Description

Technical Field

[0001] The present application relates to the technical field of expansion docks, and in particular to an expansion dock and an electronic device. Background Art

[0002] The desktop expansion dock products currently sold on the market are basically in the form of an adapter + a docking station body. However, since the adapter itself takes up a large space and has a long wire on the desktop; and the docking station body is also connected to the network cable and other lines, the user's desktop will be occupied by various wires, which is very messy.

[0003] At the same time, since the adapter generally converts a larger voltage into a voltage of about 20V and outputs it to the docking station body, and the docking station body needs to charge the computer (usually 20V), it also needs to power other devices connected to other interfaces, such as the USB-A port (which may be 5V) and the USB-C port (5V / 9V / 12V / 20V, etc.), and the power supply of the digital circuit part of the docking station body is basically a power supply below 5V, such as 5V / 3.3V / 1.8V / 1.2V. Therefore, after the adapter converts the higher voltage into a voltage of 20V and outputs it to the adapter body, the docking station body needs to further convert the 20V voltage to meet the power supply requirements. The adapter and the docking station body need to convert the voltage twice, and the conversion efficiency is low. In addition, since the docking station body needs to convert the voltage, it is easy to cause the docking station body to heat up, affecting the operating efficiency of the docking station body.

[0030] See also Figure 1 , Figure 1 The first embodiment of the expansion dock provided in the present application is a schematic diagram of the structure of the expansion dock 1. The expansion dock 1 provided in the first embodiment of the present application includes a main circuit board 11 and an adapter power supply 12.

[0031] Among them, the adapter power supply 12 in the expansion dock 1 is electrically connected to the main circuit board 11 to realize the integration of the adapter power supply 12 and the main circuit board 11, reduce the space occupied by the adapter being set separately, avoid the existing multiple wires occupying the desktop, causing the desktop to be messy, and improve the neatness of the desktop when the user uses the expansion dock 1, thereby improving the user experience of the expansion dock.

[0032] The main circuit board 11 includes a first circuit 111 and a second circuit 112, and the input end of the first circuit 111 and the input end of the second circuit 112 are both connected to the adapter power supply 12. The adapter power supply 12 may include two output ends, and the input end of the first circuit 111 and the input end of the second circuit 112 are respectively connected to one of the output ends of the adapter power supply 12. The first circuit 111 receives the power supply voltage output by the adapter power supply 12 and outputs a first voltage; the second circuit 112 receives the power supply voltage output by the adapter power supply 12 and outputs a second voltage; wherein the voltage value of the first voltage is greater than the voltage value of the second voltage.

[0033] For example, the adapter power supply 12 can be a 115V power supply, and the first voltage output by the adapter power supply 12 through the first circuit 111 is 20V, and the second voltage output by the adapter power supply 12 through the second circuit 112 is 5V. Therefore, the expansion dock 1 can charge the computer through the first circuit 111 and power other devices through the second circuit 112 without having to convert the voltage output by the adapter again, thereby improving the voltage conversion efficiency.

[0034] In this embodiment, the adapter power supply 12 uses the first circuit 111 and the second circuit 112 to output the first voltage and the second voltage of different voltage values ​​at one time to meet the power supply requirements of the expansion dock 1 for the devices. The expansion dock 1 does not need to convert the voltage twice, which avoids the problem in the prior art that the expansion dock body and the adapter are separately arranged, and a voltage conversion is required when the adapter outputs a voltage to the expansion dock body. In order to power electrical devices with different power supply requirements, the expansion dock body needs to perform a second conversion on the converted voltage, and the voltage is lost during the voltage conversion, which reduces the voltage conversion efficiency, thereby improving the voltage conversion efficiency of the expansion dock 1.

[0035] At the same time, the first circuit 111 and the second circuit 112 are used to convert the power supply voltage during the power supply voltage transmission process, which breaks through the limitation of the prior art that the expansion dock body and the adapter are connected by a wire (one circuit), and the voltage output by the adapter cannot be converted to obtain a different voltage value, and the expansion dock body needs to perform a secondary voltage conversion. The main circuit board 11 does not need to convert the voltage, which improves the efficiency of power supply to electrical devices and the conversion efficiency of the power supply voltage of the expansion dock 1. At the same time, there is no need to set a module for voltage conversion on the main circuit board 11, which further reduces the volume of the main circuit board 11 and the volume of the expansion dock 1.

