Description

Technical Field

[0001] This application relates to the field of electronic product accessories technology, and in particular to a stretchable charging protection device. Background Technology

[0002] Traditional tablet cases mostly offer only basic protection and fail to meet users' convenience needs when charging. Users often need to carry a separate charging cable and manually insert it into the tablet's charging port. This process is not only cumbersome but also prone to damaging or losing the charging cable during charging.

[0003] In related technologies, some charging cases use built-in telescopic devices to manage the charging cable. However, these devices often employ simple mechanical structures or elastic materials, making it difficult to achieve smooth extension and retraction of the charging cable. Over long-term use, these telescopic devices are prone to losing elasticity due to wear or aging, causing the charging cable to become unstable within the case and even affecting normal charging. Furthermore, the telescopic device is prone to jamming, loosening, or detachment during the extension and retraction of the charging cable, impacting the user experience.

[0004] In summary, existing electronic device protection devices suffer from problems such as inconvenient charging and unstable charging cable retrieval, which negatively impact user experience. Utility Model Content

[0036] See Figure 1 , Figure 1 A schematic diagram of the structure of a stretchable charging protection device according to an embodiment of this application is shown. An embodiment of this application provides a stretchable charging protection device, comprising: a protective housing 10, a movable part 20, and a charging component 40. The charging component 40 is quickly exposed through the movement of the stretched part 30, facilitating charging operation.

[0037] Specifically, the protective housing 10 has an internal movable chamber 110; a movable part 20 is disposed in the movable chamber 110; a stretching part 30 is disposed on the movable part 20, and the stretching part 30 includes a charging component 40 that can be hidden inside the stretching part 30. The charging component 40 is connected to the movable part 20; when the stretching part 30 moves, it drives the movable part 20 and the charging component 40 to move, and the charging component 40 is exposed outside the protective housing 10.

[0038] In practice, the user simply holds the end of the stretching part 30 and stretches it outward. The movement of the stretching part 30 will cause the moving part 20 to move axially within the movable chamber 110. As the stretching part 30 gradually moves, the charging component 40 gradually emerges from the opening of the protective housing 10. Once the charging component 40 is fully exposed, it can be inserted into the charging port of the electronic device for charging. After charging is complete, the stretching part 30 returns to its initial position, and the charging component 40 is then hidden inside the protective housing 10. The entire device returns to a compact state, making it easy to carry and store.

[0039] In one embodiment, the protective housing 10 is made of a wear-resistant and scratch-resistant material, such as polycarbonate or aluminum alloy, to protect the internal components from external damage. The protective housing 10 has an internal movable chamber 110 that extends axially to provide space for the movable part 20 to move.

[0040] In one embodiment, the movable part 20 is disposed within the movable chamber 110 and can slide freely along the axial direction of the movable chamber 110. A lubricating layer or low-friction material may be provided between the movable part 20 and the inner wall of the movable chamber 110 to reduce resistance during movement.

[0041] In one embodiment, the stretching part 30 is connected to one end of the moving part 20. By pulling the stretching part 30, the moving part 20 is driven to move axially along the movable chamber 110, thereby pulling the charging component 40 out of the opening end of the protective housing 10 to facilitate the charging process.

[0042] In one embodiment, the charging component 40 is concealed within the stretching portion 30. The charging component 40 includes a charging interface. The main body of the charging component 40 is embedded within the stretching portion 30, while the charging interface protrudes from the stretching portion 30 and is located at the opening end of the protective housing 10, so that the charging interface is fully exposed and docked with the charging port of the electronic device as the stretching portion 30 moves.

[0043] In one embodiment, a circuit board is provided inside the protective housing 10, and the charging component 40 is connected to the circuit board.

[0044] In one embodiment, the charging component 40 is made of an elastic material, so that the charging component 40 itself has a certain elasticity, so that the charging component 40 can extend as the stretching part 30 moves, and can automatically retract after the stretching part 30 is released.

[0045] As described above, integrating the charging component 40 into the protective device reduces the inconvenience of carrying a separate charger. The charging component 40 can be quickly exposed with a simple stretching action, and remains compact when not in use. The overall structure of the device is compact, easy to operate, and convenient to carry and store. The protective housing 10 effectively prevents damage to the charging component 40 when not in use.

