Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a display screen module and an electronic device. Background Art

[0002] In order to ensure the reliability of the entire structure of the electronic device, a fluid adhesive is generally applied between the display screen and the structural member to bond and fix the display screen and the structural member.

[0003] On the one hand, the bonding width between the display screen and the structural parts needs to meet the requirements of bonding reliability; on the other hand, the fluid adhesive has fluidity, and there will be glue overflow after the display screen and the structural parts are pressed together, which will affect the bonding width. The bonding position usually affects the display function of the display screen, which can easily lead to the difficulty in achieving a breakthrough in the ultra-narrow bezel and full-screen display effect of the whole machine. Utility Model Content

[0004] The present application provides a display screen module and an electronic device, which can achieve a narrow frame of the electronic device.

[0005] In a first aspect, a display screen module is provided, comprising a structural member and a display screen, the structural member comprising a bonding surface and an inner side surface, the bonding surface being parallel to the main plane of the display screen and being used for bonding and fixing to the display screen, the inner side surface being perpendicular to the main plane of the display screen, and the inner side surface comprising a first groove body; the display screen comprises a chamfer, the chamfer being arranged at the periphery of the display screen and at a side of the display screen close to the bonding surface, the shortest distance from an end of the first groove body close to the display screen in a first direction to the bonding surface is less than or equal to the shortest distance from an end of the chamfer body far from the bonding surface in the first direction to the bonding surface, and the first direction is perpendicular to the main plane of the display screen.

[0006] In the embodiment provided by the present application, the inner side of the structural member includes a first groove body. When the display screen is bonded and fixed to the structural member, the first groove body can accommodate at least part of the fluid adhesive overflowing from the glue spot area, thereby reducing the amount of fluid adhesive overflowing from the glue spot area toward the center of the display screen, reducing the bonding width between the display screen and the structural member, increasing the effective display area of ​​the display screen, and realizing a narrow frame of the electronic device. In addition, the shortest distance from the end of the first groove body close to the display screen in the first direction to the bonding surface is less than or equal to the shortest distance from the end of the chamfer of the display screen away from the bonding surface in the first direction to the bonding surface, so that the fluid adhesive does not provide bonding force to the inner side of the display screen, alleviating the glue overflow problem on the inner side of the structural member.

[0007] In combination with the first aspect, in certain implementations of the first aspect, the first groove body includes a first bottom surface, the first bottom surface intersects with the bonding surface, and an angle θ between the first bottom surface and the bonding surface satisfies: 90°<θ≤180°.

[0008] In the embodiment provided in the present application, the angle θ between the first bottom surface and the bonding surface satisfies 90°<θ≤180°, which can make the fluid adhesive in the first area overflow in the horizontal direction, thereby alleviating the overflow problem on the inner side of the structural member; and when the angle θ between the first bottom surface and the bonding surface satisfies 90°<θ<180°, that is, when the first bottom surface is inclined, the fluid adhesive can overflow into the first groove body more easily and is not easy to overflow to the outside of the structural member, thereby improving the overflow yield rate; the inclined setting of the first bottom surface can also ensure the wall thickness of the structural member and reduce the influence of the opening of the first groove body on the strength of the structural member.

[0009] In combination with the first aspect, in certain implementations of the first aspect, an angle θ between the first bottom surface and the bonding surface satisfies: 135°≤θ≤180°.

[0010] In the embodiment provided in the present application, the angle θ between the first bottom surface and the bonding surface satisfies 135°≤θ≤180°, which can further improve the overflow yield rate and reduce the influence of the groove on the strength of the structural member.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the shortest distance d between an end of the first groove body away from the display screen in the second direction and the inner side surface satisfies 0mm<d≤0.4mm, and the second direction is perpendicular to the inner side surface.

[0012] In the embodiment provided in the present application, the shortest distance d between the end of the first groove body away from the display screen in the second direction and the inner side surface satisfies 0mm<d≤0.4mm, which can reduce the influence of the first groove body on the strength of the structural member.

