Description

Technical Field

[0001] This utility model relates to the field of vehicle power equipment technology, and in particular to a vehicle power integrated device box with heat dissipation. Background Technology

[0002] Currently, most power systems used in transport vehicles on the market adopt a distributed layout, with related power components scattered throughout various parts of the vehicle, connected by long hydraulic lines. This distributed layout has several drawbacks: First, the excessively long hydraulic lines lead to system pressure loss, affecting power transmission efficiency; second, the distributed layout significantly increases the difficulty of equipment maintenance and troubleshooting, requiring inspection of multiple parts of the vehicle, which is time-consuming and labor-intensive; third, most distributed power systems lack reliable cooling systems, and the power components generate a large amount of heat during operation, which cannot be dissipated in time, affecting equipment performance, potentially shortening component lifespan, and even causing safety hazards.

[0003] In view of the shortcomings of the existing technology, there is an urgent need for a device that can realize the integrated arrangement of power components and has a reliable cooling function to solve problems such as pressure loss, inconvenient maintenance and poor heat dissipation. Utility Model Content

[0006] Furthermore, each of the top two sides of one side wall of the integrated housing is provided with an ear hanger, and a rotating pin is rotatably installed inside the ear hanger. The rotating pin is used to fix it to the vehicle body. Two rotating cylinders are provided at the bottom of the corresponding side wall of the integrated housing. One end of the rotating cylinder is hinged to the bottom of the corresponding side wall of the integrated housing, and the other end is used to hinge the vehicle body.

[0007] Furthermore, the mounting base is covered with a protective net below the cooling fan.

[0008] Furthermore, four clamping rings are fixedly installed inside the integrated housing. Two of the clamping rings are used to fix an accumulator. The accumulator is connected to the pipeline between the hydraulic pump and the multi-way valve through a high-pressure hose.

[0009] Furthermore, the top of the hydraulic oil tank is provided with multiple oil return ports, and an oil return filter element is installed inside each oil return port.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figure 1-3 As shown in the illustration, this application discloses a vehicle powertrain integration unit box with heat dissipation, including an integrated box 10. The integrated box 10 is placed in the front-middle section of the vehicle, providing a power source for the entire vehicle. The integrated box 10, as the core load-bearing structure of the powertrain integration system, is welded from high-strength steel and possesses sufficient structural strength to support the weight of each power component. The integrated box 10 houses a diesel tank 20, an engine 30, a hydraulic oil tank 40, an air filter 50, and an air purifier 60. Several multi-way valves 70 are installed on one side wall of the integrated box 10. The diesel tank 20 stores diesel fuel to provide fuel for the engine 30. The engine 30, as the power component of the entire powertrain system, requires a shock-absorbing pad when installed with the integrated box 10. The hydraulic oil tank 40 stores hydraulic oil to provide power to various hydraulic components. The air filter 50 filters the air required for the engine 30 to operate. The air purifier 60 filters the air discharged after the engine 30 has operated. The multi-way valve 70 is used to control the flow direction of hydraulic oil.

[0023] Specifically, engine 30 is a diesel engine that meets the vehicle's power requirements. The fuel inlet of engine 30 is connected to diesel tank 20 via a fuel pipeline to obtain the fuel required for operation. A transfer coupling 31 is connected to the output end of engine 30 via a flange. Two reducers 32 are connected to the two output ends of transfer coupling 31 via flanges, and reducers 32 are used to adjust speed and torque. Hydraulic pumps 33 are connected to the output ends of both reducers 32 via flanges, providing power to the hydraulic system. Two air filters 50 are provided, using high-efficiency air filter elements. The outlets of the two air filters 50 are connected to intake pipes 34 via tee fittings, and then connected to the air intake of engine 30 via intake pipes 34. The air outlet of engine 30 is connected to air filter 60 via exhaust pipes 35. An exhaust pipe 61 is installed at the outlet of air filter 60, extending to the outside of the vehicle to discharge filtered exhaust gas. The engine 30 is connected to a cooling pipe 36, which is made of copper and wrapped with an insulation layer. The two ends of the cooling pipe 36 are connected to the inlet and outlet of the vehicle's coolant tank, respectively, to form a cooling water circulation.

