Description

Technical Field

[0001] This utility model relates to the field of automotive floor technology, and in particular to an automotive floor. Background Technology

[0002] The car floor is a fundamental component of the vehicle's interior structure. It protects passengers inside the cabin from road impacts while also bearing the weight of the occupants.

[0003] The longitudinal beams at the bottom of the floor are designed to meet collision performance requirements, as shown in the attached document. Figure 1 During a collision, the longitudinal beam tends to open in the Y direction, so it is often necessary to install a reinforcing plate 4 inside the longitudinal beam 3 to hold the opening of the longitudinal beam 3 in the Y direction, which is not conducive to reducing manufacturing costs.

[0004] For example, CN104002874A, published on August 27, 2014, discloses a double H-shaped floor structure specifically for pure electric vehicles, made of aluminum alloy, including a front floor. Its features include: reinforcing ribs on the front floor; the front floor being fixed to the rear sections of the left and right longitudinal beams, with the left and right longitudinal beams located on either side of the bottom of the front floor; a front seat mounting reinforcement beam on the front floor; a central channel reinforcement plate on the central axis of the floor structure; a floor crossbeam at the front end; and a middle floor front support plate at the rear end. However, in the case of a collision, the longitudinal beams on the floor are prone to deformation, resulting in low overall strength and poor practicality of the vehicle floor. Summary of the Invention

[0005] The purpose of this invention is to provide a stronger automotive floor. This invention uses transverse ribs on the base plate to hold the longitudinal beams on both sides, thus preventing the longitudinal beams from opening and ensuring they do not bend in the area in contact with the base plate. This improves the strength of the automotive floor and enhances its practicality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: an automotive floor, including a base plate, a reinforcing rib on one side of the base plate, a longitudinal beam on the other side of the base plate, and a transverse rib connected to the reinforcing rib on the base plate, the transverse rib contacting the longitudinal beam.

[0007] The length direction of the transverse rib is the same as that of the vehicle's y-direction.

[0008] The reinforcing ribs are arc-shaped, and the longitudinal beams are also arc-shaped.

[0009] The adjacent transverse ribs are arranged parallel to each other.

[0010] The longitudinal beam has a U-shaped cross-section and a U-shaped groove. An extension plate is provided at the opening of the U-shaped groove of the longitudinal beam, and the extension plate is welded to the base plate.

[0011] The longitudinal beam is provided with a reinforcing protrusion at the bend, and the reinforcing protrusion is set in the U-shaped groove.

[0012] The beneficial effects of this utility model are:

[0013] By adding transverse ribs to increase the strength of the reinforcing ribs, the strength of the floor plate is increased. When a car collides, the longitudinal beams on the floor plate deform, and the transverse ribs hold the longitudinal beams on both sides, thus preventing the longitudinal beams from opening and preventing them from bending in the area in contact with the floor plate. This improves the strength performance and protects the occupants. In addition, the entire car floor plate structure is simple, has low manufacturing cost, and is more practical.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figure 1 As shown, the car floor includes a base plate 1. A reinforcing rib 2 is provided on one side of the base plate 1, and a longitudinal beam 3 is provided on the other side of the base plate 1. A transverse rib 5 connected to the reinforcing rib 2 is provided on the base plate 1. Specifically, the transverse rib 5 is located at the position where the longitudinal beam 3 overlaps with the base plate 1. The transverse rib 5 is perpendicular to the longitudinal beam 3, thereby ensuring that the transverse rib 5 stably reinforces the longitudinal beam 3. In this embodiment, the width of the reinforcing rib 2 and the transverse rib 5 is 30mm. By increasing the width of the ribs, the comfort of the driver and passengers' feet is ensured.

[0020] In use, the strength of the reinforcing ribs 2 is increased by setting the transverse ribs 5, thereby increasing the strength of the base plate 1. When a car collides, the longitudinal beams 3 on the base plate 1 deform. The transverse ribs 5 hold the longitudinal beams 3 in place on both sides, preventing the longitudinal beams 3 from opening and ensuring that the longitudinal beams 3 do not bend in the area in contact with the base plate 1. This improves the strength performance and protects the occupants. Compared to... Figure 2 The existing longitudinal beam 3 shown is equipped with a reinforcing plate 4. The structure in this application is simpler, has lower manufacturing cost, and is more practical.

[0021] Reference Figure 1 The transverse rib 5 has the same length direction as the y-direction of the car, thus ensuring that when the base plate 1 deforms in the X-direction during a car collision, the longitudinal beam 3 is prevented from deforming by the transverse rib 5, thereby making the base plate 1 stronger.

[0022] Specifically, the reinforcing rib 2 is arc-shaped, and the longitudinal beam 3 is arc-shaped, thereby ensuring that the longitudinal beam 3 and the transverse rib 5 on the reinforcing rib 2 are in contact. In this embodiment, there are two reinforcing ribs 2, which are symmetrically distributed.

[0023] Adjacent transverse ribs 5 are arranged parallel to each other, thereby achieving a uniform strength distribution at different locations of the base plate 1. Furthermore, in this embodiment, referring to... Figure 1 The length of the transverse reinforcement 5 increases uniformly from one side of the base plate 1 to the other side.

[0024] The longitudinal beam 3 has a U-shaped cross section and a U-shaped groove. An extension plate 6 is provided at the opening of the U-shaped groove of the longitudinal beam 3. The extension plate 6 is welded to the base plate 1. The extension plate 6 increases the welding area between the longitudinal beam 3 and the base plate 1, thereby ensuring a stable connection between the longitudinal beam 3 and the base plate 1.

[0025] The longitudinal beam 3 has a reinforcing protrusion 7 at the bend. The reinforcing protrusion 7 is set in the U-shaped groove. The reinforcing protrusion 7 increases the strength of the longitudinal beam 3, thereby increasing the strength of the car floor. Specifically, the reinforcing protrusion 7 is set on the inner side wall of the U-shaped groove.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
