Preferably, the first magnetic body 31 may be a permanent magnet, and the second magnetic body 32 may be a soft magnet.

As another specific embodiment of the hinge rotation sequence control mechanism, the suction mechanism may also be a vacuum suction mechanism, for example, a vacuum suction cup is disposed on both the inner surface of the first pair of hinge blades 21 and the inner surface of the second pair of hinge blades 22, or a vacuum suction cup is disposed on the inner surface of the first pair of hinge blades 21 or the inner surface of the second pair of hinge blades 22, so that the first pair of hinge blades 21 and the second pair of hinge blades 22 do not rotate relative to each other during the rotation of the dark hinge, thereby achieving the purpose of controlling the hinge rotation sequence. Alternatively, the suction mechanism may be configured to perform a suction action between the first sub hinge blade 21 and the second sub hinge blade 22.

Referring to fig. 1, as a specific embodiment of the return mechanism, the return mechanism includes a return elastic element 41 and a return pulling element 42, the return elastic element 41 is installed on the outer side surface of the second sub hinge leaf 22, one end of the return pulling element 42 is connected to the first sub hinge leaf 21, and the other end of the return pulling element 42 is connected to the return elastic element 41. During the rotation of the shield door 6 to the fully open position with the first pair of hinge leaves 21, the first pair of hinge leaves 21 applies a pulling force to the return elastic member 41 through the return pulling member 42, so that the return elastic member 41 is in a compressed state. When the shield door 6 needs to be closed, the shield door 6 is pushed, under the action of the return elastic element 41, the first pair of hinge blades 21 are pulled to the position of the second pair of hinge blades 22 by the return pulling element 42 until the first pair of hinge blades 21 and the second pair of hinge blades 22 are attached to each other, the first pair of hinge blades 21 and the second pair of hinge blades 22 are fixedly attached to each other under the action of the adsorption mechanism, then the shield door 6 is continuously pushed, so that the shield door 6 and the auxiliary hinge rotate together along with the hidden hinge until the shield door 6 is closed on the shield 5.

Specifically, the return elastic element 41 may be a return spring, and the return traction element 42 may be a pull rope, such as a steel wire pull rope. Alternatively, the return elastic element 41 may also be other structures with elastic restoring force, such as a rubber sleeve, a silicone sleeve, and the like.

Referring to fig. 1 and 2, the hidden hinge includes a first hidden hinge fan blade 11 and a second hidden hinge fan blade 12, one end of the first hidden hinge fan blade 11 is connected with the inner side surface of the shield 5, the other end of the first hidden hinge fan blade 11 is hinged to the second hidden hinge fan blade 12 through a hidden hinge central axis a, the auxiliary hinge includes a first auxiliary hinge fan blade 21 and a second auxiliary hinge fan blade 22, the second hidden hinge fan blade 12 is connected to the second auxiliary hinge fan blade 22, the second auxiliary hinge fan blade 22 is hinged to the first auxiliary hinge fan blade 21 through an auxiliary hinge central axis B, and the first auxiliary hinge fan blade 21 is connected to the inner side surface of the shield door 6. A return elastic element 41 is installed at one end of the second hidden hinge blade 12 attached to the second auxiliary hinge blade 22, a first magnetic element 31 is installed on the inner side surface of the first auxiliary hinge blade 21, a second magnetic element 32 is installed on the inner side surface of the second auxiliary hinge blade 22, and one end of a return traction element 42 penetrates through the second hidden hinge blade 12 and the second auxiliary hinge blade 22 to be connected with the first auxiliary hinge blade 21.

When the shield door 6 is opened, the shield door 6 is pulled outwards, under the action of the first magnetic body 31 and the second magnetic body 32, the first auxiliary hinge fan blade 21 and the second auxiliary hinge fan blade 22 are attached together at this time, so that the auxiliary hinges can keep a stable state and cannot rotate within a certain stress range, the shield door 6 and the auxiliary hinges rotate to the limit position along with the hidden hinges around the central axis A of the hidden hinges, at this time, the hidden hinges cannot rotate continuously due to the limitation of the sealing strip mounting plate, the shield door 6 is lifted upwards continuously, the shield door 6 overcomes the magnetic force and the spring pressing force between the auxiliary hinges, the auxiliary hinge central axis B continues to rotate by taking the central axis B of the auxiliary hinges as the rotation center, and the shield door 6 reaches the full opening position, so that the opening angle can reach 180 degrees or more; in the process, the return pulling element 42 moves with the first set of hinge leaves 21, putting the return elastic element 41 in compression.

When the shield door 6 is closed, the shield door 6 is pushed downward, under the action of the return elastic element 41, the return traction element 42 pulls the first pair of hinge blades 21 to rotate towards the second pair of hinge blades 22 with the pair of hinge central axes B as the rotation center until the first pair of hinge blades 21 and the second pair of hinge blades 22 are attached, the shield door 6 is continuously pushed downward, and the hidden hinge rotates around the hidden hinge central axis a until the shield door 6 is closed.

By adopting the mode of combining the hidden hinge and the auxiliary hinge, the hidden hinge and the auxiliary hinge can rotate around respective rotating shafts respectively, so that the shield door has a larger opening angle.

The structures such as magnets and return springs are installed between the auxiliary hinges, the auxiliary hinges are enabled to be integrated in a certain stress range and free rotation cannot occur, meanwhile, opening force between the auxiliary hinges cannot be large, opening process is too laborious, and the rotation sequence of the hidden hinges and the double shafts of the auxiliary hinges can be controlled. The auxiliary hinge is also provided with a return mechanism which is used for controlling the auxiliary hinge to return
