[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] To address the issue of low antenna communication performance in electronic devices in related technologies, this application provides an electronic device that improves the communication performance of the FPC antenna by placing the FPC antenna on the outer side, inner side, and frame end face of the front housing, thereby reducing the obstruction of the FPC antenna by internal components.

[0066] The principles and features of the embodiments of this application are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of this application and are not intended to limit the scope of the embodiments of this application.

[0067] It should be noted that, in the description of the embodiments of this application, "front side" refers to the side of the electronic device facing the user when it is in normal use. "Rear side" refers to the side opposite to the front side, that is, the side of the electronic device facing away from the user when it is in normal use.

[0068] refer to Figure 1 and Figure 2 This application provides an electronic device, including a housing 10, a display screen 20, and an FPC antenna 30. The display screen 20 is disposed on the front side of the housing 10.

[0069] refer to Figure 1 and Figure 2 The housing 10 includes a front housing 110 and a rear cover 140 connected to each other. The rear cover 140 is located behind the front housing 110, and the rear cover 140 and the front housing 110 enclose a mounting space for mounting other components of the electronic device.

[0070] refer to Figure 3 The front cover 110 includes a side frame 120 and a connecting plate 130, with the connecting plate 130 connected to the side of the side frame 120 away from the rear cover 140.

[0071] The display screen 20 is located on the side of the connecting plate 130 away from the back cover 140, that is, the display screen 20 is located on the front side of the connecting plate 130.

[0072] refer to Figure 3 The side frame 120 has an outer facade 121, an inner facade 123, and a frame end face 122.

[0073] The frame end face 122 is located on the side of the side frame 120 that faces away from the display screen 20 along the thickness direction. The thickness direction of the side frame 120 is also the thickness direction of the electronic device.

[0074] The outer facade 121 is the exposed vertical surface of the side frame 120, which is perpendicular to the plane where the display screen 20 is located. The inner facade 123 is opposite to the outer facade 121, and the inner facade 123 is approximately perpendicular to the plane where the display screen 20 is located. The inner facade 123 faces the installation space.

[0075] The outer facade 121, the frame end face 122, and the inner facade 123 are connected in sequence. The outer facade 121 and the frame end face 122 are partially opposite to the rear cover 140.

[0076] There may be one or more FPC antennas 30. The FPC antenna 30 may be at least one of the following: cellular communication antenna, GPS (Global Positioning System) positioning antenna, Bluetooth antenna, and WiFi (Wireless Fidelity) antenna.

[0077] refer to Figure 4 The FPC antenna 30 includes a first bonding portion 310, a second bonding portion 320, and a third bonding portion 330 connected to each other. (Reference) Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The first fitting part 310 is fitted to the outer facade 121. The second fitting part 320 is fitted to the frame end face 122. The third fitting part 330 is fitted to the inner facade 123.

[0078] Since both the outer facade 121 and the frame end face 122 are opposite to the rear cover 140, the first fitting portion 310 attached to the outer facade 121 and the second fitting portion 320 attached to the frame end face 122 are also opposite to the rear cover 140, making them less likely to be blocked by components within the installation space, thus improving the communication performance of the FPC antenna 30. The third fitting portion 330 attached to the inner facade 123 is located at the outer edge of the installation space, and therefore is also less likely to be blocked by components within the installation space, further improving the communication performance of the FPC antenna 30.

[0079] The electronic device provided in this application embodiment reduces the obstruction of the FPC antenna 30 by the components inside the housing 10 by disposing the FPC antenna 30 on the outer side 121, inner side 123 and frame end face 122 of the front housing 110, thereby improving the communication performance of the FPC antenna 30.

[0080] In some possible implementations of the embodiments of this application, reference is made to Figure 3 and Figure 6The outer facade 121 is provided with a first recess 1211 that is recessed toward the inner facade 123. At least a portion of the first fitting portion 310 is disposed in the first recess 1211 to reduce the height of the first fitting portion 310 protruding from the outer facade 121 in the direction away from the inner facade 123. This reduces the size of the side frame 120 and the first fitting portion 310 as a whole in the direction parallel to the display screen 20, thereby reducing the size of the electronic device in the direction parallel to the display screen 20.

[0081] refer to Figure 3 and Figure 6 The frame end face 122 is provided with a second recess 1221 that is recessed toward the display screen 20. At least a portion of the second fitting portion 320 is disposed in the second recess 1221 to reduce the height of the second fitting portion 320 protruding from the frame end face 122 in the direction away from the display screen 20. This reduces the size of the side frame 120 and the second fitting portion 320 as a whole in the direction perpendicular to the display screen 20, thereby reducing the size of the electronic device in the direction perpendicular to the display screen 20.

