Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, and more particularly to a power output assembly, an active suspension system, and a vehicle. Background Technology

[0002] Active suspension is an advanced automotive technology that uses an onboard system to control the vertical movement of the wheels relative to the chassis or body to provide better ride comfort and vehicle stability.

[0003] Among related technologies, a hydraulic active suspension system is adopted, which uses a high-pressure pump to provide active power to control the stability of the vehicle body and the movement of the wheels, thereby improving comfort and handling and meeting more driving conditions. However, hydraulic transmission is slow to respond and requires more components (such as hydraulic pumps and energy storage tanks), making the system complex and expensive. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a power output assembly with a relatively simple overall structure, easy assembly, improved response speed, greater force output to the vehicle body structure, the ability to use a smaller power linear motor, reduced production cost, lower weight, and improved overall performance.

[0005] The present invention also proposes an active suspension system having the above-described power output assembly.

[0006] The present invention also proposes a vehicle having the above-described active suspension system.

[0007] According to a first aspect of the present invention, a power output assembly includes: a transition portion adapted to connect to a vehicle body structure; a linear motor including: a mover and a stator, the stator being spaced apart from the transition portion along a first direction, the stator being used to drive the mover to perform linear motion along the first direction; and an amplification mechanism including: a transmission assembly including a transmission link and a support shaft, the extension direction of the transmission link intersecting the motion direction of the mover, the transmission link having an input end and an output end, the input end being hinged to the mover, the output end being hinged to the transition portion, and the support shaft being hinged to the transmission link and fixed relative to the stator; wherein, when the mover moves to its limit position toward the transition portion, the distance from the input end to the support shaft is greater than the distance from the output end to the support shaft.

[0008] According to the power output assembly of the present invention, by setting a linear motor and an amplification mechanism, the rapid response advantage of the linear motor can be fully utilized to improve the reaction speed of the power output assembly. At the same time, the amplification mechanism can amplify the output force of the linear motor using the lever principle, so that the force output by the power output assembly to the vehicle body structure is larger. This allows the power output assembly to use a lower power linear motor, reducing the production cost of the power output assembly. Compared with the hydraulic active suspension system, the present invention does not require the setting of components such as hydraulic pumps, energy storage tanks, and hydraulic pipelines. The overall structure is simpler, easier to assemble, reduces the overall weight of the power output assembly, and improves the overall performance of the power output assembly.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The power output assembly 10 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0035] Reference Figures 1-3According to a first aspect embodiment of the present invention, the power output assembly 10 can be applied to a vehicle 100 as a power output mechanism for an active suspension system. The power output assembly 10 includes a transition section 1, a linear motor 2, and an amplification mechanism 3. The transition section 1 is adapted to connect to the vehicle body structure 40 of the vehicle 100. The linear motor 2 includes a mover 21 and a stator 22, with the stator 22 and the transition section 1 spaced apart along a first direction (refer to direction e1 in the figures). The stator 22 drives the mover 21 to perform linear motion along the first direction. Specifically, the stator 22 has a movable hole through which the mover 21 passes. For example, when the power output assembly 10 is applied to the vehicle 100, the first direction is the height direction of the vehicle 100.

[0036] The amplification mechanism 3 includes a transmission assembly 31, which includes a transmission link 311 and a support shaft 312. The extension direction of the transmission link 311 intersects the movement direction of the mover 21. The transmission link 311 has an input end 3111 and an output end 3112. The input end 3111 is hinged to the mover 21. For example, the input end 3111 can be rotatably connected to the mover 21.

[0037] The output end 3112 is hinged to the adapter 1. For example, the output end 3112 can be rotatably connected to the adapter 1, or it can be slidably connected to the adapter 1. The support shaft 312 is hinged to the transmission link 311, and the support shaft 312 is fixed relative to the stator 22. For example, the support shaft 312 can be supported on the side of the transmission link 311 away from the adapter 1, that is, the transmission link 311 rests on the support shaft 312. The support shaft 312 can also be hinged to the support shaft 312 through a shaft hole structure.

[0038] When the mover 21 moves along the first direction, the mover 21 can drive the input end 3111 to move synchronously. Since the transmission link 311 is hinged to the support shaft 312, the support shaft 312 can act as a fulcrum. When the input end 3111 moves, the transmission link 311 can rotate relative to the support shaft 312. That is, when the input end 3111 moves away from the transition part 1 in the first direction, the output end 3112 moves towards the transition part 1 in the first direction; when the input end 3111 moves towards the transition part 1 in the first direction, the output end 3112 moves away from the transition part 1 in the first direction.

