[0028] See also Figure 1-5The utility model provides a technical solution: a motor system with a rear suspension mounting bracket, including a motor rear suspension mounting bracket body 1, a motor suspension pad 5 and a motor assembly 6. A mounting base plate 2 is provided on the motor rear suspension mounting bracket body 1. The mounting base plate 2 adopts a shearing process, and the bottom of the mounting base plate 2 is an arc-shaped structure. This structure enables the mounting base plate 2 to be sheared into a desired shape. The mounting base plate 2 is a plate-like structure, and the overall strength is guaranteed. At the same time, there are few scraps cut off. The arc-shaped structure at the bottom of the mounting base plate 2 is tightly snap-fitted with the outer shell of the motor assembly 6. This structure allows the mounting base plate 2 to be placed on the outer shell of the motor assembly 6 through the bottom arc-shaped structure, so that the mounting base plate 2 can be reliably positioned relative to the fixation of the motor assembly 6, so that it can be subsequently fastened by bolts. The hole 201 is used to fix the mounting base plate 2 and the motor assembly 6, and one side of the mounting base plate 2 is connected with a right suspension mounting plate 3 and a left suspension mounting plate 4 of a symmetrical structure. The right suspension mounting plate 3 and the left suspension mounting plate 4 are both made into an L-shaped structure by shearing and bending processes, and both sides of the right suspension mounting plate 3 and the left suspension mounting plate 4 are vertically arranged relative to the mounting base plate 2. This structure enables the right suspension mounting plate 3 and the left suspension mounting plate 4 to be made into an L-shaped structure by bending, so that the right suspension mounting plate 3 and the left suspension mounting plate 4 have reinforcing ribs, and at the same time increases the welding surface of the right suspension mounting plate 3 and the left suspension mounting plate 4 with the mounting base plate 2, thereby ensuring the structural strength of the motor rear suspension mounting bracket body 1, and a fastening hole 201 is opened on the mounting base plate 2, and the fastening hole 201 has three The fastening holes 201 are distributed in an isosceles triangle. This structure allows the mounting base plate 2 and the motor assembly 6 to be fixed by bolts passing through the fastening holes 201 to ensure the connection strength. The fastening holes 201 are distributed in an isosceles triangle to ensure that the motor rear suspension mounting bracket body 1 is evenly stressed. The right suspension mounting plate 3 and the left suspension mounting plate 4 are between the fastening holes 201 on both sides of the mounting base plate 2. This structure allows the mounting base plate 2 and the motor assembly 6 to be fixed unimpeded. The L-shaped bottom folded edges of the right suspension mounting plate 3 and the left suspension mounting plate 4 face outward. This structure allows the motor suspension pad 5 fixed between the right suspension mounting plate 3 and the left suspension mounting plate 4 to be firmly clamped. The right suspension mounting plate 3 and the left suspension mounting plate 4 are fixed by the L-shaped bottom folded edges. The row structure is strengthened, and there is enough installation space when the bolt passes through the fastening hole 201. The height of one end of the opposite side of the right suspension mounting plate 3 and the left suspension mounting plate 4 close to the mounting base plate 2 is greater than the height of the other end. This structure sets a triangular structure on the side where the right suspension mounting plate 3 and the left suspension mounting plate 4 are fixed to the mounting base plate 2, increases the welding surface of the right suspension mounting plate 3 and the left suspension mounting plate 4 and the mounting base plate 2, and improves the overall structural strength of the right suspension mounting plate 3 and the left suspension mounting plate 4. At the same time, the weight of the right suspension mounting plate 3 and the left suspension mounting plate 4 is reduced, and the fastening hole 201 is matched with the outer shell part of the motor assembly 6. The right suspension mounting plate 3 and the left suspension mounting plate 4 are respectively provided with a right connecting hole 301 and a left connecting hole 401.The right connecting hole 301 and the left connecting hole 401 are located at one end of the right suspension mounting plate 3 and the left suspension mounting plate 4 away from the mounting base plate 2. This structure allows the motor suspension pad 5 to be fixed to the end positions of the right suspension mounting plate 3 and the left suspension mounting plate 4 through the right connecting hole 301 and the left connecting hole 401, and the motor suspension pad 5 is clamped and installed between the right suspension mounting plate 3 and the left suspension mounting plate 4. The right connecting hole 301 and the left connecting hole 401 are located in corresponding positions, and the motor suspension pad 5 is fastened with bolts running through the right connecting hole 301 and the left connecting hole 401. This structure can achieve a stable positioning of the motor suspension pad 5. When the motor assembly 6 is installed to When installing the motor assembly 6 on the vehicle body, first fix the motor suspension pad 5 to the vehicle body, and then install the motor assembly 6 fixed with the motor rear suspension mounting bracket body 1 through the assembly of the motor rear suspension mounting bracket body 1 and the motor suspension pad 5. The assembly method is fast and convenient, and avoids the risk of damage caused by long-term suspension during installation of the motor assembly 6. By welding and assembling the three sheet metal parts of the bottom plate 2, the right suspension mounting plate 3 and the left suspension mounting plate 4, the generation of welds can be reduced. Only a general bending mold and a welding fixture are used to provide a structural strength that meets the design requirements. At the same time, the production mold structure is simple, and the comprehensive production cost is greatly reduced compared with the original.
