[0002] Thinness and lightness is a development trend of electronic devices such as mobile phones. The thinness and lightness of product forms pose new challenges to the assembly of the front camera module. The front camera module needs to be equipped with a protective structure to reduce the possibility of damage and failure due to impact. In the thin and light form of electronic devices, the reliability of the front camera module and the stacking size of the electronic device in the thickness direction are a contradiction. In order to meet the high reliability of the front camera module, it is necessary to stack a protective structure at the front camera module, and the thickness of the related electronic equipment is difficult to reduce. Summary of the invention

[0003] An embodiment of the present application provides an electronic device, which solves the problem that it is difficult for electronic devices in the related art to have both high reliability of the front camera module and small thickness of the electronic device.

[0004] The embodiment of the present application adopts the following technical solution:

[0005] In a first aspect, an embodiment of the present application provides an electronic device, comprising: a housing, a front camera module, a cover body, and a reinforcement layer. The housing has a light entrance hole. The front camera module is fixed to the housing, and the lens of the front camera module and the light entrance hole are arranged correspondingly. The cover body is connected to the housing, and the cover body has an opening corresponding to the front camera module. The reinforcement layer is embedded in the cover body and covers the opening, and the reinforcement layer and the front camera module are arranged relative to each other.

[0006] The electronic device provided by the embodiment of the present application has a front camera module fixed to the housing, the lens of the front camera module and the light entrance hole of the housing are arranged correspondingly, the cover body is provided with an opening corresponding to the front camera module, the reinforcement layer is embedded in the cover body and covers the opening, the space in the thickness direction of the cover body is effectively utilized, there is no protective structure between the front camera module and the cover body, and the thickness of the electronic device at the front camera module can be made smaller. When the position of the cover body corresponding to the front camera module is impacted, the external impact force acts on the reinforcement layer, and the reinforcement layer absorbs the impact energy to protect the front camera module, which can reduce the situation where the front camera module is damaged and fails due to impact, and meet the high reliability of the front camera module. The stacking structure of the electronic device is simple, the assembly process is simple, and the assembly tolerance accumulation is small.

[0007] When the reinforcing layer and the cover are connected by an adhesive layer, there are five installation dimensions in the thickness direction, namely, the thickness of the reinforcing layer, the thickness of the adhesive layer, the thickness of the cover part, the gap size between the cover and the shell, and the thickness of the shell. When the reinforcing layer and the cover are an integrated structure, there are four installation dimensions in the thickness direction, namely, the thickness of the reinforcing layer, the thickness of the cover part, the gap size between the cover and the shell, and the thickness of the shell. Compared with the six installation dimensions in the thickness direction of electronic devices in the related art, the electronic devices of the present application have fewer installation dimensions in the thickness direction, and the cumulative assembly tolerance is smaller.

[0008] In an optional implementation, when the electronic device is a mobile phone, the housing may be a middle frame and the cover may be a battery cover. The housing serves as a carrier of various components, and a battery, a mainboard, an earpiece, a speaker, etc. may be disposed on the housing. The cover serves as a structural appearance component and may protect components such as a battery and a rear camera module.

[0009] In an optional implementation, when the front camera module is fixed to the housing, the front camera module can be fixed to the housing by using glue or adhesive; or, the front camera module can be fixed to the housing by using tape, the tape is bonded to the housing, and part of the surface of the front camera module is against the housing. Alternatively, the front camera module can also be fixed to the housing by using buckles, fasteners, etc.

[0010] In an optional implementation, one end of the front camera module facing the reinforcement layer is embedded in the opening. When the shell thickness is small, the thickness space of the cover is fully utilized to facilitate the arrangement of the front camera module occupying a certain space, so that the overall structure thickness can be reduced.

[0011] In an optional implementation, one end of the front camera module facing the reinforcement layer is located in the gap between the cover and the shell. Part of the front camera module is located outside the shell and between the cover and the shell, which makes better use of the space in the thickness direction and facilitates the arrangement of the front camera module that occupies a certain space.

[0012] In an optional implementation, one end of the front camera module facing the reinforcement layer is embedded in the light entrance hole. In this way, the front camera module is arranged inside the shell, and the end of the front camera module does not extend beyond the shell. A hole is opened at the position of the cover body corresponding to the front camera module and a reinforcement layer is arranged, and the reinforcement layer provides protection for the front camera module.

