Description

Technical Field

[0001] The present invention relates to the technical field of weight-reducing backpacks, and specifically to a back-carrying structure with a suspension weight-reducing function. Background Art

[0002] In many scenarios such as daily life, outdoor sports, and military operations, a large number of items are carried by backpacks. Among them, the more commonly used type of backpack is the double-shoulder backpack, and the weight of the items is transmitted to the human body through parts such as shoulder straps and the waist.

[0003] The back-carrying structure of traditional double-shoulder backpacks is mainly sewn by a backpack body that can hold items and two shoulder straps. When the carried items are heavy, the concentrated pressure will cause a greater burden on the shoulders, back, and waist. Carrying for a long time is extremely likely to cause muscle fatigue, soreness, and even injury. Therefore, backpacks with suspension weight reduction have been developed in the market.

[0004] For most of the suspension weight-reducing backpacks in the market, their structural design mainly uses lightweight metal support rails with rollers and springs. When the backpack is loaded, the spring compresses and stores energy, and when walking, the spring releases energy to offset the vertical impact force. However, for the backpack designed in this way, since its backpack body is connected through exposed metal supports and is only connected by rollers and springs, its stability is poor when walking. At the same time, the suspension weight-reducing force cannot be freely adjusted according to the needs. Moreover, when the body is tilted and outdoor climbing activities are carried out, it cannot adaptively change its suspension weight-reducing state according to the change of walking posture, resulting in a poor practical experience effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a back-carrying structure with a suspension weight-reducing function to solve the problems raised in the background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A back-carrying structure with a suspension weight-reducing function, including shoulder straps, a backpack body is arranged on one side of the shoulder straps, and a suspension weight-reducing mechanism is fixedly installed between the shoulder straps and the backpack body;

[0007] The suspension weight-reducing mechanism includes a load-bearing bracket, a frame, an elastic mechanism, a guiding component, and a partition. A load-bearing bracket is fixedly connected to the side of the shoulder strap close to the backpack body, a frame is fixedly connected to the side of the load-bearing bracket close to the backpack body, an elastic mechanism and a guiding component are fixedly installed inside the frame, and a partition is fixedly connected to the side of the frame away from the shoulder strap;

[0008] The elastic mechanism includes a bracket, a bottom shell, a first spring, and a top shell. A bracket is fixedly connected to the inner side of the frame. A bottom shell is fixedly connected to the upper side of the bracket. The upper side of the bottom shell is sleeved with evenly distributed first springs. The upper side of the first springs is sleeved with a top shell;

[0009] The load-bearing bracket can support the weight of the backpack. Through the cooperation between the frame, the elastic mechanism, and the guiding component, the backpack can be stably suspended and the weight can be reduced.

[0010] The items in the backpack are pulled by pulling the partition board. Since the partition board is fixedly connected to the moving frame, the moving frame is pulled accordingly. The moving frame compresses the first spring arranged between the top shell and the bottom shell through the connecting support plate. When walking, the first spring releases energy to offset the impact force in the vertical direction, so that during walking, the moving frame and the connecting frame slide up and down on the guide rail plate through the rollers, thereby achieving the purpose of weight reduction by suspension.

[0011] Furthermore, the load-bearing bracket includes a back panel, an X-shaped support plate, a cover plate, and a connecting head. A back panel is fixedly connected to the side of the shoulder strap close to the backpack body. An X-shaped support plate is fixedly connected to the inner side of the back panel. Evenly distributed connecting heads are fixedly connected to the side of the X-shaped support plate close to the backpack body. A cover plate is snap-connected to the side of the connecting head close to the backpack body.

[0012] Furthermore, the frame includes a fixed frame, a guide rail plate, a moving frame, rollers, and a connecting frame. A fixed frame is fixedly connected to the side of the cover plate close to the backpack body. A guide rail plate is fixedly connected to the inner side of the fixed frame. Rollers are arranged on the inner side of the guide rail plate. A connecting frame is fixedly connected to the side of the roller close to the center of the fixed frame. A moving frame is fixedly connected to the side of the connecting frame close to the backpack body. The rollers slide on the inner side of the guide rail plate. The X-shaped support plate is made of a lightweight metal material, such as aluminum alloy.

[0013] Furthermore, the guiding component includes a fixed block, a guiding column, and a connecting block. A fixed block is fixedly connected to the outside of the bottom shell. A guiding column is fixedly connected to the upper side of the fixed block. A connecting block is sleeved on the outer side of the upper part of the guiding column. The connecting block is fixedly connected to the top shell;

[0014] The partition board includes a separating board and a fabric interlayer. A separating board is fixedly connected to the side of the moving frame close to the backpack body. A fabric interlayer is fixedly connected to the inner side of the lower part of the separating board.

