Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0028] The high-voltage DC converter serves as the distribution center of battery energy in the automotive field and as the distribution center of battery energy in automotive electricals, providing current distribution control for battery discharge and charging; in automotive electronics, it serves as the information processing center to realize receiving and feedback signals and making corresponding electrical circuit control and monitoring. In the DC converter, the X capacitor plays an important role. Currently, in the mainstream market design solutions for fixing the X capacitor, the potting method is often used, which involves the selection of glue and the use of potting equipment, resulting in high costs and low efficiency in fixing the X capacitor.
[0029] To this end, the present application provides a mounting bracket. The mounting bracket realizes positioning by clamping the X capacitor, eliminates the selection of glue and the use of glue filling equipment, and can improve the installation efficiency and save costs. It can be understood that the mounting bracket provided by the present application is not limited to mounting the X capacitor, and can also mount and fix other components, which is not limited herein.
[0030] Specifically, referring to Figure 1 and Figure 2 , the mounting bracket includes a bracket body 10. The bracket body 10 has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other in pairs. An installation cavity 11 is formed in the bracket body 10. The X capacitor is inserted into the installation cavity 11 along the first direction X. An elastic member 120 is arranged in the installation cavity 11. A clamping member 130 is arranged on the bracket body 10. The clamping member 130 extends along the first direction X. The clamping member 130 has a clamping surface 131. The clamping surface 131 is opposite to and spaced from the elastic member 120 in the first direction X. When the X capacitor is inserted into the installation cavity 11, the X capacitor is arranged between the elastic member 120 and the clamping surface 131. The elastic member 120 and the clamping member 130 cooperate to limit the position of the X capacitor in the first direction X.
[0031] By arranging the elastic member 120, when the X capacitor is inserted into the installation cavity 11, the X capacitor presses the elastic member along the first direction X, causing the elastic member 120 to generate a recoverable deformation along the first direction X. After the X capacitor is installed in the installation cavity 11, the elastic member 120 resets under its own elastic force; by arranging the clamping member 130, the clamping member 130 can limit the reverse movement of the X capacitor along the first direction X, and cooperate with the force applied by the elastic member 120 to the X capacitor in the reverse direction of the first direction X, and press the X capacitor tightly between the clamping surface 131 and the elastic member 120 to realize the positioning of the X capacitor in the first direction X. Thus, the mounting bracket provided by the present application realizes the positioning of the X capacitor in the first direction X through the cooperation of the elastic member 120 and the clamping surface 131 of the clamping member 130, avoids the selection of glue and the use of glue filling equipment involved in the glue filling method, and can improve the installation efficiency and save costs.
[0032] Furthermore, referring to Figures 1 to 4, a through groove 111 is formed in the bracket body 10. The through groove 111 penetrates the bracket body 10 along the first direction X. A plurality of through grooves 111 are provided, and adjacent through grooves 111 are spaced apart. The elastic member 120 is disposed between two adjacent through grooves 111. The elastic member 120 has an elastic portion 121 and a connecting portion 122. A plurality of connecting portions 122 are provided and are connected to both ends of the elastic portion 121. In this embodiment, the connecting portion 122 is specifically two. The two connecting portions 122 are respectively fixed to both ends of the elastic portion 121, and the connecting portion 122 and the elastic portion 121 are integrally formed. The connecting portion 122 is fixedly connected to the bracket body 10, and the elastic portion 121 protrudes toward the mounting cavity 11 along the reverse direction of the first direction X.
[0033] It can be understood that, in this embodiment, four through grooves 111 are provided and two elastic members 120 are provided. In other embodiments, the number of through grooves 111 is at least twice the number of elastic members 120, which is not limited herein. The elastic member 120 is specifically an elastic plastic sheet in this embodiment. The elastic member 120 can be deformed under its own elastic action. By providing the through groove 111, the normal deformation of the elastic member 120 is ensured.
[0034] In other embodiments, the elastic member 120 can also be a spring (not shown in the figure). A positioning hole (not shown in the figure) is formed in the inner wall of the bracket body 10 in the first direction X. The spring is disposed in the positioning hole. One end of the spring contacts the inner wall of the positioning hole, and the other end contacts the X capacitor. The spring can also generate a recoverable deformation along the first direction X when the X capacitor is inserted into the mounting cavity 11. The engaging member 130 can limit the reverse movement of the X capacitor along the first direction X and cooperate with the force exerted by the spring on the X capacitor toward the reverse direction of the first direction X to press the X capacitor tightly between the engaging surface 131 and the spring, so as to realize the positioning of the X capacitor in the first direction X.
