The casters are located at the bottom of the side frame portions.

[0007] The lifting fixture includes a lifting frame and a lifting tool. The lifting frame is fixedly connected to the load-bearing frame, and the lifting tool is connected to the lifting frame and used to suspend the battery. Along the first direction, the lifting frame is located between two side frames.

[0008] The battery transfer device provided in this application includes a main frame and a lifting fixture. The lifting fixture includes a lifting frame and a lifting tool. The lifting fixture is fixed to the main frame via the lifting frame and the battery is lifted by the lifting tool. The main frame includes a load-bearing frame and casters. The load-bearing frame can support the lifting fixture and the battery, and the casters allow the battery transfer device to move easily and flexibly. The lifting frame is located between two side frames, which protect the battery and reduce the risk of collision. This battery transfer device can lift batteries and allow for manual movement, enabling rapid battery handling by manpower. This solves the problem of difficult battery handling. Furthermore, the device is easy to operate manually and is less likely to damage the battery. Therefore, this battery transfer device effectively reduces the risk of battery damage associated with forklifts and other transfer devices, and its operation is relatively safe with minimal safety risks to personnel.

[0009] In some embodiments, along the second direction, the two ends of the hoisting frame extend beyond the main frame, and the second direction is perpendicular to the first direction and the vertical direction.

[0010] By adopting the above technical solution, the size of the main frame along the second direction is smaller than that of the hoisting frame, which helps to reduce the weight of the main frame and facilitates the movement of the battery transfer device.

[0011] In some embodiments, the side frame includes a support portion and a caster mounting member. The two ends of the support portion in the vertical direction are respectively connected to the top frame portion and the caster mounting member, and a plurality of casters are connected to the caster mounting member.

[0012] By adopting the above technical solution, the caster mounting component can accommodate more casters and improve the stability of the main frame.

[0013] In some embodiments, in each side frame portion, the dimension of the caster mount in the second direction is greater than the dimension of the support portion in the second direction, and the two ends of the caster mount in the second direction extend beyond the support portion.

[0014] By adopting the above technical solution, the size of the caster mounting part along the second direction is larger than the size of the support part, which reduces the risk of the main frame tipping over and improves the mobility of the battery transfer device.

The first reinforcing rod and the second reinforcing rod are fixedly connected by a fixing assembly so that the hoisting frame is fixedly connected to the load-bearing frame.

[0020] By adopting the above technical solution, it is convenient to install and disassemble the hoisting fixtures, and the connection between the hoisting frame and the main frame has good reliability.

[0021] In some embodiments, the lifting frame is provided with lifting devices on both sides along the first direction. The lifting devices include flexible slings, mounting frames, and battery connectors provided on the mounting frames. The flexible slings are connected between the lifting frame and the mounting frames, and the battery connectors are used to connect batteries.

[0022] By adopting the above technical solution, the lifting devices on both sides of the battery transfer device can lift the battery together. By setting up movable flexible slings, the lifting devices can be adaptively adjusted, so that the lifting devices can be accurately connected to the battery and lift the battery.

[0023] In some embodiments, the end of the mounting bracket away from the flexible sling is provided with a retaining portion for retaining the battery in a retaining hole.

[0024] By adopting the above technical solution, the lifting device can fix the battery through the clamping part, and the lifting devices on both sides of the battery transfer device can lift the battery together, resulting in good stability.

[0025] In some embodiments, the mounting bracket is provided with a threaded hole extending in a first direction, a battery connector passes through the threaded hole and is threadedly connected to the threaded hole, and the battery connector is used to hold the battery; at least two lifting devices are arranged opposite each other in the first direction and jointly clamp the battery through the battery connector.

[0026] By adopting the above technical solution, the lifting devices on both sides of the battery transfer device jointly clamp the battery through battery connectors, which improves the reliability of the battery lifting process.

[0027] In some embodiments, the lifting device further includes a limiting member and a locking pin. The limiting member is fixedly connected to the mounting bracket, and the locking pin and the limiting member are respectively disposed on opposite sides of the battery connector. The locking pin is used to fix the battery connector on the limiting member.

[0028] By adopting the above technical solutions, the risk of battery connectors becoming loose or falling off is reduced, thereby reducing the risk of the battery falling off and improving the reliability of battery hoisting.

[0029] In some embodiments, the lifting frame is provided with a detachable sling fixing block, and the sling fixing block has an installation hole, through which a flexible sling is inserted.

[0030] By adopting the above technical solution, the risk of displacement during battery hoisting with flexible slings is reduced; the sling fixing blocks are detachable, so the installation position of the sling fixing blocks can be easily changed on the hoisting frame, and the hoisting tools can be easily maintained and replaced.

[0031] In some embodiments, the casters are swivel wheels.

