Please combine fig. 1 and fig. 2 to show, this application first provides a bottom backplate structure, including battery tray 10, backplate support 20 and backplate 30, backplate support 20 includes blocking portion 21, and blocking portion 21 sets firmly in battery tray 10's bottom surface or side, and blocking portion 21 is located battery tray 10's grafting mouth 11 and is close to one side on ground, and shelter from grafting mouth 11 along vertical direction, and backplate 30 sets firmly in backplate support 20, and offsets with blocking portion 21 along vertical direction.

The utility model provides a bottom backplate structure is fixed in battery tray 10 through will shelter from backplate support 20 of interface 11 along vertical direction, is fixed in this backplate support 20 with backplate 30 to make the clearance between backplate 30 and the battery tray 10 can be stopped to the stop part 21 of backplate support 20, avoid grit, the earth that splashes to strike interface 11 through the clearance, increased driving safety.

Secondly, the guard plate 30 abuts against the blocking portion 21 in the vertical direction; it will be appreciated that if there is a gap between the guard plate 30 and the blocking portion 21 in the vertical direction, sand and soil may enter the upper side of the guard plate 30 through the gap, and when the vehicle jolts, the sand and soil on the upper side of the guard plate 30 may also impact the insertion port 11, and the guard plate 30 may be abutted against the blocking portion 21 in the vertical direction, so that the occurrence of the above situation can be avoided, and the driving safety of the vehicle is further increased.

Referring to fig. 2, in some embodiments, a shield bracket 20 is fixed to a side of the battery tray 10; fixing the apron bracket 20 to the bottom of the battery tray 10 reduces the ground clearance between the vehicle and the ground, resulting in reduced vehicle passability.

The guard plate support 20 may be fixed to the battery tray 10 by a common fixing manner such as bolting, welding, clamping, etc., which is not further limited herein.

Referring to fig. 2, in some embodiments, the shield support 20 is integrally formed with the battery tray 10; so as to ensure that gaps are not caused by installation errors or other reasons between the guard plate support 20 and the battery tray 10, and further increase the protection effect of the guard plate support 20 on the plug-in interface 11; in addition, through the integrated into one piece backplate support 20 and battery tray 10, reduced the step of fixed backplate support 20 and battery tray 10, reduced the whole installation step and the installation degree of difficulty of end backplate structure.

Referring to fig. 3 and 4, in some embodiments, the blocking portion 21 includes a bending section 211 and a horizontal section 212 connected to each other, the bending section 211 is connected to the battery tray 10, the width of the bending section 211 is 5 mm-10 mm, and the width of the horizontal section 212 is 5 mm-10 mm.

Wherein, the width of the bending section 211 is 5 mm-10 mm so as to be convenient for processing and forming; the width of the horizontal segment 212 is 5mm to 10mm, that is, the width of the portion of the blocking portion 21 abutting against the guard plate 30 is 5mm to 10mm, it is understood that if the width is too small, the splashed mud water may infiltrate from the abutting position, the protection effect on the insertion port 11 is poor, and if the width is too large, the production cost of the bottom guard plate structure increases due to the increase of the material consumption; the width of the horizontal section 212 is controlled to be 5-10 mm, so that the production cost of the bottom guard plate structure can be reduced as much as possible on the premise of avoiding muddy water infiltration and guaranteeing the protection effect.

Referring to fig. 2 and 4, in some embodiments, the guard 30 is located on a side of the guard support 20 near the ground; on the one hand, the mounting of the guard plate 30 by workers can be facilitated, on the other hand, under the condition that the guard plate support 20 is identical in position, the available space on the upper side of the guard plate 30 is larger when the guard plate 30 is mounted on the lower side of the guard plate support 20, and the arrangement of other components of the chassis is facilitated.

Referring to fig. 2 and 4, in some embodiments, the guard support 20 further includes at least two mounting portions 22, the mounting portions 22 are fixed to a side of the blocking portion 21 away from the battery tray 10, and the guard 30 is fixed to the mounting portions 22.

Compared with the method of increasing the width of the blocking part 21 and fixing the guard plate 30 directly to the blocking part 21, the installation part 22 can meet the installation requirement of the guard plate 30, and meanwhile, the material consumption is relatively low, so that the production cost of the bottom guard plate structure can be effectively reduced.

At least two mounting portions 22 such that a section of the sheathing plate 30 adjacent to the battery tray 10 has at least two fixing points to secure stable mounting of the sheathing plate 30; specifically, the number of the mounting portions 22 is set according to the structural strength requirement, and the present application is not further limited herein.

Referring to fig. 2 and fig. 4, in some embodiments, a blind rivet nut 221 is fixedly disposed on an end surface of the mounting portion 22, which is far away from the ground, and the guard plate 30 is fixedly connected to the blind rivet nut 221 through bolts.

Of course, the mounting portion 22 and the guard plate 30 may be connected by welding, fastening, or other common fixing methods, which are not illustrated herein.

In some embodiments, the bottom surface of the guard 30 is flush with the bottom surface of the battery tray 10; under the condition that the thickness of the guard plate 30 is fixed, when the ground of the guard plate 30 is level with the bottom surface of the battery tray 10, the available space on the upper side of the guard plate 30 is maximized on the premise that the ground clearance of the vehicle is not reduced, so that other components of the chassis are conveniently arranged.

Referring to fig. 2, in some embodiments, the blocking portion 21 is flush with the side of the battery tray 10 along its length.

It will be appreciated that if the blocking portion 21 corresponds to only a portion of the insertion port 11, there will be a gap between the shield plate 30 and the remaining battery tray 10 at other positions, and that splashed silt and crushed stone may enter the space above the shield plate 30 from this portion of gap and strike the insertion port 11 when the vehicle is driving over bumps.

By providing the blocking portion 21 flush with the side surface of the battery tray 10 in the longitudinal direction thereof, the occurrence of the above-described situation can be prevented, and the running safety of the vehicle can be further increased.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
