Description

Technical Field

[0001] This invention relates to the field of inflatable boat technology, and in particular to a collision-resistant inflatable boat. Background Technology

[0002] Water tourism and rafting both require the use of boat equipment. Because inflatable boats are lightweight, can be used simply by inflating, and can be deflated to reduce their size and make them easy to carry, they have become the preferred boat equipment for tourism enthusiasts.

[0003] Traditional inflatable boats typically lack anti-collision structures, making them vulnerable to damage from impacts. To address this issue, some manufacturers have designed inflatable boats with anti-collision structures. For example, Chinese Patent Publication No. CN210971469U discloses an inflatable boat comprising a hull, a seat at the bottom of the hull, a power unit at the stern, and an anti-collision device at the front. This device includes a housing with a first spring fixedly connected to its inner wall. A pad is attached to the end of the first spring, and the pad is fixedly connected to the anti-collision block. The anti-collision block penetrates the front of the housing and extends into the housing, with a limiting protrusion at the end of the anti-collision block extending into the housing. This inflatable boat, with its anti-collision device at the front, can keep the inflatable boat away from walls or obstacles when approaching shore or accidentally encountering obstacles, buffering the impact and protecting the bow from damage. Buffer devices are also located on both sides of the hull, combining the elastic force of an airbag and a second spring to further buffer the impact and protect the hull from damage.

[0004] The aforementioned inflatable boat has anti-collision devices installed at the front and sides of the airbag on the hull to avoid collisions with the shore or tall obstacles. However, this structure can only prevent collisions with obstacles within the visible range. It is not effective against obstacles in the water, such as rocks that have not yet fully emerged from the water. Furthermore, after the airbag is deflated, the anti-collision structure still occupies a certain amount of space, making it inconvenient to store and carry.

[0005] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a collision-resistant rubber boat to solve the problem that the existing rubber boats are not effective in protecting against obstacles in the water.

[0007] A collision-resistant rubber boat includes a hull and an airbag disposed on the upper edge of the hull. The hull includes a fiberglass bottom, a fiberglass deck fixed to the upper end of the fiberglass bottom, and a highly elastic pad layer fixed to the lower end of the fiberglass bottom. An inclined guide surface is provided on the bottom of one side of the bow of the hull, and the guide surface is provided with a collision-resistant structure.

[0008] Specifically, the anti-collision structure includes a mounting plate fixed to the guide surface, two sliders fixed to the mounting plate, a slide rail that slides with the two sliders, and an anti-collision plate fixed to one end of the slide rail. The anti-collision plate has an arc-shaped structure.

[0009] Specifically, the anti-collision structure also includes two springs disposed within the slide rail, with the two springs respectively connected to the ends of the two sliders.

[0010] Specifically, the lower end of the highly elastic padding layer is covered with a waterproof and wear-resistant fabric.

[0011] Specifically, a hollow groove is formed at the upper end of the highly elastic pad.

[0012] Specifically, a cabin is provided between the fiberglass hull bottom and the fiberglass deck, and the cabin is provided with several reinforcing ribs.

[0013] Specifically, the airbag includes, from the inside out, an air layer, a waterproof inner layer, a rubber layer, and a puncture-resistant layer.

[0014] Specifically, the anti-puncture layer is a graphene aerogel fiber fabric.

[0015] Specifically, a seat cushion is installed on the upper part of the fiberglass deck, and multiple handles are provided on the airbag.

[0016] Specifically, a water deflector is provided on one side of the stern of the hull, and a pedal mechanism is provided on the water deflector. The pedal mechanism includes a rotation drive device fixed to the fiberglass deck and an L-shaped plate connected to the output end of the rotation drive device. The L-shaped plate can be rotated to switch between a diving pedal and a boarding pedal.

[0017] The beneficial effects of this invention are:

[0018] The anti-collision inflatable boat of the present invention adds a highly elastic padding layer to the bottom of the fiberglass boat. When the bottom of the inflatable boat collides with an obstacle in the water, the highly elastic padding layer can quickly deform elastically to absorb the impact energy, prevent the impact force from being transmitted to the inflatable boat, slow down the collision speed, and thus reduce the damage caused by the collision. By providing an inclined flow guide surface at the bottom of the bow side of the hull, and the flow guide surface is equipped with an anti-collision structure, the bottom of the bow side of the hull is protected by the anti-collision structure, reducing the damage to the bottom of the hull caused by the collision.

