[0075] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings, which show representative embodiments of the present application and do not limit the present application.

[0076] Figure 1 and Figure 2 Shown is a motor according to a preferred embodiment provided by the present application. The motor includes a primary structure 110 and a secondary structure 130. The primary structure 110 is made of a magnetic 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 magnetic conductive structure. The secondary structure 130 is a mover core. The primary structure 110 and the secondary structure 130 are disposed opposite to each other in a direction perpendicular to the first direction D1. The secondary structure 130 is spaced apart from the primary structure 110. There is a constant air gap between the secondary structure 130 and the primary structure 110.

[0077] The motor further includes a disc coil 112, and the disc coil 112 is disposed on the primary structure 110. The secondary structure 130 is disposed opposite to the disc coil 112. The power supply provides electricity to the disc coil 112. The power supply can be various power supply devices such as a battery, an external alternating current, or a generator. After the disc coil 112 is energized, the disc coil 112 generates a magnetic field, and the direction of the magnetic force intersects with the primary structure 110, and the direction of the magnetic force also intersects with the secondary structure 130, so that the secondary structure 130 and the primary structure 110 can move relative to each other along the first direction D1. In particular, the primary structure 110 is fixed, and the electromagnetic force can fully act on the secondary structure 130, so that the secondary structure 130 can move along 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 along the first direction D1.

[0078] As an alternative embodiment, the size of the primary structure 110 along the first direction D1 is larger than the size of the secondary structure 130. In this way, the material of the secondary structure 130 can be saved and the cost can be reduced. As another alternative embodiment, the length of the primary structure 110 along the first direction D1 is equal to the length of the secondary structure 130. In this way, the primary structure 110 and the secondary structure 130 can be fully utilized, so that the disc coil 112 located on the primary structure 110 can fully generate electromagnetic force, and the electromagnetic force can fully act on the secondary structure 130, so that the displacement of the secondary structure 130 moving along the first direction D1 is larger.

[0079] In order to ensure that the electromagnetic force generated by the disc coil 112 can drive the secondary structure 130 to move with the highest efficiency, the primary structure 110 is configured as a polyhedron structure, which is simple and reliable in structure and reduces the processing difficulty. Specifically, as Figure 9 shown, the primary structure 110 includes a plurality of fixed surfaces 114, and the fixed surfaces 114 are configured as planar structures. The plurality of fixed surfaces 114 are sequentially connected to each other. An included angle is formed between adjacent fixed surfaces 114. It can be understood that the sum of the included angles formed between all the fixed surfaces should be 360°. One side of a fixed surface 114 is connected to one side of an adjacent fixed surface 114, the other side of the other fixed surface 114 is connected to one side of another fixed surface 114, and the other side of the other fixed surface 114 is connected to the other side of the one fixed surface 114. In this way, the plurality of fixed surfaces 114 enclose a polyhedron structure.

[0080] The primary structure 110 is configured as a single piece. The primary structure 110 is configured as a cuboid structure, with a simple and reliable structure, reducing the processing difficulty. The longitudinal cross-sectional shape of the primary structure 110 is a quadrilateral. Preferably, the longitudinal cross-sectional shape of the primary structure 110 is a square. In the present embodiment, the "longitudinal cross-section" is perpendicular to the first direction D1. The primary structure 110 includes four fixing surfaces 114. The four fixing surfaces 114 are pairwise connected to each other. The included angle between adjacent fixing surfaces 114 is a right angle. The primary structure 110 may include a prismatic structure with more faces. 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 prismatic structure with more faces, and the present embodiment does not intend to limit this. In this way, the difficulty of manufacturing the primary structure 110 is avoided.

[0081] The primary structure 110 further includes a plurality of first protrusions 113, and the plurality of first protrusions 113 are arranged at intervals along the first direction D1. The first protrusions 113 protrude from the fixing surfaces 114. The first protrusions 113 protrude from the fixing surfaces 114 in the direction towards the secondary structure 130. The disk coil 112 is arranged around the first protrusions 113. The circumferential center line of the disk coil 112 is perpendicular to the fixing surfaces 114. The disk coil 112 forms a racetrack-shaped coil structure. Thus, the disk coil 112 forms a closed structure, and the electromagnetic force generated by the disk coil 112 can drive the secondary structure 130 to move along the first direction D1. After the disk coil 112 is energized, it generates a magnetic field and makes the primary structure 110 magnetic. After the disk coil 112 is energized, it can generate a strong electromagnetic force, thereby driving the secondary structure 130 to move.

