Technical Field

[0001] This application relates to the field of battery swapping station technology, and in particular to a battery swapping station. Background Technology

[0002] Energy conservation and emission reduction are crucial for the sustainable development of the automotive industry. In this context, electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the automotive industry's sustainable development. For electric vehicles, battery swapping is an important way to replenish their energy, quickly providing power to vehicles with insufficient power.

[0003] A battery swapping station is a facility that provides rapid battery replacement services for electric vehicles. The size of a battery swapping station has a significant impact on its cost; therefore, how to save space is a problem that needs to be solved in battery swapping technology. Summary of the Invention

[0004] In view of this, embodiments of this application provide a battery swapping station that can save on the area and cost of the battery swapping station.

[0005] This application provides a battery swapping station, comprising: a track extending along a first direction; a bridge device including at least one bridge frame for vehicle wheels to pass through; a battery swapping trolley for transporting batteries, the trolley being able to move along the track; and a lifting device fixed relative to the track, the lifting device including a lifting arm and a lifting drive mechanism, the lifting drive mechanism being used to drive the lifting arm to raise and lower the bridge frame relative to the track, wherein, after being raised, the bridge frame detaches from the track and forms a clearance space between it and the track, allowing the battery swapping trolley to pass through the clearance space.

[0006] The aforementioned battery swapping station includes a track, a bridge device, a battery swapping trolley, and a lifting device. Both the bridge device and the battery swapping trolley can move along the track. The lifting device can precisely control the lifting action of the bridge device, allowing the bridge device to avoid the battery swapping trolley. This eliminates the risk of interference or collision between the battery swapping trolley and the bridge device, and realizes the design of sharing the track between the bridge device and the battery swapping trolley. This saves space in the battery swapping station, reduces the area and cost of the station, and ensures the smooth operation of the battery swapping process by allowing the bridge device to avoid the battery swapping trolley. This improves the battery swapping efficiency and achieves smooth connection and coordinated operation between the bridge device and the battery swapping trolley.

[0007] In some embodiments, the lifting arm extends along a first direction, the bridge can move along the first direction to the lifting device, and the lifting arm can pass through the bridge in the first direction.

[0008] By adopting the above technical solution, the lifting arm can be installed along the first direction through the bridge frame, which is beneficial for the lifting arm to have a larger support area and improves the reliability of the lifting movement of the bridge frame.

[0009] In some embodiments, the bridge frame includes a movable seat and a bridge plate disposed on the movable seat. The movable seat is disposed on the track and is movable along the first direction. The lifting arm is disposed in the movable seat and supported below the bridge plate.

[0010] By adopting the above technical solution, the lifting arm can be inserted into the movable seat, thus improving the connection stability between the lifting arm and the bridge frame.

[0011] In some embodiments, the side of the bridge plate facing the lifting arm is provided with a first positioning part, and the side of the lifting arm facing the bridge plate is provided with a second positioning part, and the first positioning part and the second positioning part can be engaged with each other.

[0012] By adopting the above technical solution, the bridge gantry can move along the track to the lifting device, making operation more convenient; in addition, the lifting arm can position the bridge plate, and the bridge gantry is less likely to sway or shift on the lifting arm, thus improving the reliability of the bridge gantry's lifting movement.

[0013] In some embodiments, one of the first positioning portion and the second positioning portion is a V-shaped protrusion structure, and the other is a V-shaped groove.

[0014] By adopting the above technical solution, on the one hand, the positioning accuracy between the bridge frame and the lifting arm is high, and on the other hand, the swaying during the lifting and lowering process of the bridge frame is reduced.

[0015] In some embodiments, the track includes two guide rails extending along a first direction, the two guide rails being spaced apart along a second direction, the second direction being perpendicular to the first direction and the vertical direction; the orthographic projection of the lifting arm toward the track along the vertical direction falls between the two guide rails.

[0016] By adopting the above technical solution, the lifting arm does not obstruct the operation of the battery swapping trolley and the bridge.

[0017] In some embodiments, there are multiple lifting arms, and the multiple lifting arms are spaced apart along the second direction, and each lifting arm can pass through the movable seat along the first direction.

[0018] By adopting the above technical solutions, multiple lifting arms improve the stability and reliability of the bridge frame movement.

[0019] In some embodiments, the movable seat includes a support frame, and the support frame is provided with rolling components on both sides along the second direction. The lifting device can drive the bridge frame to rise and fall and disengage the rolling components from the guide rail. The rolling components include a traveling wheel and a first guide wheel. The traveling wheel is rotatably disposed on the guide rail and can move on the guide rail along the first direction. The axis of the first guide wheel is parallel to the first direction, and the first guide wheel can roll on the guide rail in the vertical direction.

[0020] By adopting the above technical solution, the support frame can provide stable support for the bridge deck, and the bridge device has good stability and durability; the first guide wheel can guide the lifting and lowering movement of the bridge frame. When the bridge frame falls on the track, the first guide wheel contacts the guide rail and rotates vertically along the side of the guide rail, limiting the horizontal displacement of the bridge frame and making the bridge frame return to its stable position, so that the bridge frame can accurately fall on the track when it descends.

