[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-6 As shown, the embodiment of the present invention discloses a self-rescue system for the risk of spontaneous combustion of new energy vehicles, including a battery pack 1, a slide rail 2, a position locking and unlocking mechanism 3 and a fire monitoring and control system 4. The slide rail 2 is installed on the frame. In this embodiment, the slide rail 2 extends to the rear of the frame. When the slide rail 2 is installed, it is high in the front and low in the back, and has a certain slope, which is convenient for the battery pack 1 to be quickly separated from the vehicle body; the battery pack 1 is installed on the slide rail 2 through a plurality of rollers 5. In this embodiment, the plurality of rollers 5 are all installed at the bottom of the battery pack 1, so that the battery pack 1 pushed out of the vehicle body continues to roll backward on the ground away from the vehicle, which effectively ensures the personal safety of the passengers and prevents the vehicle from being burned; the position locking and unlocking mechanism 3 is installed on the frame and corresponds to the position of the battery pack 1; the vehicle body has a passage for the battery pack 1 to enter and exit; the fire monitoring and control system 4 is electrically connected to the position locking and unlocking mechanism 3. When the battery pack 1 is in danger of spontaneous combustion, the position locking and unlocking mechanism 3 and the fire monitoring and control system 4 are used to realize the rapid and automatic separation of the battery pack 1 from the vehicle, thereby improving safety.

[0026] Specifically, the position locking and unlocking mechanism 3 includes a front baffle 31, a spring 32, an electromagnetic telescopic rod 33, a rack 34, a gear 35 and a rear baffle 36. The front baffle 31 is vertically fixed on the frame and is located in front of the battery pack 1; one end of the spring 32 is fixed on the front baffle 31 and is horizontally distributed. In this embodiment, a spring 32 is fixed on both sides of the front baffle 31 to increase the thrust and effectively reduce the impact force on the battery pack 1 when the vehicle collides, thereby reducing the probability of fire caused by the collision; the rear baffle 36 36 is installed on the frame through the rotating shaft 37 and is located at the rear side of the battery pack 1, so that the battery pack 1 is located between the spring 32 and the tailgate 36; the electromagnetic telescopic rod 33 is installed on the frame and is located below the slide rail 2; the fire monitoring and control system 4 is electrically connected to the electromagnetic telescopic rod 33; one end of the rack 34 is fixed on the telescopic rod of the electromagnetic telescopic rod 33 and is distributed horizontally; the gear 35 is installed on the rotating shaft 37 and is meshed with the rack 34 to ensure that the position of the battery pack 1 is locked when it is in a normal state, and unlocked when spontaneous combustion occurs.

[0027] In order to further optimize the technical solution of the present invention, the slide rails 2 are distributed obliquely downward from front to back, which helps the battery pack 1 to quickly detach from the vehicle body.

[0028] Specifically, the fire monitoring and control system 4 includes a smoke alarm 41, a relay 42, a push button switch 43 and a power supply 44. The smoke alarm 41 is installed on the frame and is located above the battery pack 1; the smoke alarm 41, the relay 42 and the push button switch 43 are electrically connected in sequence; the electromagnetic telescopic rod 33 is electrically connected to the push button switch 43; the push button switch 43 is electrically connected to the power supply 44. In this embodiment, the push button switch 43 is a double-button switch. When the old battery pack 1 is removed, the open button of the push button switch 43 is pressed, the electromagnetic telescopic rod 33 pulls the rack 34, the gear 35 rotates, and the tailgate 36 rotates 90 degrees to release the battery pack 1, and the battery pack 1 can slide backward out of the vehicle. When the new battery pack 1 is loaded into the slide rail 2, the close button of the push button switch 43 is pressed, and the electromagnetic telescopic rod 33 pushes the rack 34, drives the gear 35 to rotate, and the tailgate 36 rotates forward 90 degrees to clamp the battery pack 1.

[0029] Working principle of the present invention:

[0030] When the battery pack 1 spontaneously ignites, thick smoke will be generated. The smoke alarm 41 will immediately connect the relay 42 when detecting the smoke, turn on the button switch 43, drive the electromagnetic telescopic rod 33 to pull the rack 34, the gear 35 rotates, and the rear baffle 36 rotates 90 degrees around the rotating shaft 37 to release the battery pack 1. Due to the strong push of the spring 32 at the front end of the battery pack 1 and the inclined distribution of the slide rail 2, the battery pack 1 moves rapidly backward along the slide rail 2 under the action of the roller 5 until it reaches the outside of the vehicle body.

[0031] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0032] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
