The invention provides portable GPS navigation equipment capable of automatically maintaining temperature difference change. The equipment comprises a protection frame, a sun-shading cavity is formedin the upper side in the protection frame, a sun-shading mechanism used for shading the sun and preventing temperature rise is arranged in the sun-shading cavity, and the sun-shading mechanism comprises a sun-shading block connected in the sun-shading cavity in a sliding mode; one end of the sun-shading block is fixed with a sun-shading block spring with the other end in fixed connection with thesun-shading cavity. The equipment is simple in structure and easy to implement, sunlight irradiating the surface of a navigator can be automatically shielded according to the sun-shading structure, heat dissipation can be achieved on the navigator automatically according to the cooling mechanism, the rotating angle of the protection frame can be adjusted through an adjusting mechanism, so that overheating caused by local air temperature rise due to long-time irradiation in the same direction is avoided, and damage caused by influence on the service life of a navigation battery and the touch sensitivity of a liquid crystal screen is avoided; and the portable navigator is prevented from falling off due to trolley collision.
本发明的一种温差变化自动维护的便携式GPS导航设备,包括保护架,所述保护架内上侧设有遮阳腔,所述遮阳腔内设有用于遮挡太阳防升温的遮阳机构,所述遮阳机构包括在所述遮阳腔内滑动连接的遮阳块,所述遮阳块一端固定有另一端与所述遮阳腔固定连接的遮阳块弹簧,该设备结构简单,容易实施,根据遮阳结构能够自动对照射在导航仪表面的太阳光进行遮挡,根据降温机构能够自动对导航仪进散热,根据调整机构能够调整保护架的旋转角度,从而避免由于长时间同一方向照射造成局部气温升高而过热,进而避免影响导航的电池寿命且影响液晶屏幕的触摸灵敏度而损坏,根据固定机构对放置在保护架内的导航仪进行稳定,防止小车碰撞使便携导航仪跌落。
