Referring to fig. 3, fig. 3 is a schematic structural diagram of a substrate assembly provided in an embodiment of the present invention, the substrate assembly 100 includes a substrate 110 and a spacer 122, and the substrate 110 may be a printed circuit board, and it should be noted that the substrate 110 in the embodiment of the present invention is illustrated by taking the printed circuit board as an example, and the substrate 110 in the embodiment of the present invention is not limited to the printed circuit board but may be other boards.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a substrate according to an embodiment of the invention, in some embodiments, a substrate 110 includes a first region 111 and a second region 112, a spacer 122 is disposed in the first region 111, the second region 112 is provided with a retaining wall layer 114, the substrate 110 is provided with a plurality of fixing holes 113 with the same size, including a main fixing hole 1131 located in the first region 111, the remaining plurality of fixing holes 113 are located in the second region 112, and the plurality of fixing holes 113 located in the second region 112 penetrate through the retaining wall layer 114.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a spacer according to an embodiment of the present invention, the spacer 122 is provided with an auxiliary fixing hole 1223, and the main fixing hole 1131 corresponds to the auxiliary fixing hole 1223, and the spacer 122 can be fixed on the substrate 110 by matching a fixing member 130 with the auxiliary fixing hole 1223 and the main fixing hole 1131, respectively.

The assembly of the first region 111 of the substrate 110 is achieved by a fixing member 130 that is cooperatively fixed with the main fixing hole 1131 of the substrate 110 through the auxiliary fixing hole 1223 of the spacer 122. The spacer 122 is fitted at the position of the first region 111 of the substrate 110, and the auxiliary fixing hole 1223 and the main fixing hole 1131 correspond to each other, to be cooperatively fixed with the fixing member 130, and the spacer 122 increases the thickness around the main fixing hole 1131 in the first region 111, so that the effective fixing portion of the fixing member increases. When assembling other fixing structures with the second region 112 of the substrate 110, the fixing member 130 can be made to have a corresponding size structure according to the other fixing structures, and meanwhile, the thickness of the gasket 122 is changed correspondingly, so that the first region 111 and the second region 112 of the substrate 11 can be assembled by adopting the same fixing structure, the assembly time of the substrate 110 is saved, and the assembly efficiency and the accuracy of the substrate 110 are improved.

In the actual assembly process, the plurality of fixing holes 113 located in the second region 112 on the substrate 110 may be assembled through a fixing structure, and specifically, the embodiment of the present invention adopts the fixing member 130 to assemble, and the plurality of fixing members 130 are respectively fixed with the fixing holes 113 on the substrate 110 through the retaining wall layer 114 in a matching manner, so as to realize the assembly of the second region 112 on the substrate 110.

Further, the thickness of the spacer 122 is the same as the thickness of the retaining wall layer 114. Specifically, the sum of the hole depth of the main fixing hole 1131 in the first region 111 and the hole depth of the auxiliary fixing hole 1223 of the spacer 122 is equal to the sum of the hole depth of the fixing hole 113 in the second region and the thickness of the retaining wall layer 114 around the fixing hole 113. Wherein the thickness of the retaining wall layer 114 around the fixing hole 113 in the second region 112 is the penetration depth of the fixing hole penetrating through the portion of the retaining wall layer 114. It should be noted that the thickness of the spacer 122 and the thickness of the retaining wall layer 114 may be within an error range. Further, the thickness of the spacer 122 is slightly greater than the thickness of the retaining wall 114, and the spacer 122 is generally made of a soft material, such as: the pad 122 is made of silica gel, rubber or foam. The spacer 122 is less compressed when fastened by the fixing member 130, and the error between the thickness of the spacer 122 and the thickness of the retaining wall layer 114 is within the range of the compression deformation degree generated when the spacer 122 is compressed by the fixing member 130.

As can be seen from the above description, the spacer 122 according to the embodiment of the present invention can increase the thickness around the main fixing hole 1131 in the first region 111 of the substrate 110, so that the fixing hole 113 in the second region 112 of the substrate 110 adopts the same fixing piece 130 as the fixing piece 130 in the first region 111, and thus the substrate 110 can be assembled by adopting the fixing piece 130 with the same specification, so as to prevent the assembly error caused by different specifications of the fixing pieces during the assembly process, further save the assembly time of the substrate 110, and improve the assembly efficiency and accuracy of the substrate 110.

The fixing member 130 may be a screw or a bolt, which should be noted that the fixing member according to the embodiment of the invention is not limited thereto.

In the actual production process, the spacer 122 may be directly processed to have the same thickness as the thickness of the retaining wall layer 114, or the thickness of the spacer 122 may be made thinner, specifically, half the thickness of the retaining wall layer 114, and the spacer 122 is bent near the middle portion to form the first spacer portion 1221 and the second spacer portion 1222, and the spacer 122 is overlapped along the bending position, so that the first spacer portion 1221 and the second spacer portion 1222 overlap. Further, the first gasket part 1221 forms a through hole, the second gasket part 1222 forms a through hole, and when the first gasket part 1221 and the second gasket part 1222 are overlapped, the through hole in the first gasket part 1221 and the through hole in the second gasket part 1222 overlap each other to form the auxiliary fixing hole.
