Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of fixing memory cards of electronic devices, and in particular to a bracket, a mainboard device and an electronic device for simultaneously fixing cards to be fixed at two heights. Background Art
[0002] In electronic devices, due to the limited space of some motherboards, when two M.2 cards of different heights need to be placed on the motherboard, the two cards are stacked and fixed during design to save space on the motherboard. When the two cards are stacked together, a stud needs to be welded on the motherboard first, and then when fixing the lower card (such as a Wifi card), a hexagonal stud is used to lock it on the welded motherboard stud to fix the lower card. Finally, when assembling the upper card (such as an SSD card), a screw is used to lock it on the hexagonal stud to complete the fixing of the upper card.
[0003] The disadvantages of this assembly method are that, first, the lower card needs to be fixed with a hexagonal socket, and when the upper card is assembled, the screws are locked, which requires different tools to be switched on the production line, affecting efficiency. Second, when removing the screws that fix the upper card, the hexagonal studs below will rotate together, making it difficult to remove the screws. Third, the two cards are selectively configured according to actual needs, which means that when users disassemble and replace them according to their needs, they need to use two tools, a hexagonal socket and a screwdriver. Users may not have the corresponding tools, and if the manufacturer assembles the tools, the cost will increase. Fourth, if the lower card is a wifi card, the antenna of the wifi card is at risk of falling off because there is no fixed structure on the top. Therefore, it is necessary to improve the current assembly and fixing method. Utility Model Content

[0053] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0054] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.
[0055] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.
[0056] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0057] According to an embodiment of the present disclosure, the utility model provides a bracket for simultaneously fixing two cards of different heights. Figure 1-4As shown, the bracket 1 for simultaneously fixing two cards to be fixed at different heights comprises a bracket body 10; the bracket body 10 has a first side and a second side opposite to each other; a first opening slot 11 is formed on the first side, and the first opening slot 11 is used for detachably installing a first card to be fixed 3; a second opening slot 12 is formed on the second side, and the second opening slot 12 is used for accommodating a second card to be fixed 4, so that the second card to be fixed 4 and the first card to be fixed 3 are arranged in an upper and lower position;
[0058] The bracket body 10 is also formed with a first connection portion 13 and a second connection portion 14 . The first connection portion 13 is used for detachably connecting to the mainboard structure 2 . The second connection portion 14 detachably connects the second card to be fixed 4 located above to the mainboard structure 2 via the fixing member 5 .
[0059] The bracket 1 has a simple structure, a small size, and is easy to install. It can be set in a small space to fix two cards to be fixed with different height requirements. For example, the bracket 1 can be installed on the mainboard structure 2 of an electronic device without occupying the extra space of the mainboard structure 2. The opening grooves on the upper and lower opposite sides of the bracket 1 are respectively used to install the cards to be fixed, so that the two cards to be fixed on the mainboard structure 2 are fixed in the upper and lower positions. The two cards to be fixed are stacked together, which effectively saves space on the mainboard structure. In addition, the bracket 1 can be connected to the mainboard structure 2 through two connecting parts, which saves the fixings used during installation, and the assembly is simple and efficient.
[0060] For example, combined with Fig.14 As shown, the mainboard structure 2 includes a mainboard 21, a mounting hole 211 provided on the mainboard 21, a mainboard stud 23 provided on the mainboard 21, and a spacer 22 provided on the mainboard 21. The spacer 22 is a fixing member, which is usually used to fix the interval between the mainboard 21 and the chassis of the electronic device to ensure that the mainboard 21 does not contact the metal of the chassis. The spacer can be a patch stud (standoff), and the mainboard 21 can be a PCB board.
[0061] For example, the first card to be fixed 3 and the second card to be fixed 4 may be a wifi card or an SSD card (solid state drive).
[0062] In one embodiment, Figure 2-4 As shown, the first opening slot 11 includes first limiting surfaces 111, which are respectively formed on the left and right sides of the first opening slot 11, and are used to limit the left-right movement of the first to-be-fixed card 3;
[0063] The second limiting surfaces 112 are respectively formed on the upper and lower sides of the first opening slot 11, and are used to limit the movement of the first to-be-fixed card 3 in the up and down directions;
[0064] The third limiting surface 113 is formed at the front end side of the first opening slot 11 and is used to limit the movement of the first to-be-fixed card 3 in the front-to-back direction.
