Background technique
Computer is the precision machinery that has held disk set in inside, also must be noted that when using not only in carrying, and on desk not apply excessive impact.Especially portable computer uses owing to changing the field of employment, so situation about being reapposed on the desk is more.Moving to the somewhere and using under the situation of portable computer, the user is placed on an end of computer on the desk usually, slowly the other end is stopped at computer on the desk near desk then.At this moment, before computer integral body will stop at above the desk fully, the user can leave computer with hand sometimes, caused disk set to be subjected to stronger impact.This phenomenon that falls is referred to as in this manual, falls.
In addition, make the bottom surface of computer smooth fully,, and have also crooked a little situation above the desk of placing computer so leave crookedly slightly owing on cost, be difficult to accomplish.In this case, produce the gap, and cause the user when operation keyboard, to produce less activity and it is felt bad in the part of computer bottom surface with between above the desk.Should activity be referred to as in this manual to shake.
A kind of rubber feet is disclosed in patent documentation 1 (Japanese kokai publication hei 9-172478 communique), this rubber feet is provided with projection at front end, projection is absorbed leg by the crushing of lighter load shakes, and selects the hardness as the rubber of material after crushing in order to increase sharply counter-force.Disclose in the patent documentation 2 (Japan opens flat 3-105737 communique in fact) and on base plate, be provided with a plurality of projections, and in each projection, formed the vibrationproof cushion pad in hole.Patent documentation 3 (Japan opens clear 63-187746 communique in fact) discloses in the behind of the 1st elastic caoutchouc that constitutes protuberance the space has been set, and the vibration-proof rubber parts of the 2nd elastic caoutchouc are set behind at it again.
On the matrix bottom surface of the portable computer that forms with synthetic resin or metal sheet, the elastic support member that is referred to as rubber feet is installed generally.The rubber feet that is used for portable computer needs function that absorption is applied to the impact on the disk set because of tilting, falling, prevent the function of shaking and the function of stable support when using a computer on desk.Have again, change the position of portable computer owing to the user frequently makes the bottom surface slide on desk, so elastic support member needs wearability.The shape that elastic support member is made smooth cuboid also only realizes simultaneously that with the selection of material these functions are comparison difficulties.
For example, in order to prevent to shake, need do the area of elastic support member little as far as possible.But if area diminishes, then wearability and intensity can go wrong.Have again,, then can't give full play to absorptivity the impact of tilting, falling if select hard material in order to keep wearability and intensity when reducing area.Have again, in order to prevent to shake, need absorb the stroke be equivalent to computer bottom surface and the tolerance clearance amount above the desk by elastic support member, only with the selection of material satisfy about tilt, fall, shake, all functions of stability when using and wearability become more and more difficulty.Realize under above-mentioned all multi-functional situations making shape have feature,, then can't make the structure of the e-machine of various load of reply and service condition if do not make the structure of the adjustment of being convenient to carry out the parameter relevant with elastic force.In addition, from the viewpoint of manufacture cost, wish that elastic support member is with the integrated structure of homogenous material.
Summary of the invention
So, the object of the present invention is to provide a kind of can shake simultaneously prevent and because of tilting, fall the elastic support member of the absorption of the impact that causes.Have again, the purpose of this invention is to provide the superior elastic support member of a kind of wearability.Have again, the purpose of this invention is to provide a kind of suitable elastic support member of using the structure of unitary elasticity material formation.Have again, the purpose of this invention is to provide and a kind ofly shake and tilt, fall countermeasure and deposit and the elastic support member of the structure that the adjustment of elastic force is superior.Have again, the purpose of this invention is to provide a kind of be provided with this elastic support member and anti-shaking and precision machinery and portable computer that impact resistance is superior.
Relating to elastic support member of the present invention is made of jut and foot section and bridge formation portion.Jut in quiet supporting surface one side of the first hole portion by the bridge formation portion elastic support that is connected with foot section.The front-end face of jut is more outstanding than quiet supporting surface.Quiet supporting surface be meant from elastic support member remove jut and under the state of not exerting pressure will be with attachment face on elastic support member when being placed on the tabular surface, formed of the foot section of the elastic support member that contacts with tabular surface.When jut is under pressure at front-end face, sink in the first hole portion.At this moment, the first hole portion is provided at when jut sinks and makes bridge formation portion that the space of resiliently deformable take place.Elastic support member is being installed in when shaking on the precision machinery, jut sink in the first hole portion and deflection according to quiet supporting surface and the gap above the desk with share the load decision, thereby support precision machinery and prevent to shake.
