Description

Technical Field

[0001] This utility model relates to a vehicle emergency protection system for self-rescue when the power battery catches fire during the driving of a new energy electric vehicle, and belongs to the technical field of emergency self-rescue systems for new energy electric vehicles. Background Technology

[0002] With the popularization of automobiles and the development of the automotive industry, new energy electric vehicles have rapidly captured the market due to their advantages such as environmental protection and energy saving, low operating costs, high energy efficiency, superior power performance, and high level of intelligence. Electric vehicles have significant advantages in environmental protection, economy, intelligence, and policy support, and are widely recognized by consumers. Moreover, pure electric vehicles do not produce exhaust fumes during operation, effectively reducing emissions of pollutants such as carbon dioxide and nitrogen oxides, which is of great significance for improving urban air quality. With technological advancements and improved infrastructure, their overall competitiveness will continue to increase.

[0003] However, as the number of new energy electric vehicles on the road continues to increase, their safety issues are gradually being exposed. Electric vehicle batteries may experience thermal runaway due to internal short circuits, poor heat dissipation, improper charging, collisions and mechanical damage, driving through water, or aging wiring, leading to battery fires during driving. Once an electric vehicle catches fire, it requires a large amount of cooling water or prolonged cooling to extinguish it completely; traditional firefighting methods are often ineffective or can only delay the spread of the fire. Furthermore, once the battery catches fire and stops supplying power to the vehicle, some vehicles' doors and windows may become inaccessible due to the power outage, and failure to promptly cut off the fire source will threaten the lives and property of the vehicle owner and passengers. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle emergency protection system for self-rescue when the power battery of a new energy electric vehicle catches fire during driving.

[0005] The function of this utility model is achieved in the following ways: This utility model includes a safety warning light, a safety emergency battery, bolts, bolt holes, anti-slip rubber rings, a power battery, a battery front protective shell, springs, a battery towing rope, a rotary motor, and a reinforced heat insulation layer. Its features are: the safety warning light is installed on the side of the safety emergency battery; two bolt holes are provided on the front of the safety emergency battery, with the opening direction of the bolt holes perpendicular to the battery plane; two rotary motors are respectively installed under the vehicle chassis at positions corresponding to the two bolt holes; two bolts are respectively fixed to the drill bits of the two rotary motors and are parallel to the opening direction of the bolt holes; two anti-slip rubber rings are installed on both sides of the power battery; a battery front protective shell is provided at the front of the vehicle chassis; and two springs are installed inside the battery front protective shell. Inside the battery front protective shell, two springs connect one end of the battery towing rope, and the other end of the battery towing rope is connected to the front end of the power battery. The power battery and the safety emergency battery are installed in the same battery shell. A reinforced heat insulation layer is provided between the power battery and the safety emergency battery. Four temperature sensing switches are installed between the vehicle chassis and the power battery. The front end of the power battery is embedded in the battery front protective shell. By compressing the spring, the bolt hole is aligned with the bolt position. Then, by rotating the motor, the bolt is rotated into the bolt hole, so that the entire battery is fixed under the vehicle chassis. This forms a new energy electric vehicle emergency self-rescue system that can both allow the power battery to supply power to the vehicle normally and detach from the vehicle chassis in an emergency to ensure safety. The front end of the power battery is embedded in the front protective shell of the battery. The bolts are screwed into the bolt holes by rotating the rotary motor in the forward direction, thus fixing the battery to the bottom of the car chassis; The anti-slip rubber rings are installed on both sides of the battery, with the installation position lower than the bottom surface of the battery; The battery tow rope has an embedded power line that connects to a safety emergency battery to provide emergency power to the vehicle. The four temperature sensing switches are connected in parallel in the circuit. The advantages of this utility model are: high safety, simple structure, fast emergency response speed. It can provide emergency power to the vehicle while ensuring the safety of the driver and passengers and their property as much as possible, avoiding secondary damage. It has great practical value for emergency self-rescue in the event of a fire in a new energy electric vehicle. Attached Figure Description

[0007] Referring to the accompanying drawings, this utility model includes: a safety warning light 1, a safety emergency battery 2, bolts 3, bolt holes 4, an anti-slip rubber ring 5, a power battery 6, a battery front protective shell 7, a spring 8, a battery towing rope 9, a rotary motor 10, a reinforced heat insulation layer 11, and a temperature sensing switch 12. The safety warning light 1 is installed on the side of the safety emergency battery 2. Two bolt holes 4 are provided on the front of the safety emergency battery 2, and the opening direction of the bolt holes 4 is perpendicular to the plane of the safety emergency battery 2. Two rotary motors 10 are respectively installed under the vehicle chassis at positions corresponding to the two bolt holes 4. Two bolts 3 are respectively fixed to the drill bits of the two rotary motors 10. Parallel to the opening direction of bolt hole 4, two anti-slip rubber rings 5 ​​are installed on both sides of the power battery 6. A battery front protective shell 7 is provided at the front of the vehicle chassis. Two springs 8 are installed inside the battery front protective shell 7. One end of the battery towing rope 9 is connected between the two springs 8 inside the battery front protective shell 7. The other end of the battery towing rope 9 is connected to the front of the power battery 6. The power battery 6 and the emergency safety battery 2 are installed in the same battery shell. A reinforced heat insulation layer 11 is provided between the power battery 6 and the emergency safety battery 2. Four temperature sensing switches 12 are respectively installed between the vehicle chassis and the power battery 6. The front end of the power battery 6 is embedded inside the front protective shell 7. A compression spring 8 aligns the bolt hole 4 with the bolt 3, allowing the rotary motor 10 to rotate the bolt 3 into the bolt hole 4, thus securing the entire battery under the vehicle chassis. This forms a new energy electric vehicle emergency self-rescue system that allows the power battery 6 to supply power to the vehicle normally while also enabling it to detach from the vehicle chassis in an emergency for safety. During driving, if the vehicle's power battery experiences thermal runaway and a sudden temperature rise, the corresponding temperature sensor switch is triggered, activating the circuit, supplying power to the emergency power supply, and illuminating the safety warning light to alert following vehicles. Safety is ensured by the reverse rotation of the motor, which causes the bolt to unscrew from the bolt hole. The entire battery is then separated from the vehicle chassis by the spring. At this point, the car pulls the battery with a battery tow rope to prevent it from falling and causing an accident with other vehicles. The emergency battery continues to supply power to the vehicle through the internal wiring of the battery tow rope to ensure emergency braking and door opening. The anti-slip rubber rings on both sides of the power battery prevent the battery from causing secondary damage to the vehicle due to inertia after emergency braking. This prevents the battery from catching fire and threatening the personal safety and property of the passengers, while providing them with sufficient time to escape and avoid danger.
