Example 1

The embodiment provides an electric surfboard, as the surfing equipment on water, can provide drive power for surfing on water for the user can freely slide on the surface of water, does not receive the restriction that the stormy waves have or not, also need not to realize sliding with the help of external pulling.

Referring to fig. 1 to 3, the electric surfboard includes a surfboard body 100, an embedded battery compartment 200, an embedded connection assembly 300, and an embedded reinforcement assembly 400. The pre-buried reinforcing component 400 is at least partially clamped between the pre-buried battery compartment 200 and the pre-buried connecting component 300, and the modulus of the pre-buried reinforcing component is smaller than the moduli of the pre-buried battery compartment 200 and the pre-buried connecting component 300 and is larger than the supporting modulus of the surfboard body 100. The surfboard body 100 is formed by foaming and covers the embedded battery compartment 200, the embedded connection assembly 300 and the embedded reinforcement assembly 400, and the embedded battery compartment 200 and the embedded connection assembly 300 are respectively exposed from the upper surface and the lower surface of the surfboard body 100.

As described above, the embedded battery compartment 200 is embedded in the surfboard body 100, and is used for installing/accommodating components such as a battery, a controller, and the like of the electric surfboard. The embedded connection assembly 300 is embedded in the surfboard body 100 and used for installing the connection rod 500, and the connection rod 500 is provided with the power hydrofoil 600 and the steering balance wing 700. The pre-buried battery compartment 200 and the pre-buried coupling assembling 300 are communicated with each other, and the connecting rod 500 is hollow and used for routing, so that the control signals of the battery and the controller are connected to the power hydrofoil 600 to drive the power hydrofoil 600 to rotate. When the power hydrofoil 600 rotates, the power hydrofoil and the steering balance wing 700 act together to provide thrust and lift for the surfboard body 100, so that the surfboard body 100 can be separated from the water surface for sliding.

The embedded battery compartment 200 and the embedded connection assembly 300 are respectively exposed from the upper surface and the lower surface of the surfboard body 100, and thus the embedded battery compartment 200 and the embedded connection assembly 300 are stacked in the thickness direction of the surfboard body 100. The stacking thickness of the pre-buried battery compartment 200 and the pre-buried connection assembly 300, that is, the thickness of the surfboard body 100, should ensure that the deformation is small when the force is applied, and therefore, the modulus of the pre-buried battery compartment 200 and the pre-buried connection assembly should be required.

Because pre-buried battery compartment 200 and pre-buried coupling assembling 300 deformation when the atress should guarantee to warp less, and the two is when the contact, and the degree of difficulty that forms the close laminating is great, and the roughness requirement to the two is great, and the possibility that has the clearance between the two is great. When the surfboard body 100 is formed by foaming, the gap between the two is filled with the filler of the surfboard body 100. Meanwhile, besides the contact surfaces, the embedded battery compartment 200 and the embedded connection assembly 300 have structures which are not in contact with each other but are arranged at intervals due to the respective structures of the embedded battery compartment and the embedded connection assembly, and filler of the surfboard body 100 is also filled between the structures arranged at intervals. However, because the modulus of the material of the surfboard body 100 is small, the surfboard body is easy to deform when stressed, so that the supporting effect on the embedded battery compartment 200 and the embedded connection assembly 300 is poor, and the embedded battery compartment 200 and the embedded connection assembly 300, especially the embedded battery compartment 200, are easy to deform when stressed.

Through clamping the pre-buried reinforcing component 400 between the pre-buried battery compartment 200 and the pre-buried connecting component 300, the modulus of the pre-buried reinforcing component 400 is smaller than the moduli of the pre-buried battery compartment 200 and the pre-buried connecting component 300, but is larger than the modulus of the surfboard body 100. Therefore, when the embedded reinforcing component 400 is clamped between the contact surfaces of the embedded battery bin 200 and the embedded connecting component 300, the gap between the embedded battery bin and the embedded connecting component on the contact surfaces can be eliminated, so that the force transmission between the embedded battery bin and the embedded connecting component is more uniform; when the embedded reinforcing assembly 400 is clamped between the spacing surfaces of the embedded battery compartment 200 and the embedded connecting assembly 300, the supporting strength of the material of the surfboard body 100 supported between the spacing surfaces can be enhanced.

Above-mentioned, pre-buried subassembly 400 is strengthened clamping and is located between pre-buried battery compartment 200 and pre-buried coupling assembling 300 the time can eliminate the contact gap between the two to and strengthen the support intensity between the structure that the interval between the two set up, make to form the contact that rigidity is big than surfboard body 100 between pre-buried battery compartment 200 and the pre-buried coupling assembling 300, guarantee that the atress transmits, the atress shares more evenly.

