Fig. 1 to 7 illustrate an electricity swapping system in some embodiments, the electricity swapping system includes a battery storage, an electricity swapping support assembly 206, a first transfer device 205, a second transfer device 104, and a charging module 704.

Referring to fig. 1, 2 and 7, the battery storage includes a battery support 101, the battery support 101 includes a plurality of columns 201 and a plurality of beams 202, and the columns 201 and the beams 202 are staggered to form a plurality of storage positions for placing the batteries 102. The battery rack 101 has a transfer location and a charging location 702, wherein the transfer location may be one location or may include two separate locations, as shown in fig. 1 and fig. 2, and the transfer location may include a full-charge transfer location 203 and a insufficient-charge transfer location 103. The battery storage is further provided with a battery access for the first transfer device 205 to enter and exit, and in some embodiments, referring to fig. 1 and 2, a front opening of the full-charge transfer bay 203 in the battery rack 101 is the battery access. A charging module 704 is installed in the charging bay 702, and the charging module 704 is used to charge the battery in the charging bay 702.

The switch support assembly 206 is mounted in the low-voltage battery station 103, the switch support assembly 206 having a first state (shown in fig. 4) to clear the battery 102 and a second state (shown in fig. 5) to support the battery 102 at the low-voltage battery station 103. Referring to fig. 3, in some embodiments, the battery swap support assembly 206 includes a first support 301 and a second support 302, the first support 301 is fixed to a support structure of the transfer bay, where the support structure may be the cross bar 202 of the battery rack 101, the second support 302 is rotatably connected to the first support 301, the second support 302 is used for supporting the battery, and the second support 302 is capable of rotating relative to the first support 301. Specifically, the battery replacement support assembly 206 further includes a rotating shaft 303, the rotating shaft 303 is fixedly connected to the second support member 302, and the first support member 301 is sleeved on the outer periphery of the rotating shaft 303. In addition, the first support 301 and/or the second support 302 are provided with a stop structure for keeping the second support 302 in the second state. Referring to fig. 6, the abutting portion 601 of the first supporting member 301 and the abutting portion 601 of the second supporting member 302 are configured as a stopping structure, the abutting portion 601 of the first supporting member 301 and the abutting portion 601 of the second supporting member 302 can abut against each other, and the abutting between the abutting portions 601 can prevent the second supporting member 302 from rotating downward relative to the first supporting member 301, so that the second supporting member 302 can maintain the second state and support the battery 102, specifically, the bottom of the battery 102, when the first supporting member 301 is fixed to the battery holder 101 (can be fixed to the cross beam 202 of the battery holder 101 by a screw). Referring to fig. 4 and 5, during the process that the battery 102 rises upwards and enters the low-voltage transfer storage position 103, the side part of the battery 102 pushes the end part of the second support member 302 open, and the second support member 302 rotates upwards; when the battery 102 rises to a certain height, that is, the battery 102 passes over the second support 302 from bottom to top, the battery 102 no longer abuts against the end of the second support 302, the second support 302 rotates downwards due to gravity to reset, and then the battery 102 descends, and the second support 302 supports the battery 102.

The battery replacement support assembly 206 is not limited to the above arrangement manner, as long as the battery replacement support assembly has two states capable of avoiding the battery 102 and supporting the battery 102, for example, in other embodiments, the battery replacement support assembly 206 may be arranged to realize avoiding and supporting through a telescopic rod; or, a supporting piece which can horizontally rotate to different positions is arranged to realize avoiding and supporting; this is not intended to be an example of a possible arrangement.

Referring to fig. 4, the first transfer device 205 is capable of entering and exiting from a battery door of the battery storage, the first transfer device 205 includes a lift-up mechanism 401 and a carrier 402, the carrier 402 is used for placing the battery 102, and the lift-up mechanism 401 is capable of driving the carrier 402 to move up and down.

The process of replacing the battery by the battery replacement system is described below with reference to fig. 1 to 5.

First, the first transfer device 205 receives the low-power battery and then moves to a position below the low-power transfer bay 103.

