Fig. 1 schematically shows the structure of an electronic device 10. Referring to fig. 1, an electronic device 10 is illustrated as a handheld device having wireless communication capabilities. The handheld device of the wireless communication function may be a mobile phone, for example.
Fig. 2 schematically shows a partially exploded structure of the electronic device 10. Referring to fig. 2, the electronic device 10 of an embodiment of the present application may include a display assembly 20 and a housing assembly 30. The display assembly 20 is connected to the housing assembly 30. The exposed display area on display assembly 20 may be used to present image information to a user.
The electronic device 10 may include a motherboard 40 and electronics 50. The motherboard 40 may be a printed circuit board (printed circuit board, PCB). The electronic device 50 is disposed on the motherboard 40. The electronic device 50 is soldered to the motherboard 40 by a soldering process. The electronic device 50 may include, but is not limited to, a central processing unit (central processing unit, CPU), a smart algorithm chip, and a power management chip (PMIC).
The electronic device 10 may include a camera module 60. The camera module 60 is used for photographing a selected target and forming corresponding image information. The camera module 60 includes a light inlet. External light can enter the camera module 60 through the light inlet. The camera module 60 may be electrically connected with the main board 40, for example, the camera module 60 may be electrically connected with the main board 40 through a flexible circuit board (flexible printed circuit board, FPCB).
The case assembly 30 may include a battery cover 31. The battery cover 31 has a through hole for avoiding the imaging module 60. The through-holes penetrate through the opposite surfaces of the battery cover 31. Along the axial direction of the through hole, the imaging module 60 is disposed corresponding to the through hole. The axial direction of the through-hole may be the extending direction of the through-hole. Illustratively, the cross-sectional shape of the through-hole may be circular, elliptical, or polygonal, as the present application is not limited in this regard.
In the related art, fig. 3 schematically shows the structure of the image capturing module 60. Fig. 4 schematically shows a partially cut-away structure of the camera module 60. The camera module 60 includes a drive motor 70 and a lens assembly 80. For example, the drive motor 70 may be, but is not limited to, a Voice Coil Motor (VCM). The drive motor 70 includes a housing 90, a drive assembly 100, a spring assembly 110, and a carrier 120 (carrier). The carrier 120 is disposed within the housing 90. The elastic member 110 connects the housing 90 and the carrier 120. The carrier 120 is a load bearing structure that is coupled to the spring assembly 110. The drive assembly 100 is disposed in the housing 90. The drive assembly 100 is used to drive the movement of the carrier 120 within the housing 90. The lens assembly 80 and the carrier 120 are manufactured separately from each other, and then the lens assembly 80 is coupled to the carrier 120 by assembly. The lens assembly 80 is removably coupled to the carrier 120. The carrier 120 carries the entire lens assembly 80. The lens assembly 80 includes a lens 130 and a barrel 140 connected to each other. The lens 130 is disposed in the barrel 140. The lens barrel 140 is a carrying structure for carrying the lens 130. The lens 130 and the barrel 140 are manufactured separately. The finished lens 130 and barrel 140 need to be assembled. The barrel 140 of the lens assembly 80 is detachably connected to the carrier 120. For example, an internally threaded bore may be provided on the carrier 120, and the barrel 140 may be externally threaded, such that the barrel 140 is threadably coupled to the carrier 120. After the assembly process of the driving motor 70 is completed, the lens barrel 140 of the lens assembly 80 is screwed to the carrier 120 to assemble the lens assembly 80 and the carrier 120. After the carrier 120 and the lens barrel 140 are assembled, a connection region is formed between the carrier 120 and the lens barrel 140. Glue is required between the carrier 120 and the barrel 140. The glue can connect the carrier 120 and the lens barrel 140, so as to fix the lens barrel 140, improve the connection stability of the carrier 120 and the lens barrel 140, and be favorable for preventing the lens barrel 140 from being separated from the carrier 120 or preventing the lens barrel 140 from loosening. The lens barrel 140 and the carrier 120 are of a split structure, and thus each of the lens barrel 140 and the carrier 120 is required to have mechanical strength satisfying structural design requirements, so that each of the lens barrel 140 and the carrier 120 has a predetermined thickness in a radial direction of the lens barrel 140. Since the lens barrel 140 and the carrier 120 of the lens assembly 80 are stacked on each other in the radial direction of the lens barrel 140, the total thickness of the lens barrel 140 and the carrier 120 after being stacked is relatively large in the radial direction of the lens barrel 140, which results in a relatively large length or width of the camera module 60, that is, a relatively large space occupied by the camera module 60, so that the structural design of the electronic device 10 employing the camera module 60 is limited by the size of the camera module 60.
