The electronic device according to the embodiment of the application includes, but is not limited to, a mobile phone, a notebook computer, a tablet computer, a laptop computer, a personal digital assistant, or a wearable device. The following description will be made with reference to an electronic device as a notebook computer.
Fig. 1 is a schematic structural diagram of an electronic device 100 according to an embodiment of the present application.
As shown in fig. 1, the electronic device 100 may include a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are connected by a rotation shaft to change the opening and closing angle of the first housing 101 and the second housing 102 by the action of the rotation shaft, and to maintain the opening and closing angle as required by the user. For example, when the electronic device 100 is a notebook computer, the first housing 101 may be a display and the second housing 102 may be a keyboard host.
The first housing 101 may include a housing body 10 and a display screen 20, the housing body 10 being a closed cavity, the display screen 20 being disposed on a side of the housing body 10 facing the second housing 102. The top of the housing body 10 includes therein a camera module 30. The camera module 30 is used for realizing a shooting function, and the number of the camera modules 30 can be one or more.
Fig. 2 is a top view of a camera module 30 provided in the prior art.
As shown in fig. 2, the camera module 30 may include: a printed circuit board 301, a lens assembly 302, a first shield case 303, a second shield case 304, and the like. The lens assembly 302 is attached to the printed circuit board 301; the first shielding cover 303 is buckled on the printed circuit board 301, and the first shielding cover 303 is positioned on one side of the lens assembly 302; the second shielding cover 304 is buckled on the printed circuit board 301, and the second shielding cover 304 is positioned on the other side of the lens assembly 302.
The first shield case 303 and the second shield case 304 are both used to shield the influence of external electromagnetic waves on the internal circuit of the electronic device 100 and to shield electromagnetic waves generated inside the electronic device 100 from being radiated to the outside. The first shield 303 and the second shield 304 are fastened to the printed circuit board 301, and the first shield 303 and the second shield 304 can also reinforce the printed circuit board 301.
The first shielding case 303 and the second shielding case 304 are alloy metal cases, and exemplary materials of the first shielding case 303 and the second shielding case 304 may be stainless steel or copper foil, and the thicknesses of the first shielding case 303 and the second shielding case 304 may be about 0.2 mm. In addition, when the first shielding case 303 and the second shielding case 304 are respectively combined with the printed circuit board 301, a welding manner can be adopted to ensure the combination strength.
The lens assembly 302 is located at a middle position of the printed circuit board 301, and the first and second shields 303 and 304 are located at left and right sides of the lens assembly 302, respectively. A space is reserved between the first shielding cover 303 and the lens assembly 302, and a space is reserved between the second shielding cover 304 and the lens assembly 302, so that the phenomenon that any one of the first shielding cover 303 and the second shielding cover 304 collides with the lens assembly 302 to generate interference and influence the operation of the lens assembly 302 is avoided.
Because there is a space between the left and right sides of the lens assembly 302, the printed circuit board 301 is easily broken between the first shielding cover 303 and the lens assembly 302 and the printed circuit board 301 is easily broken between the second shielding cover 304 and the lens assembly 302 during the production and the subsequent assembly process of the camera module 30, which results in the strength of the printed circuit board 301 being reduced and the rigidity of the camera module 30 being affected.
To avoid breakage of the printed circuit board 301 at corresponding locations that leave a space between the lens assembly 302 and the shields (first shield 303 and second shield 304), in one implementation, the glue layer 40 is typically filled at the space between the first shield 303 and the lens assembly 302, and the glue layer 40 is typically filled at the space between the second shield 304 and the lens assembly 302. The strength of the corresponding position of the printed circuit board 301, which is spaced between the lens assembly 302 and the shielding cases (the first shielding case 303 and the second shielding case 304), is reinforced by the adhesive layer 40, thereby reinforcing the rigidity of the camera module 30. However, due to the poor consistency of the adhesive layer 40 and the small rigidity reinforcing effect on the camera module 30, the printed circuit board 301 may still break at the corresponding position where the space is left between the lens assembly 302 and the shielding case (the first shielding case 303 and the second shielding case 304).
Fig. 3 is a side view of a camera module 30 provided in the prior art.
As shown in fig. 3, in another implementation, a reinforcing steel sheet 50 is added to the bottom of the printed circuit board 301, and the reinforcing steel sheet 50 may be attached to the bottom of the printed circuit board 301 by dispensing. The overall strength of the printed circuit board 301 is improved through the reinforced steel sheet 50, the printed circuit board 301 is prevented from being broken at the corresponding position where a gap is reserved between the lens assembly 302 and the shielding cover (the first shielding cover 303 and the second shielding cover 304), and the rigidity of the camera module 30 is ensured.
However, the addition of the reinforcing steel sheet 50 to the bottom of the printed circuit board 301 results in the height H of the camera module 30 30 And (3) increasing. At present, the thinning of the electronic device 100 is one of the development demands of the industry, and the height H of the camera module 30 30 The increase may result in an increase in thickness of the first housing 101 in the electronic device 100, affecting the overall architecture and stacking of the electronic device 100, and preventing the electronic device 100 from being thinned.
