The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.

Referring to fig. 1 to 3 together, fig. 1 is a schematic structural diagram of a camera module according to a first aspect of the present invention, fig. 2 is an exploded schematic structural diagram of a camera module according to a first aspect of the present invention, and fig. 3 is a sectional view taken along a direction a-a in fig. 1. The embodiment of the utility model discloses a first aspect discloses a camera module 1, turn to component 5 including module casing 3, optical lens 31, chip subassembly 4 and light. The module housing 3 includes a housing portion 2 and a lens barrel portion 30, the housing portion 2 has a first side 20 and a second side 21, the housing portion 2 further has an accommodating space 22, the lens barrel portion 30 is located on the first side 20, the optical lens 31 is disposed in the lens barrel portion 30, an image side of the optical lens 31 faces the accommodating space 22, the chip assembly 4 is disposed on the second side 21 of the housing portion 2, the light redirecting element 5 is disposed in the accommodating space 22, and the light redirecting element 5 is configured to reflect light emitted from the optical lens 31 to a light-sensing surface 40 of the chip assembly 4.

The utility model discloses a camera module 1 disclosed in the first aspect has eliminated the assembly tolerance of lens barrel portion 30 when installing in casing portion 2 through making lens barrel portion 30 and casing portion 2 integrated into one piece to reduce the accumulative assembly tolerance between optical lens 31 and the light steering element 5, be favorable to promoting camera module 1's imaging quality.

Alternatively, the first side 20 and the second side 21 may be adjacent two sides of the housing portion 2, or may be opposite two sides of the housing portion 2. The first side 20 and the second side 21 refer to the two side orientations of the housing 2 and the portions of the housing 2 located on the two sides, respectively, that is, the first side 20 and the second side 21 include both the virtual orientations and the partial physical structures of the housing 2.

It can be understood that, since the chip component 4 is substantially formed into a sheet shape with a thickness dimension much smaller than the length and width dimensions of one side of the light sensing surface 40, when the first side 20 and the second side 21 are adjacent two sides of the housing 2, the light sensing surface 40 of the chip component 4 can be substantially parallel to the optical axis O of the optical lens 31, so that one side of the chip component 4 with a larger dimension is substantially parallel to the optical axis O of the optical lens 31, thereby making the projection area of the chip component 4 on a plane perpendicular to the optical axis O smaller, so that the size of the camera module 1 as a whole in a direction perpendicular to the optical axis O is smaller, and further, while ensuring the imaging quality, the miniaturized design of the camera module 1 can be realized.

In some embodiments, the lens barrel portion 30 may further include a lens limiting portion 23, and the lens limiting portion 23 abuts against one side of the optical lens 31 in the direction of the optical axis O to limit the position of the optical lens 31 in the lens barrel portion 30, so as to improve the mounting position accuracy of the optical lens 31 in the lens barrel portion 30, and further improve the relative position accuracy between the optical lens 31 and the light turning element 5 and the chip assembly 4, so as to further improve the shooting quality of the camera module 1.

Alternatively, the lens stopper portion 23 may abut against a side of the optical lens 31 facing the first side 20 to enable the optical lens 31 to be mounted into the lens barrel portion 30 from a side of the lens barrel portion 30 opposite to the housing portion 2 while enabling the position of the optical lens 31 in the lens barrel portion 30 to be limited, so that the mounting operation space of the optical lens 31 is large and the mounting difficulty is small. It is understood that, in other embodiments, the lens limiting portion 23 may also abut against the surface of the optical lens 31 facing away from the first side 20.

Further, the lens limiting portion 23 can abut against the edge portion of the optical lens 31 to prevent the lens limiting portion 23 from blocking light rays passing through the middle portion of the optical lens 31, so that imaging defects are caused, and the shooting quality of the camera module 1 is improved.

It is understood that the specific structure of the lens position limiting portion 23 can be selected according to the actual use and design requirements.

In an alternative embodiment, the lens position limiting portion 23 may be formed to protrude from the inner surface of the lens barrel portion 30 around the optical axis O to be a convex ring, or to be a plurality of protruding blocks or protruding strips arranged in a spaced ring, so that the lens position limiting portion 23 can avoid the middle portion of the optical lens 31 in the optical axis O direction, and the surface of the lens position limiting portion 23 facing the optical lens 31 abuts against the edge portion of the optical lens 31.

In another alternative embodiment, the surface of the first side 20 may be formed as the lens position limiting portion 23, so that the lens position limiting portion 23 can abut against the side of the optical lens 31 facing the first side 20, and the surface of the first side 20 of the housing portion 2 also has the function of the lens position limiting portion 23, thereby making the structure of the image pickup module 1 simpler and more compact.