[0013] In combination with the first aspect, in certain implementations of the first aspect, a shortest distance d between an end of the first slot body in the second direction away from the display screen and the inner side surface satisfies 0.2 mm≤d≤0.4 mm.

[0014] In combination with the first aspect, in some implementations of the first aspect, the first slot body includes a first side surface, the first side surface intersects with the first bottom surface, and the first side surface is arc-shaped.

[0015] In the embodiment provided in the present application, the first side surface of the first groove body is arc-shaped, so that the first groove body can accommodate more fluid adhesive, and can reduce the stress concentration on the side wall of the structural member, thereby improving the strength of the structural member.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the bonding surface includes a first area, which is a glue dot area on the bonding surface; the display screen includes a first end surface, which is a surface of the display screen that is opposite to the inner surface; and the projection of the first end surface along the first direction is located within the first area.

[0017] In the embodiment provided in the present application, the projection of the first end surface of the display screen along the first direction is located in the first area, which can reduce the bonding width between the structural member and the display screen, increase the effective display area of ​​the display screen, and achieve a narrow frame of the electronic device.

[0018] In combination with the first aspect, in certain implementations of the first aspect, the first groove body includes a first top surface, which is a surface of the first groove body that intersects with the inner side surface, and the first top surface is arranged at an angle with the first bottom surface, and the angle between the first top surface and the first bottom surface is an acute angle.

[0019] In the embodiment provided in the present application, the first top surface and the first bottom surface of the first groove body are arranged at an angle, and the angle between the first top surface and the first bottom surface is an acute angle, which can reduce the amount of thinning of the structural member when opening the first groove body and alleviate the impact of the opening of the first groove body on the strength of the structural member.

[0020] In combination with the first aspect, in some implementations of the first aspect, the first slot body is trapezoidal.

[0021] In a second aspect, an electronic device is provided, comprising a display screen module as described in the first aspect or any possible implementation manner of the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0035] Figure 11 is a schematic diagram of the structure of an electronic device 100 provided by the present application. The electronic device 100 may include a display screen 10 and a structural member 20, and the display screen 10 and the structural member 20 may be fixedly connected by bonding. The structural member 20 may include a first portion 21 and a second portion 22. The first portion 21 may be a portion of the structural member 20 parallel to the y-axis direction shown in the figure, and the first portion 21 may be the left and right side frames of the electronic device 100. The second portion 22 may be a portion of the structural member 20 parallel to the x-axis direction shown in the figure, and the second portion 22 may be the upper and lower side frames of the electronic device 100. Both the first portion 21 and the second portion 22 may be fixedly connected to the display screen 10 by bonding.

[0036] Figure 2 It is a schematic diagram of a bonding method of an electronic device in the prior art, and the Figure 2 Can be Figure 1 The schematic diagram of the cross-sectional structure of the first part 21 and the display screen 10 of the electronic device 100 shown in the figure may also be a schematic diagram of the cross-sectional structure of the second part 22 and the display screen 10 in the xy plane. The bonding structure between the second part 22 of the structural member 20 and the display screen 10 may be similar to the bonding structure between the first part 21 and the display screen 10. Figure 2 As shown, the fluid adhesive is all on the bonding surface 211 of the structural member 20, that is, on the bottom surface of the structural member 20. The bonding surface 211 includes a first area 2111 and a second area 2112. The first area 2111 is a natural glue dispensing area, that is, an area where the fluid adhesive 30 is dispensed, and the second area 2112 is an overflow glue area. After dispensing glue on the structural member 20, the display screen 10 and the structural member 20 are pressed together so that the display screen 10 and the structural member 20 are stably bonded. The fluid adhesive 30 dispensed on the first area 2111 will overflow to both sides of the first area 2111 to form the second area 2112. The second area 2112 may include the illustrated area 2112A and the illustrated area 2112B. After the fluid adhesive 30 is cured, the bonding width between the structural member 20 and the display screen 10 is the sum of the natural glue dispensing width and the overflow glue width, that is, the sum of the dimensions of the illustrated first area 2111 and the second area 2112 in the x direction.

