Description

Technical Field

[0001] This invention relates to the field of electric vehicles, and more particularly to a multi-functional electric camping vehicle and its mode switching method. Background Technology

[0002] With the increasing popularity of outdoor camping, short-distance leisure travel, and light cargo transportation, electric camping vehicles, as a convenient mobile vehicle, are finding increasingly diverse and complex applications. Users not only need them to carry people and cargo on smooth roads, but also often face complex environments such as rugged trails and narrow campsites. In these situations, there is a clear demand for features such as hand-held assist, intelligent following, or remote control.

[0003] Currently, most electric camping vehicles and related portable electric vehicles on the market have relatively simple functional designs. For example, existing portable folding electric camping vehicles mainly focus on structural compactness and basic cargo-carrying functions. Their electronic control systems typically only offer a direct control mode similar to an electric scooter, where forward and backward movement is achieved through manual control of acceleration and braking. While such designs are feasible in specific scenarios, they lack specialized modes and intelligent control logic for complex road conditions (such as those requiring hand assistance to overcome obstacles) or hands-free operation (such as intelligent following and carrying). Therefore, existing electric camping vehicles generally suffer from limited functional modes and an inability to intelligently adapt to diverse usage scenarios and real-time user needs, thus restricting their practicality and user experience across all scenarios.

[0004] Therefore, the market urgently needs an electric camping vehicle that can flexibly adapt to various usage modes to cope with different road conditions and mission requirements. Summary of the Invention

S44, the execution result of the adjustment strategy is integrated with the current vehicle status into status update information, and fed back to the remote control or user interface through the wireless communication module.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: Combination Figures 1 to 4 As shown, this embodiment of the invention provides a multi-functional electric camping vehicle, including: a vehicle body 1, a drive unit 2, a control component 3, a control module and a sensor module 4; wherein the sensor module 4 includes a camera for acquiring scene information.

[0025] The vehicle body 1 is used to carry the load and the user; the drive unit 2 is installed on the vehicle body 1 and is used to drive the electric campervan to move; the control component 3 is installed on the vehicle body 1 and includes at least an ignition controller 5 for driving mode, an extension armrest and start trigger button 6 for hand-held mode, and a remote control for remote control mode; the control module is installed inside the vehicle body 1 and is electrically connected to the drive unit 2 and the control component 3, and is used to perform switching and control of driving mode, hand-held mode, follow mode and remote control mode; wherein, the control module is configured to: receive the mode switching command input by the button, and generate a mode switching enable signal according to the mode switching command; and switch between driving mode, hand-held mode, follow mode and remote control mode based on the mode switching enable signal.

[0026] Sensor module 4 is electrically connected to the control module and includes a target tracking sensor for implementing follow mode and a wireless communication module for implementing remote control mode.

[0027] The working principle of this invention is as follows: based on the user-selected driving, manual assistance, following, or remote control mode, the control module receives instructions from the control component 3 or sensor module 4, and then controls the drive device 2 to perform corresponding forward, backward, steering, or following actions, achieving full-scene coverage from cargo driving and manual assistance on complex roads to intelligent following and remote control; by integrating multiple operating modes and corresponding sensors and control units, an electric campervan can flexibly adapt to various usage scenarios such as driving with cargo, manual assistance on complex roads, intelligent following, and remote control, significantly improving the convenience and functionality of outdoor use; its intelligent mode switching and control system reduces the difficulty of user operation, enhances adaptability and practicality in different environments, and improves the stability and safety of cargo transportation.

[0028] In the driving mode, the drive unit is controlled to perform driving actions based on the input of the accelerator switch; in the hand-held mode, the drive unit is controlled to perform hand-held assist actions based on the input of the start trigger button; in the follow mode, the drive unit is controlled to perform follow driving actions based on the tracking signal of the target tracking sensor; in the remote control mode, the remote control command of the remote control is received through the wireless communication module, and the drive unit is controlled to perform the corresponding driving control actions; and based on the terrain undulations and obstacle information detected by the ultrasonic sensor array, the current operating mode or the output of the drive unit is adjusted, and the current mode status information is output to the display instrument.

