Description

Technical Field

[0001] This application relates to the field of pallets, and more particularly to an assembly and positioning structure for an integral outer frame and a separate inner liner. Background Technology

[0002] Cell trays are core tooling used to support and secure cell cells during the production and transportation of new energy batteries. They prevent cell collisions and displacement, thus adapting to the production needs of different cell processes.

[0003] The existing battery cell tray includes an outer frame and an inner liner. The inner liner is fixed to the inner wall of the outer frame by bolts, and the battery cells are embedded between adjacent inner liners. However, the battery cell tray is easily subjected to vibration and impact during production line conveying, stacking, handling, and repeated handling of battery cells. The inner liner is prone to misalignment and impact on the bolts, causing the bolts to loosen. The positioning of the inner liner fails, causing the battery cells to shift or collide within the outer frame. This makes it impossible to complete the accurate transfer and assembly of the battery cells, thereby reducing the assembly accuracy of the battery cells. Summary of the Invention

[0004] To improve the assembly precision of battery cells, this application provides an assembly positioning structure for an integrated outer frame and a separate inner liner.

[0005] This application provides an assembly and positioning structure for an integrated outer frame and a separate inner lining, which adopts the following technical solution: An assembly and positioning structure for an integrated outer frame and a split inner liner includes a frame body, multiple inner liner plates, and multiple locking assemblies. The frame body has an assembly cavity, and the multiple inner liner plates are spaced apart and embedded in the inner wall of the assembly cavity. An assembly gap is left between adjacent inner liner plates for embedding a power supply core. The locking assemblies correspond one-to-one with and are connected to the inner liner plates. Each locking assembly includes a locking pin and a locking bolt. The end of the locking pin is connected to the surface of the inner liner plate. The inner wall of the assembly cavity has a locking hole for the locking pin to be embedded. The surface of the frame body has a locking cavity for the locking bolt to pass through. The locking cavity is connected to the assembly cavity. The surface of the inner liner plate has a threaded hole for tightening the locking bolt. The locking bolt and the locking pin are located on both sides of the thickness direction of the inner liner plate.

[0006] By adopting the above technical solution, when the inner liner is embedded in the assembly cavity, the locking pin is embedded in the locking hole, and the outer circumferential surface of the locking pin abuts against the inner wall of the locking hole to form a positioning. At the same time, the locking cavity is connected to the threaded hole, and the shank of the locking bolt passes through the locking cavity and is threaded onto the inner wall of the threaded hole. This enables the inner liner to be detachably installed on the inner wall of the assembly cavity, allowing the size of the assembly gap to be adjusted according to the thickness of the battery cell, thereby improving the versatility of the battery cell tray. Meanwhile, the locking pin and the locking bolt are located on both sides of the thickness direction of the inner liner, so that the inner liner forms a bidirectional clamp in the thickness direction, avoiding the loosening and displacement of the locking bolt caused by the misalignment of the inner liner on the inner wall of the assembly cavity, and ensuring that the battery cell tray can maintain the accuracy and stability of the battery cell within the assembly gap during long-term use.

[0007] Optionally, the locking assembly further includes a locking rod and an elastic element. The surface of the locking pin has a slide for the locking rod to slide. The sliding direction of the locking rod is perpendicular to the axis of the locking pin. The inner wall of the locking hole has a limiting groove for the end of the locking rod to be inserted. One end of the elastic element in the elastic direction is connected to the inner wall of the limiting groove, and the other end of the elastic element in the elastic direction is connected to the surface of the locking rod. The elastic element has a tendency to force the end of the locking rod to be inserted into the limiting groove.

[0008] By adopting the above technical solution, when the locking pin is embedded in the locking hole, the limiting groove connects to the slide, and the elastic element drives the locking rod to slide towards the limiting groove. The end of the locking rod is embedded in the limiting groove, and the outer circumferential surface of the locking rod abuts against the inner wall of the limiting groove to form a limit, making it difficult for the locking pin to come out of the locking hole, thereby improving the limiting stability of the locking pin in the locking hole.

