Description
Technical field
The utility model belongs to the auxiliary products technical field of the portable electronics such as mobile phone, relates to a kind of shell of portable electronics, and particularly a kind of resistance to impact can better shell.
Background technology
Along with the progress of society, the portable electronics such as mobile phone become indispensable instrument in people's life day by day.Take mobile phone as example, current various complete functions, the mobile phone that profile is magnificent emerge in an endless stream, and many mobile phones are expensive.At present, mobile phone products casing ontology on the market generally adopts the rubber and plastic Shooting Technique to make, and after the use, can realize the protection to internal structure of mobile phone, but also have certain dust-proof effect.But; the general shell structure that adopts same thickness of existing hand set machine shell body, we can know according to general knowledge, when mobile phone during from the eminence accidental fall; the bight lands first often; and the casing ontology of homogeneous thickness is obviously not enough in its place, eight angles structural strength, therefore, and after in a single day mobile phone falls; interior of mobile phone damage parts, hand set machine shell body often can appear in the Jiao Chu breakage that deforms; the phenomenons such as serious even generation touch screen breaks can't continue to use again, can only change.Especially at present same regular handset of replacing price of the touch screen of the brand mobile phones such as iPhone of Apple is similar on the market, the casing ontology same price as accessory is expensive, change the casing ontology cost higher, not only bring financial burden to the consumer, also cause the wasting of resources simultaneously.Also there is same problem for portable electronics such as iPAD, digital camera, portable hard drive, GPS navigation instrument, notebook computer, calculators.In sum, the buffer capacity of existing portable electronics casing ontology problem not enough, the protection poor effect is badly in need of improving.
Summary of the invention
The purpose of this utility model is to overcome defects, and the shock-resistant casing of the better portable electronics of a kind of shock-absorbing capacity is provided.
The shock-resistant casing of the utility model portable electronics is achieved in that the casing ontology that comprises portable electronics, it is characterized in that the bight of casing ontology arranges to the buffer body of casing ontology outer projection.
The shock-resistant casing of the utility model portable electronics improves the core technology principle of shock-absorbing capacity, is to utilize buffer body to increase cushion stroke.Take the Iphone4 mobile phone as example, Iphone4 mobile phone weight is 0.13kg, and when highly falling from 1 meter, the speed of landing is
Speed is zero after supposing to impact, and the stiffness curve that is hit when being out of shape of casing ontology and buffer body is linearity, and then according to law of conservation of energy as can be known, the suffered maximum impact force of mobile phone is Fmax=mv
2/ s, wherein s is the damping of shocks stroke, this formula is called for short the cushion effect formula in the utility model.By the cushion effect formula as can be known, impulsive force is directly proportional with quality, the speed of landing, and is inversely proportional to cushion stroke.The casing ontology of supposing common uniform thickness is 1.2mm, the casing ontology cushion stroke is 0.8mm, ground is the rigid grounds such as marble or cement, then maximum impact force is 3189N, be converted into 325 kilograms, the maximum impact acceleration is 2500g, i.e. 2500 acceleration of gravity, and why Here it is drops that rear mobile phone is special to hold flimsy reason.If cushion stroke is improved 20 times, be that cushion stroke is 16mm, then maximum impact force becomes only 16 kilograms, impact acceleration only is 125g, this shows, increase cushion stroke, maximum impact force and impact acceleration in the time of can effectively reducing portable electronics and land, thus significantly reduce infringement to mobile phone.In order to reach desirable buffering effect, when the design buffer body, should be noted, preferred, buffer body should satisfy following requirement: the maximum cushioning stroke of buffer body greater than land the 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; It is that it is along 0.3～0.5 times of the axial rigidity of host buffer that buffer body cushions axial rigidity along pair.Wherein, the host buffer axle of buffer body points to the barycenter of portable electronics, or the projection of host buffer axle in the electrical equipment primary flat is along the angular bisector extension on adjacent both sides; The secondary buffer shaft of buffer body axially arranges perpendicular to host buffer, or arranges perpendicular to the portable electronics primary flat.Generally speaking, the maximum cushioning stroke of buffer body is in the casing ontology except buffer body at least 2 times of the remainder average thickness.In the utility model, owing to only in the part buffer body being set, and in buffer body, adopt highly elastic material or high-elastic structure, so the cushion stroke that buffer body can be realized is very large, can reaches in the casing ontology except buffer body 5～40 times of remainder average thicknesss.In addition, in order to guarantee to realize necessary cushion stroke, generally speaking, the thickness of buffer body is in the casing ontology except buffer body at least 3 times of the remainder average thickness, according to actual needs, even can be 10～50 times.
