The mobile phone is the electronic equipment provided with the cellular communication module.

Referring to fig. 1, fig. 1 is a schematic perspective exploded view of an electronic device according to an embodiment of the present application. The electronic device 1000 may be a portable device such as a mobile phone, a tablet computer, a notebook computer, a wearable device, and the like. The electronic device 1000 of the present embodiment is illustrated by taking a mobile phone as an example.

The electronic device 1000 may include a camera mechanism 100, a display screen 200, and a housing 300. The display 200 and the housing 300 are connected and enclosed to form a receiving space 1001. The accommodating space 1001 may be used for providing structural components such as the camera mechanism 100, a motherboard, a battery, and the like, so that the electronic device 1000 can implement corresponding functions. The display screen 200, the camera mechanism 100 and other structural members can be electrically connected with the main board, the battery and the like through circuit boards (Flexible Printed Circuit, FPC) respectively, so that the display screen 200, the camera mechanism 100 and the like can obtain electric energy supply of the battery and execute corresponding instructions under the control of the main board. Based on this, the camera mechanism 100 may be located at one side of the display screen 200 and configured to collect light (hereinafter, referred to as external light) outside the electronic device 1000.

It should be noted that: taking the electronic device 1000 such as a mobile phone as an example, the camera mechanism 100 may be used to implement front-end imaging of the electronic device 1000, and may also be used to implement rear-end imaging of the electronic device 1000. That is, the camera mechanism 100 may be either front-mounted or rear-mounted. The front camera may be that the camera mechanism 100 receives light to image on a side close to the display screen 200, and the rear camera may be that the camera mechanism 100 receives light to image on a side away from the display screen 200.

The display screen 200 may be used to provide an image display function for the electronic device 1000, and when a user uses the photographing function of the electronic device 1000, the display screen 200 may present an imaging screen of the camera mechanism 100 for the user to observe and operate.

The surface of the transparent cover plate can have the characteristics of smoothness so as to facilitate touch operations such as clicking, sliding, pressing and the like. The transparent cover plate may be made of rigid material such as glass, or flexible material such as Polyimide (PI) and colorless Polyimide (Colorless Polyimide, CPI). The touch panel is disposed between the transparent cover plate and the display panel, and is configured to respond to a touch operation of a user, and convert the corresponding touch operation into an electrical signal to be transmitted to the processor of the electronic device 1000, so that the electronic device 1000 can respond to the touch operation of the user. The display panel is mainly used for displaying pictures and can be used as an interactive interface for indicating a user to perform the touch operation on the transparent cover plate. The display panel may employ an OLED (Organic Light-Emitting Diode) or an LCD (Liquid Crystal Display ) to realize an image display function of the electronic device 1000. In this embodiment, the transparent cover plate, the touch panel and the display panel may be bonded together by using an adhesive such as OCA (Optically Clear Adhesive, optical adhesive), PSA (Pressure Sensitive Adhesive ) or the like.

The housing 300 may be used for mounting various electronic devices required by the electronic apparatus 1000, and the housing 300 and the display screen 200 may together enclose a receiving space 1001. The accommodating space 1001 can be used for installing electronic devices such as an optical sensor, so as to realize functions such as fingerprint unlocking, automatic screen extinction, brightness self-adjustment and the like. The accommodating space 1001 may also be used for mounting electronic devices such as a microphone, a speaker, a flash, a circuit board, and a battery, so as to implement functions such as voice communication, audio playback, and illumination.

It will be appreciated that: all directional indications (such as up, down, left, right, front, back … …) in embodiments of the present application are merely used to explain the relative positional relationship, movement, etc. between the components in a particular gesture (as shown in the drawings), and if the particular gesture changes, the directional indication changes accordingly.

