[0030] As mentioned above, some existing switches have LED lights on the buttons to indicate the position of the switch through the light of the LED lights. However, switches with LED lights on the buttons still have some disadvantages. The emitted light is relatively dazzling in the dark, which is uncomfortable, and may directly shine into the user's eyes, seriously affecting the user experience of the switch.
[0031] A new switch device is provided in an embodiment of the present application. The button and the light-emitting module of the switch device are respectively located on both sides of the mounting cover plate. At least part of the light emitted by the light-emitting module is transmitted to the diffuser plate through the light-guiding element. The diffuser plate diffuses the received light and irradiates it to the outside of the switch device. The diffusion effect of the diffuser plate can make the light received by the diffuser plate more dispersed, thereby making the light emitted by the diffuser plate softer. In addition, under the cover of the button, the light emitted by the diffuser plate will not directly hit the human eye. The user can find the position of the switch device according to the halo on the wall where the switch device is located. Compared with the switch device with LED lights set on the existing buttons, the user experience is greatly improved.
[0032] It should be noted that the various drawings in the specification of this application are only used to facilitate the explanation and understanding of the present embodiment, and are not intended to be any limitation to the present application, and are not necessarily drawn according to the actual scale.
[0033] The following is combined with Figure 1-5 The switch device 100 provided in the embodiment of the present application is described in detail.
[0034] Figure 1 is a schematic diagram of a switch device 100 provided in an embodiment of the present application. The switch device 100 is mainly used to control the switching of various lamps. Figure 1 and Figure 2 It can be seen that the switch device 100 includes a button 110, a switch function module 120, a mounting cover 130, a light emitting module 140, a light guide module 150, and the like.
[0035] The button 110 and the switch function module 120 are respectively arranged on both sides of the mounting cover 130. The button 110 is used to drive the switch function module 120 to perform a switch action after being triggered. The mounting cover 130 may be provided with a through hole. The through hole on the button 110 mounting cover 130 contacts the switch function module 120, so as to drive the switch function module 120 to perform a switch action after the button 110 is triggered. It should be understood that the switch function module 120 is a module that controls the switch inside the switch to be turned on or off. Its specific structure can refer to the relevant technology, and will not be repeated here, and it is all within the protection scope of the embodiments of the present application.
[0036] The number of buttons 110 and switch function modules 120 in the embodiment of the present application is not limited. For example, the control switch can be a single-key control switch, a double-key control switch, a three-key control switch, or a four-key control switch as shown in the accompanying drawings, all of which are within the protection scope of the embodiment of the present application.
[0037] The light emitting module 140 and the switch function module 120 are arranged on the same side of the mounting cover 130. The light guide module 150 includes a diffuser 151 and a light guide element 152, wherein the diffuser 151 is arranged at the edge of the mounting cover 130, and the light guide element 152 is connected to the diffuser 151. It should be understood that the light emitting module 140 may include various suitable light sources for emitting light, and the power supply of the light emitting module 140 may be the power supply connected to the switch device 100, or may be an additional power supply, all of which are within the protection scope of the embodiments of the present application.
[0038] Specifically, the light emitting module 140 is used to emit light when the switch function module 120 is turned off. It should be understood that the switch function module 120 being turned off corresponds to the electronic device controlled by the switch device 100 being in a power-off state, that is, when the switch device 100 is used to control a lamp, the light emitting module 140 emits light when the lamp is powered off. In the embodiment of the present application, the light emitting module 140 is preferably configured not to emit light when the switch function module 120 is turned on, so that when the lamp controlled by the switch device 100 emits light, the light emitting module 140 is turned off to reduce a portion of the power consumption of the switch device 100. The control structure for controlling the light emitting module 140 to turn on can be driven by the button 110 or by the switch function module 120. The specific structure of the control structure for turning on the light emitting module 140 can refer to the relevant technology, which will not be described in detail here, and all are within the protection scope of the embodiment of the present application.
[0039] The light guide element 152 is used to transmit at least part of the light emitted by the light emitting module 140 to the diffuser 151 . The light guide element 152 can be directly connected to the light emitting module 140 or adjacent to the light emitting module 140 with a certain gap, both of which are within the protection scope of the embodiments of the present application.
[0040] The diffusion plate 151 is used to diffuse the received light to the outside of the switch device 100, so as to indicate the position of the switch through the diffused light. In order to enhance the diffusion effect of the diffusion plate 151, the light-emitting side of the diffusion plate 151 can be set to be more blurred, and some impurities can be added to the diffusion plate 151, so that the light is more dispersed under the reflection effect of the impurities.
