Detailed Description

The advantages and features of the present invention and methods of accomplishing the same will be understood more readily by reference to the following detailed description of exemplary embodiments and accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1 and fig. 2a together, fig. 1 is a flow chart of the manufacturing process of the housing structure according to the present invention; fig. 2a is a schematic flow chart of the manufacturing of the shell structure according to the first embodiment of the present invention. First, a translucent housing 10 is provided, the translucent housing 10 has a first surface 101 and a second surface 102 opposite to each other (step S101), in step S101, the translucent housing 10 can be made of a light guide material with full light transmission or semi-light transmission, for example: ABS resin (ABS), Polycarbonate (PC) or acryl.

Next, a first light shielding layer 11 is formed on the second surface 102 (step S102), and in step S102, the paint is disposed on the second surface 102 by spraying to form the first light shielding layer 11 on the second surface 102. The coating material for forming the first light-shielding layer 11 may be: a rubber coating, a Polyurethane (PU) coating, or a combination thereof.

Next, the engraved groove 1021 uncovered by the first light-shielding layer 11 is formed on the second surface 102 (step S103), and in step S103, the engraved groove 1021 penetrating through the first light-shielding layer 11 is formed on the second surface 102 by laser engraving. The engraved groove 1021 may display a pattern under light irradiation, and the pattern may be: graphics, text, numbers, symbols, or combinations thereof.

Next, a second light shielding layer 12 is formed on the first surface 101 (step S104), and in step S104, the paint is disposed on the first surface 101 by spraying to form the second light shielding layer 12 on the first surface 101. The coating material for forming the second light-shielding layer 12 may also be: a rubber coating, a polyurethane coating, or a combination thereof.

Finally, the protective layer 13 is formed on the second light shielding layer 12 (step S105), and in step S105, the paint is sprayed on the second light shielding layer 12 to form the protective layer 13 on the second light shielding layer 12. The coating material used to form the protective layer 13 is a photocurable coating material, for example: ultraviolet light curing coating (Ultraviolet curing coating). In the present embodiment, the thicknesses of the second light-shielding layer 12 and the passivation layer 13 are both between 15 μm and 40 μm, and the light transmittance can be controlled by adjusting the thicknesses of the second light-shielding layer 12 and the passivation layer 13.

Referring to fig. 1 and fig. 2b together, fig. 2b is a schematic flow chart illustrating a second embodiment of manufacturing a housing structure according to the present invention. The steps S101, S102 and S103 corresponding to fig. 2b are the same as those in fig. 2a, and are not repeated herein. However, the difference from fig. 2a is that after the second light-shielding layer 12 of step S104 is completed, a third light-shielding layer 14 may be further formed on the second light-shielding layer 12. Finally, a passivation layer 13 is formed on the surface of the third light-shielding layer 14. The third light-shielding layer 14 coating may also be: rubber coating, polyurethane coating or combination thereof, and the thickness thereof is between 15 μm and 40 μm.

Referring to fig. 3, fig. 4a and 4b, and fig. 5a and 5b together, fig. 4a and 5a are enlarged views of a region a in fig. 3; fig. 4b and 5b are schematic top view diagrams of hidden or displayed patterns of an electronic device. In fig. 3, the electronic device 1 is a mouse, and the holding end of the housing 10 has an engraved groove 1021. A light emitting module 20 is disposed inside the electronic device 1, and the light emitting module 20 is used for projecting an internal light IL to a position where the engraved groove 1021 is disposed. In this embodiment, the light emitting module 20 may be: a light emitting diode module, an organic light emitting diode, a quantum dot light emitting diode module, or an electroluminescent module. In addition, the ambient environment of the electronic device 1 may also generate an external light SL, which is irradiated to the outer surface of the housing 10.

Referring to fig. 4a, when the external light SL is irradiated to the position where the engraved groove 1021 is located, the external light SL is absorbed by the second light-shielding layer 12 and cannot penetrate through the engraved groove 1021 for reflection. Therefore, in a state where the light emitting module 20 inside the electronic device 1 is turned off, the external light SL cannot reflect the pattern formed by the engraved groove 1021 (as shown in fig. 4 b), and the visual effect of hiding the pattern can be achieved.

Referring to fig. 5a, when the light emitting module 20 disposed inside the electronic device 1 on the side of the second surface 102 is turned on, and the internal light IL2 generated by the light emitting module is projected to the disposed region of the non-engraved groove 1021, the internal light IL2 is absorbed by the first light shielding layer 11 and the second light shielding layer 12, and cannot pass through the housing 10 of the electronic device 1. On the other hand, when the generated internal light IL1 is projected to the position of the engraved groove 1021, since the position of the engraved groove 1021 has only one second light-shielding layer 12, and since the intensity of the light source of the internal light IL1 is greater than that of the external light SL, the internal light IL1 can penetrate through the housing 10 of the electronic device 1 by refraction, and the pattern formed by the engraved groove 1021 is displayed at the holding end of the housing 10 (as shown in fig. 5 b), thereby achieving the visual effect of displaying the hidden pattern. Although the present invention only proposes the embodiment of the electronic device 1 as a mouse, in practical applications, the housing structure provided by the present invention can also be applied to a keyboard, a screen, a desktop computer, a notebook computer, a tablet, a personal digital assistant, a smart phone, a game machine, a printer, a business machine or a scanner, even a general household appliance, and is not limited to the embodiment presented in the present invention. In addition, the light emitting module 20 provided by the present invention can be in a single-color or multi-color light emitting mode, or a combination of a plurality of light emitting units, so that when the light emitting module 20 is in a multi-color light emitting mode or a combination of a plurality of light emitting units, the generated internal light IL can cause the engraved groove 1021 to display a colorful hidden pattern at the same time, or the hidden pattern to perform color conversion.

Compared with the prior art, the shell structure with the hidden pattern provided by the invention can hide the pattern arranged on the shell structure when the internal light source of the electronic device is turned off, so that the aesthetic feeling of the appearance consistency of the electronic device can be maintained. When the internal light source of the electronic device is turned on, the hidden pattern can be further displayed on the surface of the shell structure of the electronic device, so that the electronic device has both identification and special visual effect; therefore, the present invention is a creation with great industrial value.

The invention may be modified in various ways by anyone skilled in the art without however departing from the scope of the appended claims.
