Description

Technical Field

[0001] The utility model belongs to the technical field of backpacks, and in particular relates to a bionic weight-bearing backpack. Background Art

[0002] Among the many types of equipment, load carriers, with their unique design and important functions, have become indispensable tools in many fields. Whether it's outdoor enthusiasts exploring mountains, rivers, lakes, or the oceans, or emergency rescue workers transporting supplies in emergencies, load carriers play a key role.

[0003] Due to design reasons, existing backpacks cannot effectively reduce the wearer's carrying fatigue during long-distance use, and their single-person load-bearing capacity is no different from that of ordinary backpacks.

[0004] Therefore, for the comfort and load capacity of the wearer, and based on ergonomics, a bionic load-bearing backpack is designed, which meets the requirements of light weight, uniform load, and ergonomics. It solves the wearer's carrying problem, can effectively relieve their carrying fatigue, improve the wearer's carrying capacity, and thus effectively improve the wearer's field performance and ensure the wearer's survival ability in the wild environment.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a bionic weight-bearing backpack.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A bionic load-bearing backpack, comprising a backpack body, connected to which are a harness assembly, a load-bearing system for fixing a load, a multifunctional waist seal, and a load-bearing connector, wherein the load-bearing connector is disposed in the middle of the bottom of the backpack body;

[0009] The back frame body is curved according to the biological curve of the human back and is provided with multiple sets of mounting holes from top to bottom for adjusting the height of the shoulder strap assembly and the position of the load-bearing system. Through its unique S-shaped structure design and the use of highly elastic materials, the bionic weight-bearing back frame can reduce the physical burden by 45% and over 70% when walking and standing, respectively.

[0010] The mounting holes include a first mounting hole group, a second mounting hole group, a third mounting hole group, a fourth mounting hole group, and a plurality of loading system mounting holes evenly arranged on the edge of the back frame body;

[0011] The harness assembly includes a shoulder strap, a tail strap, and a rear strap. Part of the shoulder strap is sewn to part of the back pad, and one end of the shoulder strap away from the sewn part is connected to the first mounting hole group, and one end of the back pad away from the shoulder strap is connected to the second mounting hole group and the third mounting hole group in sequence. The sewn end of the shoulder strap is also connected to the rear strap via a first buckle. When the back frame device needs to be unfastened, it is only necessary to unfasten the first buckle on the shoulder strap. The end of the rear strap away from the first buckle is connected to the load-bearing system mounting hole at the bottom side of the back frame body.

[0012] The multifunctional waist belt is detachably connected to the back frame body through a load-bearing connector. After carrying heavy objects, part of the gravity is transferred through the load-bearing connector to transmit the force to the waist position.

[0013] Specifically, the first mounting hole group, the second mounting hole group, the third mounting hole group, and the fourth mounting hole group are three horizontal through slots arranged vertically, and the load-bearing system mounting holes are vertical through slots; the three horizontal through slots correspond to the three adjustment gears S, M, and L, respectively. The S gear is suitable for 160-170 cm, the M gear is suitable for 170 cm-180 cm, and the L gear is suitable for 180 cm-190 cm to meet the carrying needs of different heights.

[0014] Furthermore, the shoulder strap is connected to the first mounting hole group through a hanging loop, and the back pad is connected to the second mounting hole group and the third mounting hole group through a hanging loop. The hanging loop can be adjusted in the three horizontal through slots of the first mounting hole group, the second mounting hole group, and the third mounting hole group according to people of different body shapes.

[0015] Furthermore, the load-bearing system includes a plurality of transverse fixing belts connected to the loading system mounting holes and used for transversely fixing the load, and the upper and lower parts of the backpack body are connected to a plurality of vertical fixing belts for vertically fixing the load.

[0016] Specifically, the part where the shoulder straps are sewn to the back pad is also slidably covered with a chest fixing strap for fixing the two shoulder straps, so that the shoulder straps can be firmly fixed to the body when a person walks quickly. The chest fixing strap includes two chest strap adjustment straps connected by a second buckle, and each chest strap adjustment strap is respectively connected to the shoulder strap.

[0017] Specifically, the back frame body is made of carbon fiber composite material.

[0018] Specifically, the side of the back pad close to the human body is made of breathable three-dimensional fabric, and an additional cushioning pad with grooves is provided to ensure comfort and breathability when worn, and to avoid stuffiness and discomfort.

[0019] Specifically, the main materials of the shoulder strap assembly, the load-bearing system and the multifunctional waist belt are all made of single-soldier 1.0 high-strength nylon filament flame-retardant camouflage coated fabric.

[0020] Specifically, the ends of the shoulder strap and the tail strap are both stored using Velcro.

[0021] Specifically, the shoulder strap is further provided with a shoulder strap adjustment belt for adjusting the distance between the back and the backpack body when carrying the backpack, and the shoulder strap and the shoulder strap adjustment belt are connected by a Japanese buckle.

[0022] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0023] This utility model designs the main body of the backpack into an S-shape according to the curve of the human body, which fits the back of the human body. This allows the bionic load-bearing backpack to reduce the physical burden by 45% and more than 70% when walking and standing respectively. The designed socket realizes a one-button quick-release function, which can quickly remove the carried equipment. The shoulder straps and back pads are made of three-dimensional fabric and built-in high-elasticity foam, which can relieve the pressure on the shoulders, back and waist when carrying. The shoulder straps and back pads are freely adjustable on the backpack body to meet the needs of people of different heights. The load-bearing system has an adjustable structure and is used in conjunction with spare accessories to achieve modular carrying of different types of equipment. It can be used in combination with multi-functional vests, lightweight multi-functional waist belts, etc. without interfering with each other. When carrying for long-term travel, the shoulders, waist, back and buttocks are balanced, meeting the adaptability requirements of high temperature, high humidity, salt fog, and high cold environments.
