Description

Electronics with anti-spill function

The present application is related to an indicator light on an electronic device, in particular to an electronic device with an anti-splash function.

Electronic devices (such as notebook computers, tablet computers, or monitors) are more or less provided with indicator lights to let users know the current status of the electronic device, such as an indicator light that the power is turned on or that the device is processing.

In the known design, a light guide is arranged between the light outlet and the light-emitting element. Therefore, when the light-emitting element emits light, the light is emitted from the light outlet through the light guide of the light guide, thus achieving the function of an indicator light.

However, when at least two groups of indicator lights are arranged on the electronic device and are adjacent to each other, the light guides between the light emitting elements and the light outlet holes will interfere with each other, which has been criticized for a long time.

Therefore, how to design an electronic device with an anti-overlight function to improve the above-mentioned deficiencies in the prior art is a major problem that the creators of the present application want to solve.

The purpose of the present application is to provide an electronic device with anti-spill function, which can prevent two adjacent light guide bars from interfering with each other through the light shield.

In order to achieve the above object, the present application provides an electronic device with an anti-spill function, comprising: a device housing with at least two perforations and a protruding structure corresponding to the at least two perforations. The protruding structure is provided with a first fixing member; at least two light guide columns; and a light-emitting end exposed from each of the light-shielding cylinders, each of the light-shielding cylinders corresponds to each of the light-incoming ends to form an accommodating space, the second fixing member of the light-shielding cover is fixed corresponding to the first fixing member, and each of the light-emitting ends corresponds to each of the perforations;

Compared with the prior art, the present application has the following effects: before the light emitted by each light-emitting element exits from each perforation, there will be no overflow at all, so it has the effect of preventing each light guide column from overflowing and interfering with each other.

The detailed description and technical content of the application are described below with the accompanying drawings, but the attached drawings are only for reference and description, and are not intended to limit the application.

The present application provides an electronic device with an anti-splash function, as shown in FIG. 2 , which is mainly applied to any electronic device with an indicator light on the device housing 1 .

As shown in FIGS. 1 to 3 , the electronic device with anti-splash function (hereinafter referred to as the electronic device) of the present application includes: a device housing 1 , a circuit board 2 , at least two light guide columns 3 and a light shield 4 .

The device case 1 can be a case of any electronic device, such as a case of a notebook computer, a case of a tablet computer or a case of a monitor, which is not limited in the present application. The device housing 1 is provided with at least two through holes 12 adjacent to each other. In this embodiment, three through holes 12 are provided as an example for illustration. The device housing 1 is also provided with a protruding structure 11 corresponding to all the perforations 12, and the protruding structure 11 is provided with a first fixing member 111; it should be noted that the present application does not limit how the device housing 1 protrudes to provide the protruding structure 11, and the protruding structure 11 in this embodiment is described by taking an integral extension from an inner shell surface 13 of the device housing 1 as an example.

Each light guide column 3 can be a column of any shape, as shown in the figure, it is a cylinder, which is not limited in this application. The light guide column 3 has a light incident end portion 31 and a light output end portion 32 opposite to each other.

The light shield 4 is injection-molded outside all the light-guiding columns 3 by means of injection molding. The shading cover 4 has a second fixing member 41 and includes three shading cylinders 42 integrally connected with each other. Each shading cylinder 42 wraps around each light guide column 3 (wrapping: wrapping only around the cylinder surface of the light guide column 3), so that the light-emitting end 32 of each light-guiding column 3 is exposed from one end of each light-shielding cylinder 42, and each light-shielding cylinder 42 forms an accommodating space (see FIG. 3 ) S corresponding to each light-incoming end 31.

Combine the light shield 4 together with all the light guide columns 3 in the device housing 1, and fix the light shield 4 together with all the light guide columns 3 to the device housing 1 by fixing the second fixing member 41 corresponding to the first fixing member 111, and make each light-emitting end portion 32 correspond to each through hole 12.