[0021] In some embodiments, the rolling assembly further includes a second guide wheel, the second guide wheel extending axially in a vertical direction, and the second guide wheel being capable of rolling along the side of the guide rail in a first direction.

[0022] By adopting the above technical solution, when the bridge frame moves along the track, the second guide wheel can roll along the side of the guide rail to limit its movement. In this way, the second guide wheel can guide the movement of the bridge frame in the first direction, reducing the risk of deviation or jamming when the bridge frame moves and improving the movement accuracy of the bridge frame.

[0023] In some embodiments, the side of the guide rail is provided with a clearance notch, which is used to avoid the second guide wheel.

[0024] By adopting the above technical solution, the clearance notch on the side of the guide rail can avoid the second guide wheel, prevent the second guide wheel from interfering with the rail, and allow the bridge frame to fall smoothly onto the rail.

The mounting frame is fixedly disposed above the track, the lifting bracket is vertically connected to the lifting arm, and the lifting drive assembly is used to drive the lifting bracket and the lifting arm to lift and lower.

[0026] By adopting the above technical solution, multiple lifting arms can stably support the bridge frame, improving the reliability of the bridge frame's lifting movement.

[0027] In some embodiments, the lifting drive mechanism includes a drive motor fixed on a mounting bracket, a drive shaft connected to the drive motor, and two sets of chain assemblies that are drively connected to the drive shaft. The drive shaft extends along a second direction, and the two sets of chain assemblies are respectively located at opposite ends of the drive shaft along the second direction. The chain mechanism is connected to the lifting bracket, and the drive motor is used to drive the drive shaft to rotate so as to drive the lifting member to rise and fall in the vertical direction through the chain structure. The second direction is perpendicular to the first direction.

[0028] By adopting the above technical solution, the two sets of chain assemblies in the lifting drive mechanism can simultaneously drive the lifting bracket to rise and fall, thereby improving the stability and reliability of the bridge plate during lifting and falling.

[0029] In some embodiments, the mounting bracket is provided with a slide rail extending in a vertical direction, and the lifting bracket is slidably connected to the slide rail.

[0030] By adopting the above technical solution, the slide rail can guide the lifting and lowering movement of the lifting bracket.

[0031] In some embodiments, the bridge crossing device includes at least two bridge crossing frames distributed along a first direction on a track.

[0032] By adopting the above technical solution, at least two bridges can jointly support the vehicle, making it convenient for the vehicle to pass over the battery swapping trough.

[0033] In some embodiments, the bridge crossing device further includes a transmission member, which includes a guide portion and a transmission portion. The guide portion extends along a first direction, and the transmission portion is connected to the movable seat and drives the guide portion to move the movable seat and the bridge plate along the first direction.

[0034] By adopting the above technical solution, the guide and transmission parts work together to automatically drive the bridge frame to move along the track, eliminating the need for manual handling or adjustment of the bridge frame, thus improving the convenience of bridge frame movement and increasing battery swapping efficiency.

[0035] In some embodiments, the guide portion includes a rack extending along the length direction of the guide rail, and the transmission portion includes a gear meshing with the guide portion and a first drive portion connected to the gear.

[0036] By adopting the above technical solution, the transmission unit uses a gear and rack transmission method to drive the bridge frame to move, which can achieve precise movement and has the advantages of high control accuracy and fast response.

[0063] The battery mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.

[0064] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0065] With the development of new energy technologies, more devices are using batteries. When these devices run out of power, they are often recharged by connecting to charging equipment, such as electric vehicles that can be charged at charging stations. Charging takes a long time, affecting the user experience. Compared to charging, replacing the battery provides a much faster way to replenish power.

[0066] A battery swapping station is a facility that provides rapid battery replacement services for electric vehicles. The size of a battery swapping station has a significant impact on its cost; therefore, how to save space is a problem that needs to be solved in battery swapping technology.

[0067] Battery swapping stations typically use swapping carts to transport batteries. However, during battery transport, these carts are prone to interference and collisions with other equipment. To avoid clogging the swapping carts, the working spaces of other equipment need to be staggered from those of the carts, resulting in a larger station area.

[0068] In view of this, the present application provides a battery swapping station, including a track, a battery swapping trolley with a bridge device, and a lifting device. The bridge device includes at least one bridge frame. Both the bridge frame and the battery swapping trolley are capable of moving along the track. The lifting device is capable of supporting the bridge frame and driving the bridge frame to lift and lower. After being lifted, the bridge frame disengages from the track and forms a clearance space between itself and the track.

[0069] In the aforementioned battery swapping station, the bridge-crossing device and the battery swapping trolley share a common track, saving space and reducing the station's area and cost. The lifting device precisely controls the lifting action of the bridge-crossing device, ensuring that it avoids the battery swapping trolley, guaranteeing a smooth battery swapping process, and improving swapping efficiency. Furthermore, because the raised bridge-crossing device avoids the battery swapping trolley, it eliminates the risk of interference or collision between the trolley and the bridge-crossing device, achieving smooth connection and coordinated operation between the bridge-crossing device and the battery swapping trolley. Therefore, the layout of the aforementioned battery swapping station is compact, saving space and reducing the station's area and cost.

