Because the plastic part 20 and the housing body 10 form an integral structure through injection molding, a gap generated by the clamping and matching of the housing body 10 and the plastic part 20 is avoided, and thus, the problem of light leakage in the rear view is solved. On the basis, since the material of the silicone part 30 includes silicone, the size of the silicone part 30 can be designed to be slightly larger when the silicone part 30 is designed, so that proper elasticity of the silicone facilitates the assembly of the light guide plate 021 in place, and the light guide plate 021 is ensured to have no moving space; on the other hand, the expansion and compression amount of the light guide plate 021 under different environments can be satisfied to ensure zero gap between the light guide plate 021 and the silicone part 30, so that when the housing 01 is applied to a liquid crystal display device, the stability of the display image and the optical quality of the liquid crystal display panel 03 is ensured.

In the case that the plastic part 20 and the housing body 10 are integrally formed by injection molding, and the silicone part 30 and the plastic part 20 are integrally formed by injection molding, in some embodiments, as shown in fig. 6, the process of manufacturing the housing 01 is as follows: firstly, stamping the shell main body 10 by using a die; then, the housing main body 10 is placed into an injection mold for injection molding to form a plastic part 20; then, putting the semi-finished product of the shell into a silica gel injection mould for injection to form a silica gel part 30; the housing 01 is molded.

In the embodiment of the present invention, the silicone part 30 and the plastic part 20 form an integral structure by injection molding, on one hand, when the housing 01 is formed, the silicone part 30 and the plastic part 20 do not need to be assembled together, so that the assembling process of the housing 01 can be saved, the manufacturing process of the housing 01 can be simplified, the labor can be reduced, and the manufacturing efficiency of the housing 01 can be improved; on the other hand, the silicone part 30 is firmly combined with the plastic part 20, and after the backlight assembly 02 and the housing 01 are assembled, instability of the display image and the optics of the liquid crystal display panel caused by unfixed light guide plate 021 is avoided.

Optionally, as shown in fig. 8, the plastic part 20 includes a first engaging portion 201, and the silicone part 30 includes a second engaging portion 301; the first engaging portion 201 and the second engaging portion 301 are engaged with each other.

Here, the first engaging portion 201 and the second engaging portion 301 are not limited to the above, and the first engaging portion 201 and the second engaging portion 301 can be engaged and connected. In some embodiments, the first engaging portion 201 is a groove, and the second engaging portion 301 is a protrusion. In other embodiments, the first engaging portion 201 is a protrusion, and the second engaging portion 301 is a groove. Fig. 8 illustrates an example in which the first engaging portion 201 is a groove and the second engaging portion 301 is a protrusion.

The embodiment of the utility model provides a, because plastic part 20 includes first block portion 201, silica gel part 30 includes second block portion 301, and first block portion 201 and second block portion 301 block are connected, thereby are favorable to increasing the area of contact of plastic part 20 and silica gel part 30, and then are favorable to plastic part 20 and silica gel part 30 closely to be fixed together.

Alternatively, as shown in fig. 9, the plastic part 20 further extends from the outer side surface of the sidewall to the surface of the sidewall far from the bottom surface, i.e. the upper surface of the sidewall in fig. 9.

The embodiment of the present invention provides a case 01 when being applied to a liquid crystal display device, when the liquid crystal display panel 03 is located above the case 01, the liquid crystal display panel 03 is fixed with the case 01 through an adhesive tape 031, considering that if the plastic part 20 only passes through the through hole 101, the direction far away from the bottom surface extends to the lateral surface of the lateral wall, and the lateral wall does not extend to the surface far away from the bottom surface, when the adhesive tape 031 is pasted with the case 01, because the thickness of the lateral wall of the case main body 10 is smaller, in order to ensure the contact area between the adhesive tape 031 and the case 01, so as to ensure that the adhesive tape 031 is firmly fixed with the case 01, as shown in fig. 10, the adhesive tape 031 partially contacts with the case main body 10, and partially contacts. However, since the material of the housing main body 10 is different from the material of the plastic member 20, when the tape 031 contacts the housing main body 10 and the plastic member 20, the force applied to the tape 031 is not uniform, and the tape 031 is easily separated from the housing 01, so that the liquid crystal display panel 03 and the housing 01 cannot be effectively fixed together.

