In one embodiment, the body 100 includes a display screen 101. The display screen 101 includes a displayable region for image information display. The body 100 may further include a cover glass covering the display screen 101 for protecting the display screen 101, where a side of the cover glass facing away from the displayable region of the display screen 101 constitutes all or part of the front surface 110. The body 100 may further include a middle frame 102, two opposite end surfaces of the middle frame 102 are a front surface 110 and a rear surface 120 of the body 100, an outer wall surface of the middle frame 102 is a side surface 130 of the body 100, and the display screen 101 is fixed on the front surface 110 of the middle frame 102. The rear surface 120 of the middle frame 102 may carry other components of the mobile terminal 10, such as mounting assemblies 200, control components, power components, and the like. In one embodiment, the body 100 may further include a rear cover 103, the rear cover 103 being coupled to the rear surface 120 of the middle frame 102 to seal the above-described various components mounted to the rear surface 120 of the middle frame 102.

In one embodiment, the body 100 defines a receiving slot 1001. In one embodiment, the receiving slot 1001 is opened on the second side 132 of the body 100. Further, the receiving slot 1001 may be opened in the middle of the second side 132, that is, the receiving slot 1001 is located between the front surface 110 and the rear surface 120, and the receiving slot 1001 may also be opened on the edge of the second side 132 close to the rear surface 120. Of course, in other embodiments, the accommodating groove 1001 may be opened on the first side 131 of the body 100, i.e. the long side of the mobile terminal 10.

Referring to fig. 2 and 3, the body 100 is provided with a magnetic body 300, and the magnetic body 300 can generate a magnetic field in the vicinity thereof. The mounting assembly 200 includes a mounting base 210 and a magnetic field sensor 220 disposed on the mounting base 210, the magnetic field sensor 220 may be, for example, a hall sensor. The mounting base 210 is disposed in the receiving slot 1001 and can move in and out of the receiving slot 1001, and in the process that the mounting base 210 moves in and out of the receiving slot 1001, the mounting base 210 can drive the magnetic field sensor 220 to move relative to the magnetic body 300, that is, the mounting base 210 drives the magnetic field sensor 220 and the magnetic body 300 to generate relative displacement, so as to determine the position of the mounting base 210 by receiving the magnetic field strength of the magnetic body 300. That is, in the process that the mounting seat 210 enters and exits the receiving slot 1001, when the magnetic field sensor 220 gradually approaches the magnetic body 300, the magnetic field strength of the magnetic body 300 received by the magnetic field sensor 220 gradually increases, and when the magnetic field sensor 220 gradually moves away from the magnetic body 300, the magnetic field strength of the magnetic body 300 received by the magnetic field sensor 220 gradually decreases, so that the position of the mounting seat 210 can be determined according to the magnetic field strength received by the magnetic field sensor 220. Since the magnetic field sensor 220 is not the magnetic body 300, i.e., the magnetic body 300 is fixed, and the magnetic field generated by the magnetic body 300 is fixed, the magnetic body 300 does not generate a changing magnetic field due to movement, and the interference of the magnetic body 300 to other components is reduced.

In an embodiment, referring to fig. 2 and 3, the mobile terminal 10 includes a receiver 400 connected to the body 100, the receiver 400 has magnetic steel, and the magnetic steel can form the magnetic body 300 of the embodiments of the present application. Alternatively, in the present invention, a magnet connected to the main body 100 may be provided directly in a range in which the magnetic field sensor 220 can sense the magnetic field, and used as the magnetic body 300. Referring to fig. 4, in an embodiment, when the magnetic steel in the receiver 400 is not in the sensing range of the magnetic sensor 220, the magnetic body 300 may be a magnet, the magnetic body 300 is connected to the wall of the accommodating slot 1001, and the magnetic body 300 is provided with a through hole for the mounting base 210 to movably penetrate through. In one embodiment, the groove wall of the housing groove 1001 defines an annular groove 1002, and the side periphery of the magnetic member 300 is embedded in the annular groove 1002. As described above, by reasonably arranging the components of the mobile terminal 10, the receiver 400 is disposed close to the accommodating slot 1001, and the magnetic steel in the receiver 400 can be used as the magnetic body 300, so that the extra magnetic body 300 does not need to be disposed, which is beneficial to the development of miniaturization of the mobile terminal 10. In addition, even if the additional magnetic member 300 is provided, if the magnetic member 300 is connected to the wall of the receiving groove 1001, the magnetic member 300 is assembled as a part of the middle frame 102, and does not occupy the internal space of the mobile terminal 10.

Referring to fig. 2 and 3, in one embodiment, the mounting assembly 200 further includes a functional device 230 disposed on the mounting base 210. In an embodiment, the functional device 230 includes a camera, the functions of taking a picture and taking a video of the camera can provide video call and shooting for the mobile terminal 10, and the light incident surface of the camera can be provided with dustproof glass to shield dust. It is understood that in other embodiments, the functional device 230 may further include a light sensor, a flash, etc. for assisting the camera to shoot, or other functional devices independent of the shooting function of the camera, such as: iris recognition module, face recognition module, proximity sensor, ambient light sensor, microphone, fingerprint module, etc., but not limited thereto.

