go-karts

Abstract

This utility model discloses a go-kart, relating to the field of go-kart technology. The go-kart includes a hull and an outer shell, connected by an upper and lower hull plate. The upper hull plate forms a passenger cabin, which includes a main seat. A windshield on the outer shell covers part of the passenger cabin and also houses a steering wheel, allowing users to easily operate the steering wheel from inside the cabin to control the go-kart's direction. Because a sealed cavity is formed between the upper and lower hull plates, extending from the bow to the stern, the go-kart utilizes this sealed cavity to generate sufficient buoyancy, ensuring stable floating on the water. Even in the event of an accidental capsizing, the sealed cavity reduces water ingress compared to foam-filled cabins, effectively preventing sinking and improving safety.

Description

Technical Field

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] In existing technology, the hull of a go-kart is filled with foam material at the bottom. When the boat capsizes, the foam absorbs water and the buoyancy drops sharply, which significantly increases the risk of sinking after the cabin is flooded.

[0037] To solve the above problems, refer to Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this utility model, the go-kart 1000 includes a hull 100 and an outer shell 200. The hull 100 includes an upper hull plate 110 and a lower hull plate 120 connected to each other. The upper hull plate 110 is recessed to form a passenger cabin 130, and the passenger cabin 130 is provided with a main seat 150. The outer shell 200 is connected to the hull 100 and includes a windshield 210. The windshield 210 covers part of the upper portion of the passenger cabin 130, and a steering wheel 220 is provided on the side of the windshield 210 facing the main seat 150. A sealed cavity 140 is formed between the upper hull plate 110 and the lower hull plate 120, and the sealed cavity 140 extends from the bow of the hull 100 to the stern of the hull 100. It should be noted that... Figure 3 To facilitate understanding of the structure of the sealed cavity 140, irrelevant lines inside the sealed cavity 140 have been removed.

[0038] The upper hull plate 110 refers to the sheet metal assembly constituting the upper structure of the hull 100. It can be formed into a curved shape using rotational molding, with its recessed areas creating a cabin space for passengers. The lower hull plate 120 refers to the sheet metal assembly constituting the bottom structure of the hull 100. For example, both the upper hull plate 110 and the lower hull plate 120 are made of high-density polyethylene, and the lower hull plate 120 is connected to the upper hull plate 110 at their edges to form a closed structure. The sealed cavity 140 refers to the sealed space formed after the upper and lower hull plates 120 are connected. For example, the upper hull plate 110 and the lower hull plate 120 can be integrally formed using rotational molding, thus forming a sealed cavity 140 between them. This cavity is distributed longitudinally along the hull 100 to provide continuous buoyancy. The windshield 210 refers to the protective structure installed on the hull 100, covering the front area of ​​the passenger cabin 130 to form a semi-open driving space.

[0039] For example, the upper deck 110 is molded to form a recessed passenger compartment 130 structure, with the main seat 150 fixedly installed inside. A continuous cavity formed between the lower deck 120 and the upper deck 110 provides buoyancy, replacing traditional foam padding. The outer shell 200 assembly is bolted to the edge of the upper deck 110, and a windshield 210 at its front protects the occupants. The steering wheel 220 is connected to the propeller 300 at the stern of the hull 100 via a steering column, allowing the driver to control the vessel's direction while protected by the windshield 210.

[0040] This design utilizes the hull 100's own structure to form a sealed cavity 140, maintaining stable buoyancy even in the event of capsizing, effectively improving the hull 100's anti-sinking performance. In the event of capsizing, the cavity structure prevents water from rapidly entering the compartments, maintaining sufficient buoyancy to keep the hull 100 afloat. The integrated design of the sealed cavity 140 and the hull 100 structure eliminates the need for additional buoyancy materials, simplifying the manufacturing process while improving structural reliability. The combined design of the windshield 210 and steering wheel 220 ensures ease of operation while enhancing driving safety, creating a water recreation tool that balances functionality and safety.

[0041] In this embodiment of the invention, the upper hull plate 110 and the lower hull plate 120 are integrally formed, for example, by rotational molding. The rotational molding process integrates the upper hull plate 110 and the lower hull plate 120 into a single structure, which can be achieved by rotating, heating, and cooling within a mold. This process eliminates seams caused by traditional splicing or bonding, preventing water ingress into cavities due to poor sealing at the seams, while simultaneously improving the overall structural strength of the hull 100.

