Description

Technical Field

[0001] This invention relates to the field of battery storage, and particularly to a battery box. Background Technology

[0002] After production, existing batteries are usually transported together, especially newly developed batteries whose structural strength and performance are not stable enough. After trial production, manufacturers usually transport these batteries to a testing site for testing. Since batteries of different specifications have different sizes and are divided into lithium batteries and pouch batteries with different stability, existing transportation and storage devices can only store one type or similar models of batteries together. When encountering multiple different models of batteries, multiple storage devices are required for separate transportation, which is inefficient.

[0003] Furthermore, during battery transportation, the transport equipment needs to be shockproof, fireproof, waterproof, and heatproof. In other words, it is necessary not only to ensure the battery is protected from external factors during transportation, but also to ensure the battery's own stability.

[0004] With the development of technology, technicians in related fields have also made a lot of optimizations to the battery box to solve some of the above problems. In order to make a more accurate comparison, Chinese patent with publication number CN108910295A discloses a transport box for high-temperature batteries.

[0005] It includes a box body, with slide rails on both sides of the bottom of the box body, and slide grooves on both sides of the box body. A slide rod is slidably connected to the inner cavity of the slide groove, and a buffer spring is welded to the bottom of the slide rod. The bottom of the buffer spring is welded to the bottom of the inner cavity of the slide groove. The inner side of the slide rod passes through the slide groove and is fixedly connected to a placement box. Support seats are fixedly connected to both sides of the bottom of the placement box, and shock-absorbing springs are welded to the outer side of the top of the support seats.

[0006] However, the aforementioned battery box has some shortcomings in actual use:

[0007] 1. Although the battery box can absorb shocks from the placement box using buffer springs and shock absorbers, its transport capacity is affected by the placement box. The transport box is much larger than the placement box, and its shock absorption device occupies a large space. Therefore, the transport capacity of the battery box differs greatly from its overall size, resulting in low transport efficiency.

[0008] 2. The aforementioned battery boxes cannot detect battery temperature in real time, nor do they have a cooling device to cool the batteries. Therefore, during the transportation of high-temperature batteries, if the battery temperature suddenly rises, there is no way to prevent it. Once the battery temperature rises to the maximum limit, it may spontaneously combust or even explode, endangering life safety. Furthermore, multiple of the aforementioned boxes cannot be extended and connected. That is, when multiple battery boxes need to be transported, each box needs to be fixed individually. Therefore, the applicability of the aforementioned battery boxes is not high.

[0009] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing battery boxes. Summary of the Invention

[0015] Preferably, the inner wall of the placement box is also provided with several strip grooves corresponding to the through groove, and a connecting valve is provided at the bottom of the rectangular frame that extends into the rectangular cavity at one end. An air outlet valve that extends through the upper and lower ends of the sealing plate is also provided.

[0016] Preferably, the placement box is provided with a separation component for separating batteries of different specifications and models. The separation component includes several mounting slots opened on the inner wall of the placement box. A horizontal plate is slidably arranged between two horizontally corresponding mounting slots, and a vertical plate is slidably arranged between two vertically corresponding mounting slots. Several insertion slots are opened on the vertical plate, and some insertion slots correspond to the vertical plate.

[0017] Preferably, a sliding groove is provided on the inner wall of one side of the insertion slot, and a sliding plate is slidably arranged in the sliding groove. The lower end of the sliding plate is arc-shaped. A reset push spring is provided between the sliding plate and the sliding groove. The sliding plate on the insertion slot corresponding to the horizontal plate is located in the sliding groove, and the remaining sliding plates are all located outside the sliding groove, thus sealing the insertion slot.

[0018] Preferably, the four inner walls of the rectangular frame are also provided with limiting units for limiting the extension and retraction end of the spring push rod. The limiting unit includes a conical block provided on the outside of the extension and retraction end of the spring push rod.

[0022] I. According to actual transportation needs, the horizontal and vertical plates are installed in the corresponding mounting slots according to the battery size. Different placement areas are formed by the staggered horizontal and vertical plates, which can store batteries of various models in one placement box. After the placement box is placed in the rectangular frame, the sealing plate is covered on the rectangular frame. The vertical stabilizing unit can provide vertical shock protection for the placement box. Similarly, the horizontal stabilizing unit can provide horizontal shock protection for the placement box.

