Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a kinetic energy conversion braking system and a braking device for a new energy vehicle. Background Art

[0002] The braking system is the general term for all braking and deceleration systems installed in a car. Its function is to slow down or stop a moving car, or to keep a stopped car stationary. Since the structure and performance of the braking system are directly related to the safety of the vehicle and personnel, it is considered an important safety part of the car and is widely valued.

[0003] As disclosed in publication number CN209534721U, a kinetic energy conversion brake device for new energy vehicles has the following beneficial effects: the battery pack module is designed as a movable structure, and the kinetic energy of the battery pack is converted into mechanical energy storage by using a spring energy storage method, thereby shortening the braking distance of the vehicle and reducing the kinetic energy consumption of the wheels. It can quickly transfer 1 / 3 of the kinetic energy of the entire vehicle into temporary mechanical energy storage, solving the problem of high-intensity braking energy consumption during emergency braking, allowing the vehicle to achieve emergency braking more quickly and efficiently, effectively solving the problem of brake thermal decay in existing braking solutions, reducing brake shoe friction consumption, reducing brake dust pollution, and efficiently converting the vehicle's kinetic energy into mechanical energy. Kinetic energy can be converted into mechanical energy, shortening the braking distance and improving the safety, reliability and comfort of the vehicle. However, the braking device has a relatively simple structure and cannot provide sufficiently strong braking force, which will lead to a longer braking distance, especially in high-speed driving or emergency braking. The braking effect is not ideal, and it is prone to wear and failure under long-term use and high-intensity braking conditions, which requires more frequent maintenance or faster parts replacement cycles. Compared with traditional friction braking systems, kinetic energy conversion braking devices with simple structures have limited effects in providing braking force. Since they mainly rely on power feedback or regenerative braking, their braking force is not as strong as that of friction braking systems, especially in high-speed driving or emergency braking.

[0004] Therefore, there is an urgent need for a new energy vehicle kinetic energy conversion braking system and a braking device to solve the above problems. Summary of the invention

[0042] The braking device of the new energy vehicle kinetic energy conversion braking system comprises the following steps when in use:

[0043] Step 1: First, the electric power feedback of the motor is used to achieve the braking effect. When the driver releases the accelerator or steps on the brake pedal 4, the brake pedal 4 swings and drives the fixed plate 3 to swing. The fixed plate 3 swings and drives the connecting rod 2 to rotate. The connecting rod 2 rotates and drives the connecting plate 5 to rotate. The connecting plate 5 rotates and drives the guide plate 6 to swing. The guide plate 6 swings and drives the moving plate 7 to move. The moving plate 7 moves and drives the brake shoe 8 to move, so that the brake shoe 8 is tightly fitted with the groove 9. Through the mechanical connection between the motor 31 and the wheel, the movement of the wheel drives the motor to rotate, converting mechanical energy into electrical energy, and then the electrical energy is adjusted and consumed by the electronic control system. The electrical energy is fed back to the motor 31 or the battery 33, thereby achieving the braking effect, reducing the braking distance, and enhancing driving safety.

[0044] Step 2: When the user needs to manually achieve the braking effect, the user presses the handle 20, and the handle 20 swings and drives the fixed rod 17 to swing, and the fixed rod 17 swings and drives the positioning rod 16 to swing, and the positioning rod 16 swings and drives the mounting arm 30 to swing, and the mounting arm 30 swings and drives the positioning block 29 to move, and the positioning block 29 moves and drives the connecting arm 25 to move, and the mounting arm 30 swings and drives the guide arm 27 to move, and the guide arm 27 moves and drives the moving arm 26 to swing, and the moving arm 26 and the connecting arm 25 swing and drive the brake plate 24 to move, so that the brake plate 24 is closely fitted with the disc 23 to achieve the braking effect, which can reduce the loss of kinetic energy.

[0045] When the kinetic energy conversion braking system of the new energy vehicle is in operation, when the driver steps on the brake pedal 4, the braking system converts the kinetic energy of the vehicle into electrical energy and stores the electrical energy in the battery 33. In this way, the energy generated during braking can be recovered and can be reused when needed. The electric heating system 32 can prevent the condensation of the brake and ensure the normal operation of the brake. At the same time, it can also control the heat dissipation of the braking system and improve the performance and life of the brake. The current passes through the coil of the motor 31 to generate a magnetic field, which interacts with the permanent magnet or other magnetic fields to make the motor 31 generate torque, thereby driving the vehicle to move. At the same time, the motor 31 can also convert the kinetic energy generated during movement into electrical energy by reverse operation, thereby realizing energy recovery and extending the cruising range.
