The hydrogen storage cylinder 3 is used for storing hydrogen. The first valve 10 controls the connection between the hydrogen storage cylinder 3 and an external hydrogen filling tank, enabling the opening and closing of the hydrogen filling process. When hydrogen filling is needed, the first valve 10 is opened to allow hydrogen to enter the hydrogen storage cylinder. When hydrogen filling is complete or not needed, the first valve 10 is closed to prevent further hydrogen inflow, ensuring the operability and safety of the hydrogen filling process. In use, the first valve 10 and the second valve 11 located on the external hydrogen filling tank are opened, connecting the first valve 10 and the second valve 11, thus connecting the cylindrical body 1 to the external hydrogen filling tank for hydrogen filling.

The enhanced nylon damping layer made of soft wear-resistant PA66 material is arranged at the position of the cylinder body 1 in contact with the hydrogen storage bottle 3, which can effectively increase the friction between the hydrogen storage bottle 3 and the cylinder body 1, make the connection between the hydrogen storage bottle 3 and the cylinder body 1 more closely, and reduce the risk of the hydrogen storage bottle 3 falling off from the cylinder body 1.

[0155] As shown in the figure, Figure 5 The first sensor 13 is located at one end of the cylinder body 1 close to the cover body 2, and the second sensor 14 is located at one end of the cylinder body 1 close to the bottom of the hydrogen storage bottle 3. The first sensor 13 detects whether the hydrogen storage bottle 3 enters the cylinder body 1, and the second sensor 14 detects whether the hydrogen storage bottle 3 has reached the position of normal hydrogen filling in the cylinder body 1, so as to ensure that the first valve body 10 and the second valve body 11 can be better connected, and the sealing effect of the hydrogen filling assembly as a whole is improved.

[0156] The distance from the position of the first sensor 13 in the cylinder body 1 to the end face of the cylinder body 1 away from the cover body 2 is 75% of the length of the hydrogen storage bottle 3.

[0157] The specific use mode of the hydrogen filling assembly of the utility model is as follows:

[0158] When hydrogen needs to be filled, the cylinder 1 is communicated with the external hydrogen filling tank, the first sensor 13 detects whether the hydrogen storage bottle 3 enters the cylinder 1, the second sensor 14 detects whether the hydrogen storage bottle 3 has reached the normal hydrogen filling position inside the cylinder 1, if the first sensor 13 and the second sensor 14 monitor the normal state, press the button 9 to drive the connecting rod 7 to control the rotation of the shifting block 8, so that the first valve body 10 and the second valve body 11 are communicated, and the hydrogen filling is started. The first sensor 13 and the second sensor 14 work in real time during the hydrogen filling process, monitor whether the position of the hydrogen storage bottle 3 is normal, ensure the stability of the hydrogen filling work, and further ensure the smooth progress of the hydrogen filling of the hydrogen storage bottle 3. The pressure sensor 15 feeds back the hydrogen filling pressure of the external hydrogen filling tank in real time, when the hydrogen filling pressure of the external hydrogen filling tank is low, the hydrogen storage bottle 3 can be taken out, the pressure sensor 15 is set to ensure that the hydrogen filling pressure of the external hydrogen filling tank is in a high state, which is more conducive to safely filling the hydrogen storage bottle 3 with hydrogen. After the hydrogen filling is completed, the cylinder 1 can be manually operated to separate from the external hydrogen filling tank, press the button 9 to drive the connecting rod 7 to control the action of the shifting block 8, so that the first valve body 10 and the second valve body 11 which are locked are separated, and the hydrogen storage bottle 3 can be pulled out.
