The relay 140 has a first excitation coil 141 and a first excitation. Switch 142. The first exciting coil 141 is opposite to the first exciting switch 142, and the first exciting coil 141 has an input terminal 141a and an output terminal 141b. The first field switch 142 is connected between the positive pole of the power source 110 and the starter 0134-A21856TWF (N2); A-470; hawdong 9 1329155 motor 120. Here, the first exciting switch 142 is in a normally open state, and it can be closed by the exciting operation of the first exciting coil 141. The protection control unit 150 is coupled between the fourth terminal 135b of the brake switch 135 and the input terminal 141a of the first excitation coil 141, which can be used to control the excitation operation of the first excitation coil 141. In more detail, the protection control unit 150 has an electronic control loop 151, a second excitation coil 152 and a second excitation switch 153. Electronic control loop 151 is coupled to fourth terminal 135b of brake switch 135. The second exciting coil 152 is connected to the electronic control circuit 151.

Still as shown in Fig. 2, after the power switch 130 is activated (e.g., after an operator or driver turns the power switch 130 on with a key), the first end point 131 thereof communicates with the second end point 132. Then, when the brake switch 135 is activated (e.g., when the operator or the driver presses the upper lever), the third end point 135a communicates with the fourth end point 135b. At this time, a circuit is formed between the power source 110, the power switch 130, the brake switch 135, and the brake lamp 170, that is, a current flows from the anode of the power source 110 through the power switch 0334-A21856TWF(N2): A-470. : hawdong 1329155 130, brake switch 135 and brake light 170, thus causing the brake light 170 to illuminate. Meanwhile, when the start switch 160 is activated (for example, when the operator or the driver presses the start switch 160), between the power source 110, the power switch 130, the brake switch 135, the protection control unit 150, the relay 140, and the start switch 160, A loop is formed, that is, current flows from the anode of the power source 110 through the power switch 130, the brake switch 135, the protection control unit 150, and the relay 140. Here, the current flowing into the protection control unit 150 is divided into two currents, one current flows through the electronic control circuit 151, and the other current flows through the second excitation switch 153. At this time, the electronic control circuit 151 receives an external signal (for example, an engine speed signal or an igniter signal) to determine whether the engine has been started or is running. When the external signal received by the electronic control circuit 151 indicates that the engine is not being started or is not in operation, the second excitation coil 152 connected to the electronic control circuit 151' is not excited but flows through the second excitation. The current of the switch 153 flows through the first exciting coil 141 of the relay 140 at the same time. At this time, the first excitation switch 142 is closed by the excitation operation of the first excitation coil 141, thereby forming a loop between the power source 110, the relay 140 and the starter motor 120, that is, the current will be from the power source 110. The positive electrode flows through the first excitation switch 142 of the relay 140 and the starter motor 120. Therefore, the starter motor 120 is activated and the engine is started. On the other hand, when the external signal received by the electronic control circuit 151 indicates that the engine has been started or is running, the second exciting coil 152 connected to the electronic control circuit 151 is excited, and the second exciting switch 153 is activated. It is turned off by the exciting operation of the second exciting coil 152. At this time, 0134-A21856TWF(N2); A'470:hawdong 1329155 current cannot flow through the first exciting coil 141 of the relay 140 via the second exciting switch 153, so that the first exciting coil 141 does not cause the exciting operation. As described above, the first field switch 142 of the relay 140 remains in the off state, and current cannot flow through the starter motor 120 via the first field switch 142. Therefore, the starter motor 120 is not activated, thereby preventing damage and protecting the running engine. In summary, the engine starting device disclosed in the present invention can prevent the starting motor from being activated again when the engine has been started or is running, thereby avoiding damage to the starting motor, thereby reducing engine operating load and battery. Power consumption and fuel waste.