[0042] For example, by integrally molding the upper hull plate 110 and the lower hull plate 120, a continuous and sealed cavity structure is formed inside the hull 100. This cavity provides buoyancy without the need for additional foam filling, and the cavity walls have no seams, effectively preventing external water from seeping in. During the rotational molding process, the material is evenly distributed on the inner wall of the mold, and after cooling, a hull 100 structure of uniform thickness is formed, further ensuring the integrity of the sealed cavity 140. This solution uses an integral molding process, completely eliminating seam defects, making the hull 100 structure more reliable, while simplifying the manufacturing process and reducing the risk of sinking due to poor sealing. This embodiment can provide stable buoyancy using an integrally molded sealed cavity without relying on foam filling, avoiding insufficient buoyancy caused by water seepage at the hull 100 seams, thereby improving the safety and service life of the go-kart 1000.

[0043] Reference Figure 2 and Figure 3 As shown in the embodiment of this utility model, the upper deck 110 is recessed below the main seat 150 to form a first storage cavity 111. The seat cushion of the main seat 150 and the outer shell 200 are rotatably connected. The seat cushion of the main seat 150 is configured to open or close the first storage cavity 111. The first storage cavity 111 refers to the internal space formed by the recess of the upper deck 110. It can be achieved by forming a groove structure on the surface of the upper deck 110 using a rotational molding process. This structure is used to store items such as life jackets and tools, avoiding additional occupation of the external space of the hull 100. The rotatable connection refers to the rotatable fixing method between the seat cushion and the outer shell 200 through a hinge or pivot. It can be achieved by using a stainless steel hinge and bolts for fixing, which allows the user to quickly open or close the storage cavity by flipping the seat cushion. Opening or closing refers to the action of the seat cushion covering or exposing the opening of the first storage cavity 111 after rotating around the rotatable connection point. This can be achieved by setting a buckle or magnetic device on the edge of the seat cushion to ensure that the seat cushion remains sealed with the upper deck 110 when closed.

[0044] For example, the seat cushion of the main seat 150 is connected to the side wall of the outer shell 200 via a hinge, or the seat cushion of the main seat 150 is rotatably connected to the bracket 260 via a hinge. When the user lifts the seat cushion upwards, the opening of the first storage compartment 111 is fully exposed, facilitating the insertion or removal of items; when the seat cushion is flipped downwards, its edge fits against the upper deck 110, sealing the opening of the storage compartment. The recessed depth of the first storage compartment 111 can be set to match the thickness of the seat cushion, ensuring that the seat cushion is flush with the surface of the upper deck 110 after closing, avoiding any impact on seating comfort. This solution, by forming a storage compartment directly under the main seat 150, utilizes the redundant space inside the hull 100 and achieves sealing protection through the seat cushion opening and closing structure, while avoiding the reduction of buoyancy caused by adding extra external structures to the hull 100. This solution can provide enclosed storage within the limited space of the hull 100, reducing the structural complexity caused by external storage devices, while maintaining the airtightness of the hull 100 cavity, avoiding the impact on buoyancy distribution due to the addition of external storage structures, and reducing the risk of sinking.

[0045] Reference Figure 1 As shown in the embodiment of this utility model, a secondary seat 160 is provided between the stern of the hull 100 and the main seat 150. The secondary seat 160 refers to a seat for passengers other than the user of the main seat 150, and can be implemented with the same or similar structure as the main seat 150, for example, by bolting or welding it to the stern area of ​​the hull 100. The seat is located behind the main seat 150, so that the interior space of the hull 100 is divided into two seating areas, front and rear.

[0046] For example, the main seat 150 is located in the middle of the hull 100, and the secondary seat 160 is located behind it near the stern, with an appropriate gap between them to avoid restricting legroom for users. The width and depth of the stern region of the hull 100 can be designed to match the area of ​​the main seat 150, for example, by forming a mounting base for the secondary seat 160 through a recess in the upper hull plate 110, or by directly fixing the seat bracket 260 to the surface of the lower hull plate 120. With this layout, the interior of the hull 100 can simultaneously accommodate users of the main and secondary seats 160, without significantly increasing the overall size of the hull 100, thereby increasing passenger capacity while maintaining the original buoyancy performance.

