AI Technical Summary
Existing ventilation and heat dissipation solutions for child safety seats suffer from problems such as reduced backrest stiffness, low heat dissipation efficiency of the base, inability of water-cooled heat dissipation devices to adapt to different seasonal needs, high energy consumption, and high failure rate.
The system utilizes a circulating water system to recover the cold and heat energy of the vehicle refrigerator. Through flexible thermal conductive materials and a multi-branch parallel flow channel design in different areas, combined with the vehicle's original pressure sensor and control module, it achieves bidirectional temperature control of the seats, reduces additional power components, and optimizes system energy efficiency by using quick-connect connectors and recyclable materials.
It achieves two-way temperature control for seat heating and cooling, reducing energy consumption and failure rate, improving ride comfort and device versatility, and reducing maintenance costs.

The seat cushion water bag and the backrest water bag are connected by a water pipe through a seat-back adapter to form a complete water flow channel. The water tank is used to store temperature-regulating water. Its outer shell is attached to the heat exchange component of the vehicle refrigerator to recover the cold or heat of the vehicle refrigerator, thereby achieving the cooling or heating of the temperature-regulating water. The water pump is installed in the water flow channel between the water tank and the seat cushion water bag and the backrest water bag through the water inlet pipe. It has forward and reverse operation functions and is used to drive the temperature-regulating water to circulate between the water tank and the seat cushion water bag and the backrest water bag. The water pump is also connected to the vehicle control module to receive start, stop, steering and speed control commands. One end of the vehicle-mounted connection interface is electrically connected to the water pump and temperature sensor, and the other end is electrically connected to the vehicle control module, which is used to realize power transmission and data communication. The water outlet pipe connects the seat cushion water bag, the backrest water bag, and the water tank's return outlet, forming a water circulation loop; The quick-connect water pipe is installed on the seated adapter to connect the water pipe, inlet pipe, and outlet pipe; The vehicle control module reuses the original vehicle seat pressure sensor to determine whether the occupant is seated or not based on the pressure signal detected by the seat pressure sensor. Based on this status and the water temperature signal detected by the temperature sensor, it controls the operation of the water pump and the switching of the working mode of the vehicle refrigerator, thereby realizing the filling, draining and temperature adjustment of the seat cushion water bag and the backrest water bag.
2. The automobile seat temperature adjusting apparatus according to claim 1, characterized by: The seat cushion water bag and backrest water bag are made of flexible thermally conductive material and are fixed to the foamed surface of the seat by adhesive.
