Description

Technical Field

[0001] The utility model relates to the field of power generation, and particularly to a power generation device applied to a climbing machine. Background Art

[0002] In recent years, climbing machines have become very popular because they can effectively provide a full-body workout while challenging the muscles and cardiovascular system. A climbing machine usually has two handgrips and two pedals. The handgrips are used for holding with both hands, and the pedals are used for stepping on with both feet. During exercise, the two pedals move up and down in a fixed direction, and correspondingly, the two handgrips also move up and down in a parallel or the same direction. For example, when the left pedal moves down, the right pedal moves up, the left handgrip moves down, and the right handgrip moves up; when the left pedal moves up, the right pedal moves down, the left handgrip moves up, and the right handgrip moves down. In this way, by stepping up and down with both feet, training can be carried out.

[0003] Normally, the pedals and handgrips of a climbing machine move along a fixed direction that is inclined at a certain angle to the vertical direction. When a user is training normally, the pedals and handgrips will move back and forth along this direction, and their movement has a certain pattern: linear reciprocating displacement. If this movement can be utilized, converted into electrical energy, and then stored or used to supply power to terminal devices, energy can be saved and energy utilization efficiency can be improved.

[0035] The following embodiments are further explanations and supplements to the present utility model and do not constitute any limitation to the present utility model.

[0036] As Figures 1 to 5 shown, the power generation device of the present utility model includes a driving rod 10, a transmission mechanism 20 and a power generation component 30.

[0037] The driving rod 10 is used to connect with two pedals of the climbing machine to receive the movement of the climbing machine and generate electricity by using the movement of the climbing machine. The driving rod 10 includes a first driving rod 11 and a second driving rod 12 which are arranged in parallel at intervals. Among them, the first driving rod 11 is used to connect with the first pedal or the first grip of the climbing machine, and the second driving rod 12 is used to connect with the second pedal or the second grip of the climbing machine. When the user uses the climbing machine, the first pedal / first grip and the second pedal / second grip of the climbing frame move alternately up and down, which can drive the first driving rod 11 and the second driving rod 12 to move alternately up and down.

[0038] The transmission mechanism 20 is used to transmit the movement of the driving rod 10 to the power generation component 30 to drive the power generation component 30 to generate electricity. The transmission mechanism 20 is provided with an output rotating shaft 21. The transmission mechanism 20 is connected with the driving rod 10, and it can convert the linear movement of the driving rod 10 into the rotation of the output rotating shaft 21. When the first driving rod 11 and the second driving rod 12 move alternately up and down, the transmission mechanism 20 can convert this linear movement so that the output rotating shaft 21 rotates.

[0039] The power generation component 30 is used for induction power generation, and it includes a magnetic coil assembly 31 and a coil assembly 32. One of the magnetic coil assembly 31 and the coil assembly 32 is connected with the output rotating shaft 21 and can rotate synchronously with the output rotating shaft 21, and the other is fixedly arranged. In this way, when the output rotating shaft 21 rotates, the magnetic coil assembly 31 and the coil assembly 32 generate relative rotation and can generate induced current, thereby realizing power generation.

[0040] In some embodiments, the magnetic ring assembly 31 is connected to the output rotating shaft 21 and can rotate synchronously with the output rotating shaft 21, while the coil assembly 32 is fixedly arranged on the box body 40. When the output rotating shaft 21 rotates, the magnetic ring assembly 31 rotates.

[0041] In this embodiment, as Figure 2 shown, the coil assembly 32 is connected to the output rotating shaft 21 and can rotate synchronously with the output rotating shaft 21, while the magnetic ring assembly 31 is fixedly arranged on the box body 40. When the output rotating shaft 21 rotates, the coil assembly 32 rotates.

[0042] The coil assembly 32 can be a known coil assembly. In this embodiment, the coil assembly 32 is in a disc shape, sleeved on the output rotating shaft 21 and fixedly connected thereto, so as to rotate synchronously with the output rotating shaft 21.

[0043] The magnetic ring assembly 31 can be a known magnetic ring assembly. In this embodiment, the magnetic ring assembly 31 includes an annular magnet 311 and an end cover 312 for fixedly arranging the magnet. The magnet 311 can be a single magnet or a ring formed by splicing multiple magnets. The magnet 311 is fixedly arranged on the inner wall of the end cover 312 and is fixedly arranged on the box body 40 through the end cover 312.

[0044] The coil assembly 32 is arranged inside the magnetic ring assembly 31 and can rotate inside the magnetic ring assembly 31, so that an induced current can be generated on the coil assembly 32 through relative rotation, and then the induced current can be utilized.

