  • VEHICLE, ENERGY CONVERSION DEVICE AND CONTROL METHOD THEREOF
    Publication number: 20230038790
    Abstract: The present disclosure relates to the technical field of vehicles, and provides a vehicle and an energy conversion device and a control method therefor. The energy conversion device includes a motor controller, a bus capacitor, a first switch module, a motor, and a second switch module. By controlling the first switch module and the second switch module to be turned on/off, a motor driving circuit can be formed by a battery pack, the first switch module, the bus capacitor, the motor controller, and the motor, and a charging and discharging circuit can be formed by the battery pack, the second switch module, the motor, the motor controller, and the bus capacitor.

  • Pressing head structure for testing key durability
    Patent number: 7895901
    Abstract: A pressing head structure (100) for testing key durability includes a pressing mechanism (10), a rubber head (40), a connecting mechanism (20) and a balance mechanism (30). The pressing mechanism includes a sliding rod (12) and a first spring (16). The first spring is placed over the sliding rod. The connecting mechanism connects the pressing mechanism and the rubber head. The balance mechanism is rotatably fixed to the connecting mechanism. The balance mechanism engages with the pressing mechanism. When the sliding rod moves down, the first spring and the balance mechanism together supply an unaltered resultant resistance in the moving direction of the sliding rod.
