Description

Technical Field

[0001] This invention relates to the field of vehicle power technology, and in particular to a vehicle power module with intelligent adaptation and control modules. Background Technology

[0002] On-board power modules are the core power supply units for new energy vehicles and various on-board electronic devices. They integrate high-power semiconductor switches, gate drivers, passive components, and thermal management components, primarily realizing the conversion, distribution, and control of battery power. They provide stable power to on-board motors, inverters, on-board chargers, and various low-voltage electronic devices, making them a key component ensuring the normal operation of vehicles. With the diversification of on-board electronic devices and the increasing demands for range and performance in new energy vehicles, the practicality, ease of maintenance, and operational stability of on-board power modules are becoming increasingly important. However, current products on the market still have many shortcomings and fail to meet actual usage needs.

[0003] In terms of modular assembly and disassembly, existing vehicle-mounted power modules mostly use glue bonding or multiple bolt fixing methods, lacking standardized and quick assembly and disassembly structures. The connection methods between modules are complex and have poor compatibility. The assembly and disassembly process requires special tools, which is cumbersome, time-consuming and labor-intensive. This not only reduces production assembly efficiency, but also makes it inconvenient to replace modules later. It is easy to damage the module shell or internal components during the assembly and disassembly process, increasing the cost of use and safety hazards.

[0004] In terms of post-maintenance, existing modules are mostly sealed integrated structures with high internal component integration and lack convenient testing and disassembly designs. Troubleshooting requires disassembling the entire module, which is time-consuming and difficult. Moreover, disassembling the sealed structure can easily damage its waterproof and anti-interference performance, leading to secondary failures. At the same time, module failures often require the entire module to be replaced, making it impossible to repair or replace individual faulty components. This results in wasted resources and high maintenance costs. Furthermore, the repair process requires a high level of professional expertise, which is not conducive to grassroots maintenance operations.

[0005] In terms of adaptive control, the control parameters of existing modules are mostly fixed and optimized only for rated operating conditions. They are difficult to adapt to the complex operating conditions during vehicle operation. When the load, input voltage fluctuates or the ambient temperature changes, the output parameters and operating mode cannot be adjusted in real time. This can easily lead to problems such as excessive output ripple, reduced efficiency, and concentrated thermal stress, and may even affect the module's service life and the stability of the vehicle equipment. It is also difficult to adapt to the usage requirements of a wide power range.

[0006] In summary, the shortcomings of existing vehicle-mounted power modules in terms of modular installation and removal, subsequent maintenance, and adaptive control limit their widespread application in the automotive field. Therefore, developing a vehicle-mounted power module that can solve the above-mentioned defects has important practical significance and application value. Summary of the Invention

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The vehicle-mounted power module shown includes a vehicle-mounted power module 1 and an external assembly housing 2. The external assembly housing 2 is composed of several sub-assembly covers 3. The vehicle-mounted power module 1 is installed in the built-in assembly slot 7 inside the sub-assembly covers 3. The sub-assembly covers 3 include a bottom main storage base 4, an electrically controlled external closing cover 5, and an intelligent control component 6. The intelligent control component 6 is integrated and installed inside the bottom main storage base 4 to realize the status monitoring and intelligent control of the vehicle-mounted power module 1.

[0033] The bottom main storage base 4 is a hollow rectangular body with an internal mounting slot 7 that opens at the top. The vehicle-mounted power module 1 is fitted into this internal mounting slot 7. Multiple removable shock-absorbing pads 25 are installed on the inner bottom surface of the internal mounting slot 7, and these removable shock-absorbing pads 25 abut against the bottom of the vehicle-mounted power module 1. The lower surface of the bottom main storage base 4 is also equipped with removable shock-absorbing pads 25, which can effectively absorb vibration and impact during vehicle operation and prevent damage to the internal components of the vehicle-mounted power module 1 due to vibration. The outer side surface of the bottom main storage base 4 has an external lifting slot 8 that opens at the top. The inner side wall of the external lifting slot 8 has a longitudinal guide slot 9 that extends along the vertical length of the external lifting slot 8, providing guidance for the lifting and lowering of the electronically controlled external closing cover 5.

