DETAILED DESCRIPTION

[0032] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] Please refer to Figures 1 to 10, a pallet structure for transporting battery modules (not shown in the figure), specifically, the pallet structure includes a bottom plate 1, a length check piece 3 and a width clamping piece 2, wherein: the bottom plate 1 has a working surface 11; the length check piece 3 is arranged on the working surface 11, the length check piece 3 includes a static portion 32 and a dynamic portion 31, the static portion 32 can approach or move away from the static portion 32 in a first direction X; the width clamping piece 2 is arranged on the working surface 11, there are two width clamping pieces 2, the length check piece 3 is located between the two width clamping pieces 2, the two width clamping pieces 2 can approach or move away from each other along a second direction Y; the first direction X is not parallel to the second direction Y; the dynamic portion 31, the static portion 32 and the two width clamping pieces 2 are jointly limited to form a clamping space. Figures 1 to 3 As shown, preferably, the two width clamps 2 are symmetrically arranged about the length check member 3 in the second direction Y. Optionally, the two width clamps 2 move synchronously. When in use, the battery module is placed on the length check member 3, and the dynamic part 31 cooperates with the static part 32 to limit the battery module in the first direction X. The two width clamps 2 cooperate to limit the battery module in the second direction Y. Since the distance between the two width clamps 2 and the distance between the dynamic part 31 and the static part 32 are adjustable, that is, the size of the clamping space is adjustable, the tray structure can adapt to battery modules of different specifications, has a simple structure, can adapt to battery module changes, and is easy to adjust.

[0036] In this embodiment, the two width clamping members 2 are symmetrically arranged with respect to the length check member 3, and the two width clamping members 2 move synchronously, which is beneficial to centering and fixing the battery module.

[0037] Preferably, the first direction X is perpendicular to the second direction Y. Figure 2 As shown, the first direction X and the second direction Y are both parallel to the working surface 11, and the first direction X and the second direction Y are perpendicular to each other, which can help to fully fix the battery module in a plane parallel to the working surface 11, and help to improve the stability of the battery module during transportation.

[0038] The length check member 3 also includes a support beam 33, which is extended along the first direction X, and the static portion 32 is arranged near one end of the support beam 33; the dynamic portion 31 is slidably connected to the support beam 33. The dynamic portion 31 slidably connected to the support beam 33 cooperates with the static portion 32 to realize stepless adjustment of the clamping space in the first direction X, so that even when clamping the same type of battery modules, it can avoid the situation that the battery module is falsely clamped (the size of the battery module is smaller than the distance between the dynamic portion 31 and the static portion 32) or over-clamped (the size of the battery module is larger than the distance between the dynamic portion 31 and the static portion 32) due to the size error of the battery module in the first direction X caused by manufacturing error or assembly factors. In other words, the length check member 3 here can adapt to the clamping and fixing of battery modules of different models and battery modules of the same model but with certain manufacturing errors.

[0039] Further, the length check member 3 also includes a first reset member 34, which acts on the dynamic part 31 so that the dynamic part 31 has a movement tendency to approach the static part 32 along the first direction X. The first reset member 34 here provides power for the dynamic part 31. Optionally, the first reset member 34 can be an electric push rod. Preferably, the first reset member 34 is a spring. The use of a spring for the first reset member 34 can greatly save costs.

[0040] like Figure 7 and Figure 8 As shown, the dynamic part 31 includes an integrated beam 311 slidably connected to the support beam 33, and the integrated beam 311 is extended along the first direction X; a plurality of limiting parts 312 are arranged at intervals along the extension direction of the integrated beam 311 on the integrated beam 311, and the limiting part 312 includes a stopper 3122, and the stopper 3122 is adjustable in the longitudinal direction. Here, the plurality of limiting parts 312 are suitable for different types of battery modules to adapt to the battery module replacement of a larger size range; at the same time, through the sliding connection between the integrated beam 311 and the support beam 33, a specific limiting part 312 can be fine-tuned along the first direction X when in use, so that when the first reset member 34 is used, the use of the plurality of limiting parts 312 can reduce the working stroke of the first reset member 34 in the first direction X, that is, reduce the sliding distance of the integrated beam 311 relative to the support beam 33 in the first direction X, thereby helping to reduce the length of the check member 3, that is, the size of the tray structure in the first direction X, saving working space, and improving the clamping efficiency of the battery module.

