Description

Technical Field

[0001] This invention belongs to the technical field of water recreation equipment, specifically relating to a multi-functional integrated platform for paddleboards. It is suitable for the system expansion and upgrading of inflatable and rigid paddleboards, and can be widely used in various scenarios such as water recreation, fishing, long-distance sightseeing, emergency rescue, and land transportation. Background Technology

[0002] As a mainstream water recreational device, paddleboards are widely used in leisure, fishing, and water tourism. With the diversification of user needs, adding functional modules such as propulsion power, seats, lateral floats, and land transfer wheels to ordinary paddleboards has become an industry trend.

[0003] Currently, most existing multi-functional water sports boards adopt a "single main body + scattered components" structural form. For example, Chinese utility model patent CN200520045076.2, "Multi-functional Water Sports Board," discloses a scheme that adds enclosed pontoons, longitudinal keels, masts, sails, and electric drive devices to a boat-shaped board. The pontoons, keels, and electric drive devices are all made into detachable structures. However, in this scheme, the various functional components are fixed separately at different positions on the board, lacking a unified load-bearing center, resulting in a cumbersome assembly process and long time consumption for each disassembly and assembly. Furthermore, because the battery and electric drive device are separate, the wiring is complex, and there is a lack of a unified centralized power supply and control mechanism, which cannot meet the requirements of high integration and stability for long-distance navigation.

[0004] To address the issue of land-based transportation, Chinese utility model patent CN202321899742.3, "A Multipurpose Surfboard," discloses a surfboard with omnidirectional wheels, wheels, a motor, and a propeller. Multiple grooves are created on the bottom and top of the surfboard body to accommodate hydraulic cylinders, limiting plates, and the propeller, enabling the wheels to move vertically. However, this solution requires significant modification to the surfboard body (i.e., grooving and drilling), limiting its application to customized surfboards and lacking universality. It cannot be used as an independent upgrade module for existing standard inflatable or rigid paddleboards. Furthermore, the dispersed installation of its components leads to instability on the water surface, increasing the risk of tipping over and posing a safety hazard.

[0005] In summary, existing technologies either suffer from fragmented components, poor compatibility, and a lack of a unified power supply and control center; or they require destructive modifications to the propeller body, thus losing the universality of modular upgrades. Therefore, there is an urgent need for a multi-functional integrated platform for propellers that can operate without damaging the propeller body, has a high degree of integration, and can simultaneously address power supply, control, portable transport, and navigation stability. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-functional integrated platform for paddleboards, aiming to solve the technical problems of existing paddleboards, such as fragmented functions, the need for destructive modifications to the paddleboard body, poor component compatibility, cumbersome assembly and disassembly, insufficient range, and poor balance performance. This invention, by constructing an independent, modular integrated platform body, strengthens the overall load-bearing capacity, centralized power supply, and centralized control capabilities of the platform, enabling rapid upgrades to various inflatable or rigid paddleboards without damaging the paddleboard itself.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A multi-functional integrated platform for paddleboards includes a main body detachably mounted on top of a paddleboard. The main body includes an integrated base, a battery box, and a multi-functional fixing profile. The battery box is arranged parallel to the integrated base, and the multi-functional fixing profile is fixed on top of the integrated base. The three components are detachably connected to each other and form a whole. The bottom of the battery box is provided with an integrated special connector for cooperating with the original accessory interface on the paddleboard surface to achieve the positioning and connection of the main body on the paddleboard.

[0008] Furthermore, multiple fixing holes for binding are evenly distributed on both sides of the battery box, which are used to further secure the battery box to the surface of the paddle plate with the binding strap.

[0009] Furthermore, the battery box is equipped with multiple vertical reinforcing columns evenly distributed inside to improve the box's impact and deformation resistance. A space is reserved at the top for installing a seat, and a threaded interface is pre-set at the space for fixing the seat to the top of the battery box with bolts.

[0010] Furthermore, the multifunctional fixing profile is provided with cross reinforcing ribs inside, and standardized installation grooves are provided on all four sides. The component can be flexibly positioned and locked by the engagement of the sliding nut with the standardized installation groove.

[0011] Furthermore, it also includes an adjustable bracket and a thruster. One end of the adjustable bracket is fixedly connected to the side of the integrated base, and the other end is fixedly connected to the thruster. The adjustable bracket and the thruster are symmetrically arranged relative to the two sides of the paddle plate. The adjustable bracket is an L-shaped cantilever bracket with weight reduction holes. A rotating shaft and a locking pin are transversely arranged in the middle, which are used to drive the thruster to fold, lock and unlock within a 180-degree range.