[0037] Since the fluid adhesive is all on the bonding surface of the structural member, the width occupied by the fluid adhesive is relatively large, which affects the display area of ​​the screen.

[0038] Therefore, it is necessary to provide an electronic device, the bonding method of which can enable the electronic device to have a narrower frame.

[0039] Figure 3 is a schematic cross-sectional view of a structural member 20 of the electronic device. The structural member 20 may be Figure 1The first part 21 or the second part 22 of the structural member 20 in the electronic device shown is, for example, Figure 3 Can be Figure 1 A schematic structural diagram of the first portion 21 of the middle structural member 20 along the AA section.

[0040] like Figure 3 As shown, the structural member 20 may include a bonding surface 211 and an inner side surface 212. The bonding surface 211 may be parallel to the main plane of the display screen 10 and may be used to bond and fix to the display screen 10. The bonding surface 211 may be parallel to the xy plane shown in the figure. The inner side surface 212 may be perpendicular to the bonding surface 211, or in other words, the inner side surface 212 may be perpendicular to the display screen 10, and the inner side surface 212 may be parallel to the yz plane shown in the figure. The inner side surface 212 may include a first groove body 213, and the first groove body 213 may be a concave portion on the inner side surface 212.

[0041] It should be noted that the main plane of the display screen 10 can be a surface with a larger plane area of ​​the display screen 10. For example, the display screen 10 can be a straight screen or a curved screen. The main plane of the straight screen can be the entire straight surface part of the straight screen. The curved screen can include a curved surface part and a straight surface part. The straight surface part occupies a larger area and the curved surface part occupies a smaller area. The main plane of the curved screen can be the plane where the straight surface part is located. Similarly, the inner side surface 212 is perpendicular to the bonding surface 211, which can be the main plane of the inner side surface 212 and the main plane of the bonding surface 211. That is, the surface with a larger plane area of ​​the inner side surface 212 is perpendicular to the surface with a larger plane area of ​​the bonding surface 211. In addition, the main plane of the display screen is parallel to the xy plane shown in the figure, and can be approximately parallel, allowing a certain angle error, such as 0.1° to 1°. Similarly, the inner side surface 212 is perpendicular to the bonding surface 211, which can mean that the inner side surface 212 is approximately perpendicular to the bonding surface 211. The angular relationships such as parallel and perpendicular in the embodiments of the present application do not represent absolute parallelism or perpendicularity, and angle errors are allowed.

[0042] Figure 4 for Figure 3The cross-sectional structure diagram after the structural member 20 and the display screen 10 are bonded is shown. The structural member 20 and the display screen 10 can constitute a display screen module. The bonding surface 211 can include a first area 2111. The first area 2111 can be a glue-dispensing area on the bonding surface 211, that is, an area on the structural member 20 for coating the fluid adhesive 30. The display screen 10 can include a second bottom surface 11 and a first end surface 12. The first end surface 12 can be arranged opposite to the inner side surface 212. The second bottom surface 11 can be arranged opposite to the bonding surface 211, and the second bottom surface 11 can be bonded and fixed to the bonding surface 211 through the adhesive on the first area 2111. In other words, when the display screen 10 is bonded and fixed to the structural member 20, the projection of the display screen 10 along the first direction can at least partially overlap with the first area 2111. The first direction can be a direction perpendicular to the display screen 10, and the first direction is the direction of the y-axis shown in the figure.

