Technical Field

[0001] This application relates to the field of bicycle technology, and more particularly to an ambient light control method and a freight bicycle. Background Technology

[0002] Most traditional bicycles on the market do not have ambient lighting and cannot create a striking appearance through light-emitting components. Although some bicycles are decorated with light-emitting components, these components mostly only work in a constant-on mode, resulting in poor decorative effects. Furthermore, because these light-emitting components cannot be integrated with the bicycle itself, especially with the operating status of cargo bicycles, they cannot help users understand the operating status of cargo bicycles. Summary of the Invention

[0003] The main purpose of this application is to provide an ambient light control method and a freight bicycle, which aims to solve the technical problem that the decorative effect of the light-emitting components installed on the freight bicycle is not good, and that they cannot work according to the operating status of the freight bicycle and thus cannot display the operating status of the bicycle.

[0062] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0063] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0064] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0065] This application proposes an ambient light control method and a freight bicycle, which controls the operation of the light-emitting components in conjunction with the operating status of the freight bicycle, thereby more clearly and explicitly displaying the bicycle's status while optimizing the decorative effect of the light-emitting components.

[0066] The ambient lighting control method of this application is applied to a freight bicycle, which includes at least a bicycle body and a light-emitting component for emitting light, wherein the light-emitting component is provided on at least one side of the bicycle. The light-emitting component of this application is used as an ambient light to operate in a corresponding lighting mode according to different operating states of the freight bicycle, and to create a specific atmosphere to indicate the operating status of the freight bicycle, optimize the decorative effect, and to a certain extent serve as a safety reminder.

[0067] In some embodiments, when the bicycle body is provided with a cargo box, the aforementioned light-emitting component may be optionally provided on at least one side of the cargo box to use ambient lighting in conjunction with the cargo box structure and to reduce the space occupied by the light-emitting component on the bicycle body.

[0068] In some other embodiments, in addition to providing the aforementioned light-emitting components on at least one side of the cargo box, light-emitting components can also be provided at any other location on the bicycle. Specifically, the aforementioned light-emitting components can be provided at any location on the front, left, right, or rear side of the bicycle body to cooperate with the bicycle structure for use as ambient lighting, and can still create a specific atmosphere through the light-emitting components even when the cargo box is removed from the bicycle body.

[0069] In addition, the freight bicycle of this application also includes a control module (e.g., a central processing unit, a graphics processing unit, etc.), which can perform various appropriate actions and processes according to programs stored in read-only memory (ROM) or programs loaded from storage devices into random access memory (RAM). The RAM also stores various programs and data required to implement the intelligent lighting control method. The control module and storage modules such as ROM and RAM are interconnected as memory via a bus; the storage modules may also include storage devices such as magnetic tapes or hard disks. In this embodiment, for ease of description, the control module is mainly used as the execution entity.

[0070] Reference Figures 1 to 6 The ambient lighting control method includes the following steps:

[0071] Step S100: Obtain the current operating parameters of the freight bicycle.

[0072] Optionally, the operating parameters of the freight bicycle include its motion status and working status, and the acquired operating parameters are used to provide feedback on the operating status of the freight bicycle. The freight bicycle is equipped with a status detection component, which includes one or a combination of speed detection, tilt angle detection, auxiliary wheel angle detection, brake signal detection, camera, millimeter-wave radar, button status detection, and communication components, used to detect the motion status of the freight bicycle. The speed detection component includes wheel sensors to detect the running speed of the freight bicycle, such as wheel speed; the tilt angle detection component includes tilt sensors to detect the tilt angle of the freight bicycle; the auxiliary wheel angle detection component includes angle encoders or gyroscopes to detect the auxiliary wheel angles, such as rotation angle; the brake signal detection component is used to detect the braking status; the camera is used to detect the environmental image, and the millimeter-wave radar is used for distance measurement. The camera and millimeter-wave radar can be used to determine the distance and position of targets such as oncoming vehicles, pedestrians, and buildings; the button status detection component is used to detect operating mode setting commands, operating mode switching commands, power-on signals, and power-off signals generated when the switch module and operation buttons are triggered, in order to determine the operating mode and power-on / off status; the communication component is used to connect with the microphone, external control devices, or other working parts of the freight bicycle to obtain commands such as requests for the freight bicycle to change lanes to the left or right, to further determine the operating mode, and also to obtain abnormal signals transmitted when working parts such as the brakes, camera, and millimeter-wave radar malfunction, in order to determine abnormal status information. In addition, the status detection component may also include a power detection component and other detection components used to detect the working status of the freight bicycle, wherein the power detection component is used to detect the power of the freight bicycle.

