Description

Due to the development of material science, electronic components are becoming thinner, thinner and smaller, and thus portable computers are flourishing. For now, the notebook computer is very popular, and the reason for exploring it is that it is easy to carry and has high mobility.

The notebook computer that continues to be used is a two-piece cover type, that is, one piece is a display screen, and the other piece is a keyboard and related electronic components, and the two pieces are connected by a hinge for opening or closing.

Anyone who has used a notebook computer knows that when the opening and closing control is performed, the operation is often affected. If the shaft is too loose, when the display screen is opened, it will often be automatically and slowly closed during operation, and if it is too tight, it will be opened. It is not easy to close, and there are often abnormal sounds. Therefore, in recent years, the industry has also begun to pay attention to the research and development of the rotating shaft.

In fact, from the perspective of the positioning of the upper cover, the required torque varies with the viewing angle and position. For example, when the cover is closed, the required torque is very small, and when it is opened in a vertical state, The required torque is also very small, and between horizontal and vertical, the required torque varies with the angle. However, according to the design still in use at present, it does not take into account the change of the torsion force, which causes the strength of the friction force of each component to be different, and the service life is also different.

In view of this, based on years of experience in the production and sales of computer shafts, the applicant developed the "computer shaft" in this case based on the follow-up research on the patent 81203611 authorized by the Chinese Patent Office.

The purpose of this utility model is to provide an improved computer shaft, which can overcome the above-mentioned shortcomings of the conventional computer shaft, and its torque can change with the angle, thereby improving its performance and life.

According to the computer rotating shaft of the utility model, it comprises a mandrel, a set of shafts, a spring and a new type of computer rotating shaft of a latch; wherein, one end of the mandrel is a flat shaft piece, and more than two shaft holes are provided for connecting with the The computer is locked, and the other end is a hollow rod-shaped shaft, which is respectively opened with a transverse shaft groove, and an embedded hole is opened at the front edge of the shaft groove, and a hollow sleeve is integrally extended from the other end, and is in the There is a semi-circular sleeve groove on one side, which is formed when the spring is inserted into the shaft hole, then inserted into the sleeve and passed through the embedded hole by a bolt.

In order to further reveal the specific technical content of this case, first please refer to the illustrations, wherein Figure 1 is a three-dimensional exploded view of this case, and Figure 2 is a schematic cross-sectional view of this case after assembly.

Fig. 1 is the three-dimensional exploded view of the computer rotating shaft of the present utility model;

FIG. 2 is a cross-sectional view of the assembled computer shaft of the present invention.

As shown in the figure, basically, this case is made up of a mandrel 1, a set of shaft 2, a spring 3 and a latch 4.

Wherein, mandrel 1 is a strip thing, and its one end is flat axle piece 11, and has more than two axle holes 12 on it, for when combining with computer, borrow the usefulness of screw and computer locking. And the other end then integrally extends a hollow rod-shaped shaft 13, and forms a rod hole 14, and wherein then has a shaft groove 15 respectively on the shaft rod, thereby can make the rod hole 14 of shaft rod 13 rely on the effect of shaft groove 15 And it can be stretched outward elastically, and then there is an embedding hole 16 at the front edge of the shaft groove 15 for the fitting and positioning of the latch 4 . Between the shaft piece 11 and the shaft rod 13 is a center ring 17 with a larger outer diameter, and the whole mandrel 1 is integrally arranged.

Sleeve shaft 2 it also is a strip body, and one end of its outside is also the same as the sleeve sheet 21 of aforementioned shaft sheet 11, and also has more than two sleeve holes 22 on it, for the usefulness of locking when combining with the computer, and At the other end, a hollow sleeve 23 is provided, and at one end of the sleeve 23, there is a semicircular sleeve groove 24, wherein the sleeve groove 24 can be used as the aforementioned mandrel 1 after being inserted into the sleeve 23, and by means of the latch 4 After being inserted into the embedding hole 16 , a turning limit can be formed in the sleeve groove 24 , and the entire sleeve shaft 2 is also integrated with the mandrel 1 .

The spring 3 is a commonly used spring, and its outer diameter is slightly larger than the rod hole 14, so that after being inserted into the rod hole 14, the shaft 13 can be radially stretched elastically because the shaft 13 has a shaft groove 15.

The pin 4 is a long cylinder, and its function is that the mandrel 1 and the sleeve shaft 2 are inserted into the embedded hole 16 after being inter-embedded, and the height of the plug 4 is higher than the embedded hole 16. It can prevent the mandrel 1 and sleeve shaft 2 from falling off.

Please refer to the diagram again. When assembling, first insert the spring 3 into the rod hole 14. Since the outer diameter of the spring 3 is larger than the rod hole 14, and the shaft 13 is provided with a shaft groove 15, due to the effect of the spring 3, The outer diameter of the shaft 13 can be relatively expanded, and at the same time the sleeve 23 and the shaft 13 are fitted together. Since the inner diameter of the sleeve 23 is smaller than the outer diameter of the shaft 13 at this time, the mandrel 1 and the sleeve 2 can be borrowed. The elastic action of the spring 3 and the shaft 13 generates frictional force. At this time, the pin 4 is inserted into the embedded hole 16, so the swing range of the pin 4 is controlled by the groove 24, which can form the starting point and the final angle of the swing. , and prevent the mandrel 1 and sleeve shaft 2 from falling off each other.

Therefore, when rotating, because the rod hole 14 is embedded by the spring 3, the shaft rod 13 is in an expanded state, but it is also limited by the inner diameter of the sleeve 23, so it has friction, and when the computer cover is lifted, it can be opened. position.

Moreover, when the spring 3 is actually implemented, it can also be replaced by an elastic material such as a sleeve, a spring pin, or rubber according to the required friction force, so that the shaft rod 13 can also have the function of pressing and torsion. If the required torsion is small, the spring 3 can also be discarded, and the expansion effect when the sleeve 23 is connected with the shaft rod 13 can be directly used to obtain sufficient friction and provide a small torsion value.

What is shown in this case is a kind of preferred embodiment, and all partial changes or modifications originating from the technical idea of this case and easily deduced by people familiar with this technology are all within the scope of patent rights of this case.

To sum up, the utility model in this case shows that it is different from the prior art features in terms of purpose, means and efficacy, it is creative and practical, and it also conforms to the novelty.
