Description

Camera module, resistance type photosensitive assembly and electronic equipment

Technical Field

The utility model relates to an optical imaging technology field especially relates to a module of making a video recording and hinder formula photosensitive assembly and electronic equipment.

Background

In recent years, electronic products, smart devices, and the like are increasingly developed toward being light, thin and high-performance, and the development trend of the electronic products and the smart devices puts more severe requirements on the size and the imaging capability of a camera module, which is one of standard configurations of the electronic products and the smart devices. However, as consumer demands for high-pixel and high-performance camera modules become higher and higher, the height of the camera modules is increasing. The reason is that the height of the lens of the camera module increases as the pixels of the camera module become higher, and the thickness of the package portion of the photo sensor chip is difficult to decrease. In particular, there is a principle in the optical design of lenses: the lens thickness ratio of the camera module has a minimum value to ensure the feasibility of an optical system, namely, the lens thickness has a certain numerical range when the size of a lens image surface of the camera module is given. In other words, the higher the pixels of the camera module, the larger the required image plane of the lens, and the higher the height of the lens.

Currently, in order to reduce the height of the camera module, the height of the lens in the camera module is usually reduced as much as possible. On one hand, the optical design can be optimized, the height of the optical system is designed to be the minimum value, on the other hand, the structure design of the lens barrel can be optimized, the lowest end of the lens barrel is flush with the lowest end of the lens group or higher than the lowest end of the lens group (namely, the last lens in the lens group protrudes out of the lowest end of the lens barrel), and therefore the height of the lens barrel limiting the height of the lens barrel is the minimum. In addition, in order to further reduce the height of the camera module, the back focus of the lens can be reduced to a certain extent through reasonable optical system design, so that the distance between the photosensitive chip and the lens is further reduced. To achieve this, the chip circuit board assembly is usually packaged by molding, and the lens holder for mounting the color filter and the lens is eliminated, and the color filter is directly mounted on the surface of the molding, so as to further reduce the height of the camera module.

However, this also brings new risks, for example, the elimination of the lens holder makes the distance between the lens barrel or the lens of the lens and the color filter closer, which helps to reduce the height of the camera module, but during the assembly process of the camera module or during the focusing or focusing process of the camera module, the lens of the camera module is likely to collide with the color filter, so that the color filter is broken, and the damage of the camera module is caused.

In order to reduce the height of the camera module, the conventional camera module usually uses an optical design to make the back focus of the lens shorter, and then uses an IOM (IR on Molding, filter element is above the mold) structure, i.e. the filter element is directly attached to the mold base, so as to reduce the thickness of the molded photosensitive assembly. Illustratively, as shown in fig. 1, a conventional camera module 1P generally includes a motor lens assembly 2P and a molded photosensitive assembly 3P. The molding photosensitive component 3P includes a molding base 31P, an imaging component 32P and a filter element 33P, wherein the molding base 31P is disposed to cover a portion of the imaging component 32P, the filter element 33P is directly attached to an upper surface of the molding base 31P, and the filter element 33P corresponds to a photosensitive path of the imaging component 32P. The motor lens assembly 2P includes a motor 21P and an optical lens 22P, wherein the optical lens 22P is locked inside the motor 21P, wherein the motor 21P is disposed on the upper surface of the mold base 31P of the mold photosensitive assembly 3P such that the optical lens 22P corresponds to the photosensitive path of the imaging assembly 32P, and the filter element 33P is located between the optical lens 22P and the imaging assembly 32P. In this way, when the motor 21P drives the optical lens 22P to move up and down, the optical lens 22P will move away from or close to the imaging assembly 32P to achieve focusing or focusing of the camera module 1P.

However, although the mold base 31P having a small thickness can be manufactured by a molding process so that the thickness of the mold photosensitive assembly 3P is reduced and thus the distance between the optical lens 22P of the motor lens assembly 2P and the imaging assembly 32P of the mold photosensitive assembly 3P is reduced, the filter element 33P can be generally attached only to the upper surface of the mold base 31P so that the distance between the filter element 33P and the optical lens 22P is small. Furthermore, in order to further reduce the height of the conventional camera module 1P, the back focus of the camera module 1P can be reduced to a certain extent by a reasonable optical system design, so that the distance between the optical lens 22P and the imaging component 32P can be further reduced, and the distance between the optical lens 22P and the filter element 33P is reduced. In this way, when the optical lens 22P is driven by the motor 21P to approach the imaging assembly 32P during focusing or focusing of the camera module 1P, the optical lens 22P is likely to collide with the filter element 33P, which may cause the filter element 33P to break or damage the optical lens 22P, and thus the reliability of the conventional camera module 1P is seriously affected.

In addition, since the bottom surface of the motor lens assembly is generally a flat surface, so that the corresponding motor attachment surface on the mold base is also a flat surface, and in order to place the filter in the short back focus camera module as much as possible, the corresponding filter attachment surface on the mold base is generally sunk as much as possible, but in order to reduce the height of the camera module, the height of the motor attachment surface on the mold base needs to be reduced, so the filter attachment surface on the mold base is generally only slightly lower than the attachment surface on the mold base corresponding to the motor. The height of the filter and the thickness of the adhesive layer make the upper surface of the filter still higher than the attachment surface of the motor, so that the risk of the filter being broken still exists. In other words, no matter the motor attachment surface on the mold base is higher than, flush with, or lower than the filter attachment surface on the mold base, there is a risk that the filter is hit by the optical lens, and therefore, a new module structure design is urgently needed to solve the above problems.