[0015] Further, a hinge assembly is provided inside the suspension weight reduction mechanism. The hinge assembly includes a fixed seat, a hinge group, a spherical rod, a connecting seat, and an orbital plate. One side of the cover plate close to the backpack body is fixedly connected with an orbital plate. Uniformly distributed spherical rods are slidably connected inside the orbital plate. One side of the spherical rod close to the backpack body is rotatably connected with a hinge group. The upper side of the hinge group is rotatably connected with a fixed seat, and the lower side of the hinge group is rotatably connected with a connecting seat. The connecting seat is fixedly connected with the top shell, and the fixed seat is fixedly connected with the inner side wall of the fixed frame.

[0016] During the process of the backpack body moving up and down for suspension weight reduction under the action of the moving frame and the connecting frame, since the hinge group is connected with the damper, and the upper end of the hinge group is fixedly connected with the inner side wall of the fixed frame and the lower end is fixedly connected with the top shell, the spring drives the hinge group to synchronously elongate and shorten while being compressed and released. Since the hinge group slides inside the orbital plate through a plurality of spherical rods, the height stability of the backpack body during the up and down movement is ensured.

[0017] Further, a damper is provided in the middle of the hinge assembly. The damper includes a connecting rod one, a sliding rod, a spring two, a fixed rod, a gear two, and a connecting rod two. One side of the lower part of the hinge group close to the backpack body is rotatably connected with a connecting rod one. One side of the middle part of the connecting rod one close to the shoulder strap is rotatably connected with a sliding rod. A fixed rod is sleeved on the outer side of the upper part of the sliding rod. The upper side of the fixed rod is rotatably connected with a connecting rod two. The connecting rod two is rotatably connected with the hinge group. Threads are provided on the outer side of the fixed rod and are threadedly connected with a gear two. A spring two is provided between the gear two and the sliding rod.

[0018] Further, a regulation assembly is provided on the outer side of the damper. The regulation assembly includes a knob, a fixing plate one, a fixing plate two, an annular block, a rotating shaft, and a gear one. The outer side of the gear two is engaged with a gear one. The upper side of the gear one is fixedly connected with a rotating shaft. The upper side of the rotating shaft is fixedly connected with an annular block. The upper side of the annular block is fixedly connected with a knob. The upper side of the fixed frame is fixedly connected with a fixing plate one and a fixing plate two. Grooves corresponding to the annular block are provided inside the fixing plate one and the fixing plate two. The fixing plate two is fixedly connected with the fixing plate one.

[0019] Since the upper end of the second spring is fixed to the second gear and the lower end is fixed to the sliding rod, it has the effect of the second-stage spring suspension and weight reduction. Moreover, when the user adjusts according to their own needs and preferences, by rotating the knob, the knob drives the annular block, the rotating shaft, and the first gear to rotate synchronously. While the first gear rotates, it meshes with and drives the second gear to rotate. Since the outer side of the fixed rod is provided with threads and the second gear is threadedly connected, the second gear moves upward or downward while rotating, thereby realizing the adjustment of the spring force of the second spring to increase or decrease, achieving the effect of freely controlling the suspension and weight reduction force;

[0020] Furthermore, both sides of the lower part of the cover plate are fixedly connected with adaptation components. The adaptation components include mounting plates, first adaptation rods, second adaptation rods, mounting blocks, and track seats. Both sides of the lower part of the bracket are fixedly connected with mounting plates. One side of the mounting plate close to the backpack body is fixedly connected with a track seat. The upper end of the track seat is rotatably connected with a first adaptation rod. The middle part of the first adaptation rod is rotatably connected with a second adaptation rod. A chute is opened inside the track seat. One end of the second adaptation rod slides in the chute and is rotatably connected with a mounting block. The upper side of the mounting block is fixedly connected with the top shell.

[0021] When the user tilts the body during outdoor climbing activities, the weight of the items in the backpack acts on the back. The items exert pressure on the first adaptation rod and the second adaptation rod through the fabric partition layer, causing the first adaptation rod and the second adaptation rod to rotate. Then, under the guiding action of the chute in the track seat, the second adaptation rod drives the mounting block to compress the first spring through the top shell, reducing the movement amplitude of the backpack and avoiding affecting climbing due to excessive movement amplitude of the backpack, achieving the purpose of adaptively adjusting the suspension and weight reduction state according to the walking posture.

