DETAILED DESCRIPTION

[0032] In order to make the above features and advantages of the present disclosure more obvious and easy to understand, the present disclosure will be further described in detail below in combination with the drawings and specific embodiments.

[0033] At present, during the movement of the levitation motor, the force of the magnetic part on the winding will cause the stator to have different degrees of eccentric phenomenon. This eccentric phenomenon will cause the eccentric wear of the guide mechanism to be serious when the mover moves relative to the stator through the guide mechanism of the levitation motor, thereby affecting the performance of the actuator such as the levitation motor.

[0034] To solve the above problems, as shown in FIG. 1, some embodiments of the present disclosure provide an actuator 1, which can include a first assembly 500, a second assembly 100, and a first sliding support 200. The first assembly 500 is provided with a first guide structure 510, and the second assembly 100 is provided with a second guide structure 110. When the first assembly 500 and the second assembly 100 move relative to each other, the first guide structure 510 and the second guide structure 110 guide each other.

[0035] In some embodiments, the first sliding support 200 is fixedly arranged on the first guide structure 510 and extends in the axial direction of the actuator 1. The extension range of the first sliding support 200 covers at least the relative movement range of the free end of the second guide structure 110.

[0036] In some embodiments of the present disclosure, the guide structure of the levitation motor includes at least the first assembly 500, the second assembly 100, and the first sliding support 200. One of the second assembly 100 and the first assembly 500 can move along the guide track of the other in the actuator 1 such as the levitation motor. The first assembly 500 is provided with the first guide structure 510, and the second assembly 100 is provided with the second guide structure 110, i.e., the second assembly 100 can move along the guide direction of the first guide structure 510, and the first assembly 500 can move along the guide direction of the second guide structure 110. When the first assembly 500 and the second assembly 100 move relative to each other, the first guide structure 510 and the second guide structure 110 guide each other.

[0037] In some embodiments of the present disclosure, the first sliding support 200 is fixedly arranged on the first guide structure 510 and extends in the axial direction of the actuator 1. The extension range of the first sliding support 200 covers at least the relative movement range of the free end of the second guide structure 110. It should be noted that the free end of the second guide structure 110 is the end of the second guide structure 110 that can slide in the first guide structure 510, and the end of the second assembly 100 that is not connected to the stator assembly or the rotor assembly is the free end. The relative movement range is the sliding range of the free end of the second guide structure 110 in the first guide structure 510.

[0038] For example, the first guide structure 510 is a cavity of a center rod, the second guide structure 110 is a guide rod, the center rod is connected to a vehicle body as a stator assembly, and the guide rod is connected to a vehicle wheel as a mover assembly. At this time, the relative movement range is the movement range of the guide rod in the cavity. Alternatively, the first guide structure 510 is a cavity of a center rod, the second guide structure 110 is a guide rod, the center rod is connected to a vehicle wheel as a mover assembly, and the guide rod is connected to a vehicle body as a stator assembly. At this time, the cavity of the center rod moves, and the guide rod moves relatively. The relative movement range is the movement range of the guide rod relative to the cavity during the movement of the cavity.

[0039] It can be understood that the first sliding support 200 supports the relative movement of the first guide structure 510 and the second guide structure 110. Since both ends of the second guide structure 110 are supported by the first sliding support 200, the first sliding support 200 can provide a supporting force to the second guide structure 110 during the sliding of the second guide structure 110, and the supporting force and the magnetic force of the biasing are balanced with each other, thereby reducing the wear of the second guide structure 110.

