[0039] Referring to Figures 1 to 4 , an embodiment of the present application provides a rotating shaft 10, which can realize the relative rotation between two electronic devices electrically connected through a flexible cable 40. The two electronic devices are a first electronic device and a second electronic device respectively, and the rotating shaft 10 includes a first rotating member 11 and a second rotating member 12 that are rotatably connected.

[0040] Specifically, the first rotating member 11 can be connected to the first electronic device. One end of the first rotating member 11 is provided with a first accommodation cavity 110 along the axial direction of the first rotating member 11, and a first side opening 1101 communicating with the first accommodation cavity 110 is provided on the side surface of the first rotating member 11. The first side opening 1101 is arranged on the side of the first rotating member 11 close to the first electronic device. The second rotating member 12 can be connected to the electronic device. One end of the second rotating member 12 is provided with a second accommodation cavity 120 along the axial direction of the second rotating member 12, and a second side opening 1201 communicating with the second accommodation cavity 120 is provided on the side surface of the second rotating member 12.

The rotation axis direction of the first rotating member 11 relative to the second rotating member 12 is the same as the axial direction of the first rotating member 11 and the axial direction of the second rotating member 12.

[0043] The rotating shaft 10 of the present application includes a first rotating member 11 and a second rotating member 12.

This setting not only effectively optimizes the overall structure of the device including two electronic devices, is beneficial to the miniaturization design of the device, but also can protect the flexible cable 40 through the rotating shaft 10, avoid damage to the flexible cable 40 during the rotation process, and ensure the overall service life of the device.

[0044] In some embodiments of the present application, both the first rotating member 11 and the second rotating member 12 can be set into a rod-shaped structure. The first rotating member 11 can be connected to the first electronic device, and the second rotating member 12 can be connected to the second electronic device.

[0045] One end of the first rotating member 11 provided with the first accommodating cavity 110 penetrates through one end of the second rotating member 12 provided with the second accommodating cavity 120, and the end of the second rotating member 12 is rotatably sleeved on the end of the first rotating member 11, so that the first rotating member 11 can rotate relative to the second rotating member 12.

[0046] Specifically, one end of the first rotating member 11 can protrude outward along its own axis direction to form a connecting boss 13, the connecting boss 13 penetrates through one end of the second rotating member 12, and the connecting boss 13 can rotate at the end of the second rotating member 12 to realize the relative rotation of the first rotating member 11 and the second rotating member 12.

[0047] In other examples, it can also be set that one end of the second rotating member 12 provided with the second accommodating cavity 120 penetrates through one end of the first rotating member 11 provided with the first accommodating cavity 110, and the end of the first rotating member 11 is rotatably sleeved on the end of the second rotating member 12, so that the second rotating member 12 can rotate relative to the first rotating member 11.

[0048] That is, one end of the second rotating member 12 can protrude outward along its own axis direction to form a connecting boss 13, the connecting boss 13 penetrates through one end of the first rotating member 11, and the connecting boss 13 can rotate at the end of the first rotating member 11 to realize the relative rotation of the first rotating member 11 and the second rotating member 12.

[0049] Refer to Figure 3 and Figure 4 In some embodiments of the present application, the first rotating member 11 may include a connected first main body portion 111 and a first positioning portion 112, and both the first main body portion 111 and the first positioning portion 112 may be rod-shaped structures. The axis direction of the first main body portion 111 is the same as the axis direction of the first positioning portion 112, and is the same as the axis direction of the first rotating member 11.

[0050] The second rotating member 12 is connected to a second main body portion 121 and a second positioning portion 122, and both the second main body portion 121 and the second positioning portion 122 may be rod-shaped structures. The axis direction of the second main body portion 121 is the same as the axis direction of the second positioning portion 122, and is the same as the axis direction of the second rotating member 12.

[0051] Wherein, the first accommodating cavity 110 is arranged on the first main body portion 111, and the second accommodating cavity 120 is arranged on the second main body portion 121. One end of the first main body portion 111 is connected to one end of the second main body portion 121, so that the first accommodating cavity 110 and the second accommodating cavity 120 are connected to form an accommodating space 1001.

[0052] A first side opening 1101 is provided on the side surface of the first main body portion 111, and the first side opening 1101 communicates with the first accommodation cavity 110. A second side opening 1201 is provided on the side surface of the second main body portion 121, and the second side opening 1201 communicates with the second accommodation cavity 120. The flexible flat cable 40 is disposed in the accommodation space 1001. One end of the flexible flat cable 40 extends out from the first side opening 1101, and the other end of the flexible flat cable 40 extends out from the second side opening 1201.

