It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment," "in some embodiments," or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] Please also refer to Figures 1 to 3, the battery stack structure that is easy to quickly disassemble and assemble provided by the embodiment of the present invention is now described. The battery stack structure that is easy to quickly disassemble and assemble provided by the embodiment of the present invention includes a carrier 1, a guide assembly 2, a first end plate 3, a second end plate 4, a core 5 and a pressure mechanism 6. The carrier 1 is a plate-like structure, the guide assembly 2 is arranged on the carrier 1, the first end plate 3 is arranged on the guide assembly 2, the second end plate 4 is parallel to the first end plate 3 and is arranged at intervals, and the accommodating space between the first end plate 3 and the second end plate 4 can accommodate the core 5, and the core 5 is arranged on the second end plate 4. It should be noted that the core 5 can also be arranged on the first end plate 3, and the core 5 can also be arranged on the first end plate 3 and the second end plate 4 at the same time. The second end plate 4 is slidably connected to the guide assembly 2. Under the action of external force, the guide assembly 2 can guide the second end plate 4 to approach or move away from the first end plate 3. The pressure mechanism 6 is used to provide a force that pushes the second end plate 4 toward the first end plate 3. The pressure mechanism 6 can apply a force to the second end plate 4 to compress the core 5, so as to fasten the core 5 between the first end plate 3 and the second end plate 4. When the stack structure needs to be assembled, the core 5 only needs to be placed in the accommodating space between the first end plate 3 and the second end plate 4, and the second end plate 4 is pushed toward the first end plate 3 by the pressure mechanism 6. At the same time, the pressure mechanism 6 applies a force to the second end plate 4 to compress the core 5, so that the core 5 can be fastened between the first end plate 3 and the second end plate 4. When the stack structure needs to be disassembled, it is only necessary to release the force applied by the pressure mechanism 6 to the second end plate 4, and the pressure mechanism 6 drives the second end plate 4 to move in the direction away from the first end plate 3. The core 5 can be conveniently removed from the second end plate 4 without the aid of special tools. The core 5 is a common structure, consisting of two insulating plates, two current collecting plates, and n single-section stacks, where n ≥ 1; the first end plate 3 and the second end plate 4 serve as the two end plates of the stack, respectively. It should be noted that, especially in the laboratory test of the stack structure, when the core 5 needs to be frequently disassembled and assembled, there is no need to tighten or unscrew the nuts on the screw rods in a certain order multiple times, making the disassembly and assembly process of the stack simpler and more convenient, significantly improving the speed at which operators can disassemble and install the stack, thereby improving testing efficiency, and stably and reliably ensuring the uniformity of the pressure applied to the core 5, making the experimental data more reliable.

[0038] The embodiment of the present invention provides a fuel cell stack structure that is easy to disassemble and assemble quickly. Compared with the prior art, when assembling the fuel cell stack structure, it is only necessary to place the core 5 in the accommodation space between the first end plate 3 and the second end plate 4, and apply a force to the second end plate 4 to compress the core 5 by the pressure mechanism 6, so that the core 5 can be quickly and stably fastened between the first end plate 3 and the second end plate 4, and the uniformity of the force on the core 5 between the first end plate 3 and the second end plate 4 can be fully ensured. After assembly, Figure 1As shown, after completion, the entire stack structure that is easy to quickly disassemble and assemble is flipped over so that the core 5 is in a vertical state, and subsequent testing can be carried out. When disassembling the stack structure, the entire stack structure that is easy to quickly disassemble and assemble is flipped over so that the core 5 is in a horizontal state. It is only necessary to use the pressure mechanism 6 to drive the second end plate 4 to move a distance away from the first end plate 3, and release the fastening force of the first end plate 3 and the second end plate 4 on the core 5, so that the core 5 can be easily removed from the second end plate 4. Especially in the use scenario where the stack needs to be frequently disassembled and assembled during laboratory testing of the stack structure, the disassembly and assembly process of the stack is simpler and more convenient, which can significantly improve the speed of the operator disassembling and installing the stack, improve the test efficiency and the reliability of the experimental data. In addition, compared with the method of assembling the stack using a screw fastening structure, the average time for disassembling and installing the stack can be shortened by more than 30%, while avoiding the need to tighten multiple screws separately in a certain order, and the pressure applied to the stack is more uniform.

[0039] It should be noted that in some embodiments, the pressure-applying mechanism 6 includes a press and a pressure sensor. The press is disposed on the support 1, and the pressure sensor is disposed on the press or the second end plate 4, so that the pressure sensor can detect the pressure value applied by the press on the second end plate 4, thereby enabling the press to quickly and evenly compress the core 5 between the first end plate 3 and the second end plate 4 to a suitable pressure range, ensuring that the various plates of the stack structure are more evenly stressed. It should be noted that the press includes but is not limited to an electric screw press, a hydraulic press, or a manual screw press.

