Description

Technical Field

[0002] New energy batteries, also known as secondary batteries (rechargeable batteries or rechargeable batteries), refer to batteries that can be repeatedly charged and discharged. Nowadays, new energy batteries are widely used in vehicles driven by new energy sources such as plug-in hybrid drive, pure electric drive and fuel cell drive. New energy batteries will produce flammable and combustion-supporting gases when overheated and overcharged. If the gas cannot be removed in time, it will cause the internal pressure of the battery to increase, and even lead to thermal runaway, which will cause the battery to catch fire and explode, causing safety hazards and losses.

[0018] Beneficial effects of the present invention:

[0019] 1. In order to solve the problem that new energy batteries generate flammable and combustion-supporting gases when overheating and overcharging, which may lead to thermal runaway, fire, and explosion of the battery if they cannot be removed in time, the degassing assembly provided in this application utilizes a snap-fit ​​convex ring, a bellows, and a shaft roller to connect the battery housing with the storage chamber, so that the flammable and combustion-supporting gases enter the storage chamber and are mixed and diluted with the inert gas. The axial flow fan blades provided inside the shaft roller and the gear rings fixedly installed on the outer wall of the shaft roller are engaged with each other through the gears and the gear rings, so that the synchronous rotation of multiple shaft rollers is achieved. Under the action of the axial flow fan blades, the interior of the battery housing can be sucked, so that the flammable and combustion-supporting gases generated by the battery when overheating and overcharging can be removed in time, and the accumulation of gas can be prevented, which may cause battery deformation and thermal runaway, combustion, and explosion.

[0020] 2. To address the issue of battery fire after thermal runaway, the present application employs a piston plate that displaces when the pressure within the storage chamber increases, squeezing the adjacent storage chamber. This allows the inert gas within the adjacent storage chamber to enter the base case, further preventing the battery from thermal runaway. Furthermore, as the inert gas enters the base case, it rotates the corresponding scoop cup fan blades, which in turn drives the screw. The screw, in turn, displaces the two clamping plates, moving the thermal runaway battery pack away from adjacent battery packs, preventing the spread of thermal runaway.

[0021] 3. The provided shedding assembly utilizes the cam that softens at a certain temperature, thereby releasing the clamping connection between the first connecting rod and the second connecting rod. The clamping plate flips downward under the action of the gravity of the battery pack, thereby causing the battery pack to fall off. When the battery pack falls onto the pressure plate, it drives the pressure plate downward, thereby releasing the clamping connection between the bottom plate and the bottom of the bottom box, and then allowing the battery pack that is burning in thermal runaway to detach from the loading box, thereby achieving the processing of a single thermal runaway battery and preventing the thermal runaway from spreading and causing damage to other battery packs.

[0040] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0041] As described in the background technology, new energy batteries will produce flammable and combustion-supporting gases when overheated and overcharged. If the gas cannot be removed in time, the internal pressure of the battery will increase, and even thermal runaway will occur, causing battery fire and explosion, posing a safety hazard and generating losses.

[0042] In order to solve this technical problem, the present invention provides a new energy battery loading box mold, which is applied to the battery loading box.

[0043] Specifically, please refer to Figures 1-12 , the new energy battery loading box mold specifically includes:

[0044] The loading box 1 includes a bottom box 101 at the bottom and a top cover 102 at the top. A plurality of battery housings 103 are installed in an array inside the bottom box 101. Each battery housing 103 is provided with a rolled-up battery cell 104. A plurality of clamping assemblies 3 are installed in an array inside the bottom box 101 and are designed to correspond to the battery housings 103. The interior of the top cover 102 is hollow and a plurality of piston plates 106 are slidably installed in an array. The piston plates 106 form a plurality of storage cavities 105 inside the top cover 102. The storage cavities 105 are designed to correspond to the clamping assemblies 3. A degassing assembly 2 is provided between the storage cavities 105 and the battery housings 103.

[0045] The degassing assembly 2 includes a plurality of snap-fitting protruding rings 201 mounted in an array on the top outer wall of the battery housing 103. The snap-fitting protruding rings 201 are hollow and communicate with the interior of the battery housing 103.

