Description

Technical Field

[0001] The present application relates to a carrying device, and in particular to a multi-mode suspension carrying system with a power generation device and a backpack with the suspension carrying system. Background Art

[0002] Carrying a backpack is a common way of transporting loads. It is often used in outdoor activities such as wilderness survival, military and police duty, emergency rescue, and mountaineering. When the backpack is stationary, the force exerted on the body by the backpack is equal to the weight of the backpack. However, when walking or running with the backpack on your back, the backpack will vibrate up and down as the center of gravity of the human body moves. The peak force exerted on the body during the vibration process increases significantly compared to when it is stationary, which increases the weight of the human body and is not conducive to outdoor weight-bearing walking. The suspended carrying system includes a strap carrier, a load carrier, and a suspension connection module connecting the strap carrier and the load carrier. The strap carrier is connected to the strap, and the load carrier is connected to the backpack. Under the action of the suspension connection module, the backpack can vibrate up and down along the strap carrier along with the load carrier, which can effectively buffer the pressure of the weight on the human body during walking.

[0003] For example, a Chinese invention patent application document with publication number CN 110720737A discloses an adjustable suspended decompression carrying mechanism, including a carrying plate, a mounting plate, a vibration-damping suspension mechanism and a vibration-damping adjustment mechanism. The carrying plate is slidably connected to the mounting plate, the carrying plate is connected to the mounting plate through the vibration-damping suspension mechanism, the vibration-damping adjustment mechanism is fixed to the carrying plate, the vibration-damping adjustment mechanism is connected to the vibration-damping suspension mechanism, the mounting plate is used to carry a backpack or a load, and the carrying plate is connected to a shoulder strap; the vibration-damping suspension mechanism includes an elastic belt and multiple roller mechanisms, the multiple roller mechanisms are respectively arranged at the upper and lower ends of the carrying plate and / or the mounting plate, and are arranged between the carrying plate and the mounting plate, one end of the elastic belt is connected to the mounting plate, and the other end of the elastic belt is connected to the vibration-damping adjustment mechanism by successively bypassing multiple roller mechanisms, and the vibration-damping adjustment mechanism is fixed to the carrying plate.

[0004] However, most of the existing suspension carrying systems have a single mode. On the other hand, in outdoor activities, portable electronic products are often needed to be carried, and electronic products usually need to be recharged. There are backpacks with power generation functions in the existing technology, but there are problems such as low power generation efficiency or complex structure that increases the weight of the carrying system. Summary of the invention

[0005] The present application provides a multi-mode suspension backpack system with a power generation device, which has a good suspension decompression effect, a power generation device with a sophisticated structure and high power generation efficiency, and a multi-mode backpack system.

[0089] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0090] In order to better describe and illustrate the embodiments of the present application, reference may be made to one or more drawings, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of the invention of the present application, any of the currently described embodiments or preferred methods.

[0091] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0092] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0093] like Figure 1 to Figure 5 As shown, a multi-mode suspension backpack system with a power generation device includes a backpack carrier 10, a load carrier 20, a suspension connection module 30, a power generation module 40, a mode selection module 50 and a balance adjustment module 60. The load carrier 20 is slidably matched with the backpack carrier 10, the backpack carrier is used to carry the backpack, and the load carrier is used to carry the load.

[0094] The suspension connection module 30 is used to make the load carrier and the backpack vibrate up and down when a person walks or runs, so as to reduce the pressure of the load on the shoulders of the human body. The suspension connection module 30 includes an elastic rope 32 and a plurality of fixed pulleys 31. The plurality of fixed pulleys 31 are arranged between the load carrier 20 and the shoulder strap carrier 10. The fixed pulleys 31 are respectively installed on the shoulder strap carrier 10 or the load carrier 20, and at least one of the fixed pulleys is installed on the shoulder strap carrier. The plurality of fixed pulleys are respectively arranged at both ends along the sliding direction of the shoulder strap carrier and the load carrier. When the carrying system is in use, the load carrier slides up and down along the shoulder strap carrier. Therefore, it can also be understood that multiple fixed pulleys are respectively installed on the upper and lower ends of the shoulder strap carrier or the load carrier, and the fixed pulley at the upper end is arranged alternately with the fixed pulley at the lower end. One end of the elastic rope 32 is a fixed end, which is installed on the shoulder strap carrier 10, and the other end of the elastic rope 32 is a suspended end. The suspended end passes around multiple fixed pulleys 31 in turn and is connected to the balance adjustment module 60. The balance adjustment module 60 is used to adjust the elastic force of the elastic rope.