[0022] Furthermore, a connecting support plate is fixedly connected between the moving frame and the top shell, and the moving frame can slide up and down.

[0023] Furthermore, the side of the partition plate away from the shoulder strap is fixed to the backpack body. The fabric partition layer is made of wear-resistant fabric, which can be one of nylon, polyester, canvas, and oxford cloth.

[0024] Compared with the prior art, the present invention provides a load-bearing structure with a suspension and weight reduction function, having the following beneficial effects:

[0025] 1. For the load-bearing structure with the suspension and weight reduction function, through the cooperation of the load-bearing bracket, the back plate, the X-shaped support plate, the cover plate, and the connecting head, the metal bracket can be hidden inside. At the same time, the X-shaped support plate evenly disperses the pressure of the backpack by using the evenly distributed fulcrums of the connecting head. At the same time, through the combination of the fixed frame, the moving frame, and the connecting frame, the existing suspension and weight reduction method with the metal bracket exposed is changed, significantly reducing the loss of the metal bracket and improving the comfort of the user when carrying the backpack.

[0026] 2. The backpack structure with the function of suspension and weight reduction enables the spring to drive the hinge group to synchronously elongate and shorten during compression and release through the cooperation among the frame, the elastic mechanism, the guiding component, and the hinge component. Since the hinge group slides inside the track plate through several spherical rods, the height stability of the backpack body during the up-and-down movement is ensured, changing the existing connection method that only uses a roller spring, which results in poor stability during walking.

[0027] 2. The backpack structure with the function of suspension and weight reduction enables the second-stage spring suspension and weight reduction effect through the cooperation among the regulation component, the damper, and the adaptation component. At the same time, the spring force of the second spring can be increased or decreased according to personal preferences, achieving the effect of freely regulating the suspension and weight reduction force. Moreover, when the walking posture changes to an inclined state, the second adaptation rod drives the installation block to compress the first spring through the sliding of the chute in the track seat under the guiding action, reducing the movement amplitude of the backpack and avoiding affecting climbing due to excessive movement amplitude of the backpack, achieving the purpose of self-adaptively adjusting the suspension and weight reduction state according to the walking posture, and making the practical experience effect better.

[0043] The suspension weight reduction mechanism 2 includes a load-bearing bracket 21, a frame 22, an elastic mechanism 23, a guiding component 24, and a partition plate 25. One side of the shoulder strap 1 close to the backpack body 3 is fixedly connected with the load-bearing bracket 21. One side of the load-bearing bracket 21 close to the backpack body 3 is fixedly connected with the frame 22. The elastic mechanism 23 and the guiding component 24 are fixedly installed inside the frame 22. One side of the frame 22 away from the shoulder strap 1 is fixedly connected with the partition plate 25;

[0044] The elastic mechanism 23 includes a bracket 231, a bottom shell 232, a first spring 233, and a top shell 234. The bracket 231 is fixedly connected inside the frame 22.

The top shell 234 is sleeved on the upper side of the first springs 233;

[0045] The load-bearing bracket 21 can support the weight of the backpack. Through the cooperation between the frame 22, the elastic mechanism 23, and the guiding component 24, the backpack can be stably suspended and the weight can be reduced.

[0046] The items in the backpack pull the partition plate 25. Since the partition plate 25 is fixedly connected to the moving frame 223, the moving frame 223 is pulled accordingly. The moving frame 223 compresses the first spring 233 arranged between the top shell 234 and the bottom shell 232 through the connecting support plate 4. When walking, the first spring 233 releases energy to offset the impact force in the vertical direction, so that during walking, the moving frame 223 and the connecting frame 225 slide up and down on the guide rail plate 222 through the rollers 224, thus achieving the purpose of weight reduction by suspension.

[0047] Furthermore, the load-bearing bracket 21 includes a back plate 211, an X-shaped support plate 212, a cover plate 213, and a connecting head 214. One side of the shoulder strap 1 close to the backpack body 3 is fixedly connected with the back plate 211. The X-shaped support plate 212 is fixedly connected to the inner side of the back plate 211. The evenly distributed connecting heads 214 are fixedly connected to one side of the X-shaped support plate 212 close to the backpack body 3. The cover plate 213 is clamped to one side of the connecting head 214 close to the backpack body 3.

