Abstract
Description
Technical Field
[0001] This application relates to the field of notebook computer technology, and in particular to an RJ45 cover structure and a notebook computer. Background Technology
[0002] As people's living standards continue to improve, laptops are gradually becoming a common tool in households, used for daily work and leisure. To reduce the weight and size of laptops for portability, the requirements for their thickness are increasing, making thinner and lighter designs a key trend in laptop development.
[0003] Current laptops, including their bottom cases, typically use a direct-plug method for connecting network cables, with the cable plugged into the bottom case. The thickness of a laptop is limited by the size of the RJ45 network cable port on the side wall. To accommodate this port, the bottom case usually has a one-piece protrusion for mounting the RJ45 port. This protrusion makes the laptop thicker, preventing it from being made thinner and limiting the overall thickness to below 18mm. This fails to meet the trend towards thinner and lighter laptops and also affects the overall aesthetics, thus requiring improvement. Utility Model Content
[0004] In order to reduce the thickness of laptops and improve portability, this application provides an RJ45 cover structure.
[0005] Firstly, the RJ45 cover structure provided in this application adopts the following technical solution:
[0006] An RJ45 cover structure includes a base, a cover, a crystal head, and a clamping member. A network interface is provided on one side of the bottom of the base for the crystal head to be inserted. The cover is disposed inside the network interface and is used to clamp the inserted crystal head. The clamping member is disposed on the base and connected to the cover, and is used to control the cover to press firmly against the crystal head.
[0007] By adopting the above technical solution, the base is recessed for installation, further reducing the thickness of the laptop. The cover is a rotatable flip design. When the RJ45 connector is inserted into the network interface, the cover is closed by a clamping device, securing the RJ45 connector clip. The thickness of the laptop's CD section (the distance between the C and D shells) can be reduced to 11.3mm, and the overall thickness can be reduced to within 15.8mm, a 12.2% reduction compared to traditional solutions.
[0008] Preferably, it further includes a fixed bracket and a connecting rod, the clamping element is a torsion spring, the fixed bracket is disposed on the base and close to the network interface, the connecting rod is horizontally disposed and rotatably connected to the fixed bracket, the torsion spring passes through the connecting rod and is used to control the resetting of the connecting rod; the cover is connected to the connecting rod and uses the connecting rod as a pivot.
[0009] By adopting the above technical solution, when the crystal head is inserted into the network interface, the cover is subjected to a squeezing force, which causes the connecting rod to rotate synchronously. At this time, the torsion spring deforms and generates elastic potential energy, which hinders the rotation of the cover, thereby achieving the clamping of the crystal head by the cover and improving the stability of the crystal head installation.
[0010] Preferably, the fixing bracket is detachably connected to the base body, and the fixing bracket has a plurality of mounting holes for fasteners to pass through.
[0011] By adopting the above technical solution, the fastener passes through the mounting hole and is then locked onto the base. The fastener is a detachable object such as a bolt or screw, enabling a detachable connection between the fixed bracket and the base.
[0012] Preferably, the fixed bracket has a groove, a protrusion is connected in the groove, the torsion spring forms a U-shaped cavity, the protrusion is located in the U-shaped cavity and is used to limit the torsion spring.
[0013] By adopting the above technical solution, the protrusion is set in the U-shaped cavity of the torsion spring. When the connecting rod drives the torsion spring to rotate, the torsion spring can abut against the groove of the fixed bracket. At the same time, the protrusion plays a limiting role for the torsion spring, restricting the displacement of the torsion spring and improving the stability of the torsion spring position.
[0014] Preferably, the fixed bracket is further provided with a limiting groove, and a limiting block is integrally connected to the cover. When the cover and the connecting rod rotate, the limiting block is always located in the limiting groove.
[0015] By adopting the above technical solution, when the cover and the connecting rod rotate synchronously, the limiting block is always in the limiting groove. The limiting groove can make way for the rotation of the limiting block, but will not allow the limiting block to fall out of the limiting groove, thereby improving the stability of the cover installed on the fixed bracket.
[0016] Preferably, when the crystal head is plugged into the network interface, a locking block is provided on the side of the cover facing the crystal head, and the locking block is used to limit the locking plate of the crystal head.
[0017] By adopting the above technical solution, when the RJ45 connector is plugged into the network interface, the locking contacts will be blocked by the locking block. The locking block and the locking contacts on the RJ45 connector cooperate with each other to prevent the RJ45 connector from coming out of the network interface, thereby improving the stability of the RJ45 connector installation.
[0018] Preferably, the clamping element is a magnet, the cover is rotatably connected to the fixed bracket via the connecting rod, and the magnet is disposed on the fixed bracket and is used to attract the cover.
[0019] By adopting the above technical solution, a magnet is used instead of a torsion spring. When the cover is closed, the crystal head is fixed by magnetic attraction. The cover is made of a metal material that can be attracted by a magnet. The magnetic attraction method has the advantages of no mechanical fatigue and a longer lifespan.
[0020] Secondly, this application also provides a notebook computer that includes all of the aforementioned RJ45 cover structures.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] (1) By setting up a base, cover and clamping parts, the base and cover are designed separately, breaking through the thickness limitation of the traditional integrated structure; the torsion spring clamping and rotation limit work together to achieve reliable self-locking of the crystal head, solving the industry pain point that ultra-thin equipment cannot integrate RJ45 interface.
[0023] (2) By setting grooves and protrusions on the fixed bracket, when the connecting rod drives the torsion spring to rotate, the torsion spring can abut against the groove of the fixed bracket. At the same time, the protrusions limit the displacement of the torsion spring and improve the stability of the position of the torsion spring.