[0013] In an optional implementation, the reinforcement layer and the cover body are connected via an adhesive layer.

[0014] The adhesive layer can facilitate reliable connection between the reinforcement layer and the cover body. When external impact force acts on the reinforcement layer, the reinforcement layer absorbs the impact energy to protect the front camera module, thereby reducing the possibility of damage and failure of the front camera module due to impact.

[0015] In an optional implementation, when the adhesive layer is made of foam, the impact force acts on the reinforcement layer and is transmitted to the foam, the foam is compressed and deformed, and the reinforcement layer absorbs the impact energy, which can effectively reduce the damage to the front camera module caused by the impact force. After the impact force disappears, the foam will stretch, allowing the reinforcement layer to return to its original position.

[0016] In an optional implementation, the adhesive layer is arranged around the edge of the port of the opening. After the reinforcement layer is fixed to the cover body, the reinforcement layer better blocks the opening of the cover body, thereby effectively protecting the front camera module.

[0017] In an optional implementation, the reinforcing layer and the cover body are connected by insert injection molding. The cover body is formed by injection molding, so that the reinforcing layer and the cover body are closely connected to form an integrated structure. When an external impact force acts on the reinforcing layer, the reinforcing layer absorbs the impact energy, thereby reducing the possibility of damage and failure of the front camera module due to the impact.

[0018] In an optional implementation, the reinforcing layer and the cover body are connected by a buckle assembly. A buckle is provided on one of the reinforcing layer and the cover body, and a slot is provided on the other part. The buckle is buckled into the slot, so that the reinforcing layer can be firmly installed on the cover body.

[0019] In an optional implementation, the reinforcing layer and the cover body are connected by a fastener, which passes through the reinforcing layer and the cover body to fix the reinforcing layer on the cover body.

[0020] In an optional implementation, the reinforcement layer is disposed on the outer surface of the cover; or, the reinforcement layer is disposed on the inner surface of the cover; or, the reinforcement layer is located inside the cover. The reinforcement layer can be disposed at different positions of the cover corresponding to the front camera module, and the cover and the reinforcement layer have overlapping parts in the thickness direction, so that the thickness of the overall structure is small, and the front camera module is protected by the reinforcement layer.

[0021] In an optional implementation, the reinforcement layer can be a metal part. When the external impact force acts on the metal reinforcement layer, the reinforcement layer absorbs the impact energy, which can reduce the damage and failure of the front camera module due to the impact. After the impact force disappears, the metal part will return to its original state to prepare for the next external impact.

[0022] In an optional implementation, the cover can be a plastic part, a glass part, or a cover made of other materials. As a structural appearance part of the electronic device, the cover can protect the internal components of the electronic device.

[0023] In an optional implementation, the reinforcement layer can be in a plate or bowl shape, etc., which is easy to shape. After the reinforcement layer and the cover body are combined, the reinforcement layer is at least partially located in the cover body. The reinforcement layer and the cover body are set with appropriate thickness dimensions to make the overall structure thickness dimension smaller.

[0024] In an optional implementation, the reinforcing layer is in a plate shape, and the plate-shaped reinforcing layer and the cover body are arranged in parallel, so that the overall size of the reinforcing layer and the cover body is smaller after being combined.

[0025] In an optional implementation, the reinforcement layer is bowl-shaped, and the bowl-shaped reinforcement layer is buckled at the opening of the cover body. The groove of the bowl-shaped reinforcement layer faces the front camera module, and the end of the front camera module can be embedded in the groove, or the end of the front camera module is not embedded in the groove of the reinforcement layer.

[0026] In an optional implementation, the front camera module and the reinforcement layer are spaced apart, and a certain gap is formed between the back of the front camera module and the reinforcement layer. When the reinforcement layer is impacted, the reinforcement layer absorbs the impact energy, thereby effectively protecting the front camera module.

[0027] In an optional implementation, a projection of the reinforcement layer in the direction of the thickness of the cover body at least partially covers a projection of the front camera module in the direction of the thickness of the cover body.

[0028] The front camera module is effectively protected so that the external impact force acts on the reinforcement layer, reducing the impact damage to the front camera module. When the reinforcement layer completely covers the front camera module, the projection area of ​​the reinforcement layer is greater than or equal to the projection area of ​​the front camera module, and the protection effect on the front camera module is better.

