Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted display screens, in particular to a plastic middle frame. Background Technique

[0002] Nowadays, more and more automotive display modules are assembled and installed on vehicles by laminating a touch display module with a casting. The casting can provide higher strength. Generally, aluminum-magnesium alloy is selected for the casting to improve the strength of the product. In some projects, in order to save costs, plastic is used for injection molding to replace the alloy to save costs. The traditional casting assembly process generally uses RTV glue for dispensing and then laminating and pressure maintaining.

[0003] However, due to the poor flatness of the plastic middle frame, when using the plastic middle frame, if the flatness is too poor, there will be a stress pull on the display module by the plastic middle frame during lamination with the display module, and problems such as uneven display are likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a plastic middle frame.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0008] In one embodiment, the dispensing path extends downward from the upper surface of the middle frame body by 0.5 mm - 1 mm.

[0023] In order to facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0024] A plastic middle frame, referring to Figure 1 , includes a middle frame body 10. The middle frame body 10 is used to fit with a display module and be assembled to a vehicle-mounted computer. The middle frame body 10 is a plastic part and is formed by injection molding of plastic materials.

[0025] Referring to Figure 1, when the middle frame body 10 is attached to the display module, it is attached and pressure-maintained after dispensing glue, so as to fixedly attach the display module to the middle frame body 10.

[0026] Refer to Figure 1 , a dispensing path 20 is provided on the middle frame body 10. The dispensing path 20 is formed on the upper surface of the middle frame body 10, and the dispensing path 20 is located on one side of the middle frame body 10 facing the display module. The dispensing path 20 is arranged along the circumferential direction of the middle frame body 10, and the dispensing path 20 surrounds the middle frame body 10 for one circle, so that the four sides of the display module are fixedly attached to the middle frame body 10.

[0027] Refer to Figure 1 , the dispensing path 20 is recessed from the upper surface of the middle frame body 10 into the middle frame body 10. The dispensing path 20 is integrally formed during the injection molding of the middle frame body 10. The dispensing path 20 is filled with glue, and the display module is attached to the middle frame body 10 by injecting RTV glue into the dispensing path 20.

[0028] Refer to Figure 1 , since the middle frame body 10 is a plastic part and its hardness is not strong resulting in poor flatness, there will be a stress pull on the display module when the middle frame body 10 is attached to the display module, and problems such as uneven display are likely to occur. Therefore, the dispensing path 20 in this embodiment is set to be sunken. The dispensing path 20 extends a certain distance into the middle frame body 10 to increase the thickness of the glue to absorb the stress caused by the deformation of the middle frame body 10.

[0029] Furthermore, refer to Figure 1 , the dispensing path 20 extends downward from the upper surface of the middle frame body 10 by 0.5 mm - 1 mm. By deepening the depth of the dispensing path 20 to increase the thickness of the glue, the increased glue thickness can allow the glue to better absorb the stress caused by the deformation of the middle frame body 10, thereby reducing the pulling stress on the display module due to the poor flatness of the middle frame body 10, and thus reducing the occurrence of uneven display.

[0030] In one embodiment, refer to Figure 1 , in order to improve the hardness of the middle frame body 10, the plastic material for making the middle frame body 10 includes graphene for enhancing strength. Adding graphene to the plastic material can enhance the strength of the middle frame body 10, so that the middle frame body 10 is not easily deformed.

[0031] Furthermore, refer to Figure 2 , in order to improve the performance of the middle frame body 10, a UV primer layer 30 is provided on the middle frame body 10. The UV primer layer 30 is sprayed on the outer surface of the middle frame body 10 and is formed by UV light irradiation. The UV primer layer 30 includes polyurethane acrylate resin, and the UV primer layer 30 is used to improve the flexibility of the middle frame body 10, so that the middle frame body 10 is not easily broken.

[0032] Further, referring to Figure 2 , the thickness of the UV primer layer 30 is 10 μm - 15 μm.

[0033] Referring to Figure 2 , a coating layer 40 is provided above the UV primer layer 30, and the coating layer 40 is sputtered on the surface of the UV primer layer 30.

[0034] Further, referring to Figure 2 , the thickness of the coating layer 40 is 2 μm - 5 μm.

[0035] Referring to Figure 2 , a UV topcoat layer 50 is provided above the coating layer 40. The UV topcoat layer 50 is used to protect the coating layer 40, and the UV topcoat layer 50 is used to increase the hardness of the middle frame body 10 so as to improve the flatness of the middle frame body 10.

[0036] Further, referring to Figure 2 , the thickness of the UV topcoat layer 50 is 15 μm - 30 μm.

[0037] Referring to Figure 2 , the cooperation of the UV primer layer 30, the coating layer 40 and the UV topcoat layer 50 further improves the performance of the middle frame body 10, enhances the strength of the middle frame body 10, and makes the middle frame body 10 not easily break.

[0038] The plastic middle frame increases the thickness of the glue by deepening the glue application path 20. The increased glue thickness can allow the glue to better absorb the stress caused by the deformation of the middle frame body 10, thereby reducing the pulling stress on the display module due to the poor flatness of the middle frame body 10, and thus reducing the occurrence of uneven display.

[0039] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
