Detailed Description
Technical solutions in embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. In the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a camera module according to an embodiment of the present disclosure. The present application provides a camera module 100. The camera module 100 is used for acquiring images. The camera module 100 provided by the embodiment of the application can be applied to electronic equipment. The electronic device can be a digital camera, a mobile phone, a tablet computer, an electronic reader, a notebook computer, a vehicle-mounted device, a wearable device and the like. In the embodiment of the present application, the camera module 100 is described as being applied to a mobile phone.
The camera module 100 includes a lens 1001, a circuit board 1002, a base 1003, and an image sensor (not shown). The base 1003 and the image sensor are mounted on the circuit board 1003. The lens 1001 is mounted on the side of the chassis 1003 remote from the circuit board 1001. The base 1003 is used to support the fixed lens 1001. The image sensor can be embedded on the circuit board 1002. As can be understood, external light enters from the lens 1001 and is finally imaged on the image sensor.
Referring to fig. 1 and 2 together, fig. 2 is a schematic cross-sectional view of the lens 1001 shown in fig. 1 in a first embodiment. The lens 1001 includes a lens 101 and a barrel 102. The lens 101 is mounted to the barrel 102. As shown in fig. 2, the number of the lenses 101 is plural. The lens barrel 102 has a cylindrical shape for light to pass through.
The lens barrel 102 includes a barrel body 21. The lens barrel body 21 is a hollow structure with openings at both ends. The lens barrel body 21 has a barrel wall. The wall of the lens barrel is surrounded to form an accommodating space 210. The accommodating space 210 is used for accommodating the lens 101. It should be noted that in this application "wall" does not refer to a single wall but to a structure having a thickness.
As shown in fig. 1, a lens 101 is mounted in a lens barrel 102. After entering the lens barrel 102 from the opening at one end of the lens barrel body 21, the light passes through the lens 101 and exits from the opening at the other end of the lens barrel body 21.
It can be understood that the reinforcing member 22 with higher strength is embedded in the lens barrel body 21 with lower strength, so that the strength of the lens barrel 102 (the lens barrel body 21 and the reinforcing member 22) is greater than that of the lens barrel body 21 without the reinforcing member 22 embedded therein. That is, when the reinforcement 22 is embedded inside the lens barrel body 21 and the strength of the reinforcement 22 is greater than that of the lens barrel body 21, the strength of the lens barrel 102 can be increased.
On the one hand, in the embodiment of the present application, the strength of the lens barrel 102 is improved by embedding the reinforcing member 22 with higher strength into the lens barrel body 21, so that a scene that the lens barrel 102 is deformed due to stress when the lens 101 is mounted on the lens barrel 102 is avoided, and the stability and yield of the lens 1001 are improved.
On the other hand, in the embodiment of the present application, the reinforcing member 22 is completely disposed inside the barrel wall of the barrel body 21, so the size of the lens 1001 is not increased by the structure of the reinforcing member 22, and the strength of the barrel 102 can be enhanced without increasing the size of the entire lens 1001 by the reinforcing member 22, which is beneficial to the miniaturization of the lens 1001.
In one embodiment, the lens barrel body 21 is made of plastic. The material of the reinforcing member 22 is metal. The plastic is a synthetic resin having a high molecular weight as a main component. In practice, suitable additives, such as plasticizers, stabilizers, flame retardants, lubricants, colorants, etc., can be added to the plastic. That is, the plastic can be a plastic (flexible) material that is formed by machining, or a rigid material that is formed by curing and crosslinking. It will be appreciated that the strength of metal is greater than that of plastic. The reinforcement 22 is a metal sheet. The metal sheet can enhance the strength of the lens barrel 102.
In the embodiment of the present application, the reinforcing member 22 is made of a metal material, so that the reinforcing member 22 can increase the strength of the lens barrel 102 without increasing the thickness of the lens barrel 102. In other embodiments, the material of the reinforcement 22 may be other materials with high density and high strength, such as metal. In this case, the strength of the material used for the reinforcing member 22 is greater than the strength of the material used for the lens barrel body 21.
In one embodiment, the reinforcement 22 is integrally formed. The lens barrel body 21 is integrally formed. Before the lens barrel body 21 is molded, the reinforcement 22 is placed in a mold cavity, and then the lens barrel 102 with the reinforcement 22 embedded inside the lens barrel body 21 is injection molded. It is understood that the reinforcement member 22 is formed integrally with the lens barrel body 21.
In the embodiment of the present application, the reinforcing member 22 is integrally formed, so that the reinforcing member 22 is conveniently fixed in the mold cavity, thereby improving the manufacturing efficiency of the lens barrel 102.
