Referring to fig. 2 and 3 of the drawings, a camera module according to a first preferred embodiment of the present invention is disclosed and explained in detail, wherein the camera module includes an optical lens 10, an integrated limit base 20, a circuit board 30 and a photosensitive chip 40 accommodated in the integrated limit base 20. The optical lens 10 is limited by the integrated limiting base 20 to fixedly hold the optical lens 10 and the photosensitive chip 40, wherein the photosensitive chip 40 accommodated in the integrated limiting base 20 can conductively receive the light of the optical lens 10. Further, the integrated limiting base 20 receives the optical lens 10 and the circuit board 30.

The integrated limiting base 20 has a light guide channel 200, and a receiving opening 201 and a receiving opening 202 for communicating the light guide channel 200 and the external space. The integrated limit mount 20 and the optical lens 10 are axially connected. The optical lens 10 is held in the socket 201 of the integrated limiting base 20 in an embedded manner, wherein the circuit board 30 is held in the accommodating port 202 of the integrated limiting base 20, wherein the photosensitive chip 40 is attached to the circuit board 30, wherein light transmitted by the optical lens 10 is vertically projected to the photosensitive chip 40, wherein the photosensitive chip 40 and the circuit board 30 are conductively connected, so that optical information of the photosensitive chip 40 is converted into an electrical signal and then received and processed by the circuit board 30 to form imaging information.

Further, the optical lens 10 is axially held by the integrated mount 20. The optical lens 10 includes a lens barrel 11 and at least one lens 12, wherein the lens barrel 11 has an accommodating space 110, and a light inlet 111 and a light outlet 112 communicating with the accommodating space 110, and one of the lenses 12 (i.e. the lens 12 held on the nearest image side) held on the light outlet 112 is directly supported by the integrated limiting base 20 to limit the lens 12 held on the lens barrel 11. In other words, the lens 12 is held between the lens barrel 11 and the integrated limit base 20 by the integrated limit base 20. Further, the lens 12 on the nearest object side is retained by the lens barrel 11 in a limited manner.

Referring to the first preferred example of the present invention, the lens 12 on the nearest object side is blocked by the most object side surface of the lens barrel 11 in the non-light-transmitting area.

Preferably, the lens 12 held to the most proximal image side is abutted by the integral stop block 20, wherein the proximal face 121 of the lens 12 is abutted by the integral stop block 20. It is worth mentioning that the integrated limiting base 20 is in planar fit with the image-approaching side surface 121 of the lens 12 so as to better fix the lens 12 and further improve the coaxiality of the optical axes of the photosensitive chip 40 and the lens 12.

Further, the image-near side surface 121 of the lens 12 is held at the light-exit port 112 of the lens barrel 11 in a manner of protruding from an image-near side surface of the lens barrel 11, wherein the integrated limiting base 20 directly abuts against the image-near side surface 121 of the lens 12, and an image-near side surface 115 of the lens barrel 11 and the integrated limiting base 20 are held at an interval, so that the lens 12 on the nearest image side is tightly attached by the integrated limiting base 20, thereby preventing light from entering the light path.

It should be noted that the image-near side 121 and an object-near side of the lens 12 are oppositely maintained, and the object side of the optical lens 10 is the side facing the external environment, wherein the image side of the optical lens 10 refers to the side facing the photosensitive chip 40.

Referring to a preferred example of the present invention, the number of the lenses 12 is 3, and the present invention is not limited by the number of the lenses 12, and the number of the lenses 12 may be 1, 2, 4, 5, 6, 7, 8 or 9, which can be understood and implemented by those skilled in the art.

Further, the optical lens 10 includes at least one spacer 13, and any adjacent lens 12 is spaced apart by the spacer 13. With reference to the first preferred example of the present invention, the number of said spacers 13 is two and is kept in any adjacent said non-light-transmitting area of said lens 12, so as to ensure that the light path of said lens 12 is not blocked.

Furthermore, the surface of any lens 12 can be concave, convex, crescent, free-form surface, and the like, and the utility model is not limited.

The lenses 12 are retained in the accommodating space 110 of the lens barrel 11 in an aligned manner, wherein the integrated limiting base 20 is fittingly mounted to the light outlet 112 of the lens barrel 11 to limit the accommodated lenses 12.

Referring to a preferred embodiment of the present invention, the integrated limit base 20 further has a base body 21, a limit end 22 and a connection seat 23. The limiting end 22 and the connecting seat 23 integrally extend from the base main body 21, wherein the base main body 21 has an annular sidewall and defines the receiving opening 202, and the limiting end 22 extends from the base main body 21 to the inside to define the light guide channel 200. The retainer 22 is retained on one side of the base body 21, wherein the connecting seat 23 extends axially from the retainer 22 to form an annular sidewall and define the socket 201. The optical lens 10 is inserted into the socket 201 of the connecting base 23 and is limited and locked by the limiting end 22 to directly limit the lens 12 accommodated in the lens barrel 11. The base body 21 is connected to the circuit board 30, and the circuit board 30 is held in the receiving opening 202 of the integrated limit base 20. Further, the photosensitive chip 40 is held between the circuit board 30 and the integrated positioning base 20.

