[0033] Please refer to Figure 1 And Figure 8 The utility model provides a kind of braking system 10 for all terrain vehicle 1, which includes brake starting assembly 100, hydraulic control assembly 200 and electric control boost assembly 300.

[0034] Please refer to Figures 3 to 5 Brake starting assembly 100 includes rotatable pedal mechanism 120 and angle sensor 130, and angle sensor 130 is configured to detect the angle of rotation of pedal mechanism 120.Pedal mechanism 120 includes pedal 121 for stepping and connecting rod 122 connected with pedal 121, and push rod 123 acting on hydraulic control assembly 200 is connected on connecting rod 122.Angle sensor 130 can be any sensor capable of measuring the angle of rotation of pedal mechanism 120, such as potentiometer, ultrasonic angle sensor 130, optical fiber angle sensor 130, etc., and potentiometer is used in the embodiment.The angle of rotation of pedal mechanism 120 detected by angle sensor 130 can be fed back to various control systems and control corresponding components to achieve different functions, and the control system can be, for example, braking system 10, energy recovery system, vehicle control system, etc.In an embodiment, the angle of rotation of pedal mechanism 120 detected by angle sensor 130 is fed back to energy recovery system, and when stepping on pedal 121, all terrain vehicle 1 will convert part of kinetic energy into electrical energy storage.By accurately measuring the opening of pedal 121, controlling energy recovery can make the energy recovery process more smooth, and the intensity of energy recovery more delicate, which improves the jerk caused by sudden change of recovery intensity.

[0035] Please refer to Figure 1The hydraulic control assembly 200 comprises a master cylinder 210 and a plurality of wheel brakes 230 in communication with the master cylinder 210 through a hydraulic pipeline 220. The wheel brakes 230 can be disc brakes or drum brakes, which are not limited. Disc brakes are used in the embodiment. The wheel brakes 230 comprise a front left wheel brake 231 installed on the front left wheel, a rear right wheel brake 232 installed on the rear right wheel, a front right wheel brake 233 installed on the front right wheel, and a rear left wheel brake 234 installed on the rear left wheel. The master cylinder 210 comprises a piston rod 213, a first chamber 211, and a second chamber 212. The first chamber 211 and the second chamber 212 are independent of each other and are not limited in position. As long as the oil is returned or discharged at the same time when the piston rod 213 is extended or retracted, the connecting piston rod 213 of the brake starting assembly 100 is connected with the piston rod 213. Specifically, the push rod 123 in the pedal mechanism 120 is connected with the piston rod 213. When the driver steps on the pedal 121, the pedal 121 drives the connecting rod 122 to rotate, the connecting rod 122 pushes the push rod 123 to drive the piston rod 213 to extend or retract, and the brake system 10 starts to work. The all-terrain vehicle 1 is slowed down or stopped, and the size of the braking force can be controlled by adjusting the force and depth of stepping on the pedal 121, so that smooth deceleration or emergency braking is realized.

[0036] Please refer to Figures 6 to 8 The electric control and power assisting assembly 300 comprises an energy storage unit 330, an electric motor 320, and an electric control unit 310. The first chamber 211 is in communication with the front left wheel brake 231 and the rear right wheel brake 232 through the energy storage unit 330, and the second chamber 212 is in communication with the front right wheel brake 233 and the rear left wheel brake 234 through the energy storage unit 330. The above technical solution can realize that when the pedal mechanism 120 is stepped on for braking operation, the hydraulic oil of the first chamber 211 is injected into the front left wheel brake 231 acting on the front left wheel and the rear right wheel brake 232 acting on the rear right wheel, and the hydraulic oil of the second chamber 212 is injected into the front right wheel brake 233 acting on the front right wheel and the rear left wheel brake 234 acting on the rear left wheel. The setting realizes that the hydraulic oil of the first chamber 211 of the master cylinder 210 simultaneously acts on the front left wheel and the rear right wheel, and the hydraulic oil of the second chamber 212 simultaneously acts on the front right wheel and the rear left wheel. Thus, even in the case of failure of one chamber, the brake system 10 can still provide 50% of the braking force, and the vehicle braking balance can be realized, which can improve the technical problem that the all-terrain vehicle 1 is prone to fishtailing and side slipping during braking.