In addition, during the process of connecting the lens barrel 140 and the carrier 120, there is a problem that the lens barrel 140 and the carrier 120 rub against each other to generate debris. Debris generated between the lens barrel 140 and the carrier 120 may fall onto the image sensor surface, affecting imaging quality. Glue is required to be arranged between the lens barrel 140 and the carrier 120 by adding a glue dispensing process, so that the assembly process and the assembly cost are increased, and the assembly work efficiency is reduced. Since the connection area between the lens barrel 140 and the carrier 120 and the glue is relatively small, and the glue has the problem of cracking caused by falling impact or aging after long-term use, the fixing effect on the lens barrel 140 is lost, so that the lens barrel 140 is at risk of loosening or falling off.
The electronic device 10 of the embodiment of the application comprises a camera module 60. The camera module 60 includes a housing 90, a lens assembly 80, and an elastic assembly 110. The lens assembly 80 includes an outer barrel of unitary construction. The outer barrel of the lens assembly 80 is directly connected to the housing 90 through the elastic assembly 110. The outer cylinder serves as a bearing structure of the lens 130 and also serves as a bearing structure connected with the elastic component 110, so that the thickness of the outer cylinder itself in the radial direction of the outer cylinder can be smaller than the total thickness of the lens barrel 140 and the carrier 120 after superposition in the related art, which is beneficial to reducing the length or width of the camera module 60. In addition, the outer cylinder is of an integrated structure, so that the assembly process and the dispensing process of the lens barrel 140 and the carrier 120 in the related art can be omitted, the problem of scraps generated in the connecting process of the lens barrel 140 and the carrier 120 is avoided, and the technical problem caused by the fact that the connecting is realized by using glue is also avoided.
The following describes an implementation manner of the camera module 60 provided in the embodiment of the present application.
Fig. 5 schematically shows a partially cut-away structure of the camera module 60. Referring to fig. 5, the camera module 60 according to the embodiment of the present application includes an image sensor module 180, a housing 90, a lens module 80, an elastic module 110, and a driving module 100.
The image sensing assembly 180 may include an image sensor 181. The image sensor 181 has a photosensitive surface. The photosensitive surface of the image sensor 181 refers to a surface that receives light. The image sensor 181 may be a sensor that converts an optical signal incident on a photosensitive surface into an electrical signal. For example, the image sensor 181 may be a complementary metal oxide semiconductor (complementary metal oxide semiconductor, CMOS) sensor or a charge coupled device (charge coupled device, CCD).
In some implementations, the image sensing assembly 180 can also include a backplane 182 and a circuit board 183. The image sensor 181 may be disposed on the bottom plate 182. The circuit board 183 may be disposed around the image sensor 181. A circuit board 183 may be connected to the bottom plate 182. The circuit board 183 is used to make electrical connection with the main board 40. Illustratively, the bottom plate 182 may be a steel plate.
The housing 90 includes a side plate 91 and a top plate 92. The housing 90 may be of unitary construction. The side plate 91 is disposed around the image sensor 181. The image sensor 181 is provided inside the side plate 91. The top plate 92 is disposed corresponding to the image sensor 181. The top plate 92 is disposed apart from the image sensor 181. The top plate 92 has a relief hole 92a. The escape hole 92a of the top plate 92 is provided corresponding to the image sensor 181. The housing 90 may provide a mounting base for other structural components while providing protection for internal structural components.
In some examples, the material of the housing 90 may be a metallic material. Illustratively, the material of the housing 90 may be, but is not limited to, steel or an aluminum alloy.
The lens assembly 80 includes an outer barrel 150 and a lens 130. The lens assembly 80 may include a plurality of optic lenses 130. The outer barrel 150 is an integrally formed structure, i.e., the outer barrel 150 itself is a unitary structural member and is not a structural member assembled from a plurality of components. The outer tube 150 is provided with a lens 130. The plurality of lenses 130 are disposed at intervals along the axial direction Z of the outer tube 150. Illustratively, the lens 130 may be adhered to the outer barrel 150 by an adhesive. The longitudinal direction or the width direction of the image pickup module 60 is a direction perpendicular to the axial direction Z of the outer tube 150. Along the axial direction Z of the outer cylinder 150, the lens 130 is disposed corresponding to the image sensor 181. There is a space between the lens 130 and the image sensor 181.
The lens assembly 80 may change the direction of propagation of the light. When the camera module 60 is used for shooting, external light can pass through each lens 130 in the lens assembly 80 and then enter the photosensitive surface of the image sensor 181. The lens assembly 80 has a virtual imaging plane. The imaging surface of the lens assembly 80 may coincide with the photosensitive surface of the image sensor 181.
