Description

Technical Field

[0001] This application relates to the technical field of vehicle power generation, and in particular to a vehicle vibration power generation system. Background Technology

[0002] The automotive suspension is a collective term for all force-transmitting connections between the vehicle's frame (or monocoque chassis) and axles (or wheels). It includes components such as shock absorbers, suspension springs, anti-roll bars, suspension subframes, lower control arms, longitudinal struts, steering knuckles, rubber bushings, and linkages. Its function is to transmit forces and torques acting between the wheels and the frame, and to buffer the impact forces transmitted from uneven road surfaces to the frame or body. When a car travels on the road, it experiences vibrations and impacts due to changes in the ground surface. A portion of these impact forces is absorbed by the tires, but the vast majority is absorbed by the suspension system between the tires and the body. Most of the mechanical energy generated by vehicle vibrations is absorbed by the shock absorbers and suspension springs and converted into heat energy. To avoid this energy loss, the inventors developed a vehicle vibration power generation system. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a vehicle vibration power generation system, which has the advantage of being able to extract the vibration stroke during vehicle operation and use it for power generation, thereby achieving energy conservation and environmental protection.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A vehicle vibration power generation system includes a vibration output mechanism for outputting vehicle vibration stroke, a stroke amplification mechanism connected to the vibration output mechanism, and a generator connected to the stroke amplification mechanism.

[0006] The vibration discharge mechanism includes an upper stroke discharge component and a lower stroke discharge component. The upper stroke discharge component includes an upper cable for connecting with the suspension system, and an upper transmission component for mutual transmission is provided between the upper cable and the stroke amplification mechanism.

[0007] To achieve the above technical solution, the upper stroke output component for the compression stroke of the vehicle body suspension system and the lower stroke output component for the rebound stroke of the vehicle body suspension system are used to output the vibration stroke during the vehicle's travel and then send them to the stroke amplification mechanism. The stroke amplification mechanism amplifies the stroke and then uses it to amplify the generator to generate electricity.

[0008] As a preferred embodiment of this application, the upper cable component includes an upper cable core and an upper outer shell sleeved on the upper cable core. The two ends of the upper cable core are respectively connected to the suspension system and the upper transmission component, and the two ends of the upper outer shell are respectively fixed to the vehicle frame and the stroke amplification mechanism.

[0009] By implementing the above technical solution, when the vehicle body's downward suspension system contracts, the connection point between the upper cable core and the suspension system moves downward relative to the connection point between the upper shell and the frame, thereby causing the upper cable core to pull the upper transmission component to move.

[0010] As a preferred embodiment of this application, the upper transmission component includes an upper transmission sprocket, which is connected to the input shaft of the stroke amplification mechanism via a one-way bearing. An upper chain is provided on the upper transmission sprocket, one end of which is connected to the upper cable core, and the other end is fixedly connected to the upper transmission sprocket. An upper reset assembly is provided between the upper transmission sprocket and the outer shell of the stroke amplification mechanism.

[0011] The above technical solution enables the upper cable core to move downward relative to the connection point between the upper outer shell and the frame when the vehicle body's downward suspension system contracts. This causes the upper cable core to pull the upper chain, thereby driving the upper transmission sprocket to rotate. This, in turn, drives the input shaft of the stroke amplification mechanism to rotate. As a result, the micro-stroke of the vehicle body's downward suspension system contraction is guided through the upper cable core to the stroke amplification mechanism. Then, the stroke amplification mechanism amplifies and speeds up the process to drive the generator to rotate and generate electricity.

[0012] As a preferred embodiment of this application, an upper adjusting screw sleeve is fixed at one end of the upper outer shell connected to the frame, and an upper retaining sleeve is fixed on the frame for the adjusting screw sleeve to pass through. An upper adjusting nut is screwed onto the upper adjusting screw sleeve, and the upper adjusting nut abuts against the retaining sleeve.

[0013] To achieve the above technical solution, the position of the adjusting nut on the ground of the upper adjusting screw sleeve is adjusted, thereby adjusting the position of the upper adjusting screw sleeve fixed on the frame, which in turn increases the length of the upper outer shell. This causes the upper cable core to become taut due to the increase in the wiring trajectory, and conversely, it can relax the overly taut upper cable core.

[0014] As a preferred embodiment of this application, the upper reset assembly includes an upper reset spring, one end of which is fixedly connected to the upper transmission sprocket, and the other end is fixedly connected to the housing of the stroke amplification mechanism.

[0015] To achieve the above technical solution, when the vehicle body moves down and the suspension system retracts, the upper pull cable core is not under force. At this time, the upper return spring can drive the upper transmission sprocket to rotate in the opposite direction to reset, so that the upper pull cable core can be pulled to work again next time.