In this embodiment, the embedded battery compartment 200 and the embedded connection assembly 300 may be made of a carbon fiber material, and the carbon fiber has characteristics of light weight, high strength, high modulus, corrosion resistance, and the like. The surfboard body 100 is made of foam, specifically EPO (ex situ polymeric-emulsion) is a copolymer produced by a special polymerization process, and has unique composition and structure, and is composed of 30% of polyethylene and 70% of polystyrene. The PE component is mainly distributed on the outer layer of the particles to promote the plasticization and combination between the particles, and the PS component is mainly distributed inside the particles to have good supporting effect on the structure of the foam particles. EPO has the characteristics of high tearing resistance, high puncture resistance, high scratch resistance, high cracking resistance, high dimensional stability, high compressive strength and the like. The pre-buried reinforcing component 400 is foamed by PU (polyurethane), and has the characteristics of light weight and high strength.

Referring to fig. 4 to 5, in the present embodiment, the embedded connection assembly 300 includes a connection seat 310 and an embedded reinforcement seat 320, and the embedded reinforcement assembly 400 includes a first reinforcement member 410 and a second reinforcement member 420. The pre-buried reinforcing seat 320 includes a reinforcing plate 322 and a mounting neck 321 which are connected to each other, the connecting seat 310 is inserted into the mounting neck 321, and the reinforcing plate 322 is exposed from the lower surface of the surfboard body 100. A first reinforcing member 410 is arranged between the end face of the mounting neck 321 and the battery compartment, a plurality of second reinforcing members 420 are arranged on the reinforcing disc 322, and at least part of the second reinforcing members 420 are clamped between the reinforcing disc 322 and the embedded battery compartment 200.

Since the cross-sectional area of the connecting rod 500 of the electric surfboard is small, the cross-sectional area of the connecting seat 310 for installing the connecting rod 500 is also much smaller than that of the bottom surface of the pre-buried battery compartment 200. Through setting up pre-buried seat 320 of strengthening, increased the area of being connected of connecting seat 310 and surfboard body 100 on the one hand, the reinforcing disc 322 of the pre-buried seat 320 of strengthening of on the other hand provides effectual support for the battery compartment through second reinforcement 420 for the modulus of the pile body of pre-buried battery compartment 200, pre-buried coupling assembling 300, pre-buried reinforcing assembling 400 and surfboard body 100 is bigger, and the size is more stable during the atress.

The connecting rod 500 is connected to the connecting seat 310 and inserted into the mounting neck 321, and a tight contact, which may be an interference fit, is formed between the two on the insertion surface. The end face of the connecting base 310 is connected with a first reinforcing member 410, the first reinforcing member 410 is clamped between the mounting neck 321 and the embedded battery compartment 200, on one hand, the first reinforcing member 410 limits the separation between the connecting base 310 and the mounting neck 321, and on the other hand, the first reinforcing member 410 eliminates the gap between the mounting neck 321 and the embedded battery compartment 200. The joint surface of the pre-buried battery compartment 200 and the first reinforcement member 410 is provided with a wire slot, the first reinforcement member 410 and the connecting seat 310 are correspondingly provided with wire slots for routing, and an electric signal of a power source and a controller of the battery passes through the wire slot and the hollow connecting rod 500 to be connected to the power hydrofoil 600.

Be equipped with a plurality of second stiffeners 420 on pre-buried reinforcing disc 322 of strengthening the seat 320, second stiffener 420 encircles along the profile of reinforcing disc 322 and establishes, and the middle part of reinforcing disc 322 is located to installation neck 321, and installation neck 321 is located to second stiffener 420 ring to make reinforcing disc 322 atress more even.

The reinforcing plate 322 is formed with a back-off for limiting the embedded reinforcing seat 320 from being separated from the lower surface of the surfboard body 100. Further, the outer side of the reinforcing plate 322 is a slope, which makes the surface of the reinforcing plate 322 of the surfboard body 100 expand inward and outward. Certainly, the reinforcing disc 322 may also have other types of inverse fastening structures, for example, the outer side surface of the reinforcing disc 322 is a waist-shaped surface, that is, the two ends are large, the middle is small, the inverse fastening of the structure can effectively limit the up-and-down movement of the reinforcing disc 322, the outer side surface of the reinforcing disc 322 may also adopt a step surface, an arc surface, a special-shaped surface and the like besides an inclined surface, and the principle of the inverse fastening structure is that the reinforcing disc 322 can be limited from moving towards the lower surface of the surfboard body 100 by coating the foam of the surfboard body 100.

