[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0034] The power output assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0035] Reference Figure 1-Figure 3According to the power output assembly 10 of the first aspect of the present invention, for example, the power output assembly 10 can be applied to a vehicle 100 and used as a power output mechanism of an active suspension system. The power output assembly 10 includes: an adapter 1, a linear motor 2 and an amplification mechanism 3. The adapter 1 is suitable for connecting to the body structure 40 of the vehicle 100. The linear motor 2 includes: a mover 21 and a stator 22. The stator 22 and the adapter 1 are spaced apart along a first direction (refer to the e1 direction in the accompanying drawings). The stator 22 is used to drive the mover 21 to perform linear motion along the first direction; specifically, the stator 22 has an active hole, and the mover 21 is inserted into the active hole. 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, the transmission assembly 31 includes a transmission connecting rod 311 and a supporting shaft 312, the extension direction of the transmission connecting rod 311 intersects with the movement direction of the mover 21, the transmission connecting rod 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 the output end 3112 can be slidably connected to the adapter 1. The support shaft 312 is hinged to the transmission connecting rod 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 connecting rod 311 away from the adapter 1, that is, the transmission connecting rod 311 is placed on the support shaft 312, and the support shaft 312 can also be hinged to the support shaft 312 through the 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 connecting rod 311 is hinged with the supporting shaft 312, the supporting shaft 312 can act as a fulcrum. When the input end 3111 moves, the transmission connecting rod 311 can rotate relative to the supporting shaft 312, that is, when the input end 3111 moves away from the adapter part 1 in the first direction, the output end 3112 moves toward the adapter part 1 in the first direction; when the input end 3111 moves toward the adapter part 1 in the first direction, the output end 3112 moves away from the adapter 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 connecting rod 311, during the operation of the linear motor 2, when the mover 21 moves to the extreme position toward the adapter 1, the end of the mover 21 connected to the transmission connecting rod 311 is located on the side of the support shaft 312 away from the adapter 1 in the first direction.
[0040] When the mover 21 moves to the extreme 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, that is, the amplification mechanism 3 can amplify the force output by the mover 21.
[0041] Since the amplification mechanism 3 is a mechanical transmission, the force output by the mover 21 can be timely transmitted to the adapter 1, and then transmitted to the vehicle body structure 40 by the adapter 1, so that the advantage of the fast response of the linear motor 2 can be fully utilized to improve the response speed of the power output assembly 10. When the power output assembly 10 is arranged in an active suspension system, the active suspension system can effectively control the stability of the vehicle body and the movement of the wheels, improve the comfort and controllability of the vehicle 100, and meet more driving conditions.
[0042] At the same time, by supporting the transmission connecting rod 311 on the supporting shaft 312, the amplification mechanism 3 can use the lever principle to amplify the output force of the linear motor 2, 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 smaller output power can meet the output demand 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 specification 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 with the hydraulic active suspension system solution, the present invention does not need to set up components such as hydraulic pumps, energy storage tanks, hydraulic pipelines, etc. The overall structure is relatively simple and easy to assemble. It can improve the assembly efficiency of the active suspension system and reduce the production cost of the active suspension system. At the same time, it can reduce the overall weight of the power output assembly 10, reduce the overall weight of the active suspension system, reduce the overall weight of the vehicle 100, and realize the lightweight design of the vehicle 100.
[0044] For example, the power output assembly 10 may further include: a sealing component, the sealing component 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, so that the relative fixation between the support shaft 312 and the stator 22 can be achieved.
[0045] The telescopic member defines a sealed cavity, and the telescopic member is provided with a first opening and a second opening connected to the sealed cavity at both ends in the first direction. The stator 22 is connected and fixed to the telescopic member, the mover 21 is passed through the sealed cavity through the first opening, the amplifying mechanism 3 is arranged in the sealed cavity, and the adapter 1 is covered at the second opening. Specifically, the telescopic member can be a bellows member. In this way, the telescopic member can seal the amplifying mechanism 3, reduce the pollution of the amplifying mechanism 3 by water or dust, and effectively extend the service life of the amplifying mechanism 3. Specifically, lubricating grease can be added to the sealed cavity to lubricate the amplifying mechanism 3, more effectively extend the service life of the amplifying mechanism 3, reduce the noise generated when the amplifying mechanism 3 is working, and improve the overall performance of the power output assembly 10.
