Description

Technical Field

[0001] The present application relates to the field of battery swap stations, and in particular to a battery swap platform and a battery swap station. Background Art

[0002] Vehicles can have their batteries replaced at battery swap stations. Battery swap stations can be equipped with battery swap platforms and mobile battery swap devices, such as rail-guided vehicles (RGVs) that can replace batteries. When the vehicle is on the battery swap platform, the mobile battery swap device can transport the battery to the vehicle. The mobile battery swap device can remove the battery from the vehicle and install the battery to be installed in the battery compartment of the vehicle. For vehicles of various types, it is difficult for the mobile battery swap device to install the battery on the vehicle relatively accurately. Summary of the Invention

[0003] The present application provides a battery swap platform and a battery swap station, the purpose of which is to facilitate the relatively accurate installation of batteries on vehicles by mobile battery swap devices.

[0004] In a first aspect, a battery exchange platform is provided, comprising: a guide rail extending along a first direction, the guide rail being used to move a mobile battery exchange device along the first direction, the mobile battery exchange device being used to replace batteries for a vehicle, the guide rail comprising a first guide rail section and a second guide rail section; a first platform being used to fix the first guide rail section, the first platform being rotatable; a second platform being used to fix the second guide rail section, the second platform being arranged on the first platform and being rotatable with the first platform; and a translation drive assembly being used to drive the second platform to move relative to the first platform along a second direction to move the mobile battery exchange device along the second direction, wherein the second direction is perpendicular to the first direction.

[0005] The solution provided by the present application rotates the first platform to drive the second platform to rotate, and drives the second platform to move relative to the first platform in a direction perpendicular to the guide rail, so that when the mobile battery exchange device travels to the second guide rail section on the second platform, the mobile battery exchange device can move along the second guide rail section, and can move in a direction perpendicular to the second guide rail section, and the mobile battery exchange device can also rotate with the second platform. Through the battery exchange platform provided by the present application, the mobile battery exchange device can move in multiple directions, and the mobile battery exchange device can stay in more diverse positions on the battery exchange platform, so that the mobile battery exchange device can more easily adapt to multiple battery compartment positions. Therefore, the solution provided by the present application is conducive to improving the accuracy of battery installation in the mobile battery exchange device.

[0006] In one possible implementation, the second platform is contained within the first platform, and the first platform has a window that exposes the second platform. The first platform with the window allows the mobile battery swap device to move along the guide rails on the second platform, while the second platform and other components connected to the second platform are mechanically protected by the first platform.

[0007] In one possible implementation, a gap is defined between the first and second guide rail segments, and the gap corresponds to the edge of the window, allowing the second guide rail segment and the second platform to move in the second direction. Because the gap corresponds to the edge of the window, when the mobile battery swap device travels onto the second platform, it can move not only along the guide rail but also perpendicular to the guide rail, thereby increasing the movable space of the mobile battery swap device along and perpendicular to the guide rail.

[0008] In a possible implementation, the movement space of the second guide rail segment in the second direction is located within the window. The window can be used to limit the guide rail, which helps to reduce the risk of the guide rail detaching from the first platform.

[0009] In one possible implementation, the battery exchange platform further includes: a rack extending along the first direction, the rack including a first rack segment and a second rack segment, the first rack segment being fixed to the first platform, and the second rack segment being fixed to the second platform. The mobile battery exchange device may be provided with a gear that engages with the rack. When the mobile battery exchange device moves to the first platform, the gear of the mobile battery exchange device may engage with the first rack segment. When the mobile battery exchange device moves to the second platform, the gear of the mobile battery exchange device may engage with the second rack segment. By driving the second platform to move relative to the first platform, the second rack segment may follow the movement of the second platform, and the mobile battery exchange device may still engage with the rack, thereby facilitating flexible switching between a mode in which the mobile battery exchange device moves along the guide rail and a mode in which the mobile battery exchange device moves perpendicular to the guide rail.

[0010] In one possible implementation, the translation drive assembly includes a first fixing member fixedly connected to the second platform and configured to move in the second direction to drive the mobile battery exchange device to move in the second direction. The translation drive assembly can achieve movement of the second guide rail segment by controlling the displacement of the first fixing member, thereby facilitating movement of the second guide rail segment.

[0011] In one possible implementation, the second platform is provided with a slot, and the first fixing member is a boss that mates with the slot. This mating relationship between the slot and the boss allows the translation drive assembly to drive the second platform relative to the first platform. Furthermore, the fixed connection between the second platform and the translation drive assembly is relatively easy to access, facilitating removal of the second platform for inspection and maintenance of components within the battery swap platform.

[0012] In one possible implementation, the translation drive assembly further includes a screw, a drive nut, and a first motor; the screw extends along the second direction, the drive nut engages with the screw in a transmission manner; the drive nut is connected to the first fixing member, and the first motor is used to drive the screw to rotate, thereby causing the drive nut to move relative to the screw. The number of rotations of the screw can relatively accurately correspond to the displacement of the drive nut, which is conducive to improving the accuracy of the displacement of the mobile battery exchange device perpendicular to the guide rail.

[0013] In one possible implementation, a track extending along the second direction is fixed to the first platform, and the second platform is configured to move on the track. The track can limit the movement of the second platform, which helps to reduce the offset between the second platform's movement direction and the direction perpendicular to the guide rail, thereby helping to improve the displacement accuracy of the mobile battery swap device on the battery swap platform.

[0014] In one possible implementation, the battery swap platform further includes a rotation drive assembly configured to drive the first and second platforms to rotate as a whole. The rotation drive assembly can drive the first platform to rotate a specified angle, thereby improving the rotation accuracy of the mobile battery swap device on the battery swap platform.

[0015] In one possible implementation, the second platform is positioned in the center of the first platform, and the rotation drive assembly is configured to drive the first and second platforms to rotate about the center of the first platform. After the first and second platforms rotate as a whole, the distance between the mobile battery swapping device and the center of the first platform can be relatively close, thereby reducing the displacement of the mobile battery swapping device relative to the entire battery swapping platform after rotation and improving the efficiency of moving the mobile battery swapping device on the battery swapping platform.

