Specifically, as shown in fig. 8, the primary structure 110 includes at least three fixing faces 114, and the fixing faces 114 are configured as a planar structure. At least three fixation surfaces 114 are connected to each other in sequence. An included angle is formed between adjacent fixation surfaces 114.

Thus, at least three of the fixation surfaces 114 define a polyhedral structure.

The primary structure 110 is constructed as a single piece. The primary structure 110 is constructed as a cuboid structure, and has simple and reliable structure, and reduces the processing difficulty. The longitudinal cross-sectional shape of the primary structure 110 is quadrilateral. Preferably, the longitudinal cross-sectional shape of the primary structure 110 is square. In the present embodiment, the "longitudinal section" is perpendicular to the first direction D1. The primary structure 110 includes four fixation surfaces 114. Four fixing surfaces 114 are connected to each other in pairs. The angle between adjacent fixation surfaces 114 is a right angle. The primary structure 110 may include more faceted prism structures. Of course, the primary structure 110 may also be configured as a triangular prism structure, a pentagonal prism structure, a hexagonal prism structure, or a more faceted prism structure, which is not intended to be limiting in this embodiment. In this way, difficulties in the fabrication of the primary structure 110 are avoided.

The fixing surface 114 is provided with a plurality of first protruding portions 113, and the plurality of first protruding portions 113 are disposed at intervals along the first direction D1. The first protruding portion 113 protrudes from the fixing surface 114. A first groove 111 is formed between adjacent first protrusions 113. In order to further increase the magnitude of the electromagnetic force generated by the primary structure 110, the fixing surface 114 is provided with a plurality of first grooves 111, and the plurality of first grooves 111 are spaced apart along the first direction D1.

The disc coil 112 is located in the first recess 111. The disc coil 112 is disposed around the first protrusion 113. The circumferential centerline of the disc coil 112 is perpendicular to the fixed surface 114. The surrounding center line of the disc coil 112 is parallel to the center axis of the primary structure 110. The first direction D1 intersects the surrounding center line. The disc coil 112 forms a racetrack disc coil structure. Thereby, the disc coil 112 forms a closed structure.

According to the primary structure 110 of the present application, the primary structure 110 includes at least three fixing surfaces 114, at least two disc coils 112, and an insulating member 193, the fixing surfaces 114 are provided with a plurality of first protrusions 113, the plurality of first protrusions 113 are disposed at intervals along a first direction, the disc coils 112 are disposed around the first protrusions 113, and the insulating member 193 is located between the two disc coils 112. Therefore, the structure is simple and reliable, the processing difficulty is reduced, the disc coil is arranged around the first protruding part, and the power density of electromagnetic force generated by electrifying the disc coil is high.

Fig. 1 and 2 show a motor of a preferred embodiment provided herein, the motor comprising a primary structure 110 and a secondary structure 130, the primary structure 110 being made of a magnetically conductive structure. The primary structure 110 is a stator core. The length direction of the primary structure 110 is parallel to the first direction D1. The length direction of the secondary structure 130 is parallel to the first direction D1. The secondary structure 130 is made of a magnetically conductive structure. The secondary structure 130 is a mover core. The primary structure 110 and the secondary structure 130 are oppositely disposed in a direction perpendicular to the first direction D1. Secondary structure 130 is spaced apart from primary structure 110. A constant air gap exists between the secondary structure 130 and the primary structure 110.

The primary structure 110 comprises at least two disc coils 112, the disc coils 112 being arranged to the primary structure 110. The secondary structure 130 is disposed opposite the disc coil 112. The power supply provides power to the disc coil 112. The power supply can be a plurality of power supply devices such as a battery, external alternating current or a generator. After the disc coil 112 is energized, the disc coil 112 generates a magnetic field, the direction of which intersects the primary structure 110, and the direction of which also intersects the secondary structure 130, so that the secondary structure 130 and the primary structure 110 can relatively move in the first direction D1. In particular, the primary structure 110 is fixed, and electromagnetic force can act sufficiently on the secondary structure 130 such that the secondary structure 130 can move in the first direction D1. Of course, the secondary structure 130 can be fixed, and the electromagnetic force of the disc coil 112 can also act on the primary structure 110 so that the primary structure 110 can move in the first direction D1.

