Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle parts, in particular to an electric vehicle controller and an electric vehicle. Background Art

[0002] As a core component of electric vehicle controllers, their waterproof performance directly impacts the lifespan and safety of the entire vehicle. To improve waterproofing, manufacturers often use rubber gaskets to seal the joints between electrical interface components and the outer casing. This approach places high demands on the rubber gasket assembly process. If the gaskets aren't perfectly sealed during initial installation, even if they achieve a certain degree of waterproofing, they will easily deform and age over time after long-term use, losing their elasticity and causing seal failure, leading to water seepage.

[0003] Therefore, there is an urgent need for a new electric vehicle controller design that can not only ensure good initial waterproof performance, but also take into account the waterproof requirements after long-term use. Utility Model Content

DETAILED DESCRIPTION

[0041] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0042] like Figures 1-6 As shown, the electric vehicle controller provided by this embodiment mainly includes a bottom shell 10 , a printed circuit board assembly 20 , a top cover 30 and at least one side plate 40 .

[0043] The bottom shell 10 has a cavity 11 with at least one end open inside, and the top of the bottom shell 10 has an opening that is connected to the cavity 11. In this way, a first installation area and a second installation area are formed on the top of the bottom shell 10 for accommodating different components.

[0044] A printed circuit board assembly 20 is disposed within cavity 11 and includes connector terminals 21 and an IO port 22. Connector terminals 21 are located in the first mounting area and are used to connect to an external power source or control cable. IO port 22 is located in the second mounting area and is used to exchange signals with other control components of the electric vehicle.

[0045] The top cover 30 is disposed on the first mounting area of ​​the bottom case 10 to protect internal circuit components such as the printed circuit board assembly 20 .

[0046] At least one side panel 40 is provided at the end opening of the cavity 11 to seal the end of the cavity 11 and secure the internal components. The number of side panels 40 corresponds to the number of end openings of the cavity 11, ensuring that both ends of the cavity 11 are sealed when the controller is in use.

[0047] The joints between the bottom housing 10, the IO port 22, and the adjacent side panel 40, as well as the joints between the bottom housing 10, the top cover 30, the connector terminals 21, and the adjacent side panel 40, form sealant grooves filled with sealant. These joints serve as the connection areas between adjacent components. This design effectively prevents moisture and dust from entering the controller, improving product reliability and service life.

[0048] In this embodiment, the sealant has good adhesion and elasticity, and can be filled into the sealant groove in a paste form and solidified in air to form a stable sealing structure.

[0049] After the PCB assembly 20, top cover 30, and side panels 40 are assembled, the sealant can be evenly filled (injected) into the seal groove. Once the sealant cures, a seal structure perfectly conforms to the contours of the seal groove is formed. Compared to traditional rubber gasket seals, this structure is less susceptible to deformation, improving the overall reliability of the controller.

[0050] In this embodiment, the bottom shell 10 is made of aluminum alloy material, specifically, an aluminum shell formed by die casting or extrusion. The use of aluminum can provide good heat dissipation performance and structural strength while ensuring a light overall weight.

[0051] Both the top cover 30 and side panels 40 are made of sheet metal. Sheet metal is typically made from thin steel sheets through processes such as stamping and bending, and features lightweight, high strength, and excellent machining precision. The aluminum shell and sheet metal components ensure sufficient strength for the controller housing while facilitating processing and assembly.

[0052] By using an aluminum shell as the bottom housing 10 and sheet metal components for the top cover 30 and side panels 40, this embodiment of the electric vehicle controller achieves a lightweight design while ensuring strength and heat dissipation performance. Furthermore, the all-metal structure of the aluminum shell base and sheet metal top cover and side panels enhances the controller's radiation immunity.

[0053] In this embodiment, the adhesive groove formed at the junction of the bottom shell 10, the IO port 22 and the adjacent side panel 40 is the first adhesive groove 51. The first adhesive groove 51 extends along the outer contour of the IO port 22 and includes:

[0054] The intersections between the IO port 22 and the top of the bottom shell 10, and the intersections between the IO port 22 and the adjacent side panels 40 are interconnected to form a first glue groove 51 connected end to end.

[0055] In this embodiment, the adhesive groove formed at the joint of the bottom shell 10, the top cover 30, the connector terminal 21 and the adjacent side plate 40 is the second adhesive groove 52. The outline of the second adhesive groove 52 includes:

[0056] The intersections between the top cover 30 and the top of the bottom shell 10, the intersection between the top cover 30 and the side panel 40, and the intersections between the connector terminals 21 and the top cover 30, the top of the bottom shell 10, and the side panel 40 are interconnected to form a second glue groove 52 that is connected end to end.

[0057] In this embodiment, if Figure 4 As shown, the area where the connector terminals 21 are located is the first mounting area, which not only accommodates the connector terminals 21 but also includes the top cover 30. The area where the IO port 22 is located is the second mounting area. These two areas are spaced apart from each other.

[0058] In one embodiment, to improve the connection stability between the top cover 30 and the bottom shell 10, barb structures 60 are provided on opposite sides of the top cover 30. Accordingly, a slot 70 that cooperates with the barb structures 60 is provided on the top opening edge of the bottom shell 10.

[0059] The barb structure 60 can be an elastic clip protruding outward from the side of the top cover 30, with its end bent downward to form a barb. The slot 70 is a groove defined inside the opening edge of the bottom shell 10. When the top cover 30 is in place, the barb structure 60 is completely immersed in the slot 70.

