Moreover, the overall structure of the above flipping device is simple, with high manufacturability, which can reduce the manufacturing cost to a certain extent, and is convenient for operation and use.

[0007] According to some embodiments of the present application, the flipping assembly includes a first connecting member, and the first connecting member is used to connect the battery and drive the battery to flip.

[0008] In these alternative embodiments, such a setting simplifies the structure of the flipping device, improves the quickness and convenience of installation and use, and saves costs.

[0009] According to some embodiments of the present application, the flipping assembly further includes a second connecting member, the second connecting member is used to connect the first end of the battery, and the first connecting member is used to connect the second end of the battery, and the first end and the second end are oppositely arranged.

[0010] In these alternative embodiments, the flipping assembly includes a first connecting member and a second connecting member. The two connecting members work together to improve the connection stability of the flipping assembly to the battery, and can also effectively reduce the risk of the battery detaching from the flipping assembly during flipping. In addition, the arrangement of the first connecting member and the second connecting member enables the flipping assembly to be further miniaturized and simplified, facilitating mechanical manufacturing.

[0011] According to some embodiments of the present application, the rotating shaft includes a first rotating shaft and a second rotating shaft. The first rotating shaft connects the driving member and the first connecting member, and the second rotating shaft connects the driving member and the second connecting member.

[0012] In these alternative embodiments, the first connecting member and the second rotating shaft are respectively provided with corresponding rotating shafts. The driving member can drive the first rotating shaft and the second rotating shaft to rotate individually or alternately, making the flipping assembly more flexible and enabling more efficient adjustment of the flipping angle of the battery.

[0013] According to some embodiments of the present application, the first connecting member includes a connecting portion extending in a first direction. The connecting portion abuts against the end face of the battery, and the first direction is perpendicular to the thickness direction of the battery.

[0014] In these alternative embodiments, with such an arrangement, the battery can be clamped at both ends of the battery to drive the battery to flip. Moreover, the connecting portions of the first connecting member and the second battery can adjust the relative distance in the first direction between the two connecting portions according to the size of the battery in the first direction, so as to clamp batteries of different sizes, eliminating the need to design different flipping assemblies for batteries of different sizes and improving the applicability of the flipping assembly.

[0015] According to some embodiments of the present application, the width of the connecting portion gradually increases in the direction of the rotating shaft towards the battery.

[0016] In these alternative embodiments, the connecting portion connects the battery and the rotating shaft, and the width of the connecting portion gradually increases in the direction of the rotating shaft towards the battery. The end of the connecting portion with a smaller width is connected to the rotating shaft, improving the fit between the connecting portion and the rotating shaft.

Moreover, the large-area abutment of the connecting portion with the battery can also improve the clamping stability of the battery.

[0017] According to some embodiments of the present application, an avoidance groove is formed on the side of the connecting portion close to the battery. The avoidance groove is used to avoid the pole post of the battery.

[0018] In these alternative embodiments, with such an arrangement, the connecting portion can avoid the pole post on the battery, further improving the fit between the flipping assembly and the battery.

[0019] According to some embodiments of the present application, the first connecting member includes a first connecting portion, a second connecting portion, and a fixing portion.

By clamping the opposite surfaces of the battery with the first connecting member and the second connecting member, stable clamping of the battery can be achieved, and the clamping position can be adjusted accordingly according to the structure of the battery, effectively avoiding non-connected parts of the battery. Moreover, by clamping the two surfaces of the battery, the connection stability between the flipping assembly and the battery is further improved.

[0021] According to some embodiments of the present application, the first connecting portion is slidably connected to the fixing portion so that the first connecting portion moves relative to the fixing portion along the second direction.

[0022] In these alternative embodiments, the first connecting portion is slidably connected to the fixing portion and moves along the second direction, thereby adjusting the relative distance between the first connecting portion and the second connecting portion along the second direction, and further adjusting the gap between the first connecting portion and the second connecting portion, so that batteries of different thicknesses can be clamped, improving the versatility of the flipping assembly.

[0023] According to some embodiments of the present application, the second connecting portion is slidably connected to the fixing portion so that the first connecting portion moves relative to the fixing portion along the second direction.

[0024] In these alternative embodiments, with such a setting, both the first connecting portion and the second connecting portion can move in the second direction, making the flipping assembly more flexible and improving the operation efficiency.

