[0031] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 As shown, combined Figure 2-4 The utility model discloses a square lithium battery module tray, comprising a sliding seat 1, an adjusting component 3 and a limiting component 4.

[0033] The top of the sliding seat 1 is fixedly connected with a battery tray 2, and the battery tray 2 is used to position the square battery module. In this embodiment, the bottom of the sliding seat 1 is slidably connected with a guide rail 9, which is the guide rail 9 on the production line. The sliding seat 1 can move between different stations along the guide rail 9, which helps to quickly adjust the position of the battery module in different processing steps.

[0034] The adjustment component 3 is used to horizontally position the battery module, and includes an electric slide 31, a limit plate 32 and a fixed plate 33. The electric slide 31 is arranged inside the battery tray 2 and is used to horizontally adjust the distance between the limit plate 32 and the fixed plate 33. By adjusting the distance between the limit plate 32 and the fixed plate 33, it is possible to adapt to lithium battery modules of different sizes.

[0035] The limiting plate 32 and the fixing plate 33 are respectively arranged vertically and in parallel. By adjusting the distance between them through the electric slide 31, the fixed position of the module can be effectively controlled, thereby positioning the battery module in the horizontal direction.

[0036] The limit assembly 4 is used to limit the battery module in the height direction. Specifically, the limit assembly 4 includes a fixed box 41, a limit rod 42, a servo motor 43, a driving gear 44 and a transmission rack 45. The fixed box 41 is fixedly arranged on the top of the fixed plate 33. The limit rod 42 horizontally passes through the fixed box 41 and can move toward the limit plate 32. The transmission rack 45 is horizontally fixedly arranged on the top surface of the limit rod 42. The servo motor 43 is fixedly arranged on the outside of the fixed box 41. The output shaft of the servo motor 43 is meshed and connected with the transmission rack 45 through the driving gear 44.

[0037] The servo motor 43 is meshed with the transmission rack 45 through the driving gear 44, driving the horizontal movement of the limit rod 42, so that the limit rod 42 extends horizontally above the battery tray 2 to limit the movement of the battery module in the height direction of the battery tray 2. This structural setting effectively prevents the battery module from jumping in the vertical direction, especially during the transportation process of the production line, which can ensure the stability of the battery module and reduce potential damage caused by vibration or movement.

[0038] The square lithium battery module tray disclosed by the utility model can limit the position of the battery module in the horizontal direction through the adjustment component 3, and can limit the position of the battery module in the height direction through the limit component 4, thereby ensuring the precise positioning and safety of the battery module in different directions during production and transportation, and improving the overall production efficiency.

[0039] In order to ensure accurate positioning of the battery module in the height direction, the adjustment component 3 of the present embodiment also includes an extension plate 34 and a micro air pump 35. The extension plate 34 is vertically slidably connected inside the limit plate 32 and the fixed plate 33. The micro air pump 35 is fixedly connected inside the limit plate 32 and the fixed plate 33 and below the extension plate 34. The micro air pump 35 is used to drive the extension plate 34 to move upward relative to the limit plate 32 and the fixed plate 33. The limit component 4 is arranged on the top surface of the extension plate 34 on the fixed plate 33.

[0040] By adding the extension plate 34 and the micro air pump 35, the internal structure of the limit plate 32 and the fixed plate 33 can realize the up and down sliding adjustment of the extension plate 34. The micro air pump 35 drives the vertical movement of the extension plate 34, providing a more precise positioning and adjustment capability for the battery module in the height direction, and further enhancing the clamping stability of the tray to the battery module.

[0041] The limit assembly 4 is arranged on the top surface of the extension plate 34, and the limit assembly 4 can be adjusted according to the height change of the battery module by moving the extension plate 34 up and down. This structural setting ensures that the limit rod 42 is more effective in the height direction, and further prevents the battery module from vertically displacing in the tray.

[0042] In addition, the introduction of the extension plate 34 not only increases the stability of the module, but also provides a larger limit range. The drive of the micro air pump 35 makes the adjustment process more stable and accurate, reduces the impact on the module during operation, and thus protects the safety of the battery module.

[0043] By adding the extension plate 34 and the micro air pump 35, the height adjustment of the tray can be made more flexible and precise, effectively enhancing the fixation and limiting effect of the battery module in the horizontal and vertical directions, and improving the stability and safety of the module during production and transportation. In addition, the buffering effect of the return spring 36 can reduce the direct impact of the extension plate 34 on the battery module when it moves up and down, especially when the tray moves at high speed or stops suddenly, which can effectively protect the module and avoid damage caused by severe vibration.

