Technical Field
The present invention relates to the field of automotive technology, and more particularly, to a force transmission system for a rear body collision and an automobile provided with the force transmission system.
Background
With the development of the times, automobiles gradually enter thousands of families and become daily necessities of many families. The safety of automobiles is a particular concern for every purchaser.
In general, when a rear collision occurs, an external force is transmitted to a longitudinal beam member through a tail extrusion member and then transmitted to a vehicle body, so that the purpose of dispersing the external force is achieved, but for the vehicle body made of all-aluminum alloy, a great improvement space still exists for the force transmission path because of weaker structural strength of the force transmission path. In addition, the above-described force transmission path often directly applies the external force transmitted from the side member to the rocker, and does not satisfactorily utilize other components in the vehicle body to disperse the collision force. There is therefore a need for a force transmission system for a rear body collision that is capable of effectively transmitting and dispersing collision energy.
Disclosure of Invention
In view of the above, it is an object of the present invention to provide a force transmission system for a rear body collision, which effectively solves the above-mentioned problems and other problems occurring in the prior art. In the force transmission system according to the invention, the force transmission system may carry a force transmission path comprising a subframe, an elastic buffer and a reinforcement plate connected in sequence, wherein the subframe transmits a collision impact force to the reinforcement plate through the elastic buffer and then the reinforcement plate transmits the collision impact force to a rocker.
In the above force transmission system, preferably, the elastic buffer is a suspension.
In the above force transmission system, preferably, the force transmission system may further carry an auxiliary force transmission path including a tail extrusion member, a side member, and a seat slide member connected in sequence.
In the above force transmission system, preferably, the tail extrusion and the side member are connected by a fastener.
In the above force transmission system, preferably, the tail extrusion and the side member are made of an aluminum alloy, and the reinforcing plate and the seat rail member are made of steel.
In the above force transmission system, preferably, the suspension member includes an elastic member and an aluminum alloy block.
In the above force transmission system, preferably, the number of the suspension members is at least four.
In the above force transmission system, preferably, the elastic member is made of rubber.
Furthermore, according to a second aspect of the present invention, there is also provided an automobile provided with the above-described force transmission system for a rear-body collision.
In the above-described automobile, preferably, the automobile is an automobile employing an aluminum alloy body.
In the above-described automobile, preferably, the automobile is an electric automobile.
It can be appreciated that the force transmission system for rear car body collision effectively distributes the impact force of the whole car high-speed rear collision on the corresponding parts, finally achieves the structural safety of the whole car high-speed rear collision, and simultaneously advantageously protects the safety of passengers in the car.
Drawings
The technical scheme of the invention will be further described in detail below with reference to the attached drawings and detailed description, wherein:
FIG. 1 is a schematic structural view of a specific embodiment of a force transmission system for a rear body collision of the present invention; and
fig. 2 is a schematic illustration of the force transmission path of the force transmission system for a rear body collision of fig. 1.
Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings.
One embodiment of the force transmission system for a rear body collision of the present invention is shown in fig. 1. As can be seen in connection with fig. 2, the force transmission system can carry a force transmission path and the force transmission path comprises a subframe 2, an elastic buffer (not shown) and a reinforcing plate 4 which are connected in sequence, wherein the subframe 2 transmits the collision impact force to the reinforcing plate 4 through the elastic buffer and then the reinforcing plate 4 transmits the collision impact force to other parts of the vehicle body such as a door sill 6, so that the force transmission path effectively carries the impact force generated during a rear vehicle body collision. Preferably, the reinforcing plate 4 may be made of a high-strength steel plate. It is easy to understand that the subframe 2, the elastic buffer and the reinforcement plate 4 all belong to the chassis module of the automobile.
With continued reference to fig. 1, the force transmission system may further carry an auxiliary force transmission path, where the auxiliary force transmission path includes a tail extrusion 1, a longitudinal beam member 3, and a seat slide rail member 5 that are sequentially connected, so that an impact force generated during a rear vehicle body collision is transmitted between the tail extrusion 1, the longitudinal beam member 3, and the seat slide rail member 5, thereby achieving the effects of dispersing an external force and protecting a vehicle body. Preferably, the tail extrusion 1 and the side member 3 may be extruded from a material such as an aluminum alloy, and the seat rail 5 may be made of a high-strength steel plate. It is easy to understand that the tail extrusion 1 and the longitudinal beam 3 belong to a body module of an automobile; the seat rail element 5 belongs to a seat module of a motor vehicle.
In other preferred embodiments in combination with the above embodiments, the elastic buffer in the force transmission path is preferably designed as a suspension, and the suspension comprises an elastic member made of rubber and an aluminum alloy block, for example. Optionally, the number of the suspension elements is four. The man skilled in the art can adjust the number of suspensions, for example five, six, seven, etc., according to the actual need or the geometry of the chassis, without being limited to the four mentioned above.
It will be readily apparent to those skilled in the art that in the force transmission system for a rear vehicle body collision of the present invention, the side member 3 and the seat rail member 5 may be connected by a fastener such as a bolt. Of course, the manner of connection between these components is not limited to the above-described bolting.
The invention also relates to a motor vehicle comprising the force transmission system for a rear-body collision. The automobile is an automobile adopting an aluminum alloy automobile body preferably. Of course, other bodies than aluminum alloy bodies that utilize non-conventional body materials may also utilize the force transfer system provided in accordance with the present invention. Optionally, the automobile is an electric automobile.
In summary, the force transmission system for rear-body collision of the invention fully utilizes all the sub-modules (namely the vehicle body module, the chassis module, the seat module and the like) of the whole vehicle, solves the force transmission problem of the low-rigidity vehicle body structure, well controls the deformation of the rear-body collision of the whole vehicle and ensures the structural safety of the whole vehicle. It is therefore highly recommended to popularize and apply such force transmission systems for rear body collisions in vehicles, in particular electric vehicles.
The above description of the specific embodiments of the present invention has been provided to illustrate in detail the force transmission system for a rear body collision and the automobile provided with the force transmission system, these examples are for the purpose of illustrating the principle of the present invention and its embodiments, and not for the purpose of limiting the invention, and various modifications and improvements may be made by those skilled in the art without departing from the spirit and scope of the invention.
