In this scenario, the conventional single-friction roll-round form or the Kick stand form with a virtual rotating shaft will cause serious wrinkling of the appearance part at the opening turning point when the hinge is opened. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a snap-type auxiliary support hinge, which can provide auxiliary support at the back, and at the same time, can reduce the amount of wrinkles of the appearance part on its outer side when opened, and can achieve an elastic driving snap feel with energy storage in the first stage and energy release in the second stage both when opened and closed. For this purpose, the utility model adopts the following technical solutions

[0004] The snap-type auxiliary support hinge is characterized in that it includes a link mechanism, and the link mechanism includes a first fixed link, a second rotating link, a third rotating link and a fourth rotating link.

[0005] The fourth rotating link is provided with a connecting part and can be connected to the support leg;

[0006] Taking the axis of rotation connection between the second rotating link and the first fixed link as the first axis, the axis of rotation connection between the fourth rotating link and the second rotating link as the second axis, the axis of rotation connection between the third rotating link and the first fixed link as the third axis, and the axis of rotation connection between the fourth rotating link and the third rotating link as the fourth axis. When the hinge is in the first state corresponding to the retraction of the support leg and the second state corresponding to the support leg being opened to the maximum angle, the second axis is respectively located on both sides of the plane determined by the first axis and the fourth axis; and, the snap-type auxiliary support hinge is also provided with a torsion spring. When changing from the first state to the second state, the torsion spring is first compressed for energy storage and then releases energy, and when changing from the second state to the first state, the torsion spring is first compressed for energy storage and then releases energy.

[0007] On the basis of adopting the above technical solutions, the utility model can also adopt the following further technical solutions, or use a combination of these further technical solutions:

[0008] The torsion spring is sleeved on the connecting shaft of the third rotating link and the first fixed link, one end of the spring arm is connected to the connecting shaft of the fourth rotating link and the second rotating link, and the other end of the spring arm is connected to the connecting shaft of the fourth rotating link and the third rotating link.

[0009] The length of the second rotating link is smaller than that of the third rotating link, and the length of the third rotating link is smaller than that of the first fixed link. In the first state, the angle between the third rotating link and the first fixed link is smaller than the angle between the second rotating link and the first fixed link.

[0010] The first fixed link is combined in the fixing frame of the auxiliary support hinge and is a part of the fixing frame. The fourth rotating link extends in a direction away from the second rotating link, and the connecting portion is arranged at the extending portion.

[0012] The first fixed link is provided with a mounting groove with an opening facing the third rotating link, and the connecting shaft of the third rotating link and the first fixed link is put into the mounting groove from the groove, positioned by the mounting groove, and welded to the first fixed link.

[0013] The first fixed link is fixedly connected to the supported object, and the fourth rotating link is fixedly connected to a supporting leg, an appearance part or a connecting part of the appearance part of the supported object.

[0014] The connecting part of the appearance part includes a leg supporting an object; and the appearance part includes an elastic plate that can be bent and restored.

[0015] Due to the technical solution of the utility model, the entire assembly rotates around a fixed rotation point through a connecting rod structure, so that the rotating bracket accelerates its rotation when it is lifted, and the compression amount of the outer appearance parts of the swing arm will be reduced, thereby reducing the amount of wrinkles on the outer appearance parts. There is no need for an external torque mechanism, and only a torsion spring is used to generate a bidirectional force at a small angle to provide a snap-on feel. In addition, the utility model uses a connecting rod method instead of a virtual center of circle solution as an external support hinge, which has a smaller shaking value than the kick stand type.

