DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The utility model relates to a luminous button, comprising a light-transmitting member 100, a pressing plate 200 and a base 300. The luminous button can be used as a control device for various products, such as lamps, smart toilets, smart cabinets and other products.

[0033] like Figure 4 and Figure 5 As shown, the main body of the light-transmitting member 100 can be in the shape of a rectangular disk, a square disk, a circular disk, etc., but is not limited thereto. The light-transmitting member 100 as a whole can be made of a light-transmitting plastic material or a silicone material, etc. In the direction shown in the figure, the lower side of the light-transmitting member 100 is the light-inlet side 110, and the upper side is the light-outlet side 120. A light-emitting rib plate 130 is provided on the light-outlet side 120, and the light-emitting rib plate 130 protrudes upward from the surface of the light-outlet side 120. A light-inlet side 110 is provided with a light-guiding portion 140, and the light-guiding portion 140 protrudes downward from the surface of the light-inlet side 110. The shape of the light-guiding portion 140 is not limited, and can be set to the same shape as the light-emitting rib plate 130, or can be set to a plate shape, a block shape, a strip shape, etc. The light-emitting rib plate 130 and the light-guiding portion 140 are aligned up and down, mainly for transmitting light between the light-emitting rib plate 130 and the light-guiding portion 140. As shown Figure 1 , Figure 2 and Figure 3As shown, the pressing plate 200 is movably mounted on the light-emitting side 120. The pressing plate 200 can move relative to the light-emitting side 120 by lifting, rotating, flipping, etc. The number of the pressing plates 200 can be one or more. The convex rib surrounds the pressing plate 200. The convex rib surrounds the pressing plate 200 in the following manner: Figure 1 The convex rib shown is wrapped around the pressing plate 200 to form a closed loop; or it is an open loop along the circumference of the pressing plate 200, etc. The light-transmitting member 100 is installed on the base 300, and the light-incoming side 110 of the light-transmitting member 100 faces the base 300. The base 300 covers the light-incoming side 110, and the light-guiding portion 140 extends into the base 300. A lamp module 400 is installed in the base 300. The lamp module 400 can be an LED lamp bead 410, a light bar, etc. The light source of the lamp module 400 is directed toward the light-guiding portion 140 for illumination, and the light penetrates the light-guiding portion 140 from the light-incoming side 110 toward the light-outgoing side 120 and enters the light-emitting rib plate 130, and then the light is projected outward through the light-emitting rib plate 130. The base 300 covers the light-incoming side 110, and the push plate 200 is equivalent to covering the light-outgoing side 120 after being installed on the light-outgoing side 120. The push plate 200 and the base 300 are made of opaque materials, and the two sides of the main body of the light-transmitting member 100 can only let in light through the light-guiding portion 140 and let out light through the light-emitting rib plate 130. The light-emitting rib plate 130 and the light-guiding portion 140 are integrally formed on the light-transmitting member 100. With the installation position of the push plate 200 and the base 300 coordinated, the light generated by the lamp module 400 can only be transmitted to the light-emitting rib plate 130 through the light-guiding portion 140, so that the light-incoming and light-outgoing positions of the light-transmitting member 100 are more concentrated, making full use of the light, and there is no need to use the high-cost process of shielding spraying on the light-transmitting member 100, effectively reducing the production cost.

