Description

Technical Field

[0001] The present invention relates to the technical field of battery pack buffering, and in particular to a battery pack buffering device for a new energy vehicle. Background Art

[0002] Power batteries are one of the important parts of new energy vehicles. They have a significant impact on the driving range, vehicle life and safety of new energy vehicles. Batteries account for nearly 40% of the total cost of new energy vehicles, making them the largest component. Batteries are composed of positive and negative electrode materials, diaphragms and electrolytes. The diaphragms separate the positive and negative electrodes to prevent short circuits. However, due to the tight structure of the battery, the diaphragm will be damaged when the battery vibrates or impacts, causing the battery to short-circuit and burn. Therefore, a buffer device needs to be installed outside the battery to reduce the probability of accidents. The buffer device of the new energy vehicle battery pack in the prior art only protects the battery pack in one direction, and cannot effectively reduce the vibration of the battery pack. At the same time, when the battery pack is seriously heated, it cannot effectively delay the burning time of the battery pack. Summary of the invention

At the same time, the high temperature will melt the outer skin of the carbon-nitrogen mixed block, and the acid in the carbon-nitrogen mixed block will flow out. When the carbon-nitrogen mixed block comes into contact with the acid, it will expand rapidly, filling the space between the bottom box and the battery pack and isolating the heat of the battery pack. At the same time, the carbon-nitrogen mixed block will have a porous structure after expansion, which will not affect the heat absorption of dry ice, thereby delaying the burning time of the battery pack.

[0043] When the battery pack 105 is placed, the side springs 202 are located around the battery pack 105. When the battery pack 105 encounters vibration during operation, it will collide with the left trigger block 212, the rear trigger block 217, the right trigger block 214 and the front trigger block 209. When the left trigger block 212 is pushed, the left spring 213 is squeezed, and the left pressure rod 220 slides outward, thereby pushing the left pressure rod 204 to slide and the front pressure spring 208 is compressed; when the right trigger block 214 is pushed, the right spring 215 is squeezed, and the right rod 219 slides outward, thereby pushing the right pressure rod 207 slides, and the end spring 221 is compressed; when the front trigger block 209 is pushed, the front spring 210 is compressed, and the inner pressure rod 206 slides outward; when the rear trigger block 217 is pushed, the rear spring 218 is compressed, the pull rod 211 slides along the bottom box 101, and the pull rod 211 drives the rotating rod 205 to rotate through the waist hole; when any one of the left pressure rod 204, the rotating rod 205, the inner pressure rod 206 or the right pressure rod 207 contacts the power-off switch 203, the power-off switch 203 controls the interface 106 to disconnect, so as to realize automatic power-off when the battery pack 105 vibrates too much.

[0046] When the temperature of the battery pack 105 rises sharply, the wax block 307 will be melted, and the ejection spring 308 will eject the slider 305. The slider 305 slides along the bottom box 101, and the outer skin of the dry ice pack 301 is cut by the cutter 306, so that the dry ice powder in the dry ice pack 301 is exposed, and quickly absorbs heat, delaying the heating of the battery pack 105. At the same time, the high temperature melts the outer skin of the carbon-nitrogen mixed block 303, and the acid in the carbon-nitrogen mixed block 303 flows out. When the carbon-nitrogen mixed block 303 contacts the acid, the carbon-nitrogen mixed block 303 will expand rapidly, filling the space between the bottom box 101 and the battery pack 105, isolating the heat of the battery pack 105, and at the same time, the carbon-nitrogen mixed block 303 will have a porous structure after expansion, which will not affect the heat absorption of dry ice, thereby delaying the burning time of the battery pack 105.

[0047] The working principle of a new energy vehicle battery pack buffer device disclosed in the present invention is as follows: when in use, the battery pack 105 is placed on the bottom spring 201, the upper cover 102 is closed, the heat conductive sheet 104 is in contact with the battery pack 105, the bottom spring 201 makes the battery pack 105 in close contact with the heat conductive sheet 104, and the sealing ring 108 ensures the sealing effect. When the upper cover 102 is closed, the card 111 enters the card slot 112. The card 111 has a certain elasticity and will be stuck in the card slot 112. At the same time, the push-down block 109 is in contact with the inner push slope block 113. The push-down block 109 moves the inner push slope block 113 and the interface 106 toward the battery pack 105, so that the interface 106 is inserted into the interface of the battery, and the compression spring 114 is compressed. When the battery pack 105 is in use, the heat is conducted to the heat sink 103 through the heat conductive sheet 104 for heat dissipation. When the battery pack 105 is placed, the side springs 202 are located around the battery pack 105. When the battery pack 105 encounters vibration during operation, it will collide with the left trigger block 212, the rear trigger block 217, the right trigger block 214 and the front trigger block 209. When the left trigger block 212 is pushed, the left spring 213 is squeezed, and the left pressure rod 220 slides outward, thereby pushing the left pressure rod 204 to slide and the front pressure spring 208 is compressed; when the right trigger block 214 is pushed, the right spring 215 is squeezed, and the right rod 219 slides outward, thereby pushing the right pressure rod 207 slides, and the end spring 221 is compressed; when the front trigger block 209 is pushed, the front spring 210 is compressed, and the inner pressure rod 206 slides outward; when the rear trigger block 217 is pushed, the rear spring 218 is compressed, the pull rod 211 slides along the bottom box 101, and the pull rod 211 drives the rotating rod 205 to rotate through the waist hole; when any one of the left pressure rod 204, the rotating rod 205, the inner pressure rod 206 or the right pressure rod 207 contacts the power-off switch 203, the power-off switch 203 controls the interface 106 to disconnect, so as to realize automatic power-off when the battery pack 105 vibrates too much. When the temperature of the battery pack 105 rises sharply, the wax block 307 will be melted, and the ejection spring 308 will eject the slider 305. The slider 305 slides along the bottom box 101, and the outer skin of the dry ice pack 301 is cut by the cutter 306, so that the dry ice powder in the dry ice pack 301 is exposed, and quickly absorbs heat, delaying the heating of the battery pack 105. At the same time, the high temperature melts the outer skin of the carbon-nitrogen mixed block 303, and the acid in the carbon-nitrogen mixed block 303 flows out. When the carbon-nitrogen mixed block 303 contacts the acid, the carbon-nitrogen mixed block 303 will expand rapidly, filling the space between the bottom box 101 and the battery pack 105, isolating the heat of the battery pack 105, and at the same time, the carbon-nitrogen mixed block 303 will have a porous structure after expansion, which will not affect the heat absorption of dry ice, thereby delaying the burning time of the battery pack 105.
