Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is specifically described.
Specific embodiment 1: as shown in Figure 1, Figure 2, Figure 3 shows.Sunshade device for automobile, comprises roof 1, the parallel placement of Windshield 2, first base bar 3, second base bar 4, first base bar 3, second base bar 4, and the first base bar 3, second base bar 4 is fixed on below in roof 1.Be provided with gap between first base bar 3, second base bar 4 and roof 1, the front end of the first base bar 3, the front end of the second base bar 4 are close to the upper limb of Windshield 2.First base bar 3, second base bar 4 is corresponding chute 301, the chute 302 be provided with for corresponding placement first extension bar 5, second extension bar 6 respectively.First extension bar 5, second extension bar 6 is made for elastomeric, deformable material; First extension bar 5, second extension bar 6 correspondingly can stretch out from the front end of the first base bar 3, second base bar 4 respectively.
The front portion of that one end that the first extension bar 5 stretches out outside the first base bar 3 is provided with the first roller 7, after first roller 7 contacts the inner face of Windshield 2, first extension bar 5 is more to protracting, first roller 7 is subject to the resistance of Windshield 2 inner face, first extension bar 5 starts elastic deformation, and the front portion of the first extension bar 5 can reach the lower edge of Windshield 2.
The front portion of that one end that the second extension bar 6 stretches out outside the second base bar 4 is provided with the second roller 8, after second roller 8 contacts the inner face of Windshield 2, second extension bar 6 is more to protracting, second roller 7 is subject to the resistance of Windshield 2 inner face, second extension bar 6 starts elastic deformation, and the front portion of the second extension bar 6 can reach the lower edge of Windshield 2.
Front bar 9 one end is connected to the front portion that the first extension bar 5 stretches out that one end outside the first base bar 3, and the front bar other end is connected to the front portion that the second extension bar 6 stretches out that one end outside the second base bar 4.
Rolling roller 10 two ends are arranged at the front end of the first base bar 3, the front end of the second base bar 4 respectively, and rolling roller 10 is positioned on the first base bar 3, second base bar 4, and in space between the first base bar 3, second base bar 4 and roof 1.The two ends of spool 11 of automatic winding can be arranged at the rear end of the first base bar 3, the rear end of the second base bar 4 respectively, spool 11 is positioned on the first base bar 3, second base bar 4, and in space between the first base bar 3, second base bar 4 and roof 1; The wind spring that can make spool 11 automatic winding is provided with in spool 11.
Puggaree 12 front end is connected with front bar 9, and the rear end of puggaree 12 is connected with spool 11, walks around rolling roller 10 in the middle part of puggaree 12.When the front portion of the first extension bar 5, the front portion of the second extension bar 6 can reach the lower edge of Windshield 2, puggaree 12 can cover Windshield.
Also comprise the transmission device making the first extension bar 5, second extension bar 6 motion.
Transmission device comprises screw mandrel 13, motion sheet 14, motor 15, and machine shaft is connected with screw mandrel 13, and motion sheet 14 is provided with screw hole, and screw hole is threaded with screw mandrel 13; Motion sheet 14 is connected with the rear end of the first extension bar 5 or the rear end of the second extension bar 6.In this example, motion sheet 14 is connected with the extension 51 of the rear end of the first extension bar 5.
First extension bar 5, second extension bar 6 is made up of elastic plastic material.
Motor 15 is fixed on corresponding first base bar 3, and can certainly select to be fixed on the second base bar 4, other parts are adjusted accordingly.
Principle of work: transmission device generation action, makes the first extension bar, the second extension bar stretches out forward, drives puggaree to travel forward simultaneously.After first roller, the second roller are subject to the stop of Windshield inner face, first extension bar, the second extension bar start distortion, degree of dip along Windshield is out of shape, when the front portion of the first extension bar 5, the front portion of the second extension bar 6 can reach the lower edge of Windshield 2, puggaree 12 can cover Windshield.So just achieve a sunshade action, convenient, simple to operate, puggaree and Windshield paste closer.When going sunshade, the first extension bar, the second extension bar are return in the first base bar, the second base bar, and spool is under the effect of inner wind spring, and automatic winding, the rear end of puggaree is rolled up on spool.
Structure of the present invention is simple, and space used is little, and setting position is reasonable.Change little to bassinet structure.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
