Abstract
Description
Technical Field
[0001] This utility model relates to the field of extreme marine sports, and more particularly to a wave plate with a hydrofoil reinforcement structure. Background Technology
[0002] With the rapid development of extreme water sports, such as kitesurfing and hydrofoil surfing, the market demand for lightweight, high-strength surfboards is increasing.
[0003] However, traditional hydrofoil channels are mainly made of plastic nylon with fibers, which are injection molded. Although they have a certain degree of rigidity and durability, they still need to be improved in practical applications. During high-intensity waveboard movements, such as jumping and flipping, the hydrofoil channels may crack or fall off due to external impact, affecting the overall structure of the hydrofoil channels and the waveboard itself. In addition, hydrofoil channels made of plastic nylon have a high density, and in order to maintain strength, they are made larger, which increases the overall weight of the waveboard and reduces the maneuverability. Therefore, improvements are necessary. Utility Model Content
[0004] Therefore, the primary objective of this invention is to provide a strong hydrofoil reinforcement structure; the secondary objective of this invention is to provide a lightweight hydrofoil reinforcement structure.
[0005] To achieve the above objectives, this utility model employs the following technical means:
[0006] This utility model provides a hydrofoil reinforcement structure, comprising: a plate body with two grooves at the bottom; and two hydrofoil grooves, wherein the two hydrofoil grooves are shaped as narrow, rounded rectangles and are respectively fixed in the two grooves of the plate body, and each of the two hydrofoil grooves is provided with a sliding T-groove and two placement grooves, and the two placement grooves are located adjacent to the sliding T-groove, and a joint of the two hydrofoil grooves is provided with several air holes.
[0007] The above also includes a hydrofoil assembly, wherein the hydrofoil assembly includes a base, four screw sets and a hydrofoil, wherein the base is connected to the two hydrofoil slots by the four screw sets and the hydrofoil is connected to the base.
[0008] The aforementioned screw assembly further includes a fixing screw and a nut. The fixing screw passes through four through holes provided in the base, and the nut is locked to the fixing screw from another direction. The nut slides from the placement groove of the two hydrofoil channels into the sliding T-groove, so that the base is connected to the two hydrofoil channels.
[0009] The bottom of the sliding T-groove of the aforementioned two hydrofoil grooves has a first width, the opening of the sliding T-groove has a second width, the placement groove has a third width, and the nut of the screw assembly has a fourth width. The first width is greater than the second width, the third width is greater than the fourth width, and the first width is equal to the third width.
[0010] The aforementioned two water jet grooves are glued and fixed to the two grooves of the plate.
[0011] The material of the aforementioned two hydrofoil channels is carbon fiber.
[0012] By employing the aforementioned technical means, this utility model can achieve the following effects:
[0013] 1. This utility model provides several air holes in the two water jet channels. These air holes increase the contact area with air when the two water jet channels are bonded to the plate. At the same time, when air bubbles are generated during the curing of the adhesive, they can be discharged through the air holes, reducing gaps and making the bond more compact, thereby improving the strength between the plate and the two water jet channels.
[0014] 2. By using carbon fiber as the material for the two hydrofoil channels, the weight of the same volume can be reduced by about 30% compared to plastic nylon plus fiber materials, thus reducing the overall weight of the plate. At the same time, carbon fiber has good physical properties, impact resistance, high strength and light weight, thereby achieving the purpose of lightweighting provided by this utility model.

Detailed Implementation
[0020] This utility model provides a hydrofoil reinforcement structure, comprising: a plate 1, two hydrofoil grooves 2 and a hydrofoil assembly 3; the above components are described below with reference to the accompanying drawings.
[0021] Please see Figure 1 and Figure 2 As shown, the plate 1 has two grooves 11 at its bottom, and the plate 1 is formed by curing carbon fiber or glass fiber with resin.
[0022] Please refer to the following: Figure 1 and Figure 2 As shown, the two water jet channels 2 are shaped as narrow, rounded rectangles and are glued and fixed to the two grooves 11 of the plate body 1. The two water jet channels 2 are respectively provided with a sliding T-groove 21 and two placement grooves 22. The two placement grooves 22 are located adjacent to the sliding T-groove 21. A joint 23 of the two water jet channels 2 is provided with several air holes 24.
[0023] Please see Figure 1 and Figure 2 As shown, the aforementioned hydrofoil assembly 3 includes a base 31, four screw sets 32, and a hydrofoil 33. The base 31 is connected to the sliding T-groove 21 of the two hydrofoil channels 2 by the four screw sets 32, and the hydrofoil 33 is connected to the base 31 for fixation. The screw sets 32 further include a fixing screw 321 and a nut 322. The fixing screw 321 extends through four through holes 311 provided in the base 31, and the nut 322 is locked to the fixing screw 321 from another direction. The nut 322 is inserted from the placement groove 22 of the two hydrofoil channels 2 and is engaged between the bottom 211 and the opening 212 of the sliding T-groove 21, so that the base 31 is connected to the two hydrofoil channels 2 without shaking.
[0024] Therefore, please refer to Figures 2 to 4 As shown, this utility model provides a preferred embodiment of a hydrofoil reinforcement structure. The plate 1 of a hydrofoil reinforcement structure A has two grooves 11 pre-reserved. After the processor applies adhesive to the joint 23 of the two hydrofoil grooves 2, it is placed in the two grooves 11 and pressed to fix it. Excess adhesive residue and air bubbles generated during the drying process flow out from the several air holes 24, increasing the tightness between the plate 1 and the two hydrofoil grooves 2, thereby increasing the strength between them.
[0025] Please see Figures 2 to 4As shown, the two hydrofoil channels 2 are made of carbon fiber. After pre-impregnation of carbon fiber, they are hot-pressed into shape, which reduces the weight by 30% and increases the tensile strength by 2 to 3 times. In addition to being lightweight, it also improves the longitudinal and transverse strength. The two placement slots 22 of the two hydrofoil channels 2 are then machined, and the base 31 and the four screw groups 32 are connected to the two hydrofoil channels 2. Finally, the hydrofoil 33 is connected to the base 31, thereby achieving the purpose of this utility model to provide a strong and lightweight wave plate.
[0026] Please see Figure 4 As shown, it is worth mentioning that the bottom 211 of the sliding T-groove 21 of the two hydrofoil channels 2 has a first width W1, the opening 212 of the sliding T-groove 21 has a second width W2, the placement groove 22 has a third width W3, and the nut 322 of the screw assembly 32 has a fourth width W4. The first width W1 is greater than the second width W2, the third width W3 is greater than the fourth width W4, and the first width W1 is equal to the third width W3. That is, the nut 322 can be inserted into the bottom 211 of the groove through the placement groove 22, and the opening 212 holds the nut 322, so that the nut 322 can slide and adjust its position in the sliding T-groove 21, without the screw assembly 32 and the base 31 sliding directly from the sliding T-groove 21 of the two hydrofoil channels 2.
[0027] It should be noted that the above description is the technical principle used in the specific embodiments of this utility model. If any changes are made in accordance with the concept of this utility model, and the resulting functions and effects do not exceed the spirit covered by the specification and drawings of this utility model, they should be included within the protection scope of this utility model.
