Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a fuel cell stack installation fixture. Background Art

[0002] Solid oxide fuel cells (SOFCs) hold a crucial position in the energy conversion field due to their high efficiency and environmentally friendly characteristics. As the core component of a SOFC system, the safety and efficiency of its installation and handling directly impact the overall system performance. To meet this demand, the industry has developed a variety of tools for SOFC stack handling and installation, and several utility model patents have been granted.

[0003] Utility model patent CN214359704U describes a stack handling device based on a bottom bracket platform design. This device utilizes fixed pull rods on both sides and a top hoisting assembly to handle the stack. While this structure provides good support and stability for the stack, it suffers from inflexible handling and low clamping efficiency in actual operation, limiting work efficiency.

[0004] Utility model patent CN209256370U provides a method for quickly clamping a fuel cell stack using multiple clamping mechanisms located at the top. However, this solution only works with fuel cell stacks equipped with specialized lifting devices for handling. For bare fuel cell stacks without these accessories, additional support devices for clamping from below are required for handling, significantly reducing the tool's versatility and convenience.

[0005] Utility model patent CN215988870U describes a battery stack fixture consisting of six tie rods and a bottom bracket. While this design enhances overall structural strength, its complex construction and lack of automatic positioning require the use of auxiliary equipment or manual positioning before placing the battery stack on the fixture, increasing operational difficulty and reducing cost-effectiveness.

[0006] Utility model patent CN212043602U describes a clamping device designed for battery stacks with a top lifting port. It optimizes the top structure to effectively grasp and move these types of battery stacks. However, this method is also inapplicable to ordinary bare battery stacks without pre-set lifting points, further exposing the limitations of current solutions when dealing with different types of battery stacks.

[0033] See also Figure 1-Figure 3 , this embodiment provides a battery stack installation fixture, including: a first clamping arm 1, a second clamping arm 2, a rotating shaft 3 and a fastener 4. The first clamping arm 1 and the second clamping arm 2 are arranged relative to each other to form a clamping space 6 for placing the battery stack 5. One end of the first clamping arm 1 and one end of the second clamping arm 2 are rotatably connected through the rotating shaft 3 to increase or decrease the clamping space 6. The other end of the first clamping arm 1 and the other end of the second clamping arm 2 are both provided with a clamping piece 7 for clamping the battery stack 5; the two ends of the fastener 4 are respectively connected to one end of the first clamping arm 1 and one end of the second clamping arm 2 to achieve fixed locking of the first clamping arm 1 and the second clamping arm 2.

[0034] This embodiment provides a first clamping arm 1 and a second clamping arm 2, and provides a clamping piece 7 for clamping the battery stack 5 on the first clamping arm 1 and the second clamping arm 2, thereby realizing free clamping and transportation of the battery stack 5. It has a simple structure and is easy to manufacture and maintain, and is easy to operate, which improves the efficiency of clamping and transportation. It does not require additional hanging parts or lifting points, has strong versatility, and adopts an adjustable design. The clamp can adapt to battery stacks 5 of different specifications, increasing its wide range of use.

[0035] Its working principle is as follows: the first clamping arm 1 and the second clamping arm 2 are arranged relative to each other to form a space that can accommodate the battery stack 5. The first clamping arm 1 and the second clamping arm 2 are connected by a rotating shaft 3, so that the first clamping arm 1 and the second clamping arm 2 can rotate freely at the rotating shaft 3, thereby changing the size of the clamping space 6. When it is necessary to clamp the battery stack 5, the first clamping arm 1 and the second clamping arm 2 are opened to expand the clamping space 6 and place the battery stack 5 therein; then the clamping space 6 is reduced by closing the clamping arms until the clamping member 7 penetrates the concave installation and transportation hole at the bottom of the battery stack 5 and clamps the battery stack 5. Finally, the position of the two clamping arms is locked using the fastener 4 to ensure that the battery stack 5 is firmly fixed in the fixture, thereby completing the clamping of the battery stack 5. After the battery stack 5 is transported to the installation position, when the battery stack 5 needs to be removed, the fastener 4 is opened to release the lock on the two clamping arms, and then the first clamping arm 1 and the second clamping arm 2 are opened to remove the battery stack mounting fixture from the battery stack 5.