[0025] According to some embodiments of the present application, the flipping device further includes a limiting assembly disposed at one end of the flipping assembly facing the battery, and is used to cooperate with the battery to limit the separation of the battery from the flipping assembly.

At the same time, the arrangement of the limiting protrusion and the limiting groove can also increase the connection area between the battery and the flipping assembly, enhance the contact stability, improve the connection strength, and reduce the pressure on the limiting protrusion, thus avoiding the cracking or deformation of the limiting protrusion under the action of the battery and the flipping assembly.

[0036] In the battery swapping method provided by the present application, the battery to be charged is rotated 180° before charging, then installed in the charging bin for charging, and then the charging bin is charged. Therefore, each fully charged battery taken from the charging bin is a flipped battery, so that the electrolyte in the battery fully wets the electrode assembly, reduces the lithium plating phenomenon, improves the safety of the battery, and further reduces the potential safety hazard of the battery swapping system.

[0084] Currently, with the continuous development of battery technology, the application scenarios of batteries are also increasing continuously. How to quickly replenish the electrical energy of the battery has become one of the factors restricting the popularization of batteries. According to the principle of energy storage of the battery itself, the battery needs to replenish electrical energy periodically, and the time for the battery to replenish electrical energy through charging is relatively long. Therefore, by directly replacing the battery of the electrical device and using a fully charged battery to replace the depleted battery, the efficiency of replenishing electrical energy for the electrical device can be effectively improved. As a result, the battery swapping system has emerged and is becoming more and more popular in life. The battery swapping system is an energy station that provides charging for the power battery of an electric vehicle and quickly replaces the power battery. With the large-scale layout of the battery swapping system, ensuring the safety of the battery swapping system has also attracted more and more widespread attention.

[0085] Based on the structural design of the battery, during the long-term use of the battery in the electrical device, due to the gravitational force, the electrolyte at the upper end of the battery is insufficient, resulting in poor wetting of the upper end of the electrode assembly in the battery, thereby causing electrolyte bridge breakage and serious lithium plating phenomenon. Lithium plating not only reduces the battery performance and significantly shortens the cycle life, but also limits the fast charging capacity of the battery. In addition, when lithium plating occurs in a battery cell, the deposited lithium metal is very reactive and can react with the electrolyte at a relatively low temperature, resulting in a decrease in the self-heating starting temperature of the battery and an increase in the self-heating rate, seriously endangering the safety of the battery and triggering potential safety hazards in the battery swapping system.

[0086] In view of the above problems, through in-depth research, the inventor has proposed a flipping device. The flipping device can flip the battery, thereby improving the wetting degree of the electrolyte in the battery, reducing to a certain extent the poor wetting of part of the electrode assembly in the battery, thereby causing electrolyte bridge breakage and serious lithium plating phenomenon, improving the safety of the battery, and further reducing the potential safety hazards in the battery swapping system.

[0087] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery may include a battery module or a battery pack, etc. The battery can be applied to vehicles, mobile phones, portable devices, laptops, ships, spacecrafts, electric toys, electric tools, energy storage systems, and so on.

[0088] The battery swapping system disclosed in the embodiments of the present application is used to place batteries and charge the batteries, and replace the fully charged battery with an electric device. The electric device can be a vehicle. 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 electric vehicle, or an extended-range electric vehicle, etc. Exemplarily, the electric device can be a heavy truck.

[0089] For the convenience of description in the following embodiments, the electric device in an embodiment of the present application is taken as an example of a vehicle for illustration.

[0090] As shown in FIG. 1, Figure 1 is a schematic structural diagram of a battery swapping system provided by some embodiments of the present application.

[0091] As Figure 1 shown, the battery swapping system of the embodiment of the present application includes a charging bin 100 and a battery swapping platform 200. The battery swapping platform is used to support the electric device, and the charging bin 100 is used to store batteries and charge the batteries to replace the fully charged battery onto the electric device, where the electric device is a vehicle 300.

[0092] Referring to Figure 2 and Figure 3 , Figure 2 is a schematic structural diagram of a flipping device according to some embodiments of the present application; Figure 3 is a schematic structural diagram of a flipping device according to other embodiments of the present application.