[0082] According to the motor of the present application, the motor includes a primary structure 110, a disk coil 112, and a secondary structure 130. The primary structure 110 includes a plurality of fixing surfaces 114, and the fixing surfaces 114 are provided with a plurality of first protrusions 113. The first protrusions protrude from the fixing surfaces, and the plurality of first protrusions 113 are arranged at intervals along the first direction. The disk coil 112 is arranged around the first protrusions 113. The circumferential center line of the disk coil 112 is perpendicular to the fixing surfaces 114. The first direction intersects with the circumferential center line. The secondary structure 130 is spaced apart from the primary structure 110, and the secondary structure 130 is disposed opposite to the disk coil 112. The disk coil 112 is energized to generate a magnetic field so that the secondary structure 130 and the primary structure 110 can move relative to each other along the first direction. In this way, the structure is simple and reliable, reducing the processing difficulty. The disk coil 112 is arranged around the first protrusions 113, and the electromagnetic force generated by the disk coil 112 can drive the secondary structure 130 to move, thereby driving the wheels to move, so as to reduce the vibration of the vehicle body.

[0083] The primary structure 110 is also formed with a first groove 111, and the opening direction of the first groove 111 faces the secondary structure 130. The first groove 111 is formed between adjacent first protrusions. In order to further increase the magnitude of the electromagnetic force generated by the primary structure 110, a plurality of first grooves 111 are provided on the fixing surface 114, and the plurality of first grooves 111 are arranged at intervals along the first direction D1.

[0084] A part of the disk coil 112 is disposed in the first groove 111, and the other part of the disk coil 112 protrudes from the first groove 111. The disk coil 112 is disposed in each of the plurality of first grooves 111, and the disk coils 112 in the plurality of first grooves 111 can all generate electromagnetic force. The disk coil 112 in each first groove 111 can form an independent electronic unit, so that the windings formed by the disk coils 112 in the plurality of first grooves 111 corresponding to the secondary structure 130 can form a plurality of independent electronic units. The electromagnetic forces generated by the plurality of first line segments 124 can act on the secondary structure 130 together, so that the secondary structure 130 can move.

[0085] As Figure 7 and Figure 8 shown, the corners 115 of the disk coils 112 in the plurality of first grooves 111 all have an incoming line end and an outgoing line end, and the incoming line end of one disk coil 112 and the outgoing line end of another disk coil 112 are connected by a wire 119 so that the two disk coils 112 are connected in series. Further, the disk coils 112 in the plurality of first grooves 111 on the same fixing surface 114 are connected in series. The disk coils 112 in the plurality of first grooves 111 on the same fixing surface 114 are connected in series to form a winding. For example, the plurality of disk coils 112 on one fixing surface 114 can form a certain phase winding. A plurality of certain phase windings are connected in parallel to form a multi-phase winding 121. Or, the plurality of disk coils 112 on one fixing surface 114 can also form a three-phase winding 120.

[0086] For example, the plurality of disk coils 112 in a part of the same fixing surface 114 are connected in series to form a first winding. The plurality of disk coils 112 in another part of the same fixing surface 114 are connected in series to form a second winding. The plurality of disk coils 112 in still another part of the same fixing 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 larger number of disk coils 112 on the same fixing surface 114 can form windings of more phases, and the windings of more phases are connected in parallel, thereby forming a multi-phase winding 121. In this way, the three-phase winding 120 or the multi-phase winding independently formed on each fixing surface 114 can jointly form a plurality of switched reluctance linear motor units with its adjacent secondary structure 130. Thus, the electromagnetic force output mode of the active suspension 100 can be made more diverse, increasing the fault tolerance of the system.

[0087] To ensure the stability of the magnetic field generated by the primary structure 110, the disk coils 112 on multiple fixing surfaces 114 are not connected to each other. The disk coil 112 on the first fixing surface generates a first magnetic field, the disk coil 112 on the second fixing surface generates a second magnetic field, and the disk coil 112 on the Nth fixing surface generates an Nth magnetic field. N is an integer greater than two.