[0047] This design, by longitudinally arranging the main and auxiliary seats 160, allows for front and rear seating while maintaining a compact structure in the hull 100. It is particularly suitable for scenarios requiring parental accompaniment of children or two-person cooperative driving, expanding usability while avoiding increased drag or decreased handling stability caused by widening the hull 100 laterally. This design solves the problem of insufficient passenger capacity in traditional go-karts 1000, adding extra seats within the limited space of the hull 100, improving the feasibility of multi-person collaborative entertainment, and avoiding buoyancy imbalance or increased drag caused by enlarging the hull 100's size, thus balancing safety and practicality.

[0048] Reference Figure 2 and Figure 3 As shown, in an embodiment of this utility model, the upper deck 110 is recessed below the passenger seat 160 to form a second storage cavity 112. (Refer to...) Figure 4 As shown, the go-kart 1000 also includes a bracket 260, which is fixedly connected to the outer shell 200. The cushion of the secondary seat 160 is rotatably connected to the bracket 260, and the cushion of the secondary seat 160 is configured to open or close the second storage compartment 112.

[0049] The second storage compartment 112 is a recessed space located below the passenger seat 160. It can be created by stamping or injection molding to form a groove on the surface of the upper deck 110, and is used to store items such as life jackets and tools. The bracket 260 is a rigid structure supporting the seat cushion of the passenger seat 160. It can be made by welding or bolting a metal rod or plastic frame to the outer shell 200, providing a fulcrum for the cushion's rotation. The swivel connection refers to a mechanical connection between the cushion and the bracket 260 that allows rotation around an axis. This can be achieved using a hinge or pivot structure, allowing the cushion to rotate around a fixed axis to open or close the second storage compartment 112. For example... Figure 4 The seat cushion of the secondary seat 160 is rotatably connected to the bracket 260 via a connecting rod, and can rotate around the rotation center 261 on the bracket 260.

[0050] For example, the seat cushion of the secondary seat 160 is connected to the bracket 260 via a hinge. When it is necessary to access items in the second storage compartment 112, the seat cushion can be flipped upwards to expose the storage compartment opening. After the operation is completed, the seat cushion can be reset to close the opening. The bracket 260 is fixed to the back panel 250 area of ​​the housing 200 and is kept stable by bolts or welding to ensure the reliability of the seat cushion opening and closing process. The depth and shape of the second storage compartment 112 can be adjusted according to actual needs, for example, using a rectangular or arc-shaped profile to accommodate the size of different items.

[0051] This solution creates a recessed second storage cavity 112 directly on the upper deck 110 and closes it using a seat cushion opening and closing structure. This saves space for additional storage boxes and avoids adding weight to the hull 100 with external components. It solves the problem of inconvenience for users to store their personal belongings. At the same time, the rotating connection design between the seat cushion and the bracket 260 makes opening the storage cavity more convenient without affecting the sealing and overall stability of the hull 100 structure.

[0052] Reference Figure 5 As shown in the embodiment of this utility model, the outer shell 200 includes a first support plate 230, a second support plate 240, and a back plate 250. The first support plate 230 is disposed below the main seat 150, and the second support plate 240 is disposed below the secondary seat 160. The height of the second support plate 240 is higher than that of the first support plate 230. The back plate 250 is inclined and connected between the first support plate 230 and the second support plate 240. The backrest 151 of the main seat 150 is connected to the back plate 250, and the bracket 260 is fixedly connected to the back plate 250.

[0053] The first support plate 230 is a plate-like structure located below the main seat 150 to support its weight. It can be made of plastic injection molding and its function is to provide a stable support base for the main seat 150. The second support plate 240 is a plate-like structure located below the secondary seat 160 and higher than the first support plate 230. It can be made of the same material as the first support plate 230 and has a stepped structure. Its function is to create a stepped layout through the height difference to adapt to the installation requirements of different seats. The backrest 250 is a transition structure that is inclined between the first support plate 230 and the second support plate 240. Its function is to provide an ergonomic support surface for the seat back 151 through the inclined angle.

