Description

Technical Field

[0001] This invention relates to the field of energy storage battery technology, specifically to an energy storage battery mounting structure for use in containers. Background Technology

[0002] Energy storage containers are an integrated and modular energy storage system solution that highly integrates battery systems, energy management systems (EMS), temperature control systems, fire protection systems, and power distribution systems within a standard container. They feature flexible deployment, rapid response, and ease of transportation and maintenance. The battery enclosure is the core component of the energy storage container. It not only provides stable assembly space for individual battery cells and electrical components but also needs to withstand external impacts, vibrations, high temperatures, and humid environments. Its design directly affects system performance and safety.

[0003] A typical battery pack usually consists of a body and a cover, which fit together to form a closed enclosure for housing the battery cells and electrical components. Currently, the connection between the body and the cover is mostly secured with bolts. While this method offers a certain level of strength and reliability, it has some shortcomings in practical applications. During long-term vehicle operation, the continuous vibrations can cause the bolts to loosen, and fatigue cracks can develop at stress concentration points such as the thread roots. As the cracks propagate, the threads gradually fail, reducing the preload of the connection between the body and the cover. This compromises the tightness of the connection, making the battery cells and electrical components more susceptible to contamination from dust and moisture, thus reducing the battery pack's lifespan. Summary of the Invention

[0004] In view of the above problems, this application provides an energy storage battery fixing structure for containers, which effectively improves the overall stability and vibration resistance of the connection between the container cover and the container body after the battery pack is assembled, and ensures the protection of the battery module.

[0005] To achieve the above objectives, the present application provides the following technical solution: The present invention provides a battery fixing structure for a container, including a container body and a cover disposed on the upper part of the container body.

The end of the wedge-shaped push rod away from the axis of the mounting hole abuts against the inner wall of the mounting hole.

[0011] According to an advantageous embodiment, the fastener includes a compression wedge slidably disposed on a U-shaped block. The side of the compression wedge near the axis of the mounting hole extends into the cylinder, and the side of the compression wedge away from the axis of the mounting hole abuts against the inner wall of the mounting hole and one side of the U-shaped block. A return spring three is fixedly disposed on the side of the U-shaped block near the axis of the mounting hole, and the end of the return spring three away from the U-shaped block is connected to the compression wedge.

[0012] According to an advantageous embodiment, the limiting assembly includes a rotating rod disposed inside the cylinder. The top of the rotating rod extends through the interior of the cylinder and is fixedly mounted with a pressure plate. The bottom of the pressure plate is in close contact with the upper part of the U-shaped block. A first protruding ring is fixedly mounted on the middle of the outer side of the rotating rod. One end of the wedge-shaped push rod, near the axis of the mounting hole, extends into the interior of the cylinder and abuts against the outer side of the first protruding ring. The upper and lower ends of the outer side of the rotating rod are both fixedly mounted with second protruding rings that cooperate with the extrusion wedge. The outer side of the second protruding ring abuts against the side of the extrusion wedge located inside the cylinder.

[0013] According to an advantageous embodiment, a U-shaped locking pin is slidably provided on the upper part of the pressure plate, and two symmetrically distributed locking holes are opened on the upper part of the cylinder, with the two vertical sections of the U-shaped locking pin respectively penetrating into the corresponding locking holes.

[0014] According to an advantageous embodiment, the cylinder has symmetrically distributed spring grooves inside, and spring locking pins are fixedly installed in the spring grooves. The outer side of the rotating rod has two annular guide openings that cooperate with the two spring locking pins. The rotating rod has two locking grooves inside that communicate with the annular guide openings. The end of the spring locking pin away from the spring groove extends into the annular guide opening and engages with the locking groove inside the rotating rod.

[0015] According to an advantageous embodiment, a rectangular through-hole plate is provided on the upper part of the flange of the box cover, and the rectangular through-hole plate is connected to the flange of the box cover by a plurality of bolts.

[0016] According to an advantageous embodiment, a storage opening is provided at each of the four bottom corners of the rectangular through-hole plate, the top of the positioning rod contacts the inner wall of the storage opening, and the contact portion between the wedge-shaped positioning block and the flange on the box cover is also located inside the storage opening.

