DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Figure 1 The structure diagram of the backpack bracket in the utility model is shown. Figure 2 A side view of the backpack support in the utility model is shown. Figure 3The front view of the backpack bracket in the utility model is shown, and the backpack bracket includes: a bracket body 100, the bracket body 100 includes a bracket body front side 101 and a bracket body back side 102, the bracket body front side 101 is used to contact the back of the human body; the bracket body front side 101 is recessed toward the bracket body back side 102 to form a first groove 1 that fits the back; the upper end of the bracket body 100 has an arc groove 2 recessed toward the back side of the bracket body 100; the lower end of the bracket body 100 is bent toward the bracket body front side 101 to form a curved surface 3.
[0028] The first groove 1 is used to wrap the back and strengthen the support strength of the entire carbon plate, so that the bracket body 100 can maximize the user's head movement space, avoid being blocked by the backpack when raising the head and affecting the user's field of vision, and can bring a sense of security to the user. In addition, the bracket body 100 can fit the shape of the spine, making the backpack bracket ergonomic, reducing the gap between the bracket body 100 and the back, enhancing the wrapping, bringing the center of gravity closer to the back of the human body, and efficiently transferring and dispersing gravity. The first groove 1 strengthens the support strength of the bracket body 100 and greatly reduces the deformation of the bracket body 100 under overload conditions, which affects the carrying experience. In addition, the first groove 1 can balance the gravity of the backpack and transfer the weight to other places, reducing the risk of wear and tear of the spine caused by greater force, which is beneficial to protecting the safety and health of the user. The arc groove 2 is used to provide a certain amount of space for the back of the human head to move, which can reduce the risk of obstructed vision when looking up during the carrying process, and prevent the back of the head from directly colliding with hard objects or the ground when the user falls. The arc groove 2 can buffer the force of the back of the human head colliding with hard objects or the ground, reduce brain damage, and help improve the safety and health of the user. The lower end of the bracket body 100 is bent toward the bracket body 100. The front side 101 of the bracket body forms a curved surface 3. The curved surface 3 is combined with the physiological curve of the human body and fits the position of the human waist, so that the bracket body 100 can better wrap the human body, improve the carrying comfort performance and gravity transfer efficiency, and thus reduce the load on the shoulders and back.
[0029] Furthermore, at least one multi-deformable hole 11 is provided in the first groove 1, and at least one multi-deformable hole 11 is distributed in the middle area of the first groove 1 according to a preset position. In this embodiment, seven multi-deformable holes 11 are provided in the first groove 1, and the seven multi-deformable holes 11 include two triangular holes 111, two quadrilateral holes 112, two short hexagonal holes 114 and one long hexagonal hole 113. The long hexagonal hole 113 is located at the center of the first groove 1, the two short hexagons are respectively located at the upper and lower ends of the long hexagon, the two quadrilateral holes 112 are distributed on the left and right sides of the long hexagonal hole 113, and the two triangles are located on the left and right sides of the long hexagonal hole 113. The function of the seven deformable holes 11 is to buffer the stress on the bracket body 100. When the bracket body 100 is subjected to force, appropriate bending can buffer the force on the bracket body 100, thereby improving the structural strength of the bracket body 100. Secondly, the plurality of deformable holes reduce the weight of the bracket body 100 without changing the structural strength of the bracket body 100, thereby reducing the weight of the backpack to a certain extent, reducing the weight that climbers have to carry, and helping to preserve the physical strength of climbers.
[0030] Furthermore, more than one fixing hole 12 is provided on the side wall of the first groove 1. In the present embodiment, four fixing holes 12 are provided on the side wall of the first groove 1. The first groove 1 has two side walls, wherein two of the four fixing holes 12 are correspondingly provided on one of the two side walls. The four fixing holes 12 are used to fix the relative position relationship between the backpack and the support body, so as to avoid the backpack from shifting during use, so that the backpack's effect on the support body is biased to one side, resulting in the inability to transmit the force to the corresponding position. The four fixing holes are conducive to fixing the relative position between the backpack and the support body, and ensuring that the support body can effectively transmit the force to the corresponding position.
[0031] Furthermore, the two sides of the curved surface 3 are recessed toward the geometric center of the curved surface 3 to form a first arc 31 and a second arc 32. The first arc 31 and the second arc 32 are recessed toward the geometric center of the curved surface 3, that is, the apexes of the first arc 31 and the second arc 32 can both abut against the spine, ensuring that the lower end of the support body 100 can abut against the spine from three directions, which is beneficial for transferring the load to the human hip. Secondly, the curved surface 3 is designed with the first arc 31 and the second arc 32, which can also reduce the weight of the backpack support, reduce the weight of the backpack to a certain extent, reduce the weight that the climber has to carry, and is beneficial for preserving the physical strength of the climber.
[0032] Furthermore, the lower half of the first arc 31 extends outward to form a first pressure transfer plate 311, and the lower half of the second arc 32 extends outward to form a second pressure transfer plate 321, and the first pressure transfer plate 311 and the second pressure transfer plate 321 both have a certain curvature, the first pressure transfer plate 311 matches the curvature of the hip, and the second pressure transfer plate 321 matches the other curvature of the hip. When the user carries a heavy backpack, the first pressure transfer plate 311 and the second pressure transfer plate 321 can transfer part of the weight of the backpack to the hip of the human body, reducing the pressure of the backpack on the spine, so as to achieve the effect that part of the backpack's gravity acts on the back and the other part of the backpack's gravity acts on the hip, which is beneficial to apply gravity to various parts, thereby reducing the user's physical energy consumption.
