Description

Technical Field

[0001] This invention belongs to the technical field of detection methods, and specifically relates to a safety detection method for an electric outboard motor. Background Technology

[0002] Outboard motors undergo various tests before leaving the factory. Occasionally, an outboard motor may be accidentally started before water immersion testing. In this case, the propeller spins idly, which poses a significant threat to the safety of testing personnel if there are no protective measures. During the initial startup phase of the outboard motor, abnormal situations such as weed entanglement or obstruction by foreign objects may occur. Without protective measures, it is highly likely to damage parts such as the motor and propeller. Therefore, it is necessary to make improvements. Summary of the Invention

[0003] Based on the above reasons, this invention proposes a safety testing method for an electric outboard motor. The electric outboard motor includes a self-test power point, a first torque value T1 and a second torque value T2 at the self-test power point, wherein the first torque value T1 is less than the second torque value T2. The safety testing method includes the following steps: S1. Start the electric outboard motor; S2. Start self-test mode; S3. Lock the throttle device, and the motor controller controls the power of the drive motor to the self-test power point, recording the output torque value as T. n ; S4. If the output torque value is less than or equal to the first torque value of the drive motor, and the medium in which the propeller is located is air, the output power of the drive motor is kept at the self-test power point, and the outboard motor idle alarm is activated. If the output torque value is greater than or equal to the second torque value of the drive motor, the medium in which the propeller is located is abnormal. At this time, the drive motor stops rotating and the propeller abnormality alarm is activated. If the output torque value is greater than the first torque value and less than the second torque value, the self-test mode is turned off and the limitation of the throttle device is released.

[0004] This invention can prevent the outboard motor from spinning idling and causing injury by detecting the torque value feedback of the drive motor, and can detect the propeller operating conditions to promptly identify abnormal conditions and protect the outboard motor.

[0006] To better illustrate the purpose and advantages of the present invention, the invention will be further described below with reference to the accompanying drawings and examples, but the present invention is not limited to these examples.

[0007] like Figure 1 As shown, a safety testing method for an electric outboard motor, the electric outboard motor including a self-test power point, a first torque value T1 and a second torque value T2 at the self-test power point, wherein the first torque value T1 is less than the second torque value T2, includes the following steps: S1. Start the electric outboard motor; S2. Start self-test mode; S3. Lock the throttle device, control the power of the drive motor to the self-test power point, and record the output torque value T at this time. n ; S4. If the output torque value is less than or equal to the first torque value of the drive motor, the medium in which the propeller is located is air. At this time, the output power of the drive motor is kept at the self-test power point, and the outboard motor idling alarm is activated. If the output torque value is greater than or equal to the second torque value of the drive motor, the medium in which the propeller is located is abnormal. At this time, the drive motor will stop rotating and the propeller abnormality alarm will be activated. If the output torque value is greater than the first torque value and less than the second torque value, the self-test mode is turned off and the throttle device restriction is lifted.
