[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1 to 3 As shown, in one embodiment, the insulating sheet 1 is applied to the power module to electrically isolate the housing 2 of the power module from the conductive components. The housing 2 has a mounting groove 21, and both the insulating sheet 1 and the conductive components are mounted in the mounting groove 21. A portion of the insulating sheet 1 is located between the conductive components and the bottom surface of the mounting groove 21, and a portion of the insulating sheet 1 is also located between the conductive components and the side surface of the mounting groove 21.

[0029] Specifically, the insulating sheet 1 includes a base plate 11 and a side plate 12; the side plate 12 is fixedly connected to the base plate 11; the side plate 12 protrudes from the base plate 11 along a first direction, and the side plate 12 and the base plate 11 are connected to form a bent structure; wherein, the base plate 11 is used to be disposed between the bottom surface of the mounting groove 21 and the conductive component, and the side plate 12 is used to be disposed between the side surface of the mounting groove 21 and the conductive component. Figure 1 and Figure 2 In the diagram, the first direction is parallel to the Z-axis, and this first direction can be either up or down.

[0030] In this embodiment, the insulating sheet 1 itself is a bent structure. When it is applied to the power module, it does not need to be bent again. Thus, it does not need to be bent with the help of corresponding jigs. Therefore, the setting of this embodiment can not only reduce the cost of related jigs required for assembling the power module, but also make the assembly operation of the power module simpler.

[0031] Furthermore, in existing technologies, when a flat insulating sheet is bent, the bent portion retains a certain degree of elasticity. Therefore, a corresponding structure is needed to limit the bent portion to keep the insulating sheet in a bent state, which may complicate the structural design of components such as the housing 2. The design of this application avoids this problem and simplifies the structure of components such as the housing 2.

[0032] Meanwhile, in existing technologies, the insulating sheet needs to be bent, so its material needs to be elastic. However, the arrangement in this embodiment can achieve the required function regardless of whether the material of the insulating sheet 1 is elastic. That is, the arrangement in this embodiment can also reduce the requirements on the type of material of the insulating sheet 1, which helps to reduce the material cost of the insulating sheet 1.

[0033] Furthermore, in the prior art, the insulating sheet has a flat structure, and its thickness is usually small to facilitate bending. In particular, the thickness of existing insulating sheets is usually less than 2 mm. However, in this embodiment, the insulating sheet 1 does not require additional bending during use, so the thickness of the insulating sheet (such as the thickness of the base plate 11 and the side plate 12) can be set to be larger, which can improve the insulation effect of the insulating sheet 1.

[0034] In one embodiment, the base plate 11 is a flat plate structure, such as a rectangular plate or an irregularly shaped plate, and its shape can be set according to actual needs. Furthermore, the thickness of the base plate 11 is greater than or equal to 0.2 mm and less than or equal to 0.3 mm. Here, the thickness of the base plate 11 refers to its dimension in the first direction.

[0035] In one embodiment, the side plate 12 is a flat plate structure, such as a rectangular plate or an irregularly shaped plate, and its shape can be set according to actual needs. Furthermore, the thickness of the side plate 12 is greater than or equal to 0.2 mm and less than or equal to 0.3 mm. The thickness of the side plate 12 refers to its dimension in the second direction. Additionally, the first direction intersects the second direction; furthermore, the first direction can be perpendicular to the second direction. Figure 1 and Figure 2 Of the directions shown, the second direction is parallel to the X-axis, and the second direction can be the width direction of the base plate 11.

[0036] In one embodiment, the side plate 12 and the bottom plate 11 are integrally formed. For example, they can be integrally formed by injection molding.

[0037] Alternatively, the base plate 11 and the side plate 12 can be set perpendicularly, in which case the included angle between the base plate 11 and the side plate 12 is a right angle. Of course, the included angle between the base plate 11 and the side plate 12 can also be an acute angle or an obtuse angle.

[0038] Furthermore, in the first direction, the side plate 12 may protrude from only one side surface of the base plate 11. Of course, in other examples, in the first direction, the side plate 12 may protrude from both sides surface of the base plate 11.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, in the second direction, the base plate 11 has a first surface 111 and a second surface 112 disposed opposite to each other; the first surface 111 is connected to a side plate 12; the second surface 112 is also connected to a side plate 12. After assembly, the conductive component is located between the two side plates 12, which can improve the insulation effect of the insulating sheet 1.

[0040] Of course, in other embodiments, when the side plate 12 is provided on the first surface 111, the side plate 12 may not be provided on the second surface 112; or, when the side plate 12 is provided on the second surface 112, the side plate 12 may not be provided on the first surface 111.