[0073] Step S200: Determine the light emission mode of the light-emitting component based on the current operating parameters, and control the operation of the light-emitting component.

[0074] Optionally, specific operating parameters or operating parameter ranges can be set according to different operating states of the freight bicycle, which are used to determine the operating state of the freight bicycle based on the acquired operating parameters. Multiple lighting modes are preset for different operating states of the freight bicycle, and the lighting mode of the lighting component is determined based on the acquired operating parameters of the freight bicycle. The lighting component is then controlled to operate according to the corresponding working mode. This allows for a variety of lighting modes, effectively improving the flexibility of lighting control and optimizing the decorative effect of the lighting component.

[0075] By controlling the light-emitting components to illuminate according to the operating mode corresponding to the current operating parameters of the freight bicycle, the system displays the bicycle's status and helps users understand its operational status. This setup also serves as a safety reminder to users and other road users, effectively optimizing safety to a certain extent.

[0076] In one embodiment, the freight bicycle is equipped with a status detection component, which includes one or more of the following: a speed detection component, a tilt angle detection component, an auxiliary wheel angle detection component, a brake signal detection component, a camera, a millimeter-wave radar, a button status detection component, and a communication component.

[0077] Step S100, obtaining the current operating parameters of the freight bicycle, specifically includes:

[0078] The current operating parameters of the freight bicycle transmitted by the status detection component include one or more of the following: operating speed, bicycle tilt angle, auxiliary wheel angle, braking status, distance to environmental target object, location of environmental target object, operating mode, power on / off status, and abnormal status information.

[0079] Specifically, it can correspond to one or more combinations of operating parameters such as running speed, bicycle tilt angle, training wheel angle, braking status, distance to environmental target object, location of environmental target object, operating mode, power on / off status, and abnormal status information. Multiple light-emitting modes are preset to determine the operating mode of the light-emitting component based on the detected current parameters of the freight bicycle, such as running speed, bicycle tilt angle, and training wheel angle, and to control the operation of the light-emitting component according to the determined light-emitting mode.

[0080] In embodiments of this application, the light emission mode can be specifically set by configuring the luminous brightness, color temperature, duty cycle, and luminous duration of the light-emitting component. In one embodiment, the light-emitting component includes multiple LEDs. At least some of the LEDs have different colors, and the light emission mode includes at least one and a combination of multiple LEDs, such as the luminous emission sequence, luminous brightness, luminous duration, and luminous interval. Furthermore, different light emission modes can be further configured by setting different positions, different luminous colors, different operating brightnesses, and different luminous emission sequences, luminous brightness, luminous duration, and luminous intervals of the LEDs.

[0081] Optionally, the freight bicycle also includes an environmental detection component for detecting environmental parameters. Specifically, the environmental detection component includes, but is not limited to, temperature and humidity sensors, wind speed sensors, wind direction sensors, and illuminance sensors. These components detect environmental parameters and, based on the detected environmental parameters such as temperature, humidity, wind speed, wind direction, and illuminance, further set the operating mode of the light-emitting component. This allows the light-emitting component to operate according to different set light-emitting modes at different times and in different environmental scenarios.

[0082] In some optional embodiments of this application, the freight bicycle is equipped with a switch module such as a control switch and operation buttons such as user buttons. When these buttons are triggered, corresponding instructions are generated, and the generated instructions are detected by a button status detection component.

[0083] Optionally, the switch module is used to input a power-on signal or a power-off signal when triggered. The control module has a preset power-on mode, and after receiving the power-on signal, the control module controls the light-emitting components to work according to the preset power-on mode. Specifically, at least some of the LEDs in multiple light-emitting groups are controlled to work in a flowing light pattern at a set time interval.

[0084] In addition, the control module has a preset shutdown mode. Upon receiving a shutdown signal, the control module controls the light-emitting components to operate according to the preset shutdown mode. Specifically, it sequentially controls at least a portion of the LEDs in multiple light-emitting groups to operate in a flowing light pattern for a set second time according to a set time interval. In the shutdown mode, the light-emitting sequence, brightness, duration, and time interval of the multiple LEDs in the light-emitting components are at least partially different from those in the power-on mode.

