Abstract
Description
Technical Field
[0001] The present application relates to the field of screen pressing, and particularly to a screen pressing structure and an electronic device. Background Art
[0002] The screen pressing structure is a key component of a folding screen device. The screen pressing structure is located at the upper and lower ends of the bending area of the inner screen of the folding screen device and is assembled on the rotating shaft by means of glue; the screen pressing structure is generally set in a T shape, and the protruding part hangs above the screen and has a certain gap with the screen. The main functions of the screen pressing structure are to prevent the end of the inner screen bending area from being extruded by external forces, for decoration, and to block foreign objects.
[0003] However, during use, especially after multiple foldings, the colloid provided on the screen pressing structure is likely to fall off, resulting in the screen pressing structure losing its function. Utility Model Content
[0004] The purpose of the present application is to provide a screen pressing structure and an electronic device.
[0005] According to the first aspect of the embodiments of the present application, a screen pressing structure is provided. The screen pressing structure is applied to an electronic device with a folding screen, and the screen pressing structure includes:
[0006] A bracket part, the bracket part includes a bracket body and a boss connected to each other. The bracket body is arranged at the folding part of the folding screen. The boss includes a first surface, and the first surface faces the front of the folding screen. A fixing groove is provided on the bracket part, and at least part of the fixing groove is arranged on the first surface of the boss;
[0007] A diaphragm part, the diaphragm part is arranged on the first surface;
[0008] A colloid part, a part of the structure of the colloid part is connected to the diaphragm part, and another part enters the fixing groove to fix the bracket part and the diaphragm part;
[0009] Wherein, the cross-sectional area of at least part of the fixing groove is arranged to decrease in the direction from the boss to the diaphragm part.
[0010] It should be noted that in this embodiment, the cross-sectional area of at least part of the fixing groove is arranged to decrease in the direction from the boss to the diaphragm part, not only in the shape of an inverted cone or a chamfer, but also the fixing groove can be set in a stepped shape. The present application does not limit the fixing manner of the bracket part and the diaphragm part. For example, the diaphragm part is provided with an opening, and the colloid part enters the fixing groove through the opening to fix the bracket part and the diaphragm part; or, the diaphragm part can also be directly adhered to the bracket part by the viscosity of the colloid part.
[0011] Taking the diaphragm part as an example with an opening provided, the manufacturing process of the screen pressing structure is as follows: First, the bracket part and the diaphragm part are positioned and fixed through back glue. Then, the whole of the bracket part and the diaphragm part is placed into a mold. Through the injection molding method, the colloid part passes through the opening of the diaphragm part and is poured into the fixing groove of the bracket part. After the colloid part is cured, the diaphragm part can be fixed on the bracket part.
[0012] Based on the above settings, the fixing groove is in the shape of an inverted cone or chamfer. When the colloid part disengages from the fixing groove, at this time, the fixing groove close to the diaphragm part provides an oblique supporting force, thereby increasing the difficulty of the colloid part disengaging. Furthermore, the stability of the screen pressing structure is ensured, preventing the screen pressing structure from losing its function.
[0013] In some embodiments, the diaphragm part is provided with a film hole communicating with the fixing groove. A part of the colloid part is located on the side of the diaphragm part away from the first surface, and another part passes through the film hole and enters the fixing groove.
[0014] A part of the colloid part is located in the fixing groove, and another part passes through the film hole and is fixed on the surface of the diaphragm part facing away from the fixing groove, thereby realizing the overall fixing of the diaphragm part.
[0015] In some embodiments, the colloid part located on the surface of the diaphragm part close to the folding screen is a contact glue, and the thickness of the contact glue is greater than or equal to 0.1 mm and less than or equal to 0.4 mm.
[0016] Within the above thickness range, the contact glue can fix the diaphragm part well, so that the diaphragm part will not be easily pulled off by external force due to the contact glue being too thin.
[0017] In some embodiments, the orthographic projection of the film hole on the boss is located inside the fixing groove; and / or,
[0018] The ratio of the maximum cross-sectional area of the film hole to the minimum cross-sectional area of the fixing groove is greater than or equal to 1:10 and less than or equal to 9:10.
[0019] The orthographic projection of the film hole on the boss being located inside the fixing groove can facilitate pouring the colloid part into the fixing groove of the bracket part during injection molding. Within the above ratio range, on the one hand, it can facilitate the injection of the colloid part from the film hole into the fixing groove, and on the other hand, it can also fix the bracket part and the diaphragm part well.
[0020] In some embodiments, the hardness of the colloid part is greater than or equal to 40 degrees and less than or equal to 60 degrees.