[0036] In this embodiment, please refer to Figure 4-Figure 6 The fastener 4 is a fastening screw, a through hole 8 is provided on the first clamping arm 1, and a threaded hole 9 is provided on the second clamping arm 2. One end of the fastening screw passes through the through hole 8 and is threadedly connected to the threaded hole 9 to achieve fixed locking of the first clamping arm 1 and the second clamping arm 2, and a limiting portion 10 is provided at the other end of the fastening screw.

[0037] When the battery stack 5 needs to be clamped, the first clamping arm 1 and the second clamping arm 2 can rotate relative to each other via the rotating shaft 3 to adjust the size of the clamping space 6. Once the battery stack 5 is placed between the two clamping arms and adjusted to the appropriate position, one end of the fastening screw passes through the through hole 8 in the first clamping arm 1 and is threadedly connected to the threaded hole 9 in the second clamping arm 2. The fastening screw is rotated to tighten the two clamping arms, thereby firmly fixing the battery stack 5.

[0038] By utilizing the mechanical locking effect provided by the fastening screws, the stack 5 can be kept stable during transportation and not easily slip or fall off. Secondly, compared with the traditional multi-step installation method, direct clamping and simple screw fastening significantly shortens the operation time.

[0039] The limiting portion 10 can be either a unidirectional or bidirectional restriction. There are two types of unidirectional restrictions: one that can restrict the movement of the fastening screw and the second clamping arm 2 in the direction of increasing the clamping space 6, but does not restrict the movement of the fastening screw and the second clamping arm 2 in the direction of reducing the clamping space 6. In this case, the limiting portion 10 can be a protrusion located on the outside of the first clamping arm 1, and the size of the protrusion is larger than the diameter of the through hole 8. The other type does not restrict the movement of the fastening screw and the second clamping arm 2 in the direction of increasing the clamping space 6, but restricts the movement of the fastening screw and the second clamping arm 2 in the direction of reducing the clamping space 6. In this case, the limiting portion 10 can be a component such as a nut located on the inside of the first clamping arm 1. Bidirectional restriction not only restricts the movement of the fastening screw and the second clamping arm 2 in the direction of increasing the clamping space 6, but also restricts the movement of the fastening screw and the second clamping arm 2 in the direction of reducing the clamping space 6. In this case, the limiting portion 10 includes a protrusion and a nut, with the protrusion located on the outside of the first clamping arm 1 and the nut located on the inside of the first clamping arm 1.

[0040] It should be noted that, taking the example of one end of the first clamping arm 1 being located above one end of the second clamping arm 2, when a user grips one end of the first clamping arm 1 for transport, a design can be employed that restricts the movement of the fastening screw and second clamping arm 2 toward increasing the clamping space 6, but does not restrict movement toward decreasing the clamping space 6. When a user grips one end of the second clamping arm 2 for transport, a design can be employed that does not restrict movement toward increasing the clamping space 6, but restricts movement toward decreasing the clamping space 6. A bidirectional restriction design does not require consideration of the user's gripping position during transport.

[0041] In this embodiment, the rotating shaft 3 is perpendicular to the fastening screw.

[0042] Specifically, taking the axis of the rotating shaft 3 as an example, which faces the screen, the direction of the fastening screw can be vertical or horizontal. This ensures that after the first clamping arm 1 and the second clamping arm 2 rotate via the rotating shaft 3, the fastening screw can pass through the first clamping arm 1 and connect with the threaded hole 9 on the second clamping arm 2 to achieve locking of the first clamping arm 1 and the second clamping arm 2.

[0043] In this embodiment, the through hole 8 is a long strip-shaped through hole.

