Description
Technical Field
The invention relates to an automobile object covering curtain, in particular to a full-automatic power supply contact device of an electric object covering curtain, which is telescopic in a guide rail way and provided with an extension bearing mechanism, and can store and take objects in and out of an automobile by utilizing the interaction of extension force and electric 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 existing automobile object covering curtain is mostly of a semi-automatic type, namely, an automatic roller shutter mechanism is arranged in the automobile object covering curtain, the automatic roller shutter mechanism comprises a rotary torsion spring and a roller shutter pipe, object covering curtain cloth is arranged on the roller shutter pipe, and a hard plate pull block is fixedly connected to the rear end of the object covering curtain cloth. When in use, the curtain cloth is required to be manually stretched and buckled at the rear end of the automobile, and the object shielding curtain cloth can automatically retract to the curtain cloth roller pipe without the action of external force. Although this technique is commonly used, various problems to be solved arise in the use process.
The method comprises the following steps: because of hiding the thing cord fabric and all adopting soft material, tensile back, detain when the car rear end is used, because of hiding the thing cord fabric below not having supporting component, rely on the tension that hides the thing cord fabric to realize a unsettled plane that hides the thing cord fabric. The covering fabric has no load-bearing capacity.
The bearing capacity problem of the object shielding curtain cloth relates to the tension of the object shielding curtain cloth, and the tension of the object shielding curtain cloth is derived from the strength of a torsion spring arranged in a curtain rolling pipe. Therefore: the larger the torsion of the torsion spring acting on the cord fabric roller pipe is, the larger the tension of the object shielding cord fabric is, and conversely, the smaller the tension of the object shielding cord fabric is.
However, if the strength of the torsion spring is increased, a large pulling force is needed during stretching, and meanwhile, when the object covering curtain is retracted, the object covering curtain is retracted rapidly by carelessly taking off the hand, 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 this problem, most of the existing technical solutions are to install various dampers, etc. in the object covering curtain, and there are two or more reduction planetary gears and damping springs, etc. 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, both of which 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 second is as follows: hide thing curtain rear side and all be provided with a hardboard pull block, this hardboard pull block can rock from top to bottom in the car goes, and especially car hides the thing curtain and contracts the back, and it rocks from top to bottom and can produce the abnormal sound, so in this problem, has also designed various solutions now, and its structure is also more complicated, but difficult full solution.
For example, patent No. 201710014969.8 discloses a pressing and positioning device for a curtain edge board of a blind.
The third is: the existing automobile object shading curtain is automatically retracted, and can be used only by being pulled and unfolded at the rear end of an automobile by manpower to be buckled at the rear end of the automobile when in use, so that objects can be stored and taken 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. The existing automobile object shading curtain has no technical scheme for storing articles in an automobile.
The fourth step is: the automobile object covering curtain solves the problem of position adjustment of the rear row seat, and has the damage caused by extrusion and collision of the rear row seat to the object covering curtain. For solving this problem, for the adjustment of back row seat position, the utility model with patent No. 201821518188.9 discloses a slidingtype car hides thing curtain, has adopted and has set up two little curtain cloth at the front side that hides thing curtain frame, and this also is the technical scheme that current hides thing curtain and generally adopts, but it also can't solve little curtain cloth tension inadequately, can not the problem of bearing.
The fifth step is: if the automobile is designed to be fully automatically extended and retracted, matching of a guide rail is better, but the tail of the automobile is known to be large in front and small in back, namely, the distances between the guide grooves on the left side and the right side are different, and the two sides are also bent, and when the object covering curtain is extended, the curtain cloth of the object covering curtain is also in a shape of large in front and small in back, so that the technical problem is difficult to solve.
Like the utility model discloses a whole utility model of guide rail hide thing curtain gently press automatic recovery mechanism and the utility model of 201520025495.3 discloses a hide thing curtain subassembly that hides thing curtain semi-conductive rail formula installation structure chart and use this mounting structure, both do not consider above problem, so its technical scheme is not according with reality like the utility model of patent number 201721492869.8.
With the continuous improvement of the living requirements of people, the requirements of automobiles and parts are also improved, and full automation is also generally applied, but based on the various problems and the particularity of space and function, a complete technical scheme of a full-automatic automobile object covering curtain does not exist at present.
In view of the above, those skilled in the art will try to develop a power supply contact device of an electric object covering curtain, which is fully automatic and track-guided, has a load-bearing function, can be automatically extended and folded, provides an opposite natural extension force for the electric driving force, and has the advantages of interaction between the electric driving force and the extension force, uniform extension and uniform speed safety, and convenient storage and retrieval of objects both inside and outside the vehicle.
