Technical Field

[0001] The utility model belongs to the technical field of pressure power generation, and relates to a footstep pressure power generation device, in particular to a device which can generate electric energy by utilizing the pressure applied to a pressure-bearing bottom plate when a person walks. Background Art

[0002] With the continuous development of science and technology and the enhancement of environmental protection awareness, people's demand for renewable energy is increasing. The technology of using the pressure of people walking to generate electricity has also attracted widespread attention. At present, there are few similar power generation devices in China. There are some similar power generation devices abroad, but they all have problems such as low efficiency, poor safety, and instability.

[0003] In the field of renewable energy, electric motors are often needed to generate electricity. However, some applications require a higher motor speed to improve the motor's power generation efficiency and output power, but there are certain technical limitations and room for development. Utility Model Content

[0004] In view of this, in order to solve the problems raised in the above background technology, the utility model increases the rotation speed and power generation efficiency of the motor through a mechanical structure, and provides a footstep pressure power generation device, which can more effectively and reliably increase the power generation efficiency of the motor to meet the demand for high-efficiency energy in specific application scenarios.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A footstep pressure power generation device comprises a plurality of pressure-bearing base plates and power generation devices which are all arranged below the ends of the pressure-bearing base plates and used in conjunction with the pressure-bearing base plates; the power generation device comprises a pressure cover fixedly connected to the ends of the pressure-bearing base plates, a spur rack arranged below the pressure cover, a gear meshing with the spur rack, a gear shaft fixedly connected to the gear, a second bevel gear fixedly connected to the gear shaft, and a first bevel gear meshing with the second bevel gear, a ratchet shaft is fixedly connected below the first bevel gear, a ratchet disk is provided at the lower end of the ratchet shaft, ratchet teeth are coaxially connected to the first bevel gear and rotatably connected to the ratchet shaft, the ratchet teeth are assembled and connected to the ratchet disk, a motor is installed below the ratchet disk, and a spring mounted on the spur rack is fixed below the pressure cover.

[0007] The beneficial effect of this basic solution is that when the pressure-bearing bottom plate moves downward, one corner of it transmits pressure to the gland, driving the gland to descend and compressing the spring. The gland descends and drives the spur rack downward, which drives the gear to rotate. This in turn drives the gear shaft, the second bevel gear to rotate, the second bevel gear meshes with the first bevel gear, the first bevel gear drives the ratchet shaft to rotate clockwise, the ratchet shaft drives the ratchet teeth to rotate, and in the case of clockwise rotation, the ratchet teeth will get stuck in the ratchet disk, and push the ratchet disk to rotate, which in turn drives the motor to rotate, cutting the magnetic flux lines to generate electricity;

[0008] When the pressure on the pressure bottom plate disappears, the spring rebounds, pushing the gland up, and the gland rises, driving the spur rack upward, and the spur rack drives the gear to rotate. Then it drives the gear shaft, the second bevel gear rotates, the first bevel gear drives the ratchet shaft to rotate counterclockwise, and the ratchet shaft drives the ratchet teeth to rotate. In the case of counterclockwise rotation, the ratchet teeth will not get stuck in the ratchet disk, but will shrink and rotate, and will not drive the ratchet disk to rotate, so the motor will not rotate. The unidirectional rotation of the motor facilitates the collection and storage of electrical energy, reduces resistance, and relies on the elastic potential energy of the spring to rebound, lift the gland to the initial position, and drive the pressure bottom plate back to the initial position to complete a power generation.

[0009] Furthermore, a groove having the same shape as the ratchet teeth is provided on the upper surface of the ratchet disc. Beneficial effect: the groove is used for assembling the ratchet teeth.

[0010] Furthermore, each end of the pressure-bearing bottom plate is fixed with a connecting piece, which is placed on a gland in the power generation device, and a top cover is arranged on the gland, and a groove is formed between the top cover and the gland. Beneficial effect: The connecting piece is fixed to the gland through the top cover.