[0043] When the display screen 10 and the structural member 20 are pressed together, the fluid adhesive 30 on the first area 2111 can overflow in the horizontal direction, that is, it can overflow in the negative direction of the x-axis and the positive direction of the x-axis, respectively, to form an overflow area 2112A and an overflow area 2112B, respectively, and the overflow area can also be called a second area 2112, and the second area 2112 can include the overflow area 2112A and the overflow area 2112B. The fluid adhesive overflowing from the first area 2111 in the negative direction of the x-axis can be contained in the first groove 213, that is, the first bottom surface 2131 of the first groove 213 can overlap at least partially with the overflow area 2112A, and the first bottom surface 2131 can be the surface of the first groove 213 that intersects with the bonding surface 211. Since the first groove 213 is located on the side wall of the structural member 20 and does not occupy the display area of ​​the display screen 10, the bonding width between the display screen 10 and the structural member 20 can be the sum of the size of the first area 2111 in the x-axis direction and the size of the overflow area 2112B in the x-axis direction. The first groove 213 accommodates at least part of the fluid adhesive overflowing from the first area 2111, so that the amount of fluid adhesive overflowing from the first area 2111 toward the center area of ​​the display screen 10 is reduced, that is, the amount of fluid adhesive overflowing in the positive direction of the x-axis is reduced, thereby reducing the bonding width between the display screen 10 and the structural member 20, increasing the display area of ​​the display screen 10, and realizing a narrow frame of the electronic device.

[0044] It should be noted that Figure 4 The fluid adhesive 30 is marked with a shaded portion in the figure, and is marked with shades of different patterns in the figure to distinguish the positions corresponding to the glue dot area and the glue overflow area. No limitation should be made to the fluid adhesive 30 itself. The components of the fluid adhesive 30 corresponding to the two shaded patterns before and after curing can be the same, which is similar to the following.

[0045] Continue to see Figure 4 In the structure shown, in some embodiments, the display screen 10 may include a chamfer 121, which may be arranged at the periphery of the display screen 10, and may be arranged at a side of the display screen 10 close to the bonding surface 211, that is, may be arranged at the lower edge of the display screen 10. The shortest distance from the end of the first groove body 213 close to the display screen 10 in the first direction to the bonding surface 211 may be less than or equal to the shortest distance from the end of the chamfer 121 far from the bonding surface 211 in the first direction to the bonding surface 211. The end of the first groove body 213 close to the display screen 10 in the first direction may be the intersection of the first top surface 2133 of the first groove body 213 and the inner side surface 212, that is, the highest point of the first groove body 213 in the first direction, and the first top surface 2133 and the first bottom surface 2131 may be arranged at the two ends of the first side surface 2132 along the first direction, respectively. The shortest distance from the end of the first slot 213 close to the display screen 10 in the first direction to the adhesive surface 211 is the distance between the end of the first slot 213 close to the display screen 10 in the first direction and the adhesive surface 211 in the first direction. Figure 3 and Figure 4 Taking the structural member 20 shown in FIG. 1 as an example, the shortest distance from the end of the first groove 213 close to the display screen 10 in the first direction to the bonding surface 211 is Figure 3 Similarly, the shortest distance from the end of the chamfer 121 away from the bonding surface 211 to the bonding surface 211 may be the distance between the end of the chamfer 121 away from the bonding surface 211 and the bonding surface 211 in the first direction. Figures 5 to 8 In the structural member 20 described, the relationship between the shortest distance from the end of the first groove 213 close to the display screen 10 in the first direction to the bonding surface 211 and the shortest distance from the end of the chamfer 121 far from the bonding surface 211 in the first direction to the bonding surface 211 is as follows: Figure 3 and Figure 4 Similar to the .