[0017] According to an advantageous embodiment, the bottom of the rectangular through-hole plate is provided with a plurality of storage openings II corresponding to the positions of the cylinders.

[0018] Compared with the prior art, the energy storage battery fixing structure for containers provided in this embodiment of the invention has the following beneficial effects:

[0019] 1. When assembling the cover onto the box body, the present invention adopts a composite connection method with pre-positioning of the positioning component, quick fixing of the snap-fit ​​component, and multiple locking of the limiting component.

[0020] 2. The present invention includes a positioning component, a connecting component, and a locking component. When the lid is assembled onto the box body, the positioning rod and the wedge-shaped positioning block are used to achieve the initial positioning of the lid and the box body, ensuring that the mounting holes on the upper and lower flanges are accurately aligned.

[0021] 3. This invention includes a rectangular through-hole plate, a limiting component, and a spring locking pin. After the box body and the box cover are locked together, rotating the pressure plate can drive the first and second convex rings to rotate. Through the limiting of the first pair of wedge-shaped push rods of the first pair of convex rings, the squeezing of the extrusion wedges by the second pair of convex rings, the locking of the spring locking pin and the locking groove, and the limiting of the pressure plate by the U-shaped locking pin, multiple limiting and locking mechanisms are formed, which enhances the stability of the locking component, further ensures the tight engagement of the U-shaped locking block with the upper and lower flanges, and further improves the tightness of the connection between the box cover and the box body and the vibration resistance.

[0035] The following is in conjunction with the appendix Figure 1 - Figure 12 This application will now be described in further detail.

[0036] Please refer to the following: Figure 1 and Figure 2 A battery mounting structure for a container includes a container body 1 and a cover 2 located on the upper part of the container body 1. A battery module 3 is installed inside the cover 2. Matching flanges 4 are provided on the outer sides of both the container body 1 and the cover 2. Multiple mounting holes 5 are provided on each of the two flanges 4. The ends of the two corresponding mounting holes 5 that are far apart from each other are chamfered. Connecting members 6 for engaging the two flanges 4 are provided in the two corresponding mounting holes 5.

[0037] When assembling the lid 2 onto the body 1, multiple connectors 6 can be used to stably assemble the lid 2 onto the body 1, thereby improving the efficiency of assembling the lid 2 and the body 1.

[0038] See Figure 2 and Figure 7 The upper four corners of the flange 4 on the lid 2 are provided with positioning through holes 7, and the upper four corners of the flange 4 on the body 1 are provided with positioning components 8 that cooperate with the positioning through holes 7 for preliminary positioning of the lid 2.

[0039] See Figure 8 The positioning component 8 includes a positioning rod 81 fixedly mounted on the upper part of the flange 4 on the housing 1. The top end of the positioning rod 81 passes through the positioning through hole 7 and has two grooves symmetrically distributed in front and behind. A reset spring 82 is fixedly mounted in the groove. A wedge-shaped positioning block 83 is fixedly mounted on the end of the reset spring 82 away from the inner wall of the groove. The side of the wedge-shaped positioning block 83 away from the reset spring 82 passes through the groove and contacts the upper part of the flange 4 on the housing cover 2.

[0040] When assembling the lid 2 onto the body 1, the worker first precisely aligns the positioning through hole 7 with the positioning rod 81. Then, the lid 2 is smoothly moved downwards along the axis of the positioning rod 81. During the downward movement of the lid 2, the top of the positioning rod 81 gradually passes through the positioning through hole 7. When the bottom of the lid 2 contacts the wedge-shaped positioning block 83, the flange 4 on the lid 2 applies a downward pressing force to the wedge-shaped positioning block 83, causing the wedge-shaped positioning block 83 to press against the return spring 82 while moving into the groove. At this time, the two symmetrically distributed wedge-shaped positioning blocks... When the positioning blocks 83 approach each other, and the cover 2 is fully fitted with the flange 4 on the box body 1, the squeezing force on the wedge positioning block 83 disappears. The return spring 82 pushes the wedge positioning block 83 to return to its original position, so that it is in close contact with the upper surface of the flange 4 on the cover 2. Through the wedge self-locking structure between the wedge positioning block 83 and the flange 4, the cover 2 can achieve initial positioning during the assembly process, effectively preventing it from shaking in the horizontal direction. At the same time, the mounting holes 5 on the two flanges 4 are precisely aligned, which provides convenience for the subsequent installation of the connecting parts 6.

