[0039] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0040] It should be noted that in the description of this application, terms such as "left" and "right" indicating direction or positional relationships are based on the direction or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] First refer to Figure 1 This paper provides a brief introduction to the stacker crane described in this application.

[0043] like Figure 1 As shown, to address the poor compatibility issue of stacker cranes in battery swapping stations, the stacker crane of this application includes a main frame 1, a transport frame 2, and two telescopic forks 3. The transport frame 2 is vertically and flexibly mounted on the main frame 1, and the two telescopic forks 3 are spaced apart on the transport frame 2, with at least one of the two telescopic forks 3 capable of moving along the distance between them. Each telescopic fork 3 has two support blocks 4 arranged along its length, and at least one of the support blocks 4 is capable of moving along its length.

[0044] In one possible application, the lifting and lowering movement of the transport frame 2 relative to the main frame 1 aligns it with the target battery on the battery rack. Then, both telescopic forks 3 extend simultaneously to the underside of the target battery. At this point, the transport frame 2 rises a certain height to lift the target battery. Immediately afterwards, the two telescopic forks 3 retract, moving the target battery out of the battery rack. Then, the transport frame 2 moves again to dock with the battery swapping robot and transfers the battery onto the robot. When the distance between the two telescopic forks 3 does not match the specifications of the target battery, the distance between the two telescopic forks 3 can be adjusted by changing the position of at least one telescopic fork 3 to match the specifications of the target battery. When the support block 4 on the telescopic fork 3 does not match the support point of the target battery, the support position of the support block 4 can be adjusted by changing the position of at least one support block 4 to place the support block 4 at or near the optimal support point of the target battery.

[0045] The stacker crane of this application, by setting at least one of the two telescopic forks 3 to be movable along the interval direction, can change the distance between the two telescopic forks 3, thereby enabling the stacker crane to adapt to batteries of different specifications and improving the compatibility of the stacker crane. By setting at least one of the two support blocks 4 on the telescopic fork 3 to be movable along the length direction of the telescopic fork 3, the support points of different battery models can be adjusted, improving the compatibility of the stacker crane and the battery load-bearing stability.

[0046] The following is combined with Figures 1 to 5 This paper describes a specific implementation of the stacker crane of this application.

[0047] like Figures 1 to 5 As shown, in one specific embodiment, the stacker crane includes a main frame 1, a transport frame 2, a telescopic fork 3, a support block 4, a first translation drive mechanism 51, a second translation drive mechanism 52, a telescopic drive mechanism 53, a first guide mechanism 61, and a second guide mechanism 62.

[0048] The main frame 1 is roughly rectangular and is movably set on the track 7 laid on the ground. The specific setting method and moving principle of the main frame 1 are conventional technical means in this field and will not be described in detail in this application.

[0049] The transport frame 2 is vertically and flexibly installed within the main frame 1. In this application, the transport frame 2 achieves vertical movement relative to the main frame 1 by a transmission belt driven by a motor. Since this is not the focus of this application, it will not be described in detail.

[0050] Reference Figures 2 to 5Each telescopic fork 3 includes a support rail 31, a slide 32, and a fork plate 33. The support rail 31 is slidably mounted on the transport frame 2, the slide 32 is slidably mounted on the support rail 31, and the fork plate 33 is slidably mounted on the slide 32. Two support blocks 4 are disposed on the upper side of the fork plate 33. A telescopic drive mechanism 53 is disposed on the support rail 31 and is configured to drive at least one telescopic fork 3 to extend or retract. In this application, the telescopic drive mechanism 53 specifically includes a third drive motor 531, a force transmission component 532, and two third transmission components 533. The third drive motor 531 is disposed on one of the support rails 31. Figure 2 The third drive motor 531 is connected to the third drive assembly 533 on the support rail 31 located on the upper left side. The third drive assembly 533 is also located on the support rail 31. Figure 2 The third transmission assembly 533 on the lower right support rail 31 is connected to the third drive motor 531 via the force transmission assembly 532. The third transmission assembly 533 is a chain drive assembly, which is arranged between the support rail 31, the slide 32, and the fork 33. When the chain drive assembly is activated, it can drive the slide 32 and the fork 33 to move simultaneously in one direction, thereby realizing the three-stage extension and retraction of the telescopic fork 3. The force transmission assembly 532 includes a gear set and a splined shaft. The output end of the third drive motor 531 is simultaneously connected to the gear set and a third transmission assembly 533. One end of the splined shaft is connected to the last gear of the gear set, and the other end is connected to another third transmission assembly 533. This third transmission assembly 533 can translate along the splined shaft to avoid affecting the translation of the telescopic fork 3.

