Description

Technical Field

[0001] The invention belongs to the technical field of automobile floors, and in particular relates to an automobile floor panel and an automobile floor. Background Art

[0002] The sound radiation of the floor panel is the main source of road noise (within 500Hz). The quality of the floor panel design directly affects the road noise performance of the entire vehicle. Studies have shown that if the floor panel design is poor, even if enough body damping is arranged on the floor panel to suppress vibration, the final road noise performance of the entire vehicle is difficult to meet the requirements.

[0003] The existing floor panels usually use rectangular ribs to increase rigidity, which has the following problems:

[0004] 1) Rectangular ribs generally extend horizontally or vertically and are parallel to the base surface, which makes it impossible to transmit both horizontal and vertical excitations at the same time, resulting in greater vibration of the floor panel and poor road noise performance of the vehicle;

[0005] 2) Due to the constraints of formability, the vertical height of rectangular ribs generally does not exceed 8mm, which has limited effect on the stiffness of the floor panel;

[0006] 3) The rectangular ribs are generally raised vertically upward relative to the base surface of the floor panel. Since the floor panel is generally thin (0.7mm or 0.65mm), it is easy for operators to deform the reinforcing ribs during the actual production process, and the stiffness of the floor panel cannot be effectively improved.

The area where the floor panel is welded with other parts has a higher rigidity, which prevents the reinforcing rib from being deformed by being stepped on by operators during actual production;

[0059] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0060] The directions in this application are consistent with the directions of the vehicle when it is driving normally, the front-to-back direction is the longitudinal direction, the left-to-right direction is the transverse direction, and the up-down direction is the vertical direction. The transverse outer side refers to the side of the corresponding structure away from the left-right center dividing plane of the vehicle, and the transverse inner side refers to the side of the corresponding structure close to the left-right center dividing plane of the vehicle.

[0061] The automobile floor comprises a floor beam frame 2 and a floor panel 1, such as Figure 3 As shown, the floor beam frame 2 includes a floor cross beam, a floor longitudinal beam and a floor side beam, the floor cross beam includes a floor front cross beam 211 and a floor rear cross beam 212, the floor longitudinal beam includes a floor left longitudinal beam 221 and a floor right longitudinal beam 222, the floor side beam includes a floor left beam 231 and a floor right beam 232, and the floor panel 1 is welded to the floor beam frame 2. Specifically, the floor panel is welded to the floor front cross beam 211, the floor rear cross beam 212, the floor left longitudinal beam 221, the floor right longitudinal beam 222, the floor left beam 231 and the floor right beam 232, respectively, and the floor beam frame 2 and the welding of the floor panel 1 are existing automobile floor technologies.

[0062] In this application, Figure 1 The floor panel 1 has a bilaterally symmetrical structure. Figure 2 for Figure 1 Schematic diagram of the structure after flipping. Figure 2 The floor panel 1 area framed by the dotted line is the panel inside the beam. Figure 4 yes Figure 1 The local transverse section view, and the section plane passes through the center of the second external reinforcement rib, Figure 5 yes Figure 1 The longitudinal section of the part is shown, and the section plane passes through the center of the second outer reinforcement rib. Although the structures of the floor panel 1, the floor beam frame 2, etc. may be different according to different models, there is always a welding relationship between the floor panel 1 and other peripheral parts (such as the floor beam frame 2 and the front cabin, etc.). The floor panel 1 is divided into an inner beam area panel 11 and an outer beam area panel 12 by the floor cross beam and the floor longitudinal beam. The inner beam area panel 11 covers the floor cross beam and the floor longitudinal beam, that is, the inner beam area panel 11 is opposite to the floor cross beam and the floor longitudinal beam, and the outer beam area panel 12 avoids the floor cross beam and the floor longitudinal beam, that is, the outer beam area panel 12 is not opposite to the floor cross beam and the floor longitudinal beam.