Then, the jacking mechanism 401 acts to jack the bearing member 402 and the battery 102 on the bearing member 402, and the battery replacement support assembly 206 is in a first state (avoidance state); when the battery 102 rises to a certain height, the battery 102 crosses the battery replacement support assembly 206 from bottom to top, and the battery replacement support assembly 206 is switched to a second state (support state); subsequently, the carrier 402 is driven by the jacking mechanism 401 to descend, the battery 102 descends until being abutted by the second support 302 and does not descend any more, the battery 102 is stably placed in the low-power transfer position 103, and the carrier 402 continues to descend and reset under the driving of the jacking mechanism 401.

After the carrier 402 is lowered and reset, the second transfer device 104 transfers the insufficient-charge battery that has just been placed in the insufficient-charge transfer storage location 103 to the charge storage location 702, and transfers the fully-charged battery that has been charged in the charge storage location 702 to the fully-charge transfer storage location 203, specifically, the second transfer device 104 may directly place the battery on the carrier 402 of the first transfer device 205 located in the fully-charge transfer storage location 203, and then the first transfer device 205 may carry the fully-charged battery and leave the battery storage from the battery entrance. The insufficient battery transferred to the charging station 702 is charged in the charging station, and the insufficient battery after charging can be used as a full battery for the next battery replacement.

According to the power conversion system provided by the invention, the first transfer device 205 lifts the battery 102, and the power conversion support component 206 avoids and supports the battery 102, so that the insufficient battery is placed in the insufficient transfer storage position 103, the insufficient battery in the insufficient transfer storage position 103 is transferred to the charging storage position 702 through the second transfer device 104, and the full-charge battery is transferred to the full-charge transfer storage position 203 from the charging storage position 702. The battery replacement system provided by the invention is simple in structure and operation process, and is beneficial to improving the battery replacement efficiency.

It should be noted that, the above steps correspond to the arrangement mode that the transfer station includes the full-power transfer station 203 and the insufficient-power transfer station 103, and when the transfer station is specifically a single station (relative to the case where the full-power transfer station 203 and the insufficient-power transfer station 103 share a single station), the specific steps and the corresponding structural arrangement are slightly different. In the setting mode that the transfer storage location is specifically a storage location, the first transfer device 205 first places the insufficient-power battery into the transfer storage location, then the second transfer device 104 transfers the insufficient-power battery to the charging storage location 702, and transfers the full-power battery into the transfer storage location, and then the first transfer device 205 takes the full-power battery in the transfer storage location away from the battery storage. Referring to fig. 3, in order to facilitate the first transfer device 205 to take the fully charged battery in the transfer bay from the battery storage bay, in an arrangement mode in which the transfer bay is specifically one bay, the power conversion support assemblies 206 installed in the transfer bay are disposed on both sides of a path in which the fully charged battery leaves the transfer bay, and no cross beam 202 is disposed on the path in which the fully charged battery leaves the transfer bay. Referring to fig. 3, if the fully charged battery needs to move forward and leave the middle transfer position, the cross beam 202 should not be disposed at the front side of the middle transfer position, and the switching support assembly 206 may be fixed to support structures such as the cross beam 202 at the left and right sides of the middle transfer position.

In addition, fig. 1 and fig. 2 show an arrangement manner in which the shortage transfer station 103 is located above the full transfer station 203, and in fact, the full transfer station 203 and the shortage transfer station 103 are not limited to this arrangement manner, for example, the full transfer station 203 and the shortage transfer station 103 may be located at the same height and adjacently arranged, or the full transfer station 203 and the shortage transfer station 103 may be separated by a larger distance, and this is not necessarily a feasible arrangement manner. Referring to fig. 1 and 2, in such an arrangement that the insufficient-power transfer storage location 103 is located above the full-power transfer storage location 203, after the first transfer device 205 transfers the insufficient-power battery into the insufficient-power transfer storage location 103, the insufficient-power battery does not need to be moved to a corresponding position of the full-power transfer storage location 203 along the length direction (or other directions) of the battery storage to carry the full-power battery, which is beneficial to reducing the structural complexity of the power conversion system (for example, a rail extending along the length direction of the battery storage does not need to be provided, and a steering mechanism does not need to be provided on the first transfer device), and the construction cost of the power conversion system is reduced.

