[0002] A controller is an electronic device that can be used to receive and process signals and manage power distribution. With the development of electric vehicle technology, the controller, as one of the important control components, realizes the control of various structures of electric vehicles.

[0003] The controller includes a box body and internal components. To facilitate disassembly, the box body includes a detachable upper cover and a lower shell. During installation, the internal components are placed inside the lower shell. The upper cover is connected with a buckle, and the upper cover is installed on the lower shell through the buckle. This can provide protection for the internal components and prevent the internal components from being affected by dust or liquid and causing malfunction.

[0004] The box body is usually made of plastic material, and the buckle is integrally formed with the upper cover through an injection molding process. However, the box body made of plastic material has poor thermal conductivity, which may cause the heat generated by the internal components during use to accumulate inside the box body, thereby affecting the normal use of the internal components. If the box body material is replaced with metal material, since the buckle cannot be connected to the upper cover through the injection molding process, the upper cover and the lower shell need to be connected by bolts, making the installation more cumbersome and not conducive to the quick connection of the upper cover and the lower shell. There may also be a gap between the upper cover and the lower shell, making the box body waterproof poor. External liquids can easily enter the lower shell through the gap and contact the internal components, causing internal components to short-circuit or even fail. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] See also Figure 1-Figure 3 The utility model provides a controller, including a box body 1, an internal component 2 and a connecting member 3. The box body 1 includes an upper cover 11 and a lower shell 12. The upper cover 11 is covered on the lower shell 12; the internal component 2 is arranged inside the lower shell 12, and the lower shell 12 is filled with a potting glue (not shown in the figure), and at least part of the components of the internal component 2 are potted in the potting glue; the connecting member 3 is integrally formed with the upper cover 11, and at least part of the connecting member 3 is fixed in the potting glue, and is used to limit the upper cover 11 and the lower shell 12. Among them, the upper cover 11 and the lower shell 12 are made of aluminum alloy material.

[0034] It should be noted that after the internal component 2 is fixed inside the lower shell 12, the liquid potting glue is filled into the lower shell 12, and the upper cover 11 is placed on the lower shell 12 when the potting glue is not completely solidified, so that the connecting member 3 is at least partially immersed in the potting glue. When the potting glue is solidified, the position of the connecting member 3 is restricted, thereby realizing the connection between the upper cover 11 and the lower shell 12.

[0035] In this way, by providing an integrally formed connector 3, the connector 3 is directly combined with the potting glue to limit the position of the connector 3, and then the upper cover 11 is connected to the lower shell 12, which can improve the installation efficiency of the upper cover 11 and the lower shell 12; filling the lower shell 12 with potting glue can not only contact the internal component 2 and transfer the heat generated by the internal component 2 when working, but also fix the position of the internal component 2 and the connector 3, and prevent the internal component 2 from contacting the liquid, thereby improving the waterproof performance; and the box body 1 made of metal material has good thermal conductivity, and can promptly transfer the heat transferred by the potting glue to the outside, thereby avoiding the formation of heat accumulation inside the box body 1.

[0036] It should be noted that the internal components 2 provided in the embodiment of the present application include capacitors, connectors, power tubes and other devices of the controller, which are not limited in the present application.

[0037] It is understandable that the upper cover 11 and the lower shell 12 can be made of the same material or different materials. The materials of the upper cover 11 and the lower shell 12 can be adjusted according to actual needs, and can also be other metal materials with good thermal conductivity, which can achieve the purpose of transferring the heat generated by the internal components 2 to the outside. No further examples are given here.

[0038] See also Figure 2 and Figure 3 In some embodiments, a plurality of connectors 3 are provided, and the plurality of connectors 3 are spaced apart in the circumferential direction of the upper cover 11. Among them, four connectors 3 are provided, and the four connectors 3 are symmetrically arranged at the two end edges of the upper cover 11 in the length direction.

[0039] In this way, multiple connecting parts 3 are arranged at intervals in the circumferential direction of the upper cover 11 and connected to the solidified potting glue, which can further enable the upper cover 11 to be stably covered on the lower shell 12, avoiding the risk of deviation or even falling off due to unstable connection between the upper cover 11 and the lower shell 12. The upper cover 11 and the potting glue can protect the internal components 2, prevent external liquids from contacting the internal components 2 and causing malfunctions of the internal components 2, thereby improving the safety and waterproofness of the controller.

[0040] It is understandable that the number, shape and location of the connecting members 3 can be adjusted according to actual conditions, and the connecting members 3 can also be arranged on both sides of the upper cover 11 in the length direction, which will not be elaborated here.

