The present disclosure relates to a front passenger-side operating device for a motor vehicle, in particular to a flexible transmission-based front passenger-side brake control device and a flexible transmission-based front passenger-side operating system for a motor vehicle, and belongs to the technical field of motor vehicles.
With the rapid development of automobile industry and the improvement of people's living standards, automobiles have entered thousands of households. According to a survey conducted by the National Bureau of Statistics of China, China has become a country with large automobile production and consumption, and the number of motor vehicles in China is about 100 million. According to traffic laws and regulations, ordinary people have to pass the required examinations before becoming qualified drivers, and many people choose to study at driving schools in order to master driving skills. Driving practice is a necessary practical part of learning to drive, and driving schools generally have coach cars for students to practice. Due to limited time in contact with cars, students often feel at a loss after getting on the cars, and sometimes accelerator pedals are mistakenly used as brake pedals, leading to accidents. The existing coach cars are equipped with auxiliary braking devices. Once the student operates in fault, the coach sitting in the front passenger-side seat can brake urgently through the auxiliary braking device to prevent accidents. In addition, obtaining a driving license through examinations after driving school training does not mean becoming a skilled vehicle driver. Every year, a large number of “driving license drivers” have become invisible “road killers”, and major fatal road traffic safety accidents caused by unskilled driving skills frequently occur. Therefore, it is proposed that the existing private cars can be equipped with car braking devices for front passengers like coach cars, so that new hands can be accompanied by old hands sitting in the front passenger-side seat when driving. In case of an emergency, the old hands can take decisive braking measures, thus effectively preventing and reducing traffic accidents.
The Chinese utility model patent “Simple Braking Device for Front Passenger” (ZL201420456563.7) discloses a braking device for a front passenger. Referring to
At present, there are also cable-type front passenger-side braking devices using steel wire ropes in the market. Although the defect that the rigid transmission front passenger-side braking devices are difficult to install is overcome, the strength of the steel wire ropes as transmission parts is limited. In some special emergency abnormal situations, the sudden excessive force on a front passenger-side brake pedal often leads to the breakage of the steel wire ropes, so that it is difficult to avoid accidents.

Referring to
When a front passenger presses on the brake pedal 5, the front passenger-side brake pedal assembly is pressed down to rotate around the rotating shaft 13, and then the movable end of the brake cable 16 is pulled by the brake pedal arm 4, so that a relative position between the movable end of the brake cable 16 and the first fixing plate 19 on the base plate 1 is changed.

Referring to
The realization of the braking function is the same as that in the first embodiment. The realization process of an accelerator function is as follows.
When a front passenger presses on the front passenger-side accelerator pedal 23, the front passenger-side accelerator pedal 23 is pressed down to rotate around the rotating shaft 13, and then the movable end of the accelerator cable 26 is pulled, so that a relative position between the movable end of the accelerator cable 26 and the second fixing plate 29 on the base plate 1 is changed. The length of the accelerator cable 26 between the second fixing plate 29 and the front passenger-side accelerator pedal 23 is increased, and the length of the accelerator cable 26 between the second fixing plate 29 and the accelerator cable fixing plate 24 is decreased. The accelerator flexible force transmission sleeve 28 is axially (longitudinally) incompressible, so the relative position between the accelerator flexible force transmission sleeve 28 and the accelerator cable 26 is changed by means of the positioning of the fixed end, which is immovable, of the accelerator flexible force transmission sleeve 28 on the second fixing plate 29 of the base plate 1.

During this process, the accelerator cable 16 between the second fixing plate 29 and the accelerator cable fixing plate 24 becomes tensioned from a loose condition, and the length is relatively decreased, so that like the brake cable 16 and the brake flexible force transmission sleeve 8, the accelerator cable 26 and the accelerator flexible force transmission sleeve 28 has a sufficient margin in length and can initially achieve the loose condition, which is an indispensable condition for realizing the present disclosure as well. The front passenger lifts the foot to remove the pressure on the front passenger-side accelerator pedal 23.
