Description

Technical Field

[0001] The invention relates to an electric surfboard, in particular to a remote control handle which can be used as a handrail and an electric surfboard using the remote control handle. Background Art

[0002] When using an electric surfboard, a remote control handle is held in one hand to control the water jet power device and adjust the surfboard's water-skiing speed. When riding an electric surfboard, a novice must hold the two handrails at the front of the surfboard with both hands to stabilize the surfboard during the start-up phase. One of their hands must also operate the remote control handle, which is very inconvenient for novices. Since the novice's hand holding the remote control must use fingers to hook the handrails, it is difficult to hold the handrails firmly, which also seriously affects the operation of the remote control handle. This makes it more difficult for novices to learn to ride a surfboard. If they cannot hold the handrails firmly, it is even more difficult to maintain balance and they are more likely to fall into the water. Once the surfboard is gliding steadily, the user can stand up and play. At this time, they only need to hold the remote control handle to operate, without having to hold the handrails. Summary of the Invention

[0003] In order to solve the technical problems that the handrails and remote control handles on existing electric surfboards are set separately, which makes it inconvenient for novice surfers to operate them during the starting stage, increases the difficulty for novice surfers to learn to use surfboards, and increases the risk of falling into the water, the present invention provides a remote control handle that can be used as an handrail and an electric surfboard using the same. The remote control handle can be used as an handrail by being clipped onto a mounting seat that fixes the surfboard body. When used as an armrest, it does not affect the operation of the remote control handle. It is greatly convenient for novice surfers to hold the handrail and operate the remote control handle at the same time during the starting stage, helping novice surfers to better maintain body balance and prevent falling into the water, and novice surfers can learn to use the electric surfboard more easily. The electric surfboard using the above remote control handle is friendly to novice surfers. Novices can hold the handrails to maintain balance while freely operating the remote control handle, learn to use the electric surfboard, and enjoy the fun of surfing.

[0004] The present invention solves the technical problem by adopting a technical solution: a remote control handle that can serve as a handrail, comprising a remote control handle having a grip portion and an operating switch, the operating switch and grip portion being adjacent along the length of the remote control handle. The remote control handle is detachably connected to a mounting base fixed to the front of an electric surfboard, and when the remote control handle is attached to the mounting base, a gap is formed between the remote control handle and the mounting base, allowing a hand to pass through the gap to grasp the grip portion and operate the operating switch. The present invention provides a detachable connection between the remote control handle and the mounting base fixed to the front of the electric surfboard, allowing the remote control handle to double as a handrail on the electric surfboard when attached to the mounting base without interfering with the operation of the remote control handle. This effectively solves the problem of existing electric surfboards having separate handrails and remote control handles, which is unfriendly to novice surfers and makes it difficult for novice surfers to simultaneously grasp the remote control handle and the handrail, making surfing difficult and potentially causing falls into the water. Using this remote control handle, novice surfers can grasp the remote control handle, which serves as a handrail, and operate the surfboard simultaneously during the take-off phase, making surfing more convenient, easy, and safer for beginners.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the grip portion and the operating switch are located between the front and rear ends of the remote control handle, the mounting base is elongated, and at least one end of the mounting base is detachably connected to the end of the remote control handle, and a detachable connection structure is provided between the detachably connected mounting base end and the corresponding end of the remote control handle. When the mounting base and the remote control handle are connected, the grip portion and the operating switch are both suspended above the mounting base and form a gap between the mounting base. The mounting base is elongated and can match the shape of the remote control handle. The mounting base is detachably connected to the remote control handle through the end, and one end of the mounting base can match the corresponding end of the remote control handle, or both ends of the mounting base can match both ends of the remote control handle. When the mounting base and the remote control handle are connected, the grip portion and the operating switch form a gap between the front and rear ends of the handle and the surface of the mounting base, so that the grip portion and the operating switch are both suspended above the mounting base, so that a finger can pass through the gap, grasp the grip portion, hold the remote control handle, and at the same time, use the operating switch to control the speed of the electric surfboard normally.

