[0024] With the development of technology, new energy vehicles have been widely promoted. New energy vehicles are divided into pure electric vehicles and hybrid vehicles. Among them, OBC (Onboard Charger), DC-DC (Direct Current-Direct Current Converter), and PDU (Power Distribution Unit) are important components of electric vehicles.

[0025] In related technologies, the filter module of the on-board charger includes an inductor, an X capacitor, and a Y capacitor. The inductor, X capacitor, and Y capacitor are each independently mounted on the motherboard, which results in poor EMC (Electromagnetic Compatibility) shielding.

[0026] To address the aforementioned problems, this invention proposes a filter module 100, aiming to improve the poor EMC shielding effect. The specific structure of the filter module 100 will be described in detail below: Please see Figure 1 In one embodiment of the present invention, the filter module 100 includes a metal shell 10, an inductor 20, an X capacitor 30, and a Y capacitor 40; the inductor 20 is integrated inside the metal shell 10; the X capacitor 30 is integrated inside the metal shell 10 and connected to the inductor 20; the Y capacitor 40 is integrated inside the metal shell 10 and connected to the inductor 20 and the X capacitor 30.

[0027] It is understood that the technical solution of this utility model integrates the inductor 20, the X capacitor 30 and the Y capacitor 40 into the metal shell 10, so as to achieve the EMC shielding effect of the filter module 100 by using the metal shell 10, thereby effectively improving the problem of poor EMC shielding effect.

[0028] Furthermore, since the inductor 20, X capacitor 30, and Y capacitor 40 adopt an integrated design, the problem of components falling out of the metal casing 10 under vibration can be improved.

[0029] In this embodiment, the metal shell 10 is a housing structure used to integrate and fix components such as the inductor 20, X capacitor 30, and Y capacitor 40. The shape and size of the metal shell 10 are specifically determined by the shape and size of the components to be placed, including but not limited to square shells, cylindrical shells, etc. Furthermore, the material of the metal shell 10 can be, but is not limited to, aluminum, stainless steel, copper, silver, and other metal materials, as long as it can provide EMC shielding for the internal components.

[0030] The connection between inductor 20 and capacitor X 30 includes both electrical and rigid connections. The rigid connection between inductor 20 and capacitor X 30 can be achieved by directly connecting them using bolts, clips, or adhesive, or indirectly using additional structural components, as long as the connection between inductor 20 and capacitor X 30 is achieved. Similarly, the connection between inductor 20 and capacitor Y 40 includes both electrical and rigid connections. The rigid connection between inductor 20 and capacitor Y 40 can be achieved by directly connecting them using bolts, clips, or adhesive, or indirectly using additional structural components, as long as the connection between inductor 20 and capacitor Y 40 is achieved. Likewise, the connection between capacitor X 30 and capacitor Y 40 can be achieved directly using connecting wires or connecting tabs, as long as the connection between capacitor X 30 and capacitor Y 40 is achieved.

[0031] In practical applications, the arrangement of inductor 20, X capacitor 30, and Y capacitor 40 within the metal casing 10 includes, but is not limited to, stacking on top of each other or horizontal arrangement.

[0032] Please see Figure 1 In one embodiment of this utility model, the metal shell 10 is an aluminum shell or a stainless steel shell.

[0033] With this configuration, by using an aluminum or stainless steel shell as the metal shell 10, the problem of poor EMC shielding effect can be effectively improved. At the same time, the metal shell 10 can be made of aluminum or stainless steel with relatively low cost, while also ensuring that the metal shell 10 has sufficient hardness to provide sufficient pressure resistance to the components inside the metal shell 10.

[0034] Please see Figure 1 In one embodiment of this utility model, both the X capacitor 30 and the Y capacitor 40 are located above the inductor 20.

[0035] This arrangement, by integrating the X capacitor 30 and Y capacitor 40 above the inductor 20, fully utilizes the space above the inductor 20, thereby improving the layout rationality of the inductor 20, X capacitor 30, and Y capacitor 40. Furthermore, since the inductor 20, X capacitor 30, and Y capacitor 40 are typically mounted from the top of the metal casing 10 into its interior, and the inductor 20 is significantly larger than the X capacitor 30 and Y capacitor 40, it is easier to mount the smaller X capacitor 30 and Y capacitor 40 by first mounting the larger inductor 20 from the top of the metal casing 10 to its bottom position inside, and then mounting the smaller X capacitor 30 and Y capacitor 40 from the top of the metal casing 10 into its interior, above the inductor 20. This also avoids the larger inductor 20 compressing the smaller X capacitor 30 and Y capacitor 40.

[0036] In practical applications, X capacitor 30 and Y capacitor 40 can be stacked one on top of inductor 20, or they can be arranged at intervals on top of inductor 20 along the length or width of metal shell 10.

[0037] Please see Figure 1 In one embodiment of this utility model, the X capacitor 30 and the Y capacitor 40 are distributed at intervals along the width direction of the metal shell 10.