Inclination has taken place when being placed on precision machinery above the desk, when falling, the front-end face of initial jut absorbs impact with collision above the desk.When sinking to the first hole portion because of impact relief portion, bridge formation portion performance elastic force and absorb the acceleration of impact.If bridge formation portion mainly utilizes tensile elasticity performance elastic force in the first hole portion, then Billy more can improve the absorptivity of impact with the elastic force of pressure elasticity.If bridge formation portion possesses the criss-cross supporting structure that is made of four joints that combine with the pass through openings sidewall that is formed at foot section, then pass through the size of the excision portion in adjustment bight, can adjust the tensile modulus of elasticity of joint, the Young's modulus in the time of therefore can being convenient to control the jut sinking.Thus, can determine the parameter that realizes, fall and shake and deposit easily.
Criss-cross supporting structure can be excised dull and stereotyped four bights with connecting to the mode of quiet supporting surface side from the attachment face side of joint on every side at the thickness direction of flat board, can also be resected to certain depth.Front-end face arrive behind the quiet supporting surface remaining acceleration since the space that provided of the first hole portion used up, so mainly absorb with the pressure elasticity of bridge formation portion and foot section.When jut formed with elastic material, the pressure elasticity of jut also helps to absorb impacted.When foot section, bridge formation portion and jut utilize pressure elasticity absorb to impact, because as long as absorb the impact of the acceleration that has alleviated by jut, so at this moment can not produce peak value above the peak value of the acceleration that has alleviated by jut.
The first hole portion can open also on attachment face and can not open.Under open situation, the bottom surface of precision machinery is positioned at the limit positions in the space that the first hole portion provided.When bridge formation portion is under pressure at the front-end face of jut, the mode supporting projections portion that can contact with the bottom surface of precision machinery with jut, in addition, the also mode supporting projections portion that can contact with the bottom surface of precision machinery with bridge formation portion.After the bottom surface of jut or bridge formation portion arrival precision machinery, jut and bridge formation portion mainly utilize pressure elasticity and are out of shape, and absorb remaining acceleration with the foot section acting in conjunction.
Foot section comprises a plurality of mountain portion, if be provided with the second hole portion in the behind of each mountain portion, then absorbing when impacting, not only bring into play pressure elasticity in the behind of mountain portion and also brings into play tensile elasticity, can more effectively improve the impact absorption ability.Because elastic support member can utilize a material by the integrally formed integral body of mold, make easily.
In other modes of the present invention, provide a kind of portable computer that elastic support member is installed in the bottom surface.Elastic support member forms with elastic material, and is made of foot section and jut and bridge formation portion.Foot section possesses the attachment face and quiet supporting surface and the first hole portion relative with attachment face that is installed on the portable computer bottom surface.Jut utilizes the bridge formation portion that combines with foot section to support in order to make front-end face more outstanding than quiet supporting surface.On elastic support member, applied portable computer share load the time, jut sinks in the first hole portion till front-end face roughly arrives quiet supporting surface.
Impact that the initial absorption of its jut of elastic support member causes because of tilting, falling and the peak value that reduces acceleration further prevent to shake.When on portable computer is placed on desk and by the elastic support member burden, sharing load, jut sinks in the first hole portion roughly consistent with quiet supporting surface up to front-end face, even so user's frequent slide portable computer on desk, wearing and tearing are also few.If elastic support member is installed near the disk set, then can further improve the impact resistance of portable computer.

Embodiment
Fig. 1 relates to the notebook type home computer's (below, be referred to as notebook PC) of embodiment of the present invention outline drawing.Notebook PC10 constitutes with the display device 11 that hinge combines by apparatus main body 13 with end thereafter.Display device 11 is installed on the cover of notebook PC10, and closing cap when carrying is opened lid in use and utilized display device 11.Be provided with keyboard on apparatus main body 13 surfaces, accommodate the mother board that carried various cards and processor and disk set etc. in inside.
