Description

Technical Field

[0001] This utility model relates to the technical field of accessories for two-wheeled electric vehicles, and in particular to electronic rearview navigation mirrors for two-wheeled electric vehicles. Background Technology

[0002] With the fast pace of modern life, two-wheeled electric vehicles have become an important mode of transportation for urban commuting due to their flexibility and convenience. However, current two-wheeled electric vehicles suffer from numerous problems with rearview and navigation systems, seriously affecting riding safety and convenience.

[0003] Regarding rearview mirrors, traditional two-wheeled electric vehicles mostly use ordinary optical lenses. These lenses have poor reflectivity in low-light environments, such as at night or in tunnels, failing to effectively display the rear view. Furthermore, the rider's constantly changing riding posture alters the observation angle and the mirror's reflection angle, causing deviations in the rearview observation angle and posing significant safety hazards. Moreover, traditional rearview mirrors have a limited field of view, making it difficult to meet the rider's need for a comprehensive view of the rear in complex traffic conditions.

[0004] In terms of navigation, existing navigation devices offer a limited range of display options. Most can only display a fixed navigation map on a single screen, unable to flexibly switch to display other important information. Operationally, they largely rely on manual touchscreen input, which can distract riders and increase the risk of accidents while cycling. Furthermore, existing navigation devices struggle to effectively interact with other devices, hindering functional expansion.

[0005] Regarding dash cam recording, this device features a fully automatic, seamless recording technology: high-definition recording is triggered the moment the device starts, ensuring complete recording of the entire driving process. In terms of hardware configuration, it has a built-in high-capacity, high-speed storage module and is equipped with a large-capacity TF card slot to support storage expansion. It supports cyclic overwrite storage, enabling continuous storage of at least 3 days of video, eliminating the hassle of frequent manual clearing.

[0006] At the data interaction level, the system is deeply integrated with a dedicated mobile app. Users can connect with a single click via Bluetooth / Wi-Fi to quickly preview, download, delete, or export video files. Whether handling traffic accidents or tracing daily safety incidents, it enables efficient and convenient video management.

[0007] This device has an automatic brightness adjustment function, which can monitor the ambient brightness in real time through a light sensor and automatically adjust the brightness of the display screen. Utility Model Content

[0008] This utility model aims to at least partially solve one of the technical problems in the related art.

[0009] Therefore, the purpose of this utility model is to propose an electronic rearview navigation mirror for two-wheeled electric vehicles, which supports single and dual screen display switching to meet the needs of different scenarios. It is operated through an external Bluetooth handle, which is safe and convenient, reduces risks, integrates multiple functions, provides comprehensive information, and functions as a regular rearview mirror when the LCD screen is off, and has rich electronic functions when it is lit, combining aesthetics and practicality.

[0010] To achieve the above objectives, this utility model proposes an electronic rearview navigation mirror for a two-wheeled electric vehicle, comprising a one-way transparent glass, an LCD screen, a housing, a control circuit board, a mounting bracket, a camera, a GPS module, a Bluetooth module, and an external Bluetooth control handle. The housing is fixed to both sides of the handlebars via the mounting bracket; the LCD screen is embedded inside the housing, and the one-way transparent glass covers the front of the screen and is sealed to the housing; the control circuit board is integrated within the housing, and houses the GPS module and Bluetooth module; the camera includes two front and rear cameras fixed to the housing, and a third camera mounted at the rear of the vehicle via a waterproof cable connected to the control circuit board; the electronic rearview navigation mirror wirelessly communicates with the external Bluetooth control handle via the control circuit board.

[0011] This utility model of an electronic rearview navigation mirror for two-wheeled electric vehicles supports single and dual-screen display switching to meet the needs of different scenarios. It is operated via an external Bluetooth handle, which is safe and convenient, reduces risks, integrates multiple functions, provides comprehensive information, and functions as a regular rearview mirror when the LCD screen is off, and has rich electronic functions when lit, combining aesthetics and practicality.

