Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present utility model.

[0026] It should be noted that like reference numerals represent like elements in the following figures. Therefore, once an element is defined in one figure, it may not be further defined or explained in subsequent figures. Embodiment

[0027] This embodiment mainly elaborates on the title of the active and passive braking control system, specifically as follows:

[0028] The active and passive braking control system, referring to the attached Figures 1-5 , includes an electric scooter. The electric scooter has a front wheel assembly 50 and a rear wheel assembly 20. The front wheel assembly 50 and the rear wheel assembly 20 respectively include a front brake assembly 40 and a rear brake assembly 30. The electric scooter also has a steering assembly 60 with a handle 601. A brake trigger assembly 70 is provided on the handle 601. The brake trigger assembly 70 includes a mounting seat 702 provided on one side of the handle 601 and a brake caliper 706 provided on the mounting seat 702. The brake seat has a mounting cavity 700. The brake caliper 706 includes a hinge arm 7061 on one side and a pressing arm 7062 provided on the hinge arm 7061. The hinge arm 7061 is disposed in the mounting cavity 700 and a hinge point 707 is provided between its two ends for hinging with the side wall of the mounting cavity 700 of the brake seat. The length of the upper part of the hinge arm 7061 above the hinge point 707 is greater than the length of the lower part below the hinge point 707. A rear brake cable 703 is connected to the end of the upper part of the hinge arm 7061. The rear brake cable 703 is connected to the rear brake assembly 30. A front brake cable 704 is connected to the end of the lower part of the hinge arm 7061. A steering pulley 708 is provided in the mounting cavity 700 and the rear brake cable 703 is connected to the front brake assembly 40 after being steered. The pressing arm 7062 extends out of the mounting cavity 700. A shifter and a bell are provided on the handle 601 on the other side. This solution realizes that one brake caliper 706 controls two brake assemblies, and at the same time, the clamping force of the front brake is made less than that of the rear brake by the different swinging amplitudes of the hinge arm 7061, thereby avoiding the danger of pitching caused by the front brake suddenly stopping.

[0029] Preferably, the brake seat includes a clamp 701 and a box-shaped body provided on the clamp 701. The brake seat is detachably fixed to the handle 601 by the clamp 701. The mounting cavity 700 is located in the box-shaped body. The clamp 701 is used to fix the box-shaped body, and the box-shaped body is used to mount the brake caliper 706 and the brake cable.

[0030] Preferably, the pressing arm 7062 is connected to the upper part of the hinge arm 7061 at the hinge point 707. The pressing arm 7062 is disposed on the upper part to leave enough space for pressing with the handle 601.

[0031] Preferably, the installation cavity 700 is further provided with a first fixing seat 705 and a second fixing seat 710. The two brake lines pass through the two fixing seats 705 and 710 respectively, and the two brake lines 703 and 704 are provided with limiting rings 7031 and 7041. After the brake is released, the limiting rings 7031 and 7041 abut against the fixing seats 705 and 710. When abutting, the portion of the front brake line 704 between the limiting ring 7041 and the articulated arm 7061 is in a loose state. Since the brake line will retract after being released, the limiting rings 7031 and 7041 are provided to limit the brake line. In addition, the front brake line

[0032] 704 is provided with an idle stroke to ensure that the front brake assembly 40 does not participate in braking at the initial stage of pressing the brake gate 706, and only starts to work when the front brake line 704 is pressed to a taut state.

[0033] Preferably, the electric scooter has a pedal assembly 10, in which a controller, a power supply and a motor are arranged, both of which are connected to the controller, and a steering assembly 60 includes a steering upright, on which a distance sensor is arranged, which is connected to the controller. The distance sensor is used to detect obstacles in front of the vehicle, and when the obstacle is too close, the controller controls the motor to stop outputting power.

[0034] Preferably, the front wheel assembly 50 includes a front wheel frame, a front wheel axle rotatably disposed on the front wheel frame, and a front wheel disposed on the front wheel axle. The front wheel axle and the front wheel frame are respectively provided with a front brake caliper and a front brake disc.

The rear brake line 703 is connected to the rear brake disc. The rear wheel axle and the motor are connected via a transmission assembly.

[0036] Preferably, the transmission assembly includes a group of sprockets and a chain mounted on the group of sprockets, wherein one sprocket is disposed on the output shaft of the motor and the other sprocket is disposed on the rear wheel shaft.

[0037] Preferably, the rear brake disc and the other sprocket are respectively located on both sides of the rear wheel. The two sides are separately arranged, which is convenient for installation and is conducive to the utilization of the installation opening space.

[0038] Preferably, the rear wheel frame includes a left frame body and a right frame body which are spaced apart at the rear of the pedal assembly 10, the left frame body and the right frame body are spaced apart to form a mounting opening, a fender is provided on the front side of the mounting opening, the motor is arranged in the mounting opening below the fender, and the rear wheel axle is rotatably connected to the rear side of the mounting opening.

[0039] It should be noted that the finger dial, the bicycle bell, etc. and the brake 706 are respectively located on the two sides of the handle 601, so that braking and other control actions can be cooperatively operated by both hands, making the operation more convenient. In addition, by arranging a pressure sensor 709 connected to the controller in the installation cavity 700, when the articulated arm 7061 rotates, it abuts against the pressure sensor 709 and transmits a pressure signal to the controller, and the controller controls the motor to stop rotating.