[0070] The battery swapping station provided in this application is used to replace batteries for electrical devices, which can be vehicles, especially heavy-duty trucks. Electrical devices can also include, but are not limited to, other electrical equipment such as ships, aircraft, electric toys, power tools, electric vehicles, electric cars, ships, and spacecraft. This application example uses a vehicle as an example for illustration.

[0071] An embodiment of the first aspect of this application provides a battery swapping station. Please refer to... Figures 1 to 4The battery swapping station 100 includes a track 10, a bridge device 20, a battery swapping trolley 40, and a lifting device 30. The track 10 extends along a first direction X. The bridge device 20 includes at least one bridge frame 21, which is mounted on the track 10 and can move along the first direction X. The bridge frame 21 is used for the wheels of the vehicle to pass through. The battery swapping trolley 40 is used to transport batteries and can move along the extension direction of the track 10. The lifting device 30 is fixedly installed relative to the track 10. The lifting device 30 includes a lifting arm 31 and a lifting drive mechanism 32. The lifting drive mechanism 32 is used to drive the lifting arm 31 to lift and lower the bridge frame 21 relative to the track 10. After being lifted, the bridge frame 21 disengages from the track 10 and forms a clearance space 101 between itself and the track 10. The battery swapping trolley 40 can pass through the clearance space 101.

[0072] Figure 1 In the diagram, the first direction X and the second direction Y are both horizontal, and the third direction Z is vertical. The vertical direction is the direction of the object's gravity.

[0073] like Figure 10 As shown, the battery swapping station 100 may include a battery swapping trough 60, with a track 10 disposed within the trough 60. The battery swapping trough 60 may be a trench dug underground; in other embodiments, the battery swapping trough 60 may also be disposed above ground and constructed using equipment.

[0074] like Figure 1 As shown, in some embodiments, track 10 is a straight track extending along a first direction X; in other embodiments, the battery swapping station 100 also includes another track that intersects with and connects to track 10 to meet the needs of the battery swapping trolley 40 for operation.

[0075] The bridge crossing device 20 includes a bridge frame 21 for vehicles to pass over the battery swapping trough 60. After the vehicle passes over the trough 60, with the front and rear wheels of the vehicle on either side of the trough 60, the bridge frame 21 can be moved out from under the vehicle along the track 10 to expose the battery on the vehicle. In some embodiments, the bridge crossing device 20 includes two bridge frames 21, one of which can be lifted by the lifting device 30 to avoid the battery swapping trolley 40. In other embodiments, the bridge crossing device 20 may also include one or more bridge frames 21.

[0076] The battery swapping trolley 40 is used to transport batteries to a location beneath the vehicle. Optionally, the battery swapping trolley 40 is also used for battery replacement, in which case it is equipped with a battery loading / unloading mechanism. The battery swapping trolley 40 can move along the track 10 to transfer batteries between the battery storage device of the battery swapping station 100 and the vehicle. The battery swapping trolley 40 can move on the track 10, or it can travel along the track 10 without contacting it. The battery swapping trolley 40 may include a Railway Guide Vehicle (RGV), and in other embodiments, it may also include an Automated Guided Vehicle (AGV).

[0077] The lifting device 30 is fixedly mounted relative to the track 10. Optionally, the lifting device 30 can be fixedly connected to the beam at the top of the battery swapping station 100, or it can be fixed to the ground on both sides of the battery swapping trough 60. Because the lifting device 30 is fixedly mounted, when the bridge frame 21 moves onto the lifting arm 31 of the lifting device 30, the lifting device 30 can support the bridge frame 21 through the lifting arm 31 and drive the bridge frame 21 to rise and fall relative to the track 10. For example, the lifting device 30 drives the bridge frame 21 vertically (…). Figure 1 The lifting direction of the bridge 21 (in the Z direction) can be understood as the lifting direction of the bridge 21 can also be at a certain angle to the vertical direction.

[0078] The lifting device 30 includes a lifting arm 31 and a lifting drive mechanism 32. The lifting arm 31 can be raised and lowered to avoid the battery swapping trolley 40.

[0079] The lifting arm 31 is used to support the bridge frame 21. The lifting arm 31 can be supported under the bridge plate 212 or on the movable seat 211, as long as the lifting arm 31 can support the entire bridge frame 21.

[0080] The lifting drive mechanism 32 is connected to the lifting arm 31 and is used to drive the lifting arm 31 to rise and fall relative to the track 10, so that the bridge frame 21 is disengaged from the track 10 after being raised and forms a clearance space 101 between the bridge frame 21 and the track 10 for avoiding the battery swapping trolley 40.

[0081] The battery swapping station 100 includes a battery swapping bay, which is a bay where the battery of a vehicle is replaced. A lifting device 30 is located on one side of the battery swapping bay along the first direction X. A bridge frame 21 can support the vehicle at the battery swapping bay, and the bridge frame 21 can move along the first direction X to the lifting device 30, and rise and fall under the action of the lifting device 30.