[0016] In one possible implementation, the rotation drive assembly includes a second fixing member, which is fixedly connected to the first platform and is driven to rotate, thereby driving the first and second platforms to rotate as a whole. The rotation drive assembly can achieve rotation of the first and second platforms by controlling the rotation of the second fixing member, thereby facilitating the rotation of the second guide rail segment.

[0017] In one possible implementation, the second fixed member is a first gear, and the rotation drive assembly further includes a second gear and a second motor. The first and second gears are meshed, and the second motor is configured to rotate the second gear, thereby driving the first gear to rotate. The number of rotations of the second gear can relatively accurately correspond to the rotation angle of the first gear, thereby improving the rotation accuracy of the mobile battery exchange device.

[0018] In one possible implementation, the first gear is a ring gear surrounding the translation drive assembly, and the translation drive assembly is used to move the second platform within the area enclosed by the first gear. The translation drive assembly is housed within the area enclosed by the first gear, which helps reduce the overall space required on the battery swap platform to accommodate the translation drive assembly and the rotation drive assembly.

[0019] In the second aspect, a battery swap station is provided, comprising: a battery rack, a mobile battery swap device and the battery swap platform described in the first aspect or any possible implementation of the first aspect, wherein the battery rack is configured with multiple batteries, and the mobile battery swap device is used to transport the batteries on the battery rack to the battery swap platform and move along the first direction and / or the second direction on the battery swap platform to replace the batteries to the vehicle.

[0020] In the battery exchange platform and battery exchange station provided by the present application, the first guide rail section of the guide rail can be fixed to the rotatable first platform, the second guide rail section of the guide rail can be fixed to the second platform, the second platform can rotate with the first platform, and the translation drive assembly can be used to drive the second platform to move relative to the first platform in a direction perpendicular to the guide rail, so that the mobile battery exchange device can rotate on the battery exchange platform, translate along the guide rail, and translate perpendicular to the guide rail. Therefore, the mobile battery exchange device can have more diverse staying positions on the battery exchange platform, and the mobile battery exchange device can more easily adapt to multiple battery compartment positions. Therefore, the solution provided by the present application is conducive to improving the accuracy of battery installation in the mobile battery exchange device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be understood that the technical solutions described in the embodiments of the present application are not limited to the devices described above, but can also be applied to all devices using batteries. However, for the sake of simplicity, the following embodiments are explained using vehicles as an example.

[0039] Figure 1It is a structural diagram of a battery swap station 100 provided in one embodiment of the present application.

[0040] The battery swap station 100 may include a battery rack 101. The battery rack 101 may be configured with multiple batteries. The battery rack 101 may include a battery charging compartment and a battery caching device. Batteries may be stored in the battery charging compartment so that they can be charged. The battery rack 101 may be configured with a battery caching device. The battery caching device may be used to place batteries to be stored or charged in the battery charging compartment, and also to remove fully charged batteries or batteries to be removed from the battery charging compartment.

[0041] In one embodiment, the battery rack 101 may further include a fire protection transmission device, which may be used to maintain fire protection safety of the battery swap station 100 .

[0042] The battery swap station 100 may further include a stacker 102, a mobile battery swap device ( Figure 1 (not shown). The palletizer 102 can be used to transport the batteries replaced by the mobile battery exchange device from the vehicle 1 to the battery cache device. The battery cache device can place the batteries to be charged in the empty battery charging compartment to charge the batteries to be charged. The palletizer 102 can also be used to remove the batteries to be installed on the battery cache device, and to move the batteries to be installed to the docking position of the mobile battery exchange device. The mobile battery exchange device can be used to remove the batteries to be installed from the palletizer 102 and transport the batteries to be installed to the vicinity of the vehicle 1. The mobile battery exchange device can also transport the batteries removed from the vehicle 1 to the palletizer 102.

[0043] The battery swap station 100 may further include a battery swap platform 200 . Figure 2 A schematic diagram of a vehicle 1 traveling on a battery swap platform 200 is shown. On the battery swap platform 200, a mobile battery swap device can replace the battery on the vehicle 1. Figure 1 The X direction in may be the driving direction of the vehicle 1 on the battery swap platform 200 . Figure 1 The Y direction in the figure can be the driving direction of the mobile battery swap device on the battery swap platform 200. The mobile battery swap device can be moved along the Y direction to the vicinity of the vehicle 1 through the guide rails on the battery swap platform 200. Vehicle 1 can replace the battery on the battery swap platform 200 through the mobile battery swap device. The mobile battery swap device can be used to transport the batteries on the battery rack 101 to the battery swap platform 200. The mobile battery swap device can travel on the battery swap platform 200 and move to the position of the battery compartment 20 corresponding to the vehicle 1 to remove the battery to be charged in the battery compartment 20 and install the battery to be installed into the battery compartment 20 so that the battery can be replaced to the vehicle 1. The mobile battery swap device can be, for example, an RGV.

[0044] In one embodiment, the mobile battery exchange device may include a disassembly mechanism and a lifting mechanism. When the mobile battery exchange device is aligned with the battery in the battery compartment 20 of the vehicle 1, the lifting mechanism can be used to lift the disassembly mechanism. The disassembly mechanism can remove the battery in the battery compartment 20 so that the battery in the battery compartment 20 can fall into the mobile battery exchange device. When the mobile battery exchange device moves to the battery cache device, the lifting mechanism can place the battery carried by the mobile battery exchange device on the battery cache device by lifting the battery. When the mobile battery exchange device carries the battery to be installed and drives to a position aligned with the battery compartment 20, the lifting mechanism can be used to lift the battery to be installed so as to load the battery to be installed into the battery compartment 20.

