Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and more specifically, to a fuel cell inspection device. Background Technology

[0002] A fuel cell stack consists of multiple individual cells stacked sequentially. Changes in the operating environment and improper operation can cause changes in the voltage of each individual cell. Therefore, it is necessary to monitor the voltage of each individual cell and transmit the voltage signal to the fuel cell controller to determine the battery's operating status and thus determine appropriate response strategies. Currently, voltage monitoring devices are used to establish a connection with the fuel cell stack to collect the voltage of each individual cell.

[0003] A search revealed a fuel cell inspection device in the prior art, with patent publication number CN220983461U. The specification states that multiple battery inspection modules have their transmission interfaces connected in series, with only two transmission interfaces connected to an external recording device via transmission lines, further reducing the number of transmission lines and their volume, and lowering the difficulty of wiring.

[0004] However, when not in use, if the port is exposed to the air for a long time, dust and other impurities in the air can enter the interface. Because the internal space of the port is small, cleaning is inconvenient. If the transmission cable is plugged into the port at this time, the connection between the data cable and the port will be unstable due to the restriction of dust, resulting in poor contact and affecting the stability of data transmission. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fuel cell inspection device to solve the problem that when dust enters the socket, the connection between the data cable and the socket becomes unstable due to the restriction of dust, which in turn leads to poor contact and affects the stability of data transmission.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fuel cell inspection device, including a body, with two sockets fixedly connected to the front end of the body, two connecting rods slidably connected inside the sockets, a limiting ring sleeved on the outside of the connecting rods, an extension ring fixedly connected to the inside of the limiting ring, the limiting ring sleeved on the plug of the transmission line, the extension ring snapped onto the outside of the plug of the transmission line, two slots opened inside the limiting ring, a locking block snapped into the slot, and the locking block slidably connected inside the extension ring.

[0007] The connecting rod has two mounting slots inside. The end of the locking block away from the slot is fixedly connected to a mounting plate, and the other end of the mounting plate is fixedly connected to a pull rope. An elastic element is sleeved on the outside of the pull rope.

[0008] The connector has a groove inside, a sliding piece is fixedly connected to the rear end of the connecting rod, and an elastic element is sleeved on the outside of the connecting rod.

[0009] The mounting plate is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0010] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0011] The connecting rod has a placement groove on its front side, and a pull block is fixedly connected to the end of the pull rope away from the mounting plate. The pull block is slidably connected inside the placement groove.

[0012] The connecting rod is slidably connected inside the groove, and the sliding piece is slidably connected inside the groove.

[0013] One end of the second elastic element is fixedly connected to the inner wall of the slide groove, and the other end of the second elastic element is fixedly connected to the slide plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by installing a connecting rod with a limiting ring inside the socket and placing the limiting ring on the plug of the transmission line, the limiting ring can limit the connection, thereby ensuring that the plug of the transmission line can be stably connected to the socket, thus making the data transmission more stable.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a fuel cell inspection device, including a body 1, which is the main part of the device. The body 1 is equipped with an RS485 module, allowing the communication circuit of the inspection device to be connected to an RS485 bus. For faster communication rates (e.g., 115200bps), up to 32 inspection devices can be connected; for slower communication rates (e.g., 9600bps), up to 247 inspection devices can be connected. Data is transmitted using the Modbus-RTU communication protocol. The host computer sends a 03 function code read register instruction to each inspection device in a polling manner. After receiving the instruction, the inspection device reads the collected voltage and other data. The integrated data is sent to the host computer. The front end of the main body 1 is fixedly connected to two sockets 2. Inside the sockets 2, two connecting rods 3 are slidably connected. The sockets 2 provide installation space for the connecting rods 3. A limiting ring 4 is sleeved on the outside of the connecting rods 3. An extension ring 5 is fixedly connected to the inside of the limiting ring 4. The limiting ring 4 is sleeved on the plug of the transmission line. The extension ring 5 is snapped into the outside of the plug of the transmission line. With the cooperation of the limiting ring 4 and the extension ring 5, the plug of the transmission line can be stably inserted into the inside of the socket 2. Two slots 6 are opened inside the limiting ring 4. A locking block 7 is snapped into the inside of the slots 6. The locking block 7 is slidably connected inside the extension ring 5, so that the limiting ring 4 is limited to the outside of the connecting rod 3.

[0024] After the connector plug is inserted into the socket 2, the corresponding limiting ring 4 is fitted onto the outside of the connecting rod 3, so that the extension ring 5 fits into the groove on the plug and the limiting ring 4 fits tightly into the plug. Then, the two locking blocks 7 are moved to opposite sides, so that the locking blocks 7 engage with the inside of the locking slot 6, thereby limiting the limiting ring 4. Thus, the limiting ring 4 and the extension ring 5 can stably limit the plug. After use, the limiting ring 4 on the connecting rod 3 can be replaced with a blocking block, so that the blocking block can be inserted into the socket 2 and the locking block 7 can limit the blocking block, thereby reducing dust from entering the socket 2. Thus, the connecting rod 3 and the locking block 7 can serve multiple purposes.

