To reduce the injury to the driver and passengers, the frame structure of the vehicle needs to have a certain rigidity and to sufficiently absorb the collision energy.
A special collision energy absorption area is not usually arranged behind a driver area of an existing passenger car, and collision energy is absorbed through the way that a front axle frame body is integrally deformed to absorb energy.

Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, unless otherwise stated, terms of orientation such as "up, down, left, right, front, and rear" are used with respect to a state in which the vehicle normally travels, specifically, when the vehicle normally travels, a direction toward the head of the vehicle is "front", a direction toward the tail of the vehicle is "rear", a direction toward the ceiling is "up", a direction toward the floor is "down", a direction toward the left wheel is "left", and a direction toward the right wheel is "right", and in the present disclosure, an extending direction of "side members" is in a front-rear direction of the vehicle, an extending direction of "cross members" is in a left-right direction of the vehicle, "X direction" is a front-rear direction of the vehicle, and an "X-direction plane" is a plane perpendicular to the X direction; the "Y direction" refers to the left-right direction of the vehicle, and the "Y direction plane" refers to a plane perpendicular to the Y direction.
As shown in fig. 1 to 5, the present disclosure provides a front frame, for example, a front frame for a passenger car, the front frame includes a driver area 1 and a collision energy absorption area 3, a step area 2, and a battery area 4, the step area 2 can be used for installing a step and a front door of the passenger car, so that passengers can enter the passenger car, the step area 2 is located on the left or right side of the driver area 1, the battery area 4 is used for installing a battery, so as to supply power to electric equipment of the passenger car, the battery area 4 can be located behind the step area 2, and the collision energy absorption area 3 is used for absorbing collision energy and reducing the acceleration of the passenger car. In an exemplary embodiment provided by the present disclosure, the energy-absorbing impact zone 3 is located behind the driver zone 1 and in front of the passenger zone (not shown), the longitudinal strength (the ability to resist deformation and fracture when subjected to a longitudinal external force) of the energy-absorbing impact zone 3 is less than that of the driver zone 1, and when a frontal collision occurs in the vehicle, the impact force is transmitted to the energy-absorbing impact zone 3 through the driver zone 1, so that the energy-absorbing impact zone 3 deforms to absorb the impact energy.
Thus, when the passenger car is in direct collision, because the longitudinal strength of the collision energy-absorbing area 3 is smaller than that of the driver area 1, the collision energy-absorbing area 3 can deform in preference to the driver area 1 to absorb most of collision energy, so that the deformation of the driver area 1 and a passenger area (positioned behind the collision energy-absorbing area 3 and not shown in the figure) is reduced, the overall rigidity and strength of the driver area 1 of the front frame are improved, and the life safety of the driver and the passengers is ensured.

In addition, because the front end of the driver area force transmission inclined beam is higher than the rear end of the driver area force transmission inclined beam, the driver area force transmission inclined beam is easy to bend under stress in the collision process, in order to enhance the rigidity and the bending resistance of the driver area force transmission inclined beam, the cross section of the driver area force transmission inclined beam can be formed into a hollow rectangular structure, and a reinforcing plate 9 is arranged inside the driver area force transmission inclined beam. Thus, the rigidity and the strength of the lower part of the driver area 1 can be enhanced, and the rigidity and the strength of the lower part of the driver area 1 can be close to or equal to the rigidity and the strength of the upper part of the driver area 1, so that the integrity of the driver area 1 is ensured, and the possibility of bending of each longitudinal beam of the driver area 1 is reduced.

Due to the existence of the structures such as the front vehicle door, the steps, the storage battery and the like, the longitudinal rigidity and the longitudinal strength of the right side of the front vehicle frame are smaller than those of the left side, namely, the longitudinal rigidity and the longitudinal strength of the step area 2 and the storage battery area 4 are smaller than those of the driver area 1, when frontal collision occurs, the step area 2 and the storage battery area 4 are easy to deform and generate bending moment, so that each longitudinal beam in the driver area 1 is bent, the longitudinal rigidity and the longitudinal strength of the driver area 1 are reduced, and the front vehicle frame deforms integrally. Therefore, in the exemplary embodiment provided by the present disclosure, as shown in fig. 1 and 2, the front frame may further include a stepped region force transfer longitudinal beam 21 to enhance the longitudinal rigidity and the longitudinal strength of the stepped region 2, the stepped region force transfer longitudinal beam 21 is located between the first right longitudinal beam 161 and the center longitudinal beam 150, the front end of the stepped region force transfer longitudinal beam 21 is connected to the front cross member 100, and the rear end of the stepped region force transfer longitudinal beam 21 is connected to the second center cross member 110.

Further, in order to improve the longitudinal rigidity and the longitudinal strength of the battery region 4, the width of the second right side member 162 may be increased, or a reinforcing plate 9 may be provided also inside the second right side member 162. Thus, the longitudinal rigidity and the longitudinal strength of the stepped region 2 and the battery region 4 can be improved, the longitudinal rigidity and the longitudinal strength of the stepped region 2 and the battery region 4 can be made to be close to or equal to the longitudinal rigidity and the longitudinal strength of the driver region 1, and the possibility of deformation of the entire front frame can be reduced.
