[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is combined Figures 1-5 Describes the vehicle body according to an embodiment of the present utility model.

[0028] The vehicle body of this embodiment includes a battery compartment 1, a rear fender 2, and a rear bumper bracket 3. The battery compartment 1 includes a rear side plate 11 and a flange 12. The flange 12 is disposed on the top of the rear side plate 11 and extends rearward relative to the rear side plate 11. The front part of the rear fender 2 is located below the flange 12 and is connected to the flange 12 by a first fastener. The rear part of the rear fender 2 is located above the rear wheel. At least a portion of the rear bumper bracket 3 is disposed on the rear side of the rear side plate 11 and the lower side of the flange 12. The lowest point of the rear bumper bracket 3 is lower than the lowest point of the rear side plate 11.

[0029] According to the vehicle body of this utility model embodiment, by setting a portion of the rear mudguard 2 located below and connected to the folded edge 12, when the mud and water brought out by the rear wheel rotation flows forward along the rear mudguard 2, it is blocked by the rear mudguard 2 and the folded edge 12 and flows to the top of the battery compartment 1, thereby effectively preventing mud and water from entering the battery compartment 1 from the top. By setting at least a portion of the rear bumper bracket 3 on the rear side of the rear side plate 11 and the lower side of the folded edge 12, and extending downward to the lower side of the rear side plate 11, the mud and water brought out by the rear wheel rotation can be shielded by the rear bumper bracket 3 to avoid direct impact on the rear side plate 11, and effectively prevent mud and water from flowing to the bottom of the battery compartment 1, thereby more effectively preventing mud and water from entering the battery compartment 1 from the rear and bottom, thus ensuring good waterproof sealing of the battery in the battery compartment 1, and high battery life and safety.

[0030] It should be noted that the battery compartment 1 is made of plastic material such as PP, while the rear fender 2 and the rear fender bracket 3 are both metal parts. The main structure of the rear fender 2 is the same as that of the rear fender on electric vehicles in related technologies, and will not be described again here. The rear fender bracket 3 can be connected to the rear side panel 11 of the battery compartment 1, or it can be connected to the bottom plate 14 or other side panels of the battery compartment 1.

[0031] In some embodiments, the battery compartment 1 further includes a baffle 13 connected to the rear side of the rear side plate 11, the baffle 13 and the rear side plate 11 defining a downward-facing clearance groove 15, and the top of the rear bumper bracket 3 is disposed within the clearance groove 15.

[0032] By concealing the top of the rear bumper bracket 3 within the clearance groove 15, when mud and water impact the area of ​​the rear side panel 11 located above the rear bumper bracket 3 from rear to front, they can flow directly downwards to the outer surface of the rear bumper bracket 3 under the obstruction of the baffle 13, without entering the gap between the rear bumper bracket 3 and the rear side panel 11. This effectively prevents mud and water from accumulating in the gap and corroding the rear bumper bracket 3 and / or increasing the probability of mud and water entering the battery compartment 1.

[0033] For example, such as Figure 1 and Figure 2 As shown, the rear panel 11 of the battery compartment 1 is a Z-shaped panel, which includes an upper panel, a middle panel and a lower panel. The upper panel and the lower panel are both vertical panels, with the former located behind the latter. The middle panel is a horizontal panel. The upper end of the baffle 13 is connected to the lower end of the upper panel. The baffle 13, the middle panel and the lower panel surround each other to form a clearance groove 15. The clearance groove 15 extends to the left and right sides of the battery compartment 1 in the left and right directions.

[0034] In some embodiments, the rear bumper bracket 3 is a metal part, and the vehicle body also includes a rear mudguard 4, which is a non-metallic part and is disposed on the rear side of the rear bumper bracket 3. The lowest point of the rear mudguard 4 is lower than the lowest point of the rear bumper bracket 3.

[0035] The rear mudguard 4 replaces the rear bumper bracket 3 to block mud and water, thereby effectively preventing the rear bumper bracket 3 from being corroded by mud and water adhering for a long time, which would reduce its service life. Furthermore, by setting the lowest point of the rear mudguard 4 to be lower than the lowest point of the rear bumper bracket 3, the rear mudguard 4 can cover the lowest point of the rear bumper bracket 3, effectively preventing mud and water from flowing down the rear mudguard 4 and flowing under the rear bumper bracket 3, thus increasing the risk of entering the battery compartment 1.

[0036] For example, the rear mudguard 4 is a rubber pad, the width of the rear mudguard 4 is greater than or equal to the width of the rear fender bracket 3, and the upper edge of the rear mudguard 4 is lower than the lower edge of the baffle 13.

[0037] In some embodiments, the rear mudguard 4 is provided with a plurality of grooves 41 arranged at intervals along the left and right direction of the battery compartment 1. The grooves 41 extend along the thickness direction of the rear mudguard 4 and penetrate the rear mudguard 4. The grooves 41 are provided with openings on the bottom surface of the rear mudguard 4, and the width of the grooves 41 gradually increases from top to bottom.

[0038] This causes the total width of the rear mudguard 4 at the location of the groove 41 to gradually decrease from top to bottom. As a result, when mud and water splashed onto the rear mudguard 4 flow to the part between any two adjacent grooves 41, they can be released more quickly, effectively preventing mud and water from lingering on the rear mudguard 4 and causing mud accumulation that affects the appearance.

[0039] For example, such as Figure 5 As shown, the groove 41 is a triangular groove, and multiple grooves 41 are arranged at equal intervals along the left and right directions of the rear mudguard 4, thereby forming a toothed edge at the bottom of the rear mudguard 4.