[0041] See also Figure 2 and Figure 3In some embodiments, the connector 3 includes a first portion 31 and a second portion 32 connected at an angle, the first portion 31 is connected to the upper cover 11, and the second portion 32 is connected to an end of the first portion 31 away from the upper cover 11. In this embodiment, one first portion 31 is connected to a corresponding second portion 32, the second portion 32 is integrally formed with the first portion 31, and the second portion 32 is located at the first portion 31 facing the internal component 2 (see Figure 1 ) on one side.

[0042] It should be noted that when the upper cover 11 is placed on the lower shell 12 , the second portion 32 is completely immersed in the potting glue.

[0043] In this way, the second part 32 is set at an angle with the first part 31, so that the first part 31 and the second part 32 are combined with the potting glue in different directions and form an interlocking structure with the potting glue, which can further enhance the connection stability between the upper cover 11 and the lower shell 12, so that after the upper cover 11 is connected to the lower shell 12, it is not easy to cause position displacement with the lower shell 12 due to external forces, and the box body 1 can stably protect the internal components 2 and transfer the heat inside the box body 1 to the outside, thereby maintaining good heat dissipation performance.

[0044] See also Figure 2 and Figure 3 In some embodiments, the first portion 31 is vertically disposed with the upper cover 11, and the second portion 32 is vertically disposed with the first portion 31. The first portion 31 and the second portion 32 are both rectangular plate-shaped structures, and the first portion 31 and the second portion 32 form a buckle structure with an L-shaped longitudinal section.

[0045] In this way, when the upper cover 11 and the lower shell 12 are both made of metal materials, materials to be processed into the connecting part 3 can be reserved during the stage of stamping the upper cover 11, and the connecting part 3 formed integrally with the upper cover 11 can be formed through processes such as bending, so that the upper cover 11 made of metal material can be quickly assembled to the lower shell 12 by combining the connecting part 3 with the potting glue, and the box body 1 has good thermal conductivity to avoid the heat generated by the internal components 2 when working to accumulate inside the lower shell 12.

[0046] It can be understood that the angle between the first part 31 and the upper cover 11, and the angle between the second part 32 and the first part 31 can be adjusted according to actual needs, and can also be tilted, so that the first part 31 and the second part 32 can be combined with the potting glue to form an interlocking structure; the first part 31 and the second part 32 can also be a wavy plate structure, and are not limited to a flat plate structure. The shape and quantity of the first part 31 and the second part 32 can be adjusted according to actual needs, and no more examples are given here.

[0047] Furthermore, multiple groups of the first part 31 and the second part 32 can also be arranged in sequence along the height direction of the lower shell 12 to further enhance the connection strength between the connector 3 and the potting glue. The shapes of the first part 31 and the second part 32 can be adjusted according to actual needs, and no more examples are given here.

[0048] See also Figure 1 and Figure 2 In some embodiments, a receiving hole 111 is formed on the upper cover 11 for receiving the internal component 2, and the controller further comprises a waterproof boss 4, which is arranged at the edge of the receiving hole 111. In this embodiment, the outer wall of the waterproof boss 4 is smoothly connected to the side of the upper cover 11 away from the lower shell 12, and the shape of the waterproof boss 4 is adapted to the shape of the receiving hole 111.

[0049] In this way, the receiving hole 111 can connect the exposed part of the internal component 2 to the upper cover 11, which is convenient for the staff to operate; when liquid is spilled on the upper cover 11, the waterproof boss 4 can block the liquid from entering the lower shell 12 through the receiving hole 111, avoiding the liquid from contacting the internal component 2 and causing a short circuit failure of the internal component 2, thereby improving the waterproof performance of the box body 1.

[0050] See also Figure 1 In some embodiments, the receiving hole 111 includes a first receiving hole 1111 and a second receiving hole 1112, and the internal component 2 includes a signal terminal 21 and a power terminal 22, the signal terminal 21 is inserted into the first receiving hole 1111, and the power terminal 22 is inserted into the second receiving hole 1112. There are two signal terminals 21, and the two signal terminals 21 are respectively arranged at two ends in the length direction of the lower shell 12, and the ends of the power terminal 22 and the signal terminal 21 located in the lower shell 12 are connected to the potting glue, and the ends of the power terminal 22 and the signal terminal 21 with ports are located outside the upper cover 11.

[0051] In this way, connecting the signal terminal 21 and the power terminal 22 with the potting glue can not only fix the positions of the signal terminal 21 and the power terminal 22, but also enable the external circuit to be connected to the power terminal 22 or the signal terminal 21 through the interface and transmit electrical energy or electrical signals, so that the controller can regulate the structure connected to it.

[0052] See also Figure 2 and Figure 4 In some embodiments, the waterproof boss 4 includes an abutment portion 41 extending toward the interior of the lower shell 12 , the abutment portion 41 is used to abut with the internal component 2 in a limited position, and the height of the abutment portion 41 is less than the height of the first portion 31 .