[0085] Reference Figure 2 In one embodiment, the light-emitting component includes multiple light-emitting groups, each light-emitting group including at least one LED; the operating speed of the freight bicycle is determined by the operating speed detected by the speed detection component.

[0086] Step S200: Determine the light emission mode of the light-emitting component based on the current operating parameters. The steps for controlling the operation of the light-emitting component include:

[0087] Step S211: When the freight bicycle is running at high speed according to the current operating parameters, control the LED beads of multiple light-emitting groups to work sequentially according to the set first time interval.

[0088] Step S212: When the freight bicycle is running at medium speed according to the current operating parameters, control the LED beads of multiple light-emitting groups to work sequentially according to the set second time interval.

[0089] Step S213: When the freight bicycle is running at low speed according to the current operating parameters, control the LED beads of multiple light-emitting groups to work sequentially according to the set third time interval.

[0090] Understandably, the light-emitting component includes multiple light-emitting groups, each group containing at least one LED. These groups are arranged in multiple rows, or multiple columns. The control module controls the light-emitting component to operate in a flowing light pattern, illuminating the LEDs one by one, row by row, or column by column according to the different speeds of the freight bicycle, thus creating a desired gradual change in the LED speed. A third time interval > a second time interval > a first time interval is used to set the changing speed of the LEDs. When the freight bicycle is running at high speed, the light-emitting component operates at a fast pace; when the freight bicycle is running at medium speed, the light-emitting component operates at a medium pace; and when the freight bicycle is running at low speed, the light-emitting component operates at a slow pace.

[0091] As a specific embodiment of this application, optionally, a night riding mode is set according to the operating speed of the freight bicycle. The mode is set so that the LEDs in the light-emitting group only operate according to the set night riding mode when the illuminance sensor detects a nighttime environment or a low-visibility environment, and the freight bicycle's riding speed is not less than 5 km / h. Further, in some embodiments of this application, the color temperature change rate of the light-emitting component can also be controlled in conjunction with the freight bicycle's operating speed, used to control the LEDs to operate according to set brightness, color, and operating time when controlling the corresponding LEDs. Specifically, a riding speed greater than 5 km / h and not greater than 10 km / h is defined as low-speed operation; a riding speed greater than 10 km / h and not greater than 15 km / h is defined as medium-speed operation; and a riding speed not less than 15 km / h is defined as high-speed operation. When the freight bicycle is running at high speed, the LEDs of multiple light-emitting groups are controlled to work at a fast pace in the form of flowing lights according to the first set time interval; when the freight bicycle is running at medium speed, the LEDs of multiple light-emitting groups are controlled to work at a medium pace in the form of flowing lights according to the second set time interval; when the freight bicycle is running at low speed, the LEDs of multiple light-emitting groups are controlled to work at a slow pace in the form of flowing lights according to the third set time interval.

[0092] Reference Figure 5 , Figure 6 In one embodiment, the light-emitting component includes a first light-emitting component and a second light-emitting component disposed opposite to each other on the front and rear sides of the cargo box. There are two second light-emitting components, one of which is disposed near the left side of the cargo box and the other is disposed near the right side of the cargo box.

[0093] Specifically, the cargo box has at least one recessed mounting groove along its periphery for mounting light-emitting components. The mounting groove includes a first mounting groove and a second mounting groove. The first mounting groove is located on the front side of the cargo box and partially surrounds it, for mounting the first light-emitting component. The second mounting groove is located on the rear side of the cargo box for mounting the second light-emitting component, such that the first and second light-emitting components are positioned opposite to each other on the front and rear sides of the cargo box. There are two second mounting grooves for mounting two second light-emitting components. One of the two second mounting grooves is located at a bend between the left and rear sides of the cargo box, and the other is located at a bend between the right and rear sides of the cargo box, such that one of the two second light-emitting components is positioned closer to the left side of the cargo box, and the other closer to the right side. This application mainly controls the operation of the light-emitting components through a control module. Specifically, one control module can simultaneously control both the first and second light-emitting components; or, multiple control modules can be provided to separately control the first and second light-emitting components.

