Description

Technical Field

[0001] This utility model belongs to the technical field of battery copper busbar components, specifically relating to a fuel cell copper busbar component. Background Technology

[0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy. It is also known as an electrochemical generator. In order to ensure the transmission of current and connection of electrical equipment in the circuit, a copper busbar assembly is usually installed inside the fuel cell. The existing copper busbar assembly is a mounting component that is fixedly installed inside the fuel cell for transmitting current and connecting electrical equipment, which is convenient for fixed installation and use.

[0003] In existing battery copper busbar assemblies, the copper busbars are directly fixed by rotating bolts into the internal threaded holes during installation. This process then secures the copper busbar assembly to the fuel cell. When the fuel cell is subjected to external forces and vibrations after installation, the installed copper busbar assembly vibrates accordingly. Prolonged vibration causes the bolts to loosen, resulting in a less secure installation or even detachment of the copper busbar assembly, leading to poor contact and reduced installation effectiveness. This compromises the anti-loosening and reinforcement properties of the copper busbar assembly when used on the fuel cell. Therefore, this invention proposes a fuel cell copper busbar assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a copper busbar assembly for a fuel cell, in order to solve the problem mentioned in the background art that when the copper busbar assembly is fixedly installed on the fuel cell and the fuel cell is subjected to vibration by external forces after installation, the installed copper busbar assembly will vibrate accordingly. Prolonged vibration will cause the bolts to loosen, resulting in the copper busbar assembly not being securely installed, or even falling off, leading to poor contact and reduced installation and use performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fuel cell copper busbar assembly, comprising a copper busbar assembly body, wherein the copper busbar assembly body includes copper busbar one and copper busbar three, wherein copper busbar one and copper busbar three are provided with internally threaded holes at equal intervals inside, and copper busbar two is provided at equal intervals at the connection between the upper surface of copper busbar one and copper busbar three, wherein both ends of copper busbar two are provided with fixing bolts, and the fixing bolts are matched with the internal thread structure of the internally threaded holes, and copper busbar four is fixed to one end of the upper surface of copper busbar two by mounting bolts, and the copper busbar assembly body is also provided with:

[0006] An anti-loosening reinforcement mechanism is provided, and the anti-loosening reinforcement mechanism includes a pushing component disposed at the bottom end of the internal threaded hole, a pressing reinforcement component disposed on both sides of the pushing component, and a reset component disposed inside the pressing reinforcement component;

[0007] The positioning and installation mechanism includes a positioning and installation component disposed at the connection point between the two ends of the copper busbar and the first and third copper busbars.

[0008] Preferably, the pushing component includes a groove at the bottom of the internal threaded hole, with connecting grooves on both sides of the top of the groove, a pressing connecting rod sliding at the bottom of the internal threaded hole, and an inner inclined push plate located inside the groove at the bottom of the pressing connecting rod.

[0009] Preferably, the extrusion reinforcement assembly includes reinforcement clamps disposed on both sides inside the groove, and the top of the reinforcement clamps extends into the interior of the connecting groove. The bottom end of the reinforcement clamps is integrally provided with a trapezoidal push block, and the trapezoidal push block matches the end inner surface structure of the inner inclined push plate.

[0010] Preferably, the two reinforcing plates are symmetrically arranged, and the top of the reinforcing plates is in contact with the outer surface of the fixing bolt.

[0011] Preferably, the reinforcing clamp has an internal sliding limit rod, and the limit rod is fixedly connected to the inner side of the groove by a thread.

[0012] Preferably, the reset assembly includes reset springs fixed at both ends of the upper surface of the inner inclined push plate and the connection point of the top end of the groove, and a reset elastic plate is provided at the connection point of the rear surface of the reinforcing clamp and the inner side of the connecting groove.

[0013] Preferably, the positioning and installation component includes two positioning plates integrally disposed at both ends of the second copper busbar, and positioning slots are equidistantly provided on the sides of the first and third copper busbars, and the internal structure of the positioning plates matches that of the positioning slots.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing an anti-loosening reinforcement mechanism, when the end of the fixing bolt rotates into the internal threaded hole, it can compress and move the extrusion connecting rod. The movement of the extrusion connecting rod causes the inner inclined push plate to move downward. The downward movement of the inner inclined push plate compresses the trapezoidal push block, so that when the trapezoidal push block is compressed, it drives the reinforcement clamp to move laterally in a stable manner. The top of the reinforcement clamp is clamped and fixed to the bottom surface of the fixing bolt for reinforcement and installation. This makes it easier for the copper busbar assembly body to be installed on the battery. When the fuel cell is subjected to external force vibration that causes the copper busbar assembly body to vibrate, it is less likely to cause the fixing bolt to loosen or fall off, thus improving the anti-loosening and reinforcement fixation of the copper busbar assembly body installed on the fuel cell.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a fuel cell copper busbar assembly, including a copper busbar assembly body 100, the copper busbar assembly body 100 including a copper busbar one 101 and a copper busbar three 103, the copper busbar one 101 and the copper busbar three 103 having internally threaded holes 106 equidistantly opened inside, a copper busbar two 102 being equidistantly arranged at the connection between the upper surface of the copper busbar one 101 and the copper busbar three 103, both ends of the copper busbar two 102 being provided with fixing bolts 105, and the fixing bolts 105 matching the internal thread structure of the internally threaded holes 106, a copper busbar four 104 being fixed to one end of the upper surface of the copper busbar two 102 by mounting bolts, and the copper busbar assembly body 100 also being provided with:

[0024] The anti-loosening reinforcement mechanism includes a pushing component located at the bottom of the internal threaded hole 106, and pressing reinforcement components on both sides of the pushing component. The pressing reinforcement components have a reset component inside. After the copper busbar 102 is fixedly installed by the fixing bolt 105, the anti-loosening reinforcement mechanism can reinforce the fixing bolt 105 again, thereby facilitating the reinforcement installation of the copper busbar 102. Even when the copper busbar assembly body 100 is subjected to vibration after installation, it remains reinforced and is not prone to loosening.

