Description

Switch is shaded and is separated light support

Technical Field

The utility model belongs to the technical field of the auto switch, concretely relates to switch is shaded and is separated light support.

Background

As an operating element of a motor vehicle, various indicators are required to illustrate the use of the operating element. The character backlight light source LED is arranged so that the night time operating member is also clearly visible. At present, backlight light isolation of switching different characters in the industry is mainly achieved through the matching of a button and a switch main body (the LED light rays can be irradiated to be partially overlapped). The light-blocking principle is as follows: there is not the clearance between switch shell and the button, and light can't jet out the switch assembly to can avoid the light leak.

The existing light-blocking scheme mainly has the following defects: the button needs to be transparent, a transparent material needs to be selected, and the risk of light leakage exists when the button is used for blocking light; the button needs to be provided with a light blocking structure, and the shape of the button cannot be too complicated; the switch main body structure needs to bear a movement matching structure and an installation structure of the switch main body structure and an environment piece, and meanwhile, a light blocking structure needs to be realized, the structure is complex, the requirements on the strength and the toughness of the switch main body structure are high, and therefore, the selectable materials are limited.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problem that exists among the prior art, the utility model provides a switch is shaded and is separated light support.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a switch backlight light-isolating support comprises a light-tight support body, wherein the support body is arranged between a switch main body and a symbol panel, is in zero-clearance fit with the symbol panel and is overlapped with a part capable of being irradiated by backlight light in the switch main body; and the support body is provided with a light hole matched with the switch main body.

Furthermore, the side wall of the light hole of the bracket body is provided with a positioning hole matched with the buckle on the switch main body.

Further, the bracket body and the switch main body are fastened together by screws.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model provides a switch is shaded and is separated light support mainly comprises the opaque support body of installing between switch main part and symbol panel, through making zero clearance matching of support body and symbol panel, overlaps with the part that the light source in a poor light can shine in the switch main part, can prevent that light in a poor light from spilling (realizing promptly separating the light) from the clearance between switch main part and the symbol panel. The problem of prior art through button and switch main part cooperation realize that the button that separates the light existence needs printing opacity, separates the light effect poor, switch major structure need undertake the motion matching structure and with the mounting structure of environment spare, realize separating the light structure again simultaneously, the structure is complicated, requires higher to its intensity, toughness is solved.

Detailed Description

The present invention will be described in further detail with reference to fig. 1 to 5.

The utility model provides a switch is shaded and is separated light support, including lightproof support body 1, support body 1 is installed between switch main part 4 and symbol panel 7, and with symbol panel 7 zero clearance fit, overlap with the part that the light of being shaded can shine in switch main part 4; and the support body 1 is provided with a light hole 2 matched with the switch main body 4.

In the present embodiment, the stent is mainly composed of a stent body 1. The shape and structure of the bracket body 1 are matched with those of the switch main body 4, that is, the shape and structure of the bracket body 1 are not fixed, and the specific shape and structure depend on the shape and structure of the switch main body 4. Fig. 1 shows a schematic view of an elongated holder body 1, which is adapted to the switch body 4 shown in fig. 2. The holder body 1 is provided with a light-transmitting hole 2 for transmitting light emitted from a backlight light source (e.g., LED) to illuminate a symbol on the symbol panel 7. The shape and number of the light-transmitting holes 2 depend on the specific structure of the switch body 4, and 5 light-transmitting holes 2 are shown in fig. 1 and 3. The holder body 1 is mounted between the switch main body 4 and the symbol panel 7 as shown in fig. 5. The bracket body 1 and the symbol panel 7 are fitted with a zero clearance and are overlapped with a portion of the switch main body 4 where the backlight can be irradiated (the overlapped portion is of course also a zero clearance, and they are overlapped near the upper edge of the switch main body 4 in fig. 5). This design prevents backlight light from leaking out of the gap between the holder body 1 and the symbol panel 7 and the switch main body 4. The support body 1 is made of opaque materials, so that light can be prevented from leaking out of the support body 1, and the light isolation effect is further improved. The bracket body 1 only needs to be firmly fixed on the switch main body 4, the material selection does not have the requirements on the aspects of movement and installation matching of the switch main body 4, and light transmission is not needed, so that the material with lower cost, such as PA6, PA66, PP, ABS and the like, can be selected.

As an alternative embodiment, the sidewall of the light hole 2 of the bracket body 1 is provided with a positioning hole 3 matched with the buckle 5 on the switch main body 4.

This embodiment provides a technical scheme of the location of support body 1 and switch main part 4. A positioning hole 3 is formed in the side wall of each light hole 2, the position and the shape of the positioning hole 3 are matched with the buckle 5 on the switch main body 4, and the buckle 5 penetrates through the positioning hole 3 to achieve positioning between the support body 1 and the switch main body 4.

As an alternative embodiment, the holder body 1 and the switch main body 4 are fastened together by screws.

This embodiment shows a technical solution for fixing the bracket body 1 and the switch main body 4. The two are fixed by screws, and a screw hole 6 is arranged on the switch main body 4. The position and number of the screw holes 6 are not particularly limited and may be selected according to the specific structure of the switch main body 4.

The above description is only for the description of several embodiments of the present invention, but the scope of the present invention should not be considered as the protection scope of the present invention, in which all the equivalent changes or modifications or the equal-scale enlargement or reduction etc. made according to the design spirit of the present invention should be considered as falling into the protection scope of the present invention.
