Description

computer shaft

The utility model belongs to the field of computers, in particular to a rotating shaft for portable or notebook computers.

Portable computers, especially the well-known notebook computers, are the mainstream of current communication products. Because of their portability, they break through the traditional limitation that communication processing must be done in the office, and also improve the timeliness of personal communication processing.

Notebook computers are mostly of the so-called clamshell type, that is, the inside of the upper cover is a display screen, which can be opened and closed relative to the keyboard and the main frame, and the connection therebetween is made with what is often called a computer shaft. Therefore, the computer hinge has become a major factor in determining the quality of a notebook computer.

Since the computer rotating shaft is a linking element, it must have the linking function, and the problems of so-called "friction force" and "stagnation" must also be considered. At the same time, it must be wear-resistant, that is, to maintain an appropriate and good friction effect permanently, so that it will not loosen due to repeated operations. In addition, the superiority of computer hinges in terms of appearance, function and user experience is also extremely important, because this is enough to affect consumers' willingness to purchase.

For example, many patents on office computer shafts, some emphasize that the friction torque can be adjusted by themselves, some can eliminate abnormal noise (sharp noise caused by insufficient lubrication), and some emphasize the cooling effect, all of which are computer shafts Give it a new look. However, among the commonly used computer hinges in the market, it is not found that when the display screen of a portable or notebook computer is opened, it can make a crisp ticking sound and produce a positioning effect to increase the user's operating feel. At the same time to meet consumer needs.

The purpose of this utility model is to overcome the defects of the original portable or notebook computers, and provide a computer shaft that not only has the basic functions of general pivoting and frictional torque, but also when the display screen is flipped and closed. The rotating shaft can make a crisp ticking sound and at the same time produce a "computer rotating shaft" with a positioning effect.

The technical scheme of the utility model is: a shaft, one end of which has several rod holes for locking and connecting with the computer, a larger-sized collar is arranged near the central section, and a shaft column is extended transversely at the other end. The two opposite ends are processed to form two planes and two arc-shaped curved surfaces, and a column pattern is set at the rear end of the pole;

A frame piece is a ring with a circular ring hole whose size corresponds to the shaft column and allows the shaft column to pass through, and a wing extends above it, and has several wing holes for locking and connecting with the computer. The periphery of the ring is provided with two one or more lamellae;

A shaft cylinder, which is a hollow cylinder chamber, a circular cylinder hole for the shaft column to pass through is also provided at the corresponding annular hole, and an embedded hole for engagement is provided at the corresponding piece protrusion. The rear bottom of the shaft cylinder The end is provided with ring-shaped barrel teeth;

One or more sets of elastic friction elements are composed of two disc-shaped shrapnels arranged opposite to each other, and corresponding to the cylinder holes, holes for the shaft to pass through are respectively arranged, and the disc-shaped shrapnel are accommodated in the cylinder chamber;

A spacer, which is a cylindrical fixture, is provided with a through hole for the pole to pass through on the cross-section side corresponding to the pole;

A fixed elastic piece is a shaft hole opened by a shaft piece with the same shape as the through hole for the shaft column to pass through, and a reed piece extends transversely in the direction corresponding to the barrel teeth, and keeps in contact with the barrel teeth;

A nut, on the shaft, there is a nut that fits with the column thread, tightens each component and adjusts the friction torque;

The sheet ring of the frame sheet also has to be provided with embedded holes, and the corresponding part of the shaft cylinder is protrudingly provided with sheet protrusions.

Through the specific implementation of the utility model, in addition to making the computer shaft have the original friction torque and adjustment functions, it can also be locked and connected with the computer host and the display screen separately. It can make each cylinder tooth touch the leaf spring, and make a crisp sound and produce the effect of stagnant positioning, which is actually a function that cannot be obtained by the computer shaft commonly used in the office.

Below in conjunction with accompanying drawing, the technical scheme of the utility model is further described:

As shown in the figure, basically, the computer shaft of the utility model is mainly composed of a shaft 1, a frame 2, a shaft tube 3, one or more groups of elastic friction elements 4, a pad 5, a fixed The shrapnel 6 and a nut 7 are combined.

Wherein, the shaft rod 1 is a rod-shaped object, and several rod holes 11 are arranged on one side thereof for locking the host computer or the display screen of the computer, and a larger rod ring 12 is arranged near the middle section of the shaft rod 1 , for offsetting with the frame piece 2 described later; in addition, the other side of the rod ring 12 then extends a rod column 13 transversely, and its arbitrary two opposite ends are then turned to form two flat surfaces 131 and two arc-shaped curved surfaces 132, And the rear end of the post 13 is provided with a column thread 133 for threaded connection with the nut 7 described later.

The frame piece 2 is formed by stamping and bending a metal sheet. It is mainly made of a circular ring hole 211 with a size corresponding to the diameter of the two curved surfaces 132 in the center of a piece of ring 21, and the rod 13 is fitted, and the piece of ring A piece of wing 22 extends above 21, and there are several wing holes 221 on it, for locking the main frame or display screen of the computer. And in order to make the frame piece 2 form an interlocking relationship with the shaft tube 3 described later, two or more piece protrusions 212 are punched out on the periphery of the ring 21 for engagement with the shaft tube 3 .

The shaft cylinder 3 is a hollow cylinder and forms a hollow cylinder chamber 31. A circular cylinder hole 32 is also provided at the corresponding annular hole 211, and an embedded hole 33 is opened corresponding to each piece protrusion 212. , the tab protrusion 212 and the embedded hole 33 are engaged with each other to form a linkage.
