[0207] In the description of the present invention, features defined as "first", "second" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0208] The electromagnetic actuator 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings of the specification.

[0209] As Fig. 22 shown, an electromagnetic actuator 1000 according to an embodiment of the present invention includes: a first component 220, a second component 210, and a detection module 900.

[0210] Wherein, the second component 210 and the first component 220 are coupled so that the first component 220 and the second component 210 can move relative to each other.

[0211] The detection module 900 is configured to detect the relative displacement between the first component 220 and the second component 210.

[0212] From the above structure, it can be seen that for the electromagnetic actuator 1000 according to the embodiment of the present invention, by providing the detection module 900 to detect the relative displacement between the first component 220 and the second component 210, the position of the second component 210 can be accurately determined, which is convenient for controlling the movement of the second component 210 and ensuring the position accuracy of the second component 210 after movement, thereby improving the working performance of the electromagnetic actuator 1000.

[0213] At the same time, using the detection module 900 to detect the relative displacement between the first component 220 and the second component 210 can also reduce the difficulty of detecting the position of the second component 210 and ensure the accuracy of detecting the position of the second component 210.

[0214] It can be understood that, compared with the prior art, the electromagnetic actuator 1000 of the present application is provided with a detection module 900 to ensure the control accuracy of the moving position of the second component 210, thereby avoiding the technical problem of control accuracy defects.

[0215] In some embodiments, the detection module 900 can sense the signals corresponding to different positions of the device to be measured and output position signals to the controller through wires, so as to achieve the purpose of detecting the relative displacement between the first component 220 and the second component 210.

[0216] In some embodiments, as Fig. 22 shown, the electromagnetic actuator 1000 further includes a housing 100. An accommodation cavity 130 is formed in the housing 100. Both the first component 220 and the second component 210 are arranged in the accommodation cavity 130. One of the first component 220 and the second component 210 is connected to the housing 100. The first component 220 and the second component 210 are coupled so that one of the first component 220 and the second component 210 moves along the axis with the housing 100. Thereby ensuring the working performance of the electromagnetic actuator 1000.

[0217] In some embodiments, the first component 220 is arranged in the housing 100. Therefore, the detection module 900 detecting the relative displacement between the first component 220 and the second component 210 can also be understood as the detection module 900 detecting the relative displacement between the housing 100 and the second component 210.

[0218] In some embodiments, in combination with Figure 141-146 shown, the detection module 900 includes a laser sensor 910. The laser sensor 910 is arranged at the top or bottom of the accommodation cavity 130. Thereby facilitating the use of the laser sensor 910 to detect the relative displacement between the housing 100 and the second component 210, ensuring the accuracy of the detection of the relative displacement between the housing 100 and the second component 210, and reducing the detection difficulty of the relative displacement between the housing 100 and the second component 210.

[0219] In some embodiments, in combination with Fig.141 and Fig.142As shown, the housing 100 is adapted to be fixed to the axle. The electromagnetic actuator 1000 further includes a mounting bracket 192. The mounting bracket 192 is mounted on the outer side of the housing 100 and is adapted to connect the axle and the housing 100. The laser sensor 910 is disposed within the mounting bracket 192. An avoidance hole 131 for avoiding the optical path of the laser sensor 910 is provided on the bottom wall of the accommodation cavity 130. Among them, by disposing the laser sensor 910 in the mounting bracket 192, the laser sensor 910 is disposed on the housing 100, which facilitates using the housing 100 to support the laser sensor 910, improves the position stability of the laser sensor 910, and because the avoidance hole 131 for avoiding the optical path of the laser sensor 910 is provided on the bottom wall of the accommodation cavity 130, the optical path generated by the laser sensor 910 disposed on the mounting bracket 192 can be projected into the accommodation cavity 130, so as to facilitate using the laser sensor 910 to detect the relative displacement between the housing 100 and the second component 210.

[0220] In some embodiments, as Fig.143 shown, one end of the mounting bracket 192 is provided with a first sensor mounting bracket 920. The laser sensor 910 is disposed on the first sensor mounting bracket 920, so as to dispose the laser sensor 910 on the mounting bracket 192, which facilitates using the housing 100 to support the laser sensor 910, improves the position stability of the laser sensor 910, and reduces the fixing difficulty of the laser sensor 910.

[0221] Among them, the fixing manner of the laser sensor 910 and the first sensor mounting bracket 920 may be bolt connection.

[0222] In some embodiments, in combination with Figure 142-146 shown, in the axial direction of the electromagnetic actuator 1000, the laser sensor 910 faces the second component 210. In this way, the optical path generated by the laser sensor 910 can be projected onto the second component 210, so as to facilitate using the laser sensor 910 to detect the relative displacement between the housing 100 and the second component 210.

[0223] In a specific example, the laser sensor 910 mainly determines the position by sensing the reflected light of an object and outputs the displacement signal of the electromagnetic actuator 1000. Its working principle is that before the electromagnetic actuator 1000 starts, the height of the laser sensor 910 is first calibrated and the position of the laser sensor 910 is measured. After the housing 100 moves upward relative to the second component 210 (such as Fig.144As shown, at this time, the laser sensor 910 projects a visible light spot on the surface of the second component 210. The light reflected from the light spot is imaged on the photosensitive element in the laser sensor 910 through the light receiving system. When the distance between the laser sensor 910 and the second component 210 changes, the laser reflection angle also changes accordingly, causing the imaging position on the photosensitive element in the laser sensor 910 to change, thereby measuring the current position of the laser sensor 910 and the second component 210. When the housing 100 moves downward relative to the second component 210 (as Fig.145 shown), the laser sensor 910 measures the current position of the laser sensor 910 and the second component 210 again according to the above method. By analyzing the change in the position values before and after, the relative displacement between the housing 100 and the second component 210 can be obtained, achieving the purpose of detecting the relative displacement between the housing 100 and the second component 210.

[0224] Through the above settings, this embodiment can be formed into an active measurement with a high measurement frequency, and the height parameter of the electromagnetic actuator 1000 can be obtained in real time. Whether it is low-frequency vibration or even the vehicle in a stationary state, it does not affect the measurement parameters, that is, the vehicle attitude and other information can still be provided well when the vehicle is in a stationary state. Therefore, the laser sensor 910 in this embodiment can not only be used to measure the stroke of the electromagnetic actuator 1000, but also obtain the movement speed of the electromagnetic actuator 1000 through the functional relationship between the difference in the stroke of the electromagnetic actuator 1000 and time. Fig.144 and Fig.145 taking... as an example, within one reflection and reception cycle time of the laser sensor 910, the position of the housing 100 changes from Fig.144 to Fig.145 . Based on this, the average speed of the electromagnetic actuator 1000 within one laser reflection and reception cycle can be calculated. Because the measurement frequency of the laser sensor 910 is high, to a certain extent, this speed can reflect the real-time speed of the movement of the electromagnetic actuator 1000.

[0225] In a specific example, the load of different axles of the vehicle can be initially estimated by comparing the initial state of the vehicle. The basic principle is that when the vehicle starts or is about to move, the heights of the four wheels of the vehicle are measured. At this time, there is no relative movement and road surface impact on the vehicle, and the distance change can be regarded as caused by the load compression damping. Based on this, the empty and full load states of the vehicle can be judged, and thus a more accurate reference basis can be provided for four-wheel control.

[0226] Similarly, the change in the different speeds of the electromagnetic actuator 1000 within one laser reflection and reception cycle can reflect the real-time acceleration of the electromagnetic actuator 1000 to a certain extent. In theory, the number of sensors installed on the vehicle can be greatly reduced, achieving the purpose of saving design.

[0227] It should also be noted that in this embodiment, the laser sensor 910 is arranged at the bottom of the electromagnetic actuator 1000, and the detected position is the bottom plane of the second component. Since the main movements of the housing 100 and the second component 210 are linear movements in the up and down directions, in the actual movement scenario, the housing 100 and the second component 210 may also rotate relative to the second component 210. Through the above settings, even if the housing 100 and the second component 210 are deflected, it can be ensured that the top of the mounting bracket 192, the laser sensor 910, and the bottom surface of the second component 210 are parallel (as Fig.146 shown), so as to avoid the position data detected by the laser sensor 910 being affected by the deflection of the housing 100 and the second component 210.

[0228] At the same time, since the laser sensor 910 is installed on the mounting bracket 192, it can also avoid the high temperature generated during the movement of the electromagnetic actuator 1000 from interfering with the laser sensor 910, ensure the working performance of the laser sensor 910, and at the same time make the laser sensor 910 installed outside the electromagnetic actuator 1000, which is more convenient for the replacement and installation of the laser sensor 910 and is more conducive to after-sales replacement and maintenance.

[0229] In summary, this embodiment makes full use of the mounting bracket 192, and the laser sensor 910 with higher measurement accuracy well compensates for the various deficiencies of the traditional sensor, comprehensively exceeding the traditional design in terms of layout space, measurement accuracy, measurement content, service life, and maintenance convenience.

[0230] In some embodiments, as shown in combination with Figure 150-163 the electromagnetic actuator 1000 further includes a central rod 300. The central rod 300 connects the first component 220 and the other of the second components 210. The detection module 900 includes a first detection member 930 and a second detection member 940. The second detection member 940 is coupled with the first detection member 930. One of the housing 100 and the central rod 300 is provided with the first detection member 930 and the other is provided with the second detection member 940. Thereby, it is convenient to use the second detection member 940 and the first detection member 930 to cooperate to detect the relative displacement of the housing 100 and the second component 210, ensure the accuracy of the position detection of the second component 210, and reduce the difficulty of the position detection of the second component 210.

[0231] In some embodiments, as shown in combination with Figure 150-163As shown, the housing 100 is adapted to be fixed to the axle, and the central rod 300 passes through the top wall of the housing 100 to be connected to the vehicle body; the first detecting member 930 is disposed on the housing 100, and the second detecting member 940 is disposed on the central rod 300. The housing 100 is used to support the first detecting member 930 and the central rod 300 is used to support the second detecting member 940, so as to improve the position stability of the first detecting member 930 and the second detecting member 940, and facilitate the use of the second detecting member 940 and the first detecting member 930 to cooperate to detect the relative displacement between the housing 100 and the second component 210.

[0232] In some embodiments, in combination with Figure 147-Figure 150 As shown, an assembly groove 950 is provided on the central rod 300 (for the specific structure of the assembly groove 950, reference can be made to Fig.25 ), the second detecting member 940 is fixed on the assembly groove 950 of the central rod 300, a sensor mounting groove 960 is provided on the housing 100 opposite to the assembly groove 950, and the first detecting member 930 is disposed in the sensor mounting groove 960, forming a complete working environment for the position sensor, so as to facilitate the use of the second detecting member 940 and the first detecting member 930 to detect the relative displacement between the housing 100 and the second component 210.

[0233] In some embodiments, in combination with Figure 151-154 As shown, the first detecting member 930 is disposed on the outer side of the housing 100. This can reduce the installation difficulty of the first detecting member 930, and at the same time, it is also beneficial to replace and repair the first detecting member 930, reducing the maintenance difficulty of the first detecting member 930.

[0234] At the same time, by disposing the first detecting member 930 on the outer side of the housing 100, the high-temperature area of the housing 100 can be effectively avoided, and the first detecting member 930 can use natural wind for heat dissipation, fully protecting the first detecting member 930 and avoiding the failure of the first detecting member 930 to a certain extent.

[0235] In some embodiments, as Fig.152 shown, a bearing 170 is provided between the central rod 300 and the housing 100, and a part of the projection of the first detecting member 930 in the radial direction that coincides with the housing 100 overlaps with a part of the projection of the bearing 170 in the radial direction. That is to say, in the radial direction of the housing 100, the first detecting member 930 and the bearing 170 partially overlap. In this way, on the premise that the extension length of the central rod 300 is certain, it can be avoided that the extension length of the bearing 170 is excessively reduced due to the setting of the first detecting member 930. That is, by making the first detecting member 930 and the bearing 170 partially overlap, the extension length of the bearing 170 can be ensured, thereby ensuring the guiding effect of the bearing 170.

[0236] In some embodiments, the bearing 170 is provided with a sensor avoidance groove, and the first detection member 930 is disposed in the sensor avoidance groove, such that a part of the projection of the first detection member 930 in the radial direction overlapping with the housing 100 partially overlaps with the projection of the bearing 170 in the radial direction. At the same time, the fixing difficulty of the first detection member 930 can be reduced, and the position stability of the first detection member 930 can be improved, to a certain extent ensuring the working performance of the first detection member 930.

[0237] In some embodiments, a bearing 170 is disposed between the central rod 300 and the housing 100, and the first detection member 930 is spaced apart from the bearing 170. That is to say, it is not limited to the situation that a part of the projection of the first detection member 930 in the radial direction overlapping with the housing 100 partially overlaps with the projection of the bearing 170 in the radial direction. The first detection member 930 and the bearing 170 can also be spaced apart, such that the first detection member 930 and the bearing 170 are independent of each other, ensuring the working performance of the first detection member 930 and the bearing 170.

[0238] Herein, the so-called spaced-apart setting can be understood as that the first detection member 930 and the bearing 170 are spaced apart in the axial direction of the central rod 300, such that the first detection member 930 and the bearing 170 are independent of each other.

[0239] Meanwhile, by disposing the bearing 170 between the central rod 300 and the housing 100, the movement of the central rod 300 is limited. In this way, the central rod 300 moves along the bearing 170, avoiding the offset as shown in Fig.158 during the movement of the vehicle. Among them, the larger the offset angle generated by the central rod 300, the greater the influence on the detection accuracy of the first detection member 930 and the second detection member 940, and even failure may occur.

[0240] Thus, by disposing the bearing 170, the first detection member 930 has better alignment with the second detection member 940 during the movement process, with higher detection accuracy. Thus, it is ensured that during the normal operation of the detection module 900, the working surface of the first detection member 930 needs to be parallel to the working surface of the second detection member 940 (as shown in Fig.157 ). In this way, it can be ensured that the second detection member 940 can obtain accurate magnetic field signals, thereby ensuring the working performance of the detection module 900.

[0241] In some embodiments, as shown in Fig.148 the bearing 170 covers above the first detection member 930, protecting and shielding the stroke of the first detection member 930, and avoiding the housing 100 squeezing the first detection member 930 when moving upward, ensuring the performance of the first detection member 930.

[0242] In some embodiments, as shown in Fig.150As shown, the central rod 300 is provided with a first anti-rotation portion 370, and the housing 100 is provided with an anti-rotation hole 193. The anti-rotation post passes through the anti-rotation hole 193 and extends into the first anti-rotation portion 370 to limit the rotational freedom of the central rod 300, avoiding relative rotation between the central rod 300 and the housing 100, so that the second detection member 940 located on the central rod 300 can be accurately aligned with the first detection member 930 located on the housing 100, ensuring the detection performance of the detection module 900.

[0243] In some embodiments, the first detection member 930 forms a magnetic field induction element, and the second detection member 940 forms a magnetic field output element. As Fig.155 shown, the second detection member 940 can obtain displacement by inducing the magnetic field of the second detection member 940 within a certain stroke range, and the magnetic field signals at any two different positions within the stroke are different, such as a linear relationship; as Fig.156 shown, the second detection member 940 can sense the magnetic field signal emitted by the first detection member 930 and then convert it into an electrical signal, and the electrical signals at any two different positions within the stroke are different, such as a linear relationship. There are many means of conversion here, such as the Hall principle. Finally, the sensed electrical signal (or converted into other signals, such as digital signals) is transmitted as an output signal to achieve the purpose of detecting the relative displacement between the housing 100 and the second component 210 by using the cooperation between the second detection member 940 and the first detection member 930.

[0244] In summary, the first detection member 930 mainly realizes the detection of the relative displacement between the housing 100 and the second component 210 by identifying the magnetic field signal of the second detection member 940. However, the magnetic field intensities emitted by the first component 220 and the second component 210 in the electromagnetic actuator 1000 are very high, which easily interferes with the detection accuracy of the first detection member 930, resulting in a decrease in the accuracy of the detection module 900 or even failure.

[0245] To solve the above problems, the central rod 300 and the housing 100 can be made of magnetic conductive materials. As Fig.153 shown, the magnetic field generated by the first component 220 and the second component 210 inside the electromagnetic actuator 1000 is distributed along the central rod 300 and the housing 100 and forms a closed magnetic field loop, making the magnetic field intensity at the position of the second detection member 940 significantly increased, thus preventing the magnetic field generated by the first component 220 and the second component 210 inside the electromagnetic actuator 1000 from becoming Fig.154 the divergent shape in

[0246] At the same time, the distance between the detection module 900 and the first component 220 and the second component 210 can also be increased to improve the magnetic field intensity at the position of the second detection member 940, making the magnetic field intensity at the position of the second detection member 940 significantly increased and ensuring the detection accuracy of the detection module 900.

[0247] In some embodiments, in combination with Figure 159-164 As shown, an installation bracket 192 is provided at the bottom of the housing 100, and an avoidance channel 1921 communicating with the accommodation cavity 130 is provided in the installation bracket 192; at least a part of the second detection member 940 is located in the avoidance channel 1921, and the first detection member 930 can be moved into the avoidance channel 1921 to be coupled with the second detection member 940. Thereby, it is convenient to use the second detection member 940 and the first detection member 930 to cooperate to detect the relative displacement between the housing 100 and the second component 210, ensure the accuracy of the position detection of the second component 210, and reduce the difficulty of the position detection of the second component 210.

[0248] Meanwhile, by arranging at least a part of the second detection member 940 in the avoidance channel 1921, it is convenient to reduce the space reserved by the electromagnetic actuator 1000 for the detection module 900, which is beneficial to the miniaturized design of the electromagnetic actuator 1000.

[0249] In some embodiments, in combination with Fig.159 、 Fig.160 and Fig.161 As shown, the first detection member 930 includes a sensor connection end 931, a connecting rod 932 and a sensing head 933. The first detection member 930 is fixed to the central rod 300 through the sensor connection end 931, and the fixing method can be bolt connection. The wire harness of the first detection member 930 is arranged inside the connecting rod 932 and connected to the sensing head 933. The sensing head 933 can sense the magnetic field intensity at different regions on the second detection member 940. By analyzing the different magnetic field intensities sensed by the sensing head 933, the relative displacement between the housing 100 and the second component 210 can be determined.

[0250] In some embodiments, at least a part of the second detection member 940 is attached in the avoidance channel 1921. Here, it can be fixed by adhesive bonding.

[0251] In some embodiments, the second detection member 940 is a magnetic grating ruler, which is a device with its own magnetic field. The first detection member 930 is a Hall sensor. The Hall sensor outputs a displacement signal by sensing the change of the magnetic field on the surface of the magnetic grating ruler, so as to achieve the purpose of detecting the relative displacement between the housing 100 and the second component 210.

[0252] In some embodiments, since both the first component 220 and the second component 210 generate magnetic fields, and after the housing 100 moves upward, in combination with Fig.162 and Fig.163As shown, the second detection component 940 is relatively close to the first component 220 and the second component 210. Therefore, the housing 100, the central rod 300, the connecting rod 932, and the mounting bracket 192 are all supported by non-magnetic materials, such as aluminum alloy materials. The use of the above materials can well shield the magnetic fields generated by the first component 220 and the second component 210 around the first detection component 930 and the second detection component 940, ensuring the detection accuracy of the detection module 900.

[0253] In some embodiments, the coercivity of the second detection component 940 is higher than that of the first component 220 to ensure that the second detection component 940 is not magnetized by the first component 220, thereby ensuring the performance of the second detection component 940.

[0254] In some embodiments, as Figure 164-Figure 167 shown, the second detection component 940 is formed in an arc shape. To avoid the induction failure between the second detection component 940 and the first detection component 930 when the first component 220 and the second component 210 rotate relative to each other, and further facilitate ensuring that the first detection component 930 can stably sense the magnetic field intensities at different positions on the second detection component 940, ensuring the detection accuracy of the detection module 900.

[0255] Among them, the radius of the arc shape can be adaptively adjusted according to the radius of the housing 100, and the angle of the arc shape can be determined according to the limit angle of the relative rotation of the first component 220 and the second component 210.

[0256] In some embodiments, an arc-shaped hole is opened on the mounting bracket 192, and the first detection component 930 is arranged in the arc-shaped hole, providing space for the up-and-down movement and rotational movement of the first detection component 930 in the working state.

[0257] In some embodiments, in combination with Figure 165-167 shown, the detection module 900 includes a second detection component 940, a first detection component 930, and a second sensor mounting bracket 970. Among them, the second detection component 940 is a sensor magnetic grating scale, the first detection component 930 is a sensor read head, the second sensor mounting bracket 970 is used to install and fix the sensor magnetic grating scale, the sensor magnetic grating scale provides a magnetic field, and the sensor read head is used to sense the magnetic field intensities at different positions of the magnetic grating scale to detect the relative displacement between the housing 100 and the second component 210.