Detailed Implementation

[0028] This invention provides a collision-resistant inflatable boat. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0029] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0030] like Figures 1 to 8 This embodiment discloses an anti-collision rubber boat, including a hull 10 and an airbag 20 disposed on the upper edge of the hull 10. The hull 10 includes a fiberglass bottom 11, a fiberglass deck 12 fixed to the upper end of the fiberglass bottom 11, and a highly elastic padding layer 13 fixed to the lower end of the fiberglass bottom 11. An inclined guide surface 14 is provided at the bottom of the bow side of the hull 10, and the guide surface 14 is provided with an anti-collision structure 30.

[0031] The anti-collision rubber boat of this embodiment uses a fiberglass bottom 11 and a fiberglass deck 12 for the hull 10. Fiberglass has high strength and light weight, which can improve the structural stability and portability of the hull 10; moreover, it has good corrosion resistance and can resist the erosion of humidity, chemicals and other environmental factors, and will not corrode, rust or decay.

[0032] A high-elasticity pad 13 is added to the lower end of the fiberglass bottom 11. The high-elasticity pad 13 has toughness and memory properties, which can absorb, delay and eliminate impact energy, and can rebound to its initial shape after impact. When the bottom of the rubber boat collides with an obstacle in the water, the high-elasticity pad 13 can quickly deform elastically, absorb impact energy, prevent the impact force from being transmitted to the rubber boat, slow down the collision speed, and thus reduce the damage caused by the collision.

[0033] The high-elasticity pad 13 can be made of polyurethane, rubber, or polyethylene foam materials, which have toughness and memory properties, can absorb, delay, and eliminate impact energy, and can rebound to its initial shape after impact. In addition, since the bottom of the rubber boat needs to be immersed in water for a long time, in order to prevent the high-elasticity pad 13 from being corroded, some anti-corrosion coatings, such as epoxy resin coatings, or waterproof coatings, such as acrylic waterproof coatings, can be applied to the lower surface of the high-elasticity pad 13 to effectively improve the corrosion resistance and waterproofing of the lower surface of the high-elasticity pad 13.

[0034] Additionally, since inflatable rafts are generally propelled forward, the bottom can easily be scratched by hidden obstacles such as rocks in the sea or rafting channel. To avoid this, please refer to [the relevant guidelines / guidelines]. Figure 3 and Figure 6 In this embodiment, an inclined guide surface 14 is provided at the bottom of the bow side of the hull 10 to reduce resistance during normal movement. The guide surface 14 is provided with an anti-collision structure 30, which protects the bottom of the bow side of the hull 10 and reduces damage to the bottom of the hull 10 caused by collision.

[0035] For further details, please refer to... Figure 5 and Figure 7 As shown, the anti-collision structure 30 of this embodiment includes a mounting plate 31 fixed to the guide surface 14, two sliders 32 fixed to the mounting plate 31, a slide rail 33 that slides with the two sliders 32, and an anti-collision plate 34 fixed to one end of the slide rail 33. When the rubber boat encounters an obstacle in the water during its movement, the anti-collision plate 34 first contacts the obstacle. Since the slide rail 33 is provided at the end of the anti-collision plate 34 facing the hull 10, the two sliders 32 can slide along the slide rail 33, thereby changing the direction of travel of the hull 10 and preventing the hull 10 from hitting the obstacle directly, thereby reducing the damage caused by the collision. After the hull 10 changes direction, under the action of centrifugal inertia, it drives the anti-collision plate 34 to gradually separate from the obstacle, thus completing the collision separation.

[0036] In addition, in order to reduce the resistance at the front of the hull 10, the guide surface 14 is usually designed as an arc-shaped structure. In order to adapt to the structure of the guide surface 14, the anti-collision plate 34 in this embodiment is also an arc-shaped structure. The anti-collision plate is made of a material with high hardness, such as fiberglass, stainless steel plate, aluminum alloy plate, titanium alloy plate, etc.

[0037] Furthermore, the slide rail 33 and the anti-collision plate 34 can be designed as detachable and installable structures, specifically using bolts and nuts for installation and fixation, facilitating user disassembly and replacement. Of course, using bolts and nuts for fixation is only one preferred implementation method. In other embodiments, screws, clips, threaded connections, etc., can also be used, and it is not limited to bolts and nuts for fixation.

