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

[0041] This embodiment provides an electric vehicle, including a vehicle body and a controller assembly, wherein the controller assembly is fixedly mounted on the vehicle body. Figure 1-Figure 6 As shown, the controller assembly includes a control board 100, a front shell 200 and a bottom shell 300. The front shell 200 and the bottom shell 300 are arranged to form an inner cavity for accommodating the control board 100. The control board 100 is provided with a plurality of wiring terminals 110 for electrically connecting external devices. The wiring terminals 110 include power terminals, phase terminals and signal terminals.

[0042] Further, such as Figure 1-Figure 6 As shown, the face shell 200 is provided with a yield structure for the connecting terminal 110 to pass through, and the inner cavity is poured with potting glue to form an integrated glue sealing part 400, which blocks the gap between the yield structure and the connecting terminal 110 and the gap between the face shell 200 and the bottom shell 300, thereby preventing external moisture from penetrating through the gap between the yield structure and the connecting terminal 110 or the gap between the face shell 200 and the bottom shell 300.

[0043] Specifically, the controller component provided in the present embodiment passes through the yield structure on the face shell 200 through the connection terminal 110 on the control board 100 to connect to an external power line or signal line, and forms an integrated glue sealing part 400 by pouring potting glue into the inner cavity formed by the face shell 200 and the bottom shell 300. The glue sealing part 400 is used to achieve sealing between the yield structure of the face shell 200 and the connection terminal 110, and between the face shell 200 and the bottom shell 300. Compared with the conventional glue dispensing process and sealing ring sealing method, the controller component provided in the present embodiment can achieve comprehensive sealing and waterproofing through only one glue pouring, and the process is simpler, which simplifies the production process and is conducive to improving production efficiency.

[0044] In this embodiment, if Figure 1-Figure 6 As shown, the clearance structure includes a clearance hole 201, which is arranged around the periphery of the connection terminal 110. Specifically, there are three connection terminals 110 on the control board 100, and three clearance holes 201 are correspondingly arranged. The three connection terminals 110 are passed through the three clearance holes 201 one by one.

[0045] For example, Figure 2-Figure 4As shown, the inner wall of the giving way structure extends downward to form a lower extension portion 210, and the lower extension portion 210 extends downward into the glue seal portion 400, and the glue seal portion 400 blocks the gap between the lower extension portion 210 and the connection terminal 110. Specifically, by providing the lower extension portion 210, the depth of the inner wall of the giving way hole 201 extending downward is extended, that is, the depth of the gap between the giving way hole 201 and the connection terminal 110 is increased, and the depth of the glue seal portion 400 filling in the gap is also greater. Even if there is a certain fluctuation in the filling depth of the glue seal portion 400, the sealing effect can be ensured, thereby improving the reliability of the sealing.

[0046] For example, Figure 2-Figure 4 As shown, the lower surface of the face shell 200 is a sealing surface 220, a receiving groove for accommodating the control board 100 is formed in the bottom shell 300, an overlapping step 310 is provided on the inner wall of the bottom shell 300, the sealing surface 220 is overlapped above the overlapping step 310, and the glue sealing part 400 blocks the gap between the sealing surface 220 and the bottom shell 300.

[0047] When installing the controller assembly, first install the control board 100 in the bottom shell 300, then pour potting glue into the receiving groove to form a glue-sealed portion 400. Before the glue-sealed portion 400 solidifies, install the face shell 200 on the bottom shell 300 so that the lower extension 210 is inserted into the glue-sealed portion 400. The glue-sealed portion 400 fills the gap between the sealing surface 220 and the overlapping step 310 and the gap between the side edge of the face shell 200 and the inner wall of the bottom shell 300, thereby achieving comprehensive sealing and waterproofing among the face shell 200, the bottom shell 300 and the terminal block 110, and the production process is simple.

[0048] Further, such as Figure 4 As shown, the upper surface of the glue sealing portion 400 is a glue cover 410 , and the height of the glue cover 410 is higher than the bottom end height of the lower extension portion 210 , thereby ensuring a waterproof sealing effect between the face shell 200 and the connection terminal 110 .

