[0002] When trampolines, swings and other equipment are in motion, the center point of the moving parts will produce displacement changes, such as up and down reciprocating displacement, left and right reciprocating swing, etc. For such equipment whose center point will undergo reciprocating displacement changes, if the mechanical energy of the displacement movement can be utilized, converted into electrical energy, and then stored or powered to terminal equipment, it can save energy and improve energy utilization. Utility Model Content

[0003] The utility model aims to solve the above problems and provides a displacement power generation device which can generate electricity by utilizing reciprocating displacement changes.

[0004] In order to solve the above problems, the utility model provides a displacement power generation device, which is characterized by comprising:

[0005] Fixed seat;

[0006] A take-up belt, which can be pulled out from the fixing seat and automatically taken up;

[0007] A winding mechanism is arranged in the fixed seat, and is used to drive the winding belt to automatically wind up, and can rotate along with the movement of the winding belt;

[0008] A power generation assembly is disposed in the fixing seat and connected to the winding mechanism.

[0009] At least one of the fixed seat and the winding belt is used to be fixed on a moving part that will produce reciprocating displacement changes. When the moving part performs reciprocating displacement movement, at least during the process of increasing displacement of the moving part, the winding belt can be stretched to drive the winding mechanism to rotate along the first direction so that the power generation component can generate electricity by induction.

[0010] Furthermore, when the moving part performs a reciprocating displacement motion, during the process of reducing the displacement of the moving part, the winding mechanism drives the winding belt to automatically wind up along a second direction opposite to the first direction.

[0011] Furthermore, the power generation component includes a coaxially arranged magnetic circle component and a coil component, and one of the magnetic circle component and the coil component are linked with the winding mechanism. When the winding mechanism rotates along a first direction, the magnetic circle component and one of the coil components are linked to cause the coil component and the magnetic circle component to rotate relative to each other, thereby generating an induced current on the coil component.

[0012] Furthermore, it also includes a reversal compensation mechanism, which is arranged between the winding mechanism and the power generation component and can be used to absorb the rotation of the winding mechanism. When the winding mechanism rotates along the second direction, the reversal compensation mechanism absorbs the rotation of the winding mechanism, and one of the coil assembly and the magnetic ring assembly that is linked to the winding mechanism keeps rotating under the action of inertia to generate an induced current on the coil assembly.

[0013] Furthermore, the winding mechanism comprises:

[0014] A first central axis, fixedly or rotatably disposed in the fixing seat;

[0016] A turbine spring, arranged in the rotating disk, for driving the take-up belt to automatically rewind;

[0017] The first gear is sleeved on the first central shaft and is fixedly connected with the rotating disk so as to be able to rotate synchronously.

[0018] Furthermore, the reverse compensation mechanism comprises:

[0019] A second central axis, fixedly or rotatably disposed in the fixing seat and spaced parallel to the first central axis;

[0022] A transmission part, fixedly connected to the second gear and capable of synchronous rotation;

[0023] A pawl is rotatably disposed on the transmission part, and one end of the pawl can cooperate with the inner ratchet to drive the inner ratchet wheel to rotate in one direction.

[0024] Furthermore, the magnetic ring assembly is sleeved on the second central axis and fixedly connected to the inner ratchet.

[0025] Furthermore, the coil assembly is sleeved on the second central axis and is stationary relative to the fixing seat.

[0026] The beneficial contribution of the utility model is that it effectively solves the above-mentioned problems. At least one of the fixed seat and the winding belt of the displacement power generation device of the utility model can be fixed on the moving part that produces reciprocating displacement changes, thereby driving the internal winding mechanism to rotate by sensing the displacement changes, and then linking the magnetic circle component and the coil component in the power generation component to produce relative rotation to generate electricity. The displacement power generation device of the utility model can utilize the reciprocating displacement changes generated during the use of various equipment to generate electricity, and the induced current generated by the power generation can be stored or supplied to the terminal equipment.

DETAILED DESCRIPTION

[0034] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0035] like Figure 1 to Figure 6 As shown, the displacement power generation device of the present invention includes a fixing seat 10 , a winding belt 20 , a winding mechanism 30 and a power generation assembly 40 .

