Description

[0001] The present invention relates to a display device for an e-bike. Technological background

[0002] Electric bicycles, commonly known as e-bikes, represent a major development in the world of cycling, combining the traditional riding experience with modern technology. These bikes expand the functionality of a conventional bicycle by integrating an electric drive system consisting of a motor, a battery, and a controller. The motor provides additional power while pedaling, which is especially beneficial on inclines or longer rides. The rechargeable battery powers the motor, and the controller allows the rider to regulate the intensity of assistance as needed.

[0003] E-bikes vary in design, with the most common types being pedelecs and S-pedelecs. Pedelecs assist the rider up to a speed of 25 km / h and are classified as regular bicycles in many countries. S-pedelecs, on the other hand, can reach speeds of up to 45 km / h and are therefore often subject to stricter regulations. There are also e-mountain bikes designed specifically for off-road use, which feature more robust components and powerful motors.

[0004] The advanced controls and functionality of electric bikes have significantly improved the riding experience by allowing the rider precise control over various aspects of the bike.

[0005] Another feature of modern e-bikes are displays or indicators that provide the user with important information and control options while riding. Depending on the model and manufacturer, the data and functions displayed may vary. Depending on the equipment, navigation functions, fitness data, and other convenience indicators may be added. Operation is usually via the display itself or a separate control unit.

[0006] The current state of the art presents several challenges and disadvantages. For example, the complexity of operating advanced systems while riding can cause problems. Likewise, the placement and size of some components on the handlebars can interfere with other parts of the bicycle, impairing clarity and usability. Maintenance and replacement are complicated, especially for systems with complex power and communication units. Furthermore, existing systems may not be sufficiently adaptable to different riding conditions, which can lead to limitations in situations where quick response and precise control are required.

[0007] There is therefore a need for improved displays that benefit the user. Expanded functionality, greater clarity, and user-friendliness are desirable. Description of the invention

[0008] One object of the invention is to avoid at least some of the disadvantages of the prior art. These objects are at least partially achieved by the features of the independent claim.

[0009] According to a first aspect of the invention, a display device for an e-bike is disclosed. This device comprises a display module for displaying information; a communication module for transmitting data; a power supply for the display module and the communication module; a housing that accommodates the display module, the communication module, the power supply, and a standby battery; and a solar module coupled to the standby battery, wherein the standby battery supports a radio module.

[0010] The solar module is preferably positioned so that radio communication with the radio module is possible. Radio communication should be unrestricted or free from interference. If a solar module covers a radio module, this may result in the radio module not functioning properly, and interference may occur.

[0011] In one embodiment, the battery supports a location determination module and the solar module is arranged such that unrestricted radio communication with the location determination module is provided.

[0012] One advantage of the display module is that it provides the user with all important information centrally, clearly, and in real time. This allows the user to view relevant data such as speed, battery level, assistance level, range, or navigation instructions at a glance while riding without distraction. This significantly increases safety and comfort. Other advantages of the modern display module include intuitive operation, customizability, integration of additional functions, compact design, increased safety, and weather resistance.

[0013] Clear menus and touchscreen functionality make the e-bike quick and easy to control. Users can customize the information displayed to their needs. Modern display modules offer interfaces to smartphone apps, navigation systems, or fitness trackers. Important warnings or error messages are displayed immediately, allowing the rider to react in a timely manner. The high-quality display module is robust, waterproof, and optimized for outdoor use. Overall, the display module contributes to making the riding experience more comfortable, safer, and more modern.

[0014] The solar module comprises at least two solar panels containing solar cells. The solar panels are arranged so that free wireless communication occurs between them. Each solar panel is positioned so that no radio or receiver module is covered or restricted. In the event of overlap, loss-free transmission and / or reception is not possible.

[0015] The solar panels can contribute to powering the standby battery, a camera, the display module, or both or all of the components. This enables a partially self-sufficient power supply, reduces the load on the main battery, and extends system runtime—especially when the engine is off or stationary.

[0016] It's advantageous to arrange the solar panels around the edge of the display unit or as a transparent layer above the screen. The latter allows for a dual function: incident light is used to generate power without obscuring the visible image. Ideal for direct sunlight in city traffic.