Fig. 2 is the figure of summary structure of the bottom surface 15 of indication device main body 13.Bottom surface 15 forms the face of general planar, and near rearward end 17, battery unit 23 releasably is installed on the apparatus main body 13.In addition, near front end 19, accommodate disk set 21 in the inside of apparatus main body 13.On two bights of front end 19 sides of bottom surface 15, be separately installed with elastic support member 25,27, on two bights of rearward end 17 sides, be separately installed with elastic support member 29,31.These elastic support members 25,27,29,31 are commonly referred to as rubber feet.
Elastic support member can only be installed three for preventing to shake, but in the present embodiment, near rearward end 17, be provided with battery unit 23, can't balancedly support notebook PC10 with three elastic support members, stability in order further to guarantee to use, and be provided with elastic support member 25,27,29,31 in four bights.Four elastic support members 25,27,29,31 are because more outstanding laterally than bottom surface 15, so when being placed on notebook PC10 above the smooth desk, having only elastic support member and contact above the desk.But the framework of constituent apparatus main body 13 need be made light-duty, has also to have manufacturing tolerances, so take place on bottom surface 15 unavoidably that a little is crooked again.In addition, placing above the desk of notebook PC10 neither smooth fully plane but the situation of distortion is in the majority.Therefore, in four elastic support members 25,27,29,31 some not can with contact above the desk, shake thereby produce.
The notebook PC10 that relates to present embodiment is designed to that center of gravity is positioned at rearward end 17 sides when opening display device 11 and use, elastic support member 29 and 31 necessarily with contact above the desk.Therefore, the situation of shaking has taken place, any in the elastic support member 25 or 27 and above the desk between have the gap in vain.Have, elastic support member 27 is configured near the disk set 21 again, and hope absorbs the impact to disk set 21 in run-off the straight, when falling.In relating to embodiments of the present invention, the elastic support member that possesses new structure 100 that provides elastic support member 25 and 27 to be adopted.
Fig. 3 is the figure of the structure of expression elastic support member 100.The figure of the upside of Fig. 3 (A) is the being seen stereogram of attachment face 101 sides from the bottom surface that is installed in notebook PC10, the figure of downside be from the being seen stereogram of supporting surface side that contacts above the desk.Fig. 3 (B) is from the being seen plan view of supporting surface side, and Fig. 3 (C) is from the being seen plan view of attachment face 101 sides, and Fig. 3 (D) is the figure of the A-A section of presentation graphs 3 (B).Elastic support member 100 is the nitrile butadiene rubber of fusion (NBR) to be flow in the mould and by one-body molded make.
When the elastic support member 100 on being installed in bottom surface 15 is subjected to the load of notebook PC10, resiliently deformable takes place in the 111a～111f of mountain portion according to load, increase with the face that desk contacts above, be referred to as moving supporting surface with the face that desk contacts above in this case.The zone of moving supporting surface changes because of the load that is applied in the elastic support portion.Do not have jut at 107,109 o'clock at elastic support member 100, the face that is not subjected to the 111a of the mountain portion～111f contact of the elastic support member 100 of load is referred to as quiet supporting surface.In addition, in this manual, abbreviate the two situation of expression quiet supporting surface and moving supporting surface as supporting surface.Under the situation that the supporting surface side of foot section 110 forms with smooth face, quiet supporting surface is consistent with moving supporting surface, but form as shown in Figure 3 under the wavy situation inconsistent.In Fig. 3 (D), the top of the 111a～111f of mountain portion and above the desk the formed flat table of position contacting be shown quiet supporting surface 119.
Projection 107,109 is supported by bridge formation portion 115,117 to the side-prominent mode of supporting surface than quiet supporting surface 119 with front-end face 107a, 109a.Front-end face 107a, the 109a position that to be jut 107,109 contact above with desk.The known stickup band of elastic support member 100 its attachment face 101 usefulness sticks on the bottom surface 15 of notebook PC10.Attachment face 101 integral body form smooth face, and are formed with the opening portion of hole portion 103,104,105a～105d.In the present invention, explanation is such as described later, hole portion 103,104 is provided for making the space of bridge formation portion distortion when jut 107,109 sinks in the foot section 110, so unnecessary, but be more convenient for making in the method for the situation under shed of casting elastic support member 100 with mold in attachment face 101 upper sheds.