Fig. 6 schematically shows a partially cut-away structure of the camera module 60. Referring to fig. 5 and 6, the outer tub 150 includes a carrying section 151 and a protruding section 152. The carrier section 151 and the protruding section 152 are distributed successively along the axial direction Z of the outer cylinder 150. The carrier section 151 of the outer barrel 150 is located within the housing 90. The protruding section 152 is provided corresponding to the escape hole 92a of the top plate 92. Along the axial direction Z of the outer cylinder 150, the end of the protruding section 152 away from the carrying section 151 is the light inlet of the camera module 60. In some examples, the protruding section 152 may be threaded through the relief hole 92a, i.e., a portion of the protruding section 152 may be threaded out of the relief hole 92 a. Alternatively, the protruding section 152 may be flush with the outer surface of the top plate 92 facing away from the carrier section 151, i.e., a portion of the protruding section 152 may be located within the relief hole 92a but not pass out of the relief hole 92 a.
Along the axial direction Z of the outer tube 150, the carrier section 151 has a tip end surface 151a facing the top plate 92. The top end surface 151a is disposed around the convex section 152. The top plate 92 shields at least part of the top end surface 151a and the outer edge of the top end surface 151a is located below the top plate 92. The diameter of the outer edge of the top end surface 151a may be larger than the diameter of the escape hole 92a of the top plate 92. When the imaging module 60 is viewed from the outside of the top plate 92, the outer edge of the top end surface 151a is blocked by the top plate 92, and the outer edge of the top end surface 151a cannot be observed through the escape hole 92a in the top plate 92.
In the embodiment of the application, since the outer cylinder 150 is of an integral molding structure, the protruding section 152 and the bearing section 151 are of a closed structure, so that no gap exists in the area of the outer cylinder 150 opposite to the avoiding hole 92a of the top plate 92, and thus external ambient light can only enter the interior of the outer shell 90 through the gap between the bearing section 151 and the top plate 92, so that the amount of light entering the interior of the outer shell 90 can be effectively reduced, and the possibility that stray light propagates to the image sensor 181 to affect the imaging quality can be reduced.
In the related art, since the lens assembly 80 needs to be assembled with the carrier 120, the diameter of the internally threaded hole of the carrier 120 needs to be smaller than the diameter of the escape hole 92a of the top plate 92. The connection region formed by the carrier 120 and the lens barrel 140 is disposed corresponding to the escape hole 92a, that is, the connection region formed by the carrier 120 and the lens barrel 140 can be observed through the escape hole 92 a. In the case where the glue between the carrier 120 and the lens barrel 140 is subjected to drop impact or aged for a long period of time to cause cracks in the glue, there is a possibility that external light propagates to the image sensor 181 through the gap between the carrier 120 and the lens barrel 140, thereby affecting the imaging quality. The camera module 60 according to the embodiment of the present application can effectively solve the above-mentioned technical problems because the outer cylinder 150 is an integrally formed structure.
A space is provided between the top end surface 151a of the carrier section 151 and the top plate 92 in the axial direction Z of the outer tube 150, so that the carrier section 151 does not collide with the top plate 92 in the case where the lens assembly 80 moves in the axial direction Z of the outer tube 150. In some examples, the top end face 151a of the carrier segment 151 may be planar.
In the radial direction of the outer cylinder 150, the carrier section 151 has an outer peripheral surface 151b facing the side plate 91. The outer peripheral surface 151b of the carrier section 151 is disposed directly facing the side plate 91, so that the outer peripheral surface 151b of the carrier section 151 can be directly observed in the case where the housing 90 is removed. The radial direction of the outer cylinder 150 is perpendicular to the axial direction Z of the outer cylinder 150. In the radial direction of the outer cylinder 150, there is a space between the outer peripheral surface 151b of the carrier section 151 and the side plate 91, so that the carrier section 151 is less likely to come into contact with the side plate 91 in the case where the lens assembly 80 is moved.
The elastic member 110 is disposed in the housing 90. The elastic member 110 is coupled to the housing 90. The bearing section 151 of the outer barrel 150 is directly connected with the elastic component 110, that is, no additional switching structural member is required between the bearing section 151 and the elastic component 110, which is beneficial to reducing the number of components. In the related art described above, the lens barrel 140 is indirectly connected to the elastic component 110 through the adapter structure of the carrier 120, and in the embodiment of the present application, the outer barrel 150 with an integrally formed structure is directly connected to the elastic component 110. The spring assembly 110 may provide support to the outer barrel 150 of an integrally formed structure. In the case that the driving assembly 100 drives the lens assembly 80 to move, the elastic assembly 110 may be elastically deformed to provide an elastic force to the lens assembly 80, so that the driving force applied to the lens assembly 80 can be balanced, and the movement process of the lens assembly 80 is ensured to be stable.
