The mobile terminal 10 can avoid the front camera occupying the area of the side where the display screen 130 is located, which is beneficial to improving the screen occupation ratio of the mobile terminal 10. For example, the screen ratio of the mobile terminal 10 adopting the above-described structure may be 85% or more.

The first wireless Communication module and the second wireless Communication module may implement near field Communication, and both employ the same Communication protocol, for example, the first wireless Communication module and the second wireless Communication module may be Bluetooth (Bluetooth) Communication modules, wiFi (Wireless Fidelity) Communication modules, zigBee Communication modules, or NFC (NEAR FIELD Communication) Communication modules. When the image capturing device 200 is detached from the host 100, the image capturing device 200 and the host 100 can be connected by the first wireless communication module and the second wireless communication module, so that a user can hold the image capturing device 200 to capture multiple angles and multiple scenes, and the captured data is transmitted to the host 100. For example, a user may hold the image capturing apparatus 200 with one hand and the host end 100 with the other hand, capture images of various positions and angles through the image capturing apparatus 200, and view the images through the display screen 130 of the host end 100. As another example, a user may place the image capture device 200 somewhere and view the image captured by the image capture device 200 through the host end 100 at another location.

Referring to fig. 8, the main board 250 is sleeved on the lens barrel 213 through the first opening 251. With the above structure, the lens barrel 213 of the camera module 210 can be prevented from being stacked on the main board 250, thereby being beneficial to the thinning of the overall thickness of the image capturing apparatus 200. Referring to fig. 9, in other embodiments, the main board 250 may be provided with a first through hole 252 so that the main board 250 is substantially annular, and the lens barrel 213 is disposed in the first through hole 252, which is also beneficial to the overall thickness reduction of the image capturing device 200. Referring to fig. 10, the main plate 250 may also have an "L" shape and define a first right angle region formed by two substantially perpendicular portions of the main plate 250, and the lens barrel 213 is disposed through the first right angle region. By providing the first right-angle area on the main board 250 and disposing the lens barrel 213 in the first right-angle area, the lens barrel 213 of the camera module 210 can be prevented from being stacked on the main board 250, thereby facilitating the thinning of the overall thickness of the image capturing apparatus 200.

Further, referring to fig. 7, the main board 250 may include a circuit board 254 and a second connection end 257, the second connection end 257 may be electrically connected to the circuit board 254, the first wireless communication module is connected to the circuit board 254, the circuit board 254 has a front board 253 and a rear board 255 disposed opposite to each other, the first opening 251 penetrates the front board 253 and the rear board 255 and penetrates an edge of the circuit board 254, the image capturing apparatus 200 includes a shielding member 260 disposed on the front board 253, and the shielding member 260 is used for preventing the power module 220 from interfering with electronic components on the main board 250. The edge of the shielding member 260 is provided with a notch 261, and the second connecting end 257 is located in the notch 261. Referring to fig. 8, the flexible circuit board 215 is folded from the back board 255 to the front board 253 and is fastened to the second connection end 257, so that the camera module 210 can be communicatively connected to the motherboard 250. The above arrangement causes the flexible circuit board 215 of the camera module 210 to turn over in the thickness direction of the image capturing apparatus 200, so that the size occupied by the flexible circuit board 215 in the length or width direction of the image capturing apparatus 200 can be reduced, thereby being beneficial to reducing the volume of the image capturing apparatus 200. In an embodiment, the first connection end 216 and the second connection end 257 are two terminals of a Board-to-Board connector (BTB) capable of being mated with each other, and the Board-to-Board connector is configured to facilitate standardization of the first connection end 216 and the second connection end 257 and communication connection between the camera module 210 and the motherboard 250.

The above structure can use the power module 220 to abut against the first connection end 216, so as to ensure the reliability of the electrical connection between the first connection end 216 and the second connection end 257. Referring to fig. 7 and 8, in an embodiment, the power module 220 is U-shaped and disposed on a side of the front panel 253, the power module 220 defines a second opening 221, and the power module 220 is sleeved on the lens barrel 213 through the second opening 221. With the above structure, the lens barrel 213 of the camera module 200 can be prevented from being stacked on the power module 220, thereby being beneficial to the thinning of the overall thickness of the image capturing apparatus 200. Referring to fig. 9, in other embodiments, the power module 220 may be provided with a second through hole 223 so that the power module 220 is substantially annular, and the lens barrel 213 is disposed in the second through hole 223, which is beneficial to the overall thickness reduction of the image capturing device 200. Referring to fig. 10, the power module 220 may also have an "L" shape and define a second right angle region formed by two substantially perpendicular portions of the power module 220, and the lens barrel 213 is disposed through the second right angle region. By providing the second right angle area on the power module 220 and disposing the lens barrel 213 in the second right angle area, the lens barrel 213 of the camera module 200 is prevented from being stacked on the power module 220, thereby facilitating the thinning of the overall thickness of the image capturing device 200.

The above structure facilitates the positioning of the image capturing apparatus 200 in the mounting groove 120 and prevents the image capturing apparatus 200 from easily coming out of the host side 100. The structure of matching the buckle 245 and the clamping groove 141 is also beneficial to the positioning of the image acquisition device 200 on the host end 100 after the image acquisition device 200 is overturned around the length direction of the host end 100. In an embodiment, one end of the buckle 245 protrudes out from the third side peripheral surface 237 or the fourth side peripheral surface 238, and an elastic member such as a spring may be connected to the other end of the buckle 245 to enable the buckle 245 to slide and stretch on the image capturing device 200.
