Description

Additionally-arranged brake pedal arrangement of motor vehicle

Technical Field

The invention relates to an additional brake pedal of a steering wheel type motor vehicle and position arrangement thereof, which are suitable for a steering wheel type electric vehicle or other vehicles with similar driving methods, such as an automatic transmission vehicle and the like.

Background

In recent years, new energy vehicles, particularly steering wheel type electric vehicles, have been popular. The automobile has no clutch, and the arrangement of a brake pedal and an accelerator pedal (also called as an accelerator) is the same as that of an automatic-gear car, namely, the accelerator is arranged at the right and the brake, and the left clutch is arranged at the left. This arrangement enables the electric vehicle to be driven in the same manner as the automobile, and the person who will drive the automobile can drive the electric vehicle. The small low-speed four-wheel electric vehicle is also a good news for many old, weak, women and children needing transportation, more and more people are driving the vehicle, and more people want to drive the vehicle by themselves.

However, according to the standard driving action, the accelerator and the brake pedal of the vehicle are operated by the right foot, so that accidents are easily caused by mistakenly stepping on the accelerator while stepping on the brake. This is also an important reason and thought concern that prevents the four-wheel electric vehicle from becoming an old, weak, women and children scooter. In order to prevent such accidents, there are some technical solutions in addition to strengthening the driving training. Such as: a speed limiter is arranged on the scooter for the old; for another example: the Chinese invention patent CN 201811091539.7 has the advantages of improving the driving safety of the automobile by adjusting the positions of the accelerator and the brake of the automobile. But it is not compatible with existing car driving methods.

Disclosure of Invention

The invention aims to provide a motor vehicle such as a steering wheel type electric vehicle or an automatic transmission vehicle which can conveniently carry out brake operation by a left foot, so as to prevent or greatly reduce accidents of mistakenly stepping on an accelerator while stepping on a brake, greatly facilitate the old, the weak, women and children who do not drive the traditional vehicle technology to learn and drive the electric vehicle and the old to ride instead of walk more safely, and enable people who have the prior driving technical experience to still conveniently and freely drive according to the prior technical habits of the people and not to destroy the prior driving habits. The invention can also be used on other motor vehicles with brake pedal on the middle and accelerator pedal on the right and left without pedal.

The technical scheme of the invention is as follows:

on the basis of the arrangement of the brake pedal of the existing motor vehicle without the clutch pedal, such as a steering wheel type electric vehicle or an automatic gear car, on the middle, the accelerator pedal on the right and the clutch-free pedal on the left (see the right side of fig. 1, 4 is the brake and 6 is the accelerator), the position of the clutch-free pedal left is additionally provided with the brake pedal 8, so that a left foot can conveniently step on the motor vehicle, and the motor vehicle can perform brake operation (which can be called as a left foot brake pedal) as the original brake pedal 4 in the middle. See fig. 2, right, where 6 is the accelerator pedal.

Thus, the driver can conveniently perform the braking operation by using the left foot. This makes many the old, weak women and children that need the electronic car of steering wheel formula to ride instead of walk more convenient safer, because brake and acceleration advance (throttle) are operated by different feet respectively, is difficult to produce and wants to step on the brake but the maloperation of stepping on accelerator pedal by mistake. For people who have experience in driving automobiles, the driver can still conveniently drive the automobile by using a method which is used by the driver for a long time, namely a method for driving the automatic transmission automobile and a method for operating an accelerator and a brake pedal by using a right foot. The pedal arrangement is shown to the right in fig. 2.

Detailed Description

The first implementation mode comprises the following steps: on the basis that the brake pedal of the existing steering wheel type electric vehicle or automatic gear car is arranged on the right side and the left side of the middle accelerator pedal without a clutch pedal, a left foot brake pedal is additionally arranged on the left side in a vacant position, so that the left foot can conveniently step on the left brake pedal, and a master brake pump (also called a brake controller) can be controlled to perform braking action when the brake pedal is stepped on. One of the specific schemes is described below by taking the most commonly used oil brake mechanism of the four-wheel electric vehicle as an example, and the following description refers to the accompanying drawings:

fig. 1 is a general four-wheel electric vehicle or automatic transmission motor vehicle pedal arrangement and structure principle, the left side is a side view, the right side is an arrangement of a brake pedal and an accelerator pedal seen from a driver seat, 4 and 6 are the brake pedal and the accelerator pedal (accelerator) respectively, and the left side is left: 1 is a master cylinder, 2 is a piston column of the master cylinder, 3 is a brake pedal lever, 5 is a fixed shaft (a lever fulcrum), and 7 is an oil outlet pipe of the master cylinder. When the brake pedal 4 is pressed down, the piston column 2 is pressed down by the lever 3 to press brake oil in the master cylinder 1, and the brake oil flows to the brake cylinders of the wheels from the oil outlet pipe 7 in the arrow direction to perform braking.

The bold black portion of FIG. 2 is one way of adding a left foot brake pedal to the left of the present invention: 5 is a lengthened fixed shaft (lever fulcrum), 12 is a metal pipe sleeved on the shaft 5, 8 is a left foot brake pedal, 9 is a left foot brake lever, the upper end of the left foot brake lever is fixed on the metal pipe, 11 is a brake master cylinder pressure lever, the upper end of the brake master cylinder pressure lever is also fixed on the metal pipe, and 10 is a widened structure of the head part of a brake master cylinder piston column, so as to ensure that the lever 3 and the brake master cylinder pressure lever 11 can press down the piston column 2, 1-7 and have the same structure as that shown in figure 1. Thus, when the left brake pedal 8 is stepped on, the left brake lever 9 will drive the metal tube 12 and the master cylinder pressure lever 11 to rotate around the shaft 5, the master cylinder pressure lever 11 will press the piston post head widening structure 10 and the piston post 2 to squeeze the brake oil in the master cylinder 1, and the brake oil will flow out from the oil outlet pipe 7 and flow to the brake sub-pumps of each wheel in the arrow direction for braking.

If the pedal 4 is depressed, the piston rod 2 is depressed as described in paragraph 0012, above, to complete the braking action. It is easy to see that the piston column 2 of the master cylinder can be effectively pressed down to complete the braking action regardless of the pedal 4 or the pedal 8.

For vehicles using other brake mechanisms such as an air brake, an oil-gas hybrid brake and the like, a brake pedal capable of controlling a brake master cylinder or a brake controller can be arranged on the left side according to the principle.

In the above scheme, it can be known from the lever principle that as long as the lever 3 is the same as the power arm and the resistance arm of the lever combined by 9 and 11, and 12, the force generated by the left brake pedal 8 and acting on the piston column 2 of the brake master cylinder is the same as or very close to the force generated by the original brake pedal 4 on the piston column 2, so that the moving distance of the piston column 2 is the same as or very close to the moving distance, and the generated braking effect is the same as or very close to the moving distance. Experiments also prove that the left brake pedal can completely and effectively brake.

The second embodiment: the brake pedal of the existing steering wheel type electric vehicle or automatic gear car is widened to the left side on the basis of the arrangement that the middle accelerator pedal and the accelerator pedal are not provided with clutch pedals on the right side and the left side, the width reaches the position of a common automobile clutch, and the left foot can be conveniently stepped on. As shown in fig. 3, 13 is a brake pedal widened to allow easy depression of the left foot, and 14 is an accelerator pedal.

Although embodiments have been described, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the appended claims.
