[0002] With the continuous development of environmental issues and new energy technologies, new energy vehicles have gradually changed their original fuel methods and adopted batteries as driving energy, which has the advantages of zero emissions and low noise. The batteries of new energy vehicles need to be charged after the electricity is used up. For the batteries, the batteries can be removed for separate replacement and charging operations. After the replaced batteries are charged, they are installed in the new energy vehicles. Therefore, battery replacement stations are built to match new energy vehicles.

[0003] Battery swap stations for new energy vehicles (NEVs) utilize different types and sizes of battery packs, including sedans, SUVs, and trucks. These vehicles also vary in size, requiring different battery pack types and sizes. Consequently, these stations need to store battery packs of varying types and sizes to facilitate battery swaps, or they need to adjust the types of battery packs they store to accommodate different vehicle models and sizes. This requires battery racks to accommodate different battery pack types and sizes. Conventional battery racks are typically fixed structures, requiring pre-planning and customization to accommodate different battery pack types and sizes. This leads to high production costs and difficulty adjusting to changing conditions, resulting in poor versatility. Existing techniques also increase the battery rack compartment to improve versatility, but this increases the size of the rack, requiring more space within the station. Alternatively, the battery racks used to store these packs must be replaced simultaneously with the replacement of existing battery packs. This can be time-consuming to dismantle the existing racks and install new ones, significantly increasing equipment costs.

[0004] It can be seen that the existing technology still has certain defects, and there is an urgent need to design a battery rack that is easy to disassemble and adjust to meet the battery pack storage needs of battery swap stations. Utility Model Content

[0061] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0062] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific implementation methods disclosed below.

It is particularly suitable for battery storage devices in battery swap stations to improve the adaptability and adjustment capabilities of battery storage devices in battery swap stations, so as to meet the battery swap needs of different battery swap vehicles. It mainly includes multiple support columns 1 and multiple battery brackets 5. The multiple battery brackets 5 are arranged in the vertical direction. There are four support columns 1, and the end corners of each battery bracket 5 are connected to the corresponding support column 1 to provide support for each battery bracket 5. One of the support column 1 and the battery bracket 5 is provided with a mounting assembly, and the other is provided with a fastening assembly; along the vertical direction, multiple mounting assemblies or fastening assemblies are arranged at intervals on the support column 1, and the mounting assembly has a guide portion 21 and a locking portion 22, and the fastening assembly has a mating state and a releasing state relative to the mounting assembly; in the mating state, the fastening assembly is mated and fixed with the locking portion 22, so that the battery bracket 5 is fixed on the support column 1 to carry the battery pack, and in the releasing state, the fastening assembly can release the mating with the locking portion 22 and adjust its position along the guide portion 21 so that one of the fastening assemblies or the mounting assembly is adjusted relative to the other to achieve position adjustment of the battery bracket 5.

[0064] In the above scheme, the structure of the battery rack is relatively simple and easy to disassemble and install. That is, when the fastening assembly is in the released state, the battery bracket 5 and the support column 1 can be easily moved relative to each other, so as to facilitate the adjustment of the height position of the battery bracket 5 on the support column 1 so that the battery bracket 5 is in the best position to facilitate the storage of the battery pack; secondly, the spacing between adjacent battery brackets 5 can be further adjusted to adapt to the storage needs of battery packs of different sizes.

[0065] It should be noted that the present application does not specifically limit the configuration of the mounting assembly and the fastening assembly, and any of the following embodiments may be employed:

[0066] Embodiment 1: Multiple mounting assemblies are vertically spaced apart on the support column 1. A fastening assembly is mounted on the battery bracket 5, with the locking portion 22 communicating with the guide portion 21. The guide portions 21 of the multiple mounting assemblies are interconnected, and when released, the fastening assembly can move along the guide portion 21 to a locking portion 22 above or below the currently mounted assembly. This arrangement allows the battery bracket 5 to be adjusted without completely detaching from the mounting assembly, reducing disassembly workload. Furthermore, the guide portion 21 in the mounting assembly provides guidance for easy adjustment and positioning of the battery bracket 5.