[0046] It should be noted that the shortest distance from the end of the first groove 213 in the first direction close to the display screen 10 to the bonding surface 211 is less than or equal to the shortest distance from the end of the chamfer 121 in the first direction away from the bonding surface 211 to the bonding surface 211, which may mean that the highest point of the first groove 213 in the first direction is lower than the highest point of the chamfer 121 in the first direction, or that the highest point of the first groove 213 in the first direction is flush with the highest point of the chamfer 121 in the first direction. Figure 4The highest point of the first groove body 213 in the first direction is flush with the highest point of the chamfer 121 in the first direction, and this should not be used to limit the embodiments of the present application. In addition, since the display screen 10 may have a thickness, that is, a size in the first direction, a chamfer may also be provided on the side of the display screen 10 away from the bonding surface 211, that is, the chamfer 122 shown in the figure may also be provided at the position of the upper edge of the display screen 10, so that the touch feel of the display screen 10 is softer. In the embodiments of the present application, it is only necessary to make the highest point of the first groove body 213 in the first direction lower than the highest point of the chamfer 121 on the lower edge of the display screen 10 in the first direction, or to make it flush with the highest point of the chamfer 121 on the lower edge of the display screen 10 in the first direction.

[0047] It should be noted that the display screen may include a protective layer and a display layer, the protective layer may be, for example, a glass cover plate, the display layer may be used to display information such as images and text, or may also integrate a touch function, etc., and the display screen in the embodiment of the present application may be the protective layer. The chamfers 121 and 122 shown in the figure are straight-edged, and the chamfers 121 and 122 may also be rounded, for example, by rounding the edges of the display screen 10, and the present application does not limit the structure of the chamfers.

[0048] In the embodiment provided by the present application, the shortest distance from the end of the first groove 213 close to the display screen 10 in the first direction to the bonding surface 211 is less than or equal to the shortest distance from the end of the chamfer 121 far from the bonding surface 211 in the first direction to the bonding surface 211, so that the fluid adhesive does not provide bonding force to the inner side surface 212 of the display screen 10, thereby alleviating the problem of glue overflow on the inner side surface 212 of the structural component 20.

[0049] In some embodiments, the display screen 10 may include a first end surface 12, which may be a surface of the display screen 10 arranged opposite to the inner side surface 212, and the first end surface 12 may be parallel to the yz plane shown in the figure, and the projection of the first end surface 12 along the first direction may be located in the first area 2111.

[0050] See also Figures 4 to 8 In the structure shown, if the projection of the first end surface 12 along the first direction is located outside the first area 2111, that is, the first end surface 12 is located on the left side of the first area 2111, the bonding width between the display screen 10 and the structural member 20 can be the sum of the size of the first area 2111 in the x-axis direction, the size of the overflow area 2112B in the x-axis direction, and the size between the end of the first area 2111 close to the inner side surface 212 and the first end surface 12 in the x-axis direction. Figures 4 to 8The end of the first region 2111 close to the inner side surface 212 of the structural member 20 is located at the same position in the x-axis direction as the first end surface 12, and the bonding width between the display screen 10 and the structural member 20 is the sum of the dimensions of the first region 2111 and the overflowing glue region 2112B in the x-axis direction. The projection of the first end surface 12 along the first direction can be located in the first region 2111, which can reduce the bonding width between the display screen 10 and the structural member 20 and increase the effective display area of ​​the display screen 10.

[0051] It should be noted that Figures 4 to 8 Taking the example that one end of the first region 2111 close to the inner side surface 212 and the first end surface 12 are located at the same position in the x-axis direction, the structure of the structural member 20 is introduced. The one end of the first region 2111 close to the inner side surface 212 and the first end surface 12 may also be located at different positions in the x-axis direction. Figure 4 In the structural member shown, the end of the first region 2111 close to the inner side surface 212 can be located on the left side of the first end surface 12, so that the projection of the first end surface 12 along the first direction is located within the range of the first region 2111. For example, the fluid adhesive can be applied from the corresponding position of the inner side surface 212 on the x-axis toward the direction close to the center of the display screen 10.

[0052] The projection of the first end surface 12 along the first direction may also be located outside the area where the first region 2111 is located. For example, when the first bottom surface 2131 of the first groove body 213 is tilted downward relative to the bonding surface 211, the intersection of the first bottom surface 2131 and the bonding surface 211 may be located on the right side of the first end surface 12 (not shown in the figure), or in other words, the projection of the first end surface 12 along the first direction may be located in the area where the first bottom surface 2131 is located. In this example, the first area 2111 may extend from the intersection of the first bottom surface 2131 and the bonding surface 211 toward the center of the display screen 10.