[0024] (3) By setting a locking block, when the crystal head is plugged into the network interface, the locking plate will be blocked by the locking block, which restricts the crystal head from coming out of the network interface and improves the stability of the crystal head installation.

[0030] The technical solutions of this application will now be described with reference to the accompanying drawings of the embodiments.

[0033] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.
[0035] This application discloses an RJ45 cover structure. (Refer to...) Figures 1 to 3The RJ45 cover structure includes a base 1, a cover 2, an RJ45 connector 3, and a clamping component 4. A network interface 5 is located on one side of the bottom of the base 1, for the RJ45 connector 3 to be inserted. The cover 2 is rotatably connected to the base 1, positioned near the network interface 5, and is used to clamp the inserted RJ45 connector 3. The cover 2 rotates as the RJ45 connector 3 is inserted into the network interface 5. The clamping component 4 is mounted on the base 1 and connected to the cover 2; the clamping component 4 controls the cover 2 to clamp the RJ45 connector 3.
[0036] Specifically, in this embodiment, the clamping element 4 is a torsion spring. A fixed bracket 6 and a connecting rod 7 are also installed on the base 1. The fixed bracket 6 is close to the network interface 5, and the connecting rod 7 is horizontally positioned and rotatably connected to the fixed bracket 6, with its own length serving as a pivot. The torsion spring passes through the connecting rod 7 and is used to control the resetting of the connecting rod 7. When the connecting rod 7 rotates, the torsion spring deforms and generates elastic potential energy. The cover 2 is connected to the connecting rod 7, and the cover 2 and the connecting rod 7 rotate coaxially.
[0037] When the RJ45 connector 3 is inserted into the network interface 5, the cover 2 is subjected to pressure, causing the connecting rod 7 to rotate synchronously. At this time, the torsion spring deforms and generates elastic potential energy, resisting the rotation of the cover 2 and thus pressing the cover 2 firmly against the RJ45 connector 3, improving the stability of the RJ45 connector 3 installation. By separating the base 1 and the cover 2, the thickness limitation of the traditional integrated structure is broken, further reducing the thickness of the laptop. The thickness of the CD section of the laptop (referring to the distance between the C shell and the D shell) can be reduced to 11.3mm, and the overall thickness can be reduced to within 15.8mm, a reduction of 12.2% compared to traditional solutions.
[0038] The fixed bracket 6 is detachably connected to the base 1. The fixed bracket 6 has several mounting holes 8 for fasteners to pass through. The fasteners are bolts or screws, which pass through the mounting holes 8 and lock the fixed bracket 6 to the base 1. The detachable connection between the fixed bracket 6 and the base 1 is achieved by screwing. The fixed bracket 6 has a rectangular groove 11, within which a protrusion 12 is fixedly connected. The torsion spring has a U-shaped cavity, and the protrusion 12 is located within the U-shaped cavity, serving to limit the torsion spring's lateral movement on the connecting rod 7. When the connecting rod 7 rotates the torsion spring, the torsion spring abuts against the groove 11 of the fixed bracket 6, and the protrusion 12 also limits the torsion spring's displacement, improving its positional stability.
[0039] The fixed bracket 6 also has two limiting grooves 9, which are arranged opposite each other. The cover 2 is integrally connected with the same number of limiting blocks 10, each corresponding to one of the two limiting grooves 9. The size of the limiting block 10 is smaller than the space of the limiting groove 9, allowing the limiting groove 9 to accommodate the rotation of the limiting block 10 without causing it to disengage. When the cover 2 and the connecting rod 7 rotate, the limiting block 10 remains within the limiting groove 9. The limiting block 10 and the limiting groove 9 cooperate to improve the stability of the cover 2 mounted on the fixed bracket 6.
[0040] Combination Figure 4 In this embodiment, a locking block 13 is also fixedly connected to the side of the cover 2 facing the crystal head 3. When the crystal head 3 is plugged into the network interface 5, the locking block 13 is used to limit the locking piece on the crystal head 3. The locking piece is blocked by the locking block 13. The locking block 13 and the locking piece on the crystal head 3 cooperate with each other to prevent the crystal head 3 from detaching from the network interface 5, thereby improving the stability of the crystal head 3 installation.
[0041] Furthermore, according to some embodiments of this application, optionally, the clamping element 4 is a magnet, and the cover 2 is still rotatably connected to the fixed bracket 6 via the connecting rod 7. The magnet is fixedly installed on the fixed bracket 6 and located below the cover 2, and is used to attract the cover 2. The attraction force of the magnet on the cover 2 is used to limit the rotation of the cover 2. The cover 2 is made of a material that can be attracted by a magnet, such as magnetic plastic, metal, and alloy. In this embodiment, a magnet is used instead of a torsion spring. When the cover 2 is closed, the crystal head 3 is fixed by magnetic attraction. The cover 2 is made of a metal material that can be attracted by a magnet. The magnetic attraction method has the advantages of no mechanical fatigue and longer service life.
[0042] The implementation principle of the RJ45 cover structure in this application embodiment is as follows: When the crystal head 3 is inserted into the network interface 5, the cover 2 is subjected to a squeezing force, which drives the connecting rod 7 to rotate synchronously. At this time, the torsion spring deforms and generates elastic potential energy, which hinders the rotation of the cover 2, thereby achieving the clamping of the crystal head 3 by the cover 2. The separate design of the base 1 and the cover 2 breaks through the thickness limitation of the traditional integrated structure; the torsion spring clamping and rotation limit work together to achieve reliable self-locking of the crystal head 3, solving the industry pain point that ultra-thin devices cannot integrate RJ45 interfaces.
[0043] Based on the above embodiments, this application also provides a laptop computer, which includes an RJ45 cover structure with all the above-described structures. Since the RJ45 cover structure has been discussed above, it will not be repeated here.
[0044] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