[0039] It should be understood that, in order to ensure the reliability of the movement of the linear motor 2 and the transmission link 311, during the operation of the linear motor 2, when the mover 21 moves to the limit position in the direction of the transition part 1, the end of the mover 21 connected to the transmission link 311 is located on the side of the support shaft 312 away from the transition part 1 in the first direction.

[0040] When the mover 21 moves to its limit position in the direction of the adapter 1, the distance from the input end 3111 to the support shaft 312 is greater than the distance from the output end 3112 to the support shaft 312. That is, the force applied by the output end 3112 to the adapter 1 is greater than the force applied by the mover 21 to the output end 3112. In other words, the amplification mechanism 3 can amplify the force output by the mover 21.

[0041] Since the amplification mechanism 3 is a mechanical transmission, it can promptly transmit the force output by the mover 21 to the adapter 1, which in turn transmits it to the vehicle body structure 40. This fully utilizes the rapid response advantage of the linear motor 2, improving the reaction speed of the power output assembly 10. When this power output assembly 10 is installed in the active suspension system, the active suspension system can effectively control the stability of the vehicle body and the movement of the wheels, improving the comfort and handling of the vehicle 100 and meeting more driving conditions.

[0042] Meanwhile, by supporting the transmission link 311 on the support shaft 312, the amplification mechanism 3 can amplify the output force of the linear motor 2 using the lever principle, so that the force output by the power output assembly 10 to the vehicle body structure 40 is larger, so that the linear motor 2 with a smaller output power can meet the output requirements of the power output assembly 10, so that the range of linear motors 2 that can be selected for the power output assembly 10 is wider, so that the power output assembly 10 can select a smaller linear motor 2, thereby reducing the cost of the linear motor 2 and reducing the production cost of the power output assembly 10.

[0043] Compared to the hydraulic active suspension system, this invention eliminates the need for components such as hydraulic pumps, energy storage tanks, and hydraulic pipelines, resulting in a simpler overall structure that is easier to assemble. This improves the assembly efficiency of the active suspension system, reduces its production cost, and simultaneously reduces the overall weight of the power output assembly 10, the active suspension system, and the vehicle 100, thus achieving a lightweight design for the vehicle 100.

[0044] For example, the power output assembly 10 may also include a sealing assembly, which includes a fixed frame and a telescopic member. The fixed frame is connected to the stator 22, and the support shaft 312 is connected to the fixed frame, thereby achieving relative fixation between the support shaft 312 and the stator 22.

[0045] The telescopic component defines a sealed cavity. The telescopic component has a first opening and a second opening at both ends in a first direction, communicating with the sealed cavity. The stator 22 is connected and fixed to the telescopic component. The mover 21 passes through the first opening and is housed within the sealed cavity. The amplification mechanism 3 is located within the sealed cavity, and the adapter 1 covers the second opening. Specifically, the telescopic component can be a corrugated pipe. This allows the telescopic component to seal the amplification mechanism 3, reducing water or dust contamination and effectively extending its service life. Furthermore, lubricating grease can be added to the sealed cavity to lubricate the amplification mechanism 3, further extending its service life, reducing noise generated during operation, and improving the overall performance of the power output assembly 10.

[0046] According to the power output assembly 10 of the present invention, by setting a linear motor 2 and an amplification mechanism 3, the rapid response advantage of the linear motor 2 can be fully utilized to improve the reaction speed of the power output assembly 10. At the same time, the amplification mechanism 3 can amplify the output force of the linear motor 2 using the lever principle, so that the force output by the power output assembly 10 to the vehicle body structure 40 is larger. This allows the power output assembly 10 to use a lower power linear motor 2, reducing the production cost of the power output assembly 10. Compared with the hydraulic active suspension system, the present invention does not need to set up components such as hydraulic pumps, energy storage tanks, and hydraulic pipelines. The overall structure is simpler and easier to assemble, which can reduce the overall weight of the power output assembly 10 and improve the overall performance of the power output assembly 10.

[0047] Reference Figure 3 In some optional embodiments of the present invention, there are multiple amplification mechanisms 3, which are arranged at intervals along the circumference of the mover 21. This further increases the amplification effect on the output force of the mover 21, allowing even linear motors 2 with smaller output power to meet the output requirements of the power output assembly 10. This further expands the range of linear motors 2 that can be selected for the power output assembly 10, allowing the power output assembly 10 to use smaller linear motors 2, further reducing the cost of linear motors 2 and the production cost of the power output assembly 10. Simultaneously, arranging multiple amplification mechanisms 3 at intervals along the circumference of the mover 21, with each amplification mechanism 3 applying force to the mover 21 in a different direction, ensures more uniform force distribution on the mover 21, enabling the mover 21 to reliably move along the first direction, improving the smoothness of the mover 21's operation, and enhancing the operational smoothness of the power output assembly 10.

