Embodiment
Basic design of the present utility model is to realize the effect of the disappear crack and the vibration damping of both direction (directions X and Y direction) simultaneously with a kind of mechanism, thereby simplify movement and complete machine structure and improve both functional reliabilities.
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
Referring to Fig. 1, be that example is illustrated with one group of damping column that comprises two hollow semi-round ring shape structures.The two-way crack damper mechanism that disappears of movement is cooperated by the damping column on vibration damping inclined-plane on the pallet 1 11,12 and the mainframe 2 21,22 to be finished, wherein: in opposite directions vibration damping inclined-plane 11 of She Zhiing and vibration damping inclined-plane 12 respectively with pallet 1 direction of motion oblique, and perpendicular to the principal plane (being the XY plane) of pallet 1; Damping column 21 and damping column 22 are the elasticity post, are preferably hollow semi-round ring shape structure, and it is provided with the vibration damping cylinder in opposite directions a side respectively.Like this, thus pallet 1 arrives video disc when reading and writing ready position vibration damping cylinder and the contact of corresponding vibration damping inclined-plane and mutually extruding make damping column 21 and damping column 22 distortion back generation elastic force.Particularly, each parts is arranged by following requirement:
Referring to Fig. 2～Fig. 4, vibration damping inclined- plane 11,12 lays respectively at the end of pallet 1, wherein: the position when damping column 21 contacted with vibration damping inclined-plane 12 with vibration damping inclined-plane 11, damping column 22 when size L1 shown in Figure 3 was the CD normal play, this moment, damping column 21,22 was out of shape.After damping column 21,22 distortion, produce the elastic force of contact cylinder normal orientation, the component that it is decomposed into directions X and Y direction makes pallet 1 realize disappearing crack and vibration damping simultaneously on this both direction.Referring to Fig. 5～Fig. 7, damping column 21,22 lays respectively at the end of mainframe 2, and wherein: damping column 21,22 one-piece constructions are hollow semi-round ring shape structure, and its vibration damping cylinder is respectively line with the way of contact on pallet vibration damping inclined- plane 11,12 and contacts; Normal size when as shown in Figure 7, elastic deformation does not take place damping column 21,22 is L2.For reaching the purpose of the crack vibration damping that disappears, elastic deformation must take place in damping column 21,22, need guarantee size L2 greater than size L1 when therefore designing, and in other words, the decrement of damping column 21,22 is the value that size L2 deducts L1.The utility model adopts hollow semi-round ring shape structure, can control the decrement of damping column 21,22 well, thereby produce suitable elastic force, guarantees thus the pallet 1 crack vibration damping that reliably disappears.Referring to Fig. 8, because of damping column 21,22 is a symmetrical structure, so analyze: when damping column 21,22 arrives the decrement of design, vibration damping inclined- plane 11,12 is produced directed force F with one of them; This directed force F is decomposed into the FX of directions X and the FY of Y direction, has guaranteed that pallet 1 does not shake at directions X and Y direction, can eliminate the gap between pallet 1 and the mainframe 2.Like this, even the centrifugal force that the optical disk high-speed rotation produces is delivered to pallet 1, this moment, pallet 1 also can can't vibrate freely because of being fixed, and vibration does not just have mechanicalness noise, and is more steadily reliable when this makes movement work naturally.
It should be noted that the utility model can be provided with many group damping columns.In addition, every group of damping column also can only comprise a damping column, at this moment as long as in its both sides a described vibration damping cylinder is set respectively, do not repeat them here.
The vibration damping purpose is realized in the above-mentioned movement gap that the crack damper mechanism is eliminated both direction simultaneously with a kind of structure that disappears.Obviously, the disappear mode in crack of this vibration damping is equally applicable to not repeat them here in the common mechanism.
In sum, characteristics of the present utility model are that two vibration damping inclined-planes are set on pallet in opposite directions, simultaneously at least one group of damping column of mainframe relative set.During writable disc, each damping column contacts with the vibration damping inclined-plane and pushes the back distortion and produce elastic force, and this elastic force can be decomposed into the component of directions X and Y direction, thereby makes pallet realize disappearing crack and vibration damping simultaneously on this both direction, and the assurance movement is steadily worked reliably.Thus, the utility model with a kind of mechanism just can be simultaneously to the pallet both direction crack vibration damping that disappears, compare traditional structure: its structural complexity reduces, and helps to simplify the structure of movement; Because parts reduce, the out of order probability of movement lowers, thereby has improved the reliability of movement.
The utility model CD player, its movement uses the above-mentioned crack damper mechanism that disappears, and other parts use prior art to get final product, and do not repeat them here.This CD player, the vibrating noise of the relative mainframe of pallet is little, and stable working is reliable.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