[0032] By adopting the above technical solution, the casters can rotate flexibly, improving the mobility of the battery transfer device and making it convenient to use the battery transfer device to transport batteries.

[0033] In some embodiments, the lifting frame is provided with lifting rings.

[0034] By adopting the above technical solution, the hoisting fixtures can be lifted by hoisting equipment, making it convenient to assemble the hoisting fixtures onto the main frame and saving manpower.

[0062] 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.

[0063] For electric vehicles, battery swapping is an important way to replenish energy, as it can quickly replenish the energy of electric vehicles that are low on power.

[0064] A battery swapping station is a facility that provides rapid battery replacement services for electric vehicles. In a battery swapping station, transfer devices are used to move the batteries, including the entry and exit of batteries from the swapping station's battery compartment. Battery entry refers to the battery moving into the swapping station, and battery exit refers to the battery being transferred outside the swapping station. For example, batteries requiring repair may be moved outside the swapping station, or repaired batteries or new batteries may be delivered into the battery compartment of the swapping station via transfer devices.

[0065] Due to their weight, batteries are difficult to handle directly. Currently, forklifts and slings are commonly used as transfer devices. The slings are used to lift the batteries onto the forklift, which then transports them. However, during battery transfer, the batteries are prone to shaking, posing a significant risk of damage from impacts and other impacts, thus requiring skilled forklift operators. To reduce the risk of battery damage, manual intervention is needed to straighten the batteries, which also presents safety risks to personnel.

[0066] To address the issue of battery damage caused by transfer devices, this application provides a battery transfer device, including a main frame and a lifting fixture. The main frame includes a support frame and casters connected to the bottom of the support frame. The support frame includes two side frames arranged opposite each other along a first direction and a top frame connected between the two side frames. The lifting fixture includes a lifting frame and a lifting device. The lifting frame is fixedly connected to the support frame, and the lifting device is connected to the lifting frame and used to suspend the battery. Along the first direction, the lifting frame is located between the two side frames.

[0067] The battery transfer device provided in this application includes a main frame and a lifting fixture. The lifting fixture can lift the battery, and the casters on the main frame are movable, allowing the battery transfer device to be easily moved manually. This battery transfer device can lift the battery and enable manual movement, allowing for quick battery handling by manpower, solving the problem of difficult battery handling. Furthermore, the device is easy to operate manually and is less likely to damage the battery. Simultaneously, the lifting frame is located between two side frames, which protect the battery and further reduce the risk of collision. Therefore, this battery transfer device effectively reduces the risk of battery damage associated with forklifts and other transfer devices, while also being relatively safe to use and posing minimal safety risks to personnel.

[0068] The battery transfer device provided in this application embodiment is used to transfer batteries. The battery transfer device and battery swapping station provided in this application embodiment can be used, but are not limited to, to replace the batteries of vehicles. They can also be used to replace the batteries of other electrical equipment such as ships, aircraft, electric toys, power tools, electric vehicles, electric cars, ships, and spacecraft.

[0069] The battery transfer device provided in this application can be used not only in battery swapping stations, but also in other scenarios where batteries need to be transferred, such as in battery production workshops.

[0070] An embodiment of the first aspect of this application provides a battery transfer device. Please refer to... Figures 1 to 4 The battery transfer device 100 includes a main frame 10 and a lifting fixture 20. The main frame 10 includes a load-bearing frame 11 and casters 12. The load-bearing frame includes two side frame portions 111 arranged opposite each other along the first direction X and a top frame portion 112 connected between the two side frame portions 111. The casters 12 are located at the bottom of the side frame portions 111. The lifting fixture 20 includes a lifting frame 21 and a lifting device 22. The lifting frame 21 is fixedly connected to the load-bearing frame 11. The lifting device 22 is connected to the lifting frame 21 and is used to suspend the battery 200. Along the first direction X, the lifting frame is located between the two side frame portions.

[0071] The main frame 10 includes a load-bearing frame 11 and casters 12. The load-bearing frame 11 is used to support the hoisting fixture 20 and the battery 200 connected to the hoisting fixture 20. The shape of the load-bearing frame 11 can be rectangular, U-shaped or other shapes. The material of the load-bearing frame 11 can be steel, aluminum, wood, composite materials or the like.

[0072] Casters 12 are located at the bottom of the side frame 111. There can be one or more casters 12, and the casters 12 can be swivel casters, fixed casters, or other types. By providing casters 12, the battery transfer device 100 can be moved conveniently and flexibly.

[0073] The lifting fixture 20 is used to fix and move the battery 200. The lifting fixture 20 includes a lifting frame 21 and a lifting tool 22. The lifting frame 21 is fixedly connected to the supporting frame 11, so that the lifting fixture 20 is fixed on the main frame 10. The lifting frame 21 can be a square frame, a round frame, etc., and the material of the lifting frame 21 can be steel, aluminum, wood, composite materials, etc. The lifting tool 22 is a tool used to suspend and fix the battery 200. The lifting tool 22 can be of various types; for example, the lifting tool 22 fixes the battery 200 by clamping or holding.

