Technical Field

[0001] This application belongs to the field of battery swapping technology, specifically relating to a segmented battery swapping box and vehicle. Background Technology

[0002] Currently, electric heavy-duty trucks in my country mainly operate on two models: charging and battery swapping. Battery swapping heavy-duty trucks have a movable and detachable battery housing mounted on the battery base.

[0003] In existing technologies, the battery box structure of battery-swapping heavy-duty trucks is constructed using a one-piece welded steel structure. When the battery capacity varies, the size of the battery box also differs, requiring a redesign and remanufacturing of the corresponding battery box.

[0004] Currently, the most widely used battery swapping enclosures in the market have capacities of 280kWh and 350kWh, using 8 and 10 standard battery packs respectively. Because of the different number of battery packs, separate battery enclosures of corresponding sizes need to be designed and manufactured, and each model requires its own warehouse inventory. Manufacturers cannot predict the order quantity for each model of battery enclosure, and different models need to be stocked simultaneously, leading to high inventory pressure, tight cash flow, and other problems, placing significant pressure on company operations.

[0014] A second connecting plate is provided on the top edge of the middle frame near the upper frame; the first connecting plate and the second connecting plate are positioned opposite each other;

[0015] The first connecting plate and the second connecting plate are detachably connected by bolts.

[0016] Optionally, the middle frame has a plurality of first through holes on the first crossbar near the bottom frame; a first stud is welded into the first through hole;

[0017] The bottom frame has multiple second through holes on the second crossbar near the middle frame; a second stud is welded into the second through hole.

[0018] When the middle frame and the bottom frame are connected, each of the first studs is aligned with a second stud, and the first studs and the second studs are fastened together by bolts.

[0019] Optionally, the bottom frame is provided with connectors; the bottom frame also includes an integrated connector mounting plate or a non-integrated connector mounting plate; the integrated connector mounting plate is used to connect with an integrated connector, and the non-integrated connector mounting plate is used to connect with a non-integrated connector.

[0020] The integrated connector mounting plate is detachably mounted on the bottom frame via the connector, or the non-integrated connector mounting plate is detachably mounted on the bottom frame via the connector.

[0021] Optionally, when the integrated connector movable mounting plate is installed on the bottom frame, the target accessory is installed on the bottom frame.

[0022] Optionally, the target accessory includes at least one of: a battery management module and a cooling component;

[0023] Optionally, it also includes a housing;

[0024] The outer shell encloses the upper frame (excluding the hoisting section), the bottom frame, and the middle frame.

[0025] In a second aspect, this application discloses a battery box, including a segmented battery swapping box as described in any of the first aspects.

[0026] The target accessory is installed in the accessory mounting section of the upper frame;

The bottom and middle frames are interchangeable across different battery enclosure models; only the dimensions of the upper frame need to be changed for battery enclosures with different capacities. When meeting a 280 kWh capacity requirement, the upper frame is only used for hoisting and installing accessories, and does not house standard battery packs. When meeting a 350 kWh capacity requirement, two standard battery packs can be installed in the upper frame, with other kilowatt-hour components such as water-cooled units installed inside the dedicated 350 kWh upper section. This way, only the corresponding upper module needs to be replaced to meet the requirements of battery enclosures with different capacities, without needing to replace the bottom and middle frames. Manufacturers do not need to stock the entire battery enclosure; the bottom and middle frames for different battery enclosure models can share inventory, requiring only separate stocking of the corresponding upper frame. This reduces inventory pressure for companies and facilitates standardized production.

[0032] The battery box and the vehicle have the same beneficial effects as the segmented battery swapping box described above, and will not be repeated here.

[0033] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the fixed scope of the present utility model.

[0056] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0057] Electric heavy-duty trucks are charged and discharged via electrical connectors installed inside the battery housing. The battery capacity of the housing is determined by the number of battery packs installed. Currently, the most widely used battery housing specifications are 280kWh and 350kWh, using 8 and 10 standard battery packs respectively. Due to the different number of battery packs, different specifications of battery housings also differ. Traditional battery housings mainly adopt an integrated welded tubular structure, internally housing the battery powertrain and its accessories. Once the structure is finalized, its adaptability is relatively limited, requiring overall production, stocking, assembly, and transportation. Furthermore, integrated welding manufacturing has stringent dimensional accuracy requirements, and due to the large size, machining costs are high. In actual production and operation, battery housing manufacturers cannot predict order quantities and must stock simultaneously, leading to high inventory pressure, tight cash flow, and other problems, placing significant pressure on company operations.

