Shaft structure of electronic device

The present invention provides a rotating shaft structure of an electronic device, in particular, a joint between the base of the body and the main body is a rotating shaft device, and the rotating shaft of the rotating shaft device is coupled with the friction wheel assembly to cooperate with the damping mechanism to adjust the torque of the rotating shaft. Or closed angles, and have the effect that the action is indeed and more stable and less prone to sloshing.

According to today's electronic technology, the electronic technology is growing at an ever-changing speed, making electronic devices continue to evolve, and moving toward the development of computing power, speed and volume miniaturization. With the popularity of computers and networks, in addition to the general family or company Using computers and the Internet, even in stores, restaurants and other places can see the application of computers and networks, and because the retail industry is moving towards the chain system, there are operators using Point on Sale. POS), Electronic Order System (EOS) and Computer Assistant Order for cash register, barcode scanning, invoice or receipt opening, ordering, providing the latest news, product information, member information, sales analysis Processing to save a lot of manpower and the cost of operating.

In addition, the general electronic device often uses the rotating shaft device as a display, a panel or an outer cover to be pivotally positioned and used with the main body and the base, and the auxiliary cover and the base are stably opened. The function of closing or adjusting the angle of rotation; in addition, different types of shaft devices have different structures and assembly methods, and their functions and uses are also very different, and as the electronic devices are widely used, the early shaft devices are also There are many defects. For example, when the LCD screen is turned on, it is easy to cause the rotation angle to exceed the predetermined range due to excessive force, and the internal soft board or cable may be damaged or damaged, or the LCD screen may be directly closed. There are many problems caused by the failure of the pedestal to cause damage, damage or malfunction. Many manufacturers have improved the shaft device for the above problems, which can improve the lack of torque and improve the operation of the electronic device. The problem is that the structure of the shaft device is relatively complicated and the dimensional accuracy of the forming and molding is high, which is not conducive to mass production, which will greatly increase the cost of manufacturing, which is the key to the research and improvement of those who are still in the industry.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected and reviewed relevant materials through multi-party evaluation and consideration, and have continuously tried and modified the years of R&D experience in this industry to design the shaft structure of such electronic devices. A new type is born.

The secondary purpose of the present invention is that during the rotation of the shaft of the rotating shaft device, the annular portion of the second friction wheel of the friction wheel set can be used to form a right fitting or misalignment state with the concave portion of the first friction wheel, and The elastic member of the damper mechanism is engaged with the convex portion of the second friction wheel to be positioned in the concave portion of the first friction wheel, thereby aligning the main body of the body with the rotating shaft of the rotating shaft device for adjusting the plurality of rotation angles, and the friction wheel The first friction wheel and the second friction wheel of the group are not only easy to process and form, but the plurality of elastic elements of the damping mechanism are general specifications, and the original specifications are not changed or different molds are developed for the purpose, thereby achieving a simple structure. Easy to assemble, easy to mass produce and low cost.

Another purpose of the present invention is that the rotating shaft of the rotating shaft device can be coupled with the friction wheel assembly and the damping mechanism to generate the torsion force, and the compression between the plurality of elastic members can be changed by adjusting the depth of the locking member locked to the screw portion of the rotating shaft. The spacing, in turn, adjusts the amount of torque generated during the rotation of the shaft to assist in slowing the speed at which the body opens or closes.

A further object of the present invention is that the opening of the seat of the rotating shaft device is a limiting groove provided with a blocking surface on both sides, and the abutting portion of the rotating shaft is adjacent to the shaft and extends into the limiting groove. When the main body of the body is rotated by the rotating shaft device as the axis, the blocking position of the rotating shaft of the rotating shaft can be resisted by the resisting block of the rotating shaft to form a blocking position for limiting The predetermined angular range of the main body on the base for the opening or closing action of the rotation makes it difficult for the main body to be related to failure, damage or malfunction due to excessive rotation angle.