It can be seen that, whatever the specific structure of the lens limiting portion 23 is, the function of limiting the position of the optical lens 31 in the lens barrel portion 30 by the lens limiting portion 23 is essentially realized by the one side surface of the lens limiting portion 23 facing the optical lens 31 abutting against the optical lens 31 in the direction of the optical axis O. Therefore, in order to achieve more accurate position limitation of the optical lens 31, the requirements for the dimensional accuracy, the positional accuracy, and the surface roughness of the one side surface of the lens position limiting portion 23 are high, so that the one side surface of the lens position limiting portion 23 needs to be finished in the manufacturing process.

In an alternative embodiment, the surface of the lens holder 23 on the one side abuts against the surface of the optical lens 31 facing the first side 20, in other words, the surface of the lens holder 23 on the one side faces the side of the lens barrel 30 facing away from the housing part 2, and at this time, a finishing tool can be inserted into the lens barrel 30 through the side of the lens barrel 30 facing away from the housing part 2 to finish the surface of the lens holder 23 on the one side.

In another alternative embodiment, the barrel portion 30 may be provided with a clearance groove 24, the clearance groove 24 is communicated with the accommodating space 22 and is located on a side of the lens limiting portion 23 facing the optical lens 31, and the clearance groove 24 is used for allowing a tool to pass through so as to clearance the tool when the tool enters the interior of the barrel portion 30 to process the lens limiting portion 23.

In order to avoid that impurities such as water and dust and stray light enter the lens barrel portion 30 through the clearance groove 24 and affect the shooting quality of the camera module 1, further, after finishing the finish machining of the surface of the lens limiting portion 23, a shading material, such as shading UV glue (photosensitive glue), hot melt glue, sealant and the like, may be filled in the clearance groove 24.

As shown in fig. 3, in order to enable light to enter the accommodating space 22 from the optical lens 31 through the first side 20 of the housing portion 2, in an alternative embodiment, the first side 20 of the housing portion 2 is provided with a first opening 200, and the first opening 200 is communicated with the inside of the lens barrel portion 30 and communicated with the accommodating space 22, that is, the light can pass through the first side 20 by way of the opening. In another alternative embodiment, the first side 20 may be at least partially formed of a transparent material (e.g., transparent glass, plastic, etc.) so as to be at least partially transparent, the lens barrel portion 30 is connected to the first side 20, and the optical lens 31 corresponds to the transparent portion, so that light can pass through the first side 20.

In some embodiments, the light diverting element 5 may be a prism, a pentaprism, a mirror or other optical element that may have a reflective surface 51 to redirect light rays through the reflective surface 51 to receive light rays emitted from the optical lens 31 and reflect the light rays to the light sensing surface 40 of the chip assembly 4.

Referring to fig. 3 to 5, taking the light turning element 5 as a prism as an example, the light turning element 5 may further include a light incident surface 52, a light emitting surface 53, a first side surface 54 and a second side surface 55, the light incident surface 52 faces the optical lens 31, the light emitting surface 53 faces the chip module 4, the light emitting surface 53 is perpendicular to the light incident surface 52, the first side surface 54 and the second side surface 55 are disposed opposite to each other, the first side surface 54 is connected to the light incident surface 52, the light emitting surface 53 and the reflection surface 51, and the second side surface 55 is connected to the light incident surface 52, the light emitting surface 53 and the reflection surface 51. By orienting the light incident surface 52 to the optical lens 31, the light rays can be refracted at the light incident surface 52 at the same time when being emitted from the optical lens 31 to the light turning element 5, and by orienting the light emitting surface 53 to the chip module 4, the light rays can be refracted at the light emitting surface 53 at the same time when being emitted from the light turning element 5 to the chip module 4, so that the phenomena of distortion and deformation of the image detected by the chip module 4 can be alleviated, and the shooting quality of the camera module 1 can be improved, wherein the reflecting surface 51 and the second side surface 55 in fig. 4 are shielded by the light incident surface 52, the light emitting surface 53 and the first side surface 54, and therefore the edge where the reflecting surface 51 and the second side surface 55 intersect is shown by a dotted line.

In order to make the image of the light on the light-sensing surface 40 of the chip component 4 clear, the distance from the light to the reflecting surface 51 and then to the light-sensing surface 40 of the chip component 4 through the optical lens 31 may be approximately equal to the focal length of the lens, in other words, the light needs to have a sufficiently long propagation distance. Accordingly, the light incident surface 52 and the optical lens 31 can be spaced apart from each other, so that the distance between the light incident surface 52 and the optical lens 31 can be increased or decreased to increase or decrease the propagation distance of the light, so that the propagation distance between the optical lens 31 and the chip assembly 4 is substantially equal to the focal length of the optical lens 31.

