Description

Technical Field

[0002] Pure electric wide-body dump trucks are powered by electricity, significantly reducing operating and maintenance costs. This technology is mainly applied to new energy wide-body dump trucks. In specific application scenarios such as ore transportation, pure electric wide-body dump trucks have demonstrated advantages such as long range, low cost, and convenient charging, meeting the transportation needs of specific industries.

[0003] Currently, heating in the cab of pure electric wide-body dump trucks is mostly achieved using PTC heaters. However, PTC heaters consume a lot of power, leading to a reduction in the driving range of electric vehicles. Considering the compact layout of the vehicle, the limited improvement in battery energy density, and cost control, it is not feasible to simply increase the amount of electricity to improve the driving range. As a result, the driving range of pure electric vehicles is severely affected by the PTC heaters in winter, impacting the efficiency of cargo transportation in mining areas. Furthermore, while traditional fuel vehicles can utilize the waste heat from engine exhaust or establish a defrosting facility to heat the cargo box floor, pure electric mining trucks do not have this waste heat.

[0035] See Figures 1 to 4 The pure electric wide-body dump truck provided in this embodiment includes a vehicle body 100 and a diesel heating system 200.

[0036] The vehicle body 100 includes a frame, a cab, and a cargo box 300. The cab is located at one end of the frame, and the cargo box 300 is located at the other end of the frame. The load-bearing plate of the cargo box 300 has a sandwich structure, with an air inlet at one end and an air outlet at the other end. A diesel heating system 200 is located on the frame and has an air outlet 210 and an exhaust pipe 220. The air outlet 210 is connected to the cab, and the exhaust pipe 220 is connected to the air inlet.

[0037] Specifically, the pure electric wide-body dump truck provided in this embodiment is equipped with a diesel heating system 200 on its body 100. When the temperature is low, the diesel heating system 200 can burn diesel fuel to generate heat. The heat generated by the diesel combustion is discharged into the cab through the air outlet 210, thereby heating the cab and preventing the temperature inside the cab from becoming too low.

[0038] Furthermore, the exhaust gas generated by the diesel heating system 200 is discharged through the exhaust pipe 220 into the interlayer of the load-bearing plate of the cargo box 300. The exhaust gas, carrying the residual heat from diesel combustion, enters through the air inlet at one end of the interlayer and flows to the air outlet at the other end for discharge. During this flow, the exhaust gas, carrying residual heat, can heat the load-bearing plate of the cargo box 300, thereby preventing the cargo from sticking to the load-bearing plate of the cargo box 300. This simultaneously heats both the cab and the load-bearing plate of the cargo box 300, making the pure electric wide-body dump truck more convenient to use in winter.

[0039] Furthermore, in this embodiment, the heat generated by diesel combustion can be fully utilized, avoiding energy waste.

[0040] See Figure 2 In this embodiment, the diesel heating system 200 includes a diesel engine 230, a controller, a fan, a damper assembly, and a control panel.

[0041] The diesel engine 230 is mounted on the chassis and is used to generate heat. The controller is also mounted on the chassis. A fan is located in the air outlet duct 210, which discharges air and heat generated by the diesel engine 230 into the duct. The air outlet duct 210 includes a first air outlet and a second air outlet. The first air outlet is connected to the cab, and the second air outlet is connected to the outside air. A damper assembly is located in the air outlet duct 210 and can open and close the first and second air outlets. A control panel is located in the cab and is electrically connected to the controller. The diesel engine 230, fan, and damper assembly are all electrically connected to the controller.

[0042] During use, the driver can input commands through the control panel in the cab. After receiving the commands, the controller controls the opening and closing of the diesel engine 230, the blower and the damper assembly.

[0043] Specifically, the diesel engine 230 is a diesel engine that can obtain energy release and heat by burning diesel. Heat is generated during the combustion of diesel. The fan introduces air, which mixes with the heat generated during the combustion of diesel to form warm air that is discharged to the air outlet 210.

[0044] When the temperature inside the cab is low, the driver can input commands through the control panel, and the controller will control the damper assembly to switch to open the first air outlet and close the second air outlet. At this time, the warm air in the air outlet pipe 210 is discharged into the cab through the first air outlet to heat the cab. The exhaust gas with heat generated by diesel combustion is discharged into the air inlet of the cargo box 300 through the exhaust pipe 220 to heat the load-bearing plate of the cargo box 300.