Three light emitting elements 21 adjacent to each other are disposed on a surface 22 of the circuit board 2 . The circuit board 2 and the cover-shaped device housing 1 are fixed to each other, so that the light emitting elements 21 are correspondingly located in the aforesaid accommodating spaces S, and the shading cover 4 is sandwiched between the inner shell surface 13 of the device housing 1 and the board surface 22 of the circuit board 2 . It should be noted that, in one embodiment, the shading cover 4 can be made of an elastic material (for example: thermoplastic elastomer (TPE)), so that the shading cover 4 can elastically abut (or be elastically sandwiched) between the inner shell surface 13 and the board surface 22; as for the fixing of the circuit board 2 and the device housing 1 (not shown in the figure), many fixing elements can first pass through the circuit board 2 and then be fixed to the fixing posts of the device housing 1, but this application is not limited to this.

Thereby, as shown in FIG. 3 , since the shading cover 4 is sandwiched between the inner shell surface 13 of the device housing 1 and the board surface 22 of the circuit board 2 , and each light-emitting element 21 and each light guide column 3 are jointly shielded by each light-shielding tube 42 , therefore, the light of each light-emitting element 21 enters from the light-incident end 31 of each light-guiding column 3 and exits from the light-emitting end 32. The gap and leaks from the gap between the light shield 4 and the plate surface 22, so the light emitted by each light emitting element 21 will not have any overflow light before it exits each through hole 12, so that the light guide columns 3 will not interfere with each other. It should be noted that each through-hole 12 of the device casing 1 can emit the light emitted from each light-emitting element 21 , thus forming the above-mentioned plurality of indicator lights (component symbols are not indicated).

Specifically, as shown in FIG. 3 , the light incident end 31 of each light guide column 3 retracts from the other end of each light-shielding cylinder 42 , and the light-emitting end 32 of each light guide column 3 protrudes from the aforementioned one end of each light-shielding cylinder 42 and is plugged into each through hole 12 . The shading cover 4 has a first abutting side 401 and a second abutting side 402 elastically abutting against the inner shell surface 13 and the plate surface 22 respectively. Each light-emitting end 32 is exposed from the first abutting side 401. Each light-shielding tube 42 has a deformation section T corresponding to the second abutting side 402. The cylinder inner wall 422 of each deformation section T is formed from the first abutting side 401 toward the second abutting side 402. out of shape. Wherein, the aforesaid accommodating spaces S are formed between each light-incident end portion 31 and the cylinder inner wall 422 of each light-shielding cylinder 42 .

Therefore, when the circuit board 2 and the device casing 1 are fixed to each other so that the shading cover 4 is elastically sandwiched between the inner shell surface 13 and the board surface 22, the deformation section T of each light shielding tube 42 will be elastically deformed (for example, it can be slightly flattened due to pressure), so that the second abutting side 402 of the shading cover 4 can conform to the board surface 22, so as to achieve a better light-shielding effect.

In order to control the minimum value of the distance D between the light guide columns 3 at 0.3mm to meet the requirements of today's electronic devices for thinness and shortness, each light guide column 3 can be injection molded first, and then all the light guide columns 3 are covered in the light shield 4 by double-material encapsulation (or double-material injection), so as to reduce the distance between the light guide columns 3 . As shown in FIG. 1, each light-shielding tube 42 has an injection hole 421 due to the use of double-material encapsulation (or double-material buried injection), and all injection holes 421 of the light shield 4 can be blocked by the protruding structure 11 to prevent light from leaking from the injection hole 421. It should be noted that the protruding structure 11 can be a four-side light-shielding wall (not shown in the figure) or a single-side light-shielding wall as shown in FIG.

As for the aforesaid first fixing member 111 and second fixing member 41, there can be various feasible fixing methods, as shown in Fig. 1 and Fig. 3 , and in this embodiment, the following example will be described. The first fixing member 111 and the second fixing member 41 respectively include at least one buckle body 411 (such as a buckle body 411 with an inverted buckle function) and at least one buckle hole 1111. The number of buckle bodies 411 and buckle holes 1111 is two as shown in the figure, and each buckle body 411 corresponds to each buckle Button hole 1111 buckle.
