A mobile phone is a mobile terminal equipped with a cellular communication module.

Referring to FIGS. 1 to 3 , in one embodiment, the mobile terminal 10 is a smart phone. The mobile terminal 10 includes a host terminal 100 and an image acquisition device 200. The host terminal 100 is roughly in the shape of a rectangular block. The host terminal 100 has a front surface 121, a rear surface 123, and a side surface connected between the front surface 121 and the rear surface 123. The side surface includes a first side surface 125 and a second side surface 126 disposed opposite to each other, and a third side surface 127 and a fourth side surface 128 disposed opposite to each other. The first side surface 125 is connected to one end of the third side surface 127 and the fourth side surface 128, and the second side surface 126 is connected to the other end of the third side surface 127 and the fourth side surface 128. The host terminal 100 is provided with a mounting groove 130. In one embodiment, the mounting groove 130 runs through the first side surface 125 and the third side surface 127. A display screen 140 is provided on the front surface 121 of the host terminal 100. The host end 100 includes a display screen 140, and the displayable area of the display screen 140 constitutes all or part of the front surface 121. The displayable area of the display screen 140 can be used to display information and provide an interactive interface for the user to complete touch and other operations.

The image acquisition device 200 includes a camera module 210, and the camera module 210 has a light incident surface 211, and light can pass through the light incident surface 211 and be incident on the photosensitive element of the camera module 210. Referring to FIG. 4 at the same time, the image acquisition device 200 can be installed in the mounting slot 130 and can be removed from the mounting slot 130, and after the image acquisition device 200 is removed from the mounting slot 130, the image acquisition device 200 can be connected to the host end 100 by communication. The communication connection method can be wired communication or wireless communication. For example, after the image acquisition device 200 is removed from the mounting slot 130, it can be connected to the host end 100 by communication in the form of a cable, or it can be connected to the host end 100 by communication module. When the image acquisition device 200 is installed in the mounting slot 130, the image acquisition device 200 can have a first position and a second position. Referring to FIG. 2 and FIG. 3, in the first position, the image acquisition device 200 is accommodated in the mounting slot 130. 5 and 6 , in the second position, the light incident surface 211 is exposed on the side where the display screen 140 is located and the camera module 210 can communicate with the host end 100. After the light incident surface 211 is exposed, the user can make a video call or take a selfie through the image acquisition device 200.

In the mobile terminal 10, the image acquisition device 200 can be disassembled from the host end 100, and can be connected to the host end 100 after being disassembled. The user can perform multi-angle and multi-scene shooting or video recording operations through the image acquisition device 200, which is conducive to improving the user experience. After the image acquisition device 200 is disassembled from the host end 100, it can also be installed in the installation slot 130 of the host end 100 so that the image acquisition device 200 has a first position and a second position. In the first position, the image acquisition device 200 can be accommodated in the installation slot 130. In the second position, the light incident surface 211 of the camera module 210 can be exposed on the side where the display screen 140 is located and can be connected to the host end 100 for communication. The camera module 210 can perform the function of the front camera, thereby avoiding the front camera from occupying the area on the side where the display screen 140 is located, which is conducive to improving the screen-to-body ratio of the mobile terminal 10. For example, the mobile terminal 10 adopting the above structure can have a screen-to-body ratio of more than 85%, which is conducive to improving the user experience.

In one embodiment, when the image acquisition device 200 is located at the second position, the direction of the light incident surface 211 of the camera module 210 is consistent with the direction of the display screen 140, and at this time, the image acquisition device 200 can perform the function of the front camera. Referring to FIG. 7, in one embodiment, the image acquisition device 200 is removed from the installation slot 130 and then installed into the installation slot 130, and the image acquisition device 200 can also be located at the third position. In the third position, the direction of the light incident surface 211 is opposite to the direction of the display screen 140, and the light incident surface 211 is exposed on the side facing away from the display screen 140, and the camera module 210 can be connected to the host end 100 for communication. At this time, the image acquisition device 200 can perform the function of the rear camera, and the user can perform operations such as taking pictures and recording videos through the image acquisition device 200. The above structure does not need to set a rear camera on the host end 100, thereby saving the cost of the rear camera, and further saving the cost of the electronic components of the mobile terminal 10.