[0040] Therefore, some embodiments of the present disclosure set the first assembly 500, the second assembly 100, and the first sliding support 200, and set the first guide structure 510 on the first assembly 500 and the second guide structure 110 on the second assembly 100. In this way, when the first assembly 500 and the second assembly 100 move relatively, the first guide structure 510 and the second guide structure 110 can guide and cooperate. In addition, the first sliding support 200 is fixedly arranged on the first guide structure 510 and extends in the axial direction of the actuator 1. The extension range of the first sliding support 200 covers at least the relative movement range of the free end of the second guide structure 110. In this way, the two ends of the second guide structure 110 can be supported by the first sliding support 200, so that the two ends of the second guide structure 110 can slide under the support of the first sliding support 200, thereby enhancing the overall rigidity of the second guide structure 110. In this way, the second guide structure 110 is always in contact with the first sliding support 200 during movement, so that the eccentric wear phenomenon of the second guide structure 110 during movement is weakened, the wear amount is reduced, and the service life of the second guide structure 110 is prolonged, thereby ensuring the use performance of the actuator 1 such as a suspension motor.

[0041] In some embodiments of the present disclosure, the first sliding support 200 includes a first bearing 210, and the first bearing 210 is fixedly arranged on the first guide structure 510 and extends in the axial direction of the actuator 1.

[0042] It can be understood that the first bearing 210 is fixedly arranged on the first guide structure 510, so that the first bearing 210 can support the relative sliding of the first guide structure 510 and the second guide structure 110. As shown in FIG. 1, when the first guide structure 510 and the second guide structure 110 slide relative to each other, the first bearing 210 supports the up-and-down reciprocating movement of the first guide structure 510 and the second guide structure 110.

[0043] In addition, the first bearing 210 is a long bearing, and the extension range of the long bearing covers at least the relative movement range of the end face of the free end of the second guide structure 110.

[0044] It can be understood that the first bearing 210 can be a long bearing, and the extension range of the long bearing covers at least the relative movement range of the end face of the free end of the second guide structure 110, so that the second guide structure 110 is always in contact with the first bearing 210 when sliding, so that the first bearing 210 continuously supports the second guide structure 110 during the sliding of the second guide structure 110, thereby enhancing the rigidity of the overall structure of the second guide structure 110.

[0045] That is, as shown in FIG. 1, the first bearing 210 is arranged at the upper part in the axial direction (i.e., the Z direction) of the actuator 1. When the first guide structure 510 and the second guide structure 110 move in a direction away from each other, the first bearing 210 close to one end of the levitation motor will decrease, that is, the contact area of the first bearing 210 with the levitation motor decreases. In order to enable the first bearing 210 to always support the second guide structure 110, the contact area of the first bearing 210 at the upper end with the second guide structure 110 can be greater than zero.

[0046] In some embodiments of the present disclosure, the first sliding support 200 further comprises a second bearing 220, and the second bearing 220 is arranged in a spaced manner with the first bearing 210.

[0047] The second bearing 220 and the first bearing 210 are arranged at different positions of the first guide structure 510, and are not connected. That is, the second bearing 220 and the first bearing 210 are arranged in a spaced manner. As shown in FIG. 2, the second bearing 220 and the first bearing 210 are respectively arranged at two ends of the first guide structure 510.

[0048] In some embodiments of the present disclosure, the contact area of the second bearing 220 with the second guide structure 110 and the contact area of the first bearing 210 with the second guide structure 110 are different.

[0049] In some embodiments of the present disclosure, one side of the first sliding support 200 is in contact with the second guide structure 110, and the other side is in contact with the first guide structure 510. In this way, the first sliding support 200 can reciprocate in the range between the second guide structure 110 and the first guide structure 510, so that the stator of the levitation motor and the mover of the levitation motor can move relatively.

[0050] In some embodiments of the present disclosure, at least one of the first bearing 210 or the second bearing 220 is a sliding bearing.

[0051] In this way, at least one of the first bearing 210 or the second bearing 220 is a sliding bearing, and the second guide structure 110 is supported by the sliding bearing, so that the sliding bearing can bear the axial force generated when the second guide structure 110 moves.

[0052] In some embodiments of the present disclosure, the first assembly 500 includes a center rod, and the first guide structure 510 is arranged along the axial direction of the center rod.

