[0030] See Figures 1-7The utility model provides a kind of light-emitting switch 100, by setting up light groove 2221 above light-emitting piece 31 to converge light, draw near light source point, make light source more close to light-transmitting place, to make light more bright and uniform, to improve the prompting function and appearance texture of light-emitting switch 100 in this way.

[0031] Please see Figures 1-3 In one embodiment, the light-emitting switch 100 includes a switch assembly 30 and a housing assembly 20, the switch assembly 30 includes a light-emitting piece 31, and the housing assembly 20 includes a light-transmitting unit 22, which is disposed on one side of the light-emitting piece 31. The side of the light-transmitting unit 22 away from the light-emitting piece 31 is provided with a light-transmitting area. The side of the light-transmitting unit 22 close to the light-emitting piece 31 is configured with a light groove 2221, which corresponds to the position of the light-emitting piece 31. The groove wall of the light groove 2221 can gather the light emitted by the light-emitting piece 31 into the light groove 2221 and then conduct it to the light-transmitting area.

[0032] In this way, due to the structural characteristics of the arc-shaped groove wall of the light groove 2221, the light emitted by the light-emitting piece 31 will be folded back and gathered into the light groove 2221 after encountering the groove wall. The light that has been refocused and gathered forms a new light source, which is closer to the light-transmitting unit 22 than the light-emitting piece 31. Therefore, the light emitted from the light-transmitting unit 22 will be brighter and more uniform, and the light effect will be better.

[0033] It can be understood that the light groove 2221 utilizes the principle of concave lens. The light-transmitting area is used to transmit the light emitted by the light-emitting piece 31 to the outside of the switch, so that the user can see it. The light-transmitting area can be made of light-transmitting material or hollow structure.

[0034] Further, in one embodiment, the light groove 2221 is in the shape of a hemisphere. When the light groove 2221 is in the shape of a hemisphere, its groove wall can gather the light emitted by the light-emitting piece 31 to the center of the light groove 2221. Therefore, the light from the newly gathered light source to each position is more uniform, and the newly gathered light source is closest to the light-transmitting area without increasing the processing difficulty, which achieves the best brightening effect.

[0035] Please see Figures 5-7In one of the embodiments, the shell assembly 20 further comprises a shell 21, the light-transmitting unit 22 comprises a decorative piece 221 and a base 222, and the outer wall of the decorative piece 221 is attached to the inner wall of the shell 21, the inner wall of the decorative piece 221 is provided with the light-transmitting area, and the base 222 is connected to the shell 21, and one end of the base 222 is provided with a light collecting groove 2221, the light emitted by the light emitting piece 31 is conducted to the decorative piece 221 through the base 222, and is refracted to the light-transmitting area by the outer wall of the decorative piece 221 or the inner wall of the shell 21, and finally is emitted outward through the light-transmitting area.

[0036] In this way, the base 222 is responsible for providing the light collecting groove 2221 corresponding to the light emitting piece 31, and conducting the light from the light collecting groove 2221 to the decorative piece 221, and the light propagation path is single; the decorative piece 221 is responsible for conducting the light to the light-transmitting area on the inner wall of the decorative piece 221 after being refracted by the outer wall or the inner wall of the shell 21, so as to collect the light again, avoid light loss, and further improve the brightness and uniformity; the shell 21 can be used to shield the light and constrain the light conducting path; in addition, the light-transmitting unit 22 is assembled together after being processed by the decorative piece 221 and the base 222 respectively, and the processing difficulty is lower.

[0037] It can be understood that the material of the component responsible for light transmission must be a light-transmitting material, that is, the light collecting groove 2221, the area responsible for light transmission of the base 222, the inner wall and the outer wall of the decorative piece 221 all need to adopt a light-transmitting material, and the higher the light transmission rate, the better the effect. Specifically, acrylic material, PC plastic and the like can be adopted.

[0038] Preferably, in one of the embodiments, the base 222 is connected to the shell 21 by screws, and the decorative piece 221 is connected to the shell 21 by adhesion. In other embodiments, the connection mode of the base 222 and the decorative piece 221 to the shell 21 can also adopt other forms.

