Technical Field

The invention relates to an object shielding curtain and a sun-shading curtain, in particular to a reel pipe energy storage buffer device with a buffer device, which is applied to the object shielding curtain and the sun-shading curtain and has simple structure and good stability.

Background

With the rapid development of the field of automobile parts. Many kinds of automobile object shades and sun shades are designed and produced, but the structural components of the automobile object shades and the sun shades are all provided with cloth rolling pipes, and the technical structure of the automobile object shades and the sun shades is also very important for the integral automobile object shades and the sun shades.

In the existing sunshade curtain and the object shielding curtain which are produced in mass production, the automatic reset kinetic energy of the roller shutter tube of the sunshade curtain and the object shielding curtain is more, and the spiral spring arranged in the roller shutter tube is adopted, so that the spiral spring is used for storing energy when the curtain cloth is manually stretched, and can be used as the kinetic energy when the curtain cloth is automatically retracted to implement the automatic retraction of the curtain cloth.

The commonly used solution is shown in fig. 9: the sun-shading curtain or the object-shading curtain consists of a curtain frame 6, a rolling curtain pipe A41 and a curtain, wherein a stress shaft 42 is fixedly arranged in a curtain frame mounting end cover 7 at one end of the curtain frame 6, the rolling curtain pipe A41 is movably arranged on the stress shaft 42, and the other end of the rolling curtain pipe A41 is movably connected to the curtain frame mounting end cover 7 at the other end of the curtain frame 6 in a shaft mode. The roller shutter pipe A41 is hollow, a plurality of limiting strips are arranged on the inner wall of the roller shutter pipe A41, a limiting piece 43 is arranged in the roller shutter pipe A41, a limiting groove matched with the limiting strips is arranged on the limiting piece 43, the limiting piece 43 can move in the roller shutter pipe A41, but the roller shutter pipe A41 can only rotate along with the roller shutter pipe A41, and when the roller shutter pipe A41 rotates relative to the stress shaft 42, namely when the curtain is stretched, the spiral torsion spring 45 connected between the stress shaft 42 and the limiting piece 43 can be twisted to store energy; however, the torsion coil spring 45 is tightened and shortened, and conversely, is lengthened. The helical torsion spring 45 needs a long length to satisfy the revolution of the roller shutter pipe a41 when the curtain is stretched, and the helical torsion spring 45 is relatively soft, so that the helical torsion spring can inevitably touch the inner wall of the roller shutter pipe a41 when rotating, and generate abnormal noise. And the production and assembly process is also complex, so the production cost is correspondingly increased. And because there is no buffer device, the speed is too fast when the curtain cloth retracts, the brace at the outer end of the curtain cloth normally collides with the curtain frame fast and hard, the potential safety hazard is likely to be generated when in use, and the service life of the curtain cloth is reduced.

The prior utility model with the patent number of 201020152757X discloses an automobile sun-shading curtain. Although the technical scheme has a simple structure, the coil spring transmission mechanism is arranged on one side of the reel pipe, relatively occupies the public space on the outer side, and increases the extra total length or shortens the width of the curtain cloth.

Another patent application No. 2011100251434 discloses a roller shutter power device. The structure is too complex and unreasonable.

The above two technical solutions are theoretically possible, but both cannot be really implemented and produced in mass production in reality.

In view of the above, those skilled in the art will try to develop a coiled pipe energy storage buffer device with more reasonable structure, simple production and assembly process, stable performance, safety and durability.

The spring is formed by coiling a spring strip with good rigidity, is a traditional energy storage part which is widely applied in various fields and has obvious effect, and is a good technical innovation if being reasonably and scientifically applied to required structural components.

The inner diameter of the roller shutter tube 3 in the invention is possibly a little bit smaller, and the diameter is generally about 22 mm, so the thickness of the spiral spring has relative influence, and the thinner the spiral spring is, the smaller the torsion of the spiral spring is; however, the shade tube 3 of the present invention has a relative length, so the width of the spring 13 can be increased to increase the torsion of the spring 13, and the wider the spring 13 is, the longer the length of the rotation shaft 12 is, and the better, i.e., more stable, the concentricity during rotation is.

The two ends of the roller blind pipe 3 can be symmetrically designed and installed, so that the roller blind pipe 3 is more stable in stress and rotation, and the torsion is larger.

The rotary damper 21 is a device for providing motion resistance and reducing motion energy, and is composed of a damping rotating shaft 27 and a resistance impeller which rotate in industrial viscous oil. And the resistance function of gentle rotation is achieved. The rotary damper 21 is connected with the rotating shaft 12, so that after the energy of the spring 13 is stored when the curtain cloth 5 is stretched, the roller shutter tube 3 can be quickly rotated to play a role in buffering and decelerating when the curtain cloth 5 retracts and the energy of the spring 13 is released, and the safety and the durability in use are improved.

Then, the sleeve 22 outside the rotary damper 21 is fixed to the damping sleeve inside the interconnecting piece 23, and the damping spindle 27 is inserted into the sleeve hole 18 at the inner end of the rotary shaft 12, so that the damping spindle 27 is integrally connected to the rotary shaft 12, and the spring case 11 is integrally connected to the rotary damper 21 and the interconnecting piece 23.
