Description

Technical Field

[0001] An embodiment of the present invention relates to an energy harvesting system utilizing linear kinetic energy based on induction power generation. Background Art

[0002] A large number of sensors are used in industrial sites. In the past, most sensor power supplies were connected and used in a wired manner, but due to the burden of material costs and wiring work time, there is a trend of gradually changing to wireless. For wireless devices, internal batteries are used. If the battery is discharged, it needs to be replaced with a new battery or charged. Even if the product is made of low power, the battery replacement and charging cycle can only reach 2 to 3 years.

[0003] Although sensors used in industrial sites are trending from wired to wireless, they are not widely used because of their short service life. Even if they have a long service life, the data transmission cycle is once every 30 minutes or once every hour, which is long and not continuous enough. If sensor data needs to be transmitted in real time, the battery life is not long enough, and the battery must be replaced or charged in order to use it again. Therefore, during the battery replacement or charging period, industrial equipment cannot be operated, resulting in losses.

[0004] The above information disclosed in this background art is only for enhancement of understanding of the background of the invention and therefore it may include information that does not constitute prior art. Summary of the invention

[0042] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. The following embodiments may be modified into a variety of different forms, and the scope of the present invention is not limited to the following embodiments. Instead, these embodiments are provided to make the present disclosure more substantial and complete, and to fully convey the ideas of the present invention to practitioners.

[0044] In addition, in the following drawings, the thickness or size of each layer is exaggerated for the convenience and clarity of explanation, and the same reference numerals refer to the same elements in the drawings. As used in this specification, the term "and / or" includes all combinations of one or more of the corresponding listed items. In addition, in this specification, the meaning of "connection" not only means the situation where the A component is directly connected to the B component, but also means the situation where the C component is located between the A component and the B component and the A component and the B component are indirectly connected.

[0045] The terms used in this specification are used to describe specific embodiments and are not intended to limit the present invention. As used in this specification, the singular form may include the plural form if the context does not clearly indicate a different situation. In addition, the terms "comprise, include" and / or "comprising, including" used in this specification specify the existence of the mentioned shapes, numbers, steps, actions, components, elements and / or their combinations, and do not exclude the existence or addition of one or more other shapes, numbers, actions, components, elements and / or combinations.

[0046] In this specification, the terms first, second, etc. are used to describe various components, parts, regions, layers and / or parts, but it is self-evident that these components, parts, regions, layers and / or parts are not limited by these terms. These terms are only used to distinguish one component, component, region, layer or part from another region, layer or part. Therefore, the first component, component, region, layer or part described in detail below can refer to the second component, component, region, layer or part without exceeding the purpose of the present invention.

[0047] In order to easily understand the relationship between one element or feature illustrated in the accompanying drawings and another element or feature, spatially related terms such as "beneath", "below", "lower", "above", and "upper" may be used. Such spatially related terms are used to easily understand the present invention based on the various process states or usage states of the present invention, and are not used to limit the present invention. For example, if the elements or features of the accompanying drawings are reversed, the elements or features described as "below" or "below" become "upper" or "above". Therefore, "below" is a concept that includes "upper" or "below".

[0048] On the other hand, the main elements used for energy collection are piezoelectric elements, thermoelectric elements, electromagnetic induction, solar panels, etc. Most of the research on energy collection focuses on improving the efficiency of elements. However, it is far from enough to produce electricity by using only such elements to replace batteries. Moreover, these elements are greatly affected by the surrounding environment. For piezoelectric elements, an external force that can be applied to deform is required, and for thermoelectric elements, the greater the temperature difference between the two sides, the higher the efficiency. For solar energy, it can only be used in bright places. The typical methods used in power plants to produce electricity are electromagnetic induction and solar power generation. In the case of both elements, the electricity that can be produced is higher than that of piezoelectric elements and thermoelectric elements. However, for solar energy, there is a disadvantage that it needs to be cleaned periodically so that the light-receiving area is not polluted, and if a large amount of heat is received, the efficiency decreases. For electromagnetic induction, as long as there is energy that can drive the turbine, it can be used regardless of the surrounding environment.

[0049] Figure 1a to Figure 1d is a schematic diagram of various energy harvesting systems.

[0050] -Self-generating bell (refer to Figure 1a )

[0051] When the bell is pressed, the transmitter uses the power generated by electromagnetic induction inside to wirelessly transmit the signal. When the receiver receives the signal, it drives the speaker and rings the bell. Due to this structure, the transmitter of the bell can be used semi-permanently. However, the transmitter only operates when the button is pressed, while the receiver is always powered by the adapter.