[0095] Decompression principle of suspended connection module:

[0096] When a person is walking or running, the displacement curve of the center of gravity can be approximated to a sine curve. When the weight moves downward, the human body does work on the weight, and at the same time, the weight will produce a great impact load on the shoulders of the human body. The suspended carrying system can make the amplitude of the load connected to the load carrier always smaller than the amplitude of the center of gravity of the human body, which is equivalent to reducing the up and down movement of the load relative to the ground, which is similar to the load being suspended on the ground and moving with the human body, so as to reduce the mechanical work done by the human body on the load, and also alleviate the impact load of the carrying strap on the shoulders of the human body when walking. The design of elastic rope and pulley group can extend the length of the elastic body, enhance the suspension effect, improve the decompression function of the carrying system, and further improve the stability of the human body when walking with weight.

[0097] The power generation module 40 is used to convert the mechanical energy of the up and down movement of the load carrier into electrical energy, and can charge portable electronic products. The power generation module 40 includes a power generation clutch, a gear set 43 and a generator 44 installed on the shoulder strap carrier 10. The power generation clutch is coupled with one of the fixed pulleys installed on the shoulder strap carrier. When the power generation clutch is closed and connected with the fixed pulley, mechanical energy is transmitted and the generator generates electricity. When the power generation clutch is disconnected from the fixed pulley, the transmission is terminated and the generator stops generating electricity. The gear set 43 connects the power generation clutch and the generator and is used to multiply the rotation speed of the fixed pulley.

[0098] Working process of power generation module:

[0099] The power generation module converts the mechanical energy of the load's up and down movement into electrical energy through the power generation clutch, gear set and generator to charge related mobile electronic devices. When the transmission component of the power generation clutch is closed and connected with the fixed pulley, the transmission is carried out to enable the generator to generate electricity, and when it is separated from the fixed pulley, the transmission is disconnected and the generator stops generating electricity.

[0100] A power generation clutch is provided, which can be clutched and connected with the fixed pulley of the suspension connection module. The power generation mode can be selected according to the user's needs, that is, power generation or no generation. When charging is not needed, the generator is disconnected to protect the components of the power generation module and extend the service life of each component. A gear set is provided to multiply the rotation speed of the fixed pulley to improve the power generation efficiency.

[0101] The power generation module of the present application is coupled to the suspension connection module of the elastic rope fixed pulley combination. The number of rotations of the fixed pulley can increase with the increase of the movement amplitude, and the power generation efficiency is better. At the same time, the power generation module of the present application has a sophisticated structure, light weight and good integrity.

[0102] The mode selection module 50 includes a telescopic shaft 52 and a limiting hole 55, and the limiting hole and the telescopic shaft are respectively arranged on the shoulder strap carrier and the load carrier, that is, the limiting hole is arranged on the load carrier and the telescopic shaft is arranged on the shoulder strap carrier, or the limiting hole is arranged on the shoulder strap carrier and the telescopic shaft is arranged on the load carrier, and the telescopic shaft has a first state of being inserted into the limiting hole and a second state of being detached from the limiting hole and can be switched between the first state and the second state.

[0103] The carrying system can realize suspension or non-suspension mode selection under the action of the mode selection module 50. The telescopic shaft 52 moves axially into the limiting hole 55 to lock the load carrier 20 and the shoulder strap carrier 10, and the carrying system enters the non-suspension mode. The telescopic shaft 52 moves in the opposite direction to disengage from the limiting hole 55, releasing the lock between the load carrier 20 and the shoulder strap carrier 10, and the carrying system enters the suspension mode.

[0104] The mode selection module 50 and the power generation module 40 can cooperate with each other. In this cooperative cooperation mode, when the backpack system is in the suspension mode under the action of the mode selection module, the power generation module 40 is adjusted so that the power generation clutch and the fixed pulley 31 are in a closed connection, and the power generation module 40 is started to convert the mechanical energy of the rotation of the fixed pulley into electrical energy; when the backpack system is in the fixed mode under the action of the mode selection module, the power generation module 40 is adjusted so that the power generation clutch and the fixed pulley 31 are disconnected, and the generator stops generating electricity.

[0105] In another embodiment, in the suspension mode, the power generation module can be actively disconnected if power generation is not needed; in the non-suspension mode, the fixed pulley does not rotate, there is no mechanical energy transmission, and the power module can be continuously developed.