Referring to fig. 2, a schematic cross-sectional view of a camera mechanism in the related art of fig. 2 is shown. In the related art, the camera mechanism 500 includes a housing 501, a slide assembly 502, and a lens group 503. The housing 501 includes a receiving cavity 5011, the sliding component 502 is received in the receiving cavity 5011, and the lens group 503 is fixed on the sliding component 502 and can be driven by the sliding component 502 to move. Specifically, the sliding assembly 502 includes a first slide plate 5021, a second slide plate 5022, and a third slide plate 5023 that are stacked, the first slide plate 5021 abuts against the bottom wall of the accommodating cavity 5011, and the third slide plate 5023 is fixedly connected with the lens group 503. The surface of the first slide plate 5021 facing the second slide plate 5022 is provided with a first sliding groove 50211 along a first direction, the surface of the second slide plate 5022 facing the first slide plate 5021 is provided with a second sliding groove 50221 corresponding to the first sliding groove 50211, and the first balls 504 are accommodated in the corresponding first sliding groove 50211 and second sliding groove 50221, so that the second slide plate 5022 can move along the first direction relative to the first slide plate 5021. The surface of the second slide plate 5022 facing the third slide plate 5023 is provided with a third slide groove 50222 along the second direction, the surface of the third slide plate 5023 facing the second slide plate 5022 is provided with a fourth slide groove 50231 corresponding to the third slide groove 50222, and the second balls 505 are accommodated in the corresponding third slide groove 50222 and fourth slide groove 50231, so that the third slide plate 5023 can move along the second direction relative to the second slide plate 5022. In the above manner, the lens group 503 can be moved in the first direction and/or the second direction, thereby realizing movement of the lens group 503 in each direction in the accommodation cavity 5011.

However, the sliding component 502 in the related art has many components and complex structure, which is disadvantageous for miniaturization of the camera mechanism 500, and in view of this, it is necessary to provide a new camera mechanism 500 to simplify the structure of the camera mechanism 500 and reduce the size of the camera mechanism 500.

Referring to fig. 3 and 4, fig. 3 is a schematic perspective view of a camera mechanism in the electronic device shown in fig. 1, and fig. 4 is an exploded schematic view of the camera mechanism shown in fig. 3. The camera mechanism 100 provided by embodiments of the present application may include, but is not limited to, a housing assembly 10, a lens group 20, and at least two anti-shake assemblies 30. The housing assembly 10 may have a sliding cavity 120, and the lens assembly 20 is accommodated in the sliding cavity 120 and is movable in the sliding cavity 120. Each anti-shake assembly 30 includes an anti-shake coil 31 and an anti-shake magnet 32, one of the anti-shake coil 31 and the anti-shake magnet 32 is fixed on the lens assembly 20, and the other is fixed on the housing assembly 10, and the anti-shake coil 31 can cooperate with the anti-shake magnet 32 for driving the lens assembly 20 to move in the sliding cavity 120. The at least two anti-shake components 30 are disposed along a first direction and a second direction, respectively, and are used for moving the lens group 20 in the sliding cavity 120 along the first direction and/or the second direction, so as to realize optical anti-shake of the camera mechanism 100.

Compared to the prior art, the camera mechanism 100 provided in the embodiment of the present application eliminates the sliding component 502, so that the lens group 20 directly moves in the sliding cavity 120 of the housing component 10 along the first direction and/or the second direction, thereby realizing optical anti-shake of the camera mechanism 100. In this way, the structure of the camera mechanism 100 is simpler, and the size of the camera mechanism 100 can be made smaller.

It should be noted that the terms "first," "second," and "third" are used herein for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In this embodiment, the first direction is perpendicular to the second direction, wherein the first direction is parallel to the bottom wall of the sliding chamber 120, and the second direction is parallel to the bottom wall of the sliding chamber 120. Specifically, the lens group 20 may move in the first direction in the sliding cavity 120, may move in the second direction in the sliding cavity 120, and may also move in both the first direction and the second direction, thereby enabling the lens group 20 to move in all directions on the bottom wall of the sliding cavity 120. In other embodiments, the first direction may also be at an acute angle to a second direction, where the first direction is parallel to the bottom wall of the sliding cavity 120 and the second direction is parallel to the bottom wall of the sliding cavity 120.