[0093] As Figures 1 to 3 shown, a flipping device 10 of a battery swapping system of the present application includes a flipping assembly 1, a rotating shaft 2, and a driving member 3. The flipping assembly 1 is used to connect the battery. The rotating shaft 2 is connected to the flipping assembly 1. The driving member 3 is connected to the rotating shaft 2, and the driving member 3 drives the flipping assembly 1 to rotate through the rotating shaft 2.

[0094] The flipping assembly 1 is used to connect the battery. There are various connection methods between the flipping assembly 1 and the battery, such as clamping connection, plug-in connection, clamping connection, bonding, or threaded connection, etc., to ensure the stability between the flipping assembly 1 and the battery, and the flipping assembly 1 can also drive the battery to flip. The axis of rotation of the battery is perpendicular to the thickness direction of the battery to be charged. The manufacturing material of the flipping assembly 1 can also be various, such as steel, aluminum alloy, or other composite materials, etc. Optionally, one material is carbon fiber composite material, which has the advantages of light weight, high strength, and strong impact resistance.

[0095] The flipping component 1 of the present application can drive the battery to flip, and the angle by which the flipping component 1 can drive the battery to flip is 0 to 360°.

[0096] Exemplarily, the battery has a first surface and a second surface that are symmetric with each other in the thickness direction. The flipping component 1 is connected to the battery. At this time, the first surface of the battery faces upward. By driving the battery to flip through the flipping component 1, the axis of rotation of the battery is perpendicular to the thickness direction of the battery to be charged, so that the second surface of the battery faces upward. At this time, the flipping angle of the battery is 180°.

[0097] The driving member 3 is connected to the rotating shaft 2. The driving member 3 provides a driving force to drive the rotating shaft 2 to rotate, so that the rotating shaft 2 rotates around its own axis direction and drives the flipping component 1 to rotate, thereby realizing the flipping of the battery.

[0098] Optionally, the driving member 3 is selected from a driving motor, a cylinder or an electric cylinder.

[0099] The flipping device 10 of the battery swapping system provided by the present application can flip the battery, thereby improving the wetting degree of the electrolyte in the battery, reducing the poor wetting of the electrode assembly part in the battery to a certain extent, thereby causing the electrolyte to break the bridge and causing serious lithium plating phenomenon, improving the safety of the battery, and further reducing the safety hazards of the battery swapping system. Moreover, the overall structure of the above-mentioned flipping device 10 is simple, the manufacturability is high, the manufacturing cost can be reduced to a certain extent, and it is convenient to operate and use.

[0100] According to some embodiments of the present application, as Figure 2 and Figure 3 shown, the flipping component 1 includes a first connecting member 11, and the first connecting member 11 is used to connect the battery and drive the battery to flip.

[0101] In some embodiments of the present application, the first connecting member 11 connects the battery and the rotating shaft 2, and drives the battery to flip through the driving member 3. Among them, the first connecting member 11 can be used alone to realize the flipping of the battery, and the first connecting member 11 can be used in cooperation with other components to realize the flipping of the battery. During the flipping process of the battery, the first connecting member 11 can stably connect with the battery.

[0102] Exemplarily, the first connecting member 11 includes a frame and a connecting block. The frame is provided with a receiving groove, and the battery can be embedded in the receiving groove and locked with the frame. The connecting block is connected to the rotating shaft 2. By driving the rotating shaft 2 to rotate through the driving member 3, the rotating shaft 2 drives the first connecting member 11 and the battery to flip synchronously.

[0103] Exemplarily, the first connecting member 11 includes a first clamping surface, a connecting frame, and a second clamping surface. The connecting frame connects the first clamping surface and the second clamping surface, and the connecting frame is connected to the rotating shaft 2. The first clamping surface is connected to the first surface of the battery, and the second clamping surface is connected to the second surface of the battery. The first surface and the second surface of the battery are oppositely arranged. By driving the rotating shaft 2 to rotate through the driving member 3, the rotating shaft 2 drives the first connecting member 11 and the battery to flip synchronously.

[0104] In these alternative embodiments, it is arranged in this way, simplifying the structure of the flipping device 10, improving the quickness and convenience of installation and use, and saving costs.

[0105] According to some embodiments of the present application, such as Figure 2 and Figure 3 As shown, the flipping assembly 1 further includes a second connecting member 12. The second connecting member 12 is used to connect the first end of the battery, and the second connecting member 12 is used to connect the second end of the battery. The first end and the second end are oppositely arranged.