Referring to fig. 2 to 4B, a camera module according to an embodiment of the present invention is illustrated, wherein the camera module 1 includes a blocking photosensitive assembly 10 and at least one motor lens assembly 20, wherein the blocking photosensitive assembly 10 includes a molded photosensitive assembly 11 and a blocking structure 12. The molded photosensitive component 11 includes an imaging component 111, a molded base 112, and a filter element 113, wherein the molded base 112 covers a portion of the imaging component 111, wherein the molded base 112 has an optical window 1120, and the optical window 1120 of the molded base 112 corresponds to a photosensitive path of the imaging component 111; wherein the filter element 113 is correspondingly disposed on the light window 1120 of the mold base 112. Each of the motor-lens assemblies 20 includes a motor 21 and an optical lens 22, wherein the motor 21 is disposed on the resistive photosensitive assembly 10, and the optical lens 22 is disposed on the motor 21 in a driving manner to drive the optical lens 22 to approach or separate from the imaging assembly 111 of the molding photosensitive assembly 11 through the motor 21, wherein the optical lens 22 corresponds to the photosensitive path of the imaging assembly 111, and the filter element 113 is disposed between the imaging assembly 111 and the optical lens 22, so that external light passes through the optical lens 22, then passes through the filter element 113, and finally passes through the optical window 1120 of the molding base 112 to reach the imaging assembly 111 along the photosensitive path of the imaging assembly 111.

In particular, as shown in fig. 3 to 4B, the blocking structure 12 of the blocking photosensitive assembly 10 is disposed on the molding photosensitive assembly 11, and a blocking surface 1201 of the blocking structure 12 is higher than an upper surface 1131 of the filter element 113 of the molding photosensitive assembly 11; wherein the blocking surface 1201 of the blocking structure 12 corresponds to the optical lens 22 of the motor-lens assembly 20, so that when the optical lens 22 is driven by the motor 21 to approach the imaging assembly 111 of the molded photosensitive assembly 11, the blocking structure 12 can block the optical lens 22 from directly contacting the filter element 113, so as to prevent the optical lens 22 from colliding with the filter element 113, thereby effectively reducing the risk of the filter element 113 breaking due to collision.

In other words, since the blocking surface 1201 of the blocking structure 12 is higher than the upper surface 1131 of the filter element 113, and the blocking surface 1201 of the blocking structure 12 corresponds to the optical lens 22, when the optical lens 22 is driven to approach the imaging component 111, the optical lens 22 will contact the blocking surface of the blocking structure 12 before colliding with the filter element 113, so as to avoid the optical lens 22 directly colliding with the filter element 113, prevent the filter element 113 from being damaged due to collision, and contribute to improving the reliability of the camera module 1.

It is noted that in this embodiment of the present invention, as shown in fig. 4A, the blocking surface 1201 of the blocking structure 12 may be, but is not limited to, implemented as the top surface of the blocking structure 12 to block the optical lens 22 through the top surface of the blocking structure 12 to prevent the optical lens 22 from directly contacting the filter element 113. Of course, in other examples of the present invention, the blocking surface 1201 of the blocking structure 112 may also be implemented as the side wall or other portion of the blocking structure 12, as long as it can block the optical lens 22 from contacting the filter element 113, so as to protect the filter element 113 from being collided by the optical lens 22, which is not described in detail herein.

It should be noted that although the features and advantages of the camera module 1 of the present invention are illustrated in fig. 2 to 4B and described below by taking the camera module 1 as an example, the camera module 1 includes only one motor lens assembly 20, it can be understood by those skilled in the art that the camera module 1 disclosed in fig. 2 to 4B and described below is only an example and does not limit the content and scope of the present invention, for example, in other examples of the camera module 1, the number of the motor lens assemblies 20 may be more than one to form an array type camera module.

It is noted that in this embodiment of the present invention, as shown in fig. 4A and 4B, the image forming assembly 111 of the molded photosensitive assembly 11 may include a photosensitive element 1111 and a circuit board 1112, wherein the photosensitive element 1111 is conductively connected to the circuit board 1112. It is understood that the photosensitive area of the photosensitive element 1111 of the imaging assembly 111 corresponds to the optical window 1120 of the mold base 112 to define the photosensitive path of the imaging assembly 111 through the photosensitive area of the photosensitive element 1111, so that the external optical beam passes through the optical lens 22 and the optical filter element 113 sequentially, and then passes through the optical window 1120 of the mold base 112 to reach the photosensitive area of the photosensitive element 1111 for being received by the photosensitive area of the photosensitive element 1111 for imaging.

Furthermore, in the camera module 1 according to the above embodiment of the present invention, the mold base 112 of the mold photosensitive assembly 11 of the resistive photosensitive assembly 10 can be wrapped around a portion of the photosensitive element 1111 and a portion of the circuit board 1112 of the imaging assembly 111 at the same time, so that the photosensitive element 1111 and the circuit board 1112 are integrated by the mold base 112, and the imaging assembly 111 forms an integrated structure. Of course, in other embodiments of the present invention, the mold base 112 may also be only partially covered on the circuit board 1112, and the photosensitive element 1111 is directly attached to the circuit board 1112, which is not further limited by the present invention.

According to the above embodiment of the present invention, as shown in fig. 2 and fig. 4A, the optical lens 22 of the motor lens assembly 20 of the camera module 1 further includes a lens barrel 221 and a lens group 222, wherein the lens group 222 is assembled to the lens barrel 221, and the lens barrel 221 is movably mounted to the motor 21, so that the motor 21 drives the lens barrel 221 to move up and down in the motor 21, so that the optical lens 22 can be close to or away from the imaging assembly 111 of the molded photosensitive assembly 11 of the blocking photosensitive assembly 10, so as to realize the focusing or focusing function of the camera module 1.

