With the rising price of crude oil and the requirement of domestic environmental protection, new energy automobiles become a key industry for the country. For many years, electric vehicles have become accepted by the public and have been popularized by the government. At present, electric vehicles on the market are various, but the operation modes of the electric vehicles are basically the same as the operation modes of electric sightseeing vehicles in terms of accelerator operation, brake operation, gear shifting operation and the like of drivers, and the operation modes mainly depend on the internal structures of the electric vehicles. All electric vehicles are equipped with brake and accelerator pedals. After the accelerator pedal is stepped on, the accelerator control electric controller controls the output current to drive the motor, so that the electric automobile enters a running state from a static state. The swing angle of the acceleration arm determines the current intensity, and then the speed of the electric vehicle is controlled. When the electric automobile needs to be decelerated on the road, the deceleration can be realized by slightly releasing the accelerator pedal. When braking is needed, the brake pedal is stepped down, the brake master cylinder works, and the rotating speed of the wheels is reduced through the brake system until the vehicle stops.

At present, no structural connection exists between gear shifting, braking and an accelerator of an electric automobile. Therefore, when the vehicle runs forwards or backwards, a driver can shift gears at will, the running electric vehicle backs suddenly, the reverse current of the motor is increased rapidly, and the contact of the reverse gear contactor is easy to ablate or even burn out, so that an accident is caused. Moreover, when the vehicle is moving forward, reverse gear is suddenly engaged, so that passengers are easily injured and mechanical parts are easily damaged.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a brake and shift control device for an electric vehicle includes a pedal arm 1, a first spring 2 connected to a fixed groove at the tail end of the pedal arm 1, a pedal rod 3 fixedly connected to the upper end of the pedal arm 1, a pedal shaft 4 rotatably connected to the middle end of the pedal rod 3, a steel wire rope 5 rotatably connected to the top end of the pedal rod 3, a wrapping 6 wrapped around the steel wire rope 5, a locking block 7 rotatably connected to the other end of the steel wire rope 5, a locking shaft 8 rotatably connected to the top end of the locking block 7, a handle 9 movably connected to the upper end of the locking block 7, a second spring 10 fixedly connected to the bottom end of the handle 9, a handle shaft 11 rotatably connected to the middle end of the handle 9, a top rod 12 fixedly connected to the side end of the handle 9, a shift controller 13 movably connected to the outer side of the handle 9, a third spring 14 movably connected to the inside of the, a second contact 16 is fixedly sleeved inside the third spring 14, the outer side of the handle 9 is movably connected with a forward controller 17, and the outer side of the handle 9 is movably connected with a reverse gear controller 18.

Wherein: the stem 11 is composed of an outer shaft and an inner shaft, the inner ring of the outer shaft is fixedly connected with a clamping block and a spring, and the inner shaft is provided with a thread matched with the inner shaft. This design can make handle 9 possess certain vibrations sense around the rotatory in-process of stem 11, avoids too smooth pivot to make the user lose and uses feeling, reduces and uses experience.

Wherein: the pedal shaft 4, the wrapper 6, the lock shaft 8, the handle shaft 11, the gear shifting controller 13, the forward controller 17 and the reverse controller 18 are respectively and fixedly arranged at the determined positions of the control mechanism board of the automobile.

Wherein: the outer end of the locking block 7 and the bottom end of the handle 9 are respectively provided with a matched buckle structure.

Wherein: the first contact 15 and the second contact 16 are electrically connected with each other, and the first contact 15 and the push rod (12) are electrically connected with each other.

Wherein: the forward controller 17 and the reverse controller 18 respectively have a spring three 14 and a contact one 15 structure, and the handle 9 is fixedly connected with the corresponding mandril 12.

Wherein: the outer rings of the pedal arm 1 structure and the handle 9 structure are respectively provided with a shell for wrapping and fixing the pedal arm and the handle, and the outer ends of the pedal arm 1 and the handle 9 respectively extend out of the shell.

The working principle is as follows: the handle 9 is pushed to rotate around the handle shaft 11 anticlockwise as shown in figure 1, the ejector rod 12 matched with the advancing controller 17 pushes the contact I15 and the contact II 16 to be contacted with each other, the spring III 14 is compressed, and at the moment, the advancing controller 17 is switched on and then the driving motor is in a working state. When the gear shifting position is needed to operate, on the premise that the handle assembly 9 is already engaged in a forward gear, the handle assembly 9 is continuously pushed in the counterclockwise direction, as shown in fig. 2, the push rod 12 matched with the gear shifting controller 13 pushes the first contact 15 and the second contact 16 to be contacted with each other, a trigger signal is given to the gear shifting controller 13, and the vehicle is shifted to a high gear to operate. Further pushing on the handle 9 gives the shift control 13 a further trigger signal and the vehicle is shifted to low gear, which is the cycle. When the handle 9 is released, the handle 9 will automatically reset due to the action of the second spring 10. Wherein, the first contact 15 of the forward controller 17 is spaced from the bottom surface to buffer the structural conflict when the handle 9 continues to rotate. Furthermore, the reverse process steps controlled by the reverse controller 18 by rotating the handle 9 clockwise are the same. The device for realizing the change of the high-speed and low-speed gears by continuously pushing the handle 9 on the premise that the handle 9 is already engaged with the forward gear is the high-low gear circulating gear shifting mechanism.

When the bottom of locking piece 7 and handle 9 pins each other, can fix handle 9, avoid handle 9 mistake under the normal condition to touch and lead to the vehicle to start, only when locking piece 7 clockwise turning, just can normal rotation when breaking away from with handle 9 bottom, in addition, handle 9 is rotatory back when breaking away from the state with locking piece 7, locking piece 7 resets, can play the effect of keeping out to handle 9, avoid when contacting with the controller, after user of service loosens handle 9, because reset under the effect of two 10 springs, lead to starting operation failure, and only when breaking away from with locking piece 7, handle 9 just can normally reset.

Comparing fig. 5 and fig. 6, when the pedal is stepped on, the pedal arm 1 drives the pedal rod 3 to rotate around the pedal shaft 4, meanwhile, the first spring 2 is compressed, the steel wire rope 5 is stretched outwards from the foreskin 6 while the pedal rod 3 rotates, the steel wire rope 5 at the handle 9 is contracted into the foreskin 6, the locking block 7 is driven to rotate clockwise around the locking shaft 8, so that the effect of disconnecting the handle 9 is achieved, the pedal is released, the first spring 2 extends, other structures are driven to reset, and due to the fixation of the foreskin 6 and the toughness of the steel wire rope 5, the locking block 7 is pushed to reset and is mutually clamped with the handle 9, and the state of locking the handle 9 is locked again.

Therefore, by adopting the mutual control method of the braking and gear shifting device, the vehicle is required to firstly step on the brake pedal from neutral gear to forward gear, from neutral gear to reverse gear, or from forward gear to neutral gear, and from reverse gear to neutral gear, so that the safe operation of the vehicle is ensured. However, when the forward gear is engaged, the brake pedal does not need to be depressed when the downshift from the high gear or the upshift from the low gear is performed.