[0012] Furthermore, the thruster adopts a brushless motor pump-jet structure.

[0013] Furthermore, a wheel frame is installed on the multifunctional fixed profile. By changing the installation angle of the end of the wheel frame, the wheel frame can be switched between an unfolded and grounded state and a retracted and fitted state.

[0014] Furthermore, the multifunctional fixed profile is equipped with a balancing float to provide lateral buoyancy, thereby improving the anti-overturning performance of the paddleboard.

[0015] Furthermore, the battery box integrates multiple battery pack units and a BMS battery management system, with each battery pack unit equipped with an independent fault isolation circuit.

[0016] Furthermore, the present invention also provides a battery management method for the aforementioned paddleboard multi-functional integrated platform, comprising the following steps: the BMS battery management system monitors the working status of each group of battery pack units in real time; when the BMS battery management system detects a fault in a certain group of battery pack units, it outputs an isolation control signal; the corresponding fault isolation circuit receives the isolation control signal and disconnects to accurately isolate the damaged battery pack unit while maintaining the power supply continuity of the remaining normal battery pack units.

[0017] Compared with the prior art, the present invention has the following significant advantages: It truly achieves non-destructive upgrades and has extremely strong versatility. The main body of this invention serves as an independent modular hub, which precisely connects with the slide groove on the paddleboard and is double-fixed with straps. It can be adapted to the vast majority of inflatable and rigid standard paddleboards on the market without the need to slot, drill, or make any destructive modifications to the paddleboard body.

[0018] High integration completely solves the problem of fragmented functions. Load-bearing, power supply and control are unified in the main body. The battery box not only serves as the power source, but also as the load-bearing base of the seat and the core support of the entire platform. This avoids the problems of each component operating independently and messy wiring in traditional solutions, and significantly shortens the assembly time.

[0019] The ingenious wheel frame retraction and extension design enhances the convenience of land transport. By changing the insertion angle of the insertion mechanism, the wheel frame can be quickly retracted and extended without the need for complex hydraulic mechanisms (such as the existing technology CN202321899742.3). This ensures that the streamlined shape is not affected during navigation, and also makes it easy for a single person to transport the vehicle on land, reducing manufacturing costs and maintenance difficulty.

[0020] The reconfigurable modular battery design, combined with independent isolation circuits, can automatically achieve physical isolation when a single battery fails, while the remaining modules continue to work, completely eliminating the safety hazard of the equipment being paralyzed in the middle of the water due to a local failure.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 As shown, this embodiment provides a multi-functional integrated platform for paddleboards. The platform system includes a main body 1 as the integrated platform and multiple functional modules (such as a seat 2, a propeller 3, a balancing float 4, a wheel frame 5, etc.) that can be detached and adapted to the main body.

[0027] The core of this invention lies in its main body 1, which is an independent, modular, integrated hub for load-bearing, centralized power supply, and control. This main body 1 consists of three parts: a battery box 1-2, an integrated base 1-1, and a multi-functional fixing profile 1-3. Structurally, the battery box 1-2 is arranged parallel to the integrated base 1-1, and the multi-functional fixing profile 1-3 is fixed above the integrated base 1-1. The three parts are detachably connected by M8 stainless steel bolts, forming a unified, synergistic structure. Assembly tolerances are controlled within ±0.5mm, and waterproof sealing rings are installed at all connections to ensure an overall waterproof rating of IP68. Furthermore, through reasonable weight distribution, the post-assembly center of gravity offset is ≤2cm, with uniform distribution, ensuring balanced force on the propellers during navigation.

[0028] The battery box 1-2 is integrally injection molded from high-strength nylon material, with a preferred size of 48.5cm × 66.6cm × 78cm and a weight ≤18kg (including 4 sets of 12V / 20Ah single lithium batteries). To achieve secure installation without damaging the paddleboard, the bottom of the battery box 1-2 is integrally molded with a matching dedicated connector 7. This dedicated connector 7 is a sliding groove structure, and its design dimensions precisely match the sliding groove accessories that come with standard paddleboards on the market, allowing for direct docking and sliding assembly. Simultaneously, multiple sets of fixing holes 8 for straps are symmetrically and evenly distributed on both sides of the box. After the dedicated connector 7 is positioned, straps and tie straps are passed through the fixing holes for further securing to the paddleboard surface. This dual fixing structure of "sliding groove positioning + strap reinforcement" effectively resists the impact of complex aquatic environments.