[0012] In addition, the electronic rearview navigation mirror for two-wheeled electric vehicles proposed in the application may also have the following additional technical features:

[0013] Specifically, the display modes of the LCD screen include: single-mirror display mode: a single display screen can switch to display real-time images from the rear camera, navigation information, or time, direction, and speed information; dual-screen display mode: two display screens independently display navigation maps and rear images or time, direction, and speed information, and the display content is configured via a Bluetooth control handle.

[0014] Specifically, the one-way transparent glass has a semi-reflective and semi-transmissive structure. When not powered on, it is used as a traditional rearview mirror. When powered on, it allows light from the display screen to pass through and be displayed. The camera located at the rear of the vehicle is a wide-angle lens and integrates an infrared fill light module. At night, the night vision mode is activated through the control circuit board.

[0015] Specifically, the GPS module and map database are integrated into the control circuit board, which obtains the vehicle's location through satellite positioning and generates navigation routes; the Bluetooth module supports data interaction with mobile phones and dashcams.

[0016] Specifically, it also includes a light sensor, which is mounted on the surface of the housing and electrically connected to the control circuit board to monitor the ambient brightness in real time and automatically adjust the brightness of the display screen.

[0017] Specifically, it also includes millimeter-wave radar, which is integrated into the housing and connected to the control circuit board, and triggers a warning signal by monitoring moving objects behind.

[0018] The advantages of this invention compared to existing technologies are as follows:

[0019] (1) It supports two modes: single-mirror display and dual-screen display. Riders can switch freely according to their actual needs to meet the usage requirements of different scenarios, which greatly improves the practicality and applicability of the device.

[0020] (2) The device can be operated via an external Bluetooth control handle. Riders do not need to touch the screen with their hands. This allows them to control the device more safely and conveniently during the ride, effectively reducing distraction and safety risks.

[0021] (3) It can be operated through external voice commands, which makes it safer and more convenient to control the equipment during riding, effectively reducing distraction and lowering safety risks.

[0022] (4) It integrates rearview, navigation, ambient brightness adaptive adjustment and intelligent assistance functions, providing riders with comprehensive information support and helping to improve the safety and convenience of driving two-wheeled electric vehicles.

[0023] (5) It has a driving recorder function, allowing users to quickly view the entire driving video on the device, or quickly preview, download, or export video files through a dedicated mobile app. Whether for handling traffic accidents or tracing daily safety issues, it can achieve efficient and convenient video management.

[0024] (6) When the LCD screen is not lit, the navigation mirror is used as a regular rearview mirror, which does not affect the overall aesthetics of the vehicle. When the screen is lit, it can provide a wealth of electronic functions, achieving a perfect combination of aesthetics and practicality.

[0025] (7) Users can freely choose different product versions to match according to their own needs. For example, users can choose the pure navigation version, which does not include a camera and is only used as a navigation mirror; or they can choose the version with front and rear cameras and a rear camera, which can be used as an electronic rearview mirror + dashcam + navigation mirror.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0034] The following description, in conjunction with the accompanying drawings, describes an embodiment of the electronic rearview navigation mirror for two-wheeled electric vehicles.

[0035] like Figures 1-4 As shown, the electronic rearview navigation mirror for a two-wheeled electric vehicle according to this utility model embodiment includes a one-way transparent glass 1, a liquid crystal display screen 2, a housing 3, a control circuit board 4, a mounting bracket 5, cameras including two front and rear cameras 6 fixed on the housing 3 and a rear tail camera 6 installed at the rear of the vehicle body, a GPS module 7, a Bluetooth module 8, and an external Bluetooth control handle 9.

[0036] The first step, as is understandable, is the installation process. The outer casing 3 is secured to both sides of the handlebars of the two-wheeled electric vehicle using mounting brackets 5. Mounting brackets 5 provide stable support, ensuring the outer casing 3 is securely installed and positioned for easy observation by the rider.

[0037] After installation, all components begin to work together. The LCD screen 2 is embedded inside the housing 3, and the one-way mirror 1 covers the front of the LCD screen 2 and is sealed to the housing 3. This design protects the LCD screen 2 while meeting observation needs in different states. When the LCD screen 2 is not turned on, the one-way mirror 1 can be used as a traditional reflector, making it convenient for the rider to observe the situation behind. When the LCD screen 2 is turned on, the light emitted by it can pass through the one-way mirror 1, allowing the rider to see the displayed content.

