[0032] In order to better understand the technical solutions of the present application, the specific embodiments will be described in detail below in conjunction with the drawings and the specific embodiments.

[0033] In the related art, multiple mainboards and / or expansion boards are usually installed on different bearing surfaces of the case by using multiple bolts, so that disassembly and installation are very inconvenient, and the mainboard with multiple expansion interfaces usually occupies a large installation area, which is not conducive to the space layout of the industrial computer case.

[0034] The present application takes into account the convenience of installation and the space layout characteristics of the industrial computer case, and simplifies the installation and disassembly process of the board and the mainboard by using the structure design of stacking the expansion board and the mainboard on the support piece in the industrial computer case, avoiding the inconvenience of operation caused by the traditional multiple bolt fixing method; at the same time, the mounting slot on the support piece cooperates with the clamping piece, which not only improves the installation stability, but also reduces the horizontal space occupied by the mainboard and the board, which is conducive to optimizing the space layout in the case.

[0035] Based on this, the first embodiment of the present application provides an industrial computer, which refers to Figure 1 Figure 1 The installation structure of the first embodiment of the industrial computer of the present application is shown in the figure.

[0036] In this embodiment, the industrial computer includes an industrial computer case, and the industrial computer case is provided with an expansion board 005 and a mainboard (not shown in the figure), and the expansion board 005 and the mainboard are arranged in the industrial computer case in an upper and lower positional relationship by a support piece; wherein,

[0037] The support piece includes a mounting base 003 and a support plate 001 arranged on the mounting base 003, and the mounting base 003 is installed and fixed on the box bottom 100 of the industrial computer case by the bolt 002;

[0039] For the convenience of understanding, as shown in Figure 1 , the extension carrier plate 005 can be fixed on the support member from one side of the support plate 001 along the mounting groove 008, and the mounting base 003 of the support member is fixed on the bottom of the industrial computer case (left side of the bottom) by the bolt 002. Figure 1 In the embodiment, the extension carrier plate 005 is installed in the lowest mounting groove 008, and it can be understood that the interfaces on the extension carrier plate 005 can be inserted into various components, and the mainboard can be installed above the extension carrier plate 005 by selecting the corresponding mounting groove 008 according to the height of the components on the extension carrier plate 005. It can be understood that the up-down position relationship of the extension carrier plate and / or the mainboard can be adjusted, which is not limited herein.

[0040] It can be understood that during installation, the extension carrier plate and the mainboard can be installed on the support member first, and then the support member is fixed on the bottom of the industrial computer case. This design simplifies the installation process of the carrier plate and the mainboard (only two bolts for fixing the support member need to be rotated), and avoids the cumbersome operation of traditional bolt installation. Moreover, the inner side of the support plate is provided with multiple up-down distributed mounting grooves, so that the extension carrier plate and the mainboard can be fixed in mounting grooves of different heights by the clamping pieces. At the same time, through the up-down stacked layout, the space utilization rate of the case is improved, and the compatibility and maintainability of the system are further improved, which provides higher practicability for the industrial computer in complex application scenarios.

[0041] Further, in a specific embodiment, the clamping piece includes a first clamping piece 011 provided with a buckle and a second clamping piece 012, the first clamping piece 011 is arranged on the upper side of one side of the extension carrier plate 005, and the second clamping piece 012 is arranged on the lower side of the one side of the extension carrier plate 005 opposite to the first clamping piece 011; the extension carrier plate 005 is fixed on the support plate along the mounting groove by the buckle of the first clamping piece 011 and the buckle of the second clamping piece 012 arranged opposite to the first clamping piece 011.

[0047] It can be understood that through the clamping structure of the first clamping piece and the second clamping piece, the expansion carrier plate can be quickly and stably fixed in the mounting groove of the support plate, which simplifies the installation operation and improves the reliability of the fixation. At the same time, by arranging the load-bearing protrusion and the load-bearing column at the bottom of the case, the support capacity of the expansion carrier plate and the mainboard is further enhanced, especially for the case of multi-layer stacking installation, additional support can be provided by the load-bearing column and the load-bearing clamp to avoid structural deformation or loosening caused by gravity.
