Technical Field

[0001] The present application belongs to the technical field of electronic products, and specifically relates to an electronic device. Background Art

[0002] With the rapid development of electronic devices, the form of electronic devices is becoming more and more diverse. At present, the trend of electronic devices is to become thinner and lighter, but the thinning of the whole machine will bring many other uncontrollable factors, such as the whole machine structure is not resistant to pressure, not resistant to falling and other problems.

[0003] At present, the front camera module is compressed by a motherboard bracket and foam on the side away from the light entrance area. When the electronic device is subjected to external pressure, the pressure is transmitted to the front camera module through the motherboard bracket, which can easily cause damage to the front camera module and cannot guarantee the reliability of the front camera module. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide an electronic device that can ensure the reliability of the front camera module.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0007] The cover plate and the frame body are arranged to form a first receiving space, the pressing member, the camera module and the positioning bracket are received in the first receiving space, and the pressing member and the camera module are sequentially stacked in a direction toward the cover plate, and the camera module is fixed on the positioning bracket;

[0008] Wherein, the pressing member includes a middle area and an edge area, and the middle area is a convex hull structure;

[0009] The convex hull structure protrudes toward the cover plate, and the orthographic projection of the convex hull structure on the plane where the cover plate is located covers the camera module.

[0010] In an embodiment of the present application, the electronic device includes a cover plate, a pressing member, a camera module, a positioning bracket and a frame; the cover plate and the frame are surrounded to form a first receiving space, the pressing member, the camera module and the positioning bracket are received in the first receiving space, and the pressing member and the camera module are stacked in sequence in the direction toward the cover plate, and the camera module is fixed on the positioning bracket; the pressing member includes a middle area and an edge area, and the middle area is a convex hull structure; the convex hull structure protrudes toward the cover plate, and the positive projection of the convex hull structure on the plane where the cover plate is located covers the camera module. In this way, there is a gap between the side of the convex hull structure facing the camera module and the camera module. When the pressing member is squeezed, the gap can provide a certain buffering effect, provide space for the deformation of the pressing member, and avoid squeezing the camera module; and when the cover plate is squeezed by external force, if the top of the convex hull structure conflicts with the cover plate, the convex hull structure can disperse part of the pressure, improve the pressure resistance of the pressing member, and can play a better protective role on the camera module, so as to improve the reliability of the camera module in a limited space.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0030] The control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] Please refer to Figures 1 to 4, the embodiment of the present application provides an electronic device, comprising: a cover plate 1, a pressing member 2, a camera module 3, a positioning bracket 4 and a frame 5;

[0032] The cover plate 1 and the frame body 5 are arranged to form a first receiving space, and the pressing member 2, the camera module 3 and the positioning bracket 4 are received in the first receiving space, and the pressing member 2 and the camera module 3 are sequentially stacked in a direction toward the cover plate 1, and the camera module 3 is fixed on the positioning bracket 4;

[0033] The pressing member 2 includes a middle area and an edge area, and the middle area is a convex hull structure 21;

[0034] The convex structure 21 protrudes toward the cover plate 1 , and the orthographic projection of the convex structure 21 on the plane where the cover plate 1 is located covers the camera module 3 .

[0035] like Figure 1 In the figure, the clamping piece 2 is fixedly connected to the frame 5, the camera module 3 is fixedly connected to the positioning bracket 4, and the camera module 3 and the positioning bracket 4 are clamped between the clamping piece 2 and the frame 5; the convex side of the convex structure 21 faces the cover plate 1, and the concave side of the convex structure 21 faces the camera module 3.

[0036] In the above embodiment, the convex structure 21 has a gap between the side facing the camera module 3 and the camera module 3. When the clamping piece 2 is squeezed by external force, the gap can provide a certain buffering effect, provide space for the deformation of the clamping piece 2, and avoid the external force squeezing the camera module 3; moreover, when the cover plate 1 is squeezed by external force, if the top of the convex structure 21 contacts the cover plate 1, the convex structure 21 can disperse part of the pressure, thereby improving the compression resistance of the clamping piece 2, and improving the protective effect of the clamping piece 2 on the camera module 3, thereby improving the reliability of the camera module in a limited space.

