Description

Technical Field

[0001] The present invention relates to the technical field of battery transportation, and in particular to a storage and transportation box for new energy batteries. Background Art

[0002] During the transportation of new energy batteries, in order to ensure the safety of the batteries and reduce the damage to the batteries during transportation, the new energy batteries will be placed in a box, and the new energy batteries will be fixed in the box before transportation.

[0003] Existing battery transport boxes mostly use methods of fixing batteries by bundling and strapping, snap fixing, and elastic fixing. The first two fixing methods will directly fix the batteries on the support plate. When the vehicle shakes, the batteries will bump into each other because they cannot buffer the shaking. The third fixing method only uses springs and fixing plates to clamp the batteries. However, when batteries of different sizes (especially heights) are placed on the support plate, this single elastic fixing method cannot adaptively apply effective and uniform fixing force to all batteries. At this time, flexible materials such as sponges need to be stuffed between the batteries and the fixing plate to fill the gap between the batteries and the fixing plate. This process is relatively cumbersome, and the fixing plate cannot apply the same force to all batteries, resulting in different fixing forces on different batteries. During transportation, the batteries will also slide relative to each other, causing collisions between adjacent batteries, thereby causing battery damage. Summary of the Invention

The limiting frame 1 3 and the limiting frame 2 30 are jointly installed with the lower mounting plate 4. The lower mounting plate 4 is provided with a second gas channel 401. The left side of the second gas channel 401 is provided with an air inlet. The lower mounting plate 4 is curved. This shape is used to reduce the probability of the lower mounting plate 4 bending downward. The lower mounting plate 4 is fixed with a mounting frame 6. The mounting frame 6 is provided with evenly distributed mounting grooves. In addition to the mounting grooves on the four sides of the mounting frame 6, the other The remaining mounting slots are all fixedly connected to the limiting airbags 7, which are used to fix the lower side of the battery. The evenly distributed limiting airbags 7 are suitable for batteries of different sizes and in different positions. A gas pipe rack 8 is fixedly connected to the mounting frame 6. The gas pipe rack 8 is composed of a plurality of connecting pipes staggered horizontally and vertically. The gas pipe rack 8 is connected to all the limiting airbags 7, and the gas pipe rack 8 is connected to the second gas channel 401. A gas supply mechanism is provided on the limiting frame 3, and the gas supply mechanism is used to inject gas into the first gas channel 201 and the second gas channel 401. The first gas channel 201 and the second gas channel 401 are both provided with exhaust ports for discharging the gas in all the airbags to facilitate moving the battery out of the box 1. A lower airbag 5 is fixedly connected to the lower side of the lower mounting plate 4, and the lower airbag 5 is connected to the second gas channel 401. The lower airbag 5 has the same function as the upper airbag 202. When multiple lower mounting plates 4 are inserted into the box 1, the lower airbag 5 fixes the upper side of the battery on its lower side.

[0037] like Figures 1-6 As shown, the mounting grooves around the mounting frame 6 are fixed with positioning airbags 9, all of which are connected to the gas pipe rack 8. All of the positioning airbags 9 are divided into four groups, which are respectively located around the mounting frame 6. All of the positioning airbags 9 are used to fix the battery around; the cross-section of the mounting groove on the mounting frame 6 is trapezoidal, and the opening area on the upper side is larger than the opening area on the lower side. The mounting groove is used to limit the lower side of the adjacent positioning airbags 9 and the limiting airbag 7.