[0044] When the clamping space 6 between the first clamping arm 1 and the second clamping arm 2 changes, the fastening screw, threadedly connected to the threaded hole 9 on the second clamping arm 2, needs to continuously adjust its tilt to adapt to the change in the clamping space 6. The design of the elongated through-hole allows the fastening screw to move within a certain range, meeting the need for continuous adjustment of the fastening screw's tilt. This allows the battery stack mounting fixture to adapt to battery stacks 5 of different widths, improving its versatility.

[0045] In some embodiments, the fastener 4 is a fastening screw, a threaded hole 9 is provided on the first clamping arm 1, and a threaded hole 9 is provided on the second clamping arm 2. The fastening screw is threadedly connected to the two threaded holes 9 to achieve fixed locking of the first clamping arm 1 and the second clamping arm 2.

[0046] This structure primarily achieves secure locking through a fastening screw and two clamping arms with threaded holes 9. This design makes the entire structure relatively simple, eliminating the need for complex assembly. During operation, simply thread the fastening screw into the threaded holes 9 of the two clamping arms and tighten by rotating the fastening screw, making it easy and quick to operate. The threaded connection between the fastening screw and the threaded holes 9 generates a high friction force, ensuring a secure connection between the two clamping arms.

[0047] Furthermore, a plurality of threaded holes 9 can be provided on the first clamping arm 1 and the second clamping arm 2 , and fastening screws can be screwed into different threaded holes 9 to meet the changing requirements of the clamping space 6 between the first clamping arm 1 and the second clamping arm 2 .

[0048] In this embodiment, the other end of the fastening screw is provided with a rotating portion 11 (such as Figure 6 The rotating portion 11 may be a bump, a texture, or another structure that enables rapid rotation of the fastening screw. The provision of the rotating portion 11 allows the fastening screw to be easily tightened and removed through a rotating action, greatly simplifying the operation process and improving work efficiency compared to traditional manual or tool-assisted methods.

[0049] In this embodiment, a U-shaped portion 13 having a U-shaped opening 12 is provided at one end of the first clamping arm 1 (eg Figure 4 As shown), the U-shaped portion 13 is located at the top of the second clamp arm 2 and the U-shaped opening 12 faces the second clamp arm 2, and the U-shaped portion 13 and one end of the second clamp arm 2 enclose a gripping area 14 (as shown Figure 2 shown).

[0050] The U-shaped portion 13 of the first clamping arm 1 and one end of the second clamping arm 2 form a gripping area 14. This design provides the user with a stable and comfortable gripping point, allowing the hand to more firmly grasp the entire device during operation, reducing the risk of slipping or loss of control.

[0051] Furthermore, the gripping area 14 may be provided with anti-slip patterns or coated with anti-slip materials (such as rubber or silicone). The presence of anti-slip patterns or materials can significantly increase the friction between the hand and the gripping area 14, preventing slippage caused by sweaty, wet hands, or improper force during operation. This not only improves operational stability but also ensures safe use.

[0052] In this embodiment, the rotating shaft 3 and the fastener 4 are respectively located on two sides of the gripping area 14 .

[0053] The shaft 3 and fastener 4 are located on either side of the grip area 14, providing the user with more ample operating space. This layout prevents collision or interference between the hand and the shaft 3 or fastener 4 during operation, making operation smoother and more natural. Placing the shaft 3 and fastener 4 on either side of the grip area 14 helps distribute stress when the device is subjected to force, improving the overall stability of the structure. This design makes the device more durable even under heavy loads.

[0054] In this embodiment, the clamping space 6 is at least 3 mm larger than the outer dimensions of the battery stack 5. That is, the distance between the inner sides of the first and second clamping arms 1 and 2 and the outer surface of the battery stack 5 is at least 3 mm. This prevents pressure on the battery stack 5 when clamping, thereby protecting the battery stack 5.