Referring to fig. 2 and fig. 3, fig. 3 is a schematic structural diagram of the lens barrel 102 shown in fig. 2. The lens barrel body 21 includes an outer surface 211 and an inner surface 212 which are opposite to each other. The outer surface 211 is a surface of the lens barrel body 21 facing away from the lens 101. The inner surface 212 is used to secure the lens 101. When the lens 101 is received in the receiving space 210, the inner surface 212 is located between the lens 101 and the stiffener 22. The reinforcement 22 is located between the inner surface 212 and the outer surface 211. The spacing between the outer surface 211 and the inner surface 212 is less than or equal to 0.25 millimeters.
It will be appreciated that the outer surface 211 and the inner surface 212 are opposite sides of the lens barrel wall. The spacing between the outer surface 211 and the inner surface 212 is less than or equal to 0.25 mm, i.e., the thickness of the lens barrel wall is less than or equal to 0.25 mm. As shown in fig. 2, since the outer surface 211 and the inner surface 212 of the lens barrel wall are not a plane, in this case, the distance between the outer surface 211 and the inner surface 212 is the minimum distance between the outer surface 211 and the inner surface 212. As shown in fig. 2, the thickness of the lens barrel wall is identified by D1.
It can be understood that, since the reinforcement 22 is embedded inside the lens barrel body 21, the distance between the outer surface 211 and the inner surface 212 is the thickness of the lens barrel body 21 and the thickness of the reinforcement 22. The spacing between the outer surface 211 and the inner surface 212 is less than or equal to 0.25 millimeters, i.e., the thickness of the barrel 102 is less than or equal to 0.25 millimeters.
In the embodiment of the present application, the thickness of the lens barrel 102 is less than or equal to 0.25 mm, so that the thickness of the lens barrel 102 is relatively thin, and the volume of the lens 1001 is relatively small, which is beneficial to miniaturizing the lens 1001 and the camera module 100.
On one hand, when the thickness of the simple lens barrel body 21 is less than or equal to 0.25 mm, the strength of the lens barrel body 21 is reduced, when the lens 101 is mounted on the lens barrel 102, the wall of the lens barrel is stressed, and if the strength of the wall of the lens barrel is not enough, the lens barrel 102 is easily deformed after being stressed, which affects the stability and yield of the lens 1001.
On the other hand, when the thickness of the simple lens barrel body 21 is less than or equal to 0.25 mm, the lens barrel body 21 is difficult to meet the requirement of injection molding, and the yield of the lens barrel body 21 is affected, in the present case, the reinforcing member 22 with higher strength is embedded in the lens barrel wall of the lens barrel body 21, so that the reinforcing member 22 can be used as a supporting member, the thinner lens barrel body 21 is made, and the thickness and the strength of the lens barrel 102 are made thinner and meet the requirement.
It can be understood that when the thickness of the lens barrel body 21 is greater than 0.25 mm, the reinforcing member 22 does not need to be additionally embedded in the lens barrel wall, so that the preparation process of the lens barrel 102 is saved, and the efficiency of preparing the lens barrel 102 is improved.
In one embodiment, the thickness of the reinforcement 22 is greater than or equal to 0.05 millimeters. As shown in fig. 3, the thickness of the reinforcement 22 is identified as D2. It will be appreciated that the thickness of the metrology cylinder wall is in the same direction as the thickness of the metrology enhancement 22. The thickness of the reinforcement 22 is greater than or equal to 0.05 millimeters, i.e., D1 is greater than or equal to 0.05 millimeters.
In the embodiment of the present application, the thickness of the reinforcing member 22 is greater than or equal to 0.05 mm, so as to avoid that the strength of the lens barrel 102 cannot be enhanced due to the too thin thickness of the reinforcing member 22, so that the strength of the lens barrel 102 is effectively enhanced by the reinforcing member 22, and the reliability of the lens 1001 is improved.
In one embodiment, the thickness of the reinforcement 22 is less than or equal to 0.15 millimeters.
In the embodiment of the present application, the thickness of the reinforcing member 22 is less than or equal to 0.15 mm, so as to avoid the increase of the thickness and the mass of the lens barrel 102 due to the too thick reinforcing member 22, which is beneficial to the thinning of the lens 1001.
In the present embodiment, the thickness of the reinforcing member 22 is described as being in the range of 0.05 mm to 0.15 mm. That is, the thickness of the reinforcement 22 is greater than or equal to 0.05 mm, and less than or equal to 0.15 mm.
In one embodiment, the reinforcement 22 is annular in shape. That is, the shape of the reinforcing member 22 is similar to the shape of the lens barrel body 21. When the lens 101 is accommodated in the accommodating space 210, the reinforcement member 22 surrounds the lens 101.
In the embodiment of the present application, the reinforcing member 22 is annular, so that the reinforcing member 22 can increase the strength of the lens barrel 102 in all directions, and when the lens 101 is accommodated in the accommodating space 210, the reinforcing member 22 surrounds the lens 101, so that the reinforcing member 22 can surround the periphery of the lens 101, thereby improving the reliability of the lens 1001. In other embodiments, the reinforcing member 22 may be embedded in different shapes according to the structure of the lens barrel body 21. That is, the shape of the reinforcing member 22 is not limited in the present application.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view of the lens 1001 shown in fig. 1 in a second embodiment. Most technical solutions in this embodiment that are the same as those in the first embodiment are not described again. It is understood that the lens 1001 provided in the second embodiment of the present application is different from the lens 1001 provided in the first embodiment in the lens barrel 102.