[0038] like Figure 3 and Figure 7-11As shown, the air supply mechanism includes a first slide 21, a first sliding cavity 301 is provided in the limit frame 3, the first slide 21 is slidably connected to the first sliding cavity 301, the first slide 21 is composed of a square plate and two upper and lower wedge blocks, a first spring 211 is fixed between the first slide 21 and the limit frame 3, the first spring 211 is used to drive the first slide 21 to reset, the limit frame 3 is slidably connected to the first connecting shell 22 distributed equidistantly, the right side of the first connecting shell 22 is provided with circumferentially distributed through holes, the first connecting shell 22 corresponds to the card slot on the limit frame 3 one by one, the first connecting shell 22 and the first slide The dynamic cavity 301 is connected. A second spring 221 is fixed between the first connecting shell 22 and the first slide 21. The second spring 221 is used to drive the adjacent first connecting shell 22 to reset. The first slide 21 is fixed with equidistantly distributed first baffles 23. The first baffles 23 are used to block the adjacent first connecting shells 22. Initially, the first baffles 23 block the left side of the adjacent first connecting shells 22. A first one-way valve 24 is installed in both the first gas channel 201 and the second gas channel 401. The first one-way valve 24 only allows gas to enter the first gas channel 201 (second gas channel 401). In the first gas channel 201 and the second gas channel 401, a first sealing plate 25 is slidably connected. The first connecting shell 22 is used to squeeze the adjacent first sealing plates 25. The first sealing plates 25 are used to block the air inlet of the first gas channel 201 (the second gas channel 401). Initially, the first sealing plates 25 block the air inlet of the first gas channel 201 (the second gas channel 401). The two first sealing plates 25 are respectively fixed to the upper mounting plate 2 and the lower mounting plate 4 with a third spring 251. The third spring 251 is used to drive the adjacent first sealing plates 25 to reset. The third spring 25 1 has an elastic coefficient greater than that of the second spring 221. The uppermost first connecting shell 22 is used to inject gas into the first gas channel 201, and the remaining first connecting shells 22 are used to inject gas into the second gas channel 401. When the first connecting shell 22 squeezes the adjacent first sealing plate 25, the first sealing plate 25 releases the blockage of the first gas channel 201 (second gas channel 401). At the same time, the through hole of the first connecting shell 22 enters the first gas channel 201 (second gas channel 401), so that the first connecting shell 22 is connected to the first gas channel 201 (second gas channel 401).

[0039] like Figure 3 、 Figure 7-Figure 9 and Figure 15As shown, an air storage chamber 26 is provided on the left side of the box body 1, and high-pressure inert gas is stored in the air storage chamber 26. The air storage chamber 26 is connected to the first sliding chamber 301, and the limit frame 3 is rotatably connected to the regulating tube 27. The regulating tube 27 is provided with a communicating hole. Initially, the axis of the communicating hole is in a vertical state. The axis of the communicating hole of the regulating tube 27 in the figure is in a horizontal state. The regulating tube 27 is located at the connection between the air storage chamber 26 and the first sliding chamber 301. The regulating tube 27 is used to control the communication state of the air storage chamber 26 and the first sliding chamber 301. When the axis of the communicating hole on the regulating tube 27 is aligned with the connection between the air storage chamber 26 and the first sliding chamber 301 (the axis of the communicating hole is horizontal), the inert gas in the air storage chamber 26 can enter the first sliding chamber 301 (as shown in FIG. Figure 8 shown).

[0040] like Figure 7-Figure 9 As shown, the limiting frame 3 is rotatably connected to the first rotating rod 28, and the first rotating rod 28 is threadedly connected to the first extrusion frame 29. The first extrusion frame 29 is composed of a square plate and two wedge blocks distributed above and below. The first extrusion frame 29 is slidably connected to the limiting frame 3. The first extrusion frame 29 is used to squeeze the first slide 21. When the wedge blocks on the first extrusion frame 29 squeeze the wedge blocks on the first slide 21, the first slide 21 slides.

[0041] Working principle:

[0042] When the transport box is needed to transport the battery, first pull the lower mounting plate 4 forward (initially, the position of the lower mounting plate 4 is as shown in the figure). Figure 2 As shown), move the lower mounting plate 4 out of the slots of the limiting frame 1 3 and the limiting frame 2 30, then place the battery on the upper side of the mounting frame 6, and make the battery located between all the positioning airbags 9, and then insert the lower mounting plate 4 into the corresponding slots on the limiting frame 1 3 and the limiting frame 2 30 according to the height of the battery, align the air inlet of the second gas channel 401 on the mounting plate 4 with the corresponding first connecting shell 22, and the first sealing plate 25 on the second gas channel 401 contacts the corresponding first connecting shell 22, and the battery placement operation is completed at this time.

