It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] This application provides a transmission system. Figure 1The transmission system 1000 may include a transmission device 100 and an electronic device 500. When in working state, the transmission device 100 is magnetically connected to the electronic device 500, and the transmission device 100 may transmit data and / or electrical energy to the electronic device 500. The electronic device 500 may be a portable device such as a mobile phone, a tablet computer, a laptop computer, and a wearable device. The embodiment of the present application is described by taking the electronic device 500 as a mobile phone as an example. Compared with the plug-in interface, the magnetic connection has a low contactless magnetic connection docking accuracy requirement, and the contact between the transmission device 100 and the electronic device 500 will not be damaged due to inaccurate docking, which can improve the reliability of transmission.

[0026] This application provides a transmission device. Figure 2 The transmission device 100 may include a transmission component 10, a transmission line 20 and a connector 30. The transmission component 10 and the connector 30 are respectively connected to opposite ends of the transmission line 20, and the connector 30 may be connected to a power source or an electronic product.

[0027] The transmission component 10 has a first end 19 for connecting to an electronic device 500, such as Figure 2 The first end 19 may be an end of the transmission component 10 that is connected to the transmission line 20 to prevent the transmission line 20 from blocking the connection between the transmission component 10 and the electronic device 500. Optionally, the first end 19 is an end of the transmission component 10 that is connected away from the transmission line 20.

[0028] See also Figure 3-Figure 5 , the transmission component 10 may include a first circuit board 11 and a first magnetic component 12. The first magnetic component 12 may be a neodymium iron boron magnet, such as an N52SH magnet. The transmission component 10 can be magnetically connected to the electronic device 500 through the first magnetic component 12. The first circuit board 11 is connected to the transmission line 20, and the first circuit board 11 is used for power or data transmission control, so that the transmission component 10 and the electronic device 500 can automatically negotiate when they are magnetically connected, so that the transmission device 100 can transmit data or power to the electronic device 500. The first magnetic component 12 is arranged close to the first end 19, so that when the transmission component 10 and the electronic device 500 are magnetically connected, the first magnetic component 12 is closer to the electronic device 500, the magnetic attraction between the two is stronger, and the connection between the transmission component 10 and the electronic device 500 is not easy to fall off.

[0029] A first end-fire antenna 111 is integrated on the first circuit board 11, and is used for wireless data transmission with the electronic device 500. Specifically, a second end-fire antenna may be correspondingly provided in the electronic device 500, and the second end-fire antenna is coupled to the first end-fire antenna 111 to wirelessly transmit data to the electronic device 500. Since the data transmission method is wireless transmission, compared with wired contact transmission, the plug-in wear and tear between metal conductors that may easily occur and cause interface damage can be avoided, and the reliability of data transmission can be improved. It should be noted that the data transmission of the transmission component 10 is full-duplex, that is, data can be received while sending data, and the two can be carried out simultaneously. The first end-fire antenna 111 is arranged close to the first end 19 to shorten the distance between the first end-fire antenna 111 and the second end-fire antenna, thereby improving the efficiency of data transmission.

[0030] The transmission device 100 provided in the present application is provided with a first end-fire antenna 111 and a first magnetic component 12. The first end-fire antenna 111 is used for wireless data transmission with the electronic device 500. The transmission component 10 can be magnetically connected to the electronic device 500 through the first magnetic component 12. Compared with the plug-in interface, the contactless magnetic connection has low docking accuracy requirements. The contact between the transmission component 10 and the electronic device 500 will not be damaged due to inaccurate docking, which can improve the transmission reliability of the transmission device 100.

[0031] Please continue reading Figure 3-Figure 5 , the transmission component 10 may also include a first coil 13, and the first coil 13 may wirelessly transmit power to the electronic device 500. Specifically, the electronic device 500 may be provided with a second coil, and the second coil may be coupled with the first coil 13, so as to wirelessly transmit power to the electronic device 500. The first coil 13 is arranged close to the first end 19, which can reduce the distance between the first coil 13 and the electronic device 500, thereby improving the power transmission efficiency. By arranging the first coil 13 to wirelessly transmit power to the electronic device 500, the transmission component 10 can transmit both data and power. Since the transmission component 10 and the electronic device 500 are connected magnetically without contact points, the docking accuracy requirement is low, and the contact between the transmission component 10 and the electronic device 500 will not be damaged due to inaccurate docking, which can improve the transmission reliability of the transmission device 100.

[0032] When the electronic device 500 needs to perform data transmission, the connector 30 can be connected to other electronic products. When the electronic device 500 needs to be charged, the connector 30 can be connected to a power source or to other electronic products, that is, the transmission device 100 can be used for power transmission between electronic devices. The transmission line 20 can support charging and data transmission, and the transmission line 20 can be a Type-C data line.