[0021] Within this hardness range, even if the folding screen comes into contact with the colloid part, the folding screen will not be directly damaged. Especially when the electronic device is folded for the first time, the folding screen located below the colloid part may bulge, which may cause the folding screen to come into contact with the colloid part. In this embodiment, the colloid part selected within this hardness range can be compressed when the folding screen comes into contact with the colloid part, thereby protecting the folding screen.
[0022] In some embodiments, the colloid part is made of silica gel and / or rubber. Silica gel and rubber can well achieve the above hardness range, and the folding screen will not be easily damaged when in contact.
[0023] In some embodiments, the fixing groove includes a first groove body and a second groove body that communicate with each other, and the first groove body is disposed on a side of the bracket body close to the folding screen, and the second groove body is disposed on the first surface of the boss;
[0024] The first groove body and / or the second groove body is / are arranged to decrease from the surface close to the diaphragm part to the surface away from the diaphragm part, and the colloid part covers the first groove body and the second groove body.
[0025] Since the first groove body and the second groove body are connected and communicate with each other, the colloid part can completely cover the diaphragm part on one side of the membrane hole, so that the fixing between the bracket part and the diaphragm part is more firm. In addition, since the first groove body or the second groove body is arranged to decrease from the surface close to the diaphragm part to the surface away from the diaphragm part, when the colloid part detaches from the first groove body or the second groove body, the edge of the first groove body or the second groove body provides a reverse thrust to prevent the colloid part from detaching.
[0026] In some embodiments, a through hole is further provided in the bracket body. One end of the through hole communicates with the first groove body. At least part of the structure of the colloid part is located in the through hole, and the cross section of the through hole is gradually increased from the first groove body in a direction away from the folding screen.
[0027] Based on the above settings, when the colloid part detaches from the first groove body, it will be blocked by the colloid part located in the through hole, so that the colloid part is more difficult to separate from the first groove body.
[0028] In some embodiments, the first groove body includes a first groove unit and a second groove unit that communicate with each other. The first groove unit communicates with the second groove body. A through hole is further provided in the bracket body. One end of the through hole communicates with the second groove unit. At least part of the colloid is located in the through hole; along the thickness direction of the bracket body, there is a non-overlapping part between the orthographic projections of the through hole and the second groove unit.
[0029] Based on the above settings, when the colloid part detaches from the first tank body, the non-overlapping part between the perforation and the orthographic projection of the second tank unit will provide a reverse blocking force, making it more difficult for the colloid part to separate from the first tank body, thereby enhancing the stability of the screen pressing structure.
[0030] According to a second aspect of the embodiments of the present application, there is provided an electronic device, including:
[0031] A folding screen;
[0032] A middle frame, the folding screen is connected to the middle frame, and the middle frame is provided with an avoidance groove facing the folding screen;
[0033] The screen pressing structure according to any one of the above embodiments, the screen pressing structure includes a bracket body and a convex platform connected to each other, and the avoidance groove is provided corresponding to the connection part between the bracket body and the convex platform.
[0034] When the electronic device falls from a height, especially when the electronic device falls from a height in a folded state, the middle frame is recessed inward, thereby pressing the screen pressing structure closer to the folding screen, and then damaging the folding screen. In the present application, by providing an avoidance groove on the middle frame and arranging the avoidance groove corresponding to the connection part between the bracket body and the convex platform, when the middle frame is recessed inward, due to the presence of the avoidance groove, the screen pressing structure can be prevented from approaching the folding screen, so that the folding screen will not be damaged, thereby achieving the effect of protecting the folding screen.

[0070] With the development of technology, folding screen mobile phones have become the choice of more and more people. At the same time, due to the nature of the folding screen 21 itself that needs to be folded, components such as hinges and screen pressing structures 10 need to be provided at its bending part. Among them, referring to Figure 1 As shown, the screen pressing structure 10 is located at the upper and lower ends of the bending area of the folding screen 21 of the electronic device 20 and is assembled on the hinge rotating shaft by means of glue; the screen pressing structure 10 is generally set in a T shape, and the protruding part hangs above the folding screen 21 and has a certain gap with the folding screen 21. The main function of the screen pressing structure 10 is to prevent the end part of the bending area of the folding screen 21 from being squeezed by external forces and to block foreign objects from entering the folding screen 21.
[0071] However, during use, especially after the folding screen 21 is folded multiple times, the colloid provided on the screen pressing structure 10 is likely to fall off, resulting in the screen pressing structure 10 losing its function.
