The application discloses a wireless infrared light routing communication system and method for battery pack management. The communication system is composed of a master control unit and slave control units coupled with each battery cell, and four communication modules are configured according to a networking mode. Each communication module contains an infrared transmitting end and a receiving end, and is coupled with surrounding slave control units on a wireless channel to realize full-duplex wireless light communication and form a grid-shaped light communication network among the battery cells. Light signals from the master control unit can be transmitted to target battery cells through multi-hop forwarding of adjacent battery cells as routing nodes. The slave control units of each battery cell do not need to maintain a routing table independently, but judge whether to accept a data frame or forward it through a communication module according to routing information carried in the data frame, so as to realize broadcast communication for all battery cells in the network or light routing communication for specific battery cells. The application has high path selection efficiency and flexible network coverage, and is suitable for wireless light network management of high-density battery packs.

This utility model discloses a main clutch switch structure for harvesting machinery, including two contact groups. Each contact group includes a movable contact and a fixed contact. The fixed contacts are all fixed on the same insulating component. One set of fixed contacts is connected in series in the engine starting circuit to conduct when the clutch is disengaged, allowing starting. The other set of fixed contacts is connected to the input terminal of the vehicle display screen to output an alarm signal when the clutch is engaged. The two sets of movable contacts are mounted on the same movable plate, with the movable contacts and fixed contacts arranged opposite to each other. The movable plate moves through a movable mechanism.

The electronic device of the present invention comprises: a display module; and a digital converter disposed below the display module, and including a folding portion folded about a folding axis extending in a first direction, and a first non-folding portion and a second non-folding portion spaced apart from each other with the folding portion therebetween in a second direction crossing the first direction. The digital converter includes a plurality of sensing coils, different sensing coils among the plurality of sensing coils are shared by a common line, and the common line is disposed at least in the folded portion.
