Description

Technical Field

[0001] The invention relates to a distributed balancing structure, in particular to a distributed balancing structure used for vehicle driving, and belongs to the technical field of automobiles. Background Art

[0002] The vehicle distributed balancing structure is a structure that distributes the vehicle's load or work tasks to multiple operating units. Common vehicle distributed balancing structures include distributed drive systems, distributed braking systems, distributed suspension systems, and distributed battery management systems. The purpose of these distributed balancing structures is to achieve better performance, efficiency, and reliability by distributing the load to multiple units. They can improve the vehicle's handling, stability, and safety, while also optimizing energy utilization and extending component life.

[0003] In electric vehicles, the distributed battery management system can monitor and manage the status of each battery module to ensure the safety and performance of the battery module. In the design and use of the distributed battery management system, in order to ensure the sealing performance of the battery pack, during the assembly process, multiple sets of bolts are used to fix the battery box and the outer periphery of the battery cover. The bolts need to be installed separately. Although the sealing performance of the battery pack is guaranteed, it is time-consuming and laborious during the disassembly and assembly process. In addition, when assembling the battery module, the battery module is positioned using the limit frame at the bottom of the battery box. The shape of the limit frame is fixed, and the shape of the battery module may have certain inconsistencies, and it cannot be guaranteed to fit closely with the limit frame, affecting the stability of the battery module.

[0004] Therefore, a distributed balancing structure for vehicle driving is designed to optimize the above problems. Summary of the invention

Afterwards, they mesh with the large gears on the adjacent pressure plates, so that during the installation process, only the rotation of one set of rotating components needs to be controlled to realize the simultaneous rotation of the bolts inside multiple sets of pressure plates, further improving the assembly rate.

DETAILED DESCRIPTION

[0030] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0031] like Figure 1-Figure 8 As shown, this embodiment provides a distributed balancing structure for vehicle driving, including a battery box 1, a limit frame 2 installed at the bottom of the battery box 1 to separate the intervals, a battery module 4 installed inside the limit frame 2, a liquid cooling module 3 located at the bottom of the battery module 4, and a battery cover 5 fixedly installed on the top of the battery box 1, an upper frame plate 6 is horizontally fixed to the top of the outer side of the battery box 1, a slot 7 is opened on the top of the upper frame plate 6 around the outer side of the battery box 1, threaded holes 8 are evenly opened on the inner bottom of the slot 7, and a stamping groove 9 is provided on the outer side of the battery cover 5 to be wedged with the slot 7, The inner bottom of the stamping groove 9 is evenly provided with through holes 10 that match the threaded holes 8. A pressure plate 11 is provided inside the stamping groove 9. The ends of multiple groups of pressure plates 11 are connected to each other. A driven gear 13 is evenly installed on the inner bottom of the pressure plate 11 for rotation along the length direction. A bolt 12 is vertically slidably provided inside the driven gear 13, and the bolt 12 passes through the bottom of the pressure plate 11. A toothed belt 14 is provided between the driven gears 13. A rotating assembly 15 for controlling the rotation of the toothed belt 14 is provided at the inner end of the pressure plate 11. An extrusion mechanism for pressing and positioning the battery module 4 is provided on the side of the limit frame 2.

[0032] Overall working principle: As an important component of the distributed battery management system, the battery pack is first assembled by fixing the limit frame 2 horizontally at the bottom of the battery box 1, then installing the liquid cooling module 3 below the battery module 4, and then placing the battery module 4 inside the interval separated by the limit frame 2 to limit the position of the battery module 4. After the battery is placed, the battery module 4 is squeezed and limited by the extrusion mechanism, and the controller is installed at the front end of the battery box 1. Finally, the battery cover 5 is covered on the top of the battery box 1. The protrusion at the bottom of the stamping groove 9 on the battery cover 5 is stuck in the slot 7 of the upper frame plate 6 to increase the contact area with the upper frame plate 6. At the same time, the through hole 10 is aligned with the threaded hole 8, and then multiple groups of pressing plates 11 are respectively inserted into the top of the stamping groove 9. The bolts 12 at the bottom of the pressing plate 11 pass through the through hole 10 and are aligned with the threaded hole 8. Then, the rotating assembly 15 is used to simultaneously control the simultaneous rotation of the multiple groups of bolts 12, so that the multiple groups of bolts 12 inside the pressing plate 11 are simultaneously tightened to the inside of the threaded hole 8 to quickly position the battery cover 5.

[0033] In this embodiment, sliding holes 18 are formed through the upper and lower ends of the driven gear 13, and the bolt 12 passes through the inside of the sliding hole 18. A guide groove 17 is vertically formed on the outside of the bolt 12, and a spline is fixed on the inside of the sliding hole 18, and the spline is located inside the guide groove 17.

[0034] Partial working principle: The bolt 12 passes through the driven gear 13, and due to the mutual cooperation between the spline and the guide groove 17, the bolt 12 can only slide vertically inside the sliding hole 18, so that when the driven gear 13 controls the bolt 12 to rotate, the bolt 12 can automatically move downward.

[0035] In this embodiment, a limit block 16 is fixedly mounted on the top end of the bolt 12 , and the outer diameter of the limit block 16 is greater than the inner diameter of the sliding hole 18 .

