Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a vehicle-mounted hydrogen fuel cell support. Background Technology

[0002] Hydrogen fuel cell vehicles represent a crucial development direction for new energy vehicles, and the safe securing of their onboard high-pressure hydrogen storage tanks or fuel cell tanks (hereinafter collectively referred to as "hydrogen fuel cell tanks") is of paramount importance. Traditional securing methods typically involve setting up independent securing mechanisms for each tank, which suffers from problems such as cumbersome structures, numerous components, and low assembly efficiency.

[0003] To address the aforementioned issues, improved solutions have emerged in the prior art. For example, Chinese Patent CN115072202A discloses a clamp structure for fixing a double-row cylindrical tank for vehicles. This solution cleverly employs an integrated clamp structure to simultaneously fix two parallel tanks. Compared to traditional solutions, it effectively simplifies the structure, reduces the number of parts, and improves assembly efficiency, representing a significant advancement.

[0004] However, this solution still has room for further optimization. The "main structure" supporting the bottom of the tank is a rigid structure integrally molded according to specific tank specifications. The drawback of this design is that when the diameter and curvature of the hydrogen fuel cell tank that needs to be secured change, the mounting base cannot perfectly fit the bottom surface of the tank, easily creating gaps between the tank and the support, resulting in insecure fixing and potential shaking, abnormal noise, or even safety risks during vehicle operation. To adapt to different tank models, manufacturers need to develop and stock various sizes of bottom molds, which undoubtedly increases production and warehousing costs and reduces the versatility of the support.

[0005] Therefore, this application provides a vehicle-mounted hydrogen fuel cell support to meet the requirements. Utility Model Content

[0006] The purpose of this application is to provide a vehicle-mounted hydrogen fuel cell support, which aims to solve the shortcomings of existing supports in terms of poor adaptability to tank specifications and low versatility, so as to achieve tight and reliable fixation of hydrogen fuel cell tanks with different diameters and curvatures.

[0007] To achieve the above objectives, this application provides the following technical solution: a vehicle-mounted hydrogen fuel cell support, comprising a support body and an upper fastening mechanism for fixing the hydrogen fuel cell tank. The support also includes an adaptively adjustable base plate assembly mounted on the support body for supporting the bottom surface of the hydrogen fuel cell tank.

[0008] The base plate assembly is one of the core innovations of this utility model. It includes multiple sets of independently movable sliding plates arranged side by side, the top surface of which is used to contact the bottom surface of the hydrogen fuel cell tank. Guide blocks are provided at both ends of the sliding plates. Side plates are provided on the front and rear sides of the support body, and each side plate has a guide groove adapted to the guide block to constrain and guide the movement of the guide block. In addition, a locking mechanism is provided to lock the relative position of all sliding plates after they have completed adaptive positioning.

[0009] Preferably, the locking mechanism includes at least one laterally arranged guide rod, a top plate that can slide along the guide rod, and a locking nut for locking the top plate onto the guide rod. This locking mechanism has a simple structure and provides reliable locking.

[0010] Preferably, the front and rear side plates are configured with unequal lengths. This unequal length design is key to achieving a clever locking mechanism. When the hydrogen fuel cell tank is placed on the base plate assembly, each sliding plate moves downwards under the tank's own weight, and the guide blocks at both ends protrude from under the shorter set of side plates. At this point, moving the top plate to press and tighten all the protruding guide blocks securely fixes the position of all sliding plates.

[0011] Preferably, the upper fastening mechanism includes a clamp, which is connected to the support body through a fixed bracket and a fixed seat to fasten the upper part of the tank.

[0012] Preferably, the top surface of the sliding plate is rounded to increase the contact area with the tank, disperse pressure, and protect the surface of the tank.

[0013] Preferably, the top surface of the base plate assembly is covered with a protective layer made of rubber or a soft polymer material to increase friction and further buffer vibration.

[0014] Preferably, the support body is composed of a robust support frame.

[0015] Preferably, the bracket further includes at least one adjusting positioning ring (9) slidably connected to the side plate (10) for providing initial guidance and positioning when installing the hydrogen fuel cell tank, facilitating the alignment of key parts such as the tank opening, and improving the ease of installation.