[0023] Second, when the sealing plate is installed on the rectangular frame, the present invention can use the limiting unit to drive the lateral stabilizing unit to limit the placement box. When the placement box needs to be removed, the sealing plate is removed, and the lateral limiting unit will no longer limit the placement box laterally under the drive of the limiting unit. The placement box can be removed from the rectangular frame or reinstalled, saving the installation time of the placement box.

[0024] Third, this invention cools the battery inside the box by using the air cooling heat dissipation of the heat dissipation component, so that the ambient temperature around the battery can be regulated, avoiding the risk of spontaneous combustion or explosion due to excessive temperature. In addition, multiple rectangular frames can be stacked together and expanded by the expansion component. The heat dissipation components can also be connected to each other, and multiple rectangular frames can be supplied with cold air by a single external cold air supply device.

[0036] The following combination Figures 1 to 9 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0037] This application discloses a battery box, which is mainly used in the transportation of multiple batteries of different models. Technically, it prevents damage to the batteries during transportation by providing shockproof treatment to all four sides of the battery box. Especially when transporting batteries with strict temperature requirements, it can dissipate heat through circulating ventilation, and continuously monitor the battery temperature to adjust the cooling intensity. Furthermore, in large-volume transportation, the battery box can be expanded and connected with multiple boxes via an extension mechanism, further improving the applicability of the invention.

[0038] Example 1: Refer to Figure 1 , Figure 2 and Figure 3 As shown, it includes a rectangular frame 1, a placement box 10, a sealing plate 11, and a longitudinal stabilizing unit 2. The placement box 10 is located inside the rectangular frame 1, and both the rectangular frame 1 and the placement box 10 have openings at their upper ends. That is, the placement box 10 can be placed into the rectangular frame 1 through the opening at the upper end of the rectangular frame 1. Similarly, the battery can be placed into the placement box 10 through the opening on the placement box 10.

[0039] A sealing plate 11 is provided at the upper end of the rectangular frame 1 to seal its opening. A temperature sensor (not shown in the figure) is provided on the side of the sealing plate 11 near the placement box 10. After the placement box 10 is filled with batteries and placed inside the rectangular frame 1, the sealing plate 11 can cover the upper end of the rectangular frame 1 to seal and protect the batteries inside the placement box 10. Similarly, during transportation, the temperature of the batteries inside the placement box 10 is monitored in real time by the temperature sensor, so that the staff can intervene in time when the battery temperature is abnormal. The temperature sensor is a known technology, so it will not be described in detail. A longitudinal stabilizing unit 2 is provided at the bottom of the rectangular frame 1 to limit and support the bottom of the placement box 10.

[0040] Continue to refer to Figure 3 As shown, the longitudinal stabilizing unit 2 provides limiting support for the bottom of the placement box 10. Specifically, the longitudinal stabilizing unit 2 includes a push spring rod 20, an upper plate 21, a first rolling ball 22, an elastic rod 23, a top plate 24, and a second rolling ball 25. Several push spring rods 20 are arranged on the inner wall of the rectangular frame 1. The telescopic ends of the push spring rods 20 are all provided with the upper plate 21. That is, when the upper plate 21 is driven by a pushing force, it can drive the telescopic ends of the push spring rods 20 to retract.

[0041] Several rolling balls 22 are rotatably mounted on the upper plate 21 and evenly distributed along its extension. The outer side of the rolling balls 22 contacts and supports the bottom of the placement box 10. When the placement box 10 is placed into the rectangular frame 1, its lower end will contact the outer side of the rolling balls 22. At this time, the push spring rod 20 can indirectly support the placement box 10.

[0042] Several elastic rods 23 are also provided on the lower side of the sealing plate 11. The telescopic ends of the elastic rods 23 are connected to a top plate 24. Several rolling balls 25 are rotatably mounted on the top plate 24. After the sealing plate 11 is placed on the upper end of the rectangular frame 1, the elastic rods 23 can drive the rolling balls 25 to stick tightly to the upper side of the placement box 10. Similarly, when the top plate 24 is driven by an external force, it will also drive the telescopic ends of the elastic rods 23 to retract. During transportation, when vertical vibration or collision occurs, the placement box 10 can indirectly drive the elastic rods 23 and the push spring rod 20 to retract, and the elastic rods 23 and the push spring rod 20 can offset the external force on the placement box 10 in this process.

