The use of "including," "comprising," "having," and the like, herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present invention is not limited to the number of the element being one, and may include a plurality of the elements.

As shown in fig. 1-3, the utility model provides a take protective housing 10 of gradual change pattern structure for the cover is in order to protect this electronic equipment on electronic equipment, and electronic equipment for example is cell-phone, panel computer etc. uses the cell-phone to specifically explain as the example in this embodiment, and protective housing 10 is the cell-phone shell promptly. The protective shell 10 includes a shell 12, a decorative layer 14, and a gradual change pattern structure disposed between the shell 12 and the decorative layer 14, wherein the shell 12 includes a back plate 16 and a side frame 18 connected to the periphery of the back plate 16, and the back plate 16 and the side frame 18 surround to form an accommodating space 17 for accommodating the mobile phone. In this embodiment, the protective casing 10 is a half-wrapped structure, and in other embodiments, the protective casing 10 may also be a full-wrapped structure.

The decorative layer 14 is attached to the inner surface of the back panel 16. for example, the decorative layer 14 can be connected to the back panel 16 by snapping, adhering, or injection molding, and in this embodiment, the decorative layer 14 is connected to the back panel 16 by snapping. The gradual change pattern structure comprises a plurality of bulges and a plurality of grooves 20 which are mutually embedded and matched, and the bulges and the grooves 20 are the same in quantity and are in one-to-one correspondence. Wherein, a plurality of protrusions are disposed on the side of the decorative layer 14 opposite to the back panel 16, and a plurality of grooves 20 are disposed on the inner surface of the back panel 16. In the illustrated embodiment, the plurality of grooves 20 are disposed in a middle-lower region of the back plate 16, for example, an upper region of the back plate 16 is provided with a first avoidance hole 22 for avoiding a camera of a mobile phone, and the plurality of grooves 20 are disposed in a region of the back plate 16 below the first avoidance hole 22. Correspondingly, a plurality of protrusions are arranged in the middle-lower area of the decoration layer 14, the upper area of the decoration layer 14 is provided with a second avoidance hole 24 for avoiding a mobile phone camera, and the plurality of protrusions are arranged in the area, located below the second avoidance hole 24, of the decoration layer 14. In other embodiments, the decorative layer 14 is attached to the outer surface of the backing sheet 16, and the arrangement of the protrusions and the grooves 20 is reversed, i.e., the protrusions are disposed on the outer surface of the backing sheet 16 and the grooves 20 are disposed on the side of the decorative layer 14 opposite to the backing sheet 16, and the protrusions and the grooves 20 cooperate to display a gradient pattern on the decorative layer 14.

Preferably, the decorative layer 14 and/or the back panel 16 are made of a translucent material, so that the gradient pattern effect exhibited by the gradient pattern structure can be more clearly displayed from the outside of the decorative layer 14 or the back panel 16.

The heights of at least part of the bulges are set to be different, so that the gradual change pattern structure can present a clear gradual change pattern effect for watching. Correspondingly, the depth of the grooves 20 is matched with the height of the protrusions, so that each protrusion is just embedded in the corresponding groove 20, and the protrusions and the grooves 20 are tightly matched. When the decorative layer 14 is attached to the back panel 16, the protrusions are more visible on the surface of the back panel 16 at the positions with higher protrusions, and less visible on the surface of the back panel 16 at the positions with lower protrusions, so that the protrusions can be arranged on the surface of the back panel 16 in a gradual change manner. Therefore, different effect displays can be realized by arranging the protrusions in different pattern structures in different height structures.

Further, the same projection gradually changes in height in the extending direction thereof, and a pattern gradation effect can also be achieved.

In the illustrated embodiment, the protrusions are arranged in a gradually increasing manner along the length direction from the top to the bottom of the decorative layer 14, and the arrangement manner and the specific groove structure of the grooves 20 are consistent and adapted to the arrangement manner and the specific protrusion structure of the protrusions, so the following only takes the arrangement manner and the specific protrusion structure of the protrusions as an example for detailed description.

The plurality of protrusions include a first protrusion combination, a second protrusion combination and a third protrusion combination, the first protrusion combination, the second protrusion combination and the third protrusion combination are sequentially arranged at intervals along the length direction of the decoration layer 14, the second protrusion combination is located between the first protrusion combination and the third protrusion combination, and the widths of the first protrusion combination, the second protrusion combination and the third protrusion combination are the same. Wherein, first protruding combination includes the first sand grip unit that a plurality of intervals were arranged, and the protruding combination of second includes the second sand grip unit that a plurality of intervals were arranged, and the protruding combination of third includes the third sand grip unit that a plurality of intervals were arranged, and a plurality of first sand grip units, a plurality of second sand grip units and a plurality of third sand grip unit are arranged along the length direction interval of decorative layer 14 respectively.

Preferably, the spacing distance between two adjacent first protruding strip units, the spacing distance between two adjacent second protruding strip units, the spacing distance between two adjacent third protruding strip units, the spacing distance between adjacent first protruding strip units and adjacent second protruding strip units, and the spacing distance between adjacent second protruding strip units and adjacent third protruding strip units are the same.

Further, the first protruding strip unit is a first long protruding strip 26 extending along the width direction of the decoration layer 14; the second protruding strip units comprise a combination of a plurality of second long protruding strips 28 and at least one second short protruding strip 30 arranged at intervals along the width direction of the decoration layer 14, in the illustrated embodiment, one second short protruding strip 30 is provided, and the second short protruding strips 30 are located at one ends of the plurality of second long protruding strips 28; the third rib unit includes a combination of a plurality of third long ribs 32 arranged at intervals in the width direction of the decorative layer 14. Preferably, the arrangement directions of two adjacent second protruding strip units along the width direction of the decoration layer 14 are opposite, and two adjacent third protruding strip units are arranged in a staggered manner.

Preferably, the first long protruding strip 26 may be arranged such that its height gradually decreases from left to right, thereby achieving a pattern gradual change effect from left to right; similarly, the second long ribs 28, the second short ribs 30, and the third long ribs 32 may also be provided so that their heights gradually change from their extending directions.