[0041] It should be noted that the height of the block 3122 in the longitudinal direction is adjustable. When in use, after determining the specific limiting portion 312 according to the specific model of the battery module, the block 3122 of all limiting portions 312 between the limiting portion 312 and the static portion 32 can be adjusted in height to avoid interfering with the battery module in the longitudinal direction.

[0042] Furthermore, the limiting portion 312 includes a mounting seat 3121, which is mounted on the integrated beam 311; a stopper 3122 is slidably connected to the mounting seat 3121, and a second reset member 3124 is provided on the mounting seat 3121, and the second reset member 3124 acts on the stopper 3122 so that the stopper 3122 has a tendency to move upward in the longitudinal direction. Optionally, the second reset member 3124 is a spring. Specifically, as Figure 8 and Fig. 9 As shown, the mounting seat 3121 is provided with a guide hole 3125, and the stopper 3122 is slidably embedded in the guide hole 3125; a cover plate 3123 is provided on the side of the mounting seat 3121 close to the integrated beam 311, and the cover plate 3123 is used to block the guide hole 3125, and the second reset member 3124 is located between the cover plate 3123 and the stopper 3122. Fig. 9 In the illustrated embodiment, when the stopper 3122 is subjected to downward pressure in the longitudinal direction, the second reset member 3124 acts on the stopper 3122 to make it move upward in the longitudinal direction. This arrangement facilitates the longitudinal height adjustment of the stopper 3122 during use (after the pressure of the battery module on the stopper 3122 is applied, the stopper 3122 can move downward in the longitudinal direction to avoid interfering with the battery module), and is also conducive to the rapid reset of the stopper 3122.

[0043] like Figure 7 , 8 and Fig.10 As shown, the length check member 3 also includes a driving part 35 and at least two limit seats 36. The driving part 35 is located between two adjacent limit seats 36. The limit seats 36 are assembled to the support beam 33. A guide rod 341 is provided between two adjacent limit seats 36. The guide rod 341 is parallel to the first direction X. The driving part 35 is sleeved outside the guide rod 341 and is slidably connected thereto. The driving part 35 is fixedly connected to the integrated beam 311, and the first reset member 34 is provided between the driving part 35 and a limit seat 36. In this embodiment, the first reset member 34 is preferably a spring. When in use, the first reset member 34 is sleeved outside the guide rod 341. Specifically, Fig.10 As shown, when in use, the driving part 35 is first slid to the left along the axial direction of the guide rod 341, that is, the first direction X. At this time, the integrated beam 311 and the driving part 35 move to the left synchronously, and the first reset member 34 is compressed. After the battery module is placed on the length check member 3, the driving part 35 is released, and the first reset member 34 drives the driving part 35 to make the integrated beam 311 move to the right along the first direction X. At this time, the limiting part 312 is pressed against the battery module to cooperate with the static part 32 to realize the clamping and fixation of the battery module in the first direction X.

[0044] In this embodiment, the support beam 33 is provided with an assembly groove 331, and a first slide rail 38 is provided at the bottom of the assembly groove 331. The first slide rail 38 extends along the first direction X, and a first slider 381 adapted to the first slide rail 38 is provided on the integrated beam 311. A strip hole 332 is provided through the bottom of the assembly groove 331, and the driving part 35 partially extends into the assembly groove 331 through the strip hole 332 and is connected to the integrated beam 311. Figure 6 As shown, the strip hole 332 is a square hole, and its length direction is parallel to the first direction X. The strip hole 332 here is used to limit the driving part 35 to prevent it from rotating around the guide rod 341 in the circumferential direction during movement along the first direction X, which is conducive to improving structural stability.

