[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 and 2As shown, a fuel cell follower clamping device of the present invention includes an assembly plate 1, a follower clamping mechanism 2, a fixed clamping mechanism 3, and an elastic component 4. The fixed clamping mechanism 3 includes two fixed clamping components 31 and a fixed plate 32. The fixed plate 32 is fixedly mounted on the assembly plate 1 and located at one end thereof. The two fixed clamping components 31 are respectively disposed on both sides of the fixed plate 32 and move toward each other to clamp the fuel cell or away from each other to loosen the fuel cell.

[0023] The follower clamping mechanism 2 includes two follower clamping assemblies 21 and a follower plate 22. The follower plate 22 is slidably disposed on the assembly plate 1 and is located at the other end thereof to slide away from or toward the fixed plate 32. The follower plate 22 is positioned at any position along its sliding trajectory by a first locking member 23. The two follower clamping assemblies 21 are respectively disposed on either side of the follower plate 22 and move toward each other to clamp or release the fuel cell.

[0024] The follower clamping assembly 21 includes a first clamping seat 211, a first clamping plate 212, and a second locking member 213. The first clamping seat 211 is disposed on one side of the follower plate 22. The first clamping plate 212 is slidably disposed on the first clamping seat 211 and slides in a direction toward or away from the fixed clamping assembly 31. The second locking member 213 positions the first clamping plate 212 at any position along its sliding trajectory.

[0025] The elastic component 4 includes a first elastic member 41 and two second elastic members 42. The first elastic member 41 is squeezed between the follower plate 22 and the fixed plate 32. The two second elastic members 42 are respectively squeezed between the first clamping plate 212 and the fixed clamping component 31 located on both sides of the assembly plate 1.

[0026] The operation process of a fuel cell follower clamping device of the present invention is as follows: the stationary part of the fuel cell during the assembly process is positioned on the fixed plate 32 by using two fixed clamping assemblies 31; the moving part of the fuel cell during the assembly process is positioned on the follower plate 22 by using the first clamping plates 212 of the two follower clamping assemblies 21. During the assembly process, the fuel cell is subjected to a force applied from the other end of the assembly plate 1 to one end thereof. At this time, the first clamping plate 212 and the follower plate 22 move along the assembly plate 1 toward the fixed plate 32 along with the moving part of the fuel cell. After the assembly is completed, the follower plate 22 is limited by the first locking member 23, and the first clamping plate 212 is limited by the second locking member 213. The position of the fuel cell is fixed and maintained in a compressed state, and the fuel cell is assembled. After the assembly is completed, the first locking member 23 and the second locking member 213 are reset, the elastic member 4 is extended, the follower plate 22 and the first clamping member are reset, and the next fuel cell is installed. In this way, relative movement is avoided to wear the fuel cell surface, and the fuel cell installation consistency is good and the qualified rate is high.

[0027] The two fixed clamping assemblies 31 are respectively arranged on both sides of the fixed plate 32, and move closer to each other to clamp the fuel cell or move away from each other to release the fuel cell. There are many ways to set the two fixed clamping assemblies 31, which are not limited here. The two follower clamping assemblies 21 are respectively arranged on both sides of the follower plate 22, and move closer to each other to clamp the fuel cell or move away from each other to release the fuel cell. There are many ways to set the two follower clamping assemblies 21, which are not limited here. In this embodiment, the clamping device can also include two slides 5 and a driving mechanism 6. The two slides 5 are respectively arranged below the assembly plate 1 at intervals, and the slides 5 are parallel to the assembly plate 1. The two fixed clamping assemblies 31 are respectively fixed at one end of the two slides 5, and the two first clamping seats 211 are respectively fixed at the other end of the two slides 5. The driving mechanism 6 is connected to the two slides 5 in a transmission manner to drive the two slides 5 to move closer to or away from each other. In this way, the driving mechanism 6 can simultaneously realize the movement of the two slides 5 to realize the two fixed clamping assemblies 31 and the two follower clamping assemblies 21 moving closer to each other to clamp the fuel cell or move away from each other to release the fuel cell.

[0028] There are many ways to set up the two slides 5. In this embodiment, the lower surface of the assembly plate 1 can be fixedly provided with two guide rails 11 in parallel. The extension direction of the two guide rails 11 is parallel to the movement direction of the slide 5. The two ends of the two slides 5 are respectively slidably provided on the two guide rails 11, and the driving mechanism 6 drives the two slides 5 to move along the guide rails 11.

[0029] There are various structures of the driving mechanism 6, which are not limited here. In this embodiment, the driving mechanism 6 may include two cylinders 61, and two mounting seats 12 are fixedly provided on the lower plate surface of the assembly plate 1, and the two mounting seats 12 are located between the two slides 5. The two cylinders 61 are respectively fixed on the two slides 5, and the driving ends of the two cylinders 61 are fixedly provided on the two mounting seats 12 in a one-to-one correspondence. The two cylinders 61 simultaneously drive the two slides 5 to move closer to or away from each other, so that the two fixed clamping assemblies 31 and the two follower clamping assemblies 21 move closer to each other to clamp the fuel cell or move away to loosen the fuel cell.

[0030] There are various ways to slidably mount the first clamping plate 212 on the first clamping seat 211, which are not limited herein. In this embodiment, a first guide rail 214 can be provided on one side of the first clamping plate 212 and extends along the direction of movement of the first clamping plate 212. The first guide rail 214 can be slidably mounted on the first clamping seat 211. The second locking member 213 includes a first guide rail lock 2131 fixedly mounted on the first clamping seat 211. The first guide rail 214 can be slidably mounted on the first guide rail lock 2131. The first guide rail lock 2131 can be a commercially available product, such as the domestically produced HTPM guide rail lock CPS45S.

[0031] There are various structures of the second elastic member 42, which are not limited here. In this embodiment, the second elastic member 42 may include a second gas spring 421, one end of the second gas spring 421 is connected to the fixed clamping assembly 31, and the other end of the second gas spring 421 is connected to the first clamping plate 212. The two first clamping plates 212 and the follower plate 22 clamp the fuel cell together. When external force is applied to make the fuel cell move toward the fixed plate 32, the two first clamping plates 212 and the follower plate 22 follow the fuel cell, so that the second gas spring 421 is compressed. After the external force is withdrawn, the two first clamping plates 212 are reset under the action of the reset force of the second gas spring 421.

[0032] There are many ways to slide the follower plate 22 on the assembly plate 1. In this embodiment, a second guide rail 24 can be provided on one side of the follower plate 22 and extended along the movement direction of the follower plate 22. The second guide rail 24 can be slidably set on the assembly plate 1.

[0033] The structure of the first locking member 23 can be determined based on how the follower plate 22 is specifically mounted on the assembly plate 1. In this embodiment, the first locking member 23 can include two second guide rail locks 231 spaced apart along the direction of movement of the follower plate 22. The second guide rail 24 is slidably mounted on the two second guide rail locks 231. The second guide rail locks 231 can be commercially available, such as the domestically produced HTPM guide rail lock CPS45S.

[0034] Two fixing platforms 13 can also be provided on the assembly plate 1, and the two fixing platforms 13 are respectively arranged on both sides of the follower plate 22. A third elastic member 7 is provided between the two fixing platforms 13 and the two first clamping seats 211 or\ and the second clamping seats 311. In this way, when the two follower clamping assemblies and the two fixed clamping assemblies 31 move closer to each other to clamp the fuel cell or move away from each other to release the fuel cell, the third elastic member 7 can play a buffering role, so that when the follower clamping assembly and the two fixed clamping assemblies come into contact with the fuel cell, damage to the fuel cell is avoided.
