[0002] In recent years, as the functions of airborne electronic products become more and more complex, maintenance and upgrading occur from time to time. Therefore, each module inside the airborne equipment is designed into a standard module with the same size to facilitate replacement during later maintenance. Among them, the module for data storage (abbreviated as storage module) is one of the essential key components in the system. Due to space limitations within the system and considering internal function allocation, generally, the data processing board and the memory card are integrated in the storage module. In order to conveniently and quickly obtain the data in the memory card, users have requirements for quick disassembly, assembly and fixation of the memory card, and the memory card also needs to meet the harsh airborne environment.

[0003] In the prior art, for example, in the technical solution described in the patent document "Chassis Structure for Facilitating the Loading and Unloading of a Large-Capacity Data Storage Module" with the application number "201921160967.0", "A chassis structure for facilitating the loading and unloading of a large-capacity data storage module, including a chassis housing, a large-capacity data storage module, a motherboard, a metal groove, a smooth and wear-resistant guide rail, and a locking strip with a cam mechanism. The metal groove is arranged inside the chassis housing to guide the moving direction of the large-capacity data storage module between the chassis door and the motherboard; the smooth and wear-resistant guide rail is installed on the surface of the metal groove in contact with the large-capacity data storage module; the locking strip with a cam mechanism is installed on the large-capacity data storage module for loosening and locking the large-capacity data storage module and the metal groove." The storage module is installed in the form of a locking strip, resulting in the need to use tools during the disassembly and installation processes, which is relatively troublesome in operation and the user experience is not good.

[0041] By providing a baffle at the end of the slideway, the storage sub-card assembly is limited by the baffle to prevent the storage sub-card assembly from falling off the slideway;

[0042] Then, install the mounting panel of the guide sleeve 112 on the inner housing 700, and fixedly connect the mounting panel and the inner housing 700 with bolts, and install the pin column inside the inner housing 700 for installing the positioning pin 600. By providing the positioning pin 600 to cooperate with the guide sleeve 112, the installation of the storage sub-card assembly is limited.

[0043] As Figure 3 shown, both ends of the guiding rib 110 are inclined downward; wherein, the left end of the guiding rib 110 cooperates with the end of the spring pressing block assembly to press the guiding rib 110, and the right end of the guiding rib 110 cooperates with the sliding groove 500 to lock the guiding rib 110; the spring pressing block assembly includes a pressing block body 113, a compression spring 114 and a spring stopper 115; wherein, the middle part of the pressing block body 113 is a hollow structure, the compression spring 114 is arranged inside the pressing block body 113, a sliding groove is also provided on the pressing block body 113, and the spring stopper 115 is slidably arranged inside the sliding groove and abuts against the compression spring 114; the pressing block body 113 is also connected to the lifting device 121 through the sliding groove

[0044] Specifically, one end of the pressing block body 113 is a triangular prism structure and cooperates with the guiding rib 110 to press the guiding rib 110; an opening groove is provided in the middle of the other end of the pressing block body 113, the opening groove penetrates the pressing block body 113 along the width direction of the pressing block body 113, and an installation area is formed in the middle of the pressing block body 113 for connecting the lifting device 121. Sliding grooves are also provided on both side walls of the pressing block body 113, the sliding grooves penetrate the pressing block body 113, and round holes are also provided on the sliding grooves, and the round holes also penetrate the pressing block body 113 for installing the spring stopper 115.

[0045] The spring stopper 115 includes a stopper body and mounting columns provided on both sides of the stopper body. Among them, the stopper body abuts against the compression spring 114, and the mounting columns are arranged in the sliding groove.

[0046] The specific installation method of the spring stopper 115 and the pressing block body 113 is: respectively pass the mounting columns on both sides of the spring stopper 115 through the round holes on both sides of the pressing block body 113, and rotate the spring stopper 115 by 90°, so that the mounting columns are stuck in the sliding groove to prevent the spring stopper 115 from falling off, and the installation of the spring stopper 115 and the pressing block body 113 is completed.

[0047] Embodiment III

[0048] This embodiment is a further refinement of Embodiment II. As Figure 5 and Figure 6As shown, the lifting and prying device 121 is provided with a first rotation hole and a second rotation hole. Inside the first rotation hole, a sleeve 118 and a rotating shaft 119 are provided. In the middle of the first rotation hole, a first roller 116 is provided. Among them, the first rotation hole, the sleeve 118, and the first roller 116 are arranged in the middle of the pressing block body 113, and the rotating shaft 119 passes through the sliding groove, the sleeve 118, the first rotation hole, and the first roller 116.

[0049] In the middle of the second rotation hole, a second roller 117 is provided, and the second roller 117 is rotatably connected to the second rotation hole.

[0050] By providing a first rotation hole at the end of the lifting and prying device 121, a first roller 116 is rotatably arranged in the middle of the first rotation hole. The first roller 116 contacts the spring stopper 115, and the spring stopper 115 is pushed by the first roller 116 to move, so that the spring stopper 115 presses the guiding rib 110.

[0051] The first roller 116 and the spring stopper 115 are in sliding friction. When the first roller 116 pushes the spring stopper 115 to move, the rigid contact between the first roller 116 and the spring stopper 115 can be effectively reduced, making the movement of the spring pressing block assembly smoother and reducing the vibration when the spring pressing block assembly moves.

[0052] Limit parts are provided at both ends of the rotating shaft 119, and the limit parts are used for limiting the rotating shaft 119.

