[0042] The embodiment of the present application provides a capacitor connection structure for installing and fixing a capacitor 001, which is commonly used in electric vehicles.

[0043] Reference Figures 1 to 8 , the capacitor connection structure comprises:

[0044] A shell assembly 1, a conductive copper busbar 2 and at least one shock-absorbing member 3, wherein the shell assembly 1 has a storage space therein, the storage space is used to set a capacitor 001, the conductive copper busbar 2 is arranged in the shell assembly 1, and the conductive copper busbar 2 is used to form a detachable connection with the capacitor 001, and the shock-absorbing member 3 is arranged between the shell assembly 1 and the capacitor 001.

[0045] like Figure 1 and Figure 2 As shown, a receiving groove can be provided in the housing component 1 to form a receiving space, and the receiving space can be used to receive and fix the capacitor 001. For example, multiple receiving grooves can be provided in the housing component 1, so that multiple capacitors 001 can be received and fixed.

[0046] like Figures 4 to 6 As shown, the conductive copper bar 2 is detachably connected to the capacitor 001, which can facilitate the quick installation and replacement of the capacitor 001, and can also improve the flexibility and maintainability of the overall capacitor connection structure. This design allows for quick and convenient operation when a single capacitor 001 needs to be repaired or replaced, reducing maintenance time and cost.

[0047] Specifically, the conductive copper bus 2 forms a detachable connection with the capacitor 001, so that the conductive copper bus 2 forms a detachable connection with the positive and negative electrodes of the capacitor 001, and it is also convenient to realize the electrical connection between the capacitor 001 and the conductive copper bus 2. Thus, a reliable connection between the capacitor 001 and the external circuit can be ensured, which helps to ensure the stable operation of the electrical system of the energy storage device using the capacitor connection structure, and also improves the reliability of the electrical system of the energy storage device using the capacitor connection structure.

[0048] Among them, the conductive copper busbar 2 can be provided with a threaded hole, and the positive and negative electrodes of the capacitor 001 can be provided with external threads adapted to the threaded hole, so that the conductive copper busbar 2 forms a threaded fit with the positive and negative electrodes of the capacitor 001; or, the conductive copper busbar 2 can be provided with a groove, and the positive and negative electrodes of the capacitor 001 can be provided with a protrusion adapted to the groove, so that the conductive copper busbar 2 forms a snap-fit ​​fit with the positive and negative electrodes of the capacitor 001.

[0049] Furthermore, the shock absorbing member 3 is arranged between the housing assembly 1 and the capacitor 001, which can effectively reduce the vibration amplitude of the capacitor 001 caused by changes in the external environment (such as vibration, impact, etc.), thereby protecting the internal structure of the capacitor 001, reducing the risk of performance degradation or damage of the capacitor 001 caused by vibration, and improving the reliability and stability of the capacitor connection structure. According to the actual layout requirements, the shock absorbing member 3 can be directly clamped between the housing assembly 1 and the capacitor 001, or the shock absorbing member 3 can be indirectly clamped between the housing assembly 1 and the capacitor 001, both of which can achieve the shock absorbing and buffering effect of the shock absorbing member 3.

[0050] Optionally, two conductive copper bars 2 are included, each of which is provided with a connection hole 21 , one of the conductive copper bars 2 is used to form a detachable connection with the positive electrode of the capacitor 001 , and the other of the conductive copper bars 2 is used to form a detachable connection with the negative electrode of the capacitor 001 .

[0051] like Figures 4 to 6 As shown, two conductive copper bars 2 can be provided, one conductive copper bar 2 is detachably connected to the positive electrode of the capacitor 001, and the other conductive copper bar 2 is detachably connected to the negative electrode of the capacitor 001, so that the capacitor 001 can be detachably connected to the capacitor connection structure, which can facilitate the maintenance and replacement of a single or multiple capacitors 001, and reduce maintenance costs. This design also increases the flexibility of the capacitor connection structure, improves maintainability, and reduces maintenance costs and time.

[0052] Among them, Figures 4 to 6 , Figure 8 As shown, a connection hole 21 can be provided on the conductive copper bus 2, and the connection hole 21 can form a detachable connection with the positive and negative electrodes of the capacitor 001. For example, the connection hole 21 can be set as a threaded hole, and the positive and negative electrodes of the capacitor 001 have external threads adapted to the threaded hole, so that the conductive copper bus 2 and the positive and negative electrodes of the capacitor 001 can form a threaded fit; or, the connection hole 21 can be set as a smooth through hole, and the positive and negative electrodes of the capacitor 001 have protrusions adapted to the smooth through hole, so that the conductive copper bus 2 and the positive and negative electrodes of the capacitor 001 can form a snap fit.