It should be noted that the resistive photosensitive assembly 10 of the present invention is very suitable for being adapted to the short back focal optical lens 22, so as to prevent the optical lens 22 from contacting and colliding with the filtering member 113 of the molding photosensitive assembly 11. Preferably, the optical lens 22 may be implemented, but is not limited to, having a back focus no greater than 0.6mm (i.e., the back focus of the optical lens 22 is less than or equal to 0.6 mm). Of course, in other examples of the present invention, the back focus of the optical lens 22 may be greater than 0.6 mm.

More preferably, as shown in fig. 4A, the blocking surface 1201 of the blocking structure 12 of the resistive photosensitive assembly 10 corresponds to the lens barrel 221 of the optical lens 22 of the motor lens assembly 20, so that when the optical lens 22 is driven to approach the imaging assembly 111, the blocking surface 1201 of the blocking structure 12 can contact with the lens barrel 221 of the optical lens 22, so that the blocking structure 12 prevents the optical lens 22 from colliding with the optical filter 113 by contacting with the lens barrel 221, so as to prevent the blocking structure 12 from colliding with the lens group 222 of the optical lens 22, thereby preventing the lens group 222 from being damaged due to collision of the blocking structure 12.

It is worth mentioning that, in some embodiments of the present invention, as shown in fig. 4A and 4B, in order to further reduce the height of the camera module 1, the optical lens 22 of the motor lens assembly 20 may further flush the lowest portion of the light emitting surface 2221 of the lens group 222 with the light emitting end surface 2211 of the lens barrel 221 through the optimized design of the lens barrel structure, or protrude the last lens of the lens group 222 from the light emitting end surface 2211 of the lens barrel 221 (that is, the lowest portion of the light emitting surface 2221 of the lens group 222 is lower than the light emitting end surface 2211 of the lens barrel 221), so as to minimize the height of the lens barrel 221 that limits the height of the optical lens 22. It can be understood that the light incident surface 2222 of the lens set 222 is opposite to the light emitting surface 2221 of the lens set 222, so that external light is firstly incident from the light incident surface 2222 of the lens set 222 and then exits from the light emitting surface 2221 of the lens set 222. Similarly, the light entrance end face 2212 of the lens barrel 221 is also opposite to the light exit end face 2211 of the lens barrel 221, the light entrance end face 2212 of the lens barrel 221 corresponds to the light entrance face 2222 of the lens group 222, and the light exit end face 2211 of the lens barrel 221 corresponds to the light exit face 2221 of the lens group 222.

However, once the height of the blocking structure 12 is insufficient, the structure of the optical lens 22 may still cause the lens group 222 of the optical lens 22 to collide with the filter chip 113, and therefore, in order to ensure that the blocking structure 12 can prevent any part of the optical lens 22 from colliding with the filter chip 113, in the camera module 1 of the present invention, as shown in fig. 4B, a distance h between the blocking surface 1201 of the blocking structure 12 of the camera module 1 and the light exit end surface 2211 of the lens barrel 221 is shown in fig. 4B₁Is smaller than the shortest distance h between the upper surface 1131 of the filter element 113 and the light exit surface 2221 of the lens group 222 of the optical lens 22₂(i.e. h)₁＜h₂) When the blocking surface 1201 of the blocking structure 12 contacts the light exit end surface 2211 of the lens barrel 221, a gap still exists between the light exit surface 2221 of the lens group 222 of the optical lens 22 and the upper surface 1131 of the optical filter element 113, so as to effectively prevent the optical lens 22 from colliding with the optical filter element 113. It can be understood thatIn other examples of the present invention, when the light emitting surface 2221 of the lens group 222 of the optical lens 22 is higher than the light emitting end surface 2211 of the lens barrel 221, the distance between the blocking surface 1201 of the blocking structure 12 and the light emitting end surface 2211 of the lens barrel 221 is necessarily smaller than the distance between the upper surface 1131 of the optical filter element 113 and the light emitting surface 2221 of the lens group 222 of the optical lens 22.

It should be noted that, in the above embodiment of the present invention, as shown in fig. 4A and 4B, the filter element 113 of the molding photosensitive assembly 11 of the resistive photosensitive assembly 10 of the camera module 1 is mounted on the molding base 112, wherein the blocking structure 12 is correspondingly disposed on a portion of the molding base 112 outside the filter element 113, so that no contact occurs between the blocking structure 12 and the filter element 113. In this way, when the optical lens 22 contacts or collides with the barrier structure 12, the filter element 113 is not subjected to any external force applied from the optical lens 22 or/and the barrier structure 12, so as to protect the filter element 113 from damage.

Preferably, as shown in fig. 4B, the blocking structure 12 of the blocking photosensitive component 11 extends upward from the surface of the mold base 112, so that the blocking surface 1201 of the blocking structure 12 is higher than the upper surface 1131 of the filter element 113, so as to prevent the optical lens 22 from striking the filter element 113 through the blocking structure 12. In other words, the blocking structure 12 of the blocking type photosensitive assembly 11 extends from the surface of the mold base 112 toward the lens barrel 221 of the optical lens 22, so that the blocking surface 1201 of the blocking structure 12 is higher than the upper surface 1131 of the optical filter 113, that is, the distance between the blocking surface 1201 of the blocking structure 12 and the light exit surface 2211 of the lens barrel 221 is smaller than the distance between the upper surface 1131 of the optical filter 113 and the light exit surface 2221 of the lens group 222 of the optical lens 22, so as to prevent any part of the optical lens 22 from contacting or striking the optical filter 113.

