Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples.

[0029] Reference below Figure 1-Figure 3 A motor controller 100 according to an embodiment of the present invention is described.

[0030] like Figure 1-Figure 2 As shown, the motor controller 100 according to an embodiment of the present invention includes: a housing 10, an installation space 13 is provided in the housing 10, a plurality of high-voltage devices 16 are provided in the installation space 13, at least two of the plurality of high-voltage devices 16 are electrically connected through a terminal block 15, wherein the housing 10 includes a bottom wall 11 and a side wall 12, the bottom wall 11 and the side wall 12 are connected to define the installation space 13, and at least one of the bottom wall 11 and the side wall 12 is constructed as a capacitor structure 14, the capacitor structure 14 includes a shell part 142 and a capacitor part 141, the capacitor part 141 is connected to the shell part 142 and is integrally injection molded with the shell part 142, and the capacitor part 141 is suitable for weakening and absorbing the peak pulse of the high-voltage device 16.

[0031] Therefore, at least one of the bottom wall 11 and the side wall 12 of the housing 10 is constructed as a capacitor structure 14, so that the capacitor structure 14 can be directly integrated into the housing 10, so that the capacitor structure 14 does not need to occupy the installation space 13, thereby realizing a miniaturized design of the motor controller 100, and when the capacitor part 141 and the shell are integrally injection molded, the housing 10 will also be integrally molded, thereby realizing a lightweight design of the motor controller 100.

[0032] For example, in the related art, the housing 10 of the motor controller 100 is usually made of aluminum alloy die-casting, so that the weight of the motor controller 100 is relatively large, and it will create a burden when reducing energy consumption. The housing 10 of the motor controller 100 in the present application is made of engineering plastic for one-piece injection molding, which can make the weight of the motor controller 100 lighter, thereby realizing a lightweight design of the motor controller 100, reducing costs and helping to reduce energy consumption. At the same time, the capacitor structure 14 arranged in the motor controller 100 in the present application is integrated on the bottom wall 11 or the side wall 12 of the housing 10, so that the capacitor structure 14 will not occupy the installation space 13, which is conducive to the miniaturization design of the motor controller 100.

[0033] It should be noted that the density of the aluminum alloy die casting in the related art is 2.7 kg / mm 3 , while the density of the engineering plastic in this application is 1.4kg / mm 3 Thus, the housing 10 in the present application is about half lighter than the housing 10 formed by aluminum alloy die casting at the same size, which can well realize the lightweight design of the motor controller 100 and effectively reduce the cost.

[0034] According to the motor controller 100 of the embodiment of the present invention, at least one of the bottom wall 11 or the side wall 12 of the outer shell 10 is constructed as a capacitor structure 14, so that the capacitor structure 14 does not occupy the installation space 13, and the miniaturized design of the motor controller 100 can be achieved. At the same time, the integral injection molding of the outer shell 10 can achieve the lightweight design of the motor controller 100.

[0035] In some embodiments, Figure 1 As shown, in the thickness direction of the capacitor structure 14 , the housing portion 142 is located on a side of the capacitor portion 141 facing the installation space 13 .

[0036] Thus, the shell portion 142 faces the installation space 13 so that the capacitor structure 14 can be protected by the housing 10 , so that the capacitor structure 14 is not easily damaged when the motor controller 100 is in use, thereby increasing the service life of the motor controller 100 .

[0037] In some embodiments, Figure 1-Figure 2 As shown, in the thickness direction of the capacitor structure 14 , housing portions 142 are disposed on both sides of the capacitor portion 141 .

[0038] Therefore, the shell part 142 is provided on both sides of the capacitor part 141 so that the capacitor part 141 can be protected by the shell part 142, making the capacitor part 141 less susceptible to the influence of the high-voltage device 16 in the installation space 13, so that the capacitor part 141 can better weaken and absorb the spike pulse.

[0039] In some embodiments, the capacitor 141 is configured as a thin film capacitor.

[0040] Therefore, the film capacitor has high insulation impedance, wide frequency response, and small dielectric loss, which makes the use effect of the motor controller 100 better.

[0041] In some embodiments, the film capacitor is configured as a metalized film, or the film capacitor is configured as a copper busbar.

[0042] Therefore, the metallized film can make the weight of the film capacitor lighter, thereby further realizing the lightweight design of the motor controller 100. When the film capacitor is constructed as a copper busbar, the film capacitor can better absorb pulses.

[0043] It should be noted that film capacitors are plastic-sealed by glue filling, which can better protect the film capacitors.

[0044] In some embodiments, the thin film capacitor is constructed as a sheet structure.

[0045] Therefore, the sheet structure makes it easier to place the thin film capacitor in the capacitor structure 14 . At the same time, the sheet structure can make the capacitor part 141 of the capacitor structure 14 thinner, so that the motor controller 100 as a whole can be made smaller, thereby realizing the miniaturized design of the motor controller 100 .

[0046] In some embodiments, the side wall 12 is configured as a capacitor structure 14 , and the capacitor portion 141 is disposed to surround the installation space 13 in a circumferential direction of the installation space 13 .

[0047] Therefore, the capacitor part 141 surrounds the installation space 13 and does not occupy the position of the installation space 13 for installing the high-voltage device 16 , thereby realizing a miniaturized design of the motor controller 100 .

[0048] In some embodiments, Figure 1 As shown, the wiring socket 15 is integrated with the housing 10 .

[0049] Therefore, the integration level inside the motor controller 100 is improved, and the high-voltage components in the installation space 13 are easier to be arranged, thereby realizing a miniaturized design of the motor controller 100 .

[0050] In some embodiments, Figure 1 As shown, the wiring seat 15 is located in the installation space 13 and is integrally injection molded with the housing 10 .

[0051] Therefore, the terminal holder 15 is integrally injection molded with the housing 10 , so that when the housing 10 is injection molded, the terminal holder 15 is also molded at the same time, which can avoid further processing at a later stage, thereby improving the assembly efficiency of the motor controller 100 .

[0052] It should be noted that the terminal block 15 in the related art is also made of plastic material, but the shell 10 is made of aluminum alloy die-casting. In this way, the terminal block 15 is not highly integrated when it is arranged in the installation space 13, which will affect the setting of the high-voltage device 16. The shell 10 and the terminal block 15 in the present application are integrally injection molded, so that the terminal block 15 can be directly integrated on the shell 10, thereby improving the integration of the motor controller 100 and realizing the miniaturization design of the motor controller 100.

[0053] The present invention also provides a vehicle 1000 .

At the same time, the integral injection molding of the outer shell 10 can achieve a lightweight design of the motor controller 100.
