Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery base and battery system. Background Technology

[0002] The battery trays provided in the existing technology are mostly quick-change structures, that is, electric cylinders or pneumatic cylinders are set on the bottom of the battery tray. The electric cylinders or pneumatic cylinders are used as power sources to drive the locking components to quickly open and close, lock or unlock the battery box to ensure the efficient operation of battery swapping.

[0003] In related technologies, a mobile energy product is provided that does not require frequent battery swapping. The product is transported to a target location to provide the power needed for production or daily life. Although the quick-swap battery trays provided in the prior art can meet this requirement in application, the cost is relatively high. In this mobile energy product, the battery box is integrated as an energy unit onto the tray and installed as a whole on a vehicle or placed on the ground. The connection and locking relationship between the battery box and the tray does not require quick swapping. If the quick-swap structure provided in the prior art is used, the overall cost will be high, affecting the product's competitiveness.

[0004] Therefore, there is an urgent need for a low-cost locking mechanism that does not require drive components, such as electric or pneumatic cylinders, but can reliably and effectively lock the battery box for a long time without easily coming loose. Utility Model Content

[0055] Example 1

[0056] This application provides a battery tray 100, which includes a tray body 1, a latch 22, and a plurality of guides 21. The guides 21 are vertically connected to the tray body 1, and each guide 21 has a cavity and a locking opening 211 communicating with the cavity. The latch 22 is at least partially located in the cavity. One end of the latch 22 is rotatably connected to the tray body 1 or the guides 21, and the other end of the latch 22 is provided with a locking portion 221. The locking portion 221 has a locking hole 2211. Under external force, the latch 22 can rotate, causing the locking portion 221 to extend out of the locking opening 211, and the locking hole 2211 to be exposed to the outside of the guides 21.

[0057] In some possible implementations, the battery base 100 includes a pin 23 that, when the locking part 221 extends out of the locking opening 211, can pass through the locking hole 2211 and be confined to the outside of the guide body 21 to prevent the locking part 221 from retracting into the cavity.

[0058] When the battery box 200 is placed on the battery base 100 of this application, the worker can rotate the locking tongue 22 by hand or with the aid of tools, so that the locking part 221 of the locking tongue 22 extends out of the locking port 211 of the guide body 21. Then, the pin 23 is inserted into the locking port 211, and the pin 23 is limited to the outside of the guide body 21, restricting the position of the locking part 221, so that the locking part 221 remains in the locked position and will not disengage. The battery base 100 provided by this application is suitable for scenarios where the battery box 200 is fixed for a long time and there is no need for frequent disassembly and assembly of the battery box 200. The locking structure of the battery base 100 of this application is simple and reliable, reducing costs. Through the cooperation of the locking tongue 22 and the pin 23, this application realizes the integration of the battery base 100 and the battery box 200 into one unit, meeting the usage needs of mobile energy scenarios.

[0059] In some possible implementations, the pin 23 and the locking hole 2211 can be interference-fitted, and the pin 23 can be hammered into the locking hole 2211 with the help of a tool, so that the pin 23 is fixed to the locking part 221 and will not easily come off the locking part 221.

[0060] In some possible implementations, the pin 23 passes through the locking hole 2211, and the pin 23 is tightly fitted to the outer wall of the guide body 21. There is significant pressure and friction between the pin 23 and the guide body 21, ensuring that their relative positions remain unchanged and the pin 23 does not easily disengage. Only under sufficiently large external force can the pin 23 slide out of the locking hole 2211.

[0061] In some possible implementation schemes, combined Figure 13 As shown, the guide body 21 has an operating port 212, which communicates with the cavity. The operating port 212 is located on one or both sides of the guide body 21 in a direction perpendicular to the swing plane of the latch 22. The operating port 212 allows the operator to insert their hand or a tool through the operating port 212 into the cavity to act on the latch 22, keeping the locking hole 2211 outside the guide body 21. The operator also needs to use a tool to press and fix the latch 22 to facilitate the insertion and fixing of the pin 23 into the locking hole 2211.

[0062] In some possible implementations, the guide body 21 includes a guide main shell and a cover plate 213, the guide main shell being fixed to the base body 1. The guide main shell has the operating port 212, the cavity, and the locking port 211, and the cover plate 213 is detachably connected to the guide main shell, the cover plate being used to cover or open the operating port 212.

[0063] In this implementation scheme, the locking port 211 can be sealed by the cover plate to prevent external impurities from entering the interior, thereby protecting the internal structure of the guide shell.