[0046] The ends of the snap-fitting convex ring 201 are all snap-fitted with bellows 202, and a plurality of shaft rollers 203 are rotatably installed in an array on the outer wall of the bottom side of the top cover 102. The interior of the shaft roller 203 is hollow and connected to the interior of the storage chamber 105. A plurality of axial flow fan blades 204 are installed in an array inside the shaft roller 203. The top end of the bellows 202 is rotatably connected to the bottom of the shaft roller 203. The outer walls of the shaft roller 203 are all fixedly installed with gear rings 205, and a gear 208 is rotatably installed between two adjacent gear rings 205.

[0047] The new energy battery loading box mold provided by the present invention is to solve the problem that new energy batteries will generate flammable and combustion-supporting gases when they are overheated and overcharged. If the gas cannot be removed in time, it will cause the internal pressure of the battery to increase, and even cause thermal runaway, thereby causing battery fire and explosion, causing safety hazards and generating losses. The degassing component 2 set in the present application utilizes multiple snap-on convex rings 201 installed in an array on the top of the battery shell 103, and communicates with the interior of the battery shell 103 through the bellows 202 and the shaft roller 203 with the interior of the storage cavity 105 formed inside the top cover 102. When the wrapped battery cell 104 generates flammable and combustion-supporting gases when it is overcharged or overheated, the gas can be transported to the interior of the storage cavity 105. A certain amount of inert gas is stored in the storage cavity 105, thereby diluting the flammable and combustion-supporting gases, preventing the wrapped battery cell 104 from thermal runaway, resulting in battery combustion and explosion. The flammable and combustion-supporting gases generated during overheating and overcharging are in a high-pressure state. When moving into the storage chamber 105, they can drive the axial flow fan blades 204 installed in an array inside the shaft roller 203 to rotate, thereby causing the shaft roller 203 to rotate. Through the gear ring 205 fixedly installed on the outer wall of the shaft roller 203 and the gear 208 meshing between the two gear rings 205, the other shaft rollers 203 can be driven to rotate synchronously. The axial flow fan blades 204 can play a role in sucking the inside of the battery shell 103, preventing the wrapped battery cells 104 from being unable to quickly remove flammable and combustion-supporting gases when they are generated, and accumulating between the battery shell 103 and the wrapped battery cells 104, thereby causing the battery shell 103 to bulge or deform. The synchronous rotation of multiple shaft rollers 203 improves the efficiency of removing flammable and combustion-supporting gases from the battery shell 103, further preventing the battery from thermal runaway and causing combustion and explosion.

[0048] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

A plurality of rollers 203 are rotatably mounted in an array on the outer wall of the bottom side of the top cover 102. The interior of the rollers 203 is hollow and communicates with the interior of the storage chamber 105. A plurality of axial flow blades 204 are mounted in an array inside the rollers 203.

Gears 208 are rotatably mounted between adjacent gear rings 205.

[0054] A sealing disk 206 is slidably mounted inside the multiple snap-fitting protruding rings 201, and a tension spring 207 is fixedly mounted between the bottom of the sealing disk 206 and the inner wall of the snap-fitting protruding ring 201;

[0055] A set of clamping components 3 includes two first air guide grooves 301 symmetrically provided on the outer wall of the top of the bottom box 101. Slide rods 302 are piston-type slidably installed inside the two first air guide grooves 301. A bearing seat 303 is fixedly installed on the outer wall of the slide rod 302 and is located inside the bottom box 101. A screw rod 304 is rotatably installed on the bearing seat 303. A screw block 311 is threadedly mounted on the outer wall of the screw rod 304. A clamping plate 305 is fixedly mounted on the outer wall of the screw block 311.

[0056] A first slide 306 is slidably mounted on the outer wall of the clamping plate 305, and a first connecting rod 308 is hingedly mounted on the first slide 306. A second slide 307 is slidably mounted on the outer wall of the bearing seat 303, and a second connecting rod 309 is hingedly mounted on the second slide 307. A slot is formed at the end of the first connecting rod 308, and a locking protrusion 313 is fixedly mounted on the end of the second connecting rod 309 and can form a locking design with the slot.

[0057] The bottom outer wall of the top cover 102 is symmetrically arrayed with multiple first connecting grooves 312, which are designed to correspond to the multiple first air guide grooves 301. One end of the multiple first connecting grooves 312 is respectively connected to the interior of the multiple storage cavities 105, and the other end of the multiple first connecting grooves 312 is respectively connected to the multiple first air guide grooves 301. A compression spring 310 is fixedly installed between the bottom of the sliding rod 302 and the inner bottom of the first air guide groove 301.

