Referring to fig. 1 to 5, a knob assembly 100 according to an embodiment of the present invention includes a key assembly 10, an outer ring assembly 16, and a knob support assembly 20.

The key assembly 10 includes a knob cover 12 and a light emitting assembly 14, and the knob cover 12 is located on a light emitting side of the light emitting assembly 14. The outer ring assembly 16 includes a knob outer ring 18, the knob outer ring 18 being optically transparent, and the light assembly 14 being located in a space defined by the knob outer ring 18. The knob bracket assembly 20 mounts the key assembly 10 and the outer ring assembly 16. The knob assembly 100 is configured such that light emitted by the light emitting assembly 14 exits circumferentially at the knob outer ring 18.

When the light emitting assembly 14 emits light, the light ring can be formed in the circumferential direction of the knob outer ring 18, so that the user can have richer interaction experience, and the knob assembly 100 can be lighted on the side surface.

Specifically, the key assembly 10 and the outer ring assembly 16 are mounted on the knob bracket assembly 20, the knob cover 12 is located on the light-emitting side of the light-emitting assembly 14, the knob outer ring 18 is transparent, the light-emitting assembly 14 is located in the space defined by the knob outer ring 18, the knob cover 12 can be made of opaque material, the knob outer ring 18 is made of transparent material, and the transparent material includes semi-transparent material and full-transparent material. When the light emitting assembly 14 emits light, the light is emitted from the circumferential direction of the knob outer ring 18, and an aperture is formed in the circumferential direction of the knob outer ring 18, so that a user has richer interaction experience, and the knob assembly 100 is lightened on the side surface.

In some embodiments, referring to fig. 3 and 10, the outer ring assembly 16 further includes a knob decoration ring 22, the knob decoration ring 22 is located in front of the knob outer ring 18, the knob cover 12 and the knob decoration ring 22 have an overlapping region 23 in a projection direction of the front surface of the knob assembly 100, and the knob decoration ring 22 and the knob cover 12 are opaque. Thus, the front side shading of the knob assembly 100 can be ensured, and the side lighting effect can be realized.

Specifically, the key assembly 10 and the outer ring assembly 16 are mounted on the knob bracket assembly 20, the knob cover 12 is mounted in front of the light emitting assembly 14, when the light emitting assembly 14 is powered on, the light emitting assembly 14 emits light, since the knob outer ring 18 is a transparent plastic member, the light can be refracted directly, and the knob cover 12 and the knob decorative ring 22 are made of opaque materials, the light of the knob assembly 100 cannot be seen right in front. In order to prevent the front surface of the knob assembly 100 from being transparent, in terms of structural design, the knob cover 12 has an overlapping region 23 in the projection direction of the knob decorative ring 22 on the front surface, so that the front shading effect is ensured, light cannot penetrate out from the front surface, only the periphery of the appearance of the knob assembly 100 can emit light, and the knob assembly 100 is viewed from the front surface and has an aperture effect.

The projection direction of the front surface of the knob assembly 100 may be a direction viewed from the front to the back of the knob assembly 100.

In some embodiments, the knob cover 12 is optically transparent. In this way, the effect that the front surface of the knob assembly 100 is also transparent can be achieved.

Specifically, the knob cover 12 is located in front of the light emitting assembly 14, and when the knob cover 12 is made of a light-transmitting material, the effect that the whole front and side surfaces of the knob assembly 100 are light-transmitting can be achieved. The light transmission effect of the knob cover 12 comprises a semi-transparent effect and a full-transparent effect, and meanwhile, the knob cover 12 can be subjected to silk-screen printing processing, so that the knob cover 12 has a partial light transmission effect.

However, when a metal piece or a plated piece is used, the creepage distance between the knob bezel 22 and the light emitting element 14 needs to be considered, and when the creepage distance is not sufficient, the point discharge which is easy to generate static electricity burns out the circuit system of the whole machine. When the knob button position is provided with an opening, the minimum creepage distance is the straight line distance from the knob decorative ring 22 to the light-emitting component 14. In order to improve the electrostatic protection capability of the knob assembly 100, at least one of the knob cover 12 and the knob intermediate column 24 is provided with a protection rib, so that the electrostatic protection problem of the knob assembly 100 can be solved, and the safety of an electrical appliance is protected.

In some embodiments, referring to fig. 11 and 13, the protective ribs include a first protective rib 26 and a second protective rib 28, the first protective rib 26 is disposed on the lower surface of the knob cover 12, the second protective rib 28 is disposed on the upper surface of the knob intermediate pillar 24, and the first protective rib 26 and the second protective rib 28 are disposed opposite to each other and jointly separate the light emitting assembly 14 and the knob bezel 22.

When the knob bezel 22 is made of a non-conductive material, such as plastic or vacuum-plated plastic, the creepage distance requirements are as follows:

the creepage distance = a + b + c + d + e + f + g is more than or equal to 10mm;

wherein, as shown in fig. 14, the creepage distance between the knob decoration ring 22 and the first protection rib 26 is a, the creepage distance between the knob decoration ring 22 and the second protection rib 28 is b, the creepage distance between the first protection rib 26 and the second protection rib 28 is c, the creepage distance between the first protection rib 26 and the knob column 24 is d, the creepage distance between the second protection rib 28 and the knob column 24 is e, the creepage distance between the knob decoration ring 22 and the knob cover 12 is f, and the creepage distance between the knob decoration ring 22 and the first protection rib 26 is g.
