[0086] Hereinafter, a specific embodiment of the present application will be described in more detail with reference to the accompanying drawings, which show a representative embodiment of the present application and are not limiting.

[0087] The present application provides a battery swap station. The battery swap station is used for a vehicle, and the vehicle (e.g., a truck) includes a battery device with low power.

[0088] Please refer to Figure 1 The battery swap station 100 includes a box body 111, a first moving device 120, a second moving device 130 and a battery swap device 150. The box body 111 stores a battery device with full power inside. The box body 111 has an entrance and exit 113 which communicates the outside and the inside of the box body 111. The first moving device 120 is movably connected to the box body 111 along a first horizontal direction. The second moving device 130 is arranged on the first moving device 120 and can move with the first moving device 120. The second moving device 130 is movably connected to the first moving device 120 along a second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. The battery swap device 150 is arranged on the second moving device 130 and can move with the second moving device 130. It should be noted that the battery swap device 150 can move to the outside of the box body 111 via the entrance and exit 113 and be located directly above the battery device with low power. The battery swap device 150 is used to remove the battery device with low power and place the battery device with full power to the vehicle.

[0089] According to the battery swap station 100 of the present application, the first moving device 120 and the second moving device 130 are used to drive the battery swap device 150 to move along the horizontal direction (the first horizontal direction and / or the second horizontal direction), which avoids the battery swap device 150 itself needing to be multi-stage telescopic along the horizontal direction, makes the structure of the battery swap device 150 simpler, the safety higher, the life longer, and effectively reduces the cost of the battery swap station 100.

[0090] Please continue to refer to Figure 1The box 111 can be configured as a container. The container has a mature production process, is easy to obtain, and has good structural strength, which is suitable for the arrangement of various components in the battery swap station 100. Preferably, the first horizontal direction is configured as the length direction DL of the container, and the second horizontal direction is configured as the width direction DW of the container. The battery swap station 100 further comprises a track 112 arranged along the first horizontal direction D1 and located inside the box 111. A first moving device 120 is movably connected to the track 112 along the first horizontal direction D1. Specifically, the track 112 is arranged in pairs, and the two tracks 112 arranged in pairs are spaced apart along the second horizontal direction. Further, the battery swap station 100 further comprises a supporting member 118 arranged along the first horizontal direction, which is arranged inside the box 111 and corresponds to the track 112. The supporting member 118 is located below the track 112 and abuts against the first moving device 120. In other words, the inside of the box 111 is provided with a support and guide structure suitable for the first moving device 120. It can be understood that the first moving device 120 cooperates with the track 112 and the supporting member 118 to improve the accuracy and smoothness of the movement of the first moving device 120 relative to the box 111.

[0091] The battery swap station 100 further comprises a support assembly 115 located outside the box 111, which is arranged at the bottom of the box 111 to support the box 111. Figure 1 Specifically, the support assembly 115 comprises a stand 116 and a footing 117. The stand 116 is arranged along the vertical direction DH and connected to the bottom of the box 111, and the footing 117 is connected to the end of the stand 116 away from the box 111.

[0092] In order to make the storage of the battery equipment inside the box 111 more organized, the inside of the box 111 is provided with a first storage position and a second storage position. The first storage position is used to store the fully charged battery equipment, and the second storage position is used to store the low battery equipment.

[0093] Please refer to Figures 2 to 4 Specifically, the first moving device 120 comprises a first longitudinal beam 121, a first transverse beam 122, a first driving member 123, a first transmission shaft 124, a first follower 125, a second follower 126, a third follower 127, and a walking wheel 128. The first longitudinal beam 121 is arranged along the first horizontal direction, and the first transverse beam 122 is arranged along the second horizontal direction. The first longitudinal beam 121 is arranged in pairs, and the two first longitudinal beams 121 arranged in pairs are spaced apart along the second horizontal direction. The first transverse beam 122 is arranged in pairs, and the two first transverse beams 122 arranged in pairs are spaced apart along the first horizontal direction. The two first longitudinal beams 121 and the two first transverse beams 122 form a substantially rectangular first frame structure. The first driving member 123 (for example, a motor) is arranged in the aforementioned first frame structure, and the first driving member 123 is connected with the first transmission shaft 124.Figure 3 In some embodiments, the first transmission shaft 124 is arranged along a second horizontal direction, and an end of the first transmission shaft 124 distal to the first driving member 123 is connected with a first follower 125. The first follower 125 is drivingly connected with at least two third followers 127 through a second follower 126. The first follower 125 and the second follower 126 are both pivotally connected to the first frame structure along an axis extending along the second horizontal direction. The walking wheels 128 are unpowered and are pivotally connected to the first frame structure along an axis extending along the second horizontal direction. For example, the first driving member 123 is configured as a double-shaft motor and is connected to the first transmission shaft 124. The first driving member 123 drives the first transmission shaft 124 to pivot along an axis of the first transmission shaft 124, thereby driving the first follower 125 to rotate. The first follower 125 and the third followers 127 are configured as sprockets, and the second follower 126 is configured as a chain. The first follower 125 will walk along the chain (or the second follower 126), thereby causing the walking wheels 128 to roll along the support member 118, and achieving the movement of the first moving device 120 along the first horizontal direction.

