The utility model discloses have very high rigidity and intensity, can improve the connection and the separating speed of connecting rod and automobile body greatly to the maintenance of greatly reduced vehicle is loaded down with trivial details and the difficulty degree.
Description
Technical Field
The utility model relates to an electric automobile technical field, concretely relates to connection structure of battery package and sub vehicle frame.
Background
The connection position of the connecting rod and the auxiliary frame is positioned below the auxiliary frame, and the connection position of the connecting rod and the vehicle body is positioned below the power battery and is characterized in that the connection position is horizontally oriented. This link is now an L-shaped one-piece construction as shown in fig. 1 and must generally be removed before the subframe, or other component mounted thereon, can be replaced or repaired. The connecting rod is of an integrated structure, one end of the connecting rod connected with the vehicle body is located below the power battery, and the power battery connecting the connecting rod and the vehicle body needs to be loosened and taken away when the connecting rod is separated from the vehicle body, so that the power battery needs to be disassembled first, and the connecting rod cannot be separated from the vehicle body due to the problem of operation space, and as a result, the vehicle is very complicated and difficult to maintain. The chinese invention patent documents entitled "rear suspension and vehicle body of electric vehicle" and the application No. 201410441156.3, No. CN 105365543B relate to the problem of mounting and connecting the battery pack, but only the mounting position of the battery pack is described. No particular structural problems of the connecting rod are involved.
Disclosure of Invention
The main object of the present invention is to provide a connecting rod structure for a vehicle, which can greatly reduce the complexity and difficulty of vehicle maintenance.
The utility model discloses used technical scheme is: a connecting rod structure comprises a connecting rod main body and a switching bracket. One end of the connecting rod main body, which is far away from the auxiliary frame, is provided with two through holes for passing through bolts connected with the switching bracket through the bolts; the switching support includes connecting rod main part connecting portion, automobile body connecting portion. The connecting rod body connecting part is perpendicular to the vehicle body connecting part. The one end that sub vehicle frame was kept away from to connecting rod main part connecting portion and connecting rod main part is removable linking firmly with two bolts, and the automobile body connecting portion is removable linking firmly with the automobile body with two bolts.
Here automobile body connecting portion still links to each other through the bolt and the automobile body of horizontal trend like original integral type connecting rod, but connecting rod main part connecting portion then links to each other through the bolt and the connecting rod main part of vertical trend, can keep power battery motionless like this, just can separate connecting rod main part connecting portion and connecting rod main part mutually to greatly reduced the maintenance of vehicle loaded down with trivial details and the degree of difficulty.
Preferably, the link body includes a link body upper layer, a link body middle layer, and a link body lower layer. The upper layer of the connecting rod main body and the lower layer of the connecting rod main body are flat plate parts. The middle layer of the connecting rod main body is formed by continuously bending a flat plate and comprises an upper horizontal flat plate part, a lower horizontal flat plate part and three mutually parallel vertical flat plate parts; the upper end parts of the upper layer and the middle layer of the connecting rod main body are welded, and the lower end parts of the lower layer and the middle layer of the connecting rod main body are welded. In the preferred embodiment, the connecting rod main body having high strength and high rigidity can be obtained with a small material consumption. Further preferably, the upper layer of the connecting rod main body is provided with an upward bulge to further improve the rigidity and the strength.
Preferably, one of the two through holes provided in the vehicle body connecting portion for the corresponding bolt to pass through is a long hole. This preferred scheme is favorable to reducing switching support processing manufacturing cost, improves the installation connecting speed of switching support and automobile body.
To sum up, the beneficial effects of the utility model are that: the connecting rod has high rigidity and strength, and can greatly improve the connecting and separating speed of the connecting rod and the vehicle body, thereby greatly reducing the complexity and difficulty in vehicle maintenance.
