如圖2所示，每一所述第一結合機構43是朝向該固定框5之基板51的方向凸起，呈空心剖半柱狀而形成插槽的形態，每一所述第一結合機構43具有一圍繞壁431並圍繞出一卡掣空間432，該卡掣空間432與外界連通並形成一開口。另外，該圍繞壁431上形成有一凹槽433。As shown in FIG. 2, each of the first coupling mechanisms 43 is convex toward the base plate 51 of the fixed frame 5, and is hollow and half-column shaped to form a slot.

In order to form a space for the side wall 42 of the back frame 4 to be accommodated, the side wall 42 of the back frame 4 and the side plate 52 of the fixed frame 5 approximately form a coplanar plane.

參閱圖3，該光學單元3包含一導光板31，及一設置於該導光板31之入光側的發光機構32。該框架結構2的組裝方式，是將該固定框5相對於該背框4沿一第一方向X對位後，再沿一第二方向Y卡合，而該第一方向X與該第二方向Y互相垂直。其中，該第一方向X是平行於該背框4之該本體41的厚度方向，該第二方向Y則是平行於該背框4之該側壁42的厚度方向，而因為該側壁42環繞該本體41之周緣，因此，該側壁42可以區分為左右相對側與上下相對側，該第二方向Y可以依需求設計為左右相對側之該側壁42的厚度方向，或是上下相對側之該側壁42的厚度方向。更詳細地說，本較佳實施例於組裝時，會先將該光學單元3由上而下地（如圖所示是沿著該第一方向X）放置於該背框4的該本體41上，接著安裝該固定框5，使該固定框5的該側板52的該頂抵部521，以該第一方向X沿著該背框4的該側壁42向下移動，當該頂抵部521抵接於該背框4的本體41上，即完成對位動作。此外，本發明的發光機構32可以是側入式光條或者直下式發光二極體模組。Referring to FIG. 3, the optical unit 3 includes a light guide plate 31 and a light-emitting mechanism 32 disposed on the light-incident side of the light guide plate 31. The frame structure 2 is assembled by aligning the fixing frame 5 with respect to the back frame 4 in a first direction X, and then engaging in a second direction Y, and the first direction X is aligned with the second direction X. The directions Y are perpendicular to each other. Wherein, the first direction X is parallel to the thickness direction of the main body 41 of the back frame 4, and the second direction Y is parallel to the thickness direction of the side wall 42 of the back frame 4, and because the side wall 42 surrounds the The periphery of the main body 41, therefore, the side wall 42 can be divided into left and right opposite sides and upper and lower opposite sides. The second direction Y can be designed as the thickness direction of the side wall 42 on the left and right opposite sides, or the side wall on the upper and lower opposite sides. 42 of the thickness direction. In more detail, during assembly of the preferred embodiment, the optical unit 3 is first placed on the main body 41 of the back frame 4 from top to bottom (as shown in the first direction X) , Then install the fixing frame 5 so that the abutting portion 521 of the side plate 52 of the fixing frame 5 moves downward along the side wall 42 of the back frame 4 in the first direction X, when the abutting portion 521 Abutting on the main body 41 of the back frame 4 completes the alignment action. In addition, the light-emitting mechanism 32 of the present invention may be an edge-type light bar or a direct-type light-emitting diode module.

參閱圖4並配合圖3，接下來，將所述第二結合機構53相對於所述第一結合機構43沿該第二方向Y移動，使所述第二結合機構53與所述第一結合機構43互相干涉而卡合。也就是說，所述第二結合機構53相對於所述第一結合機構43沿該第二方向Y移動時，每一第二結合機構53的該卡合片532的局部，是經由每一第一結合機構43的該開口進入並被限位於該卡掣空間432內，且當每一第二結合機構53持續沿該第二方向Y移動，待該限位柱531被定位於每一第一結合機構43的該凹槽433內時，即完成卡合動作。4 and in conjunction with FIG. 3, next, move the second coupling mechanism 53 relative to the first coupling mechanism 43 along the second direction Y, so that the second coupling mechanism 53 and the first coupling The mechanisms 43 interfere with each other and engage. That is to say, when the second coupling mechanism 53 moves in the second direction Y relative to the first coupling mechanism 43, a part of the engaging piece 532 of each second coupling mechanism 53 passes through each first coupling mechanism. The opening of a coupling mechanism 43 enters and is confined in the detent space 432, and when each second coupling mechanism 53 continues to move in the second direction Y, wait for the limit post 531 to be positioned at each first When the groove 433 of the coupling mechanism 43 is inside, the engaging action is completed.

