TECHNICAL FIELD
[0001] The utility model relates to a backpack, in particular to a backboard structure of a mountaineering backpack. BACKGROUND
[0002] Mountaineering backpack, namely the backpack of mountaineers, is a backpack used to load supplies and equipment in the mountaineering process. It is not only an important equipment in mountaineering, but also an indispensable item in various travels. The mountaineering backpack can load and carry various supplies required for mountaineering, such as food, water, clothes, first-aid supplies, etc., to meet the survival needs of mountaineers in the outdoors.
[0003] The mountaineering backpack needs to have certain strength, and the mountaineering backpack needs to have sufficient rigidity while ensuring comfort, so that the items in the backpack can be effectively supported. At present, the support structure of the backboard of the mountaineering backpack mostly uses single-hardness carbon fiber material or traditional composite material, and the main structure usually includes a carbon fiber layer and a sponge layer. The carbon fiber layer provides support force through plain and twill weaving methods, and the sponge layer is used to increase comfort. In the prior art, the design of the carbon fiber support plate mostly adopts the structure of two carbon fiber layers (plain and twill) combined with a sponge layer to achieve the balance of light weight and support, but the current mountaineering backpack still has the following problems:
[0004] 1. The carbon fiber support plate usually adopts homogeneous weaving density, which cannot be optimized according to the mechanical requirements of different human body parts. For example, the scapula and lumbar spine area needs higher support force, while other areas need more flexibility to reduce weight and improve comfort. The prior art fails to achieve such zoned optimization, resulting in insufficient support rigidity or poor comfort.
[0005] 2. The carbon fiber support plate usually does not have a single-sided rigidity design, which cannot effectively limit the bending of the backboard in the direction of stretching to the torso. This design defect is particularly evident in heavy backpacking or outdoor trail scenes, which may cause excessive stretching of the spine and increase the risk of spinal injury. Lack of dynamic rigidity adjustment function, the existing technology cannot automatically adjust the rigidity of the backboard according to the weight of the backpack or the motion state of the user. For example, when the weight of the backpack increases, the prior art cannot provide stronger support, and when the user needs flexibility, it also cannot reduce the rigidity to adapt to the motion requirements.
[0006] 3. The surface hardness of the carbon fiber support plate is low, and the wear resistance is poor, which is easy to produce scratches or wear in long-term use, affecting the service life of the backboard. In addition, the brittleness of carbon fiber material is large, which is easy to break in brittle state when impacted or overloaded, and difficult to repair.
[0007] 4. The function is relatively single, and lacks intelligent and humanized design. SUMMARY

[0033] As shown in Figures 1-4 A back panel structure of a mountaineering bag, comprising an inner support layer 2, a stiffness adjustment layer 3 and an outer stretch layer 4 connected in turn from inside to outside, the inner support layer 2 has at least two areas with different densities, the stiffness adjustment layer 3 comprises a carbon fiber base material 31 and at least two rows of chopped carbon fiber plies 32, one row of chopped carbon fiber plies contains a plurality of individual chopped carbon fiber plies, the chopped carbon fiber plies 32 protrude from the surface of the carbon fiber base material, the at least two rows of chopped carbon fiber plies 32 are arranged horizontally and transversely on the surface of the carbon fiber base material 31 from top to bottom, and the chopped carbon fiber plies are connected with the outer stretch layer, a spacing groove 33 is formed between the two adjacent rows of chopped carbon fiber plies, and the inner side of the inner support layer 2 is provided with an intelligent monitoring assembly 6. The inner support layer 2 has areas with different densities, as shown inFigure 3 The first density region 21 and the second density region 22 are formed in the stiffness adjustment layer 3, thereby forming different stiffness regions.
[0034] With particular reference to Figure 5 As shown in the figure, in the stiffness adjustment layer 3, a plurality of chopped carbon fiber layers are closely arranged in a row, and the number of individual chopped carbon fiber layers is determined according to the overall size.
[0035] The inner support layer 2 comprises at least one plain weave carbon fiber cloth 23 and at least one twill weave carbon fiber cloth 24 connected in a close fit, and the at least one plain weave carbon fiber cloth 23 and the at least one twill weave carbon fiber cloth 24 are connected in an alternating and spaced manner. In this embodiment, two plain weave carbon fiber cloths and two twill weave carbon fiber cloths are provided, and the carbon fiber cloths with different weave structures are arranged in an alternating and spaced manner to provide sufficient support force from various directions. At the same time, a certain elasticity is generated, and discomfort is not caused due to excessive rigidity.
[0036] In addition, the plain weave carbon fiber cloth 23 and the twill weave carbon fiber cloth 24 are both provided with different density regions, and are formed into inhomogeneous woven cloths. The weaving density and direction of each region are optimized according to ergonomics. The weaving density in the scapula and lumbar region is 1.5 times that of other parts to provide stronger support, and the density of other regions can be appropriately reduced to increase flexibility and reduce weight to a certain extent.