[0034] The electrically controlled external closure cover 5 includes an embedded electric control screw 10, an internal threaded lifting block 11, an external closure cover 12, and an internal support guide tube 13. The embedded electric control screw 10 is vertically installed inside the longitudinal guide groove 9, and its input end is connected to the vehicle-mounted electric control system, which can realize forward and reverse rotation control. The internal threaded lifting block 11 is threadedly engaged with the embedded electric control screw 10 and slides vertically as the embedded electric control screw 10 rotates. The external closure cover 12 is fixed to the outside of the internal threaded lifting block 11 and can rise and fall synchronously with the internal threaded lifting block 11 to realize the opening and closing of the upper opening of the internal assembly groove 7. When the external closure cover 12 is closed, it can form a sealed protection for the vehicle-mounted power module 1. When it is open, it facilitates the disassembly, assembly, and maintenance of the vehicle-mounted power module 1. The built-in support guide tubes 13 are fixed in an array on the inside of the outer closed cover 12. Their positions correspond one-to-one with the built-in guide and storage grooves 19 on the inside of the built-in assembly groove 7. When the outer closed cover 12 is lowered and closed, the built-in support guide tubes 13 are inserted into the inside of the built-in guide and storage grooves 19 to form a closed guide channel.

[0035] The intelligent control component 6 includes an electrically controlled airflow fan 14, a weighing unit 15, a temperature sensing and control module 16, and a metal filter 17. A mounting groove 18 is provided on the lower surface of the bottom-mounted main storage base 4. The electrically controlled airflow fan 14 is fixed inside the mounting groove 18, and its air outlet is connected to the bottom of the built-in airflow storage groove 19. A metal filter 17, made of stainless steel, is installed at the lower opening of the mounting groove 18. It is removable and washable, filtering dust and impurities from the airflow to prevent them from entering the electrically controlled airflow fan 14 and the vehicle-mounted power module 1, causing blockage and damage. The weighing unit 15 is installed on the inner bottom surface of the bottom-mounted main storage base 4 and is in close contact with the bottom of the vehicle-mounted power module 1. It can detect the assembly pressure and assembly status of the vehicle-mounted power module 1 in real time. When an abnormal pressure is detected, an alarm signal is sent to the vehicle's electronic control system to indicate that the module assembly is loose. The temperature sensing and control module 16 is installed inside the built-in support guide tube 13, with its detection end facing the vehicle power module 1. It can collect the operating temperature of the vehicle power module 1 in real time, be electrically connected to the input end of the vehicle electronic control system, and transmit the temperature signal to the electronically controlled guide fan 14 and the vehicle electronic control system to achieve adaptive adjustment of heat dissipation efficiency.

[0036] Multiple built-in airflow receiving slots 19 are provided on the inner side of the built-in mounting slot 7. The bottom of the built-in airflow receiving slot 19 is connected to the air outlet of the electric airflow fan 14, and the top is matched with the built-in support airflow tube 13 to form a directional airflow channel from the bottom of the bottom main storage seat 4 to the inner side of the outer closed cover 12. When the electric airflow fan 14 is working, the external airflow enters the mounting slot 18 after being filtered by the metal filter screen 17, and then enters the built-in support airflow tube 13 through the built-in airflow receiving slot 19. Finally, it is discharged through the side exhaust hole 24 on the outer side of the outer closed cover 12, forming a surrounding heat dissipation for the vehicle power module 1. The side exhaust holes 24 are evenly distributed along the height direction of the outer closed cover 12 to ensure that the heat dissipation airflow is discharged evenly.

[0037] Multiple lifting assembly guide brackets 20 are evenly installed circumferentially on the bottom of the main storage base 4. The horizontality and height of the main storage base 4 can be adjusted by telescopic adjustment to adapt to different vehicle installation spaces. The bottom of the main storage base 4 is equipped with an internal lifting tube 21 and a manual worm gear assembly 22 at the position corresponding to the built-in support guide tube 13. The internal lifting tube 21 is connected to the built-in guide storage groove 19. Its outer wall is provided with a tooth surface 23. The manual worm gear assembly 22 meshes with the tooth surface 23. The operator can drive the internal lifting tube 21 to rise and fall vertically by turning the handwheel of the manual worm gear assembly 22, thereby adjusting the guide direction of the built-in guide storage groove 19. With the speed adjustment of the electrically controlled guide fan 14, the heat dissipation airflow can be precisely controlled.