[0043] When the placement box 10 is subjected to lateral vibration or collision, the placement box 10 can move laterally to reduce friction. At this time, the first ball 22 and the second ball 25 will rotate synchronously.

[0044] Continue to refer to Figure 3 and Figure 4As shown, the four inner walls of the rectangular frame 1 are also provided with lateral stabilizing units 3 for limiting the side of the placement box 10; specifically, the lateral stabilizing unit 3 includes a receiving groove 30, a spring push rod 31, a limiting plate 32 and a ball bearing 33. The four receiving grooves 30 are respectively opened on the four inner walls of the rectangular frame 1. The inner wall of the receiving groove 30 is provided with a spring push rod 31. The extension end of the spring push rod 31 is provided with a limiting plate 32. That is, when the limiting plate 32 is driven by an external force, it can drive the extension end of the spring push rod 31 to retract.

[0045] The upper side of the limiting plate 32 is arc-shaped. Roller balls 33 are rotatably provided on both the arc-shaped surface and the vertical surface of the limiting plate 32. The roller balls 33 are in contact with the outer side of the placement box 10. When the placement box 10 is placed into the rectangular frame 1, the lower end of the placement box 10 will contact the roller balls 33 on the arc-shaped surface and then contact the roller balls 33 on the vertical surface of the limiting plate 32 along the arc-shaped surface, so that the spring push rod 31 can limit the placement box 10 through the roller balls 33.

[0046] Similarly, when the placement box 10 moves up and down to buffer, the ball bearing 33 on the limiting plate 32 can rotate to reduce friction. When the placement box 10 is subjected to lateral vibration, the spring push rod 31 in the corresponding direction can retract to offset the vibration or collision force and prevent the battery from being damaged by vibration.

[0047] Continue to refer to Figure 3 and Figure 5 As shown, a rectangular cavity 40 is also provided inside the rectangular frame 1. A heat dissipation component 4 for air cooling of the battery is provided inside the rectangular cavity 40. Specifically, the heat dissipation component 4 includes a rectangular cavity 40, an annular groove 41, an arc groove 42, a through groove 43, a strip groove 44, a connecting valve 45, and an exhaust valve 46. Several annular grooves 41 are provided at the bottom of the rectangular frame 1 and are connected to the rectangular cavity 40. Gas in the rectangular cavity 40 can be discharged into the rectangular frame 1 through the annular grooves 41. An arc groove 42 corresponding to the annular grooves 41 is provided on the placement box 10. Gas entering the rectangular frame 1 through the annular grooves 41 can enter the placement box 10 to dissipate heat from the battery.

[0048] Several through slots 43 are provided on the four inner walls of the rectangular frame 1, and several strip slots 44 corresponding to the through slots 43 are also provided on the inner wall of the placement box 10. That is, the gas in the rectangular cavity 40 can also enter the rectangular frame 1 through the through slots 43, and the gas can also enter the placement box 10 through the strip slots 44, further dissipating heat from the batteries in the surrounding area of ​​the placement box 10, thereby ensuring that the batteries in the placement box 10 can all come into contact with the heat dissipation gas and dissipate heat together.

[0049] A connecting valve 45 is provided at the bottom of the rectangular frame 1, which extends into the rectangular cavity 40. An air outlet valve 46 is also provided on the sealing plate 11, which is connected to the upper and lower ends of the sealing plate 11.

[0050] That is, an external cold air supply device can be connected to the connecting valve 45. Then, the external cold air supply device supplies cold air into the rectangular cavity 40 through the connecting valve 45. The cold air can then enter the placement box 10 through the arc groove 42 and the strip groove 44 to cool the battery. At this time, the gas in the rectangular frame 1 will be discharged to the outside of the rectangular frame 1 through the exhaust valve 46. The exhaust valve 46 is unidirectional, so the gas in the rectangular frame 1 can only be discharged outwards. External gas will not enter the rectangular frame 1 through the exhaust valve 46. When multiple rectangular frames 1 need to be transported together, the multiple rectangular frames 1 are stacked up. At this time, the exhaust valve 46 on a sealing plate 11 can be inserted into the corresponding connecting valve 45. Then, the external cold air supply device is connected to the connecting valve 45 at the bottom. At this time, multiple rectangular frames 1 can be supplied with cold air. It is not necessary to connect an external cold air supply device to each rectangular frame 1 separately, which improves the applicability of the present invention.