As an alternative embodiment, the primary structure 110 has a dimension in the first direction D1 that is greater than the dimension of the secondary structure 130 in the first direction D1. In this way, material of the secondary structure 130 can be saved, reducing costs. As another alternative embodiment, the length of the primary structure 110 in the first direction D1 is equal to the length of the secondary structure 130 in the first direction D1. In this way, the primary structure 110 and the secondary structure 130 can be fully utilized, so that the electromagnetic force can be fully generated by the 112 located on the primary structure 110, and the electromagnetic force can be fully applied to the secondary structure 130, so that the displacement of the secondary structure 130 moving along the first direction D1 is larger.

In order to ensure that the electromagnetic force generated by the disc coil 112 can drive the secondary structure 130 to move with maximum efficiency, the primary structure 110 is constructed as a polyhedral structure, and the structure is simple and reliable, so that the processing difficulty is reduced. Specifically, as shown in fig. 8, the primary structure 110 includes at least three fixing faces 114, and the fixing faces 114 are configured as a planar structure. At least three fixation surfaces 114 are connected to each other in sequence. An included angle is formed between adjacent fixation surfaces 114. It will be appreciated that the sum of the angles formed between all of the fixing surfaces should be 360. One side of one fixing surface 114 is connected to one side of an adjacent other fixing surface 114, the other side of the other fixing surface 114 is connected to one side of a further fixing surface 114, and the other side of the further fixing surface 114 is connected to the other side of the one fixing surface 114. Thus, at least three of the fixation surfaces 114 define a polyhedral structure.

The fixing surface 114 is provided with a plurality of first protruding portions 113, and the plurality of first protruding portions 113 are disposed at intervals along the first direction D1. The first protruding portion 113 protrudes from the fixing surface 114. The first protrusion 113 protrudes from the fixing surface 114 toward the secondary structure 130.

A first groove 111 is formed between adjacent first protrusions 113. The opening direction of the first recess 111 is towards the secondary structure 130. In order to further increase the magnitude of the electromagnetic force generated by the primary structure 110, the fixing surface 114 is provided with a plurality of first grooves 111, and the plurality of first grooves 111 are spaced apart along the first direction D1.

The disc coil 112 is located in the first recess 111. The disc coil 112 is disposed around the first protrusion 113. The circumferential centerline of the disc coil 112 is perpendicular to the fixed surface 114. The surrounding center line of the disc coil 112 is parallel to the center axis of the primary structure 110. The first direction D1 intersects the surrounding center line. The disc coil 112 forms a racetrack disc coil structure. Thereby, the disk coil 112 forms a closed structure, and electromagnetic force generated by the disk coil 112 can drive the secondary structure 130 to move in the first direction D1. The disc coil 112, when energized, generates a magnetic field and makes the primary structure 110 magnetic. After the disc coil 112 is energized, a strong electromagnetic force can be generated, so as to drive the secondary structure 130 to move.

A respective portion of two disc coils 112 is provided in the first groove 111. A part of the disc coil 112 is disposed in the first groove 111, and another part of the disc coil 112 protrudes from the first groove 111. A disc coil 112 is provided in each of the plurality of first grooves 111, and the disc coil 112 in each of the plurality of first grooves 111 is capable of generating electromagnetic force. The disc coils 112 in each of the first grooves 111 can form independent electronic units, thereby enabling the disc coils 112 in the plurality of first grooves 111 to form a plurality of independent electronic units corresponding to the secondary structure 130. The electromagnetic forces generated by the plurality of disc coils 112 can collectively act on the secondary structure 130 such that the secondary structure 130 can move. In order to avoid short-circuiting of adjacent two disc coils 112 in the first groove 111, an insulating member is provided between respective portions of the two disc coils 112 located in the same first groove 111.

As shown in fig. 6 and 7, the corners 115 of the disc coils 112 in the plurality of first grooves 111 each have an inlet end and an outlet end, and the inlet end of one disc coil 112 and the outlet end of the other disc coil 112 are connected by an electric wire 119 so that the two disc coils 112 are connected in series. Further, the disc coils 112 in the plurality of first grooves 111 of the same fixing face 114 are connected in series. The disc coils 112 in the plurality of first grooves 111 of the same fixing surface 114 are connected in series to form one winding. The disc coil 112 can greatly reduce the winding head and improve the utilization of the winding. For example, a plurality of disc coils 112 of a stationary face 114 may form a phase winding. A plurality of windings of a certain phase may be connected in parallel to form a multi-phase winding 121. Alternatively, multiple disc coils 112 of a stationary face 114 may also form a three-phase winding 120.