[0029] In an optional implementation, the axis of the front camera module, the thickness direction of the cover body and the thickness direction of the reinforcement layer are parallel, which can make the stacked structure thinner and facilitate the formation of an ultra-thin electronic device.

[0030] In an optional implementation, the cover body has a first positioning groove connected to the opening, the shape of the first positioning groove is matched with the shape of the reinforcement layer, and the reinforcement layer is at least partially located in the first positioning groove.

[0031] When the reinforcing layer is assembled on the cover body, the reinforcing layer can be quickly aligned with the first positioning groove of the cover body and assembled on the cover body, which has high assembly efficiency and is conducive to the assembled reinforcing layer to cover and protect the front camera module.

[0032] In an optional implementation, the outer surface of the reinforcement layer protrudes from the outer surface of the cover; or, the outer surface of the reinforcement layer is flush with the outer surface of the cover; or, the outer surface of the reinforcement layer is lower than the outer surface of the cover. This can effectively protect the front camera module and reduce the damage and failure of the front camera module caused by external impact force.

[0033] In an optional implementation, the front camera module includes a circuit board and a photosensitive element, the photosensitive element is arranged on the circuit board, the side of the circuit board facing away from the photosensitive element is arranged facing the reinforcement layer, and the lens and the photosensitive element are arranged facing each other.

[0034] When working, external light enters the lens, is refracted and converged by the lens, and then projected onto the photosensitive element. The photosensitive element receives the light refracted and converged by the lens to form an image, and converts the light signal into an electrical signal. The photosensitive element is electrically connected to the circuit board, and the signal obtained by the photosensitive element is transmitted to the image signal processor through the circuit board, and converted into a digital image signal by the image signal processor. The reinforcement layer and the circuit board are arranged facing each other, and the reinforcement layer effectively protects the photosensitive element and the circuit board, thereby improving the reliability of the front camera module.

[0035] In an optional implementation, the front camera module further includes a mounting frame, the lens and the circuit board are both arranged on the mounting frame, and the photosensitive element is arranged on the circuit board, so that the front camera module forms an independent module. By fixing the mounting frame on the housing, the front camera module can be conveniently assembled on the housing.

[0036] In an optional implementation, the housing has a second positioning groove connected to the light entrance hole, and the side of the mounting frame facing away from the reinforcement layer is disposed against the bottom surface of the second positioning groove. During assembly, the mounting frame can be quickly aligned and fixed to the second positioning groove, so that the lens is located at the light entrance hole.

[0037] In an optional implementation, the mounting frame is roughly in the shape of a rectangular parallelepiped, the bottom surface of the mounting frame is rectangular, and the second positioning groove is set to be a rectangle that matches the bottom surface of the mounting frame. During assembly, the bottom surface of the mounting frame is aligned with the second positioning groove of the shell, and the mounting frame is quickly positioned and assembled to the shell.

[0038] In an optional implementation, a side of the mounting bracket facing away from the reinforcement layer is directly fixed to the surface of the shell.

[0039] In an optional implementation, a display screen is provided on the side of the housing opposite to the cover body, and the lens of the front camera module is arranged facing the display screen. When the electronic device is used, the display screen can display information such as images and videos. The front camera module can collect external light passing through the display screen to achieve shooting. The display screen and the housing can be connected by bonding or other means.

[0040] In an optional implementation, the display screen includes a display panel. The display panel can be a liquid crystal display, an organic light emitting diode, an active matrix organic light emitting diode or an active matrix organic light emitting diode, a flexible light emitting diode, a sub-millimeter light emitting diode, a micro light emitting diode, a silicon-based organic light emitting diode, a quantum dot light emitting diode, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] See also Figure 1 , an electronic device 10 in the related art, which includes a shell 11, a front camera module 12, a cover 13 and a protective bracket 14. The front camera module 12 is located at the light entrance hole 11a of the shell 11, the protective bracket 14 and the back of the front camera module 12 are connected by foam 15, the edge of the protective bracket 14 and the shell 11 are connected by bonding or screws, the cover 13 is stacked on the shell 11, and the cover 13 and the protective bracket 14 are arranged facing each other. The protective bracket 14 can be a metal plate. A display screen 16 can be set on the side of the shell 11 facing away from the cover 13. Among them, the electronic device 10 can be a mobile phone or a tablet computer, the shell 11 is a middle frame, and the cover 13 is a battery cover.