[0058] In order to solve the problem that new energy batteries will generate flammable and combustion-supporting gases when overheating and overcharging, if the gases cannot be discharged in time, the internal pressure of the battery will increase, and even thermal runaway will occur, which will lead to battery fire and explosion, causing safety hazards and losses. The present application uses the degassing component 2 to utilize multiple snap-on protrusions 201 installed in an array on the top of the battery shell 103, and through the bellows 202 and the shaft roller 203, the interior of the battery shell 103 is connected to the storage cavity 105 formed inside the top cover 102. When the wrapped battery cell 104 generates flammable and combustion-supporting gases when overcharged or overheated, the gases can be transported to the storage cavity 105. A certain amount of inert gas is stored in the storage cavity 105, thereby diluting the flammable and combustion-supporting gases, preventing the wrapped battery cell 104 from thermal runaway, resulting in battery combustion and explosion. The flammable and combustion-supporting gases are in a high-pressure state. When they move into the storage chamber 105, they can drive the axial flow fan blades 204 installed in an array inside the shaft roller 203 to rotate, thereby causing the shaft roller 203 to rotate. Through the gear ring 205 fixedly installed on the outer wall of the shaft roller 203 and the gear 208 meshing between the two gear rings 205, the other shaft rollers 203 can be driven to rotate synchronously. The axial flow fan blades 204 can play a role in sucking the inside of the battery shell 103, preventing the wrapped battery cells 104 from being unable to quickly remove flammable and combustion-supporting gases when they are generated, and accumulating between the battery shell 103 and the wrapped battery cells 104, thereby causing the battery shell 103 to bulge or deform. The synchronous rotation of multiple shaft rollers 203 improves the efficiency of removing flammable and combustion-supporting gases from the battery shell 103, and further prevents the battery from thermal runaway, leading to combustion and explosion.

[0059] Specifically, under the action of the sealing disk 206 and the tension spring 207 that are slidably installed inside the snap-fit ​​convex ring 201, the gas between the battery housing 103 and the storage chamber 105 can only move in one direction, which can prevent the inert gas with a certain pressure stored in the storage chamber 105 from entering the battery housing 103 and affecting the wrapped battery core 104. By setting the first air guide groove 301 opened on the top of the bottom box 101 to be connected with the first connecting groove 312 opened at the bottom of the top cover 102, the slide rod 302 slides piston-like inside the first air guide groove 301, and the bearing seat 303 fixedly installed on the outer wall of the slide rod 302 is connected to the clamping plate 305 through the screw block 311 by the screw rod 304 that is rotatably installed on the bearing seat 303, and can rotate, through the first slide 306 and the second slide 307. The first connecting rod 308 and the second connecting rod 309, which are hingedly installed respectively, can be engaged so that the clamping plate 305 can rotate at a certain angle, thereby facilitating the installation of the battery. When the battery is placed on the two clamping plates 305, the clamping plate 305 is rotated by gravity, and the two clamping plates 305 are made parallel by the restriction of the first connecting rod 308 and the second connecting rod 309, so that the battery can be clamped and fixed. The compression spring 310 arranged between the bottom of the sliding rod 302 and the bottom of the first air guide groove 301 and the inert gas of a certain pressure inside the storage chamber 105 can enable the battery housing 103 to play a buffering role through the two clamping plates 305, thereby preventing the new energy vehicle from being shaken during driving, which may cause internal damage to the battery, thereby protecting the battery.

