[0046] Figure 1 This is a perspective view of a control device according to an embodiment of the present invention, showing the axes X, Y, and Z. Figure 2 yes Figure 1 A perspective view of some components of the control device. Please refer to... Figure 1 and Figure 2 In this embodiment, the control device 10 is, for example, a power control unit (PCU) of a vehicle engine. The control device 10 includes a control unit 100, which includes a housing 110, a cover 120, a first electrical component 130, and a second electrical component 140. The cover 120 has a polygonal shape and covers the housing 110. The first electrical component 130 is, for example, an inverter, and the second electrical component 140 is, for example, a reactor. The first electrical component 130 and the second electrical component 140 are disposed within the housing 110.

[0047] Figure 3 yes Figure 1 A three-dimensional diagram of the cover. Figure 4 yes Figure 1 The bottom view of the cover. Please refer to... Figure 3 and Figure 4 In this embodiment, the cover 120 has a top wall 122, a side wall 124, and a plurality of fixing parts 126. The side wall 124 extends from the top wall 122 toward the housing 110 (shown in...). Figure 1 These fixing portions 126 are formed on the sidewall 124 and are used to secure the housing 110 (shown in) by locking or other suitable means. Figure 1 Multiple fixing portions 112 of the top wall 122 are provided for the housing 110 (shown in the figure). Figure 1 The first rib 1221 protrudes, and the first rib 1221 is at least partially located in the central part C of the cover body 120 (indicated in...). Figure 4 The first rib 1221 includes a plurality of branches 1221a, which extend toward the fixing portions 126 and connect to the sidewalls 124 adjacent to the fixing portions 126. Specifically, the first rib 1221 is at least partially located at the center of the cover 120 in the front-rear direction (axial Y) and the left-right direction (axial X), and the first rib 1221 is located at the center of the housing 110 in the longitudinal direction (axial Y) of the control device 10 relative to the second electrical member 140.

[0048] As described above, in the control device 10 of this embodiment, the top wall 122 of the cover 120 has a first rib 1221 protruding into the housing 110. The first rib 1221 is formed at the central portion C of the cover 120 and is located at the main resonance point of the cover 120, which can concentrate and strengthen the part of the cover 120 that is prone to vibration. Furthermore, the first rib 1221 is connected to the side wall 124 at the fixing portion 126, which can improve the rigidity of the cover 120 and thereby reduce the vibration amplitude of the cover 120. Thus, the vibration of the cover 120 of the control device 10 of this embodiment can be suppressed to reduce vibration noise.

[0049] Figure 5 yes Figure 1 The top view of the control device. Please refer to... Figure 2 and Figure 5 In this embodiment, the first electrical component 130 and the second electrical component 140 are arranged side by side in the longitudinal direction (axial Y) of the control device 10. The upper surface 140a of the second electrical component 140 is positioned higher than the upper surface 130a of the first electrical component 130, and the first rib 1221 is offset from the second electrical component 140 in the vertical direction (axial Z) of the control device 10. Accordingly, the first rib 1221 and the taller second electrical component 140 will not interfere with each other, and the internal configuration space of the control unit 100 can be utilized efficiently to reduce the height of the control device 10 in the vertical direction (axial Z), and the first rib 1221 has sufficient height to effectively increase the rigidity of the cover 120.

[0050] Please refer to Figures 3 to 5 In this embodiment, the top wall 122 of the cover 120 also has a second rib 1222. The second rib 1222 is located at a position overlapping the second electrical member 140 in the vertical direction (axial Z) of the control device 10, and the second rib 1222 has a notch 1222a at the position. Accordingly, the rigidity of the cover 120 can be further improved by the second rib 1222, and the insulating distance between the second rib 1222 and the second electrical member 140 can be ensured by the notch 1222a. In addition, the top wall 122 of the cover 120 also has a third rib 1223. The third rib 1223 connects the first rib 1221 and the second rib 1222 to further improve the rigidity of the cover 120.

[0051] Figure 6 yes Figure 1 A sectional view of the control device along line II. Please refer to... Figure 6In this embodiment, the lower surface S1 of the first rib 1221 extends to the lower surface S2 of the side wall 124 of the cover 120. This increases the connection length between the side wall 124 and the first rib 1221 in the vertical direction (axial direction Z), thereby improving the rigidity of the first rib 1221. Furthermore, in this embodiment, the second electrical member 140 is closer to the top wall 122 of the cover 120 than the first electrical member 140. Correspondingly, the top 1241 of the side wall 124 of the cover 120 slopes towards the top wall 122 along the direction D from the first electrical member 130 to the second electrical member 140. That is, the height of the side wall 124 of the cover 120 gradually increases along the direction D, causing the top wall 122 to slope upwards along the direction D. As described above, the height of the top wall 122 of the cover 120 is set in accordance with the height of the first electrical component 140 and the height of the second electrical component 140, so that the height of the cover 120 can be reduced as much as possible while forming the first rib 1221, the second rib 1222 and the third rib 1223 below the top wall 122.

[0052] Figure 7 yes Figure 1 A side view of the cover. Please refer to... Figure 7 In this embodiment, the sidewall 124 has at least one side rib (shown as a plurality of first side ribs 124a and a plurality of second side ribs 124b), each first side rib 124a and each second side rib 124b being located between two fixing portions 126 and extending toward the housing 110 (shown in Figure 1 The outer side protrudes to enhance the rigidity of the cover 120 and its first rib 1221, second rib 1222, and third rib 1223. Furthermore, due to the sidewall 124 of the cover 120 as... Figure 6 The first side rib 124a and the second side rib 124b are correspondingly longer in the vertical direction (axial Z) and have good rigidity because the second electrical component 140 has a greater height.

[0053] Furthermore, each second side rib 124b is adjacent to the fixing part 126, and each first side rib 124a is located between the two second side ribs 124b. Figure 7 The shapes and sizes of the second side rib 124b and the first side rib 124a are for illustrative purposes only. In practice, the thickness of each second side rib 124b can be greater than the thickness of each first side rib 124a. Accordingly, by making the second side rib 124b next to the fixing part 126 have a larger thickness, the rigidity at the fixing part 126 is improved, thereby improving the rigidity of the first rib 1221, the second rib 1222, and the third rib 1223.

[0054] In summary, in the control device of this invention, the top wall of the cover has a first rib protruding into the shell. The first rib is formed in the central part of the cover and is located at the main resonance point of the cover. It can concentrate and strengthen the parts of the cover that are prone to vibration. Furthermore, the first rib is connected to the side wall at the fixing part, which can improve the rigidity of the cover and thus reduce the vibration amplitude of the cover. Therefore, the vibration of the cover of the control device of this invention can be suppressed to reduce vibration noise.
