Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a fastener, a connection structure, and an electronic device. Background Art
[0002] With the rapid development of laptop computers, the design of laptop computers is becoming more and more user-friendly and convenient. The C shell in a laptop computer refers to the shell around the laptop keyboard and touchpad, and the D shell refers to the lower shell of the laptop that contacts the desktop. The C shell and the D shell are usually connected by anti-stripping screws to prevent the C shell from separating from the D shell. In order to respond to customers' needs for convenient disassembly, especially when customers replace the solid-state drive (Solid State Disk or Solid State Drive, referred to as SSD) or add a wireless network card by themselves, removing the D shell is undoubtedly the first problem encountered. When the D shell is difficult to disassemble, it greatly affects the customer experience.
[0003] The existing method for disassembling the shell is to first remove all the external screws on the D shell, and then pry the C shell to disengage the hooks of the D shell. However, this method is likely to cause damage to the shell, especially the rubberized area on the shell. Utility Model Content
[0004] The present disclosure provides a fastener, a connection structure, and an electronic device to at least solve the above technical problems existing in the prior art.
[0005] According to a first aspect of the present disclosure, a fastener is provided, comprising: a smooth rod portion, a threaded portion, and a limiting portion arranged between the smooth rod portion and the threaded portion, wherein a clamping portion for clamping a retaining spring is formed between the smooth rod portion and the limiting portion, and the diameter of the limiting portion is larger than the diameter of the clamping portion; wherein the diameter of the clamping portion is configured to be compatible with the nominal inner diameter of the retaining spring.
[0006] In one embodiment, the outer periphery of the limiting portion is a smooth surface.
[0007] In one embodiment, the diameter of the limiting portion is larger than the major diameter of the threaded portion.
[0008] In one embodiment, a cap body is further included. The cap body is connected to an end of the polished rod portion away from the clamping portion, and a groove is formed on the cap body.
[0009] According to a second aspect of the present disclosure, a connection structure is provided, including a first body, a second body and a retaining spring, wherein the first body and the second body are connected by the fastener described in any one of the above-mentioned embodiments, and the retaining spring is engaged with the retaining portion.
[0010] In one embodiment, the first body is provided with a through hole for the fastener to pass through, the second body is provided with a threaded hole, and an accommodating space for accommodating the retaining spring is provided between the first body and the second body.
[0011] In one embodiment, the first body and the second body have a connected state and a separated state. When the first body and the second body are in the connected state, the fastener is passed through the through hole, and the threaded portion is engaged with the threaded hole; when the first body and the second body are switched from the connected state to the separated state, the threaded portion is unscrewed from the threaded hole, and the limiting portion is subjected to force so that the retaining spring presses against the first body, thereby separating the first body from the second body.
[0012] In one embodiment, the second body further has a retreat groove communicated with the threaded hole, and when the first body and the second body are in a connected state, the limiting portion is located in the retreat groove.
[0013] In one embodiment, the height of the accommodating space is not less than the thickness of the clamping spring.
[0014] According to a third aspect of the present disclosure, an electronic device is provided, comprising the connection structure as described in the above possible embodiments.
[0015] In the present disclosure, since the fastener has a limiting portion, a holding portion for holding the retaining spring is formed between the smooth rod portion and the limiting portion, and the limiting portion can limit the retaining spring on the holding portion to prevent the retaining spring from falling into the position of the threaded portion; when the fastener is disassembled, the threaded portion is unscrewed, and the limiting portion is subjected to force to make the retaining spring press against one of the parts to be disassembled, and the force of the retaining spring on one of the parts to be disassembled facilitates its disassembly and separation from the other part to be disassembled.
[0016] It should be understood that the contents described in this section are not intended to identify the key or important features of the embodiments of the present disclosure, nor are they intended to limit the scope of the present disclosure.

[0024] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.