Further, in this embodiment of the present invention, the blocking structure 12 of the blocking type photosensitive assembly 11 may be, but is not limited to, separately disposed on the molding base 112 by means of adhesion, that is, the bottom surface of the blocking structure 12 and the surface of the molding base 112 are adhered by an adhesive, so that the blocking structure 12 is mounted on the molding base 112 as a separate component. Therefore, on the basis of not changing the original structure of the existing camera module, the existing camera module can be modified into the camera module 1 only by correspondingly installing the blocking structure 12 on the molding base so as to reduce the risk of collision and crack of the filter element. It is understood that, in other examples of the present invention, the blocking structure 12 may also be installed on the mold base 112 by means of, for example, clamping, embedding, welding, or screwing, etc., only by ensuring that the blocking surface 1201 of the blocking structure 12 is higher than the upper surface 1131 of the optical filter element 113, and the blocking surface 1201 of the blocking structure 12 corresponds to the optical lens 11, which is not described in detail herein.

More preferably, as shown in fig. 3 and 4A, the blocking structure 12 may include at least one strip-shaped protrusion 121, wherein each strip-shaped protrusion 121 is mounted on the mold base 112, and each strip-shaped protrusion 121 extends along an edge of the filter element 113 to form a linear protrusion on the mold base 112, so as to increase a contact area between the blocking structure 12 and the lens barrel 221 of the optical lens 22, help to reduce the impact strength of the blocking structure 12 on the optical lens 22, and help to protect the optical lens 22.

It is worth mentioning that for most camera modules, the optical lens typically has a circular cross-section, while the filter element typically has a rectangular cross-section, that is, in the camera module 1, the optical lens 22 of the motor lens assembly 20 has a circular cross section, and the filter element 113 of the molded photosensitive member 11 has a rectangular cross section, and therefore, in this embodiment of the present invention, the strip-shaped protrusions 121 of the blocking structure 12 preferably extend along the long edge of the filter element 113, i.e. one end of the strip-shaped protrusion 121 extends along the long edge of the filter element 113, so as to form a linear protrusion on the mold base 112, so that the upper side of the bar-shaped protrusion 121 serves as the blocking surface 1201 of the blocking structure 12, in order to further increase the contact area between the blocking structure 12 and the optical lens 22.

Illustratively, as shown in fig. 3, the blocking structure 12 includes two strip-shaped protrusions 121, wherein the two strip-shaped protrusions 121 are symmetrically disposed outside two long edges of the filter element 113, respectively, and each strip-shaped protrusion 121 extends from one short edge of the filter element 113 to the other short edge of the filter element 113 along the long edge of the filter element 113, so that the two strip-shaped protrusions 121 can simultaneously contact the optical lens 22, thereby facilitating to share the collision force generated between the optical lens 22 and the blocking structure 12, and reducing the risk of collision between the optical lens 22 and the color filter element 113 due to lens inclination. Of course, in other examples of the present invention, the blocking structure 12 may also only include one or more of the strip-shaped protruding members 121, for example, a plurality of the strip-shaped protruding members 121 may be disposed at intervals outside the same long edge of the filter element 113, and may also be disposed outside the long edge and the short edge of the filter element 113, only needing to ensure that the strip-shaped protruding members 121 can correspond to the optical lens 22, so as to block the optical lens 22 from colliding with the filter element 113, which is not described in detail herein.

It is noted that, in order to ensure that the blocking structure 12 can protect the filter element 113 from collision by blocking the lens barrel 221 of the optical lens 22, i.e. the blocking surface 1201 of the blocking structure 12 can correspond to the lens barrel 221 of the optical lens 22, as shown in fig. 4B, the strip-shaped protrusion 121 of the blocking structure 12 of the present invention can be, but is not limited to, implemented as a protrusion with a rectangular cross section, and the distance d between the inner side surface of the strip-shaped protrusion 121 and the optical axis 220 of the optical lens 22₁PreferablySmaller than the outer radius R (i.e., d) of the lens barrel 221 of the optical lens 22₁< R). In other words, the distance between the inner edges of the two symmetrically arranged bar-shaped protrusions 121 is smaller than the outer diameter of the lens barrel 221.

Further, as shown in fig. 4B, a distance d between an outer side surface of the bar-shaped protrusion 121 of the blocking structure 12 and the optical axis 220 of the optical lens 22₂Larger than the inner radius r (i.e., d) of the lens barrel 221 of the optical lens 22₂R), that is, the outer edge distance between the two bar-shaped convex parts 121 is larger than the inner diameter of the lens barrel 221, so as to ensure that the bar-shaped convex parts 121 of the barrier structure 12 at least correspond to the lens barrel 221 of the optical lens 22.

Further, in order to ensure that the blocking structure 12 can prevent the blocking structure 12 from contacting or striking the lens group 222 of the optical lens 22 while blocking the optical lens 22 from striking the filter element 113, so as to protect the lens group 222 of the optical lens 22 from being collided, as shown in fig. 4B, a distance d between the outer side surface of the strip-shaped protrusion 121 of the blocking structure 12 and the optical axis 220 of the optical lens 22 is shown in the present invention₂Smaller than the outer radius R (i.e., d) of the lens barrel 221 of the optical lens 22₂< R) so that the blocking surface 1201 of the blocking structure 12 is not exposed outside the light exit end surface 2211 of the lens barrel 221, so as to reserve enough installation space for the motor 21 on the mold base 112, and effectively avoid the blocking structure 12 from interfering with the assembly between the motor lens assembly 20 and the mold base 112.

