Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and in particular to an electronic device. Background Technology

[0002] Currently, mobile phones, tablets, and other electronic devices are widely used in people's daily lives. The screen assembly of a mobile phone is located on one side of the mid-frame, and the edge of the screen assembly is sealed to the mid-frame. Because the edge area of ​​the screen assembly needs to accommodate connecting lines and flexible circuit boards, the area where the screen assembly overlaps with the mid-frame is relatively small, making it difficult to guarantee the sealing performance at the connection point. Utility Model Content

[0003] Therefore, embodiments of this disclosure provide an electronic device that can improve the installation sealing performance of screen components.

[0004] The electronic device provided in this disclosure includes a bracket and a screen assembly, wherein the screen assembly covers one side of the bracket;

[0005] The screen assembly includes a cover plate and a display panel. The display panel is connected to the side of the cover plate near the bracket. The bracket is provided with an annular stepped surface. The edge area of ​​the cover plate is in contact with the stepped surface. The stepped surface is provided with a groove. The groove is filled with an adhesive. The stepped surface is bonded to the cover plate through the adhesive.

[0006] In some embodiments of this disclosure, the depth direction of the groove is inclined relative to the thickness direction of the cover plate. This inclination of the groove relative to the thickness direction of the cover plate prevents excessive thinning of the bracket in its thickness or width direction, ensuring sufficient thickness at the edge of the bracket. This improves the strength of the bracket and thus enhances the overall durability of the electronic device.

[0007] In some embodiments of this disclosure, the angle between the depth direction of the groove and the thickness direction of the cover plate is 30° to 60°. Maintaining an appropriate angle between the depth direction of the groove and the thickness direction of the cover plate can better accommodate the tilt angle of the cutting tool, facilitating the cutting of the bracket.

[0008] In some embodiments of this disclosure, the electronic device further includes a mid-frame, a camera assembly, and a battery cover. The battery cover is connected to one side of the mid-frame, and a bracket is connected to the side of the battery cover away from the mid-frame. The battery cover has a cutout area, the bracket covers the cutout area, and the screen assembly has a first through-hole. One end of the camera assembly passes through the cutout area and the first through-hole sequentially and is fixedly connected to the screen assembly. The first through-hole and the cutout area can avoid obstructing the camera assembly, preventing the screen assembly from interfering with the camera assembly's shooting function.

[0009] In some embodiments of this disclosure, the screen assembly further includes a first circuit board located on the side of the display panel near the mid-frame and electrically connected to the display panel, the cover plate having opposing first and second edges, the first through hole located on the side of the cover plate near the first edge, and the first circuit board located on the side of the cover plate near the second edge.

[0010] In some embodiments of this disclosure, the electronic device further includes a second circuit board and a motherboard, the second circuit board being electrically connected to both the motherboard and the first circuit board. The second circuit board's electrical connection to both the first circuit board and the motherboard eliminates the need for a direct connection between the first circuit board and the motherboard, allowing for a smaller first circuit board and preventing damage during assembly.

[0011] In some embodiments of this disclosure, the electronic device further includes a focus sensor, a distance sensor, and a flash. The focus sensor, the distance sensor, and the flash are located on one side of the second circuit board and are electrically connected to the second circuit board. The flash is used as a flash or flashlight during shooting. The focus sensor helps the camera assembly to focus quickly and accurately, improving the user's photography experience. The distance sensor is used to detect the distance between external objects and the electronic device, enabling automatic screen-off during calls and preventing accidental touches of the electronic device in a pocket.

[0012] In some embodiments of this disclosure, the bracket is provided with a second through hole, which is stacked on top of the first through hole. The stacked second through hole and the first through hole are used to accommodate the end of the camera assembly protruding from the screen assembly.