In some implementations, referring to fig. 5, the elastic assembly 110 may include a first spring 111 and a second spring 112. The first elastic piece 111 and the second elastic piece 112 are disposed at intervals along the axial direction Z of the outer cylinder 150. The first spring 111 is disposed near the top plate 92, and the second spring 112 is disposed far from the top plate 92. The first elastic piece 111 and the second elastic piece 112 are directly connected with the bearing section 151 of the outer barrel 150. The top end of the bearing segment 151 near the top plate 92 may be connected to the housing 90 through the first elastic sheet 111, and the bottom end of the bearing segment 151 far from the top plate 92 may be connected to the housing 90 through the second elastic sheet 112. The first spring 111 may be connected to the top plate 92 or the side plate 91. The second spring 112 is connected to the side plate 91. In some examples, the first dome 111 may be bonded to the top plate 92 or the side plate 91. The second elastic sheet 112 is adhered to the side plate 91. In some examples, the material of the first dome 111 may be copper or copper alloy. The material of the second spring plate 112 may be copper or copper alloy.
The drive assembly 100 is disposed within the housing 90. The drive assembly 100 is used to drive the lens assembly 80 to move relative to the image sensor 181. The bearing section 151 drives the elastic component 110 to deform. The driving component 100 drives the lens component 80 to realize micro-distance movement, so that the focal length change of the lens component 80 can be controlled to realize a focusing function, and the position change of the lens component 80 can also be controlled to realize an optical anti-shake function (optical image stabilization, OIS). For example, the driving assembly 100 may drive the lens assembly 80 to move along the axial direction Z of the outer cylinder 150 so that the lens assembly 80 may move toward or away from the image sensor 181 to achieve a focusing function.
The camera module 60 in the embodiment of the present application may be a rear camera or a front camera, which is not limited in this aspect of the present application.
The image capturing module 60 according to the embodiment of the present application may be an Auto Focus (AF) module, a Fix Focus (FF) module, a wide-angle image capturing module 60, an ultra-wide-angle image capturing module 60, a vertical-type tele image capturing module 60, or a periscope-type tele image capturing module 60, which is not limited in the embodiment of the present application.
The camera module 60 of the embodiment of the present application includes a housing 90, a lens assembly 80, an elastic assembly 110, and a driving assembly 100. The lens assembly 80 includes an outer barrel 150 and a lens 130. The lens 130 is directly disposed in the outer barrel 150. The outer barrel 150 carries all of the lenses 130. The outer cylinder 150 is an integrally formed structure. The outer barrel 150 includes a carrier section 151 and a protruding section 152. The carrier section 151 is directly connected to the spring assembly 110. The driving assembly 100 is used for driving the lens assembly 80 to move. Since the outer cylinder 150 is an integrally formed structure, the outer cylinder 150 itself may have mechanical strength satisfying structural design requirements with a relatively small thickness in the radial direction of the outer cylinder 150. In the related art, the lens barrel 140 and the carrier 120 are required to each have mechanical strength satisfying structural design requirements, so that the total thickness of the lens barrel 140 and the carrier 120 after stacking is relatively large in the radial direction of the lens barrel 140. Compared to the related art, the thickness of the outer barrel 150 of the embodiment of the present application may be smaller than the total thickness of the lens barrel 140 and the carrier 120 in the related art, so as to facilitate reducing the size of the camera module 60, for example, reducing the length or width of the camera module 60, and reducing the possibility that the structural design of the electronic device 10 is limited by the size of the camera module 60. In addition, the outer cylinder 150 of the embodiment of the present application is an integrally formed structure, and the assembling process and dispensing process of the lens barrel 140 and the carrier 120 in the related art can be omitted.
In addition, in the related art, if the objective of reducing the total thickness of the lens barrel 140 and the carrier 120 after stacking is achieved by reducing the thickness of the lens barrel 140, the mechanical strength of the lens barrel 140 with reduced thickness is also relatively reduced, so that the cured glue between the lens barrel 140 and the carrier 120 will exert a tensile force or a compressive force on the lens barrel 140, resulting in local deformation of the lens barrel 140, and further resulting in deviation of the lens 130 at the corresponding position of the lens barrel 140, which affects the imaging quality of the imaging module 60. The outer cylinder 150 of the embodiment of the present application is an integrally formed structure, so that the above technical problems can be effectively solved.