[0052] -Wireless temperature and humidity sensor (refer to Figure 1b )

[0053] The batteries installed in wireless sensors are primary batteries that cannot be recharged but only discharged. The life span varies greatly depending on the communication cycle.

[0054] -Wireless vibration measurement sensor (ref. Figure 1c )

[0055] The battery life is roughly 6 to 8 years, but the data transmission cycle is 1 hour, with data transmitted once an hour.

[0056] -Thermocouple temperature sensor (refer to Figure 1b )

[0057] Thermocouples are industrial temperature sensors that can measure high temperatures above 300 degrees Celsius. This product transmits data from the sensor wirelessly, and the gateway that receives the data uses an adapter. The battery life of the wireless sensor is approximately 6 months.

[0058] Figure 2a and Figure 2b Schematic diagram of an example of a working cylinder equipped with an energy collection system utilizing linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0059] like Figure 2a and Figure 2b As shown, the energy collection system using linear kinetic energy based on inductive power generation according to the embodiment of the present invention can, for example, wirelessly supply power to a magnetic field sensor for checking the operating status of an air compressor or hydraulic cylinder used in a clamping fixture in an automobile production workshop. The so-called clamping fixture is a tool for grasping a panel for welding or applying silicone.

[0060] For reference, Figure 2a This is a photo of a side panel of a vehicle being placed on a jig for welding. At this time, the cylinder is in the open state (retracted state). Figure 2b This is a photo of welding a panel fixed to a jig. At this time, the working cylinder is in the closed state (advanced state).

[0061] Figure 3 Schematic diagram of a working cylinder equipped with an energy collection system utilizing linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0062] like Figure 3 As shown, the reason why it is possible to sense whether the cylinder 200 is in the forward state or the backward state is because a magnet is inserted into the cylinder 200 and the magnetic field sensor 300 senses the magnet.

[0063] like Figure 3 As shown, two magnetic field sensing sensors 300 are installed on both sides of the main body of the working cylinder 200. According to the values ​​of the two magnetic field sensors 300, it is possible to know whether the working cylinder 200 is in the forward state or the backward state. If only 1 to 2 working cylinders are used, there is no need to charge the battery wirelessly.

[0064] However, if a large number of cylinders are used, two magnetic field sensors need to be attached to each cylinder, and a power source needs to be connected for power supply, which requires a lot of cost and time. Therefore, it is necessary to reduce such material cost and the time required for connecting the power source.

[0065] Figure 4 FIG. 1 is a schematic diagram of an energy collection system 100 utilizing linear kinetic energy based on inductive power generation according to an embodiment of the present invention.

[0066] like Figure 4 As shown, the energy collection system 100 based on induction power generation and utilizing linear kinetic energy according to the embodiment of the present invention may include an axis fixing assembly 110 , a buffer spring assembly 120 , a rack 130 , a main body fixing assembly 140 , a spur gear 150 , a generator 160 , and a battery 170 .

[0067] In some examples, the energy collection system 100 based on inductive power generation and utilizing linear kinetic energy of an embodiment of the present invention may also include an AC-DC converter (or full-wave rectifier circuit) 180 and a battery monitoring system (BMS or constant voltage circuit) 190.

[0068] The shaft fixing assembly 110 can be fixed to the cylinder shaft 210 that performs linear motion, especially to the shaft head 211, by a fixing member. Therefore, when the cylinder shaft 210 performs linear motion back and forth from the cylinder body 220, the shaft fixing assembly 110 also performs linear motion back and forth.

[0069] The buffer spring assembly 120 can be combined with the shaft fixing assembly 110 in a state where the spring 125 is placed in the middle. When the shaft fixing assembly 110 reciprocates along with the reciprocating linear motion of the working cylinder shaft 210, the buffer spring assembly 120 reciprocates in a delayed state. Therefore, although the shaft fixing assembly 110 reciprocates at high speed, the buffer spring assembly 120 will not be damaged.

[0070] The rack 130 may extend from the buffer spring assembly 120 to the cylinder body 220 in a substantially straight line. The rack 130 performs a reciprocating linear motion together with the cylinder shaft 210 when the reciprocating linear motion is performed. The rack 130 may include a plurality of teeth 131 along one side surface, which is coupled to the spur gear 150 described below to rotate the spur gear 150.

[0071] The main body fixing assembly 140 can be fixed to the working cylinder body 220 that makes the working cylinder shaft 210 move linearly through a fixing member. Among them, the rack 130 can pass through the main body fixing assembly 140 and move linearly.

