Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to an intelligent TBOX integrated system based on dynamic energy management and adaptive heat dissipation. Background Technology

[0002] The four core problems of traditional TBOX are: insufficient heat dissipation efficiency leading to chip lifespan reduction under extreme temperature environments; energy waste and excessive power consumption during sleep due to reliance on vehicle battery power; electromagnetic compatibility and physical interface incompatibility when expanding with external modules; and communication quality fluctuations under complex operating conditions (vibration / rain / snow / signal obstruction).

[0003] Existing TBOX systems generally adopt a passive heat dissipation structure of aluminum heat sink + thermal grease (such as patent CN20221034567.X); the power supply system is mostly directly connected to the vehicle's 12V battery and works through a DC-DC step-down module (such as Bosch's T-Box 3.0 solution); the antenna system mostly uses a fixed-shape FPC antenna with external waterproof rubber ring protection (such as the HUAWEI MH5000 module design).

[0004] Existing technology patent CN20218001234.5 proposes "vehicle-mounted TBOX with cooling fan", which reduces temperature through forced air cooling, but has the following problems: relying on active heat dissipation components (fans) increases power consumption and failure rate; it does not solve the problems of vibration energy recovery and multi-source power supply; and the antenna system does not integrate environmental adaptation function. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes an intelligent TBOX integrated system based on dynamic energy management and adaptive heat dissipation. The specific technical solution is as follows: An intelligent TBOX integrated system based on dynamic energy management and adaptive heat dissipation includes a dynamic energy management module, a fractal flow channel heat dissipation substrate, and a magnetic interface disposed within a TBOX housing. The fractal flow channel heat dissipation substrate is mounted on the dynamic energy management module, and the magnetic interface is disposed on the TBOX housing. The dynamic energy management module includes a vibration energy recovery layer and a power switching circuit. The fractal flow channel heat dissipation substrate adopts a three-level fractal structure with a main channel width of 2mm, a secondary branch width of 1m, and a three-level microchannel. The magnetic interface is equipped with a magnetic positioning structure, which consists of a neodymium iron boron permanent magnet ring and a Hall sensor. The contact is a three-in-one contact, and the power supply, CAN bus, and Ethernet are integrated into the same interface.

[0006] Furthermore, the energy recovery layer consists of a honeycomb PZT array arranged on the inner wall of the outer shell with a spacing of 5mm, and connected to a 10F supercapacitor through a bridge rectifier circuit.

[0007] Furthermore, the power switching circuit uses an LTC4417 chip to achieve seamless switching between three power sources: the main battery, the supercapacitor, and the backup battery.

[0008] Furthermore, the fractal flow channel heat dissipation substrate is made of copper substrate with nickel plating, the nickel plating thickness is 50μm, and the thermal conductivity is ≥380W / m·K.

[0009] Furthermore, the NdFeB permanent magnet ring has a size of Φ8×1mm.

[0010] Furthermore, the built-in antenna of the TBOX integrated system is a liquid metal antenna. The liquid metal antenna has a high-temperature resistant silicone sealed cavity with dimensions of 15×15×2mm. The cavity is filled with 0.5ml of liquid metal and equipped with a 3mm diameter miniature electromagnetic coil. The array controls the liquid metal to form a specific radiator.

[0011] This invention effectively solves the problems in the prior art by setting up a vibration-electric energy collaborative recovery mechanism between the piezoelectric material layer and the supercapacitor, a coupled heat dissipation arrangement of the fractal flow channel and the temperature-controlled flow window, a hardware sandbox isolation of the magnetic interface, and electromagnetic-fluid dynamic control of the liquid metal antenna, thereby realizing dynamic energy management and adaptive heat dissipation of the TBOX.
