The inner wall of the shell facing the lens is provided with a dust removing structure, so that the area of the shell facing the movement path of the lens forms an uneven surface. When the camera shooting assembly stretches, the protruding part of the uneven surface scrapes off dust attached to the lens.

Wherein, the motion path of the lens refers to: the camera shooting component moves from the inside of the shell to the path of the lens when the camera shooting component completely extends out of the shell. In addition, the mobile terminal mentioned in the present application includes, but is not limited to, electronic devices such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a camera, a navigation device, a wearable device, a smart band, a pedometer, and the like.

For further explanation of the principles and construction of the present application, preferred embodiments thereof will now be described in detail with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, in an embodiment of the present application, a housing 11 of a mobile terminal 1 includes a front shell 111 and a rear shell 112, and a receiving cavity 113 is disposed inside the housing 11, where the receiving cavity 113 may be used to receive a camera assembly 12. The through hole 110 at the top of the housing 11 is communicated with the accommodating cavity 113, and the camera assembly 12 can extend out of or retract into the accommodating cavity 113 of the housing 11 through the through hole 110. It is understood that in the above-described embodiment, the through hole 110 may also be opened at the side and bottom of the housing 11.

The camera assembly 12 of the present embodiment further includes a fixing frame 123, and the fixing frame 123 is used for mounting the camera 121. The fixing frame 123 is provided with a mounting hole at a position corresponding to the front surface of the camera 121, and the lens 122 is mounted in the mounting hole to face the camera 121. Foam is filled between the fixing frame 123 and the camera 121 to seal and prevent dust in the internal space of the camera assembly 12.

In this embodiment, the camera 121 is a front camera, and a front surface of the front camera is opposite to the front shell 111 when the camera assembly 12 retracts into the accommodating cavity 113. In addition, the camera 121 may also be a rear camera, and a front surface of the rear camera is opposite to the rear case 112.

Further, the inner wall of the front case 111 of the present embodiment is recessed with a dust containing groove 13 to form a dust removing structure of the mobile terminal 1. The dust holding groove 13 is arranged corresponding to the moving path of the lens 122, and the dust holding groove 13 is formed by the inner wall of the front shell 111 sinking towards the direction far away from the camera assembly 12, so that the area of the shell 11 facing the moving path of the lens 122 forms an uneven surface. Wherein, the notch of the dust containing groove 13 is a protruding part relative to the groove bottom of the dust containing groove 13.

When the camera module 12 is extended or retracted from the through hole 110, the notch of the dust holding groove 13 contacts with larger dust particles on the lens 122, and the diameter of the larger dust particles is about 100 μm. The groove opening of the dust containing groove 13 is in direct contact with dust particles, and the dust particles with large diameters can be adhered to the groove opening of the dust containing groove 13 due to the strong adhesive force of the dust particles, so that the dust particles are scraped by the groove opening of the dust containing groove 13 to be separated from the surface of the lens 122, and finally the scraped dust particles are left in the dust containing groove 13. After the notch of the dust holding groove 13 contacts with the dust particles on the lens 122, the dust on the lens 122 will be scraped off by the notch of the dust holding groove 13, so as to ensure that the camera assembly 12 has no dust attached to the lens 122 when extending out of the housing 11. When the user uses the camera module 12, the user does not need to wipe the lens 122 with hands or a mirror wiping cloth, and the camera 121 finally images without black spots, so that the good shooting and imaging effect of the mobile terminal 1 can be ensured. In addition, the scraped dust can be retained in the dust containing groove 13, so as to avoid scattering and accumulating in other areas inside the housing 11, and ensure the normal use of the mobile terminal 1.

As shown in fig. 3, in the above embodiment, the area of the front shell 111 facing the moving path of the fixed frame 123 may be further provided with the inclined surface 114, and the inclined surface 114 is configured to avoid the fixed frame 123 when the camera module 12 extends and contracts, so as to prevent the fixed frame 123 from contacting with the inner wall of the front shell 111 when the camera module extends and contracts.

With the mobile terminal 1 of the present embodiment, when the camera assembly 12 extends and contracts through the through hole 110, the camera assembly 12 may slightly shake, which may cause the camera assembly 12 to incline to some extent. Lens 122 of the subassembly 12 of making a video recording of slope can contact with the notch of dust holding groove 13, and the inclined plane 114 on preceding shell 111 inner wall can dodge fixed frame 123 this moment, avoids fixed frame 123 butt on preceding shell 111 inner wall, guarantees that subassembly 12 of making a video recording can be stretched out smoothly by through-hole 110.

When the notch of the dust containing groove 13 contacts with the lens 122 of the camera shooting assembly 12, as the camera shooting assembly 12 extends out of the shell 11, the notch of the dust containing groove 13 and the surface of the lens 122 form line-surface contact, so that dust attached to the lens 122 is scraped off, and the dust is left in the dust containing groove 13.

