Abstract
Description
本發明係有關於一種電動割草機。The invention relates to an electric lawn mower.
按,近年來隨著環保意識的上升,割草機已普遍使用電動割草機取代燃油割草機,電動割草機具有低噪音、無排氣汙染及避免燃油外漏起火之優點,一般習知的電動割草機具有一桿體及設於桿體兩端之一座體及一控制部,該座體設有一轉子馬達,藉由轉子馬達之轉子帶動轉軸轉動時,轉軸即會帶動套設於轉軸之刀片組轉動,即可進行割草作業,於使用時係以一手握持於桿體位於座體及控制部之中間部位,另一手握持於控制部以控制馬達作動,TWM526804所揭露之電動割草機即屬此類。In recent years, with the rising awareness of environmental protection, lawn mowers have generally used electric lawn mowers to replace fuel lawn mowers. Electric lawn mowers have the advantages of low noise, no exhaust pollution and avoiding fuel leakage and fire. The known electric lawn mower has a rod body and a seat body provided at both ends of the rod body and a control part. The seat body is provided with a rotor motor. When the rotor of the rotor motor drives the rotating shaft to rotate, the rotating shaft will drive the sleeve. The blade set on the rotating shaft can be used for mowing. When in use, it is held in the middle of the seat body and the control part with one hand, and the motor is controlled by the other part with the other hand, as disclosed in TWM526804 The electric lawn mower belongs to this category.
然而,此類習知電動割草機於使用時,握持於控制部之手肘須大幅彎曲且手腕亦須彎曲,方可順利握持住控制部,當使用一段時間後即會導致肌肉及關節痠痛,需進行休息方可繼續工作,如此會導致工作效率下降,且長期使用下來會導致關節受傷等職業傷害,存在亟待改善之缺弊。However, when such a conventional electric lawn mower is used, the elbow held by the control part must be greatly bent and the wrist must also be bent to smoothly hold the control part. When used for a period of time, it will cause muscles and Joints are sore, and you need to take a break before you can continue to work. This will lead to a decrease in work efficiency, and long-term use will cause occupational injuries such as joint injuries. There are shortcomings that need to be improved.
因此,有必要提供一種新穎且具有進步性之電動割草機,以解決上述之問題。Therefore, it is necessary to provide a novel and progressive electric lawn mower to solve the above problems.
本發明之主要目的在於提供一種電動割草機,可令使用者在使用時以貼近人體工學之方式進行握持,以供進行長時間作業而不會導致肌肉及關節痠痛,以增加工作效率及避免造成關節受傷等職業傷害。The main purpose of the present invention is to provide an electric lawn mower which can be held by the user in an ergonomic way for long-term operation without causing muscle and joint pain, so as to increase work efficiency And avoid occupational injuries such as joint injuries.
為達成上述目的,本發明提供一種電動割草機,其包括一直桿段、一握把段及一座頭。該握把段設於該直桿段之一端,該握把段設有一控制把手,該握把段之長度方向與該直桿段之長度方向之間具有一第一夾角,該第一夾角介於25度至65度之間。該座頭設於該直桿段相對該握把段之一端,包括一轉動馬達,該轉動馬達具有一轉軸,該轉軸之一轉動徑向與該直桿段之長度方向之間具有一第二夾角,該第二夾角介於25度至65度之間。To achieve the above object, the present invention provides an electric lawn mower, which includes a straight rod section, a grip section and a head. The grip section is provided at one end of the straight rod section, the grip section is provided with a control handle, and there is a first included angle between the length direction of the grip section and the longitudinal direction of the straight rod section, the first included angle is between Between 25 degrees and 65 degrees. The seat is disposed at one end of the straight rod section opposite to the grip section, and includes a rotating motor with a rotating shaft, and a second included angle between a rotating radial direction of the rotating shaft and the length direction of the straight rod section The second included angle is between 25 degrees and 65 degrees.
以下僅以實施例說明本發明可能之實施態樣,然並非用以限制本發明所欲保護之範疇,合先敘明。The following merely illustrates the possible implementation forms of the present invention with examples, but it is not intended to limit the scope of the invention to be protected, and will be described first.
請參考圖1至3,其顯示本發明之一較佳實施例,本發明之電動割草機包括一直桿段1、一握把段2及一座頭3。Please refer to FIGS. 1 to 3, which show a preferred embodiment of the present invention. The electric lawn mower of the present invention includes a
該握把段2設於該直桿段1之一端,該握把段2設有一控制把手21,該握把段2之長度方向與該直桿段1之長度方向之間具有一第一夾角Θ1,該第一夾角Θ1介於25度至65度之間。The
該座頭3設於該直桿段1相對該握把段2之一端,包括一轉動馬達31,該轉動馬達31具有一轉軸32,該轉軸32之一轉動徑向33與該直桿段1之長度方向之間具有一第二夾角Θ2,該第二夾角Θ2介於25度至65度之間。The
較佳地,該第一夾角Θ1與該第二夾角Θ2介於30度至45度之間,該第一夾角Θ1與該第二夾角Θ2之角度相同,該握把段2相對該直桿段1朝遠離該座頭3之方向彎折,該座頭3相對該直桿段1朝遠離該握把段2之方向彎折,於本實施例中該第一夾角Θ1與該第二夾角Θ2為35度,如此使用者握持於該握把段2之手肘及手腕可呈伸直狀態握持於該控制把手21而無須彎曲,使用者之手臂肌肉較無須出力,因此可長時間作業而不會導致使用者手臂之肌肉及關節痠痛,以增加工作效率。Preferably, the first included angle Θ1 and the second included angle Θ2 are between 30 degrees and 45 degrees, the first included angle Θ1 and the second included angle Θ2 have the same angle, and the
