The invention discloses a CAN bus instrument with a heat dissipation function. The instrument comprises a CAN bus instrument main body, wherein a CAN bus interface is formed in a back surface of the instrument panel main body, the instrument panel main body is divided into a front main body and a rear main body, a first groove is formed in an inner wall of the front side of the rear main body, anLED light bar is embedded in the first groove, a light guide plate is inserted in the first groove, a light shield is integrally formed on the front main body, first heat dissipation holes are formedin an outer surface of the light shield, obliquely-downward heat dissipation fins are integrally formed on the back of the rear main body, and second heat dissipation holes are formed in the positions, between every two adjacent heat dissipation fins, of the back of the rear main body. The instrument is advantaged in that the inverted-V-shaped heat dissipation fins can improve the heat dissipationeffect, a light guide plate can realize shading under the condition of strong external light, so observation of an internal speedometer and a tachometer is facilitated, when intensity of the externallight is intense, LED lamp beads can be turned on to irradiate the instrument, so brightness of the instrument can be increased, and the reading of an instrument panel can be seen clearly under the condition of intense illumination intensity.
本发明公开一种具有散热功能的CAN总线仪表,包括CAN总线仪表主体,仪表盘主体的背面上开设有CAN总线接口,仪表盘主体分为前置主体和后置主体,后置主体前侧的内壁上开设有第一凹槽,镶嵌有LED灯条,第一凹槽内插有导光板,所述前置主体上一体成型有遮光罩,遮光罩外表面开设有第一散热孔,后置主体背部一体成型有斜向下的散热片,相邻两个散热片的后置主体背部开设有第二散热孔。倒V型的散热片能够增加散热效果,且导光板能够实现在外部光线强烈的情况下实现遮光,方便内部车速表和转速表的观看,在外界光线强度剧烈的时候,可以打开LED灯珠,照射到仪表上,能够增加仪表的亮度,从而在光照强度剧烈的情况下看清仪表盘的示数。
