the utility model provides a vehicle stand handrail mounting structure, includes the stand and sets up in the spacing base of automobile body floor upper surface, the top of spacing base is equipped with vertical spacing hole, the upper end and the automobile body top fixed connection of stand, the lower extreme of stand insert spacing downthehole and with spacing hole the hole bottom have the interval.
Therefore, only the upper end of the upright column is fixed with the top of the vehicle body, and the upright column is not connected with the floor of the vehicle body and can move up and down in the limiting hole, so that the connection between the top of the vehicle body and the floor of the vehicle body is broken, the upright column connecting area of the vehicle body is not affected by the deflection change of the floor of the vehicle body, and the damage caused by the deflection change of the floor of the vehicle body is avoided. When the passenger grasps the upright post, more in order to offset inertia generated by speed change in the vehicle running process, more horizontal force is applied to the upright post, and therefore the horizontal degree of freedom at the lower end of the upright post is limited through the limiting base, so that the passenger can stand stably when grasping the upright post. The lower extreme of stand and the hole bottom in spacing hole have the interval for the stand is unlikely to contact at vertical direction with spacing base when reciprocating.
Specifically, spacing base includes fixing base and spacing housing, the lower extreme of fixing base passes through bolted connection automobile body floor, and spacing housing overlaps in the fixing base outside and is connected with the fixing base through the bolt, the upper end of spacing housing is located to spacing hole. Through the fixed spacing housing of fixing base, the horizontal degree of freedom of the spacing housing restriction stand lower extreme of rethread, convenient to operate's spacing housing can also shelter from the fixing base in the time, makes spacing base more pleasing to the eye.
Specifically, the upper end of stand is equipped with the stand connector, and the top of stand connector is connected with T type bolt, the head card of T type bolt is in the die cavity of automobile body back timber.
Specifically, the upper end of stand connector has the horizontally connecting plate, the surface of connecting plate is equipped with vertical connecting hole, the lower extreme of T type bolt inserts in this connecting hole and fastens through the nut.
In order to avoid the rotation of the upright post connector in the horizontal direction, the number of the connecting holes is at least two, and each connecting hole is correspondingly connected with one T-shaped bolt.
In order to shield the connecting area component and keep the appearance attractive, the outer side of the upright post connector is sleeved with a top outer cover.
In order to avoid the mutual extrusion of the contact surface of stand and spacing hole to cause interface deformation, wearing and tearing, production abnormal sound, the inner wall surface laminating in spacing hole is provided with elastic lining. The elastic lining can play the roles of buffering and filling, and the stand column and the limiting hole are prevented from being extruded mutually.
In order to avoid the vertical column from being taken out of the limiting hole when moving up and down, a horizontal groove is formed in the surface of the inner wall of the limiting hole, a flange matched with the groove is arranged on the outer surface of the elastic lining, and the flange is embedded into the groove. Therefore, the elastic lining is clamped at the position of the groove by the flange, and the vertical freedom degree of the elastic lining is limited.
The utility model discloses the beneficial effect who possesses: the utility model discloses a vehicle stand handrail mounting structure only fixes the upper end and the automobile body top of stand, makes the stand linking area of automobile body not receive the influence that the automobile body floor amount of deflection changes to consequently the damage that causes has been avoided. The structure is simple, the installation is convenient, and the installation problem of the upright post handrail is solved while the production error of the upright post in the height direction of the vehicle is solved.