[0045] exist Figure 1 and Figure 2 In the embodiment shown, the battery exchange platform 200 may further include a vehicle lifting mechanism 107, a front ramp 104, a front wheel positioning roller 106, a rear ramp 103, and a rear wheel positioning roller 105. The vehicle 1 can travel from the rear ramp 103 toward the front ramp 104, as shown in FIG. Figure 2 As shown. Along the driving direction of the vehicle 1, the front wheel positioning roller 106 and the rear wheel positioning roller 105 can be located between the front ramp 104 and the rear ramp 103. The front wheel positioning roller 106 can be set close to the front ramp 104, and the rear wheel positioning roller 105 can be set close to the rear ramp 103. The front wheel positioning roller 106 can be used to position the front wheels of the vehicle 1. The rear wheel positioning roller 105 can be used to position the rear wheels of the vehicle 1. The battery swap platform 200 can position the vehicle 1 in the X direction and the Y direction through the front wheel positioning roller 106 and the rear wheel positioning roller 105, so that the vehicle 1 can be fixed relative to the battery swap platform 200. When the battery swap platform 200 completes the positioning of the vehicle 1, the vehicle lifting mechanism 107 can be triggered to lift the vehicle 1. Positioning and lifting the battery swap vehicle 1 can be a preparatory step in the battery swap process. After the vehicle 1 completes the battery swap, the vehicle lifting mechanism 107 can lower the vehicle 1 back to the battery swap platform 200.

[0046] Figure 3 1 shows a schematic structural diagram of the battery compartment 20 viewed from the bottom of the vehicle 1 in one embodiment.

[0047] The vehicle 1 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended range vehicle. A motor, a controller and a battery 10 can be set inside the vehicle 1. The controller is used to control the battery 10 to supply power to the motor. In some embodiments, Figure 3As shown, a battery 10 can be installed at the bottom of the vehicle 1. In other embodiments, the battery 10 can be installed at the front or rear of the vehicle. The battery 10 can be used to power the vehicle 1. For example, the battery 10 can serve as the operating power source of the vehicle 1 and be used for the circuit system of the vehicle 1, such as the operating power requirements of the vehicle 1 during startup, navigation, and operation. In another embodiment of the present application, the battery 10 can not only serve as the operating power source of the vehicle 1, but also as the driving power source of the vehicle 1, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1.

[0048] For vehicles 1 of different models, the shape and size of their battery compartments 20 may be different due to mechanical structural limitations. In order to adapt to different models, the battery 10 can adopt a subcontracting mode, that is, the battery 10 can have a smaller size. For example, the volume of the battery 10 can be approximately 1 / N of the volume of the battery compartment 20, where N can be a different positive integer value for different models. In this way, for different models, corresponding N batteries 10 can be used, so that the battery 10 can be adapted to different models. At the same time, due to the reduction in the size of the battery 10, the space occupied by the battery swap station 100 can also be reduced, thereby reducing the floor space of the battery swap station 100 and reducing the cost of the battery swap station 100.

[0049] For example, the volume of the battery 10 may be Figure 3 The volume of the battery compartment 20 shown is half. Figure 3 The battery compartment 20 shown can accommodate two batteries 10. Figure 3 A battery compartment with half the volume of the battery compartment 20 shown can accommodate one battery 10. A larger battery compartment can accommodate more batteries 10.

[0050] Figure 4 The following figure shows a schematic diagram of the structure of a battery 10 provided by one embodiment of the present application. To meet different power requirements, battery 10 can include multiple battery cells. Battery 10 can also include a housing, which has a hollow interior and houses the multiple battery cells. For example, the multiple battery cells can be connected in parallel, in series, or in a hybrid combination and then placed in the housing.

[0051] Optionally, the battery 10 may also include other structures, which will not be described in detail here. For example, the battery 10 may also include a busbar component, which is used to achieve electrical connection between multiple battery cells, such as parallel connection, series connection, or mixed connection. Specifically, the busbar component can achieve electrical connection between battery cells by connecting the electrode terminals of the battery cells. Furthermore, the busbar component can be fixed to the electrode terminals of the battery cells by welding. The electrical energy of multiple battery cells can be further led out through the box through a conductive mechanism. Optionally, the conductive mechanism may also belong to the busbar component.

[0052] The number of battery cells can be set to any value based on different power requirements. Multiple battery cells can be connected in series, parallel, or in a hybrid manner to achieve a larger capacity or power. Since each battery 10 may include a large number of battery cells, for ease of installation, the battery cells can be grouped, with each group of battery cells forming a battery module. The number of battery cells included in a battery module is not limited and can be set according to requirements. The battery 10 may include multiple battery modules, which can be connected in series, parallel, or in a hybrid manner.

[0053] Optionally, the volume of the battery 10 may be 1 / N of the volume of the battery compartment 20 . Accordingly, the number of battery cells may be set according to the volume of the battery 10 .

[0054] Accordingly, the battery compartment 20 can accommodate multiple batteries. Figure 3 and Figure 4 In the embodiment shown, the battery compartment 20 can accommodate two batteries. In other embodiments, the battery compartment 20 of the vehicle can accommodate a greater or lesser number of batteries. In addition, the positions of the battery compartments 20 of different types of vehicles are different. During the battery swapping process, the position of the vehicle on the battery swapping platform 200 is relatively fixed. Since the mobile battery swapping device moves along the guide rails, the guide rails limit the movable space of the mobile battery swapping device, making it impossible for the mobile battery swapping device to accurately match a variety of battery compartment 20 positions.

[0055] The embodiment of the present application provides a battery swap platform 200 and a battery swap station 100. By fixing the first guide rail section 211 of the guide rail 210 to the rotatable first platform 220 and fixing the second guide rail section 212 of the guide rail 210 to the second platform 230, the second platform 230 can rotate along with the first platform 220, and the translation drive component 240 drives the second platform 230 to move relative to the first platform 220 in a direction perpendicular to the guide rail 210, so that the mobile battery swap device 108 can rotate on the battery swap platform 200, translate along the guide rail 210, and translate perpendicular to the guide rail 210. Therefore, the mobile battery swap device 108 can have more diverse parking positions on the battery swap platform 200, which is conducive to the mobile battery swap device 108 accurately matching a variety of battery compartment 20 positions.

