This utility model relates to the field of automotive seat technology, specifically disclosing a side panel structure for an automotive seat cushion based on TRB technology, including a side panel, a seat basin (P), an adjuster (W), a connecting shaft (X), and a connecting rod (Y). The side panel is characterized by comprising two side panels of a seatbelt side panel (Z1) and a regular side panel (Z2), or two side panels of a pair of regular side panels (Z2). This utility model features a scientific design, employing differential thickness plate technology to reduce the thickness of the seat cushion side panel, resulting in a reasonable structure, safe and reliable operation, durability, and ideal weight reduction.

The application relates to the technical field of floor type handcart, and discloses a guide rail suitable for a floor type handcart, which comprises a guide rail plate for placing a guide rail on the top surface, two groups of C-shaped beams made of resin-based composite materials are installed on the two sides of the top surface of the guide rail plate, each group of the C-shaped beams is composed of two beam bodies, two beam bodies of one group of the C-shaped beams face away from each other to form a guide rail, two groups of the C-shaped beams form two guide rails symmetrically on the top surface of the guide rail plate, limit columns are symmetrically arranged at the edges close to the two sides of the guide rail plate on the side edges of the two C-shaped beams, an oval opening is formed at the front end of the top surface of the guide rail plate, and a strip-shaped opening is also formed at the rear end of the top surface of the guide rail plate. The tensile strength of polyether ether ketone (PEEK) based carbon fiber composite material can be more than 2200 MPa; the density of the PEEK based carbon fiber composite material is only about 1.6 g / cm 3 , a significant weight reduction effect is achieved, the guide rail has the comprehensive advantages of high strength and light weight, and the convenience of carrying and using of operation and maintenance personnel is greatly improved.

This invention provides a composite material integral fuel tank structure with an integrated central wing, comprising: an upper wall panel, a lower wall panel, and a box-section frame; the box-section frame includes: a front beam, a rear beam, and several box-section ribs; the front beam and rear beam are placed side-by-side in parallel; several box-section ribs are installed side-by-side in parallel between the front beam and the rear beam, forming the box-section frame; the upper wall panel is installed on top of the box-section frame; the lower wall panel is installed at the bottom of the box-section frame; each pair of adjacent box-section ribs, along with the front beam, rear beam, upper wall panel, and lower wall panel, forms a closed space, which serves as one oil storage chamber of the integral fuel tank; several oil storage chambers are arranged side-by-side along the length direction of the upper wall panel / lower wall panel / box-section frame. This invention, through the rational design of the central wing frame and skin, can significantly reduce the risk of fuel tank leakage while reducing structural weight, and has good versatility.