[0038] Working principle and process of this device:

[0039] Assembly Process: Based on the vehicle installation space, the staff uses the height of the electrically controlled external closed cover 5 of the lifting assembly guide bracket 20 to complete the basic fixation of the sub-assembly cover 3. Then, the vehicle-mounted power module 1 is inserted into the built-in assembly slot 7 of the bottom main storage base 4. Next, a closing cover is installed at the upper opening of the electrically controlled external closed cover 5. At this time, the weighing unit 15 detects the pressure signal of the vehicle-mounted power module 1 and determines the lifting height of the electrically controlled external closed cover 5 based on the pressure signal, such as whether to install one or two vehicle-mounted power modules. After confirming that the power supply module 1 is assembled in place, it sends a signal to the vehicle-mounted electronic control system. The vehicle-mounted electronic control system controls the embedded electronic control screw 10 to rotate, driving the internal thread lifting block 11 to descend along the longitudinal guide groove 9, which in turn drives the external closed cover 12 to descend synchronously until the built-in support guide tube 13 is inserted into the built-in guide and storage groove 19. The external closed cover 12 completes the closure of the built-in assembly groove 7, thus completing the assembly of the vehicle-mounted power supply module 1. Several sub-assembly covers 3 are assembled to form the external assembly housing 2, which can realize the integrated installation of multiple sets of vehicle-mounted power supply modules 1.

[0040] Operation and control process: When the vehicle-mounted power module 1 is working, the temperature sensing and control module 16 collects its operating temperature in real time and transmits it to the electric control fan 14 and the vehicle-mounted electronic control system. When the temperature is within the rated range, the electric control fan 14 runs at a low speed to achieve basic heat dissipation. The airflow enters the mounting slot 18 after being filtered by the metal filter 17, and then enters the built-in support guide tube 13 through the built-in guide and collection slot 19 to perform surround heat dissipation for the vehicle-mounted power module 1. Finally, it is discharged through the side exhaust port 24. When the operating temperature of the vehicle-mounted power module 1 rises due to increased load and voltage fluctuations, exceeding the rated threshold, the temperature sensing and control module 16 triggers the electric control fan. 14. Increase the rotation speed. At the same time, the operator can drive the internal lifting tube 21 to rise and fall through the hand-controlled worm gear assembly 22, thereby adjusting the direction of the flow channel of the built-in flow guide and storage groove 19. When the internal lifting tube 21 rises and falls and inserts into the upper opening of the lower built-in support flow guide tube 13, the assembled built-in flow guide and storage groove 19 is longitudinally connected. In this way, only the bottom electric flow guide fan 14 is needed for heat dissipation. If the temperature continues to rise, the vehicle-mounted electronic control system will adaptively adjust the output parameters of the vehicle-mounted power module 1 according to the signal of the temperature sensing control module 16, increase the power of the electric flow guide fan 14, reduce thermal stress concentration, and ensure its stable operation.

[0041] Maintenance process: When the vehicle-mounted power module 1 needs to be inspected or maintained, the vehicle-mounted electronic control system controls the embedded electronic control screw 10 to rotate in the reverse direction, driving the internal thread lifting block 11 to lift the external closed cover 12, opening the upper opening of the built-in assembly slot 7. The staff can directly remove the vehicle-mounted power module 1 from the built-in assembly slot 7 without special tools, achieving quick disassembly. If the heat dissipation components of the device malfunction, the metal filter screen 17 can be removed separately for cleaning and replacement, or the electronically controlled airflow fan 14 can be removed for repair. If the shock absorption components are damaged, the bolts can be unscrewed to replace the removable shock absorption pad 25. Each component can be disassembled and replaced independently, avoiding the waste of resources caused by replacing the whole system and reducing maintenance costs.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
