Description
Technical Field
[0001] This application relates to the field of electronic technologies, and particularly to an electronic device. Background Art
[0002] Currently, the antenna small board in a mobile phone is generally arranged parallel to the mobile phone screen. This arrangement of the antenna small board will occupy a relatively large planar space, thereby squeezing the waterproof space of other components or parts. Figure 1 Shown is an existing layout method of an antenna small board. It can be seen that there is a recess in the mobile phone frame for accommodating the antenna small board. The recess is hollowed out from the bottom surface of the frame (the side away from the mobile phone screen). The antenna small board is arranged adjacent to the mobile phone battery. The arrangement of the antenna small board parallel to the mobile phone screen squeezes the width space of the battery and the waterproof surface on one hand, posing great challenges to the battery capacity and the overall waterproof performance of the whole machine.

The embodiments of the present application are not limited thereto.
[0047] Figure 4, Figure 5 Exemplarily, a partial structure of the electronic device provided by the present application is shown, and the electronic device is described as a mobile phone.
[0048] Referring to Figures 2 - 12 , the electronic device may include: a screen 14, a frame body 1, a substrate 4, and a rear cover (not shown in the figure). Among them, the substrate 4 serves as a load-bearing skeleton to provide connection positions (installation positions) and placement positions for the installation of various components in the electronic device. Among them, the frame body 1 mainly plays a supporting role for the whole machine. The frame body 1 can extend around the periphery of the electronic device and the screen 14. Specifically, the frame body 1 can surround the four sides of the screen 14 to help fix the screen 14.
[0049] In one embodiment, the screen 14 may be a liquid crystal display (LCD), a light emitting diode (LED), an organic light-emitting diode (OLED), etc., and the present application does not limit this.
[0050] Referring to Figures 2 - 12 , in one embodiment, a recess 2 is provided on the inner side of the frame body 1, and an antenna sub-board 3 is inclinedly arranged in the recess 2. The antenna sub-board 3 is electrically connected to the antenna radiator; the substrate 4 is provided with a receiving position 5 for placing the battery 6. The frame body 1 surrounds the edge of the substrate 4, and the antenna sub-board 3 is adjacent to the receiving position 5.
[0051] Comparing Figure 1 and Figure 2 , Figure 1 the setting of the antenna sub-board 3 in Figure 1 destroys the integrity of the waterproof surface 13 of the frame body 1, and the antenna sub-board 3 also occupies a relatively large planar space (in the direction parallel to the screen 14). Figure 2 In , the width a of the planar space occupied by the antenna sub-board 3 is at least 3.3 mm. Figure 2 In an embodiment of the present application,
[0052] the width a of the planar space occupied by the antenna sub-board 3 is only 0.9 mm. It can be understood that by inclining the antenna sub-board 3 and arranging it in the recess 2 on the inner side of the frame body 1, on the one hand, the projected width of the antenna sub-board 3 on the plane of the electronic device is reduced, providing an expansion space for the battery 6. On the other hand, the recess 2 is formed by hollowing out the inner side of the frame body 1, avoiding the reduction of the width of the waterproof surface 13 of the frame body 1 and ensuring the waterproof performance of the electronic device.It is easy to understand that the frame body 1 can be formed of a conductive material such as metal. In another implementation, the frame body 1 can also be formed of a non-metallic material. The frame body 1 can also be formed by combining a structural part formed of a metal material and a structural part formed of a non-metallic material.
[0053] Reference Figures 9 - 12 , in one embodiment, the frame body 1 includes at least one metal outer frame 7 and at least one waterproof middle frame 8. The metal outer frame 7 is located outside the waterproof middle frame 8. Antenna cut-off openings 9 are provided at both ends of the metal outer frame 7. The metal outer frame 7 is an antenna radiator, and the concave pits 2 are provided inside the waterproof middle frame 8.
[0054] It can be understood that the waterproof middle frame 8 is formed of a non-metallic material, preferably formed of plastic, and a dielectric material can also be doped therein. By combining the metal outer frame 7 and the waterproof middle frame 8 to form the frame body 1, the weight of the frame body 1 can be reduced, the plasticity of the frame body 1 can be improved, the production and processing cost of the frame body 1 can be saved, and at the same time, the anti-drop performance of the electronic device can also be improved. In addition, in addition to playing a sealing role, the waterproof middle frame 8 can also play an electrical isolation role. The metal outer frame 7 as an antenna radiator can reduce the occupation of the internal space of the electronic device by the antenna radiator.
