Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and more specifically, to a new energy special vehicle. Background Technology

[0002] New energy special-purpose vehicles refer to motor vehicles that use new energy sources as their power source and are equipped with special equipment to achieve specific functions. They are mainly used for special transportation, professional operations, and other special purposes. By adding specialized vehicle superstructures to a chassis, these vehicles can be transformed into various functional models such as garbage trucks, road sweepers, high-pressure sweeper trucks, and multi-functional sprinkler trucks.

[0003] New energy special-purpose vehicles are typically equipped with hydraulic systems. These systems achieve centralized control of hydraulic operation modes through a chassis-based multi-function controller. The control process is as follows: the multi-function controller first sends control commands to the oil pump motor controller, which then drives the oil pump motor to operate, thereby controlling the working state of the hydraulic pump and ultimately realizing the various functions of the hydraulic system. However, the current system uses a three-stage series control architecture consisting of the multi-function controller, the oil pump motor controller, and the oil pump motor. This design has the following problems: First, the system has a complex structure and a large number of connecting harnesses; Secondly, the oil pump motor controller usually needs to be located on the side of the chassis subframe; In other words, this not only increases the overall size and weight of the chassis, but also raises manufacturing costs. Utility Model Content

[0025] As described in the background section, new energy special-purpose vehicles are typically equipped with hydraulic systems. The control process involves a multi-function controller first sending control commands to the oil pump motor controller, which then drives the oil pump motor to operate, thereby controlling the working state of the hydraulic pump and ultimately realizing the various functions of the hydraulic system. However, this three-stage series control architecture (multi-function controller, oil pump motor controller, and oil pump motor) presents several problems: First, the system structure is complex, with a large number of connecting harnesses; second, the oil pump motor controller typically needs to be located on the side of the chassis subframe; in other words, this not only increases the overall size and weight of the chassis but also raises manufacturing costs.

[0026] Based on this, please refer to Figures 1-4 The present invention provides a new energy special vehicle 1000, which can effectively improve the aforementioned technical problems. That is, it can reduce the overall size and weight of the chassis 100 and reduce manufacturing costs. The new energy special vehicle 1000 will be described in detail below.

[0027] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the new energy special vehicle 1000 provided in this embodiment, combined with... Figure 1 The new energy special vehicle 1000 includes a chassis 100, a special vehicle superstructure 200, and a hydraulic system (not shown in the figure). The special vehicle superstructure 200 and the hydraulic system are both mounted on the chassis 100. The hydraulic system is used to drive the special vehicle superstructure 200 to perform superstructure actions.

[0028] It should be noted that in this embodiment, the special vehicle mounted on the 200 is specifically a garbage compression device. Therefore, the new energy special vehicle 1000 provided in this embodiment can be understood as a new energy garbage truck. Of course, in other embodiments, the special vehicle mounted on the 200 can also be a watering device, a sweeping device, or other equipment for other operational purposes, which will not be elaborated here.

[0029] For details, please refer to Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of the chassis 100 provided in this embodiment. Figure 3 This is a partial structural diagram of the chassis 100 provided in this embodiment. (In conjunction with...) Figures 1-3 The chassis 100 includes a frame 10, a superstructure oil pump motor 20, and a multi-function controller 30, with the superstructure oil pump motor 20 and the multi-function controller 30 spaced apart on the frame 10. The special vehicle superstructure 200 includes multiple working cylinders, which are mounted on the frame 10. The hydraulic system includes a hydraulic pump connected to the superstructure oil pump motor 20, which drives the hydraulic pump to enable the multiple working cylinders to perform superstructure actions.

[0030] The multi-function controller 30 includes a vehicle control module 35 and an oil pump motor control module 32 connected to each other, and integrates the vehicle control module 35 and the oil pump motor control module 32. The oil pump motor control module 32 is electrically connected to the upper-mounted oil pump motor 20. The multi-function controller 30 is used to control the upper-mounted oil pump motor 20 while controlling the new energy special vehicle 1000.

[0031] Understandably, by integrating the vehicle control module 35 and the oil pump motor control module 32 through the all-in-one controller 30, the upper-mounted oil pump motor 20 can be directly driven to operate, thereby controlling the working state of the hydraulic oil pump. This eliminates the need for a separate oil pump motor controller on the frame 10, as is done in the prior art. It directly eliminates the need for the oil pump motor controller and its mounting bracket, saving installation space on the chassis 100, simplifying the system structure, and reducing the number of connecting harnesses. This reduces the overall size and weight of the chassis 100 and lowers manufacturing costs.