[0064] In some possible implementations, the cover plate is provided with an observation port 2131. The observation port 2131 is small in size and can be an elongated hole parallel to the base body 1, which facilitates external viewing of the interior of the cavity and allows tools to be inserted into the cavity through the observation port 2131 to operate the locking tongue 22. The elongated hole extends in the same direction as the locking part 221 when locked, which facilitates the movement of the operating part along the elongated hole to push the locking tongue 22 to swing.

[0065] In some possible implementations, the locking tongue 22 includes a swing body 222, with a locking part 221 disposed at one end of the swing body 222. The other end of the swing body 222 is hinged to the base body 1. An operation engagement hole 2212 is provided on the locking part 221. The operation engagement hole 2212 is located on the side of the locking hole 2211 near the swing body 222. When the locking part 221 extends out of the locking port 211, the operation engagement hole 2212 is located in the cavity and is close to the operation port 212.

[0066] A tool can be inserted through the end of the operating port 212 into the operating mating hole 2212, and the locking tongue 22 can be pushed towards the locking port 211 while continuously applying force. This keeps the locking hole 2211 of the locking part 221 on the locking tongue 22 outside the guide body 21. At this time, the pin 23 can be inserted into the locking hole 2211. The tool holds the locking tongue 22 in place to prevent it from swinging back during the installation of the pin 23, which facilitates the assembly of the pin 23.

[0067] In some possible implementations, the base body 1 includes a lower frame 12, an upper frame 11, and a column 13 connecting the upper frame 11 and the lower frame 12. The lower frame 12 is a straight frame that can be easily supported directly on the ground or on the chassis of a vehicle, meeting the usage requirements of mobile energy scenarios. The guide body 21 is disposed on the upper frame 11.

[0068] This application also provides a battery system, including a battery case 200 and the aforementioned battery base 100. The battery case 200 is supported on the base body 1 of the battery base 100. The guide body 21 and the battery case 200 are mutually restrictive. The locking part 221 is engaged with the battery case 200. A pin 23 passes through a locking hole 2211 on the locking part 221. The pin 23 is limited to the outside of the guide body 21, so that the locking part 221 keeps the battery case 200 locked and prevents the locking part 221 from retracting into the cavity, so that the locking part 221 can reliably and effectively lock the battery case 200 located on the battery base 100. This achieves the integration of the battery base 100 and the battery case 200 into one unit.

[0069] The battery system of this application does not require frequent battery swapping. The product can be transported to the target location by vehicle and unloaded on the ground or other platforms to provide the electrical energy needed for production or daily life.

[0070] In some possible implementations, the battery system includes at least two battery boxes 200, each of which is mounted on the battery base 100. By adding at least two battery boxes 200 to the battery base 100, the capacity of the battery system is increased to meet the customer's demand for high capacity.

[0071] Example 2

[0072] like Figures 1 to 13 As shown in the illustration, this application provides a detailed description of a battery base 100, which includes: a base body 1, a locking tongue 22, a pin 23, a limiting block 24, and multiple guide bodies 21. The guide bodies 21 are vertically connected to the base body 1. Each guide body 21 has a cavity and a locking opening 211 communicating with the cavity. The locking tongue 22 is at least partially located in the cavity. One end of the locking tongue 22 is rotatably connected to the base body 1 or the guide body 21, and the other end of the locking tongue 22 is provided with a locking portion 221. The locking portion 221 has a locking hole 2211. Under external force, the locking tongue 22 can rotate, causing the locking portion 221 to extend out of the locking opening 211. The pin 23 can pass through the locking hole 2211. The limiting block 24 is detachably connected to the guide body 21, and the limiting block 24 and the pin 23 are mutually limiting and engaging to fix the locking portion 221.

[0073] When the battery box 200 is placed on the battery base 100 of this application, the worker can rotate the locking tongue 22 by hand or with the aid of tools, so that the locking part 221 of the locking tongue 22 extends out of the locking port 211 of the guide body 21. Then, the pin 23 is inserted into the locking port 211, and the pin 23 is limited to the outside of the guide body 21, restricting the position of the locking part 221, so that the locking part 221 remains in the locked position and will not disengage. The limiting block is installed on the guide body 21 to prevent the pin 23 from disengaging. The battery base 100 provided by this application is suitable for scenarios where the battery box 200 is fixed for a long time and there is no need for frequent disassembly and assembly of the battery box 200. The locking structure of the battery base 100 of this application is simple and reliable, reducing costs. Through the cooperation of the locking tongue 22, the pin 23 and the limiting block 24, this application realizes the integration of the battery base 100 and the battery box 200 into one unit, meeting the usage needs of mobile energy scenarios.