[0044] As some preferred embodiments, the limiting assembly 4 further includes a connecting sleeve 46, which is fixedly arranged on the top surface of the extension plate 34 on the limiting plate 32, and the opening direction of the connecting sleeve 46 corresponds to the limiting rod 42. Thus, when the limiting rod 42 extends parallel to the limiting plate 32, the limiting rod 42 can be accurately inserted into the connecting sleeve 46, and the limiting rod 42 is constrained in the height direction, so that the battery module can be accurately positioned in the height direction.

[0045] It is worth noting that after the battery module is placed in the electric tray, the micro air pump 35 is first used to drive the extension plate 34 to move up and down to make the upper end of the extension plate 34 flush with the top surface of the battery module. At this time, when the limit rod 42 is driven to extend horizontally, when the limit rod 42 is docked with the connecting sleeve 46, the top surface of the battery module can be blocked, thereby accurately positioning the battery module in the height direction, ensuring that the battery module is more firmly fixed in the tray.

[0046] Since the types of battery modules are different, the type of battery tray 2 needs to be adjusted according to the model. In order to facilitate the rapid removal or installation of the battery tray 2 on the sliding seat 1, a replacement component 5 is also provided in this embodiment.

[0047] Specifically, the replacement component 5 includes a sliding rod 51, a connecting pin 53 and an adjusting screw 54. The top surface of the sliding seat 1 is provided with at least one mounting groove 11 along the length direction of the electric slide 31. The connecting pin 53 is accommodated in the mounting groove 11 and is fixedly connected to the bottom surface of the battery tray 2. A sliding groove 12 parallel to the electric slide 31 is provided inside the sliding seat 1. The sliding groove 12 passes horizontally through the mounting groove 11. The sliding rod 51 is arranged in the sliding groove 12 and can move horizontally along the sliding groove 12. The sliding rod 51 is located at the mounting groove 11 and is provided with a through hole 511 for the connecting pin 53 to pass through. The connecting pin 53 is L-shaped. One end of the adjusting screw 54 is threadedly connected to the sliding seat 1, and the other end is rotatably connected to the end of the sliding rod 51.

[0048] In this embodiment, the connecting pin 53 is an L-shaped structure. Specifically, the connecting pin 53 includes a vertical section and a horizontal section. The upper end of the vertical section is fixedly connected to the bottom surface of the battery tray 2, and the horizontal section is vertically fixedly connected to the bottom end of the vertical section. In the initial state, the adjusting screw 54 is rotated to drive the sliding rod 51 to move horizontally in the sliding groove 12, so that the through hole 511 on the sliding rod 51 is aligned with the installation groove 11. At this time, the connecting pin 53 of the battery tray 2 is vertically inserted into the installation groove 11 and passes through the through hole 511. By rotating the adjusting screw 54 in the opposite direction, the sliding rod 51 moves in the sliding groove 12, so that the connecting pin 5 3 is in contact with the side wall of the through hole 511. At this time, the horizontal section of the connecting pin 53 is at the bottom surface of the sliding rod 51. The through hole 511 and the mounting groove 11 are staggered up and down. The sliding rod 51 can limit the connecting pin 53 from being disengaged from the mounting groove 11, so that the battery tray 2 can be quickly installed on the sliding seat 1. When the battery tray 2 needs to be removed, it is only necessary to rotate the adjusting screw 54 to move the sliding rod 51 horizontally. After ensuring that the through hole 511 and the mounting groove 11 are aligned, the connecting pin 53 can be quickly disengaged from the through hole 511 and the mounting groove 11, thereby realizing the rapid disassembly of the battery tray 2 and the sliding seat 1.

[0049] By designing the L-shaped connecting pin 53 and rotating the adjusting screw 54, the battery tray 2 can be quickly installed and removed from the sliding seat 1. The adjusting screw 54 drives the sliding rod 51 to move so that the through hole 511 and the mounting groove 11 are aligned or staggered, thereby inserting or releasing the connecting pin 53. This process is simple to operate, can significantly reduce the time required for tray replacement, and improve production efficiency.

