With the development of science and technology, higher requirements are put on various performances of automobile products. In current automotive designs, three electrical systems (including batteries, motors and electrical controls) are typically mounted and secured directly to the stringers by way of transition brackets. When the car body is stressed along the lateral direction or impacted, the lateral supporting force of the longitudinal beam to the transition bracket is weak, so that the three-electric system is easy to damage.
Referring to fig. 1-4, in order to solve the problem that the lateral supporting force is weak in the existing installation structure of the three-electric system, the application provides a supporting beam assembly structure. The support beam assembly structure includes a first body rail 100, a second body rail 200, a first connection bracket 400, a second connection bracket 500, and a body cross member 300. The three-dimensional coordinate system is defined to include an X-axis, a Y-axis, and a Z-axis perpendicular to each other, wherein the first body side member 100 and the second body side member 200 each extend along the X-axis direction and are disposed at intervals, and the body cross member 300 extends along the Y-axis direction. One end of the body cross member 300 is mounted to the first body side member 100 by the first connection bracket 400, and the orthographic projection of the body cross member 300 in the XZ plane and the orthographic projection of the first body side member 100 in the XZ plane are at least partially overlapped. The other end of the body cross member 300 is mounted to the second body side member 200 by a second connection bracket 500, and the orthographic projection of the body cross member 300 in the XZ plane and the orthographic projection of the second body side member 200 in the XZ plane at least partially overlap. The three-electric system is mounted to the first body rail 100 and the second body rail 200 by the body cross member 300.
The XZ plane refers to a plane formed by the X axis and the Z axis, and since the X axis, the Y axis, and the Z axis are perpendicular to each other, the Y axis is perpendicular to the XZ plane.
When the vehicle body is subjected to stress or impact in the lateral direction (i.e., the Y-axis direction), since the three-electric system is mounted to the first body side member 100 and the second body side member 200 through the body cross member 300 and the mass of the three-electric system is large, the three-electric system impacts the first body side member 100 or the second body side member 200 with the body cross member 300 in the Y-axis direction. When the three-electric system impacts the first body side member 100 along the Y-axis direction with the body cross member 300, since the orthographic projection of the body cross member 300 in the XZ plane and the orthographic projection of the first body side member 100 in the XZ plane are at least partially overlapped, under the blocking effect of the projection overlapping portion of the body cross member 300 and the first body side member 100, the large impact force of the body cross member 300 along the Y-axis direction can be directly stopped by the first body side member 100, so that the body cross member 300 and the first body side member 100 are not dislocated along the Y-axis direction. Similarly, when the three-electric system impacts the second body side member 200 along the Y-axis direction with the body cross member 300, since the front projection of the body cross member 300 in the XZ plane and the front projection of the second body side member 200 in the XZ plane are at least partially overlapped, the large impact force of the body cross member 300 along the Y-axis direction can be directly stopped by the second body side member 200 under the blocking action of the projected overlapped portion of the body cross member 300 and the second body side member 200, so that the body cross member 300 and the second body side member 200 are not dislocated along the Y-axis direction.
From the above, compare when the crossbeam is installed in the top of longeron, dislocation takes place for crossbeam and longeron under the effect of the impact force of Y axle direction easily, the supporting beam assembly structure that this application provided has greatly improved the automobile body to the Y axial supporting role of three electric system, and then has improved new energy automobile's security.
Further, compared to the transition bracket, the first connection bracket 400 and the second connection bracket 500 have smaller volume and lighter weight, which greatly reduces the energy consumption of the new energy automobile and is beneficial to the lightweight design of the new energy automobile.
Further, in an embodiment, the orthographic projection of the first body rail 100 in the XZ plane completely covers the orthographic projection of the body cross member 300 in the XZ plane. In this way, the end surface of the body cross beam 300, which is close to the first body longitudinal beam 100, can be directly or indirectly in full contact with the first body longitudinal beam 100, so that the direct or indirect contact area between the body cross beam 300 and the first body longitudinal beam 100 along the Y-axis direction is increased, the pressure intensity between the body cross beam 300 and the first body longitudinal beam 100 is reduced, and the risk of damage to the support beam assembly structure is reduced.
Likewise, in one embodiment, the orthographic projection of the second body rail 200 in the XZ plane completely covers the orthographic projection of the body rail 300 in the XZ plane. In this way, the end surface of the vehicle body cross beam 300, which is close to the second vehicle body longitudinal beam 200, can be directly or indirectly in full contact with the second vehicle body longitudinal beam 200, so that the direct or indirect contact area between the vehicle body cross beam 300 and the second vehicle body longitudinal beam 200 along the Y-axis direction is increased, the pressure intensity between the vehicle body cross beam 300 and the second vehicle body longitudinal beam 200 is reduced, and the risk of damage to the assembly structure of the support beam is reduced.

Generally, the shapes and the installation angles of the body cross member 300 and the first body side member 100 are different, and therefore, the installation difficulty of the body cross member 300 and the first body side member 100 is greatly reduced by providing the first connecting portion 410 and the second connecting portion 420 to connect the body cross member 300 and the first body side member 100, respectively.
Specifically, in one embodiment, as shown in fig. 2 to 4, the body cross member 300 is detachably attached to the first attachment portion 410 by the fastener 600, so that the attachment and detachment between the body cross member 300 and the first attachment portion 410, that is, the attachment and detachment between the body cross member 300 and the first body side member 100 are facilitated.