[0074] In some possible implementations, such as Figure 5 and Figure 13As shown, there is a gap between the pin 23 and the outer wall of the guide body 21. The limiting block 24 has a main block 241 and a fastening arm 242 connecting the main block 241. The fastening arm 242 is inserted between the pin 23 and the guide body 21. The fastening arm 242 is tightly fitted to the outer wall of the guide body and the pin 23 respectively. The main block 241 is detachably connected to the guide body 21.

[0075] The thickness of the clamping arm 242 is slightly larger than the gap between the outer walls of the pin 23 and the guide body 21. Using a tool applied to the limiting block 24, the clamping arm 242 is hammered between the pin 23 and the guide body 21. The clamping arm 242 makes tight contact (e.g., interference fit) with both the pin 23 and the guide body 21, locking the locking part 221 securely. The locking part 221 will not wobble. The battery base 100 and the battery box 200 maintain a reliable and stable locking relationship, ensuring the battery box 200 is fixed in position and does not wobble, thus improving the stability of the assembly structure of the battery base 100 and the battery box 200.

[0076] In some possible implementations, such as Figure 5 As shown, a wedge-shaped portion 2421 is provided at the end of the clamping arm 242 facing away from the main block 241. The thickness of the wedge-shaped portion 2421 gradually decreases in the direction from the main block 241 to the clamping arm 242. Under external force, the wedge-shaped portion 2421 can pass between the pin 23 and the guide body 21, causing the clamping arm 242 to press against the guide body 21 and the pin 23. By setting one end of the clamping arm 242 into a wedge-shaped structure with a tapered tip that is wider at the top and narrower at the bottom, the contact area is small, allowing for concentrated force application. This enables the wedge-shaped portion 2421 to quickly embed into the gap between the outer wall of the pin 23 and the guide body 21. This design reduces initial resistance, facilitates rapid insertion of the clamping arm 242, and improves assembly efficiency.

[0077] In some possible implementations, the limiting block 24 further includes a shielding arm 243 connected to the main block 241. A receiving cavity is formed between the shielding arm 243 and the fitting arm 242, and the pin 23 is accommodated within this cavity. The shielding arm 243 serves to protect the limiting pin 23. The opening of the cavity formed between the shielding arm 243 and the fitting arm 242 faces downwards to prevent rainwater from entering the receiving cavity and contacting the pin 23. The cavity formed between the shielding arm 243 and the fitting arm 242 also provides stable accommodation of the pin 23, preventing easy displacement of the pin 23, thus protecting the pin 23 and extending its service life.

[0078] In some possible implementation schemes, combined Figure 13As shown, the limiting block 24 also includes an end plate 244, which is connected to the fastening arm 242 and the blocking arm 243. The end plate 244 is located at one end of the receiving cavity and restricts the movement of the pin 23 along its length, preventing the pin 23 from disengaging from the locking hole 2211 and improving the reliability and safety of the product. Two limiting blocks 24 can be provided on each guide body 21. The two limiting blocks 24 are respectively located on both sides of the locking port 211 and respectively limit the movement of the pin 23 on both sides. The end plates 244 on the two limiting blocks 24 are respectively located at both ends of the pin 23 along its length, preventing the pin 23 from disengaging from the locking hole 2211.

[0079] In some possible implementations, such as Figure 6 As shown, a through hole 2411 is provided on the main block 241. One end of the fastener 25 passes through the through hole 2411 and is connected to the guide body 21, while the other end of the fastener 25 is confined within the main block 241. The main block 241 is located at the top of the pin 23. The fastener 25 can be a bolt, with the stud of the bolt threaded onto the guide body 21 through the through hole 2411.

[0080] A recessed groove can be provided on the main block 241, and the through hole 2411 is formed in the bottom wall of the recessed groove. The cap of the fastener 25 is accommodated in the recessed groove. The cap is embedded in the recessed groove and does not protrude significantly from the main block 241, so as to avoid collision and interference with external structures.

[0081] In some possible implementations, such as Figure 6 As shown, the locking tongue 22 includes a swing body 222 and a stop block 223. The locking part 221 is disposed at one end of the swing body 222, and the other end of the swing body 222 is hinged to the base body 1. The stop block 223 is connected to the swing body 222 and is located between the rotation axis of the locking part 221 and the swing body 222. An auxiliary locking port 214 is provided on the guide body 21. The auxiliary locking port 214 communicates with the cavity. When the locking part 221 extends out of the locking hole 2211, the stop block extends out of the auxiliary locking port 214 to abut against the battery box 200.