[0046] According to the power output assembly 10 of the present invention, by setting the linear motor 2 and the amplifying mechanism 3, the advantage of the fast response 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 amplifying mechanism 3 can use the lever principle to amplify the output force of the linear motor 2, so that the force output by the power output assembly 10 to the vehicle body structure 40 is larger, so that the power output assembly 10 can use a smaller power linear motor 2, thereby reducing the production cost of the power output assembly 10. Compared with the hydraulic active suspension system solution, the present invention does not need to set up components such as hydraulic pumps, energy storage tanks, and hydraulic pipelines. The overall structure is relatively simple and easy 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 amplifying mechanisms 3, and the multiple amplifying mechanisms 3 are arranged at intervals along the circumference of the mover 21. In this way, the amplifying effect of the output force of the mover 21 can be further increased, so that the linear motor 2 with a 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, so that the power output assembly 10 can select a linear motor 2 with a smaller specification, further reducing the cost of the linear motor 2, and reducing the production cost of the power output assembly 10. At the same time, multiple amplifying mechanisms 3 are arranged at intervals along the circumference of the mover 21, and each amplifying mechanism 3 applies force to the mover 21 in a different direction, so that the force on the mover 21 can be more uniform, so that the mover 21 can reliably move along the first direction, improve the stability of the operation of the mover 21, and improve the stability of the operation 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 rotation pin 13, the rotation pin 13 is passed through the hinge hole 3114, and the rotation pin 13 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 rotation 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] In this way, the transmission link 311 applies a force in a first direction to the adapter 1 while applying a force in a radial direction of the mover 21 to the adapter 1, thereby achieving follow-up between the transmission link 311 and the adapter 1, and follow-up between the transmission link 311 and the vehicle body structure 40, so that the power output assembly 10 can control the vehicle body structure 40 in multiple directions through the adapter 1, so that the active suspension system can more effectively control the stability of the vehicle body and the movement of the wheels, thereby improving the comfort and handling of the vehicle 100, thereby 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 the e2 direction in the accompanying drawings) and is suitable for connecting to the body structure 40 of the vehicle 100, the second direction intersects with the first direction, the slider 12 is arranged on the slide rail 11, and the slider 12 can slide along the extension direction of the slide rail 11, and the output end 3112 is rotatably connected to the slider 12. In this way, the output end 3112 can only apply a force in the first direction to the body structure 40 through the structure of the slider 12 and the slide rail 11, that is, the displacement of the body structure 40 is only controlled in the first direction, so that the control method of controlling the displacement of the body structure 40 in the first direction through the power output assembly 10 is relatively simple, which is convenient for researchers and developers to design the active suspension system.
[0051] Moreover, by rotationally connecting 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 with each other and locking, thereby improving the reliability of the power output assembly 10.
[0052] At the same time, in this way, the amplification effects of the output force of the mover 21 by the multiple amplification mechanisms 3 can be superimposed together, and the output force of the mover 21 can be further amplified, so that the linear motor 2 with a smaller output power can also meet the output demand of the power output assembly 10, and the range of the linear motor 2 that can be selected by the power output assembly 10 is further expanded, so that the power output assembly 10 can select a linear motor 2 with a smaller specification, further reducing the cost of the linear motor 2, and reducing the production cost of the power output assembly 10;
[0053] Furthermore, this allows the multiple amplifying mechanisms 3 to function as redundant arrangements with respect to each other, that is, when one of the amplifying mechanisms 3 fails, the remaining amplifying mechanisms 3 can still amplify the output of the linear motor 2, thereby effectively ensuring the reliability of the power output assembly 10.