[0054] For example, the backrest 151 of the main seat 150 is bolted to the inclined backrest 250, allowing the user's back to conform to the inclination angle of the backrest 250 when seated. The second support plate 240 is set higher than the first support plate 230, forming a stepped layout, creating a height difference between the secondary seat 160 and the main seat 150, preventing interference between the users' legroom. The bracket 260 is fixed to the backrest 250 by welding or riveting, providing a rigid support point for the flipping movement of the secondary seat 160 cushion.

[0055] This solution achieves a three-dimensional seating layout within the limited space of the hull 100 by combining a stepped support plate and an inclined back panel 250. This effectively solves the problem of low space utilization in the seat support structure of the two-person go-kart 1000. The main and secondary seats 160 are staggered through the stepped support plate to avoid overlapping legroom for users. The inclined back panel 250 provides a support angle for the main seat 150 that conforms to the human body curve, and also serves as the mounting carrier for the bracket 260, making the flipping action of the secondary seat 160 cushion more stable and reliable.

[0056] Reference Figure 6 As shown in the embodiment of this utility model, along the width direction of the go-kart 1000, the outer shell 200 forms placement areas 270 on both sides of the main seat 150. These placement areas 270 are configured to provide footrests for the user in the secondary seat 160. The placement areas 270 refer to the spatial areas formed by the outer shell 200 structure on both sides of the main seat 150. These can be implemented using outwardly extending support plates or recessed structures, providing footrest space for the user in the secondary seat 160 and preventing instability caused by dangling legs. The footrests in the secondary seat 160 refer to the footrest position for the passenger in the secondary seat 160. This can be achieved by providing horizontal or inclined support surfaces on both sides of the main seat 150. This optimizes the spatial layout, providing stable foot support for the user in the secondary seat 160 within the limited space of the hull 100, thus improving riding comfort.

[0057] For example, the outer shell 200 extends outward on both sides of the main seat 150 to form symmetrical support areas, creating recesses or platforms for foot placement between these areas and the main seat 150. When the user of the secondary seat 160 is seated, their feet can naturally extend to the placement areas 270 on both sides of the main seat 150, preventing legs from being cramped or dangling due to the narrow space of the hull 100. This structure achieves foot support without increasing the width of the hull 100 by making reasonable use of the redundant space on both sides of the main seat 150, while maintaining the streamlined structure of the hull 100 to reduce drag. This solution solves the problem of discomfort caused by lack of foot support for the user of the secondary seat 160, improves comfort when multiple users are seated together by optimizing the spatial layout of the hull 100, and maintains the compactness and mobility of the hull 100 structure.

[0058] Reference Figure 2As shown in the embodiment of this utility model, the upper ship plate 110 is recessed to form multiple mounting grooves 113. These mounting grooves 113 are spaced apart along the edge of the upper ship plate 110. Nuts are provided within the mounting grooves 113, and the outer shell 200 is bolted to the nuts for fixed connection to the upper ship plate 110. The mounting groove 113 refers to a groove-like structure formed by inward recesses on the surface of the upper ship plate 110, which can be achieved using stamping or rotational molding processes. It is used to accommodate the nuts and restrict their displacement. The nuts can be fixed in the mounting grooves 113 by pre-embedding or welding, forming a detachable mechanical connection with the bolts.

[0059] For example, the edge region of the upper hull plate 110 has recessed areas forming multiple spaced mounting grooves 113, each containing a nut. The outer casing 200 is connected to the hull 100 via bolts and nuts threaded together. The recessed structure of the mounting grooves 113 allows the nuts to embed inside the hull 100, preventing bolts from penetrating the hull 100 and damaging the sealing cavity 140. For instance, the mounting grooves 113 are evenly distributed along the edge of the hull 100, which can distribute the stress at the connection points of the outer casing 200 while maintaining the flatness of the hull 100 surface.

[0060] This solution utilizes a recessed mounting groove 113 with an embedded nut to ensure connection strength while preventing penetration of the hull 100, effectively protecting the integrity of the sealed cavity 140. Simultaneously, it achieves a stable connection between the outer shell 200 and the hull 100, preventing a decrease in buoyancy due to damage to the sealed cavity 140 caused by the connection structure. The layout of the mounting groove 113 with the embedded nut can adapt to the assembly requirements of different outer shell 200 shapes, while avoiding a reduction in structural strength on the hull 100 surface due to openings, thus improving the overall safety and service life of the hull 100.