[0043] After the battery is placed in the box 1 , the regulating tube 27 is rotated 90° so that the communicating hole of the regulating tube 27 is aligned with the connecting portion between the gas storage chamber 26 and the first sliding chamber 301 . At this time, the inert gas in the gas storage chamber 26 enters the first sliding chamber 301 . Afterwards, the first rotating rod 28 starts to rotate, and the first rotating rod 28 drives the first extrusion frame 29 to move backward under the action of the thread. When the first extrusion frame 29 contacts the first slide 21, the first extrusion frame 29 continues to move and squeezes the first slide 21. Then the first slide 21 starts to slide to the right in the first sliding cavity 301, and the first slide 21 drives the first baffle 23 thereon to move to the right. The first connecting shell 22 does not move under the blocking action of the first sealing plate 25 (taking the first connecting shell 22 aligned with the second gas channel 401 as an example for description), the second spring 221 starts to compress, the first baffle 23 and the first connecting shell 22 move relative to each other, and the first baffle 23 releases the blockage of the first connecting shell 22. At this time, the inert gas in the first sliding cavity 301 enters the first connecting shell 22.

[0044] After the inert gas enters the first connecting shell 22, the first rotating rod 28 continues to rotate to make the first slide plate 21 continue to move to the right until the second spring 221 is compressed to the limit (at this time, the compressed second spring 22 will not block the flow of the inert gas). The first slide plate 21 drives the first connecting shell 22 to move to the right through the second spring 221. At this time, the first connecting shell 22 squeezes the first sealing plate 25, causing the first sealing plate 25 to move to the right and release the blockage of the second gas channel 401. The third spring 251 is compressed. After that, the inert gas in the first connecting shell 22 enters the second gas channel 401 through the through hole thereon and the first one-way valve 24. The inert gas enters the gas pipe rack 8 through the second gas channel 401. The gas pipe rack 8 transports part of the inert gas to all the limiting airbags 7. The limiting airbags 7 begin to expand and squeeze and fix the lower side of the battery.

[0045] During the process of the inert gas entering the gas tube rack 8 , the gas tube rack 8 delivers another portion of the inert gas to all the positioning air bags 9 , and the positioning air bags 9 begin to expand and fix the peripheral sides of the battery.

[0046] The air intake method of the first gas channel 201 on the mounting plate 2 is consistent with the air intake method of the second gas channel 401 on the above-mentioned mounting plate 4, and is carried out simultaneously. After the inert gas enters the first gas channel 201 through the first connecting shell 22, the inert gas enters the upper air bag 202 through the first gas channel 201, causing the upper air bag 202 to expand and squeeze and fix the upper side of the battery.

[0047] After the battery is fixed, the first rotating rod 28 is stopped and the regulating tube 27 is rotated in the opposite direction to reset the regulating tube 27. Under the action of the first one-way valve 24, the gas in the first gas channel 201 (the second gas channel 401) cannot be discharged. Therefore, the upper airbag 202, the limiting airbag 7 and the locking airbag 9 always remain in an expanded state and maintain the battery fixed state.

[0048] When the battery is moved to the specified position and needs to be taken out, the first rotating rod 28 is rotated in the opposite direction to reset the first extrusion frame 29. At this time, the first slide plate 21 is reset under the action of the first spring 211, and the first connecting shell 22 is reset under the action of the second spring 221. The first baffle 23 blocks the left side of the first connecting shell 22 again. The first sealing plate 25 is reset under the action of the third spring 251. The first sealing plate 25 blocks the first gas channel 201 (second gas channel 401) again, and then the exhaust port of the first gas channel 201 (second gas channel 401) is opened to discharge all the inert gases in the airbag. After that, the lower mounting plate 4 is moved forward and the battery is removed.

