請參照第1、6圖，其係本發明吊扇馬達的第一實施例，該吊扇馬達大致上包含一套管1、一定子2、一轉子3、一芯軸4及一防鬆套組5，該定子2及該轉子3分別設於該套管1，該芯軸4貫穿該套管1，該防鬆套組5結合該套管1及該芯軸4。 Please refer to FIGS. 1 and 6, which are the first embodiment of the ceiling fan motor according to the present invention. The ceiling fan motor generally includes a set of tubes 1, a stator 2, a rotor 3, a mandrel 4, and an anti-loosening set 5. The stator 2 and the rotor 3 are respectively disposed on the sleeve 1, the core shaft 4 passes through the sleeve 1, and the anti-loosening sleeve group 5 is combined with the sleeve 1 and the core shaft 4.
該套管1設有一定子結合部11及一轉子結合部12，以分別供該定子2及該轉子3組裝定位；該套管1另設有一限位部13，以供該防鬆套組5卡固結合。在本實施例中，該限位部13可以為貫穿該套管1內、外周面的一側剖溝13a，以供該防鬆套組5的局部卡固結合；較佳地，該側剖溝13a可以延伸至該套管1的頂、底端面，並於該側剖溝13a中設置一隔線件14，使該側剖溝13a可兼作供拉牽該定子2接線的部位，同時可由該隔線件14防止該定子2接線穿入該套管1內部，避免該芯軸4貫穿該套管1時造成該定子2接線的損傷。 The sleeve 1 is provided with a stator coupling portion 11 and a rotor coupling portion 12 for the stator 2 and the rotor 3 to be assembled and positioned respectively; the sleeve 1 is further provided with a limiting portion 13 for the anti-loosening sleeve set 5 snap-in combination. In this embodiment, the limiting portion 13 may be a groove 13a cut through one side of the inner and outer peripheral surfaces of the sleeve 1 for local locking and combination of the anti-loosening sleeve group 5; preferably, the side cut The groove 13a can extend to the top and bottom end faces of the sleeve 1, and a wire spacer 14 is provided in the side section groove 13a, so that the side section groove 13a can also serve as a place for pulling the connection of the stator 2, and can be used at the same time. The wire separation member 14 prevents the connection of the stator 2 from penetrating into the inside of the sleeve 1, and prevents damage to the connection of the stator 2 when the mandrel 4 penetrates the sleeve 1.
該定子2定位於該套管1外周的定子結合部11，該定子2具有一鐵芯21；該轉子3則可例如由二滾珠軸承31可旋轉地設於該套管1外周的轉子結合部12，該轉子3另具有一磁性件32與該定子2的鐵芯21相對以便感磁，從而可由該定子2驅動該轉子3旋轉。 The stator 2 is located at a stator joint 11 on the outer periphery of the sleeve 1, and the stator 2 has an iron core 21; the rotor 3 may be rotatably provided on the rotor joint on the outer periphery of the sleeve 1, for example, by two ball bearings 31 12. The rotor 3 further has a magnetic member 32 opposite to the iron core 21 of the stator 2 so as to be magnetically sensitive, so that the rotor 2 can be driven by the stator 2 to rotate.
該芯軸4具有一裸露段4a及一穿伸段4b，該芯軸4在該裸露段4a與該穿伸段4b相連接處形成一肩部41；該穿伸段4b貫穿該套管1，以由該肩部41抵接該套管1的頂端，且該芯軸4具有一螺合部42穿出該套管1的底端，以供結合該防鬆套組5。 The mandrel 4 has a bare section 4a and a penetrating section 4b. The mandrel 4 forms a shoulder 41 at the junction of the bare section 4a and the penetrating section 4b; the penetrating section 4b runs through the sleeve 1 The abutment 41 abuts the top end of the sleeve 1, and the mandrel 4 has a screwing portion 42 penetrating the bottom end of the sleeve 1 for coupling with the anti-loosening sleeve group 5.
請參照第2圖，該防鬆套組5具有一卡固件51、一螺固件52、一防轉件53及一螺絲54。該卡固件51可設有一凸起部511及至少一 螺孔512，該螺固件52的外周面呈非圓形，該防轉件53則設有一防轉孔531及一長弧槽532，該防轉孔531的截面形狀呈非圓形且較佳與該螺固件52的外周面形狀相符；該螺絲54可貫穿該防轉件53的長弧槽532並螺合該卡固件51的螺孔512，以結合該防轉件53與該卡固件51。 Referring to FIG. 2, the anti-loosening set 5 includes a card fastener 51, a screw fastener 52, an anti-rotation member 53, and a screw 54. The fixing member 51 may be provided with a protruding portion 511 and at least one A screw hole 512. The outer peripheral surface of the screw member 52 is non-circular. The anti-rotation member 53 is provided with an anti-rotation hole 531 and a long arc groove 532. The cross-sectional shape of the anti-rotation hole 531 is non-circular and is preferably The screw 54 can pass through the long arc slot 532 of the anti-rotation member 53 and screw the screw hole 512 of the fixing member 51 to combine the anti-rotation member 53 and the fixing member 51. .
