The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0026] First embodiment

[0027] like Figure 1 and Figure 4 As shown, the cargo box heating system 100 includes a motor 110, an all-in-one controller 120, a water pump 130, a first three-way valve 140, a first solenoid valve 150, a cargo box heating module 160, and a second three-way valve 170. The cargo box heating module 160 includes a cargo box heating water tank 161. The motor 110, the all-in-one controller 120, the water pump 130, the first three-way valve 140, the first solenoid valve 150, the cargo box heating water tank 161 and the second three-way valve 170 are connected in a circular manner in sequence, and the cargo box heating module 160 is connected to the heating air duct 310 at the bottom of the cargo box 300.

[0028] The medium flowing in the cargo box heating system 100 may be liquid or gas, and the liquid includes cooling oil. After the cooling oil exchanges heat between the motor 110 and the all-in-one controller 120, the heat energy generated is transmitted to the heating air duct 310 at the bottom of the cargo box 300 to heat the cargo box 300. Specifically, the cooling oil is heated and flows out through the motor 110 and the all-in-one controller 120 in sequence, and flows to the first three-way valve 140 through the water pump 130. When the cargo box 300 needs to be heated, the driver turns on the cargo box heating switch in the cab. At this time, the all-in-one controller 120 opens the first solenoid valve 150 and closes the second solenoid valve 180. At this time, the heated cooling oil flows to the cargo box heating water tank 161 and returns to the motor through the second three-way valve 170, which not only realizes the recycling of the cooling oil, but also the heat energy generated can heat the cargo box 300, achieving the effects of energy saving, emission reduction, energy saving and environmental protection.

[0029] refer to Figure 1 The motor 110 is the core power source of the pure electric mining vehicle, responsible for converting electrical energy into mechanical energy and providing the required power for the vehicle. Through the drive of the motor 110, the mining vehicle can realize forward, backward, acceleration, deceleration and other actions to meet the needs of mine transportation. The all-in-one controller 120 is a product that integrates multiple control modules. It realizes multiple functions through intelligent control and plays a vital role in the operation and performance of the mining vehicle, including realizing driving force control, battery protection, and improving system efficiency. The motor 110 and the all-in-one controller 120 are respectively provided with cooling channels, that is, the cooling oil passes through the cooling channels in the motor 110 and the all-in-one controller 120 in turn, which not only realizes the cooling of the motor 110 and the all-in-one controller 120, but also the cooling oil heats the cargo box 300 after heat exchange. Compared with the configuration method of adding a brake resistor system in the prior art, it reduces the cost and ensures the reliability of the whole vehicle operation.

[0030] like Figure 4 As shown, the cargo box heating module 160 further includes a housing 163, and the cargo box heating water tank 161 is disposed inside the housing 163. By arranging the housing 163 outside the cargo box heating water tank 161, the cooling oil exchanged in the cargo box heating water tank 161 can be reasonably utilized, and the cargo box heating water tank 161 can be protected.

[0031] like Figure 1 and Figure 4 As shown, the cargo box heating module 160 further includes a fan 162 , and the fan 162 is disposed inside the shell 163 . The fan 162 is disposed corresponding to the cargo box heating water tank 161 .

[0032] The fan 162 can also be controlled by a switch in the cab. After the fan 162 is started, it not only cools down the cooling oil exchanged in the cargo box heating water tank 161 and re-transports it to the cooling channels in the motor 110 and the all-in-one controller 120 to cool down the motor 110 and the all-in-one controller 120, but also transfers the heat of the heat-exchanged cooling oil to the bottom of the cargo box 300 to heat the cargo box 300.

[0033] like Figure 1 and Figure 4 As shown, the cargo box heating module 160 further includes a water inlet pipe 164 and a water outlet pipe 165, wherein the water inlet pipe 164 is connected between the first solenoid valve 150 and the cargo box heating water tank 161, and the water outlet pipe 165 is connected between the cargo box heating water tank 161 and the second three-way valve 170. The water inlet valve 164 and the water outlet pipe 165 are provided to realize the delivery of cooling oil, and in addition, two adjacent components can also be connected through a pipeline, for example, the all-in-one controller 120 and the water pump 130 are connected through a pipeline.

[0034] like Figure 1 As shown, the cargo box heating system 100 further includes a second solenoid valve 180 and a heat dissipation water tank 190 , and the first three-way valve 140 , the second solenoid valve 180 , the heat dissipation water tank 190 and the second three-way valve 170 are connected in sequence.

[0035] When the cargo box 300 does not need to be heated, the driver turns off the cargo box heating switch in the cab. At this time, the all-in-one controller 120 closes the first solenoid valve 150 and opens the second solenoid valve 180. The heated cooling oil flows to the first tee 140 through the water pump 130, flows to the heat dissipation water tank 190, and returns to the motor 110 and the all-in-one controller 120 after passing through the second tee 170, thereby completing the purpose of cooling the cooling oil. The cooled cooling oil cools the motor 110 and the all-in-one controller 120.

[0036] The first three-way valve 140 and the second three-way valve 170 are both three-way valves. Taking the first three-way valve 140 as an example, they are respectively connected to the water pump 130, the first solenoid valve 150 and the second solenoid valve 180, so that the water pump 130 is respectively connected to the first solenoid valve 150 or the second solenoid valve 180.

[0037] The first solenoid valve 150 and the second solenoid valve 180 are both controlled by switches in the cab, and the opening and closing of the valves are controlled by electromagnetic force, thereby controlling the flow of cooling oil.

[0038] like Figure 1 As shown, the cargo box heating system 100 further includes a cooling fan 191 , and the cooling fan 191 is disposed corresponding to the cooling water tank 190 .

[0039] The cooling fan 191 can also be turned on and off by a switch in the cab. When the cargo box 300 does not need to be heated, the cooling fan 191 is turned on and blows toward the cooling water tank 190 to speed up the cooling of the heat exchange cooling oil passing through the cooling water tank 190, thereby cooling the motor 110 and the all-in-one controller 120.

[0040] The working method of the cargo box heating system 100 is as follows:

[0041] refer to Figure 1 After the vehicle is running, the cooling oil is heated by the motor 110 and the all-in-one controller 120 and flows out through the water pump 130 to the first three-way valve 140 .

[0042] refer to Figure 2 When the cargo box 300 does not need to be heated, the driver turns off the cargo box heating switch in the cab. At this time, the all-in-one controller 120 closes the first solenoid valve 150 and opens the second solenoid valve 180, and at the same time controls the cooling fan 191 to turn on. The heated cooling oil flows to the first three-way valve 140 through the water pump 130, flows to the cooling water tank 190, and returns to the motor 110 and the all-in-one controller 120 after passing through the second three-way valve 170.

[0043] refer to Figure 3 When the cargo box 300 needs to be heated, the driver turns on the cargo box heating switch in the cab. At this time, the all-in-one controller 120 opens the first solenoid valve 150 and closes the second solenoid valve 180, and starts the fan 162 at the same time. The heated cooling oil flows to the first tee 140 through the water pump 130 and flows to the cargo box heating water tank 161, and returns to the motor through the second tee 170. At this time, the fan 162 transfers the heat of the heat-exchanged cooling oil to the bottom of the cargo box 300 to heat the cargo box 300.

[0044] In summary, the heat energy generated by the motor 110 and the all-in-one controller 120 during vehicle operation is heated to the bottom plate of the cargo box 300, which effectively solves the technical problem that the frozen materials of the pure electric mining vehicle are difficult to remove. The heat energy loss of functional parts is avoided, and the heat energy is reasonably used to achieve the effect of energy saving, emission reduction, energy saving and environmental protection.
