Description

Technical Field

[0001] The present invention relates to the technical field of outdoor power generation equipment, and in particular to a power generation mechanism, outdoor power generation equipment and an outdoor power generation method. Background Art

[0002] Outdoor power generation equipment refers to equipment that can generate electricity in outdoor environments and is used to provide power supply for mobile devices, lighting equipment, communication equipment, etc. For example, solar charging panels, wind turbines, fuel generators, hand-cranked generators, etc. can all be used in the field of outdoor power generation.

[0003] However, these devices are often large in size and complex in structure. They are not convenient to carry for short-term outdoor activities such as camping and exploring. In particular, hand-cranked generators require the human body to manually turn the crank of the generator to generate electricity, which consumes additional physical strength.

[0004] At present, various devices that use human body movement to generate electricity have appeared in the prior art, such as generating electricity by walking, generating electricity by joint movement, etc. Among them, the power generation equipment that uses walking to generate electricity often uses linear motion to generate electricity for the generator. However, since the amplitude of relative movement between the generator and the human body is small, and the volume of the power generation equipment itself is limited by the volume that the human body can withstand, the power generation efficiency of using linear motion to pull the generator is low under limited volume.

[0005] If you want to improve the power generation efficiency, you need to use multiple generators to improve the power generation efficiency of the entire mechanism. However, the power generation equipment in this case often has a complex structure and is too heavy, which not only increases the weight of the entire device, but also increases the burden on the user. Moreover, the complex structure requires professional knowledge and skills for maintenance and adjustment, which makes it difficult for users who do not have professional knowledge and skills to maintain it during use.

[0006] Therefore, it is necessary to improve the structure of the existing power generation equipment that uses human movement to generate electricity so that it can be applied to the field of outdoor power generation. At the same time, it can also solve the technical problems in the prior art that the outdoor power generation equipment has a complex structure, large size, and low power generation efficiency, resulting in low applicability of the outdoor power generation equipment. Summary of the invention

[0007] The purpose of the present invention is to provide a power generation mechanism, outdoor power generation equipment and outdoor power generation method, which can be applied to the field of outdoor power generation, and solve the technical problems in the prior art that outdoor power generation equipment has a complex structure, a large size, and a low power generation efficiency, resulting in low applicability of outdoor power generation equipment.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] In the first aspect, the present invention discloses a power generation mechanism, including a generator, wherein the generator has a generator shaft, the generator shaft can rotate and drive the generator to generate electricity, a transmission gear is fixed on the generator shaft, the transmission gear is transmission-connected to a winding wheel, the winding wheel includes a winding gear, and the winding gear is meshed with the transmission gear; one end of a winding rope is fixed to the winding wheel, the winding rope is wound around the winding wheel, and an external force pulls the other end of the winding rope to drive the winding wheel to rotate, and then the winding wheel can drive the transmission gear to rotate, and the transmission gear drives the generator to generate electricity.

[0010] The present invention uses a wire transmission method to convert a long-stroke linear motion into a short-stroke reciprocating motion by winding a wire.

In this way, when the external force alternately pulls the other ends of the first winding rope and the second winding rope, the first winding rope and the second winding rope drive the winding wheel to rotate in the same direction, and then the first transmission gear and the second transmission gear rotate in the same direction, realizing the one-way rotation of the generator shaft, which can avoid the generation of a large reverse torque when the generator rotates in both directions.

In this way, the first winding rope and the second winding rope are distributed in the first winding groove and the second winding groove, which can realize the function of avoiding de-wirement. When the winding wheel rotates, they can rotate independently, thereby avoiding the problem of mutual entanglement between the first winding rope and the second winding rope as much as possible.

[0014] In the second aspect, the present invention also discloses an outdoor power generation equipment, which utilizes the power generation mechanism as described above, including a first mounting plate and a second mounting plate, wherein the first mounting plate and the second mounting plate are arranged opposite and parallel to each other; the generator is fixed to one side of the first mounting plate, and the first mounting plate has an opening, and the generator shaft passes through the opening and extends toward the second mounting plate, and the generator shaft can rotate in the opening, and the first transmission gear and the second transmission gear are both fixed on the generator shaft located on the other side of the first mounting plate; the winding wheel is located on the other side of the first mounting plate, and is rotatably connected to the first mounting plate; the first winding rope and the second winding rope are both fixed at one end away from the winding wheel to the side of the second mounting plate facing the first mounting plate.

[0015] In this way, during the specific implementation, the external force causes relative movement between the first mounting plate and the second mounting plate, and the winding rope on the winding wheel can drive the winding wheel to rotate, and then the winding wheel can drive the first transmission gear and the second transmission gear to rotate, and the first transmission gear and the second transmission gear drive the generator to generate electricity.

[0016] As a preferred solution for outdoor power generation equipment, in order to further increase the stroke of the wire transmission, that is, the stroke of the first winding rope and the second winding rope, a first pulley assembly is arranged on the first winding rope, and the first winding rope passes through the first pulley assembly; a second pulley assembly is arranged on the second winding rope, and the second winding rope passes through the second pulley assembly; the first pulley assembly and the second pulley assembly are both installed on the side of the first mounting plate facing the second mounting plate, and the first pulley assembly and the second pulley assembly are distributed on both sides of the winding wheel; the direction in which the first winding rope is wound on the first pulley assembly is opposite to the forward and reverse directions in which the second winding rope is wound on the second pulley assembly. In this way, the winding stroke can be increased within a limited space, and the occupied area of ​​the power generation mechanism in the outdoor power generation equipment is ensured to be small, and the power generation efficiency can be improved, and the scope of application of the outdoor power generation equipment can be improved.

[0017] As a preferred scheme for the power generation method of outdoor power generation equipment, the first mounting plate and the second mounting plate are vertically arranged, and a fixing device is arranged on the second mounting plate, and the fixing device is fixed to the human body, that is, the regular vibration of the human body during movement can be utilized to make the first mounting plate move relative to the second mounting plate, thereby realizing the power generation of the power generation mechanism, and because two winding ropes are arranged on the winding wheel, it can be achieved that when the first mounting plate vibrates vertically upward or vertically downward, it can drive the generator to generate electricity, thereby improving the power generation efficiency.

On the one hand, the vibration reduction mechanism can limit the amplitude of the first mounting plate, so that the tension of the winding rope during movement is limited to prevent damage to the winding rope; on the other hand, the vibration intensity of the first mounting plate can be reduced through the elastic buffering effect of the elastic member, thereby reducing the impact of the weight on the human body and improving walking comfort.

[0020] On the third aspect, the present invention also discloses an outdoor power generation method, which uses the outdoor power generation equipment as described above, fixes the second mounting plate of the outdoor power generation equipment to the back of the human body, fixes a storage bag on the first mounting plate of the outdoor power generation equipment, and puts items in the storage bag.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invention product is usually placed when used, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In addition, the terms "horizontal", "vertical", etc. do not mean that the components are absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The present invention can be applied to the field of outdoor power generation, and solves the technical problem in the prior art that outdoor power generation equipment has a complex structure, a large volume, and a low power generation efficiency, resulting in low applicability of the outdoor power generation equipment.

[0041] First, see Figure 1 Based on the technical problems solved above, the present invention discloses a power generation mechanism 100, including a generator 105, wherein the generator 105 has a generator shaft 108, wherein the generator shaft 108 can rotate and drive the generator 105 to generate electricity, wherein a transmission gear is fixed on the generator shaft 108, wherein the transmission gear is transmission-connected to a winding wheel 109, wherein the winding wheel 109 includes a winding gear, wherein the winding gear is meshed with the transmission gear;

[0042] One end of a winding rope is fixed on the winding wheel 109, and the winding rope is wound on the winding wheel 109. External force pulls the other end of the winding rope to drive the winding wheel 109 to rotate, and then the winding wheel 109 can drive the transmission gear to rotate, and the transmission gear drives the generator 105 to generate electricity.