[0258] At the same time, by setting the second sensor mounting bracket 970, the fixation of the detection module 900 can be made more reliable, improving the position stability of the detection module 900.

[0259] Among them, the magnetic scale is composed of magnetic strips of different sizes and intervals and adopts a single track structure, so that the second detection member 940 is formed into a coded magnetic scale sensor for providing an aperiodic magnetic field, and the sensor head can sense that the combined magnetic field in the non-coded area is unique throughout the entire stroke at the same time, so that the absolute position of the first detection member 930 can be determined, ensuring the detection accuracy of the detection module 900.

[0260] In some embodiments, the second detection member 940 is made of a strong magnetic material such as neodymium iron boron, so that the second detection member 940 has a high coercive force, can adapt to a more complex magnetic field environment, and effectively avoids the risk of demagnetization.

[0261] At the same time, by setting the second detection member 940 to adopt a single track structure, compared with the double track structure, the width of the second sensor mounting bracket 970 and the size of the head of the first detection member 930 can be effectively reduced, the layout space of the first detection member 930 can be effectively reduced, and there are more choices for the layout position of the first detection member 930.

[0262] In some embodiments, in combination Figure 168-Figure 173 As shown, a wire groove 194 for guiding the wires of the detection module 900 is provided on the outer peripheral wall of the housing 100. Among them, by setting wires electrically connected to the detection module 900, the signals detected by the detection module 900 can be transmitted to the controller through the wires, and the controller judges the position of the housing 100 through signal processing, so as to achieve the purpose of detecting the moving position of the housing 100 by using the detection module 900.

[0263] At the same time, by providing a wire groove 194 for guiding the wires on the housing 100, the wiring difficulty of the wires can be reduced. At the same time, the wire groove 194 can also be used to fix the wires, ensuring the position stability of the wires, avoiding the wires from being bent as the housing 100 moves and affecting the signal transmission, thereby improving the reliability of the electromagnetic actuator 1000, and the wire groove 194 can be used to protect the wires, extend the service life of the wires, improve the use safety of the wires, and improve the use reliability of the wires.

[0264] It should be noted that the length of the wire groove 194 can be set according to the position of the external connector, and the depth of the wire groove 194 can be set according to the radial dimension of the wire and the structural strength of the outer shell 210, which is not limited here.

[0265] Optionally, the wire groove 194 is integrally formed with the housing 100. That is to say, the wire groove 194 is integrally formed on the housing 100 to reduce the forming difficulty of the wire groove 194.

[0266] In some embodiments, in combination Fig.168 、 Fig.169 and Fig.170As shown, a plurality of second reinforcing ribs 195 are provided on the outer peripheral wall of the housing 100, and a wire groove 194 is defined between at least two adjacent second reinforcing ribs 195. This is to further reduce the forming difficulty of the wire groove 194.

[0267] Meanwhile, by providing a plurality of second reinforcing ribs 195 on the outer peripheral wall of the housing 100, the structural strength of the housing 100 can be improved, the service life of the housing 100 can be extended, and the wall thickness of the housing 100 can be correspondingly reduced to achieve the purpose of light weight.

[0268] In some embodiments, as shown in Fig.168 and Fig.169 a plurality of second reinforcing ribs 195 are provided on the outer peripheral wall of the housing 100. At least a part of the second reinforcing ribs 195 extend along the radial direction of the housing 100, and at least a part of the second reinforcing ribs 195 extend along the axial direction of the housing 100, so that a plurality of second reinforcing ribs 195 are vertically and horizontally uniformly arranged on the housing 100. This uniformly distributed structural feature is beneficial to the processing technology design of the housing 100.

[0269] Among them, the second reinforcing ribs 195 extending along the radial direction of the housing 100 are mainly used to enhance the bending stiffness of the housing 100, and the second reinforcing ribs 195 extending along the axial direction of the housing 100 are mainly used to enhance the compressive strength of the motor housing 5.

[0270] Meanwhile, diagonal reinforcing ribs can also be provided on the outer peripheral wall of the housing 100 to avoid stress concentration.

[0271] In some embodiments, as shown in Fig.168 and Fig.169 a triangular vertical reinforcing rib is designed at the lower end of the mounting seat 191. By using the principle of the stability of the triangular structure, the structure of the mounting seat 191 is made more stable, it can withstand greater spring elastic force, and the compressive strength of the mounting seat 191 is improved.

[0272] In some embodiments, a second reinforcing rib 195 extending along the axial direction of the housing 100 is also arranged between two adjacent triangular vertical reinforcing ribs, which is used to improve the bending stiffness of the mounting seat 191.

[0273] In some embodiments, a wire avoidance structure is provided between the mounting seat 191 and the housing 100, so that the wire can pass through the mounting seat 191 and be arranged in the wire groove 194.

[0274] In some embodiments, the wire groove 194 is formed into a heat dissipation structure to dissipate heat from the electromagnetic actuator 1000 and ensure the performance of the electromagnetic actuator 1000.

[0275] In some embodiments, the second reinforcing rib 195 can be utilized to expand the heat dissipation area of the housing 100, eliminating the need for an additional heat dissipation cavity for heat dissipation, reducing the redundancy of the mechanism, increasing the degree of freedom in the overall layout design, and achieving the purpose of weight reduction.

[0276] Among them, the depth and width of the second reinforcing rib 195 can be changed according to the diameter of the wire and the strength of the housing 100.

[0277] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 as shown, the housing 100 includes a plurality of sub-housings 101, and the plurality of sub-housings 101 are connected to define a receiving cavity 130.

[0278] It should be noted that in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more. That is to say, the housing 100 includes at least two sub-housings 101, and at least two sub-housings 101 are connected to define a receiving cavity 130. In this way, while reducing the assembly difficulty of the housing 100, the forming difficulty of the receiving cavity 130 can also be reduced, and the maintainability can be improved.

[0279] In combination Figure 1-Figure 4 as shown, a first component 220 is disposed in the receiving cavity 130, a second component 210 is disposed in the receiving cavity 130, and one of the first component 220 and the second component 210 is connected to the housing 100. That is to say, both the first component 220 and the second component 210 are disposed in the receiving cavity 130. On the one hand, the housing 100 can be used to support one of the first component 220 and the second component 210, thereby improving the position stability of one of the first component 220 and the second component 210, and to a certain extent ensuring the working performance of the first component 220 and the second component 210. On the other hand, the housing 100 can also be used to protect the first component 220 and the second component 210, extend the service life of the first component 220 and the second component 210, and thus reduce the use cost of the first component 220 and the second component 210.

[0280] It can be understood that the connection of one of the first component 220 and the second component 210 to the housing 100 means that one of the first component 220 and the second component 210 is fixedly connected to the housing 100.

[0281] Meanwhile, by configuring the housing 100 to include a plurality of sub-housings 101, such that the housing 100 is composed of multiple separate parts, when assembling the first component 220 and the second component 210, the first component 220 and the second component 210 can first be disposed between the plurality of sub-housings 101, and then the plurality of sub-housings 101 are connected, thereby reducing the assembly difficulty of the first component 220 and the second component 210, improving the assembly effect, and also avoiding, to a certain extent, the first component 220 and the second component 210 hitting the housing 100 during the assembly process, thus preventing damage to the first component 220 and the second component 210, further extending the service life of the first component 220 and the second component 210, and ensuring the working performance of the first component 220 and the second component 210.

[0282] In addition, through the above configuration, when it is necessary to maintain or repair the first component 220 and the second component 210, the housing 100 can be directly opened, thereby reducing the maintenance difficulty of the first component 220 and the second component 210 during use.

[0283] The first component 220 and the second component 210 are coupled such that the other of the first component 220 and the second component 210 moves along the axis with the housing 100, thereby driving the component connected to the housing 100 in the first component 220 and the second component 210 to move along the axis. Herein, the axis mentioned can be understood as a straight line extending along the axial direction of the electromagnetic actuator 1000, that is, Figure 2 the straight line extending in the up and down direction in

[0284] That is to say, one of the first component 220 and the second component 210 is connected to the housing 100. When the first component 220 and the second component 210 are in a coupled fit, one of the first component 220 and the second component 210 moves along the axis together with the housing 100, thereby realizing the movement of the housing 100 and ensuring the working performance of the electromagnetic actuator 1000.

[0285] In some embodiments, one of the first component 220 and the second component 210 is a permanent magnet or an electromagnet, and the other is an electromagnetic coil. The electromagnetic coil cooperates with the permanent magnet such that the first component 220 and the second component 210 can form a coupled fit, thereby enabling the working performance of the electromagnetic actuator 1000. That is, the first component 220 is the first excitation component, and the second component is the second excitation component.

[0286] As can be seen from the above structure, for the electromagnetic actuator 1000 according to the embodiment of the present invention, by configuring the housing 100 to include a plurality of sub-housings 101, and connecting the plurality of sub-housings 101 to define an accommodation cavity 130, while reducing the assembly difficulty of the housing 100, it can also reduce the assembly and maintenance difficulties of the first component 220 and the second component 210. At the same time, it can avoid the first component 220 and the second component 210 from colliding with the housing 100 during the assembly process, and ensure the working performance of the first component 220 and the second component 210.

[0287] It can be understood that, compared with the prior art, in the present application, the housing 100 is configured to include a plurality of sub-housings 101, thereby reducing the assembly difficulty of the first component 220 and the second component 210 disposed in the accommodation cavity 130. Moreover, the plurality of sub-housings 101 are also conducive to reducing the assembly difficulty of the housing 100 itself, so that the first component 220 and the second component 210 can be effectively assembled in the housing 100, and to a certain extent, avoid the first component 220 and the second component 210 from colliding with the housing 100 during the assembly process, and ensure the working performance of the first component 220 and the second component 210.

[0288] In some embodiments, as shown in Figure 1 and Figure 2 , the plurality of sub-housings 101 are arranged along the axis. That is to say, the plurality of sub-housings 101 are arranged along the axial direction of the electromagnetic actuator 1000. In this way, the housing 100 can be formed into a plurality of structures arranged along the axial direction of the electromagnetic actuator 1000, reducing the forming difficulty of the housing 100 and the assembly difficulty of the first component 220 and the second component 210 disposed in the housing 100, and improving the assembly efficiency of the electromagnetic actuator 1000.

[0289] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , the plurality of sub-housings 101 include a cylindrical body 1011 with at least one end open and at least one end cap 1012. The end cap 1012 cooperates with the cylindrical body 1011 to form the housing 100, thereby reducing the forming difficulty of the housing 100.

[0290] Among them, by opening at least one end of the cylindrical body 1011, it is convenient to assemble the first component 220 and the second component 210 into the cylindrical body 1011.

[0291] At the same time, the inner surface accuracy of the cylindrical body 1011 and the surface accuracy of the first component 220 need to be strictly controlled to ensure the uniformity of the air gap between the first component 220 and the second component 210, thereby ensuring the working performance of the electromagnetic actuator 1000.

[0292] In some embodiments, as shown in Figure 2As shown, the lower end of the end cap 1012 integrally mounts the mounting bracket 192. The mounting bracket 192 is adapted to be connected to the axle, thereby simplifying the connection mode between the electromagnetic actuator 1000 and the axle, improving the structural reliability, and reducing the assembly process and assembly time of the electromagnetic actuator 1000.

[0293] Among them, the mounting bracket 192 mentioned here can be understood as the lower fork arm of the electromagnetic actuator 1000.

[0294] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 shown, the end cap 1012 is provided at the open part of the cylinder 1011 to ensure the sealing performance of the accommodating cavity 130.

[0295] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 shown, the end cap 1012 is in plug-in fit with the cylinder 1011. In this way, while realizing that the end cap 1012 is provided at the open part of the cylinder 1011, the fixed connection between the end cap 1012 and the cylinder 1011 can also be realized, ensuring the structural stability of the housing 100 and reducing the forming difficulty of the housing 100.

[0296] In some embodiments, as Figure 4 shown, one of the top wall of the end cap 1012 and the lower end of the cylinder 1011 is provided with a clamping groove 1013 and the other is provided with an insertion part 1014, and the insertion part 1014 extends into the clamping groove 1013. To realize the plug-in fit between the end cap 1012 and the cylinder 1011.

[0297] In some embodiments, as Figure 4 shown, the end cap 1012 is connected to the cylinder 1011 by bolts 1016. To further realize the fixed connection between the end cap 1012 and the cylinder 1011, ensure the connection strength between the end cap 1012 and the cylinder 1011, and at the same time make the end cap 1012 and the cylinder 1011 form a detachable connection, ensuring the structural stability and working performance of the housing 100.

[0298] In some embodiments, as Figure 4 shown, the end cap 1012 is positioned with respect to the cylinder 1011 by a positioning pin 1017, thereby positioning the installation direction of the end cap 1012, preventing misinstallation, and reducing the connection difficulty between the end cap 1012 and the cylinder 1011.

[0299] In some embodiments, on the outer peripheral wall of the end cap 1012, there is an end cap connection boss protruding radially outward, and on the cylinder body 1011, there is a corresponding cylinder body connection boss. Both the end cap connection boss and the cylinder body connection boss are provided with connection holes, and fasteners or bolts are inserted into the connection holes to achieve the fixed connection of the end cap 1012 and the cylinder body 1011. By using the connection boss for connection, while increasing the cavity of the end cap 1012 and the cylinder body 1011, the connection stability can also be improved.

[0300] It should be noted that the specifications and quantities of the bolts 1016 and the positioning pins 1017 can be reasonably designed according to the actual mechanical strength requirements.

[0301] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 shown, on the end cap 1012, there is a guide rod 400, and the guide rod 400 is movably matched with the other of the first component 220 and the second component 210 to guide the moving direction of the machine housing 100 with respect to one of the first component 220 and the second component 210. That is to say, one of the first component 220 and the second component 210 is fixedly connected to the machine housing 100, and the other of the first component 220 and the second component 210 is movably matched with the guide rod 400, thereby preventing the machine housing 100 from shifting during movement, that is, ensuring that the machine housing 100 can move along a predetermined direction and guaranteeing the accuracy of the movement of the machine housing 100.

[0302] Through the above settings, when the electromagnetic actuator 1000 is applied to a vehicle, the wheels 2000 can move along a predetermined direction, ensuring the smoothness of the vehicle during driving.

[0303] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 shown, between the guide rod 400 and the other of the first component 220 and the second component 210, there is a guide bearing 840.

[0304] In some embodiments, the first component 220 is fixedly connected to the machine housing 100, and the guide rod 400 is movably matched with the second component 210 to guide the moving direction of the machine housing 100. The verticality and concentricity of the lower end of the second component 210 are determined by the guide rod 400 and the guide bearing 840.

[0305] In some embodiments, such as Figure 2 shown, at the upper end of the cylinder body 1011, there is a bearing installation groove hole for assembling the bearing 170. The bearing 170 positions the upper end of the second component 210, and the verticality and concentricity of the upper end of the second component 210 are determined by the top surface of the cylinder body 1011 and the bearing 170.

[0306] In summary, the main structure of the electromagnetic actuator 1000 in this embodiment is composed of a bearing 170, a cylinder body 1011, a first component 220, a second component 210, a guide bearing 840, and an end cover 1012. Among them, the first component 220 is attached to the inner part of the cylinder body 1011. The bearing 170, the cylinder body 1011, the end cover 1012, and the first component 220 constitute the mover part of the electromagnetic actuator 1000. The inside of the second component 210 is a coil winding, which will form a moving magnetic field when three-phase electricity is applied. This magnetic field acts on the mover part. The second component 210 and the first component 220 generate a mutual force to move the housing 100 up and down. Finally, the electromagnetic actuator 1000 realizes linear motion, and the linear motion of the housing 100 is controlled by adjusting the magnitude and direction of the three-phase electricity to achieve the actual required motion state. And in this embodiment, by reasonably designing the structure between the end cover 1012 and the cylinder body 1011, problems such as the installation of the first component 220 and the second component 210, the assembly of the mounting bracket 192, and the movement and positioning of the housing 100 are solved.

[0307] In a specific example, when assembling the electromagnetic actuator 1000, in the first step, the first component 220 is inserted into the inner surface of the cylinder body 1011 from the bottom of the cylinder body 1011. In the second step, the bearing 170 is assembled with the top surface of the cylinder body 1011. In the third step, the guide bearing 840 is placed into the mounting hole on the lower end surface of the second component 210. Subsequently, the second component 210 is inserted into the cylinder body 1011 from the bottom, and the upper end of the second component 210 is inserted into the bearing 170. Finally, the end cover 1012 is installed upward from the lower end of the cylinder body 1011. The guide rod 400 is inserted into the guide bearing 840, and the extending part 1014 extends into the card slot 1013. The end cover 1012 and the cylinder body 1011 are connected by bolts 1016 and positioning pins 1017. Push and pull the housing 100 to check whether the movement of the housing 100 is smooth. If it is not smooth, it is necessary to check whether the assembly of the guide rod 400 is in place and whether the machining dimensions of each part exceed the standard. Finally, check whether the movement of the electromagnetic actuator 1000 is normal when powered on.

[0308] It should be noted that for the electromagnetic actuator 1000 of this embodiment, the cylinder body 1011 and the end cover 1012 are designed in a split structure, which facilitates the installation of the second component 210 and the first component 220; by integrating the end cover 1012, the guide rod 400, and the mounting bracket 192 into an integrated design, the connection method between the parts of the electromagnetic actuator 1000 is simplified, the assembly process and assembly time are reduced, the structural reliability is improved, and the weight is reduced; by integrating the guide rod 400 on the end cover 1012 and designing an insertion portion 1014 on the upper top surface of the end cover 1012 to be fitted with the inner surface of the cylinder body 1011, the center coincidence of the guide rod 400 and the cylinder body 1011 can be ensured, thereby ensuring the uniformity of the air gap between the second component 210 and the first component 220; by adding a positioning pin 1017 for positioning between the end cover 1012 and the cylinder body 1011, the installation direction of the end cover 1012 is positioned to prevent misinstallation.

[0309] In some embodiments, as shown in Figure 5 、 Figure 6 and Figure 8 multiple sub - shells 101 are arranged circumferentially, and the circumferential direction is substantially perpendicular to the axis. That is to say, the multiple sub - shells 101 are not limited to being arranged along the axis of the electromagnetic actuator 1000, but can also be arranged circumferentially along the electromagnetic actuator 1000. This can also reduce the assembly difficulty of the housing 100, and at the same time reduce the assembly and maintenance difficulties of the first component 220 and the second component 210, avoid the first component 220 and the second component 210 from colliding with the housing 100 during the assembly process, and ensure the working performance of the first component 220 and the second component 210.

[0310] In some embodiments, as shown in Fig. 9 、 Fig.10 、 Fig.11 and Fig.12 multiple sub - shells 101 include a first sub - shell 110 and a second sub - shell 120. The first sub - shell 110 forms a first cavity 115, and the second sub - shell 120 forms a second cavity 125. The first sub - shell 110 and the second sub - shell 120 are arranged opposite to each other so that the first cavity 115 and the second cavity 125 enclose to form a receiving cavity 130. Thereby, the forming difficulty of the receiving cavity 130 is reduced, and it is convenient to arrange the first component 220 and the second component 210 in the receiving cavity 130.

[0311] In some embodiments, as shown in Figure 6 and Figure 8As shown, the first sub - housing 110 and the second sub - housing 120 are rotatably connected. This means that the first sub - housing 110 and the second sub - housing 120 are not only connected but also relatively rotatable. In this way, during the assembly process of the first sub - housing 110 and the second sub - housing 120, the first sub - housing 110 and the second sub - housing 120 can be first rotatably connected. After the connection is in place, at least one of the first sub - housing 110 and the second sub - housing 120 is rotated to form the housing 100, thereby reducing the assembly difficulty of the housing 100.

[0312] That is to say, the housing 100 of this embodiment is circumferentially divided into two parts (the first sub - housing 110 and the second sub - housing 120), and these two parts are rotatably connected. In this way, the first sub - housing 110 and the second sub - housing 120 can rotate around the rotation connection point to open or close the housing 100, reducing the opening and closing difficulty of the housing 100.

[0313] Among them, when the first sub - housing 110 and the second sub - housing 120 rotate to completely open the interior of the housing 100, on the one hand, it is convenient to assemble the first component 220 and the second component 210, on the other hand, it is also convenient to maintain the first component 220 and the second component 210, and at the same time, it can also avoid the first component 220 and the second component 210 from colliding with the housing 100 to a certain extent during the assembly process; when the first sub - housing 110 and the second sub - housing 120 rotate to completely close the interior of the housing 100, the housing 100 can be used to support and protect the first component 220 and the second component 210.

[0314] It should be noted that when the housing 100 is formed as a cylindrical outer shell, through the above - mentioned setting, the housing 100 can be radially divided into the first sub - housing 110 and the second sub - housing 120, so as to reduce the assembly difficulty of the housing 100 and the cooperation difficulty between the first component 220 and the second component 210 and the housing 100.