[0036] The fixed seat 10 is used to carry the take-up belt 20, the winding mechanism 30 and the power generation component 40. The shape and appearance of the fixed seat 10 are not limited. In this embodiment, it is in the shape of a round box, and its interior is hollow and can be used to install the take-up belt 20, the winding mechanism 30 and the power generation component 40. The take-up belt 20 is arranged in the fixed seat 10, and it can be pulled out from the fixed seat 10 and can be automatically wound up. The winding mechanism 30 is arranged in the fixed seat 10, and it is used to drive the take-up belt 20 to be automatically wound up. In addition, the winding mechanism 30 can rotate with the movement of the take-up belt 20. When the take-up belt 20 is pulled outward, the winding mechanism 30 rotates in a first direction. When the take-up belt 20 is wound up, the winding mechanism 30 rotates in a second direction opposite to the first direction. The power generation component 40 is arranged in the fixed seat 10 and is directly or indirectly connected to the winding mechanism 30. The power generation component 40 is used for induction power generation. When the winding mechanism 30 is rotated by the movement of the winding belt 20, the power generation component 40 can convert the rotation into electrical energy.

[0037] At least one of the fixed seat 10 and the take-up belt 20 is used to be fixed on the moving part that can produce reciprocating displacement changes. Of course, the fixed seat 10 and the take-up belt 20 can also be fixed on the moving part that can produce reciprocating displacement changes. Since at least one of the fixed seat 10 and the take-up belt 20 is fixed on the moving part, when the moving part performs displacement movement, the take-up belt 20 can move relative to the fixed seat 10 and be stretched or contracted.

[0038] The moving part generally refers to a device that can produce reciprocating displacement changes, such as a trampoline. When someone jumps on the trampoline, the bed cloth of the trampoline will produce up and down reciprocating displacement changes. When in use, the fixed seat 10 and the take-up belt 20 can be fixed at opposite ends of the trampoline and pass through the bed cloth. In this way, when someone jumps on the trampoline, the take-up belt 20 can be stretched or contracted due to the up and down displacement changes of the bed cloth, and the displacement change of the moving part can be sensed. For another example, the moving part can be a swinging device, the fixed seat 10 can be fixed on the support frame of the swinging device, and the take-up belt 20 can be fixed on the swinging device of the swinging device. When the swinging device swings left and right, the take-up belt 20 can be stretched or contracted accordingly, and the displacement change of the moving part can be sensed.

[0039] Relative to the starting position (i.e. the original center point), the reciprocating displacement movement of the moving part can be decomposed into two stages: the displacement increase stage and the displacement reduction stage. Among them, the displacement increase stage is the displacement activity starting from the starting position. The displacement reduction stage is the reset to the starting position.

[0040] When the moving part performs reciprocating displacement motion, the winding belt 20 can be stretched at least during the process of increasing displacement of the moving part. When the winding belt 20 is stretched, it can drive the winding mechanism 30 to rotate along the first direction, so that the power generation component 40 can generate electricity by induction and convert the rotational mechanical energy into electrical energy.

[0041] Furthermore, the power generation component 40 includes a coaxially arranged magnetic coil component 41 and a coil component 42. One of the magnetic coil component 41 and the coil component 42 is arranged in linkage with the winding mechanism 30, and the other is arranged stationary. In this way, when the winding mechanism 30 rotates in the first direction, the coil component 42 and the magnetic coil component 41 can rotate relative to each other to generate an induced current on the coil component 42, thereby realizing the power generation process of converting mechanical energy into electrical energy.

[0042] In this embodiment, the magnetic coil assembly 41 is linked with the winding mechanism 30. When the winding mechanism 30 rotates along the first direction, the magnetic coil assembly 41 rotates, and the coil assembly 42 does not rotate.

[0043] In some other embodiments, the coil assembly 42 is linked to the winding mechanism 30. When the winding mechanism 30 rotates along the first direction, the coil assembly 42 rotates, and the magnetic coil assembly 41 does not rotate.

