[0036] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 3In some embodiments, the inspection module 10 includes a probe 100 and a metal sheet 200. One end of the probe 100 is fixedly connected to the cell 600. For example, the cell 600 may be provided with a slot. The probe 100 may be round or square. One end of the probe 100 is inserted into the slot of the cell 600 and fixed, for example, by welding. When the probe 100 needs to be removed from the cell 600, a protrusion 150 may be provided on one end of the probe 100 to increase friction with the slot of the cell 600, making it difficult for the probe 100 to be removed from the cell 600. One end of the metal sheet 200 is snap-fitted to the other end of the probe 100. The metal sheet 200 may be in the form of a sheet and made of copper. This snap-fitting method not only facilitates the connection of the metal sheet 200 to the probe 100 by the operator, but also facilitates the electrical connection between the metal sheet 200 and the cell 600 and enables the transmission of electrical signals from the cell 600. In addition, since the probe 100 is fixed on the single cell 600, the probe 100 will not detach from the single cell 600 even when it encounters vibration. After the metal sheet 200 is clamped to the probe 100, when it encounters vibration, the metal sheet 200 may move relative to the probe 100, but it will not be disconnected from the probe 100, thereby losing the electrical signal of the single cell 600. Specifically, by connecting one end of the probe 100 to the single cell 600 and one end of the metal sheet 200 to the other end of the probe 100, it has higher reliability than the method of directly connecting the metal sheet 200 to the single cell 600. Specifically, the metal sheet 200 can be indirectly connected to the single cell 600 by clamping the probe 100, thereby avoiding the situation where the metal sheet 200 is directly connected to the single cell 600 and the contact between the metal sheet 200 and the single cell 600 is poor. Therefore, the inspection module 10 has higher reliability.

[0038] Furthermore, the metal sheet 200 and the probe 100 can be connected in such a way that one of the metal sheet 200 and the probe 100 is elastic and can hold the other in it, so that the other is not easily separated. Specifically, one of the metal sheet 200 and the probe 100 can be provided with a groove and the other can be provided with a buckle to be inserted into the groove. Figure 4In some embodiments, the probe 100 includes a first half needle 110 and a second half needle 120. The middle portion of the first half needle 110 is connected to the middle portion of the second half needle 120, which may be glued or otherwise bonded, so that one end of the first half needle 110 and the second half needle 120 are jointly clamped to the metal sheet 200. Specifically, the probe 100 is elastic. After the middle portions of the first half needle 110 and the second half needle 120 are connected to each other, their ends can be separated when an external force is applied. When the external force is removed, the ends return to their original positions. Therefore, by jointly clamping one end of the first half needle 110 and the second half needle 120 to the metal sheet 200, the probe 100 and the metal sheet 200 are securely connected, facilitating installation and removal of the inspection module 10 by personnel and improving the reliability of single-chip battery voltage detection.

[0039] Furthermore, during maintenance, the inspection module 10 often needs to be installed and disassembled, so the metal sheet 200 and the probe 100 need to be separated or connected multiple times. For convenience, the two can be connected together. Figure 4 In some embodiments, the other end of the probe 100 is provided with an opening 130, with a V-shaped cross-section along the width of the probe 100. It is conceivable that the V-shaped opening 130 facilitates the insertion of the metal sheet 200 into the opening for a snap-fit ​​connection. Without the V-shaped opening 130, it would take considerable time for the operator to align the metal sheet 200 with the probe 100 for a snap-fit ​​connection.

[0040] The opening 130 is convenient for the staff to clip the metal sheet 200 onto the probe 100, in order to strengthen the connection between the metal sheet 200 and the probe 100, so that the connection between the two is stable and can withstand certain external impacts, such as vibration. Figure 3 and Figure 4 In some embodiments, a clamping groove 140 is further provided at the other end of the probe 100. The clamping groove 140 is spaced apart from the opening 130 along the length of the probe 100, and the cross-section of the clamping groove 140 along the width of the probe 100 is diamond-shaped. Specifically, the probe 100 includes a first half pin 110 and a second half pin 120. One end of each of the first half pin 110 and the second half pin 120 is bent multiple times. When the first half pin 110 and the second half pin 120 are connected, a diamond-shaped clamping groove 140 is formed. When the metal sheet 200 is inserted into the clamping groove 140, the opposite ends of the clamping groove 140 abut against the metal sheet 200, thereby achieving a relatively stable connection and preventing the metal sheet 200 from being easily separated from the probe 100.