[0106] In some embodiments of the present application, the battery includes a first end and a second end that are oppositely arranged. The first connecting member 11 connects the first end of the battery and the rotating shaft 2, and the second connecting member 12 connects the second end of the battery and the rotating shaft 2. The first connecting member 11 and the second connecting member 12 cooperate to clamp the battery.

[0107] Exemplarily, the battery structure is rectangular, having a length and a width. When the first end and the second end are at both ends in the length direction of the battery, the first connecting member 11 connects one end in the length direction of the battery, and the second connecting member 12 connects the other end in the length direction of the battery, clamping the battery at both ends in the length direction of the battery. The axis around which the first connecting member 11 and the second connecting member 12 drive the battery to rotate is parallel to the length direction of the battery; similarly, when the first end and the second end are at both ends in the width direction of the battery, the first connecting member 11 connects one end in the width direction of the battery, and the second connecting member 12 connects the other end in the width direction of the battery, clamping the battery at both ends in the width direction of the battery. The axis around which the first connecting member 11 and the second connecting member 12 drive the battery to rotate is parallel to the width direction of the battery.

[0108] Optionally, the first connecting member 11 and the second connecting member 12 have the same structure.

[0109] Optionally, the first connecting member 11 and the second connecting member 12 are mirror-symmetrical in structure.

[0110] Optionally, the first connecting member 11 and the second connecting member 12 can be connected to the same rotating shaft 2. By driving a rotating shaft 2 with a driving member 3, the first connecting member 11 and the second connecting member 12 can jointly drive the battery to flip; alternatively, the first connecting member 11 and the second connecting member 12 are each connected to a rotating shaft 2, and the two rotating shafts 2 are driven by a driving member 3 to enable the first connecting member 11 and the second connecting member 12 to jointly drive the battery to flip.

[0111] In these alternative embodiments, the flipping assembly 1 includes a first connecting member 11 and a second connecting member 12. The two connecting members act together to improve the connection stability of the flipping assembly 1 to the battery, and can also effectively reduce the risk of the battery detaching from the flipping assembly 1 during flipping. In addition, the arrangement of the first connecting member 11 and the second connecting member 12 enables the flipping assembly 1 to be further miniaturized and simplified, facilitating mechanical manufacturing.

[0112] According to some embodiments of the present application, the rotating shaft 2 includes a first rotating shaft 21 and a second rotating shaft 22. The first rotating shaft 21 is connected to the driving member 3 and the first connecting member 11, and the second rotating shaft 22 is connected to the driving member 3 and the second connecting member 12.

[0113] In some embodiments of the present application, the rotating shaft 2 includes a first rotating shaft 21 and a second rotating shaft 22. The driving member 3 can independently drive the first rotating shaft 21 to rotate and drive the second rotating shaft 22 to rotate. For example, when the driving member 3 drives the first rotating shaft 21 to rotate and drives the first connecting member 11 to rotate, the second connecting member 12 and the second rotating shaft 22 also rotate accordingly; similarly, when the driving member 3 drives the second rotating shaft 22 to rotate and drives the second connecting member 12 to rotate, the first connecting member 11 and the first rotating shaft 21 also rotate accordingly.

[0114] In these alternative embodiments, the first connecting member 11 and the second rotating shaft 22 are respectively provided with corresponding rotating shafts. The driving member 3 can drive the first rotating shaft 21 and the second rotating shaft 22 to rotate independently or alternately, making the flipping assembly 1 more flexible and enabling more efficient adjustment of the flipping angle of the battery.

[0115] According to some embodiments of the present application, the first connecting member 11 includes a connecting portion 111 extending along a first direction x. The connecting portion 111 abuts against the end face of the battery, and the first direction x is perpendicular to the thickness direction of the battery.

[0116] In some embodiments of the present application, the first connector 11 includes a connecting portion 111 extending along the first direction x, and the connecting portion 111 of the first connector 11 abuts against one end surface of the battery. Accordingly, the second connector 12 includes a connecting portion 111 extending along the first direction x, and the connecting portion 111 of the second connector 12 abuts against the other end surface of the battery, so that the connecting portion 111 of the first connector 11 and the connecting portion 111 of the second connector 12 abut against the two end surfaces of the battery in the first direction x to achieve stable clamping of the battery.

