Description

Technical Field

[0001] The utility model relates to a memory anti-vibration device, and is particularly used to prevent a memory module arranged on a mainboard from being vibrated and falling off. Background Art

[0002] With the advancement of science and technology and the development of society, trains, public transportation and other means of transportation have become an important way for people to travel in their daily lives. To ensure that the electronic equipment of these means of transportation can operate stably and reliably, they must comply with strict vibration test standards (for example, IEC 61373, GB / T 21562-2008). However, the widely used memory (DDR) currently mostly adopts a snap-on design rather than a locking design, resulting in its weak shock resistance. In actual applications, memory often has problems such as loose structure and poor contact due to vibration or falling, which seriously affects the reliability and service life of the equipment. This has become a problem to be solved in the design and manufacture of electronic equipment in the transportation field.

[0003] In order to solve the problem of weak anti-seismic ability of memory, common fixing methods are mainly glue fixing and cable tie fixing. Glue fixing is to apply glue between the memory and the motherboard, and use the viscosity of the glue to fix the memory; while cable tie fixing is to tie the memory and the motherboard together with cable ties, and use the tight binding force of the cable ties to fix the memory. However, both fixing methods have obvious defects. First, they are extremely inconvenient for the installation and assembly process of the memory, and require a lot of man-hours and manpower. Secondly, these two fixing methods are one-time. Once the memory needs to be replaced or upgraded, the original fixing method must be destroyed, and then glue or tie it again, which not only affects the assembly efficiency, but also increases the maintenance cost. Therefore, a new memory fixing solution is needed that can provide reliable anti-seismic effect and facilitate the installation and replacement of memory. Utility Model Content

[0004] In view of this, the utility model provides a memory anti-vibration device for preventing a memory module arranged on a mainboard of a vehicle from falling off due to vibration. The memory anti-vibration device comprises a fixing plate body, which is covered and fixed on the plane of the mainboard. The fixing plate body has a mounting opening larger than the size of the memory module, and at least one guide rail and at least one fixing hole are respectively provided at two ends adjacent to the mounting opening; two anti-vibration fixing members are respectively installed on two opposite sides of the mounting opening, and the anti-vibration fixing members are in the shape of a sheet, and are formed with fixing slots relative to the positions of the fixing holes, one side of which is formed with a guide rail plug-in for mounting on the guide rail, and the other side is bent to form a supporting portion that abuts against one end of the memory module; wherein, after the guide rail plug-in is installed on the guide rail, the anti-vibration fixing member can be moved back and forth along the guide rail through the guide rail plug-in, and the anti-vibration fixing member is locked by passing the fixing screws through the fixing slots and the fixing holes, so that the anti-vibration fixing member is limited on the fixing plate body and the memory module is prevented from loosening through the abutting portion.

[0005] In one embodiment, the side edge of the anti-vibration fixing piece is vertically bent to form a hand-pick piece for the user to push the anti-vibration fixing piece.

[0006] In one embodiment, the fixing plate is formed with two parallel guide rails, and the anti-vibration fixing member is formed with two guide rail plug-ins matching the rails.

[0007] In one embodiment, the two guide rail plug-ins are respectively formed with undercuts to prevent the anti-vibration fixing member from being separated from the fixing plate when the fixing screws are removed.

[0008] In one embodiment, the distance between the two guide rails is the same as the distance between the two guide rail inserts.

[0009] In one embodiment, the fixing plate is formed with a plurality of openings corresponding to the electronic components on the main board, so as to avoid interference with the electronic components when the fixing plate is covered and fixed on the main board.

[0010] In one embodiment, both ends of the memory module are provided with a toggle element that can be toggled to remove the memory element, and after the abutting portion abuts against one end of the memory module, the toggle element cannot be toggled.

[0011] Through the above method, the memory anti-vibration device of the utility model does not need to change the original wiring of the motherboard, and can be fixed on any existing motherboard by the fixed plate body and the anti-vibration fixing parts. It can not only provide reliable anti-vibration effect for the memory, but also facilitate the installation and replacement of the memory. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the structure decomposition of the memory anti-vibration device 10 of the utility model; Figure 2 1 is a three-dimensional structural diagram of the memory anti-vibration device 10 of the present invention. The memory anti-vibration device 10 of the present invention comprises a mainboard 100 , a fixing plate 110 , an anti-vibration fixing member 120 , and fixing screws 125 .

