Technical Field

The invention relates to the field of garden tools, in particular to a power switch and automatic walking equipment.

Background

On automatic walking equipment such as intelligent mowing robot, need to set up switch for switch on or turn off the main power. The existing power switch usually adopts a key form, the key is keyed into a mounting seat with a key slot, and the key is rotated to toggle a switch in the mounting seat, so that the power supply is triggered to be switched on or off.

Patent No. US9218924 discloses a switch key structure comprising three rotational positions LIVE, OFF and STORAGE. When the key is in the OFF position, the key can be inserted or removed. When the key is in the STORAGE position, the key may be secured in the keyway without falling out while keeping the power supply off. When the key is positioned at the LIVE position, the automatic walking equipment can be triggered to start the working state.

However, since the switching between the different states is arranged in the same plane and is distinguished only by the angle of rotation of the key, and since the stop position of the key in this patent is located between the LIVE position and the OFF position, the direction of rotation of the key is the same when the key is turned from the OFF position to the LIVE position and the stop position, and can therefore be distinguished only by the feel of the user or by observation of the angle of rotation of the key. It is difficult for the user to clearly distinguish between the LIVE and STORAGE locations. Therefore, it is easy for the user to rotate the key that should be rotated to the store position to the LIVE position, or to rotate the key that should be rotated to the LIVE position to the store position. The power switch is easy to be operated by a user by mistake to trigger the automatic walking equipment to be started under an improper condition, so that potential safety hazards exist.
