Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As shown in Figures 1 to 5, the power battery box, including babinet and case lid, babinet and case lid are cooperatively formed for arranging
The cavity of battery modules is installed.
Babinet includes the bottom of box 2 and the frame 1 that is located on the bottom of box 2, and the bottom of box 2 and frame 1 are aluminium alloy
The profile plate of profile plate, frame 1 is welded on the profile plate of the bottom of box.
The bottom of box 2 includes one group of profile plate being arranged side by side, and one group of profile plate welding is connected；Its section is designed, fully
Meeting the front and back dimensional stability of welding, and hit to ground stone, scrape, collide with etc. has enough protection intensity, and stress is made to become
Shape will not occur to battery.
Frame 1 uses proximate matter and floor welded, the proximate matter, section design to fully consider vibration, collision, extruding etc.
The requirement of machinery abuse.
One end of frame 1 is equipped with panel, and panel is equipped with plug-in unit mounting hole, is equipped with and adds between panel and the profile plate of frame
Strengthening tendons, to keep the continuous of frame intensity and toughness.
The opposite both sides of frame 1 are equipped with hoisting bracket 3, and the positioning being connected to each other with vehicle is equipped on hoisting bracket 3
Structure；Preferably, location structure is the positioning centrum 4 being located on hoisting bracket, convenient for being carried out during being installed to vehicle
Positioning.
The weld seam of base board sections welding is vertical with two rows of hoisting brackets.The bottom of box is equipped with installation support plate 5, and is pacifying
It fills support plate 5 and is equipped with one group of module mounting bracket 6；Mounting bracket is bending plate, and the bending part of bending plate is arc-shaped transition,
Including two support plates being oppositely arranged and the top plate being located between two support plates, the bottom of support plate is equipped with in-flanges, ensures to fix
Intensity, top plate are arc wave-shape board, are equipped with location and installation column on two support plates on top plate, are convenient for module location and installation, peace
Dress supporting structure is ingenious in design, and structural strength is big；And has the function of bumper and absorbing shock, ensure the reliability of positioning of module.