[0053] In this embodiment, the first positioning portion 112 can be connected to the second electronic device, and the second positioning portion 122 can be connected to the first electronic device. The rotating shaft 10 is connected to the two electronic devices through the first positioning portion 112 and the second positioning portion 122, and both ends of the flexible flat cable 40 are connected to the two electronic devices respectively to realize the electrical connection between the two electronic devices.

[0054] The first accommodation cavity 110 of the first main body portion 111 and the second accommodation cavity 120 of the second main body portion 121 can provide an installation position for the flexible flat cable 40. There is no need to provide an additional installation structure to assemble the flexible flat cable 40. Only through the rotating shaft 10 can the flexible flat cable 40 be protected to avoid damage to the flexible flat cable 40 during the rotation process and ensure the overall service life of the device.

[0055] In this embodiment, the first positioning portion 112 is rotatably connected to the first main body portion 111 about the axis direction of the first rotating member 11, and the second positioning portion 122 is rotatably connected to the second main body portion 121 about the axis direction of the second rotating member 12. The first positioning portion 112 rotates relative to the first main body portion 111, and the second positioning portion 122 rotates relative to the first main body portion 111, so that the two electronic devices can rotate relative to each other.

[0056] In some examples, the end portion of the first positioning portion 112 is rotatably inserted into the end portion of the first main body portion 111, so that the first positioning portion 112 can rotate relative to the first main body portion 111; or, the end portion of the first positioning portion 112 is rotatably sleeved on the end portion of the first main body portion 111, so that the first positioning portion 112 can rotate relative to the first main body portion 111.

[0057] In some examples, the end portion of the second positioning portion 122 is rotatably inserted into the end portion of the second main body portion 121, so that the second positioning portion 122 can rotate relative to the second main body portion 121; or, the end portion of the second positioning portion 122 is rotatably sleeved on the end portion of the second main body portion 121, so that the second positioning portion 122 can rotate relative to the second main body portion 121.

[0058] In some embodiments of the present application, the rotating shaft 10 may further include a damping member. The setting of the damping member can achieve the positioning after the relative rotation of the two electronic devices, so that the two electronic devices rotate and are positioned at the included angle required by the user.

[0059] A damping member is provided between the first positioning portion 112 and the first main body portion 111. The damping member may be a layered structure made of a material with a high friction coefficient. The damping member is disposed at the connection between the first positioning portion 112 and the first main body portion 111 to provide frictional force when the first positioning portion 112 rotates relative to the first main body portion 111, so that the first positioning portion 112 and the first main body portion 111 are positioned and maintained at a set included angle position.

[0060] A damping member is provided between the second positioning portion 122 and the second main body portion 121. The damping member may be a layered structure made of a material with a high friction coefficient. The damping member is disposed at the connection between the second positioning portion 122 and the second main body portion 121 to provide frictional force when the second positioning portion 122 rotates relative to the second main body portion 121, so that the second positioning portion 122 and the second main body portion 121 are positioned and maintained at a set included angle position.

[0061] In some embodiments of the present application, relative rotation can also occur between the first main body portion 111 and the second main body portion 121. The axis direction of the relative rotation of the first main body portion 111 relative to the second main body portion 121 is the same as the axis directions of the first rotating member 11 and the second rotating member 12.

[0062] That is, relative rotation can occur between the first positioning portion 112 and the first main body portion 111, between the second positioning portion 122 and the first main body portion 111, and between the first main body portion 111 and the second main body portion 121. Such a setting makes the relative rotation of the two electronic devices more flexible, and makes the rotation between the first main body portion 111 and the second main body portion 121 more adaptable to the rotation displacement change between the two electronic devices, so as to reduce the damage to the flexible flat cable 40 inside the first main body portion 111 and the second main body portion 121, effectively protect the flexible flat cable 40, and ensure the normal and effective use of the flexible flat cable 40.

[0064] Specifically, the end of the first main body portion 111 can protrude outward along its own axis direction to form a connecting boss 13. The connecting boss 13 passes through the end of the second main body portion 121, and the connecting boss 13 can rotate at the end of the second main body portion 121 to achieve the relative rotation of the first main body portion 111 and the second main body portion 121.

