RU51583U1 - REAR PART OF A BODY OF A PASSENGER CAR - Google Patents

Abstract

The utility model relates to the field of transport engineering, namely to the structures of the rear of the body in the area of the luggage compartment of the car, in particular passenger. The objective of the utility model is aimed at reducing the complexity of manufacturing while increasing the rigidity of the node, as well as reducing material consumption. The rear part of the body part of the body contains the floor panel 1, made of metal by stamping. The floor panel 1 is a single part, which is the forming element of the rear of the body. In the center of the panel 1, a hole 2 is made under the niche of the spare wheel. A stiffener 3 is located along the edge of the hole 2, repeating the contour of this hole and made in the form of a semicircle. Stiffening ribs 4 come out of the rib 3, made in plan straight and parallel to each other with a transverse orientation relative to the axis of the car. In cross section, stiffeners 3, 4 have the shape of a sphere-shaped punching. Since the floor panel 1 is a forming element, rectangular punching 5, 6 with landing holes are made for mounting the brackets for child safety belts and weights, the main silencer bracket, respectively, and the trapezoidal stamping 7 with radius rounding is designed to place a warning triangle. For the possibility of transportation and installation on the car body in the surface of the floor panel 1, the base holes 8 are made, intended to be gripped by a manipulator, the pins of which are inserted into these holes.

Description

The utility model relates to the field of transport engineering, namely to the structures of the rear of the body in the area of the luggage compartment of the car, in particular passenger.

A technical solution is known for the rear part of the car body (see. "VAZ-2110, 2111, 2112 spare parts catalog and their modifications", M., Wheel, 2000, p. 192 - prototype), comprising a panel a floor structurally consisting of the following elements: left and right floor panels, left and right extensions, left and right side members, a fully-stamped niche for the spare wheel.

The disadvantages of the above design solution is the presence of a large number of welded parts, which increases the material consumption of the node, and also increases the complexity of manufacturing due to the large number of connecting seams.

The objective of the utility model is to reduce the complexity of manufacturing while increasing the rigidity of the node, as well as reducing material consumption.

To solve this problem, the rear part of the car body is proposed, containing a floor panel made of metal by stamping, which is a single part and is

one of the forming elements of the rear of the body. In the center of the panel, a hole is made for a niche of a spare wheel, along the contour of which there is a stiffener with stiffeners coming out of it, made in plan straight and parallel to each other with their transverse orientation relative to the axis of the car. In cross section, the stiffeners are in the form of a sphere-shaped punching.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation on the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition - “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, feasibly, reproducibly, and therefore meets the patentability condition - “industrial applicability”.

The essence of the technical solution is shown in the drawings:

Figure 1 - General view of the node;

Figure 2 - section aa.

The rear part of the body part of the body contains the floor panel 1, made of metal by stamping. The floor panel 1 is a single part and is one of the forming elements of the rear of the body. In the center of the panel 1, a hole 2 is made for a niche

spare wheel. A stiffener 3 is located along the edge of the hole 2, repeating the contour of this hole and made in the form of a semicircle. Stiffening ribs 4 come out of the rib 3, made in plan straight and parallel to each other with a transverse orientation relative to the axis of the car. In cross section, stiffeners 3, 4 have the shape of a sphere-shaped punching.

Since the floor panel 1 is a forming element, rectangular punching 5, 6 with landing holes are made for mounting the brackets for child safety belts and weights, the main silencer bracket, respectively, and the trapezoidal stamping 7 with radius rounding is designed to place a warning triangle. For the possibility of transportation and installation on the car body in the surface of the floor panel 1, the base holes 8 are made, designed to be captured by a manipulator, the pins of which are inserted into these holes.

Due to the fact that the floor panel 1 is made as a single part, it allows to reduce the complexity and material consumption of the manufacturing site, and the presence and location of stiffeners 3, 4 allows to increase the rigidity of the structure.
