AI Technical Summary
The existing braking system for electric tricycles cannot balance the high sensitivity of disc brakes with the structural simplicity of drum brakes, resulting in poor braking performance and inconvenient maintenance.
It adopts a combined front disc brake and rear drum brake braking structure. Through a dual-path design, it realizes the independent operation and coordinated force of the front disc brake and the rear drum brake. Combined with the brake distribution shaft and brake return spring, it dynamically adjusts the braking force distribution to ensure the sensitivity and stability of the braking system.
It improves braking efficiency, avoids vehicle skidding or fishtailing caused by uneven distribution of braking force, extends the service life of the braking system, and reduces maintenance costs.

Abstract
Claims
1. A front disc brake and rear drum brake combined braking structure for an electric tricycle, comprising a frame, an outer wall at the top of the frame being fixedly connected with a master brake cylinder (6), characterized in that: The output end of the master cylinder (6) is fixedly connected to a brake hose (7), and the end of the brake hose (7) away from the master cylinder (6) is fixedly connected to a front brake slave cylinder (2). The brake master cylinder (6) is provided with a brake pedal (3) on its exterior. The outer wall of the brake pedal (3) is rotatably connected to a disc brake front lever (11). The outer wall of the brake pedal (3) is rotatably connected to a front brake lever (4). The end of the front brake lever (4) away from the brake pedal (3) is fixedly connected to a rear brake lever (5). The end of the rear brake lever (5) away from the front brake lever (4) is fixedly connected to a rear brake (8).
2. The front disc brake and rear drum brake combined braking structure for an electrically driven three wheeled vehicle as claimed in claim 1 wherein: The front brake cylinder (2) is rotatably connected to the outer wall of the front brake disc (1).
3. The front disc brake and rear drum brake combined braking structure for an electrically driven three wheeled vehicle as claimed in claim 2 wherein: The front lever (11) of the disc brake is rotatably connected to a brake rocker arm (9) at the end away from the brake pedal (3). One end of the brake rocker arm (9) is fixedly connected to the outer wall of the frame through a brake return spring. The other end of the brake rocker arm (9) is slidably connected to the inner wall of the master cylinder (6) through the rear lever (12) of the disc brake, and the outer wall of the rear lever (12) of the disc brake is slidably connected to the inner wall of the master cylinder (6).
4. The front disc brake and rear drum brake combined braking structure for an electrically driven three wheeled vehicle as claimed in claim 3 wherein: The outer wall of the rear brake lever (5) is rotatably connected to the brake distribution shaft (10), and the outer wall of the brake rocker arm (9) is rotatably connected to the outer wall of the vehicle frame.