[0036] Partial working principle: During the downward movement of the bolt 12 , the limit block 16 can limit the downward movement distance of the bolt 12 to prevent the bolt 12 from separating from the inside of the pressure plate 11 .

[0037] In this embodiment, the rotating assembly 15 includes an adjusting rod 19, a small gear 20 and a large gear 21. The adjusting rod 19 is rotatably installed on the inner bottom of the pressure plate 11. The top of the adjusting rod 19 passes through the pressure plate 11. The small gear 20 is fixed to the bottom end of the adjusting rod 19. The outer side of the small gear 20 is meshed with the inner side of the toothed belt 14. The large gear 21 is installed on the top of the adjusting rod 19, and the outer side of the large gear 21 protrudes from the end of the pressure plate 11.

[0038] Local working principle: During the installation of the bolts 12, by controlling the rotation of the adjusting rod 19, the adjusting rod 19 will drive the small gear 20 to rotate. The small gear 20 is connected to the driven gear 13 through the toothed belt 14, and can drive the driven gear 13 to rotate at the same time, thereby realizing the simultaneous installation of multiple groups of bolts 12. After the pressure plate 11 is installed inside the stamping groove 9, the protruding parts of the large gear 21 on the two adjacent groups of pressure plates 11 are meshed with each other. Therefore, during the adjustment process, only controlling the rotation of one group of adjusting rods 19 can control the installation of the bolts 12 inside multiple groups of pressure plates 11.

[0039] In this embodiment, the top end of the adjusting rod 19 is flush with the surface of the pressing plate 11 , and a straight groove 22 is formed on the top of the pressing plate 11 .

[0040] Partial working principle: When the adjusting rod 19 is rotated and controlled, a flat-blade screwdriver is inserted into the inside of the slot 22 to rotate the adjusting rod 19, which is more convenient to use.

[0041] In this embodiment, the extrusion mechanism includes a cavity 23, a sleeve 24, a first piston 25, a push rod 26 and an inflation component 27. The cavity 23 is opened inside the limit frame 2, and the shape of the cavity 23 is the same as the shape of the limit frame 2. The sleeve 24 is evenly fixed on the side of the limit frame 2. One end of the sleeve 24 extends to the inside of the cavity 23, and the other end of the sleeve 24 is flush with the side of the limit frame 2. The first piston 25 is slidably installed inside the sleeve 24, and the push rod 26 is fixed on the end of the first piston 25 facing the outside of the sleeve 24. An inflation component 27 for inflating the inside of the cavity 23 is provided on the outside of the battery box 1.

[0042] Local working principle: After the battery module 4 is placed, the interior of the cavity 23 is inflated using the inflation assembly 27. The pressure inside the cavity 23 increases, which will push the first piston 25 to slide outward. The push rod 26 on the side of the first piston 25 will protrude to the outside of the limit frame 2 and squeeze to the side of the battery module 4, thereby squeezing the battery module 4 into position.

[0043] In this embodiment, a limiting ring 28 is fixed on the inner side of the outer end of the sleeve 24 , and the inner diameter of the limiting ring 28 is smaller than the outer diameter of the first piston 25 .

[0044] Partial working principle: In order to prevent the first piston 25 from falling out, a limiting ring 28 is used to limit the sliding distance of the first piston 25, which is more practical.

[0045] In this embodiment, a rubber pad 29 is fixed to one end of the push rod 26 away from the first piston 25 , and an anti-slip pattern is provided on the outer side of the rubber pad 29 .

[0046] Partial working principle: The rubber pad 29 on the contact surface between the push rod 26 and the battery module 4 can effectively avoid damage to the surface of the battery module 4, and increase the friction with the surface of the battery module 4, thereby ensuring the stability of the battery module 4.

[0047] In this embodiment, the inflation assembly 27 includes a lower frame plate 30, a cylinder 31, a second piston 32, an air groove 34 and a shunt pipe 35. The lower frame plate 30 is fixed to the bottom of the outer side of the battery box 1. The cylinder 31 is evenly fixed between the top of the lower frame plate 30 and the upper frame plate 6, and the top of the cylinder 31 is connected to the threaded hole 8. The second piston 32 is vertically slidably arranged inside the cylinder 31. The lower frame plate 30 is provided with an air groove 34 connected to the bottom of the cylinder 31, and a shunt pipe 35 is provided between the air groove 34 and the cavity 23.

[0048] Local working principle: After the bolt 12 passes through the threaded hole 8, it will move downward to squeeze the second piston 32 downward. The downward movement of the second piston 32 will squeeze the gas inside the cylinder 31, and the gas will enter the cavity 23 through the gas groove 34 and the diverter pipe 35, increasing the pressure inside the cavity 23.

[0049] In this embodiment, a return spring 33 is provided between the bottom of the second piston 32 and the inner bottom of the cylinder 31 , and the initial length of the return spring 33 is the same as the length of the cylinder 31 .

[0050] Partial working principle: When the second piston 32 moves downward, the return spring 33 will be compressed. After the battery cover 5 is removed, the second piston 32 can automatically return to its original position so that the battery module 4 can be quickly taken out.

[0051] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