[0061] Reference Figure 7 As shown in the embodiment of this utility model, the lower hull plate 120 protrudes along the side opposite to the upper hull plate 110 to form a water-dividing rib 121. The water-dividing rib 121 extends along the length direction of the go-kart 1000, and multiple water-dividing ribs 121 are provided and spaced apart along the width direction of the go-kart 1000. The water-dividing rib 121 refers to a longitudinal strip-shaped structure protruding from the bottom surface of the lower hull plate 120, which can be implemented by continuous protruding ribs with trapezoidal or arc-shaped cross sections. The water-dividing ribs 121 can be arranged in an equidistant or gradually varying spacing manner. The extension direction of the water-dividing ribs 121 is parallel to the longitudinal axis of the hull 100, and a tapering tail structure can be provided in the bow area.

[0062] For example, the water-dividing ribs 121, by forming longitudinally arranged protrusions on the bottom surface of the lower hull plate 120, effectively divide the water flow when the ship is moving. When the water flows over the hull bottom, the water-dividing ribs 121 divide the continuous water flow into multiple independent flow channels, reducing the vortex resistance generated by the lateral movement of the water flow. The longitudinal extension of the water-dividing ribs 121 ensures that the water flow division effect covers the entire hull bottom area, while the spaced arrangement in the width direction forms regular water flow channels while ensuring structural strength. When the hull 100 turns, the water-dividing ribs 121 can also generate a directional water flow resistance difference, helping to improve turning stability.

[0063] Through the above technical solution, this solution can significantly improve the hydrodynamic performance of the go-kart 1000. The water-dividing rib 121 structure continuously generates lift during movement, helping to maintain the buoyancy stability of the hull 100. The guiding effect of the water-dividing rib 121 can reduce the probability of sideslip during turning, and the composite flow channel formed by multiple water-dividing ribs 121 can also suppress the roll amplitude of the hull 100, maintaining a stable driving attitude in a wave environment. This structure achieves the dual effects of reducing drag and increasing buoyancy without increasing the volume of the hull 100, by optimizing the bottom shape.

[0064] Reference Figure 1 As shown in the embodiment of this utility model, the hull 100 protrudes outward on both sides along the width direction to form a water pressure plate 122. The inner cavity of the water pressure plate 122 is connected to the sealed cavity 140. The water pressure plate 122 is provided with a flow guide slope 123 at the bow end facing the go-kart 1000. The flow guide slope 123 extends obliquely from top to bottom along the direction away from the bow of the go-kart 1000.

[0065] The ballast plate 122 refers to the plate-like structure protruding outward from both sides of the hull 100. It can be implemented by using an arc-shaped shell integrally formed with the hull 100. Its internal cavity is connected to the sealed cavity 140 of the hull 100 to form a continuous airtight space. The guide slope 123 refers to the downward-sloping plane at the front end of the ballast plate 122. It can be implemented by the inclined surface or curved transition structure of the leading edge of the ballast plate 122, and is used to guide the water flow along the inclined direction.

[0066] For example, the ballast plate 122 expands the width of the hull 100 by protruding outward, increasing the displacement volume and thus enhancing buoyancy; its inner cavity is connected to the sealed cavity 140, forming a closed air layer inside the ballast plate 122, further reducing the overall density. The guide ramp 123 guides the water flow downward and backward when the bow enters the water, reducing the water flow impact resistance at the front of the hull 100, while also reducing the bow sinking depth, making the attitude of the hull 100 more horizontal.

[0067] This solution directly increases the drainage volume through the water pressure plate 122 structure and optimizes the hydrodynamic performance by combining it with the guide slope 123. It can achieve the dual effect of increasing buoyancy and reducing resistance without relying on foam materials, effectively solving the risk of sinking caused by insufficient buoyancy of the hull 100. At the same time, by optimizing the water flow path, it reduces navigation resistance, making the go-kart 1000 more stable and maneuverable in complex waters.

[0068] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