[0024] The inlet of the hydraulic pump 33 is connected to the hydraulic oil tank 40 via a first oil pipe 331, and the outlet is connected to a multi-way valve 70 via a pipeline. The outlet of the multi-way valve 70 is connected to various hydraulic actuators via pipelines. The first oil pipe 331 and other hydraulic connection pipelines are all made of high-pressure rubber hoses, and all connections are sealed with gaskets and secured with clamps to prevent hydraulic oil leakage. The hydraulic oil tank 40 can be welded from steel plates and has internal baffles to reduce hydraulic oil sloshing. Multiple return ports are located on the top of the hydraulic oil tank 40, each containing a return oil filter element 41. The return oil filter element 41 filters impurities in the return oil, ensuring the cleanliness of the hydraulic oil. A second oil pipe is also fixedly installed on the hydraulic oil tank 40, with several oil ports for connecting to various auxiliary hydraulic components.

[0025] Four clamping rings 17 are fixedly installed inside the integrated housing 10. The clamping rings 17 have a two-part structure and are fastened with bolts. Two clamping rings 17 are used to fix an accumulator 80. The accumulator 80 is connected to the pipeline between the hydraulic pump 33 and the multi-way valve 70 through a high-pressure hose to stabilize the hydraulic system pressure.

[0026] Several pressure gauges 18 are installed on the side of the integrated housing 10. The detection ends of the pressure gauges 18 are connected to each hydraulic pipeline, which can display the pressure between the hydraulic pipelines in real time, facilitating real-time monitoring of pipeline pressure and enabling the driver to promptly identify and troubleshoot problems. The pressure gauges 18 are selected with alarm functions. When the pressure exceeds the set range, an alarm signal can be issued to remind the staff to handle the situation in a timely manner.

[0027] A mounting base 11 is located above the engine 30 within the integrated housing 10. The mounting base 11 has several mounting slots, each housing a cooling fan 12. The cooling fan 12 is connected to the vehicle's electronic control system via wires and can automatically start, stop, or adjust its speed based on the temperature within the integrated housing 10. The cooling fan 12 can be an axial flow fan, characterized by its large airflow and high heat dissipation efficiency. It is used to quickly remove the heat generated by the engine 30 and other components, preventing overheating that could affect the performance of components or cause damage, thus extending the equipment's lifespan. A protective net 16, made of stainless steel with a 2-5mm aperture, covers the mounting base 11 below the cooling fan 12. This net ensures ventilation while effectively preventing metal debris from falling into the integrated housing 10 and causing system malfunctions.

[0028] On each side of the top of one side wall of the integrated housing 10, there is an ear hanger 13. The ear hanger 13 has mounting holes machined inside, and a rotating pin 14 is rotatably mounted within the mounting holes via a bearing. The rotating pin 14 is used to fix the integrated housing 10 to the vehicle body, allowing the integrated housing 10 to rotate relative to the vehicle body. Two rotating cylinders 15 are located at the bottom of the corresponding side wall of the integrated housing 10. One end of the rotating cylinder 15 is hinged to the bottom of the corresponding side wall of the integrated housing 10, and the other end is hinged to the vehicle body. When maintenance or repair of the integrated housing 10 is required, the rotation of the integrated housing 10 is driven by the extension and retraction of the rotating cylinders 15, facilitating operation by staff.

[0029] A ladder 19 is fixedly installed on the side of the integrated housing 10. The steps of the ladder 19 are provided with anti-slip texture to facilitate workers to climb to the top for operation.

[0030] The operating principle of the vehicle powertrain integrated device box with heat dissipation in this embodiment is as follows: During operation, the heat generated by the engine 30 and various power components flows upward. When the temperature reaches the set value, the cooling fan 12 starts to expel the hot air outside the integrated box 10. At the same time, the coolant in the cooling pipe 36 circulates to carry away the heat from the engine 30, achieving dual heat dissipation. The operator can monitor the system pressure in real time through the pressure gauge 18. When maintenance is required, the operator controls the extension and retraction of the rotating cylinder 15 to push the integrated box 10 to rotate around the rotating pin 14 to a suitable angle for easy operation.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
