Description
本發明涉及一種馬達之框架，尤其是一種藉由一塑膠軸管一體包覆一金屬底板所構成的馬達底座結構。The invention relates to a frame of a motor, in particular to a motor base structure formed by integrally covering a metal bottom plate with a plastic shaft tube.
目前常見之習知馬達框架，大致包含一底座及一框體，且該習知馬達框架可供結合如定子及轉子等構件，以組成一馬達結構。一般而言，前述習知馬達底座及框體可以塑膠材料一體射出成型，惟當該馬達框架之整體結構皆以塑膠材料製成時，則具有結構強度不佳等問題。The conventional conventional motor frame generally includes a base and a frame, and the conventional motor frame can be combined with components such as a stator and a rotor to form a motor structure. In general, the conventional motor base and the frame body can be integrally molded by plastic material. However, when the overall structure of the motor frame is made of a plastic material, there is a problem that the structural strength is not good.
又，為改善前述以塑膠材料製成之馬達框架所衍生的問題，市面上亦具有一種習知馬達框架之整體結構皆以金屬材料一體壓鑄成型，以便增加結構強度及提升散熱效果；或者，亦有習知馬達框架係藉由價格較低的塑膠材料製成該框體，再以金屬材料製成該底座，以便維持一定之結構強度及兼具有較佳之散熱效果等優點。因此，如以提升習知馬達框架之結構強度及散熱效果作為前提條件，則較佳仍以選用金屬材質製成之底座為優先考量。Moreover, in order to improve the problems arising from the aforementioned motor frame made of plastic material, there is also a conventional motor frame on the market which is integrally die-casted with a metal material to increase structural strength and improve heat dissipation; or Conventional motor frames are made of a lower-priced plastic material, and the base is made of a metal material to maintain a certain structural strength and a better heat dissipation effect. Therefore, if the structural strength and heat dissipation effect of the conventional motor frame are taken as a precondition, it is preferable to use a base made of a metal material as a priority.
請參照第1圖所示，如中華民國第M337062號「散熱風扇之絕緣基座結構」專利案，係揭示一種以金屬材質製成的馬達底座，該底座為一絕緣基座9，該絕緣基座9包含有一金屬座板91及一塑膠支柱92。該金屬座板91設有一穿孔911及數個斜爪片912，該數個斜爪片912之一端連接於該穿孔911之周緣，另一端向該穿孔911中心傾斜 延伸；該塑膠支柱92之一端設有一肩部921，且該塑膠支柱92在該肩部921處呈外徑較大之形態。藉此，如第2圖所示，該塑膠支柱92之肩部921可以射出成型方式一體包覆該數個斜爪片912，以構成該絕緣基座9，並藉由該數個斜爪片912，防止該塑膠支柱92任意轉動及脫落。Please refer to FIG. 1 , for example, the patent of "Insulation Base Structure of Radiating Fan" of the Republic of China No. M337062, discloses a motor base made of a metal material, the base is an insulating base 9, the insulating base The seat 9 includes a metal seat plate 91 and a plastic post 92. The metal seat plate 91 is provided with a through hole 911 and a plurality of diagonal claw pieces 912. One end of the plurality of diagonal claw pieces 912 is connected to the periphery of the through hole 911, and the other end is inclined toward the center of the through hole 911. Extending; one end of the plastic post 92 is provided with a shoulder 921, and the plastic post 92 has a larger outer diameter at the shoulder 921. Therefore, as shown in FIG. 2, the shoulder portion 921 of the plastic post 92 can integrally cover the plurality of diagonal claw pieces 912 by injection molding to form the insulating base 9 and the plurality of oblique claw pieces 912, the plastic post 92 is prevented from rotating and falling off arbitrarily.
