Description
Technical Field
The invention relates to an automobile object covering curtain, in particular to the field of automobile parts, and discloses a multifunctional automobile object covering curtain which can bear larger weight and can store and take objects in and out of an automobile by utilizing the interaction of an extension force and a torsion spring in a curtain rolling pipe or an electrically-driven retraction force.
Background
With the development of automobile manufacturing industry, the technical requirements for the field of automobile parts are also rapidly increased. Many vehicles, such as SUVs, are equipped with a curtain in the trunk. Therefore, a wide variety of shade curtains and various related solutions are available in this field.
The object shielding curtain can shield various objects in the trunk, and light objects can be placed on the object shielding curtain cloth, so that the vehicle is tidier and more attractive, and is very practical. The object shielding curtain is composed of an object shielding curtain frame and an automatic rolling curtain mechanism arranged in the object shielding curtain frame, wherein two ends of the object shielding curtain frame are respectively provided with a curtain frame sealing cover mounting piece, the automatic rolling curtain mechanism comprises a rotary torsion spring and a rolling curtain pipe, object shielding curtain cloth is arranged on the rolling curtain pipe, and a connecting hard plate is fixed at the rear end of the object shielding curtain cloth. The rotary torsion spring always rolls the object shielding curtain cloth back to the curtain rolling pipe, so that the object shielding curtain cloth forms a retraction force rolling towards the curtain rolling pipe. The existing automobile object-covering curtain is characterized in that the object-covering curtain is automatically retracted, namely, the object-covering curtain cloth is stretched to the rear end of an automobile by manpower and is buckled for use. When the shade fabric is manually stretched, the rotary torsion spring is rotated by the fabric roller pipe to accumulate energy. When the object shielding curtain cloth is retracted, the energy accumulated by the rotary torsion spring when the object shielding curtain cloth is extended applies the power for rewinding the curtain cloth roller pipe. Namely, after the object shielding curtain cloth is stretched, the object shielding curtain cloth can automatically retract to the curtain cloth roller pipe without the action of external force. Although the technology is generally applied, various problems to be solved also appear in the using process.
The method comprises the following steps: because of hide the thing curtain when contracting the rolling on the curtain cloth reelpipe in automatic roller shutter mechanism, so hide the thing curtain all for soft material, tensile back, detain when the car rear end uses, because of hide thing curtain not have supporting component below, rely on the suspended plane that the tension of hiding the thing curtain realized one and hide the thing curtain. Therefore, only light objects can be placed on the plane of the object shielding curtain cloth, and a user can be inconveniently and carelessly put a little more important object on the plane of the object shielding curtain cloth.
The second is as follows: the tension of the object shielding curtain cloth is caused by the strength of the convolution torsion spring, so that: the larger the tension of the covering curtain cloth is, the larger the retraction force of the covering curtain cloth acted on the curtain cloth roller pipe by the rotary torsion spring is.
However, if the strength of the rotary torsion spring is increased, the object covering curtain cloth can be quickly retracted when the object covering curtain cloth is retracted and a large pulling force is needed during stretching, and the object covering curtain cloth can be quickly retracted when the hand is carelessly taken off, so that: the hardware arranged at the rear end of the object shielding curtain cloth can generate larger hard collision force with the object shielding curtain frame, so that the object shielding curtain is easily damaged.
In view of the above problems, those skilled in the art have devised and applied various solutions to solve the above problems, such as installing various dampers in the article-covering curtain, having two or more reduction planetary gears and damping springs.
For example, the utility model with patent No. 201620600560.5 discloses a car curtain and the invention with patent No. 201410849319.1 discloses a rolling control device of a car curtain rolling device, which both disclose technical solutions for solving the problems. However, in summary, various damping techniques, while slowing the retraction rate of the covering fabric, add structural complexity and do not address the load bearing problem of the flexible cord, as well as increasing the resistance to stretching of the covering fabric.
The third is: the existing object shielding curtain is automatically retracted, and can be used only by manually pulling and unfolding the object shielding curtain at the rear end of an automobile from the rear end and reversely buckling the object shielding curtain at the rear end of the automobile, so that the object shielding curtain can be used for storing and taking objects only from the rear end of the automobile. Thus, the rear door must be opened to operate the vehicle after the vehicle is stopped. It is not possible for a rear passenger to access the items in the trunk under the cover during driving, for example.
In view of the above, those skilled in the art have tried to develop a multifunctional automobile curtain that can be loaded and automatically extended and folded, and can provide an opposite natural extension force for the retraction force of the torsion spring or the electric drive in the rolling tube, and the retraction force and the extension force interact with each other, so that the inside and outside of the automobile can be used for storing and taking articles.
