Next, please refer to FIG. 2A and FIG. 2B together. The aforementioned second pivotal portion 401 is pivotally connected to the first pivotal portion 302 on the right side of the body 30, and the second pivotal portion 401 is connected to the body 30 through the pivotal mechanism R at the same time. The first pivot portion 301 on the left side is pivotally connected. As shown in FIG. 2A, the aforementioned pivot mechanism R mainly includes a first pivot R1 and a second pivot R2, wherein the first pivot R1 is fixed in the second pivot 401, and the second pivot The component R2 is fixed in the first pivot portion 301 on the left side of the main body 30 . In this embodiment, the aforementioned first and second pivot members R1 and R2 are hollow structures and are rotatably nested with each other, so that the main body 30 and the flip cover 40 can be pivotally connected through the pivot mechanism R and Relatively rotatable (as shown by the arrow in Fig. 2B).

In FIGS. 2A and 2B , the aforementioned flexible printed circuit F sequentially passes through the first pivotal portion 302 on the right side of the body 30 and the second pivotal portion 401 below the flip cover 40 to electrically connect the body 30 And flip cover 40. On the other hand, since the aforementioned pivot mechanism R and the first and second pivot portions 301, 401 are hollow structures, the electrical connector C can pass through the first pivot portion 301, The pivot mechanism R and the second pivot portion 401 are used to electrically connect the main body 30 and the flip cover 40 . In particular, by making the electrical connector C and the flexible printed circuit board F respectively pass through the first pivot joints 301 and 302 on both sides of the body 30, the electrical connector C and the flexible printed circuit board F are both There will be no interference between them, and at the same time, mutual electromagnetic noise interference can be avoided.

Next, please refer to FIG. 3A and FIG. 3B together. These two figures show a schematic view of the combination of the pivot joint mechanism R and a positioning mechanism 50 in the present invention. As shown in the figure, the aforementioned foldable electronic device further includes a positioning mechanism 50 disposed inside the pivot mechanism R. As shown in FIG. The aforementioned pivot mechanism R is mainly composed of a first pivot piece R1 and a second pivot piece R2, wherein the first pivot piece R1 mainly includes a hollow tube R11 and a spacer R12, the spacer R12 The body 30 and the flip cover 40 are disposed inside the hollow tube R11 and generally extend toward a first axis X. The aforementioned body 30 and flip cover 40 are mutually rotatable around the first axis X through the pivot mechanism R. In this embodiment, the spacer R12 is mainly used to partition the interior of the hollow tube R11 to form a first space S1 and a second space S2 , wherein the second space S2 is larger than the first space S1 . In particular, one side of the aforementioned hollow tube body R11 has an annular flange R13, the outer diameter of the above-mentioned annular flange R13 is smaller than the outer diameter of the hollow tube body R11, wherein a ring-shaped flange R13 is provided with Opening hole R13'.

As shown in Figure 3A, the positioning mechanism 50 is arranged in the first space S1. The positioning mechanism 50 is mainly composed of an elastic member 501 and a spherical positioning member 502, wherein the elastic member 501 can be a shrapnel, but it can also be used springs or other elastic elements. In addition, the positioning member 502 is fixed in a groove 501' on the elastic member 501, thereby preventing the positioning member 502 from sliding relative to the elastic member 501. Then please refer to FIG. 3B , when assembled, the positioning member 502 is located at the opening R13' on the first pivot member R1, and the elastic member 501 abuts between the spacer R12 and the positioning member 502; due to the diameter of the positioning member 502 The hole diameter is larger than the opening R13 ′, so the elastic member 501 exerts an elastic force on the upper positioning piece 502 and can limit the positioning piece 502 in the opening R13 ′ to avoid falling off.

In particular, since the aforementioned positioning mechanism 50 is disposed in the first space S1 inside the first pivotal member R1, the electrical connector C passes through the second pivotal member R2 and the second space inside the first pivotal member R1 S2, therefore, the aforementioned positioning mechanism 50 and the electrical connector C can be blocked by the spacer R12 without interfering with each other.

Please refer to FIG. 5A and FIG. 5B together. When the second pivot member R2 rotates clockwise from the first position relative to the first pivot member R1 , the positioning member 502 disengages from the first groove R21 . As shown in FIG. 5B , since the positioning member 502 is still under the elastic force provided by the elastic member 501 at this time, the positioning member 502 is still continuously abutting against the inner surface of the second pivot member R2 .

Next, please refer to FIG. 6A and FIG. 6B together. When the second pivotal member R2 continues to rotate clockwise from the first position relative to the first pivotal member R1 to a second position, the positioning member 502 is elastically The elastic force of the component 501 pushes through the hole R13 ′, and protrudes outside the annular flange R13 . At this time, the positioning member 502 engages with a second groove R22 on the inner surface of the second pivot member R2 to limit the mutual rotation between the first and second pivot members R1 and R2 .

In this way, the aforementioned body 30 and flip cover 40 can have a positioning effect when they are rotated to a specific angle, wherein when the second pivot member R2 is in the first or second position relative to the first pivot member R1, The first and second grooves R21 and R22 on the inner surface of the second pivotal member R2 can be respectively engaged by the positioning member 502, thereby restricting the mutual rotation of the first and second pivotal members R1 and R2, and making the body 30 It forms a specific included angle with the flip cover 40 .

To sum up, the foldable electronic device of the present invention can not only be used to electrically connect the body 30 and Flipping the cover 40 can prevent interference between the electrical connector C and other wires and electromagnetic noise. In addition, in the foldable electronic device of the present invention, the positioning mechanism 50 can be provided inside the hollow pivot mechanism R, so that the main body 30 and the flip cover 40 can also have a positioning effect during the rotation process.