[0048] Furthermore, the frame 22 includes a fixed frame 221, a guide rail plate 222, a moving frame 223, rollers 224, and a connecting frame 225. One side of the cover plate 213 close to the backpack body 3 is fixedly connected with the fixed frame 221. The guide rail plate 222 is fixedly connected to the inner side of the fixed frame 221.

The connecting block 243 is sleeved on the outer side of the upper part of the guiding column 242. The connecting block 243 is fixedly connected to the top shell 234.

[0050] The partition 25 includes a partition plate 251 and a fabric interlayer 252. The partition plate 251 is fixedly connected to the side of the moving frame 223 close to the backpack body 3. The fabric interlayer 252 is fixedly connected to the inner side of the lower part of the partition plate 251.

[0051] Further, a hinge assembly 5 is arranged inside the suspension weight reduction mechanism 2. The hinge assembly 5 includes a fixed seat 51, a hinge group 52, a spherical rod 53, a connecting seat 54, and an orbital plate 55. The orbital plate 55 is fixedly connected to the side of the cover plate 213 close to the backpack body 3. The evenly distributed spherical rods 53 are slidably connected to the inner side of the orbital plate 55. The hinge group 52 is rotatably connected to the side of the spherical rod 53 close to the backpack body 3. The fixed seat 51 is rotatably connected to the upper side of the hinge group 52. The connecting seat 54 is rotatably connected to the lower side of the hinge group 52. The connecting seat 54 is fixedly connected to the top shell 234. The fixed seat 51 is fixedly connected to the inner side wall of the fixed frame 221.

[0052] During the process of the backpack body 3 moving up and down for suspension weight reduction under the action of the moving frame 223 and the connecting frame 225, since the hinge group 52 is connected to the damper 7, and the upper end of the hinge group 52 is fixedly connected to the inner side wall of the fixed frame 221 and the lower end is fixedly connected to the top shell 234, the spring drives the hinge group 52 to be synchronously stretched and shortened while being compressed and released. Since the hinge group 52 slides inside the orbital plate 55 through a plurality of spherical rods 53, the height stability of the backpack body 3 during the up and down movement is ensured.

[0053] Further, a damper 7 is arranged in the middle of the hinge assembly 5. The damper 7 includes a first connecting rod 71, a sliding rod 72, a second spring 73, a fixed rod 74, a second gear 75, and a second connecting rod 76. The first connecting rod 71 is rotatably connected to the side of the lower part of the hinge group 52 close to the backpack body 3. The sliding rod 72 is rotatably connected to the side of the middle part of the first connecting rod 71 close to the shoulder strap 1. The second spring 73 is sleeved on the outer side of the upper part of the sliding rod 72. The fixed rod 74 is rotatably connected to the upper side of the sliding rod 72. The second connecting rod 76 is rotatably connected to the fixed rod 74. The outer side of the fixed rod 74 is provided with threads and is threadedly connected to the second gear 75. A second spring 73 is arranged between the second gear 75 and the sliding rod 72.

[0054] Further, a regulation component 6 is arranged outside the damper 7. The regulation component 6 includes a knob 61, a first fixing plate 62, a second fixing plate 63, an annular block 64, a rotating shaft 65, and a first gear 66. A first gear 66 is meshed with the outside of a second gear 75. The upper side of the first gear 66 is fixedly connected to a rotating shaft 65. The upper side of the rotating shaft 65 is fixedly connected to an annular block 64. The upper side of the annular block 64 is fixedly connected to a knob 61. The upper side of the fixing frame 221 is fixedly connected to a first fixing plate 62 and a second fixing plate 63. Grooves corresponding to the annular block 64 are formed inside the first fixing plate 62 and the second fixing plate 63. The second fixing plate 63 is fixedly connected to the first fixing plate 62.

[0055] Since the upper end of the second spring 73 is fixed to the second gear 75 and the lower end is fixed to the sliding rod 72, it has the effect of double spring suspension and weight reduction. Moreover, when the user adjusts according to their own needs and preferences, by rotating the knob 61, the knob 61 drives the annular block 64, the rotating shaft 65, and the first gear 66 to rotate synchronously. While the first gear 66 is rotating, it meshes with and drives the second gear 75 to rotate. Since threads are provided on the outside of the fixed rod 74 and the second gear 75 is threadedly connected thereto, the second gear 75 moves upward or downward while rotating, thereby realizing the adjustment of increasing or decreasing the spring force of the second spring 73, achieving the effect of freely regulating the suspension and weight reduction force.