[0025] To facilitate the lateral adjustment and reinforcement installation of the trapezoidal push block 1054 and the reinforcing clamp 1052 via the pushing component, in this embodiment, preferably, the pushing component includes a groove 1051 formed at the bottom end of the internal threaded hole 106. Connecting grooves 1059 are formed on both sides of the top end of the groove 1051. A pressing connecting rod 1055 slides at the bottom end of the internal threaded hole 106. An inner inclined push plate 1053 is provided at the bottom end of the pressing connecting rod 1055 inside the groove 1051. When the pressing connecting rod 1055 is moved down to move the inner inclined push plate 1053, the inner inclined push plate 1053 is pressed against the surface of the trapezoidal push block 1054, thereby moving the reinforcing clamp 1052 for reinforcement installation.

[0026] To facilitate the reinforcement installation of the fixing bolt 105 after thread rotation using the compression reinforcement assembly, in this embodiment, preferably, the compression reinforcement assembly includes reinforcement clamps 1052 disposed on both sides inside the groove 1051. A limiting slide rod 1057 slides inside the reinforcement clamp 1052, and the limiting slide rod 1057 is threadedly fixed to the inner side of the groove 1051. This facilitates stable control of the compression movement of the reinforcement clamp 1052 within the limiting slide rod 1057, ensuring stability. The device is designed for fixed-movement reinforcement installation, with the top of the reinforcement clamp 1052 extending into the interior of the connecting groove 1059. The bottom end of the reinforcement clamp 1052 is integrally provided with a trapezoidal push block 1054, which matches the inner surface structure of the end of the inner inclined push plate 1053. When the inner inclined push plate 1053 presses against the trapezoidal push block 1054 and pushes it, the groove 1051 is moved and clamped for fixed installation by the trapezoidal push block 1054, which facilitates reinforcement installation and use.

[0027] To facilitate the quick repositioning of the extrusion connecting rod 1055 and the reinforcing clamp 1052 after disassembly using a repositioning assembly, in this embodiment, preferably, the repositioning assembly includes a repositioning spring 1058 fixed at both ends of the upper surface of the inner inclined push plate 1053 and the connection point of the inner top of the groove 1051. The extrusion connecting rod 1055 can be repositioned by the repositioning spring 1058. A repositioning elastic plate 1056 is provided at the connection point between the rear surface of the reinforcing clamp 1052 and the inner side of the connecting groove 1059, and the reinforcing clamp 1052 is repositioned by the repositioning elastic plate 1056.

[0028] The positioning and installation mechanism includes a positioning and installation component disposed at the end of the copper busbar 2 102 where it connects with the copper busbar 1 101 and the copper busbar 3 103. The positioning and installation mechanism can position and install the copper busbar 2 102 during assembly and installation, and facilitate its fixed use.

[0029] To facilitate the positioning and installation of copper busbar 2 102 using the positioning and installation component, in this embodiment, preferably, the positioning and installation component includes two positioning plates 1021 integrally disposed at both ends of copper busbar 2 102. Positioning slots 1022 are equidistantly provided on the sides of copper busbar 1 101 and copper busbar 3 103, and the internal structure of the positioning plates 1021 matches the internal structure of the positioning slots 1022. Copper busbar 2 102 can be positioned and fixedly installed by positioning and engaging the positioning plates 1021 inside the positioning slots 1022.

[0030] The working principle and usage process of this utility model are as follows: When using this type of fuel cell copper busbar assembly, it is first fixedly installed. The positioning plate 1021 can be positioned and engaged inside the positioning slot 1022 to position and install both ends of the copper busbar 102 with the copper busbar 101 and the copper busbar 3 103. This makes it easy to accurately position and fix the copper busbar 102, and it is not easy to shift during installation. Then, the fixing bolt 105 is rotated and inserted into the internal thread hole 106 to fix the copper busbar 102 with the copper busbar 101 and the copper busbar 3 103. Finally, the copper busbar 4 104 is fixedly installed on the surface of the copper busbar 102, which makes it easy to assemble the copper busbar assembly body 100 and fix it to the fuel cell for use.

[0031] Then, when the copper busbar assembly body 100 is assembled, the fixing bolt 105 is inserted into the internal threaded hole 106 and rotated for installation. When the end of the fixing bolt 105 rotates into the internal threaded hole 106, the bottom end continues to rotate and presses the extrusion connecting rod 1055, causing the extrusion connecting rod 1055 to move and drive the inner inclined push plate 1053 to move downward. The inner inclined push plate 1053 moves downward and contacts the inner surface of the trapezoidal push block 1054, pressing the trapezoidal push block 1054. When the trapezoidal push block 1054 is pressed, it is located on the outer surface of the limit slide rod 1057, which drives the reinforcing clamp 1052 to stabilize. The reinforcing clamp 1052 is moved laterally until the top end of the reinforcing clamp 1052 is moved inside the connecting groove 1059. The top end of the reinforcing clamp 1052 is clamped and fixed to the bottom surface of the fixing bolt 105 for reinforcement and installation. This facilitates the strengthening and fixing of the fixing bolt 105 during rotational installation, making it more secure after installation. This ensures that when the copper busbar assembly body 100 is installed on the battery, the fixing bolt 105 is less likely to loosen or fall off when the copper busbar assembly body 100 vibrates due to external force vibration during fuel cell use. This improves the anti-loosening and strengthening fixation of the copper busbar assembly body 100 installed on the fuel cell.
