[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Reference below Figure 1 and Figure 2 A battery pack conveying line 100 according to an embodiment of the present invention is described.

[0025] like Figure 1 and Figure 2 As shown, the battery pack conveyor line 100 according to an embodiment of the utility model includes: a guide rail 10 and a battery support 20.

[0026] Specifically, a guide groove 11 extending along the length direction of the guide rail 10 is formed on the guide rail 10, and the battery support 20 is arranged on the guide rail 10 for supporting the battery pack. The battery support 20 is provided with at least one limiting protrusion 21 for limiting the battery pack. For example, the limiting protrusion 21 can be one, two or four. The battery support 20 is also provided with a roller 22, which can be rotatably engaged in the guide groove 11 so that the battery support 20 can slide along the guide rail 10.

[0027] During the operation of the battery pack conveyor line 100, the battery pack is first placed on the battery holder 20 and the battery pack is limitedly engaged with the limiting protrusion 21. Then the roller 22 rolls in the guide groove 11 so that the battery holder 20 can slide on the guide rail 10 with the battery pack. When the sensor recognizes that the battery pack has reached the specified position, the battery pack conveyor line 100 stops moving the battery holder 20 and then performs a battery replacement operation on the battery pack.

[0028] In this embodiment, the limiting protrusion 21 can position the battery pack, so that the battery pack can be quickly placed in place on the battery support 20 when the battery pack is placed. During the movement of the battery support 20, when the battery pack is displaced relative to the battery support 20, the limiting protrusion 21 can limit the battery pack, thereby preventing the battery pack from shifting on the battery support 20.

[0029] The guide groove 11 can limit the roller 22, so that the sliding path of the battery holder 20 on the guide rail 10 is more precise, and the guide groove 11 can position the roller 22, so that the battery holder 20 can be quickly assembled on the guide rail 10. It can be understood that there is a lot of dust and other impurities on the replaced battery pack, and some dust and other impurities will fall into the guide groove 11, and there is less external obstruction of the battery swap station, and rain and snow may fall into the guide groove 11. By rolling the roller 22 in the guide groove 11, the roller 22 can more easily run over dust and other impurities, thereby improving the reliability of the battery pack conveyor line 100 during operation.

[0030] In addition, the roller 22 rolling in the guide groove 11 has lower requirements for assembly accuracy, which can reduce the difficulty of assembly. The roller 22 is also easier to maintain and requires less maintenance, which can improve the user experience.

[0031] According to the battery pack conveyor line 100 of the embodiment of the utility model, on the one hand, by providing a limiting protrusion 21 on the battery support 20, the probability of the battery pack being offset relative to the battery support 20 during transportation can be reduced, so that the battery pack positioning can be more accurate, thereby improving the battery replacement efficiency. On the other hand, the battery support 20 moves on the guide rail 10 through the roller 22, and the rolling of the roller 22 is less affected by foreign matter such as dust in the guide groove 11, which can improve the reliability of the battery pack conveyor line 100 during operation.

[0032] In some embodiments of the present invention, the diameter of the roller 22 is 50 mm-100 mm. For example, the diameter of the roller 22 can be 50 mm, 52 mm, 53 mm, 57 mm, 64 mm, 72 mm, 88 mm, 93 mm or 100 mm, so that the size of the roller 22 can meet the use requirements.

[0033] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the guide groove 11 is formed on one side of the guide rail 10 in the horizontal direction, and the opening of the guide groove 11 faces the horizontal direction, and the roller 22 rolls with at least one side wall of the guide groove 11 in the vertical direction. In this way, the side wall of the guide groove 11 in the vertical direction can prevent the roller 22 from escaping from the guide groove 11, thereby improving the reliability of the connection between the battery holder 20 and the guide rail 10, and in the process of the battery holder 20 moving, the guide groove 11 can limit the displacement of the roller 22 in the vertical direction, thereby reducing the vibration amplitude of the battery holder 20 in the vertical direction, and further reducing the probability of the battery pack being offset on the battery holder 20.