[0065] The front camera module 12 is located on the front of the electronic device 10 and can be used for user self-portraits or face recognition, etc. When the front camera module 12 is working, external light passes through the display screen 16 and the light entrance hole 11a of the housing 11 and then irradiates the front camera module 12, forming an image on the front camera module 12.

[0066] The back of the electronic device 10 may be equipped with a rear camera module (not shown). Usually, the pixel of the rear camera module is higher than that of the front camera module, and the rear camera module can obtain clearer images or videos. An independent decorative shell (not shown) is set at the position of the cover 13 corresponding to the rear camera module to provide protection or buffer space for the rear camera module.

[0067] The thickness of the front camera module 12 is relatively small, and the front camera module 12 is to be arranged in the electronic device 10. The front camera module 12 cannot be protected by a decorative shell like the rear camera module. A protective bracket 14 is provided at a position of the housing 11 close to the cover 13 as a protective structure for the front camera module 12. When the position of the cover 13 corresponding to the front camera module 12 is impacted, for example, the electronic device 10 falls on an uneven ground so that the position of the cover 13 corresponding to the front camera module 12 is impacted, or a sharp object impacts the position of the cover 13 corresponding to the front camera module 12, the external impact force passes through the cover 13 and the protective bracket 14 in turn, the cover 13 and the protective bracket 14 absorb the impact energy, and the foam 15 is compressed and deformed, thereby reducing the damage and failure of the front camera module 12 due to the impact.

Figure 1 Each part has its own tolerance, and the total thickness is large when accumulated. The end parts require a large assembly tolerance, that is, the electronic device 10 has a large cumulative assembly tolerance in the thickness direction at the front camera module 12.

The cover body 130 is connected to the housing 110, and the cover body 130 has an opening 131 corresponding to the front camera module 120. The reinforcement layer 140 is embedded in the cover body 130 and covers the opening 131, and the reinforcement layer 140 and the front camera module 120 are arranged opposite to each other.

The cover 130 is used as a structural appearance part to protect components such as a battery and a rear camera module. The housing 110 and the cover 130 may be connected by bonding, snapping, etc. Figure 6 The front camera module 120 is a camera located on the front of the electronic device 100. Figure 6 The front camera module 120 is an assembled structure and not an integrated structure. The lens 121 of the front camera module 120 faces in the opposite direction to the outer surface 130a of the cover body 130.

[0073] When the front camera module 120 is fixed to the housing 110, the front camera module 120 can be fixed to the housing 110 by using glue or adhesive; or, the front camera module 120 can be fixed to the housing 110 by using tape, the tape is bonded to the housing 110, and part of the surface of the front camera module 120 is against the housing 110. Alternatively, the front camera module 120 can also be fixed to the housing 110 by using buckles, fasteners, etc.

[0074] The lens 121 of the front camera module 120 is arranged corresponding to the light entrance hole 111, and the lens 121 is at least partially located in the light entrance hole 111.

[0076] In the electronic device 100 provided in the embodiment of the present application, the front camera module 120 is fixed to the housing 110, the lens 121 of the front camera module 120 and the light entrance hole 111 of the housing 110 are arranged correspondingly, the cover 130 is provided with an opening 131 at the position corresponding to the front camera module 120, the reinforcing layer 140 is embedded in the cover 130 and covers the opening 131, the space in the thickness direction of the cover 130 is effectively utilized, there is no protective structure between the front camera module 120 and the cover 130, and the thickness of the electronic device 100 at the front camera module 120 can be made smaller. When the position of the cover 130 corresponding to the front camera module 120 is impacted, the external impact force acts on the reinforcing layer 140, and the reinforcing layer 140 absorbs the impact energy to protect the front camera module 120, which can reduce the situation where the front camera module 120 is damaged and fails due to the impact, and meet the high reliability of the front camera module 120. The electronic device 100 has a simple stacking structure, a simple assembly process, and a small accumulation of assembly tolerances.