[0315] In some embodiments, as shown in Fig. 9 、 Fig.10 、 Fig.11 and Fig.12 , the first sub - housing 110 is provided with a first connecting portion 111 protruding therefrom, and the second sub - housing 120 is provided with a second connecting portion 121 protruding therefrom. The first connecting portion 111 and the second connecting portion 121 are rotatably connected. This means that the first sub - housing 110 is provided with a first connecting portion 111 and the first connecting portion 111 protrudes from the first sub - housing 110, and the second sub - housing 120 is provided with a second connecting portion 121 and the second connecting portion 121 protrudes from the second sub - housing 120. In this way, it is convenient to realize the rotational connection between the first connecting portion 111 and the second connecting portion 121, thereby reducing the connection difficulty between the first connecting portion 111 and the second connecting portion 121.

[0316] Meanwhile, after rotatably connecting the first connecting portion 111 and the second connecting portion 121, the rotatable connection between the first sub-housing 110 and the second sub-housing 120 can be achieved. In this way, during the assembly process of the second sub-housing 120 and the first sub-housing 110, the second sub-housing 120 and the first sub-housing 110 can be first rotatably connected. After the connection is in place, at least one of the second sub-housing 120 and the first sub-housing 110 is rotated to form the housing 100, thereby reducing the assembly difficulty of the housing 100.

[0317] In some embodiments, as Figure 5 and Figure 6 shown, the electromagnetic actuator 1000 further includes a rotating shaft 140. Shaft holes are provided on both the first sub-housing 110 and the second sub-housing 120, and the rotating shaft 140 is disposed in the shaft holes to enable relative movement between the first sub-housing 110 and the second sub-housing 120. Thereby, the rotatable connection between the first sub-housing 110 and the second sub-housing 120 is achieved, and the connection difficulty between the first sub-housing 110 and the second sub-housing 120 is reduced.

[0318] In some embodiments, in combination with Figure 5-Figure 12 shown, the first connecting portion 111 includes a plurality of first connecting lugs 1111, and the plurality of first connecting lugs 1111 are spaced apart. The second connecting portion 121 includes a plurality of second connecting lugs 1211, and the plurality of second connecting lugs 1211 are spaced apart. The plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 are staggered. A first connecting hole 1112 is provided on the first connecting lug 1111, and a second connecting hole 1212 is provided on the second connecting lug 1211. The rotating shaft 140 is used to pass through the plurality of first connecting holes 1112 and the plurality of second connecting holes 1212, so as to facilitate the rotatable connection between the first connecting lug 1111 and the second connecting lug 1211 by using the rotating shaft 140, that is, to achieve the rotatable connection between the first sub-housing 110 and the second sub-housing 120.

[0319] It should be noted that the above-mentioned staggered setting can be understood as being in the Figure 5 shown left-right direction, where the first connecting lug 1111 and the second connecting lug 1211 are not directly opposite, so that the plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 are staggered. In this way, after the first sub-housing 110 and the second sub-housing 120 are rotatably butted, the first connecting lug 1111 and the second connecting lug 1211 can be directly opposite in the front-back direction of the housing 100. The front-back direction mentioned here is the same as that in Figure 5The up-down direction and the left-right direction intersect therein, so that the rotating shaft 140 can pass through a plurality of first connecting lugs 1111 and a plurality of second connecting lugs 1211 at the same time, facilitating the connection of the plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 by using the rotating shaft 140, that is, realizing the rotational connection between the first connecting portion 111 and the second connecting portion 121.

[0320] Wherein, Figure 5 The left-right direction shown in can also be understood as the docking direction of the first sub-shell 110 and the second sub-shell 120. That is to say, during the docking process of the first sub-shell 110 and the second sub-shell 120, a plurality of first connecting lugs 1111 and a plurality of second connecting lugs 1211 are arranged in an interleaved manner, so that after the docking process of the first sub-shell 110 and the second sub-shell 120, the first connecting lugs 1111 and the second connecting lugs 1211 can be arranged opposite to each other in the front-back direction of the casing 100. It can be understood that at this time, the shaft holes on the first sub-shell 110 and the second sub-shell 120 are arranged opposite to each other in the front-back direction.

[0321] In summary, the casing 100 of this embodiment is divided into two parts along its circumferential direction, and the first sub-shell 110 and the second sub-shell 120 are connected by using the cooperation of the rotating shaft 140, the first connecting portion 111 and the second connecting portion 121, so that the first sub-shell 110 and the second sub-shell 120 can rotate around the rotating shaft 140 to open or close the casing 100, so that the inside of the casing 100 can be completely opened, which is beneficial to the positioning, installation, fixing, maintenance, etc. of the first component 220 and the second component 210 inside the casing 100, and compared with the end opening of the casing 100, it can also avoid the first component 220 and the second component 210 from colliding with the casing 100 during the assembly process.

[0322] In some embodiments, such as Figure 6 shown, in the axial direction of the casing 100, the end of the first sub-shell 110 and the end of the second sub-shell 120 are rotationally connected. That is to say, one axial end of the first sub-shell 110 is rotationally connected to one axial end of the second sub-shell 120, so as to realize the rotational cooperation between the first sub-shell 110 and the second sub-shell 120 and reduce the assembly difficulty between the first sub-shell 110 and the second sub-shell 120.

[0323] In some embodiments, such as Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the first connecting portion 111 is provided at one axial end of the first sub-housing 110, and the second connecting portion 121 is provided at one axial end of the second sub-housing 120. After the first connecting portion 111 and the second connecting portion 121 are rotatably connected, the rotational cooperation between the first sub-housing 110 and the second sub-housing 120 can be achieved, and the end portions of the first sub-housing 110 and the second sub-housing 120 are rotatably connected.

[0324] With the above arrangement, during the assembly of the housing 100, one end of the first sub-housing 110 and one end of the second sub-housing 120 can be first rotatably connected. After the connection is in place, the first component 220 and the second component 210 are assembled between the first sub-housing 110 and the second sub-housing 120 (as Figure 6 shown), and then the other end of the first sub-housing 110 and the other end of the second sub-housing 120 are driven to rotate towards each other to achieve the mating connection between the first sub-housing 110 and the second sub-housing 120.

[0325] In some other embodiments, as Figure 8 shown, on the circumference of the housing 100, one side of the first sub-housing 110 and one side of the second sub-housing 120 are rotatably connected. That is to say, it is not limited to rotatably connecting the end portions of the first sub-housing 110 and the second sub-housing 120. On the circumference of the housing 100, one side of the first sub-housing 110 and one side of the second sub-housing 120 can also be rotatably connected, and the rotational cooperation between the first sub-housing 110 and the second sub-housing 120 can also be achieved here, reducing the assembly difficulty between the first sub-housing 110 and the second sub-housing 120.

[0326] In some embodiments, as Figure 8 shown, the first connecting portion 111 is provided on one side in the circumferential direction of the first sub-housing 110, and the second connecting portion 121 is provided on one side in the circumferential direction of the second sub-housing 120. After the first connecting portion 111 and the second connecting portion 121 are rotatably connected, the rotational cooperation between the first sub-housing 110 and the second sub-housing 120 can be achieved, and one side of the first sub-housing 110 and one side of the second sub-housing 120 are rotatably connected.

[0327] With the above arrangement, as Figure 8 shown, during the assembly of the housing 100, one side of the first sub-housing 110 in the circumferential direction and one side of the second sub-housing 120 in the circumferential direction can be first rotatably connected. After the connection is in place, the first component 220 and the second component 210 are assembled between the first sub-housing 110 and the second sub-housing 120, and then the other side of the first sub-housing 110 in the circumferential direction and the other side of the second sub-housing 120 in the circumferential direction are driven to rotate towards each other to achieve the mating connection between the first sub-housing 110 and the second sub-housing 120.

[0328] In some embodiments, the first sub-housing 110 and the second sub-housing 120 are detachably engaged. That is to say, the first sub-housing 110 and the second sub-housing 120 are not only rotatably connected, but also form a detachable fit, so that the fixed connection between the first sub-housing 110 and the second sub-housing 120 can be realized, making the relative positions of the first sub-housing 110 and the second sub-housing 120 stable, thereby ensuring the position stability of the housing 100, facilitating the use of the housing 100 to support and protect the first component 220 and the second component 210, extending the service life of the first component 220 and the second component 210, and improving the position stability of the first component 220 and the second component 210.

[0329] At the same time, by setting the first sub-housing 110 and the second sub-housing 120 to be detachably engaged, the difficulty of assembling and disassembling the first sub-housing 110 and the second sub-housing 120 can also be reduced, so as to reduce the difficulty of assembling and disassembling the housing 100 and facilitate the maintenance of the first component 220 and the second component 210.

[0330] In some embodiments, as Figure 6 shown, one of the first sub-housing 110 and the second sub-housing 120 is provided with a third connecting portion 112, and the other is provided with a fourth connecting portion 122 facing the third connecting portion 112. The first fastener 150 connects the third connecting portion 112 and the fourth connecting portion 122 to make the first sub-housing 110 and the second sub-housing 120 detachable. Here, it means that when the first sub-housing 110 is provided with the third connecting portion 112, the second sub-housing 120 is provided with the fourth connecting portion 122; when the second sub-housing 120 is provided with the third connecting portion 112, the first sub-housing 110 is provided with the fourth connecting portion 122. In this way, when the first fastener 150 connects the third connecting portion 112 and the fourth connecting portion 122, the detachable fit between the first sub-housing 110 and the second sub-housing 120 can be realized. While realizing the fixed connection between the first sub-housing 110 and the second sub-housing 120, the relative positions of the first sub-housing 110 and the second sub-housing 120 can also be made stable, thereby ensuring the position stability of the housing 100 and reducing the assembly difficulty of the housing 100.

[0331] In some embodiments, in combination with Fig. 9 、 Fig.10 and Fig.12 shown, the third connecting portion 112 is provided with a third connecting hole 1121, the fourth connecting portion 122 is provided with a fourth connecting hole 1221, and the first fastener 150 connects the third connecting hole 1121 and the fourth connecting hole 1221, thereby realizing the fixed connection between the third connecting portion 112 and the fourth connecting portion 122.

[0332] Optionally, the first fastener 150 can be a fastening bolt, a fastening screw or a rivet.

[0333] Optionally, in combination with Figure 5 、 Figure 6 and Figure 8 As shown, a plurality of third connection portions 112 are provided on the first sub-housing 110, and the plurality of third connection portions 112 are respectively located on the side wall and the end wall of the first sub-housing 110. A plurality of fourth connection portions 122 facing the third connection portions 112 are provided on the second sub-housing 120. In this way, when the first fastener 150 connects the third connection portion 112 and the fourth connection portion 122, the side walls and the end walls of the first sub-housing 110 and the second sub-housing 120 can be detachably fitted, so as to improve the connection strength between the first sub-housing 110 and the second sub-housing 120, thereby making the relative positions of the first sub-housing 110 and the second sub-housing 120 stable.

[0334] In some embodiments, as Figure 7 shown, the housing 100 is provided with a first avoidance through hole 160. The first avoidance through hole 160 communicates with the accommodation cavity 130. The first avoidance through hole 160 is adapted to avoid the central rod 300. A cylindrical bearing 170 is provided in the first avoidance through hole 160. Among them, by providing the first avoidance through hole 160 that avoids the central rod 300 and communicates with the accommodation cavity 130, it can be ensured that the central rod 300 can extend into the accommodation cavity 130 through the first avoidance through hole 160; by providing the cylindrical bearing 170 in the first avoidance through hole 160, when the central rod 300 moves relative to the accommodation cavity 130, the bearing 170 can be used to guide the central rod 300, so as to ensure the position accuracy of the central rod 300 during movement. At the same time, it can also prevent the central rod 300 from contacting the hole wall of the first avoidance through hole 160 during the movement process, thereby avoiding interference between the central rod 300 and the hole wall of the first avoidance through hole 160, so that the central rod 300 can accurately move relative to the accommodation cavity 130.

[0335] At the same time, by providing the bearing 170, it is more beneficial to ensure that the air gap between the permanent magnet and the coil is maintained within a reasonable designed range, ensure the stability of the system structure, and improve the anti-side-suction ability of the system.

[0336] It should be noted that since the first avoidance through hole 160 is formed on the housing 100, during the machining process of the first avoidance through hole 160, technical problems such as low smoothness of the hole wall of the first avoidance through hole 160 and poor position accuracy of the first avoidance through hole 160 are likely to occur. At this time, if the central rod 300 is directly fitted with the first avoidance through hole 160, problems such as interference between the central rod 300 and the first avoidance through hole 160 during the movement process are likely to occur. Therefore, in this embodiment, a cylindrical bearing 170 is provided in the first avoidance through hole 160. In this way, while using the bearing 170 to guide the central rod 300, interference between the central rod 300 and the hole wall of the first avoidance through hole 160 during the movement process can be avoided, so as to ensure the position accuracy of the central rod 300 during movement.

[0337] It should also be noted that the movement of the central rod 300 relative to the accommodation cavity 130 described above can be translation or rotation.

[0338] Optionally, the bearing 170 is detachably arranged in the first avoidance through hole 160, which is convenient for separately machining the bearing 170 to ensure the structural accuracy of the bearing 170, thereby ensuring the guiding performance of the bearing 170.

[0339] In some embodiments, such as Fig.15 and Fig.16 shown, a convex portion 171 is provided on the outer periphery of the bearing 170, and the convex portion 171 is fitted and connected in the first avoidance through hole 160 to realize the fitting connection between the bearing 170 and the first avoidance through hole 160, so as to facilitate guiding the central rod 300 by using the bearing 170, and the structure of the bearing 170 is simple and the installation is convenient. At the same time, there is no need to additionally increase an installation and fixing structure to fix the bearing 170.

[0340] In some embodiments, such as Figure 6 and Fig.14 shown, a second component 210 is provided on the central rod 300. In this way, when the central rod 300 extends into the accommodation cavity 130, the second component 210 can be arranged in the accommodation cavity 130, so that the second component 210 can cooperate with the first component 220, thereby ensuring the working performance of the electromagnetic actuator 1000.

[0341] At the same time, by providing the second component 210 on the central rod 300 and arranging the first component 220 on the housing 100, an electromagnetic scheme with a permanent magnet on the outside and a coil assembly on the inside can also be formed. Under the condition of limited space constraints, a larger air gap diameter can be obtained, so as to provide a larger active thrust.

[0342] It should be noted that since the housing 100 of this embodiment is circumferentially divided into a first sub-housing 110 and a second sub-housing 120, when the housing 100 is used on the electromagnetic actuator 1000, since the second component 210 needs to be divided into two halves when it is provided on the first sub-housing 110 and the second sub-housing 120, magnetic induction lines cannot be generated. Therefore, when the housing 100 is used on the electromagnetic actuator 1000, the second component 210 is provided on the central rod 300, and the first component 220 is provided on the first sub-housing 110 and the second sub-housing 120 and is divided into two parts; when the housing 100 is used on a rotating motor, since the direction of the second component 210 is different, the second component 210 can be provided on the first sub-housing 110 and the second sub-housing 120 and divided into two parts, or it can be provided on the central rod 300.

[0343] In some embodiments, as shown in Figure 6 、 Fig. 9 and Fig.11 the first sub-housing 110 is provided with a first avoidance groove 113, and the second sub-housing 120 is provided with a second avoidance groove 123. The first avoidance groove 113 and the second avoidance groove 123 cooperate to define a first avoidance through hole 160. In this way, while forming the first avoidance through hole 160 communicating with the accommodation cavity 130 on the housing 100, the forming difficulty of the first avoidance through hole 160 can be reduced, and the matching difficulty between the bearing 170, the central rod 300 and the first avoidance through hole 160 can be reduced, improving the assembly efficiency of the housing 100.

[0344] At the same time, through the above settings, it is also convenient to assemble the second component 210 on the central rod 300 into the accommodation cavity 130.

[0345] In summary, it can be understood that after the housing 100 is circumferentially divided into a first sub-housing 110 and a second sub-housing 120, the mid-plane of the housing 100 is a plane passing through the axis of the bearing 170.

[0346] It should be noted that for a cylindrical motor housing, this mid-plane can divide the cylindrical motor housing into two left-right symmetric parts; for other-shaped motor housings (such as square, pentagonal, etc.), this mid-plane can divide the housing 100 into two parts but not symmetrically.

[0347] That is to say, when the housing 100 is formed as a cylindrical motor housing, the first sub-housing 110 and the second sub-housing 120 are generally symmetric in structure; when the housing 100 is formed as other-shaped motor housings, the first sub-housing 110 and the second sub-housing 120 are generally asymmetric in structure.

[0348] In some embodiments, as shown in Figure 6 and Figure 7As shown, the housing 100 further includes a guide rod 400, and the other of the first component 220 and the second component 210 cooperates with the guide rod 400. This avoids the deviation of the other of the first component 220 and the second component 210 during movement, that is, ensures that the other of the first component 220 and the second component 210 can perform relative movement along a predetermined direction, guarantees the accuracy of the movement of the other of the first component 220 and the second component 210, and to a certain extent, ensures that the relative axial distance between the housing 100 and the other of the first component 220 and the second component 210 remains unchanged during their relative movement.

[0349] In some embodiments, as Figure 7 shown, one end of the central rod 300 located in the accommodation cavity 130 is provided with a guide hole 310, and the guide rod 400 is movably engaged with the guide hole 310, so as to facilitate guiding the movement direction of the central rod 300 by the guide rod 400 and guarantee the accuracy of the movement of the central rod 300.

[0350] In some embodiments, as Figure 7 shown, the guide rod 400 is arranged on the rotating shaft 140. Here, it means that when the ends of the first sub-housing 110 and the second sub-housing 120 are rotatably connected, the guide rod 400 is arranged on the rotating shaft 140 to realize the fixed connection between the end of the guide rod 400 and the housing 100, reduce the cooperation difficulty between the guide rod 400 and the housing 100, and thus facilitate supporting the guide rod 400 by the housing 100 and improve the position stability of the guide rod 400.

[0351] In some embodiments, in combination with Figure 7 and Fig.13 shown, the guide rod 400 is provided with a through hole 411, and the rotating shaft 140 passes through the through hole 411. Thereby, the guide rod 400 is arranged on the rotating shaft 140.

[0352] In some embodiments, as Fig.13 shown, the end of the guide rod 400 is provided with a mounting boss 410, and the mounting boss 410 is provided with a through hole 411, and the rotating shaft 140 passes through the through hole 411 to realize the mating connection between the rotating shaft 140 and the guide rod 400.

[0353] In summary, the first sub-shell 110, the second sub-shell 120, and the guide rod 400 of this embodiment are connected together through the rotating shaft 140, and the three can rotate relative to each other around the rotating shaft 140. When specifically assembling the housing 100, first pass the rotating shaft 140 through the ends of multiple first connecting lugs 1111, multiple second connecting lugs 1211, and the guide rod 400 in sequence to achieve the rotational cooperation of the first sub-shell 110, the second sub-shell 120, and the guide rod 400. Subsequently, sleeved the bearing 170 on the central rod 300, and sleeved the central rod 300 on the guide rod 400. Then, rotate the guide rod 400, the bearing 170, and the central rod 300 around the rotating shaft 140 to make it close to one of the first sub-shell 110 or the second sub-shell 120, and ensure that the bearing 170 is fitted in the third avoidance groove 114 or the fourth avoidance groove 124. Then, control the other of the first sub-shell 110 or the second sub-shell 120 to rotate around the rotating shaft 140 to make the first sub-shell 110 and the second sub-shell 120 fit together. Finally, use the first fastener 150 to connect the first sub-shell 110 and the second sub-shell 120 to achieve the fixed connection between the first sub-shell 110 and the second sub-shell 120. During the above connection process, it is possible to completely avoid the contact between the second component 210 on the central rod 300 and the first component 220 on the first sub-shell 110 and the second sub-shell 120, thereby avoiding the damage of the first component 220 and the second component 210 and extending the service life of the first component 220 and the second component 210.

[0354] In addition, through the above settings, the guide rod 400 and the housing 100 can form a split-type detachable design. Without losing the coaxiality between the guide rod 400 and the housing 100, it is more conducive to the installation and fixation of the first component 220 on the inner peripheral surface of the housing 100. At the same time, it is also convenient to separately process the guide rod 400 to ensure the smoothness of the surface of the guide rod 400, thereby ensuring the guiding performance of the guide rod 400.

[0355] In some embodiments, as Figure 6 、 Figure 7 and Figure 8 shown, at least part of the structure of the guide rod 400 extends out of the accommodation cavity 130, and the through hole 411 is provided on the part of the structure of the guide rod 400 that extends out of the accommodation cavity 130. That is to say, the end of the guide rod 400 extends out of the first sub-shell 110 and the second sub-shell 120, and the end of the guide rod 400 is connected to the first sub-shell 110 and the second sub-shell 120. To achieve the fixed connection between the guide rod 400 and the housing 100, thereby facilitating the use of the housing 100 to support the guide rod 400, improving the position stability of the guide rod 400, ensuring the working performance of the guide rod 400, and facilitating the use of the guide rod 400 to guide the moving direction of the central rod 300.