[0082] The principle of the above-mentioned battery swapping station 100 is as follows:

[0083] When a vehicle needs a battery replacement, the bridge frame 21 is positioned at the battery swapping station to support the vehicle, allowing it to pass through and remain at the station. Then, the bridge frame 21 moves along the first direction X to the lifting device 30. The lifting arm 31 supports the bridge frame 21, and the lifting drive mechanism 32 drives the bridge frame 21 upwards, causing the bridge frame 21 to be spaced apart from the track 10, forming a clearance space 101. Then, as... Figure 3 As shown, the battery swapping trolley 40 carrying a fully charged battery moves to the battery swapping station via the clearance space 101, thereby enabling the vehicle's battery to be replaced. After the battery swap is completed, the battery swapping trolley 40 moves out of the battery swapping station via the clearance space 101, and the lifting drive mechanism 32 drives the bridge frame 21 to descend, so that the bridge frame 21 lands on the track 10. The bridge frame 21 moves to the battery swapping station to prepare to support the next vehicle. This cycle is repeated to complete the battery swapping operation.

[0084] The aforementioned battery swapping station 100 includes a track 10, a bridge device 20, a battery swapping trolley 40, and a lifting device 30. Both the bridge device 20 and the battery swapping trolley 40 can move along the track 10. The lifting device 30 can precisely control the lifting action of the bridge device 21, allowing it to avoid the battery swapping trolley 40. This eliminates the risk of interference or collision between the battery swapping trolley 40 and the bridge device 21, achieving a shared track design for the bridge device 20 and the battery swapping trolley 40. This saves space in the battery swapping station 100, reducing its area and cost. By allowing the bridge device 21 to avoid the battery swapping trolley 40, the battery swapping process is ensured to proceed smoothly, improving swapping efficiency. Furthermore, it achieves smooth connection and coordinated operation between the bridge device 20 and the battery swapping trolley 40. Therefore, the layout of the aforementioned battery swapping station 100 is compact, saving space and reducing its area and cost.

[0085] In some embodiments, the lifting arm 31 extends along a first direction X, the bridge frame 21 can move along the first direction X to the lifting mechanism 30, and the lifting arm 31 can pass through the bridge frame 21 along the first direction X.

[0086] The lifting arm 31 extends along the first direction X, so that the lifting arm 31 can extend along the bridge frame 21 to have a large contact area with the bridge frame 21, which is beneficial for the lifting arm 31 to stably support the bridge frame 21.

[0087] It is understood that the size of the lifting arm 31 along the first direction X can be greater than, less than, or equal to the size of the bridge trolley 21. Optionally, the size of the lifting arm 31 along the first direction X is greater than half the size of the bridge trolley 21, resulting in better support stability. In addition, since the lifting arm 31 extends along the first direction X and the bridge trolley 21 moves along the first direction X, the bridge trolley 21 can move onto the lifting arm 31 simply by moving along the first direction X. The lifting arm 31 only needs to move up and down and does not need to move horizontally relative to the track 10 to avoid the bridge trolley 21 or the battery swapping trolley 40. Furthermore, the lifting arm 31 will not obstruct the movement of the bridge trolley 21 along the track 10.

[0088] By adopting the above technical solution, the lifting arm 31 can be installed along the first direction X through the bridge frame 21, which is beneficial for the lifting arm 31 to have a larger support area and improve the reliability of the lifting movement of the bridge frame 21.

[0089] Please refer to Figures 3 to 5 In some embodiments, the bridge frame 21 includes a movable seat 211 and a bridge plate 212 disposed on the movable seat 211. The movable seat 211 is disposed on the track 10 and can move along the first direction X. The bridge plate 212 is used to support the vehicle. The lifting arm 31 can pass through the movable seat 211 and be supported under the bridge plate 212.

[0090] Since the lifting arm 31 extends along the first direction X, the bridge frame 21 can move along the first direction X to the lifting arm 31. The lifting arm 31 can be inserted into the movable seat 211, thus the connection stability between the lifting arm 31 and the bridge frame 21 is good.

[0091] For example, the movable seat 211 includes a support frame 2111 and a rolling assembly 2112 disposed at the bottom of the support frame 2111. The support frame 2111 has a hollow portion, through which the lifting arm 31 can pass. Thus, the lifting arm 31 can directly contact the bridge plate 212 and be supported under the bridge plate 212. The bridge plate 212 is not limited to being plate-shaped; it may also include mounting members or mounting frames connected to the support frame 2111.

[0092] In other embodiments, the lifting arm 31 may also be inserted into the gap between the support frame 2111 and the rolling assembly 2112, or the moving seat 211 may have a through hole through which the lifting arm 31 can pass.

[0093] By adopting the above technical solution, the lifting arm 31 can be inserted into the movable seat 211, thereby improving the connection stability between the lifting arm 31 and the bridge frame 21.

[0094] In some embodiments, the lifting arm 31 can pass through the support frame 2111 and be supported under the bridge plate 212. The bridge plate 212 is provided with a first positioning part 2121 on the side facing the lifting arm 31, and the lifting arm 31 is provided with a second positioning part 311 on the side facing the bridge plate 212. The first positioning part 2121 and the second positioning part 311 are engaged.

