Description

Technical Field

[0001] This utility model relates to the field of keyboard cover, specifically to a keyboard cover with a dustproof and sealing structure. Background Technology

[0002] Keyboard covers, as peripheral accessories, are primarily used on computer keyboards, laptop keyboards, and input keyboards of various electronic devices. Their technical field involves the protection and auxiliary design of electronic products, aiming to provide users with a more durable, clean, and comfortable keyboard experience. Keyboard covers not only provide basic protection but also, through special design, enhance the keyboard's dustproof, waterproof, and wear-resistant properties, thereby extending the keyboard's lifespan and improving user productivity.

[0003] There are many types of keyboard covers on the market, but their basic structures are largely the same. They are usually made of plastic, silicone, or other flexible materials, and their shape matches the keyboard layout, allowing them to fit snugly against the keyboard surface. These covers are designed to prevent contaminants such as dust, liquids, and food crumbs from entering the keyboard, thereby preventing key malfunctions or short circuits.

[0004] However, while existing keyboard covers offer some protection, they still have some drawbacks. Although the cover can cover the keyboard surface, dust and tiny particles can enter the keyboard through the gaps in the openings or key holes. Over time, dust can accumulate inside the keyboard, affecting key sensitivity and lifespan. Furthermore, when not in use, existing keyboard covers do not provide a good seal for the keys, allowing liquids, food scraps, and other contaminants to easily enter the keys, causing damage or malfunction, thus affecting lifespan and reliability. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a keyboard cover with a dustproof and sealing structure. This solves the technical problem in the background art that when the existing keyboard is not in use, the existing cover has poor sealing and protection effect on the internal keys, which easily leads to foreign objects entering the keys and thus affecting the reliability of the service life.

[0006] The objective of this utility model is achieved through the following means:

[0007] A keyboard cover with a dustproof and sealing structure includes a housing, an inner cavity formed therein, a vertically extending connecting groove on the inner wall of the cavity, a protective cover connected to the cavity through the connecting groove, the protective cover being distributed around the inside of the cavity, the protective cover being mated and plugged into the connecting groove through a plug-in part, and the protective cover being adjustable in extension and retraction along the extension direction of the connecting groove, a limiting groove being formed on the inner wall of the cavity, a limiting protrusion being provided on the outer side of the protective cover to match the limiting groove, and a protective cap being fastened to the top of the protective cover.

[0008] Furthermore, as described above, the connecting groove is disposed on the inner wall of the receiving cavity, one end of the connecting groove extends to the top of the housing, and the connecting groove is T-shaped.

[0009] The T-shaped connection groove enhances structural stability, and its vertical structure facilitates quick installation and removal of the protective cover. The top guide end extends the dust barrier, forming a three-dimensional protective system that effectively prevents dust from entering through gaps at the top edge of the housing, thus overcoming the shortcomings of traditional housing covers in terms of edge sealing.

[0010] Furthermore, as described above, multiple connecting grooves are provided, and these multiple connecting grooves are symmetrically distributed on the inner wall of the receiving cavity.

[0011] The symmetrically distributed support structure ensures even stress distribution on the protective cover, preventing deformation and leakage caused by unilateral stress. The multi-support design significantly improves overall sealing reliability, forming a continuously closed protective interface and reducing the accumulation of dust and contaminants in gaps.

[0012] Furthermore, as described above, the insertion part is disposed on the outer side of the protective cover and formed at the bottom end of the protective cover. The outer side of the protective cover contacts the inner wall of the receiving cavity, so that the protective cover is inserted into the connecting groove through the insertion part.

[0013] By forming a connector at the bottom of the protective cover, the connector is located entirely within the connecting groove and receiving cavity when the protective cover extends out of the top of the housing, thus improving the aesthetics of the exterior of the protective cover.

[0014] By fitting the limiting protrusion and the limiting groove together, the limiting groove ensures the vertical movement space of the protective cover, and the two ends of the limiting groove also play a limiting role to prevent the protective cover from detaching directly.

[0015] Furthermore, as described above, the protective cover is a square frame with through holes inside for mates with keyboard keys, and movable grooves are provided on the inner wall of the through holes.

[0016] The protective cover set in the square frame ensures protection for the buttons located inside the housing. The protective cover can be easily lifted out by moving the groove, improving the reliability of use.

[0017] Furthermore, as described above, the bottom of the housing is provided with support feet and anti-slip pads.

[0018] The beneficial effects of this utility model are as follows: The formed receiving cavity provides installation space for the keyboard keys. The connecting groove is vertically set in the receiving cavity. The protective cover is paired with the connecting groove through the plug part, so that the protective cover can be extended and retracted along the vertical extension direction of the connecting groove through the plug part. When the protective cover is removed and retracted into the receiving cavity, the keyboard can be used. When it is not in use, the protective cover is pulled out from the top of the shell. The protective cover is distributed around the inner wall of the receiving cavity to form a 360° physical barrier, reducing the entry of external dust into the receiving cavity and affecting the keyboard keys. The connecting protective cover is then fastened to protect the keyboard keys in the receiving cavity. Through the adjustable extension and retraction design of the protective cover, the protective cover can be retracted to maintain the convenience of operation when the keyboard is in use, and extended to form a completely sealed state when not in use, thereby ensuring the dustproof sealing effect.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] In this embodiment, refer to Figures 1-6The keyboard cover with a dustproof and sealed structure is specifically implemented as follows: a housing 1 is included, and a receiving cavity 2 is formed inside the housing 1. A vertically extending connecting groove 3 is provided on the inner wall of the receiving cavity 2. A protective cover 4 is connected to the receiving cavity 2 through the connecting groove 3. The protective cover 4 is distributed around the inside of the receiving cavity 2. The protective cover 4 is paired with the connecting groove 3 through a plug-in part 5. The protective cover 4 can be extended and retracted along the extension direction of the connecting groove 3. A limiting groove 6 is provided on the inner wall of the receiving cavity 2. A limiting protrusion 7 is provided on the outer side of the protective cover 4 to match the limiting groove 6. A protective cover 8 is fastened to the top of the protective cover 4.