[0117] For example, when the battery structure is a rectangular body that is symmetrical in the vertical direction, it has a length and a width. When the first end face and the second end face of the battery are at both ends of the length direction of the battery, the connecting portion 111 of the first connecting member 11 and the connecting portion of the second connecting member 12 both extend along the length direction, that is, the first direction x is parallel to the length direction, the first connecting member 11 abuts against the first end face, and the second connecting member 12 abuts against the second end face. The first connecting member 11 and the second connecting member 12 clamp the battery at both ends of the length direction of the battery, and the first connecting member 11 and the second connecting member 12 drive the battery to rotate. The axis is parallel to the length direction of the battery; when the first end face and the second end face of the battery are at the two ends in the width direction of the battery, the connecting portion 111 of the first connecting member 11 and the connecting portion of the second connecting member 12 both extend in the width direction, that is, the first direction x is parallel to the width direction, the first connecting member 11 abuts against the first end face, and the second connecting member 12 abuts against the second end face. The first connecting member 11 and the second connecting member 12 clamp the battery at both end faces in the width direction of the battery, and the axis of the battery driven to rotate by the first connecting member 11 and the second connecting member 12 is parallel to the width direction of the battery.

[0118] Optionally, the connecting portion 111 is selected from a connecting plate, a connecting block or a connecting strip, etc.

[0119] Optionally, the connecting portion 111 of the first connecting member 11 and the connecting portion of the second connecting member 12 have the same structure.

[0120] In these optional embodiments, such a configuration allows the battery to be clamped at both ends of the battery to drive the battery to flip, and the connecting portion 111 of the first connecting member 11 and the connecting portion of the second connecting member 12 can adjust the relative distance between the connecting portions 111 along the first direction x according to the size of the battery along the first direction x, thereby achieving clamping of batteries of different sizes, eliminating the need to design different flip assemblies 1 for batteries of different sizes, thereby improving the applicability of the flip assembly 1.

[0121] According to some embodiments of the present application, Figure 2 As shown, the width of the connecting portion 111 gradually increases along the rotation axis 2 toward the battery.

[0122] Optionally, the width of the connecting portion 111 near one end of the rotating shaft 2 is equal to the diameter of the rotating shaft 2.

[0123] Optionally, the width of the connecting portion 111 near the battery end is equal to the width of the battery.

[0124] In these alternative embodiments, the connecting portion 111 connects the battery and the rotating shaft 2, and the width of the connecting portion 111 gradually increases along the direction of the rotating shaft 2 towards the battery. The end of the connecting portion 111 with a smaller width is connected to the rotating shaft 2 to improve the fit between the connecting portion 111 and the rotating shaft 2. The end of the connecting portion 111 with a larger width is connected to the battery to improve the fit between the connecting portion 111 and the battery. Moreover, the large-area abutment of the connecting portion 111 with the battery can also improve the clamping stability of the battery.

[0125] According to some embodiments of the present application, as Figure 2 shown, an avoidance groove 112 is provided on the side of the connecting portion 111 near the battery, and the avoidance groove 112 is used to avoid the pole post of the battery.

[0126] In these alternative embodiments, with such a setting, the connecting portion 111 can avoid the pole post on the battery, further improving the fit between the flipping assembly 1 and the battery.

[0127] According to some embodiments of the present application, as Figure 3 shown, the first connecting member 11 includes a first connecting portion 113, a second connecting portion 114, and a fixing portion 115. The fixing portion 115 is connected to the rotating shaft 2. The first connecting portion 113 and the second connecting portion 114 are provided at both ends of the fixing portion 115, and the first connecting portion 113 and the second connecting portion 114 are oppositely arranged along the second direction y. The first connecting portion 113 extends towards the battery direction and abuts against the first surface of the battery, and the second connecting portion 114 extends towards the battery direction and abuts against the second surface of the battery. The first surface and the second surface are oppositely arranged, and the second direction y is parallel to the thickness direction of the battery.

[0128] In some embodiments of the present application, the first connecting member 11 includes a first connecting portion 113, a second connecting portion 114, and a fixing portion 115. The first connecting portion 113 and the second connecting portion 114 are provided at both ends of the fixing portion 115, and the fixing portion 115 is connected to the rotating shaft 2. Among them, the battery has a first surface and a second surface oppositely arranged along the thickness direction. The first connecting portion 113 abuts against the first surface of the battery, and the second connecting portion 114 abuts against the second surface of the battery, thereby clamping the two surfaces of the battery and driving the battery to flip.

