Description

Technical Field

[0001] The present invention relates to a carrying device, in particular to an autonomously adjustable intelligent load-reducing carrying device, belonging to the technical field of intelligent wearable devices. Background Art

[0002] Experimental studies have shown that the reason why backpacks feel heavy when you are exercising is that the up and down shaking of the backpack during exercise creates impact on the human body. The impact of this shaking can be up to three times the weight of the backpack, so when walking or running with a backpack, you will be under greater pressure and have a greater risk of fatigue or injury.

[0003] It is understood that in modern warfare, the weight carried by individual soldiers is constantly increasing, usually reaching dozens of kilograms. The huge weight will not only seriously affect the combat effectiveness of individual soldiers, but the long-term impact will greatly increase the burden during exercise, accelerate physical energy consumption, and increase the risk of injury.

[0004] A search shows that the Chinese patent document with application number 202010008902.5 discloses a self-restoring carrying device, including a buffer device, a back clip, a hard elastic shoulder strap and a waist support device. The back clip is connected to the waist support device and one end of the hard elastic shoulder strap respectively, and the other end of the hard elastic shoulder strap is connected to the buffer device; the back clip, the hard elastic shoulder strap and the buffer device form an elastic arch support structure. Although this technical solution can reduce the pressure of the back load on the wearer's upper body, the buffer devices are actually vertical springs, which are not only complex in structure, but also the rebound of the elastic buffer after energy storage will aggravate the vertical vibration of the load, which is not conducive to suppressing vertical impact; in addition, its force collection point is at the waist, which is easy to increase the risk of waist injury. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent load-reducing carrying device that can effectively eliminate vertical amplitude, suppress load impact force, and significantly reduce fatigue and injury risks in response to the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned purpose, the basic technical scheme of the intelligent load-reducing carrying device of the present invention is as follows: it comprises a back plate with shoulder straps on both sides of one side, and vertical slide rails are fixed on both sides of the other side of the back plate and are respectively equipped with constant force damping devices; the slide rails form a moving pair with the load slide plate through a roller assembly, and the constant force damping device contains a fixed plate with a circular arc groove and a swinging member with one end hinged on the fixed plate and the other end slidingly matched with the circular arc groove; the middle part of the swinging member is hinged to the protruding end of the push rod through a short connecting rod, and the inserted end of the push rod forms a horizontal moving pair with the sleeve fixed to the back plate and tends to retract into the sleeve elastically; the swinging member is connected to the upper end of the connecting rope at the point where it cooperates with the circular arc groove, and the lower end of the connecting rope is connected to the load slide plate.

[0007] The present invention not only puts the load sliding plate in an elastic floating state through the constant force damping device, but also, by virtue of the horizontal elastic movable sub-buffer in the constant force damping device, does not increase the vibration displacement due to buffer rebound, thereby effectively suppressing the impact pressure of the load during walking and significantly reducing the risk of fatigue and injury.

[0008] A further improvement of the present invention is that the back plate is equipped with a wireless communication module, and the shoulder strap is equipped with a pressure sensor whose signal output end is connected to the wireless communication module. Therefore, the pressure during exercise can be measured in real time, and the data can be transmitted to the mobile terminal through the wireless communication module to realize real-time monitoring of the stress status of the human body.

[0009] A further improvement of the present invention is that the backboard is also equipped with a linear permanent magnet generator and a rechargeable battery, so that the mechanical energy during walking can be converted into electrical energy, which is stored in the rechargeable battery to power the wireless communication module.

[0010] A further improvement of the present invention is that the fixing plate is rectangular, and the arc groove takes the hinge hole at the inner lower corner of the fixing plate as the center and extends from the middle upper part to the outer lower part of the fixing plate.

[0011] A further improvement of the present invention is that the insertion end of the push rod forms a horizontal moving pair with a sleeve fixed on the back plate through an end cap, the end cap is axially limited by a reducing ring adjacent to the end of the sleeve, and the push rod is sleeved with a spring located between the inner side of the reducing ring and the end face.