[0009] Optionally, the locking assembly further includes a sliding ring, which is coaxially sleeved on the outer circumferential surface of the locking pin. The sliding ring slides along the axis of the locking pin. The inner wall of the sliding ring abuts against the surface of the locking rod and limits the locking rod within the slide rail. The surface of the sliding ring has a clearance cavity for the locking rod to pass through. The clearance cavity penetrates the outer wall of the sliding ring and connects to the inner cavity of the sliding ring. When the clearance cavity connects to the slide rail and the limiting groove, the end of the locking rod can pass through the clearance cavity and be embedded in the limiting groove.

[0010] By adopting the above technical solution, when the inner liner is stored, the sliding ring is driven to slide along the locking pin axis toward the slideway. The sliding ring abuts against the locking rod surface toward the inner wall of the slideway and limits the locking rod within the slideway. When the inner liner is embedded in the inner wall of the assembly cavity and the locking pin is embedded in the locking hole, the sliding ring is driven to slide along the locking pin axis toward the direction away from the slideway. The clearance cavity connects the slideway and the limiting groove. The elastic force of the elastic element drives the end of the locking rod to pass through the clearance cavity and embed into the limiting groove, thereby realizing the directional sliding of the locking rod within the slideway.

[0011] Optionally, the locking hole penetrates the surface of the frame, and the locking assembly further includes a retaining ring. The outer ring wall of the retaining ring is connected to the inner wall of the locking hole. When the locking pin is embedded in the locking hole, the ring surface of the retaining ring abuts against the ring surface of the sliding ring and pushes the sliding ring closer to the inner liner. The clearance cavity connects the slide and the limiting groove.

[0012] By adopting the above technical solution, when the inner liner is embedded in the assembly cavity and the locking pin is embedded in the locking hole, the abutting ring surface abuts against the sliding ring surface and pushes the sliding ring closer to the inner liner. The clearance cavity connects the slide and the limiting groove, realizing the directional sliding of the sliding ring. There is no need for the staff to manually control the sliding ring, thereby improving the ease of installation of the inner liner.

[0013] Optionally, the locking assembly further includes an elastic element two, one end of which is connected to the surface of the inner liner plate in the direction of elastic force, and the other end of which is connected to the surface of the sliding ring in the direction of elastic force. The elastic element two has the elastic force to drive the sliding ring to slide away from the inner liner plate, and the inner wall of the sliding ring abuts against the surface of the locking rod and confines the locking rod within the slide rail.

[0014] By adopting the above technical solution, when the locking rod is pushed to slide towards the locking pin, the end of the locking rod disengages from the limiting groove and the clearance cavity in sequence, causing the inner liner to disengage from the assembly cavity. The abutment effect of the clamping ring on the sliding ring disappears, and the elastic force of the elastic element drives the sliding ring to slide away from the inner liner. The inner wall of the sliding ring abuts against the locking rod surface and limits the locking rod in the slide, thereby realizing the directional sliding of the sliding ring.

[0015] Optionally, a force-applying component is connected between the locking rod and the locking pin. The force-applying component includes a force-applying rod. The end face of the locking pin away from the inner liner plate has a force-applying cavity. The force-applying cavity is connected to a slide. One end of the force-applying rod passes through the force-applying cavity, is embedded in the slide, and is connected to the surface of the locking rod. The other end of the force-applying rod protrudes from the surface of the locking pin.

[0016] By adopting the above technical solution, when the inner liner needs to be disassembled, the end of the force-applying rod protrudes from the locking pin to provide a force-applying point. The force-applying rod pushes the locking rod to slide along the inner wall of the slideway away from the limiting groove. The end of the locking rod disengages from the limiting groove and the clearance cavity in sequence. The limiting effect of the locking rod on the sliding ring disappears. The elastic force of the elastic element drives the sliding ring to slide along the axis of the locking pin towards the inner liner. The inner wall of the sliding ring abuts against the surface of the locking rod and limits the locking rod in the slideway, reducing the wear between the locking rod and the sliding ring, thereby extending the service life of the battery cell tray.

[0017] Optionally, the inner diameter of the sliding ring is smaller than the inner diameter of the clamping ring. The force application component also includes a limiting plate. The end of the limiting plate is rotatably connected to the end face of the force application rod protruding from the locking pin. The rotation axis of the limiting plate and the sliding direction of the locking rod are parallel to each other. The inner ring wall of the sliding ring away from the elastic element two has a positioning groove for the end of the limiting plate to be inserted. When the limiting plate rotates towards the positioning groove and is inserted, the surface of the limiting plate abuts against the inner wall of the positioning groove to form a limit. The end of the locking rod sequentially disengages from the limiting groove and the clearance cavity and is located in the slide.

