Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to a light and breathable spine-protecting school bag. Background Art

[0002] A breathable backpack is a specially designed backpack that focuses on improving back ventilation, making it more comfortable for the wearer during exercise or when carried for extended periods. Breathable backpacks typically incorporate mesh materials, vents, or air circulation systems to increase back airflow and reduce sweat accumulation. Additionally, some breathable backpacks utilize lightweight materials, ergonomic designs, and multiple compartments to enhance carrying comfort and convenience.

[0003] Existing breathable backpack back pad designs mostly fit the entire back of the human body. The human spine supports most of the pressure when the human body moves. If the backpack fits the human spine, it will put more pressure on the spine. In addition, fitting the back of the human body will affect the discharge of heat and sweat in hot weather.

[0004] In order to address the above problems, a light and breathable spine-protecting school bag is urgently needed. Utility Model Content

[0005] The purpose of the present invention is to provide a light and breathable spine-protecting school bag to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, a lightweight, breathable, spine-protecting backpack is provided, comprising a backpack body and shoulder straps. The backpack body is provided with a back panel on its back, the back panel being able to adjust its curved structure according to the curve of the human back. The back panel has wavy protrusions and regularly arranged hollow openings on its surface, the openings being arranged in a mirror image with the human spine as the midline.

[0007] The back panel is composed of several gravity dispersion plates and a flexible plate. The gravity dispersion plates are evenly distributed on the left and right sides of the flexible plate. An air channel is formed between any two adjacent gravity dispersion plates, and a wave valley with a diversion function is formed between any two protrusions. The wave valley is connected with the opening and the air channel to form a ventilation channel. External air can contact the back of the human body through the ventilation channel to improve breathability and wearing comfort, avoid sweat accumulation and stuffiness, and avoid sweat accumulation and stuffiness. The hollow design of the ventilation channel can effectively reduce the weight of the backpack, making the backpack lighter and more comfortable, and more suitable for long-term use by students.

[0008] The gravity dispersion plate is sewn onto the flexible plate through a breathable mesh, and the breathable mesh also wraps the protrusions. The breathable mesh can prevent the flexible plate from directly contacting the back of the human body, and can prevent the wavy protrusions from causing a sense of squeezing on the back of the human body.

[0009] Furthermore, two sections of waist belt are provided at the bottom of the backpack body. The two sections of waist belt are movably connected by buckles and fastened around the waist of the human body. The buckles include a male buckle and a female buckle.

[0010] Furthermore, the flexible plate is made of EVA material, and the gravity dispersion plate is made of plastic material.

[0011] Furthermore, the gravity dispersion plates include a total of six, including one each on the upper and lower sides and two on the left and right sides. The air channels formed between the gravity dispersion plates are in the shape of an "*". The well-connected air channels can help the back of the human body ventilate faster, avoiding the accumulation of sweat and the feeling of stuffiness.

[0012] Furthermore, ventilation holes are provided on the shoulder strap near the human body's shoulders, and the material thereof is made of mesh.

[0013] Furthermore, the opening is in a teardrop-shaped structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This application adopts a combined design of a gravity dispersion plate and a flexible plate. The gravity dispersion plate can evenly distribute the pressure of the backpack to the left and right sides of the back, thereby reducing the pressure on the spine. At the same time, the air channels formed between the gravity dispersion plates can circulate with external wind from different directions to improve the breathability and heat dissipation of the back. The heat from the back can enter the air channels through the openings and be quickly dissipated, avoiding sweat accumulation and stuffiness.

[0016] At the same time, the hollow design of the ventilation channel can effectively reduce the weight of the backpack, making it lighter, increasing comfort, and more suitable for long-term use by students. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-4 As shown, a lightweight and breathable spine-protecting school bag is provided, comprising a school bag body 1 and a shoulder strap 2. The shoulder strap 2 is provided with ventilation holes near the human shoulder and is made of mesh. In this embodiment, the portion of the shoulder strap 2 away from the human shoulder is made of nylon woven belt. Adjustment buckles are provided on the nylon woven belt to adjust the length of the shoulder strap 2 according to the height of the human body. A back panel 3 is provided on the back of the school bag body 1. The back panel 3 can adjust its curve structure according to the curve of the human back. The surface of the back panel 3 is provided with wavy protrusions and regularly arranged hollow openings 4. The openings 4 are arranged with the human spine as the midline mirror image and have a teardrop-shaped structure.

[0026] The back panel 3 is composed of several gravity dispersion plates 301 and a flexible plate 302. The gravity dispersion plates 301 are evenly distributed on the left and right sides of the flexible plate 302. An air channel 5 is formed between any two adjacent gravity dispersion plates 301. A wave valley with a diversion function is formed between any two protrusions. The wave valley is connected with the opening 4 and the air channel 5 to form a ventilation channel. External air can contact the back of the human body through the ventilation channel to improve breathability and wearing comfort, avoid sweat accumulation and stuffiness, and avoid sweat accumulation and stuffiness. The hollow design of the ventilation channel can effectively reduce the weight of the backpack, making the backpack lighter and more comfortable, and more suitable for long-term use by students.

[0027] The gravity dispersion plate 301 is sewn onto the flexible plate 302 through a breathable mesh, and the breathable mesh also wraps the protrusions inside. The breathable mesh can prevent the flexible plate 302 from directly contacting the back of the human body, and can also prevent the wavy protrusions from forming a squeezing feeling on the back of the human body.