[0035] In one embodiment, refer to Figure 1 and Figure 2, A plurality of clamping members 130 are provided and are oppositely arranged on the bracket body 10. In this embodiment, there are specifically four clamping members 130. In other embodiments, the number of clamping members 130 can be set according to the size of the X capacitor or the installation cavity 11, and no limitation is made here. The clamping member 130 includes a mounting portion 132 and a clamping portion 133. The mounting portion 132 is fixedly connected to the bracket body 10, and the clamping portion 133 is fixedly connected to the side of the mounting portion 132 away from the bracket body 10. The clamping surface 131 is arranged on the side of the clamping portion facing the bracket body 10. A slope 134 is provided on the clamping portion 133, and the slope 134 is arranged on the side of the clamping portion 133 away from the elastic member 120. The side of the slope 134 away from the mounting portion 132 is inclined towards the side close to the elastic member 120. Thus, when the X capacitor is inserted into the bracket body 10, the slope 134 can guide the X capacitor, and the clamping member 130 can be offset towards the outside of the installation cavity 11, facilitating the insertion of the X capacitor into the installation cavity 11. After the X capacitor is installed in place, the X capacitor is pressed tightly between the elastic portion 121 and the clamping surface 131, limiting the X capacitor and restricting the displacement of the X capacitor in the first direction X.
[0036] Further, referring to Figure 1 and Figure 3 , the bracket body 10 has a first surface 12 in the first direction X. The bracket body 10 also has two oppositely arranged second surfaces 13 and third surfaces 14. The installation cavity 11 is surrounded by the first surface 12, two second surfaces 13, and two third surfaces 14. Limiting members 140 are provided on both the second surface 13 and the third surface 14. The limiting members 140 are fixed on the second surface 13 and the third surface 14. The limiting members 140 are strip-shaped and extend along the first direction X. A guiding surface 141 is provided at one end of the limiting member 140 away from the first surface 12 in the first direction X. The side of the guiding surface 141 away from the second surface 13 or the third surface 14 where the limiting member 140 is located is inclined towards the side close to the first surface 12. When the X capacitor is inserted into the installation cavity 11, the guiding surface 141 can guide the X capacitor, facilitating the insertion of the X capacitor. After the X capacitor is inserted into the installation cavity 11, the limiting member 140 abuts against the side wall of the X capacitor, limiting the X capacitor in the second direction Y and the third direction Z and restricting the displacement of the X capacitor in the second direction Y and the third direction Z.
[0037] Specifically, referring to Figure 1 , in this embodiment, two limiting members 140 are provided on each second surface 13, and two limiting members 140 are also provided on each third surface 14, and the two limiting members 140 on each surface are arranged at intervals. It is not difficult to understand that in other embodiments, the number of limiting members 140 can be reasonably set according to the size of the installation cavity 11, and no limitation is made here.
[0038] Referring to Figure 1, in some embodiments, the bracket body 10 is provided with fixing holes 150. The fixing holes 150 penetrate the bracket body 10 along the first direction X. The fixing holes 150 are for a fixing member to pass through to fix the bracket body 10. The fixing member is used to fix the mounting bracket on the DC converter. The fixing member can be a bolt, a screw or a plug, etc., which is not limited herein.
[0039] Referring to Figure 3 , in some embodiments, the bracket body 10 is further provided with a positioning block 160. The positioning block 160 is L-shaped and is fixed on the outer wall of the bracket body 10. Wiring harnesses such as wires can be wound around the positioning block 160 to achieve the positioning and storage of the wiring harnesses.
[0040] In addition, the bracket body 10 is further provided with mounting holes 170. The mounting holes 170 are opened along the first direction X and are for the installation of copper bars.
[0041] The mounting bracket provided by the present application can not only be used for the installation of X capacitors, eliminating the potting step, reducing costs and being convenient for installation, which helps to improve the installation efficiency, but also can achieve the positioning and storage of wiring harnesses and the installation and positioning of copper bars, with high integration.
[0042] In addition, the present application further includes a direct converter including the above-mentioned mounting bracket. The DC converter provided by the present application can achieve the rapid installation of X capacitors, eliminating the potting step during installation, reducing cost investment, and the installation operation is simple and efficient.
[0043] As mentioned above, only some embodiments of the present application are described, and there is no restriction in any form on this application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modification, equivalent change and modification that can be easily thought of by those skilled in the art within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
