Pivot unit for electronic products

Abstract

The present invention relates to a kind of pivot device which apply to electric product, this pivot device contains: a first cylinder is fixed on the first part, which circumference surface has undulation and center of the top surface has a first fixed hole; a first bridging is fixed on the second part, which top surface is set to cooperate circumference surface of the first cylinder and has flexibility; a fixed base, which is fixed on the second part and has a second fixed hole; a fixed revolution axis, which passes through the second fixed hole of the fixed baes and the first fixed hole of the first cylinder's top surface to makes circumference surface of the first cylinder to rotate along with top surface of the first bridging, and provides positive-direct force which cooperate closely.

Description

technical field [0001] The invention relates to a pivoting device, especially a pivoting device suitable for vehicle electronic products. Background technique [0002] With the thinness, lightness, size and diversification of electronic products, many electronic products have developed models that can use the DC power supply on the car, which is usually 12 volts. Such as figure 1 As shown in , it is a schematic diagram of the common structure of an electronic product that uses DC power on a car, wherein the first part 11 is a car power plug that can be inserted into the cigarette lighter jack, and the second part 12 is the main body of the electronic product. Common devices include hands-free bases for mobile phones, reading lights for cars, fans, speakers, and even LCD monitors. And in order to be able to respond to the cigarette lighter socket, the gear lever and the instrument panel setting in different positions in various vehicles, the first part 11 is usually designe...

AI Technical Summary

Problems solved by technology

and figure 1 The pivoting mechanism 13 shown in is a common and commonly used means. In order to provide the user with a sense of paragraph when rotating and to ensure that it can be firmly engaged when fixing, the contact surface of the pivoting mechanism 13 is provided with radial Concavo-convex structures 131, 132, but this pivot mechanism 13 has a serious lack of inconvenience in use, that is, when the user wants to adjust the use angle, he must first loosen the screw 133 to facilitate adjustment, and then screw 133 after the adjustment is completed. Lock to re-secure

And such complicated movements will cause trouble when driving

In addition, the power cord in the conventional structure is often exposed from the hole of the pivot mechanism 13, which also affects the safety of use to a certain extent.