[0040] It can be understood that in some other embodiments, the pressure-applying mechanism 6 includes a jack and a pressure sensor, the jack is arranged on the supporting member 1, and the pressure sensor is arranged on the jack or the second end plate 4. The pressure sensor can detect the pressure value applied by the jack on the second end plate 4, so that the press can quickly and evenly press the core 5 between the first end plate 3 and the second end plate 4 to a suitable pressure range, ensuring that the plates of the stack structure are evenly stressed.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 3In some embodiments, the guide assembly 2 includes a plurality of vertically arranged guide columns 21, and the plurality of guide columns 21 are arranged on the carrier 1 in parallel and at intervals, and each guide column 21 has a first end facing away from the carrier 1 and a second end close to the carrier 1. The first end plate 3 is detachably connected to the first end of each guide column 21, so as to facilitate the disassembly and assembly of the first end plate 3 and each guide column 21. When the first end plate 3 is fixedly installed on the first end of the guide column 21, since the first ends of the guide columns 21 are located on the same horizontal plane, the horizontality of the installation of the first end plate 3 can be ensured, thereby ensuring force balance. The second end of each guide column 21 is connected to the carrier 1, so that each guide column 21 can support and fix the first end plate 3 on the carrier 1.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, each guide column 21 includes a first screw segment 211 connected to the first end of the guide column 21. The stack structure that is convenient for quick disassembly and assembly includes a fastening nut 7 for screwing onto the first screw segment 211. The fastening nut 7 can fasten the first end plate 3 to the first end of the guide column 21, thereby facilitating the installation and disassembly of the first end plate 3.

[0043] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, each guide post 21 further includes a second screw segment 212 connected to the second end of the guide post 21. The carrier 1 is provided with an internal threaded hole 11 for threaded connection with the second screw segment 212. By simply screwing the second screw into the internal threaded hole 11, a stable connection between the guide post 21 and the carrier 1 can be achieved. When the guide post 21 needs to be removed from the carrier 1, it is only necessary to unscrew the second screw from the internal threaded hole 11. It should be noted that the connection method between the guide post 21 and the carrier 1 can be, but is not limited to, the above-mentioned threaded connection method. For example, the guide post 21 and the carrier 1 can also be fixedly connected by welding or other connection methods.

[0044] Please refer to Figure 1 and Figure 3 In some embodiments, the carrier 1 is a carrier plate, and the projections of multiple guide columns 21 connected in sequence on the carrier plate can form a regular polygon. The pressure mechanism 6 is provided on the carrier plate and is located at the geometric center of the regular polygon. In the process of the pressure mechanism 6 applying force to the second end plate 4, the force on the second end plate 4 is made more uniform, so that the press can quickly and evenly press the core 5 between the first end plate 3 and the second end plate 4 to a suitable pressure range, ensuring that the plates of the stack structure are evenly stressed.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, each guide column 21 further includes a support section 213 for connecting to the carrier 1, a guide section 214 connected to the support section 213, and a positioning section 215 connected to the end of the guide section 214 facing away from the support section 213. The positioning section 215 constitutes the first end of the guide column 21, and the end of the support section 213 facing away from the guide section 214 constitutes the second end of the guide column 21. The first end plate 3 is provided with a positioning hole 31 for mating with the positioning section 215. Since multiple positioning sections 215 are located on the same horizontal plane, it is only necessary to match each positioning hole 31 on the first end plate 3 with the corresponding positioning section 215. This not only ensures the horizontal installation of the first end plate 3 and improves the force balance, but also enhances the stability of the first end plate 3 when positioned on the first end of each guide column 21. The second end plate 4 is provided with a guide slide hole 41 for slidingly fitting on the guide section 214. By sliding the multiple guide slide holes 41 on the second end plate 4 onto the corresponding guide sections 214, the second end plate 4 can be guided by the guide column 21 to move in a direction perpendicular to the first end plate 3 or the second end plate 4, so that the press can quickly and evenly press the core 5 between the first end plate 3 and the second end plate 4 to a certain suitable pressure range, ensuring that the plates of the stack structure are evenly stressed.

[0046] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, the cross-sectional area of ​​the positioning section 215 is smaller than the cross-sectional area of ​​the guide section 214, so that a first limiting step 216 for supporting and limiting the first end plate 3 is formed at the connection between the positioning section 215 and the guide section 214. Since the multiple first limiting steps 216 are located on the same horizontal plane, it is only necessary to insert the positioning section 215 on the first end of each guide column 21 into the corresponding positioning hole 31 on the first end plate 3. The first end plate 3 can be supported and limited by the multiple first limiting steps 216, which can not only ensure the horizontality of the installation of the first end plate 3 and improve the balance of force, but also enhance the stability of the first end plate 3 positioned and installed on the first end of each guide column 21.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 3In some embodiments, the cross-sectional area of ​​the guide segment 214 is smaller than that of the support segment 213. This forms a second limiting step 217 at the junction of the guide segment 214 and the support segment 213, which is used to abut and limit the second end plate 4. After the multiple guide sliding holes 41 on the second end plate 4 are slidably fitted onto the corresponding guide segments 214, the second limiting steps 217 on each guide column 21 provide a retaining effect on the second end plate 4. Furthermore, the support segment 213 is provided with a snapping portion 218 for engaging with a wrench, facilitating the wrench's grip and rotation of the support segment 213.

[0048] Please refer to Figure 1 and Figure 3 In some embodiments, the first end plate 3 is a liquid inlet and outlet end plate, on which a positive electrode liquid inlet hole 32, a negative electrode liquid inlet hole 33, a positive electrode liquid outlet hole 34 and a negative electrode liquid outlet hole 35 are respectively provided. The battery stack structure that is convenient for quick disassembly and assembly also includes a first liquid inlet pipe 8 for communicating with the positive electrode liquid inlet hole 32, a second liquid inlet pipe 9 for communicating with the negative electrode liquid inlet hole 33, a first liquid outlet pipe 10 for communicating with the positive electrode liquid outlet hole 34, and a second liquid outlet pipe 20 for communicating with the negative electrode liquid outlet hole 35. The first liquid inlet pipe 8, the second liquid inlet pipe 9, the first liquid outlet pipe 10 and the second liquid outlet pipe 20 are respectively connected to the liquid inlet and outlet end plates.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