[0045] Further, the transmission mechanism 20 includes a first fixing rod 22, a second fixing rod 23, a swing rod 24, a first connecting rod 25 and a second connecting rod 26.

[0046] One end of the first fixing rod 22 is fixedly connected to the first driving rod 11, and the other end is movably connected to the swing rod 24. Preferably, the first fixing rod 22 is movably connected to the end of the swing rod 24. The movable connection between the first fixing rod 22 and the swing rod 24 should enable the swing rod 24 to have a rotational degree of freedom in at least one direction, so as to meet the position changes of the first fixing rod 22 and the second fixing rod 23.

[0047] One end of the second fixing rod 23 is fixedly connected to the second driving rod 12, and the other end is movably connected to the swing rod 24. Preferably, the second fixing rod 23 is movably connected to the end of the swing rod 24. The movable connection between the second fixing rod 23 and the swing rod 24 should enable the swing rod 24 to have a rotational degree of freedom in at least one direction, so as to meet the position changes of the first fixing rod 22 and the second fixing rod 23.

[0048] The motion planes where the first fixed rod 22 and the second fixed rod 23 are located can be parallel to or coincide with the motion planes where the first driving rod 11 and the second driving rod 12 are located, or they can be non-parallel. When the directions of the first fixed rod 22 and the second fixed rod 23 relative to the first driving rod 11 and the second driving rod 12 are different, the motion trajectories of the swing rod 24 are different.

[0049] The first fixed rod 22 and the second fixed rod 23 can be straight rods or non-straight rods, and they can be set as needed.

[0050] The swing rod 24 is movably connected between the ends of the first fixed rod 22 and the second fixed rod 23. It can move in a fixed plane or in a spatial range. The angles between the swing rod 24 and the first fixed rod 22 and the second fixed rod 23 will change with the movement.

[0051] One end of the first connecting rod 25 is rotatably connected to the first fixed rod 22 or the swing rod 24, and the other end is rotatably connected to one end of the second connecting rod 26. The other end of the second connecting rod 26 is fixedly connected or integrally formed with the output rotating shaft 21. The first connecting rod 25 and the second connecting rod 26 are used to transmit the motion to the output rotating shaft 21 so that the output rotating shaft 21 can rotate.

[0052] Preferably, one end of the first connecting rod 25 is rotatably connected to the first fixed rod 22.

[0053] The rotation centers of the first connecting rod 25 and the first fixed rod 22 or the swing rod 24 are parallel and spaced from the axial direction of the output rotating shaft 21. The rotation centers of the first connecting rod 25 and the second connecting rod 26 are parallel and spaced from the axial direction of the output rotating shaft 21.

[0054] To avoid rotational interference, the first connecting rod 25 and the output rotating shaft 21 should be arranged on both sides of the second connecting rod 26.

[0055] The arrangement between the second connecting rod 26 and the output rotating shaft 21 should enable them to rotate synchronously. For example, the second connecting rod 26 and the output rotating shaft 21 are integrally formed, and the second connecting rod 26 extends radially outside the output rotating shaft 21. Another example is that a groove is provided on the output rotating shaft 21 along the radial direction, and one end of the second connecting rod 26 is fixedly embedded in the groove to achieve circumferential limit connection, and the two can rotate synchronously.

[0056] When the first driving rod 11 and the second driving rod 12 move alternately up and down (it should be noted that this up and down does not refer to the up and down movement in the vertical direction, but the up and down movement in the direction of the pedal movement of the climbing machine, which is usually inclined to the vertical direction), the first fixed rod 22 and the second fixed rod 23 move alternately up and down with the first driving rod 11 and the second driving rod 12, so as to drive the output rotating shaft 21 to rotate through the first connecting rod 25 and the second connecting rod 26.

[0057] To facilitate the setting of the driving rod 10, the transmission mechanism 20 and the power generation component 30, the power generation component 30 further includes a box body 40. A first through hole 41 and a second through hole 42 are provided on the box body 40.

[0058] The transmission mechanism 20 and the power generation component 30 are arranged inside the box body 40. The first driving rod 11 extends out of the box body 40 through the first through hole 41 from the inside of the box body 40. The second driving rod 12 extends out of the box body 40 through the second through hole 42 from the inside of the box body 40. The first fixed rod 22, the second fixed rod 23, the swing rod 24, the first connecting rod 25, and the second connecting rod 26 are located inside the box body 40 and do not interfere with the box body 40; the output rotating shaft 21 is rotatably arranged on the box body 40, and one of the magnetic ring assembly 31 or the coil assembly 32 is coaxially fixed to the output rotating shaft 21 and can rotate synchronously, and the other is fixed on the box body 40.