[0034] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, a plurality of light guiding portions 140 are provided on the light-incoming side 110 of the light-transmitting member 100, and the light guiding portions 140 are spaced apart in sequence along the direction of the light-emitting rib plate 130. The light guiding portion 140 is in the shape of a trapezoidal table, and in the direction shown in the figure, the vertical cross-section of the light guiding portion 140 is a trapezoidal cross-section. The lower base of the trapezoidal cross-section is away from the light-incoming side 110, and the upper base is close to the light-incoming side 110. The size of the lower base is smaller than the size of the upper base, and the lower base is defined as the short side 141, and the upper base is defined as the long side 142. The two side edges connected between the long side 142 and the short side 141 are hypotenuses 143. The linear extension lines of each hypotenuse 143 toward the light-incoming side 110 will pass through the light-emitting rib plate 130, and the extension lines of adjacent hypotenuses 143 between two adjacent light guiding portions 140 intersect, and the intersection point is located on the light-emitting rib plate 130. The lamp module 400 includes a plurality of lamp beads 410, and the lamp beads 410 are preferably LED lamp beads 410. Figure 3As shown, a lamp bead 410 is aligned with a short side 141. The lamp bead 410 shines toward the short side 141, and the light enters the light guide part 140 from the side where the short side 141 is located, and the light is scattered in the light guide part 140. Part of the light is projected into the light-emitting rib plate 130 along the direction of the hypotenuse 143. Since the adjacent hypotenuses 143 of the two light guide parts 140 intersect in the light-emitting rib plate 130, part of the light can intersect in the light-emitting rib plate 130, and the light can completely cover the light-emitting rib plate 130, and no dark area (non-luminous area) will be generated on the ribs, so that the light-emitting effect of the light-emitting rib plate 130 is uniform. Preferably, the point where the extension lines of the adjacent hypotenuses 143 of the two light guide parts 140 intersect is located on the end face of the light-emitting rib plate 130 away from the light-incoming side 110, that is, in the direction shown in the figure, the intersection is located on the upper end face of the light-emitting rib plate 130. This makes the light-emitting effect on the light-emitting rib plate 130 more uniform.

[0035] Furthermore, the surface where the short side 141 of the light guide 140 is located is set as a serrated surface 144. When light is irradiated on the serrated surface 144, the light is fully refracted by the serrated surface 144, making the illumination area wider, and the trapezoidal shape is matched to fully ensure the coverage of the light when it is transmitted to the light-emitting rib plate 130.

[0036] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 6 As shown, the base 300 includes a first bracket 310. The first bracket 310 is made of an opaque material. A sink 311 is provided on the first bracket 310. In the direction shown in the figure, the sink 311 sinks downward on the upper surface of the first bracket 310. The shape of the sink 311 is adapted to the shape of the light-incoming side 110. A first plug hole 312 is provided on the sink 311. The light-incoming side 110 is placed in the sink 311, and the periphery of the sink 311 is used to position the periphery of the light-incoming side 110. The light-guiding portion 140 is passed through the first plug hole 312. The size of the first plug hole 312 is set according to the light-guiding portion 140. The sink 311 is used to position the light-transmitting member 100 when it is installed on the first bracket 310, and on the other hand, the upper surface of the sink 311 is used to cover and block light from the light-incoming side 110. The first plug hole 312 protects the light guide portion 140 from air, and the hole wall of the first plug hole plays a certain light guiding role for the light guide portion 140 .

[0037] Further, such as Figure 1 , Figure 2 and Figure 3As shown, the base 300 also includes a second bracket 320 and a bottom shell 330. The second bracket 320 and the bottom shell 330 are both made of opaque materials. The first bracket 310 and the bottom shell 330 are connected to each other, and an installation cavity is defined between the first bracket 310 and the bottom shell 330. The first bracket 310 and the bottom shell 330 can be fixed to each other by buckling or screw locking. The second bracket 320 is installed between the first bracket 310 and the bottom shell 330, and the bottom shell 330 can be set in a box shape with an upper opening. The second bracket 320 can be set in a cover plate shape, and the second bracket 320 covers the upper opening of the bottom shell 330. The second bracket 320 divides the installation cavity into a first cavity 301 and a second cavity 302. It can be that the first cavity 301 is defined between the first bracket 310 and the second bracket 320, and the second cavity 302 is defined between the second bracket 320 and the bottom shell 330. The second bracket 320 is provided with a second insertion hole 321, which is opposite to the light guide 140. The light guide 140 sequentially passes through the first insertion hole 312, the first cavity 301 and the second insertion hole 321 to extend into the second cavity 302. The lamp module 400 is installed in the second cavity 302 to illuminate the end of the light guide 140 extending into the second cavity 302. Light is generated in the second cavity 302, which is blocked by the second bracket 320 and the bottom shell 330, and the light is gathered at the end of the light guide 140 and transmitted toward the light output side 120.