[0067] The first embodiment is further described below by the following examples:

[0068] Example 1: Reference Figure 1-4 As shown, the guide portion 21 includes a horizontal groove 211 and a vertical groove 212 opened on the support column 1. The horizontal groove 211 extends in the horizontal direction and one end is connected to the locking portion 22, and the other end is connected to the vertical groove 212. The vertical groove 212 extends in the vertical direction and the vertical grooves 212 between adjacent installation components are connected so that the fastening component can move along the vertical groove 212 to another locking portion 22 in the released state. The fastening assembly includes a connecting portion 31 and an adjusting portion 32. One end of the connecting portion 31 is fixed to the battery bracket 5, and the other end is passed through the locking portion 22 and cooperates with the adjusting portion 32. The adjusting portion 32 can adjust the connection position with the connecting portion 31 to achieve a locked cooperation state of the connecting portion 31 and the locking portion 22 and a released state of the connecting portion 31 and the locking portion 22; wherein the width of the connecting portion 31 is smaller than the width of any one of the locking portion 22, the transverse groove 211, and the vertical groove 212, and the width of the adjusting portion 32 is larger than the width of any one of the locking portion 22, the transverse groove 211, and the vertical groove 212.

[0069] In the above scheme, the structure of the horizontal groove 211 and the vertical groove 212 is simple and easy to process, and can ensure that the fastening assembly can move from the horizontal groove 211 into the vertical groove 212 in the released state, so that the fastening assembly can quickly move along the vertical groove 212 to the other locking part 22 and cooperate, that is, the position of the battery bracket can be quickly adjusted without the fastening assembly being separated from the installation assembly; at the same time, in the above scheme, it is only necessary to adjust the connection position with the connecting part 31 through the adjustment part 32, and the cooperation relationship between the adjustment part 32 and the connecting part 31 can be achieved to achieve the cooperation state and the release state, so that the switching between the two states is convenient and fast, and the cooperation between the connecting part 31 and the adjustment part 32 is conducive to preventing the battery bracket 5 from falling directly off the support column 1 during the movement, and can provide a certain limiting guiding effect for the movement of the battery bracket 5, which is conducive to improving the assembly adjustment efficiency.

[0070] Furthermore, as a preferred embodiment of the present application, a first guide surface is provided at one end where the transverse groove 211 communicates with the vertical groove 212, and a second guide surface is provided at the point where the transverse groove 211 communicates with the locking portion 22. Preferably, the first guide surface and the second guide surface can be guide bevels or guide arcs. The provision of the guide bevels / guide arcs makes it easier for the fastening assembly to move relative to the guide portion 21, thereby improving the efficiency of adjusting and fixing the battery rack. Of course, the end where the transverse groove 211 communicates with the vertical groove 212 can also be provided with a bell mouth to facilitate the mating connection between the locking portion 22 and the transverse groove 211.

[0071] Embodiment 2: Multiple mounting assemblies are vertically spaced apart on the support column 1, and the fastening assembly is mounted on the battery bracket 5. The locking portion 22 communicates with the guide portion 21, and the guide portions 21 of the multiple mounting assemblies are isolated from each other. When released, the fastening assembly can move along the guide portion 21 and disengage from the mounting assembly, adjusting to engage with another locking portion 22 above or below the current mounting assembly. In this embodiment, the fastening assembly, guided by the guide portion 21, quickly disengages from the mounting assembly and can quickly adjust to engage with the locking portion 22 of another mounting assembly.

[0072] The second embodiment is further described below by way of examples:

[0073] Example 2: Reference Figure 5-7As shown, the guide portion 21 includes a mating groove 213 opened on the support column 1, and the upper end or the lower end of the mating groove 213 is connected to the locking portion 22. The fastening assembly can enter the mating groove 213 in a direction perpendicular to the vertical direction to move to the locking portion 22 connected to the mating groove 213 for mating or move out of the mating groove 213 to move to another locking portion 22 for mating. The fastening assembly includes a connecting portion 31 and an adjusting portion 32. One end of the connecting portion 31 is fixed to the battery bracket 5, and the other end is passed through the mounting assembly and cooperates with the adjusting portion 32.

In the above scheme, the structure of the matching groove 213 is simple and easy to process. The matching stroke between the connecting portion 31 and the matching groove 213 is shorter, which is conducive to improving the assembly and disassembly efficiency, thereby facilitating the position adjustment of the battery bracket 5. At the same time, the above scheme only requires adjusting the connection position with the connecting portion 31 through the adjusting portion 32, and the matching state and the release state can be achieved without releasing the matching relationship between the adjusting portion 32 and the connecting portion 31, making the switching between the two states convenient and fast.