In some embodiments, the accommodating space 22 may further include a component limiting portion 25, the component limiting portion 25 is located on at least one side of the light turning component 5, for example, when the light turning component 5 is a prism, the component limiting portion 25 may be located on one side of at least one of the reflection surface 51, the light incident surface 52, the light emitting surface 53, the first side surface 54 and the second side surface 55 of the light turning component 5, so as to limit the position of the light turning component 5 in the accommodating space 22, thereby improving the position accuracy of the light turning component 5 when being mounted on the housing portion 2, further improving the relative position accuracy of the reflection surface 51 and the optical lens 31, and the reflection surface 51 and the chip assembly 4, and further improving the imaging quality of the camera module 1.

It should be noted that the "element limiting portion 25 is located at one side of the light turning element 5" in the foregoing description means that the element limiting portion 25 abuts against the surface of the one side of the light turning element 5 to accurately limit the light turning element 5, or the element limiting portion 25 is adjacent to the surface of the one side of the light turning element 5, and the surface of the element limiting portion 25 facing the light turning element 5 is substantially parallel to the surface of the one side of the light turning element 5 to substantially limit the light turning element 5.

Further, a side of the element limiting portion 25 facing the light redirecting element 5 forms an element disposing space 220, or the element limiting portion 25 may be plural, the element disposing space 220 is formed between the plural element limiting portions 25, the element limiting portion 25 may be located in the element disposing space 220, and the element disposing space 220 is used for indicating a general mounting position of the light redirecting element 5 when the light redirecting element 5 is mounted on the housing portion 2, and is used for accommodating at least a part of the light redirecting element 5.

It will be appreciated that when the element-defining part 25 is located on different sides of the light redirecting element 5, the light redirecting element 5 can be defined from different sides, thereby achieving different definition requirements.

Referring to fig. 4 to fig. 6, in an alternative embodiment, the element limiting portion 25 abuts on at least one side of the light turning element 5 along the optical axis O direction of the optical lens 31, so as to precisely limit the relative position of the light turning element 5 and the optical lens 31 along the optical axis O direction, thereby improving the imaging quality of the camera module 1.

Alternatively, the element limiting portion 25 may abut against a side surface of the light turning element 5 (i.e., the reflection surface 51) away from the optical lens 31 along the optical axis O direction, so as to improve the relative position accuracy between the reflection surface 51 and the optical lens 31 along the optical axis O direction, or the element limiting portion 25 may abut against a side surface of the light turning element 5 facing the optical lens 31 (e.g., the light incident surface 52 of the light turning element 5 when the light turning element 5 is a prism), so as to improve the relative position accuracy between the light turning element 5 and the optical lens 31 along the optical axis O direction, or the element limiting portion 25 may abut against two opposite surfaces of the light turning element 5 along the optical axis O direction (e.g., the reflection surface 51 and the light incident surface 52 of the light turning element 5 when the light turning element 5 is a prism), so as to achieve a more comprehensive limiting effect on the light turning element 5 and the reflection surface 51, the relative positional accuracy of the light redirecting element 5, the reflecting surface 51, and the optical lens 31 in the direction of the optical axis O is higher.

Next, the specific structure of the element stopper 25 when the light turning element 5 is a prism and the element stopper 25 abuts against the reflection surface 51 and the light incident surface 52 will be described with reference to the drawings.

When the element-limiting portion 25 abuts against the reflective surface 51, in an alternative example, the accommodating space 22 may include an inner wall surface 510 matched with the reflective surface 51, and the inner wall surface 510 may be formed as the element-limiting portion 25, in other words, the element-limiting portion 25 may be a part of the inner wall surface 510 of the housing portion 2, in this embodiment, a projection of the element-limiting portion 25 on the reflective surface 51 generally covers the reflective surface 51, so that the effective reflective surfaces 51 of the element-limiting portion 25 and the reflective surface 51 have a large volume and a stable limiting effect. In addition, since the element limiting portion 25 can completely cover the reflection surface 51, the element limiting portion 25 can also achieve the effect of preventing stray light from entering the reflection surface 51, and the imaging quality of the camera module 1 is improved, wherein the element limiting portion 25 is shielded by the light turning element 5 in fig. 6, and therefore the structural outline shape of the element limiting portion 25 is shown by a dotted line.

In another alternative example, the element-limiting portion 25 may be a protrusion, such as a bump or a convex strip, disposed in the accommodating space 22, in this embodiment, the surface area of the element-limiting portion 25 abutting against the reflection surface 51 is generally smaller, so that the surface is easier to manufacture with high precision compared to a surface with a larger area.

Further, the element limiting portion 25 can abut against the edge area of the reflecting surface 51, so that the limiting effect of the reflecting surface 51 is realized, and meanwhile, the phenomenon that the element limiting portion 25 generates projection in the middle of the reflecting surface 51 to cause generation of black shadow in imaging of the camera module 1 is avoided, and the imaging quality of the camera module 1 is improved.

