Referring to fig. 1-2, a preferred embodiment of the present invention is provided, which has the following specific schemes:

an articulated structure comprising

The first fixing seat 1 is hinged to one end of a first hinged shaft C1 and one end of a third hinged shaft C3, and the second fixing seat 2 is hinged to one end of a second hinged shaft C2 and one end of a fourth hinged shaft C4;

in this embodiment, as shown in fig. 1, the first fixing seat 1 includes a first fixing platform 11, a first hinge seat 12 and a third hinge seat 13 are fixedly extended from the same side of the first fixing platform 11, the first hinge seat 12 is hinged to one end of a first hinge shaft C1, and the third hinge seat 13 is hinged to one end of a third hinge shaft C3; and the extension size of the first hinge base 12 is larger than the extension size of the third hinge base 13.

In this embodiment, as shown in fig. 1, the second fixing seat 2 includes a second fixing platform 21, a second hinge seat 22 and a fourth hinge seat 23 are fixedly extended from the same side of the second fixing platform 21, the second hinge seat 22 is hinged to one end of a second hinge shaft C2, and the fourth hinge seat 23 is hinged to one end of a fourth hinge shaft C4; and the extension dimension of the second hinge base 22 is greater than the extension dimension of the fourth hinge base 23. The purpose of this arrangement is that, when the access door is closed, the hinge structure is as shown in fig. 1, at this time, a space is provided between the relatively arranged third hinge seat 13 and the fourth hinge seat 23 with a smaller extension size for accommodating the first fork arm 3, the second fork arm 4 and the seventh hinge shaft C7, and the relatively arranged first hinge seat 12 and the second hinge seat 22 with a larger extension size are relatively close to or even abut against each other, so that the hinge structure can realize a self-limiting effect when the access door is closed.

As a further preferred feature of this embodiment, the first hinge seat 12 and the third hinge seat 13 are diagonally disposed on the same side of the first fixed platform 11, the second hinge seat 22 and the fourth hinge seat 23 are diagonally disposed on the same side of the second fixed platform 21, and in the front-rear direction, the first hinge seat 12 corresponds to the fourth hinge seat 23, and the second hinge seat 22 corresponds to the third hinge seat 13 in position, so that while saving the internal structure, the opening and closing support of each hinge structure in the front-rear direction can be realized by the combination of 2 sets of hinge seats, fork arms and straight arms, and when one set of hinge seat fails, the normal use of the other set of hinge seat cannot be affected.

As shown in fig. 1, in the present embodiment, a first mounting hole 111 is formed in the first fixing platform 11, and a second mounting hole 211 is formed in the second fixing platform 21; can realize first fixed platform, second fixed platform and access door A and car shell B's fixed mounting through first mounting hole and second mounting hole, in this embodiment, first fixed platform 11 is through first mounting hole 111 and access door A fixed connection, and second fixed platform 21 is through second mounting hole 211 and car shell B fixed connection to realize opening and close of access door A for car shell B through this hinge structure.

As shown in FIG. 1, the present embodiment further comprises

A first straight arm 5 and a second straight arm 6, wherein one end of the first straight arm 5 is hinged with the other end of the third hinge shaft C3, and one end of the second straight arm 6 is hinged with the other end of the fourth hinge shaft C4; and

the device comprises a first fork arm 3 and a second fork arm 4, wherein one end of the first fork arm 3 is hinged with the other end of a first straight arm 5, and the other end of the first fork arm 3 is hinged with the other end of a second hinged shaft C2; one end of the second forked arm 4 is hinged with the other end of the second straight arm 6, and the other end of the second forked arm 4 is hinged with the other end of the first hinged shaft C1;

the middle parts of the first fork arm 3 and the second fork arm 4 are respectively hinged with two ends of a seventh hinge shaft C7.

Preferably, in the front-rear direction, the first fork arm 3 and the first straight arm 5 are located at the front side of the second fork arm 4 and the second straight arm 6, so that internal structures are saved, and meanwhile, the opening and closing support of each hinge structure in the front-rear direction can be realized by the combination of 2 groups of hinge seats, fork arms and straight arms, and the normal use of one group cannot be influenced when the other group is damaged and failed.

As a further preferable feature of this embodiment, the first yoke 3 and the second yoke 4 are arc-shaped arms, a hinge point between a middle portion of the first yoke 3 and the seventh hinge shaft C7 is located outside a connection line between a hinge point between the first yoke 3 and the first straight arm 5 and a hinge point between the first yoke 3 and the second hinge shaft C2, and a hinge point between a middle portion of the second yoke 4 and the seventh hinge shaft C7 is located outside a connection line between a hinge point between the second yoke 4 and the second straight arm 6 and a hinge point between the second yoke 4 and the first hinge shaft C1, so that when the access door is opened, as shown in fig. 2, the first yoke and the second yoke are arched, so that after the access door a rotates 180 degrees relative to the car shell B when the access door a is opened, an accommodating space between the access door a and the car shell B at bottoms of the second yoke 4 and the second straight arm 6 in fig. 2 is further increased.

During specific use, as shown in fig. 3, at this time, the access door a is in a closed state relative to the car shell B, the hinge structure is in a state shown in fig. 1, when the access door a is opened relative to the car shell B, the access door a drives the first fixing seat 1 fixedly connected with the access door a to rotate around the second hinge shaft C2 and the fourth hinge shaft C4 integrally and clockwise, and simultaneously drives the first straight arm 5 and the second straight arm 6 to rotate around the corresponding hinge shafts until the access door a rotates to a position shown in fig. 2, at this time, the access door a and the car shell B are both located at the bottoms of the first fork arm 3 and the second fork arm 4 in fig. 2, and the hinge structure is blocked and cannot rotate any more, so that a limiting function of the access door a in an opened state is realized, at this time, the access door a is in an opened state relative to the car shell B, as shown in fig. 4.

In this embodiment, the mode of articulated seat, yoke, straight arm overcoat in corresponding articulated shaft is all selected for use to the articulated mode, and as preferred, each articulated shaft is riveted with articulated seat, yoke, straight arm of corresponding.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
