Description

Technical Field

[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a vehicle-mounted capacitor fixing and shockproof device. Background Technology

[0002] With the development and popularization of new energy vehicles, automotive-grade components will be used in a standardized manner. For capacitors, mandatory certification will be implemented, and manufacturers must meet the requirements to be allowed entry. Regarding the single measure of capacitor vibration safety certification, most automakers currently use adhesive bonding for reinforcement and the entire unit is compacted by the upper and lower covers of the onboard computer (OBC). Capacitor manufacturers are forced to passively meet customized sizes and heights to satisfy automakers' design requirements, and universal standard products are not widely used. This is especially true for high-voltage electrolytic capacitors used in onboard OBCs, which are manufactured with a design height that is almost perfectly matched to the OBC casing, forcing the capacitor body to be clamped in a fixed, larger space, triggering greater vibration factors. Furthermore, the core of an aluminum electrolytic capacitor is supported by electrolytic paper at both ends or one end, with the core foils lifted by the paper's creep. Excessive vibration creep will gradually break the electrolytic paper fibers, causing it to lose its insulating function and eventually leading to a short circuit and failure.

[0003] Therefore, it is necessary to conduct research and development to provide a solution that proactively addresses the problem of capacitor vibration failure.

[0029] Reference Figures 1-3 As shown in the figure, as an embodiment of the present invention, a vehicle-mounted capacitor fixing and shock-absorbing device 100 is provided for installing and fixing a capacitor 200. The vehicle-mounted capacitor fixing and shock-absorbing device 100 includes: a capacitor fixing frame 10 and fixing feet 20 extending from the capacitor fixing frame 10; wherein, the capacitor fixing frame 10 has a through square frame structure, and the capacitor fixing frame 10 is provided with a capacitor receiving space 101 to accommodate the capacitor; fastening pieces are staggered on the side of the capacitor fixing frame 10 to fasten the capacitor 100 in the capacitor receiving space 101; both ends of the capacitor fixing frame 10 are provided with square openings, and the fixing feet 20 extend from the four corners of the square opening at one end, and are fixedly installed on the circuit board or external device by means of the fixing feet 20.

[0030] Please refer to Figure 3 As shown, the capacitor fixing frame 10 includes a first side 11, a second side 12, a third side 13, and a fourth side 14. The first side 11, the second side 12, the third side 13, and the fourth side 14 are gathered together to form a through capacitor receiving space 101 to accommodate the capacitor body. In some embodiments, the capacitor receiving space 101 is generally a through square hole.

[0031] Reference Figure 3 , Figure 4 As shown, a first window 110 is provided on the first side 11, and a first fastening piece 111 is provided at the first window 110. In some embodiments, the first window 110 extends longitudinally along the capacitor fixing frame 10; the first fastening piece 111 corresponds to the first window 110 extending longitudinally along the capacitor fixing frame 10. In some embodiments, the first window 110 is an upright rectangular opening, the length of the first fastening piece 111 is equal to or less than the length of the rectangular opening; the width of the first fastening piece 111 is less than or equal to the width of the rectangular opening; and the thickness of the first fastening piece 111 is less than or equal to the thickness of the first side 11.

[0032] Reference Figure 4 As shown, the first fastening piece 111 includes a main body 1101, a connecting part 1102, and a clamping part 1103. The main body 1101 is fixedly connected to the edge of the first window 110, while the clamping part 1103 is not fixed. The fastening piece is designed to be inclined from the connecting part to the clamping part, so that when the clamping part 1103 is displaced laterally within the capacitor fixing frame 10, the fastening piece can generate elastic force. In some embodiments, the clamping part 1103 and the main body 1101 are on different planes, and the clamping part 1103 is connected to the main body 1101 through a connecting part 1102 formed by two progressively inwardly tapering arc-shaped inclined surfaces. In some embodiments, the clamping part 1103 is designed as an arc-shaped piece, and the inner surface of the arc-shaped piece is configured to match the surface of the capacitor, so that the clamping part can closely contact the surface of the capacitor, resulting in more stable and reliable clamping. In some embodiments, the thickness of the clamping part 1103 is less than the thickness of the main body 1101. In another embodiment, one end of the first fastening piece 111 is a fixed end for fixing to the edge of the first window 110; the other end of the first fastening piece 111 is a free end for elastically clamping the capacitor. The free end extends longitudinally upward along the first window 110 and obliquely toward the capacitor receiving space 101. The free end and the fixed end are on different planes, and the free end is arranged in an arc-shaped sheet that matches the surface of the capacitor.

