Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is an exploded view of a switchgear according to an embodiment of the present disclosure, and fig. 2 is a schematic partial structural diagram of the switchgear shown in fig. 1. The switching device 000 may include: the light guide structure includes a main board 100, a case 200, a switch panel 300, a light source 400, and a light guide structure 500.

The main board 100 in the switchgear 000 may be fixed inside the housing 200 in the switchgear 000.

The switch panel 300 of the switch device 000 may be located outside the case 200 and connected to the case 200 and the main board 100, respectively.

The light source 400 and the light guide structure 500 in the switch device 000 are fixed outside the housing 200, and the light source 400, the light guide structure 500 and the switch panel 300 may be distributed on the same side of the housing 200. The light source 400 may be electrically connected to the main board 100, and the light emitting surface 401 of the light source 400 faces the light guiding structure 500. Note that the light guide structure 500 is not shown in fig. 2 for clarity of other structures.

Referring to fig. 3, fig. 3 is a schematic position diagram of a portion of the structure shown in fig. 1. The orthographic projection of the light source 400 on the housing 200 is not coincident with the orthographic projection of the light guide structure 500 on the housing 200.

For example, the switch device 000 in the embodiment of the present application may be integrated in a wall switch system, an operator may trigger the switch panel 300 once, and the main board 100 controls the electric devices in the wall switch system to switch to the working state after receiving a work starting instruction triggered by the switch panel 300; the operator triggers the switch panel 300 again, and the main board 100 controls the electrical equipment in the wall switch system to switch to the work-stopping state after receiving the work-stopping instruction triggered by the switch panel 300.

In the embodiment of the present application, the light source 400 and the light guide structure 500 may be disposed in the switch device 000, and the light emitted from the light source 400 can be guided out of the switch device 000 through the light guide structure 500. Thus, the switching device 000 not only has the function of realizing the on-off of the circuit, but also has the function of a small night lamp, so that an operator can conveniently control the switching device 000 under the condition of low external light. Therefore, the functions of the switch device 000 are effectively enriched, and different use requirements can be met. For example, the Light source 400 may be a mini-LED (mini-LED).

It should be noted that, when the orthographic projection of the light source 400 on the housing 200 does not coincide with the orthographic projection of the light guiding structure 500 on the housing 200, the light source 400 is a side-in light source, and the light emitted by the light source can make the whole light guiding structure 500 emit light outwards under the light guiding effect of the light guiding structure 500, so that the area of the light emitting surface of the switching device 000 is large when the switching device 000 is in the small night light function, and the effect of the switching device 000 is good when the switching device 000 is in the small night light function.

In summary, the switch device provided in the embodiments of the present application may include: mainboard, casing, flush mounting plate of switch, light source and light-directing structure. The light source, the light guide structure and the switch panel are all distributed on one side of the shell of the switch device, the switch panel is connected with the shell and the mainboard, and the light source is electrically connected with the mainboard. Light emitted by the light source can be well guided out through the light guide structure. So, switching device not only has the function of realizing the circuit break-make, can also have the function of little night-light, and the operating personnel of being convenient for controls switching device under the lower condition of external light. Like this, effectual abundant switching device's function can satisfy different user demands.

Optionally, please refer to fig. 4, and fig. 4 is a schematic diagram illustrating a light guide plate and a light source according to an embodiment of the present disclosure. The light guide structure 500 in the switch device 000 may be a light guide sheet 500a, and the light emitting surface 401 of the light source 400 may face the side surface a1 of the light guide sheet 500 a. In this case, the light emitted from the light source 400 is guided to the side surface a1 of the light guide sheet 500a, and the light is guided in the light guide sheet 500a and emitted from the front surface b1 (i.e., the surface facing away from the housing 200) of the light guide sheet 500a, so that the brightness of the emitted light is high.

It should be noted that, one surface of the light guide plate 500a close to the housing 200 has a plurality of dots, and after the light emitted from the light source 400 is incident into the light guide plate 500a, the light can be totally reflected between the upper bottom surface and the lower bottom surface of the light guide plate 500a for a plurality of times. After the light totally reflected between the upper bottom surface and the lower bottom surface is emitted to the dots, the dots can reflect the light and emit the light from the front surface of the light guide sheet 500a, so that each position of the light guide sheet 500a can emit light outwards. Moreover, the dot density distributed at a certain position of the light guide sheet 500a is inversely related to the distance between the position and the light source 400, so that the intensity of the light emitted outwards from each position of the light guide sheet 500a is relatively uniform.

