DETAILED DESCRIPTION

[0019] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention.

[0022] The electric tricycle intelligent mountain power system of the present invention mainly includes an instrument 1, a shift control group, a power battery pack 7 and a brake group; the instrument 1 has a predetermined operating size and is provided with a display screen for displaying corresponding data, and the instrument 1 is connected to the vehicle handle; a predetermined operating distance is left between the shift control group and the instrument 1, and the brake group is connected through a shift zipper 6; a predetermined operating distance is left between the brake group and the instrument 1, and the brake group is connected to the instrument 1 and the power battery pack 7 through a cable 3.

[0023] The shift control group includes a shift handle 4 and a shift handle bracket 5. The shift handle bracket 5 has a predetermined operating size and load-bearing space, and is connected to the frame 18-4 body, and can perform corresponding positioning and load-bearing operations; the shift handle 4 is placed on the working surface of the shift handle bracket 5, and is connected to the brake group through the shift puller 6.

[0024] The power battery pack 7 is provided with a battery temperature sensor 8, which can detect the operating temperature of the power battery pack 7 in real time, and the battery temperature sensor 8 is connected to the instrument 1 through a cable 3. The sensor control module includes a wiring waterproof box 9, a Bluetooth module 10 and a controller 12; the wiring waterproof box 9 has a predetermined accommodation capacity, and the controller 12, the power battery pack 7, the battery temperature sensor 8 and the connecting plug of the instrument 1 are all placed in the wiring waterproof box 9; the Bluetooth module 10 is connected to the controller 12 through a plug and fixed on the support 11 of the controller 12.

[0025] The brake assembly includes a power motor 13, an electromagnetic brake 14, a gearbox 16, a brake pedal 17 and a brake sensor 18; the power motor 13 is assembled on the gearbox 16, and the gearbox 16 is connected to the shift handle 4 via the shift lock 6; the electromagnetic brake 14 is connected to the power motor 13, the brake pedal 17 is connected to the brake sensor 18, and the brake sensor 18 is connected to the controller 12 via a cable 3.

[0026] The power motor 13 includes a power motor housing 13-1, a power motor transmission shaft 13-2 and a power motor rear cover 13-3; the electromagnetic brake 14 is fixed on the power motor housing 13-1 and the power motor transmission shaft 13-2, and the power motor rear cover 13-3 is assembled on the power motor housing 13-1 to protect the electromagnetic brake 14 and the power motor transmission shaft 13-2.

[0027] The controller 12 controls the operation of the power motor 13 and the electromagnetic brake 14 through the signal line 13-4; the battery temperature sensor 8 is attached to the battery surface by pasting, and the controller 12 monitors the battery and motor temperatures in real time through the battery temperature sensor 8 and the motor internal temperature sensor.

[0028] The brake assembly is provided with a sensor fixing bracket 18-3, and the sensor fixing bracket 18-3 is welded to the frame 18-4. The brake sensor 18 is assembled on the sensor fixing bracket 18-3 by two upper and lower fixing nuts 18-1. The brake sensor 18 is provided with threads, and the height of the brake sensor 18 can be adjusted by adjusting the position of the fixing nuts 18-1.

[0029] The controller 12 and the instrument 1 are connected via a twisted pair cable inside a cable 3, and data transmission is performed via RS485 communication.

[0030] The vehicle handle is further provided with a steep slope descent switch 2, and the steep slope descent switch 2 is connected to the brake assembly through a cable 3.

[0031] In a further preferred embodiment, Figure 1As shown, the power motor 13, controller 12, 96V power battery pack 7, battery temperature sensor 8, and instrument 1 are connected through the main cable 3, and the connecting plug is placed in the wiring waterproof box 9, and V0 grade flame retardant material is used. The 96V power battery pack 7 provides a high-voltage energy platform for the power motor 13 and the controller 12 to improve the endurance. The battery temperature sensor 8 is pasted on the surface of the battery. The controller 12 monitors the battery and motor temperature in real time through the battery temperature sensor 8 and the internal temperature sensor of the motor. If the first limit is exceeded, the motor power output is limited to reduce the temperature rise. If the second limit is exceeded, the power is cut off and the work is stopped, and the temperature is automatically restored after the temperature drops. The controller 12 and the instrument 1 are connected through the twisted pair inside the cable 3, and data is transmitted through the RS485 communication method. It has strong anti-interference ability and can display the faults, speed, temperature and other parameters of the motor electronic control.

[0032] like Figure 2 As shown, the electromagnetic brake 14 is fixed on the power motor housing 13-1 and the power motor transmission shaft 13-2, and the power motor rear cover 13-3 is assembled on the power motor housing 13-1 to protect the electromagnetic brake 14 and the power motor transmission shaft 13-2. The vehicle controller 12 controls the power motor 13 and the electromagnetic brake 14 to work through the signal line 13-4.