Referring to fig. 3, in some embodiments, the battery replacement support assembly 206 further includes a first elastic member 304, two ends of the first elastic member 304 are respectively connected to the first support 301 and the second support 302, and the first elastic member 304 can drive the second support 302 to reset. The first elastic member 304 may be configured as a torsion spring, and the structure and force characteristics of the torsion spring are more suitable for restoring the first supporting member 301 and the second supporting member 302 rotating relatively. Referring to fig. 3, the first elastic member 304 is also sleeved on the rotating shaft 303, and one end of the first elastic member 304 is clamped with the first supporting member 301, and the other end is clamped with the second supporting member 302. When the second supporting member 302 rotates upward relative to the first supporting member 301 by an external force, the first elastic member 304 is stretched circumferentially; when the external force disappears, the first elastic element 304 needs to be restored, the elastic force of the first elastic element 304 drives the second supporting element 302 to be restored, and the battery replacement supporting assembly 206 is restored to the state shown in fig. 3.

In some embodiments, referring to fig. 2, in some embodiments, the full charge transfer storage location 203 may be disposed at the bottom of the battery storage, and the battery entrance is disposed at the full charge transfer storage location 203, in this manner, the first transfer device 205 is directly located in the full charge transfer storage location 203 after entering the battery storage, and the first transfer device 205 may directly support the full charge battery (after the first transfer device 205 enters the full charge transfer storage location 203 and completes the operation of entering the insufficient charge transfer storage location 103, the full charge battery enters the full charge transfer storage location 203), without disposing a structure for supporting the battery at the bottom of the full charge transfer storage location 203.

Fig. 12 and 13 show a specific structure of the first transfer device 205 in some embodiments. The jacking mechanism 401 is mounted on the mounting base 1201, and the jacking mechanism 401 may be specifically configured as a lead screw slider mechanism, the lead screw being driven by a motor, the slider portion being fixedly connected to the carrier 402 (not shown in detail). The first transfer device 205 further includes a first displacement mechanism 1202 and a second displacement mechanism 1203, the first displacement mechanism 1202 is also mounted on the mounting base 1201, the first displacement mechanism 1202 may be configured as a combination of a motor and a roller (the roller is not shown), the roller is matched with a track, and the motor drives the roller to rotate, so that the mounting base 1201 moves left and right along the track (here, the left and right are based on the direction of fig. 12, if the first transfer device 205 is applied to the structure shown in fig. 1, the extending direction of the track should correspond to the front and back direction of fig. 1). A second displacement mechanism 1203 is installed on the mounting base 1201, the second displacement mechanism 1203 is used for driving the carrier 402 to move in the front-back direction, and the second displacement mechanism 1203 may also be specifically configured as a lead screw slider mechanism.

Referring to fig. 13, the first transfer device 205 further includes a rotating base 1303, the rotating base 1303 is connected to the carrier 402, the rotating base 1303 is slidably mounted on the mounting base 1201 (corresponding slide rails extend in the front-back direction, not shown in detail), and the angle adjustment driving mechanism 1304 can drive the rotating base 1303 to rotate so as to adjust the angles of the carrier 402 and the batteries on the carrier 402 relative to the mounting base. The periphery of the rotating seat 1303 may be provided with teeth, and the angle adjustment driving mechanism 1304 may include a motor, a transmission belt, and a gear, the motor is connected to the gear through the transmission belt, the gear is engaged with the rotating seat 1303, and the motor drives the gear to rotate so as to rotate the rotating seat 1303.

The first displacement mechanism 1202 mainly moves the first transfer device 205 as a whole, and causes the first transfer device 205 to be transferred between the battery storage and the vehicle; the second displacement mechanism 1203 is mainly used for fine-tuning the position of the carrier 402, so that the battery supported by the carrier 402 is aligned with a corresponding storage location or an installation location on the automobile; the angle adjustment mechanism 1304 is mainly used to rotate the battery and adjust the angle of the battery.