[0011] Furthermore, the power generating device comprises a supporting shell and an auxiliary shell, and the bottoms of the supporting shell and the auxiliary shell are fixed with a same bottom plate.

[0012] Furthermore, groove-shaped limiting holes for connecting and limiting the spur racks are provided on the lower surface of the top cover and the upper surface of the supporting shell.

[0013] Furthermore, a rubber protective sleeve is installed on the lower side of the gland, a top plate is fixed on the upper side of the bottom end of the rubber protective sleeve, an annular groove is opened on the upper surface of the top plate, and a rubber ring is fixed on the upper side of the annular groove. Beneficial effect: the rubber protective sleeve plays a role in dust prevention and spring protection, and the rubber ring plays a role in buffer protection.

[0014] Furthermore, the top plate is fixedly connected to the supporting shell, the spur rack runs through the top plate, and the inner cavity of the supporting shell is provided with a limiting groove adapted to the spur rack. Beneficial effect: Through the limiting groove, the spur rack can achieve up and down displacement.

[0015] Furthermore, the motor adopts an outer rotor structure, the motor flange is fixedly connected to the motor fixed housing, and the side of the ratchet disk close to the motor is connected to the motor through a coupling.

[0016] Furthermore, the side of the gear shaft away from the second bevel gear is rotatably connected to the first bearing and is connected to the supporting shell, and the side of the gear shaft close to the second bevel gear is rotatably connected to the second bearing.

[0017] Furthermore, a support frame supporting the gear shaft is arranged below the gear shaft, and the support frame is fixedly connected to the base plate.

[0018] Furthermore, the gear shaft is placed on the support frame through a second bearing, and the upper end of the ratchet shaft is installed inside the auxiliary outer cover through a third bearing.

[0019] Furthermore, the pressure-bearing bottom plate is in the shape of an equilateral triangle, and the three ends are fixed with connecting pieces, and the other side of the connecting piece is fixedly connected to the groove formed by the pressure cover and the top cover.

[0020] The beneficial effects of the utility model are:

[0021] 1. The footstep pressure electricity generating device disclosed in the utility model drives the ratchet teeth connected thereto to rotate coaxially through the ratchet shaft. When the upper side of the device is subjected to pressure, that is, when the pressure cover is pressed down, the spring is compressed, the ratchet shaft rotates forward, and the ratchet teeth drive the ratchet disk to rotate forward, thereby causing the outer rotor of the motor to rotate forward. When the pressure disappears, the spring returns to its original length, the ratchet shaft reverses, and the ratchet disk has a special limiting structure, and the two ratchet teeth shrink toward the center of the circle and no longer drive the ratchet disk to rotate, thereby achieving the effect of rectifying unstable alternating current, which is convenient for the collection and storage of electrical energy.

[0022] 2. The footstep pressure power generation device disclosed in the utility model drives three power generation devices to generate electricity at the same time through a pressure-bearing base plate, and evenly distributes the pressure on the upper surface of the pressure-bearing base plate to the pressure covers of the three power generation devices, and then drives the transmission mechanism to rotate the outer rotor of the generator motor through the downward pressure of the pressure cover, thereby generating a more stable voltage, improving the conversion efficiency and achieving the expected effect.

[0023] 3. The footstep pressure electricity generating device disclosed in the utility model can be suitable for venues with large traffic flow. The supporting frame and the motor fix the outer shell, and the spur rack and the gear, the second bevel gear and the first bevel gear are mutually engaged, which is convenient for loading and unloading and regular maintenance, thereby reducing maintenance costs. There are bearings at both ends of the gear shaft and the ratchet shaft, and they are effectively limited by the supporting outer shell and the supporting frame, making the transmission more reliable. At the same time, the supporting outer shell and the auxiliary outer shell are fixedly connected, which improves the safety performance of the device.