[0082] When the battery box 200 is supported on the battery base 100, when the locking tongue 22 swings to the point where the locking part 221 extends out of the locking port 211 on the guide body 21, the abutment block 223 also extends out of the auxiliary locking port 214 on the guide body 21 and abuts against the inner wall of the bottom frame of the battery box 200. Multiple guide bodies 21 on the battery base 100 are arranged sequentially along the circumference of the bottom frame of the battery box 200. The abutment blocks 223 on each guide body 21 apply an outward force to different positions on the bottom frame, thus fixing the battery box 200 and preventing the battery box 200 from easily wobbling due to gaps between it and the guide bodies 21. The locking part 221 and the abutment block 223 work together to secure the battery box 200, improving the assembly structure stability of the battery box 200.

[0083] This application provides a battery system including: a battery base 100 and a battery box 200 as described above. The battery box 200 is supported on the base body 1 of the battery base 100. A guide 21 and the battery box 200 are mutually restrictive. A locking part 221 is engaged with the battery box 200. A pin 23 passes through a locking hole 2211 on the locking part 221. A limiting block 24 is connected to the guide 21, and the limiting block 24 and the pin 23 are mutually restrictive to fix the locking part 221, so that the locking part 221 remains in the locked position, effectively and reliably fixing the battery box 200, and integrating the battery base 100 and the battery box 200 into a single structure. In this application, the locking structure of the battery base 100 and the battery box 200 is simple, reliable, and low in cost, meeting the usage requirements of mobile energy scenarios. The battery system of this application can be transported to the target location by vehicle, and after unloading, it can provide discharge services at the target location, solving the problems of no mains power and difficult wiring outdoors.

[0084] This application also provides a method for locking a battery box, including:

[0085] Step S1: Set a locking hole 2211 on the locking part 221 of the locking tongue 22 of the battery base 100, swing the locking tongue 22 so that the locking part 221 extends out of the locking port 211 of the guide body 21 on the battery base 100 and is engaged with the battery box 200.

[0086] In this step, after the battery box 200 is hoisted to the battery base 100 by the hoisting equipment, the operator can apply external force to the locking tongue 22 by hand or with the help of tools, so that the locking tongue 22 swings until the locking part 221 of the locking tongue 22 extends out of the locking port 211 on the guide body 21, so that the locking hole 2211 of the locking part 221 on the locking tongue 22 remains outside the guide body 21.

[0087] Step S2: Insert the pin 23 into the locking hole 2211;

[0088] In one embodiment, the pin 23 and the locking hole 2211 can be interference-fitted, and the pin 23 can be hammered into the locking hole 2211 with the help of a tool, so that the pin 23 is fixed to the locking part 221 and will not easily come off the locking part 221.

[0089] In another embodiment, the pin 23 passes through the locking hole 2211, and the pin 23 and the outer wall of the guide 21 can fit tightly together. There is significant pressure and friction between the pin 23 and the guide 21, ensuring that their relative positions remain unchanged and the pin 23 will not easily disengage. Only under sufficiently large external force can the pin 23 slide out of the locking hole 2211.

[0090] The guide body 21 has an operating port 212 that communicates with the cavity. The operating port 212 is located on one or both sides of the guide body 21 in a direction perpendicular to the swing plane of the latch 22. The operating port 212 allows the operator to insert their hand or a tool through the operating port 212 into the cavity to act on the latch 22, keeping the locking hole 2211 outside the guide body 21. The operator also needs to use a tool to press and fix the latch 22 to facilitate the insertion and fixing of the pin 23 into the locking hole 2211.

[0091] like Figure 10 and Figure 13 As shown, the guide body 21 includes a guide main shell and a cover plate 213, with the guide main shell fixed to the base body 1. The guide main shell has the operating port 212, the cavity, and the locking port 211. The cover plate is detachably connected to the guide main shell and is used to cover or open the operating port 212. The cover plate can close the locking port 211 to prevent external impurities from entering the interior, thus protecting the internal structure of the guide main shell.

[0092] An observation port 2131 is provided on the cover plate 213. The observation port 2131 is small in size and can be an elongated hole parallel to the base body 1, which allows for easy external viewing of the interior of the cavity and facilitates the insertion of tools into the cavity through the observation port 2131 to operate the locking tongue 22. The extension direction of the elongated hole is the same as the extension direction of the locking part 221 when locked, which allows the operating part to move along the elongated hole and push the locking tongue 22 to swing.