[0053] In some embodiments, the first groove body 213 may include a first bottom surface 2131 , the first bottom surface 2131 may intersect with the bonding surface 211 , and an angle θ between the first bottom surface 2131 and the bonding surface 211 may satisfy: 90°<θ≤180°.

[0054] When the angle θ between the first bottom surface 2131 and the bonding surface 211 is 180°, the first bottom surface 2131 and the bonding surface 211 may be located on the same plane. Figure 4 The structure shown.

[0055] When the angle θ between the first bottom surface 2131 and the bonding surface 211 is 90°<θ<180°, the first bottom surface 2131 may be tilted downward relative to the bonding surface 211. The angle between the first bottom surface 2131 and the bonding surface 211 may be the angle between the first bottom surface 2131 and the bonding surface 211 in the direction of the structural member facing away from the display screen 10, for example Figures 5 to 8 The structure shown.

[0056] Exemplarily, the angle θ between the first bottom surface 2131 and the bonding surface 211 can be 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175° or the like.

[0057] It should be noted that the above range is only used as an example to illustrate the range of the angle between the first bottom surface 2131 and the bonding surface 211, and the size of the angle should not be limited.

[0058] In the embodiment provided in the present application, the angle range between the first bottom surface 2131 and the bonding surface 211 satisfies 90°<θ≤100°, which can make the fluid adhesive in the first area 2111 more easily overflow into the first groove body 213 and less likely to overflow to the outside of the structural component 20, so that the overflow adhesive yield rate can be more easily improved.

[0059] In some embodiments, the angle θ between the first bottom surface 2131 and the bonding surface 211 may be in the range of 135°≤θ≤180°.

[0060] In the embodiment provided in the present application, the angle θ between the first bottom surface 2131 and the bonding surface 211 can be in the range of 135°≤θ≤180°, which can not only improve the overflow yield of the structural component, but also ensure the structural strength of the structural component.

[0061] It should be noted that Figures 3 to 8 The first bottom surface 2131 of the first groove body 213 shown in the figure intersects with the bonding surface 211 of the structural member 20. The first bottom surface 2131 may not intersect with the bonding surface 211, but intersect with the inner side surface 212 of the structural member 20 (not shown in the figure). Figure 3 and Figure 4 In the structural member 20 shown, the first bottom surface 2131 is parallel to the bonding surface 211 and is located on the same plane. The position of the first bottom surface 2131 can be translated upward along the z-axis direction so that the first bottom surface 2131 intersects with the inner side surface 212. When milling the first groove body 213, the milling cutter can be used to mill the inner side surface 212 along the negative direction of the x-axis from a position a certain distance away from the bonding surface 211 to obtain the structure. Figures 5 to 8The structure of the first slot body 213 shown is similar to this, and the present application does not limit this. It is only necessary that the setting position of the first slot body 213 allows the fluid adhesive in the first area 2111 to overflow in the horizontal direction and be accommodated in the first slot body 213.

[0062] In some embodiments, the shortest distance d between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 may satisfy 0mm<d≤0.4mm. The end of the first groove body 213 away from the display screen 10 in the second direction may be the position of the first groove body 213 farthest from the display screen 10, and the shortest distance between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 is the distance in the second direction between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212. The second direction may be perpendicular to the inner side surface 212, and the second direction is the x-axis direction shown in the figure.

[0063] Exemplarily, the shortest distance d between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 can be 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm or the like.

[0064] In some embodiments, the shortest distance d between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 may satisfy 0.2 mm≤d≤0.4 mm.