[0051] Reference Figure 6 and Figure 7 As shown, the placement box 10 is equipped with a separator component 5 for separating batteries of different specifications and models. Specifically, the separator component 5 includes a mounting groove 50, a horizontal plate 51, a vertical plate 52, an insertion groove 53, a sliding groove 54, a sliding plate 55, and a reset push spring 56. Several mounting grooves 50 are formed on the inner wall of the placement box 10. A horizontal plate 51 is slidably arranged between two horizontally corresponding mounting grooves 50. The two horizontally corresponding mounting grooves 50 can limit the horizontal plate 51.

[0052] A longitudinal plate 52 is slidably disposed between two longitudinally corresponding mounting slots 50. The two longitudinally corresponding mounting slots 50 can limit the longitudinal plate 52. Several insertion slots 53 are provided on the longitudinal plate 52. Some of the insertion slots 53 correspond to the longitudinal plate 52. The insertion slots 53 are used to make the longitudinal plate 52 and the transverse plate 51 staggered.

[0053] A sliding groove 54 is formed on one inner wall of the insertion slot 53. A sliding plate 55 is slidably disposed in the sliding groove 54. The lower end of the sliding plate 55 is arc-shaped. A return spring 56 is provided between the sliding plate 55 and the sliding groove 54. The sliding plate 55 on the insertion slot 53 corresponding to the horizontal plate 51 is located in the sliding groove 54. The remaining sliding plates 55 are all located outside the sliding groove 54 and block the insertion slot 53. The sliding plate 55 can reciprocate within the sliding groove 54. The return spring 56 drives the corresponding sliding plate in the initial state. 55 is always located outside the sliding groove 54, blocking the insertion groove 53. When the longitudinal plate 52 is inserted into the corresponding mounting groove 50, the sliding plate 55 corresponding to the transverse plate 51 will move into the sliding groove 54 under the drive of the corresponding arc surface. The remaining sliding plate 55 will continue to block the insertion groove 53, so that the area formed by the intersection of the transverse plate 51 and the longitudinal plate 52 is in a sealed state. That is, batteries of different models will not come into contact in different areas, avoiding mutual interference and further improving the safety of battery transportation.

[0054] When the longitudinal plate 52 is removed from the corresponding mounting slot 50 to place the box 10, the sliding plate 55 in the corresponding sliding slot 54 will re-seal the insertion slot 53 under the drive of the reset push spring 56.

[0055] Similarly, depending on actual transportation requirements, the horizontal plate 51 or the vertical plate 52 can be removed and reinstalled according to the battery size, further improving the applicability of the present invention.

[0056] Continue to refer to Figure 1 , Figure 4 and Figure 8 As shown, the four inner walls of the rectangular frame 1 are also provided with limiting units 6 for limiting the extension and retraction ends of the spring push rod 31; specifically, the limiting unit 6 includes a conical block 60, a strip cavity 61, a strip plate 62, a triangular clamping plate 63 and a push spring 64. The conical block 60 is located outside the extension and retraction ends of the spring push rod 31. That is, when the conical block 60 is driven by an external force, it will cause the extension and retraction ends of the corresponding spring push rod 31 to retract, and no longer limit the placement box 10. The rectangular frame 1 has four inner walls with strip-shaped cavities 61, and one side of the strip-shaped cavity 61 is connected to the adjacent receiving groove 30. A strip plate 62 is slidably arranged in the strip-shaped cavity 61. A triangular retaining plate 63 located in the receiving groove 30 is arranged on one side of the strip plate 62, and the triangular retaining plate 63 corresponds to the conical block 60. The strip plate 62 can move up and down in the corresponding strip-shaped cavity 61, and can drive the triangular retaining plate 63 to move synchronously during the movement. When the triangular retaining plate 63 moves upward, it will contact the outer side of the conical block 60.

