Description

Technical Field

[0001] The present invention relates to the field of lithium batteries, and more specifically, to a lithium battery module and a battery swapping device. Background Art

[0002] In the current new energy vehicle market, most new energy vehicles choose lithium batteries as the energy source. Compared with fuel vehicles, new energy vehicles have better environmental friendliness. One of the main obstacles restricting users from purchasing new energy vehicles is the charging efficiency of new energy vehicles. Limited by the characteristics of chemical batteries, the charging efficiency of new energy vehicles is not high, and it usually takes several hours to charge, which undoubtedly reduces the application range of new energy vehicles. To address the problem of low charging efficiency of new energy vehicles, battery swapping new energy vehicles have been introduced in the current market. By swapping the entire lithium battery assembly of new energy vehicles, an experience similar to refueling a fuel vehicle can be achieved, thereby eliminating consumers' concerns and increasing the popularity of new energy vehicles.

[0003] The structure of existing lithium battery modules usually includes a housing. Inside the housing, multiple battery cells are arranged. After the positive and negative electrodes of each battery cell are set according to the output specification requirements, the battery cells are connected by flexible connecting wires. At the same time, by using a welding method, the flexible connecting wires are connected to the output conductive posts arranged on the housing. Then, the entire lithium battery module outputs power through the connecting conductive terminals on the conductive posts, making multiple lithium batteries present a whole lithium battery module. When a single or multiple battery cells inside the lithium battery module bulge and are damaged, the entire battery module needs to be replaced, or the battery cells inside the lithium battery module need to be disassembled and removed throughout the process, resulting in a high cost for replacing the lithium battery module and a low safety factor.

[0018] 1. In this solution, by setting up the battery module assembly, multiple batteries can work simultaneously, enabling efficient and rapid assembly during the assembly of the battery module.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 to 8 , a lithium battery module and a battery swapping device, including an electric slide rail 1, an electric slider 2 is slidably connected inside the electric slide rail 1, a lifting push rod 3 is fixedly connected to the upper surface of the electric slider 2, an output end of the lifting push rod 3 is fixedly connected to an L-shaped plate 4, a battery swapping assembly 6 is fixedly connected to the bottom of the L-shaped plate 4, and a battery module assembly 5 is arranged above the battery swapping assembly 6.

[0040] As Figure 2 and Figure 3 shown, the battery module assembly 5 includes two first side plates 51 arranged, two second side plates 52 are inserted between the two first side plates 51, a battery 514 is inserted between the two first side plates 51, fourth springs 58 are fixedly connected to the four corners on one side of the second side plate 52, a pressing plate 55 is fixedly connected to one side of the fourth spring 58, fixing blocks 53 are fixedly connected to both sides of the upper surface of the second side plate 52, a first through groove 510 is opened inside the fixing block 53, a fixing plate 59 is fixedly connected to the inner surface of the first through groove 510, a engaging block 512 is slidably connected inside the first through groove 510, a second through groove 515 is opened inside the engaging block 512, a fifth spring 511 is fixedly connected to the inner surface of the second through groove 515, a card slot 513 is opened on one side of the engaging block 512, and a bus bar plate 54 is inserted into the card slot 513.

[0041] An automatic detachment component 56 is fixedly connected between the two bus bar plates 54. Bevels are arranged on the upper and lower surfaces of the engaging block 512 close to one side of the card slot 513. The fifth spring 511 is located inside the first through groove 510 and is fixedly connected to the fixing plate 59. The bus bar plate 54 is located directly above the electrode of the battery 514. The battery 514 is located between the two pressing plates 55 and is clamped and fixed by the pressing plates 55. Support legs are fixedly connected to both sides of the electric slide rail 1.

