Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery pack with a support frame and a mining truck battery box. Background Technology

[0002] Currently, most pure electric mining trucks used in mining scenarios rely on rechargeable battery systems. Due to the inherent demands of mining trucks, their overall power requirements are high, and recharging takes a long time, making them unsuitable for heavy-load applications. Heavy-duty truck battery swapping technology has been developed and is already in mass production, indicating its maturity. However, heavy-duty truck batteries are relatively small and their capacity is incompatible with the truck frames, preventing direct application in mining trucks. Furthermore, mining truck battery boxes require numerous battery packs. Current technologies primarily employ side-pushing assembly, where multiple insertion slots are formed on the side of the battery frame. The battery packs are hoisted to the side of the battery frame using lifting equipment, and then manually or with specialized equipment, they are pushed into the slots to move into the battery frame. This assembly process, with its added side-pushing step, increases both cost and assembly difficulty. Utility Model Content

[0028] Optionally, the battery frame includes longitudinal beams;

[0029] The adapter includes a motherboard, the edge of which is bent to form a first bending plate;

[0030] The first bent plate is connected to the longitudinal beam by fasteners, and the main plate is connected to the fixing hole on the fixing seat by fasteners.

[0031] Optionally, the edge of the motherboard is bent to form a second bent plate;

[0057] Example 1

[0058] like Figures 1 to 7 As shown in the illustration, this application provides a detailed description of the battery pack 2 of the battery box. The battery pack 2 includes a support frame 22, a battery pack body 21, and fixing seats 23. The battery pack body 21 is located on one side of the support frame 22 along its thickness direction and is fixed to the support frame 22 by fasteners. Each fixing seat 23 is located on the edge of the support frame 22 and is fixed to the support frame 22. Each fixing seat 23 has a fixing hole 2322. When the battery pack 2 of this application is assembled into the battery frame 1 of the battery box, the battery pack 2 can be hoisted into the battery frame 1 from top to bottom using a battery swapping device, and then the support frame 22 can be fixed to the battery frame 1 using an adapter 3 and fasteners. The fixing holes 2322 on the fixing seats 23 are used to fix them to the adapter 3 or directly to the battery frame 1 using fasteners, which significantly improves assembly efficiency.

[0059] The battery pack 2 of this application has a built-in support frame 22, which can be directly fixed to the battery frame 1 of the battery box. There is no need to set a horizontal support frame 22 on the battery frame 1. It supports each battery pack 2 to be hoisted into the battery frame 1 from top to bottom and fixed to the battery frame 1 with fasteners. This simplifies the internal structure of the battery frame 1, facilitates the assembly of the battery pack 2, and improves the assembly efficiency of the entire battery box.

[0060] In some possible implementations, the support frame 22 includes multiple beams arranged in a crisscross pattern, with fixed mounting seats 23 disposed on the beams. At least a portion of the beams are connected to the battery pack body 21 by fasteners. The battery pack 2 and the battery frame 1 are directly connected and fixed by fasteners, which can be bolts. The battery pack body and the support frame are detachable, facilitating separate production and transportation of individual structural components.

[0061] In some possible implementations, such as Figure 5 As shown, two flat strips 221a are sequentially arranged along the thickness direction of the support frame 22 on the beam body, and a cavity is formed between the two flat strips 221a. A small hole 221b is opened on one flat strip 221a, and a large hole 221c is opened on the other flat strip 221a. One end of the fastener passes through the large hole 221c and the small hole 221b in sequence and is connected to the battery pack body 21. The other end of the fastener is located in the cavity and is confined to the flat strip 221a with the small hole 221b.

[0062] The fastener can be a bolt, including a stud and a cap at the end of the stud. The stud passes through the large hole 221c and the small hole 221b in sequence and is connected to the battery pack body 21. The cap is located inside the cavity and does not protrude from the lower edge of the support frame 22, so as not to interfere with the setting of other structural components inside the battery box.

[0063] In some possible implementations, a fixed mating seat 23 is provided at each of the four corners of the support frame 22, so that the four corners of the support frame 22 can be stably assembled onto the battery frame 1, thereby improving the assembly structure strength and assembly structure stability of the support frame 22.

[0064] In some possible implementations, the support frame 22 includes a frame 221, which is generally U-shaped and encloses an inner space. A beam is disposed within this inner space and connected to the frame 221. A fixing seat 23 is located on the same plane as the frame 221, situated outside the frame 221 and connected to it. The fixing seat 23's location along the edge of the frame 221 facilitates connection and assembly with the battery frame 1.