In some realizable modes, the outer cylinder 150 is of an injection molding integrated structure, that is, the outer cylinder 150 can be integrally molded by adopting an injection molding process, so that the outer cylinder 150 is convenient to process and manufacture, and the processing procedure and the assembling procedure of the camera module 60 are facilitated to be simplified. In some examples, the material of the outer cylinder 150 may be, but not limited to, polycarbonate (PC) or liquid crystal polymer material (liquid crystal polymer, LCP), thereby helping to ensure the quality of the molded product. In the injection molding process, a material to be molded is injected into an injection mold for molding the outer tub 150. The outer cylinder 150 of the integrally formed structure itself has a relatively large structural strength, so that the outer cylinder 150 can have a relatively small wall thickness while satisfying the mechanical strength requirement.
In some implementations, referring to fig. 6, the outer barrel 150 has a central receiving bore 150a. The central receiving hole 150a penetrates the carrying section 151 and the protruding section 152. The lens 130 is disposed in the central receiving hole 150a. The central receiving hole 150a may be a stepped hole so that lenses 130 of different diameters are disposed within the central receiving hole 150a. The central receiving bore 150a includes a first bore section on the carrier section 151 and a second bore section on the protruding section 152. Part of the first hole section is located below the top plate 92.
In the related art, since the lens barrel 140 of the lens assembly 80 is required to be assembled with the carrier 120, the diameter of the female screw hole of the carrier 120 is smaller than the diameter of the escape hole 92a of the top plate 92, so that the diameter of the central hole of the lens barrel 140 for mounting the lens 130 is also smaller than the diameter of the escape hole 92a, so that the central hole of the lens barrel 140 cannot be located under the top plate 92.
The outer cylinder 150 of the embodiment of the present application is an integrally formed structure. The housing 90 may be assembled with the outer cylinder 150 by sleeving, i.e. the relief hole 92a in the top plate 92 of the housing 90 is sleeved on the protruding section 152 of the outer cylinder 150. Therefore, the avoidance hole 92a on the top plate 92 only needs to avoid the protruding section 152, and the distance between the side plate 91 of the housing 90 and the outer cylinder 150 can be kept relatively small, so that the size of the housing 90 can be designed relatively small, thereby being beneficial to reducing the length or width of the image capturing module 60. Since the relief hole 92a may be designed in a relatively small size, the diameter of the first hole section of the carrier section 151 may be larger than the diameter of the relief hole 92a, such that a portion of the first hole section larger than the relief hole 92a is located below the top plate 92.
In some implementations, fig. 7 schematically shows a partial cross-sectional structure of the camera module 60. Referring to fig. 7, the lens assembly 80 further includes an adapter sleeve 160. The adapter sleeve 160 is detachably connected to the protruding section 152 of the outer sleeve 150. Along the axial direction Z of the outer cylinder 150, the adapter cylinder 160 is positioned on the side of the protruding section 152 facing away from the carrying section 151. The lens 130 is disposed in the adapter tube 160.
After the outer barrel 150 is assembled with the housing 90, the adapter barrel 160 is assembled with the protruding section 152. Alternatively, the adapter tube 160 is assembled with the protruding section 152, and then the top plate 92 of the housing 90 is sleeved on the adapter tube 160 and the protruding section 152. Therefore, different assembly modes can be selected according to the design of the optical sensitivity of the lens 130, and the assembly mode is optimized, so that the optical performance yield of the camera module 60 is improved, and the imaging quality is improved.
When the outer tube 150 itself has a length larger than the diameter of the outer tube 150, the lens 130 is relatively easily displaced due to the limitation of the longer length of the outer tube 150 when the lens 130 is disposed in the outer tube 150. Since the optical sensitivity of the lens 130 is high, a small offset of the lens 130 affects the imaging quality. In the embodiment of the application, by adopting the two-section structure of the outer barrel 150 and the adapter barrel 160, the lengths of the outer barrel 150 and the adapter barrel 160 are relatively short, which is beneficial to ensuring high installation precision of the lens 130 in the outer barrel 150 and high installation precision of the lens 130 in the adapter barrel 160, thereby ensuring good imaging quality of the camera module 60.
In some examples, the pod 160 is an integrally formed structure. For example, the adapter sleeve 160 may be of unitary injection molded construction. In some examples, the material of the pod 160 may be, but is not limited to, polycarbonate (PC) or liquid crystal polymer material (liquid crystal polymer, LCP).
In some examples, since the outer cylinder 150 and the adapter cylinder 160 are two-stage assembled structures, the maximum diameter of the adapter cylinder 160 may be designed to be larger than the diameter of the avoidance hole 92a on the top plate 92, so that the structure of the adapter cylinder 160 is flexibly designed according to the design requirement of the camera module 60.