[0029] In this embodiment, a pedal assembly 7 is provided at one end of the vehicle body 1, and a front assembly 8 is provided between the two pedal assemblies 7. The front assembly 8 includes a support frame 9 arranged in a vertical direction and a linkage shaft 10 arranged through the support frame 9. A receiving cavity 11 is provided in the middle of the support frame 9. The multi-functional electric camping vehicle also includes a power supply assembly 12 that supplies power to the drive device 2 and the control module. The power supply assembly 12 is disposed in the receiving cavity 11.

[0030] It should be noted that the pedal assembly 7 at the front of the vehicle body 1, together with the front assembly 8, constitutes the basic structure for the user to stand and control the vehicle. The front assembly 8 is provided with structural rigidity by a vertically mounted support frame 9, through which a linkage shaft 10 is responsible for transmitting steering and braking inputs. The power supply assembly 12 is centrally located in the cavity 11 in the middle of the support frame 9, and is directly connected to the drive unit 2 and the control module via internal cables. This layout concentrates the main weight of the vehicle near the front axle, effectively optimizing the longitudinal weight distribution of the entire vehicle.

[0031] Its beneficial effects are: it reduces the pitch and roll tendency of the vehicle when carrying loads or turning, thus improving driving stability; at the same time, the centralized arrangement of the power supply makes the electrical connection simpler and more reliable, and facilitates quick disassembly, charging or replacement, significantly enhancing the convenience and maintainability of use.

[0032] In this embodiment, a handle assembly 13 is provided at the upper end of the support frame 9, and a brake assembly 14 is provided on the handle assembly 13. The brake assembly 14 is connected to the wheel assembly of the drive device 2 through the linkage shaft 10 for braking. The handle assembly 13 is also provided with a button for mode switching or control, and a display instrument 15 for displaying vehicle speed, battery level or mode status is provided in the middle of the handle assembly 13.

[0033] The handlebar assembly 13 at the upper end of the support frame 9 serves as the core human-machine interface, integrating braking, mode control, and status display functions. Users can directly issue mode switching commands via physical buttons on the handlebar, and the control module will switch the corresponding control logic such as driving, hand-held, following, or remote control accordingly. The brake assembly 14 mechanically transmits braking force to the wheels through the linkage shaft 10, ensuring direct and reliable braking response. The display instrument 15 located in the middle of the handlebar assembly 13 continuously obtains data from the control module and displays key information such as vehicle speed, remaining battery power, and current mode in real time.

[0034] In this embodiment, it is further explained that a mounting plate 16 is provided between the handle assembly 13 and the support frame 9. The mounting plate 16 is rotatably connected to the armrest assembly 18 via a pivot 17 and a bearing. One end of the armrest assembly 18 is provided with a handhold 19 for the user to hold, and a start trigger button 6 is provided on the handhold 19.

[0035] By adding a mounting plate 16 between the handle assembly 13 and the support frame 9, and connecting the handrail assembly 18 to the bearing via a pivot 17, the handrail can rotate flexibly around its vertical axis to accommodate users of different heights and standing positions. The start trigger button 6 on the handgrip 19 is electrically connected to the control assembly 3; when the user grips and presses it, it triggers a forward or backward command in handrail mode. This design achieves multi-angle adaptive adjustment of the handrail, improving the naturalness and comfort of handrail operation. Simultaneously, integrating key control buttons into the handgrip 19 facilitates quick and safe starting and stopping of the vehicle during pushing, enhancing ease of operation in complex road conditions.

[0036] In this embodiment, the sensor module 4 further includes an ultrasonic sensor array disposed at the bottom of the vehicle body 1, which is used to detect terrain undulations and obstacles in the direction of travel.