[0029] Inside the battery box 1-2, multiple vertical reinforcing columns 9 are evenly distributed to form a regular support structure. This not only improves the overall impact resistance of the box but also allows it to directly bear the weight of a person. A standardized seat mounting space 10 is provided at the top of the battery box 1-2. The space 10 has a pre-installed threaded interface, allowing users to securely fix the seat 2 to the top of the battery box 1-2 using bolts, thus giving the battery box 1-2 the function of a "seat base".

[0030] In terms of power supply and control, the battery compartment 1-2 is equipped with a control motherboard and a BMS battery management system. The battery compartment adopts a reconfigurable modular design, with 1-4 sets of flexibly stackable and quickly replaceable battery pack units (each set provides approximately 4 hours of runtime, and 4 sets provide up to 16 hours of runtime). The BMS battery management system is equipped with four safety protection circuits: overcharge, over-discharge, overcurrent, and short circuit. It also integrates intelligent current distribution technology, which can accurately adjust the state of charge (SoC), voltage, and temperature of each module. More importantly, the battery system has fault isolation capabilities. In water sports environments (especially long-distance voyages or when far from shore), equipment faces high risks of corrosion, vibration, and capsizing. If a single cell in a traditional battery pack short-circuits or overheats, it often has to cut off the output of the entire battery pack, causing the paddleboard to instantly lose all power, which is extremely dangerous in complex waters. To address this issue, each battery pack unit in this embodiment is independently equipped with a fault isolation circuit composed of MOSFETs. The Battery Management System (BMS) monitors the operating voltage, current, and temperature of each battery cell in real time to determine if any abnormal faults have occurred (such as precursors to thermal runaway or sudden voltage drops). When an abnormal fault is detected in a battery cell, the BMS immediately outputs an isolation control signal. Upon receiving this signal, the corresponding fault isolation circuit instantly disconnects its physical connection to precisely isolate the damaged battery cell. Because it employs a parallel or flexible stacking architecture, the isolation action does not affect the conduction of other buses, thus maintaining the power supply continuity to the remaining healthy battery cells. This dynamic isolation mechanism ensures that the propellers still have the power to safely return even with partial battery damage, significantly improving the safety of long-distance voyages. More specifically, as a battery management method, its execution process includes the following steps: First, during operation, the BMS (Battery Management System) monitors the working status of each battery pack unit in real time (such as parameters like voltage, current, and temperature); second, when the BMS detects a fault in a battery pack unit (e.g., parameters exceeding a preset safety threshold), it actively outputs an isolation control signal; finally, the corresponding fault isolation circuit receives the isolation control signal and performs a disconnection action to precisely isolate the damaged battery pack unit while maintaining the power supply continuity of the remaining normal battery pack units. Furthermore, the battery boxes 1-2 also integrate a fast charging interface with a power output ≥250W, a single battery charging time ≤2 hours, and can be used as a 12V / 10A outdoor power supply interface to power other small electronic devices.

[0031] The integrated base 1-1 is made of high-strength nylon material by extrusion molding with a thickness of ≥5mm. It has internal longitudinal reinforcing ribs and an oxidized surface. Its preferred dimensions are 66.2cm×23.1cm×4.5cm.

[0032] This platform also includes an adjustable bracket 6 and a thruster 3. One end of the adjustable bracket 6 is fixedly connected to the side of the integrated base 1-1, and the other end is fixedly connected to the thruster 3. The adjustable bracket and the thruster are symmetrically arranged relative to the two sides of the paddle plate. The thruster 3 adopts a 500W vector control brushless motor pump-jet structure, which improves the propulsion efficiency by more than 55% compared with traditional thrusters, with a steering response time of only 0.4 seconds, and the brushless motor operating noise is ≤50dB. The adjustable bracket 6 is an L-shaped cantilever bracket with weight-reducing holes. A rotating shaft and locking pin are horizontally connected in the middle, which are used to drive the thruster 3 to fold, lock, and unlock within a 180-degree range. In addition, the folding arm integrates a concealed wiring structure to avoid wire wear. The volume after folding is only 1 / 3 of the unfolded state, which greatly improves the convenience of storage and transportation.