Fig. 4 represents the detailed structure of jut 107 and bridge formation portion 115.Fig. 4 (A) is the figure from attachment face 101 side finding hole portions 103, and Fig. 4 (B) is the figure of the B-B section of presentation graphs 4 (A), and Fig. 4 (C) is the stereogram of jut 107 and bridge formation portion 115.The structure of bridge formation portion 115 is as follows, blocks the pass through openings that forms from the attachment face 101 lateral support face sides of foot section 110, and is formed with hole portion 103 in the attachment face side, is sidelong at supporting surface and puts jut 107.In Fig. 4 (A), the zone of the bridge formation portion 115 of the placement jut 107 shown in the dotted line is called base 115e, other zone is called joint 115a～115e.
The elastic force of jut 107 when hole portion 103 sinks can be revised easily by adjusting the size of the 121a～121d of this excision portion by bridge formation portion 115.Make supporting surface with contacting above the desk from attachment face 101 when elastic support member 100 is exerted pressure, jut 107 sinks to hole portion 103 together with base 115e in the time of the joint of bridge formation portion 115 115a～115d performance tensile elasticity.Under the integrally formed situation of bridge formation portion 115 and jut 107, we can say that also base 115e is the part of jut.
In the present embodiment, the stroke x that front-end face 107a is arrived quiet supporting surface 119 makes equal with the stroke y that face that base 115e contacts with hole portion 103 arrives attachment face 101.In the present embodiment, stroke x selects in 0.5mm～1mm scope.Jut 107 and base 115e are during front-end face 107a sinks in the scope of stroke x, and mainly the tensile elasticity with joint 115a～115d cushions the power that is applied on the front-end face 107a.Because by attachment face 101 with stick on the border that stickup band on the notebook PC bottom surface 15 is determined hole portion 103, so after front-end face 107a arrives quiet supporting surface 119, utilize the elasticity of the 111a～111f of mountain portion and the pressure elasticity of projection 107 and base 115e to cushion the power that is applied on the front-end face 107a.Jut 109 and bridge formation portion 117 also constitute the structure identical with jut shown in Figure 4 107 and bridge formation portion 115.
The effect of shaking and tilting, falling during then, to installation elastic support member 100 on notebook PC10 bottom surface 15 describes.The elastic support member 25,27 of supposing notebook PC10 adopts elastic support member 100.On notebook PC10 is placed on smooth desk and bottom surface 15 also be entirely formed as when smooth, elastic support member 25,27 share respectively notebook PC overall load about 25%.The load that each elastic support member is shared in the mounting point of notebook PC10 is referred to as to share load.Jut 107,109 arrives the elastic force that quiet supporting surface 119 is adjusted bridge formation portion 115,117 for making front- end face 107a, 109a when elastic support member 100 is subjected to sharing load.
Thereby the adjustment of this elastic force is also carried out actual measurement repeatedly by the excision extension that changes the 121a～121d of excision portion gradually and can be adjusted easily.Have in vain under the situation in space at quiet supporting surface 119 with between above the desk, the load of sharing that jut 107 or 109 any or both sides bear notebook PC10 prevents to shake.Because the area of front- end face 107a, 109a is little, thus only front- end face 107a, 109a can gap portion with contact above the desk, shake so can effectively remove.The deflection of jut 107,109 decides according to the balance between the elastic force of the size in the gap in each position and the tensile elasticity by sharing load and bridge formation portion 115,117.
At quiet supporting surface 119 and between above the desk under the situation very close to each other, jut 107 or 109 sinks down into the position of quiet supporting surface 119 because of sharing load its front-end face 107a or 109a.If because the keyboard operation user is placed on the notebook PC10 imposed load again with hand, then the elastic force of the pressure elasticity of jut 107,109 and bridge formation portion 115,117 and the elastic force acting in conjunction of foot section 110 come bearing load.At this moment, foot section 110 supports its load with moving supporting surface, and front- end face 107a, 109a constitute the part of moving supporting surface.During this, because front- end face 107a or 109a can be more not side-prominent to supporting surface than quiet supporting surface 119 and moving supporting surface, even so the user moves when notebook PC10 slides on desk, the degree of jut 107,109 and 115,117 wearing and tearing of bridge formation portion or damage is also little.
