Description

Technical Field

[0001] This utility model belongs to the field of automotive power system technology, specifically an external variable frequency power regulation device for automobiles. Background Technology

[0002] During vehicle operation, the performance of the powertrain directly impacts fuel economy and driving experience. Traditional automotive powertrains typically regulate power output through the interaction of the engine and transmission. However, this method relies on mechanical transmission structures, resulting in slow response times and limited adaptability to various operating conditions. While some vehicles utilize electronic control units (ECUs) to optimize engine output, these devices are mostly built-in, complex to install, and difficult to adapt to multiple vehicle models. Furthermore, traditional powertrain regulation devices often require drivers to manually shift gears or adjust throttle input to maintain optimal power output when facing frequently changing road conditions. This not only increases the operational burden but can also lead to inaccurate power distribution, affecting overall vehicle efficiency. Therefore, existing technologies still have room for improvement in enhancing powertrain regulation flexibility and reducing energy consumption. Utility Model Content

[0028] The speed control assembly 3 also includes an elastic support 8, which is fixedly connected to the extension of the connecting sleeve 6. A guide rod 13 is fixedly connected to the end of the elastic support 8 away from the connecting sleeve 6. A buffer spring 14 is slidably connected to the outer surface of the guide rod 13, and both ends of the buffer spring 14 are fixedly connected to the outer surface of the guide rod 13 and the inner wall of the outer casing 19, respectively. This design ensures the device maintains stability during high-speed operation. Furthermore, the speed control assembly 3 also contains several signal transmission cables 18, which are fixedly connected in a circular array inside the frequency converter control unit 4. Each of these cables has a pressure sensor 25 fixedly connected to its end away from the frequency converter control unit 4. The pressure sensors 25 are arranged in a circular array on the outer surface of the outer casing 19. A movable connecting rod 24 is movably connected inside the pressure sensor 25, extending to the outer surface of the pressure sensor 25. A feedback module 26, matching the size of the pressure sensor 25, is fixedly connected to the portion of the movable connecting rod 24 inside the pressure sensor 25. This arrangement enables the device to accurately sense external operating conditions.

[0029] The auxiliary drive mechanism 5 also includes two sliding guide rails 7, respectively located on the top and bottom sides inside the housing 19. Both locating pins 12 extend into the interior of the sliding guide rails 7. A rack guide plate 11 is fixedly connected to the extended portion of the locating pin 12.

[0030] The auxiliary drive mechanism 5 also includes two angle sensors 17, which are fixedly connected to the left end surfaces of the two sliding guide rails 7. A guide rod 13 is fixedly connected to the end of each angle sensor 17 away from the sliding guide rail 7. A heat sink 21 is movably connected to the outer surface of the guide rod 13. A locking bolt 23 is rotatably connected to the left end surface of the heat sink 21, and the locking bolt 23 is rotatably connected to the left inner wall of the outer casing 19. A protective cover plate 20 is fixedly connected to the end of the heat sink 21 away from the inner wall of the outer casing 19. Several heat dissipation fins are fixedly connected to the outer surface of the protective cover plate 20. This design ensures the heat dissipation performance of the device during long-term operation.

[0031] Based on the above structure, the working principle of this utility model is as follows: When the vehicle's driving state changes, the pressure sensor 25 senses the external working condition through the movable linkage 24 and transmits the information to the feedback module 26. The feedback module 26 transmits the data to the frequency converter control unit 4 through the signal transmission cable 18. The frequency converter control unit 4 adjusts the rotation speed of the connecting bushing 6 in real time according to the received data, thereby changing the meshing state of the gear set 10 and driving the rack guide plate 11 to slide along the sliding guide rail 7. The movement of the rack guide plate 11 is limited by the limit block 9 to ensure that it moves within a predetermined range. During this process, the elastic support 8 and the buffer spring 14 work together to absorb the vibration generated during the operation of the device and ensure overall stability.

