Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B.

[0056] In order to provide a convenient and reliable charging method for a mobile terminal, this embodiment discloses a mobile terminal charging stand. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an explosion of the back of a mobile terminal charging stand disclosed in this embodiment. Figure 2 The figure is a front exploded schematic diagram of a mobile terminal charging stand disclosed in this embodiment. The mobile terminal charging stand disclosed in this embodiment includes: a support stand 1, a power converter 2 and a power external connection terminal 3, wherein:

[0057] Please refer to Figure 2 and Figure 3 , Figure 3 The front view of the three-dimensional structure of a mobile terminal charging stand disclosed in this embodiment is shown in FIG. The front of the support stand 1 is used to abut against the back of the mobile terminal to support the mobile terminal. The front of the support stand 1 is provided with an electrical interface 10. The electrical interface 10 is electrically connected to the power interface of the mobile terminal when the mobile terminal abuts against the front of the support stand 1. In this embodiment, the mobile terminal may be a tablet computer or the like.

[0058] In a specific embodiment, the support base 1 can be connected to the mobile terminal by a snap-on method. In this embodiment, a snap-on portion can be provided at the front side of the support base 1. The mobile terminal can also be supported by a vertical limit method. In this embodiment, a raised support portion can be provided at the front bottom of the support base 1. The mobile terminal can also be adsorbed by magnetic attraction. In this embodiment, matching magnetic attraction parts can be provided on the mobile terminal and the support base 1. In this embodiment, it is preferred to support the mobile terminal by magnetic attraction, so that when the mobile terminal is placed on the support base 1, the overall appearance is more concise and beautiful, thereby improving the visual effect of the user.

[0059] In the specific implementation process, the electrical interface 10 can be a wired interface or a wireless interface. When the electrical interface 10 is a wireless interface, the wireless interface (that is, the wireless charging coil) can be relatively centrally arranged in the support base 1, preferably matching the position of the charging coil of the mobile terminal. When the electrical interface 10 is a wired interface, the wired interface should be as close as possible to the power interface of the mobile terminal. In some embodiments, the wired interface should correspond to the position of the power interface of the mobile terminal. When the mobile terminal abuts against the front of the support base 1, the electrical interface 10 is in direct contact with the power interface of the mobile terminal to achieve electrical connection, thereby simplifying the cumbersome operation of the user. In some embodiments, the electrical interface 10 (wired interface) can also be integrated with the power converter 2, for example, the electrical interface 10 (wired interface) is welded on the PCB of the power converter 2.

[0060] Please refer to Figure 2 and Figure 4 , Figure 4 This is a schematic diagram of a rear-view stereoscopic structure of a mobile terminal charging stand disclosed in this embodiment. The power converter 2 is arranged on the back of the support base 1, and the projection of the power converter 2 on the front of the support base 1 is completely located in the plane where the front of the support base 1 is located. In this embodiment, the power converter 2 is arranged on the back of the support base 1. Please refer to Figure 4 , indicating the projection direction. When the power converter 2 is projected in this projection direction, its projection is completely located in the plane where the front of the support base 1 is located. With this arrangement, when the user uses the mobile terminal, the power converter 2 can be shielded by the support base 1, thereby avoiding visual interference caused by the power converter 2 to the user.

[0061] Please refer to Figure 1 and Figure 5 , Figure 5 This is a rear stereoscopic schematic diagram of a power converter disclosed in this embodiment. In this embodiment, the external power terminal 3 is arranged on the side of the power converter 2 away from the support base 1. Specifically, the external power terminal 3 can be a mainstream USB, mini USB, Type-C and other interfaces, or it can be a lighting interface, as long as the external power terminal 3 can be connected to an external power source.

[0062] In this embodiment, the power converter 2 is used to convert the external power received by the power external connection terminal 3 into a charging power matched with the mobile terminal and output it to the electrical interface 10. In the specific implementation process, a power conversion circuit can be set on the power converter 2. The power conversion circuit can be an existing conversion circuit. As long as the power conversion circuit can realize the conversion of the received power into a charging power matched with the mobile terminal, a buck, a booster, etc. can be configured in the power conversion circuit according to the needs of the actual scene, and a filter module, etc. can also be configured. These circuits and components can be set on a PCB, or on multiple small PCBs, and connected to a relatively larger PCB.

