The upper and lower housings are connected by a snap-fit ​​structure, which includes a protrusion on the edge of the upper housing and a groove on the edge of the lower housing. The protrusion and groove engage to ensure a tight fit between the two housings. An internal heat insulation layer made of high-temperature resistant material is installed within the protective housing to reduce the impact of the high temperatures in the engine compartment on the main control module. An array of heat dissipation holes is located at the bottom of the protective housing to accelerate heat dissipation from within the housing.

[0006] The signal processing module includes a signal acquisition unit and a signal conversion unit. The input of the signal acquisition unit is connected to the sensor interface via a wire, and the output of the signal acquisition unit is connected to the main control module via the signal conversion unit.

Signal processing module 2 is externally shielded with a metal cover that completely encloses the circuit board of signal processing module 2 to prevent external electromagnetic interference from affecting the signal processing process. The shield is fixed to the outer shell of signal processing module 2 with screws to ensure its stability.

[0024] The output of main control module 1 is connected to the actuator interface via a control cable. The actuator interface is used to connect to vehicle actuator devices, such as fuel injectors or ignition controllers. The control cable is externally wrapped with an insulating protective layer made of flexible material, providing a certain degree of bending resistance. Each end of the control cable is equipped with a quick-connect connector. The quick-connect connector has internal elastic contacts that are crimped into the conductor portion of the control cable, ensuring reliable electrical connection during insertion. The quick-connect connector design simplifies installation and maintenance while improving connection stability.

This shock-absorbing pad design not only improves the installation stability of the main control module 1 but also extends its service life.

[0030] In practical applications, the operating principle of this device is as follows: Signal processing module 2 receives vehicle sensor signals through the sensor interface. The signal acquisition unit transmits the acquired signals to the signal conversion unit, which filters and amplifies the signals before transmitting them to the main control module 1. The main control module 1's internal storage unit stores preset power optimization parameters. The calculation unit dynamically adjusts the power parameters based on real-time vehicle operating data and sends optimized power parameter commands to the actuators via control cables. The display panel 10 displays the vehicle operating status and optimized parameter information in real time. Users can manually adjust the optimized parameters using function buttons 11. The expansion interface 12 supports the connection of external devices, further enhancing the device's functionality and applicability.

[0031] This invention solves the problems of complex installation, unstable signal, and limited functionality of existing external power upgrade devices by working in concert with the main control module 1, signal processing module 2, and related components, thus meeting the diverse needs of users.

[0032] To enable those skilled in the art to fully understand and implement this utility model, the operating principle and implementation steps of this device are explained in detail below with reference to a specific application scenario.

[0033] In practical applications, when a user needs to install an external smart chip power upgrade device on a certain car model, the mounting bracket 3 must first be fixed in a designated position in the vehicle's engine compartment. The mounting bracket 3 is securely connected to the vehicle body via bolts passing through multiple symmetrically distributed mounting holes on its surface. Subsequently, the main control module 1 is connected to the fixing plate on the mounting bracket 3 via an adjusting rod. One end of the adjusting rod is rotatably connected to the fixing plate, and the other end is fixed to the main control module 1 via a lock nut. The adjusting rod has scale markings on its exterior; by adjusting the angle of the adjusting rod, it can precisely adapt to the layout requirements of different vehicle models.

[0034] After mechanical installation is completed, signal processing module 2 receives vehicle sensor signals via sensor interfaces. For example, signals from the intake pressure sensor and throttle position sensor are transmitted to the signal acquisition unit via wires. The signal acquisition unit then transmits the acquired raw signals to the signal conversion unit. The filtering circuit inside the signal conversion unit consists of multiple capacitors and resistors, effectively removing noise interference from the signal. The amplification circuit uses operational amplifiers to enhance signal strength, ensuring the stability of signal transmission. A shielding cover covers the circuit board of signal processing module 2 to prevent external electromagnetic interference from affecting the signal processing process, thereby ensuring signal quality.

[0035] After receiving the processed signal, the main control module 1's internal processing unit dynamically adjusts the power parameters based on the preset power optimization parameters stored in the storage unit and the real-time vehicle operation data. For example, when it detects an increase in throttle opening and a rise in intake pressure, the processing unit calculates a more efficient fuel injection quantity and ignition timing, and sends the optimized command to the actuator via the control cable. The quick-connect connectors at both ends of the control cable ensure reliable electrical connection through flexible contacts, while the insulation layer improves the cable's bending resistance and adapts to complex installation environments.

[0036] During this process, the display panel 10 on the front of the main control module 1 displays the vehicle's operating status and optimization parameter information in real time. The LCD screen uses a backlight assembly to improve the clarity of the displayed content, and a transparent protective film reduces the impact of light reflection on the user's observation. Users can manually adjust some optimization parameters via function buttons 11 to meet personalized needs. In addition, the expansion interface 12 supports connection to external devices such as diagnostic tools or data loggers. The multi-function pins are arranged in a matrix to achieve compatibility with various types of devices, and the sealing gasket of the dust cover 13 effectively prevents dust from entering the interface, ensuring long-term reliability.

[0037] To ensure the safety and stability of the device, the temperature detection unit inside the main control module 1 monitors the operating temperature in real time. When the temperature exceeds a preset threshold, the alarm module triggers a buzzer via the drive circuit to sound an alarm and illuminates an indicator light, reminding the user to perform an inspection or maintenance. The heat insulation layer 9 of the protective housing 4 is made of high-temperature resistant material, reducing the impact of high temperatures in the engine compartment on the main control module 1; the heat dissipation holes 8 accelerate heat dissipation through airflow design, further improving heat dissipation efficiency. The shock-absorbing pad is adhered to the bottom of the main control module 1, absorbing vibrations and impacts during vehicle operation. Its positioning groove matches the bottom contour of the main control module 1 to ensure installation accuracy, while the anti-slip texture increases the friction between the shock-absorbing pad and the mounting surface, enhancing overall stability.

[0038] Through the above steps, this device achieves dynamic optimization of vehicle power output. Signal processing module 2 ensures data accuracy and stability through high-precision signal acquisition and conversion; main control module 1 performs calculations and adjustments based on real-time data, improving vehicle power performance and fuel economy; the design of the protective housing 4, expansion interface 12, and related components further enhances the device's reliability and applicability, meeting diverse user needs. The above embodiments are merely preferred examples. 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.
