  • Publication number: 20250137304
    Abstract: A lock device structure includes an assembly of a case body and an actuator body, a linking member and a slide body mounted on the case body. The actuator body has two arm sections and a notch section positioned between the two arm sections. An operation member and an elastic member are disposed in the notch section. The elastic member serves to make the operation member reciprocally move in an axial direction of the actuator body. The linking member has a first end pivotally connected with the actuator body (or the operation member) and a second end connected with the slide body. When an operator pulls (and pushes) the operation member to move, the actuator body is permitted to move from a closed position to an open position to drive the linking member and the slide body to move.

  • Publication number: 20240237311
    Abstract: A heat dissipation is used to dissipate heat for a power module of an AC-to-DC conversion module. The heat dissipation system includes a chiller, a heat exchanger, a first circulation pipeline, a second circulation pipeline, a first throttle valve, and a control module. The chiller, the heat exchanger, and the first circulation pipeline form a first circulation loop to circulate a low-temperature coolant. The second circulation pipeline is disposed on one side of the power module to form a second circulation loop, and absorbs a heat source generated by the power module by circulating a high-temperature coolant. The control module opens the first throttle valve to introduce the low-temperature coolant into the second circulation loop based on a temperature of the high-temperature coolant being greater than a temperature threshold so as to control the temperature to be less than or equal to the temperature threshold.