The embodiment of the application provides a camera module 30, which does not cause the height H of the camera module 30 30 The increase can also avoid the fracture of the printed circuit board 301 at the corresponding position between the lens assembly 302 and the shielding cover (the first shielding cover 303 and the second shielding cover 304) to improve the strength of the printed circuit board 301 and further improve the shootingRigidity of the head module 30.
In some embodiments, in order to avoid the fracture phenomenon of the printed circuit board 301 in the camera module 30, in the camera module 30 provided in the embodiments of the present application, the strength of the printed circuit board 301 is reinforced by connecting the shielding covers (the first shielding cover 303 and the second shielding cover 304) with the lens assembly 302.
Fig. 4 is a schematic structural diagram of a lens assembly 302 according to an embodiment of the present application.
As shown in fig. 4, in some embodiments, the lens assembly 302 may include a lens unit 3021, a lens mount 3022, and the like, with the lens unit 3021 including a lens and the like, and the lens mount 3022 including a photosensitive chip and the like. The lens unit 3021 is located above the lens mount 3022, and the lens mount 3022 is used to support the lens unit 3021. The surface of the lens assembly 302 is attached with the insert 60, and the insert 60 is used to connect the shield (the first shield 303 and the second shield 304) to the lens assembly 302. Illustratively, the surface of the lens mount 3022 includes an upper surface 30221, a side 30222, and the like.
The insert 60 can avoid direct contact between the shielding case (the first shielding case 303 and the second shielding case 304) and the lens assembly 302, so as to avoid interference phenomenon caused by collision between the shielding case (the first shielding case 303 and the second shielding case 304) and the lens assembly 302, and ensure normal operation of the lens assembly 302. In addition, the embedded part 60 has a shielding function, so that external signals are prevented from entering the lens assembly 302 to influence the normal operation of the photosensitive chip, and the anti-interference capability of the photosensitive chip can be improved through the embedded part 60.
The insert 60 may be made of metal or other materials that can avoid interference between the shielding cases (the first shielding case 303 and the second shielding case 304) and the lens assembly 302.
The insert 60 and the lens mount 3022 may be integrally formed by insert molding, and the lens assembly 302 and the insert 60 may be integrally formed by insert molding, for example. The upper surface 30221 and/or the side surface 30222 of the lens mount 3022 are each injection molded with the insert 60, the insert 60 may cover all area positions of the upper surface 30221 and/or the side surface 30222 of the lens mount 3022, and the insert 60 may also cover part area positions of the upper surface 30221 and/or the side surface 30222 of the lens mount 3022, but at least the portion of the lens mount 3022 that contacts the shield needs to be covered with the insert 60. Fig. 4 shows a state in which the insert 60 covers a part of the upper surface 30221 and/or the side surface 30222 of the lens mount 3022.
Fig. 5 is a schematic structural diagram of a first camera module 30 according to an embodiment of the present application.
As shown in fig. 5, in some embodiments, in the first type of camera module 30, the first shield case 303 may include a first shield top plate 3031, and first shield side plates 3032 respectively located at both sides of the first shield top plate 3031. Illustratively, one first shield side plate 3032 is provided along both sides of the first shield top plate 3031 in the length direction, respectively. Both first shield side plates 3032 are vertically connected to the first shield top plate 3031, and both first shield side plates 3032 are located on the same side with respect to the first shield top plate 3031 such that the first shield cover 303 formed by the first shield top plate 3031 and the first shield side plates 3032 on both sides presents a "concave" structure with one side opened.
The first shielding case 303 is fastened to the printed circuit board 301, that is, two first shielding side plates 3032 in the first shielding case 303 are attached to the printed circuit board 301, and illustratively, two first shielding side plates 3032 are attached to edge positions of the printed circuit board 301 along the width direction. The printed circuit board 301, the first shield top plate 3031 and the two first shield side plates 3032 form a "mouth-shaped" structure, avoiding the first shield case 303 from contacting the wiring in the printed circuit board 301 to affect the electrical performance of the printed circuit board 301.
The structure of the second shield case 304 is the same as that of the first shield case 303, and illustratively, the structure of the second shield case 304 on the side close to the lens assembly 302 is the same as that of the first shield case 303 on the side close to the lens assembly 302. The second shield 304 may include a second shield top plate 3041, and second shield side plates 3042 located on both sides of the second shield top plate 3041, respectively. Illustratively, one second shield side plate 3042 is provided along both sides of the second shield top plate 3041 in the length direction, respectively. Both second shield side plates 3042 are connected perpendicularly to the second shield top plate 3041, the two second shield side plates 3042 being located on the same side with respect to the second shield top plate 3041 such that the second shield 304 formed by the second shield top plate 3041 and the second shield side plates 3042 on both sides assumes a "concave" structure with one side open.
The second shielding cover 304 is fastened to the printed circuit board 301, that is, two second shielding side plates 3042 in the second shielding cover 304 are attached to the printed circuit board 301, and illustratively, two second shielding side plates 3042 are attached to edge positions of the printed circuit board 301 along the width direction. The printed circuit board 301, the second shield top plate 3041, and the two second shield side plates 3042 form a "mouth-shaped" structure that prevents the second shield 304 from contacting wiring in the printed circuit board 301, affecting the electrical performance of the printed circuit board 301.
