Description

1. Technical field

[0001] The invention relates to a modular energy generation system for the autonomous generation of electrical energy by means of rotating generators that are mounted on suitcase wheels or hubs of luggage or on mobile support devices (such as walking sticks, umbrellas, telescopes and various walking sticks). In particular, the invention relates to the integration of this energy generation unit into an extremely flat, narrow housing with standardized fast-charging interfaces (USB-C PD) and a wireless energy transfer zone (Qi standard) as well as a universal, detachable mounting solution. 2. State of the art

[0002] Conventional power generation systems on mobile luggage racks provide basic power, but do not support modern charging convenience requirements (wireless charging zones) or modern fast-charging protocols (USB-C Power Delivery). Furthermore, existing mounting solutions often use complex or form-fitting fasteners that are not suitable for every piece of luggage or support device. Therefore, there is a need for a flatter, more universally mountable, and multifunctional power supply unit that integrates these modern charging standards. 3. Object of the invention

[0003] The task is to provide a compact, easily integrated and retrofittable power generation system that solves the following challenges: • The system's universal applicability to both rolling carriers (luggage) and mobile support devices (staff types). • The integration of state-of-the-art charging interfaces, in particular a wireless Qi charging zone and a high-performance USB-C interface with PD protocol support. • The creation of an extremely flat and narrow housing shape for the electronics as well as a narrow overall design for the generator arrangement. • The provision of a universal, modular fastening method that allows for quick and releasable assembly and disassembly of the electronic module. • The creation of an aesthetic and comfortable solution for mounting on the inside of luggage. 4. Solution to the task

[0004] The task is solved by the following combination of features: The system is housed in an extremely flat casing that integrates a Qi wireless charging zone and provides a USB-C output interface with a USB-PD controller. The generator can be attached to the hub, wheel, or support device (such as walking sticks, umbrellas, telescopes, and various walking sticks) using a design that keeps the overall assembly extremely flat or narrow.

[0005] The electronics housing is mounted using a separate, flat mounting platform designed for permanent attachment to the outer surface of the case or support device. This platform features a releasable snap-in or click-in mechanism for quick removal of the housing. When mounted inside the case, a smartphone pocket is also provided to conceal the mounting hardware and secure the device. 5. Advantages of the invention • Maximum charging convenience thanks to the wireless Qi charging zone. • Future-proof fast charging function via USB-C PD. • Universal, modular fastening (adhesive, screws, snap-in) for maximum retrofitability and use as needed. • Extremely flat, narrow housing designs for minimal space requirements. • An aesthetic and secure solution for mounting inside a suitcase using a smartphone pocket. 6. Structure and Function

[0006] The functionality of the invention is based on the modular combination of the following components, which are relevant to the claims: • Extremely flat housing: A single housing to accommodate all electronic components. • Snap-in housing platform: A separate mounting plate for permanent attachment, featuring a click function. • Ktick function: The mechanical element for the detachable connection of the housing and housing platform. • Alternative generator: A mini or micro generator whose design differs from a conventional three-phase generator in order to ensure a narrow design of the overall arrangement. • Wireless charging zone: The charging coil integrated into the surface of the housing according to the Qi standard. • USB-C interface & USB-PD controller: The cable output interface and the chip for negotiating the fast charging voltage profiles. • Smartphone pocket: An integrated or detachable pocket for aesthetically concealing the fastening elements when mounted inside the case and / or attached to a walking umbrella and various walking sticks.