[0093] The locking tongue 22 includes a swing body 222, the locking part 221 is disposed at one end of the swing body 222, and the other end of the swing body 222 is hinged to the base body 1, as shown below. Figure 5As shown, the locking part 221 is provided with an operation mating hole 2212. The operation mating hole 2212 is located on the side of the locking hole 2211 near the swing body 222. When the locking part 221 extends out of the locking port 211, the operation mating hole 2212 is located in the cavity and is close to the operation port 212.

[0094] A tool can be inserted through the end of the operating port 212 into the operating mating hole 2212, and the locking tongue 22 can be pushed towards the locking port 211 while continuously applying force. This keeps the locking hole 2211 of the locking part 221 on the locking tongue 22 outside the guide body 21. At this time, the pin 23 can be inserted into the locking hole 2211. The tool holds the locking tongue 22 in place to prevent it from swinging back during the installation of the pin 23, which facilitates the assembly of the pin 23.

[0095] Step S3: Insert the limiting block 24 between the pin 23 and the outer wall of the guide body 21, so that the limiting body is tightly fitted with the guide body 21 and the pin 23 respectively.

[0096] At this step, there is a gap between the outer wall of the pin 23 and the guide 21 on the side where the locking port 211 is located. The thickness of the fastening arm 242 is slightly larger than the gap between the outer wall of the pin 23 and the guide 21. With the help of a tool, the limiting block 24 can be used to hammer the fastening arm 242 between the pin 23 and the guide 21. The fastening arm 242 is in close contact with the pin 23 and the guide 21 respectively (such as an interference fit), locking the locking part 221. The locking part 221 will not wobble slightly. The battery base 100 and the battery box 200 can maintain a reliable and stable locking relationship, so that the battery box 200 is fixed in position and will not wobble, improving the stability of the assembly structure of the battery base 100 and the battery box 200.

[0097] Step S4: Fix the limiting block 24 to the guide body 21 using fastener 25.

[0098] A nut can be fixedly installed on the inner wall of the guide body 21. The fastener 25 can be a bolt, and the stud of the bolt passes through the through hole 2411 on the limiting block 24 and is threaded to the nut. The nut can be pre-welded to the outer wall of the guide body 21, or the nut and the guide body 21 can be separate parts. The nut is placed inside the guide body 21 when the limiting block 24 is assembled, so as to facilitate the threaded connection with the stud of the bolt.

[0099] By using the above-described battery box 200 locking method, the battery base 100 and the battery box 200 are locked together to form an integrated battery system. The battery base 100 and the battery box 200 of this battery system are usually not separated and are used as a whole.

[0100] In this application, one or more battery boxes 200 can be installed on a battery base 100. When multiple battery boxes 200 are installed on the battery base 100, the battery box 200 only needs to be removed and replaced when it malfunctions or ages and needs to be replaced. The method for removing the battery box 200 is to first remove each limiting block 24, then use a tool to act on the pin 23 to disengage the pin 23 from the locking part 221, and then rotate the locking tongue 22 to disengage the locking part 221 from the battery box 200. At this time, the battery box 200 can be moved away with the help of lifting equipment or a forklift.

[0101] Example 3

[0102] like Figures 1 to 13 As shown in the illustration, this application provides a battery system including: the aforementioned battery base 100, a first connecting component 300, a charging / discharging socket 500, and at least two battery cases 200. The battery cases 200 are disposed on the battery base 100, with each battery case 200 arranged sequentially, forming a gap cavity 400 between adjacent battery cases 200. The first connecting component 300 is located in the gap cavity 400 and connects to adjacent battery cases 200. The charging / discharging socket 500 is disposed on the battery base 100 and at least partially located in the gap cavity 400, and is electrically connected to the battery cases 200. The charging / discharging socket 500 is positioned between two battery cases 200, fully utilizing the space between them. The gap cavity 400 between the two battery cases 200 can serve as a maintenance channel, facilitating the inspection and maintenance of the battery cases 200.

[0103] like Figure 2 and Figure 3 As shown, the first connecting component 300 is located between the two battery boxes 200 and connects the two battery boxes 200, thereby connecting the two battery boxes 200 to form an integrated structure, which improves the structural stability and product quality of the battery system and ensures the structural strength and stability of the system as a whole during transportation and hoisting.

