Embodiment 1

[0035] like Figure 1-5 As shown, a suspension bracket for improving crash performance includes: a first sub-frame mounting portion 1, a suspension front arm 2 and a powertrain mounting portion 3, the suspension forearm 2 is fixedly connected to the first sub-frame Between the mounting portion 1 and the powertrain mounting portion 3, the first subframe mounting portion 1 is used to be fixedly connected to the subframe 4 of the automobile, and the powertrain mounting portion 3 is used to be fixed with the powertrain 5 of the automobile Connected, the suspension bracket is arranged to break at the suspension front arm 2 when the powertrain 5 of the car is squeezed on the suspension front arm 2 . Generally, when a car collides, the power assembly 5 is squeezed on the suspension front arm 2 due to the transmission of the force generated by the collision to the power assembly 5 in the car.

[0036]It should be noted that, in the structure of the automobile in the prior art, the su...

Embodiment 2

[0047] like Figure 4-5 As shown, a powertrain structure includes a powertrain 5, a subframe 4 and a suspension bracket for improving crash performance in Embodiment 1. The suspension bracket is fixedly installed on the subframe 4, and the powertrain The component 5 is fixedly connected to the suspension bracket through the powertrain mounting part 3 . The suspension bracket in Embodiment 1 is used in the powertrain structure, so that the suspension bracket of the powertrain structure is broken when the front part of the vehicle collides, and the Z-direction collision and sinking of the powertrain 5 are induced, which effectively solves the problem. The common problem of excessive deformation of the front wall structure of the body due to the impact of the powertrain 5 reduces the degree of injury to the occupants.

Embodiment 3

[0049] An automobile, including the powertrain structure in Embodiment 2, effectively improves the crash performance of the automobile in a frontal collision, increases the living space in the passenger compartment, and provides a very effective frontal collision for many models developed in the later stage. development strategy.

[0050] As mentioned above, the present invention has the following beneficial effects:

[0051] 1) By designing the suspension bracket into a collision fracture structure, the suspension bracket is broken when the car collides, which improves the collision performance of the car, reduces the collision of the car's powertrain and squeezes the front wall structure of the body, and ensures the passenger compartment. The living space inside the vehicle solves the problem in the prior art that when the vehicle collides, the powertrain of the vehicle squeezes the occupant compartment and severely deforms, causing serious collision damage to the occupants ...

Abstract

The invention relates to a suspension support used for improving collision performance, a power assembly structure and an automobile. The suspension support comprises a first auxiliary frame mounting part, a suspension front arm and a power assembly mounting part, wherein the suspension front arm is fixedly connected between the first auxiliary frame mounting part and the power assembly mounting part, the first auxiliary frame mounting part is used for being fixedly connected to an auxiliary frame of an automobile, the power assembly mounting part is used for being fixedly connected with a power assembly of an automobile, and the suspension support is arranged to be broken at the suspension front arm when the power assembly of the automobile is extruded on the suspension front arm. The suspension support is designed into a collision fracture structure, so the suspension support is fractured when the automobile is collided, and the power assembly of the automobile is prevented from colliding and extruding an automobile body front wall structure; a problem that in the prior art, when the automobile is collided, the power assembly of the automobile extrudes a passenger compartment and seriously deforms, and passengers in the automobile are seriously collided and hurt is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a suspension bracket, a power assembly structure and an automobile for improving crash performance. Background technique [0002] In this era of industrial globalization, the development of the automobile industry is very mature. With the continuous development of the global economy and the increase of people's travel needs, automobiles have become an indispensable means of transportation, and automobiles have brought a lot of convenience to people's travel. It has brought unprecedented opportunities to the consumer market of automobiles, the number of family vehicles has been unprecedentedly increased, and in the opposite direction, the further development of the automobile industry has been promoted. However, the problems brought about by the development of the automobile industry are also obvious, and the number of traffic accidents is also increasing. The common traffic a...