[0058] To address the aforementioned technical problems, embodiments of this application provide, as follows: Figure 1 and Figure 2 A segmented battery swapping housing, as shown, includes: an upper frame 10, a middle frame 20, and a bottom frame 30; the upper frame 10 is detachably connected to the middle frame 20, and the upper frame 10 includes a first upper frame 11 or a second upper frame 12; the first upper frame 11 includes a lifting section and an accessory mounting section; the second upper frame 12 includes a lifting section, an accessory mounting section, and a battery mounting section; the lifting section is used for a lifting mechanism to lift the segmented battery swapping housing, the accessory mounting section is used for installing target accessories 40, and the battery mounting section is used for... Battery pack 50 is installed; when the first upper frame 11 is detachably connected to the middle frame 20, the power of the segmented battery swapping box meets the first power requirement; when the second upper frame 12 is detachably connected to the middle frame 20, the power of the segmented battery swapping box meets the second power requirement; the middle frame 20 is detachably connected to the bottom frame 30, and the middle frame 20 is used to install battery pack 50; the bottom frame 30 is used to detachably connect to the vehicle base 200, and the bottom frame 30 is used to install battery interface components.

[0059] In this embodiment, the battery box is functionally divided into an upper frame 10, a middle frame 20, and a bottom frame 30. These three parts are detachably connected together and fixed with bolts. The bottom frame 30 is then mounted on the vehicle base 200 and connected to the electrical interface and cables on the vehicle base 200 to supply power to the battery-swapping heavy truck. The upper frame 10 has a lifting section with a protruding surface at the top. Metal rings are welded to the four ends of the top surface of the upper frame 10 to provide overall gripping functionality. A bracket is set inside the frame for installing target controls such as water-cooled units, battery management modules, and junction boxes, and can also be used to install part of the battery pack 50. The middle frame 20 is used to install the battery pack 50, and the cables passing through the bottom frame 30 are electrically connected to the battery pack 30. The bottom frame 30 is used to install the battery swapping connector, provides space for electrical interfaces and cables, and serves as a connection point to the vehicle base 200.

[0060] The upper frame 10, middle frame 20, and bottom frame 30 can be manufactured independently. During use, the corresponding model is selected and assembled according to the battery box capacity. The upper frame 10 and middle frame 20, and the middle frame 20 and bottom frame 30 are sequentially fastened together with bolts. A skin is then applied to the frame surface to form a complete battery box. The upper frame 10 is lifted onto the vehicle-mounted base 200 on the battery swapping truck. A mechanical locking mechanism is installed between the bottom frame 30 and the vehicle-mounted base 200 to secure the battery box. When the battery box needs to be replaced, the entire box is simply transferred from the vehicle-mounted base 200.

[0061] Specifically, the main structure of the battery box is made of QSTe700 material, featuring high-strength tubular beams that are both strong and lightweight, enhancing the box's overall strength. The bottom frame 30 and middle frame 20 are universally compatible with battery boxes ranging from 210°C to 500°C. In this embodiment, the heights H1 of the bottom frame 30 and H2 of the middle frame 20 are fixed, while the height H3 of the upper frame 10 is adjusted according to the battery capacity. The bottom frame 30 serves as the connection point for the battery box structure and cables, and is compatible with all battery box models when a suitable vehicle mount 200 is available. The middle frame 20 can accommodate a fixed number of 8 standard battery packs. When the battery capacity exceeds the capacity provided by 8 standard battery packs 50, requiring an additional number of battery packs 50, a corresponding battery mounting section is added to the upper frame 10 to install the corresponding number of battery packs 50. By changing the size of the upper frame 10, different numbers of battery packs 50 can be accommodated to meet the requirements of different battery box models. In actual production, the upper frame 10 is the lightest and occupies the least space. Replacing the upper frame 10 has the least impact on the manufacturer's inventory pressure. Moreover, the disassembly and installation of the upper frame 10 is the simplest during assembly.

[0062] Currently, the most widely used battery swapping enclosures in the market have capacities of 280 kWh and 350 kWh. A standard battery pack (50) has a capacity of 35 kWh, and the two models use 8 and 10 standard battery packs (50) respectively. This application uses the 280 kWh and 350 kWh battery enclosures as examples for illustration.