另外，要特別說明的是，該側板52的該頂抵部521與該側壁42形成有一間距D1，而該第一結合機構43與該第二結合機構53沿第二方向Y上具有一干涉寬度D2，該間距D1是大於等於該干涉寬度D2。因此，當該側板52的該頂抵部521，沿著該側壁42向下移動時，所述第二結合機構53的該卡合片532不會與所述第一結合機構43的圍繞壁431互相干涉，而能順利完成對位動作。再者，本實施例中，所述固定框5相對於該背框4在第一方向X上，是藉由該頂抵部521、該抵靠部523及該第二結合機構53被限位，在第二方向Y上則是藉由該第一結合機構43被限位，據此達到互相干涉的定位效果。In addition, it should be particularly noted that the abutment portion 521 of the side plate 52 and the side wall 42 form a distance D1, and the first coupling mechanism 43 and the second coupling mechanism 53 have an interference width along the second direction Y D2, the distance D1 is greater than or equal to the interference width D2. Therefore, when the abutting portion 521 of the side plate 52 moves downward along the side wall 42, the engaging piece 532 of the second coupling mechanism 53 will not interact with the surrounding wall 431 of the first coupling mechanism 43. Interference with each other, and can successfully complete the alignment action. Furthermore, in this embodiment, the fixed frame 5 is in the first direction X relative to the back frame 4, and is restricted by the abutting portion 521, the abutting portion 523, and the second coupling mechanism 53 , In the second direction Y, the position is restricted by the first coupling mechanism 43, thereby achieving the positioning effect of mutual interference.

參閱圖5，當本發明背光模組組合完成後，再加上一顯示面板6，即成為一顯示裝置。其中，如圖2所示，該基板51與該側板52的限位部522共同圍繞出的該容置空間54，就是用來容置並限位該顯示面板6。Referring to FIG. 5, after the backlight module assembly of the present invention is completed, a display panel 6 is added to form a display device. Wherein, as shown in FIG. 2, the accommodating space 54 enclosed by the substrate 51 and the limiting portion 522 of the side plate 52 is used to accommodate and limit the display panel 6.

需特別說明的是，所述固定框5可以是以下四種型態：(1) 相對於該背框4周緣環繞設置的封閉框、(2)相對於該背框4周緣的其中三個邊的U型框、(3) 相對於該背框4周緣的其中兩個邊的L型框、或者是(4)相對於該背框4周緣的其中一個邊的邊框。不論固定框5為前述何種型態，該背框4的側壁42包含有至少一個側壁部421用以對應設置前述任一種型態的固定框5。舉例而言，該側壁42具有兩個互相平行的側壁部421或兩個互相垂直的側壁部421（如圖2所示），可依照需求相對於該背框4的側壁部421對應設置複數個所述邊框、或對應型態的L型框、U型框或封閉框。在圖2所示的實施例中，所述固定框5為一個邊框，係相對於背框4的一個側壁部421設置，在靠近其中一側壁部421的所述第一結合機構43的開口是朝向同一方向，所述固定框5便可利用前述對位及卡合動作完成定位。在其他實施例中，所述固定框5是其他三種型態（口字封閉框、U型框或Ｌ型框），此時，該側壁42的兩個互相垂直的側壁部421之中，在靠近其中一側壁部421的所述第一結合機構43的開口，與靠近另一側壁部421的所述第一結合機構43的開口是朝向不同方向。當所述第一結合機構43的開口方向不同，由於該固定框5是以具有撓性材料製成，因此可以如圖6所示，藉由其可撓特性將第二結合機構53的限位柱531扳折後蓄積一股尚未釋放的回彈力，再將卡合片532***第一結合機構43的卡掣空間432中，此時限位柱531所蓄積的回彈力就可以予以釋放，而使得限位柱531能夠進入該凹槽433內完成卡合動作。另一方面，除了兩個互相垂直的側壁部421之外，針對兩個互相平行的側壁部421的情況，在靠近其中一側壁部421的所述第一結合機構43的開口，與靠近另一側壁部421的所述第一結合機構43的開口，亦可選擇為同一方向或不同方向，其對位及卡合動作亦如上述方式執行，在此容不贅述。It should be particularly noted that the fixed frame 5 can be of the following four types: (1) a closed frame arranged around the periphery of the back frame 4, (2) three sides of the periphery of the back frame 4 The U-shaped frame of (3) the L-shaped frame on two sides of the periphery of the back frame 4, or (4) the frame of one of the sides of the periphery of the back frame 4. Regardless of the type of the fixing frame 5 described above, the side wall 42 of the back frame 4 includes at least one side wall portion 421 for correspondingly setting any type of the fixing frame 5 described above. For example, the side wall 42 has two parallel side wall portions 421 or two mutually perpendicular side wall portions 421 (as shown in FIG. 2), and a plurality of corresponding side wall portions 421 of the back frame 4 can be provided according to requirements. The frame, or a corresponding type of L-shaped frame, U-shaped frame, or closed frame. In the embodiment shown in FIG. 2, the fixed frame 5 is a frame, which is arranged relative to a side wall portion 421 of the back frame 4, and the opening of the first coupling mechanism 43 near one of the side wall portions 421 is Facing the same direction, the fixed frame 5 can be positioned using the aforementioned positioning and engaging actions. In other embodiments, the fixed frame 5 is of the other three types (a closed frame, a U-shaped frame or an L-shaped frame). At this time, among the two mutually perpendicular sidewall portions 421 of the sidewall 42, The opening of the first coupling mechanism 43 near one of the side wall portions 421 and the opening of the first coupling mechanism 43 near the other side wall portion 421 face different directions. When the opening directions of the first coupling mechanism 43 are different, since the fixing frame 5 is made of a flexible material, the second coupling mechanism 53 can be limited by its flexibility as shown in FIG. After the column 531 is folded, an unreleased resilience is accumulated, and then the engaging piece 532 is inserted into the latching space 432 of the first coupling mechanism 43. At this time, the resilience accumulated by the limiting column 531 can be released, so that The limiting post 531 can enter the groove 433 to complete the engagement action. On the other hand, in addition to two mutually perpendicular side wall portions 421, in the case of two mutually parallel side wall portions 421, the opening of the first coupling mechanism 43 near one of the side wall portions 421 is different from the opening near the other side wall portion 421. The openings of the first coupling mechanism 43 of the side wall portion 421 can also be selected in the same direction or different directions, and the alignment and engagement actions are also performed in the same manner as described above, which will not be repeated here.