上述習知絕緣基座9在實際使用時，由於該數個斜爪片912皆為傾斜形態，使得該塑膠支柱92需額外設置管壁厚度較大之該肩部921，以由該肩部921一體包覆該數個斜爪片912；再且，為求該肩部921與該數個斜爪片912之間可穩固結合，如第2圖所示，該塑膠支柱92之肩部921的軸向高度(B1 )必須大於各該斜爪片912的軸向高度(B2 )，方可將各該斜爪片912完全包覆於該肩部921中，故導致該塑膠支柱92必須使用較多的塑膠材料，造成整體製造成本提高，同時，也使該習知絕緣基座9之徑向寬度及軸向高度較大，不利於馬達輕薄短小之發展目標。In the actual use of the above-mentioned insulating base 9 , since the plurality of diagonal claw pieces 912 are in an inclined shape, the plastic post 92 needs to additionally provide the shoulder portion 921 having a large wall thickness, so that the shoulder portion 921 is provided. The plurality of diagonal claw pieces 912 are integrally covered; further, in order to securely couple the shoulder portion 921 and the plurality of diagonal claw pieces 912, as shown in FIG. 2, the shoulder portion 921 of the plastic pillar 92 is The axial height (B 1 ) must be greater than the axial height (B 2 ) of each of the diagonal claw pieces 912, so that each of the diagonal claw pieces 912 can be completely covered in the shoulder portion 921, so that the plastic post 92 must be The use of more plastic materials leads to an increase in the overall manufacturing cost, and at the same time, the radial width and axial height of the conventional insulating base 9 are large, which is not conducive to the development goal of the motor being light and thin.
綜上所述，習知絕緣基座9雖可藉由該金屬座板91提供較佳之結構強度及散熱效果，惟仍有加以改善之必要。In summary, the conventional insulating base 9 can provide better structural strength and heat dissipation effect by the metal seat plate 91, but it is still necessary to be improved.

Rotation occurs relative to the metal base plate 10.
請參照第12及13圖所示，係揭示本發明之第五實施例，本實施例大致上同於第一實施例，其主要差異在於該固接件12之定位結構123形態，因此針對本實施例與第一實施例結構相同之部分則不再贅述。Referring to Figures 12 and 13, the fifth embodiment of the present invention is disclosed. The present embodiment is substantially the same as the first embodiment. The main difference lies in the shape of the positioning structure 123 of the fixing member 12, and therefore The same components as those of the first embodiment will not be described again.
在本實施例中，該固接件12較佳可選擇為數個間隔設置之爪片12a，該數個爪片12a可呈環狀排列之形態，但不以此為限。此外，各該爪片12a可呈旋曲狀，使該固接件12之外周面121及內周面122形成旋扭之弧面，以形成該固接件12之定位結構123。In this embodiment, the fixing member 12 is preferably a plurality of spaced apart claw pieces 12a, and the plurality of claw pieces 12a may be arranged in a ring shape, but not limited thereto. In addition, each of the claw pieces 12a can be formed in a curved shape, so that the outer peripheral surface 121 and the inner peripheral surface 122 of the fixing member 12 form a curved arc surface to form the positioning structure 123 of the fixing member 12.
藉由前述結構，於實際組裝時，可將該金屬底板10預先置入一射出成型模具之一模穴內的預定位置，該模穴係用以射出成型該塑膠軸管20；在該模穴注入塑料以一體射出成型該塑膠軸管20的過程中，使塑料完整包覆該固接件12之外周面121及內周面122，並於凝固後形成該塑膠軸管20之射包區段21，藉由呈旋曲弧狀之該外周面121及內周面122提供不同方向的拉持分力，使該塑膠軸管20可穩固定位結合於該金屬底板10，無法從該金屬底板10上脫出，亦無法相對該金屬底板10產生轉動。With the foregoing structure, in actual assembly, the metal base plate 10 can be preliminarily placed in a predetermined position in a cavity of one of the injection molding molds for projecting and molding the plastic shaft tube 20; Injecting the plastic to integrally form the plastic shaft tube 20, the plastic completely covers the outer peripheral surface 121 and the inner peripheral surface 122 of the fixing member 12, and forms a packet portion of the plastic shaft tube 20 after solidification. 21, the outer peripheral surface 121 and the inner peripheral surface 122 of the arcuate arc shape provide a pulling force component in different directions, so that the plastic shaft tube 20 can be stably fixedly coupled to the metal base plate 10, and cannot be removed from the metal base plate 10.
