Abstract: An unmanned vehicle chassis includes: a chassis bracket, a front wheel assembly, a middle wheel assembly, and a rear wheel assembly that engage the chassis bracket, a driving unit disposed on the chassis bracket and configured to drive the unmanned vehicle chassis to move, a rocker arm connected to the chassis bracket, where the rocker arm rotates around an axis of the middle wheel assembly, and the middle wheel assembly and the rear wheel assembly are mounted at both ends of the rocker arm, respectively, and connected to the chassis bracket through the rocker arm, and a driving mechanism disposed on the chassis bracket and configured to control the rocker arm to move.

Abstract: An unmanned vehicle chassis includes: a chassis bracket (1); a front wheel assembly (2), a middle wheel assembly (3), and a rear wheel assembly (4) that engage the chassis bracket (1); a driving unit (5) disposed on the chassis bracket (1) and configured to drive the unmanned vehicle chassis to move; a rocker arm (6) connected to the chassis bracket (1), where the rocker arm (6) rotates around an axis of the middle wheel assembly (3), and the middle wheel assembly (3) and the rear wheel assembly (4) are mounted at both ends of the rocker arm (6), respectively, and connected to the chassis bracket (1) through the rocker arm (6); and a driving mechanism (7) disposed on the chassis bracket (1) and configured to control the rocker arm (6) to move.

Abstract: The present disclosure provides an information processing method and an electronic device. The electronic device comprises a first body, a second body and a rotatable connection member. The first body is connected with the second body by the rotatable connection member. The rotatable connection member has a first using state corresponding to a first rotation damping, and a second using state corresponding to a second rotation damping. In the case the rotatable connection member is in the first using state, the first body can be rotated with respect to the second body at the first rotation damping. The rotatable connection member is changed from the first using state to the second using state to keep a fixed angle between the first body and the second body in the case that a first instruction is received. The second rotation damping is greater than the first rotation damping.
