Description

Technical Field

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

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. The automobile braking system refers to a special braking mechanism installed on the car in order to technically ensure the safe driving of the car and increase the average speed of the car. Generally speaking, the automobile braking system includes two independent devices: the driving brake device and the parking brake device. The driving brake device is operated by the driver's foot, so it is also called the foot brake device.

[0003] The parking brake is operated by the driver's hand, so it is also called the hand brake; the function of the service brake is to slow down a moving car or stop it in the shortest distance; and the function of the parking brake is to keep a car that has been parked on various roads stationary; however, sometimes in an emergency, the two brakes can be used at the same time to increase the braking effect of the car; some special-purpose cars and cars that often travel in mountainous areas, long-term and frequent braking will cause the service brake to overheat, so various types of auxiliary brakes are often added to these cars to stabilize the speed when going downhill.

[0004] At present, in the process of developing new energy vehicles, safety has always been the top priority, and automobile braking is a key link. The existing automobile braking structure is complex, the cost is too high, the braking process is relatively rigid, and there is a certain inertia, which leads to safety hazards. In addition, when braking on slippery roads, the tires will slip, and the safety problem cannot be properly handled. At the same time, a large amount of heat is generated during the braking process, which is easy to cause damage to the internal components and reduce the service life. To this end, we propose a braking device for new energy vehicles. Summary of the invention

[0005] The purpose of the present invention is to provide a braking device for a new energy vehicle to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a braking device for a new energy vehicle, comprising a wheel axle installed in a bracket, a transmission shaft is arranged at the end of the wheel axle, the transmission shaft is connected to a power assembly, a connecting block is arranged on the outside of the transmission shaft, a first friction plate is arranged on the outside of the connecting block, a brake chamber is arranged in the bracket, a piston block is clamped in a movable groove of the brake chamber, an oil pipe is arranged on the upper side of the piston block, and the oil pipe is connected to an oil pump, an adjusting block is arranged at the bottom of the piston block, a second friction plate is arranged at the bottom of the adjusting block, and a cooling mechanism is arranged in the bracket.

[0007] Preferably, the power assembly includes a connecting rod, a shaft sleeve is provided at the bottom of the connecting rod, and the shaft sleeve is fixed on the transmission shaft.

[0008] Preferably, the first friction plate is designed to be arc-shaped, and a ventilation hole is provided on the first friction plate.

[0009] Preferably, the connecting block is movably snap-connected in the limiting seat.

[0010] Preferably, the first friction plate is distributed in a divergent manner on the outer side of the wheel axle.

[0011] Preferably, the cooling mechanism comprises a cooling chamber, a fan is installed in the cooling chamber, and a dustproof net is provided at the air inlet of the cooling chamber.

[0012] Compared with the prior art, the invention has the following beneficial effects: the braking device of the new energy vehicle has a simple and reasonable structural design. By setting the connecting block, the first friction plate, the adjusting block, the second friction plate and other structures to cooperate with each other, the new energy vehicle can lightly step on the brake during the braking process, and the first friction plate on the connecting block and the second friction plate on the adjusting block are in contact to brake, which can achieve the purpose of stable deceleration. At this time, friction braking is generated between the friction plates, which causes less wear on the friction plates. When the brake is further stepped on, the friction plates produce elastic deformation to achieve the purpose of braking. The heat generated by the vehicle during the braking process is dissipated through the ventilation holes, thereby achieving the purpose of auxiliary heat dissipation, thereby achieving the effect of friction braking through the friction force of the friction plate itself, and ensuring the stability and reliability of the braking effect of the device. By setting a cooling component composed of a fan, the friction plate during friction can be continuously cooled and cooled by introducing a cooling airflow during the braking process, so that both can be cooled quickly and the service life of the mechanism is improved. By setting a dustproof net as a filtering mechanism, moisture and impurities in the airflow can be filtered, thereby preventing water vapor and impurities from affecting the braking mechanism.

The oil in the pipeline enters the oil pipe 21 under the action of the oil pump 22, and the piston block 2 is pushed to move inside the piston cavity during the oil spraying process. During the process of pushing out the piston block 2, the second friction plate 24 on the surface of the lower adjustment block 23 contacts the first friction plate 16 on the rotating connecting block 15, so that the braking process of the new energy vehicle is realized through the friction plate with greater friction force.

[0020] Preferably, the power assembly includes a connecting rod 14, and a shaft sleeve 13 is provided at the bottom of the connecting rod 14, and the shaft sleeve 13 is fixed on the transmission shaft 12. By arranging the connecting block 15, the first friction plate 16, the adjusting block 23, the second friction plate 24 and other structures to cooperate with each other, during the braking process of the new energy vehicle, the first friction plate 16 on the connecting block 15 and the second friction plate 24 on the adjusting block 23 are in contact, and braking is performed, which can achieve the purpose of smooth deceleration, and at this time, friction braking is generated between the friction plates, which causes less wear on the friction plates, and the friction plates are further stepped on to produce elastic deformation, thereby achieving the purpose of braking.

[0021] Preferably, the first friction plate 16 is designed to be arc-shaped, and a ventilation hole 17 is provided on the first friction plate 16. The heat generated by the vehicle during braking is dissipated through the ventilation hole 17, achieving the purpose of auxiliary heat dissipation, thereby achieving the effect of friction braking through the friction force of the friction plate itself, ensuring the stability and reliability of the braking effect of the device.
