Connecting piece and electronic device with same

Abstract

The invention provides a connecting piece and an electronic device with the same. The connecting piece is used for rotationally connecting the first part with the second part of the electronic device. The connecting piece comprises a first bevel gear fixedly connected with the first part of the electronic device, a second bevel gear fixedly connected with the second part of the electronic device, and an intermediate bevel gear engaged with the first bevel gear and the second bevel gear. The axis of the intermediate bevel gear and the axes of the first bevel gear and the second bevel gear are orthogonal, and accordingly through rotation of the intermediate bevel gear, the first bevel gear and the second bevel gear can rotate synchronously so that the first part and the second part of the electronic device can rotate relatively. Since the intermediate bevel gear is an enveloping surface gear, the first bevel gear and the second bevel gear are engaged with the intermediate bevel gear in a linear contact mode.

Description

technical field [0001] The present invention relates to a connector and an electronic device with the connector. Background technique [0002] Rotary connectors are widely used in various electronic devices to realize the mutual rotation between the first part and the second part of the electronic device, for example, for a notebook computer, there is a rotating connection between the display part and the keyboard part. The connecting piece enables the display screen part to rotate freely relative to the keyboard part, so that the user can view the content of the display screen at an appropriate angle. [0003] In order to achieve a large-angle mutual rotation between the two parts of the electronic device, such as a free rotation of up to 360 degrees, in recent years, some designers have proposed to use a rotating connection composed of cross-axis helical gears to achieve the aforementioned large-angle rotation . Specifically, refer to figure 1 , which is a schematic dia...

Problems solved by technology

[0004] However, the aforementioned connection consisting of three helical gears also has its disadvantages

Specifically, the mutual meshing of the three cross-axis helical gears is basically carried out in the form of point contact. In this way, due to the limitation of machining accuracy and assembly technology level, sometimes there will be problems of uneven rotation or torsional instability. At the same time, due to the It is a point contact, which poses a high challenge to the strength and wear resistance of the helical gear during the torque transmission process

[0005] Therefore, there is a need to provide a new type of rotary connection, which on the one hand can realize a large angle of relative rotation, and on the other hand can at least overcome the above-mentioned connection composed of cross-axis helical gears in the prior art issues such as smooth force transmission and wear resistance