[0054] Reference Figure 1 According to some embodiments of the present invention, a rotation hole 3113 is provided on the transmission connecting rod 311, and the support shaft 312 is rotatably inserted into the rotation hole 3113 relative to the transmission connecting rod 311. In this way, the risk of the transmission connecting rod 311 and the support shaft 312 being separated can be reduced, and the reliability of the amplification mechanism 3 can be improved. At the same time, in this way, the distance from the input end 3111 to the support shaft 312 can be kept constant, and the distance from the output end 3112 to the support shaft 312 can be kept constant, that is, the amplification factor of the output force of the mover 21 by the amplification mechanism 3 can be kept fixed, so that the force output by the linear motor 2 through the amplification mechanism 3 is relatively stable. At the same time, in this way, it is also convenient to calculate the displacement change of the output end 3112 in the first direction, and it is convenient to control the displacement of the adapter 1 in the first direction by controlling the displacement of the mover 21 in the first direction, that is, it is convenient to control 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 stopper 313, the stopper 313 has a stopper hole 3131 and a positioning hole 3132, the transmission connecting rod 311 is slidably inserted into the stopper hole 3131, that is, the transmission connecting rod 311 can slide in the stopper hole 3131 relative to the stopper 313, and the support shaft 312 can rotatably insert into the positioning hole 3132 relative to the stopper 313. In this way, the transmission connecting rod 311 can be fixed relative to the support shaft 312 through the stopper 313, and the sliding and rotating cooperation between the transmission connecting rod 311 and the support shaft 312 can be achieved, so that the transmission connecting rod 311 can be reliably supported on the support shaft 312, thereby 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, and the multiple transmission components 31 are arranged in sequence along the first direction. It should be noted that in the present application, multiple refers to two or more. For example, there can be two, three, four or more transmission components 31.
[0057] Of the two adjacent transmission assemblies 31, the one close to the stator 22 is the first transmission assembly, and the other is the second transmission assembly. The transmission connecting rod 311 of the first transmission assembly is the first connecting rod, and the transmission connecting rod 311 of the second transmission assembly is the second connecting rod. The input end 3111 of the second connecting rod is hinged to the output end 3112 of the first connecting rod, and the output end 3112 of the second connecting rod is hinged to the adapter 1, and the input end 3111 of the first connecting rod 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 connecting rod 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 connecting rod 311; the output end 3112 of the transmission connecting rod 311 farthest 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 connecting rod 311.
[0059] The input end 3111 of the adjacent second connecting rod is connected to the output end 3112 of the first connecting rod, so that the output end 3112 of the first connecting rod can amplify the output force of the mover 21, and the second connecting rod can amplify the output force of the output end 3112 of the first connecting rod. That is to say, the amplification factor of the output force of the mover 21 by the amplifying mechanism 3 is the product of the amplification factors of multiple transmission components 31. In this way, the output force of the mover 21 can be amplified multiple times by the amplifying mechanism 3, and the output force of the mover 21 can be further amplified, 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, so that the power output assembly 10 can select linear motors 2 with smaller specifications, and further reduce 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 connecting rod intersects with the extension direction of the second connecting rod, and the output end 3112 of the second connecting rod is located on the side of the input end 3111 of the second connecting rod close to the input end 3111 of the first connecting rod. In this way, the first connecting rod and the second connecting rod can be arranged in a substantially “>” shape, so that the size of the amplification mechanism 3 in the radial direction of the mover 21 is small, and the overall structure of the power output assembly 10 is relatively 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 the movable link 32 is hinged to the output end 3112 of the first link, the other end of the movable link 32 is hinged to the input end 3111 of the second link, the extension direction of the movable link 32 intersects with the extension direction of the first link, and the extension direction of the movable link 32 intersects with the extension direction of the second link. In this way, the amplification mechanism 3 can constitute a multi-link mechanism, improve the degree of freedom of the amplification mechanism 3, reduce the risk of self-locking of the amplification mechanism 3, improve the reliability of the amplification mechanism 3, so that the linear motor 2 can reliably drive the adapter 1 to move through the amplification mechanism 3, and improve the reliability of the power output assembly 10.
[0062] Reference Figure 1-Figure 3 The active suspension system according to the second embodiment of the present invention comprises: the power output assembly 10 according to the first embodiment of the present invention.
[0063] According to the active suspension system of the present invention, through the above-mentioned power output assembly 10, the overall structure is relatively simple and easy to assemble, which can improve the response speed of the active suspension system, so that the active suspension system has 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 Figure 1-Figure 3 The vehicle 100 according to the third embodiment of the present invention comprises: a vehicle body structure 40 and a power output assembly 10; the power output assembly 10 is the power output assembly 10 according to the first embodiment of the present invention, and the adapter 1 of the active suspension system is connected to the vehicle body structure 40. For example, the vehicle 100 may be a car.