Further, in the present embodiment, referring to fig. 4, the cross section of the dust containing groove 13 is rectangular, the notch edge line of the dust containing groove 13 includes a first edge 131 and a second edge 132 which are arranged in parallel, and the extending direction of the first edge 131 and the second edge 132 is perpendicular to the direction of the telescopic path of the camera module 12. Wherein the first edge 131 is disposed near the through hole 110, and the second edge 132 is disposed far from the through hole 110.

As shown in fig. 5, when the camera module 12 is located in the accommodating cavity 113, the first edge 131 of the present embodiment is higher than the top of the camera module 12, the second edge 132 is lower than the bottom of the camera module 12, and a part of the area of the dust accommodating groove 13 is located corresponding to the moving path of the lens 122.

In the present embodiment, the width of the projection of the lens 122 on the inner wall of the housing 11 falls within the dust holding groove 13, so that the dust holding groove 13 completely covers the lens 122 of the camera assembly 12, and it is ensured that the dust on the surface of the lens 122 is completely scraped by the notch of the dust holding groove 13.

When the camera module 12 extends out of the accommodating cavity 113, the camera module 12 slightly shakes in the accommodating cavity 113, and the surface of the lens 122 gradually contacts with the first edge 131 of the dust accommodating groove 13 in the ascending process, so that the first edge 131 scrapes off dust on the lens 122, thereby ensuring that no dust adheres to the lens 122 extending out of the housing 11. The dust scraped off by the first edge 131 falls to and remains in the dust containing groove 13, and the dust is prevented from adhering to other functional components of the mobile terminal 1.

As shown in fig. 6, in the present embodiment, when the camera module 12 is located in the accommodating cavity 113, the dust holding groove 13 may also be arranged such that the first edge 131 is higher than the top of the camera module 12, the second edge 132 is higher than the bottom of the camera module 12 but lower than the top of the camera module 12, and the dust holding groove 13 is arranged corresponding to the moving path of the lens 122.

When the camera module 12 protrudes from the accommodating cavity 113, along with the movement of the camera module 12, the surface of the portion of the lens 122 above the second edge 132 contacts the first edge 131, and the surface of the portion of the lens 122 below the second edge 132 contacts the second edge 132 and the first edge 131 of the dust accommodating groove 13, respectively, so that dust attached to the lens 122 is scraped.

As shown in fig. 7, in the above embodiment, when the camera module 12 is located in the accommodating cavity 113, the second edge 132 of the dust holding groove 13 may also be higher than the top of the camera module 12, and the dust holding groove 13 is arranged corresponding to the moving path of the lens 122. When the camera module 12 protrudes from the accommodating cavity 113, the surface of the lens 122 sequentially contacts with the first edge 131 and the second edge 132 of the dust containing groove 13 along with the movement of the camera module 12, so that the dust on the surface of the lens 122 is scraped.

It should be noted that the cross section of the dust holding groove 13 is not limited to a rectangle, but may also be a circle, an ellipse, or another polygon, as long as the side line of the notch of the dust holding groove 13 close to the through hole 110 is higher than the top of the lens 122, so as to ensure that the lens 122 contacts with the notch of the dust holding groove 13 in the process of extending and retracting the camera assembly 12.

Further, in the present embodiment, the dust containing groove 13 has a groove depth of 0.1mm to 0.2 mm. The arrangement ensures that the dust containing groove 13 contains dust on the surface of the lens 122, and meanwhile, the arrangement of the dust containing groove 13 can be prevented from influencing the structural strength of the shell 11, and the overall stability of the shell 11 is ensured.

In addition, the interval is arranged between the camera shooting assembly 12 and the inner wall of the shell 11, so that the camera shooting assembly is prevented from being stuck in the telescopic process, and the camera shooting assembly 12 can be freely stretched.

In the present embodiment, the ratio of the distance between the camera module 12 and the inner wall of the housing 11 to the depth of the dust containing groove 13 is 1:1-1: 2. The arrangement can ensure that the camera assembly 12 can be used normally, can smoothly extend out of the through hole 110 when shooting images, and can ensure that dust on the lens 122 can be accommodated in the dust accommodating groove 13, thereby preventing the dust from scattering at other parts inside the shell 11 and ensuring the reliability of other functional components in the shell 11.

Further, referring to fig. 4, a flexible body 15 is disposed at the notch of the dust containing slot 13 of the present embodiment, and the flexible body 15 and the dust containing slot 13 together form a dust removing structure of the mobile terminal 1. The flexible body 15 is used for contacting with the lens 122 when the camera shooting assembly 12 stretches, the hardness of the flexible body 15 is small, the flexible body 15 replaces a notch of the dust containing groove 13 to be in contact with the surface of the lens 122, abrasion of the surface of the lens 122 can be avoided, and therefore the lens 122 of the camera shooting assembly 12 is protected in the dust removing process.

In this embodiment, since the surface of the lens 122 contacts only the first side 131 when the camera module 12 is extended or retracted, the flexible body 15 may be provided only on the first side 131. In addition, flexible bodies may be provided on both the first side 131 and the second side 132, or the flexible bodies 15 may be arranged on the side lines of the notch of the dust containing groove 13, so that the flexible bodies 15 contact the surface of the lens 122 when the camera module 12 extends and contracts.