[0094] Optionally, the first light-emitting component includes a central light-emitting section, and left and right light-emitting sections respectively disposed on the left and right sides of the central light-emitting section. Each of the central, left, and right light-emitting sections includes multiple LEDs. The arrangement of the central, left, and right light-emitting sections, in conjunction with the second light-emitting component, simulates the indicator function of a car's front and rear lights. The central light-emitting section primarily serves a decorative purpose; specifically, it can be controlled to remain constantly lit or operate according to a set decorative mode based on the current operating parameters of the freight bicycle. Furthermore, it has a preset lighting mode based on the operation of the front and rear lights when the car changes lanes to the left, right, or brakes, used to control the light-emitting component to operate in the same or similar manner when the freight bicycle is determined to be in the corresponding operating state.

[0095] Reference Figure 3 Step S200, determining the light-emitting mode of the light-emitting component based on the current operating parameters and controlling the operation of the light-emitting component, specifically includes:

[0096] Step S221: Determine the current operating state based on the current operating parameters, and determine the light-emitting mode of the light-emitting component corresponding to the current operating state;

[0097] Step S222: When determining that the freight bicycle is turning left or requesting the freight bicycle to change lanes to the left based on the current operating parameters, control the middle light-emitting part to remain constantly lit according to the set left-turn mode, and control the left light-emitting part and the second light-emitting component set on the left side near the cargo box to light up and flash.

[0098] Step S223: When determining that the freight bicycle is turning right or requesting the freight bicycle to change lanes to the right based on the current operating parameters, control the middle light-emitting part to remain on according to the set right-turn mode, and control the right light-emitting part and the second light-emitting component set on the right side near the cargo box to light up and flash.

[0099] Step S224: When the freight bicycle brakes according to the current operating parameters, control the middle light-emitting part and the two second light-emitting components to light up according to the set braking mode.

[0100] The system controls the illumination of the lighting components based on the lane-changing and braking status of the freight bicycle. Specifically, the current turning or lane-changing status of the freight bicycle is determined by the auxiliary wheel angle detected by the auxiliary wheel angle detection component and changes in the angle of the environmental image detected by the camera. Additionally, the user can input commands to request a left lane change or a right lane change by pressing user buttons or turning the handlebars. The received commands are received by the button status detection component and the communication component. When the control module determines that the freight bicycle is turning left or requests a left lane change, it controls the lighting components to operate according to the set left-turn mode; similarly, when the system determines that the freight bicycle is turning right or requests a right lane change based on current operating parameters, it controls the lighting components to operate according to the set right-turn mode.

[0101] In addition, the braking status is detected by the brake signal detection component, and the operation of the light-emitting component is controlled according to the set braking mode. This is used to indicate braking by controlling the middle light-emitting part, the two second light-emitting components to light up for a set time, or to keep them constantly lit.

[0102] It should be noted that when used to indicate the steering and braking status of freight bicycles, the color temperature of the light-emitting component, the light-emitting sequence of multiple LEDs, the light-emitting duration, and the light-emitting time interval can also be set according to actual needs. The brightness of the LEDs in the light-emitting component can also be controlled in conjunction with the battery level of the freight bicycle.

[0103] The lighting components on the freight bicycle are controlled by the bicycle's battery level. Besides serving a decorative purpose by indicating the component's operational status, this also helps reduce energy consumption. The freight bicycle also includes a battery detection component to monitor its battery level.

[0104] Reference Figure 4Step S200, determining the light-emitting mode of the light-emitting component based on the current operating parameters and controlling the operation of the light-emitting component, specifically includes:

[0105] Step S231: Determine the current operating state based on the current operating parameters, and determine the light-emitting mode of the light-emitting component corresponding to the current operating state;

[0106] Step S232: When the battery level of the freight bicycle is not less than the preset alarm battery level, control the first light-emitting component and / or the second light-emitting component to work according to the light-emitting mode corresponding to the current operating state.

[0107] Step S233: When the battery level of the freight bicycle is lower than the preset alarm battery level, control one of the two second light-emitting components to work according to the set battery alarm mode.

