Embodiment 1

[0023] Embodiment one, see figure 1, an electric vehicle powertrain installation structure with a profile structure, including a bracket 1 . The bracket 1 is a plate-like structure. Bracket 1 is made of aluminum alloy profile. Bracket 1 is a linear structure extending perpendicular to the cross-sectional direction of the profile for making the bracket. The bracket 1 includes a panel 11 , a bottom plate 12 and a support bar 13 . The support bar 13 is a linear structure. There are 10 support bars 13. The support bar 13 is supported between the bottom plate 12 and the panel 11 . The panel 11 , the bottom plate 12 and the support bar 13 are integrally structured. Nine shock-absorbing channels 14 with open ends are formed between the base plate 12, the panel 11 and the support bar 13 (as long as there are two or more, there is an anti-resonance effect, if there is no one). Both ends of the bracket 1 along the extending direction of the support bar 13 are provided with hangin...

Embodiment 2

[0025] Embodiment two, see figure 2 , the bracket 1 is the same as that in the first implementation, and the bracket is only schematically drawn in the figure. The difference between the second embodiment and the first embodiment is that it further includes two suspension frames 9 and two coating heating mechanisms 8 .

[0026] The two suspension frames 9 are connected to the two suspension parts 15 in one-to-one correspondence. The suspension frame 9 includes a connecting rod 91 and five shock absorbing rods 92 . The connecting rod 91 is an arc-shaped structure that arches upwards (of course, downwards is also possible). The five damping rods 92 are a horizontal damping rod 921 , two longitudinal damping rods 922 and two vertical damping rods 923 . One end of the connecting rod 91 is connected with one end of the transverse damping rod 921 . One end of the two longitudinal damping rods 922 and the other end of the transverse damping rod 921 are connected together. The u...

Abstract

The invention relates to an electric car, and provides an electric car power assembly installing structure which is of a profile structure. The electric car power assembly installing structure which is of the profile structure comprises a bracket. The bracket is of a tabular structure. The bracket is made of extrudates. An electric car power assembly is only supported by the bracket. The electric car power assembly comprises a motor and a gearbox. The bracket comprises a face plate, a base plate and at least three straight-line-shaped supporting strips supported between the bottom plate and the face plate. An integral structure is formed by the face plate, the base plate and the supporting strips. At least two shock absorption channels with two open ends are formed by the base plate, the face plate and the supporting strips. The two ends, along the extending direction of the supporting strips, of the bracket are provided with suspension parts. According to the electric car power assembly installing structure which is of the profile structure, the strength requirement can be met at a low weight, the resonance phenomenon is not likely to occur, and manufacturing is convenient. The problems in an existing power assembly installing structure capable of carrying out independent supporting on the power assembly that the weight is heavy, manufacturing is inconvenient, and the resonance is likely to occur are solved.

Description

technical field [0001] The invention relates to electric vehicles, in particular to an electric vehicle power assembly installation structure with profile structure. Background technique [0002] The powertrain of electric vehicles includes motors, transmissions, chargers, motor controllers, heat pumps and junction boxes, etc. Since the electric vehicle is developed and improved on the basis of the original fuel engine vehicle, in order not to affect the occupant space of the original vehicle and the comfort of the whole vehicle, the components of the powertrain are arranged in the front compartment of the vehicle. In the Chinese patent application number 2014100362322, the publication date is April 16, 2014, and the patent document titled "A Suspension System for Electric Vehicle Powertrain" discloses the above-mentioned installation structure of an electric vehicle powertrain . The above connection methods have the disadvantages that the powertrain and other parts of the...
