Therefore, the first rotating arm 601 is adapted to be fitted within the first limit groove 801 so that the position of the first rotating arm 601 is limited, and the second rotating arm 602 is adapted to be fitted within the second position limit groove 802 so that the position of the second rotating arm 602 is limited.

Particularly, the first rotating rod 6011 is cooperated with the first position limit grooves 801 and moves along the vertical first position limit grooves 801 until the first rotating rod 6011 reaches the bottom of the first position limit grooves 801 , thus limiting the position of the first rotating rod 6011. Furthermore, the first position limit block 811 may increase the contact area between the first rotating rod 6011 and the position limit structure 8 when the first rotating rod 6011 is moved to the bottom of the first position limit grooves 801, thus enhancing stability of the position limiting.

Similarly, the third rotating rod 6021 is cooperated with the second position limit groove 802 and moves along the vertical second position limit groove 802 until the third rotating rod 6021 reaches the bottom of the second position limit groove 802, thus limiting the position of the third rotating rod 6021. Furthermore, the second limit block 812 may increase the contact area between the third rotating rod 6021 and the position limit structure 8 when the third rotating rod 6021 is moved to the bottom of the second position limit groove 802, thus enhancing stability of position limiting.

The operation of the lifting device according to embodiments of the present disclosure will be described in detail with reference to Figs.1-4.

When it is desired to use and extend the vehicle-mounted equipment out of the dashboard through the opening, the lifting-box assembly 3 is moved upwardly in the vertical direction from the retracted position, via the engagement between the power mechanism 302 disposed in the lifting-box body 301 and the toothed bar 2.

Accordingly, the cover-flipping mechanism 6 is driven to pivot and thus the cover plate 7 is overturned. Finally, the opening of the dashboard 10 is totally opened and the lifting-box assembly 3 reaches the extended position. That is, the cover plate 7 opens the opening and the vehicle-mounted equipment is extended out of the dashboard 10 through the opening.

When the vehicle-mounted equipment is not needed to use and it is desired to retract the vehicle-mounted equipment into the dashboard 10 through the opening, the lifting-box assembly 3 moves downwardly in the vertical direction, via the engagement between the power mechanism 302 in the lifting-box body 301 and the toothed bar 2. Simultaneously, the first and second sliding columns 111, 112 disposed on two sides of the cover- flipping mechanism 6 slide firstly and downwardly in the first vertical groove portion 4012 and the second vertical groove portion 4022 respectively without driving the cover-flipping mechanism 6 to pivot. Secondly, the first and second sliding columns 111, 112 slide leftward in the first horizontal groove portion 4011 and the second horizontal groove portion 4021 respectively with driving the cover-flipping mechanism 6 to pivot. Finally, the lifting-box assembly 3 arrives the retracted position and the opening of the dashboard 10 is totally closed. Therefore, the opening of the dashboard 10 is opened or closed according to the ascending and descending of the lifting-box assembly 3. Accordingly, the opening of the dashboard 10 is closed after the vehicle-mounted equipment being retracted into the dashboard 10, thus ensuring the appearance integrality of the dashboard 10.