[0072] The present application proposes a screen pressing structure 10. Referring to Figure 1 As shown, the screen pressing structure 10 is applied to an electronic device 20 having a folding screen 21. Referring to Figure 4 and Figure 5 As shown, the screen pressing structure 10 includes: a bracket part 100, a diaphragm part 200, and a colloid part 300. Referring to Figure 2 and Figure 3As shown, the bracket part 100 includes a bracket body 110 and a boss 120 that are connected to each other. The bracket body 110 is disposed at the folding position of the folding screen 21. The boss 120 includes a first surface 121, and the first surface 121 faces the front of the folding screen 21. Refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a fixing groove 130 is provided on the bracket part 100, and the fixing groove 130 is at least partially disposed on the first surface 121 of the boss 120; the diaphragm part 200 is disposed on the first surface 121; a part of the structure of the colloid part 300 is connected to the diaphragm part 200, and the other part enters the fixing groove 130 to fix the bracket part 100 and the diaphragm part 200; wherein, refer to Figure 9 As shown, the cross-sectional area of at least a part of the fixing groove 130 is set to decrease in the direction from the boss 120 to the diaphragm part 200.
[0073] It should be noted that the cross-sectional area of at least a part of the fixing groove 130 in this embodiment is set to decrease in the direction from the boss 120 to the diaphragm part 200, which not only includes Figure 9 As shown, the fixing groove 130 is in the shape of an inverted cone or a chamfer, and the fixing groove 130 can also be set in a stepped shape. The present application does not limit the fixing method of the bracket part 100 and the diaphragm part 200. For example, the diaphragm part 200 is provided with an opening, and the colloid part 300 enters the fixing groove 130 through the opening to fix the bracket part 100 and the diaphragm part 200; or, the diaphragm part 200 can also be directly adhered to the bracket part 100 through the viscosity of the colloid part 300.
[0074] Taking the example that the diaphragm part 200 is provided with an opening, the manufacturing process of the screen pressing structure 10 is as follows: First, the bracket part 100 and the diaphragm part 200 are fixed in position by back glue. Then, the whole of the bracket part 100 and the diaphragm part 200 is placed in a mold. Through the injection molding method, the colloid part 300 passes through the opening of the diaphragm part 200 and is poured into the fixing groove 130 of the bracket part 100. After the colloid part 300 is cured, the diaphragm part 200 can be fixed on the bracket part 100.
[0075] Based on the above settings, continue to refer to Figure 9 As shown, the fixing groove 130 is in the shape of an inverted cone or a chamfer. When the colloid part 300 comes out of the fixing groove 130, at this time, the fixing groove 130 close to the diaphragm part 200 provides an oblique supporting force, thereby increasing the difficulty of the colloid part 300 coming out. Furthermore, the stability of the screen pressing structure 10 is ensured, and the screen pressing structure 10 is prevented from losing its function.
[0076] In addition, the hardness of the colloid part 300 can be set to be greater than or equal to 40 degrees and less than or equal to 60 degrees. The material of the colloid part 300 can be made of silica gel or rubber, or can be jointly made of silica gel and rubber. For example, silica gel or rubber with hardnesses of 40 degrees, 45 degrees, 50 degrees, 55 degrees, and 60 degrees can be selected. Within this hardness range, even if the folding screen 21 touches the colloid part 300, the folding screen 21 will not be directly damaged. Especially when the electronic device 20 is folded for the first time, the folding screen 21 located below the colloid part 300 may bulge, thereby causing the folding screen 21 to come into contact with the colloid part 300. In this embodiment, the colloid part 300 within this hardness range is selected, so that when the folding screen 21 contacts the colloid part 300, the colloid part 300 compresses to protect the folding screen 21.
[0077] In this embodiment, referring to Figure 5 , Figure 6 , Figure 7 and Figure 8 as shown, the diaphragm part 200 is provided with a film hole 210 communicating with the fixing groove 130. A part of the colloid part 300 is located on the side of the diaphragm part 200 away from the first surface 121, and another part passes through the film hole 210 and enters the fixing groove 130.
[0078] Based on the above settings, referring to Figure 9 and Figure 12 as shown, a part of the colloid part 300 is located in the fixing groove 130, and another part passes through the film hole 210 and is fixed on the surface of the diaphragm part 200 facing away from the fixing groove 130, thereby realizing the overall fixation of the diaphragm part 200.
[0079] In this embodiment, referring to Figure 5 and Figure 9 as shown, the colloid part 300 located on the surface of the diaphragm part 200 close to the folding screen 21 is the contact glue 310. The thickness of the contact glue 310 is greater than or equal to 0.1 mm and less than or equal to 0.4 mm. Within the above thickness range, the contact glue 310 can well fix the diaphragm part 200, so that the diaphragm part 200 will not be easily pulled off by external force because the contact glue 310 is too thin. For example, the thickness of the contact glue 310 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm.
[0080] In this embodiment, referring to Figures 4 - 9 as shown, the positive projection of the film hole 210 on the boss 120 is arranged inside the fixing groove 130. With such a setting, it is convenient to pour the colloid part 300 into the fixing groove 130 of the bracket part 100 during injection molding.