[0044] Embodiment 1

[0045] Reference Figure 5 The pressure-bearing bottom plates 25 are all in the shape of equilateral triangles, and the three ends are fixed with connecting pieces 26. The other side of the connecting piece 26 is fixedly connected to the groove formed by the pressure cover 2 and the top cover 1. One power-generating device 27 can be connected to six pressure-bearing bottom plates 25 through the pressure cover 2. Each pressure-bearing bottom plate 25 can be connected to three power-generating devices 27. When one pressure-bearing bottom plate 25 descends, it will drive the three power-generating devices 27 to descend.

[0046] The working principle of this footstep pressure power generating device is: first, the device is placed stably, and the pressure-bearing base plate 25 is fixedly connected to the three power generating devices 27. At this time, the movement of one pressure-bearing base plate 25 drives the follow-up movement of the three power generating devices 27. Since the three power generating devices have the same movement, only the movement of one of the power generating devices is described.

[0047] When the pressure base plate 25 is descending, one corner of it transfers pressure to the gland, driving the gland 2 to descend and compressing the spring 9. According to calculations, the determination of the elastic coefficient of the spring 9 ensures that the maximum descent is about 1 cm, which can ensure that pedestrians do not experience large ups and downs during walking. The descent of the gland 2 drives the spur rack 10 downward, and the spur rack 10 drives the gear 12 to rotate. This in turn drives the gear shaft 11, and the second bevel gear 17 rotates. The second bevel gear 17 meshes with the first bevel gear 16 and has a speed increase ratio of 2:1, which can increase the amount of electricity produced. The first bevel gear 16 drives the ratchet shaft 18 to rotate clockwise, and the ratchet shaft 18 drives the ratchet teeth 19 to rotate. When rotating clockwise, the ratchet teeth 19 will be stuck in the groove in the ratchet disk 20, and push the ratchet disk 20 to rotate, thereby driving the motor 24 to rotate, cutting the magnetic flux lines to generate electricity.

[0048] When the pressure on the pressure bottom plate 25 disappears, the spring 9 rebounds, pushing the gland 2 up, and the gland 2 rises and drives the spur rack 10 to move up, and the spur rack 10 drives the gear 12 to rotate. Then the gear shaft 11 is driven, and the second bevel gear 17 rotates. The second bevel gear 17 meshes with the first bevel gear 16, and the first bevel gear 16 drives the ratchet shaft 18 to rotate counterclockwise, and the ratchet shaft 18 drives the ratchet teeth 19 to rotate. In the case of counterclockwise rotation, the ratchet teeth 19 will not be stuck in the groove in the ratchet disk 20, but will shrink and rotate, and will not drive the ratchet disk 20 to rotate, so the motor 24 will not rotate. The unidirectional rotation of the motor 24 facilitates the collection and storage of electric energy, reduces resistance, and relies on the elastic potential energy of the spring 9 to rebound, lift the gland 2 to the initial position, and drive the pressure bottom plate 25 back to the initial position to complete one electricity generation.

[0049] When this type of footstep pressure power generation device is working, when in use, the pedestrian's footstep pressure acts on the pressure-bearing bottom plate 25, pressing the pressure-bearing bottom plate 25 downward, causing the pressure cover 2 of the three power generation devices 27 to move downward, and through the transmission speed increase, driving the motor 24 to rotate to generate electricity. After the pedestrian's pressure on the pressure-bearing bottom plate 25 disappears, the spring 9 rebounds, causing the pressure cover 2 to rise, pushing the pressure-bearing bottom plate 25 back to the initial position, completing a complete power generation.

[0050] Embodiment 2

[0051] The difference between Example 2 and Example 1 is that the pressure bottom plates 25 are all square in shape, one power generating device 27 can be connected to four pressure bottom plates 25 through the pressure cover 2, and each pressure bottom plate 25 can be connected to four power generating devices 27. When one pressure bottom plate 25 descends, it will drive the four power generating devices 27 to descend.

[0052] Embodiment 3

[0053] The difference between the third embodiment and the first embodiment is that the pressure-bearing bottom plate 25 is in the shape of a regular hexagon.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
