The inventor finds that the above problem can be improved by providing a reasonable sealing structure, and therefore proposes each camera module and the electronic device in the embodiment of the present application.

The camera module and the electronic device provided by the present application are described below with reference to specific embodiments.

First embodiment

Referring to fig. 1 and fig. 2, the present embodiment provides a camera module 100a, where the camera module 100a may be applied to a terminal device such as an electronic device 10 shown in fig. 10, where the camera module 100a includes a base 110, a mounting member 130, a lens barrel 150, a driving device (not shown), and a sealing ring 120, the mounting member 130 is mounted on the base 110 and forms a receiving cavity 101, the lens barrel 150 is movably disposed in the receiving cavity 101, and the sealing ring 120 is used to seal a gap between the lens barrel 150 and the mounting member 130.

Specifically, the base 110 has a mounting surface 113, and the mounting surface 113 is used for mounting the mounting member 130, wherein the mounting surface 113 may be a plane or other surface. As an example, the substrate 110 may include an image sensor for converting the optical image captured by the lens barrel 150 into an electrical signal in a proportional relationship with the optical image. In another embodiment, the substrate 110 may further include one or more infrared filters, and the infrared filters may be disposed on the surface of the image sensor to filter infrared light. In another embodiment, the substrate 110 may further include a Flexible Printed Circuit (PCB) on which the image sensor is disposed and electrically connected to a Circuit on the PCB.

With continued reference to fig. 2, the mounting member 130 includes a side mounting member 131 and a top mounting member 133, the side mounting member 131 is a substantially annular structure, the side mounting member 131 is mounted on the mounting surface 113 and extends toward one side of the mounting surface 113, the top mounting member 133 is connected to an end of the side mounting member 131 away from the mounting surface 113 and is bent relative to the side mounting member 131, the top mounting member 133 is disposed substantially opposite to the mounting surface 113, the top mounting member 133, the side mounting member 131 and the base 110 enclose a receiving cavity 101, the receiving cavity 101 is used for receiving the lens barrel 150, and the structure of the receiving cavity 101 is not limited herein. It is understood that the side mounting members 131 may be coupled to the base 110 by screws, glue, etc., and the side mounting members 131 and the top mounting member 133 may be integrally formed.

The camera module 100a may further include one or more sealing rubber rings 190, the mounting surface 113 is provided with a sealing groove 111 matched with the sealing rubber ring 190, the sealing groove 111 is located in a contact region between the mounting element 130 and the mounting surface 113, that is, the sealing groove 111 is located in a contact region between the side mounting element 131 and the mounting surface 113, and the sealing rubber ring 190 is embedded in the sealing groove 111 to improve the sealing property of the connection between the side mounting element 131 and the substrate 110. The sealing rubber 190 forms a sealing structure against the side mounting member 131 to prevent impurities such as water, dust, etc. in the air outside the mounting member 130 from entering into the receiving chamber 101.

Referring to fig. 2 again, the top mounting member 133 is provided with a through hole 1331, the through hole 1331 penetrates through the top mounting member 133 and is communicated with the receiving cavity 101, and the through hole 1331 allows the lens barrel 150 to partially extend out of the receiving cavity 101, so the aperture of the through hole 1331, i.e., the inner diameter of the through hole 1331, refers to the diameter of the inscribed circle of the through hole 1331, it should be noted that the through hole 1331 is a circular hole, a rectangular hole, an elliptical hole, a kidney-shaped hole, or any other type of hole, which is not limited herein, and when the through hole 1331 is not a circular hole, the inscribed circle refers to the smallest inscribed circle of the through hole 1331. The inner diameter of the through hole 1331 is adapted to the outer diameter of the lens barrel 150, so that the lens barrel 150 can extend out through the through hole 1331 on one hand, and the overlarge gap between the lens barrel 150 and the top mounting part 133 in the process of extending the lens barrel 150 out of the through hole 1331 on the other hand is avoided. The through hole 1331 may be opened along a central axis of the top mounting member 133, or may be eccentrically disposed. In this embodiment, the cross section of the through hole 1331 is adapted to the cross section of the lens barrel 150.