[0088] The disk coil 112 on the first fixing surface and the disk coil 112 on the second fixing surface are not connected to each other. When the disk coil 112 on the first fixing surface is damaged and unable to generate a magnetic field, the disk coil 112 on the second fixing surface is in a normal energized state and can still generate a second magnetic field. Similarly, the disk coil 112 on the first fixing surface and the disk coil 112 on the Nth fixing surface are not connected to each other. When the disk coil 112 on the first fixing surface is damaged and unable to generate a magnetic field, the disk coil 112 on the Nth fixing surface is in a normal energized state and can still generate an Nth magnetic field. The disk coil 112 on the second fixing surface and the disk coil 112 on the Nth fixing surface are not connected to each other. When the disk coil 112 on the second fixing surface is damaged and unable to generate a magnetic field, the disk coil 112 on the Nth fixing surface is in a normal energized state and can still generate an Nth magnetic field. Thus, the reliability of the primary structure 110 is improved.

[0089] Optionally, to increase the electromagnetic force, the motor further includes a magnetic member 117. The first protrusion 113 is provided with a magnetic groove 116, and the magnetic member 117 is disposed in the magnetic groove 116. The magnetic member 117 is configured as a permanent magnet. The magnetic member 117 can act together with the electromagnetic force generated by the disk coil 112 to jointly drive the secondary structure 130 to move along the first direction D1. The opening direction of the magnetic groove 116 faces the secondary structure 130. The magnetic member 117 is embedded in the magnetic groove 116. The disk coil 112 is disposed around the magnetic member 117. The fixing surface 114 is configured as a planar structure, and the magnetic member 117 is configured as a flat plate structure. Thus, the processing and installation accuracy are reduced. The length direction of the magnetic member 117 is parallel to the length direction of the first line segment 124, and the length direction of the magnetic member 117 is perpendicular to the first direction D1. Thus, the magnetic member 117 can generate sufficient magnetic force along the first direction D1.

[0090] Magnetic members 117 are disposed between adjacent disk coils 112 along the first direction D1. As an optional implementation manner, the sizes of the magnetic members 117 provided on each first protrusion 113 are the same. In particular, the lengths of the magnetic members 117 provided on each first protrusion 113 are the same. Thus, the magnetic members 117 provided on the multiple first protrusions 113 can all generate electromagnetic forces in the same direction, avoiding disorder caused by the interaction between multiple electromagnetic forces.

[0091] In order to make full use of the electromagnetic force of the disk coil 112, the cross-sectional shape of the first protrusion 113 is configured as a rectangle. In the present embodiment, the "cross-section" is parallel to the first direction D1. 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 disk coil 112 is wound around the first side surface 122 and the second side surface 123. The two first side surfaces 122 are arranged opposite to each other in the first direction D1. The two second side surfaces 123 are arranged opposite to each other 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, it is ensured that the disk coil 112 has a relatively large electromagnetic force in the first direction D1, and further drives the secondary structure 130 to be movable in the first direction D1.

[0092] Furthermore, the cross-sectional shape of the disk coil 112 is configured as a figure-eight shape. The disk coil 112 includes a first line segment 124, and the two first line segments 124 are spaced apart in 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 disk coil 112 are arranged at intervals in the first direction D1, and a first protrusion 113 is arranged between the two first line segments 124 in the first direction D1. Furthermore, the two first line segments 124 of the same disk coil 112 can be respectively located in two adjacent first grooves 111. One first line segment 124 of the same disk coil 112 is located in one first groove 111, and the other first line segment 124 of the same disk coil 112 is located in another first groove 111. In this way, it is ensured that the two first line segments 124 can fully generate a magnetic field force in the first direction D1, and further drives the secondary structure 130 to be movable in the first direction D1.

[0093] The disk coil 112 further includes a second line segment 125, and the first line segment 124 and the second line segment 125 are vertically connected. The two second line segments 125 are arranged opposite to each other in a direction perpendicular to the first direction D1. The second line segment 125 is located between the two first line segments 124 in the first direction D1. The second line segment 125 is parallel to the first direction D1. In this way, the electromagnetic force that the first line segment 124 of the primary structure 110 can generate in the first direction D1, 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 connected path for the current.

[0094] The length of the first line segment 124 is greater than that of the second line segment 125. The first line segment 124 is disposed outside the first side surface 122 and is in contact with the first side surface 122. The second line segment 125 is disposed outside the second side surface 123 and is in contact with the second side surface 123. In this way, it is ensured that the disc coil 112 has a greater electromagnetic force in the first direction D1, and further the secondary structure 130 can be driven to move in the first direction D1.

