Description

Novel rubber shock attenuation prevents falling cell-phone shell

Technical Field

The utility model belongs to the technical field of the cell-phone shell, specifically be a novel rubber shock attenuation prevents falling cell-phone shell.

Background

At present, large-screen smart phones are more and more widely popularized and used, screens are larger and larger, a potential risk is brought along therewith, once the smart phones fall down, the screens are larger, the screens are cracked due to the impact force of the falling down, slight people also have a plurality of cracks, serious people and even the whole screens are cracked, users need to replace the screens, the screens belong to expensive parts in the smart phones, the replacement of the screens brings high maintenance cost to the users, and therefore mobile phone shells need to be sleeved.

The anti effect of falling of traditional cell-phone shell shock attenuation is not good, consequently needs a novel rubber shock attenuation to prevent falling cell-phone shell.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel rubber shock attenuation prevents falling cell-phone shell to solve the problem that cell-phone shell shock attenuation anti falling performance is not enough among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel rubber shock attenuation prevents falling cell-phone shell, includes shock attenuation shell and supports the inner shell, the shock attenuation shell is located the outer end that supports the inner shell, the four corners of shock attenuation shell is provided with the cushion chamber, the edge of cushion chamber is provided with the gas pocket, the upper end edge of supporting inner shell and shock attenuation shell is provided with prevents falling the strip, be provided with the cushion column in the middle of the four sides of shock attenuation shell, the hot welding fixed connection is passed through with the edge that supports the inner shell to the shock attenuation shell.

Preferably, damper housing adopts the natural rubber material to make, and the rubber material has good anti-falling shock-absorbing capacity, and damper housing falls the ground earlier when the cell-phone falls, cushions the shock attenuation.

Preferably, support the inner shell and adopt stereoplasm PVC material to make, support the inner shell and prop up the shock attenuation shell, block simultaneously on the frame of cell-phone, can not the slippage easily.

Preferably, the buffer cavity is an L-shaped arc hollow cavity, the air hole is a round through hole, the corner is most easily damaged when the corner lands due to the structural characteristics of the mobile phone, the corner is buffered by the buffer cavity, when the corner lands, the mobile phone extrudes the buffer cavity, and the buffer cavity extrudes air to be slowly exhausted outwards through the air hole, so that the force unloading buffering is performed.

Preferably, the cushion column is circular-arc rubber column, the cushion column makes with shock attenuation shell integrated into one piece, and frame department adopts thickening cushion column to unload the power buffering, further reduces the impact force that receives when frame department falls to the ground.

Preferably, the anti-falling strip is of a rectangular annular structure and attached to the upper end face of the mobile phone screen, so that the risk of screen breakage caused by landing of the screen is reduced.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a cushion chamber protects the cell-phone turning, and the protection is strengthened to the cell-phone side to the bumping post, adopts and prevents falling the strip and protect the cell-phone screen, realizes that the omnidirectional shock attenuation of cell-phone prevents falling, has promoted the degree of protection of cell-phone greatly.

Detailed Description

Please refer to fig. 1, a novel rubber shock attenuation prevents falling cell-phone shell, including shock attenuation shell 2 and support inner shell 1, shock attenuation shell 2 is located the outer end that supports inner shell 1, the four corners of shock attenuation shell 2 is provided with integrated into one piece's cushion chamber 21, air hole 211 is seted up at the edge of cushion chamber 21, the upper end edge that supports inner shell 1 and shock attenuation shell 2 is provided with integrated into one piece prevents falling strip 11, be provided with integrated into one piece's cushion column 22 in the middle of the four sides of shock attenuation shell 2, shock attenuation shell 2 passes through hot welding fixed connection with support inner shell 1.

Referring to fig. 1 and 2, the buffer cavity 21 is an L-shaped arc hollow cavity, the air hole 211 is a circular through hole, the corner is most easily damaged when the corner lands due to the structural characteristics of the mobile phone, the corner is buffered by the buffer cavity 21, when the corner lands, the mobile phone presses the buffer cavity 21, and the buffer cavity 21 presses air to be slowly exhausted outwards through the air hole 211 to perform force unloading buffering.

Please refer to fig. 3 and 4, the buffer column 22 is an arc rubber column, the buffer column 22 and the shock-absorbing housing 2 are integrally formed, the thickened buffer column 22 is adopted at the frame, so as to further reduce the impact force when the frame falls to the ground, the anti-falling strip 11 is a rectangular ring structure, the anti-falling strip 11 is attached to the upper end surface of the mobile phone screen, and the screen breaking risk caused by the falling of the screen is reduced.

The working principle of the scheme is as follows: the utility model discloses when using, arrange the cell-phone in the inside of supporting inner shell 1, fall when the cell-phone, when the cell-phone turning lands, cell-phone extrusion cushion chamber 21, cushion chamber 21 extrudes inside air by the slow outside exhaust of bleeder vent 211, unload the power buffering, when the cell-phone frame lands, thickened buffering post 22 unloads the power buffering, the impact force that receives when further reducing frame department and falling to the ground, when the screen lands, prevent falling the damping shell 2 on 11 surfaces and reduce the garrulous screen risk that the screen landed and caused.

The utility model discloses a cushion chamber 21 protects the cell-phone turning, and the protection is strengthened to cell-phone side face by cushion column 22, adopts and prevents falling strip 11 and protect the cell-phone screen, realizes that the omnidirectional shock attenuation of cell-phone prevents falling, has promoted the degree of protection of cell-phone greatly.