[0056] Figure 5 and Figure 6 This is a schematic diagram of the structure of a battery swap platform 200 provided in one embodiment of the present application. In some embodiments, Figure 5 and Figure 6 The battery swap platform 200 shown can be applied to Figure 1 The battery swap station 100 shown. The battery swap platform 200 may include a guide rail 210, a first platform 220, a second platform 230, and a translation drive assembly 240.

[0057] The guide rail 210 extends along the first direction Y. The guide rail 210 is used to move the mobile battery exchange device 108 along the first direction Y. The mobile battery exchange device 108 is used to Figure 2 The vehicle 1 shown is replacing a battery. The mobile battery swapping device 108 can move along the guide rail 210. For example, the mobile wheels of the mobile battery swapping device 108 can cooperate with the guide rail 210. The extension direction of the guide rail 210 can be a first direction Y. The first direction Y can be the direction of travel of the mobile battery swapping device 108.

[0058] The guide rail 210 includes a first guide rail segment 211 and a second guide rail segment 212. The first guide rail segment 211 and the second guide rail segment 212 may be two separable sections of the guide rail 210. The extending direction of the first guide rail segment 211 and the extending direction of the second guide rail segment 212 may be a first direction Y.

[0059] The first platform 220 is used to fix the first guide rail segment 211. The first platform 220 is rotatable. In some embodiments, when the first platform 220 rotates, the first guide rail segment 211 can rotate along with the first platform 220.

[0060] The second platform 230 is used to fix the second guide rail segment 212. The second platform 230 is disposed on the first platform 220 and can rotate with the first platform 220. In some embodiments, when the first platform 220 rotates, the second platform 230 and the second guide rail segment 212 can rotate with the first platform 220.

[0061] When the mobile battery-exchanging device 108 cooperates with the first guide rail segment 211 and the first platform 220 is rotated, the first guide rail segment 211 can rotate along with the first platform 220 , thereby rotating the mobile battery-exchanging device 108 .

[0062] When the mobile battery exchange device 108 cooperates with the second guide rail segment 212 and the first platform 220 is rotated, the second platform 230 can rotate along with the first platform 220 and the second guide rail segment 212 can rotate along with the second platform 230, thereby rotating the mobile battery exchange device 108.

[0063] The translation drive assembly 240 is used to drive the second platform 230 to move relative to the first platform 220 along the second direction X to move the mobile battery exchange device 108 along the second direction X, wherein the second direction X is perpendicular to the first direction Y. The second direction X can be parallel to Figure 2 The direction of travel of vehicle 1 is shown.

[0064] When the translation drive assembly 240 is not driving the second platform 230 to move, one end of the first guide rail segment 211 and one end of the second guide rail segment 212 can be arranged to face each other. The mobile battery exchange device 108 can move along the guide rail 210 in the first direction Y. In one embodiment, the mobile battery exchange device 108 can move from the first guide rail segment 211 to the second guide rail segment 212.

[0065] When the mobile battery-exchanging device 108 cooperates with the second guide rail segment 212 and the translation drive assembly 240 moves the second platform 230 along the second direction X, the second guide rail segment 212 fixed on the second platform 230 can move along the second direction X with the second platform 230, so that the mobile battery-exchanging device 108 can move along the second direction X. The first guide rail segment 211 fixed on the first platform 220 can remain stationary relative to the battery-exchanging platform 200 as a whole.

[0066] It should be understood that the battery swap platform 200 may also include a greater number of guide rails 210. Figure 5 As shown, the battery swap platform 200 can move the mobile battery swap device 108 through two guide rails 210. The embodiment provided in this application is described by taking one guide rail 210 as an example. The embodiment of the battery swap platform 200 with multiple guide rails 210 can refer to the embodiment provided in this application.

[0067] Optionally, the second platform 230 is contained within the first platform 220, and the first platform 220 has a window 2230, wherein the window 2230 is used to expose the second platform 230. In other words, the second platform 230 can be accommodated in the cavity of the first platform 220; the second guide rail segment 212 fixed on the second platform 230 can cooperate with the mobile battery exchange device 108 through the window 2230 of the first platform 220.

[0068] The first platform 220 may include a first mounting seat 221, a bracket 222, and a first cover plate 223. The first cover plate 223 and the first mounting seat 221 may be arranged parallel to each other. The bracket 222 may be fixed to the first mounting seat 221 and used to support the first cover plate 223 on the first mounting seat 221. The space enclosed by the first mounting seat 221, the bracket 222, and the first cover plate 223 may be used to accommodate some components of the battery swap platform 200. The first cover plate 223 has a window 2230. Some components housed within the first platform 220 may be observed through the window 2230. The second platform 230 may be at least partially housed within the space enclosed by the first mounting seat 221, the bracket 222, and the first cover plate 223, and may be visible through the window 2230 on the first cover plate 223. In other words, the second platform 230 may obscure the window 2230 on the first cover plate 223 so that components located within the first platform 220 are not exposed through the window 2230.

[0069] In one embodiment, the second platform 230 may be entirely located between the first mounting base 221 and the first cover plate 223. Figure 5 As shown. The second platform 230 may include a second mounting base 231 and a second cover plate 232. The second cover plate 232 may be mounted on the second mounting base 231 using, for example, a fixing connector. The second mounting base 231 may be fixed to the first platform 220 and located within the space enclosed by the first mounting base 221, the bracket 222, and the first cover plate 223. The second cover plate 232 may be located between the first cover plate 223 and the second mounting base 231. The second cover plate 232 may be arranged parallel to the first cover plate 223.

