Abstract

The utility model relates to a device, which achieves earthquake resistance for high speed CD drive operation and is designed according to the conservation law of angular momentum in fixed-point motion kinematics and gyroscope experimental model. The key part comprises three rotation shafts and a CD tray with the same working principle of the gimbal mount gyroscopic inertia. Therefore, when the transmission shaft of the device is rotated with high speed, the three shafts keep mutual perpendicular; the CD tray is not subjected to moment action no matter the CD driver is in translation or rotation, which achieves stable effect. At the same time, system can return to a stable status through self-regulation if working circumstance is changed.

Description

A kind of device that reduces the CD vibrations

Technical field

The utility model relates to a kind of device that reaches the antidetonation purpose in the CD-ROM drive high-speed cruising.

Background technology

At present, people are in order to solve the problem of in CD-ROM drive high-speed cruising CD vibrations, and the unit of plastic of placing white between the fixed screw at top and movement and the rubber air mattresses of adopting as the damping, buffering material more.There are some CD-ROM drive manufacturers to adopt the method for one group of ball bearing of configuration under CD ROM support tray, when vibrations appear in CD, steel ball can be gone to lighter weight under action of centrifugal force part plays equilibrium activity, turn round under horizontality thereby remain CD, thereby reduce vibrations and reduce noise.The vibrations that produce when also useful 2 anti-vibration devices and dynamic damper absorb the spindle motor high speed rotating effectively simultaneously make CD-ROM drive noise reduction in the running.

In the present existing patent " Chinese utility model patent " to authorize publication number be that " storage medium shock preventing system set " and the CN1453789 patented technologies such as " vibration suppressing mechanisms of CD-ROM drive " of CN1492442 also can reach to a certain extent and reduces the purpose that CD shakes, but these technology have complex structure, and existing equipment is changed shortcomings such as bigger.

Summary of the invention

This device is according to the fixed point rotational motion law of conservation of angular momentum, designs in conjunction with the gyroscope empirical model.Its core is three turning axles and optical disc tray.Its principle of work is with the gyroscopic gyroscopic inertia of gimbal.Thus, three axles keep vertical mutually during this device transmission shaft high speed rotating, no matter CD-ROM drive translation or rotation, and CD holder can not be subjected to moment loading, thereby plays stable effect.When working environment changed, system can oneself's adjustment reach steady state (SS) simultaneously.

The technical scheme that its technical matters that solves the utility model adopts is: circular housings is rotated with CD, be similar to the high speed rotor in the gyro, the stable state that had both kept total system, the relative static conditions of CD and carriage is provided again, avoid CD cut to occur, prolong CD serviceable life, make speed and the quality reading to coil all obtain bigger lifting.Joint spider is connected CD holder and driving shaft with connector, it is vertical that joint spider remains diaxon, and connector couples together joint spider and driving shaft, and keeps three axles vertical in twos in the carriage turns process.By the combination of member,, make CD in rotation process, not be subjected to the effect of moment of face for CD provides three orthogonal degree of freedom.

The beneficial effects of the utility model are that this device is applied to optomagnetic field of storage, to strengthen reading and writing data ability under the vibration environment, avoids head wear, life-saving.The characteristics that this system is the most outstanding are that it under the high-speed cruising condition that heals, reaches the stable effect that heals.The gyroscopic theory of maturation is applied to the CD-ROM drive damping, makes system reach stable.Vibrations are converted into rotation.Change less to existing equipment.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 2 is the longitudinal profile structural map of Fig. 1.

Fig. 3 is the transverse section structural map of Fig. 1.

Fig. 4 is a schematic perspective view of the present utility model.

1 is circular housings in the accompanying drawing, the 2nd, and connector (lower cover), the 3rd, joint spider, the 4th, connector (loam cake).

Embodiment

Circular housings in synoptic diagram shown in the accompanying drawing (1) both sides aperture matches with joint spider (3) two major axis, connector (lower cover) (2) matches with connector (loam cake) (4), then two minor axises of joint spider (3) respectively and connector (lower cover) (2) cooperate with the circular hole at connector (loam cake) (4) center, connector (lower cover) (2) lower end links to each other with CD-ROM drive motor.

CD is placed on circular housings (1), and fixing.The CD-ROM drive motor that links to each other with connector (lower cover) (2) lower end drives connector (lower cover) (2) and rotates with connector (loam cake) (4), keep three axles vertical in twos in the carriage turns process, for CD provides three orthogonal degree of freedom, make CD in rotation process, not be subjected to the effect of moment of face.
