[0046] First, see Figure 1 、 Figure 2 and Figure 5 One embodiment of the present application provides a limiting assembly for limiting a graphics card 100 on a motherboard 200. The graphics card 100 includes a main body 101, a connecting portion 102, and a limiting protrusion 103. The connecting portion 102 and the limiting protrusion 103 are both disposed on one end of the main body 101 near the motherboard 200. The limiting protrusion 103 is disposed on one side of the connecting portion 102 along a first direction X. The connecting portion 102 is inserted into a connection socket 201 of the motherboard 200 along a second direction Y, and the limiting protrusion 103 is located outside the connection socket 201.
[0047] The limiting assembly includes a base body 1 , a limiting rod 2 and a shifting rod 3 ; the base body 1 is fixed to the mainboard 200 and is located on one side of the connecting socket 201 along the first direction X.
[0048] The shift lever 3 is rotatably disposed in the base body 1 ; and the limiting lever 2 is rotatably disposed in the base body 1 , and the limiting lever 2 includes a limiting section 21 and a clamping section 22 that are connected to each other.
[0049] The limiting lever 2 can be switched between a limited state and a released state by rotating. When the limiting lever 2 is in the limited state, the engaging section 22 engages with the actuating lever 3, and the limiting section 21, the actuating lever 3, and the connecting socket 201 together enclose a limited space, in which the limiting protrusion 103 is retained. During the rotation of the limiting lever 2 from the limited state to the released state, the opening between the connecting socket 201 and the limiting section 21 is expanded, allowing the limiting protrusion 103 to move out of the opening.
[0050] A limit assembly provided in an embodiment of the present application switches between a limit state and a release state by rotating the limit rod 2. When the limit rod 2 is in the limit state, the engaging section 22 engages with the lever 3, and the limit section 21 and the lever 3 are arranged to form a limit space. The limit protrusion 103 is limited in the limit space, so that the graphics card 100 can be stably fixed on the motherboard 200. During the process of the limit rod 2 rotating from the limit state to the release state, the opening between the connecting socket 201 and the limit section 21 can be expanded, so that the limit protrusion 103 can be moved out of the opening, so that the graphics card 100 can be separated from the motherboard 200, thereby realizing rapid disassembly of the graphics card 100.
[0051] It should be noted that the first direction X is the X direction, the second direction Y is the Y direction, and the third direction Z is the Z direction. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.
[0052] like Figure 3 and Figure 4 As shown, in some embodiments, a locking groove 221 is provided on the locking section 22 , and a locking protrusion 31 is provided on one end of the shifting rod 3 close to the limiting rod 2 .
[0053] Continue to refer Figure 6 and Figure 7 When the limiting rod 2 is in the limiting state, the locking protrusion 31 is engaged with the locking groove 221; when the limiting rod 2 rotates from the limiting state to the released state, the locking section 22 and the shifting rod 3 can be released.
[0054] By providing a slot 221 on the engaging section 22 and providing a protrusion 31 at one end of the lever 3 close to the limiting lever 2, when the limiting lever 2 is in the limiting state, the limiting lever 2 rotates to the limiting position, and the protrusion 31 engages with the slot 221, so that the limiting section 21 and the lever 3 are relatively stably fixed, thereby making the limiting protrusion 103 stably limited in the limiting area.
[0055] In the embodiment of the present application, the latching protrusion 31 is made of elastic material.
[0056] like Figure 2 and Figure 3 As shown, in some embodiments, the limiting rod 2 further includes a guide section 23, which is fixed to one end of the clamping section 22 away from the limiting section 21, and the guide section 23 is inclined with the clamping section 22;
[0057] Continue to refer Figure 7 During the rotation of the limiting rod 2 from the limiting state to the releasing state, the locking protrusion 31 can slide along the guide section 23 to rotate the shifting rod 3 and lift the limiting protrusion 103.
[0058] By providing a guide section 23 on the limit rod 2, when the limit rod 2 rotates from the limit state to the release state, the limit rod 2 rotates, and the locking protrusion 31 can slide along the guide section 23, thereby causing the shift rod 3 to rotate, and then the shift rod 3 lifts the limit protrusion 103, making it easy to move out from the opening between the limit protrusion 103 connecting the socket 201 and the limit section 21, thereby realizing rapid disassembly of the graphics card 100.
[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the limiting rod 2 further includes a blocking section 24 , and the blocking section 24 is located at an end of the guide section 23 away from the clamping section 22 .
[0060] Continue to refer Figure 7When the limiting rod 2 is in the released state, the locking protrusion 31 abuts against the blocking section 24.
[0061] By providing a blocking section 24 at the end of the guide section 23 away from the locking section 22, the sliding range of the locking protrusion 31 can be limited to prevent the locking protrusion 31 from sliding beyond the limit rod 2, causing the shift rod 3 to disengage from the limit rod 2 and unable to rotate along with the limit rod 2, so that the shift rod 3 cannot return to the limit position and enclose together with the limit rod 2 to form a limit area to limit the limit protrusion 103, thereby causing damage to the limit assembly.
[0062] like Figure 1-Figure 3 As shown, in some embodiments, the limiting rod 2 also includes a first rotating shaft 25, which is located between the limiting section 21 and the clamping section 22. Two first rotating holes 11 are correspondingly provided on the two side walls of the base body 1 along the third direction Z. The two ends of the first rotating shaft 25 are respectively rotatably connected to the two first rotating holes 11, and the first direction X and the third direction Z are perpendicular to each other.
[0063] By setting a first rotating shaft 25 on the limiting rod 2 and correspondingly setting two first rotating holes 11 on the two side walls of the base body 1 along the third direction Z, the two ends of the first rotating shaft 25 are respectively rotatably connected to the two first rotating holes 11, so that the limiting rod 2 can rotate along the axial direction of the first rotating shaft 25.