[0038] Please refer to Figure 5 and Figure 7 The anti-collision structure 30 in this embodiment also includes two springs 35 disposed in the slide rail 33. The two springs 35 are respectively connected to the ends of the two sliders 32. Through the elastic action of the two springs 35, the anti-collision plate 34 can automatically reset after the collision.

[0039] Please refer to Figure 4 The lower end of the high-elasticity pad 13 is covered with a waterproof and wear-resistant fabric 15. The waterproof and wear-resistant fabric 15 includes a polypropylene base fabric and a waterproof coating on the surface of the polypropylene base fabric. The polypropylene base fabric has good waterproof and wear-resistant properties, and the waterproof coating can greatly improve its waterproof ability.

[0040] Please refer to Figure 5 A hollow groove 16 is formed at the upper end of the high elastic pad 13 to provide a space for the high elastic pad 13 to deform elastically. When the bottom of the hull 10 is hit, the high elastic pad 13 can quickly deform elastically and squeeze the space of the hollow groove 16, thus achieving a good anti-collision effect.

[0041] Please refer to Figure 4 In this embodiment, a cabin 17 is provided between the fiberglass bottom 11 and the fiberglass deck 12. Some openings can be provided on the fiberglass deck 12 to load items such as oars and life jackets into the cabin 17. In addition, in order to strengthen the structural strength of the hull 10, several reinforcing ribs 18 are provided in the cabin 17. The reinforcing ribs 18 can be set at an angle to support the fiberglass deck 12 and prevent the fiberglass deck 12 from sinking.

[0042] Please refer to Figure 4 and Figure 5The airbag 20 in this embodiment includes an air layer 21, a waterproof inner layer 22, a rubber layer 23, and a puncture-resistant layer 24 arranged sequentially from the inside to the outside. By providing the waterproof inner layer 22, the waterproof sealing capability of the airbag 20 can be improved. By providing the puncture-resistant layer 24, the airbag 20 can be prevented from being punctured by sharp obstacles.

[0043] The waterproof inner layer 22 uses a polyurethane waterproof coating to improve the waterproof sealing effect of the air layer 21; the anti-needle-puncture layer 24 is made of graphene aerogel fiber fabric, which refers to a fabric woven from graphene aerogel fibers, and has good flexibility and high tensile strength.

[0044] Please refer to Figure 1 and Figure 2 A seat cushion 19 is installed on the upper end of the fiberglass deck 12, and multiple handles 25 are provided on the airbag 20 for the convenience of users.

[0045] A water deflector 110 is provided on one side of the stern of the hull 10. A footboard mechanism 40 is provided on the water deflector 110. The footboard mechanism 40 includes a rotation drive device 41 fixed to the fiberglass deck 12 and an L-shaped plate 42 connected to the output end of the rotation drive device 41. The L-shaped plate 42 has two surfaces for users to step on, one of which is a diving footboard surface. Figure 1 The upper part is shown; the other is the boarding platform, located on the back of the diving platform. The L-shaped plate 42 can be rotated to switch between a diving platform and a boarding platform. When the user needs to board the boat, the rotation drive device 41 rotates the L-shaped plate 42 90° so that the boarding platform faces upward. The L-shaped plate 42 has a stepped structure for the user to step on, making it convenient for the user to board the boat. When the user needs to use the diving function, he / she directly steps on the boarding platform to perform the diving action, realizing the multi-functional conversion.

[0046] Of course, the diagram only shows the structure of the rotation drive device 41. Since the rubber boat is used in a water scenario, a waterproof cover (not shown) needs to be installed on the water deflector 110 to protect the rotation drive device 41 from water. In addition, the rotation drive device 41 can be a motor and equipped with a battery to power the motor.

[0047] It should be noted that the rotation drive device 41 can also be replaced with a structure that can be fixed at an angle by manual flipping. For example, a rotating shaft can be used as the rotation axis, and the mounting holes and bolts can be used as the fixing structure. After rotating to adjust the angle, the L-shaped plate 42 can be fixed by bolts in the corresponding mounting holes. This eliminates the need for electric motors and other electric devices, thus avoiding leakage.

[0048] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
