Rotary shaft-support linkage device and electronic device using same

Abstract

The invention discloses a rotary shaft-support linkage device and an electronic device using the same. The rotary shaft-support linkage device comprises a support, a rotary part arranged on a fixed-connection shaft core, fixed-connection members and a rotating shaft transmission part. The support comprises a support body and a support sleeve. Each of the fixed-connection members comprises a fixed-connection member body and a fixed-connection sleeve. The rotating shaft transmission part comprises a shaft core, a cam, a concave wheel, a first elastic member, a driving wheel, a locking element, asecond elastic member and a torsion assembly. A driving wheel has a formed driving block, and the cam has a formed passively-moving block is formed; the joint surfaces of the cam and the concave wheel are both provided with two bumps and a transition slope surface; and the two bumps on the joint surfaces of the cam and the concave wheel are in plane contact. The rotary shaft-support linkage device of the invention can solve the problem that a keyboard base is lifted up when a host is pushed open; when the host is pushed open, the support props open and is locked; after the host is pushed open, the host can rotate freely within a set angle range relative to the support and the keyboard base, and can stay at any angle; and when the host is closed, the support can be unlocked and is driven to lift up so as to facilitate the manual closing of the support.

Description

technical field [0001] The invention relates to components such as a rotating shaft and a bracket of an electronic device, in particular to a linkage device of a rotating shaft and a bracket and an electronic device using the same. Background technique [0002] The two-in-one tablet computer is to combine the tablet computer and the notebook computer to form a two-in-one computer that has both the touch of the tablet computer and the function of the notebook computer with a keyboard. The 2-in-1 computer is relatively thin and portable, which is convenient for users to hold, play games, and watch movies. It is very convenient because it has a keyboard for fast input. Needed to play games. Usually, the two-in-one computer integrates the main unit and the screen as a rotating part, and uses the keyboard base as the base. This structure causes the weight of the main unit (rotating part) to greatly exceed the weight of the keyboard base (base). When the rotating opening and clo...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention proposes a rotating shaft and bracket transmission device and an electronic device using it, which can solve the problem of bringing up the keyboard base when the host is pushed away, and can bounce the bracket and lock it when the host is pushed away. After the bracket is opened, the host can rotate freely within the set angle relative to the bracket and the keyboard base, and stay at any angle, and when the host is closed, the bracket can be unlocked and the bracket can be lifted up, which is convenient for manual closing of the bracket