[0095] The bridge plate 212 is provided with a first positioning part 2121 on the side facing the lifting arm 31, and the lifting arm 31 is provided with a second positioning part 311 on the first side facing the bridge plate 212. The first positioning part 2121 and the second positioning part 311 are interlocked with each other. In this way, when the lifting arm 31 supports the bridge plate 212, the bridge plate 212 is not easy to shake or shift on the lifting arm 31.

[0096] Optionally, when there are multiple lifting arms 31, one or more lifting arms 31 are provided with a second positioning part 311.

[0097] Since at least a portion of the bridge frame 21 is located in the battery swapping trough, the lifting arm 31 can also be located in the battery swapping trough for convenient operation. When the bridge frame 21 moves along the track 10 to the lifting device 30, the lifting arm 31 can pass through the support frame 2111 and be located below the bridge plate 212; the lifting drive mechanism 32 drives the lifting arm 31 to rise, so that the second positioning part 311 engages with the first positioning part 2121, and the lifting drive mechanism 32 continues to drive the lifting arm 31 to rise until a sufficient clearance space 101 is formed between the bridge frame 21 and the track 10.

[0098] By adopting the above technical solution, the bridge frame 21 can move along the track 10 to the lifting device 30, and the lifting arm 31 passes through the support frame 2111 and is located below the bridge plate 212, making operation more convenient. In addition, by setting the first positioning part 2121 and the second positioning part 311 that are interlocked, the lifting arm 31 can position the bridge plate 212, and the bridge frame 21 is less likely to shake or shift on the lifting arm 31, thus improving the reliability of the lifting movement of the bridge frame 21.

[0099] In some embodiments, one of the first positioning part 2121 and the second positioning part 311 is a V-shaped protrusion structure, and the other is a V-shaped groove.

[0100] Optionally, the bridge plate 212 can be a steel plate structure, and the first positioning part 2121 is a V-shaped angle steel located at the bottom of the bridge plate 212. Angle steel is a long strip of steel, and V-shaped angle steel refers to a long strip of steel with a V-shaped cross-section. It can be understood that the material of the V-shaped protrusion structure is not limited to steel. For example, the V-shaped protrusion structure can also be made of plastic or other metal materials.

[0101] Correspondingly, the second positioning part 311 is a V-shaped groove. For ease of installation, a positioning block protrudes from the lifting arm 31, and the V-shaped groove is formed on the surface of the positioning block. Of course, the V-shaped groove can also be recessed into the surface of the lifting arm 31.

[0102] By adopting the above technical solution, both the first positioning part 2121 and the second positioning part 311 are V-shaped. The first positioning part 2121 and the second positioning part 311 can automatically align during the snap-fit ​​process, and the first positioning part 2121 and the second positioning part 311 can be snapped together stably. On the one hand, the positioning accuracy between the bridge frame 21 and the lifting arm 31 is high, and on the other hand, the swaying during the lifting and lowering movement of the bridge frame 21 is reduced.

[0103] Optionally, the lifting arm is also equipped with a buffer pad 312, which can buffer the bridge plate 212.

[0104] Please refer to Figure 1 , Figure 4 and 6 In some embodiments, the track 10 includes two guide rails 11 extending along a first direction X, the two guide rails 11 being spaced apart along a second direction Y perpendicular to the first direction X and the vertical direction; the orthographic projection of the lifting arm 31 along the vertical direction toward the track 10 falls between the two guide rails 21.

[0105] The track 10 includes two guide rails 11, which may be, but are not limited to, I-shaped. The bridge frame 21 spans the two guide rails 11 and is movably connected to the guide rails 11.

[0106] The vertical projection of the lifting arm 31 onto the track 10 falls between the two guide rails 21, meaning the projection of the lifting arm 31 will not fall on the guide rails 21. In this way, the lifting arm 31 can avoid the battery swapping trolley and the bridge 21 by raising and lowering, and the lifting arm 31 does not obstruct the operation of the battery swapping trolley and the bridge 21.

[0107] Please refer to Figure 1 , Figure 7 and Figure 8 In some embodiments, there are multiple lifting arms 31, and the multiple lifting arms 31 are spaced apart along the second direction Y, and each lifting arm 31 can be inserted into the movable seat along the first direction.

[0108] For example, there are three lifting arms 31 along the second direction Y, and the three lifting arms 31 can support the middle and both sides of the bridge frame 21.

[0109] By setting up multiple lifting arms 31, the multiple lifting arms 31 can stably support the bridge frame 21, thereby improving the reliability of the lifting and lowering movement of the bridge frame 21.

[0110] In other embodiments, the lifting arm 31 may also be a single arm and the lifting arm 31 may be flat.