[0037] It should be noted that the mainboard bracket (not shown in the figure) cooperates with the frame 5 to support the mainboard. In the conventional solution, the camera module 3 is pressed by injecting rubber into the mainboard bracket. In the embodiment of the present application, the mainboard bracket is provided with a notch in the area where the camera module 3 is located, and the pressing member 2 is provided in the notch. The pressing member 2 does not overlap with the mainboard bracket, so that the camera module 3 is pressed by replacing the mainboard bracket with rubber injection by the pressing member 2, which is conducive to reducing the thickness of the electronic device.

[0038] In some embodiments, Figure 1 In the embodiment, there is a gap between the convex structure 21 and the cover plate 1 ; a support pad 6 is fixedly connected to the edge region on the side facing the cover plate 1 , and the support pad 6 abuts against the cover plate 1 .

[0039] Optionally, the support pad 6 is made of polyethylene terephthalate (PET).

[0040] like Figure 3 As shown, the support pad 6 is disposed around the convex structure 21 , and the thickness of the support pad 6 is greater than the height of the convex structure 21 , so that a gap is provided between the top of the convex structure 21 and the cover plate 1 .

[0041] In this embodiment, by abutting the support pad 6 against the cover plate 1, the support pad 6 can provide support force for the cover plate 1 when the cover plate 1 is squeezed or impacted by external force, so as to prevent the risk of damage to the edge of the camera module 3 due to excessive force caused by excessive deformation of the cover plate 1; moreover, the gap between the convex structure 21 and the cover plate 1 is a reserved buffer zone. When the clamping piece 2 is squeezed by external force, the gap can provide space for the deformation of the clamping piece 2 and help to disperse stress, thereby effectively reducing the pressure of the external force on the camera module 3 and improving the reliability of the camera module 3.

[0042] In some embodiments, the pressing member 2 is provided with a plurality of reinforcing ribs 22 on a side facing the cover plate 1 , and the plurality of reinforcing ribs 22 are evenly distributed around the middle area, and each reinforcing rib 22 extends from the middle area to the edge area.

[0043] For example, Figures 2 to 4 As shown, in order to cover the middle area of ​​the clamping piece 2 to the greatest extent, the convex structure 21 is set to an elliptical shape, and four reinforcing ribs 22 are symmetrically arranged around the convex structure 21, with an angle of 90° between two adjacent reinforcing ribs 22, and each reinforcing rib 22 is connected to the convex structure 21 and the edge area of ​​the clamping piece 2 at the same time, so as to enhance the strength of the clamping piece 2.

[0044] It should be pointed out that Figure 2 and Figure 3 This is just an example, and in a specific implementation, the distribution of the reinforcing ribs 22 may also be non-uniform. For example, the convex structure 21 is set to be an ellipse, and four reinforcing ribs 22 are arranged in two rows in parallel on the pressing member 2.

[0045] In some embodiments, Figure 2 In the embodiment, the edge area of ​​the pressing member 2 extends outwardly with multiple edges as connecting ends, and the pressing member 2 is fixedly connected to the frame 5 through the connecting ends;

[0046] like Figure 1 In the embodiment, the pressing member 2 and the frame 5 are arranged to form a second receiving space, and the camera module 3 and the positioning bracket 4 are received in the second receiving space.

[0047] Optionally, the connection method between the connection end and the frame 5 includes but is not limited to: gluing, clamping, bolting, etc.

[0048] In this embodiment, the clamping member 2 is fixedly connected to the frame 5 through the connecting end, so that the camera module 3 and the positioning bracket 4 can be clamped between the frame 5 and the clamping member 2, thereby avoiding position displacement of the camera module 3 due to external force, thereby improving the stability of the camera module 3.

