Further, in one embodiment, the backplate 1 has a length of about 1.9m and a width of about 1.3 m. Therefore, the design of the large-area bottom guard plate 1 is beneficial to improving the bottom supporting prevention and stone impact resistance of the whole vehicle, and further the safety performance of a battery system and the vehicle is improved. Further, as shown in fig. 4, by the design of the protective flange 12 around the bottom guard plate 1, the problem that the battery box fixing point 15 is overloaded and the bottom guard plate body 11 is torn after water flow impacts the bottom guard plate 1 when the vehicle runs in wading can be effectively prevented, so that the impact resistance of the power battery bottom guard plate structure 100 is greatly improved.
Further, as shown in fig. 1, the first set of fixing points 2 may include a plurality of first fixing locations 21, and the plurality of first fixing locations 21 are spaced apart from each other at the peripheral edge of the backplate body 11. Like this, through a plurality of first fixed mounting position 21 at the peripheral edge interval distribution of end backplate body 11, can paste the peripheral edge of end backplate 1 in the vehicle bottom more firmly, reduce the gap of the peripheral edge of end backplate 1 and vehicle bottom, and then can reduce water and dust effectively and get into between backplate 1 and battery box 4 on the end, the security performance of reinforcing car. Simultaneously, every first fixed mounting position 21's atress is even relatively, avoids because of the atress that first fixed mounting position 21 overall arrangement problem leads to is unbalanced, and then leads to first fixed mounting position 21 to tear the scheduling problem. Further, each first fixed mounting position 21 may include: the battery case 4 is provided with a first mounting hole 22 and a first threaded fastener 23, and a blind rivet nut 24 is provided at a position corresponding to the first mounting hole 22. Specifically, the blind rivet nut 24 may be fixed to the battery case 4 by friction welding, an internal thread 25 is formed in the blind rivet nut 24, and the first threaded fastener 23 is fitted to the blind rivet nut 24 after passing through the first mounting hole 22, specifically, as shown in fig. 6, the first mounting hole 22 is coaxially arranged with the first mounting channel 26, the internal thread 25 may be formed on an inner circumferential surface of the first mounting channel 26, and the first threaded fastener 23 may be screwed with the blind rivet nut 24. Specifically, the first threaded fastener 23 may be a bolt, which may facilitate the assembly personnel to use a tool to install or remove the first threaded fastener 23. For example, in one embodiment, the first threaded fasteners 23 may be hex flange header alignment bolts, which simplifies the fitting work. Further, in the actual assembly process, a hole is formed in the position of the battery box body 4 corresponding to the first fixed mounting position 21, and according to the requirement of the sealing design of the battery box body 4, if the position needs to be sealed, a sealing type rivet nut 24 can be selected; if this position is an open area of the battery case 4 and sealing is not involved, the non-sealing type blind rivet nut 24 having a lower cost and a shorter height can be used. In the description of the present invention, "a plurality" means two or more.
Further, as shown in fig. 8, the second group of fixing points 3 includes a plurality of second fixing locations 31, and the plurality of second fixing locations 31 are disposed around the reinforcing recess 14 located in the middle of the bottom guard plate body 11, so that the plurality of second fixing locations 31 are disposed in the middle of the bottom guard plate 1, and the middle of the bottom guard plate 1 can be more firmly attached to the bottom of the vehicle, so as to improve the modal structure of the bottom guard plate 1 and prevent the middle of the bottom guard plate 1 from collapsing downward. Simultaneously, every second fixed mounting position 31's atress is even relatively, avoids because of the atress that second fixed mounting position 31 overall arrangement problem leads to is uneven, the second fixed mounting position 31 that leads to tears the scheduling problem. Further, each second fixed mounting position 31 may include: the second mounting hole 32 and the second threaded fastener 33 may be fixed with a threaded post 34 at a position on the battery case 4 corresponding to the second mounting hole 32, specifically, the threaded post 34 may be fixed on the battery case 4 by friction welding, and the threaded post 34 may be made of a metal material, for example, in an embodiment, the threaded post 34 may be made of an aluminum profile. The threaded post 34 is embedded with a threaded sleeve 35, and the second threaded fastener 33 is inserted through the second mounting hole 32 and then is fitted in the threaded sleeve 35. Specifically, the second mounting hole 32 is coaxially arranged with the second mounting passage 37, the threaded sleeve 35 is embedded in the second mounting passage 37, and the second threaded fastener 33 may be threadedly engaged with the threaded sleeve 35. Specifically, the second threaded fastener 33 may be a bolt, which may facilitate the assembly personnel to use a tool to install or remove the second threaded fastener 33. For example, in one embodiment, the second threaded fasteners 33 may be hex flange header alignment bolts, which simplifies the fitting work. Further, in the actual assembly process, the battery box body 4 is opened at the position corresponding to the second fixed mounting position 31, the prefabricated threaded column 34 is arranged in the hole, the upper part and the lower part of the threaded column are fully welded with the bottom plate of the box body to ensure welding sealing, the threaded sleeve 35 is embedded in the threaded column 34, and the bottom protection plate 1 is fixed with the bottom of the vehicle through the second threaded fastener 33. Further, in one embodiment, since the battery box 4 is a double-layer aluminum alloy profile, the second set of fixing points 3 are located at positions that are communicated with the battery pack (not shown in the figure), if the sealing fails, the whole pack may fail to be airtight and watertight, which may cause a safety accident. The second set of fastening points 3 is selected as a more reliable welding type threaded stud 34, since the height of the sealing type blind rivet nut 24 is too high, the operating height of the location where the second set of fastening points 3 is located is limited, and the pulling cannot be performed. In the description of the present invention, "a plurality" means two or more.
Further, as shown in fig. 5, the height at which the head of the second threaded fastener 33 protrudes downward with respect to the upper surface of the apron body 11 is smaller than the height at which the reinforcement recess 14 protrudes downward with respect to the upper surface of the apron body 11. Specifically, after the second threaded fastener 33 is screwed, the head of the second threaded fastener 33 is hidden in the space between the two reinforcing recesses 14 of the backplate 1, so that the head of the second threaded fastener 33 can be prevented from becoming the lowest point of the whole vehicle, the problem of tearing of the second group of fixing points 3 caused by the fact that the chassis scratches the second threaded fastener 33 of the backplate 1 is reduced, and the risk of sealing failure of the battery box 4 is further caused. Furthermore, the bottom protection plate 1 is of a single-layer thin plate structure, and the reinforced concave pits 14 designed on the surface can meet the requirement of strength impact resistance of the bottom protection plate structure 100 of the power battery pack, so that the function of effectively protecting the battery pack is realized.
Further, as shown in fig. 10, a threaded post welding avoiding groove 36 is formed at the peripheral edge of the second mounting hole 32, and the threaded post welding avoiding groove 36 is concentric with the second mounting hole 32 and is recessed downward relative to the upper surface of the bottom backplate body 11. Therefore, the sealing problem caused by grinding the surface of the welding seam is solved.