[0063] like Figure 3 As shown, when meeting the 280 kWh power requirement (the first power requirement), the battery casing includes a bottom frame 30, a middle frame 20, and a first upper frame 11. Eight battery packs 50 are installed in the middle frame 20, and other mounting components such as the water-cooled unit are installed in the first upper frame 11 via mounting brackets. The first upper frame 11 only serves to install the target accessory 40 and for hoisting. At this point, the upper layer is the accessory installation space, the middle layer is the power battery installation space, and the lower layer is the docking interface installation space.

[0064] like Figure 4 As shown, when meeting the 350 kWh power requirement (the second power requirement), the battery casing includes a bottom frame 30, a middle frame 20, and a second upper frame 12. Eight battery packs 50 are installed in the middle frame 20, and two standard PACK battery packs 50 are installed in the battery mounting section added to the second upper frame 12. Other mounting components, such as the water-cooling unit, are installed on top of the second upper frame 12. At this point, the middle section remains the power battery mounting space, the lower layer is the docking interface mounting space, and the upper layer serves as both accessory mounting space and power battery mounting space.

[0065] In the two different specifications of battery boxes mentioned above, the bottom frame 30 and the middle frame 20 are completely identical, requiring only the replacement of the matching upper frame 10. This allows for modular design and assembly of the battery box, facilitating simple disassembly and replacement. It can meet the needs of the most commonly used 280kWh and 350kWh battery boxes on the market as much as possible. In actual production and inventory preparation, the order quantity for various models cannot be accurately estimated. To respond to customer orders and deliver goods as quickly as possible, it is necessary to prepare inventory in advance. However, preparing inventory for the entire battery box requires a large amount of storage space, increasing operating costs. In this embodiment, the segmented battery box design allows the larger bottom and middle frames to be used for various models. Different battery box models differ only in the upper frame, which occupies the least space. Preparing inventory only for the upper frame maximizes space savings. Using the segmented battery box design in this embodiment avoids duplicate inventory preparation due to unpredictable order quantities, improves production efficiency, and reduces the manufacturer's inventory pressure.

[0066] In addition, such as Figure 5 - Figure 7As shown, in some optional embodiments, the upper frame 10 is provided with a plurality of protruding sections near the middle frame 20; the plurality of protruding sections are of the same length, and the end of the protruding section near the middle frame 20 is provided with a first connecting plate 13; a second connecting plate 24 is provided on the top edge of the middle frame 20 near the upper frame 10; the first connecting plate 13 and the second connecting plate 24 are positioned correspondingly; the first connecting plate 13 and the second connecting plate 24 are detachably connected by bolts.

[0067] Furthermore, such as Figure 8 - Figure 10 As shown, the middle frame 20 has a plurality of first through holes 22 on the first crossbar 21 near the bottom frame 30; a first stud 23 is welded into the first through hole 22; the bottom frame 30 has a plurality of second through holes on the second crossbar 22 near the middle frame 20; a second stud 33 is welded into the second through hole; when the middle frame 20 and the bottom frame 30 are connected, each first stud 23 is aligned with a second stud 33, and the first stud 23 and the second stud 33 are fastened by bolts.

[0068] The bottom section to the middle section and the middle section to the upper section are all connected by bolts. The connection between the middle section frame 20 and the upper section frame 10 is provided with a first connecting plate 13 and a second connecting plate 24, respectively. The plates have holes. After aligning the holes of the first connecting plate 13 and the second connecting plate 24, bolts are inserted for fixing.

[0069] In the more severe stress conditions of the bottom-to-middle section connection, a stronger connection method is necessary. Bolts are directly inserted into the tubular beams of the bottom frame 30 and the middle frame 20. The crossbars at the top of the bottom frame 30 and the middle frame 20 are welded beams with multiple through holes. Welded studs are welded into these beams, and then the connection is made with bolts. Compared to directly welding connecting plates and using bolts for fastening, this method uses bolt sleeves welded into the frame beams for fastening, resulting in better stress resistance and better ability to cope with harsh stress conditions.

[0070] In some embodiments, since the bottom frame 30 and the middle frame 20 in this application are universal for all types of battery boxes, the bottom frame 30 and the middle frame 20 can also be welded together and assembled and stored as a whole without secondary assembly, thereby improving the connection strength without affecting the universality of the battery box.

[0071] Additionally, in some optional embodiments, the bottom frame 30 is provided with a connector 34; the bottom frame 30 also includes an integrated connector mounting plate 35 or a non-integrated connector mounting plate 36; the integrated connector mounting plate 35 is used to connect with the integrated connector 70, and the non-integrated connector mounting plate 36 is used to connect with the non-integrated connector 80; the integrated connector mounting plate 35 is detachably mounted on the bottom frame 30 via the connector 34, or the non-integrated connector mounting plate 36 is detachably mounted on the bottom frame 30 via the connector 34.