[0108] The system controls the illumination of the light-emitting components based on the battery level and operating status of the freight bicycle. This allows the system to automatically determine when the freight bicycle's battery level falls below a preset alarm level, enabling it to enter a power-saving mode. In this mode, some light-emitting components are controlled to operate, thus reducing energy consumption while indicating the bicycle's operating status. Generally, when controlling the light-emitting components according to a set illumination mode, the first and second light-emitting components are controlled to operate, or at least the second light-emitting component is controlled to operate, depending on the set illumination mode. In power-saving mode, at most one of the first and second light-emitting components is controlled to operate. Optionally, an alarm battery level can be preset at any value between 15% and 20%. When the alarm battery level is preset at 15%, if the freight bicycle's battery level is not less than 15%, the first and / or second light-emitting components are controlled to operate according to the illumination mode corresponding to the current operating status; if the freight bicycle's battery level is less than 15%, one of the two second light-emitting components is controlled to operate according to the set battery alarm mode.

[0109] Specifically, the technical solution of this application can also set multiple power levels corresponding to the battery level of the freight bicycle, and control the operation of the light-emitting component according to different power levels. Specifically, step S200, determining the light-emitting mode of the light-emitting component based on the current operating parameters and controlling the operation of the light-emitting component, specifically includes:

[0110] The current operating status is determined based on the current operating parameters, and the light-emitting mode of the light-emitting component corresponding to the current operating status is determined accordingly.

[0111] When the battery level of the freight bicycle is not less than 20%, the first and second light-emitting components are controlled to work according to the light-emitting mode corresponding to the current operating status.

[0112] When the battery level of the freight bicycle is less than 20% and not less than 15%, the first light-emitting component is controlled to operate at the minimum brightness of the set light-emitting mode, and the second light-emitting component is controlled to operate in the set light-emitting mode.

[0113] When the battery level of the freight bicycle is less than 15% but not less than 10%, the first light-emitting component is turned off, and one of the two second light-emitting components is controlled to operate according to the set light-emitting mode, while the other is controlled to operate according to the set battery alarm mode.

[0114] When the battery level of the freight bicycle is less than 10% and not less than 5%, the first light-emitting component is turned off, and one of the two second light-emitting components is controlled to operate at the minimum brightness of the set light-emitting mode, while the other is controlled to operate according to the set battery alarm mode.

[0115] When the battery level of the freight bicycle is less than 5%, the control shuts off the first light-emitting component and one of the two second light-emitting components, and controls the other of the two second light-emitting components to operate according to the set battery alarm mode.

[0116] The specific power alarm mode can be to control at least some of the multiple light groups of the light-emitting component to flash continuously or to flash continuously at different color temperatures. The specific working mode of the light-emitting component at different power levels of the freight bicycle can be set according to the power level of the freight bicycle, and is not limited here.

[0117] In one embodiment, the current operating state determined based on the current operating parameters includes a normal operating state and an abnormal operating state. Step S223, controlling one of the two second light-emitting components to operate according to the set power alarm mode when the battery level of the freight bicycle is lower than the preset alarm power level, specifically includes:

[0118] When the battery level of the freight bicycle is lower than the preset alarm battery level and the current working state is normal operation, the first light-emitting component is controlled to work according to the light-emitting mode corresponding to the current operating state, and one of the two second light-emitting components is controlled to work according to the set battery alarm mode while the other stops working.

[0119] When the battery level of the freight bicycle is lower than the preset alarm level and the current operating state is abnormal, the first light-emitting component is controlled to stop working, and one of the two second light-emitting components is controlled to work according to the light-emitting mode corresponding to the current operating state, and the other is controlled to work according to the set battery alarm mode.

[0120] In the embodiments of this application, corresponding operating parameters or operating parameter ranges are set according to different operating states of the freight bicycle, which are used to determine the operating state of the freight bicycle based on the acquired operating parameters. The current operating parameters include one or more combinations of operating speed, bicycle lean angle, and training wheel angle. Specifically, preset safety parameter ranges can be set for operating speed, bicycle lean angle, and training wheel angle, etc., to determine the current operating state of the freight bicycle as normal operation when all operating parameters, such as operating speed, bicycle lean angle, and training wheel angle, are within the preset safety parameter range, and to determine the current operating state of the freight bicycle as abnormal operation when any one of the operating parameters, such as operating speed, bicycle lean angle, and training wheel angle, exceeds the preset safety parameter range. The specific implementation method for determining whether the current operating state is normal or abnormal operation can be set according to actual conditions, and is not limited here.