[0040] In some embodiments, the battery compartment 1 further includes a base plate 14, and the rear bumper bracket 3 includes a connected rear connecting plate 31 and a bottom connecting plate 32. The bottom connecting plate 32 is connected to the base plate 14 by a second fastener. The rear connecting plate 31 is located on the rear side of the rear side plate 11, and the rear mudguard 4 is disposed on the rear side of the rear connecting plate 31.

[0041] Compared to directly connecting the rear bumper bracket 3 to the rear side panel 11, this embodiment eliminates the need for mounting holes on the rear side panel 11 for connecting to the rear bumper bracket 3. This effectively reduces the risk of mud and water entering the battery compartment 1 through these mounting holes, resulting in a higher level of sealing and waterproofing for the battery compartment 1. Furthermore, this design allows the rear connecting plate 31 to cover a larger and wider area of ​​the rear side panel 11, providing better mud protection for the rear side panel 11.

[0042] For example, such as Figure 1 , Figure 3 and Figure 4As shown, two second nuts are welded on the bottom connecting plate 32, which are spaced apart in the left and right direction. The bottom plate 14 of the battery compartment 1 is provided with an assembly hole. When assembling the rear support bracket 3, the top of the rear connecting plate 31 is first inserted into the clearance groove 15, and then the second fastener passes through the assembly hole from top to bottom and is threadedly connected to the second nut.

[0043] In some embodiments, the rear connecting plate 31 includes a first folding plate 311, a second folding plate 312, and a third folding plate 313 connected sequentially from top to bottom. The second folding plate 312 is bent backward relative to the first folding plate 311, and the third folding plate 313 is bent downward relative to the second folding plate 312. At least one of the second folding plate 312 and the third folding plate 313 is connected to the rear mudguard 4.

[0044] At this time, the second folding plate 312 and the third folding plate 313 are spaced apart from the rear side plate 11 in the front-rear direction. Thus, each of the second folding plate 312 and the third folding plate 313 can form an assembly space with the rear side plate 11, which facilitates the connection of at least one of the second folding plate 312 and the third folding plate 313 with the rear mudguard 4, and the assembly efficiency of the vehicle body is higher.

[0045] For example, such as Figure 2 and Figure 4 As shown, the first folding plate 311 and the third folding plate 313 are both vertical plates. The thickness of the first folding plate 311 is less than the width of the clearance groove 15. The second folding plate 312 is an inclined plate at an angle to the vertical direction. After the rear bumper bracket 3 is installed in the battery compartment 1, the upper edge of the first folding plate 311 abuts against the top wall of the clearance groove 15.

[0046] In some embodiments, the second folding plate 312 is snapped into the rear mudguard 4. And / or, the third folding plate 313 is connected to the rear mudguard 4 by a third fastener. This makes the connection between the rear mudguard 4 and the rear connecting plate 31 convenient and reliable, the rear mudguard 4 is not easy to fall off, and has a long service life.

[0047] For example, such as Figure 4 and Figure 5 As shown, the front side of the top of the rear mudguard 4 has three locking protrusions 42 spaced apart in the left-right direction. The second folding plate 312 has three corresponding locking holes 3121. The locking protrusions 42 are inserted into the locking holes 3121 by deformation and spring back to abut against the inner side of the second folding plate 312. Two third nuts are welded to the third folding plate 313 spaced apart in the left-right direction. The rear mudguard 4 has two corresponding mounting holes. The third fastener passes through the mounting holes and is threadedly connected to the third nuts to complete the assembly of the mudguard 4.

[0048] In some embodiments, the rear bumper bracket 3 further includes a left limiting plate 33 and a right limiting plate 34. The left limiting plate 33 and the right limiting plate 34 are respectively connected to the two opposite ends of the bottom connecting plate 32 in the left-right direction of the battery compartment 1. The left limiting plate 33, the right limiting plate 34 and the bottom connecting plate 32 surround to form a limiting groove, and the battery compartment 1 is disposed in the limiting groove.

[0049] Therefore, when assembling the rear bumper bracket 3, the battery compartment 1 is inserted downward into the limiting groove to limit the battery compartment 1 and the rear bumper bracket 3 in the left and right directions, and the connection efficiency between the low connecting plate of the rear bumper bracket 3 and the bottom plate 14 of the battery compartment 1 is higher.

[0050] For example, such as Figure 4 As shown, the left limiting plate 33 and the right limiting plate 34 are arranged in a mirror symmetrical manner and are both connected to the bottom connecting plate 32. There are two sets of left limiting plates 33 and right limiting plates 34, which are arranged at intervals along the front-back direction.

[0051] In some embodiments, the vehicle body further includes a mounting bracket 5, which is disposed on the rear mudguard 2 away from the folded edge 12. The mounting bracket 5 is provided with a first nut, the folded edge 12 is provided with a first mounting hole 121, the rear mudguard 2 is provided with a second mounting hole, and a first fastener passes through the first mounting hole 121 and the second mounting hole and is threadedly connected to the first nut.

[0052] When the rear mudguard 2 is made of plastic, by setting the mounting bracket 5, the front part of the rear mudguard 2 can be clamped and fixed between the mounting bracket 5 and the folded edge 12. At the same time, the contact area between the front part of the rear mudguard 2 and the folded edge 12 and the mounting bracket 5 is increased. The front part of the rear mudguard 2 is subjected to less force from the folded edge 12 and the mounting bracket 5, and is therefore less prone to deformation and damage, resulting in a longer service life for the rear mudguard 2.

[0053] For example, such as Figure 1 and Figure 3 As shown, two first nuts are welded on the mounting bracket 5, which are spaced apart in the left-right direction. There are two corresponding first mounting holes 121, which are waist-shaped holes with the length direction consistent with the front-back direction. The first fastener is a bolt, which passes through the first mounting hole 121 from top to bottom and is threadedly connected to the first nut.