[0041] See Figure 2 , Figure 3 and Figure 5 The connector 6 includes a cylinder 61 disposed in two corresponding mounting holes 5. Rectangular grooves 62 are provided on both the left and right sides of the cylinder 61. A locking component 63 for engaging the two flanges 4 is disposed in the rectangular groove 62. The locking component 63 includes a U-shaped locking block 631 disposed in the rectangular groove 62. The two horizontal sections on the inner side of the U-shaped locking block 631 are located at the upper part of the flange 4 on the cover 2 and the bottom of the flange 4 on the body 1, respectively.

[0042] See Figure 3 and Figure 5 The engaging assembly 63 also includes a wedge-shaped push rod 632 fixedly mounted on the U-shaped locking block 631, and the wedge-shaped push rod 632 passes through the U-shaped locking block 631. A second reset spring 633 is sleeved on the outer side of the wedge-shaped push rod 632. The two ends of the second reset spring 633 are respectively connected to the inner wall of the rectangular groove 62 and the U-shaped locking block 631. The end of the wedge-shaped push rod 632 away from the axis of the mounting hole 5 abuts against the inner wall of the mounting hole 5.

[0043] After initially positioning the lid 2 on the body 1, the operator can simultaneously press the two wedge-shaped push rods 632 to move the two U-shaped blocks 631 closer together into the rectangular groove 62. During the movement of the U-shaped blocks 631, the return spring 633 will be squeezed until the U-shaped blocks 631 are in contact with the inner wall of the rectangular groove 62. Then, the operator can insert the cylinder 61 into the corresponding two mounting holes 5. After the bottom end of the cylinder 61 is inserted into the corresponding two mounting holes 5, the lower end of the U-shaped blocks 631 will first contact the inner wall of the mounting hole 5. At this time, the cylinder 61 will continue to be pressed down. Due to the guiding action of the inner wall of the mounting hole 5, the U-shaped blocks 631 will continue to remain closed. In the retracted state, when the bottom end of the cylinder 61 is fully inserted into the mounting hole 5, and the lower end of the U-shaped block 631 passes the inner edge of the mounting hole 5 on the lower flange 4, the elastic force of the return spring 633 causes the U-shaped block 631 to pop outward of the rectangular groove 62. At this time, the two horizontal sections on the inner side of the U-shaped block 631 are tightly fitted with the upper surface of the flange 4 on the cover 2 and the lower surface of the flange 4 on the body 2, forming a horizontal locking constraint. At the same time, one end of the wedge-shaped push rod 632 is pressed against the inner wall of the mounting hole 5 to ensure the stability of the cylinder 61 after it is placed in the two mounting holes 5. Through the fixing effect of the U-shaped block 631 on the upper and lower flanges 4, the cover 2 and the body 1 are locked together.

[0044] See Figure 3 , Figure 4 and Figure 5 The U-shaped locking block 631 is provided with a fixing member 64 that cooperates with it to lock the box body 1 and the box cover 2. The fixing member 64 includes a pressing wedge 641 that is slidably disposed on the U-shaped locking block 631. The side of the pressing wedge 641 near the axis of the mounting hole 5 penetrates into the cylinder 61, and the side of the pressing wedge 641 away from the axis of the mounting hole 5 abuts against the wall of the mounting hole 5 and one side of the U-shaped locking block 631. A return spring 642 is fixedly disposed on the side of the U-shaped locking block 631 near the axis of the mounting hole 5. The end of the return spring 642 away from the U-shaped locking block 631 is connected to the pressing wedge 641.

