本創作有關一種電動汽車，尤指一種電動汽車電驅動系統的總成結構。This creation relates to an electric vehicle, and more particularly to an assembly structure of an electric vehicle electric drive system.

目前車用電機驅動系統的總成設計，主要有以下兩個方向的總成：一種是採用了電機與電機控制器的物理總成，這種總成使電機與電機控制器之間的三相線束從外部走線，集中到系統內部的銅極板，可以有效的降低系統成本；另一種是將電機，電機控制器與變速箱組合到一起，可以提高系統一體化，但是其相當於將電機、變速箱、電機控制器進行物理組合，並沒有進行有效的結構變形與設計，在系統體積功率密度上面不具優勢。At present, the assembly design of the motor drive system for the vehicle mainly has the following two directions: one is a physical assembly using a motor and a motor controller, and the assembly makes a three-phase between the motor and the motor controller. The wiring harness is routed from the outside to the copper plate inside the system, which can effectively reduce the system cost. The other is to combine the motor, the motor controller and the gearbox to improve the system integration, but it is equivalent to the motor. The physical combination of the gearbox and the motor controller does not carry out effective structural deformation and design, and has no advantage in system volume power density.

本創作在結構的佈置上，利用電機與變速箱固有連接結構之間的畸零空間，重新設計電機控制器的結構，使其為異型結構，以充分利用變速箱輸出半軸上方的空間，從而實現電驅動系統的總體體積最佳化的目的。In the arrangement of the structure, the structure of the motor controller is redesigned by using the distorted space between the motor and the inherent connection structure of the gearbox, so that it is shaped to fully utilize the space above the output shaft of the gearbox. The overall volume of the electric drive system is optimized for the purpose.

The assembly structure 1 of the motor drive system of an electric vehicle includes three main components of the motor 10, the gearbox 20, and the motor controller 30. In FIG. 2, the outer casing of the motor 10 has a front end cover 11, a motor housing 12, and a rear end cover 13, and the front end cover 11 and the rear end cover 13 are located opposite to each other on both sides of the motor housing 12, and the motor housing 12 is connected between the front end cover 11 and the rear end cover 13, and the front end cover 11 is of a profile design. The motor 10 additionally has a bracket 14 that extends forward of the motor housing 12. The gearbox 20 has an input shaft 24 and an output half shaft 22, the input shaft 24 is coupled to the rear end cover 13 side of the motor 10, and the output half shaft 22 extends in front of the motor housing 12 of the motor 10 and is supported by the bracket 14. Cover and fix the suspension. When the motor 10 is coupled to the gearbox 20, a zero-distortion space 40 is formed between the motor 10 and the inherent connection structure of the gearbox 20, specifically by the front end cover 11, the motor housing 12, and the rear end cover 13 and the gearbox 20. Together they form.

電機控制器30的箱體最佳化設計為異型輪廓，以充分利用變速箱20的輸出半軸22上部空間，同時縮小電驅動系統在整體上的佔用空間。電機控制器30安裝於前述的畸零空間40且固設於電機10的電機殼體12上，且電機控制器30的前端同時固定懸置於前端蓋11的支架14上，以實現電機控制器30的穩定固定。The cabinet of the motor controller 30 is optimally designed as a profiled profile to take full advantage of the upper space of the output half shaft 22 of the gearbox 20 while reducing the overall footprint of the electric drive system. The motor controller 30 is mounted on the aforementioned zero-distortion space 40 and is fixed on the motor housing 12 of the motor 10, and the front end of the motor controller 30 is simultaneously fixedly suspended on the bracket 14 of the front end cover 11 to realize the motor controller. 30 is stable and fixed.