Optionally, the element limiting portion 25 may at least abut against edge regions of two opposite sides of the reflection surface 51, so as to abut against the two opposite sides of the reflection surface 51, so that the effect of the limiting effect on the reflection surface 51 is more balanced, and the limiting effect of the element limiting portion 25 on the reflection surface 51 is stable.

Specifically, regarding the reflecting surface 51, when the reflecting surface 51 is viewed from the front view of the reflecting surface 51, the reflecting surface 51 generally has four sides of the upper side, the lower side, the left side and the right side, and the element stopper portion 25 may abut against edge regions of two opposite sides of the reflecting surface 51, for example, edge regions located at the upper side and the lower side, or the left side and the right side of the reflecting surface 51, or may abut against three sides of the reflecting surface 51, for example, edge regions located at the upper side, the lower side and the left side, the upper side, the lower side and the right side, the left side, the right side and the upper side, or edge regions located at the left side, the right side and the lower side of the reflecting surface 51, or may abut against edge regions located at four sides of the upper side, the lower side, the left side and the right side of the reflecting surface 51.

As shown in fig. 4 and 6, preferably, there may be two element limiting portions 25, and the two element limiting portions 25 are spaced apart and respectively abut against the edge regions of the two opposite sides of the reflection surface 51, so that the reflection surface 51 can be effectively limited by the element limiting portions 25 with the minimum volume, and the housing portion 2 is simpler and more compact in structure.

Alternatively, the element stopper 25 may have an elongated shape so as to be capable of substantially abutting against an edge region on one side of the reflection surface 51. Further, the end 25a of the element stopper 25 may be bent so that the end 25a extends to correspond to an edge region located on the adjacent side of the one-side reflecting surface 51, thereby increasing an effective stopper contact area between the element stopper 25 and the reflecting surface 51.

Optionally, the accommodating space 22 may further include an inner wall surface 510 matched with the reflecting surface 51, and the element limiting portion 25 is disposed on the inner wall surface 510, so that, on one hand, stray light can be blocked by the inner wall surface 510, and stray light can be prevented from being emitted to the reflecting surface 51 from one side of the reflecting surface 51, on the other hand, because the element limiting portion 25 is convexly disposed on the inner wall surface 510, and the reflecting surface 51 abuts against the element limiting portion 25, there is a gap between the inner wall surface 510 and the reflecting surface 51, so as to prevent a shadow from being formed in the middle of the reflecting surface 51 due to the fact that the inner wall surface 510 is attached to the reflecting surface 51, thereby preventing a shadow from being generated in an image shot by the camera module 1, and further improving the shooting quality of the camera module 1.

In the above description, "inner wall surface 510 matching reflection surface 51" means that the shape of inner wall surface 510 is substantially equal to the shape of reflection surface 51, and inner wall surface 510 is substantially parallel to reflection surface 51.

As shown in fig. 5, it is understood that the distance between inner wall surface 510 and reflection surface 51 is substantially equal to height h of element stopper 25 in the direction perpendicular to inner wall surface 510, and the distance between inner wall surface 510 and reflection surface 51 cannot be excessively large in order to improve the light shielding effect of inner wall surface 510. Based on this, the height h of the element stopper portion 25 in the direction perpendicular to the inner wall surface 510 may satisfy the following relation: h is less than or equal to 0.1mm, for example, the height h can be 0.1mm, 0.09mm, 0.08mm, 0.07mm, 0.06mm, 0.05mm, 0.04mm, 0.03mm, 0.02mm, 0.01mm, or the like.

When the element-limiting portion 25 abuts against the light incident surface 52 of the light turning element 5, optionally, the element-limiting portion 25 may be in the shape of a bump or a protrusion protruding from the accommodating space 22, so that the element-limiting portion 25 has a surface protruding from the inner surface of the accommodating space 22, and can abut against the side of the light turning element 5 facing the first side 20 through the surface protruding from the housing portion 2.

Optionally, the element limiting portion 25 may abut against an edge region of the light incident surface 52, so as to avoid the element limiting portion 25 from blocking the light emitted from the optical lens 31 while achieving the limiting effect on the light incident surface 52, thereby avoiding the element limiting portion 25 from affecting the imaging quality of the camera module 1.

Further, the element limiting portions 25 may abut against the edge regions on the two opposite sides of the light incident surface 52, so that the limiting effect of the element limiting portions 25 on the light turning element 5 is more balanced and stable, as shown in fig. 4 and 6, fig. 4 and 6 show two element limiting portions 25, and the two element limiting portions 25 are respectively disposed corresponding to the edge regions on the two opposite sides of the light incident surface 52.

Referring to fig. 4, 6 and 7, in another alternative embodiment, the device position-limiting portion 25 may be located on at least one side of the light turning device 5 along a direction perpendicular to the optical axis O to substantially indicate and limit the installation position of the light turning device 5.

