Description

Technical Field

[0001] The utility model relates to the field of wall switches, in particular to a switch with an indicator light and a light-guiding structure. Background Art

[0002] At present, wall switches on the market usually need to be installed in conjunction with a base box. The base box is embedded in the wall, and the wall switch is fixed to the front side of the base box by two screws on the left and right. The above screws are hidden. For example, the cover plate of the "A Wall Switch" with the Chinese Utility Model Patent Publication No. CN211578597U is formed with two connecting countersunk holes for connecting to the base box; therefore, the wall switch needs to be provided with a structure to avoid the above screws, so that the switch function parts of the wall switch are arranged between the two above screws on the left and right, so the space available for the switch function parts is small. However, the larger the area of the switch button of the wall switch, the easier it is for the user to successfully press the switch button, and it is also conducive to the wall switch to achieve a borderless visual effect. (i.e. the switch button covers the above-mentioned cover plate), so that the user can only see the switch button in front of the wall switch, which is conducive to the simple appearance of the wall switch; some wall switches are provided with indicator lights to make a certain part of the switch button illuminated, as mentioned above, but due to the need to arrange the above-mentioned connecting countersunk holes, the light source of the indicator light is not convenient to be arranged in the corresponding range of the above-mentioned connecting countersunk holes. If the wall switch is provided with two or more switch buttons, the indicator light is not convenient to be centered on the switch button in the left and right directions, that is, the luminous part on the switch button is not convenient to be centered in the left and right directions, or in other words, the luminous part on the switch button cannot be flexibly arranged, which is not conducive to improving the visual effect of the wall switch. Therefore, it is necessary to improve the above-mentioned wall switch. Summary of the Invention

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] The utility model has a light guide structure with an indicator light switch, such as Figures 1 to 4 As shown, it includes a switch button 1, a cover plate 2 and a bottom shell assembly 7. The front end of the bottom shell assembly 7 is connected to the cover plate 2. The switch button 1 is hinged to the cover plate 2. The hinge axis of the switch button 1 and the cover plate 2 extends in the left and right directions, so that the switch button 1 can swing to realize the switch switching function; Figure 2 and Figure 3As shown, the cover plate 2 is formed with a bottom box connection hole 201. Figures 4 to 8 As shown, the switch with indicator light having a light guide structure of the present invention further includes a light source 601, which is arranged at the rear side of the corresponding switch button 1. Figure 1 As shown in FIG. 1 , a light hole 1001 is formed on the switch button 1. For example, Figure 1 As shown, the switch of the present invention can be a double switch, that is, the number of switch buttons 1 is set to two, and the two switch buttons 1 are arranged side by side on the left and right, so the width dimension of the switch button 1 in the left-right direction is smaller than the length dimension of the switch button 1 in the up-down direction, and the light hole 1001 can be a long hole extending in the up-down direction, so that the light hole 1001 is more compatible with the shape of the switch button 1.

[0028] like Figures 3 to 8 As shown, the switch with an indicator light having a light guide structure of the present invention further includes a light guide member 3 for guiding the light emitted by the light source 601 to the light through hole 1001. The light guide member 3 is arranged on the rear side of the corresponding switch button 1. Specifically, the light emitted by the light source 601 (partially) irradiates one end of the light guide member 3, and the light changes direction through the light guide member 3 and can be emitted to the light through hole 1001. As a result, the light source 601 can be offset relative to the light through hole 1001, and the layout position of the light source 601 and the light through hole 1001 can be flexibly set, such as Figure 5 As shown, the light source 601 can avoid the bottom box connection hole 201, as shown in FIG. Figure 1 As shown, the light hole 1001 can be arranged in the center of the corresponding switch button 1 in the left-right direction, and the two switch buttons 1 are combined in parallel to cover the cover plate 2, which is conducive to making the switch have a neat and simple visual effect; as can be seen from the above, the utility model is conducive to improving the visual effect of the switch.

[0029] For example, the light guide 3 may be an optical fiber. Figure 8 As shown, the switch button 1 can be embedded with a light-transmitting member 11 , which is made of light-transmitting plastic. The light-transmitting member 11 fills the light-through hole 1001 to prevent debris from entering the light-through hole 1001 .