8 and 9, in one embodiment, the image acquisition device 200 is generally in the shape of a rectangular block, and has a front end face 251, a rear end face 253, and a side circumferential surface connected between the front end face 251 and the rear end face 253, and the side circumferential surface includes a first side circumferential surface 254 and a second side circumferential surface 255 disposed opposite to each other, and a third side circumferential surface 256 and a fourth side circumferential surface 257 disposed opposite to each other. The first side circumferential surface 254 and the second side circumferential surface 255 are respectively located at two ends of the width direction of the image acquisition device 200, and the third side circumferential surface 256 and the fourth side circumferential surface 257 are respectively located at two ends of the length direction of the image acquisition device 200.

Referring to FIG. 2 and FIG. 3 , a coordinate system is established with the length direction of the host end 100 as the X-axis, the width direction as the Y-axis, and the thickness direction as the Z-axis. The first side surface 125 and the second side surface 126 are respectively located at the two ends of the length direction (X-axis direction) of the host end 100, the third side surface 127 and the fourth side surface 128 are respectively located at the two ends of the width direction (Y-axis direction) of the host end 100, and the mounting groove 130 is located between the front surface 121 and the rear surface 123. With the above structure, the mounting groove 130 does not need to penetrate the rear surface 123 of the host end 100, so that the appearance integrity of the rear surface 123 side of the host end 100 can be maintained.

Referring to FIG. 3 , in the first position, the length direction of the image acquisition device 200 is parallel to the width direction of the host end 100. Referring to FIG. 5 and FIG. 6 , in the second position, the length direction of the image acquisition device 200 is parallel to the length direction of the host end 100. Referring to FIG. 10 , in another embodiment, when the image acquisition device 200 is in the first position, the length direction of the image acquisition device 200 is parallel to the length direction of the host end 100. Referring to FIG. 11 , in the second position, the length direction of the image acquisition device 200 is parallel to the width direction of the host end 100. The above structures can realize that the image acquisition device 200 is accommodated in the host end 100, and because the image acquisition device 200 is located at the corner of the host end 100, it is convenient for the user to apply force to the image acquisition device 200 through fingers, so as to facilitate the removal of the image acquisition device 200 from the mounting slot 130.

Furthermore, when the image acquisition device 200 is located at the first position, the direction of the light incident surface 211 of the camera module 210 can be the same as or opposite to the direction of the display screen 140. With the above arrangement, the light incident surface 211 of the image acquisition device 200 can be oriented toward the side where the display screen 140 is located so as to be installed in the installation slot 130, or the light incident surface 211 can be located at the side facing away from the display screen 140 and installed in the installation slot 130, thereby facilitating the image acquisition device 200 to be installed in the installation slot 130, thereby improving the convenience of use for the user.

8 and 9, the image acquisition device 200 may include a first connection end 220, and the first connection end 220 can be connected to the camera module 210 for communication. The host end 100 may include a second connection end (not shown) disposed in the mounting groove 130, and in the second position, the camera module 210 is connected to the second connection end through the first connection end 220, so that the camera module 210 can be connected to the host end 100 for communication. Further, one of the first connection end 220 and the second connection end is a male connector, and the other is a female connector.

Specifically, the first connection end 220 can be a Type-C type connector male head or a connector female socket, and the second connection head is correspondingly a Type-C type and matches the first connection end 220. When the first connection end 220 is a Type-C type, the image acquisition device 200 can be inserted into the second connection end of the host end 100 from the front or back, so that the direction of the light incident surface 211 is the same as or opposite to the direction of the display screen 140. The image acquisition device 200 can perform both the front camera function and the rear camera function. In other embodiments, the first connection end 220 can also be a Micro USB type connector male head or a connector female socket, and the second connection end matches the first connection end 220. In the embodiment where the first connection end 220 is a Micro USB type, when the image acquisition device 200 is inserted into the second connection end of the host end 100, the direction of the light incident surface 211 of the camera module 210 is the same as the direction of the display screen 140, and the image acquisition device 200 can perform the function of front-end camera, and the side of the display screen 140 of the host end 100 does not need to be provided with a front camera, so that a high screen-to-body ratio of the host end 100 can be achieved. It can be understood that the first connection end 220 can also be a cylindrical plug structure, and the second connection end is a jack matching the first connection end 220. The first connection end 220 can be inserted into the second connection end and communicated with the host end 100. The above structure can also realize the multiplexing of the front and rear of the image acquisition device 200 and improve the user experience.

