Description

Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a backpack. Background Technology

[0002] Traditional backpacks generally have shortcomings in terms of shoulder strap pressure and heat dissipation, as well as back heat dissipation. The shoulder straps are mostly made of a single layer of fabric, which concentrates the pressure on the deltoid muscle area of ​​the shoulder. Wearing them for a long time can easily lead to poor blood circulation and soreness. The back of the backpack is sealed and airtight, which can cause sweat to accumulate and cause skin discomfort. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a backpack that improves the shoulder strap stress and heat dissipation and the back ventilation and heat dissipation.

[0004] To solve the aforementioned technical problems, the technical solution adopted by this utility model is: a backpack, including a bag body and shoulder straps provided on the bag body. The shoulder straps, from the outside to the inside, sequentially include a wear-resistant layer, a honeycomb shock-absorbing layer, a memory foam padding, and S-shaped guide strips, with a first guide groove formed between adjacent guide strips. The back of the bag body has two symmetrically distributed pad groups, with a second guide groove formed between the two pad groups, and the second guide groove is arranged longitudinally. The operating principle of this utility model is as follows: the S-shaped guide strips on the shoulder straps ensure heat dissipation and breathability while reducing pressure on the user's blood vessels; the honeycomb shock-absorbing layer disperses the user's vertical pressure; the second guide groove between the pad groups ensures breathability and heat dissipation between the user's back and the bag body, optimizing the user's experience.

[0005] As an improvement, the guide strip is arranged in an S-shape along the long axis of the shoulder strap, and the guide strip is made of silicone or rubber.

[0006] As an improvement, the pad assembly includes, from top to bottom, a first pad located at the top of the package body, a second pad located in the middle of the package body, and a third pad located at the bottom of the package body; a third flow channel is formed between the first pad and the second pad, and a fourth flow channel is formed between the second pad and the third pad; the third flow channel and the fourth flow channel are arranged laterally and communicate with the second flow channel.

[0007] As an improvement, the wear-resistant layer is made of high-density Oxford cloth.

[0008] As an improvement, the honeycomb damping layer is a TPU honeycomb array with a pore size of 3-5mm and a compression resilience of ≥90%.

[0009] The beneficial effects of this utility model are: the S-shaped guide strip on the shoulder strap ensures heat dissipation and breathability while reducing pressure on the user's blood vessels; the honeycomb shock-absorbing layer disperses the user's vertical pressure; the second, third, and fourth guide grooves between the pad groups are interconnected, ensuring breathability and heat dissipation between the user's back and the bag, and optimizing the user's experience.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] like Figure 1 , 2 As shown in Figure 3, a backpack includes a bag body 1 and a shoulder strap 3 disposed on the bag body 1. The shoulder strap 3 includes, from the outside to the inside, a wear-resistant layer 31, a honeycomb shock-absorbing layer 32, a memory foam padding 33, and an S-shaped airflow guide strip 34. The airflow guide strip 34 is arranged in an S-shape along the long axis of the shoulder strap 3, and a first airflow groove 341 is formed between adjacent airflow guide strips 34 to facilitate heat dissipation and ventilation. During use, the airflow guide strip 34 contacts the user's shoulder, reducing the user's stress area and thus reducing pressure on the user's blood vessels. The airflow guide strip 34 is made of silicone or rubber, with a soft and elastic texture to ensure a comfortable user experience. The memory foam padding 33 prevents the shoulder strap 3 from deforming; the honeycomb shock-absorbing layer 32 is a TPU honeycomb array with a pore size of 3-5mm and a compression rebound rate of ≥90%, which can disperse 30%-40% of the vertical pressure and optimize the user's experience; the wear-resistant layer 31 is made of high-density Oxford cloth, which ensures wear resistance while enhancing the breathability of the wear-resistant layer 31. The heat from the user's shoulder is dissipated sequentially through the first channel 341, the memory foam padding 33, the honeycomb shock-absorbing layer 32 and the high-density Oxford cloth, resulting in good breathability and heat dissipation.

[0016] like Figure 1As shown, the back of the bag body 1 is provided with two pad groups 2 symmetrically distributed from left to right. A second airflow channel 24 is formed between the two pad groups 2 in a longitudinal direction. The pad group 2 includes, from top to bottom, a first pad 21 at the upper part of the bag body 1, a second pad 22 in the middle part of the bag body 1, and a third pad 23 at the lower part of the bag body 1. The first pad 21 and the second pad 22 correspond to the user's back area and play a supporting and massaging role; the third pad 23 corresponds to the user's waist area and plays a supporting and massaging role. At the same time, a third airflow channel 25 is formed in a horizontal direction between the first pad 21 and the second pad 22, and a fourth airflow channel 26 is formed in a horizontal direction between the second pad 22 and the third pad 23. The third airflow channel 25 and the fourth airflow channel 26 are both connected to the second airflow channel 24 to enhance the airflow between the bag body 1 and the user's back, ensure its breathability and heat dissipation effect, and optimize the user's experience.

[0017] The working principle of this utility model is as follows: the S-shaped guide strip 34 on the shoulder strap 3 ensures heat dissipation and breathability while reducing pressure on the user's blood vessels; the honeycomb shock-absorbing layer 32 disperses the user's vertical pressure; the second guide groove 24, the third guide groove 25 and the fourth guide groove 26 between the pad block groups 2 are interconnected to ensure breathability and heat dissipation between the user's back and the bag body 1, and optimize the user's experience.