[0057] A push spring 64 is provided between the inner wall of the strip plate 62 and the strip cavity 61. In the initial state, the push spring 64 indirectly drives the corresponding triangular clamping plate 63 to press against the conical block 60. The pushing force of the push spring 64 is greater than the pushing force of the spring push rod 31. Therefore, the triangular clamping plate 63 can retract the telescopic end of the spring push rod 31 by driving the conical block 60, so that the placement box 10 is no longer subject to lateral limitation.

[0058] The other side of the strip groove 44 is connected to the upper end of the rectangular frame 1, and one side of the strip plate 62 passes through the strip groove 44 and abuts against the sealing plate 11. When the sealing plate 11 is not covering the upper end of the rectangular frame 1, one end of the strip plate 62 is located outside the rectangular frame 1 under the drive of the push spring 64. That is, at this time, the spring push rod 31 does not laterally limit the placement box 10. Therefore, the placement box 10 can be taken out from the rectangular frame 1, and then a new placement box 10 can be placed into the rectangular frame 1 without being blocked by the limiting plate 32. After the placement box 10 is placed, the sealing plate 11 is placed on the upper end of the rectangular frame 1. One end of the strip plate 62 moves downward under the drive of the sealing plate 11. At this time, the triangular plate 63 no longer abuts against the cone block 60, so that the four sides of the placement box 10 will be limited again to achieve the function of shockproof.

[0059] Example 2: Refer to Figure 9 As shown, based on Embodiment 1, in order to stack multiple units of this device during large-scale transportation, an expansion component 7 is provided on the rectangular frame 1 and the sealing plate 11. Specifically, the expansion component 7 includes a rectangular block 70, a bolt 71, an expansion plate 72, and an expansion groove 73. Four rectangular grooves are opened at the upper end of the rectangular frame 1, and four rectangular blocks 70 are respectively inserted into the corresponding rectangular grooves at the lower end of the sealing plate 11. A bolt 71 located in the corresponding rectangular groove is threaded through the outer side of the rectangular frame 1, and the bolt 71 is connected to the corresponding rectangular block 70 in a through connection. When the sealing plate 11 covers the upper end of the rectangular frame 1, the rectangular blocks 70 on the sealing plate 11 will also be installed in the mounting groove 50 at the same time. At this time, the rectangular blocks 70 can be limited and fixed by the bolt 71 to achieve the purpose of fixing the sealing plate 11.

[0060] An expansion plate 72 is also fitted on the outside of the bolt 71. The four outer walls of the rectangular frame 1 are also provided with expansion slots 73 corresponding to the expansion plate 72. That is, another rectangular frame 1 is placed on the sealing plate 11, and then the expansion plate 72 can be inserted into the expansion slot 73 of the other rectangular frame 1 by tightening the bolt 71, thereby limiting the other rectangular frame 1. By repeating this installation, the expansion function of this battery box can be realized.

[0061] During operation: First, according to actual transportation needs, the horizontal plate 51 and the vertical plate 52 are installed in the corresponding mounting slots 50 according to the battery size. Different placement areas are formed by the staggered arrangement of the horizontal plate 51 and the vertical plate 52, which can store various types of batteries in a placement box 10.

[0062] Step 2: Then place the placement box 10 inside the rectangular frame 1 and cover the rectangular frame 1 with the sealing plate 11. At this time, the longitudinal stabilizing unit 2 provides longitudinal shock protection for the placement box 10. Similarly, the transverse stabilizing unit 3 provides transverse shock protection for the placement box 10.

[0063] Step 3: When the sealing plate 11 is installed on the rectangular frame 1, the lateral stabilizing unit 3 can be driven by the limiting unit 6 to limit the placement box 10. When it is necessary to remove the placement box 10, the sealing plate 11 is removed, and the lateral limiting unit 6 will no longer limit the placement box 10 laterally under the drive of the limiting unit 6. The placement box 10 can be removed from the rectangular frame 1 or reinstalled.

[0064] Step 4: The battery inside the housing 10 is cooled by the air cooling of the heat dissipation component 4, so that the ambient temperature around the battery can be regulated to avoid the risk of spontaneous combustion or explosion due to excessive temperature.

[0065] Step 5: By using the expansion component 7, multiple rectangular frames 1 can be stacked together and expanded together. The heat dissipation components 4 can also be connected to each other. A single external cooling supply device can supply cooling to multiple rectangular frames 1.