[0037] It should be noted that the ultrasonic sensor array located at the bottom of the vehicle body 1 continuously emits and receives ultrasonic signals forward. By calculating the echo time difference, it constructs the terrain contour ahead in real time, identifying road slopes, potholes, and obstacles. This terrain data is fed back to the control module in real time to assist in decision-making, recommend driving modes, adjust driving strategies, or issue warnings to the user. This design enables the vehicle to have active environmental perception capabilities, enhancing driving safety and scene adaptability in complex road conditions, and providing key data support for intelligent mode switching.

[0038] As an optional solution in this embodiment, the target tracking sensor is an ultra-wideband (UWB) positioning module and / or a visual recognition module, used to identify and track the user or a preset target in follow mode.

[0039] It should be noted that the target tracking sensor can employ an ultra-wideband (UWB) positioning module and / or a visual recognition module: the UWB module achieves accurate distance and direction tracking by measuring the time-of-flight of the wireless signal between the target and the tag worn by the user, and is suitable for environments with obstructed vision or low light; the visual module achieves visual tracking by capturing and recognizing user features through a camera. Both can work independently or in conjunction, continuously transmitting the target's location information to the control module to control the vehicle to maintain a preset distance and trajectory.

[0040] In this embodiment, the power supply assembly 12 is a detachable lithium battery module. The side wall of the accommodating cavity 11 is provided with locking buckles and heat dissipation fins. The lithium battery module is fixed in the accommodating cavity 11 by the locking buckles and passively dissipated by the heat dissipation fins.

[0041] The power assembly 12 adopts a modular design with a detachable lithium battery module. It is quickly installed and secured via locking clips on the side wall of the accommodating cavity 11, ensuring it remains secure during driving. The heat dissipation fins on the cavity side wall increase the contact area and utilize airflow during driving to passively dissipate heat from the battery, preventing overheating. This design allows the battery to be easily removed for charging, replacement, or storage, solving the problem of inconvenient outdoor charging. Simultaneously, the heat dissipation structure improves the battery's operational stability and lifespan under high loads.

[0042] Example 2: The present invention also provides a mode switching method for a multi-functional electric campervan, applicable to a multi-functional electric campervan as described in Embodiment 1. The mode switching method includes: S1, acquire the current attitude data of the electric campervan's cargo platform and the terrain data around the vehicle; The system acquires key data in two dimensions in real time through the onboard sensor module 4: first, the current tilt and offset of the cargo platform; and second, terrain information such as the vehicle's direction of travel and the undulations and obstacle distribution of the surrounding terrain. This step forms the data foundation of the entire intelligent mode switching method, aiming to comprehensively and in real time grasp the vehicle's own status and the external environment.

[0043] S2 levels the cargo platform based on the current attitude data and evaluates the current usage scenario based on terrain data to generate scenario mode recommendations that include at least intelligent follow mode and enhanced hand-holding mode.

[0044] The system first determines whether the platform is in a stable horizontal state based on the acquired attitude data. If the level exceeds a threshold, the control module drives an adjustment mechanism (such as an independent electric push rod or other leveling compensation mechanism) to automatically level it. Simultaneously, the system analyzes the acquired terrain data, combining features such as slope and obstacle density, to evaluate and classify the current usage scenario (such as flat roads, rugged surfaces, narrow spaces, etc.). Finally, based on the scenario evaluation results, the system intelligently generates a list of one or more recommended modes, including "intelligent follow mode" and "enhanced hand-holding mode," and prompts the user to select one through the human-machine interface.

[0045] S3 responds to the user's selection command for scene mode recommendation, executes the corresponding mode switching operation, and controls the auxiliary structure of the electric campervan to make corresponding adjustments. The control module performs the corresponding mode switching operation: loading the control algorithm corresponding to the mode and adjusting the power output logic of drive unit 2. Simultaneously, the system will adaptively adjust the relevant auxiliary structures based on the selected mode and the terrain assessment results of stage S2. For example, if the enhanced handrail mode is selected and the terrain is complex, the omnidirectional auxiliary wheels may be automatically lowered to improve stability.