[0016] As a preferred embodiment of this application, the lower stroke output component includes a lower cable for connection with the suspension system, and a lower transmission component for mutual transmission is provided between the lower cable and the stroke amplification mechanism.

[0017] The above technical solution is used to guide the rebound of the vehicle body and the extension stroke of the suspension system.

[0018] As a preferred embodiment of this application, the pull cable component includes a pull cable core and a lower outer shell sleeved under the pull cable core. A frame extension bracket is provided on the frame, and a suspension extension bracket is provided on the suspension system. The two ends of the pull cable core are respectively connected to the frame extension bracket and the lower transmission component. The two ends of the lower outer shell are respectively fixed to the suspension extension bracket and the stroke amplification mechanism. The connection point between the pull cable core and the frame extension bracket is lower than the connection point between the lower outer shell and the suspension extension bracket.

[0019] The above technical solution enables the lower outer shell and the suspension extension bracket to move downward relative to the connection point between the cable and the frame extension bracket when the suspension system rebounds. This causes the lower cable core to pull the lower transmission component to move.

[0020] As a preferred embodiment of this application, the lower transmission component includes a lower transmission sprocket, which is connected to the input shaft of the stroke amplification mechanism via a one-way bearing. A lower chain is provided below the lower transmission sprocket, with one end of the lower chain connected to the lower pull cable core and the other end fixedly connected to the lower transmission sprocket. A lower reset assembly is provided between the lower transmission sprocket and the outer shell of the stroke amplification mechanism.

[0021] The above technical solution enables the lower outer shell and the suspension extension bracket to move downward relative to the connection point between the cable and the frame extension bracket when the suspension system rebounds. This causes the lower cable core to pull the lower transmission component to move.

[0022] As a preferred embodiment of this application, a lower adjusting sleeve is fixed at one end of the lower outer shell connected to the suspension extension bracket, a lower retaining sleeve for the adjusting sleeve to pass through is fixed at the lower end of the suspension extension bracket, and a lower adjusting nut is screwed onto the lower adjusting sleeve, with the lower adjusting nut abutting against the retaining sleeve.

[0023] To achieve the above technical solution, when the vehicle body lifts and the suspension system rebounds, the lower outer shell and the suspension extension bracket point in the figure move downward relative to the connection point between the cable and the frame extension bracket. This causes the lower cable core to pull the lower chain, thereby driving the lower transmission sprocket to rotate. This, in turn, drives the input shaft of the stroke amplification mechanism to rotate, allowing the micro-stroke of the vehicle body lifting and the suspension system rebounding to be guided into the stroke amplification mechanism through the lower cable core. Then, the stroke amplification mechanism amplifies and speeds up the process to drive the generator to rotate and generate electricity.

[0024] As a preferred embodiment of this application, the upper reset assembly includes an upper reset spring, one end of which is fixedly connected to the upper transmission sprocket, and the other end is fixedly connected to the housing of the stroke amplification mechanism.

[0025] To achieve the above technical solution, when the vehicle body lowering suspension system retracts, the lower cable core is not under force. At this time, the lower return spring can drive the lower transmission sprocket to rotate in the opposite direction to reset, ready for the next pull of the lower cable core to perform work. When the vehicle body lowering suspension system retracts, the upper stroke guide component drives the stroke amplification mechanism to perform work, thereby realizing a cyclical effect.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This allows the vehicle's vertical vibrations during driving to drive the stroke amplification mechanism via the upper and lower stroke output components, thereby achieving the effect of cyclic power generation;

[0028] 2. This power generation system can be added to existing vehicles without damaging their structure, thus enabling its installation on different vehicles and improving the overall adaptability of the power generation system. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a vehicle vibration power generation system. (Refer to...) Figure 1 and Figure 2 The vehicle vibration power generation system includes a vibration extraction mechanism 1 for deriving the vehicle's vibration stroke, a stroke amplification mechanism 2 connected to the vibration extraction mechanism, and a generator 3 connected to the stroke amplification mechanism 2. The stroke amplification mechanism 2 can be a rack and pinion type, a chain drive type, a synchronous belt drive type, or a rope pulley mechanism. In this embodiment, it is a speed increaser type of rack and pinion, which has a simple structure, precise transmission ratio, and mature technology. The input shaft of the generator 3 is connected to the output shaft of the speed increaser, so that the vibration extraction mechanism 1 amplifies the vehicle's vibration stroke through the stroke amplification mechanism 2 to drive the generator 3 to rotate and generate electricity.

