The invention provides an angle-adjustable automobile instrument panel which comprises a panel body arranged on an automobile body. A lower shell is arranged at the bottom end of the panel body. A rotary shaft penetrates out of the middle of the lower shell. The two ends of the rotary shaft are arranged on the automobile body. The lower shell is fixed to the rotary shaft. The rotary shaft is rotated, so that the lower shell rotates around the rotary shaft. An instrument board is installed on the lower shell. A shifting component is arranged below the panel body. A driving component is arrangedat the bottom end of the shifting component and provided with a driving gear. A transmission belt is arranged between the driving component and the lower shell and provided with a transmission gear.A driven gear is arranged below the right side of the lower shell. The optimal angle of the panel body can be adjusted according to different requirements when different people drive an automobile, and the negative effect caused by light reflection of the surface of the panel body is reduced.
