Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a shock-absorbing and lightweight carbon fiber seat for boats. Background Technique

[0002] With the development of the economic society, the living standards and quality of the people have been continuously improved. Boats are widely used in national defense, civil use, production or life, and people have higher and higher requirements for the weight and quality of boat seats.

[0003] When a boat is operating, it sways and heaves continuously under external impact forces, and the boat seat will also shake accordingly. If a passenger sits on a heavy and non-shock-absorbing seat for a long time, it will not only make people tired, but also may pose a safety hazard. Therefore, the existing boat seats need to be improved. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the utility model provides a shock-absorbing and lightweight carbon fiber seat for boats, which is light in weight, occupies less floor space, has a good comfortable riding experience, reduces the amount of vibration and extends the service life.

[0005] In order to achieve the above purpose, the utility model provides a shock-absorbing and lightweight carbon fiber seat for boats, including a seat cushion; a backrest is connected to the rear side of the upper end surface of the seat cushion, and a base is arranged on the lower end surface of the seat cushion; a Z-shaped pressure-bearing frame is fixedly connected between the upper end surface of the base and the lower end surface of the seat cushion; hydraulic shock-absorbing components are fixed at both ends of the Z-shaped pressure-bearing frame through first fasteners; the hydraulic shock-absorbing components include a working cavity and a piston rod; one end of the piston rod extends into the working cavity and can move telescopically in the working cavity; there is flowing hydraulic oil in the working cavity, and a piston is connected to the end of the piston rod extending into the working cavity; when the piston rod pushes the piston to move telescopically, the hydraulic oil flows up and down in the working cavity.

[0006] The seat cushion of the seat is elastic and soft, increasing the comfortable riding experience of passengers. The seat is provided with hydraulic shock-absorbing components on the Z-shaped pressure-bearing frame. When the seat is subjected to external forces or impact forces, the piston rod drives the piston to move up and down, and the hydraulic oil enters and exits the piston. The hydraulic oil consumes kinetic energy when moving in the working cavity, converting the kinetic energy of mechanical impact into heat energy, thereby absorbing and reducing the mechanical impact and vibration of the seat, playing a role in protecting the seat, improving the comfort of the seat, increasing the riding safety and extending the service life of the seat.

[0007] Furthermore, mounting plates are arranged on both the upper end surface and the lower end surface of the Z-shaped pressure-bearing frame, and both ends of the hydraulic shock-absorbing components are respectively fixed on the mounting plates through a set of first fasteners. Fixing both ends of the hydraulic shock-absorbing components on the mounting plates through first fasteners plays a fixing role.

[0008] Furthermore, a pair of support inclined planes with openings are arranged in the middle of the Z-shaped pressure-bearing frame; the hydraulic shock-absorbing assembly penetrates through the openings of the support inclined planes. The provision of a pair of support inclined planes can enhance the pressure-bearing effect of the Z-shaped pressure-bearing frame; openings are provided on the support inclined planes to facilitate the passage of the hydraulic shock-absorbing assembly and its installation on the end faces of the Z-shaped pressure-bearing frame.

[0009] Furthermore, a leg support pad is provided on the front side of the seat cushion; the upper end of the leg support pad forms a leg support arc surface, and the highest point of the leg support arc surface is higher than the upper end surface of the seat cushion; leg extension areas are formed on both sides of the leg support arc surface. When a passenger sits on the seat, the leg support arc surface can place and support the thigh area; when the boat is impacted, the leg support arc surface higher than the upper end surface of the seat cushion can play a buffering role to prevent the passenger from falling; during the ride, the passenger can naturally place the lower leg area along the leg extension area or lean the lower leg area against the leg extension area to improve the riding comfort.

[0010] Furthermore, the end face of the base is of a concave notch structure. Setting the end face of the base as a concave notch saves more materials, has a smaller volume, occupies less floor space, and the seat is lighter in weight.

[0011] Furthermore, multiple groups of mounting holes are provided on the lower end face of the Z-shaped pressure-bearing frame; each group of mounting holes has different specifications. The provision of multiple groups of mounting holes with different specifications on the lower end face of the Z-shaped pressure-bearing frame can meet the installation of various bases, making it more flexible and convenient.

[0012] Furthermore, after the second fastener passes through the mounting hole, the upper end face of the base is detachably connected to the lower end face of the Z-shaped pressure-bearing frame. The passenger can disassemble the base at any time according to their own needs. After disassembling the base, it will not affect the load-bearing effect and riding experience of the seat, which is convenient for children to ride and leave the seat at any time. After disassembling the base, the seat is lighter in weight; if not disassembled, a footrest can also be installed on the base to facilitate the passenger to place their feet and increase the riding comfort experience.

[0013] Furthermore, the base is provided with a hollow; the hollow part of the base forms a storage compartment. The provision of a storage compartment in the hollow position of the base not only facilitates the passenger to store luggage but also does not occupy extra space, with a clever design.

[0014] Furthermore, a handle is provided at the top of the backrest. The handle facilitates the passenger to drag and move the seat.

[0015] Furthermore, the seat is made of carbon fiber material and has a total weight of 22 - 24 kg. The seat cushion is elastically soft, enhancing the passengers' riding comfort experience. The seat is made of raw carbon fiber material, with excellent properties such as low specific gravity, high strength, good elastic modulus, corrosion resistance, and chemical resistance, making it particularly suitable for manufacturing lightweight seats for light high-speed boats. The carbon fiber material does not rust, does not require peeling of the coating, can prevent ultraviolet radiation, and the seat does not fade.

[0016] Beneficial effects

[0017] In the present utility model, a hydraulic shock absorber assembly is installed on the Z-shaped pressure-bearing frame of the seat. When the seat is subjected to external force or impact, the hydraulic oil moves in the working chamber to consume kinetic energy, converting the kinetic energy of mechanical impact into heat energy, thereby absorbing and reducing the mechanical impact and vibration of the seat, playing a role in protecting the seat, improving the comfort of the seat, and extending the service life of the seat.

[0018] Using carbon fiber material for the boat seat, the hollow part of the base is set as a storage compartment, and the base can also be disassembled according to needs. The seat occupies less floor space, is small in size, lightweight, and the seat is elastically soft, facilitating the storage of luggage, and is particularly suitable for light high-speed boats.