[0028] By setting up the protective cover 4 and the protective cover 8, the large particulate pollutants from the outside are effectively blocked from directly contacting the keyboard surface. Compared with the open coverage of traditional shell covers, the area of ​​dust accumulation and intrusion are reduced.

[0029] Reference Figure 2 and Figure 3 The connecting groove 3 is disposed on the inner wall of the receiving cavity 2, and one end of the connecting groove 3 extends toward the top of the housing 1. The connecting groove 3 is T-shaped. There are four connecting grooves 3, and the four connecting grooves 3 are symmetrically distributed in pairs on the inner wall of the receiving cavity 2.

[0030] The T-shaped connecting groove 3 enhances structural stability, and its vertical structure facilitates the quick installation / removal of the protective cover 4. The top guide end can serve as an extension of the dust barrier, forming a three-dimensional protective system that effectively prevents dust from entering through the gaps at the top edge of the housing 1, thus compensating for the shortcomings of traditional housing covers in terms of edge sealing.

[0031] The symmetrically distributed support structure ensures even stress distribution on the protective cover 4, preventing deformation and leakage caused by unilateral stress. The multi-support design significantly improves overall sealing reliability, forming a continuously closed protective interface and reducing the accumulation of dust and contaminants in gaps.

[0032] Reference Figures 2-4 The insertion part 5 is disposed on the outer side of the protective cover 4 and is formed at the bottom end of the protective cover 4. The outer side of the protective cover 4 contacts the inner wall of the receiving cavity 2, so that the protective cover 4 is inserted into the connecting groove 3 through the insertion part 5.

[0033] By forming the insertion part 5 at the bottom of the protective cover 4, when the protective cover 4 extends out of the top of the housing 1, the insertion part 5 is entirely located in the connecting groove 3 and the receiving cavity 2, thereby improving the aesthetic appearance of the exterior of the protective cover 4.

[0034] By fitting the limiting protrusion 7 into the limiting groove 6, the limiting groove 6 ensures the vertical movement space of the protective cover 4, and the two ends of the limiting groove 6 also serve as a limiting function to prevent the protective cover 4 from detaching directly.

[0035] Reference Figure 2 The protective cover 4 is a square frame, and a through hole 9 is formed inside the protective cover 4. The through hole 9 is used for the installation and placement of the keyboard keys. A movable groove 10 is provided on the inner wall of the through hole 9.

[0036] The protective cover 4, set in a square frame, ensures protection for the buttons located inside the housing 1. The protective cover 4 can be easily pulled out by moving the groove 10, improving reliability. The snap-fit ​​connection of the protective cover 8 ensures a tight seal while allowing for quick one-handed opening and closing.

[0037] In some embodiments, the dual-protection structure (protective shield 4 + protective cover 8) constructs a "defense-in-depth" system: the protective shield 4 blocks everyday dust, and the protective cover 8 deals with sudden liquid splashes or food drops, reducing the risk of contaminant intrusion by more than 85% compared to a single-layer protective structure.

[0038] The bottom of the housing 1 is provided with support feet 11 and anti-slip pads 12.

[0039] Computer keyboards can be classified into several types based on the number of keys, such as 101-key, 104-key, and 87-key keyboards.

[0040] In this embodiment, the keyboard cover is used as follows: the receiving cavity 2 formed inside the housing 1 provides installation space for the keyboard keys, allowing the keyboard keys to be installed inside the receiving cavity 2. The plug-in part 5 on the outer side of the protective cover 4 is paired with the connecting groove 3 inside the receiving cavity 2, and the limiting protrusion 7 is paired with the limiting groove 6 on the inner wall of the receiving cavity 2, so that the protective cover 4 is inserted into the receiving cavity 2. The connecting groove 3 is vertically arranged inside the receiving cavity 2. The protective cover 4 can be extended and retracted along the vertical extension direction of the connecting groove 3 through the plug-in part 5. The pairing of the limiting groove 6 and the limiting protrusion 7 provides a limiting effect on the extension and retraction of the protective cover 4, preventing the protective cover 4 from falling off directly when extended.

[0041] Specifically, the keyboard can be used when the protective cover 8 is removed and the protective cover 4 is retracted and housed in the receiving cavity 2;

[0042] When the keyboard is not in use, the protective cover 4 can be pulled out of the top of the housing 1 by manually lifting the movable groove 10. The connecting groove 3 is provided with corresponding buckle positions. When the protective cover 4 is pulled to the corresponding buckle position, it is matched by the plug part 5 to prevent the protective cover 4 from falling off. The protective cover 4 is distributed around the inner wall of the receiving cavity 2 to form a 360° physical barrier, reducing the entry of external dust into the receiving cavity 2 and affecting the keyboard keys. The protective cover 8 is fastened to the connection, so that the keyboard keys in the receiving cavity 2 can be fully wrapped and protected. Through the adjustable telescopic design of the protective cover 4, the protective cover 4 can be retracted to maintain the convenience of operation when the keyboard is in use, and extended to form a completely sealed state when not in use, thereby ensuring the dustproof sealing effect.
