Description

Technical Field

[0001] This utility model relates to a control circuit structure for protecting a baby stroller. Background Technology

[0002] With the improvement of modern living standards and the continuous development of technology, intelligent strollers have gradually become popular products in the market. In addition to traditional basic functions such as mobility and stability, these strollers are increasingly integrating high-tech modules, such as intelligent control systems, electric drives, intelligent monitoring, and wireless communication. These intelligent features not only enhance the user experience but also improve the safety and convenience of strollers. However, as stroller functions become increasingly diverse, existing technologies still have some problems and shortcomings in several aspects that urgently need to be addressed.

[0003] Most strollers on the market today have shortcomings in power management, especially in their relatively simple battery management system (BMS) design. Although some strollers are equipped with batteries, the lack of precise battery charge monitoring and temperature detection means users cannot understand the battery's status in real time, leading to safety hazards such as overcharging, over-discharging, and overheating. These problems can shorten battery life and even cause safety accidents such as battery overheating and fire.

[0004] Baby strollers often integrate multiple modules, such as communication modules, display modules, control modules, and electric drive modules, each with different voltage requirements. In current technology, most baby strollers use simple power distribution methods, which may lead to problems such as unstable voltage, insufficient power supply, or overload, causing some modules to malfunction and affecting the overall system's stability and reliability.

[0005] With the application of electric drive technology in strollers, more and more strollers are being equipped with DC motors or brushless motors to propel them forward. However, many existing strollers lack precise motor status monitoring systems, making it impossible to detect motor current, speed, and position information in real time. This introduces instability into motor operation, and any malfunction could severely impact the stroller's motion control, affecting safety.

[0006] Although some high-end strollers now support wireless communication, technical bottlenecks still exist in remote control and monitoring. Wireless communication modules are often limited by signal stability and transmission distance, making it difficult for parents to effectively monitor the stroller's operating status during use, especially in case of malfunction or emergency, making it impossible to take timely and effective measures.

[0007] Most strollers on the market currently offer basic functions such as seat adjustment, but lack convenient user interaction methods and personalized settings options. Parameter settings largely rely on traditional physical buttons, making operation neither intuitive nor intelligent, and failing to meet modern users' demands for smart and personalized features. Furthermore, the lack of voice feedback and diverse audio prompts fails to effectively alert parents to the stroller's operating status or potential problems. Utility Model Content
