本創作上述之實施方式與已知先前技術相較,至少具有以下優點:The above-described embodiments of the present invention have at least the following advantages over the known prior art:
(1)由於偏心部具有第二中心線,而第二中心線平行於第一中心線。故此,當本體部藉由第二銜接部繞著第一中心線相對底板轉動時,偏心部亦會以第一中心線為軸心隨本體部轉動。因此,藉由偏心部穿過穿孔,當偏心部以第一中心線為軸心轉動時,偏心部與穿孔間會產生相對運動, 使得光學膜片得以拉緊。如此一來,光學膜片與底板之間的分隔距離能夠保持的同時,光學膜片的組裝程序也能透過分隔銷的轉動而簡單地完成,即先將光學膜片預組裝後,再進行拉緊動作,與習知先拉緊光學膜片之後再進行組裝的方式不同,因此可有效避免組裝不良的情形發生。(1) Since the eccentric portion has a second center line, and the second center line is parallel to the first center line. Therefore, when the body portion is rotated relative to the bottom plate by the second connecting portion around the first center line, the eccentric portion also rotates with the body portion with the first center line as an axis. Therefore, when the eccentric portion passes through the through hole, when the eccentric portion is rotated about the first center line, a relative movement occurs between the eccentric portion and the through hole. The optical film is tightened. In this way, the separation distance between the optical film and the bottom plate can be maintained, and the assembly process of the optical film can also be simply completed by the rotation of the separation pin, that is, the optical film is pre-assembled and then pulled. The tightening action is different from the conventional method of tightening the optical film and then assembling it, so that the assembly failure can be effectively avoided.
(2)由於偏心部呈柱狀,並且偏心部的外徑小於穿孔的孔徑,因此,偏心部穿過穿孔的過程能夠簡易地進行。(2) Since the eccentric portion has a columnar shape and the outer diameter of the eccentric portion is smaller than the diameter of the perforation, the process of the eccentric portion passing through the perforation can be easily performed.
(3)彈性臂能夠沿長圓孔較長的長軸方向相對軸體張開,並且卡合於長圓孔的兩端。在這狀況下,由於長圓孔內没有更大的長度空間讓彈性臂進一步張開,因此,彈性臂能夠處於穩定的狀態。如此一來,如果没有使用者所施加的外力,分隔銷在轉動後亦不會自行復位至轉動前的位置,使得分隔銷相對底板的位置得以固定。(3) The elastic arm can be opened relative to the shaft body along the long axis direction of the long circular hole, and is engaged with both ends of the long round hole. In this case, since the elastic arm is further opened due to the absence of a larger length space in the oblong hole, the elastic arm can be in a stable state. In this way, if there is no external force applied by the user, the partition pin does not reset to the position before the rotation after the rotation, so that the position of the partition pin relative to the bottom plate is fixed.

FIG. 1A is a partial cross-sectional side view of the backlight module 100 according to the first embodiment of the present invention. Figure 1B shows A partial cross-sectional side view of the backlight module 100 of FIG. 1A in which the spacer pin 130 is rotated and the eccentric portion 133 is engaged with the through hole 120a. FIG. 2 is a perspective view showing the partition pin 130 of the backlight module 100 of FIG. 1A. As shown in FIGS. 1A-2, a backlight module 100 includes a bottom plate 110, an optical film 120, and a partition pin 130. The bottom plate 110 has a first engaging portion 111. The optical film 120 has a perforation 120a, and the optical film 120 is made of an elastic material, but the creation is not limited thereto. The partition pin 130 includes a second engaging portion 131 , a body portion 132 , an eccentric portion 133 , and a first abutting portion 134 . The second engaging portion 131 is rotatably engaged with the first engaging portion 111. The body portion 132 is connected to the second connecting portion 131 and has a first center line CL1. The body portion 132 is rotatable relative to the bottom plate 110 by the second connecting portion 131 with the first center line CL1 as an axis. The eccentric portion 133 is coupled to the body portion 132 and has a second center line CL2 parallel to the first center line CL1, wherein the eccentric portion 133 passes through the through hole 120a. After the eccentric portion 133 is rotated with the body portion 132, the eccentric portion 133 is engaged with the through hole 120a. The first abutting portion 134 is connected to the interface between the body portion 132 and the eccentric portion 133 and abuts against the optical film 120 to support and hold the optical film 120. In the present embodiment, the shape of the through hole 120a may be circular, square or elliptical in consideration of ease of assembly, but the present invention is not limited thereto.