[0024] like Figure 1As shown, a memory module 101 and a toggle element 102 are arranged on the mainboard 100. The memory module 101 is arranged on the mainboard 100 to store data and programs required for computer operation. Generally speaking, the memory module 101 is inserted into the memory slot on the mainboard 100 and connected to the mainboard 100 through the contacts of the memory slot, but the present invention does not limit the specifications of the memory module 101 and the connection method with the mainboard 100. The toggle element 102 is arranged at both ends of the memory module 101. The memory module 101 can be removed from the mainboard 100 by pulling the toggle element 102, so that the user can install and remove the memory module 101. In some embodiments, the toggle element 102 includes a rotatable handle and a locking mechanism connected thereto, but the present invention is not limited thereto. That is, when the corresponding toggle elements 102 on both sides of the memory module 101 are in the open state, the memory module 101 can be pulled out from the motherboard 100; on the contrary, when the corresponding toggle elements 102 on both sides of the memory module 101 are in the fastened state, the memory module 101 is fixed on the motherboard 100. The abutment portion 121 of the present invention is to block the toggle element 102 from being moved, thereby locking and fixing the memory module 101.

[0025] The fixed plate 110 is mainly covered and fixed on the mainboard 100, and the fixed plate 110 has an installation opening 111 larger than the size of the memory module 101 on the mainboard 100. Specifically, the fixed plate 110 can be covered and fixed on the mainboard 100 in a variety of ways, such as locking, snapping, pasting or other suitable fixing methods, and the present invention is not limited thereto. It must be noted that in different embodiments, the size and specification of the memory module 101 mounted on the mainboard 100 may be different. The installation opening 111 on the fixed plate 110 of the present invention can be customized according to the size of the memory module 101 actually used, that is, the fixed plate 110 of the present invention can be customized according to various sizes of mainboards 100, so that the fixed plate 110 can cover various sizes of mainboards 100. The mainboard 100 in this article refers to any mainboard 100 containing a memory module 101, and the present invention does not limit the size or appearance of the mainboard 100.

[0026] Specifically, the length and width of the mounting opening 111 can be customized according to the length and width of the memory module 101, so that the mounting opening 111 can just accommodate the memory module 101. At the same time, the position of the mounting opening 111 on the fixed plate 110 can also be adjusted according to the specific position of the memory module 101 on the mainboard 100 to ensure that when the fixed plate 110 is covered and fixed on the mainboard 100, the mounting opening 111 can be accurately aligned with the memory module 101. Advantageously, the position and size of the mounting opening 111 can be flexibly manufactured, so that the memory anti-vibration device 10 of the utility model can be widely used in mainboards 100 of various sizes and specifications. This flexible and customizable design improves the versatility and applicability of the memory anti-vibration device 10, so that it can be widely used in various types of mainboards 100.

[0027] Specifically, at both ends of the mounting opening 111 of the fixed plate body 110, at least one guide rail 112 and at least one fixing hole 113 are provided. The guide rail 112 is a groove or a groove formed on the fixed plate body 110, and the groove or the groove is a slot hole penetrating the plate body, and is used to cooperate with the guide rail plug-in 122 on the anti-seismic fixing member 120. The number, width and depth of the guide rail 112 can be designed according to actual needs to provide sufficient strength and stability.

[0028] Specifically, the anti-vibration fixing parts 120 are respectively installed on two opposite sides of the installation opening 111. The anti-vibration fixing parts 120 are generally sheet-like structures. A fixing slot hole 123 is formed at a position corresponding to the fixing hole 113 on the anti-vibration fixing part 120. It should be noted that the fixing slot hole 123 and the fixing hole 113 are aligned to facilitate the installation of the fixing screw 125. One side of the anti-vibration fixing part 120 is formed with a guide rail plug-in 122 for installation on the guide rail 112, and the other side is bent to form a supporting portion 121 that abuts against one end of the memory module 101. Specifically, the guide rail plug-in 122 is a protruding structure formed on one side of the shock-resistant fixing member 120, and its shape and size match the guide rail 112 on the fixing plate 110. The abutment portion 121 is a bending structure formed on the other side of the shock-resistant fixing member 120, which is used to assist the shock-resistant fixing member 120 to abut against the toggle elements 102 at both ends of the memory module 101, making it impossible for the toggle elements 102 to be moved, thereby achieving the purpose of tightening the memory module 101 and realizing effective fixation and shock-proof protection of the memory module 101.