[0043] The present invention uses a wire transmission method to convert a long-stroke linear motion into a short-stroke reciprocating motion by winding a wire. The energy capture mechanism composed of the winding wheel 109, the transmission gear, the generator 105 and other components will convert the mechanical energy of this part of the displacement difference into electrical energy. At the same time, the present invention uses the winding wheel 109 to act as an amplifying gear and mesh with the transmission gear on the generator shaft 108 to achieve an amplification effect, amplify the stroke of the wire transmission method, and solve the technical problem of low applicability of outdoor power generation equipment in the prior art due to its complex structure, large size, and low power generation efficiency.

[0044] In the prior art, the amplification mechanism of the linear transmission using gears for amplification can achieve force amplification or speed reduction through the meshing relationship of the gear mechanism. The gear mechanism is composed of gears and gear pairs. The gears have a certain number of teeth and tooth profiles, and the gear pairs are gears meshing with them, having the same or different numbers of teeth. When the two gears are meshed, the output gear can be rotated at a certain speed and torque by rotating the input gear. In power generation equipment, the gear structure is generally used to convert low-speed and high-torque inputs into high-speed and low-torque outputs to increase the speed and efficiency of the generator 105. Through appropriate gear pairing, force amplification and speed reduction can be achieved, thereby meeting the working requirements of the generator 105.

[0045] As for the wire transmission form using gears for amplification, the present invention adopts the winding wheel 109 which also acts as the amplifying gear in the amplifying mechanism, thereby simplifying the equipment, reducing the complexity of the equipment, reducing the volume of the power generation mechanism 100, and improving the power generation efficiency.

[0046] As a preferred solution of the power generation mechanism 100, one end of a first winding rope 111 and a second winding rope 122 are respectively fixed on the winding wheel 109, and the first winding rope 111 and the second winding rope 122 are respectively wound around the winding wheel 109; external force alternately pulls the other ends of the first winding rope 111 and the second winding rope 122, which can respectively drive the winding wheel 109 to rotate, and then the winding wheel 109 can drive the transmission gear to rotate, and the transmission gear drives the generator 105 to generate electricity.

[0047] As one embodiment of the winding direction of the power generation mechanism 100, the first winding rope 111 and the second winding rope 122 are wound in opposite directions on the winding wheel 109. In this way, when the external force alternately pulls the other ends of the first winding rope 111 and the second winding rope 122, the generator 105 rotates in opposite directions to generate electricity.

[0048] According to one of the above embodiments of the winding direction of the power generation mechanism 100, if the generator 105 needs to change the direction during the power generation process, a large torque is often required, which may hinder the entire mechanism. The continuous reciprocating motion of the generator 105 may cause kinetic energy loss, thereby reducing the power generation efficiency. Then, as a preferred solution for the winding direction of the power generation mechanism 100, the winding direction of the second winding rope 122 in the second winding groove 116 is consistent with the winding direction of the first winding rope 111 in the first winding groove 115, and a one-way bearing is installed between the first transmission gear 106, the second transmission gear 107 and the generator shaft 108.

[0049] In this way, when external force alternately pulls the other ends of the first winding rope 111 and the second winding rope 122, the first winding rope 111 and the second winding rope 122 drive the winding wheel 109 to rotate in the same direction, and then the first transmission gear 106 and the second transmission gear 107 rotate in the same direction, realizing unidirectional rotation of the generator shaft 108, and avoiding the generation of a large reverse torque when the generator 105 rotates in both directions.

[0050] If the transmission efficiency of the entire power generation mechanism 100 is to be further improved, the stroke of the wire transmission method needs to be amplified. In the prior art, the mechanism design for amplifying the stroke of the wire transmission method is too complicated. The present invention improves this by making the winding wheel 109 also act as the large gear in the amplification mechanism and mesh with the transmission gear on the generator shaft 108 to achieve the amplification effect. As a preferred solution of the winding wheel 109, please refer to Figure 3 The winding wheel 109 includes a first winding gear 112, a second winding gear 113 and a third winding wheel 114, wherein a first winding groove 115 is provided between the first winding gear 112 and the second winding gear 113, and the first winding rope 111 can be wound in the first winding groove 115; the second winding gear 113 and the third winding wheel 114 have a second winding groove 116, and the second winding rope 122 can be wound in the second winding groove 116; correspondingly, for the preferred embodiment of the above-mentioned winding wheel 109, the transmission gear includes a first transmission gear 106 and a second transmission gear 107, wherein the first transmission gear 106 and the second transmission gear 107 are fixedly connected to the generator shaft 108 via a one-way bearing respectively, and when the first transmission gear 106 and the second transmission gear 107 rotate, the generator shaft 108 can be driven to rotate, thereby driving the generator 105 to generate electricity. With this arrangement, the first winding rope 111 and the second winding rope 122 are distributed in the first winding groove 115 and the second winding groove 116, which can achieve the function of avoiding derailment. When the winding wheel 109 rotates, they can rotate independently, thereby avoiding the problem of mutual entanglement between the first winding rope 111 and the second winding rope 122 as much as possible.

[0051] For details, please refer to Figure 3 and Figure 4 A winding wheel shaft mounting hole 117 is opened in the middle of the winding wheel 109, and a winding wheel shaft 110 is mounted in the winding wheel shaft mounting hole 117. The winding wheel shaft 110 is rotatably connected to the first mounting plate 201.

[0052] The use of the power generation mechanism 100 disclosed in the present invention has the following technical effects: the power generation mechanism 100 used in the present invention is a combination of linear transmission and gear group meshing. As for the weight of the whole machine, the use of linear transmission has a simpler and lighter structure, which can effectively reduce the weight, thereby reducing the burden of the whole machine on the human body. The use of linear transmission can also realize the conversion of linear motion into rotary motion, which can improve the power generation efficiency.

[0053] Second, see Figures 2 to 10 The present invention also discloses an outdoor power generation device, using the power generation mechanism 100 as described above, including a first mounting plate 201 and a second mounting plate 202, wherein the first mounting plate 201 and the second mounting plate 202 are arranged oppositely and in parallel;

[0054] The generator 105 is fixed to one side of the first mounting plate 201. The first mounting plate 201 has an opening. The generator shaft 108 passes through the opening and extends toward the second mounting plate 202. The generator shaft 108 can rotate in the opening. The first transmission gear 106 and the second transmission gear 107 are both fixed to the generator shaft 108 located on the other side of the first mounting plate 201.

[0055] The winding wheel 109 is located on the other side of the first mounting plate 201 and is rotatably connected to the first mounting plate 201; the ends of the first winding rope 111 and the second winding rope 122 away from the winding wheel 109 are both fixed to the side of the second mounting plate 202 facing the first mounting plate 201.

[0056] In this way, during the specific implementation, the external force causes relative movement between the first mounting plate 201 and the second mounting plate 202, and the winding rope on the winding wheel 109 can drive the winding wheel 109 to rotate, and then the winding wheel 109 can drive the first transmission gear 106 and the second transmission gear 107 to rotate, and the first transmission gear 106 and the second transmission gear 107 drive the generator 105 to generate electricity.

[0057] Outdoor power generation equipment can solve the technical problems of difficult outdoor power generation and low power generation efficiency. It can recycle excess energy for power generation during outdoor sports, making full use of relevant resources. It can improve resource utilization while facilitating outdoor electricity use.

[0058] Specifically, the generator 105 is fixed to the first mounting plate 201 through a mounting piece, a screw hole is provided on the mounting piece, the mounting piece is fixedly connected to the first mounting plate 201 by screws, an opening is provided at the center of the mounting piece, and a corresponding opening is also provided on the first mounting plate 201, and the generator shaft 108 passes through the opening toward the direction of the second mounting plate 202.

[0059] Specifically, a winding wheel 109 shaft mounting hole is opened in the middle of the winding wheel 109 , and the winding wheel 109 shaft is mounted in the winding wheel 109 shaft mounting hole. The winding wheel 109 shaft is rotatably connected to the first mounting plate 201 .

