The present disclosure will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present disclosure and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second", and the like in the specification and claims of the present disclosure are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

Before introducing the embodiments of the present disclosure, a scheme for shielding a camera using a shield cover in the related art will first be described.

The shielding cover is disposed on the periphery of the camera module, which can protect the camera from external static electricity or other signals, ensure the normal operation of the camera, and improve the picture quality of the camera; in addition, the shielding cover can effectively reduce the camera mode. The group interferes with peripheral devices, such as reducing the interference of the camera module to the antenna.

The shielding cover in the related art may be a metal shielding cover for shielding signals, and the metal shielding cover is disposed at the periphery of the camera module to shield the camera module. Moreover, the shielding cover is disposed on the surface of the camera with a light-passing hole, wherein the light can enter the shielding cover through the light-passing hole to facilitate the camera to take a picture. The shielding cover is adhered to the camera module, and a plurality of pins are left on the shielding cover. The shielding cover can be inserted into a plurality of jacks on the main board, and the shielding cover is fixed on the main board by welding to pass through the shielding cover. The upper pin is mated with the jack of the motherboard to ground the shield.

In the above camera shielding scheme in the related art, there is a problem that the above solution requires adding a metal shield on the periphery of the camera module, and the metal shield increases the thickness of the terminal, and the camera shielding scheme forms a thinner and thinner terminal. Larger impact. In addition, the shield cover attached to the outside of the camera module may also affect the angle of view of the camera. Currently, the design of the camera module generally uses a camera with a large optical angle of view, although in the above scheme, the surface of the shield There is a light-passing hole, but the camera is still in the shielding cover, or only part of the light-emitting hole is exposed outside the shielding cover. For the module with large light source, it is very possible to block the optical field of view of the camera. Form a vignetting angle and affect the picture quality. In addition, the shielding cover is bonded to the camera module through the bottom, and the bottom pin is connected with the main board by welding. In the process of dropping, because the shielding cover itself is heavier, the shielding cover is likely to fall off; or because the shielding cover is cited Loose soldering between the foot and the motherboard can also cause the shield to fall off.

In the embodiment of the present disclosure, a terminal is provided, including a camera module, wherein the camera module includes a camera and a motor, wherein the motor is grounded.

In general, the camera module in the terminal can include a camera, a sensor, a circuit board, and a motor, wherein the motor in the camera module can be used to achieve focusing of the camera. Grounding the motor of the camera module, so that the motor of the camera module functions as a shield of the camera module, so that there is no need to additionally provide a shield for the camera module, and since the motor itself is a part of the camera module, There is no problem of interference with the camera effect of the camera module, and it is easy to fall off, thereby effectively solving the problem that the shield cover existing in the related art affects the camera effect of the camera module and the shield cover is easy to fall off.

In an optional embodiment, the motor of the camera module can be grounded through a ground connection with the outer casing of the terminal. That is, the motor of the camera module is grounded through the outer casing of the terminal. The following describes how to ground the housing through the terminal:

In an optional embodiment, the fixing module for fixing the camera in the outer casing is provided with a metal piece, wherein the first end of the metal piece is used for contacting the ground of the outer casing, and the second end is for contacting with the motor. . That is, in the present embodiment, a metal piece is newly added to the fixed module of the camera as compared with the related art terminal. Moreover, both ends of the metal piece may be in contact with the motor and the outer casing, respectively. Since the metal piece can be electrically conductive, the motor can be indirectly connected to the ground of the outer casing.

The metal sheet may be arranged in a plurality of manners in the fixing module. In an optional embodiment, the first end of the metal piece may be disposed in the interior of the fixed module, and the second end is located at a position corresponding to the motor. Exposed to the fixed module, wherein the first end of the metal piece is used for connecting to the ground of the outer casing, and the second end of the metal piece is used for contacting the motor. By adopting the above-mentioned metal sheet setting method, the stability of the metal sheet can be ensured, and it is not easy to fall, and the connection between the motor and the terminal housing is ensured.

In an alternative embodiment, the exposed sheet metal portion at the location corresponding to the motor is a metal dome. In this embodiment, the metal shrapnel is used to avoid a gap between the metal piece and the motor, so that the metal piece and the motor are in close contact, so that when the terminal is shaken and dropped, a gap is formed between the metal piece and the motor, and the motor is caused. Poor contact with the outer casing and loss of shielding.

In an alternative embodiment, the metal sheet is a copper sheet. Since the copper sheet is low in cost and excellent in electrical conductivity, a copper sheet can be used as the above-mentioned metal sheet. In practical applications, metal sheets of other materials, such as iron sheets and aluminum sheets, may also be used.

