Abstract
The utility model provides an automobile vacuum boosting bag. The automobile vacuum boosting bag comprises a vacuum cavity formed by butt joint of an upper shell and a lower shell, an exhaust pipe communicated with the cavity and a bracket horizontally surrounding in the middle of the cavity, middles of the upper shell and the lower shell recess oppositely, a support for mounting of an alarm sensor is arranged on the side wall of the cavity, and strip reinforcing ribs are arranged on the outer wall of the cavity. The automobile vacuum boosting bag is characterized in that recesses of the upper shell and the lower shell are in butt joint, and the cross section of the cavity is circular. Since the cross section of the cavity is circular, forming is easy, formability of plastic parts is improved, flowing of airflow is facilitated during vacuumizing, degree of vacuum is high, internal stress is eliminated, product service life is long, and working performance is excellent.
Description
Technical field
The utility model provides a kind of vacuum automobile power-assisted bag, belongs to the vehicular spare parts technical field.
Background technology
Existing vacuum automobile power-assisted bag, mostly its cavity cross-sectional plane is square, and mould molding is complicated, and when vacuumizing, large, the low vacuum of air current flow resistance, make the brake power-assisted be obstructed; And stress is large, easily distortion, and the life-span is low.
The utility model content
The purpose of this utility model be to provide a kind of can overcome defects, air current flow smoothly, can improve the vacuum automobile power-assisted bag that in-use performance can improve again forming characteristics.Its technical scheme is:
A kind of vacuum automobile power-assisted bag, comprise vacuum cavity, the freeing pipe that is communicated with cavity and the horizontal circle carriage in the middle part of cavity that is consisted of by upper shell and lower house docking, cave in opposite directions in the middle part of upper shell and lower house, the sidewall of cavity is provided with the bearing that warning sensor is installed, the outer wall of cavity is provided with the bar shaped reinforced rib, it is characterized in that: the middle part docking of upper shell and lower house depression, the cross-sectional plane of cavity is annular arrangement.
Described vacuum automobile power-assisted bag, it is radial that reinforced rib is, and is distributed on chamber outer wall.
Described vacuum automobile power-assisted bag, outside in internal diameter is gradually little for the depression in the middle part of upper shell and lower house.
The utility model compared with prior art, its advantage is:
1, the cross-sectional plane due to cavity is annular arrangement, is easy to moulding, has improved the forming characteristics of plastic;
2, the cross-sectional plane due to cavity is annular arrangement, is convenient to air current flow when vacuumizing, and degree of vacuum is high;
3, eliminated internal stress, long product lifecycle.
