The disclosed sealing band of above-mentioned patent documentation has sealing property preferably, but, after the long-time use of above-mentioned sealing band at that time, sponge foaming part (or foaming part) can deform or come off, and sealing property will decrease.
The utility model content
The utility model provides a kind of weather strip for automobile, and the sealing bar is simple in structure, after long-term the use, not yielding, good sealing effect.
A kind of weather strip for automobile, the elastic seal section that comprises the holding part mutually engaged with Metal Sheets for Body-manufacturing and be fixed on described holding part top, be provided with cavity in described elastic seal section, cavity has the vent that is positioned at described elastic seal section outer wall, in described cavity, is provided with support bar; Described holding part is connected by the connecting portion of hollow structure with elastic seal section.
The utility model adopts support bar is set in elastic sealing strip, and when elastic seal section is extruded, support portion is supported elastic sealing strip, when strengthening leak tightness, prevents that elastic seal section from deforming.
Described support bar can be selected multiple material, and when support bar is homogenous material, as preferably, described support bar is the cylindrical rubber bar.Described support bar also can be selected double-decker, and described double-decker comprises the inner metal-cored rubber layer with being wrapped in metal-cored outer wall.
For ease of the installation of holding part, as preferably, described holding part is inverted U, and described holding part inwall is provided with some card bases, in described holding part, is provided with packing seal.The general paired setting of some card bases, apply certain Clamping force to vehicle body sheet metal, prevents that sealing band from coming off.Card base operated by rotary motion 2-3 couple, and end all curves inwardly.
For further improving the Joint strenght between holding part and Metal Sheets for Body-manufacturing, as preferably, described packing seal is provided with buckling groove, for the engaging of Metal Sheets for Body-manufacturing.Packing seal can adopt the elastomeric material elastomeric material.
The EPDM dense layer that described holding part comprises the rolling steel band of inverted U and is coated on the rolling steel band outer wall of described inverted U.The elasticity of rolling steel band and moulding are all better, have greatly increased the service life of sealing band of the present utility model.
Described holding part both sides are respectively equipped with outer gland sealing pin and inside lap pin.The outer gland sealing pin, for contacting with the sealing of body exterior sheet metal component, prevents that rainwater into the car.The inside lap pin, for overlapping with the vehicle body trim panel, further increases the overall tightness of vehicle body.
Described holding part bottom is provided with the auxiliary seal pin be wholely set with described outer gland sealing pin, and described auxiliary seal instep arranges to described outer gland sealing pin.The Metal Sheets for Body-manufacturing that the auxiliary seal pin strengthens on the one hand and the Clamping force of sealing band, also further avoided entering of rainwater on the other hand.
Described elastic seal section comprises that EPDM dense layer and painting are located at the organic silicon coating of EPDM dense layer outer wall.With the EPDM sponge, compare, the EPDM dense layer all has more good elastic performance, and has self-healing preferably.
Compared with prior art, the beneficial effects of the utility model are embodied in:
Weather strip for automobile of the present utility model, integral structure is simple, and after long-term the use, not yielding, good sealing effect, can effectively prevent that rainwater is into the car; Simultaneously, can save the installation bump rubber, cost-saving, practicality is stronger.
