Description

A self-locking windscreen with low wind noise

technical field

The invention belongs to the field of panoramic sunroofs, and in particular relates to a low-wind-noise self-locking wind-shielding net for sunroofs to shield the wind.

Background technique

At present, the components of automobile roof sunroof usually include frame, sunshade, glass, wind guide net and so on. The wind guide net is mainly used to divert the airflow flowing through the windscreen to the top or both sides of it, so as to prevent the airflow from blowing directly to the passengers, and at the same time reduce the noise caused by the airflow and improve the comfort of the ride.

The existing skylight wind guide net structure still uses torsion springs to elastically support or contract the upper and lower skeletons of the wind guide net, and the torsion springs abut on the skylight track. , The shrinkage offset causes the opening and closing of the air guide net to be stuck, and there are abnormal noises and life effects.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned problems in the use of the wind guide net, the present invention provides a low wind noise self-locking wind shield net with a compact, stable and firm structure, which is elastically opened and contracted without jamming and abnormal noise.

The technical scheme adopted in the present invention is: a low-wind-noise self-locking wind-shielding net, comprising upper and lower frames, mesh cloth and a mounting seat, the lower frame is installed at the front end of the skylight track seat, and the front end of the upper frame and the frame of the lower frame are pulled between the frames. The mesh cloth is connected, and the feet on both sides of the rear end of the upper frame are respectively connected to the two sides of the skylight track seat through two mounting seats. The rear part of the mounting seat is provided with a pivot seat, the pivot seat is pivotally connected with the end of the rear end side foot of the upper frame, the middle part of the mounting seat is provided with a spring limit bayonet for the front and rear side limits, and the front part of the mounting seat is provided with a spring foot bayonet, a The torsion spring is connected with the upper frame and the mounting seat. The torsion spring includes a middle elastic part and upper and lower spring feet. The middle elastic part is placed in the spring limit bayonet; The spring foot is placed in the spring foot bayonet.

Further, the spring limit bayonet is formed by the limit stops disposed on the front side and the rear side of the middle part of the mounting seat and spaced apart from the bayonet position.

Further, the front end of the lower spring foot is provided with a bent portion that is folded back toward the middle elastic portion, and the spring foot bayonet is fitted with a front and rear clip on the mounting seat to form a circular arc void. The gear is formed, and the elbow is clamped into the arc neutral.

Further, the upper gear opening of the arc neutral gear is slightly contracted inward to form a stopper for engaging with the bent head of the lower spring foot.

Further, a lower spring foot limit stop is arranged between the spring foot bayonet of the mounting seat and the spring limit bayonet, and the lower spring foot limit stop is arranged on the front side and/or the rear side of the mounting seat.

Further, an upper spring foot limit block is arranged in the middle and rear part of the rear end side foot of the upper frame, and the upper spring foot limit block is arranged on the front side and/or the rear side of the rear end side foot of the upper frame.

The torsion spring of the present invention is installed on the skylight track by a mounting seat, and the upper spring foot of the torsion spring is limitedly attached to the lateral limit of the rear end side foot of the upper frame through the upper spring foot limit stop, and is hooked by the hook at the front end of the torsion spring. Pull into the waist-shaped groove, the middle elastic part of the torsion spring is clamped between the front and rear limit blocks of the mounting seat, the middle and front part of the torsion spring is laterally limited by the lower spring foot limit block, and the torsion spring The bent head of the front end of the lower spring foot is clamped into the stop of the arc neutral position, and the upper, middle and lower parts of the torsion spring are limited and clamped, which can effectively ensure the stable and firm installation of the torsion spring. Under the working environment of repeated torque action, it can ensure that there is no hidden danger of deviation, no jamming, and no abnormal noise, which is conducive to ensuring safe use.
