[0048] With the development of new energy technologies, more and more devices use batteries. When these devices run out of power, they often need to be recharged by connecting them to charging stations. For example, electric vehicles can be recharged by connecting them to charging stations. However, charging can take a long time, affecting the user experience. Compared to recharging, replacing batteries allows for faster recharging.

[0049] For most vehicles, especially heavy truck chassis battery swaps, the vehicle is too heavy to be lifted up for battery replacement, so trench battery swapping is preferred. When a vehicle enters a battery swap station, the front wheels need to cross the battery swap slot. Related technologies mainly use simple supports placed in the battery swap slot to allow the vehicle to pass through. After the vehicle passes through, the supports placed in the battery swap slot are difficult to move or remove, affecting the disassembly and replacement of the battery.

[0050] In view of this, an embodiment of the present application provides a bridge device and a battery swap station. The bridge device is used to support the vehicle, facilitating the vehicle to enter the battery swap station and replace the battery.

[0051] The bridge device and battery swap station disclosed in the embodiments of this application can be used, but is not limited to, for replacing vehicle batteries. The vehicle 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.

[0052] The following description will be made by taking a vehicle as an example of an electrical device.

[0053] As shown in FIG1 , a vehicle 1 is provided with a battery 100 , which may be provided at the bottom, head, or tail of the vehicle 1 . The battery 100 may be used to power the vehicle 1 , for example, the battery 100 may serve as an operating power source for the vehicle 1 .

[0054] The vehicle 1 may further include a controller 200 and a motor 300 . The controller 200 is used to control the battery 100 to supply power to the motor 300 , for example, to meet the power requirements of the vehicle 1 during startup, navigation, and driving.

[0055] In some embodiments of the present application, the battery 100 can not only serve as the operating power source of the vehicle 1, but also serve 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.

[0056] In some embodiments, the battery 100 can be snap-fitted to the chassis of the vehicle 1 via a snap-fit ​​structure.

[0057] As shown in FIG. 2 , the battery 100 may refer to a single physical module including one or more battery cells 110 to provide higher voltage and capacity.

[0058] In some embodiments, the battery 100 may be a battery pack.

[0059] As an example, the battery 100 includes a case 110 and battery cells 120 , and the battery cells 120 are accommodated in the case 110 .

[0060] The housing 110 may be a component for accommodating the battery cells 120. The housing 110 provides a space for accommodating the battery cells 120, and the housing 110 may have various structures.

[0061] In some embodiments, the housing 110 may include a first housing portion 110a and a second housing portion 110b. The first housing portion 110a and the second housing portion 110b overlap each other, and the first housing portion 110a and the second housing portion 110b together define a storage space for accommodating the battery cells 120. The second housing portion 110b may be a hollow structure with one end open. The first housing portion 110a is a plate-like structure, and the first housing portion 110a overlaps the open side of the second housing portion 110b to form the housing 110 with the storage space. The first housing portion 110a and the second housing portion 110b may also each be a hollow structure with one end open. The open side of the first housing portion 110a overlaps the open side of the second housing portion 110b to form the housing 110 with the storage space. Of course, the first housing portion 110a and the second housing portion 110b may have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0062] Assuming that the first box portion 110 a covers the top of the second box portion 110 b , the first box portion 110 a can also be referred to as an upper box cover, and the second box portion 110 b can also be referred to as a lower box 110 .

[0063] In the battery 100 , there can be one or more battery cells 120 . If there are multiple battery cells 120 , the multiple battery cells 120 can be connected in series, in parallel, or in a hybrid connection. A hybrid connection means that the multiple battery cells 120 are connected in both series and parallel.

[0064] Multiple battery cells 120 can be directly connected in series, in parallel, or mixed together, and then the whole formed by the multiple battery cells 120 can be accommodated in the box 110; of course, multiple battery cells 120 can also be first connected in series, in parallel, or mixed together to form a battery module, and then the multiple battery modules can be connected in series, in parallel, or mixed together to form a whole and accommodated in the box 110.

[0065] As shown in Figures 3 and 4 , a bridge device 400 provided in an embodiment of the present application includes at least one bridge frame 410. The bridge frame 410 includes a support member 10 and a transmission member 20. The support member 10 includes a movable portion 11 and a bearing portion 12 disposed on the movable portion 11. The bearing portion 12 is used to support the vehicle 1. The transmission member 20 includes a guide portion 21 and a transmission portion 22. The guide portion 21 extends along a first direction X. The transmission portion 22 is connected to the support member 10 and cooperates with the guide portion 21 to drive the support member 10 to move along the first direction X.