Referring to Figures 12 and 13, the image acquisition device 200 may include a power module 230 and a first wireless communication module, and the power module 230 can be electrically connected to the camera module 210 and the first wireless communication module respectively. The host end 100 includes a second wireless communication module and a third wireless communication module, the second wireless communication module is used to communicate with the first wireless communication module, and the third wireless communication module is used to communicate with an external device such as a base station or other mobile terminal 10. After the camera module 210 is removed from the mounting slot 130, the camera module 210 can communicate with the second wireless communication module through the first wireless communication module. Specifically, the power module 230 may include a lithium battery that can be repeatedly charged and discharged, and the power module 230 can power the camera module 210 and the first wireless communication module. In other embodiments, the power module 230 may also include a fuel cell, etc. It is understandable that a battery can be set in the host end 100, and the battery can be used to power the display screen 140 and electronic components such as a processor inside the host end 100.

The first wireless communication module and the second wireless communication module can realize short-range communication, and both adopt the same communication protocol. For example, the first wireless communication module and the second wireless communication module can both be Bluetooth communication modules, or both are WiFi (Wireless Fidelity) communication modules, or both are ZigBee communication modules, or both are NFC (Near Field Communication) communication modules. When the image acquisition device 200 is detached from the host end 100, the communication connection between the image acquisition device 200 and the host end 100 can be realized through the first wireless communication module and the second wireless communication module. The user can hold the image acquisition device 200 to shoot at multiple angles and multiple scenes, and transmit the captured data to the host end 100. For example, the user can hold the image acquisition device 200 with one hand and the host end 100 with the other hand. Through the image acquisition device 200, images of various positions and angles can be captured, and the images can be viewed through the display screen 140 of the host end 100. For another example, the user can place the image acquisition device 200 at a certain place and view the images captured by the image acquisition device 200 through the host end 100 at another place.

It is understandable that in the embodiment where the image acquisition device 200 includes a power module 230 and a first wireless communication module, and the host end 100 includes a second wireless communication module and a third wireless communication module, the first connection end 220 and the second connection end can be omitted. When the image acquisition device 200 is in the second position, the communication connection between the host end 100 and the image acquisition device 200 can be realized through the first wireless communication module and the second wireless communication module, and the above structure can also improve the screen ratio of the host end 100. It is understandable that in the embodiment where the image acquisition device 200 includes a power module 230, a third connection end (not shown) can be set in the installation slot 130, and the third connection end can be a Type-C type connector male head or connector female socket, or a Micro USB type connector male head or connector female socket, and the type of the third connection end matches the type of the first connection end 220. In the first position, the first connection end 220 can be inserted into the third connection end so that the image acquisition device 200 can be electrically connected to the host end 100, and the host end 100 can charge the power module 230 in the image acquisition device 200. In one embodiment, the third connection end can also form a snap fit with the first connection end 220 so that the image acquisition device 200 can be reliably positioned on the host end 100 when in the first position, preventing the image acquisition device 200 from easily escaping from the host end 100.

It is understandable that the power module 230, the first wireless communication module, and the second wireless communication module are not necessary. When the image acquisition device 200 is removed from the installation slot 130 and then installed into the installation slot 130 so that the image acquisition device 200 is located in the second position, the battery in the host end 100 can be used to power the image acquisition device 200, and the processor in the host end 100 can also be used to process the data captured by the image acquisition device 200. The image acquisition device 200 can also achieve a large screen ratio of the host end 100, which will not be repeated here.

12 and 13, the image acquisition device 200 may include a housing 250 and a mainboard 260, and a front end face 251, a rear end face 253, and a side peripheral face are located on the housing 250. A light hole 270 is provided on the housing 250, and the light hole 270 passes through the front end face 251. The power module 230, the mainboard 260, and the camera module 210 are accommodated in the housing 250, and the light incident surface 211 is exposed from the light hole 270. The mainboard 260 is stacked on the power module 230, and the mainboard 260 can be electrically connected to the power module 230, and the mainboard 260 can be respectively connected to the camera module 210 and the first wireless communication module for communication.

In one embodiment, the power module 230 is L-shaped and defines a first right angle area 231, the first right angle area 231 is formed by two parts of the power module 230 that are approximately at right angles, and the camera module 210 is disposed in the first right angle area 231. The power module 230 of the above structure can avoid stacking the camera module 210 on the power module 230, thereby reducing the overall thickness of the image acquisition device 200. In one embodiment, the main board 260 is L-shaped and defines a second right angle area 261, the second right angle area 261 is formed by two parts of the main board 260 that are approximately at right angles, and the camera module 210 is disposed in the second right angle area 261, and the main board 260 of the above structure can also avoid stacking the main board 260 on the camera module 210, thereby reducing the overall thickness of the image acquisition device 200.