[0013] In some embodiments of this disclosure, the camera assembly includes a protective plate and a decorative element surrounding the edge of the protective plate. The decorative element and the protective plate are located on the side of the screen assembly away from the mid-frame. The protective plate covers the first through-hole and is sealingly connected to the screen assembly via the decorative element. The protective plate and decorative element serve to close the first through-hole, thereby protecting the lens and other components mounted within the mid-frame.

[0014] In some embodiments of this disclosure, the decorative element includes a decorative ring and a sealing plate. The decorative ring surrounds and is connected to the sealing plate, which is located between the protective plate and the screen assembly. The sealing plate is made of plastic, and the decorative ring is made of metal. The decorative ring and the sealing plate form an insulating barrier to prevent external static electricity from being transmitted into the camera assembly and damaging sensors or other components within the camera assembly.

[0015] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0016] In the electronic device provided in the embodiments of this disclosure, the cover plate of the screen assembly is attached to the stepped surface of the bracket. A groove is provided on the stepped surface, and the groove is filled with adhesive. The groove can increase the contact area between the stepped surface and the cover plate, and can accommodate a larger volume of adhesive, so that the adhesive can be tightly bonded to the stepped surface and the cover plate, thereby improving the sealing performance of the connection between the screen assembly and the bracket.

Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0033] This disclosure provides an electronic device that can expand the display function of the electronic device.

[0034] Figure 1 An exploded view of an electronic device provided in an embodiment of this disclosure; Figure 2 A partial cross-sectional view of an electronic device provided in an embodiment of this disclosure. (See attached image.) Figure 1-2 As shown, the electronic device provided in this embodiment includes a bracket 5 and a screen assembly 2, with the screen assembly 2 covering one side of the bracket 5. The screen assembly 2 includes a cover plate 204 and a display panel 205. The display panel 205 is connected to the side of the cover plate 204 near the bracket 5. The bracket 5 is provided with an annular stepped surface 502. The edge area of ​​the cover plate 204 is in contact with the stepped surface 502. The stepped surface 502 is provided with a groove 503, which is filled with an adhesive 504. The stepped surface 502 is bonded to the cover plate 204 through the adhesive 504.

[0035] In the electronic device provided in the embodiments of this disclosure, the cover plate 204 of the screen assembly 2 is attached to the stepped surface 502 of the bracket 5. A groove 503 is provided on the stepped surface 502, and the groove 503 is filled with colloid 504. The groove 503 can increase the contact area between the stepped surface 502 and the cover plate 204, and can accommodate a larger volume of colloid 504, so that the colloid 504 can be tightly bonded to the stepped surface 502 and the cover plate 204, thereby improving the sealing performance at the connection between the screen assembly 2 and the bracket 5.

[0036] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0037] See Figure 1-2 The electronic device includes a bracket 5 and a screen assembly 2. The screen assembly 2 covers one side of the bracket 5 and is fixedly connected to the bracket 5. The screen assembly 2 includes a cover plate 204 and a display panel 205. The display panel 205 is connected to the side of the cover plate 204 near the bracket 5. The bracket 5 has an annular stepped surface 502. The edge area of ​​the cover plate 204 fits against the stepped surface 502 and is fixedly connected to it. The stepped surface 502 has a groove 503 filled with an adhesive 504. The stepped surface 502 is bonded to the cover plate 204 through the adhesive 504. The groove 503 increases the area of ​​the stepped surface 502, allowing the stepped surface 502 to fully contact the cover plate 204 and sealing the connection through the adhesive 504, thereby improving the sealing performance of the connection between the screen assembly 2 and the bracket 5 and enhancing the waterproof performance of the electronic device.

[0038] In some embodiments of this disclosure, see Figure 2 The depth direction of the groove 503 is inclined relative to the thickness direction of the cover plate 204. This inclination of the groove 503 relative to the thickness direction of the cover plate 204 prevents excessive thinning of the bracket 5 in its thickness or width direction, ensuring sufficient thickness in the edge area of ​​the bracket 5. This improves the strength of the bracket 5 and thus enhances the overall durability of the electronic device. Furthermore, by setting the axis of the CNC machine tool to be perpendicular to the depth direction of the groove 503, cutting of the groove 503 can be performed, avoiding interference from the step surface 502 on the cutting tool. This reduces the machining difficulty of the bracket 5 and helps lower its production cost.