具體地說,當本體部132藉由第二銜接部131繞著第一中心線CL1相對底板110轉動時,偏心部133亦會以第一中心線CL1為軸心隨本體部132轉動。光學膜片120與底板110之間的分隔距離,需要符合背光模組100光學設計的技術要求。在本實施方式中,穿孔120a位於光學膜片120近邊緣的位置。在分隔銷130相對底板110轉動前, 穿孔120a的位置對應偏心部133。因此,藉由偏心部133穿過穿孔120a,當偏心部133以第一中心線CL1為軸心轉動時,偏心部133與穿孔120a間會產生相對運動,使得光學膜片120得以拉緊。如此一來,光學膜片120與底板110之間的分隔距離能夠保持的同時,光學膜片120的組裝程序也能透過分隔銷130的轉動而簡單地完成,即先將光學膜片120預組裝後,再進行拉緊動作,與習知先拉緊光學膜片120之後再進行組裝的方式不同,因此可有效避免組裝不良的情形發生。另外,分隔銷130可為一體成形的結構,但本創作並不以此為限。Specifically, when the body portion 132 is rotated relative to the bottom plate 110 about the first center line CL1 by the second engaging portion 131, the eccentric portion 133 also rotates with the body portion 132 with the first center line CL1 as an axis. The separation distance between the optical film 120 and the bottom plate 110 needs to meet the technical requirements of the optical design of the backlight module 100. In the present embodiment, the perforations 120a are located at the near edge of the optical film 120. Before the partition pin 130 rotates relative to the bottom plate 110, The position of the through hole 120a corresponds to the eccentric portion 133. Therefore, when the eccentric portion 133 passes through the through hole 120a, when the eccentric portion 133 is rotated about the first center line CL1, a relative movement between the eccentric portion 133 and the through hole 120a occurs, so that the optical film 120 is tightened. In this way, while the separation distance between the optical film 120 and the bottom plate 110 can be maintained, the assembly process of the optical film 120 can also be easily accomplished by the rotation of the partition pin 130, that is, the optical film 120 is pre-assembled. Thereafter, the tightening operation is performed, and the method of assembling the optical film 120 after the optical film 120 is first tightened is different, so that the assembly failure can be effectively prevented. In addition, the partition pin 130 may be an integrally formed structure, but the present invention is not limited thereto.
進一步來說,為了加強穩固光學膜片120與底板110之間的分隔距離,分隔銷130還包含第二抵靠部135。第二抵靠部135連接於本體部132與第二銜接部131的交界處,用以抵靠底板110。Further, in order to strengthen the separation distance between the optical film 120 and the bottom plate 110, the partition pin 130 further includes a second abutting portion 135. The second abutting portion 135 is connected to the boundary between the body portion 132 and the second engaging portion 131 for abutting against the bottom plate 110.
如第1A~2圖所示,偏心部具有溝槽133a1,溝槽133a1鄰接第一抵靠部134,並且光學膜片120卡合於溝槽133a1。故此,光學膜片120在組裝至分隔銷130後不會朝遠離第一抵靠部134的方向脫離。As shown in FIGS. 1A to 2, the eccentric portion has a groove 133a1, the groove 133a1 is adjacent to the first abutting portion 134, and the optical film 120 is engaged with the groove 133a1. Therefore, the optical film 120 does not detach away from the first abutting portion 134 after being assembled to the partition pin 130.
