Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The present invention provides an electric surfboard 10, as shown in fig. 1 and 2, comprising: the body 100, the skegs 200, the flat bars 300, the motor assembly 400, and the underwater assembly 500. The flat bar 300 is fixedly installed on the body 100, and the motor assembly 400 and the underwater assembly 500 are installed on the flat bar 300.

Wherein, a battery (not shown) is disposed on the board body 100, the battery is electrically connected with the motor assembly 400 through a wire 101 (as shown in fig. 5), and a waterproof sealing structure 600 is disposed at the connection between the motor assembly 400 and the wire 101. As shown in fig. 3, the board body 100 is provided with a clamping seat 110, and the clamping seat 110 and the flat bar 300 are located on the same side of the board body 100, and the tail fin 200 is detachably disposed in the clamping seat 110.

When in use, the tail fin 200 and the flat bar 300 face the water surface, and the plate body 100 slides on the water surface in the initial driving process, and the tail fin 200 plays an important role in stability, response speed, direction changing capability and the like. After traveling at a certain speed, the underwater assembly 500 receives a certain pressure difference, and thus the panel body 100 is lifted up. For example, in the present embodiment, as shown in fig. 2, the underwater assembly 500 includes: the ejector rod 510, the front wing 520 and the tail wing 530 are respectively arranged at two ends of the ejector rod, wherein the ejector rod 510 is connected with the flat rod 300, and the front wing 520 and the tail wing 530 are respectively arranged at two ends of the ejector rod. When a certain speed is reached, the water pressure below the front wing 520 and the tail wing 530 is greater than the water pressure above it due to the bernoulli principle, thereby providing an upward lifting force to the electric surfboard 10.

The invention realizes convenient replacement of the tail fin 200 by matching the tail fin 200 with the clamping seat 110, and the specific description is as follows:

in this embodiment, as shown in fig. 4, the tail fin 200 is provided with a clamping portion 210 that is matched with the clamping seat 110, one side of the clamping seat 110 is provided with an opening 111, and the clamping portion 210 of the tail fin 200 slides in or slides out from the opening 111 of the clamping seat 110. The plate body 100 is provided with a lock block 120, and the lock block 120 is telescopically provided on the plate body 100 by a return spring 121. The locking block 120 is located at the opening 111 of the clamping seat 210, and a guiding inclined plane 122 is disposed on the locking block 120.

Preferably, as shown in fig. 4, a rack 211 is disposed on the clamping portion 210 of the tail fin 200, a gear 112 is disposed in the clamping seat 110, the rack 211 is meshed with the gear 112, and a force-accumulating torsion spring (not shown) is disposed between the gear 112 and the clamping seat 110.

When installing the tail fin 200, the user pushes the tail fin 200 by abutting the clamping portion 210 of the tail fin 200 against the guide slope 122 of the lock block 120; because of the guiding slope 122, the pushing of the tail fin 200 can cause the locking block 120 to be pressed and sunk, so that the opening 111 of the clamping seat 110 is exposed, and the clamping portion 210 of the tail fin 200 can slide into the clamping seat 110 from the opening 111. After the tail fin 200 completely enters the clamping seat 110, the locking block 120 is not stressed any more, and rises again under the action of the return spring 121 to block the opening 111, so that the tail fin 200 cannot slide out of the clamping seat 110;

it is noted that, in the process of the tail fin 200 entering the card socket 110, the rack 211 of the card connection portion 210 is engaged with the gear 112, and the rack 211 drives the gear 112 to rotate along with the sliding of the tail fin 200. During this period, the rotation of the gear 112 causes the elastic potential energy to be accumulated in the force-accumulating torsion spring, but since the tail fin 200 cannot slide out of the clamping seat 110, the elastic potential energy of the force-accumulating torsion spring cannot be released;

when the skeg 200 is removed, the user presses the locking block 120 so that it no longer blocks the opening 111 of the cartridge 110. At this time, the tail fin 200 has a condition of sliding out from the clamping seat 110, the force accumulating torsion spring reversely rotates the driving gear 112, and then drives the tail fin 200 to slide out of the clamping seat 110 through the engagement of the gear 112 and the rack 211, so that the tail fin 200 is disassembled.

Therefore, in the process of installing and detaching the tail fin 200, the user can change the matching state of the tail fin 200 and the clamping seat 110 only by simple operation, so that quick and convenient disassembly and replacement are realized.

