Description

Technical Field

[0001] This utility model relates to the field of energy vehicle technology, and in particular to an electric mining vehicle. Background Technology

[0002] With the development of new energy technologies, electric mining trucks are becoming increasingly common in mines and mining areas. Mining trucks typically have a power system to drive the vehicle, a lifting system for unloading, and a steering system. In current technology, multiple power systems within a mining truck are powered by the same motor. That is, these systems are connected in series, and a failure in one system often renders the others unusable. This reduces the working efficiency of the mining truck. Utility Model Content

[0003] This utility model provides an electric mining truck in which multiple systems can operate independently of each other, and the failure of a single system will not affect other systems, thereby improving the working efficiency of the mining truck.

[0004] This utility model provides an electric mining truck, including a main motor, a gearbox, an auxiliary motor, and a lifting system. The gearbox includes a power input end, a first power output end, and a second power output end. The main motor is connected to the power input end of the gearbox. The first power output end of the gearbox is connected to the input shaft of the auxiliary motor. The second power output end is connected to the lifting system. The output shaft of the auxiliary motor is connected to a drive shaft, and the drive shaft is connected to the wheels.

[0005] Furthermore, the electric mining truck includes a vehicle controller, a main motor controller, and a gearbox controller. The vehicle controller is connected to the main motor controller and the gearbox controller via signals. The main motor controller is connected to the main motor via signals and is used to control the main motor. The gearbox controller is connected to the gearbox via signals and is used to control the gearbox.

[0006] Furthermore, the electric mining vehicle includes an auxiliary motor controller and a steering motor controller. Both the auxiliary motor controller and the steering motor controller are connected to the vehicle controller via signals. The auxiliary motor controller is connected to the auxiliary motor via signals and is used to control the auxiliary motor. The steering motor controller is connected to the steering motor via signals and is used to control the steering motor.

[0007] Furthermore, the auxiliary motor controller and the steering motor controller are integrated into a first control unit.

[0008] Furthermore, the electric mining vehicle includes an air conditioning controller, an air compressor controller, and a DC-DC converter. The air conditioning controller, the air compressor controller, and the DC-DC converter are all connected to the vehicle controller. The air conditioning controller is connected to the air conditioning compressor and the cab heater, and is used to control the air conditioning compressor and the cab heater. The air compressor controller is connected to the brake air compressor, and is used to control the brake air compressor. The DC-DC converter is electrically connected to the battery, and is used to convert the current of the power battery.

[0009] Furthermore, the air conditioner controller, the air compressor controller, and the DC-DC converter are integrated into a second control unit.

[0010] Furthermore, the electric mining vehicle includes a first charging interface, a second charging interface, a high-voltage distribution box, and a battery management system. The first charging interface and the second charging interface are electrically connected to the power battery through the high-voltage distribution box. The battery management system is signal-connected to the vehicle controller and is used to control the power battery.

[0011] Furthermore, the electric mining vehicle includes a pressure sensor, a gear shift lever, an accelerator pedal, and a brake pedal, all of which are connected to the vehicle controller via signals.

[0012] Furthermore, the electric mining vehicle includes a steering motor controller and a steering motor. The steering motor controller is connected to the vehicle controller and is used to control the steering motor.

[0013] In summary, this invention utilizes a main motor, gearbox, and auxiliary motor, with the auxiliary motor's output shaft directly connected to the drive shaft. When the main motor malfunctions, the connection between the main motor and the clutch can be severed, allowing the auxiliary motor to maintain power output and preventing the electric vehicle from slipping on inclines. In other words, in this embodiment, the lifting system and power system are independent. When the main motor malfunctions and lifting is impossible, the auxiliary motor can still provide some power, enabling the vehicle to move. This improves the working efficiency of the mining truck. Furthermore, by allowing the steering system and lifting system to operate independently, the two systems are not affected by each other. Moreover, by separately configuring multiple control devices such as a first control unit, a second control unit, a gearbox controller, and a main motor controller to jointly control all equipment on the vehicle, system stability is improved, maintenance is facilitated, and adaptability is enhanced.