[0065] In some possible implementations, such as Figure 2 and Figure 3As shown, the frame 221 includes four beams that enclose the inner space. Adjacent beams are vertically connected, with a gap between the ends of one beam and the other to form an outer accommodating space 222. This outer accommodating space is isolated from the inner space. The fixing seat 23 is located in the outer accommodating space 222 and connected to the frame 221. The fixing seat 23 can be located at a corner of the outer accommodating space 222. The fixing seat 23 can be welded to two adjacent beams and does not protrude from the outer accommodating space 222, thus avoiding interference with the battery frame 1 during assembly.

[0066] In some possible implementations, the fixed mounting base 23 includes a central plate 231 and side plates 232 located on both sides of the central plate 231. One of the side plates 232 is attached to the edge of the frame 221, and the other side plate 232 is provided with the fixing hole 2322.

[0067] In this embodiment, the cross-section of the fixed mating seat 23 is approximately U-shaped. One of its two parallel side plates 232 is attached to a beam of the frame 221, while the other is provided with a fixing hole 2322 to facilitate connection and fixation with the support frame.

[0068] In some possible implementations, such as Figure 3 As shown, the fixed mating seat 23 includes a nut 2321, which is located between the two side plates 232 and connected to the side plate 42 having the fixing hole 2322. The threaded groove of the nut 2321 communicates with the fixing hole 2322. The nut 2321 has an internal thread, which facilitates threaded connection and assembly with fasteners such as bolts.

[0069] Example 2

[0070] like Figures 1 to 7 As shown, this embodiment provides a battery box, which includes a battery frame 1, a battery pack, and an adapter 3. The battery frame encloses a battery cavity (which can be the inner cavity mentioned above). The adapter 3 is detachably connected to the battery frame 1. The battery pack 2 mentioned above is located inside the battery cavity and supported by the adapter 3. The adapter 3 is connected to the fixing hole 2322 on the fixing seat 23 by fasteners. The battery pack 2 is transferred to the battery frame 1 through the adapter 3. Each adapter 3 is installed on the battery frame of the battery box on-site during the hoisting of the battery pack 2.

[0071] During the assembly of battery pack 2, the adapter 3 is first pre-installed on the battery frame 1 using bolts. The bolts are not tightened initially. Then, battery pack 2 is moved downwards until the mounting hole on the fixing seat 23 aligns with the fixing hole 2322 on the adapter 3. At this point, the bolts are threaded through the through hole on the adapter 3 and connected to the fixing hole 2322 on the fixing seat 23, again without tightening the bolts. During this process, the battery swapping equipment maintains the lifting of battery pack 2 to reduce pressure on the adapter. Finally, all bolts are tightened sequentially to securely fix battery pack 2 to the battery frame 1. The battery swapping equipment can then be removed to proceed with the assembly of other battery packs 2. The battery swapping equipment is a lifting mechanism.

[0072] In some possible implementations, the battery frame includes longitudinal beams 13, which are connected by transverse beams to form an integral battery frame structure. For example... Figure 6 and Figure 7 As shown, the adapter 3 includes a main board 31, the edges of which are bent to form a first bent plate 32 and a second bent plate 33. The first bent plate 32 is connected to the longitudinal beam 13 by fasteners, and the main board 31 is connected to the fixing hole 2322 on the fixing seat 23 by fasteners. The second bent plate 33 is supported on the bottom of the fixing seat 23. The adapter 3 can stably support the battery pack 2 and fix the battery pack 2 by fasteners, thus improving the assembly structure stability of the battery pack 2.

[0073] The mining truck battery box provided in this application is relatively large, especially in length, and has a large capacity, making it suitable for installation on mining trucks. The mining truck is equipped with a battery base. The battery box and battery base of this application are detachable and can be used together. When the battery box is placed on the battery base, a locking mechanism on the battery base can lock or unlock the battery box, facilitating quick battery box replacement and achieving rapid power replenishment.

[0074] Example 3

[0075] like Figures 1 to 14 As shown in the illustration, this application provides a more detailed description of the battery box, which includes: a battery frame 1 and multiple battery packs 2. The battery frame 1 has a lifting fitting 111 at its top. Each of the battery packs 2 is disposed within the battery frame 1, and the battery packs 2 form multiple rows within the battery frame 1, with each row of battery packs 2 arranged sequentially along the height direction of the battery frame 1. Figure 12 and Figure 13 As shown, in the top row of battery packs 2, a clearance space 10 is formed between some adjacent battery packs 2. The lifting assembly 111 is exposed within this clearance space 10. The lifting assembly 111 is designed to be gripped and transferred by the grabber (or hook) of the battery swapping equipment when the battery box is replaced in the vehicle.

[0076] The large-size battery box provided in this application has multiple rows and columns of battery packs 2 arranged on it. The top row of battery packs 2 has an empty battery position reserved at the position of the lifting assembly 111, forming a clearance space 10. This clearance space avoids the lifting assembly 111, allowing the grabber of the battery swapping equipment to move to the clearance space 10 and smoothly grab (e.g., attach) the battery pack to the lifting assembly 111 for transport. The layout of each module inside the battery box in this application significantly improves the overall space utilization and maximizes the control of the height of the battery box.