It is understood that the element limiting portions 25 may be located on any side of the light turning element 5 in the direction perpendicular to the optical axis O, so that the structure of the housing portion 2 is simple, or there may be two element limiting portions 25, and the two element limiting portions 25 may be located on two opposite sides of the light turning element 5 in the direction perpendicular to the optical axis O, respectively, so as to achieve a more comprehensive limiting effect.

As shown in fig. 7, alternatively, a recess 250 may be formed on the outer surface of the housing 2 corresponding to the component stopper 25, so that the overall size of the camera module 1 is reduced and a more compact design can be achieved.

When the light redirecting element 5 is a triangular prism, in particular, the element limiting section 25 may be provided to protrude toward the first side surface 54 so as to limit the limit position of the light redirecting element 5 from the side of the first side surface 54 of the light redirecting element 5 by the element limiting section 25, or the element limiting section 25 may be provided to protrude toward the second side surface 55 so as to limit the limit position of the light redirecting element 5 from the side of the second side surface 55 of the light redirecting element 5 by the element limiting section 25, or the element limiting sections 25 may be two, and two element limiting sections 25 may be provided to protrude toward the first side surface 54 and the second side surface 55, respectively, with an element setting space 220 formed between the two element limiting sections 25, and the element limiting section 25 may be located in the element setting space 220 so as to accommodate at least part of the light redirecting element 5 through the element setting space 220.

In yet another optional embodiment, the element-limiting portion 25 may include a first limiting portion 251 and a second limiting portion 252, the first limiting portion 251 abuts against at least one side of the light turning element 5 along the optical axis O direction of the optical lens 31, and the second limiting portion 252 is located at least one side of the light turning element 5 along the direction perpendicular to the optical axis O, so that the position of the light turning element 5 can be limited from more directions, and a more comprehensive limiting effect on the light turning element 5 can be achieved. It can be understood that, the specific structure of the first position-limiting portion 251 is described in the foregoing, when the element-limiting portion 25 abuts on at least one side of the light-turning element 5 along the direction of the optical axis O of the optical lens 31, the specific structure of the element-limiting portion 25 is described, and the specific structure of the second position-limiting portion 252 is described in the foregoing, when the element-limiting portion 25 is located on at least one side of the light-turning element 5 along the direction perpendicular to the optical axis O, the specific structure of the element-limiting portion 25 is described, and will not be described again here.

As mentioned above, the accommodating space 22 may have an inner wall surface 510 matching the reflective surface 51, and at this time, the second limiting portions 252 may be connected to one side of the inner wall surface 510, or two second limiting portions 252 may be provided, and the two second limiting portions 252 are respectively located at two opposite sides of the light turning element 5 and respectively connected to two opposite sides of the inner wall surface 510, so that the inner surface of the housing portion 2 facing the accommodating space 22 is continuous and reasonable.

When the first position-limiting portion 251 is protruded on the inner wall surface 510, optionally, the first position-limiting portion 251 and the second position-limiting portion 252 may be disposed at an interval, so as to avoid mutual influence of the structures of the first position-limiting portion 251 and the second position-limiting portion 252 during the manufacturing process, which may result in difficulty in meeting the design requirement of the structural accuracy of the first position-limiting portion 251. Alternatively, the first position-limiting portion 251 and the second position-limiting portion 252 may be connected to make the inner surface of the housing portion 2 facing the accommodating space 22 continuous.

Referring again to fig. 5, it can be appreciated that the edge portion of the light diverting element 5, particularly when the light diverting element 5 is a triangular prism, is structurally fragile and is susceptible to breakage upon impact. Based on this, in some embodiments, a groove 26 may be further disposed in the accommodating space 22, the groove 26 is located at an end of the light turning element 5 away from the chip assembly 4, and a partial groove wall of the groove 26 abuts against a side of the light turning element 5 facing the lens barrel portion 30, so that when the light turning element 5 is disposed in the accommodating space 22, a gap is formed between a groove bottom surface of the groove 26 and an edge portion of the side of the light turning element 5 away from the chip assembly 4 (i.e., when the light turning element 5 is a triangular prism, an edge portion where the incident surface 52 and the reflecting surface 51 intersect), in other words, the edge portion of the light turning element 5 is not easily collided with the housing portion 2, so as to avoid the light turning element 5 from being damaged.

Further, a side edge portion of the light turning element 5 facing away from the chip assembly 4 may be located in the groove 26, and a side surface of the light turning element 5 facing the lens barrel portion 30 (i.e., when the light turning element 5 is a prism, the light incident surface 52 of the light turning element 5) may abut against a part of a groove wall of the groove 26, that is, a part of a groove wall of the groove 26 facing away from the lens barrel portion 30 may be formed as the element stopper portion 25, so that the groove 26 can be partially formed as the element stopper portion 25 while achieving a function of avoiding the side edge portion of the light turning element 5, so as to achieve a function of stopping the side surface of the light turning element 5 facing the first side 20, and the function of the groove 26 is more various.