[0051] Thus, when the third drive motor 531 is activated, a portion of the motor's output torque is transmitted to the third transmission component 533 connected to it, which in turn drives the corresponding slide 32 and fork 33 to move simultaneously. The other portion of the motor's output torque is transmitted to another third transmission component 533 through the force transmission component 532, which in turn drives its corresponding slide 32 and fork 33 to move simultaneously, ultimately achieving synchronous extension and retraction of the two telescopic forks 3.

[0052] The third drive motor 531 simultaneously drives two third transmission components 533, which can save the number of drive motors, save internal space of the transport frame 2, and facilitate the synchronous extension and retraction of the two telescopic forks 3.

[0053] Reference Figure 2 and Figure 4Each telescopic fork 3 has two support blocks 4 that can move along the length of the telescopic fork 3. Taking one telescopic fork 3 as an example, specifically, the two support blocks 4 move closer or further apart through a first translation drive mechanism 51. The first translation drive mechanism 51 includes a first drive motor 511 and two first transmission assemblies 512. The first drive motor 511 is a geared motor, which is fixedly installed on the side of the fork plate 33. In this embodiment, the first transmission assembly 512 is a transmission chain group. The output end of the first drive motor 511 is connected to both transmission chain groups simultaneously. Each transmission chain is fixedly connected to a support block 4. Each support block 4 is slidably connected to the telescopic fork 3 through a first guide mechanism 61. In this application, the first guide mechanism 61 is a slider rail assembly, wherein the rail is fixedly connected to the upper side of the fork plate 33, and the slider is fixedly connected to the bottom of the support block 4.

[0054] Thus, when the first drive motor 511 starts, it simultaneously drives the two transmission chain groups to move, and the two transmission chain groups drive the two support blocks 4 to move closer or further apart under the guidance of the first guide mechanism 61.

[0055] Both support blocks 4 can move along the length of the telescopic fork 3, which can increase the adjustment range and further improve the compatibility of the stacker crane. By setting the first translation drive mechanism 51, the support blocks 4 can be automatically adjusted, improving the adjustment accuracy and automation level. The setting of the first guide mechanism 61 can improve the movement stability of the support blocks 4.

[0056] Reference Figure 2 , Figure 3 and Figure 5 Both telescopic forks 3 can move along the interval between them. Specifically, each of the two telescopic forks 3 is moved along the interval between them via a second translation drive mechanism 52 (i.e., Figure 2 (The direction perpendicular to the length of the telescopic fork 3). The second translation drive mechanism 52 includes a second drive motor 521 and a second transmission assembly 522. The second drive motor 521 is fixedly connected to the transport frame 2. In this embodiment, the second transmission assembly 522 is a gear and rack assembly. The output end of the second drive motor 521 is connected to the gear in the gear and rack assembly, and the rack in the gear and rack assembly is connected to the support rail 31. Each support rail 31 is provided with two front and rear second guide mechanisms 62 along its length direction. The second guide mechanism 62 is a slide rail slider assembly. The slide rail is fixedly connected to the transport frame 2, and the slider is fixedly connected to the lower side of the support rail 31.

[0057] Thus, when the two second drive motors 521 are started, the two telescopic forks 3 can move along the distance between them, such as moving away from or closer to each other, through the transmission of the gear rack and the guiding action of the second guide mechanism 62.

[0058] The ability of both telescopic fork arms 3 to move increases the spacing adjustment range and further enhances the compatibility of the stacker crane. By incorporating a second translation mechanism, automated adjustment of the telescopic fork arms 3 can be achieved, improving the level of automation and adjustment accuracy. Furthermore, the second guide mechanism 62 enhances the stability of the telescopic fork arms 3's movement.

[0059] It should be noted that the above preferred embodiments are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can adjust the above settings to make this application applicable to more specific application scenarios.

[0060] For example, in an alternative embodiment, although the above embodiment is described with the example of both telescopic forks 3 being movable, this is not restrictive. Those skilled in the art can adjust it as long as the condition that at least one telescopic fork 3 can be moved is met.

[0061] For example, in another alternative embodiment, the arrangement in which both support blocks 4 are movable is merely exemplary. In other embodiments, those skilled in the art can adjust it so that one support block 4 is fixed while the other support block 4 is movable.

[0062] For example, in another alternative embodiment, the telescopic fork 3 is described as a three-section telescopic example. However, the number of telescopic sections of the telescopic fork 3 is not unique. Based on different application scenarios, those skilled in the art can also change the telescopic fork 3 to other telescopic forms, such as two-section or four-section.

