Abstract

The invention provides a display shell which can comprise a first shell and a second shell. The first shell is provided with a first inner surface, and a first connecting structure is arranged on the first inner surface. The first connecting structure is provided with a first connecting unit and a spring sheet. The first connecting unit is fixed on the first inner surface, and the elastic sheet is arranged on the first inner surface through the first connecting unit. The material yield strength of the elastic sheet is greater than that of the first shell. The second shell is provided with a second inner face. The second inner surface faces the first inner surface and is provided with a second connecting structure. The second connecting structure is detachably clamped with the elastic sheet. Because the material yield strength of the elastic sheet is greater than that of the first shell, the display shell can be thinner than a traditional clamping hook structure made of the same material as the shell under the condition of being capable of bearing the specification requirements of assembling and disassembling for the same times.

Description

Display casing

Technical Field

The present invention relates to a display housing, and more particularly, to a thin display housing.

Background

The thin design not only can make the electronic product have more space efficiency and more beautiful, but also is easier to carry/carry. In addition to the process of electronic circuits, the process of electronic devices in various aspects also has a great influence on the production process of displays and the thinning of finished products.

Referring to fig. 2, in some embodiments of the present invention, the display housing 100 may include a first housing 1000 and a second housing 2000. As shown in fig. 2, the first casing 1000 has a first inner surface 1100, and one or more first connection structures 1200 may be disposed on the first inner surface 1100. In these embodiments, the first inner surface 1100 is a surface of the first casing 1000 facing the second casing 2000, and can be clamped together with the second casing 2000 to form an accommodating space for accommodating other modules. In a preferred embodiment, the first connecting structure 1200 may be disposed on the first inner surface 1100 closer to an edge of the first casing 1000, for example, closer to the sidewall 1300 of the first casing 1000. In these embodiments, the first housing 1000 and the second housing 2000 are made of, for example, a plastic material, but not limited thereto.

As shown in fig. 2, in some embodiments, the first connection structure 1200 may have a first connection unit 1211 and a resilient piece 1220. Fig. 3 is a schematic top view of the elastic piece 1220 in fig. 2, referring to fig. 3, in some embodiments, the elastic piece 1220 has a first connecting section 1241, a second connecting section 1242 and a fastening portion 1260, the first connecting section 1241 and the second connecting section 1242 are attached to the side wall 1300, and the fastening portion 1260 abuts against the side wall 1300 at a bottom thereof.

As shown in fig. 2, in some embodiments, the first connection unit 1211 is formed in a protruding point or a protruding column shape, and the first connection unit 1211 is disposed on the first inner surface 1100 in advance before being combined with the resilient piece 1220. The first connecting unit 1211 is made of, for example, a hot melt material that is injection molded together with the first casing 1000, and the melting point of the first connecting unit 1211 is preferably lower than the melting point of the first casing. In these embodiments, during the assembly process, the first connection unit 1211 may be thermally melted to adhere the elastic piece 1220 to the first inner surface 1100, in other words, the elastic piece 1220 may be disposed on the first inner surface 1100 through the first connection unit 1211.

For example, in other embodiments, the first connection unit may be a micro screw or a micro rivet.

It should be noted that in fig. 2, the first connecting structure 1200 also has a second connecting unit 1212, and both of them correspond to the same elastic piece 1220. However, the present invention is only illustrative of some embodiments of the present invention, and the present invention is not limited thereto. For example, in other embodiments, the first connection structure 1200 may have any number of connection units according to requirements, for example, only a single first connection structure 1200 corresponds to a single spring piece 1220. 1220 has a material yield strength (or yield strength) greater than that of first shell 1000. For example, in one embodiment, the spring 1220 may be a metal spring; in another embodiment, the spring 1220 may be a carbon fiber spring; in another embodiment, the resilient piece 1220 may be a Fiberglass reinforced plastic (Fiberglass reinforced plastics) resilient piece. Therefore, the thickness of the resilient tab 1220 can be thinner or smaller than the conventional hook structure made of the same material as the housing, and can withstand repeated assembly and disassembly.