[0046] Combination Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a movable part 20 provided in one embodiment of this application. In some embodiments, a first mounting groove 210 is provided in the movable part 20.

[0047] Specifically, the movable part 20 has a first mounting groove 210 inside, which is used to mount and fix one end of the stretching part 30. In this embodiment, the shape and size of the first mounting groove 210 match the end of the stretching part 30, ensuring that the stretching part 30 can be firmly mounted in the movable part 20 and maintain a stable connection during stretching and contraction.

[0048] In one embodiment, the end of the stretching portion 30 near the moving portion 20 is disposed within the first mounting groove 210.

[0049] Specifically, the end of the stretching part 30 near the moving part 20 is disposed in the first mounting groove 210 of the moving part 20, and is connected to the moving part 20 by snap-fit, adhesive or other fixing methods to achieve a fixed connection between the stretching part 30 and the moving part 20.

[0050] In one embodiment, a second mounting groove 220 is provided on one side of the movable part 20 for mounting and fixing the elastic member 50. In this embodiment, the shape and size of the second mounting groove 220 match the elastic member 50 to ensure that the elastic member 50 can be securely installed in the movable part 20 and exert its elastic effect during stretching and contraction.

[0051] In one embodiment, the elastic element 50 is disposed within the second mounting groove 220 and deforms axially along the second mounting groove 220.

[0052] Specifically, the elastic element 50 is disposed within the second mounting groove 220 of the movable part 20, and can be a spring, an elastic rubber block, or other elastic components. The function of the elastic element 50 is to move axially along the second mounting groove 220 and compress and deform after the tension part 30 is stretched, and to provide a retraction force after the tension part 30 is released, enabling the tension part 30 to automatically or assistedly retract to its original position. In this embodiment, by adjusting the stiffness and preload of the elastic element 50, the retraction speed and force of the tension part 30 can be controlled, thereby improving ease of use and comfort.

[0053] Combination Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a stretchable charging protection device provided in one embodiment of this application. In some embodiments, the bottom wall of the movable chamber 110 is provided with a protrusion 120.

[0054] Specifically, a protrusion 120 is formed on the bottom wall of the movable chamber 110, and the protrusion 120 cooperates with the second mounting groove 220 of the movable part 20.

[0055] In one embodiment, the protrusion 120 is disposed within the second mounting groove 220 and has a gap with the elastic member 50.

[0056] Specifically, the protrusion 120 is disposed within the second mounting groove 220, and a gap exists between it and the elastic member 50. This gap allows the elastic member 50 a certain amount of deformation space when subjected to compression or tension, while ensuring that the moving part 20 does not generate excessive friction due to direct contact between the protrusion 120 and the elastic member 50 during sliding, thus guaranteeing smooth movement. Furthermore, the protrusion 120 can also play a certain positioning role for the moving part 20, preventing the moving part 20 from excessively sliding or dislodging within the movable chamber 110.

[0057] As described above, the gap design between the protrusion 120 and the elastic member 50, as well as the limiting effect of the protrusion 120 on the elastic member 50, improves the structural stability of the device. The limiting effect of the protrusion 120 on the elastic member 50 prevents excessive deformation or dislodgement of the elastic member 50, thus extending the service life of the device.

[0058] Combination Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the stretching part 30 provided in one embodiment of this application. In some embodiments, the moving part 20 includes a slider 230, which is disposed in the movable chamber 110 and slides in cooperation with the side wall of the movable chamber 110.

[0059] Specifically, the sidewalls of the movable chamber 110 are smooth to ensure that the slider 230 can slide smoothly. The moving part 20 includes a slider 230, which is disposed within the movable chamber 110 and fits tightly against the sidewalls of the movable chamber 110 to achieve a sliding connection. In this embodiment, the shape of the slider 230 is adapted to the shape of the movable chamber 110 and can be a rectangular structure to ensure stable sliding performance.

[0060] In one embodiment, the first mounting groove 210 is a T-shaped groove formed in the slider 230; the end of the stretching part 30 near the moving part 20 is a T-shaped structure.

[0061] Specifically, a first mounting groove 210 is provided within the slider 230. The first mounting groove 210 is a T-shaped groove for mounting the tensioning part 30. The end of the tensioning part 30 closest to the moving part 20 is configured with a T-shaped structure, which matches the first mounting groove 210, ensuring that the tensioning part 30 can be securely mounted on the moving part 20 and move together with the moving part 20, thus improving the stability of the connection. Simultaneously, using a T-shaped structure embedded in the T-shaped groove for connection facilitates subsequent disassembly or maintenance / replacement. In this embodiment, the first mounting groove 210 can be located in the middle region of the slider 230.

