However, as the new energy tricycle market continues to expand, its safety and stability issues have become increasingly prominent, among which the performance of the brake device is particularly critical.
[0003] Traditional tricycle brakes usually use a mechanical brake system, which uses human or mechanical force to apply brakes on the wheels to achieve deceleration or stopping. However, this braking method has disadvantages such as long braking distance and unstable braking effect. Especially under high-speed driving or heavy load conditions, the braking performance deteriorates more significantly, which is difficult to meet the high requirements of new energy tricycles for braking performance.
[0004] With the advancement of technology, advanced technologies such as electronic braking system (EBS) and anti-lock braking system (ABS) have been gradually applied to the automotive field, significantly improving braking performance and safety. However, the application of these technologies in new energy tricycles still faces many challenges, such as high system cost and poor adaptability.
[0005] Therefore, it is necessary to design a brake device for a new energy tricycle to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] Reference Figure 1 to Figure 2 As shown, the utility model provides a brake device for a new energy tricycle, including a brake caliper body 1 and a brake disc 9. The brake caliper body 1 is fixedly mounted on the vehicle body, and the brake disc 9 is fixedly mounted on the wheel hub. The brake disc 9 is arranged in the middle of the opening of the brake caliper body 1, and a gap is arranged between the brake disc 9 and the brake caliper body 1. Grooves 2 are arranged on both sides of the opening of the brake caliper body 1. A coil seat 4 is fixedly connected to the side of the groove 2 away from the brake disc 9. An excitation coil 3 is wound on the coil seat 4. Reset components are arranged on both sides of the coil seat 4. A pressure plate 5 is arranged on the side of the coil seat 4 close to the brake disc 9. The pressure plate 5 is slidably connected to the brake caliper body 1 through the reset component. A permanent magnet 8 is fixedly embedded on the side of the pressure plate 5 close to the coil seat 4. The permanent magnet 8 is arranged corresponding to the coil seat 4. A brake pad 7 is fixedly connected to the side of the pressure plate 5 close to the brake disc 9.
[0024] In this embodiment, the two coil seats 4 are symmetrically arranged on both sides of the brake disc 9, and the excitation coils 3 wound on the two coil seats 4 are electrically connected to the brake control system of the three-wheeled vehicle. The brake control system can control the synchronous power on and off of the two excitation coils 3 and the current size, thereby realizing the control of the size of the force between the brake pad 7 and the brake disc 9. The pressure plate 5 is a non-magnetic body and will not be affected by the magnetic field generated by the power supply of the excitation coil 3.
[0025] By controlling the excitation coils 3 on both sides of the brake disc 9 to be energized at the same time, the excitation coils 3 generate a magnetic field to repel the permanent magnet 8 and the coil seat 4. The permanent magnet 8 overcomes the force of the reset component and drives the pressure plate 5 away from the coil seat 4. The pressure plates 5 on both sides of the brake disc 9 simultaneously drive the brake pads 7 to contact the brake disc 9. At this time, it is a braking state. The friction between the brake pads 7 and the brake disc 9 forces the rotating brake disc 9 to slow down and stop, thereby achieving braking. The magnitude of the magnetic force can be controlled by controlling the current on the excitation coil 3, and thus the brake can be applied under different driving speeds.
[0026] By controlling the excitation coils 3 on both sides of the brake disc 9 to be powered off at the same time, the magnetic field on the coil seat 4 disappears, and the pressure plate 5 drives the brake pad 7 to separate from the brake disc 9 under the action of the reset component. At this time, it is in a released state, and the brake disc 9 operates normally driven by the wheel hub.
[0027] The utility model can reduce the cost and improve the braking effect and reliability at the same time.
[0028] Furthermore, the reset assembly includes a sliding pin 14, a baffle 13 is slidingly sleeved on the sliding pin 14, a groove 11 is opened in the horizontal direction on the side of the opening of the brake caliper body 1 close to the pressure plate 5, the baffle 13 is fixedly connected to the inner wall of the groove 11, an elastic member is provided on the sliding pin 14, the elastic member is arranged between the baffle 13 and the pressure plate 5, one end of the elastic member is fixedly connected to the baffle 13, and the other end of the elastic member is fixedly connected to the pressure plate 5, the end of the sliding pin 14 away from the brake disc 9 is fixedly connected to the correction block 12, the correction block 12 is slidably matched with the groove 11, the other end of the sliding pin 14 is fixedly connected to the side of the pressure plate 5 close to the coil seat 4, the baffle 13 is arranged between the correction block 12 and the pressure plate 5, the sliding pin 14, the correction block 12, the baffle 13, and the elastic member are all arranged in the groove 11.
[0029] Furthermore, the elastic member is a tension spring 15 , which is sleeved on the sliding pin 14 , and two ends of the tension spring 15 are fixedly connected to the baffle 13 and the pressure plate 5 , respectively.
[0030] The combined effect of the correction block 12 and the baffle 13 can prevent the sliding pin 14 from swinging in the braking state, thereby improving the stability of the connection between the pressure plate 5 and the brake caliper body 1, thereby improving the reliability of braking. The tension spring 15 can pull the pressure plate 5 to reset, and the pressure plate 5 drives the brake pad 7 and the brake disc 9 to change from the braking state to the released state.
[0031] Furthermore, a heat insulating pad 6 is provided between the pressure plate 5 and the brake pad 7 .
[0032] The heat insulation pad 6 can effectively reduce the heat transfer between the brake pad 7 and the pressure plate 5, protect the permanent magnet 8, and ensure the effectiveness of braking.
[0033] Furthermore, a protective cover 16 is fixedly sleeved on one end of the coil seat 4 close to the pressing plate 5, and the protective cover 16 is in contact with the inner wall of the groove 1 2.
[0034] The protective cover 16 can prevent foreign matter such as mud and water from entering the device when the device is in a braking state, thereby affecting the performance and life of the excitation coil 3.
[0035] Furthermore, the brake disc 9 is provided with a plurality of heat dissipation holes 10 at equal intervals along the circumferential direction.
[0036] The heat dissipation holes 10 can increase the contact area between the brake disc 9 and the air, thereby accelerating the heat dissipation and preventing the brake disc 9 from being deformed or losing braking performance due to overheating.
[0037] The brake device for a new energy tricycle provided by the utility model has the following working principle: when braking is required during driving of the vehicle, the excitation coils 3 on both sides of the brake disc 9 are controlled to be energized at the same time, the excitation coils 3 generate a magnetic field to repel the permanent magnet 8 and the coil seat 4, the permanent magnet 8 overcomes the pulling force of the tension spring 15, and drives the pressure plate 5 away from the coil seat 4, the pressure plates 5 on both sides of the brake disc 9 synchronously drive the brake pads 7 to contact the brake disc 9, friction is generated between the brake pads 7 and the brake disc 9, and the rotating brake disc 9 is forced to slow down, the interaction force between the brake pads 7 and the brake disc 9 is controlled by controlling the current passed through the excitation coil 3, and then the braking urgency of the vehicle is controlled, when normal driving is required, the excitation coils 3 on both sides of the brake disc 9 are controlled to be de-energized at the same time, the magnetic field on the coil seat 4 disappears, and the pressure plate 5 drives the brake pads 7 to separate from the brake disc 9 under the pulling force of the tension spring 15, and is in a released state at this time, the brake disc 9 operates normally under the drive of the wheel hub, and the vehicle resumes driving at a normal speed.
