Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, and in particular to a super capacitor module and a motor control module. Background Art

[0002] With the increasing popularity of drive-by-wire chassis, EMB (Electronic Mechanical Brake) systems are gaining increasing attention in brake-by-wire racing. Compared to EHB (Electronic Hydraulic Brake) solutions, the EMB system's key advantage is its complete elimination of hydraulic braking, resulting in a simpler structure and faster response. Braking force is generated entirely through the ECU (electronic control unit) driving and controlling the actuator motor, eliminating the need for brake fluid line filling and maintenance. The EMB brake utilizes the ECU to control the servo motor, which in turn directly applies braking force to the wheel cylinders. This replaces the four major components of the EHB brake-by-wire system: ESP (Electronic Stabilty Program), ibooster (Electronic Brake Booster), hydraulic lines, and EPB (Electrical Park Brake), effectively integrating all four mechanical components into one. The supercapacitor in the EMB system is a capacitor with high energy storage, fast charge and discharge speeds, and high current, enabling it to deliver extremely high power in a very short period of time.

[0003] The existing supercapacitor fixing method is vertical installation, which increases the overall height of the motor control module box and is not conducive to chassis layout. In addition, vertical capacitor fixing makes it difficult to apply glue to the capacitor end, and a large amount of glue must be filled in the gap between the capacitor and the shell to ensure load-bearing capacity. The glue can easily block the capacitor's explosion-proof holes, thereby causing danger. Vertical capacitor fixing also uses a retaining bracket / support to fix the capacitor. In order to avoid stress during assembly, a gap must be set between the retaining bracket / support and the capacitor, which sacrifices the strength of the capacitor assembly. Utility Model Content
