As shown in fig. 18-19, at this time, the first cover body 2 rotates to form an included angle of 90 degrees with the supporting seat, and the second cover body 3 rotates to form an included angle of 120 degrees with the supporting seat.

As can be seen, in the present embodiment, the angular velocity of the first cover 2 is 0.75 times the angular velocity of the second cover 3.

In this embodiment, the supporting device may not be provided with the self-locking device and the unlocking device, the first cover 2 and the second cover 3 may rotate to overlap, and the supporting device may also be provided with the self-locking device and the transmission manner between the sun gear 513 and the first pivot member 21. When the second cover 3 rotates to the preset angle, the second cover 3 stops rotating, and the first cover 2 can continue to rotate, in this embodiment, the preset angle is 130 degrees.

When the first cover body 2 is to be re-closed, the first cover body 2 may be first closed to the closed state, then the user releases the locking of the self-locking device from the second cover body 3 by hand, and then rotates the second cover body 3 to abut against the supporting seat by hand. Because the first cover 2 is already in the closed state, when the user rotates the second cover 3, the first cover 2 cannot rotate synchronously, and the pivot 5131 of the sun gear 513 slides relative to the second cover 3.

Certainly, a user may also release the self-locking device from the second cover 3 by hand, and then rotate the first cover 2, because a general user will continue to rotate the first cover 2 when the second cover 3 rotates to the preset angle, even if the angular velocity of the first cover 2 is equal to the angular velocity of the second cover 3 when the first cover 2 is to be returned to the closed state, because the rotated angle of the first cover 2 is greater than the rotated angle of the second cover 3, the second cover 3 will first abut against the supporting seat, and at this time, the first cover 2 continues to rotate, and the pivot 5131 of the sun gear 513 and the second cover 3 slide relative to each other until the first cover 2 returns to the closed state.

Of course, the user can release the self-locking device from the second cover 3 by a button mechanism disposed at the hinge, which is not limited to this.

As shown in fig. 18-19, at this time, the first cover body 2 rotates to form an included angle of 120 degrees with the supporting seat, and the second cover body 3 rotates to form an included angle of 130 degrees with the supporting seat.

The flexible connecting portion 26 of the second embodiment can also be used in the third embodiment, when the second cover 3 is limited by the self-locking device to stop rotating, the first cover 2 can rotate in the direction of returning to the closed state, and the cover surface 24 and the pivot surface 25 are relatively turned over, so that the input device is shielded by the axial projection of the portable computer.

Of course, when the self-locking device is not provided or the second cover 3 does not reach the predetermined angle, the cover surface 24 may abut against the pivot surface 25, and the pivot surface 25 returns to the closed state, and the display device of the portable computer faces upward.

In the absence of the self-locking device, the angular velocities of the first cover 2 and the second cover 3 may be configured such that the second cover 3 has rotated through an included angle of 90 degrees when the portable computer is in a use state similar to that shown in fig. 11 or 13.

Referring to fig. 22-24, a fourth embodiment of the present invention is shown, in combination with the third embodiment, in order to make the angular speeds of the rotation of the first cover 2 and the second cover 3 the same, the transmission mechanism 5 includes a first planetary gear set disposed at the hinge, and the transmission mechanism 5 further includes a second planetary gear set drivingly connected with the first planetary gear set through a common sun gear 513. The first planetary gear set includes a first ring gear 521 and a first carrier 522, and the second planetary gear set includes a second ring gear 531 and a second carrier 532.

First lid 2 transmission is connected first ring gear 521 of first planetary gear set, supporting seat 1 rigid coupling first planetary gear of first planetary gear set with second ring gear 531 of second planetary gear set, second lid 3 transmission is connected second planetary gear of second planetary gear set, works as when first lid 2 rotates, drives second lid 3 antiport.

When the first cover 2 rotates, the first gear ring 521 is driven to rotate in the same direction, and the first gear ring 521 drives the sun gear 513 to rotate in the opposite direction. Then, the sun gear 513 is transmitted to the second planetary gear set, and since the second planet carrier 532 is fixed to the support base 1, the rotation direction of the second planet carrier 532 is the same as the rotation direction of the sun gear 513, so that the rotation directions of the first cover 2 and the second cover 3 are opposite.

In the transmission principle of the planetary gear set, when the planet carrier is fixed, the gear ring is driven, and the sun gear is driven, the angular speed of the sun gear is greater than that of the gear ring. When the gear ring is fixed, the sun gear is driven, and the planet carrier is driven, the angular velocity of the planet carrier is smaller than that of the sun gear.

In this embodiment, therefore, the first ring gear 521 is geared such that the angular velocity of the sun gear 513 is greater than the angular velocity of the first ring gear 521, and then to the second planetary gear set, and the sun gear 513 is geared such that the angular velocity of the second carrier 532 is less than the angular velocity of the sun gear 513. That is, the angular velocity of the first cover 2 is accelerated and then decelerated to the second cover 3, so the transmission mechanism 5 may be configured to make the angular velocity of the first cover 2 equal to the angular velocity of the second cover 3, and the rotation directions of the two are opposite.

The structure in the second embodiment may also be combined in this embodiment, and is not limited thereto.

The supporting device is further provided with an elastic assisting element 8 at the hinged part 4, the elastic assisting element 8 is in transmission connection with the supporting seat 1 and the first cover body 2, and the elastic assisting element 8 accumulates elastic force when the first cover body 2 is in a covering state. The first cover 2 can be detachably fixed to the support base 1 by the fixing device described in the first embodiment, when the fixing device is released, the elastic assisting element 8 enables the first cover 2 to rotate in the direction of releasing the covering state, and the elastic assisting element 8 can be further configured to enable the elastic force of the elastic assisting element 8 to be completely released when the first cover 2 reaches a preset turning angle. In this embodiment, the first cover body 2 includes a sleeve abutting column 27 disposed in the circumferential sleeve 41 and capable of rotating around the axis of the circumferential sleeve 41 coaxially, the elastic assisting element 8 is a torsion spring sleeved on the sleeve abutting column 27, one end of the torsion spring is fixedly connected to the sleeve abutting column 27, and the other end of the torsion spring is fixedly connected to the inner peripheral wall of the circumferential sleeve 41 of the support seat 1. When the first cover body 2 is in a covering state, elasticity is accumulated in the torsion spring, and when the first cover body 2 rotates to the preset overturning angle, the torsion spring completely releases elasticity. Of course, the elastic assisting element 8 may also be selected from other elements having a rotation elastic force, and is not limited thereto.

In this embodiment, the fixing device may also be a snap unlocking structure provided on the first cover 2 and the circumferential sleeve 41, and the snap unlocking structure is provided in two and provided at both ends of the circumferential sleeve 41. The fixing device is configured to enable the first cover body 2 to be unlocked in a covering state only when a user releases the two buckle unlocking structures at the same time, so that the risk of misoperation can be reduced for the user.

The elastic force of the elastic force-aid member 8 can be selected by the user only touching the fixing device without using hands, or by adding additional force-aid when the user turns over the first cover 2.