[0081] In this embodiment, referring to Figures 4 - 9As shown, the ratio of the maximum cross-section of the membrane hole 210 to the minimum cross-section of the fixing groove 130 is greater than or equal to 1:10 and less than or equal to 9:10. For example, the ratio of the maximum cross-section of the membrane hole 210 to the minimum cross-section of the fixing groove 130 can be set to 1:10, 2:10, 3:10, 4:10, 5:10, 6:10, 7:10, 8:10, 9:10. Within this range, on the one hand, it is convenient for the colloid part 300 to be injected into the fixing groove 130 from the membrane hole 210, and on the other hand, it can also well fix the bracket part 100 and the membrane part 200 to each other.
[0082] In this embodiment, referring to Figure 8 , Figure 10 and as shown in 12, the fixing groove 130 includes a first groove body 131 and a second groove body 132 that communicate with each other. The first groove body 131 is disposed on the side of the bracket body 110 close to the folding screen 21, and the second groove body 132 is disposed on the first surface 121 of the boss 120; the first groove body 131 or the second groove body 132 is arranged to decrease from the side facing the membrane part 200 to the side facing away from the membrane part 200, and the colloid part 300 covers the first groove body 131 and the second groove body 132. In other embodiments, the first groove body 131 and the second groove body 132 are arranged to decrease from the side facing the membrane part 200 to the side facing away from the membrane part 200, and the colloid part 300 covers the first groove body 131 and the second groove body 132.
[0083] Referring to Figure 12 shown, since the first groove body 131 and the second groove body 132 are connected and communicate with each other, the colloid part 300 can cover the entire membrane part 200 on one side of the membrane hole 210, so that the fixing between the bracket part 100 and the membrane part 200 is more firm. In addition, since the first groove body 131 or the second groove body 132 is arranged to decrease from the side facing the membrane part 200 to the side facing away from the membrane part 200, when the colloid part 300 detaches from the first groove body 131 or the second groove body 132, the edge of the first groove body 131 or the second groove body 132 provides a reverse thrust to prevent the colloid part 300 from detaching.
[0084] In this embodiment, referring to Figure 6 , Figure 7 and Figure 8 shown, a perforation 140 is further provided in the bracket body 110. One end of the perforation 140 communicates with the first groove body 131. At least part of the structure of the colloid part 300 is located in the perforation 140, and the cross-section of the perforation 140 is arranged to gradually increase from the first groove body 131 in the direction away from the folding screen 21.
[0085] Based on the above settings, when the colloid part 300 detaches from the first groove body 131, it will be blocked by the colloid part 300 located in the perforation 140, so that the colloid part 300 is more difficult to separate from the first groove body 131.
[0086] In one embodiment, as shown in Figure 8 , Figure 10 and Figure 11 , the first groove body 131 includes a first groove unit 131A and a second groove unit 131B that communicate with each other. The first groove unit 131A communicates with the second groove body 132. One end of the through hole 140 communicates with the second groove unit 131B, and at least part of the structure of the colloid is located in the through hole 140; along the thickness direction of the bracket body 110, there is a non-overlapping part between the orthographic projections of the through hole 140 and the second groove unit 131B.
[0087] Based on the above settings, when the colloid part 300 detaches from the first groove body 131, the non-overlapping part between the orthographic projections of the through hole 140 and the second groove unit 131B will provide a reverse blocking force, so that the colloid part 300 is less likely to be separated from the first groove body 131, thereby enhancing the stability of the screen pressing structure 10.
[0088] This application also proposes an electronic device 20. As shown in Figure 1 , Figure 2 and Figure 3 , the electronic device 20 includes: a folding screen 21, a middle frame 22, and the screen pressing structure 10 as described in the above embodiment. The folding screen 21 is connected to the middle frame 22, and the middle frame 22 is provided with an avoidance groove 23 facing the folding screen 21; the screen pressing structure 10 includes a bracket body 110 and a boss 120 that are connected to each other, and the avoidance groove 23 is provided corresponding to the connection part of the bracket body 110 and the boss 120.
[0089] When the electronic device 20 falls from a height, especially when the electronic device 20 falls from a height in a folded state, the middle frame 22 is recessed inward, thereby pressing the screen pressing structure 10 closer to the folding screen 21, and then damaging the folding screen 21. In this application, by providing the avoidance groove 23 on the middle frame 22 and arranging the avoidance groove 23 corresponding to the connection part of the bracket body 110 and the boss 120, when the middle frame 22 is recessed inward, due to the presence of the avoidance groove 23, it is possible to prevent the screen pressing structure 10 from approaching the folding screen 21, so that the folding screen 21 will not be damaged, thereby achieving the effect of protecting the folding screen 21.
[0090] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