[0042] Combine the two first side plates 51 and the two second side plates 52 into a frame, and fix the first side plate 51 and the second side plate 52 with locking bolts. Place multiple batteries 514 in the frame assembled by the first side plate 51 and the second side plate 52 in sequence. The two pressing plates 55 squeeze both sides of the multiple batteries 514 under the elastic force of the fourth springs 58, preventing the batteries 514 from sliding inside the second side plate 52. After the batteries 514 are assembled, press the two bus bar plates 54 onto the electrodes of the batteries 514. The two sides of the bus bar plate 54 will first contact the hypotenuse of the engaging block 512. When the bus bar plate 54 moves downward, it will squeeze the engaging block 512 to move inside the fixing block 53, squeezing the fifth spring 511. When the bus bar plate 54 passes through the hypotenuse of the engaging block 512, under the elastic force of the fifth spring 511, the engaging block 512 quickly resets, buckling the card slot 513 on one side of the bus bar plate 54 to firmly fix the bus bar plate 54. At the same time, the bus bar plate 54 contacts the electrodes on the multiple batteries 514, enabling the multiple batteries 514 to work simultaneously. This allows for effective and rapid assembly when assembling the battery 514 module. At the same time, under the buckling of the multiple engaging blocks 512, the bus bar plate 54 is effectively fixed, preventing the bus bar plate 54 from separating from the electrodes of the battery 514, which could cause poor contact between the bus bar plate and the battery electrodes and result in a power outage.

[0043] As Figure 3 - Figure 5 shown, the automatic detachment component 56 includes a telescopic rod 562 fixed to one side of the bus bar plate 54, two transmission racks 564 fixed to one side of the extrusion plate 55, two trapezoidal rods 565 fixed to the upper surface of the extrusion plate 55, and two storage grooves 569 opened on the upper surface of the second side plate 52. A sleeve 561 is sleeved on the outer surface of the two telescopic rods 562. A first spring 566 is fixedly connected to the side of the two telescopic rods 562 close to each other. Two transmission gears 563 are rotatably connected to the lower surface of the sleeve 561. The transmission gears 563 are meshed with the transmission racks 564. A third spring 5610 is fixedly connected to the inner bottom of the storage groove 569. A top block 567 is fixedly connected to the top of the third spring 5610. A support block 5611 is slidably connected to one side of the top block 567. A second spring 568 is fixedly connected to one side of the support block 5611.

[0044] The trapezoidal rod 565 is located above the second side plate 52. One side of the second spring 568 is in contact with the hypotenuse of the trapezoidal rod 565. The top block 567 is located inside the storage groove 569 and slides. The tooth surfaces of the two transmission racks 564 on different sides are arranged opposite to each other. The transmission gears 563 are located between the two transmission racks 564 and are meshed with each other. The first spring 566 is located inside the sleeve 561. Both the third spring 5610 and the first spring 566 are in a stretched state. Limiting components 57 are fixedly connected to both sides of the sleeve 561.

[0045] When the lithium battery module is working normally, the battery may experience an excessive internal temperature, resulting in the battery bulging. If it continues to be used, the battery temperature will rise again and cause spontaneous combustion, seriously endangering life and property safety. Therefore, an automatic detachment component 56 is provided between the two busbar plates 54. When the internal temperature of the battery 514 is too high and bulges, one of the batteries 514 will push the adjacent batteries 514 to both sides. Eventually, the battery 514 will push the extrusion plate 55. The extrusion plate 55 will drive the two transmission racks 564 to move. The movement of the battery 514 drives the transmission gear 563, and at the same time drives the extrusion plate 55 on the other side to move closer to the side away from the battery 514. The movement of the extrusion plate 55 synchronously drives the trapezoidal rod 565 to approach the support block 5611, and makes the hypotenuse of the support block 5611 come into contact with the trapezoidal rod 565. As the trapezoidal rod 565 moves, the trapezoidal rod 565 pushes the support block 5611 to move into the inside of the stop block 567. When the support block 5611 completely enters the inside of the stop block 567, at this time the stop block 567 loses the effect of limit support. At this time, under the pulling of the third spring 5610, the stop block 567 quickly contracts into the receiving groove 569. At this time, the two busbar plates 54 lose their limiting effect and quickly move closer to the middle, causing the two busbar plates 54 to move away from the battery 514 electrodes, stopping the battery 514 from working, avoiding the aggravation of high temperature and high pressure caused by continuous operation, and even causing an explosion, effectively improving the safety of the lithium battery module and protecting the life and property safety of users.

