Description

Technical Field

[0001] This application relates to the field of boat technology, and in particular to a foldable rigid-flexible coupling bottom plate and an inflatable rescue boat having the same. Background Technology

[0002] Inflatable rescue boats are small, maneuverable boats that use an inflatable medium to form a predetermined shape and buoyancy, suitable for water rescue operations. Compared to traditional rescue boats, inflatable rescue boats are safer and feature lightweight construction, small storage space, high maneuverability, and strong safety, making them adaptable to various water rescue operations. To reduce drag during navigation, the bow of inflatable boats is typically designed to be slightly upturned; however, the maximum speed of existing inflatable rescue boats remains relatively insufficient.

[0003] Existing inflatable rescue boat floor panels are mainly divided into two categories. The first category consists of flexible floor panels made of soft materials such as rubber or PVC. These flexible floor panels can be folded along with the hull for easy carrying and storage. However, due to their softness and lack of rigidity, the boat will experience up-and-down vibration and bumping during high-speed travel. People walking on the soft floor panel are prone to collapse and swaying. Furthermore, in the harsh rescue environment of disaster areas, the flexible floor panel is easily punctured by sharp objects in the water. The second category consists of rigid floor panels made of plastic or metal. These rigid floor panels are sturdy and stable, and easy to walk on. However, they are often assembled from multiple rigid panels, which requires time and effort to assemble, reducing the installation efficiency of the inflatable boat. In addition, aluminum alloy panels are prone to bending and puncturing the boat's buoys when facing large waves, posing a safety hazard. Summary of the Invention

[0004] This application provides a foldable rigid-flexible coupling base plate and an inflatable rescue boat having the same, to at least solve one problem in the related art. The technical solution of this application is as follows:

[0005] In a first aspect, embodiments of this application provide a foldable rigid-flexible coupling base plate, comprising: a front flexible base plate and a rear rigid base plate, wherein the rear rigid base plate includes a first rigid base plate and a second rigid base plate that can be detachably connected; the front flexible base plate and the first rigid base plate are coupled together.

[0006] In some implementations, the first end of the first rigid base plate is provided with a first slot structure, and the second end of the second rigid base plate is provided with a second slot structure. The first rigid base plate and the second rigid base plate are engaged and disengaged through the first slot structure and the second slot structure.

[0007] In some implementations, the end of the second end of the second rigid base plate engages with the first slot structure, and the end of the first end of the first rigid base plate engages with the first slot structure.

[0008] In some implementations, the front flexible base plate is a flexible inflatable base plate.

[0009] In some implementations, the flexible inflatable base plate is a polyurethane rubber wire base plate.

[0010] In some implementations, the front flexible base plate and the first rigid base plate form an arc-shaped front rigid-flexible coupling base plate.

[0011] In some implementations, the first rigid base plate and the second rigid base plate are made of 5083 aluminum-magnesium alloy.

[0012] Secondly, embodiments of this application provide a foldable rigid-flexible coupling inflatable rescue boat, comprising: a hull and the foldable rigid-flexible coupling bottom plate described in the first aspect, wherein the foldable rigid-flexible coupling bottom plate is installed on the bottom of the hull.

[0013] In some implementations, the front flexible bottom plate is connected to the front side of the hull by a fixed sleeve, and the rear rigid bottom plate is inserted into the lower side of the airbag of the hull.

[0014] The technical solution provided in this application has at least the following beneficial effects:

[0015] A rigid-flexible coupling bottom plate is achieved by coupling a front flexible bottom plate and a rear rigid bottom plate, and a foldable rigid-flexible coupling bottom plate is achieved by connecting a first rigid bottom plate and a second rigid bottom plate that can be detachably connected. During movement, the rear rigid bottom plate can improve stability and puncture resistance, and can shift the center of gravity of the boat to the rear, causing the bow to tilt upwards during movement, reducing the contact area between the hull and the water surface, reducing water resistance, and increasing the maximum speed. This solves the problems of insufficient rigidity of the flexible rescue boat bottom plate in the prior art, which leads to swaying, instability, and easy puncture, as well as the problems of low installation efficiency, large weight, inconvenient transportation and storage, and relatively insufficient maximum speed of the rigid rescue boat bottom plate.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0024] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0025] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0026] like Figures 1 to 4 As shown, this application provides a foldable rigid-flexible coupling base plate. (Refer to...) Figure 1 The foldable rigid-flexible coupling base plate includes a front flexible base plate 1 and a rear rigid base plate. The rear rigid base plate includes a first rigid base plate 2 and a second rigid base plate 3 that can be detachably connected. The front flexible base plate 1 and the first rigid base plate 2 are coupled together. The front flexible base plate 1 and the first rigid base plate 2 coupled together form the front rigid-flexible coupling base plate 6.