[0065] In this embodiment, the first opening slot 11 is provided with three limiting surfaces (including a first limiting surface, a second limiting surface and a third limiting surface), so that after the first card to be fixed 3 is installed in the first opening slot 11, these three limiting surfaces can effectively limit the movement of the first card to be fixed 3 in the left and right, up and down, and front and back directions.
[0066] In order to facilitate the installation and removal of the first to-be-fixed card 3, the first to-be-fixed card 3 can be engaged in the first opening slot 11, and with the assistance of three limiting surfaces, the first to-be-fixed card 3 can be restricted in the first opening slot 11. This installation method is simple and easy to operate. Figure 5-6 As shown, for example, when the first card 3 to be fixed is a wifi card, the wifi card is engaged in the first opening slot 11, and the first limiting surface 111, the second limiting surface 112 and the third limiting surface 113 limit the left and right sides, upper and lower sides and front side of the wifi card to prevent the wifi card from moving.
[0067] For example, Figure 2 As shown, the third limiting surface 113 can be formed in the following manner: a first convex portion 114 is formed by extending outward from one of the first limiting surfaces 111, and the third limiting surface 113 is formed on the end surface of the first convex portion 114. When the first to-be-fixed card 3 is engaged in the first opening slot 11, the first end of the first to-be-fixed card 3 is in contact with the third limiting surface 113, and then the second end of the first to-be-fixed card 3 is connected to the first connector 6 of the mainboard structure 2, as shown in FIG. Fig.14 As shown, the connection and communication between the first card to be fixed 3 and the mainboard structure 2 are realized. Therefore, the third limiting surface 113 cooperates with the first connector 6 to limit the movement of the first card to be fixed 3 in the front-back direction, and prevents the second end of the first card to be fixed 3 from falling off from the first connector 6, causing the risk of signal interruption.
[0068] In one embodiment, Figure 3 , Figure 8 As shown, the second opening slot 12 has a fourth limiting surface 121, which is formed on the left and right sides of the second opening slot 12 respectively, and is used to limit the left-right movement of the second to-be-fixed card 4.
[0069] In this embodiment, if Figure 3 , Figure 8As shown, the second opening slot 12 of the bracket body 10 opens upwards and is used to accommodate the second card to be fixed 4. Therefore, when the second card to be fixed 4 is placed in the second opening slot 12, in order to prevent the second card to be fixed 4 from moving, a fourth limiting surface 121 is formed on the left and right sides of the second opening slot 12 to limit the left and right movement of the second card to be fixed 4. This preliminarily serves the purpose of simply fixing the second card to be fixed 4. In addition, because a second connecting portion 14 is formed on the bracket body 10, the second connecting portion 14 can detachably connect the second card to be fixed 4 to the main board structure 2 through the fixing member 5. The fixation of the second card to be fixed 4 to the main board structure 2 is further strengthened, so that the second fixed card 4 will not fall off the bracket 1.
[0070] For example, Figure 3 , Fig.17 , Fig.18 As shown, when the second card to be fixed 4 is installed on the mainboard structure 2, the second end of the second card to be fixed 4 is first connected to the second connector 7 of the mainboard structure 2, and then the second card to be fixed 4 is rotated so that the first end is placed in the second opening slot 12. Therefore, in order to limit the movement of the second card to be fixed 4 in the front-to-back direction and prevent the second end of the second card to be fixed 4 from falling off from the second connector 7, at least one rib 122 is also provided on the front end side of the second opening slot 12, and a fifth limiting surface 123 is formed on the end surface of the rib 122 to limit the movement of the second card to be fixed 4 in the front-to-back direction. The fifth limiting surface 123 cooperates with the second connector 7 to effectively limit the movement of the second card to be fixed 4 in the front-to-back direction and prevent the second card to be fixed 4 from falling off from the second connector 7.
[0071] In one embodiment, Figure 2 , Fig.16 As shown, the first connection portion 13 is a first connection hole 131 formed on the bracket body 1 , and the first connection hole 131 is detachably connected to the main board structure 2 through the fixing member 5 .
[0072] In this embodiment, a first connection hole 131 is formed on the bracket body 10, and a detachable connection with the mainboard structure 2 can be achieved through only one fixing member 5. This installation method is simple and convenient, and it is also convenient to remove and replace the fixing card.