[0025] Example 2: Based on Example 1, to facilitate the pulling of the locking block 7, two mounting grooves 8 are provided inside the connecting rod 3. A mounting piece 9 is fixedly connected to the end of the locking block 7 away from the locking groove 6. The mounting piece 9 is slidably connected inside the mounting groove 8, and the mounting groove 8 limits the movement of the mounting piece 9, allowing it to slide smoothly. A pull rope 10 is fixedly connected to the other end of the mounting piece 9. The pull rope 10 is used to pull the mounting piece 9 to move. The pull rope 10 is slidably connected inside the mounting groove 8, and the mounting groove 8 limits the movement of the pull rope 10. The pull rope 10 is positioned to prevent it from shifting during sliding. A placement groove 13 is provided on the front side of the connecting rod 3. A pull block 12 is fixedly connected to the end of the pull rope 10 away from the mounting plate 9. The pull block 12 is used to pull the two pull ropes 10 to move. The pull block 12 is slidably connected inside the placement groove 13, which provides installation space for the pull block 12. An elastic element 11 is sleeved on the outside of the pull rope 10. One end of the elastic element 11 is fixedly connected to the inner wall of the mounting groove 8, and the other end of the elastic element 11 is fixedly connected to the mounting plate 9.

[0026] When the locking block 7 needs to be pulled, the pulling block 12 is pulled forward, causing one end of the pulling rope 10 to move forward. This causes the other end of the pulling rope 10 to pull the mounting plate 9 to compress the elastic element 11, causing deformation. The mounting plate 9 then pulls the locking block 7 into the mounting groove 8. Conversely, by releasing the pulling block 12, the elastic element 11 is reset, which pushes the mounting plate 9 outward, allowing the mounting plate 9 to engage the locking block 7 with the inside of the groove 6.

[0027] Example 3: Based on Example 2, in order to improve the limiting effect of the limiting ring 4 and the extension ring 5 on the plug, a sliding groove 14 is provided inside the socket 2. The connecting rod 3 is slidably connected inside the sliding groove 14. The sliding groove 14 provides moving space for the connecting rod 3. A sliding piece 15 is fixedly connected to the rear end of the connecting rod 3. The sliding piece 15 is slidably connected inside the sliding groove 14. The sliding groove 14 limits the sliding piece 15 so that the sliding piece 15 will not deviate when sliding. An elastic element 2 16 is sleeved on the outside of the connecting rod 3. One end of the elastic element 2 16 is fixedly connected to the inner wall of the sliding groove 14, and the other end of the elastic element 2 16 is fixedly connected to the sliding piece 15.

[0028] When the limit ring 4 and extension ring 5 are used to limit the plug, the connecting rod 3 is pulled forward, which in turn causes the connecting rod 3 to drive the slider 15 to move forward. This causes the slider 15 to compress the elastic element 16 and deform, which in turn causes the elastic element 16 to perform a reset movement. This causes the elastic element 16 to drive the connecting rod 3 backward through the slider 15, which in turn causes the connecting rod 3 to drive the limit ring 4 backward through the locking block 7. Under the limitation of the extension ring 5, the limit ring 4 pulls the plug backward, thus stably limiting the plug.

[0029] The working process of this utility model is as follows:

[0030] After the transmission line plug is inserted into the socket 2, the corresponding limiting ring 4 is fitted onto the outside of the connecting rod 3. By pulling the pull block 12 forward, one end of the pull rope 10 is moved forward, causing the other end of the pull rope 10 to pull the mounting plate 9 to compress the elastic element 11, causing deformation. This allows the mounting plate 9 to pull the locking block 7 into the mounting groove 8, and the limiting ring 4 slides, so that the groove 6 and the locking block 7 are at the same horizontal position. Then, by releasing the pull block 12, the elastic element 11 returns to its original position, pushing the mounting plate 9 outward. This allows the mounting plate 9 to push the locking block 7 into the groove 6, thus limiting the limiting ring 4. Finally, by pulling the limiting ring 4, the extension ring 5 engages with the plug. The grooves fit together, and the limiting ring 4 pulls the connecting rod 3 forward, which in turn causes the connecting rod 3 to move the slide 15 forward. This causes the slide 15 to compress the elastic element 16 and deform it. At this time, the elastic element 16 can perform a reset movement, which allows the elastic element 16 to drive the connecting rod 3 backward through the slide 15. This allows the connecting rod 3 to drive the limiting ring 4 backward through the locking block 7. Under the limitation of the extension ring 5, the limiting ring 4 can pull the plug backward, so that the plug can be stably limited. After use, by replacing the limiting ring 4 on the connecting rod 3 with a blocking block, the blocking block can be inserted into the socket 2, and the locking block 7 can limit the blocking block, thereby reducing dust from entering the socket 2. This allows the connecting rod 3 and the locking block 7 to serve multiple purposes.