[0095] The two second line segments 125 of the same disc coil 112 are spaced apart in a direction perpendicular to the first direction D1, and one of the above-mentioned first protrusions 113 is disposed between the two second line segments 125 in the length direction of the first line segment 124. The first groove 111 and the first protrusion 113 are flush with each other in the length direction of the first line segment 124. 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 in the length direction of the first line segment 124. The disc coil 112 is wound around the first protrusion 113. The second line segment 125 is located outside the second side surface 123 in the length direction of the first line segment 124. The second line segment 125 does not cut the magnetic force generated by the disc coil 112, that is, the second line segment 125 does not affect the movement of the secondary structure 130 in the first direction D1.

[0096] Another first protrusion 113 is disposed between two adjacent disc coils 112. In particular, the other first protrusion 113 is located between a first line segment 124 of one disc coil 112 and a first line segment 124 of another disc coil 112. The second line segments 125 of two adjacent disc coils 112 are spaced apart in the first direction D1. Two adjacent disc coils 112 are not in direct contact. In this way, the energization of two adjacent disc coils 112 does not affect each other.

[0097] To avoid short - circuit influence caused by direct contact between the disc coils 112 on adjacent fixing surfaces 114, the first protrusions 113 between adjacent fixing surfaces 114 are spaced apart. As Figure 10As shown, a gap 126 is formed between the first protrusions 113 of adjacent fixed surfaces 114. The gap 126 serves as a heat dissipation channel for the disc coil 112, ensures that the disc coils 112 on adjacent fixed surfaces 114 are spaced apart, and also avoids temperature and electromagnetic interference during operation. Preferably, the gap 126 is also located between the first protrusion 113 of one fixed surface 114 and the disc coil 112 of an adjacent fixed surface 114. Thus, it is ensured that the first protrusion 113 of one fixed surface 114 and the disc coil 112 of another fixed surface 114 are spaced apart to avoid mutual influence. For example, the gap 126 is located between the disc coil 128 of the first fixed surface and the first protrusion 129 of the second fixed surface. The gap 126 can extend along the first direction D1 to form a chamber 127. The chamber 127 is configured as a cuboid structure. Thus, it is ensured that the multiple disc coils 128 of the first fixed surface and the multiple first protrusions 129 of the second fixed surface are all spaced apart, avoiding interference between the multiple disc coils 128 and the multiple first protrusions 129 of adjacent fixed surfaces.

[0098] Figure 4 and Figure 5 The structure of the secondary structure 130 is shown. The secondary structure 130 includes a plurality of second protrusions 132 that protrude in a direction perpendicular to the first direction D1 towards the primary structure 110. 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 opening direction of the second groove 131 faces the primary structure 110. The second protrusions 132 and the second grooves 131 together form an uneven structure. After the disc coil 112 is energized, a magnetic field acts on the uneven structure of the secondary structure 130, so that the electromagnetic force generated after the disc coil 112 is energized can drive the secondary structure 130 to move.

[0099] The second protrusion 132 is located between 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 with at least a part of the projection of the second groove 131. Preferably, the disc coil 112 is at least partially oppositely arranged with the second groove 131. In this way, it is ensured that the electromagnetic force generated when the disc coil 112 is energized acts on the second groove 131, and the magnetic field lines of the magnetic field generated by the disc coil 112 are cut by the second groove 131, thereby driving the secondary structure 130 to move along the first direction D1. The projection of the disc coil 112 in a direction perpendicular to the first direction D1 coincides with at least a part of the projection of the second groove 131. The projection of the disc coil 112 along the length direction of the first line segment 124 coincides with at least a part of the projection of the second groove 131.

[0100] Further, in order to correspond to the primary structure 110, the motor includes a plurality of secondary structures 130, and the plurality of secondary structures 130 respectively correspond to a plurality of fixed surfaces 114. One secondary structure 130 corresponds to one fixed surface 114. The plurality of secondary structures 130 are spaced apart from each other. The included angle formed between adjacent secondary structures 130 is equal to the included angle formed between adjacent fixed surfaces 114. The three-phase windings 120 or multi-phase windings independently formed on each fixed surface 114 can jointly form a plurality of switched-flux linear motor units. Thus, the electromagnetic force output mode of the motor can be made more diverse, increasing the fault tolerance of the system.