在光學膜片120組裝至分隔銷130前,亦即在分隔銷130相對底板110轉動前,溝槽133a1實質上朝向光學膜片120的中央。在本實施方式中,偏心部133呈柱狀,並且偏心部133的外徑D2小於穿孔120a的孔徑D1。如此一來,偏心部133穿過穿孔120a的過程能夠簡易地進行。Before the optical film 120 is assembled to the partition pin 130, that is, before the partition pin 130 is rotated relative to the bottom plate 110, the groove 133a1 substantially faces the center of the optical film 120. In the present embodiment, the eccentric portion 133 has a columnar shape, and the outer diameter D2 of the eccentric portion 133 is smaller than the diameter D1 of the through hole 120a. In this way, the process of the eccentric portion 133 passing through the through hole 120a can be easily performed.
再者,偏心部133的第二中心線CL2位於第一中 心線CL1與溝槽133a1之間。也就是說,在分隔銷130相對底板110轉動前,溝槽133a1朝向光學膜片120的中央,而光學膜片120也不會卡合於溝槽133a1。然而,在分隔銷130相對底板110轉動後,即偏心部133以第一中心線CL1為軸心隨本體部132轉動後,溝槽133a1會轉動至遠離光學膜片120中央的位置,使得穿孔120a的位置被拉扯,而光學膜片120更得以被偏心部133拉緊,並卡合於溝槽133a1。Furthermore, the second center line CL2 of the eccentric portion 133 is located in the first Between the core line CL1 and the groove 133a1. That is, before the separation pin 130 is rotated relative to the bottom plate 110, the groove 133a1 faces the center of the optical film 120, and the optical film 120 does not engage with the groove 133a1. However, after the partition pin 130 is rotated relative to the bottom plate 110, that is, after the eccentric portion 133 is rotated with the main body portion 132 with the first center line CL1 as the axis, the groove 133a1 is rotated to a position away from the center of the optical film 120, so that the through hole 120a The position is pulled, and the optical film 120 is further tightened by the eccentric portion 133 and engaged with the groove 133a1.
請參照第3圖,其繪示第1A圖之背光模組100的局部剖面側視圖。如第1A~1B、3圖所示,第一銜接部111為長圓孔,第二銜接部131則包含軸體131a與兩彈性臂131b。軸體131a連接本體部132,並穿過長圓孔。彈性臂131b連接軸體131a,並分別延伸至軸體131a的兩側,彈性臂131b卡合於長圓孔的兩端。如此一來,在分隔銷130相對底板110轉動前,彈性臂131b能夠沿長圓孔較長的長軸方向相對軸體131a張開,並且卡合於長圓孔的兩端。在這狀況下,由於長圓孔內没有更大的長度空間讓彈性臂131b進一步張開,因此,彈性臂131b能夠處於穩定的狀態,分隔銷130亦能夠保持與底板110相對不轉動。當使用者使分隔銷130相對底板110轉動時,第二銜接部131會於長圓孔內轉動。隨著第二銜接部131於長圓孔內的轉動,彈性臂131b會朝軸體131a的方向被壓縮,並且彈性臂131b會儲存一位能,直至彈性臂131b轉動至長圓孔較短的短軸。當彈性臂131b通過長圓孔的短軸後,彈性臂 131b將釋放儲存的位能,並且彈性臂131b能夠相對軸體131a張開,直至彈性臂131b再次轉動至長圓孔的長軸。此時,由於長圓孔內没有更大的長度空間讓彈性臂131b進一步張開,因此,彈性臂131b能夠再次處於穩定的狀態。換句話說,基於彈性臂131b壓縮及張開的動作,分隔銷130從轉動前的位置轉動至轉動後的位置,需要以一外力帶動。如果没有使用者所施加的外力,分隔銷130在轉動後亦不會自行復位至轉動前的位置,使得分隔銷130相對底板110的位置得以固定。Please refer to FIG. 3 , which is a partial cross-sectional side view of the backlight module 100 of FIG. 1A . As shown in FIGS. 1A to 1B and 3, the first engaging portion 111 is an oblong hole, and the second engaging portion 131 includes a shaft body 131a and two elastic arms 131b. The shaft body 131a is coupled to the body portion 132 and passes through the oblong hole. The elastic arm 131b is coupled to the shaft body 131a and extends to both sides of the shaft body 131a, and the elastic arm 131b is engaged with both ends of the oblong hole. In this way, before the partition pin 130 rotates relative to the bottom plate 110, the elastic arm 131b can be opened relative to the shaft body 131a along the long axis direction of the long circular hole, and is engaged with both ends of the oblong hole. In this case, since the elastic arm 131b is further opened due to the absence of a larger length space in the oblong hole, the elastic arm 131b can be in a stable state, and