[0106] As an implementation method of the power generation clutch, Figure 6 to Figure 11As shown, the power generation clutch includes: a first knob 41, a support column 48, a transmission gear 42, a connecting shaft 45 and a first spring 46. The transmission gear 42 is coaxial with one of the fixed pulleys 31 installed on the shoulder carrier and can be connected in a clutch manner. The first knob 41 is located on the outside of the shoulder carrier and is coaxially arranged with the transmission gear 42. The transmission gear 42 and the fixed pulley 31 are both located on the inside of the shoulder carrier (i.e., between the shoulder carrier and the load carrier). The fixed pulley 31, the transmission gear 42, the shoulder carrier and the first knob 41 are arranged in sequence in a direction vertically penetrating the shoulder carrier.

[0107] The first knob 41 and the fixed pulley 31 can be connected in a clutched manner, and the first spring 46 is disposed between the fixed pulley 31 and the transmission gear 42; the support column 48 is located on the outer surface of the strap carrier 10, and cooperates with the first knob 41. The inner side surface of the first knob 41 is provided with a first inclined guide rail 41a that contacts and cooperates with the support column 48, and both ends of the inclined guide rail are provided with a first circumferential limiting groove 41b. The first inclined guide rail 41a is inclined along the circumference of the knob, and it can also be understood that the height between the guide rail surface and the plane where the inner edge of the knob is located is distributed from shallow to deep along the circumference of the knob, forming a drop in the axial direction of the knob.

[0108] The connecting shaft 45 passes through the first knob 41, the strap carrier 10, the transmission gear 42 and the fixed pulley 31 in sequence. Both ends of the connecting shaft 45 are provided with axial connecting members 45a. The first knob 41, the transmission gear 42 and the fixed pulley 31 are all rotatably matched with the connecting shaft 45, that is, the first knob 41, the transmission gear 42 and the fixed pulley 31 can all rotate around the connecting shaft, and the connecting shaft can move axially. The axial stoppers at both ends of the connecting shaft have at least the following two functions: first, to limit the two ends of the connecting shaft 45 from slipping out of the first knob 41 or the fixed pulley 31 when the connecting shaft moves axially; second, to serve as a force-bearing component when the connecting shaft moves axially.

[0109] When the first knob is turned, the inclined guide rail inside the first knob, the support column on the support seat and the first spring cooperate with each other, and the connecting shaft 45 can move axially to adjust the clutch state of the fixed pulley and the transmission gear: turn the first knob 41 in the positive direction (usually clockwise), and the inclined guide rail inside the first knob abuts against the support column from deep to shallow (it can also be understood that the height of the guide rail surface from the plane where the inner edge of the first knob is located is from high to low). Since the support column is fixed, the first knob 41 moves outward, pulling the connecting shaft 45 to move toward the side of the first knob 41, and the connecting shaft 45 drives the fixed pulley 31 to move axially, and the fixed pulley 31 is locked with the transmission gear 43, and at the same time compresses the first spring 46, thereby achieving The fixed pulley 31 is now in a closed connection with the transmission gear 43. At this time, the connecting shaft 45 is axially locked, that is, there is no axial movement space. The power of the fixed pulley 31 is transmitted through the transmission gear 42 and the gear set 43, and the generator 44 generates electricity. The first knob 41 is rotated in the opposite direction (usually counterclockwise), and the inclined guide rail in the first knob abuts against the support column from shallow to deep (it can also be understood that the height of the guide rail surface from the plane where the inner edge of the knob is located is from low to high). Since the support column is fixed, the connecting shaft 45 is axially released, and the first spring is reset, pushing the fixed pulley 31, so that the fixed pulley 31 is disconnected from the transmission gear 42, and at the same time pulling the first knob 41 to move inward, and the generator 44 stops generating electricity.

[0110] During the rotation of the first knob, the stroke of the first spring is at least consistent with the stroke difference formed by the slope of the first inclined plane guide rail, or slightly larger than the stroke difference formed by the slope of the inclined plane.

[0111] The first circumferential limit groove 41b in the first knob 41 is used to cooperate with the support column after the knob is rotated into place to limit the circumferential rotation of the first knob in the absence of external force. After the knob is rotated into place, the support column slides into the corresponding limit groove to limit the knob circumferentially. In the absence of external force, the knob will not rotate spontaneously.

[0112] The transmission gear 42 and the fixed pulley 31 can be connected in a clutch manner. For a specific connection method, see Fig. 9 The end of the fixed pulley 31 connected to the transmission gear 42 has a connecting portion 31a coaxial with the fixed pulley, and the side of the transmission gear 42 connected to the fixed pulley 31 has an adapting groove 42a coaxial with the transmission gear 42, and the connecting portion 31a is adapted to the adapting groove 42a, which is used for the detachable connection between the fixed pulley and the transmission gear. An installation cavity 31b is provided inside the connecting portion 31a and close to the end of the transmission gear, and the installation cavity 31b is connected with the adapting groove 42a. The first spring 46 is placed in the installation cavity 31b, and one end of the first spring abuts against the bottom of the installation cavity 31b, and the other end of the first spring abuts against the bottom of the adapting groove 42a.

