The application is the Application No. 201210111661.2 that applicant submitted on 04 17th, 2012, entitled The divisional application of " the impact resistance containment vessels of portable electronics ".
Technical field
The invention belongs to the auxiliary products technical field of the portable electronics such as mobile phone, is related to one kind and is placed in portable electronics table The containment vessel in face, the more preferable containment vessel of particularly a kind of impact resistance.
Background technology
As the portable electronics such as the progress of society, mobile phone have been increasingly becoming instrument indispensable in people's life.With As a example by mobile phone, current various functions are comprehensive, the mobile phone that profile is magnificent emerges in an endless stream, and many mobile phones are expensive, in order to avoid During routine use there is abrasion or scratch in mobile phone surface, and many people select to be equipped with a protection shell to mobile phone.At present, city Mobile phone productses protection shell on face is typically made using rubber and plastic Shooting Technique, after use, it is possible to achieve the guarantor to mobile phone surface Shield, but also with certain dust-proof effect.But, existing protective casing of cell phone is typically tied using the housing of same thickness Structure, according to general knowledge it is recognised that when mobile phone surprisingly falls from eminence, often corner first lands, and homogeneous thickness Protection shell structural strength at its eight angles is substantially not enough, therefore, there is interior of mobile phone zero after falling, often in mobile phone Part damage, fuselage and protection shell Jiao Chu deform breakage or touch screen rupture etc. phenomenon, it is impossible to be further continued for using, can only Change.The especially current same portion's regular handset of replacing price of the touch screen of the brand mobile phone such as iPhone of Apple on the market Almost, it is expensive as the protection shell same price of accessory, change and protect shell relatively costly, not only bring Jing to consumer Ji burden, while also resulting in the wasting of resources.For iPAD, digital camera, portable hard drive, GPS navigator, notebook computer, meter Calculate the portable electronics such as device and there is also same problem.In sum, existing portable electronics protect the buffer capacity of shell not Foot, the not good problem of protected effect need to improve.
The content of the invention
It is an object of the invention to overcome drawbacks described above, there is provided a kind of impact resistance of the more preferable portable electronics of shock-absorbing capacity Containment vessel.
The impact resistance containment vessel of portable electronics of the present invention to be achieved in that and be arranged on portable electronics table including additional The protection shell that face is adapted with portable electronics profile, it is characterised in that the corner of protection shell or/and adjacent corner are arranged To the buffer body that protection housing exterior is raised.
The impact resistance containment vessel of portable electronics of the present invention improves the core technology principle of shock-absorbing capacity, is using buffering Body increases cushion stroke.By taking Iphone4 mobile phones as an example, Iphone4 mobile phones weight is 0.13kg, when falling from 1 meter of height, is fallen Ground speed beAssume that speed is zero after impact, protect shell and buffer body be hit deformation when Stiffness curve is linearly, then it can be seen from law of conservation of energy, the maximum impact force suffered by mobile phone is Fmax=mv2/ s, wherein S is damping of shocks stroke, this formula abbreviation cushion effect formula in the present invention.From cushion effect formula, impulsive force and quality, Landing speed is directly proportional, and is inversely proportional to cushion stroke.The protection shell for assuming generic homogeneous thickness is 1.2mm, and protection shell delays It is 0.8mm to rush stroke, and ground is the rigid ground such as marble or cement, then maximum impact force is 3189N, is converted into 325 kilograms, Maximum impact acceleration is the acceleration of gravity of 2500g, i.e., 2500.Here it is dropping rear mobile phone why is particularly easy to what is damaged Reason.If unprotected shell, cushion stroke is shorter, mobile phone is easily damaged.If cushion stroke is improved into 20 times, that is, delay It is 16mm to rush stroke, then maximum impact force is changed into only 16 kilograms, and impact acceleration is only 125g, it can be seen that, increase buffering row Journey, can effectively reduce the maximum impact force and impact acceleration when portable electronics land, so as to significantly reduce to mobile phone Infringement.In order to reach preferable buffering effect, should be noted when buffer body is designed, it is preferred that buffer body should meet following requirement： The maximum cushioning stroke of buffer body more than landing speed designs value square with the ratio of impact acceleration maximum permissible value；Buffer body Along the axial rigidity of host buffer be land kinetic energy design value and maximum cushioning stroke square 2 times of ratio；Buffer body is along secondary It is it along 0.3～0.5 times of the axial rigidity of host buffer to buffer axial rigidity.Wherein, the host buffer axle of buffer body refers to Extend to the barycenter of portable electronics, or angular bisector of projection of the host buffer axle in electrical equipment principal plane along adjacent both sides；It is slow The secondary buffer shaft for rushing body is axially arranged perpendicular to host buffer, or arranges perpendicular to portable electronics principal plane.Generally, delay The maximum cushioning stroke for rushing body is protected in shell except at least 2 times of the external remainder average thickness of buffering.In the present invention, by In only arranging buffer body in local, and using highly elastic material or high-elastic structure in buffer body, therefore buffer body is slow Rush stroke very big, up to removing in protection shell external 5～40 times of remainder average thickness is buffered.In addition, in order to ensure to realize Necessary cushion stroke, generally, the thickness of buffer body is except the external remainder average thickness of buffering in protection shell At least 3 times, according to actual needs, it might even be possible to for 10～50 times.