[0129] According to some other embodiments of the present application, the second connecting member 12 also includes a first connecting portion 113, a second connecting portion 114, and a fixing portion 115. The fixing portion 115 is connected to the rotating shaft 2. The first connecting portion 113 and the second connecting portion 114 are disposed at both ends of the fixing portion 115, and the first connecting portion 113 and the second connecting portion 114 are oppositely disposed along the second direction y. The first connecting portion 113 extends toward the battery and abuts against the first surface of the battery. The second connecting portion 114 extends toward the battery and abuts against the second surface of the battery. The first surface and the second surface are oppositely disposed, and the second direction y is parallel to the thickness direction of the battery.

[0130] Optionally, the first connecting member 11 has the same structure as the first connecting member 11, or the first connecting member 11 and the first connecting member 11 are mirror-symmetric in structure.

[0131] In the embodiment of the present application, when the flipping assembly 1 only includes the first connecting member 11, it can be understood that the battery can be stably clamped and driven to flip only by the first connecting member 11. The projection of the first connecting portion 113 on the first surface of the battery along the first direction x may be greater than or equal to the area of the first surface, or may be less than the area of the first surface. And the projection of the second connecting portion 114 on the second surface of the battery along the first direction x may be greater than or equal to the area of the second surface, or may be less than the area of the second surface. When the flipping assembly 1 includes the first connecting member 11 and the second connecting member 12, the projection of the first connecting portion 113 on the first surface of the battery along the first direction x is less than the area of the first surface, and the projection of the second connecting portion 114 on the second surface of the battery along the first direction x is less than the area of the second surface.

[0132] Optionally, the projection of the first connecting portion 113 on the first surface of the battery along the first direction x is equal to the projection of the second connecting portion 114 on the second surface of the battery along the first direction x.

[0133] In these optional embodiments, the first connecting portion 113 abuts against the first surface of the battery, and the second connecting portion 114 abuts against the second surface of the battery. The opposite surfaces of the battery are clamped by the first connecting member 11 and the second connecting member 12, so as to realize stable clamping of the battery, and the clamping position can be adjusted accordingly according to the structure of the battery, and the non-connected parts of the battery can be effectively avoided. Moreover, by clamping the two surfaces of the battery, the connection stability between the flipping assembly 1 and the battery is further improved.

[0134] According to some embodiments of the present application, the first connecting portion 113 is slidably connected to the fixing portion 115, so that the first connecting portion 113 moves relative to the fixing portion 115 along the second direction y.

[0135] In some embodiments of the present application, the first connecting portion 113 is slidably connected to the fixing portion 115. The first connecting portion 113 can move relative to the fixing portion 115 along the second direction y, so as to adjust the relative distance between the first connecting portion 113 and the second connecting portion 114 in the first direction x, wherein the first direction x is parallel to the thickness direction of the battery.

[0136] Exemplarily, one of the first connecting portion 113 and the fixing portion 115 is provided with a sliding groove, and the other is provided with a sliding rail. Through the sliding fit of the sliding groove and the sliding rail, the movement of the first connecting portion 113 in the second direction y is adjusted. When both the first connecting portion 113 and the second connecting portion 114 are in contact with and stably clamp the battery, the relative movement between the first connecting portion 113 and the fixing portion 115 can be restricted by a locking member.

[0137] In these alternative embodiments, the first connecting portion 113 is slidably connected to the fixing portion 115 and moves along the second direction y, so as to adjust the relative distance between the first connecting portion 113 and the second connecting portion 114 along the second direction y, and further adjust the gap between the first connecting portion 113 and the second connecting portion 114, so as to clamp batteries of different thicknesses and improve the versatility of the flipping assembly 1.

[0138] According to some embodiments of the present application, the second connecting portion 114 is slidably connected to the fixing portion 115, so that the first connecting portion 113 moves relative to the fixing portion 115 along the second direction y.

[0139] In these alternative embodiments, arranged in this way, both the first connecting portion 113 and the second connecting portion 114 can move in the second direction y, the flipping assembly 1 has higher flexibility, and the operation efficiency is improved.