二、簡化組裝程序：承上所述，當該背框4與該固定框5的對稱兩側皆利用卡合的方式進行組裝，就可以取消現有技術中利用膠帶黏合該背框4與該固定框5的組裝方式，進而簡化組裝程序，同時更能應用於窄邊框的機型上。更詳言之，如欲重工需求時，因本發明是利用卡合方式組裝，故重新拆卸時較不容易傷及其他構件（例如光學膜片或導光板）。2. Simplification of the assembly procedure: As mentioned above, when the symmetrical sides of the back frame 4 and the fixed frame 5 are assembled in a snap-fit manner, the use of adhesive tape to bond the back frame 4 and the fixing in the prior art can be eliminated The assembly method of the frame 5 further simplifies the assembly procedure and can be applied to models with narrow bezels at the same time. In more detail, for heavy work requirements, because the present invention is assembled by a snap-fit method, it is less likely to damage other components (such as optical films or light guide plates) during re-disassembly.

三、因應自動化趨勢：現今顯示裝置的機種越來越朝向窄框化發展，因此組裝精度的需求不斷提升，以人工方式組裝可能無法滿足精準度之要求。透過本發明中該背框4與該固定框5的結構設計，使得背光模組中各元件的組合可以直上直下進行縱向的疊合組裝，將可應用於自動化組裝的產線上。更詳言之，本發明背光模組不僅在人工組裝時較為容易；本發明背光模組亦適用於自動化組裝，對於機械手臂而言，習用U形框架組裝其他構件時不僅容易發生干涉且對位不易，藉由前述對位動作與卡合動作的一維操作是相對容易且準確的。3. In response to the trend of automation: Nowadays, the types of display devices are becoming more and more narrow-framed. Therefore, the demand for assembly accuracy continues to increase, and manual assembly may not meet the accuracy requirements. Through the structural design of the back frame 4 and the fixing frame 5 in the present invention, the combination of the components in the backlight module can be vertically stacked and assembled vertically, which can be applied to the production line of automated assembly. In more detail, the backlight module of the present invention is not only easier to assemble manually; the backlight module of the present invention is also suitable for automated assembly. For the robot arm, the conventional U-shaped frame is not only prone to interference and alignment when assembling other components. It is not easy. The one-dimensional operation by the aforementioned alignment action and the engagement action is relatively easy and accurate.