[0356] Meanwhile, by extending the end of the guide rod 400 out of the first sub-housing 110 and the second sub-housing 120, the connection between the guide rod 400 and the housing 100 can be realized outside the housing 100, so as to reduce the connection difficulty between the guide rod 400 and the housing 100, that is, reduce the mating difficulty of the guide rod 400.

[0357] In some embodiments, as Figure 7 shown, the housing 100 is provided with a second avoidance through-hole 161, the second avoidance through-hole 161 communicates with the accommodation cavity 130, and the second avoidance through-hole 161 is used to avoid the guide rod 400, so that the end of the guide rod 400 can extend out of the first sub-housing 110 and the second sub-housing 120 and be connected to the first sub-housing 110 and the second sub-housing 120, so as to reduce the connection difficulty between the guide rod 400 and the housing 100.

[0358] Optionally, in combination with Figure 6 , Figure 8 , Fig.10 and Fig.12 shown, the first sub-housing 110 is provided with a third avoidance groove 114, the second sub-housing 120 is provided with a fourth avoidance groove 124, and the third avoidance groove 114 and the fourth avoidance groove 124 cooperate to define the second avoidance through-hole 161. In this way, while forming the second avoidance through-hole 161 communicating with the accommodation cavity 130 on the housing 100, the forming difficulty of the second avoidance through-hole 161 and the mating difficulty between the guide rod 400 and the second avoidance through-hole 161 can be reduced, and the assembly efficiency of the housing 100 can be improved.

[0359] Optionally, as Figure 7 and Fig.13 shown, the guide rod 400 is provided with a guide protrusion 430, and the guide protrusion 430 is fitted and connected in the second avoidance through-hole 161 to realize the mating connection between the guide rod 400 and the second avoidance through-hole 161 and position the guide rod 400 to ensure the position stability of the guide rod 400.

[0360] In other embodiments, as Figure 8 shown, in the circumferential direction of the housing 100, one side of the first sub-housing 110 and one side of the second sub-housing 120 are rotatably connected, and the end of the guide rod 400 extends to one side of the axial end of the first sub-housing 110 and the second sub-housing 120 and is connected to the first sub-housing 110 and the second sub-housing 120. Here, it means that when one side of the first sub-housing 110 and one side of the second sub-housing 120 are rotatably connected, the end of the guide rod 400 is connected to the axial ends of the first sub-housing 110 and the second sub-housing 120. In this way, while the first sub-housing 110 and the second sub-housing 120 form a rotatable connection, it can also ensure that the guide rod 400 can effectively cooperate with the central rod 300, so as to facilitate guiding the moving direction of the central rod 300 by using the guide rod 400.

[0361] In some embodiments, as Figure 8 shown, in the circumferential direction of the housing 100, one side of the first sub-housing 110 and one side of the second sub-housing 120 are rotatably connected. An installation plate 420 is provided at the end of the guide rod 400. A fifth connection hole 421 is provided on the installation plate 420. Sixth connection holes 180 facing the fifth connection hole 421 are provided on both the first sub-housing 110 and the second sub-housing 120. A second fastener connects the fifth connection hole 421 and the sixth connection hole 180, so that the guide rod 400 is fixedly connected to the first sub-housing 110 and the second sub-housing 120, thereby facilitating the use of the housing 100 to support the guide rod 400, improving the position stability of the guide rod 400, and ensuring the working performance of the guide rod 400.

[0362] Optionally, the second fastener can be a fastening bolt, a fastening screw or a rivet.

[0363] In summary, the first sub-housing 110 and the second sub-housing 120 of this embodiment are connected together by a rotating shaft 140, and the two can rotate relative to each other around the rotating shaft 140. When the housing 100 is specifically assembled, first, the rotating shaft 140 is sequentially passed through a plurality of first connecting lugs 1111 and a plurality of second connecting lugs 1211 to realize the rotational cooperation between the first sub-housing 110 and the second sub-housing 120. Subsequently, the central rod 300 is arranged in one of the first sub-housing 110 and the second sub-housing 120, the bearing 170 is sleeved on the central rod 300, and the central rod 300 is sleeved on the guide rod 400. Then, the other of the first sub-housing 110 and the second sub-housing 120 is rotated around the rotating shaft 140 to make it close to one of the first sub-housing 110 or the second sub-housing 120, and it is ensured that the bearing 170 is fitted in the third avoidance groove 114 and the fourth avoidance groove 124 to make the first sub-housing 110 and the second sub-housing 120 fit together. Finally, the first sub-housing 110 and the second sub-housing 120 are connected by the first fastener 150, and the guide rod 400 is connected by the second fastener to realize the fixed connection between the first sub-housing 110 and the second sub-housing 120. During the above connection process, it is also possible to completely avoid the contact between the second component 210 on the central rod 300 and the first component 220 on the first sub-housing 110 and the second sub-housing 120, thereby avoiding damage to the first component 220 and the second component 210 and prolonging the service life of the first component 220 and the second component 210.

[0364] In some embodiments, the electromagnetic actuator 1000 of this embodiment is formed as a cylindrical linear motor. The structure of the cylindrical linear motor is relatively closed, has good sealing performance and no unilateral magnetic pull force, so as to ensure the working performance of the electromagnetic actuator 1000.

[0365] It should be noted that when the electromagnetic actuator 1000 is formed as a cylindrical linear motor, both the first sub-housing 110 and the second sub-housing 120 of the housing 100 are formed as semi-cylindrical shapes, so that the first sub-housing 110 and the second sub-housing 120 can cooperate to form a complete cylindrical motor housing.

[0366] In some embodiments, as Figure 7 shown, a spring 600 is provided on the electromagnetic actuator 1000. The spring 600 is used to provide part of the damping force and bear part of the vibration shock, so as to improve the working performance of the electromagnetic actuator 1000, thereby ensuring the comfort of the vehicle.

[0367] Optionally, as Figure 7 shown, an upper support 500 and a mounting seat 191 are further provided on the electromagnetic actuator 1000. The upper support 500 is connected to the side of the central rod 300 away from the receiving cavity 130, and the mounting seat 191 is connected to the outer peripheral wall of the housing 100. A receiving space for accommodating the spring 600 is formed between the upper support 500 and the mounting seat 191. The spring 600 is placed in the receiving space to fix the spring 600 by the cooperation of the upper support 500 and the mounting seat 191. In this way, when the electromagnetic actuator 1000 is applied to the suspension system 10000 of the vehicle, when the vehicle is subjected to road excitation and the central rod 300 and the housing 100 move relative to each other, it is convenient to use the spring 600 to achieve buffering and vibration absorption. At the same time, the spring 600 can also play a certain damping role, improving the vibration damping effect of the electromagnetic actuator 1000, thereby improving the comfort of the vehicle.

[0368] In some embodiments, as Figure 7 shown, the spring 600 is arranged between the upper support 500 and the mounting seat 191, and the upper end of the spring 600 abuts against the upper support 500, and the lower end of the spring 600 abuts against the mounting seat 191. In this way, during the relative movement of the central rod 300 and the housing 100, the spring 600 can be compressed or stretched to use the spring 600 to provide part of the damping force and bear part of the vibration shock, improving the comfort of the vehicle.

[0369] In some embodiments, as Figure 7 shown, a bushing 700 is provided on the side of the central rod 300 away from the receiving cavity 130. The bushing 700 is connected to the upper support 500, and buffer blocks 800 are provided on the opposite side surfaces of the upper support 500 and the mounting seat 191. The spring 600 is arranged between the two buffer blocks 800.

[0370] In some embodiments, in combination with Fig.17 , Fig.18 , Fig.19 and Fig. 20As shown, the first component 220 is connected to the housing 100. An elastic limiting member 1015 is provided between the housing 100 and the second component 210. The elastic limiting member 1015 abuts against the housing 100 and the second component 210 respectively. This ensures that during the operation of the electromagnetic actuator 1000, it can buffer the vibration of the second component 210, extend the service life of the second component 210, and reduce the noise generated when the electromagnetic actuator 1000 is working.

[0371] In some embodiments, the elastic limiting member 1015 is formed as a spring 600 and / or a buffer pad. Here, it means that the elastic limiting member 1015 is formed as a spring 600; or, the elastic limiting member 1015 is formed as a buffer pad; or, the elastic limiting member 1015 is formed as a spring 600 and a buffer pad, so as to facilitate the elastic limiting member 1015 to buffer the vibration of the second component 210, extend the service life of the second component 210, and reduce the noise generated when the electromagnetic actuator 1000 is working.

[0372] It should be noted that the specific implementation form of the elastic limiting member 1015 in this embodiment includes but is not limited to forms of elastic members such as rubber pads, polyurethane pads, helical springs, leaf springs, coil springs, etc. There are also no restrictions on the number and layering method of the elastic limiting member 1015 in this embodiment. For example, forms such as using multiple buffer pads or arranging multiple springs circumferentially all belong to the scope of embodiments that can be realized in this embodiment.

[0373] In some embodiments, as Fig. 20 shown, the elastic limiting member 1015 is a helical spring. The helical spring is arranged between the housing 100 and the second component 210. In actual use, in order to buffer the movement of the second component 210, it is necessary to ensure that the helical spring is in a compressed state after assembly. Therefore, the press-fitting of the end cover 1012 can be used to ensure the compression amount of the helical spring.

[0374] In some embodiments, in combination with Fig.17 、 Fig.10 and Fig. 20 shown, the second component 210 is located inside the housing 100 and is distributed circumferentially along the inner radial direction of the housing 100. The elastic limiting member 1015 is located below the second component 210 and above the end cover 1012.

[0375] Among them, the second component 210 consists of multiple magnet components. One layer of magnets forms a complete ring. All layers of magnets are pasted on the inner wall of the housing 100. At the bottom of the lowermost layer of magnets, an elastic limiting member 1015 is provided. The lower end of the elastic limiting member 1015 is connected to the top of the stop of the end cover 1012. Because the elastic limiting member 1015 has a certain elasticity, it is ensured that during the operation of the electromagnetic actuator 1000, the elastic limiting member 1015 can buffer the vibration of the magnets.

[0376] It should be noted that the size of the elastic limiting member 1015 is not fixed and can be adjusted according to the size of the electromagnetic actuator 1000, which has the advantage of high adaptability.

[0377] At the same time, the elastic limiting member 1015 of this embodiment can integrate the function of the sealing module and play a role in sealing the gap between the end cover 1012 and the housing 100.

[0378] In a specific example, during the assembly process, first apply glue on the outer surface of the second component 210, and then axially layer the second component 210 into the housing 100 along the axis of the electromagnetic actuator 1000. After the assembly of the lowermost second component 210 is completed, the elastic limiting member 1015 is assembled, and finally the end cover 1012 is assembled. When the elastic limiting member 1015 is a spiral spring, the preloading of the spiral spring can be completed.

[0379] It should also be noted that the preloading force of the spiral spring in this embodiment should not be too large to avoid exerting too much pressure on the magnet. During the implementation process, the preloading force can be controlled by the height of the extending portion 1014 on the end cover 1012.

[0380] In some embodiments, two adjacent sub-housings 101 among the plurality of sub-housings 101 can be rotatably connected. Here, it means that regardless of whether the plurality of sub-housings 101 are oppositely arranged in the circumferential direction or the axial direction of the housing 100, two adjacent sub-housings 101 are rotatably connected to further reduce the assembly difficulty of the housing 100, and at the same time reduce the assembly difficulty of the first component 220 and the second component 210, and can avoid the first component 220 and the second component 210 from colliding with the housing 100 during the assembly process to a certain extent.

[0381] In some embodiments, the plurality of sub-housings 101 are detachably connected. In this way, the fixed connection of the plurality of sub-housings 101 can be realized, making the relative positions of the plurality of sub-housings 101 stable, thereby ensuring the position stability of the housing 100, facilitating the use of the housing 100 to support and protect the first component 220 and the second component 210, so as to extend the service life of the first component 220 and the second component 210, and improve the position stability of the first component 220 and the second component 210.

[0382] At the same time, by setting the plurality of sub-housings 101 to be detachably engaged, the assembly and disassembly difficulty of the plurality of sub-housings 101 can also be reduced, so as to reduce the assembly and disassembly difficulty of the housing 100 and facilitate the maintenance of the first component 220 and the second component 210.

[0383] In some embodiments, in combination with Figure 20-26As shown, the electromagnetic actuator 1000 includes a central rod 300, and a partial structure of the central rod 300 extends out of the housing 100. This facilitates the fixed connection between the central rod 300 and external components, reduces the connection difficulty between the central rod 300 and external components, and thus ensures the working performance of the electromagnetic actuator.

[0384] In some embodiments, as shown in Fig.21 and Fig. 22 the second component 210 includes an iron core assembly 211 and a winding assembly 212. The iron core assembly 211 is disposed on the central rod 300, and the winding assembly 212 is disposed on the iron core assembly 211. This facilitates the support of the iron core assembly 211 and the winding assembly 212 by the central rod 300, improves the position stability of the iron core assembly 211 and the winding assembly 212, and at the same time enables the iron core assembly 211 and the winding assembly 212 to cooperate with the first component 220, ensuring the working performance of the electromagnetic actuator 1000.

[0385] In summary, the second component 210 is disposed on the central rod 300, the first component 220 is disposed on the housing 100, and the first component 210 and the second component 220 are coupled and cooperated so that the central rod 300 and the housing 100 can move relative to each other, thereby ensuring the working performance of the electromagnetic actuator 1000.

[0386] In some embodiments, as shown in Fig. 22 and Fig.23 the central rod 300 is provided with a wire passing channel 330, and the connection wire 2121 of the winding assembly 212 passes through the wire passing channel 330 and extends out of the housing 100. This realizes leading the connection wire 2121 of the winding assembly 212 from the inside of the housing 100 to the outside of the housing 100, facilitating the leading out of the connection wire 2121 of the winding assembly 212, reducing the electrical connection difficulty of the winding assembly 212, and at the same time protecting the connection wire 2121 by the central rod 300, prolonging the service life of the connection wire 2121, and improving the use safety of the connection wire 2121.

[0387] In some embodiments, the end of the electromagnetic actuator 1000 has a quick-change connector, which can realize the quick plugging and unplugging of the connection wire 2121 and the electrical control component.

[0388] In some embodiments, as shown in Fig. 22 , Fig.23 and Fig.26 the central rod 300 is provided with a wire outlet device 230 inside, and the wire passing channel 330 is arranged inside the wire outlet device 230, thus realizing the arrangement of the wire passing channel 330 inside the central rod 300 and reducing the forming difficulty of the wire passing channel 330.

[0389] It should be noted that the overall structure of the electromagnetic actuator 1000 in this embodiment is based on a traditional hydraulic damping shock absorber, where the middle damper is replaced by a linear motor. According to the structural composition of the electromagnetic actuator 1000, it mainly includes a first component 220 (rotor component), a second component 210 (stator component), and an upper support 500. The first component 220 and the second component 210 form a linear motor, and the connection line 2121 of the second component 210 is led to the outside of the housing 100 through the central rod 300.

[0390] In a specific example, the second component 210 is a part of the stator component. The stator component is arranged inside the entire electromagnetic actuator 1000 and includes a connection line 2121, a wire outlet device 230, a detection module 900, a central rod 300, a first limiting member 380, an iron core assembly 211, a winding assembly 212, a guiding bearing 840, a limiting nut 850, a bearing 170, and an assembly nut 830. Among them, the connection line 2121, the limiting nut 850, the guiding bearing 840, the first limiting member 380, the wire outlet device 230, the bearing 170, and the assembly nut 830 are all assembled on the central rod 300 to jointly form a central component, integrating multiple functions such as limiting, positioning, anti-rotation, heat dissipation, guiding, and wire outlet. The iron core assembly 211 and the winding assembly 212 form the second component 210.

[0391] In some embodiments, both the iron core assembly 211 and the winding assembly 212 are circular rings. The second component 210 is stacked by a plurality of iron core assemblies 211 and winding assemblies 212 with one layer of winding assembly 212 stacked on one layer of iron core assembly 211 and sleeved on the central rod 300, and finally forms a cylindrical shape and is fixed on the central rod 300 by the limiting nut 850. Such a design facilitates the manufacture of the iron core assembly 211 and the winding of the winding assembly 212. The detection module 900 is fixed on the assembly groove 950 of the central rod 300, which plays a role in accurately positioning the relative position between the rotor component and the stator component, so as to achieve accurate control. The connection line 2121 is fixed on the central rod 300 through the wire outlet device 230.

[0392] In some embodiments, as Fig.24 shown, the outer peripheral wall of the iron core assembly 211 is provided with a first reinforcing rib 2012, and a wire routing channel is arranged inside the first reinforcing rib 2012. The wire routing channel is used to guide the connection lines 2121 of different phases of the winding assembly 212 to the wire passing channel 330 of the central rod 300. Here, it means that the wire routing channel is arranged inside the first reinforcing rib 2012. Using the wire routing channel facilitates the extraction of the connection lines 2121 of the winding assembly 212 and reduces the electrical connection difficulty of the winding assembly 212.

[0393] At the same time, by setting the first reinforcing rib 2012, the forming difficulty of the wire routing channel can be reduced, and the wire routing channel can also limit the position of the connection line 2121, improving the position stability of the connection line 2121.

[0394] In some embodiments, the first reinforcing rib 2012 protrudes towards the outer periphery of the iron core assembly 211 to form a wiring channel on the side of the first reinforcing rib 2012 facing the inner periphery of the iron core assembly 211.

[0395] In some embodiments, as Fig.24 shown, a plurality of notches 2019 and a number of first reinforcing ribs 2012 that can restrict the wire outlet direction are evenly distributed on the circumference of the iron core assembly 211, and the connecting wires 2121 of different phases of the winding assembly 212 exit from the designated notches 2019 along the wiring channels therein.

[0396] At the same time, according to the principle that the same-phase wires of the three-phase wires need to be connected together, the connecting wires 2121 of the same phase of the winding assembly 212 exit from the same notch 2019, so that the connecting wires 2121 of the same phase can be connected together from top to bottom on the outside of the iron core assembly 211 (as Fig.24 shown), the tool operation space is not restricted, and problems can be easily and intuitively found during subsequent maintenance, reducing the maintenance cost.

[0397] It should be noted that since the notch 2019 restricts the wire outlet direction, and at the same time, there is a cylindrical pin between the iron core assembly 211 and the center rod 300 to restrict the rotation of the iron core assembly 211 around the center rod 300, the connecting wires 2121 of the winding assembly 212 are relatively fixed, with small position deviation and reliable connection.

[0398] In some embodiments, in combination with Fig. 22 , Fig.23 , Fig.24 and Fig.25 shown, the three connecting wires 2121 respectively pass through three wire passing channels 330 on the wire outlet device 230, and the three outlets of the three wire passing channels 330 are evenly distributed in the circumferential direction. Three wire outlet ports 311 are provided on the center rod 300. The three outlets of the wire passing channels 330, the three wire outlet ports 311, and the three notches 2019 correspond one by one. During assembly, the wire outlet device 230 is assembled onto the center rod 300, and the three connecting wires 2121 pass through the wire outlet device 230, the wire outlet ports 311 and are connected to the winding assembly 212 together.

[0399] Through the above settings, the connecting wires 2121 exit from the outside of the iron core assembly 211 and then penetrate into the inside of the center rod 300 and pass through the wire passing channels 330 to reach the outside of the machine shell 100. The wire outlet is fixed throughout the process. Among them, the wire passing channels 330 play a role in fixing and protecting the connecting wires 2121, and well solve the problem of the risk of extrusion and scratching in the prior art here.

[0400] In some embodiments, as Fig. 22As shown, a first limiting member 380 is sleeved above the central rod 300, and the first limiting member 380 and the outlet of the central rod 300 are jointly fixed to the connection line 2121.

[0401] In some embodiments, the first limiting member 380 is made of rubber, which can buffer the impact of surrounding components on the connection line 2121 under extreme working conditions, thereby playing a role in protecting the connection line 2121 and ensuring the reliability of the electrical system.

[0402] In this embodiment, the mover assembly of the electromagnetic actuator 1000 is arranged on the outer side of the whole structure, including: a bearing 170, a housing 100, a first component 220, a second limiting member 390, a guide rod 400 and a mounting bracket 192. Among them, the mounting bracket 192 is assembled to the wheel end and is connected to the housing 100 by a plurality of bolts, jointly forming a closed operating environment inside the electromagnetic actuator 1000. The guide rod 400 plays a guiding role. The second limiting member 390 is sleeved on the guide rod 400 and can buffer the impact of the first component 220 on the second component 210 under extreme working conditions, thereby well protecting the second component 210. The first components 220 are evenly distributed inside the housing 100 and are used to provide a fixed magnetic field. The housing 100 mainly plays a protective role. The local convex features (such as: a mounting seat 191 and a second reinforcing rib 195) on the housing 100 mainly play the role of supporting the spring 600 and overall heat dissipation.