[0037] Reference Figure 2 and Figure 3 The vibration discharge mechanism 1 includes an upper stroke discharge assembly 11 for discharging the downward travel of the suspension system 5 under the vehicle body and a lower stroke discharge assembly 12 for discharging the upward travel of the suspension system 5 under the vehicle body and the upward travel of the suspension system 5. The upper stroke discharge assembly 11 includes an upper cable for connecting to the suspension system 5, and an upper transmission member 112 for mutual transmission is provided between the upper cable and the stroke amplification mechanism 2. The lower stroke discharge assembly 12 includes a lower cable for connecting to the suspension system 5, and a lower transmission member 122 for mutual transmission is provided between the lower cable and the stroke amplification mechanism 2.

[0038] Reference Figure 2 and Figure 3The upper cable component 111 includes an upper cable core 1111 and an upper outer shell 1112 sleeved on the upper cable core 1111. Both ends of the upper cable core 1111 are connected to the suspension system 5 and the upper transmission component 112, respectively (as shown in the figure, the connection point between the upper cable core 1111 and the suspension system 5 is point A, and the connection point with the upper transmission component 112 is point D). Both ends of the upper outer shell 1112 are fixed to the vehicle frame and the stroke amplification mechanism 2, respectively. One end of the upper outer shell 1112 is fixed with a mounting sleeve, which is fixed to the outer shell of the stroke amplification structure by screws or welding (its fixing point is point C). The end of the upper outer shell 1112 connected to the frame is fixed with an upper adjusting screw sleeve 1113. An upper retaining sleeve 1114 for the adjusting screw sleeve to pass through is fixed on the frame. An upper adjusting nut 1115 is screwed onto the upper adjusting screw sleeve 1113. The adjusting nut abuts against the retaining sleeve, that is, the upper adjusting nut 1115 abuts against the upper retaining sleeve 1114, thereby fixing one end of the shell to the frame 4 (its fixing point is point D). When the upper pull cable core 1111 is stretched after installation or after long-term use, resulting in insufficient tension and poor transmission, the position of the upper adjusting nut 1115 on the upper adjusting sleeve 1113 can be adjusted to fix the upper adjusting sleeve 1113 on the frame, thereby indirectly increasing the length of the upper outer shell 1112. This allows the upper pull cable core 1111 to be tightened due to the increased wiring path, and conversely, it can relax an overly tight upper pull cable core.

[0039] Reference Figure 2 and Figure 3The upper transmission component 112 includes an upper transmission sprocket 1121, which is connected to the input shaft of the stroke amplification mechanism 2 via a one-way bearing. This means the upper transmission sprocket 1121 can only drive the input shaft of the stroke amplification mechanism 2 to rotate in one direction. An upper chain 1122 is mounted on the upper transmission sprocket 1121. One end of the upper chain 1122 is connected to the upper cable core 1111, and the other end is fixedly connected to the upper transmission sprocket 1121. An upper reset assembly is located between the upper transmission sprocket 1121 and the housing of the stroke amplification mechanism 2. The upper reset component is an upper reset spring 1123. One end of the upper reset spring 1123 is fixedly connected to the upper transmission sprocket 1121, and the other end is fixed to the housing of the stroke amplification mechanism 2. When the vehicle body lowering suspension system 5 retracts, point A in the diagram moves downward relative to point B, causing the upper pull cable core 1111 to pull point D, which in turn pulls the upper chain 1122, driving the upper transmission sprocket 1121 to rotate. This, in turn, drives the input shaft of the stroke amplification mechanism 2 to rotate, allowing the micro-stroke of the vehicle body lowering suspension system 5 to be guided through the upper pull cable core 1111 to the stroke amplification mechanism 2. The stroke amplification mechanism 2 then amplifies and speeds up the stroke, driving the generator 3 to generate electricity. When the vehicle body lowering suspension system 5 retracts, the upper pull cable core 1111 is not under force. At this time, the upper reset spring 1123 can drive the upper transmission sprocket 1121 to rotate in the opposite direction and reset, ready for the next pull of the upper pull cable core 1111.

[0040] Reference Figure 2 and Figure 4 The pull-down cable component 121 includes a pull-down cable core 1211 and a lower outer shell 1212 sleeved under the pull-down cable core 1211. A frame extension bracket 1216 is provided on the frame 4, and a suspension extension bracket 1217 is provided on the suspension system 5. The two ends of the pull-down cable core are respectively connected to the frame extension bracket 1216 and the lower transmission component 122 (the connection point between the pull-down cable core and the frame extension bracket 1216 is point F, and the connection point between the pull-down cable core and the lower transmission component 122 is point G). The connection point between the pull-down cable core and the frame extension bracket 1216 is lower than the connection point between the lower outer shell 1212 and the suspension extension bracket 1217.

