However, with the increasing intelligence of vehicles, the power consumption of electronic control systems is gradually increasing, making vehicle range a pressing technical challenge that the industry needs to address.
[0003] When a vehicle travels over uneven road surfaces, it generates impacts. The suspension system transfers the kinetic energy of the impact to the vehicle body. The coil spring absorbs the impact kinetic energy and converts it into elastic potential energy, continuously reciprocating. The shock absorber generates damping force during the spring's movement, suppressing the spring's vibration, accelerating the attenuation of suspension system vibration and vehicle body vibration, and converting the kinetic energy of the vehicle body vibration into heat energy of the oil inside the shock absorber through damping, dissipating it into the surrounding environment, thereby improving the vehicle's comfort and smoothness.
[0004] In current automobiles, the vehicle's own motion during operation contains a significant amount of energy.

[0046] As described in the background section, in current automobiles, the vehicle's own motion during operation contains a wealth of energy. However, how to rationally and effectively recover and utilize this energy, and provide a considerable amount of electrical power to the local electronic control system, still needs improvement.
[0047] To address the aforementioned technical problems, embodiments of this application provide an energy recovery device, an energy supply system, and a vehicle. The energy recovery device provided in the first aspect of this application includes an elastic element, a support assembly, a shock absorber, and a pad structure. The support assembly is located at both ends of the elastic element and supports it. The shock absorber is located at one end of the elastic element. The pad structure is located between the support assembly and the elastic element, and has a piezoelectric layer and a flexible layer, with the flexible layer covering the piezoelectric layer. Thus, the energy recovery device provided in this application, by providing a pad structure with a piezoelectric layer and a flexible layer, allows the pad structure to generate electrical energy during vehicle suspension vibration through the cooperation of the shock absorber and the elastic element, thereby effectively recovering the vibration energy of the vehicle suspension during operation.
[0048] The energy supply system provided in the second aspect of this application includes a rectifier module, a filter module, a voltage regulator module, a modulation module, a protection module, an energy storage module, and the aforementioned energy feeding device. The rectifier module, filter module, voltage regulator module, modulation module, protection module, and energy storage module are electrically connected in sequence, and the transmission line of the energy feeding device is electrically connected to the rectifier module. Thus, the energy supply system provided in this application sequentially regulates the electrical energy generated by the energy feeding device through the rectifier module, filter module, voltage regulator module, modulation module, and protection module to form a stable direct current, which is then stored in the energy storage module for vehicle use.
[0049] A third aspect of this application provides a vehicle, including a vehicle body and the aforementioned power supply system, the power supply system being connected to the vehicle body.
[0050] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.
[0051] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0052] This application provides an energy feeding device, an energy supply system, and a vehicle. By setting a pad structure with a piezoelectric layer and a flexible layer, during vehicle suspension vibration, the pad structure generates electrical energy during compression through the cooperation of the shock absorber and the elastic element, thereby effectively recovering the vibration energy of the suspension during vehicle operation. The specific structure of the energy feeding device, energy supply system, and vehicle provided in this application embodiment is described below with reference to the accompanying drawings.
[0053] refer to Figure 1 as well as Figure 2 This application provides a power supply device 100 in a first aspect. The power supply device 100 may include an elastic element 200, a support assembly 300, a vibration damper 400, and a pad structure 500. In this application embodiment, the support assembly 300 may be located at both ends of the elastic element 200, thereby enabling the support assembly 300 to support the elastic element 200. In one possible implementation, such as... Figure 1 As shown, the damper 400 can be located at one end of the elastic member 200, thereby generating a damping force during the movement of the elastic member 200 to suppress the vibration of the elastic member 200. The pad structure 500 can be located between the support assembly 300 and the elastic member 200, wherein, reference... Figure 3 as well as Figure 4 The gasket structure 500 may have a piezoelectric layer 510 and a flexible layer 520, and the flexible layer 520 may cover the piezoelectric layer 510 to protect the piezoelectric layer 510.
[0054] In this embodiment, it is understood that during vehicle operation, vibrations are transmitted to the vehicle body through the suspension system due to road surface excitation. The force between the vehicle body and the ground causes the elastic element 200 to continuously compress and stretch. Correspondingly, the pad structure 500 receives the compressive force between the support component 300 and the elastic element 200, causing the piezoelectric layer 510 inside the pad structure 500 to generate electrical energy, thereby effectively recovering the vibration energy of the suspension during vehicle operation.
[0055] Based on the above embodiments, the piezoelectric layer 510 and the flexible layer 520 can be an integrally molded structure. In one possible implementation, for example, the flexible layer 520 can be made of natural rubber, and the piezoelectric layer 510 and the flexible layer 520 can be integrally molded through a vulcanization process. It is understood that the shape and material of the piezoelectric layer 510 and the flexible component can be adjusted according to the requirements of different installation structures, thereby adapting to assembly and performance requirements.