[0101] To fix the plurality of secondary structures 130, the motor further includes a support member 160, and the support member is configured as a hollow polyhedral structure. The support member 160 can ensure that the secondary structure 130 faces the disc coil 112. The primary structure 110 and the secondary structure 130 are located in the support member 160 so that the electromagnetic force generated after the disc coil 112 in the support member 160 is energized can drive the secondary structure 130 to move. Moreover, 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 be able to move along the first direction D1.

[0102] Specifically, the support member 160 includes a main body 161, and the main body 161 is configured as a sleeve structure. The main body 161 is used to accommodate the primary structure 110 and the secondary structure 130. The main body 161 includes a main body hole 164, and the length direction of the main body hole 164 is parallel to the first direction D1. The longitudinal cross-sectional shape of the main body hole 164 is quadrilateral. The primary structure 110 and the secondary structure 130 are arranged in the main body hole 164. The shape of the main body hole 164 matches the shape of the primary structure 110.

[0103] The main body 161 can be configured as a polyhedral sleeve structure. The main body 161 includes a plurality of inner surfaces 169, and the plurality of inner surfaces 169 are sequentially connected to each other. An included angle is formed between adjacent inner surfaces 169. It can be understood that the sum of the included angles formed between all inner surfaces 169 should be 360°. One side of one inner surface 169 is connected to one side of an adjacent another inner surface 169, the other side of the another inner surface 169 is connected to one side of a further inner surface 169, and the other side of the further inner surface 169 is connected to the other side of the one inner surface 169. In this way, the plurality of inner surfaces 169 enclose a polyhedral structure.

[0104] The main body 161 is configured as an integral part. The main body 161 is configured as a cuboid sleeve structure, which is simple and reliable in structure and reduces the processing difficulty. The plurality of inner surfaces 169 respectively face the plurality of fixed surfaces 114. Figure 4In the illustrated embodiment, the main body 161 is configured as a tetrahedral sleeve structure. The longitudinal cross-sectional shape of the main body 161 is a quadrilateral ring. Preferably, the longitudinal cross-sectional shape of the main body 161 is a square ring. The main 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 main body 161 may include a prismatic structure with more faces to match the shape of the primary structure 110. For example, the main body 161 may also be configured as a triangular prism structure, a pentagonal prism structure, a hexagonal prism structure or a prismatic structure with more faces according to the shape of the primary structure 110, and this embodiment does not intend to limit this.

[0105] The main body 161 is connected to the secondary structure 130. The main body 161 and the secondary structure 130 are fixedly connected. The main body 161 and the secondary structure 130 are fixedly connected together by bonding or welding. The secondary structure 130 moves to drive the main body 161 to move along the first direction D1. Combining Figure 4 As shown, 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 a secondary structure 130. Thus, a plurality of fixing surfaces 114 of the primary structure 110 are respectively opposite to a plurality of secondary structures 130, so that after the disk coils 112 of each fixing surface 114 are energized, they can act on the corresponding secondary structures 130 respectively, causing the secondary structures 130 to move. A plurality of secondary structures 130 can move at least partially simultaneously to jointly drive the support member 160 to move.

[0106] In order to real-time monitor the moving displacement of the secondary structure 130, a displacement sensor 166 is further provided on the main body 161. The displacement sensor 166 is located at the corner 165 of the main body 161. The displacement sensor 166 is located on the edge of the main body 161. A notch 167 is provided at the corner 165 of the main body 161. The notch 167 is recessed inward from the outer surface of the main body 161. The displacement sensor 166 is located in the notch 167. In this way, the temperature and electromagnetic interference caused by the energization of the disk coil 112 to the displacement sensor 166 are avoided, and the space utilization rate of the support member 160 is improved.

[0107] The support member 160 further includes a guiding portion 163, and the guiding portion 163 is connected to the main body 161. The guiding portion 163 is configured as a rod-shaped structure. The guiding portion 163 is disposed in the main body hole 164. The guiding portion 163 may be connected to the bottom of the interior of the main body 161 along the first direction D1. The guiding portion 163 and the main body 161 may be connected together by welding or integrally formed. The movement of the main body 161 can drive the guiding portion 163 to move.

