Technical Field

The invention relates to the technical field of electric automobiles, in particular to a mounting structure of a sunshade assembly on automobile roof glass.

Background

With the rapid development of economy and the continuous enhancement of environmental awareness of people, electric vehicles using lithium batteries are rapidly popularized.

It is known that for a car, the height space (i.e. the dimension in the Z direction) inside the car is very important, and increasing the dimension in the Z direction can improve the comfort of the driver and passengers, but at the same time, the wind resistance of the car during running can be increased, and the larger dimension in the Z direction is usually set only on luxury car models.

And along with the development of intelligent driving technique, the integrated laser radar module in automobile body roof front end becomes a development direction, and correspondingly, more cameras and radar products will be integrated to the head of front row position in the car, consequently, can occupy valuable head space in the car (Z is to the size promptly).

In addition, the existing car is generally provided with a panoramic skylight so as to be convenient for better illumination, meanwhile, a sunshade curtain comprising a retractable motor is arranged on the skylight so as to prevent burning sun in summer from directly irradiating passengers in the car, and the retractable motor is arranged at the upper right of the main driving and is overlapped with the installation position of the laser radar up and down, so that the Z-direction size at the position is more narrow.

In the prior art, the installation structure of the panoramic sunroof and the sunshade assembly is generally: the sun-shading curtain assembly is fixed on the skylight reinforcing plate, and the skylight reinforcing plate is fixedly connected with the side wall inner plate, so that the distance from the curtain cloth in the sun-shading curtain assembly to the inner surface of the skylight glass is larger, and the effective Z-direction size of the space in the automobile is reduced on the premise of the same height of the whole automobile.

Disclosure of Invention

The invention aims to provide a mounting structure of a sunshade assembly on automobile roof glass, which can reduce the Z-direction dimension of the roof at the upper right of a driver to the maximum extent on the premise of ensuring the normal use of the sunshade, further ensure that the interior of an automobile body has enough space in the automobile and improve the comfort level of the driver and passengers during riding.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a sunshade screen assembly mounting structure on car roof glass, is equipped with the skylight glass who concreties with the side wall including setting up at the panorama skylight hole at automobile body top, the side wall that is located panorama skylight hole left and right sides, in panorama skylight hole in be equipped with the sunshade screen assembly with the side wall, be equipped with the sunshade screen assembly in skylight glass's below, the sunshade screen assembly includes sunshade screen guide rail, sunshade screen cloth, is used for receiving and releasing the driving motor of curtain cloth, and it bordures to form PU through injection moulding technology in skylight glass inboard, bordures at PU and embeds to be equipped with embedded nut, be equipped with the fastening screw with embedded nut threaded connection on the sunshade screen guide rail.

Firstly, the skylight glass is arranged on the automobile top cover and connected with the side wall of the top of the automobile body, so that the fixed panoramic skylight is formed. Particularly, the sunshade curtain guide rail in the sunshade curtain assembly is directly fixed on the skylight glass, so that the distance between the sunshade curtain cloth and the skylight glass can be greatly reduced, the space size of the interior of the vehicle body in the Z direction can be increased on the premise of keeping the height of the vehicle body unchanged, and the comfort level of drivers and passengers in the vehicle during riding is improved.

It should be noted that the injection molding process of the PU material is a prior art, and the invention creatively applies the prior art to the installation structure of the sunshade screen assembly, so that the embedded nut for fixedly connecting the sunshade screen assembly is embedded in the PU wrapping edge integrally connected with the window glass as an embedded piece during injection molding, thereby facilitating the fixation and installation of the sunshade screen assembly and directly forming the embedded nut on the skylight glass.

Preferably, the distance between the curtain cloth and the inner side face of the skylight glass is 20mm-30 mm.

It is known that in the prior art, because the sunshade curtain guide rail is usually fixed on the side wall inner plate through the skylight reinforcing plate, the distance between the curtain cloth and the inner side surface of the skylight glass is usually between 40mm and 50mm, and the invention creatively fixes the sunshade curtain guide rail on the skylight glass directly through the PU wrapping, so that the distance between the curtain cloth and the inner side surface of the skylight glass can be reduced to between 20mm and 30mm, and the Z-direction size of the panoramic skylight can be reduced to the maximum extent on the premise of not increasing the complexity of the assembly process.

As preferred, bordure at PU and embed and be equipped with the location strip, be equipped with the step face of hexagon in buried nut one end in advance, be equipped with on the location strip with the hexagonal mounting hole of step face adaptation and be used for main locating hole and the vice locating hole of location, the injection moulding that PU bordures includes following step:

a. placing the embedded nut into the mounting hole of the positioning strip, and enabling the step surface of the embedded nut to be matched in the mounting hole;

b. the positioning strip with the embedded nuts is placed into a die for forming the PU wrapping edges, the positioning pins on the die are respectively inserted into the main positioning holes and the auxiliary positioning holes on the positioning strip, so that the positioning strip is positioned, skylight glass is attached to the die through the glass edge and the curved surface, the PU wrapping edges are formed through injection molding, and the embedded nuts, the positioning strip and the glass can be formed into a whole.

Therefore, the invention has the following beneficial effects: under the premise of ensuring the normal use of the sun-shading curtain, the Z-direction size of the roof at the upper right part of the main driving can be reduced to the maximum extent, so that the sufficient space in the vehicle body is ensured, and the comfort level of drivers and passengers in riding is improved.