More preferably, as shown in fig. 4B, a distance d between the inner side surface of the bar-shaped convex part 121 of the barrier structure 12 and the optical axis 220 of the optical lens 22₁Not smaller than the inner radius r (i.e., d) of the lens barrel 221 of the optical lens 22₁R) to avoid the contact or collision of the bar-shaped protrusion 121 with the lens set 222.

Furthermore, in this embodiment of the present invention, in order to alleviate the collision between the barrier structure 12 and the optical lens 22, the bar-shaped protrusion 121 of the barrier structure 12 may be, but is not limited to be, made of an elastic material such as rubber, silicone, or elastic plastic, so that when the optical lens 22 collides with the barrier structure 12, the bar-shaped protrusion 121 can perform a buffering function by deforming, so as to reduce the collision strength between the barrier structure 12 and the optical lens 22, and facilitate protecting the optical lens 22 and/or the barrier structure 12.

It is noted that fig. 5A and 5B show a first variant embodiment of the blocking photosensitive element 10 of the camera module 1 according to the above embodiment of the present invention, wherein the bar-shaped protrusion 121 of the blocking structure 12 has a trapezoidal cross section, so that the area of the upper side of the bar-shaped protrusion 121 is smaller than the area of the lower side of the bar-shaped protrusion 121, that is, the area of the blocking surface 1201 of the blocking structure 12 is smaller than the area of the bottom surface of the blocking structure 12, so as to prevent the blocking surface 1201 of the blocking structure 12 from contacting or colliding with the lens set 222 of the optical lens 22, and at the same time, provide a large enough bonding area for the bar-shaped protrusion 121 of the blocking structure 12 to firmly bond the bar-shaped protrusion 121 to the mold base 112.

Further, in addition to that the top surface of the bar-shaped protrusion 121 may be implemented as the blocking surface 1201, the side of the bar-shaped protrusion 121 higher than the upper surface 1131 of the filter element 113 may also be implemented as the blocking surface 1201. Exemplarily, as shown in fig. 5B, a dashed line partially shows a projection 2211 'of the light-emitting end face 2211 of the lens barrel 221 of the optical lens 22 on the molding photosensitive assembly 11, so in order to ensure that the blocking face 1201 can block the optical lens 22 from directly contacting the filter element 113, a projection 2211' of the light-emitting end face 2211 of the lens barrel 221 of the optical lens 22 on the molding photosensitive assembly 11 has an overlapping portion with a projection of the blocking face 1201 of the blocking structure 12 on the molding photosensitive assembly 11. In other words, as shown in fig. 5A, the plane where the upper surface 1131 of the filter element 113 is located intersects with the inner side surface of the bar-shaped protrusion 121 of the blocking structure 12 at a line P, then in order to ensure that the blocking surface 1201 can block the optical lens 22 from directly contacting with the filter element 113, a straight line where a projection P 'of the line P on the molding photosensitive assembly 11 is located must intersect with an arc line where an outer edge of a projection 2211' of the light-exit end face 2211 on the molding photosensitive assembly 11 of the lens barrel 221 is located, that is, a vertical distance between the projection P 'of the line P and a center of the projection 2211' of the light-exit end face 2211 is smaller than an outer diameter of the light-exit end face 2211 of the lens barrel 221.

Preferably, in order to avoid the contact between the blocking surface 1201 of the blocking structure 12 and the lens group 222 of the optical lens 22, an inner edge of the projection of the blocking surface 1201 of the blocking structure 12 on the molding photosensitive assembly 11 is located outside an inner edge of the projection 2211' of the light exit end surface 2211 of the lens barrel 221 on the molding photosensitive assembly 11. For example, a straight line on which a projection P 'of the line P on the molded photosensitive member 11 is located does not intersect with an arc on which an inner edge of the projection 2211' of the light exit end surface 2211 of the lens barrel 221 on the molded photosensitive member 11 is located.

More preferably, the strip-shaped protrusions 121 of the blocking structure 12 are symmetrically disposed outside the long side of the filter element 113. On the one hand, since the motor 21 generally has a square or square-like cross section, so that the circuit board 1112 of the imaging assembly 111 also has a square or square-like cross section, and the filter element 113 has a rectangular cross section like the photosensitive element 1111, the long side of the filter element 113 has a larger space for disposing the blocking structure 12; on the other hand, since the light exit end face 2211 of the lens barrel 221 of the optical lens 22 is generally circular, and the optical filter element 113 has a rectangular structure, so that the light exit end face 2211 of the lens barrel 221 is located right above the short side of the optical filter element 113, if the bar-shaped convex pieces 121 of the blocking structures 12 are arranged outside the short side of the optical filter element 113, it is difficult to block the optical lens 22, and therefore the bar-shaped convex pieces 121 of the blocking structures 12 are suitable for being arranged outside the long side of the optical filter element 113, so that the bar-shaped convex pieces 121 of the blocking structures 12 can effectively block the optical lens 22 from colliding with the optical filter element 113 when the optical lens 22 is tilted or focused and zoomed.

It is worth mentioning that in other examples of the present invention, the blocking structure 12 may also be implemented as a convex piece having a cross section such as an inverted L-shaped cross section or the like, such that the top surface of the blocking structure 12 is larger than the bottom surface of the blocking structure 12, i.e. the blocking surface 1201 of the blocking structure 12 is larger than the bottom surface of the blocking structure 12, so as to provide a larger installation space for the filter element 113 at the inner side of the blocking structure 12, which helps to improve the installation strength of the filter element 113. Of course, in other examples of the present invention, the bar-shaped protrusion 121 may also have a cross section with other shapes, such as a semi-circle, a trapezoid with rounded corners, or a triangle, as long as the optical lens 22 can be blocked from colliding with the filter element 113, and the present invention is not limited thereto.