[0025] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
[0026] Reference Figure 1 and Figure 2 As shown, a fastener according to an exemplary embodiment of the present disclosure includes a polished rod 1, a threaded portion 2, and a stopper 3 disposed between the polished rod 1 and the threaded portion 2. A retaining portion 4 for retaining a retaining spring 5 is formed between the polished rod 1 and the stopper 3. The diameter of the retaining portion 3 is larger than that of the retaining portion 4. The diameter of the retaining portion 4 is configured to match the nominal inner diameter of the retaining spring 5.
[0027] In this embodiment, the fastener is used to lock the housing of the device. At the same time, the fastener also has the function of making the housing easy to disassemble. Therefore, the housing is one of the parts to be disassembled. When disassembly is required, the housing needs to be removed from the other part to be disassembled. The bare rod portion 1 of the fastener has no threads and is responsible for bearing the tension, shear force and torsion force in the connection. Its load-bearing function ensures the firmness of the connection structure. The surface of the threaded portion 2 has screw threads, which are used to lock one of the parts to be disassembled with the other of the parts to be disassembled. There are many types of retaining springs 5, including retaining springs for shafts, retaining springs for holes, C-type retaining springs, U-type retaining springs and E-type retaining springs. In this disclosure, the E-type retaining spring is preferably used. The E-type retaining spring has an "E"-shaped structure with arms extending outward on both sides and an open part in the middle. The overall design is compact and stable. The E-type retaining spring is clamped into the holding portion 4 through its elastic deformation, thereby providing a stable axial fixing force to ensure the firmness and stability of the overall structure. By limiting the diameter of the limiting portion 3 to be larger than the diameter of the holding portion 4 , the clamping spring 5 is prevented from sliding into the position of the threaded portion 2 .
[0028] In summary, since the fastener has a limiting portion 3, a holding portion 4 for holding the retaining spring 5 is formed between the light rod portion 1 and the limiting portion 3, and the limiting portion 3 can limit the retaining spring 5 on the holding portion 4 to prevent the retaining spring 5 from falling into the position of the threaded portion 2; when the fastener is disassembled, the threaded portion 2 is unscrewed, and the limiting portion 3 is subjected to force to make the retaining spring 5 press against one of the parts to be disassembled, and the force of the retaining spring 5 on one of the parts to be disassembled facilitates its disassembly and separation from the other part to be disassembled.
[0029] In one embodiment, the outer periphery of the limiting portion 3 is a smooth surface.
[0030] In this embodiment, the outer peripheral surface of the limiting portion 3 is smooth and has no threads, which can support the retaining spring 5 and prevent the retaining spring 5 from falling into the threaded portion 2. When the fastener is unscrewed, the limiting portion 3 can push the retaining spring 5 against the part to be removed, thereby assisting in disassembly.
[0031] In one embodiment, the diameter of the limiting portion 3 is larger than the major diameter of the threaded portion 2 .
[0032] In one embodiment, the fastener further includes a cap body 6 , which is connected to an end of the polished rod portion 1 away from the clamping portion 4 , and a groove is formed on the cap body 6 .
[0033] In this embodiment, the cap 6 has various shapes and types, including but not limited to hexagonal, round, countersunk, or pan heads. The groove on the cap 6 allows a screwdriver to rotate and lock the fastener. By rotating the cap 6, the fastener can be tightened to the desired degree. The cap 6 acts as a receiving point for the rotational force, transmitting the rotational force applied by the screwdriver to the polished shaft 1 and the threaded portion 2 to produce a tightening effect.
[0034] Reference Figure 2As shown, the present disclosure also provides a connection structure, including a first body 7, a second body 8 and a retaining spring 5. The first body 7 and the second body 8 are connected by a fastener in any one of the above-mentioned embodiments, and the retaining spring 5 is engaged with the retaining portion 4.