Based on the above, when the plastic part 20 further extends from the outer side surface of the sidewall to the surface of the sidewall away from the bottom surface, when the tape 031 is adhered to the housing 01, the tape 031 is entirely in contact with the plastic part 20, so that the force applied to the tape 031 is uniform, and thus, the tape 031 is not easily separated from the housing 01, and the liquid crystal display panel 03 and the housing 01 can be effectively fixed together.

Alternatively, as shown in fig. 11, a portion of the sidewall located away from the bottom surface of the through hole 101 is closer to the center of the bottom surface than other portions of the sidewall located away from the bottom surface of the through hole 101; the portion of the sidewall located away from the bottom surface of the through-hole 101 is the same thickness as the other portion of the sidewall, i.e., the thickness of the sidewall is the same everywhere.

Here, a portion of the side wall located away from the bottom surface of the through hole 101 is recessed toward the inside of the case 01 with respect to the other portion of the side wall located away from the bottom surface of the through hole 101, that is, the portion of the side wall located away from the bottom surface of the through hole 101.

In the embodiment of the present invention, because the portion of the sidewall of the housing main body 10 located at the through hole 101 and far away from the bottom surface is close to the center of the bottom surface for the other portion of the sidewall except the portion of the sidewall located at the through hole 101 and far away from the bottom surface, and the thickness of the sidewall is the same everywhere, therefore, the lateral surface of the portion of the sidewall located at the through hole 101 and far away from the bottom surface and the lateral surface of the portion of the sidewall located at the through hole 101 and near the bottom surface are not in the same plane, and thus, when the plastic part 20 is formed integrally with the housing main body 10 through injection molding, the contact area between the plastic part 20 and the housing main body 10 can be increased.

On the basis, since the plastic member 20 is disposed on the outer side surface of the portion of the sidewall located away from the bottom surface of the through hole 101, if, as shown in fig. 10, the inner side surface (or the outer side surface) of the portion of the sidewall located away from the bottom surface of the through hole 101 and the inner side surface (or the outer side surface) of the portion of the sidewall located close to the bottom surface of the through hole 101 are in the same plane, the outer surface of the housing 01 is not flat, and there is a step T as shown in fig. 10. And since the portion of the side wall of the case main body 10 located at the portion of the through hole 101 distant from the bottom surface is close to the center of the bottom surface with respect to the other portion of the side wall except for the portion of the through hole 101 distant from the bottom surface, the step T can be reduced or eliminated.

The distance L (as shown in fig. 11) between the inner surface (or outer surface) of the side wall located at the portion of the through hole 101 away from the bottom surface and the inner surface (or outer surface) of the side wall located at the portion of the through hole 101 close to the bottom surface is not limited and may be set as needed. If the distance L between the inner side surface of the portion of the sidewall located at the position where the through hole 101 is far from the bottom surface and the inner side surface of the portion of the sidewall located at the position where the through hole 101 is near the bottom surface is small, on one hand, the difficulty in manufacturing the housing body 10 is increased, and on the other hand, the contact area between the plastic part 20 and the housing body 10 cannot be increased significantly. If the distance L between the inner side surface of the portion of the side wall located at a position where the through hole 101 is far from the bottom surface and the inner side surface of the portion of the side wall located at a position where the through hole 101 is near the bottom surface is large, the portion of the side wall located at a position where the through hole 101 is far from the bottom surface and the portion of the side wall located at a position where the through hole 101 is near the bottom surface may be broken when the case main body 10. Thus, when the housing 01 is applied to a liquid crystal display device, there is a possibility that light leakage occurs in a rear view.