[0038] The control circuit board 4 is integrated within the housing 3, where the GPS module 7 and Bluetooth module 8 play crucial roles. The GPS module 7 can acquire the vehicle's location information in real time. For example, during riding, it determines the vehicle's exact location by receiving satellite signals and transmits this location information to the control circuit board 4.

[0039] It should be noted that control circuit board 4 also integrates a storage module, a communication module, a lighting control module, and a voice interaction module. Among these:

[0040] Storage module: Supports external storage card expansion. It is electrically connected to the control circuit through the card slot on the circuit board and is used to store the audio and video data and trajectory logs of the dashcam. The storage module supports 256GB storage card expansion through the circuit board card slot and is used for loop recording of front and rear camera images.

[0041] Communication module: It adopts a 4G / 5G communication module, which realizes data transmission through metal pins soldered to the control circuit board, and can update map data and upload emergency images in real time;

[0042] Lighting control module: The lighting alert function is achieved through colored lights on the edge of the outer casing 3, specifically:

[0043] When there is an external communication call, the green LED light bead is driven to flash through the control circuit;

[0044] When danger is detected or a warning message is displayed, the red LED light will flash.

[0045] Voice interaction module: The microphone and speaker are connected to the control circuit through the audio interface. After receiving voice commands such as "navigate home", the commands are processed by the analog-to-digital conversion circuit and sent to the navigation module through the communication module. The result is then broadcast by the speaker.

[0046] A camera 6, located at the rear of the vehicle, is mounted on the rear of the frame and connected to the control circuit board 4 via a waterproof cable. The waterproof cable ensures that the rear camera 6 can reliably transmit real-time video data captured from behind to the control circuit board 4 in various weather conditions. The control circuit board 4 processes the received video data and then transmits it to the LCD screen 2 for display, allowing the rider to stay informed about the situation behind them.

[0047] It should be noted that the six cameras are divided into a front camera (integrated in housing 3, capturing road conditions ahead for driving recording), a rear camera (for facial recognition, video communication, head movement, or gesture control), and a rear-view camera (wide-angle night vision at the rear of the vehicle). Among them:

[0048] The front-facing camera 6 is fixed with the housing 3 and is electrically connected to the storage module through the data interface on the control circuit board. It can record cycling perspective images and automatically overwrite old data in a loop.

[0049] The rear camera 6 is fixed to the cyclist along with the housing 3 and is used for facial recognition, video communication, head movement or gesture control. It is electrically connected to the storage module through the data interface on the control circuit board and can record images of the cyclist's riding status and automatically overwrite old data in a loop.

[0050] The external Bluetooth control handle 9 communicates wirelessly with the electronic rearview navigation mirror via the Bluetooth module 8 on the control circuit board 4. The rider can send commands to the control circuit board 4 by operating various buttons on the external Bluetooth control handle 9. For example, pressing the button to switch display modes will cause the control circuit board 4 to switch between different display modes on the LCD screen 2 upon receiving the command; pressing other function buttons allows for operations such as destination input confirmation and navigation route planning.

[0051] It should be noted that:

[0052] Supports modular optional configurations:

[0053] Version 1: Single screen + front and rear cameras + navigation + dashcam;

[0054] Version 2: Single screen + front and rear cameras + navigation + dashcam + rear-view camera;

[0055] Version 3: Dual screens + navigation + front and rear cameras + dashcam + rear-view camera; (achieved by adding a rear-view camera 6 and a storage module);

[0056] The pure navigation version has no camera (6), and only retains the single-screen + navigation function.

[0057] In one embodiment of this utility model, such as Figures 1-4As shown, the display modes of the LCD screen 2 include: single-mirror display mode: a single screen can switch to display real-time images from the rear camera 6 or navigation information; dual-screen display mode: two screens can independently display navigation maps and rear images respectively, and the display content is configured via an external Bluetooth control handle 9.