[0063] Please refer to Figure 1 and Figure 2 In a specific embodiment, the mobile terminal charging base further includes a cover body 4, and the support base 1 includes a back plate 11, wherein:

[0064] The back plate 11 is the back of the support seat 1, and the connection area between the cover body 4 and the back plate 11 is provided with a receiving groove 111, and the power converter 2 is arranged in the receiving groove 111. The back plate 11 can be made of plastic material or metal material. Specifically, the size of the receiving groove 111 is adapted to the outer contour of the power converter 2, so that the power converter 2 body can be placed in the receiving groove 111 as a whole. Of course, the power external connection terminal 3 should be able to extend out of the receiving groove 111. In one embodiment, the receiving groove 111 can be opened on the back plate 11, and the power converter 2 is covered by the cover body 4 after being arranged in the receiving groove 111; in another embodiment, the receiving groove 111 can also be opened on the cover body 4, and the power converter 2 is fixed to the back plate 11 together with the cover body 4 after being arranged in the receiving groove 111; in the third embodiment, the receiving groove 111 can also be formed by the cover body 4 and the back plate 11, and the power converter 2 can be fixed on the back plate 11 or on the inner cavity of the cover body 4. In a specific embodiment, the body of the power converter 2 may be a PCB, and the entire PCB is received in the receiving groove 111. This arrangement makes the back of the back plate 11 overall flatter and more compact, and can better protect the power converter 2.

[0065] In an optional embodiment, the mobile terminal charging seat further includes a cover plate 12 , the size of the cover plate 12 is adapted to the back plate 11 , and the cover plate 12 covers the back plate 11 as the front side of the support seat 1 .

[0066] To reduce hardware costs and facilitate user use, please refer to Figure 6 , Figure 6This is a front perspective schematic diagram of a power converter disclosed in this embodiment. In an optional embodiment, the electrical interface 10 is an electrical pin, and the electrical pin includes a charging pin 10a; the cover plate 12 is provided with a through hole adapted to the electrical pin; the electrical pin passes through the through hole and at least partially protrudes from the side of the cover plate 12 abutting against the mobile terminal. In this embodiment, the electrical interface 10 is an electrical pin, and passes through the through hole on the cover plate 12, and at least partially protrudes from the side of the cover plate 12 abutting against the mobile terminal, so that the electrical pin can contact the back of the mobile terminal, thereby being electrically connected to the mobile terminal. In the specific implementation process, a power interface compatible with the electrical pin can be set on the back of the mobile terminal. When the mobile terminal abuts against the front of the support base 1, the electrical pin directly contacts the compatible power interface to achieve electrical connection. As a typical application scenario of this embodiment, when the mobile terminal is an "iPad", an electrical contact (i.e., a power interface) is set on the back of the "iPad". When the "iPad" abuts against the cover plate 12, the electrical contact can directly contact the electrical pin to achieve electrical connection. In the case where there is no power interface on the back of the mobile terminal, the power interface can also be led to the back of the mobile terminal through a flat cable to match the electrical pin. In this way, when the mobile terminal abuts against the front of the support base 1, the electrical pin can also directly contact the interface on the flat cable, so that the wire pin is electrically connected to the power interface of the mobile terminal through the flat cable interface and the flat cable. With such arrangement, when the user places the mobile terminal against the front of the support base 1, the electrical connection between the electrical pin and the mobile terminal can be achieved, which is convenient for the user; and because the pin is used, the hardware cost can be saved compared to a dedicated electrical connector.

[0067] In the specific implementation process, the axial direction of the electrical pin can be insulated by the insulating sleeve. In the preferred embodiment, the cover plate 12 is an insulator, and the electrical pin does not need to be covered with the insulating sleeve in the axial direction. This configuration, on the one hand, reduces the process of covering the insulating sleeve, thereby saving processing costs; on the other hand, the cover plate can also achieve insulation between the electrical pin and the outside world, ensuring the reliability of the work.

[0068] In a preferred embodiment, the electrical pin is perpendicular to the side of the cover plate 12 that abuts the mobile terminal, and the power external connection terminal 3 provided on the power converter 2 is perpendicular to the side of the cover plate 12 that abuts the mobile terminal. In this embodiment, by vertically arranging the power external connection terminal 3 and the cover plate 12, it can be ensured that the charging line is connected to the back of the back plate 11 perpendicularly to the cover plate, so that the charging line can be better shielded, and because the charging line is arranged vertically, when the support base 1 rotates, it is not easy to entangle the charging line, thereby improving the user experience. By vertically arranging the electrical pin and the cover plate 12, the wire pin is easy to dock with the power interface of the mobile terminal, ensuring the reliability of the docking connection.

[0069] In an optional embodiment, the back plate 11 is made of metal, and the support base 1 supports the mobile terminal by magnetic attraction of the back plate 11. Specifically, this embodiment is applicable to the case where a magnetic attraction component is provided on the back of the mobile terminal.

[0070] In order to enrich the usage scenarios of the mobile terminal, in an optional embodiment, please refer to Figure 6 , the electrical pins also include: a communication pin 10b, which is connected to the communication interface of the mobile terminal when the mobile terminal is abutted against the front of the support base 1; the power external terminal 3 is a standard communication interface, and the communication pin 10b and the charging pin 10a are electrically connected to the communication terminal and the power terminal in the standard communication interface respectively through the power converter 2. Specifically, the mobile terminal uses the "0" and "1" digital communication method to exchange data through the communication pin 10b, and the power converter 2 can also be provided with a protocol conversion module to convert digital communication into a communication signal of the standard communication interface, which can communicate with third-party devices (such as keyboards, mice, etc.).

