Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a vehicle pull cord auxiliary mechanism, in particular to a device for connecting a pull cord of a vehicle pull cord auxiliary mechanism to a pedal. Background Art
[0002] In order to ensure the safety of drivers and passengers, an automatic brake system is added to the original vehicle to stop the vehicle in an emergency. In the added pull rope auxiliary mechanism, how to connect the pull rope to the original brake pedal is a problem. The current method is to drill a hole in the existing brake pedal, pass the connecting pull rope through the hole and then fix it with a fixing. This method has a big disadvantage.
[0003] After the connecting rope passes through the hole, the rope and the hole are in contact. When the rope is continuously stressed, the rope will be worn off. Even if the hole is made very smooth, it cannot solve the problem. The rope and the smooth hole also have relative movement, which causes the rope to be worn off.
[0004] After the pull rope pulls the pedal, as the angle of the pedal changes, the angles of the pull rope and the pedal also change accordingly, so that the pull rope and the pull rope sheath have relative movement, resulting in friction between the pull rope and the sheath bracket, and the pull rope and the sheath will be worn off.
[0005] When the pull rope auxiliary mechanism is not working, people operating the brake pedal will continuously bend the pull rope, causing excessive fatigue of the pull rope, so that the pull rope will be worn off.
[0006] Therefore, it is necessary to provide a device for connecting the pull cord of a pull cord auxiliary mechanism for a vehicle to the pedal to solve the above technical problems. Utility Model Content
