Detailed ways

The preferred embodiments of the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the embodiments of the present disclosure, and are not used to limit the embodiments of the present disclosure.

Example 1

As shown in Figures 1 to 3, they are schematic diagrams of the structure of a mobile terminal with a pop-up access accessory cover device of this disclosure. As shown in the figure, the accessory case is used to house the mobile terminal, and the accessory case is provided with components for expanding the information transmission function.

As can be seen from the figure, the device for pop-up access to the accessory case according to the embodiment of the present disclosure includes: a camera mechanism that is installed on a mobile terminal and can be popped up; a pop-up mechanism connected to the camera mechanism and used to eject the mobile terminal; and The signal access area is arranged on the exposed part of the camera mechanism that pops up on the mobile terminal, and the signal access area is used to connect the component on the accessory cover for extending the information transmission function.

In an exemplary embodiment, the signal access area is located on the front side on the same side as the camera of the camera mechanism and/or on the side parallel to the front side and/or on the back side opposite to the camera. The front side of the camera mechanism on the same side as the camera and/or the back side of the camera back side is provided with a printed circuit board or a flexible circuit board, and the circuit board is connected to multiple board connectors. The plurality of board-board connectors include a front-end board connector for electrically connecting the accessory case to expand the information transmission function part and the internal circuit board of the mobile terminal. The front-end board connector includes one or more of 5G antenna module signal connectors, power and control signal connectors, earphone audio signal connectors, and USB high-speed digital signal connectors.

Specifically, the present disclosure adds a signal access area 4 for electrical connection with the accessory cover 100 to the exposed part 2 of the camera mechanism of the mobile terminal 1 to connect the accessory cover for signal access for extending the information transmission function. To the body of the mobile terminal 1.

In an exemplary embodiment, the signal access area may be located on the front side on the same side as the camera 3 of the camera mechanism and/or on the side parallel to the front side and/or on the back side opposite to the camera.

As shown in Figure 1, the signal access area 4 is located on the parallel side of the front of the camera 2, and the front of the camera 2 is in the same direction as the front screen 5 of the mobile terminal; as shown in Figure 2, the signal access area is located on the back of the camera. The back of the camera 2 is in the same direction as the back fuselage 6 of the mobile terminal; as shown in FIG. 3, the signal access area is located on the parallel side and the back of the front of the camera.

If the signal access area is located on the parallel side of the front of the camera 3, it needs to be extended horizontally in the support structure of the camera. Usually, a circuit board with structural support is added in the horizontal parallel area of the camera, and the circuit board has various signal connectors or connection points, as shown in Figure 1. If the signal access area is located on the back of the camera 3, the support structure of the camera does not need to expand horizontally. However, the longitudinal direction of the camera requires a moderate increase in thickness due to the placement of a circuit board for signal connection. The increase in thickness should not exceed the surface of the back shell of the mobile terminal. If there are signal access areas on the front and back of the camera, connection signals of different properties can be reasonably allocated on the two sides.

Figure 8 shows a schematic structural diagram of a specific embodiment of the camera mechanism in the device. The pop-up device adds a structurally supported circuit board 36 with classified signal connectors at the side-by-side position of the cameras. The circuit board can be a PCB (Printed Circuit Board) hard board or an FPC soft board. Because 5G millimeter-wave intermediate frequency signals and Sub6GHz radio frequency signals must be passed through, the circuit boards and signal connectors need to be low-impedance, using MPI (Modified Polyimide) and LCP (Liquid Crystal Polymer) High-molecular polymer) material is preferred.

The connectors on the circuit board are divided into four categories according to signal classification, namely 5G antenna module (compatible with 5G antenna) signal connector 37, power and control signal connector 21, earphone audio signal connector 38, and USB high-speed digital signal Connector 39. At the same time, these connectors can also be generally divided into front-end board connectors and back-end board connectors. The front-end board connector is used to connect a multifunctional accessory case including 5G antenna, USB port and earphones. The back-end board connector is used to connect various transmission cables connected to the internal circuit board 33 of the mobile terminal (such as 5G radio frequency signal cable 34, headset, USB, power and control signal cable 32, camera signal cable 31, etc.) Or FPC soft board for transmission purposes.