[0049] Further, such as Figure 4 As shown, the sealing surface 220 is flush with the glue cover 410, that is, the lower surface of the face shell 200 is flush with the top surface of the glue sealing portion 400, and the bottom end height of the lower extension portion 210 is also lower than the height of the sealing surface 220, which ensures that the glue sealing portion 400 can reliably seal the gap between the face shell 200 and the bottom shell 300, and can also ensure the insertion depth of the lower extension portion 210, ensuring that the glue sealing portion 400 can reliably seal the gap between the terminal 110 and the face shell 200.

[0050] In another embodiment of the present invention, Figure 7As shown, the yielding structure further includes a yielding groove 202, and the opening side of the yielding groove 202 is arranged toward the inner peripheral wall of the bottom shell 300. One side of the connection terminal 110 is arranged opposite to the inner peripheral wall of the bottom shell 300, and the glue sealing part 400 directly blocks the gap between the inner peripheral wall of the bottom shell 300 and the connection terminal 110. Of course, in some other embodiments of the utility model, the yielding structure can also be set as the yielding groove 202.

[0051] Exemplarily, the sealant 400 is formed of a heat-conducting potting sealant. A plurality of electronic components 120 are disposed on the control board 100. The plurality of electronic components 120 include capacitors and MOS tubes, such as Figure 2 As shown, the seal portion 400 covers a part or all of the electronic components 120, and the control board 100 and the electronic components 120 are thermally connected to the surface shell 200 and the bottom shell 300 through the seal portion 400 to accelerate the heat dissipation of the control board 100 and the electronic components 120 thereon to the outside, thereby ensuring the stable performance of the controller assembly.

[0052] Exemplarily, the glue sealing part 400 can be formed by thermally conductive potting glue of the type such as organic silicon thermal conductive glue, epoxy resin AB glue, acrylic thermal conductive glue, polyurethane thermal conductive glue, etc.

[0053] Exemplarily, the surface shell 200 is made of heat-conducting metal materials such as aluminum alloy and stainless steel.

[0054] Exemplarily, the bottom shell 300 is made of a heat-conducting metal material such as aluminum alloy, stainless steel, or cast iron, and the seal portion 400 extends between the inner side wall and the bottom wall of the control board 100 and the bottom shell 300 to thermally connect the control board 100 and the bottom shell 300, and heat dissipation fins 320 are provided at the bottom of the bottom shell 300 to increase the contact area between the bottom shell 300 and the external air and improve the efficiency of the bottom shell 300 in dissipating heat to the outside world.

[0055] For example, Figure 2 , Figure 4-Figure 6 As shown, a plurality of electronic components 120 and wiring terminals 110 are arranged on the upper side of the control board 100, and the surface shell 200 forms a accommodating cavity 203, in which the electronic components 120 are accommodated, and a yielding structure is arranged on the side of the accommodating cavity 203. The surface shell 200 is highly adaptable to the control board 100, and the accommodating cavity 203 and the yielding structure are arranged correspondingly to the electronic components 120 and the wiring terminals 110 on the control board 100, so that the structure is more compact, the overall size of the controller assembly is reduced, and miniaturization design is conducive.

[0056] Exemplarily, the face shell 200 is made of metal sheet, the giving way structure is formed by stamping the metal sheet, and the accommodating cavity 203 is formed by stamping and / or stretching the metal sheet. Compared with molding by die-casting, the face shell 200 can be set with a thinner wall thickness, thereby reducing material costs.

[0057] Exemplarily, the lower extension portion 210 is formed by a bending process. Specifically, the clearance structure is formed by stamping a metal plate, and then the inner wall of the clearance structure is bent downward to form the lower extension portion 210.

[0058] Exemplarily, the control board 100 includes a PCB and a single chip microcomputer mounted on the PCB, which can load and run a control program to control the motor of the electric vehicle.

[0059] For example, Figure 5 and Figure 6 As shown, locking ears 204 are provided at the four corners of the control board 100 , and connecting holes are provided on the locking ears 204 . The control board 100 is fastened to the lower housing by screws passing through the locking ears.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