[0140] With reference to Figures 4 to 6 , Figure 4 is a schematic structural diagram of the limiting assembly of the flipping device according to some embodiments of the present application; Figure 5 is a schematic structural diagram of the limiting assembly of the flipping device according to other embodiments of the present application; Figure 6 is a schematic structural diagram of the limiting assembly of the flipping device according to still other embodiments of the present application.

[0141] According to some embodiments of the present application, as Figures 4 to 6 shown, the flipping device further includes a limiting assembly 4. The limiting assembly 4 is arranged at one end of the flipping assembly 1 facing the battery and is used to cooperate with the battery to limit the separation of the battery from the flipping assembly 1.

[0142] In some embodiments of the present application, the flipping assembly 1 and the battery are further connected and fixed through the limiting assembly 4. The limiting assembly 4 can limit the flipping assembly 1 and the battery in a manner of adhesion, snap connection, plug connection or threaded connection.

[0143] In these alternative embodiments, the provision of the limiting member strengthens the connection strength between the battery and the flipping assembly 1 and effectively prevents the battery from slipping off the flipping assembly 1, thereby further ensuring the safety of the battery.

[0144] According to some embodiments of the present application, the limiting assembly 4 includes a limiting protrusion and a limiting groove that cooperate with each other. One of the limiting protrusion and the limiting groove is provided on the flipping assembly 1, and the other is provided on the battery.

[0145] In these alternative embodiments, the limiting protrusion and the limiting groove form a fitting structure, which can play a limiting role to restrict the battery from slipping off the flipping assembly 1. At the same time, the provision of the limiting protrusion and the limiting groove can also increase the connection area between the battery and the flipping assembly 1, increase the stability of contact, improve the connection strength, and reduce the pressure received by the limiting protrusion, avoiding the limiting protrusion from cracking or deforming under the action of the battery and the flipping assembly 1.

[0146] The second aspect of the present application also provides a battery swapping system, including a charging bin 100, a battery swapping platform 200, and a battery swapping device.

[0147] In the battery swapping system provided by the present application, the flipping device 10 is provided in the battery swapping device. During the movement of the battery between the battery swapping platform 200 and the charging bin 100, the flipping device 10 flips the battery so that the electrolyte in the battery fully wets the electrode assembly, reducing to a certain extent the defect of poor wetting of part of the electrode assembly in the battery, reducing the phenomenon of lithium plating, improving the safety of the battery, and further reducing the safety hazards of the battery swapping system. Moreover, the above-mentioned flipping device 10 is provided in the battery swapping device, and flipping can be achieved during the transportation of the battery, improving the integration of the battery swapping device.

Therefore, each fully charged battery taken from the charging bin 100 is a battery that has been flipped, so that the electrolyte in the battery fully wets the electrode assembly, reducing the phenomenon of lithium deposition, improving the safety of the battery, and further reducing the potential safety hazards of the battery swapping system. Moreover, there is no need to add additional working steps. The flipping is only carried out during the process of removing the battery from the electrical device 300 and transporting it to the charging bin 100 for charging, simplifying the operation steps, making it easy to operate and control, and improving work efficiency. In addition, rotating the battery to be charged before charging allows the electrolyte to fully wet the battery assembly before charging, further reducing the phenomenon of lithium deposition in the battery.

Therefore, each fully charged battery taken from the charging bin is flipped, so that the electrolyte in the battery fully wets the electrode assembly, reducing the phenomenon of lithium deposition, improving the safety of the battery, and further reducing the potential safety hazards of the battery swapping system. Moreover, there is no need to add additional working steps. Only during the process of removing the fully charged battery from the charging bin and rotating it to the electrical device, the operation steps are simplified, which is easy to operate and control, and improves work efficiency.

[0171] In these alternative embodiments, in the flipping device, the driving part drives the flipping component to rotate through the rotating shaft, so that the flipping component drives the fully charged battery to rotate 180° to realize the flipping of the fully charged battery. The battery of the present application is a battery with upper and lower symmetry. After rotating 180°, the fully charged battery can be directly installed onto the electrical device.

The width of the connecting portion 111 gradually increases along the direction of the rotating shaft 2 towards the battery. An avoidance groove 112 is provided on the side of the connecting portion 111 close to the battery. The second connecting member 12 includes a connecting portion extending in the first direction x.

Moreover, there is no need to add additional working steps.