[0016] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the base plate assembly can automatically form a supporting arc surface that fits perfectly with the bottom surface of the tank according to the tank's own weight, thanks to the independently movable sliding plate. It can perfectly adapt to hydrogen fuel cell tanks of different diameters and curvatures without changing the mold, making it extremely versatile.

[0017] In this invention, the bottom plate assembly can achieve a "zero gap" fit with the bottom surface of the tank, eliminating the risk of shaking caused by mismatched specifications. Combined with the upper clamps for fastening, it achieves all-round stable fixation of the tank, greatly improving safety.

[0018] In this invention, the entire adaptive and locking process can be completed using the tank's own weight and a simple mechanical locking structure, making the operation intuitive and convenient and reducing the difficulty of installation.

[0019] In this invention, the added adjusting positioning ring provides initial guidance and support for the tank during installation, facilitating alignment with key interfaces, simplifying the installation process, and improving installation accuracy. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] refer to Figure 1-3 The illustrated vehicle-mounted hydrogen fuel cell support includes a support body 1 as a base, which is composed of a robust support frame 2.

[0025] As one implementation method in this embodiment, the core innovation of the bracket lies in its bottom plate assembly 3. This bottom plate assembly 3 is composed of multiple sliding plates 31 that can move independently up and down, arranged side by side. Each sliding plate 31 has guide blocks 32 integrally formed or fixedly connected to both ends.

[0026] In one embodiment of this invention, two side plates 10 are welded or bolted to the front and rear sides of the support frame 2. The heights of these two side plates 10 can be designed to be unequal. Each side plate 10 has multiple vertical or inclined guide grooves 33 corresponding to the number of sliding plates 31. The sliding plates 31 are embedded into the guide grooves 33 of the front and rear side plates 10 through guide blocks 32 at both ends, thereby achieving sliding only along the trajectory of the guide grooves 33.

[0027] As one embodiment of this invention, to facilitate the installation process of the hydrogen fuel cell tank, one or more adjusting positioning rings 9 are slidably connected to the shorter set of side plates 10. These adjusting positioning rings 9 can slide freely on the side plates 10 and be fixed at a specific height. Their upper surfaces can be designed as arc-shaped or have V-grooves to support and guide one end of the tank during installation. For example, the tank opening can be aligned and placed into the positioning ring to achieve initial axial and radial positioning.

[0028] In one embodiment of this invention, one or more guide rods 6 are laterally arranged below the shorter set of side plates 10. A top plate 8 is slidably connected to the guide rod 6. The top plate 8 can be locked and fixed at any position of the guide rod 6 by a locking nut 7.

[0029] As one embodiment of this invention, the upper fastening mechanism of the bracket consists of a hoop 11, a fixed bracket 4, and a fixed seat 5. Its structure and function are conventional technologies in the field, and it is used to bind and fix the hydrogen fuel cell tank from above.

[0030] The working principle of this practical system is as follows: When installing the hydrogen fuel cell tank, first adjust and fix the adjusting positioning ring 9 to a suitable height as needed. Then, align one end of the hydrogen fuel cell tank, such as the tank opening, with the adjusting positioning ring 9 to achieve initial positioning. Subsequently, loosen the locking nut 7 and move the top plate 8 to a position that does not interfere with the movement of the guide block 32. Next, smoothly lower the other end of the tank, allowing the entire tank to be placed completely above the base plate assembly 3. Under the weight of the tank itself, each sliding plate 31 in contact with the tank will slide downwards independently until its top surface is completely in contact with the curved surface of the tank bottom. At this point, the top surfaces of all sliding plates 31 together form a supporting arc surface that matches the bottom of the tank.

[0031] During the downward sliding process, the guide blocks 32 at both ends of the sliding plate 31 will slide downward along the guide grooves 33 on the two side plates 10. Since one side plate 10 is shorter, the guide block 32 will protrude from below the side plate 10.

[0032] After all the sliding plates 31 are in position, push the top plate 8 horizontally along the guide rod 6 so that it firmly presses against all the guide blocks 32 protruding from below the short side plate 10. This action will push all the guide blocks 32 against one side wall of their respective guide grooves 33, thereby using friction to firmly lock the position of all the sliding plates 31. Finally, tighten the locking nut 7 to completely fix the position of the top plate 8.

[0033] After securing the bottom, use the clamps 11 to tighten the top, thus completing the entire installation process.

[0034] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.

[0035] Components not described in detail in this article are existing technologies.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
