Abstract
Description
Technical Field
[0001] The utility model relates to a virtual rotation center hinge on a portable device, in particular to a support hinge used therein. The portable device may be a notebook computer, a mobile phone, a pad, etc. Background Art
[0002] A support hinge for mobile phones, tablets, computers, and the like is installed behind the screen or tablet and connected to a bracket. When the supported object is in an open position at different angles, it supports the supported object from behind. This type of hinge used in portable devices is very small, only a few millimeters high. Despite its small size, it still needs to ensure mechanical strength and rotational force. Currently used virtual rotation center hinges include a mounting base and a rotating assembly with the virtual center as its axis. The rotating assembly is rotatably mounted on the mounting base and connected to an elastic mechanism at a position offset from the axis via a friction shaft. The elastic mechanism has a coiled ring at the first end, which clamps the friction shaft and contributes to the rotational force. The elastic mechanism has a fixed connecting sleeve at the second end, which is connected to the connecting shaft via the fixed connecting sleeve. The connecting shaft passes through a slot in the mounting base and can slide along the slot. To facilitate assembly, the slot needs to be a through slot. Even so, the connecting shaft needs to pass through the slot and also have an interference fit with the fixed connecting sleeve, making assembly difficult. The through slot significantly affects the mechanical strength of the mounting base, increasing the risk of fracture of the upper and lower slot walls. Furthermore, it is difficult to reduce the size of the hinge. Utility Model Content

[0020] Refer to the accompanying drawings, refer to the accompanying drawings. The utility model provides a virtual rotation center hinge on a portable device, including a mounting seat, a rotating component with a virtual center as the axis, and an elastic mechanism. The rotating component is rotatably mounted on the mounting seat, and the rotating component is connected to the elastic mechanism through a friction shaft 3 at a position deviated from the axis. A coil 4 is provided at the first end of the elastic mechanism, and the coil 4 is a jacket with an axial gap and elasticity. The coil 4 clamps the friction shaft 3 and contributes to the rotational force value. The mounting seat is provided with a guide groove, and the second end of the elastic mechanism is slidably connected to the guide groove through a connecting shaft 5. The mounting seat is assembled from a split left main body 11 and a right main body 12, and can be specifically connected by screws or other connection methods. Preferably, the connecting screws include a transverse screw 13, which can improve the strength of the mounting seat for the hinge of the utility model. Further, as shown in the accompanying drawings, the front and rear ends of the left main body 11 and the right main body 12 are connected by transverse screws, and the directions of the transverse screws at the front and rear ends are opposite.
[0021] The guide grooves are respectively provided on the left main body 11 and the right main body 12, and the guide grooves are provided as blind guide grooves 14 with groove bottoms. The strength of the upper groove wall 141 and the lower groove wall 142 is strengthened by the groove bottom 140 of the blind guide groove, so as to improve the performance of preventing the upper groove wall 141 and the lower groove wall 142 from being broken by external forces in the upper and lower directions. The connecting shaft 5 can be inserted into the blind guide groove 14 with groove bottoms from between the left main body 11 and the right main body 12 and installed before the mounting seat is assembled.
[0022] The rotating component is composed of a first component 21 and a second component 22 that are slidably connected. The first component 21 and the second component 22 are slidably connected through the left and right first arc-shaped sliders 211 and the first arc-shaped track 221 therebetween, and the second component 22 and the mounting seat are slidably connected through the left and right second arc-shaped sliders 222 and the second arc-shaped track 102 therebetween; the centers of the left and right first arc-shaped sliders 211 and the first arc-shaped track 221, and the left and right second arc-shaped sliders 222 and the second arc-shaped track 102 are the axis, and the yield structure of the curl 4 is provided on the second component 22. By increasing the wall thickness of the elastic mechanism curl and reducing the diameter of the friction shaft, a high rotational force value can be ensured and the height of the mounting seat can be reduced, thereby reducing the height of the entire hinge, which is of great significance for the thinning design of the application object. In this embodiment, the total height of the hinge can be reduced from the previous 5.7 mm to 4.2 mm.
[0023] The first component 21 is provided with a left side and a right side structure, and the left side and the right side structure of the first component 21 are respectively provided with a left and a right first arc slider 211; the second component 22 is provided with a left side and a right side structure, and the left side and the right side structure of the second component 22 are respectively provided with a left second arc slider 222 and a first arc guide rail 221 and a right second arc slider 222 and a left first arc guide rail 221, and the second arc slider 222 is provided on the back side of the first arc guide rail 221 on the same side; the left main body 11 and the right main body 12 are respectively provided with a left and a right second arc track 102; the friction shaft 3 is connected between the left side and the right side structure of the first component 21; a connecting structure 220 is provided between the left side and the right side structure of the second component 22, and the give way structure is a give way notch 223 on the connecting structure 220, and the elastic mechanism is provided as a connecting rod 6; a cavity 101 is provided in the mounting seat for the movement of the connecting rod 6 and the rotating component.
[0024] The first end of the connecting rod 6 is provided with the curling circle 4 which is integrated with the connecting rod 6, and the second end is provided with the connecting shaft 5 which is integrated with the connecting rod 6. At the second end, it is an integrated structure with a step 61, and the left and right sides of the second end protrude the connecting shaft 5 from the step portion to the left and right sides respectively.
[0025] The hardness of the elastic mechanism (the integral part of the connecting rod 6, the curling circle 4 and the connecting shaft 5) is higher than that of the mounting seat. In the present invention, the material of the mounting seat can be zinc alloy and can also meet the life requirements, greatly reducing the cost.
[0026] The hardness of the first component 21 is comparable to that of the elastic mechanism, and a limiting structure for the maximum opening angle of the first component is provided between the elastic mechanism and the first component, which are the parts indicated by the figures 211 and 41 in this embodiment.
[0027] The second component 22 has a lower hardness than the first component and can be made of the same material as the mounting base. The rotation of the second component 22 can rely on the friction between it and the first component 21, and when closed, it can be finally reset by an adjacent position on the portable device.