The flexible body of the present embodiment is made of silicone or rubber, and some materials with lower hardness and softer texture. In this embodiment, the flexible body is in the form of a strip, which is adhesively fixed at the slot of the dust holding slot 13.

A flexible body 15 is provided at the notch of the dust containing groove 13, and when the camera module 12 is extended and contracted, the surface of the lens 122 is directly contacted with the flexible body 15. The hardness of the flexible body 15 is far less than that of the lens 122, when the two contact each other, the flexible body 15 can scrape off dust on the surface of the lens 122, but the lens 122 cannot be worn, so that the camera shooting assembly 12 is prevented from being damaged, the camera shooting assembly 12 is protected in the dust removal process, and the service life of the camera 121 is prolonged.

The cross section of the flexible body 15 of the present embodiment can be circular, semicircular or elliptical, and the arc-shaped surface of the flexible body 15 is opposite to the lens 122. When the camera assembly 12 stretches, the flexible body 15 and the surface of the lens 122 form tangential contact, so that the abrasion of the surface of the lens 122 caused by surface-to-surface contact is avoided, and the damage to the camera assembly 12 in the dust removal process is further prevented. In addition, the cross-section of the flexible body 15 may be other shapes, such as triangle, rectangle, irregular polygon, etc., without limitation.

Referring to fig. 8, in the present embodiment, one end of the dust containing groove 13 may penetrate through the through hole 110 of the housing 11, so that the inside of the dust containing groove 13 is communicated with the outside of the housing 11 through the through hole 110.

In the present embodiment, the end of the dust containing slot 13 far away from the through hole 110 is a dust removing end 133, and the side line of the dust removing end 133 close to the notch of the dust containing slot 13 is a dust removing edge 134. When the camera module 12 is located in the accommodating cavity 113, the dust removing edge 134 is closer to the through hole 110 of the housing 11 than the end of the camera module 12, and the dust removing end 133 is disposed corresponding to the moving path of the lens 122.

When the camera module 12 protrudes from the accommodating cavity 113, the camera module 12 slightly shakes in the accommodating cavity 113 to bring the gradually protruding lens 122 into contact with the dust removing edge 134. During the extension of the camera module 12, the dust removing edge 134 gradually scrapes off the dust attached to the lens 122 and leaves the dust in the dust containing groove 13.

With the mobile terminal 1 of the present embodiment, since the inside of the dust containing groove 13 is communicated with the outside of the housing 11 through the through hole 110, the user can clear away the dust accumulated inside the dust containing groove 13 through the through hole 110 of the housing 11, so as to prevent the dust from being accumulated inside the dust containing groove 13 for a long time and prevent the dust inside the dust containing groove 13 from adhering to the lens 122 of the camera assembly 12.

In addition, a flexible body 15 may be provided on the dust collecting edge 134 of the dust collecting tank 13, and the flexible body 15 and the dust collecting tank 13 together constitute a dust collecting structure. As camera assembly 12 telescopes, the surface of lens 122 directly contacts flexible body 15. The hardness of the flexible body 15 is far less than that of the lens 122, when the two contact each other, the flexible body 15 can scrape off dust on the surface of the lens 122, but the lens 122 cannot be worn, so that the camera shooting assembly 12 is prevented from being damaged, the camera shooting assembly 12 is protected in the dust removal process, and the service life of the camera 121 is prolonged.

In the above embodiment, as shown in fig. 9, the dust holding groove 13 may be eliminated from the housing 11, and the dust removing member 14 may be disposed on the inner wall of the housing 11 facing the lens 122. The surface of the dust removing member 14 protrudes from the inner wall of the housing 11 to constitute a dust removing structure of the mobile terminal 1.

Wherein the surface of the dust removing member 14 is a more protruded portion than the inner wall of the front case 111. The dust removing member 14 is used to contact the lens 122 to remove dust attached to the lens 122.

In this embodiment, the dust removing member 14 is a brush or a cotton cloth. In the process of extending and retracting the camera module 12, the brush or the cotton cloth can contact with the surface of the lens 122, so as to wipe off dust attached to the surface of the lens 122, and ensure the cleanness of the surface of the lens 122 when the camera module 12 is completely extended out of the housing 11.

Further, when the camera module 12 is completely located in the housing 11, the dust removing member 14 is closer to the through hole 110 of the housing 11 than to the end of the camera module 12, and the dust removing member 14 extends in the width direction of the lens 122.

In addition, both ends of the dust removing member 14 extend outward beyond the projection of the lens 122 on the inner wall of the housing 11. When the camera module 12 is extended and retracted through the through hole 110, the dust removing part 14 can be in complete contact with the surface of the lens 122 in the width direction thereof, so that dust on the lens 122 can be completely removed by the dust removing part 14.

In this embodiment, the dust removing member 14 is telescopically disposed on the inner wall of the housing 11 to be close to or far from the lens 122 of the camera assembly 12.