[0033] Reference Figure 3As shown, in one embodiment, the second side 12 is adjacent to the first side 11, and a second window 120 is provided on the second side 12. A second fastening piece 121 is provided at the second window. The shape of the second window 120 is the same as the shape of the first window 110, and the extending direction of the second fastening piece 121 is opposite to the extending direction of the first fastening piece 111. The structure of the second fastening piece 121 is the same as the structure of the first fastening piece 111, and will not be described again here.

[0034] Reference Figure 2 , Figure 3 As shown, the first side 11 is opposite to the third side 13, and the second side 12 is opposite to the fourth side 14. A third window (unlabeled) is provided on the third side 13, and a third fastening piece 131 is provided at the third window. A fourth window (unlabeled) is provided on the fourth side 14, and a fourth fastening piece 141 is provided at the fourth window. The extension direction of the third fastening piece 131 is the same as that of the first fastening piece 111, and the extension direction of the fourth fastening piece 141 is opposite to that of the first fastening piece 111, thus forming an interleaved clamping layout. This improves the balance and stability of the clamped capacitor body, allowing the capacitor body to be stably installed and fixed to the fixing device. The structures of the first fastening piece 111, the second fastening piece 121, the third fastening piece, and the fourth fastening piece are completely identical; for details, please refer to the description of the first fastening piece 111, which will not be repeated here.

[0035] Reference Figure 2 As shown, in some embodiments, the clamping portions of the first fastening plate 111, the second fastening plate 121, the third fastening plate, and the fourth fastening plate together form a circular clamping space; in some embodiments, the inner diameter of the circular clamping space is less than or equal to the outer diameter of the capacitor body. When the capacitor is placed in the capacitor receiving space 101, the clamping portions of the first fastening plate 111, the second fastening plate 121, the third fastening plate, and the fourth fastening plate tightly clamp the capacitor, thereby firmly fixing the capacitor.

[0036] Reference Figures 3-4 As shown, in the first side 11, the second side 12, the third side 13, and the fourth side 14, an arc-shaped ridge is provided at the connection point of every two adjacent sides, and the arc-shaped ridge forms an arc-shaped groove on the inner wall of the receiving space. This arrangement can improve the shock absorption performance of the main body and at the same time, it can stably place the capacitor body in the receiving space.

[0037] Reference Figure 2 , Figure 3As shown, in some embodiments, the first side 11, the second side 12, the third side 13, and the fourth side 14 have the same shape, all being rectangular. In some embodiments, the first side 11, the second side 12, the third side 13, and the fourth side 14 have the same thickness. In some embodiments, two opposing sides (such as the first side 11 and the third side 13, the second side 12 and the fourth side 14) are arranged parallel to each other, and the distance between two opposing sides is equal to the outer diameter of the capacitor body placed in the receiving space. In some embodiments, the distance between two opposing sides is greater than the outer diameter of the capacitor body placed in the receiving space.

[0038] Reference Figure 3 As shown, there are at least two fixing feet 20, both of which are located at the same end of the capacitor fixing frame 10. The extending direction of the fixing feet 20 is perpendicular to the plane of the capacitor cover, or the angle between the extending direction of the fixing feet 20 and the plane of the square opening is greater than zero degrees. In some embodiments, the extending direction of the fixing feet 20 is the same as the extending direction of the capacitor's leads. In some embodiments, the two fixing feet 20 are arranged diagonally, and the line connecting the two fixing feet 20 intersects the line connecting the two leads of the capacitor. In this embodiment, there are four fixing feet 20, all located at the same end of the capacitor fixing frame 10, and the four fixing feet 20 are connected sequentially to form the square opening. By arranging the fixing feet in this way, the capacitor can be stably fixed to the external circuit board, and since all the fixing feet 20 are located at the same end, damage to only a few fixing feet 20 will not significantly affect the overall fixation of the capacitor.

[0039] This invention uses interlocking fasteners to clamp and fix the capacitor, thereby stably and evenly mounting the capacitor 200 onto the fixing device 100. The structure is simple and the fixation is reliable.