[0063] like Figure 1 and Figure 2 As shown, the automobile floor panel provided by the embodiment of the present invention, that is, the automobile floor panel 1, is provided with external beam reinforcement ribs for reinforcing the panel 12 of the external beam area thereof, and internal beam reinforcement ribs for reinforcing the panel 11 of the internal beam area thereof;

[0064] The automobile floor panel is also provided with a reinforcing rib connection portion 16; the reinforcing rib connection portion 16 is a part of the welding panel area of ​​the automobile floor panel used for welding with other parts (i.e., parts other than the floor panel);

[0065] At least one of the beam external reinforcement ribs and the beam internal reinforcement ribs comprises a reinforcement rib lower concave portion 131 and a reinforcement rib upper convex portion 132; Figure 1 In the figure, only the rib concave portion 131 and the rib convex portion 132 of the second outer rib 13b of the beam outer rib, and the rib concave portion 141 and the rib convex portion 142 of the first inner rib 14a of the beam inner rib are marked. Figure 1 The markings of the first outer reinforcement 13a, the third outer reinforcement 13c, the fourth outer reinforcement 13d and the fifth outer reinforcement 13e of the external reinforcement of the beam, and the second inner reinforcement 14b, the third inner reinforcement 14c and the fourth inner reinforcement 14d of the internal reinforcement of the beam and the concave parts and convex parts of the reinforcement are omitted.

[0066] The reinforcing rib lower concave portion 131 is gradually concave downward in an arc shape from the outer periphery to the center, and the outer periphery extends to the reinforcing rib connecting portion 16;

[0067] The outer periphery of the rib upper protrusion 132 extends to the inner periphery of the rib lower concave portion 131 , and the rib upper protrusion 132 protrudes upward relative to the inner periphery of the rib lower concave portion 131 ;

[0068] The reinforcing rib upper protrusion 132 is located below the reinforcing rib connecting portion 16 .

[0069] Compared with the prior art, the automobile floor panel provided by the embodiment of the present invention has a reinforcing rib extending to the reinforcing rib connection portion 16. When assembling the automobile, the reinforcing rib connection portion 16 is welded to other parts (such as the floor beam frame 2, the front cabin, etc.). The reinforcing rib runs through the welding panel area where the floor panel 1 is welded to other parts in the horizontal, vertical or other directions. Therefore, the excitation force from the welding surface of the floor panel 1 and other parts can be effectively transmitted, thereby reducing the vibration of the floor panel 1.

[0070] The rib lower concave portion 131 is concave downward relative to the rib connecting portion 16, and the rib upper convex portion 132 is convex upward relative to the rib connecting portion 16, so that the rib has a higher rigidity by increasing the depth of the rib lower concave portion 131 relative to the rib connecting portion 16, thereby reducing the deformation of the floor panel 1 when subjected to external force, and the cross section of the rib is arched, which can quickly suppress vibration, thereby reducing the vibration of the floor panel 1;

[0071] The excitation force is transmitted from the floor beam frame 2 to the floor panel 1 through the welding surface between the floor panel 1 and the floor beam frame 2. The excitation force on the floor panel 1 is generally in the vertical direction. The concave part 131 of the reinforcing rib is gradually concave downward from the outer periphery to the center in an arc shape. There is an angle between the normal direction of the concave part 131 of the reinforcing rib and the excitation force, such as Figure 4 The middle excitation force F0 is decomposed into a force F1 along the normal direction of the concave part 131 under the reinforcing rib and a force F2 along the tangential direction of the concave part 131 under the reinforcing rib. F1 makes the panel vibrate. Since F1 is smaller than F0, the normal vibration of the concave part 131 under the reinforcing rib can be effectively reduced, and the vibration of the floor panel 1 can be reduced.

[0072] The rib lower concave portion 131 is concave downward relative to the inner circumference of the rib connecting portion 16, and the rib upper convex portion 132 convex upward relative to the inner circumference of the rib lower concave portion 131 is located below the rib connecting portion 16, so that the rib as a whole is lower than the welding panel area where the floor panel 1 is welded with other parts, and the area where the floor panel 1 is welded with other parts has a higher rigidity, thereby preventing the rib from being deformed by the operator stepping on it during the actual production process;

[0073] Through the above-mentioned multiple aspects, the vibration of the floor panel 1 is reduced, thereby achieving the effect of reducing the sound radiation of the floor panel, which not only improves the road noise performance of the whole vehicle, but also reduces the amount of damping material used in the vehicle body, thereby achieving weight reduction and cost reduction.

