The specific embodiment
In order better to understand the utility model, preferred embodiment is described in further detail to the utility model below in conjunction with accompanying drawing.
Extremely shown in Figure 5 as Fig. 1, a kind of vehicle power cell sealing structure, comprise automotive floor panel 1, be fixed in the mounting rail 2 of described automotive floor panel bottom surface 1, the battery tray 3 and the sealing band 4 of fixed pedestal electrokinetic cell, the week of described battery tray 3 is along having installation portion 31, described battery tray 3 is captiveed joint with described mounting rail 2 by its installation portion 31, described installation portion 31 is provided with seal groove 311, around setting, described sealing band 4 is arranged in the described seal groove 311 and has certain amount of compression described seal groove 311 along described installation portion 31.
Described installation portion 31 is provided with one deck seal groove 311 at least, all is provided with sealing band 4 in every layer of seal groove 311.The quantity that increases seal groove and sealing band can improve sealing effectiveness.
Extremely shown in Figure 5 as Fig. 1, described mounting rail 2 is fixed in the bottom surface of described automotive floor panel 1 by welding manner, described mounting rail 2 is captiveed joint with the installation portion 31 of described battery tray 3 by bolt connecting mode, installation portion 31 on the described battery tray 3 is provided with bolt hole 312, and described bolt hole 312 is arranged at the outside of described seal groove 311.Like this, even there is a small amount of water inlet at the bolted connection place, also can guarantee to form a failure-free seal cavity with inner region at described sealing band 4.
Extremely shown in Figure 5 as Fig. 1, consider that electrokinetic cell needs repairing, maintains and changes, described mounting rail 2 bottoms are provided with the bolt hole 21 that passes for bolt, upper base surface bolt hole place is welded with nut 22, and the position of described nut 22 is corresponding with the bolt hole 312 on the described battery tray installation portion 3.In the present embodiment, earlier nut 22 is welded to bolt hole 21 places of described mounting rail 2 upper base surface, mounting rail 2 is welded on the bottom surface of described automotive floor panel 1, described battery tray 3 cooperates with nut 21 on the described mounting rail 2 by bolt 5 and is fixed on the described mounting rail 2 again.When installing or pulling down electrokinetic cell, only need tighten or pull down bolt 5 and get final product, make things convenient for maintenance, maintenance and the replacing of electrokinetic cell.
As shown in Figure 6, the rectangular frame of described mounting rail for being welded to form by four sections straight beams.In order to improve the intensity of mounting rail, temperature distortion when preventing the mounting rail welding simultaneously adopts the spot welding mode to weld described four sections straight beams.For reducing the gap between described each section straight beam, at inboard sheet metal 23 each section of the overlap joint straight beams of mounting rail by arc.In order to ensure sealing property, in the position of weld of described curved metal thin plate 23 and each section straight beam and the position of weld on mounting rail and floor all smear sealant and seal.
