[0021] Please refer to Figures 1 to 2 , the present utility model provides a suitcase shell with a color-changing function under visible light. The suitcase shell with a color-changing function under visible light includes an inner layer 10, an inner liner 20, a functional layer 30 and a bearing layer 40. The inner layer 10 is disposed on the inner side of the inner liner 20. The functional layer 30 is coated on the bearing layer 40, and the bearing layer 40 is combined with the outer side surface of the inner liner 20 by means of hot pressing. The functional layer 30 is sandwiched between the bearing layer 40 and the inner liner 20.

[0022] Specifically, the inner layer 10 is integrally arranged in a shell-like structure that is concave inward on one side, and the inner layer 20 is also integrally arranged in a shell-like structure that is concave inward on one side. The materials of the inner layer 10 and the inner layer 20 are both polycarbonate, and the material of the inner layer 10 is recycled and reused polycarbonate. The inner layer 10 and the inner layer 20 are co-extruded by a drawbench through a dispenser. The inner layer 10 and the inner layer 20 are fixed by hot pressing or ultrasonic welding, so that the outer side surface of the inner layer 10 is tightly fixed to the inner side surface of the inner layer 20.

[0023] A receiving groove 41 is provided inside the bearing layer 40. The outer shape of the receiving groove 41 corresponds to the outer shape of the preset pattern of the box shell. The bearing layer 40 is made of polycarbonate with a transparent structure. The functional layer 30 is coated in the receiving groove 41 of the bearing layer 40. When the bearing layer 40 is combined with the outer side surface of the inner layer 20 by hot pressing, the functional layer 30 in the receiving groove 41 is avoided to prevent damage to the characteristics of the functional layer 30 during the hot pressing process. Specifically, when the bearing layer 40 is combined with the outer side surface of the inner layer 20 by hot pressing, a connecting layer 50 is generated between the bearing layer 40 and the inner layer 20, and the connecting layer 50 and the receiving groove 41 are arranged in a vertical dislocation.

[0024] The material of the functional layer 30 is a photosensitive color-changing coating. The photosensitive color-changing coating absorbs ultraviolet light or sunlight after being irradiated by ultraviolet light or sunlight, and then produces a color change. When the ultraviolet light or sunlight irradiation is lost, it returns to the original color material. In this embodiment, the material of the functional layer 30 is photochromic ink.

[0025] The beneficial effect of the suitcase shell of the present utility model having a color-changing function under visible light is that by setting the functional layer 30 and the bearing layer 40, the functional layer 30 is coated on the bearing layer 40 and combined with the outer side surface of the inner layer 20 by hot pressing. The functional layer 30 can be photosensitive and color-changing, realizing the diversification of the color of the box shell, improving the attraction to consumers. Moreover, the bearing layer 40 adopts a transparent structure, which can not only display the visual effect of the photosensitive color change of the functional layer 30, but also protect the functional layer 30 to ensure the use effect of the product, and has strong practicability.

[0026] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered to be within the scope described in this specification.

[0027] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
