[0032] Figure 1 This is a schematic diagram of the structure of a battery pack transport device 100 provided in an embodiment of this application, as shown below. Figure 1 As shown in the figure, this application provides a battery pack transport device 100, including a base frame 10, a guide mechanism 20, a drive mechanism 30, a transmission mechanism 40, and a support assembly 50. The details of each part are described below.

[0033] The base frame 10 serves as the mounting foundation for other mechanisms and components. As an example, such as... Figure 2 As shown, the bottom frame 10 is a rectangular frame structure, including two longitudinal beams 11 and multiple transverse beams 12. The two longitudinal beams 11 are parallel and each longitudinal beam 11 extends along a first direction. The multiple transverse beams 12 are arranged at intervals between the two longitudinal beams 11 along the first direction. Each transverse beam 12 extends along a second direction perpendicular to the first direction and its two ends are respectively connected to the two longitudinal beams 11.

[0034] The guide mechanism 20 is mounted on the base frame 10 to provide guidance and motion constraints for the movement of the supporting assembly 50. As an example, such as... Figure 2 As shown, the guide mechanism 20 includes two linear guide rails 21, which are respectively mounted on two longitudinal beams 11 of the base frame 10. Each linear guide rail 21 includes a guide rail 211 mounted along the longitudinal beam 11 and a plurality of sliders 212 mounted on the guide rail 211. These sliders 212 are connected to the support assembly 50. As shown in the figure, each guide rail 211 has three sliders 212.

[0035] Both the drive mechanism 30 and the transmission mechanism 40 are mounted on the base frame 10. The drive mechanism 30 is used to provide power, and the transmission mechanism 40 is used to transmit the power of the drive mechanism 30 to the slider 212 of the guide mechanism 20 to drive the support assembly 50 to move. Specifically, the output end of the drive mechanism 30 is connected to the input end of the transmission mechanism 40, and the output end of the transmission mechanism 40 is connected to the slider 212 of the guide mechanism 20 to drive the slider 212 to move along the guide rail 211.

[0036] As an example, Figure 3As shown, the drive mechanism 30 includes a geared motor 31, which is mounted on a crossbeam 12 of the base frame 10 via a motor mount (not shown in the figure); the transmission mechanism 40 includes a chain drive assembly 41, a drive shaft 42, and two belt drive assemblies 43. The chain drive assembly 41 includes a drive sprocket 411, a driven sprocket 412, and a chain 413. The drive sprocket 411 is coaxially connected to the output shaft of the geared motor 31, the driven sprocket 412 is coaxially connected to the drive shaft 42, and the chain 413 is drively connected to the drive sprocket 411 and the driven sprocket 412. The drive shaft 42 is located at one end of the two linear guides 21 and extends along the second direction. The drive shaft 42 is mounted on a crossbeam 12 of the base frame 10 via multiple bearings 13. Two belt drive assemblies 43 are arranged corresponding to the two linear guides 21. Each belt drive assembly 43 includes a drive pulley 431, a driven pulley 432, and a synchronous belt 433. The drive pulley 431 is located at one end of the corresponding linear guide 21 and is coaxially connected to the end of the drive shaft 42. The driven pulley 432 is located at the other end of the corresponding linear guide 21 and is rotatably mounted on a pulley mounting seat 14 (see...) via a rotating shaft. Figure 2 On the bottom frame 10, the pulley mounting base 14 is connected to the corresponding longitudinal beam 11. The synchronous belt 433 is connected to the driving pulley 431, the driven pulley 432, and the corresponding sliders 212 of the linear guide rail 21 (fixed to the sliders 212 by fasteners). When the geared motor 31 is working, its output shaft drives the transmission shaft 42 to rotate through the chain transmission assembly 41. The transmission shaft 42 drives the two belt transmission assemblies 43 to drive synchronously, so that the sliders 212 of the two linear guide rails 21 move synchronously along their respective guide rails 211.

[0037] The support assembly 50 is mounted on the slider 212 of the two linear guide rails 21. The support assembly 50 is used to support the battery pack and its structural design is compatible with at least two different sizes of battery packs.

[0038] As an example, such as Figure 4 As shown, the support assembly 50 includes a base 51, multiple pillars 52, and two brackets 53.

[0039] The base 51 is mounted on the sliders 212 of the two linear guide rails 21. The base 51 includes two fixed base plates 511 and a fixed base plate connecting plate 512. The two fixed base plates 511 are respectively mounted on the sliders 212 of the two linear guide rails 21. Each fixed base plate 511 is an elongated structure and extends along a first direction. The fixed base plate connecting plate 512 is a C-shaped structure. The main body of the fixed base plate 511 extends along a second direction. Both ends of the fixed base plate 511 extend along the first direction and are respectively connected to the two fixed base plates 511.

[0040] Each fixed base plate 511 is equipped with a plurality of supports 52 spaced apart along a first direction. Each support 52 extends along a third direction perpendicular to the first and second directions. As shown in the figure, each fixed base plate 511 has two supports 52. These supports 52 raise the plane on which the bracket 53 is located (that is, the battery pack mounting surface) to prevent the bracket 53 from causing structural interference to other mechanisms.

[0041] Two brackets 53 are respectively arranged corresponding to two fixed base plates 511 (or two linear guide rails 21) and respectively mounted on the support columns 52 of the corresponding fixed base plates 511. Each bracket 53 is an elongated structure extending along a first direction. Each bracket 53 has multiple slots for accommodating the bottom edge of the battery pack. These slots extend along the first direction and are arranged in a stepped manner in a third direction, with different lengths (in the first direction) and depths (in the third direction) to accommodate battery packs of different sizes. As shown in the figure, each bracket 53 has two slots, namely a first slot 531 and a second slot 532, which can accommodate two sizes of battery packs. Specifically, as shown in the figure... Figure 5 and Figure 6 As shown, the first slot 531 on each bracket 53 is adapted to the smaller first battery pack 1, and the second slot 532 is adapted to the larger second battery pack 2.

[0042] The bracket 53 may also be equipped with a stop 533 to prevent the battery pack from falling off the bracket 53. The shape of each slot is designed according to the side profile of the battery pack it is adapted to, and can be rectangular, trapezoidal or other shapes. In the figure, two slots on one bracket 53 are rectangular, and two slots on another bracket 53 are trapezoidal, to adapt to a battery pack with a rectangular profile on one side and a trapezoidal profile on the other side.

[0043] The working principle of the battery pack transport device 100 is as follows: Figure 7 As shown, during operation, the battery pack is placed in the matching slots on the two brackets 53 of the support assembly 50. The power output by the geared motor 31 of the drive mechanism 30 is transmitted sequentially through the chain drive assembly 41, the drive shaft 42, and the two belt drive assemblies 43, causing the sliders 212 of the two linear guide rails 21 of the guide mechanism 20 to move along their respective guide rails 211, thereby driving the support assembly 50 and the battery pack to move together, realizing the transportation of the battery pack.

[0044] This application also provides a production line, which includes the battery pack transport device 100 described above.

[0045] This application embodiment also provides a battery swapping station, which includes the battery pack transport device 100 described above.

[0046] In summary, the battery pack transport device, production line, and battery swapping station provided in this application, by designing multiple trays arranged in a stepped manner on the bracket, can adapt to battery packs of different sizes, thereby improving the versatility and applicability of the battery pack transport device. In the application of the production line and battery swapping station, it can effectively improve equipment utilization and reduce equipment investment and operating costs.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
