Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically to a battery pack loading device. Background Technology

[0002] A battery pack is a device used to store and manage electrical energy, typically integrated within an energy storage cabinet or container. It stores electrical energy through battery packs and converts direct current (DC) to alternating current (AC) via an inverter when needed, supplying power to external devices. Battery packs are widely used in renewable energy storage, grid peak shaving and frequency regulation, and industrial backup power, featuring modularity, high safety, and strong environmental adaptability.

[0003] After the battery pack assembly is completed, it needs to be placed into an energy storage cabinet or container. The traditional installation method usually involves multiple workers working together to lift the battery pack and place it into the support frame inside the energy storage cabinet or container. A special fixing device is then used to secure the battery pack inside the energy storage cabinet or container. During the installation process, it is necessary to ensure that the battery pack is not squeezed or bumped by external forces to avoid affecting the internal components of the battery pack. However, this installation method requires a lot of manpower and has low actual installation efficiency. In addition, due to the large weight of a single battery pack, worker safety cannot be guaranteed during the installation process. Therefore, a battery pack placement device is proposed.

The side-shifting unit can drive the support frame to move along the first direction to approach the battery pack installation position of the container or energy storage cabinet. The deflection unit can drive the second frame to rotate relative to the first frame to align the battery pack with the installation position.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0055] Figure 1 This is a perspective view of a battery pack transfer device according to one embodiment of this application. The battery pack transfer device can be used for battery pack transfer and includes: a base 1 configured to be movable to the side of the battery pack mounting position via a transfer device; a support frame 2 including at least a first frame 21 slidably mounted on the top of the base 1 along a first direction and a second frame 22 rotatably mounted on the top of the first frame 21 for supporting the battery pack; a lateral shifting unit 3 disposed on the base 1 and configured to drive the support frame 2 to move along the first direction to approach the mounting position; a deflection unit 4 disposed between the first frame 21 and the second frame 22 and configured to drive the second frame 22 to rotate relative to the first frame 21 to align the battery pack with the mounting position; and a feeding unit 5 disposed on the second frame 22 and configured to drive the battery pack to reciprocate along a second direction to move it into or out of the mounting position.

[0056] refer to Figures 1-5 In this arrangement, during the actual installation of the battery pack, the battery pack is first placed on top of the second frame 22. Then, the device is moved to the side of the installation position close to the battery pack by an external transfer device. The side-shifting unit 3 can drive the support frame 2 to move along the first direction to approach the battery pack installation position of the container or energy storage cabinet. The deflection unit 4 can drive the second frame 22 to rotate relative to the first frame 21 to align the battery pack with the installation position. Finally, the feeding unit 5 drives the battery pack to reciprocate along the second direction to move it into or out of the installation position. This achieves automatic loading or unloading of the battery pack, improving the efficiency of battery pack installation or disassembly while effectively saving labor costs and meeting the installation and maintenance needs of the battery pack.

[0057] The following will illustrate further specific implementations or refinements of the board enclosure assembly through exemplary description, in order to further improve it or for other improvement considerations.

[0058] Based on this, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The feeding unit 5 includes: at least one guide rail 51 configured to be mounted on the second frame 22 and extending along a second direction; a push-pull member 52 slidably mounted on the guide rail 51 and configured to abut against the battery pack to move it into the mounting position; and a drive module 53 disposed on the second frame 22 and configured to drive the push-pull member 52 to reciprocate along the guide rail 51.

[0059] Further reference Figure 3 and Figure 4 The device further includes at least one slide rail 6 that extends along a first direction, the slide rail 6 being fixedly mounted above the base 1, and the bottom of the first frame 21 being slidably connected to the slide rail 6 via a slider.

[0060] It can be seen that by setting the guide rail 51 extending along the second direction, the moving accuracy of the battery pack is further improved. The slide rail 6 extends along the first direction to support the sliding of the first frame 21; the guide rail 51 extends along the second direction to support the reciprocating motion of the battery pack.

[0061] Specifically, the slide rail 6 provides a stable sliding path for the first frame 21, ensuring that the support frame 2 will not deviate during lateral movement, while the guide rail 51 ensures that the push-pull component 52 reciprocates along a straight line.

[0062] Furthermore, the feeding unit 5 also includes at least one hooking member (not shown in the figure), which is configured to be fixed at one end to the push-pull member 52 and hooked at the other end to the battery pack to move it out of the mounting position.

[0063] In this arrangement, the feeding unit 5 uses the push-pull component 52 and the hook-up component to accurately push and pull out the battery pack, ensuring the efficiency of the installation and disassembly process. The push-pull component 52 can push the battery pack into the installation position, while the hook-up component can pull the battery pack out of the installation position after manual assistance, realizing a two-way operation function. The integrated design of the hook-up component and the push-pull component 52 simplifies the overall structure and facilitates maintenance and use. The drive module 53 can precisely control the position of the push-pull component 52, thereby facilitating the adaptation to battery packs of different sizes.