[0036] In one embodiment, the adapter power supply 12 may also be disposed on the main circuit board 11 to further reduce the size of the docking station 1 and improve the neatness of the user's desktop when using the docking station 1 .

[0037] Alternatively, if Figure 1 As shown, the main circuit board 11 includes a first interface 113 and a second interface 114 , the output end of the first circuit 111 is connected to the first interface 113 , and the output end of the second circuit 112 is connected to the second interface 114 .

[0038] The adapter power supply 12 is electrically connected to the first electrical device through the first circuit 111 and the first interface 113, and the adapter power supply 12 is electrically connected to the first electrical device through the second circuit 112 and the second interface 114. Therefore, the adapter power supply 12 can supply power to the first electrical device through the first circuit 111 and the first interface 113; and / or the adapter power supply 12 can supply power to the second electrical device through the second circuit 112 and the second interface 114.

[0039] Specifically, the first electrical device may be a large electrical device, and the second electrical device may be a small electrical device. The large electrical device is connected to the first interface 113, and the adapter power supply 12 may output a first voltage to the large electrical device through the first circuit 111 and the first interface 113; the small electrical device is connected to the second interface 114, and the adapter power supply 12 may output a second voltage to the small electrical device through the second circuit 112 and the second interface 114 to supply power for the operation of the electrical device. The adapter power supply 12 may provide a suitable voltage to the electrical device by connecting the electrical device to the first interface 113 or the second interface 114, so as to avoid the adapter power supply 12 outputting the first voltage to the small electrical device, causing damage to the small electrical device, or the adapter power supply 12 outputting the second voltage to the large electrical device, so that the large electrical device does not obtain enough voltage to operate, thereby improving the stability of the power supply of the adapter power supply 12, improving the practicality of the expansion dock 1, and further improving the user's experience of the expansion dock 1.

[0040] It should be understood that the “size” of the “large electrical devices” and “small electrical devices” mentioned here and below does not describe the size of the electrical devices, but rather describes the size of the voltage (or power) required for the operation of the electrical devices. The voltage required for the operation of large electrical devices is greater than the voltage required for the operation of small electrical devices.

[0041] Please continue reading Figure 2 , Figure 2 It is a structural diagram of the second embodiment of the expansion dock provided by the present application. On the basis of the expansion dock 1 provided by the first embodiment of the present application, in the expansion dock 1 provided by the second embodiment of the present application, the main circuit board 11 may include multiple first interfaces 113 and multiple second interfaces 114, the first circuit 111 has multiple output terminals, and the multiple output terminals of the first circuit 111 are respectively connected to the multiple first interfaces 113, and the second circuit 112 also has multiple output terminals, and the multiple output terminals of the second circuit 112 are respectively connected to the multiple second interfaces 114.

[0042] In other embodiments, the main circuit board 11 may also include multiple first circuits 111 and multiple second circuits 112, so that each first interface 113 is connected to the adapter power supply 12 through the corresponding first circuit 111, and each second interface 114 is connected to the adapter power supply 12 through the corresponding second circuit 112, thereby improving the efficiency of the adapter power supply 12 outputting voltage through the first circuit 111 and / or the second circuit 112.

[0043] It should be understood that the number of the first interfaces 113 and the second interfaces 114 on the main circuit board 11 of the present application includes but is not limited to two, and the number of the first interfaces 113 and the number of the second interfaces 114 may not be equal.

[0044] Further, the plurality of first interfaces 113 are disposed on one side of the main circuit board 11, and the plurality of second interfaces 114 are disposed on the other side of the main circuit board 11. In another embodiment, the plurality of first interfaces 113 and the plurality of second interfaces 114 are disposed alternately.

