In this embodiment, the top edge The positions of 421 and bottom edge 423 are exchanged, and the structural relationship is still established.

As for the above mobile terminal 10, since the rear surface 420 includes a flat area 401 covering the camera module 300, ambient light can pass through the flat area 401 and enter the camera module 300, and the battery cover 400 does not need to have a light-through hole, which is beneficial to maintain The appearance integrity of the battery cover 400 improves the appearance characteristics of the mobile terminal 10. Since the plane area 401 extends to the top edge 421, the optical axis of the camera module 300 can be arranged as close to the top edge 421 as possible, so that the internal components of the mobile terminal 10 are arranged more compactly. For example, in the mobile terminal 10 with this structure, the layout of the main board, battery and other components can be more flexible. For another example, since the camera module 300 is relatively close to the top edge 421, in some embodiments, by changing the position of some electronic components on the motherboard, the installation space of the battery can be increased to increase the size of the battery, thereby increasing the battery life of the mobile terminal 10. ability.

Specifically, in the embodiment shown in FIG. 6, the boundary line a formed by the intersection of the field of view and the back surface 420 is a circle, and the top edge 421 is a line segment, so the minimum distance between the boundary line a and the top edge 421 can be defined as follows : Move the line where the top edge 421 is located so that the line is tangent to the circle, and the minimum movement distance that can meet the tangent condition is the minimum distance between the boundary line a and the top edge 421. In other embodiments, the top edge 421 is an arc, and the minimum distance between the boundary line a and the top edge 421 can be defined as follows: any point on the top edge 421 is taken as a tangent, and the tangent is moved so that the tangent is tangent to the circle, Then the minimum moving distance of the tangent is the minimum distance between the boundary line a and the top edge 421. Since the circumferential edge of the battery cover 400 needs to be installed on the housing 200 by dispensing glue or the like, when the minimum distance between the boundary line a and the top edge 421 is in the above range, the optical axis of the camera module 300 can be made as close as possible The top edge 421 of the battery cover 400 can maintain a proper distance between the camera module 300 and the top edge 421, preventing the edge of the battery cover 400 from interfering with the field of view.

Referring to FIG. 7, in another embodiment, the mobile terminal 10 includes a display screen module 100, a housing 200, a camera module 300 and a battery cover 400.

The display module 100 can adopt an LCD (Liquid Crystal Display) screen or an OLED (Organic Light-Emitting Diode) screen. The housing 200 is roughly rectangular. The housing 200 may sometimes be referred to as a middle frame. It includes a metal base and a variety of accessory structures such as bosses, through holes, countersinks, and troughs that are injection molded on the metal base. The structure can be used for positioning the internal electronic components of the mobile terminal 10 to facilitate the assembly of electronic components such as the display module 100, the motherboard, and the battery of the mobile terminal 10 to the housing 200 and form a reliable connection with the housing 200. Among them, the material of the metal substrate may be aluminum alloy, magnesium alloy, or stainless steel.

Since the plane area 401 is connected to the top edge 421 by the transition surface 409, and the width d2 of the orthographic projection of the transition surface 409 on the reference plane is less than 0.2mm, the optical axis of the camera module 300 can be set as close to the top edge 421 as possible to make the mobile terminal The layout of 10 internal components is more compact. For example, in the mobile terminal 10 with this structure, the layout of the main board, battery and other components can be more flexible. For another example, since the camera module 300 is relatively close to the top edge 421, in some embodiments, by changing the position of some electronic components on the motherboard, the installation space of the battery can be increased to increase the size of the battery, thereby increasing the battery life of the mobile terminal 10. ability.

Since the circumferential edge of the battery cover 400 needs to be installed on the housing 200 by dispensing glue or the like, when the minimum distance between the boundary line a and the top edge 421 is in the above range, the optical axis of the camera module 300 can be made as close as possible The top edge 421 of the battery cover 400 can maintain a proper distance between the camera module 300 and the top edge 421, preventing the edge of the battery cover 400 from interfering with the field of view.