[0029] To further explain, the fixing hole 113 is a through hole formed on the fixing plate 110, and the fixing slot 123 is an elongated through hole formed on the anti-vibration fixing member 120. The fixing hole 113 cooperates with the fixing slot 123, and the anti-vibration fixing member 120 is locked on the fixing plate 110 by passing the fixing screw 125 through the fixing slot 123. In some embodiments, the guide rail plug 122 on the anti-vibration fixing member 120 slides to a suitable position through the guide rail 112 on the fixing plate 110; that is, the abutting portion 121 abuts against the toggle element 102 at both ends of the memory module 101, and the fixing screw 125 passes through the fixing slot 123 and the fixing hole 113 in sequence. After tightening the fixing screw 125, the anti-vibration fixing member 120 is completely locked on the fixing plate 110, thereby preventing the memory module 101 from loosening.

[0030] In some embodiments, a barb structure may be further provided on the anti-seismic fixing member 120 to further improve the reliability of the connection between the anti-seismic fixing member 120 and the fixed plate body 110. Specifically, a barb structure is formed at the end of the guide rail plug-in. In a state of use, the anti-seismic fixing member 120 is installed on the guide rail 112 of the fixed plate body 110 through the guide rail plug-in 122, and the fixing screw 125 passes through the fixing slot 123 and the fixing hole 113, and the anti-seismic fixing member 120 is locked to the fixed plate body 110 through the fixing screw 125. At this time, the barb structure on the guide rail plug-in 122 is located inside the guide rail 112 and will not affect the sliding of the anti-seismic fixing member 120. In another use state, when the fixing screw 125 needs to be removed in order to adjust the position of the anti-seismic fixing member 120, the anti-seismic fixing member 120 is loose on the guide rail 112 due to the lack of the fixing screw 125. At this time, if the guide rail plug-in 122 lacks a barb structure, the anti-seismic fixing member 120 is likely to be directly detached from the guide rail 112, causing inconvenience in subsequent reinstallation; that is, through the barb structure on the guide rail plug-in 122, even if the fixing screw 125 is loosened or removed, the barb structure on the guide rail plug-in 122 will abut against the bottom outer and inner walls of the guide rail 112 to prevent the anti-seismic fixing member 120 from detaching from the guide rail 112. When it is necessary to re-lock the anti-seismic fixing member 120 on the fixed plate 110, it is only necessary to slide the anti-seismic fixing member 120 along the guide rail 112 to a position and re-tighten the fixing screw 125. In other words, the barb structure on the rail plug 122 plays a role of temporary fixing, preventing the anti-seismic fixing member 120 from falling off the fixing plate 110, and improving the reliability of the connection between the anti-seismic fixing member 120 and the fixing plate 110. Advantageously, since the anti-seismic fixing member 120 is always kept on the fixing plate 110, it will not fall off or be lost due to the removal of the fixing screw 125, which greatly facilitates the subsequent installation operation and improves the practicality.

[0031] In some embodiments, two parallel guide rails 112 may be provided on the fixed plate 110, and correspondingly, two guide rail plug-ins 122 are also provided on the anti-seismic fixing member 120 to cooperate therewith, and the spacing between the two guide rails is the same as the spacing between the two guide rail plug-ins. Advantageously, by increasing the number of guide rails 112 and guide rail plug-ins 122, the sliding stability and reliability of the anti-seismic fixing member 120 on the fixed plate 110 can be further improved.

[0032] In some embodiments, the fixed plate 110 may also be provided with a plurality of openings corresponding to the electronic components on the mainboard 100, for example, fan openings, power supply openings, expansion slot openings and other openings, but the present invention is not limited thereto. The provision of these openings can prevent the fixed plate 110 from interfering with other electronic components on the mainboard 100 during installation, thereby improving the applicability and compatibility of the anti-vibration device. Advantageously, through this design, the anti-vibration device of the present invention can be conveniently installed on various mainboards 100 without modifying or adjusting the mainboard 100.