[0037] Please refer to Figures 7 to 8The motor 320 and the energy storage unit 330 are in transmission connection, the motor 320 includes a motor shaft 321 capable of linear motion, the energy storage unit 330 includes a plunger 338 and a third chamber 339 in sliding connection with the plunger 338, and the third chamber 339 is communicated with the front left wheel brake 231, the rear right wheel brake 232, the front right wheel brake 233 and the rear left wheel brake 234. The motor shaft 321 is connected with the plunger 338 to push the plunger 338 to perform telescopic motion, and the hydraulic oil in the third chamber 339 is injected into the front left wheel brake 231, the rear right wheel brake 232, the front right wheel brake 233 and the rear left wheel brake 234, so that the braking of the wheel 15 is realized. The electric control unit 310 is in signal connection with the angle sensor 130 and the motor 320. The electric control unit 310 is configured to generate a control instruction to drive the motor 320 to act on the energy storage unit 330 based on the detection signal of the angle sensor 130. Specifically, the electric control unit 310 can determine the operation intention of the driver, such as the force and speed of stepping on the pedal 121, according to the signal detected by the angle sensor 130, accurately control the motor 320, so that the energy storage unit 330 can quickly establish the required pressure, reduce the operation force of the driver, and provide power assistance for braking. The structure of the electric control power assistance assembly 300 is compact, the demand for the installation space of the all-terrain vehicle 1 is reduced, and the utilization rate in the all-terrain vehicle 1 is improved.

[0038] Please refer to Figures 6 to 7 In an embodiment of the present application, the energy storage unit 330 includes a cylinder body 331 and a first oil inlet channel 332, a second oil inlet channel 333, a front left oil outlet 334, a rear right oil outlet 335, a front right oil outlet 336 and a rear left oil outlet 337 arranged on the cylinder body 331, the first oil inlet channel 332 is connected with the first chamber 211, the first oil inlet channel 332 is communicated with the front left oil outlet 334 and the rear right oil outlet 335, the second oil inlet channel 333 is connected with the second chamber 212, the second oil inlet channel 333 is communicated with the front right oil outlet 336 and the rear left oil outlet 337, the front left oil outlet 334 is communicated with the front left wheel brake 231, the rear right oil outlet 335 is communicated with the rear right wheel brake 232, the front right oil outlet 336 is communicated with the front right wheel brake 233, and the rear left oil outlet 337 is communicated with the rear left wheel brake 234. It should be noted that the communication between the third chamber 339 and the front left oil outlet 334, the rear right oil outlet 335, the front right oil outlet 336 and the rear left oil outlet 337 is controlled by a plurality of electromagnetic valves, the plurality of electromagnetic valves are controlled by the electric control unit 310, and the installation positions of the plurality of electromagnetic valves and the control relationship with the electric control unit 310 are not the main improvement points of the present application, which can refer to the prior art, for example Figure 7 and Figure 8 The present application adopts the scheme shown in the prior art, and will not be described in detail.

[0039] Please refer to Figure 7In an embodiment of the present application, the electric control power assisting assembly 300 further comprises an anti-lock braking unit 340, and a wheel speed signal sensor is arranged on each wheel 15, which can be a Hall sensor, a magneto-electric sensor or an optical encoder, and the like, and the present application is not limited in this regard. Each wheel speed signal sensor is signal connected to the electric control unit 310, and the electric control unit 310 controls the anti-lock braking system 10 to work through the signals fed back by each wheel speed signal sensor. The electric control unit 310 comprises a one-way valve 341 and a pressure sensor 342 through the anti-lock braking unit 340. The signals detected by the wheel speed signal sensor generate control instructions to control the one-way valve 341, and the pressure sensor 342 monitors the hydraulic pressure in the energy storage unit 330. When the wheel 15 is detected to have a risk of locking, the pressure is quickly released, and the braking pressure is increased when the risk of locking is removed, and the cycle is repeated, thereby adjusting the braking force on the wheel 15, realizing the anti-lock function of the wheel 15 in the braking process, and improving the driving safety. It should be noted that the one-way valve 341 and the pressure sensor 342 are integrated on the energy storage unit 330, without occupying other installation space, thereby improving the space utilization rate of the all-terrain vehicle.