Referring to fig. 4, fig. 6 and fig. 8, in some embodiments, in order to relatively fix the position of the light redirecting element 5 in the accommodating space 22, the light redirecting element 5 may be fixedly connected to the housing portion 2, or the light redirecting element 5 may be fixedly connected to the chip assembly 4.

Preferably, the light redirecting element 5 is fixedly connected to the housing 2 so as to be able to fix the relative position of the light redirecting element 5 and the housing 2 while the light redirecting element 5 is restricted by the element restricting portion 25, so that the light redirecting element 5 is easily maintained at the position defined by the element restricting portion 25 during use of the camera module 1, i.e., the light redirecting element 5 is easily maintained in a state of high optical accuracy.

Specifically, the accommodating space 22 may further include a dispensing slot 27, the light redirecting element 5 is disposed in the element disposing space 220 and forms a dispensing space 221 with the dispensing slot 27, and the dispensing space 221 is used for accommodating an adhesive medium, so that the light redirecting element 5 can be adhesively connected to the housing portion 2 by means of dispensing, so that the light redirecting element 5 is fixed in the accommodating space 22.

In order to increase the connection area of the adhesive medium with the housing portion 2 and the light redirecting element 5, respectively, so as to make the connection between the housing portion 2 and the light redirecting element 5 more stable, in an alternative example, one dispensing slot 27 may be provided, and the dispensing slot 27 may be long, so that the arrangement area of the adhesive medium can be increased, and the connection area of the adhesive medium with the housing portion 2 and the light redirecting element 5, respectively, can be increased.

In another alternative example, the dispensing grooves 27 may be multiple, the dispensing grooves 27 are arranged at intervals, and a dispensing space 221 is formed between each dispensing groove 27 and the light redirecting element 5, so that the number of the dispensing grooves 27 is increased to increase the arrangement area of the adhesive medium, and thus the connection area between the adhesive medium and the housing 2 and the light redirecting element 5 is increased.

In still another alternative example, the dispensing slot 27 may be long, and a plurality of dispensing slots 27 are provided, and the dispensing slots 27 are arranged at intervals, so as to increase the arrangement area of the adhesive medium more, and thus increase the connection area between the adhesive medium and the housing 2 and the light redirecting element 5, respectively.

Further, the dispensing grooves 27 may be spaced apart from each other in a direction perpendicular to the extending direction of the dispensing grooves 27, so that the disposing positions of the dispensing grooves 27 are more compact, the disposing positions of the adhesive medium are more compact, the adhesive strength of the adhesive medium can be more effectively enhanced, and the connection between the housing portion 2 and the light redirecting element 5 is further more stable.

It is understood that the dispensing space 221 has a dispensing opening 270, and the dispensing opening 270 is used for providing an Adhesive medium (e.g., UV glue (photosensitive glue), hot melt glue or OCA glue (Optically Clear Adhesive) to enter the dispensing space 221), and the applicant has found that, due to the small volume of the camera module 1, the size of the dispensing slot 27 provided in the housing portion 2 and the dispensing opening 270 of the dispensing space 221 is also small, so that during the dispensing process, it is difficult for the dispensing head to precisely align the dispensing opening 270 to fill the dispensing slot 27 with the Adhesive medium. Based on this, in some embodiments, a drainage surface 271 may be disposed at a position of the housing portion 2 near the dispensing opening 270, the drainage surface 271 may be formed as an inclined surface or a curved surface, and the drainage surface 271 is used to guide the adhesive medium to flow into the dispensing slot 27, so as to reduce the difficulty of the process of filling the adhesive medium into the dispensing space 221, and reduce the manufacturing cost of the camera module 1.

As mentioned above, the light turning element 5 may be a prism, and at this time, the outer surface of the light turning element 5 includes the reflection surface 51, the light incident surface 52, the light emitting surface 53, the first side surface 54 and the second side surface 55, and it can be understood that the dispensing slot 27 may be disposed at least one of the edge region of the reflection surface 51, the edge region of the light incident surface 52, the edge region of the light emitting surface 53, the first side surface 54 and the second side surface 55, so as to prevent the bonding medium from blocking the light from propagating at the middle of the light incident surface 52 or the light emitting surface 53 or from generating a projection at the middle of the reflection surface 51 to affect the shooting quality of the camera module 1 while bonding the light turning element 5 and the housing 2 through the bonding medium.

