Technical Field

The utility model relates to a personal articles for daily use field specifically is a light knapsack with subtract burden and function of charging.

Background

The backpack is a daily product used for storage in life, and is an indispensable product for activities such as work commuting, business trip, tourism and the like.

With the development of science and technology, small-sized electronic products for personal use, such as mobile phones, tablets, smart watches and the like, are increasing at present. But the development of the battery technology is limited, the cruising ability of the current small-sized electronic product is insufficient, and the electric quantity is exhausted in eight hours; it is often necessary to carry a portable power source for endurance.

At present, some backpacks with charging function are available, for example, patent CN202680967U discloses a solar charging backpack, which generates electricity by solar energy through photovoltaic panels installed on the surface of the backpack. However, such solar power backpacks have several drawbacks:

when people walk, people usually can consciously avoid sunlight for body feeling comfort; so that the solar panel receives insufficient sunlight; and the charging function cannot be realized at night.

The solar panel is required to be arranged on the surface of the backpack, and the black solar panel is limited at a certain position on the surface of the backpack in appearance, so that the selection of the appearance of the backpack is limited;

the solar panel is fragile and has enough power to generate power only in a large area, the backpack cannot be folded when the area is large, and the shape and the appearance of the backpack are limited and cannot be folded like other common backpacks; the device occupies a very large place in a crowded scene, and brings inconvenience to the device and other people; and the solar panel is easy to be crowded and broken, which not only affects the normal use, but also can hurt people.

The solar panel is heavy, increasing the weight that people bore.

Detailed Description

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

As shown in fig. 1 and 2, a support plate covering between the upper support 7 and the lower support 8 and components such as a backpack body and the like mounted in the support plate are omitted in fig. 1 and 2; and the shoulder straps installed in the direction of the back plate 15 and the lifting straps above the back plate are omitted. In fig. 1, the voltage regulator module 13, the battery 14, the charging interface 16 and the electrical lines electrically connected to the generator 2 are omitted for better illustration of the internal structure thereof, which is shown in fig. 2.

In order to protect the spine of a person from bending or overloading, a hard back plate 15 is arranged at the position close to the back of the person in the prior backpack, so that the person is prevented from bending forwards unconsciously when the backpack is loaded with a large amount of heavy weight, although the posture has relaxed feeling at that time, certain vertebra is overloaded, over-fatigue is caused in a short term, and chronic diseases such as strain and lateral bending are caused in a long term. After the backboard 15 is arranged, the back of a person is forced to be vertical and evenly stressed, and the defects are avoided.

An upper support member 7 is arranged above the back plate 15, and a lower support member 8 is arranged below the back plate 15; backplate 15, upper support piece 7, lower support piece 8 constitute utility model's basic skeleton jointly, and form a cavity between the three and be used for the installation the utility model discloses an other part.

Between the upper support 7 and the lower support 8, a pair of vertical guide rails 1 are symmetrically arranged on two sides of the back plate 15; a pair of sliding wheels 10 is arranged at the bottom of the guide rail 1;

an elastic band fixing shaft 12 is fixedly arranged between the guide rails 1; the elastic band fixing shaft 12 is fixed and immovable relative to the back plate 15. Two identical elastic belts 3 are sleeved on the elastic belt fixing shaft 12; the lower end of the elastic band 3 is sleeved on the shaft of the elastic adjusting component 11; the elastic force adjusting assembly 11 comprises a shaft and fixing pieces at two ends, the fixing pieces at the two ends are arranged in the through groove of the guide rail 1, the through groove of the guide rail 1 is in a shape shown in figure 1, 3-level or multi-level adjustment is arranged as required, and the loosening degree of the elastic belt 3 is adjusted. A pair of limit blocks 4 are arranged below the elastic band fixing shaft 12 and contact with the limit blocks to limit the position of the elastic band fixing shaft 12.

Four second pulleys 6 are arranged in the guide rail 1; the four second pulleys 6 are respectively arranged at the upper side and the lower side of the two guide rails 1; when a person walks, the second pulley 6 slides in the guide rail 1 along the direction of the guide rail 1 due to the vibration caused by the steps; meanwhile, the elastic belt 3 can also strengthen the vibration of the pace to further strengthen the up-and-down sliding degree of the second pulley 6; in addition, a first pulley 5 is arranged in the guide rail 1, each first pulley 5 is contacted with a corresponding second pulley 6, and the first pulley 5 and the second pulley 6 are mutually vertical in a top view or a bottom view; the first pulleys 5 are connected with the respective micro-generators 2; the first pulley 5 and the second pulley 6 contact each other to generate electricity by transmitting vibration to the generator 2. The generator 2 is converged into the voltage stabilizing module 13 through corresponding wires to maintain a fixed voltage to charge the battery 14; a plurality of charging interfaces 16 are provided in the battery 14; the charging interface 16 is connected to various USB interfaces or other types of interfaces to charge electronic devices such as a mobile phone, a smart watch, a notebook, or a charger. In addition, a spring 9 is arranged between the generators 2 on the same side; the spring 9 is similar to the elastic belt 3, can also generate vibration and drive the generator 2 to generate electricity by the same transmission of the elastic belt.

When a user walks with the utility model, the generator 2 is triggered to generate electricity through vibration; meanwhile, the elastic components such as the elastic band 3 and the spring 9 are arranged inside; when the feet are upward during walking, the stored force of the elastic band 3 and the spring 9 is released upward because the feet are downward in the previous step; the feet are downward and the same reason is adopted; the delayed release force of the elastic band 3 and the spring 9 can make the vertical amplitude of the walking of the person smaller and more labor-saving.