[0094] Please continue to refer to Figures 2 to 4The second moving device 130 comprises a second longitudinal beam 131, a second horizontal beam 132, a connecting member 133, a second driving member 134, a second transmission shaft 135, a first driven member 136, a second driven member 137 and a first tow chain 138. Specifically, the second longitudinal beam 131 is arranged along the first horizontal direction, and the second horizontal beam 132 is arranged along the second horizontal direction. The second longitudinal beam 131 is arranged in pairs, and the two second longitudinal beams 131 in each pair are spaced apart along the second horizontal direction. The second horizontal beam 132 is arranged in pairs, and the two second horizontal beams 132 in each pair are spaced apart along the first horizontal direction. The two second longitudinal beams 131 and the two second horizontal beams 132 enclose a substantially rectangular second frame structure. The connecting member 133 is connected to the first frame structure and the second frame structure, so that the second frame structure can move relative to the first frame structure along the second horizontal direction. The second driving member 134 (for example, a motor) is arranged in the aforementioned second frame structure. For example, the second driving member 134 is configured as a double-shaft motor and is connected to the second transmission shaft 135. The second transmission shaft 135 is arranged along the second horizontal direction. The second driving member 134 drives the second transmission shaft 135 to pivot about the axis of the second transmission shaft 135, thereby driving the driven member coaxially installed with the second transmission shaft 135 to rotate, and the second driven member 137 is drivingly connected with the first driven member 136. The driven member and the first driven member 136 can be configured as sprockets, and the second transmission member 137 is configured as a chain suitable for the sprockets and is connected to the first frame structure. The driven member and the first driven member 136 rotate along the second transmission member 137, thereby enabling the second moving device 130 to move relative to the first moving device 120 along the second horizontal direction. The first tow chain 138 is arranged in the second frame structure to guide the orderly movement of the second frame structure and ensure stable operation of the equipment.

[0095] The battery swap station 100 further comprises a third moving device 140 arranged in the second moving device 130 and capable of moving with the second moving device 130. The third moving device 140 is movably connected to the second moving device 130 along the first horizontal direction. The battery swap equipment 150 is connected to the third moving device 140 and capable of moving with the third moving device 140. Specifically, the third moving device 140 comprises a fixing member 141, a second tow chain 142, a third driving member 143, a third transmission member 144 and a fourth transmission member 145. Similar to the aforementioned walking structure, it can be generally summarized that the third driving member 143 is configured as a motor, and the motor drives the sprocket to rotate along the chain, thereby enabling the third moving device 140 to move relative to the second moving device 130 along the first horizontal direction. Details are not described here.

[0096] Further, the battery swapping device 150 further comprises a hoist and a lifting assembly. The hoist is movably connected to the second moving device in the vertical direction DH. The lifting assembly is arranged on the second moving device 130 and is capable of moving with the second moving device 130. The lifting assembly is connected to the hoist to drive the hoist to move in the vertical direction DH. Specifically, since the third moving device 140 is capable of moving relative to the second moving device 130 in the first horizontal direction, the position adjustment of the third moving device 140 mainly depends on the first moving device 120 and / or the second moving device 130. Therefore, the aforementioned hoist and lifting assembly can be arranged on the third moving device 140 and are capable of moving with the third moving device 140.

[0097] Based on the aforementioned battery swapping station 100, the present application further provides a battery swapping method suitable for the battery swapping station 100.

[0098] Please return to refer to Figure 1 It should be noted that the battery swapping station 100 further comprises a detection device 114 and a control device. The detection device 114 is arranged on the box body 111, and the detection device 114 is used to detect the position of the battery equipment with insufficient power at the vehicle. The control device is arranged on the box body 111, and the control device is used to receive the detection signal of the detection device 114 to adjust the position of the battery swapping device 150 relative to the battery equipment with insufficient power.

[0104] S5: The battery replacement device 150 is lowered along the vertical direction DH relative to the third moving device 140 and places the low-battery battery device to the second storage position, and then the battery replacement device 150 is raised to leave the low-battery battery device.

[0105] S6: The second moving device 130 moves the battery replacement device 150 above the full-battery battery device, the battery replacement device 150 is lowered along the vertical direction DH relative to the third moving device 140 and grabs the full-battery battery device, and then the battery replacement device 150 carries the full-battery battery device to rise so that the full-battery battery device leaves the first storage position.

[0108] S9: The battery replacement device 150 is lowered along the vertical direction DH relative to the third moving device 140 and places the full-battery battery device to the vehicle, and then the battery replacement device 150 is raised to leave the full-battery battery device.

[0109] S10: The first moving device 120 moves relative to the box 111 along the first horizontal direction, so that the battery replacement device 150 returns to the inside of the box 111 via the access port 113, completing the battery replacement.

[0110] It should be noted that the position of the battery replacement device 150 relative to the vehicle can be further adjusted before the battery replacement device 150 grabs the low-battery battery device at the vehicle.
