[0002] With the rapid development of new energy technologies, especially fuel cell technology, the performance of the fuel cell stack, a core component of the fuel cell, directly impacts the efficiency and reliability of the entire system. A fuel cell stack consists of multiple cells connected in series or parallel, generating electricity through chemical reactions. To ensure close contact between components within the stack and maintain its stability and safety during operation, a specially designed limit clamp is required to secure the stack.

[0003] At present, traditional stack limit fixtures often have the following technical problems:

[0004] For battery stacks designed for specific sizes and shapes, when the specifications of the battery stack change, the original fixture may not be applicable, resulting in the need to redesign and manufacture new fixtures, increasing costs and time.

[0005] Poor adaptability: Due to the different requirements of fuel cell stacks in different application scenarios, such as power density, operating temperature, etc., existing limit clamps are difficult to meet diverse needs, especially when handling fuel cell stacks of non-standard sizes or special shapes.

[0006] High installation complexity: The design of some limit clamps is relatively complex and the installation process is cumbersome, which not only increases the difficulty of assembly but may also affect the overall performance of the fuel cell stack.

[0028] Please refer to Figure 1-3 , Figure 1 The figure shows a schematic diagram of the structure of the embodiment of the utility model when it is fully unfolded; Figure 2 The figure shows the structure of the embodiment of the utility model when it is fully folded. Figure 3 Shown is a top view of the base in an embodiment of the present utility model.

[0029] An embodiment of the present utility model provides a battery stack limiting clamp, comprising a base; a plurality of guide rails, any of which is provided in the base; a plurality of limiting posts, any of which corresponds to the guide rails one-to-one, and any of which is slidably connected to the guide rails; a plurality of fixing bolts, located on both sides of any of which, any of which is rotatably connected to the bottom of its corresponding limiting post; fixing holes, provided on both sides of any of which, a plurality of fixing holes are provided on both sides of any of which, the fixing holes correspond to the fixing bolts one-to-one. The utility model adjusts the limiting posts to slide freely on the guide rails of the base to adapt to the battery stack to be clamped. After the plurality of limiting posts clamp the battery stack, the fixing bolts are screwed into the corresponding fixing holes to complete the fixation.

[0030] In some embodiments of the present invention, the base is cross-shaped, and the plurality of guide rails are arranged in a cross shape and are respectively located within the cross edges of the base. The cross shape fixes the battery stack from four directions, thereby making the battery stack more stable.

[0031] In some embodiments of the present invention, any of the above-mentioned limiting posts are perpendicular to the base. The perpendicularity of the limiting posts to the base can ensure that the limiting posts are in full contact with the battery stack, thereby avoiding the formation of gaps that may cause unstable clamping of the battery stack.

[0032] In some embodiments of the present invention, the retaining posts are provided with clamping grooves oriented toward the center of the base. These grooves provide a more stable grip on the battery stack, preventing it from tilting and causing collapse or instability. In this embodiment, the battery stack is secured by the clamping grooves on a pair of opposing retaining posts. Alternatively, two or more pairs of retaining posts may be provided with clamping grooves to further stabilize the battery stack.

[0033] In some embodiments of the present invention, an operating plate is provided on each of the aforementioned limiting posts, the operating plate being fixedly connected to the limiting post and facing outward from the base. The operating plate allows an operator to more conveniently operate the limiting post within the guide rail. Specifically, the operator grasps the operating plate to push or pull the limiting post, thereby improving the stability of the limiting post's sliding within the guide rail.

[0034] In some embodiments of the present invention, the base is provided with a fixing hole for fixing the base, through which the entire device can be fixed in a specific position, thereby making it easier to fix and limit the position of the battery stack.

[0035] In summary, the embodiments of the present invention provide a battery stack limiting clamp, which can not only be adjusted arbitrarily according to battery stacks of different sizes or sizes, thereby playing the role of all-round limiting the battery stack, greatly improving the applicability of the device, but also the overall structure of the device is very simple and easy to assemble, which is conducive to carrying and operation by operators anytime and anywhere, thereby improving convenience.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