[0033] Furthermore, the middle area of the curved surface 3 is recessed toward the back side of the bracket body 100 to form a second groove 33, and the second groove 33 is used to improve the mechanical strength of the curved surface 3. The side wall of the groove has a supporting force on the curved surface 3. When the curved surface 3 is subjected to an external force, the curved surface 3 will deform slightly toward the groove direction after being subjected to the external force. At this time, the side wall of the groove has a supporting force on the curved surface 3, ensuring that the deformation amplitude of the curved surface 3 after being subjected to the force is within a preset range, thereby avoiding the backpack bracket from bending due to the curved surface 3 being subjected to a large external force, which is beneficial to improving the mechanical strength of the backpack bracket.
[0034] refer to Figure 3 , the bottom of the second groove 33 is an isosceles trapezoid, the length of the upper base of the bottom of the second groove 33 close to the bottom end away from the bracket body 100 is D1, the lower base and upper base of the side of the bottom of the second groove 33 close to the bottom end of the bracket body 100 is D2, and the constraint relationship between D1 and D2 is: D1>D2. Since the bottom of the second groove 33 is an isosceles trapezoid, the gravity of the bracket body and the backpack is transmitted to the second groove 33, and the second groove 33 transmits the force to the first pressure transfer plate 311 and the second pressure transfer plate 321, and finally the first pressure transfer plate 311 and the second pressure transfer plate evenly exert the force on the human body.
[0035] Furthermore, the curved surface 3 is provided with one or more circular holes 34 and one or more elliptical holes 35. In this embodiment, the curved surface is provided with two circular holes and four elliptical holes, and the two circular holes are symmetrically distributed based on the second groove, and the four elliptical holes are symmetrically distributed based on the second groove. The circular holes 34 and the elliptical holes 35 are used to connect the backpack bracket with the backpack. More than one of the elliptical holes 35 have a certain curvature, and the backpack bracket is connected to the backpack based on a waist belt. The waist belt can move slightly in the corresponding elliptical holes, so that the waist belt can adjust the angle with the hips as the human body walks, maintain the relative neutrality of the backpack body, reduce the loss of left and right swing resistance, and make the human body more convenient in walking activities.
[0036] Specifically, the gravity of the bracket body and the backpack is transmitted to the second groove 33, and the second groove 33 transmits the force to the first pressure transfer plate 311 and the second pressure transfer plate 321, and the circular hole 35 and the elliptical hole 34 transmit the force they receive to the first pressure transfer plate 311 and the second pressure transfer plate 321, the first pressure transfer plate 311 and the second pressure transfer plate 321 transmit the force to the human hip and then transfer a large amount of weight to the human hip, reducing the risk of gravity concentrating on the shoulders and compressing the human spine, thereby reducing the damage to the user's spine and physical energy consumption caused by the weight.
[0037] Furthermore, the backpack bracket is made of carbon fiber. Carbon fiber has the characteristics of low density and light weight, and its strength is 4 to 5 times higher than that of steel. Therefore, the carbon fiber backpack bracket can greatly reduce the weight of the backpack while ensuring strength, reduce the weight of the mountaineers, and help preserve the physical strength of the mountaineers; carbon fiber has good thermal stability. Due to the small thermal expansion coefficient of carbon fiber, it will not burst even if it is suddenly cooled from high temperature, ensuring the stability of the backpack bracket under various temperature conditions.
[0038] Figure 4 The schematic diagram of the structure of the mountaineering backpack in the utility model is shown. The utility model also proposes a mountaineering backpack including the carrying system with the backpack bracket, the backpack body 200, the shoulder strap slide rail adjustment plate 400 and the dynamic waist belt 300. The backpack bracket in the carrying system with the backpack bracket is installed on the backpack body 200, the shoulder strap slide rail adjustment plate 400 is connected to the middle area of the backpack bracket, and the dynamic waist belt 300 is connected to the lower end of the backpack bracket. The shoulder strap slide rail adjustment plate 400 is adjusted according to the back length of the human body, so that the backpack carrying system is more suitable for the individual body shape; the connection part of the dynamic waist belt 300 and the backpack bracket 100 has a small range of mobility, and the dynamic waist belt 300 can adjust the angle as the human body walks, which is more convenient to move and reduces the loss of resistance.
[0039] Furthermore, the shoulder strap rail adjustment plate 400 is connected to the dynamic waist belt 300, and when driven by an external force, the shoulder strap rail adjustment plate 400 drives the dynamic waist belt 300 to move in the vertical direction relative to the backpack bracket. The shoulder strap rail adjustment plate 400 includes three gears, which are L gear, M gear and S gear. The L gear corresponds to users with longer backs, the M gear corresponds to users with medium backs, and the S gear corresponds to users with shorter backs. Users can adjust the gears according to their actual conditions to ensure that the mountaineering backpack is suitable for customers of various physiques.
[0040] The utility model is provided with a first groove on the backpack bracket to form a reinforcing rib, which greatly improves the supporting force of the backpack; the first groove fits closely with the human spine, and then the backpack bracket scientifically distributes the weight to multiple parts of the human body, so that the backpack bracket is ergonomic, realizes gravity transfer and easy load, improves the comfort of carrying, and reduces physical energy loss during hiking. The utility model is provided with an arc groove to provide a certain activity space for the back of the human head, which can reduce the risk of obstructed vision when looking up during the carrying process, and at the same time avoids the back of the head directly colliding with hard objects or the ground when the user falls, thereby reducing brain damage and helping to improve the safety and health of the user; the utility model is also provided with a curved surface, which is combined with the physiological curve of the human body and fits the position of the human waist dimple, so that the bracket body 100 can better wrap the human body, improve the carrying comfort performance and gravity transfer efficiency, and thus reduce the load on the shoulders and back.
