Description

Technical Field

[0001] This utility model belongs to the field of fuel cell mounting technology, and specifically relates to a mounting for a hydrogen fuel cell engine. Background Technology

[0002] With the booming development of the hydrogen energy industry, the product research and development and commercial application of hydrogen fuel cell vehicles are progressing rapidly. As a core power component, the stability and reliability of the hydrogen fuel cell engine's installation are crucial. The mounting mount is a key component connecting the engine to the vehicle frame, used for shock absorption and support.

[0003] In existing technologies, the mounting structures of hydrogen fuel cell engines have some shortcomings. First, commercially available fuel cell mounting structures are generally complex, have limited functionality, and lack unified industry standards, making them difficult to adapt to different vehicle models. Second, existing mounting structures are typically large in size, have low integration, and rarely consider providing mounting support for peripheral engine piping (such as exhaust pipes and cooling pipes), resulting in the need for additional brackets to fix the piping, increasing the number of parts and installation complexity. Utility Model Content

[0004] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a mounting bracket for hydrogen fuel cell engines. This invention features a simpler structure, higher integration, and easier installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] This utility model provides a suspension for a hydrogen fuel cell engine, characterized in that it includes a suspension body, a lifting lug, a suspension fixing bolt, an upper suspension bracket, a suspension pad, a lower suspension bracket, a suspension support bolt, and a pipeline bracket. The lifting lug is fixedly connected to the upper end of the suspension body. The suspension fixing bolt passes through a bolt hole on the side of the suspension body for connection to the fuel cell engine housing. The suspension pad is filled and sandwiched between the upper suspension bracket and the lower suspension bracket. The upper suspension bracket, the suspension pad, and the lower suspension bracket are all connected to the other side of the suspension body via a vertically arranged suspension support bolt. The suspension body can be connected to the upper support point of the fuel cell engine mounting bracket via the suspension support bolt. The pipeline bracket is detachably connected to the lower end of the suspension body via a fixing bolt.

[0007] Furthermore, the suspension pad is a single, integrally molded rubber pad.

[0008] Furthermore, the pipe support is L-shaped.

[0009] Furthermore, the length of the pipe support corresponds to the distance between the lower end of the vehicle's exhaust pipe or water pump pipe and the distance between the suspension body and the fuel cell engine housing, and is used to support the exhaust pipe or water pump pipe.

[0010] Furthermore, the suspension body has a mounting surface for connection with the fuel cell engine housing.

[0011] Furthermore, the lifting lug has a plate-like structure, the lower end of the lifting lug is connected to the suspension body, and the upper end of the lifting lug has a lifting hole.

[0012] The beneficial effects of this utility model.

[0013] This invention combines the suspension body with the lifting lug, simplifying the suspension structure. Employing a single suspension pad structure simplifies the structure, reduces weight, and facilitates installation while ensuring the filtering of vertical engine vibrations from the vehicle body. By integrating detachable pipe supports of different sizes, it can support exhaust pipes and water pump pipes separately, increasing the suspension's ability to support both. The interface between the suspension structure and the fuel cell engine housing is located vertically on the side of the fuel cell engine housing, and the mounting point at the lower end of the suspension can connect to the fuel cell engine mounting bracket, increasing integration.

Detailed Implementation

[0022] As shown in the accompanying drawings, this embodiment provides a suspension for a hydrogen fuel cell engine, including a suspension body 1, a lug 2, a suspension fixing bolt 3, an upper suspension bracket 4, a suspension pad 5, a lower suspension bracket 6, a suspension support bolt 7, and a pipeline bracket 8.

[0023] The lifting lug 2 is a plate-shaped structure. The upper end of the lifting lug 2 has a lifting hole, and the lower end is fixedly connected to the upper end of the suspension body 1 (by welding or other fixing methods).

[0024] The suspension body 1 serves as the core load-bearing component. One side has a mounting surface for connecting with the fuel cell engine housing 9. The suspension fixing bolt 3 passes through the bolt hole on the side of the suspension body 1 to connect the suspension body 1 to the side of the fuel cell engine housing 9.

[0025] The suspension pad 5 is sandwiched between the upper suspension bracket 4 and the lower suspension bracket 6. The upper suspension bracket 4, suspension pad 5, and lower suspension bracket 6 are connected to the other side of the suspension body 1 via vertically arranged suspension support bolts 7. Specifically, the suspension support bolts 7 pass sequentially through the through hole of the upper suspension bracket 4, the center hole of the suspension pad 5, and the through hole of the lower suspension bracket 6, and are locked to the threaded hole (or by a nut) on the suspension body 1, thereby fixing all three to the suspension body 1. The suspension pad 5 is a single, integrally molded rubber pad, serving as a shock-absorbing element to filter vertical vibrations from the vehicle body. The suspension body 1 can be connected to the upper support point of the fuel cell engine mounting bracket 10 via the suspension support bolts 7.

[0026] The pipe support 8 is detachably connected to the lower end of the suspension body 1 by fixing bolts. The pipe support 8 is L-shaped. The length of the pipe support 8 corresponds to the distance between the lower end of the vehicle's exhaust pipe 11 or water pump pipe 12 and the distance between the suspension body 1 and the fuel cell engine housing 9, and is used to support the exhaust pipe 11 or water pump pipe 12.

[0027] Working principle: During installation, the suspension body 1 is fixed to the side of the fuel cell engine housing 9 by the suspension fixing bolts 3. When the vibration of the engine and the vibration from the vehicle body are transmitted to the suspension structure, the suspension pads 5 undergo elastic deformation, consuming vibration energy, thereby playing a role in shock absorption and engine stabilization. At the same time, the integrated pipe supports 8 provide stable support for the corresponding exhaust pipes 11 and water pump pipes 12.

[0028] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
