The cover plate 20 includes an open state and a closed state, and the stand 10, the link frame 30, the support member 40, and the link member 50 are located at an inner side of the cover plate 20 when the cover plate 20 is in the closed state. The cover 20 has a connecting portion 21 at one end, and the connecting portion 21 is rotatably connected to an external device such as a main body through a hinge or the like, so that the cover 20 can be rotated between an open state and a closed state.

It is understood that the cover plate 20 may be integrally formed or assembled from several parts.

The stand 10 is fixed to an external device such as a main body, and the stand 10 is rotatably coupled to one end of the support 40 and serves to support the support 40 when the cover is in the open state.

The connecting frame 30 is fixed to the cover plate 20 and is provided with a slide groove 31, and the slide groove 31 is used for sliding fit with the supporting member 40.

As shown in fig. 3, in some embodiments, the connecting frame 30 includes a fixing plate 32 and a bending plate 33, the fixing plate 32 is fixed to the inner side of the cover plate 20 by bolts, rivets, or welding, the bending plate 33 extends from one side of the fixing plate 32 to a direction away from the cover plate 20, such that the connecting frame 30 is substantially L-shaped, and the sliding grooves 31 are formed on the bending plate 33 and penetrate through opposite sides of the bending plate 33. By arranging the connecting frame 30 in an L shape, the chute 31 can be conveniently arranged as a through groove, and the connecting strength between the connecting frame 30 and the cover plate 20 can be ensured.

In other embodiments, the connecting frame 30 and the cover plate 20 may also be integrally formed, that is, the connecting frame 30 is a part of the cover plate 20, and the shape of the connecting frame 30 is not limited to an L-shape, such as a block shape, etc. is also possible.

The supporting member 40 includes a fixed end 41 and a movable end 42, the fixed end 41 is rotatably connected to the bracket 10, and the movable end 42 is fixed with a connecting member 50 and slidably connected to the sliding groove 31 through the connecting member 50, so that the cover plate 20 can rotate relative to the bracket 10.

The fixed end 41 and the movable end 42 are disposed at an angle, so that the supporting member 40 is formed in a V-shape. In other embodiments, the fixed end 41 and the movable end 42 may be assembled separately, and the supporting member 40 may also be U-shaped or arched.

Referring to fig. 3 and 4, the sliding slot 31 includes a sliding section 311 and a limiting section communicated with the sliding section 311, the limiting section includes a first limiting section 312 and a second limiting section 313, and the first limiting section 312 and the second limiting section 313 are respectively located at two ends of the sliding section 311 and are communicated with the sliding section 311.

When the connecting element 50 on the supporting element 40 moves to the first position-limiting section 312, the connecting element 50 and the first position-limiting section 312 cooperate to limit the rotation of the cover plate 20, so that the supporting element 40 maintains an upright state to support the cover plate 20, and the cover plate 20 maintains an open state, and at this time, the first position-limiting section 312 is located below the second position-limiting section 313 and closer to the stand 10. When the connecting element 50 on the supporting element 40 moves into the second position-limiting section 313, the connecting element 50 and the second position-limiting section 313 cooperate with each other to limit the inward rotation of the cover plate 20, so that the supporting element 40 is kept in a horizontal state to be received under the cover plate 20, and the cover plate 20 is kept in a closed state. When the connecting member 50 on the support 40 slides within the sliding section 311, the cover 20 rotates between the open state and the closed state.
