[0033] The utility model provides a combined inspection module 1.

[0034] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 The combined inspection module 1 of this embodiment includes a shell 100, and a voltage inspection board 10 is integrated and installed in the inner cavity of the shell 100. The voltage inspection board 10 is provided with a plurality of connectors 11. A plurality of spaced-apart partitions 12 are provided on the shell 100. A connecting gap 13 is formed between any two adjacent partitions. Each connector 11 is arranged in a one-to-one correspondence with each connecting gap 13, so that the battery electrode 30 inserted into the connecting gap 13 is connected to the corresponding connector 11. A guide slope 14 is formed on the side wall of any partition 12, which is inclined from bottom to top toward another partition 12 adjacent to it.

[0035] It can be understood that the fuel cell includes a plurality of battery pole pieces 30 arranged at intervals. During assembly, the combined inspection module 1 is pressed down from above the battery pole pieces 30, and the battery pole pieces 30 are guided by the guide slopes 14 so that each battery pole piece 30 is correspondingly inserted into each connecting gap 13, and then connected to the connecting piece 11 in the connecting gap 13.

[0036] In the technical solution of the utility model, a voltage inspection board 10 is integrated in the inner cavity of the shell 100 to replace the external voltage inspection meter. The voltage inspection board 10 is directly electrically connected to the battery electrode 30 through the connector 11 and collects the voltage information of the fuel cell. There is no need to connect the connector 11 to the voltage inspection board 10 through an additional transmission line 104, which reduces the number of wiring and occupied space, simplifies the equipment structure, and reduces costs. At the same time, a connection gap 13 is formed by the partition 12, so that each battery electrode 30 corresponds to a connection gap 13, and then the battery electrode 30 is guided by the guide slope on the side wall of the partition 12, so that the connector 11 and the battery electrode 30 are aligned during assembly, which reduces the probability of damage to the connector 11 or the battery electrode 30 and improves assembly efficiency.

[0037] In one embodiment, a limiting member 15 is formed at one end of the separator 12, a guide slope 14 is formed on the side wall of the limiting member 15, the limiting member 15 includes a straight section 151 and a limiting section 152, the limiting section 152 is connected to the separator 12, the straight section 151 is connected to one end of the limiting section 152 away from the separator 12, the width of the limiting section 152 is gradually reduced in the direction away from the separator 12, and the minimum spacing between any two adjacent limiting sections 152 is greater than the thickness of the battery electrode 30. The width of the limiting section 152 is gradually reduced, so that the part with the largest width, that is, the minimum spacing between the two limiting sections 152, is used to limit the battery electrode 30, and the smaller width part of the limiting section 152 and the straight section 151 can be used to guide the battery electrode 30, and the overall weight and volume of the limiting member 15 can also be reduced.

[0038] Further, the separator 12 includes a separator section 121 and a fixed section 122, the separator section 121 is connected between the fixed section 122 and the limiting section 152, the width of the fixed section 122 is the same as the maximum width of the limiting section 152, the width of the separator section 121 is smaller than the width of the fixed section 122, and a guide slope 14 is formed on the side wall of the fixed section 122. The fixed section 122 and the limiting section 152 are respectively arranged at opposite ends of the separator section 121 to limit both ends of the battery electrode 30, thereby improving the stability of the connection between the battery electrode 30 and the combined inspection module 1, and the separator section 121 is mainly used to divide each connection gap 13, so the width of the separator section 121 can be smaller than the width of the fixed section 122, so as to reduce the overall weight and volume of the separator 12.

[0039] Furthermore, a reinforcing rib 123 is provided on the partition section 121, the width of the reinforcing rib 123 is the same as the width of the fixing section 122, and a guide slope 14 is formed on the side wall of the reinforcing rib 123. The reinforcing rib 123 is located in the middle of the partition section 121, and is used to further fix the battery pole piece 30, improve the stability of the connection between the battery pole piece 30 and the combined inspection module 1, and at the same time, a guide slope 14 is also provided on the side wall of the reinforcing rib 123, which further reduces the difficulty of assembly.

[0040] In one embodiment, the reinforcing ribs 123 divide the connection gap 13 into a first sub-gap 131 and a second sub-gap 132, and each connector 11 is staggeredly arranged in the first sub-gap 131 and the second sub-gap 132. Specifically, the connector 11 in the connection gap 13 of the first row is located in the first sub-gap 131, the connector 11 in the connection gap 13 of the second row is located in the second sub-gap 132, and the connector 11 in the connection gap 13 of the third row is located in the first sub-gap 131, and so on. Through the staggered design of the connector 11, the balance of the connection between the battery electrode 30 and the combined inspection module 1 can be improved, thereby improving its stability.