[0070] In another embodiment, a portion of the second platform 230 may be located between the first mounting seat 221 and the first cover plate 223, and another portion may extend out of the window 2230. For example, a fixed connection member connecting the second cover plate 232 and the second mounting seat 231 may pass through the window 2230. The second cover plate 232 may be located on a side of the first cover plate 223 away from the first mounting seat 221.

[0071] When the mobile battery swap device 108 moves to the first platform 220, the mobile battery swap device 108 can cooperate with the first rail section 211 of the guide rail 210. When the mobile battery swap device 108 moves to the second platform 230, the mobile battery swap device 108 can cooperate with the second rail section 212 of the guide rail 210.

[0072] In one embodiment, the first guide rail segment 211 may be fixed to a side of the first cover plate 223 away from the first mounting seat 231 . The second guide rail segment 212 may be fixed to a side of the second cover plate 232 away from the second mounting seat 232 .

[0073] In another embodiment, the guide rail 210 may be disposed below the first cover plate 223 and the second cover plate 232. The first cover plate 223 and the second cover plate 232 may both provide mechanical protection for the guide rail 210.

[0074] like Figure 5 As shown, the first cover plate 223 may include a first gap corresponding to the first guide rail segment 211. Through the first gap, the first guide rail segment 211 can expose the first cover plate 223. The first guide rail segment 211 or the mobile battery exchange device 108 can pass through the first gap to achieve the cooperation between the first guide rail segment 211 and the mobile battery exchange device 108. In one embodiment, the first guide rail segment 211 can be fixed on the first mounting base 221.

[0075] Similarly, the second cover plate 232 may include a second gap corresponding to the second guide rail segment 212. Through the second gap, the second guide rail segment 212 may be exposed from the second cover plate 232. The second guide rail segment 212 or the mobile battery exchange device 108 may pass through the second gap to achieve cooperation between the second guide rail segment 212 and the mobile battery exchange device 108. In one embodiment, the second guide rail segment 212 may be fixed to the second mounting base 231.

[0076] In some embodiments, to reduce the bumping of the mobile battery swap device 108 , the surface of the first guide rail segment 211 close to the vehicle may be flush with the surface of the second guide rail segment 212 close to the vehicle.

[0077] Optionally, a first slit 213 is defined between the first guide rail segment 211 and the second guide rail segment 212 . The first slit 213 corresponds to an edge of the window 2230 , allowing the second guide rail segment 212 and the second platform 230 to move in the second direction X. In other words, by providing the first slit 213 on the guide rail 210 , the guide rail 210 can be divided into the first guide rail segment 211 and the second guide rail segment 212 . The first guide rail segment 211 and the second guide rail segment 212 can be located on either side of the first slit 213 , respectively.

[0078] When the translation drive assembly 240 does not drive the second platform 230 to move, one end of the first guide rail segment 211 and one end of the second guide rail segment 212 can be arranged facing each other. In order to reduce the mutual interference between the first guide rail segment 211 and the second guide rail segment 212 due to reasons such as vibration of the entire machine, a first break 213 can be provided between the first guide rail segment 211 and the second guide rail segment 212. In the embodiment provided in the present application, the break can also be referred to as a notch, a gap, etc. The width of the first break 213 should not be too large, so as to help reduce the degree of bumping of the mobile battery exchange device 108 at the first break 213.

[0079] After the translation drive assembly 240 drives the second platform 230 to move, since the first guide rail segment 211 and the second guide rail segment 212 are not connected, the second guide rail segment 212 can gradually move away from the first guide rail segment 211. The first guide rail segment 211 and the second guide rail segment 212 can be separated. In addition, the translation drive assembly 240 can also drive the second platform 230 to move the second guide rail segment 212 back to the vicinity of the first guide rail segment 211.

[0080] The first break 213 corresponds to the edge of the window 2230, which may mean that the distance from the first break 213 to the edge of the window 2230 is smaller. The first break 213 may be located, for example, within the area enclosed by the window 2230, or outside the area enclosed by the window 2230. In one embodiment, the width of the window 2230 in the extension direction of the second guide rail segment 212 may be close to the length of the second guide rail segment 212. Since the first break 213 corresponds to the edge of the window 2230, when the mobile battery exchange device 108 is located as a whole on the second platform 230, the mobile battery exchange device 108 may only cooperate with the second guide rail segment 212, but not with the first guide rail segment 211. Therefore, the movable space in which the mobile battery exchange device 108 can move in a direction perpendicular to the guide rail 210 may correspond to the area enclosed by the window 2230.

[0081] Optionally, the movable space of the second guide rail segment 212 in the second direction X is located within the window 2230. Since the second guide rail segment 212 is located within the area enclosed by the window 2230, the second guide rail segment 212 can be prevented from moving out of the window 2230. Therefore, the window 2230 can limit the movable space of the second guide rail segment 212 in the direction perpendicular to the guide rail 210.

[0082] Figure 7 Schematic diagram of the structure of the battery swap platform 100 after the translation drive assembly 240 moves the second platform 230. Figure 7 As shown, in one embodiment, after the second platform 230 moves relative to the first platform 220, the second cover 232 can partially cover the window 2230. In other embodiments, after the second platform 230 moves relative to the first platform 220, the second cover 232 can still cover all the windows 2230.

[0083] Optionally, the battery swap platform 200 further includes a rack 260. The rack 260 extends along the first direction Y. That is, the extension direction of the rack 260 may be consistent with the extension direction of the guide rail 210. The mobile battery swap device 108 may have a gear ( Figure 5 (not shown). The mobile power-exchanging device 108 can drive the gear to rotate, and through the meshing relationship between the rack 260 and the gear, the mobile power-exchanging device 108 can move along the extension direction of the rack 260.

[0084] The rack 260 includes a first rack segment 261 and a second rack segment 262 . The first rack segment 261 is fixed to the first platform 220 , and the second rack segment 262 is fixed to the second platform 230 .

[0085] In some embodiments, when the first platform 220 rotates, the first rack segment 261 and the second rack segment 262 may rotate along with the first platform 220 .