Meanwhile, referring to FIG. 14 , in other embodiments, a first through hole 233 is provided on the power module 230 so that the power module 230 is roughly annular, and the camera module 210 is inserted into the first through hole 233. The power module 230 of the above structure can avoid stacking the camera module 210 on the power module 230, thereby reducing the overall thickness of the image acquisition device 200. In other embodiments, a second through hole 263 is provided on the mainboard 260 so that the mainboard 260 is roughly annular, and the camera module 210 is inserted into the second through hole 263. The mainboard 260 of the above structure can also avoid stacking the mainboard 260 on the camera module 210, thereby reducing the overall thickness of the image acquisition device 200.

In the above embodiment, the mounting groove 130 passes through the first side surface 125 and the third side surface 127. It is understood that in other embodiments, the mounting groove 130 may also pass through the first side surface 125 and the fourth side surface 128. In other embodiments, the mounting groove 130 may also pass through one of the third side surface 127 and the fourth side surface 128 and pass through the second side surface 126, for example, the mounting groove 130 may pass through the second side surface 126 and the third side surface 127, or the mounting groove 130 passes through the second side surface 126 and the fourth side surface 128. The above settings are all conducive to achieving a high screen-to-body ratio of the mobile terminal 10, and will not be repeated here.

15 to 17 , in another embodiment, the mounting groove 130 penetrates the third side surface 127 and the fourth side surface 128 and the mounting groove 130 penetrates the first side surface 125. The above arrangement allows the two ends of the image acquisition device 200 to be exposed from the third side surface 127 and the fourth side surface 128 of the host end 100, respectively, so as to facilitate the removal of the image acquisition device 200 from the host end 100. It is understandable that the mounting groove 130 may also penetrate the third side surface 127 and the fourth side surface 128 and the mounting groove 130 may penetrate the second side surface 126.

Further, in the embodiment where the mounting groove 130 passes through the third side surface 127 and the fourth side surface 128, when in the first position, the image acquisition device 200 can be pushed out of the mounting groove 130 from the side where the third side surface 127 is located or from the side where the fourth side surface 128 is located. Specifically, the image acquisition device 200 can be pushed out of the mounting groove 130 by pushing the image acquisition device 200 from the side where the third side surface 127 is located or by pushing the image acquisition device 200 from the side where the fourth side surface 128 is located, thereby facilitating the removal of the image acquisition device 200 from the host end 100.

In the embodiment of the present application, the mobile terminal 10 may include components such as a memory, an input unit, a sensor, an audio circuit, a processor, a fingerprint module, and a battery.

The memory can be used to store software programs and modules. The processor executes various functional applications and data processing of the mobile terminal 10 by running the software programs and modules stored in the memory. The memory can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile terminal 10 (such as audio data, a phone book, etc.), etc. In addition, the memory can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

The input unit can be used to receive input digital or character information, and generate key signals related to user settings and function control of the mobile terminal 10. Specifically, the input unit may include a touch panel and other input devices. A touch panel, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by a user using a finger, stylus, or any other suitable object or accessory on or near the touch panel), and drive corresponding connection devices according to a pre-set program.

Optionally, the touch panel may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch direction, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, and converts it into contact coordinates, and then sends it to the processor, and can receive and execute commands sent by the processor. In addition, the touch panel can be implemented using various types such as resistive, capacitive, infrared and surface acoustic wave. In addition to the touch panel, the input unit may also include other input devices. Specifically, other input devices may include but are not limited to one or more of a physical keyboard, function keys (such as volume control buttons, switch buttons, etc.), a trackball, a mouse, a joystick, etc.

The display screen 140 may include a display panel. Optionally, the display panel may be configured in the form of a liquid crystal display unit (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, the touch panel may cover the display panel. When the touch panel detects a touch operation on or near it, it is transmitted to the processor to determine the type of touch event, and then the processor provides a corresponding visual output on the display panel according to the type of touch event. It is understandable that the touch panel can be regarded as a part of the display screen 140, that is, the display screen 140 includes a display panel and a touch panel.

The audio circuit, the speaker and the microphone can provide an audio interface between the user and the mobile terminal 10. The audio circuit can transmit the received audio data to the speaker after converting the received audio data into an electrical signal, which is converted into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit and converted into audio data, and then the audio data is output to the processor for processing, and then sent to another mobile terminal 10 through the radio frequency circuit, or the audio data is output to the memory for further processing.