[0045] Furthermore, a first pad 37 is provided on the support beam 33, and in the longitudinal direction, the height of the mounting seat 3121 is not higher than the height of the first pad 37. The first pad 37 is used to support the battery module in the longitudinal direction.

[0046] In this embodiment, the length check member 3 further includes a limit plate 39, a limit groove is provided on the limit plate 39, the first pad 37 is installed on the support beam 33 through the limit plate 39, and the limit portion 312 is in the limit groove. The limit groove here extends along the first direction X. The limit groove can play a role in straightening the limit portion 312 to ensure that it does not tilt during the process of supporting the battery module.

[0047] In this embodiment, in order to achieve the synchronous movement of the two width clamping members 2, as shown in FIG. Figure 4 and Figure 5 As shown, a linkage gear 26 and two racks 25 are provided on the working surface 11, the racks 25 extend along the second direction Y and are slidably connected to the working surface 11, the racks 25 can slide relative to the working surface 11 along the second direction Y, the linkage gear 26 is between the two racks 25 and meshes with the racks 25, the two width clamping members 2 correspond to the two racks 25 one by one, and the width clamping members 2 are fixedly connected to the corresponding racks 25. When in use, the two racks 25 are linked by the linkage gear 26 to achieve synchronous movement of the two, thereby achieving synchronous approach or separation of the two width clamping members 2.

[0048] A third reset member 24 is provided on the working surface 11, and the third reset member 24 acts on the rack 25 or the width clamping member 2, so that the two width clamping members 2 have a movement tendency to approach each other. Optionally, the third reset member 24 is a spring, preferably a nitrogen spring. Specifically, a fixing seat 28 is provided on the working surface 11, and one end of the third reset member 24 is fixed to the rack 25, and the other end is fixed to the bottom plate 1. Figure 5As shown, the third reset member 24 is in a stretched state, and the tray structure is in an open state. After the battery module is placed between the two width clamping members 2, after the external force applied to the width clamping members 2 is removed, the two width clamping members 2 are moved closer to each other under the action of the third reset member 24 to clamp and fix the battery module in the second direction Y. This arrangement simplifies the component structure of the tray structure, saves production costs, and cooperates with the first reset member 34 to achieve unpowered clamping and fixing of the battery module.

[0049] Optionally, a second slide rail 27 is provided on the working surface 11, and the second slide rail 27 extends along the second direction Y. A second slider (not shown in the figure) adapted to the second slide rail 27 is provided on the rack 25 to realize the sliding action of the rack 25 relative to the working surface 11.

[0050] like Figure 4 and Figure 5 As shown, in this embodiment, the width clamping member 2 includes a mounting plate 21, a third slide rail 201 is arranged on the working surface 11, the third slide rail 201 is extended along the second direction Y, a third slider 202 adapted to the third slide rail 201 is arranged on the mounting plate 21, and the rack 25 is fixedly connected to the mounting plate 21;

[0051] The mounting plate 21 is provided with a second pad 22 and a pressure block 23. In the longitudinal direction, the pressure block 23 is higher than the second pad 22. The second pad 22 cooperates with the first pad 37 to support the battery module. The pressure block 23 is used to limit the battery module in the second direction Y. In this embodiment, there are multiple pressure blocks 23. The structural design of multiple pressure blocks 23 integrated on the mounting plate 21 can realize the synchronous clamping and fixing of various parts of the battery module in the first direction X in the second direction Y, improves work efficiency, and is conducive to the rapid adjustment of the tray structure after the battery module is changed, which is conducive to improving work efficiency.

[0052] This embodiment also provides a battery transport mechanism, including a frame, a transmission component and the aforementioned tray structure, wherein the transmission component is assembled on the frame and used to transport the tray structure. The transmission component here can be a conveyor belt or an assembly line, etc. Based on the advantage of the tray structure in improving work efficiency, the battery transport mechanism can also improve work efficiency.
