Description

Technical Field

[0001] This disclosure relates to the field of screw fastening technology, and in particular to an anti-loosening mechanism, a motherboard module, and electronic equipment. Background Technology

[0002] Currently, in order to save space on the motherboard, the heatsink module is fastened to the CPU bracket by heatsink screws, thus securing the heatsink module to the CPU. However, when removing the heatsink module, the heatsink screws need to be tightened back. The force of tightening the heatsink screws will also cause the screws on the CPU bracket to rotate, causing the screws on the CPU bracket to loosen or be pulled out, thus posing a safety risk to the CPU.

[0003] To address the aforementioned issues, the current solution involves making the screws on the CPU into D-shaped screws, and correspondingly, making the holes on the CPU backplate D-shaped holes to prevent the screws from rotating. However, because the screws are D-shaped and cannot rotate, this solution increases the difficulty of installation and tightening, significantly lengthening the time spent placing and tightening the screws, thus impacting production efficiency. For the same production needs, more manpower is required for tightening, and the tightening process involves repeatedly flipping the fixture used for assembling the motherboard, which also poses a certain risk to the quality of the motherboard. Utility Model Content

[0004] This disclosure provides an anti-detachment mechanism, a motherboard module, and an electronic device to at least solve the above-mentioned technical problems existing in the prior art.

[0005] According to a first aspect of this disclosure, an anti-hair loss mechanism is provided, comprising:

[0006] The body has at least one hollow mounting post, and the mounting post has a through hole that penetrates the inner and outer walls of the mounting post.

[0007] Fastener, having a threaded structure, the threaded structure being threadedly connected to the mounting post; and

[0008] The elastic element includes a connecting end and a spring arm. The connecting end is fixedly connected to the outer wall, and the spring arm extends into the through hole and abuts against the threaded structure to prevent the fastener from rotating and disengaging from the body.

[0009] In one embodiment, the elastic element is C-shaped and sleeved around the outer periphery of the mounting post. The elastic element includes a C-shaped segment, the connecting end is located on the C-shaped segment, and the elastic arm is formed at the end of the C-shaped segment.

[0010] In one embodiment, the spring arm is bent toward the mounting post, and the free end of the spring arm abuts against the threaded structure.

[0011] In one embodiment, the threaded structure is a left-hand thread or a right-hand thread, and the extension direction of the spring arm is configured to be the same as the direction of rotation of the threaded structure to prevent the threaded structure from rotating as the fastener moves in the direction of loosening the fastener.

[0012] In one embodiment, the elastic element further includes a pressing arm extending from the end of the C-shaped segment, the pressing arm forming an angle with the elastic arm.

[0013] In one embodiment, the fastener further includes a connecting structure having internal threads for connecting other cylindrical connectors.

[0014] According to a second aspect of this disclosure, a motherboard module is provided, including a motherboard and an anti-detachment mechanism as described in any of the above embodiments for mounting the motherboard, wherein the fastener passes through the motherboard and is securely connected to the body.

[0015] According to a third aspect of this disclosure, an electronic device is provided, including a heat dissipation assembly and a motherboard module as described in the above-described embodiments, wherein the heat dissipation assembly is securely connected to the motherboard module.

[0016] In one embodiment, the heat dissipation assembly includes a heat dissipation module and a locking member disposed on the heat dissipation module, the locking member being locked to the fastener.

[0017] This disclosure also provides an electronic device including an anti-detachment mechanism as described in the above-described embodiments.

[0018] In this disclosure, an elastic element is added to the mounting post of the anti-detachment mechanism body, and a through hole is made in the mounting post penetrating the inner and outer walls of the mounting post. This allows the elastic arm of the elastic element to pass through the through hole and abut against the threaded structure of the fastener. This ensures that when the fastener is subjected to force and tends to detach from the body, the elastic arm can abut against the threaded structure of the fastener, preventing the fastener from unscrewing. Because the elastic element is elastic, an external force can also be applied to the elastic element to disengage the elastic arm from the through hole, allowing the fastener to be loosened normally. Therefore, during assembly, only the normal tightening of the fastener is required for installation. After installation, the elastic arm of the elastic element abuts against the threaded structure, achieving self-locking. The structure is simple and the operation is quick, requiring no additional operations. This reduces the quality and damage risks caused by complex assembly operations, saves manpower, and improves assembly efficiency.