the partition pin 130 can also remain relatively rotatable with the bottom plate 110. When the user rotates the partition pin 130 relative to the bottom plate 110, the second engaging portion 131 rotates within the oblong hole. As the second engaging portion 131 rotates in the oblong hole, the elastic arm 131b is compressed in the direction of the shaft 131a, and the elastic arm 131b stores one bit until the elastic arm 131b rotates to the short axis of the long circular hole. . When the elastic arm 131b passes through the short axis of the oblong hole, the elastic arm The 131b will release the stored potential energy, and the elastic arm 131b can be opened relative to the shaft 131a until the elastic arm 131b is rotated again to the long axis of the oblong hole. At this time, since the elastic arm 131b is further opened due to the absence of a larger length space in the oblong hole, the elastic arm 131b can be in a stable state again. In other words, based on the action of the compression and opening of the elastic arm 131b, the partition pin 130 is rotated from the position before the rotation to the position after the rotation, and needs to be driven by an external force. If there is no external force applied by the user, the partition pin 130 does not reset itself to the position before the rotation after the rotation, so that the position of the partition pin 130 with respect to the bottom plate 110 is fixed.
第二實施方式Second embodiment
請參照第4~6圖。第4圖繪示依照本創作第二實施方式之背光模組200的局部剖面側視圖。第5圖繪示第4圖之背光模組200之分隔銷230的立體示意圖。第6圖繪示第4圖之背光模組200之分隔銷230的立體爆炸圖。如第4~6圖所示,背光模組200包含底板210、光學膜片220與分隔銷230。底板210具有第一銜接部211。光學膜片220具有穿孔220a。分隔銷230包含第二銜接部231、本體部232、偏心部233與第一抵靠部234。第二銜接部231銜接第一銜接部211。本體部232連接第二銜接部231,並具有第一中心線CL1。偏心部233可裝拆地連接本體部232。偏心部233可以第一中心線CL1為軸心相對本體部232轉動,並具有第二中心線CL2平行於第一中心線CL1,其中偏心部233穿過穿孔220a,並與穿孔220a卡合。第一抵靠部234連接本體部232,並抵靠偏心部233與光學膜片220, 藉以支撐及夾持光學膜片220。Please refer to pictures 4~6. FIG. 4 is a partial cross-sectional side view of the backlight module 200 according to the second embodiment of the present invention. FIG. 5 is a perspective view showing the partition pin 230 of the backlight module 200 of FIG. 4 . FIG. 6 is a perspective exploded view of the partition pin 230 of the backlight module 200 of FIG. 4. As shown in FIGS. 4-6, the backlight module 200 includes a bottom plate 210, an optical film 220, and a partition pin 230. The bottom plate 210 has a first engaging portion 211. The optical film 220 has a perforation 220a. The partition pin 230 includes a second engaging portion 231 , a body portion 232 , an eccentric portion 233 , and a first abutting portion 234 . The second connecting portion 231 is coupled to the first connecting portion 211 . The body portion 232 is connected to the second engaging portion 231 and has a first center line CL1. The eccentric portion 233 is detachably coupled to the body portion 232. The eccentric portion 233 is rotatable relative to the body portion 232 with the first center line CL1 as an axis, and has a second center line CL2 parallel to the first center line CL1, wherein the eccentric portion 233 passes through the through hole 220a and is engaged with the through hole 220a. The first abutting portion 234 is coupled to the body portion 232 and abuts the eccentric portion 233 and the optical film 220. Thereby supporting and clamping the optical film 220.