[0058] Among these, it is understandable that the workflow of the single-lens display mode is as follows.

[0059] In single-lens display mode, only one LCD screen 2 is used. In this mode, the display content is switched by an external Bluetooth controller 9, and the control signal is transmitted to the control circuit board 4 via Bluetooth module 8.

[0060] If the rider wants to observe the situation behind them, they can operate the external Bluetooth control handle 9 to issue a command to display the rear image. This command is transmitted to the control circuit board 4 via the Bluetooth module 8. After receiving the command, the control circuit board 4 obtains real-time image data from the rear camera 6, which is connected to it via a waterproof cable. The processed data is then transmitted to the LCD screen 2, which displays the real-time rear view captured by the rear camera 6.

[0061] When a rider needs navigation, they can directly input their destination information on the touchscreen LCD 2. The command is also transmitted to the control circuit board 4 via the touchscreen LCD 2. The GPS module 7 integrated on the control circuit board 4 receives satellite signals, determines the vehicle's current location, and, in conjunction with the built-in map database, plans a navigation route to the destination. After processing the navigation route and other relevant information, the control circuit board 4 transmits it to the LCD 2, which then displays navigation information such as route, distance, and turn prompts. Alternatively, the destination information can be input via a dedicated mobile app and sent to the control circuit board 4 via Bluetooth / Wi-Fi. After the above process, the navigation information is finally displayed on the LCD 2.

[0062] Dual-screen display mode workflow

[0063] In dual-screen display mode, there are two LCD screens 2. These two screens work independently, and their displayed content can be flexibly configured via an external Bluetooth control handle 9.

[0064] The navigation map displays the following: Cyclists can directly input their destination information on the touchscreen LCD 2, and the commands are also transmitted to the control circuit board 4 via the touchscreen LCD 2. The GPS module 7 integrated on the control circuit board 4 receives satellite signals, determines the vehicle's current location, and, in conjunction with the built-in map database, plans a navigation route to the destination. After processing the navigation route and other relevant information, the control circuit board 4 transmits it to the LCD 2, which then displays the navigation information, such as route, distance, and turn prompts. Alternatively, the destination information can be input via a dedicated mobile app and sent to the control circuit board 4 via Bluetooth / Wi-Fi. The navigation information is then displayed on the LCD 2. Alternatively, the destination information can be input directly via voice input through a Bluetooth headset or microphone and sent to the control circuit board 4. The navigation information is then displayed on the LCD 2.

[0065] Rear view display: Simultaneously, the rear camera 6 continuously captures real-time footage of the area behind the vehicle and transmits the image data to the control circuit board 4 via a waterproof cable. The control circuit board 4 processes the image data and then transmits it to another LCD screen 2 for independent display of the real-time rear view.

[0066] In one embodiment of this utility model, such as Figures 1-4 As shown, the one-way transparent glass 1 has a semi-reflective and semi-transmissive structure. When not powered on, it is used as a traditional reflector. When powered on, it allows light from the LCD screen 2 to pass through and be displayed. The camera 6 is a wide-angle lens and integrates an infrared fill light module. At night, the night vision mode is activated through the control circuit board 4.

[0067] It is understandable that the unique semi-reflective and semi-transmissive structure of the one-way mirror 1 allows it to function like a traditional rearview mirror when the LCD screen 2 is not powered on. Its semi-reflective properties mean that most of the light shining on the glass surface is reflected back. In this state, the rider can observe the area behind the vehicle through the light reflected from the one-way mirror 1, just like using a regular electric vehicle rearview mirror.

[0068] Power-on state: When the LCD screen 2 is powered on, the one-way mirror glass 1 allows light emitted from the LCD screen 2 to pass through. The light emitted from the LCD screen 2 passes through the one-way mirror glass 1, clearly presenting the displayed content to the rider. For example, when the LCD screen 2 displays navigation maps, real-time images captured by the rear camera 6, etc., the light passes through the one-way mirror glass 1, allowing the rider to access this electronic information and meet their usage needs in different scenarios.