[0037] The width of the spacing groove 33 is less than or equal to the thickness of the chopped carbon fiber layer 32, and the chopped carbon fiber layer 32 forms an outwardly protruding structure, so that the backboard has single-sided rigidity. The backboard can only be bent in the direction of the curved torso of the human body, and cannot be bent in the direction of the stretched torso. When bent in the direction of the stretched torso, the mutual approach of adjacent chopped carbon fiber layers will collide, thereby inhibiting the activity in this direction. This function plays an important role in protecting the spine. Because the backpack is usually used in outdoor cross-country, heavy-load hiking, etc., the weight of the backpack is usually large in such scenarios, and the heavy backpack pulls the spine from the back, and there is always a risk of the spine stretching even collapsing backward. The backboard of the backpack realizes the single-sided rigidity, which solves this problem from the instrument, and greatly reduces the risk of damage to the spine.
[0038] In addition, the stiffness adjustment layer 3 is provided with a shape memory alloy part 34, which is an alloy material that can completely eliminate the deformation that occurs at a lower temperature and restore the original shape before deformation after heating. The stiffness adjustment layer can dynamically adjust the stiffness according to the motion state of the user or the weight of the backpack. For example, when the weight of the backpack increases, the stiffness adjustment layer can automatically increase the rigidity to provide better support; when the user needs more flexibility, the stiffness can be reduced.
[0039] The outer stretching layer 4 comprises a first woven plate 41, a second woven plate 42 and a third woven plate 43 connected in sequence, wherein the first woven plate is woven by TPU pre-impregnated carbon fiber, the second woven plate is woven by TPU pre-impregnated glass fiber, and the third woven plate is woven by TPU pre-impregnated M-shaped carbon fiber, and the first woven plate is connected with the stiffness adjusting layer. Different materials are used to form a multi-layer structure, and the rigidity and modulus of each layer structure are different. The presence of the woven plate provides rigidity to the outer layer. TPU pre-impregnated material is used because it has high tensile ductility. Glass fiber is used because it has higher modulus than carbon fiber and has high toughness, which will produce larger deformation under stress without breaking. M-shaped carbon fiber is used because it has high modulus that other carbon fibers do not have. It can produce larger deformation under stress without breaking the internal structure. The combination of the three forms an outer stretching layer that has both rigidity and toughness, characterized by high tensile rate and low compression rate, further enhancing the overall double-hardness characteristics of the backboard and greatly protecting the spine health.
[0040] A scratch-resistant and wear-resistant coating 5 is coated on the surface of the carbon fiber woven plate 43, which can be formed of silica gel material or glass resin, etc., to improve durability.
[0041] The inner side of the inner support layer 2 is provided with a sponge layer 1, and the intelligent monitoring assembly 6 comprises a temperature sensor 7 and a humidity sensor 8. The temperature sensor and the humidity sensor are arranged between the sponge layer and the inner support layer. The outer stretching layer is provided with a controller 9 and a battery. The temperature sensor and the humidity sensor are connected with the controller, and the controller is connected with the battery. The sponge layer is relatively soft, which improves comfort. The controller and the battery can be arranged on the side of the outer support layer. The placement positions are selected as the lower corners of the scapula on both sides, the midpoint of the thoracic vertebrae, and 5 cm on both sides of the lumbar vertebrae. The temperature and humidity data of these five points can roughly reflect the heat conversion of the human body. The data is converted into digital signals through chemical signals and electrical signals by the controller. The controller transmits the data to the mobile terminal through Bluetooth. The controller selects an existing central signal processor, which has communication performance and can communicate with the remote mobile phone.
[0042] The intelligent monitoring assembly comprises a GPS chip and a speed sensor, which are connected with the battery respectively. The GPS chip positioning can be selected to be turned on or off. The positioning is expressed in latitude and longitude and can be transmitted to the mobile terminal in real time. Or it can provide position information to the hiker when the mobile phone loses signal in the wild, playing a pilot role. Or if the hiker's backpack is lost, it can be located and found back through the mobile phone. The speed sensor can calculate the climbing altitude of the whole journey, and through various sports information such as distance, average speed, and maximum speed, these information can be uploaded to the mobile terminal through the controller.
[0043] In addition, when hiking in the wild, dangerous situations may be encountered, and contact with the outside world may be lost. When this happens, the hiker should call for help in time. A one-key alarm device can be provided. When the hiker is in danger and cannot contact the outside world, the one-key alarm can be selected to send the current GPS coordinates to the other party, so that the hiker can be rescued.
[0044] A fall detection function can also be added. When the system detects that the user has suddenly fallen or has been stationary for a long time, an automatic distress signal is triggered, and the GPS coordinates are sent to the preset emergency contact person, ensuring that the user can still be rescued when he or she cannot manually call for help.
[0045] Energy harvesting: Piezoelectric materials or solar cells can be added to the intelligent monitoring component to use the user's movement or sunlight to power the sensor and GPS chip, reducing dependence on batteries and extending the use time of the device.
[0046] It should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements for some technical features, but any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