Preferably, as shown in fig. 2 and 3, the number of the clamping seats 110 is two, the two clamping seats 110 are mirror-image arranged with the plane of the flat bar 300 as the symmetry plane, and the number of the tail fins 200 is the same as the number of the clamping seats 110. The symmetrical skegs 200 may allow the electric surfboard 10 to more smoothly travel during forward travel and better maintain straight travel.

In the practical use process, it is found that the connection part between the motor assembly 400 and the wire 101 is easy to be permeated with water vapor, and in order to realize safe use of the electric surfboard 10, the present invention particularly designs the waterproof sealing structure 600, which is specifically as follows:

the motor assembly 400 of the present invention includes a motor (not shown) and a housing 410, the wire 101 is inserted through the housing 410 and connected to the motor (as shown in fig. 5), and the waterproof sealing structure 600 is disposed at a position where the wire 101 is inserted through the housing 410. In the present invention, various embodiments are designed for the waterproof sealing structure 600.

Embodiment one:

as shown in fig. 6 and 7, the waterproof sealing structure 600 includes a rubber base 610 and an insert 620, the rubber base 610 is disposed on the hood 410, the wire 101 is threaded through the rubber base 610, and the insert 620 is detachably inserted into the rubber base 610. The insert 620 and the inner wall of the glue seat 610 together form a glue containing cavity 611, and sealant (not shown) is disposed in the glue containing cavity 611. The insert 620 is provided with an avoidance notch 621, and the wire 101 is positioned at the avoidance notch 621 and is abutted against the insert 620. The inner wall of the rubber seat 610 is provided with a limit groove 612, and the side wall of the plug 620 is clamped in the limit groove 612.

In use, the wire 101 passes through the glue seat 610 and a worker inserts the insert 620 onto the glue seat 610 and traps the wire 101 into the relief notch 621 of the insert 620. After plugging, the plug 620 is clamped with the limiting groove 612, and the plug 620 is in pressing contact with the wire 101. That is, the plugged insert 620 seals the gap between the glue seat 610 and the wire 101, so as to form a glue accommodating cavity 611 on the glue seat 610. Then, sealant is injected into the sealant accommodating cavity 611 and cured for a period of time, so that the position where the wire 101 passes through the hood 410 (the connection position between the motor assembly 400 and the wire 101) can be well watertight, and water vapor is prevented from entering.

Preferably, as shown in fig. 7, the insert 620 is provided with a bump 620a, and the bump 620a has two functions, namely, the arrangement of the bump 620a is beneficial to the staff to grasp, and the protruding bump 620a can be convenient to grasp and plug in due to the thinner insert 620, so as to avoid slipping during grasping; secondly, when the worker grabs the insert 620, the worker can identify the direction through the bump 620a, so that reverse plugging of the insert 620 is avoided.

Embodiment two:

as shown in fig. 8 and 9, the waterproof sealing structure 600 includes: the rubber seat 610, the first plug 630 and the second plug 640, the rubber seat 610 is arranged on the hood 410, the wire 101 penetrates through the rubber seat 610, and the first plug 630 and the second plug 640 are detachably inserted into the rubber seat 610. The first insert 630 and the second insert 640 cooperate with the glue seat 610 to form a first chamber 613 and a second chamber 614 together, and sealant (not shown) is disposed in each of the first chamber 613 and the second chamber 614.

Similar to the first embodiment, the first insert 630 is provided with a avoidance gap 621, and the wire 101 is located at the avoidance gap 621 and abuts against the first insert 630. The structure of the second card 640 is the same as that of the first card 630. The inner wall of the rubber base 610 is provided with a limiting groove 612, and the first insert 630 and the second insert 640 are both clamped in the limiting groove 612.

That is, the main difference of the present embodiment is that the number of the cards 620 is increased to two, the first card 630 and the second card 640, respectively, compared to the first embodiment. In use, the first insert 630 and the second insert 640 are sequentially inserted into the glue seat 610, and the two insert parts respectively block the gap between the wire 101 and the glue seat 610, so as to form a first chamber 613 and a second chamber 614; and then injecting sealant into the two chambers, and drying and solidifying the sealant.

