Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a vehicle brake pedal mechanism, including a pedal body 1, a fixed block 2 is fixedly connected to the surface of the pedal body 1, a first connecting rod 4 is fixedly connected to one side of the fixed block 2, a second connecting rod 6 is fixedly connected to the outer wall of the first connecting rod 4, one end of the second connecting rod 6 is rotatably connected to a fixed plate 8, one side of the fixed plate 8 is fixedly connected to an operating rod 9, a handle 7 is fixedly connected to the top of the operating rod 9, a first rotating shaft 10 is fixedly connected to the bottom of the operating rod 9, a base 11 is rotatably connected to the outer wall of the first rotating shaft 10, a sliding assembly is arranged at one end of the first connecting rod 4, and a disassembly mechanism is arranged on the surface of the pedal body 1.

[0025] Specifically, the driver controls the handle 7, which rotates downward, and the second connecting rod 6 is pushed forward to drive the first connecting rod 4 to move. The sliding assembly limits the movement trajectory of the first connecting rod 4. When the first connecting rod 4 moves, the fixed block 2 is pressed down, and the pedal body 1 is further pressed down. When the driver's legs are injured or fatigued, the operation of stepping on the brake is replaced by hand operation, thereby improving the convenience of driving.

[0026] Reference Figure 3 The disassembly mechanism includes a first baffle 14, a first mounting groove 15 is provided on the top of the pedal body 1, the bottom of the first baffle 14 is connected to the inside of the first mounting groove 15, a second mounting groove 17 is provided on the surface of the pedal body 1, and a second baffle 18 is inserted and connected to the inner wall of the second mounting groove 17. The second baffle 18 is located on the side of the pedal body 1 away from the throttle, and the first baffle 14 is located on the side close to the mounting plate 3.

[0027] Specifically, through the setting of the first mounting groove 15 and the second mounting groove 17, a novice driver can insert the first baffle 14 and the second baffle 18 as needed when driving. The setting of the second baffle 18 and the first baffle 14 effectively prevents the driver from being unable to accurately find the brake position or accidentally touching other components due to excessive tension when switching from the accelerator to the brake, thereby improving driving safety.

[0029] Specifically, when the first connecting rod 4 moves, the slider 19 slides in the sliding groove, and the tension spring 20 exerts a pulling force on the slider 19, so that the slider 19 always fits tightly against the inner wall of the sliding groove, thereby ensuring the stability of the movement of the first connecting rod 4.

[0030] Reference Figure 3 A mounting plate 3 is provided at one end of the pedal body 1, and a second rotating shaft 13 is rotatably connected to the surface of the mounting plate 3. One end of the pedal body 1 is fixedly connected to the outer wall of the second rotating shaft 13, and a mounting hole 12 is opened on the surface of the mounting plate 3.

[0031] Specifically, the movement of the pedal body 1 during braking is achieved through the rotation of the second rotating shaft 13, and a mounting hole 12 is provided on the surface of the mounting plate 3 to facilitate the connection between the mounting plate 3 and the automobile chassis or other components, thereby improving the stability of the entire brake pedal mechanism.

[0032] An anti-slip strip 16 is fixedly connected to the surface of the pedal body 1 .

[0033] Specifically, the anti-slip strip 16 is provided to increase the friction between the pedal body 1 and the driver's foot, thereby preventing safety accidents caused by the driver slipping during braking.

[0034] Working principle: When the driver's leg is injured or fatigued, the device is used. First, the fixed block 2 is installed on the pedal body 1, and then the control handle 7 is turned downward. The second connecting rod 6 is pushed forward to drive the first connecting rod 4 to move. The sliding component limits the movement trajectory of the first connecting rod 4. When the first connecting rod 4 moves, the fixed block 2 is pressed down, and the pedal body 1 is further pressed down to complete the braking operation. Through the setting of the first mounting groove 15 and the second mounting groove 17, a novice driver can insert the first baffle 14 and the second baffle 18 as needed when driving, which effectively prevents the driver from being unable to accurately find the braking position or accidentally touching other components due to excessive tension when switching from the accelerator to the brake, thereby improving driving safety. The surface of the pedal body 1 is fixedly connected with an anti-slip strip 16, which increases the friction between the pedal body 1 and the driver's foot, and prevents safety accidents caused by the driver slipping during braking.