[0046] As Figure 4 shown, the limit component 57 includes an internal thread plate 571 fixed on one side of the sleeve 561 and a sliding groove 574 opened in the middle of the upper surface of the extrusion plate 55. A threaded rod 572 is threadedly connected inside the internal thread plate 571. The bottoms of the two threaded rods 572 are connected to a clamping plate 573 through bearings. The clamping plate 573 is located inside the two sliding grooves 574.

[0047] In actual use, the battery module may experience accidental bumps. Only by limiting the battery 514 motor through the busbar plate 54, it is easy for the busbar plate 54 to bend, resulting in poor contact between the busbar plate 54 and the battery 514 electrode, causing accidental power off of the battery and giving users a bad experience. Therefore, after the battery 514 is assembled, at this time, the two threaded rods 572 are rotated. Under the action of the thread, the threaded rods 572 drive the two clamping plates 573 to move downward, so that the clamping plates 573 slide inside the two sliding grooves 574. At this time, the clamping plates 573 gradually approach and contact the top of the battery 514. At this time, stop rotating the threaded rods 572 to avoid the clamping plates 573 applying too much pressure on the battery 514, resulting in the inability of the battery 514 to push other batteries 514 to move when bulging, further ensuring the reliability of the battery module.

[0048] like Figure 6 and Figure 7 As shown, a battery exchange device includes a battery exchange component 6, which includes a base 61 fixed at the bottom of two L-shaped plates 4, one side of the base 61 is fixedly connected to a support plate 62, two fourth through grooves 611 are provided inside the support plate 62, the fourth through grooves 611 have internal sliding connecting plates 64, two sliding rods 63 are slidingly connected at the middle of the top of the support plate 62, one side of the two sliding rods 63 is fixedly connected to a cross plate 65, one side of the cross plate 65 has two plate grooves 66, one end of the lower surface of the connecting plate 64 is hinged with a hinged plate 68, the lower surface of the connecting plate 64 is fixedly connected with a baffle 69, the base 61 is internally slidingly provided with an anti-dumping component 67, and the top of the support plate 62 away from the base 61 is fixedly connected to a driving component.

[0049] The driving component includes a dual-axis motor 614 fixed on the top of the support plate 62 away from the base 61 and a rack 610 fixed on the lower surface of the connecting plate 64. The output end of the dual-axis motor 614 is fixedly connected to a driving rod 613, and the two driving rods 613 are fixedly connected to a driving gear 612 on the side away from each other.

[0050] A rack groove is formed on the lower surface of the connecting plate 64 , a rack 610 is located at the top of the rack groove, the rack 610 is meshed with the driving gear 612 , the baffle 69 is located in front of the hinge plate 68 , and one side of the connecting plate 64 extends to the inside of the plate groove 66 .

[0051] When a battery needs to be replaced, the battery to be replaced is located on the battery rack. Due to the heavy weight of the battery, it is easy to be unstable when taking the battery from a high place, causing the battery to fall and injure the user, and the battery is easily damaged, increasing the cost of replacement;