[0044] Furthermore, during the displacement reduction process of the moving part, the take-up belt 20 is no longer pulled outward, and the take-up mechanism 30 can drive the take-up belt 20 to automatically rewind along the second direction. At this time, the take-up mechanism 30 itself also rotates in the second direction.

[0045] Furthermore, when the winding mechanism 30 rotates in the second direction, the rotation of the winding mechanism 30 does not link the power generation component 40. In order to ensure that the rotation of the winding mechanism 30 does not link the power generation component 40 during this process, the displacement power generation device of the utility model is further provided with a reverse compensation mechanism 50.

[0046] The reverse offset mechanism 50 is arranged between the winding mechanism 30 and the power generation component 40, and is used to absorb the rotation of the winding mechanism 30. When the winding mechanism 30 rotates in the second direction, the reverse offset mechanism 50 absorbs the rotation of the winding mechanism 30, so that the winding mechanism 30 will not be linked to the magnetic circle component 41 or the coil component 42. At this time, the coil component 42 and the magnetic circle component 41 that were previously linked to the winding mechanism 30 will continue to rotate under the action of inertia, so that an induced current is generated on the coil component 42. When the inertial action ends and there is no displacement change in the moving part, the coil component 42 and the magnetic circle component 41 are both in a stationary state. When the inertial action ends, if the displacement of the moving part increases, the winding belt 20 will drive the winding mechanism 30, and the winding mechanism 30 will be linked to the magnetic circle component 41 or the coil component 42 to rotate one of them, thereby generating an induced current on the line weight component.

[0047] Furthermore, the winding mechanism 30 includes a first central shaft 31 , a rotating disk 32 , a turbine spring 33 , and a first gear 34 .

[0048] The first central axis 31 is disposed in the fixing seat 10, and can be fixedly disposed or rotatably disposed in the fixing seat 10. When the first central axis 31 is rotatably disposed in the fixing seat 10, the first central axis 31 rotates around a fixed axis.

[0049] Preferably, both ends of the first central axis 31 are fixedly connected to the fixing seat 10 respectively.

[0050] The rotating disk 32 is sleeved on the first central shaft 31 and can rotate relative to the fixing seat 10. The winding belt 20 is arranged on the rotating disk 32, and the stretching of the winding belt 20 can drive the rotating disk 32 to rotate around the central axis of the first central shaft 31.

[0051] The turbine spring 33 is disposed in the rotating disk 32 and is used to drive the take-up belt 20 to automatically rewind.

[0052] Furthermore, in order to facilitate the arrangement of the reel 20 and the turbine spring 33, the rotating disk 32 includes a flat plate portion 321 and a sleeve portion 322. The sleeve portion 322 is vertically arranged on the flat plate portion 321. The reel 20 is arranged on the outside of the sleeve portion 322, and the turbine spring 33 is arranged inside the sleeve portion 322. The connection between the reel 20, the turbine spring 33 and the sleeve portion 322 can refer to the known technology, which is more common in the tape measure structure, and should be able to meet the following conditions: when the reel 20 is stretched, it can drive the rotating disk 32 to rotate in the first direction and make the turbine spring 33 elastically deform; when the reel 20 loses the external tension, the turbine spring 33 resets and drives the reel 20 and the rotating disk 32 to rotate in the opposite direction in the second direction and automatically reel.

[0053] The first gear 34 is sleeved on the first central shaft 31 and fixedly connected to the rotating disk 32 so as to rotate synchronously. The first gear 34 is provided with external teeth for driving the reverse rotation compensation mechanism 50 .

[0054] Furthermore, the reverse rotation canceling mechanism 50 may include a second central shaft 51 , a second gear 52 , an inner ratchet 53 , a transmission part 54 and a pawl 55 .

[0055] The second central axis 51 is disposed in the fixing seat 10 and is parallel and spaced from the first central axis 31. The second central axis 51 can be fixedly disposed or rotatably disposed in the fixing seat 10. Preferably, both ends of the second central axis 51 are fixedly connected to the fixing seat 10.