[0073] For example, Figure 14-16As shown, the mainboard structure 2 includes a mainboard 21, a mounting hole 211 provided on the mainboard 21, a mainboard stud 23 provided on the mainboard 21, and a spacer 22 provided on the mainboard 21. The spacer 22 is a fixing member, which is usually used to fix the interval between the mainboard and the chassis of the electronic device to ensure that the mainboard 21 does not contact the metal of the chassis. The spacer can be a patch stud (standoff). Therefore, the utility model utilizes the existing mainboard structure 2 to form a first connecting hole 131 on the bracket body 10. When it is necessary to fix the bracket 1 to the mainboard 21, the fixing member 5 is passed through the first connecting hole 131 and the mounting hole 211 on the mainboard in sequence, and then the end of the fixing member 5 is threadedly connected to the spacer 22, as shown in FIG. Fig.21 For example, the end of the fixing member 5 has an external thread, such as a screw, a bolt or a bolt.
[0074] Combination Figure 2 As shown, the first connection hole 131 is arranged near the first side of the bracket body 10, that is, the first connection hole 131 is arranged on the first opening slot side, near the main board structure 2, so as to avoid interference with the installation of other components.
[0075] For example, the first connection hole 131 and the bracket body 10 may be an integral structure. The integral part has a simple structure and has better strength than the split part. Moreover, the integral part can be injection molded by an injection molding process, which is convenient to produce.
[0076] It can also be, for example, Fig. 22 As shown, the first connection portion 13 can also be a buckle 132 formed on the bracket body 10, and the buckle 132 is used to penetrate the mounting hole 211 of the main board structure 2. The buckle 132 is configured to have a rebound force on it when it is squeezed by the mounting hole, so that the buckle 132 is fixed in the mounting hole 211. Specifically, the buckle 132 is a two-petal structure composed of a first petal 1321 and a second petal 1322. A protrusion 1323 is formed on the end surface of the first petal and the second petal along the circumferential direction of the buckle, so that the end diameter of the buckle 132 is larger than the diameter of the mounting hole 211. Therefore, the bracket 1 does not need to be connected to the spacer 22. The bracket 1 only needs to be fixed to the mounting hole 211 on the main board to achieve the installation and fixation of the bracket 1 in the mounting hole 211 on the main board 21. The bracket 1 can be fixedly connected to the mounting hole 211 of the main board through the buckle 132 thereon. It is simple and convenient, and also easy to produce. The two-piece buckle can be an integral structure with the bracket body 10, or the two-piece buckle can also be a separate piece from the bracket body, and then the two are bonded and fixed. The two-piece buckle can be made of thermoplastic elastomer or elastic plastic, so that the buckle has elasticity.
[0077] In one embodiment, Figure 2-3As shown, the second connection portion 14 includes a second connection hole 141, which is formed on the bracket body 10. The second connection hole 141 extends from the second opening groove 12 to the first opening groove 11, so that the second connection hole 141 can detachably connect the second card 4 to be fixed to the mainboard structure 2 through the fixing member 5.
[0078] In this embodiment, combined Figure 8 , Figure 17-19 As shown, since the end of the second card 4 to be fixed has a second snap-on slot 41, when the second card 4 to be fixed is accommodated in the second opening slot 12, the end of the fixing member 5 is passed through the second connecting hole 141 and the end is threadedly connected to the mainboard stud 23 on the mainboard structure 2, thereby realizing the fixation of the second card 4 to be fixed, the bracket body 10 and the mainboard structure 2, and the fixing method is simple.
[0079] Further, in this embodiment, if Figure 3 As shown, the second connecting portion 14 also includes a second protrusion 142, which is arranged on the second opening groove 12 and close to the second connecting hole 141. When the second card 4 to be fixed is accommodated on the second opening groove 12, the bottom surface of the second card 4 to be fixed is in contact with the bottom surface of the second opening groove 12, and the end surface of the second card 4 to be fixed is flush with the end surface of the second protrusion 142.
[0080] Combination Figure 8 , Fig.19 As shown, the second card to be fixed 4 has a certain thickness, so when the second card to be fixed 4 is accommodated in the second opening groove 12, the second bayonet 41 of the second card to be fixed 4 is at a certain distance from the open end of the second connection hole 141. In order to better fix the second card to be fixed 4 when the fixing member 5 is used to prevent the second card to be fixed 4 from moving, the second protrusion 142 is provided, and because the second protrusion 142 is flush with the end face of the second card to be fixed 4, it is ensured that the end face of the end of the fixing member 5 can better contact with the second card to be fixed 4 and the end face of the second protrusion 142, and the same downward pressure is exerted on the end faces of the two, further fixing the second card to be fixed 4 to prevent movement. Preferably, in order to adapt to the fixation of the fixing member 5, the second protrusion 142 is generally semicircular in shape, and is adapted to the semicircular second bayonet 41 of the second card to be fixed 4, as shown in FIG. Fig.18 shown.