[0041] Reference Figure 2 and Figure 4One end of the lower outer shell 1212 is fixed with a mounting sleeve, which is fixed to the lower outer shell of the stroke amplification structure by screws or welding (its fixing point is point H). The end of the lower outer shell 1212 connected to the suspension extension bracket 1217 is fixed with a lower adjusting screw sleeve 1213. The lower suspension extension bracket 1217 is fixed with a lower retaining sleeve 1214 for the lower adjusting screw sleeve 1213 to pass through. A lower adjusting nut 1215 is screwed onto the lower adjusting screw sleeve 1213. The lower adjusting nut 1215 abuts against the lower retaining sleeve 1214, that is, the lower adjusting nut 1215 abuts against the lower retaining sleeve 1214, so that one end of the lower outer shell 1212 is fixed to the upper surface of the suspension extension bracket 1217 (its fixing point is point E). When the pull cable core 1211 is stretched after installation or after long-term use, resulting in insufficient tension and poor transmission, the position of the lower adjusting nut 1215 under the lower adjusting sleeving 1213 can be adjusted. This adjusts the position of the lower adjusting sleeving 1213 fixed on the suspension extension bracket 1217, thereby indirectly increasing the length of the lower outer shell 1212. As a result, the pull cable core 1211 becomes tensioned due to the increased wiring trajectory. Conversely, it can relax an overly tight pull cable core.

[0042] Reference Figure 2 and Figure 4 The lower transmission component 122 includes a lower transmission sprocket 1221, which is connected to the input shaft of the stroke amplification mechanism 2 via a one-way bearing. This means the lower transmission sprocket 1221 can only drive the input shaft of the stroke amplification mechanism 2 to rotate in one direction. A lower chain 1222 is disposed below the lower transmission sprocket 1221. One end of the lower chain 1222 is connected to the lower cable core 1211, and the other end is fixedly connected to the lower transmission sprocket 1221. A lower reset assembly is disposed between the lower transmission sprocket 1221 and the housing of the stroke amplification mechanism 2. The lower reset component is a lower reset spring 1223. One end of the lower reset spring 1223 is fixedly connected to the lower drive sprocket 1221, and the other end is fixed to the underside of the travel amplification mechanism 2. This causes point E in the diagram to move downwards relative to point F when the vehicle body lifting suspension system 5 rebounds. This causes the lower cable core 1211 to pull point G, which in turn pulls the lower chain 1222, driving the lower drive sprocket 1221 to rotate. This, in turn, drives the input shaft of the travel amplification mechanism 2 to rotate, allowing the micro-travel of the vehicle body lifting suspension system 5 to be guided through the lower cable core 1211 to the travel amplification mechanism 2. The travel amplification mechanism 2 then amplifies and speeds up the travel, driving the generator 3 to generate electricity. When the vehicle body lowering suspension system 5 retracts, the lower cable core 1211 is no longer under force. At this time, the lower reset spring 1223 can drive the lower drive sprocket 1221 to rotate in the opposite direction and reset, ready for the next pull of the lower cable core 1211. When the vehicle body moves down and the suspension system 5 retracts, the upper stroke output component 11 drives the stroke amplification mechanism 2 to perform work, thereby achieving a cyclical effect.

[0043] The implementation principle of a vehicle vibration power generation system according to an embodiment of this application is as follows: When the vehicle body downward suspension system 5 contracts, point A in the figure moves downward relative to point B, causing the upper pull cable core 1111 to pull point D to move, which in turn drives the upper chain 1122 to be pulled, thereby driving the upper transmission sprocket 1121 to rotate, which in turn drives the input shaft of the stroke amplification mechanism 2 to rotate, so that the micro-stroke of the contraction of the vehicle body downward suspension system 5 is introduced into the stroke amplification mechanism 2 through the upper pull cable core 1111, and then only the stroke amplification mechanism 2 amplifies and increases the speed to drive the generator 3 to rotate and generate electricity. When the vehicle body upward suspension system 5 rebounds, point E in the figure moves downward relative to point F, causing the lower pull cable core 1211 to pull point G to move, which in turn drives the lower chain 1222 to be pulled, thereby driving the lower transmission sprocket 1221 to rotate, which drives the input shaft of the stroke amplification mechanism 2 to rotate, so that the micro-stroke of the rebound of the vehicle body upward suspension system 5 is introduced into the stroke amplification mechanism 2 through the lower pull cable core 1211, and then only the stroke amplification mechanism 2 amplifies and increases the speed to drive the generator 3 to rotate and generate electricity. This allows the vertical vibrations of the vehicle body during driving to be amplified by the upper stroke output component 11 and the lower stroke output component 12, thereby achieving a cyclic power generation effect. Furthermore, this power generation system can be added to existing vehicles without damaging their structure, thus enabling its installation on different vehicles and improving the overall adaptability of the power generation system.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