[0403] Through the above settings, during the movement of the electromagnetic actuator 1000, the first component 220 moves axially up and down along the center line through the bearing 170, the guide bearing 840, the housing 100 and the mounting bracket 192 and the central rod 300. Since the inside of the whole housing 100 is sealed and the housing 100 is moving, when the winding assembly 212 exits the line, it needs to pass through the central rod 300 to the outside of the housing 100. There is relative movement between the outer side of the upper end of the central rod 300 and the bearing 170, and a guide bearing 840 is embedded inside the lower end of the central rod 300, and there is relative movement between the guide bearing 840 and the mounting bracket 192. Therefore, as Fig.24 shown, the winding assembly 212 is sleeved below the central rod 300 and the winding assembly 212 exits the line from the outside, avoiding the relative movement area between the bearing 170 below the central rod 300 and the mounting bracket 192. The connection line 2121 passes through the central rod 300 and reaches the outside of the housing 100 through the wire outlet device 230, avoiding the relative movement area between the upper part of the central rod 300 and the bearing 170. Such a design avoids the connection line 2121 being squeezed or scratched during operation.

[0404] In some embodiments, a tower top is provided above the electromagnetic actuator 1000. The tower top includes an upper support 500, an assembly nut 830, a spring 600, a dust cover 820, and a cooling structure 810. The electromagnetic actuator 1000 is assembled to the tower top by mating the first threaded section 831 on the center rod 300 with the assembly nut 830. The tower top is fixed to the vehicle body. The center rod 300 passes through the middle of the upper support 500, and the connection line 2121 also passes through the vehicle body to reach the front compartment and is mated with the electric control end through a quick-change connector, thereby connecting the motor electric control and finally realizing the control of the electromagnetic shock absorber.

[0405] Among them, the spring 600 can buffer the impact of the road surface. The dust cover 820 can prevent dust from entering the interior of the electromagnetic actuator 1000. The upper support 500 cooperates with the vehicle body to fix one end of the electromagnetic actuator 1000 to the vehicle body. The cooling structure 810 can perform heat exchange circulation with the coolant in the center rod 300 to reduce the temperature of the coolant.

[0406] In some embodiments, after the winding assembly 212 and the iron core assembly 211 are assembled to the center rod 300, the limit nut 850 and the second threaded section 851 cooperate to threadedly assemble the iron core assembly 211 onto the center rod 300. Such a design ensures that the entire iron core assembly 211 is fixed to the center rod 300 in the designed state.

[0407] In summary, for the wire outlet structure of the electromagnetic actuator 1000 in this embodiment, by utilizing the relative relationship of the surrounding components, it cleverly designs to solve the problem of difficult wire outlet, and has advantages such as safety and reliability, convenient disassembly and assembly, and compact space design.

[0408] In some embodiments, in combination with Figure 21-Figure 25 As shown, the center rod 300 is provided with a first anti-rotation portion 370, and the housing 100 is provided with a second anti-rotation portion. The first anti-rotation portion 370 and the second anti-rotation portion cooperate to limit the rotational freedom of the center rod 300. Thereby, relatively large rotation between the center rod 300 and the housing 100 is avoided, so as to ensure that the center rod 300 and the housing 100 can effectively move relative to each other and ensure the working performance of the electromagnetic actuator 1000.

[0409] In some embodiments, in combination with Figure 21-Figure 25 As shown, the first anti-rotation portion 370 is a long slot extending along the axial direction of the center rod 300, and the second anti-rotation portion is fixed to the housing 100 and extends into the first anti-rotation portion 370. Thereby, the purpose of limiting the rotational freedom of the center rod 300 by the cooperation of the first anti-rotation portion 370 and the second anti-rotation portion is achieved, avoiding relative rotation between the center rod 300 and the housing 100, and ensuring the working performance of the electromagnetic actuator 1000.

[0410] In some embodiments, as Fig.21As shown, an anti-rotation hole 193 is provided on the housing 100. The second anti-rotation part is an anti-rotation post, and the anti-rotation post passes through the anti-rotation hole 193 and extends into the first anti-rotation part 370 to realize the cooperation between the first anti-rotation part 370 and the second anti-rotation part, facilitating the restriction of the rotational freedom of the central rod 300.

[0411] In some embodiments, the anti-rotation post is fixed to the anti-rotation hole 193 to ensure the position stability of the anti-rotation post, thereby facilitating the use of the cooperation between the first anti-rotation part 370 and the second anti-rotation part to restrict the rotational freedom of the central rod 300.

[0412] In some embodiments, in combination Figure 27-Figure 35 As shown, the winding assembly 212 has a first lead-out head 2018, and at least part of the structure of the first lead-out head 2018 is located between the iron core assembly 211 and the housing 100. To realize lead-out from the outside of the winding assembly 212, reducing the lead-out difficulty of the winding assembly 212 and the layout difficulty of the connection line 2121.

[0413] In addition, the above setting also creates space inside the iron core assembly 211, facilitating the cooling design.

[0414] In some embodiments, the first lead-out head 2018 is connected to the connection line 2121 to ensure the working performance of the winding assembly 212.

[0415] It should be noted that the electromagnetic actuator 1000 of this embodiment belongs to the suspension system 10000 of the vehicle, replaces the traditional vehicle shock absorber, and is installed at the position of the traditional vehicle shock absorber. Its main function is to reduce the vibration transmitted from the road surface and control the energy flow, improving the ride comfort and energy utilization rate of the whole vehicle. Compared with the traditional shock absorber, it has a complete linear motor structure and can perform linear motion, replacing the hydraulic damping structure of the traditional shock absorber.

[0416] Among them, the lead-out structure is for the linear motor part in the electromagnetic actuator 1000. This linear motor is a motor in which the first component 220 and the second component 210 can perform relative linear displacement, and it includes the mover component and the stator component in the general sense of the motor.

[0417] In some embodiments, in combination Figure 27-Figure 35As shown, the electromagnetic actuator 1000 of this embodiment includes an upper support 500, an assembly nut 830, a center rod 300, a connecting wire 2121, a housing 100, a first component 220, a second component 210, a mounting bracket 192, etc. Among them, the upper support 500 is locked with the center rod 300 through the assembly nut 830. The connecting wire 2121 includes three phases A, B, and C. The connecting wire 2121, the center rod 300, and the second component 210 form the stator assembly of the electromagnetic actuator 1000. The first component 220 and the housing 100 form the rotor assembly of the electromagnetic actuator 1000. The mounting bracket 192 functions to connect the suspension system 10000.

[0418] In some embodiments, in combination with Fig.28 and Fig.29 As shown, the iron core assembly 211 has tooth grooves, and the winding assembly 212 is arranged in the tooth grooves. Each tooth groove surface is provided with a lead wire outlet groove 2015 for the lead wires of the winding assembly 212 in each tooth groove to pass out between the iron core assembly 211 and the housing 100, so that at least part of the structure of the first lead wire 2018 of the winding assembly 212 can be located between the iron core assembly 211 and the housing 100, realizing the external wiring of the winding assembly 212 and reducing the wiring difficulty of the winding assembly 212 and the arrangement difficulty of the connecting wire 2121.

[0419] In some embodiments, as Fig.28 shown, the outer surface of the iron core assembly 211 is provided with a groove 20111 for the cross-phase connection between the winding assemblies 212.

[0420] Specifically, as Fig.31 shown, the winding assembly 212 includes a first-phase winding 21214, a second-phase winding 21215, and a third-phase winding 21216. Between the first-phase winding 21214 and the first-phase winding 21214, between the second-phase winding 21215 and the second-phase winding 21215, and between the second-phase winding 21216 and the second-phase winding 21216, one end of the first lead wire 2018 needs to be connected to each other to form a series structure. In this embodiment, by providing a groove 20111 on the outer surface of the iron core assembly 211, it is beneficial for the first lead wires 2018 between phases to pass through. And welding or crimping and other processes are required between the first lead wires 2018. The groove 20111 can make the surrounding of the connection of the first lead wires 2018 unobstructed, with a large operating space and low implementation difficulty, which is beneficial for mass production.

[0421] In some embodiments, as Fig.30As shown, a wire slot 2013 is provided at the top of the iron core assembly 211. After the wiring between the three first lead-out heads 2018 is completed, the final connecting wire 2121 will reach the upper surface of the iron core assembly 211, and the three-phase wires will be directly buried in the wire slot 2013 on the upper surface, ensuring the smoothness of the wiring.

[0422] In some embodiments, a wire passing channel 330 is provided on the central rod 300, and the connecting wire 2121 passes through the wire passing channel 330 and extends to the outside of the housing 100.

[0423] In some embodiments, in combination Fig.28 with Fig.32 as shown, the wire passing channel 330 is formed on the outer wall of the central rod 300. In this way, the connecting wire 2121 does not need to pass through inside and outside, and fits perfectly with the outer wall of the central rod 300, reducing the connection difficulty of the connecting wire 2121.

[0424] In some embodiments, the connecting wire 2121 can be fixed by gluing, injection molding or covered with a protective shell to strengthen the fit between the connecting wire 2121 and the central rod 300, and the operation is convenient and there is sufficient operation space.

[0425] In some embodiments, in combination Fig.30 with Fig.32 as shown, the wire slot 2013 can be linear, spiral or curved, and the wire slot 2013 can be one or multiple, and multiple can converge into one or one can branch into multiple, all within the scope of this embodiment.

[0426] In addition, as Fig.33 shown, the arrangement order of the first-phase winding 21214, the second-phase winding 21215 and the third-phase winding 21216 can be changed arbitrarily, and there is wiring operation for all of them.

[0427] Meanwhile, in combination Fig. 27 , Fig.34 and Fig.35 as shown, the iron core assembly 211 and the central rod 300 can be integrated or split. A groove 20111 is provided on the outer surface of the iron core assembly 211, and the groove 20111 is used for the cross-phase connection between the winding assemblies 212.

[0428] In summary, in this embodiment, the connecting wire 2121 is buried in the outer wall of the iron core assembly 211, and will not interfere with the first component 220. Similarly, it also avoids the inner walls of the upper support 500 and the assembly nut 830, does not affect the assembly of the upper support 500 and the central rod 300, and will not cause interference problems, making the lead wire maintenance of the winding assembly 212 convenient, having sufficient operation space, being friendly to the arrangement of the connecting wire 2121, and at the same time leaving the internal space of the iron core assembly 211, facilitating the cooling design.

[0429] In some embodiments, in combination with Figure 36-Figure 40 As shown, the winding assembly 212 has a second lead-out end 214, and at least part of the structure of the second lead-out end 214 is located between the iron core assembly 211 and the center rod 300. To achieve lead-out from the inner side of the winding assembly 212, reduce the difficulty of lead-out of the winding assembly 212 and reduce the occupied space of the second component 210, and reduce the forming difficulty of the second component 210.

[0430] In some embodiments, the second lead-out end 214 is connected to the connecting wire 2121 to ensure the working performance of the winding assembly 212.

[0431] In some embodiments, such as Fig.40 As shown, the wire passing channel 330 includes a radial hole 333 and an axial hole 334, and the radial hole 333 is communicated with the axial hole 334. Here, it means that the wire passing channel 330 includes a radial hole 333 extending radially along the electromagnetic actuator 1000 and an axial hole 334 extending axially along the electromagnetic actuator 1000, and the radial hole 333 is communicated with the axial hole 334 so that the connecting wire 2121 can effectively pass through the wire passing channel 330 and extend out, reducing the difficulty of leading out the connecting wire 2121.

[0432] In some embodiments, the connecting wire 2121 passes through the axial hole 334 and the radial hole 333 and is connected to the second lead-out end 214 of the winding assembly 212 to realize the connection between the second lead-out end 214 and the connecting wire 2121.

[0433] In some embodiments, in combination with Figure 36-Figure 40 As shown, the electromagnetic actuator 1000 of this embodiment includes a center rod 300, an iron core assembly 211, a winding assembly 212, a first component 220 and a housing 100. Among them, the center rod 300, the iron core assembly 211 and the winding assembly 212 together form the stator assembly of the electromagnetic actuator 1000, and the first component 220 and the housing 100 together form the rotor assembly of the electromagnetic actuator 1000.

[0434] In some embodiments, the iron core assembly 211 is press-fitted or screwed onto the center rod 300, the winding assembly 212 is wound or placed on the iron core assembly 211, and the three-phase wires of the winding assembly 212 need to be led out from the iron core assembly 211 and led out from the top end of the center rod 300 for easy connection to the motor controller.

[0435] In some embodiments, in combination with Fig.38 and Fig.39As shown, a wire head outlet groove 2015 and a radial hole 333 are respectively formed in the iron core assembly 211. Among them, the outer wire head of the winding assembly 212 passes through the wire head outlet groove 2015 from the outermost edge of the iron core assembly 211 and returns to the inside to reach the radial hole 333, and is led out internally through the radial hole 333, while the inner wire head of the winding assembly 212 can be directly led out through the radial hole 333, so as to realize that at least part of the structure of the second lead-out head 214 is arranged between the iron core assembly 211 and the center rod 300.

[0436] It should be noted that each iron core assembly 211 and winding assembly 212 on the second component 210 are led out in this way, and the wiring between the wire heads can be carried out according to the design of the three-phase lines.

[0437] It should also be noted that compared with arranging at least part of the structure of the lead-out head of the winding assembly 212 between the iron core assembly 211 and the casing 100, this embodiment occupies less space and does not affect the winding space of the winding assembly 212. The slot fill factor is greatly improved compared with the external lead-out method, so that more electromagnetic thrust can be obtained under the same space, and to a certain extent, it is ensured that the performance of the electromagnetic actuator 1000 can be greatly improved.

[0438] In some embodiments, the wire head outlet groove 2015 can be a straight groove or an inclined groove. According to requirements, the number of wire head outlet grooves 2015 can be single or multiple. Usually, multiple wire head outlet grooves 2015 are evenly distributed to obtain better results, and the width of the wire head outlet groove 2015 depends on the wire diameter used in the electromagnetic actuator 1000. The notch shape of the wire head outlet groove 2015 can be a circular arc notch or a square notch, etc.

[0439] In some embodiments, a communicating guide rod end outlet groove 331 and a winding section outlet groove 332 are respectively formed in the axial direction of the center rod 300. Both the guide rod end outlet groove 331 and the winding section outlet groove 332 are arranged on the outer wall surface of the center rod 300. The second lead-out heads 214 of the winding assembly 212 all converge into the winding section outlet groove 332 for inter-phase wiring operations, and finally the lead-out of the winding section is completed. By forming the guide rod end outlet groove 331 on the center rod 300, the connecting wire 2121 led out from the winding assembly 212 can be directly buried into the center rod 300 without changing the overall direction of the lead-out, making the lead-out operation of the connecting wire 2121 convenient and fast, without changing the natural direction of the connecting wire 2121, and there is no need to penetrate into the internal space of the center rod 300 for lead-out, retaining the natural lead-out state of the three-phase lines, causing little damage to the connecting wire 2121 itself, effectively improving the durability of the connecting wire 2121, and the internal space of the center rod 300 can be vacated for cooling arrangement to improve the performance of the electromagnetic actuator 1000.

[0440] It should be noted that when the diameter of the connecting wire 2121 used in the winding assembly 212 is small, the winding segment outlet groove 332 may not be provided, and the wire may be led out directly along the outer wall of the central rod 300.

[0441] In some embodiments, as Fig.40 shown, when the central rod 300 and the iron core assembly 211 are an integral part, the iron core assembly 211 includes a plurality of placement grooves 2119 spaced along the axial direction of the central rod 300, and the winding assembly 212 is placed in the plurality of placement grooves 2119. To achieve the mating connection between the winding assembly 212 and the iron core assembly 211, so as to facilitate the formation of the second component 210.

[0442] In some embodiments, as Fig.40 shown, a wire routing space 2011 is provided in the middle of the iron core assembly 211, and each placement groove 2119 is provided with a radial hole 333 communicating with the wire routing space 2011. To achieve internal wire leading-out of the winding assembly 212.

[0443] In summary, this embodiment can effectively improve the slot fill factor of the electromagnetic actuator 1000, thereby improving the performance of the electromagnetic actuator 1000, and burying the connecting wire 2121 into the wall thickness of the central rod 300, without occupying extra space and without changing the natural routing of the connecting wire 2121 itself, which is beneficial to extending the service life of the connecting wire 2121 and is convenient and fast to operate.

[0444] In some embodiments, in combination with Figure 41-Figure 48 shown, the iron core assembly 211 includes a plurality of stator cores 2014, the stator cores 2014 are arranged along the axial direction of the central rod 300, and the stator core 2014 includes: a stator tooth portion 2141 and a stator yoke portion 2142, the stator tooth portion 2141 includes a plurality of first laminations 21411 stacked along the axial direction of the central rod 300, the stator yoke portion 2142 is formed in a ring shape and is provided on the stator tooth portion 2141, at least part of the stator yoke portion 2142 is located on one side of the stator tooth portion 2141 so as to form a winding slot 2133 between the stator tooth portion 2141 and the stator yoke portion 2142, the winding assembly 212 includes a multi-phase winding, and the coils 2123 of the winding (the specific structure of the coils 2123 can be referred to Fig.65 ) are all placed on the winding slot 2133. Thus, the winding assembly 212 is arranged on the iron core assembly 211 to ensure the working performance of the second component 210 and reduce the assembly difficulty of the second component 210.

[0445] It should be noted that by arranging the stator tooth portion 2141 to include a plurality of first laminations 21411 stacked axially along the central rod 300, compared with the structure in which the stator tooth portion 2141 is arranged as a single piece of conductor, the eddy current loss of the stator tooth portion 2141 can be effectively reduced, thereby improving the thrust and efficiency of the electromagnetic actuator 1000.

[0446] In some embodiments, the winding groove 2133 is formed on one axial side of the stator tooth portion 2141 and located on the radially outer periphery of the stator yoke portion 2142, so as to facilitate placing the coil 2123 of the winding on the winding groove 2133.

[0447] In some embodiments, in combination with Figure 41-Figure 48 As shown, the stator yoke portion 2142 is arranged on one axial side of the stator tooth portion 2141. So that a winding groove 2133 is formed between the stator tooth portion 2141 and the stator yoke portion 2142, thereby facilitating placing the coil 2123 of the winding on the winding groove 2133, reducing the matching difficulty between the winding assembly 212 and the iron core assembly 211, and ensuring the working performance of the second component 210.

[0448] In some embodiments, in combination with Figure 41-46 As shown, the stator yoke portion 2142 includes a plurality of second laminations 21422 stacked on top of each other, and the plurality of second laminations 21422 are stacked radially along the central rod 300. To effectively reduce the eddy current loss of the stator tooth portion 2141.

[0449] That is to say, the plurality of first laminations 21411 of the stator tooth portion 2141 are stacked axially along the central rod 300, and the plurality of second laminations 21422 of the stator yoke portion 2142 are stacked radially along the central rod 300. The axially laminated tooth portion and the radially laminated yoke portion can significantly reduce the eddy current loss in the stator tooth portion 2141.

[0450] In some embodiments, as shown in Fig.41 and Fig.42 As shown, the stator tooth portion 2141 and the stator yoke portion 2142 are made by stamping and laminating an integral silicon steel sheet. The integral stamping structure can also ensure the thrust and efficiency of the electromagnetic actuator 1000, while reducing the thrust fluctuation of the electromagnetic actuator 1000.

[0451] At the same time, the integral stamping structure also has the advantages of fewer structural cross-sections, less gluing, high assembly accuracy, and no impact on the thrust efficiency of the electromagnetic actuator 1000.

[0452] Of course, in some other embodiments, in combination with Fig.44 and Fig.45As shown, the stator yoke 2142 can also be fixed to the stator teeth 2141 to form the stator core 2014. That is to say, the stator core 2014 can also be made by fixing the independent stator yoke 2142 and stator teeth 2141.

[0453] In some embodiments, the stator yoke 2142 is connected to the stator teeth 2141 to make the relative positions of the stator yoke 2142 and the stator teeth 2141 stable, ensuring the working performance of the stator core 2014.

[0454] In some embodiments, the stator yoke 2142 and the stator teeth 2141 are connected by laser welding to strengthen the connection.

[0455] It should be noted that the above assembly method of the stator yoke 2142 and the stator teeth 2141 can make the stator core 2014 have the advantages of separate lamination and mature process. The stator core 2014 can be applied to the complex iron core assembly 211 structure.

[0456] In some other embodiments, Fig.45 and Fig.46 As shown, the stator yoke 2142 is axially inserted and fixed into the axially laminated stator teeth 2141. In this way, the stator core 2014 can also be made by fixing the independent stator yoke 2142 and stator teeth 2141.