請參考圖4，圖4是總成結構中具有異型輪廓的電機控制器的側視圖。異型輪廓的電機控制器30的外部結構包含有頂蓋31、底蓋33以及殼體34。由側面來看，殼體34具有第一面341、第二面342以及第三面343，其中如圖所示，第二面342以及第三面343位在同一側（或底側），而第一面341則與第二面342以及第三面343位於相對的另一側（或頂側）。位於同一側的第二面342以及第三面343之間具有段差（也就是第二面342與第三面343未在同一平面上），目的是為了使電機控制器30能夠充分運用到電機10以及變速箱20之間的畸零空間40，也就是說電機控制器30在第三面343與第一面341之間的部位主要位於電機10的電機殼體12上，因此厚度較薄。而電機控制器30在第二面342與第一面341之間的部位主要位於支架14上，因此可以設計較厚的空間。Please refer to FIG. 4. FIG. 4 is a side view of the motor controller having a profiled profile in the assembly structure. The outer structure of the profiled motor controller 30 includes a top cover 31, a bottom cover 33, and a housing 34. Viewed from the side, the housing 34 has a first face 341, a second face 342, and a third face 343, wherein as shown, the second face 342 and the third face 343 are on the same side (or bottom side), The first surface 341 is located on the opposite side (or top side) from the second surface 342 and the third surface 343. The second surface 342 and the third surface 343 on the same side have a step (that is, the second surface 342 and the third surface 343 are not in the same plane) for the purpose of fully utilizing the motor controller 30 to the motor 10. And the distortion space 40 between the gearboxes 20, that is, the portion of the motor controller 30 between the third face 343 and the first face 341 is mainly located on the motor housing 12 of the motor 10, and thus the thickness is thin. The portion of the motor controller 30 between the second face 342 and the first face 341 is mainly located on the bracket 14, so that a thicker space can be designed.

頂蓋31結合於殼體34的第一面341上，而底蓋33結合於殼體34的第二面342上。此外，電機控制器30透過三相銅排32（銅極板）與電機直接連接，減少三相線束的使用，降低發熱。在外觀上，三相銅排32延伸於殼體34的第三面343外，在電機控制器30的第三面343固設於電機殼體12時，三相銅排32即與電機直接連接。另外，在電機控制器30設置於畸零空間40時，電機控制器30的底蓋33固定懸置於支架14上，而在電機10與電機控制器30之間採用了O型圈進行徑向密封，在電機控制器30的塑料接線座與電機10的支架14之間也採用O型圈進行徑向密封，實現電驅動系統內部的防護需求，防止電機10內部的水汽進入到電機控制器30內部。The top cover 31 is coupled to the first side 341 of the housing 34 and the bottom cover 33 is coupled to the second side 342 of the housing 34. In addition, the motor controller 30 is directly connected to the motor through a three-phase copper busbar 32 (copper plate) to reduce the use of the three-phase wire harness and reduce heat generation. In appearance, the three-phase copper row 32 extends outside the third surface 343 of the housing 34. When the third surface 343 of the motor controller 30 is fixed to the motor housing 12, the three-phase copper row 32 is directly connected to the motor. connection. In addition, when the motor controller 30 is disposed in the distortion space 40, the bottom cover 33 of the motor controller 30 is fixedly suspended on the bracket 14, and an O-ring is used for radial sealing between the motor 10 and the motor controller 30. An O-ring is also used for radial sealing between the plastic terminal block of the motor controller 30 and the bracket 14 of the motor 10 to realize the protection requirement inside the electric drive system to prevent moisture inside the motor 10 from entering the motor controller 30. .

當電機10與電機控制器30通過懸置固定的方式連接時，在電機控制器30與電機10的外殼之間可另外設置導熱墊，以將電機控制器30的三相極板產生的熱能，通過電機10的外殼水道進行散熱，也能夠確保電驅動系統的散熱需求。When the motor 10 and the motor controller 30 are connected in a suspended manner, a thermal pad may be additionally disposed between the motor controller 30 and the outer casing of the motor 10 to generate thermal energy from the three-phase plates of the motor controller 30, The heat dissipation by the outer water channel of the motor 10 also ensures the heat dissipation requirements of the electric drive system.