Referring to fig. 13, the first transfer apparatus 205 further includes an unlocking member 1302 and an unlocking driving mechanism 1301, wherein the unlocking member 1302 is used for unlocking the battery from the vehicle, and the unlocking driving mechanism 1301 is used for driving the unlocking member 1302 to move up and down relative to the carrier 402. Specifically, a buckle 403 is arranged at the edge of the battery, and a through hole is formed in the buckle 403, and the through hole can be used for inserting a buckle slider on a vehicle chassis (the buckle slider extends towards the center direction of the battery and is inserted into the buckle 403); the top end of the unlocking piece 1302 is provided with an inclined plane, the inclined plane is back to the center of the battery, during unlocking, the unlocking driving mechanism 1301 drives the unlocking piece 1302 to ascend, the unlocking piece 1302 is inserted between the buckle 403 and the main body 404 of the battery 102 from bottom to top, the unlocking piece 1302 pushes the buckle sliding block on the automobile chassis, the buckle sliding block moves towards the direction far away from the center of the main body 404 until the buckle sliding block is separated from the buckle 403, and therefore unlocking is achieved. The basic principle of the recovery locking is similar to that, after the battery rises to the preset position, the buckle slider on the automobile is opposite to the through hole on the buckle 403, the buckle slider has the tendency of inserting into the buckle 403 but is supported and blocked by the unlocking piece 1302, then the unlocking piece 1302 gradually descends relative to the bearing piece 402, and the buckle slider gradually inserts into the buckle 403, so that the battery is fixed. In this arrangement, the first transfer device 205 is used not only as a device for transferring the battery, but also as a device for attaching and detaching the battery during the battery replacement process, which is advantageous for further simplifying or saving the device or mechanism required for replacing the battery.

Referring to fig. 14, in some embodiments, second transfer device 104 may be provided as a relatively low cost stacker. The second transfer device 104 comprises a base frame 1401, a fork 1405, a first driving mechanism 1402, a second driving mechanism 1403 and a third driving mechanism 1404, wherein the fork 1405 is plate-shaped, and the fork 1405 can support a battery; the first drive mechanism 1402, the second drive mechanism 1403, and the third drive mechanism 1404 are all connected to the base frame. The first driving mechanism 1402 is used to drive the forks to move along the length direction of the battery storage warehouse, and referring to fig. 1, the first driving mechanism 1402 drives the whole second transfer device 104 to move along the left-right direction, and the first driving mechanism 1402 may specifically include a motor and a roller, and the motor can drive the roller to rotate, so that the second transfer device moves integrally. The second driving mechanism 1403 specifically comprises a motor, a gear and a chain, the motor is connected with the gear, the gear is meshed with the chain, the chain is connected with the lifting platform 1406 provided with the fork 1405, and the motor drives the chain to move to drive the lifting platform 1406 to lift. The third drive mechanism 1404 may include intermeshing gears and racks, with the gears rotating to move the forks back and forth. When the fork 1405 moves backward, the fork 1405 extends into the battery storage, and when the fork 1405 moves forward, the fork 1405 is drawn out from the battery storage. In other embodiments, the second transfer device 104 may also be configured as a multi-axis robot with high motion precision. The second transfer device 104 may transfer the battery between the transfer location and the charging location 702, or may transfer the battery between different charging locations 702.

Referring to fig. 2, in some embodiments, a low-charge transfer bay 103 for storing low-charge batteries is disposed above a full-charge transfer bay 203 for storing full-charge batteries. Under this kind of setting mode, after moving insufficient voltage battery into insufficient voltage transfer storehouse position 103, before moving out the full charge battery in full voltage transfer storehouse position 203, first transfer device 205 can need not remove, is favorable to reducing the interval time between moving in the insufficient voltage battery and moving out the full charge battery, improves the efficiency of changing the battery. It should be noted that, in this arrangement, when the battery 102 is moved into the low-power transfer position 103, the jacking mechanism 401 needs to drive the battery 102 to pass over the full-power transfer position 203; when the insufficient-capacity battery is moved into the insufficient-capacity transfer storage location 103, the insufficient-capacity battery does not exist in the full-capacity transfer storage location 203, and the increase of the insufficient-capacity battery is not hindered (after the insufficient-capacity battery is moved into the insufficient-capacity transfer storage location 103, the full-capacity battery is moved into the full-capacity transfer storage location 203 by the second transfer device 104).

In some embodiments, the battery replacement system further includes a service module, the service module is adjacent to the battery support 101, the service module is electrically connected to the battery 102 on the battery support 101, and the service module is used for detecting and maintaining the battery 102.
