Description

Technical Field

[0001] The utility model relates to the technical field of automatic umbrellas, in particular to an automatic umbrella power-assisted folding structure. Background Art

[0002] An umbrella is a tool used to block rain, snow or sunlight. It is generally composed of an umbrella cover, umbrella ribs and an umbrella handle. Traditional umbrellas need to be opened by hand, which is quite laborious, especially in heavy rain. In order to solve this problem, inventors Seidl Joachim and Stieler Claus from the Federal Republic of Germany invented an automatic umbrella that can be opened with just one click of a button. However, the automatic umbrella is opened with the help of an opening spring, which also makes it difficult to fold the umbrella. It requires a lot of strength and may be difficult for children and women to fold it. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0022] See also Figure 1-Figure 3The utility model discloses an automatic umbrella assisted folding structure, including a sliding sleeve 10, a fixed sleeve 11, a handle, a reel 22, a coil spring 27, a horizontal bevel gear 26, a vertical bevel gear 23 and a guide wheel 30.

[0023] Among them, the sliding sleeve 10 is slidably sleeved on the fixed sleeve 11. The matching structure of the sliding sleeve 10 and the fixed sleeve 11 in the embodiment of the utility model is consistent with the matching structure of the sliding sleeve and the fixed sleeve of the automatic umbrella in the prior art, and the embodiment of the utility model will not be repeated.

[0024] like Figure 1 and Figure 2 As shown, a handle is fixedly sleeved at the lower end of the fixed sleeve 11, and the handle comprises a first handle half shell 21 and a second handle half shell (not shown in the figure). The first handle half shell 21 and the second handle half shell are buckled with each other and fixed by screws and studs to form a handle. The handle has an L-shaped structure, and the upper end of the handle is fixedly buckled on the lower end of the fixed sleeve 11, so that the fixed sleeve 11 is fixedly connected to the handle. An L-shaped mounting cavity is provided in the handle, and a horizontal shaft 24 is rotatably provided on the lower side wall of the vertical cavity of the L-shaped mounting cavity. Specifically, a first bearing seat 25 is fixedly provided on the lower side wall of the vertical cavity of the L-shaped mounting cavity, and one end of the horizontal shaft 24 is rotatably sleeved in the first bearing seat 25, and a vertical bevel gear 23 is fixed to the other end of the horizontal shaft 24. A wire reel 22 is also fixedly sleeved on the middle part of the horizontal shaft 24, and a lower bottom wall of the horizontal cavity of the L-shaped mounting cavity is rotatably provided. There is a vertical shaft 28. Specifically, a second bearing seat 29 is fixedly arranged on the lower bottom wall of the horizontal cavity of the L-shaped installation cavity. The lower end of the vertical shaft 28 can be rotatably sleeved in the second bearing seat 29. The horizontal bevel gear 26 is fixed to the upper end of the vertical shaft 28. The vertical bevel gear 23 is meshed with the horizontal bevel gear 26. A coil spring 27 is fixedly sleeved in the middle of the vertical shaft 28. A fixing hook 211 is arranged on the side wall of the horizontal cavity of the L-shaped installation cavity. Specifically, the fixing hook 211 is an integral structure with the first handle half shell 21 or the second handle half shell. The fixing hook 211 is connected with the telescopic end of the coil spring 27. A wire wheel 30 is arranged on the sliding sleeve 10. The wire 221 wound by the wire reel 22 is connected to the fixed sleeve 11 by bypassing the wire wheel 30. When the umbrella is in an open state, the coil spring 27 is in a tightened state. When the umbrella is in a contracted state, the coil spring 27 is in an extended state.

[0025] In the example of the utility model, the guide wheel 30 can be installed inside the sliding sleeve 10 or outside the sliding guide wheel 30, but the line 221 output by the guide wheel 30 and the reel 22 cannot interfere with the automatic umbrella assist spring set in the sliding sleeve 10 and the fixed sleeve 11.

[0026] The working principle of the automatic umbrella assisting umbrella folding structure of the embodiment of the utility model is as follows: when the automatic umbrella switch is pressed, the automatic umbrella is opened under the action of the automatic umbrella assisting spring. During the opening process of the automatic umbrella, the sliding sleeve 10 rises and drives the wire wheel 30 to rise synchronously. Since the wire 221 output from the wire reel 22 is fixedly connected to the fixed sleeve 11 through the wire wheel 30, the wire wheel 30 rises and drives the wire 221 output from the wire reel 22 to be continuously output, and at the same time drives the wire reel 22, the vertical bevel gear 23 and the horizontal shaft 24 to rotate. 23 is meshed with the horizontal bevel gear 26, and the vertical bevel gear 23 rotates while driving the horizontal bevel gear 26 to rotate and drive the vertical shaft 28 to rotate, and at the same time the coil spring 27 is tightened until the automatic umbrella is opened and the coil spring 27 reaches the maximum tightening state; when the umbrella is folded, while the person pulls the sliding sleeve 10 down, the coil spring 27 stretches and drives the horizontal bevel gear 26 to rotate in the opposite direction, the horizontal bevel gear 26 rotates to drive the vertical bevel gear 23 to rotate, the vertical bevel gear 23 rotates to drive the horizontal shaft 24 to rotate and the reel 22 to rotate, and the reel 22 rotates to retract the line 221.

[0027] In the example of the present utility model, the vertical bevel gear 23 is a small-diameter bevel gear, and the horizontal bevel gear 26 is a large-diameter bevel gear. Setting the horizontal bevel gear 26 as a large-diameter bevel gear can, on the one hand, help provide a larger space for the winding spring 27 to stretch, and at the same time increase the rotation speed of the reel 22, thereby increasing the line-reeling 221 speed of the reel 22.

[0028] In the example of the utility model, the outer wall of the handle is provided with an anti-slip groove 212, and the handle is also covered with an anti-slip cover 20. The anti-slip cover 20 can not only cover the screws connecting the first handle half shell 21 and the second handle half shell, but also improve the anti-slip performance of the handle together with the anti-slip groove 212.

[0029] The utility model shows an automatic umbrella assisting folding structure, which is provided with a winding wire 221 device 22, a winding spring 27, a horizontal bevel gear 26, a vertical bevel gear 23 and a wire 221 wheel. When the automatic umbrella is folded, the force generated by the resetting of the winding spring 27 is transmitted through the horizontal bevel gear 26 and the vertical bevel gear 23, so that the winding wire 221 device 22 pulls the sliding sleeve 10 downward through the wire 221, thereby assisting the folding of the umbrella. At the same time, since the wire 221, the wire 221 wheel and the sliding sleeve 10 form a movable pulley, the force required for folding the umbrella is further reduced, and the convenience of folding the umbrella is improved.

[0030] The technical solution of the utility model is described in detail above in combination with specific embodiments, and the described specific embodiments are used to help understand the concept of the utility model. Derivations and variations made by those skilled in the art based on the specific embodiments of the utility model also fall within the protection scope of the utility model.
