Referring to FIG. 1 to FIG. 3, there are shown schematic structural views of the side light emitting structure 100 in different viewing angles according to an embodiment of the present invention. In this embodiment, the side light emitting structure 100 is used for side mounting and luminous lighting of the device installed with the structure. It includes an upper cover 110, a rear cover, and is erected between the upper cover 110 and the rear case 120 The metal side 130, the connection between the metal side 130 and the upper cover 110 and the back cover is seamlessly designed to prevent liquid from flowing in and dust from entering the side light emitting structure 100. In order to simultaneously transmit the light emitted by the light emitting unit inside the side light emitting structure 100 to the outside of the side light emitting structure 100, the side light emitting structure 100 is mainly composed of the following components:

-Hole 131

At a certain position of the metal side 130, for example, a hole 131 is opened in the middle of the metal side 130 along the length of the metal side 130. The hole 131 can be formed into a strip shape, a wave shape, a dot shape, a step shape, etc. Various shapes. The opening of the slot 131 will no longer completely close the metal side 130, and the accommodating space formed between the upper cover 110 and the rear case 120 will communicate with the outside through the slot 131. At the same time, the hole 131 is also provided as a light exit path of the light emitting unit in the side light emitting structure 100, and the user can observe the light emitted by the light emitting unit outside the side light emitting structure 100.

-The first filler 132

Since the slot 131 is opened on the metal side 130, but it is not suitable for keeping the fully open state at all times, the electronic components in the accommodating space formed between the upper cover 110 and the rear case 120 are exposed to the external space. Therefore, the hole 131 will be filled with light-transmissive plastic. On the one hand, the hole 131 is closed to maintain the structural consistency of the side light-emitting structure 100. On the other hand, it can replace the part of the original metal side 130 to replace the light-emitting unit The outgoing light is transmitted to the outside. Specifically, the inner wall of the slot 131 is first partially filled with the first filling glue 132 as a boundary between the metal side 130 and the plastic, and is completely injection-molded around the inner wall of the slot 131, so that the first filling glue 132 has a ring shape. The joint of the first filling glue 132 and the inner wall of the slot 131 is completely fit, so that after the injection of the first filling glue 132 is completed, the metal inner wall portion of the slot 131 no longer faces the external space, but is filled by the first The glue 132 instead communicates with the external space.

-Second filling glue 133

Since the first filling glue 132 only partially fills the hole 131, a second filling glue 133 is injection molded in the middle of the annular first filling glue 132. Different from the first filling glue 132, the second filling glue 133 includes an integrally formed filling portion 134 and a supporting portion 135. The filling portion 134 contacts the first filling glue 132 and fills the space enclosed by the first filling glue 132. The double-layer structure composed of the filling portion 134 forming the first filling glue 132 and the second filling glue 133 closes the hole 131, and the supporting portion 135 extends toward the accommodating space and is used to support electronic devices and light guides in the accommodating space effect.

Through the setting of the first filling glue 132, the second filling glue 133 no longer directly contacts the metal side 130. For those skilled in the art, it is extremely difficult to fit metal and plastic seamlessly and tightly in the injection molding process. Therefore, in the design of many side light-emitting structures 100, the hole 131 needs to be equipped with a plastic Clamping fixed structure. In the present invention, the slot 131 can no longer be designed with a similar structure. The first filler 132 serves as a transition layer, and one side is completely attached to the metal inner wall of the slot 131. Then the second filler 133 needs to be attached when injection molding The object made of metal is the first filling part 134 which is also plastic, which greatly reduces the difficulty of injection molding. Based on this, the first filling glue 132 can be nano-injected to ensure a tight bond with the metal inner wall of the slot 131 and maintain the appearance of the junction with the slot 131 when the metal is anodized.