[0049] The size of the battery mentioned above is a fixed size and is consistent with the size of the rectangle formed by the inner side surfaces of all the locking airbags 9.

[0050] If the transported batteries have different specifications (different sizes), multiple batteries are placed on the mounting rack 6 at the same time. In this case, the batteries are limited by the upper airbag 202 and the limiting airbag 7 in contact with the batteries. At the same time, the limiting airbag 7 located on the side of the battery fixes the four sides of the battery to reduce the probability of horizontal movement of the battery.

[0051] During battery transportation, if the external temperature is too high or an internal battery fault causes a battery to spontaneously combust or even explode, the pressure and temperature inside the transport box will rise instantly, posing the risk of igniting other batteries.

[0052] Example 2: Based on Example 1, Figure 1-Figure 3 、 Figure 11 、 Figure 12 and Figure 15As shown, a circulation mechanism is also included, which is arranged in the second limiting frame 30 and is used to inject gas into the air storage chamber 26. The circulation mechanism includes an air extraction module 31. The air extraction module 31 consists of a mounting shell and an air extraction pump. The air extraction module 31 is installed on the right side of the box body 1. A second sliding chamber 302 is provided in the second limiting frame 30. The air inlet of the air extraction module 31 is connected to the second sliding chamber 302 through a hose. A pressure valve is installed at the connection between the air inlet of the air extraction module 31 and the second sliding chamber 302. An air outlet valve 33 is installed in the air storage chamber 26. The air outlet valve 33 can only discharge inert gas into the air storage chamber 26. The air outlet valve 33 is connected to the air outlet of the air extraction module 31 through a hose. A sensing module for monitoring the internal temperature is installed in the box body 1. When the temperature exceeds the threshold (battery spontaneous combustion), the air extraction module 31 will automatically open.

[0053] like Figure 12-14As shown, a second slide plate 34 is slidably connected in the second sliding cavity 302. The second slide plate 34 is composed of a square plate and two wedge-shaped blocks distributed up and down. A fourth spring 341 is fixed between the second slide plate 34 and the second limiting frame 30. The fourth spring 341 is used to drive the second slide plate 34 to reset. The second limiting frame 30 is slidably connected to an equidistantly distributed second connecting shell 35. The second connecting shell 35 corresponds to the card slot on the second limiting frame 30 one by one. The second connecting shell 35 is connected to the second sliding cavity 302. The left side of the second connecting shell 35 is provided with circumferentially distributed through holes. The second connecting shell 35 is connected to the second sliding cavity 302. A fifth spring 351 is fixedly connected between the shell 35 and the second slide 34. The fifth spring 351 is used to drive the second connecting shell 35 to reset. The second slide 34 is fixedly connected to second baffles 36 distributed equidistantly. The second baffles 36 are used to block the adjacent second connecting shells 35. Initially, the second baffles 36 seal the right side of the adjacent second connecting shells 35. A second one-way valve 37 is installed in each of the first gas channel 201 and the second gas channel 401. The second one-way valve 37 cannot allow gas to enter the first gas channel 201 (second gas channel 401). In the first gas channel 201 and the second gas channel 401, a second sealing plate 38 is slidably connected. The second sealing plate 38 is used to block the gas outlet of the first gas channel 201 (the second gas channel 401). Initially, the second sealing plate 38 blocks the gas outlet of the first gas channel 201 (the second gas channel 401). A sixth spring 381 is fixedly connected between the two second sealing plates 38 and the upper mounting plate 2 and the lower mounting plate 4, respectively. The sixth spring 381 is used to drive the second sealing plate 38 to reset. The elastic coefficient of the sixth spring 381 is greater than that of the fifth spring 35. 1, the uppermost second connecting shell 35 is used to evacuate the first gas channel 201, and the remaining second connecting shells 35 are used to evacuate the second gas channel 401. The second connecting shell 35 squeezes the adjacent second sealing plate 38, so that the second sealing plate 38 releases the blockage of the first gas channel 201 (second gas channel 401). At the same time, the through hole of the second connecting shell 35 enters the first gas channel 201 (second gas channel 401), so that the second connecting shell 35 is connected to the first gas channel 201 (second gas channel 401).