[0082] refer to Figure 10 and Figure 11 The inner facade 123 is constructed with a third recess 1231 that is recessed toward the outer facade 121. At least a portion of the third fitting portion 330 is disposed in the third recess 1231 to reduce the height of the third fitting portion 330 protruding from the inner facade 123 in the direction away from the outer facade 121, thereby reducing the installation space occupied by the third fitting portion 330.

[0083] In some possible implementations of this application, the side of the first fitting portion 310 facing away from the inner facade 123 is flush with the outer facade 121. This can reduce the height of the first fitting portion 310 protruding from the outer facade 121 in the direction facing away from the inner facade 123, thereby reducing the size of the electronic device in the direction perpendicular to the display screen 20; and can also avoid the first recess 1211 being too deep, which would reduce the structural strength of the side frame 120.

[0084] The second bonding portion 320 is flush with the frame end face 122 on the side away from the display screen 20. This can reduce the height of the second bonding portion 320 protruding from the frame end face 122 in the direction away from the display screen 20, thereby reducing the size of the electronic device in the direction perpendicular to the display screen 20. It can also avoid the second recess 1221 being too deep, which would reduce the structural strength of the side frame 120.

[0085] The third fitting part 330 is flush with the inner side facade 123 on the side opposite to the outer facade 121. This way, the third fitting part 330 does not occupy installation space, and the depth of the third recess 1231 is not too large, which would reduce the structural strength of the side frame 120.

[0086] In some possible implementations of the embodiments of this application, reference is made to Figure 3 A positioning post 1212 is provided within the first recess 1211, and the axis of the positioning post 1212 can be perpendicular to the outer facade 121. (Reference) Figure 4 and Figure 6 The first bonding part 310 is provided with a positioning hole 311, and the positioning post 1212 is inserted into the positioning hole 311 to position the first bonding part 310 and the outer facade 121, thereby reducing the positioning difficulty of the first bonding part 310 when it is attached to the outer facade 121.

[0087] There can be multiple positioning posts 1212, which are arranged at intervals. Correspondingly, the first fitting part 310 can be constructed with multiple positioning holes 311, and the positioning holes 311 are set one-to-one with the positioning posts 1212. Each positioning post 1212 is inserted into the corresponding positioning hole 311 to improve the positioning accuracy of the first fitting part 310 and the outer facade 121.

[0088] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 11 A limiting rib 1222 is provided at one end of the frame end face 122 that is away from the outer facade 121, and the limiting rib 1222 extends circumferentially along the side frame 120.

[0089] refer to Figure 6 and Figure 11 The second bonding part 320 is constructed with a limiting hole 321, and the limiting rib 1222 is inserted into the limiting hole 321 to position the second bonding part 320 and the frame end face 122, thereby reducing the difficulty of positioning the second bonding part 320 on the frame end face 122.

[0090] refer to Figure 6 Along the direction perpendicular to the inner facade 123, the size of the limiting hole 321 is larger than the size of the limiting rib 1222 to accommodate the assembly tolerance between the second fitting part 320 and the frame end face 122 and to compensate for machining errors. Furthermore, the larger size of the limiting hole 321 allows the limiting rib 1222 to be quickly aligned and easily inserted into the limiting hole 321, reducing the difficulty of mounting the second fitting part 320 to the frame end face 122.

[0091] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 9 The frame end face 122 may include a straight portion 1223 and a chamfered portion 1224.

[0092] The straight section 1223 is parallel to the plane where the display screen 20 is located.

[0093] Along a direction perpendicular to the outer facade 121, the periphery of the straight portion 1223 is spaced from the outer facade 121. The periphery of the straight portion 1223 is the edge of the straight portion 1223 that faces away from the installation space.

[0094] The chamfered portion 1224 is connected to the periphery of the straight portion 1223 and the end of the outer facade 121 that is away from the display screen 20. The distance between the chamfered portion 1224 and the plane where the display screen 20 is located increases from the end closer to the outer facade 121 to the end farther away from the outer facade 121.

[0095] refer to Figure 6 and Figure 9 The second fitting part 320 is fitted with the straight part 1223, and the other part is fitted with the chamfered part 1224.