Further, the light inlet 111 of the lens barrel 11 is conductively connected to the light guide channel 200 of the integrated limiting base 20. The light entering the lens barrel 11 is transmitted through the lens 12 in sequence and then projected to the photosensitive chip 40 from the light guide channel 200 of the integrated limiting base 20. That is, the light guide channel 200 of the integrated limiting base 20 does not affect the transmitted light of the optical lens 10. In other words, the integrated limiting base 20 directly receives a non-light-transmitting area of the lens 12 of the optical lens 10, and a light-transmitting area of the lens 12 is smaller than or equal to the light-guiding channel 200 of the integrated limiting base 20.

Further, the position-limiting end 22 has a light-passing sidewall 220, a near-object side surface 221 and a near-image side surface 222, wherein the near-object side surface 221 and the near-image side surface 222 of the position-limiting end 22 respectively extend radially from two ends of the light-passing sidewall 220 to form an annular ring with the light-guiding channel 200, wherein the near-object side surface 221 of the position-limiting end 22 is directly lower than the image side surface of the lens 12 held at the nearest image side. The object-proximal side surface 221 of the retaining end 22 is configured to be flat to better support the lens 12 held at the most image side of the optical lens 10, wherein a radial cross-sectional view of the retaining end 22 is a circular ring to keep the object-proximal side surface 221 of the retaining end 22 held at the non-light-transmitting area of the lens 12 to keep the light rays of the optical lens 10 unaffected.

Further, the image-near side surface 115 of the lens barrel 11 and the object-near side surface 221 of the limiting end 22 are held at intervals, and the lens 12 is directly held by the object-near side surface 221 of the limiting end 22 in a pressing manner through the lens 12, so as to fix the lens 12.

The object-near side surface 221 of the position-limiting end 22 is preferably a plane surface to snugly support the lens 12 accommodated in the lens barrel 11. In other examples, the object-near side surface 221 of the position-limiting end 22 may be an inclined surface or a rough surface to support the lens 12 accommodated in the lens barrel 11. Referring to the first preferred example of the present invention, the image-near side surface 115 of the lens barrel 11 and the object-near side surface 221 of the stopper 22 are held at intervals, and are connected by a screw only through the side wall of the lens barrel 11 and the side wall of the connection seat 23. That is, the lens 12 is fixed in a limited manner by the positioning connection of the lens barrel 11 and the connection holder 23.

The light-passing sidewalls 220 define the light-guiding channels 200. Referring to the first preferred example of the present invention, the light-passing sidewall 220 defines a "gradually-enlarged-opening" channel (i.e. the light-guiding channel 200), wherein the diameter of the through hole defined by the light-passing sidewall 220 on the near-object side is smaller than the diameter of the through hole defined by the light-passing sidewall 220 on the near-object side of the photosensitive chip 40. The light guide channel 200 with gradually enlarged opening can prevent the light transmitted by the lens 12 closest to the image side from being blocked by the light-passing sidewall 220 of the limiting end 22, so as to reduce the influence on the light.

The shape of any of the lenses 12 is not limited by the present invention. Even if the light rays transmitted by the lens 12 on the nearest image side are projected in a diffused manner, the light rays are not affected by the light-passing side wall 220, and meanwhile, the light-passing side wall 220 with the gradually-enlarged opening reduces stray light generated by reflected light rays, so that the image information of the camera module is further ensured to be clear and accurate.

The channel defined by the light-transmitting side wall 220 (i.e. the light-guiding channel 200) may have a constant opening size or a gradually enlarged opening with a certain arc surface.

Optionally, the light-transmitting side wall 220 is selected from the group of flat and rough types, and is not limited herein.

The base body 21 has an inner wall 210, wherein the inner wall of the base body 21 extends from the image-proximal side 222 of the limiting end 22 to define the receiving opening 202. That is, the base body 21, the retaining end 22 and the connecting seat 23 of the integrated retaining base 20 define the inner wall 210 of the base body 21, since the light-passing sidewall 220, the near-object side surface 221 and the near-image side surface 222 of the retaining end 22 and the inner wall 210 of the base body 21 extending from the near-image side surface 222 of the retaining end 22 are defined, since the light-passing sidewall 220, the near-object side surface 221 and the near-image side surface 222 of the retaining end 22 and the inner wall 210 of the base body 21 extending from the near-image side surface 222 of the retaining end 22 are all planes or inclined planes or non-flat planes. The image-near side surface 115 of the lens barrel 11 and the integrated limiting base 20 are maintained at intervals, so that the lens 12 on the nearest image side is tightly attached by the integrated limiting base 20, dust prevention is achieved, the lens 12 is prevented from loosening, and imaging quality is guaranteed.

Further, the limiting end 22 extends radially from the axial end surface of the base main body 21 to define the receiving opening 202, wherein the image-proximal surface 222 of the limiting end 22 and the inner wall 210 of the base main body 21 extend straight. In other examples of the present invention, the image-proximal side 222 of the limiting end 22 and the inner wall 210 of the base main body 21 extend arcuately, and the present invention is not limited thereto.