[0041] Through the diffusion effect of the diffusion plate 151, the light from the light emitting module 140 can be dispersed more, making the light emitted by the diffusion plate 151 softer, which can significantly improve the user experience. Figure 1 , Figure 3 and Figure 4 As shown, the diffuser 151 is arranged at the edge of the mounting cover 130. When actually used, the light emitted by the diffuser 151 to the outside of the switch device 100 will not directly hit the human eye under the obstruction of the button 110, but will hit the wall of the switch device 100. The user can indirectly find the position of the switch device 100 according to the halo of the wall. It should be understood that the light-guiding part of the light-guiding element 152 and the diffuser 151 can be made of transparent glass, plastic, or other suitable materials, all of which are within the protection scope of the embodiments of the present application.
[0042] In the embodiment of the present application, the button 110 and the light emitting module 140 are respectively located on both sides of the mounting cover 130, and at least part of the light emitted by the light emitting module 140 is transmitted to the diffuser 151 through the light guiding element 152. The diffuser 151 diffuses the received light and irradiates it to the outside of the switch device 100. Through the diffusion effect of the diffuser 151, the light received by the diffuser 151 can be made more dispersed, so that the light emitted by the diffuser 151 is softer; in addition, under the shielding of the button 110, the light emitted by the diffuser 151 will not directly hit the human eye, and the user can find the position of the switch device 100 according to the halo on the wall where the switch device 100 is located. Compared with the switch device 100 with an LED light set on the existing button 110, the user experience is greatly improved.
[0043] In some optional embodiments, the light emitting module 140 includes at least two light emitting units 141, and the light guiding element 152 includes at least two light guiding channels 1521, and the light guiding channels 1521 correspond to the light emitting units 141 one by one. It should be understood that the light emitting unit 141 is a light emitting element such as an LED lamp, and the light guiding channel 1521 is used to conduct at least part of the light emitted by the light emitting unit 141 to the diffuser 151.
[0044] In the embodiment of the present application, by means of at least two light-emitting units 141 and light-guiding channels 1521 corresponding one to the light-emitting units 141, the diffuser plate 151 can receive light at multiple positions, so that the light can be more dispersed. Moreover, by evenly arranging the light-emitting units 141 and the light-guiding channels 1521 at intervals, the light in the diffuser plate 151 can be made more uniform, thereby enhancing the diffusion effect of the diffuser plate 151.
[0045] In some optional embodiments, the light emitting unit 141 is electrically connected to the connection terminal of the switch device 100, so as to supply power to the light emitting unit 141 through the connection terminal. Figure 2 As shown, a plurality of wire connectors 142 are provided below the light emitting module 140, and the light emitting unit 141 can be electrically connected to the wiring terminal of the switch device 100 through the wire connector 142, so as to realize power supply to the light emitting unit 141 through the wiring terminal. It should be noted that, in order to match the rated voltage of the light emitting unit 141, the light emitting unit 141 can be electrically connected to the wiring terminal of the switch device 100 through an appropriate transformer. The specific circuit configuration can refer to the relevant technology, which will not be described here, and is within the protection scope of the embodiment itself. In the embodiment of the present application, the light emitting unit 141 can be powered by the wiring terminal of the switch device 100, and there is no need to set up an additional power supply, which avoids the operation of replacing the additional power supply, making the use of the switch device 100 more convenient.
[0046] like Figure 2 As shown, in some optional embodiments, the light guide element 152 further includes a connector 1522, and the light guide channels 1521 are connected by the connector 1522. It should be understood that, corresponding to the connector 1522, a space for accommodating the connector 1522 should be reserved in the switch device 100 to facilitate the installation of the connector 1522. In the embodiment of the present application, multiple light guide channels 1521 can be connected together by the connector 1522 to enhance the integrity and structural strength of the light guide element 152, and can facilitate the installation of the light guide element 152.
[0047] In some optional embodiments, the switch device 100 also includes an internal cover plate 160, which is connected to the switch function module 120 and is arranged on the same side of the installation cover plate 130 as the switch function module 120; a limiting structure 161 is provided on the internal cover plate 160, and the limiting structure 161 is located between the light-emitting unit 141 and the light-guiding channel 1521, and the relative position between the light-emitting unit 141 and the light-guiding channel 1521 can be limited by the limiting structure 161.
[0048] like Figure 3As shown, a housing space for accommodating the switch function module 120 and the light emitting module 140 is formed between the bottom shell 170 of the switch device 100 and the mounting cover plate 130, and an internal cover plate 160 connected to the switch function module 120 is also provided in the housing space, and the switch function module 120 can be fixed by the internal cover plate 160. A limiting structure 161 corresponding to the light emitting module 140 is provided on the internal cover plate 160, and the limiting structure 161 is located between the light emitting unit 141 and the light guiding channel 1521. The relative position between the light emitting unit 141 and the light guiding channel 1521 can be limited by the limiting structure 161, so as to prevent the light guiding channel 1521 from being separated from the light emitting unit 141, thereby ensuring the light guiding channel 1521 conducts the light emitted by the light emitting unit 141.