For example, a plurality of disc coils 112 of a portion of the same stationary surface 114 are connected in series to form a first winding. A plurality of disc coils 112 of another portion of the same stationary surface 114 are connected in series to form a second winding. A plurality of disc coils 112 of a further portion of the same stationary surface 114 are connected in series to form a third winding. The three windings are connected in parallel to form a three-phase winding 120. Of course, a greater number of disc coils 112 of the same stationary face 114 may form more phase windings that are connected in parallel, thereby forming a multi-phase winding 121. Thus, each stationary surface 114 may be formed with an independently configured three-phase winding 120 or multi-phase winding that may be combined with its adjacent secondary structure 130 to form a plurality of switched flux linear motor units. Thus, the electromagnetic force output mode of the active suspension 100 can be made more diverse, and the fault tolerance of the system is increased.

Further, to correspond to the primary structure 110, the motor comprises at least three secondary structures 130, the at least three secondary structures 130 being disposed opposite the at least three stationary surfaces 114, respectively. A secondary structure 130 corresponds to a fixed surface 114. At least three secondary structures 130 are spaced apart from one another. The angle formed between adjacent secondary structures 130 is equal to the angle formed between adjacent fixation surfaces 114. The three-phase windings 120 or the multi-phase windings independently formed on each of the stationary surfaces 114 may together form a plurality of switched flux linear motor units. Therefore, the electromagnetic force output modes of the motor can be more various, and the fault tolerance of the system is improved.

The length direction of the secondary structure 130 is parallel to the first direction D1. In this way, difficulties in making the secondary structure 130 are avoided. As an alternative embodiment, the primary structure 110 has a dimension in the first direction D1 that is greater than the dimension of the secondary structure 130. In this way, material of the secondary structure 130 can be saved, reducing costs. As another alternative embodiment, the dimension of the primary structure 110 in the first direction D1 is equal to the dimension of the secondary structure 130. In this way, the primary structure 110 and the secondary structure 130 can be fully utilized, so that the disk coil 112 located on the primary structure 110 can fully generate electromagnetic force, which can fully act on the secondary structure 130, so that the displacement of the secondary structure 130 moving in the first direction D1 is large.

In order to ensure the stability of the magnetic field generated by the primary structure 110, the disk coils 112 of the at least three fastening surfaces 114 are not connected to each other. The disc coil 112 of the first stationary surface generates a first magnetic field, the disc coil 112 of the second stationary surface generates a second magnetic field, and the disc coil 112 of the nth stationary surface generates an nth magnetic field. N is an integer greater than two.

The disc coil 112 of the first fixing surface and the disc coil 112 of the second fixing surface are not connected to each other. When the disc coil 112 of the first fixing surface is damaged and cannot generate a magnetic field, the disc coil 112 of the second fixing surface is in a normal power-on state and can still generate a second magnetic field. Likewise, the disc coil 112 of the first fixing surface and the disc coil 112 of the nth fixing surface are not connected to each other. When the disc coil 112 of the first fixing surface is damaged and cannot generate a magnetic field, the disc coil 112 of the nth fixing surface can still generate the nth magnetic field when in a normal power-on state. The disc coil 112 of the second fixing surface and the disc coil 112 of the nth fixing surface are not connected to each other. When the disc coil 112 of the second fixing surface is damaged and cannot generate a magnetic field, the disc coil 112 of the nth fixing surface can still generate the nth magnetic field when in a normal power-on state. Thereby, the reliability of the primary structure 110 is improved.

In order to be able to fully utilize the electromagnetic force of the disc coil 112, the cross-sectional shape of the first protrusion 113 is configured in a rectangular shape. In the present embodiment, the "cross section" is parallel to the first direction D1. As shown in fig. 8, the first protrusion 113 includes a first side surface 122 and a second side surface 123, and the first side surface 122 and the second side surface 123 are vertically connected. The disc coil 112 is circumferentially disposed to the first side surface 122 and the second side surface 123. The two first side surfaces 122 are oppositely arranged along the first direction D1. The two second side surfaces 123 are oppositely arranged in a direction perpendicular to the first direction D1. The first side surface 122 is perpendicular to the first direction D1. The second side surface 123 is parallel to the first direction D1. The length of the first side surface 122 is greater than the length of the second side surface 123. In this way, the disc coil 112 is guaranteed to have a large electromagnetic force along the first direction D1, and thus the secondary structure 130 is driven to be movable along the first direction D1.