[0113] The first spring is used as a force-applying component to disconnect the fixed pulley from the transmission gear. When the fixed pulley is locked and connected to the transmission gear, the first spring is in a compressed state. When the first knob moves inward to release the connecting shaft, the elastic force of the first spring is released, pushing the fixed pulley to disengage from the transmission gear. As a specific implementation of the first spring, the first spring 46 can be a disc spring, which is sleeved on the connecting shaft 45.

[0114] When the first knob is rotated and the connecting shaft is pulled to move outward, the fixed pulley and the transmission gear can be locked under the pulling force of the first knob and the connecting shaft, and the fixed pulley and the transmission gear can achieve synchronous rotation in the locked state. In a more preferred embodiment, a circumferential limiter (not shown in the figure) is provided between the connecting portion of the fixed pulley and the adapting groove of the transmission gear. As a specific embodiment of the circumferential limiter, the circumferential limiter includes a positioning protrusion provided at the end of the connecting portion and a positioning groove provided at the bottom of the adapting groove, and the positioning protrusion and the positioning groove are adapted when the connecting portion and the adapting groove are closed and connected. It is used to further limit the relative movement of the fixed pulley and the transmission gear 42 when the fixed pulley and the transmission gear are closed and connected, and further strengthen the synchronous movement of the fixed pulley and the transmission gear 42. In other embodiments, the positions of the positioning protrusion and the positioning groove can also be exchanged.

[0115] Power generation mode: the first knob cooperates with the support column on the shoulder strap carrier to bear force, the first knob moves axially toward the shoulder strap carrier, pulls the connecting shaft outward, so that the connecting part of the fixed pulley is embedded in the adapter groove of the transmission gear, and at the same time compresses the first spring to lock the fixed pulley and the transmission gear (at this time, the first spring is in a compressed state), the load carrier moves up and down, and the elastic rope moves synchronously to retract and retract, driving the fixed pulley to rotate, the fixed pulley drives the transmission gear to rotate, the transmission gear drives the gear group to rotate, and the gear group drives the motor to move to generate electricity.

[0116] Non-power generation mode: Turn the first knob, and the first knob moves axially toward the load carrier under the action of the inclined guide rail inside the first knob. At the same time, the elastic force of the first spring is released (the stroke released by the rotation of the first knob is buffered by the first spring), pushing the fixed pulley so that the connecting part of the fixed pulley is disengaged from the adapter groove of the transmission gear, thereby disconnecting the transmission.

[0117] In order to facilitate the fitting installation between the clutch and the shoulder strap carrier, in a preferred embodiment, a gasket assembly 47 is provided between the transmission gear 42 and the shoulder strap carrier, and the gasket assembly is selected according to the specific installation space.

[0118] In order to enhance the adjustment stability of the clutch, in a preferred embodiment, a pair of support columns 48 are provided on the back load body 10, and the two support columns are arranged axially symmetrically with the axis of the connecting shaft; correspondingly, a pair of first inclined plane guide rails are provided in the first knob, and the two first inclined plane guide rails are arranged symmetrically with the axis of the first knob, and first circumferential limit grooves are provided at both ends of each first inclined plane guide rail (see Fig.10 ). Each support column cooperates with a corresponding first inclined guide rail.

[0119] The connecting shaft 45 connects the fixed pulley 31, the transmission gear 42, the strap carrier 10 and the knob 41. The connecting shaft can move axially under the action of external force. Both ends of the connecting shaft are provided with axial limit members 45a. As a specific implementation of the connecting shaft, Fig.11 As shown, the connecting shaft includes a first connecting member 45b and a second connecting member 45c arranged coaxially, the first connecting member and the second connecting member are coaxially connected and threadedly matched, and the other end away from the threaded connection is provided with a cap, which constitutes an axial limiter 45a. The connecting shaft of this embodiment is convenient for assembly and disassembly of various components.

[0120] The power generation clutch can be coupled with any fixed pulley installed on the shoulder carrier. In a more preferred embodiment, the power generation clutch can be connected to the fixed pulley near the suspension end of the elastic rope, and the fixed pulley is installed on the shoulder carrier 10. The fixed pulley closest to the end connected to the load carrier (i.e. the suspension end) has the largest movement range of the elastic rope, and the fixed pulley has a faster rotation speed, and the power generation module has a higher power generation efficiency.

