Description

Technical Field

[0001] This utility model relates to the field of autonomous driving vehicle chassis technology, specifically a water temperature and level measurable cooling water tank for L4 level autonomous driving vehicle chassis. Background Technology

[0002] Level 4 autonomous driving technology falls under the category of highly automated driving. Level 4 autonomous driving systems can perform all dynamic driving tasks within their designed operating range without driver monitoring or intervention. This level of autonomous driving requires vehicles to possess high-precision environmental perception, path planning, and vehicle control capabilities to achieve safe and efficient autonomous driving. A coolant temperature sensor, installed inside the coolant tank, uses a high-precision temperature detection probe to monitor the coolant temperature in real time. By connecting the sensor to the control system, real-time coolant temperature data can be obtained, and the cooling strategy can be adjusted based on data changes. An alarm and fuse will trip when the coolant temperature is too high to protect the system. A coolant level sensor monitors the coolant level in the tank in real time. When the level is too low, the sensor will issue an alarm signal to remind the driver to add coolant in time to avoid cooling failure due to insufficient coolant. Current automotive chassis cooling water level and water temperature measurement technology suffers from insufficient sensor accuracy and stability. The accuracy and stability of the sensors may be affected by environmental factors, leading to deviations or instability in the measurement data. The maintenance and replacement costs of current automotive chassis cooling water level and water temperature measurement technology are high. The sensors and control systems inside the cooling water tank require regular maintenance and replacement, which increases the vehicle's maintenance costs. Summary of the Invention

There are two fans 202 on the radiator 203, and the two fans 202 are symmetrically arranged about the vertical line of the radiator 203 as the axis of symmetry, which enhances the connection effect between the radiator 203 and the fans 202, allowing the two fans 202 to be used to cool the radiator 203. 3. For heat dissipation, a delivery pipe 204 is fixedly connected to one side of the radiator 203, and a cold water tank 205 is fixedly connected to one end of the delivery pipe 204. The radiator 203 and the cold water tank 205 form a fixed structure through the delivery pipe 204, and the delivery pipe 204 is located between the radiator 203 and the cold water tank 205, which enhances the connection effect between the radiator 203 and the delivery pipe 204. This allows the cooling water in the radiator 203 to be transported to the cold water tank 205 through the delivery pipe 204. A connecting pipe 206 is fixedly connected to one side of the cold water tank 205, connecting... A water pump 207 is fixedly connected to the bottom of pipe 206.

The connecting pipe 206 is located between the cold water tank 205 and the water pump 207, which enhances the connection effect between the cold water tank 205 and the connecting pipe 206. This allows the water pump 207 to transport cooling water into the cold water tank 205 through the connecting pipe 206. Hot water can be transported to the radiator 203 through the hot water pipe 201 via external equipment. The fan 202 can be started simultaneously. The fan 202 can dissipate the heat from the radiator 203, and the cooled water is transported to the cold water tank 205 for storage via the delivery pipe 204. By starting the water pump 207, the water pump 207 can draw water from the cold water tank 205 via the connecting pipe 206 and deliver it via the cooling pipe 208.

Water pump 207 is activated to draw water from the cold water tank 205 via connecting pipe 206 and delivers it through cooling pipe 208. The coolant circulation channel inside the tank 1 ensures that the coolant can evenly and quickly remove heat. Controlling fan speed and adjusting water pump 207 flow rate ensures the smooth operation of the vehicle's cooling system. The water pump 207 can be installed by attaching the mounting plate 301 at the bottom of the water pump 207 to the top of the shock-absorbing pad 302. It can be fixed by tightening the nut 304 to the outer wall of the bolt 303, thereby improving the installation and fixing effect of the water pump 207.