[0060] For details, please refer to Figure 3 One end of the first winding rope 111 away from the winding wheel 109 is fixed to the second mounting plate 202 through the first fixing member 103, and one end of the second winding rope 122 away from the winding wheel 109 is fixed to the second mounting plate 202 through the second fixing member 104; specifically, the first fixing member 103 and the second fixing member 104 are both fixed to the second mounting plate 202 by screws.

[0061] As a preferred solution for outdoor power generation equipment, please refer to Figure 3 In order to further increase the stroke of the wire transmission, that is, the stroke of the first winding rope 111 and the second winding rope 122, a first pulley assembly 101 is arranged on the first winding rope 111, and the first winding rope 111 passes through the first pulley assembly 101; a second pulley assembly 102 is arranged on the second winding rope 122, and the second winding rope 122 passes through the second pulley assembly 102; the first pulley assembly 101 and the second pulley assembly 102 are both installed on the side of the first mounting plate 201 facing the second mounting plate 202, and the first pulley assembly 101 and the second pulley assembly 102 are distributed on both sides of the winding wheel 109; the direction in which the first winding rope 111 is wound on the first pulley assembly 101 is opposite to the forward and reverse directions in which the second winding rope 122 is wound on the second pulley assembly 102.

[0062] In this way, the winding stroke can be increased within a limited space, ensuring that the occupied area of ​​the power generation mechanism 100 in the outdoor power generation equipment is small, and the power generation efficiency can be improved, thereby increasing the application range of the outdoor power generation equipment.

[0063] When the first mounting plate 201 vibrates, relative movement occurs between the first mounting plate 201 and the second mounting plate 202, that is, the first mounting plate 201 can vibrate back and forth between the vertical positive direction and the vertical negative direction relative to the second mounting plate 202 in a trajectory similar to a simple harmonic wave. At this time, the first winding rope 111 and the second winding rope 122 will be straightened alternately with the vibration of the first mounting plate 201. When straightened, the winding wheel 309 rotates, thereby driving the first transmission gear 106 and the second transmission gear 107 to rotate, thereby driving the generator shaft 108 to rotate, and then driving the generator 105 to generate electricity.

[0064] For details, please refer to Figure 3 The first pulley assembly 101 includes a first pulley 118, the first pulley 118 has a first wheel groove 120, the first wheel groove 120 is V-shaped or U-shaped, the first winding rope 111 passes through the first wheel groove 120 and is wound on the first winding groove 115 of the winding wheel 109, and the radial sections of the first wheel groove 120 and the first winding groove 115 are located on the same plane; the second pulley assembly 102 includes a second pulley 119, the second pulley 119 has a second wheel groove 121, the second winding rope 122 passes through the second wheel groove 121 and is wound on the second winding groove 116 of the winding wheel 109, and the radial sections of the second wheel groove 121 and the second winding groove 116 are located on the same plane. In this way, the existence of the winding groove can achieve the function of preventing derailment.

[0065] Thus, according to the characteristics of the linear transmission, if the transmission system is bent, deflected or incorrectly aligned, it will cause interference, friction and premature wear between the transmission parts. Therefore, ensuring that the radial cross-sections of the first wheel groove 120 and the first winding groove 115 are located on the same plane, and the radial cross-sections of the second wheel groove 121 and the second winding groove 116 are located on the same plane, helps to reduce friction, noise and energy loss in the transmission, and improves the efficiency and reliability of the transmission.

[0066] As a specific implementation scheme of the power generation method of outdoor power generation equipment, the first mounting plate 201 and the second mounting plate 202 are arranged horizontally or vertically; for the horizontally arranged power generation method, when generating electricity, the external force causes the first mounting plate 201 and the second mounting plate 202 to move relative to each other in the horizontal direction, so that power generation can be achieved. The external force can be human, mechanical, etc. However, under outdoor conditions, human resources are limited, and mechanical resources are also limited. This power generation method occupies a large amount of human resources. Therefore, as a preferred solution for the power generation method of outdoor power generation equipment, please refer to Figure 7The first mounting plate 201 and the second mounting plate 202 are arranged vertically, and a fixing device is arranged on the second mounting plate 202, and the fixing device is fixed to the human body, that is, the regular vibration of the human body during movement can be utilized to make the first mounting plate 201 move relative to the second mounting plate 202, thereby realizing the power generation of the power generation mechanism 100. Moreover, since two winding ropes are arranged on the winding wheel 109, it can be achieved that when the first mounting plate 201 vibrates vertically upward or vertically downward, it can drive the generator 105 to generate electricity, thereby improving the power generation efficiency.

[0067] As a preferred solution of the outdoor power generation equipment, a storage bag is provided on the first mounting plate 201, in which articles can be placed, and the storage bag is detachably connected or fixedly connected to the first mounting plate 201. The detachable storage bag can be a plastic bag, a canvas bag, etc., and the specific detachable method is to provide a hook on the first mounting plate 201 and hang the detachable storage bag on the first mounting plate 201. The specific implementation method of the fixed storage bag is to fix the storage bag to the first mounting plate 201 by gluing or nailing.

[0068] As for the preferred scheme of the power generation method of the outdoor power generation equipment, due to the influence of the weight of the first mounting plate 201 and the power generation mechanism 100 itself and the weight of the items in the storage bag, the center of gravity of the first mounting plate 201 shifts downward and gradually approaches the center of gravity of the human body. Therefore, when the human body moves, the amplitude of the vertical up and down vibration of the first mounting plate 201 relative to the second mounting plate 202 is not high, and the efficiency of converting the relative displacement between the outdoor power generation equipment and the center of gravity of the human body into mechanical energy and then into electrical energy through the energy capture mechanism will be reduced. In order to make the first mounting plate 201 have a more regular vibration in the vertical direction relative to the second mounting plate 202 and to maintain a relatively high amplitude, it is ensured that the center of gravity of the first mounting plate 201 can always be at an appropriate height under different load conditions, so as to capture more electrical energy. As a preferred scheme of the power generation mechanism 100, please refer to Figure 8 and Fig.10 The outdoor power generation equipment also includes an adjustable mechanism 400; the adjustable mechanism 400 includes a first end seat 401 and a second end seat 402, the first end seat 401 is fixed on the first mounting plate 201, the second end seat 402 is fixed on the second mounting plate 202, a plurality of corresponding through holes are respectively opened on the first end seat 401 and the second end seat 402, a guide column is fixedly connected in each through hole, two ends of the guide column respectively extend into the corresponding through holes opened on the first end seat 401 and the second end seat 402, and a tuning spring is sleeved on the outer peripheral side of the guide column located between the first end seat 401 and the second end seat 402.

[0069] In this way, when the user exercises, supported by the limited elastic compression deformation of the tuning spring, the center of gravity of the first mounting plate 201 drops only a limited amount, so that its center of gravity can be maintained at a suitable height. This ensures that the center of gravity of the first mounting plate 201 is always at an appropriate height under different load conditions, thereby capturing more electrical energy.

[0070] As a preferred embodiment of the tunable mechanism 400, please refer to Fig.10 , a total of five groups of corresponding through holes are evenly distributed on the first end seat 401 and the second end seat 402 of the tunable mechanism 400, wherein one group of corresponding through holes is opened at the center of the first end seat 401 and the second end seat 402, and a central guide column 405 is fixedly connected in this group of through holes, and the central guide column 405 has an extension section, and the extension section extends from the first end seat 401 toward a direction away from the second end seat 402, and a central tuning spring 410 is sleeved on the extension section, and the end of the central guide column 405 away from the first end seat 401 has a blocking block for preventing the central tuning spring 410 from falling off from the extension section;

[0071] The other four groups of corresponding through holes are respectively fixedly connected with the first guide column 403, the second guide column 404, the third guide column 406 and the fourth guide column 407, and the outer peripheral sides of the first guide column 403, the second guide column 404, the third guide column 406 and the fourth guide column 407 located between the first end seat 401 and the second end seat 402 are respectively sleeved with the first tuning spring 408, the second tuning spring 409, the third tuning spring 411 and the fourth tuning spring 412.