[0104] The battery system of this application includes a battery base 100 and at least two battery boxes 200, increasing the battery system's capacity and meeting the short-term usage needs of most scenarios. The battery boxes 200 in this application can be new or existing ones, thereby increasing the total capacity of the battery system, improving current output capability, and achieving secondary utilization. This allows the battery boxes 200 to continue to provide value, extending resource lifespan, reducing the environmental and cost pressures of producing new batteries, and conserving resources.

[0105] In some possible implementations, such as Figure 3As shown, the battery box 200 has a main body and a top frame 210 disposed on the top of the main body. The main body is connected to the battery base 100. The top frame 210 is located on the side of the main body away from the battery base 100. A first connecting assembly 300 is detachably connected to the top frame 210 of the battery box 200. The top frame 210 is used to connect with lifting equipment and provide a lifting point for the lifting equipment. The bottom of the battery box 200 is fixed to the battery base 100. The top frames 210 are connected to each other through the first connecting assembly 300, assembling each battery box 200 and the battery base 100 into a single structure.

[0106] In some possible implementations, the first connecting assembly 300 includes a plurality of connecting rods 310, each located in the gap cavity 400. The connecting rods 310 are spaced apart sequentially along the length of the battery box 200, and both ends of each connecting rod 310 are connected to the top frame 210 of the corresponding battery box 200 by fasteners 25. A mounting plate may be provided at the end of the connecting rod 310, and one end of the fastener 25 passes through the mounting plate and is connected to the top frame 210. The fastener 25 can be a bolt. The connecting rods 310 are detachably connected to the top frame 210 by bolts, facilitating assembly and disassembly.

[0107] In some possible implementations, such as Figure 3 As shown, the top frame 210 includes a lifting beam 2102 and multiple uprights 2101. The lifting beam 2102 is used to combine with the gripper of the lifting equipment to provide a gripping position. The lifting beam 2102 is connected to the main housing via the uprights 2101. A first connecting assembly 300 is connected to the lifting beam 2102. Each link 310 of the first connecting assembly 300 is vertically connected to the lifting beam 2102, and the links 310 are spaced apart sequentially along the length of the lifting beam 2102.

[0108] In some possible implementations, such as Figure 7 As shown, the battery base 100 has a second connecting component 1b and at least two base units 1a, with each base unit 1a arranged sequentially at intervals. The second connecting component 1b is located between adjacent base units 1a, and its two ends are respectively connected to the two adjacent base units 1a.

[0109] The battery base 100 of this application can be a dual-station or multi-station battery base 100, and each base unit 1a is connected to form an integral structure through a second connecting component 1b. The second connecting component 1b may include short beams, two of which are located between two base units 1a and are respectively connected to the two base units 1a.

[0110] In some possible embodiments, the battery base 100 has a universal beam 14, a portion of which is a structural beam of one base unit 1a, and another portion of which is a structural beam of another base unit 1a. The two base units 1a share a single universal beam 14, which is a single, weld-free beam, thereby enhancing the structural strength of the battery base 100 and simplifying its structure.

[0111] In some possible implementations, such as Figure 11 and Figure 12 As shown, the battery base 100 includes a lower frame 12, an upper frame 11, and a column 13 connecting the upper frame 11 and the lower frame 12. The lower frame 12 is a straight frame. The battery system provided in this embodiment can be placed directly on the ground at the target location, and the lower frame 12 can be stably supported on the ground, eliminating the need to build a concrete floor in advance at the target location, thus facilitating customer use.

[0112] In some possible implementations, such as Figure 11 As shown, the battery base 100 includes a long box 15 located between the upper frame 11 and the lower frame 12. The long box 15 is connected to both the upper frame 11 and the lower frame 12, and has insertion arm slots. These insertion arm slots are used for forklift transfer of the battery system. Two long boxes 15 can be installed on the battery base 100, spaced apart and arranged parallel to each other. The battery system of this application supports both lifting equipment transfer and forklift transfer. When transferring the energy storage system by forklift, the two forklift arms can be inserted into the insertion arm slots in the two long boxes 15 on the battery base 100, and then the forklift can transfer the battery system.

[0113] In some possible implementation schemes, combined Figure 2 and Figure 9 As shown, the battery box 200 has a cooling air inlet 220 and a hot air outlet 230. In two adjacent battery boxes 200, the cooling air inlets 220 are located on opposite side walls, and the hot air outlets 230 are located on opposite side walls. A cooling unit is installed inside the battery box 200, and the cooling unit is equipped with a fan. After the fan is started, it can drive the hot air that has exchanged heat with the water-cooled unit to be discharged through the hot air outlet 230. The external cooling air inlet 220 enters the battery box 200 through the gap cavity 400 between the two battery boxes 200.