[0045] That is, the number of the first interfaces 113 and the number of the second interfaces 114 on the main circuit board 11, as well as the specific locations of the first interfaces 113 and the second interfaces 114, can be set according to user needs, and this application does not impose any restrictions on this.

[0046] Among them, the adapter power supply 12 outputs a first voltage to the first interface 113 through the first circuit 111 to power a first electrical device connected to the first interface 113; and / or, the adapter power supply 12 outputs a second voltage to the second interface 114 through the second circuit 112 to power a second electrical device connected to the second interface 114.

[0047] The voltage value of the power supply voltage is greater than the first voltage, and the voltage value of the power supply voltage is greater than the second voltage, that is, the first circuit 111 and the second circuit 112 are step-down circuits. The first circuit 111 and the second circuit 112 can be step-down circuits in the prior art, and the detailed structures of the first circuit 111 and the second circuit 112 are not described in detail herein.

[0048] The first interface 113 may be at least one of an HDMI interface, a Display port interface and a USB-C interface, and the second interface 114 may be at least one of an Ethernet port, a USB-A interface and a USB-C interface.

[0049] Take the example where the first interface 113 is an HDMI interface, the second interface 114 is a USB-A interface, the power supply voltage output by the adapter power supply 12 is 115V, the first voltage is 20V, and the second voltage is 5V.

[0050] The first electrical device is a large electrical device (such as a computer), which can be connected to the main circuit board 11 through the first interface 113 (HDMI interface), and the second electrical device is a small electrical device (such as a mouse, keyboard, etc.), which is connected to the main circuit board 11 through the second interface 114 (USB-A interface), and then the adapter power supply 12 converts the power supply voltage into a first voltage through the first circuit 111 to supply power to the computer connected to the first interface 113. The adapter power supply 12 can also convert the power supply voltage into a second voltage through the second circuit 112 to supply power to the small electrical device connected to the second interface 114.

[0051] In summary, the expansion dock 1 provided in this embodiment includes a first interface 113 and a second interface 114, and the first interface 113 and the second interface 114 are respectively connected to electrical devices of different specifications, and then the adapter power supply 12 on the main circuit board 11 converts the power supply voltage output by the adapter power supply 12 through the first circuit 111 and the second circuit 112, and directly converts it into a voltage corresponding to the power of the electrical device, thereby supplying power to electrical devices of different specifications. There is no need to set up an additional module on the main circuit board 11 for secondary conversion of the voltage due to the different electrical devices, thereby improving the voltage conversion efficiency and the power supply efficiency to the electrical devices.

[0052] The specific interface type settings of the first interface 113 and the second interface 114, as well as the number of specific interface types set can be set by the user, and this application does not impose any restrictions on this.

[0053] Optionally, the docking station 1 further includes a housing (not shown). The main circuit board 11 and the adapter power supply 12 are disposed in the housing. The housing can then isolate the main circuit board 11 and the adapter power supply 12 from the environment, thereby preventing dust in the environment from damaging the main circuit board 11 and the adapter power supply 12, thereby improving the safety of the main circuit board 11 and the adapter power supply 12 and improving the reliability of the docking station 1. At the same time, since the housing wraps the main circuit board 11 and the adapter power supply 12, the aesthetics of the docking station 1 will also be improved.

[0054] Please continue reading Figure 3 , Figure 3 Based on the expansion dock 1 provided in the first embodiment of the present application or the expansion dock 1 provided in the second embodiment of the present application, in the expansion dock 1 provided in the third embodiment of the present application, the main circuit board 11 also includes a main control module 115 .

[0055] The adapter power supply 12 is connected to the main control module 115 through the second circuit 112, and then the adapter power supply 12 supplies power to the main control module 115 through the second circuit 112, and the main control module 115 is used to control the adapter power supply 12 to supply power to the first interface 113 and / or the second interface 114. For example, the main control module 115 can control the adapter power supply 12 through the second circuit 112, or the main control module 115 can achieve wireless connection with the adapter power supply 12 through Bluetooth, and then control the adapter power supply 12, etc. In the case of realizing the control function of the main control module 115 on the adapter power supply 12, the present application does not limit the path for the main control module 115 to send control instructions to the adapter power supply 12.