Then, illustrate tilting.The effect that falls.The user only make elastic support member 25 with 27 with contact above the desk, and elastic support member 27,31 is floated above desk and keep notebook PC10 with the state that tilts, and when suddenly handle leaves, notebook PC10 falls with gravity accleration, elastic support member 27,31 and colliding above the desk.Can't fully absorb under the situation of impact at elastic support member 27, excessive impact force is delivered on the inner disk set 21 that is held and might makes its breakage.Adopting as elastic support member 27 under the situation of elastic support members 100, front-end face 107a, the 109a of initial jut 107,109 with collide the acceleration of reduction notebook PC10 above the desk.The joint of bridge formation portion 115,117 gives each jut tensile elasticity till front- end face 107a, 109a arrive quiet supporting surface 119.
After front- end face 107a, 109a arrived quiet supporting surface 119, base 115e and attachment face 101 contacted with stickup band on sticking on bottom surface 15, and jut 107,109 can't utilize under the tensile elasticity of bridge formation portion 115,117 and sink to this above stroke.Front- end face 107a, 109a arrive after the quiet supporting surface 119, and jut 107,109 and the base 115e corresponding with it are out of shape because of pressure elasticity, and front- end face 107a, 109a further sink than quiet supporting surface 119.At this moment, in the time of the part of the moving supporting surface of front- end face 107a, 109a formation foot section 110, also lower and fail to absorb and residual remaining acceleration with jut 107,109.The space that the 111a～111f of mountain portion of foot section 110 utilizes the 105a～105d of hole portion to be provided when utilizing the distortion of tensile elasticity and pressure elasticity, reduces remaining acceleration with jut 107,109 actings in conjunction.
Fig. 5 is the data of the acceleration of expression when notebook PC10 carried out inclination, shatter test.In inclination, shatter test, the weight that is equivalent to disk set and the simulation object of volume on notebook PC10, have been carried, degree of will speed up sensor is installed on this simulation object, and in advance elastic support member 25,29 sides are placed on above the desk, and after the mode of 20cm keeps above apart from desk with elastic support member 27,31, it is dropped to above the desk.Test has been carried out 5 times with the same terms.Fig. 5 (A) has been to use the situation of the elastic support member of the structure of removing jut 107,109 from elastic support member 100, and Fig. 5 (B) has been to use the situation of elastic support member 100.The longitudinal axis of Fig. 5 is represented the acceleration that acceleration transducer detects, and transverse axis is represented the transit time.The longitudinal axis of Fig. 5 (A) and Fig. 5 (B) is put down in writing with identical scale.
As Fig. 5 (A) and (B), used the situation of elastic support member 100, to compare with the elastic support member that does not have jut 107,109, the peak value of acceleration is suppressed to about 60%.Because jut 107,109 is till front- end face 107a, 109a arrive quiet supporting surface 119, by allowing the tensile elasticity of the bridge formation portion 115,117 of free deformation can absorb impact in hole portion 103,104, so compare with the existing elastic support member that only impacts, improve the impact absorption ability with the pressure elasticity absorption.The peak value of acceleration is big more, and the influence of the impact that disk set 21 is subjected to is also big more, but elastic support member 100 utilizes jut to effectively reduce the peak value of acceleration, thereby the notebook PC10 that improves impact resistance can be provided.
In the present embodiment, on an elastic support member, be provided with two juts, but can also be provided with more than one or three.In addition, constitute jut and make structure on the base that is placed on bridge formation portion, but make the bottom surface arrival attachment face 101 of jut can also make the lateral junction of bridge formation portion and jut be incorporated in the time.Have, the supporting surface side of foot section 110 constitutes wavy again, but it can also be made smooth face, perhaps forms a plurality of microspikes.
So far utilize specific implementations shown in the drawings that the present invention has been described, but the invention is not restricted to mode of execution shown in the drawings, as long as obtain effect of the present invention certainly, even if existing known any structure also can adopt.
Utilizability on the industry