[0072] The spur gear 150 is rotatably mounted on the main body fixing assembly 140 and is engaged with the rack 130 to perform a rotational motion. That is, the spur gear 150 converts the linear motion of the rack 130 into a circular motion or a rotational motion.

[0073] The generator 160 meshes with the spur gear 150 to generate electricity (for example, alternating current). That is, the rack 130 performs a reciprocating linear motion, and thus the spur gear 150 also performs a reciprocating rotational motion, so that the generator 160 generates alternating current.

[0074] The battery 170 is electrically connected to the generator 160 for charging, and can also supply power (discharge) to the magnetic field sensor installed on the working cylinder body 220. In some examples, the battery 170 may include a lithium ion battery, a lithium ion polymer battery, and a lithium polymer battery. In addition, in the present invention, the battery 170 may also include a capacitor such as a super capacitor.

[0075] On the other hand, the AC-DC converter 180 may be electrically connected between the generator 160 and the battery 170. The AC-DC converter 180 converts the AC generated by the generator 160 into DC to charge the battery 170 or supply DC power to the sensor.

[0076] The input of the battery monitoring system (BMS) 190 can be connected to the AC-DC converter 180, and the output is connected to the sensor. The battery monitoring system 190 controls the charging voltage of the battery 170 through the AC-DC converter 180, and controls the discharging voltage of the battery 170 consumed by the sensor.

[0077] As described above, the energy collection system 100 using linear kinetic energy based on inductive power generation according to an embodiment of the present invention uses the force and energy generated by the pneumatic (or hydraulic) working cylinder 200 during reciprocating linear motion to autonomously charge the battery 170. Unlike existing products, it can be used semi-permanently while reducing the communication cycle of the sensor.

[0078] Figure 5a to Figure 5c Schematic diagram of the shaft fixing assembly 110 and the head 211 of the energy collection system 100 using linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0079] like Figure 5a to Figure 5c As shown, in the energy collection system 100 using linear kinetic energy based on induction power generation according to the embodiment of the present invention, the lower end of the shaft fixing assembly 110 can be fixed to the head 211 of the working cylinder shaft 210 by a fixing member such as a bolt / nut. Therefore, as the working cylinder shaft 210 reciprocates in linear motion, the shaft fixing assembly 110 also stably reciprocates in linear motion.

[0080] Figure 6 Schematic diagram of a buffer spring assembly 120 and a rack 130 in an energy collection system 100 utilizing linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0081] like Figure 6 As shown, in the energy collection system 100 based on induction power generation and utilizing linear kinetic energy according to the embodiment of the present invention, the buffer spring assembly 120 and the rack 130 can be formed integrally. In some examples, the buffer spring assembly 120 and the rack 130 can be formed separately and then assembled into one.

[0082] In addition, in some examples, the buffer spring assembly 120 may include: a second end plate 121; a first guide member 122, wherein the first guide member 122 extends in a straight line from the second end plate 121 to one side; and a second guide member 124, wherein the second guide member 124 extends from the second end plate 121, is connected to the first guide member 122, and is formed with a cut groove 123.

[0083] On the other hand, the rack 130 may extend substantially in a straight line from the second end plate 121 to the other side, and may include a plurality of teeth 131 on one side.

[0084] Figure 7 Schematic diagram of a main body fixing assembly 140 in an energy collection system 100 utilizing linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0085] like Figure 7 As shown, in the energy collection system 100 based on induction power generation and utilizing linear kinetic energy according to an embodiment of the present invention, the main body fixing assembly 140 can be fixed to the working cylinder body 220. In some examples, the main body fixing assembly 140 can include an upper plate assembly 141 and a lower plate assembly 142. In some examples, the rack 130 is combined with the upper plate assembly 141 in a through-through manner and capable of reciprocating linear motion, and the flat gear 150, the generator 160, the AC-DC converter 180, the battery monitoring system 190 and the battery 170 can be installed at a predetermined position. Moreover, the upper plate assembly 141 is placed on the lower plate assembly 142, and the lower plate assembly 142 can be fixed to the working cylinder body 220 by means of a fixing member such as a plurality of nylon cable ties.

