The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Referring to Fig. 1-5, a kind of backplate that is conducive to improve engine in front of rear wheel mid-engine chassis heat management performance, it comprises main body backplate part 1, main body backplate part top is provided with reinforced rib part 2, mounting portion 3, grate opening part 4 and upwarp water diversion part 5, main body backplate part is whole straight, upwarp and between water diversion part and grid opening portion, be provided with one section of straight transitions plate 10, the main body backplate left and right sides forms two suspension frame structure slot to make way 7-1 that dodge suspension frame structure, left and right slot to make way is respectively offered slot to make way grate opening 7-2 over against air flow line, described mounting portion 3 comprises positioning and mounting structure 3-1, before be connected and fixed structure 3-2 and after be connected and fixed structure 3-3, positioning and mounting structure 3-1 is positioned at the backplate left and right sides, on it, be provided with the mounting hole being connected with longitudinal floor beam, between the positioning and mounting structure of left and right, in order to dodge suspension frame structure, form respectively two suspension frame structures breach 6 of stepping down, be connected and fixed structure 3-2 and be positioned at main body backplate part 1 front end, on it, be provided with the mounting hole being connected with backplate under refrigerating module, after be connected and fixed on structure 3-3 and be provided with and the mounting hole of protecting oil pan tray support to be connected.
Preferably; be positioned at described main body backplate and partly go up, one one of side reduction forms an anti-oil pan tray heat protection breach 8 near oil pan tray to upwarp water diversion part one end, and its breach profile is similar to oil pan tray outward flange; depart from the about 10mm of oil pan tray, avoid forming heat protection and the heat radiation of reduction oil pan tray.
Referring to Fig. 1 and Fig. 2, chassis heat management backplate normally adopts ABS material to make, by main body backplate part 1, reinforced rib part 2, mounting portion 3, grate opening part 4, upwarp water diversion part 5 five parts and form.
Referring to Fig. 1 and Fig. 3, main body backplate part 1 area is larger, and whole maintenance is straight, can not convex, the flow direction engine body that above backplate, air-flow can be level and smooth like this, reduces air-flow droop loss, also can guarantee below backplate that cold airflow is close to chassis simultaneously, can be away from car body.Two reinforced rib parts 2 are set in main body backplate part 1, have guaranteed backplate intensity, rigidity requirement, Fig. 3 can find out, reinforced rib concaves, and has avoided backplate lower end cold fluid to move downward away from car body.
Referring to Fig. 1, the main body backplate left and right sides forms two suspension frame structure slot to make way 7-1 in order to dodge suspension frame structure, it is slot to make way grate opening 7-2 that left and right slot to make way is respectively offered two grid mouths over against air flow line, be convenient to cold airflow and enter, avoid local evagination part over against cold airflow can not enter thermal source district.
Referring to Fig. 1, grid opening portion 4, guaranteeing to open hole as much as possible under its intensity prerequisite, has guaranteed that cold airflow as much as possible enters body thermal source district, reaches maximum cooling-down effect like this.Grid opening portion 4 and upwarp 5 of water diversion parts and have to seamlessly transit a region, can guarantee the transition that air-flow is mild, reduces air-flow differential loss.Upwarping 5 of water diversion parts is that the flow direction of wind is accurately guided, and makes it enter high-temperature component region, so upwarp water diversion part 5 guiding angles, needs suitably.Near anti-oil pan tray heat protection breach 8 of formation of oil pan tray one side reduction, its breach profile is similar to oil pan tray outward flange, departs from the about 10mm of oil pan tray, avoids forming heat protection and the heat radiation of reduction oil pan tray.
Referring to Fig. 1 and 2, can find out, mounting portion 3 be divided into positioning and mounting structure 3-1, front be connected and fixed structure 3-2, after be connected and fixed structure 3-3, positioning and mounting structure 3-1 is mainly positioned at the backplate left and right sides, on it, be provided with the mounting hole being connected with longitudinal floor beam, between the positioning and mounting structure of left and right, in order to dodge suspension frame structure, form respectively two suspension frame structures breach 6 of stepping down, be connected and fixed structure 3-2 and be positioned at main body backplate part 1 front end, on it, be provided with the mounting hole being connected with backplate under refrigerating module; After be connected and fixed structure 3-3 and be the little adapter plate in three of 4 rear ends of grate opening part, on it, be provided with and the mounting hole of protecting oil pan tray support to be connected.Backplate reaches stable installation all around like this, can arbitrarily not rock.
Referring to Fig. 4; during installation; backplate need to be snapped into backplate outside under front-end cooling module; first aim at backplate positioning and mounting structure 3-1 and longitudinal floor beam 9 the corresponding mounting hole; location is installed, then by being connected and fixed structure 3-2 before backplate, is connected with backplate under refrigerating module, finally by being connected and fixed structure 3-3 after backplate, be connected with protection oil pan tray support; during installation, rock not too bigly, avoid the water diversion part that upwarps of backplate to encounter body miscellaneous part and cause damage.
Referring to Fig. 4 and Fig. 5, can find out, after installation, between chassis and backplate, form a more smooth-going cavity air channel, guaranteed that fan air-out all dispels the heat to engine block by air channel, the cold airflow (shown in Fig. 5 arrow) being simultaneously positioned at below backplate can enter main flow air channel end by grate opening part 4 smoothly, by water diversion part 5 orientations by the air-flow high-temperature area that leads.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of the claims in the present invention and equivalent technologies thereof, the intent of the present invention also comprises these changes and is out of shape interior.
