Description

[0001] Title of the invention: Magnetic Winder

[0002] Technical field:

[0003] The present invention relates to the field of electronic device charging systems. More specifically, it applies to charging cable winding mechanisms.

[0004] State of the art:

[0005] In the electronic device charging solutions sector, the rapid evolution of technologies and the increasing diversity of devices used daily have highlighted the need to adapt and optimize charging systems. Current devices, while effective in specific contexts, often encounter limitations in terms of flexibility and adaptability to changing user needs. The multitude of charger types and the requirement to be tied to fixed charging points represent significant obstacles to a seamless and uninterrupted user experience.

[0006] The Spanish document ES1228175U, published on April 11, 2019, by Arquero Santos Santiago Ignacio and Arquero Santos Federico Agustin, proposes a common base for wall-mounted electrical mechanisms, incorporating elements such as retractable cables and USB sockets. While relevant for certain applications, this solution does not directly address the issue of modularity or the possibility of easily interchanging charging elements to meet specific user needs. Furthermore, the absence of magnetic connections in this document highlights a significant opportunity for improvement in terms of ease of use and connection efficiency.

[0007] Objective of the invention:

[0008] Thus, the objective of the envisaged invention is to overcome these challenges by introducing an innovative solution that integrates both modularity, through the use of modular cartridges, and improved connectivity, thanks to the adoption of magnetic connections. This approach aims not only to offer an optimized user experience, but also to address the shortcomings identified in existing solutions, such as those described in ESI 228175U.

[0009] The other objects, features, and advantages of the present invention will be more clearly understood through a detailed examination of the following description. It is anticipated that this invention will bring about significant improvements in terms of efficiency, flexibility, and user experience in the field of charging devices for electronic devices, thus providing a concrete response to current and future user needs.

[0010] General summary of the invention:

[0011] To achieve this objective, according to one embodiment, a charging device is provided comprising a cable configured to allow the electrical charging of an electronic device, the device comprising a reel configured to allow the cable to be wound so as to selectively allow the device to pass from a retracted configuration in which at least a portion of the cable is wound around the reel to an extended configuration in which at least a portion of the cable is extracted from the reel, the device comprising an electrical connection system at a second end of the cable, suitable for being connected to the external electrical network so as to supply electrical current to the cable, the electrical connection system is a pin electrical connector which includes a magnetic element configured so as to facilitate maintaining the connection of the charging device to the electrical network.

[0012] Without the present invention, users of electronic device charging systems would often face problems with usability and durability. Traditional charging systems frequently require manual adjustments to maintain a stable connection and are prone to damage to both connectors and cables due to repeated handling and pulling. Furthermore, cable management can become cumbersome, with an increased risk of tangling and damage over time, thus reducing charging efficiency and convenience.

[0013] This would lead to premature equipment degradation, increasing costs for users who frequently need to replace their charging cables. Furthermore, loose or poorly established connections could compromise device charging, resulting in charging interruptions and significant user frustration. The lack of a compact and easy-to-use solution exacerbates these problems, making daily charging of electronic devices more cumbersome and less reliable.

[0014] Thus, the present invention overcomes these challenges by offering an innovative charging device that combines efficiency, compactness, and durability. Thanks to its intelligent winding system and magnetic electrical connector, it ensures easy installation and a secure electrical connection.

[0015] This approach minimizes the risk of damage to the cable and connectors, thus extending the device's lifespan and providing an improved user experience. By reducing the need for direct handling and eliminating common problems associated with traditional connections, this invention represents a significant advancement in the field of charging devices for electronic devices, facilitating everyday charging while ensuring a stable and reliable connection.

[0016] Detailed description of the implementation methods:

[0017] Another aspect concerns a system comprising a mounting device and a charging device.

[0018] According to one embodiment, the invention comprises a method for connecting a charging device comprising a cable configured to allow the electrical charging of an electronic device, the device comprising a reel configured to allow the cable to be wound so as to selectively allow the device to pass from a retracted configuration in which at least a portion of the cable is wound around the reel to an extended configuration in which at least a portion of the cable is extracted from the reel, the device comprising an electrical connection system at a second end of the cable, suitable for being connected to the external electrical network so as to supply electrical current to the cable, the electrical connection system being a pin-type electrical connector which includes a magnetic element configured to facilitate maintaining the connection of the charging device to the electrical network.The process includes a step of positioning and connecting the system to the electrical network using at least one magnetic element. As an example, the reel has dimensions such that it can be contained within an enclosure 100 mm high, 100 mm deep, and 20 mm wide.

[0019] This allows for adaptation to numerous environments and usage scenarios, minimizing bulk and promoting portability. Indeed, by ensuring that the reel is within specific, reduced dimensions, the device is compact, practical, and discreet, easily stored or transported while still offering an efficient winding mechanism.