Based on the above, in some embodiments, the distance L between the inner side surface of the portion of the side wall located far away from the bottom surface of the through hole 101 and the inner side surface of the portion of the side wall located near the bottom surface of the through hole 101 is 1/3-1/2 of the thickness H of the side wall.

Here, the distance L between the inner side surface of the portion of the side wall located away from the bottom surface of the through hole 101 and the inner side surface of the portion of the side wall located close to the bottom surface of the through hole 101 may be 1/3, 1/2.5, 1/2, or the like of the side wall thickness H.

The embodiment of the utility model provides an in, because lie in the lateral wall in the through-hole 101 keep away from the medial surface of the part of bottom surface and lie in the lateral wall in the through-hole 101 and be close to the distance L between the medial surface of the part of bottom surface for 1/3 ~ 1/2 of lateral wall thickness H, therefore both can effectively increase the area of contact of shell main part 10 and plastic part 20, ensure that shell main part 10 and plastic part 20 firmly link together, can avoid again to lie in the lateral wall in the part that bottom surface was kept away from to through-hole 101 and the part fracture that bottom surface is close to lie in through-.

Alternatively, as shown in fig. 11, the outer side surface of the portion of the sidewall near the bottom surface of the through hole 101 and the surface of the plastic part 20 far from the outer side surface of the sidewall are located in the same plane.

Because the outer side surface of the part of the side wall, which is positioned at the through hole 101 and close to the bottom surface, and the surface of the plastic part 20, which is far away from the outer side surface of the side wall, are positioned in the same plane, the outer side surface of the shell 01 is flat, so that the volume of the shell 01 can be reduced on one hand, and the aesthetic degree of the shell 01 can be increased on the other hand.

A specific example is provided below to illustrate the manufacturing process of the housing 01 in detail.

First, as shown in fig. 12 and 13, the case main body blank is subjected to edge groove punching on a die, and the inner groove is subjected to inner groove punching to form a through hole 101 in the side wall, thereby finally forming the case main body 10. The number of stamped grooves can be adjusted as desired. The groove punching is to allow the plastic part 20 to be well joined to the housing main body 10. Cleaning the surface of the molded shell main body 10, removing edge burrs, and then putting the shell main body into a mold cavity of an injection mold; as shown in fig. 14 and 11, the plastic part 20 is injection molded by an injection molding machine and then removed. After injection molding, the plastic part 20 is combined with the groove and the through hole 101 of the housing body 10, so that the combination surface of the plastic part 20 and the housing body 10 is not easy to separate. Here, as shown in fig. 14 and 11, a groove (i.e., the first engaging portion 201) may be formed at a position of the plastic part 20 corresponding to the film material limiting and fixing position, the film material limiting and fixing position may be adjusted as required, and the length of the groove may be adjusted as required. Note that, the plastic member 20 may be formed at a part of the through hole 101. Cleaning the surface of the plastic part 20 after the injection molding of the plastic part 20 is finished, removing burrs at the edge, and flattening the main material port; the cleaned plastic part 20 is coated with glue at the position where the silica gel is needed to be injected and is placed into a mold cavity formed by an upper mold and a lower mold of a silica gel injection mold; after the mold is closed, the silicone rubber is injected under heat and pressure to form the silicone rubber member 30 shown in fig. 15 and 16. The silica gel part 30 is made of a silica gel mixture including: silica gel, vulcanizing agent, pigment, etc. The color, hardness and thickness dimensions of the silicone member 30 can be adjusted as desired. The silica gel injection position corresponds to the membrane material limiting position, and the length size is consistent with the membrane material limiting size.

Based on the above, after the housing 01 is manufactured, the backlight assembly 02 is assembled in the housing 01, and the liquid crystal display panel 03 is assembled, thereby manufacturing the liquid crystal display device. Assembling the backlight assembly 02 in the case 01 includes: a reflection sheet 023, a light guide plate 021 and an optical film 022 are sequentially assembled in the housing 01.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