Compared with Figure 1 The related art electronic device 10 has six mounting dimensions in the thickness direction, while the electronic device 100 of the present application has fewer mounting dimensions in the thickness direction, and the assembly tolerance accumulation is smaller.

[0078] There are multiple optional implementations for setting the front camera module 120 on the housing 110 .

[0079] The first configuration method of the front camera module 120 is: Figures 6 to 8 , one end 120a of the front camera module 120 facing the reinforcement layer 140 is embedded in the opening 131. In the case where the thickness of the housing 110 is relatively small, the thickness space of the cover 130 is fully utilized, and the one end 120a of the front camera module 120 facing the reinforcement layer 140 is arranged in the opening 131 of the cover 130, so that the front camera module 120 that occupies a certain space can be arranged, so that the thickness of the overall structure can be reduced.

[0080] The second arrangement of the front camera module 120 is that one end 120a of the front camera module 120 facing the reinforcement layer 140 is located in the gap between the cover 130 and the housing 110. A part of the front camera module 120 is extended outside the housing 110 and arranged between the cover 130 and the housing 110, so that the space in the thickness direction is better utilized, and it is convenient to arrange the front camera module 120 that occupies a certain space.

[0081] The third configuration method of the front camera module 120 is: Fig. 9 , Fig.10 , an end 120a of the front camera module 120 facing the reinforcement layer 140 is embedded in the light entrance hole 111. In this way, the front camera module 120 is arranged inside the housing 110, and the end 120a of the front camera module 120 does not extend beyond the housing 110. A hole 131 is opened at a position of the cover 130 corresponding to the front camera module 120 and a reinforcement layer 140 is arranged, and the reinforcement layer 140 provides protection for the front camera module 120.

[0082] There are a variety of optional implementations when the reinforcement layer 140 and the cover body 130 are connected.

[0083] The first method of connecting the reinforcing layer 140 and the cover body 130 is: Figure 6 , Figure 8 , Fig. 9 The reinforcing layer 140 and the cover body 130 are connected by an adhesive layer 150. The adhesive layer 150 can be adhesive, adhesive backing or foam.

[0084] The adhesive layer 150 can facilitate reliable connection between the reinforcement layer 140 and the cover 130. When an external impact force acts on the reinforcement layer 140, the reinforcement layer 140 absorbs the impact energy to protect the front camera module 120, reduce the damage and failure of the front camera module 120 due to the impact, and meet the reliability of the front camera module 120.

[0085] When the adhesive layer 150 is made of foam, the impact force acts on the reinforcement layer 140 and is transmitted to the foam, the foam is compressed and deformed, and the reinforcement layer 140 absorbs the impact energy, which can effectively reduce the damage of the impact force to the front camera module 120. After the impact force disappears, the foam will stretch, so that the reinforcement layer 140 returns to its original position.

[0086] When setting the adhesive layer 150, refer to Figures 4 to 6 The adhesive layer 150 is arranged around the edge of the opening 131. After the reinforcing layer 140 is fixed to the cover 130, the reinforcing layer 140 blocks the opening 131 of the cover 130 well, effectively protecting the front camera module 120, so that the external impact force acts on the reinforcing layer 140 to reduce the end impact on the front camera module 120.

[0087] The second method of connecting the reinforcing layer 140 and the cover body 130 is: Figure 7 , Fig.10 , Fig.11 The reinforcing layer 140 and the cover body 130 are connected by insert injection molding.

[0088] Among them, insert injection molding is to fix the insert in the appropriate position in the mold in advance, and then inject plastic to form it. After the mold is opened, the insert is tightly wrapped in the product by the cooled and solidified plastic.

[0089] In this embodiment, the reinforcing layer 140 is placed as an insert in the injection mold for making the cover body 130, and the cover body 130 is formed by injection molding, so that the reinforcing layer 140 and the cover body 130 are closely connected to form an integrated structure. When an external impact force acts on the reinforcing layer 140, the reinforcing layer 140 absorbs the impact energy, reduces the situation where the front camera module 120 is damaged and fails due to the impact, and meets the reliability of the front camera module 120.

[0090] The third way of connecting the reinforcing layer 140 and the cover body 130 is that the reinforcing layer 140 and the cover body 130 are connected via a buckle assembly, wherein the buckle assembly includes a matching buckle and a slot, and the buckle can be buckled on the slot.

