Description

Car sunshade

Technical field

The present invention relates to a kind of Automobile Products more particularly to a kind of car sunshades.

Background technique

It is stagnant due to the construction of corresponding auxiliary facility as the improvement of people's living standards, the quantity of private car is growing day by day Afterwards, most vehicles are parked to be outdoor, and irradiation of the summer vehicle by the sun, interior temperature can be increased sharply such as food steamer one As, It is sultry and stifling, feeling is felt bad very much.Vehicle is exposed to the sun for a long time simultaneously drenches with rain and accelerates the aging of vehicle paint.Affect vehicle Riding experience shortens the service life of vehicle.

Summary of the invention

The present invention is directed to be directed to background technique, a kind of simple and easy-to-use car sunshade is provided, is prevented Burning sun is exposed to the sun to automobile, improves and drives comfort level.

The technical solution that the present invention uses is: a kind of car sunshade, including flexible skeleton and driving device, described flexible Skeleton is to form the fenestral fabric of at least four main national highways in China, infall is by even by the cross link in length and breadth of series connection scissor-type mechanism Fitting connection;The series connection scissor-type mechanism is made of several scissor-type linkage unit head and the tail hinged in series;The driving dress Set includes motor and open-and-close mechanism;The open-and-close mechanism includes four nut sliders that can do opening and closing movement;It is described to stretch Contracting skeleton is fixedly connected with four nut sliders of the open-and-close mechanism, under motor driven, four slide nuts of open-and-close mechanism Block does opening and closing movement, to drive flexible skeleton expansion or shrink.

The scissor-type linkage unit is hingedly made of outside connecting rod and inner link scissor-type.

The open-and-close mechanism is made of screw rod, fixing bearing, bevel gear and nut slider, and four have nut slider Screw rod is perpendicularly fixed on pedestal two-by-two by fixing bearing, wherein the end of three screw rods being located at base center is fixed with cone Gear simultaneously engages, the end of another screw rod being located at base center with and its screw rod for being located at same linear position end It is coupled by shaft coupling;A screw rod therein and nut slider thereon design for left-hand thread, remaining three screw rod and thereon Nut slider designs for right-hand thread, motor driven left-hand thread screw rod forward or reverse, drive nut slider on four screw rods synchronous to It is interior or be displaced outwardly.

Design is scientific and reasonable for structure of the invention, small in size, light-weight after storage, at low cost, operates and easy for assemble or unload, Flexibility is strong, is not limited by regional condition, does not influence the normal use of vehicle.

Specific embodiment:

Below in conjunction with attached drawing, the invention will be further described.

As shown in Figure 1, a kind of car sunshade of the present invention, including flexible skeleton 1 and driving device 2, the flexible skeleton 1 It is that the fenestral fabric of at least four main national highways in China is formed, infall (Fig. 3) is by even by the cross link in length and breadth of series connection scissor-type mechanism Fitting 3 connects.

As shown in figure 4, the series connection scissor-type mechanism is made of several scissor-type linkage unit head and the tail hinged in series.

As shown in figure 5, the scissor-type linkage unit is hingedly made of outside connecting rod 4 and 5 scissor-type of inner link.

As shown in Figure 6 and Figure 7, the driving device 2 includes motor and open-and-close mechanism, and the open-and-close mechanism includes can Four nut sliders 11 of opening and closing movement are done, four nut sliders 11 of the flexible skeleton 1 and the open-and-close mechanism are fixed Connection, under motor driven, four nut sliders 11 of open-and-close mechanism do opening and closing movement, thus drive the flexible expansion of skeleton 1 or It shrinks (Fig. 2).

The open-and-close mechanism is made of screw rod 7, fixing bearing 8, bevel gear 9 and nut slider 11, and four have nut The screw rod 7 of sliding block 11 is perpendicularly fixed on pedestal 6 two-by-two by fixing bearing 8, and three screw rods 7 therein are located at 6 center of pedestal The end at place is fixed with bevel gear 9 and engages, the end of another screw rod 7 being located at 6 center of pedestal with and its positioned at same The end of the screw rod 7 of linear position is bound up by shaft coupling 10;A screw rod 7 therein and nut slider 11 thereon are Left-hand thread design, remaining three screw rod 7 and nut slider 11 thereon design for right-hand thread, the rotating forward of motor driven left-hand thread screw rod 7 or Reversion, drives the nut slider 11 on four screw rods 7 to synchronize and moves in or out.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not construed as limitation of the present invention, any based on this The modifications, equivalent substitutions and improvements etc. that the principle and technology of invention are done, should all be included in the protection scope of the present invention.