[0052] Therefore, a battery replacement device is provided to better access the battery at a high position. When accessing the battery at a high position, through the cooperation of the lifting push rod 3 and the L-shaped plate 4, the base 61 is driven to a height flush with the bottom of the battery. Then, the double-shaft motor 614 is turned on to work. The two driving rods 613 drive the two driving gears 612 to rotate. The driving gear 612 drives the connecting plate 64 to move towards the battery rack through the rack 610. The connecting plate 64 drives the hinge plate 68 to approach the battery. When the hinge plate 68 touches the battery, the hinge plate 68 rotates, so that when the connecting plate 64 moves, one end of it can smoothly pass above the battery 514. When the hinge plate 68 passes above the battery 514, the hinge plate 68 automatically falls to a vertical state. At this time, the double-shaft motor 614 is reversed, and the connecting plate 64 is driven to move in the reverse direction through transmission. The connecting plate 64 drives the hinge plate 68 to contact one side of the battery. Since the hinge plate 68 is blocked by the baffle 69, the hinge plate 68 cannot deflect. The connecting plate 64 pulls the battery 514 to move through the hinge plate 68 and move towards the base 61. The battery 514 slides on the base 61 and stably moves above the base 61. The battery replacement device can safely and quickly remove the battery at a high position, reduce the accidents caused by manually removing the battery at a high position, improve the safety of the user, and further improve the flexibility of the battery replacement device.

[0053] As Figure 8 shown, the anti-tipping component 67 includes a transmission column 675 sliding in the middle of the base 61 and a limiting strip 671 sliding on both sides of the base 61. A frustum 673 is fixedly connected to the top of the transmission column 675, a pulling plate 674 is fixedly connected to the bottom of the transmission column 675. A sixth spring 676 is sleeved on the outer surface of the transmission column 675. Second cylinders 679 are fixedly connected to both sides of the pulling plate 674. Two fixing rods 678 are fixedly connected to the lower surface of the base 61. An articulated rod 6710 is hinged to the bottoms of the two fixing rods 678. Third through grooves 677 are opened on both sides inside the articulated rod 6710. A first round rod 672 is fixedly connected to the bottom of the limiting strip 671.

[0054] A receiving groove is opened in the middle of the upper surface of the base 61. The frustum 673 is adapted to the receiving groove. The top of the sixth spring 676 is fixedly connected to the lower surface of the base 61. The first round rod 672 is located inside the third through groove 677 and slides with each other. The second cylinder 679 is located inside the third through groove 677 and slides with each other.

[0055] When the battery 514 moves smoothly above the base 61 and moves downward, when the battery 514 moves onto the base 61, if the battery 514 is offset when moving onto the base 61, when the battery 514 completely moves onto the base 61, the battery 514 may be at the edge of the base 61. If the base 61 is not stable during the downward movement, it will cause the battery 514 to shake on the base 61, resulting in the battery 514 falling off the base 61 and causing damage to the battery 514. Therefore, when the battery 514 moves onto the base 61, one side of the battery 514 contacts the inclined surface of the frustum 673 and is gradually squeezed into the internal receiving groove of the base 61, allowing the battery 514 to move smoothly onto the base 61. When the frustum 673 moves downward, the pull plate 674 is driven to move downward through the transmission column 675, so that the synchronously move downward at the ends where the two hinge rods 6710 approach each other. The two hinge rods 6710 rotate around the hinge of the fixed rod 678, causing the other end of the hinge rod 6710 to push the limit strip 671 upward to limit and block both sides of the base 61. When the battery 514 moves onto the base 61 initially, it is limited by the limit strip 671, which can prevent the battery 514 from shifting and falling off the base 61.

[0056] Usage method: First, by pressing down the busbar plate 54, under the action of the engaging block 512, the busbar plate 54 can be quickly fixed, and the installation is convenient. Through the cooperation of the components of the automatic detachment assembly 56, when the battery 514 bulges, the transmission trigger block 567 is retracted into the receiving groove 569, and the busbar plate 54 can be timely moved away from the electrode. With the cooperation of the components of the limiting assembly 57, the position above the battery 514 can be limited to improve the stability of the battery 514.

[0057] Then, through the battery replacement assembly 6, the battery 514 can be quickly removed, reducing the safety hazards existing in manual battery removal. Through the action of the anti-tipping assembly 67, when the battery 514 moves onto the base 61, it can be well limited to avoid the battery 514 shifting and falling off the base 61.

[0058] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