[0045] See Figure 3 , Figure 4 , Figure 5 and Figure 11The cylinder 61 is also provided with a limiting component 65 for limiting the engagement assembly 63 and the fixing member 64. The limiting component 65 includes a rotating rod 651 disposed inside the cylinder 61. The top of the rotating rod 651 extends through the interior of the cylinder 61 and is fixedly mounted with a pressure plate 652. The bottom of the pressure plate 652 is in close contact with the upper part of the U-shaped locking block 631. A first protruding ring 653 is fixedly mounted on the middle of the outer side of the rotating rod 651. One end of the wedge-shaped push rod 632, near the axis of the mounting hole 5, extends into the interior of the cylinder 61 and abuts against the outer side of the first protruding ring 653. The upper and lower ends of the outer side of the rotating rod 651 are both fixedly mounted with a second protruding ring 654 for use with the extrusion wedge 641, and the outer side of the second protruding ring 654 abuts against the side of the extrusion wedge 641 located inside the cylinder 61.

[0046] See Figure 5 , Figure 6 and Figure 10 The cylinder 61 has symmetrically distributed spring grooves inside, and spring locking pins 11 are fixedly installed in the spring grooves. The outer side of the rotating rod 651 has two annular guide ports 12 that cooperate with the two spring locking pins 11. The rotating rod 651 has two locking grooves 13 that communicate with the annular guide ports 12 inside. The end of the spring locking pin 11 away from the spring groove extends into the annular guide port 12 and engages with the locking groove 13 inside the rotating rod 651.

[0047] See Figure 5 , Figure 6 and Figure 12 The upper part of the pressure plate 652 is provided with a U-shaped locking pin 9, and the upper part of the cylinder 61 has two symmetrically distributed locking holes 10, and the two vertical sections of the U-shaped locking pin 9 are respectively inserted into the corresponding locking holes 10.

[0048] After accurately inserting the cylinder 61 into the corresponding two mounting holes 5, the operator manually rotates the pressure plate 652, causing the rotating rod 651 to rotate synchronously inside the cylinder 61. During the rotation of the rotating rod 651, the convex ring 653 on its outer middle contacts one end of the wedge-shaped push rod 632 that extends into the cylinder 61, and applies a squeezing force to the wedge-shaped push rod 632, causing it to move outward until the end away from the convex ring 653 is tightly abutted against the inner wall of the mounting hole 5, restricting its left and right movement and preventing the U-shaped locking block 631 from being damaged by external force. The action retracts, maintaining the initial clamping state of the locking assembly 63. At the same time, the two protruding rings 654 at the upper and lower ends of the outer side of the rotating rod 651 rotate synchronously, squeezing the pressing wedge 641. Under the push of the two protruding rings 654, the pressing wedge 641 overcomes the elastic force of the return spring 642, so that the side of the pressing wedge 641 away from the two protruding rings 654 abuts against the inner wall of the mounting hole 5 and the side of the U-shaped locking block 631, further ensuring the locking effect of the U-shaped locking block 631 on the cover 2 and the box body 1, and avoiding vibration causing the locking to loosen.

[0049] During the rotation of the rotating rod 651, the spring locking pin 11 always slides along the annular guide opening 12 on the outer side of the rotating rod 651, providing stable guidance and limiting for the rotating rod 651 and preventing radial deviation during rotation. When the pressure plate 652 rotates until the opening through which the U-shaped locking pin 9 passes aligns with the locking hole 10 on the cylinder 61, the rotation operation stops. At this time, the U-shaped locking pin 9 is inserted into the corresponding locking hole 10, with its two vertical sections penetrating the pressure plate 652 and the cylinder 61 respectively, effectively preventing accidental rotation of the pressure plate 652 and the rotating rod 651. At the same time, the spring locking pin 11 springs into the locking groove 13 inside the rotating rod 651 under its own elasticity, realizing axial locking of the rotating rod 651, further ensuring that the position of the rotating rod 651 is fixed and preventing it from rotating in a vibration environment.

[0050] The limiting of the wedge-shaped push rod 632 by the first convex ring 653, the pressing of the extrusion wedge 641 by the second convex ring 654, the locking of the spring locking pin 11 and the locking groove 13, and the limiting of the pressure plate 652 by the U-shaped locking pin 9 form a multi-limiting locking, which enhances the stability of the engaging assembly 63, further ensures the tight engagement of the U-shaped locking block 631 with the upper and lower flanges 4, effectively improves the overall stability and vibration resistance of the connection between the cover 2 and the body 1, and ensures the protection of the battery module 3.

