[0019] As Figs. 1-3 Indicated, a car body sheet metal part structure, including with horizontal side wall 1 steel frame, and the outer wall of one side of horizontal side wall 1 symmetrically set up vertical to the vertical plate 11 of horizontal side wall 1 outer wall, set up aluminum alloy support assembly between two vertical plates 11, aluminum alloy support assembly includes square tube 4 and the buffer plate piece at the opposite two sides of square tube 4, two vertical plates 11 are inserted with bolt piece 3 that penetrates square tube 4 and two buffer plate pieces. Through the steel structure of steel frame, so as to ensure that the battery tray sheet metal part has a certain strength basis, and then utilize the vertical plate 11 that is symmetrically set up on horizontal side wall 1 vertical to horizontal side wall 1, so that horizontal side wall 1 has a certain bending resistance, and then utilize aluminum alloy support assembly set up between two vertical plates 11, to further support horizontal side wall 1, simultaneously adopt aluminum alloy material to reduce the weight, and utilize bolt piece 3 and penetrate square tube 4 and two buffer plate pieces, to further realize the quick fixing of aluminum alloy support assembly, so by adjusting the thickness of horizontal side wall 1 and the thickness of aluminum alloy support assembly, so as to combine the structural strength of horizontal side wall 1 steel material, while the use of aluminum alloy support assembly, can reduce the use of horizontal side wall 1 steel material to reduce the weight, while ensuring the structural strength of battery tray sheet metal part.

[0020] As the further provided technical scheme of the utility model, square tube 4 includes two parallel plates 42 that are symmetrically set up and parallel to vertical plate 11, and square tube 4 further includes two vertical plates 41 that are symmetrically set up and respectively parallel to horizontal side wall 1.

[0021] Specifically, as Fig. 3As shown, by utilizing two parallel plates 42 and vertical plate 11 parallel to enhance the support strength of the horizontal direction of the lateral wall 1, and by two vertical plates 41 and the lateral wall 1 parallel to enhance the vertical support strength of the vertical plate 11.

[0022] Further, the buffer plate member includes the base plate 2 parallel to the vertical plate 11 and the inclined plate 21 arranged obliquely, the two inclined plates 21 between the two vertical plates 11 are inclined to approach each other, and the buffer plate member further includes the curved plate 22 arranged on one side of the inclined plate 21, the two curved plates 22 between the two vertical plates 11 are arranged symmetrically adjacent to each other, the curved plate 22 and the outer wall of the vertical plate 41 on the square tube 4 maintain a predetermined interval, and the two curved plates 22 maintain a predetermined interval.

[0023] Specifically, by utilizing the two inclined plates 21 between the two vertical plates 11 to be inclined to approach each other, so that the two inclined plates 21 can approach and extrude deformation when subjected to horizontal force, thereby achieving a certain buffering effect. By utilizing the base plate 2 and the vertical plate 11 of the buffer plate member to be parallel, so as to be penetrated by the bolt member 3 and fixed between the two vertical plates 11 and the square tube 4 at the same time, and by utilizing the two curved plates 22 to maintain a predetermined interval, and the two curved plates 22 and the outer wall of the vertical plate 41 on the square tube 4 maintain a predetermined interval, so as to approach each other through the end of the two inclined plates 21 when the two inclined plates 21 are extruded, so that the two curved plates 22 are attached to each other, and the extrusion of the inclined plate 21 is buffered, and in the process of extruding the two vertical plates 11 and approaching the square tube 4, the two curved plates 22 are driven to approach the outer wall of the vertical plate 41 of the square tube 4, so as to block the curved plate 22 by the vertical plate 41, at this time, the two vertical plates 11 and the two curved plates 22 are displaced and deformed at the same time to buffer, as shown in Fig. 3 As shown, the force point of the two curved plates 22 on the vertical plate 41 is the middle region of the vertical plate 41, and the middle region of the vertical plate 41 lacks support, so when the vertical plate 41 is extruded, the vertical plate 41 will deform to buffer the extrusion force of the two vertical plates 11, and then when the inclined plate 21, the curved plate 22 and the vertical plate 41 are severely deformed, the two vertical plates 11 and the lateral wall 1 are used to bear the extrusion force. By utilizing the inclined plate 21, the curved plate 22 and the vertical plate 41 to be sequentially stressed and deformed, the lateral extrusion force of the lateral wall 1 is buffered, and the impact force on the lateral wall 1 is reduced. The buffer plate member composed of the base plate 2, the inclined plate 21 and the curved plate 22 is a whole plate member, which is convenient for processing. The square tube 4 composed of the vertical plate 41 and the parallel plate 42 is a whole tube member, which is convenient for processing. By utilizing the bolt member 3 to quickly fix the buffer plate member and the square tube 4, the installation is facilitated.

