Description

Rotatable connection structure

Technical field

Background technique

A hinge, also known as a hinge, is a mechanical device used to connect two solid bodies and allow relative rotation between the two. The hinge may be constructed from removable components or from foldable material.

Hinge structures are widely used in various fields. For example, notebook computers use a hinge structure to connect the display part and the keyboard part, so that the notebook computer can be opened, closed, and folded.

For the field of electronic equipment, it is usually necessary to set cables at both ends of the hinge. For example, a notebook computer needs to pass the connecting cable of the display through the hinge, so that the display can communicate with the motherboard provided with the keyboard part through the connecting cable. According to the existing technology, Wrapping the cable around the hinge shaft part enables the purpose of arranging the cables at both ends of the hinge.

In the prior art, the purpose of arranging cables at both ends of the hinge can be achieved by winding the cable around the rotating shaft of the hinge. However, the above connection method has the following shortcomings:

3. In most cases, equipment manufacturers set mechanical limits on the hinges to limit the rotation angle of the hinges. For example, the maximum opening and closing angle between the screen part and the keyboard part of most laptops is 100°. If the limited angle is exceeded, it will Damage the equipment, so equipment manufacturers need to customize hinges with mechanical limit structures. Different hinges need to be customized for different opening and closing angles. The cost of customization is high, which increases the overall cost of the equipment.

Therefore, how to adaptively adjust the opening and closing angle of the hinge is an urgent technical problem that those skilled in the art need to solve.

The above rotatable connection structure will be described below with a specific embodiment.

There is a fixed end adjustment lever and a movable end adjustment lever inside the rotating shaft. When the hinge is in normal working condition, the fixed end and the movable end can rotate freely without pulling the internally connected cables;

The hinge can adjust the opening and closing angle. In the adjustment mode, the opening and closing angle of the hinge can be adjusted by adjusting the movable end adjustment lever and the fixed end adjustment lever. The rotatable connection structure provided by this application can be adjusted according to needs without customization. Its internal specific structure and principles are as follows:

As shown in Figure 2, the connecting wire penetrates from the fixed end, winds a certain number of turns on the fixed piece, then passes through the fixed end connecting ear and the movable end connecting ear in sequence, and then winds a certain number of turns on the tension piece, and finally from The movable end comes out and the tension piece is in a pre-tensioned state;

When the hinge rotates, when the direction of rotation is consistent with the winding direction (for example, the movable end rotates clockwise in the direction shown in Figure 2), the tension piece moves closer to the axis, and the tension spring supporting the tension piece compresses, otherwise, the tension piece The tensioning piece moves away from the axis, and the spring supporting the tensioning piece relaxes.

Therefore, when the hinge rotates within the rotatable angle, the internal cable is always in a tensioned state. When rotating in the winding direction, the tension piece is compressed, the diameter of the tension area is reduced, and the number of turns of the cable is increased, making the wire The cable remains in tension and will not pull the cable; on the contrary, when rotating in the opposite direction of the winding direction, the tension piece relaxes, the diameter of the tension area increases, and the number of winding turns of the cable decreases, so that the cable remains in a tensioned state.

Figure 3 shows the internal structural diagram of the rotating shaft. To sum up, the rotatable connection structure provided by the present application can keep the cable in a tensioned state when the hinge rotates, and will not tear the cable.

The adjustable angle range of the hinge is adjusted by the ratio of the number of turns wound on the tensioning piece and the fixed piece. Specifically, the diameter of the tensioning area is reduced by the same. If the number of turns wound on the tensioning piece is greater, the adjustable range will be larger. ; On the contrary, the fewer the number of turns wrapped around the tensioning piece, the smaller the adjustable range.

The process and principle of adjusting the hinge opening and closing angle are as follows:

During the normal operation of the hinge, the tensioning area and the fixed area rotate synchronously. When the hinge opening and closing angle is adjusted, the tensioning area and the fixed area rotate independently. The cable wrapped on the tensioning piece is pulled out from the movable end through control, and the cable wrapped on the fixed piece is Pull out the cable from the fixed end, adjust the length of the fixed end connecting lug and the cables on both sides of the movable end connecting lug according to the required opening and closing angle. If a larger opening and closing angle is required, adjust the length of the cable outside the movable end connecting lug. The length is longer. On the contrary, if the opening and closing angle is smaller, the length of the cable outside the fixed end connecting ear will be shorter. Correspondingly, the length of the cable outside the movable end connecting ear will be wound around the tension piece more times. Based on the above analysis, the openable angle will be increased.

As shown in Figure 4, pushing the tension piece adjustment rod can make the tension piece rotate independently with the internal rotating shaft, so the position of the movable end connecting ear can be adjusted. The tension piece adjustment rod and the housing are provided with slide grooves and positioning grooves. , the connecting shaft and spring supporting the tensioning piece slide in the chute. The positioning groove can limit the position of the connecting shaft. The positioning shaft is fixedly connected to the tensioning piece. The locking spring can maintain the clamping force of the positioning groove and push the tensioning piece to adjust. The rod will separate the two parts of the positioning groove and lose the positioning effect. At this time, the tension piece and the internal rotating shaft rotate independently. The positioning effect will be restored after the tension piece adjustment rod is reset.

As shown in Figure 5, during normal operation of the hinge, the end of the movable end adjustment rod is square, and the square part cooperates with the fixed end and the movable end at the same time, so that the fixed end and the movable end rotate synchronously, and the square part in the middle of the fixed end adjustment rod Matches the rounded part inside the fixed end and does not transmit torque.

There are following steps to adjust the opening and closing angle:

(1) First push the fixed end adjusting rod and compress the adjusting spring so that the square section in the middle of the fixed end adjusting rod matches the square hole inside the fixed end. At this time, rotating the fixed end adjusting rod can control the rotation of the fixed end;

(2) Then pull back the movable end adjustment rod so that the direction section of the end of the movable end adjustment rod is separated from the fixed end. At this time, rotating the movable end adjustment rod can independently rotate the movable end, and rotating the fixed end adjustment rod can independently rotate the fixed end. ;

(3) Rotate the fixed end and the movable end respectively to pull out the cable;

(4) Adjust the length of the cables on both sides of the fixed end connecting lug and the movable end connecting lug according to the required opening and closing angle;

(5) Rewind the cable through the fixed end adjustment lever and the movable end adjustment lever, and reset the adjustment lever.

The above are only specific embodiments of the present application. It should be understood that the protection scope of the present application is not limited thereto. Any person familiar with the technical field can easily think of various etc. within the technical scope disclosed in the present application. Effective modifications or substitutions shall be included in the protection scope of this application.