[0091] A buckle is provided on one of the reinforcement layer 140 and the cover body 130 , and a slot is provided on the other part. By buckling the buckle into the slot, the reinforcement layer 140 can be firmly installed on the cover body 130 .

[0092] The fourth method of connecting the reinforcing layer 140 and the cover 130 is that the reinforcing layer 140 and the cover 130 are connected by a fastener. The fastener may be a screw. The fastener passes through the reinforcing layer 140 and the cover 130, so that the reinforcing layer 140 can be fixed on the cover 130.

[0093] There are multiple optional implementations according to the location of the reinforcement layer 140 on the cover 130. Figures 6 to 8 , the reinforcement layer 140 is disposed on the outer surface 130a of the cover body 130; or, refer to Fig. 9 , Fig.10 , the reinforcement layer 140 is disposed on the inner surface 130b of the cover 130; or, refer to Fig.11 , the reinforcement layer 140 is located inside the cover 130. The outer surface 130a of the cover 130 refers to the surface of the cover 130 facing away from the housing 110. The inner surface 130b of the cover 130 refers to the surface of the cover 130 facing the housing 110.

[0094] The reinforcing layer 140 can be arranged at different positions of the cover body 130 corresponding to the front camera module 120. The cover body 130 and the reinforcing layer 140 have overlapping parts in the thickness direction, so that the thickness of the overall structure is smaller, and the front camera module 120 is protected by the reinforcing layer 140.

[0095] When the reinforcing layer 140 is disposed on the outer surface 130a or the inner surface 130b of the cover 130, the reinforcing layer 140 and the cover 130 may be connected by using adhesive, adhesive or foam (eg Figure 8 , Fig. 9 As shown), or by insert injection molding (as shown Figure 7 , Fig.10 When the reinforcing layer 140 is embedded in the cover body 130, the reinforcing layer 140 and the cover body 130 can be formed by insert injection molding (as shown in FIG. Fig.11 shown).

[0096] When setting the reinforcement layer 140, refer to Figure 6 , the reinforcement layer 140 can be a metal part, for example, a structure made of metal such as stainless steel or copper. When the external impact force acts on the metal reinforcement layer 140, the reinforcement layer 140 absorbs the impact energy, which can reduce the damage and failure of the front camera module 120 due to the impact, and meet the reliability of the front camera module 120. After the impact force disappears, the metal part will return to its initial state to prepare for the next external impact. In addition, the reinforcement layer 140 can also be made of other materials.

[0097] When the cover 130 is provided, the cover 130 may be a plastic part, a glass part or a cover of other materials. The cover 130 is a structural appearance part of the electronic device 100 and can protect the internal components of the electronic device 100.

[0098] For example, see Figure 6 The cover 130 is a fiberglass battery cover. The fiberglass battery cover may include a resin layer and a plurality of fiberglass layers stacked on the resin layer. The cover 130 has a low weight and a small thickness. A hole 131 is opened at the position of the battery cover corresponding to the front camera module 120 and a metal reinforcement layer 140 is provided. The metal part has a higher strength than the fiberglass battery cover. When an external impact force acts on the metal part, the metal part absorbs the impact energy and has a small bending deformation, thereby effectively protecting the front camera module 120.

[0099] When the reinforcing layer 140 is set, the reinforcing layer 140 can be in a plate shape or a bowl shape, etc. The reinforcing layers 140 of these shapes are easy to form. After the reinforcing layer 140 and the cover body 130 are combined, the reinforcing layer 140 is at least partially located in the cover body 130. The reinforcing layer 140 and the cover body 130 are set with appropriate thickness dimensions to make the overall structure thickness dimension smaller.

[0100] For example, see Figures 7 to 11 The reinforcing layer 140 is in a plate shape, and the plate-shaped reinforcing layer 140 and the cover body 130 are arranged in parallel, so that the overall size of the reinforcing layer 140 and the cover body 130 is smaller after being combined.

[0101] For example, see Fig.12 , Fig.13 The reinforcing layer 140 is bowl-shaped, and the bowl-shaped reinforcing layer 140 is buckled at the opening 131 of the cover body 130, and the groove 141 of the bowl-shaped reinforcing layer 140 faces the front camera module 120. Fig.12 As shown, the end 120a of the front camera module 120 can be embedded in the groove 141, or, as shown in FIG. Fig.13 As shown, the end 120 a of the front camera module 120 is not embedded in the groove 141 of the reinforcement layer 140 .

