Auxiliary supporting structure provided with gear frame used for transmission and double-shaft hinge

Abstract

The invention discloses an auxiliary supporting structure provided with a gear frame used for transmission and a double-shaft hinge. The auxiliary supporting structure comprises two spindles, two guide connecting plates, two transmission gears and the gear frame. The transmission gears are fixed to the corresponding spindles. The guide connecting plates are arranged on the two spindles in a sleeving mode and can circumferentially rotate relative to the two spindles. The gear frame is clamped between the two guide connecting plates and is connected with the two guide connecting plates through sliding blocks and guide sliding grooves. The gear frame circumferentially surrounds the two transmission gears. A first rack in engaged transmission with one transmission gear is formed on one side ofthe gear frame, and a second rack in engaged transmission with the other transmission gear is formed on the other side of the gear frame. An auxiliary connecting piece used for arranging and pushingan auxiliary screen is arranged on the outer side of the gear frame. By the adoption of the auxiliary supporting structure, 360-degree synchronous rotation of the two spindles is achieved, the supporting requirement of electronic products such as a notebook computer with an auxiliary screen is met, and the development of thin notebook computers is facilitated.

Description

technical field [0001] The invention relates to a hinge applied to electronic products such as notebook computers, in particular to a gear frame transmission auxiliary support structure and a biaxial hinge. Background technique [0002] A hinge, also known as a damping shaft, is a connecting element that can provide mutual rotation. It is mainly used between rotating parts and its substrate. At present, it is widely used in various digital products and electronic products, such as notebook computers. Through the hinge The rotation of the notebook computer can realize the opening and closing function between the body of the notebook computer and the display screen. At present, in the commonly used biaxial hinges, when one shaft core rotates, the other shaft core is clamped, and the two shafts are opened and closed sequentially. In order to achieve 360-degree synchronous rotation of the two shafts, there are also biaxial hinges that use multiple gears for combined transmissio...

Problems solved by technology

In order to achieve 360-degree synchronous rotation of the two shafts, there are also biaxial hinges that use multiple gears for combined transmission. The axes of the multiple gears are in the same direction as the axes of the two shafts. Shaft synchronous reverse opening and closing function, and due to the use of more gears, the distance between the two shaft cores is relatively long, which limits the development of thinner electronic equipment such as notebook computers

In addition, with the development of more humanized design of electronic products such as notebook computers, a notebook computer with an auxiliary screen can meet people's needs for multi-screen display, and users can browse different windows without switching screens. Here The auxiliary screen is usually embedded in the base of the notebook computer near the hinge. It is necessary to open the auxiliary screen while opening the main screen, and to avoid interference between the auxiliary screen and the main screen while opening the auxiliary screen. It poses a new challenge to the existing two-axis hinge, that is to say, the existing two-axis hinge must meet the following functions, that is, it can promote the opening of the auxiliary screen while meeting the development needs of thin and light electronic products, while the existing two-axis hinge Therefore, it is very necessary to develop and design a two-axis hinge that can promote the opening of the auxiliary screen and facilitate the thinning of the notebook computer.
