[0022] As Figures 1 to 8 shown, an embodiment of the present application provides an electronic device, including a shielding cover 10, a circuit board 20, and a functional element 30. The functional element 30 is disposed on the circuit board 20, and the shielding cover 10 covers the functional element 30.
[0023] Among them, the functional element 30 includes a body structure 31 and a metal reinforcement plate 32 disposed on the body structure 31, and the metal reinforcement plate 32 is located between the top 11 of the shielding cover 10 and the body structure 31. There is a gap 40 between the top 11 of the shielding cover 10 and the metal reinforcement plate 32.
[0024] The electronic device further includes a first conducting member 50. At least a part of the first conducting member 50 is located in the gap 40, and the top 11 of the shielding cover 10 is electrically connected to the metal reinforcement plate 32 through the first conducting member 50.
[0025] The above-mentioned functional element 30 can be a board-to-board connector, or other types of connectors that can be electrically connected, and can also be a device for implementing the speaker function or the image capturing function on the electronic device.
[0026] The above-mentioned shielding cover 10 can be used to shield the electrical signals on the functional element 30 to reduce the interference of the electrical signals of the functional element 30 on other functional devices such as the antenna structure of the electronic device. Moreover, the shielding cover 10 can also reduce the interference of the electromagnetic signals of other functional devices of the electronic device on the functional element 30.
[0027] The above metal reinforcement plate 32 can be understood as a reinforcement structure for strengthening the structural strength of the functional element 30. By enhancing the structural strength of the functional element 30, the stability of the functions realized by the functional element 30 is further improved.
[0028] In this embodiment, by providing the first conducting member 50 and electrically connecting the top 11 of the shielding cover 10 and the metal reinforcement plate 32 through the first conducting member 50, it is possible to avoid the interference signal generated in the gap 40 between the top 11 of the shielding cover 10 and the metal reinforcement plate 32, that is, it is possible to avoid the interference effect of the interference signal generated in the gap 40 on other functional elements of the electronic device, thereby improving the device performance of the electronic device.
[0029] In some embodiments, the electronic device further includes an antenna structure, and the antenna structure is disposed adjacent to the functional element 30.
[0030] In this embodiment, when an antenna structure is provided adjacent to the functional element 30, by providing the first conducting member 50 that electrically connects the top 11 of the shielding cover 10 and the metal reinforcement plate 32, it is possible to avoid the interference signal generated in the gap 40 between the top 11 of the shielding cover 10 and the metal reinforcement plate 32. Furthermore, it is possible to avoid the interference effect of the interference signal generated based on the shielding cover 10 on the antenna structure, thereby achieving the purpose of improving the radiation performance of the antenna structure and enhancing the radiation performance of the antenna structure.
[0031] The above first conducting member 50 can be a metal elastic sheet or a conductive foam or other conducting structures with certain elastic ability. By setting the first conducting member 50 as a conducting structure with certain elastic ability, the gap 40 between the top 11 of the shielding cover 10 and the metal reinforcement plate 32 can be filled to a certain extent, avoiding the generation of a resonant cavity and also avoiding the interference signal generated based on the gap 40.
[0032] In some embodiments, the electronic device further includes a shielding bracket 60, and the shielding bracket 60 is fixedly connected to the circuit board 20;
[0033] The shielding cover 10 is disposed on the circuit board 20 through the shielding bracket 60, and the top 11 of the shielding cover 10 and the metal reinforcement plate 32 are stacked in the thickness direction of the circuit board 20.
[0034] Among them, the above circuit board 20 can be understood as the main board structure of the electronic device.
[0035] Moreover, the structure formed by the shielding bracket 60 and the shielding cover 10 can be understood as the shielding structure of the electronic device.
[0036] In this embodiment, by providing the shielding bracket 60 and using the shielding bracket 60 to cover the shielding cover 10 on the functional element 30, the material cost of the side wall structure of the shielding cover 10 can be reduced.
[0037] In some embodiments, the shielding bracket 60 is provided with an opening 61, and one side of the top 11 of the shielding cover 10 facing the metal reinforcement plate 32 is exposed in the opening 61;
[0038] Wherein, one end of the first conducting member 50 is connected to the metal reinforcement plate 32, and the other end passes through the opening 61 and is connected to the top 11 of the shielding cover 10.
[0039] In this embodiment, by providing the opening 61 on the shielding bracket 60, one side of the top 11 of the shielding cover 10 facing the metal reinforcement plate 32 can be exposed in the opening 61, so that while one end of the first conducting member 50 is connected to the metal reinforcement plate 32, the other end can pass through the opening 61 and be connected to the top 11 of the shielding cover 10, thereby realizing that the first conducting member 50 can pass through the shielding bracket 60 and be connected to the top 11 of the shielding cover 10.
[0040] In some embodiments, the electronic device further includes an elastic preloading structure 70. The elastic preloading structure 70 is disposed in the gap 40, and the elastic preloading structure 70 abuts against the top 11 of the shielding cover 10 and the metal reinforcement plate 32 respectively.