Referring to fig. 1, fig. 2 and fig. 3, the lens barrel 150 can selectively move along the optical axis direction, and then be selectively received in the receiving cavity 101 or extend out of the through hole 1331, that is, the lens barrel 150 can move in the receiving cavity 101, for example, move towards the top mounting member 133 side to extend out of the through hole 1331, or move towards the mounting surface 113 side of the base 110 to retract into the receiving cavity 101 from outside of the through hole 1331. The optical axis direction refers to an axial direction of the external light received by the lens barrel 150. It should be noted that the term "extending through hole 1331" refers to the final position where the lens barrel 150 reaches the extending through hole 1331, at this time, at least a part of the lens barrel 150 extends out of the accommodating cavity 101 through the through hole 1331, and of course, the lens barrel 150 may extend out of the through hole 1331 completely (as shown in fig. 1); and the accommodation in the accommodation cavity 101 refers to the lens barrel 150 reaching the position contacting with the substrate 110, and at this time, the lens barrel 150 is completely located in the accommodation cavity 101 or mostly located in the accommodation cavity 101 (as shown in fig. 3). The driving force for the movement of the lens barrel 150 comes from a driving device (not shown in the embodiment) which drives the lens barrel 150 to move along the optical axis direction, and the driving device can be a motor, a micro cylinder, or the like. In this embodiment, the driving device is configured as a linear motor structure, and at this time, a coil and a magnet (not shown in the figure) coupled to each other may be disposed on the side mounting member 131 and the lens barrel 150, and when the coil is energized, the lens barrel 150 and the side mounting member 131 can move relative to each other. The position of the lens barrel 150 can be freely selected by arranging the accommodating cavity 101, when the lens barrel 150 is required to be used, the lens barrel 150 extends out, and when the lens barrel is not required to be used, the lens barrel 150 is retracted into the accommodating cavity 101, so that the space occupied by the lens barrel 150 is saved.

As an example, the lens barrel 150 may be slidably disposed along an axial direction of the through hole 1331 and substantially coaxially disposed with the through hole 1331, so that during the movement of the lens barrel 150, a gap between the lens barrel 150 and the through hole 1331 is uniform in all directions, which is beneficial to controlling the sealing performance.

In this embodiment, referring to fig. 1, the lens barrel 150 includes a barrel 151, a frame 153, and a lens assembly 155, the barrel 151 can be accommodated in the accommodating cavity 101, and the barrel 151 can move relative to the mounting member 130. Specifically, the cylinder 151 may be connected to the driving device 160 such that the cylinder 151 may move relative to the mounting member 130 under the driving of the driving device 160, thereby changing the mounting position of the cylinder 151 in the receiving cavity 101. The cylinder 151 is hollow to form a cavity for accommodating the lens holder 153. The frame 153 can be fixedly mounted in the receiving cavity, and the frame 153 can be provided with a mounting cavity, which can be used to receive the lens group 155. The lens assembly 155 can be fixedly mounted in the mounting cavity of the frame 153, so that the stability of the lens assembly 155 is high and the lens assembly 155 is not easily separated from the frame 153 when the lens barrel 150 is moved. For example, the inner surface of the frame 153 can be formed with a plurality of mounting grooves into which the lens set 155 can be mounted and snapped such that the lens set 155 does not fall off the frame 153. The frame 153 and the lens set 155 can follow the barrel 151 as the barrel 151 moves relative to the mount 130. The number of the lens group 155 may be plural, and the lens group 155 may include a concave lens, a convex lens, a half mirror, and the like, which are not listed here. The lens group 155 is used for transmitting external light and guiding the light to the image sensor. In some embodiments, the lens barrel 150 may further include a glass cover plate, and the glass cover plate may be disposed on the light incident side of the lens group 155 to protect the lens group 155.