[0033] In one embodiment, if Figure 4 , Figure 5As shown, the first end-fire antenna 111 protrudes from the first circuit board 11 and extends in the direction of the first end 19. Two first end-fire antennas 111 are provided, and the two first end-fire antennas 111 are distributed on opposite sides of the first circuit board 11 near the first end 19. The two first end-fire antennas 111 can be symmetrically distributed, so that both the front and back sides of the transmission component 10 can be connected to the electronic device 500 for easy use.

[0034] The first end-fire antenna 111 may be a dual-polarized antenna, including a horizontally polarized dipole antenna and a vertically polarized monopole antenna. The horizontally polarized dipole antenna adopts a trapezoidal floor structure to increase the antenna impedance bandwidth; the vertically polarized monopole antenna adopts a quasi-Yagi-Uda antenna form and introduces a reflector arm oscillator to improve the end-fire gain.

[0035] The RF chip is connected to two first end-fire antennas 111 through transmission lines, respectively, to excite a 1 / 2 wavelength dipole mode to generate horizontal polarization radiation, and to excite a 1 / 4 wavelength monopole mode to generate vertical polarization radiation. Since the dual-polarized antennas are orthogonally polarized and isolated by the floor, the isolation between the dual-polarized antennas is good, greater than 25dB; the distance between the antenna pairs exceeds 2 wavelengths, and the isolation is greater than 40dB.

[0036] Please continue reading Figure 3-Figure 5 , the transmission component 10 may also include a first magnetic member bracket 14, a first coil rod 15, a transmission end housing 16, a positioning bracket 17 and a bottom cover 18. The first circuit board 11, the first magnetic member 12, the first coil 13, the first magnetic member bracket 14 and the first coil rod 15 are installed in the transmission end housing 16. The positioning bracket 17 and the bottom cover 18 are installed at one end of the transmission end housing 16 close to the connection of the connector 30, and the positioning bracket 17 is engaged between the inner wall of the transmission end housing 16 and the first circuit board 11 to prevent the first circuit board 11 from shifting, thereby improving the reliability of the transmission component 10. The bottom cover 18 is covered on the transmission end housing 16. The bottom cover 18 may include two symmetrical cover plates, and an opening is provided in the middle of the cover plate so that the transmission line 20 can pass through the opening, thereby facilitating the installation of the bottom cover 18. When assembling the bottom cover 18, the two cover plates are respectively assembled into the transmission end housing 16 from both sides of the transmission line 20. The bottom cover 18 and the transmission end housing 16 form a relatively closed space, thereby providing protection for components installed inside the closed space.

[0037] In one embodiment, if Figure 4 , Figure 5As described above, the end surface of the transmission end housing 16 close to the first end 19 is provided with a fitting 161, and the fitting 161 protrudes from the transmission end housing 16. Accordingly, a fitting hole can be correspondingly provided on the electronic device 500, and when the electronic device 500 is connected to the transmission component 10, the fitting 161 can be inserted into the fitting hole, thereby facilitating the connection and alignment between the electronic device 500 and the transmission component 10.

[0038] The first magnetic member bracket 14 is disposed on the first end-fire antenna 111. Figure 4 , Figure 5 The first magnetic member bracket 14 can be used to install the first magnetic member 12. The first magnetic member 12 can be attached to the first magnetic member bracket 14 with double-sided tape to prevent the first magnetic member 12 from shifting.

[0039] See also Figure 3-Figure 5 , the first coil 13 is wound around the outer periphery of the first coil rod 15, and the first coil rod 15 is installed on the first magnetic member bracket 14. The first coil rod 15 can be attached to the first magnetic member bracket 14 with double-sided tape. The first coil rod 15 is made of metal, and the first coil rod 15 can be in a rod shape. The first coil 13 is wound in the middle area of ​​the first coil rod 15. The first coil rod 15 provides a support frame for the first coil 13, facilitates the installation of the first coil 13, and can increase the self-inductance coefficient of the first coil 13, thereby improving the charging efficiency.

[0040] In one embodiment, if Figure 5 As shown, the end face of the first end-fire antenna 111 is flush with the outer end face of the transmission end housing 16. That is, an opening is provided on the transmission end housing 16, so that the end face of the first end-fire antenna 111 can be exposed to the transmission end housing 16, reducing the shielding of the first end-fire antenna 111 by the transmission end housing 16, and improving the data transmission efficiency. The side of the first coil rod 15 close to the first end 19 partially protrudes from the transmission end housing 16, which can reduce the distance between the first coil rod 15 and the electronic device 500, thereby improving the charging efficiency.