Since the areas of the first side surface 54 and the second side surface 55 are larger than those of the edge area of the reflection surface 51, the edge area of the light incident surface 52, and the edge area of the light emitting surface 53, when the light redirecting element 5 is bonded to the housing 2 through at least one of the first side surface 54 and the second side surface 55, the bonding area between the light redirecting element 5 and the housing 2 is larger, and the bonding stability is better. Based on this, it is preferable that the dispensing slot 27 is disposed corresponding to at least one of the first side surface 54 and the second side surface 55, in other words, the dispensing slot 27 is disposed corresponding to the first side surface 54 or the second side surface 55, or the dispensing slot 27 may be plural, and of the dispensing slots 27, a part of the dispensing slot 27 is disposed corresponding to the first side surface 54, and the remaining part of the dispensing slot 27 is disposed corresponding to the second side surface 55.

As mentioned above, the accommodating space 22 may further include two second limiting portions 252, the two second limiting portions 252 may be disposed to protrude toward the first side surface 54 or the second side surface 55, or the two second limiting portions 252 may be disposed to protrude toward the first side surface 54 and the second side surface 55. Based on this, optionally, the dispensing grooves 27 may be disposed on one side of the second limiting portion 252 facing the light turning element 5 to be disposed corresponding to the first side surface 54 or the second side surface 55, or when there are two second limiting portions 252, the dispensing grooves 27 may be multiple, in the dispensing grooves 27, a part of the dispensing grooves 27 is disposed on the second limiting portion 252 facing the first side surface 54 and is located on one side of the second limiting portion 252 facing the first side surface 54 to be disposed corresponding to the first side surface 54, and the remaining part of the dispensing grooves 27 is disposed on the second limiting portion 252 facing the second side surface 55 and is located on one side of the second limiting portion 252 facing the second side surface 55 to be disposed corresponding to the second side surface 55.

As shown in fig. 8, as described above, the first limiting portion 251 and the second limiting portion 252 may be disposed at an interval, at this time, an interval between the first limiting portion 251 and the adjacent second limiting portion 252 may be formed as an overflow space 222 for accommodating a part of the bonding medium overflowing from the dispensing slot 27, and at this time, the first limiting portion 251 may also be used for blocking the bonding medium in the overflow space 222 from flowing to the middle of the reflective surface 51, so as to prevent the bonding medium from generating a projection in the middle of the reflective surface 51 and affecting the imaging quality of the imaging device.

As mentioned above, the end 25a of the first position-limiting portion 251 can be bent. Further, when the end 25a of the first position-limiting portion 251 is bent toward the opposite second position-limiting portion 252, that is, when the end 25a of the first position-limiting portion 251 adjacent to the second position-limiting portion 252 corresponding to the first side surface 54 is bent toward the second position-limiting portion 252 corresponding to the second side surface 55, or the end 25a of the first position-limiting portion 251 adjacent to the second position-limiting portion 252 corresponding to the second side surface 55 is bent toward the second position-limiting portion 252 corresponding to the first side surface 54, the glue overflow space 222 formed between the first position-limiting portion 251 and the adjacent second position-limiting portion 252 is larger, and can be used for accommodating more overflowing bonding medium.

Referring to fig. 4, 6 and 7, in order to enable the light to pass through the second side 21 of the housing 2 from the light diverting element 5 to the light sensing surface 40 of the chip component 4, in an alternative embodiment, the second side 21 may be provided with a second opening 210, the second opening 210 is communicated with the accommodating space 22, and the chip component 4 is connected to the second side 21 corresponding to the second opening 210, that is, the light can pass through the second side 21 by way of the opening. In another alternative embodiment, the second side 21 may be at least partially formed of a transparent material (e.g., transparent glass, plastic, etc.) so as to be at least partially transparent, and the chip assembly 4 is connected to the second side 21 corresponding to the transparent portion, so that light can pass through the second side 21. It is understood that, at this time, the chip assembly 4 is entirely located outside the accommodating space 22.

The structure of the housing part 2 will be further explained below taking the example of the second side 21 being provided with the second opening 210.

It will be appreciated that when the second side 21 is provided with the second opening 210, the light diverting element 5 can be mounted into the accommodating space 22 through the second opening 210, in other words, by providing the second opening 210, the mounting of the light diverting element 5 into the accommodating space 22 from the outside of the accommodating space 22 can be facilitated. In this embodiment, as shown in fig. 4, alternatively, the housing portion 2 may be provided with an alignment structure 211, the alignment structure 211 may be located on the second side 21, and the alignment structure 211 is used as a reference for aligning the light redirecting element 5 with the housing portion 2 or the chip module 4 with the housing portion 2, so that when the light redirecting element 5 is mounted on the housing portion 2 or when the chip module 4 is mounted on the housing portion 2, an automatic mounting device can identify and position the housing portion 2 through the alignment structure 211, so as to improve the automatic assembly accuracy of the light redirecting element 5 with the housing portion 2 or the chip module 4 with the housing portion 2.

