[0028] In combination Figures 1 to 6 The application provides an external camera module 10, which comprises a module shell 11, a camera 12 and a sealing structure 13. The module shell 11 is internally provided with a front receiving part 113, the camera 12 is installed in the front receiving part 113, and the sealing structure 13 is installed on the camera 12 and is pressed between the inner wall of the front receiving part 113 and the camera 12. Since the camera 12 is arranged in the front receiving part 113, the sealing structure 13 can be located between the camera 12 and the inner wall of the front receiving part 113. At this time, a certain cavity is formed between the sealing structure 13 and the inner wall of the front receiving part 113, which can accommodate the lens part of the camera 12, so as to avoid the lens part of the camera 12 from contacting the outside, thereby avoiding dust, water vapor or other impurities from entering the inside of the camera 12 to pollute the lens part of the camera 12. Since dust, water vapor and other impurities can be isolated, the camera 12 can also be prevented from being polluted to affect the imaging quality and service life.

[0029] In an embodiment, in combination Figures 4 to 6 The front receiving part 113 is internally provided with a limiting groove 1131, the bottom of the limiting groove 1131 is provided with a through hole 1132, the limiting groove 1131 is used for accommodating the camera 12, part of the camera 12 can extend out of the through hole 1132, and the sealing structure 13 is located between the camera 12 and the inner bottom 1131a of the limiting groove 1131. Part of the camera 12, i.e., the lens part, can extend out of the through hole 1132 at the bottom of the limiting groove 1131. At this time, the limiting groove 1131 can reduce the pollution of the lens part of the camera 12 by external impurities to a certain extent. When the sealing structure 13 is sealed between the camera 12 and the inner bottom 1131a of the limiting groove 1131, the sealing structure 13 is sealed around the camera 12 and the through hole 1132, so as to further avoid external impurities from entering the space where the lens part of the camera 12 is located through the through hole 1132. Therefore, the sealing structure 13 cooperates with the limiting groove 1131 to further improve the isolation effect of dust, water vapor and other impurities.

[0030] In an embodiment, in combination Figures 2 to 6The external camera module 10 further comprises a front cover plate 15, the front cover plate 15 is made of transparent material, the front cover plate 15 is arranged on the module shell 11 and located outside the limiting groove 1131, so that the part of the camera 12 extending out of the through hole 1132 faces the front cover plate 15. The part of the camera 12 extending out of the through hole 1132 is the lens part of the camera 12. As known from the above, the front cover plate 15 and the limiting groove 1131 are located on both sides of the bottom of the limiting groove 1131. At this time, the lens part of the camera 12 is contained between the front cover plate 15 and the outside of the limiting groove 1131. Since the front cover plate 15 blocks dust and water vapor from polluting the camera 12 from the lens part of the camera 12, the sealing structure 13 blocks dust and water vapor from polluting the camera 12 from the back of the lens part of the camera 12 by sealing the through hole 1132. Under the dual action of the front cover plate 15 and the sealing structure 13, the external dust, water vapor and other impurities cannot enter the space where the lens part of the camera 12 is located through the through hole 1132 and the front cover plate 15. Therefore, the imaging effect of the camera 12 can be ensured, thereby prolonging the service life of the camera 12.

[0031] In an embodiment, the front cover plate 15 is connected with the module shell 11 through the double-sided adhesive tape 16. The double-sided adhesive tape 16 can improve the connection tightness of the front cover plate 15 and the module shell 11, thereby ensuring that the front cover plate 15 is stably fixed on the module shell 11.

[0032] In an embodiment, the material of the sealing structure 13 is foam or double-sided adhesive tape. The high elasticity and compression resilience of the foam can better realize the sealing effect of the camera 12, thereby effectively blocking dust, water vapor and other impurities, and further improving the dustproof and moistureproof effect of the lens.

[0033] In an embodiment, continuing to refer to Figure 2 The width d2 of the double-sided adhesive tape 16 is not less than 0.8 mm. The width d2 of the double-sided adhesive tape 16 not less than 0.8 mm can improve the connection firmness of the double-sided adhesive tape 16 connecting the front cover plate 15 and the module shell 11, and also achieve better sealing.