In order to improve the elasticity of buffer body, increase cushion stroke, highly elastic material or high-elastic structure can be set in buffer body.For example, helical spring structure can be set in buffer body, helical spring structure is made by metal material or elastomeric material or polyurethane material or plastic material, perhaps is composited by above-mentioned material; Also the flexural spring structure can be set in buffer body, the flexural spring structure is made by metal material or elastomeric material or polyurethane material or plastic material, perhaps is composited by above-mentioned material; The shear spring structure can also be set in buffer body, the shear spring structure by base and kinetoplast and and elastomeric material between the two form; In addition, stretching structure can also be set in buffer body, stretching structure is comprised of outer sleeve and at least one slide core, when a slide core only is set, be provided with friction pair or/and the damping pore between outer sleeve and the unique slide core, when being provided with a plurality of slide core, respectively friction pair is set or/and the damping pore between outer sleeve and the slide core and between slide core and its contiguous slide core that links to each other; Also can local crowning be set at buffer body, in order to the local elasticity of Promoting Layered Buffer body; Certainly, buffer body also can directly be made by the elasticity macromolecular material, and the elasticity macromolecular material comprises elastomeric material, PVC material or polyurethane material.In addition, if buffer body does not additionally arrange damping or adopts high damping material, the natural damping of buffer body is generally too little, and mobile phone lands can bounce-back after static, forms again to land impact.If damping is set, and the damping ratio of the impact system that consists of when electrical equipment and buffer body are contacted to earth is near critical damping, just electrical equipment static after no longer bounce-back, the damping of this moment is optimal damper.Another benefit that is provided with optimal damper is, under same cushion stroke and same impact force action, can consume more impact energy, can absorb the higher impact velocity of landing.Therefore, can also in buffer body, set up damping structure, for example, airtight cavity, airtight and be provided with cavity, the cavity with open pore damping structure, adhesion-type damping structure or the hole throttle type damping structure of fluid damping material is set in buffer body.Certainly, buffer body can also at least part ofly be made of the solid damping material, and the solid damping material comprises high-damping rubber or high-damping polyurethane.Preferably, the damping size of damping structure designs according to the critical damping under the most common conflicting model.
The shape of buffer body described in the utility model can be varied, and it can be at least partial sphere or local at least spheroid constant current contour moulding shape or cylinder; It can be local at least plant profile, plant described herein not only comprises flowers, plants and trees, also comprising the objects such as vegetables, fruit, seed, specifically can be at least part of shape of the objects such as flower, Christmas tree, peanut, pea, pumpkin, apple, strawberry, orange or watermelon; It also can be local at least personage's profile, described personage comprises reality and virtual personage, such as the real personage take Einstein as representative, mythical personage, little newly as the case of caricatures of persons of representative or the cartoon figure take happiness sheep sheep as representative etc. take crayon take Sun Wukong as representative, in addition described local at least personage can also be the personage organ, such as eye, ear, mouth, nose, the heart, hand, foot etc.; In addition, can also be local at least animal shape, such as 12 symbolic animals associated with a 12 year cycle image, penguin, lion or coccinella septempunctata etc., certain organ that has also comprised animal is such as ear, pawl, mouth, shell etc.In addition, it is pointed out that in actual applications, the concrete shape of buffer body can also be the art differentiation of above-mentioned people and thing nature shape or pump in the utility model.
In the shock-resistant casing of the utility model portable electronics; except the bight at casing ontology arranges respectively the buffer body; can also integrated continuous buffer body be set at the angle along same seamed edge two ends on the casing ontology thickness direction, namely a buffer body has been protected two angles on the casing ontology simultaneously.
Described buffer body can be made with the casing ontology integral forming when making casing ontology, also can with buffer body by anchoring piece connect, bonding, hinged, screw element connects, securing member connects, draw-in groove connects or the mode of fastener connection be fixed on the casing ontology.Therefore, the selection range of buffer body is also very extensive, for example can utilize plastic material that buffer body and casing ontology are once plastified shaping; Also can utilize the natural fiber materials such as metal material, plastic material, elastomeric material, polyurethane material, linen-cotton, fibers material or make first buffer body by at least two kinds of materials in the above-mentioned material, again buffer body is fixed on the casing ontology.Adopt the independent buffer body that arranges, buffer body does not need to change whole casing ontologies when damaging, and has further enlarged in addition the selection range of buffer body, more is conducive to improve shock resistance, the resisting breakage performance of buffer body, its texture and form are more rich and varied, and characteristics are also distincter.For example, the buffer body that adopts elastomeric material to make, elasticity is large, and buffer capacity is strong; The buffer body good hand touch of utilizing cotton material to make is not damaged clothing and bag tool; Utilize the light metals such as aluminium alloy and leather or the compounded buffer body of elastomeric material more durable, stylishness is stronger etc., cooperates various colors, and various moulding can be satisfied the different demands of different crowd.In addition, after the connecting interface standardization with casing ontology and buffer body, can also realize the versatility of buffer body, be convenient to change at any time the buffer body on the casing ontology, satisfy variation aesthetic and hobby.
Portable electronics, when for example mobile phone came off from desktop or hand, absolutely greatly counting in the situation when landing was that the bight lands first, and the hand set machine shell body on the existing market generally adopts roughly uniform rubber and plastic casing ontology of thickness, its buffering that provides is subjected to the restriction of casing ontology thickness, and is very limited.If with the even thickness thickening of casing ontology, it is very clumsy that casing ontology becomes again, do not accepted by the fashionable group, also uneconomical in addition.The utility model arranges the buffer body of protrusion by the bight at casing ontology; the impact resistance of protected portable electrical equipment and casing ontology part significantly is enhanced; can too much not increase cost, not affect the appearance again, practicality, economy and fail safe are had both.