[0046] S4 continuously monitors attitude and terrain data during mode operation and dynamically adjusts the current operating mode and auxiliary structures based on the monitoring data.

[0047] During selected operation, the system continuously monitors data in stages, forming a closed-loop feedback loop. By analyzing real-time attitude and terrain data, the system can promptly identify abnormal changes in the operating status, such as the platform becoming unbalanced due to load movement or the appearance of new obstacles ahead. Based on this real-time data, the control module dynamically adjusts the parameters of the current operating mode (such as following distance and hand assist level) or the status of auxiliary structures (such as fine-tuning the support force of the auxiliary wheels), and triggers mode switching or safety pause when necessary.

[0048] In this embodiment, step S3 specifically includes: S31 receives and parses the selection command entered by the user on the user interface, determines the target switching mode, and generates the corresponding mode switching enable signal.

[0049] The system receives the user's selection of the recommended mode through the user interface (such as a touch screen or physical buttons), and converts the user's physical or touch input into a recognizable electrical signal. The control module analyzes the signal, accurately determines the target switching mode (such as intelligent follow or enhanced hand support) corresponding to the user's intention, and generates a clear enable signal bound to the target mode, thus realizing the accurate and rapid conversion of user intention into machine instructions.

[0050] S32, according to the mode switching enable signal, activate the control logic corresponding to the target switching mode. If the target switching mode is the intelligent following mode, start the target tracking sensor and enter the waiting state. If the target switching mode is the enhanced handrail mode, enable the control authority of the extended handrail and preload the corresponding assist curve.

[0051] The system invokes and activates a pre-stored control algorithm program that matches the target mode. If the target is in intelligent follow mode, the target tracking sensor (such as a UWB module) is activated and put into a low-power listening state to prepare for target identification and tracking. If the target is in enhanced handrail mode, the control permissions of the buttons on the extended handrail are unlocked, and the corresponding motor assist curve is pre-loaded from memory based on typical load and road surface parameters. This enables on-demand and rapid configuration of hardware and software resources, reduces response waiting time after mode switching, and optimizes the initial handling feel and follow response speed through a pre-loading strategy.

[0052] S33, combined with terrain data, links to control the auxiliary structure: if switched to enhanced hand-holding mode and the presence of undulating obstacles on the ground is detected, the adjustable omnidirectional auxiliary wheels are controlled to descend to the ground to provide auxiliary support; It should be noted that while switching modes, the system retrieves the generated terrain data and, in conjunction with the currently selected target mode, decides whether to adjust the auxiliary structure. For example, when switching to the enhanced hand-holding mode and the terrain report shows significant undulations or obstacles on the ground, the system controls the retractable omnidirectional auxiliary wheels mounted on vehicle body 1 to extend downwards and ground, providing additional lateral support and steering assistance, thus achieving coordinated optimization of the operating mode and physical structure.

[0053] S34 sends a mode switching completion status signal to the user interface and display instrument 15, indicating to the user that the electric campervan has entered the target switching mode and is ready to be operated. This provides the user with clear and intuitive visual feedback, ensuring that the user knows the vehicle is ready and can safely begin following or hand-held operations, improving the clarity of human-machine interaction and the safety of use.

[0054] In this embodiment, step S4 specifically includes: S41, acquire terrain update data collected in real time by ultrasonic sensor array, and receive remote control commands or follow status signals through wireless communication module to form operating environment dataset; S42 analyzes the operating environment dataset, determines whether there are new obstacles or terrain changes on the current path, assesses the continuity and stability of remote control or follow commands, and generates an environmental change assessment signal. S43 dynamically executes adjustment strategies based on environmental change assessment signals and the current operating mode: if a path obstacle or unstable signal is detected in follow mode, it automatically switches to low-speed driving or issues a warning; if a continuous interruption of commands is detected in remote control mode, it controls the vehicle to perform a slow stop. S44 integrates the execution result of the adjustment strategy with the current vehicle status into status update information, and feeds it back to the remote control or user interface through the wireless communication module.

[0055] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