[0039] Optionally, the angle between the depth direction of the groove 503 and the thickness direction of the cover plate 204 is 30° to 60°. For example, the angle between the depth direction of the groove 503 and the thickness direction of the cover plate 204 is 45 degrees. Maintaining an appropriate angle between the depth direction of the groove 503 and the thickness direction of the cover plate 204 can better adapt to the angle of the cutting tool, facilitating the cutting of the bracket 5.

[0040] In some embodiments of this disclosure, such as Figure 1 As shown, the electronic device also includes a mid-frame 1, a camera assembly 3, and a battery cover 4. The battery cover 4 is connected to one side of the mid-frame 1, and a bracket 5 is connected to the side of the battery cover 4 away from the mid-frame 1. The battery cover 4 has a hollow area 401, which is covered by the bracket 5. The screen assembly 2 has a first through-hole 201. One end of the camera assembly 3 passes through the hollow area 401 and the first through-hole 201 and is fixedly connected to the screen assembly 2. Due to the relatively large thickness of the camera assembly 3, the first through-hole 201 and the hollow area 401 can avoid interfering with the camera assembly 3's shooting function. The screen assembly 2 is used to realize functions such as message display, rear camera shooting preview, and wallpaper display, expanding the display function of the electronic device and improving the user experience.

[0041] Figure 3 A schematic diagram of a screen assembly of an electronic device provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 2-3 As shown, the screen assembly 2 also includes a first circuit board 206. The first circuit board 206 is located on the side of the display panel 205 near the middle frame 1 and is electrically connected to the display panel 205. The cover plate 204 has opposing first edges 202 and second edges 203. A first through hole 201 is located on the side of the cover plate 204 near the first edge 202, and the first circuit board 206 is located on the side of the cover plate 204 near the second edge 203. The first circuit board 206 is used to electrically connect the screen assembly 2 to external circuits. The first through hole 201 and the first circuit board 206 are located on opposite sides of the cover plate 204, which makes the camera assembly 3 and the first circuit board 206 separated by a large distance, thereby avoiding the first circuit board 206 from affecting the arrangement and shooting of the camera assembly 3, and optimizing the mounting structure of the screen assembly 2 on the battery cover 4.

[0042] In some embodiments of this disclosure, such as Figure 1 As shown, the electronic device also includes a second circuit board 7 and a main board 6. The second circuit board 7 is electrically connected to both the main board 6 and the first circuit board 206. Because the second circuit board 7 is electrically connected to both the first circuit board 206 and the main board 6, it eliminates the need for a direct connection between the first circuit board 206 and the main board 6. This allows for a smaller first circuit board 206, preventing damage during assembly.

[0043] Optionally, see Figure 1The bracket 5 has a second through hole 505, which is stacked on top of a first through hole 201. The stacked second through hole 505 and first through hole 201 are used to accommodate the end of the camera assembly 3 protruding from the screen assembly 2. For example, the bracket 5 has two second through holes 505, and the screen assembly 2 has two first through holes 201, with each second through hole 505 overlapping a first through hole 201. The two second through holes 505 and two first through holes 201 are used to accommodate two camera assemblies 3, thus meeting the requirement of setting multiple camera assemblies 3 in electronic devices.

[0044] In some embodiments of this disclosure, such as Figure 3 As shown, the electronic device also includes a wide-angle camera 8. The battery cover 4 has a mounting hole 402, and the wide-angle camera 8 is located within the mounting hole 402 and electrically connected to the second circuit board 7. The focal length of the wide-angle camera 8 is smaller than that of the camera assembly 3, enabling the electronic device to adapt to more shooting scenarios, such as shooting grand scenes and large group photos.