[0056] Specifically, the adapter power supply 12 outputs a second voltage to the main control module 115 through the second circuit 112 for the main control module 115 to operate (the adapter power supply 12 outputs a small voltage to the main control module 115 to power the main control module 115. It can be understood that when the voltage required for the operation of the main control module 115 is relatively large, the adapter power supply 12 can also be connected to the main control module 115 through the first circuit 111). Then, when the first electrical device is connected to the first interface 113, the main control module 115 responds to the connection of the first interface 113, and can control the adapter power supply 12 to output a voltage to the first interface 113 through the first circuit 111 to power the first electrical device. And / or, when the second electrical device is connected to the second interface 114, the main control module 115 responds to the connection of the second interface 114, and can control the adapter power supply 12 to output a voltage to the second interface 114 through the second circuit 112 to power the second electrical device. Improve the intelligence and response efficiency of the adapter power supply 12 in supplying power to the electrical device, and improve the user experience of the docking station 1.

[0057] Furthermore, the main control module 115 can also be connected to the first interface 113 and the second interface 114 respectively, and the main control module 115 is used to receive a control signal through the second interface 114, and transmit the control signal to the first electrical device connected to the first interface 113 through the first interface 113; and / or, the main control module 115 is used to receive a control signal through the first interface 113, and transmit the control signal to the second electrical device connected to the second interface 114 through the second interface 114.

[0058] For example, a computer (large electrical device) is connected to the first interface 113, and a mouse (small electrical device) is connected to the second interface 114, so that the user can operate the content on the display interface of the computer through the mouse. The main control module 115 can receive control signals such as the movement trajectory or operation information of the mouse, and then transmit them to the computer through the first interface 113, and the computer operates according to the control signals.

[0059] Or, the computer is connected to the first interface 113, and the memory card (such as a camera memory card, etc.) is connected to the second interface 114, and then the computer can send a control signal to the memory card through the first interface 113-main control module 115-second interface 114 to read the storage content of the memory card and display it on the computer display screen. The user can also operate the storage content through the computer, and then the computer transmits the control signal containing the user's operation on the storage content to the memory card through the first interface 113-main control module 115-second interface 114 to update, add or delete the storage content of the memory card.

[0060] The control signals of the electrical devices connected to the first interface 113 and the second interface 114 are exchanged through the main control module 115, so that different electrical devices can communicate signals through the expansion dock 1, thereby improving the practicality of the expansion dock 1 and enhancing the user experience of the expansion dock 1.

[0061] Among them, when the main circuit board 11 includes two or more first interfaces 113 and second interfaces 114, the main control module 115 can be connected to the first interface 113 and the second interface 114 through a multi-way circuit, and then when signal interaction is required between the corresponding first interface 113 and the corresponding second interface 114, the main control module 115 can perform signal interaction for the corresponding first interface 113 and the corresponding second interface 114 without transmitting the control signal to the wrong interface, thereby improving the accuracy and safety of the signal transmission of the main control module 115.

[0062] In other embodiments, the main control module 115 may also be connected to the first interface 113 and the second interface 114 via Bluetooth or other wireless connection forms, which is not limited in the present application.

[0063] Please continue reading Figure 4 , Figure 4 1 is a schematic diagram of the structure of the fourth embodiment of the expansion dock provided by the present application. Based on the expansion dock 1 provided by the first embodiment of the present application, the expansion dock 1 provided by the second embodiment of the present application, and one of the expansion dock 1 provided by the third embodiment of the present application, in the expansion dock 1 provided by the fourth embodiment of the present application, the adapter power supply 12 includes a power supply module 121 and a step-down module 122, the power supply module 121 is connected to the input end of the first circuit 111 and the input end of the second circuit 112 through the step-down module 122, the step-down module 122 can step down the voltage output by the power supply module 121, wherein the step-down module 122 is used to receive the voltage output by the power supply module 121, step down to obtain the power supply voltage, and output the power supply voltage to the first circuit 111 and / or the second circuit 112.

