Description

Technical Field

[0001] This application relates to the technical field of electric vehicle controllers, and in particular to a controller housing structure for electric vehicles that is easy to assemble. Background Technology

[0002] Currently, electric vehicle controllers generally adopt... Figure 1 The structure shown has a central section as a whole, with cover plates at both ends. The four corners of the cover plates are fixed to the central section with screws. This structure is cumbersome to disassemble and assemble during maintenance after leaving the factory, and the screws are prone to stripping at the connection between the screws and the central section, which poses a safety hazard to the use of the controller. Utility Model Content

[0003] The purpose of this application is to provide a controller housing structure for electric vehicles that is easy to assemble, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides a controller housing structure for electric vehicles that is easy to assemble, using the following technical solution:

[0005] An easy-to-assemble controller housing structure for electric vehicles includes a top cover, a base, a lower pressure strip, and an upper pressure strip. A square frame is provided on the base, forming an installation chamber. Symmetrical bottom extensions are provided on both sides of the base. The top cover fits over the square frame and has a top extension corresponding to the bottom extensions. A bottom groove is provided at the bottom end of the bottom extension, and a top groove is provided on the surface of the top extension. Both the bottom and top grooves have corresponding locking holes and mounting holes. Mounting holes are symmetrically provided on both sides of the locking holes. A connecting stud is fixed in the middle of the lower pressure strip, and a connecting hole is provided on the upper pressure strip corresponding to the connecting stud. A nut is fitted onto the connecting stud.

[0006] A sealing gasket is provided between the top cover and the base.

[0007] The mounting hole is an oval-shaped hole.

[0008] Preferably, the thickness of the lower pressure strip is greater than the depth of the bottom slot.

[0009] By adopting the above technical solution, when the thickness of the pressure strip is greater than the depth of the slot, the bottom of the controller can be kept out of contact with the frame after the controller is installed on the electric vehicle frame, thereby increasing the heat dissipation area.

[0010] Preferably, the inner wall of the top cover has an annular protrusion, the bottom of which is adhered to a sealing ring, and the top of the square frame can abut against the sealing ring.

[0011] By adopting the above technical solution, the annular protrusion and sealing ring can achieve a secondary sealing effect, ensuring the internal sealing of the top cover and reducing dust pollution.

[0012] Preferably, to facilitate the top cover fitting onto the base, a chamfer is provided at the outer edge of the top of the square frame.

[0013] Preferably, a notch is provided on one side wall of the bottom extension.

[0014] By adopting the above technical solution, the notch is designed to make it easier for workers to pry up the top cover with a screwdriver (because after the sealing gasket has been used for a long time, the top cover and the base may stick together, and it is difficult to pry it off by hand).

[0015] In summary, this application includes at least one of the following beneficial technical effects: the easily assembled controller housing structure for electric vehicles uses upper and lower pressure strips to pull the top cover to the base, and only two connecting studs are needed for fixation. The controller housing is further locked and fixed using the mounting holes connected to the vehicle frame, resulting in good fixation. During maintenance, the controller housing can be disassembled by removing the mounting screws from the vehicle frame, greatly simplifying the disassembly and assembly process.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0022] This application discloses a controller housing structure for electric vehicles that is easy to assemble, referring to... Figure 2-4The system includes a top cover 1, a base 2, a lower pressure strip 3, and an upper pressure strip 4. A square frame 21 is provided on the base 2, forming an installation chamber. Symmetrical bottom extensions 211 are provided on both sides of the base 2. The top cover 1 is fitted onto the square frame 21. To facilitate installation of the top cover 1, a chamfer is provided at the outer edge of the top of the square frame 21. A sealing gasket 5 is provided between the top cover 1 and the base 2. A top extension 12 is provided on the top cover 1 corresponding to the position of the bottom extension 211. The bottom end of the bottom extension 211... A bottom slot 2111 is provided, and a top slot 121 is provided on the surface of the top extension 12. Both the bottom slot 2111 and the top slot 121 are provided with locking holes 6 and mounting holes 7 respectively. Mounting holes 7 are provided symmetrically on both sides of the locking holes 6. In order to facilitate the installation of the controller on the electric vehicle frame, the mounting holes 7 are oval holes. A connecting stud 31 is fixed in the middle of the lower pressure bar 3. A connecting hole 41 is provided on the upper pressure bar 4 at the position of the connecting stud 31. A nut 32 is matched on the connecting stud 31.

[0023] Reference Figure 4 The thickness of the lower pressure strip 3 is greater than the depth of the bottom slot 2111. When the thickness of the lower pressure strip 3 is greater than the depth of the slot, the bottom of the controller can be installed on the electric vehicle frame without contacting the frame, thereby increasing the heat dissipation area.

[0024] Reference Figure 2 and Figure 3 The inner wall of the top cover 1 has an annular protrusion 11, and a sealing ring is adhered to the bottom of the annular protrusion 11. The top of the square frame 21 can abut against the sealing ring.

[0025] The annular protrusion 11 and the sealing ring can achieve a secondary sealing effect, ensuring that the inside of the top cover 1 is sealed and reducing dust contamination.

[0026] Reference Figure 1 and Figure 4 A notch 8 is provided on one side wall of the bottom extension 211. The notch 8 is designed to make it easier for workers to pry up the top cover 1 with a screwdriver (because after the sealing gasket 5 has been used for a long time, the top cover 1 and the base 2 may stick together, and it is difficult to pry them up by hand).

[0027] The implementation principle of the controller housing structure for electric vehicles that is easy to assemble according to the embodiments of this application is as follows:

[0028] During assembly, since the circuit board is installed in the installation chamber, the staff can directly remove and install the circuit board from the top, which is relatively simple. During assembly, simply cover the top cover 1 onto the base 2 and fix the lower pressure strip 3 and the upper pressure strip 4 from both sides with nuts 32. At this time, the top cover 1 can be firmly pressed onto the base 2 to form a whole. When the controller is installed on the electric vehicle frame, the upper pressure strip 4 and the lower pressure strip 3 can be pressed again when it is fixed to the frame through the mounting holes 7 on both sides. This structure not only ensures the overall firmness of the controller, but also simplifies the disassembly and assembly of the controller.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
