Description

Technical Field

[0001] This patent relates to the field of backpacks, and in particular to a lightweight and breathable backpack. Background Art

[0002] Existing backpacks generally include a backpack body and shoulder straps, and the shoulder straps are fixed to the back of the backpack body. For such backpacks, the side that abuts against the user's back, i.e., the back of the backpack body, is usually made of soft materials such as cloth, and the thickness of the cloth is relatively thin, so that when the user is carrying the backpack, the back will be directly compressed by the items in the bag. In particular, when teenagers use such backpacks, it is easy for the teenagers' torsos to lean forward and their shoulders to be retracted, resulting in hunchbacks. In order to solve the above problems, manufacturers generally provide a back interlayer on the back of the backpack body, and the back interlayer is provided with soft protrusions that are in contact with the back of the human body. In this way, the user will not be directly compressed by the items in the bag when carrying the backpack, so that the user is not likely to have a hunchback. However, when the backpack of this structure is carried, the soft protrusions on the back of the backpack body always closely fit the back of the human body, so that the friction heat generated by the back of the human body and the backpack cannot be discharged, thereby causing the user's back to sweat and soak the clothes, thereby affecting the user's health, especially in hot summer.

[0003] Therefore need a kind of backpack that reduces carrying pressure and is breathable. Utility Model Content

[0004] In order to reduce the back pressure and improve the back air permeability, this patent provides the following technical solutions:

[0005] A first aspect: A lightweight and breathable backpack is provided, comprising a backpack body, a back panel and shoulder straps. The back panel and the backpack body are integrally formed, and the back panel fits the back when carried. The adjustable connection between the back panel and the shoulder straps can reduce the force exerted by the backpack body on the human back. The back panel has a raised structure for relieving the carrying pressure and a tree-shaped ventilation airflow channel.

[0006] Furthermore, a weight-bearing plate is provided inside the back plate, and the back plate includes a shoulder pad, a back pad and a waist support. The shoulder pad and the waist support are raised structures, and there is a gap between the shoulder pad and the waist support.

[0007] Furthermore, the shoulder pad is divided into an upper shoulder pad and a lower shoulder pad by means of indentation.

[0008] Furthermore, the lumbar support is of an outward-expanding style, which increases the area of ​​the lumbar support in contact with the waist so as to enhance the protection of the waist.

[0009] Furthermore, a back pad is arranged in the middle of the back plate, and a plastic weight-bearing strip is arranged inside the back pad.

[0010] This patent has the following beneficial effects:

[0011] 1. This patent discloses a lightweight and breathable backpack, including a backpack body, a backboard and shoulder straps. The backboard and the backpack body are integrally formed, and a weight-bearing plate is provided inside the backboard. The backboard fits the back when the backpack is carried, and the adjustable connection between the backboard and the shoulder straps can reduce the force exerted by the backpack body on the back of the human body. The backboard includes a shoulder pad, a back pad and a lumbar support. The back pad is arranged in the middle of the backboard, and a plastic weight-bearing strip is provided inside the back pad to form a gravity-assisted force distribution effect along the human-machine force point of the spine. The weight-bearing strip inside the back pad and the weight-bearing plate inside the backboard are combined to form a dynamic human-machine weight-bearing effect on the spine and the shoulder blade area on both sides, providing support for the back while maintaining the comfort of the backpack when carried. The cooperation of the shoulder pad and the shoulder strap can form a semi-circular force-bearing state, thereby reducing the carrying pressure of the backpack body on the human back.

[0012] 2. There is a height difference between the raised shoulder pads on both sides and the back pad. There is a gap between the single-side shoulder pad and the waist support for airflow exchange. The shoulder pads are indented so that there is a gap between the upper and lower shoulder pads for airflow exchange. The height difference and the gap form an airflow exchange channel. The airflow channel is shaped like a tree structure. The airflow channel with a tree structure can dissipate heat when the backpack is carried, making it cool and breathable.

[0013] 3. According to the principles of ergonomics, the position, structure, shape and size of the shoulder pad, back pad and waist support can reduce the pressure of the backpack body on the back when people are carrying the backpack. The shoulder pad is at the end of the stress point of the shoulder blade on the back of the human body, and the shoulder pad is divided into an upper shoulder pad and a lower shoulder pad by indentation. The waist support style is outward expansion, which increases the area of ​​the waist support contacting the waist to enhance the protection of the waist. The upper end of the shoulder pad is integrally formed with the starting section of the shoulder strap. When carrying the backpack, the upper end of the shoulder pad fits the stress point of the shoulder blade on the back, and the rear section of the shoulder strap is adjustable and connected to the waist support.