It is emphasized that the directions of the escape notches 621 of the first insert 630 and the second insert 640 are different, and thus, when the wire 101 passes through the two escape notches 621, the wire 101 may be bent. In the first embodiment, since the wire 101 is clamped and fixed only by means of the single insert 620, during the solidification of the sealant, the shake of the wire 101 easily causes a gap between the insert 620 and the wire 101, thereby causing leakage of the sealant, resulting in poor sealing effect after solidification. In the second embodiment, since the wire 101 is bent (as shown in fig. 9), the first insert 630 and the second insert 640 are not easily pulled by the shaking of the wire 101, i.e. the contact stability between the wire 101 and the first insert 630 and between the wire 101 and the second insert 640 is better, and gaps are not easily generated, so that the expected sealing effect can be achieved after the sealant is solidified.

Embodiment III:

as shown in fig. 10 and 11, the waterproof sealing structure 600 includes a rubber base 610 and a mixing insert 650, the rubber base 610 is disposed on the hood 410, the wire 101 is threaded through the rubber base 610, and the mixing insert 650 is detachably inserted into the rubber base 610. The mixing insert 650 cooperates with the gum base 610 to form a first chamber 613 and a second chamber 614 (see embodiment two).

As shown in fig. 10, the mixing insert 650 includes a first plate surface 651 and a second plate surface 652, the first plate surface 651 is provided with a guide notch 651a, and an inner wall of the guide notch 651a is an inclined surface; the second plate 652 has an avoidance notch 621 formed therein, and the guide notch 651a is not oriented on the same side as the avoidance notch 621. The inner wall of the rubber seat 610 is provided with a limit groove 612, and the first plate 651 and the second plate 652 are both clamped in the limit groove 612.

In contrast to the embodiment, this embodiment is equivalent to combining the first insert 630 and the second insert 640 to form the hybrid insert 650. In use, the wire 101 is threaded through the glue base 610 and a worker inserts the mixing insert 650 onto the glue base 610. At this time, the second plate 652 is preferentially contacted with the wire 101, and slightly clamps the wire 101; as the mixing insert 650 is inserted, the guide notch 651a of the first plate 651 also contacts the wire 101 and pushes the wire 101 to one side. Thus, after the hybrid plug 650 is plugged, as shown in fig. 12, the shape of the wire 101 is bent (similar to the embodiment). After plugging, a first chamber 613 and a second chamber 614 are formed on the glue base 610, and then sealant is injected into the first chamber and the second chamber, and the glue base is ready for airing and solidification.

Compared to the second embodiment, the hybrid plug 650 can achieve the effect of bending the wire 101 (the benefit of the bending effect is as described above), and the hybrid plug 650 only needs to perform the plugging operation once, while the first plug 630 and the second plug 640 of the second embodiment need to perform the plugging operation twice, which can simplify the operation and thus improve the working efficiency.

Further, in the third embodiment, the mixing insert 650 has the guide notch 651a, and the inner wall of the guide notch 651a is an inclined surface, which has the following advantages: on the one hand, the guide notch 651a can push the wire 101 to one side in the plugging process, so that the effect of bending the wire is achieved; on the other hand, after the plugging is completed, the guide notch 651a enables the first chamber 613 and the second chamber 614 to be mutually communicated, so that only one of the chambers needs to be injected during glue injection, and the glue can still fill the two chambers.

Preferably, as shown in fig. 10, a shielding plate 653 is provided on the first plate face 651, the shielding plate 653 is covered on the first chamber 613, and injection holes 653a are provided on the shielding plate 653. After plugging, the shielding plate 653 covers and plugs the first chamber 613; in injecting the glue, an injection needle (not shown) passes through the injection hole 653a and injects the glue into the first chamber 613. So designed, during glue injection, there will be a certain gas pressure in the upper half of the first chamber 613 (gas is difficult to exit the first chamber 613) so that viscous glue can be quickly forced into the second chamber 614. Further, the shield 653 can prevent glue from splashing out of the first chamber 613 during injection.

Thus far, three embodiments of the waterproof sealing structure 600 have been described, the waterproof sealing structure 600 can effectively seal the junction between the motor assembly 400 and the wire 101, thereby preventing the water vapor from affecting the motor assembly 400.

In summary, according to the electric surfboard 10 of the present invention, the tail fin 200 can be replaced conveniently and rapidly according to actual needs, so as to reduce the operation difficulty of users and improve the comfort of use.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