[0457] In some embodiments, the stator yoke 2142 is inserted into the stator teeth 2141 and is connected to the stator teeth 2141 by laser welding to strengthen the connection. When ensuring a certain assembly accuracy, it also ensures the tight connection between the stator yoke 2142 and the stator teeth 2141.

[0458] In addition, the above matching form can greatly reduce the eddy current loss of the iron core assembly 211, improve the installation accuracy, reduce the influence on the thrust and efficiency of the linear motor, and weaken the thrust fluctuation.

[0459] In some embodiments, Fig.47 and Fig.48 As shown, the stator yoke 2142 includes a plurality of second laminations 21422 stacked. The plurality of second laminations 21422 are stacked along the axial direction of the central rod 300. That is to say, it is not limited to stacking the plurality of second laminations 21422 along the radial direction of the central rod 300. The plurality of second laminations 21422 can also be arranged to be stacked along the axial direction of the central rod 300. Since the axial stamping and lamination process of silicon steel sheets is very mature, the process feasibility of this technical solution is high.

[0460] In summary, the stator core 2014 is made by fixing axially laminated silicon steel sheets on axially laminated silicon steel sheets.

[0461] In some embodiments, the stator yoke 2142 and the stator teeth 2141 are connected by laser welding.

[0462] Through the above-mentioned matching method, the stator yoke 2142 and the stator teeth 2141 can be separately laminated, with high axial installation accuracy, without affecting the thrust and efficiency of the linear motor, and reducing the thrust fluctuation.

[0463] In some embodiments, in combination with Figure 41-46 As shown, the stator yoke 2142 is a wound part, and the wound part is wound circumferentially around the central rod 300. It should be noted that the wound part here means that the stator yoke 2142 is formed by helically winding a whole silicon steel sheet around the axis, and its function is equivalent to that of axially laminating silicon steel sheets to weaken the eddy current loss of the stator teeth 2141, that is, it can weaken the eddy current loss in the stator yoke 2142 to a greater extent.

[0464] In some embodiments, in combination with Figure 41-46 As shown, a first central hole 21412 is formed in the stator teeth 2141, and the stator yoke 2142 is located in the first central hole 21412. To achieve setting the stator yoke 2142 on the stator teeth 2141 and reducing the matching difficulty between the stator teeth 2141 and the stator yoke 2142.

[0465] In some embodiments, in combination with Figure 41-46 As shown, a second central hole 21421 is formed in the stator yoke 2142, and both the first central hole 21412 and the second central hole 21421 are formed as mounting holes for the stator core 2014 and the central rod 300. Thus, it is convenient to assemble the stator core 2014 on the central rod 300 and achieve the mating connection between the stator core 2014 and the central rod 300.

[0466] In some embodiments, in combination with Figure 41-Figure 48 As shown, a positioning protrusion 21415 that mates with the central rod 300 is formed on at least one of the stator yoke 2142 and the stator teeth 2141. In this way, during the assembly process, the stator yoke 2142 and the stator teeth 2141 can form an interference fit with the central rod 300, ensuring the connection strength and relative position stability between the iron core assembly 211 and the central rod 300, avoiding the situation that the iron core assembly 211 rotates circumferentially on the structure of the central rod 300 during movement, improving the assembly accuracy between the stator yoke 2142 and the central rod 300, and while significantly weakening the eddy current loss, reducing the impact on the thrust and efficiency of the linear motor.

[0467] In some embodiments, in combination with Figure 41-Figure 48As shown, the stator yoke 2142 and the stator tooth 2141 are both formed with positioning protrusions 21415 that cooperate with the center rod 300 , so that the stator yoke 2142 and the stator tooth 2141 can form a tight fit with the center rod 300 .

[0468] In some embodiments, in combination Figure 41-Figure 48 As shown, a groove 20111 is formed on the stator tooth portion 2141 for cross-phase connection between the coils 2123 .

[0469] At the same time, by forming positioning protrusions 21415 that cooperate with the center rod 300 on the stator yoke 2142 and the stator tooth 2141, the alignment of the grooves 20111 can be ensured, thereby reducing the difficulty of wiring the coil 2123.

[0470] In some embodiments, in combination Figure 49-Figure 53 As shown, the stator yoke 2142 is formed as an integral piece. That is, the stator yoke 2142 is not limited to being formed as a winding piece, but can also be formed as an integral piece to reduce the difficulty of forming the stator yoke 2142.

[0471] In some embodiments, in combination Figure 49-Figure 53 As shown, the stator yoke 2142 includes a body 21427 and a plug-in portion 21428, and the plug-in portion 21428 is formed on one side of the body 21427 along the axial direction of the center rod 300. In order to realize the fixed connection between the stator yoke 2142 and the stator tooth portion 2141 by using the plug-in portion 21428, and reduce the difficulty of connecting the stator yoke 2142 and the stator tooth portion 2141.

[0472] In some embodiments, in combination Figure 49-Figure 53 As shown, the stator tooth portion 2141 is made of axially laminated silicon steel sheets, and the stator yoke portion 2142 is made of machined solid material, wherein the material of the stator yoke portion 2142 is soft magnetic material, and positioning protrusions 21415 that cooperate with the center rod 300 are formed on the stator yoke portion 2142 and the stator tooth portion 2141, and a groove 20111 is formed on the stator tooth portion 2141 for cross-phase connection between the coils 2123.

[0473] In some embodiments, in combination Fig.49 , Fig.50 and Fig.51 As shown, the plug-in portion 21428 is formed as a boss on the main body 21427, and a first connecting structure 21416 is formed on the stator tooth portion 2141. The first connecting structure 21416 can be formed into a dovetail groove, and the boss is inserted into the dovetail groove and fixed to the stator tooth portion 2141. At the same time, laser welding is used to further strengthen the connection strength between the stator yoke portion 2142 and the stator tooth portion 2141, thereby achieving a fixed connection between the stator yoke portion 2142 and the stator tooth portion 2141.

[0474] Meanwhile, the above structure can also significantly reduce the eddy current loss in the iron core assembly 211 of the stator teeth 2141, while ensuring the thrust and efficiency of the linear motor.

[0475] In some embodiments, the first connection structure 21416 formed as a dovetail groove is punched out by the same trapezoidal punch, such that the opening of the first connection structure 21416 is wider closer to the outer edge of the stator teeth 2141. In this way, when the insertion portion 21428 is inserted into the first connection structure 21416, since the width of the dovetail groove opening is smaller than the width of the dovetail groove bottom, it can be ensured that the insertion portion 21428 cannot slip out within the first connection structure 21416, strengthening the fixing strength between the stator yoke 2142 and the stator teeth 2141.

[0476] In some embodiments, the opposite ends of the bottom of the dovetail groove are rounded away from the inside of the dovetail groove. The rounding is formed by a punch with a rounded corner. Using a punch with a rounded corner can improve the service life of the punch. At the same time, by providing a rounded corner on the dovetail groove, it is also possible to avoid interference between the insertion portion 21428 and the first connection structure 21416 during the assembly process, ensuring that the insertion portion 21428 can be normally inserted into the first connection structure 21416 along the axial direction and completing the fixation between the stator yoke 2142 and the stator teeth 2141.

[0477] In addition, when the insertion portion 21428 is inserted into the first connection structure 21416, since a rounded corner is formed between the side surface of the insertion portion 21428 and the bottom end surface of the body 21427, the bottom end surface of the body 21427 cannot fit with the end surface of the stator teeth 2141. Therefore, in this embodiment, an inclined surface is formed between the bottom end surface of the body 21427 and the side surface of the insertion portion 21428, which is inclined towards the center line of the insertion portion 2142. When there is a rounded corner between the side surface of the insertion portion 21428 and the bottom end surface of the body 21427, it can ensure the fitting between the stator yoke 2142 and the stator teeth 2141, thus ensuring the reliability of the structure.

[0478] In some embodiments, in combination Fig.52 and Fig.53 as shown, the stator yoke 2142 includes a body 21427 and an insertion portion 21428. The body 21427 is disposed on the axial side of a plurality of first laminations 21411, and the planar dimension of the body 21427 is the same as the inner and outer diameters of the first laminations 21411. The insertion portion 21428 is inserted and fitted in the first central hole 21412, and in this way, the fixed connection between the stator yoke 2142 and the stator teeth 2141 can also be realized.

[0479] Optionally, in combination Fig.52 and Fig.53As shown, a second anti-rotation protrusion 21417 is provided on the stator tooth portion 2141, and an anti-rotation groove 21425 is provided on the stator yoke portion 2142. The second anti-rotation protrusion 21417 is fitted into the anti-rotation groove 21425 to achieve the fixed fit between the stator tooth portion 2141 and the stator yoke portion 2142, prevent the stator tooth portion 2141 from rotating, further ensure the alignment of the groove 20111, and reduce the wire outlet difficulty of the coil 2123.

[0480] In some embodiments, after the stator yoke portion 2142 and the stator tooth portion 2141 are connected by fitting the second anti-rotation protrusion 21417 and the anti-rotation groove 21425, laser welding is further used to enhance the connection strength between the stator yoke portion 2142 and the stator tooth portion 2141.

[0481] In some embodiments, in combination with Fig.52 and Fig.53 As shown, a first boss structure 21426 is provided at the connection between the main body 21427 and the insertion portion 21428, which prevents the connection between the main body 21427 and the insertion portion 21428 from breaking and can further enhance the mechanical strength of the connection.

[0482] In some embodiments, in combination with Figure 54-Figure 58 As shown, a first connection structure 21416 and a second connection structure 21423 are respectively formed on the stator yoke portion 2142 and the stator tooth portion 2141, and the first connection structure 21416 is matched with the second connection structure 21423 to achieve the fitting connection between the stator yoke portion 2142 and the stator tooth portion 2141.

[0483] In some embodiments, in combination with Figure 54-Figure 58 As shown, the first connection structure 21416 is in plug-in fit with the second connection structure 21423, thereby achieving the plug-in fit between the stator yoke portion 2142 and the stator tooth portion 2141, reducing the fixing difficulty between the stator yoke portion 2142 and the stator tooth portion 2141, and ensuring the fixing quality, so that the relative position between the stator yoke portion 2142 and the stator tooth portion 2141 is stable.

[0484] In some embodiments, in combination with Figure 54-Figure 58 As shown, a plurality of second connection structures 21423 are provided below the stator yoke portion 2142. The second connection structures 21423 are formed into column structures, and the thickness of the columns is equal to the thickness of the stator tooth portion 2141. A plurality of first connection structures 21416 that cooperate with the column structures are provided on the stator tooth portion 2141. The first connection structures 21416 are formed into dovetail grooves, and the column structures are inserted into the dovetail grooves at corresponding positions of the stator tooth portion 2141 to fixedly connect the stator yoke portion 2142 and the stator tooth portion 2141.

[0485] It should be noted that since the coil 2123 surrounds the stator yoke 2142 and is wound around the stator teeth 2141, when the electromagnetic actuator 1000 operates, the magnetic lines of force mainly move along the radial direction within the stator teeth 2141 and the axial direction within the stator yoke 2142. Among them, the stator teeth 2141 can significantly reduce the eddy current loss generated within the teeth through axially laminated silicon steel sheets, and the stator yoke 2142 reduces the eddy current loss in the stator yoke 2142 through circumferentially wound silicon steel sheets.

[0486] In some embodiments, the stator yoke 2142 is formed by a process of stamping and then winding. Among them, the same punch is used during stamping, and the shape of the punch is trapezoidal. Because if a square punch is used, there will be an assembly interference at the connection between the column structure and the stator yoke 2142 and in a local area of the stator teeth 2141. At the same time, if no fillet is designed, the life of the punch will be greatly shortened, resulting in an increase in cost.

[0487] Therefore, in this embodiment, the same trapezoidal punch with a fillet is used to process the second connection structure 21423, which can reduce the process cost and meet the process assembly requirements.

[0488] In addition, when the second connection structure 21423 cooperates with the first connection structure 21416, when the second connection structure 21423 is inserted into the dovetail groove opened in the stator teeth 214, since there is a fillet formed between the side surface of the second connection structure 21423 and the bottom end surface of the stator yoke 2142, there is a risk that the bottom end surface of the stator yoke 2142 and the end surface of the stator teeth 2141 cannot be fitted. By using a trapezoidal punch, an inclined surface 21424 (as shown in Fig.58 ) that is inclined towards the center line of the second connection structure 21423 can be formed between the bottom end surface of the stator yoke 2142 and the side surface of the second connection structure 21423. This can ensure that the stator yoke 2142 and the stator teeth 2141 can be fitted when there is a fillet between the bottom end surface of the second connection structure 21423 and the stator yoke 2142, thereby ensuring the reliability of the structure.

[0489] It should also be noted that since the same punch is used during the stamping of the second connection structure 21423, the width of the rolled second connection structure 21423 will vary radially. Among them, the closer to the outer edge of the stator yoke 2142 in the radial direction, the wider the width of the second connection structure 21423, so that the stator yoke 2142 is formed into a dovetail trapezoidal shape.

[0490] In some embodiments, such as Fig.57As shown, multiple first connection structures 21416 formed as dovetail grooves are punched at fixed positions on the stator tooth portion 2141. When the second connection structure 21423 is inserted into the first connection structure 21416, since the notch width of the dovetail groove is smaller than the bottom width of the dovetail groove, it can be ensured that the second connection structure 21423 cannot slip out within the first connection structure 21416, strengthening the fixing strength between the stator yoke portion 2142 and the stator tooth portion 2141.

[0491] In some embodiments, such as Fig.57 As shown, rounded corners are provided at the inner corners of the slots of the first connection structure 21416. If the second connection structure 21423 is provided with a structure that cooperates with the rounded corners, it can avoid interference between the stator yoke portion 2142 and the stator tooth portion 2141 during installation, thereby ensuring that the second connection structure 21423 on the stator yoke portion 2142 can be normally inserted into the first connection structure 21416 of the stator tooth portion 2141 and completing the fixed connection between the stator yoke portion 2142 and the stator tooth portion 2141.

[0492] In summary, with the combination of the column structure of the second connection structure 21423 and the dovetail groove structure of the first connection structure 21416 for the stator yoke portion 2142 and the stator tooth portion 2141 in this embodiment, the helically wound stator yoke portion 2142 and the axially laminated stator tooth portion 2141 can form a mechanical connection. At the same time, laser welding is used to further strengthen the connection strength between the stator yoke portion 2142 and the stator tooth portion 2141.

[0493] In some embodiments, in combination with Figure 59-Figure 66 As shown, the iron core assembly 211 includes a first type of iron core 2111 and a second type of iron core 2112. In the axial direction of the center rod 300, there are multiple second type of iron cores 2112, and both ends of the multiple second type of iron cores 2112 are provided with the first type of iron core 2111. The end face of the first type of iron core 2111 facing the second type of iron core 2112 is provided with a coil 2123, and both side end faces of the second type of iron core 2112 are provided with coils 2123. The phases of the coils 2123 located on both sides of the second type of iron core 2112 are the same. Thus, the cooperation connection between the iron core assembly 211 and the winding assembly 212 is realized, and the connection difficulty between the coils 2123 of each phase is reduced.

[0494] In some embodiments, the coils 2123 at both ends of each second type of iron core 2112 are connected in series, and the coils 2123 of the same phase axially spaced on the center rod 300 are welded and connected through a connecting wire 2121. Thus, the welded connection of the coils 2123 of the same phase is realized, ensuring the performance of the winding assembly 212.

[0495] In some embodiments, in combination with Figure 59-Figure 66As shown, in this embodiment, the iron core assembly 211 is ingeniously designed to be composed of a first type of iron core 2111 and a second type of iron core 2112. The coils 2123 on the same second type of iron core 2112 are in-phase coils, and the coils 2123 on the same second type of iron core 2112 are wired by welding. In this way, it comprehensively surpasses the traditional design in many aspects such as layout space, production efficiency, processing difficulty, maintenance convenience, structural complexity, and part consistency.

[0496] Among them, in combination with Fig.60 、 Fig.61 and Fig.62 As shown, the second component 210 of this embodiment mainly consists of a connecting wire 2121, an iron core assembly 211, an insulating skeleton 213, coils 2123, insulating paper 2122, etc. The connecting wires 2121 are respectively for three phases A, B, and C. The coils use flat wires to increase the space utilization rate. The connecting wires 2121 are bent and led out at the cut-off points of the coils 2123 through the grooves 20111 opened on the surface of the iron core assembly 211 and the wire grooves 2132 opened on the surface of the insulating skeleton 213. The first type of iron core 2111 has coils 2123 arranged on one side.

[0497] Optionally, the middle part of the second component 210 in the axial direction is assembled by the second type of iron core 2112, the insulating skeleton 213, and the coils 2123, and the end part of the second component 210 is assembled by the first type of iron core 2111, the coils 2123, and the insulating skeleton 213. Among them, the coils 2123 on the first type of iron core 2111 are coils 2123 of phase A.

[0498] In a specific example, the composition order on the second component 210 from the starting end is the coil 2123 of phase A, the coil 2123 of phase B, and the coil 2123 of phase C in sequence. The adjacent two out-of-phase coils 2123 are separated by insulating paper 2122, and the in-phase coils 2123 are connected in series. Inside the second component 210, the bilateral coils are also connected in series. When wiring the coils 2123, the lead wires of the coils 2123 are welded to the connecting wires 2121 bent at the cut-off points of the coils 2123 to achieve the connection of the circuit and reduce wiring errors.

[0499] In some embodiments, in combination with Fig.63 、 Fig.64 and Fig.65As shown, the first type of iron core 2111 is provided with a first annular groove 21111, a wire slot 2013, and a groove 20111. The structure of the insulating skeleton 213 is similar to that of the first type of iron core 2111. The insulating skeleton 213 is provided with a second annular groove 2138, a lead channel 2131, and a wire passing groove 2132. The insulating skeleton 213 is nested in the first annular groove 21111. The coil 2123 is formed with a lead wire 21231 and a first lead-out head 2018. When the coil 2123 is processed, the lead wire 21231 is bent at a right angle, and the winding is carried out from the inside to the outside. At the cut-off point of the coil 2123, two bends are made to form the first lead-out head 2018. During assembly, the coil 2123 is nested in the first annular groove 21111, and the lead wire 21231 extends to the outside of the first type of iron core 2111 through the wire slot 2013 and the lead channel 2131 for wiring and connecting to the power supply. This method has a simple structure, good consistency in processing methods, simple processing technology, few operation steps, and a large operation space, which is conducive to reducing costs and improving production efficiency.

[0500] In some embodiments, as Fig.66 shown, the second type of iron core 2112 is also provided with an insulating skeleton 213 and a coil 2123. Both sides of the second type of iron core 2112 have a first annular groove 21111, a wire slot 2013, and a groove 20111. The insulating skeleton 213 is nested in the first annular groove 21111, and the in-phase coil 2123 is nested on the insulating skeleton 213. The two wire slots 2013 are 180° apart. The first lead-out head 2018 of the coil 2123 on one side is connected in series with the first lead-out head 2018 of the coil 2123 on the other side at the welding point, making the component structures the same, the structure simple, and the production and processing efficiency high, which is conducive to batch production and cost control.

[0501] At the same time, by arranging the coils 2123 on both end faces of the second type of iron core 2112, the space utilization rate is high.

[0502] In some embodiments, according to the different opening directions of the lead channels 2131 of the insulating skeleton 213, the bending methods of the leads of the coil 2123 are divided into two types. For example, the lead wire 21231 is bent and led out from above the coil 2123; or, the lead wire 21231 is bent and led out from below the coil 2123. The winding methods of the coil 2123 are the same, both from the inside to the outside, and the winding method is simple.

[0503] In some embodiments, the connection between the in-phase coils 2123 is also in series, and the connection points still adopt the welding method, which has good operability, simple process, is conducive to production and processing, and the solder joints are on the outside, which is more intuitive during assembly and welding, is conducive to avoiding wiring errors, improving production efficiency, and this method has a large operation space, is convenient to operate, and saves working hours.

[0504] In summary, the iron core assembly 211 of this embodiment is stacked by independent modules. The module units are separated by insulating paper 2122. The basic components of each module are an iron core, an insulating skeleton 213, and a coil 2123. The processing technology of each part is simple, the structures are basically the same, the structural complexity is low, the assembly is convenient, which is conducive to mass production and processing, saving costs and man-hours, and improving production efficiency.

[0505] In some embodiments, in combination with Figure 67-Figure 71 as shown, the iron core assembly 211 of this embodiment is mainly applied to the linear motor assembly of the electromagnetic suspension. The iron core assembly 211 belongs to the stator assembly. On the one hand, it provides support for the coil 2123, the insulating skeleton 213, etc. On the other hand, it provides a path for the magnetic field generated by the winding assembly 212 and bears the interaction force generated between the magnetic field and the dynamic permanent magnet. Multiple iron core assemblies 211 and winding assemblies 212 are stacked and fixed axially to form the second assembly 210.