[0065] for Figure 3 and 4 In the structural member shown, the first slot body 213 is a trapezoid, and the first slot body 213 can be formed by milling the inner side surface 212 of the structural member 20 in the horizontal direction with the bonding surface 211 as the bottom surface using a milling cutter, and the first side surface 2132 of the first slot body 213 is perpendicular to the bonding surface 211, and the first slot body 213 can be a trapezoidal structure. In this example, the shortest distance between the end of the first slot body 213 away from the display screen 10 in the second direction and the inner side surface 212 can be the distance between the first side surface 2132 and the inner side surface 212 in the second direction.

[0066] for Figure 5In the structural member shown, the angle between the first bottom surface 2131 of the first groove body 213 and the bonding surface 211 is an obtuse angle, and the first side surface 2132 is perpendicular to the first bottom surface 2131. The first groove body 213 can be formed by milling the inner side surface 212 of the structural member 20 with a straight-edge dovetail cutter at a certain angle downward, and the first groove body 213 can be approximately a trapezoidal structure. In this example, the shortest distance between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 can be the distance between the upper end of the first side surface 2132 and the inner side surface 212 in the second direction.

[0067] for Figure 6 In the structural member shown, the angle between the first bottom surface 2131 of the first groove body 213 and the bonding surface 211 is an obtuse angle, and the first side surface 2132 is an arc surface. The first groove body 213 can be formed by using a dovetail cutter with an arc edge to mill the inner side surface 212 of the structural member 20 at a certain angle downward. In this example, the shortest distance between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 can be the distance between the tangent point of the straight line parallel to the z-axis direction and the first side surface 2132 and the inner side surface 212 in the second direction.

[0068] for Figure 7 In the structural member shown in the figure, the angle between the first bottom surface 2131 of the first groove body 213 and the bonding surface 211 is an obtuse angle, and the first side surface 2132 is perpendicular to the first bottom surface 2131. The first groove body 213 can be formed by milling the inner side surface 212 of the structural member 20 at a certain angle downward with a straight-edge T-shaped cutter. The first groove body 213 can also be a trapezoidal structure. In this example, Figure 5 Similar to the structural member 20 shown, the shortest distance between the end of the first slot 213 away from the display screen 10 in the second direction and the inner side surface 212 may be the distance between the upper end of the first side surface 2132 and the inner side surface 212 in the second direction.

[0069] for Figure 8 In the structural member shown in the figure, the angle between the first bottom surface 2131 of the first groove body 213 and the bonding surface 211 is an obtuse angle, and the first side surface 2132 is an arc surface. The first groove body 213 can be formed by milling the inner side surface 212 of the structural member 20 at a certain angle downward using a T-shaped cutter with an arc edge. The first groove body 213 can be a runway-shaped structure. Figure 6 Similar to the structural member 20 shown, the shortest distance between the end of the first slot 213 away from the display screen 10 in the second direction and the inner side surface 212 can be the distance between the tangent point of a straight line parallel to the z-axis direction and the first side surface 2132 and the inner side surface 212 in the second direction.

[0070] In the embodiment provided in the present application, the shortest distance d between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 satisfies 0mm<d≤0.4mm, which can ensure the structural strength of the structural component while achieving a narrow frame effect.

[0071] In some embodiments, the shortest distance d between the end of the first groove body 213 away from the display screen 10 in the second direction and the inner side surface 212 satisfies 0.2 mm≤d≤0.4 mm.

[0072] It should be noted that the first groove body 213 can be processed by the above-mentioned milling method, and can also be processed by injection molding process, and this application does not limit this.

[0073] In some embodiments, the first side surface 2132 may be arc-shaped, such as Figure 6 or Figure 8 The arc-shaped first side surface 2132 may be bent in a direction away from the display screen 10, so that the first side surface 2132 is a convex structure.

[0074] In the embodiment provided in the present application, the first side surface 2132 of the first groove body 213 is arc-shaped, and can accommodate more fluid adhesive than the straight-edge first side surface 2132, thereby further reducing the amount of fluid adhesive overflowing toward the center of the display screen 10 and increasing the effective display area of ​​the display screen; and can make the connection between the first side surface 2132 and the first bottom surface 2131 and the first top surface 2133 smoother, so that the stress concentration on the inner side surface 212 of the structural component 20 is smaller, which can improve the strength of the structural component 20.

