【技术领域】【Technical field】
本发明是有关于一种光碟机装置,且特别是有关于一种具有减低噪音功效的光碟机装置。The present invention relates to an optical disc drive device, and more particularly to an optical disc drive device with the function of reducing noise.
【背景技术】【Background technique】
光碟机装置为现在电脑非常重要的周边装置之一。不管是DVD、CD-ROM或是CD-R/W都是电脑不可或缺的光碟机装置,用来读取光碟储存媒体的数据或写入数据到光碟储存媒体上。The optical disc drive device is one of the very important peripheral devices of the computer now. Whether it is DVD, CD-ROM or CD-R/W, they are all indispensable optical disc drive devices for computers, which are used to read data from optical disc storage media or write data to optical disc storage media.
习知的桌上型电脑所使用的光碟机装置通常有碟片夹持器的设计。当光碟机的承载座上承载一光碟储存媒体时,碟片夹持器与承载座藉磁力的吸引将光碟储存媒体夹持于两者中间。接着,承载座会被光碟机装置里的主轴马达驱动而旋转,碟片夹持器、承载座以及夹持于两者中间的光碟储存媒体同步旋转,使得读写头可以读取数据或写入数据到光碟储存媒体。Conventional optical disc drives used in desktop computers usually have a disc holder design. When an optical disc storage medium is carried on the bearing base of the optical disc drive, the disc holder and the bearing base clamp the optical disc storage medium between them by magnetic attraction. Then, the carrier will be rotated by the spindle motor in the optical disc drive device, and the disc holder, the carrier and the optical disc storage medium clamped between them will rotate synchronously, so that the read-write head can read data or write Data to CD storage media.
然而,当光碟机装置入仓(托盘缩回光碟机内的动作)时,承载座会有一个上升与碟片夹持器接合的动作。因为磁力的吸引,接合的瞬间,碟片夹持器会快速的撞击承载座而产生撞击的噪音。上述动作所产生的噪音量大小,尤以当光碟机装置未放入光碟时之入仓动作为最大。在现今环保意识抬头的状况下,此问题更需特别重视及处理。However, when the optical disc drive is put into the bin (the action of retracting the tray into the optical disc drive), the supporting base will have an action of rising to engage with the disc holder. Due to the magnetic attraction, the disc holder will quickly hit the carrier seat at the moment of engagement, resulting in a crashing noise. The amount of noise generated by the above-mentioned actions is the largest especially when the optical disc drive device is not loaded with a disc. In today's environment where environmental protection awareness is on the rise, this issue needs to be paid more attention to and dealt with.
【发明内容】【Content of invention】
因此本发明的目的就是在提供一种具有减低噪音功效的光碟机装置。Therefore, the object of the present invention is to provide an optical disc drive device with the effect of reducing noise.
根据本发明之上述目的,提出一种具有减低机件碰撞噪音功效的光碟机装置,用来读取一光碟储存媒体。此光碟机装置包含承载座、机壳及碟片夹持器。承载座系用以放置光碟储存媒体。机壳上的凹槽处设置一破孔。碟片夹持器设置于破孔,且承载座于上升时系与碟片夹持器接触,承载座从接触位置下降时系与碟片夹持器分离。碟片夹持器更包含基座及弹性悬臂。至少一凹陷区位于基座上,且凹陷区与承载座相面对。至少一弹性悬臂连结于基座,且弹性悬臂之一端具有一凸点。弹性悬臂上之凸点与承载座相面对且凸点位于凹陷区与承载座之间。According to the above-mentioned purpose of the present invention, a kind of optical disc drive device with the effect of reducing the impact noise of mechanical parts is proposed, which is used for reading an optical disc storage medium. The optical disc drive device includes a bearing base, a casing and a disc holder. The bearing seat is used for placing the optical disc storage medium. A hole is arranged at the groove on the casing. The disc holder is arranged in the hole, and the bearing seat is in contact with the disc holder when it rises, and is separated from the disc holder when the bearing base descends from the contact position. The disc holder further includes a base and an elastic cantilever. At least one recessed area is located on the base, and the recessed area faces the bearing seat. At least one elastic cantilever is connected to the base, and one end of the elastic cantilever has a convex point. The convex point on the elastic cantilever faces the bearing seat and the convex point is located between the recessed area and the bearing seat.