Referring to fig. 1 and fig. 2, in the present embodiment, the outer wall of the lens barrel 150 is provided with a fixing groove 152, that is, the outer wall of the barrel 151 is provided with a fixing groove 152, the fixing groove 152 is an annular groove and is disposed around the circumference of the outer wall of the barrel 151, and the fixing groove 152 is used for fixing the sealing ring 120. It should be noted that there may be one fixing groove 152 or more than one fixing groove 152, and when there is more than one fixing groove 152, a plurality of fixing grooves 152 may be provided at intervals. The fixing groove 152 may be provided at an end of the cylinder 151 near the substrate 110 to ensure that the lens barrel 150 has a sufficiently long movable path.

The seal ring 120 is used to seal a gap between the lens barrel 150 and the top mount 133 when the lens barrel 150 is extended out of the housing cavity 101. In this embodiment, the sealing ring 120 is embedded in the fixing groove 152 and fixed with respect to the lens barrel 150, that is, the sealing ring 120 and the lens barrel 150 are relatively stationary, and at least part of the sealing ring 120 protrudes out of the fixing groove 152, the outer diameter of the sealing ring 120 is larger than the inner diameter of the through hole 1331, and the outer diameter of the sealing ring 120 is the diameter of the outer circle of the sealing ring 120, so that when the lens barrel 150 moves, the sealing ring 120 cannot extend into the through hole 1331. When the lens barrel 150 moves to extend out of the through hole 1331, the sealing ring 120 abuts against the top mounting piece 133, and at this time, the sealing ring 120 receives a pressing force from the top mounting piece 133 along the axial direction of the through hole 1331, so that the gap between the top mounting piece 133 and the lens barrel 150 is sealed, and impurities such as water and dust in the outside air are prevented from entering the accommodating cavity 101.

The sealing ring 120 is of an annular structure and can be made of flexible and deformable materials such as silica gel and rubber, so that the sealing ring 120 deforms in the process that the sealing ring 120 is abutted to the top mounting piece 133, and part of the sealing ring 120 can be embedded into the through hole 1331 to form sealing, so that the sealing performance of a gap between the top mounting piece 133 and the lens barrel 150 is better. In order to prevent the seal ring 120 from falling out of the fixing groove 152 by the pressure from the top attachment member 133 during the abutment of the seal ring 120 with the top attachment member 133, the portion of the seal ring 120 fitted into the fixing groove 152 may be greater than or equal to 1/2, which is the volume of the seal ring 120, so that the center of gravity of the seal ring 120 is located in the fixing groove 152 and is not easily removed from the fixing groove 152 when the pressure from the top attachment member 133 is applied. Further, the part of the sealing ring 120 embedded in the fixing groove 152 can be connected with the lens barrel 150 through glue, so that the connection between the sealing ring 120 and the lens barrel 150 is further enhanced, and the sealing ring is prevented from falling off.

As an alternative embodiment, in this embodiment, referring to fig. 1 and fig. 2 again, the mounting component 130 may further include a mounting portion 170, the mounting portion 170 is mounted on the top mounting component 133 and is located on a side of the top mounting component 133 away from the base 110, and the mounting portion 170 and the top mounting component 133 may be connected by a screw connection, an adhesive connection, a clamping connection, or the like. A mounting cavity 173 is formed between the mounting part 170 and the top mounting part 133, the mounting cavity 173 has an opening facing the axis of the through hole 1331, the mounting cavity 173 is disposed around the axis of the through hole 1331, the mounting part 170 has an avoiding hole 171 coaxial with the through hole 1331, and when the lens barrel 150 extends out of the through hole 1331, the avoiding hole 171 can also extend out. The avoiding hole 171 may have the same inner diameter as the through hole 1331 to prevent the lens barrel 150 from being scratched during the extension process of the lens barrel 150.

