The utility model discloses drive
assembly and
mobile carrier. Drive
assembly includes installation support, driver, wheel and elastic part. Installation support is equipped with two vertical board, and driver is located between and is connected with rotation, and the central axis is parallel with the rotation axis and does not coincide. Wheel is directly connected driver, and elastic part connects installation support and driver. When wheel is increased under pressure, driver positive overturn makes wheel go up, and elastic part stores energy, and when pressure is reduced, elastic part releases energy, and driver reverse overturn makes wheel go down. The transmission mechanism is saved, and the structure is simplified, and cost is reduced, and
energy consumption is reduced. Cooperation elastic part realizes bearing, and anti-rolling pressure retraction and reset.
Mobile carrier includes the casing and at least three above-mentioned drive assemblies, and the lower part of casing is equipped with the
accommodation cavity. Drive
assembly is not arranged along the straight line, and is supported stably. When rolling, wheel retracts to the chamber, and the bottom surface of casing is attached to the ground and bears pressure, avoiding the damage of core components, and after rolling, elastic part resets, and wheel jacks up the casing, ensuring normal driving.