[0121] This system controls the illumination of the light-emitting components based on the battery level and operating status of the freight bicycle. When the battery level is below a preset alarm level and the bicycle is in normal operating condition, the system automatically determines that the bicycle should enter a power-saving mode. By controlling some of the light-emitting components, it indicates the operating status of the bicycle while reducing energy consumption by the light-emitting components. Conversely, when the battery level is below the preset alarm level and the bicycle is in an abnormal operating condition, the system automatically determines a battery alarm and an abnormal operation. It stops the first light-emitting component from working, controls some of the second light-emitting components to operate according to the illumination mode corresponding to the current operating status, and controls other second light-emitting components to operate according to a set battery alarm mode. This system indicates the operating status of the freight bicycle through the light-emitting components, reduces energy consumption by the light-emitting components, and simultaneously alerts the user to stop the bicycle from operating and to inspect it, preventing abnormalities from affecting the normal operation of the freight bicycle or even causing damage and affecting its service life.

[0122] In one embodiment, the freight bicycle is equipped with an information acquisition module, a communication interface, etc., for acquiring the light emission mode. The light emission mode includes at least one or more of the following:

[0123] Acquire and store multiple light emission modes transmitted by the terminal device; the multiple light emission modes transmitted by the terminal device can be, but are not limited to, multiple light emission modes input by the user through terminal device APPs such as mobile phones, laptops, and tablets.

[0124] Acquire and store multiple lighting modes set by the user based on the input device; the input device can be, but is not limited to, multiple lighting modes set by the user through the input keyboard, buttons, touch screen, microphone, communication interface connected to external control equipment, etc. of the freight bicycle.

[0125] The system acquires and stores various state setting information set by the user based on the input device, determines and generates a light-emitting mode; the various state setting information set by the user based on the input device is used to set multiple state parameter ranges that can control the light-emitting component, and sets a light-emitting mode for each state parameter range, so as to generate the corresponding light-emitting mode when the acquired state parameters reach the set state parameter range.

[0126] It acquires and stores the light-emitting mode triggered by the current operating state; it also acquires and stores the light-emitting mode triggered by the current environmental parameters. Users can preset multiple light-emitting modes and corresponding state and environmental parameters for each mode. When the acquired state and environmental parameters reach the range that triggers the corresponding light-emitting mode, the light-emitting component can be directly controlled to work according to the set light-emitting mode.

[0127] It should be noted that the freight bicycle of this application can also control the operation of the light-emitting component in conjunction with different sound effect parameters such as ambient sound, and control sound effect devices such as speakers to emit specific sound effects when controlling the operation of the light-emitting component. Specifically, sound effect parameters for triggering the setting of different light-emitting modes are acquired and stored, and used to control the light-emitting component to operate according to the corresponding light-emitting mode when the ambient sound parameters reach the set sound effect parameters.

[0128] In one embodiment, the freight bicycle further includes an environmental detection component for detecting environmental parameters. Before performing the steps of determining the light emission mode of the light emission component based on the current operating parameters and controlling the operation of the light emission component, the ambient light control method includes the following steps:

[0129] Acquire and store multiple emission modes, as well as the range of environmental parameters used to trigger various emission modes.

[0130] This allows the lighting components to operate according to a set lighting mode, taking into account different environmental parameters, in environments with low visibility, rain, or cold weather. This enables the lighting components to display the status of the freight bicycle, helping users understand its operating status. In addition, it can further optimize the lighting decoration effect in extreme environments. By automatically adjusting the operating parameters of the lighting components based on different environmental parameters, it can also further optimize safety and prevent users from failing to notice changes in the status of the freight bicycle in a timely manner.

[0131] In some embodiments of this application, the freight bicycle also includes an environmental detection component for detecting environmental parameters. Specifically, the environmental detection component includes, but is not limited to, temperature and humidity sensors, wind speed sensors, wind direction sensors, and illuminance sensors, for detecting environmental parameters and further setting the operating mode of the light-emitting component based on the detected environmental parameters such as temperature and humidity, wind speed, wind direction, and illuminance, so as to control the light-emitting component to work according to different set light-emitting modes at different times and in different environmental scenarios.