[0069] The rear camera 6 is equipped with a wide-angle lens and integrates an infrared fill light module. In normal lighting conditions: Under sufficient light, the wide-angle lens of the rear camera 6 comes into play, capturing a large area behind the vehicle. The wide angle of view of the wide-angle lens can cover more rear areas, reducing blind spots and allowing the rider to clearly see the real-time situation behind them.

[0070] Nighttime or Low-Light Environments: When in nighttime or low-light environments, the control circuit board 4 activates the night vision mode of the camera 6. When low ambient light is detected, the night vision mode command is automatically triggered. Upon receiving the command, the infrared illumination module integrated into the camera 6 begins operation, emitting infrared light. This infrared light illuminates objects behind the camera and reflects back to the camera 6, enabling it to capture clear images. The camera 6 transmits these infrared-illuminated image data to the control circuit board 4, which processes the images to enhance clarity and visibility. Finally, the processed image data is sent to the LCD screen 2 for display, ensuring that the rider can clearly observe the situation behind them even at night or in low-light conditions, thus guaranteeing riding safety.

[0071] In one embodiment of this utility model, such as Figures 1-4 As shown, the GPS module 7 and the map database are integrated into the control circuit board 4. The GPS module 7 obtains the vehicle's location through satellite positioning and generates a navigation route. The Bluetooth module 8 supports data interaction with external devices such as mobile phones and dashcams.

[0072] As can be understood, when the electronic rearview navigation mirror is activated, the GPS module 7 integrated into the control circuit board 4 begins receiving satellite signals and determines the vehicle's position through calculation. If the rider inputs the destination using an external Bluetooth control handle 9, the command is transmitted to the control circuit board 4 via the Bluetooth module 8. The control circuit board 4 combines the vehicle's position with a map database to plan a navigation route and transmits the route information to the LCD screen 2 for display.

[0073] Enable Bluetooth on the electronic rearview navigation mirror, mobile phone, and dashcam to pair and connect. After connection, the mobile phone can transmit data such as contacts and music playlists to Bluetooth module 8, which is processed by control circuit board 4; Bluetooth module 8 can also transmit navigation information to the mobile phone. The dashcam can transmit video data to Bluetooth module 8, which is stored and processed by control circuit board 4; at the same time, control circuit board 4 can send control commands to the dashcam via Bluetooth module 8.

[0074] In one embodiment of this utility model, such as Figures 1-4 As shown, it also includes a light sensor 10, which is mounted on the surface of the housing 3 and electrically connected to the control circuit board 4 to monitor the ambient brightness in real time and automatically adjust the brightness of the LCD screen 2.

[0075] As can be understood, the light sensor 10 is mounted on the surface of the housing 3 and electrically connected to the control circuit board 4. When the electronic rearview navigation mirror is working, the light sensor 10 monitors the ambient brightness in real time and transmits the brightness data to the control circuit board 4. After receiving the data, the control circuit board 4 automatically adjusts the brightness of the LCD screen 2 according to preset brightness adjustment rules to ensure that the rider can clearly see the content on the screen under different lighting conditions.

[0076] In one embodiment of this utility model, such as Figures 1-4 As shown, it also includes a millimeter-wave radar 11, which is integrated into the housing 3 and connected to the control circuit board 4. It triggers a warning signal by monitoring moving objects behind.

[0077] It is understood that during the operation of the electronic rearview navigation mirror, the millimeter-wave radar 11 integrated within the housing 3 continuously transmits millimeter-wave signals and receives the reflected signals. When a moving object enters the monitoring range from behind, the millimeter-wave radar 11 determines information such as the distance, speed, and direction of the moving object based on changes in the reflected signal.

[0078] The millimeter-wave radar 11 transmits this monitoring data to the control circuit board 4 in real time. Upon receiving the data, the control circuit board 4 analyzes and processes it. If it determines that a moving object may pose a safety threat to the rider, such as a vehicle rapidly approaching from behind, the control circuit board 4 will trigger a warning signal. This warning signal is presented to the rider through audible alerts and flashing of the LCD screen 2, reminding them to pay attention to the situation behind them and ensuring riding safety.

