Technical Field

[0001] The present application belongs to the field of electronic technology, and specifically relates to an electronic device. Background Art

[0002] In the related art, the battery cover and the camera decoration are fixed together mainly by means of adhesive backing and dispensing.

[0003] Among them, when using adhesive backing to fix, the bonding force between the battery cover and the camera decoration is relatively small, and the battery cover and the camera decoration are easily separated when the pulling force or impact force is large. When using glue point fixing, the material cost of glue is high, the glue point process cost is also high, and a certain proportion of glue point failure is prone to occur, and the corresponding inspection process is complicated. Summary of the invention

[0017] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0018] In the description of the present application, it should be understood that the terms "first" and "second" may explicitly or implicitly include one or more of the features.

[0019] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0020] With the continuous development of smart phones, the appearance of mobile phones on the market has also changed accordingly. The most significant change in appearance is that the decorative circle of the rear camera of the mobile phone has gradually increased, showing a trend of horizontal expansion, which has brought great challenges to mobile phone stacking and engineering assembly.

[0021] At present, the main assembly methods of smartphone rear camera bezel and battery cover are internal and external. The internal solution is mainly to fix the battery cover with double-sided tape on the skirt, but the existence of the skirt will become a bottleneck restricting the lateral expansion of the rear camera bezel. The external solution developed on this basis cancels the skirt and directly sticks it on the surface of the battery cover with double-sided tape. In order to make up for the lack of adhesive force, screws and glue are required to prevent the rear camera bezel from falling off.

[0022] The interior solution has the following defects: since there are many devices distributed around the decorative ring, the existence of the skirt restricts the width of devices such as the antenna, reduces their performance and experience, and limits the horizontal space of the entire machine; space needs to be reserved in the thickness direction of the machine to accommodate the thickness of the skirt, resulting in a waste of space.

[0023] The external installation solution has the following defects: the external installation solution requires locking screws and glue spotting for fastening, the assembly process is complicated and the cost is high; the need to add screw holes and glue spotting grooves increases the complexity of the decorative ring structure. Compared with the internal installation solution, the processing difficulty and cost of a single decorative ring are significantly increased; it is difficult to remove glue during maintenance, which increases the maintenance cost and reduces the maintenance efficiency.

[0024] In order to solve the above problems, Figure 1 , Figure 2 and Figure 3 As shown, the electronic device according to the embodiment of the present application includes: a housing 1 , a decorative ring 2 and a mainboard assembly 3 .

[0025] Among them, the mainboard component 3 can be a mainboard, a mainboard cover or a mainboard bracket. The specific type of the mainboard component 3 is not specifically limited here and can be selected according to actual working conditions.

[0026] The mainboard assembly 3 is arranged in the housing 1, the housing 1 has an opening 10 and the decorative ring 2 is covered at the opening 10, the decorative ring 2 has a receiving groove 6, the mainboard assembly 3 is provided with a lens assembly 13, and the lens assembly 13 passes through the opening 10 and partially extends into the receiving groove 6, the peripheral side of the lens assembly 13 is movably provided with a buckle 4, and the side wall of the receiving groove 6 is provided with a buckle 8 adapted to the buckle. Among them, the lens assembly 13 includes a lens.

[0027] Among them, the buckle 4 has a first state and a second state relative to the slot 8. When the buckle 4 is in the first state, the buckle 4 is engaged with the slot 8, and the decorative ring 2 is connected to the shell 1. When the buckle 4 is in the second state, the buckle 4 is disengaged from the slot 8, and the decorative ring 2 is separated from the shell 1.

[0028] That is to say, the opening 10 is connected to the accommodating groove 6, the lens assembly 13 is passed through the opening 10, and is at least partially accommodated in the accommodating groove 6, a gap is left between the peripheral side of the lens assembly 13 and the peripheral wall of the opening 10, the projection area of ​​the mainboard assembly 3 on the shell 1 is larger than the area of ​​the opening 10, the mainboard assembly 3 can cover the opening 10, and the mainboard assembly 3 is in contact with the shell 1.

[0029] In the embodiment of the present application, when the buckle 4 is in the first state, at least part of the buckle 4 is located in the slot 8, and the buckle 4 provides a force for the decorative ring 2 toward the housing 1, so that the decorative ring 2 is sealed and connected with the housing 1. When the buckle 4 is in the second state, the buckle 4 is separated from the slot 8, and the decorative ring 2 is separated from the housing 1. Compared with the internal installation method, the decorative ring has no skirt, which helps to increase the available space inside the whole machine, especially to reduce the restrictions on the layout of devices such as antennas; compared with the external installation method, there is no need for glue dispensing and screw fastening, which simplifies the assembly process and saves costs, and there is no need to remove glue during maintenance, which reduces the difficulty of maintenance; there is no need to increase the glue dispensing groove and screw hole, and under the same convex height, the thickness of the decorative ring 2 is low, the overall processing allowance is small, and the required processing time is short, which has certain cost advantages.