[0034] Among them, preferably, the sum of the gaps between the roller 22 and the upper and lower side walls of the guide groove 11 is 0.1mm-0.2mm. For example, the sum of the gaps between the roller 22 and the upper and lower side walls of the guide groove 11 can be 0.11mm, 0.13mm, 0.17mm or 0.2mm, thereby ensuring that the vibration amplitude of the battery holder 20 in the up and down directions meets the use requirements.

[0035] In some embodiments of the present invention, Figure 2 As shown, a connecting plate portion 221 extending downward is provided at the lower side of the battery holder 20, and a supporting shaft 223 of the roller 22 is connected to the connecting plate portion 221. The connecting plate portion 221 is provided on one side of the guide rail 10 where the guide groove 11 is provided, thereby enabling the roller 22 of the battery holder 20 to be arranged on the guide rail 10. During the product design process, the size of the connecting plate portion 221 can be adjusted to meet more product design requirements.

[0036] In some embodiments of the present invention, Figure 1 As shown, the number of guide rails 10 is at least one, for example, the guide rails 10 may be one, two, three or four. When the number of guide rails 10 is multiple, the multiple guide rails 10 are arranged in parallel, and the battery holder 20 includes multiple support seats 23, and the support seats 23 correspond to the guide rails 10 one by one. The multiple support seats 23 are provided with rollers 22 and limiting protrusions 21. The support seats 23 cooperate with the guide rails 10 through the rollers 22, and the multiple support seats 23 cooperate with each other to support the battery pack together. When the battery pack is conveyed, the battery pack is placed on the multiple support seats 23. In this way, the multiple support seats 23 provide support at multiple positions of the battery pack, so that the battery pack can be stably supported on the battery holder 20, and no materials are needed between the multiple support seats 23, so that the materials used by the battery holder 20 can be saved. On the one hand, the production cost of the battery pack conveyor line 100 can be reduced, and on the other hand, the driving force required to drive the battery holder 20 to move can be reduced.

[0037] In some embodiments of the utility model, in the vertical direction of the guide rail 10, a support link is connected between two adjacent support seats 23. By setting the support link, the structural stability and structural strength of the battery holder 20 can be improved, and the support link can make the support seats 23 move synchronously, thereby improving the stability of the battery holder 20 during movement.

[0038] In some embodiments of the utility model, guide grooves 11 are formed on both sides of the guide rail 10 in the horizontal direction, and two rows of roller groups 22 corresponding to the guide grooves 11 are provided on the support seat 23. The roller group 22 includes at least one roller 22. For example, the roller group 22 may include one, two or three rollers 22. The rollers 22 in the two rows of roller groups 22 are respectively matched in the two guide grooves 11 of the guide rail 10. As a result, the stability of the support seat 23 moving on the guide rail 10 can be improved, thereby further improving the stability of the battery holder 20 moving on the guide rail 10.

[0039] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the support seat 23 includes a support plate 231, and the support plate 231 is provided with limiting protrusions 21 at both ends in the length direction, and the limiting protrusions 21 are suitable for being arranged on opposite sides of the battery pack. In this way, when the battery pack is placed on multiple support seats 23, there are multiple limiting protrusions 21 on one side of the moving direction of the battery pack to limit the battery pack, thereby further reducing the probability of the battery pack being offset on the battery support 20. In the process of product design, the support plate 231 on the support seat 23 can be replaced so that the support plate 231 can adapt to more battery pack models, thereby improving the adaptability of the battery pack conveyor line 100.

[0040] In some embodiments of the present invention, Figure 1 As shown, the battery pack conveyor line 100 also includes: a driving mechanism, the driving mechanism includes: a transmission structure and a driving motor 33, specifically, the transmission structure includes a tensioning wheel 31 and a conveyor belt 32, the number of the tensioning wheels 31 is multiple, for example, the tensioning wheels 31 can be two, three or four, at least two of the multiple tensioning wheels 31 are respectively arranged on both sides of the guide rail 10 in the length direction, the conveyor belt 32 is tensioned between the multiple tensioning wheels 31, the battery support 20 is fixedly connected to the conveyor belt 32, and the driving motor 33 is connected to the tensioning wheel 31 to drive the conveyor belt 32 to move through the tensioning wheel 31.