[0053] As Figure 2 shown, grooves are provided on both sides of the base 900, and the limit parts of the rotating shaft 119 are arranged in the grooves and move in the grooves.

[0054] The second rotation hole and the second roller 117 are connected by a rivet 125.

[0055] The second rotation hole is arranged at the end of the lifting and prying device 121. The second roller 117 and the second rotation hole are connected by a rivet 125, and the second roller 117 is rotatably connected to the second rotation hole through the rivet 125.

[0056] As Figure 8 shown, a limit groove 127 is arranged inside the outer housing 100. The second roller 117 is arranged inside the limit groove 127. The limit groove 127 is used to contact the second roller 117, and the lifting and prying device 121 is limited by contacting the second roller 117.

[0057] Specifically: When installing the storage sub - card assembly, it is necessary to fix the lifting device 121. By rotating the lifting device 121 around the rotating shaft 119, the second roller 117 is driven to rotate; when the lifting device 121 rotates a certain angle (such as 30°), the second roller 117 will contact one side surface of the limiting groove 127, thereby restricting the rotation of the lifting device 121. Continuing to drive the lifting device 121 to rotate will cause the first roller 116 to push the spring pressing block assembly to move, thereby pressing the guiding rib 110 of the storage sub - card assembly tightly.

[0058] When removing the installation of the storage sub - card assembly, it is necessary to pull up the lifting device 121. By rotating the lifting device 121 around the rotating shaft 119, the second roller 117 is driven to rotate; when the lifting device 121 rotates a certain angle (such as 30°), the second roller 117 will contact the other side surface of the limiting groove 127, thereby restricting the rotation of the lifting device 121. If the lifting device 121 is continuously driven to rotate, the storage sub - card assembly will be pulled out from the sliding groove 500.

[0059] An installation groove is also provided on the lifting device 121. The locking tongue 122 is slidably arranged inside the installation groove. A connecting column is provided at the end of the locking tongue 122. A return spring 123 is sleeved outside the connecting column, and the end of the return spring 123 abuts against the inner wall of the installation groove; a buckle 124 is also provided on the outer wall of the lifting device 121. The buckle 124 passes through the lifting device 121 and is connected to the locking tongue 122, and is fixedly connected by a fastening screw 120. So that the buckle 124 and the locking tongue 122 are fixed under the action of the fastening screw 120, thereby realizing the movement of the buckle 124 driving the locking tongue 122.

[0060] By setting the buckle 124 to drive the locking tongue 122 to slide inside the installation groove, the locking tongue 122 is retracted. By pushing the lifting device 121 to rotate, and finally making the locking tongue 122 located inside the limiting boss 126 of the base 900, the buckle 124 is released. The locking tongue 122 pops out under the action of the return spring 123 to limit the lifting device 121.

[0061] The sliding track includes a first sliding track 300 and a second sliding track 400. The first sliding track 300 and the second sliding track 400 are respectively arranged on the left and right sides of the outer housing 100.

[0062] Furthermore, two sets of lifting devices 121 are provided. The two sets of lifting devices 121 are respectively arranged on both sides of the storage sub - card assembly. The two sets of lifting devices 121 cooperate with the first sliding track 300 and the second sliding track 400 respectively to jointly press and fix the storage sub - card assembly.

[0063] Such as Figure 4 and 7As shown, a pressing part is provided in the chute 500 of the first slideway 300 and the second slideway 400. The pressing part is arranged obliquely downward and cooperates with the end of the guiding rib 110. When the pressing block body 113 presses the guiding rib 110 through extrusion, the guiding rib 110 will also extrude the chute 500 and cooperate with the pressing part of the chute 500, and the guiding rib 110 is pressed by the pressing part of the chute 500.

[0064] The two ends of the guiding rib 110 are respectively acted on by the pressing block body 113 and the pressing part of the chute 500, and the pressing of the guiding rib 110 is jointly realized, so as to improve the fixing effect and make the installation more stable.

[0065] The working principle of the present invention is as follows: when installing the storage sub-card assembly, the guiding rib 110 provided on the inner housing 700 needs to be inserted into the chute 500 of the slideway, and the storage sub-card assembly is positioned by the cooperation of the positioning pin 600 provided on the baffle and the guide sleeve 112 on the inner housing 700;

[0066] By rotating the lifting device, the lifting device 121 rotates around the rotating shaft 119 and drives the second roller 117 to rotate. When the lifting device 121 rotates a certain angle (such as 30°), the second roller 117 will contact the side surface of the limiting groove 127, thereby restricting the rotation of the lifting device 121. If the lifting device 121 is continuously driven to rotate, the first roller 116 will push the spring pressing block assembly to move, so as to press the guiding rib 110 of the storage sub-card assembly.

[0067] When removing the installation of the storage sub-card assembly, the lifting device 121 needs to be pulled up to make the lifting device 121 rotate around the rotating shaft 119 and drive the second roller 117 to rotate; when the lifting device 121 rotates a certain angle (such as 30°), the second roller 117 will contact the lower surface of the limiting groove 127, thereby restricting the rotation of the lifting device 121. If the lifting device 121 is continuously driven to rotate, the storage sub-card assembly will be pulled out of the chute 500, and if the lifting device 121 is continuously pulled, the lifting device 121 and the storage sub-card assembly can be pulled out of the interior of the device housing together, which facilitates the removal of the storage sub-card assembly.