[0041] The first magnetic member 12 and the first coil 13 are both mounted on the first magnetic member bracket 14. The first magnetic member 12 affects the magnetic field generated by the first coil 13. In one embodiment, Figure 4-Figure 6 As shown, the first magnetic member bracket 14 is provided with a first partition 141 extending in the direction of the first end 19, two first partitions 141 are arranged between the two first end-fire antennas 111, one side of the first partition 141 is attached to the first end-fire antenna 111, and the first coil rod 15 is installed between the two first partitions 141. Through the above arrangement, the first partition 141 separates the first magnetic member 12 from the first coil 13, and the first partition 141 can shield the mutual influence between the magnetic fields of the two.

[0042] Optionally, the first magnetic member 12 may be U-shaped, such as Figure 3 , Figure 4 As shown, the opening of the first magnetic member 12 is engaged with the first end-fire antenna 111, and the first magnetic member 12 is in contact with the first partition 141. The first magnetic member 12 is set to be U-shaped. On the one hand, it is convenient to use the U-shaped opening for engagement and installation; on the other hand, the first end-fire antenna 111 is accommodated in the opening of the first magnetic member 12, which reduces space occupation, improves the space utilization rate of the transmission component 10, and can reduce the volume of the transmission component 10.

[0043] The connector 30 can be configured in the same manner as the transmission component 10, that is, both ends of the transmission device 100 can be magnetically connected to a power source or an electronic product. The configuration of the connector 30 can also be different from that of the transmission component 10, such as Figure 7 As shown, in one embodiment, the connector 30 includes a plug circuit board 31, a plug end shell 32 and a plug back cover 33. One end of the plug circuit board 31 is connected to the transmission line 20, and the plug circuit board 31 is provided with a plug male socket 311, which can be connected to a power source or an electronic product. The plug circuit board 31 is accommodated in the plug end shell 32, and the plug back cover 33 is provided at one end away from the plug male socket 311, so that the plug circuit board 31 is enclosed in the plug end shell 32 to prevent external moisture or dust from invading the plug end shell 32.

[0044] The present application provides an electronic device. Figure 8 , Fig. 9 , the electronic device 500 may include a receiving component 50 and a shell 60. The receiving component 50 is installed at one end of the shell 60, and the outer surface of the receiving component 50 may be flush with the outer surface of the shell 60. The shell 60 may include a back cover 61 and a middle frame 62, and the back cover 61 covers the middle frame 62. The middle frame 62 is provided with a mounting frame 621, a device sub-board 622 and a flexible connecting plate 623. The mounting frame 621 is used to install the receiving component 50, and the flexible connecting plate 623 is buckled between the device sub-board 622 and the receiving component 50. The receiving component 50 can cooperate with an external transmission device to transmit data to the electronic device 500. The external transmission device may be the transmission device 100 as described above, and the embodiment of the present application is described by taking the external transmission device as the transmission device 100 as an example.

[0045] See also Figure 10-12, the receiving component 50 has a second end 59 for connecting to an external transmission device. The receiving component 50 may include a second circuit board 51 and a second magnetic member 52. The second magnetic member 52 may be a neodymium iron boron magnet, such as an N52SH magnet. The second magnetic member 52 is arranged near the second end 59 and can be aligned with the external transmission device. The second magnetic member 52 is arranged near the second end 59, so that when the receiving component 50 is magnetically connected to the external transmission device, the second magnetic member 52 is closer to the first magnetic member 12, the magnetic attraction between the two is stronger, and the connection between the receiving component 50 and the external transmission device is not easy to fall off. Specifically, when the external transmission device is the transmission device 100, the second magnetic member 52 can be arranged corresponding to the first magnetic member 12, that is, the magnetic pole of the second magnetic member 52 is opposite to the magnetic pole of the first magnetic member 12, so that when the two are close, the second magnetic member 52 can be magnetically connected to the first magnetic member 12, so that the receiving component 50 is magnetically connected to the transmission component 10.

[0046] A second end-fire antenna 511 is integrated on the second circuit board 51, and is used for wireless data transmission with an external transmission device. Since the data transmission method is wireless transmission, compared with wired contact transmission, it avoids the plug-in wear and tear that is easy to occur between metal conductors, resulting in interface damage, and can improve the reliability of data transmission. Specifically, when the external transmission device is the transmission device 100, the second end-fire antenna 511 can be set corresponding to the first end-fire antenna 111. It should be noted that the data transmission of the receiving component 50 is full-duplex, that is, data can be received while sending data, and the two can be performed synchronously. The second end-fire antenna 511 is arranged close to the second end 59, so that the second end-fire antenna 511 and the first end-fire antenna 111 extend toward each other, which can shorten the distance between the two, thereby improving the efficiency of data transmission.

