[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0023] EMBODIMENT

[0024] In combination with the drawings, Figure 1As shown, a mine truck range extending device includes: a vehicle controller 1, a range extending controller 2, an accelerator pedal 3, a brake pedal 4, an emergency switch 5, a vehicle-mounted electrical element 8, a range extender 9 and a power battery 10, etc. The vehicle controller 1 is connected with the accelerator pedal 3, the brake pedal 4 and the range extending controller 2 respectively. The vehicle controller 1 is used to collect the opening degree of the brake pedal 4 and the accelerator pedal 3, obtain the power demand of the mine truck according to the collected opening degree and send it to the range extending controller 2. The range extending controller 2 is also connected with the emergency switch 5, the vehicle-mounted electrical element 8 and the range extender 9, and the range extender 9 is connected with the power battery 10 and the driving motor in turn. The range extending controller 2 is used to receive the power demand signal of the mine truck sent by the vehicle controller and make the range extender output through the received power demand signal. The emergency switch 5 is used to forcibly shut down the range extending controller 2 when the range extender 9 fails, forcing the range extender 9 to stop outputting. The range extender 9 and the power battery 10 are both used to provide power source for the mine truck and can independently provide power source for the mine truck to drive the driving motor.

[0025] The vehicle controller 1 is used to collect the opening degree of the brake pedal 4 and the accelerator pedal 3 to judge the power demand of the mine truck in real time and filter out the short-time power demand.

[0026] The range extending controller 2 is used to receive the power demand signal of the mine truck sent by the vehicle controller and make the range extender output through the received power demand signal.

[0027] The range extender 9 is used to provide power source for the mine truck. The high-power range extender can independently provide sufficient power source for the mine truck.

[0028] The power battery 10 is used to provide power source for the mine truck. The large-capacity battery can independently provide sufficient power source for the mine truck.

[0029] Preferably, the range extending controller 2 and the range extender 9 are in standby state when the power consumption of the power battery 10 reaches the limit value, and at this time the range extender 9 outputs after the accelerator pedal 3 is stepped on and kept for a certain time.

[0030] In a specific embodiment, the accelerator pedal 3 and the brake pedal 4 are connected with the vehicle controller 1 through the hard wire 6 to ensure the reliability of the connection. The range extending controller 2 is connected with the vehicle controller 1, the vehicle-mounted electrical element 8 and the range extender 9 through the CAN line 7. The range extender 9 is connected with the power battery 10 through the high-voltage line. The emergency switch 5 is connected with the range extending controller 2 through the hard wire 6.

[0031] Normally, the range extender 9 is in the shutdown state; when the power battery 10 power consumption to a certain limit, which can be calibrated to 25%, the range extender 9 starts, the range extender controller 2 controls the range extender 9 in standby state, not output. Only when the range extender 9 is in standby state, the accelerator pedal 3 is stepped down and kept for a certain time, the range extender controller 2 controls the range extender 9 to work in the high efficiency zone and output.

[0032] The power battery power does not reach a certain limit before the whole vehicle is in pure electric operation mode, when the power battery power reaches a certain limit, the mine truck is still in pure electric mode under downhill working condition and in flat road low power demand state; only when the mine truck is in climbing and long time power demand flat road state, that is, the accelerator pedal 3 is stepped down and kept for a certain time, the mine truck is in range extending mode, which can solve the problem of overcurrent of mine truck downhill and the problem of insufficient power to climb the slope, affecting the operation efficiency.

[0033] If the range extender 9 fails, the range extender 9 is in long output state, the emergency switch 5 can be used to force the range extender controller 2 to shut down, force the range extender 9 to stop outputting, and achieve the purpose of protecting the power battery 10.

[0034] With the continuous expansion of the market size of mine truck, the range extending mine truck, pure electric mine truck and unmanned mine truck are also constantly emerging, and the problems of mine truck in operation are also exposed, especially the overcurrent problem of range extending mine truck downhill continues to occur. The range extending device for mine truck of the utility model can effectively solve this problem.

[0035] The range extending device for mine truck can control the output of the range extender according to the accelerator pedal opening degree and the demand time, effectively solve the overcurrent problem of mine truck downhill, and control the output power of the range extender according to the accelerator pedal opening degree and the demand time in the application of large range extending large power mine truck. The whole vehicle controller collects the opening degree of the accelerator pedal and the brake pedal in real time, filters out the instantaneous demand, and meets the identification of working condition and application scene. The range extending device for mine truck can effectively improve the application scene of mine truck and improve the operation efficiency. If the range extender control fails and the output is long, the emergency switch can be used to shut down the range extender controller, force the range extender to stop working and protect the power battery from overcurrent and make the mine truck stop.

[0036] In one possible embodiment, a mine truck includes a mine truck range extender device as described above, and the range extender and the power battery can independently provide power sources for the mine truck to drive the motor, respectively. Thus, the energy type power battery can match the small range extender or the large range extender according to the demand, so as to effectively solve the downhill flow problem, and the selection range of the large power small range extender and the large power large range extender is wider, and the application scenario is more comprehensive. The mine truck can select the large power and large range extender scheme, and the two power sources can independently drive the vehicle. When the power battery power is more than 25%, the pure electric scheme can save energy and reduce operation cost. When the power battery power is less than 25%, the pure range extender mode can continue to drive, and emergency shutdown charging is not needed, so that the operation efficiency is greatly improved, the mining capacity is improved, and the comprehensive benefit is greatly increased.

[0037] Although the present application has been described with reference to the explanatory embodiments thereof, the above-described embodiments are merely the preferred embodiments of the present application, and the embodiments of the present application are not limited to the above-described embodiments. It should be understood by those skilled in the art that many other modifications and embodiments can be designed, and these modifications and embodiments will fall within the scope and spirit of the present application.