[0045] Figure 4 This is a partial schematic diagram of an electronic device provided according to an embodiment of the present disclosure. In some embodiments of the present disclosure, such as... Figure 4 As shown, the electronic device also includes a wide-angle camera 8. The battery cover 4 has a mounting hole 402, and the wide-angle camera 8 is located within the mounting hole 402 and electrically connected to the second circuit board 7. The focal length of the wide-angle camera 8 is smaller than that of the camera assembly 3, enabling the electronic device to adapt to more shooting scenarios, such as shooting grand scenes and large group photos.

[0046] Figure 5 A schematic diagram of a second circuit board 7 of an electronic device provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 8 As shown, the electronic device also includes a focus sensor 9, a distance sensor 10, and a flash 11. The focus sensor 9, distance sensor 10, and flash 11 are located on one side of the second circuit board 7 and are electrically connected to the second circuit board 7. The flash 11 can be used as a flash or flashlight during shooting. The focus sensor 9 helps the camera assembly 3 to focus quickly and accurately, improving the user's photography experience. The distance sensor 10 detects the distance between external objects and the electronic device, enabling functions such as automatically turning off the screen during calls and preventing accidental touches of the electronic device in a pocket.

[0047] In some embodiments of this disclosure, such as Figure 3 and 5As shown, a first interface 207 is provided on the first circuit board 206, and a second interface 702 is provided on one end of the second circuit board 7. The first interface 207 and the second interface 702 are detachably electrically connected. In this embodiment, both the first interface 207 and the second interface 702 are BTB (Board-to-Board) interfaces.

[0048] Figure 6 This is a partial schematic diagram of a battery cover for an electronic device provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 5 and 6 As shown, the second circuit board 7 is provided with multiple positioning holes 701, and the bracket 5 is provided with multiple positioning posts 501 on the side near the middle frame 1. The positioning posts 501 are inserted into the positioning holes 701. The positioning posts 501 cooperate with the positioning holes 701 to fix the second circuit board 7 at a preset position on the bracket 5, preventing the second circuit board 7 from moving relative to the bracket 5.

[0049] Figure 7 This is a schematic diagram illustrating the assembly process of an electronic device provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 5-6 As shown, the second circuit board 7 is a flexible circuit board, and at least a portion of the second circuit board 7 has an S-shaped structure. The S-shaped second circuit board 7 can be bent according to connection requirements, making it easier to arrange inside the middle frame 1 and reducing the installation difficulty of the second circuit board 7.

[0050] Figure 8 A partial cross-sectional view of an electronic device provided for an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 8 As shown, the camera assembly 3 includes a protective plate 301 and a decorative element 302. The decorative element 302 surrounds the edge of the protective plate 301. The decorative element 302 and the protective plate 301 are located on the side of the screen assembly 2 away from the mid-frame 1. The protective plate 301 covers the first through-hole 201 and is sealed to the screen assembly 2 via the decorative element 302. The protective plate 301 and the decorative element 302 are used to close the first through-hole 201, thereby protecting the lens and other components installed within the mid-frame 1.

[0051] In some embodiments of this disclosure, such as Figure 8 As shown, the decorative component 302 includes a decorative ring 3021 and a sealing plate 3022. The decorative ring 3021 surrounds and is connected to the sealing plate 3022. The sealing plate 3022 is located between the protective plate 301 and the screen assembly 2. The sealing plate 3022 is made of plastic, while the decorative ring 3021 is made of metal. The decorative ring 3021 and the sealing plate 3022 form an insulating barrier to prevent external static electricity from being transmitted to the inside of the camera assembly 3 and causing damage to sensors and other devices in the camera assembly 3.

[0052] It should be noted that adhesive is applied between the sealing plate 3022 and the cover plate 204 to seal the sealing plate 3022 and the cover plate 204, thereby preventing external moisture and dust from entering the camera assembly 3.
