Technical Field
[0001] This application relates to the field of fastening installation structure technology, and in particular to a fastening structure, motherboard and electronic product. Background Technology
[0002] Some circuit boards in electronic products, such as printed circuit boards, solid-state drives, or wireless communication modules, are typically fastened with screws or plastic parts, requiring the use of a screwdriver to assemble the screws. During assembly, there is a risk that the screwdriver may come into contact with or collide with other components, causing damage. Screws may also fall out and puncture the battery. There are also defects such as lost screws and plastic parts not being grounded together with the circuit board.
[0003] To address the aforementioned issues, the screws can be attached to the plastic parts to prevent them from falling out and puncturing the battery. However, this method still requires a screwdriver, and the risk of the screwdriver touching or colliding with other components cannot be eliminated. Furthermore, it is inconvenient to operate in some space-constrained locations, increases the skill requirements for operators, and requires the removal of both the screws and plastic parts when replacing circuit boards, which can easily lead to the loss of parts and increased costs. Summary of the Invention
[0004] To address at least the above-mentioned technical problems existing in the prior art, this application provides a fastening structure, a motherboard, and an electronic product.
[0005] This application provides a fastening structure, including a support base, a limiting member, and a telescopic member. The support base has a receiving cavity, and the outer wall of the support base has a telescopic opening communicating with the receiving cavity. The telescopic opening is at a set height from the bottom of the support base. The first end of the limiting member passes through the telescopic opening into the receiving cavity, and the first end of the limiting member is connected to the inner wall of the receiving cavity through the telescopic member. The second end of the limiting member is used to switch between a first position and a second position. When the limiting member compresses the telescopic member, causing the limiting member to retract into the receiving cavity, the second end of the limiting member is located in the first position. When the telescopic member drives the second end of the limiting member to extend out of the telescopic opening, the second end of the limiting member is located in the second position. The extended portion of the limiting member is used to limit the components connected to the fastening structure along the height direction of the support base.
[0006] In some embodiments, a limiting protrusion is further provided on the outer wall of the support base, and the limiting protrusion is arranged radially along the support base; when the second end of the limiting member is in the second position, the limiting protrusion and the protruding portion of the limiting member form a clamping and limiting effect on the element connected to the fastening structure.
[0007] In some embodiments, the support base is columnar, the limiting protrusion is annular and sleeved on the outer wall of the support base, and the surface of the limiting protrusion is perpendicular to the axis of the support base.
[0008] In some embodiments, the limiting member further includes a toggle member disposed on the outer wall of the limiting member; the toggle member drives the second end of the limiting member to switch from a second position to a first position.
[0009] In some embodiments, the support base further includes a toggle port located at the top of the support base and communicating with the receiving cavity; the toggle member has a set length, and one end of the toggle member away from the limiting member extends through the toggle port, the toggle member being used to move within the toggle port, causing the second end of the limiting member to switch from a second position to a first position.
[0010] In some embodiments, the end of the limiting member away from the bottom of the support base is provided with an arc-shaped guide surface; the arc-shaped guide surface is used to be squeezed by the element connected to the fastening structure, thereby driving the second end of the limiting member to switch from the second position to the first position.
[0011] In some embodiments, the telescopic member includes a spring, one end of which is connected to a first end of the limiting member, and the other end of which is connected to the inner wall of the receiving cavity.
[0012] In some embodiments, the axis of the spring is perpendicular to the axis of the support.
[0013] This application also provides a motherboard including the aforementioned fastening structure.
[0014] In another aspect, this application also provides an electronic product, including the above-described fastening structure or including the above-described motherboard.