[0056] Further, adaptation components 8 are fixedly connected to both lower sides of the cover plate 213. The adaptation components 8 include mounting plates 81, first adaptation rods 82, second adaptation rods 83, mounting blocks 84, and track seats 85. Mounting plates 81 are fixedly connected to both lower sides of the bracket 231. A track seat 85 is fixedly connected to one side of the mounting plate 81 close to the backpack body 3. The upper end of the track seat 85 is rotatably connected to a first adaptation rod 82. The middle part of the first adaptation rod 82 is rotatably connected to a second adaptation rod 83. A chute is formed inside the track seat 85. One end of the second adaptation rod 83 slides in the chute and is rotatably connected to a mounting block 84. The upper side of the mounting block 84 is fixedly connected to the top shell 234.

[0057] When the user tilts the body during outdoor climbing activities, the weight of the items in the backpack acts on the back. The items apply pressure to the first adaptation rod 82 and the second adaptation rod 83 through the fabric partition layer 252, causing the first adaptation rod 82 and the second adaptation rod 83 to rotate. Then, under the guiding action of the chute inside the track seat 85, the second adaptation rod 83 drives the mounting block 84 to compress the first spring 233 through the top shell 234, reducing the movement amplitude of the backpack and avoiding the influence on climbing due to excessive movement amplitude of the backpack, achieving the purpose of adaptively adjusting the suspension and weight reduction state according to the walking posture.

[0058] Further, a connecting support plate 4 is fixedly connected between the moving frame 223 and the top shell 234, and the moving frame 223 can slide up and down.

[0059] Furthermore, the side of the partition plate 251 away from the shoulder strap 1 is fixed to the backpack body 3. The fabric compartment 252 is made of wear-resistant fabric, which can be one of nylon, polyester, canvas, and oxford cloth.

[0060] Specific usage method and function of this embodiment:

[0061] When in use, first carry the entire backpack through the shoulder strap 1. The backpack body 3 contains items. Since the backpack's movable parts can be combined into a whole through the fixed frame 221, movable frame 223, and connecting frame 225;

[0062] When the user walks freely with the backpack on the back, the items in the backpack pull the partition plate 25. Since the partition plate 25 is fixedly connected to the movable frame 223, the movable frame 223 is pulled accordingly. The movable frame 223 compresses the first spring 233 disposed between the top shell 234 and the bottom shell 232 through the connecting support plate 4. When walking, the first spring 233 releases energy to offset the impact force in the vertical direction, so that during the walking process, the movable frame 223 and the connecting frame 225 slide up and down on the guide rail plate 222 through the rollers 224, thereby achieving the purpose of suspended weight reduction.

[0063] During the process of the backpack body 3 moving up and down for suspended weight reduction under the action of the movable frame 223 and the connecting frame 225, since the hinge group 52 is connected to the damper 7, and the upper end of the hinge group 52 is fixedly connected to the inner side wall of the fixed frame 221 and the lower end is fixedly connected to the top shell 234, the spring drives the hinge group 52 to synchronously elongate and shorten during compression and release. Since the hinge group 52 slides inside the track plate 55 through a plurality of spherical rods 53, the height stability of the backpack body 3 during the up and down movement process is ensured;

[0064] At the same time, since the upper end of the second spring 73 is fixedly connected to the second gear 75 and the lower end is fixedly connected to the sliding rod 72, the effect of double-spring suspended weight reduction is achieved. Moreover, when the user can rotate the knob 61 according to their own needs and preferences, the knob 61 drives the annular block 64, the rotating shaft 65, and the first gear 66 to rotate synchronously. While the first gear 66 rotates, it meshes with and drives the second gear 75 to rotate. Since the outer side of the fixed rod 74 is provided with threads and is threadedly connected to the second gear 75, the second gear 75 moves upward or downward while rotating, thereby achieving the effect of increasing or decreasing the spring force of the second spring 73 and achieving the effect of freely adjusting the suspended weight reduction intensity;

[0065] When the user tilts the body and engages in outdoor climbing activities, the weight of the items in the backpack acts on the back. The items exert pressure on the first adaptation rod 82 and the second adaptation rod 83 through the fabric partition layer 252, causing the first adaptation rod 82 and the second adaptation rod 83 to rotate. Then, under the guiding action of the sliding groove in the track base 85, the second adaptation rod 83 drives the mounting block 84 to compress the first spring 233 through the top shell 234, reducing the movement amplitude of the backpack and avoiding affecting climbing due to excessive movement amplitude of the backpack, thus achieving the purpose of adaptively adjusting the suspended weight reduction state according to the walking posture.

[0066] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