[0049] like Figure 5 As shown, in some optional embodiments, a shading plate 162 is further provided on the inner cover plate 160, and the shading plate 162 is located between adjacent light-emitting units 141. It should be understood that the shading plate 162 is made of an opaque material, and the specific material selection can refer to the relevant technology, which will not be repeated here, and all are within the protection scope of the embodiments of the present application. Furthermore, two adjacent shading plates 162 can also be used to form a shading groove, and different shading grooves are placed around different light-emitting units 141, thereby enhancing the shading effect of the light-emitting unit 141.
[0050] In the embodiment of the present application, the shading plate 162 can prevent mutual interference between the light emitted by each light emitting unit 141, so that the light emitted by each light emitting unit 141 can be transmitted through the corresponding light guiding channel 1521 as much as possible, thereby reducing the loss of light transmission.
[0051] like Figure 4 As shown, in some optional embodiments, the mounting cover 130 is provided with a plurality of first channels 131 connected to the diffuser plate 151 ; different light guide channels 1521 are connected to the diffuser plate 151 through different first channels 131 .
[0052] In the embodiment of the present application, each light guiding channel 1521 is at least partially located in the corresponding first channel 131, and different light guiding channels 1521 are connected to the diffuser plate 151 through different first channels 131. Therefore, through the first channel 131, on the one hand, the position of the light guiding channel 1521 can be fixed, and on the other hand, different light guiding channels 1521 can be separated, so that the diffuser plate 151 can receive light from multiple positions, thereby improving the utilization rate of the diffuser plate 151 and giving full play to the diffusion effect of the diffuser plate 151.
[0053] like Figure 3As shown, in some optional embodiments, a light incident surface 1524 is provided at the first end of the light guiding channel 1521 , and the light incident surface 1524 is opposite to the light emitting unit 141 and perpendicular to the central axis of the light emitting unit 141 .
[0054] In the real-time example of the present application, the light incident surface 1524 of the first end of the light guiding channel 1521 is opposite to the light emitting unit 141 and perpendicular to the central axis of the light emitting unit 141, so that the light incident surface 1524 directly faces the front of the light emitting unit 141, and most of the light emitted by the light emitting unit 141 can enter the light guiding channel 1521, thereby improving the utilization efficiency of the light emitting unit 141.
[0055] In some optional embodiments, the second end of the light guide channel 1521 is provided with a light emitting surface 1523, and the light emitting surface 1523 is connected to the diffuser 151, and the light transmitted by the light guide channel 1521 can be transmitted to the diffuser 151 through the light emitting surface 1523. In the real-time example of the present application, the light emitting surface 1523 is separately provided at the second end of the light guide channel 1521, and the light guide channel 1521 can be separated from the diffuser 151, that is, the light guide channel 1521 and the diffuser 151 can be separately provided, which can make the setting of the light guide channel 1521 and the diffuser 151 more flexible. Of course, as another implementation method, the conducting channel and the diffuser 151 can also be integrated, which is within the protection scope of the embodiments of the present application.
[0056] like Figure 2 and Figure 3 As shown, in some optional embodiments, the light guiding channel 1521 is provided with a reflective bevel 1525, which is located on the convex side of the turning point of the light guiding channel 1521; the reflective bevel 1525 is used to reflect the light transmitted by the light guiding channel 1521 at the turning point of the light guiding channel 1521 to change the direction of the light transmitted by the light guiding channel 1521.
[0057] In the embodiment of the present application, a reflective slope 1525 is provided on the convex side of the turning point of the light guide channel 1521. The reflective slope 1525 can reflect the light transmitted by the light guide channel 1521 to change the direction of the light transmitted by the light guide channel 1521, so that the light transmitted by the light guide channel 1521 can turn at the turning point of the light guide channel 1521 along the direction in which the light guide channel 1521 extends, thereby ensuring the light transmission effect of the light guide channel 1521.
[0058] The angle between the reflective bevel 1525 and the straight segments on both sides of the turning point of the light guide channel 1521 is preferably complementary to 1 / 2 of the turning angle of the light guide channel 1521. Exemplarily, when the turning angle of the light guide channel 1521 is 90°, the angle between the reflective bevel 1525 and the straight segments on both sides of the turning point of the light guide channel 1521 is preferably 45°, so that the angle between the light in the light guide channel 1521 and the corresponding part of the light guide channel 1521 before and after reflection by the reflective bevel 1525 is consistent, so that the light in the light guide channel 1521 can be guided more smoothly.