[0030] In an optional embodiment, the buckle 4 is telescopically disposed on the peripheral side of the lens assembly 13 , and a first guide surface 11 is provided on a side of the bottom wall of the buckle 4 facing the accommodating groove 6 .

[0031] When the decorative ring 2 moves toward the direction close to the housing 1 , the decorative ring 2 pushes the buckle 4 to move toward the peripheral side of the lens assembly 13 by abutting against the first guide surface 11 .

[0032] It should be noted that, when the decorative ring 2 moves toward the direction close to the shell 1, the decorative ring 2 pushes the buckle 4 to move toward the peripheral side of the lens assembly 13 by abutting against the first guide surface 11. At this time, the buckle 4 is in the second state. When the decorative ring 2 abuts against the shell 1, the buckle 4 moves toward the peripheral side away from the lens assembly 13. The buckle 4 switches from the second state to the first state. At this time, at least part of the buckle 4 is located in the slot 8.

[0033] In the embodiment of the present application, the buckle 4 is retractably arranged on the peripheral side of the lens assembly 13, which can quickly realize the switching of the buckle 4 between the first state and the second state, and can improve the assembly efficiency of the decorative ring 2.

[0034] In an optional embodiment, the electronic device further includes an elastic member 5 , and the buckle 4 is connected to the peripheral side of the lens assembly 13 via the elastic member 5 .

[0035] That is to say, one end of the elastic member 5 is connected to the buckle 4 , and the other end of the elastic member 5 is connected to the peripheral side of the lens assembly 13 , and the extension direction of the elastic member 5 is perpendicular to the extension direction of the lens assembly 13 .

[0036] For example, when the decorative ring 2 moves toward the direction close to the shell 1, the decorative ring 2 pushes the buckle 4 to move toward the peripheral side of the lens assembly 13 by abutting against the first guide surface 11. At this time, the buckle 4 is in the second state and the elastic member 5 is in a compressed state. When the decorative ring 2 abuts against the shell 1, under the action of the driving force provided by the elastic member 5, the buckle 4 moves toward the peripheral side away from the lens assembly 13. The buckle 4 moves from the second state to the first state, and the elastic member 5 switches from the compressed state to the original length state. At this time, at least part of the buckle 4 is located in the slot 8.

[0037] It should be noted that the elastic member 5 can be a component with expansion and contraction capability such as a spring, which is not specifically limited here.

[0038] In the embodiment of the present application, the buckle 4 is arranged on the peripheral side of the lens assembly 13 through an elastic member, which can quickly realize the switching of the buckle 4 between the first state and the second state, thereby improving the assembly efficiency of the decorative ring 2.

[0039] In an optional embodiment, if Figure 1 and Figure 2 As shown, the buckle 4 includes an abutment portion 41 and a connecting portion 42, the connecting portion 42 is connected to the peripheral side of the lens assembly 13 through an elastic member 5, the connecting portion 42 is provided with an abutment portion 41 on the side of the bottom wall of the accommodating groove 6, and the abutment portion 41 is provided with a first guide surface 11 on the side of the bottom wall of the accommodating groove 6.

[0040] The connecting portion 42 may be a columnar body, and the abutting portion 41 may be a wedge-shaped block. The connecting portion 42 and the abutting portion 41 may be an integrated structure.

[0041] It should be noted that the position of the elastic member 5 on the peripheral side of the lens assembly 13 corresponds to the inside of the opening 10 .

[0042] In the embodiment of the present application, a fulcrum is formed at the connection between the connecting portion 42 and the elastic member 5. When the abutting portion 41 is located outside the card slot 8, the extension direction of the elastic member 5 is perpendicular to the extension direction of the connecting portion 42. When at least part of the abutting portion 41 is located in the card slot 8, the abutting portion 41 has a tendency to move toward the shell 1. The abutting portion 41 can provide a certain extrusion force for the decorative ring 2, thereby ensuring the sealed connection between the shell 1 and the decorative ring 2.

[0043] In an optional embodiment, if Figure 3 As shown, a second guide surface 7 is provided at the edge of the slot 8 , and when the decorative ring 2 moves toward the housing 1 , the second guide surface 7 abuts against the first guide surface 11 to push the buckle 4 toward the peripheral side of the lens assembly 13 .

