AI Technical Summary
Traditional lithium battery box separation equipment takes too long to respond in an emergency and cannot automatically separate in time, causing the fire or dangerous conditions to spread.
An electric start separation actuator is used to replace the bolt connection, and a DC pulse power supply is provided through the lithium battery box BMS, vehicle terminal or fire controller to achieve automatic separation of the lithium battery box body.
After the battery thermal runaway, the lithium battery box is quickly separated to prevent the fire from spreading to the personnel compartment or other equipment in the vehicle, thereby reducing losses.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of emergency separation of lithium battery boxes, in particular to a rapid emergency separation and disposal device for lithium battery boxes. Background Art
[0002] In order to deal with possible dangerous conditions such as thermal runaway, fire, and smoke in lithium batteries, the battery boxes involved should be quickly separated to minimize the harm they cause to the surrounding environment, personnel, and other equipment. To this end, it is necessary to use a lithium battery box rapid emergency separation and disposal device. In specific emergency situations, the device is used to quickly separate the lithium battery box from the relevant equipment or system and properly dispose of it.
[0003] Traditional separation equipment often uses a purely mechanical connection and separation method, relying solely on mechanical locks or bolts to connect the battery box to the surrounding structure. This connection method lacks flexibility and intelligence. In the face of emergencies such as battery thermal runaway, it cannot automatically and promptly receive control signals to initiate the separation process. Instead, manual intervention or a complex and slow mechanical triggering mechanism are required, resulting in a long response time. This often delays the optimal time to respond, allowing the fire or dangerous situation more time to spread.
[0004] To this end, the utility model provides a lithium battery box rapid emergency separation and disposal device. Utility Model Content
[0005] The purpose of the utility model is to provide a lithium battery box rapid emergency separation and disposal device, which is used to work and thus solve the above-mentioned problems.

[0007] Preferably, the bottom end of the non-self-locking electrical connector extends to the interior of the lithium battery box guard plate and is electrically connected to the lithium battery box body.
[0008] Preferably, the electric starter separation actuator consists of an electric starter, an electrical interface lead and a fastening function shell. The bottom of the electric starter separation actuator is provided with a fastening function shell, the top of the electric starter separation actuator is provided with an electric starter, and the top of the electric starter is provided with an electrical interface lead.
[0009] Preferably, the fastening function shell at the bottom of the electric start separation actuator extends into the lithium battery box guard plate and is threadedly connected to the lithium battery box body.
[0010] Preferably, the opening at the bottom of the lithium battery box guard plate can allow the lithium battery box body to be moved out, and the lithium battery box compartment bottom plate is fixed to the outer periphery of the bottom of the lithium battery box guard plate.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0018] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.
[0019] like Figures 1 to 3As shown, a lithium battery box rapid emergency separation and disposal device of the present invention is provided, a lithium battery box guard plate 2 is provided on the top of the lithium battery box compartment bottom plate 1, a lithium battery box main body 3 is provided inside the lithium battery box guard plate 2, non-self-locking electrical connectors 4 are provided at both ends of the top of the lithium battery box guard plate 2, and an electric start separation actuator 5 is provided at the four corners of the top of the lithium battery box guard plate 2. The bottom end of the non-self-locking electrical connector 4 extends to the interior of the lithium battery box guard plate 2 and is electrically connected to the lithium battery box main body 3. The electric start separation actuator 5 consists of an electric starter 501, an electrical interface The lead 502 is composed of a fastening function shell 503. The bottom of the electric start separation actuator 5 is provided with a fastening function shell 503, the top of the electric start separation actuator 5 is provided with an electric starter 501, and the top of the electric starter 501 is provided with an electrical interface lead 502. The fastening function shell 503 at the bottom of the electric start separation actuator 5 extends into the lithium battery box guard plate 2 and is threadedly connected to the lithium battery box body 3. The opening at the bottom of the lithium battery box guard plate 2 can allow the lithium battery box body 3 to be moved out, and the lithium battery box compartment bottom plate 1 is fixed to the outer periphery of the bottom of the lithium battery box guard plate 2.
[0020] Working principle:
[0021] The electrical connector configured for the lithium battery box body 3 is a non-self-locking electrical connector 4, which has the feature of disconnecting the battery box under the action of gravity, and is only connected to the top of the battery compartment with the non-self-locking electrical connector 4 for fastening and installation. The non-self-locking electrical connector 4 can replace the fixing bolts for installing the lithium battery box body 3 and has the function of fastening and installing the lithium battery box body 3. The connection thread specifications and the number of uses of the bottom fastening function housing 503 of the electric start separation actuator 5 are not limited to the description in this text;
[0022] This device is interoperable with the lithium battery compartment's BMS, vehicle terminal, or other fire control system. Once battery thermal runaway is confirmed, the BMS, vehicle terminal, or other fire control system provides a DC pulse starting power source, activating the electrically activated separation actuator 5. This reliably separates the threaded section of the bottom fastening portion of the functional housing 503, effectively separating the lithium battery compartment body 3 from the battery compartment under the action of gravity. This prevents the spread of fire to the passenger compartment or other equipment in the vehicle, minimizing losses.