[0041] Preferably, the driving motor 33 is a servo motor. During the operation of the battery pack conveyor line 100, the driving motor 33 drives the tension wheel 31 to rotate, the tension wheel 31 drives the conveyor belt 32 to move, and the conveyor belt 32 drives the battery holder 20 to move, so that the battery holder 20 can be moved on the guide rail 10. The conveyor belt 32 is easy to arrange, and the matching accuracy requirement of the conveyor belt 32 and the tension wheel 31 is relatively low, which can reduce the production difficulty of the battery pack conveyor line 100.

[0042] In some embodiments of the utility model, a fixed channel is formed on the battery support 20 and passes through the battery support 20 along the length direction of the guide rail 10, and the conveyor belt 32 is arranged in the fixed channel and is fixedly connected to the inner wall of the fixed channel. In this way, the connection area between the battery support 20 and the conveyor belt 32 can be increased, thereby improving the reliability of the connection between the conveyor belt 32 and the battery support 20, and the driving force of the conveyor belt 32 on the battery support 20 is more distributed, which can improve the stability of the movement of the battery support 20.

[0043] In some embodiments of the present invention, Figure 2 As shown, the battery holder 20 further includes: a bottom plate 24 and a pressing plate 25, the pressing plate 25 is connected to the lower side of the bottom plate 24, and the pressing plate 25 and the bottom plate 24 cooperate to define a fixed channel. In this way, during the production process, the structure of the battery holder 20 is simpler, which can reduce the production difficulty and production cost. During the assembly process, the assembly sequence of the bottom plate 24 and the pressing plate 25 can be adjusted according to the needs of the assembly environment, thereby reducing the assembly difficulty. During the product design process, the sizes of the bottom plate 24 and the pressing plate 25 can be adjusted to meet more product design needs.

[0044] In some embodiments of the present invention, Figure 2 As shown, the battery holder 20 also includes a mounting plate portion 222, which is a horizontal plate. One end of the mounting plate portion 222 is connected to the connecting plate portion 221, and the other end is connected to the bottom plate 24. The support plate 231 is supported on the bottom plate 24. Thus, the mounting plate portion 222 and the connecting plate portion 221 can form an "L" shape, so that the battery holder 20 can avoid the guide rail 10. In the process of product design, when it is necessary to transport battery packs of different models, the support plate 231 on the bottom plate 24 can be replaced so that the limiting protrusion 21 on the support plate 231 is adapted to the new battery pack, thereby meeting more transportation needs. Preferably, the bottom plate 24 is bolted to the mounting plate portion 222.

[0045] In some embodiments of the present invention, Figure 1As shown, there are two guide rails 10, which are arranged in parallel, there are two transmission structures, which correspond to the two guide rails 10, and the conveyor belt 32 is arranged above the corresponding guide rail 10. In this way, the two conveyor belts 32 can drive the battery holder 20 to move, so that the driving force on the battery holder 20 is more evenly distributed, and the stability of the battery holder 20 during movement is further improved. Preferably, the battery holder 20 includes two support seats 23, and the two support seats 23 are respectively connected to the two conveyor belts 32.

[0046] The driving mechanism also includes a driving shaft 34, which is disposed on one side of the guide rail 10 in the length direction, and the driving shaft 34 is connected to two tensioning wheels 31 located on the same side of the guide rail 10 in the length direction as the driving shaft 34, and a driving motor 33 is connected to the driving shaft 34 to drive the driving shaft 34 to rotate. Therefore, when the driving shaft 34 rotates, the two tensioning wheels 31 can rotate synchronously with the driving shaft 34, and the two conveyor belts 32 are driven by the two tensioning wheels 31 to rotate synchronously, and at the same time, a driving force is applied to the movement of the battery holder 20, so that the two conveyor belts 32 can drive the battery holder 20, and the stability of the battery holder 20 during the movement process can be ensured.

[0047] In some embodiments of the present invention, Figure 1 As shown, there are multiple battery holders 20, for example, there may be two, three or four battery holders 20, and the multiple battery holders 20 are arranged at intervals in the length direction of the guide rail 10. In this way, each battery holder 20 can be used for battery conveying, thereby improving the conveying efficiency of the battery pack conveying line 100. In the process of product design, the number of battery holders 20 on the battery pack conveying line 100 or the distance between the battery holders 20 can be increased to meet more conveying needs.
