Embodiment 1

[0027] Embodiment one, see figure 1 , a rear vibration isolation battery pack installation structure for an electric vehicle, comprising a vehicle floor 3 and a front bumper 1 .

[0028] The car floor 3 is positioned between the front of the trunk behind the car and the rear of the rear seat during use. Both sides of the automobile floor 3 are provided with a connecting column 31 .

[0029] The front bumper 1 is a tubular structure, specifically a stainless steel tube. The front bumper 1 extends in the width direction of the vehicle. Front bumper 1 is positioned at the rear of the rear row seat of automobile. The front bumper 1 is connected with five battery pack fixing mechanisms 4 . The five battery pack fixing mechanisms 4 are distributed along the length direction of the front bumper 1 , that is, the width direction of the vehicle. The battery pack fixing mechanism 4 includes a connection base 41 and a first suction cup 42 connected to the rear side of the connection b...

Embodiment 2

[0035] Embodiment two, the difference with embodiment one is:

[0036] see Image 6 , the connecting frame 9 is connected with a heat preservation mechanism 8 . The connecting frame 9 also includes a connecting rod 91 and five damping 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 longitudinal damping rod 921 , two horizontal damping rods 922 and two vertical damping rods 923 . One end of the connecting rod 91 is connected with the connecting post 31 . The other end of the connecting rod 91 is connected with one end of the longitudinal damping rod 921 . One end of the two transverse damping rods 922 and the other end of the longitudinal damping rod 921 are connected together. The upper ends of the two vertical damping rods 923 are respectively connected with the other ends of the two transverse damping rods 922 . The lower ends of the two vertical damping rods 923 are ...

Abstract

The invention relates to the technical field of manufacturing of new energy automobiles. A rear vibration isolation electric vehicle battery pack installation structure comprises a front stop lever and an automobile floor positioned between a trunk and back seats, wherein the front stop lever is of a tubular structure; the front stop lever extends along the width direction of an automobile; the front stop lever is provided with a plurality of battery pack fixing mechanisms along the length direction of the front stop lever; each battery pack fixing mechanism comprises a connection seat connected together with the front stop lever, a first suction cup connected to the back side of the connection seat and a second suction cup positioned in the first suction cup; the first suction cups and the second suction cups define adsorption tanks; two ends of the front stop lever are connected with connection frames which are connected together with the automobile floor. The rear vibration isolation electric vehicle battery pack installation structure has the advantages of capability of preventing a battery pack from being overturned and good vibration isolation effect, and the problems that the battery pack is easily overturned in bumps of the existing battery pack installation structure installed at the rear and the vibration isolation effect is poor are solved.

Description