Specifically, the alignment structure 211 may be a protrusion or a recess formed in a predetermined shape, and the predetermined shape may be a circle, a square, a bar, an oval, an L-shape, a cross, or an arrow. Further, the number of the alignment structures 211 may be multiple, and the plurality of alignment structures 211 are disposed at the housing portion 2 at intervals to provide positioning references from different positions of the housing portion 2, so that the automatic installation device can recognize and compare shapes and positions of the plurality of alignment structures 211 to more accurately position the housing portion 2, thereby further improving the installation accuracy.

For example, as shown in fig. 4, the alignment structure 211 is shown as four L-shaped recesses in fig. 4, the four alignment structures 211 are disposed on the second side 21 around the component disposing space 220, so that the automatic mounting apparatus can determine the position of the component disposing space 220 by recognizing the positions of the four alignment structures 211, thereby accurately placing the light redirecting element 5 in the component disposing space 220, and avoiding a phenomenon that the light redirecting element 5 is damaged due to the light redirecting element 5 colliding with the component limiting part 25 in the process of placing the light redirecting element 5 in the component disposing space 220 through the second opening 210, thereby improving the yield of the camera module 1 and reducing the manufacturing cost of the camera module 1.

With continued reference to fig. 4, 6 and 7, in some embodiments, the second side 21 of the housing portion 2 may further be provided with a connecting flange 212, and a side of the connecting flange 212 facing the chip component 4 is connected to the chip component 4, so that a larger space exists between the component disposing space 220 and the chip component 4 for accommodating a larger light redirecting component 5.

Optionally, one side of the connecting convex edge 212 facing the chip assembly 4 may be adhered to the chip assembly 4 by an adhesive material (e.g., black photosensitive adhesive) with a light-shielding property, so that a gap between the casing 2 and the chip assembly 4 can be filled with the adhesive material, and impurities such as water and dust can be prevented from entering the accommodating space 22, and on the other hand, the light-shielding property of the adhesive material can be utilized to prevent external light from entering the accommodating space 22, so as to improve the shooting quality of the camera module 1.

Referring to fig. 7 and 9, in some embodiments, the chip assembly 4 may include a substrate 41 and a photo sensor chip 42 disposed on a side of the substrate 41 facing the light diverting element 5, the substrate 41 is connected to the second side 21 of the housing 2 and covers the second opening 210, the photo sensor chip 42 has a photo-sensing surface 40, and the light sensing surface 40 of the light sensing chip 42 is disposed toward the light diverting element 5, the accommodating space 22 is formed between the substrate 41 and the housing portion 2, so that the photosensitive chip 42 is located in the accommodating space 22, on one hand, the photosensitive surface 40 of the photosensitive chip 42 can be located in the accommodating space 22, thereby, the housing 2 and the substrate 41 protect the photosensitive surface 40, and impurities such as water and dust are prevented from falling on the photosensitive surface 40, while the substrate 41 is directly connected to the accommodating space 22 and the space outside the housing 2, thereby facilitating electrical connection of the photosensitive chip 42 to the circuit located outside the housing portion 2 through the substrate 41. In addition, the substrate 41 is used for covering the second opening 210, and a cover body is not required to be additionally arranged for covering the second opening 210, so that the overall structure of the camera module 1 is more compact, and the volume is smaller.

It is understood that, in other embodiments, the second side 21 of the housing portion 2 may not be provided with the second opening 210, and the chip component 4 may be entirely located in the accommodating space 22, so that the chip component 4 is more fully protected by the housing portion 2, and impurities such as water and dust are prevented from falling on the chip component 4.

In some embodiments, the photosensitive chip 42 may include a chip body 420 and a transparent cover 421 stacked on the photosensitive surface 40 of the chip body 420, a side of the chip body 420 facing away from the transparent cover 421 is disposed toward the substrate 41, and a side of the chip body 420 facing toward the transparent cover 421 is disposed toward the light turning element 5, so that the photosensitive surface 40 of the chip body 420 can be protected by the transparent cover 421, and the photosensitive surface 40 is prevented from contacting air to generate chemical reactions such as oxidation, and impurities such as water and dust fall into the photosensitive surface 40 of the chip body 420, thereby prolonging the service life of the chip body 420.

In some embodiments, the substrate 41 may include, but is not limited to, at least one of a fiberglass board, a ceramic chip assembly 4, and a flexible circuit board to enable electrical connection to the chip body 420, such that the chip body 420 is electrically connected to control circuitry carried by the substrate 41, or to external control circuitry through the substrate 41. It can be understood that, when base plate 41 includes the flexible circuit board, base plate 41 still can include the stiffening plate, and the stiffening plate is through connecting in the one side that deviates from sensitization chip 42 of flexible circuit board to strengthen the structural strength of flexible circuit board through the stiffening plate, so that flexible circuit board is difficult for taking place deformation in the use, thereby avoid sensitization chip 42 to follow the deformation of flexible circuit board and take place the displacement in the use, lead to the condition that the image shooting quality of module 1 descends of making a video recording.
