Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the touch display device 1 of the present invention includes a frame 10 , a display module 20 fixed in the frame 10 and a touch panel 30 fixed on the frame 10 . The frame 10 is composed of an outer shell 11 , an inner frame 12 and a cover frame 13 .

The housing 11 has a base plate 110 in the shape of a rectangular plate, and sidewalls 111 are bent vertically upwards from the periphery of the base plate 110 . A plurality of locking slots 112 are defined on the side wall 111 , and a plurality of locking blocks 113 are protrudingly provided. A housing opening 114 is formed on one side wall 111 .

The inner frame 12 is made of plastic material, and it is arranged in the outer shell 11. The inner frame 12 has several frames 120, and the several frames 120 enclose a first square space 121, and the outer edge of each frame 120 is vertical. A frame wall 122 extends upward, and one of the frame walls 122 defines an inner frame opening 125 corresponding to the shell opening 114 . The frame wall 122 is protruded with a plurality of projections 123 that engage with the slots 112 of the housing 11, and two adjacent frame walls 122 are respectively protruded with at least one tenon 124 perpendicular to the frame 120, and the The height of the tenon 124 is not greater than the thickness of the touch panel 30 .

The cover frame 13 covers the shell 11 and has a frame edge 130 which encloses a second square space 131 . The outer side of the frame edge 130 is bent vertically downwards to extend a side wall 132 . The frame edge 130 defines an opening 133 through which the tenon 124 of the inner frame 12 passes. The sidewall 132 defines a plurality of slots 134 engaging with the blocks 113 of the casing 11 , and defines a cover frame opening 135 corresponding to the casing opening 114 .

Please refer to FIG. 2 and FIG. 3 in conjunction with FIG. 1. The side wall 111 of the outer shell 11 covers the frame wall 122 of the inner frame 12, and is fastened and combined with the protrusion 123 by the slot 112; the side wall 132 of the cover frame 13 covers the outer shell. The side wall 111 of 11 is fixed together with the slot 134 and the clamping block 113, so that the outer shell 11, the inner frame 12 and the cover frame 13 enclose an inner space (not shown in the figure). The display module 20 is placed in the inner space of the frame 10 . The touch panel 30 is glued and fixed on the frame edge 130 of the cover frame 13 . When bonding the touch panel 30, since the end of the tenon 124 passes through the opening 133 of the cover frame 13 and is located above the frame edge 130, the side of the touch panel 30 can be positioned against the tenon 124 for positioning. .