In some examples, the pod 160 is bonded to the boss 152. Along the axial direction Z of the outer barrel 150, the adapter barrel 160 has a first end face 160a facing the protruding section 152, and the protruding section 152 has a second end face 152a facing the adapter barrel 160. Glue may be pre-applied to at least one of the first end face 160a of the adapter sleeve 160 and the second end face 152a of the protruding section 152, and then the protruding section 152 and the adapter sleeve 160 may be assembled. After the glue is cured, the protruding section 152 is connected to the adapter tube 160. By bonding, it is advantageous to ensure that a relatively small thickness bond layer is formed between the adapter sleeve 160 and the protruding section 152, thereby facilitating control of the dimension of the lens assembly 80 in the axial direction Z of the outer sleeve 150.
In some examples, fig. 8 schematically shows a partial cross-sectional structure of the camera module 60. Fig. 9 schematically shows a partially cross-sectional structure of the image pickup module 60 in a partially exploded state. Referring to fig. 8 and 9, the adapter tube 160 has a first positioning portion 161. The protruding section 152 has a second positioning portion 152b. The first positioning portion 161 and the second positioning portion 152b are abutted in the axial direction Z of the outer tube 150. Because the optical sensitivity of the lens 130 is high, the accuracy of the butt joint between the adapter tube 160 and the protruding section 152 can affect the imaging quality of the camera module 60. In the process of assembling the adapter tube 160 and the protruding section 152, the first positioning part 161 and the second positioning part 152b are used for positioning, so that the position alignment precision of the adapter tube 160 and the protruding section 152 is improved, and the possibility of offset of the lens 130 in the adapter tube 160 caused by slight inclination of the adapter tube 160 is reduced. Illustratively, the first and second positioning portions 161 and 152b may be adhered to each other. The abutting area of the first positioning portion 161 and the second positioning portion 152b may be provided with adhesive.
In some examples, the adapter sleeve 160 has a first end face 160a facing the protruding section 152 along the axial direction Z of the outer sleeve 150. The first positioning portion 161 is provided on the first end surface 160a. Along the axial direction Z of the outer cylinder 150, the protruding section 152 has a second end surface 152a facing the adapter cylinder 160, and the second positioning portion 152b is disposed on the second end surface 152a. In the case where the first positioning portion 161 and the second positioning portion 152b are abutted, the first positioning portion 161 and the second positioning portion 152b do not occupy more space in the radial direction of the outer cylinder 150, so that in the case where the image capturing module 60 is applied to the electronic apparatus 10, it is possible to advantageously save installation space for other structural members in the electronic apparatus 10.
Illustratively, one of the first and second positioning portions 161 and 152b is a protrusion and the other is a recess. For example, the first positioning portion 161 is a protrusion, and the second positioning portion 152b is a groove. After the first positioning part 161 and the second positioning part 152b are butted along the axial direction Z of the outer cylinder 150, the first positioning part 161 and the second positioning part 152b are mutually spliced, so that the first positioning part 161 and the second positioning part 152b can reuse space in the axial direction Z of the outer cylinder 150, and therefore, the first positioning part 161 and the second positioning part 152b do not occupy more space along the axial direction Z of the outer cylinder 150, which is beneficial to controlling the size of the lens assembly 80 in the axial direction Z of the outer cylinder 150.
For example, referring to fig. 9, in the adapter cylinder 160, the first positioning part 161 may be provided at an outer edge region of the first end surface 160a of the adapter cylinder 160. In the outer cylinder 150, the second positioning portion 152b may be disposed at an outer edge region of the second end surface 152a of the protruding section 152. For example, the first positioning portion 161 may be a ring-shaped protrusion. The second positioning portion 152b may be an annular groove. During the bonding process of the first end surface 160a of the adapter tube 160 and the second end of the protruding section 152, the first positioning portion 161 can block the radial flow of the adhesive along the outer tube 150, so that the possibility that the adhesive is extruded to overflow from the joint of the adapter tube 160 and the outer tube 150 is reduced.
Illustratively, fig. 10 schematically shows a partial cross-sectional structure of the camera module 60. Fig. 11 schematically shows a partially cross-sectional structure of the image pickup module 60 in a partially exploded state. Referring to fig. 10 and 11, in the adapter cylinder 160, a first positioning portion 161 may be provided at a middle region of a first end surface 160a of the adapter cylinder 160. In the outer cylinder 150, the second positioning portion 152b may be disposed at a middle region of the second end surface 152a of the protruding section 152. For example, the first positioning portion 161 may be a ring-shaped protrusion. The second positioning portion 152b may be an annular groove.
Before the adapter tube 160 and the protruding section 152 are butted, an adhesive may be coated on at least one of the first positioning portion 161 and the second positioning portion 152 b. In the process of abutting the adapter tube 160 and the protruding section 152, the first positioning portion 161 and the second positioning portion 152b are mutually inserted, and the first positioning portion 161 and the second positioning portion 152b can co-squeeze the adhesive, so that the adhesive can overflow and flow to the first end face 160a and the second end face 152 a. By controlling the amount of adhesive applied to the first positioning portion 161 or the second positioning portion 152b, the distance that the adhesive flows toward the first end surface 160a and the second end surface 152a can be controlled, so as to facilitate reducing the possibility that the adhesive overflows from the connection between the adapter tube 160 and the outer tube 150.