請參照第3、4、6圖，據由前述結構，將該芯軸4組裝至該套管1，使該芯軸4的螺合部42穿出該套管1底端後，可將該防鬆套組5的卡固件51套設在該螺合部42外周並抵接該套管1的底端面；同時，使該卡固件51的凸起部511伸入該套管1的側剖溝13a以卡固該套管1，令該卡固件51幾乎無法相對於該套管1旋轉。續將該螺固件52螺合該芯軸4的螺合部42並直接或間接地壓抵該卡固件51。 Referring to Figures 3, 4, and 6, according to the foregoing structure, the mandrel 4 is assembled to the sleeve 1, and after the screwing portion 42 of the mandrel 4 penetrates the bottom end of the sleeve 1, the The locking member 51 of the anti-loosening sleeve group 5 is sleeved on the outer periphery of the screwing portion 42 and abuts the bottom end surface of the sleeve 1; at the same time, the protruding portion 511 of the locking member 51 is extended into the side section of the sleeve 1 The groove 13 a fixes the sleeve 1, so that the fastener 51 can hardly rotate relative to the sleeve 1. Continue to screw the screw member 52 to the screwing portion 42 of the mandrel 4 and directly or indirectly press against the card member 51.
請參照第4、5、6圖，接著，將該防轉件53由該防轉孔531套於該螺固件52的外周，使該卡固件51的螺孔512能對位於該防轉件53的長弧槽532中，以由該螺絲54貫穿該長弧槽532並螺合該螺孔512，將該防轉件53與該卡固件51結合。 Please refer to FIGS. 4, 5 and 6. Next, the anti-rotation member 53 is sleeved by the anti-rotation hole 531 on the outer periphery of the screw member 52, so that the screw hole 512 of the card member 51 can be located on the anti-rotation member 53. In the long arc slot 532, the screw 54 penetrates the long arc slot 532 and is screwed with the screw hole 512, so that the anti-rotation member 53 is combined with the fixing member 51.
據此，由於該卡固件51卡固於該套管1，且該防轉件53結合該卡固件51，故該防轉件53同樣不易相對於該套管1旋轉；而該防轉件53又可由該防轉孔531限制該螺固件52無法旋轉，因此該螺固件52螺合該芯軸4的螺合部42後，即使該吊扇馬達運作時產生震動，該螺固件52仍不易相對於該芯軸4的螺合部42轉動，從而可以達到防止該螺固件52鬆動的效果。是以，本發明的吊扇馬達不易因該螺固件52鬆動而產生運作異音，該吊扇馬達的各構件也可維持穩固結合，除可延長各構件的使用壽命外，更可避免發生吊扇馬達的局部構件脫落等意外，以提升該吊扇馬達的使用安全性。 According to this, since the card holder 51 is fixed to the sleeve 1 and the anti-rotation member 53 is combined with the card holder 51, the anti-rotation member 53 is also difficult to rotate relative to the sleeve 1; and the anti-rotation member 53 The anti-rotation hole 531 can restrict the screwing member 52 from rotating. Therefore, after the screwing member 52 is screwed to the screwing portion 42 of the mandrel 4, even if the ceiling fan motor generates vibration, the screwing member 52 is still not easy to be relative to The screwing portion 42 of the mandrel 4 rotates, so that the effect of preventing the screwing member 52 from loosening can be achieved. Therefore, the ceiling fan motor of the present invention is not prone to generate abnormal sounds due to the loosening of the screw member 52. The components of the ceiling fan motor can also maintain a stable combination. In addition to extending the service life of each component, the ceiling fan motor can be avoided. Accidents such as the loss of local components to improve the safety of the ceiling fan motor.
此外，請再參照第1、6圖，本發明的吊扇馬達還可在該套管1的頂端設有一第一凹槽15，及在該芯軸4的裸露段4a設有連通至該 肩部41的一第二凹槽43；該吊扇馬達另具有一強化塊6結合該芯軸4，且該強化塊6位於該第一凹槽15及該第二凹槽43中。例如但不限制地，該芯軸4可設有一第一結合孔44位於該第二凹槽43中，該強化塊6則設有一第二結合孔61，該第二結合孔61與該第一結合孔44相對並由一結合件7貫穿結合。 In addition, please refer to FIGS. 1 and 6 again. The ceiling fan motor of the present invention may further be provided with a first groove 15 at the top end of the sleeve 1, and the exposed section 4 a of the mandrel 4 may be connected to the first groove 15 a. A second groove 43 of the shoulder 41; the ceiling fan motor further has a reinforcing block 6 combined with the mandrel 4, and the reinforcing block 6 is located in the first groove 15 and the second groove 43. For example, without limitation, the mandrel 4 may be provided with a first coupling hole 44 located in the second groove 43, and the reinforcing block 6 is provided with a second coupling hole 61. The second coupling hole 61 and the first coupling hole 61 The coupling holes 44 are opposed and penetrated by a coupling member 7.
