Description

Backpack with sun-shading device

Technical Field

The utility model relates to a backpack with a sun-shading device, which belongs to the technical field of daily supplies.

Background

The backpack has the advantages of convenient carrying, liberation of hands, light weight, good wear resistance and the like, and provides a lot of convenience for going out. However, the existing backpack has single function, and the main purpose of the backpack is to accommodate and carry daily necessities.

In hot summer, people need to carry various articles and sunshade umbrellas when going out, so that the carrying burden is increased, the sunshade umbrellas are easy to lose, and the hands of people cannot be better liberated due to the fact that the sunshade umbrellas are held by hands, and the use is inconvenient. Although many shoulder bags with the sunshade devices are arranged at present, the shoulder bags are required to be taken down by people when the backpack is used, the sunshade devices are pulled open manually, the operation is complex, and the practicability is low.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide this take solar protection devices's shoulders bag, can overcome the not enough of prior art.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides a take sunshade device's shoulders bag, includes shoulders bag body, shoulders bag body back is equipped with the braces, shoulders bag body bilateral symmetry is equipped with electronic telescopic machanism, is connected with the sunshade structure of autogiration closure and expansion on electronic telescopic machanism's top through the gear train.

The electric telescopic mechanism comprises a micro stepping motor and a battery pack connected with the micro stepping motor, and the side part of the backpack body is provided with a start button of the micro stepping motor; the miniature stepping motor is connected with the screw rod shaft, and a screw sleeve which stretches along the screw rod shaft is sleeved on the screw rod shaft.

The sunshade structure comprises a rotating shaft, wherein a sunshade plate paved on the front part of the backpack body is fixedly connected to the rotating shaft, second bevel gears are arranged at two ends of the rotating shaft, a first bevel gear matched with the rotating shaft is arranged at the top end of the screw sleeve, and the rotating shaft is rotatably connected with the screw sleeve through a gear set consisting of the first bevel gear and the second bevel gear.

The sun shield is a light plastic sheet; or the sun shield is made of sun-shading cloth, thin rods for supporting the sun-shading cloth are arranged on the periphery of the sun-shading cloth, and the thin rods are fixedly connected with the rotating shaft.

The screw shaft, the screw sleeve and the rotating shaft are all made of aluminum alloy materials.

The first bevel gear and the second bevel gear are made of light plastic.

Compared with the prior art, the utility model discloses a take solar protection devices's shoulders bag, it includes the shoulders bag body, shoulders bag body back is equipped with the braces, shoulders bag body bilateral symmetry is equipped with electronic telescopic machanism, is connected with the closed sunshade structure who expandes of autogiration through the gear train on electronic telescopic machanism's top. The electric telescopic mechanism comprises a micro stepping motor and a battery pack connected with the micro stepping motor, and the micro stepping motor is connected with the screw rod shaft-screw sleeve assembly; the sunshade structure comprises a rotating shaft, wherein the rotating shaft is fixedly connected with a sunshade board paved on the front part of the backpack body, and two ends of the rotating shaft are rotatably connected with the thread sleeve through a bevel gear set. When the sun shading board is unfolded, the miniature stepping motor rotates forwards to drive the screw rod shaft to rotate, so that the screw sleeve extends out along the screw rod shaft in a rotating mode, and meanwhile, when the screw sleeve rotates, the first bevel gear at the top end of the screw sleeve drives the second bevel gear to rotate, so that the sun shading board is unfolded around the rotating shaft. Similarly, when the micro stepping motor 3 is closed, the operation can be completed by reversing the direction.

The utility model discloses simple structure thinks about ingeniously, has not only improved the utilization ratio of backpack, and the simple operation can realize that the automation of sunshading board struts and closes moreover, and the travelling comfort is good, and the practicality is strong.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention:

as shown in fig. 1-3, a backpack with a sun-shading device comprises a backpack body 1, straps 2 are arranged on the back of the backpack body 1, electric telescopic mechanisms are symmetrically arranged on two sides of the backpack body 1, and the top ends of the electric telescopic mechanisms are connected with a sun-shading structure which can be automatically rotated, closed and unfolded through a gear set.

The electric telescopic mechanism comprises a micro stepping motor 3 and a battery pack 4 connected with the micro stepping motor, and a starting button 5 of the micro stepping motor 3 is arranged on the side part of the backpack body 1; the micro stepping motor 3 is connected with a screw rod shaft 6, and a screw sleeve 7 which stretches along the screw rod shaft 6 is sleeved on the screw rod shaft 6.

The sunshade structure comprises a rotating shaft 8, wherein a sunshade plate 9 paved on the front part of the backpack body 1 is fixedly connected to the rotating shaft, second bevel gears 10 are arranged at two ends of the rotating shaft 8, and a first bevel gear 11 matched with the rotating shaft is arranged at the top end of the screw sleeve 7, so that the rotating shaft 8 is rotatably connected with the screw sleeve 7 through a gear set consisting of the first bevel gear 11 and the second bevel gear 10.