[0032] It should be noted that in this embodiment, the upper oil pump motor 20 is specifically a permanent magnet synchronous motor; of course, in other embodiments, the upper oil pump motor 20 may also be other types of motors.

[0033] Furthermore, the new energy special vehicle 1000 also includes a cab 50, which is mounted on the frame 10. The multi-function controller 30 is mounted on the front beam of the frame 10 and located below the cab 50. The upper structure oil pump motor 20 is located behind the cab 50.

[0034] It should be noted that the "below" and "rear" mentioned above refer to the positions that those skilled in the art can clearly know during normal driving or when the new energy special vehicle 1000 is set up in its normal state.

[0035] By placing the multi-function controller 30 at the front beam of the frame 10, the spatial layout of the chassis 100 is optimized, and the installation stability of the multi-function controller 30 is improved. Furthermore, placing it below the cab 50 also improves the installation environment of the multi-function controller 30, providing some waterproofing and dustproofing. In addition, placing the superstructure oil pump motor 20 behind the cab 50 also optimizes the spatial layout of the chassis 100 and facilitates connection with structures such as hydraulic oil pumps, shortening the connection path and further reducing costs.

[0036] Combination Figure 3 The chassis 100 also includes a motor connector 40, which is integrated with both the upper-mounted oil pump motor 20 and the multi-function controller 30. Specifically, in this embodiment, the oil pump motor control module 32 is electrically connected to the motor connector 40.

[0037] As is easily understood, the all-in-one controller 30 is directly electrically connected to the upper-mount oil pump motor 20 through the integrated motor connector 40, directly driving the upper-mount oil pump motor 20 to operate, thereby controlling the working state of the hydraulic oil pump to realize the various functions of the special vehicle hydraulic system, thereby further reducing the number of connecting harnesses and reducing manufacturing costs.

[0038] For details, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of the motor connector 40 provided in this embodiment, combined with... Figures 2-4 The motor connector 40 includes a first plug-in 41, a high-voltage wiring harness 42, and a second plug-in 43 connected in sequence. The first plug-in 41 is electrically connected to the upper-mount oil pump motor 20, and the second plug-in 43 is electrically connected to the multi-function controller 30. It is easy to understand that by providing the first plug-in 41 and the second plug-in 43, it is convenient to plug and connect with the upper-mount oil pump motor 20 and the multi-function controller 30, thus improving assembly efficiency.

[0039] To further improve assembly efficiency, in this embodiment, the upper oil pump motor 20 is provided with a first AC power input interface 21, and the first plug 41 is plugged into the first AC power input interface 21; the multi-function controller 30 is provided with a second AC power input interface (not shown in the figure), and the second plug 43 is plugged into the second AC power input interface.

[0040] It should be noted that, specifically in this embodiment, the first AC power input interface 21 is located at the bottom of the upper oil pump motor 20; similarly, the second AC power input interface is located at the bottom of the multi-function controller 30. That is to say, the first connector 41 and the second connector 43 are respectively inserted into the bottom of the upper oil pump motor 20 and the multi-function controller 30, which improves the sealing and protection effect by adjusting the installation position of the connectors.

[0041] Of course, in some other embodiments, the first AC power input interface 21 may also be located on the side or top of the upper oil pump motor 20, and similarly, the second AC power input interface may also be located on the side or top of the multi-function controller 30.

[0042] Please continue to combine Figure 3 The chassis 100 also includes a battery pack 60, which is mounted on the frame 10; the multi-function controller 30 also includes a battery control module 31, which is electrically connected to the battery pack 60. Understandably, the battery control module 31 can control the battery pack 60, including the distribution and management of electrical energy.

[0043] Furthermore, the oil pump motor control module 32 includes a current sensor, a voltage sensor, a temperature sensor, and an IGBT power unit. It can acquire data such as the current, voltage, and temperature of the upper-mount oil pump motor 20 and adjust the operating state of the upper-mount oil pump motor 20 according to actual conditions. This embodiment fully utilizes the existing architecture of the all-in-one controller 30, integrating the control processing module for the upper-mount oil pump motor 20, the heat dissipation management program, and software algorithms into the all-in-one controller 30, thereby reducing the size and weight of the chassis 100.