In the embodiment of the present application, the side of the first shielding cover 303 close to the lens assembly 302 includes a first reinforcing member, and the first reinforcing member is overlapped on one side of the lens assembly 302 through the insert 60 attached to the surface of the lens assembly 302. The first reinforcing member serves to increase the strength of the printed circuit board 301, and to prevent the printed circuit board 301 from being broken at a corresponding position where a space is left between the lens assembly 302 and the first shield case 303.
One side of the second shield 304 adjacent to the lens assembly 302 includes a second reinforcing member that is overlapped on the other side of the lens assembly 302 by the insert 60 that is surface-mounted to the lens assembly 302. The second reinforcing member serves to increase the strength of the printed circuit board 301, and to prevent the printed circuit board 301 from being broken at a corresponding position where a space is left between the lens assembly 302 and the second shield case 304.
Through the combination of the first shielding case 303 with the first reinforcing member and the second shielding case 304 with the second reinforcing member, the overall strength of the printed circuit board 301 can be increased, the occurrence of fracture of the printed circuit board 301 can be avoided, and the rigidity of the camera module 30 can be further improved.

The extending direction is to extend horizontally along the length direction of the first shield top plate 3031 in a direction away from the first shield side plate 3032 such that the first protrusion 3033 is at the same level as the first shield top plate 3031, and the first protrusion 3033 may be parallel to the printed circuit board 301. The first protrusion 3033 protrudes with respect to the first shield side plate 3032 and assumes a floating state, the first protrusion 3033 being not in direct contact with the first shield side plate 3032. The first protrusion 3033 in a suspended state and the printed circuit board 301 below form a first hollow portion (not shown in the figure), and the first hollow portion is used for accommodating one end of the lens base 3022.

As shown in fig. 6, in some embodiments, when the first shield case 303 and the second shield case 304 are mounted on the printed circuit board 301 on which the lens assembly has been mounted in advance, the lens assembly is placed between a first hollowed-out portion formed by the first protrusion 3033 in the first shield case 303 and a second hollowed-out portion formed by the second protrusion 3043 in the second shield case 304, and, illustratively, the lens base 3022 of the lens assembly is placed between the first hollowed-out portion and the second hollowed-out portion.
A first space L exists between the first shield side plate 3032 and one side of the lens mount 3022 1 A second space L exists between the second shielding side plate 3042 and the other side of the lens mount 3022 2 . The first shielding side plate 3032 and the second shielding side plate 3042 are not contacted with the lens base 3022, so that interference phenomenon caused by collision is avoided, and the stability of the lens assembly is affected. Exemplary, first interval L 1 More than or equal to 0.5mm, a second interval L 2 ≥0.5mm。
One end of the lens mount 3022 is located at the bottom of the first protrusion 3033, and the first protrusion 3033 is overlapped on one side of the upper surface 30221 of the lens mount 3022 by the insert 60 attached to the upper surface 30221 of the lens mount 3022.

The first protrusion 3033 may be fixed to the insert 60 attached to the upper surface 30221 of the lens base 3022 by welding to ensure the bonding strength between the first shield case 303 and the insert 60 (the lens assembly 302), thereby avoiding the first space L between the lens assembly 302 and the first shield case 303 left by the printed circuit board 301 1 Fracture at the corresponding location of (c). The second protruding portion 3043 may be fixed to the insert 60 attached to the other side of the upper surface 30221 of the lens base 3022 by welding, so as to ensure the bonding strength between the second protruding portion 3043 and the insert 60, and further avoid the printed circuit board 301 leaving a second space L between the lens assembly 302 and the second shielding case 304 2 Fracture at the corresponding location of (c).
The width of the overlap of the first protrusion 3033 and the lens mount 3022 depends on the length of the first protrusion 3033 and the first interval L 1 And, depending on whether or not the coupling stability of the first protrusion 3033 with the lens mount 3022 can be ensured. Second protrusionThe bonding width of the overlap of the portion 3043 and the lens mount 3022 depends on the length of the second protruding portion 3043 and the second interval L 2 And, depending on whether or not the bonding stability of the second protruding portion 3043 with the lens mount 3022 can be ensured.

In this way, the shielding cases (the first shielding case 303 and the second shielding case 304) on both sides of the lens assembly 302 are connected with the lens assembly 302, so that the printed circuit board 301 is prevented from being broken at the corresponding positions where the space (the first space and the second space) is left between the lens assembly 302 and the shielding cases (the first shielding case 303 and the second shielding case 304), so that the strength of the printed circuit board 301 is improved, and the rigidity of the camera module 30 is improved. In addition, since the outer surface of the lens base 3022 is wrapped with the layer of the insert 60, the insert 60 can avoid direct contact between the shielding cases (the first shielding case 303 and the second shielding case 304) and the lens assembly 302, so as to avoid interference caused by collision; the embedded part 60 can also play a role in shielding to improve the anti-interference capability of the photosensitive chip arranged in the lens base 3022.