[0108] The primary structure 110 includes a guiding hole 118, and the axial direction of the guiding hole 118 is parallel to the first direction D1. The guiding portion 163 is inserted into the primary structure 110. In particular, the guiding portion 163 is inserted into the guiding hole 118. The guiding portion 163 is movable relative to the primary structure 110 along the first direction D1. The primary structure 110 functions to constrain the guiding portion 163, thereby achieving radial positioning. Thus, the guiding portion 163 can guide the movement of the secondary structure 130, ensure that the secondary structure 130 moves linearly along the first direction D1, and play a guiding and limiting role to prevent the primary structure 110 and the secondary structure 130 from contacting due to radial unbalanced magnetic pulling force when eccentric, and ensure that there is a constant air gap between the primary structure 110 and the secondary structure 130 when the active suspension 100 operates.

[0109] Figure 1 and Figure 2 An active suspension 100 according to a preferred embodiment provided by the present application is also shown. The active suspension 100 includes the above-mentioned motor.

[0110] According to the active suspension of the present application, the active suspension includes a motor. The motor includes a primary structure 110, a disc coil 112, and a secondary structure 130. The primary structure 110 includes a plurality of fixing surfaces 114. The fixing surfaces 114 are provided with a plurality of first protruding portions 113. The first protruding portions protrude from the fixing surfaces. The plurality of first protruding portions 113 are arranged at intervals along the first direction. The disc coil 112 is arranged around the first protruding portions 113. The circumferential center line of the disc coil 112 is perpendicular to the fixing surface 114. The first direction intersects the circumferential center line. The secondary structure 130 is spaced apart from the primary structure 110. The secondary structure 130 is disposed opposite to the disc coil 112. In this way, the structure is simple and reliable, and the processing difficulty is reduced. The disc coil 112 is arranged around the first protruding portions 113. The electromagnetic force generated by the disc coil 112 can drive the secondary structure 130 to move, thereby driving the wheel to move, so as to reduce the vibration of the vehicle body.

[0111] Preferably, the active suspension 100 is used for a vehicle to reduce the vibration of the vehicle. The vehicle includes a wheel and a vehicle body. The wheel travels on a road surface. The active suspension 100 connects the wheel and the vehicle body. The active suspension 100 can reduce the vibration transmitted from the wheel to the vehicle body. The stiffness and damping characteristics of the active suspension 100 can be dynamically and adaptively adjusted according to the driving conditions of the vehicle (such as the motion state of the vehicle and the road surface condition), so that the active suspension 100 is in the best vibration damping state.

[0112] The primary structure 110 of the motor is for connection to the vehicle body, and the secondary structure 130 is for connection to the wheel. Specifically, one end of the primary structure 110 is for connection to the vehicle body, and one end of the secondary structure 130 is for connection to the wheel. The active suspension 100 further includes an elastic member 150, and both ends of the elastic member 150 are respectively for abutting against the vehicle body and the wheel. In this embodiment, "abutting" may be that the elastic member 150 is in direct contact with the vehicle body or the wheel, or in indirect contact.

[0113] The elastic member 150 is configured as a rigid spring. Both ends of the elastic member 150 in the first direction D1 are respectively connected to the vehicle body and the secondary structure 130. In this embodiment, the "first direction D1" is parallel to the height direction of the vehicle. The elastic member 150 can produce 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 respectively located at both ends of the elastic member 150 in the first direction D1. The first end 151 of the elastic member 150 abuts against the secondary structure 130, and the second end 152 of the elastic member 150 abuts against the primary structure 110.

[0114] Further, the primary structure 110 is for connection to the vehicle body, and the secondary structure 130 is for connection to the wheel. The elastic member 150 can absorb the impact force when driving on a bumpy road surface, thereby playing a shock-absorbing role. 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. The second end 152 of the elastic member 150 can support the vehicle body. The elastic member 150 can play a role in connecting the vehicle body and the secondary structure 130, and the self-weight of the vehicle body can act on the elastic member 150, so that the elastic member 150 can support the vehicle body. The elastic member 150 can transmit the gravity of the vehicle body to the wheel through the secondary structure 130.

[0115] As described above, the active suspension 100 further includes a support member 160, and the support member 160 is connected to the secondary structure 130. The first end 151 of the elastic member 150 may abut against the support member 160. The elastic member 150 abuts against the secondary structure 130 through the support member 160 to prevent the secondary structure 130 from being directly connected to the elastic member 150 and prevent the structure of the secondary structure 130 from being damaged.