[0050] As some preferred embodiments, the replacement component 5 also includes a connecting plate 52, and a limiting cavity 113 connected to the sliding groove 12 is arranged inside the end of the sliding seat 1 close to the adjusting screw 54, and the connecting plate 52 is slidably set in the limiting cavity 113, and the width of the limiting cavity 113 is adapted to the width of the through hole 511. One end of the adjusting screw 54 is threadedly connected to the sliding seat 1, and the other end extends into the limiting cavity 113 and is rotatably connected to the connecting plate 52, and the end of the sliding rod 51 is fixedly connected to the connecting plate 52.

[0051] With this arrangement, the movement stroke of the sliding rod 51 can be effectively controlled by the movement stroke of the connecting plate 52 in the limiting cavity 113. This design makes the alignment and staggering operation of the through hole 511 and the mounting groove 11 faster and more accurate. By adjusting the screw 54, the sliding rod 51 can move accurately within a limited range, quickly aligning the through hole 511 and the mounting groove 11, and ensuring the smooth insertion or release of the connecting pin 53. When staggering is required, the movement stroke of the connecting plate 52 can also quickly stagger the through hole 511 and the mounting groove 11 to prevent the connecting pin 53 from accidentally falling out, thereby improving the operating efficiency and the stability of the assembly.

[0052] In this embodiment, a controller 6 is installed on the front of the battery tray 2, and a battery 7 is fixedly connected to the bottom of the battery tray 2. The electric slide 31, the micro air pump 35, the servo motor 43, and the connection method between the battery 7 and the controller 6 are all electrically connected; the electric slide 31 can be started by the controller 6, and the electric slide 31 drives the limit plate 32 to move horizontally; the servo motor 43 is started by the controller 6, and the servo motor 43 drives the driving gear 44 to rotate; the micro air pump 35 is started by the controller 6, and the micro air pump 35 sends air into the fixed plate 33 and the limit plate 32, thereby driving the extension plate 34 to move upward.

[0053] In this embodiment, in order to protect the square lithium battery module, the outer walls of the limiting plate 32, the fixing plate 33 and the extension plate 34 are fixedly connected with a protection pad 8, which abuts against the outside of the square lithium battery module and can provide protection for the outside of the square lithium battery module.

[0054] The working principle of the utility model is:

[0055] The square lithium battery module is placed in the battery tray 2 so that the square lithium battery module is close to the outer wall of the fixing plate 33. The controller 6 starts the electric slide 31, and the electric slide 31 drives the limit plate 32 to move toward the fixing plate 33, so as to cooperate with the fixing plate 33 to clamp the battery module horizontally. The controller 6 starts the micro air pump 35, and the micro air pump 35 sends air into the fixing plate 33 and the limit plate 32. The air entering the fixing plate 33 and the limit plate 32 will push the extension plate 34 to move upward. When the height of the extension plate 34 exceeds After passing the top surface of the square lithium battery module, the micro air pump 35 no longer sends air into the fixing plate 33 and the limiting plate 32, and the extension plate 34 no longer moves upward. The controller 6 starts the servo motor 43, and the servo motor 43 drives the driving gear 44 to rotate. The driving gear 44 pushes the limiting rod 42 to move toward the limiting plate 32 through the transmission rack 45 and inserts into the connecting sleeve 46. The fixing plate 33 and the limiting plate 32 will limit the square lithium battery module in the horizontal direction, and the limiting rod 42 will limit the square lithium battery module in the vertical direction;

[0056] When the battery tray 2 needs to be replaced, the adjusting screw 54 is screwed, and the adjusting screw 54 will drive the sliding rod 51 to move horizontally through the connecting plate 52. When the through hole 511 on the sliding rod 51 is aligned with the mounting groove 11, the battery tray 2 is pulled, and the battery tray 2 drives the connecting pin 53 to disengage from the sliding seat 1, and the new battery tray 2 is replaced on the top of the sliding seat 1. The connecting pin 53 at the bottom of the battery tray 2 is inserted into the mounting groove 11 and passes through the through hole 511. The adjusting screw 54 is rotated in the opposite direction, and the adjusting screw 54 drives the sliding rod 51 to move in the opposite direction through the connecting plate 52. At this time, the through hole 511 is offset from the mounting groove 11. At this time, the sliding rod 51 will re-engage the connecting pin 53, thereby fixing the battery tray 2 on the top of the sliding seat 1.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