[0132] Comparatively, cars are less affected by wind speed, ambient temperature, and humidity during operation. For example, even in high winds, a car can maintain stable operation thanks to its powerful engine and stable suspension system. From a practical standpoint, there's little need to install environmental monitoring devices in cars to detect wind speed, direction, temperature, humidity, and light intensity. Users generally don't focus on these environmental factors when buying a car, making such devices largely unnecessary. However, bicycles, especially cargo bicycles, are more susceptible to instability in strong winds due to their heavy loads and lack of protective enclosures. Monitoring environmental parameters like temperature, humidity, wind speed, direction, and light intensity with environmental monitoring devices can help cyclists plan routes effectively, avoid headwinds and other unfavorable conditions, and further improve visibility by selecting appropriate lighting modes, thus enhancing riding efficiency, comfort, and safety. The light-emitting component in this application can not only realize the car's light-emitting mode, but also control the light-emitting component to work according to different light-emitting modes at different times and in different environmental scenarios. In addition to serving as an ambient light decoration, the light-emitting component also serves as an environmental reminder. In addition to reminding the rider of the current environmental conditions, it can also be used to remind other road users in extreme weather to avoid collisions and effectively improve safety.

[0133] When the current temperature and / or humidity are determined to be too high (or too low) and / or too high (or too low) based on the current temperature and humidity, the lighting components are controlled according to the set lighting mode to indicate the current temperature and humidity by continuously flashing the first and / or second lighting components. Alternatively, a separate display screen can be set up to display the corresponding values ​​for the current temperature and humidity to alert the user. When the current wind speed and direction are determined to be too high in the current riding direction, the lighting components are controlled according to the set lighting mode to indicate the user to turn by continuously flashing the first and / or second lighting components. When the current illuminance is determined to be in a nighttime or low-light environment, the lighting components are controlled according to the set lighting mode to indicate the user to low light by continuously flashing the first and / or second lighting components. Alternatively, the first lighting component can be kept constantly lit to ensure good visibility while riding. Specific settings can be customized according to actual conditions and will not be elaborated here.

[0134] This application acquires and stores multiple light-emitting modes and the range of environmental parameters used to trigger these modes. It sets the execution order of light-emitting modes triggered by environmental parameters to precede those triggered by the freight bicycle's status parameters. Taking the detection of illuminance by a light sensor and the determination of the freight bicycle's speed based on current operating parameters as an example, when the current operating parameters determine that the freight bicycle is running at high speed, and when the current environmental parameters determine that it is in a nighttime or low-light environment, the light-emitting components are first controlled to operate in the light-emitting mode corresponding to the nighttime environment to prompt the user to enter nighttime mode. Then, the light-emitting components are controlled to operate in the light-emitting mode corresponding to the determined high-speed operation of the freight bicycle. Specific settings can be customized according to actual conditions and are not limited here.

[0135] This application primarily sets corresponding operating parameters or ranges for different operating states of freight bicycles. These parameters are used to determine the operating state of the freight bicycle and control the operation of the light-emitting components based on the light-emitting mode triggered by the current operating state. Considering that in actual operation, situations may arise where a light-emitting mode is not set for all operating parameters, or where the set light-emitting mode cannot accommodate all operating parameters—for example, when the freight bicycle is operating against the wind, and the wind speed is too high for it to operate at a speed less than 5 km / h, but the light-emitting mode is not preset for this speed—the application can combine environmental parameters and control the light-emitting components according to the light-emitting mode corresponding to the current wind speed, illuminance, and other environmental parameters.

[0136] Specifically, in one embodiment, the steps of determining the light emission mode of the light-emitting component based on the current operating parameters and controlling the operation of the light-emitting component specifically include:

[0137] When the current operating parameters are the same as the user-defined status settings, control multiple LED beads to work according to the corresponding generated or set light emission modes;

[0138] When the current operating parameters are different from the user-defined status settings, determine the range of environmental parameters that is closest to the current environmental parameters, and control the operation of the light-emitting components according to the light-emitting mode triggered by the closest parameter range.

[0139] Understandably, the user-defined status settings include the range of operating parameters and the lighting mode triggered when the current operating parameters reach the corresponding range. This allows the system to automatically control the lighting components according to the triggered lighting mode based on the acquired operating parameters. This setup allows for primary control of the freight bicycle ambient lights using the user-defined status settings, and secondary control using the corresponding lighting mode triggered by environmental parameters when the current operating parameters differ from the user-defined status settings. This demonstrates the freight bicycle's operating status by controlling the lighting components, alerting users and other road users, and enhancing the decorative effect of the lighting components.