[0086] When the gear of the mobile battery-exchanging device 108 is engaged with the first rack segment 261 and the first platform 220 is rotated, the first rack segment 261 can rotate along with the first platform 220 , thereby rotating the mobile battery-exchanging device 108 .

[0087] When the gear of the mobile battery exchange device 108 engages with the second rack segment 262 and the first platform 220 is rotated, the second platform 230 can rotate along with the first platform 220 and the second rack segment 262 can rotate along with the second platform 230 , thereby rotating the mobile battery exchange device 108 .

[0088] When the translation drive assembly 240 is not driving the second platform 230 to move, one end of the first rack segment 261 and one end of the second rack segment 262 can be positioned facing each other. The gear of the mobile battery exchange device 108 can engage with the rack 260 to enable the mobile battery exchange device 108 to move along the first direction Y. In one embodiment, the mobile battery exchange device 108 can move from the first rack segment 261 to the second rack segment 262.

[0089] When the gear of the mobile battery-exchanging device 108 can mesh with the second rack segment 262, and the translation drive assembly 240 moves the second platform 230 along the second direction X, the second rack segment 262 fixed on the second platform 230 can follow the second platform 230 to move along the second direction X, so that the mobile battery-exchanging device 108 and the second rack segment 262 can move synchronously along the second direction X. The first rack segment 261 fixed on the first platform 220 can remain stationary relative to the battery-exchanging platform 200 as a whole.

[0090] When the mobile battery swap device 108 moves to the first platform 220 , the gear of the mobile battery swap device 108 can mesh with the first rack segment 261 . When the mobile battery swap device 108 moves to the second platform 230 , the gear of the mobile battery swap device 108 can mesh with the second rack segment 262 .

[0091] In one embodiment, the first rack segment 261 can be fixed to the first cover plate 223 of the first platform 220, for example, located on a side of the first cover plate 223 away from the first mounting base 221. The second rack segment 262 can be fixed to the second cover plate 232 of the second platform 230, for example, located on a side of the second cover plate 232 away from the second mounting base 231.

[0092] In another embodiment, the rack 260 may be disposed below the first cover plate 223 and the second cover plate 232 , and both the first cover plate 223 and the second cover plate 232 may provide mechanical protection for the rack 260 .

[0093] like Figure 5As shown, the first cover plate 223 may include a third gap corresponding to the first rack segment 261. Through the third gap, the first rack segment 261 can be exposed outside the first cover plate 223. The first rack segment 261 or the gear of the mobile battery exchange device 108 can pass through the third gap to achieve gear engagement between the first rack segment 261 and the mobile battery exchange device 108. In one embodiment, the first rack segment 261 can be fixed to the first mounting base 221.

[0094] Similarly, the second cover plate 232 may include a fourth slit corresponding to the second rack segment 262. The second rack segment 262 may be exposed from the second cover plate 232 through the fourth slit. The second rack segment 262 or a gear of the mobile battery exchange device 108 may pass through the fourth slit to achieve gear meshing between the second rack segment 262 and the mobile battery exchange device 108. In one embodiment, the second rack segment 262 may be fixed to the second mounting base 231.

[0095] In some embodiments, in order to reduce the bumps of the mobile battery exchange device 108 , the tooth surface of the first rack segment 261 can smoothly transition with the tooth surface of the second rack segment 262 .

[0096] Optionally, a second slit is provided between the first rack segment 261 and the second rack segment 262 , and the second slit corresponds to an edge of the window 2230 , so that the second rack segment 262 and the second platform 230 can move in the second direction X. In other words, by providing the second slit on the rack 260 , the rack 260 can be divided into a first rack segment 261 and a second rack segment 262 , with the first rack segment 261 and the second rack segment 262 being located on either side of the second slit, respectively.

[0097] When the translation drive assembly 240 is not driving the second platform 230 to move, one end of the first rack segment 261 and one end of the second rack segment 262 can be positioned facing each other. To reduce interference between the first and second rack segments 261, 262 due to vibrations of the entire device, a second gap can be defined between the first and second rack segments 261, 262. The width of this second gap should not be too large to minimize the time it takes for the gears of the mobile battery exchange device 108 to disengage from the rack 260 during movement.

[0098] After the translation drive assembly 240 drives the second platform 230 to move, since the first rack segment 261 and the second rack segment 262 are not connected, the second rack segment 262 can gradually move away from the first rack segment 261. The first rack segment 261 and the second rack segment 262 can be separated. In addition, the translation drive assembly 240 can also drive the second platform 230 to move the second rack segment 262 back to the vicinity of the first rack segment 261.

[0099] The second break corresponds to the edge of the window 2230, which may mean that the distance from the second break to the edge of the window 2230 is smaller. The second break may be located, for example, within the area enclosed by the window 2230, or outside the area enclosed by the window 2230. In one embodiment, the width of the window 2230 in the extension direction of the second rack segment 262 may be close to the length of the second rack segment 262. Since the second break corresponds to the edge of the window 2230, when the mobile battery exchange device 108 is located as a whole on the second platform 230, the gear of the mobile battery exchange device 108 may only engage with the second rack segment 262, but not with the first rack segment 261. Therefore, the movable space in which the mobile battery exchange device 108 can move in a direction perpendicular to the rack 260 may correspond to the area enclosed by the window 2230.

[0100] Optionally, the movement space of the second rack segment 262 in the second direction X is located within the window 2230. Since the second rack segment 262 is located within the area enclosed by the window 2230, the second rack segment 262 can be prevented from moving out of the window 2230. Therefore, the window 2230 can limit the movement space of the second rack segment 262 in a direction perpendicular to the rack 260.

[0101] It should be understood that the battery swap platform 200 may also include a larger number of racks 260. The embodiment provided in this application is described with one rack 260 as an example. The embodiment of the battery swap platform 200 with multiple racks 260 can refer to the embodiment provided in this application.