[0056] It should be noted that the piezoelectric layer 510 uses a new type of high-temperature resistant material, which maintains constant piezoelectric properties before and after the integral molding process through vulcanization. Thus, the flexible layer 520 can form a closed protection for the internal piezoelectric layer 510 and has good insulation properties. It also allows the pressure experienced by the gasket structure 500 during vehicle suspension vibration to be transmitted to the internal piezoelectric layer 510, thereby generating electrical energy in the piezoelectric layer 510 during compression.
[0057] In one possible implementation, such as Figure 5 as well as Figure 6 As shown, the gasket structure 500 can be an annular sheet structure, and the elastic element 200 can be a helical spring. Of course, in some other embodiments, the gasket structure 500 and the elastic element 200 can also be other shapes, and the embodiments of this application are not limited herein.
[0058] refer to Figure 5 Based on the above embodiments, in one possible implementation, the gasket structure 500 may include a main body 530 and an extension 540. The main body 530 may be disposed close to the elastic member 200, and the extension 540 may extend radially along the outer periphery of the main body 530. In this embodiment, the end of the elastic member 200 may surround the outer surface of the main body 530 and contact the side of the extension 540 facing the elastic member 200. This allows the elastic member 200 to be wound and connected to the gasket structure 500. When the elastic member 200 is compressed, the compressive force can be further transmitted to the gasket structure 500, facilitating the generation of electrical energy by the piezoelectric layer 510.
[0059] Continue to refer to Figure 1 as well as Figure 2 Based on the above embodiments, in one possible implementation, the support component 300 may further include a first support member 310 and a second support member 320. In this embodiment, the first support member 310 and the second support member 320 may be located at opposite ends of the elastic member 200. It is understood that the first support member 310 and the second support member 320 are capable of supporting the elastic member 200.
[0060] For example, the first support member 310 and the second support member 320 can be a mounting bracket or a tray structure. The mounting bracket can be installed on the front suspension of the vehicle, while the tray structure can be installed on the rear suspension. Of course, in other embodiments, the first support member 310 and the second support member 320 can also be other structures, and this application embodiment is not limited thereto.
[0061] Continue to refer to Figure 1 as well as Figure 2Based on the above embodiments, in one possible implementation, the gasket structure 500 may further include a first gasket 550 and a second gasket 560. In this embodiment, the first gasket 550 may be located between one end of the elastic member 200 and the first support member 310, and correspondingly, the second gasket 560 may be located between the other end of the elastic member 200 and the second support member 320. This facilitates the generation of electrical energy by the first gasket 550 and the second gasket 560 during the compression process.
[0062] Continue to refer to Figure 4 Based on the above embodiments, the power supply device 100 may further include a transmission line 600. The number of transmission lines 600 may be one or more, and this embodiment is not limited thereto. In one possible implementation, a first through hole 551 may be formed on the first gasket 550, and correspondingly, a second through hole 561 may be formed on the second gasket 560. It is understood that one end of the transmission line 600 may pass through the first through hole 551, while the other end may pass through the second through hole 561 and extend to the outside of the power supply device 100. In this way, the transmission line 600 can be inserted inside the elastic member 200, and the first gasket 550 and the second gasket 560 are electrically connected through the transmission line 600, thereby simplifying wiring and preventing the transmission line 600 from being exposed to the outside and suffering wear or breakage.
[0063] Continue to refer to Figure 4 Based on the above embodiments, combined with Figure 5 It can be seen that a first through hole 551 or a second through hole 561 can be opened along the outer periphery of the main body 530 and the extension 540, and the size of the first through hole 551 or the second through hole 561 should be greater than or equal to the size of the transmission line 600, so as to facilitate the installation of the transmission line 600.
[0064] Continue to refer to Figure 1 Based on the above embodiments, in one possible implementation, the elastic element 200 and the vibration damper 400 can be an integral structure. In this embodiment, the vibration damper 400 can pass through the support assembly 300 and the pad structure 500, and be fixedly connected to the elastic element 200, thereby making the vibration damper 400 and the elastic element 200 form an integral structure. In this way, by directly connecting the vibration damper 400 and the elastic element 200, the vibration damper 400 generates a damping force during the movement of the elastic element 200, thereby suppressing the vibration of the elastic element 200.
[0065] Understandably, the integrated elastic element 200 and shock absorber 400 are commonly used in the front suspension of vehicles. One end of the elastic element 200 is connected to the vehicle body, and the other end is connected to the shock absorber 400, while the other end of the shock absorber 400 is connected to the brake. Considering the internal space constraints of the front suspension, the elastic element 200 and shock absorber 400 are designed as an integrated structure, thus saving some internal space.
