Description

Technical Field

[0001] This utility model relates to the field of environmental protection, and in particular to an emergency evacuation system for a vehicle fire during environmental testing. Background Technology

[0002] The vehicle environmental testing chamber provides various simulated environmental conditions for vehicle performance testing, such as different temperatures, humidity levels, and wind speeds and volumes. It is easy to control, highly accurate, and can maintain stable conditions even when they change rapidly. It meets the testing environment requirements of vehicles under different operating conditions, enabling various tests such as fuel consumption, emissions, air conditioning cooling and heating performance, defrosting and defogging performance, and low-temperature starting. Vehicle research and development, testing, and other work cannot be separated from the vehicle environmental testing chamber.

[0003] In recent years, the automotive industry's R&D focus has gradually shifted towards environmentally friendly and clean new energy vehicles. Coupled with strong government support and advancements in science and technology, the vigorous development of battery-powered vehicles has become a new direction for the automotive industry. Currently, new energy vehicles use lithium batteries as their power source. Lithium batteries are at risk of failure under extreme conditions, potentially leading to fires. Lithium batteries can undergo chemical combustion, which is extremely difficult to extinguish. To prevent damage to the environmental chamber, it is generally necessary to pull the burning vehicle out of the chamber in an emergency. One existing solution involves using an evacuation vehicle to access the underside of the vehicle, lifting it off the ground, and then using it to evacuate the burning vehicle from the environmental chamber. (See reference...) Figure 1 As shown, this solution has the following drawbacks:

[0004] 1. In order for the evacuation trolley to meet certain load-bearing requirements, the trolley frame must have high strength. Due to the limitation of material strength, the height of the trolley frame cannot be very low.

[0005] 2. To prevent the car from getting stuck in uneven ground, the car needs to have strong passability, and the bottom of the car cannot be too low off the ground.

[0006] 3. The evacuation trolley needs to be placed under the vehicle being tested, and the connection needs to be manually operated. Manual operation in a combustion environment poses a safety hazard.

[0007] Therefore, there is an urgent need for a safe and efficient fire emergency evacuation system. Utility Model Content

[0008] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0009] The technical problem to be solved by this utility model is to provide an emergency evacuation system for vehicle environmental testing that can quickly evacuate the test vehicle from the environmental chamber without manual operation. This utility model is particularly suitable for test vehicles with low chassis (chassis height from the ground is less than 15 cm).

[0010] To solve the above-mentioned technical problems, the present invention provides a vehicle environmental testing emergency evacuation system, comprising:

[0011] The telescopic lifting mechanism 1 is arranged around the vehicle under test, and it raises or lowers the vehicle under test to a specified height according to the telescopic trigger electrical signal.

[0022] Preferably, the vehicle environmental testing emergency evacuation system further improves upon the aforementioned system by including:

[0023] A triggering device, used to generate drive triggering electrical signals and extension triggering electrical signals;

[0024] The environmental chamber door opens upon receiving a drive trigger electrical signal.

[0025] Control device 3, upon receiving a drive trigger electrical signal, controls the carrier mobile vehicle 2 to move under the test vehicle body and then pulls the carrier mobile vehicle 2 out of the environmental chamber.

[0026] The telescopic support component 1.2 extends to the underside of the vehicle body after receiving the telescopic trigger electrical signal;

[0027] The lifting mechanism raises the vehicle to be tested to a specified height after the telescopic carrier 1.2 is in place, and lowers the telescopic carrier 1.2 to the lowest height after the carrier mobile vehicle 2 is in place, so that the vehicle to be tested is placed on the carrier mobile vehicle 2.

[0028] Preferably, in a further improvement of the vehicle environmental testing emergency evacuation system, the triggering device is a fire alarm sensor arranged inside the environmental chamber.

[0029] Alternatively, the triggering device is a trigger button located outside the environmental chamber.

[0030] The working process and technical effects of this utility model are as follows:

[0031] When the vehicle being tested needs to be evacuated in an emergency:

[0032] The telescopic support extends to the bottom of the vehicle under test, the lifting mechanism is activated to lift the telescopic support and raise the vehicle under test.

[0033] The environmental chamber is opened, and the drive unit drives the carrier mobile vehicle into the environmental chamber and under the vehicle being tested.

[0034] The lifting mechanism is activated and lowered, and the telescopic carrier is placed on the carrier mobile vehicle. The drive unit then pulls the carrier mobile vehicle out of the environmental chamber.

[0035] The operation of the above-mentioned devices of this utility model can be controlled by buttons outside the environmental chamber, or it can be achieved by setting the working delay of each device and / or the sequence of triggering electrical signal transmission.

[0036] This invention enables automatic emergency evacuation of the test vehicle triggered by a fire, or manual emergency evacuation of the test vehicle from outside the environmental chamber, without requiring personnel to enter the environmental chamber, thus improving the safety of environmental testing of power batteries.
