Description

Technical Field

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

[0002] To address the issue of backpacks lacking effective back support, leading to back fatigue during long hikes or when carrying heavy loads, and potentially causing discomfort or injury due to insufficient support, some backpacks incorporate relatively lightweight back support components. These components are mostly aluminum strip support structures or curved plate structures. Aluminum strip support structures have a small support area, making it difficult to effectively distribute the backpack's weight across the body. Curved plate structures, on the other hand, have low strength and can only distribute the backpack's weight in localized areas, not across the entire back. In other words, both existing back support components offer unsatisfactory back support performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a back support component with good back support effect, and a backpack having the back support component.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a back support assembly, including a support plate and at least one rigid support strip, wherein the rigid support strip has an arc-shaped segment, the front wall surface of the rigid support strip is in contact with the support plate, and the support plate forms an arc-shaped contact area corresponding to the arc-shaped segment.

[0005] Furthermore, the support plate is a deformable thin plate.

[0006] Furthermore, the support plate is provided with a mounting cavity, and the rigid support strip is installed in the mounting cavity.

[0007] Furthermore, it also includes a webbing, which is connected to the support plate, and the webbing and the support plate enclose the mounting cavity.

[0008] Furthermore, the mounting cavity has an opening for taking out and placing the rigid support strip.

[0009] Furthermore, the webbing includes a fixed part and a blocking part connected together. The fixed part is fixedly connected to the support plate, and the blocking part is used to block the take-up and put-out port.

[0010] Furthermore, when the blocking part blocks the take-up and put-out port, the end of the blocking part away from the fixing part goes around the edge of the support plate and is placed on the side of the support plate away from the rigid support strip.

[0011] Furthermore, the shielding part is provided with a first Velcro strap, and the support plate is provided with a second Velcro strap that cooperates with the first Velcro strap.

[0012] To solve the above-mentioned technical problems, the present invention also adopts the following technical solution: a backpack, including a main body, on which the above-mentioned back support component is installed.

[0013] Furthermore, the back support assembly is detachably connected to the back panel of the main body.

[0014] The beneficial effects of this utility model are as follows: This backpack support assembly has a connected support plate and a rigid support strip. The support plate can make large-area contact with the user's back, thereby effectively distributing the weight of the backpack and avoiding discomfort to the user's back due to excessive local pressure. The rigid support strip can support the support plate, thereby improving the overall structural strength of the backpack support assembly and transmitting force. This improves the phenomenon that the support plate can only distribute the weight locally, which helps to improve the backpack support effect of the backpack support assembly to a greater extent and improve the user's comfort when carrying the backpack for a long time during hiking or carrying heavy loads.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please refer to Figures 1 to 9 The back support assembly includes a support plate 1 and at least one rigid support strip 2. The rigid support strip 2 has an arc-shaped segment 21. The front wall surface of the rigid support strip 2 is attached to the support plate 1. The support plate 1 forms an arc-shaped contact area 11 corresponding to the arc-shaped segment 21.

[0019] As can be seen from the above description, the beneficial effects of this utility model are as follows: This backpack support assembly has a connected support plate 1 and a rigid support strip 2. The support plate 1 can make large-area contact with the user's back, thereby effectively distributing the weight of the backpack and avoiding discomfort to the user's back due to excessive local pressure. The rigid support strip 2 can support the support plate 1, thereby improving the overall structural strength of the backpack support assembly and transmitting force, improving the phenomenon that the support plate 1 can only distribute the weight locally, which is conducive to improving the backpack support effect of the backpack support assembly to a greater extent and improving the comfort of the user when carrying the backpack for a long time during hiking or carrying heavy loads.

[0020] Furthermore, the support plate 1 is a deformable thin plate.

[0021] As described above, the support plate 1 is shaped by the rigid support strip 2, which facilitates the processing and manufacturing of the support plate 1. The rigid support strip 2 can adapt to the spinal curve of the human body through ergonomic design, thereby improving the comfort of wearing the back support component.

[0022] Furthermore, the support plate 1 is provided with an installation cavity, and the rigid support strip 2 is installed in the installation cavity.

[0023] As described above, the mounting cavity is used to accommodate the rigid support strip 2. The rigid support strip 2 located in the mounting cavity can cause the mounting cavity to deform, thereby achieving the shaping of the entire support plate 1.

[0024] Furthermore, it also includes a webbing 3, which is connected to the support plate 1, and the webbing 3 and the support plate 1 enclose the mounting cavity.

[0025] As can be seen from the above description, the molding method of the mounting cavity is simple and facilitates the processing and manufacturing of the back support components.

[0026] Furthermore, the mounting cavity has an opening 4 for taking out and placing the rigid support strip 2.

