Description
Technical Field
The invention relates to a supporting rod for a blind-repairing mirror of a truck, and belongs to the field of automobile parts.
Background
When a person drives a car, the person sits in a closed space, the visual field is blocked, and the car rearview mirror is needed to enlarge the visual field range, but for a truck, a single rearview mirror does not meet the visual field requirement, for example, the height of the cab of the truck is relatively high, the driver can hardly see the lower right side of the cab directly, the area becomes a visual blind area, the danger is easy to form, and a blind supplementing mirror is needed to be additionally arranged on the truck.
At present, the blind-repairing mirror support rod on the market is a straight rod or a bent rod, the thickness of each part of the blind-repairing mirror support rod is consistent, but the blind-repairing mirror support rod is driven by traction force provided by a vehicle body, the load born by the blind-repairing mirror support rod is changed from large to small from one side close to the vehicle body to one side far away from the vehicle body, so that the blind-repairing mirror support rod which is close to the vehicle body is easy to cause a fracture phenomenon, the whole thickness of the straight rod or the bent rod type blind-repairing mirror support rod is improved for solving the problem, but the corresponding problem is also correspondingly generated, namely, the weight of the blind-repairing mirror support rod is increased to cause the whole weight of a truck to be increased, and meanwhile, the blind-repairing mirror support rod generates larger force at the joint of the vehicle body and the blind-repairing mirror support rod is easy to cause the problem of bolt fracture.
Disclosure of Invention
In order to solve the technical problems in the prior art, the invention provides the truck blindfold mirror support rod which is an airfoil with the cross section area changed from one side close to a vehicle body to one side far away from the vehicle body from large to small in sequence, so that the problem of fracture caused by different loads born by all parts of the blindfold mirror support rod is solved, and meanwhile, the weight of the blindfold mirror support rod is reduced.
The technical scheme for achieving the purpose is that the support rod of the truck blind-repairing mirror at least comprises a support rod connected with a mirror body, one end of the support rod is provided with a support seat attached to a car body, the support rod is an airfoil, the included angle between the front edge of the support rod and the support seat is smaller than the included angle between the rear edge of the support rod and the support seat, the area of one side, connected with the support seat, of the support rod is larger than the area of the opposite side of the support seat, a bent rod is arranged on the opposite side of the support rod, the end part of the bent rod is connected with a ball, the bent surface of the bent rod is provided with a reinforcing rib A attached to the bent surface and the upper surface of the support rod at the same time, the lower layer of the support rod is of an open box structure, the box body is internally provided with an inner surface connected with the front edge and the rear edge, and the inner surface of the reinforcing rib B is simultaneously covered at the joint of the reinforcing rib A and the support rod, the distance between the reinforcing rib C and the rear edge of the support rod is gradually increased along with the distance close to the support seat, and a through hole perpendicular to the car body is arranged on the support seat.
The technical scheme is further improved as follows: the material of the supporting rod is die-casting aluminum alloy.
And the material of the strut is YL113.
And the included angle between the front edge of the supporting rod and the supporting seat is 36 degrees.
And the included angle between the rear edge of the supporting rod and the supporting seat is 28 degrees.
And the front edge of the supporting rod is arc-shaped.
And a reinforcing rib is arranged between the reinforcing rib C and the front edge of the support rod and between the reinforcing rib C and the rear edge of the support rod.
And the support rod is substantially integrated with the support.
The technical scheme can be seen that: the truck blindfold mirror support rod provided by the invention is an airfoil with the cross section area which is sequentially changed from the side close to the vehicle body to the side far from the vehicle body, and the mechanism meets the requirements of different thicknesses required by the load which is sequentially changed from the side close to the vehicle body to the side far from the vehicle body and is born by the truck blindfold mirror support rod;
the support is not directly connected with the vehicle body, but is connected with the support by attaching to the vehicle body, and the contact area of the support and the vehicle body is larger than that of the support, so that the load born by each part of the support is smaller than that of the joint of the support and the vehicle body of the existing blind-repairing mirror;
meanwhile, the included angle between the front edge of the support rod and the support seat is smaller than the included angle between the rear edge of the support rod and the support seat, so that one side far away from the vehicle body is closer to one point of the vehicle body compared with the support rod vertical to the vehicle body, the vehicle width is reduced, and meanwhile, as the airflow velocity component vertical to the front edge of the support rod is lower than the running velocity, compression waves can only appear under the condition of higher running velocity compared with the support rod vertical to the vehicle body;
and through designing the branch to the lower floor be open-ended box body structure, can reduce the weight of branch by a wide margin to reduce the power that branch and support received, reduce the whole car weight simultaneously.
The angle of the truck blind-repairing mirror can be adjusted at any time by arranging the round ball to be connected with the truck blind-repairing mirror, and the area of the connecting part is increased by adding the bent rod between the round ball and the supporting rod, so that the round ball is not easy to fall off; and meanwhile, a reinforcing rib A which is simultaneously attached to the bending surface and the upper surface of the supporting rod and a reinforcing rib B which covers the joint of the reinforcing rib A and the supporting rod are arranged to increase the thickness of the bending rod and the joint of the bending rod and the supporting rod.