[0116] The secondary structure 130 is also used to connect to the wheel through the support member 160. The support member 160 includes a ring portion 168, which is located at the bottom of the support member 160. The ring portion 168 is used to connect to the axle of the wheel. The support member 160 also includes a support plate 162, which protrudes from the main body 161. The main body 161 also includes an outer surface 170. The support plate 162 is connected to the outer surface 170 of the main body 161. In this embodiment, the "outer surface 170 of the main body 161" refers to the surface of the main body 161 that faces away from the secondary structure 130. The support plate 162 is constructed as a flat plate structure, which is simple in structure and easy to process. The support plate 162 is arranged around the main body 161. A portion of the main body 161 is inserted into the elastic member 150. The support plate 162 is spaced apart from the end of the main body 161 along the first direction D1. The support plate 162 abuts against the first end 151 of the elastic member 150. The elastic force of the elastic member 150 acts on the support plate 162 so that the support member 160 is subjected to uniform force.

[0117] The active suspension 100 further includes a connecting member 180, which is fixedly connected to the primary structure 110. The connecting member 180 and the primary structure 110 can be connected together by welding or threaded connection. The primary structure 110 is used to be connected to the vehicle body through the connecting member 180. The second end 152 of the elastic member 150 is against the connecting member 180. In this way, the elastic member 150 is against the connecting member 180 to avoid the primary structure 110 and the vehicle body being directly connected to the elastic member 150, and to prevent the structure of the primary structure 110 from being damaged and affecting the generation of electromagnetic force.

[0118] Specifically, the connecting member 180 includes an abutting plate 181, and the abutting plate 181 abuts against the second end 152 of the elastic member 150. The elastic member 150 is located between the abutting plate 181 and the support plate 162. The elastic force of the elastic member 150 acts on the abutting plate 181. The abutting plate 181 is constructed as a flat plate structure, which is simple in structure and easy to process. The elastic force of the elastic member 150 acts on the abutting plate 181, so that the connecting member 180 is subjected to uniform force, thereby causing the vehicle body to be subjected to uniform force.

[0119] The connecting member 180 further includes a mating portion 182 that protrudes from the abutting plate 181 along the first direction D1. The mating portion 182 can be configured as a rod-shaped structure. The axial direction of the mating portion 182 is parallel to the first direction D1. The mating portion 182 protrudes along the first direction D1 toward the primary structure 110. A part of the mating portion 182 is inserted into and passes through the elastic member 150. The mating portion 182 is inserted into the support member 160 along the first direction D1. The mating portion 182 is connected to the primary structure 110 so that the primary structure 110 and the connecting member 180 are connected together. One end of the mating portion 182 along the first direction D1 is for connecting to the vehicle body, and the other end of the mating portion 182 along the first direction D1 is connected to the primary structure 110. The primary structure 110 and the mating portion 182 can be connected 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.

[0120] More specifically, the primary structure 110 includes a guide hole 118 whose length direction is parallel to the first direction D1. The mating portion 182 is inserted into the guide hole 118 along the first direction D1 and the mating portion 182 is fixedly connected to the primary structure 110. The mating portion 182 and the primary structure 110 can be fixed together by welding, bonding or threaded connection. The guide hole 118 can be configured as a circular hole. The mating portion 182 is configured as a cylindrical structure. The shapes of the mating portion 182 and the guide hole 118 match. The mating portion 182 and the guide hole 118 are fixed together. Of course, the guide hole 118 can also be configured as a polygonal hole, the mating portion 182 is configured as a polyhedral structure, and the shapes of the mating portion 182 and the guide hole 118 match. This embodiment does not intend to limit this.