上述基座更包含第一对吸部,且凹陷区位于第一对吸部与凸点之间。上述承载座更包含第二对吸部,当光碟储存媒体入仓时,承载座上升,第一对吸部与第二对吸部相互磁力吸引。若第一对吸部的材料为铁、钴、镍或上述金属的合金,第二对吸部的材料可为磁铁。若第一对吸部的材料为磁铁,第二对吸部的材料可为铁、钴、镍或上述金属的合金。或者,第一对吸部及第二对吸部的材料皆为磁铁。The above-mentioned base further includes a first pair of suction parts, and the recessed area is located between the first pair of suction parts and the bump. The bearing base further includes a second pair of suction parts. When the optical disc storage medium is put into the bin, the bearing base rises, and the first pair of suction parts and the second pair of suction parts attract each other magnetically.

【具体实施方式】【Detailed ways】
如上所述,本发明提供一具有减少噪音功效的光碟机装置,藉由设计一能提供缓冲结构的碟片夹持器。当光碟机装置的承载座与碟片夹持器接合的瞬间,碟片夹持器的缓冲结构可减缓因两者磁力相吸所产生的急速碰撞,进而减少急速接合(之撞击)所产生之噪音。以下将藉较佳实施例说明本发明的细节。As mentioned above, the present invention provides an optical disc drive device with the effect of reducing noise by designing a disc holder capable of providing a buffer structure. When the bearing seat of the optical disc drive device is engaged with the disc holder, the buffer structure of the disc holder can slow down the rapid collision caused by the magnetic attraction between the two, thereby reducing the impact caused by the rapid engagement (impact). noise. The details of the present invention will be described below with preferred embodiments.
请参照图1及图2,其绘示依照本发明一较佳实施例的一种碟片夹持器的结构图。此图示绘示碟片夹持器110与承载座接合的一面之结构设计。在碟片夹持器之基座112上接近中心的部份,设计三个弹性悬臂114a/114b/114c作为缓冲结构。当三个弹性悬臂114a/114b/114c与承载座130接触时,会往三个凹陷区112a/112b/112c内弯折变形。当两者不接触时,三个弹性悬臂114a/114b/114c会恢复到原来的位置。Please refer to FIG. 1 and FIG. 2 , which illustrate a structural view of a disc holder according to a preferred embodiment of the present invention. This figure shows the structural design of the side of the
因此,碟片夹持器110于弹性悬臂部分材料的选择需要具有弹性且耐疲劳破坏的特性,使三个弹性悬臂114a/114b/114c能够接受多次的接合撞击后,能具有缓冲急速接合的能力。Therefore, the selection of materials for the elastic cantilever part of the
此外,三个弹性悬臂114a/114b/114c其中一端与基座112连接,另一悬空端具有凸点116a/116b/116c,使承载座与碟片夹持器接合处为凸点116a/116b/116c的顶端。凸点116a/116b/116c较佳形状为半圆球结构,使原本由冲力造成整个平面撞击声音(因整个平面造成的鼓效应,使声因有放大的效果),因三点接触的原因可以有效的降低。In addition, one end of the three
尽管上述较佳实施例使用三个弹性悬臂,其他数量的弹性悬臂亦可产生降低噪音的功效。Although the above-mentioned preferred embodiment uses three elastic cantilevers, other numbers of elastic cantilevers can also have the effect of reducing noise.