Illustratively, the cross-section of the first locating portion 161 and the cross-section of the second locating portion 152b may each be trapezoidal. In the process of mutually inserting the first positioning portion 161 and the second positioning portion 152b, the first positioning portion 161 and the second positioning portion 152b can realize self-positioning, so as to ensure the position precision of the adaptor sleeve 160 and the protruding section 152 after being abutted.
In some examples, fig. 12 schematically shows a partial cross-sectional structure of the electronic device 10. Referring to fig. 10 and 12, the adapter sleeve 160 has a third end face 160b facing away from the protruding section 152 and an inclined face 160c. The third end face 160b is connected to the inclined face 160c. The inclined surface 160c is disposed facing the lens 130. The third end face 160b is disposed around the inclined face 160c. The housing assembly 30 also includes a trim piece 32. The decoration 32 is connected to the battery cover 31. The garnish 32 includes a garnish ring 321 and a cover plate 322. The cover plate 322 is disposed on the bezel 321. The cover plate 322 includes an annular light shielding region 322a and a centrally located light transmitting region 322b. The light shielding region 322a on the cover plate 322 may be formed using a silk screen process. In the case that the camera module 60 is disposed in the electronic device 10, the third end surface 160b of the adapter tube 160 may be disposed corresponding to the light shielding region 322a of the cover 322, and the lens 130 in the adapter tube 160 is disposed corresponding to the light transmitting region 322b. The inclined surface 160c of the adapter tube 160 is disposed to face the light-transmitting region 322b so that the inclined surface 160c can be seen when viewed from the outside of the cover plate 322.
Because the adapter tube 160 can be manufactured separately, the inclined surface 160c of the adapter tube 160 can be designed to be relatively large in size, so that when the electronic device 10 is assembled eccentrically and slightly inclined, the whole camera module 60 can still only observe the inclined surface 160c and the third end surface 160b when the cover plate 322 is observed at the outer side, thereby being beneficial to ensuring that the camera module 60 has good appearance aesthetic degree, reducing the assembly precision requirement between the camera module 60 and the decoration 32 and reducing the assembly difficulty.
In some examples, third end face 160b may be planar.
In some implementations, fig. 13 schematically shows a partial cross-sectional structure of the camera module 60. Referring to fig. 13, the outer tub 150 further includes a weight structure 150b. At least one of the carrier section 151 and the protruding section 152 is provided with a weight structure 150b. According to the different design requirements of the camera module 60, the weight of the outer barrel 150 also has different design requirements so as to match the driving performance of the driving assembly 100 on the outer barrel 150, and ensure that the driving assembly 100 has good driving precision. Because the outer cylinder 150 is an integrally formed structure, the weight of the outer cylinder 150 can be relatively easily changed by providing the corresponding weight structure 150b on the outer cylinder 150, so that the outer cylinder 150 can be relatively easily matched with different requirements of the driving assembly 100, and the accuracy and the linearity of the automatic focusing process of the driving assembly 100 driving the lens assembly 80 can be ensured.
In some examples, referring to fig. 13, the weight structure 150b may be a groove or cut-out to reduce the weight of the outer barrel 150 accordingly, depending on design requirements.
In some examples, fig. 14 schematically shows a partial cross-sectional structure of the camera module 60. Referring to fig. 14, the weight structure 150b may be a protrusion to increase the weight of the outer tub 150 according to design requirements.
In some implementations, referring to fig. 14, the lens assembly 80 further includes a spacer ring 170. A spacer ring 170 is disposed between at least a portion of the number of lenses 130. In some examples, spacer 170 may be an insulating structural member. For example, the material of spacer 170 may be plastic. The spacer 170 is disposed corresponding to the edge region of the lens 130. Along the axial direction Z of the outer cylinder 150, the spacer ring 170 is used to carry the lenses 130 on both sides, thereby ensuring the stable position of the lenses 130. The spacer 170 may isolate adjacent lenses 130 from contact.
In some implementations, referring to fig. 14, the camera module 60 further includes an annular mount 190 and a filter 200. The annular mounting seat 190 is located on a side of the carrier section 151 facing away from the protruding section 152. The optical filter 200 is disposed on the annular mount 190. The optical filter 200 is disposed between the lens 130 and the image sensor 181 along the axial direction Z of the outer cylinder 150. External light may enter the lens assembly 80 from the light entrance portion of the lens assembly 80. After converging through the lens 130 in the lens assembly 80, the image is filtered through the filter 200 and finally transmitted to the image sensor 181 to form a corresponding image on the image sensor 181.