The camera module 100a further includes a sealing body 180, the sealing body 180 is disposed in the mounting cavity 173 and protrudes toward the axial direction of the through hole 1331, the sealing body 180 may protrude from the mounting cavity 173 and partially extend into the avoiding hole 171, so that in the sliding process of the lens barrel 150, the sealing body 180 may contact with the outer wall of the lens barrel 150, and in the sliding process of the whole lens barrel 150, the sealing body 180 always contacts with the outer wall of the lens barrel 150 to form a seal. Through the arrangement, the sealing body 180 is always in contact with the lens barrel 150, so that a gap between the lens barrel 150 and the mounting part 170 can be sealed at any time, the probability that impurities such as water and dust in the air enter the receiving cavity 101 is reduced, and the waterproof and dustproof performance of the camera module 100a is further improved.

The sealing body 180 may be fixedly disposed in the mounting cavity by interference, adhesion, or the like, which is not limited herein. As an example, in this embodiment, referring to fig. 4, the sealing body 180 includes a contact portion 181 and a main body portion 182, the main body portion 182 is embedded in the mounting cavity 173, the contact portion 181 is connected with the main body portion 182 and partially extends into the avoiding hole 171 for contacting with the lens barrel 150 to form a seal, wherein the contact portion 181 and the lens barrel 150 may have at least one contact point therebetween, in this embodiment, the main body 182 is provided with a fitting groove 183, the mounting part 170 is provided with a fitting part 172 which is matched with the fitting groove 183, the fitting part 172 extends towards the base 110 to the mounting cavity and is embedded into the fitting groove 183, further, the sealing body 180 is fixed relative to the sealing body 180, and the sealing body 180 cannot be removed from the mounting cavity along the radial direction of the avoiding hole 171 by the fitting part 172, so that during the movement of the lens barrel 150, the frictional force generated between the sealing body 180 pulls the sealing body 180 out of the mounting cavity.

In some embodiments, the contact portion 181 may have more than one contact point with the lens barrel 150, for example, two contact points or three contact points, which may increase the sealing property between the sealing body 180 and the lens barrel 150.

In the camera module 100a provided in this embodiment, when the lens barrel 150 extends out of the through hole 1331, the sealing ring 120 abuts against the top mounting member 133, so as to seal the gap between the top mounting member 133 and the lens barrel 150, thereby preventing impurities such as water and dust in the outside air from entering the accommodating cavity 101.

Second embodiment

Referring to fig. 5 and fig. 6 together, the present embodiment provides a camera module 100b, and the difference between the camera module 100b provided by the present embodiment and the camera module 100a provided by the first embodiment is that the fixing manner of the sealing ring 120 in the present embodiment is different from that in the first embodiment, and the same parts are not described herein again, and the related contents of the first embodiment can be referred to.

Specifically, in this embodiment, referring to fig. 5, the outer wall of the lens barrel 150 is provided with a protrusion 157, the protrusion 157 is located at one end of the lens barrel 150 close to the base 110, and the protrusion 157 is connected to the outer wall of the cylinder 151 of the lens barrel 150 and protrudes toward the side mounting member 131. The protrusion 157 may be disposed around the outer wall of the cylinder 151 to form a ring shape, or may be composed of a plurality of portions spaced apart from each other. The protrusion 157 is larger than the inner diameter of the through hole 1331 in the radial direction of the cylinder 151, so that during the movement of the lens barrel 150, the protrusion 157 can be clamped on the top mounting member 133, and the lens barrel 150 is prevented from completely falling out of the accommodating cavity 101.

The sealing ring 120 is disposed on the outer wall of the lens barrel 150, the sealing ring 120 is located between the protrusion 157 and the top mounting part 170 and contacts with the protrusion 157, when the lens barrel 150 extends out of the mounting part 130, the protrusion 157 presses the sealing ring 120 against the top mounting part 133, at this time, the sealing ring 120 receives a pressing force from the protrusion 157 along the axial direction of the through hole 1331 and toward the top mounting part 133, and receives a pressing force from the top mounting part 133 along the axial direction of the through hole 1331 and toward the protrusion 157, so that the sealing ring 120 is sufficiently deformed and seals the gap between the lens barrel 150 and the top mounting part 133, thereby achieving a better sealing effect.