[0049] In some embodiments, Figure 2 and Figure 3 As shown, the connection end includes: a first connection end 71, a second connection end 72, a third connection end 73 and a fourth connection end 74;

[0050] The first connection end 71 is close to the upper frame 51 of the frame body 5, and a slot is provided on the upper frame 51, and the first connection end 71 is engaged with the slot;

[0051] The second connection end 72 is close to the side frame 52 of the frame 5, and the second connection end 72 is adhesively connected to the frame 5;

[0052] The third connection end 73 and the fourth connection end 74 are close to the mainboard of the electronic device, and the third connection end 73 and the fourth connection end 74 are fixedly connected to the frame 5 by bolts.

[0053] Optionally, the frame 5 includes an upper frame 51 and a lower frame (not shown) that are relatively arranged, and two side frames 52 that are relatively arranged. The two side frames, the upper frame 51 and the lower frame are arranged to form the frame 5, and the second connecting end 72 is close to one of the side frames 52.

[0054] In specific implementation, due to the structural limitation of the side frame 52 and the influence of other components, the second connection end 72 is fixedly connected to the side frame 52 by local glue dispensing, and the upper frame 51 is thicker as a whole, but due to space limitations, a card slot can be provided to be connected to the first connection end 71. Bolt holes are provided on the third connection end 73 and the fourth connection end 74, and bolt holes are correspondingly provided on the frame 5, so that the third connection end 73 and the fourth connection end 74 are fixedly connected to the frame 5 by bolts. In this way, the clamping member 2 is connected to the frame 5 through four connection ends, which can ensure the connection stability between the clamping member 2 and the frame 5.

[0055] In some embodiments, the positioning bracket 4 includes: a metal plate 41 and a plastic frame 42, one side of the metal plate 41 is fixedly connected to the plastic frame 42, and the other side of the metal plate 41 is fixedly connected to the frame body 5;

[0056] The plastic frame 42 and the metal plate 41 surround and form an installation space for the camera module 3 to limit the position of the camera module 3 .

[0057] Optionally, the metal plate 41 is a steel sheet.

[0058] like Figures 5 to 7As shown, the metal plate 41 and the plastic frame 42 are integrally formed, and the metal plate 41 and the plastic frame 42 surround and form a receiving space for the camera module 3, which is used to limit the installation position of the camera module 3 and prevent the camera module 3 from shifting.

[0059] It should be pointed out that in the traditional positioning bracket solution with a pure plastic structure, in order to ensure the strength of the positioning bracket, the Z-direction thickness of the positioning bracket is relatively large. In the embodiment of the present application, by designing the positioning bracket 4 as a structure in which a metal plate 41 and a plastic frame 42 are integrally formed, compared with the positioning bracket with a pure plastic structure in the traditional structure, the Z-direction thickness of the positioning bracket 4 can be reduced while ensuring the reliability of the positioning bracket 4. The Z-direction refers to the thickness direction of the electronic device. Moreover, the thinning of the Z-direction thickness of the positioning bracket 4 is conducive to reducing the overall thickness of the electronic device.

[0060] In some embodiments, a light-transmitting area 410 and a glue-dispensing area are provided in the middle area of ​​the metal plate 41, and the metal plate 41 is fixedly connected to the frame 5 through the glue-dispensing area, and the glue-dispensing area surrounds the light-transmitting area 410;

[0061] The edge area of ​​the metal plate 41 is fixedly connected to the plastic frame 42 , and the plastic frame 42 is arranged on a side of the metal plate 41 facing the camera module 3 .

[0062] like Figure 6 As shown, the glue-dispensing area in the metal plate 41 is the annular area E between the plastic frame 42 and the light-transmitting area 410 .

