From this, because the fabric layer has better tough and soft characteristics, so the buffer layer can have certain toughness and intensity, and when glass housing assembly received the impact force, the fabric layer in the buffer layer can effectually be alleviated, this impact force of dispersion, and then reduce the broken risk of glass body, and then promote glass housing assembly's anti falling performance and intensity, reduce the fracture phenomenon of glass body to prolong its life.

Since the glass strengthening treatment is only surface treatment, the tensile and compressive capacity of the glass can be strong, but the internal influence on the glass is small, the inventor finds that when the glass is subjected to external impact force, the impact force can still be transmitted to the internal part of the glass, and the glass is broken. Especially, the glass with a 3D structure is easy to concentrate at the bent part of the glass due to external impact force, so that the bent part of the glass is poorer in drop resistance and is easier to break when being subjected to the external impact force. Therefore, the buffer layer containing the fabric layer is arranged on one side, close to the decorative layer, of the glass body, the impact force inside the glass body is relieved and dispersed by utilizing the toughness and the strength of the fabric layer, and then the falling resistance and the impact resistance of the glass shell assembly are improved.

Therefore, when the glass shell assembly is subjected to external impact force, the impact force transmitted to the interior of the glass body can be effectively relieved and released, and the glass body is prevented from being broken; moreover, the arrangement mode does not cause the buffer layer to influence the appearance effect of the decorative layer generated on the glass shell assembly.

In other embodiments, the buffer layer is embedded in the decorative layer, i.e. when the decorative layer is composed of a multi-layer film structure, the buffer layer is disposed in the multi-layer film structure. Therefore, when the glass shell assembly is subjected to external impact force, the impact force transmitted to the inside of the glass body can be still effectively relieved and released, and the glass body is prevented from being broken.

Wherein, referring to fig. 4, the decoration layer 20 includes: a UV transfer layer 21, the UV transfer layer 21 being disposed on the first surface; the color layer 22 is arranged on one side, away from the glass body 10, of the UV transfer printing layer 21; bottom-covering ink layer 23, bottom-covering ink layer 23 is disposed on one side of color layer 22 away from glass body 10, and buffer layer 30 is disposed on the surface of bottom-covering ink layer 23 close to glass body 10. Therefore, when the glass shell assembly is subjected to external impact force, the impact force transmitted to the interior of the glass body can be still effectively relieved and released, and the glass body is prevented from being broken; moreover, the side of the cover bottom ink layer 23 close to the glass body (or the color layer) still enables the glass housing assembly to have a better appearance. In some embodiments, can also set up the buffer layer between UV rendition layer and glass body, also can set up the buffer layer between UV rendition layer and colour layer, the impact force that release glass body received all can effectively be alleviated to above-mentioned mode of setting up, promotes glass body's intensity and impact resistance, so technical staff in the art can be according to the design flexibility selection buffer layer's the position that sets up to glass housing assembly outward appearance effect.

In order to further improve the color brightness of the glass shell assembly, the decorative layer can further comprise an indium tin oxide coating layer arranged on the surface of the color layer far away from the glass shell.

Further, referring to fig. 5, the decoration layer may further include a PET substrate 24, and the UV transfer layer 21 is disposed on a side of the PET substrate away from the glass body. Therefore, the preparation of the decorative layer is convenient. In some embodiments, referring to fig. 5, glass body 10 and decorative layer 20 are bonded together by a glue layer 40 (such as OCA glue), i.e., the glue layer is disposed between the PET substrate and the glass body. Thereby, the stability of the glass housing assembly can be improved.
