As shown in fig. 1-3, an embodiment of the present application provides a flip hinge structure, which includes a first hinge portion 1, a second hinge portion 2, a first direction rotating shaft 3 and a second direction rotating shaft 4, wherein the first direction rotating shaft 3 and the second direction rotating shaft 4 are both sleeved with an elastic reset member 5, and the elastic reset member 5 is sleeved in the middle of the first direction rotating shaft 3 and the second direction rotating shaft 4.

The first hinge parts 1 comprise at least two first hinge plates 11, every two adjacent first hinge plates 11 are hinged through a second direction rotating shaft 4, the second hinge parts 2 comprise at least two second hinge plates 21, every two adjacent second hinge plates 21 are hinged through a second direction rotating shaft 4, and every first hinge plate 11 is hinged with every second hinge plate 21 through a first direction rotating shaft 3.

Specifically, the axial direction of the first-direction rotating shaft 3 is perpendicular to the axial direction of the second-direction rotating shaft 4. In this embodiment, when the axis of the second direction rotating shaft is perpendicular to the axis of the first direction rotating shaft, so that the second hinge plate and the first hinge plate rotate relatively, the elastic reset pieces 5 arranged on the second direction rotating shaft at two sides of the axis of the first direction rotating shaft generate elastic acting force towards the first direction rotating shaft. Specifically, when the first hinge part 1 is fixed and the second hinge part 2 rotates towards the direction close to the first hinge part 1, the second hinge part 2 is folded in parallel relative to the first hinge part 1 under the action of the elastic reset piece 5 on the second direction rotating shaft 4; when the first hinge portion 1 is fixed and the second hinge portion 2 rotates in a direction away from the first hinge portion 1, the second hinge portion 2 is vertically folded relative to the first hinge portion 1 under the action of the elastic reset member 5 on the second direction rotating shaft 4.

Specifically, each first hinge plate 11 or second hinge plate 21 and the side of the other first hinge plate 11 or second hinge plate 21 adjacent thereto, which is hinged to the hinge plate, are provided with mounting holes 6, and the first direction rotating shaft 3 and the second direction rotating shaft 4 are in fit connection with the mounting holes 6.

It should be noted that, in this embodiment, the flip hinge structure includes two first hinge plates 11, two second hinge plates 21, two first direction rotating shafts 3 and two second direction rotating shafts 4, where the two first hinge plates 11 are hinged through one second direction rotating shaft 4, the two second hinge plates 21 are hinged through the other second direction rotating shaft 4, and the first hinge plates 11 and the second hinge plates 21 are hinged through the first direction rotating shafts 3.

In this embodiment, when the second hinge portion 2 rotates relative to the first hinge portion 1, the elastic restoring members 5 on the two second direction rotating shafts 4 located at two sides of the rotation axis and perpendicular to the rotation axis generate an elastic acting force perpendicular to the rotation axis, which enables the two hinge portions to have a certain buffering during the rotation process, and the second hinge portion 2 can maintain a right-angled position perpendicular to the first hinge portion 1 after being folded and unfolded, and a certain force is required to close the second hinge portion during folding and retracting, for example, a force of 15N to 25N is required to fold the second hinge portion from the folded and retracted position in some embodiments.

The present embodiment flip hinge structure may be applied to folding and hinge of doors and windows, desktops, wardrobe doors, cabinet doors, seats, etc., and includes but is not limited to the above-described structure.

The embodiment also provides a seat widening armrest, as shown in fig. 4 and 5, which comprises an armrest main body 7, an armrest widening plate 8 and at least one flip hinge structure 10, wherein the first hinge part 1 of the flip hinge structure 10 is fixedly connected with the armrest main body 7, and the second hinge part 2 is fixedly connected with the armrest widening plate 8.

Specifically, the armrest body 7 includes a body frame 71, a body foam 72, and a body cover 73, and the body cover 73 is used to wrap the body foam 72 on the body frame 71. The outer side surface of the handrail main body 7 is provided with a receiving groove 74 which is matched with the handrail widening plate 8.

Specifically, the handrail widening board 8 includes a widening board frame 81, a widening board foam 82, and a widening board cover 83, and the widening board foam 82 is completely coated on the outer surface of the widening board frame 81 by the widening board cover 83. The width of the handrail widening plate 8 is not greater than the width of the side face of the handrail main body 7. That is, the width of the handrail widening plate 8 depends on the width of the side surface of the handrail main body 7, so that the handrail widening plate 8 does not exceed the handrail main body 7 after being folded, so as not to interfere with and occupy an excessive space.

In the present embodiment, the armrest widening plate 8 is hinged to the armrest body 7 by two flip hinge structures 10, and the armrest widening plate 8 can rotate relative to the armrest body 7. Specifically, the armrest body 7 may be fixedly connected to the first hinge portion 1 by a fastener 9, and the armrest widening plate 8 may be fixedly connected to the second hinge portion 2 by a fastener. The handrail widening plate 8 is hinged to the upper edge of the outer side face of the handrail main body 7, and the handrail widening plate 8 is parallel to the upper surface of the handrail main body 7 after being unfolded, so that the supporting surface of the handrail main body 7 can be widened, and the arms of passengers can be better supported and relaxed. When the armrest widening plate 8 is retracted, the armrest widening plate 8 is retracted into the accommodating groove 74 on the side surface of the armrest body 7, and space on both sides of the seat is not occupied.

This application is articulated with handrail widening board and handrail main part through upset hinge structure, can widen the seat armrest and increase, and the bigger degree satisfies passenger's arm and takes advantage of the pressure scope, better provides passenger's travelling comfort, and simple structure is with low costs simultaneously, and the realization cycle is short, the simple operation, and the practicality is strong.

The present embodiment also provides an automobile seat, as shown in fig. 6, including a seat main body 9 and the seat widening armrest described above.

In the case of a car with a limited space in the car, armrests on both sides of the seat are usually designed to be narrow in order to save the space in the car when the space for arranging the seat is narrow. This application seat main part is installed the seat and is widened the handrail, and the seat is widened the handrail and is had the handrail and widen the board, and the passenger can expand the width that increases the handrail with the handrail widening board when taking the seat, support arm that can be better, alleviate arm fatigue, improve the travelling comfort. In some cases, small articles can be placed through widening the handrail plate, and the handrail plate is convenient to take during driving. Because the hinged turnover hinge structure 10 has a simple structure, the armrest widening plate can be directly used by being turned over when needed, and the armrest widening plate does not occupy the seat space and is convenient to use.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