Therefore, there are two 5G antenna modules (compatible with 5G antennas) signal connectors 37, one 5G antenna module is used as a front-end connector for signal connection with a multifunctional accessory case with 5G antenna, and the other 5G antenna module is used as a back-end connector for signal connection Connect to the 5G RF signal cable 34 (5G millimeter-wave intermediate frequency signals and Sub 6GHz radio frequency signals are available. Because 5G millimeter-wave intermediate frequency signals require high transmission and come from the antenna module, they are collectively referred to as radio frequency signals together with the Sub 6GHz signal) and pass through the The cable is finally connected to the internal circuit board of the mobile terminal. However, the IF signal of the millimeter wave antenna module and the Sub6GHz signal have a large difference in transmission impedance after all. If you share a connector and cable to transmit signals, you must consider the separate transmission of the two types of signals inside the cable, and the transmission lines are quickly separated after the signals reach the circuit board of the mobile terminal. From the perspective of the optimal transmission effect, it is to further increase the connector to separate the two types of signal transmission.

The power and control signal connector, the earphone audio signal connector, and the USB high-speed digital signal connector are all used as front-end connectors, which are used to connect to the corresponding functional signals on the accessory case, but when connected to the internal circuit board of the mobile terminal, this The three types of signals are routed through the circuit board to a unified back-end connector, namely the earphone, USB, power and control signal connector 35, and then correspondingly connected via the earphone, USB, power and control signal cable 32.

FIG. 8 also shows a schematic diagram of an ejection mechanism used to partially eject the camera mechanism of the mobile terminal in the device of this embodiment. It can be seen from the figure that the bottom of the camera mechanism is connected with the ejection mechanism, and the ejection mechanism includes:

The electric motor 28 drives the screw 24 to rotate through the coupling 27 to drive the linked screw pair 26 to move up and down, and the camera mechanism is driven by the linked screw pair 26 on the right side of the lower support rod 25 to also move up and down synchronously. After the upper limit structure 22, the camera can be entirely exposed outside the casing of the mobile terminal. In this way, the signal access area side by side with the camera is also exposed as a whole. When the accessory case is used, the signal connection of the accessory case and the circuit board of the mobile terminal can be realized, thereby realizing the expansion of the 5G signal network of the mobile terminal, and simultaneously realizing wired headset and extended USB port access.

Fig. 8 The ejection mechanism of the camera has a spring 29 for buffering the external down force after the camera is ejected to avoid damage to the camera mechanism by external impact; at the same time, a lower limit structure 30 is installed on the left support rod at the bottom of the camera mechanism to ensure that the camera mechanism is limited. Displacement within the range.

It should be noted that FIG. 8 shows a schematic diagram of the camera ejection mechanism. Of course, the camera pop-up mechanism can be implemented in other ways. The core of the present disclosure is that the pop-up camera position adds a signal access area that can be connected to a multifunctional accessory case with a 5G antenna (of course, the signal access area can also be set in Figure 4). Any other suitable locations not shown). In the connection area, a circuit board with front and rear signal connectors is placed for signal transfer, so that the functional signals of the multifunctional accessory case with 5G antenna can be effectively connected to the mobile terminal.

When using the device of the present disclosure, the circuit board of the mobile terminal needs to reserve a connector and related circuits for introducing the accessory set signal.

The mobile terminal accesses the signal of the accessory case through the exposed part of the camera mechanism, which can avoid the process complexity and appearance damage caused by the implantation of the signal conductive metal body in the case that is traditionally caused when the signal is accessed from the body case.