[0017] Alternatively, the display unit can feature a retractable or extendable solar panel that extends manually or automatically as needed. These options are particularly suitable for e-bikes that are stationary for extended periods, such as delivery services, travel, or breaks.

[0018] The display device can have a conical area in which the solar module with the solar panels is arranged. The conical shape allows for a defined area for the alignment and illumination of the solar panels. Arranging the panels in the conical area can help capture sunlight from different angles of incidence more effectively. This increases the energy yield of the solar module, which in turn supports a more reliable power supply to the battery or other electronic components.

[0019] If the display can be inserted into a form-fitting frame recess, it is easy to install and at least partially protected. Another advantage is that the display can be integrated particularly securely and stably into the bicycle frame. This prevents the display from slipping or falling out while riding, increasing operational safety. Furthermore, the precise integration enables an attractive, uncluttered appearance and better protects the display from external influences such as impacts, weather, or theft. Operation and readability remain comfortable, as the display is optimally positioned and firmly attached to the frame.

[0020] The display device advantageously has a frame area. It is particularly advantageous that the frame area around the display module can be used structurally to arrange additional functional elements. The lower area can also be designed to reinforce the structure and serve as a support for cabling, batteries, seals, or connectors.

[0021] The display module can display one or more of the following variables or information: speed, battery charge level, assistance level, indicator status (e.g., on / off / flashing), and rear view. Due to its positioning, the display module is in a good field of view for the rider and displays relevant information about the e-bike from a preferred angle.

[0022] The display module can incorporate thin-film transistor (TFT) technology with a TFT touchscreen. One advantage is their excellent readability and usability: TFT displays offer brilliant colors, high contrast, and a wide viewing angle, so information is clearly visible even in direct sunlight or difficult lighting conditions. The integrated touchscreen makes operation particularly intuitive and convenient, as display and control are combined in a single element. This enables flexible customization of the user interface and fast, safe navigation through menus, even with cycling gloves or in changing weather conditions. Users also benefit from modern additional functions such as navigation assistance, smartphone connectivity, and individually customizable data views, making the overall riding experience more comfortable and safer.

[0023] The display module can be 7 inches in size. One advantage is the generous and clear presentation of information. A 7-inch display offers sufficient space to clearly and legibly display important riding data such as speed, battery level, navigation instructions, and assistance levels without appearing cluttered. This simplifies operation, as larger controls and menus can be used more intuitively, which ensures greater safety, especially while riding. Furthermore, the larger screen area allows for the integration of additional functions such as map views, fitness data, or multimedia information without compromising clarity. A side-by-side field of view can also be displayed, further increasing riding safety. This display, which is preferably in real time, can complement mirrors or make them obsolete.

[0024] The display module can also be 4.3 inches in size. One advantage is its compact design, which allows for space-saving integration in or on the frame of the e-bike. Despite its smaller size, a 4.3-inch display offers sufficient space to present essential riding information clearly and legibly. Furthermore, the handy size ensures ergonomic operation, as the display module is easier to reach and intuitive to control. Furthermore, a smaller display module is often more energy-efficient and can thus contribute to longer battery life.

[0025] In a further advantageous embodiment, the display module is designed as a touch-sensitive display. This enables direct and intuitive user interaction. Operation can also be carried out while stationary, without the need for separate control elements. Particularly advantageously, the display module can be designed as a capacitive touchscreen that supports multi-touch inputs. This allows swipe and zoom gestures, for example, to enlarge the field of view or adjust the display without compromising riding safety. Alternatively, the touch-sensitive surface can be designed as a resistive touchscreen to ensure reliable operation even in the rain, when wearing gloves, or when dirty. This design is particularly suitable for robust e-bikes used in delivery or leisure applications.

[0026] In a further advantageous embodiment, the display module with touch display is limited to specific areas of the display unit, for example, to virtual buttons in a specific area. This means that the central or defined area remains reserved for a rearview display, for example, and is not obscured by finger movements.