[0121] The fixed pulley is distributed between the strap carrier and the load carrier and is installed on the strap carrier or the load carrier. In one embodiment, see Figure 5 , three fixed pulleys are provided and all are installed on the shoulder strap carrier 10. Along the path from the fixed end of the elastic rope 32 to the suspended end, the fixed pulleys are the first fixed pulley, the second fixed pulley and the third fixed pulley in sequence, wherein the first and third fixed pulleys are located near the top of the shoulder strap carrier, the second fixed pulley is located near the bottom of the shoulder strap carrier, the second fixed pulley is located between the first fixed pulley and the third fixed pulley, and the power generation clutch is coupled and installed with the third fixed pulley. The fixed end of the elastic rope is installed on the side of the second fixed pulley; an elastic rope fixing port 21 is provided near the bottom of the load carrier, and the suspended end of the elastic rope is fixedly connected to the elastic rope fixing port. This arrangement is conducive to maximizing the power generation power of the power generation module.

[0122] The gear set can be arranged in a conventional manner. In one embodiment, the gear set includes at least one output gear and one output gear, the input gear is meshed with the transmission gear, and the output gear is connected to the rotor shaft of the generator. The magnification of the gear set is 60 to 80 times.

[0123] To facilitate the generator's power output and connection with the device to be charged, the power generation module is also provided with a control board (not shown in the figure), which is preferably a PCB board. The control board is connected to the generator 44 and is used to rectify the alternating current output by the generator and convert it into direct current output.

[0124] See also Figure 6 In order to facilitate the installation of the gear set 43, the generator 44 and the control panel, the power generation module is also provided with a mounting plate 49, on which the gear set, the generator and the control panel can be mounted in a conventional manner. The generator and the gear set are respectively located on both sides of the mounting plate, and the control panel is arranged on the generator side and is electrically connected to the generator. The assembly method between the power generation module 40 and the strap carrier 10 is shown in FIG. Figure 2 , Figure 4 and Fig.12 The mounting plate 49 is fixedly connected to the shoulder carrier, the first knob of the power generation clutch and the transmission gear are respectively located on both sides of the shoulder carrier and are coaxially connected by a connecting shaft penetrating the shoulder carrier, and a packaging cover can be provided outside the generator. The power generation module of the present application is exquisitely designed and light in weight, which can reduce the burden on the back.

[0125] In most cases, the load needs to be decompressed under the action of the suspension connection module. In some specific cases, the load may also need to be fixed relative to the shoulder strap carrier. Therefore, the carrying system of the present application also includes a mode selection module 50. As a specific embodiment of the mode selection module, the mode selection module 50 includes a telescopic shaft 52 and a limiting hole 55. The limiting hole and the telescopic shaft are respectively arranged on the shoulder strap carrier and the load carrier. The telescopic shaft has a first state of being inserted into the limiting hole and a second state of being detached from the limiting hole and can be switched between the first state and the second state.

[0126] The limiting hole and the telescopic shaft are respectively arranged on the shoulder strap carrier and the load carrier, that is, the limiting hole is arranged on the load carrier and the telescopic shaft is arranged on the shoulder strap carrier, or the limiting hole is arranged on the shoulder strap carrier and the telescopic shaft is arranged on the load carrier. In one embodiment, the limiting hole 55 is located on the load carrier 20, and the axial direction of the limiting hole 55 is perpendicular to the sliding direction of the load carrier 20. The load carrier can slide up and down along the shoulder strap carrier, so it can also be understood that the limiting hole is arranged horizontally, and the telescopic shaft 52 is installed on the shoulder strap carrier. In one embodiment, the telescopic shaft 52 passes through the shoulder strap carrier 10 and is installed coaxially with the limiting hole 55. One end of the telescopic shaft 52 can be inserted into or out of the limiting hole 55, and the other end of the telescopic shaft 52 is the force-applying end.

[0127] The telescopic shaft moves axially under the action of external force to insert into or disengage from the limiting hole, thereby locking or unlocking the load carrier and the shoulder strap carrier. In order for the telescopic shaft to achieve axial movement, power needs to be applied to it. As an implementation method of applying force to the telescopic shaft, the mode selection module also includes a second knob 51 and a second spring 54. The second knob 51 is rotatably mounted on the shoulder strap carrier and is axially limited, that is, the knob can be rotated but does not undergo axial displacement. The inner side surface of the second knob 51 is provided with a second inclined surface guide rail 51a which is inclined along the circumference of the knob, and the second inclined surface guide rail is in abutment with the force application end of the telescopic shaft; a spring stopper 53 is arranged on the telescopic shaft and near the force application end, and the second spring 54 is sleeved on the telescopic shaft, and one end of the second spring is in abutment with the spring stopper 53 and the other end is in abutment with the shoulder strap carrier 20.