[0027] The foldable rigid-flexible coupling bottom plate of this application embodiment achieves rigid-flexible coupling by coupling a front flexible bottom plate and a rear rigid bottom plate, and achieves foldability by detachably connecting a first rigid bottom plate and a second rigid bottom plate. During movement, the rear rigid bottom plate can improve stability and puncture resistance, and can shift the center of gravity of the boat aft, causing the bow to tilt upwards during movement, reducing the contact area between the boat and the water surface, reducing water resistance, and increasing the maximum speed. It solves the problems of insufficient rigidity of the flexible rescue boat bottom plate in the prior art, which leads to swaying, instability, and easy puncture, as well as the problems of low installation efficiency, large weight, inconvenient transportation and storage, and relatively insufficient maximum speed of the rigid rescue boat bottom plate.

[0028] In some embodiments, such as Figure 2 As shown, the first rigid base plate 2 has a first slot structure 4 at its first end, and the second rigid base plate 3 has a second slot structure 5 at its second end. The first rigid base plate 2 and the second rigid base plate 3 can be engaged and disengaged through the first slot structure 4 and the second slot structure 5.

[0029] Therefore, the first rigid base plate 2 and the second rigid base plate 3 can be detachably connected through the sliding slots achieved by the first slot structure 4 and the second slot structure 5. The front rigid-flexible coupling base plate 6 and the second rigid base plate 3 can be quickly separated and folded through the sliding slots, thereby achieving the rapid separation and folding of the front rigid-flexible coupling base plate 6 and the second rigid base plate 3. The structure is simple, easy to assemble and disassemble, and has high strength and stability.

[0030] In some embodiments, the end of the second end of the second rigid base plate 3 engages with the first slot structure 4, and the end of the first end of the first rigid base plate 2 engages with the first slot structure 4.

[0031] Therefore, it is easy to assemble and disassemble, has a simple structure, and is easy to implement.

[0032] In some embodiments, the front flexible base plate 1 is a flexible inflatable base plate.

[0033] Therefore, as Figure 4 As shown, the flexible inflatable base plate can be folded after deflation during disassembly, taking up little space and making it convenient for transportation.

[0034] In some embodiments, the flexible inflatable base plate is a polyurethane rubber wire base plate.

[0035] Therefore, the tensile strength and wear resistance of the flexible inflatable base plate are improved by using polyurethane rubber material to draw the base plate.

[0036] In some embodiments, the first rigid base plate 2 and the second rigid base plate 3 are made of 5083 aluminum-magnesium alloy.

[0037] Therefore, by using 5083 aluminum-magnesium alloy material, the corrosion resistance of the first rigid base plate 2 and the second rigid base plate 3 is improved.

[0038] In some embodiments, such as Figure 3 As shown, the front flexible base plate 1 and the first rigid base plate 2 form an arc-shaped front rigid-flexible coupling base plate 6.

[0039] Therefore, the curved front rigid-flexible coupling bottom plate 6 is adapted to the hull of the inflatable rescue boat, reducing drag and increasing maximum speed.

[0040] Based on the above embodiments, this application also provides a foldable rigid-flexible coupling inflatable rescue boat, including: a hull and a foldable rigid-flexible coupling bottom plate as described in the above embodiments, wherein the foldable rigid-flexible coupling bottom plate is installed on the bottom of the hull.

[0041] The foldable rigid-flexible coupling inflatable rescue boat of this application improves the stability and puncture resistance of the inflatable rescue boat's bottom plate by adopting the foldable rigid-flexible coupling bottom plate of the above embodiment. It can also shift the center of gravity of the boat to the rear, causing the bow to tilt upwards during operation, reducing the contact area between the hull and the water surface, reducing water resistance, and increasing the maximum speed. It solves the problems of insufficient rigidity of the flexible rescue boat bottom plate in the prior art, which leads to swaying, instability, and easy puncture, as well as the problems of low installation efficiency, heavy weight, inconvenient transportation and storage, and relatively insufficient maximum speed of the rigid rescue boat bottom plate.

[0042] In some embodiments, the front flexible bottom plate 1 is connected to the front side of the hull by a fixed sleeve, and the rear rigid bottom plate is inserted into the lower side of the airbag of the hull.

[0043] Therefore, the foldable rigid-flexible coupling base plate is easy to install and disassemble.

[0044] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

[0045] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