[0081] Further, in this embodiment, if Figure 2 As shown, the second connection portion 14 further includes a third protrusion 143, which is formed outside the second connection hole 141 on the first opening groove side, and the third protrusion 143 is arranged along the circumferential direction of the second connection hole 141. When the bracket 1 equipped with the first to-be-fixed card 3 is connected to the main board structure 2, the end surface of the third protrusion 143 is pressed against the first end side surface of the first to-be-fixed card 3, as shown in FIG. Fig.19 shown.
[0082] Combination Fig.11 , Fig.18 , Fig.19 , Fig. 20 It can be seen that when two cards to be fixed are installed on the mainboard 21 through the bracket 1, the first end of the first card to be fixed 3 is supported on the mainboard stud 23 of the mainboard structure 2. When the fixing member 5 passes through the second connection hole 141 and is threadedly connected with the mainboard stud 23, the bracket 1 is firmly fixed on the surface of the mainboard 21. At this time, the end surface of the third protrusion 143 presses against the first end side surface of the first card to be fixed 3, exerting a downward pressing force on the first end side surface of the first card to be fixed 3, further fixing the first card to be fixed 3 in the first opening groove 11, and preventing the first card to be fixed 3 from moving.
[0083] When the bracket 1 needs to be disassembled from the main board 21, in order to prevent the main board stud 23 on the main board 21 from rotating, an anti-rotation part is also provided on the bracket body 10, specifically: Figure 2 , Figure 9-10 As shown, the second connecting portion 14 also includes an anti-rotation portion 144, which is extended from the circumference of the third protrusion 143 toward the main board structure. The anti-rotation portion 144 is a semicircular surface structure, and a plurality of teeth 1441 are provided along its semicircular direction at the connection position with the third protrusion 143. The plurality of teeth 1441 are used to cooperate with the main board stud 23 to prevent the main board stud 23 on the main board structure from rotating.
[0084] Combination Figure 9-10 It can be seen that when the bracket 1 is installed on the mainboard 21, the anti-rotation portion 144 is sleeved on the outside of the mainboard stud 23, and the teeth 1441 press against the end face of the mainboard stud 23 and exert downward pressure on the end face of the mainboard stud, preventing the mainboard stud 23 from moving with it when the fixing part 5 is removed.
[0085] Combine again Figure 2 A portion of the bottom of the anti-rotation portion 144 is connected to the side of the first connection hole 131 and the two are flush with each other, which facilitates the installation of the two connection portions and the main board structure 2.
[0086] On the other hand, the present application also provides a motherboard device, such as Figure 14-19As shown, it includes a first card to be fixed 3, a second card to be fixed 4, a first connector 6, a second connector 7 and a mainboard structure 2, the mainboard structure 2 includes a mainboard 21 and a spacer 22 and a mainboard stud 23 arranged on the mainboard 21, and a mounting hole 211 is also opened on the mainboard 21, and the mainboard 21 is also fixedly connected with the first connector 6 and the second connector 7; it also includes a bracket 1 in any one of the above embodiments; the first card to be fixed 3 is detachably mounted on the first opening groove 11, and the first connecting part 13 is detachably connected to at least one of the mounting hole 211 and the spacer 22; the second card to be fixed 4 is accommodated in the second opening groove 12 and is detachably connected to the second connecting part 14 and the mainboard stud 23 through the fixing member 5.
[0087] The first card to be fixed 3 is installed on the first opening slot 11, and the second card to be fixed 4 is accommodated in the second opening slot 12, so that the two cards to be fixed are arranged in an upper and lower position. The bracket 1 is detachably connected to at least one of the mounting hole 211 and the spacer 22 through the first connecting portion 13 and the fixing member 5, and the second card to be fixed 4 is threadedly connected to the mainboard stud 23 on the mainboard 21 through the fixing member 5. Thus, the bracket 1 and the first card to be fixed 3 and the second card to be fixed 4 installed thereon can be fixed on the mainboard 21. And the entire device only needs two fixing members, such as screws, bolts or other threaded members to fix the bracket 1, the two cards to be fixed and the mainboard structure 2. It is easy to assemble and has high assembly efficiency.