[0072] Specifically, the first end seat 401 is provided with a plurality of first connecting members 413, and the first end seat 401 is fixed to the first mounting plate 201 through the plurality of first connecting members 413. The first connecting member 413 has a plane facing the first mounting plate 201, and there is an opening on the plane. The corresponding mounting position of the corresponding first mounting plate 201 also has an opening, and screws are screwed into the openings to achieve fixed connection between the first connecting member 413 and the first mounting plate 201. Setting the side of the first connecting member 413 facing the first mounting plate 201 as a plane is conducive to the fit between the first end seat 401 and the first mounting plate 201, so that the contact surface is larger and the fixation is more firm.

[0073] Specifically, the second end seat 402 is provided with a plurality of second connecting members 414, and the second end seat 402 is fixed to the second mounting plate 202 through the plurality of second connecting members 414. The second connecting member 414 has a plane facing the second mounting plate 202, and there is an opening on the plane. The corresponding mounting position of the corresponding second mounting plate 202 also has an opening, and screws are screwed into the openings to achieve fixed connection between the second connecting member 414 and the second mounting plate 202. Setting the side of the second connecting member 414 facing the second mounting plate 202 as a plane is conducive to the fit between the second end seat 402 and the second mounting plate 202, so that the contact surface is larger and the fixation is more firm.

[0074] Since outdoor power generation equipment is applied to the human body, it is necessary to reduce the sense of weight on the human body and reduce the impact of vibration of outdoor power generation equipment on the human body from the perspective of human comfort. Therefore, as the preferred solution for outdoor power generation equipment, please refer to Figure 8 and Fig. 9 A vibration reduction mechanism 300 is also installed between the first mounting plate 201 and the second mounting plate 202. The vibration reduction mechanism 300 includes a guide rail 301 and an elastic member. Both ends of the guide rail 301 are fixedly connected to the second mounting plate 202. When the user moves, the elastic member can undergo elastic deformation along the extension direction of the guide rail 301, thereby limiting the amplitude of the first mounting plate 201 relative to the second mounting plate 202.

[0075] On the one hand, the vibration reduction mechanism 300 can limit the amplitude of the first mounting plate 201, so that the tension of the winding rope during movement is limited to prevent the winding rope from being damaged; on the other hand, the vibration intensity of the first mounting plate 201 can be reduced by the elastic buffering effect of the elastic part, thereby reducing the impact of the weight on the human body and improving walking comfort.

[0076] As a preferred solution of the vibration reduction mechanism 300, please refer to Fig. 9 The elastic member of the vibration reduction mechanism 300 is a constant force spring. A second guide rail fixing member 303 is sleeved on the guide rail 301. The second guide rail fixing member 303 is fixed on the first mounting plate 201. The constant force spring includes a first constant force spring 305 and a second constant force spring 306, and is respectively sleeved on the guide rails 301 on both sides of the second guide rail fixing member 303.

[0077] In this way, when the first mounting plate 201 vibrates, the second guide rail fixing member 303 fixed on the first mounting plate 201 can be driven by the first mounting plate 201 to vibrate synchronously. Furthermore, the vibration intensity of the first mounting plate 201 is reduced by the elastic buffering effect of the first constant force spring 305 and the second constant force spring 306, thereby reducing the impact of the weight on the human body and improving walking comfort.

[0078] Specifically, two ends of the guide rail 301 are fixed to the second mounting plate 202 via a first guide rail fixing member 302 and a third guide rail fixing member 304 respectively.

[0079] As a preferred solution of the vibration reduction mechanism 300, please refer to Figure 8 The vibration reduction mechanism 300 is provided with two and is symmetrically arranged at the positions near the side edges of the first mounting plate 201 and the second mounting plate 202. This can not only enhance the vibration reduction strength and further reduce the impact of the load on the human body, but also make the vibration reduction mechanism 300 more balanced during operation, and the vibration reduction strength is more uniform, further improving the walking comfort.

[0080] Specifically, the first guide rail fixing member 302 and the third guide rail fixing member 304 of each vibration reduction mechanism 300 are fixed on the second mounting plate 202 , and the second guide rail fixing member 303 of each vibration reduction mechanism 300 is fixed on the first mounting plate 201 .

[0081] According to the force movement of the shock absorbing mechanism to the load, a specific dynamic model of constant pressure spring-load-constant pressure spring is established according to Newton's second law. For the load and constant pressure spring system, the following two equations are obtained:

[0082] (1) Partial differential dynamics equation of a heavy object:

[0083]

[0084] In formula (1), m: mass of the load (unit: kg),

[0085] g: acceleration due to gravity, usually 9.8m / s 2 ,

[0086] k1, k2: the stiffness coefficients of the first constant force spring and the second constant force spring respectively (unit: N / m),

[0087] L1, L2: the natural length of the first constant force spring and the second constant force spring respectively (unit: m),

[0088] x1, x2: the deformation of the first constant force spring and the second constant force spring respectively (unit: m),

[0089] y: vertical displacement of the load relative to the reference position of the generating equipment (unit: m),

[0090] c: Damping coefficient, unitless.

[0091] In this equation, the first term represents the force applied by the upper compression spring to the load, the second term represents the force applied by the lower compression spring to the load, the third term represents the effect of gravity on the load, and the last term represents the effect of the equivalent damping coefficient on the velocity, where c damping coefficient is the equivalent damping coefficient integrating the first constant force spring and the second constant force spring with the guide rail. It should be noted that this model assumes that the system is one-dimensional and does not consider other possible factors, such as nonlinear effects and dissipative effects.

[0092] (2) The deformation equation of the constant force spring is as follows:

[0093] x1= (y - L1) / k1 (2)

[0094] x2= (y- L2) / k1 (3)

[0095] In formulas (2) and (3), k1, k2 are the stiffness coefficients of the first constant force spring and the second constant force spring, respectively (unit: N / m),

[0096] L1, L2: the natural length of the first constant force spring and the second constant force spring respectively (unit: m),

[0097] x1, x2: the deformation of the first constant force spring and the second constant force spring respectively (unit: m),

[0098] y: vertical displacement of the load relative to the reference position of the generating equipment (unit: m),

[0099] Equations (2) and (3) represent the relationship between the deformation of the constant force spring and the position of the load.

[0100] Specifically, the generator of the present invention is a linear generator or a rotary generator, wherein the linear generator has a simple structure, is easy to maintain, does not require rotating parts, and has small mechanical losses, but the voltage and power generated by the linear generator are relatively low, and multiple stages need to be connected in series to generate high power. For the present invention, the power generation is limited due to the length of the linear guide rail; the rotary generator can generate higher voltage and power, and there is no reciprocating deceleration process, and the power generation is stable.

[0101] For the present invention, it is preferred to use a rotary generator, specifically an electromagnetic rotary motor.

[0102] The working process of the power generation mechanism 100 of the present invention is: Figure 5 and Figure 6, the observation angle is to observe from the first mounting plate 201, and the subsequent counterclockwise, clockwise, etc. are also described based on this angle. When the first mounting plate 201 descends, the generator 105, the first pulley assembly 101, and the second pulley assembly 102 descend as a whole, causing the second winding rope 122 to be stretched, while the first winding rope 111 is relaxed due to the descent of the pulley. When the second winding rope 122 is stretched, the winding wheel 109 will rotate in the clockwise direction, and the first winding rope 111 will be tightened due to the clockwise rotation of the winding wheel 109; conversely, when the first mounting plate 201 rises, the generator 105, the first pulley assembly 101, and the second pulley assembly 102 rise as a whole, causing the first winding rope 111 to be stretched, and the stretched part includes the first winding rope 111 wound on the winding wheel 109 due to the clockwise rotation of the winding wheel 109 when the first mounting plate 201 descends, and the second winding rope 122 is relaxed due to the rise of the pulley. When the first winding rope 111 is stretched, the winding wheel 109 will rotate in the counterclockwise direction. At this time, the second winding rope 122 will be tightened due to the clockwise rotation of the winding wheel 109. The power generation mechanism 100 can wind up another wire while paying out one wire, which can not only convert the linear reciprocating motion into rotational motion, but also avoid the problem of derailment to a certain extent.

