Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details.

Referring to fig. 1 and 2, the stand column for the passenger car comprises an aluminum profile body 11, wherein the cross section of the aluminum profile body 11 is approximately rectangular, a cavity 12 is arranged in the middle of the aluminum profile body along the axis direction, and a groove 13 is arranged on the left side and the right side of the aluminum profile body. When the aluminum profile body 11 is applied to a passenger car body structure, rivets or bolts can be arranged at the grooves 13 on the two sides to form a connectable structure, and the connectable structure is connected with corresponding connecting pieces. The upper surface and the lower surface of the aluminum profile body 11 are mainly positioned on the inner side and the outer side of the vehicle and are designed into planes which can facilitate the bonding of glass, window frames, side skins and the covering of interior trim parts made of different materials. Therefore, the utility model discloses but wide application in passenger train window stand, side wall stand, wheel casing stand and storehouse stand etc. a plurality of aluminium alloy body 11 can also splice together, constitutes network structure, undertakes vehicle load, uses top cap skeleton, the left side of passenger train to enclose skeleton and right side and enclose skeleton etc. and both accorded with the production and manufacturing technology characteristics of passenger train small batch, many varieties, can satisfy the demand of passenger train market configuration variety moreover.

Referring to fig. 1 and 2, four outer corners of the cross section of the aluminum profile body 11 are designed to be right angles, so that the aluminum profile body 11 can be conveniently blanked in a machining mode, and can be conveniently connected with other profiles through rivets or bolts, and the manufacturing precision and the manufacturing efficiency can be improved.

Referring to fig. 1 and 2, the cross section of the groove 13 is isosceles trapezoid, and the two grooves 13 are symmetrical to each other. The two grooves 13 are designed into an inward-sinking symmetrical isosceles trapezoid structure, so that the contact area between the aluminum profile body 11 and the connecting piece can be increased, and the uniform stress between the aluminum profile body and the connecting piece is ensured, thereby increasing the structural stability, improving the bending resistance and the torsion resistance of the vehicle, and improving the reliability and the safety of the vehicle.

Referring to fig. 1 and 2, a through hole 14 is formed at each of four corners between the edges of the cross section of the aluminum profile body 11. The arrangement of the through holes 14 can save materials, fully reduce the dead weight of the aluminum profile body 11 and improve the light weight level of the passenger car component. As a preferable scheme: the cross section of each through hole 14 is in a right trapezoid shape, and two adjacent through holes 14 are symmetrical to each other.

Referring to fig. 1 and 2, the wall thickness values of the upper and lower sides 110 of the aluminum profile body 11 are both greater than the wall thickness value between the cavity 12 and the through hole 14 and less than the wall thickness value between the cavity 12 and the groove 13. Specifically, the first side 111 of the aluminum profile body 11 is a fixing side of a rivet or a bolt, which plays a role in connection, and the connection is firmer the larger the thickness value is designed, so the thickness value of the first side 111 is designed to be the largest; the second side edge 112 of the aluminum profile body 11 is in contact with a corresponding connecting piece to play a role in assisting stress, and the wall thickness value can be designed to be a little smaller; the inner edge 113 of the aluminum profile body 11 is connected with the first side edge 111 and the second side edge 112, and can transmit the force applied to the first side edge 111 to the upper and lower sides 110, so that the force is mainly divided, and therefore the wall thickness of the inner edge 113 can be designed to be smaller; the upper and lower sides 110 of the aluminum profile body 11 bear the shearing force transmitted from the second side 112 and the inner side 113, so the wall thickness value thereof needs to be designed to be larger. In conclusion, the utility model discloses according to the difference of each limit atress condition of aluminium alloy body 11, design the thickness value of first side 111 for the biggest, the thickness value of upper and lower both sides 110 is inferior, and the thickness value of second side 112 and interior limit 113 is less to further optimize aluminium alloy body 11 structure, solved the low, the not high problem of lightweight level of material utilization rate that brings with the wall thickness design.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