[0059] During use, the box body 40 is fixed at a suitable position of the climbing machine, and then the first driving rod 11 and the second driving rod 12 are respectively connected to the first pedal / first grip and the second pedal / second grip, and then it can be used for power generation during exercise.

[0060] To facilitate the adjustment of the distance between the first driving rod 11 and the second driving rod 12 to adapt to different models of climbing machines, the first through hole 41 and the second through hole 42 are strip-shaped holes, and the extending direction of the strip-shaped holes is parallel to the connection line direction between the first driving rod 11 and the second driving rod 12.

[0061] Furthermore, the power generation device may further include a first connecting plate 51 and a second connecting plate 52. The first connecting plate 51 is arranged at the end of the first driving rod 11, and the second connecting plate 52 is arranged at the end of the second driving rod 12. It is more convenient to detachably connect to the first pedal / first grip and the second pedal / second grip through the first connecting plate 51 and the second connecting plate 52. For example, it can be connected to the first pedal and the second pedal by tying.

[0062] Furthermore, the connection between the first driving rod 11 and the first connecting plate 51 and the connection between the second driving rod 12 and the second connecting plate 52 are movable connections.

[0063] In some embodiments, the first driving rod 11 and the first connecting plate 51 are rotatably connected, and the first driving rod 11 can rotate relative to the first connecting plate 51; similarly, the second driving rod 12 and the second connecting plate 52 are rotatably connected, and the second driving rod 12 can rotate relative to the second connecting plate 52.

[0064] In some embodiments, the first driving rod 11 and the first connecting plate 51 are slidably connected, and the first driving rod 11 can slide relative to the first connecting plate 51 along a preset direction; similarly, the second driving rod 12 and the second connecting plate 52 are slidably connected, and the second driving rod 12 can slide relative to the second connecting plate 52 along a preset direction.

[0065] The following is a specific introduction with different embodiments:

[0066] Embodiment 1

[0067] As shown in Figure 3 In this embodiment, the first fixing rod 22 and the second fixing rod 23 are straight rods, which are distributed on both sides of the first driving rod 11 and the second driving rod 12, and are inclined at an acute angle with the first driving rod 11 and the second driving rod 12.

[0068] Preferably, the angle between the first driving rod 11 and the first fixing rod 22 is the same as the angle between the second driving rod 12 and the second fixing rod 23.

[0069] The movement plane where the first fixing rod 22 and the second fixing rod 23 are located is parallel to or coincides with the movement plane where the first driving rod 11 and the second driving rod 12 are located. Similarly, the movement plane where the swing rod 24 is located is also parallel to or coincides with the movement plane where the first fixing rod 22 and the second fixing rod 23 are located.

[0070] A rotational connection is formed between the middle part of the swing rod 24 and the box body 40. Specifically, a support shaft 27 is provided on the box body 40, and the swing rod 24 is rotatably connected to the support shaft 27.

[0071] Of course, in other embodiments, the middle part of the swing rod 24 can also be freely arranged without being rotatably connected to the support shaft 27.

[0072] As shown in Figure 5As shown in the figure, to meet the movement requirements of the first driving rod 11 and the second driving rod 12, sliding grooves 53 are respectively provided on the first connecting plate 51 and the second connecting plate 52, and fitting portions 13 cooperating with the sliding grooves 53 are provided at the ends of the first driving rod 11 and the second driving rod 12. The extending direction of the sliding groove 53 is the same as that of the first through hole 41 and the second through hole 42. The fitting portion 13 is limitedly arranged in the sliding groove 53. The fitting portion 13 can slide in the sliding groove 53, but cannot escape from the sliding groove 53. In this way, the first driving rod 11 can slide relative to the first connecting plate 51, and the second driving rod 12 can slide relative to the second connecting plate 52, so as to meet the movement trajectory requirements of the first driving rod 11 and the second driving rod 12.

[0073] During use, the first connecting plate 51 is connected to the first pedal / first grip, the second connecting plate 52 is connected to the second pedal / second grip, and the box body 40 is fixedly arranged at a suitable position of the climbing machine.

[0074] When the user uses the climbing machine, the first pedal and the second pedal move up and down. Through the driving rod 10 and the transmission mechanism 20, the magnetic ring assembly 31 or the coil assembly 32 in the power generation assembly 30 can be driven to rotate, so that the magnetic ring assembly 31 and the coil assembly 32 rotate relative to each other to generate electricity.

