Description

Skylight wind-guiding net anti-pinch structure
Technical Field
The utility model belongs to the technical field of reliability and durability of vehicle parts, and particularly relates to an anti-clamping structure of a skylight air guide net.
Background
With the development of the automobile industry, the functions carried by the automobile are more and more, and people gradually pay attention to multiple attributes such as safety, comfort, convenience, science and technology besides the original functions of the automobile. The application of skylights, especially panoramic skylights, greatly expands the field of view of the vehicle and brings about better ventilation effects, and is therefore becoming more and more favored by consumers. In the running process of the automobile, the wind speed is high, and when the automobile skylight is opened, large noise is often easy to generate, so that the wind-guiding net device is arranged on the automobile skylight, and the noise is reduced when the automobile skylight is opened. The main structure of the skylight wind-guiding net is soft cloth, the skylight is compressed and folded back into the skylight in the closing process of the skylight, in the process, if the wind-guiding net is folded reversely, the wind-guiding net is easily clamped between the skylight glass and the skylight external sealing strip, and once the outside has a rainwater environment, the wind-guiding net can introduce the outside rainwater into the vehicle, so that water leakage in the vehicle is caused.
In the prior art, a plurality of soft adhesive tapes are often stuck at the corner positions of the air guide net, so that the purpose is to play a role in guiding in the folding process of the air guide net, but the structure is positioned at the corner positions of the two sides of the air guide net, the effect is limited for the air guide net with a longer overall size, and some air guide nets do not have corner structures, so that the adhesive tapes cannot be stuck, and the risk of water leakage is still large.
The prior art discloses a PU is bordured for car seal, including PU package Bian Benti, its characteristics are that there is the boss in PU body outside edge of borduring, form new PU structure of borduring through the boss that extends certain height in the outside of PU body of borduring, no longer need extra double faced adhesive tape and EPDM gasket member and connect the installation step like this. However, the special PU edge is used for replacing the EPDM gasket to compensate micro deformation of PU under the pressure of glass and other parts or better guide the positioning of the glass and other parts, and the PU edge is subject to the pressure of the glass and other parts, and the structure cannot play a role in preventing the wind-guiding net from being clamped.
The prior art also discloses a car sunroof wind screen fold-preventing structure, which comprises a base and a wind screen, wherein the bottom of the wind screen is connected with the base, the top of the wind screen is connected with a wind screen beam, soft plastic coated ribs are arranged on two sides and four corners of the wind screen beam, and the plastic coated ribs and the wind screen are integrally formed by injection molding. The wind screen is fixed up and down through the mounting plate and the pressing strip, and two sides are wrapped through plastic coated rib modeling, so that appearance defects such as flash are avoided, and an important supporting effect is achieved on the corner structure of the wind screen. However, the fold-preventing structure is arranged at the corner positions on two sides of the air guide net, and is formed by integrally injection molding the soft plastic coated ribs and the air guide net, so that the structure cannot be suitable for the air guide net without corners.
In summary, most of the mentioned anti-clamping structures of the air guiding net in the prior art are integrally injection-molded or adhered to corner positions on two sides of the air guiding net by using soft adhesive tapes, and the structure cannot prevent the anti-clamping of the middle position of the air guiding net and cannot be suitable for the type of the air guiding net without the corner structure.

The anti-clamping structure of the air guide net of the skylight comprises a folding guide mechanism (shown in rectangular frames in fig. 1 and 3) so as to ensure that the air guide net falls below the sealing position of the skylight glass and the external sealing strip of the skylight glass before the skylight glass is completely closed, and plays a role in preventing clamping.
As shown in fig. 1, a relatively closed space is formed among the vehicle body top cover 1, the sunroof outer weather strip 2, the sunroof front glass 4, the front glass PU cladding 3 and the sunroof front beam 5, and the folding guide mechanism is arranged in the space.
In one embodiment of the present utility model, the folding guide mechanism is disposed on the front glass PU edge 3 of the front glass 4 of the sunroof, and may specifically be a front side of the front glass PU edge 3.
The folding guide mechanism is usually a single soft entity, and is adhered or clamped on the front glass PU wrapping edge 3 in the X direction and the Y direction from the Y0 position to the protruding structures of the two sides of the skylight.
In the process of closing the skylight, the folding guide mechanism moves together with the front skylight glass 4 and the air guide net 6, and gradually contacts with the air guide net 6 in the folding process of the air guide net 6 along with the descending of the front skylight glass 4, so that the air guide net 6 is limited, the folding effect of the air guide net 6 is limited, and the anti-clamping effect is achieved.
In one embodiment of the utility model, the folding guide mechanism and the front glass PU wrapping 3 are integrally formed.
The folding guide mechanism is not limited to materials, mounting means and molding conditions. As shown in fig. 2, the folding guide mechanism is designed with consideration given to: the opening dimension L of the air guide net and the folding dimension L' of the air guide net are equal to the folding points A-F of the air guide net. It is assumed that after the front window glass 4 is closed, the air guide net 6 is just clamped between the exterior weather strip 2 of the window and the PU cladding 3 of the front window glass, this state being the limit state in which the air guide net 6 is clamped. The overall dimensions of the air guiding net 6 in this fairly closed space are calculated as L' =ab+bc+2, cd+ce+ef. Under the action of the folding guide mechanism, if the designed size of the folding guide mechanism can ensure that L is smaller than L', the air guide net 6 cannot be clamped in the folding process.
As shown in fig. 3, the folding guide mechanism is designed on the front glass PU wrapping edge 3, and gradually reduces from the middle to two sides so as to avoid the movement track of the front glass 4 of the skylight, and interference is prevented. The structure should consider simultaneously and dodge wind-guiding net skeleton motion track in the skylight closing process, prevents to interfere.
In one embodiment of the present utility model, the folding guide mechanism material is PU (polyurethane) material.
The anti-pinch structure is connected, preferably, is designed as a whole with the front glass PU wrapping 3, and is subjected to integral injection molding;
as described above, the folding guide mechanism is designed on the front glass PU edge 3, and L < L' is ensured, so that in the closing process of the front glass 4 of the skylight, the folding guide mechanism moves along with the front glass PU edge 3, and meanwhile, along with the folding process of the air guide net 6, the anti-clamping structure limits the air guide net 6, so that the air guide net 6 is ensured not to be clamped in the folding process, and the problem of water leakage in the vehicle caused by clamping of the air guide net 6 is avoided.