[0074] Preferably, continue to refer to Figure 6 As shown, the mating groove 213 is preferably a circular groove, and the locking portion 22 is preferably a waist-shaped groove 221 disposed below and communicating with the circular groove. In conjunction with the waist-shaped groove 221, the opening area of ​​the circular groove is larger than the size of the adjustment portion 32, making it easier for the fastening assembly to enter and exit the circular groove, improving assembly and disassembly efficiency, and thus facilitating position adjustment of the battery bracket 5. The width of the connecting portion 31 is smaller than the width of the waist-shaped groove 221 and the circular groove, facilitating the fastening assembly to move between the waist-shaped groove 221 and the circular groove, thereby achieving engagement or disengagement of the fastening assembly with the locking portion 22 from the mating groove 213.

The plug-in plate 312 can move downward along the matching groove 213 to the position between the limit plate 223 and the support column 1 to achieve a matching state locked with the locking portion 22, and the plug-in plate 312 can move upward along the matching groove 213 to a released state from the locking portion 22.

[0077] In the above scheme, the matching groove 213 is preferably a rectangular groove, and the first bent plate 222 can be integrally formed with the matching groove 213 during the process of opening the matching groove 213, which is convenient for processing and saves cost. The integral formation of the first bent plate 222 and the matching groove 213 is conducive to improving the connection strength between the first bent plate 222 and the matching groove 213; the locking portion 22 is formed between the limit plate 223 and the support column 1, so that the matching and unlocking of the locking portion 22 and the fastening component are more convenient, and the need to set up additional fasteners or adjustment parts to achieve the locking connection between the fastening components is eliminated, and the need to operate the installation of fasteners or adjustment parts in the narrow operating hole on the side of the support column 1 facing away from the battery bracket 5 is eliminated. The time-consuming and labor-intensive operation steps such as fitting parts are more convenient for assembly and disassembly, which is beneficial to improving the adjustment efficiency of the battery bracket 5; the second bending plate 322 preferably has the same bending angle as the first bending plate 222. This structure can play a good guiding effect during the installation and disassembly of the battery bracket 5; the thickness of the plug-in plate 312 is not less than the distance between the limit plate 223 and the support column 1, that is, the thickness of the plug-in plate 312 is not less than the thickness of the previously locked part 22, so that the fit between the plug-in plate 312 and the locking part 22 can be tighter, avoiding the battery bracket 5 from loosening in the fitted state, and ensuring the stability of the connection between the battery bracket 5 and the support column 1.

[0078] Embodiment three: Multiple fastening components are arranged on the support column 1 at intervals along the vertical direction, the installation component is arranged on the battery bracket 5, the locking portion 22 is connected to the guide portion 21, and the guide portion 21 can move relative to the fastening component when the fastening component is in a released state so that the installation component is disengaged from the fastening component, and the locking portion 22 is adjusted to cooperate with another fastening component above or below the current fastening component.

[0079] In the above scheme, since the support column 1 usually has more available installation space than the battery bracket 5, compared with the first embodiment in which the fastening assembly is set on the battery bracket 5, the third embodiment in which the fastening assembly is set on the support column 1 can make full use of the installation space of the support column 1 to enhance the structural strength of the fastening assembly to improve its load-bearing capacity and will not increase the dead weight of the battery bracket 5 due to the setting of the reinforcement structure, thereby facilitating the stable setting of the battery on the support column 1; and in the third embodiment, the coordination and disassembly between the fastening assembly and the installation assembly are also simple and efficient.

[0080] The third embodiment is further described below by way of examples:

[0081] Example 4: Reference Figure 13-15 As shown, the guide portion 21 includes a mating groove 213 provided on the battery bracket 5, the upper end or the lower end of the mating groove 213 is connected to the locking portion 22, and the mating groove 213 is provided with an opening for the fastening component to enter the mating groove 213 and move to the locking portion 22 connected to the mating groove 213 for mating or move out of the mating groove 213 so that the locking portion 22 moves to another fastening component for mating. One end of the mating groove 213 connected to the locking portion 22 is set to a trumpet shape so that the width of the mating groove 213 is greater than the width of the locking portion 22, and the opening is set at the end of the mating groove 213 away from the locking portion 22 and / or at the side of the mating groove 213 away from the battery bracket 5; the fastening assembly includes a connecting portion 31 and an adjusting portion 32, one end of the connecting portion 31 is fixed on the support column 1, and the other end is passed through the mounting assembly and cooperates with the adjusting portion 32, and the adjusting portion 32 can adjust the connection position with the connecting portion 31 to achieve a locked mating state of the connecting portion 31 and the locking portion 22 and a released state of the connecting portion 31 and the locking portion 22.