[0018] By adopting the above technical solution, when the inner liner is disassembled, the force rod drives the locking rod to slide along the inner wall of the slideway towards the locking pin. The end of the locking rod sequentially disengages from the limiting groove and the clearance cavity and is located in the slideway. The end of the limiting plate away from the force rod faces the positioning groove, driving the limiting plate to rotate towards the positioning groove. The end of the limiting plate is embedded in the positioning groove. The surface of the limiting plate abuts against the inner wall of the positioning groove and limits the sliding of the locking rod. At the same time, the inner liner is removed. The elastic force of the elastic element drives the sliding ring to slide along the axis of the locking pin away from the inner liner. The inner wall of the positioning groove abuts against the surface of the limiting plate and guides the limiting plate to disengage from the positioning groove. The limiting effect of the limiting plate on the force rod disappears, and the inner wall of the sliding ring 35 abuts against the surface of the locking rod and limits the locking rod to the slideway, thus achieving the limiting stability of the locking rod in the slideway.

[0019] Optionally, the force-applying component further includes an elastic element three, the elastic coefficient of the elastic element three being less than that of the elastic element two, one end of the elastic element three in the elastic force direction being connected to the rotating shaft of the limiting plate, and the other end of the elastic element three in the elastic force direction being connected to the surface of the force-applying rod, the elastic element three having the tendency to elastically drive the end of the limiting plate to rotate toward the positioning groove and embed.

[0020] By adopting the above technical solution, when the force-applying rod slides along the inner wall of the force-applying cavity toward the positioning groove, the end of the limiting plate faces the positioning groove. The elastic force of the third elastic element drives the end of the limiting plate to rotate toward the positioning groove and embed. The surface of the limiting plate abuts against the inner wall of the positioning groove and limits the sliding of the locking rod. At the same time, the elastic coefficient of the second elastic element is greater than that of the third elastic element. When the elastic force of the second elastic element drives the sliding ring to slide along the locking pin axis toward the direction away from the inner liner, the inner wall of the positioning groove abuts against the surface of the limiting plate and guides the limiting plate to disengage from the positioning groove, thereby realizing the directional embedding of the limiting plate in the positioning groove.

[0021] Optionally, the force-applying component further includes a slider connected to the inner wall of the sliding ring. The surface of the locking pin has a groove for the slider to slide, and the sliding direction of the slider is parallel to the axis of the locking pin.

[0022] By adopting the above technical solution, when the sliding ring slides along the locking pin axis, the slider slides on the inner wall of the groove, making it difficult for the sliding ring to deflect during the sliding process along the locking groove axis, thereby ensuring the stability of the positioning groove orientation.

[0023] Optionally, the locking rod includes a rod portion and a roller portion, the roller portion being rotatably connected to one side of the rod portion along its axial direction, the elastic element being located on the side of the rod portion away from the roller portion along its axial direction, and the roller surface of the roller portion being in rolling contact with the inner wall of the sliding ring.

