[0027] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 9 As shown, the present embodiment provides a remote control with a side-emitting light panel assembly, comprising: a housing 1, a PCB circuit board 2, a light guide 3, a black light-shielding film 4, a transparent silicone key 5 and a plastic key 6, wherein the PCB circuit board 2, the light guide 3, the black light-shielding film 4, the transparent silicone key 5 and the plastic key 6 are sequentially arranged in the housing 1 from bottom to top; at least two groups of side-emitting LED lights 7 are arranged on the PCB circuit board 2, a foam mounting portion 8 is arranged between each two adjacent groups of LED lights 7, and a filling foam 9 is arranged in the foam mounting portion 8, so that The filling foam 9 is arranged in the foam mounting portion 8 and between the PCB circuit board 2 and the light guide 3; the black light shielding film 4 is provided with a light-transmitting perforation 401, and the positions of the light-transmitting perforations 401 correspond to the positions of the LED lights 7, the transparent silicone buttons 5 and the plastic buttons 6, respectively, that is, each of the light-transmitting perforations 401 is matched with a corresponding LED light 7, transparent silicone buttons 5 and plastic buttons 6, respectively, so as to achieve light transmission at the positions of each button, and the LED light 7 is arranged on the inner side of the transparent silicone buttons 5. The light guide 3 can be made of PET board, that is, polyethylene terephthalate plastic board. The side-emitting light board assembly refers to a light board structural member including side-emitting LED lights 7, and each group of side-emitting LED lights 7 corresponds to a button module.

[0029] It should be noted that if the foam is simply set, during the use of the remote control, due to shaking and other reasons, the actual use effect will be affected due to problems such as the misalignment of the foam. At the same time, it is not conducive to the regional control of the product's luminous effect.

[0030] In the present embodiment, at least two groups of side-emitting LED lamps 7 are arranged on the PCB circuit board 2. In practical applications, each group of side-emitting LED lamps 7 can be controlled separately. A foam mounting portion 8 is arranged between each two adjacent groups of LED lamps 7. A filling foam 9 is arranged in the foam mounting portion 8. The filling foam 9 is preferably black foam. The filling foam 9 is arranged in the foam mounting portion 8 and between the PCB circuit board 2 and the light guide 3, thereby effectively preventing the filling foam 9 from being misaligned. The structure is simple, stable and reliable. On this basis, the black light-shielding film 4 in the present embodiment is provided with a light-transmitting perforation 401. The positions of the light-transmitting perforations 401 correspond to the positions of the LED lamps 7, the transparent silicone buttons 5 and the plastic buttons 6, respectively, so that light can be transmitted at the positions corresponding to each button and light shielding can be achieved at other positions, so as to cooperate with the filling foam 9 to more effectively avoid the occurrence of light crosstalk between different groups of LED lamps, that is, to avoid the light crosstalk problem between different button modules in the prior art, and the light-emitting effect is uniform.

[0031] More preferably, the foam mounting portion 8 of this embodiment is preferably a recessed mounting portion, and the filling foam 9 is fixedly arranged in the recessed mounting portion through an adhesive layer. That is, a recessed mounting portion (such as a groove) is arranged between every two adjacent groups of LED lights 7 on the PCB circuit board 2, and the filling foam 9 is pasted in the recessed mounting portion, so as to better achieve the positioning and limiting function of the filling foam 9. The filling foam 9 of this embodiment is compressed and arranged between the PCB circuit board 2 and the light guide 3, that is, the filling foam 9 is arranged in an interference type, so as to further ensure the effect of anti-cross-lighting.

[0032] like Figure 2 and Figure 3 The foam mounting portion 8 of the embodiment shown in the figure includes at least two mounting structures of different shapes, and the shapes of the filling foam 9 are matched with the corresponding shapes of the foam mounting portion 8. Such a design of the embodiment, on the one hand, can well realize different shape designs for key modules in different areas to fully guarantee the anti-cross-light effect; on the other hand, it can also realize fool-proof design, and the required shape of the filling foam 9 can be quickly distinguished by the shape of the foam mounting portion 8 to improve assembly efficiency.

[0033] like Figure 3 As shown, the side of the LED lamp 7 in this embodiment is provided with light guide film dots 10, and the depth of the light guide film dots is 0.02mm-0.05mm, so as to better achieve the light guiding effect between the light guide sheet 3. The light guide film dots 10 can also be called light guide film dots or light guide plate dots in the industry.

[0034] like Figure 4As shown, the surface of the transparent silicone key 5 described in this embodiment is provided with a first spray layer, and the first spray layer includes a black oil layer and a white oil layer from top to bottom, and a first laser-engraved light-transmitting area is provided above the white oil layer of the first spray layer, that is, the white oil layer and the black oil layer are sprayed on the front of the transparent silicone key 5 in sequence, and then laser engraving is performed on the surface of the transparent silicone key 5 to obtain the first laser-engraved light-transmitting area, and the shape of the first laser-engraved light-transmitting area is consistent with the second laser-engraved light-transmitting area 604 described later, so as to leak out the white bottom of the white oil layer and achieve the light-transmitting effect, and prevent the problems of cross-light and uneven light emission. The thickness of the white oil layer and the black oil layer on the front of the transparent silicone key 5 is preferably 0.4mm~0.6mm.

[0035] like Figure 5 , Figure 6 and Figure 8 As shown, similarly, the surface of the plastic button 6 in this embodiment is provided with a second spray coating layer, and the second spray coating layer is provided with a second laser-engraved light-transmitting area 604 .

[0036] In one implementation of this embodiment, Figure 7 and Figure 8 As shown, the second spray layer of this embodiment includes the first UV ink layer 601, the first black oil layer 602 and the first white oil layer 603 from top to bottom, that is, the white white oil layer is first sprayed on the surface of the plastic key 6, and then the black oil layer and the UV ink layer are sprayed, and finally the surface is laser engraved, and the first white oil layer 603 is leaked, and the white background characters can be leaked through the second laser engraving light-transmitting area 604 to achieve a light-transmitting effect. In this embodiment, the total thickness of the first UV ink layer 601, the first black oil layer 602 and the first white oil layer 603 is preferably between 1.2mm and 1.8mm, and the thickness of the first white oil layer 603 does not exceed one third of the total thickness. The thickness of the first UV ink layer 601 and the thickness of the first black oil layer 602 are kept consistent as much as possible to achieve processing and avoid the problem of excessive requirements for laser engraving equipment.

[0037] In another implementation of this embodiment, Figure 8 and Fig. 9As shown, the bottom surface of the plastic key 6 in this embodiment is provided with a third spray layer, and the third spray layer includes a second white oil layer 605 and a second UV ink layer 606 from top to bottom; the second spray layer includes a second black oil layer 607. Such a design can also achieve the effect of leaking white background characters and light transmission in the second laser engraving light-transmitting area 604 after the second black oil layer 607 is laser engraved. In this embodiment, since the second white oil layer 605 and the second UV ink layer 606 are arranged on the bottom surface (i.e., the inner side) of the plastic key 6, there is no fear of affecting the white oil layer, which can reduce the control accuracy requirements for laser engraving and reduce equipment costs. It is worth noting that in this embodiment, the thickness of the second spray layer and the thickness of the third spray layer are both 0.8mm-1.0mm, which should not be too thick or too thin, so as to keep the same thickness as much as possible, so that the light transmission effect can reach the best state, and on the basis of preventing cross-light, it also effectively achieves a uniform and soft light transmission effect.

[0038] The specific implementation methods described above are preferred implementation methods of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the shape and structure of the present utility model are within the protection scope of the present utility model.