[0029] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0030] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1 , Figure 2 and Figure 3As shown, this disclosure discloses an exemplary embodiment of an anti-detachment mechanism, including a body 1, a fastener 2, and an elastic element 3. The body 1 has at least one hollow mounting post 11, with a through hole 12 penetrating both the inner and outer walls of the mounting post 11. The fastener 2 has a threaded structure 21, which is threadedly connected to the mounting post 11. The elastic element 3 includes a connecting end 311 and a spring arm 32. The connecting end 311 is fixedly connected to the outer wall of the mounting post 11, and the spring arm 32 extends into the through hole 12 and abuts against the threaded structure 21 to prevent the fastener 2 from rotating and detaching from the body 1.

[0032] In this embodiment, the body 1 is used to assemble other electronic components. For example, in a laptop computer, the body 1 can assemble electronic components including but not limited to a CPU. The position of the mounting post 11 on the body 1 corresponds to the position of the fastener 2. The mounting post 11 is hollow, and the fastener 2 passes through the mounting post 11 and is fastened to the mounting post 11. Specifically, the fastener 2 has a threaded structure 21, and the inner wall of the hollow mounting post 11 has internal threads. The fastener 2 is screwed to the mounting post 11. The connecting end 311 of the elastic member 3 is fixedly connected to the outer wall of the mounting post 11, preferably by welding. The mounting post 11 has a through hole 12 that penetrates the inner and outer walls of the mounting post 11. The elastic arm 32 of the elastic member 3 extends through the through hole 12 and abuts against the threaded structure 21 of the fastener 2, so that the fastener 2 can only rotate in the direction of tightening the fastener 2, and cannot rotate in the direction of loosening the fastener 2, preventing the fastener 2 from rotating away from the body 1.

[0033] In summary, by adding an elastic element 3 to the mounting post 11 of the anti-detachment mechanism body 1, and by creating a through hole 12 penetrating the inner and outer walls of the mounting post 11, the elastic arm 32 of the elastic element 3 can pass through the through hole 12 and abut against the threaded structure 21 of the fastener 2. This ensures that when the fastener 2 tends to detach from the body 1 under force, the elastic arm 32 can abut against the threaded structure 21 of the fastener 2, preventing the fastener 2 from unscrewing. Because the elastic element 3 is elastic, external force can also be applied to the elastic element 3 to disengage the elastic arm 32 from the through hole 12, allowing the fastener 2 to be loosened normally. Therefore, during assembly, only the fastener 2 needs to be tightened normally for installation. After installation, the elastic arm 32 of the elastic element 3 abuts against the threaded structure 21, achieving self-locking. The structure is simple and the operation is quick, requiring no additional operations. This reduces the quality and damage risks caused by complex assembly operations, saves manpower, and improves assembly efficiency.

[0034] In one embodiment, the elastic member 3 is C-shaped and sleeved around the outer periphery of the mounting post 11. The elastic member 3 includes a C-shaped segment 31, the connecting end 311 of the elastic member 3 is located on the C-shaped segment 31, and the elastic arm 32 is formed at the end of the C-shaped segment 31.

[0035] In this embodiment, the spring arm 32 is formed at the end of the C-shaped segment 31. Specifically, the spring arm 32 extends from the end of the C-shaped segment 31 and extends toward the mounting post 11; or, the outline of the spring arm 32 is cut or stamped at the position near the end of the C-shaped segment 31, and then the spring arm 32 is bent toward the mounting post 11 to form a spring arm 32 that can abut against the threaded structure 21 of the fastener 2.

[0036] In one embodiment, the spring arm 32 bends toward the mounting post 11, and the free end of the spring arm 32 abuts against the threaded structure 21.

[0037] In one embodiment, the threaded structure 21 is a left-hand thread or a right-hand thread, and the extension direction of the spring arm 32 is configured to be the same as the direction of rotation of the threaded structure 21, so as to prevent the threaded structure 21 from rotating with the fastener 2 in the direction of loosening the fastener 2.