[0140] In some embodiments of this application, when the current operating parameters differ from the user-defined state settings, it can be generally determined that the current operating state of the freight bicycle is abnormal. If the freight bicycle is in an abnormal operating state but there is no preset light-emitting mode corresponding to this abnormal operating state, controlling the light-emitting component according to environmental parameters can promptly provide feedback to the user and further optimize safety. Controlling the light-emitting component according to the light-emitting mode triggered by the environmental parameter range closest to the current environmental parameters is generally achieved by controlling a second light-emitting component to flash continuously at a corresponding speed, serving as a safety reminder. Specifically, different light-emitting modes triggered by different environmental parameter ranges can be set according to actual conditions, and are not limited here.

[0141] In addition, in some other alternative embodiments of this application, step S200, which involves determining the light emission mode of the light-emitting component based on the current operating parameters and controlling the operation of the light-emitting component, may further include:

[0142] The system determines the duration for which the freight bicycle maintains the same light-emitting mode. If the duration for which the freight bicycle maintains the same light-emitting mode has not reached the set mode adjustment time, the system controls the light-emitting component to continue working. If the duration for which the freight bicycle maintains the same light-emitting mode has reached the set mode adjustment time, the system controls the light-emitting component to work according to the set color temperature change mode.

[0143] Specifically, when the freight bicycle maintains the same light-emitting mode for a set time until the set mode adjustment time is reached, the light-emitting component is controlled to change the color temperature according to the set color temperature change mode within the set color temperature change time and then return to the original color temperature and working mode, in order to remind the user that the freight bicycle has maintained the same operating state for a long time.

[0144] It should be noted that the freight bicycle of this application can also control the operation of the light-emitting component in conjunction with different sound effect parameters such as ambient sound, and control sound devices such as speakers to emit specific sound effects when controlling the operation of the light-emitting component. Step S200, determining the light-emitting mode of the light-emitting component based on the current operating parameters, and the step of controlling the operation of the light-emitting component may further include:

[0145] When the ambient sound parameters reach the set sound effect parameters, determine the light emission mode corresponding to the sound effect parameters and control the light emission components to work;

[0146] Alternatively, based on the current operating parameters, determine the light-emitting mode of the light-emitting component, control the light-emitting component to work according to the corresponding light-emitting mode, and control the sound effect device to emit a sound effect corresponding to the light-emitting mode.

[0147] The specific implementation method of the ambient light control method for freight bicycles in this application can be further set according to actual conditions, and some of the aforementioned control methods can be adjusted and changed in combination with different actual applications, which are not limited here.

[0148] This application also proposes a freight bicycle, with reference to...

[0149] Specifically, the cargo box 110 has at least one recessed mounting groove along its periphery for mounting a light-emitting component. This application includes at least one light-emitting component. When there are multiple light-emitting components, the multiple light-emitting components include a first light-emitting component 121 and a second light-emitting component 122. The number of first light-emitting components 121 can be one, two, three, or other multiples, and the same applies to second light-emitting components 122. Specifically, the mounting groove includes a first mounting groove and a second mounting groove. The first mounting groove is located on the front side of the cargo box 110 and partially surrounds the cargo box 110, for mounting the first light-emitting component 121. The second mounting groove is located on the rear side of the cargo box 110 for mounting the second light-emitting component 122, such that the first light-emitting component 121 and the second light-emitting component 122 are arranged opposite to each other on the front and rear sides of the cargo box 110. There are two second mounting slots for mounting two second light-emitting components 122. One of the two second mounting slots is located at the turning position on the left and rear sides of the cargo box 110, and the other is located at the turning position on the right and rear sides of the cargo box 110, so that one of the two second light-emitting components 122 is located near the left side of the cargo box 110 and the other is located near the right side of the cargo box 110.

[0150] The status detection component is used to detect the operating status of the freight bicycle.

[0153] The freight bicycle is equipped with a control switch module. The switch module receives a power-on or power-off signal when triggered. The control module, upon receiving the power-on signal, controls the light-emitting component to turn on. If the control module has a preset power-on mode, it also controls the light-emitting component to operate according to the preset mode upon receiving the power-on signal. The control module also controls the light-emitting component to turn off upon receiving the power-off signal, or controls the light-emitting component to operate for a set time according to a preset power-off mode before turning it off.

[0154] And / or, the control module is used to control the activation of the lighting component after determining, based on the acquired current operating parameters, that the freight bicycle has switched from a stationary state to a moving state.