[0040] In an embodiment of the present application, the electric control unit 310 generates control instructions to the four wheels 15 through the signals detected by the wheel speed signal sensor. The wheel speed signal sensor is used to detect the wheel speed of the wheel 15 in real time, and the electric control unit 310 judges the dynamic state (such as steering braking or straight-line braking) of the vehicle and the risk of locking through the values fed back by the wheel speed signal sensor of each wheel 15, and adjusts the braking force of each wheel 15 according to different states and locking risk conditions, so as to realize the braking force distribution of the wheel 15, and reduce the risk of wheel 15 locking, side slipping and vehicle body instability. It should be noted that the analysis and calculation method of the electric control unit 310 for signals is not the main point of the present application, and the conventional means in the art can be referred to, and the present application is not limited in this regard.

[0041] In an embodiment of the present application, the electric control power assisting assembly 300 further comprises an electronic parking brake unit. The electronic parking brake unit realizes the parking brake of the all-terrain vehicle 1 through electronic control, replacing the traditional hand brake lever. The electronic parking brake unit comprises a parking switch (not shown in the figure), and the parking switch can be arranged at any position convenient for the driver to operate, and the present application is not limited in this regard. The parking switch is signal connected to the electric control unit 310, and when the parking switch sends a parking instruction to the electric control unit 310, the electric control unit 310 controls the energy storage element to apply pressure, locking the wheel 15. When the parking switch sends a release parking instruction to the electric control unit 310, the electric control unit 310 controls the energy storage element to release the pressure, releasing the wheel 15. The electronic parking brake unit only needs to press the parking switch to activate or release the parking brake, which is convenient to operate, and can also release the space in the vehicle.

[0042] Please see Figure 7 In one embodiment of this utility model, the electronic power assist assembly 300 further includes a slope sensor 350. The slope sensor 350 can be installed at any position on the all-terrain vehicle 1 that ensures accurate measurement of the tilt angle of the all-terrain vehicle 1, without limitation. In this embodiment, the slope sensor 350 is installed on the energy storage unit 330, saving installation space and facilitating synchronous calibration with the anti-lock braking unit 340, thus saving cost and braking time. The slope sensor 350 is signal-connected to the electronic control unit 310. The electronic control unit 310 generates control commands based on the signals detected by the slope sensor 350 to control the braking force of the electronic parking brake unit. In one embodiment, when the slope sensor 350 detects that the all-terrain vehicle 1 is on a slope of less than or equal to 8°, the braking force required is 8KN. When it is on a slope greater than 8°, the electronic control unit 310 controls the braking force of the electronic parking brake unit to increase to 11KN.

[0043] In one embodiment of this utility model, the electric power steering component 300 is further provided with a stability control unit interface, which is adapted to the electronic stability control unit. This interface can be used to subsequently expand the electronic stability control unit, further improving vehicle driving stability and safety.

[0044] Please see Figure 9 In one embodiment of this utility model, the braking system 10 of the all-terrain vehicle 1 further includes an oil reservoir 400. The oil reservoir 400 is connected to the master cylinder 210 and the energy storage unit 330, respectively, and is used to replenish hydraulic oil to the master cylinder 210 and the energy storage unit 330. The oil reservoir 400 is used to store and supply brake fluid. In this embodiment, the brake fluid is also hydraulic. The oil reservoir 400 needs to supply hydraulic oil to both the master cylinder 210 and the energy storage unit 330 simultaneously. Therefore, the oil reservoir 400 is externally connected to a main oil pipe 410. The main oil pipe 410 is connected to two branch oil pipes 420 through a tee 430. The two branch oil pipes 420 are respectively connected to the third chamber 339 of the master cylinder 210 and the energy storage unit 330. Since the energy storage unit 330 self-pressurizes, causing cavities to easily form in the internal oil circuit, the timely replenishment of hydraulic oil in the energy storage unit 330 by the oil reservoir 400 can compensate for the cavities and ensure the vacuum of the hydraulic unit. This enables rapid pressurization of the energy storage unit 330, ensuring timely pressurization.

The structure of the bottom plate 110 is ingenious and occupies less space, and the rotation angle of the pedal mechanism 120 is detected by the angle sensor 130, which overcomes the difficulty of limited space of the all terrain vehicle 1. The angle of rotation of the pedal mechanism 120 detected by the angle sensor 130 can be fed back to various control systems and control corresponding components to achieve different functions. The control system can be, for example, a brake system 10, an energy recovery system, a vehicle control system, etc. These systems work together to achieve efficient, safe and comfortable operation of the all terrain vehicle 1.