[0033] The multi-functional fixing profile 1-3 is made of high-strength aluminum alloy extrusion molding with internal cross reinforcing ribs. Its preferred dimensions are 80cm × 5.3cm × 5.3cm. Each of its four sides has evenly distributed standardized mounting grooves. Users can flexibly position and lock the components by sliding nuts into the standardized mounting grooves, such as flexibly hanging inflatable balancing floats 4, fishing rod holders, fish finder brackets, and other auxiliary items within the grooves.

[0034] The portable wheel frame 5 is mounted on the multi-functional fixed profile 1-3. Its main body is made of 304 stainless steel, and the bottom is equipped with 15cm diameter wear-resistant rubber rollers. For rapid single-person land transport, the end of the wheel frame 5 is inserted into the slot inside the multi-functional fixed profile 1-3 and locked using a sliding nut. When pushing the vehicle for transport, the wheel frame is held at a vertically downward insertion angle. When navigating in water, the user simply loosens the sliding nut, pulls out the wheel frame, changes the installation angle of the wheel frame ends on both sides (e.g., rotating to fit the main body), and then relocks it. In other words, by changing the installation angle of the wheel frame ends, the wheel frame 5 can be switched between an extended, grounded state and a retracted, flat state. The entire deployment and retraction process takes ≤10 seconds and requires no complex hydraulic lifting devices. In the extended, grounded state, the rubber rollers are suitable for various road conditions such as cement and gravel; in the retracted, flat state, the wheel frame fits tightly against the main body and does not affect the normal navigation of the equipment.

[0035] The inflatable balancing float 4 is connected to the multi-functional fixing profile 1-3, which can control the lateral tilt angle of the paddleboard to ≤30°, significantly improving the paddleboard's anti-tipping ability and providing safety for fishing and long-distance sightseeing. The seat 2 is made of PC material, weighs ≤3kg, and is connected to the top interface of the battery box 1-2 via four M6 stainless steel bolts with anti-loosening washers. It is foldable and can achieve 360° stepless rotation, with a folded thickness of ≤5cm for easy storage.

[0036] The workflow of the paddleboard multi-functional integrated platform in this embodiment is as follows: Step 1, Assembly and Fixing: Connect the main body 1 to the original accessory groove of the paddleboard through the special connector 7 at the bottom, and further tighten it with the straps, and check the overall waterproof performance; The second step is modular assembly: Based on requirements, the seat 2, balance float 4, propeller 3, and wheel frame 5 are quickly assembled using the standardized mounting grooves on the multi-functional fixing profile 1-3 and the reserved interfaces on the integrated base 1-1. The adjustable bracket 6 of the propeller 3 is unfolded and locked, and the inflatable balance float 4 is inflated to complete the installation. The third step is startup: turn on the power supply of battery pack 1-2. The BMS battery management system provides stable power to each electrical component and monitors the working status of each battery pack unit in real time. If a battery pack unit fails during navigation, the BMS outputs an isolation control signal to disconnect the corresponding fault isolation circuit to isolate the damaged unit and maintain power supply continuity. Step 4, Scene Switching and Maintenance: After use, turn off the power, fold and store the propeller 3, and lower the wheel frame 5 by changing the installation angle for pushing and transporting. Finally, separate the main body 1 from the paddles to complete the equipment storage.

[0037] The multi-functional integrated paddleboard platform of this embodiment can flexibly switch between scenarios according to usage needs. For example: In a leisure scenario, only seat 2 can be installed to enable waterborne seating and sightseeing; In a long-distance cruise scenario, propeller 3 and balancing float 4 can be installed, along with a large-capacity battery pack, to enable automatic cruise function; In a fishing scenario, rod holders and fish finders can be installed through standardized chutes, and GPS positioning modules can be used to achieve precise positioning; In a land transport scenario, propeller 3 can be folded and wheel frame 5 can be unfolded to enable easy single-person push and transport.

[0038] In summary, the integrated platform of this invention, with the battery box, integrated base, and fixing profile as its core, achieves advanced functions such as integrated power supply and control, automatic bottoming protection, rapid wheel frame retraction and extension, and faulty battery isolation through ingenious mechanical and electronic linkage design, without damaging the original structure of the paddleboard. This platform completely changes the previous situation of paddleboard accessories being "fragmented, fragile, and cumbersome," and has extremely high value for widespread application.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
