[0031] The following will describe in detail a specific embodiment of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the description of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, unless otherwise clearly specified and limited, the terms "set", "install", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.

They are only for the convenience of description and simplified 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 should not be understood as a limitation on the utility model.

[0034] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0035] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0036] See also Figure 1 As shown, the embodiment of the first aspect of the utility model provides a vehicle battery pack transport device for the transportation of vehicle battery packs, including a drive assembly 1, a conveying assembly 2 for transporting the battery packs connected to the drive assembly 1, a support assembly 3 for installing the drive assembly 1 and the conveying assembly 2, and a guide assembly 4 fixedly connected to the support assembly 3 for guiding the battery pack to be transported along a preset direction. In this way, when the battery pack of the vehicle battery exchange system has thermal runaway, the vehicle battery pack transport device can quickly transport the battery pack that releases heat to a fire water tank for cooling and extinguishing the fire, so as to isolate it from the other battery packs in the first time to ensure safety.

[0037] See also Figure 2 As shown, overall, the support assembly 3 is a frame structure, including a first support beam 31, a second support beam 32 connected to the first support beam 31, and a third support beam 33 connected to the second support beam 32, wherein the first support beam 31, the second support beam 32, and the third support beam 33 are all in the shape of long strips, and the length directions are perpendicular to each other. In some embodiments, the number of the first support beam 31, the second support beam 32, and the third support beam 33 are all multiple. In this embodiment, the number of the first support beam 31 is four, the number of the second support beam 32 is eight, and the number of the third support beam 33 is two.

[0038] See also Figure 3 As shown, the driving assembly 1 includes a driving member 11 and a connecting plate 12 fixedly connected to the driving member 11, and the driving member 11 is fixedly connected to one side of the third supporting beam 33 through the connecting plate 12. It should be noted that the driving member 11 mentioned here may refer to a motor or other servo mechanism.

[0039] In some embodiments, the transmission method can be gear pair transmission, belt transmission or chain transmission. In this embodiment, since the battery pack for the vehicle has a certain weight and the battery pack will release heat when thermal runaway occurs, in order to ensure that the conveying component 2 can operate smoothly in a high temperature environment, the selected transmission method is chain transmission. Figure 3 As shown, the conveying assembly 2 includes a first transmission member 21 meshed with the driving member 11, a second transmission member 22 embedded in one end of the first support beam 31 and meshed with the first transmission member 21, a third transmission member 23 installed at the end of the second transmission member 22 and meshed with the second transmission member 22, and a fourth transmission member 24 embedded in the other end of the first support beam 31 and meshed with the third transmission member 23.

[0040] Please also refer to Figure 4 The second transmission member 22 includes a first transmission shaft 221, a first sprocket 222 meshing with the first transmission member 21, and a second sprocket 223 meshing with the third transmission member 23, wherein the first sprocket 222 and the second sprocket 223 are both mounted on the outer surface of the first transmission shaft 221. The fourth transmission member 24 includes a second transmission shaft 241, and a third sprocket 242 mounted on the outer surface of the second transmission shaft 241 and meshing with the third transmission member 23. It should be noted that the first transmission member 21 and the third transmission member 23 mentioned here can both refer to chains. Preferably, the third transmission member 23 refers to a double-row chain and the outer surface of the chain is coated with a high-temperature resistant insulation layer, which is not only beneficial for bearing the weight of the battery pack itself, but also can ensure that the vehicle battery pack transportation device can operate stably in a high-temperature environment.

[0041] In this way, when the driving member 11 rotates, the first transmission member 21 rotates synchronously under the driving action of the driving member 11, and at the same time drives the first sprocket 222 on the first transmission shaft 221 to rotate in linkage. Since the first transmission shaft 221, the first sprocket 222 and the second sprocket 223 are coaxially connected, at this time, one end of the third transmission member 23 rotates under the driving action of the second sprocket 223, and the other end drives the third sprocket 242 on the second transmission shaft 241 to rotate synchronously, thereby providing the battery pack placed on the third transmission member 23 with the required transportation power.

[0042] In some embodiments, in order to prevent the battery pack from slipping during transportation on the third transmission member 23, the outer surface of the third transmission member 23 may also be coated with an anti-slip layer to increase the friction between the contact surface of the third transmission member 23 and the battery pack.

[0043] To prevent the battery pack from falling or falling off during transportation, causing delayed delivery, please refer to Figure 5 As shown, the guide assembly 4 includes a guide wheel 41, a guide wheel bracket 42 rotatably connected to the guide wheel 41, and a guide wheel support plate 43 fixedly connected to one side of the first support beam 31 and fixedly connected to the guide wheel bracket 42. It should be noted that there are multiple guide wheels 41, and the multiple guide wheels 41 are arranged along a direction parallel to the length direction of the guide wheel bracket 42. In this way, when the battery pack is transported along the length direction of the first support beam 31 or the length direction of the third transmission member 23, the guide wheel 41 can not only prevent the battery pack from falling, but also help guide the battery pack to maintain the initial conveying direction because the outer surface of the guide wheel 41 and the outer surface of the battery pack are in rolling friction.

[0044] In some embodiments, the number of the guide components 4 may be multiple. In this embodiment, the number of the guide components 5 is twelve.

[0045] In this embodiment, in order to ensure the stable operation of the vehicle battery pack transport device, the vehicle battery pack transport device further includes an adjustment component 5 connected to the support component 3, see Figure 6 As shown, it includes a base 51, a fastener 52, and an adjusting member 53 connected between the base 51 and the fastener 52. By tightening or loosening the adjusting member 53 and cooperating with the fastener 52, the height of the support assembly 3 in a direction perpendicular to the ground can be adjusted to ensure the levelness of the vehicle battery pack transport device.

[0046] In some implementations, the number of the adjustment components 5 may be multiple. In this embodiment, the number of the adjustment components 5 is eight.

[0047] In some embodiments, in order to ensure that the vehicle battery pack transport device can transport the battery pack to a designated location or area, the vehicle battery pack transport device also includes a photoelectric switch (not shown in the figure) electrically connected to the drive assembly 1, and the photoelectric switch is fixedly connected to both sides of the first support beam 31 to provide a feedback signal to the drive assembly 1 and ensure that the battery pack stays at a preset location or area.

[0048] The embodiment of the second aspect of the utility model provides a vehicle battery exchange system, including a vehicle battery pack, a fire water tank and a vehicle battery pack transportation device as described in the above embodiment. When the battery pack has thermal runaway, the vehicle battery pack transportation device is used to transfer the battery pack with thermal runaway to the fire water tank, so that the above vehicle battery exchange system has a high fire safety index. It should be noted that the fire water tank mentioned here can refer to a box-type structure made of a material with high explosion-proof performance to ensure the safety of the vehicle battery exchange system.