[0014] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0016] Figure 2 The figure shown is a system block diagram of the electric mining truck provided in an embodiment of this utility model. Detailed Implementation

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the present utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] This utility model provides an electric mining truck in which multiple systems can operate independently of each other, and the failure of a single system will not affect other systems, thereby improving the working efficiency of the mining truck.

[0019] Figure 1 The diagram shown is a power transmission route diagram of the electric mining truck provided in an embodiment of this utility model. Figure 2 The diagram shown is a system block diagram of the electric mining truck provided in an embodiment of this utility model. Figure 1 and Figure 2 As shown in the figure, the electric mining truck provided in this embodiment of the present invention includes a main motor 11, a gearbox 12, an auxiliary motor 13, and a lifting system 14. The gearbox 12 includes a power input terminal (not shown), a first power output terminal (not shown), and a second power output terminal (not shown). The main motor 11 is connected to the power input terminal of the gearbox 12. The first power output terminal of the gearbox 12 is connected to the input shaft of the auxiliary motor 13, and the second power output terminal is connected to the lifting system 14. The output shaft 14 of the auxiliary motor 13 is connected to a drive shaft, and the drive shaft is connected to the wheels.

[0020] In this embodiment, the main motor 11, gearbox 12, and auxiliary motor 13 are arranged such that the output shaft 14 of the auxiliary motor 13 is directly connected to the drive shaft. During normal operation of the power system, the power from the main motor 11 is transmitted to the auxiliary motor 13 via the gearbox 12, and together with the auxiliary motor 13, they provide power to the wheels via the drive shaft. On one hand, the electric mining truck can allocate target power according to actual road conditions to adjust the power output of the two motors and save energy; on the other hand, during gear shifting, the auxiliary motor 13 continuously outputs power without interruption. During lifting, the main motor 11 can transmit power to the lifting system 14 via the gearbox 12 to ensure the normal operation of the lifting system 14. When the main motor 11 malfunctions, the connection between the main motor 11 and the gearbox 12 can be disconnected, and the auxiliary motor 13 maintains power output, preventing the electric vehicle from slipping on inclines. In other words, in this embodiment, the lifting system 14 and the power system are independent of each other. When the main motor 11 fails and cannot lift, the auxiliary motor 13 can also take over part of the vehicle's power output, enabling the vehicle to move. This improves the working efficiency of the mining truck.

[0021] It should be noted that the method of adjusting the output power of the dual motors according to road conditions can be based on existing technology, and will not be elaborated here, nor is it the focus of this invention.

[0022] Furthermore, in this embodiment, the auxiliary motor 13 can be connected to the wheel via a drive shaft and a main reducer 15 to transmit power to the wheel. Figure 1 The diagram illustrates the transmission of power to the middle and rear wheels. It is understood that in other embodiments, the drive wheels may not be limited to the middle and rear wheels.

[0023] Further, please continue to refer to Figure 2 In this embodiment, the electric mining vehicle also includes a vehicle controller 20, a main motor controller 31, and a gearbox controller 32. The vehicle controller 20 is connected to the main motor controller 31 and the gearbox controller 32 by signals. The main motor controller 31 is connected to the main motor 11 by signals and is used to control the main motor 11. The gearbox controller 32 is connected to the gearbox 12 by signals and is used to control the gearbox 12.

[0024] Furthermore, the electric mining vehicle also includes a first control unit 33, which includes an auxiliary motor controller 331 and a steering motor controller 32. The auxiliary motor controller 331 and the steering motor controller 32 are integrated within the first control unit 33. Both the auxiliary motor controller 331 and the steering motor controller 32 are electrically connected to the vehicle controller 20. The auxiliary motor controller 331 is signal-connected to the auxiliary motor 13 and is used to control the auxiliary motor 13; the steering motor controller 32 is signal-connected to the steering motor 41 and is used to control the steering motor 41.