[0121] The mating portion 182 includes a mating hole 183, and the axial direction of the mating hole 183 is parallel to the axial direction of the guiding hole 118. The mating hole 183 and the guiding hole 118 are coaxially arranged. The length direction of the mating hole 183 is parallel to the first direction D1. The guiding portion 163 of the support member 160 is inserted into the mating hole 183. The mating hole 183 is configured as a circular hole, and the guiding portion 163 is configured as a cylindrical structure. The guiding portion 163 is inserted into the mating hole 183, so that the guiding portion 163 is inserted into the primary structure 110. The guiding portion 163 can move relative to the mating hole 183 along the first direction D1 together with the support member 160. Thereby, the mating hole 183 exerts a constraint on the guiding portion 163, so as to realize radial positioning, ensure that the secondary structure 130 can move linearly along the first direction D1, play a guiding and limiting role, and prevent the primary structure 110 and the secondary structure 130 from contacting due to radial unbalanced magnetic pulling force when they are eccentric, and ensure that there is a constant air gap between the primary structure 110 and the secondary structure 130 when the active suspension 100 works. Of course, the mating hole 183 can also be configured as a polygonal hole, the guiding portion 163 is configured as a polyhedral structure, and the shapes of the guiding portion 163 and the mating hole 183 match. The present embodiment does not intend to limit this.

[0122] When the vehicle is traveling 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. When the disc coil 112 is not energized, the vehicle can also directly reduce vibrations through the elastic member 150.

[0123] For example, as Figure 1 shown, the guiding portion 163 can be in close contact with the top surface of the mating hole 183. When the vehicle is traveling on a potholed road surface, 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 able to move away from the abutting plate 181 along the first direction D1. The secondary structure 130 can drive the guiding portion 163 to move away from the abutting plate 181, so that the guiding portion 163 is spaced apart from the top surface of the mating hole 183. In this way, the secondary structure 130 can drive the support 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 elongate, thereby driving the wheel to move downward to fit the pothole surface, thereby reducing the vibration of the vehicle body.

[0124] As Figure 2As shown, the guiding part 163 and the top surface of the mating hole 183 can 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 towards the abutting plate 181. The secondary structure 130 can drive the guiding part 163 to move towards the abutting plate 181, so that the guiding part 163 fits with the top surface of the mating hole 183. In this way, the secondary structure 130 can drive the supporting member 160 to move upward in the height direction of the vehicle, so that the first end 151 of the elastic member 150 moves upward in the first direction D1 to be compressed, thereby driving the wheel to move upward to fit with the steep road surface, thus reducing the vibration of the vehicle body.

[0125] The present application also provides a vehicle, and the vehicle includes the above-mentioned motor.

[0126] According to the vehicle of the present application, the vehicle includes the above-mentioned motor. The motor includes a primary structure 110, a disc coil 112, and a secondary structure 130. The primary structure 110 includes a plurality of fixing surfaces 114. The fixing surfaces 114 are provided with a plurality of first protruding parts 113. The first protruding parts protrude from the fixing surfaces. The plurality of first protruding parts 113 are arranged at intervals in the first direction. The disc coil 112 is arranged around the first protruding parts 113. The circumferential center line of the disc coil 112 is perpendicular to the fixing surface 114. The first direction intersects with the circumferential center line. The secondary structure 130 is spaced apart from the primary structure 110, and the secondary structure 130 is arranged opposite to the disc coil 112. In this way, the structure is simple and reliable, the processing difficulty is reduced. The disc coil 112 is arranged around the first protruding parts 113, and the electromagnetic force generated by the disc coil 112 can drive the secondary structure 130 to move, thereby driving the wheel to move, so as to reduce the vibration of the vehicle body.

[0127] The vehicle further includes a vehicle body and wheels. The primary structure 110 of the motor is connected to the vehicle body, and the secondary structure 130 is connected to the wheels. Specifically, the top of the primary structure 110 is connected to the vehicle body, and the bottom of the secondary structure 130 is connected to the wheels. The top of the primary structure 110 and the bottom of the secondary structure 130 are respectively located at both ends of the motor in the height direction of the vehicle. In this way, the vibration of the vehicle body can be reduced.

[0128] The vehicle further includes a plurality of road condition sensors and a control device. The plurality of road condition sensors are installed on the vehicle body. The road condition sensors can monitor the road conditions in real time. The plurality of road condition sensors and the control device are electrically connected to feedback the monitored data to the control device. The control device is electrically connected to the power supply to control the current direction according to the data feedback by the road condition sensors. Thus, the moving direction of the secondary structure 130 can be controlled in time. The control device can also control the magnitude of the current according to the data feedback by the road condition sensors. Thus, the moving displacement of the secondary structure 130 can be controlled in time.

[0129] The present application also provides a vehicle, which includes the above-mentioned active suspension 100.

[0130] According to the vehicle of the present application, the vehicle includes the above-mentioned active suspension 100. The active suspension 100 includes the above-mentioned motor.