[0032] The auxiliary drive mechanism 5 functions during low-speed or starting phases of the vehicle. When the vehicle is under heavy load, the adjustment disc 16 receives power input through the connecting bushing 6, driving the gear set 10 to rotate. The gear set 10 achieves precise positioning through the engagement of the locating pin 12 and the sliding guide rail 7. As the rack guide plate 11 moves within the sliding guide rail 7, the buffer spring 14 provides a counterforce to maintain dynamic balance. The angle sensor 17 monitors the rotation angle of the adjustment disc 16 in real time and transmits the data to the heat sink 21 through the guide rod 13, ensuring that the heat dissipation performance meets the requirements.

[0033] The above describes a specific embodiment of this utility model. Through the close cooperation between the various components, the power transmission path is optimized and the power output is flexibly adjusted. This design not only improves the adaptability and reliability of the device but also reduces installation difficulty and adaptation costs, making it suitable for the power adjustment needs of various vehicle models.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0035] During vehicle operation, assuming the vehicle enters an uphill section from a flat road, the external conditions change, and the pressure sensor 25 senses this change through the movable linkage 24. The pressure sensor 25 transmits the sensed signal to the feedback module 26, which processes the signal and transmits the data to the frequency converter control unit 4 via the signal transmission cable 18. The frequency converter control unit 4 calculates the required power output adjustment based on the received data and changes the rotation speed of the connecting bushing 6 in real time. The change in the rotation speed of the connecting bushing 6 causes a corresponding adjustment in the meshing state of the gear set 10, thereby moving the rack guide plate 11 along the sliding guide rail 7. The movement of the rack guide plate 11 is constrained by the limit block 9 to ensure that it slides within a predetermined range. During this process, the elastic support 8 and the buffer spring 14 work together to absorb the vibration generated during the operation of the device, ensuring the stability of the overall structure.

[0036] When the vehicle is at low speed or starting, the auxiliary drive mechanism 5 begins to function. The adjusting disc 16 receives power input from the transmission module 2 via the connecting bushing 6, driving the gear set 10 to rotate. The gear set 10 achieves precise positioning through the engagement of the locating pin 12 and the sliding guide rail 7, ensuring the stability of the power transmission path. As the rack guide plate 11 moves within the sliding guide rail 7, the buffer spring 14 provides a counterforce to maintain dynamic balance, preventing mechanical shocks caused by sudden load changes. Simultaneously, the angle sensor 17 monitors the rotation angle of the adjusting disc 16 in real time and transmits the data to the heat sink 21 via the guide rod 13, ensuring timely heat dissipation during high-load operation and preventing performance degradation due to overheating.

[0037] Under complex road conditions, such as frequent starts and stops or rapid acceleration, the speed control component 3 and the auxiliary drive mechanism 5 work together to adapt to changes in operating conditions. The pressure sensor 25 continuously monitors changes in external operating conditions and transmits the information to the frequency converter control unit 4 via the feedback module 26. The frequency converter control unit 4 adjusts the rotational speed of the connecting bushing 6 based on real-time data, thereby changing the meshing state of the gear set 10 and ultimately achieving precise movement of the rack guide plate 11. The movement range of the rack guide plate 11 is limited by the limit block 9, ensuring the reliability of the device under various operating conditions. Furthermore, the sealing ring 22, through the cooperation of the fixing clamp 15 and the sliding guide rail 7, ensures the internal sealing of the device, preventing dust or moisture from entering and affecting its performance.

[0038] During long-term operation, the heat sink 21, connected to the outer casing 19 by the locking bolts 23, effectively conducts heat to the external environment. The heat dissipation fins on the protective cover 20 further enhance the heat dissipation effect, ensuring that the device can maintain stable operation even in high-temperature environments. At the same time, the circumferential array arrangement of the signal transmission cables 18 allows the pressure sensor 25 to perceive external operating conditions from all directions, thereby improving the device's response speed and accuracy to external changes.

[0039] Through the above steps, this utility model optimizes the power transmission path and flexibly adjusts the power output. The close cooperation between the speed regulating component 3 and the auxiliary drive mechanism 5 not only improves the adaptability and reliability of the device, but also significantly reduces the installation difficulty and adaptation cost, making it suitable for the power adjustment needs of various vehicle models. The above description is only a preferred embodiment of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