[0012] The present invention is further improved in that the swinging member is a pair of two pieces, one end of which is hinged to the hinge hole of the fixed plate, the other end clamps the fixed rope head, and the middle hole clamps one end of the hinged short connecting rod.

[0022] The intelligent load-reducing carrying device of this embodiment is self-adjustable. Figure 1 and Figure 2 As shown, the upper part of both sides of one side of the rectangular back plate 2 is provided with strap holes 6 spaced apart from each other, and the strap 4 can be installed according to the pressure and different body shapes. The strap 4 is equipped with a pressure sensor 20. The other side of the back plate 2 is fixed with a T-shaped vertical slide rail 17 with the rail surface extending outward, and a constant force damping device 7 is installed in the middle and upper part (see Figure 3 ). The materials of the back plate and the load slide plate are both high-strength and light-weight engineering plastics. A pair of rollers of the roller assembly 19 are respectively installed on both sides of the rail surface of the slide rail 17. The roller assembly 19 is installed on both sides of the load slide plate 1, so that it can "float" vertically relative to the back plate 2 through the vertical moving pair, that is, when the human body is moving, the load slide plate bearing the external load can slide downward relative to the back plate.

[0023] In addition, the back plate 2 is equipped with a wireless communication module 9, a linear permanent magnet generator 10 and a rechargeable battery 8. The signal output end of the pressure sensor 20 on the shoulder strap 4 is connected to the wireless communication module 9, which can measure the pressure data in motion in real time and send it to the mobile terminal for communication, so as to monitor the stress condition of the human body. The moving part of the linear permanent magnet generator 10 that cuts the magnetic lines of force is connected to the load slide 1, which is used to convert the mechanical energy during walking into electrical energy and store it in the rechargeable battery 8 to power the wireless communication module 9. In addition, the linear permanent magnet generator 10 will also produce a certain damping during the power generation process, which helps to enhance the load reduction effect.

[0024] Load slide 1 Figure 4 As shown, there are multiple Japanese-shaped buckles 3 to adapt to different forms of external loads, which is convenient for external loads to be directly selected and mounted through the buckles, and rope end holes 5 are provided on both sides of the lower part for fixing the ends of the connecting ropes.

[0025] Constant force damping device 7 Figure 5 and Figure 6As shown, the rectangular fixed plate 12 has an arc groove 16 extending from the middle upper part to the outer lower part with the hinge hole A3 at the inner lower corner as the center of the circle. One end of the two pairs of swinging members 15 are hinged together in the hinge hole A3 of the fixed plate 12, and the other end A1 clamps the fixed rope head member 14' to form a sliding fit with the arc groove 16, which can limit the swing range of the swinging member and the compression and elongation of the spring. The middle hole A2 of the two swinging members 15 is connected to the extended end of the push rod 18 through the clamped hinged short connecting rod 14, and the inserted end of the push rod 18 forms a horizontal moving pair with the sleeve 13 fixed on the back plate 2 through the end cap 18-1, and the end cap 18-1 is axially limited by the reduction ring 13-1 located near the end of the sleeve 13, and the push rod 18 is sleeved with the spring 17' located between the inner side of the reduction ring 13-1 and the end face 18-1, so it tends to retract into the sleeve 13. The position where the swinging member 15 cooperates with the arc groove is connected to the upper end of the connecting rope 11 through the rope head member 14 ′, and the lower end of the connecting rope 11 is connected to the rope head hole 5 of the load slide plate.

[0026] When in use, the load slide plate can be connected to the arc groove of the constant force damping device and the restraint buffering effect of the horizontal spring through the connecting rope (see Figure 7 , Figure 8 ), slides up and down relative to the backboard, thereby effectively suppressing the follow-up displacement of the external load when a person is walking or running, significantly reducing the vertical impact force, and greatly alleviating the pressure on the human body.

[0027] Experiments have shown that the intelligent load-reducing carrying device of this embodiment significantly reduces the pressure from external loads during exercise, reduces exercise intensity and the risk of injury, and can also generate electricity and store energy by itself, which helps to achieve intelligent, miniaturized and individualized equipment.

[0028] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