In this embodiment, the housing assembly 10 may include an outer housing 11 and an inner housing 12. The outer housing 11 may include a receiving cavity 110, and the inner housing 12 is received in the receiving cavity 110 and is rotatable relative to the outer housing 11. Specifically, the camera mechanism 100 may further include a focusing assembly 40, where the focusing assembly 40 may include one of a focusing coil 41 and a focusing magnet 42 disposed on the inner housing 12, and the other one is disposed on the baffle 1212, and the focusing coil 41 and the focusing magnet 42 cooperate with each other to drive the lens group 20 to rotate in the sliding cavity 120, so as to implement focusing anti-shake of the camera mechanism 100.

The inner housing 12 has a sliding cavity 120, and the lens group 20 is accommodated in the sliding cavity 120 and is capable of sliding relative to a bottom wall of the sliding cavity 120. As can be appreciated, the lens group 20 moves in the sliding chamber 120 and can move in all directions on the bottom wall of the sliding chamber 120 to realize the OIS function of the lens group 20; the inner housing 12 is rotatable relative to the outer housing 11 to achieve the AF function of the camera mechanism 100.

Referring to fig. 5 to 7, fig. 5 is an exploded view of an outer housing in the camera mechanism shown in fig. 4, fig. 6 is a perspective view of a first housing in the outer housing shown in fig. 5, and fig. 7 is a partially enlarged view of a region a shown in fig. 6. Specifically, the outer housing 11 may include a first housing 111 and a second housing 112 that are connected in a covering manner. The first housing 111 includes a bottom plate 1111 and a first side plate 1112 fixed on a side surface of the bottom plate 1111, and the bottom plate 1111 and the first side plate 1112 enclose a housing cavity 110. The second housing 112 includes a top plate 1121 and a second side plate 1122 extending from an edge of the top plate 1121, where the second side plate 1122 wraps an outer surface of the first side plate 1112, so that the second housing 112 can be clamped with the first housing 111, and the top plate 1121 can seal the accommodating cavity 110, thereby preventing the inner housing 12 from being separated from the accommodating cavity 110, and limiting a rotation angle of the inner housing 12 in the accommodating cavity 110.

The cross-sectional shape of the first side plate 1112 parallel to the bottom plate 1111 is similar to the shape of the bottom plate 1111, and the cross-sectional area of the first side plate 1112 parallel to the bottom plate 1111 is slightly smaller than the area of the bottom plate 1111. The cross-sectional shape of the second side plate 1122 parallel to the top plate 1121 is the same as the shape of the top plate 1121, i.e., the cross-sectional area of the second side plate 1122 parallel to the top plate 1121 is equal to the area of the top plate 1121. The shape and area of the top plate 1121 are the same as those of the bottom plate 1111, and the cross-sectional area of the second side plate 1122 is slightly larger than that of the first side plate 1112, so that the second side plate 1122 can wrap the first side plate 1112 and be attached to the outer surface of the first side plate 1112, so as to ensure the reliability of the clamping connection between the second housing 112 and the first housing 111. In the present embodiment, the shape of the base plate 1111 is rectangular, and it is understood that the shape of the base plate 1111 may be circular, elliptical, or other shapes, which are not specifically mentioned herein.

One end of the second side plate 1122 away from the top plate 1121 abuts against the bottom plate 1111 to form a first side plate 1112, and the outer surface of the second side plate 1122 is flush with the edge of the bottom plate 1111, so that the second housing 112 and the first housing 111 are covered with good uniformity of appearance.

