[0002] At present, battery swap stations are widely used for battery swapping of new energy vehicles. A large number of battery packs are usually stored on the battery racks in the battery swap stations, and the battery racks can charge the battery packs while storing them. Batteries are usually taken out or put in from different heights of the battery racks by lifting and moving the battery transfer equipment.

[0003] The Chinese patent application with publication number CN211733721U discloses a battery transport device, which mainly includes a main frame and other structures, and the entire battery transport device can be raised and lowered in the height direction. The Chinese patent application with publication number CN106927385A discloses a battery loading and unloading replacement device, and the entire battery loading and unloading replacement device can be raised and lowered in the height direction.

[0004] In the above patent application, when transporting, inspecting, or installing batteries or battery racks, the battery transport equipment is usually removed or disassembled to leave maintenance space for maintenance personnel to enter and exit. However, disassembling or removing the equipment is very time-consuming and inconvenient for maintenance. Alternatively, the battery transport equipment can be moved to a location far away from the maintenance area. In this case, power is required to maintain the battery transport equipment in a fixed position. Therefore, once a power outage or failure occurs, the battery transport equipment will fall out of control, causing hidden dangers to the safety of maintenance personnel. Summary of the invention

[0026] The steering is achieved through the transition wheel, which facilitates the uniform installation of the movable gear levers on the column. They can all be installed at the same position without distinguishing between different installation positions. Finally, the steering of the transition wheel is used to achieve synchronous switching of the positions of all the movable gear levers, that is, they are extended into the travel channel or retracted at the same time.

[0027] Preferably, the synchronous belt is configured to pull back and forth in a first pulling direction and a second pulling direction opposite to the first pulling direction, wherein the synchronous belt pulls in the first pulling direction and drives each of the movable gear levers to rotate to an extended position, and the synchronous belt pulls in the second pulling direction and drives each of the movable gear levers to rotate to a retracted position.

The installation process saves manpower and material resources and improves the operating efficiency of the entire system.

[0040] Furthermore, when the battery transport equipment is guided by the columns, since the height of the columns is directly related to the height of the battery positions of the battery rack, the problem of inaccurate height positioning caused by the inconsistency between the height reference of the battery transport equipment and the height reference of the battery position is avoided.

[0054] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0055] like Figure 1-Figure 7 As shown, the present invention discloses a battery transfer system for a battery swap station or an energy storage station. Figure 1-Figure 3 As shown, the battery transfer system of this embodiment includes a battery rack 1 having a plurality of battery positions 12, a battery transfer device 2 for transferring batteries between the plurality of battery positions 12, and a vertical limiter. The battery transfer device 2 is used to transfer batteries between the plurality of battery positions 12 of the battery rack 1, the battery rack 1 has a plurality of columns 11 arranged in the vertical direction, and the vertical limiter is arranged on the battery rack 1.

[0056] In a preferred embodiment, the battery rack 1 has a guide mechanism in the vertical direction, and the guide mechanism includes four guide posts or two guide posts arranged one by one corresponding to the four ends or the middle positions of the two sides of the battery transport device 2. In this embodiment, the guide post is the column 11 of the battery rack 1, and the vertical limit device is arranged on the column 11. The vertical limit device makes full use of the structure of the original guide post and can be closer to the travel channel 10 to ensure the stability of the vertical limit.

[0057] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a plurality of battery positions 12 are arranged in the form of two rows of battery racks 1 at a preset interval, and the battery transfer equipment 2 is located between the two rows of battery racks 1. The battery pick-up and placement mechanism of the battery transfer equipment 2 is configured to be telescopically movable toward the battery positions 12 on both sides to pick up and place the battery packs. The four guide columns reuse the four columns 11 of the two rows of battery racks 1 close to the battery transfer equipment 2. Of course, in other embodiments, the battery positions 12 can also be arranged in the form of any number of rows of battery racks 1. The battery transfer equipment 2 can be a mobile device and is not limited to being arranged between the battery positions. The guide column can be other structures with a guiding function, and can be independently arranged from the column 11.