[0128] During the forward rotation of the knob 51, since the knob is axially stationary, the inclined guide rail on the inner side of the second knob cooperates with the telescopic shaft to apply force to the telescopic shaft, pressing the telescopic shaft 51 into the limiting hole 55, and at the same time compressing the second spring 54, the load carrier and the shoulder strap carrier are locked. In this mode, the load carrier and the shoulder strap carrier are in a relatively fixed mode; when the knob 51 is rotated reversely, the inclined guide rail 51a releases space toward the axial direction of the telescopic shaft, and the second spring 54 rebounds, causing the telescopic shaft 52 to disengage from the limiting hole 55, and the lock is released. In this mode, the load carrier and the shoulder strap carrier are in a suspended sliding mode.

[0129] The second inclined guide rail is distributed from shallow to deep on the inner side of the second knob along the circumference of the knob (i.e., the height of the guide rail surface from the plane where the inner edge of the second knob is located is from low to high) (see Fig.15 ), when the knob is turned clockwise or counterclockwise, the second inclined guide rail cooperates with the force-applying end of the telescopic shaft at different depths. As a specific implementation of the second inclined guide rail, when the second knob 51 is turned clockwise, since the knob is axially immobile, the second inclined guide rail 51a abuts against the telescopic shaft 52 from deep to shallow, forcing the telescopic shaft 52 to move axially toward the load carrier side and insert into the limiting hole 55. The telescopic shaft 52 is in the first state (such as Fig.13 and Fig.14 When the knob is turned counterclockwise, the second inclined guide rail 51a abuts against the telescopic shaft 52 from shallow to deep, and the second inclined guide rail 51a releases a certain space toward the axial direction of the telescopic shaft 52, and the second spring 54 rebounds, so that the telescopic shaft 52 is separated from the limiting hole 55, the lock is released, and the telescopic shaft 52 switches to the second state. In other embodiments, the second inclined guide rail and Fig.14 and Fig.15 The depth distribution shown in the figure is in the opposite direction. At this time, the knob is turned counterclockwise to force the telescopic shaft into the limiting hole. When the knob is turned clockwise, the telescopic shaft is separated from the limiting hole under the spring rebound.

[0130] After the second knob is rotated into position, the second knob needs to be circumferentially limited to limit the second knob from spontaneously rotating without external force. A preferred limiting method is to set second circumferential limiting grooves 51b at both ends of the second inclined guide rail 51a. The force-applying end of the telescopic shaft 52 slides into the second circumferential limiting groove 51b to achieve circumferential limiting of the second knob 51 and the telescopic shaft 52. In other embodiments, the second knob can also be circumferentially limited by other methods, such as setting mutually cooperating limiting members on the second knob and the corresponding positions on the outer surface of the shoulder strap carrier, and circumferential limiting is achieved by the cooperation between the second knob and the upper limiting member on the shoulder strap carrier; the two limiting methods can also be used in combination.

[0131] The telescopic shaft 52 is installed through the strap carrier. In one embodiment, a groove 56 is provided on the strap carrier 20 (see Fig.16 ), the groove is recessed inward relative to the outer surface of the shoulder strap carrier, the telescopic shaft 52 is installed through the bottom of the groove, the force-applying end of the telescopic shaft and the part with the spring stopper are located in the groove 56, one end of the second spring 54 abuts against the spring stopper 53, and the other end abuts against the bottom of the groove 56.

[0132] The second knob is rotationally connected to the shoulder carrier. During the rotation of the second knob, the second knob is supported by the surface of the shoulder carrier and applies force to the telescopic shaft through its inclined guide rail. In one embodiment, a mounting hole 27 is provided on the shoulder carrier 10 and near the groove 56. The mounting shaft (not marked in the figure) is fixedly connected to the shoulder carrier through the mounting hole. The second knob 51 is coaxially inserted into the mounting shaft and rotatably cooperates with the mounting shaft. The surface where the inner edge of the second knob is located is supported by the surface of the shoulder carrier. The mounting shaft is provided with an axial limit cap to limit the axial movement of the knob.

[0133] The mode selection module 50 can be arranged at any height of the vertical frame of the carrying system. In one embodiment, the mode selection module 50 is arranged at the side close to the bottom of the suspended carrying system.