[0103] The power generation principle of the outdoor power generation equipment of the present invention is to convert the relative displacement between the center of gravity of the outdoor power generation equipment and the center of gravity of the human body into mechanical energy and then convert it into electrical energy through an energy capture mechanism. Specifically, when the user exercises with a load, the outdoor power generation equipment is affected by the vibration of the user's body during exercise, and the center of gravity of the weight will also produce vertical up and down displacement, which will cause the first mounting plate to produce synchronous up and down vibration displacement; then, when the first mounting plate produces up and down vibration displacement, the second fixing part in the vibration reduction mechanism fixedly connected to the first mounting plate and the second mounting plate will move vertically up and down along the guide rail, and at the same time stretch or compress the constant force spring on the guide rail, then in the process of releasing or accumulating the elastic force, the power generation mechanism can generate electricity periodically, and at the same time, due to the release or accumulation of the elastic force of the constant force spring, the vibration reduction function can also be realized, which can effectively reduce the impact of the load on the human body and improve walking comfort. Specifically, when the first mounting plate with a storage bag in the power generation mechanism moves vertically up and down, the first winding rope and the second winding rope are stretched alternately. Through the design of the double-groove winding wheel, when the first winding rope is stretched, it drives the winding wheel to rotate. The rotation of the winding wheel drives the rotation of the transmission gear meshing with it, and then drives the motor shaft to rotate, thereby generating electricity. At the same time, the second winding rope will be wound into the winding groove of the winding wheel to keep the two winding ropes in a taut state at all times to prevent them from being derailed or entangled with each other. In order to maintain the power generation force at a high level, a tunable mechanism is also provided. When the user moves, the center of gravity of the first mounting plate is limited to drop under the support of the limited elastic compression deformation of the tuning spring, so that the center of gravity can be maintained at a suitable height. Then, it can be ensured that the center of gravity of the first mounting plate can always be at an appropriate position height under different load conditions, thereby capturing more electrical energy.

[0104] The outdoor power generation equipment disclosed by the present invention has the following technical effects:

[0105] 1. The pulley assembly in the outdoor power generation equipment disclosed in the present invention can amplify the stroke and damping, and can amplify the up and down movement stroke four times to the rotating generator, thereby improving the power generation efficiency. It is connected to the pulley assembly by winding, and the linear motion of the large stroke is converted into the reciprocating motion of the small stroke. When the first mounting plate moves up and down linearly, the energy capture mechanism composed of the winding wheel, transmission gear, generator and other components will convert the mechanical energy of this part of the displacement difference into electrical energy.

[0106] 2. The vibration reduction mechanism in the outdoor power generation equipment disclosed in the present invention can reduce the vibration force of the first mounting plate through the elastic buffering effect of the elastic member, thereby reducing the impact of the load on the human body and improving walking comfort.

[0107] 3. The tunable mechanism in the outdoor power generation equipment disclosed in the present invention can make the first mounting plate have more regular vibration in the vertical direction relative to the second mounting plate and can maintain a relatively high amplitude, ensuring that the center of gravity of the first mounting plate can always be at an appropriate height under different load conditions, thereby capturing more electrical energy.

[0108] 4. Various materials used in the outdoor power generation equipment disclosed in the present invention are made of lighter materials. The thickness of the first mounting plate and the second mounting plate is very thin. The use of a rotating generator also makes the structure of the power generation mechanism simpler, thereby making the outdoor power generation equipment itself light in weight and being able to reduce the burden on the human body during outdoor sports.

[0109] On the third aspect, the present invention also discloses an outdoor power generation method, which uses the outdoor power generation equipment as described above, fixes the second mounting plate of the outdoor power generation equipment to the back of the human body, fixes a storage bag on the first mounting plate of the outdoor power generation equipment, and puts items in the storage bag. Then, the human body walks or runs, the storage bag will vibrate, causing the first mounting plate and the second mounting plate to move relative to each other, thereby causing the power generation mechanism to generate electricity.

[0110] In order to further illustrate the outdoor power generation equipment of the present invention, the present invention discloses the following preferred embodiments.

[0111] Embodiment 1

[0112] The outdoor power generation equipment used in this embodiment can solve the technical problems of difficult outdoor power generation and low power generation efficiency. Figures 1 to 10 , based on the above technical problems to be solved, this embodiment discloses an outdoor power generation device, including a first mounting plate 201 and a second mounting plate 202, wherein the first mounting plate 201 and the second mounting plate 202 are arranged vertically opposite to each other and in parallel;

[0113] The outdoor power generation equipment also includes a power generation mechanism 100, which includes a generator 105. The generator 105 has a generator shaft 108, which can rotate and drive the generator 105 to generate electricity. A transmission gear is fixed on the generator shaft 108, and the transmission gear is connected to a winding wheel 109. The winding wheel 109 includes a winding gear, and the winding gear is meshed with the transmission gear; the generator 105 is fixed to one side of a first mounting plate 201, and the first mounting plate 201 has an opening, and the generator shaft 108 passes through the opening and faces the second mounting plate 20 2 extends, the generator shaft 108 can rotate in the opening, the first transmission gear 106 and the second transmission gear 107 are both fixed to the generator shaft 108 located on the other side of the first mounting plate 201; specifically, the generator 105 is fixed to the first mounting plate 201 through a mounting member, a screw hole is provided on the mounting member, the mounting member is fixedly connected to the first mounting plate 201 through screws, an opening is provided at the center of the mounting member, and an opening is also provided on the corresponding first mounting plate 201, and the generator shaft 108 passes through the opening toward the direction of the second mounting plate 202.

[0114] Specifically, the generator 105 of this embodiment is an electromagnetic rotating motor. The rotating generator 105 can generate a relatively high voltage and power, and has no reciprocating deceleration process and stable power generation.

[0115] Specifically, a fixing device is provided on the second mounting plate 202, and the fixing device is a shoulder strap. By fixing the shoulder strap to the human body, the regular vibration of the human body during movement can be utilized to make the first mounting plate 201 move relative to the second mounting plate 202, thereby realizing the power generation of the power generation mechanism 100. Moreover, since two winding ropes are provided on the winding wheel 109, it can achieve that when the first mounting plate 201 vibrates vertically upward or vertically downward, it can drive the generator 105 to generate electricity, thereby improving the power generation efficiency.

[0116] Specifically, a storage bag is provided on the first mounting plate 201, in which articles can be placed, and the storage bag is detachably connected or fixedly connected to the first mounting plate 201. The detachable storage bag can be a plastic bag, a canvas bag, etc., and the specific detachable manner is to provide a hook on the first mounting plate 201 and hang the detachable storage bag on the first mounting plate 201. The specific implementation manner of the fixed storage bag is to fix the storage bag to the first mounting plate 201 by gluing or nailing.

[0117] Specifically, one end of a winding rope is fixed on the winding wheel 109, and the winding rope is wound on the winding wheel 109. External force pulls the other end of the winding rope, which can drive the winding wheel 109 to rotate, and then the winding wheel 109 can drive the transmission gear to rotate, and the transmission gear drives the generator 105 to generate electricity; the winding wheel 109 is located on the other side of the first mounting plate 201 and is rotatably connected to the first mounting plate 201; the first winding rope 111 and the second winding rope 122 are fixed at one end away from the winding wheel 109 to the side of the second mounting plate 202 facing the first mounting plate 201. One end of a first winding rope 111 and one end of a second winding rope 122 are respectively fixed on the winding wheel 109, and the first winding rope 111 and the second winding rope 122 are respectively wound around the winding wheel 109; external force alternately pulls the other ends of the first winding rope 111 and the second winding rope 122, which can respectively drive the winding wheel 109 to rotate, and then the winding wheel 109 can drive the transmission gear to rotate, and the transmission gear drives the generator 105 to generate electricity.

