[0030] Referring to the accompanying drawings, the auxiliary support hinge provided by the utility model includes a fixed frame 100, a rotating frame 200, and a connecting rod mechanism, wherein the connecting rod mechanism includes a first connecting rod and a second connecting rod, and the two ends of the first connecting rod and the second connecting rod are respectively connected to the fixed frame 100 and the rotating frame 200, and the first connecting rod and the second connecting rod are rotatably connected to form five axes in the connecting rod mechanism:

[0031] The first axis L1 is a fixed axis relative to the fixed bracket 100 and is an axis of rotational connection between the first end of the first connecting rod and the fixed bracket 100. The first axis L1 is an axis of the first shaft 11;

[0032] The second axis L2 is a displaceable axis, which is a live connection axis between the first end of the second connecting rod and the fixed bracket, so that the second connecting rod can rotate and slide relative to the fixed bracket 100, and the second axis is the axis of the second shaft 12;

[0033] The third axis L3 is a displaceable axis and is the axis of the rotational connection between the first connecting rod and the second connecting rod, and the second axis is the axis of the third shaft 13;

[0034] The fourth axis L4 is a displaceable axis, which is the axis of the movable connection between the second end of the first connecting rod and the rotating bracket 200, so that the rotating bracket 200 can rotate and slide relative to the first connecting rod. The fourth axis is the axis of the fourth shaft 14;

[0035] The fifth axis L5 is a fixed axis relative to the rotating bracket 200 and is an axis of the rotation connection between the second end of the second connecting rod and the rotating bracket 200, wherein the fifth axis is the axis of the fifth shaft 15;

[0036] The third axis L3 is located between the first axis L1 and the fourth axis L4 and between the second axis L2 and the fifth axis L5. When the auxiliary support hinge is in the corresponding support retracted state, the first axis L1 is on the outside of the hinge compared to the second axis L2, and the fifth axis L5 is on the outside of the hinge compared to the fourth axis L4.

[0037] The second shaft 12 is connected to the second connecting rod, the fixed bracket 100 is provided with a fixed bracket long hole 101, and the second shaft 12 is movably connected to the fixed bracket long hole 101; the fourth shaft 14 is connected to the second connecting rod, the rotating bracket 200 is provided with a rotating bracket long hole 201, and the fourth shaft 14 is movably connected to the rotating bracket long hole 201.

[0038] The third axis is located outside the rotating bracket 100 and the fixed bracket 200 and between the rotating bracket 100 and the fixed bracket 200 .

[0039] Due to the adoption of the scheme of the utility model, the following preferred implementations can be selected: the first connecting rod is composed of multiple first sheet components 21, the second connecting rod is composed of multiple second sheet components 22, the first sheet components 21 and the second sheet components 22 are overlapped at intervals. The multiple first sheet components 21 are connected by the first shaft 11 and the third shaft 13 and the fourth shaft 14, and the multiple second sheet components 22 are connected by the second shaft 12 and the third shaft 13 and the fifth shaft 15.

[0040] The auxiliary support hinge is also provided with a rotation damping structure, which is arranged on the third shaft 13. The first sheet component 21 and the second sheet component 22 are both rotationally connected to the third shaft 13. The rotation damping structure includes an elastic element 31 (which can be a plurality of disc springs) sleeved on the third shaft 13. The first sheet component 21 and the second sheet component 22 are pressed together by the elastic element 31 to generate rotation damping. The reference numeral 32 is a nut threadedly connected to the third shaft 13 to press the elastic element 31.

[0041] The fixed bracket 100 is fixedly connected to the supported object 300, the rotating bracket is fixedly connected to the connecting part (such as the legs 500) of the appearance part 400, and the appearance part 400 can be a bendable and restorable elastic plate. The reference numeral 600 is the rear decorative plate of the supported object.

[0042] In the present invention, while the entire assembly rotates around the first axis L1, the sliding of the second connecting rod in the fixed bracket 100 and the sliding of the first connecting rod in the rotating bracket 200 are increased, so that the rotating bracket 200 accelerates the rotation when it is lifted; Figure 5 , 6 As shown, the rotating bracket 200 has rotated 90 degrees, but the rotation angle of the second connecting rod around the first axis L1 is only 32 degrees. In this way, the rotating bracket will swing to the supporting angle in advance, while the first connecting rod will only rotate at a small angle. As a result, when the rotating bracket rotates to the supporting angle, its position deviates further from the first axis, and the compression amount of the appearance part 400 will be reduced.