[0020] In one example, the charging cable has a USB Type-C connector at one end of the cable and a pogo pin electrical connector at the other end of the cable.

[0021] This allows for broad compatibility of the charging device with a wide range of electronic devices, combining the universality of USB Type-C with the specificity of the pogo pin connector. Advantageously, it can also accommodate other types of connectors. Indeed, market demand requires versatility in charging adapters for electronic devices, meeting the needs of both devices with standard interfaces and those requiring a specific connection solution.

[0022] According to one example, the magnetic element comprises a plurality of magnets, preferably two magnets, preferably distributed symmetrically around a first electrical connector.

[0023] This ensures a strong and reliable connection thanks to the symmetrically distributed magnetic force, guaranteeing that the device remains securely in place when plugged in. Indeed, by using multiple magnets, particularly two magnets symmetrically arranged around the electrical connector, the connection benefits from a balanced magnetic force, reducing the risk of accidental disconnection and increasing the product's lifespan.

[0024] According to one example, the charging device includes a winding spring configured to allow the cable to be retracted by winding around the reel in a main winding direction X33, from the deployed configuration to the retracted configuration.

[0025] This allows for automatic and even cable winding, facilitating storage and preventing potential damage from improper winding. By incorporating a winding spring, the device ensures the cable returns uniformly around the reel. This automation guarantees hassle-free use and extends the cable's lifespan by preventing excessive twisting and kinking.

[0026] According to one example, the system includes a mounting device and the charging device according to the present invention, the mounting device being configured to hold in position and secure the charging device.

[0027] The mounting module is advantageously housed in a single unit. The modularity of the mount and the adaptability of the cable reel make this device particularly useful in various environments, whether for wall mounting or as part of a multi-platform charging station. Furthermore, the winding mechanism and magnetic system ensure smooth and intuitive operation for the end user.

[0028] In one example, the support module is configured to adapt modularly to a wall-mounted device.

[0029] Preferably, the bracket is configured to be fixed in a wall niche. Fixing can be achieved by clipping and / or screwing and / or gluing and / or any other type of mechanical fixing known to those skilled in the art.

[0030] As an example, the recessed mounting system is configured to adapt modularly to a remote charging device. This could be a remote charging station and / or a power strip.

[0031] Preferably, the system configured in this way allows for modular replacement of the different types of sockets in case of failure.

[0032] According to one example, the fixing of the charging device to the recessed device is carried out at least partially by means of a tongue / groove cooperation, the groove extending in a direction orthogonal to a winding direction X33 of the charging cable.

[0033] It is specified that, within the framework of the present invention, the terms "on," "overcomes," "covers," "underlying," "opposite," and their equivalents do not necessarily mean "in direct contact with." These terms describe the spatial relationship between different components of the charging device, where elements may be positioned next to or above one another without necessarily being in physical contact. In the following description, unless otherwise indicated, when reference is made to absolute positional qualifiers, such as "front," "back," "top," "bottom," "left," "right," etc., or relative positional qualifiers, such as "above," "below," "superior," "inferior," etc., or to orientational qualifiers, such as "horizontal," "vertical," "lateral," etc., reference is made to the orientation of the charging device in its typical operating condition, as envisioned by the designer.

[0034] An element located "perpendicular" or "directly above" another element means that these two elements are aligned in a vertical or horizontal direction, taking into account the standard orientation of the charging device during use. This precision helps in understanding the internal arrangement of the components and their interaction.

[0035] The terms "approximately," "about," and "in the order of" indicate an approximation that is acceptable within the technical context of the charging device. When dealing with measurable data, this may indicate a variation of plus or minus 10%.

[0036] These terms allow for minor variations in dimensions, proportions, or angles that do not significantly alter the functionality of the device.

[0037] In the following description, the term "on" does not necessarily mean "directly on". This allows us to understand that the assembly or interaction between two components of the charging device may involve interfaces or intermediaries, without affecting the overall functionality of the system.

[0038] In this patent application, the designation of two parts as distinct emphasizes their functional or structural independence within the charging device. This distinction is important for understanding the modularity and adaptability of the proposed device.

[0039] A single, one-piece unit within the charging device highlights the integrated design of certain elements, which, although indivisible, can interact with other modular components to form a complete and functional charging system.

[0041] [Fig. 2] Figure 2 represents a perspective view of the same example device as in Figure 1, this one being positioned in a wall-mounted fixture.

[0042] [Fig. 3] Figure 3 represents a cross-sectional view along a plane orthogonal to the direction of cable winding; in this representation, the wall-mounting device is positioned in a recess in a wall.

[0043] [Fig. 4] Figure 4 represents a perspective view of an example of sliding cooperation of a tongue / groove assembly at the second electrical connector.

[0044] [Fig. 5A] Figure 5A represents a perspective view of an example of a wall-mounted device comprising a switch and a coiled charging cable according to the present invention.