[0054] like Figure 12 and Figure 13 As shown, the second limiting frame 30 is rotatably connected to the second rotating rod 39, and the second rotating rod 39 is threadedly connected to the second extrusion frame 40. The second extrusion frame 40 is composed of a square plate and two symmetrically distributed wedge blocks. The second extrusion frame 40 is slidably connected to the second limiting frame 30. The second extrusion frame 40 is used to squeeze the second slide 34. When the wedge blocks on the second extrusion frame 40 squeeze the wedge blocks on the second slide 34, the second slide 34 slides.

[0055] Working principle:

[0056] After the lower mounting plate 4 is inserted into the corresponding slots on the limit frame 1 3 and the limit frame 2 30, the air outlet of the second gas channel 401 on the mounting plate 4 is aligned with the corresponding second connecting shell 35, and the second sealing plate 38 on the second gas channel 401 contacts the corresponding second connecting shell 35.

[0057] After the battery is fixed, the second rotating rod 39 starts to rotate. The second rotating rod 39 drives the second extrusion frame 40 to move backward under the action of the thread. As the second extrusion frame 40 moves, the second extrusion frame 40 contacts and squeezes the second slide plate 34. The second slide plate 34 starts to move to the left after being pressed. The second slide plate 34 drives the second baffle 36 thereon to move to the left. At this time, the second connecting shell 35 cannot move under the action of the second sealing plate 38 (taking the second connecting shell 35 aligned with the gas outlet of the second gas channel 401 as an example). The fifth spring 351 starts to compress, and the second baffle 36 moves relative to the second connecting shell 35. The second baffle 36 releases the blockage of the second connecting shell 35. At this time, the gas in the second gas channel 401 enters the second connecting shell 35 through the second one-way valve 37. Subsequently, the inert gas enters the second sliding chamber 302 through the second connecting shell 35. Under the action of the pressure valve, the inert gas will be temporarily stored in the second sliding chamber 302 and cannot be discharged.

[0058] When the battery in the transport box explodes, the sensing module in the box body 1 detects that the temperature has reached the specified value, and the exhaust module 31 starts to work intermittently. The burning battery will burn the corresponding limiting airbag 7, thereby causing the inert gas in the corresponding limiting airbag 7 to be discharged. The discharged high-pressure inert gas dilutes the oxygen content in the box body 1, making the oxygen content lower than the minimum threshold to support combustion, thereby cutting off the oxygen supply for combustion. At the same time, the inert gas absorbs a large amount of heat through rapid volume expansion, which can help reduce the temperature of the combustion area and further suppress the spread of flames.

[0059] During the process of releasing the gas in the burning limit airbag 7, the inert gas in the gas storage chamber 26 will continue to be transported to the second gas channel 401. At this time, the exhaust module 31 starts to perform intermittent exhaust operation. The exhaust module 31 extracts the inert gas in the second sliding chamber 302 through the hose. When the pressure on the pressure valve reaches its own threshold, the inert gas in the second sliding chamber 302 is discharged through the hose. In this process, under the action of the exhaust module 31, the remaining part of the gas in the limiting airbag 7 that has not been burned actively enters the second sliding chamber 302 through the second gas channel 401. At the same time, the exhaust module 31 transports the inert gas to the outlet valve 33 through the hose, and replenishes the inert gas to the gas storage chamber 26 in the form of pulses through the outlet valve 33.

[0060] During the above process, the exhaust module 31 intermittently and actively extracts the inert gas in the remaining airbags and replenishes it to the air storage chamber 26 in a pulsed form, thereby maintaining the pressure in the air storage chamber 26 and ensuring that the inert gas can continue to be released through the rupture of the burned limiting airbag 7 and fill the interior of the box 1, thereby achieving the effect of extinguishing the fire.

[0061] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
