In the related art, the camera module 60 includes a lens and a lens barrel connected to each other. The lens and the lens cone are respectively and independently processed and manufactured. The finished lens and lens barrel need to be assembled. After the lens and the lens barrel are assembled, a connecting area is formed between the lens and the lens barrel. And glue is arranged in a gap between the lens and the lens barrel close to the light inlet part of the lens. The glue is arranged outside a connecting area formed by the lens and the lens barrel.

The following explains an implementation of the camera module 60 provided in the embodiment of the present application.

Fig. 3 schematically shows a partial structure of the camera module 60. Fig. 4 schematically shows a partially sectional structure of the camera module 60. Referring to fig. 3 and 4, the camera module 60 according to the embodiment of the present disclosure includes a lens 61. The lens 61 has a light incoming portion for receiving light. The camera module 60 further includes a lens barrel 62. The lens barrel 62 includes a center hole 621. The lens barrel 62 has opposite end faces in the axial direction of the center hole 621. The center hole 621 penetrates through opposite end surfaces of the lens barrel 62. In some examples, at least part of the lens 61 is located within the lens barrel 62. Illustratively, a portion of the lens 61 extends beyond the barrel 62, while the remainder of the lens 61 is located within the barrel 62.

Fig. 5 schematically shows a partial sectional structure of the lens 61. Referring to fig. 5, the lens 61 includes an outer connection portion 611 provided on an outer surface thereof. The outer connecting portion 611 of the lens 61 is used to achieve connection with the lens barrel 62. Fig. 6 schematically shows a partially sectional structure of the lens barrel 62. Referring to fig. 6, an inner connecting portion 622 is provided on an inner wall of the center hole 621 in the axial direction X of the center hole 621. In some examples, the inner connection portion 622 is provided in a middle area of the inner wall of the center hole 621 in the axial direction X of the center hole 621. The end surfaces of the lens barrel 62 are spaced apart from the inner connecting portion 622.

The outer connection portion 611 of the lens 61 is connected to the inner connection portion 622 of the lens barrel 62. When the lens 61 and the lens barrel 62 are assembled, the outer connecting portion 611 of the lens 61 may be gradually fitted into the center hole 621 of the lens barrel 62. Then, the outer connection portion 611 of the lens 61 is connected with the inner connection portion 622 of the lens barrel 62. Fig. 7 is an enlarged view of a portion a in fig. 4. Referring to fig. 4 and 7, a first receiving portion 60a may be formed on an inner wall of the center hole 621 between a region of the inner connecting portion 622 on a side facing the light entering portion and the lens 61. The first receiving portion 60a is located outside the connection region M formed by the outer connection portion 611 and the inner connection portion 622 in the axial direction X of the center hole 621.

Referring to fig. 7, the camera module 60 further includes a first connection paste 63. The first connection paste 63 is disposed between the outer connection portion 611 and the inner connection portion 622, so that the area of the first connection paste 63 exposed to the external environment is small. At least part of the outer connection part 611 and at least part of the inner connection part 622 are covered with the first connection paste 63. In some examples, the first connection glue 63 completely covers the outer connection portion 611 and the inner connection portion 622 along the axial direction X of the central hole 621. The lens 61 and the lens barrel 62 are respectively connected with the first connection paste 63, so that the first connection paste 63 is beneficial to improving the connection stability of the lens 61 and the lens barrel 62. When the lens 61 is subjected to the torque, the first connection glue 63 can apply a reaction force to the lens 61, so that the lens 61 is not easy to rotate relative to the lens barrel 62, and the possibility of separation of the outer connection part 611 and the inner connection part 622 caused by the rotation of the lens 61 is reduced.