[0134] The balance adjustment module 60 is used to adjust the elastic force of the elastic rope, which can be achieved by a variety of adjustment methods, such as a rotating shaft mechanism, a ratchet mechanism, etc. In one embodiment, the balance adjustment module 60 adopts a step-by-step adjustment mechanism. Further, the balance adjustment module 60 includes a bidirectional ratchet mechanism installed on the strap carrier 10 and a chuck 63 driven synchronously by the bidirectional ratchet mechanism. The chuck has an annular groove 63b for the elastic rope to be wound around, and the elastic rope is tightly fitted into the annular groove of the chuck. Tight fit can be understood as the elastic rope can be inserted into or out of the annular groove as the chuck rotates, and the elastic rope is inserted into the annular groove when the chuck is fixed and does not slide relative to the annular groove.

[0135] As an implementation method of the bidirectional ratchet mechanism, the bidirectional ratchet mechanism is as follows: Figures 17 to 20As shown, it includes: an adjusting wrench 61, a ratchet 62, a positioning shaft 65, a toggle pawl 67, a first torsion spring 68, an adjusting column 69, a limiting pawl 610 and a second torsion spring 611. The positioning shaft 65 is fixed to the strap carrier 10, and the positioning shaft is installed perpendicular to the inner surface of the strap carrier. The adjusting wrench 61, the ratchet 62 and the chuck 63 are sequentially sleeved on the positioning shaft 65 and rotated with the positioning shaft. The adjusting wrench 61 includes a wrench head and a wrench handle. The wrench head is installed on the positioning shaft, and the wrench handle extends out of the strap carrier for easy operation. The adjusting wrench 61, the ratchet 62 and the chuck 63 are limited to move axially along the positioning shaft by a fastener installed on the positioning shaft 69.

[0136] The adjusting wrench 61 and the ratchet 62 can rotate relative to each other, and the ratchet 62 and the chuck 63 are relatively fixed. The ratchet and the chuck rotate synchronously. The chuck 63 has an annular groove 63b surrounding the chuck circumference. The elastic rope 62 passes around the chuck 63 and is installed in the annular groove, and is tightly fitted with the groove. The toggle pawl 67 is rotatably installed on the wrench head of the adjusting wrench. One end of the toggle pawl 67 contacts and cooperates with the ratchet teeth of the ratchet 62, and the other end of the toggle pawl 67 abuts and cooperates with the first torsion spring. The first torsion spring 68 is rotatably installed on the wrench head or the shoulder strap carrier. One end of the torsion spring abuts and cooperates with the end of the toggle pawl, and the other end is fixed to the wrench head or the shoulder strap carrier. Fig.16 In the embodiment shown, the first torsion spring is mounted on the wrench head and cooperates with the toggle pawl to provide a force point for the toggle pawl. The limit pawl 610 is rotatably mounted on the wrench head and is spaced at a certain angle from the toggle pawl 67 with the positioning axis as the center. One end of the limit pawl contacts and cooperates with the ratchet teeth of the ratchet wheel, and the other end of the limit pawl 610 abuts and cooperates with the second torsion spring. The second torsion spring is rotatably mounted on the wrench head or the strap carrier, and one end of the second torsion spring abuts and cooperates with the end of the limit pawl. Fig.18 and Fig. 20 In the embodiment shown, the second torsion spring is mounted on the strap carrier, that is, Fig.21 The second torsion spring is shown at the mounting point 14. An adjustment column 69 is arranged on the wrench head and between the toggle pawl and the limit pawl. The adjustment column 69 is vertically fixed on the wrench head. When the adjustment wrench is toggled in one direction, the adjustment wrench rotates until the adjustment column abuts against the limit pawl and then continues to apply force to disengage the limit pawl from the ratchet.

[0137] As a specific implementation of the tight fit, the two opposite inner side walls in the annular groove are staggeredly arranged along the circumference of the annular groove 63b; the surface of the block in contact with the elastic cord is provided with an arc groove adapted to the elastic cord. The elastic cord is inserted into the annular groove 63b by the staggered arrangement of the block 63c, so that the elastic cord and the annular groove are tightly fitted, so that the chuck and the elastic cord do not move relative to each other.

[0138] The elastic rope tightening process: turn the handle of the adjusting wrench so that the pawl applies force to the ratchet to rotate the ratchet, driving the chuck to rotate synchronously, and tightening the elastic rope; the elastic rope loosening process: turn the handle of the adjusting wrench in the opposite direction, and the adjusting wrench is rotated until the adjusting column abuts against the limit pawl to apply force to the limit pawl, so that the limit pawl disengages from the ratchet, and the ratchet rotates in the opposite direction under the tension of the elastic rope at the fixed pulley end, driving the chuck to rotate in the opposite direction synchronously, and loosening the elastic rope.

