As shown in fig. 1A and 1B, the hinge of the embodiment of the present disclosure may be applied to a tablet pc 100, which may include a body 110 and a bracket 120, wherein a display screen may be disposed on a front surface of the body 110, a rear surface of the body 110 may have a step shape, and a left half portion of the rear surface may have a boss 111, so that the left half portion of the body 110 may have a larger thickness than a right half portion thereof. The bracket 120 may be disposed on the back of the body 110 and matched with the lower half of the body 110, and when the bracket 120 is closed to the back of the body, the surface of the bracket 120 is approximately coplanar with the surface of the boss 111, so that the tablet computer has a relatively flat back.

The rotation shaft 130 is connected between the bracket 120 and the body 110 so that the bracket 120 can rotate relative to the body 110. If the rotating shaft 130 is a conventional rotating shaft having a solid central axis, the position of the solid central axis relative to the body 110 is not changed during the rotation of the bracket 120, and the bracket 120 gradually gets away from the boss 111 during the rotation back to the back of the body 110 around the solid central axis, and when the bracket 120 rotates back to the back of the body 110, a large gap is left between the bracket 120 and the boss 111, which affects the appearance.

The pivot of this disclosed embodiment adopts virtual axle form, and the pivot of virtual axle form is different with traditional pivot: the conventional rotating shaft is generally provided with a solid central shaft and two connecting parts rotating around the solid shaft, the rotating center is the axis of the solid shaft, the rotating shaft center of the virtual shaft is not a solid shaft but a virtual central shaft, the moving track of the connecting parts is arc-shaped, so that the support 20 can move while rotating, and the support 120 can move in the direction gradually approaching the boss 111 during the rotating process. As shown in fig. 1B, when the bracket 120 is closed, the bracket 120 can be attached to the boss 111, and the gap between the bracket 120 and the boss is small, so that the aesthetic property of the electronic device is improved.

When the slider of the rotating part 132 slides to the right end of the guide rail 133, the rotating part 132 forms a certain angle with the base 131, and at this time, the bracket forms a certain angle with the body; when the slider slides to the left end of the guide rail 133, the support is accommodated to the back of the body, and because the rotating part 132 slides a distance to the left side relative to the base 131 in the sliding process of the slider from the right end of the guide rail to the left end, the support also slides a distance to the left side relatively, and when the support is restored to the back of the body, the support can be close to the boss on the back of the body, and a gap between the support and the body is reduced. The directions of up, down, left, right, and the like mentioned in the embodiments of the present disclosure are all the directions shown in the corresponding drawings, and are only for convenience of description, and are not used to limit the embodiments of the present disclosure.

However, the width W of the virtual shaft structure of the double guide rail is wide, and the width W is more than 8mm, and in order to reduce the width of the rotating shaft, the embodiment of the present disclosure also provides a rotating shaft in the form of a virtual shaft of a single guide rail, and the structure of the rotating shaft of the single guide rail is described below.

It is understood that the application scenarios in fig. 1A and 1B are only an example, and the hinge can be applied to a tablet computer, but also to other devices having two bodies that need to rotate relatively, such as a notebook computer.

As shown in fig. 3A and 3B, according to an embodiment of the present disclosure, the first connection plate 211 is provided with a connection hole 2111, and the connection member 230 is fixedly connected to the connection hole 2111.

The manner of fixing the connection member 230 to the connection hole 2111 may be, for example: the area of the connecting member 230 corresponding to the connecting hole 2111 is matched with the shape of the connecting hole 2111, and the area of the connecting member 230 and the connecting hole 2111 are both non-circular, for example, the area of the connecting member 230 is square, the connecting hole 2111 is also square, and the area of the connecting member 230 is matched with the size of the connecting hole 2111, so that the first connecting plate 211 can drive the connecting member 230 to move.

For example, the connector 230 may resemble a bolt, the connector 230 having a fixedly connected head and a post, wherein the head is larger in size than the post, and the end of the post is provided with external threads. The head of the connector 230 abuts against the outer surface of the first connection plate 211, and the end of the cylinder passes through the connection hole 2111 and protrudes from the inner surface of the first connection plate 211.

Fig. 5A, 5B, and 5C schematically illustrate rotation of the first component 210 relative to the second component 220, wherein fig. 5B and 5C do not illustrate fasteners, according to an embodiment of the disclosure.

As shown in fig. 5A, 5B and 5C, during the rotation of the first part 210 relative to the second part 220, the first rail structure 212 slides along the second rail structure 222, and the first connecting plate 211 drives the connecting member 230 to move in the sliding slot 223.

