New description: [New technical field] The present invention relates to a backlight module, and more particularly to a frame of a backlight module. [Prior Art] Nowadays, liquid crystal display devices are widely used in electronic information products such as notebook computers, mobile phones, and personal digital assistants because of their advantages of being light, thin, and low in power consumption. The liquid crystal display device has a backlight module, and the backlight module comprises a frame body and an optical component assembled on the frame body. The frame body is generally composed of a metal back plate and a plastic frame. In order to reduce the thickness of the backlight module and increase the structural strength thereof, in the prior art, a plastic frame and a metal back plate are combined in a manner of in-mold injection molding. As shown in FIG. 5, it is a schematic structural view of a frame 10' of a conventional backlight module. The frame 10' includes a metal back plate 11' and a plastic frame 12'. The metal back plate 11' has a bottom plate 13' and a side plate 14' vertically connected to the bottom plate 13'. The opposite side plates 14' are respectively provided with a hole 15'. The plastic frame 12' is formed by injecting molten plastic from the broken hole 15' into the metal back plate 11' by using an in-mold injection molding technique, so that the metal back plate 11' and the plastic frame 12' are integrally formed, thereby making the metal The back plate 11' is firmly coupled to the plastic frame 12'. However, when the plastic frame 12' of the backlight module is injection molded, the molten plastic needs to pass through the through hole 15' of the M343174, which causes the molten plastic to be injected into the broken hole 15, which has a long holding time, thereby causing melting. The plastic has poor fluidity, which is unfavorable for the plastic frame 12 and is formed on the metal back plate U'. [New Content] - The purpose of this creation is to provide a frame for a backlight module that is molded on a metal back plate in view of the above-mentioned deficiencies of the prior art. In order to achieve the above object, the frame of the backlight module provided by the invention includes a metal back plate and a plastic frame. The metal back plate has a bottom plate, and a peripheral edge of the bottom plate vertically extends a plurality of side plates that are not connected to each other, and at least one side of the side plate is provided with a fastening structure. The plastic frame is formed on the inner side of the side plate of the metal back plate, and is formed with a fastening portion corresponding to the fastening structure, wherein the fastening portion is fitted with the fastening structure. According to the dream #, the metal back plate of the backlight module of the present invention is disposed on the side of the side plate, so that when the plastic frame is injection molded, the direction of the injection plastic is from top to bottom. From the bottom to the top or from the side to the center, the design of the fastening structure can increase the fluidity of the injected plastic, thereby shortening the holding time and facilitating the molding of the plastic frame on the metal backing plate. [Embodiment] In order to explain in detail the technical contents, structural features, objectives and effects of the present invention, the following is a detailed description with reference to the drawings. 6 M343174 Please refer to the first figure and the second figure, and the first embodiment of the frame of the backlight module which is not the present invention. In the case of the sound, the frame of the backlight module includes A metal back plate 1 and a plastic frame 2. The metal back plate 1 has a bottom plate ί1, and the peripheral edges of the bottom plate 11 respectively extend vertically upward with the side plates 12, and the side plates 12 are not connected to each other, so as to be spaced apart from each other between the adjacent side plates 12, and Each of the side plates 12 has two opposite first side edges 121 and a second side edge 122 that is pulled and two first side edges 121 are formed. One of the one side plates 12 is provided with a __κ solid structure in the middle of the first side 121. The fastening structure is formed by a bump 13 projecting from the middle of the side 121 of the side. The plastic frame 2 is molded on the metal back plate, and has a hinge wall 21 formed on the inner side of the side plate 12, and a joint formed between the adjacent side plates 12 respectively. 22 and a fastening portion corresponding to the fastening structure, the fastening portion is formed on the corresponding money. The groove 23 on the 卩22, the concave 栲μ is engaged with the projection 13. The plastic frame> The accommodating space enclosed by the backing plate 1 is for accommodating the optical component (not shown). The second two-part clearing is referred to the third drawing, and the casket is a second embodiment of the housing that is not the original backlight module. In the embodiment, the frame of the backlight module is the same as the frame structure of the first body of the backlight module, and the difference is that: in the embodiment, the structure is not fixed. a recessed opening 121 recessed by a lower end of a first side of the side panel 12, the latching portion being formed on a corresponding block 24 of the connecting portion M343174, the latching block 24 being fitted into the recessed opening Referring to the fourth figure, the third embodiment of the frame of the backlight module is shown. In this embodiment, the backlight module is The body is substantially the same as the frame structure of the backlight module in the first embodiment, and the difference is that: in the embodiment, the middle side of the second side 122 of the side plate 12 of the metal back plate 1 is provided with a card. The solid structure is a recess 15 recessed by the second side _122 of the one side panel 12; the fastening portion is a general block 25 formed on the corresponding frame wall 21, the insert 25 In the above, the fastening structure of the metal back plate 1 of the frame of the backlight module of the present invention is disposed on one side of one side plate 12, so that when the plastic frame 2 is injection molded In the direction of injection plastic, whether from top to bottom, from bottom to top or from side to center, the design of the fastening structure can increase the fluidity of the injected plastic, thereby shortening the dwell time and facilitating the plastic frame 2 Molded on metal back
