Description
Technical field
The invention belongs to the auxiliary products technical field of portable electronics such as mobile phone, relate to a kind of shell of portable electronics, particularly a kind of resistance to impact can better shell.
Background technology
Along with the progress of society, portable electronics such as mobile phone become indispensable instrument in people's life day by day.With the mobile phone is example, and 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 the mobile phone internal structure, but also have certain dustproof 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 earlier often, and the casing ontology of homogeneous thickness is obviously not enough in its place, eight angles structural strength; Therefore, after in a single day mobile phone falls, through regular meeting occur that the mobile phone inner body damages, the hand set machine shell body is in the Jiao Chu breakage that deforms; 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; It is higher to change the casing ontology cost, not only brings financial burden to the consumer, also causes the wasting of resources simultaneously.Also there is same problem for portable electronics such as iPAD, digital camera, portable hard drive, GPS navigation appearance, 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 objective of the invention is to overcome above-mentioned defective, the shock-resistant casing of the better portable electronics of a kind of shock-absorbing capacity is provided.
The shock-resistant casing of portable electronics of the present invention is achieved in that the casing ontology that comprises portable electronics, it is characterized in that the bight of casing ontology is provided with the buffer body to the casing ontology outer projection.
The shock-resistant casing of portable electronics of the present invention improves the core technology principle of shock-absorbing capacity, is to utilize buffer body to increase cushion stroke.With the Iphone4 mobile phone is example, and Iphone4 mobile phone weight is 0.13kg, and when 1 meter highly fell, the speed of landing did
Supposing to impact back speed is zero, and the stiffness curve that is hit when being out of shape of casing ontology and buffer body is linearity, can know according to law of conservation of energy that then 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 present invention.Can know that by the cushion effect formula 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, and ground is rigid grounds such as marble or cement, and 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 the reason that the back mobile phone damages especially easily.If cushion stroke is improved 20 times; Be that cushion stroke is 16mm, then maximum impact force becomes only 16 kilograms, and impact acceleration is merely 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, note that 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 its 0.3～0.5 times along 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 is provided with perpendicular to host buffer, or is provided with perpendicular to the portable electronics primary flat.Generally speaking, the maximum cushioning stroke of buffer body is in the casing ontology except that buffer body at least 2 times of the remainder average thickness.Among the present invention, owing to only buffer body is 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 big, can reaches in the casing ontology except that buffer body 5～40 times of remainder average thicknesss in the part.In addition, in order to guarantee to realize necessary cushion stroke, generally speaking, the thickness of buffer body is in the casing ontology except that 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 processed 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 processed 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 made up of outer sleeve and at least one slide core, when a slide core only is set, is 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 local crowning can be set on buffer body, in order to promote the local elasticity of buffer body; Certainly, buffer body also can directly be processed 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 have extraly damping to be set or to adopt high damping material, the natural damping of buffer body is generally too little, and mobile phone lands can bounce-back after static, forms to land impact once more.If damping is set, and the damping ratio of the impact system that constitutes 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 an 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 part at least is made up 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 present invention can be varied, and it can be partial sphere at least, or local at least spheroid constant current contour moulding shape or cylinder; It can be local at least plant profile; Said plant not only comprises flowers, plants and trees; Also comprising objects such as vegetables, fruit, seed, specifically can be the partial shape at least of 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; Be the real personage of representative with Einstein for example, be the mythical personage of representative with Sun Wukong, with crayon little newly be representative case of caricatures of persons, or be the cartoon figure etc. of representative with happiness sheep sheep; The organ that described in addition local at least personage can also be the personage, for example eye, ear, mouth, nose, the heart, hand, foot etc.; In addition, can also be local at least animal shape, for example 12 symbolic animals associated with a 12 year cycle image, penguin, lion or coccinella septempunctata etc. have also comprised the organ of animal, certainly like ear, pawl, mouth, shell etc.In addition, it is pointed out that in practical application, among the present invention the concrete shape of buffer body can also be the art of above-mentioned people and thing nature shape develop or take out to.
In the shock-resistant casing of portable electronics of the present invention; Except the bight at casing ontology is provided with the buffer body respectively; Can also be along on the angle at same seamed edge two ends on the casing ontology thickness direction integrated continuous buffer body being set, promptly a buffer body has been protected two angles on the casing ontology simultaneously.
Said buffer body can be processed with the casing ontology integral forming when making casing ontology, also can with buffer body through anchoring piece connect, bonding, hinged, screw element connects, securing member connects, draw-in groove connection or fastener ways of connecting are fixed on the casing ontology.Therefore, the selection range of buffer body also very extensively, for example can utilize plastic material that buffer body and casing ontology are once plastified shaping; Also can utilize natural fiber materials such as metal material, plastic material, elastomeric material, polyurethane material, linen-cotton, fibers material or process buffer body earlier, again buffer body is fixed on the casing ontology by at least two kinds of materials in the above-mentioned material.Adopt the independent buffer body that is provided with; Need not change whole casing ontologies when buffer body damages, further enlarge the selection range of buffer body in addition, more help improving 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 process, elasticity is big, and buffer capacity is strong; The buffer body good hand touch of utilizing cotton material to process is not damaged clothing and bag tool; Utilize light metals such as aluminium alloy and leather or the compounded buffer body of elastomeric material more durable, stylishness is stronger or the like, 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 the buffer body on the casing ontology at any time, satisfy variation aesthetic and hobby.
Portable electronics; When for example mobile phone came off from desktop or hand, counting under the situation extremely greatly when landing was that the bight lands earlier, and the hand set machine shell body on the existing market generally adopts the roughly uniform rubber and plastic casing ontology of thickness; Its buffering that provides receives the restriction of casing ontology thickness, and is very limited.If with the thickness uniformly thicken of casing ontology, it is very clumsy that casing ontology becomes again, do not accepted by the fashionable group, also uneconomical in addition.The present invention is provided with the buffer body of protrusion through the bight at casing ontology; The local impact resistance of protected portable electrical equipment and casing ontology significantly is enhanced; Can too much not increase cost, not affect the appearance again, practicality, economy and fail safe are had both.
The shock-resistant casing of portable electronics of the present invention; Through the bight of casing ontology and near buffer body is set, can significantly improve cushion stroke, the impulsive force when reducing the portable electronics accident and landing; Improved local impact resistance; Damage is avoided in the bight that can effectively guarantee the Electric Apparatus Chassis body when bearing external impact, help prolonging the useful life of product, improves security performance.The shock-resistant casing of portable electronics of the present invention, simple in structure, not only kept all advantages of original casing ontology; Form is more various simultaneously; Vivid and interesting, practical, improved the impact resistance of product greatly; Can be widely used in portable electronics such as mobile phone, walkman, electronic dictionary, ipad, digital camera, portable hard drive, GPS navigation appearance, notebook computer, calculator, market application foreground is very wide.
