Description

Technical Field

[0001] The utility model relates to a surfboard, in particular to a surfboard with a protective plate. Background Art

[0002] The existing electrically-driven surfboard is made by a processing method of forming a buoyant surfboard body with an internal skeleton and an outer foaming material. A water jet pump system for power and a tail fin for guiding are installed at the rear of the bottom surface of the surfboard body. The outer surface of the formed foam is exposed and lacks protection. During the processes of the surfboard gliding on water, being stored, carried and transported, the bottom surface of the formed foam may be damaged due to accidental collisions, such as scratches on the bottom surface, or even partial defects or hidden cracks. These damages will not only shorten the service life of the surfboard, but also pose potential safety hazards. The hidden cracks may cause the formed foam to break during the operation of the surfboard. Moreover, when the surfboard is skiing on water, it will increase the resistance in contact with the water surface, resulting in an increase in power consumption and a shorter endurance of the surfboard during operation, seriously affecting the surfing experience. The severely damaged surfboard needs to be returned to the factory for repair or even replacement, increasing the user's cost of use. Content of the Utility Model

[0003] In order to solve the technical problems that the bottom surface of the formed foam of the existing surfboard is exposed and lacks protection, and is damaged during the processes of storage, handling and transportation, resulting in scratches on the bottom surface, partial defects or even hidden cracks, thus shortening the service life of the surfboard, posing potential safety hazards, increasing power consumption during operation and deteriorating the surfing experience, the utility model provides a surfboard with a protective plate. The surfboard is provided with a protective plate attached to the bottom surface of the formed foam for protection, so as to avoid the damage of the formed foam during the processes of operation, storage, handling, etc. due to the exposed bottom surface, as well as the potential hazards of scratches, damage and cracks on the bottom surface of the surfboard caused by the damage, ensuring the preset service life and safety of the surfboard, improving the surfing experience, and also avoiding the return to the factory for repair and replacement caused by the damage of the bottom surface of the foam.

[0004] Technical solution adopted by the present utility model to solve the technical problem: A surfboard with a protective plate, comprising a surfboard body composed of a molded foam body. A spray pump system and a fin are installed at the rear of the surfboard body. A skeleton is provided inside the molded foam body, and a fin mounting position is provided at the rear of the bottom surface of the molded foam body. The feature is that a protective plate is adhesively provided on the bottom surface of the molded foam body, and the protective plate covers a part of the bottom surface of the molded foam body in front of the fin mounting position. By adhesively providing a protective plate under the surfboard body to cover a part of the bottom surface of the molded foam body in front of the fin mounting position for isolation protection, it prevents damage caused by the exposure of the bottom surface of this part of the molded foam body, which affects water skiing, as well as the resulting problems of returning to the factory for repair and replacement; since the protective plate is adhesively attached to the bottom surface and its shape matches the bottom surface, when the surfboard is skiing on water, the protective plate replaces the bottom surface of the molded foam body it covers and touches the water for skiing, without affecting the normal use of the surfboard. The protective plate can be made of a high-hardness material that is not easily damaged and is not easily damaged and remains intact during daily use, handling, storage, etc., ensuring the service life and use safety of the surfboard body. In addition, the outer surface of the protective plate can be made smoother than the bottom surface of the molded foam body, reducing the resistance during water skiing and helping to further extend the working endurance time of the surfboard.

[0005] As a further improvement and supplement to the above technical solution, the present utility model adopts the following technical measures: Further, the protective plate is wrapped inside the peripheral edge of the bottom surface of the molded foam body, and the protective plate is flush with the bottom surface of the adjacent molded foam body along its peripheral edge. When the surfboard is skiing on water, the working area in contact with the water is mainly through the part of the bottom surface inside the peripheral edge. By setting the protective plate to wrap the aforementioned inner peripheral edge, it can fully cover the bottom surface of the foam body within the working area, meet the use requirements of surfboard water skiing protection, and control the production cost by limiting the area of the protective plate; at the same time, the protective plate can be protected by the molded foam body on its outside and separated from the surrounding, avoiding the peripheral edge of the protective plate being exposed on the outermost surface of the surfboard and being collided to cause loosening or damage, affecting its protective effect and surfboard water skiing.

[0006] Further, the adhesive setting of the bottom surface of the molded foam body and the protective plate is a snap fit. The bottom surfaces of the protective plate and the molded foam body are respectively provided with mating docking edges and interfaces. Through the tight fit of the docking edge and the interface, the protective plate is tightly fitted and adhered to the bottom surface of the molded foam body. When the protective plate needs to be replaced, it can be pried open from the edge where it is adhered to the bottom surface of the molded foam body to remove the protective plate.