[0048] Reference Figure 1 and Figure 2According to some embodiments of the present invention, one of the output end 3112 and the adapter 1 is provided with a hinge hole 3114, and the other of the output end 3112 and the adapter 1 is provided with a rotating pin 13. The rotating pin 13 passes through the hinge hole 3114 and is rotatable along the central axis of the hinge hole 3114. For example, the output end 3112 is provided with a hinge hole 3114, and the adapter 1 is provided with a rotating pin 13. Optionally, the output end 3112 and the adapter 1 can also be connected by a ball joint structure, and the input end 3111 and the mover 21 can also be connected by a ball joint structure.

[0049] This allows the transmission link 311 to apply a force in the first direction to the adapter 1 while simultaneously applying a force in the radial direction to the adapter 1 on the mover 21. This enables the transmission link 311 and the adapter 1 to follow each other, and also enables the transmission link 311 and the vehicle body structure 40 to follow each other. This allows the power output assembly 10 to control the vehicle body structure 40 in multiple directions through the adapter 1, enabling the active suspension system to more effectively control vehicle stability and wheel movement, thereby improving the comfort and handling of the vehicle 100 and meeting more driving conditions.

[0050] Reference Figure 3 According to some embodiments of the present invention, the adapter 1 includes a slide rail 11 and a slider 12. The slide rail 11 extends along a second direction (refer to direction e2 in the figures) and is adapted to connect the vehicle body structure 40 of the vehicle 100. The second direction intersects the first direction. The slider 12 is disposed on the slide rail 11 and is slidable along the extension direction of the slide rail 11. The output end 3112 is rotatably connected to the slider 12. This allows the output end 3112 to apply a force in the first direction to the vehicle body structure 40 only through the structure of the slider 12 and the slide rail 11, that is, to control the displacement of the vehicle body structure 40 only in the first direction. This makes the control method of controlling the displacement of the vehicle body structure 40 in the first direction through the power output assembly 10 simpler and facilitates the design of the active suspension system by the developers.

[0051] Furthermore, by rotating the output end 3112 to the slider 12, the degree of freedom of the power output assembly 10 can be increased. When there are multiple amplification mechanisms 3, this can reduce the risk of multiple amplification mechanisms 3 interacting and locking up, and improve the reliability of the power output assembly 10.

[0052] At the same time, this allows the amplification effect of multiple amplification mechanisms 3 on the output force of the mover 21 to be superimposed, further amplifying the output force of the mover 21, so that the linear motor 2 with smaller output power can also meet the output requirements of the power output assembly 10, further expanding the range of linear motors 2 that can be selected for the power output assembly 10, allowing the power output assembly 10 to select linear motors 2 with smaller specifications, further reducing the cost of linear motor 2, and reducing the production cost of the power output assembly 10;

[0053] Furthermore, this allows multiple amplification mechanisms 3 to serve as redundant components, meaning that even if one amplification mechanism 3 fails, the remaining amplification mechanisms 3 can still amplify the output of the linear motor 2, effectively ensuring the reliability of the power output assembly 10.

[0054] Reference Figure 1 According to some embodiments of the present invention, a rotating hole 3113 is provided on the transmission link 311, and the support shaft 312 is rotatably inserted into the rotating hole 3113 relative to the transmission link 311. This reduces the risk of the transmission link 311 disengaging from the support shaft 312 and improves the reliability of the amplification mechanism 3. Simultaneously, this ensures that the distance from the input end 3111 to the support shaft 312 remains constant, and the distance from the output end 3112 to the support shaft 312 remains constant, thus ensuring that the amplification factor of the output force of the amplification mechanism 3 on the mover 21 remains fixed, making the force output by the linear motor 2 through the amplification mechanism 3 more stable. Furthermore, this facilitates the calculation of the displacement change of the output end 3112 in the first direction, and facilitates the control of the displacement of the transition part 1 in the first direction by controlling the displacement of the mover 21 in the first direction, thereby controlling the displacement of the vehicle body structure 40 in the first direction.

[0055] Reference Figure 2 According to some embodiments of the present invention, the transmission assembly 31 further includes a limiting member 313, which has a limiting hole 3131 and a positioning hole 3132. The transmission connecting rod 311 is slidably disposed in the limiting hole 3131, that is, the transmission connecting rod 311 is slidable relative to the limiting member 313 within the limiting hole 3131, and the support shaft 312 is rotatably disposed relative to the limiting member 313 within the positioning hole 3132. In this way, the limiting member 313 can fix the transmission connecting rod 311 relative to the support shaft 312, realizing the sliding and rotational engagement between the transmission connecting rod 311 and the support shaft 312, so that the transmission connecting rod 311 can be reliably supported on the support shaft 312, improving the reliability of the amplification mechanism 3 and the reliability of the power output assembly 10.