[0053] Optionally, the connection hole 21 is a threaded hole, and the connection hole 21 can form a threaded connection with the positive electrode and the negative electrode of the capacitor 001.

[0054] like Figure 7 and Figure 8As shown, the connection hole 21 can be set as a threaded hole, and the positive and negative electrodes of the capacitor 001 have external threads adapted to the threaded holes, so that the conductive copper bus 2 can form a threaded fit with the positive and negative electrodes of the capacitor 001, thereby ensuring the reliability and stability of the connection between the capacitor 001 and the capacitor connection structure. It can also reduce the contact resistance between the conductive copper bus 2 and the capacitor 001, and improve the efficiency of current transmission.

[0055] The capacitor 001 electrode material and the conductive copper busbar 2 can be oxygen-free copper, which can improve the conductivity and effectively reduce the internal resistance and heat generation of the product during operation. The conductive copper busbar 2 is a planar porous structure design, has good heat dissipation, is easy to process, and is economical.

[0057] Specifically, the first side, the second side and the third side are three adjacent sides of the capacitor 001, that is, the length side, the width side and the height side of the capacitor 001. Figures 2 to 6 As shown, the shock absorber 3 can be arranged between the inner wall of the shell component 1 and any one side of the capacitor 001; the shock absorber 3 can also be arranged between the inner wall of the shell component 1 and any two adjacent sides of the capacitor 001; the shock absorber 3 can also be arranged between the inner wall of the shell component 1 and any three adjacent sides of the capacitor 001, so as to meet different buffering and shock absorption requirements.

[0058] Among them, by arranging the shock absorbing members 3 at multiple positions between the capacitor 001 and the inner wall of the housing assembly 1, it is possible to achieve all-round shock absorption and protection for the capacitor 001, and also to protect the internal structure and performance of the capacitor 001 to the greatest extent. Moreover, the distribution arrangement of multiple shock absorbing members 3 can also more effectively disperse and absorb vibration energy, further improve its buffering and shock absorbing effect, thereby reducing the risk of damage to the capacitor 001 due to vibration and extending the service life of the capacitor 001.

[0059] In addition, according to the vibration environment of a specific application, the position and number of the shock absorbing member 3 can be adjusted so that the capacitor connection structure can better adapt to different vibration environments and ensure the stable operation of the capacitor 001.

[0060] Optionally, an insulating shell 4 is further included, and the insulating shell 4 is arranged in the shell assembly 1. The accommodating space is formed in the insulating shell 4.

[0061] like Figures 2 to 6 As shown, the insulating shell 4 is used to accommodate and install a single or multiple capacitors 001, which can facilitate the installation and removal of the capacitor 001 and protect the internal capacitor 001. The setting of the insulating shell 4 can provide a stable working environment for the capacitor 001, can reduce the direct contact between the capacitor 001 and the external environment, and help to reduce the performance fluctuations of the capacitor 001 caused by external factors (such as temperature, humidity changes, etc.), thereby improving the stability of the energy storage device using the capacitor connection structure. In addition, the capacitor 001 is installed in the insulating shell 4, and the capacitor 001 can also be isolated from the external conductive part, thereby improving the electrical safety of the energy storage device using the capacitor connection structure.

[0062] In addition, a shock absorber 3 can be set between the side wall of the shell assembly 1 and the side wall of the insulating shell 4, and between the lower surface of the top wall (or the upper surface of the bottom wall) of the shell assembly 1 and the conductive copper bus 2. A shock absorber 3 can also be set between the side wall of the shell assembly 1 and the side wall of the insulating shell 4, and between the lower surface of the top wall (or the upper surface of the bottom wall) of the shell assembly 1 and the conductive copper bus 2. By adjusting the arrangement position of the shock absorber 3, it is possible to adapt to vibration conditions in different directions, thereby achieving the effect of protecting the internal capacitor 001.

[0063] Optionally, an insulating plate 5 is further included, and the insulating plate 5 is arranged on a side of the conductive copper bus 2 away from the capacitor 001 .