[0047] The electronic device 500 provided in the present application has a second magnetic component 52 that can be aligned and attracted to an external transmission device. Compared with a plug-in interface, the contactless magnetic connection has low docking accuracy requirements, and the contact point between the receiving component 50 and the external transmission device will not be damaged due to inaccurate docking, thereby improving the transmission reliability of the electronic device 500.

[0048] The electronic device 500 also includes a second coil 53, which can cooperate with an external transmission device to wirelessly transmit power to the electronic device 500. Specifically, when the external transmission device is the transmission device 100, the second coil 53 can be arranged corresponding to the first coil 13, and the first coil 13 is coupled to the second coil 53 to wirelessly transmit power to the electronic device 500. The second coil 53 is arranged close to the second end 59, which can reduce the distance between the second coil 53 and the first coil 13, thereby improving the power transmission efficiency. By setting the second coil 53, both data and power can be transmitted between the receiving component 50 and the external transmission device. Since the receiving component 50 and the external transmission device are contactless magnetic connections, the docking accuracy requirements are low, and the contact between the receiving component 50 and the external transmission device will not be damaged due to inaccurate docking, which can improve the transmission reliability of the electronic device 500.

[0049] In one embodiment, if Fig.11 , Fig.12 As shown, the second end-fire antenna 511 protrudes from the second circuit board 51 and extends toward the second end 59 . Two second end-fire antennas 511 are provided, and the two second end-fire antennas 511 are distributed on opposite sides of the second circuit board 51 near the second end 59 .

[0050] The second end-fire antenna 511 may be a dual-polarized antenna, including a horizontally polarized dipole antenna and a vertically polarized monopole antenna, so as to improve the end-fire gain.

[0051] Please continue to see 10- Fig.12 The receiving assembly 50 may further include a second magnetic member bracket 54, a second coil rod 55, and a bottom bracket 56. The second magnetic member bracket 54 is disposed on the second end-fire antenna 511. The second magnetic member bracket 54 may be used for mounting the second magnetic member 52. The second magnetic member 52 may be attached to the second magnetic member bracket 54 with double-sided tape to prevent the second magnetic member 52 from shifting.

[0052] The second coil 53 is wound around the outer circumference of the second coil rod 55, and the second coil rod 55 is installed on the second magnetic member bracket 54. The second coil rod 55 can be attached to the second magnetic member bracket 54 with double-sided tape. The second coil rod 55 is made of metal, and the second coil rod 55 can be in a rod shape. The second coil 53 is wound in the middle area of ​​the second coil rod 55. The second coil rod 55 provides a support frame for the second coil 53, facilitates the installation of the second coil 53, and can increase the self-inductance coefficient of the second coil 53, thereby improving the charging efficiency.

[0053] The bottom bracket 56 is installed near the second end 59. The bottom bracket 56 is provided with a positioning hole 561. Fig.12 , Fig.13As shown, the second magnetic member bracket 54 is provided with a positioning column 541, and the positioning column 541 is accommodated and installed in the positioning hole 561. By providing the positioning column 541 and the positioning hole 561, it is convenient to accurately install the second magnetic member bracket 54 on the bottom bracket 56, which can improve the assembly efficiency.

[0054] The bottom bracket 56 is provided with a second partition plate 562 extending in the direction of the second magnetic member 52. Fig.12 , Fig.13 As shown, two second partitions 562 are spaced apart between the two second end-fire antennas 511, one side of the second partition 562 is attached to the second end-fire antenna 511, and the second coil rod 55 is installed between the two second partitions 562. The second partition 562 separates the second magnetic member 52 from the second coil 53, and the second partition 562 can shield the mutual influence between the magnetic fields of the two.

[0055] The end surface of the bottom bracket 56 close to the second end 59 is provided with a fitting hole 563. Fig.11 , Fig.12 As shown, when the receiving component 50 is connected to the external transmission device, the fitting member 161 provided on the external transmission device can be inserted into the fitting hole 563, thereby facilitating the connection and alignment between the receiving component 50 and the external transmission device.

[0056] Optionally, the second magnetic member 52 may be U-shaped, such as Fig.11 As shown, the opening of the second magnetic member 52 is engaged with the second end-fire antenna 511, and the second magnetic member 52 is in contact with the second partition plate 562. The second magnetic member 52 is set to be U-shaped. On the one hand, it is convenient to use the U-shaped opening for engagement and installation; on the other hand, the second end-fire antenna 511 is accommodated in the opening of the second magnetic member 52, which reduces space occupation, improves space utilization of the electronic device 500, and is conducive to the arrangement of other components.

[0057] In one embodiment, if Fig.12 As shown, one side of the second coil rod 55 close to the second end 59 partially protrudes from the bottom bracket 56, which can reduce the distance between the second coil rod 55 and the first coil rod 15, thereby improving the charging efficiency.