[0071] In order to reduce hardware costs and make the structure more compact, in an optional embodiment, please refer to Figure 6 The electrical pins also include: a ground pin 10c, the communication pin 10b and the charging pin 10a use the ground pin 10c for grounding, so that the mobile terminal and the power converter 2 share the same ground. It should be noted that, Figure 6 The positional relationship among the charging pin 10a, the communication pin 10b and the grounding pin 10c is only exemplarily illustrated. In the specific implementation process, the positional relationship among the charging pin 10a, the communication pin 10b and the grounding pin 10c can be adjusted according to actual needs, as long as the three pins can achieve their respective corresponding electrical connections.

[0072] To facilitate fixing the power converter 2, please refer to Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the back structure of a back panel disclosed in this embodiment, Figure 8 for Figure 7 In the partial enlarged view of A in the middle, in an optional embodiment, a plurality of lugs 112 extending toward the receiving slot 111 are provided on the back panel 11, and one or more lugs 112 are provided with lug screw holes 113; the power converter 2 is fixed in the receiving slot 111 through the lug screw holes 113.

[0073] To facilitate quick positioning and limit fixation, in the optional embodiment, please refer to Figure 8, the lug 112 is sunken by a preset distance relative to the side of the back plate 11 facing away from the mobile terminal to form a support table, the contour of the receiving groove 111 is adapted to the outer contour of the power converter 2, and the lug screw hole 113 is aligned with the screw hole provided on the power converter 2 when the power converter 2 is placed on the lug 112. In this embodiment, during the installation of the power converter 2, the user only needs to place the power converter 2 on the support table to align the lug screw hole 113 with the screw hole on the power converter 2, and at this time, only the screws need to be tightened to complete the fixation. It can be seen that this embodiment can facilitate the rapid positioning and placement of the power converter 2, and can quickly limit and fix it, thereby improving the installation efficiency.

[0074] Please refer to Figure 1 , Figure 2 and Figure 4 In an optional embodiment, the cover body 4 is provided with a through slot 40 adapted to the outer contour of the power external connection terminal 3; the cover body 4 covers the receiving slot 111. In this embodiment, by providing the cover body 4, the power converter 2 can be effectively protected, especially when the body of the power converter 2 is a PCB without an additional housing (saving parts), the cover body 4 can be used for dust protection.

In this embodiment, through the cooperation of the base 5 and the vertical rod 6, the height of the support seat 1 can be raised, and the vertical rod 6 can be rotated relative to the base 5, and the support seat 1 can be rotated relative to the vertical rod 6, so that the user can adjust the posture of the support seat 1 easily, and because the charging cable is on the back of the support seat 1, the charging cable can always be blocked by the support seat 1 during the user's adjustment of the posture of the support seat 1, so as not to affect the user's visual effect.

[0076] In an alternative embodiment, please refer to Fig. 9 , a protrusion 63 is provided on the vertical rod 6, and the protrusion 63 is rotatably connected to the second end 62 relative to the axial direction of the vertical rod 6; the back of the support seat 1 is rotatably connected to the protrusion 63, and the support seat 1 is rotatable relative to the axial direction of the protrusion 63.

In the specific implementation process, the structure after the support seat 1, the base 5 and the vertical rod 6 are assembled is as follows Fig.10 As shown, Fig.10 This is a schematic diagram of an assembly structure of a support seat, a base and a vertical pole disclosed in this embodiment.

[0077] In order to enable various mobile terminals to adapt to the mobile terminal charging seat disclosed in the above embodiment, this embodiment also discloses a mobile terminal electrical connection system, including: the mobile terminal charging seat disclosed in the above embodiment and a power adapter, wherein the power adapter is arranged on the back of the mobile terminal to provide power for the mobile terminal; when the mobile terminal abuts against the front of the support seat 1, the power adapter is electrically connected to the electrical interface 10 on the support seat 1. Specifically, the power adapter can disconnect the electrical connection with the power interface of the mobile terminal; in terms of space, the power adapter is arranged on the back of the mobile terminal, so that the back of the mobile terminal extends the power interface, whereby, when the mobile terminal abuts against the front of the support seat 1, the power adapter on the back of the mobile terminal will contact the electrical interface 10 on the support seat 1, so that the power adapter is electrically connected to the electrical interface 10, thereby realizing the electrical connection between the power adapter and the electrical interface 10 of the mobile terminal.

[0078] In an optional embodiment, the power adapter is connected to the power interface of the mobile terminal via an FPC. In this embodiment, the power interface on the side of the mobile terminal can be transferred to the back of the mobile terminal by utilizing the flexible, bendable and sufficiently thin characteristics of the FPC.