[0114] The hot air exhaust ports 230 on the battery box 200 all face outward, that is, the side away from the gap cavity 400. The cooling air inlets 220 of the two battery boxes 200 are connected to the gap cavity 400 between them, ensuring that the external cooling air can enter smoothly. The setting of the gap cavity 400 can also support after-sales service and ensure sufficient operating space.

[0115] In some possible implementations, the charging / discharging socket 500 includes at least two charging / discharging interface groups, each of which is electrically connected to a corresponding battery box 200. That is, each battery box 200 is independent of each other, ensuring that the charging and discharging of the two battery boxes 200 can be carried out independently, and that the overall function is not affected by the low power or maintenance required by a single battery box 200.

[0116] Example 4

[0117] like Figures 1 to 13 As shown in the illustration, this application provides a battery system including: the aforementioned battery base 100, battery locking mechanism 2, and battery box 200. A vehicle-end locking engagement seat 16 is provided at the bottom of the battery base 100, the vehicle-end locking engagement seat 16 having a locking hole 1611, the vehicle-end locking engagement seat 16 being used for locking engagement with the vehicle-end locking mechanism on a power transmission vehicle. The battery locking mechanism 2 is disposed on the battery base 100, and at least partially protrudes from the top of the battery base 100. The battery locking mechanism includes a guide body, a locking tongue, a pin, and a limiting block, etc. The battery box 200 is supported on the battery base 100 and is locked engagement with the battery locking mechanism 2.

[0118] The battery system of this application is provided with a vehicle-end locking mating seat 16 at its bottom, while a vehicle-end locking mechanism is provided on the power transmission vehicle. When the battery system is placed on the power transmission vehicle, the vehicle-end locking mechanism can lock or unlock the vehicle-end locking mating seat 16, effectively securing the battery system during transportation and improving the transportation safety of the battery system. The mating structure of the vehicle-end locking mechanism and the vehicle-end locking mating seat 16 also facilitates the assembly and disassembly of the battery system and the power transmission vehicle, improving the transfer efficiency of the battery system.

[0119] In some possible implementation schemes, combined Figure 11 and Figure 12 As shown, the battery base 100 includes a lower frame 12, an upper frame 11, and a column 13 connecting the upper frame 11 and the lower frame 12. A vehicle-end locking engagement seat 16 is disposed on the lower frame 12. When the battery base 100 is supported on the chassis of the electric vehicle, the lower frame 12 directly adheres to the chassis, and the vehicle-end locking engagement seat 16 on the lower frame 12 and the vehicle-end locking engagement mechanism on the chassis are locked together. The battery locking mechanism 2 is disposed on the upper frame 11 and is used to lock the battery box 200, fixing the battery box 200 and the battery base 100 together to form an integral structure.

[0120] In some possible implementations, the lower frame 12 includes a plurality of side beams 121, each side beam 121 being arranged sequentially along the circumference of the battery base 100, and a vehicle end locking mating seat 16 being disposed between two adjacent side beams 121, and the vehicle end locking mating seat 16 being connected to two adjacent side beams 121 respectively.

[0121] The side beams 121 of the lower frame 12 can be arranged in a rectangular pattern, while the vehicle end locking seats 16 can be located at the four corners of the rectangle. The vehicle end locking seats 16 connect to two perpendicular side beams 121 respectively, thereby strengthening the structural strength of the battery base 100.

[0122] In some possible implementations, the vehicle-end locking mating seat 16 has a cavity, and the locking hole 1611 communicates with the cavity. The locking hole 1611 is located on the side of the lower frame 12 opposite to the upper frame 11. That is, the locking hole 1611 is located below the lower frame 12, and also below the vehicle-end locking mating seat 16, which facilitates the insertion of the vehicle-end locking mechanism on the electric vehicle chassis into the locking hole 1611 to lock and fix the battery base 100.

[0123] In some possible implementations, the vehicle end locking mating seat 16 has a base plate 161, a top plate 162 and a side plate 163 disposed between the base plate 161 and the top plate 162. The base plate 161 is provided with the lock hole 1611, the side beam 121 is welded to the side plate 163, and a through opening communicating with the cavity is provided on a portion of the side plate 163.

