As shown in fig. 1 to 3, an embodiment of the present invention provides a backpack, which includes a backpack body 1 and two straps 2 connected to the backpack body 1, where the straps 2 include an upper strap 21 and a lower strap 22, one end of the upper strap 21 is connected to the front upper end of the backpack body 1, the other end of the upper strap 21 is provided with an adjusting buckle 3, one end of the lower strap 22 is connected to the front lower end of the backpack body 1, the other end of the lower strap 22 passes through the adjusting buckle 3, and the backpack body 1 is provided with a balancing device for monitoring a balance state of the backpack body 1 and confirming a length relationship between the two straps 2 according to the balance state. Like this, in the use, the user carries out preliminary adjustment to the length of braces 2 with the mode of eyeballing alignment, waits afterwards to confirm the length relation between two braces 2 according to the balanced state that balancing unit shows after with the knapsack braces on the shoulder to carry out further accurate regulation to two braces 2 lengths, make the heavy burden of user's both shoulders unanimous, guarantee the balance of knapsack in the braces in-process, with the travelling comfort that improves the braces.

Further, the backpack passes the lower braces 22 of the adjusting button 3 and is easy to loosen in the using process, so that the length of the braces 2 changes, the balance state of the backpack in the braces process can be monitored and known in real time through the balancing device, the length of the braces 2 can be corrected by a user in time, and the comfort of the backpack in the braces process is improved.

Alternatively, each of the lower straps 22 may be connected to the left and right sides of the lower end of the bag body 1, and the connection between each of the lower straps 22 and the bag body 1 may be treated to prevent tearing after a long time use.

Alternatively, as shown in fig. 1, the adjusting button 3 may be a letter-of-Chinese button, and the adjusting button 3 is made of an alloy material or plastic.

Optionally, the balancing device includes a balancing sensor 41 located at the upper end of the back of the backpack 1 and two display devices 42 respectively provided on the upper back strap 21 for displaying the balancing state of the balancing sensor 41, and the two display devices 42 are electrically connected to the balancing sensor 41. The balance sensor 41 is positioned in the middle of the upper end part of the back surface of the bag body 1, and when the bag body 1 inclines, the balance sensor 41 can sensitively reflect the balance state of the bag body 1.

Optionally, the display device 42 may be an indicator light (not shown in the figure), and the indicator light may display different colors according to the balance state of the bag body 1, such as: when the indicator lights on the two upper straps 21 are both green, the bag body 1 is in a balanced state, and when the indicator lights on the two upper straps 21 are green and red, the bag body 1 is in an unbalanced state, and in this state, the length of the lower strap 22 in the strap in which the red indicator light is located can be adjusted by taking the length of the strap in which the green indicator light is located as a standard length until the red indicator light is green.

In practical application, in order to improve the convenience of adjusting the length of the shoulder strap 2, the display device 42 can also be a display screen, the display screen can display the balance state of the balance sensor 41 in a digital form, and when the bag body 1 is in the balance state, the numerical values displayed by the display screens on the two upper shoulder straps 21 are the same; when the bag body 1 is in an unbalanced state, the strap with smaller number displayed in the display screen is used as a standard, the length of the other strap is adjusted, and the adjustment value is the absolute value of the difference value of the numbers in the two display screens until the numerical values displayed by the display screens on the two upper straps 21 are the same.

As an alternative embodiment, a level meter can be arranged in the middle of the upper end of the backpack body, and people can know whether the backpack is in a balanced state during the strap process through the level meter, and under the structure, the length adjustment of the backpack strap 2 needs to be assisted by a second person, and the backpack with the structure is suitable for children who are younger and have weak independent operation ability.

Optionally, each of the upper straps 21 may be slidably connected to the bag body 1, that is, the two upper straps 21 may move in opposite directions or back to back according to the shoulder widths of different users, so as to adjust the distance between the two upper straps 21.