Fig. 6A shows a second variant of the blocking photosensitive element 10 of the camera module 1 according to the above embodiment of the present invention, in which the blocking structure 12 only includes at least one column-shaped protrusion 122, wherein each column-shaped protrusion 122 extends upward from the surface of the mold base 112 to form a point-shaped protrusion on the mold base 112, that is, one end of the column-shaped protrusion 122 is connected to the surface of the mold base 112, and the other end of the column-shaped protrusion 122 extends toward a direction away from the mold base 112 (that is, close to the lens barrel 221 of the optical lens 22), so that the other end 1201 of the column-shaped protrusion 122 is higher than the upper surface 1131 of the filter element 113, that is, the end surface of the other end of the column-shaped protrusion 122 serves as the blocking surface 1201 of the blocking structure 12 to ensure that the blocking surface of the blocking structure 12 is higher than the upper surface 1131 of the filter element 113 So that the stud bump 122 can block the collision between the optical lens 22 and the filter element 113.

Thus, although the contact area between the stud bump 122 and the optical lens 22 is smaller than that of the bar bump 121, which is not favorable for reducing the collision strength between the stud bump 122 and the optical lens 22, the effective utilization area of the stud bump 122 per unit weight is greatly increased, which helps to reduce the weight of the barrier structure 12, thereby reducing the overall weight of the camera module 1, and reducing the possibility of interference between the barrier structure 12 and other structures in the camera module 1. In other words, since the optical lens 22 has a circular cross section and the filter element 113 has a rectangular cross section, only a part of the side surface of the bar-shaped protrusion 121 extending along the edge of the filter element 113 can correspond to the lens barrel 221 of the optical lens 22, and another part of the side surface of the bar-shaped protrusion 121 cannot contact the lens barrel 221, resulting in a reduction in the effective utilization area of the bar-shaped protrusion 121 per unit weight. The cylindrical protruding member 122 can be distributed at a reasonable position, so that the end surface of the cylindrical protruding member 122 completely corresponds to the lens barrel 221 of the optical lens 22, and the effective utilization area of the cylindrical protruding member 122 per unit weight is much larger than that of the bar-shaped protruding member 121.

Exemplarily, in this variant embodiment of the present invention, as shown in fig. 6A, the blocking structure 12 may include two of the columnar protrusions 122, wherein the two of the columnar protrusions 122 are symmetrically disposed outside two long edges of the filter element 113, respectively, and the columnar protrusions 122 correspond to the center of the long edge of the filter element 113, so as to ensure that the columnar protrusions 122 can completely correspond to the lens barrel 221 of the optical lens 22. Of course, in other examples of the present invention, the blocking structure 12 may also include four of the stud bumps 122, and each of the stud bumps 122 corresponds to a central position of an edge of the filter element 113. It is understood that the number of the pillar-shaped protrusions 122 in the blocking structure 12 may be any number, and the positions of the pillar-shaped protrusions 122 may also be arranged at any positions on the mold base 112, as long as it is ensured that the pillar-shaped protrusions 122 can block the optical lens 22 from colliding with the filter element 113, which is not described in detail herein.

It should be noted that, since the contact area between the stud bump 122 and the optical lens 22 becomes smaller, in order to alleviate the collision force between the stud bump 122 and the optical lens 22, the stud bump 122 of the present invention may be made of, but not limited to, an elastic material such as rubber. Of course, in other examples of the present invention, the pillar-shaped protrusion 122 of the blocking structure 12 may also be implemented as an elastic element having an elastic structure, such as a spring, so as to block the collision of the optical lens 22 with the filter element 113, and simultaneously alleviate the impact force between the optical lens 22 and the blocking structure 12 when the collision is blocked.

Fig. 6B shows a third variant of the resistive photosensitive element 10 of the camera module 1 according to the above embodiment of the present invention, wherein the blocking structure 12 comprises two of the strip-shaped protrusions 121 and two of the columnar protrusions 122, wherein the strip-shaped protrusions 121 are symmetrically disposed outside the long edge of the filter element 113 and extend along the long edge of the filter element 113 to form a linear protrusion on the mold base 112; wherein the pillar-shaped protrusion 122 is symmetrically disposed outside the short edge of the filter element 113 and corresponds to the center of the short edge of the filter element 113 to form a dot-shaped protrusion on the mold base 112, so that the blocking structure 12 can combine the advantages of the bar-shaped protrusion 121 (e.g., a linear protrusion) and the pillar-shaped protrusion 122 (e.g., a dot-shaped protrusion) to further stably block the collision between the optical lens 22 and the filter element 113.

Fig. 7A shows a first variant of the camera module 1 according to the above-described embodiment of the invention. Compared with the above-mentioned embodiment according to the present invention, the difference of the camera module 1 in this variant embodiment is: the blocking structure 12 of the blocking type photosensitive assembly 10 is integrally disposed on the molding base 112 of the molding photosensitive assembly 11, that is, the blocking structure 12 and the molding base 112 are integrally formed by molding, which not only enables the blocking structure 12 and the module base 112 to be firmly connected, but also helps to simplify the assembly process of the blocking type photosensitive assembly 10. In this way, after the resistive photosensitive element 10 is assembled, the assembly of the camera module 1 can be completed by directly mounting the motor 21 of the assembled motor-lens assembly 20 on the mold base 112.