Further, the cross-sectional shape of the disc coil 112 is configured in a zigzag shape. The disc coil 112 includes first line segments 124, with the two first line segments 124 being spaced apart along the first direction D1. The length direction of the first line segment 124 is perpendicular to the first direction D1. The two first line segments 124 of the same disc coil 112 are spaced apart along the first direction D1, and one first protrusion 113 is disposed between the two first line segments 124 along the first direction D1. Further, two first wire segments 124 of the same disc coil 112 may be located in two adjacent first grooves 111, respectively. One first line segment 124 of the same disc coil 112 is located in one first groove 111, and the other first line segment 124 of the same disc coil 112 is located in the other first groove 111. In this way, it is ensured that the two first line segments 124 are able to generate a magnetic field force in the first direction D1 sufficiently to drive the secondary structure 130 to be movable in the first direction D1.

The disc coil 112 further includes a second wire segment 125, and the first wire segment 124 and the second wire segment 125 are vertically connected. The two second line segments 125 are oppositely arranged along a direction perpendicular to the first direction D1. The second line segment 125 is located between the two first line segments 124 along the first direction D1. The second line segment 125 is parallel to the first direction D1. Thus, the first line segment 124 of the primary structure 110 is capable of generating electromagnetic force along the first direction D1, and the direction of the electromagnetic force generated by the first line segment 124 is parallel to the first direction D1. The second line segment 125 provides a path for the current to communicate.

The length of the first line segment 124 is greater than the length of the second line segment 125. The first wire segment 124 is disposed outside the first side surface 122. The first wire segment 124 is attached to the first side surface 122. The second line segment 125 is disposed outside the second side surface 123. The second line segment 125 is attached to the second side surface 123. In this way, the disc coil 112 is guaranteed to have a large electromagnetic force along the first direction D1, and thus the secondary structure 130 is driven to be movable along the first direction D1.

Two second line segments 125 of the same disc coil 112 are arranged at intervals along the direction perpendicular to the first direction D1, and one first protruding portion 113 is arranged between the two second line segments 125 along the length direction of the first line segment 124. The second line segments are respectively located at two ends of the first protruding portion 113 along the length direction of the first line segment 124. The first groove 111 and the first protrusion 113 are flush along the length of the first line segment 124. In order to ensure that the disc coil 112 can be disposed around the first protrusion 113, the second line segment 125 protrudes from the first groove 111 along the length direction of the first line segment 124. The disc coil 112 is wound on the first protrusion 113. The second line segment 125 is located outside the second side surface 123 along the length direction of the first line segment 124. The second wire segment 125 does not cut the magnetic field force generated by the disc coil 112, i.e., the second wire segment 125 does not affect the movement of the secondary structure 130 in the first direction D1.

Another first projection 113 is provided between the adjacent two disc coils 112. In particular, the further first projection 113 is located between one first wire section 124 of one disc coil 112 and one first wire section 124 of the further disc coil 112. The second line segments 125 of adjacent two disc coils 112 are spaced apart along the first direction D1. Adjacent two disc coils 112 are not in direct contact. In this way, the energization of the adjacent two disc coils 112 to each other does not affect each other.

In the embodiment shown in fig. 3, the same first recess 111 is provided with respective first wire segments 124 of two disc windings 112. A first wire segment 124 of one disc coil 112 and a first wire segment 124 of another disc coil 112 are both located in the same first recess 111. To avoid shorting of the two disc coils 112, an insulating member is located between the respective first wire segments 124 of the two disc coils 112 in the first direction D1. The insulating member is located between one first wire section 124 of one disc coil 112 and one first wire section 124 of the other disc coil 112 in the first direction D1.

In an embodiment, not shown, at least two disc coils 112 are arranged side by side in a direction perpendicular to the first direction D1. At least two disc coils 112 may be stacked together. For example, at least two disc coils 112 are arranged side by side in the thickness direction of the disc coils 112. The thickness direction of the disc coil 112 is perpendicular to the first direction D1. The insulating member is located between the adjacent disc coils 112 in a direction perpendicular to the first direction D1. Thereby, the occurrence of a short circuit in at least two disc coils 112 is avoided.