[0053] It can be understood that the first assembly 500 includes a center rod, and the center rod is connected with the mover of the levitation motor, so that the stator of the levitation motor and the mover of the levitation motor can be connected with each other. The first guide structure 510 is arranged along the axial direction of the center rod, so that the center rod and the second assembly 100 can slide relative to each other.

[0054] In some embodiments of the present disclosure, the center rod is coaxial with the first guide structure 510.

[0055] In this way, by making the center rod coaxial with the first guide structure 510, the driving efficiency of the actuator 1 such as the levitation motor can be improved.

[0056] In some embodiments of the present disclosure, the first sliding support 200 is arranged between the center rod and the second assembly 100, so that the first sliding support 200 can be arranged on the inner side of the mover of the actuator 1 such as the levitation motor, so as to make the structure of the actuator 1 more compact and miniaturized.

[0057] In some embodiments of the present disclosure, the center rod is provided with a guide cavity 300, and the guide cavity 300 constitutes the first guide structure 510.

[0058] In some embodiments of the present disclosure, the center rod is provided with a guide cavity 300, that is, the center rod can be a hollow structure. The side close to the mover of the actuator 1 is the guide cavity 300, that is, the guide cavity 300 is the lower cavity of the center rod. The first sliding support 200 is arranged in the guide cavity 300, so that the first sliding support 200 can slide relative to the stator of the actuator 1. As shown in FIG. 1, the first sliding support 200 is located in the guide cavity 300 of the center rod as a whole, and the first sliding support 200 can slide in the guide cavity 300.

[0059] In some embodiments of the present disclosure, the first bearing 210 and the second bearing 220 are arranged in the guide cavity 300.

[0060] In this way, the first bearing 210 and the second bearing 220 are both located in the guide cavity 300 of the center rod, so that the first bearing 210 and the second bearing 220 can slide in the guide cavity 300.

[0061] In some embodiments of the present disclosure, the first assembly 500 further comprises a core connected to the end of the center rod away from the second assembly 100.

[0062] In this way, by connecting the core to the end of the center rod away from the second assembly 100, the core can move under the attraction of the magnetic field of the actuator 1.

[0063] In some embodiments of the present disclosure, the second assembly 100 further comprises a guide rod connected to the first guide structure 510 through the first sliding support 200.

[0064] In actual application, the second assembly 100 can be a rod-shaped part, for example, the second assembly 100 can comprise a guide rod, both ends of the guide rod being connected to the first guide structure 510 through the first sliding support 200. When the first assembly 500 and the second assembly 100 move relative to each other, the guide rod moves along the axial direction of the first bearing 210 and the second bearing 220. Since the overall rigidity of the guide rod is improved under the support of the first bearing 210 and the second bearing 220, the diameter of the guide rod can be reduced, so that the structure of the actuator 1 is more compact and miniaturized.

[0065] In some embodiments of the present disclosure, the guide rod is made of metal.

[0066] It can be understood that, due to the support of the first bearing 210 and the second bearing 220 to the guide rod, the rigidity of the guide rod is improved, so that the pressure on the guide rod is reduced. The guide rod can be made of metal. The metal can also be a lightweight metal, that is, a metal with a lower density than iron. In addition, the metal can be a single metal or an alloy. For example, aluminum alloy, titanium, titanium alloy, etc., which are not limited in the present disclosure.

[0067] In some embodiments of the present disclosure, the inner ring of the first bearing 210 and the second bearing 220 is in contact with the guide rod, and the outer ring of the first bearing 210 and the second bearing 220 is in contact with the center rod.

[0068] In practical applications, in the case of using a bearing as the first sliding support 200, the inner ring of the bearing is in contact with the guide rod, and the outer ring of the bearing is in contact with the center rod, so that the first guide structure 510 and the second guide structure 110 are coaxial. In this way, when the first guide structure 510 and the second guide structure 110 move relative to each other, they also move coaxially, improving the efficiency of the actuator 1.