[0056] Reference Figure 2 and Figure 3According to some optional embodiments of the present invention, there are multiple transmission components 31, which are arranged sequentially along a first direction. It should be noted that, in this application, "multiple" means two or more. For example, there may be two, three, four or more transmission components 31.

[0057] Of the two adjacent transmission components 31, the one closer to the stator 22 is the first transmission component, and the other is the second transmission component. The transmission link 311 of the first transmission component is the first link, and the transmission link 311 of the second transmission component is the second link. The input end 3111 of the second link is hinged to the output end 3112 of the first link, and the output end 3112 of the second link is hinged to the adapter 1. The input end 3111 of the first link is connected to the mover 21.

[0058] It should be understood that when the number of transmission components 31 is three or more, the input end 3111 of the transmission link 311 closest to the stator 22 among the multiple transmission components 31 is connected to the mover 21, and its output end 3112 is connected to the input end 3111 of its adjacent transmission link 311; the output end 3112 of the transmission link 311 furthest from the stator 22 among the multiple transmission components 31 is connected to the adapter 1, and its input end 3111 is connected to the output end 3112 of its adjacent transmission link 311.

[0059] Connecting the input end 3111 of the adjacent second link to the output end 3112 of the first link allows the output end 3112 of the first link to amplify the output force of the mover 21, and the second link to amplify the output force of the output end 3112 of the first link. In other words, the amplification factor of the output force of the mover 21 by the amplification mechanism 3 is the product of the amplification factors of multiple transmission components 31. This allows the amplification mechanism 3 to amplify the output force of the mover 21 by multiple times, further amplifying the output force of the mover 21. This enables the linear motor 2 with a smaller output power to meet the output requirements of the power output assembly 10, further expanding the range of linear motors 2 that can be selected for the power output assembly 10, allowing the power output assembly 10 to use linear motors 2 with smaller specifications, and further reducing the production cost of the power output assembly 10.

[0060] Reference Figure 2 and Figure 3 In some optional embodiments of the present invention, the extension direction of the first link intersects the extension direction of the second link, and the output end 3112 of the second link is located on the side of the input end 3111 of the second link close to the input end 3111 of the first link. This allows the first link and the second link to be arranged in a generally ">" shape, making the radial dimension of the amplification mechanism 3 of the mover 21 smaller, and making the overall structure of the power output assembly 10 more compact.

[0061] Reference Figure 2 and Figure 3 In some optional embodiments of the present invention, the amplification mechanism 3 further includes a movable link 32, one end of which is hinged to the output end 3112 of the first link, and the other end of which is hinged to the input end 3111 of the second link. The extension direction of the movable link 32 intersects the extension direction of the first link and the extension direction of the second link. This allows the amplification mechanism 3 to form a multi-link mechanism, increasing the degree of freedom of the amplification mechanism 3, reducing the risk of self-locking of the amplification mechanism 3, improving the reliability of the amplification mechanism 3, and enabling the linear motor 2 to reliably drive the transition part 1 through the amplification mechanism 3, thereby improving the reliability of the power output assembly 10.

[0062] Reference Figures 1-3 According to a second aspect of the present invention, an active suspension system includes: a power output assembly 10 according to the first aspect of the present invention described above.

[0063] According to the active suspension system of the present invention, the overall structure of the power output assembly 10 is relatively simple and easy to assemble. It can improve the response speed of the active suspension system, enable the active suspension system to have a larger output force, reduce the production cost of the active suspension system, reduce the overall weight of the active suspension system, and improve the overall performance of the vehicle 100.

[0064] Reference Figures 1-3 According to a third aspect embodiment of the present invention, a vehicle 100 includes a body structure 40 and a power output assembly 10; the power output assembly 10 is the same as the power output assembly 10 described in the first aspect embodiment of the present invention, and the adapter 1 of the active suspension system is connected to the body structure 40. For example, the vehicle 100 may be an automobile.

[0065] According to the present invention, the vehicle 100, through the above-described active suspension system, can improve the response speed of the active suspension system, effectively control the stability of the vehicle body and the movement of the wheels, improve the comfort and handling of the vehicle 100, meet more driving conditions, reduce the overall weight of the vehicle 100, and improve the overall performance of the vehicle 100.