Referring to fig. 4 and 7, the camera module 60 further includes a second connection paste 64. The second connection paste 64 is disposed in the first receiving portion 60a. The second connection paste 64 connects the lens 61 and the lens barrel 62. The second connection paste 64 is located on a side of the first connection paste 63 facing the light intake portion in the axial direction X of the center hole 621. The second connection paste 64 is positioned at one side of the connection region M formed by the outer connection parts 611 and the inner connection parts 622. The second connection paste 64 covers the first connection paste 63, which is beneficial to further reducing the area of the region of the first connection paste 63 exposed to the external environment. In some examples, the first connection paste 63 and the second connection paste 64 are connected. When the lens 61 is subjected to the torque, the second connection glue 64 can also apply a reaction force to the lens 61, so that the lens 61 is not easy to rotate relative to the lens barrel 62. The first connection paste 63 and the second connection paste 64 can jointly adhere the lens 61 and the lens barrel 62 to effectively fix the position of the lens 61 and improve the connection stability of the lens 61 and the lens barrel 62.

In the camera module 60 according to the embodiment of the present application, the lens 61 and the lens barrel 62 are connected by the outer connecting portion 611 and the inner connecting portion 622. A first connection paste 63 is disposed between the outer connection part 611 and the inner connection part 622, and a second connection paste 64 is disposed at one side of the first connection paste 63. The first connecting glue 63 and the second connecting glue 64 can fix the position of the lens 61, so that the connecting stability and reliability of the lens 61 and the lens barrel 62 are effectively improved, and the possibility that the lens 61 is loosened or falls off is reduced. Because the first connecting glue 63 is located between the outer connecting part 611 and the inner connecting part 622 and the second connecting glue 64 covers the first connecting glue 63, the area of the contact area between the first connecting glue 63 and the external environment is small, so that the first connecting glue 63 is not easy to age in advance, the possibility that the first connecting glue 63 cracks and fails in connection due to the fact that the first connecting glue 63 ages in advance is reduced, and the first connecting glue 63 can be ensured to play a role in fixing the position of the lens 61 for a long time.

In some implementations, the second connection paste 64 is an annular structure surrounding the lens 61. The second connection glue 64 can completely cover the first connection glue 63 at one side of the first connection glue 63, so that the area of the first connection glue 63 facing the light inlet portion is not in direct contact with the external environment, and the area of the contact area of the first connection glue 63 and the external environment is further reduced. In addition, the second connection glue 64 can connect the lens 61 and the lens barrel 62 in the whole circumferential direction of the lens 61, which is beneficial to increasing the connection area of the lens 61 and the second connection glue 64 and the connection area of the lens barrel 62 and the second connection glue 64, and further improving the connection strength of the lens 61 and the lens barrel 62.

In some realizable ways, fig. 8 schematically shows a partial cross-sectional structure of the camera module 60. Fig. 9 is an enlarged view of fig. 8 at B. Referring to fig. 8 and 9, the lens 61 includes an annular receiving groove 612 provided at an outer surface. The annular receiving groove 612 is disposed on a side of the outer connection portion 611 facing the light inlet portion. The first receiving portion 60a communicates with the annular receiving groove 612. A portion of the second connection paste 64 is positioned in the annular receiving groove 612. The second connection glue 64 can apply a constraint force along the axial direction X of the central hole 621 to the lens 61 through the part located in the annular accommodation groove 612, so that the impact resistance of the lens 61 is improved, and the possibility that the lens 61 moves along the axial direction X of the central hole 621 when the camera module 60 is subjected to an impact force is reduced. Correspondingly, when the camera module 60 receives an impact force, the second connection glue 64 can be constrained by the lens 61, so that the second connection glue 64 is not easy to move along the axial direction X of the central hole 621. In addition, the annular receiving groove 612 can receive a part of the second connection glue 64, so that the amount of the second connection glue 64 can be increased, and the possibility that the bonding strength of the second connection glue 64 is smaller due to the smaller amount of the second connection glue 64 is reduced. Moreover, the portion of the second connection glue 64 located in the annular receiving groove 612 is not directly exposed to the external environment, which is beneficial to reducing the area of the region of the second connection glue 64 exposed to the external environment, thereby being beneficial to reducing the possibility that the second connection glue 64 is easy to age.