[0111] In some embodiments, the movable seat 211 includes a support frame 2111, and the support frame 2111 is provided with rolling components 2112 on both sides along the second direction Y. The lifting device 30 can drive the bridge frame 21 to rise and fall and cause the rolling components 2112 to disengage from the guide rail 11. The rolling components 2112 include a traveling wheel 2113 and a first guide wheel 2114. The traveling wheel 2113 is rotatably disposed on the guide rail 11 and can move on the guide rail 11 along the first direction X. The axis of the first guide wheel 2114 is parallel to the first direction X, and the first guide wheel 2114 can roll on the guide rail 11 in the vertical direction.

[0112] The movable seat 211 includes a support frame 2111 and a rolling assembly 2112 disposed at the bottom of the support frame 2111. The support frame 2111 may be, but is not limited to, a hollow frame. The rolling assembly 2112 can move along the guide rail 11 to drive the movable seat 211 and the bridge plate 212 to move along the track 10. Optionally, two sets of rolling assemblies 2112 are respectively provided on both sides of the movable seat 211 along the second direction Y to improve the stability of the movement.

[0113] The lifting device 30 can drive the bridge frame 21 to rise and fall and cause the rolling assembly 2112 to disengage from the guide rail 11. The rolling assembly 2112 includes a traveling wheel 2113 and a first guide wheel 2114. The traveling wheel 2113 can move along the guide rail 11. The axis of the first guide wheel 2114 is parallel to the first direction X, so the first guide wheel 2114 can rotate around an axis parallel to the first direction X. When the bridge frame 21 descends, the first guide wheel 2114 rolls on the guide rail 11 in the vertical direction. The two first guide wheels 2114 arranged along the second direction Y of the support frame 2111 simultaneously guide the rise and fall of the support frame 2111.

[0114] Optionally, the height of the first guide wheel 2114 is lower than the height of the traveling wheel 2113, so that when the bridge frame 21 descends, the first guide wheel 2114 contacts the guide rail 11 before the traveling wheel 2113. The first guide wheel 2114 can be mounted on the bottom of the support frame 2111 via an adapter 2116, on which the first guide wheel 2114 is rotatably mounted. One end of the adapter 2116 is fixedly connected to the support frame 2111, and the other end extends toward the guide rail 11. The end of the adapter 2116 on which the first guide wheel 2114 is mounted can be bent toward the guide rail 11.

[0115] Optionally, the first guide wheel 2114 is located on the outside of the support frame 2111, that is, the first guide wheels 2114 on both sides of the support frame 2111 are located outside the track 10; in other embodiments, the first guide wheel 2114 may also be located on the inside of the guide rail 11.

[0116] By adopting the above technical solution, the movable seat 211 includes a support frame 2111 and a rolling assembly 2112. The support frame 2111 can provide stable support for the bridge plate 212, and the bridge device 20 has good stability and durability. The rolling assembly 2112 includes a traveling wheel 2113 and a first guide wheel 2114. The first guide wheel 2114 can guide the lifting and lowering movement of the bridge frame 21. When the bridge frame 21 falls on the track 10, the first guide wheel 2114 contacts the guide rail 11 and rotates vertically along the side of the guide rail 11, limiting the horizontal displacement of the bridge frame 21, so that the bridge frame 21 returns to its stable position, and thus the bridge frame 21 can accurately fall on the track 10 when it descends.

[0117] Please continue to refer to Figure 1 , Figure 4 and 6 In some embodiments, the rolling assembly 2112 further includes a second guide wheel 2115, the second guide wheel 2115 extending axially in a vertical direction, and the second guide wheel 2115 being able to roll on the side of the guide rail 11 in a first direction X.

[0118] The second guide wheel 2115 is rotatably connected to the support frame 2111. The second guide wheel 2115 can rotate around the vertical direction (third direction Z). When the traveling wheel 2113 moves on the guide rail 11, the second guide wheel 2115 can roll along the side of the guide rail 11 to guide the movement of the bridge frame 21 along the first direction X.

[0119] Optionally, the height of the second guide wheel 2115 is lower than the height of the traveling wheel 2113.

[0120] Optionally, the support frame 2111 is provided with at least one pair of second guide wheels 2115 on each side along the second direction Y. The two second guide wheels 2115 are respectively provided on opposite sides of the guide rail 11 along the second direction Y, which further improves the guiding effect.

[0121] By adopting the above technical solution, when the bridge frame 21 moves along the track 10, the second guide wheel 2115 can roll along the side of the guide rail 11 to limit the movement. Thus, the second guide wheel 2115 can guide the movement of the bridge frame 21 along the first direction X, reducing the risk of the bridge frame 21 deviating or getting stuck when it moves, and improving the movement accuracy of the bridge frame 21.

[0122] like Figure 6 As shown, in some embodiments, the side of the guide rail 11 is provided with a clearance notch 111, which is used to avoid the second guide wheel 2115.

[0123] Since the bridge frame 21 is raised and lowered at the lifting device 30, the clearance notch 111 is also located at the lifting device 30. The clearance notch 111 can be arc-shaped, so that the clearance notch 111 can fit against the second guide wheel 2115. Of course, the clearance notch 111 can also be other shapes, as long as it can avoid the second guide wheel 2115.