[0079] It should be noted that the control method of this application can be automatically controlled by a controller. The control method of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical structures, so the control method and circuit connection will not be explained in detail here.

[0080] Specifically, the entire process of using electronic rearview navigation mirrors for two-wheeled electric vehicles:

[0081] 1. Installation preparation: Securely install the navigation mirror housing 3 on both sides of the handlebars using the mounting bracket 5, ensuring that the installation position is convenient for the rider to observe.

[0082] 2. Start the device: Turn on the electric vehicle, and the navigation mirror will start. The light sensor 10 monitors the ambient brightness in real time and transmits the data to the control circuit board 4, which automatically adjusts the brightness of the LCD screen 2 to ensure clear display.

[0083] 3. Observe the rear: If you need to check the situation behind you, the rider operates the external Bluetooth control handle 9 to issue a command to display the rear image. The command is transmitted to the control circuit board 4 via the Bluetooth module 8. The control circuit board 4 obtains real-time image data from the camera 6 located at the rear of the vehicle, processes it, and displays the rear view on the LCD screen 2.

[0084] 4. Navigation: For navigation, riders can directly input their destination information on the touchscreen LCD 2. The command is also transmitted to the control circuit board 4 via the touchscreen LCD 2. The GPS module 7 integrated on the control circuit board 4 receives satellite signals, determines the vehicle's current location, and, combined with the built-in map database, plans a navigation route to the destination. The control circuit board 4 processes the navigation route and other relevant information and transmits it to the LCD 2, which then displays navigation information such as route, distance, and turn prompts. Alternatively, the destination information can be input via a dedicated mobile app and sent to the control circuit board 4 via Bluetooth / Wi-Fi. The navigation information will then be displayed on the LCD 2. Alternatively, the destination information can be input directly via voice input through a Bluetooth headset or microphone and sent to the control circuit board 4. The navigation information will then be displayed on the LCD 2.

[0085] 5. Nighttime or Low-Light Environments: When entering nighttime or low-light environments, the control circuit board 4 automatically activates the night vision mode of the camera 6. Its infrared supplementary lighting module works to capture clear images, which are then transmitted to the control circuit board 4 for processing and display on the LCD screen 2. Simultaneously, the millimeter-wave radar 11 continuously monitors moving objects behind the rider. If a safety threat is detected, the control circuit board 4 triggers a warning signal, alerting the rider through sound and flashing of the LCD screen 2.

[0086] It should be noted that the rearview mirror is equipped with a rear-facing camera and microphone for rider control via voice and gestures. Specifically:

[0087] The rear-facing camera, fixed to the front of the housing 3, uses a wide-angle lens (view of ≥100°) to capture the rider's head movements or gestures (such as waving or nodding) in real time. The control circuit board 4 integrates hardware logic processing circuitry, which presets the mapping relationship between head movements or gestures and function commands (e.g., shaking the head to the left or waving to switch to dual-screen display mode, raising the head and waving to adjust the display brightness). The circuit logic converts the image signals captured by the rear camera 6 into control commands.

[0088] The microphone is embedded in the surface of the housing 3 and connected to the analog-to-digital converter module of the control circuit board 4 via an audio cable to collect voice commands (such as "turn on navigation" or "switch to rearview view"). After the voice signal is filtered and amplified by hardware, it is processed by the hardware command recognition circuit of the control circuit board 4, and the voice commands are converted into control commands by software.

[0089] Control signal transmission path: The signals from the front-facing camera and microphone facing the rider are all connected through the hardware interface circuit of the control circuit board 4. After being processed by the logic circuit, the signals drive the LCD screen 2 to switch the display content or control the working status of the camera 6 located at the rear of the vehicle.

[0090] In summary, the electronic rearview navigation mirror for two-wheeled electric vehicles of this utility model embodiment supports single and dual-screen display switching to meet the needs of different scenarios. It is operated via an external Bluetooth handle, which is safe and convenient, reduces risks, integrates multiple functions, provides comprehensive information, and functions as a regular rearview mirror when the LCD screen is off, and has rich electronic functions when it is on, combining aesthetics and practicality.