[0035] In this embodiment, the connection structure is typically provided on the housing of an electronic device. For example, in a laptop computer, the first body 7 represents the D-shell of the laptop, and the second body 8 represents the C-shell of the laptop. The retaining spring 5 is preferably an E-shaped retaining spring. The E-shaped retaining spring has an "E" shape, with outwardly extending arms on either side and an opening in the middle, resulting in a compact and stable overall design. The E-shaped retaining spring elastically deforms to engage the retaining portion 4, providing a stable axial securing force and ensuring the overall structural strength and stability. By limiting the diameter of the retaining portion 3 to be larger than that of the retaining portion 4, the retaining spring 5 is prevented from slipping into the threaded portion 2. Since the connecting structure includes a fastener, the fastener has a limiting portion 3, and a holding portion 4 for holding the retaining spring 5 is formed between the light rod portion 1 and the limiting portion 3. The limiting portion 3 can limit the retaining spring 5 on the holding portion 4 to prevent the retaining spring 5 from falling into the position of the threaded portion 2; when the fastener is disassembled, the threaded portion 2 is unscrewed, and the limiting portion 3 is subjected to force to make the retaining spring 5 press against the first body 7. The force of the retaining spring 5 on the first body 7 facilitates its disassembly and separation from the second body 8.
[0036] In one embodiment, the first body 7 is provided with a through hole 71 for the fastener to pass through, the second body 8 is provided with a threaded hole 81 , and an accommodating space for accommodating the retaining ring 5 is provided between the first body 7 and the second body 8 .
[0037] Specifically, refer to Figure 3 and Figure 4 As shown, in one embodiment, the first body 7 and the second body 8 have a connected state and a separated state. When the first body 7 and the second body 8 are in the connected state, the fastener is passed through the through hole 71, and the threaded portion 2 is engaged with the threaded hole 81; when the first body 7 and the second body 8 are converted from the connected state to the separated state, the threaded portion 2 is unscrewed from the threaded hole 81, and the limiting portion 3 is subjected to force so that the retaining spring 5 presses against the first body 7, so that the first body 7 and the second body 8 are separated.
[0038] In this embodiment, the fastener is used in conjunction with an E-shaped retaining spring to push out the first body 7, making it easier to disassemble the device. In actual operation, the fastener is first inserted through the through-hole 71 of the first body 7. The E-shaped retaining spring is then installed on the side of the first body 7 near the second body 8. The fastener is then tightened normally. When the fastener is loosened during disassembly, the fastener's retaining portion 3 drives the E-shaped retaining spring upward, along with the first body 7, during the loosening process. As the fastener is continuously unscrewed, the height of the first body 7 increases, resulting in a larger gap between the first body 7 and the second body 8, making disassembly easier for the user.
[0039] In one embodiment, the second body 8 further has a retreat groove 82 communicating with the threaded hole 81 . When the first body 7 and the second body 8 are in a connected state, the limiting portion 3 is located in the retreat groove 82 .
[0040] In one embodiment, the height of the accommodating space is not less than the thickness of the clamping spring 5 .
[0041] The present disclosure also provides an electronic device, comprising a connection structure as in any one of the above-mentioned embodiments.
[0042] In this embodiment, the electronic device may include, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a smartwatch, etc. Since the electronic device includes a connection structure, the fastener in the connection structure has a limiting portion 3. A retaining portion 4 for retaining a retaining spring 5 is formed between the smooth rod portion 1 and the limiting portion 3. The limiting portion 3 can retain the retaining spring 5 on the retaining portion 4 to prevent the retaining spring 5 from falling into the position of the threaded portion 2. When the fastener is disassembled, the threaded portion 2 is unscrewed, and the limiting portion 3 is subjected to force, causing the retaining spring 5 to press against the first body 7. The force exerted by the retaining spring 5 on the first body 7 facilitates its removal from the second body 8.
[0043] In the description of the present disclosure, it should be understood that the orientation or positional relationship indicated by the directional words is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present disclosure and simplifying the description.