[0064] For example, the voltage output by the power supply module 121 may be 200V, and after the step-down module 122 receives the voltage output by the power supply module 121, it steps down the voltage to obtain the power supply voltage, and the power supply voltage may be 115V. Then, the step-down module 122 may output the power supply voltage to the first circuit 111 and / or the second circuit 112. After the first circuit 111 and / or the second circuit 112 receives the power supply voltage, the power supply voltage is stepped down during the transmission process, and then the first electrical device connected to the first interface 113 and / or the second electrical device connected to the second interface 114 are supplied with the response voltage, thereby ensuring the normal operation of the first electrical device and the second electrical device.

[0065] In one embodiment, the adapter power supply 12 may include two step-down modules 122, the power supply module 121 is connected to the first circuit 111 through one step-down module 122, and is connected to the second circuit 112 through another step-down module 122, and thus the step-down module 122 connected to the second circuit 112 can perform a relatively large step-down operation on the voltage output by the power supply module 121, so that the second circuit 112 converts the supply voltage into a second voltage with a smaller voltage value, that is, the voltage value of the supply voltage obtained after the step-down module 122 connected to the first circuit 111 steps down the voltage output by the power supply module 121 is greater than the voltage value of the supply voltage obtained after the step-down module 122 connected to the second circuit 112 steps down the voltage output by the power supply module 121, thereby improving the conversion efficiency of the second circuit 112 on the supply voltage.

[0066] The voltage output by the power supply module 121 is stepped down by the step-down module 122, and the voltage output by the power supply module 121 is converted into a power supply voltage of an appropriate voltage value, and then output to the first circuit 111 and the second circuit 112, thereby reducing the burden on the first circuit 111 and the second circuit 112 to receive the voltage output by the power supply module 121, and avoiding the situation where the voltage output by the power supply module 121 is too high and damages the first circuit 111 and the second circuit 112, thereby ensuring the safety of the first circuit 111 and the second circuit 112 and improving the safety of the expansion dock 1.

[0067] At the same time, a step-down module 122 is provided in the adapter power supply 12 to step down the voltage output by the power supply module 121, allowing the power supply modules 121 with different voltage values ​​to be provided in the adapter power supply 12. The user does not need to worry about the voltage output by the power supply module 121 damaging the first circuit 111 and the second circuit 112. The step-down module 122 can step down the voltage output by the power supply module 121 to a power supply voltage of an appropriate voltage value, thereby ensuring the safety of the expansion dock 1, expanding the selection of the power supply module 121 in the adapter power supply 12, and improving the user experience of the expansion dock 1.

[0068] Please continue reading Figure 5 , Figure 5 The fifth embodiment of the docking station provided in the present application is a schematic diagram of the structure of the fifth embodiment of the docking station provided in the present application. Based on the docking station 1 provided in the first embodiment of the present application, the docking station 1 provided in the second embodiment of the present application, and one of the docking stations 1 provided in the third embodiment of the present application, in the docking station 1 provided in the fifth embodiment of the present application, the adapter power supply 12 includes a first power supply module 123 and a second power supply module 124.

[0069] The first power supply module 123 is connected to the first circuit 111, and the first circuit 111 receives the power supply voltage output by the first power supply module 123, and converts the power supply voltage to output the first voltage to the first interface 113. The second power supply module 124 is connected to the second circuit 112, and the second circuit 112 receives the power supply voltage output by the second power supply module 124, and converts the power supply voltage to output the second voltage to the second interface 114.

[0070] Specifically, the first power supply module 123 can output a power supply module with a voltage of 115V, and the second power supply module 124 can output a power supply module with a voltage lower than 115V. After the second circuit 112 receives a relatively small power supply voltage, the second circuit 112 converts the power supply voltage into a second voltage lower than the first voltage, thereby improving the conversion efficiency of the second circuit 112 for the power supply voltage.