[0065] In other examples, it can also be arranged that the end of the second main body portion 121 provided with the second accommodating cavity 120 passes through the end of the first main body portion 111 provided with the first accommodating cavity 110, and the end of the first main body portion 111 is rotatably sleeved on the end of the second main body portion 121, so that the second main body portion 121 can rotate relative to the first main body portion 111.

[0066] That is, the end of the second main body portion 121 can protrude outward along its own axis direction to form a connecting boss 13. The connecting boss 13 passes through the end of the first main body portion 111, and the connecting boss 13 can rotate at the end of the first main body portion 111 to achieve the relative rotation of the first main body portion 111 and the second main body portion 121.

[0067] In some embodiments of the present application, the first main body portion 111 and the second positioning portion 122 are connected to the same electronic device, and the second main body portion 121 and the first positioning portion 112 are connected to the same electronic device.

[0068] Wherein, the first rotating member 11 further includes a first fixing portion 113, and the second rotating member 12 further includes a second fixing portion 123. Both the first fixing portion 113 and the second fixing portion 123 are plate-shaped, and a first fixing hole 114 is provided on the first fixing portion 113. A second fixing hole 124 is provided on the second fixing portion 123.

[0069] The first fixing portion 113 is provided on both the outer side of the first positioning portion 112 and the outer side of the first main body portion 111. The first positioning portion 112 is connected to one of the electronic devices through the first fixing portion 113 on its outer side, and the first main body portion 111 is connected to the other electronic device through the first fixing portion 113 on its outer side.

[0070] The rotating shaft 10 may further include a fastener. The fastener passes through the first fixing hole 114 and the mounting hole of the electronic device, so that the first main body portion 111 and the first positioning portion 112 are respectively connected to the two electronic devices.

[0071] The second fixing portion 123 is provided on both the outer side of the second positioning portion 122 and the outer side of the second main body portion 121. The second positioning portion 122 is connected to one of the electronic devices through the second fixing portion 123 on its outer side, and the second main body portion 121 is connected to the other electronic device through the second fixing portion 123 on its outer side.

[0072] The rotating shaft 10 may further include a fastener which passes through the second fixing hole 124 and the mounting hole of the electronic device, so that the second main body portion 121 and the second positioning portion 122 are respectively connected to two electronic devices.

[0073] The fastener may be a screw or a pin, or other fastening connection structures that can fix the first fixing portion 113, the second fixing portion 123 and the electronic device. In other examples, the first fixing portion 113 and the second fixing portion 123 may also be connected to the electronic device in other forms, such as by snap connection, interference fit, magnetic attraction fixation, etc.

[0074] In some embodiments of the present application, the first fixing portion 113 on the first main body portion 111 and the first side opening 1101 are located in the same extending direction on the side surface of the first rotating member 11, and the second fixing portion 123 on the second main body portion 121 and the second side opening 1201 are located in the same extending direction on the side surface of the second rotating member 12. This setting makes the connection positions of the two ends of the flexible cable 40 and the two electronic devices and the connection positions of the first main body portion 111, the second main body portion 121 and the two electronic devices are arranged on the same plane on both sides of the rotating shaft 10, avoiding excessive pulling of the flexible cable 40 caused by the relative rotation of the two electronic devices, and ensuring the stability of the overall structure of the flexible cable 40.

[0075] In some other embodiments of the present application, only the rotational setting of the first positioning portion 112 relative to the first main body portion 111 and the rotational setting of the second positioning portion 122 relative to the second main body portion 121 may be retained in the rotating shaft 10, and the rotation of the first main body portion 111 relative to the second main body portion 121 need not be provided. At this time, only the first fixing portion 113 is provided outside the first positioning portion 112 and the second fixing portion 123 is provided outside the second positioning portion 122.

[0076] The first main body portion 111 and the second main body portion 121 arranged in this way provide an installation position for the flexible cable 40, and the first positioning portion 112 and the second positioning portion 122 realize the relative rotation of the two electronic devices, which can simplify the overall structure of the rotating shaft 10 and is beneficial to the realization of the miniaturization and lightweight design of the electronic device.

[0077] In other embodiments of the present application, only the first main body portion 111 and the second main body portion 121 may be retained in the rotating shaft 10, and the first positioning portion 112 and the second positioning portion 122 are omitted. The first main body portion 111 can rotate relative to the second main body portion 121.