[0118] For details, please refer to Figure 3 and Figure 4 A winding wheel shaft mounting hole 117 is opened in the middle of the winding wheel 109, and a winding wheel shaft 110 is mounted in the winding wheel shaft mounting hole 117. The winding wheel shaft 110 is rotatably connected to the first mounting plate 201.

[0119] Since the linear transmission can only convert reciprocating linear motion into reciprocating rotary motion. However, during the rotation of the generator 105, if the direction needs to be changed, a large torque is often required, which will hinder the entire mechanism. Therefore, the continuous reciprocating motion of the generator 305 will cause kinetic energy loss, thereby reducing the power generation efficiency. Specifically, the winding direction of the second winding rope 122 in the second winding groove 116 is consistent with the winding direction of the first winding rope 111 in the first winding groove 115, and a one-way bearing is installed between the first transmission gear 106 and the second transmission gear 107 and the generator shaft 108. In this way, when the external force alternately pulls the other end of the first winding rope 111 and the second winding rope 122, the first winding rope 111 and the second winding rope 122 drive the winding wheel 109 to rotate in the same direction, and then the first transmission gear 106 and the second transmission gear 107 have the same rotation direction, realizing the unidirectional rotation of the generator shaft 108, which can avoid the large reverse torque generated when the generator 105 rotates in both directions.

[0120] Specifically, the winding wheel 109 includes a first winding gear 112, a second winding gear 113 and a third winding wheel 114, and a first winding groove 115 is provided between the first winding gear 112 and the second winding gear 113, and the first winding rope 111 can be wound in the first winding groove 115; the second winding gear 113 and the third winding wheel 114 have a second winding groove 116, and the second winding rope 122 can be wound in the second winding groove 116; correspondingly, the transmission gear includes a first transmission gear 106 and a second transmission gear 107, and the first transmission gear 106 and the second transmission gear 107 are respectively fixedly connected to the generator shaft 108 through a one-way bearing, and when the first transmission gear 106 and the second transmission gear 107 rotate, they can drive the generator shaft 108 to rotate, thereby driving the generator 105 to generate electricity. With this arrangement, the first winding rope 111 and the second winding rope 122 are distributed in the first winding groove 115 and the second winding groove 116, which can achieve the function of avoiding derailment. When the winding wheel 109 rotates, they can rotate independently, thereby avoiding the problem of mutual entanglement between the first winding rope 111 and the second winding rope 122 as much as possible.

[0121] Specifically, for the transmission ratio between the first winding gear, the second winding gear, and the first transmission gear and the second transmission gear, this embodiment takes the calculation of the first winding groove, the first winding gear, and the first transmission gear as an example, and the calculation adopted is as follows:

[0122] The diameter of the first winding groove is 50 mm, the modules of the first winding gear and the first transmission gear are both 1, the tooth width is 8, the number of teeth of the first winding gear is 60, and the number of teeth of the first transmission gear is 20. The transmission ratio satisfies the formula:

[0123]

[0124] In formula (4), n1 is the speed of the first winding gear (unit: rad / s), n2 is the speed of the first transmission gear (unit: rad / s), z1 is the number of teeth of the first winding gear, and z2 is the number of teeth of the first transmission gear.

[0125] Because one end of the wire is fixed on the winding wheel, when the wire pulling length is the circumference of the first winding groove, the winding wheel rotates one circle, so the speed of the winding wheel and the wire pulling speed satisfy the formula: v = ω*r, where v is the linear velocity of the winding groove circular motion, that is, the wire pulling speed (unit: m / s), ω is the angular velocity of the winding wheel (unit: rad / s), and r is the radius of the winding groove (unit: m), which is 0.05m. Since the first winding gear also acts as a winding wheel, it satisfies ω = n2 = vr, so the relationship between the motor shaft and the wire pulling speed can be established as n1 = -3n2 = -3vr.

[0126] According to the rated working torque of the motor being 0.04 N·m and the meshing transmission ratio of the first winding gear and the first transmission gear being 1:3, the resistance torque is calculated to be 0.12 N·m.

[0127] A first pulley assembly 101 is arranged on the first winding rope 111, and the first winding rope 111 passes through the first pulley assembly 101; a second pulley assembly 102 is arranged on the second winding rope 122, and the second winding rope 122 passes through the second pulley assembly 102; the first pulley assembly 101 and the second pulley assembly 102 are both installed on the side of the first mounting plate 201 facing the second mounting plate 202, and the first pulley assembly 101 and the second pulley assembly 102 are distributed on both sides of the winding wheel 109; the direction in which the first winding rope 111 is wound on the first pulley assembly 101 is opposite to the forward and reverse directions in which the second winding rope 122 is wound on the second pulley assembly 102. The winding stroke can be increased in a limited space, and the power generation efficiency can be improved while ensuring that the occupied area of ​​the power generation mechanism 100 in the outdoor power generation equipment is small, and the application range of the outdoor power generation equipment can be increased.

[0128] Specifically, a winding wheel 109 shaft mounting hole is opened in the middle of the winding wheel 109 , and the winding wheel 109 shaft is mounted in the winding wheel 109 shaft mounting hole. The winding wheel 109 shaft is rotatably connected to the first mounting plate 201 .

[0129] Specifically, one end of the first winding rope 111 away from the winding wheel 109 is fixed to the second mounting plate 202 via the first fixing member 103, and one end of the second winding rope 122 away from the winding wheel 109 is fixed to the second mounting plate 202 via the second fixing member 104; specifically, the first fixing member 103 and the second fixing member 104 are both fixed to the second mounting plate 202 via screws.

[0130] Specifically, the first pulley assembly 101 includes a first pulley 118, the first pulley 118 has a first wheel groove 120, the first winding rope 111 passes through the first wheel groove 120 and is wound on the first winding groove 115 of the winding wheel 109, and the radial sections of the first wheel groove 120 and the first winding groove 115 are located on the same plane; the second pulley assembly 102 includes a second pulley 119, the second pulley 119 has a second wheel groove 121, the second winding rope 122 passes through the second wheel groove 121 and is wound on the second winding groove 116 of the winding wheel 109, and the radial sections of the second wheel groove 121 and the second winding groove 116 are located on the same plane. In this way, according to the characteristics of the line transmission, if the transmission system is bent, deflected or incorrectly aligned, it will cause interference, friction and premature wear between the transmission parts. Therefore, ensuring that the radial cross-sections of the first wheel groove 120 and the first winding groove 115 are located on the same plane, and the radial cross-sections of the second wheel groove 121 and the second winding groove 116 are located on the same plane helps to reduce friction, noise and energy loss in transmission, and improve transmission efficiency and reliability.

[0131] The outdoor power generation equipment also includes an adjustable mechanism 400; the adjustable mechanism 400 includes a first end seat 401 and a second end seat 402, the first end seat 401 is fixed on the first mounting plate 201, and the second end seat 402 is fixed on the second mounting plate 202, and a plurality of corresponding through holes are respectively opened on the first end seat 401 and the second end seat 402, and a guide column is fixedly connected in each through hole, and both ends of the guide column respectively extend into the corresponding through holes opened on the first end seat 401 and the second end seat 402, and a tuning spring is sleeved on the outer peripheral side of the guide column located between the first end seat 401 and the second end seat 402.

[0132] In this way, when the user exercises, supported by the limited elastic compression deformation of the tuning spring, the center of gravity of the first mounting plate 201 drops only a limited amount, so that its center of gravity can be maintained at a suitable height. This ensures that the center of gravity of the first mounting plate 201 is always at an appropriate height under different load conditions, thereby capturing more electrical energy.