[0053] Among them, the abutment portion 41 is an annular structure whose shape is adapted to the waterproof boss 4. The abutment portion 41 and the waterproof boss 4 are integrally formed with the upper cover 11 by stamping. The side wall of the abutment portion 41 abuts against the side wall of the internal component 2. Further, the side wall of the abutment portion 41 abuts against the side wall of the power terminal 22 or the signal terminal 21 respectively.

[0054] In this way, by setting the abutment portion 41 so that it is in close contact with the internal component 2, the gap between the waterproof boss 4 and the internal component 2 can be reduced, making it difficult for liquid to enter the lower shell 12 through the accommodating hole 111 and contact the internal component 2, thereby improving the waterproof performance and overall strength of the box body 1.

[0055] See also Figure 2 In some embodiments, the potting glue is connected to at least part of the abutting portion 41 to limit the abutting portion 41. When the upper cover 11 is connected to the lower shell 12, the top surface of the potting glue abuts against the side of the upper cover 11 facing the lower shell 12, so that the abutting portion 41 is completely immersed in the potting glue.

[0056] In this way, the upper cover 11 is connected to the lower shell 12 while the abutting portion 41 abuts against the internal component 2, so that the assembly of the box body 1 can be quickly completed and a waterproof structure can be formed. After the potting glue solidifies, it can limit the position of the abutting portion 41, so that the upper cover 11 and the lower shell 12 are further stably connected, and it can also improve the waterproof performance of the waterproof boss 4 to avoid contact between the internal component 2 and the liquid; the heat generated by the internal component 2 during operation can be transferred to the abutting portion 41 through the potting glue, and then transferred to the outside through the abutting portion 41, thereby enhancing the thermal conductivity of the upper cover 11 and improving the thermal conductivity efficiency of the box body 1.

[0057] It is understandable that the height of the potting glue can be adjusted according to actual needs, as long as it can be connected to both the connecting member 3 and the abutting portion 41 , and no further details are given here.

[0058] See also Figure 5 and Figure 6 In some embodiments, the box body 1 further includes a supporting portion 13 , which is disposed in the lower shell 12 and is used to support the upper cover 11 .

[0059] Furthermore, the lower shell 12 includes a first side plate 121 and a second side plate 122, the first side plate 121 and the second side plate 122 are detachably connected, the support portion 13 is fixedly arranged on the inner wall of the second side plate 122, the first side plate 121 and the second side plate 122 are connected by bolts, and the support portion 13 is provided with a connecting groove 131 corresponding to the bolt.

[0060] In this embodiment, two first side panels 121 and two second side panels 122 are provided, the two first side panels 121 constitute the two end panels of the lower shell 12 in the length direction, the two second side panels 122 constitute the two side panels of the lower shell 12 in the length direction, and the lower shell 12 also includes a bottom plate 123, and the bottom plate 123 is respectively connected to the first side panel 121 and the second side panel 122, so that the upper cover 11, the first side panel 121, the second side panel 122, and the bottom plate 123 jointly form a cavity for accommodating the internal component 2.

[0061] In this way, when the upper cover 11 is connected to the lower shell 12 via the connector 3 and the potting glue, the support portion 13 can provide stable support for the upper cover 11 , thereby improving the overall structural strength of the box body 1 .

[0062] Furthermore, the support portion 13 is arranged on the side of the second side plate 122 facing the upper cover 11, and the length direction of the support portion 13 is parallel to the length direction of the second side plate 122, the length direction of the connecting groove 131 is parallel to the length direction of the support portion 13, and the connecting groove 131 is arranged through the support portion 13, and threads are provided at both ends of the connecting groove 131, so that the bolt is connected to the support portion 13 through the connecting groove 131 to connect the first side plate 121 and the second side plate 122.

[0063] See also Figure 5 In some embodiments, the lower shell 12 is further provided with a heat dissipation slot 124 . In this embodiment, a plurality of heat dissipation slots 124 are provided, and the plurality of heat dissipation slots 124 are arranged side by side on the bottom surface of the base plate 123 , and the length direction of the heat dissipation slot 124 is parallel to the length direction of the base plate 123 .

[0064] Thus, the heat dissipation slots 124 are provided on the bottom plate 123 to increase the heat conduction area, so that the heat inside the lower shell 12 is transferred to the outside through the heat dissipation slots 124 , thereby improving the heat dissipation efficiency.

[0065] It is understandable that the number and position of the heat dissipation slots 124 can be adjusted according to actual needs, and the heat dissipation slots 124 can also be opened on the first side plate 121 and the second side plate 122, which will not be described in detail here.

[0066] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