[0027] As described above, the rigid support bar 2 and the support plate 1 are detachably connected. Users can choose to install the rigid support bar 2, which is highly compatible with their own spinal curve, in the installation cavity. This allows the back support component to better adapt to their actual situation, which is conducive to improving the back support effect and wearing comfort of the back support component to a greater extent. At the same time, it also allows the support plate 1 to use the same set of production molds to obtain support plates 1 of uniform specifications during production. Subsequently, the rigid support bar 2 is used for shaping, which helps to save the mold opening cost of the back support component that is adapted to the user's spinal curve.

[0028] Furthermore, the webbing 3 includes a fixed part 31 and a blocking part 32 connected together. The fixed part 31 is fixedly connected to the support plate 1, and the blocking part 32 is used to block the take-up and put-out port 4.

[0029] As described above, the shielding part 32 can block the access port 4, thereby making the back support assembly look more concise and reducing the risk of the user being scratched by the rigid support strip 2.

[0030] Furthermore, when the blocking part 32 blocks the take-up and put-out port 4, one end of the blocking part 32 away from the fixing part 31 passes around the edge of the support plate 1 and is placed on the side of the support plate 1 away from the rigid support strip 2.

[0031] As described above, during use, the end of the shielding part 32 away from the fixing part 31 is clamped between the user's back and the support plate 1, thereby closing the take-up and take-down port 4 and preventing the rigid support bar 2 from accidentally protruding from the take-up and take-down port 4, which would cause the support plate 1 to deform unexpectedly.

[0032] Furthermore, the shielding part 32 is provided with a first Velcro strap, and the support plate 1 is provided with a second Velcro strap that cooperates with the first Velcro strap.

[0033] As can be seen from the above description, after the first Velcro and the second Velcro are engaged, the blocking part 32 achieves the sealing of the take-up opening 4, thereby more effectively preventing the rigid support strip 2 from accidentally protruding from the take-up opening 4, so as to prevent the support plate 1 from undergoing unexpected deformation.

[0034] The backpack includes a main body, on which the aforementioned back support components are mounted.

[0035] As can be seen from the above description, backpacks with the aforementioned back support components can provide users with a more comfortable carrying experience.

[0036] Furthermore, the back support assembly is detachably connected to the back panel of the main body.

[0037] As described above, users can choose whether to install a back support component according to their actual needs, which helps to improve the flexibility of backpack use.

The support plate 1 forms an arc-shaped contact area 11 corresponding to the arc-shaped segment 21. The arc-shaped contact area 11 corresponds to the upper part of the user's back. The rigid support strip 2 can be a high-strength strip such as an aluminum alloy strip or a stainless steel strip.

[0039] Considering factors such as the production of consumable materials and the weight of the back support components, the support plate 1 is a deformable thin plate. The support plate 1 is shaped by the rigid support strip 2 to conform to the user's spinal curve. Considering factors such as material toughness and cost, the support plate 1 is made of at least one of PP (polypropylene), PVC (polyvinyl chloride), EVA (ethylene-vinyl acetate copolymer), TPU (thermoplastic polyurethane elastomer), PTE (polyethylene terephthalate), ABS (acrylonitrile-butadiene-styrene copolymer), PA (polyamide), PC (polycarbonate), and PBT (polybutylene terephthalate).

[0040] The support plate 1 has a mounting cavity, and the rigid support strip 2 is installed in the mounting cavity. In some embodiments, the mounting cavity may be formed inside the support plate 1, and the mounting cavity is formed using a core component in the injection mold during the injection molding process of the support plate 1.

[0041] In one or more embodiments, the rigid support strip 2 is detachably connected to the support plate 1, specifically, as shown in... Figure 4 and Figure 6 As shown, the mounting cavity has an opening 4 for taking out and putting in the rigid support strip 2. In this embodiment, the upper part of the webbing 3 is not fixedly connected to the support plate 1. Therefore, the upper part of the webbing 3 and the support plate 1 form the opening 4.

[0042] Please combine Figure 1 , Figure 3 , Figure 4 and Figure 6 In some embodiments, the webbing 3 includes a fixed part 31 and a blocking part 32 connected together. The fixed part 31 is fixedly connected to the support plate 1. The connection between the fixed part 31 and the blocking part 32 and the support plate 1 forms the take-up and put-out opening 4. The blocking part 32 is used to block the take-up and put-out opening 4.

[0043] like Figure 7 As shown, when the blocking part 32 blocks the take-up and put-out port 4, the end of the blocking part 32 away from the fixing part 31 goes around the edge of the support plate 1 and is placed on the side of the support plate 1 away from the rigid support strip 2.