[0015] This application provides a fastening structure, motherboard, and electronic product. In use, a support base is mounted on the mounting position. When a limiting member is subjected to force, its second end moves to the first position. At this time, the limiting member retracts into the receiving cavity, allowing the connected component to be installed. The side end of the component abuts against the side wall of the support base. After the force on the limiting member disappears, when the second end of the limiting member is in the second position, a portion of the limiting member extends out, and this extended portion limits the connected component below it. This technical solution eliminates the need for screws or other components during installation, making the limiting and fastening operation of the connected components simpler and faster, shortening production line assembly time. Furthermore, the installation method is simple and easy to operate, requiring less skill from operators and resulting in a low defect rate. Attached Figure Description

[0027] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] This application provides a fastening structure, including a support base, a limiting member, and a telescopic member. The support base serves to support and limit the connected component, and supports the limiting member and the telescopic member. The limiting member cooperates with the telescopic member to switch the position of the limiting member. When the second end of the telescopic member moves to the second position, it can fasten and limit the connected component.
[0029] The following description, in conjunction with the accompanying drawings, details the various structures of the fastening structure provided in the embodiments of this application, the positional relationships between the structures, and the connection relationships.
[0030] like Figure 1 and Figure 2 As shown in the embodiment of this application, the support base 10 is provided with a receiving cavity 11, and the outer wall of the support base 10 is provided with a telescopic opening 12 communicating with the receiving cavity 11. The telescopic opening 12 is at a set height from the bottom of the support base 10. The first end 21 of the limiting member 20 passes through the telescopic opening 12 into the receiving cavity 11, and the first end 21 of the limiting member 20 is connected to the inner wall of the receiving cavity 11 through the telescopic member 30. The second end 22 of the limiting member 20 is used to switch between a first position and a second position.
[0031] The fastening structure limits the connected component 40 via the limiting member 20. For example, in electronic products, the fastening structure is used to limit the connection of the connected component 40, which is a removable component such as a solid-state disk (SSD). By switching the position of the second end 22 of the limiting member 20, the fastening and limiting of the connected component 40 can be achieved or the fastening and limiting can be released.
[0032] Specifically, in this embodiment, when the limiting member 20 compresses the telescopic member 30 and the limiting member 20 retracts into the receiving cavity 11, there is no limiting structure on the outer wall of the support base 10, and the connected component 40 can be installed normally. The side end of the connected component 40 is provided with a bayonet, which can be fastened to the outer wall of the support base 10. The second end 22 of the limiting member 20 is located in the first position. When the telescopic member 30 drives the second end 22 of the limiting member 20 to extend out of the telescopic opening 12, the second end 22 of the limiting member 20 is located in the second position, and the extended part of the limiting member 20 is used to limit the fastening structure connected component 40 along the height direction of the support base 10.
[0033] like Figure 3 As shown in the embodiment of this application, a limiting protrusion 13 is also provided on the outer wall of the support base 10, and the limiting protrusion 13 is arranged radially along the support base 10; when the second end 22 of the limiting member 20 is in the second position, the limiting protrusion 13 and the protruding part of the limiting member 20 form a clamping limit on the element 40 connected to the fastening structure.
[0034] For example, when the support base 10 is installed on the motherboard, a groove corresponding to the limiting protrusion 13 is provided on the motherboard, and the limiting protrusion 13 is engaged in the groove.
[0035] For example, the support base 10 is columnar, and the limiting protrusion 13 is annular and sleeved on the outer wall of the support base 10. The surface of the limiting protrusion 13 is perpendicular to the axis of the support base 10. The limiting protrusion 13 forms a horizontal support plane, and the bottom surface of the second position of the limiting member 20 is parallel to the limiting protrusion 13, thereby forming a stable clamping structure.
[0036] like Figure 4 As shown in the embodiment of this application, the limiting member 20 further includes a toggle member 23, which is disposed on the outer wall of the limiting member 20; the toggle member 23 drives the second end 22 of the limiting member 20 to switch from the second position to the first position.
[0037] When it is necessary to release the fastening limit on the connected component 40, the force can be applied to the limiting member 20 by the actuating member 23, thereby completing the position switching of the second end 22 of the limiting member 20. For example, continue to refer to Figure 3 As shown, the support base 10 also includes a toggle port 14, which is located at the top of the support base 10 and communicates with the receiving cavity 11; the toggle member 23 has a set length, and one end of the toggle member 23 away from the limiting member 20 extends out of the toggle port 14. The toggle member 23 is used to move within the toggle port 14, so that the second end 22 of the limiting member 20 switches from the second position to the first position.
