This utility model discloses a manual / automatic triggering device, including a device body, a manual operating mechanism, and an automatic trigger. The manual operating mechanism includes a movable contact component and an operating end. The device body includes a limiting window and a slider. The slider is placed in the limiting window. The movable contact component and the operating end are connected by the slider. When the operating end slides, it causes the movable contact component to contact the automatic trigger, and the automatic trigger is activated. When the operating end slides, it causes the movable contact component to separate from the automatic trigger, and the automatic trigger is deactivated. The limiting window limits the slider, allowing the movable contact component to continuously trigger the automatic trigger.

This utility model discloses a wiring mechanism for an axial flux motor, including a box side plate. A top cover plate is fixedly connected to the top of the box side plate, and an upper end cover is fixedly connected to one side of the outer surface of the top cover plate. Multiple waterproof metal glands are fixedly installed on one side of the outer surface of the upper end cover. An upper terminal block and a lower terminal block are fixedly installed inside the box side plate. In this utility model, through the upper terminal block, shaped copper busbar, lower terminal block, and waterproof metal glands, the high-voltage wiring harness is connected to the motor through the waterproof metal glands. When installing the high-voltage wiring harness, it is not necessary to open the junction box cover plate, avoiding the risk of water leakage due to improper installation of the junction box cover plate and the risk of accidentally dropping the flange nut into the motor when opening the junction box cover plate to install it. This method of installing the high-voltage wiring harness also improves assembly efficiency and avoids poor contact and intermittent connections caused by improper assembly.