[0033] like Figure 3 As shown, the sensor fixing bracket 18-3 is welded on the vehicle frame 18-4, and the brake sensor 18 is assembled on the sensor fixing bracket 18-3 by two upper and lower fixing nuts 18-1. The brake sensor 18 has threads, and the sensor height can be adjusted by adjusting the position of the fixing nuts 18-1, so as to realize the time difference and sensitivity of the brake sensor 18 sensing the braking action after the driver steps on the brake pedal 17.

[0034] pass Figure 2 and Figure 3 In the structure involved, when the driver steps on the brake pedal 17 to brake, the brake sensor 18 senses the braking action and transmits the signal to the controller 12 through the cable 3 to control the power motor 13 to perform electromagnetic auxiliary braking and kinetic energy recovery. The controller 12 also detects the speed of the power motor 13, and determines whether the speed drop of the power motor 13 meets the requirements according to the program. If it is determined that the speed drop is slow and the vehicle speed drops slowly, the electromagnetic brake 14 is immediately controlled to engage the auxiliary brake to achieve three-level braking. The three-level braking method increases the braking safety performance while reducing the wear of the brake pads and improving the brake life. The timing of turning on the auxiliary brake by the controller 12 can be adjusted by adjusting the distance between the brake sensor 18 and the brake pedal 17. The closer the distance, the earlier the auxiliary brake mode starts, and the farther the distance, the later the auxiliary brake mode starts.

[0035] The controller 12, the power motor 13, and the electromagnetic brake 14 also have an automatic auxiliary brake function. On an uphill road, when the reverse switch is not turned on, the controller 12 monitors the steering of the power motor 13 in real time. When the forward steering turns to reverse, it is judged that the vehicle enters the rear sliding slope condition, and the power motor 13 immediately performs electromagnetic braking to control the vehicle's sliding speed, and judges whether the speed reduction of the power motor 13 meets the requirements according to the program. If it is judged that the speed becomes faster and the vehicle speed is getting faster and faster, the electromagnetic brake 14 is immediately controlled to engage the auxiliary brake to achieve the second-level anti-slip braking. On a downhill road, the above function is manually turned on and off through the steep slope descent switch 2. When it is actively turned on and the vehicle slides down, the controller 12 controls the power motor 13 to perform electromagnetic braking, and according to the change in vehicle speed, the electromagnetic brake 14 is turned on and off to achieve the second-level steep slope descent braking.

[0036] The power motor 13 is mounted on the gearbox 16, and the gearbox 16 is connected to the gearshift handle 4 through the gearshift zipper 6, and the gearshift handle 4 is mounted on the gearshift handle bracket 5. The gearshift handle bracket 5 has a groove to prevent accidental gear shifting. Under light load conditions, the gearbox 16 is changed to a high-speed 1:10 transmission system through the gearshift handle 4. At this time, the vehicle speed is fast and the load capacity is weak. Under heavy load conditions, the gearbox 16 is changed to a climbing gear using a 1:32 transmission system through the gearshift handle 4. The torque output is increased by 3.2 times, and the climbing ability is increased by 3.2 times. The gearshift handle 4 is placed in the groove of the gearshift handle bracket 5 to prevent the vehicle from automatically shifting out of gear under accidental heavy load conditions. The tire 15 adopts an explosion-proof tire 15 with a steel wire structure, and the tread is flat, which increases the contact area with the ground, increases the friction, and improves the climbing ability.

[0037] The Bluetooth module 10 is connected to the controller 12 through a plug and fixed on the bracket 11 of the controller 12. The external Bluetooth module 10 is adopted, and the cost of damage repair is low. The driver uses the Bluetooth of the smart phone to connect to the Bluetooth module 10, that is, to the controller 12, and checks the vehicle operation status through the mobile phone APP to provide data for vehicle maintenance and repair. The controller 12 parameters can also be modified through the mobile phone to adjust the vehicle power performance and various functional surface shapes, increase the release area from the ground, increase friction, and improve climbing ability.

[0038] The Bluetooth module 10 is connected to the controller 12 through a plug and fixed on the bracket 11 of the controller 12. The external Bluetooth module 10 is adopted, and the cost of damage repair is low. The driver uses the Bluetooth of the smart phone to connect to the Bluetooth module 10, that is, to the controller 12, and checks the vehicle operation status through the mobile phone APP to provide data for vehicle maintenance and repair. The controller 12 parameters can also be modified through the mobile phone to adjust the power performance and various functions of the whole vehicle.

[0039] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