In an optional embodiment, the fixing module is a fixed module made of plastic material.

In an optional embodiment, the camera is a rear camera; and/or the housing is a terminal front housing. Optionally, the camera may also be a front camera, and/or the outer casing may also be a terminal back shell.

In the embodiment, a method for shielding a camera is proposed, which is different from the solution generally adopted in the related art by adding a shield to the periphery of the camera module. In the embodiment of the present disclosure, a terminal having a special structure is designed. The front shell and the metal shell of the motor of the camera module are grounded, so that the motor of the camera module itself functions as a shield cover, and the external spoke of the camera module can be effectively shielded Shooting and interference from the outside. In addition, the problem that the shielding cover on the periphery of the camera module in the related art affects the imaging effect of the camera module and is easy to fall off is also solved.

The solution adopted in this embodiment can ground the motor metal casing of the camera without changing the appearance of the current camera module, thereby achieving the effect of shielding the electromagnetic radiation of the camera.

Hereinafter, the present invention will be described by taking the above camera as a rear camera in the terminal, and the above casing is a front case in the terminal as an example:

1 is a structural view of a front housing of a terminal in the related art, and FIG. 2 is a structural front view of a front housing according to an embodiment of the present disclosure. By comparing FIG. 1 and FIG. 2, the front housing of the terminal is used for protection and fixing. The plastic wall around the rear camera (the number of walls including but not limited to four) has been redesigned with copper sheets (other similar conductive materials can also be used) in the middle of the plastic wall. The earth is connected, and at the same time, a slit of a horizontal strip is left at a certain height of the wall surface, so that the copper piece in the plastic wall surface can be exposed. The portion of the copper that is exposed at the gap is designed as a shrapnel that allows it to be in full contact with the motor casing. The design in the embodiment of the present disclosure avoids providing a special shielding cover on the periphery of the camera module, and the same shielding effect as the external shielding cover is achieved by grounding the motor of the camera module itself. Since there is no external shielding cover, the solution does not cause a certain occlusion of the angle of view of the camera itself, and there is no potential risk of falling off the shield or poor contact for the drop. At the same time, this solution does not increase the height dimension of the module, and does not cause obstacles to the thinning of the terminal.

The terminal front shell structure in the embodiment of the present invention is described in detail below with reference to FIG. 2:

In the embodiment of the present disclosure, a terminal front case having a new structure is designed, that is, a metal piece is disposed in a plastic wall surface of the front case of the terminal. The metal piece can ground the motor of the rear camera module of the terminal, so that the metal casing of the motor shields the external radiation signal of the camera module, and functions like a shield cover, which can effectively reduce the camera module to the terminal. The interference of peripheral devices such as antennas enhances the sensitivity of the network signal when the antenna is working, so that the user can use less signals or even less when the external network signal is weak. The phenomenon that the Internet is not connected; at the same time, the grounded motor metal casing can shield the interference from the external signal to the camera, and the image quality of the rear camera imaging will also be improved.

In addition, considering that the rear camera is generally close to the antenna of the terminal, and if there is a metal device near the antenna (such as the copper piece disposed on the plastic wall of the front case of the terminal), the metal device will form an antenna signal. Reflection, it is possible to reduce the strength of the signal received by the antenna. Therefore, if the copper piece on the plastic wall surface is directly exposed outside the plastic wall in this case, it will affect the normal operation of the antenna. Moreover, the copper sheet is directly attached to the surface of the plastic wall, which is more likely to cause problems such as the copper sheet falling off due to poor adhesion.

The terminal front case with the new structure provided by the embodiment of the present invention embeds a metal piece (such as a copper piece) in the middle of the plastic wall surface to ensure that the copper piece is connected to the front cover of the earth, which is directly attached to the outer surface of the plastic wall. It can eliminate the reflection that may be formed on the antenna signal, and also prevent the copper sheet from falling off. In the design, a slit of a horizontal strip is formed on the plastic wall surface at the height of the motor of the camera, and the copper piece disposed in the middle of the plastic wall surface is exposed outside the plastic wall surface, and the copper piece is electrically connected to the motor casing here. In order to make the copper piece and the motor fully grounded, the exposed part of the copper piece at the gap is designed as a spring piece, which ensures that the copper piece can be in close contact with the motor, and does not form a gap between the copper piece and the motor in the case of shaking and falling, so that the motor casing Without grounding, the effect of shielding is lost.

In this embodiment, a mask interference method for operating the terminal is provided. FIG. 3 is a flowchart of a method for masking interference according to an embodiment of the present disclosure. As shown in FIG. 3, the process includes the following steps:

Step S302: grounding the motor of the camera in the terminal.