For example, when the first portion 210 rotates under the action of an external force, the first rail structure 212 slides along the second rail structure 222, the first rail structure performs a circular arc motion, the first connecting plate 211 performs a circular arc motion as the first rail structure is fixedly connected with the first connecting plate 211, and the connecting member 230 follows the first connecting plate 211 to perform a circular arc motion as the first connecting plate 211 is fixedly connected with the connecting member 230, and the connecting member 230 can move in the sliding slot 223 as the connecting member 230 is located in the sliding slot 223.

Based on the above structure, when the bracket of the tablet computer has the largest included angle with the body, the connecting member 230 is located at the right end of the sliding slot 223. When the bracket rotates back to the back of the body from the maximum included angle, the connecting piece 230 slides from the right end to the left end of the sliding slot 223, so that the first part 210 can move to the left relative to the second part 220, and accordingly, the bracket can be closer to the boss on the left side of the body in the rotating process until the connecting piece 230 slides to the left end of the sliding slot 223, and at the moment, the bracket rotates back to the back of the body, and the gap between the bracket and the boss is small.

According to the embodiment of the disclosure, the first guide rail structure and the connecting piece are arranged on the first part of the rotating shaft, and the second guide rail structure and the sliding groove hole are arranged on the second part, so that the first part can do arc motion relative to the second part, and two bodies respectively connected with the first part and the second part can have a tiny gap when being aligned. The coupling member and fastener cooperate to provide resistance to rotation so that the first portion can be locked at an angle relative to the second portion. In addition, the rotating shaft in the single guide rail form provided by the embodiment of the disclosure can reduce the width of the rotating shaft and reduce the transverse occupied space.

As shown in fig. 5A, according to the embodiment of the present disclosure, in the case that the connection member 230 is located at the first end of the slide slot hole, which may be, for example, the left end as shown, the first mounting plate 213 and the second mounting plate 224 are parallel, the first mounting plate 213 and the second mounting plate 224 are respectively located at both sides of the connection member, and the included angle between the first mounting plate 213 and the second mounting plate 224 is 0 °.

The slide groove hole 223 has a circular arc shape, and the corresponding central angle of the slide groove hole 223 defines the maximum angle at which the first mounting plate 213 can rotate relative to the second mounting plate 224.

Fig. 6A schematically illustrates a schematic view of a corresponding central angle of a sliding slot hole according to an embodiment of the disclosure.

As shown in fig. 6A, according to the embodiment of the present disclosure, the central angle α corresponding to the sliding slot hole 223 may belong to a first angle range, that is, the central angle corresponding to the sliding slot hole 223 may be any one of the first angle ranges, wherein the first angle range may be, for example, 40 ° to 150 °. In the case where the link 230 is located at the second end of the slide slot aperture 223, which may be, for example, the right end as shown in fig. 6A, the first mounting plate 213 and the second mounting plate 224 are at the maximum included angle. For example, the first angular range may be, for example, 60 ° and the first mounting plate 213 may be rotatable relative to the second mounting plate 224 between 0 ° and 60 °, up to 60 °. In this case, the angle at which the first mounting plate 213 can be rotated with respect to the second mounting plate 224 is within a small range, and this structure can be applied to the body and the stand of the tablet computer.

As shown in fig. 6B, the central angle β corresponding to the sliding slot aperture 223 may be any angle in a second angle range, wherein the second angle range includes angles larger than those included in the first angle range, and the second angle range may be, for example, 180 ° to 250 °. The structure can be suitable for the notebook computer with double-sided screens, namely, the two bodies of the notebook computer are both provided with the display panels, and the two bodies of the notebook computer can be respectively and fixedly connected with the first part and the second part of the rotating shaft.

In the case where the connection member 230 is located at the second end of the slide groove hole 223, wherein the second end of the slide groove hole 223 may refer to, for example, the upper end as shown in fig. 6B, the first mounting plate 213 and the second mounting plate 224 are located on the same side of the connection member 230, and the first mounting plate 213 and the second mounting plate 224 are parallel, the first mounting plate 213 and the second mounting plate 224 are stacked up and down, and at this time, the first body and the second body of the notebook computer fixedly connected to the first mounting plate 213 and the second mounting plate 224, respectively, may be closed together. In the case that the connecting member 230 is located at the first end of the sliding slot 223, wherein the first end of the sliding slot 223 may refer to the lower end of the drawing, for example, the first mounting plate 213 and the second mounting plate 224 are located at different sides of the connecting member 230, and the first mounting plate 213 and the second mounting plate 224 are parallel, at this time, the first body and the second body of the notebook computer fixedly connected to the first mounting plate 213 and the second mounting plate 224 respectively are unfolded to 180 °, that is, the first body and the second body of the notebook computer are unfolded to form a flat angle, and the display panels of the first body and the second body face to the same side, so that a user can view two screens at the same time, and at this time, the gap between the first body and the second body is extremely small, thereby the distance between the two display panels can be very small, and the screen crossing operation is convenient to be performed.
