Description

Technical Field

[0001] The present application relates to the field of keyboard structures, and in particular to a magic control keyboard structure. Background Art

[0002] In modern electronic product design, multifunctional hinge structures have become a key component, especially in foldable mobile phones, laptops and tablets. With the continuous advancement of technology, people have put forward higher requirements for the convenience and stability of keyboard operation. In order to meet these requirements, the design of the hinge structure has become particularly important. An efficient and reliable hinge structure can not only improve the user experience, but also enhance the overall performance of the device.

[0003] The keyboard hinge assembly currently widely used in the market is mainly composed of a rotating shaft, a fixing part, a torsion spring, a flip part and a limit part. This design uses the elastic force of the torsion spring to automatically reset the rotating shaft or maintain a specific angle, thereby meeting the opening and closing requirements of the keyboard. Existing structures usually include a single torsion or damping mechanism to control the opening and closing speed and position of the keyboard. Specifically, the torsion spring structure generates resistance through its elastic force when the keyboard is opened or closed, allowing it to be maintained at any angle, thereby achieving convenience in operation. In addition, the torsion spring design can also ensure that the device is not easily accidentally opened in a closed state, increasing the safety of use.

[0004] However, due to the inherent characteristics of the torsion spring structure, the existing hinge structure often has difficulty in providing a stable self-locking mechanism during the closing and opening process. This results in the user needing a lot of force when trying to open the keyboard, or even needing to use both hands, and the keyboard part is prone to move with the hinge, increasing the difficulty and inconvenience of operation. Therefore, how to provide a hinge structure that can achieve stable self-locking and is easy to operate has become an urgent problem to be solved. Summary of the invention

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-11 This application is described in further detail.

[0039] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should be the common meanings understood by those skilled in the art to which this application belongs. The "first", "second" and similar words used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0040] The inventor of the present application has found that in the design of modern electronic products, a multifunctional hinge structure has become a key component, especially in foldable mobile phones, laptops and tablet computers. With the continuous advancement of technology, people have put forward higher requirements for the convenience and stability of keyboard operation. In order to meet these requirements, the design of the hinge structure has become particularly important. An efficient and reliable hinge structure can not only improve the user experience, but also improve the overall performance of the device. The keyboard hinge assembly widely used in the market is mainly composed of a rotating shaft, a fixing member, a torsion spring, a flip member and a limiter. This design realizes the automatic resetting of the rotating shaft or maintains a specific angle through the elastic force of the torsion spring, thereby meeting the opening and closing requirements of the keyboard. The existing structure usually includes a single torsion or damping mechanism to control the opening and closing speed and position of the keyboard. However, due to the inherent characteristics of the torsion spring structure, the existing hinge structure is often difficult to provide a stable self-locking mechanism during the closing and opening process. This results in the user may need a large force when trying to open the keyboard, or even need to operate with both hands, and the keyboard part is easy to move with the hinge, which increases the difficulty and inconvenience of operation.

[0041] To this end, the present application mainly adopts the following scheme to provide a shaft structure that can achieve stable self-locking and convenient operation, thereby improving the user's operating convenience and the overall performance of the device. The present application is further described in detail below.

[0047] Reference Figure 2 and Figure 3, a concave-convex matching mechanism 7 is provided between the second drive sleeve 62 and the second cam sleeve 63 and can rotate relatively. When the convex position of the concave-convex matching mechanism 7 is opposite to the convex position, it is the closed position of the flip member, and when the concave position and the convex position of the concave-convex matching mechanism 7 are plugged into each other, it is the open position of the flip member.

The second elastic component 61 is sleeved on the rotating shaft and acts on the second drive sleeve 62 to drive the second drive sleeve 62 to have a tendency to move in the direction close to the second cam sleeve 63. In the closing stage, the end of the first drive sleeve 52 abuts against the end of the first flange 71 to achieve the closed anti-locking function. In the transition stage, the inner side walls of the concave-convex matching mechanism 7 abut against each other to achieve the free hovering function at any position.

[0049] Reference Figure 4 The second flange 73 includes a second end face 731, which can be a plane, a curved surface or an arc-shaped surface. A plurality of second functional slopes 9 with different slopes are provided on both sides of the second flange 73. A second fillet 93 is provided between two adjacent second functional slopes 9. The surface of each second functional slope 9 is a plane, a curved surface or an arc-shaped surface. In this embodiment, the second functional slope 9 on one side of the second flange 73 includes a sixth slope section 91, and the second functional slope 9 on the other side of the second flange 73 includes a seventh slope section 92, wherein the sixth slope section 91 is a steep slope, and the seventh slope section 92 is a gentle slope. Similarly, the inclination of the steep slope is greater than that of the gentle slope, so that the automatic hovering function is realized on the gentle slope, and the automatic opening to the end position can be realized within the range of the steep slope when no external force is applied, and the end point self-locking and closed anti-locking functions are realized after opening.

[0050] Reference Figure 2 and Figure 3 Specifically, one end of the rotating shaft 4 of the second rotating shaft structure is inserted into one end of the first flip member 10 and is fixedly connected to the first flip member 10.

The shape of the first flange 71 is adapted to the shape of the first groove 72, so that the first flange 71 and the first groove 72 can be precisely engaged, thereby providing stability and reliability during the opening and closing process.

[0054] Reference Figure 5 and Figure 6 Specifically, in the closing stage, the end of the first drive sleeve 52 abuts against the end of the first flange 71 to achieve the closed anti-locking function.

[0055] Reference Figure 6 The first flange 71 includes a first end surface 711, which is a plane, a curved surface or an arc surface. When the first end surface 711 of the first flange 71 abuts against the end of the first drive sleeve 52, the friction between the first end surface 711 and the first drive sleeve 52 can achieve the suspension of the first flip member 10. Both sides of the first flange 71 are provided with a plurality of first functional slopes 8 with different slopes, and the surface of each first functional slope 8 is a plane, a curved surface or an arc surface. The first end face 711 of the first flange 71 is a plane, curved surface or arc-shaped surface with a small inclination, which can ensure that the end of the first drive sleeve 52 is accurately abutted against the end of the first flange 71 in the closing stage, thereby ensuring the effective implementation of the closed anti-locking function; the multiple first functional slopes 8 with different inclinations arranged on both sides of the first flange 71 can provide a variety of rotation states according to different usage scenarios, and realize smooth transition and free hovering function at any position in the opening stage and the transition stage, especially when the second slope section 82 is a steep slope, it can automatically open to the end position within the steep slope range when not affected by external force, thereby providing better operating experience and stability.