Referring to fig. 2, in some embodiments, the second housing 2000 has a second inner face 2100. The first housing 1000 and the second housing 2000 can be assembled together with the second inner surface 2100 facing the first inner surface 1100, for example, the first housing 1000 and the second housing 2000 can be pressed together, and the second connection structure 2220 and the first connection structure 1200 can be engaged along the trajectory TR, so that the first housing 1000 and the second housing 2000 can be assembled together. The second connecting structures 2210-2220 are disposed on the second inner surface 2100, and in some embodiments, the second connecting structures 2210-2220 may be hooks extending toward the edge of the second housing 2000. As shown in FIG. 2, the second connecting structures 2220 have a thicker thickness near the center of the second inner surface 2100 and a thinner thickness near the edge of the second housing 2000, and the thickness of the second connecting structures 2210 is the same. The second connecting structures 2210-2220 may be disposed on the second inner surface 2100 closer to the edge of the second housing 2000. In the assembling process of the display, the second connecting structure 2210 and the spring plate 1220 can be fastened to assemble the display housing of the present invention, or the fastened second connecting structure 2210 and the spring plate 1220 can be separated to disassemble the display housing of the present invention. Although fig. 2 shows that two second connection structures 2210-2220 are disposed on the second inner surface 2100, this is only schematically illustrated, and in other embodiments, the number of the first connection structures 1200 provided on the first housing 1000 is determined.

Referring to fig. 3, in some embodiments, the resilient tabs 1220 form openings 1230 into the first inner face 1100. In detail, the first connecting section 1241 may have a first arm 1231 and a second arm 1232, and the first arm 1231 and the second arm 1232 protrude from the engaging portion 1260 in a direction transverse to the extending direction of the resilient tab 1220 and jointly define the opening 1230; in addition, the free ends of the first and

second arms

1231, 1232 are not connected to form a gap therebetween that is smaller than the diameter of the opening 1230. As shown in fig. 2, in the embodiments, the thermally fused first connecting units 1213 are in the form of the thermally fused first connecting units 1211-1212, and the thermally fused first connecting units 1213 pass through the opening 1230 and interfere with a surface of the elastic piece 1220 opposite to the first inner surface 1100, so as to adhere the elastic piece 1220 to the first inner surface 1100. In the embodiment of FIG. 2, in which the first connecting units 1211-1212 are a hot-melt material fixed on the first inner surface 1100, the openings 1230 allow the first connecting units 1211-1212 to protrude from the elastic pieces 1220, so that the first connecting units 1211 can be more easily hot-melted. Fig. 3 is a top view of the elastic sheet, and as shown in fig. 3, in a preferred embodiment, the inner edge of the opening 1230 has a slant surface 1233. Fig. 4 is a cross-sectional view of the elastic sheet of fig. 2 along line a-a', as shown in fig. 4, the inclined surface 1233 gradually approaches the center of the opening 1230 from top to bottom, so that the thermally fused first connecting unit 1213 is a cone with a wide top and a narrow bottom. Compared to the opening without the inclined surface, the opening 1230 with the inclined surface 1233 can make the elastic sheet 1220 more firmly adhered to the first inner surface 1100 because the heat-melted first connecting unit 1213 is tapered. It should be noted that, depending on the heat-melting operation, the heat-melted first connecting unit 1213 may interfere with only the first arm 1241 or the second arm 1242.

The foregoing description is by way of example only and is not intended as limiting. For example, in some other embodiments, the elastic sheet 1220 may not have an opening, and the worker may first heat-melt the first connection unit 1211 and then place the elastic sheet 1220 without an opening on the heat-melted first connection unit 1211 to adhere the elastic sheet 1220 to the first inner surface 1100. It should be noted that, in fig. 2 and fig. 3, the elastic piece 1220 has two openings, which is only a schematic illustration of some embodiments of the present invention, and the present invention is not limited thereto. For example, in other embodiments, the spring plate 1220 may have no openings or any number of openings, as desired.

