Shock-absorbing structure based on fuel cell stack supporting leg

Technical Field

The utility model relates to the technical field of fuel cells, in particular to a shock absorption structure based on a fuel cell stack support leg.

Background

After the fuel cell is produced, the finished product needs to be transported to various required industries through a set transportation route. However, in the transportation process of the fuel cell, the prior art does not consider the bearing capacity of the whole stack to the vibration impact in the vehicle-mounted environment, and if the stack encounters a large jolt or shake in the driving process, the stack is easily vibrated and deformed in the vehicle-mounted environment, and in a serious situation, even the risk of hydrogen leakage exists. In order to guarantee the reliability of the whole pile in the existing solution, the impact directly received by the pile in the transportation process is reduced by increasing the structural strength of the shell, but the weight of the pile is greatly improved due to the increase of the structural strength of the shell.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of vibration deformation or hydrogen leakage caused by insufficient bearing capacity of the whole stack to vibration impact in a vehicle-mounted environment in the prior art and provide a damping structure based on fuel cell stack support legs.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a shock-absorbing structure based on fuel cell pile stabilizer blade, includes pile body and unable adjustment base, unable adjustment base is equipped with a plurality of fixed slots, the pile body is equipped with a plurality of pile stabilizer blades, on the fixed shell of pile body was located to the one end of pile stabilizer blade, the other end was fixed in the fixed slot, be equipped with buffer spacer between pile stabilizer blade and the fixed slot.

The buffer pads wrap the side surfaces and the bottom surface of the pile support legs.

The buffer gasket is bonded on the inner side wall of the fixing groove.

A plurality of first fixing holes are formed in the pile support leg.

And a plurality of second fixing holes are formed in the fixing groove.

Further, the second fixing hole is formed in the bottom surface of the fixing groove.

Further, the number of the first fixing holes and the second fixing holes is the same.

Further, the first fixing hole and the second fixing hole have the same size.

The pile support leg and the fixing groove are fixed together through a bolt by a first fixing hole and a second fixing hole.

The fixed base further comprises a fixed plate, and the fixed groove is formed in the top surface of the fixed plate.

Furthermore, the bottom surface of the fixing plate is also provided with a buffer gasket.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the pile support legs are fixed in the fixing grooves of the fixing base, the buffer gaskets are arranged on the side surfaces and the bottom surfaces of the pile support legs for protection, and the buffer gaskets are also arranged on the bottom surface of the fixing plate of the fixing base, so that the intensity of impact vibration of a vehicle-mounted environment transmitted to the pile is effectively reduced through the buffer gaskets, the stability and the robustness of the pile under the vehicle-mounted environment are improved, and the intensity requirements of a pile shell and a reactor core are reduced.
