Memory alloys, i.e., alloys possessing a shape memory effect that takes one shape in a low temperature phase and is capable of transforming to another shape when the ambient temperature exceeds a critical temperature; memory alloys are broadly divided into three types: the one-way memory alloy deforms at low temperature and recovers the shape before deformation after heating, namely, the shape memory phenomenon exists only in the heating process; the two-way memory alloy is heated to recover the shape of a high-temperature phase and cooled to recover the shape of a low-temperature phase; the whole course of the memory alloy is heated to restore the same shape at high temperature, and becomes the shape of the low-temperature phase with the same shape and opposite orientation when cooled down.
Disclosure of Invention
Aiming at the problems, the invention provides a falling-prevention mobile phone shell which is light in weight, can effectively reduce the impact force when the mobile phone falls and can protect the screen; the heat conduction and radiation effects are good; meanwhile, the movable brand logo is provided, and the appearance is more exquisite.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the anti-falling mobile phone shell comprises a hard and hollow back plate and a soft and elastic and hollow frame; the back plate is communicated with the hollow area of the frame to form a sealed space; liquid is filled in the sealed space; a freely movable and closed elastic air bag is also arranged in the hollow area of the back plate; the outside of the elastic air bag is wrapped with a closed flow-limiting shell made of transparent material, and flow-limiting holes are circumferentially arranged on the flow-limiting shell at equal intervals; and memory metal sheets with a two-way memory effect are also circumferentially and equidistantly arranged on the outer wall of the current-limiting shell, and each memory metal sheet is perpendicular to the outer wall of the current-limiting shell.
The invention has the beneficial effects that: under the natural state, the frame and the back plate are filled with liquid; when the mobile phone falls off carelessly, the frame is extruded to be concave and deformed at the moment when the mobile phone falls on the ground; the volume of the closed space is reduced, and the hydraulic pressure is increased; the suddenly increased hydraulic pressure extrudes the elastic air bag, the elastic air bag is compressed and contracted, the internal air pressure is gradually increased, and the external hydraulic pressure is gradually balanced; in the process of impacting the mobile phone, the mobile phone shell converts impact force into hydraulic pressure through liquid and transmits the hydraulic pressure to the elastic air bag, and the elastic air bag contracts and buffers the impact force; compared with the traditional mobile phone shell, the mobile phone shell has the advantages that the impact force is limited in the mobile phone shell, so that the screen is prevented from being instantaneously impacted, and the probability of screen breakage is effectively reduced; this dropproof cell-phone shell is another characteristics: impact resistance at each position of the mobile phone frame is balanced, so that the mobile phone is protected more comprehensively; because the impact force in any direction is transmitted to the elastic air bag through the liquid, the shock can be effectively absorbed when the frame is impacted at any position.
During production, the speed of liquid flowing into the flow-limiting shell instantly can be controlled by adjusting the flow-limiting hole on the flow-limiting shell, so that the extrusion speed of hydraulic pressure on the elastic air bag is controlled, and the buffer speed is further controlled; therefore, the frame in the invention can be made of very wide materials, and the buffering effect of the anti-falling mobile phone shell can be most reasonable only by adjusting the aperture and the number of the flow limiting holes according to the elastic coefficients and the toughness of different materials.
In addition, the specific heat of the liquid is large, so that the heat generated by the mobile phone can be effectively absorbed, and the effect of cooling is achieved; when the mobile phone is used, the heat is only concentrated in a partial area, but the whole mobile phone is not uniformly heated, so that the temperature of the liquid in the back plate is unbalanced, when the temperature of a part of memory metal sheet on the current-limiting shell is raised to reach a critical temperature, the part of memory metal sheet is deformed and converted into a high-temperature phase shape, and the memory metal sheet stirs the liquid and drives the current-limiting shell to move when the memory metal sheet is deformed; when the memory metal sheet of the high-temperature phase moves to the low-temperature region, the memory metal sheet deforms again and is converted into the shape of the low-temperature phase, and the flow limiting shell is pushed to move again; the heat of the mobile phone is used for doing work on the current limiting shell, so that part of heat energy is effectively consumed, and preliminary heat dissipation is carried out; meanwhile, in the moving process of the flow limiting shell, the liquid in the back plate is stirred and mixed; so that the liquids with different temperatures are quickly balanced and reach the same temperature, and further the effect of accelerating heat dissipation is achieved; meanwhile, the irregular movement of the current limiting shell enables the mobile phone to be more vivid and interesting.
Preferably, a pattern or a brand logo is attached to the surface of the elastic air bag; in the use process, the brand logo can freely move along with the elastic air bag, so that the interestingness of the mobile phone is increased, the mobile phone is more attractive, and the brand logo is more striking.
Preferably, the elastic air bag is coated with a fluorescent layer; so as to enhance the aesthetic appearance of the handset.
Preferably, the buoyancy of the elastic air bag is equal to the gravity of the elastic air bag and the flow-limiting shell; so that the elastic air bag is in a suspension state, and the moving range of the elastic air bag in the back plate is further expanded.