[0072] Currently, the mainstream connector types are integrated connectors 70 and non-integrated connectors 80. The main installation method is to design and manufacture corresponding battery boxes separately, and replace the boxes to install the two types of connectors. In this embodiment, a connector 34 is provided on the bottom frame 30 for detachably installing the integrated connector movable mounting plate 35 and the non-integrated connector movable mounting plate 36. Through modularization, it is compatible with both integrated and non-integrated electrical connectors. There is no need to replace the bottom frame 30; only the corresponding connector plate needs to be replaced to meet the installation requirements of both types of connectors.

[0073] Additionally, in some alternative embodiments, when the bottom frame 30 is fitted with the integrated connector mounting plate, the target accessory 40 is mounted on the bottom frame 30.

[0074] In the battery enclosure equipped with the integrated connector 70, the target components, including the water-cooling unit and battery management module, originally mounted on the upper frame 10, can be disassembled into several smaller parts and distributed across the lower frame 30. This allows the upper frame 10 to further reduce its overall height, serving only as the overall lifting and grabbing function and part of the battery pack 50 installation function, while transferring the accessory installation function to the lower frame 30. This further reduces the size of the upper frame 10, minimizing the space required for stocking different models of the upper frame 10.

[0075] Additionally, in some alternative embodiments, target accessory 40 includes at least one of a battery management module and a cooling component.

[0076] The battery management module can be a circuit board or an electrical control box, while the cooling component can be a water-cooled unit for cooling the battery pack. Corresponding functional components can be added based on the actual usage of the battery swapping enclosure.

[0077] Additionally, in some alternative embodiments, a housing 60 is also included; the housing 60 encloses the upper frame 10 except for the hoisting section, the bottom frame 30, and the middle frame 20.

[0078] like Figure 11As shown, the assembled battery box is covered with a skin. The skins of the bottom frame 30 and part of the middle frame 20 of different models of battery boxes can be interchanged. The upper frame 10 cannot be completely interchanged due to different heights, but the structural form is the same.

[0079] This application proposes a segmented battery swapping enclosure, including a bottom frame 30, a middle frame 20, and an upper frame 10. The bottom frame 30 and middle frame 20 are interchangeable in different battery enclosure models, and only the dimensions of the upper frame 10 need to be changed for battery enclosures with different capacities. When meeting a 280 kWh capacity requirement, the upper frame 10 is only used for hoisting and installing accessories, and does not house the standard PACK battery pack 50. When meeting a 350 kWh capacity requirement, two standard PACK battery packs 50 can be installed in the upper frame 10, and other kWh installation components such as water-cooled units are installed inside the dedicated 350 kWh upper section. In this way, only the corresponding upper module needs to be replaced to meet the requirements of battery enclosures with different capacities, without needing to replace the bottom frame 30 and middle frame 20. Manufacturers do not need to stock the entire battery enclosure; the bottom frame 30 and middle frame 20 of different battery enclosure models can share inventory, and only the corresponding upper frame 10 needs to be stocked separately. This reduces inventory pressure on enterprises and facilitates standardized production.

[0080] Secondly, this application provides a battery box, including any of the segmented battery swapping boxes described above; a target accessory 40 is installed in the accessory mounting section of the upper frame 10; a battery assembly is installed in the middle frame 20; the battery assembly is electrically connected to at least a portion of the target accessory 40; a battery interface is installed in the bottom frame 30; and the battery interface assembly is electrically connected to the battery assembly.

[0081] Additionally, in some optional embodiments, the upper frame 10 may also include a battery mounting section for removably mounting the battery pack 50; wherein, when the battery pack 50 is installed in the battery mounting section, the battery pack 50 is electrically connected to the battery interface, and the battery power of the housing meets a first power requirement; when the battery pack 50 is not installed, the battery power of the housing meets a second power requirement.

[0082] Thirdly, this application discloses a vehicle including any of the battery boxes described in the second aspect.

[0083] The battery box and vehicle provided in this embodiment include the segmented battery swapping box of any of the above embodiments, and therefore have the same beneficial effects, which will not be repeated here.

[0084] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0085] Although alternative embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the alternative embodiments as well as all changes and modifications falling within the scope of the present invention.

[0086] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or terminal device that includes that element.

[0087] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model.