[0071] In one embodiment, the main circuit board 11 may further include a plurality of first circuits 111 and a plurality of second circuits 112, wherein the input ends of the plurality of first circuits 111 are connected to the first power supply module 123, and the output ends of the plurality of first circuits 111 are respectively connected to the corresponding first interfaces 113; the input ends of the plurality of second circuits 112 are connected to the second power supply module 124, and the output ends of the plurality of second circuits 112 are respectively connected to the corresponding second interfaces 114. Thus, the first power supply module 123 may supply power to the corresponding first interface 113 through the corresponding first circuit 111, and the second power supply module 124 may supply power to the corresponding second interface 114 through the corresponding second circuit 112, thereby improving the efficiency of the adapter power supply 12 outputting voltage to the first interface 113 and the second interface 114, and improving the power supply efficiency of the expansion dock 1.

[0072] In another embodiment, the adapter power supply 12 may also include multiple first power supply modules 123 and multiple second power supply modules 124, each first power supply module 123 is connected to the corresponding first interface 113 through the corresponding first circuit 111, and each second power supply module 124 is connected to the corresponding second interface 114 through the corresponding second circuit 112, that is, each first power supply module 123 only supplies power to the corresponding first interface 113, and each second power supply module 124 also only supplies power to the corresponding second interface 114, thereby further improving the efficiency of the adapter power supply 12 in outputting voltage to the first interface 113 and the second interface 114, and improving the power supply efficiency of the expansion dock 1.

[0073] In other embodiments, based on the expansion dock 1 provided in the fourth embodiment, the adapter power supply 12 may further include two step-down modules 122, the first power supply module 123 is connected to the first circuit 111 through the corresponding step-down module 122, and the second power supply module 124 is connected to the second circuit 112 through the corresponding step-down module 122, and then the step-down module 122 steps down the voltage output by the connected first power supply module 123 and / or the second power supply module 124 to obtain a power supply voltage of a suitable voltage to be output to the first circuit 111 and the second circuit 112. It can be understood that in this embodiment, if the adapter power supply 12 includes multiple first power supply modules 123 and multiple second power supply modules 124, the adapter power supply 12 may include a corresponding number of step-down modules 122 to step down the voltage output by the first power supply module 123 and the second power supply module 124, so as to improve the voltage conversion efficiency of the expansion dock 1.

[0074] Optionally, see Figure 3 The expansion dock 1 provided in the embodiment of the present application also includes a charging interface 116, which is electrically connected to the adapter power supply 12, and then an external power source can be electrically connected to the adapter power supply 12 through the charging interface 116 to charge the adapter power supply 12.

[0075] In summary, in the expansion dock 1 provided in the embodiment of the present application, the adapter power supply 12 is electrically connected to the main circuit board 11, thereby realizing the integration of the adapter power supply 12 and the main circuit board 11, reducing the space occupied by the adapter being separately set up, avoiding the existing multiple wires occupying the desktop, causing the desktop to become cluttered, and improving the neatness of the desktop when the user uses the expansion dock 1, thereby improving the user experience of using the expansion dock 1.

[0076] At the same time, the adapter power supply 12 is connected to the first interface 113 through the first circuit 111, and outputs the first voltage through the first interface 113; it is connected to the second interface 114 through the second circuit 112, and outputs the second voltage through the second interface 114. The adapter power supply 12 converts the power supply voltage output by the adapter power supply 12 through the first circuit 111 and the second circuit 112, and directly converts it into the voltage required by the corresponding electrical device, thereby supplying power to electrical devices of different specifications, without the need to set up additional modules on the main circuit board 11 for secondary conversion of the voltage due to different electrical devices, thereby improving the conversion efficiency of the voltage of the expansion dock 1.

[0077] The present application also provides an electronic device (not shown), which includes a docking station 1, a first electrical device and a second electrical device, wherein the first electrical device and the second electrical device are connected to the docking station 1, and the docking station 1 supplies power to the first electrical device and the second electrical device.

The adapter power supply 12 in the expansion dock 1 supplies power to the first electrical device via the first circuit 111, and supplies power to the second electrical device via the second circuit 112.