[0506] In some embodiments, in combination with Fig.67 and Fig.68 as shown, the iron core assembly 211 includes a third type of iron core 2110. The third type of iron core 2110 includes a support frame 2016 and a support iron core 2017. Multiple support iron cores 2017 are assembled and stacked in the circumferential direction to form an annular iron core. The annular iron core and the support frame 2016 form a laminated third type of iron core 2110.

[0507] In some embodiments, in combination with Fig.68 , Fig.69 and Fig.70 as shown, a convex structure is provided at the inner end of the support iron core 2017, and a support groove is provided on the outer cylindrical surface of the support frame 2016. The support groove and the convex structure of the support iron core 2017 cooperate with each other to limit and support the root of the support iron core 2017, ensuring the structural stability of the third type of iron core 2110.

[0508] It should be noted that, as Fig.71 shown, since the coil 2123 and the support iron core 2017 are axially stacked, the support frame 2016 is also used to bear the weights of the support iron core 2017 and the coil 2123, etc. By providing a support groove on the outer cylindrical surface of the support frame 2016, it is also possible to prevent this weight from being directly borne by the third type of iron core 2110, improving the reliability of the third type of iron core 2110.

[0509] In some embodiments, the support frame 2016 can be designed as an integral structure or as an upper and lower split structure and then connected by fasteners or other means.

[0510] In a specific example, the support frame 2016 adopts an integral design solution to reduce the forming difficulty of the support frame 2016 and improve the structural strength of the support frame 2016.

[0511] In some embodiments, as Fig.67 shown, grooves 20111 can be provided at the outer ends of the support iron cores 2017 as required for connection between different coils 2123.

[0512] Among them, the positions, shapes and quantities of the grooves 20111 can be adjusted as required. It is recommended that the shapes of the grooves 20111 of the same third - type iron core 2110 be unified, which can reduce the specifications of the support iron core 2017.

[0513] In some embodiments, as Fig.69 shown, the support iron core 2017 is fan - shaped, with the inner side thin and the outer side thick. At the same time, on the premise that the support iron core 2017 meets process, use and other requirements, the thickness of the support iron core 2017 should be as thin as possible, and the shape of a single support iron core 2017 can be adjusted as required, such as setting grooves 20111, but it is necessary to meet the mating relationship between the circumferential support iron cores 2017 and meet the requirements of the shape of the third - type iron core 2110, and the specifications of the support iron core 2017 should be reduced as much as possible to facilitate production and assembly.

[0514] In some embodiments, the support iron core 2017 is made of a magnetic - conductive material, and a material with a high resistivity is preferably selected. Insulating materials, such as coating insulating paint, are provided on the left and right two side surfaces along the circumferential lamination direction. In addition, an adhesive substance also needs to be coated. Different support iron cores 2017 are reliably connected together through the adhesive substance. While meeting the requirements, the thickness of the coating should be as thin as possible to reduce the space occupation and avoid excessive reduction of the magnetic permeability of the third - type iron core 2110.

[0515] In some embodiments, if the adhesive substance meets the insulation requirements, the insulating material may not need to be coated again.

[0516] In some embodiments, as Fig.70 shown, the support frame 2016 is annular and made of a magnetic - conductive material, and a material with a high resistivity is preferably selected. On the premise of meeting process, use requirements, etc., the thickness of the support frame 2016 should be as thin as possible.

[0517] In some embodiments, as Fig.70 shown, a second positioning portion 350 is provided on the inner cylindrical surface of the support frame 2016, and a first positioning portion 340 is provided on the center rod 300 (for the specific structure of the first positioning portion 340, reference can be made to Fig.25) The first positioning portion 340 and the second positioning portion 350 cooperate to keep the central rod 300 and the support frame 2016 relatively stationary, thereby achieving circumferential limitation of the third type of iron core 2110 and the central rod 300, avoiding rotation of the third type of iron core 2110 around the central rod 300, and ensuring the working performance of the third type of iron core 2110.

[0518] In some embodiments, the first positioning portion 340 is formed as a groove provided on the outer peripheral wall of the central rod 300, the second positioning portion 350 is a positioning groove, and the anti-rotation rod 360 is provided between the first positioning portion 340 and the second positioning portion 350 to limit the positions of the central rod 300 and the support frame 2016, so that the central rod 300 and the support frame 2016 are relatively stationary and reduce the difficulty of limiting the positions of the central rod 300 and the support frame 2016.

[0519] Optionally, the shape and quantity of the second positioning portion 350 can be set according to requirements.

[0520] In some embodiments, as Fig.71 shown, the third type of iron core 2110 is stacked and installed along the axial direction of the stator central rod, coils 2123 are placed between the third type of iron cores 2110. After the electromagnetic actuator 1000 is powered on, the coils 2123 will be energized to generate a magnetic field. If the current changes, the magnetic field will also change accordingly. This change will cause an induced current, that is, eddy current, to be generated inside the third type of iron core 2110. The eddy current will generate heat loss and reduce the working efficiency of the electromagnetic actuator 1000. By arranging the third type of iron core 2110 to be divided into several support iron cores 2017 in the circumferential direction and insulating design between the support iron cores 2017, the original longer eddy current loop can be interrupted, allowing it to only pass through a smaller cross-section in the narrow loop of each support iron core 2017, increasing the resistance on the eddy current path, reducing the eddy current, thereby reducing the eddy current loss, and selecting a material with a high resistivity also increases the resistance on the eddy current path.

[0521] In some embodiments, since the circumferential direction of the support frame 2 is a continuous structure, eddy current loss will be generated. Therefore, the thickness of the support frame 2 should be as thin as possible.

[0522] In some embodiments, as shown in Figure 72 to Figure 118 shown, the electromagnetic actuator 1000 further includes a wiring assembly 2113. The coils 2123 of the same phase arranged at axial intervals on the central rod 300 are electrically connected through the wiring assembly 2113, thereby achieving electrical connection of the coils 2123 of the same phase and reducing the difficulty of electrical connection of the coils 2123 of the same phase.

[0523] In some embodiments, as shown in Figure 77-Figure 86As shown, the wiring assembly 2113 includes a conductive member 2114 and an insulating layer 2115. The insulating layer 2115 wraps the conductive member 2114, and limiting members 2116 for positioning and electrically connecting the coil 2123 are provided at both ends of the conductive member 2114. That is to say, the limiting members 2116 are used to position the coil 2123 and electrically connect with the coil 2123, so as to realize the electrical connection of the in-phase coils 2123 and ensure the position stability of the coil 2123.

[0524] At the same time, by arranging the insulating layer 2115 to wrap the conductive member 2114, while extending the service life of the conductive member 2114, the use safety of the conductive member 2114 can also be improved.

[0525] In some embodiments, in combination with Figure 78-Figure 86 As shown, the limiting member 2116 forms a wire clamping groove provided on the conductive member 2114. Thus, it is convenient to use the limiting member 2116 to position the coil 2123 and electrically connect with the coil 2123, realize the electrical connection of the in-phase coils 2123, and reduce the difficulty of electrical connection of the in-phase coils 2123.

[0526] It should be noted that the main innovation point of this embodiment is a winding wiring method applied to the electromagnetic actuator 1000, and this winding wiring method is novel, simple, efficient and reliable.

[0527] Among them, in combination with Figure 72-Figure 77 As shown, the electromagnetic actuator 1000 of this embodiment includes a mover assembly and a stator assembly. The mover assembly and the stator assembly can move relatively linearly. The stator assembly includes a central rod 300, a guide bearing 840, a sealing cover 312, a first iron core unit 21114, a plurality of second-type iron cores 2112, a second iron core unit 21115, a wiring assembly 2113, an outgoing line assembly 216, a connecting line 2121 and other components. The first iron core unit 21114, the plurality of second-type iron cores 2112 and the second iron core unit 21115 are all sleeved outside the central rod 300. The guide bearing 840 is assembled inside the central rod 300, and the sealing cover 312 is assembled on the top of the central rod 300, playing a role of limiting and sealing respectively.

[0528] In some embodiments, as Fig.77 As shown, the connecting line 2121 includes a first-phase lead 21211, a second-phase lead 21212 and a third-phase lead 21213. There are three outgoing ports 311 on the upper part of the central rod 300. The first-phase lead 21211, the second-phase lead 21212 and the third-phase lead 21213 respectively pass through the three outgoing ports 311 to facilitate the connection of the connecting line 2121 with the coil 2123.

[0529] In some embodiments, as Figure 87-Figure 92As shown, the first iron core unit 21114 includes a first type of iron core 2111, a coil 2123, and an inner wire outlet device 860. Among them, the coil 2123 is sleeved on the first type of iron core 2111. The coil 2123 is a multi-layered ring formed by winding a wire. The radially outer joint is bent outward along the circumferential winding direction to form a first wire outlet head 2018, and the radially inner joint is bent inward along the circumferential winding direction to form a second wire outlet head 214. The inner wire outlet device 860 is embedded inside the first type of iron core 2111 and connected to the second wire outlet head 214 of the coil 2123, facilitating the realization of in-phase electrical connection.

[0530] In some embodiments, as Fig.89 shown, the first type of iron core 2111 is provided with a first internal installation hole 21116 for assembling the inner wire outlet device 860 to realize embedding the inner wire outlet device 860 inside the first type of iron core 2111.

[0531] In some embodiments, the outer layer of the coil 2123 is provided with an insulating paint coating to protect the coil 2123.

[0532] It should be noted that since the bending directions of the first wire outlet head 2018 and the second wire outlet head 214 are the same as the winding direction of the coil 2123, and the bending is very smooth and does not cause any damage to other features of the coil 2123. Therefore, the paint coatings of the first wire outlet head 2018 and the second wire outlet head 214 can be peeled off to facilitate the connection between the inner wire outlet device 860 and the second wire outlet head 214.

[0533] In some embodiments, as Fig.89 and Fig.90 shown, the inner wire outlet device 860 includes a first insulating member 862 and a first wire 863. There is a first fitting 861 between the bottom of the first insulating member 862 and the first wire 863. In the first iron core unit 21114, the second wire outlet head 214 of the coil 2123 is clamped and connected to the first wire 863 through the first fitting 861 of the inner wire outlet device 860. The top of the first wire 863 is connected to the third-phase lead 21213 to realize the connection between the coil 2123 and the third-phase lead 21213, reducing the connection difficulty between the coil 2123 and the third-phase lead 21213.

[0534] In some embodiments, as Fig.89 shown, the outer side of the first type of iron core 2111 is provided with a plurality of grooves 20111, and the first wire outlet head 2018 of the coil 2123 is located in one of the grooves 20111 to reduce the connection difficulty of the first wire outlet head 2018.

[0535] In some embodiments, as Fig.93 、 Fig.94 and Fig.95As shown, the second type of iron core 2112 includes the second type of iron core 2112, two coils 2123, and an inner wiring device 870. The two coils 2123 are respectively sleeved on both sides of the second type of iron core 2112, and the inner wiring device 870 is embedded inside the second type of iron core 2112 to achieve the electrical connection between the inner wiring device 870 and the coil 2123.

[0536] In some embodiments, as Fig.95 shown, a second internal mounting hole 21122 for assembling the inner wiring device 870 is provided in the second type of iron core 2112 to embed the inner wiring device 870 inside the second type of iron core 2112.

[0537] In some embodiments, as Fig.96 and Fig.97 shown, the inner wiring device 870 includes a second insulating member 872 and a second wire 873. Two second fitting members 871 are formed between the bottom of the second insulating member 872 and the second wire 873. In the second type of iron core 2112, the second lead-out ends 214 of the upper and lower two coils 2123 are respectively clamped in the two second fitting members 871 of the inner wiring device 870 and connected to the second wire 873, so that the two coils 2123 on the same second type of iron core 2112 can form an electrical connection through the inner wiring device 870, thereby forming a conductive path.

[0538] In some embodiments, as Fig.95 shown, a plurality of grooves 20111 are provided on the outer side of the second type of iron core 2112, and the first lead-out ends 2018 of the two coils 2123 are both located in one of the grooves 20111 to reduce the connection difficulty of the first lead-out ends 2018.

[0539] In some embodiments, as Fig.98 , Fig.99 and Fig.100 shown, the second iron core unit 21115 includes a first type of iron core 2111, a coil 2123, and a bottom wiring device 880. Among them, the coil 2123 is sleeved above the first type of iron core 2111, the bottom wiring device 880 is located below the first type of iron core 2111, a third internal mounting hole 21117 is provided inside the first type of iron core 2111, and three grooves 20111 are also provided on the outer side of the first type of iron core 2111.

[0540] In some embodiments, as Fig.101 and Fig.102As shown, the bottom wiring device 880 includes a third insulating member 881 and a third wire 882. The third wire 882 is provided with a first-phase connector 8821, a second-phase connector 8822, and a third-phase connector 8823. In the second iron core unit 21115, the third-phase connector 8823 is embedded in a third internal mounting hole 21117 inside the first-type iron core 2111 and connected to the second outgoing lead 214 of the coil 2123. The first-phase connector 8821 and the second-phase connector 8822 are respectively located in two of the grooves 20111 on the outside of the first-type iron core 2111.

[0541] In some embodiments, in combination with Figure 78-Figure 86 As shown, the wiring assembly 2113 includes a long wiring assembly 21131, a medium wiring assembly 21132, and a short wiring assembly 21133. Among them, the long wiring assembly 21131, the medium wiring assembly 21132, and the short wiring assembly 21133 have the same functions and similar features. The length of the long wiring assembly 21131 is greater than the length of the medium wiring assembly 21132, and the length of the medium wiring assembly 21132 is greater than the length of the short wiring assembly 21133.

[0542] In some embodiments, in combination with Fig.78 、 Fig.79 and Fig.80 As shown, a first limiting feature 21151 is further provided on the insulating layer 2115 of the wiring assembly 2113 to facilitate the positioning of the wiring assembly 2113.

The length of the long outgoing line assembly 2161 is greater than the length of the short outgoing line assembly 2162.

[0544] In some embodiments, in combination with Figure 103-106 As shown, both the long outgoing line assembly 2161 and the short outgoing line assembly 2162 include a fourth insulating member 2163 and a fourth wire 2164. A wire clamping groove 2166 is formed at the bottom of the fourth insulating member 2163 and the fourth wire 2164. The groove 2166 is used to connect with the coil 2123.

[0545] In some embodiments, in combination with Figure 103-106 As shown, a second limiting feature 2165 is provided on the fourth insulating member 2163 to facilitate the positioning of the outgoing line assembly 216.

[0546] In some embodiments, in combination with Figure 107-Figure 110As shown, multiple second-type iron cores 2112, multiple long wiring components 21131, short wiring components 21133, and long outgoing wire components 2161 form the first-phase structure of the second component 210. In the first-phase structure, the first outgoing wire heads 2018 of the coils 2123 of each second-type iron core 2112 are in the same direction when viewed from top to bottom. The first outgoing wire heads 2018 of the upper coils 2123 of the first-layer second-type iron cores 2112 are connected to the first-phase lead 21211 through the fourth wire 2161 of the long outgoing wire component 2161 to form the first-phase winding outgoing wire structure. The first outgoing wire heads 2018 of the lower coils 2123 of the first-layer second-type iron cores 2112 are connected up and down to the first outgoing wire heads 2018 of the upper coils 2123 of the second-layer second-type iron cores 2112 through the conductive members 2114 of the first long wiring component 21131. The first outgoing wire heads 2018 of the lower coils 2123 of the second-layer second-type iron cores 2112 are connected up and down to the first outgoing wire heads 2018 of the upper coils 2123 of the third-layer second-type iron cores 2112 through the conductive members 2114 of the second long wiring component 21131, and so on, until the first outgoing wire heads 2018 of the lower coils 2123 of the last-layer second-type iron cores 2112 are connected to the first-phase connector 8821 of the bottom wiring device 880, thereby forming the first-phase structure of the second component 210.

[0547] In some embodiments, in combination with Figure 111-114 As shown, multiple second-type iron cores 2112, multiple long wiring components 21131, middle wiring components 21132, and short outgoing wire components 2162 form the second-phase structure of the second component 210. In the second-phase structure, the first outgoing wire heads 2018 of the coils 2123 of each second-type iron core 2112 are in the same direction when viewed from top to bottom and are staggered from the first-phase structure. Similar to the first-phase structure, the first outgoing wire heads 2018 of the upper coils 2123 of the first-layer second-type iron cores 2112 are connected to the second-phase lead 21212 through the fourth wire 2164 of the short outgoing wire component 2162 to form the second-phase winding outgoing wire structure. The first outgoing wire heads 2018 of the lower coils 2123 of the first-layer second-type iron cores 2112 are connected up and down to the first outgoing wire heads 2018 of the upper coils 2123 of the second-layer second-type iron cores 2112 through the conductive members 2114 of the first long wiring component 21131; the first outgoing wire heads 2018 of the lower coils 2123 of the second-layer second-type iron cores 2112 are connected up and down to the first outgoing wire heads 2018 of the upper coils 2123 of the third-layer second-type iron cores 2112 through the conductive members 2114 of the second long wiring component 21131, and so on, until the first outgoing wire heads 2018 of the lower coils 2123 of the last-layer second-type iron cores 2112 are connected to the second-phase connector 8822 of the bottom wiring device 880. Thereby, the second-phase structure of the second component 210 is formed.

[0548] In some embodiments, in combination with Figure 115-118 As shown, the first iron core unit 21114, a plurality of second - type iron cores 2112, the second iron core unit 21115, and a plurality of long wiring assemblies 21131 form the third - phase structure of the second assembly 210. In the third - phase structure, the first lead - out heads 2018 of each coil 2123 are in the same direction when viewed from top to bottom, and are staggered from the first - phase structure and the second - phase structure. In the third - phase structure, the first iron core unit 21114 is located on the first layer. The second lead - out head 214 of the coil 2123 of the first iron core unit 21114 is connected to the third - phase lead 21213 through the inner lead - out device 860, forming the third - phase winding lead - out structure. From the second layer to the penultimate layer are all composed of second - type iron cores 2112, and the last layer is the second iron core unit 21115. Among them, the first lead - out head 2018 of the lower - side coil 2123 of the second - type iron core 2112 on the first layer is connected up and down to the first lead - out head 2018 of the upper - side coil 2123 of the second - type iron core 2112 on the second layer through the conductive member 2114 of the first long wiring assembly 21131. The first lead - out head 2018 of the lower - side coil 2123 of the second - type iron core 2112 on the second layer is connected up and down to the first lead - out head 2018 of the upper - side coil 2123 of the second - type iron core 2112 on the third layer through the conductive member 2114 of the second long wiring assembly 21131, and so on, until the first lead - out head 2018 of the lower - side coil 2123 of the second - type iron core 2112 on the last layer is connected up and down to the first lead - out head 2018 of the coil 2123 of the bottom second iron core unit 21115 through the conductive member 2114 of the long wiring assembly 21131. The third - phase joint 8823 of the bottom wiring device 880 has been connected to the second lead - out head 214 of the coil 2123, thus forming the third - phase structure of the second assembly 210.

[0549] In summary, the outer edges of the wiring assembly 2113 and the lead - out assembly 216 in this embodiment do not exceed the outer boundary of the iron - core assembly 211, and both the wiring assembly 2113 and the lead - out assembly 216 have limiting features and can be positioned during assembly.

[0550] In some embodiments, in combination with Figure 119-Figure 122As shown, the wiring assembly 2113 includes a first connector 2117 and a second connector 2118. The first connector 2117 and the second connector 2118 are inserted and mated with each other, and both the first connector 2117 and the second connector 2118 are provided on the iron core assembly 211 and electrically connected to the coil 2123. That is to say, the wiring assembly 2113 is not limited to the way of forming the above embodiments. The wiring assembly 2113 may also include a first connector 2117 and a second connector 2118, and the first connector 2117 and the second connector 2118 are provided on the iron core assembly 211 and electrically connected to the coil 2123. In this way, when the first connector 2117 and the second connector 2118 are connected to external components, the electrical connection between the coil 2123 and the external structural member can be realized, and the connection difficulty of the coil 2123 can be reduced.

[0551] In some embodiments, one of the first connector 2117 and the second connector 2118 is a jack, and the other is a plug. The jack and the plug are inserted and mated with each other to facilitate the electrical connection between the coil 2123 and the external structural member and reduce the connection difficulty of the coil 2123.

[0552] It should be noted that the outgoing line structure of this embodiment refers to the relevant structure designed for the winding assembly 212 to lead out from the inside to the outside of the electromagnetic actuator 1000.

[0553] Among them, the second component 210 is a part of the stator assembly of the electromagnetic actuator 1000. The stator assembly is inside the whole structure and includes a connecting wire 2121, a wire passing channel 330, a central rod 300, a first limiting member 380, a winding assembly 212, an iron core assembly 211, a guiding bearing 840 and a limiting nut 850. Among them, the winding assembly 212 and the iron core assembly 211 form the second component 210 (for the specific structure of the electromagnetic actuator 1000, see Fig. 22 ).