[0041] In addition, it should be understood that after the power module is assembled, the first direction is the depth direction of the mounting groove 21. When the first direction is the up and down direction, the mounting groove 21 can be set on the upper surface of the housing 2. At this time, the mounting groove 21 forms an opening on the upper surface of the housing 2.

[0042] like Figure 1 As shown, in one embodiment, in the third direction, the base plate 11 has a first insulating portion 113 and a second insulating portion 114 that are in contact; the side plate 12 is connected to the first insulating portion 113, wherein both the first direction and the second direction intersect the third direction, and further, both the first direction and the second direction are perpendicular to the third direction. Figure 1 and Figure 2 In the directions shown, the third direction is parallel to the Y-axis, and the third direction can be the length direction of the base plate 11.

[0043] The first insulating part 113 and the second insulating part 114 are arranged sequentially along a third direction.

[0044] In practical scenarios, the parts of the structure or device that need to be electrically isolated from the sidewall of the mounting groove 21 (or the parts of the structure or device that require a high degree of electrical isolation from the sidewall of the mounting groove 21) can be disposed on the first insulating part 113, while the parts of the structure or device that do not need to be electrically isolated from the sidewall of the mounting groove 21 (or the parts of the structure or device that require a low degree of electrical isolation from the sidewall of the mounting groove 21) can be disposed on the second insulating part 114. This can reduce the material cost and weight of the insulating sheet 1 while ensuring the electrical isolation effect between the conductive component and the housing 2.

[0045] In addition, after the power module is assembled, the width direction of the base plate 11 can be the width direction of the mounting slot 21, and the length direction of the base plate 11 can be the length direction of the mounting slot 21.

[0046] like Figure 1 As shown, in one embodiment, a first limiting structure 13 is provided on the first surface 111. The first limiting structure 13 is used to cooperate with the first limiting part 22 on the side wall of the mounting groove 21 to limit the relative position of the base plate 11 relative to the housing 2 in a third direction. Wherein, in Figures 1 to 3 and Figure 1 In the example shown, the first limiting structure 13 can be a protruding structure, and the first limiting part 22 can be a concave structure. The protruding structure is located inside the concave structure, and in the third direction, the two sides of the protruding structure can respectively abut against the two side walls of the concave structure, thereby limiting the relative position of the base plate 11 and the shell 2.

[0047] Of course, in other embodiments, the first limiting structure 13 may be configured as a concave structure and the first limiting part 22 may be configured as a convex structure.

[0048] In addition, in the first direction (i.e., the depth direction of the mounting groove 21), the recessed structure extends to the bottom surface of the mounting groove 21, and the recessed structure can also extend to the upper surface of the housing 2, so that the corresponding area of ​​the conductive component can also be arranged in the recessed structure.

[0049] like Figure 3 As shown, in one embodiment, the first limiting structure 13 is disposed on the second insulating part 114; at this time, the first limiting structure 13 is offset from the side plate 12 so as to generate interference.

[0050] Additionally, along the direction from the second surface 112 to the first surface 111, the first limiting structure 13 protrudes from the side plate 12 connected to the first surface 111.

[0051] The first limiting structure 13 and the base plate 11 can be an integral structure, and the two can be located on the same flat plate. This makes it easier to install the insulating sheet 1.

[0052] like Figure 1 As shown, in one embodiment, in the third direction, the base plate 11 has a third surface 115 and a fourth surface 116 disposed opposite to each other; a second limiting structure 14 is provided on the third surface 115, which is used to cooperate with a second limiting part 23 on the side wall of the mounting groove 21 to limit the relative position of the base plate 11 relative to the housing 2 in the second direction. This makes it easier to install the insulating sheet 1 in a suitable position in the mounting groove 21.

[0053] In one embodiment, the second limiting structure 14 is a groove that penetrates the base plate 11 along a first direction. In this case, the first limiting part 22 is a boss provided on the side wall of the mounting groove 21. After assembly, the boss is located within the groove. It should be understood that the groove can also be considered as a structure on the base plate 11 used to avoid the boss.

[0054] like Figure 1 As shown, in one embodiment, a clearance notch 15 is provided on the fourth surface 116, the clearance notch 15 penetrates the bottom plate 11 along the first direction and extends to the second surface 112.

[0055] After assembly, the clearance notch 15 is aligned with the corresponding window 24 on the side wall of the mounting slot 21 to prevent the base plate 11 from adversely affecting the function of the window 24. The window 24 may penetrate the side wall of the mounting slot 21 along a third direction. After the power module is assembled, the corresponding cables electrically connected to conductive components can exit the mounting slot 21 through the window 24.

[0056] like Figure 1 As shown, in one embodiment, the base plate 11 is provided with heat dissipation holes 16, and heat dissipation components are installed in the heat dissipation holes 16; the heat dissipation holes 16 penetrate the base plate 11 along a first direction. After assembly, the heat dissipation components are installed in the heat dissipation holes 16 and contact the housing 2, so that the heat in the housing 2 (i.e., in the mounting groove 21) can be quickly transferred out through the housing 2.