[0041] In one embodiment, a transmission interface 101 is provided on the voltage inspection board 10, and a through hole 102 connected to the transmission interface 101 is opened at a position corresponding to the transmission interface 101 on the shell 100, and a connecting seat 103 is embedded in the through hole 102. The connecting seat 103 is installed on the voltage inspection board 10, and a mounting hole for inserting a transmission line 104 is opened on the connecting seat 103. The transmission line 104 inserted into the mounting hole is electrically connected to the transmission interface 101 through the connecting seat 103, and the voltage data collected by the connector 11 is sent to an external device. A through hole 102 is opened on the shell 100 so that the transmission line 104 can pass through the through hole 102 and extend into the installation cavity, and then the connecting seat 103 is installed at the transmission interface 101. The transmission line 104 is electrically connected to the voltage inspection board 10 through the connecting seat 103 instead of being directly connected to the voltage inspection board 10. This can improve the stability of the connection of the transmission line 104 and prevent the voltage inspection board 10 from being damaged when installing the transmission line 104, thereby extending the service life of the voltage inspection board 10.

[0042] Furthermore, the housing 100 is inwardly recessed at positions corresponding to the connection gaps 13 to form a card slot 16, and the housing 100 is provided with a buckle 17 at positions corresponding to the card slot 16, and the buckle 17 is used to clamp with the card slot 16 to fix the battery pole piece 30 located in the connection gap 13. Through the cooperation of the second buckle 17 and the second card slot 16, the connection between the pole piece located in the accommodating cavity and the lower housing is made more stable, preventing the pole piece from coming out of the lower housing and causing the voltage data of the fuel cell to be missed.

[0043] Specifically, the buckle 17 is movably connected to the shell 100 through a reset component 173. The buckle 17 includes a pressing end 171 and a locking end 172 for locking with the slot 16. The pressing end 171 is spaced apart from the shell 100 to form a pressing space; the pressing end 171 can move from the initial position to the working position when pressed, and drive the locking end 172 to disengage from the slot 16 to release the battery electrode 30 and cause the reset component 173 to be compressed and deformed; the reset component 173 is used to push the pressing end 171 from the working position to the initial position through its elastic restoring force when the pressing end 171 is released, and drive the locking end 172 to insert into the slot 16 and clamp with the slot 16 to fix with the battery electrode 30.

[0044] It can be understood that when the pressing end 171 is in the initial position, the reset component 173 is in a relaxed state, the snap-fit ​​end 172 is in the card slot 16, and fixes the battery pole piece 30 in the accommodating cavity. When the pressing end 171 is pressed and moved to the working position, the reset component 173 is pressed and deformed, and the snap-fit ​​end 172 is separated from the card slot 16, which makes it easy to insert or remove the pole piece into or out of the accommodating cavity. Through the cooperation between the buckle 17 and the card slot 16, the locking and loosening between the pole piece and the housing 100 are achieved, which simplifies the assembly process, improves the assembly efficiency, and facilitates the removal of the battery inspection module for maintenance.

[0045] See also Figure 5 The utility model also provides a battery inspection device 2, including a CVM control signal output module and a plurality of the above-mentioned combined inspection modules 1. The voltage inspection board 10 of the combined inspection module 1 is provided with an output interface. Among the plurality of combined inspection modules 1, two transmission interfaces 101 are electrically connected to the CVM control signal output module through a transmission line 104 respectively, and the remaining transmission interfaces 101 are sequentially connected in series through the transmission lines 104. This solution further reduces the number and occupied volume of the transmission lines 104 and reduces the difficulty of wiring by setting a plurality of combined inspection modules 1, and connecting the output interfaces on each combined inspection module 1 in series, and only reserving two interfaces to be connected to the CVM control signal output module. At the same time, the specific structure of the combined inspection module 1 refers to the above-mentioned embodiment. Since the battery inspection device 2 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0046] In one embodiment, a fixing groove 21 is provided on the top of the shell 100 of each combined inspection module 1, and a plurality of fixing grooves are connected to form a fixed space, in which a fixing rod is provided, the fixing rod is pressed against the side wall of the fixed space, and the two ends of the fixing rod extend out of the fixed space and are fixed to an external device. The top of the shell 100 of each combined inspection module 1 is fixed to an external device through a fixing rod, so that the combined inspection module 1 can be fixed on the battery pole piece 30 of the fuel cell more stably, and will not be disconnected from the battery pole piece 30 due to shaking, etc., so that the voltage inspection board 10 can obtain the voltage data of the fuel cell at all times, thereby improving the comprehensiveness of the detection and ensuring the safety of the fuel cell.