[0027] The communication module can support one or more of the following standards: LTE Cat 1 bis, BT / BLE, Wi-Fi, UWB, V2X, and GNSS. Integration into the display module offers numerous advantages. LTE Cat 1 bis enables reliable, high-bandwidth mobile data transmission with good network coverage, especially for IoT and mobility applications. Cat 1 bis is particularly power-efficient, supports longer battery life, and is also suitable for devices that move or operate in remote areas. Bluetooth ®(BT / BLE) enables simple and energy-saving pairing with smartphones, sensors, or other accessories, e.g., for fitness tracking, app control, or the transmission of diagnostic data. Wi-Fi offers fast, local data transmission and enables software updates, cloud connections, or integration into other networks and hotspots. UWB (Ultra-Wideband) is a radio technology for wireless communication over very short distances that uses a particularly large bandwidth in the frequency spectrum, typically more than 500 MHz. UWB operates with very short pulses, enabling precise positioning and distance measurement between devices, often with an accuracy of a few centimeters. V2X (Vehicle-to-Everything) extends connectivity with safety-relevant functions by allowing the e-bike to communicate with other road users, infrastructure, or traffic management.This enables warnings, traffic information, and automated driving functions. The GNSS (Global Navigation Satellite System) ensures precise positioning and navigation, which is relevant for route guidance, theft protection, and fleet management. A display module with these technologies is future-proof, versatilely networkable, and enables numerous smart functions, from real-time navigation and safety features to efficient fleet management and convenient user connectivity.

[0028] In a preferred embodiment, new antennas are provided in the display device: 2x V2X, 2x WiFi, 2x GNSS, 1x BT / BLE, 1x UWB and 1x LTE.

[0029] The communication module can be coupled with sensors connected to a gyrometer and / or magnetometer. This allows precise movement and position information to be recorded and transmitted in real time. The integration of a gyrometer, for measuring rotational movements, and a magnetometer, for determining orientation in the Earth's magnetic field, enables advanced functions such as precise navigation, automatic alignment of displays, or the detection of falls and unusual movements. By combining the sensor data, movement profiles, driving dynamics, and changes in position can be analyzed very precisely, which can be used, for example, for assistance systems, safety functions, or fitness tracking. This coupling capability opens the system up to future expansion and adaptation, as additional sensors can be easily integrated. Critical situations such as falls or collisions can be detected more quickly, and appropriate measures, e.g.Emergency calls and warnings can be initiated automatically. A communication module that can be coupled with gyrometer and magnetometer sensors offers significantly expanded functionality, increases safety, and opens up numerous possibilities for innovative applications in the areas of mobility, sports, and security.

[0030] One advantage of coupling the communication module with additional sensors that provide tire pressure and / or ambient light readings is a significant expansion of the system's functionality and safety. By integrating tire pressure sensors, the current tire pressure can be monitored in real time and immediately displayed to the driver. This allows for early detection of gradual air leaks or critical pressure deviations, reducing the risk of accidents and improving driving stability. The driver receives convenient and automatic information about the condition of the tires and can identify maintenance needs in a timely manner without having to manually check the tire pressure. Optimal tire pressure reduces fuel consumption, lessens tire wear, and lowers CO2 emissions by optimizing the vehicle's rolling resistance.Tire pressure can also be reduced, for example, depending on the terrain and specified values ​​to ensure safe driving. An ambient light sensor allows the system to automatically adjust the display or display module brightness to the lighting conditions, improving readability and reducing energy consumption. The ability to connect to various sensor types makes the system flexible and future-proof, as it can easily be expanded with additional monitoring and convenience functions.

[0031] The housing can include a plug-shaped, flared coupling point. One advantage is the simple, secure, and stable connection to other components or cables. The coupling point also provides space for components, such as a standby battery. The plug-shaped design enables quick and uncomplicated installation, which also facilitates maintenance, replacement, or installation. The flared shape ensures a firm, positive connection that better withstands vibrations and mechanical stress and prevents accidental loosening. The precise fit allows the coupling point to be better sealed, which reduces the ingress of dust, moisture, or dirt and increases the service life of the connection. A housing with this type of coupling point offers a robust, user-friendly, and protective connection solution that simplifies assembly processes and increases the reliability of the overall system.