[0056] The second gear 52 is sleeved on the second central shaft 51 and meshes with the first gear 34 .

[0057] The inner ratchet 53 is sleeved on the second central shaft 51 and is provided with inner ratchet teeth 531 .

[0058] The transmission part 54 is fixedly connected to the second gear 52 and can rotate synchronously. In this embodiment, the transmission part 54 is sleeved on the second central shaft 51 and fixed to the end of the second gear 52 away from the take-up belt 20. The shape of the transmission part 54 is not limited, and it should be able to rotate in the inner ratchet 53 with the second gear 52 without interfering with the rotation of the inner ratchet 53.

[0059] The pawl 55 is rotatably disposed on the transmission part 54, and can rotate around a fixed axis parallel to the second central axis 51. One end of the pawl 55 cooperates with the inner ratchet 531, and can drive the inner ratchet 53 to rotate in one direction. The connection structure between the pawl 55 and the transmission part 54, and the cooperation between the pawl 55 and the inner ratchet 531, can refer to the known technology, and the pawl 55 can drive the inner ratchet 53 to rotate in one direction, and this embodiment does not specifically limit them.

[0060] When the take-up belt 20 is pulled outward, the rotating disk 32 and the first gear 34 rotate in the first direction, and the turbine spring 33 elastically deforms; the second gear 52, the transmission part 54, and the pawl 55 rotate in the second direction, and the pawl 55 drives the inner ratchet 53 to rotate in the second direction.

[0061] When the take-up belt 20 loses the external tension, the turbine spring 33 is reset to drive the rotating disk 32 and the first gear 34 to rotate in the second direction opposite to the first direction, and the second gear 52, the transmission part 54, and the ratchet 55 rotate in the first direction. At this time, the ratchet 55 rotates freely in the inner ratchet 53 and cannot drive the inner ratchet 53 to rotate. At this time, the inner ratchet 53 can rotate in the second direction for a while under the action of inertia.

[0062] Furthermore, the magnetic circle assembly 41 is sleeved on the second central shaft 51 and fixedly connected to the inner ratchet 53. In this embodiment, the magnetic circle assembly 41 is fixedly arranged at one end of the inner ratchet 53 away from the second gear 52.

[0063] Furthermore, the coil assembly 42 is sleeved on the second central axis 51 and is stationary relative to the fixing seat 10. The coil assembly 42 and the second central axis 51 may be fixedly connected or rotatably connected, and the coil assembly 42 can be stationary relative to the fixing seat 10.

[0064] The structures of the coil assembly 42 and the magnetic coil assembly 41 may refer to the known technology. In this embodiment, the wire magnetic coil assembly 41 is provided with a magnet frame 411 and an annular magnet 412. The magnet frame 411 is sleeved on the second central shaft 51 and fixedly connected to the inner ratchet 53. The annular magnet 412 is fixedly arranged on the circumferential inner wall of the magnet frame 411. The coil assembly 42 is disc-shaped and is located in the magnet frame 411, and is spaced a certain distance from the annular magnet 412.

[0065] Thus, the displacement power generation device of this embodiment is formed. When the take-up belt 20 is stretched outward due to the increase in the displacement of the moving part, the take-up mechanism 30 rotates in the first direction, and the reverse compensation mechanism 50 rotates in the second direction, thereby driving the magnetic coil assembly 41 to rotate in the second direction through the inner ratchet 53, so that the magnetic coil assembly 41 and the coil assembly 42 produce relative rotation and generate an induced current on the coil assembly 42. When the displacement of the moving part decreases, the take-up belt 20 is automatically reeled under the action of the take-up mechanism 30. At this time, the take-up mechanism 30 rotates in the second direction, the second gear 52, the transmission part 54, and the ratchet 55 in the reverse compensation mechanism 50 rotate in the first direction, and the inner ratchet 53 continues to rotate in the second direction under the action of inertia, thereby driving the magnetic coil assembly 41 to rotate in the second direction and generating an induced current on the coil assembly 42.

[0066] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced by similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