[0055] It should be noted that when the metal outer frame 7 is used as an antenna radiator, a connecting part 10 needs to be provided on the metal outer frame 7 and the connecting part 10 is connected to a connection point (not shown in the figure) on the antenna small board 3. It can be understood that antenna cut-off openings 9 also need to be provided on the frame body 1 to make the metal frame an antenna radiator. It is easy to understand that the number and position of the connecting parts 10 on the metal outer frame 7 and the number and position of the antenna cut-off openings 9 can be designed according to actual needs. For example, when designing as an IFA antenna, two antenna cut-off openings 9 and two connecting parts 10 are required; when designing as a Monopole antenna, two antenna cut-off openings 9 and one connecting part 10 are required; and when designing as a Loop antenna, one antenna cut-off opening 9 and one connecting part 10 are required.
[0056] Reference Figures 7 - 11 , in one embodiment, two connecting parts 10 are arranged at intervals along the length direction of the inner side of the metal outer frame 7, and the connecting parts 10 are electrically connected to the antenna small board 3. By directly abutting the connecting parts 10 on the metal outer frame 7 against the connection points on the antenna small board 3, there is no need to provide a connecting wire for electrically connecting the connecting parts 10 and the connection points on the antenna small board 3, and the occupation of the limited space inside the electronic device by wiring can be avoided. It can be understood that in order to ensure good contact between the connecting parts 10 and the antenna small board 3, leaf springs can be provided at the connection point positions of the antenna small board 3, and the connecting parts 10 are electrically connected to the connection points on the antenna small board 3 through the leaf springs.
[0057] In one embodiment, the substrate 4 and the metal outer frame 7 are integrally formed by the NMT process. The nano-injection molding process is abbreviated as NMT (NanoMolding Technology), which is a method of combining metal and plastic with nanotechnology. First, the metal surface is treated by nanometerization, and then the plastic is directly injection-molded on the metal surface to obtain a plastic + metal integrated structure technology. By integrally forming the substrate 4 and the metal outer frame 7, the connection strength between the metal outer frame 7 and the substrate 4 can be improved, and the installation and fixing process of the metal outer frame 7 can be saved.
[0058] Reference Figures 7 - 11 , in one embodiment, a fixing portion 11 is provided at the edge of the substrate 4 close to the metal outer frame 7. The fixing portion 11 is located in the recess 2. The fixing portion 11 is provided with a screw hole 12, and the antenna small board 3 is screwed to the fixing portion 11. By providing the fixing portion 11 on the substrate 4 and screwing the antenna small board 3 to the fixing portion 11, the fixing stability of the antenna small board 3 can be improved, and the relative stability between the antenna small board 3 and the metal frame can be ensured. It can be understood that in other embodiments, the antenna small board 3 can be adhered in the recess 2.
[0059] In one embodiment, the connection portion between the substrate 4 and the metal outer frame 7 is a fixing portion 11. By using the connection portion between the substrate 4 and the metal outer frame 7 as a fixing portion 11, the number of fixing portions 11 separately provided on the substrate 4 can be saved, and the space occupied by separately providing the fixing portion 11 can be saved.
[0060] Reference Figure 3 , in one embodiment, the included angle b between the axis of the screw hole 12 and the normal line of the electronic device is 70 to 80 degrees. By setting the included angle b between the axis of the screw hole 12 and the normal line of the electronic device to 70 to 80 degrees, that is, setting the included angle between the antenna small board 3 and the normal line of the electronic device to 10 to 20 degrees, the setting of the recess 2 is facilitated within this angle range, and at the same time, the installation of the antenna small board 3 is convenient. Preferably, the included angle b between the axis of the screw hole 12 and the normal line of the electronic device is 75 degrees. By setting the included angle b between the axis of the screw hole 12 and the normal line of the electronic device to 75 degrees, that is, setting the included angle between the antenna small board 3 and the normal line of the electronic device to 15 degrees, better antenna radiation efficiency can be obtained at this angle.
[0061] In one embodiment, the frame body 1 is injection-molded with the waterproof middle frame 8 by using the metal outer frame 7 as an insert.
[0062] It should be noted that the above embodiments can be freely combined according to needs. The above is only the preferred embodiment of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present application.