[0058] In a preferred embodiment, the reused column 11 has a guide surface that cooperates with the battery transport device. In a specific implementation, the rack in the transmission mechanism of the battery transport device can be fixed on the transmission surface, so as to cooperate with the gear of the transmission mechanism for transmission. The column 11 can also have a guide surface that cooperates with the battery transport device, so as to guide the lifting and lowering movement of the battery transport device. In this way, the installation of the transmission mechanism and the guidance of the battery transport device can be realized, the overall structure is simplified, the connection between the two is more compact, and the guiding strength can be improved, the cost can be reduced, the installation process saves manpower and material resources, and the operating efficiency of the entire system is improved.

[0059] The four guide columns reuse the columns 11 of the battery rack, and the battery transfer system can operate directly between two opposite battery racks 1 without installing additional guide columns, which simplifies the overall structure, makes the connection between the two more compact, and can improve the guiding strength, reduce costs, save manpower and material resources during the installation process, and improve the operating efficiency of the entire system. In addition, during the process of the battery transfer equipment being guided by the columns 11, since the height of the columns is directly related to the height of the battery compartment 12 of the battery rack 1, the problem of inaccurate height positioning caused by the inconsistency between the height reference of the battery transfer equipment and the height reference of the battery compartment is avoided.

[0060] like Figure 4-Figure 7As shown, this embodiment also discloses a vertical limit device for a battery transport device 2. The vertical limit device includes a plurality of movable levers 3 rotatably arranged on the battery rack 1. Figure 5 As shown, the movable lever 3 of this embodiment includes a shaft rod 31 rotatably fixed to the column 11 and a boss 32 fixed on the shaft rod 31 .

[0061] like Figure 2 As shown, in a preferred embodiment, the surface of the boss 32 forms a support surface for supporting the battery transport device 2. When the movable lever 3 rotates to the extended state extending into the travel channel 10 of the battery transport device 2, the boss 32 is driven to rotate to extend into the travel channel 10 by rotating the shaft 31. At this time, the boss 32 is supported under the battery transport device 2 to support and prevent it from falling. In this embodiment, the boss 32 set on the shaft 31 is driven to rotate into the travel channel of the battery transport device by rotating, thereby carrying and positioning the battery transport device 2 to prevent the battery transport device 2 from falling. The structure is simple and easy to operate.

[0062] In a preferred embodiment, the boss 32 is set to be used to limit the lower surface of the bottom frame of the battery transport device 2, and is received from bottom to top. However, in other embodiments, it can also be set on the upper surface of the bottom frame and one or more of the top frame. In other embodiments, the abutment position between the boss 32 and the battery transport device 2 for limiting can be set arbitrarily, as long as the limiting is achieved, which improves the flexibility of use and is applicable to the structure of various battery transport devices.

[0063] like Figure 2 In the preferred embodiment shown, the battery transport device 2 can be limited on the movable lever 3 and is in a limited position. Figure 6 When rotating in the direction of the arrow shown, the movable lever 3 completely rotates toward the inside of the battery rack 1 and leaves the travel channel 10. At this time, when the movable lever 3 rotates to the retracted state, the battery transfer device 2 contacts the limit and can be lifted and moved in the travel channel 10.

[0064] In this embodiment, the movable lever 3 is extended on the travel channel 10 of the battery transport device 2. When the battery transport device 2 is repaired, the movable lever 3 can be used to vertically position the battery transport device to prevent the battery transport device 2 from falling due to a fault caused by circuit or control problems, thereby avoiding potential safety hazards and improving safety. At the same time, the blocking of the movable lever 3 can ensure that the battery transport device will not fall, so the battery transport device no longer needs to be moved out of the travel channel. At the same time, after the maintenance is completed, only the movable lever 3 needs to be removed to resume operation, making the overall maintenance efficiency more efficient.

[0065] like Figure 6As shown, in a preferred embodiment, the movable lever 3 is rotatably arranged and switches between a limited state and an extended state by rotation. The rotatably arranged movable lever 3 facilitates state switching, and the battery transport equipment can be vertically limited by position switching when necessary. At the same time, the movable lever of this structure can reduce the occupied space when installed. The vertical limiting device of this embodiment also includes a linkage mechanism connected to the four movable levers 3, and the linkage mechanism controls the four movable levers 3 to be extended or retracted at the same time. The linkage mechanism is used to drive all the movable levers to act simultaneously at one time, realize position switching, improve operating efficiency, and improve convenience.