[0038] In a further embodiment of the present invention, Figure 2 , Figure 3 and Figure 7 As shown, a button 500 is installed in the second cavity 302. A soft rubber pad 600 is installed on the surface of the second bracket 320 located in the first cavity 301. The soft rubber pad 600 can be made of materials such as silicone and rubber. A first pressing column 210 is provided on the pressing plate 200. A second pressing column 510 is provided on the button 500. The second pressing column 510 vertically passes through the second bracket 320 upward and abuts on the soft rubber pad 600. The first pressing column 210 vertically passes through the light-transmitting member 100 and the first bracket 310 downward and extends into the first cavity 301, and the bottom end of the second pressing column 510 abuts on the soft rubber pad 600, and the lower end of the first pressing column 210 and the upper end of the second pressing column 510 are aligned with each other. The pressing plate 200 moves in a lifting manner relative to the light-transmitting member 100, and the button 500 is a spring-pressed control electrical component. When the pressing plate 200 is pressed, the pressing plate 200 drives the first pressing column 210 to move downward in the axial direction, and then pushes the second pressing column 510 to move downward, and performs a pressing operation on the button 500. The button 500 can be reset upward through the internal elastic member, and the pressing plate 200 is reset upward through the first pressing column 210. One pressing plate 200 is used in conjunction with one button 500. The soft rubber pad 600 is blocked between the first pressing column 210 and the second pressing column 510, and the soft rubber pad 600 seals the position where the second pressing column 510 passes through the second bracket 320.

[0039] Specifically, Figure 3 and Figure 7 As shown, the soft rubber pad 600 is provided with a boss 610 protruding toward the first bracket 310. The interior of the boss 610 is hollow. The bottom end of the first pressing column 210 abuts against the upper side of the boss 610, and the boss 610 has an upward elastic supporting force on the first pressing column 210. The upper end of the second pressing column 510 extends into the interior of the boss 610. When an external force presses down on the pressing plate 200, the first pressing column 210 descends, and the boss 610 elastically deforms downward, thereby pushing the second pressing column 510 downward. When the external force is lost, the boss 610 elastically resets upward, pushing the first pressing column 210 upward to reset, and at the same time keeping the pressing plate 200 in the raised position without being affected by external force.

[0040] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the pressing plate 200 is provided with a clamping head 220 and a limiting column 230. The clamping head 220, the limiting column 230 and the first pressing column 210 extend downward on the lower side of the pressing plate 200. The first bracket 310 is provided with a clamping hole 313, a sinking platform 314 and a limiting platform 315, and the sinking platform 314 and the limiting platform 315 sink toward the direction where the second bracket 320 is located. The light-transmitting member 100 is provided with a first avoidance hole 150, a second avoidance hole 160 and a connecting column 170. The limiting column 230 can pass through the first avoidance hole 150 and extend into and abut against the limiting platform 315. When the pressing plate 200 is pressed down, the relative position of the limiting platform 315 and the limiting column 230 can limit the pressing stroke of the pressing plate 200, and at the same time, the cooperation of the limiting column 230 and the first avoidance hole 150 has a certain guiding effect on the lifting and lowering of the pressing plate 200. The connecting column 170 is inserted and fixed in the sink 314, and the connecting column 170 and the sink 314 can be interlocked by screws, so as to fix the light-transmitting member 100 and the first bracket 310. The end of the clamp 220 can be set in a barb shape, and the clamp 220 can pass through the second avoidance hole 160 and be clamped on the clamp hole 313. When the pressing plate 200 is pressed down, the clamp 220 can move downward with the pressing plate 200; when the pressing plate 200 is reset upward, the clamp 220 is clamped on the clamp hole 313, thereby limiting the pressing plate 200 from completely separating upward from the light-transmitting member 100.

[0041] In some specific embodiments of the present invention, Figure 2 As shown, the button 500 and the light module 400 are integrated on the circuit board 700, and the circuit board 700 is installed in the second cavity 302. The second cavity 302 is separated from the first cavity 301, and plays a sealing and protective role for the circuit board 700.

[0042] The utility model also relates to a smart toilet cover, which is applied with the above-mentioned luminous button. The luminous button is connected to the electric control core board in the smart toilet cover, and the start and stop of the electrical components such as the heating mechanism and the water washing mechanism inside the smart toilet cover are controlled by pressing the button. The luminous button has a lower production cost than the existing similar devices, which can reduce the overall cost of the smart toilet cover. At the same time, the light effect of the button can well assist the user in using it in the case of dim light in the external environment.