[0030] Furthermore, if Figure 8 and Figure 9As shown, the light guide 3 includes a light guide plate portion 31, which is arranged between the light source 601 and the switch button 1. A light incident surface 301 is formed at one end of the light guide 3. The position of the light incident surface 301 corresponds to the light source 601. The light incident surface 301 can be approximately perpendicular to the front-to-back direction. A light emitting surface 302 is formed at the other corresponding end of the light guide 3. The position of the light emitting surface 302 corresponds to the light through hole 1001. The light emitting surface 302 can be parallel to the light incident surface 301. A light incident reflecting surface 311 for reflecting light incident on the light incident surface 301 into the light guide plate portion 31 is formed at one end of the light guide plate portion 31. A light emitting reflecting surface 312 for reflecting light passing through the light guide plate portion 31 to the light emitting surface 302 is formed at the other corresponding end of the light guide plate portion 31. Figure 8 The dotted arrows in the figure schematically represent the light path. Specifically, the light emitted forward by the light source 601 is approximately perpendicular to the light incident surface 301, so the refraction effect of the light at the light incident surface 301 is low, and the light enters the light guide 3 and then reaches the light incident reflection surface 311. After the reflection effect of the light incident reflection surface 311, the light is reversed by approximately 90 degrees. Figure 8 In the figure, the light turns to the left, propagates in the light guide plate portion 31, and then reaches the light-emitting reflective surface 312. It can also be understood that the light-incident reflective surface 311 is used to emit light to the light-emitting reflective surface 312, and the light-emitting reflective surface 312 changes the light to the forward direction by approximately 90 degrees, so that the light passes through the light-emitting surface 302 and is emitted forward. Since the position of the light-emitting surface 302 corresponds to the light-through hole 1001, the above-mentioned light can pass through the light-through hole 1001 and be emitted to the front of the switch button 1, so that the user can see the light at the position of the light-through hole 1001. Specifically, the light guide 3 can be made of transparent plastic, such as Figure 9 As shown, a first chamfer is formed at the right front end of the light guide plate portion 31, and the light incident reflection surface 311 is specifically the inner surface of the first chamfer; a second chamfer is formed at the left rear end of the light guide plate portion 31, and the light output reflection surface 312 is specifically the inner surface of the second chamfer. During this period, part of the light is allowed to pass through the light incident reflection surface 311 or the light output reflection surface 312 and refract to the outside of the light guide 3; through the above arrangement, it is beneficial to simplify the optical path structure of the light guide 3 (the light only needs to be reversed twice), which is beneficial to making the light guide 3 easy to manufacture, and because the light guide plate portion 31 is a plate-like structure, the light output surface 302 is easy to be made into a rectangle, so that the light output surface 302 is better matched with the long strip-shaped light hole 1001.

[0031] Furthermore, if Figure 10As shown, a positioning boss 101 and a first buckle block 102 are formed on the rear side of the switch button 1, and the positioning boss 101 is relatively plugged into the light guide 3, that is, a plug-in through-hole is formed on the light guide 3, and the positioning boss 101 is adapted to be connected with the corresponding plug-in through-hole, and the first buckle block 102 buckles the edge of the light guide 3. Therefore, during the assembly process, the plug-in through-hole is aligned with the positioning boss 101, and then the light guide 3 is moved forward. In the process of the positioning boss 101 being relatively inserted into the plug-in through-hole, the upper and lower ends of the light guide 3 respectively pass forward over the corresponding first buckle blocks 102, and then the first buckle block 102 buckles the edge of the light guide 3, so that the light guide 3 and the switch button 1 are assembled simply and quickly.

[0032] Furthermore, if Figures 3 to 5 As shown, the switch of the present invention further includes a driving member 4 and a light source circuit board 6. The front of the driving member 4 is hinged to the bottom shell assembly 7. The driving member 4 belongs to the prior art. For example, reference can be made to the Chinese utility model patent publication number CN221466483U "A swing-type contact structure of a switch and a switch having the structure". Figure 6 As shown, the light source 601 is provided on the light source circuit board 6, and the light source 601 is configured as an LED lamp bead, and a plurality of LED lamp beads are arranged roughly in the up and down direction; Figure 11 As shown, the front end of the driving member 4 is formed with a mounting groove 401. Figure 5 and Figure 6 As shown, the light source circuit board 6 is adapted to be mounted in the corresponding mounting groove 401. In other words, the shape of the mounting groove 401 matches the outer shape of the light source circuit board 6, thereby positioning the light source circuit board 6. Aligning the switch button 1 with the driver 4 facilitates swinging the switch button 1 and driving the corresponding driver 4. Therefore, embedding the light source circuit board 6 in the front end of the driver 4 facilitates alignment of the light source 601 with the switch button 1, which helps simplify the optical path structure of the light guide 3.

[0033] Furthermore, if Figure 3 and Figure 8 As shown, a circuit board protection cover 5 is provided in the mounting groove 401, and the circuit board protection cover 5 is provided on the front side of the light source circuit board 6. Figure 12 As shown, a light-through slot 501 is formed on the circuit board protection cover 5. Figure 8 As shown, the position of the light-through slot 501 corresponds to the light source 601, so the light emitted forward by the light source 601 can pass through the light-through slot 501 and reach the light incident surface 301. Figure 8 As shown, the circuit board protection cover 5 blocks the light source circuit board 6 from shifting forward. Specifically, as shown in FIG. Figure 11 As shown, a second buckle block 4011 is formed on the driving member 4 , and the second buckle block 4011 is buckled with the edge of the circuit board protection cover 5 .

[0034] For example, the light source circuit board 6 is electrically connected to the static contact of the switch. When the user presses the switch button 1, the switch button 1 drives the corresponding driving member 4 to swing, and the driving member 4 drives the moving contact of the switch to move until it is in conductive contact with the static contact, so that the light source circuit board 6 is connected to the mains power, and the light source 601 is lit.

[0035] like Figure 13 and Figure 14 As shown, in some embodiments, the switch can be a triple switch, with the switch buttons 1 located on the left and right sides of the switch respectively, and a middle button is provided between the left and right switch buttons 1. Since the middle button is arranged in the center, the middle button does not need to be provided with a corresponding light guide.