In order to avoid short-circuit influence caused by direct contact of the disc coils 112 of the adjacent fixing surfaces 114, the first protrusions 113 of the adjacent fixing surfaces 114 are spaced apart from each other. A gap is formed between the first protrusions 113 of the adjacent fixing surfaces 114. The gap is a heat dissipation channel of the disc coil 112, and ensures that the disc coils 112 of adjacent fixing surfaces 114 are spaced apart, and also avoids temperature and electromagnetic interference during operation. Preferably, a gap is also located between the first protrusion 113 of one fixation surface 114 and the disc coil 112 of the adjacent other fixation surface 114. Thereby, the first protrusion 113 of one fixing surface 114 and the disk coil 112 of the other fixing surface 114 are ensured to be spaced apart from each other, avoiding mutual influence. For example, a gap is located between the disc coil of the first fixing surface and the first protrusion of the second fixing surface. The gap can extend in a first direction D1 to form a chamber. The chamber is constructed in a rectangular parallelepiped structure. Therefore, the disc-type coils of the first fixing surface and the first protruding parts of the second fixing surface are ensured to be spaced, and interference between the disc-type coils of the adjacent fixing surfaces and the first protruding parts is avoided.

Fig. 4 and 5 show the structure of the secondary structure 130, and the secondary structure 130 includes a plurality of second protrusions 132, the second protrusions 132 protruding toward the primary structure 110 in a direction perpendicular to the first direction D1. The plurality of second protrusions 132 are arranged at intervals along the first direction D1. A second groove 131 is formed between adjacent second protrusions 132. The second grooves 131 are open toward the primary structure 110. The second protrusion 132 and the second groove 131 together form an uneven structure. The magnetic field generated by the disc coil 112 after being energized acts on the rugged structure of the secondary structure 130, so that the electromagnetic force generated by the disc coil 112 after being energized can drive the secondary structure 130 to move.

The second protrusion 132 is located between the two second grooves 131 along the first direction D1. The projection of the first groove 111 in a direction perpendicular to the first direction D1 coincides at least partially with the projection of the second groove 131. Preferably, the disc coil 112 is disposed at least partially opposite the second recess 131. In this way, it is ensured that the electromagnetic force generated by the energizing of the disc coil 112 acts on the second recess 131, and the magnetic field lines of the magnetic field generated by the disc coil 112 cut with the second recess 131, thereby driving the secondary structure 130 to move in the first direction D1. The projection of the disc coil 112 in a direction perpendicular to the first direction D1 coincides at least partially with the projection of the second recess 131. The projection of the disc coil 112 along the length of the first wire section 124 coincides at least partially with the projection of the second groove 131.

To secure the at least three secondary structures 130, the motor further includes a support member 160 configured as a hollow polyhedral structure. The support member 160 can ensure that the secondary structure 130 is opposite the disc coil 112. The primary structure 110 and the secondary structure 130 are positioned in the support member 160 such that the secondary structure 130 can be driven to move by electromagnetic force generated upon energization of the disc coil 112 in the support member 160. And, the secondary structure 130 is connected to the support member 160. The secondary structure 130 moves along the first direction D1 to drive the support member 160 to move along the first direction D1.

Specifically, the support member 160 includes a main body 161, and the main body 161 is configured in a sleeve structure. The body 161 is for housing the primary structure 110 and the secondary structure 130. The body 161 includes a body hole 164, and a length direction of the body hole 164 is parallel to the first direction D1. The longitudinal cross-sectional shape of the body hole 164 is quadrangular. The body aperture 164 has the primary structure 110 and the secondary structure 130 disposed therein. The shape of the body aperture 164 matches the shape of the primary structure 110.

The body 161 may be constructed in a polyhedral sleeve structure. The body 161 includes at least three inner surfaces 169, the at least three inner surfaces 169 being connected to one another in sequence. An included angle is formed between adjacent inner surfaces 169. It will be appreciated that the sum of the angles formed between all of the inner surfaces 169 should be 360. One side of one inner surface 169 is connected to one side of an adjacent other inner surface 169, the other side of the other inner surface 169 is connected to one side of yet another inner surface 169, and the other side of the yet another inner surface 169 is connected to the other side of the one inner surface 169. Thus, at least three of the inner surfaces 169 define a polyhedral structure.

