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.

[0028] Example 1

[0029] like Figure 1-Figure 6 As shown;

[0030] A foot parking brake device for vehicle parking comprises a mounting seat 1 mounted at the lower left side of the vehicle, a toothed disc 2 and a bracket plate 15 are welded in parallel on the surface of the mounting seat 1, a pedal arm 9 is arranged between the toothed disc 2 and the bracket plate 15, the pedal arm 9 is rotatably connected with the toothed disc 2 and the bracket plate 15 through a central shaft 14 and a nut A11, the central shaft 14 passes through the toothed disc 2, the pedal arm 9 and the bracket plate 15 in sequence, and a pedal 7 is integrally formed at the end of the pedal arm 9;

[0031] The surface of the pedal arm 9 is installed with a sliding shaft 3 through a locking nut 13. The surface of the sliding shaft 3 is slidably connected to the side of the toothed disc 2. The surface of the toothed disc 2 is provided with a through groove with arc-shaped teeth. The surface of the pedal arm 9 and the inside of the through groove are rotatably connected with a ratchet 4 through a torsion spring 6. The ratchet 4 and the arc-shaped teeth are meshed with each other. Both ends of the torsion spring 6 are fixedly connected to the pedal arm 9, and one end thereof passes through the ratchet 4 and is fixedly connected to the pedal arm 9. The surface of the pedal arm 9 is installed with a ratchet shaft 5 through a nut B12. The ratchet shaft 5 is located in the surface groove of the ratchet 4 and is slidably connected to the ratchet 4.

[0032] A tension spring 8 is connected between one side of the top end of the pedal arm 9 and the mounting seat 1 , a parking cable 10 is provided at the bottom end of the mounting seat 1 , and the top end of the parking cable 10 is connected to the top end of the pedal arm 9 .

[0033] In this embodiment: the mounting base 1 is installed to the left foot placement position at the lower left side of the vehicle. When the foot is parked, the driver's left foot presses down the pedal 7, so that the pedal arm 9 moves forward between the toothed disc 2 and the bracket plate 15, and the parking cable 10 is pulled to make axial movement. At the same time, the pedal arm 9 is limited by the sliding shaft 3 to ensure smooth movement. During the forward movement of the pedal arm 9, the teeth on the ratchet 4 are separated from the teeth on the toothed disc 2, and rotate under the cooperation of the torsion spring 6, the ratchet shaft 5 and the nut B12, thereby driving the rear wheel brake to realize the parking function. When the left foot leaves the pedal 7, the ratchet 4 is in a locked state, achieving good controllability and improving the parking safety performance of the vehicle. At this time, the tension spring 8 is in a stretched state;

[0034] The left foot presses the pedal 7 again, the ratchet 4 automatically separates, the left foot is released, the pedal 7 returns to its original position, the ratchet 4 rotates to its original position, the parking cable 10 is released, and the rear wheel brake is released to the parking state;

[0035] Combined with the above-mentioned repeated movements, the vehicle's parking brake can be used to stop and release the parking brake, that is, the left foot is used to repeatedly step up and down to stop the vehicle and drive the vehicle. The parking brake has a strong force, the vehicle is parked on a slope without slipping, and the safety is good and the operation is safe.

[0036] It should be noted that: this solution is applicable to passenger vehicles in the field of motor vehicles and electric vehicles, and the end of the parking cable 10 is connected to the rear wheel brake.

[0037] It should be noted that, in this embodiment: protective covers can be installed on both sides of the toothed disc 2 to protect the internal structure and to isolate and prevent accidental injuries.

[0038] In an optional embodiment, the ratchet 4 is in a rounded triangular plate-shaped structure, and has a notch on the side away from the mounting seat 1 , and the notch is matched with the protrusion in the through groove of the toothed disc 2 .

[0039] In this embodiment: the above design ensures that the ratchet wheel 4 can perfectly engage with the toothed disc 2, and the teeth can mesh with each other, and thread slippage is not likely to occur.

[0040] In an optional embodiment, when the pedal arm 9 is in the original state, the protrusion is engaged with the notch;

[0041] When the pedal arm 9 is in a vertical state, the teeth of the ratchet wheel 4 mesh with the arc-shaped teeth at the bottom end of the toothed disc 2 .

[0042] In this embodiment: the above are respectively the foot parking brake released brake state and the foot parking brake state, which is easy to operate and ensures that the vehicle is stable and safe when parked on a slope without slipping.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