[0063] It should be pointed out that in Figures 8 to 10 In the conventional positioning bracket structure, the glue spot area is the edge area D extending outward in the figure. The embodiment of the present application cancels the edge area D and uses the annular area E between the plastic frame 42 and the light-transmitting area 410 as the glue spot area, which is conducive to making the camera module 3 closer to the frame 5; moreover, the combination of the metal plate 41 and the plastic frame 42 can increase the strength of the positioning bracket 4, realize the reduction of the thickness of the plastic frame 42 of the positioning bracket 4, and make the camera module 3 closer to the frame 5. In this way, the pole hole on the screen 8 can be closer to the edge of the screen 8, which is conducive to increasing the display area of ​​the screen.

[0064] like Fig.15 As shown in the exploded view of the electronic device, the light-transmitting area 410 opened on the positioning bracket 4, the light-entering area 80 opened on the screen 8 and the light-transmitting hole opened on the frame 5 are all located on the optical axis of the camera module 3 to facilitate light to enter the camera module 3.

[0065] Furthermore, in order to increase the compressive strength of the cover plate 1 and improve the reliability of the camera module, a reinforcement plate 11 is added to a part of the cover plate 1 .

[0066] like Fig.11In the embodiment, the cover plate 1 is provided with a reinforcing plate 11 in the position area corresponding to the camera module 3, and the cover plate 1 is fixedly connected to the frame 5 through the adhesive backing area 12. Optionally, the reinforcing plate 11 is a steel sheet.

[0067] In some embodiments, the cover plate 1 is provided with a groove 10 on a side facing the pressing member 2;

[0068] A reinforcing plate 11 is fixedly connected in the groove 10 , and the thickness of the reinforcing plate 11 is greater than the depth of the groove 10 .

[0069] For example, Fig.12 As shown, the cover plate 1 is thinned in a local area on the side facing the pressing member 2 to form a groove 10 , and a reinforcing plate 11 is placed in the groove 10 , and a part of the structure of the reinforcing plate 11 protrudes from the surface of the cover plate 1 .

[0070] For example, the local area of ​​the cover plate 1 corresponding to the camera module 3 is thinned by 0.05 mm to form a groove 10, and a 0.1 mm steel sheet is pasted in the groove 10 as a reinforcement plate 11. In this way, the compressive strength of the cover plate 1 can be increased, the reliability of the camera module 3 can be improved, and it is beneficial to reduce the overall thickness of the electronic device.

[0071] In some embodiments, a reinforcing plate 11 is fixedly connected to the surface of the cover plate 1 facing the pressing member 2 .

[0072] For example, Fig.13 In the embodiment, the reinforcing plate 11 is pasted on the surface of the cover plate 1 on the side facing the pressing member 2. For example, a 0.1 mm steel sheet is pasted on the surface of the cover plate 1 on the side facing the pressing member 2 as the reinforcing plate 11, so that the compressive strength of the cover plate 1 can be increased and the reliability of the camera module 3 can be improved.

[0073] In some embodiments, a reinforcing plate 11 is embedded in the side of the cover plate 1 facing the pressing member 2 , and the reinforcing plate 11 is integrally formed with the cover plate 1 .

[0074] For example, Fig.14 In the embodiment, the reinforcing plate 11 is arranged on the side of the cover plate 1 facing the pressing member 2, and the reinforcing plate 11 is integrally formed with the cover plate 1, and the surface of the reinforcing plate 11 and the surface of the cover plate 1 belong to the same plane. In this way, the compressive strength of the cover plate 1 can be increased, the reliability of the camera module 3 can be improved, and the thickness of the entire electronic device can be reduced.

[0075] In some embodiments, the electronic device further comprises: a screen 8 and a protective film 9;

[0076] The screen 8 is arranged on the light incident side of the camera module 3, and a light incident area 80 of the camera module 3 is arranged on the screen 8;

[0077] The protective film 9 is arranged on a side of the screen 8 away from the camera module 3 .

[0078] For example, Fig.15 In the exploded view of the electronic device shown, the screen 8 is arranged on the side of the frame away from the positioning bracket 4, and the screen 8 is fixedly connected to the frame 5, and the protective film 9 is arranged on the side of the screen 8 away from the frame 5, and the protective film 9 is fixedly connected to the screen 8.