[0044] It should be noted that the first guide surface 11 and the second guide surface 7 may be a plane.

[0045] In the embodiment of the present application, the abutment between the second guide surface 7 and the first guide surface 11 can improve the smoothness of the movement of the buckle 4 toward the peripheral side close to the lens assembly 13 .

[0046] In an optional embodiment, the angle between the second guide surface 7 and the plane where the bottom wall of the receiving groove 6 is located is α, and α is greater than 0° and less than 90°.

[0047] It should be noted that the angle α between the second guide surface 7 and the plane where the bottom wall of the receiving groove 6 is located can be 30° or 60°.

[0048] In the embodiment of the present application, when the angle α between the second guide surface 7 and the plane where the bottom wall of the accommodating groove 6 is located is not equal to the angle β between the first guide surface 11 and the plane where the mainboard assembly 3 is located, the contact area between the second guide surface 7 and the first guide surface 11 can be reduced, thereby reducing the friction force and facilitating the quick assembly of the buckle 4 in the slot 8.

[0049] In an optional embodiment, in order to ensure the sealing and connection stability between the decoration ring 2 and the housing 1 , the decoration ring 2 and the housing 1 are bonded by a glue 9 .

[0050] The colloid 9 may be a double-sided tape.

[0051] In an embodiment of the present application, before assembling the decorative ring 2 and the shell 1, a colloid 9 is provided on the edge of the shell 1 near the opening 10. When the decorative ring 2 is in contact with the shell 1, the edge of the decorative ring 2 near the accommodating groove 6 is connected to the edge of the shell 1 near the opening 10 through the colloid 9.

[0052] In addition, if Figure 1 and Figure 2 As shown, the electronic device further includes a magnetic component 12 .

[0053] The magnetic member 12 is disposed on the buckle 4 , and when the magnetic member 12 and the magnetic attraction member are in magnetic contact, the buckle 4 can be switched from a first state to a second state relative to the slot 8 .

[0054] It should be noted that the magnetic member 12 can be embedded in the buckle 4 .

[0055] It is particularly important to point out that the magnetic member 12 may be a permanent magnet. When the polarity of the magnetic attraction member is the same as that of the magnetic member 12 , the effect of like poles repelling each other is achieved.

[0056] For example, when the polarity of the magnetic element is the same as that of the magnetic element 12 , the magnetic element moves toward the peripheral side of the lens assembly 13 , and the buckle 4 can also move toward the peripheral side of the lens assembly 13 .

[0057] In the embodiment of the present application, when the decorative ring 2 is disassembled and repaired, the colloid 9 between the decorative ring 2 and the shell 1 is first removed with a blade. According to the principle of like poles repelling each other, the magnetic attraction part is moved toward the peripheral side of the lens assembly 13 on the outer side near the buckle 4, thereby driving the magnetic part 12 to move the buckle 4 toward the peripheral side of the lens assembly 13. The buckle 4 is separated from the slot 8, and the decorative ring 2 can automatically fall off from the shell 1, which is convenient for inspection and maintenance.

[0058] In an optional embodiment, the buckle 4 and the magnetic member 12 are an integrated structure.

[0059] It should be noted that the buckle 4 and the magnetic member 12 are an integrated structure, which can ensure the miniaturization of the overall structure.

[0060] In an optional embodiment, there are multiple buckles 4 , and the multiple buckles 4 are arranged in sequence along the circumferential direction of the lens assembly 13 .

[0061] For example, multiple buckles 4 are arranged in equal intervals along the circumferential direction of the lens assembly 13, and the side wall of the accommodating groove 6 is provided with an annular buckle groove 8. That is, when the multiple buckles 4 are in the first state, the multiple buckles 4 extend into the annular buckle groove 8.

[0062] In the embodiment of the present application, by providing a plurality of buckles 4 , when the plurality of buckles 4 are all in the first state, the stability of the connection between the decorative ring 2 and the housing 1 can be improved.

[0063] In an optional embodiment, there are multiple buckles 4 and multiple slots 8, and the multiple buckles 4 are arranged in sequence along the circumferential direction of the lens assembly 13, and the multiple buckles 4 and the multiple slots 8 correspond one to one.

[0064] The plurality of buckles 4 are arranged in sequence at equal intervals along the circumferential direction of the lens assembly 13 , and at the same time, the plurality of slots 8 are arranged in sequence at equal intervals along the circumferential direction of the inner wall of the accommodating groove 6 .

[0065] That is to say, when the plurality of buckles 4 are in the first state, each buckle 4 extends into the corresponding buckle slot 8 , thereby improving the stability of the connection between the decorative ring 2 and the housing 1 .