Along the axial direction Z of the outer cylinder 150, there is a space between the lens assembly 80 and the filter 200. As the drive assembly 100 drives the lens assembly 80 to move relative to the housing 90, the lens assembly 80 moves relative to the filter 200 to move closer to or farther from the filter 200.
In some examples, the filter 200 may be an infrared filter. The optical filter 200 can play a role of infrared cut-off and filtering, so as to ensure that the imaging color of the image sensor 181 accords with the resolution rule of human eyes. Illustratively, the optical filter 200 may be provided with an anti-reflection film to improve light transmittance and ensure the photosensitive effect of the image sensor 181.
In some examples, the annular mount 190 and the filter 200 are bonded to each other.
In some examples, the side plate 91 of the housing 90 is connected to an annular mount 190. For example, the side plate 91 may be bonded to the annular mount 190.
In some examples, the circuit board 183 of the image sensing assembly 180 is located below the annular mount 190.
In some implementations, fig. 15 schematically shows a partial cross-sectional structure of the camera module 60. Referring to fig. 15, the camera module 60 further includes a filter 200. The optical filter 200 is disposed on the carrying section 151 of the outer barrel 150. The optical filter 200 is disposed between the lens 130 and the image sensor 181 along the axial direction Z of the outer cylinder 150.
When the driving assembly 100 drives the lens assembly 80 to move relative to the housing 90, the lens assembly 80 moves in synchronization with the optical filter 200 so that the optical filter 200 can move toward or away from the image sensor 181. Because the optical filter 200 is disposed in the outer cylinder 150, the optical filter 200 and the lens 130 can jointly utilize the space in the outer cylinder 150, so that the optical filter 200 does not occupy more space along the axial direction Z of the outer cylinder 150, which is beneficial to reducing the size of the image pickup module 60 in the axial direction Z of the outer cylinder 150. The height direction of the image pickup module 60 is the same as the axial direction Z of the outer cylinder 150.
In some examples, the side plates 91 of the housing 90 may be connected to the bottom plate 182 of the image sensing assembly 180.
In some implementations, referring to fig. 15, the drive assembly 100 includes a conductive coil 101 and a magnet 102. At least a portion of the conductive coil 101 is embedded in the carrier section 151 of the outer barrel 150. The portion of the conductive coil 101 embedded in the carrier section 151 is in an invisible state. The magnet 102 may be provided to the side plate 91. The magnet 102 is used to generate a magnetic field. The conductive coil 101 in the magnetic field, when energized, is used to drive the lens assembly 80 to move relative to the image sensor 181.
Compared with the way that the conductive coil 101 is directly wound on the outer cylinder 150, the connection way of the conductive coil 101 and the outer cylinder 150 in the embodiment of the application can reuse space in the radial direction of the outer cylinder 150, thereby being beneficial to reducing the space occupied by the conductive coil 101 in the radial direction of the outer cylinder 150, further reducing the space between the outer cylinder 150 and the side plate 91 of the housing 90, and further reducing the length or width of the image pickup module 60.
In some examples, the conductive coil 101 is entirely embedded in the carrier section 151 of the outer barrel 150, i.e., the conductive coil 101 is entirely in an invisible state.
In some examples, the conductive coil 101 and the outer barrel 150 may be formed as a unitary structure by an injection molding process. For example, the conductive coil 101 may be fixed in an injection mold in advance, and then the material for forming the outer cylinder 150 is injected into the mold, eventually making the conductive coil 101 and the outer cylinder 150 into a unitary structure.
In the related art, in the assembly mode in which the conductive coil 101 is wound around the outer cylinder 150, there is impact or friction between the conductive coil 101 and the outer cylinder 150, thereby causing debris to be generated during the assembly process. The generated debris may fall to the surface of the image sensor 181, affecting the imaging quality. In the embodiment of the application, the conductive coil 101 does not need to be assembled with the outer cylinder 150, so that scraps can be avoided between the conductive coil 101 and the outer cylinder 150.
In an embodiment of the present application, the image capturing module 60 shown in fig. 14 may be a wide-angle image capturing module. The camera module 60 shown in fig. 15 may be a group camera module. Fig. 16 schematically shows a partially cut-away structure of the image pickup module 60. The camera module 60 shown in fig. 16 may be an ultra-wide angle camera module. Fig. 17 schematically shows a partially cut-away structure of the image pickup module 60. The camera module 60 shown in fig. 17 may be a vertical tele camera module. Fig. 18 schematically shows a partially cut-away structure of the camera module 60. The camera module 60 shown in fig. 18 may be a periscope type tele camera module.