[0024] By adopting the above technical solution, the elastic element drives the end of the rod with the roller to be embedded in the limiting groove. When both the roller and the rod are located in the slide, the roller surface of the roller makes rolling contact with the inner wall of the sliding ring. Rolling friction replaces sliding friction, reducing the wear between the locking rod and the sliding ring, thereby extending the service life of the battery cell tray.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The locking pins and locking bolts enable the inner liner to form a bidirectional clamping in the thickness direction, preventing the locking bolts from loosening or shifting due to misalignment of the inner liner on the inner wall of the assembly cavity, and ensuring that the cell tray can maintain the precision and stability of the cells within the assembly gap during long-term use. The locking rod and the elastic element are designed such that the outer circumferential surface of the locking rod abuts against the inner wall of the limiting groove to form a limit, making it difficult for the locking pin to disengage from the locking hole, thereby improving the limiting stability of the locking pin in the locking hole; The sliding ring is designed so that the clearance cavity connects the slide rail and the limiting groove. The elastic element drives the end of the locking rod to pass through the clearance cavity and embed into the limiting groove, thereby realizing the directional sliding of the locking rod in the slide rail.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses an assembly and positioning structure for an integrated outer frame and a separate inner lining. (Refer to...) Figure 1 and Figure 2 The assembly and positioning structure of the integrated outer frame and the split inner liner includes a frame 1, multiple inner liner plates 2 and multiple locking components 3. The frame 1 has an assembly cavity 11. Multiple inner liner plates 2 are embedded in the inner wall of the assembly cavity 11 at intervals. The arrangement direction of the inner liner plates 2 is parallel to the width direction of the frame 1, and the length direction of the inner liner plates 2 is parallel to the length direction of the frame 1. An assembly gap 21 for the battery core is left between adjacent inner liner plates 2. Two adjacent inner liner plates 2 are respectively pressed against the two sides of the battery core to form a limit, so that the battery core is not easy to shift in the assembly cavity 11, thereby improving the limit stability of the battery core in the assembly gap 21.

[0035] Reference Figure 3 and Figure 4 The locking assembly 3 corresponds to and is connected to the inner lining plate 2. The locking assembly 3 can detachably connect the inner lining plate 2 to the inner wall of the assembly cavity 11. The locking assembly 3 includes a locking pin 31, a locking bolt 32, an elastic element 33, a locking rod 34, a sliding ring 35, a retaining ring 36, and an elastic element 37. The surface of the frame 1 is provided with a locking cavity 12 for the locking bolt 32 to pass through. The locking cavity 12 is connected to the assembly cavity 11, and the axis of the locking bolt 32 in the locking cavity 12 is parallel to the height direction of the frame 1. The inner lining plate 2 is provided with a threaded hole 22 for the locking bolt 32 to be tightened on the plate surface facing the locking cavity 12. The axis of the threaded hole 22 is parallel to the height direction of the frame 1. The rod part 341 of the locking bolt 32 passes through the locking cavity 12 and is threaded and fixed to the inner wall of the threaded hole 22, so as to realize the detachable installation between the inner lining plate 2 and the frame 1.

[0036] Reference Figure 4 and Figure 5The locking pin 31 is integrally formed and fixed to the surface of the inner liner plate 2. The axis of the locking pin 31 is parallel to the height direction of the frame 1. The inner wall of the assembly cavity 11 is provided with a locking hole 13 for the locking pin 31 to be inserted. The locking hole 13 penetrates the surface of the frame 1 along its own axis. When the inner liner plate 2 is inserted into the assembly cavity 11 and the end of the locking pin 31 is inserted into the locking hole 13, the locking cavity 12 is connected to the threaded hole 22. The rod part 341 of the locking bolt 32 passes through the locking cavity 12 and is threaded and fixed to the inner wall of the threaded hole 22, realizing the detachable installation between the inner liner plate 2 and the frame 1. The locking pin 31 and the locking bolt 32 are located on both sides of the thickness direction of the inner liner plate 2, so that the inner liner plate 2 forms a bidirectional clamp in the thickness direction, avoiding the locking bolt 32 from loosening and shifting due to the misalignment of the inner liner plate 2 on the inner wall of the assembly cavity 11, and ensuring that the battery cell tray can maintain the accuracy and stability of the battery cell in the assembly gap 21 during long-term use.

[0037] Reference Figure 4 and Figure 5 The locking pin 31 has a slide 311 on its side wall for the locking rod 34 to slide. The sliding direction of the locking rod 34 is perpendicular to the axis of the locking pin 31. The inner wall of the locking hole 13 has a limiting groove 14 for the end of the locking rod 34 to be inserted. The inner wall of the limiting groove 14 abuts against the outer circumferential surface of the locking rod 34 and limits the locking pin 31 in the locking hole 13. The elastic element 33 can be a compression spring or a tension spring. In this embodiment, the elastic element 33 is a compression spring and has a certain deformation capability. One end of the elastic element 33 in the elastic direction is connected to the inner wall of the limiting groove 14, and the other end of the elastic element 33 in the elastic direction is connected to the rod surface of the locking rod 34. The elastic element 33 has the tendency to drive the end of the locking rod 34 to be inserted into the limiting groove 14.