[0024] Further, the bolt member 3 is a plurality of, and the nut member 31 is arranged on the screw thread of the bolt member 3.

[0025] Specifically, the two vertical plates 11 can be supported by the plurality of bolt members 3, and the plurality of bolt members 3 can make the buffer plate member and the square tube 4 more stable. The buffer plate member and the square tube 4 are fixed by screwing the nut member 31 on the bolt member 3.

[0026] Furthermore, the bolt member 3 is an aluminum alloy bolt.

[0027] Specifically, the aluminum alloy bolt is lighter than a steel bolt, thereby further reducing the weight. When the bolt member 3 is close to the vertical plate 41 on one side of the curved plate 22 during use, the deformation of the vertical plate 41 acts on the bolt member 3 when the curved plate 22 extrudes the vertical plate 41, thereby using the deformation of the bolt member 3 to further buffer the extrusion force received by the vertical plate 11.

[0028] Working principle: The steel material structure of the steel frame ensures that the battery tray sheet metal part has a certain strength basis. The vertical plate 11 symmetrically arranged on the lateral wall 1 is perpendicular to the lateral wall 1, so that the lateral wall 1 has a certain bending resistance. The aluminum alloy support assembly arranged between the two vertical plates 11 is used to further support the lateral wall 1. The aluminum alloy material is used to reduce the weight. The bolt member 3 penetrates the square tube 4 and the two buffer plate members at the same time, thereby achieving rapid fixing of the aluminum alloy support assembly. Further, the two inclined plates 21 between the two vertical plates 11 are inclined to approach each other, so that the two inclined plates 21 can approach and extrude each other when subjected to horizontal force, thereby achieving a certain buffering effect. The base plate 2 and the vertical plate 11 of the buffer plate member are parallel, so that they are penetrated by the bolt member 3 and fixed between the two vertical plates 11 and the square tube 4 at the same time. By maintaining a predetermined distance between the two curved plates 22 and a predetermined distance between the outer wall of the vertical plate 41 on the square tube 4, the two curved plates 22 can be extruded by the two inclined plates 21 when the two inclined plates 21 are extruded. The two curved plates 22 approach each other to abut each other, and buffer the extrusion of the inclined plate 21. When the two vertical plates 11 are extruded and approach the square tube 4, the two curved plates 22 approach the outer wall of the vertical plate 41 of the square tube 4, thereby using the vertical plate 41 to block the curved plate 22. At this time, the two vertical plates 11 and the two curved plates 22 are displaced and deformed at the same time to buffer, such as Fig. 3As shown, the force points of the two curved plates 22 on the vertical plate 41 are the middle regions of the vertical plate 41, and the middle regions of the vertical plate 41 lack support, so when the vertical plate 41 is pressed, the vertical plate 41 will deform to buffer the pressing force received by the two vertical plates 11, and then when the deformation of the inclined plate 21, the curved plate 22 and the vertical plate 41 is more serious, at this time the two vertical plates 11 and the horizontal side wall 1 are used to bear the pressing force. By using the force deformation of the inclined plate 21, the curved plate 22 and the vertical plate 41 in turn, the lateral pressing force received by the horizontal side wall 1 is buffered, and the impact force on the horizontal side wall 1 is reduced.