[0006] The front end of the remote control handle and the front end of the mounting base are respectively provided with matching positioning hooks and limit pins. Matching protrusions and recessed holes are provided between the rear end of the remote control handle and the rear end of the mounting base. When the remote control handle and the mounting base are connected, the positioning hook engages the limit pin and the protrusion inserts into the recessed hole. When the remote control handle and the mounting base are separated, the positioning hook disengages from the limit pin and the protrusion disengages from the recessed hole. The remote control handle and the mounting base are connected by matching or separating the front and rear ends to achieve a detachable connection. When the remote control handle and the mounting base are connected, the positioning hook engages the limit pin and the protrusion inserts into the recessed hole. When the remote control handle and the mounting base are separated, the positioning hook disengages from the limit pin and the protrusion disengages from the recessed hole.

[0007] The positioning hook bends and extends outward on a plane parallel to the extension direction of the remote control handle. The limit pin is fixedly connected to the mounting seat at its end and is suspended above the mounting seat, forming a gap between the limit pin and the mounting seat below. The remote control handle can be rotated to allow the positioning hook to partially penetrate the gap and hook the limit pin. The plane on which the positioning hook bends and extends is parallel to the extension direction of the remote control handle. The limit pin that matches the positioning hook is suspended above the mounting seat, forming a gap between the limit pin and the mounting seat for the positioning hook to penetrate. After the positioning hook partially penetrates the gap, it rotates with the remote control handle to hook the limit pin. During use, two raised portions protruding from the surface can be provided on the mounting seat, so that the two ends of the limit pin are fixed to the two raised portions, so that the limit pin is suspended above the mounting seat.

[0008] The positioning hook is composed of a vertical section and a horizontal section that intersect vertically. The vertical section is fixed to the front end of the remote control handle and extends outward. The inner surface of the vertical and horizontal sections at the connection forms a concave arc surface that can fit the limit pin. When the positioning hook hooks the limit pin, the concave arc surface is close to the side wall of the limit pin, and the horizontal section penetrates into the gap between the limit pin and the mounting seat. The positioning hook is composed of two vertical sections and horizontal sections that are connected vertically, and the two are provided with a concave arc surface at the connection. The outward-extending vertical section can keep the remote control handle away from the mounting seat, preventing the operating switch from being too close to the mounting seat and affecting its use. The horizontal section is perpendicular to the vertical section, and the connection between the two forms an arc surface that fits the limit pin to hook the limit pin. When the remote control handle is connected to the mounting base for use, gripping the remote control handle will cause opposite forces on the front and rear ends of the remote control handle. The force on the front end of the handle tends to pull upward, and at this time the arc surface is close to the limit pin. At the same time, the horizontal section passing between the limit pin and the mounting base causes the positioning hook to tightly hook the limit pin; the force on the rear end of the handle tends to press downward, making the convex part and the concave hole fit more tightly.

[0009] A limiting structure is provided between the convex portion and the concave hole to prevent the remote control handle and the mounting base from being loosened. The limiting structure prevents the remote control handle and the mounting base from being loosened and shaking after being connected, and further improves the stability of the connection between the remote control handle and the mounting base.

[0010] The limiting structure comprises matching protrusions and recesses. When the protrusion and recess are properly inserted, the protrusion snaps into the recess, and when the protrusion and recess are disengaged, the protrusion slips out of the recess. The matching protrusions and recesses create a snap connection between the outer surface of the protrusion and the inner wall of the recess, improving the stability of the connection between the rear end of the remote control handle and the rear end of the mounting base and preventing shaking. One of the protrusions and recesses is located on the side of the protrusion, while the other is located on the inner wall of the recess. The positions of the protrusions and recesses are also interchangeable. When an electric surfboard is moved, the vibrations of the surfboard can cause the remote control handle mounted on the mounting base to shake or even become loose. The matching protrusions and recesses are used to limit the connection between the remote control handle and the mounting base.

