Description

Technical Field

[0001] The utility model relates to the technical field of fuel cell system vibration testing, in particular to a fuel cell system vibration tool. Background Art

[0002] A fuel cell system is a power generation system with a fuel cell at its core, and is composed of a fuel supply and circulation system, an oxidant supply system, a water / heat management system, and a control system. It is currently used as a power unit for vehicles.

[0003] Fuel cell systems are increasingly used in heavy-duty trucks. This is because fuel cell systems can operate stably in a variety of harsh conditions, such as high-altitude cold areas, mining areas, and humid and hot areas. Therefore, before leaving the factory, fuel cell systems need to undergo a series of reliability tests and verifications, usually using vibration tests to verify the reliability and durability of the product.

[0004] Generally, vibration testing requires the use of a vibration fixture to fix the fuel cell system. The vibration excitation is transmitted to the fuel cell system through the vibration fixture to simulate the vibration of the fuel cell system under different actual road conditions.

[0005] Since the vibration tooling needs to be designed according to the layout of the fuel cell system on the vehicle frame, and the layout plans of different systems are also different, it is generally necessary to separately design and verify the tooling for the installation plan of a certain fuel cell system, which is a relatively costly method. Utility Model Content

[0006] The purpose of the utility model is to provide a fuel cell system vibration tool to adapt to various types of fuel cell systems and reduce the detection cost of the fuel cell system.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A fuel cell system vibration tooling includes two symmetrically arranged tooling bodies, the tooling bodies including an upper tooling, a lower tooling and an adapter plate. The upper tooling is detachably connected to the top of the lower tooling. Two adapter plates are provided, and the two adapter plates are detachable from the top of the upper tooling or the top of the lower tooling.

[0009] Preferably, the upper tooling includes an upper I-beam and upper ribs, and a plurality of upper ribs are welded to both sides of the upper I-beam along the length direction.

[0010] Preferably, the lower tooling includes a lower I-beam and lower ribs, and a plurality of lower ribs are welded to both sides of the lower I-beam along the length direction.

[0013] Preferably, the bottom of the upper I-beam is detachably connected to the top of the lower I-beam via a fixing assembly, and the adapter plate is detachably connected to the top of the upper I-beam or the top of the lower I-beam via the fixing assembly.

[0015] Preferably, the tops of the upper I-beam and the lower I-beam are both provided with a plurality of fixing holes along the length direction.

[0016] Compared with the prior art, the fuel cell system vibration tooling of the present utility model has the following beneficial effects:

[0025] like Figures 1 to 4 As shown, the utility model relates to a fuel cell system vibration tooling, comprising two symmetrically arranged tooling bodies 1, wherein the tooling body 1 comprises an upper tooling 11, a lower tooling 12 and an adapter plate 13, wherein the upper tooling 11 is detachably connected to the top of the lower tooling 12, and two adapter plates 13 are provided, and the two adapter plates 13 are detachable from the top of the upper tooling 11 or the top of the lower tooling 12.

[0026] In the present invention, the fuel cell system vibration tooling adopts a double-layer design, and the adapter plate 13 is used to connect to the fuel cell system. The adapter plate 13 can be detachably connected to the top of the upper tooling 11, and can also be detachably connected to the top of the lower tooling 12. Then, when testing a high-power fuel cell system, the adapter plate 13 can be installed on the upper tooling 11. When testing a low-power fuel cell system, the upper tooling 11 can be removed from the top of the lower tooling 12, and the adapter plate 13 can be installed on the top of the lower tooling 12 for testing, so that the fuel cell system vibration tooling can be applicable to a variety of fuel cell systems, thereby improving applicability. At the same time, the adapter plate 13 can be detached from the top of the upper tooling 11 or the top of the lower tooling 12, so that the corresponding adapter plate 13 can be installed according to the installation position of different fuel cell systems, so as to further improve the applicability of the fuel cell system vibration tooling, and have higher compatibility, thereby helping to reduce the detection cost of the fuel cell system.

[0027] In this embodiment, the upper tooling 11 includes an upper I-beam 111 and an upper rib 112. A plurality of upper ribs 112 are welded on both sides of the upper I-beam 111 along the length direction, so that the upper tooling 11 has sufficient rigidity, light weight, and better stability to ensure smooth inspection. At the same time, it is easy to process and convenient to manufacture.

[0028] In this embodiment, the lower tooling 12 includes a lower I-beam 121 and a lower rib 122. A plurality of lower ribs 122 are welded on both sides of the lower I-beam 121 along the length direction, so that the lower tooling 12 has sufficient rigidity, light weight, and better stability to ensure smooth inspection. At the same time, it is easy to process and convenient to manufacture.

[0029] Preferably, the width of the top of the lower I-beam 121 is smaller than the width of the bottom of the lower I-beam 121 , and the side of the lower rib 122 away from the lower I-beam 121 gradually inclines toward the lower I-beam 121 from bottom to top.

[0030] Specifically, the top of the lower rib 122 and the side away from the lower I-beam 121 are flush with the side of the top of the lower I-beam 121, and the bottom of the lower rib 122 and the side away from the lower I-beam 121 are flush with the side of the bottom of the lower I-beam 121.

[0031] That is, the lower tooling 12 is trapezoidal, so that the lower tooling 12 is more stable and has a stronger supporting strength to ensure smooth detection.

[0032] In this embodiment, the bottom of the upper I-beam 111 is detachably connected to the top of the lower I-beam 121 through a fixing assembly, and the adapter plate 13 is detachably connected to the top of the upper I-beam 111 or the top of the lower I-beam 121 through the fixing assembly.

[0033] Specifically, the fixing assembly includes a fixing bolt and a fixing nut, and the tops of the upper I-beam 111 and the lower I-beam 121 are both provided with fixing holes 2 for the fixing bolts to enter.

[0034] By using fixing bolts and fixing nuts, the adapter plate 13 can be conveniently fixed to the upper tooling 11 or the lower tooling 12 and is easy to disassemble, while also ensuring the stability of the connection to ensure smooth detection.

[0035] Preferably, the tops of the upper I-beam 111 and the lower I-beam 121 are provided with a plurality of fixing holes 2 along the length direction, so that the adapter plate 13 can be installed to a specific position of the upper tooling 11 or the lower tooling 12 according to the installation position of the fuel cell system, so as to improve the applicability and compatibility of the vibration tooling of the fuel cell system.

[0036] Alternatively, the tops of the upper I-beam 111 and the lower I-beam 121 can be used to select the positions of the fixing holes 2 according to the actual installation position of the fuel cell system to meet the installation requirements of the fuel cell system.

[0037] In summary, compared with the existing technology, the fuel cell system vibration tooling of the present application has a simpler structure and better structural stability, and can adapt to the detection of fuel cell systems of various models and powers, thereby reducing the equipment cost required for detection.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
