Technical Field

[0001] The utility model relates to the technical field of mobile phone protection devices, and specifically relates to a shock-absorbing rear cover. Background Technique

[0002] The existing shock-absorbing method of mobile phone casings mainly involves pasting shock-absorbing foam pads on the rear cover of the mobile phone for each component of the mobile phone. During the use of this method, since the thickness of the cotton pads is uniform and it is difficult to adjust the thickness of the cotton pads, and at the same time, the thickness of the internal components of the mobile phone varies, resulting in an uneven situation of the internal components of the mobile phone. Through the pasting method of the cotton pads, there may be a certain gap between the internal components of the mobile phone and the cotton pads, thereby resulting in insufficient shock-absorbing effect. Therefore, we design a new technical solution to solve the traditional technical problems. Summary of the Invention

[0006] Furthermore, the heat dissipation sheet is a graphene material thin sheet, and its shape fits the airbag pad.

[0007] Furthermore, the rear cover is also equipped with a lens protection cover, and shock-absorbing foam pads are respectively provided on both sides of the lens protection cover. The surface of the shock-absorbing foam pad is adhesively connected to the inner surface of the rear cover, and the shock-absorbing foam pad is made of polyurethane material.