[0139] The fastener is used to limit the axial movement of the adjusting wrench, ratchet and chuck. In a specific embodiment, the fastener includes a fastening ring 64 and a fastening nut 66. The fastening ring 64 is sleeved on the positioning shaft and abuts against the chuck 63. The fastening nut 66 is detachably connected to the end of the positioning shaft 65.

[0140] The rotation of the ratchet 62 drives the chuck 63 to rotate synchronously. As a specific embodiment of the relative fixation of the ratchet and the chuck, a positioning hole 62a is provided on the ratchet 32, and a shaft column 63a matching the positioning hole 62a is provided on the chuck 63. The shaft column 63a extends into the positioning hole 62a to limit the relative movement between the ratchet and the chuck. In other embodiments, the ratchet and the chuck can also be integrally arranged.

[0141] The fixed end of the elastic cord 32 is provided with a freely adjustable elastic cord section after passing through the chuck. In one embodiment, in order to better store the section of the elastic cord in the carrying system, an elastic cord tube 33 is further provided on the shoulder strap carrier, and the elastic cord 32 passes through the elastic cord tube 33 after passing through the chuck; an elastic cord guide buckle 36 is provided on the shoulder strap carrier and along the path where the elastic cord 32 passes from the chuck 63 into the elastic cord tube 33, so as to better guide the elastic cord during the adjustment process.

[0142] When adjusting the elastic force of the elastic rope, the operation is performed through the spanner handle. In order to facilitate the operation of the spanner handle, in one embodiment, the side of the strap carrier 10 is provided with an avoidance hole (not marked in the figure) for the spanner handle to pass through. The spanner handle passes through the avoidance hole and extends outside the strap carrier, which is convenient for operation.

[0143] In other embodiments, the suspension adjustment module 50 may also adopt a shock absorbing adjustment mechanism as in CN 110720737A.

[0144] In order to better exert the suspension ability of the suspension connection module and better adjust the elastic force of the elastic cord, in one embodiment, the balance adjustment module 60 is arranged near the bottom of the shoulder strap carrier 10; the suspension end of the elastic cord is fixed near the bottom of the load carrier 20, that is, the fixed end and the suspension end of the elastic cord are both installed near the bottom of the carrying system. Correspondingly, the elastic cord tube is horizontally arranged near the top of the shoulder strap carrier, and the fixed end of the elastic cord bypasses the clamp of the balance adjustment module and extends vertically to penetrate into the elastic cord tube. The elastic cord guide buckle 34 is distributed on the elastic cord section between the balance adjustment module and the entrance of the elastic cord sleeve.

[0145] The shoulder strap carrier and the sliding carrier are slidably matched, and a sliding assembly that cooperates with each other is provided between the shoulder strap carrier and the load carrier. The sliding assembly can be realized in a variety of ways. In one embodiment, the sliding assembly includes a slide rail 12 provided on the shoulder strap carrier and a plurality of guide pulleys 22 provided on the load carrier and slidably matched with the slide rail. The guide pulleys 22 are arranged in pairs, and the slide rail can slide along the slide rail when inserted between two guide pulleys. The slide rail is arranged on the two vertical side edges of the shoulder strap carrier, and the corresponding two vertical side edges on the load carrier are connected to the slide rail from both sides of the shoulder strap carrier in the form of hemming. The guide pulleys are arranged in pairs on the inner side of the side edge of the load carrier, and the slide rail is inserted between the guide pulley pairs to realize the sliding match between the shoulder strap carrier and the sliding carrier.

[0146] In order to further enhance the strength of the load carrier and the back load body, an auxiliary slide rail is provided on the back carrier. The auxiliary slide rail is located on the inner surface of the back carrier and is arranged vertically. A pair of guide pulleys are arranged on the inner surface of the load carrier and at intervals corresponding to the auxiliary slide rail. The axial direction of the guide pulley pair is perpendicular to the inner surface of the back carrier. The auxiliary slide rail is inserted between the guide pulley pair to further enhance the sliding stability of the load carrier and the back load body.

[0147] The load carrier slides up and down along the guide rail. In one embodiment, a limiter 13 is set at the bottom end of the inner side of the shoulder strap carrier. The limiter is used to limit the downward movement of the load carrier. The limiter can be set as a protrusion protruding outward relative to the inner surface of the shoulder strap carrier.