[0102] In order to allow the reinforcing layer 140 to have a certain deformation space when it is impacted, in some embodiments, refer to Figure 6 The front camera module 120 and the reinforcement layer 140 are arranged at intervals. A certain gap is formed between the back of the front camera module 120 and the reinforcement layer 140. When the reinforcement layer 140 is impacted, the reinforcement layer 140 absorbs the impact energy, effectively protecting the front camera module 120 and improving reliability.

[0103] In order to enable the reinforcement layer 140 to effectively protect the front camera module 120, in some embodiments, refer to Figure 6 The projection of the reinforcement layer 140 in the thickness direction of the cover body 130 at least partially covers the projection of the front camera module 120 in the thickness direction of the cover body 130 .

[0104] In the thickness direction of the cover 130, the reinforcement layer 140 can cover or partially cover the front camera module 120, thereby effectively protecting the front camera module 120, so that the external impact force acts on the reinforcement layer 140, thereby reducing the impact damage to the front camera module 120. When the reinforcement layer 140 completely covers the front camera module 120, the projection area of ​​the reinforcement layer 140 is greater than or equal to the projection area of ​​the front camera module 120, thereby providing a better protection effect on the front camera module 120.

[0105] In order to reduce the thickness of the stacked structure of the electronic device 100, in some embodiments, refer to Figure 6 , the axis 120 b of the front camera module 120 , the thickness direction of the cover body 130 , and the thickness direction of the reinforcement layer 140 are parallel.

[0106] The axis 120b of the front camera module 120 is the optical axis of the lens 121 of the front camera module 120. The thickness direction of the cover 130 is the direction of the distance between the outer surface 130a and the inner surface 130b of the cover 130. The thickness direction of the reinforcement layer 140 is the direction of the distance between the outer surface 140a and the inner surface 140b of the reinforcement layer 140.

[0107] The axis 120b of the front camera module 120 is arranged perpendicular to the surface of the cover 130, and the reinforcement layer 140 and the cover 130 are arranged in parallel, so that the stacking structure has a smaller thickness, which is conducive to forming an ultra-thin electronic device 100.

[0108] In order to facilitate the positioning and assembly of the reinforcement layer 140, in some embodiments, refer to Figure 3 , Figure 4 The cover body 130 has a first positioning groove 132 connected to the opening 131 . The shape of the first positioning groove 132 matches the shape of the reinforcement layer 140 . The reinforcement layer 140 is at least partially located in the first positioning groove 132 .

[0109] The shape of the first positioning groove 132 and the shape of the reinforcing layer 140 are adapted to each other, which means that the cross-sectional shapes of the two are the same, and the two can be set to a variety of shapes, such as a rounded rectangle, a circle, etc. When the reinforcing layer 140 is assembled to the cover body 130, the reinforcing layer 140 can be quickly aligned with the first positioning groove 132 of the cover body 130 and assembled on the cover body 130, which has a high assembly efficiency and is conducive to the assembled reinforcing layer 140 to cover and protect the front camera module 120.

[0110] Exemplarily, the shape of the first positioning groove 132 and the shape of the reinforcement layer 140 are both set to a rounded rectangle, and the reinforcement layer 140 is aligned with the first positioning groove 132 of the cover body 130. The bottom surface of the first positioning groove 132 and the reinforcement layer 140 can be connected by dispensing glue, back glue or foam, so that the reinforcement layer 140 can be quickly fixed on the cover body 130.

[0111] When the reinforcing layer 140 is disposed on the cover 130, refer to Figure 6 , the outer surface 140a of the reinforcing layer 140 protrudes from the outer surface 130a of the cover body 130; or, refer to Figure 7 , Figure 8 , the outer surface 140a of the reinforcing layer 140 is flush with the outer surface 130a of the cover body 130; or, refer to Figures 9 to 11 , the outer surface 140 a of the reinforcement layer 140 is lower than the outer surface 130 a of the cover body 130 .

[0112] The outer surface 140 a of the reinforcement layer 140 refers to the surface of the reinforcement layer 140 that faces away from the housing 110 . The outer surface 130 a of the cover 130 refers to the surface of the cover 130 that faces away from the housing 110 .

