Description
Technical field
The present invention relates to vehicle switch fields, particularly relate to a kind of automobile-used rotary switch.
Background technique
With the development of automotive electronics, more and more applied to the electronic equipment in automobile, client is to its structure technology
It it is required that also higher and higher, and is then indispensable one as the rotary switch for adjusting the equipment such as air conditioning for automobiles, sound equipment
Point, in order to guarantee user in the case where night or insufficient light can normal use rotary switch, there is a kind of knob
The rotary switch that itself can be shone includes pedestal, the shell of installing on the base, is installed with rotation on the housing
Button, the pedestal are equipped with the PCB with illuminator, knob light transmission setting, so that it is guaranteed that client's energy in the case where insufficient light
It identifies knob position and size, facilitates operation.Although and this rotary switch in order to guarantee knob bright intensity and uniformly
Degree, generally can according to the light emitting angle of illuminator on PCB the multiple illuminators of circumference, but still unavoidable distance shine
The farther away knob portion brightness of body is partially dark, so that formation is different from apart from the closer knob portion light intensity of illuminator, it is bright
Degree is uneven, and knob quality is not high, dims even if devoting a tremendous amount of time in exploitation design, when cannot guarantee that batch production
Consistency；Simultaneously because light source utilization rate is low without concentration structure, in the case of illuminator quantity is excessive, light is sent out everywhere
It dissipates, increases the light leakage risk of rotary switch.
Summary of the invention
The purpose of the present invention: in order to overcome the drawbacks of the prior art, the present invention provides one kind not only to meet the uniformity
It is required that and the high automobile-used rotary switch of light source utilization rate.
Technical solution of the present invention: a kind of automobile-used rotary switch, including shell and knob are provided with band in the shell
The PCB of illuminator, knob light transmission are arranged, and corresponding luminous body position is equipped with guide structure, the light guide in the shell
Structure includes the first light guide ring and the second light guide ring below the first light guide ring, the second light guide ring bottom edge
Its light for being circumferentially with several and capable of being emitted illuminator is diffused into the diffusion part on the second light guide ring, and described second is guide-lighting
The upper surface of circle be additionally provided with can sawtooth by light homogenous diffusion to the first light guide ring bottom surface, first light guide ring is equipped with energy
By the light refraction being communicated up to the refraction part of knob outer peripheral surface, the knob is installed on the first light guide ring.
By adopting the above technical scheme, the diffusion part of second light guide ring makes more light be introduced into second as far as possible
It in light guide ring, conducts inside it, approach is uniformly distributed in the sawtooth uniformly rear export upwards of the second light guide ring upper surface, described
The uniform light light refraction being conducted upwards into the first light guide ring, and will be communicated up by the refraction part of the first light guide ring
Knob outer peripheral surface is exported to, the saturating loss late of light is small, avoids light leakage, realizes bright, uniform illumination effect in knob outer peripheral surface.
The further setting of the present invention: the diffusion part include the setting of corresponding illuminator light source receiving unit and by
The light source receiving unit extends to two extensions of the second light guide ring to two sides, is formed and is engraved between two extensions and the second light guide ring
Emptying aperture.
Using above-mentioned further setting, when the light that light source is emitted is upwardly into extension through the reception of light source receiving unit
Afterwards, the light is formed by two extension inner walls through hollow hole and refracts on corresponding extension outer wall to change big portion
Light splitter direction exports obliquely, after realizing that the diffusion of light, the light diffuse to the second light guide ring, conducts inside it,
To realize the small effect of the saturating loss late of light.
Further setting of the invention: there are three the diffusion part is set, the outer wall of two extensions is in inside in diffusion part
Curved arc is arranged, and the angle in diffusion part between the inner wall of two extensions is in 90 ° of -102 ° of settings, the light source of each diffusion part
Receiving unit is in the same plane.
Further it is arranged using above-mentioned, since light source receiving unit is uniformly arranged in same plane, institute is received bright strong
Degree is consistent, and after light is communicated up, the light is formed by two extension inner walls through hollow hole and refracts to corresponding extension
It is exported obliquely on portion's outer wall to change most of radiation direction, realizes the diffusion of light, the light diffuses to second and leads
It after aperture, conducts inside it, the angle of the inner wall of two extensions is in 90 ° of -102 ° of settings, and light is through two extensions
The effect that inner wall is refracted to corresponding extension outer wall is best, and the outer wall of two extensions is arranged in aduncate arc, diffusion
Effect is best.
Further setting of the invention: if refraction part includes axially to be arranged on the inner wall of the first light guide ring along it
Dry internal tooth, knob outer peripheral surface correspond to internal tooth setting, and internal tooth is equipped with the plane of refraction tilted upward.