[0034] In an embodiment, continuing to refer to Figure 2 The thickness d1 of the sealing structure 13 is between 0.45 mm and 0.55 mm. At this time, the elasticity of the sealing structure 13 can be ensured, and the sealing effect can also be ensured.

[0035] Referring to Figure 2 and Figure 5The external camera module 10 further comprises a support 14 arranged in the front receiving portion 113. Since there are more than one ways to fix the camera 12, the external camera module 10 of the present application is provided with two cameras 12, which are respectively named as a first front camera 121 and a second front camera 122. The first front camera 121 and the second front camera 122 are installed on the support 14 in different ways. For the convenience of distinction, the sealing structure 13 corresponding to the first front camera 121 is a first sealing structure 131, and the sealing structure 13 corresponding to the second front camera 122 is a second sealing structure 132. For example, the position of the B-B cross section is the position of the first front camera 121, and the position of the A-A cross section is the position of the second front camera 122. Figure 1

[0036] In an embodiment, referring to Figure 4 Figure 5 The sealing structure 13 is arranged in a ring shape, and the ring-shaped sealing structure 13 is sleeved on the camera 12. The ring-shaped sealing structure 13 can provide 360-degree protection and sealing for the part of the camera 12 sleeved thereon. At this time, the sealing structure 13 can also provide 360-degree protection and sealing for the through hole 1132, thereby avoiding the pollution of the lens part of the camera 12 by external impurities through the through hole 1132. Therefore, the ring-shaped sealing structure 13 can further improve the sealing effect.

[0037] In an embodiment, referring to Figures 4 to 6 The support 14 is provided with a mounting hole 141. Taking the case that the second front camera 122 is arranged on the support 14 through the mounting hole 141 as an example, at this time, the second front camera 122 is installed on the support 14 and can pass through the mounting hole 141. The support 14 is located between the camera 12 and the inner bottom 1131a of the limiting groove 1131, and the second sealing structure 132 is pressed between the inner bottom 1131a of the limiting groove 1131 and the support 14. The support 14 can support the second front camera 122 and prevent the second front camera 122 from shaking, thereby ensuring the stability of the second front camera 122 fixed in the external camera module 10. In addition, since the second front camera 122 passes through the mounting hole 141 first, the support 14 can block some dust and other impurities from affecting the imaging of the second front camera 122, and the arrangement of the support 14 further improves the isolation effect of dust, water vapor and other impurities.

[0038] In an embodiment, referring to Figures 4 to 6 ​​The bracket 14 is provided with a mounting groove 142. Taking the first front camera 121 mounted on the bracket 14 through the mounting groove 142 as an example, the first front camera 121 is mounted on the mounting groove 142, the first front camera 121 is located between the mounting groove 142 and the inner bottom 1131a of the limiting groove 1131, and the first sealing structure 131 is located between the inner bottom 1131a of the limiting groove 1131 and the bracket 14. Due to the common limiting of the mounting groove 142 and the limiting groove 1131, the first front camera 121 can be stably fixed in the external camera module 10. Since the sealing structure 13 is also arranged on the first front camera 121, the first sealing structure 131 can be pressed between the inner bottom 1131a of the limiting groove 1131 and the mounting groove 142. At this time, the first sealing structure 131 can also seal the through hole 1132 of the limiting groove 1131, thereby avoiding external impurities from entering the lens part of the first front camera 121 through the through hole 1132 and affecting the imaging effect.

[0039] In an embodiment, in combination with Figures 3 to 6 The sealing structure 13 is provided with an annular protrusion 133 on the side facing the inner bottom 1131a of the limiting groove 1131. Taking the first sealing structure 131 provided with the annular protrusion 133 as an example, the annular protrusion 133 abuts against the inner bottom 1131a of the second limiting groove 1131. The arrangement of the annular protrusion 133 further enhances the sealing effect of the first sealing structure 131, and further avoids the possibility that external impurities enter the space where the lens part of the first front camera 121 is located through the through hole 1132 and affect the imaging effect.

[0040] In an embodiment, the outer surface 11a of the module shell 11 is a frosted surface. It can not only enhance the hand feeling, but also realize the anti-skid performance.