[0024] Referring to the attached drawings, the snap-type auxiliary support hinge of the present utility model includes a link mechanism. The link mechanism includes a first fixed link 1, a second rotating link 2, a third rotating link 3, and a fourth rotating link 4. The second rotating link 2, the third rotating link 3, and the first fixed link 1 are rotatably connected. The fourth rotating link 4 is rotatably connected to the second rotating link 2 and the third rotating link 3, and:

[0025] The fourth rotating link 4 is provided with a connecting portion 41 and can be connected to the support leg 500;

[0026] Taking the axis of rotation of the second rotating link 2 and the first fixed link 1 as the first axis (the corresponding connecting shaft is the first connecting shaft 10), the axis of rotation of the fourth rotating link 4 and the second rotating link 2 as the second axis (the corresponding connecting shaft is the second connecting shaft 20), the axis of rotation of the third rotating link 3 and the first fixed link 1 as the third axis (the corresponding connecting shaft is the third connecting shaft 30), and the axis of rotation of the fourth rotating link 4 and the third rotating link 3 as the fourth axis (the corresponding connecting shaft is the fourth connecting shaft 40), in the snap-type auxiliary support hinge corresponding to the state where the support leg is retracted (please see Figures 1-3 ) that is, the first state and the state where the support leg is opened to the maximum angle (please see Figure 5When in the second state, that is, the second axis is located on both sides of the plane determined by the first axis and the fourth axis; and, the snap-type auxiliary support hinge is also provided with a torsion spring 5. When changing from the first state to the second state, the torsion spring 4 is first compressed for energy storage and then releases energy. The critical angle of its conversion is that the fourth rotating link rotates to a position where the first axis, the second axis, and the fourth axis are in the same plane. When changing from the first state to the critical angle, the support leg 500 needs to be manually pulled to store energy in the torsion spring. When changing from the critical angle to the second state, the torsion spring releases energy and the support leg 500 is automatically sprung open; when changing from the second state to the first state, it also passes through the critical angle of conversion. When changing from the second state to the critical angle, the support leg 500 needs to be manually pulled, and the torsion spring 4 is compressed for energy storage. When changing from the critical angle to the first state, the torsion spring releases energy and the support leg 500 is automatically driven to close, forming a snap-type feel.

[0027] The torsion spring can be connected in the following way: The torsion spring 5 is sleeved on the connecting shaft (the third connecting shaft 30) of the third rotating link 3 and the first fixed link 1. One end spring arm 51 is connected to the connecting shaft (the first connecting shaft 10) of the fourth rotating link 4 and the second rotating link 2, and the other end spring arm 52 is connected to the connecting shaft (the fourth connecting shaft 40) of the fourth rotating link 4 and the third rotating link 3.

[0028] A preferred implementation is that the length of the second rotating link 2 is less than that of the third rotating link 3, and the length of the third rotating link 3 is less than that of the first fixed link 1. In the first state, the included angle between the third rotating link 3 and the first fixed link 1 is less than the included angle between the second rotating link 2 and the first fixed link 1. In this way, it can be more suitable for reducing the thickness.

[0029] The first fixed link 1 is combined in the fixed frame 100 of the auxiliary support hinge and is a part of the fixed frame 100 (that is, the part of the fixed frame between the first connecting shaft 10 and the third connecting shaft 30). The fourth rotating link 4 extends away from the second rotating link 2, and the connecting part 41 is provided at the extending part.

[0030] A limit cooperation structure is provided on the fourth rotating link 4 and the first fixed link 1, including a protrusion 42 on the fourth rotating link 4 and a gear position 11 on the first fixed link 1, which are used to limit the maximum opening angle of the fourth rotating link 4. For the limit when closing, it can be formed by the cooperation of the support leg and the fixed structure on the notebook computer.

[0031] The first fixed link 1 is provided with an installation groove 12 with an opening facing the third rotating link 3. The connecting shaft (the third connecting shaft 30) of the third rotating link 3 and the first fixed link 1 is placed into the installation groove 12 from the notch of the installation groove 12, and is positioned by the installation groove 12 and welded to the first fixed link 1, making the installation of the third connecting shaft 30 simpler.

[0032] The fixing bracket 100 is fixedly connected to the object to be supported 300 (such as a laptop computer), and the connecting member of the fourth rotating link and the appearance member 400 (such as the leg 500) is fixedly connected. The appearance member 400 can be a flexible and recoverable elastic plate. The reference numeral 600 in the figure is the rear decorative plate of the supported object.