It should be further noted that, because the light guide plate 500a has the characteristics of good light emitting effect and high light intensity, in the actual use process, a smaller number of LED lamps can be used to achieve a better light emitting effect. Therefore, the number of the LED lamps in arrangement is saved, and the power consumption is saved. For example, one LED or two LEDs may be used, which is not specifically limited in the embodiments of the present application. In other implementations, the light guide structure 500 may also be a light guide pillar or a light guide film.

In the embodiment of the present application, please refer to fig. 5, and fig. 5 is a schematic view illustrating another light guide sheet and a light source according to the embodiment of the present application. The side of the light guide 500a may have a reflection film a1, and the reflection film a1 may have a light passing hole a2 corresponding to the light source 400, so that light emitted from the light source 400 may be directed to the light guide 500a through the light passing hole a 2. In this case, by providing the reflection film a1 on the side surface a1 of the light guide sheet 500a, the light emitted from the light source 400 is emitted to the light guide sheet 500a through the light passing hole a2 of the reflection film a1, and then the light is prevented from being emitted from the side surface a1 of the light guide sheet 500 a. That is, the light is transmitted in the light guide sheet 500a as much as possible and emitted from the front side b1 of the light guide sheet 500a, thereby improving the utilization rate of the light emitted from the light source 400.

Alternatively, as shown in fig. 4 and 5, the light guide plate 500a may have a ring shape, and the reflective film a1 may include: the first sub-reflective film a11 and the second sub-reflective film a12, the first sub-reflective film a11 may be located on an outer side surface of the light guide plate 500a, the second sub-reflective film a12 may be located on an inner side surface of the light guide plate 500a, and at least one of the first sub-reflective film a11 and the second sub-reflective film a12 may have a light passing hole a 2. In this way, the light emitted from the light source 400 is guided by the annular light guide sheet 500a, and the light emission effect of the light guide sheet 500a can be further improved. The whole front surface of the switch device 000 can show a luminous effect, and the switch device 000 can be well decorated. For example, when the light source 400 is located at the outer side of the light guide plate 500a, the first sub-reflection film a11 corresponding to the light source 400 may have a light passing hole a2, and the second sub-reflection film a12 located at the inner side of the light guide plate 500a may not have a light passing hole a 2. The light emitted from the light source 400 can be emitted to the light guide sheet 500a through the light passing hole a 2; when the light source 400 is located on the inner side of the light guide plate 500a, the second sub-reflective film a12 corresponding to the light source 400 may have a light hole a2, and the first sub-reflective film a11 located on the outer side of the light guide plate 500a may not have a light hole. The light-passing holes a2 may be formed in both the first sub-reflection film a11 and the second sub-reflection film a12, which is not specifically limited in the embodiments of the present application. When the number of the light sources 400 is plural, the light sources 400 may be distributed in a ring shape, so that the light beams emitted from the plural light sources 400 can be uniformly incident on the ring-shaped light guide plate. In other possible implementations, the light guide sheet 500a may be a whole surface structure, and when the light guide sheet 500a is a whole surface light guide sheet, the light guide sheet 500a may be disposed on the switch panel 300.

In other realizable manners, the first sub-reflective film a11 may be disposed only on the outer side surface of the light guide plate 500a, and when the light source 400 is located on one side of the first sub-reflective film a11, the first sub-reflective film a11 needs to be provided with a light through hole a 2; when the light source 400 is located at the inner side of the light guide plate, the first sub-reflective film a11 may not have the light passing hole a 2. In addition, the second sub-reflective film a12 may be provided only on the inner surface of the light guide sheet 500a, and when the light source 400 is located on the side of the second sub-reflective film a12, the second sub-reflective film a12 may be provided with a light passing hole a 2; when the light source 400 is located at the side of the outer side surface of the light guide plate 500a, the second sub-reflective film a12 may not have the light passing hole a 2. The embodiment of the present application does not specifically limit this implementation manner.