[0077] In other words, each of the battery packs 2 forms multiple rows of battery packs 2, and the rows of battery packs 2 are arranged sequentially along the length of the battery frame 1. The bottom battery packs 2 in each row are located on the same horizontal plane, and the number of battery packs 2 in some rows is less than the number of battery packs 2 in the two adjacent rows on either side, so as to form the clearance space 10 on top of each battery pack 2. In this embodiment, by reducing the number of battery packs 2 in a certain row, the top of that row of battery packs 2 is lower than the two adjacent rows on either side, thus forming the clearance space 10 on top of that row of battery packs 2.

[0078] In some possible implementations, the top of the battery frame 1 of the battery box can be slightly higher than the top row of battery packs 2, which maximizes the control of the size of the battery frame 1 and avoids affecting the arrangement of other structural components on the mining card.

[0079] In some possible implementations, the large-size battery box includes an outer panel 4 connected to the battery frame 1. The outer panel 4 encloses a lifting guide cavity 430 and an inner cavity. The lifting guide cavity 430 is at least partially located in the clearance space 10. The lifting guide cavity 430 is exposed to the outer panel 4, meaning its opening is visible on the surface of the outer panel 4. A lifting mating part 111 is exposed to the lifting guide cavity 430, meaning it is clearly visible within the field of view of the lifting guide cavity 430. The lifting mating part 111 may be located inside the lifting guide cavity 430 or along its edge, forming part of the boundary surface of the lifting guide cavity 430. Alternatively, although the lifting mating part 111 is spaced from the lifting guide cavity 430, there is no direct obstruction between them. Each battery pack 2 is located in the inner cavity, and the lifting guide cavity 430 is isolated from the cavity.

[0080] In this implementation scheme, the outer plate 4 can be a skin covering the battery frame 1, serving to enclose the battery frame 1 and protect the internal battery pack 2. The outer plate 4 isolates the battery pack 2 from the lifting mating part 111, ensuring that the grabber of the battery swapping equipment will not contact the individual battery packs 2 inside the battery box when grabbing the lifting mating part 111, thus improving safety. Furthermore, the lifting guide cavity guides the grabber, facilitating its smooth attachment to the lifting mating part 111.

[0081] In some possible implementation schemes, combined Figure 8 and Figure 9 As shown, the outer plate 4 has a flat plate portion and a recessed isolation plate frame 43. The flat plate portion fits against the outer side of the battery frame 1 to form a flat outer surface of the battery box. The isolation plate frame 43 is connected to the flat plate portion and is recessed into the clearance space 10. The isolation plate frame 43 encloses and forms the lifting guide cavity 430. The lifting guide cavity 430 is generally an L-shaped guide channel. The lifting mating part 111 can be located on the inner wall of the guide channel or constitute a part of the inner wall of the guide channel. The guide channel can guide the gripper to slide in and attach to the lifting mating part 111. The lifting mating part 111 is located at the top of the bending transition area of ​​the L-shaped guide channel.

[0082] In some possible implementations, the flat plate portion includes a top plate 41 and a side plate 42, and the partition frame 43 includes a lower recessed shell portion 431 disposed on the top plate 41 and a side recessed shell portion 432 disposed on the side plate 42. When the top plate 41 is connected to the top of the frame and the side plate 42 is connected to the side of the frame, the lower recessed shell portion 431 and the side recessed shell portion 432 are spliced ​​together to form the partition frame 43.

[0083] In this embodiment, the lower concave shell 431 is pre-fixed to the top plate 41, and the side concave shell 432 is pre-fixed to the side plate 42. During the assembly of the battery pack 2, the side plate 42 is assembled to the side of the battery frame 1 in sequence, and the top plate 41 is assembled to the top of the battery frame 1, so that the lower concave shell 431 and the side concave shell 432 are connected to form a lifting guide cavity 430. The lifting mating part 111 is exposed (e.g., located in) the lifting guide cavity 430. When the gripper enters the guide cavity, the gripping hook can be rotated and limited to the bottom of the lifting mating part 111. When the gripper is lifted upward, it can be hooked to the bottom of the lifting mating part 111. The isolation plate frame 43 forms openings in the top and side of the battery box that connect to the hoisting guide cavity 430. The gripper can extend into the hoisting guide cavity 430 through the top opening. When the gripper grabs the hoisting mating part 111, the gripper can extend partially through the side opening, that is, the side opening is used to avoid the gripper.

[0084] In some possible implementations, the battery frame 1 has a top beam 11, the cross-section of which can be rectangular or square. A top plate 41 and side plates 42 are respectively attached to two perpendicular surfaces of the top beam 11, which passes through or is close to the lifting guide cavity 430. A lifting mating part 111 is located in the lifting guide cavity 430 and connected to the top beam 11.