Example 2

As shown in FIG. 4 and FIG. 5, the schematic diagrams of the front and the back of the accessory case for use with the above-mentioned mobile terminal of this embodiment are respectively. The accessory case of the present disclosure includes: a body 100 for placing a mobile terminal thereon; a hollowed-out area 107 provided on the body for lifting and moving the exposed part of the camera mechanism of the mobile terminal; and a body 100 provided on the body for lifting and moving the exposed part of the camera mechanism of the mobile terminal. A component that is electrically connected to the signal access area on the camera mechanism to expand the information transmission function.

In an exemplary embodiment, the component that extends the information transmission function includes one or more of 5G antenna or antenna module signal, earphone signal, and USB signal, and the body is provided with a heat dissipation device for the 5G antenna or antenna module. Thermally conductive layer.

Specifically, as shown in Figures 4 and 5, taking the accessory case signal access area located at the same direction and parallel side of the camera as an example, the multifunctional accessory case with 5G antenna is fully displayed from two angles of the front and the back.

The accessory case body 100 is U-shaped, and the U-shaped interior can wrap the mobile terminal 1. For example, the main body 100 is provided with a USB port 105, a front camera hole 104, an earphone hole 103, a camera hole 102, a hollow area 107 for the exposed part of the camera mechanism, and a rear camera hole 122.

In an exemplary embodiment, the top forehead space of the accessory case is significantly larger than the bottom space. In design, the height of the top forehead is slightly larger than the height of the exposed part 2 of the camera mechanism of the mobile terminal after popping up, and the width is slightly larger than the width of the mobile terminal. In this way, the accessory case can have sufficient space for embedding the USB connector, earphone body, accessory case signal access board, and related signal connection cables (the cables are not shown in the figure). At the same time, the hollowed-out area is used to accommodate the lifting and lowering of the pop-up camera mechanism. Correspondingly, the front face of the forehead position is provided with a front camera hole, and the side of the forehead position is provided with an earphone port and a USB port on the top.

The back and side edges of the accessory case are used to place millimeter

wave antenna modules

112, 114, 116, 119 and

Sub 6GHz antennas

113, 110, 117, 120 or antenna brackets for extending 5G network usage. Because the millimeter wave antenna module consumes a lot of power when working, it is necessary to add a large area of heat dissipation layer inside the back of the accessory case. There is also a rear camera window or transparent area 121 on the back of the accessory case. This area can be determined according to the number of rear cameras. Other components not shown in the figure, such as fingerprint recognition, flashlight, etc., can be exposed in the open window or transparent area of the rear camera.

The millimeter wave antenna module in the accessory case is AiM, and the inside is a millimeter wave antenna array and a radio frequency chip; the Sub 6GHz antenna is FPC (Floppy Printed Circuit, soft printed circuit board) or LDS (Laser Direct Structuring, laser Direct molding) form.

Because the signal of a single millimeter wave antenna module is susceptible to interference, the communication quality is usually ensured by switching the working modules according to the signal strength by increasing the layout at different positions. The number 4 shown in the figure can actually be increased or decreased as needed. Sub 6GHz antennas are usually 4*4MIMO, so the number of 4 is the normal requirement. Regardless of whether it is a millimeter wave antenna module or a Sub 6GHz antenna, in terms of the location of the accessory cover, when considering its own transmission performance requirements, it is also necessary to consider avoiding the antenna location of the mobile terminal. Due to the numerous antennas of 5G mobile terminals, it is difficult to avoid them. Therefore, the position of the SIM card of the terminal body, the periphery of the top ejection device, and the periphery of the USB port can be considered.

The size of the accessory cover needs to meet the space requirements of the millimeter wave antenna module (typical size 19mm*5mm*1.8mm, which can be further reduced to 19mm*3.5mm*0.6mm or even smaller with technological development) and the area requirements of the Sub 6GHz band antenna ( The length of the Sub6GHz antenna is between 1.5cm and 2.5cm, and the length of some frequency bands will exceed the length of the compact millimeter wave antenna module. If the LDS (Laser Direct Structuring Technology) process is changed, the size can be further reduced). In order to reduce the thickness of most of the area of the accessory cover, the millimeter wave antenna module can be preferably placed at the side of the accessory cover corresponding to the mobile terminal or only partially thickened where there is the millimeter wave antenna module.