[0074] The battery transfer device 100 can be used in battery swapping stations to transfer batteries 200. In particular, the battery transfer device 100 can be used in heavy truck battery swapping stations to transfer heavier batteries 200.

[0075] When transferring battery 200, the battery 200 is fixed and lifted by the lifting tool 22, so that the battery 200 is hoisted on the lifting tool 20. Then, the main frame 10 is pushed manually, and the battery transfer device 100 is moved through the casters 12, so that the battery 200 can be moved and transported.

[0076] The battery transfer device 100 provided in this application embodiment includes a main frame 10 and a lifting fixture 20. The lifting fixture 20 includes a lifting frame 21 and a lifting tool 22. The lifting fixture 20 is fixed to the main frame 10 by the lifting frame 21 and lifts the battery 200 by the lifting tool 22. The main frame 10 includes a load-bearing frame 11 and casters 12. The load-bearing frame 11 can support the lifting fixture 20 and the battery 200, and the casters 12 allow the battery transfer device 100 to move conveniently and flexibly. The battery transfer device 100 can lift the battery 200 and enable manual movement, allowing for quick and manual handling of the battery 200, solving the problem of difficult operation when handling the battery 200. Furthermore, the battery transfer device 100 is easy to operate manually and is less likely to damage the battery 200. Therefore, the battery transfer device 100 effectively reduces the risk of damage to the battery 200 associated with forklifts and other transfer devices, while also being safer to use and posing less safety risk to personnel.

[0077] The battery transfer device 100 provided in this application embodiment can be used in battery swapping stations, such as heavy-duty truck battery swapping stations. Because the battery transfer device 100 can be manually pushed, it is small in size and easy to move, and can adapt to the spatial layout of battery swapping stations.

[0078] like Figures 1 to 4 As shown, the first direction X and the second direction Y are both horizontal, and the third direction Z is vertical. The vertical direction is the same as the direction of gravity, that is, the direction in which the object falls freely.

[0079] The side frame portion 111 is located on the side of the supporting frame 11, and the top frame portion 112 is located on the top of the supporting frame 11. The two side frame portions 111 are arranged opposite each other along a first direction X. Optionally, the first direction X is the width direction of the battery 200, and the second direction Y is the length direction of the battery 200. The two side frame portions 111 can protect the battery 200 along the width direction of the battery 200. For example, the side frame portion 111 extends along a third direction Z, and the top frame portion 112 is arranged horizontally. It can be understood that the side frame portion 111 can also be tilted at a certain angle relative to the third direction Z, and the top frame portion 112 can also be tilted at a certain angle relative to the horizontal direction. The side frame portion 111 and the top frame portion 112 can be integrally formed, or they can be fixedly connected by welding or other methods.

[0080] In some embodiments, the connection between the side frame portion 111 and the top frame portion 112 is arc-shaped. It can be understood that the connection between the side frame portion 111 and the top frame portion 112 may also be sharp-angled.

[0081] Each side frame 111 is provided with a caster 12 at its bottom. For example, each side frame 111 is provided with three casters 12 at its bottom. It can be understood that the number of casters 12 can be set to one or more as needed.

[0082] The lifting frame 21 can be fixedly connected to the top frame 112 or to the two side frames 111. Along the first direction X, the lifting frame 21 is located between the two side frames 111. Since the lifting device 22 is connected to the lifting frame 21, it is also located between the two side frames 111, thus the battery 200 lifted by the lifting frame 21 can also be located between the two side frames 111. In this way, during the transfer of the battery 200, the two side frames 111 of the supporting frame 11 can protect the battery 200, reducing the risk of collision to both sides of the battery 200 along its width direction.

[0083] By adopting the above technical solution, the load-bearing frame 11 includes two side frame portions 111 and a top frame portion 112. The side frame portions 111 can be equipped with casters 12 to facilitate the movement of the battery transfer device 100. Along the first direction X, the hoisting frame 21 is located between the two side frame portions 111. The two side frame portions 111 can protect the battery 200 and reduce the risk of the battery 200 being easily damaged by collisions on both sides.

[0084] In some embodiments, along the second direction Y, the two ends of the hoisting frame 21 extend beyond the main frame 10, and the second direction Y is perpendicular to the first direction X and the vertical direction.

