Use the service life.
Reinforcing plate is formed on the outside of the mounting plate, described reinforcing plate one end takes shape on mounting plate, and the other end is to pair
Vehicle frame direction, which tilts, to be extended and takes shape on subframe, and the effect of reinforcing plate is to improve the intensity and rigidity of mounting plate, in turn
Improve the performance of entire mounting bracket.
The subframe and mounting bracket are Al-alloy parts, can not only mitigate the weight of entire assembly, increase electronic vapour
The course continuation mileage of vehicle, and convenient for mounting plate to be designed to the structure of variable cross-section thickness, be also convenient for designing on the outside of mounting plate and reinforce
Plate.
For improve motor installation stability, the subframe include front-axle beam and front-axle beam be oppositely arranged the back rest, be connected to
Zuo Liang between aforementioned front-axle beam and the back rest and You Liang, the front-axle beam, the back rest, Zuo Liang and You Liang enclose the sky of a receiving motor
Chamber；
There are three the mounting brackets, and two of which mounting bracket is spaced apart and takes shape in front-axle beam by casting integrated
On, another mounting bracket is welded on the back rest.Three mounting brackets are arranged in triangle, make motor is firm to be installed on subframe
On.
The line of three mounting brackets is in equilateral triangle, further improves the stability of motor installation.
Compared with prior art, the advantages of the utility model：The utility model is by by least one motor mounting rack
It is integrally formed by low pressure casting with subframe, relative to the conventional motors mounting support structure of metal plate welding, the utility model
Welding sequence is omitted, avoids the assembly precision between welding deformation influence motor and mounting bracket, also avoids motor and shake
The dynamic weld cracking risk caused between mounting bracket and subframe, makes mounting bracket be connected firmly with subframe, and then make electricity
Machine is firm to be installed on subframe.The utility model takes shape in mounting bracket is casting integrated on subframe compared to weldering simultaneously
The mode connect reduces the weight of entire subframe, complete vehicle weight is made to reduce, and improves the continual mileage and vehicle of electric vehicle
Performance.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in figures 1-4, the motor mounting rack of the automobile of this preferred embodiment includes being set on subframe 1 to be used for
Install motor three mounting brackets 2, subframe 1 include front-axle beam 11 and front-axle beam 11 be oppositely arranged the back rest 12, be connected to it is aforementioned
Left beam 13 between front-axle beam 11 and the back rest 12 and right beam 14, front-axle beam 11, the back rest 12, left beam 13 and right beam 14 enclose receiving electricity
The cavity of machine.Mounting bracket 2 and subframe 1 are aluminum alloy material.
In the present embodiment, two of which mounting bracket 2 is spaced apart and is taken shape on front-axle beam 11 by casting integrated, another
A (i.e. third) mounting bracket 2 is welded on the back rest 12.Because the back rest 12 of the present embodiment is extrusion forming, therefore it is set to the back rest 12
On mounting bracket 2 can not be taken shape on the back rest 12 by casting integrated.But relative to existing that all mounting brackets 2 are equal
Two mounting brackets 2 of the mode being welded on subframe 1, the present embodiment are taken shape in by casting integrated on subframe 1, still
1 weight of subframe can be mitigated and improve the connectivity robustness of mounting bracket 2 and subframe 1.
Above three mounting bracket 2 is arranged in triangle, makes motor is firm to be installed on subframe 1.Preferably, three installations
Line between holder 2 is in equilateral triangle, can further increase the stability of motor installation.
Include two mounting plates 21 being oppositely arranged, installation by the casting integrated mounting bracket 2 taken shape on front-axle beam 11
21 one end of plate takes shape on front-axle beam 11, and the other end extends outwardly.It is worn for rubber bushing 3 as shown in figure 4, mounting plate 21 is equipped with
Mounting hole 211, rubber bushing 3 passes through and mounting hole 211 and is secured by bolts on mounting plate 21, and motor is installed on rubber lining
On set 3, filtered motor is alleviated by rubber bushing 3 and is transmitted to the vibrations of the part on subframe 1.
To mitigate the weight of mounting plate 21 and the intensity of mounting plate 21 and rigidity can be made to meet the requirements, mounting plate 21 designs
For the structure of variable cross-section thickness, i.e., section thickness is different everywhere in mounting plate 21, the position of the neighbouring subframe 1 of mounting plate 21
Section thickness is more than the section thickness at the position far from subframe 1, i.e. the section thickness of the lower part of mounting plate 21 is more than top
Section thickness.In the present embodiment, the maximum cross-section thickness of the lower part of mounting plate 21 is 12mm, and the smallest cross-sectional thickness on top is
6mm.So the thickness of key position can be designed thickness a bit, and unessential position be designed thinner.
To further increase the rigidity of mounting plate 21, the outside of mounting plate 21 forms reinforcing plate 22,22 one end of reinforcing plate
It takes shape on mounting plate 21, the other end is tilted to 1 direction of subframe to be extended and take shape on subframe 1.The reinforcing plate 22 is set to
The key position of mounting plate 21.
The mounting bracket 2 and subframe 1 of the present embodiment are aluminum alloy material, can not only mitigate the weight of entire assembly,
Increase the course continuation mileage of electric vehicle, and convenient for mounting plate 21 is designed to that lower section thickness is big, top section thickness is small
Structure is also convenient for designing reinforcing plate 22 in 21 outside of mounting plate.