[0133] Specifically, the first end seat 401 and the second end seat 402 of the tunable mechanism 400 are provided with five groups of corresponding through holes evenly distributed, wherein one group of corresponding through holes is provided at the center of the first end seat 401 and the second end seat 402, a central guide column 405 is fixedly connected in the group of through holes, the central guide column 405 has an extension section, the extension section extends from the first end seat 401 in a direction away from the second end seat 402, a central tuning spring 410 is sleeved on the extension section, and the end of the central guide column 405 away from the first end seat 401 has a blocking block for preventing the central tuning spring 410 from falling off the extension section;

[0134] The other four groups of corresponding through holes are respectively fixedly connected with the first guide column 403, the second guide column 404, the third guide column 406 and the fourth guide column 407, and the outer peripheral sides of the first guide column 403, the second guide column 404, the third guide column 406 and the fourth guide column 407 located between the first end seat 401 and the second end seat 402 are respectively sleeved with the first tuning spring 408, the second tuning spring 409, the third tuning spring 411 and the fourth tuning spring 412.

[0135] Specifically, the first end seat 401 is provided with a plurality of first connecting members 413, and the first end seat 401 is fixed to the first mounting plate 201 through the plurality of first connecting members 413. The first connecting member 413 has a plane facing the first mounting plate 201, and there is an opening on the plane. The corresponding mounting position of the corresponding first mounting plate 201 also has an opening, and screws are screwed into the openings to achieve fixed connection between the first connecting member 413 and the first mounting plate 201. Setting the side of the first connecting member 413 facing the first mounting plate 201 as a plane is conducive to the fit between the first end seat 401 and the first mounting plate 201, so that the contact surface is larger and the fixation is more firm.

[0136] Specifically, the second end seat 402 is provided with a plurality of second connecting members 414, and the second end seat 402 is fixed to the second mounting plate 202 through the plurality of second connecting members 414. The second connecting member 414 has a plane facing the second mounting plate 202, and there is an opening on the plane. The corresponding mounting position of the corresponding second mounting plate 202 also has an opening, and screws are screwed into the openings to achieve fixed connection between the second connecting member 414 and the second mounting plate 202. Setting the side of the second connecting member 414 facing the second mounting plate 202 as a plane is conducive to the fit between the second end seat 402 and the second mounting plate 202, so that the contact surface is larger and the fixation is more firm.

[0137] The wire diameter of the first tuning spring, the second tuning spring, the third tuning spring and the fourth tuning spring of this embodiment is 1.5 mm, the outer diameter is 12 mm, the free length is 35 mm, the material is SUP spring steel, and the coefficient is k x=6.14N / mm; the wire diameter of the center tuning spring is 1.0 mm, the outer diameter is 9 mm, the free length is 70 mm, the material is also SUP spring steel, and the elastic coefficient is k d =1.13N / mm. The spacing between the first guide post and the second guide post and between the third guide post and the fourth guide post is 24mm, and the distance between the second guide post and the central guide post and between the third guide post and the central guide post is 27mm.

[0138] Specifically, a vibration reduction mechanism 300 is installed between the first mounting plate 201 and the second mounting plate 202. Two vibration reduction mechanisms 300 are provided and are symmetrically arranged near the side edges of the first mounting plate 201 and the second mounting plate 202. This can not only enhance the vibration reduction strength and further reduce the impact of the load on the human body, but also make the vibration reduction mechanism 300 more balanced during operation, and the vibration reduction strength more uniform, further improving the walking comfort.

[0139] Specifically, the vibration reduction mechanism 300 includes a guide rail 301 and an elastic member, and both ends of the guide rail 301 are fixedly connected to the second mounting plate 202; when the user moves, the elastic member can be elastically deformed along the extension direction of the guide rail 301, thereby limiting the amplitude of the first mounting plate 201 relative to the second mounting plate 202. On the one hand, the vibration reduction mechanism 300 can limit the amplitude of the first mounting plate 201, so that the tension of the winding rope during the movement is limited to prevent the winding rope from being damaged; on the other hand, the vibration intensity of the first mounting plate 201 can be reduced through the elastic buffering effect of the elastic member, thereby reducing the impact of the load on the human body and improving the walking comfort. The elastic member of the vibration reduction mechanism 300 is a constant force spring, and the guide rail 301 is sleeved with a second guide rail fixing member 303, and the second guide rail fixing member 303 is fixed on the first mounting plate 201. The constant force spring includes a first constant force spring 305 and a second constant force spring 306, and is respectively sleeved on the guide rails 301 on both sides of the second guide rail fixing member 303. In this way, when the first mounting plate 201 vibrates, the second guide rail fixing member 303 fixed on the first mounting plate 201 can be driven by the first mounting plate 201 to vibrate synchronously. Further, the vibration intensity of the first mounting plate 201 is reduced by the elastic buffering effect of the first constant force spring 305 and the second constant force spring 306, thereby reducing the impact of the weight on the human body and improving the walking comfort. Specifically, the two ends of the guide rail 301 are fixed to the second mounting plate 202 by the first guide rail fixing member 302 and the third guide rail fixing member 304, respectively. Specifically, the first guide rail fixing member 302 and the third guide rail fixing member 304 of each vibration reduction mechanism 300 are fixed on the second mounting plate 202 , and the second guide rail fixing member 303 of each vibration reduction mechanism 300 is fixed on the first mounting plate 201 .

[0140] For the convenience of calculation, we assume that under normal circumstances, the load on the first mounting plate is 5kg, and the spring of the adjustable mechanism is in a free height state. In this state, the gravity force on the shock absorbing mechanism is 5kg, that is, gravity = mass * gravity acceleration, that is, G = 5kg * 9.8m / s 2 The tunable spring in the tunable mechanism is at free length, it is not compressed or stretched, so the spring does not exert any force and does not generate any force. Therefore, the force analysis is as follows:

[0141] F1+5×g=F2 (5)

[0142] F1=k1×x1 (6)

[0143] F2=k2×x2 (7)

[0144] In equations (5) to (7), g: acceleration due to gravity, taken as 9.8 m / s 2 ,

[0145] F1, F2: The force of the first constant force spring and the second constant force spring (unit: N),

[0146] k1, k2: elastic coefficients of the first constant force spring and the second constant force spring (unit: N / m),

[0147] x1, x2: deformation of the first constant force spring and the second constant force spring (unit: m).

[0148] When the load is 5kg, the compression of the first constant force spring is 0, that is, no force is applied to the second rail fixing member. In this case, the spring force F2 = k2 × x2 = 24N. Considering that the power generation equipment requires a constant force spring to play a role in shock absorption and rebound, the elastic coefficient of the selected spring cannot be too large. Therefore, the elastic coefficient k of the spring selected in this embodiment is 1KN / m to 1.5KN / m. According to the formula Select the elastic coefficient, where k is the spring elastic coefficient (unit: N / m), G is the shear modulus of the spring material (unit: Pa), d is the spring wire diameter (unit: m), D is the average coil diameter of the spring, that is, the outer diameter of the spring (unit: m), and Na is the total number of spring coils, without unit.

[0149] This embodiment uses a spring steel spring with a wire diameter of 1.6 mm, an outer diameter of 15 mm, and a length of 150 mm, and its elastic coefficient k is 1.16 KN / m. According to k=1.16 KN / m, we can calculate that under a load of 5 kg, the compression amount of the second constant force spring is 18.8 mm, and the total length of the installation of a single set of shock absorbing mechanisms is about 310 mm.

[0150] The pulley assembly in the outdoor power generation equipment disclosed in this embodiment can amplify the stroke and damping, and can amplify the up and down movement stroke to the rotating generator by four times, thereby improving the power generation efficiency. By connecting with the pulley assembly in a winding manner, the linear motion of a large stroke is converted into a reciprocating motion of a small stroke. When the first mounting plate moves up and down linearly, the energy capture mechanism composed of the winding wheel, the transmission gear, the generator and other components will convert the mechanical energy of this part of the displacement difference into electrical energy; the vibration reduction mechanism in the outdoor power generation equipment disclosed in this embodiment can reduce the vibration force of the first mounting plate through the elastic buffering effect of the elastic member, thereby reducing the impact of the load on the human body and improving the walking comfort; the tunable mechanism in the outdoor power generation equipment disclosed in this embodiment can make the first mounting plate have a more regular vibration in the vertical direction relative to the second mounting plate and can maintain a relatively high amplitude, ensuring that the center of gravity of the first mounting plate can always be at an appropriate position height under different load conditions, thereby capturing more electrical energy; various materials in the outdoor power generation equipment disclosed in this embodiment are made of lighter materials, the thickness of the first mounting plate and the second mounting plate are very thin, and the use of a rotating generator also makes the structure of the power generation mechanism simpler, so that the outdoor power generation equipment itself is light in weight, which can reduce the burden on the human body during outdoor sports.