[0011] The protrusion and recess are located at the rear end of the remote control handle and the rear end of the mounting base, respectively. The protrusion and recess are located on the inner wall of the recess and the side of the protrusion, respectively, and extend perpendicularly to the direction in which the protrusion is inserted into the recess. The protrusion and recess are located on the inner wall of the recess and the side of the protrusion, respectively. When the protrusion is fully inserted into the recess, the protrusion snaps into the recess, and the extension direction of the protrusion and recess is perpendicular to the direction in which the protrusion is inserted into the recess.

[0012] The remote controller has a speed range switch located on the back of the operating switch. The speed range switch can be adjusted by sliding it linearly or rotating it back and forth to adjust the speed of the electric surfboard. The speed range switch further enhances the controllability of the remote controller. By operating the speed range switch, the electric surfboard's water jet power device can be adjusted to operate at high or low speeds, making it more user-friendly for beginners. Beginners can first practice at low speeds to master balance, and then switch to high speeds once they become proficient, increasing the thrill and fun of surfing. The speed range switch can be switched between different speed ranges by sliding it linearly or rotating it back and forth.

[0013] A second object of the present invention is to provide an electric surfboard comprising a surfboard body and a matching remote control handle. The surfboard body is provided with a water jetting device operable via the remote control handle. The front portion of the surfboard body is provided with two handrails, characterized in that one of the two handrails is a remote control handle connected to the surfboard body, and the remote control handle is detachably connected to the surfboard body using one of the aforementioned handrail-capable remote control handles. The electric surfboard utilizes the aforementioned handrail-capable remote control handle, allowing the remote control handle to be attached to the surfboard body and serve as a handrail without interfering with the operation of the remote control handle. This solves the inconvenience faced by novice surfers who have to simultaneously hold both the handrail and the remote control handle, resulting in difficulties in learning to surf, difficulty maintaining balance, and potential falls into the water. During the take-off phase of the surfboard, novice surfers can easily grasp the remote control handle as a handrail while operating it simultaneously, making surfing learning more convenient, easier, and safer. The remote control handle for operating the water jetting device is prior art and will not be further described.

[0014] The beneficial technical effects of the present invention are as follows: the remote control handle and the mounting base are detachably connected, so that the remote control handle can be installed on the surfboard body and used as a handrail without affecting the operation of the remote control handle, so that novice surfers can conveniently hold the handrail and operate the remote control handle at the same time during the start-up phase, thereby helping novices to better maintain body balance and prevent falling into the water, and novices can learn to use the electric surfboard more easily. After becoming proficient, the remote control handle can be separated from the surfboard body; the electric surfboard uses the aforementioned remote control handle, which is friendly to novices learning to surf. Novices can hold the handrail to maintain balance while freely operating the remote control handle, learn to use the electric surfboard, and enjoy the fun of surfing.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6As shown, embodiment 1 is a remote control handle that can serve as a handrail. It includes a remote control handle 1 having a grip portion 1-1 and an operating switch 1-2. The operating switch 1-2 and the grip portion 1-1 are adjacent to each other along the length of the remote control handle 1. The remote control handle 1 is detachably connected to a mounting base 2 fixed to the front of the electric surfboard. When the remote control handle 1 is connected to the mounting base 2, a gap is formed between the remote control handle 1 and the mounting base 2, allowing a hand to pass through the gap to grasp the grip portion 1-1 and operate the operating switch 1-2. The grip portion 1-1 and the operating switch 1-2 are located between the front and rear ends of the remote control handle 1. The mounting base 2 is elongated, and at least one end of the mounting base 2 is detachably connected to an end of the remote control handle 1. A detachable connection structure is provided between the detachably connected end of the mounting base 2 and the corresponding end of the remote control handle 1. When the mounting base 2 and the remote control handle 1 are connected, the grip portion 1-1 and the operating switch 1-2 are suspended above the mounting base 2, forming a gap between the mounting base surface. In this embodiment, the front and rear ends of the remote control handle are preferably detachably connected to the front and rear ends of the corresponding remote control handles.