[0014] 4. In addition to reducing the pressure of the backpack body on the back and forming a tree-like airflow channel to disperse the heat generated by the friction between the back and the backboard when carrying the backpack, this patent also has good support. A weight-bearing plate is provided inside the backboard to provide strong support for the back of the backpack. At the same time, a plastic weight-bearing strip is provided inside the back pad to extend the human-machine force point of the spine to form a gravity-assisted force distribution effect.

[0026] The detailed features and advantages of this patent are described in detail in the specific implementation method below, and the content is sufficient to enable any technical personnel in this field to understand the technical content of this patent and implement it accordingly. According to the description, claims and drawings disclosed in this specification, technical personnel in this field can easily understand the relevant purposes and advantages of this patent.

[0027] In order to make the purpose, technical solutions and advantages of this patent clearer, the implementation method of this patent will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, it can be seen from the top perspective schematic diagram of a lightweight breathable backpack of this embodiment that it includes a backpack body 100, a back plate 200 and shoulder straps 300. The back plate 200 is arranged behind the backpack body 100 and is cut and formed integrally with the backpack body 100. The starting section of the shoulder straps 300 is symmetrically arranged on the upper part of the back plate 200, and the fixed end of the shoulder straps 300 is symmetrically arranged on the lower part of the back plate 200. A weight plate is arranged inside the back plate 200. The back plate 200 contacts a large area of ​​the back of the human body in the carrying state. The adjustable connection between the back plate 200 and the shoulder straps 300 can reduce the force of the backpack body 100 on the back of the human body.

[0029] like Figure 2As shown, the backboard 200 includes a shoulder pad 210, a back pad 220 and a waist support 230. The shoulder pad 210 and the waist support 230 are convex structures symmetrically distributed on both sides of the backboard 200, wherein the shoulder pad 210 occupies most of the area of ​​the backboard 200, and the waist support 230 is arranged below the shoulder pad 210, and there is a gap between the single-sided shoulder pad 210 and the waist support 230. The shoulder pad 210 is at the end of the stress point of the shoulder blade on the back of the human body, and the shoulder pad 210 is divided into an upper shoulder pad 210 and a lower shoulder pad 210 by indentation. The waist support 230 is an outward expansion type, and the protection of the waist is enhanced by increasing the area of ​​the waist support 230 contacting the waist. The upper end of the shoulder pad 210 is integrally formed with the starting section of the shoulder strap 300. When the shoulder is carried, the upper end of the shoulder pad 210 fits the stress point of the shoulder blade on the back, and the rear section of the shoulder strap 300 is adjustably connected to the waist support 230. The shoulder pad 210 and the shoulder strap 300 cooperate to form a semi-circular force-bearing state, thereby reducing the pressure of the backpack body on the back of the human body. A long strip of back pad 220 is provided in the middle of the backboard 200, and a plastic weight-bearing strip is provided inside the back pad 220, which extends along the human-machine force point of the spine to form a gravity-assisted force distribution effect. The weight-bearing strip inside the back pad 220 and the weight-bearing plate inside the backboard 200 form a dynamic human-machine weight-bearing effect on the spine and the shoulder blade area on both sides, providing support for the back while maintaining the comfort of the backpack when carrying it.

[0030] like Figure 3 As shown, it is the airflow channel formed by the back plate 200 and the back of the human body in the backpack state. There is a height difference between the raised shoulder pads 210 on both sides and the back pad 220. There is a gap between the single-sided shoulder pad 210 and the waist support 230 for airflow exchange. The shoulder pad 210 has an indentation so that there is a gap between the upper shoulder pad and the lower shoulder pad for airflow exchange. The height difference and the gap form an airflow exchange channel, and the airflow channel is shaped like a tree structure. When the backpack is carried, the back of the human body is completely in contact with the shoulder pad 210 and is completely not in contact with the back pad 220. The waist of the human body is partially supported by the waist support 230. The airflow enters from the gap opening formed by the shoulder pad 210 and the back pad 220 at the top of the backpack, and diffuses to the external environment along the back pad 220 to the indentation gap and the gap between the shoulder pad 210 and the waist support 230. When a person walks with the backpack on his back, the pressure and friction of the backpack body on the shoulder blades and back generate a lot of heat. The heat cannot dissipate, which causes sweat on the back. The air flow channels with a tree-like structure can dissipate heat when the backpack is on the back, making it cool and breathable.

[0031] In the specification of this patent, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various example structural parts and components of this patent, but these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the drawings. Since the embodiments disclosed in this patent can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this patent will not further describe various possible combinations.

[0033] In addition, the various implementation methods of this patent can be combined arbitrarily, as long as they do not violate the concept of this patent, they should also be regarded as the contents disclosed by this patent.
