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 stop structures, 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 mutual 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 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 screws).

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 203 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 203 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 114 can enter and exit from the battery door of the battery storage, the first transfer device 114 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 can drive the carrier 402 to move up and down. The jacking mechanism 401 may be configured as an air cylinder, an oil cylinder, a scissor mechanism, or the like, and the carrier 402 may be configured as a pallet, but is not limited to the illustrated manner.

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

First, the first transfer device 114 receives the low-power battery and moves to a position below the low-power transfer bay 103.

Then the jacking mechanism 401 acts to jack up the bearing member 402 and the battery 102 on the bearing member 402, and the battery replacement support assembly 203 is in a first state (an avoidance state); when the battery 102 rises to a certain height, the battery 102 crosses the battery replacement support assembly 203 from bottom to top, and the battery replacement support assembly 203 is switched to a second state (support state); the carrier 402 is then driven by the jacking mechanism 401 to descend, the battery 102 descends until being abutted by the second support 302 and then does not descend, and the battery 102 is stably placed in the low-power transfer station 103. And the carrier 402 will continue to be lowered and reset under the drive of the jacking mechanism 401.

After the carrier 402 is lowered and reset, the second transfer apparatus 104 transfers the insufficient-power battery, which has just been placed in the insufficient-power transfer storage location 103, to the charging storage location 702; the first transfer device 114 moves to a position below the full charge transfer storage location 113, and then the lift mechanism 401 operates, and the carrier 402 lifts the full charge battery in the full charge transfer storage location 113 (the full charge battery may be placed in the full charge transfer storage location 113 in advance, for example, the full charge battery may enter the battery storage location at the first transfer device 114) and leaves the battery storage location together with the full charge battery.

According to the power conversion system provided by the invention, the first transfer device 205 is used for jacking the battery 102, and the power conversion support assembly 203 is used for avoiding and supporting the battery 102, so that the purpose that the insufficient battery is placed in the insufficient transfer storage position 103 is realized, 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 113 from the charging storage position 702; and the insufficient-power transfer storage location 103 and the full-power transfer storage location 113 do not overlap in the vertical direction, the process of placing the insufficient-power battery into the insufficient-power transfer storage location 103 by the first transfer device 205 does not interfere with the full-power battery in the full-power transfer storage location 113. The battery replacement system provided by the invention is simple in structure and operation process, and is beneficial to improving the battery replacement efficiency.

In some embodiments, the battery replacement support assembly 203 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 provided as a torsion spring, and the structure and force characteristics of the torsion spring are more suitable for restoring the second supporting member 302 capable of rotating movement. 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 203 is restored to the state shown in fig. 2.

After the carrier 402 is raised to a certain height, the battery 102 is separated from the support structure for supporting the battery in the full-charge transfer-storage location 113, the battery 102 is supported by the carrier 402, and then the first transfer device 114 and the battery 102 are moved away from the full-charge transfer-storage location 113 together. As shown in fig. 2, the first transfer device 114 moves leftward away from the full-electricity transfer bay 113. In this arrangement, the cross member 202 is not provided on the left side of the full-charge storage position 113, and the first transfer device 114 is not blocked when entering or exiting the full-charge storage position 113.

The battery replacement support assembly 203 supports the edge portion of the bottom of the battery 102, while the carrier 402 supports the central region of the bottom of the battery, and the lifting and lowering of the carrier 402 is not blocked by the battery replacement support assembly 203. The battery replacement support assembly 203 is directly used, so that other support structures for supporting the edge part of the battery are not needed to be additionally designed or used, and the design, production and manufacturing difficulty is reduced. Furthermore, in some embodiments, since the full charge transfer storage location 113 is provided with the transfer electric support assembly 203, the full charge battery can also enter the full charge transfer storage location 113 in a manner similar to the manner in which the insufficient charge battery enters the insufficient charge transfer storage location 103.

On the premise of not influencing the movement of each device in the system, the charging of the battery and the normal operation of the system, the charging storage position 702 can be arranged at any position of the battery bracket 101, and the battery 102 can be charged in the charging storage position 702. After the first transfer device 114 transfers the insufficient-power battery to the insufficient-power transfer storage location 103, the second transfer device 104 transfers the insufficient-power battery from the insufficient-power transfer storage location 103 to the charging storage location 702, and the insufficient-power battery is charged in the charging storage location 702; the fully charged battery in the charging bay 702 (which may be provided in plural) is transferred to the fully charged intermediate bay 113 by the second transfer device 104, and then the fully charged battery is sent out of the battery storage by the first transfer device 114. In some embodiments, the support beam 701 at the bottom of the charging store 702 is further provided with a positioning member 703, the positioning member 703 can abut against the side of the battery 102 to prevent the battery 102 from shifting and falling off the battery rack 101, and can also perform a primary positioning function when the second transfer device 104 places the battery 102 into the charging store 702.

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.

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 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 is made to move towards the direction far away from 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.

The following describes a process of electrically connecting the plug 804 with the battery 102. A part of the battery 102 abuts against the charging support 803 and drives the charging support 803 to move, and the driving member 802 connected to the charging support 803 rotates around the first connection portion 901; when the driving member 802 rotates, the plug 804 connected to the third connecting portion 903 also moves circularly around the first connecting portion 901. Referring to fig. 10 and 11, the plug 804 and the charging support 803 have the same moving direction, and since the second connecting portion 902 and the third connecting portion 903 are located on the same side of the first connecting portion 901, and the second connecting portion 902 is closer to the third connecting portion 903, the moving distance of the second connecting portion 902 is smaller than that of the third connecting portion 903, and the moving distance of the plug 804 is greater than that of the charging support 803. That is, the moving distance of the plug 804 is greater than the moving distance of the battery abutting against the charging support 803, and the plug 804 gradually approaches the battery 102 and is plugged into the battery 102. When the battery 102 is placed in the battery holder 101, the charging support 803 can be driven to move by the gravity of the battery 102 itself, so that the connection between the battery 102 and the plug 804 can be realized without applying an external force additionally to maintain the electrical connection therebetween. It should be noted that the battery 102 placed in the storage location is not supported by the charging support 803 alone, the support beam 701 is provided at the bottom of the storage location, and the contact surface between the charging support 803 and the battery 102 is slightly higher than the top surface of the support beam 701 in the initial state.