[0075] In some embodiments, the structural member 20 may include a first top surface 2133 , and the first top surface 2133 is disposed at an angle to the first bottom surface 2131 , and the angle between the first top surface 2133 and the first bottom surface 2131 may be an acute angle.

[0076] Exemplarily, the angle between the first top surface 2133 and the first bottom surface 2131 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc.

[0077] like Figure 3 and Figure 4 In the structural member shown in the figure, the first top surface 2133 can be a surface inclined downward, or in other words, the angle between the first top surface 2133 and the positive axis of the x-axis is an acute angle. When the first bottom surface 2131 is parallel to the xy plane shown in the figure, the angle between the first top surface 2133 and the first bottom surface 2131 is also an acute angle, such as Figure 3 β indicated in .

[0078] Similarly, Figure 5 and Figure 6 In the structural member shown in FIG. 1 , an angle θ is formed between the first bottom surface 2131 and the bonding surface 211, and the angle between the first bottom surface 2131 and the bonding surface 211 is an obtuse angle. The first top surface 2133 can be arranged obliquely downward to form an angle with the first bottom surface 2131, and the angle is an acute angle, such as Figure 5 and Figure 6 Indicated by β in .

[0079] It should be noted that the angle between the first top surface 2133 and the first bottom surface 2131 may not be an acute angle. Figure 7 or Figure 8 In the structure shown, the first top surface 2133 and the first bottom surface 2131 may also be parallel to each other. For example, when the first groove body 213 is milled by a T-shaped cutter, the first top surface 2133 and the first bottom surface 2131 may also be parallel to each other. It is only necessary to ensure that the first groove body 213 can accommodate the fluid adhesive overflowed from the first area 2111, and the present application does not limit this.

[0080] In the embodiment provided in the present application, the angle between the first top surface 2133 and the first bottom surface 2131 is an acute angle, which can reduce the thinning amount of the side wall of the structural component during the milling process or injection molding process of the first groove body 213 while ensuring that the first groove body 213 can accommodate the fluid adhesive overflowing from the first area 2111, thereby ensuring the structural strength of the structural component.

[0081] It should be noted that in Figures 3 to 8 The structural member 20 described is Figure 1 In the first part 21 of the electronic device shown, the first slot body 213 can be arranged on the entire first part 21 along the y-axis direction, or in other words, the left and right side frames of the electronic device can respectively include a first slot body 213, and the first slot body 213 can extend along the y-axis direction. The first slot body 213 can also be arranged at intervals on the first part 21, or in other words, the left and right side frames of the electronic device can respectively include multiple first slot bodies 213, and the multiple first slot bodies 213 are arranged at intervals along the y-axis direction. The sizes of the multiple first slot bodies 213 along the y-axis direction can be the same or different, the shapes of the multiple first slot bodies 213 can be the same or different, and the number and shape of the first slot bodies 213 arranged on the left and right side frames of the electronic device can be the same or different. Similarly, in the structural member 20 is Figure 1The second part 22 of the electronic device shown, that is, the number of the first slots 213 of the upper and lower side frames of the electronic device can be one or more, and the number and shape of the first slots 213 on the upper and lower side frames can be the same or different, which is not limited in the present application. The present application also provides an electronic device, which can include Figures 3 to 8 Any display screen module described in Figures 3 to 8 Any one of the structural members 20 described in the specification, or may include a plurality of first slot bodies 213 structures in the above-mentioned structural member 20, the electronic device may also include a display screen 10, the display screen 10 is bonded and fixed to the structural member 20, and the cross-sectional structure of the electronic device may be Figures 4 to 8 Any of the ones shown.

[0082] The electronic device provided in the embodiments of the present application may be a mobile phone, a tablet computer, a laptop computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), or other mobile terminals with a display screen. The present application does not limit the type of electronic device.

[0083] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
