Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0030] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way that one element is fixedly connected to another element can be realized through existing technologies, and will not be discussed here. To repeat it agai...

The invention relates to a force transmission structure, an automobile body frame and an automobile. The force transmission structure comprises a front longitudinal beam, a front longitudinal beam rear plate, a front coaming, a front coaming cross beam, an A column inner plate, an inclined support and a doorsill beam, wherein a root of the front longitudinal beam is connected with the front longitudinal beam rear plate; the front coaming is arranged on the front coaming cross beam, and the front coaming cross beam is connected with the front longitudinal beam rear plate; the A column inner plate is connected with the front coaming and the front longitudinal beam rear plate; the inclined support is obliquely arranged on the front coaming, and the two ends of the inclined support are connected with the front longitudinal beam rear plate and the A column inner plate respectively; and the doorsill beam is connected with the front longitudinal beam rear plate. A part of impact force can beeffectively transmitted to the A column inner plate from the root of the front longitudinal beam through the front longitudinal beam rear plate and the inclined support so that a stress burden of thefront longitudinal beam rear plate is reduced, and the front longitudinal beam rear plate is effectively prevented from collapsing and embrittlement. A force transmission characteristic of a vehicle body during collision can be improved, a cracking degree caused by collision is reduced, and structural stability and integrity of the automobile body are improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a force transmission structure, a body frame and an automobile. Background technique [0002] At present, automobiles usually adopt a steel body structure. In order to improve the strength of the body structure and the impact resistance, it is necessary to strengthen the front wall cross member lapped by the A-pillar. However, the essence of strengthening the front wall beam is only to strengthen the local structure of the vehicle body, which cannot improve the force transmission characteristics, and cannot improve the structural strength of the vehicle body so as to reduce the degree of cracking of the vehicle body when it is hit. Contents of the invention [0003] Based on this, it is necessary to provide a force transmission structure that can improve the force transmission characteristics of the vehicle body when it is collided, reduce the degree of cracking caused by t...