[0033] In some embodiments, a hand paddle 124 is formed on the side of the anti-vibration fixing member 120. Specifically, the hand paddle 124 is a protrusion on the anti-vibration fixing member 120, and its shape is convenient for the user's fingers to grasp. When the position of the anti-vibration fixing member 120 needs to be adjusted, the user can push or grasp the hand paddle 124 with his fingers, thereby driving the anti-vibration fixing member 120 to slide along the guide rail 112. Advantageously, this design makes the operation of the anti-vibration fixing member 120 simpler and more convenient, and can be completed without the aid of any tools.

[0034] See also Figure 3A , Figure 3A This is a schematic diagram of the unlocked state of the anti-seismic fixing member of the utility model, showing that the two anti-seismic fixing members 120 are in the unlocked state, the two anti-seismic fixing members 120 slide outwards correspondingly through the guide rails 112 and the guide rail plug-ins 122, and the toggle elements 102 at both ends of the memory module 101 are in the open state.

[0035] In detail, when the two anti-vibration fixing members 120 slide outward along the guide rails 112 respectively, the abutment portion 121 gradually moves away from the toggle element 102 until the toggle element 102 is no longer blocked by the abutment portion 121, and the user can freely move the toggle element 102, for example, to open the toggle element 102 to remove the memory module 101.

[0036] In some embodiments, when the user wants to remove the memory module 101, after loosening the fixing screw 125, the user pushes the two anti-vibration fixing members 120 outward through the hand paddle 124 until the toggle element 102 is no longer blocked by the abutment portion 121. At this time, the user can easily pull the two opposing toggle elements 102 apart to remove the memory module 101 between the two toggle elements 102. Advantageously, during the process of the anti-vibration fixing member 120 sliding to the outside, the guide rail plug-in 122 is always inserted into the guide rail 112, ensuring that the anti-vibration fixing member 120 will not deviate during the sliding process. At the same time, the barb structure on the guide rail plug-in 122 also plays a role in preventing it from falling off. Even when the fixing screw 125 is completely loosened, the barb structure can fix the anti-vibration fixing member 120 on the fixing plate 110 to prevent the anti-vibration fixing member 120 from completely falling off.

[0037] See also Figure 3B , Figure 3B This is a schematic diagram of the locking state of the anti-seismic fixing member of the utility model, showing that the two anti-seismic fixing members 120 are in the locked state, the two anti-seismic fixing members 120 slide inwardly correspondingly through the guide rails 112 and the guide rail plug-ins 122, and the toggle elements 102 at both ends of the memory module 101 are in a fastened state.

[0038] Specifically, after fastening the corresponding toggle element 102 , the user pushes the hand paddle 124 to slide the two anti-vibration fixing members 120 inward along the guide rail 112 , and the abutting portion 121 gradually approaches the toggle element 102 until the abutting portion 121 abuts against the toggle element 102 , thereby limiting the operation of the toggle element 102 .

[0039] In some embodiments, when a user wants to install a memory module 101, after inserting the memory module 101 into the motherboard 100, the user pulls and fastens the corresponding toggle elements 102 at both ends of the memory module 101, and pushes the hand paddles 124 to push the two anti-vibration fixing members 120 inward and gradually approach the toggle elements 102 until they abut against the toggle elements 102, making it impossible for the toggle elements 102 to be moved. After tightening the fixing screws 125, the anti-vibration fixing members 120 are limited on the fixing plate 110, and the abutting portion 121 prevents the memory module 101 from loosening, thereby completing the anti-vibration fixing of the memory module 101 by the anti-vibration fixing members 120. Advantageously, the memory module 101 is not only fixed by the toggle element 102, but also locked by the fixing slot 123 and the fixing hole 113 so that the abutment portion 121 of the anti-vibration fixing member 120 tightly supports the toggle element 102, thereby effectively preventing the memory module 101 from loosening or falling off due to vibration or impact during use.

[0040] In summary, the memory anti-vibration device 10 proposed in the embodiment of the utility model allows the user to adjust the anti-vibration fixing member 120 to a suitable position to remove the memory module 101 by a simple sliding operation. In addition, the memory module 101 is locked and anti-vibration protected by the interaction between the abutment portion 121 and the toggle element 102, and the fixing slot 123 and the fixing hole 113 are locked by the fixing screw 125. This not only improves the installation and fixing efficiency of the memory module 101, but also greatly improves the stability of the motherboard.