[0064] Furthermore, refer to Figure 1 , Figure 5 and Figure 6 The drive module 53 includes: a first drive member 531 fixedly installed on the first frame 21, a first lead screw 532 configured to be connected to the output end of the first drive member 531 and extending along a second direction, and a first adapter 533 configured to be threadedly connected to the first lead screw 532 and fixedly installed on the bottom of the push-pull member 52.

[0065] It can be seen that the drive module 53 includes a first drive component 531, a first lead screw 532 and a first adapter 533. The push-pull component 52 is driven by the first lead screw 532 to reciprocate along the guide rail 51. Under the combined action, the push-pull component 52 can run smoothly on the guide rail 51. The combination of the first drive component 531 and the first lead screw 532 is simple and reliable, and can work stably for a long time, ensuring that the battery pack can move smoothly in a straight line during the process of entering the box.

[0066] In actual operation, this embodiment should be referred to Figure 1 and Figure 5 The push-pull member 52 is provided with a push lug 54 on the side that contacts the battery pack. The push lug 54 is configured as two and symmetrically distributed at both ends of the push-pull member 52 along the first direction.

[0067] It can be seen that by setting the push lug 54 on the push-pull member 52, the friction between the battery box and the push-pull member 52 is increased, making the battery pack more stable during the pushing process.

[0068] Furthermore, the push-pull member 52 is configured as a push plate, and the hooking member is configured as a hook chain and symmetrically installed at both ends of the push plate along the first direction.

[0069] It is easy to see that by setting the push-pull component 52 as a push plate and the hook component as a hook chain, the battery pack can be firmly gripped, preventing it from slipping during movement and ensuring the operational stability of the push-pull component 52. In addition, setting the hook component as a hook chain and symmetrically arranging it at both ends can ensure more stable pulling back of the battery pack. The design of the push plate and hook chain can also be applied to battery packs of various specifications, improving the versatility of the device.

[0070] For example, the first driving component 531 can be a stepper motor or a servo motor, the push-pull component 52 can be replaced by a gripper mechanism or a vacuum suction cup, and the hanging component can be extended to a wire rope or a steel strip. All of these can be selected as needed, and this embodiment does not make specific limitations here.

[0071] Further reference Figure 2 , Figure 3 and Figure 4The lateral shifting unit 3 includes: a second driving member 31 fixedly installed on the base 1, a second lead screw 32 configured to extend along a first direction and connected to the output end of the second driving member 31, and a second adapter 33 fixedly installed on the bottom of the first frame 21 and configured to be threadedly connected to the second lead screw 32.

[0072] It is easy to see that by setting the side shift unit 3, it is convenient to drive the second lead screw 32 to rotate through the second drive member 31. Since the bottom of the first frame 21 is fixed with the second adapter 33, the first frame 21 can be driven to slide along the slide rail 6 through the second adapter 33, so as to realize the overall movement of the first frame 21 and the second frame 22 relative to the base 1, and drive the two to move along the first direction and approach the installation position.

[0073] For example, the second driving component 31 can be a drive motor, and the second adapter 33 can be an adapter block. Of course, the side-shifting unit 3 can also be a translation driving device such as a cylinder or a hydraulic rod, as long as it can realize the translation function. This embodiment does not make specific limitations here.

[0074] Furthermore, refer to Figure 7 and Figure 8 The deflection unit 4 includes: a support frame 41 fixedly installed on one side of the second frame 22 near the battery pack to be transferred; and a deflection cylinder 42 configured such that its output end is rotatably connected to the support frame 41 and its opposite end is fixedly connected to the top of the first frame 21. The deflection cylinder 42 forms a certain angle with the support frame 41 and is configured to drive the second frame 22 to rotate relative to the first frame 21 by extension and retraction.

[0075] It can be understood that the lateral shifting unit 3 can drive the support frame 2 to move along the first direction to approach the battery pack installation position of the container or energy storage cabinet, while the deflection unit 4 can drive the second frame 22 to rotate relative to the first frame 21 to achieve alignment between the battery pack and the installation position.

[0076] Specifically, the deflection cylinder 42 can change the angle of the second frame 22 relative to the first frame 21 through its extension and retraction action, thereby achieving precise alignment of the battery pack. The deflection cylinder 42 has a rapid start-stop effect, which can improve the operating efficiency of the device. The combination design of the support frame 41 and the deflection cylinder 42 is simple and easy to maintain, and has strong practicality.

[0077] For example, the first frame 21 and the second frame 22 are rotatably connected at their center positions by bearings, and the top of the first frame 21 is provided with at least one universal joint for assisting in supporting the rotation of the second frame 22.

