The invention discloses vehicle-mounted navigation equipment which comprises two fixing plates and an equipment body; one breathable mesh plate is fixed to the inner walls of the two sides of the equipment body through bolts; a fan is fixed to the outer wall of one side of the breathable mesh plate through bolts; air holes distributed at equal intervals are formed in the outer wall of one side ofthe equipment body; filter screens are fixed to the inner walls of the air holes through bolts; the fan is located to one side of the air holes; movable grooves are formed in the outer walls of one sides of the two fixing plates; sliding grooves are formed in the inner walls of one sides of the two fixing plates; and sliding plates are slidably connected to the inner walls of the two sliding grooves. By means of the breathable mesh plate, the fan, the air holes and the filter screens, the effects of ventilation and heat dissipation in navigation equipment can be achieved; meanwhile, the filterscreens can prevent dust in outside air from flying into the equipment body, and therefore the service life of the navigation equipment is prolonged, and a certain protection function is achieved.

    本发明公开了一种车载导航设备,包括两个固定板和设备本体,所述设备本体两侧内壁通过螺栓固定有同一个透气网板,所述透气网板一侧外壁通过螺栓固定有风扇,所述设备本体一侧外壁开设有等距分布的透气孔,所述透气孔内壁通过螺栓固定有过滤网,所述风扇位于透气孔一侧,两个所述固定板一侧外壁均开设有活动槽,两个所述固定板一侧内壁均开设有滑槽,两个所述滑槽内壁均滑动连接有滑动板。本发明通过设置有透气网板、风扇、透气孔和过滤网,能够对导航设备内起到通风散热的效果,同时过滤网能够避免外界空气中的粉尘飘入到设备本体内部,从而提高了导航设备的使用寿命,具有一定的保护功能。
