It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
[0033] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0034] With the development of communication technology, electronic devices such as tablet computers and notebook computers have become increasingly popular. The competition among major international well-known terminal manufacturers has become white-hot and the fields have become diversified. In addition to meeting the basic needs of users, the standardization of component design and the reduction of material costs have gradually become the key points for major terminal manufacturers to compete.
[0035] In the structural design of the terminal, due to design limitations, the main board and the secondary board of the electronic device are respectively located in the upper and lower parts of the electronic device, separated by the battery space in the middle. The screen connector for electrically connecting to the screen is located in the lower part of the electronic device. The screen flexible circuit board needs to be wound around the back side of the screen. One end of the screen flexible circuit board is electrically connected to the main board, and the other end is electrically connected to the screen connector.
[0036] However, the electrical connection between the screen flexible circuit board and the screen connector is generally achieved by electrically connecting the screen flexible circuit board and the screen connector to the secondary board respectively. Therefore, the secondary board needs to provide connection positions for them, resulting in a larger area and cost of the secondary board.
[0037] In order to solve the above technical problems, the present application provides an electronic device, which includes a front shell assembly 100 and a rear shell, and the rear shell is detachably connected to the front shell assembly 100. Specifically, the rear shell can be snap-connected to the front shell assembly 100.
[0038] Among them, please refer to Figures 1 to 3 , the front shell assembly 100 may include a middle frame 110, a connector 120, a main board, a secondary board 130, a display screen and a screen flexible circuit board 140. The main board and the secondary board 130 are important integral parts inside the mobile phone. The main board, as the "central hub", connects and controls the work of each part of the mobile phone; while the secondary board 130 enhances the performance and convenience of the mobile phone by providing additional storage space, interfaces and other functions. The two work together to ensure the normal operation of the mobile phone and the realization of various functions.
[0039] Specifically, the middle frame 110 includes a first surface and a second surface 112 which are opposite to each other in the thickness direction of the middle frame 110, the rear shell cover is arranged on the second surface 112, the second surface 112 is provided with a mainboard placement area 1221, a sub-board placement area 1222 and a battery placement area 1223, and in the length direction of the middle frame 110, the battery placement area 1223 is located between the mainboard placement area 1221 and the sub-board placement area 1222, the mainboard is placed in the mainboard placement area 1221, the sub-board 130 is placed in the sub-board placement area 1222, and the battery placement area 1223 is used to place the battery.
[0040] See also Figure 2 The connector 120 is also arranged in the sub-board placement area 1222, and the connector 120 includes a first connection end and a second connection end; the sub-board 130 includes a mounting notch 131, and the projection of the connector 120 on the second surface 112 is located within the projection of the mounting notch 131 on the second surface 112, that is, the connector 120 is arranged on the middle frame 110, and the mounting notch 131 of the sub-board 130 avoids the connector 120, and at the same time, the area of the sub-board 130 can be smaller, which can improve the panel utilization rate of the sub-board 130, save costs, and thus reduce the cost of electronic equipment.
[0041] The display screen is arranged on the first surface of the middle frame 110 and is electrically connected to the first connection end; the screen flexible circuit board 140 is located on the side where the second surface 112 of the middle frame 110 is located, and the screen flexible circuit board 140 includes a first end 141 and a second end 142, the first end 141 is electrically connected to the mainboard, and the second end 142 is electrically connected to the second connection end. Thus, by arranging the screen flexible circuit board 140 and the connector 120, the electrical connection between the display screen and the mainboard is realized.
[0042] In some embodiments of this application, please continue to refer to Figure 2 The sub-board placement area 1222 may include a first area 1224 and a second area 1225.

The second area 1225 protrudes from the first area 1224, and the installation notch 131 is stuck on the circumferential outer side of the second area 1225. The second area 1225 can provide positioning for the installation of the sub-board 130.
[0043] Specifically, the height by which the second region 1225 protrudes from the first region 1224 is the first height, and the thickness of the auxiliary plate 130 is the first thickness, and the first height is equal to the first thickness. In this way, while the second region 1225 provides positioning for the installation of the auxiliary plate 130, the height of the second region 1225 is the same as the height after the auxiliary plate 130 is installed on the first region 1224. Furthermore, the set height of the connector 120 can be ensured to be the same as that of the prior art. Furthermore, it is ensured that, without changing the specifications of the screen flexible circuit board 140, the electrical connection of the connector 120 can still be satisfied, and the design changes of other components in the electronic device are reduced.
[0044] It should be noted that in the prior art, the connector is arranged on the auxiliary plate, while in some embodiments of the present application, by raising the height of the second region 1225 to be equal to the thickness of the auxiliary plate 130, the adaptive changes of other components are reduced. While achieving a reduction in the area of the auxiliary plate 130, the cost of redesigning and arranging the remaining components is reduced.

The auxiliary flexible circuit board 150 passes through the mounting hole 113, and the fourth end 152 is arranged in the second region 1225. Thus, by providing the mounting hole 113, the required set length of the auxiliary flexible circuit board 150 can be reduced, and the layout of the auxiliary flexible circuit board 150 is simplified.
[0047] In some embodiments of the present application, the second region 1225 is provided with a mounting groove. The mounting groove is recessed from a partial surface of the second region 1225 towards the first surface, and the fourth end 152 is arranged in the mounting groove. Thus, by providing the mounting groove, a mounting position is provided for the fourth end 152.
[0048] Among them, the mounting groove can be arranged on the periphery of the mounting hole 113.
[0049] In some embodiments of the present application, the bottom wall of the mounting groove is provided with a positioning post 1141, and the fourth end 152 is provided with a positioning notch 1521 that cooperates with the positioning post 1141. In this way, by providing the mutually cooperating positioning notch 1521 and positioning post 1141, the fourth end 152 is positioned.
[0050] Among them, there can be multiple positioning posts 1141 and multiple positioning notches 1521, and the number of positioning posts 1141 corresponds one-to-one with the number of positioning notches 1521.