[0041] In this embodiment, by providing the elastic preloading structure 70 and elastically connecting the top 11 of the shielding cover 10 and the metal reinforcement plate 32 by using the elastic preloading structure 70, the preloading effect of the top 11 of the shielding cover 10 on the functional element 30 can be further improved.
[0042] Moreover, since one side of the top 11 of the shielding cover 10 facing the metal reinforcement plate 32 can be exposed in the opening 61, the aperture size of the opening 61 can be set to set the cross-sectional sizes of the elastic preloading structure 70 and the first conducting member 50. For example, by increasing the aperture size of the opening 61, the cross-sectional area of the elastic preloading structure 70 can be increased, and thus the elastic preloading strength of the elastic preloading structure 70 can be increased.
[0043] In some embodiments, the body structure 31 may be a board-to-board connector, including a male connector 311 and a female connector 312. The male connector 311 is disposed on the circuit board 20, the female connector 312 is snapped onto the male connector 311, and the metal reinforcement plate 32 is disposed on the female connector 312.

[0045] In some embodiments, the first conducting member 50 may be a conducting member made of conductive foam, and the elastic preloading structure 70 may be a preloading structure made of insulating foam.
[0046] In some embodiments, a first clamping portion 62 is provided on the shielding bracket 60, and a second clamping portion 12 adapted to the first clamping portion 62 is provided on the shielding cover 10. Through the clamping cooperation of the first clamping portion 62 and the second clamping portion 12, the shielding cover 10 is disposed on the shielding bracket 60, improving the pre-fixing effect between the shielding cover 10 and the shielding bracket 60.
[0047] Among them, the first clamping portion 62 can be a circular hole structure provided on the shielding bracket 60, and the second clamping portion 12 can be a convex structure or a wave stud structure provided on the shielding cover 10.
[0048] In some embodiments, the first conducting member 50 and the shielding cover 10 are of an integral structure, which can improve the stability of the electrical connection between the top 11 of the shielding cover 10 and the metal reinforcing plate 32.
[0049] Among them, the first conducting member 50 and the shielding cover 10 being of an integral structure can be understood as an elastic connecting portion formed by the first conducting member 50 extending from the edge of the shielding cover 10.
[0050] As Figure 6 and Figure 7 shown, when the first conducting member 50 and the shielding cover 10 are of an integral structure, the first conducting member 50 can be understood as a spring piece structure formed by extending from the edge of the shielding cover 10.
[0051] As Figure 7 shown, the top 11 of the shielding cover 10 includes a first surface 111 and a second surface 112 which are arranged opposite to each other. The first surface 111 is the surface of the top 11 facing away from the metal reinforcing plate 32, and the second surface 112 is the surface of the top 11 facing the metal reinforcing plate 32.
[0052] The first conducting member 50 includes a first connecting section 51 and a second connecting section 52. The first connecting section 51 is a transition structure formed by extending from the edge of the top 11 of the shielding cover 10 to the side where the second surface 112 is located, and the bending angle between the first connecting section 51 and the edge of the top 11 is about 180°; the second connecting section 52 is a spring piece connecting section formed by extending from the end of the first connecting section 51. In this way, through the first conducting member 50 which is of an integral structure with the shielding cover 10, the electrical connection between the shielding cover 10 and the metal reinforcing plate 32 is realized, and the interference signal generated by the gap 40 between the top 11 of the shielding cover 10 and the metal reinforcing plate 32 can be avoided, that is, the interference signal generated by the gap 40 on other functional elements of the electronic device can be avoided, improving the device performance of the electronic device.
[0053] In some embodiments, the electronic device further includes a circuit board bracket 90. The circuit board bracket 90 includes a plastic bracket body 91 and a metal bracket 92 disposed within the plastic bracket body 91. The metal bracket 92 is stacked relative to the top cover 11 of the shielding cover 10, and the top cover 11 of the shielding cover 10 is located between the metal bracket 92 and the metal reinforcement plate 32.
[0054] The electronic device further includes a second conducting member, and the top cover 11 of the shielding cover 10 and the metal bracket 92 are electrically connected through the second conducting member.
[0055] In this embodiment, the above-mentioned metal bracket 92 may be a steel sheet structure disposed within the plastic bracket body 91, which is used to enhance the structural strength of the circuit board bracket 90. Moreover, by providing the second conducting member, the interference effect of the dielectric space between the top cover 11 of the shielding cover 10 and the metal bracket 92 on the antenna structure can be reduced.
[0056] In some embodiments, the circuit board bracket 90 may be disposed on the circuit board 20 by means of screw connection or the like.
[0057] In some embodiments, the electronic device further includes a second conducting member, and the top cover 11 of the shielding cover 10 and the metal bracket 92 are electrically connected through the second conducting member.
[0058] In this embodiment, by providing the second conducting member, the interference effect of the dielectric space formed between the top cover 11 of the shielding cover 10 and the metal bracket 92 on the antenna structure can be reduced.