[0082] Preferably, continue to refer to Figure 15 As shown, the mating groove 213 and the locking portion 22 are integrally formed, forming a V-shaped groove structure with an opening downward. The connecting portion 31 is preferably a connecting shaft 311 with an external thread, and the adjusting portion 32 is a locking nut 321 with an internal thread. The connecting shaft 311 passes through the side wall of the support column 1 and is locked with the locking nut 321, stably mounted on the support column 1. When the position of the battery bracket 5 needs to be installed or adjusted, it is only necessary to loosen the locking nut 321 to release the mounting assembly from the fastening assembly, and then move the battery bracket in the vertical direction to move the mounting assembly up or down to mate with another fastening assembly. The mounting assembly can then be mated with the fastening assembly by tightening the locking nut 321 again.

[0083] In the above scheme, the bell mouth setting makes it easier for the locking part 22 to be connected with the matching groove 213, which is beneficial to improving the matching efficiency; further, it is only necessary to adjust the connection position with the connecting part 31 through the adjusting part 32, and the matching state and the release state can be achieved without releasing the matching relationship between the adjusting part 32 and the connecting part 31, so that the switching between the two states is convenient and fast, and the setting of the opening facilitates the separation of the fastening component from the installation component, and the setting of the matching groove 213 facilitates the movement of the fastening component and provides a certain limiting guiding effect, which is beneficial to improving the assembly adjustment efficiency.

[0084] It should also be noted that the present application does not specifically limit the structure and setting method of the connecting portion 31 and the adjusting portion 32 in the embodiment. The above example is only a preferred example of the present application. The above connecting shaft 311 can also be directly welded to the support column 1 or integrally formed with the support column 1, thereby eliminating the setting of the adjusting portion 32, simplifying the matching / release operation, and saving costs. Of course, other more different settings can also be adopted. In this embodiment, the connecting portion adopts a connecting shaft 311 with an external thread and the adjusting portion adopts a locking nut 321 with an internal thread, which can also be applied to Examples 1 and 2, and the same method is used to achieve the matching state or release state between the mounting assembly and the fastening assembly.

Preferably, continue to refer to Figure 1 、 Figure 5 、 Figure 8 、 Figure 12 and Figure 13As shown, the connector 52 includes a first connecting plate 521 and a second connecting plate 522 connected at an angle, and the mounting assembly or fastening assembly is mounted on the first connecting plate 521 or the second connecting plate 522. When the battery bracket 5 is mounted on the support column 1, the first connecting plate 521 and the second connecting plate 522 are in contact with two adjacent side surfaces of the support column 1. The mating connection between the first connecting plate 521, the second connecting plate 522 and the two adjacent side surfaces of the support column 1 can expand the contact area between the connector 52 and the support column 1, improve the connection strength, and can achieve limited fixation in multiple directions, which is conducive to improving the connection strength and connection stability between the connector 52 and the support column 1, and further helps to ensure the stability of the position of the battery bracket 5 on the support column 1.

The blocking beam 512 and the support beam 511 jointly support the battery pack in the vertical direction; a reinforcement portion 513 is also provided at the connection between the support beam 511 and the first connecting plate 521 to enhance the connection strength between the support beam 511 and the first connecting plate 521 while enhancing the bearing capacity of the support beam 511 and the blocking beam 512. Preferably, the reinforcement portion 513 is a triangular reinforcement plate. Continue to refer to Figure 17 As shown, the guard beam 512 is arranged on the upper part of the support beam 511 in a detachable connection manner; along the direction of the battery pack entering and exiting, a plurality of mounting holes are provided on the support beam 511, and the guard beam 512 can be set at mounting holes at different horizontal distances from the support column 1 by bolt connection, thereby providing a better limiting effect for battery packs of different specifications and sizes in the direction of the battery pack entering and exiting, and preventing the battery pack from falling from the battery bracket 5 and being damaged.

[0088] The structure of the battery bracket 5 in this embodiment can be applied to any one of Examples 1-4.
