Abstract
The invention relates to an anti-vibration system, in particular to a suspended type anti-vibration system used in electronic products such as a CD-ROM drive, a hard disk, an electronic circuit board, etc. The anti-vibration system comprises at least three buffer cells and a plurality of limit parts; the buffer cell comprises a hollow elastic part, a connecting part which is fixedly connected to the upper end face of the elastic part; when in use, the buffer cells are arranged to be a polygon, the connecting part in each buffer cell is fixedly connected with the lower end face of a part needing vibration damping, and all the limit parts are connected to the top face or side of the part needing vibration damping. The suspended type anti-vibration system can isolate the part needing vibration damping from a vibration source, thus preventing the part needing vibration damping from being affected by vibration directly; furthermore, the suspended type anti-vibration system has the advantage of withstanding large longitudinal and transverse continuous vibration shock.
Description
Technical field
Various embodiment of the present invention relates generally to a kind of anti-shock system, particularly a kind of suspended type shockproof system that is used for as electronic products such as CD drive, hard disk, electronic circuit boards.
Background technique
Common vibrations divide two kinds of vertical and horizontal, and high-frequency vibrations are for producing a very large impact in the performance and the working life of the hard disk in the in running order electronic product, CD-ROM drive etc.For example at CD driver, shaven head is fixed on the machine case structure, and CD is fixed on the main shaft of rotation.Because main shaft separates fully with shaven head, when CD-ROM drive was worked, this structure can not be born any vibrations fully.Because if in a single day vibrations take place, the vibrations of CD are asynchronous with the machine box, cause shaven head to depart from disc tracks, the shaven head of having to reorientate repeatedly, and read-write makes repeated attempts.So not only read or write speed reduces greatly, also can cause the life-span of shaven head to shorten greatly.And because read-write mistake repeatedly, a lot of shaven heads can strengthen working power automatically, thereby have further shortened the bare headed life-span.
Between the problems referred to above, in order to reduce the vibrations that electronic products such as CD-ROM drive are subjected to, a kind of anti-shock system that is used for vehicle-mounted CD-ROM drive has appearred at present.As shown in Figure 4, this anti-shock system comprises rigid support 113 and buffering supported spring 112, and rigid support is fixed in the middle part of CD ROM support tray 111, and the buffering supported spring is connected on the CD ROM support tray.During use, the shaven head of vehicle-mounted CD-ROM drive and the main shaft that rotates all are fixed on the pallet.Though this anti-shock system is synchronous rotating spindle and bare headed vibrations, but be connected with the machine box because pallet is whole, and have being rigidly connected of rigid support between pallet and the machine box, so the vibrations of machine box outside still can be directly coupled to pallet by rigid support.When vibrations were excessive, because CD and main shaft do not rigidly fix, the vibrations of CD still can be asynchronous with shaven head.So this design still can not be satisfied the strong special applications of some vibrations, for example, in audio amplifier when work, produce in strong, that continue, the irregular vibrations, particularly subwoofer, vibration amplitude and acceleration are all very big, and existing shockproof CD-ROM drive all can not bear this job requirement.
Summary of the invention
At above-mentioned technical problem, the purpose of this invention is to provide a kind of suspended type shockproof system, it can make required shockproof parts and vibratory source isolate, and the influence of avoiding required shockproof parts directly to be given a shock has and bears higher vertical and laterally lasting jerk advantage.
The object of the present invention is achieved like this: comprise at least three buffer cells, and several limit position parts, described buffer cell comprise inner for hollow elastic member, be fixedly connected on the connected element of elastic member upper-end surface, during use, a plurality of buffer cells are arranged and are a polygonal, connected element in each buffer cell is fixedlyed connected with the lower end surface of required shockproof parts, and each limit position part is connected in required shockproof parts end face or side.
Described buffer cell also comprises the supported spring that entangles elastic member, and this supported spring upper end is between the upper-end surface of the upper-end surface of elastic member and connected element.
Elastic member in the described buffer cell is tapered elastic member, and supported spring is tapered supported spring.
Elastic member in the described buffer cell is hollow silicone rubber seal cover.
Described each buffer cell lower end is provided with the connection base.
Described limit position part comprises elastic member and connected element, and connected element one end is fixedly connected on the axial end of elastic member miner diameter end, and the connected element the other end is fixedlyed connected with required shockproof parts.
Described elastic member is hollow silicone rubber seal cover, and elastic member is tapered.
Described limit position part comprises and also comprises the supported spring that is used to be enclosed within the elastic member excircle.
Described limit position part is spacing supported spring.
Adopted such scheme, because buffer cell is isolated required shockproof parts with the parts that directly are given a shock coupling, and because the elastic member of buffer cell is hollow, elastic member by buffer cell can produce nonlinear reaction balance power to external pressure, can reduce the vibrations that required shockproof parts are subjected to.A plurality of buffer cells are arranged and are a polygonal, are beneficial to and make the vibrations homogenization.By the cross spacing of limit position part, can prevent that not only required shockproof parts lateral displacement from crossing the structure of holocaust buffer cell to required shockproof parts; Simultaneously also can provide cushion effect to required shockproof parts.Suspended type shockproof system of the present invention is not only simple in structure, and cost is low; And can reach the instantaneous jerk of 50g and the lasting jerk that can bear vertical 1.5g and horizontal 3g.
Described buffer cell also comprises the supported spring that entangles elastic member, and this supported spring upper end is between the upper-end surface of the upper-end surface of elastic member and connected element.When being subjected to than big bang, supported spring not only can provide buffering, reduces the impact force that elastic member is subjected to.And the reaction force that supported spring produces is linear within the specific limits, and the elasticity coefficient of reasonably arrange in pairs or groups supported spring and elastic member can be adapted to various required shockproof parts.
The invention will be further described below in conjunction with the drawings and specific embodiments.
