請先參閱第1及2圖,本創作第1實施例之馬達托架總成10包含有一托架20與一驅動單元30。Referring to Figures 1 and 2, the motor bracket assembly 10 of the first embodiment of the present invention includes a bracket 20 and a drive unit 30.

托架20具有一承板21與一支撐管22。承板21之頂面由前往後分別與一前管12、一座管14,以及一後叉管16作連接,支撐管22在本實施例藉由三肋板23連接於承板21之底面。The bracket 20 has a carrier plate 21 and a support tube 22. The top surface of the carrier 21 is connected to a front tube 12, a tube 14, and a rear fork tube 16, respectively, and the support tube 22 is connected to the bottom surface of the carrier 21 by a three-ribbed plate 23 in this embodiment.

驅動單元30具有一外殼31,外殼31具有一第一側蓋32與一第二側蓋33,第一、第二側蓋32、33之間相互接合在一起且以鎖固或其他固定方式組裝於托架20之的兩相對側,使得驅動單元30會被托架20之 承板21所局部包覆住,此外,第一側蓋32之後端朝托架20的方向延伸出一曲柄軸管34,曲柄軸管34自支撐管22的一端穿設於支撐管22內,第二側蓋33之後端具有一軸孔35,軸孔35連通於支撐管22之另一端,藉此可讓一曲柄軸(圖中未示)經由軸孔35穿設於曲柄軸管34內。驅動單元30更具有一馬達36,馬達36安裝於外殼31之第一、第二側蓋32、33的前端之間,使得馬達36在安裝之後位於托架20之承板21的底面且被外殼31之第一、第二側蓋32、33所局部包覆住。藉此,馬達36即可提供助力給設於曲柄軸管34內之曲柄軸,以驅動曲柄軸轉動。The driving unit 30 has a casing 31 having a first side cover 32 and a second side cover 33. The first and second side covers 32, 33 are joined to each other and assembled by locking or other fixing. On opposite sides of the bracket 20, the drive unit 30 will be supported by the bracket 20 The carrier 21 is partially covered, and a crank tube 34 is extended from the rear end of the first side cover 32 toward the bracket 20, and the crank tube 34 is inserted into the support tube 22 from one end of the support tube 22, The rear end of the second side cover 33 has a shaft hole 35 which communicates with the other end of the support tube 22, whereby a crank shaft (not shown) is bored in the crank tube 34 via the shaft hole 35. The drive unit 30 further has a motor 36 mounted between the front ends of the first and second side covers 32, 33 of the housing 31 such that the motor 36 is located on the bottom surface of the carrier 21 of the bracket 20 after installation and is surrounded by the housing. The first and second side covers 32, 33 of the 31 are partially covered. Thereby, the motor 36 can provide assistance to the crankshaft provided in the crankshaft tube 34 to drive the crankshaft to rotate.

由上述結構可知,本創作之馬達托架總成10主要是在托架20之下方設置支撐管22讓外殼31之曲柄軸管34所穿設,再將馬達36設置於外殼31內,如此與習用專利案將馬達直接鎖固於托架的設計相比之下,本創作可以讓馬達36更穩定地與托架20固定在一起,藉以達到增加結構穩定性及減少應力集中的目的。It can be seen from the above structure that the motor bracket assembly 10 of the present invention is mainly provided with a support tube 22 disposed under the bracket 20 for the crank tube 34 of the outer casing 31 to be inserted, and then the motor 36 is disposed in the outer casing 31, so that In contrast to the design of the conventional patent that locks the motor directly to the bracket, the present invention allows the motor 36 to be more stably attached to the bracket 20 for the purpose of increasing structural stability and reducing stress concentration.

在此需要補充說明的是,本創作之結構可以有不同變化,如第3圖所示,托架40之支撐管42可以藉由一延伸管43連接於托架40之承板41的底面,延伸管43是由座管14之底端穿經承板41所形成,如此同樣可以達到將承板41與支撐管42固定在一起的效果。再如第4圖所示,托架50之承板51可以設計成環繞於驅動單元30之外周緣而將驅動單元30之外周緣整個包覆住,除了可以增加與驅動單元30之間在組裝完成後的結構穩定性,同時又能增加對驅動單元30的保護效果。It should be additionally noted that the structure of the present invention may be varied. As shown in FIG. 3, the support tube 42 of the bracket 40 may be coupled to the bottom surface of the carrier plate 41 of the bracket 40 by an extension tube 43. The extension tube 43 is formed by the bottom end of the seat tube 14 passing through the carrier plate 41, so that the effect of fixing the carrier plate 41 and the support tube 42 together can be achieved. As shown in FIG. 4, the carrier 51 of the bracket 50 can be designed to wrap around the outer periphery of the drive unit 30 to completely cover the outer periphery of the drive unit 30, except that it can be assembled with the drive unit 30. The structural stability after completion can simultaneously increase the protection effect on the driving unit 30.