请参照图2,其绘示依照本发明一较佳实施例的一种光碟机装置(未放光碟储存媒体状态)的剖面图。碟片夹持器110位于光碟机100的机壳102之凹槽104的破孔102a内。当承载座130未与碟片夹持器110接合时(两者分离),碟片夹持器110的边缘靠在破孔102a周围的机壳102上(此状态并未绘示于图面)。当承载座130与碟片夹持器110接合时(如图2所示,两者接触),承载座130之第二对吸部132与凸点116a接触,使得弹性悬臂114a向凹陷区112a弯曲变形。因此,在此状态下,凸点116a位于凹陷区112a与承载座130之间。凹陷区112a位于第一对吸部118与凸点116a之间。因为第一对吸部118及第二对吸部132两者磁力的互相吸引,使承载座130与碟片夹持器110接合并夹持光碟储存媒体。Please refer to FIG. 2 , which shows a cross-sectional view of an optical disc drive device (with no optical disc storage medium) according to a preferred embodiment of the present invention. The
图2系绘示光碟机未放光碟储存媒体状态,其夹持间隙约为0.8mm。上述第一对吸部118的材料若为铁、钴、镍或上述金属的合金,则第二对吸部132的材料可为磁铁,使得第一对吸部118及第二对吸部132能相互吸引。若上述第一对吸部118的材料若为磁铁,则第二对吸部132的材料可为铁、钴、镍或上述金属的合金,使得第一对吸部118及第二对吸部132能相互吸引。或者,第二对吸部132及第一对吸部118的材料皆为磁铁,则两者必能相互吸引。Figure 2 shows the state of the optical disc drive without an optical disc storage medium, and the clamping gap is about 0.8 mm. If the material of the above-mentioned first pair of
请参照图3,其绘示依照本发明另一较佳实施例的一种光碟机装置(光碟储存媒体的厚度为0.85mm状态)的剖面图。当光碟储存媒体120(例如厚度为0.85mm)被承载座130与碟片夹持器110夹持于中间时,主轴马达140驱动碟片夹持器110、承载座130以及夹持于两者中间的光碟储存媒体120旋转,使得读写头可以读取数据或写入数据到光碟储存媒体。Please refer to FIG. 3 , which shows a cross-sectional view of an optical disc drive device (the thickness of the optical disc storage medium is 0.85mm) according to another preferred embodiment of the present invention. When the optical disc storage medium 120 (for example, the thickness is 0.85mm) is clamped between the bearing
请参照图4,其绘示依照本发明又一较佳实施例的一种光碟机装置(光碟储存媒体的厚度为1.2mm状态)的剖面图。此较佳实施例与上述较佳实施例不同之处在于,光碟机装置100读取较厚的光碟储存媒体120(厚度为1.2mm)。由上述的三个较佳实施例可知,具有弹性悬臂设计的碟片夹持器可适应各种厚度的光碟储存媒体及无光碟储存媒体的状态,且均能减少承载座与碟片夹持器急速接合的瞬间所产生之噪音。经试验的证实,上述较佳实施例的设计可减低噪音量多达5.87db。Please refer to FIG. 4 , which shows a cross-sectional view of an optical disc drive device (the thickness of the optical disc storage medium is 1.2mm) according to another preferred embodiment of the present invention. The difference between this preferred embodiment and the above-mentioned preferred embodiment is that the optical
由上述本发明较佳实施例可知,应用本发明之具有减少噪音功效的光碟机装置,其具有弹性悬臂设计的碟片夹持器,能缓冲承载座与碟片夹持器的急速接合,消除平面撞击所产生的鼓效应,而达成噪音减低的功效。It can be known from the above-mentioned preferred embodiments of the present invention that the optical disc drive device with noise reduction effect of the present invention has a disc holder designed with an elastic cantilever, which can buffer the rapid engagement of the bearing seat and the disc holder, eliminating The drum effect produced by plane impact achieves the effect of noise reduction.
虽然本发明已以一较佳实施例揭露如上,然其并非用以限定本发明,任何熟习此技艺者,在不脱离本发明之精神和范围内,当可作各种之更动与润饰,因此本发明之保护范围当视后附之申请专利范围所界定者为准。Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in this art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the scope of the appended patent application.