[0038] After the support base 10 is installed, the toggle operation is completed at its top, making it convenient to operate. For example, a semi-circular notch structure can also be provided at the end of the toggle port 14, with the top of the toggle member 23 flush with the top of the toggle port 14, and the toggle operation of the toggle member 23 is completed at the notch structure position.
[0039] Continue to refer to Figure 4 As shown in the embodiment of this application, the end of the limiting member 20 away from the bottom of the support base 10 is provided with an arc-shaped guide surface 24; the arc-shaped guide surface 24 is used to be squeezed by the component 40 connected to the fastening structure, thereby driving the second end 22 of the limiting member 20 to switch from the second position to the first position.
[0040] After the fastening structure is installed, in the unused state, the second end 22 of the limiting member 20 is located in the second position. The limiting member 20 can be squeezed by the connected element 40, and the second end 22 of the limiting member 20 is squeezed to the first position, so that the connected element 40 can be installed smoothly. This operation does not require any tossing operation, making the installation simpler and faster.
[0041] In this embodiment, the telescopic member 30 includes a spring. One end of the spring is connected to the first end 21 of the limiting member 20, and the other end is connected to the inner wall of the receiving cavity 11. The spring is a compression spring structure. In its natural state, the spring drives the second end 22 of the limiting member 20 to the second position. When the limiting member 20 is subjected to force, the limiting member 20 applies pressure to the spring, causing the spring to be in a contracted state. When the force of the limiting member 20 disappears, the limiting member 20 returns to its original position under the action of the spring's restoring force.
[0042] like Figure 2 As shown in this embodiment, the axis of the spring is perpendicular to the axis of the support base 10. The force exerted by the spring on the limiting member 20 is also perpendicular to the axis of the support base 10, allowing the limiting member 20 to reciprocate along this vertical direction.
[0043] For example, a slot is provided on the inner wall of the support base 10, one end of the spring is engaged in the slot, and a protrusion is provided on the side wall of the limiting member 20 on the same side as the spring, and the other end of the spring is sleeved on the protrusion, thereby achieving stable installation of the spring.
[0044] This application provides a motherboard including the aforementioned fastening structure. This application also provides an electronic product including the aforementioned fastening structure or including the aforementioned motherboard. The motherboard is provided with... Figures 1 to 4 The fastening structure shown allows for simple and quick assembly and disassembly of some components on the motherboard.
[0045] Taking SSD installation as an example, mounting holes are provided on the motherboard, and the support bracket 10 is installed in the mounting holes. One end of the SSD is connected to the connector, and the other end is connected to the fastening structure. When connected to the fastening structure, pressing the SSD causes the SSD's board end to apply force to the limiting member 20, causing the second end 22 of the limiting member 20 to switch from the second position to the first position. The SSD's board end passes over the limiting member 20. After the force applied by the SSD disappears, the limiting member 20 automatically resets, thereby achieving the limiting of the SSD's board end. Figure 5 As shown.
[0046] During disassembly, the staff manually moves the toggle 23, which in turn switches the second end 22 of the limit member 20 from the second position to the first position. After the limit member 20 is released, the SSD can be separated from the fastening structure.
[0047] This application provides a fastening structure, motherboard, and electronic product. In use, a support base 10 is mounted on the mounting position. When the limiting member 20 is subjected to force, its second end 22 moves to the first position. At this time, the limiting member 20 retracts into the receiving cavity 11, allowing the connected component 40 to be installed. The side end of the component abuts against the side wall of the support base 10. After the force on the limiting member 20 disappears, when the second end 22 of the limiting member 20 is in the second position, a portion of the limiting member 20 extends out, and this extended portion limits the connected component 40 below it. This technical solution eliminates the need for screws or other components during installation, making the limiting and fastening operation of the connected component 40 simpler and faster, shortening production line assembly time. Furthermore, the installation method is simple and easy to operate, requiring less skill from operators and resulting in a low defect rate.