[0039] In one of the embodiments, the shell assembly 20 is arranged around the circumference of the switch assembly 30; the base 222 has a bottom surface 2222 in the shape of a ring, the light emitting piece 31 is arranged along the circumference of the switch assembly 30, and each light emitting piece 31 is located in the projection of the bottom surface 2222 on the switch assembly 30, and the light collecting groove 2221 is opened in the bottom surface 2222; the bottom surface 2222 and the side wall of the base 222 are communicated to form a light conducting path, and the side wall of the base 222 is connected to the side wall of the decorative piece 221 to conduct the light between the outer wall and the inner wall of the decorative piece 221.

[0040] Thus, the light emitting member 31 arranged in a circumferential ring matches the bottom surface 2222 of the ring, and each light emitting member 31 is matched with a corresponding light collecting groove 2221, and the light is completely confined in the sidewall of the base 222. The light propagation path is conducted along the sidewall of the base 222, the light is more uniform and more beautiful. The light emitting member 31 can be a ring structure or a plurality of point light emitting members arranged in a ring. The light collecting groove 2221 is correspondingly arranged as one or more.

[0041] Of course, it is understood that the ring here refers to a shape arranged in a circle along the circumference of the switch assembly 30, which can be a circular ring or other shapes, for example, a rectangle, and the light collecting groove 2221 on the base 222 is also opened along the rectangular path, and the light emitting member 31 still corresponds to the light collecting groove 2221.

[0042] In one embodiment, the sidewall of the base 222 is an arc-shaped curved surface protruding inward, and the inner diameter of the circle formed by the bottom surface 2222 is smaller than the inner diameter of the end of the base 222 connected to the decorative member 221. The outer wall of the decorative member 221 is an arc-shaped curved surface protruding outward, and the inner diameter of the end of the decorative member 221 connected to the base 222 is smaller than the inner diameter of the other end of the decorative member 221.

[0043] Thus, the light propagation path is emitted from the inside to the outside along the arc-shaped curve, and then folded back to the inside of the light transmission area, which is convenient for light refraction and conduction, avoids light loss, and is more beautiful.

[0044] In one embodiment, the switch assembly 30 includes a box body 32 and a driving plate 34, the base 222 is arranged on one side of the box body 32, and the driving plate 34 is connected in the box body 32. The driving plate 34 is electrically connected with the light emitting member 31, and the box body 32 has a limiting hole 321 corresponding to the position of the light emitting member 31 on the side close to the base 222.

[0045] Thus, the limiting hole 321 facilitates the installation of the light emitting member 31, prevents the light emitting member 31 from falling off the box body 32, and facilitates the light emission of the light emitting member 31. The driving plate 34 can control the light emitting member 31 to be lit or extinguished.

[0046] Specifically, the light emitting member 31 is arranged as an LED lamp bead.

[0047] Preferably, the limiting hole 321 has a plurality of limiting holes, which are uniformly and spacedly arranged along the circumference of the box body 32. The light emitting member 31 and the light collecting groove 2221 are correspondingly arranged with a plurality of limiting holes, so that each light emitting member in the limiting hole 321 can emit light towards the light collecting groove 2221, and the light collecting groove 2221 completes the collection and refraction of the light.

[0048] Specifically, please refer to Figure 4The plurality of limiting holes 321 are arranged in a circle. The angle between the center lines of adjacent limiting holes 321 is 18°, i.e., the 20 limiting holes 321 are arranged at equal intervals. Since the light emitting member 31 is arranged in the limiting hole 321, the circular ring formed by the light emitting member 31 arranged in this way can provide uniform and bright illumination.

[0049] In one of the embodiments, the switch assembly 30 further comprises a rotating shaft 33, the box body 32 is connected to the rotating shaft 33, and the shell assembly 20 is mounted on the rotating shaft 33 and can rotate around the rotating shaft 33.

[0050] Therefore, the light emitting switch in the embodiment is a rotary knob structure. The light path design of the switch assembly 30 in the application is particularly suitable for the rotary knob structure.

[0051] Preferably, the driving plate 34 is connected to the box body 32 by screws, and the side of the box body 32 away from the driving plate 34 is further covered by a back plate, which can also be connected to the box body 32 by screws. Of course, in other embodiments, the above three can also be connected by bolts or direct bonding.