[0075] Embodiment 2

[0076] As Figure 1 shown, in this embodiment, the first fixing rod 22 and the second fixing rod 23 are bent, and are distributed on both sides of the first driving rod 11 and the second driving rod 12, and the bottoms of the first fixing rod 22 and the second fixing rod 23 deviate from the central axes of the first driving rod 11 and the second driving rod 12. In other words, the bottoms of the first fixing rod 22 and the second fixing rod 23 are not collinear with the first driving rod 11 and the second driving rod 12. In this way, the position changes during movement can be adapted by the rotation of the first driving rod 11 and the second driving rod 12.

[0077] The swing rod 24 is only connected to the first fixing rod 22 and the second fixing rod 23 at both ends, and no connection is provided in the middle of the swing rod 24. The swing rod 24 can swing within the spatial range.

[0078] As Figure 4As shown in the figure, to meet the movement requirements of the first driving rod 11 and the second driving rod 12, bearings 54 are provided on the first connecting plate 51 and the second connecting plate 52. The end portions of the first driving rod 11 and the second driving rod 12 are respectively installed in the bearings 54, so that the first driving rod 11 forms a rotational connection with the first connecting plate 51, and the second driving rod 12 forms a rotational connection with the second connecting plate 52. In this way, the first driving rod 11 can rotate relative to the first connecting plate 51, and the second driving rod 12 can rotate relative to the second connecting plate 52.

[0079] To limit the axial displacement between the first driving rod 11 and the first connecting plate 51, bolts 60 can be provided between the first driving rod 11 and the first connecting plate 51, and between the second driving rod 12 and the second connecting plate 52: Threaded holes extending axially are provided at the end portions of the first driving rod 11 and the second driving rod 12. The bolt 60 passes through the first connecting plate 51 and is threadedly connected to the threaded hole of the first driving rod 11, and the head 61 of the bolt 60 is located outside the first connecting plate 51 to prevent detachment; similarly, another bolt 60 passes through the second connecting plate 52 and is threadedly connected to the threaded hole of the second driving rod 12, and the head 61 of the bolt 60 is located outside the second connecting plate 52 to prevent detachment. In this way, a rotational connection is formed between the first driving rod 11 and the first connecting plate 51 and they will not separate; a rotational connection is formed between the second driving rod 12 and the second connecting plate 52 and they will not separate, thus meeting the movement requirements of the first driving rod 11 and the second driving rod 12.

[0080] During use, the first connecting plate 51 is connected to the first pedal / first grip, the second connecting plate 52 is connected to the second pedal / second grip, and the box body 40 is fixedly installed at a suitable position of the climbing machine.

[0081] When the user uses the climbing machine, the first pedal and the second pedal move up and down. Through the driving rod 10 and the transmission mechanism 20, the magnetic ring assembly 31 or the coil assembly 32 in the power generation assembly 30 can be driven to rotate, so that the magnetic ring assembly 31 and the coil assembly 32 rotate relative to each other to generate electricity.

[0082] Embodiment 3

[0083] As Figure 1 shown, the first connecting plate 51 and the second connecting plate 52 of this embodiment are in plate shape, and are provided with a plurality of grid holes, which can facilitate the user to connect the first connecting plate 51 with the first pedal / first grip, and the second connecting plate 52 with the second pedal / second grip together using straps, cable ties, etc.

[0084] The lengths of the first fixing rod 22, the second fixing rod 23, the swing rod 24, the first connecting rod 25, and the second connecting rod 26 of the present utility model, as well as the distance between the first driving rod 11 and the second driving rod 12, can be set according to the actual situation. Preferably, they should meet the following conditions: when the first pedal and the second pedal move up and down, the second connecting rod 26 can drive the output rotating shaft 21 to rotate 360°. In this way, it can be ensured that the relative rotation of the magnetic ring assembly 31 and the coil assembly 32 is in one direction, so as to ensure that the direction of the induced current is consistent and more conducive to application.

[0085] Of course, if the second connecting rod 26 cannot drive the output rotating shaft 21 to rotate 360° when the first pedal and the second pedal move up and down, but can only reciprocate within an angle range less than 360°, the directions of the induced currents generated when the magnetic ring assembly 31 and the coil assembly 32 rotate relative to each other will be inconsistent. At this time, a rectifying unit can be set to rectify the induced current, and the output current direction can also be made consistent, thus facilitating practical application.

[0086] To facilitate the utilization of the generated induced current, in some embodiments, a rechargeable battery can be provided in the box body 40, and the generated induced current is transmitted to the rechargeable battery for storage. In this way, power can be taken for use when needed.

[0087] Of course, how to apply the induced current generated by the power generation assembly 30 can be set according to needs, and it is not limited to being stored through a rechargeable battery. It can also be directly transmitted to an electrical load.

[0088] Although the present utility model has been disclosed through the above embodiments, the scope of the present utility model is not limited thereto. Without departing from the concept of the present utility model, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
