  • Patent number: 11394197
    Abstract: It discloses a ring-connected bridge-type multi-port hybrid DC circuit breaker. When the number of ports is n, n is an integer greater than or equal to 2, the ring-connected bridge-type multi-port hybrid DC circuit breaker includes: an upper DC bus bar, a lower DC bus bar, n thyristor arms, n diode arms, a main breaker branch, and n bypass branches; each thyristor arm connects in series with a diode arm, forming a series circuit; a bypass branch is connected between every two adjacent series circuits, a port is provided at the connection point of the thyristor arm and the diode arm in each series circuit, and the port is used to connect the protected components or the DC lines.

  • Patent number: 11035538
    Abstract: A lens structure includes a lens body; an outer surface of the lens body is provided as a single curved surface; and an inner surface of the lens body is provided thereon with at least two inner curved surfaces that are continuously connected. In the present solution, through the design of the plurality of inner curved surfaces, the light pattern and the energy distribution can be controlled flexibly, the applicability of the lens design is maximally greatly improved, and meanwhile, a truly feasible solution is provided for the defect where in some scenes it is impossible for the existing conventional structure to distribute light. In addition, multiple functions may be implemented at the same time, such as, low beam, high beam, bending and fog lamp; and multiple functions are combined into one lens module for implementation.