[0066] The number of bridge frames 410 included in the bridge device 400 can be one, or more than two, for example, two, three, or more. When the bridge device 400 includes two or more bridge frames 410, the two or more bridge frames 410 can be distributed along the second direction Y. Furthermore, when there are two or more bridge frames 410, the two or more bridge frames 410 can have the same dimensions, or they can have different dimensions.

[0067] The load-bearing portion 12 included in the bridge 410 is used to support the vehicle 1 and can be in the form of a plate or a grid formed by multiple connected rods. The movable portion 11 is used to support the load-bearing portion 12, supporting the load-bearing portion 12 at a predetermined height of the battery swap station. The movable portion 11 can be a frame structure, or it can be in the form of support rods.

[0068] The guide portion 21 of the transmission member 20 can be connected to other structures in the battery swap station. The guide portion 21 includes, but is not limited to, a rack, a lead screw, and other structures. The transmission portion 22 can include a gear 221, a nut, and other structures to cooperate with the guide portion 21. The transmission portion 22 can be connected to the movable portion 11 of the support member 10, or alternatively, to the bearing portion 12, ensuring both the installation of the transmission portion 22 and its transmission cooperation with the guide portion 21.

[0069] The transmission cooperation includes but is not limited to gear meshing, screw and nut cooperation, etc., which can enable the transmission part 22 to drive the support member 10 to move as a whole relative to the guide part 21.

[0070] The bridge device 400 provided in the embodiment of the present application includes at least one bridge frame 410. The bridge frame 410 includes a support member 10 and a transmission member 20. The support member 10 includes a movable portion 11 and a load-bearing portion 12. The movable portion 11 is provided to support the load-bearing portion 12 at a predetermined height, thereby providing support for the vehicle 1 when the vehicle 1 passes through the battery swap slot 510 of the battery swap station, preventing the front wheel of the vehicle 1 from falling or getting stuck in the battery swap slot 510, and allowing the vehicle 1 to safely pass through the battery swap slot 510. The corresponding transmission member 20, by having its guide portion 21 extending along the first direction X and the transmission portion 22 connected to the support member 10 and engaging with the guide portion 21, can drive the support member 10 to move along the first direction X. After the front wheel of the vehicle 1 passes through the battery swap slot 510 with the support of the bridge frame 410, the transmission member 20 and the guide portion 21 can cooperate to drive the support member 10 to move, clearing the space in the battery swap slot 510 and facilitating the removal and replacement of the battery 100.

[0071] In some optional embodiments, the bridge device 400 provided in the embodiment of the present application has two or more bridge frames 410 distributed along the second direction Y, and the second direction Y is arranged to intersect with the first direction X.

[0072] The number of bridge frames 410 can be two or three. Of course, it can also be determined based on the size of the battery swap slot 510 and the number of batteries 100 included in the vehicle 1.

[0073] The second direction Y and the first direction X may be perpendicular to each other.

[0074] Since existing vehicles 1 typically include two or more batteries 100, the span size of the battery swap slot 510 in the second direction Y varies depending on the number of batteries 100. By making the bridge device 400 include two or more bridge frames 410 distributed along the second direction Y, it can be adapted to meet the battery 100 replacement needs at a battery swap station under different operating conditions, such as when the vehicle 1 includes one battery 100, two batteries 100, or multiple batteries 100. This system is compatible with battery swapping for different vehicle models, has high compatibility, and improves operational efficiency and asset utilization.

[0075] In some optional embodiments, the bridge device 400 provided in the embodiment of the present application has a width of W1 along the second direction Y of one of the two or more bridge frames 410 , and a width of W2 of one of the bridge frames 410 , where W1=2W2.

[0076] The width of a single bridge frame 410 in the second direction Y can be understood as the width of the supporting portion 12. W2 can be greater than or equal to the width of a battery 100 in the second direction Y.

[0077] For example, taking the bridge device 400 including two bridge frames 410 as an example, for the sake of easy distinction, the two bridge frames 410 may include a first bridge frame 410a and a second bridge frame 410b. Along the second direction Y, the width of the first bridge frame 410a is W1, the width of the second bridge frame 410b is W2, W1=2W2, and the width of W2 is greater than the width of a battery 100.

[0078] As shown in Figures 5 to 7, when vehicle 1 needs to replace three batteries 100, after vehicle 1 enters the station, the support members 10 of the two bridge frames 410 can be controlled by the station control platform to move synchronously to the specified position along the first direction X, and the vehicle 1 moves forward along the second direction Y and crosses the battery exchange slot 510. When the vehicle 1 arrives at the set position, the three batteries 100 to be replaced are just above the two bridge frames 410.