[0063] For example, in another alternative embodiment, the specific arrangement of the first translation drive mechanism 51 is not restrictive, and those skilled in the art can adjust it based on specific application scenarios. For instance, in addition to the specific forms described above, it can also be replaced with an electric cylinder, an electric push rod, or a drive motor connected to the support block 4 via a synchronous belt, gear rack, lead screw nut, or other transmission methods. Furthermore, the arrangement of the first translation drive mechanism 51 is not mandatory, and the movement of the support block 4 can also be achieved manually.

[0064] For example, in another alternative embodiment, the arrangement of the second translation drive mechanism 52 is not fixed. Provided that the translation of the telescopic fork 3 can be achieved, those skilled in the art can adjust the specific form of the second translation drive mechanism 52. For instance, only one second translation drive mechanism 52 can be provided, with the two telescopic fork 3 moved by a motor simultaneously driving two transmission components. For example, the motor can drive the two telescopic fork 3 through a double rack and pinion, a double chain assembly, a double synchronous belt, a double lead screw and nut, etc. Furthermore, when each telescopic fork 3 is driven by one second translation drive mechanism 52, the specific arrangement of the second transmission component 522 is not fixed. Besides rack and pinion, the second transmission component 522 can be replaced with a chain assembly, a synchronous belt, a lead screw and nut pair, etc. Alternatively, the second translation drive mechanism 52 can be directly set as an electric cylinder, an electric push rod, etc.

[0065] For example, in another alternative embodiment, the specific arrangement of the telescopic drive mechanism 53 is not restrictive. Although the above embodiment is described in conjunction with the example of simultaneously driving two telescopic forks 3 to extend and retract via a third drive motor 531, this is only one possible embodiment, which is advantageous for saving space and motors. Those skilled in the art will understand that in other embodiments, each telescopic fork 3 can also be provided with a drive mechanism to achieve separate control of the two telescopic forks 3. Of course, this arrangement is not conducive to the synchronous control of the telescopic forks 3.

[0066] In another alternative embodiment, the specific forms of the first guide mechanism 61 and the second guide mechanism 62 are not fixed. Although the above embodiments are all described with reference to the slider-rail assembly, those skilled in the art can also use the slider-rail assembly, the rail-slide assembly, etc., as substitutes. Of course, setting the first guide mechanism 61 and the second guide mechanism 62 is only a more reliable embodiment, and those skilled in the art can selectively omit at least one of the two guide mechanisms.

[0067] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0068] This application also provides a battery swapping station, which includes the stacker crane described in the above embodiments.

[0069] The battery swapping station of this application, by setting up the aforementioned stacker crane, can accommodate batteries of different specifications, thereby improving the compatibility and load-bearing stability of the stacker crane.

[0070] The following describes one possible battery swapping process for the battery swapping station of this application.

[0071] In one possible implementation, the battery swapping station includes a battery swapping platform, a battery swapping robot, a battery rack, and a stacker crane. Before battery swapping begins, the station obtains the battery model of the vehicle to be swapped and then determines whether the distance between the two telescopic forks 3 of the stacker crane and the current position of the four support blocks 4 match the battery model. If they do not match, the station controls the first translation drive mechanism 51 and the second translation drive mechanism 52 to adjust the distance between the two telescopic forks 3 and the position of the four support blocks 4. During the battery swapping process, the vehicle to be swapped is parked on the battery swapping platform. The battery swapping robot moves to the bottom of the vehicle to remove the depleted battery. The battery swapping robot then carries the depleted battery to the stacker crane and delivers it to the two telescopic forks 3 of the stacker crane. The stacker crane then aligns with an empty space on the battery rack by moving the main frame 1 and raising and lowering the transport frame 2 along the main frame 1. At this point, the two telescopic forks 3 extend and place the depleted battery in the empty space. After placement, the two telescopic forks 3 retract. Then, by moving the main frame 1 relative to the base and raising / lowering the transport frame 2 relative to the main frame 1, alignment with a fully charged battery on the battery rack is achieved. The two telescopic forks 3 then extend to carry the fully charged battery, and subsequently retract. The main frame 1 moves, and the transport frame 2 rises / lowers, to dock with the battery swapping robot, transferring the fully charged battery to it. Finally, the battery swapping robot, carrying the fully charged battery, moves again to the area under the vehicle to be swapped and installs the battery on the vehicle.

[0072] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0073] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