[0086] Figure 8 Schematic diagram of a generator 160 in an energy collection system 100 utilizing linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0087] like Figure 8 As shown, in the energy collection system 100 using linear kinetic energy based on inductive power generation according to an embodiment of the present invention, the generator 160 may include a reduction gear generator (or motor) 160. In some examples, the reduction gear generator 160 may have a reduction ratio of approximately 150:1. That is, when the generator 160 rotates 150 times, the shaft coupled to the generator 160 rotates one circle. Conversely, when the shaft coupled to the spur gear rotates 1 circle, the generator 160 rotates 150 circles. Therefore, even at a very small number of revolutions, the generator 160 can perform a large number of rotations, and corresponding to the large number of rotations, more electricity can be generated.

[0088] Figures 9a to 9cIt is a schematic diagram of the shaft fixing assembly 110 and the buffer spring assembly 120 and their combined state in the energy collection system 100 using linear kinetic energy based on induction power generation according to an embodiment of the present invention.

[0089] like Figures 9a to 9c As shown, the shaft fixing assembly 110 may include: a first end plate 112 having a space 111 inside; and a fixing plate 113 , which is disposed in the space 111 of the first end plate 112 and is substantially in the shape of a circular plate.

[0090] The circular plate-shaped fixing plate 113 may be fixed to the first end plate 112 via a connecting rod 114. In some examples, the fixing plate 113 may be provided in a pair, and the connecting rod 114 may be formed at the upper and lower parts of the fixing plate 113, respectively.

[0091] On the other hand, as described above, the buffer spring assembly 120 may include: a second end plate 121; a first guide member 122, the first guide member 122 is in a straight line shape, extends from the second end plate 121, and is combined with the space 111 of the first end plate 112; a second guide member 124, the second guide member 124 is generally in a circular ring shape, extends from the second end plate 121, is connected to the first guide member 122, and is combined with the fixed plate 113. Among them, the second guide member 124 may also include a cut groove 123 formed in a region corresponding to the connecting rod 114. Moreover, the inner side of the second guide member 124 may also include a buffer spring 125 located between the second end plate 121 and the fixed plate 113.

[0092] As described above, the first guide 122 of the buffer spring assembly 120 is coupled to the inner space 111 of the shaft fixing assembly 110, and the second guide 124 of the buffer spring assembly 120 is coupled to the fixing plate 113 of the shaft fixing assembly 110, and the buffering effect can be achieved by the buffer spring 125 located between the buffer spring assembly 120 and the shaft fixing assembly 110. That is, when the cylinder shaft 210 moves linearly from the cylinder body 220, the buffer spring assembly 120 and the shaft fixing assembly 110 play a buffering role by using the buffer spring 125, thereby preventing the buffer spring assembly 120 and the shaft fixing assembly 110 from being damaged.

[0093] If there is no buffer spring 125, the reduction gear generator 160 described above rotates at the speed of closing or opening the cylinder 200. The time required for closing and opening the cylinder 200 is generally within 1 second, and the start-up is rapid. Therefore, the gear does not have enough durability to withstand the force, resulting in damage to the reduction gear generator 160.

[0094] In order to compensate for this problem, the spring 125 is used. The spring 125 is compressed by the force acting instantly, thereby absorbing the force acting, and slowly pushing by the tension of the compressed spring 125. On the contrary, if it is pulled instantly, the spring 125 becomes longer and absorbs the force, and slowly pulls due to the tension. Therefore, the spring 125 plays a buffering role.

[0095] Fig.10 Schematic diagram of the circuit structure of an energy collection system 100 utilizing linear kinetic energy based on inductive power generation according to an embodiment of the present invention.

[0096] like Fig.10 As shown, after the cylinder 200 is running, the generator (motor) 160 generates electricity, and the generated voltage is an AC voltage, which is converted into a DC voltage by means of an AC-DC converter (constant voltage circuit) 180. Then, the AC-DC converter 180 outputs a constant DC voltage of, for example, 3V.

[0097] In the circuit configuration diagram, the portion marked with reference numeral 1 is an operation when power is generated, the power output from the constant voltage circuit drives the sensor, and the remaining power is used to charge the battery 170. In other words, for example, if 100 watts of power is generated, the sensor consumes 40 watts, and the remaining 60 watts are used to charge the battery 170.

[0098] At this time, the battery monitoring system 190 plays a role in protecting the battery 170 from overcharge. That is, the battery 170 is not charged to a voltage higher than a preset voltage, thereby preventing the battery 170 from exploding or catching fire. In addition, the portion marked with reference numeral 2 illustrates the supply of power from the battery 170 to the sensor when no power is generated. At this time, the battery monitoring system 190 plays a role in protecting the battery 170 from overdischarge. That is, the battery 170 is not discharged to a voltage lower than a preset voltage, thereby preventing the battery 170 from deteriorating.

The present invention is not limited to the above embodiment.