[0124] When the bridge frame 21 descends under the drive of the lifting device 30, the clearance notch 111 on the side of the guide rail 11 can avoid the second guide wheel 2115, thus preventing the second guide wheel 2115 from interfering with the track 10, and allowing the bridge frame 21 to fall smoothly onto the track 10.

[0125] Please refer to Figure 1 , Figures 7 to 9 In some embodiments, the lifting drive mechanism 32 includes a mounting frame 321, a lifting drive assembly 322 disposed on the mounting frame 321, and a lifting bracket 323 connected to the lifting drive assembly 322. The mounting frame 321 is fixedly disposed above the track 10, the lifting bracket 323 is vertically connected to the lifting arm 31, and the lifting drive assembly 322 is used to drive the lifting bracket 323 and the lifting arm 31 to rise and fall.

[0126] Mounting bracket 321 is used to mount lifting drive assembly 322 and lifting bracket 323. Mounting bracket 321 is located above track 10 and does not obstruct the movement of bridge frame 21 and battery swapping trolley 40 on track 10.

[0127] The lifting drive assembly 322 is used to drive the lifting bracket 323 to rise and fall. The lifting drive assembly 322 may include drive components such as a motor, cylinder, and ball screw. The lifting arm 31 extends along a first direction X, and the lifting bracket 323 is vertically connected to the lifting arm 31, that is, the lifting bracket 323 is arranged in a vertical direction. When there are multiple lifting arms 31, all of the lifting arms 31 are connected to the lifting bracket 323. The lifting arm 31 and the lifting bracket 323 can be integrally set or fixedly connected by welding or other methods.

[0128] By adopting the above technical solution, the lifting drive mechanism 32 is fixed above the track 10, and the lifting drive assembly 322 can drive the lifting bracket 323 and the lifting arm 31 to rise and fall, thereby the lifting drive mechanism 32 drives the bridge frame 21 to rise and fall; the lifting bracket 323 is connected between the lifting drive assembly 322 and the lifting arm 31, so the lifting arm 31 can be configured as a support arm extending along the first direction X.

[0129] In some embodiments, the lifting drive assembly 322 includes a drive motor 3221 fixed on the mounting bracket 321, a drive shaft 3222 connected to the drive motor 3221, and two sets of chain assemblies 3223 that are drively connected to the drive shaft 3222. The drive shaft 3222 extends along the second direction Y, and the two sets of chain assemblies 3223 are respectively disposed at opposite ends of the drive shaft 3222 along the second direction Y. The chain assemblies 3223 are connected to the lifting bracket 323, and the drive motor 3221 is used to drive the drive shaft 3222 to rotate, so as to drive the lifting bracket 323 to rise and fall in the vertical direction through the chain assemblies 3223.

[0130] The drive shaft 3222 extends along the second direction Y, that is, the drive shaft 3222 extends along the width direction of the track 10, and the drive motor 3221 can drive the drive shaft 3222 to rotate.

[0131] The chain assembly 3223 includes two sprockets arranged opposite each other in a vertical direction and a chain connected to the two sprockets. The lifting bracket 323 is fixedly connected to the chain and can move with the chain. One of the sprockets is connected to the drive shaft 3222. The two sets of chain assemblies 3223 are respectively located at both ends of the drive shaft 3222 along the second direction Y. Thus, the drive shaft 3222 can simultaneously drive the chains in the two sets of chain assemblies 3223 to move. The two sets of chain assemblies 3223 are respectively connected to both ends of the lifting bracket 323, which can smoothly drive the lifting bracket 323 to rise and fall.

[0132] By adopting the above technical solution, the two sets of chain assemblies 3223 in the lifting drive mechanism 32 can simultaneously drive the lifting bracket 323 to rise and fall, thereby improving the stability and reliability of the bridge plate 212 during lifting and falling.

[0133] In some embodiments, the mounting bracket 321 is provided with a slide rail 3211 extending in a vertical direction, and the lifting bracket 323 is slidably connected to the slide rail 3211.

[0134] The slide rail 3211 can guide the lifting movement of the lifting bracket 323, improve the movement accuracy of the lifting bracket 323, lifting arm 31 and bridge frame 21 during the lifting process, and help the bridge frame 21 to fall accurately on the track 10 after it descends.

[0135] Please refer to Figure 1 In some embodiments, the bridge crossing device 20 includes at least two bridge crossing frames 21, which are distributed along a first direction X on the track 10.

[0136] For example, the bridge device 20 includes two bridge frames 21 distributed along a first direction X. The two bridge frames 21 can be brought close together to jointly support the vehicle, and the two bridge frames 21 can be moved away from each other to expose the vehicle's battery. The lifting device 30 is connected to one of the bridge frames 21.

[0137] By adopting the above technical solution, at least two bridges 21 can jointly support the vehicle, making it convenient for the vehicle to pass over the battery swapping trough.

[0138] In some embodiments, the battery swapping vehicle 40 includes an RGV vehicle.

[0139] The RGV vehicle is mounted on track 10 and can move along track 10. This embodiment of the application realizes a shared track design for the RGV vehicle and the bridge 21, which helps to reduce the space of the battery swapping station 100. Optionally, the battery swapping trolley 40 also includes a battery unlocking mechanism mounted on the RGV vehicle, which can automatically replace the battery of the vehicle.