The accessory cover is used to fully consider the heat dissipation path and material of the millimeter wave antenna module for heat dissipation. Due to the electromagnetic interference sensitivity of the millimeter wave to the heat dissipation material, it is necessary to select the ceramic material close to the surface of the millimeter wave module radio frequency chip (the ceramic material and the radio frequency chip can be filled with thermal grease) for conduction and heat dissipation, that is, the

heat conduction layer

111, 109, 115, 118, 123. Furthermore, a heat-conducting layer of sufficient area and sufficient length (there are 4 corresponding to each millimeter wave antenna module in FIG. 7) conduct heat to the large-area heat dissipation layer on the accessory cover and away from the module. The main body of the heat dissipation layer can be a large-area high thermal conductivity metal foil or a heat dissipation film (typically graphite) or a phase change material or direct heat pipe liquid cooling for heat dissipation, or a composite of several.

The 5G antenna or antenna module signal, headphone signal and USB signal of the accessory case can be reliably connected to the exposed part of the camera mechanism through the board connector, magnetic connector and shrapnel connector on the signal access board. The signal access area located on the side or back of the camera or on both sides of the camera realizes the reliable access of the signals of the various information transmission functions on the accessory cover to the mobile terminal.

However, since the signal connection position is close to the camera and the mechanical structure interference source, in order to reduce the difficulty of electromagnetic compatibility processing, it is preferable to use a low-impedance board connector to realize the signal connection, and fully consider the electromagnetic shielding measures outside the connector.

Because there are 5G antennas or antenna modules that require low-loss attachment materials inside the accessory cover, the large-area body of the accessory cover is preferably ceramic, leather, plastic, glass and other materials that meet the standard of dielectric parameters.

Further, as shown in FIG. 6 and FIG. 7, the situation where the camera mechanism of the present disclosure is connected to an accessory case with a 5G antenna is shown from the front and back of the mobile terminal, respectively. The top of the accessory cover is flush with the top of the exposed part of the camera mechanism after ejection and extends to the same length horizontally as the mobile terminal, so that there is a generous horizontal space at the top. The accessory cover is equivalent to wearing a hat for the full-screen mobile terminal to enhance the overall appearance.

According to the pop-up device for accessing the accessory case and the mobile terminal according to the embodiments of the present disclosure, the exposed part of the camera mechanism that pops up on the mobile terminal is connected to the component that can extend the information transmission function on the accessory case, thereby expanding the function of the mobile terminal. In addition, the device for pop-up access to the accessory case and the mobile terminal according to the embodiments of the present disclosure avoid process complication and appearance damage caused by implanting a signal conductive metal body.

Uncertainty in the initial development stage of 5G networks may cause some terminals to be ill-considered at the beginning of the design and need to expand the frequency band later; dense antennas and increased functions will lead to dense components; large-capacity batteries will cause space constraints; wireless headsets After replacing wired headsets, wired headsets still have practical needs; the expansion of data transmission, charging, audio and video playback and other functions of the USB (Universal Serial Bus) interface has caused a single USB port to be insufficient and need to expand the USB port. Therefore, the accessory case with 5G antenna, wired earphone port and USB port is extremely practical. This accessory case is combined with a pop-up camera, and a signal access area is added from the camera mechanism to connect the accessory case to the extended information function component, so that the mobile terminal can access the accessory case to achieve 5G network expansion and headphone port expansion And USB port expansion.

It should be pointed out that for technical details not disclosed in the terminal embodiments of the present disclosure, those skilled in the art should refer to the description of the method embodiments of the present disclosure for understanding, and will not be repeated here.

The above are only preferred embodiments of the present disclosure, and are not used to limit the protection scope of the present disclosure.