-Lighting components

In order to achieve the effect that the side light-emitting structure 100 can emit light, a light-emitting component is fixedly mounted on the support portion 135. After the light-emitting component can be installed on the support portion 135 by snapping, bonding, etc., the light-emitting component is supported by the support portion 135 It is supported inside the side light emitting structure 100, that is, in the accommodating space formed by the upper cover 110 and the rear case 120. The light-emitting component emits light after being powered by the power supply, and the light is first emitted to the second filling glue 133, and part of the light is directly emitted through the second filling glue 133, and the other part penetrates the second filling glue 133 to the first filling glue 132, and the 132 is emitted, or all of the second filler 133 is emitted.

After having the above configuration, on the user side, the first filling glue 132 and the second filling glue 133 provided at the slit 131 can be observed outside the side light emitting structure 100 to have a light effect after the light is emitted, and this embodiment is installed The devices in the side light emitting structure 100, such as smart terminals and display devices, can provide interactive lighting effects on the side.

And it can be understood that, when the second filling glue 133 is uniformly injection-molded, it can ensure that the light emission is also in a uniform state, and will not cause light leakage or visually uncomfortable experience to the user. Therefore, in a preferred embodiment, the first filler 132 is formed by nano-injection molding, and the second filler 133 is uniformly transparent plastic. More specifically, the first filler 132 is firstly solid injection molded, and is laid on the inner wall of the hole 131, and then the CNC (CNC machine tool) is used to make the first filler 132 of nano-injection as thin as possible, reducing the side of the metal 130 appearance influence.

Referring to FIGS. 2-4, in a preferred embodiment, the light-emitting assembly includes a flexible circuit board 142 (FPC) and at least one LED lamp 140 electrically connected to the flexible circuit board 142. As the core of the light-emitting unit of the light-emitting component, the LED emits light after receiving power from a power source (such as a battery of an intelligent terminal) through the flexible circuit board 142. Correspondingly, the smart terminal may also include a control unit that controls the current to control the lighting timing, lighting duration, lighting frequency, etc. of the LED lamp 140 to provide a better interactive experience for the user. On the supporting portion 135, the end surface facing the light emitting assembly is a supporting surface, and a mounting groove 136 for mounting the LED lamp 140 is provided on the supporting surface, and the concave direction of the mounting groove 136 faces the direction facing away from the LED lamp 140, then the mounting groove 136 The released space can be used to support the LED lamps 140, and each LED lamp 140 extends into the installation groove 136 and is fixedly arranged. The installation groove 136 can be used to fix the position of the LED lamp 140 on the one hand, to prevent the electronic device from colliding with each other between the upper cover 110 and the rear case 120, and on the other hand, to reduce the space occupied by the light-emitting assembly and the support portion 135, Furthermore, the thickness of the smart terminal, display device, etc. having the side light emitting structure 100 is compressed.

Further preferably or optionally, the light-emitting assembly further includes at least one grounding elastic sheet 141, and the grounding elastic sheet 141 is arranged opposite to the LED lamp 140, and is arranged on the flexible circuit board 142 in a different plane, that is, the LED lamp 140 is arranged on the flexible circuit The end surface of the board 142 facing the mounting groove 136, and the grounding elastic piece 141 are provided on the end surface of the flexible circuit board 142 facing away from the mounting groove 136. When the ground dome 141 is provided, it is electrically connected to the LED lamp 140 through the circuit of the flexible circuit board 142. At the same time, in order to cooperate with the ground dome 141, a metal bracket 150 is also provided between the upper cover 110 and the light-emitting assembly. The metal stand 150 can also be extended along the length of the flexible circuit board 142, so that the ground dome 141 faces the metal stand 150. When the setting of the metal bracket 150 and the ground elastic piece 141 is completed, the relative positional relationship between the metal bracket 150 and the ground elastic piece 141 is configured such that the metal bracket 150 contacts the ground elastic piece 141 and squeezes the ground elastic piece 141 to slightly flatten it. Thereby, a conduction path of the LED lamp 140-the ground dome 141-the metal bracket 150 is formed, and the ground end is manufactured for the LED lamp 140.