[0085] The second direction Y can be the length direction of the battery 200. Along the second direction Y, both ends of the lifting frame 21 extend beyond the main frame 10. It can be understood that the dimension of the lifting frame 21 along the second direction Y is greater than the dimension of the main frame 10 along the second direction Y. Optionally, the length of the battery 200 is greater than the dimension of the lifting frame 21 along the second direction Y. Since the lifting fixture 20 connects the battery 200 by lifting, the lifting frame 21 can fix a battery 200 that is longer than its own length.

[0086] Optionally, the two ends of the hoisting frame 21 extend out of the main frame 10 by the same amount to ensure that the main frame 10 is subjected to balanced forces.

[0087] Optionally, along the second direction Y, the dimension by which each end of the lifting frame 21 extends beyond the main frame 10 is 10% to 70% of the dimension of the main frame 10; further, the dimension by which each end of the lifting frame 21 extends beyond the main frame 10 is 30% to 60% of the dimension of the main frame 10.

[0088] Optionally, the dimension of the main frame 10 along the second direction Y is less than or equal to one-third of the length of the battery 200, which can give the main frame 10 sufficient support stability and reduce the volume and weight of the main frame 10.

[0089] By adopting the above technical solution, the dimension of the main frame 10 along the second direction Y is smaller than the dimension of the hoisting frame 21, which helps to reduce the weight of the main frame 10 and facilitates the movement of the battery transfer device 100.

[0090] In some embodiments, please refer to Figure 4 and Figure 6 The side frame 111 includes a support 1111 and a caster mounting component 1112. The two ends of the support 1111 in the vertical direction are respectively connected to the top frame 112 and the caster mounting component 1112. Multiple casters 12 are connected to the caster mounting component 1112.

[0091] The support part 1111 extends vertically and connects between the top frame part 112 and the caster mounting part 1112. The support part 1111 can be a hollow frame, plate or other structure.

[0092] Caster mounting part 1112 extends along the second direction Y, such as Figure 1 As shown, in some embodiments, the caster mounting component 1112 includes two sub-mounting components arranged along the second direction Y. The sub-mounting component includes a horizontally arranged frame mounting portion and a caster mounting portion located at both ends of the frame mounting portion and extending in the vertical direction. Optionally, the caster mounting component 1112 is provided with three casters 12, wherein two casters 12 are respectively located on the caster 12 mounting portions at the front and rear ends of the caster mounting component 1112, and the middle caster 12 is located at the connection of the two sub-mounting components. The other caster 12 mounting portions of the two sub-mounting components are fitted together and are jointly mounted on the same caster 12.

[0093] It is understood that the structure of the caster mounting component 1112 can be flexibly adjusted, and the caster mounting component 1112 can also connect two or more casters 12.

[0094] By adopting the above technical solution, the caster mounting component 1112 can install more casters 12 and improve the stability of the main frame 10, and also improve the mobility of the battery transfer device 100.

[0095] like Figure 6 As shown, in some embodiments, in each side frame portion 111, the size L1 of the caster mount 1112 along the second direction Y is greater than the size L2 of the support portion 1111 along the second direction Y, and the two ends of the caster mount 1112 along the second direction Y extend beyond the support portion 1111.

[0096] The support portion 1111 is connected to the middle of the caster mount 1112. Both ends of the caster mount 1112 along the second direction are located on the outer sides of the support portion 1111. The caster mount 1112 and the caster 12 provide stable support for the support portion 1111. Optionally, L1 is 1.1 to 2 times L2, allowing the caster mount 1112 to provide good support without occupying excessive space. It is understood that the dimensions of the caster mount 1112 and the support portion 1111 can also be set according to requirements.

[0097] By adopting the above technical solution, the size of the caster mounting part 1112 along the second direction Y is larger than the size of the support part 1111, which improves the stability of the main frame 10 and reduces the risk of the main frame 10 tipping over.

[0098] In some embodiments, at least one of the side frame portion 111, the top frame portion 112, and the hoisting frame 21 is a hollow frame.

[0099] A hollow frame refers to a frame with a hollow design, forming an internal cavity. The frame structure is composed of materials with a certain strength and rigidity, which can withstand external forces and provide support. Structural reinforcements can be installed inside the cavity of the frame.

[0100] Optional, such as Figure 1 and Figure 4 As shown, the side frame 111, top frame 112, and lifting frame 21 are all hollow frames. The support portion 1111 of the side frame 111 includes two uprights and a crossbar connecting the two uprights. The top frame 112 includes two support rods and a first reinforcing rod 1121 located between the two support rods. The lifting frame 21 includes a square enclosure 211 and a second reinforcing rod 212 located within the enclosure 211.

[0101] By adopting the above technical solution, at least one of the side frame 111, top frame 112 and hoisting frame 21 is hollow, so as to reduce its weight, facilitate the movement of the battery transfer device 100, and improve the portability of the battery transfer device 100.

[0102] In some embodiments, the lifting frame 21 is detachably connected to the top frame portion 112.