[0151] Embodiment 2

[0152] This embodiment is directed to the outdoor power generation method of the third aspect, and manufactures the above-mentioned outdoor power generation equipment into a shock-absorbing power generation backpack, which can be used in situations where power resources need to be supplemented during outdoor or field travel or camping. It solves the technical problems in the prior art that the power generation backpack has low power generation efficiency and complex structure, which easily leads to the heavy weight of the power generation backpack itself, thereby affecting the comfort of use.

[0153] like Figures 11 to 13 The present embodiment discloses a vibration-reducing power generation backpack 500, comprising a shoulder strap 501, a storage bag 502 and the outdoor power generation device described in the first embodiment, wherein the shoulder strap 501 is used to fix the vibration-reducing power generation backpack 500 on the back of the user, the storage bag 502 has a storage space, and the storage space is used to place items, the storage bag 502 is fixedly connected to a first mounting plate 201 on the side facing the shoulder strap 501, and the shoulder strap 501 is fixedly connected to a second mounting plate 202 on the side facing the storage bag 502; the power generation mechanism 100, the shock absorbing mechanism 300 and the tunable mechanism 400 are installed between the first mounting plate 201 and the second mounting plate 202.

[0154] As a preferred embodiment of the vibration-reducing power generation backpack 500, a waist fixing belt 503 is further provided on the shoulder strap 501 for fixing to the user's waist. The waist fixing belt 503 includes a buckle. When the buckle is opened, the waist fixing belt 503 can be separated into two parts, so that the waist fixing belt 503 can be conveniently fixed to the user's waist.

[0155] Setting a waist belt can transfer part of the weight of the backpack from the shoulders to the waist, reducing the burden on the shoulders. At the same time, it can make the backpack fit closely to the body, reducing the possibility of shaking and swaying, thereby reducing fatigue and discomfort. When the user needs to engage in high-intensity exercises such as rock climbing, hiking and other activities, the waist belt can provide additional support and stability.

[0156] Specifically, the vibration reduction power generation backpack disclosed in this embodiment is also provided with a power storage module, the power storage module is provided with a power storage interface, the power storage interface is provided with a power storage interface terminal, the power storage interface terminal is circuit-connected to the power output terminal of the generator through wires, the power storage module can collect and store the electric energy output by the generator, the power storage module is provided with an external power supply interface, the external power supply interface is provided with a power supply interface terminal, and can connect to an external device and supply power to the external device. The charging circuit and the external power supply circuit of the power storage module are both prior art and will not be described in detail here. Specifically, the power storage module has a shell, and the modules in the power storage module except the battery are on a circuit board, the battery and the circuit board are fixed in the shell, and the power storage interface and the external power supply interface are both provided on the shell wall.

[0157] The usage process of the shock-absorbing power-generating backpack disclosed in this embodiment is: put the items into the storage bag, carry the shock-absorbing power-generating backpack on the back, fix the waist strap to the user's waist, connect the power storage module and the power generation mechanism through wires, and start exercising (walking, running or jumping). Then, during exercise, the power generation mechanism starts to generate electricity and stores the generated electricity in the power storage module; when the external device needs to be charged, connect the external device to the external power supply interface of the power storage module, and the power range of the external power supply is 5~12w.

[0158] The working principle of this embodiment is to convert the relative displacement between the center of gravity of the backpack and the center of gravity of the human body into mechanical energy and then into electrical energy through the energy capture mechanism. Specifically, when there are items in the storage bag, the user's exercise is weight-bearing exercise, and the items in the storage bag are affected by the vibration of the user's body during exercise, and the center of gravity of the heavy objects will also produce vertical displacement, which will cause the first mounting plate to produce synchronous vertical vibration displacement;

[0159] Then, when the first mounting plate produces up and down vibration displacement, the second fixing part in the vibration reduction mechanism fixedly connected to the first mounting plate and the second mounting plate will move vertically up and down along the guide rail, and at the same time stretch or compress the constant force spring on the guide rail. Then, in the process of releasing or accumulating the elastic force, the power generation mechanism can generate electricity periodically. At the same time, due to the release or accumulation of the elastic force of the constant force spring, the vibration reduction function can also be realized, which can effectively reduce the impact of the weight on the human body and improve walking comfort.

[0160] Specifically, when the first mounting plate with a storage bag in the power generation mechanism moves vertically up and down, the first winding rope and the second winding rope are stretched alternately. Through the design of the double-groove winding wheel, when the first winding rope is stretched, it drives the winding wheel to rotate, and the rotation of the winding wheel drives the rotation of the transmission gear meshing with it, and then drives the motor shaft to rotate, thereby generating electricity. At the same time, the second winding rope will be wound into the winding groove of the winding wheel, keeping the two winding ropes in a taut state at all times to prevent them from derailing or entanglement with each other.

[0161] The shock absorbing mechanism 300 in the shock absorbing power generation backpack can elastically deform the first constant force spring 305 and the second constant force spring 306 in the shock absorbing mechanism 300 along the extension direction of the guide rail 301 when the user moves, thereby reducing the amplitude of the storage bag 502 relative to the shoulder strap 501.

[0162] In order to maintain the power of power generation at a high level, an adjustable mechanism is also provided. The reason for the design of the adjustable mechanism is that in the vibration-damping power generation backpack 500, the center of gravity of the storage bag 502 load is consistent with the center of gravity of the first mounting plate 201. However, when the weight of the backpack 500 increases, the first mounting plate 201 will move downward under the action of gravity, causing the center of gravity of the first mounting plate 201 and the storage bag 502 load to drop and gradually approach the center of gravity of the human body. Since the principle of the backpack is to convert the relative displacement between the center of gravity of the backpack and the center of gravity of the human body into mechanical energy and then into electrical energy through an energy capture mechanism. Then, if the center of gravity of the first mounting plate 201 with the storage bag 502 drops, the effective stroke of the energy capture mechanism will be reduced.

[0163] Therefore, the designed tunable mechanism 400 can, when the user moves, with the support of the limited elastic compression deformation of the tuning spring, limit the drop of the center of gravity of the first mounting plate with the storage bag so that its center of gravity can be maintained at an appropriate height. This ensures that the center of gravity of the first mounting plate is always at an appropriate height under different storage bag load conditions, thereby capturing more electrical energy.

[0164] The power generation mechanism used in the power generation backpack disclosed in this embodiment is a combination of a linear transmission and a gear group meshing mechanism. For the weight of the whole machine, the linear transmission method is adopted, the structure is simpler and lighter, and the weight can be effectively reduced, so the burden of the whole machine on the human body can be reduced. The linear transmission method can also realize the conversion of the linear motion of the backpack load into a rotary motion, which can improve the power generation efficiency. In this embodiment, the pulley assembly can amplify the stroke and damping, and can amplify the up and down movement of the backpack four times to the rotating generator, thereby improving the power generation efficiency. The vibration reduction mechanism in this embodiment is connected to the pulley assembly by winding, and the linear motion of the large stroke is converted into the reciprocating motion of the small stroke. When the first mounting plate moves up and down linearly, the energy capture mechanism composed of the winding wheel, the transmission gear, the generator and other components will convert the mechanical energy of this part of the displacement difference into electrical energy. The vibration reduction mechanism can reduce the vibration intensity of the first mounting plate through the elastic buffering effect of the elastic member, thereby reducing the impact of the load on the human body and improving the walking comfort. Various materials in this embodiment are made of lighter materials. The thickness of the first mounting plate and the second mounting plate is very thin. The use of a rotating generator also makes the structure of the power generation mechanism simpler, thereby making the vibration-damping power generation backpack itself light in weight and being able to reduce the burden on the human body during outdoor sports.