[0044] Furthermore, the chassis 100 also includes a chassis drive motor 70, which is mounted on the frame 10. The battery pack 60 provides power to the chassis drive motor 70 to drive the wheels, thereby enabling the overall movement of the new energy special vehicle 1000.

[0045] In order to better control the chassis drive motor 70 and further integrate the relevant structural layout to optimize the overall volume and weight of the chassis 100, in this embodiment, the multi-in-one controller 30 also includes a drive motor control module 33, which is electrically connected to both the battery control module 31 and the chassis drive motor 70.

[0046] Optionally, the all-in-one controller 30 also includes a pre-charge circuit 34, which is electrically connected to the battery control module 31. The chassis drive motor 70 is electrically connected to the pre-charge circuit 34 through the drive motor control module 33, and the superstructure oil pump motor 20 is electrically connected to the pre-charge circuit 34 through the motor connector 40.

[0047] It should be noted that in this embodiment, the existing main power circuit for motor control is replaced with a high-voltage pre-charge circuit 34. This pre-charge circuit 34 includes components such as a pre-charge resistor, a pre-charge contactor, and a main positive contactor. In other words, the upper-mount oil pump motor 20 and the chassis drive motor 70 in this embodiment share the same pre-charge circuit 34, eliminating the previously separately set upper-mount high-voltage circuit. This further saves on the number of related wiring harnesses, reduces material and assembly costs, and allows for unified management of the high-voltage power-on and power-off processes. Therefore, this new energy special vehicle 1000, by fully utilizing the existing architecture of the all-in-one controller 30, integrates various components and connection structures of the system, thereby achieving the goal of reducing the overall size and weight of the system.

[0048] Please continue to combine Figure 3 To facilitate the control of the new energy special vehicle 1000 in completing specific operational tasks of the superstructure (such as lifting, compression, or unloading), the chassis 100 also includes a superstructure motion controller 81 and a CAN bus 82. The superstructure motion controller 81 is electrically connected to the multi-function controller 30 via the CAN bus 82. In this embodiment, the CAN bus 82 is electrically connected to the vehicle control module 35 in the multi-function controller 30 to obtain the operating condition data of the superstructure oil pump motor 20 and control various operating modes of the superstructure oil pump motor 20.

[0049] Specifically, the all-in-one controller 30 sends control command settings via the CAN bus 82. These settings are provided by the upper structure motion controller 81 and include: required operating speed, required operating torque, maximum allowable operating speed, maximum allowable operating torque, and speed acceleration. For example, the upper structure oil pump motor 20 controls the displacement of the hydraulic oil pump by controlling its speed. Furthermore, the upper structure oil pump motor 20 feeds back real-time operating data to the all-in-one controller 30 via the CAN bus 82. This data includes: fault alarms and their levels, actual operating speed, actual operating torque, bus voltage, and bus current, thereby better realizing different upper structure operation modes.

[0050] In summary, the embodiments of this utility model provide a new energy special vehicle 1000, which includes a chassis 100, a special vehicle superstructure 200, and a hydraulic system. The chassis 100 includes a frame 10, a superstructure oil pump motor 20, and a multi-function controller 30, with the superstructure oil pump motor 20 and the multi-function controller 30 spaced apart on the frame 10. The special vehicle superstructure 200 includes multiple working cylinders, which are disposed on the frame 10. The hydraulic system includes a hydraulic oil pump, which is connected to the superstructure oil pump motor 200. The upper-mount oil pump motor 20 is connected to the chassis 1000 and drives the hydraulic oil pump, enabling multiple working cylinders to perform upper-mount actions. The multi-function controller 30 includes a connected vehicle control module 35 and an oil pump motor control module 32, integrating the vehicle control module 35 and the oil pump motor control module 32. The oil pump motor control module 32 is electrically connected to the upper-mount oil pump motor 20. The multi-function controller 30 controls the upper-mount oil pump motor 20 while simultaneously controlling the new energy special vehicle 1000. By integrating the vehicle control module 35 and the oil pump motor control module 32 with the multi-function controller 30, the upper-mount oil pump motor 20 is directly driven, thereby controlling the working state of the hydraulic oil pump. This eliminates the need for a separate oil pump motor controller on the chassis 10, saving installation space on the chassis 100, simplifying the system structure, and reducing the number of wiring harnesses. This reduces the overall size and weight of the chassis 100 and lowers manufacturing costs.

[0051] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