When a problem occurs in a group of batteries, the high-pressure combustion-supporting and flammable gas generated can enter the corresponding storage chamber 105, thereby increasing the internal pressure of the corresponding storage chamber 105, and then driving the piston plate 106 to move to both sides. During the process of the piston plate 106 moving to both sides, it will abut against the corresponding wedge block 505, thereby driving the wedge block 505 to move, thereby releasing the clamping connection between the semi-arc clamping block 504 and the flange 507 provided on the connecting rod 506, and the sealing strip plate 50 The tension spring 503 provided on the other side will drive it to move, so that the corresponding first connecting groove 312 is blocked by the sealing strip plate 501, and the through hole 502 provided on the sealing strip plate 501 will communicate with the corresponding second connecting groove 315. The inert gas enters the second air guide groove 314 from the second connecting groove 315 and then moves into the bottom box 101, so that the inert gas with a certain pressure stored in the storage cavity 105 enters the bottom box 101 to prevent the problematic battery from burning. When the inert gas moves into the bottom box 101, the gas can drive the spoon cup fan blade 316 on one side of the screw rod 304, thereby driving the The movable screw rod 304 rotates, and the screw block 311 is engaged with the thread of the screw rod 304, thereby driving the screw block 311 to move, and then driving the clamping plate 305 to move, so that the battery without problems can be kept away from the battery with problems to prevent the spread of thermal runaway. When the battery has already experienced thermal runaway or combustion, the temperature of the local area will rise due to the thermal runaway of the battery. The first connecting rod 308 and the second connecting rod 309 are connected by the card slot and the card protrusion 313. The card protrusion 313 is made of plastic material and will soften when heated, so that the first connecting rod 308 and the second connecting rod 309 are connected. 09 is released, and the two clamping plates 305 flip downward under the weight of the battery, so that the battery can fall off. When the battery falls off, the battery will press against the pressure plate 402, so that the L-shaped strips 403 fixed on both sides are displaced downward, so that the abutment between the ends of the L-shaped strips 403 and the clamping strips 404 is released, and the clamping strips 404 and the L-shaped strips 403 can be magnetically attracted to each other, so that the bottom plate 401 and the bottom of the bottom box 101 are released, so that the battery with thermal runaway can fall off to the outside of the loading box 1, preventing the thermal runaway from spreading and causing all the batteries inside the loading box 1 to burn and explode.

[0066] The use process of the new energy battery loading box mold provided by the present invention is as follows:

[0067] First, by setting up the degassing assembly 2 and using the snap-fitting convex ring 201, the bellows 202 and the shaft roller 203, the inside of the battery shell 103 is connected to the inside of the top cover 102 to form a storage chamber 105. When the battery is overheated and overcharged to produce flammable and combustion-supporting gases, they can enter the storage chamber 105 and mix with the inert gas stored in the storage chamber 105, thereby diluting them and preventing the flammable and combustion-supporting gases from burning and exploding when the battery is thermally runaway. The entry of flammable and combustion-supporting gases will increase the internal pressure of the corresponding storage chamber 105, thereby causing the piston plate 106 to move to both sides. The piston plate 106 is displaced, squeezing the storage chambers 105 on both sides. During the displacement process of the piston plate 106, it will abut against the wedge block 505 and drive it to move, thereby releasing the clamping connection between the semi-arc block 504 and the flange 507 fixed on the connecting rod 506. Under the action of the second tension spring 503 on the other side of the sealing strip plate 501, it is displaced. The through hole 502 opened through the sealing strip plate 501 and its outer wall is used to block the first connecting groove 312 and connect it to the corresponding second connecting groove 315. The inert gas will enter the second gas guide groove 314 through the second connecting groove 315. When the inert gas moves into the bottom box 101, the corresponding spoon cup fan blade 316 can be rotated, thereby driving the screw rod 304 to rotate, and the screw block 311 is engaged with the thread of the screw rod 304, thereby driving the clamping plate 305 to move the battery away from the battery with the problem. When the battery has thermal runaway and burned, the temperature of the local area rises, thereby softening the clamping protrusion 313, thereby releasing the clamping of the first connecting rod 308 and the second connecting rod 309, and the clamping plate 305 will be released due to the weight of the battery. The battery is flipped over, so that the battery falls off the clamping assembly 3. The falling of the battery will press on the corresponding pressure plate 402, so that the pressure plate 402 moves downward, and the abutment between the L-shaped strips 403 and the snap-on strips 404 on both sides of the pressure plate 402 is released. Through the magnetic attraction between the L-shaped strips 403 and the snap-on strips 404, the snap-on strips 404 are moved into the assembly groove 406, so that the snap-on connection between the bottom plate 401 and the bottom of the bottom box 101 is released, so that the battery that has already experienced thermal runaway combustion can fall off the loading box 1, preventing the thermal runaway from spreading and causing the gas battery to burn and explode.
