An outdoor moving device includes a main body, a first energy storage device, a second energy storage device, and a connection assembly. The first energy storage device is capable of supplying power to the outdoor moving device and includes at least one first energy storage unit. The second energy storage device is capable of supplying power to the outdoor moving device and includes at least one second energy storage unit. The connection assembly is used for mounting the second energy storage device to the main body. The first energy storage device is detachably mounted to the main body, the first energy storage device is detachable from the main body to supply power to another power tool, the first energy storage unit includes a first positive electrode made of a first material, and the second energy storage unit includes a second positive electrode made of a second material.

Outdoor moving device

A riding lawn mower, including: a frame; a seat; a walking assembly and a walking motor; a cutting assembly and a driving motor configured to drive the cutting assembly; a first energy storage device configured to supply power to at least one of the walking motor or the driving motor, the first energy storage device including at least one first energy storage unit, the first energy storage device detachably mounted to the frame and enabled to supply power to a handheld power tool when detached from the riding lawn mower; and a second energy storage device configured to supply power to at least one of the walking motor or the driving motor, the second energy storage device including at least one second energy storage unit; wherein an energy density of the second energy storage unit is different from an energy density of the first energy storage unit.

Outdoor walking equipment

A riding lawn mower, including: a frame; a seat; a walking assembly and a walking motor; a cutting assembly and a driving motor configured to drive the cutting assembly; a first energy storage device configured to supply power to at least one of the walking motor or the driving motor, the first energy storage device detachably mounted to the frame and enabled to supply power to a handheld power tool when detached from the riding lawn mower; and a second energy storage device configured to supply power to at least one of the walking motor or the driving motor; wherein a ratio of a total energy of the second energy storage device to a total energy of the first energy storage device is greater than or equal to 2 and less than or equal to 20.

A self-propelled machine includes a drive motor, a handle having two grips, an electromechanical converting device, and a speed adjusting element configured to move relative to the handle to adjust a rotational speed of the drive motor and configured to be operated by a user when the user holds one of the two grips with a single hand. The speed adjusting element is disposed between the two grips. The electromechanical converting device is configured to convert a positional change of the speed adjusting element into an electrical signal for adjusting the rotational speed of the drive motor. The speed adjusting element is movable between a first position and a second position. The rotational speed of the drive motor when the speed adjusting element is in the first position is greater than the rotational speed of the drive motor when the speed adjusting element is in the second position.

A lawn mower includes a blade configured to cut grass, a chassis, configured to accommodate the blade, and front and rear wheels connected to the chassis. A motor is configured to drive at least the rear wheel to rotate. A detection apparatus detects the rotational speed of the front wheel and a controller controls the motor. Accordingly, the speed of a front wheel is detected to control a moving speed of the lawn mower, thereby enhancing the performance of the lawn mower and improving the user's experience.