As shown in fig. 3, the engaging portion 1260 is located between the first connecting section 1241 and the second connecting section 1242. Referring to fig. 2 and 3, in some embodiments, the engaging portion 1260 forms an arch structure relative to the first connecting section 1241 and the second connecting section 1242 away from the first inner surface 1100 (as shown in fig. 6, the engaging portion is away from the first inner surface 1100 by a distance h). However, this is merely an illustration and the present invention is not limited thereto, and in other embodiments, the engaging portion 1260 may comprise a thin sheet parallel to the first inner surface 1100 and have any shape. For example, the resilient tab 1220 may only include a single first connecting segment 1241 without a second connecting segment 1242, so that the engaging portion 1260 extends from the first connecting segment 1241 to form a cantilever structure.

Fig. 5 is a cross-sectional view of the display housing formed by assembling the first housing and the second housing shown in fig. 2, referring to fig. 5, after the first housing 1000 and the second housing 2000 are assembled, since the bottom of the engaging portion 1260 is close to the side wall 1300, after the first housing is assembled with the second housing, the engaging portion 1260 is relatively close to the side wall 2400 of the second housing 2000, and therefore, the side wall 2400 can prevent the engaging portion 1260 from sliding in the direction SD, thereby increasing the structural stability after the first housing 1000 and the second housing 2000 are assembled.

Referring to fig. 2, in some embodiments, a positioning unit 1291 is disposed on the first inner face 1100. As shown in fig. 2, the elastic sheet 1220 abuts against the positioning unit 1291 to position the elastic sheet 1220 on the first casing 1000. In this way, during the assembly process, before the worker fuses the first connection unit 1211 or the second connection unit 1212 to adhere the elastic piece 1220 to the first inner surface 1100, the worker can press the elastic piece 1220 against the positioning unit 1291 to perform the fusing operation more conveniently.

It should be noted that the above is only for illustration and not for limiting the invention, for example, in other embodiments, the first housing 1000 may not have the positioning unit 1291. Fig. 2 is merely illustrative, and in other embodiments, the first connection structure does not necessarily have the same number of positioning units as that shown in fig. 2.

Referring to fig. 2 and 3, the positioning unit 1291 is not shown in fig. 3 for clarity of the second recess 1280. As shown in fig. 3, in some embodiments, the resilient plate 1220 has a second concave portion 1280, and the second concave portion 1280 has a first side edge 1281 and a second side edge 1282, as shown in fig. 2 and 3, the first side edge 1281 and the second side edge 1282 can respectively abut against different portions of the positioning unit 1291 to position the resilient plate 1220, so as to facilitate assembly (as described above). It should be noted that the foregoing is illustrative only and is not limiting.

Fig. 6 is a schematic diagram of the display housing 200 according to some embodiments of the invention, and referring to fig. 6, in these embodiments, the second housing 2000 may include a limiting unit 2300 extending along an edge parallel to the second housing 2000. For example, as shown in fig. 6, the stopper units 2300 may be a plurality of ribs extending along an edge parallel to the second housing 2000, respectively. Fig. 7 is a schematic top view of the spring piece 1220 in fig. 6, and referring to fig. 7, the engaging portion 1260 is retracted relative to the first connecting section 1241 and the second connecting section 1242 by a distance d in a direction intersecting the extending direction ED of the spring piece 1220 to form a first recess 1270. As shown in fig. 6, in these embodiments, the extending direction ED may be a direction parallel to the edge of the first housing 1000. In other words, the first connecting section 1241 and the second connecting section 1242 have a larger width in the extending direction ED of the transverse spring 1220 than the engaging portion 1260, so as to facilitate connection with the first connecting unit 1211 and the second connecting unit 1212.

Fig. 8 is a cross-sectional view of the first housing 1000 and the second housing 2000 assembled together in some embodiments shown in fig. 6. as shown in fig. 8, when the first housing 1000 and the second housing 2000 are assembled, the position limiting unit 2300 blocks the engaging portion 1260 on the side of the first recess 1270 (i.e., the side of the elastic piece 1220 close to the edge of the first housing) to prevent the engaging portion 1260 from sliding in the direction SD, thereby increasing the structural stability of the assembled first housing 1000 and the second housing 2000. It should be noted that the number of the limiting units 2300 illustrated in fig. 6 is only an example, and in other embodiments, the number of the limiting units 2300 is determined according to the number of the first connecting structures 1200 of the first housing 1000.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such alterations and modifications are included in the invention, insofar as they do not depart from the spirit and scope of the invention.
