Problems solved by technology
[0005] The invention solves the problem that the existing power-off mode requires the controller to send a circuit breaker signal and cannot transmit the circuit-break signal when the controller fails. A micro switch power-off device for the side door of an electric flatbed car does not need a controller, and adopts a key switch, a tight The double switch function realized by the stop button and the side door micro switch adopts the cooperation between the micro switch, the strap and the pressure plate, thereby avoiding the occurrence of adhesion during use, effectively saving labor time and cost. After the switch fails, the side door switch can be used as an emergency power-off temporarily to improve the safety of the vehicle

Embodiment
[0041]This embodiment proposes a power-off device for a side door micro-switch of an electric flatbed vehicle. Refer to figure 1 , figure 2 and Figure 4 , an electric flatbed side door micro switch power-off device, which is integrally arranged on the inner side of the vehicle side door, including a power-off device and a key switch, the power-off device includes a charging door panel 3,
[0042] Key switch: connect with micro switch 1 in series, when the key switch and micro switch 1 are closed at the same time, the whole vehicle can be powered on;
[0043] Charging door 3: It can be opened and closed automatically, and is in contact with the micro switch 1 when the charging door is closed;
[0044] Micro switch 1: The main function of micro switch 1 is to induct the opening or closing of the charging door 3;
[0045] Toggle 7: Toggle 7 and pressure plate 6 cooperate with each other to lock the charging door 3.
[0046] refer to Figure 1 to Figure 3 , including the ch...

The invention provides an electric flat car side door microswitch power-off device which is installed on the inner side of a car side door and comprises a power-off device body and a key switch, the power-off device body comprises a charging door plate and a lug, the key switch is connected with a microswitch in series, and when the key switch and the microswitch are closed at the same time, the key switch is powered on; the charging door plate is automatically opened and closed, and is tightly pressed with the microswitch when being closed; the microswitch is used for sensing opening and closing of the charging door plate; and the lug is matched with the pressing plate and is used for locking the charging door plate. According to the side door microswitch power-off device of the electric flat car, a controller is not needed, a key switch, an emergency stop button and a side door microswitch are adopted, the double-switch function is achieved, the microswitch, a lug and a pressing plate are matched, and therefore the adhesion condition in the using process is avoided, the labor time cost is effectively saved, and the working efficiency is improved. And when the ganged switch fails, the side door switch can be temporarily and emergently powered off, so that the safety of the whole vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of forklift trucks, in particular to a power-off device for a side door micro-switch of an electric flatbed truck. Background technique [0002] Forklifts are industrial vehicles, which realize the loading and unloading, stacking and short-distance transportation of goods, which greatly improves work efficiency and reduces the high intensity of manual labor. widely. Therefore, people have certain requirements for the safe use of forklifts. The invention mainly includes a micro switch assembly, a side door assembly and a matching wiring harness. It is characterized in that the micro switch is placed on the inner surface of the side plate, and the side door is opened as a trigger. The condition of the micro switch, so that when the side door is opened for charging, the circuit of the whole vehicle is directly cut off to ensure the personal safety of the operator. The existing technical solution is to trigger...