[0025] Because the remote control handle can be detachably connected to a mounting bracket fixed to the front of the electric surfboard, the remote control handle can then be used as a handrail when connected to the mounting bracket without affecting the operation of the remote control handle. This solves the problem of existing electric surfboards where the handrail and remote control handle are separated, which is unfriendly to novice surfers. It makes it difficult for novice surfers to hold the remote control handle and the handrail with one hand at the same time, making surfing difficult for novice surfers, difficult to maintain balance, and prone to falling into the water. With this remote control handle, novice surfers can easily grasp the remote control handle as a handrail during the surfboard's launch phase while operating the remote control handle at the same time, making surfing learning more convenient, easy, and safer.

[0026] Furthermore, the front end of the remote control handle 1 and the front end of the mounting base 2 are respectively provided with matching positioning hooks 3 and limiting pins 4. Matching protrusions 5 and recesses 6 are provided between the rear end of the remote control handle 1 and the rear end of the mounting base 2. The recesses 6 are formed by a continuous, closed edge 2-1 raised from the rear end surface of the mounting base 2. When the remote control handle 1 and the mounting base 2 are connected, the positioning hook 3 hooks onto the limiting pin 4 and the protrusion 5 inserts into the recess 6. When the remote control handle 1 and the mounting base 2 are separated, the positioning hook 3 disengages from the limiting pin 4 and the protrusion 5 disengages from the recess 6. The positioning hook 3 bends outwardly and extends in a plane parallel to the extension direction of the remote control handle 1. Two symmetrical lugs 2-2 are provided on the front end surface of the mounting base 2. The limiting pin 4 is suspended above the mounting base 2 by being fixedly connected to the two lugs 2-2 at both ends, forming a gap 13 between the limiting pin 4 and the mounting base 2 below. The remote control handle 1 can be rotated to allow the positioning hook 3 to partially penetrate the gap 13 and hook the limiting pin 4. To ensure that when the mounting base 2 and the remote control handle 1 are connected, the grip portion 1-1 and the operating switch 1-2 are suspended above the mounting base 2 and there is enough space between the surface of the mounting base for fingers to pass through, such as Figure 2The lowest end surface of the positioning hook 3 and the lowest bottom surface of the protrusion 5 both protrude from the operating switch 1-2. In the figure, the end surface and bottom surface are lower than the operating switch, so that there is enough space between the operating switch and the surface of the mounting seat for the finger to pass through for operation.

[0027] During the surfboard's sliding phase, under the action of inertia, the person will lean back relative to the surfboard and pull the remote control handle. At this time, the positioning hook at the front end of the remote control handle will hook the horizontal pin, and the convex portion at the rear end of the remote control handle will tend to press downward, pressing the convex portion and the concave hole tightly.

[0028] The positioning hook 3 is composed of a vertical section 3-1 and a horizontal section 3-2 that intersect vertically. The vertical section 3-1 is fixed to the front end of the remote control handle 1 and extends outward. Two through holes 3-4 are also opened on the vertical section 3-1 for weight reduction. The vertical section 3-1 and the horizontal section 3-2 form an inner concave arc surface 3-3 on the inner surface of the connection part that can fit the limit pin 4. When the positioning hook 3 hooks the limit pin 4, the concave arc surface 3-3 is close to the side wall of the limit pin 4, and the horizontal section 3-2 penetrates into the gap 13 between the limit pin 4 and the mounting seat 2.