[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the limiting assembly further includes a first elastic member 4, and a first wall 12 is provided at one end of the seat body 1 away from the connecting socket 201 along the first direction X. The first elastic member 4 is fixed in the seat body 1, and one end of the first elastic member 4 abuts against the first wall 12, and the other end of the first elastic member 4 abuts against the limiting rod 2. The first elastic member 4 has a tendency to rotate the limiting rod 2 from the limiting state to the released state.
[0065] By arranging the first elastic member 4 between the seat body 1 and the limit rod 2, the first elastic member 4 has the tendency to rotate the limit rod 2 from the limit state to the released state. On the one hand, when the graphics card 100 is fixed to the motherboard 200, the limit rod 2 is in the released state, and the limit rod 2 is tilted under the drive of the first elastic member 4. The opening of the limit protrusion 103 of the graphics card 100 entering the limit area becomes larger, so that the limit protrusion 103 of the graphics card 100 can enter the limit area more conveniently; on the other hand, when the graphics card 100 is removed from the motherboard 200, the limit protrusion 103 pushes up the limit rod 2, so that the locking protrusion 31 disengages from the locking groove 221, and the locking protrusion 31 slides along the guide section 23 to the blocking section 24. During this process, the lever 3 tilts to push up the limit protrusion 103, making it easier for the limit protrusion 103 to move out from between the connecting socket 201 and the limit section 21, further facilitating the staff to disassemble the graphics card 100.
[0066] In the embodiment of the present application, the first elastic member 4 is a torsion spring, the middle portion of which is sleeved on the first rotating shaft 25 , with one end abutting against the first wall 12 and the other end abutting against the limiting rod 2 .
[0067] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the lever 3 also includes a rod body 32 and a second rotating shaft 33, the second rotating shaft 33 is fixed to the rod body 32, and second rotating holes 13 are correspondingly provided on the two side walls of the base body 1 along the third direction Z. The two ends of the second rotating shaft 33 are respectively rotatably connected to the two second rotating holes 13, and the first direction X and the third direction Z are perpendicular to each other.
[0068] By setting a second rotating shaft 33 on the shift lever 3 and correspondingly setting two second rotating holes 13 on the two side walls of the base body 1 along the third direction Z, the two ends of the second rotating shaft 33 are respectively rotatably connected to the two second rotating holes 13, so that the shift lever 3 can rotate along the axial direction of the second rotating shaft 33.
[0069] like Figure 1 and Figure 2 As shown, in some embodiments, the limiting assembly further includes a second elastic member 5, the base body 1 is provided with a fixing seat 14 extending along the second direction Y, one end of the second elastic member 5 is fixed to the fixing seat 14, and the other end of the second elastic member 5 abuts against the end of the shift rod 3 away from the limiting rod 2, and the second elastic member 5 has a tendency to cause the shift rod 3 to lift the limiting protrusion 103, and the first direction X and the second direction Y are perpendicular to each other.
[0070] Specifically, the second rotating shaft 33 is located on one side of the rod body 32 close to the bottom of the base body 1 and in the middle of the rod body 32 . The second elastic member 5 is located at the end of the shift rod 3 away from the limiting rod 2 and abuts against the bottom of the rod body 32 .
[0071] By arranging a second elastic member 5 between the fixing seat 14 and the lever 3, the lever 3 can be driven to rotate by the second elastic member 5, so that the lever 3 is tilted to push up the limiting protrusion 103, making it easier for the limiting protrusion 103 to move out from between the connecting socket 201 and the limiting section 21, further facilitating the staff to disassemble the graphics card 100.
[0072] Second, see Figure 5 As shown, a graphics card fixing structure is also provided in an embodiment of the present application, including the above-mentioned limiting component and a graphics card 100. The graphics card 100 includes a main body 101, a connecting portion 102 and a limiting protrusion 103. The connecting portion 102 and the limiting protrusion 103 are both arranged at one end of the main body 101 close to the motherboard 200.
[0073] like Figure 6As shown, when the graphics card 100 is fixed on the motherboard 200, the connecting portion 102 of the graphics card 100 is inserted into the connecting socket 201, the locking protrusion 31 of the lever 3 is engaged in the locking groove 221 of the limiting rod 2, the limiting rod 2 and the lever 3 are enclosed to form a limiting area, and the limiting protrusion 103 of the graphics card 100 is located in the limiting area.
[0074] Specifically, such as Figure 7 As shown, during the process of disassembling the graphics card 100 from the motherboard 200, the graphics card 100 is first lifted to the side away from the motherboard 200, and the graphics card 100 pushes up the limit rod 2, so that the locking protrusion 31 of the lever 3 disengages from the locking groove 221 of the limit rod 2, and the limit rod 2 rotates under the drive of the first elastic member 4, and drives the lever 3 to rotate, and the locking protrusion 31 slides along the guide section 23 until the locking protrusion 31 abuts against the blocking section 24. During this process, the side of the lever 3 away from the limit rod 2 is lifted to the side away from the motherboard 200 under the drive of the second elastic member 5, and pushes up the limiting protrusion 103, so that the limiting protrusion 103 can be moved out from between the connecting socket 201 and the limiting section 21, thereby realizing auxiliary disassembly of the graphics card 100 and facilitating the staff to disassemble the graphics card 100.
[0075] On the third aspect, an embodiment of the present application also provides an electronic device, including the above-mentioned graphics card fixing structure, and also including a motherboard 200 and a shell, the motherboard 200 is arranged in the shell, and the graphics card fixing structure is fixedly arranged on the motherboard 200.
[0076] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0077] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