In the process that the mount 210 enters and exits the receiving slot 1001, the mount 210 can move from a first position (shown in fig. 2) to a second position (shown in fig. 3) with the camera, when the mount 210 is located at the first position, the camera is received in the receiving slot 1001, and when the mount 210 is located at the second position, the image capturing surface (i.e., the light incident surface) of the camera is located outside the receiving slot 1001, that is, the image capturing surface of the camera is exposed out of the receiving slot 1001. Thus, when the camera is needed to shoot, the mounting seat 210 carries the camera to move out of the accommodating groove 1001, so that shooting is performed, and after shooting is completed, the mounting seat 210 carries the camera to move into the accommodating groove 1001, so that the space of the side where the display screen 101 is occupied by the camera can be eliminated, the coverage rate of the display screen 101 on the front surface 110 is increased, and the screen occupation ratio of the display screen 101 is improved.

In an embodiment, when the mounting base 210 is in the second position, the image capturing surface of the camera is exposed to the side where the display screen 101 is located, so that the camera can be used as a front camera, and the screen occupation ratio of the side where the display screen 101 is located is increased. Or, when the mounting base 210 is located at the second position, the image collecting surface of the camera is exposed at one side of the rear cover 103, so that the camera can be used as a rear camera, and at this time, a channel for the camera to collect light does not need to be formed in the rear cover 103, thereby ensuring the integrity of the rear cover 101.

In one embodiment, the mounting assembly 200 includes a driver 240, the driver 240 may be a motor, for example, and the driver 240 is connected to the mounting base 210 and can drive the mounting base 210 to extend and retract into and out of the receiving slot 1001. It is understood that in other embodiments, the driver 240 is coupled to the mounting base 210 and can rotate the mounting base 210 into and out of the receiving slot 1001. The embodiments of the present application do not limit the specific manner in which the mounting base 210 enters and exits the accommodating groove 1001. In addition, the mounting base 210 can be driven to move into and out of the accommodating groove 1001 by a manual driving method, and the driver 240 can be omitted. Referring to fig. 2, when the mounting base 210 is in the first position, the mounting base 210 is received in the receiving slot 1001 and the upper end surface 211 of the mounting base 210 is flush with the side surface 130 (specifically, the second side surface 132), so that the integrity of the appearance of the mobile terminal 10 can be ensured.

In an embodiment, a main board 500 is disposed in the main body, the mounting assembly 200 includes a flexible connector 250, and the magnetic field sensor 220 is electrically connected to the main board 500 through the flexible connector 250, and the flexible connector 250 may be a flexible circuit board, for example. Of course, the flexible connector 250 may also be, but is not limited to, a flexible conductive cloth or a flexible conductive tape. Connect magnetic field inductor 220 with mainboard 500 through flexible connector 250, compare and be connected magnetic field inductor 220 and mainboard 500 through rigid connector, can avoid the phenomenon of jamming to appear in the mount pad 210 motion process, and then influence mount pad 210 and normally pass in and out accepting groove 1001. Of course, the functional device 230 such as a camera, a flash, etc. may also be connected to the main board 500 through a flexible circuit board.

In an embodiment, the functional device 230 such as a camera, a flash, etc. and the magnetic field sensor 220 may also implement wireless data transmission with the chip disposed on the mounting base 210 and the main board of the mobile terminal 10. In the following description, only the magnetic field sensor 220 is taken as an example, in an embodiment, the body 100 includes a first uhf communication chip (not shown), the mounting assembly 200 includes a second lf communication chip (not shown) disposed on the mounting base 210, the magnetic field sensor 220 can be communicatively connected to the second lf communication chip, and the second lf communication chip is paired with the first lf communication chip when the mounting base 210 is in the second position, so that the first lf communication chip can be communicatively connected to the second lf communication chip.

The first extremely high frequency communication chip and the second extremely high frequency communication chip are both extremely high frequency communication chips. The extremely high frequency communication chip is an IC (integrated circuit) chip in which an EHF (extremely high frequency) antenna is packaged, and when the two extremely high frequency communication chips are close enough, pairing can be completed to perform wireless communication. An example of an extremely high frequency communication chip is an EHF common link chip. The terms "common link chip," "common link chip package," and "EHF comm-link chip package" are used to refer to an EHF antenna embedded in an IC package. Examples of the chip for very high frequency communication can refer to the information described in the U.S. patent application publication nos. 2012/0263244 and 2012/0307932, and also refer to the information disclosed in chinese patent publications CN103563166A and CN 104145380A.