[0102] Alternatively, as Figure 6 and Figure 8 As shown, the translation drive assembly 240 includes a first fixing member, which is used to be fixedly connected to the second platform 230. The first fixing member is configured to move along the second direction X to drive the mobile power exchange device 108 to move along the second direction X. In other words, the first fixing member can be fixedly connected to the second platform 230, and the translation drive assembly 240 drives the first fixing member to move along the second direction X to drive the second platform 230 to move along the second direction X. Since the second guide rail segment 212 can move along the second direction X with the second platform 230, the mobile power exchange device 108 that cooperates with the second guide rail segment 212 can move along the second direction X.

[0103] Optionally, the second platform 230 is provided with a slot 242, and the first fixing member is a boss 241 that cooperates with the slot 242. The slot 242 can be a through slot or a blind slot. That is to say, the boss 241 of the translation drive assembly 240 can extend into the slot 242 of the second platform 230 and engage with the slot 242. In some embodiments, the boss 241 and the slot 242 can be fixed by means of glue or the like. The fixed connection relationship between the translation drive assembly 240 and the second platform 230 can be achieved by the cooperation between the slot 242 and the boss 241. By removing the boss 241 from the slot 242, the fixed connection relationship between the translation drive assembly 240 and the second platform 230 can be released.

[0104] Optionally, the translation drive assembly 240 also includes a screw rod 243, a transmission nut 244, and a first motor 245; the screw rod 243 extends along the second direction X, and the transmission nut 244 is in transmission cooperation with the screw rod 243; the transmission nut 244 is connected to the first fixing member, and the first motor 245 is used to drive the screw rod 243 to rotate, so as to drive the transmission nut to move relative to the screw rod 243.

[0105] Figure 8 A schematic structural diagram of a translation drive assembly 240 provided in an embodiment of the present application is shown. A first motor 245 can drive a screw rod 243 to rotate. Through the cooperation between the screw rod 243 and the drive nut 244, the drive nut 244 can move along the extension direction of the screw rod 243. Because the screw rod 243 extends along the second direction X, the drive nut 244 can move along the second direction X. Because the drive nut 244 is connected to the first fixing member, the first fixing member can move along the second direction X, thereby driving the second platform 230 to move along the second direction X.

[0106] In some embodiments, the translation drive assembly 240 can be fixed to the first mounting base 221 of the first platform 220. For example, Figure 6 and Figure 8 The first motor 245 can be fixed to the first mounting base 221 of the first platform 220. One end of the screw rod 243 can be connected to the first motor 245, and the other end of the screw rod 243 can pass through the screw rod support member 246, which can be fixed to the first mounting base 221. The first fixing member can be fixed to the side of the transmission nut 244 near the second mounting base 231.

[0107] In one embodiment, Figure 6As shown, the second mounting base 231 may include an opening disposed opposite the first motor 245. The first motor 245 may pass through the opening. The height of the first motor 245 may be relatively high. By providing an opening on the second mounting base 231 opposite the first motor 245, it is helpful to reduce the space occupied by the first motor 245 and the second mounting base 231 as a whole in the height direction. In addition, since the second mounting base 231 can move along the second direction X, by providing an opening on the second mounting base 231 corresponding to the first motor 245, it is helpful to reduce the possibility of interference between the second mounting base 231 and the first motor 245.

[0108] Optionally, a track 270 extending along the second direction X is fixed to the first platform 220, and the second platform 230 is configured to move on the track 270. That is, the track 270 can be used to limit the movement of the second platform 230 along the second direction X. In one embodiment, the track 270 can be fixed to the first mounting seat 221 of the first platform 220 and located between the first mounting seat 221 and the second mounting seat 231 of the second platform 230. A moving member that cooperates with the track 270 can be provided on one side of the second mounting seat 231 close to the first mounting seat 221, so that the second platform 230 can move on the track 270. Through the track 270, the second platform 230 can deviate from the preset direction relatively less when moving, and the preset direction can be perpendicular to the extension direction of the guide rail 210.

[0109] Optionally, the battery swap platform 200 further includes a rotation drive assembly. The rotation drive assembly 250 is used to drive the first platform 220 and the second platform 230 to rotate as a whole. In other words, the battery swap platform 200 can achieve rotation of the first platform 220 and the second platform 230, and translation of the second platform 230, respectively, through the rotation drive assembly 250 and the translation drive assembly 240.

[0110] Optionally, the second platform 230 is disposed in the central area of ​​the first platform 220, and the rotation drive assembly 250 is used to drive the first platform 220 and the second platform 230 to rotate around the center of the first platform 220. When the mobile battery exchange device 108 moves to the second platform 230, the rotation drive assembly 250 can rotate the first platform 220, so that the mobile battery exchange device 108 can rotate relative to the center of the first platform 220. Since the second platform 230 is located in the central area of ​​the first platform 220, the mobile battery exchange device 108 can rotate along the center of the second platform 230. In one embodiment, when the mobile battery exchange device 108 is located in the central area of ​​the second platform 230, the rotation drive assembly 250 can drive the first platform 220 and the second platform 230 to rotate around the center of the first platform 220.

[0111] Optionally, the rotation drive assembly 250 includes a second fixing member, which is used to fixedly connect to the first platform 220. The second fixing member is driven to rotate to drive the first platform 220 and the second platform 230 to rotate as a whole. In other words, since the second fixing member can be fixedly connected to the first platform 220, the rotation drive assembly 250 drives the first platform 220 to rotate by driving the second fixing member. Since the second platform 230 can rotate with the first platform 220, the mobile battery exchange device 108 that cooperates with the second guide rail segment 212 can be rotated.

[0112] Optionally, the second fixing member is a first gear 253, and the rotation drive assembly 250 further includes a second gear 252 and a second motor 251. The first gear 253 and the second gear 252 are engaged, and the second motor 251 is used to drive the second gear 252 to rotate, thereby driving the first gear 253 to rotate. In other words, the second motor 251 can drive the second gear 252 to rotate. Through the engagement of the second gear 252 and the first gear 253, the first gear 253 can rotate around the center of the first gear 253 itself. Since the first gear 253 is fixedly connected to the first platform 220, the first platform 220 can rotate following the first gear 253. In one embodiment, the center of the first gear 253 can be aligned with the center of the first platform 220. In one embodiment, the first gear 253 can be fixed on the first mounting base 221 of the first platform 220.