The bottom plate 1111 is provided with a first mounting hole 11111, the second top plate 1121 is provided with a second mounting hole 11211 corresponding to the first mounting hole 11111, one end of the lens group 20 may be disposed in the first mounting hole 11111, and the other end may be disposed in the second mounting hole 11211.

Alternatively, the inner surface of the first side plate 1112 (i.e., the surface of the first side plate 1112 facing the inner housing 12) may be recessed to form the rolling groove 101 (specifically, the first rolling groove 1011), as shown in fig. 7. The housing assembly 10 may further include a ball 13, where the ball 13 may be partially received in the first rolling groove 1011, so that the inner housing 12 is in point-to-surface contact or point-to-point contact with the ball 13, so that on one hand, the contact area between the inner housing 12 and the outer housing 11 is reduced, and on the other hand, a certain avoiding space may be provided, so that the inner housing 12 can rotate relative to the outer housing 11. In the present embodiment, the first rolling grooves 1011 have a substantially elongated shape, and each first rolling groove 1011 can accommodate at least one ball 13 at the same time and enable the ball 13 to roll in any direction in the first rolling groove 1011. In other embodiments, the balls 13 may be fixed in the first rolling groove 1011, in other words, the balls 13 are part of the outer case 11 so that the outer case 11 is in point-to-point or point-to-point contact with the inner case 12.

The above-mentioned "rolling groove", "first rolling groove" and the below-mentioned "second rolling groove" may be replaced with each other, that is, the "rolling groove" may be replaced with the "first rolling groove" or the "second rolling groove", and the "first rolling groove" may be replaced with the "rolling groove" or the "second rolling groove", which are not listed herein.

Referring to fig. 8, fig. 8 is a schematic cross-sectional view illustrating the cooperation of the outer housing and the inner housing in the camera mechanism shown in fig. 4. In yet another embodiment, the inner surface of the first side plate 1112 may be protruded to form an arc-shaped mounting surface 102 (specifically, the first mounting surface 1021), such as a spherical surface, and the first mounting surface 1021 makes the outer casing 11 and the inner casing 12 point-to-point or point-to-point contact, so that on one hand, the contact area between the inner casing 12 and the outer casing 11 is reduced, and on the other hand, a certain avoiding space may be provided to facilitate the rotation of the inner casing 12 relative to the outer casing 11.

With continued reference to fig. 6, in this embodiment, the mounting groove 103 is disposed on the outer surface of the first side plate 1112 (i.e., the surface where the first side plate 1112 and the second side plate 1122 are attached). The camera mechanism 100 may include a circuit board 50 (e.g., a flexible circuit board), and the circuit board 50 may be mounted in the mounting slot 103. By such design, the space occupied by the circuit board 50 in the accommodating cavity 110 can be reduced, and the space utilization rate of the accommodating cavity 110 can be improved.

Further, the first side plate 1112 may be provided with a receiving hole 104 communicating with the mounting groove 103. The accommodating hole 104 includes a first accommodating hole 1041 along a first direction and a second accommodating hole 1042 along a second direction, and the anti-shake coil 31 of one anti-shake assembly 30 can be accommodated in the first accommodating hole 1041 and electrically connected with the circuit board 50; the anti-shake coil 31 of the further anti-shake assembly 30 can be accommodated in the second accommodating hole 1042 and electrically connected to the circuit board 50. The circuit board 50 can control the current direction and the current magnitude of the anti-shake coil 31, and further control the magnetic field direction and the magnetic field intensity of the anti-shake coil 31.

The receiving hole 104 may further include a third receiving hole 1043, where the third receiving hole 1043 may be disposed along the first direction, may be disposed along the second direction, and may be disposed along other directions, and is not limited herein. The focusing coil 41 can be accommodated in the third accommodating hole 1043 and electrically connected to the circuit board 50. The circuit board 50 can control the current direction and the current magnitude of the focusing coil 41, and further control the magnetic field direction and the magnetic field strength of the focusing coil 41.