[0124] The vehicle-end locking mating seat 16 and the vehicle-end locking mechanism on the trolley in this application can directly adopt mature products available on the market. For example, the vehicle-end locking mechanism can be a twist lock (or rotary lock), and its structure can refer to the twist lock on a container. Its core principle is to achieve locking by rotating the mushroom-shaped lock head (rotary locking component). For example, the vehicle-end locking mechanism can include a cast steel housing, a mushroom-shaped lock head (rotary locking component), and a handle. The cast steel housing can be installed on the trolley. The mushroom-shaped lock head is rotatably mounted on the cast steel housing. The mushroom-shaped lock head has a roughly T-shaped structure, and the handle is connected to the mushroom-shaped lock head to drive its rotation. The vehicle-end locking mating seat 16 is a corner piece located at the four corners of the bottom of the battery base 100, with locking holes 1611. During the placement of the battery system on the power transmission vehicle, the position of the battery system is adjusted so that the four mushroom-shaped lock heads on the power transmission vehicle are inserted into the locking holes 1611 on the corresponding corner pieces. Then, the operator rotates the handle, causing the mushroom-shaped lock heads to rotate at a certain angle, so that the length direction of the mushroom-shaped lock head and the extension direction of the locking hole 1611 form an angle. If the two are perpendicular, the mushroom-shaped lock head locks the vehicle-end locking mating seat 16. At this time, even if an upward lifting force is applied to the battery box 200, the battery system will not detach from the power transmission vehicle due to the limiting effect of the mushroom-shaped lock head. The locked and unlocked states can be switched by rotating the handle. The vehicle-end locking mechanism and vehicle-end locking mating seat 16 of this application directly adopt commercially available products (twist locks), the structural principles of which are widely disclosed in the prior art, and will not be elaborated upon here.

[0125] In some possible implementations, at least part of the column 13 is welded to the vehicle end locking seat 16.

[0126] In this embodiment, the uprights 13 located at the four corners of the battery base 100 can be directly welded to the top plate 162 of the vehicle end locking mating seat 16. The vehicle end locking mating seat 16 can be welded to the uprights 13 and the side beams 121 respectively, which significantly improves the structural strength of the battery base 100.

[0127] In some possible implementations, the battery base 100 includes a long box 15 located between the upper frame 11 and the lower frame 12. The long box 15 is connected to both the upper frame 11 and the lower frame 12. The long box 15 has insert arm slots for easy forklift transport of the battery system. Two long boxes 15 can be installed on the battery base 100, spaced apart and arranged parallel to each other. The battery system of this application supports both lifting equipment and forklift transport. When transferring the energy storage system by forklift, the two forklift arms can be inserted into the insert arm slots in the two long boxes 15 on the battery base 100, and then the forklift can transfer the battery system.

[0128] In some possible implementations, the battery system includes an adapter plate having two perpendicular plates, one plate welded to the elongated box 15 and the other plate welded to the upper frame 11 or lower frame 12. Each elongated box 15 can be secured to the battery base 100 by multiple adapter plates.

[0129] In some possible implementations, such as Figure 1 and Figure 2 As shown, the battery system includes at least two battery boxes 200. Each battery box 200 includes a box body and a sealing plate 240. The box body of each battery box 200 is fixed to the battery base 100, and the box bodies are arranged sequentially along the battery base 100, forming a gap cavity 400 between adjacent box bodies. The sealing plate 240 is connected to the box body, and at least part of the sealing plate 240 simultaneously covers two adjacent box bodies. Each sealing plate 240 blocks the gap cavity 400 on both sides perpendicular to the arrangement direction of the box bodies.

[0130] Adjacent battery boxes 200 share the same sealing plate 240, which connects adjacent battery boxes 200, giving the two battery boxes 200 a unified assembly effect. Furthermore, the shared sealing plate 240 simplifies the assembly structure. The tops of the two battery boxes 200 are not covered by the sealing plate 240, and the top of the cavity 400 formed between the two battery boxes 200 is open.

[0131] This application also provides a power transmission vehicle, including a chassis and a vehicle-end locking mechanism. The vehicle-end locking mechanism is disposed on the chassis and includes a rotary locking member. When a battery system with a vehicle-end locking mating seat 16 is placed on the chassis, the rotary locking member of the vehicle-end locking mechanism is inserted into the locking hole 1611 of the vehicle-end locking mating seat 16. The rotary locking member can rotatably engage or disengage the vehicle-end locking mating seat 16. The mating structure of the vehicle-end locking mechanism and the vehicle-end locking mating seat 16 has been described in detail above and will not be repeated here.

[0132] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