[0045] When the temperature inside the cab is high enough that heating is not required, and the outside temperature is low enough that the load-bearing plate of the cargo box 300 needs to be heated, the driver inputs a command through the control panel. The controller controls the damper assembly to switch to open the second air outlet and close the first air outlet. At this time, the warm air in the air outlet pipe 210 is discharged to the outside through the first air outlet, and the exhaust gas with heat is discharged into the air inlet of the cargo box 300, thereby heating the load-bearing plate of the cargo box 300.

[0046] As one feasible approach, the second air outlet can be connected to the exhaust pipe 220. With this configuration, when the temperature inside the cab is high and heating is not required, the damper assembly can be controlled to open the second air outlet and close the first air outlet. At this time, the warm air in the exhaust pipe 210 and the heated exhaust gas are both discharged through the exhaust pipe 220 into the air inlet of the cargo box 300. All the heat generated by the diesel engine 230 can be used to heat the load-bearing plates of the cargo box 300, ensuring full utilization of the heat.

[0047] In this embodiment, the diesel-powered heating system 200 further includes a first temperature sensor. The first temperature sensor is located in the air outlet duct 210 and is electrically connected to the controller.

[0048] Specifically, the first temperature sensor can measure the temperature of the warm air in the air duct 210. After the first temperature sensor is electrically connected to the controller, it can send the measured temperature information to the control panel through the controller, so that the driver in the cab can observe the temperature of the warm air in a timely manner, thereby making it easier to judge the operating status of the diesel engine 230 based on the temperature of the warm air.

[0049] In this embodiment, the diesel-powered heating system 200 also includes a filter assembly. The filter assembly is located at the intake end of the diesel engine.

[0050] Specifically, the filter assembly in this embodiment includes an air filter element. The filter assembly can filter the air entering the diesel heating system 200 at the intake end of the diesel engine. The filtered clean air is mixed with heat to form warm air, which is then discharged into the air outlet duct 210. This prevents the air entering the diesel heating system 200 from carrying dust or other particulate matter, thereby ensuring the cleanliness of the warm air discharged into the cab.

[0051] In this embodiment, the diesel heating system 200 also includes a fuel tank 240 and a fuel pump. The fuel tank 240 is mounted on the vehicle frame, one end of the fuel pump is connected to the fuel tank 240, and the other end is connected to the diesel engine 230.

[0052] The fuel tank 240 can store diesel fuel. When the driver starts the diesel engine 230 through the control panel, the fuel pump continuously delivers the diesel fuel in the fuel tank 240 to the diesel engine 230 to ensure the normal operation of the diesel engine 230.

[0053] In this embodiment, the diesel heating system 200 also includes a liquid level sensor. The liquid level sensor is located inside the fuel tank 240 and is electrically connected to the controller.

[0054] The level sensor is installed in the fuel tank 240, which can measure the diesel fuel level in the fuel tank 240 and send the measured level information to the control panel via the controller, so that the driver in the cab can intuitively and promptly view the remaining diesel fuel in the fuel tank 240.

[0055] In this embodiment, the diesel heating system 200 further includes a second temperature sensor. The second temperature sensor is located in the driver's cab and is electrically connected to the controller.

[0056] Combination Figure 5 , Figure 5 This is a schematic diagram of the signal transmission of the diesel heating system in the pure electric wide-body dump truck provided in this embodiment. The second temperature sensor can measure the temperature inside the cab in real time and send the temperature information to the control panel via the controller. When no one is in the cab, after the temperature inside the cab reaches the preset temperature, the control panel triggers the controller, which controls the damper assembly to switch to the second air outlet, stopping the heating of the cab and preventing accidents caused by excessive temperature when no one is in the cab.

[0057] See Figure 3 In this embodiment, the pure electric wide-body dump truck also includes a connecting assembly 250.

[0058] The connecting assembly 250 includes a flexible support and an adapter 251. The flexible support is located at the end of the exhaust pipe 220, and a connecting pipe 254 is provided on the flexible support. One end of the connecting pipe 254 is connected to the exhaust pipe 220. The adapter 251 is located on the flexible support and includes an adapter tube. The adapter tube and the connecting pipe 254 form a sleeve structure. One end of the adapter tube is located inside the connecting pipe 254, and the other end of the adapter tube abuts against and communicates with the air inlet.