[0041] Please refer to Figure 2In some embodiments, the inspection module 10 further includes a fixing assembly 300, which includes a first fixing block 310 and a bracket 330. The bracket 330 is connected to the single cell 600, for example, the bracket 330 is connected to the end plate of the single cell 600. The first fixing block 310 is connected to the bracket 330, for example, the first fixing block 310 is connected to the bracket 330 by bolts. The first fixing block 310 is provided with a first through hole 311 and a second through hole 312, and the first through hole 311 and the second through hole 312 are connected. A portion of the metal sheet 200 is disposed in the first through hole 311, and a portion of the probe 100 is disposed in the second through hole 312. Specifically, the fixing assembly 300 can fix the metal sheet 200 so that the connection between the metal sheet 200 and the probe 100 is less affected by external forces. The bracket 330 is used to fix the first fixing block 310 and the second fixing block 320 to prevent the risk of unstable detection caused by vibration or shaking during voltage inspection. The first through hole 311 can be square in shape to fit the metal sheet 200, and the second through hole 312 can be circular in shape to fit the probe 100. Furthermore, when part of the probe 100 is disposed in the second through hole 312, space can be saved while also limiting and protecting the probe 100. Furthermore, when part of the metal sheet 200 is disposed in the first through hole 311, the first through hole 311 can also protect the metal sheet 200, preventing it from being exposed to the outside world.

[0042] Please refer to Figure 2 In some embodiments, the inspection module 10 further includes a terminal 400, one end of which is snap-fitted to the other end of the metal sheet 200, and the other end of the terminal 400 is electrically connected to the wire 500. The first fixing block 310 is provided with a first accommodating groove 313, which is connected to the first through-hole 311 and the second through-hole 312. Part of the terminal 400 is disposed in the first accommodating groove 313, such as the lower half of the terminal 400. Specifically, in order to reduce the space occupied by the inspection module 10, part of the terminal 400 can be disposed in the first accommodating groove 313. After one end of the metal sheet 200 is snap-fitted to the probe 100, it is disposed in the first through-hole 311. The other end of the metal sheet 200 can be snap-fitted to the terminal 400 and disposed in the terminal 400.

[0043] Please refer to Figure 7In some embodiments, the fixing assembly 300 further includes a second fixing block 320 and a fastener. The second fixing block 320 is provided with a second receiving groove 321. Part of the terminal 400 is disposed in the second receiving groove 321, such as the upper half of the terminal 400. The fastener is used to securely connect the second fixing block 320 to the bracket 330. Specifically, in order to protect the upper half of the terminal 400, the upper half of the terminal 400 is positioned in the second receiving groove 321. The fastener can be a bolt. The bracket 330 and the second fixing block 320 are provided with threaded holes. After the bolt passes through the threaded hole, the second fixing block 320 is fixed to the bracket 330.

[0044] Please refer to Figure 6 In some embodiments, the first fixing block 310 includes a first block 314 and a second block 315. Both the first block 314 and the second block 315 are provided with a first through hole 311 and a second through hole 312. The first block 314 is provided with a slide rail 3141, and the second block 315 is provided with a slide groove 3151. The first block 314 is slidably connected to the second block 315. Specifically, because the number of single cells 600 can be adjusted according to actual conditions, when the number of single cells 600 is adjusted, the number of probes 100 and metal sheets 200 is also adjusted, so that the number of probes 100, metal sheets 200, and single cells 600 is consistent. When the number of single cells 600 is small, a small number of probes 100 and metal sheets 200 are required, so the first fixing block 310 does not need to occupy too much space. As a result, the first block 314 or the second block 315 can be used alone to cooperate with the probes 100 and metal sheets 200. Furthermore, when the first block 314 and the second block 315 are required, in order to prevent the first block 314 and the second block 315 from moving relative to each other in the first direction, the design of the slide rail 3141 and the slide groove 3151 can be used to solve the problem. The first block 314 and the second block 315 can be fixed to the bracket 330, thereby preventing the first block 314 and the second block 315 from moving relative to each other in the second direction, wherein the first direction and the second direction are perpendicular to each other. It should be noted that the design of the slide rail 3141 and the slide groove 3151 can facilitate the installation of the first block 314 and the second block 315 to form the first fixed block 310.

[0045] Please refer to Figure 5In some embodiments, the bracket 330 is configured as a U-shaped block 331. The U-shaped block 331 includes a connecting portion 3311 and two protrusions 3312. The two protrusions 3312 are respectively connected to the ends of the connecting portion 3311. The two protrusions 3312 are arranged opposite each other so that the two protrusions 3312 and the connecting portion 3311 jointly define a U-shaped groove 3313. The first fixing block 310 is disposed in the U-shaped groove 3313. The connecting portion 3311 is provided with a perforation that communicates with the U-shaped groove 3313. The terminal 400 can pass through the perforation to connect with the metal sheet 200 in the first fixing block 310. Specifically, when the first fixing block 310 is disposed in the U-shaped groove 3313, it can save space, thereby preventing the first fixing block 310 from occupying too much space. The two protrusions 3312 can each be provided with a threaded hole, and the two protrusions 3312 can be connected to the two end plates of the single cell 600 using screws.

[0046] Please refer to Figure 8 In some embodiments, the fuel cell 20 includes a plurality of cells 600 and the inspection module 10 of any of the above embodiments. Specifically, due to the high reliability of the inspection module 10, the fuel cell 20 having the inspection module 10 has a high reliability.

[0047] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention.