如第4、6圖所示,本體部232包含轉動柱232a。轉動柱232a實質上沿著第一中心線CL1延伸,偏心部233具有轉動孔233d供轉動柱232a插入,並與轉動柱232a呈轉動配合,並且轉動孔233d的圓心偏離第二中心線CL2。更具體地說,偏心部233能夠繞著第一中心線CL1相對本體部232轉動。因此,藉由偏心部233穿過穿孔220a,穿孔220a的位置也會隨偏心部233以第一中心線CL1為軸心轉動而被拉扯,使得光學膜片220得以拉緊。如此一來,光學膜片220的組裝程序亦能夠透過偏心部233的轉動而簡單地完成,也避免了習知以徒手方式組裝光學膜片220所產生的組裝不良機會。As shown in Figures 4 and 6, the body portion 232 includes a rotating post 232a. The rotating post 232a extends substantially along the first center line CL1. The eccentric portion 233 has a rotating hole 233d for the rotation of the rotating post 232a, and is in rotational engagement with the rotating post 232a, and the center of the rotating hole 233d is offset from the second center line CL2. More specifically, the eccentric portion 233 is rotatable relative to the body portion 232 about the first center line CL1. Therefore, by the eccentric portion 233 passing through the through hole 220a, the position of the through hole 220a is also pulled as the eccentric portion 233 is pivoted about the first center line CL1, so that the optical film 220 is tightened. As a result, the assembly process of the optical film 220 can be easily performed by the rotation of the eccentric portion 233, and the chance of assembly failure caused by the conventional assembly of the optical film 220 by hand is also avoided.
請參照第7圖,其繪示第4圖之背光模組200之分隔銷230的上視圖。為了進一步導引偏心部233相對本體部232的轉動,如第5~7圖所示,第一抵靠部234具有鎖固槽234a。鎖固槽234a以第一中心線CL1為圓心沿周向延伸,鎖固槽234a具有第一端234a1與第二端234a2,第一中心線CL1位於第一端234a1與第二端234a2之間。偏心部233則包含轉動帽233a與鎖固臂233b。轉動帽233a穿過穿孔220a,並與穿孔220a卡合。鎖固臂233b連接轉動帽233a,並穿入鎖固槽234a,其中在偏心部233相對本體部232轉動期間,鎖固臂233b滑動於鎖固槽234a的兩端之間。Please refer to FIG. 7 , which is a top view of the partition pin 230 of the backlight module 200 of FIG. 4 . In order to further guide the rotation of the eccentric portion 233 with respect to the body portion 232, as shown in FIGS. 5 to 7, the first abutting portion 234 has a locking groove 234a. The locking groove 234a extends circumferentially with the first center line CL1 as a center. The locking groove 234a has a first end 234a1 and a second end 234a2. The first center line CL1 is located between the first end 234a1 and the second end 234a2. The eccentric portion 233 includes a rotating cap 233a and a locking arm 233b. The rotating cap 233a passes through the through hole 220a and is engaged with the through hole 220a. The locking arm 233b is coupled to the rotating cap 233a and penetrates into the locking groove 234a. During the rotation of the eccentric portion 233 relative to the body portion 232, the locking arm 233b slides between the two ends of the locking groove 234a.
進一步來說,如第5~7圖所示,鎖固槽234a的寬 度B由第一端234a1朝向第二端234a2漸減,並且鎖固槽234a鄰近第二端234a2的內壁W與鎖固臂233b呈緊配合。換句話說,當鎖固臂233b從第一端234a1朝向第二端234a2滑動時,即偏心部233轉動而拉緊光學膜片220時,鎖固臂233b與鄰近第二端234a2的內壁W呈緊配合。如此一來,當鎖固臂233b到達第二端234a2時,鎖固臂233b受到內壁W的緊配合而不會輕易地脫離第二端234a2,使得偏心部233在轉動而拉緊光學膜片220後不會鬆脫。Further, as shown in Figures 5-7, the width of the locking groove 234a is The degree B is gradually decreased from the first end 234a1 toward the second end 234a2, and the locking groove 234a is in close fitting with the locking arm 233b adjacent to the inner wall W of the second end 234a2. In other words, when the locking arm 233b slides from the first end 234a1 toward the second end 234a2, that is, when the eccentric portion 233 is rotated to tighten the optical film 220, the locking arm 233b and the inner wall W adjacent to the second end 234a2 Tight fit. In this way, when the locking arm 233b reaches the second end 234a2, the locking arm 233b is tightly engaged by the inner wall W without being easily disengaged from the second end 234a2, so that the eccentric portion 233 is rotated to tighten the optical film. After 220 will not be loose.