[0059] Specifically, the flexible support is located at the end of the exhaust pipe 220. (See also...) Figure 3In this embodiment, the bottom end of the connecting pipe 254 is connected to the exhaust pipe 220, and the connection is locked with clamps and other accessories to ensure a tight seal. The adapter 251 is mounted on an elastic support, and the top opening of the adapter pipe abuts against the air inlet of the cargo box 300's interlayer. When the cargo box 300 flips upward, the elastic support undergoes restorative deformation, and the adapter 251 moves upward under the restorative deformation of the elastic support. When the cargo box 300 flips downward to reset, the cargo box 300 presses down on the opening of the adapter pipe, simultaneously causing the elastic support to be compressed and deformed. The adapter 251 moves downward as the elastic support deforms. This structure ensures that the air inlet of the cargo box 300's interlayer is tightly fitted with the top opening of the adapter pipe, preventing leakage of heated exhaust gas from the joint.

[0060] In this embodiment, the elastic support includes a mounting base 252, a base plate 253, and an elastic element 255.

[0061] One end of the mounting base 252 is connected to the frame, and the other end is connected to the base plate 253. The connecting pipe 254 is located on the base plate 253. The adapter 251 also includes a top plate, which is arranged parallel to the base plate 253. The adapter pipe is located on the top plate and penetrates the top plate. The elastic member 255 is located between the base plate 253 and the top plate. One end of the elastic member 255 is connected to the base plate 253, and the other end is connected to the top plate.

[0062] Specifically, in this embodiment, the mounting base 252 is connected to the vehicle frame by screws. The adapter 251 is a mounting flange, the connecting part at the flange opening of the mounting flange is the top plate, and the extended pipe of the mounting flange is the adapter pipe. The base plate 253 and the mounting flange are spaced apart and parallel to each other. The elastic element 255 is disposed between the base plate 253 and the top plate of the mounting flange and connects the two to fix the position of the mounting flange.

[0063] Furthermore, the transfer pipe is located between the top plate and the bottom plate 253, and the exhaust pipe 220 is sleeved on the outside of the connecting pipe 254 and locked with clamps and other accessories. In this structure, when the cargo box 300 is tilted down, the cargo box 300 presses down on the mounting flange and the air inlet of the cargo box 300 abuts against the flange opening at the top of the mounting flange, compressing the elastic element 255. The mounting flange moves down and compresses the elastic element 255, and the transfer pipe of the mounting flange moves vertically in the connecting pipe 254. The bottom opening of the transfer pipe remains inside the exhaust pipe 220, ensuring that the exhaust gas can be discharged to the air inlet of the cargo box 300 through the mounting flange.

[0064] It should be noted that, in this embodiment, the sleeve structure length of the adapter pipe and connecting pipe 254 is greater than the moving distance of the elastic element 255 pressing down on the cargo box 300. With this structure, after the cargo box 300 flips up and stops pressing down on the mounting flange, during and after the elastic element 255 undergoes restorative deformation causing the mounting flange to move upwards, the connecting pipe 254 can be sleeved outside the adapter pipe, preventing the mounting flange from moving too far upwards and causing the adapter pipe to detach from the connecting pipe 254.

[0065] In addition, in this embodiment, an extension pipe 310 is fixedly welded to the air inlet of the cargo box 300. The top opening of the extension pipe 310 is connected to the interlayer, and the bottom opening of the extension pipe 310 is the air inlet. During the flipping process of the cargo box 300, the bottom opening of the extension pipe 310 abuts against the mounting flange, thereby realizing the transportation of exhaust gas with heat.

[0066] In this embodiment, a guide member 256 is provided on one side of the elastic member 255. The two ends of the guide member 256 are connected to the top plate and the bottom plate respectively, and the guide member 256 slides in cooperation with the top plate and the bottom plate 253.

[0067] Specifically, in this embodiment, the elastic element 255 is a spring, and the guide element 256 is a bolt.

[0068] The system comprises multiple springs and bolts, with the bolts inserted into the springs. These springs and bolts are spaced apart circumferentially along the mounting flange, with the bolt caps located on the top surface of the top plate. The bottom ends of the bolts pass through the base plate 253 and are locked to the bottom surface of the base plate 253 by nuts. In this structure, both the mounting flange and the base plate 253 slide with the bolts. Under external force, the mounting flange and base plate 253 can move closer together while compressing the springs. When no external force is applied, the springs undergo restorative deformation, pushing the mounting flange and base plate 253 away from each other.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