[0055] In this embodiment, the assembly also includes: a positioning member 15 (such as Figure 3 As shown), the assembly positioning member 15 is installed at the other end of the first clamping arm 1 and / or the other end of the second clamping arm 2 to cooperate with the bottom of the battery stack 5.

[0056] The design of the assembly locator 15 enables the clamping arm to more precisely position and secure the battery stack 5. By engaging with the bottom of the battery stack 5, the stability and accuracy of the battery stack 5 during handling are ensured. The assembly locator 15 simplifies the assembly process and makes it more convenient. Workers can quickly align and secure the battery stack 5 with the clamping arm without tedious adjustments and calibration, thereby improving assembly efficiency.

[0057] In some embodiments, a bottom support plate 16 (such as Figure 7 As shown), the assembly positioning member 15 cooperates with the bottom support plate 16 to achieve rapid positioning and cooperation of the battery stack 5.

[0058] In this embodiment, the assembly positioning member 15 is L-shaped.

[0059] The L-shaped assembly positioning member 15 is designed to more accurately position the stack 5 or other components to be assembled. Its right-angled shape provides a stable support surface, helping to prevent displacement or tilting during assembly and transportation, ensuring accuracy and stability during assembly and transportation.

[0060] In this embodiment, please refer to Figure 2 The other end of the first clamping arm 1 is provided with at least one first limiting member 17 for limiting the shaking of the battery stack 5, and the other end of the second clamping arm 2 is provided with at least one second limiting member 18 for limiting the shaking of the battery stack 5.

[0061] The first limiter 17 and the second limiter 18 are both arranged as cross bars, so that the first limiter 17 and the second limiter 18 can effectively limit the shaking of the battery stack 5 during transportation, prevent the battery stack 5 from moving laterally, and enhance the overall stability.

[0062] Furthermore, a plurality of first limiting members 17 and a plurality of second limiting members 18 may be provided.

[0063] Multiple first limiters 17 and multiple second limiters 18 act together on the battery stack 5, forming a multi-limiting protection. This design can more effectively limit the shaking and displacement of the battery stack 5, thereby significantly enhancing the stability and safety of the structure. At the same time, by providing multiple limiters, the force points can be dispersed to multiple locations, avoiding damage or failure caused by excessive force on a single point. This distributed force method helps to extend the service life of the limiters and improve the durability of the structure.

[0064] In this embodiment, a plurality of clamping members 7 are provided at the other end of each of the first clamping arm 1 and the second clamping arm 2 .

[0065] The design of multiple clamping members 7 enables the clamping arm to contact the battery stack 5 at multiple points, thereby enhancing the clamping ability. This multi-point clamping method helps ensure that the battery stack 5 remains stable during transportation and is not easily dislodged or shaken. By distributing the force across multiple clamping members 7, it can avoid clamping failure or damage caused by excessive force at a single point. This distributed force method improves the reliability and durability of the clamping structure.

[0066] Furthermore, the clamping member 7 may adopt a telescopic structure, which enables the clamping member 7 to adapt to battery stacks 5 of different sizes and shapes, thereby enhancing the versatility of the clamp.

[0067] In this embodiment, please refer to Figure 3 The rotating shaft 3 includes: a rotating shaft bolt 19 and a rotating shaft nut 20. The rotating shaft bolt 19 passes through the first clamping arm 1 and the second clamping arm 2 in sequence and is connected to the rotating shaft nut 20 to realize the rotational connection between the first clamping arm 1 and the second clamping arm 2.

[0068] The shaft bolt 19 and shaft nut 20 are typically made of high-strength materials, capable of withstanding significant torque and shear forces, ensuring a secure and reliable connection between the first clamping arm 1 and the second clamping arm 2. Furthermore, the shaft nut 20 typically employs a locking design, such as a locking washer or a thread locker, to prevent loosening due to vibration or impact, thereby ensuring a durable and stable connection.

[0069] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0070] It should also be noted that, in this specification, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive.