The barrel wall includes a first end 213 and a second end 214 arranged in the axial direction. The second end portion 214 is formed to be enlarged in diameter with respect to the first end portion 213. A reinforcement 22 is disposed in at least one of the first end 213 and the second end 214. It will be appreciated that the diameter of the second end 214 is greater than the diameter of the first end 213. In one embodiment, a stiffener 22 is disposed in the first end 213. In another embodiment, a reinforcement 22 is provided in the second end 214. In yet another embodiment, both the first end 213 and the second end 214 are provided with reinforcements 22.
As shown in fig. 4, reinforcement member 22 includes a first reinforcement member 221 and a second reinforcement member 222. First stiffener 221 is disposed within first end 213 and second stiffener 222 is disposed within second end 214. First reinforcement 221 is spaced apart from second reinforcement 222.
In the embodiment of the present application, the first reinforcement part 221 and the second reinforcement part 222 are disposed at an interval, that is, the reinforcement parts are independently disposed at the position where the strength of the lens 1001 needs to be increased, so that the plurality of reinforcement parts are independent from each other, thereby preventing the lens 1001 from being still provided with the reinforcement parts at the position where the strength of the lens 1001 does not need to be increased, and preventing the plurality of reinforcement parts from being too large as a whole, thereby facilitating the miniaturization and the lightness of the lens 1001.
The diameter of the second reinforcement 222 is larger than the diameter of the first reinforcement 221. As shown in fig. 4, the first reinforcement 221 is located at one side of the second reinforcement 222. The diameter of the ring formed by the enclosure of the first reinforcement 221 is smaller than the diameter of the ring formed by the enclosure of the second reinforcement 222. It is understood that the first end 213 is an end of the lens barrel 102 close to the object side, and the second end 214 is an end of the lens barrel 102 close to the image side.
After each lens barrel 102 is manufactured, the reliability of the lens barrel 102 needs to be analyzed. The module factory generally performs a lateral thrust test on the bottom of the lens barrel 102 to determine the reliability of the lens barrel 102. If the strength of the bottom of the lens barrel 102 is low, the lens barrel 102 may be damaged in the lateral thrust test.
In the embodiment of the present application, the first reinforcement member 221 is embedded in the first end 213 for fixing the lens 101, and the second reinforcement member 222 is also embedded in the second end 214 of the lateral thrust test area, so as to enhance the strength of the second end 214, prevent the lens barrel 102 from being damaged during the lateral thrust test of the lens barrel 102 in a module factory, and thus improve the yield of the lens barrel 102.
Referring to fig. 5, fig. 5 is a schematic cross-sectional view of the lens 1001 shown in fig. 1 in a third embodiment. Most technical solutions in this embodiment that are the same as those in the previous embodiment are not described again. It is to be understood that the lens 1001 provided in the third embodiment of the present application is different from the lens 1001 provided in the foregoing embodiment in the lens barrel 102.
The first end 213 includes a top wall 2131 and a side wall 2132. The top wall 2131 is a wall of the lens barrel body 21 close to the object side. The side walls 2132 are connected between the second end 214 and the top wall 2131. It is understood that the side walls 2132 extend in a first direction and the top wall 2131 extends in a second direction. The first direction and the second direction cross each other.
In one embodiment, the second direction is perpendicular to the first direction. As shown in fig. 5, the first direction is a longitudinal direction and the second direction is a transverse direction. In other embodiments, the angle formed by the first direction and the second direction may be any angle. It is understood that the first direction and the second direction can be perpendicular to each other, and can also be non-perpendicular. In the embodiments of the present application, the description is given taking the case where the first direction is perpendicular to the second direction.
The first reinforcement 221 includes a first portion 2211 and a second portion 2212. The first portion 2211 is located in the top wall 2131 and the second portion 2212 is located in the side wall 2132. It will be appreciated that the top wall 2131 and the side walls 2132 of the first end 213 are each provided with a reinforcing member 22. The first portion 2211 is integrally formed with the second portion 2212. In the embodiment of the present application, the top wall 2131 of the first end portion 213 is also provided with the reinforcing member 22, which can reinforce the strength of the top wall 2131 of the lens barrel 102.
It can be understood that, in the embodiment of the present application, the reinforcing member 22 is embedded in the top wall 2131, so that the top wall 2131 still has a certain strength when the thickness is relatively thin, and thus the thickness of the top wall 2131 can be appropriately reduced on the premise of ensuring the strength of the top wall 2131, the purpose of reducing the height of the lens barrel 102 is achieved, and the miniaturization of the lens 1001 is facilitated.
