Description

Car sunshade

Technical field

The utility model is related to a kind of Automobile Products, more particularly to a kind of car sunshade.

Background technology

With the improvement of people ' s living standards, the quantity of private car is growing day by day, due to corresponding auxiliary facility build it is stagnant Afterwards, most vehicles are parked for outdoor, and summer vehicle is irradiated by the sun, and in-car temperature can be raised drastically such as food steamer one As, It is sultry and stifling, sensation is felt bad very much.Long-term being exposed to the sun of vehicle drenches with rain and accelerates the aging of car paint simultaneously.Have impact on vehicle Riding experience, shortens the service life of vehicle.

Utility model content

The utility model is intended to for problem present in background technology, there is provided a kind of easy-to-use car sunshade of simplicity, Prevent burning sun to be exposed to the sun automobile, improve and drive comfort level.

The technical scheme that the utility model is used is：A kind of car sunshade, including flexible skeleton and drive device, it is described Flexible skeleton is the fenestral fabric that at least four main national highways in China are formed by the cross link in length and breadth of series connection scissor-type mechanism, its infall Connected by connector;The series connection scissor-type mechanism is made up of several scissor-type linkage unit head and the tail hinged in series;The drive Dynamic device includes motor and open-and-close mechanism;The open-and-close mechanism includes four nut sliders that can do opening and closing movement;Institute Flexible skeleton is stated to be fixedly connected with four nut sliders of the open-and-close mechanism, under motor driving, four spiral shells of open-and-close mechanism Female sliding block does opening and closing movement, so as to drive flexible skeleton to launch or shrink.

Described scissor-type linkage unit is hinged and is constituted by outside connecting rod and inside connecting rod scissor-type.

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

The utility model scientific structure design rationally, storage after small volume, lightweight, low cost, operation and installing/dismounting Convenient, flexibility is strong, is not limited by regional condition, does not influence the normal of vehicle to use.

Specific embodiment：

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in figure 1, a kind of car sunshade of the utility model, including flexible skeleton 1 and drive device 2, it is described flexible Skeleton 1 is the fenestral fabric that at least four main national highways in China are formed by the cross link in length and breadth of series connection scissor-type mechanism, its infall（Figure 3）Connected by connector 3.

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

As shown in figure 5, described scissor-type linkage unit is hinged and is constituted by outside connecting rod 4 and the scissor-type of inside connecting rod 5.

As shown in Figure 6 and Figure 7, the drive 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, the flexible skeleton 1 is fixed with four nut sliders 11 of the open-and-close mechanism Connection, motor driving under, four nut sliders 11 of open-and-close mechanism do opening and closing movement, thus drive flexible skeleton 1 launch or Shrink（Fig. 2）.

Described open-and-close mechanism is made up of screw mandrel 7, fixing bearing 8, bevel gear 9 and nut slider 11, and four carry nut The screw mandrel 7 of sliding block 11 is perpendicularly fixed on base 6 two-by-two by fixing bearing 8, three screw mandrels 7 therein positioned at the center of base 6 The end at place is fixed with bevel gear 9 and engages, the end positioned at the center of base 6 of another screw mandrel 7 with and its be located at it is same The end of the screw mandrel 7 of linear position is bound up by shaft coupling 10;A screw mandrel 7 therein and nut slider thereon 11 are Left-hand thread is designed, and remaining three screw mandrel 7 and nut slider thereon 11 are designed for right-hand thread, motor driving left-hand thread screw mandrel 7 rotate forward or Reversion, drives the nut slider 11 on four screw mandrels 7 synchronously to move in or out.

Preferred embodiment of the present utility model is the foregoing is only, is not construed as to limitation of the present utility model, appointed Modification, equivalent and improvement what is made based on principle of the present utility model and technology etc., should be included in the utility model Protection domain within.