In some examples, the annular receiving groove 612 is located within the central bore 621 of the lens barrel 62. The opening of the annular receiving groove 612 faces the inner wall of the center hole 621. The annular receiving groove 612 is located lower than the end surface of the lens barrel 62 in the axial direction X of the center hole 621.

In some realizable manners, referring to fig. 9, a second accommodating portion 60b is formed on the inner wall of the central hole 621 between a region of the inner connecting portion 622 on the side facing away from the light inlet portion of the lens 61 and the lens 61. When the first connecting glue 63 overflows, the second accommodating portion 60b can accommodate the overflowing first connecting glue 63, so that the overflowing first connecting glue 63 can be positioned between the lens 61 and the lens barrel 62, and cannot directly flow to the inner wall of the central hole 621 and be directly exposed to the inner wall of the lens barrel 62, and the possibility that the lens barrel 62 and other structural components are in an unnecessary bonding state due to the fact that the first connecting glue 63 directly exposed to the inner wall is bonded to other structural components adjacent to the lens barrel 62 in the camera module 60 is reduced.

In some examples, the first and

second receptacles

60a and 60b may each be annular.

In some realizable manners, along the axial direction X of the central hole 621, the surface of the second connection glue 64 facing the light intake portion is lower than the end surface of the lens barrel 62 facing the light intake portion, so that the second connection glue 64 is not easy to be adhered to other structural members outside the lens barrel 62.

In some examples, along the axial direction X of the central hole 621, when the surface of the second connection glue 64 facing the light inlet portion is lower than the end surface of the lens barrel 62 facing the light inlet portion with the height of the lens barrel 62 unchanged, the amount of the second connection glue 64 is relatively reduced. In the embodiment of providing the annular receiving groove 612 on the lens 61, the amount of the second connection glue 64 can be increased, which is beneficial to reducing the possibility that the amount of the second connection glue 64 is less because the second connection glue 64 is lower than the end surface of the lens barrel 62.

In some examples, referring to fig. 9, the central bore 621 includes a first bore segment 621a and a second bore segment 621b. The diameter of the first hole section 621a is smaller than that of the second hole section 621b. The first and

second hole sections

621a and 621b are located on a side of the inner connection portion 622 facing the light intake portion. The first and

second hole sections

621a and 621b may form a first receiving portion 60a with the lens 61. The second hole section 621b is disposed on a side of the first hole section 621a facing away from the inner connection portion 622. At least a portion of the second connection paste 64 is disposed between the first hole section 621a and the lens 61.

In some realizable ways, as shown in fig. 8 and 9, a portion of the lens 61 is disposed beyond an end face of the barrel 62. The lens 61 includes a housing 61a and a lens 61b. The housing 61a may have a cylindrical structure. The lens 61b is disposed within the housing 61a. The housing 61a may be used to hold the lens 61b and may protect the lens 61b. In some examples, the plurality of lenses 61b may be aligned along the axial direction X of the central hole 621. The housing 61a of the lens 61 is an integrally molded structure. The outer connection portion 611 of the lens 61 is provided to the housing 61a. A part of the housing 61a is disposed beyond the end surface of the lens barrel 62. The portion of the housing 61a provided with the outer connecting portion 611 is located within the center hole 621 of the lens barrel 62.

In some realizable manners, referring to fig. 9, the outer connection portion 611 and the inner connection portion 622 are both threaded sections, that is, both the outer connection portion 611 and the inner connection portion 622 are threaded, so that the connection structure of the outer connection portion 611 and the inner connection portion 622 can be simple, and the connection stability of the two can be ensured. The first connection glue 63 fills the thread gap between the outer connection part 611 and the inner connection part 622, so that on one hand, the connection area between the lens 61 and the lens barrel 62 and the first connection glue 63 can be increased, the connection strength is improved, and the lens 61 and the lens barrel 62 have higher impact resistance; on the other hand, the first connection paste 63 can fill the thread play between the outer connection part 611 and the inner connection part 622, so that the possibility that the lens 61 is easily rotated relative to the lens barrel 62 to be loosened due to the large thread play between the outer connection part 611 and the inner connection part 622 can be reduced.

