Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

The following describes a spindle assembly according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 1, a spindle assembly according to an embodiment of the present invention includes: a base 1, a first rotating member 2, a connecting member 3, and a supporting member 4.

One end of the first rotating member 2 (e.g., the left end of the first rotating member 2 in fig. 1) is rotatably connected to the base 1, the connecting member 3 has a first supporting surface 31, the first supporting surface 31 refers to the upper surface of the connecting member 3 in fig. 2, the connecting member 3 is rotatably connected to the other end of the first rotating member 2 (e.g., the right end of the first rotating member 2 in fig. 1), the supporting member 4 has a second supporting surface 41, the second supporting surface 41 refers to the upper surface of the supporting member 4 in fig. 2, one end of the supporting member 4 (e.g., the right end of the supporting member 4 in fig. 1) is rotatably connected to the connecting member 3, the first rotating member 2 can rotate the supporting member 4 through the connecting member 3 between a first position and a second position, and the rotation direction of the first rotating member 2 relative to the base 1 coincides with the rotation direction of the supporting member 4 relative to the connecting member 3, in the first position, the first supporting surface 31 and the second supporting surface 41 are located in the same plane, and in the second position, the extending surface 41 of the first supporting surface 31 intersects with the extending surface 41 in the second position.

It will be appreciated that the first supporting surface 31 on the connecting member 3 and the second supporting surface 41 on the supporting member 4 are both used for supporting the screen, and in the first position, as shown in fig. 2, the first supporting surface 31 and the second supporting surface 41 are located on the same plane, which means that the screen is in a flattened state, and the supporting member 4 is lifted to support the screen; in the second position, as shown in fig. 3, the extending surface of the first supporting surface 31 intersects with the extending surface of the second supporting surface 41, which means that the screen is in a folded state, and the supporting member 4 is folded left to avoid the corresponding space for the screen, so that the supporting member 4 and the screen are prevented from being interfered relatively, and the normal folding function of the terminal device is ensured.

Thus, the first position refers to a state in which the support 4 is lifted up and supports the screen, and the second position refers to a state in which the support 4 is retracted and retreats from the screen.

For example, the direction of rotation of the first rotating member 2 relative to the base 1 coincides with the direction of rotation of the supporting member 4 relative to the connecting member 3, and it is to be understood that, during the transition of the supporting member 4 from the first position to the second position, as shown in fig. 2 and 3, the first rotating member 2 is deflected counterclockwise relative to the base 1, and the supporting member 4 is deflected counterclockwise relative to the connecting member 3.

Specifically, as shown in fig. 1 and 2, the left end of the first rotating member 2 is rotatably connected with the base 1, the connecting member 3 is rotatably connected with the right end of the first rotating member 2, the first supporting surface 31 is the upper surface of the connecting member 3, the second supporting surface 41 is the upper surface of the supporting member 4, and the right end of the supporting member 4 is rotatably connected with the connecting member 3. When the rotating shaft assembly is changed from the first position (supporting state) to the second position (folding state) (namely, the state of fig. 2 is changed into the state of fig. 3), the base 1 is not moved, the first rotating member 2 deflects anticlockwise relative to the base 1, and the first rotating member 2 drives the connecting member 3 to deflect anticlockwise, so that the supporting member 4 is driven to deflect anticlockwise relative to the connecting member 3.

According to the rotating shaft assembly, the supporting piece 4 is arranged at the folding position of the screen, so that the phenomenon that the folding position of the screen is sunken in a flattened state is avoided, the normal folding function of terminal equipment is guaranteed, an avoidance space is provided for the screen, the screen at the folding position and the supporting piece 4 cannot interfere in the folding process of the screen, the folding feasibility of the screen is improved, the rotating shaft assembly is simple and compact in structure, the space occupation rate is low, the screen is well adapted to change, and the screen cannot be pulled and extruded.

When the first rotating member 2 deflects anticlockwise relative to the base 1, the second rotating member 5 also deflects anticlockwise relative to the base 1, and meanwhile, the second rotating member 5 and the connecting member 3 slide relatively, so that the supporting member 4 deflects anticlockwise relative to the connecting member 3, and the folding of the rotating shaft assembly is achieved.

When the support member 4 is at the second position, as shown in fig. 3, the first engaging portion 33 and the third engaging portion 51 are separated from each other, and when the first rotating member 2 deflects clockwise, the second rotating member 5 and the connecting member 3 slide relatively, and the third engaging portion 51 on the second rotating member 5 gradually approaches the first engaging portion 33 and engages with the first engaging portion 33, so as to drive the first engaging portion 33 to rotate, and the first engaging portion 33 rotates and drives the support member 4 to deflect outwards to lift, so that the support member 4 deflects from the second position to the first position, and the screen is supported by lifting the support member 4.
