After the user puts items of a certain mass into the bag body, the user adjusts the appropriate length through the bag strap. Then, when walking with the bag body on his back, under the action of inertia, the bag body first drives the damping block inside the damping groove of the damping shell through the connecting block and the connecting shaft, and moves downward relative to the damping shell. At this time, the two first tough bands are stretched. Under the elastic action of the first tough bands, the first tough bands pull the connecting shaft and the damping block upward. Finally, during walking, the bag body swings up and down with the steps, so that the bag body has a feeling of suspension, thereby reducing the feeling of weight during walking.

[0015] The technical effects achieved by the present invention are:

[0016] In the present invention, during actual use, after the user puts items of a certain mass into the bag body, the user adjusts the appropriate length through the bag strap, and then walks with the bag body on his back. Under the action of inertia, the bag body first drives the damping block inside the damping groove of the damping shell through the connecting block and the connecting shaft, and moves downward relative to the damping shell. At this time, the two first tough bands are stretched, and under the elastic action of the first tough bands, the first tough bands pull the connecting shaft and the damping block upward. Finally, during walking, the bag body sways up and down with the steps, so that the bag body has a feeling of suspension, thereby reducing the feeling of weight during walking.

[0017] In the present invention, it is worth mentioning that since the damping shell is an overall pancake-shaped structure, a circular groove is opened inside the damping shell, and a circular through hole is opened on the side of the damping shell, the damping block slides inside the circular groove, the diameter of the damping block is larger than the diameter of the circular through hole, the diameter of the damping block is smaller than the inner diameter of the circular groove, the diameter of the connecting shaft is smaller than the diameter of the circular through hole, and the connecting shaft slides in the circular through hole, so that the damping block can not only slide up and down, but also slide diagonally upward, and then in the process of human walking, as the footsteps change, the center of gravity of the human body tilts, and the two first toughness bands are inclined, and the overall V-shaped structure, so that the bag body can swing toward the corresponding diagonal upward, which is more adapted to the frequency of human walking than the original swing only in the vertical direction, so that the feeling of weight reduction provided is more obvious.

[0018] In the present invention, the frame and the damping shell are made of hard plastic material, and the aluminum alloy cores of the connecting shaft, the connecting block and the damping block are all made of aluminum alloy material, so that the suspension component added to the original package is lighter than the existing springs, rails, and telescopic rods, fundamentally reducing the feeling of weight.

[0019] In the present invention, the vertical poles and the horizontal poles are both made of hard and tough plastic. Specifically, the vertical poles and the horizontal poles can produce a certain deformation. Since carbon steel bars are provided at the middle parts of the horizontal poles and the vertical poles, the horizontal poles and the vertical poles can maintain a specific deformation under the action of the carbon steel bars. Finally, the horizontal poles and the vertical poles can fully fit the back of the user. Due to the good fitting effect, the user can feel more comfortable when carrying the backpack body.

[0020] In the present invention, the rubber jacket slides up and down with the inner wall of the circular groove inside the damping shell. Due to the provision of the rubber jacket, the rubber jacket will not continuously move relative to the inside of the damping shell. When the load mass changes relatively greatly, the load floating frequency will not be inconsistent with the travel frequency of the load-bearing person, thereby better maintaining the balance of the body and achieving a better suspension and weight reduction effect.

The upper ends of the two first toughness bands 36 are respectively connected to the top corners of the frame 31, and the two first toughness bands 36 are in a V-shaped structure as a whole.

[0030] In the present invention, during actual use, after the user puts items of a certain mass into the bag body 1, the user adjusts the appropriate length through the bag strap 2, and then walks with the bag body 1 on his back. Under the action of inertia, the bag body 1 first drives the damping block 33 inside the damping groove of the damping shell 32 through the connecting block 35 and the connecting shaft 34, and moves downward relative to the damping shell 32. At this time, the two first tough bands 36 are stretched, and under the elastic action of the first tough bands 36, the first tough bands 36 pull the connecting shaft 34 and the damping block 33 upward. Finally, during walking, the bag body 1 swings up and down with the steps, so that the bag body 1 has a feeling of suspension, thereby reducing the feeling of weight during walking.

[0031] It is worth mentioning that since the damping shell 32 is an overall pancake-shaped structure, a circular groove is opened inside the damping shell 32, and a circular through hole is opened on the side of the damping shell 32, the damping block 33 slides inside the circular groove, the diameter of the damping block 33 is larger than the diameter of the circular through hole, the diameter of the damping block 33 is smaller than the inner diameter of the circular groove, the diameter of the connecting shaft 34 is smaller than the diameter of the circular through hole, and the connecting shaft 34 slides in the circular through hole, so that the damping block 33 can not only slide up and down, but also slide diagonally upward, and then in the process of human walking, as the footsteps change, the center of gravity of the human body tilts, and the two first toughness bands 36 are inclined, and the overall V-shaped structure, so that the bag body 1 can swing toward the corresponding diagonal upward, which is more adapted to the frequency of human walking compared to the original swing only in the vertical direction, making the weight reduction feeling provided more obvious.

[0034] In the present invention, it should be noted that the vertical rod 312 and the horizontal rod 313 are both made of hard and tough plastic. Specifically, the vertical rod 312 and the horizontal rod 313 can produce a certain deformation. Since a carbon steel bar 315 is provided at the middle of the horizontal rod 313 and the vertical rod 312, under the action of the carbon steel bar 315, the horizontal rod 313 and the vertical rod 312 can maintain a specific deformation.

Due to the provision of the rubber jacket 332, the rubber jacket 332 will not continuously move relative to the inside of the damping shell 32. When the load mass changes relatively greatly, it will not cause the load floating frequency to be inconsistent with the travel frequency of the load-bearing person, thereby better maintaining the balance of the body and achieving a better suspension and weight-reducing effect.