[0025] It should be noted that in this embodiment, the auxiliary motor controller 331 and the steering motor controller 32 are integrated into the first control unit 33, which is equivalent to the first control unit 33 being a two-in-one electronic control system.

[0026] In this embodiment, by setting up the steering motor controller 32 and the auxiliary motor controller 331, and by controlling the steering motor 41 through the steering motor controller 32 and the auxiliary motor 13 through the auxiliary motor controller 331, the steering system and the power system are separated and independent of each other. The failure of one system will not affect the normal operation of the other systems.

[0027] The auxiliary motor controller 331 and the steering motor controller 32 are integrated into the first control unit 33. The first control unit 33 is independent of the main motor controller 31 and the gearbox controller 32, which enables the vehicle to be modularly deployed, facilitates maintenance, and improves the compatibility between modules.

[0028] Please continue to refer to Figure 2 In this embodiment, the electric mining vehicle further includes a second control unit 34, which includes an air conditioning controller 341, an air compressor controller 342, and a DC-DC converter 343. The air conditioning controller 341, air compressor controller 342, and DC-DC converter 343 are all connected to the vehicle controller 20. The air conditioning controller 341 is connected to the air conditioning compressor 42 and the cab heater 43, and is used to control these components. The air compressor controller 342 is connected to the brake air compressor 44, and is used to control it. The DC-DC converter 343 is electrically connected to the battery 45, and is used to convert the current from the power battery 51 to charge the battery 45. The battery 45 can supply power to low-voltage electrical appliances (such as 24V appliances) on the vehicle.

[0029] Furthermore, the air conditioning controller 341, the air compressor controller 342, and the DC-DC converter 343 are integrated into the second control unit 34. In other words, the air conditioning controller 341, the air compressor controller 342, and the DC-DC converter 343 essentially form a three-in-one electronic control system.

[0030] That is, in this embodiment, multiple control devices such as the first control unit 33, the second control unit 34, the gearbox controller 32, and the main motor controller 31 are respectively set to jointly complete the control of various devices on the vehicle, which can improve the stability of the system, facilitate maintenance, and have strong adaptability.

[0031] Furthermore, the electric mining vehicle also includes a first charging interface 52, a second charging interface 53, a high-voltage distribution box 54, and a battery management system 55. The first charging interface 52 and the second charging interface 53 are electrically connected to the power battery 51 through the high-voltage distribution box 54. The battery management system 55 is signal-connected to the vehicle controller 20 and is used to control the power battery 51. The power battery 51 can be electrically connected to various devices, such as the main motor 11, auxiliary motor 13, steering motor 41, brake air compressor 44, air conditioning compressor 42, and cab heater 43, through the high-voltage distribution box 54, and supplies power to these devices.

[0032] Furthermore, the electric mining truck also includes a pressure sensor 61, a gear shift lever 62, an accelerator pedal 63, and a brake pedal 64. These components are connected to the vehicle controller 20, enabling the controller to collect signals from each component. Through built-in logic, the various devices on the vehicle are controlled via the first control unit 33, the second control unit 34, the gearbox controller 32, and the main motor controller 31.

[0033] In summary, this invention utilizes a main motor 11, a gearbox 12, and an auxiliary motor 13, with the output shaft 14 of the auxiliary motor 13 directly connected to the drive shaft. When the main motor 11 malfunctions, the connection between the main motor 11 and the clutch can be severed, allowing the auxiliary motor 13 to maintain power output and prevent the electric vehicle from slipping on inclines. In other words, in this embodiment, the lifting system 14 and the power system are independent. When the main motor 11 malfunctions and cannot lift, the auxiliary motor 13 can still provide some of the vehicle's power, enabling the vehicle to move. This improves the working efficiency of the mining truck. Furthermore, by allowing the steering system and the lifting system 14 to operate independently, the two systems are not affected by each other. Furthermore, by separately configuring multiple control devices such as the first control unit 33, the second control unit 34, the gearbox controller 32, and the main motor controller 31 to jointly control all equipment on the vehicle, system stability is improved, maintenance is facilitated, and adaptability is enhanced.