[0069] In some embodiments of the present disclosure, the part of the guide rod in contact with the first guide structure 510 forms the second guide structure 110.

[0070] In some embodiments of the present disclosure, the guide rod is coaxial with the center rod. In this way, when the first guide structure 510 and the second guide structure 110 move relative to each other, they also move coaxially, improving the efficiency of the actuator 1.

[0071] In some embodiments of the present disclosure, the guide structure of the levitation motor can further include a ventilation structure 400, which is arranged in the first assembly 500 and is in communication with the first guide structure 510.

[0072] That is, the ventilation structure 400 is in communication with the guide cavity 300, so that when the second assembly 100 moves relative to the first assembly 500, the air pressure in the guide cavity 300 can be balanced with the atmospheric pressure. As shown in FIG. 1, when the second assembly 100 moves downward, the gap between the second assembly 100 and the guide cavity 300 increases, at which time air can be sucked in through the ventilation structure 400 to balance the air pressure in the guide cavity 300 with the atmospheric pressure. Conversely, when the second assembly 100 moves upward, the gap between the second assembly 100 and the guide cavity 300 decreases, at which time air can be exhausted through the ventilation structure 400 to balance the air pressure in the guide cavity 300 with the atmospheric pressure.

[0073] In some embodiments of the present disclosure, the ventilation structure 400 includes at least one ventilation hole, and each ventilation hole penetrates the first assembly 500.

[0074] In this way, for the arrangement of the ventilation structure 400, the ventilation structure 400 can include at least one ventilation hole, and each ventilation hole can penetrate the first assembly 500, thereby achieving the corresponding air pressure balancing effect.

[0075] When the at least one vent hole includes two or more vent holes, the arrangement of the vent holes can be determined according to actual conditions, which is not limited in the present disclosure. For example, when the at least one vent hole includes two vent holes, the two vent holes can be symmetrically distributed. When the at least one vent hole includes four vent holes, the four vent holes can be uniformly distributed.

[0076] The vent structure 400 can be arranged in the first assembly 500, and the vent structure 400 penetrates the first assembly 500 and communicates with the guide cavity 300. When ventilation is required, air in the guide cavity 300 penetrates the first assembly 500 and communicates with the external air through the vent structure 400.

[0077] In actual application, the actuator 1 also satisfies one of the following: the first assembly 500 is adapted to be connected with the vehicle body end, the second assembly 100 is adapted to be connected with the vehicle wheel end, or the second assembly 100 is adapted to be connected with the vehicle body end, and the first assembly 500 is adapted to be connected with the vehicle wheel end.

[0078] In summary, as shown in FIG. 1, the first sliding support 200 includes a first bearing 210 and a second bearing 220. The first bearing 210 and the second bearing 220, the first assembly 500 and the second assembly 100 constitute a guide structure of the actuator 1. When the mover of the actuator 1 moves to the lower stroke stop point of the actuator 1, the guide rod moves downward relative to the center rod, the space between the guide rod and the center rod increases, and the gas enters the guide cavity 300 through the vent structure 400, so that the air pressure in the guide cavity 300 remains stable. During the movement, the contact area between the second guide structure 110 and the upper first bearing 210 becomes smaller and smaller, but the second guide structure 110 is always in contact, thereby enhancing the rigidity of the second guide structure 110, reducing the wear of the second guide structure 110 and the first bearing 210 and the second bearing 220, and enhancing the service life of the second guide structure 110. When the mover moves to the upper stop point, the guide rod moves upward relative to the center rod, the space between the guide rod and the center rod decreases, and the air in the guide cavity 300 is discharged from the guide cavity 300 through the vent structure 400, so that the air pressure in the guide cavity 300 remains stable. During the movement, the contact area between the second guide structure 110 and the upper first bearing 210 becomes larger and larger, the rigidity of the second guide structure 110 is enhanced, and the wear of the second guide structure 110 is less.