In order to improve the elasticity of buffer body, increase cushion stroke, highly elastic material or high-elastic can be set in buffer body Property structure.For example, helical spring structure can be set in buffer body, helical spring structure by metal material or elastomeric material, Or polyurethane material or plastic material are made, or it is composited by above-mentioned material；Bending bullet can also be set in buffer body Spring structure, flexural spring structure is made up of metal material or elastomeric material or polyurethane material or plastic material, or by upper State Material cladding to form；Can to arrange shear spring structure in buffer body, shear spring structure by base and kinetoplast and with And elastomeric material composition therebetween；Further, it is also possible to arrange stretching structure in buffer body, stretching structure by outer sleeve and At least one slide core is constituted, and when a slide core is only arranged, between outer sleeve and a unique slide core friction is provided with Secondary or/and damping pore, when multiple slide cores are provided with, between outer sleeve and slide core and slide core is adjacent is connected Slide core between be respectively provided with friction pair or/and damping pore；Can also local crowning be set on buffer body, to be lifted The local elasticity of buffer body；Certainly, buffer body directly can also be made up of elastic polymer material, and elastic polymer material includes Elastomeric material, PVC material or polyurethane material.In addition, if buffer body damps or adopts high damping material without extra setting, The natural damping of buffer body is general too little, can rebound after mobile phone landing is static, forms landing impact again.If arranging damping, And the close critical damping of damping ratio of impact system that electrical equipment and buffer body constitute when contacting to earth is made, it is just no longer anti-after electrical equipment is static Bullet, damping now is optimal damper.Being provided with another benefit of optimal damper is, in same cushion stroke and same rushes Under hitting power effect, more impact energys can be consumed, higher landing impact velocity can be absorbed.And hence it is also possible to slow Damping structure is set up in vivo in punching, for example, in buffering closed cavity, sky that is closed and being provided with fluid damping material is arranged in vivo Chamber, the cavity with open pore damping structure, adhesion-type damping structure or hole throttle type damping structure.Certainly, buffer body At least partly can also be made up of solid damping material, solid damping material includes high-damping rubber or high-damping polyurethane.It is excellent Choosing, the damping size of damping structure is designed according to the critical damping under most common conflicting model.
The shape of heretofore described buffer body can be with varied, and it can be at least partial sphere or at least office Portion's spheroid constant current contour moulding shape or cylinder；Can be at least local vegetation profile, plant described herein not only includes Flowers, plants and trees, can be specifically flower, Christmas tree, Semen arachidis hypogaeae, Semen Pisi sativi, Fructus Cucurbitae moschatae, Herba Marsileae Quadrifoliae also including objects such as veterinary antibiotics, seeds Really, at least part of shape of the object such as Fructus Fragariae Ananssae, Fructus Citri tangerinae or Citrullus vulgariss；Can also be at least local personage profile, described personage's bag Include real and virtual personage, such as the real personage with Einstein as representative, the mythical personage with Sun Wukong as representative, with Crayon is little new for the case of caricatures of persons of representative or to like the cartoon figure of sheep sheep as representative etc., in addition described at least people from local Thing can also be the organ of personage, such as eye, ear, mouth, nose, the heart, handss, foot etc.；Further, it is also possible to be at least outside the animal of local Shape, such as 12 symbolic animals associated with a 12 year cycle image, penguin, lion or coccinella septempunctata etc., also include the organ of animal certainly, such as ear, pawl, mouth, Shell etc..In addition, it is necessary to, it is noted that in actual applications, in the present invention concrete shape of buffer body can also be above-mentioned people with The art of thing nature shape is developed or pumped to.
In the impact resistance containment vessel of portable electronics of the present invention, except being respectively provided with buffer body in the corner of protection shell Outward, can be with setting integration continuous buffer body, i.e., one on the angle at same seamed edge two ends along protection outer casing thickness direction Individual buffer body protects two angles on protection shell simultaneously.
The buffer body can be made in manufacture protection shell with protection shell integral forming, it is also possible to by buffer body Connect, be hinged anchoring piece connection, bonding, screw element, securing member connection, being fixed on by way of draw-in groove connection or fastener connection On protection shell.Therefore, the selection range of buffer body is also quite varied, for example can be using plastic material is by buffer body and protects Plastics molding of shell；Can also be using natural fibres such as metal material, plastic material, elastomeric material, polyurethane material, linen-cottons Dimension material, fibers material or by above-mentioned material at least two kinds materials first make buffer body, then buffer body is fixed on into guarantor On shield shell.Using the buffer body being independently arranged, buffer body need not change all protection shells when damaging, additionally further The selection range of buffer body is expanded, is more beneficial for improving shock resistance, the resisting breakage performance of buffer body, its texture and form are more Rich and varied, feature is also distincter.For example, using buffer body made by elastomeric material, elasticity is big, and buffer capacity is strong；Using cotton Buffer body good hand touch made by material, damaging laundry and bag do not have；Answered using the light metals such as aluminium alloy and leather or elastomeric material Buffer body is more durable made by conjunction, and stylishness is higher etc., coordinates various colors, can meet the different need of different crowd Ask.Additionally, after by connecting interface standardization of the protection shell with buffer body, the versatility of buffer body can also be realized, it is easy to The buffer body on protection shell is changed at any time, meets aesthetic and hobby change.