據此，本發明的吊扇馬達可以由該強化塊6大幅增加該套管1與該芯軸4結合處的抗扭轉效果。如此一來，即使該轉子3的滾珠軸承31到達其使用壽命而產生卡死等狀況，以致該滾珠軸承31的內環突然隨外環旋轉，造成該套管1相對於該芯軸4轉動，也能由該強化塊6分散受力，避免該剪切力破壞該套管1與該芯軸4的結合關係而導致吊扇馬達的局部構件脫落，故該強化塊6可與前述的防鬆套組5相輔相成，更進一步地提升該吊扇馬達的使用安全性。 According to this, the ceiling fan motor of the present invention can greatly increase the anti-rotation effect of the joint of the sleeve 1 and the mandrel 4 by the reinforcing block 6. In this way, even if the ball bearing 31 of the rotor 3 reaches the end of its service life, and other situations such as jamming, the inner ring of the ball bearing 31 suddenly rotates with the outer ring, causing the sleeve 1 to rotate relative to the core shaft 4, The reinforcing block 6 can also be used to disperse the force to prevent the shearing force from destroying the coupling relationship between the sleeve 1 and the mandrel 4 and causing local components of the ceiling fan motor to fall off. Therefore, the reinforcing block 6 can be combined with the aforementioned anti-loosening sleeve. Group 5 complement each other to further enhance the safety of the ceiling fan motor.
請參照第7圖，本發明吊扇馬達的第二實施例的套管1與防鬆套組5係以不同於第一實施例的結構相互卡固結合，其餘構件大致上同於上述的第一實施例，故以下不再詳述。 Referring to FIG. 7, the sleeve 1 and the anti-loosening sleeve group 5 of the second embodiment of the ceiling fan motor of the present invention are engaged with each other with a structure different from that of the first embodiment, and the remaining components are substantially the same as the first Example, so it will not be described in detail below.
在本發明的第二實施例中，該套管1的限位部13可以為設於該套管1底端面的至少一切角13b，使該套管1的底端面形成非圓形。該防鬆套組5的卡固件51則可設有一卡管孔513，該卡管孔513的截面形狀呈非圓形且較佳與該套管1的底端面形狀相符。據此，該卡固件51可以由該卡管孔513套合該套管1底端的外周面，並使該卡固件51幾乎無法相對於該套管1旋轉，以穩固供該防轉件53結合，同樣可達到由該防轉件53限制該螺固件52無法相對於該芯軸4旋轉的效果。 In the second embodiment of the present invention, the limiting portion 13 of the sleeve 1 may be at least all corners 13b provided on the bottom end surface of the sleeve 1, so that the bottom end surface of the sleeve 1 is non-circular. The locking member 51 of the anti-loosening sleeve group 5 may be provided with a clamping tube hole 513. The sectional shape of the clamping tube hole 513 is non-circular and preferably matches the shape of the bottom end surface of the sleeve 1. According to this, the card holder 51 can be fitted through the card tube hole 513 to the outer peripheral surface of the bottom end of the sleeve 1, and the card holder 51 can hardly rotate relative to the tube 1 to stably connect the anti-rotation member 53. The same effect can be achieved by the anti-rotation member 53 restricting the screw member 52 from rotating relative to the mandrel 4.
其中，為確保該螺固件52能穩固壓抵該卡固件51，本實施例的防鬆套組5較佳另設有一墊片55，該墊片55可設於該卡固件51與該螺固件52之間，使該螺固件52可穩固壓抵該墊片55，並藉由該墊片55 間接地壓抵該卡固件51，以避免該螺固件52太小時，該螺固件52的局部或全部會直接落入該卡管孔513內而無法穩固壓抵該卡固件51。 Among them, in order to ensure that the screw fastener 52 can be firmly pressed against the card fastener 51, the anti-loosening sleeve set 5 of this embodiment is preferably provided with a spacer 55, which can be provided on the card fastener 51 and the screw fastener. 52, so that the screw member 52 can be firmly pressed against the washer 55, and the washer 55 Indirectly, the card holder 51 is pressed against the card holder 51 to prevent the screw member 52 from being too small. Part or all of the screw member 52 may directly fall into the card tube hole 513 and cannot be pressed firmly against the card holder 51.
綜上所述，本發明的吊扇馬達，可藉由設置防鬆套組，防止吊扇運作時的震動導致螺合於芯軸的螺固件鬆動，達到提升使用安全性等功效。 To sum up, the ceiling fan motor of the present invention can prevent the vibration of the ceiling fan from loosening due to the vibration of the ceiling fan by setting a loosening prevention set, thereby improving the use safety and the like.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed using the above-mentioned preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention. The technical scope protected by the invention, so the scope of protection of the present invention shall be determined by the scope of the appended patent application.