[0007] Further, the docking edge is provided on the peripheral edge of the protective plate, and the docking edge is continuously or discontinuously provided along the peripheral edge of the protective plate. The docking edge is located at the peripheral edge of the protective plate and can be continuously provided along the peripheral edge or several are discontinuously provided.

[0008] Furthermore, the docking edge is a vertical folding edge formed by bending the periphery of the protective plate upward, and a card slot matching the vertical folding edge is arranged on the bottom surface of the formed foam body. The vertical folding edge is formed by bending and extending the periphery of the protective plate as the docking edge for connecting and fixing with the formed foam body. At the same time, a card slot matching the vertical folding edge is arranged on the bottom surface of the formed foam body as the interface for connecting the protective plate. When the bottom surface of the protective plate is attached to the bottom surface of the formed foam body, the vertical folding edge is inserted into the corresponding card slot and tightly fitted with it, so that the bottom surface of the protective plate is attached to the bottom surface of the formed foam body.

[0009] Furthermore, an adhesive is applied to the inner surface and / or the outer surface of the vertical folding edge. By applying glue to one of the inner surface and the outer surface of the vertical folding edge, or applying glue to both the inner and outer surfaces, the installation of the protective plate can be further strengthened. Compared with the connection method of passing screws through the skeleton to fasten the protective plate, the cooperation of the vertical folding edge and the card slot plus glue reinforcement is simpler and more practical in structure and has higher efficiency.

[0010] Furthermore, the vertical folding edge is continuously arranged around the periphery of the protective plate and forms a closed enclosure protruding from the edge of the protective plate. The vertical folding edge continuously forms a protruding closed enclosure around the periphery of the protective plate. As the docking edge, it matches the card slot on the bottom surface of the formed foam body. The extension of the connection section of the two can further improve the firmness of the docking, and the strength of the vertical folding edge forming the closed enclosure is also higher than that when it is arranged dispersedly and intermittently.

[0011] Furthermore, the vertical height H and the transverse wall thickness L of the closed enclosure are each kept consistent in the extending length direction. The closed enclosure maintains a unified vertical height and transverse wall thickness along the length direction, without sudden changes, which is convenient for processing and manufacturing, and is also convenient for the grooving processing of the bottom surface of the formed foam body.

[0012] Furthermore, the vertical height H is 6 - 8 cm, and the transverse wall thickness L is 1.5 - 3 cm. The height and thickness of the vertical folding edge within this range can make the connection between the protective plate and the formed foam body stable, preventing inconvenient installation and increased costs caused by improper dimensions.

[0013] Further, two symmetric fin mounting positions are provided on the bottom surface of the formed foam body, which are arranged on both sides. An inner concave is formed on the bottom surface between the two fin mounting positions to form a power mounting position for accommodating the spray pump system. The rear end of the protective plate extends to form a bifurcated structure that matches the power mounting position. The bifurcated structure has two bifurcated parts arranged on the left and right sides of the power mounting position, and a U-shaped gap is formed between the two bifurcated parts; the protective plate extends in a gradually upwardly curved arc in both the front and rear directions starting from the common connection point at the ends of the two bifurcated parts. Two symmetric fin mounting positions are provided on the bottom surface of the formed foam body, enabling two symmetric fins on both sides of the rear part of the surfboard to guide water. The spray pump system is installed in the inner concave power mounting position left on the bottom surface of the foam body between the two fins. The rear end of the protective plate bifurcates to bypass the power mounting position, and the spray pump system can be placed into the power mounting position through the U-shaped gap formed by the bifurcation for installation. Starting from the common connection position where the ends of the two bifurcated parts are located, the protective plate extends while gradually curving upward in both the forward and backward directions to form corresponding arcs, adapting to the best water skiing effect when the surfboard is working.

[0014] The beneficial technical effects of the present utility model: A protective plate is attached to the side below the surfboard body to cover part of the bottom surface of the formed foam body for isolation protection, avoiding the exposure of the bottom surface of the formed foam body from being damaged, which affects water skiing, as well as the return to the factory for repair and replacement caused by the damage, prolonging the service life of the surfboard and enhancing the surfing experience.