The body 161 is constructed as a single piece. The main body 161 is constructed into a cuboid sleeve structure, so that the structure is simple and reliable, and the processing difficulty is reduced. At least three inner surfaces 169 are respectively opposite at least three fixation surfaces 114. In the embodiment shown in fig. 4, the body 161 is constructed in a tetrahedral sleeve structure. The longitudinal cross-sectional shape of the main body 161 is a four-sided ring shape. Preferably, the longitudinal cross-sectional shape of the body 161 is square ring shape. The body 161 includes four inner surfaces 169. The four inner surfaces 169 are connected to each other. The angle between adjacent inner surfaces 169 is a right angle. The four inner surfaces 169 are respectively opposite to the four fixing surfaces 114. The body 161 may include more faceted prismatic structures to match the shape of the primary structure 110. For example, the body 161 may be configured as a triangular prism structure, a pentagonal prism structure, a hexagonal prism structure, or a more faceted prism structure according to the shape of the primary structure 110, which is not intended to be limiting in this embodiment.

The main body 161 is connected with the secondary structure 130. The main body 161 and the secondary structure 130 are fixedly connected. The main body 161 and the sub-structure 130 are fixedly coupled together by bonding or welding. The secondary structure 130 moves to move the main body 161 along the first direction D1. As shown in connection with fig. 4, the inner surface 169 faces the primary structure 110. The inner surface 169 is connected to the secondary structure 130. Further, each inner surface 169 is connected to one secondary structure 130, such that at least three fixing surfaces 114 of the primary structure 110 are respectively opposite to at least three secondary structures 130, such that the disc coil 112 of each fixing surface 114 can be correspondingly applied to the corresponding secondary structure 130 after being energized, so that the secondary structure 130 moves. The at least three secondary structures 130 are capable of moving at least partially simultaneously to collectively move the support member 160.

In order to monitor the movement displacement of the secondary structure 130 in real time, the body 161 is further provided with a displacement sensor 166. The displacement sensor 166 is located at a corner 165 of the body 161. The displacement sensor 166 is located at an edge of the body 161. The corners 165 of the body 161 are provided with notches 167. Notch 167 is recessed inwardly from the outer surface of body 161. The displacement sensor 166 is located in the notch 167. In this way, temperature and electromagnetic interference caused by the displacement sensor 166 when the disc coil 112 is energized are avoided, and the space utilization of the support member 160 is improved.

The support member 160 further includes a guide part 163, and the guide part 163 is connected to the body 161. The guide 163 is constructed in a rod-like structure. The guide 163 is disposed in the body hole 164. The guide 163 may be connected to the bottom of the inside of the body 161 in the first direction D1. The guide 163 and the body 161 may be coupled together by welding or integrally molding. The body 161 can move to drive the guide 163 to move.

As shown in fig. 3, the primary structure 110 includes a guide hole 118, and an axial direction of the guide hole 118 is parallel to the first direction D1. The guide 163 is inserted into the primary structure 110. In particular, the guide 163 is inserted into the guide hole 118. The guide 163 is movable in a first direction D1 relative to the primary structure 110. The primary structure 110 acts as a constraint to the guide 163 to achieve radial positioning. Therefore, the guide part 163 can guide the movement of the secondary structure 130, can ensure that the secondary structure 130 moves linearly along the first direction D1, and plays a role in guiding and limiting, so as to prevent the primary structure 110 and the secondary structure 130 from being contacted by the radial unbalanced magnetic tension when the primary structure 110 and the secondary structure 130 are eccentric, and ensure that a constant air gap exists between the primary structure 110 and the secondary structure 130 when the active suspension 100 works.

Like this, simple structure is reliable, reduces the processing degree of difficulty, and disk coil encircles first bulge setting, and disk coil circular telegram produces the electromagnetic force and can drive secondary structure and remove thereby drives the wheel and remove to reduce vibrations. Thus, the structure is simple and reliable, the processing difficulty is reduced, the disc coil 112 is arranged around the first protruding portion 113, and electromagnetic force generated by the disc coil 112 can drive the secondary structure 130 to move so as to drive the wheels to move, so that vibration of a vehicle body is reduced.

Preferably, the active suspension 100 is used in a vehicle to reduce vibration of the vehicle. The vehicle includes wheels and a body, the wheels travel on a road surface, and the active suspension 100 connects the wheels and the body. The active suspension 100 can reduce the shock transmitted from the wheel to the vehicle body. The rigidity and damping characteristics of the active suspension 100 can be dynamically adaptively adjusted according to the driving conditions of the vehicle (the movement state of the vehicle, the road surface condition, etc.), so that the active suspension 100 is in an optimal vibration reduction state.