[0074] Specifically, one reinforcing rib lower concave portion corresponds to one or more reinforcing rib upper convex portions. Figure 1 Among them, the first outer reinforcing rib 13a has two reinforcing rib upper protrusions, the fourth outer reinforcing rib 13d has four reinforcing rib upper protrusions, and the other reinforcing ribs have only one reinforcing rib upper protrusion.

[0075] Specifically, Figure 4 and Figure 5 As shown, the depth of the arc surface where the bottom surface of the rib lower concave portion 131 is located relative to the rib connecting portion 16 (i.e., the arc surface height of the rib lower concave portion 131) H1≥12mm, and the rib lower concave portion 131 can be further deepened according to the size of the large surface of the floor panel 1. The rib lower concave portion 131 is recessed downward relative to the rib connecting portion 16, and the rib upper convex portion 132 is convex upward relative to the rib connecting portion 16, so that the depth H1 can be increased to more than 12mm, breaking through the existing limitation that the height of the rectangular rib does not exceed 8mm, so that the overall profile of the rib has higher rigidity, and the deformation of the floor panel 1 when subjected to external force is reduced.

[0076] In one embodiment, if Figure 4 As shown, the rib upper convex portion 132 includes a rib upper convex side portion 1321 and a rib inner top portion 1322;

[0077] The convex side portion 1321 of the reinforcing rib gradually bulges upward from the outer periphery to the center, and the outer periphery extends to the inner periphery of the concave portion 131 of the reinforcing rib;

[0078] The inner top portion 1322 of the reinforcing rib is gradually concave downward from the outer circumference to the center in an arc shape, and the outer circumference of the inner top portion 1322 of the reinforcing rib extends to the inner circumference of the convex side portion 1321 of the reinforcing rib.

[0079] There is an angle between the normal direction of the convex side portion 1321 of the reinforcing rib and the excitation force to reduce the normal vibration of the convex portion 132 on the reinforcing rib. There is an angle between the normal direction of the area outside the center point of the top portion 1322 of the reinforcing rib and the excitation force to reduce the normal vibration of the convex portion 132 on the reinforcing rib, thereby reducing the vibration of the floor panel 1 and improving the road noise performance.

[0080] Preferably, the convex side portion 1321 of the reinforcing rib is gradually curved upward from the outer circumference to the inner circumference, which is more conducive to reducing the vibration of the floor panel 1.

[0081] Specifically, Figure 4 and Figure 5 As shown, the depth H2 of the center point of the bottom surface of the inner top 1322 of the reinforcing rib convexly relative to the center point of the arc surface where the bottom surface of the lower concave portion 131 of the reinforcing rib is located is ≥6mm. This makes the cross section of the overall profile of the reinforcing rib present an inverse curvature bow shape, which better suppresses the vibration of the panel. Preferably, the width W1 of the inner top 1322 of the reinforcing rib in the horizontal direction is about 25mm.

[0082] Specifically, Figure 4 and Figure 5 In the embodiment, the width W2 of the concave portion 131 under the reinforcing rib is 108 mm, and the length W3 of the concave portion 131 under the reinforcing rib is 360 mm. W2 and W3 may be different according to different floor beam frames of different vehicle models.

[0086] Preferably, a first outer reinforcing rib 13 a is respectively provided on the left side of the left floor longitudinal beam 221 and the right side of the right floor longitudinal beam 222 .

[0087] By extending the first outer reinforcing rib 13a to the connecting portion of the first outer reinforcing rib, reinforcement and vibration suppression are achieved in the area of ​​the floor panel 1 that is located in front of the front floor cross beam 211 and on the left side of the left floor longitudinal beam 221, or reinforcement and vibration suppression are achieved in the area of ​​the floor panel 1 that is located in front of the front floor cross beam 211 and on the right side of the right floor longitudinal beam 222.
