[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Example 1

[0047] like Figures 1 to 6 A specific implementation of a modular all-in-one machine is shown, comprising a column 6, a screen mainboard 2, a PC board connector, a PC board 3 and a display part 1.

[0048] The column 6 is used for supporting. A notch is provided on the column 6, and the notch is a rectangular hole, and other shapes of notches can also be adopted, and its specific shape is not limited here.

[0049] The screen mainboard 2 is fixedly arranged inside the column 6, and can be specifically fixed on the column 6 by screws. The screen mainboard 2 is integrated with a connector 4 and a plurality of first interfaces.

[0050] The PC board card connector is disposed inside the column 6 and is signal-connected to the connector 4 , and the PC board card connector is exposed from the notch of the column 6 to form a PC board card insertion position.

[0051] The PC board 3 is inserted and positioned at the PC board insertion position, and internal components are integrated and arranged inside the PC board 3 .

[0052] The display part 1 is detachably arranged on the column 6 , and the display part 1 is internally integrated with peripheral devices and a plurality of second interfaces.

[0053] The number of the second interfaces is smaller than that of the first interfaces and the opening positions are adjusted according to the specifications of the display part 1 and / or the PC board 3 .

[0054] The peripheral devices transmit signals to the screen main board 2 via the interface, and transmit signals to the internal devices of the PC board 3 via the connector 4 and the PC board connection device.

[0055] The above modular all-in-one machine is designed by splitting the whole machine into three parts: display part 1, screen mainboard 2 and PC board 3, wherein the display part 1 and PC board 3 are detachable parts, and the screen mainboard 2 is a non-detachable part. The PC board 3 and the display part 1 can be replaced as needed, and the PC board 3 can be directly inserted and positioned on the screen mainboard 2. In addition, the present invention can achieve different PC cards corresponding to different display screen interfaces through multi-interface expansion and interface switching, thereby reducing the need for conversion chips between PC cards and display screens, reducing costs, and reducing the complexity of the entire hardware and structure, filling the gap in the current modular all-in-one machine screen signal transmission method.

[0056] As a specific implementation, the peripheral devices on the display part 1 are display screen 11, keypad 12, camera and microphone 13, and speaker 14. The screen mainboard 2 integrates the power supply part, keypad, camera and microphone, and speaker lines required by each module, and also includes LVDS / eDP / MIPI / V by one interface connector. The internal devices on the PC board 3 are processor 32, memory 33, hard disk 31, fan 34, USB interface 35, headphone interface and other devices.

[0057] As a further improved implementation, a plurality of through holes are provided on the column 6, a plurality of contact pins extending from the through holes are provided on the screen mainboard 2, and a plurality of contact points connected to the contact pin signals are provided on the display part 1. The signal transmission mode of the display part adopts the contact mode, and the contact points of different screens are located at different positions, which are used to connect different signals with the bracket part.

[0058] Signals are transmitted between the display part 1 and the screen main board 2 via an LVDS interface, eDP, MIPI interface, or V by one interface.

[0059] The contact pins are arranged in four rows from top to bottom, namely the first row of contact pins, the second row of contact pins, the third row of contact pins, and the fourth row of contact pins. The contact points are arranged in two rows and the positions are adjusted according to the specifications of the display part 1 and / or the PC board 3. Figure 4 As shown, when the display part adopts the LVDS interface, the position of the contacts corresponds to the first row of contact pins and the second row of contact pins. The first row of contacts are the camera, microphone and speaker contacts, and the second row are the LVDS signal contacts. Figure 5 As shown in FIG. 1 , when the display part adopts the V by one interface, the positions of the contacts correspond to the first row of contact pins and the fourth row of contact pins. The first row of contacts are the camera, microphone and speaker contacts, and the fourth row is the V by one signal contacts. Figure 6 As shown, when the display part adopts the MIPI interface, the positions of the contacts correspond to the first row of contact pins and the third row of contact pins. The first row of contacts are camera, microphone and speaker contacts, and the third row is MIPI signal contacts.

[0060] A power module 21 for supplying power to the display part 1 and the PC board 3 is disposed inside the screen mainboard 2 , and the power module 21 is electrically connected to an external power source 22 .

[0061] The PC board 3 in the present invention can be replaced according to the needs of customers. Different needs correspond to different designs of PC board processors, memory, hard disk, etc., such as Intel processors, rockchip processors and MTK processors. The present invention mainly focuses on the differences in display interfaces of different processors. Intel processors all use eDP interfaces, rockchip processors use LVDS or MIPI interfaces, and MTK processors use V by one interfaces. The PC board connection device is a gold finger 5. The connection method of the gold finger 5 and the connector 4 (similar in shape to the PCIE interface) is convenient for the client to directly perform plug-in and pull-out actions to replace the PC board 3. Other methods that can achieve signal connection are also applicable to the present invention.

[0062] The display screen 11 in the present invention can also be replaced, and different display screens use different interfaces according to their specifications, such as LVDS / eDP / MIPI / V by one interfaces.

[0063] Example 2

[0064] This embodiment discloses a design method of a modular all-in-one machine, comprising the following steps:

[0065] The integrated machine is separated into a display part 1, a screen main board 2 and a PC board 3. The screen main board 2 is formed by separating a signal design part related to the screen from the original main board.

[0066] An interface connection position is set between the display part 1 and the screen mainboard 2, and the interface connection position is applicable to display parts 1 of various specifications and models. That is, an LVDS / edp / MIPI / V by one interface is placed on the screen mainboard 2, and the display screen 11 can be replaced according to the graphics card interface requirements of the PC board.

[0067] A PC board insertion position is set on the screen mainboard 2 to insert and position the PC board 3.

[0068] The screen motherboard 2 is equivalent to an adapter board for the keypad, camera, microphone and speaker. The signal directly passes through the connector 4 and wiring on the screen motherboard 2, and then passes through the gold finger 5 to directly transmit the signal of these components to the processor. A power module 21 is placed on the screen motherboard 2, and the power supply of the PC board 3 and the display screen 11 is provided by the power module 21. In this way, no matter which display screen 11 or PC board 3 is replaced, the power supply part does not need to be changed.

[0069] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