[0078] It can be seen that, through the combined action of the bearing and the universal joint, the second frame 22 can rotate freely relative to the first frame 21 in the horizontal plane, which facilitates the alignment of the battery pack. The universal joint can be used to assist in supporting the second frame 2 and prevent the second frame 22 from shaking or tilting during rotation.

[0079] In actual operation, this embodiment should be referred to Figures 1-5 It also includes a fork-connecting unit 7 and a rolling unit 8. The fork-connecting unit 7 is disposed at the bottom of the base 1 and is configured to allow forklift rods to be inserted to move the base 1 to the side of the mounting position. The rolling unit 8 is disposed at the top of the second frame 22 and is configured to allow the battery pack to be pressed.

[0080] It can be seen that by setting the fork-connecting unit 7, the device can be used with a forklift, which facilitates handling and loading / unloading in confined spaces. By setting the rolling unit 8, friction is reduced, making the battery pack move more smoothly in and out of the installation position.

[0081] Furthermore, the fork unit 7 is configured as four groups and is distributed on the four sides of the base 1, with each group having two parallel and spaced forklift slots 71.

[0082] It is easy to see that by setting the fork-connecting units 7 into four groups and correspondingly distributing them on the four sides of the base 1, each group of fork-connecting units 7 includes two parallel forklift slots 71, which facilitates connection with the forklift rod through the forklift slots 71 near the outer edge, thereby enabling the entire device to be lifted or lowered, and thus realizing the transfer of the battery pack before it is put into the box, saving manpower and making the operation more stable.

[0083] It should be noted that the design of the four forklift slots 71 allows forklifts to approach the device from any direction, enabling the loading and unloading of battery packs inside the energy storage cabinet or container within a small space. This eliminates the need to reserve a lot of installation space between adjacent containers, effectively reducing the distance between adjacent energy storage cabinets or containers. This facilitates maintenance while also increasing the number of energy storage cabinets per unit area and reducing the overall footprint cost of the energy storage cabinet.

[0084] In one embodiment, reference is made to... Figure 5 and Figure 7 The rolling unit 8 includes at least two sets of transverse rollers 81 arranged at both ends of the second frame 22 along a first direction for receiving the battery pack, and each set of transverse rollers 81 extends along a second direction.

[0085] It can be understood that by setting the rolling unit 8 as a transverse roller 81 extending along the second direction, it is convenient for the battery pack to be pressed to reduce the friction during its movement, making it easier for it to enter or exit the mounting position. In addition, the transverse roller 81 extending along the second direction can guide the battery pack to slide along a predetermined trajectory to avoid deviating from the preset movement direction.

[0086] In another embodiment, reference is made to... Figure 9 This is a structural diagram of the battery pack placement device of this application. Specifically, it also includes lateral rollers 9 arranged on the inner walls of both sides of the second frame 22 along the first direction and used to limit the battery pack.

[0087] It is easy to see that by using the lateral rollers 9 arranged on the inner walls of both sides of the second frame 22, the position of the battery pack can be effectively constrained, preventing it from shifting during movement. Moreover, the rollers are made of soft material and will not scratch the battery pack, thus effectively limiting the shift of the battery pack.

[0088] For example, the lateral roller 9 is installed parallel to the vertical plane, which is compatible with the general cubic shape of the battery pack. Of course, the lateral roller 9 can also be installed at a certain angle relative to the vertical plane to adjust the shape of the battery pack. This embodiment does not make specific limitations here.

[0089] Specifically, refer to Figure 1 and Figure 9 During the actual installation of the battery pack, the battery pack is first placed on top of the second frame 22, and then moved to the side of the energy storage cabinet / container near the battery pack installation position by an external transfer device (such as a forklift). The side-moving unit 3 drives the support frame 2 to move along the first direction to approach the battery pack installation position of the container / energy storage cabinet. The deflection unit 4 can drive the support frame 2 to move along the horizontal direction to align the battery pack with the installation position. Finally, the feeding unit 5 drives the battery pack to reciprocate along the second direction to move it into or out of the installation position. This achieves automatic loading or unloading of the battery pack, improving the efficiency of battery pack installation or disassembly while effectively saving labor costs and meeting the installation and maintenance needs of the battery pack.

[0090] Meanwhile, through this loading device, combined with the bottom forklift slot 71, the battery packs inside the energy storage container can be loaded and unloaded in a small space, effectively reducing the distance between adjacent energy storage cabinets, facilitating maintenance, increasing the number of energy storage cabinets per unit area, and reducing the equipment's footprint cost.

[0091] The above examples primarily illustrate the battery pack loading device of this application. Although only some embodiments of this application have been described, those skilled in the art should understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are considered illustrative rather than restrictive, and this application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of this application.