Illustratively, as shown in fig. 7A, the bar-shaped protrusion 121 of the blocking structure 12 integrally extends upward from the mold base 112 to integrally form a linear protrusion on the surface of the mold base 112, and the bar-shaped protrusion 121 corresponds to the optical lens 22 to effectively block the optical lens 22 from colliding with the filter element 113 through the bar-shaped protrusion 121. Of course, in other examples of the present invention, the blocking structure 12 may further include the pillar protrusion 122, wherein the pillar protrusion 122 integrally extends upward from the mold base 112 to integrally form a dot protrusion on the surface of the mold base 112, which can also block the optical lens 22 from colliding with the filter element 113. It will be appreciated that when the blocking structure is integrally formed on the mold base 112 by a molding process, the blocking structure is preferably implemented as a strip-shaped protrusion, because the molding material is heated to become a fluid, which is easier to form and fill the mold cavity corresponding to the strip shape when the mold is filled with the molding material.

It is worth noting that in this variant embodiment of the invention, the bar-shaped protrusions 121 of the barrier structure 12 preferably have an isosceles trapezoidal cross section, so that the area of the upper side of the bar-shaped protrusions 121 is smaller than the area of the lower side of the bar-shaped protrusions 121, to facilitate the drawing operation during the molding process. In other words, the inner side surface of the protruding bar 121 extends obliquely outward from bottom to top, and the outer side surface of the protruding bar 121 extends obliquely inward from bottom to top, so that a certain draft angle is reserved on both the inner side and the outer side of the protruding bar 121, thereby facilitating the draft operation after molding. Of course, in other examples of the present invention, the bar protrusion 121 may have a cross section having other shapes such as a rectangle, a right trapezoid, a triangle, a semicircle, or a convex character, as long as a negative angle is not formed at both the inside and outside of the bar protrusion 121.

It is worth mentioning that the strip-shaped convex parts 121 (or the column-shaped convex parts 122) of the barrier structure 12 made by molding lack elasticity due to the molding material generally having a strong hardness after molding, which causes the strip-shaped convex parts 121 of the barrier structure 12 to generate a large impact force when colliding with the optical lens 22, thereby easily damaging the optical lens 22. Therefore, in order to alleviate the impact between the bar protrusion 121 and the optical lens 22 of the barrier structure 12, as shown in fig. 7A, the barrier structure 12 of the present invention may further include a buffer layer 123, wherein the buffer layer 123 is made of an elastic material such as plastic, silicon, and the like, and the buffer layer 123 is disposed on the upper side of the bar protrusion 121, so that when the barrier structure 12 collides with the optical lens 22, the buffer layer 123 is located between the bar protrusion 121 and the optical lens 22, so as to alleviate the collision between the barrier structure 12 and the optical lens 22 through the elastic deformation of the buffer layer 123, so as to reduce the impact strength between the barrier structure 12 and the optical lens 22, and help to protect the optical lens 22 and the bar protrusion 121. In other words, the buffer layer 123 of the barrier structure 12 is disposed on the upper side of the protruding bar 121 to provide the barrier surface 1201 of the barrier structure 12 through the upper surface of the buffer layer 123, so that the barrier structure 12 not only has the effect of preventing the optical lens 22 from colliding with the filter element 113, but also can play a role of buffering between the optical lens 22 and the protruding bar 121 of the barrier structure 12.

Of course, in other examples of the present invention, the buffer layer 123 of the blocking structure 12 may also be disposed on the light-emitting end face 2211 of the lens barrel 221 of the optical lens 22, so that when the blocking structure 12 collides with the optical lens 22, the buffer layer 123 is still between the strip-shaped convex part 121 and the lens barrel 221 of the optical lens 22, and can also play a role in reducing the impact strength between the blocking structure 12 and the optical lens 22.

Fig. 7B shows a second variant of the camera module 1 according to the above-described embodiment of the invention. Compared with the first variant embodiment according to the present invention, the camera module 1 according to the second variant embodiment differs in that: the motor 21 of the motor lens assembly 20 is directly mounted on the blocking surface 1201 of the blocking structure 12 of the resistive photosensitive assembly 10, that is, the motor 21 is directly mounted on the upper surface of the strip-shaped protrusion 121 of the blocking structure 12, so that the blocking structure 12 can provide a mounting base for the motor 21 of the motor lens assembly 20 while blocking the optical lens 22 from colliding with the filter element 113. In other words, the distance between the outer side surface of the bar-shaped protrusion 121 of the blocking structure 12 and the optical axis 220 of the optical lens 22 is greater than the outer radius of the lens barrel 221 of the optical lens 22, so that a part of the blocking surface 1201 of the blocking structure 12 is exposed out of the light exit end surface 2211 of the lens barrel 221 for mounting the motor 21.

Fig. 7C shows a third variant of the camera module 1 according to the above-described embodiment of the invention. Compared with the first variant embodiment according to the present invention, the camera module 1 according to the third variant embodiment differs in that: the molded photosensitive component 11 of the blocking photosensitive component 10 may further include a mounting bracket 114, wherein the mounting bracket 114 is disposed on the molded base 112, and the filter element 113 is correspondingly mounted on the mounting bracket 114, so that the filter element 113 is located at the optical window 1120 of the module base 112. It is understood that, under the action of the mounting bracket 114, the filter element 113 with a size smaller than the optical window 1120 can be correspondingly disposed on the optical window 1120 of the module base 112. In addition, the blocking photosensitive assembly 10 can also mount the filter element 113 at a position below the surface of the mold base 112 through the mounting bracket 114, which is helpful for reducing the distance between the upper surface 1131 of the filter element 113 and the imaging assembly 111, so that the height of the blocking structure 12 is reduced, which is convenient for further reducing the height of the camera module 1.