[0057] In one embodiment, multiple heat dissipation holes 16 are provided, and the heat dissipation holes 16 are spaced apart from each other; a heat dissipation component can be installed in each mounting hole. Of course, in other embodiments, only one heat dissipation hole 16 may be provided.

[0058] like Figure 1 As shown, in one embodiment, the base plate 11 is provided with a wire-passing hole 17, which penetrates the base plate 11 along a first direction and can be used to allow corresponding conductive wires to pass through the base plate 11. Furthermore, multiple wire-passing holes 17 are provided, and each wire-passing hole 17 is spaced apart from the others. Of course, in other embodiments, only one wire-passing hole 17 may be provided.

[0059] like Figure 1 As shown, in one embodiment, the base plate 11 is also provided with a connecting hole 18, which penetrates the base plate 11 along the first direction. Bolts and other connecting parts can pass through the connecting hole 18 through the base plate 11 and engage with the corresponding threaded hole on the housing 2 to fix the insulating sheet on the housing 2.

[0060] The number of connection holes 18 can be multiple and spaced apart.

[0061] Alternatively, connection holes 18 can be provided at other locations of the insulating sheet 1. For example, the first limiting structure 13 is also provided with connection holes 18, and the connection holes 18 penetrate the first limiting structure 13 along the first direction.

[0062] like Figure 1 As shown, the third surface 115 is also provided with a connecting portion 19, which is a protrusion. The connecting portion 19 is also provided with a connecting hole 18, which penetrates the connecting portion 19 along the first direction. In addition, multiple connecting portions 19 may be provided and are spaced apart on both sides of the second limiting structure 14 along the second direction.

[0063] In one embodiment, the base plate 11, the first limiting structure 13, and the connecting portion 19 may be located on the same flat plate. During production, the base plate 11, the first limiting structure 13, and the connecting portion 19 can be obtained by cutting a flat plate.

[0064] This utility model embodiment also provides a power module, which includes a housing 2, conductive components, and an insulating sheet 1 as described in any of the above embodiments; the housing 2 has a mounting groove 21, and the insulating sheet 1 and the conductive components are both installed in the mounting groove 21; the bottom plate 11 is disposed between the bottom surface of the mounting groove 21 and the conductive components, and the side plate 12 is disposed between the side surface of the mounting groove 21 and the conductive components.

[0065] The conductive component can be a control board, which includes a circuit board and corresponding devices electrically connected to the circuit board. When the power module is used in a vehicle, the conductive component is electrically connected to the battery. Furthermore, the conductive component can be an existing design.

[0066] In one embodiment, the power module further includes a heat dissipation component, such as a ceramic plate, which, after assembly, is installed within the heat dissipation hole 16 and can contact the housing 2 and the conductive component to quickly transfer the heat generated by the conductive component to the housing 2. The conductive component may have a corresponding MOSFET, which generates a large amount of heat during operation and can contact the heat dissipation component to transfer the generated heat to the housing 2. Alternatively, the heat dissipation component can employ an existing design.

[0067] In one embodiment, the power module also has a housing, and the surface of the housing 2 with the mounting groove 21 is connected to the housing, and the two enclose each other to form a mounting cavity, in which the conductive components, the insulating sheet 1 and the heat dissipation components are all located.

[0068] like Figure 1 Figure 3As shown, in one embodiment, the power module further includes a transformer 3. The bottom surface of the mounting slot 21 is provided with a mounting hole 25. The transformer 3 is installed in the mounting hole 25, and the conductive wires of the transformer 3 pass through the base plate 11 and connect to the conductive components. By placing the transformer 3 and the conductive components on opposite sides of the base plate 11, the electrical isolation between them can be improved.

[0069] In addition, the transformer 3 can be installed in the mounting hole 25 by potting glue, which can fix the transformer 3 in the mounting hole 25.

[0070] In one embodiment, the housing 2, the conductive components, and the aforementioned insulating sheet 1 are actually related components of the charging and discharging unit of the power module. When charging the vehicle, the external power source (such as mains power) can be transformed by the transformer 3 and then used to charge the battery through the conductive components; when using the vehicle to charge external devices, the battery is transformed by the transformer 3 and then output to the external device.

[0071] In addition, the housing 2, conductive components, heat dissipation components, transformer 3, and box can all be existing power modules. In this case, the power module of this application is equivalent to simply replacing the insulating sheet 1 in the existing charging and discharging unit with the insulating sheet 1 of this application.

[0072] This utility model embodiment also provides a vehicle that includes the power module described in any of the above embodiments.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