[0085] The hoisting fitting part 111 can be a metal plate or other wear-resistant high-strength plate. The hoisting fitting part 111 can be welded or fixed to the top beam 11 by fasteners.

[0086] In some possible implementations, such as Figure 9 As shown, the side concave shell portion 432 includes two side concave blocks 4321 and a bottom concave block 4322. The bottom concave block 4322 is lower than the top beam 11. The two side concave blocks 4321 are respectively disposed on both sides of the bottom concave block 4322. The side concave blocks 4321 are located between the bottom concave block 4322 and the top beam 11. The hoisting fitting portion 111 is disposed at the bottom of the top beam and located between the two side concave blocks 4321. The shell wall of the lower concave shell portion 431 is respectively connected to the side concave blocks 4321 and the bottom concave block 4322. The shell wall of the lower concave shell portion 431 can overlap the side concave blocks 4321 and the bottom concave block 4322 and be welded and fixed to the side concave blocks 4321 and the bottom concave block 4322.

[0087] In some possible implementations, such as Figure 12 and Figure 13 As shown, the top row of battery packs 2 forms clearance spaces 10 on both sides of the battery frame 1 along its length. The battery frame 1 has two top beams 11, which pass through the two clearance spaces 10 respectively. Each top beam 11 is provided with a lifting engagement part 111 at each clearance space to form a total of four lifting engagement parts 111, which facilitates the gripping of four parts by the grabber to smoothly transfer the battery pack.

[0088] In some possible implementations, such as Figure 12 and Figure 13 As shown, the large-size battery box includes a water-cooling unit 6 and a water tank 5. The water tank 5 is at least partially located in the clearance space 10. The water-cooling unit 6 is connected to water-cooling pipes, which are connected to each of the battery packs 2. The water-cooling pipes are connected to the water tank 5, which is located at the highest point of the water-cooling pipes and can be used to add condensate.

[0089] In this implementation scheme, by placing the water bottle 5 within the clearance space 10, the internal space of the battery frame 1 is fully utilized. There is no need to specifically reserve space for the water bottle 5 in other locations on the battery frame 1. The water bottle 5 is entirely located within the clearance space 10 and does not protrude from it; it can be enclosed within the cavity by the flat top and side panels 42. For example... Figure 13 As shown, the clearance space 10 extends along the thickness direction of the battery frame 1, and the two top beams 11 on the battery frame 1 are located at both ends of the clearance space 10 along the thickness direction of the battery frame 1. That is, hoisting mating parts 111 are respectively provided at both ends of the clearance space 10 along the length direction (thickness direction of the battery frame 1). The water bottle 5 is located in the middle of the clearance space 10, between the two hoisting mating parts 111.

[0090] In some possible implementations, the large battery box includes a kettle mounting bracket 7, which is at least partially located within the clearance space 10 and connected to the battery frame 1. The battery frame 1 has lifting fittings 111 on both sides of the kettle mounting bracket 7, and the kettle 5 is mounted on the kettle mounting bracket 7. The kettle mounting bracket 7 facilitates the installation and arrangement of the kettle 5.

[0091] like Figure 12 and Figure 14 As shown, the bottom of the battery frame 1 is provided with a locking engagement part 12. When the battery box is placed on the battery base on the mining truck, the locking mechanism on the battery base can press against the locking engagement part 12 to fix the battery box. The bottom of the battery frame 1 is provided with a bottom beam, and the locking engagement part 12 can be a gasket set on the bottom beam. The gasket has high structural strength, good wear resistance, and is detachable, making it convenient to cooperate with the locking mechanism.

[0092] like Figure 12 As shown, the battery box also includes an electrical connector 9 and a high-voltage box 8. The electrical connector 9 is located at the bottom center of the battery frame 1, and the high-voltage box 8 is located between the electrical connector 9 and each battery pack 2. For example, the high-voltage box 8 can be located on top of the electrical connector 9.

[0093] In some possible implementations, such as Figure 12 and Figure 14 As shown, the battery box provided in this embodiment can be composed of 16 standard battery packs 2, forming an 800 kWh battery swapping box. Eight locking parts 12 are provided at the bottom of the battery box to lock into the battery base, ensuring high reliability of the locking mechanism. The high-voltage box 8 is located on top of and adjacent to the electrical connector 9, facilitating wiring harness arrangement and improving the space utilization of the battery box. Two water-cooled units 6 can be installed on both sides of the bottom of the high-voltage box 8, meaning two high-power water-cooled units are located on opposite sides of the bottom of the battery box.

[0094] The battery box contains 16 standard battery packs arranged in three layers, with six packs per layer.