An example of an extremely high frequency communication chip can be found in the chinese granted patent publication No. CN 105264785B. The image collector of the camera equipped with the extremely high frequency communication chip (second extremely high frequency communication chip) can realize high-speed wireless transmission of data (for example, a transmission speed up to 6 GB/s) based on a high carrier frequency (for example, 60GHz) with the main board of the mobile terminal 10 equipped with the extremely high frequency communication chip (first extremely high frequency communication chip).

It can be understood that the high carrier frequency-based near field communication has the advantages of low power consumption, small volume, high transmission rate, non-contact transmission and the like, can also realize the function of a plug-and-play module, can greatly improve the signal integrity, support more flexible system realization, reduce the standby power consumption, increase the bandwidth amplitude and the safety of data transmission, and is compatible with the support of high-speed video signals and the like.

It will be appreciated that the high carrier frequency may be a carrier frequency that enables high speed wireless transmission of data. The high carrier frequency may be a specific carrier frequency, or may be a carrier frequency band, for example, 30GHz to 300GHz, which is not specifically limited in this embodiment of the present application. For example, the high carrier frequency is 60 GHz.

In one embodiment, referring to fig. 5, the main board 500 is provided with a controller 510, and when the mounting base 210 is in the first position and the second position, the controller 510 can control the driver 240 to turn off according to the intensity of the magnetic field sensed by the magnetic field sensor 220. Specifically, when the mounting base 210 is located at the first position, the magnetic field sensor 220 is far away from the magnetic body 300, the magnetic field strength of the magnetic body 300 that can be sensed by the magnetic field sensor 220 is a first preset value, when the mounting base 210 is located at the second position, the magnetic field sensor 220 is close to the magnetic body 300, the magnetic field strength of the magnetic body 300 that can be sensed by the magnetic field sensor 220 is a second preset value, the second preset value is greater than the first preset value, and the first preset value and the second preset value can be stored in advance. Therefore, in the whole process that the mounting base 210 enters and exits the accommodating slot 1001, the controller 510 can obtain the magnetic field strength value detected by the magnetic field sensor 220, and if the detected magnetic field strength value is matched with the first preset value or the second preset value, the controller 510 can timely control the driver 240 to stop driving the mounting base 210 to continue moving, so as to avoid the damage caused by interference between other devices and the mounting base 210 due to excessive movement.

An example of a possible way in which the driver 240 controls the mount 210 is now given:

for example, a trigger key may be provided on the side 130 of the body 100. The trigger key connects to the main board 500 within the mobile terminal 10. When the user presses or touches the trigger key, the trigger key sends a trigger signal to the processor (i.e., the controller 510) on the motherboard 500, and the processor controls the driver 240, so that the mounting base 210 moves out of the receiving slot 1001 or retracts into the receiving slot 1001 under the control of the driver 240. For example, in an embodiment, when a user needs to use the camera to shoot, the user presses the trigger key once, so that the mounting base 210 moves to the outside of the accommodating slot 1001 to a specified position (for example, a second position) under the control of the driver 240, at this time, the controller 510 controls the driver 240 to stop working due to acquiring the second preset value sensed by the magnetic field sensor 220, and the user can use the camera to perform operations such as video chat or self-timer. When the user does not need to use the camera to shoot, the user can press the trigger key once again to make the mounting base 210 retract into the accommodating groove 1001 under the control of the driver. Of course, the number of the trigger keys may be two, one trigger key is used to move the mounting base 210 out of the receiving slot 1001 to a designated position (for example, the second position) under the control of the driver 240, and the other trigger key is used to retract the mounting base 210 into the receiving slot 1001 under the control of the driver 240. When the mounting base 210 is retracted to the first position under the control of the driver 240, the controller 510 controls the driver 240 to stop working by acquiring the first preset value sensed by the magnetic field sensor 220.

In other embodiments, the trigger key may also be a touch icon disposed on the display screen 101, and clicking the touch icon can send a related touch signal to a processor on the motherboard, and the processor receives the touch signal and executes a corresponding command according to the control signal, so that the driver 240 drives the mounting base 210 to move out of the accommodating slot 1001 or retract into the accommodating slot 1001. For example, the trigger keys may be a start shooting icon and an end shooting icon provided in the display screen 101. When the icon starts to be shot by touch, the icon starts to be shot and sends a first trigger signal to the processor of the motherboard, and the processor receives the first trigger signal and controls the driver 240 to drive the mounting seat 210 to rotate to a specified position (for example, a second position) outside the accommodating groove 1001, so that the camera can shoot under the shooting signal, and at this time, the controller 510 controls the driver 240 to stop working due to acquiring a second preset value sensed by the magnetic field sensor 220. When the user touches the end icon, the end icon sends a second trigger signal to the processor of the motherboard, the processor receives the second trigger signal and controls the driver 240 to drive the mounting seat 210 to retract into the accommodating groove 1001 to the first position, and at this time, the controller 510 controls the driver 240 to stop working due to the fact that the first preset value sensed by the magnetic field sensor 220 is obtained.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
