Description

Hub and electronic device using the same

The present invention relates to a hinge (Hinge) connectable between two panels and an electronic device using the same, and in particular to a hinge for using a hinge bar at a pivotal joint of two panels And an electronic device using the hinge.

Existing electronic devices, such as mobile phones, notebook computers, tablet computers, etc., include two panels and two hinges connected between the two panels. Two boards are used to set up components such as screens and keyboards. The two plates are in a superposed or unfolded state by being relatively rotatable by the two hinges.

Referring to FIG. 8 and FIG. 9 , a conventional portable electronic device (such as a mobile phone or a notebook computer) includes a base (90, 90A), a hinge (91, 91A), and a cover (92, 92A). The cover (92, 92A) is pivotally connected to the base (90, 90A) by the hinge (91, 91A). In addition, a cover (93, 93A) is disposed outside the hinge (91, 91A) to make the appearance of the electronic device more beautiful.

This cover (93, 93A) is commonly referred to by those skilled in the art as a hinge bar (Hinge Bar), which is hereinafter referred to as a hinge bar. The length of the hinge strip (93, 93A) is shown in Figures 8 and 9 plus the length of the cover (92, 92A), which is approximately equal to the length of the entire base (90, 90A). But there is another kind of hinge bar, as shown in Figure 10. In FIG. 10, the cover body (92B) has the same length as the base (90B), and is pivotally connected to each other by a hinge (91B), and a hinge bar (93B) is disposed outside the hinge (91B). The appearance of the electronic device is more beautiful. The structure shown in Fig. 10, which is a notebook computer which is widely used now, can be pivoted by 90 degrees, or even 180 degrees, respectively, with the cover (92B) and the base (90B).

In the design of the notebook computer, as long as the hub bar is independently designed as a storage hub, the following problems occur. First, during the opening of the cover body (92, 92A), the hinge strip (93, 93A) is adjacent to the end of the cover body (92, 92A) and the rotational displacement of the cover body (92, 92A) Interference occurs, causing the user to fail to open the cover (92, 92A) smoothly. In order to solve the problem that the cover body (92, 92A) is not smoothly opened, the following two solutions are mostly used: First solution, as shown in FIG. 8, the hinge bar (93) is adjacent to the cover body (92). The end portion is provided with an inclined surface (94) to improve the interference of the edge of the hinge strip (93) in the past, so that the cover body (92) can be rotated along the center of the hinge (91). The inclined surface (94) moves smoothly. However, the design of the inclined surface (94) in the above makes the appearance of the electronic device not smooth enough, and affects the display of the design sense, and also affects the consumer's willingness to purchase.

The second solution is shown in Figure 9. The distance between the cover body (92A) and the hinge bar (93A) may be increased such that a radius of rotation of the cover body (92A) adjacent to an end edge of the hinge bar (93A) is greater than an end edge of the hinge bar (93A) to the hub Distance of the device. Therefore, the cover body (92A) can be prevented from being interfered by the end edge of the hinge bar (93A) during the pivoting movement, so that the smoothness of opening and closing of the cover body (92A) can be improved. However, such a spacing also fails to solve the problem that the appearance of the electronic device is not smooth enough.

The purpose of the present invention is to propose a hinge and an electronic device using the same, so that the two plates are not interfered by the hinge bar when rotated relative to each other, the use is smoother, and the appearance of the electronic device is smoother.

In order to achieve the above object, the present invention proposes a hinge comprising a cam member, two first rotating shafts, two connecting members, two sliding members and two elastic members. The two ends of the cam member are respectively provided with contour surfaces.

Each of the connecting members has opposite first ends and second ends, and the first ends of the connecting members are fixedly sleeved on the corresponding first rotating shafts. Each of the sliding members is slidably disposed on the corresponding connecting member, so that the sliding member is slidable between the first end and the second end of the connecting member, and each sliding member is provided with a guiding rod, and the guiding rod slides along the corresponding contour surface. Each of the elastic members is coupled between the second end of the corresponding connector and the corresponding slider.

In an embodiment of the hinge, the hinge further includes a linkage structure disposed between the two first rotating shafts to make the two first rotating shafts move together. The interlocking structure includes two first gears and two second gears. The two first gears are respectively fixedly sleeved on the two first rotating shafts. The two second gears mesh with each other and respectively engage the two first gears.

The bracket member and the cam member are disposed in parallel with each other, and the two first rotating shafts rotatably pass through the bracket member. The two second rotating shafts are disposed in parallel with the two first rotating shafts and are pivotally connected between the cam member and the bracket member, and the two second gears are respectively fixedly sleeved on the two second rotating shafts. Wherein the two first gears and the two second gears are located between the bracket member and the cam member.

In an embodiment of the hinge, the cam member has two opposite first side edges and two opposite second side edges, and the first side edges are adjacent to the two second side edges, and each of the first side edges is respectively contoured surface. The contoured surface includes two convex surfaces, two first concave surfaces, and a second concave surface. Each of the first concave surfaces is coupled between the corresponding convex surface and the corresponding second side. The second concave surface is connected between the two convex surfaces.

In an embodiment of the hinge, the second end of the connecting member is provided with a resisting plate extending along the axial direction of the first rotating shaft, and the side of the sliding member facing the second end of the connecting member extends along the radial direction of the first rotating shaft. There is a groove, one end of the elastic member is connected to the abutting plate, and the other end of the elastic member is disposed in the groove.

In an embodiment of the hinge, the connecting member is provided with a first sliding slot, and the guiding rod is slidably disposed through the first sliding slot.

In an embodiment of the electronic device, the electronic device further includes four cover plates to cover the slots of the two plates, respectively.

The creation passes through the contour surface of the cam member. When the two plates are relatively rotated and the relative angle is close to 90 degrees, the contour surface pushes the guide bar to slide the sliding member toward the second end of the connecting member (the sliding member compresses the elastic member), thereby driving The plate member slides toward the second end of the connecting member, that is, the two plates are respectively away from the pivotal joint of the two plates while being relatively rotated, so that the two plates can be close to the shell member and the hinge bar without being interfered by the two members; When the two plates are relatively rotated and are separated from each other by 90 degrees, the contoured surface pushes the guide bar and the compressed elastic member provides an elastic force to cause the sliding member to slide toward the first end of the connecting member to be reset, that is, the two plates are relatively rotated simultaneously It will also be close to the pivotal joints of the two plates, so that the two plates can be close to the case and the hinge bar without being interfered by them, so that the use is smoother.