As can be appreciated, the anti-shake coil 31 and the focusing coil 41 are accommodated in the corresponding accommodating holes 104, so that the space occupied by the anti-shake coil 31 and the focusing coil 41 in the accommodating cavity 110 can be reduced, and the anti-shake coil 31 and the corresponding anti-shake magnet 32 can be arranged in a clearance manner, and the focusing coil 41 and the corresponding focusing magnet 42 can be arranged in a clearance manner, so that direct absorption of the coils and the magnets can be avoided.

In other embodiments, the circuit board 50 may be directly secured to the inner surface of the first side plate 1112. The anti-shake coil 31 and the focusing coil 41 may be fixed to a surface of the circuit board 50 facing away from the first side plate 1112.

Referring to fig. 9 to 11, fig. 9 is a perspective view of an inner housing in the camera mechanism shown in fig. 4, fig. 10 is a perspective view of a base in the inner housing shown in fig. 9, and fig. 11 is a partially enlarged view of a region B shown in fig. 10. The inner housing 12 may include a base 121, a cover 122 and an elastic member 123, the base 121 having a sliding cavity 120, the cover 122 being used for covering the sliding cavity 120 to restrict a movement range of the lens assembly 20, preventing the lens assembly 20 from being separated from the sliding cavity 120. The elastic member 123 is fixed on the cover 122 and can elastically contact the top plate 1121, the lens assembly 20, and the first side plate 1112, so that on one hand, the collision between the inner housing 12 and the outer housing 11 and the collision between the inner housing 12 and the lens assembly 20 can be reduced, and the abnormal sound of the camera mechanism 100 is prevented, and on the other hand, the foreign matter can be prevented from entering the sliding cavity 120, and the sliding effect of the lens assembly 20 in the sliding cavity 120 is affected.

Specifically, the base 121 may include a substrate 1211 and a baffle 1212 extending from an edge of the substrate 1211, and the sliding cavity 120 is defined by the substrate 1211 and the baffle 1212. The lens group 20 is accommodated in the slide chamber 120 and is capable of sliding on the substrate 1211. The cover 122 includes a cover 1221 and a first fastening structure 105a connected to the cover 1221, and the baffle 1212 is provided with a second fastening structure 105b corresponding to the first fastening structure 105a, where the second fastening structure 105b is fastened to the first fastening structure 105a, so that the cover 122 is connected to the base 121.

Optionally, the housing assembly 10 may further include a rolling member 14, where the rolling member 14 is located between the base plate 1211 and the lens group 20, for reducing friction between the base plate 1211 and the lens group 20, and improving flexibility of movement of the lens group 20 in the sliding cavity 120. Specifically, the rolling members 14 may be balls 13 made of ceramic, plastic, or the like.

Further, the substrate 1211 may be recessed toward one side surface of the lens group 20 to form a sliding groove 106 (specifically, a first sliding groove 1061), and the rolling member 14 is accommodated in the first sliding groove 1061, so that the rolling member 14 can roll in all directions in the first sliding groove 1061, and further the lens group 20 moves in all directions relative to the substrate 1211. It can be appreciated that the first sliding groove 1061 may accommodate the rolling element 14, on one hand, the rolling element 14, to avoid the rolling element 14 from being separated from the lens group 20 and the base 1211, and on the other hand, to limit the moving distance of the lens group 20 in the sliding cavity 120. The sliding groove 106 may have a substantially U-shape or V-shape in cross section to limit the rolling direction of the balls 13.

The above-mentioned "sliding groove", "first sliding groove" and the below-mentioned "second sliding groove" may be replaced with each other, that is, the "sliding groove" may be replaced with the "first sliding groove" or the "second sliding groove", and the "first sliding groove" may be replaced with the "sliding groove" or the "second sliding groove", which are not listed herein.

Specifically, the baffle 1212 may have a first notch 12121 along a first direction and a second notch 12122 along a second direction.