In some examples, the outer connection portion 611 and the inner connection portion 622 are the same size along the axial direction X of the central hole 621. The first connection paste 63 is pressed by the outer connection parts 611 and the inner connection parts 622. The first connection paste 63 may completely cover the outer connection parts 611 and the inner connection parts 622.

In some examples, one circle of the first connection paste 63 is provided along the circumferential direction of the lens 61 in a region of the outer connection portion 611 away from the light entrance portion of the lens 61, or one circle of the first connection paste 63 is provided along the circumferential direction of the lens barrel 62 in a region of the inner connection portion 622 close to the light entrance portion of the lens 61. Then, as the outer connection part 611 is gradually screwed into the inner connection part 622, the outer connection part 611 and the inner connection part 622 may press the first connection paste 63 so that the first connection paste 63 may spread out, and thus the first connection paste 63 may cover the outer connection part 611 and the inner connection part 622.

In some implementations, the camera module 60 includes a Voice Coil Motor (VCM). The voice coil motor includes a housing. The lens barrel 62 is disposed within the housing. The voice coil motor can drive the lens 61 and the lens barrel 62 to move along the optical axis direction synchronously, so that focusing is realized to obtain a clear image. The optical axis direction may refer to a direction in which light enters the light entrance portion.

In some examples, the first connection glue 63 may include, but is not limited to, an acrylic glue and a modified system thereof, an epoxy glue and a modified system thereof, a polyurethane glue or a silicone glue system. The first connecting glue 63 is made of glue with high viscosity or high thixotropic index, so that in the process of connecting the outer connecting portion 611 and the inner connecting portion 622, the first connecting glue 63 is not easy to overflow due to too high fluidity, and the possibility of bonding the overflow glue with the lens 61 and other structural members except the lens barrel 62 is reduced. Illustratively, the camera module 60 may include a voice coil motor. The voice coil motor comprises a spring plate connected to the shell. The lens barrel 62 is connected with the elastic sheet. When the lens barrel 62 moves along the optical axis, the lens barrel 62 can drive the elastic sheet to actuate. Since the first connection glue 63 is not easy to flow, the first connection glue 63 is not easy to overflow to flow to the elastic sheet and adhere to the elastic sheet. The thixotropic index refers to a value represented by a ratio of viscosity measured at a low rotation speed and a high rotation speed under the same condition. The larger the thixotropic index is, the higher the thixotropy of the glue is, and conversely, the smaller the thixotropic index is, the lower the thixotropy of the glue is.

Illustratively, the viscosity of the first connection paste 63 is greater than 20000CPS. The value of the thixotropic index of the first connecting glue 63 is greater than 4.

In some implementations, after the outer connection portion 611 and the inner connection portion 622 are connected, the first connection glue 63 is located between the lens 61 and the lens barrel 62. The first connection paste 63 may be cured by baking or natural curing. The natural curing method may include, but is not limited to, moisture, anaerobic curing, solvent evaporation, and the like.

In some examples, the material of the first connection paste 63 and the material of the second connection paste 64 are the same. After the second connection paste 64 is set in the first receiving portion 60a, the first connection paste 63 and the second connection paste 64 are simultaneously subjected to curing treatment. Illustratively, the viscosity of the first connecting glue 63 is the same as the viscosity of the second connecting glue 64. The thixotropic index of the first connecting glue 63 has the same value as the thixotropic index of the second connecting glue 64.

In other examples, the material of the first connection paste 63 and the material of the second connection paste 64 are different. The second connection paste 64 may be UV paste. After the curing process of the first connection paste 63 is completed, the second connection paste 64 is set in the first receiving portion 60a. Then, the second connection paste 64 is irradiated with UV light to cure the second connection paste 64. Since the first connection paste 63 is cured in advance and then the second connection paste 64 is set and cured, the second connection paste 64 is not easily interfered with the first connection paste 63.