The primary structure 110 of the motor is for attachment to the vehicle body and the secondary structure 130 is for attachment to the wheels. Specifically, one end of the primary structure 110 is for connection to a vehicle body, and one end of the secondary structure 130 is for connection to a wheel. The active suspension 100 further includes an elastic member 150, both ends of the elastic member 150 being adapted to abut the vehicle body and the wheel, respectively. In the present embodiment, "abutting" may be direct contact or indirect contact between the elastic member 150 and the vehicle body or the wheel.

The resilient member 150 is configured as a hard rigid spring. The elastic member 150 is connected to the vehicle body and the secondary structure 130 at both ends thereof in the first direction D1, respectively. In the present embodiment, the "first direction D1" is parallel to the height direction of the vehicle. The elastic member 150 is capable of elastic deformation in the first direction D1. Specifically, the elastic member 150 includes a first end 151 and a second end 152, and the first end 151 and the second end 152 are located at both ends of the elastic member 150 in the first direction D1, respectively. The first end 151 of the resilient member 150 abuts the secondary structure 130 and the second end 152 of the resilient member 150 abuts the primary structure 110.

Further, the primary structure 110 is for connection to a vehicle body, and the secondary structure 130 is for connection to a wheel. The elastic member 150 can absorb the force of impact of traveling on a bumpy road surface, thereby playing a role of shock absorption. The first end 151 of the elastic member 150 in the height direction of the vehicle abuts against the wheel through the secondary structure 130. The second end 152 of the elastic member 150 in the height direction of the vehicle abuts against the vehicle body.

As described above, the active suspension 100 further includes a support member 160, the support member 160 being connected to the secondary structure 130. The first end 151 of the resilient member 150 may abut the support member 160. The elastic member 150 abuts against the secondary structure 130 through the supporting member 160, so as to avoid the secondary structure 130 being directly connected with the elastic member 150, and avoid the structure of the secondary structure 130 from being damaged.

Secondary structure 130 is also used to connect to the wheel through support members 160. The support member 160 includes a ring portion 168, the ring portion 168 being located at the bottom of the support member 160. The ring 168 is adapted to be coupled to an axle of a wheel. The support member 160 further includes a support plate 162, and the support plate 162 protrudes from the body 161. The body 161 also includes an outer surface 170. The support plate 162 is coupled to an outer surface 170 of the body 161. In this embodiment, the "outer surface 170 of the body 161" refers to the surface of the body 161 facing away from the secondary structure 130. The support plate 162 is constructed in a flat plate structure, and has a simple structure and is convenient to process. The support plate 162 is disposed around the body 161. A portion of the body 161 is inserted into the elastic member 150. The support plate 162 is spaced apart from the end of the body 161 in the first direction D1. The support plate 162 abuts the first end 151 of the resilient member 150. The elastic force of the elastic member 150 acts on the support plate 162 to uniformly stress the support member 160.

The active suspension 100 further includes a connecting member 180, the connecting member 180 being fixedly coupled to the primary structure 110. The connection member 180 and the primary structure 110 may be connected together by welding or screwing. The primary structure 110 is for connection to a vehicle body by a connection member 180. The second end 152 of the resilient member 150 abuts the connecting member 180. In this way, the elastic member 150 abuts against the connection member 180, so as to prevent the primary structure 110 and the vehicle body from being directly connected to the elastic member 150, and prevent the structure of the primary structure 110 from being damaged to affect the electromagnetic force.

Specifically, the connecting member 180 includes an abutment plate 181, and the abutment plate 181 abuts against the second end 152 of the elastic member 150. The elastic member 150 is located between the abutment plate 181 and the support plate 162. The elastic force of the elastic member 150 acts on the abutment plate 181. The abutting plate 181 is constructed to be a flat plate structure, and has a simple structure and is convenient to process. The elastic force of the elastic member 150 acts on the abutment plate 181 to make the connecting member 180 uniformly stressed, thereby making the vehicle body uniformly stressed.

