Synchronous rotation of multi-axis positioning structure

The invention relates to a pivot, in particular to a multi-segment positioning structure for synchronously rotating a double shaft.

According to the advancement of technology, liquid crystal display (LCD) has been widely used in electronic product display devices.

The liquid crystal display has the advantages of high image quality, small size, light weight, low voltage driving, low power consumption and wide application range, and thus has been widely used in portable televisions, mobile phones, notebook computers, desktop displays, and In consumer electronics or computer products such as projection TVs, it becomes the mainstream of displays; in the case of notebook computers, the liquid crystal display is fixed to the upper cover, and when the notebook computer is used, the upper cover is opened to reveal the liquid crystal display mounted thereon. The upper cover and the host computer are pivotally connected to open and close the upper cover relative to the computer mainframe.

Therefore, the pivot is one of the major reasons for determining the above-mentioned electronic products or computer products. In order to enable the screen casing and the keyboard casing to be flipped to the required angle according to the user's needs, the industry has developed a double pivot hinge, but Conventional double pivot hinges still have disadvantages in their construction and function.

Therefore, the inventor previously applied for a related dual pivot patent case capable of simultaneous multi-angle flipping and obtained a series of pivot patents to improve the lack of a conventional pivot, which can be rotated with a predetermined tightness. Can be flipped to the required angle as needed, but If the pivot can be in a predetermined position during the pivoting process, that is, when the cover of the notebook is closed or opened to a predetermined position (such as the cover is opened to a half position), the positioning function is generated, and the user's hand can be Tactile sensing positioning effect, in this way, will certainly improve the practicality of the pivot.

Therefore, the inventor did not dare to be complacent and based on the concept of continuous innovation of products. Based on the practical experience of designing and developing this product for many years, and actively researching and thinking, through numerous practical design experiments, this book has been The invention was produced.

The object of the present invention is to provide a multi-segment positioning of a synchronous rotating double shaft which can be positioned by the arc-face portion of the first pivot and the plane portion of the plane portion respectively during the pivoting process. structure.

For the above purposes, the present invention comprises a double shaft set, two positioning sleeves, two receiving members, and a positioning rod, wherein the double shaft group comprises a first pivot shaft, a second pivot shaft and at least two connecting members. The first pivot is a deformable material and has at least two first mounting slots, the first pivot shaft includes at least one arc surface portion, at least one planar portion, and the second pivot shaft has at least two second mounting slots, the connection The two sides of the member are respectively movably disposed in the first mounting groove and the second mounting groove; the positioning sleeve is a deformable material sleeved on the first pivot shaft and the second pivot shaft; the receiving member Connecting to the first pivot shaft and the second pivot shaft; the two ends of the positioning rod are connected to the receiving member and disposed between the first pivot shaft and the second pivot shaft, and the one side of the positioning rod has a side plane The side planar portion is in contact with the planar portion of the first pivot.

When the first pivoting causes the arc surface to contact the side plane portion of the positioning rod, the function of outwardly urging the positioning sleeve is generated, and when the first pivoting is rotated to bring the plane portion into contact with the side plane portion of the positioning rod, Produce a positioning function (the hand can have a tactile perceptual positioning effect), the first pivot plane is more Multi-position positioning can be achieved in a long time.