[0060] The snap-fit ​​design of the barb and the slot 70 can effectively limit the up and down movement of the top cover 30. At the same time, the snap-fit ​​design is also easy to disassemble and convenient for later maintenance.

[0061] In this embodiment, if Figure 2 and Figure 3 As shown, the barb structures 60 are specifically provided on the front and rear sides of the top cover 30. Correspondingly, the latching slots 70 are specifically provided at the edges of the two inner walls of the top opening of the bottom shell 10.

[0062] In one embodiment, two connector terminals 21 are provided, which are respectively arranged at opposite ends of the top cover 30. The opposite ends of the top cover 30 are provided with abutment structures 80. The opposite ends here are the left end and the right end.

[0063] This abutment structure 80 can be a protrusion or reinforcement rib extending downwardly from the end of the top cover 30. When the top cover 30 is installed in place, the abutment structure 80 will abut against the top of the adjacent connector terminal 21.

[0064] The purpose of this design is to form a continuous seam between the top cover 30 and the connector terminals 21, which is a part of the second glue groove 52. By injecting sealant into this glue groove, moisture can be effectively prevented from penetrating into the controller from around the connector terminals 21.

[0065] The presence of the abutting structure 80 not only forms a glue groove, but also plays a certain role in fixing the plug-in terminal 21, thereby improving the stability of the overall structure.

[0066] In one embodiment, the printed circuit board assembly 20 includes a main circuit board 23 and a power tube 24. The power tube 24 is mounted on the main circuit board 23. The IO ports 22 and the connector terminals 21 are arranged on the main circuit board 23 at intervals.

[0067] In this embodiment, two connector terminals 21 are located on the left and right ends of the main circuit board 23, specifically above the left and right ends. This left-right layout facilitates external wiring, allowing cables to be routed from both sides of the controller, avoiding congestion and interference caused by cables being concentrated on one side.

[0068] In one embodiment, the bottom case 10 includes a bottom plate 12 , which is the main body of the bottom case 10 and is used to support and fix the printed circuit board assembly 20 therein.

[0069] Extension structures 13 are provided on the front and rear sides of the bottom plate 12. The extension structures 13 extend upward from the bottom plate 12, and a first mounting area is formed between the tops thereof for mounting the top cover 30 and the connector terminals 21.

[0070] A channel 14 is provided at the top of one side of the extension structure 13 (either the front or rear side) and communicates with the cavity 11. This channel 14 extends from one end of the extension structure 13 along its length to the other end, forming a second mounting area for mounting the IO port 22.

[0071] This design allows the IO port 22 to be inserted into the second mounting area along with the main circuit board. Specifically, during assembly, the IO port 22, as part of the printed circuit board assembly 20, can be inserted into the second mounting area along the channel 14 along with the main circuit board 23. This design simplifies the assembly process.

[0072] By providing the partially extended channel 14 , the partial integrity of the side extension structure 13 is retained, thereby improving the overall structural strength.

[0073] Through the design of the extension structures 13 on both sides, the installation areas of the connector terminals 21 and the IO ports 22 are clearly defined, making the assembly process more standardized and efficient. It is only necessary to insert the printed circuit board assembly 20 into the bottom shell 10 along the extension direction of the first installation area and the second installation area.

[0074] In this embodiment, the extension structure 13 provided with the channel is the rear extension structure 13. The slots 70 of the top opening edge of the bottom shell 10 are specifically provided on adjacent side surfaces of the tops of the two extension structures 13.

[0075] In this embodiment, partial extension means that the length of the channel 14 is shorter than the length of its corresponding extension structure 13. This design does not require that both side panels 40 on both sides be combined with the IO port 22 and sealant be provided between them.

[0076] In this embodiment, the extension structures 13 on the front and rear sides and the bottom plate 12 at the bottom thereof together form a cavity 11 with openings at the top, left end, and right end.

[0077] In this embodiment, if Figure 2 As shown, the front extension structure 13 is specifically an aluminum shell portion extending upward. The rear extension structure 13 is specifically an aluminum shell portion extending upward, then extending toward the front side, and finally extending upward again.

[0078] In this embodiment, the top opening of the bottom housing 10 overlaps with the top opening of the cavity 11. Specifically, there are two openings at the top of the cavity 11, spaced apart from each other. The front opening accommodates the connector terminals 21 and the top cover 30, while the rear opening accommodates the IO port 22.

[0079] In one embodiment, the cavity 11 of the controller is designed with openings at both ends, and is equipped with two side panels 40 to close the left and right ends respectively.

[0080] The contact surface between the side plate 40 and the top of the bottom shell 10 can be designed with a groove (not shown in the drawings) and filled with sealant to improve the waterproof performance.

[0081] In this embodiment, the side panels 40 and the bottom shell 10 can be fixed with screws to facilitate installation and disassembly.

[0082] In other embodiments, the cavity 11 of the controller is designed to be closed at the left end and open at the right end, and is equipped with a side panel 40. The contours of the first glue groove 51 and the second glue groove 52 remain unchanged.

[0083] Based on any of the above embodiments, this embodiment further provides an electric vehicle. The electric vehicle integrates the electric vehicle controller of any of the above embodiments. The controller's bottom housing 10, top cover 30, and side panels 40 are all made of metal. A sealant and a sealant groove are used on the top of the controller to form a sealing structure, allowing the controller to better adapt to rainy environments and improving the safety of the electric vehicle.

[0084] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