[0113] In some embodiments, a portion of the rotation drive assembly 250 may be contained within the first platform 220, and another portion may be located outside the first platform 220. For example, Figure 6 As shown, the first gear 253 is contained within the cavity formed by the first mounting base 221, the bracket 222, and the first cover plate 223. The second gear 252 can partially extend out of the cavity formed by the first mounting base 221, the bracket 222, and the first cover plate 223, and the second motor 251 can be located outside the cavity formed by the first mounting base 221, the bracket 222, and the first cover plate 223.

[0114] Optionally, the first gear 253 is a ring gear surrounding the translation drive assembly 240, and the translation drive assembly 240 is used to move the second platform 230 within the area enclosed by the first gear 253. In other words, the translation drive assembly 240 can be located within the area enclosed by the first gear 253. Accordingly, the second platform 230 can move within the area enclosed by the first gear 253. In one embodiment, the track 270 that cooperates with the second platform 230 during movement can be located within the area enclosed by the first gear 253.

[0115] The following combination Figures 1 to 8 The illustrated embodiments illustrate multiple possible application scenarios of the solutions provided by the embodiments of the present application.

[0116] In some embodiments, as Figure 3 、 Figure 4 As shown, the battery 10 may be in the shape of an elongated strip. A plurality of batteries 10 may be arranged in the battery compartment 20 of the vehicle 1. The long side of the battery 10 may be perpendicular to the travel direction X of the vehicle 1. The arrangement direction of the batteries 10 in the battery compartment 20 may be along the travel direction X of the vehicle 1.

[0117] When the vehicle 1 drives to the battery exchange platform 200, the mobile battery exchange device 108 can move along the extension direction Y of the guide rail to the bottom of the battery compartment 20 of the vehicle 1, and the extension direction Y of the guide rail can be perpendicular to the driving direction X of the vehicle 1.

[0118] In one possible scenario, the long side direction of the battery 10 carried by the mobile battery swap device 108 can be parallel to the extension direction Y of the guide rail. In this case, in addition to moving along the extension direction Y of the guide rail, the mobile battery swap device 108 also needs to move in a direction perpendicular to the guide rail, so that the mobile battery swap device 108 can install multiple batteries 10 arranged along the driving direction X of the vehicle 1.

[0119] According to the embodiment provided above, the mobile battery exchange device 108 can move along the extension direction Y of the guide rail on the first platform or the second platform; the second platform can be driven to move in a direction perpendicular to the guide rail through the translation drive component, so that the mobile battery exchange device 108 can move along the driving direction X of the vehicle 1 to install multiple batteries 10 into the battery compartment 20 of the vehicle 1.

[0120] In another possible scenario, the long side direction of the battery 10 carried by the mobile battery swap device 108 can be perpendicular to the extension direction Y of the guide rail. In this case, the mobile battery swap device 108 needs to be rotated 90° so that the long side direction of the battery 10 carried by the mobile battery swap device 108 can be perpendicular to the driving direction X of the vehicle 1.

[0121] After the mobile battery swap device 108 is rotated 90°, the guide rails that cooperate with the mobile battery swap device 108 can be rotated, and the extension direction of the guide rails after the rotation can be parallel to the travel direction X of the vehicle 1. The mobile battery swap device 108 can move on the guide rails along the travel direction X of the vehicle 1. In this way, the mobile battery swap device 108 can install multiple batteries 10 into the battery compartment 20 of the vehicle 1.

[0122] In other embodiments, the battery 10 may be in an elongated shape. Multiple batteries 10 may be disposed in the battery compartment 20 of the vehicle 1. The long sides of the batteries 10 may be parallel to the travel direction X of the vehicle 1. The batteries 10 may be arranged in the battery compartment 20 perpendicular to the travel direction X of the vehicle 1.

[0123] When the vehicle 1 drives to the battery exchange platform 200, the mobile battery exchange device 108 can move along the extension direction Y of the guide rail to the bottom of the battery compartment 20 of the vehicle 1, and the extension direction Y of the guide rail can be perpendicular to the driving direction X of the vehicle 1.

[0124] In one possible scenario, the long side direction of the battery 10 carried by the mobile battery swap device 108 can be parallel to the extension direction Y of the guide rail. In this case, the mobile battery swap device 108 needs to be rotated 90° so that the long side direction of the battery 10 carried by the mobile battery swap device 108 can be parallel to the driving direction X of the vehicle 1.

[0125] After the mobile battery swap device 108 is rotated 90°, the guide rail that cooperates with the mobile battery swap device 108 can be rotated, and the extension direction of the guide rail after rotation can be parallel to the driving direction X of the vehicle 1. Since the batteries 10 are arranged in the battery compartment 20 perpendicular to the driving direction X of the vehicle 1, the mobile battery swap device 108 also needs to be moved perpendicular to the driving direction X of the vehicle 1.

[0126] According to the embodiment provided above, the second platform can be driven to move in a direction perpendicular to the guide rail through the translation drive component, so that the mobile battery exchange device 108 can move in a direction perpendicular to the driving direction X of the vehicle 1 to install multiple batteries 10 into the battery compartment 20 of the vehicle 1.

[0127] In another possible scenario, the long side direction of the battery 10 carried by the mobile battery swap device 108 can be perpendicular to the extension direction Y of the guide rail, that is, parallel to the driving direction X of the vehicle 1. In this case, the mobile battery swap device 108 moves along the extension direction Y of the guide rail so that the mobile battery swap device 108 can install multiple batteries 10 arranged perpendicular to the driving direction X of the vehicle 1.

[0128] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