[0066] Of course, in other embodiments, the movable lever 3 can also be telescopically set, and can be extended or retracted by linear motion. The movable lever 3 can also be translated, and can be translated from the outside of the bottom of the battery transport device into the bottom of the battery transport device.

[0067] Specific as Figure 6 and Figure 7 As shown, in a preferred embodiment, the linkage mechanism includes a plurality of gears 5 fixedly connected to the plurality of shafts 31 and a synchronous belt 4 sleeved on the plurality of gears 5, and the synchronous belt 4 cooperates with the gears 5 to drive the shafts 31 to rotate. The linkage between all the movable levers is realized through the gears 5 and the synchronous belt 4, which has a simple structure, convenient operation, and reliable movement, and the movable levers 3 can be driven to rotate back and forth at the same time through the synchronous belt 4.

[0068] Therefore, if Figure 6 As shown, the synchronous belt 4 is configured to pull back and forth in a first pulling direction and a second pulling direction opposite to the first pulling direction. The first pulling direction is a clockwise direction, and the second pulling direction is a counterclockwise direction. The synchronous belt 4 pulls and drives each movable lever 3 to rotate to the extended position in the clockwise direction, and the synchronous belt 4 pulls and drives each movable lever 3 to rotate to the retracted position in the counterclockwise direction. Therefore, the synchronous belt only needs to switch back and forth between the first pulling direction and the second pulling direction to realize the position switching of the extended and retracted movable lever 3.

[0069] Of course, in other embodiments, the linkage mechanism may be other mechanisms that can link the movement of multiple components, such as a connecting rod mechanism or a traction rope mechanism that pulls together.

[0070] like Figure 6 As shown, in a preferred embodiment, the boss 32 is arranged at the same position on the same side of multiple columns 11, the number of columns 11 is four, and the four shafts 31 are arranged on the columns 11 one by one. The linkage mechanism also includes a transition wheel 6, which is meshed with the gear 5 on the adjacent shaft 31 corresponding to the operating handle 33. The transition wheel 6 is used to change the rotation direction of the corresponding shaft 31.

[0071] like Figure 6 As shown, in a preferred embodiment, the movable gear lever 3 is divided into a clockwise gear lever (such as Figure 6 The movable lever 3 in the upper left corner and the lower right corner) and the counterclockwise lever (such as Figure 6 The movable levers 3 are shown in the upper right corner and the lower left corner of the middle. These movable levers 3 extend into and out of the travel channel from different outer positions of the travel channel 10. The movable levers 3 extending from multiple directions can make the battery transport device 2 more balanced in force, ensure stability, and improve safety.

[0072] in, Figure 6 The movable lever 3 at the upper left corner and the lower right corner rotates from the extended position to the retracted position in the clockwise direction, and rotates from the retracted position to the extended position in the counterclockwise direction; Figure 6 The movable shift levers 3 at the upper right corner and the lower left corner rotate counterclockwise from the extended position to the retracted position, and rotate clockwise from the retracted position to the extended position.

[0073] Since the rotation directions of the movable levers 3 at different positions are different when extended, they are mainly divided into two directions, namely clockwise and counterclockwise. The transition wheel 6 is used to realize the steering, which is convenient for the uniform installation of the movable levers 3 on the column 11. They can all be installed at the same position without distinguishing the different installation positions. Finally, the transition wheel 6 is used to realize the synchronous switching of the positions of all the movable levers 3, that is, they are extended into the travel channel 10 at the same time or retracted at the same time. It is ensured that the levers can be extended at the same time regardless of clockwise or counterclockwise, ensuring the consistency of position switching.