The pre-buried subassembly 400 of strengthening is pre-connected on pre-buried base 320 of strengthening when the installation, and first reinforcement 410 is connected on the terminal surface of connecting seat 310 and with the terminal surface butt of installation neck 321, connects connecting seat 310 on pre-buried base 320 of strengthening from this, and second reinforcement 420 is connected on reinforcing disc 322 to with pre-buried battery compartment 200 butt. The second reinforcement member 420 may be attached to the reinforcement disc 322 by adhesive means.

The second reinforcing member 420 is formed with an undercut for restricting the second reinforcing member 420 from being separated from the lower surface of the surfboard body 100. Further, the second reinforcement member 420 is a stepped shaft, one end of the large shaft diameter abuts against the bottom of the embedded battery compartment 200, and one end of the small shaft diameter is connected to the reinforcement disc 322.

In this embodiment, the reinforcing plate 322 and the pre-buried battery compartment 200 are staggered and opposite, a part of the second reinforcing member 420 on the reinforcing plate 322 is abutted to the bottom of the pre-buried battery compartment 200, and the other part of the second reinforcing member 420 is connected to the reinforcing plate 322 and embedded in the surfboard body 100, so that the connection strength between the reinforcing plate 322 and the surfboard body 100 is improved through the inverted buckle structure on the second reinforcing member 420, and the stable and firm connection between the reinforcing plate 322 and the surfboard body 100 is ensured.

The pre-buried battery compartment 200 includes a compartment body 210 and a supporting frame 220 formed at an outer edge of an opening of the compartment body 210, the pre-buried reinforcing assembly 400 is at least partially clamped between the compartment body 210 and the pre-buried connecting assembly 300, and the supporting frame 220 is exposed from an upper surface of the surfboard body 100. The bin body 210 is a container, a cavity for accommodating a battery, a controller and other components is formed on the bin body 210, meanwhile, the supporting frame 220 on the end surface of the bin body 210 is equivalent to the shoulder of the bin body 210, the supporting frame 220 is used for increasing the contact area between the bin body 210 and the surfboard body, and the bin body 210 can be effectively prevented from sinking relative to the surfboard body 100.

The support frame 220 is formed with an undercut for restricting the battery compartment from being separated from the upper surface of the surfboard body 100. It is understood that the inverted structure of the supporting frame 220 may be the same or similar to the inverted structure of the reinforcing plate 322, and will not be described herein. The supporting frame 220 is provided with a cover plate for covering the cartridge body 210, and the cover plate simultaneously provides support for a user on the electric surfboard, forming a part of the upper surface of the surfboard body 100.

The electric surfboard further includes a middle auxiliary fitting 110 and/or an auxiliary reinforcement 120 which are pre-embedded in the surfboard body 100. The auxiliary mounting member 110 and the auxiliary reinforcing member 120 may be arranged according to actual requirements, and are optional.

If it is necessary to reinforce a structure of a certain portion of the surfboard body 100, the auxiliary reinforcement member 120 may be embedded therein, and the material of the auxiliary reinforcement member 120 may be the same as that of the embedded reinforcement assembly 400, i.e., the first reinforcement member 410 and the second reinforcement member 420, or another high hardness foam harder than the foam material of the surfboard body 100 may be used. In this embodiment, since the head end of the surfboard body 100 has a weak structure, the auxiliary reinforcement member 120 is embedded in the head end, and the auxiliary reinforcement member 120 reinforces the strength of the head of the surfboard body 100, so that the surfboard body 100 has a good impact/collision resistance effect.

Further, a camera mounting seat 121 is embedded in the auxiliary reinforcing member 120, and the camera mounting seat 121 is exposed from the upper surface of the surfboard body 100 for mounting a camera, which may be Gopro, to record the surfing process.

It can be understood that the auxiliary reinforcing member 120 serves as a reinforcing structure and also serves as a mounting structure, so that the camera mounting base 121 has a relatively firm connection structure thereon. In other embodiments, the auxiliary reinforcement member 120 may be embedded in other positions of the surfboard body 100, for example, when the surfboard body 100 is not embedded in the embedded battery compartment 200 and the embedded connection assembly 300 is embedded in a position, that is, the whole surfboard body 100 is foamed in the thickness direction, the auxiliary reinforcement member 120 may be added to enhance the structural strength of the position.

Since the strength of the foam of the surfboard body 100 is low, and the connection effect is poor when other components are connected thereto, the auxiliary mounting member 110 may be embedded into the surfboard body to reinforce the strength of the connection structure of the surfboard body 100 at that location. If handles 111 are provided at both sides of the surfboard body 100, the handles 111 are installed by inserting the auxiliary installation members 110 at both sides of the surfboard body 100, and the handles 111 can be coupled to the auxiliary installation members 110 by screws. Similarly, the auxiliary mounting member 110 may be made of the same material as the pre-embedded reinforcement assembly 400, i.e., the first reinforcement member 410 and the second reinforcement member 420, or may be made of other high hardness foam harder than the foam material of the surfboard body 100. The auxiliary installation member 110 may be embedded directly in the surfboard body 100 during the forming of the surfboard body 100, or may be formed into a mounting groove for installing the auxiliary installation member 110 during the forming of the surfboard body 100, the auxiliary installation member 110 is installed in the mounting groove by bonding, and then the auxiliary installation member 110 is fixed by a surface skin 800 (mentioned below) of the surfboard body 100, and finally the screw on the handle 111 is connected to the auxiliary installation member 110 by the skin 800.