The connecting member 180 further includes an engaging portion 182, and the engaging portion 182 protrudes from the abutment plate 181 along the first direction D1. The fitting portion 182 may be configured in a rod-like structure. The axial direction of the engaging portion 182 is parallel to the first direction D1. The engaging portion 182 protrudes in the first direction D1 toward the primary structure 110. A portion of the fitting portion 182 is inserted into the elastic member 150 and passes through the elastic member 150. The engaging portion 182 is inserted into the supporting member 160 in the first direction D1. The mating portion 182 is connected with the primary structure 110 such that the primary structure 110 is connected with the connecting member 180. One end of the engaging portion 182 in the first direction D1 is for connection with a vehicle body, and the other end of the engaging portion 182 in the first direction D1 is connected with the primary structure 110. The primary structure 110 and the mating portion 182 may be joined together by bonding or welding. The primary structure 110 and the connecting member 180 are fixed together, thereby fixing the primary structure 110 to the vehicle body.

More specifically, the primary structure 110 includes a guide hole 118, and a length direction of the guide hole 118 is parallel to the first direction D1. The engaging portion 182 is inserted into the guide hole 118 in the first direction D1 and the engaging portion 182 is fixedly coupled with the primary structure 110. The mating portion 182 and the primary structure 110 may be secured together by welding, bonding, or threading. The guide hole 118 may be configured as a circular hole. The fitting portion 182 is configured in a cylindrical structure. The mating portion 182 and the guide aperture 118 are shaped to match. The fitting portion 182 and the guide hole 118 are fixed together. Of course, the guide hole 118 may be configured as a polygonal hole, the engaging portion 182 may be configured as a polyhedral structure, and the shapes of the engaging portion 182 and the guide hole 118 may be matched, which is not intended to be limiting in this embodiment.

The fitting portion 182 includes a fitting hole 183, and an axial direction of the fitting hole 183 and an axial direction of the guide hole 118 are parallel. The fitting hole 183 and the guide hole 118 are coaxially disposed. The length direction of the fitting hole 183 is parallel to the first direction D1. The guide part 163 of the support member 160 is inserted into the fitting hole 183. The fitting hole 183 is configured as a circular hole, and the guide 163 is configured as a cylindrical structure. The guide 163 is inserted into the fitting hole 183, so that the guide 163 is inserted into the primary structure 110. The guide 163 is movable in the first direction D1 with the support member 160 relative to the fitting hole 183. Thereby, the engaging hole 183 is constrained to the guide part 163, so as to realize radial positioning, ensure that the secondary structure 130 can move linearly along the first direction D1, play a role of guiding and limiting, prevent the primary structure 110 and the secondary structure 130 from being contacted by the primary structure 110 and the secondary structure 130 due to radial unbalanced magnetic tension when the primary structure 110 and the secondary structure 130 are eccentric, and ensure that a constant air gap exists between the primary structure 110 and the secondary structure 130 when the active suspension 100 works. Of course, the fitting hole 183 may be configured as a polygonal hole, the guide part 163 may be configured as a polyhedral structure, and the shapes of the guide part 163 and the fitting hole 183 are matched, which is not intended to be limiting in this embodiment.

When the vehicle runs on a bumpy road surface, the control device controls the current direction of the motor according to the data monitored by the road condition sensor. The vehicle may also reduce vibration directly by the elastic member 150 when the disc coil 112 is not energized.

For example, as shown in fig. 1, the guide 163 may closely fit the top surface of the fitting hole 183. When the vehicle is traveling on a depressed road, the control device controls the current direction of the motor to be positive, and the electromagnetic force generated by the disc coil 112 drives the secondary structure 130 to be movable in the first direction D1 in a direction away from the abutment plate 181. The secondary structure 130 can move the guide part 163 in a direction away from the abutment plate 181, so that the guide part 163 is spaced apart from the top surface of the fitting hole 183. In this way, the secondary structure 130 can drive the supporting member 160 to move downward along the height direction of the vehicle, so that the first end 151 of the elastic member 150 moves downward along the first direction D1 to be elongated, thereby driving the wheels to move downward to be fitted with the pit surface, and reducing the vibration of the vehicle body.

As shown in fig. 2, the guide 163 and the top surface of the fitting hole 183 may also be spaced apart. When the vehicle is traveling on a steep road surface, the control device controls the current direction of the motor to be reversed, and the electromagnetic force generated by the disc coil 112 drives the secondary structure 130 to be movable in the first direction D1 toward the abutment plate 181. The secondary structure 130 can drive the guide part 163 to move toward the abutment plate 181, so that the guide part 163 is attached to the top surface of the fitting hole 183.