[0062] In one embodiment, the second mounting groove 220 is a strip-shaped groove, and the protrusion 120 is a protrusion. The elastic element 50 is a spring, one end of which abuts against the inner wall of the second mounting groove 220, and the other end has a gap with the protrusion.

[0063] Specifically, a second mounting groove 220 with a strip-shaped structure is provided on one side of the slider 230 for mounting the elastic element 50. The elastic element 50 is specifically in the form of a spring. One end of the spring abuts against the inner wall of the second mounting groove 220, and the other end of the spring has a gap with the protrusion 120 in the movable chamber 110, so that the spring can provide a certain resistance or restoring force when the moving part 20 moves. When the tension part 30 is stretched, the moving part 20 moves accordingly, and the spring is compressed; when the tension part 30 is released, the elastic force of the spring pushes the moving part 20 to return to its original position.

[0064] In one embodiment, the protrusion 120 is a bump formed by the outward protrusion of the bottom wall of the movable chamber 110, used to limit the compression range of the elastic member 50 and provide it with support. Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the protective housing 10 provided in one embodiment of this application. In some embodiments, it further includes a limiting part 60, which is formed in the side wall of the movable chamber 110 and protrudes toward the moving part 20.

[0065] Specifically, a limiting part 60 is provided on the side wall of the movable chamber 110, and the limiting part 60 protrudes toward the movable part 20. The shape and size of the limiting part 60 match the limiting groove 240, and when the movable part 20 is installed in the movable chamber 110, the limiting part 60 can partially extend into the limiting groove 240.

[0066] In one embodiment, a limiting groove 240 is provided on one side of the moving part 20, the limiting groove 240 extends along the axial direction of the moving part 20, and the limiting part 60 is disposed in the limiting groove 240.

[0067] Specifically, the limiting groove 240 is formed on the side wall of the moving part 20 near the limiting part 60. The limiting groove 240 extends along the axial direction of the moving part 20, so that the limiting part 60 can provide stable guidance and limiting function during the movement of the moving part 20, and prevent the moving part 20 from rotating or shaking during the stretching and resetting process.

[0068] In the specific implementation process, when the stretching part 30 is stretched, the moving part 20 moves axially along the movable chamber 110. At this time, the limiting part 60 slides within the limiting groove 240, providing stable guidance for the moving part 20. Since the limiting groove 240 extends axially along the moving part 20, the limiting part 60 can ensure that the moving part 20 maintains linear motion during movement, avoiding deviation or swaying.

[0069] When the tensioning part 30 is released, the moving part 20 drives the tensioning part 30 to reset under the action of the elastic member 50. At this time, the limiting part 60 continues to slide within the limiting groove 240, providing stable guidance and limiting for the reset of the moving part 20.

[0070] Combination Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a stretchable charging protection device provided in one embodiment of this application. In some embodiments, it further includes an extension 70, which protrudes from one side of the movable part 20.

[0071] Specifically, the extension 70 protrudes from one side of the moving part 20 to form a plate-like structure. The main function of the extension 70 is to provide a winding point, allowing the charging component 40 to rotate around it and extend into the stretching part 30. The surface of the extension 70 that contacts the charging component 40 can be provided with a smooth or grooved structure to reduce friction and wear of the charging component 40 during the winding process.

[0072] In one embodiment, the charging component 40 is wound around the extension 70, with one end of the charging component 40 disposed on the bottom wall of the movable chamber 110, and the other end of the charging component 40 passing through the first mounting groove 210 and extending into the stretching portion 30 and exposed at the opening end of the protective housing 10. In this embodiment, one end of the charging component 40 can be connected to the bottom wall by welding, plugging, or other fixing methods.

[0073] In the specific implementation process, when the user needs to charge, they only need to pull the stretching part 30, which drives the moving part 20 to expose the charging component 40 outside the protective housing 10 for charging. After charging is completed, the stretching part 30 is released, and under the action of the elastic member 50, the moving part 20 drives the stretching part 30 and the charging component 40 to reset, and the charging component 40 is retracted into the protective housing 10.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