[0079] Based on the above, as shown in FIG. 3, the actuator 1 of some embodiments of the present disclosure further comprises a housing 30, a stator 20, and a rotor 10, wherein the stator 20 is the stator part in the levitation motor assembly. The stator 20 is made of magnetically conductive material, and the stator 20 is fixed on the shell of the levitation motor assembly. Coils are wound on the stator 20, and when current passes through the coils, an alternating magnetic field is generated. The rotor 10 is the rotor part in the levitation motor assembly, made of magnetically conductive material, and the rotor 10 contains a magnetic element inside. The magnetic element can be a permanent magnet or an electromagnet, and the present disclosure does not limit it. The rotor 10 is arranged inside the housing 30. The rotor 10 moves relative to the stator 20 along the guide structure of the levitation motor, realizing up and down reciprocating motion.

[0080] As shown in FIG. 4, some embodiments of the present disclosure further provide a suspension system 2 comprising the actuator 1 as described above.

[0081] In some embodiments of the present disclosure, by taking the actuator 1 as the main body of the suspension system 2 shock absorber, the traditional hydraulic shock absorber structure is replaced. In this way, the levitation and shock absorption of the vehicle body are realized by using the principle of mutual repulsion of the same level magnetic force. In addition, the suspension system 2 becomes an active structure, so that the suspension system 2 can actively respond to the ups and downs of the road, including actively controlling roll and pitch, etc., rather than just being a passive shock absorber as in the traditional one. And, because in the process of active shock absorption, the levitation motor assembly directly does work without the oil buffer of the traditional shock absorber, the energy loss is smaller and the response speed is faster.

[0082] As shown in FIG. 5, some embodiments of the present disclosure further provide a vehicle 1000 comprising the suspension system 2 as described above.

[0083] In some embodiments of the present disclosure, the vehicle 1000 using the suspension system 2 using the above-mentioned actuator 1 can improve the chassis and driving quality of the vehicle 1000.

[0084] The vehicle 1000 of some embodiments of the present disclosure has at least the following advantages.

[0085] Significant improvement in driving stability: The shock absorber of the levitation motor can quickly and accurately adjust the height and posture of the vehicle body to respond to various complex road conditions. The ability of such active adjustment enables the vehicle 1000 to maintain better stability at high speed, on curves, or in harsh road conditions, reducing the roll and pitch of the vehicle body, and improving driving reliability and ride comfort.

[0086] Enhanced road adaptability: By adjusting the suspension system 2 in real time, the levitation motor can intelligently adjust according to different road conditions (such as potholes, bumps, slopes, etc.), so that the wheels always maintain the best ground contact state, thereby improving the passability and grip of the vehicle 1000.

[0087] Optimized handling performance: The fast response and precise control of the suspension motor make the vehicle 1000 more flexible and agile in handling. Drivers can control the steering and attitude of the vehicle 1000 more freely and enjoy a more precise handling experience.

[0088] Improved ride comfort: Since the suspension motor can actively reduce shock, reducing the impact of road bumps on the vehicle body, the ride comfort is significantly improved. Passengers in the vehicle can experience a more stable and comfortable ride, reducing fatigue during long trips.

[0089] Reduced energy consumption and noise: Compared with traditional hydraulic shock absorbers, the suspension motor has higher efficiency in energy conversion and transmission, so it can reduce energy consumption. At the same time, due to the reduction of mechanical parts friction and vibration, the noise of the vehicle 1000 during driving will also be reduced accordingly.

[0090] Improved intelligence level of the vehicle 1000: The suspension motor shock absorber, as part of the active suspension system 2 of the vehicle 1000, usually needs to be integrated with the intelligent control system of the vehicle 1000. This integration enables the vehicle 1000 to more intelligently perceive road conditions and vehicle 1000 status, thereby making more precise and efficient adjustments. This helps to improve the intelligence level of the vehicle 1000 and lays the foundation for future advanced technologies such as autonomous driving.