[0052] In one of the embodiments, the light emitting switch 100 further comprises a screen assembly 10, the screen assembly 10 is mounted on the rotating shaft 33, and the shell assembly 20 is arranged around the circumference of the screen assembly 10. The base 222 comprises a connecting portion 2223 and a conducting portion 2224, the conducting portion 2224 is connected to the radially outer side of the connecting portion 2223, the connecting portion 2223 is connected to the screen assembly 10, and the conducting portion 2224 is connected to the decorative member 221. In this way, the screen assembly 10, the shell assembly 20 and the switch assembly 30 are connected.

[0053] Specifically, the screen assembly 10 comprises a touch screen unit 11 and an encoder 12, the touch screen unit 11 and the encoder 12 are electrically connected, the encoder 12 has an inner ring 121 and an outer ring 122 which can rotate relative to each other, the touch screen unit 11 is connected to the inner ring 121, the inner ring 121 is connected to the rotating shaft 33, the connecting portion 2223 is fixedly connected to the outer ring 122 of the encoder 12, and the shell 21 is fixedly connected to the conducting portion 2224. Due to the relative rotation characteristics of the inner ring 121 and the outer ring 122 of the encoder 12, the light emitting switch 100 realizes the rotation of the shell 21 relative to the touch screen unit 11 and the box body 32 through the encoder 12, and triggers the contact switch of the encoder 12 according to the rotation to realize the electrical signal output, so as to realize the adjustment, selection and other functions of the rotary knob.

[0054] Preferably, the connecting portion 2223 and the encoder 12 are fixedly connected by buckling, and the rotating shaft 33 is also fixedly connected to the encoder 12 by buckling structure, which is convenient for disassembly and maintenance in later period.

[0055] In one of the embodiments, the light-transmitting region is located between the screen assembly 10 and the shell 21 along the radial direction of the shell assembly 20, so that the light emitted by the light-emitting member 31 is emitted around the screen assembly 10, which is more beautiful and easier to be recognized by the user.

[0056] Preferably, the screen assembly 10 is away from the plane in which the side of the switch assembly 30 is located, which is the first plane; and the projection of the decoration member 221 on the first plane is at least partially located radially outside the projection of the switch assembly 30 on the first plane. In this way, the area of the decoration member 221 exposed outward is ensured, so as to ensure the illumination area.

[0057] Preferably, the conducting part 2224 is curved and forms an arc structure towards the radially outer side along the direction from the box body 32 to the screen assembly 10.

[0058] In this way, since the box body 32 is set to be small for the convenience of assembly with the shell 21, and the decoration member 221 is at least partially located radially outside the box body 32 and the touch screen unit 11 for better display effect, the base 222 not only supports the screen assembly 10, but also guides the light located radially inside to the top of the decoration member 221. Since the conducting part 2224 is arc-shaped, the arc structure has stronger carrying capacity, which not only has the effect of guiding light, but also makes the structural strength of the elements inside the shell assembly 20 higher and more stable.

[0059] Further, the decoration member 221 is provided with a light-shielding part 2211 away from the side of the switch assembly 30, the light-shielding part 2211 is set to be opaque and can shield the propagation of light, and the light-shielding part 2211 constitutes a pattern structure.

[0060] In this way, during the outward propagation of the light in the decoration member 221, part of the light is shielded by the light-shielding part 2211 and cannot be emitted out of the light-transmitting member, and the light at the position where the light-shielding part 2211 is not provided can normally be irradiated and emitted out, so that the area where the light-shielding part 2211 is provided presents the color of the light-shielding part 2211, and the area where the light-shielding part 2211 is not provided, i.e., the light-transmitting region, presents the color of the light, thus forming a rich visual effect.

[0061] In order to facilitate the propagation of light from the base 222 to the top of the decoration member 221, the inner wall of the shell 21 is set to be arc-shaped, and the outer wall of the decoration member 221 is adapted to the arc-shaped structure of the inner wall of the shell 21, so that when the light propagates upward along the vertical direction in the decoration member 221, the light will be refracted by the inner wall of the shell 21 and finally emitted towards the direction of the light-shielding part 2211.

[0062] Compared with the prior art, the utility model discloses a light groove 2221 is set up on the side of the light transmission unit 22 towards the light emitting part 31, the light emitting part 31 emits light to the light groove 2221 and converges to the ball center position of the light groove 2221 after refraction, that is, the ball center position of the light groove 2221 becomes a new light source point, and the light source is more uniform after moving up, and the light effect is better.

[0063] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0064] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