[0079] When preparing for battery swapping, the station control platform controls the support members 10 of the two bridge frames 410 to move along the first direction X to the edge of the battery swap slot 510. At this time, the batteries 100 are moved out of the way, so that the three batteries 100 are suspended in the air, making room for replacing the batteries 100 in the battery swap slot 510. When the battery swap is completed, the support members 10 of the two bridge frames 410 are controlled to move again under the vehicle 1 to facilitate the vehicle 1 to exit the battery swap station.

[0080] As shown in Figures 8 and 9, if two batteries 100 need to be replaced on vehicle 1, the support member 10 of the first cross-bridge 410a can be moved along the first direction X to the edge of the battery swap slot 510. The second cross-bridge 410b is located below the vehicle 1, providing load-bearing space, and the wheels press on the second cross-bridge 410b. When the battery swap is complete, the first cross-bridge 410a is moved along the first direction X to a position flush with the second cross-bridge 410b, making it easier for the vehicle 1 to exit the battery swap station.

[0081] As shown in Figures 10 and 11, when a battery 100 of vehicle 1 needs to be replaced, the support member 10 of the second cross-bridge 410b can be moved along the first direction X to the edge of the battery swap slot 510. The first cross-bridge 410a is located below the vehicle 1, providing load-bearing space, and the wheels press on the first cross-bridge 410a. When the battery swap is complete, the second cross-bridge 410b is moved along the first direction X to a position flush with the first cross-bridge 410a, making it easier for vehicle 1 to exit the battery swap station.

[0082] The bridge device 400 provided in the embodiment of the present application is highly versatile by ensuring that along the second direction Y, the width of one of the two or more bridge frames 410 is W1, and the width of one of the bridge frames 410 is W2, and W1=2W2. This can at least meet the requirements of replacing the corresponding batteries 100 of vehicles 1 including one battery 100, two batteries 100, and three batteries 100.

[0083] It is understood that when the bridge device 400 includes more than two bridge frames 410, the above limitation is only an optional implementation. In some embodiments, it is also possible to make the width of one of the two or more bridge frames 410 along the second direction Y be W1

[0084] In some optional embodiments, the bridge device 400 provided in the embodiment of the present application can also ensure that along the second direction Y, the widths of the two or more bridge frames 410 are equal.

[0085] Taking three bridge frames 410 as an example, the three bridge frames 410 are distributed in the second direction Y and have the same width in the second direction Y.

[0086] When vehicle 1 needs to replace three batteries 100, after vehicle 1 enters the station, the support members 10 of the three bridge frames 410 can be controlled by the station control platform to move synchronously to the specified position along the first direction X, and vehicle 1 moves forward along the second direction Y and crosses the battery exchange slot 510. When vehicle 1 arrives at the set position, the three batteries 100 to be replaced are just above the three bridge frames 410.

[0087] When preparing for battery swapping, the station control platform controls the support members 10 of the three bridge frames 410 to move along the first direction X to the edge of the battery swap slot 510. At this time, the batteries 100 are moved out of the way, so that the three batteries 100 are suspended in the air, making room for replacing the batteries 100 in the battery swap slot 510. When the battery swap is completed, the support members 10 of the three bridge frames 410 are controlled to move again under the vehicle 1 to facilitate the vehicle 1 to exit the battery swap station.

[0088] If two batteries 100 need to be replaced in vehicle 1, the supports 10 of two of the bridges 410 can be moved along the first direction X to the edge of the battery swap slot 510, leaving the remaining bridge 410 below the vehicle 1 to provide load space. When the battery swap is complete, the two bridges 410 in convenient locations are moved along the first direction X to be flush with the other bridge 410, making it easier for vehicle 1 to exit the battery swap station.

[0089] When the vehicle 1 needs to replace a battery 100, the support member 10 of one of the bridge frames 410 can be moved along the first direction X to the edge of the battery exchange slot 510, and the remaining two bridge frames 410 are under the vehicle 1 to provide carrying space. When the battery exchange is completed, the bridge frame 410 at the edge position is moved along the first direction X to a position flush with the other bridge frames 410, so as to facilitate the vehicle 1 to exit the battery exchange station.

[0090] The bridge device 400 provided in the embodiment of the present application has two or more bridge frames 410 with equal widths along the second direction Y. This can also meet the requirements of replacing corresponding batteries 100 for vehicles 1 including one battery 100, two batteries 100, and three batteries 100, thus achieving high versatility.