[0038] This arrangement allows the X capacitor 30 and Y capacitor 40 to be arranged along the width of the metal casing 10 according to their shape and size, which can further improve the layout rationality of the X capacitor 30 and Y capacitor 40, make full use of the space inside the metal casing 10, reduce the volume of the metal casing 10, and thus achieve the miniaturization design of the filter module 100.

[0039] Please see Figure 1 In one embodiment of this utility model, the inner bottom wall of the metal shell 10 is provided with an insulating base 21, and the inductor 20 is disposed on the insulating base 21.

[0040] With this setup, during installation, the inductor 20 is first mounted on the insulating base 21 to limit and fix the inductor 20. Then, the insulating base 21 and the inductor 20 are installed together inside the metal shell 10. Therefore, the design of the insulating base 21 not only limits and fixes the inductor 20 to improve the installation reliability of the inductor 20 and prevent the inductor 20 from shifting or even shaking inside the metal shell 10, but also provides insulation between the inductor 20 and the metal shell 10, preventing the inductor 20 from directly contacting the metal shell 10 and causing a short circuit.

[0041] In practical applications, the inductor 20 can be fixedly connected to the insulating base 21 by means of bolts, clips, adhesives, etc. In some embodiments, in order to achieve precise installation of the inductor 20, a positioning element can be provided on the insulating base 21. This positioning element can be a positioning post, and a positioning mating element that cooperates with the positioning element can be provided on the inductor 20. This positioning mating element can be a positioning groove, so that the precise positioning of the inductor 20 can be achieved through the mutual cooperation of the positioning element and the positioning mating element.

[0042] In practical applications, the insulating base 21 can be a plastic base or a wooden base, etc., which are structural components that provide insulation. No specific limitation is made here.

[0043] Please see Figure 1 In one embodiment of this utility model, an insulating support 22 is provided above the inductor 20, and the X capacitor 30 and Y capacitor 40 are mounted above the inductor 20 through the insulating support 22.

[0044] With this setup, during installation, an insulating bracket 22 can be installed above the inductor 20, and then the X capacitor 30 and Y capacitor 40 can be installed on the insulating bracket 22. The insulating bracket 22 can support the X capacitor 30 and Y capacitor 40 above the inductor 20. Therefore, the design of the insulating bracket 22 not only makes it easier to install the X capacitor 30 and Y capacitor 40, but also increases the electrical safety distance between the inductor 20 and the X capacitor 30 and Y capacitor 40.

[0045] In practical applications, the insulating bracket 22 can be fixedly connected to the inductor 20 by means of sleeve, bolt, clip, adhesive, etc. The X capacitor 30 and Y capacitor 40 can also be fixedly connected to the insulating bracket 22 by means of bolt, clip, adhesive, etc.

[0046] Please see Figure 1In one embodiment of the present invention, the insulating bracket 22 includes a plurality of insulating positioning blocks 221, which are distributed at intervals along the circumference of the inductor 20 so that the plurality of insulating positioning blocks 221 surround to form a mounting groove, and the X capacitor 30 and the Y capacitor 40 are installed in the mounting groove.

[0047] With this configuration, by using multiple insulating positioning blocks 221 to form an installation groove, the X capacitor 30 and the Y capacitor 40 can be installed within the installation groove formed by the multiple insulating positioning blocks 221, thus achieving precise installation of the X capacitor 30 and the Y capacitor 40.

[0048] Please see Figure 1 In one embodiment of this utility model, the top of the metal shell 10 is provided with a mounting port 11, and the inductor 20, the X capacitor 30 and the Y capacitor 40 are all installed into the metal shell 10 through the mounting port 11.

[0049] With this configuration, by providing an installation port 11 at the top of the metal casing 10, it is easier to smoothly install the inductor 20, X capacitor 30 and Y capacitor 40 into the interior of the metal casing 10 through the installation port 11 at the top during the installation process. Furthermore, during the subsequent potting process, it can prevent the potting compound that has not yet solidified from flowing out from the installation port 11.

[0050] Please see Figure 1 In one embodiment of this utility model, the metal shell 10 is filled with potting compound.

[0051] With this configuration, after installing the inductor 20, X capacitor 30, and Y capacitor 40 inside the metal casing 10, potting compound is poured into the inside of the metal casing 10. The pouring of potting compound can bond and fix the inductor 20, X capacitor 30, and Y capacitor 40 to the inside of the metal casing 10, preventing the components inside the metal casing 10 from vibrating and falling off under vibration. At the same time, the design of the potting compound can also play a role in heat conduction, transferring the heat generated by the inductor 20, X capacitor 30, and Y capacitor 40 to the outside of the metal casing 10, thereby improving the heat dissipation capacity of the components inside the metal casing 10.

[0052] For example, the potting compound can be polyurethane or epoxy resin.

[0053] This utility model also proposes an on-board charger, which includes a housing and a filter module 100. The specific structure of the filter module 100 is as described in the above embodiments. Since this on-board charger adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The filter module 100 is disposed inside the housing.

[0054] This utility model also proposes a vehicle that includes an on-board charger. The specific structure of the on-board charger is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