[0066] Continue to refer to Figure 2 Based on the above embodiments, in another possible implementation, the elastic element 200 and the damper 400 can be separate structures. In this embodiment, the damper 400 can be transmitted to the elastic element 200 through a transmission component, thereby indirectly connecting the damper 400 and the elastic element 200, so that the damper 400 generates a damping force during the movement of the elastic element 200 to suppress the vibration of the elastic element 200.
[0067] Understandably, the split-structure elastic element 200 and shock absorber 400 are typically used in the rear suspension of vehicles. The elastic element 200 is connected to the vehicle body, and both the elastic element 200 and the support assembly 300 are located within the lower control arm of the vehicle. The shock absorber 400 is connected to the brake, and is indirectly connected to the elastic element 200 through the brake, control arm, support assembly 300, and support assembly 300. Because the internal space of the rear suspension is relatively ample, the elastic element 200 and shock absorber 400 are designed as a split structure to meet the installation requirements of both.
[0068] refer to Figure 7 This application provides a second aspect of a power supply system 700. The power supply system 700 may include a rectifier module 710, a filter module 720, a voltage regulator module 730, a modulation module 740, a protection module 750, an energy storage module 760, and the aforementioned energy feeding device 100. In this application embodiment, the rectifier module 710, filter module 720, voltage regulator module 730, modulation module 740, protection module 750, and energy storage module 760 are sequentially and electrically connected, and the extended end of the transmission line 600 of the energy feeding device 100 is electrically connected to the rectifier module 710. Thus, the power supply system 700 provided in this application embodiment can sequentially regulate the electrical energy generated by the energy feeding device 100 through the rectifier module 710, filter module 720, voltage regulator module 730, modulation module 740, and protection module 750, modulating the unstable AC power into stable DC power, which is then stored in the energy storage module 760 for vehicle use.
[0069] Continue to refer to Figure 7Based on the above embodiments, the rectifier module 710 may include a full-bridge rectifier circuit. In one possible implementation, the full-bridge rectifier circuit may be a circuit composed of diodes, and the number of diodes can be several; this application embodiment is not limited thereto. In this application embodiment, for example, the number of diodes can be four, then the full-bridge rectifier circuit can be a circuit composed of four diodes. It is understood that the rectifier module 710 can convert the alternating current generated by the power supply device 100 into direct current through the transmission line 600, thereby supplying it to the energy storage module 760.
[0070] Continue to refer to Figure 7 Based on the above embodiments, the filter module 720 may include a capacitor, which is connected in parallel with the rectifier module 710. This enables voltage buffering and filters the unstable current generated by the rectifier module 710, thereby outputting a smoother and more stable DC power.
[0071] Continue to refer to Figure 7 Based on the above embodiments, it can be understood that the voltage regulator module 730 can further regulate the DC power output by the filter module 720, thereby outputting a fixed value of DC power.
[0072] Continue to refer to Figure 7 Based on the above embodiments, it is understood that the modulation module 740 may include an integrated operational amplifier circuit. It is also understood that when the current output by the voltage regulator module 730 is insufficient to directly drive the energy storage module 760 for charging, and the current output by the voltage regulator module 730 does not reach the charging threshold current of the energy storage module 760, the modulation module 740 can amplify the current output by the voltage regulator module 730 to the threshold range, thereby charging the energy storage module 760.
[0073] Continue to refer to Figure 7 Based on the above embodiments, it can be understood that the protection module 750 protects the energy storage module 760 to prevent the energy storage module 760 from being overcharged or over-discharged during operation, which would cause the performance of the energy storage module 760 to degrade rapidly, thereby affecting its lifespan and the normal operation of the system.
[0074] Continue to refer to Figure 7 Based on the above embodiments, it can be understood that the energy storage module 760 can be used to store the electrical energy generated by the energy feeding device 100 and supply it to the control system that needs electrical energy. Exemplarily, the energy storage module 760 can be an energy storage battery, and this application embodiment is not limited thereto.
[0075] This application provides a vehicle (not shown in the figures) in a third aspect. The vehicle may include a vehicle body (not shown in the figures) and the aforementioned power supply system 700. In this application embodiment, the power supply system 700 may be connected to the vehicle body.
[0076] In this embodiment of the application, the energy feeding device 100 provided in this embodiment of the application provides a pad structure 500 with a piezoelectric layer 510 and a flexible layer 520. During the vibration of the vehicle suspension, the pad structure 500 generates electrical energy during the compression process through the cooperation of the shock absorber 400 and the elastic element 200, thereby reasonably and effectively recovering the vibration energy of the suspension during vehicle operation.
[0077] In this embodiment, the energy feeding device 100 provided is simple in structure, low in cost, and easy to implement in engineering. Furthermore, the energy feeding device 100 can be adapted to the suspension structure and shape of a vehicle. With the necessary power supply system 700 configured, it can generate continuous and stable electrical energy during vehicle operation, thereby forming an effective self-generating energy feeding system.