如第4、6~7圖所示,偏心部233還包含卡合頭233c。鎖固臂233b連接於轉動帽233a與卡合頭233c之間,並穿過鎖固槽234a。並且,卡合頭233c的外徑D3大於鎖固槽234a的寬度B,使得卡合頭233c無法通過鎖固槽234a。如此一來,由於卡合頭233c無法通過鎖固槽234a,偏心部233也不會朝遠離第一抵靠部234的方向脫離。As shown in FIGS. 4 and 6 to 7, the eccentric portion 233 further includes an engaging head 233c. The locking arm 233b is connected between the rotating cap 233a and the engaging head 233c and passes through the locking groove 234a. Moreover, the outer diameter D3 of the engaging head 233c is larger than the width B of the locking groove 234a, so that the engaging head 233c cannot pass through the locking groove 234a. As a result, since the engaging head 233c cannot pass through the locking groove 234a, the eccentric portion 233 does not come out in a direction away from the first abutting portion 234.
總括來說,第二實施方式與第一實施方式的不同點在於:第二實施方式的分隔銷230為分離式結構,即偏心部233與本體部232能夠相對轉動,而第二銜接部231不轉動地與第一銜接部211相銜接,且由於本體部232連接第二銜接部231,故本體部232也不會相對底板210轉動。也就是說,偏心部233能夠與底板210相對轉動。In summary, the second embodiment is different from the first embodiment in that the partition pin 230 of the second embodiment is of a separate structure, that is, the eccentric portion 233 and the body portion 232 are relatively rotatable, and the second engaging portion 231 is not The first engaging portion 211 is rotatably engaged, and since the main portion 232 is connected to the second engaging portion 231, the main body portion 232 does not rotate relative to the bottom plate 210. That is, the eccentric portion 233 is rotatable relative to the bottom plate 210.
至於其他相關的結構與操作細節,由於均與第一實施方式相同,因此不再重複贅述之。As for other related structural and operational details, since they are all the same as the first embodiment, the description thereof will not be repeated.
第三實施方式Third embodiment
請參照第8~9圖。第8圖繪示依照本創作第三實 施方式之背光模組300的局部剖面側視圖。第9圖繪示第8圖之背光模組300之分隔銷330的立體爆炸圖。如第8~9圖所示,分隔銷330之本體部332包含轉動孔332a。轉動孔332a實質上沿著第一中心線CL1延伸,偏心部333具有轉動柱333d插入轉動孔332a,並與轉動孔332a呈轉動配合,並且轉動柱333d的軸心偏離第二中心線CL2。也就是說,偏心部333以第一中心線CL1為軸心轉動。因此,藉由偏心部333穿過穿孔320a,穿孔320a也會隨偏心部333以第一中心線CL1為軸心轉動而被拉扯,使得光學膜片320得以拉緊。如此一來,光學膜片320的組裝程序亦能夠透過偏心部333的轉動而簡單地完成,也避免了習知以徒手方式組裝光學膜片320所產生的組裝不良機會。Please refer to pictures 8~9. Figure 8 shows the third real in accordance with this creation. A partial cross-sectional side view of the backlight module 300 of the embodiment. FIG. 9 is a perspective exploded view of the partition pin 330 of the backlight module 300 of FIG. 8. As shown in FIGS. 8 to 9, the body portion 332 of the partition pin 330 includes a rotation hole 332a. The rotating hole 332a extends substantially along the first center line CL1, and the eccentric portion 333 has the rotating post 333d inserted into the rotating hole 332a and is rotationally engaged with the rotating hole 332a, and the axis of the rotating post 333d is offset from the second center line CL2. That is, the eccentric portion 333 is rotated about the first center line CL1. Therefore, by the eccentric portion 333 passing through the through hole 320a, the through hole 320a is also pulled as the eccentric portion 333 is rotated about the first center line CL1, so that the optical film 320 is tightened. As a result, the assembly process of the optical film 320 can be easily accomplished by the rotation of the eccentric portion 333, and the chance of assembly failure caused by the conventional assembly of the optical film 320 by hand is avoided.
