When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1, an embodiment of the present invention provides a driving executing device for an emergency stop of an automobile, including: a motor 110 and a transmission member. The motor 110 may be connected to associated control circuitry on the vehicle. The transmission member is connected to the motor 110, the motor 110 is used for driving the transmission member to operate, and the transmission member is used for driving the brake pedal 200 to act.
Specifically, the control circuit sends an emergency stop signal to the motor 110, the emergency stop signal may be a set of pulse signals, the motor 110 has a demodulator, after the demodulator of the motor 110 receives the set of pulse signals, the demodulator executes a command of turning on the power of the motor 110, the motor 110 starts to rotate after turning on the power, and after the motor 110 rotates, the driving member is driven to move, so as to drive the brake pedal 200 of the automobile to act, thereby implementing emergency braking.
In this embodiment, as shown in fig. 1 to 5, the transmission member includes a first driving block 120, a second driving block 160, a transmission frame 130, and a transmission rod 140. The first driving block 120 is connected to the output shaft 111 of the motor 110. The transmission frame 130 is sleeved on the output shaft 111 of the motor 110 and does not rotate along with the output shaft 111. The second driving block 160 is connected to the driving frame 130.
The second driving block 160 has an initial position, and when the second driving block 160 is at the initial position, a gap exists between the second driving block 160 and the first driving block 120 along the circumferential direction.
