthetics of the electronic device.

[0044] In some embodiments, Figure 1-Figure 4 As shown, the housing assembly may include: a second adhesive component 7 and a third adhesive component 8 .

[0045] The second adhesive member 7 and the third adhesive member 8 may be disposed between the second surface of the middle frame 1 and the functional component 5 , and bond the second surface of the middle frame 1 and the functional component 5 .

[0046] Among them, the first adhesive 6 can be arranged between the second adhesive 7 and the third adhesive 8, and at least a part of the first adhesive 6 can be bonded to the second adhesive 7, and at least another part of the first adhesive 6 can be bonded to the third adhesive 8, so that the first adhesive 6 seals the gap between the second adhesive 7 and the third adhesive 8, so that the first adhesive 6, the second adhesive 7 and the third adhesive 8 can completely seal the functional part 5 and the second surface of the middle frame 1 together, preventing liquid and water vapor from entering the interior of the electronic device from the gap between the functional part 5 and the middle frame 1 bracket, thereby improving the waterproof performance of the electronic device and meeting the waterproof design requirements of the electronic device.

[0047] The second adhesive 7 and the third adhesive 8 can be directly disposed on the surface of the functional component 5 or the second surface of the middle frame 1 when the functional component 5 is removed, and can adhere the functional component 5 and the second surface of the middle frame 1 when the functional component 5 is installed.

[0048] For example, in a possible case, the second adhesive member 7 can be a preformed double-sided tape, one side of which is pasted on the side of the middle frame 1 opposite to the functional member 5, and the other side is pasted on the side of the functional member 5 opposite to the middle frame 1, so as to connect the two. This method is easy to operate and has a reliable bonding effect.

[0049] However, the present disclosure is not limited to this. In another possible case, the second adhesive component 7 can also be an adhesive layer formed by coating an acrylic adhesive on the surface of the middle frame 1 opposite to the functional component 5. The adhesive layer can completely or partially cover the side of the middle frame 1 opposite to the functional component 5 to achieve a firm bond between the two.

[0050] In another possible case, the second adhesive member 7 can also be made of silicone, and a silicone point of a certain shape is formed on the surface of the middle frame 1 opposite to the functional member 5 by injection or screen printing, and is bonded to the side of the functional member 5 opposite to the middle frame 1 to play a connecting and fixing role. In this way, the raw materials are easily available, the process is simple, and the production cost can be reduced.

[0051] For example, in a possible case, the third adhesive member 8 can be a preformed double-sided tape, one side of which is pasted on the side of the middle frame 1 opposite to the functional member 5, and the other side is pasted on the side of the functional member 5 opposite to the middle frame 1, so as to connect the two. This method is easy to operate and has a reliable bonding effect.

[0052] However, the present disclosure is not limited to this. In another possible case, the third adhesive component 8 can also be an adhesive layer formed by coating an acrylic adhesive on the surface of the middle frame 1 opposite to the functional component 5. The adhesive layer can completely or partially cover the side of the middle frame 1 opposite to the functional component 5 to achieve a firm bond between the two.

[0053] In another possible case, the third adhesive member 8 can also be made of silicone, and a silicone point of a certain shape is formed on the surface of the middle frame 1 opposite to the functional member 5 by injection or screen printing, and is bonded to the side of the functional member 5 opposite to the middle frame 1 to play a connecting and fixing role. In this way, the raw materials are easily available, the process is simple, and the production cost can be reduced.

[0054] It should be noted that the second adhesive 7 and the third adhesive 8 may be arranged on the side opposite to the functional part 5 of the middle frame 1, and the opposite side may be a substantially parallel surface in direct contact with the functional part 5 of the middle frame 1, and the first adhesive 6 is arranged between the two substantially parallel surfaces to realize the bonding structure of the connection and bonding between the middle frame 1 and the functional part 5. Among them, the first adhesive 6 may include at least one of double-sided adhesive, hot melt adhesive, silicone adhesive, amino adhesive, acrylic adhesive, epoxy resin, and polyurethane adhesive, but the present disclosure does not specifically limit the type of the first adhesive 6, that is, those skilled in the art may set or adjust according to actual conditions, as long as the second adhesive 7 and the third adhesive 8 can realize the connection between the side opposite to the middle frame 1 and the functional part 5.

[0055] The first adhesive 6 can be poured into the through hole 3 of the rear shell 2 through the first end 31 and flow between the second adhesive 7 and the third adhesive 8 through the through hole 3, thereby completing the glue filling operation without disassembling the rear shell 2 and achieving the sealing of the functional component 5 and the middle frame 1.

[0056] For example, the first adhesive 6 may include a single-component dam silicone, which may be dispensed between the second adhesive 7 and the third adhesive 8 to achieve connection and bonding between the two and form a reliable sealing structure. In addition, the single-component dam silicone has good fluidity and viscosity, is easy to operate, and has excellent sealing performance.

[0057] It is understandable that the present disclosure does not specifically limit the specific forms of the first adhesive 6, the second adhesive 7 and the third adhesive 8. The above situation is only an exemplary description of the forms in which the first adhesive 6, the second adhesive 7 and the third adhesive 8 can exist, but is not limited to the situation described in the above embodiment. As long as the first adhesive 6, the second adhesive 7 and the third adhesive 8 have adhesive properties, adhesive sealing can be achieved. In other words, as long as it is under this condition, those skilled in the art can adjust the specific form of any one or combination of the first adhesive 6, the second adhesive 7 and the third adhesive 8 according to actual conditions.

[0058] In some embodiments, the decorative piece 4 can be bonded or snap-connected to the rear shell 2 to achieve a detachable connection between the decorative piece 4 and the rear shell 2, so that the decorative piece 4 can be removed during maintenance to expose the through hole 3, and the decorative piece 4 can be installed back into the rear shell 2 when the maintenance is completed, thereby reducing the difficulty of operation during maintenance.

[0059] The present disclosure is not limited thereto, and the decorative member 4 and the shell may also be installed and connected in other detachable ways, and during maintenance, the decorative member 4 may be disassembled from the shell, or the disassembled decorative member 4 may be installed on the shell.

[0060] In some embodiments, Figure 1 As shown, the rear shell 2 is provided with a receiving portion 21 , the first end 31 of the through hole 3 can be disposed at the bottom of the receiving portion 21 , and the decorative element 4 can be disposed in the receiving portion 21 .

[0061] The decorative element 4 includes an outer surface, the rear housing 2 includes a shell surface, and the outer surface is flush with the shell surface.

[0062] Exemplarily, the accommodating portion 21 can be a portion on the rear shell 2 that is recessed toward the middle frame 1, and the decorative member 4 can be arranged in the accommodating portion 21, so that the decorative member 4 does not protrude from the rear shell 2, making the overall appearance of the rear shell 2 smooth and flat, thereby improving the overall aesthetics of the shell assembly and also improving the grip feel of the rear shell 2.

[0063] It should be noted that the receiving portion 21 may be a rectangular groove structure, or the receiving portion 21 may be a circular pit structure. The number and size of the recessed portions may be adjusted or set by a person skilled in the art according to actual conditions, and the depth of the receiving portion 21 may also be designed according to the height of the decorative element 4.