Referring to fig. 6 and 7, the electric surfboard further includes a skin 800 covering the surfboard body 100, and the strength of the skin 800 is higher than that of the surfboard body 100, so as to protect the surfboard body 100 (foam core board). The pre-buried battery compartment 200 and the pre-buried connection assembly 300 are exposed from the upper surface and the lower surface of the skin 800, respectively.

The skin 800 may be made of the same material as the pre-buried battery compartment 200 and the pre-buried connection assembly 300, for example, carbon fiber materials are used, so that the skin 800 is made of the same material as the exposed pre-buried battery compartment 200 and the pre-buried connection assembly 300. The pre-buried battery compartment 200 and the pre-buried coupling assembling 300 are respectively protruded from the upper surface and the lower surface of the surfboard body 100, after the skin 800 is wrapped, the pre-buried battery compartment 200 is level with the upper surface of the skin 800, and the pre-buried coupling assembling 300 is level with the lower surface of the skin 800, so that the joint of the skin 800 with the pre-buried battery compartment 200 and the pre-buried coupling assembling 300 can be in seamless butt joint, and the smoothness of the surface of the skin 800 is higher.

Further, a groove may be provided at the joint of the surfboard body 100 and the pre-buried battery compartment 200 and the pre-buried connection assembly 300, so that the joint area between the skin 800 and the side elevation surfaces of the pre-buried battery compartment 200 and the pre-buried connection assembly 300 is larger, and the joint between the skin 800 and the pre-buried battery compartment 200 and the pre-buried connection assembly 300 is firmer.

The skin 800 is formed of fibers laid on the surface of the surfboard body 100 and a cured binder wrapping the fibers. The fibers can be woven into a grid shape and laid on the surface of the surfboard body 100, then the surface of the surfboard body 100 is coated with the curing adhesive to coat and infiltrate the fibers, and the skin 800 on the surface of the surfboard body 100 is formed after curing, so that the surface strength of the surfboard body 100 is enhanced.

Skin 800 includes an upper surface skin, a lower surface skin, and a ring side skin, the strength of which is greater than the strength of the upper and lower surface skins. The main stress of the upper and lower surfaces of the surfboard body 100 is the supporting force, which comes from the human body and the connecting rod 500/water surface, and the loop side of the surfboard body 100 inevitably scrapes and collides with other objects, so the strength of the loop side skin should be set relatively high.

In this embodiment, the carbon fibers are laid on the upper surface and the lower surface of the surfboard body 100, and may be the carbon fiber woven mesh 810, and the ring side surface skin of the surfboard body 100 is provided with the kevlar fibers, and may be the kevlar fiber woven mesh 820. Then, epoxy resin is coated outside the surfboard body 100, so that the surfboard body 100 is completely coated. Because the strength of the Kevlar fiber is higher than that of the carbon fiber, the skin 800 with the ring side strength higher than that of the upper surface and the lower surface can be formed, so that the surfboard body 100 has better anti-collision and impact-resistant properties. The boundaries between the carbon fibers laid on the upper surface and the lower surface and the Kevlar fibers laid on the ring side surfaces may be in close contact or may be partially overlapped, thereby ensuring that the skin 800 has overall protective strength.

In other embodiments, the carbon fibers are laid on the upper surface, the lower surface and the ring side surface of the surfboard body 100, but the density of the skin 800 laid on the ring side surface of the surfboard body 100 is greater than the density of the skin 800 laid on the upper surface and the lower surface, so that the density of the carbon fibers in the ring side skin is greater than the density of the carbon fibers in the skin on the upper surface and the density of the carbon fibers in the skin on the lower surface, the thicknesses of the carbon fibers in the ring side skin may be the same, the sizes of the meshes of the carbon fiber woven meshes are different, and the sizes of the meshes of the carbon fiber woven meshes may be the same. In this way, the loop side of the surfboard body 100 can be ensured to have higher strength as well.

It should be noted that, communication components, such as an antenna, a network card, a bluetooth module, and the like, may be disposed on the surface of the surfboard body 100, and in order to avoid the skin 800 shielding signals, the skin 800 is not disposed on the surface of the surfboard body 100 on which the communication components are disposed.