[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0023] As shown Figures 1 - 6 in the figure, a surfboard with a protective plate includes a surfboard body composed of a molded foam 1. A spray pump system and a fin (not shown in the figure) are installed at the rear of the surfboard body. The molded foam in this embodiment can be made of polypropylene foam material (abbreviation: EPP), polyethylene foam material (abbreviation: EPE), polystyrene material (abbreviation: EPS), etc. Preferably, the molded foam is made of polypropylene foam material. A skeleton formed by splicing metal beam members is provided inside the molded foam 1. A fin mounting position 2 is provided at the rear of the bottom surface of the molded foam 1. A protective plate 3 is attached to the bottom surface of the molded foam 1. The protective plate 3 covers a part of the bottom surface of the molded foam 1 in front of the fin mounting position 2. Specifically, as shown Figure 2 in the figure, the protective plate 3 is wrapped around the inner side of the peripheral edge of the bottom surface of the molded foam 1. The protective plate 3 is flush with the bottom surface of the adjacent molded foam 1 along its peripheral edge. The connection between the bottom surface of the molded foam 1 and the protective plate 3 is clamped and fastened. Docking edges 4 and interfaces that can be tightly fitted are respectively provided on the bottom surfaces of the protective plate 3 and the molded foam 1.

[0024] The protective plate covers the part of the bottom surface of the molded foam in front of the fin mounting position along the lower surface of the surfboard body for isolation and protection, effectively protecting this part of the bottom surface of the molded foam and preventing it from being damaged due to exposure, which may affect water skiing and pose safety hazards, as well as the resulting problems of returning to the factory for repair and replacement. The protective plate fits the bottom surface and has a shape matching the bottom surface. When the surfboard is skiing on water, the protective plate replaces the covered bottom surface of the molded foam to touch the water and slide, without affecting the normal use of the surfboard. The protective plate can be made of a high-hardness material that is not easily damaged and is not easily damaged during daily use, handling, storage, etc., and can remain intact. Moreover, the outer surface of the protective plate can be made smoother than the bottom surface of the molded foam, reducing the resistance when skiing on water, and helping to further extend the working endurance time of the surfboard while protecting the surfboard body. During use, an anti-slip mat can also be pasted on the upper surface of the surfboard body, i.e., the molded foam.

[0025] Further, the docking edge 4 is provided at the periphery of the protection plate 3, and the docking edge 4 is arranged continuously or discontinuously along the periphery of the protection plate 3. In this embodiment, it is preferably that the docking edge 4 is continuous in a circle along the periphery of the protection plate 3. The docking edge 4 in this embodiment is a vertical folded edge formed by bending the periphery of the protection plate 3 upward. The vertical folded edge is continuously arranged in a circle along the periphery of the protection plate 3 and forms a closed enclosure protruding from the edge of the protection plate 3. The vertical height H and the transverse wall thickness L of the closed enclosure are each consistent in the extending length direction thereof. In this embodiment, the vertical height H is 6-8 cm, preferably 7.5 cm, and the transverse wall thickness L is 1.5-3 cm, preferably 2.5 cm; a card slot matching the vertical folded edge is provided on the bottom surface of the molded foam 1. In order to make the docking between the protection plate and the molded foam more firm, an adhesive is applied to the inner surface and / or the outer surface of the vertical folded edge. Preferably, the adhesive is applied to the inner surface of the vertical folded edge. After the adhesive is applied, the vertical folded edge of the protection plate is aligned with the card slot on the bottom surface of the molded foam, and by knocking on the protection plate, the vertical folded edge is inserted into the card slot for a tight fit. After the protection plate is snapped in place, as the glue cures, the protection plate and the molded foam are firmly adhered together.

[0026] As Figure 4 and Figure 6 shown, two symmetrically arranged fin mounting positions 2 are provided on the bottom surface of the molded foam 1 and are arranged on both sides. An inner concave portion is formed on the bottom surface between the two fin mounting positions 2 to form a power mounting position 5 for accommodating the spray pump system. The rear end of the protection plate 3 extends to form a bifurcated structure matching the power mounting position 5. The bifurcated structure has two bifurcated portions 3-1 arranged on the left and right sides of the power mounting position 5. A U-shaped gap 3-2 is formed between the two bifurcated portions 3-1. At the same time, the protection plate 3 starts from the common connection point at the ends of the two bifurcated portions 3-1 and makes a gradually upwardly curved extension in both the front and rear directions.

[0027] Two symmetrically arranged fins can be installed on both sides of the rear part of the surfboard to guide water. The spray pump system is installed in the inner concave power mounting position left on the bottom surface of the foam between the two fins. The rear end of the protection plate bifurcates to bypass the power mounting position to prevent interference. The spray pump system can be placed into the power mounting position through the U-shaped gap formed by the bifurcation for installation. At the same time, starting from the common connection position where the ends of the two bifurcated portions are located, the protection plate extends and gradually curves upward in both the forward and backward directions to form corresponding arcs, adapting to the best water skiing effect when the surfboard is working.