[0038] Reference Figure 4 and Figure 5 The sliding ring 35 is coaxially sleeved on the outer circumferential surface of the locking pin 31. The sliding ring 35 slides along the axis of the locking pin 31. When both ends of the locking rod 34 are located in the slide rail 311, the inner wall of the sliding ring 35 abuts against the rod surface of the locking rod 34 and limits the locking rod 34 in the slide rail 311, reducing the wear on the locking rod 34 and thus extending the service life of the battery cell tray. The sliding ring 35 has a relief cavity 351 on the surface facing the slide rail 311 for the locking rod 34 to pass through. The relief cavity 351 penetrates the outer wall of the sliding ring 35 and connects to the inner cavity of the sliding ring 35.

[0039] Reference Figure 4 and Figure 5When the sliding ring 35 slides along the axis of the locking pin 31 toward the inner liner plate 2, the clearance cavity 351 connects the slide rail 311 and the limiting groove 14. The elastic element 33 drives the end of the locking rod 34 to pass through the clearance cavity 351 and embed into the limiting groove 14. The inner wall of the limiting groove 14 abuts against the outer circumferential surface of the locking rod 34 to form a limit. At the same time, the rod surface of the locking rod 34 abuts against the inner wall of the clearance cavity 351 and limits the sliding of the sliding ring 35, reducing the wear between the sliding ring 35 and the locking pin 31, thereby further extending the service life of the battery cell tray.

[0040] Reference Figure 4 and Figure 5 The second elastic element 37 can be a compression spring or a tension spring. In this embodiment, the second elastic element 37 is a compression spring, which has a certain deformation capability. One end of the second elastic element 37 in the elastic direction is connected to the surface of the inner liner plate 2, and the other end of the second elastic element 37 in the elastic direction is connected to the ring surface of the sliding ring 35. The second elastic element 37 has the elastic force to drive the sliding ring 35 to slide away from the inner liner plate 2, and the inner wall of the sliding ring 35 abuts against the surface of the locking rod 34 and limits the locking rod 34 to the slide rail 311.

[0041] Reference Figure 4 and Figure 5 The outer ring of the retaining ring 36 is coaxially connected to the inner wall of the locking hole 13. The retaining ring 36 is located on the side of the sliding ring 35 away from the elastic element 37. The inner diameter of the retaining ring 36 is larger than the inner diameter of the sliding ring 35. When the locking pin 31 is inserted into the locking hole 13, the ring surface of the retaining ring 36 abuts against the ring surface of the sliding ring 35 and pushes the sliding ring 35 closer to the inner liner plate 2. The clearance cavity 351 connects the slide 311 and the limiting groove 14. The elastic element 33 drives the locking rod 34 to slide towards the limiting groove 14. The end of the locking rod 34 is inserted into the limiting groove 14. The outer circumferential surface of the locking rod 34 abuts against the inner wall of the limiting groove 14 to form a limit, thereby realizing the directional sliding of the locking rod 34.

[0042] Reference Figure 4 and Figure 5 The locking rod 34 includes a rod portion 341 and a roller portion 342. The roller portion 342 is rotatably connected to one side of the rod portion 341 along its axial direction. The elastic element 33 is located on the side of the rod portion 341 away from the roller portion 342 along its axial direction. The rod portion 341 is slidably connected to the inner wall of the slide rail 311. The axis of the roller portion 342 and the axis of the locking pin 31 are perpendicular to each other, and the sliding direction of the roller portion 342 and the rod portion 341 are perpendicular to each other. The roller surface of the roller portion 342 makes rolling contact with the inner wall of the sliding ring 35. Rolling friction replaces sliding friction, reducing wear between the locking rod 34 and the sliding ring 35, thereby extending the service life of the battery cell tray.