[0029] In order to improve the stability of the connection between the remote control handle and the mounting base and prevent shaking or even loosening between the two, a limiting structure to prevent loosening is provided between the protrusion 5 and the recessed hole 6, so that the protrusion 5 and the recessed hole 6 are limited when they are plugged into place to prevent shaking. In this embodiment, the protrusion 5 and the recessed hole 6 are respectively arranged at the rear end of the remote control handle 1 and the rear end of the mounting base 2. The limiting structure is specifically a matching protrusion 7 and recessed hole 8, which are respectively arranged on the inner wall of the recessed hole 6 and the side of the protrusion 5, and the extension direction of the protrusion 7 and the recessed hole 8 is perpendicular to the direction in which the protrusion 5 is inserted into the recessed hole 6. When the protrusion 5 and the recessed hole 6 are plugged into place, the protrusion 7 is buckled into the recessed hole 8, and when the protrusion 5 and the recessed hole 6 are disengaged, the protrusion 7 is out of the recessed hole 8.

[0030] During use, when the convex part is inserted into the concave hole, the protrusion is also buckled into the inner concave. Since the extension direction of the protrusion buckling the inner concave is perpendicular to the direction of the convex part inserting into the concave hole, it can effectively prevent the remote control handle from shaking and loosening relative to the mounting base.

[0031] In order to further improve the controllability of the remote control handle and facilitate novice users to practice using the electric surfboard, the remote control handle 1 is also provided with a speed gear switch 1-3 on the back of the operating switch 1-2. The speed gear switch 1-3 can be used to control the speed of the electric surfboard by toggling it in a straight line or rotating it back and forth, thereby limiting the speed range of the electric surfboard's water skiing. In this embodiment, the speed gear switch 1-3 is a push button that can be toggled back and forth in a straight line to adjust the two gears, such as Figure 5 and Figure 6 As shown, push the button back and forth to switch to Figure 5 The low speed gear in the middle, the low speed mark 9 is visible; when the push button is switched to Figure 6When in high gear, the high speed mark 10 is visible. Surfing too fast can be difficult for beginners. The speed throttle of the water jet mechanism can be adjusted by pressing the operating switch. In high gear, keep the speed throttle steady in the middle position. This makes it difficult for beginners to control the speed properly, and they can easily speed up or slow down, potentially falling into the water. Use the speed switch 1-3 to select between high and low speeds. Beginners can practice balancing in low gear first, making it easier for beginners to learn how to use an electric surfboard. Once you've mastered it, you can increase the speed and excitement of high gear. In low gear, beginners can safely press the operating switch all the way down. This lowers the maximum speed, making it easier to maintain speed and less likely to fall overboard. High gear is suitable for those who are already experienced.

[0032] like Figure 7 As shown, embodiment 2 is an electric surfboard, comprising a surfboard body 11 and a matching remote control handle 1. A water jet power device that can be controlled by the remote control handle 1 is provided in the surfboard body 11. Two handrails are provided at the front of the surfboard body 11. As shown in the figure, one of the two handrails is a fixed handrail 12, and the other is formed by the remote control handle 1 connected to the surfboard body 11. The remote control handle 1 is detachably connected to the surfboard body 11 using the remote control handle that can be used as an armrest as described in embodiment 1. Figure 2 As shown, the mounting base 2 is fixed to the surface of the surfboard body 11 through the mounting holes 15 provided at both ends and through which bolts can be inserted. In order to hide the exposed cap ends of the bolts, the mounting base 2 is further provided with a countersunk hole 14 coaxial with the mounting hole 15. The recessed hole 6, the countersunk hole 14 and the mounting hole 15 at the rear end of the mounting base 2 are arranged from top to bottom.

[0033] The remote control handle can be attached to the surfboard and doubles as a handrail without interfering with the operation of the remote handle. This solves the inconvenience of novice surfers having to hold both the handrail and the remote handle simultaneously, which can lead to difficulties in learning to surf, difficulty maintaining balance, and falling into the water. During the start of the surfboard, new surfers can easily grasp the remote handle as a handrail while operating it simultaneously, making surfing learning more convenient, easy, and safer.