[0064] like Figures 2 to 6 As shown, the provision of the insulating plate 5 can isolate the direct contact between the conductive copper bus 2 and the external environment, preventing the risk of electrical short circuit or leakage caused by accidental touch or other external factors, thereby improving the electrical safety performance of the capacitor connection structure. Moreover, by providing the insulating plate 5 on the conductive copper bus 2, the influence of electromagnetic interference on the capacitor 001 can also be effectively reduced, ensuring the normal operation of the capacitor 001.

[0065] In addition, the provision of the insulating plate 5 can also enhance the overall stability of the capacitor connection structure, and can prevent the conductive copper bus 2 from being displaced or deformed due to vibration or external impact, thereby ensuring a stable connection between the capacitor 001 and the conductive copper bus 2, and also helping to improve the connection reliability of the capacitor connection structure and extend the service life of the capacitor connection structure.

The first seal 6 is used to seal the gap between the two, which can prevent the risk of electrical leakage or short circuit and improve the electrical insulation performance of the entire capacitor connection structure.

[0068] Furthermore, by sealing the gap between the insulating plate 5 and the insulating shell 4 with the first seal 6, the stability and reliability of the entire capacitor connection structure can be enhanced, and the risk of loosening and displacement caused by vibration or impact can be reduced, thereby improving the connection reliability of the capacitor connection structure. In addition, the provision of the first seal 6 can also prevent impurities such as moisture and dust in the external environment from entering the interior of the insulating shell 4, thereby protecting the capacitor 001 and the conductive copper bus 2 from contamination and corrosion, and also expanding the adaptability of the capacitor connection structure.

[0071] A second shock absorber 32 is sandwiched between the side wall of the shell assembly 1 and the side wall of the insulating shell 4, that is, the second shock absorber 32 is arranged along the circumference of the capacitor connection structure, so that the first shock absorber 31 can perform buffering and shock absorption along the circumference of the capacitor connection structure and protect the capacitor 001 inside.

[0072] Optionally, the first shock absorbing member 31 includes a shock absorbing spring and / or a shock absorbing sleeve, and the second shock absorbing member 32 includes a shock absorbing spring and / or a shock absorbing sleeve. According to actual shock absorbing requirements, a shock absorbing spring, a shock absorbing sleeve or other elastic structure can be selected accordingly, and the corresponding shock absorbing effect can be achieved by utilizing its elastic deformation ability and elastic recovery ability.

[0075] In addition, the design of multiple shock absorbing members 3 increases the shock absorbing area and the number of shock absorbing points, thereby being able to improve the shock absorbing effect of the capacitor connection structure.

[0078] In addition, the design of the air inlet 121 and the air outlet 111 on the shell assembly 1 can also optimize the heat dissipation performance of the capacitor connection structure, so that the capacitor 001 can operate in a more stable working environment, reducing the performance fluctuation or failure risk caused by overheating of the capacitor 001, and ensuring that the capacitor 001 maintains an appropriate temperature during operation, thereby improving safety.

[0079] Optionally, the shell assembly 1 includes a first shell 11 and a second shell 12, the first shell 11 and the second shell 12 enclose the accommodating space, one of the air inlet 121 and the air outlet 111 is located on the first shell 11, and the other of the air inlet 121 and the air outlet 111 is located on the second shell 12.

That is, the housing assembly 1 may be a split design, so that the assembly process of the entire housing assembly 1 is more convenient. When it is necessary to maintain the capacitor 001 or other structures inside, only the first housing 11 or the second housing 12 may be disassembled, thereby improving the convenience of maintenance.

[0081] In addition, by providing the housing assembly 1 including the first housing 11 and the second housing 12 , the rigidity and impact resistance of the entire housing assembly 1 can be improved, which helps to protect the internal capacitor 001 or other structures from external vibration or impact.

[0082] Furthermore, the air inlet 121 and the air outlet 111 are respectively arranged on the first shell 11 and the second shell 12, which helps to form a more reasonable air circulation path. This design can ensure that cold air enters the accommodation space from the air inlet 121, and after sufficient heat exchange with the heating element, it is smoothly discharged from the air outlet 11, thereby improving the heat dissipation efficiency of the capacitor connection structure.

Through holes can also be opened on the first housing 11, the second housing 12 and the second sealing member 13 respectively, and the structure can be strengthened by bolt connection. The provision of the second sealing member 13 can enhance the sealing performance between the first housing 11 and the second housing 12, and can effectively prevent external impurities such as dust and moisture from entering the interior of the housing assembly 1, thereby protecting the capacitor 001 and other internal structures from pollution and damage.