[0096] By providing a chamfered portion 1224 between the outer facade 121 and the straight portion 1223, the sharpness of the connection between the outer facade 121 and the chamfered portion 1224, as well as the sharpness of the connection between the chamfered portion 1224 and the straight portion 1223, is reduced, thereby reducing wear on the FPC antenna 30 caused by the side frame 120. Furthermore, the degree of bending of the second bonding portion 320 relative to the first bonding portion 310 is reduced, decreasing the possibility of damage to the FPC antenna 30 due to excessive bending.

[0097] In some possible implementations of the embodiments of this application, reference is made to Figure 4 and Figure 6 The second fitting portion 320 is constructed with a plurality of stress holes 322 arranged circumferentially along the side frame 120. The stress holes 322 are opposite to the chamfered portion 1224. The stress holes 322 can reduce the possibility of the second fitting portion 320 warping and at the same time improve the flexibility of the second fitting portion 320, making it easier for the second fitting portion 320 to fit with the frame end face 122.

[0098] In some possible implementations of the embodiments of this application, reference is made to Figure 3 The outer facade 121 may be provided with snap-fit ​​protrusions 1225.

[0099] refer to Figure 4 and Figure 6 The first fitting part 310 may be configured with a relief opening 312 for the snap-fit ​​protrusion 1225 to pass through.

[0100] refer to Figure 12 The rear cover 140 includes a first cover portion 141, a second cover portion 142, and a third cover portion 143. (See reference) Figure 13 and Figure 14 The second cover portion 142 is opposite to the frame end face 122. The third cover portion 143 is opposite to the connecting plate 130.

[0101] The first cover portion 141 is opposite to the outer facade 121. A mating protrusion 1411 is provided on the side of the first cover portion 141 facing the outer facade 121. The mating protrusion 1411 is engaged with the side of the engaging protrusion 1225 facing the display screen 20 to engage the rear cover 140 with the front shell 110, so as to facilitate the assembly of the front shell 110 and the rear cover 140.

[0102] In some possible implementations of the embodiments of this application, reference is made to Figure 14 The snap-fit ​​protrusion 1225 has a first guide surface 1226 on the side opposite to the display screen 20. The distance between the first guide surface 1226 and the plane where the display screen 20 is located decreases from the end away from the first cover portion 141 to the end closer to the first cover portion 141.

[0103] The protrusion 1411 has a second guide surface 1412 on the side near the display screen 20. The distance between the second guide surface 1412 and the plane where the display screen 20 is located decreases from the end away from the outer facade 121 to the end near the outer facade 121. The second guide surface 1412 and the first guide surface 1226 are opposite each other in a direction perpendicular to the plane where the display screen 20 is located.

[0104] When assembling the rear cover 140 with the front shell 110, the rear cover 140 is placed behind the front shell 110, and then the rear cover 140 is moved from back to front. When the second guide surface 1412 contacts the first guide surface 1226, the front shell 110 and the rear cover 140 are pressed together. The protrusion 1411 moves along the first guide surface 1226 to the side of the snap-fit ​​protrusion 1225 facing the display screen 20, and engages with the stop of the snap-fit ​​protrusion 1225 facing the display screen 20, thereby realizing the installation of the rear cover 140 and the front shell 110.

[0105] In some possible implementations of the embodiments of this application, reference is made to Figure 2 The electronic device may also include a motherboard 40, which is located inside the side frame 120, that is, assembled in the installation space, and is located on the side of the connecting plate 130 opposite to the display screen 20.

[0106] The FPC antenna 30 is electrically connected to the motherboard 40 to achieve bidirectional transmission of radio frequency signals, while ensuring the normal resonance and signal transmission and reception performance of the FPC antenna 30.

[0107] In some possible implementations of the embodiments of this application, the electronic device may further include a bracket 50, a lens 60, and a battery 70. The bracket 50 and the battery 70 are disposed within the mounting space.

[0108] The lens 60 is mounted on the bracket 50, and the bracket 50 is mounted on the side of the connecting plate 130 away from the display screen 20.

[0109] The bracket 50 can cover the side of the motherboard 40 away from the display screen 20 to fix and protect the motherboard 40.

[0110] Within the battery 70 assembly and installation space, the battery 70 is electrically connected to the motherboard 40 to supply power to the motherboard 40.

[0111] The back cover 140 covers the outside of the battery 70 and the bracket 50 to shield the battery 70 and the bracket 50, thereby improving the decorative effect of the electronic device.

[0112] In some possible implementations of the embodiments of this application, the electronic device provided in the embodiments of this application can be implemented in various forms. For example, the electronic device described in this application may include mobile terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.