In the embodiment of the present application, please refer to fig. 6 and 7, fig. 6 is an exploded schematic view of another switch device provided in the embodiment of the present application, and fig. 7 is a structural schematic view of the switch device shown in fig. 6. The switching device 000 may further include: a protective cover 600, the protective cover 600 being connectable to the housing 200. A first receiving cavity 601 may be formed between the protective cover 600 and the housing 200, and the light source 400, the light guide structure 500 and the switch panel 300 of the switch device 000 are located in the first receiving cavity 601. The light guide structure 500 may be bonded to a side of the protective cover 600 close to the housing 200. The light source 400 may be fixed at a side of the switch panel 300 facing away from the housing 200. In this case, the protective cover 600 can prevent dust, moisture, and the like from entering the inside of the switching device 000, thereby providing a good protective effect on the internal structure of the switching device 000. For example, the light guide structure 500 may be adhered to a side of the protective cover 600 close to the housing 200 by a back adhesive.

Alternatively, the protective cover 600 in the switch device 000 may be a transparent glass cover, and a side of the protective cover 600 close to the housing 200 may have a semi-transparent coating (not shown in the figure). In this case, the translucent coating layer is provided on the transparent glass cover plate on the side close to the housing 200, thereby further modifying the front surface of the switching device 000. In addition, after light emitted from the light source 400 is guided by the light guide structure 500, the light can be transmitted to the external environment through the protective cover 600. Thus, when the intensity of the light in the external environment is low, the light transmitted by the light source 400 can accurately provide the position of the switch device 000 for the operator, and a better use experience is brought. In the present application, the protective cover 600 may be a panel made of tempered glass, and the shape of the protective cover 600 may be rectangular or circular. The semi-light-transmitting coating on the side of the protective cover 600 adjacent to the case 200 may be a coating formed of black paint. Therefore, the protective cover plate made of the toughened glass can play a good role in decorating the appearance of the switch device. It should be noted that the semi-transparent coating can also be a coating made of paint of other colors.

In the embodiment of the present application, as shown in fig. 6, the switching device 000 may further include: the light sensor 700, the light sensor 700 is fixed outside the housing 200, and the light sensor 700 can be electrically connected to the main board 100 in the switch device 000. Wherein, the motherboard 100 may be configured to: the intensity of the external light is detected by the light sensor 700 to control the light source 400 to switch to the light emitting state or to the light stopping state according to the intensity of the external light. In this case, the light sensor 700 can automatically detect the light in the external environment, and the main board 100 in the switch device 000 can automatically adjust the intensity of the light emitted by the light source 400 according to the intensity of the light. Therefore, the power consumption of the light source 400 can be effectively saved, and better use experience is achieved. For example, when the light sensor 700 detects the intensity of the external light, it can be converted into an electrical signal, and the electrical signal is detected through the motherboard 100, so as to detect the intensity of the light received by the light sensor 700. The intensity of the light emitted by the light source 400 may be inversely related to the intensity of the external light. That is, when the main board 100 detects that the intensity of the external light is high, the intensity of the light emitted by the light source 400 can be controlled to be low; when the main board 100 detects that the intensity of the external light is low, the intensity of the light emitted by the light source 400 can be controlled to be high.

Optionally, please refer to fig. 8, and fig. 8 is a schematic structural diagram of another switching device provided in the embodiment of the present application. The switching device 000 may further include: a light source switch 800 on a side of the case 200, and the light source switch 800 may be electrically connected to the light source 400 and the main board 100, respectively. Wherein, the motherboard 100 may be configured to: after receiving a light-on command triggered by the light source switch 800, controlling the light source 400 to switch to a light-emitting state; after receiving a light-off command triggered by the light source switch 800, the light source 400 is controlled to switch to a light-off state. In this application, the light source switch 800 may be integrated in the switch device 000, and when the light source 400 needs to be controlled to emit light, an operator may hold the switch device 000 by hand and trigger the light-on command and the light-off command through the light source switch 800 on the switch device 000 to control the operating state of the light source 400. For example, an operator may press light source switch 800 once, so that light source switch 800 may trigger a light source turn-on command; once again, the operator presses light source switch 800 so that light source switch 800 can trigger a light source turn-off command.

In the actual use process, the operating state and the stop operating state of the light source 400 can be switched by means of wireless control. For example, a smart gateway may be disposed in the switch device 000, and a terminal device (e.g., a mobile phone APP) may be wirelessly connected to the smart gateway, so as to switch between an operating state and a stop operating state of the light source through the terminal device.