Referring to fig. 2 of the drawings, the lens barrel 11 is embeddedly held on the integrated limiting base 20 to close the socket 201 of the integrated limiting base 20, wherein the lens 12 accommodated in the lens barrel 11 is held by the limiting end 22 of the integrated limiting base 20. That is, the integrated position-limiting base 20 is screwed to the lens barrel 11 and fixedly holds the lens 12, wherein no other fixing element is needed to fix the position of the lens 12, and at least one fixing element pressing the lens 12 is reduced from being connected and engaged with the lens barrel 11, so that the connection between the lens barrel 11 and the integrated position-limiting base 20 is smoother, thereby reducing the generation of stray light and preventing stray light from entering the optical path to affect the imaging effect.

Referring to the first preferred example of the present invention, the lens barrel 11 and the connection base 23 are threadedly connected, wherein the side wall of the connection base 23 has an internal thread, wherein the outer wall of the lens barrel 11 has an external thread, and the connection base 23 and the lens barrel 11 are adaptively and threadedly connected.

Further, the lens barrel 11 has a connecting portion, wherein the connecting base 23 has a connecting portion, wherein the connecting portion of the lens barrel 11 and the connecting portion of the connecting base 23 can be matched to limit to connect the lens barrel 11 and the integrated limiting base 20 in a limiting manner. Referring to the first preferred example of the present invention, the connecting portion of the lens barrel 11 and the connecting portion of the connecting base 23 are threads screwed to each other to be screwed fittingly. In other examples of the present invention, the connecting portion of the lens barrel 11 and the connecting portion of the connecting base 23 can also be implemented as other technical means to connect the lens barrel 11 and the integrated limiting base 20 in a limiting manner, which should be understood by those skilled in the art.

Referring to fig. 2 of the drawings, the circuit board 30 closes the receiving opening 202 in a manner of covering the base body 21 of the integrated limit base 20. That is, the position-limiting end 22 and the circuit board 30 are held by the base body 21 at intervals, wherein the photosensitive chip 40 is held between the circuit board 30 and the position-limiting end 22, so that the light transmitted by the optical lens 10 is projected from the light-guiding channel 200 to the photosensitive chip 40 held in the receiving opening 202.

Referring to the first preferred embodiment of the present invention, the circuit board 30 is attached to the end surface of the base body 21 to close the receiving opening 202. In other examples of the present invention, the circuit board 30 is connected to the end surface of the base main body 21 by a screw connection manner to close the receiving opening 202, and the present invention is not limited thereto. The type of shape of the circuit board 30 is not limited in any way.

Referring to a preferred example of the present invention, the photosensitive chip 40 is attachingly held on the circuit board 30, when the circuit board 30 is installed on the integrated limiting base 20, the photosensitive chip 40 is supportingly held on the circuit board 30 at the receiving opening 202 of the integrated limiting base 20 and receives the light transmitted by the optical lens 10.

Preferably, the circuit board 30 and the integrated limit base 20 can be connected in a fine adjustment manner to adjust the relative positions of the light paths of the photosensitive chip 40 and the optical lens 10.

In another example of the present invention, the photosensitive chip 40 is retained by the integral limiting base 20 in a limiting manner. That is, the photosensitive chip 40 and the circuit board 30 are held at intervals.

Further, the photosensitive chip 40 is connected to the integrated limiting base 20 in a fine-tuning manner, so as to adjust the relative position of the photosensitive chip 40 and the optical path of the optical lens 10. In this example, the photo chip 40 and the integrated limit base 20 can be mounted by means of clipping, gluing and a combination thereof, which will be understood and known by those skilled in the art.

Referring to fig. 2 of the drawings, a first preferred embodiment of the present invention is disclosed and explained in detail, wherein the integrated limit base 20 is in the form of a two-piece tubular shape. Since the optical lens 10 is cylindrical, the connection seat 23 of the integrated limiting seat 20 is cylindrical, wherein the connection seat 23 is annular. The light-transmitting sidewall 220 of the limiting end 22 of the integrated limiting base 20 is a circular sidewall to define a circular tube-shaped light-guiding channel 200. The base body 21 has a circular side wall. Further, the base body 21 is cylindrically represented.

Because the inner diameter of the connecting seat body 23 is smaller than the inner diameter of the seat main body 21, the integrated limit seat 20 is in a two-section round tube shape.

Referring to fig. 4 and 5 of the drawings, a second preferred example of the present invention is disclosed and explained in detail, wherein the connection housing 23 further has an extension body 231 and a fastening portion 232 formed in a radial direction of the extension body 231.

The light exit 112 of the optical lens 10 is held upward, wherein the locking portion 114 can be locked by the locking portion 232 of the integrated limiting base 20 in the process that the integrated limiting base 20 covers the lens barrel 11.

Preferably, the engaging portion 232 of the connection seat 23 extends inward from an end surface of the extension body 231. The locking portion 114 of the lens barrel 11 protrudes outward from the sidewall of the lens barrel main body 113, so that the locking portion 114 of the lens barrel 11 and the locking portion 232 of the connecting base 23 are locked and locked by each other.
