Self-pull-in automobile back door lock with introduction of PWM (Pulse Width Modulation) control
The invention discloses a self-actuation automobile back door lock introducing PWM control, which comprises a motor, the motor is connected with a lock body, and the lock body has two continuous states: a first state: the door lock is actuated to return to a first return position; in the second state, the door lock is opened to return to the second return position, when the door lock is in the pull-in state, the output voltage of the motor is V1, when the door lock is in the first return position state, the output voltage of the motor is V2, when the door lock is in the open state, the output voltage of the motor is V3, and when the door lock is in the first return position state, the output voltage of the motor is V2; pWM waves with different duty ratios D are introduced according to the output voltage of the motor in different states, so that speed regulation of the motor is realized. The PWM control mode is introduced into the automobile self-actuation back door lock, so that the operation noise of the automobile door lock motor is greatly reduced, and the sound quality of the whole automobile and the user experience are improved.
本发明公开了一种引入PWM控制的自吸合汽车背门锁，包括电机，所述电机和锁体连接，锁体包括两种连续状态：第一状态为：门锁吸合至回到第一回位；第二状态为：门锁开启至回到第二回位，在门锁吸合状态时，电机的输出电压为V1，在所述第一回位状态时，所述电机的输出电压为V2，在门锁开启状态时，电机的输出电压为V3，在所述第一回位状态时，电机的输出电压为V2，根据上述不同状态下电机的输出电压引入不同占空比D的PWM波，从而实现对电机调速。本发明将PWM控制方式引入汽车自吸合背门锁中，大大降低了汽车门锁电机的运转噪音，提高了整车声音品质及用户感受。