Fig. 7D shows a fourth variant of the camera module 1 according to the above-described embodiment of the invention. Compared with the third variant embodiment according to the present invention, the fourth variant embodiment according to the present invention differs from the camera module 1 in that: the blocking structure 12 of the blocking photosensitive assembly 10 is disposed on the mounting bracket 114 of the molding photosensitive assembly 11, so that the mounting bracket 114 and the blocking structure 12 combine to form a blocking mounting bracket, which helps to further reduce the height of the blocking structure 12. Furthermore, since the blocking structure 12 is directly provided to the mounting bracket 114, so that the area of the module base 112 on which the mounting bracket 114 is mounted becomes large, the mounting bracket 114 can be more firmly mounted to the mold base 112 to improve the internal structural strength of the camera module 1.

Exemplarily, in this variant embodiment of the present invention, as shown in fig. 7D, the blocking structure 12 includes two bar-shaped protrusions 121, wherein the bar-shaped protrusions 121 are integrally formed on the mounting bracket 114, and the bar-shaped protrusions 121 are respectively located on two opposite sides of the optical filter element 113, so that the blocking structure 12 and the mounting bracket 114 form a blocking mounting bracket having an integral structure, so as to block the optical lens 22 from colliding with the optical filter element 113. Need not to adjust on a large scale current camera module's structure like this, only need with have block structure 12 installing support 114 replaces traditional installing support, just can change current camera module into camera module 1 helps reducing camera module's repacking cost. Of course, in other examples of the present invention, the bar-shaped protrusion 121 of the blocking structure 12 can also be bonded to the mounting bracket 114, so that the blocking structure 12 and the mounting bracket 114 form a blocking mounting bracket with a split structure, so that there is no need to replace any existing structure of the existing camera module, and only the blocking structure 12 needs to be disposed on the mounting bracket of the existing camera module, thereby further reducing the modification cost of the camera module.

In addition, in other embodiments of the present invention, the motor 21 of the motor lens assembly 20 may also be directly mounted on the mounting bracket 114 of the molded photosensitive assembly 11 to maximize the mounting area between the mounting bracket 114 and the molded base 112, so that the mounting bracket 114 and the molded base 112 are more firmly connected.

Fig. 7E shows a fifth variant of the camera module 1 according to the above-described embodiment of the invention. Compared with the above embodiments according to the present invention, the difference between the camera module 1 according to the fifth variant embodiment is that: the blocking structure 12 of the blocking photosensitive assembly 10 is directly mounted to the edge region 1133 of the filter element 113 of the molding photosensitive assembly 11, wherein the blocking structure 12 is made of an elastic material such as silicone, rubber, etc., so as to alleviate the impact of the optical lens 22 on the filter element 113 through the elastic deformation of the blocking structure 12, so as to reduce the risk of cracking of the filter element 113. It is understood that the filter element 113 generally includes an edge region 1133 and a filter region 1134, wherein the edge region 1133 is located at the periphery of the filter region 1134, wherein the edge region 1133 of the filter element 113 can be directly attached to the mold base 112 to mount the filter element 113 to the mold base 112, so that the filter region 1134 of the filter element 113 corresponds to the light window 1120 of the mold base 112.

Illustratively, as shown in fig. 7E, the blocking structure 12 includes two strip-shaped protrusions 121 having elasticity, wherein the strip-shaped protrusions 121 respectively extend along long edges of the filter element 113 to form linear protrusions in edge regions of the filter element 113, so as to play a role of buffering between the filter element 113 and the optical lens 22 to prevent the filter element 113 from being cracked or chipped. In this way, since the blocking structure 12 is directly located on the filter element 113, the blocking structure 12 is always located between the filter element 113 and the optical lens 22, and therefore the blocking structure 12 can achieve a good anti-collision effect at a very small height. In particular, the blocking structure 12 may be, but is not limited to being, implemented as a layer of silicone gel attached to the edge region 1133 of the filter element 113 in order to maximize the cushioning capacity of the blocking structure 12.

It should be noted that, in other embodiments of the present invention, the blocking structure 12 may also be correspondingly disposed on the lens barrel 221, and the blocking structure 12 corresponds to the molding base 112 of the molding photosensitive assembly 11, so that when the optical lens 22 is driven to approach the imaging assembly 111, the blocking structure 12 contacts the molding base 112 before the optical lens 22 contacts the filter element 113, so as to block the optical lens 22 from hitting the filter element 113, thereby effectively reducing the risk of cracking or breaking the filter element 113.

s110: correspondingly arranging a blocking structure 12 on a molded photosensitive component 11 to form a blocking photosensitive component 10, wherein a blocking surface 1201 of the blocking structure 12 is higher than an upper surface 1131 of a filter element 113 of the molded photosensitive component 11; and

s120: the at least one motor lens assembly 20 is correspondingly disposed on the resistive photosensitive assembly 10, such that the blocking surface 1201 of the blocking structure 12 corresponds to the optical lens 22 of the motor lens assembly 20, wherein when the optical lens 22 can be driven by the motor 21 of the motor lens assembly 20 to approach the imaging assembly 111 of the molded photosensitive assembly 11, the blocking structure 12 can prevent the optical lens 22 from directly contacting the filter element 113.

It is noted that, in the step S110 of an example of the present invention, the blocking structure 12 may be directly adhered to the molding base 112 of the molding photosensitive assembly 11, so as to separately mount the blocking structure 12 on the molding base 112.

Of course, in another example of the present invention, the blocking structure 12 may also be integrally formed on the molding base 112 of the molding photosensitive assembly 11, so as to integrally mount the blocking structure 12 on the molding base 112.
