Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The structural schematic diagram of the new energy automobile battery pack bracket is shown in fig. 1 and 2, the bracket is installed between one side of a battery pack protruding part 10 and a floor beam 12, the bracket is wholly dustpan-shaped and comprises a first horizontal surface 1, a vertical surface 2, a second horizontal surface 3, an inclined surface 4 and a first side surface 5 and a second side surface 6 which are sequentially adjacent, are symmetrical relative to the center line of the bracket and are perpendicular to and adjacent to the first horizontal surface 1, the vertical surface 2, the second horizontal surface 3 and the inclined surface 4. The first horizontal surface 1 is attached to and fixed with the upper surface of the battery pack protruding part 10; the vertical surface 2 is attached and fixed with one vertical side surface of the battery pack protruding part 10; the second horizontal plane 3 is positioned in a transition area between the battery pack protruding part 10 and the floor beam 12, one part of the second horizontal plane is attached to and fixed with the bottom flanging 11 of the battery pack protruding part 10, and the other part of the second horizontal plane is suspended; the inclined surface 4 is jointed and fixed with the floor beam 12.
In this embodiment, the bracket is used to connect the floor cross member 12, which has to be disconnected because the battery pack protruding portion 10 occupies space, to the battery pack protruding portion 10 into one integrated cross member. The battery pack projection 10 is shaped like a rectangular parallelepiped with three vertical sides and an upper surface exposed, and has a bottom flange 11 at its bottom. Therefore, in practice, two brackets are required to be respectively installed between the two opposite sides of the battery pack protruding portion 10 and the broken floor cross member 12.
In the present embodiment, the overall shape of the bracket is similar to a dustpan, and is mainly composed of a first horizontal surface 1, a vertical surface 2, a second horizontal surface 3, an inclined surface 4, and opposite first and second side surfaces 5 and 6. The first horizontal plane 1 is positioned at the tail part of the dustpan, and is attached and fixed with the upper surface of the battery pack protruding part 10 during installation; the vertical surface 2 is adjacent to the first horizontal surface 1 and is attached to and fixed to one vertical side of the protruding portion 10 of the battery pack. The horizontal and vertical directions in this embodiment are approximate terms, and do not refer to the exact horizontal and vertical directions, and the inclination angle should be designed on the principle that the inclination angle can be attached to the protruding portion 10 of the battery pack to the maximum extent; the second horizontal plane 3 is adjacent to the vertical plane 2, one part of the second horizontal plane is attached and fixed with the bottom flanging 11 of the battery pack protruding part 10 during installation, and the part close to the floor beam 12 is suspended, because the second horizontal plane 3 is just positioned in the transition area between the battery pack protruding part 10 and the floor beam 12, and the floor beam 12 in the area is an inclined plane; the inclined surface 4 is adjacent to the second horizontal surface 3, is positioned at the front end of the dustpan, and is attached and fixed together with the inclined surface of the floor cross member 12 during installation. The inclination of the inclined surface 4 corresponds to the inclination of the floor cross member 12.
In the embodiment, the two brackets are respectively arranged between the left side and the right side of the battery pack protruding part 10 and the disconnected floor beam 12, so that the disconnected floor beam 12 and the battery pack protruding part 10 are connected into an integral beam from left to right, the rigidity continuity of the beam is improved, the inherent modes of the floor and the battery pack are strengthened, and the structural noise caused by the modes is reduced. Experiments show that the mode of the protruding structure of the battery pack is improved from 71Hz to 80 Hz; the noise response of the whole vehicle road surface is reduced by 3.1dB at 71Hz, and other frequency points are also obviously reduced.
As an alternative embodiment, the connection mode of the first horizontal surface 1, the vertical surface 2 and the second horizontal surface 3 and the battery pack protruding part 10 and the connection mode of the inclined surface 4 and the floor beam 12 are the carbon dioxide protection welding mode.
The present embodiment shows the fixed connection of the bracket to the battery pack protruding part 10 and the floor beam 12, i.e. the carbon dioxide protection welding method is adopted. Carbon dioxide gas welding is a method of welding using carbon dioxide gas as a shielding gas. Is suitable for automatic welding and all-round welding. The wind can not be blown during welding, and the welding machine is suitable for indoor operation. The carbon dioxide protection welding has the advantages of low cost, simple operation, small deformation after welding and the like.
As an alternative embodiment, the vertical surface 2 and the second horizontal surface 3 are provided with ribs 7 at their transition.
In the present embodiment, in order to strengthen the stiffness of the abutment of the vertical surface 2 and the second horizontal surface 3, a rib 7 is provided at the transition between the vertical surface 2 and the second horizontal surface 3. The ribs 7 are manufactured in a stamping forming processing mode and are integrally formed with adjacent parts.
Preferably, the height of the ribs 7 is 5 mm.
As an alternative embodiment, the second horizontal surface 3 is provided with a first bolt mounting hole 8, and the inclined surface 4 is provided with a second bolt mounting hole 9.
In the present embodiment, in order to enhance the degree of firmness of the connection of the bracket with the battery pack protruding portion 10 and the floor cross member 12, bolt mounting holes, i.e., the first bolt mounting hole 8 and the second bolt mounting hole 9, are provided on the second horizontal surface 3 and the inclined surface 4 of the bracket, respectively. The second horizontal surface 3 of the bracket is fastened with the bottom flanging 11 of the battery pack protruding part 10 through the matching of a bolt and a nut, and the inclined surface 4 of the bracket is fastened with the floor beam 12.
As an alternative embodiment, the first side 5 and the second side 6 are provided with flanges.
In this embodiment, in order to increase the stiffness of the first 5 and second 6 side of the bracket, a flange is provided on both sides.