[0088] The first connection portion 13 is detachably connected to at least one of the mounting hole 211 and the spacer 22, which can be achieved by any of the following two methods:
[0089] The first type is that the first connecting portion 13 is a first connecting hole 131 formed on the bracket body 1. After the fixing member 5 passes through the first connecting hole 131 and the mounting hole 211 in sequence, the end of the fixing member 5 is threadedly connected to the spacer 22, thereby realizing a detachable connection between the first connecting hole 131 and the mainboard structure 2, and further realizing the fixing of the bracket 1 and the mainboard 21 on the spacer 22.
[0090] The second type, such as Fig. 22 As shown, the first connection portion 13 is a buckle 132 formed on the bracket body 1 , and the buckle 132 is a two-petal structure. The buckle 132 is fixed on the mounting hole 211 , thereby realizing a detachable connection between the first connection portion 13 and the mounting hole 211 .
[0091] Combination Fig.11 , Fig.12 , Fig.14After the first to-be-fixed card 3 is engaged with the first opening slot 11, the first bayonet 31 of the first end of the first to-be-fixed card 3 is supported on the mainboard stud 23, the second end of the first to-be-fixed card 3 is connected to the first connector 6, and then the fixing member 5 is passed through the first connecting hole 131 and the mounting hole 211 in sequence, and the end of the fixing member 5 is threadedly connected with the spacer 22, so that the bracket 1 is fixed on the mainboard 21. At this time, the anti-rotation portion 144 of the second connecting portion 14 on the bracket 1 is sleeved on the mainboard stud 13.
[0092] like Figure 17-19 As shown, the second end of the second to-be-fixed card 4 is connected to the second connector 7, and then the second to-be-fixed card 4 is rotated so that the first end of the second to-be-fixed card 4 is accommodated in the second opening groove 12, and after the fixing member 5 passes through the second connection hole 141, the end is threadedly connected with the mainboard stud 23, thereby fixing the second to-be-fixed card 4 on the second opening groove 12, and further fixing the bracket 1 on the mainboard 21. At this time, the third protrusion 143 has a downward pressing force on the side surface of the first end of the first to-be-fixed card 3.
[0093] For example Figure 7 As shown, when the first card to be fixed 3 is a wifi card and the second card to be fixed 4 is an SSD card, since the wifi card has an antenna, when the wifi card is fixed on the bracket 1, the bottom surface of the first opening groove 11 (i.e., the second limiting surface 112) has a downward pressing force on the antenna, thereby pressing and fixing the antenna between the wifi card body and the bracket, thereby preventing the antenna from falling off.
[0094] Below, taking the first card to be fixed 3 as a wifi card and the second card to be fixed 4 as an SSD card as an example, the assembly of the bracket 1, two cards to be fixed and the mainboard structure 2 of the present application is further described in detail in combination with the accompanying drawings.
[0095] like Figure 12-13 As shown, step 1), the first end of the wifi card is engaged in the first opening slot 11 of the bracket 1;
[0096] Step 2), connect the second end of the wifi card to the first connector 6 on the mainboard 2; Fig.14 As shown;
[0097] Step 3), rotate the bracket 1 so that the anti-rotation portion 144 of the bracket 1 is sleeved outside the motherboard stud 23, and at the same time, the first end of the wifi card is supported on the motherboard stud 23, and the first connection hole 131 is aligned with the mounting hole 211 on the motherboard 2; Fig.14 As shown;
[0098] Step 4), use a fixing member-screw to pass through the first connecting hole 131, and the end of the screw is threadedly connected with the spacer 22, so that the bracket 1 and the mainboard 2 are locked on the spacer 22; Figure 15-16As shown;
[0099] Step 5), connect the second end of the SSD card to the second connector 7; Fig.17 As shown;
[0100] Step 6), rotate the SSD card and place the first end of the SSD card in the first opening slot 11, and align the second opening of the SSD card with the second connecting hole 141; Fig.18 As shown;
[0101] Step 7), use a fixing member-screw to pass through the second connection hole 141, and the end is threadedly connected to the mainboard stud 23, so that the SSD card is fixed on the bracket 1, and then the bracket 1 is fixed on the mainboard 21; Fig.19 shown.
[0102] On the other hand, the present application also provides an electronic device, including the above-mentioned mainboard device. The electronic device with the mainboard device also has the advantages of convenient and efficient assembly of the mainboard 21 and the card to be fixed, and effectively saving space on the mainboard 21. If the first card to be fixed is a wifi card, the bracket on the mainboard can also firmly fix the antenna of the wifi card, so that the antenna will not fall off.
