Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] Embodiment 1:

[0038] As Figure 1 、 Figure 2 shown, an expansion backplane 1 for a tablet computer includes a plate body 11, a plurality of connection through holes 13 opened on the plate body 11 for installing peripheral auxiliary accessories, and connectors; the connectors include one or more of a side connector 121 for setting the plate body 11 on the side of the tablet computer and a back connector 122 for setting the plate body 11 on the back of the tablet computer.

[0039] In the present invention, the design of the expansion backplane 1 can install peripheral auxiliary accessories on the connection through holes 13 on the plate body 11. Through the setting of the connection through holes 13 on the plate body 11, the installation area of the peripheral auxiliary accessories is additionally increased, thereby increasing the number of peripheral auxiliary accessories. In addition, the position of the peripheral auxiliary accessories can flexibly select the corresponding connection through holes 13 according to actual needs, and flexible and independent installation of various peripheral auxiliary accessories can be realized. In addition, the expansion backplane 1 can be set on the side of the tablet computer through the side connector 121, or the tablet computer can be set on the back of the tablet computer through the back connector 122, and flexible installation and disassembly of the expansion backplane 1 can be realized.

[0040] The connection through holes 13 are distributed throughout all or part of the plate body 11, and the connection through holes 13 include one or more of threaded through holes or positioning holes. In this embodiment, the number of connection through holes 13 is multiple, and the multiple connection through holes 13 can be distributed throughout the entire plate body 11 (for referenceFigure 1 ), or can be distributed locally on the board body 11 as needed (i.e., partial positions, refer to Figure 2 ). The threaded through holes generally select threaded holes with standard diameters, which are convenient for connecting with existing peripheral auxiliary accessories and expanding the adaptation range. In this embodiment, the threaded through holes can select 1 / 4 threaded holes 131 or 3 / 8 threaded holes 132. As Figure 1 shown, in one embodiment, multiple connecting through holes 13 are distributed throughout the entire board body 11. The multiple connecting through holes 13 include one or more of 1 / 4 threaded holes 131, 3 / 8 threaded holes 132, and positioning holes 133. The 1 / 4 threaded hole 131 and the 3 / 8 threaded hole 132 refer to the diameter dimensions of the threads. Among them, 1 / 4 means a diameter of one-fourth inch, and 3 / 8 means a diameter of three-eighths inch. These are threaded holes with standard dimensions in this field and can be used for the installation of various peripheral auxiliary accessories. In this embodiment, 1 / 4 threaded holes 131 are provided in both the central area and the edge area of the board body 11, and 3 / 8 threaded holes 132 and positioning holes 133 are provided between the central area where the 1 / 4 threaded holes 131 are provided and the edge area where the 1 / 4 threaded holes 131 are provided, which is convenient for reasonably arranging their installation positions on the premise of increasing the number of peripheral auxiliary accessories. Although this embodiment discloses the arrangement of the connecting through holes 13, it is not limited thereto, and the number and distribution positions of the 1 / 4 threaded holes 131, 3 / 8 threaded holes 132, and positioning holes 133 can be reasonably set according to actual needs. As Figure 2 shown, in another embodiment, when the connecting through holes 13 are distributed locally on the board body 11, a fixing portion 14 for fixing peripheral auxiliary accessories without threaded connection portions (such as batteries, external hard drives, or HUBs, etc., peripheral auxiliary accessories without screw rods) is also fixedly provided on the board body 11. The fixing portion 14 includes any one or two of a battery hanging plate 141 and a fixing clamp 142. The battery hanging plate 141 can adopt a V-port battery hanging plate for cooperating with V-port batteries, or can also adopt a battery hanging plate structure for cooperating with other common batteries. In order to adapt to more peripheral accessory parts, the battery hanging plate 141 and the fixing clamp 142 can adopt relevant structures in the prior art. The fixing clamp 142 is used to clamp a hard drive or a HUB (multi-port repeater). In this embodiment, the fixing portion 14 and the connecting through hole 13 installation area are arranged side by side on the board body 11. The multiple connecting through holes 13 include one or more of 1 / 4 threaded holes 131, 3 / 8 threaded holes 132, and positioning holes 133. The starting ends of the fixing portion 14 and the connecting through holes 13 are both located on the side of the board body 11 away from the tablet computer (i.e., the back of the board body 11), and the side of the board body 11 close to the tablet computer (i.e., the front of the board body 11) is a plane, which is convenient for being attached to the tablet computer.

[0041] In order to install the expansion backplane 1 on the side of the tablet computer, a side connector 121 is provided. The side connector 121 includes a first clamping groove 1211 fixedly arranged on one side or opposite sides of the plate body 11. In this embodiment, the structure of the first clamping groove 1211 is: two relatively arranged first clamping blocks 1212, and a first clamping groove 1211 is formed between the two first clamping blocks 1212. In this embodiment, the number of the first clamping grooves 1211 is two, and the two first clamping grooves 1211 are respectively arranged on opposite sides of the back of the plate body 11. A fastener 1213 for fastening the plate body 11 to the corresponding side of the tablet computer is arranged on one of the first clamping blocks 1212.

[0042] The back connector 122 includes side grooves 1222 recessed in opposite sides of the front of the plate body 11, and second clamping blocks 1221 respectively arranged opposite to the corresponding side grooves 1222. The two second clamping blocks 1221 are arranged opposite to each other. The second clamping block 1221 and the corresponding side groove 1222 form a second clamping groove for sliding cooperation with the corresponding side of the tablet computer. The two second clamping blocks 1221 are respectively arranged on opposite sides of the front of the plate body 11, that is, the second clamping groove is located on the front of the plate body 11. A fastener 1213 for fastening the plate body 11 to the corresponding side of the tablet computer is arranged on each of the second clamping blocks 1221. The fastener 1213 can specifically be a locking bolt. The axial direction of the second clamping groove is parallel to that of the first clamping groove 1211. The side connector 121 is located below the back connector 122. One side of the first clamping block 1212 away from the first clamping groove 1211 does not protrude from the front of the plate body 11, and one side of the second clamping block 1221 away from the second clamping groove does not protrude from the back of the plate body 11, so as to avoid interfering with the installation of the tablet computer. A cold shoe interface 15 is arranged at the upper part of the plate body 11 for connecting a suitable peripheral auxiliary accessory, which increases the installation types of the peripheral auxiliary accessories. The number of the cold shoe interfaces 15 is one or more. In this embodiment, the number of the cold shoe interfaces 15 is at least two, and more peripheral auxiliary accessories can be connected.
