[0027] Each of the first substrate 3 and the second substrate 4 has at least one inwardly extending rib 7 on its inner surface, and the two ribs 7 facing each other are connected by overlapping.

[0028] Example 2: A portable tablet computer includes: a tablet computer body 100, and a support 200 rotatably mounted on one side of the tablet computer body 100 via at least two spaced-apart pivot assemblies 300, such that when the pivot assembly 300 rotates to a 0° position, the support 200 is parallel and in contact with the tablet computer body 100. The pivot assembly 300 includes: a base 1 fixedly mounted on the tablet computer body 100 and a slider 2 connected at one end to the support 200. The base 1 includes a first substrate 3 and a second substrate 4 that are parallel and spaced apart from each other. The outer side of the slider 2, which is disposed between the first substrate 3 and the second substrate 4, slides with the inner surface of the first substrate 3 and the second substrate 4 through a set of arc-shaped grooves 51 and arc-shaped protrusions 52.

[0029] On the inner surface of each of the first substrate 3 and the second substrate 4, and on the side of the slider 2 opposite to the support 200, there is a strip-shaped guide groove 81 extending along its length. Both ends of a sliding pin 82 are slidably embedded in the strip-shaped guide groove 81. A torque pin 9 is installed at the other end of the slider 2 away from the support 200. Between the torque pin 9 and the sliding pin 82, which are tightly connected at both ends to the slider 2, there are several torque plates 10 arranged sequentially along the axial direction of the torque pin 9 and the sliding pin 82. One end of the torque plate 10 is fitted onto the outside of the torque pin 9 and is press-fitted with the torque pin 9. A first magnetic block 16 is embedded at the end of the slider 2 away from the torque pin 9. A second magnetic block 17 that cooperates with the first magnetic block 16 is provided on the tablet computer body 100.

[0030] The inner surfaces of the first substrate 3 and the second substrate 4 are each provided with at least one inwardly extending rib 7, and two ribs 7 facing each other are welded together; one end of the strip guide groove 81 is provided close to the arc groove 51 or the arc protrusion 52, and the other end of the strip guide groove 81 extends away from the arc groove 51 or the arc protrusion 52.

[0031] The bracket 200 is a metal bracket; one end of the bracket 200 is connected to the slider 2 through a set of connecting grooves 61 and connecting protrusions 62, the connecting protrusions 62 are embedded in the connecting grooves 61 and fixedly connected by screws; the other end of the bracket 200 is used to make contact with the supporting plane.

[0032] When assembling the shaft assembly:

[0034] Next, press one end of the torque plate into the torque pin mounted on the slider, and at the same time assemble the other end of the torque plate into the sliding pin.

[0035] Next, the slider is screwed in and the sliding pin is installed into the base. At this time, the first substrate and the second substrate of the base are in an independent state.

[0036] Finally, the base is connected as a whole by screwing and welding the ribs on the first and second substrates together.

[0037] The assembled hinge assembly is inserted into the mounting slot of the tablet body, and then the slider of the hinge assembly is connected to the bracket. The bracket drives the slider of the hinge assembly to rotate so that the bracket can be opened to support the tablet body or closed to fit the tablet body.

[0038] When the stand and the slider that rotates with the stand are at the 0° position, the first magnetic block on the slider is attracted to the second magnetic block in the mounting groove, thereby ensuring a complete fit between the stand and the tablet body without warping.

[0039] As the stand and the slider that rotates with the stand rotate from 0° to a certain angle to support the tablet body, the torque pin that is interference-fitted with the torque plate rotates within the holding area of ​​the torque plate to generate torque, thereby providing stable support for the stand at any angle.

[0040] When using the aforementioned portable tablet computer, the built-in stand allows for rotational switching in different usage scenarios, improving the ease of use of the tablet computer. Furthermore, through the cooperation between the torque plate and the torque pin, stable torque can be provided during the support process of the stand being rotated out to ensure the stability of the stand's support function during repeated use. It can also improve the stability of the stand in the closed state, avoiding the "smiling" problem and enhancing the user experience.
