Technical Field

[0001] The present invention relates to the technical field of embedded computers, in particular to an embedded reinforced computer. Background Art

[0002] Embedded reinforced computers are embedded reinforced special-purpose computer technology. The word "special" means it is aimed at a specific application, such as networking, communication, audio, video, industrial control, etc. From an academic perspective, embedded systems are application-centric, based on computer technology, and have customizable software and hardware. They are suitable for special-purpose computer systems that have strict requirements on functions, reliability, cost, size, and power consumption in application systems. It generally consists of four parts: embedded microprocessors, peripheral hardware devices, embedded operating systems, and user applications.

[0044] Specifically, such as Figures 1-8 As shown, an arc rod 209 is installed on the side of the limiting column 207 for sliding through, and both ends of the arc rod 209 are fixedly connected to the inner walls of both ends of the arc groove 208. An elastic part 210 is installed on the outer wall of the arc rod 209 for sliding, and both ends of the elastic part 210 are fixedly connected to the inner wall of one end of the arc groove 208 and the outer wall of the limiting column 207 respectively.

The inner walls of the two through grooves 214 are slidably connected to the outer walls of the two cylinders 212 respectively.

[0047] In this embodiment, by providing a moving bar 213 and a through slot 214 , when the moving bar 213 moves, the through slot 214 drives the cylinder 212 and the fixed frame 211 to move, and the cylinder 212 slides on the inner wall of the through slot 214 , further driving the card bar 206 to rotate.

[0048] Specifically, such as Figures 1-8 As shown, a connecting plate 215 is fixedly installed on the bottom surface of the movable bar 213 , and the lower end of the connecting plate 215 slides through the inner wall of the lower end of the cavity 202 and extends into the interior of the slot body 201 . The bottom surface of the connecting plate 215 is fixedly connected to the top surface of the fixing block 216 .

[0049] In this embodiment, by pulling the fixed block 216 , the connecting plate 215 and the movable bar 213 are moved downward, and the clamping bar 206 is further driven out of the clamping slot 217 , so that the mounting plate 104 can be easily disassembled.

[0050] The stabilizing mechanism 3 is arranged inside the mounting plate 104. The stabilizing mechanism 3 includes a stabilizing plate 303 located inside the mounting plate 104. The top surface of the stabilizing plate 303 is provided with an abutting groove 312. The outer wall of the stabilizing plate 303 is fixedly installed with a limiting strip 304. The stabilizing mechanism 3 is used to abut and fix the fixing block 216.

[0051] Specifically, such as Figures 1-9 As shown, a cavity 301 is opened on the inner wall of one side of the groove body 201, and the side of the stabilizing plate 303 is slidably connected to the inner wall of the cavity 301 and the inner wall of the groove body 201. A limiting groove 302 is opened on the inner wall of the groove body 201, and the inner wall of the limiting groove 302 is slidably connected to the side of the limiting bar 304.

[0052] In this embodiment, the cavity 301 is provided so that the stabilizing plate 303 can move, and the limiting grooves 302 and limiting bars 304 are provided to limit the stabilizing plate 303, so that the stabilizing plate 303 moves more stably.

[0053] Specifically, such as Figures 1-9As shown, an abutment block 313 is fixedly installed on the inner wall of the abutment groove 312, a stabilizing groove 311 is provided on the bottom surface of the fixed block 216, the outer wall of the abutment block 313 is slidably connected to the inner wall of the stabilizing groove 311, the inner wall of the abutment groove 312 is slidably connected to the side of the fixed block 216, two movable grooves 305 are provided inside the stabilizing plate 303 and the limiting bar 304, and buckles 306 are slidably installed on the inner walls of the two movable grooves 305 respectively, and a clamping hole 307 is provided on the inner wall of one side of the limiting groove 302, and the two clamps 306 are clamped with the clamping hole 307.

[0054] In this embodiment: by providing an abutment block 313, an abutment groove 312 and a stabilizing groove 311, the fixing block 216 is abutted and limited, so that the fixing block 216 is not likely to move downward, ensuring that the card strip 206 is not likely to loosen from the card groove 217, and the provided buckle 306 and card hole 307 are used to fix the stabilizing plate 303.

[0055] Specifically, such as Figures 1-9 As shown, control blocks 310 are fixedly installed on the sides of the two clips 306, and two sliding columns 308 are slidably installed on the top surfaces of the two clips 306. The two ends of the multiple sliding columns 308 are fixedly connected to the inner walls of the two moving grooves 305 at both ends, and elastic parts 309 are slidably installed on the outer walls of the multiple sliding columns 308. The two ends of the multiple elastic parts 309 are fixedly connected to the inner walls of the two moving grooves 305 and the sides of the two clips 306.

[0056] In this embodiment, the buckles 306 are limited by the sliding column 308 , and the second elastic member 309 applies elastic force to the two buckles 306 .

[0057] The specific solution is as follows: when the internal components of the embedded reinforced computer are damaged, the control block 310 is pressed, the two clips 306 are moved toward the middle and the elastic member 2 309 is squeezed, the clip 306 is loosened from the clip hole 307, and the control block 310 is pulled to drive the stabilizing plate 303 to move, and the abutting groove 312 and the abutting block 313 on the stabilizing plate 303 are no longer limited to abutting the stabilizing groove 311 and the fixed block 216, and the fixed block 216 is pulled. The fixed block 216 drives the connecting plate 215 and the moving bar 213 to move downward, and the through groove 214 on the moving bar 213 drives the cylinder 212 and the fixed frame 211 to move. Due to the fixation of the card strip 206 by the rotating shaft 205 and the limitation of the card strip 206 by the arc groove 208 and the limiting column 207 on the card strip 206, the cylinder 212 moves on the inner wall of the through groove 214 and drives the card strip 206 to rotate, and the card strip 206 rotates from a vertical state to a horizontal state. When the fixing plate 104 is in the flat state, the clip 206 is moved out of the clip slot 217, so that the mounting plate 104 can be easily and quickly disassembled without the help of special tools, and the internal components can be disassembled, thereby improving the efficiency of maintenance and reducing the maintenance cost and time cost. After the maintenance is completed, the fixing block 216 is pulled to install the mounting plate 104 in the mounting groove 103, and the fixing block 216 is loosened. Under the elastic action of the elastic member 210, the clip 206 is engaged with the clip slot 217, thereby fixing the mounting plate 104, and pushing the stabilizing plate 303 so that the clip 306 is engaged with the card hole 307. At this time, the stabilizing plate 303 is fixed, and the abutting groove 312 and the abutting block 313 on the stabilizing plate 303 abut and limit the fixing block 216 and the stabilizing groove 311, so that the fixing block 216 is not easy to move, further ensuring the stability of the clamping of the clip 206 and the clip slot 217.
