[0026] See also Figures 1 to 4 The embodiment of the present application provides a backpack back, comprising a back plate 1, a backpack body 2 and a shoulder strap 3, the back plate 1 is connected to the backpack body 2, the shoulder strap 3 is arranged on the backpack body 2, a waist support 4 and a back pusher 5 are arranged on the back plate 1, and the waist support 4 is arranged below the back pusher 5; the waist support 4 comprises two groups of first protrusions 41, and a first tensioning cloth 42 is sewn and connected between the two groups of first protrusions 41; the back pusher 5 comprises two groups of second protrusions 51 and two groups of third protrusions 52, the two groups of second protrusions 51 are symmetrically arranged, the two groups of third protrusions 52 are symmetrically arranged on both sides of the two groups of second protrusions 51, the two groups of second protrusions 51 are arranged in a Y shape, the inner sides of the two groups of second protrusions 51 are sewn and connected with a second tensioning cloth 53, and the third tensioning cloth 54 is sewn and connected between the two groups of second protrusions 51 and the two groups of third protrusions 52.

[0027] Working principle and effect: When the user uses it, he puts both hands through the shoulder strap 3 so that the shoulder strap 3 falls on the shoulders of the human body. At this time, the waist support 4 and the back pusher 5 fit the back of the human body. Specifically, the first protrusion 41 of the waist support 4 is convex under the support of the first filler 43, and fits the curved lumbar structure of the human body, thereby supporting the waist. At the same time, the second protrusion 51 of the back pusher 5 is in a Y-shaped setting that is symmetrical on both sides. The Y-shaped structure of the second protrusion 51 can fit the curved arc of the scapula on the back of the human body, thereby dispersing the shoulder pressure on the back. The position of the third protrusion 52 is lower than the second protrusion 51 (such as Figure 3 As shown in the figure, when the user puts on the backpack, its position is close to the waist, which can disperse the shoulder pressure to the waist, thereby effectively reducing the shoulder load.

[0028] Furthermore, the first tensioning cloth 42 separates the two groups of first protrusions 41, and sews the first protrusions 41 to the back plate 1, thereby playing a role of fixed connection; similarly, the second tensioning cloth 53 and the third tensioning cloth 54 separate the two groups of second protrusions 51 and the two groups of third protrusions 52, so that they are symmetrically arranged on the left and right, so that they can fit the stress points of the back of the human body, and sew the second protrusions 51 and the third protrusions 52 to the back plate 1, thereby playing a role of fixed connection on the left and right.

[0029] In one embodiment, Figure 4 As shown, first fillers 43 are arranged inside the two groups of first protrusions 41. The first fillers 43 are preferably made of breathable elastic cotton, which not only supports the first protrusions 41, but also prevents hard objects from colliding with the spine and lumbar vertebrae, thereby improving the comfort of the backpack.

[0030] In one embodiment, Figure 4 As shown, the second filler 55 is disposed inside the two groups of second protrusions 51 and the two groups of third protrusions 52. The second filler 55 is preferably made of breathable elastic cotton, which not only supports the second protrusions 51 and the third protrusions 52, but also prevents hard objects from colliding with the spine and lumbar vertebrae, thereby improving the comfort of the backpack.

[0031] In one embodiment, Figure 3 As shown, the two groups of second protrusions 51 are centrally connected with a vertical recess 56. The vertical recess 56 is formed by sewing the second tensioning cloth 53 and the second protrusion 51. The centrally connected vertical recess 56 of the two groups of second protrusions 51 can emphasize the second protrusion 51, increase the supporting force of the second protrusion 51, and improve the supporting effect of the second protrusion 51.

[0032] In one embodiment, Figure 2 and Figure 5As shown, a mounting groove 21 is provided at the connection between the backpack body 2 and the shoulder strap 3, and one end of the shoulder strap 3 is fixed in the mounting groove 21. By providing the mounting groove at the rear end of the backpack, the shoulder strap 3 can be sewn and installed inside the backpack body 2, increasing the sewing surface of the shoulder strap 3 and the backpack body 2, enhancing the connection strength of the shoulder strap 3 and the backpack body 2, and effectively reducing the hidden danger of the shoulder strap 3 and the backpack body 2 being broken at the connection position.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
