Abstract
Description
A sliding hinge for portable electronic devices Technical Field
[0001] This invention relates to a sliding hinge for use in portable electronic devices, which may be wearable devices such as AR / VR glasses. Background Technology
[0002] For portable electronic devices, there is a need for sliding connection structures, such as the focusing of AR / VR glasses. Generally, a sliding rail pair is used to achieve the sliding connection. A guide rail is set on one connecting plate, and the side of another connecting plate slides to the guide rail. This sliding connection structure has a relatively large amount of wobbling in the non-sliding direction, which affects the user experience. Some auxiliary structures are needed to reduce the gap, but it is difficult to control and it is easy to be too tight, affecting the feel. Summary of the Invention
[0003] The purpose of this invention is to provide a sliding hinge for portable electronic devices, which effectively reduces wobbling in the non-sliding direction and improves the user experience. To this end, this invention adopts the following technical solution:
[0004] A sliding hinge for portable electronic devices includes a first mounting body and a second mounting body, the first mounting body and the second mounting body being able to slide relative to each other, characterized in that the sliding hinge includes a cross roller slide rail, a first guide rail of the cross roller slide rail is connected to the first mounting body, a second guide rail is connected to the second mounting body, and a cross roller is disposed between the first guide rail and the second guide rail, the cross roller being mounted on a cross roller frame.
[0005] Based on the above technical solutions, the present invention may also employ the following further technical solutions, or combine these further technical solutions:
[0006] The back of the first guide rail is provided with an inclined surface, and the corresponding first mounting body is provided with a mating inclined surface. The first mounting body is provided with an adjustment elongated hole, and the position of the first guide rail is adjustablely fixed on the first mounting body. And / or, the back of the second guide rail is provided with an inclined surface, and the corresponding second mounting body is provided with a mating inclined surface. The second mounting body is provided with an adjustment elongated hole, and the position of the second guide rail is adjustablely fixed on the second mounting body.
[0007] A damping mechanism is also provided between the first mounting body and the second mounting body to increase sliding resistance.
[0008] The damping mechanism includes a rack and a gear. The gear is connected to a gear shaft via a reed tube. The gear shaft is connected to one of a first mounting body and a second mounting body. The rack is connected to the other of the first mounting body and the second mounting body. The gear and rack are meshed together.
[0009] With the sliding direction as the Y direction, the first and second mounting bodies also have Z-direction and X-direction limiting structures on both sides, serving as safety protection structures in the Z and X directions.
[0010] The limiting structure includes grooves on both sides of one of the first mounting body and the second mounting body, and a side of the other of the first mounting body and the second mounting body, wherein the side is inserted into the groove for limiting engagement.
[0011] The groove wall is also provided with a Y-direction travel limiting structure, and the other of the first mounting body and the second mounting body is provided with a limiting engagement structure that cooperates with the Y-direction travel limiting structure near its side.
[0012] The cross roller frame is a frame structure made of metal sheet through sheet metal fabrication, including several roller mounting holes and roller support plates formed on the surface of the holes through sheet metal, which are aligned with the inclination direction of the rollers.
[0013] By employing the technical solution of this invention, the amount of swaying in the non-sliding direction can be reduced, the sliding fit is precise, and furthermore, the clearance can be easily adjusted using the inclined surface fit according to user requirements, and a damping mechanism can also be applied. This provides a better user experience. Attached Figure Description

[0020] Referring to the accompanying drawings, the present invention provides a sliding hinge for portable electronic devices, comprising a first mounting body 1 and a second mounting body 2, which are capable of sliding relative to each other. The first mounting body 1 and the second mounting body 2 are connected to two objects in the portable electronic device that need to slide relative to each other. The first mounting body 1 and the second mounting body 2 can be a mounting plate, a mounting bracket, or a mounting base.
[0021] The sliding hinge includes a cross roller slide rail, which comprises a first guide rail 31, a second guide rail 32, multiple cross-arranged rollers 33, and a roller mounting bracket 34. The axes of adjacent rollers 33 are perpendicular. The first guide rail 31 is connected to the first mounting body 1, and the second guide rail 32 is connected to the second mounting body 2. The cross rollers 33 are arranged between the first guide rail 31 and the second guide rail 32 and are mounted on the cross roller bracket 34. The first guide rail 31 and the second guide rail 32 are respectively provided with V-shaped guide grooves 310 and 320. The V-shaped guide grooves 310 and 320 have mutually perpendicular side guide groove surfaces for engaging with the two inclined rollers in the cross rollers 33. The cross roller slide rail makes the axis of the roller perpendicular to the sliding direction and inclined to the first mounting body 1 and the second mounting body 2. The cross roller frame 34 can be a frame structure formed by sheet metal fabrication of a metal plate, including a number of roller mounting holes 341 and roller support plates 342 formed on the surface of the holes by sheet metal, which are aligned with the inclination direction of the rollers.
[0022] The second guide rail 32 has a bevel 321 on its back side, and the corresponding second mounting body 2 has a mating bevel 21. The second mounting body has an adjustment elongated hole 22. The second guide rail can move back and forth along the bevel and is fixed to the second mounting body 32 in an adjustable manner by screws and the position of the adjustment elongated hole 22. This allows for convenient stepless adjustment of the gap between the second guide rail and the first guide rail, that is, the gap between the second guide rail and the roller 33.
[0023] A damping mechanism is also provided between the first mounting body 1 and the second mounting body 2 to provide sliding resistance and improve the feel of operation. Based on the cross roller slide rail 3, the relative sliding movement of the first mounting body 1 and the second mounting body 2 is smooth, allowing the damping mechanism to perform better. In this embodiment, the damping mechanism includes a rack 41 and a gear 42. A spring tube 43 is provided in the shaft hole of the gear 41, which is connected to the gear shaft 44. The gear shaft 44 is connected to the second mounting body 2, and the rack 41 is connected to the first mounting body 1. The gear 42 and the rack 41 are meshed together. The spring tube 43 is a non-closed tube that can elastically open and close, clamping the gear shaft 44. A connecting handle 45 is provided on one side of the spring tube 43, which is engaged with the shaft hole.
[0024] With the sliding direction as the Y-axis, the first mounting body 1 and the second mounting body 2 also have Z-axis and X-axis limiting structures on both sides, serving as safety protection structures in the Z-axis and X-axis directions. These can be grooves 23 on both sides of the second mounting body 2 and side edges 11 of the first mounting body 1, with the side edges 11 inserted into the grooves 23 for limiting engagement. The groove wall 24 of the groove 23 is also provided with a Y-axis travel limiting structure (e.g., a protrusion 25), and a limiting engagement structure 12 (e.g., a limiting groove) that engages with the Y-axis travel limiting structure is provided near the side of the first mounting body 1.