[0140] In some embodiments, the battery swapping station 100 further includes a wheel track adjustment mechanism 50. The wheel track adjustment mechanism 50 is connected to the bridge frame 21 and can be adjusted according to the wheel track of the vehicle so that the vehicle's wheels can be accurately placed on the bridge frame 21.

[0141] In some embodiments, the bridge crossing device 20 further includes a transmission member 22, which includes a guide portion 221 and a transmission portion 222. The guide portion 221 extends along a first direction X, and the transmission portion 222 is connected to the movable seat 211 and engages with the guide portion 221 in a transmission manner to drive the movable seat 211 and the bridge crossing plate 212 to move along the first direction X.

[0142] The transmission component 22 is a structure used to drive the bridge frame 21 to move along the track 10. The guide part 221 may include, but is not limited to, a rack and pinion, a lead screw, etc., and the transmission part 222 may include, but is not limited to, a gear, a lead screw nut, etc., as long as the transmission part 222 and the guide part 221 are in transmission engagement. The transmission engagement includes, but is not limited to, gear meshing, lead screw and lead screw nut engagement, etc., so that the transmission part 222 can drive the bridge frame 21 to move relative to the guide part 221. The transmission part 222 can be connected to the support frame 2111.

[0143] By adopting the above technical solution, the guide unit 221 and the transmission unit 222 work together to automatically drive the bridge frame 21 to move along the track 10 without manual handling or adjustment of the bridge frame 21, which improves the convenience of moving the bridge frame 21 and increases the battery swapping efficiency.

[0144] In some embodiments, the guide portion 221 includes a rack extending along a first direction X, and the transmission portion 222 includes a gear meshing with the guide portion 221 and a first drive portion connected to the gear.

[0145] The first drive unit may include a motor for driving the gear to rotate. The first drive unit drives the gear to rotate, causing the gear to move along the rack, thereby driving the bridge frame 21 to move along the track 10.

[0146] By adopting the above technical solution, the transmission unit 222 drives the bridge frame 21 to move by means of gear and rack transmission, which can achieve precise movement and has the advantages of high control accuracy and fast response.

[0147] Please refer to Figure 1 and Figure 10 In some embodiments, the battery swapping station 100 is provided with a battery swapping trough 60, the track 10, the movable seat 211 of the bridge frame 21 and the battery swapping trolley 40 are provided in the battery swapping trough 60, and the lifting device 30 is provided above the battery swapping trough 60 and the lifting arm 31 can be lowered into the battery swapping trough 60.

[0148] The battery swapping station 100 provided in this embodiment includes a battery swapping trough 60, which can be a trench. A track 10 is disposed in the battery swapping trough 60, and the movable seat 211 of the bridge frame 21 and the battery swapping trolley 40 move within the battery swapping trough 60. A bridge plate 22 can be disposed on the ground to allow vehicles to pass through the battery swapping trough 60.

[0149] By setting up the bridge device 20, vehicles can pass through the battery swapping trough 60. By setting up the battery swapping trolley 40, the battery can be automatically transported to the area under the vehicle. Furthermore, by setting up the lifting device 30, the bridge frame 21 can be lifted to avoid the battery swapping trolley 40. The lifting arm 31 can be lowered into the battery swapping trough 60, so the bridge frame 21 can move along the first direction X onto the lifting arm 31, which is easy to implement. The lifting arm 31 can provide sufficient support area and support force for the bridge frame 21.

[0150] The battery swapping station 100 also includes a battery rack for storing multiple batteries, and the battery swapping trolley 40 moves between the battery rack and the bridge device 20.

[0151] In some embodiments, the battery swapping station 100 may be a heavy-duty truck battery swapping station.

[0152] The battery swapping station 100 is used to replace batteries for heavy-duty trucks. The batteries of heavy-duty trucks are located on the chassis. Due to the weight of heavy-duty trucks, it is not suitable to elevate the vehicle for battery replacement; instead, a trench-based battery swapping method is more appropriate. The battery swapping station 100 provided in this embodiment can be equipped with a trench (battery swapping trough 60) to accommodate the track 10.

[0153] The battery swapping station 100 provided in this application embodiment can be a heavy-duty truck battery swapping station, which can meet the needs of battery swapping for heavy-duty truck chassis and saves the area of ​​the battery swapping station 100.

The battery swapping trolley 40 can move along the track 10. The lifting device 30 includes a lifting arm 31 and a lifting drive mechanism 32. The lifting arm 31 extends along the first direction X and is used to support the bridge frame 21. The lifting drive mechanism 32 is used to drive the lifting arm 31 to raise and lower the bridge frame 21 relative to the track 10. After the bridge frame 21 is raised, it disengages from the track 10 and forms a clearance space 101 between itself and the track 10. The battery swapping trolley 40 can pass through the clearance space 101. The movable seat 211 includes a support frame 2111, with rolling components 2112 respectively provided on both sides of the support frame 2111 along the second direction Y.