[0113] The above methods can be selected as needed to effectively protect the front camera module 120 and reduce the damage and failure of the front camera module 120 caused by external impact. The shell 110, the front camera module 120 and the cover 130 are all set to conventional thickness dimensions, the reinforcement layer 140 is set to a suitable thickness dimension, and the reinforcement layer 140 is at least partially located in the opening 131 of the cover 130, rather than the reinforcement layer 140 and the cover 130 being stacked, which can make the overall stacked structure thinner.

[0114] When setting the front camera module 120, refer to Fig.14 The front camera module 120 includes a circuit board 122 and a photosensitive element 123. The photosensitive element 123 is arranged on the circuit board 122. The side of the circuit board 122 facing away from the photosensitive element 123 is arranged facing the reinforcement layer 140. The lens 121 and the photosensitive element 123 are arranged facing each other.

[0115] The lens 121 includes one or more optical lenses, which may be convex lenses, concave lenses, or a combination of concave lenses and convex lenses. The photosensitive element 123 may be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor.

[0116] During operation, external light enters the lens 121, is refracted and converged by the lens 121, and is projected onto the photosensitive element 123. The photosensitive element 123 receives the light refracted and converged by the lens 121 to form an image, and converts the optical signal into an electrical signal. The photosensitive element 123 is electrically connected to the circuit board 122, and the signal obtained by the photosensitive element 123 is transmitted to the image signal processor through the circuit board 122, and is converted into a digital image signal by the image signal processor. The reinforcement layer 140 and the circuit board 122 are arranged facing each other, and the reinforcement layer 140 effectively protects the photosensitive element 123 and the circuit board 122, thereby improving the reliability of the front camera module 120.

[0117] In order to facilitate the assembly of the front camera module 120 on the housing 110, in some embodiments, refer to Fig.14 The front camera module 120 further includes a mounting frame 124, on which the lens 121 and the circuit board 122 are both mounted, and the photosensitive element 123 is mounted on the circuit board 122, so that the front camera module 120 forms an independent module. By fixing the mounting frame 124 on the housing 110, the front camera module 120 can be conveniently assembled on the housing 110.

[0118] When assembling the mounting bracket 124 to the housing 110, in some embodiments, refer to Figure 7 , Figure 8, Fig.14 The housing 110 has a second positioning groove 112 connected to the light entrance hole 111, and the side of the mounting frame 124 facing away from the reinforcement layer 140 is disposed against the bottom surface of the second positioning groove 112. During assembly, the mounting frame 124 can be quickly aligned and fixed to the second positioning groove 112, so that the lens 121 is located at the light entrance hole 111. The mounting frame 124 and the housing 110 can be connected by means of adhesive 125, fasteners (such as screws), etc.

[0119] Exemplarily, the mounting frame 124 is roughly in the shape of a rectangular parallelepiped, the bottom surface of the mounting frame 124 is rectangular, and the second positioning groove 112 is set to be a rectangle that matches the bottom surface of the mounting frame 124. During assembly, the bottom surface of the mounting frame 124 is aligned with the second positioning groove 112 of the housing 110, and the mounting frame 124 is quickly positioned and assembled to the housing 110.

[0120] In another embodiment, it is also feasible that the side of the mounting frame 124 facing away from the reinforcement layer 140 is directly fixed to the surface of the housing 110 .

[0121] In order to enable the electronic device 100 to have a display function, in some embodiments, refer to Figure 7 , Figure 8 , Fig.14 A display screen 160 is provided on the side of the housing 110 facing away from the cover body 130 , and a lens 121 of the front camera module 120 is arranged facing the display screen 160 .

[0122] When the electronic device 100 is used, the display screen 160 can display information such as images and videos. The front camera module 120 can collect external light passing through the display screen 160 to achieve shooting. The display screen 160 and the housing 110 can be connected by bonding or other methods.

[0123] When the display screen 160 is provided, the display screen 160 includes a display panel. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED), a flexible light-emitting diode (FLED), a sub-millimeter light-emitting diode (Mini LED), a micro light-emitting diode (microLED), a silicon-based organic light-emitting diode (Micro OLED), a quantum dot light-emitting diode (QLED), etc.

[0124] Finally, it should be noted that the above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application 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.