總括來說,第三實施方式與第二實施方式的不同點在於:第三實施方式的本體部332包含轉動孔332a,而偏心部333則具有轉動柱333d。In summary, the third embodiment is different from the second embodiment in that the body portion 332 of the third embodiment includes a rotation hole 332a, and the eccentric portion 333 has a rotation column 333d.
至於其他相關的結構與操作細節,由於均與第二實施方式相同,因此不再重複贅述之。As for other related structural and operational details, since they are all the same as the second embodiment, the description thereof will not be repeated.
綜上所述,本創作的技術方案與現有技術相比具有明顯的優點和有益效果。通過上述技術方案,可達到相當的技術進步,並具有產業上的廣泛利用價值,其至少具有以下優點:In summary, the technical solution of the present invention has obvious advantages and beneficial effects compared with the prior art. Through the above technical solutions, considerable technological progress can be achieved, and the industrial use value is widely utilized, which has at least the following advantages:
(1)由於偏心部具有第二中心線,而第二中心線平行於第一中心線。故此,當本體部藉由第二銜接部繞著第一中心線相對底板轉動時,偏心部亦會以第一中心線為軸心隨本 體部轉動。因此,藉由偏心部穿過穿孔,當偏心部以第一中心線為軸心轉動時,偏心部與穿孔間會產生相對運動,使得光學膜片得以拉緊。如此一來,光學膜片與底板之間的分隔距離能夠保持的同時,光學膜片的組裝程序也能透過分隔銷的轉動而簡單地完成,即先將光學膜片預組裝後,再進行拉緊動作,與習知先拉緊光學膜片之後再進行組裝的方式不同,因此可有效避免組裝不良的情形發生。(1) Since the eccentric portion has a second center line, and the second center line is parallel to the first center line. Therefore, when the body portion is rotated relative to the bottom plate by the second connecting portion around the first center line, the eccentric portion is also centered on the first center line. The body rotates. Therefore, when the eccentric portion passes through the through hole, when the eccentric portion is rotated about the first center line, a relative movement between the eccentric portion and the through hole is generated, so that the optical film is tightened. In this way, the separation distance between the optical film and the bottom plate can be maintained, and the assembly process of the optical film can also be simply completed by the rotation of the separation pin, that is, the optical film is pre-assembled and then pulled. The tightening action is different from the conventional method of tightening the optical film and then assembling it, so that the assembly failure can be effectively avoided.
(2)由於偏心部呈柱狀,並且偏心部的外徑小於穿孔的孔徑,因此,偏心部穿過穿孔的過程能夠簡易地進行。(2) Since the eccentric portion has a columnar shape and the outer diameter of the eccentric portion is smaller than the diameter of the perforation, the process of the eccentric portion passing through the perforation can be easily performed.
(3)彈性臂能夠沿長圓孔較長的長軸方向相對軸體張開,並且卡合於長圓孔的兩端。在這狀況下,由於長圓孔內没有更大的長度空間讓彈性臂進一步張開,因此,彈性臂能夠處於穩定的狀態。如此一來,如果没有使用者所施加的外力,分隔銷在轉動後亦不會自行復位至轉動前的位置,使得分隔銷相對底板的位置得以固定。(3) The elastic arm can be opened relative to the shaft body along the long axis direction of the long circular hole, and is engaged with both ends of the long round hole. In this case, since the elastic arm is further opened due to the absence of a larger length space in the oblong hole, the elastic arm can be in a stable state. In this way, if there is no external force applied by the user, the partition pin does not reset to the position before the rotation after the rotation, so that the position of the partition pin relative to the bottom plate is fixed.
雖然本創作已以實施方式揭露如上,然其並非用以限定本創作,任何熟習此技藝者,在不脫離本創作之精神和範圍內,當可作各種之更動與潤飾,因此本創作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 in the above embodiments, it is not intended to limit the present invention, and any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