[0074] like Figure 7 As shown, in a further preferred embodiment, the gear 5 connected to the transition wheel 6 further includes a first tooth portion 51 and a second tooth portion 52, wherein the first tooth portion 51 is meshed with the synchronous belt 4, and the second tooth portion 52 is meshed with the transition wheel 6. Thus, the motion can be transmitted to the movable lever 3 through the gear 5, and an indirect connection with the movable lever 3 is achieved through the transition wheel 6. Of course, in other embodiments, other arrangements can also be used to enable the gear to transmit the motion of the synchronous belt 4 to the transition wheel 6, for example, the same tooth portion of the gear 5 is connected to the transition wheel and the synchronous belt at the same time.

[0075] like Figure 5-Figure 7 As shown, in a preferred embodiment, the synchronous belt 4 has a closed extended shape and is arranged around the outer side of each gear 5. The closed synchronous belt 4 can maintain a stable connection with each driving end when moving back and forth, and is guaranteed not to fall out during the back and forth switching movement.

[0076] In this embodiment, at least one column 11 is provided with a movable lever 3, and each column 11 is provided with at least one movable lever 3. It is preferably configured that each column 11 is connected to a movable lever 3, wherein, Figure 7 As shown, the column 11 is connected to the shaft 31 of the movable lever 3 through the connecting seat 13. The connecting seat 13 is provided with a through hole, which allows the shaft 31 to rotate therein. The movable lever 3 is arranged on the column 11, making full use of the original structure of the battery rack 1, and each column 11 can be connected to one or more levers to meet different maintenance space requirements.

[0077] like Figure 7 As shown, in a preferred embodiment, one side 111 of the column 11 of this embodiment faces the battery transport device 2 and the travel channel 10. The other side 112 of the column 11 is not opposite to the battery transport device 2. In the case where the column is a square tube, the side 112 and the side 111 are arranged at an angle of 90 degrees, so that the boss 32 of the movable lever 3 can avoid the travel channel 10 after being retracted.

[0078] like Figure 5 As shown, in a preferred embodiment, the vertical limit device further includes a manual operating mechanism, which, as a part of the linkage mechanism, also includes an operating handle 33 connected to any one of the shaft rods 31, wherein the operating handle 33 is connected to the bottom of the shaft rod 31 in the vertical direction. The movable levers 3 are driven simultaneously by the linkage mechanism. The operating handle 33 drives at least two movable levers 3 to rotate synchronously. The operating handle 33 is convenient for the operator to hold the movable lever 3 to switch the position.

[0079] In other embodiments, the vertical limit device further includes a manual operating mechanism corresponding to the number of movable levers 3. In this case, the operating mechanism does not include a linkage mechanism, and each movable lever 3 is connected and driven to rotate through an operating handle 33. Thus, each movable lever 3 can be independently driven to switch positions according to needs, thereby improving the flexibility of use. The movable lever 3 is triggered by the operating handle 33, and the rotation of the movable lever 3 is completely controlled by the operator, which can avoid the problem of erroneous release when a fault or power failure occurs when an electric control method is used. The manual operating mechanism can drive multiple movable levers 3 to move at the same time, providing quick operation.

[0080] like Figure 2As shown, in a further preferred embodiment, the operating handle 33 is connected to any column 11 arranged on both sides along the in-and-out direction of the battery transport device 2 in the battery compartment 12. The operating handle 33 is arranged on the column 11 in the in-and-out direction of the battery compartment 12, so that the operator can easily access it and avoid the difficulty of operation caused by the position inside. In other embodiments, the operating handle 33 or other manual operating structure can be arranged above the battery rack 1. The manual operating mechanism on the top is easier to operate, does not occupy other space, and does not interfere with other motion mechanisms.

[0081] The present invention extends the movable lever on the travel channel of the battery transport device, and can be vertically positioned at a preset position by the movable lever when the battery transport device is being repaired, thereby providing a maintenance space and preventing the battery transport device from falling due to a fault caused by a circuit or control problem, thereby avoiding potential safety hazards and improving safety. At the same time, the blocking of the movable lever can ensure that the battery transport device will not fall, so the battery transport device no longer needs to be moved out of the travel channel. After the maintenance is completed, the operation can be resumed by simply removing the movable lever, thereby making the overall maintenance efficiency more efficient.

[0082] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