[0038] In this embodiment, the principle of the elastic element 3 preventing the fastener 2 from falling off is as follows: when the fastener 2 tends to fall off relative to the body 1, the elastic arm 32 is interfered with and squeezed. Due to its elasticity, the elastic arm 32 pushes the fastener 2 tightly in the opposite direction, thus preventing the fastener 2 from falling off. Therefore, the specific position of the connection end 311 of the elastic element 3 in the anti-fall mechanism connected to the mounting post 11 needs to be adaptively designed according to the locking direction of the fastener 2. That is, it needs to ensure that the elastic arm 32 can allow the fastener 2 to rotate in the direction of tightening the mounting post 11, while blocking the thread structure 21 of the fastener 2 from rotating in the direction of loosening. Specifically, when the thread structure 21 is a left-hand thread, and the fastener 2 is screwed into the mounting post 11 counterclockwise, the extension direction of the spring arm 32 is also counterclockwise when viewed from the direction in which the fastener 2 is screwed into the mounting post 11; that is, the spring arm 32 bends counterclockwise. When the thread structure 21 is a right-hand thread, and the fastener 2 is screwed into the mounting post 11 clockwise, the extension direction of the spring arm 32 is also clockwise when viewed from the direction in which the fastener 2 is screwed into the mounting post 11; that is, the spring arm 32 bends clockwise. With this design, even if the fastener 2 is connected to other structures, and the loosening of other structures causes the fastener 2 to have a tendency to move, the fastener 2 will not be driven to rotate and loosen.

[0039] Reference Figure 2 and Figure 3 As shown, in one embodiment, the elastic member 3 further includes a pressing arm 33, which extends from the end of the C-shaped segment 31, and forms an angle between the pressing arm 33 and the elastic arm 32.

[0040] In this embodiment, when it is necessary to disassemble the fastener 2, the user only needs to press the pressing arm 33 to disengage the spring arm 32 from the threaded structure 21 to loosen the fastener 2 and remove it. To facilitate loosening the fastener 2, the spring arm 32 is usually disengaged from the through hole 12 by pressing, so that the spring arm 32 is stuck on the outer wall of the mounting post 11 to prevent the spring arm 32 from springing back and re-aggregating with the threaded structure 21 of the fastener 2.

[0041] Reference Figure 4 As shown, in one embodiment, the fastener 2 further includes a connecting structure 22 having internal threads for connecting other cylindrical connectors.

[0042] In this embodiment, the fastener 2 includes a nut, which can be a regular nut or a nut with a connecting structure 22, allowing the nut to connect to other structural components simultaneously. The nut with the connecting structure 22 is cylindrical and has features including, but not limited to, countersunk holes or threaded countersunk holes, for connection to other cylindrical structural components. Taking a laptop computer as an example, the connecting structure 22 of the fastener 2 of the anti-detachment mechanism can be connected to the screws of the heat dissipation module, fixing the heat dissipation module to the body 1. Simultaneously, the fastener 2 on the body 1 can be used to fix the CPU. Thus, the heat dissipation module is connected to the CPU, providing more efficient heat dissipation for the CPU and saving assembly space, supporting miniaturization and thinner design of electronic devices.

[0043] Reference Figure 5 As shown, this disclosure also provides a motherboard module, including a motherboard and an anti-detachment mechanism as described in any of the above embodiments for assembling the motherboard, wherein a fastener 2 passes through the motherboard and is fastened to the body 1.

[0044] Reference Figure 6 As shown, this disclosure also provides an electronic device, including a heat dissipation component 5, and a motherboard module as described in the above-described embodiments, wherein the heat dissipation component 5 is securely connected to the motherboard module.

[0045] Specifically, in one embodiment, the heat dissipation component 5 includes a heat dissipation module 51 and a locking member 52 disposed on the heat dissipation module 51, the locking member 52 being locked to the fastener 2.

[0046] In this embodiment, the electronic device can be a device with a heat dissipation component 5, including but not limited to laptops, all-in-one computers, etc. By providing an anti-dislodgement mechanism in the electronic device, when the heat dissipation component 5 needs to be disassembled, as the locking member 52 is loosened, the spring arm 32 of the elastic member 3 can abut against the threaded structure 21 of the fastener 2, preventing the fastener 2 from being unscrewed and preventing damage to the motherboard.

[0047] This disclosure also provides an electronic device including an anti-detachment mechanism as described in the above-described embodiments.
