Technical Field

The present application relates to a waterproof electronic device.

Background

Folding mobile phones with foldable screens are becoming more common, and various manufacturers have proposed a number of folding mobile phones with foldable screens. The connection of the circuit boards in the middle frames on both sides of the folding mobile phone is usually achieved by one or several flexible circuit boards (Flexible Printed Circuit, abbreviated as FPC) penetrating the corresponding middle frames to transmit information. Because the middle of the folding mobile phone is connected by the rotating shaft, the FPC needs to bypass the rotating shaft, so the FPC is also called a shaft penetrating FPC. If water enters the position where the through-shaft FPC passes through the middle frame, the use of the folding mobile phone can be directly affected, so that the waterproof design is needed.

The first circuit board is mounted in the first middle frame 10, and the second circuit board is mounted in the second middle frame 20. In the second direction (shown in the X direction in fig. 1), the rotation shaft is located between the board first accommodation chamber 11 and the board second accommodation chamber 21 (the specific position will be described later).

Illustratively, the second direction shown in fig. 1 is, for example, the width direction of the folding cellular phone 1, and the first middle frame 10 and the second middle frame 20 of the folding cellular phone 1 can be rotated left and right about the rotation axis in the width direction to put the folding cellular phone 1 in the folded state and the unfolded state (the state shown in fig. 1).

As shown in fig. 4, fig. 4 shows a cross-sectional view of the folded mobile phone 1 according to one embodiment of the present application from a side view. Fig. 5 shows an enlarged view of the portion B in fig. 4.

Referring to fig. 3 and 5, the first and second middle frames 10 and 20 are oppositely disposed in a second direction (shown in an X direction in fig. 3 and 5) to form a rotation shaft receiving space V1, and the rotation shaft receiving space V1 extends in a first direction (shown in a Y direction in fig. 3). The first housing chamber 11 and the second housing chamber 21 are adjacent to the shaft housing space V1. That is, the above-described board first accommodation chamber 11 and board second accommodation chamber 21 are adjacent to the rotation shaft, respectively. That is, in the second direction, the shaft accommodating space V1 is located between the board first accommodating chamber 11 and the board second accommodating chamber 21. The above-mentioned rotating shaft extends along the first direction and is installed in the rotating shaft accommodating space V1, and the first middle frame 10 and the second middle frame 20 are rotatably connected through the rotating shaft.

With continued reference to fig. 3 and 5, the circuit board first accommodating chamber 11 includes a first side wall 111 adjacent to the rotating shaft accommodating space V1 and a first bottom wall 112 adjacent to the first side wall 111, and the first side wall 111 is provided with a first hole 113 at a connection with the first bottom wall 112. Illustratively, the first side wall 111 extends in the thickness direction (shown in the Z direction in fig. 5) of the folded handset 1, the first side wall 111 being perpendicular to the first bottom wall 112. The overall shape of the first side wall 111 and the first bottom wall 112 is L-shaped. The circuit board second accommodating cavity 21 includes a second side wall 114 adjacent to the rotating shaft accommodating space V1 and a second bottom wall 212 adjacent to the second side wall 211, and the second side wall 211 is provided with a second hole 213 at a connection with the second bottom wall 212. Illustratively, the second side wall 211 extends in the thickness direction (shown in the Z direction in fig. 5) of the folded handset 1, the second side wall 211 being perpendicular to the second bottom wall 212. Equivalently, the overall shape of the second side wall 114 and the second bottom wall 212 is L-shaped.

As shown in fig. 3 and 5, one flexible circuit board 30 spans the rotation axis and is electrically connected to the first circuit board in the first middle frame 10 through the first hole 113 and is electrically connected to the second circuit board in the second middle frame 20 through the second hole 213. The number of the flexible circuit boards 30 is not limited, and the flexible circuit boards 30 with corresponding numbers, such as two, three, etc., are set according to the transmission information requirement of the circuit boards.

As shown in fig. 5, the above-described flexible wiring board 30 includes a left side portion 31, a middle portion 32, and a right side portion 33. The left side portion 31 of the flexible circuit board 30 passes through the first hole 113 of the first middle frame 10 and is accommodated in the circuit board first accommodating cavity 11, the right side portion 33 of the flexible circuit board 30 passes through the second hole 213 of the second middle frame 20 and is accommodated in the circuit board second accommodating cavity 21, and the middle portion 32 of the flexible circuit board 30 is positioned in the rotating shaft accommodating space V1 and bypasses the rotating shaft.

Illustratively, the middle portion 32 of the flexible wiring board 30 is in an omega shape, and the middle portion 32 of the omega-shaped flexible wiring board 30 forms a rotation shaft bypass space V2, the rotation shaft bypass space V2 being smaller than the rotation shaft accommodation space V1. The rotation shaft bypasses the space V2, i.e., the position where the flexible wiring board 30 bypasses the rotation shaft. That is, the rotation shaft is located in the rotation shaft bypass space V2.

If water enters the position where the through-shaft flexible circuit board 30 passes through the middle frame, the use of the folding mobile phone 1 is directly affected, so that a waterproof design is required. Because the shaft is a movable member, it is difficult to achieve waterproofing particularly at the shaft ends (both ends in the first direction). Meanwhile, the posture and position of the through-shaft flexible circuit board 30 passing through the middle frame determine the special opening structure (L-shape) of the first hole 113 and the second hole 213, which is greatly different from the conventional waterproof structure.

For this purpose, the present application transfers the waterproof design to the location where the flexible circuit board passes through the holes of the middle frame. The application provides a waterproof scheme for coping with shaft penetration of a flexible circuit board. In this scheme, waterproof through setting up shutoff portion in the hole department of corresponding center for folding mobile phone's waterproof ability obtains promoting.

The structure of the blocking portion and a specific waterproofing scheme are described in detail below with reference to the accompanying drawings.

The first blocking portion 40 is installed in the first accommodating cavity 11 of the circuit board of the first middle frame 10, and is used for blocking the first hole 113 in the state that the flexible circuit board 30 passes through the first hole 113 shown in fig. 3 and 5. After the first blocking portion 40 blocks the first hole 113, the first hole 113 achieves a waterproof seal, and water cannot flow from one side of the first sidewall 111 of the first middle frame 10 to the opposite side through the first hole 113. For example, water cannot flow from the outside of the first middle frame 10 into the inside of the first middle frame 10 through the first hole 113.

The second blocking portion 50 is installed in the circuit board second accommodating cavity 21 of the second middle frame 20, and is used for blocking the second hole 213 in the state that the flexible circuit board 30 passes through the second hole 213 as shown in fig. 3 and 5. After the second blocking portion 50 blocks the second hole 213, the second hole 213 is sealed in a waterproof manner, and water cannot flow from one side of the sidewall of the second middle frame 20 to the opposite side through the second hole 213. For example, water cannot flow from the outside of the second middle frame 20 into the inside of the second middle frame 20 through the second hole 213.

The first blocking part 40 and the second blocking part 50 are used for blocking holes (the first hole 113 and the second hole 213) at the corresponding middle frames (the first middle frame 10 and the second middle frame 20) of the folding mobile phone 1, so that the waterproof effect on the special hole structure is realized.