To further improve the sealing effect, in some embodiments, referring to fig. 5 and fig. 7, top mounting element 133 is provided with a protruding portion 1332 engaged with sealing ring 120, protruding portion 1332 is disposed adjacent to through hole 1331, and the projection of protruding portion 1332 on base 110 falls within the projection range of sealing ring 120 on base 110, protruding portion 1332 has at least one contact point with sealing ring 120, that is, when protruding portion 1332 approaches sealing ring 120, the contact point on protruding portion 1332 can contact sealing ring 120. The contact point may be a point, a line, or a plane, which is not limited herein.

This embodiment, in which the seal ring 120 is pressed against the top mounting member 133 and the projection 1332 is at least partially embedded in the seal ring 120 when the barrel 150 is extended out of the mounting member 130, has the following advantages: when the protruding portion 1332 is inserted into the sealing ring 120, as shown in fig. 7, the sealing ring 120 is divided into at least two parts, and the sealing ring 120 is pressed by the protruding portion 157 and the top mounting member 133, so that the protruding portion 1332 is deformed and wraps the protruding portion 1332, and thus the surface of the sealing ring 120 presents an irregular interface, and impurities such as water and dust in the air are difficult to enter, thereby further improving the sealing effect. In some embodiments, the protrusion 1332 may have at least two contact points with the sealing ring 120, and the at least two contact points with the sealing ring 120 may be spaced apart from each other, which may further improve the sealing effect.

When the lens barrel 150 is accommodated in the accommodating cavity 101, the sealing ring 120 retracts into the accommodating cavity 101 along with the lens barrel 150, a certain gap exists between the lens barrel 150 and the top mounting member 133, and water, dust and the like in the air may affect sensitive elements of the substrate 110 and elements in the lens barrel 150 after entering the accommodating cavity 101, so as to avoid such a situation. In this embodiment, referring to fig. 5 again, the camera module 100b further includes a gasket 140, the gasket 140 is disposed on the mounting surface 113, as shown in fig. 6, when the lens barrel 150 is accommodated in the accommodating cavity 101, the gasket 140 abuts against the lens barrel 150, so that the lens group 155 in the lens barrel 150 can be isolated from the air in the accommodating cavity 101, and thus the impurities can be prevented from entering the barrel 151 to adversely affect the lens group 155.

The sealing pad 140 may also be disposed in a manner of surrounding a sensitive element on the substrate 110, and when the lens barrel 150 is accommodated in the accommodating cavity 101, the sealing pad 140 abuts against the lens barrel 150, so that the sealing pad 140 does not affect the image sensor to obtain the external light guided by the lens group 155, and isolates the image sensor together with the lens barrel 150, thereby providing better waterproof and dustproof effects for components such as the image sensor on the substrate 110. In this case, the gasket 140 may be disposed in a projection range of the protrusion 157 on the substrate 110, so that when the lens barrel 150 is accommodated in the accommodating cavity 101, the gasket 140 abuts against the protrusion 157, and the gasket 140 seals a gap between the lens barrel 150 and the substrate 110.

When the gasket 140 is disposed, the gasket 140 may be directly adhered to the substrate 110, and at this time, the protrusion 157 may form a mounting groove on a surface facing the substrate 110, and the mounting groove may be fitted with the gasket 140 so that the gasket 140 may be inserted into the mounting groove. In this embodiment, as shown in fig. 5, the mounting surface 113 is provided with a slot 112, and the sealing pad 140 is embedded in the slot 112 and at least partially protrudes from the mounting surface 113. The portion of the gasket 140 protruding from the mounting surface 113 is configured to abut against the protrusion 157 to form a seal, which may facilitate securing the gasket 140.