[0043] Reference Figure 4 and Figure 6A force-applying component 4 is connected between the locking rod 34 and the locking pin 31. The force-applying component 4 can control the sliding of the force-applying rod 41. The force-applying component 4 includes the force-applying rod 41, the limiting plate 42, the elastic element 43, and the slider 44. The end face of the locking pin 31 facing away from the inner liner plate 2 in the axial direction has a force-applying cavity 312. The force-applying cavity 312 is connected to the slide rail 311. One end of the force-applying rod 41 in the axial direction passes through the force-applying cavity 312, is embedded in the slide rail 311, and is connected to the rod part 341 near the elastic element 44. The rod surface of the first elastic element 33 has the other end of the force-applying rod 41 protruding from the end face of the locking pin 31. The end of the limiting plate 42 is rotatably connected to the end face of the force-applying rod 41 protruding from the locking pin 31. The rotation axis of the limiting plate 42 and the sliding direction of the rod 341 are parallel to each other. The inner ring wall of the sliding ring 35, which is away from the axis of the second elastic element 37, has a positioning groove 352 for the end of the limiting plate 42 to be inserted. The plate surface of the limiting plate 42 can abut against the inner wall of the positioning groove 352 and limit the sliding of the locking rod 34.

[0044] Reference Figure 4 and Figure 6 The elastic element 43 can be a tension spring or a torsion spring. In this embodiment, the elastic element 43 is a torsion spring, which has a certain deformation capacity. The elastic coefficient of the elastic element 43 is less than that of the elastic coefficient of the elastic element 37. One end of the elastic element 43 in the elastic force direction is connected to the rotating shaft of the limiting plate 42, and the other end of the elastic element 43 in the elastic force direction is connected to the rod surface of the force application rod 41. The elastic element 43 has the tendency to drive the end of the limiting plate 42 to rotate and embed itself in the direction close to the positioning groove 352.

[0045] Reference Figure 4 and Figure 6 When the inner liner 2 is disassembled, the locking rod 34 is driven by the force bar 41 to slide along the inner wall of the slide rail 311 towards the locking pin 31. The end of the locking rod 34 sequentially disengages from the limiting groove 14 and the clearance cavity 351 and is located in the slide rail 311. The end of the limiting plate 42 away from the force bar 41 faces the positioning groove 352. The elastic element 3 43 drives the limiting plate 42 to rotate towards the positioning groove 352. The end of the limiting plate 42 is embedded in the positioning groove 352. The surface of the limiting plate 42 abuts against the inner wall of the positioning groove 352 and limits the locking rod 34. As the inner liner 2 is removed, the limiting effect of the abutment plate on the sliding ring 35 disappears. The elastic element 37 drives the sliding ring 35 to slide away from the inner liner 2 along the axis of the locking pin 31. The inner wall of the positioning groove 352 abuts against the surface of the limiting plate 42 and guides the limiting plate 42 to disengage from the positioning groove 352. The limiting effect of the limiting plate 42 on the force rod 41 disappears, and the inner wall of the sliding ring 35 abuts against the roller surface of the roller part 342 and limits the locking rod 34 to the slide rail 311, thereby achieving the limiting stability of the locking rod 34 in the slide rail 311.

[0046] Reference Figure 4 and Figure 6The slider 44 is connected to the inner wall of the sliding ring 35. The side wall of the locking pin 31 has a groove 313 for the slider 44 to slide. The sliding direction of the slider 44 is parallel to the axis of the locking pin 31. The surface of the slider 44 abuts against the inner wall of the groove 313 and limits the deflection of the sliding ring 35, thereby ensuring the stability of the orientation of the positioning groove 352.

[0047] The implementation principle of the assembly and positioning structure of an integrated outer frame and a split inner liner in this application embodiment is as follows: When the inner liner plate 2 is embedded in the assembly cavity 11 and the end of the locking pin 31 is embedded in the locking hole 13, the locking cavity 12 is connected to the threaded hole 22, and the rod part 341 of the locking bolt 32 passes through the locking cavity 12 and is threaded and fixed to the inner wall of the threaded hole 22, so as to realize the detachable installation between the inner liner plate 2 and the frame 1. The locking pin 31 and the locking bolt 32 are located on both sides of the thickness direction of the inner liner plate 2, so that the inner liner plate 2 forms a bidirectional clamp in the thickness direction, avoiding the loosening and displacement of the locking bolt 32 caused by the misalignment of the inner liner plate 2 on the inner wall of the assembly cavity 11, and ensuring that the battery cell tray can maintain the accuracy and stability of the battery cell in the assembly gap 21 during long-term use.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