[0051] See Figure 1 and Figure 2 A rectangular through-hole plate 14 is provided on the upper part of the flange 4 on the box cover 2, and the rectangular through-hole plate 14 is connected to the flange 4 on the box cover 2 by multiple bolts 15.

[0052] See Figure 3 and Figure 9 The rectangular through-hole plate 14 has storage openings 16 at the four corners of its bottom. The top of the positioning rod 81 contacts the inner wall of the storage opening 16, and the wedge-shaped positioning block 83 is also located inside the storage opening 16 in contact with the flange 4 on the box cover 2.

[0053] See Figure 3 and Figure 9 The bottom of the rectangular through-hole plate 14 has multiple storage openings 17 corresponding to the positions of the cylinder 61. The outer horizontal section of the U-shaped latch 9 is in close contact with the inner wall of the storage opening 17, and the contact part between the U-shaped latch 631 and the flange 4 on the lid 2 is also located inside the storage opening 17.

[0054] After the U-shaped locking block 631 engages the cover 2 and the body 1, the operator can place the rectangular through-hole plate 14 on the upper part of the flange 4 on the cover 2. At this time, the inner wall of the first storage opening 16 contacts the top of the positioning rod 81, and the inner wall of the second storage opening 17 contacts the outer horizontal section of the U-shaped locking pin 9, which can limit the U-shaped locking pin 9, thereby indirectly ensuring the engagement stability of the U-shaped locking block 631 with the cover 2 and the body 1. Then, the rectangular through-hole plate 14 can be installed on the flange 4 on the cover 2 by bolts 15. This not only enhances the overall strength of the connection structure between the cover 2 and the body 1, but also forms a secondary protection for the engaging component 63 and the positioning component 8, effectively preventing dust, moisture and other external impurities from entering the battery pack, further improving the sealing and protection performance of the battery pack.

[0055] When the battery module 3 needs to be repaired, the rectangular through plate 14 can be removed first, and then the U-shaped locking pin 9 can be removed from the pressure plate 652. Next, the pressure plate 652 is rotated to drive the rotating rod 651 to rotate, so that the spring locking pin moves out of the locking groove 13. At the same time, the first convex ring 653 and the second convex ring 654 rotate to release the compression of the wedge-shaped push rod 632 and the extrusion wedge plate respectively. Then, the two corresponding U-shaped locking blocks 631 can be pressed to bring them closer to each other. Finally, the cylinder 61 can be removed from the two corresponding mounting holes 5, and then the cover 2 can be separated from the box body 1 to repair the battery module 3.

[0056] In practice, the positioning component 8 is used to initially position the lid 2 and the body 1, effectively preventing the lid 2 from shaking in the horizontal direction and ensuring that the mounting holes 5 on the upper and lower flanges 4 are precisely aligned. Then, the operator can insert the cylinder 61 into the corresponding two mounting holes 5. At this time, the two flanges 4 can be fixed by the U-shaped locking block 631, so that the lid 2 and the body 1 can be quickly locked together.

[0057] Then, the operator rotates the pressure plate 652, which drives the rotating rod 651 to rotate. The rotation of the rotating rod 651 drives the first convex ring 653 and the second convex ring 654 to rotate. Through the limiting of the wedge-shaped push rod 632 by the first convex ring 653, the squeezing of the extrusion wedge block 641 by the second convex ring 654, the locking of the spring locking pin 11 and the locking groove 13, and the limiting of the pressure plate 652 by the U-shaped locking pin 9, multiple limiting and locking are formed, which enhances the stability of the locking assembly 63 and further ensures the tight locking of the U-shaped locking block 631 with the upper and lower flanges 4, effectively improving the overall stability and vibration resistance of the connection between the box cover 2 and the box body 1.

[0058] Finally, the rectangular through plate 14 is installed on the flange 4 on the cover 2 by bolts 15, which not only enhances the overall strength of the connection structure between the cover 2 and the body 1, but also forms secondary protection for the locking assembly 63 and the positioning assembly 8; effectively blocking external impurities such as dust and moisture from entering the battery pack; and further improving the sealing and protection performance of the battery pack.