[0554] In some embodiments, as shown in combination with Fig.119 , Fig.120 and Fig.121 , both the winding assembly 212 and the iron core assembly 211 are circular rings. The winding assembly 212 is assembled on both the upper and lower surfaces of the iron core assembly 211. The second component 210 is formed by stacking a plurality of winding assemblies 212 and iron core assemblies 211 one on top of the other (as shown in Fig.122 ). After stacking, it is sleeved on the central rod 300 and finally becomes cylindrical.

[0555] In some embodiments, three grooves 20111 are evenly distributed on the circumference of the iron core assembly 211. The three grooves 20111 respectively correspond to the three-phase lines of the motor. Three second connectors 2118 are provided on the iron core assembly 211. The winding of the winding assembly 212 passes through one of the second connectors 2118 and forms a first connector 2117, so as to realize the first connector 2117 on the iron core assembly 211, while the other two second connectors 2118 are through. The corresponding other side also has a second connector 2118 leading out, and the other two leading-out ports are through. The first connectors 2117 on both sides of the iron core assembly 211 respectively form a male-female end fitting with protrusions and depressions.

[0556] In some embodiments, the winding assembly 212 and the iron core assembly 211 are stacked in sequence according to the three phases A, B, and C, that is, the winding assemblies 212 of the same phase are not adjacent. Therefore, as Fig.122 shown, the first connector 2117 on one side of the iron core assembly 211 needs to pass through the iron core assemblies 211 of multiple other-phase winding assemblies 212 and be connected to the iron core assembly 211 of the winding assembly 212 of the same phase. Therefore, the first connector 2117 is relatively long.

[0557] It should be noted that in this embodiment, the connection of the winding assemblies 212 of the same phase is realized through the first connector 2117, so that the connection of the same-phase windings does not require welding, and is firm and reliable. Moreover, the first connector 2117 passing through from the inside of the iron core assembly 211 will not affect the relative movement between the second component 210 and the first component 220, thereby avoiding damage to the winding caused by the movement between the second component 210 and the first component 220 and ensuring the performance of the coil 2123.

[0558] In some embodiments, the connection lines 2121 respectively penetrate from above and exit from below the wire passing channel 330. Three pipe outlets are provided below the wire passing channel 330. There are three wire outlets 311 on the central rod 300. The three pipe outlets of the wire passing channel 330, the three wire outlets of the central rod 300, and the three second connectors 2118 on the iron core assembly 211 correspond one by one. During assembly, the wire passing channel 330 is arranged on the central rod 300, and the connection lines 2121 respectively pass through the wire passing channel 330 and the wire outlets 311 of the central rod 300.

[0559] Through the above settings, the wire leading-out process can be fixed. Among them, the central rod 300 plays a role in fixing and protecting the wiring, and well solves the problem of the risk of extrusion and scratching in the prior art here. In addition, a first limiting member 380 is sleeved on the upper part of the central rod 300. The first limiting member 380 and the outlet of the central rod 300 jointly fix the connection lines 2121. At the same time, the first limiting member 380 is made of rubber material and can buffer the impact of surrounding components on the connection lines 2121 under extreme working conditions, thereby playing a role in protecting the connection lines 2121 and ensuring the reliability of the electrical system.

[0560] In summary, for the wire outlet structure of the electromagnetic actuator 1000 in this embodiment, by utilizing the relative relationship of the surrounding components, a clever design is adopted to solve the problem of difficult wire outlet, which has the advantages of safety and reliability, convenient disassembly and assembly, and compact space design.

[0561] In some embodiments, as shown in Fig.60 、 Fig.61 and Fig.62 An insulating skeleton 213 is provided between the iron core assembly 211 and the winding assembly 212. A lead channel 2131 is provided on the axial end face of the insulating skeleton 213, and the lead channel 2131 extends radially along the iron core assembly 211. Among them, by providing the insulating skeleton 213 between the iron core assembly 211 and the winding assembly 212, the insulation cooperation between the iron core assembly 211 and the winding assembly 212 is realized, and the performance of the second component 210 is ensured.

[0562] At the same time, by providing the lead channel 2131 extending radially along the iron core assembly 211 on the axial end face of the insulating skeleton 213, it is convenient to lead out the lead wire 21231 of the coil 2123 to the outside of the iron core assembly 211, so as to facilitate the wiring of the coil 2123 and the connection of the power supply.

[0563] In some embodiments, as shown in Figure 123-Figure 127 The outer peripheral wall of the insulating skeleton 213 is provided with a plurality of wire grooves 2132 arranged at equal intervals, and at least one wire groove 2132 is communicated with the lead channel 2131. Thus, it is convenient to lead out the connecting wire 2121 connecting the coil 2123.

[0564] It should be noted that by providing the insulating skeleton 213 of this embodiment, the iron core assembly 211, the winding assembly 212 and the insulating skeleton 213 can all be formed into independent components, reducing the design difficulty of the iron core assembly 211, the winding assembly 212 and the insulating skeleton 213. At the same time, the insulating skeleton 213 of this embodiment has the advantages of low processing difficulty, convenient maintenance, simple structure and high consistency in both layout space and production efficiency.

[0565] In some embodiments, as shown in Figure 123-Figure 127 The insulating skeleton 213 mainly consists of a lead channel 2131, a second annular groove 2138 and a wire groove 2132.

[0566] In some embodiments, as shown in Fig.123 and Fig.126As shown, the insulating skeleton 213 is provided with six wire grooves 2132 on its circumference along the epitaxial direction. The positions of the six wire grooves 2132 are evenly distributed, that is, the interval between two grooves is 60°. A second annular groove 2138 is formed on the surface of the insulating skeleton 213. A winding space is formed between the second annular groove 2138, the inner side wall 2136 of the second annular groove 2138 and the outer side wall of the second annular groove 2138. The winding space is used for assembling the coil 2123.

[0567] In some embodiments, on the opposite side of the insulating skeleton 213 where the second annular groove 2138 is provided, there is a second boss structure 2134 formed by the lead channel 2131 and an insulating portion 2135 formed by the wire groove 2132. The second boss structure 2134 and the insulating portion 2135 are mainly used for nesting with the structural parts on the iron core assembly 211, greatly improving the space utilization rate and reducing the occupied volume of the parts. Therefore, the volume of the entire structure can be reduced, and the matching strength between the insulating skeleton 213 and the iron core assembly 211 can be ensured.

[0568] Through the above settings, during use, the iron core assembly 211, the winding assembly 212 and the insulating skeleton 213 are assembled and combined into a single module (as Fig.127 shown). Among them, the insulating skeleton 213 is nested in the first annular groove 21111 on the surface of the iron core assembly 211. The second boss structure 2134 of the insulating skeleton 213 is combined with the wire groove 2013 in the first annular groove 21111, and the insulating portion 2135 formed by the wire groove 2132 is aligned with the groove 20111 in the circumferential direction of the iron core assembly 211, so that the coil 2123 has a larger operating space when conducting series wiring outside the iron core assembly 211, which is beneficial to the subsequent welding wiring between the coils 2123 and is convenient for operation.

[0569] It should be noted that in some embodiments, since the second component 210 is stacked by individual modules, and the module is assembled by the iron core assembly 211, the winding assembly 212 and the insulating skeleton 213. The module located at the end of the second component 210 only has the winding assembly 212 and the insulating skeleton 213 on one side. The winding assembly 212 and the insulating skeleton 213 are provided at both ends of the iron core assembly 211 of the module located in the axial middle of the second component 210. When accessing a three-phase power supply, the coils 2123 of the winding assembly 212 of the same module are of the same phase, and the lead and outlet positions of the coils 2123 differ by 180°. The leads of the coils 2123 pass through the lead channel 2131 on the insulating skeleton 213, and then pass through the wire groove 2132 and extend to the outer periphery of the iron core assembly 211. The series wiring inside the module is carried out at the part where the wire grooves 2132 of the two insulating skeletons 213 are connected, and the wiring is carried out by welding. Wiring at the wire groove 2132 has a larger operating space.

[0570] Meanwhile, since the lead channel 2131 is provided on the surface of the insulating skeleton 213, the structure of the insulating skeleton 213 is unique, which can effectively avoid assembly and wiring errors and improve production efficiency.

[0571] In some embodiments, when accessing a three-phase power supply, not only is it necessary to connect the winding coils in series inside the module, but also the modules accessing the same-phase power supply need to be connected in series. Both the interval angle between the leads and the interval angle between the leads and the outgoing wires are multiples of 60°. Therefore, six evenly distributed wire grooves 2132 are provided along the circumferential direction of the outer extension of the insulating skeleton 213, which improves the versatility and utilization rate of the parts, can greatly increase production efficiency, save costs, and contribute to mass production.

[0572] In some embodiments, an assembly hole 2137 is provided at the center of the insulating skeleton 213 to facilitate the assembly and cooperation between the insulating skeleton 213 and the iron core assembly 211. Axially, the outer edge of the insulating skeleton 213 protrudes from the first annular groove 21111, and the inner edge of the insulating fixing 213 protrudes from the first annular groove 21111, thereby realizing the insulation between the coil winding and the stator iron core.

[0573] In some embodiments, the inner side wall 2136 surrounds the outer circumference of the assembly hole 2137 to form a hollow cylinder with a certain wall thickness between the assembly hole 2137 of the insulating skeleton 213 and the second annular groove 2138.

[0574] In some embodiments, a stepped limiting platform is provided on the surface of the hollow cylinder. The adjacent two out-of-phase coils 2123 are separated by an insulating paper 2122, and the insulating paper 2122 is nested on the hollow cylinder with a thinner wall thickness to facilitate the fixing of the insulating paper 2122, and the structure is compact and the material utilization rate is high.

[0575] In some embodiments, the central rod 300 is provided with a first limiting structure, and the iron core assembly 211 is provided with a limiting portion. The limiting portion cooperates with the first limiting structure to limit the rotation of the iron core assembly 211 relative to the central rod 300. The position stability of the iron core assembly 211 is improved, and under the coupling and cooperation of the first component 220 and the second component 210, the central rod 300 and the housing 100 can effectively produce relative movements to ensure the working performance of the electromagnetic actuator 1000.

[0576] In some embodiments, the limiting portion on the iron core assembly 211 can be understood as the positioning protrusion 21415 in the above text.

[0577] In some embodiments, a cylindrical pin is provided between the iron core assembly 211 and the central rod 300 to limit the rotation of the iron core assembly 211 relative to the central rod 300.

[0578] In some embodiments, in combination with Figure 128-Figure 131 as shown, the central rod 300 is provided with a first positioning portion 340 (for the specific structure of the first positioning portion 340, reference can be made to Fig.25 ), the iron core assembly 211 is provided with a second positioning portion 350, and the first positioning portion 340 and the second positioning portion 350 cooperate to make the central rod 300 and the iron core assembly 211 relatively stationary. Thereby, circumferential limitation of the iron core assembly 211 and the central rod 300 is achieved, rotation of the iron core assembly 211 around the central rod 300 is avoided, and the working performance of the iron core assembly 211 is ensured.

[0579] In some embodiments, in combination with Figure 128-Figure 131 as shown, the first positioning portion 340 is formed as a groove provided on the outer peripheral wall of the central rod 300, the second positioning portion 350 is formed as a groove provided on the iron core assembly 211, and the anti-rotation rod 360 is provided between the first positioning portion 340 and the second positioning portion 350. To limit the positions of the central rod 300 and the iron core assembly 211, make the central rod 300 and the iron core assembly 211 relatively stationary, reduce the difficulty of limiting the central rod 300 and the iron core assembly 211, and at the same time ensure that the wire outlet of the coil 2123 is consistent with the designed state.

[0580] It should be noted that through the above settings, it is also possible to avoid the problem that when the central rod 300 cooperates with the tower top, the iron core assembly 211 rotates around the central axis of the central rod 300 together with the assembly nut 830, resulting in inability to tighten.

[0581] In some embodiments, in combination with Figure 132-136 as shown, the electromagnetic actuator 1000 further includes a first limiting member 380 and a second limiting member 390. The first limiting member 380 and the second limiting member 390 are axially spaced along the central rod 300 and are respectively abutted against the iron core assembly 211 to limit the axial displacement of the iron core assembly 211. Thereby, movement of the iron core assembly 211 relative to the central rod 300 along the axial direction of the central rod 300 is avoided. In this way, it is convenient to more stably arrange the iron core assembly 211 on the central rod 300, avoid the magnetic core 211 from falling off the central rod 300, and thus ensure the installation stability and reliability of the iron core assembly 211 on the central rod 300.

[0582] In some embodiments, in combination with Figure 132-136 as shown, the first limiting member 380 and the second limiting member 390 are respectively adapted to abut against the inner wall of the housing 100 to limit the movement range of the housing 100. Here, it means that during the movement of the housing 100, the first limiting member 380 and the second limiting member 390 can respectively abut against the inner wall of the housing 100, thereby limiting the movement range of the housing 100, ensuring the position stability of the movement of the housing 100, and thus ensuring the working performance of the electromagnetic actuator 1000.

[0583] In some embodiments, in combination with Figure 132-136 As shown, one of the first limiting member 380 and the second limiting member 390 is an integral part with the central rod 300 and the other is a separate part from the central rod 300. The integral part can reduce the number of components of the electromagnetic actuator 1000 and lower the complexity of the structure of the electromagnetic actuator 1000.

[0584] In some embodiments, in combination with Fig.132 and Fig.133 As shown, the first limiting member 380 is an integrally formed part with the central rod 300. Since the relative position between the first limiting member 380 and the central rod 300 is unchanged, when the iron core assembly 211 is sleeved on the central rod 300, it is convenient to realize the cooperation between the first limiting member 380 and the iron core assembly 211, so as to use the first limiting member 380 to limit the position of the iron core assembly 211 in the axial direction of the central rod 300.

[0585] In some embodiments, in combination with Fig.132 and Fig.133 As shown, the central rod 300 is provided with a convex portion protruding radially outward to define the first limiting member 380, so that the first limiting member 380 is an integrally formed part with the central rod 300, and the connection between the first limiting member 380 and the central rod 300 is omitted.

[0586] In some embodiments, the other of the first limiting member 380 and the second limiting member 390 is in threaded cooperation with the central rod 300. Here, it means that when one of the first limiting member 380 and the second limiting member 390 is an integral part with the central rod 300, the other of the first limiting member 380 and the second limiting member 390 is in threaded cooperation with the central rod 300 to realize the fixed connection between the other of the first limiting member 380 and the second limiting member 390 and the central rod 300, ensure the position stability of the other of the first limiting member 380 and the second limiting member 390, and thus facilitate the cooperation between the first limiting member 380 and the second limiting member 390 to limit the axial displacement of the iron core assembly 211.

[0587] In some embodiments, the second limiting member 390 is formed as a threaded member, and the threaded member is in threaded cooperation with the central rod 3000 so as to be able to detachably arrange the second limiting member 390 on the central rod 300.

[0588] In some embodiments, in combination with Fig.132 and Fig.134As shown, the other of the first limiting member 380 and the second limiting member 390 includes a first part 391 and a second part 392. The first part 391 cooperates with the central rod 300. In the radial direction of the central rod 300, the second part 392 is located radially outside the first part 391; in the axial direction of the central rod 300, the axial length of the first part 391 is greater than the axial length of the second part 392. A part of the second part 392 abuts against the iron core assembly 211 and another part is spaced apart from the iron core assembly 211. Among them, by setting the axial length of the first part 391 to be greater than the axial length of the second part 392, the area of cooperation between the first part 391 and the central rod 300 is increased, so as to facilitate firmly setting the other of the first limiting member 380 and the second limiting member 390 on the central rod 300. And because the iron core assembly 211 contains wire outlet grooves and wire harnesses, by setting the axial length of the first part 391 to be greater than the axial length of the second part 392, the axial length of the second part 392 can also be made smaller, which is convenient for avoiding the wire harness.

[0589] At the same time, by locating the second part 392 radially outside the first part 391, it is convenient to achieve the abutment of a part of the second part 392 against the iron core assembly 211, so as to limit the axial displacement of the iron core assembly 211 by using the other of the first limiting member 380 and the second limiting member 390.

[0590] In addition, by spacing another part of the second part 392 from the iron core assembly 211, it is beneficial to the heat dissipation of the iron core assembly 211, and there is a gap between another part of the second part 392 and the iron core assembly 211, which plays a role in avoiding stress concentration.

[0591] It should be explained here that in terms of the axis of the central rod 300, the first part 391 is closer to the central rod 300, and the second part 392 is farther from the central rod 300. Therefore, in the radial direction of the central rod 300, the second part 392 is located radially outside the first part 391.

[0592] In some embodiments, as shown in combination with Fig.135 and Fig.136 The other of the first limiting member 380 and the second limiting member 390 is installed at the end of the central rod 300 and a part extends into the central rod 300, so as to detachably set the other of the first limiting member 380 and the second limiting member 390 in the central rod 300. After sleeving the iron core assembly 211 on the central rod 300 along the axial direction of the central rod 300, at least one of the first limiting member 380 and the second limiting member 390 is installed on the central rod 300 to limit the axial displacement of the iron core assembly 211 along the central rod 300 after the iron core assembly 211 is installed in place.

[0593] In some embodiments, the second part 392 of the other one of the first limiting member 380 and the second limiting member 390 is formed into a mounting structure with a buffer member. In this way, while realizing the fixed installation of the other one of the first limiting member 380 and the second limiting member 390 to the central rod 300, the other one of the first limiting member 380 and the second limiting member 390 can also play a buffering role.

[0594] In some embodiments, the first limiting member 380 and the second limiting member 390 are made of rubber material so that the first limiting member 380 and the second limiting member 390 can play a buffering role.

[0595] In some embodiments, in combination Fig.135 and Fig.136 As shown, the second limiting member 390 is installed at the end of the central rod 300 and a part of it extends into the central rod 300. The second limiting member 390 includes a piston part 393. The piston part 393 is made of an elastic material. When the piston part 393 is extended into the central rod 300, the piston part 393 undergoes elastic deformation and is compressed to have an interference fit with the inside of the central rod 300, so as to fix the piston part 393 on the central rod 300.

[0596] Wherein, a part of the structure of the second limiting member 390 protrudes radially from the piston part 393 along the central rod 300, and a part of the structure of the second limiting member 390 cooperates with the iron core assembly 211 to limit the displacement of the iron core assembly 211 in the axial direction of the central rod 300.

[0597] In some embodiments, the first limiting member 380 and the second limiting member 390 are also formed into a limiting assembly of the second assembly 210 to limit the relative displacement of the second assembly 210.

[0598] In some embodiments, during the operation of the electromagnetic actuator 1000, the iron core assembly 211 and the housing 100 will have a relative linear motion. The first limiting member 380 can simultaneously play the role of the lower limit for restricting the movement of the housing 100, and the second limiting member 390 can simultaneously play the role of the upper limit for restricting the movement of the housing 100.

[0599] In a specific embodiment, the first limiting member 380 plays the role of restricting the press-fitting depth of the iron core assembly 211. After the press-fitting is completed, the second limiting member 390 is then connected to the bottom of the central rod 300 to play the role of preventing the iron core assembly 211 from falling off axially downward.

[0600] It should be noted that the specific implementation forms of the first limiting member 380 and the second limiting member 390 include but are not limited to forms such as nuts, pistons, and integrated stepped surfaces.

[0601] In some embodiments, in combination Fig.128 、 Fig.129 and Fig.130 As shown in Fig.130 , at least one cooling chamber 320 for accommodating a cooling medium is provided in the central rod 300, so that the cooling medium can be filled in the central rod 300, facilitating the use of the cooling medium to dissipate heat from the iron core assembly 211, thereby ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoiding damage to the components inside the electromagnetic actuator 1000.

[0602] In some embodiments, the inner wall of the central rod 300 is hollow to form the cooling chamber 320. Before assembly, the cooling medium is added from the filling port 323 (for the specific structure of the filling port 323, reference can be made to Fig.25 ), and then the filling port 323 is sealed to make the cooling chamber 320 a sealed cavity. When the electromagnetic actuator 1000 operates, the heat on the iron core assembly 211 is transferred to the cooling medium through the central rod 300, and the cooling medium transfers the heat to the air through the cold and heat exchange cycle, thereby ensuring the long-term and efficient operation of the electromagnetic actuator 1000 and avoiding damage to the internal components.

[0603] At the same time, this design does not add extra components such as cooling pipes, and the entire cooling scheme has a compact structure.

[0604] In some embodiments, at least a part of the cooling chamber 320 coincides with the iron core assembly 211 in the radial projection. Thus, at least a part of the cooling chamber 320 can be directly opposite to the iron core assembly 211 in the radial direction, facilitating the use of the cooling medium in the cooling chamber 320 to dissipate heat from the iron core assembly 211, thereby ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoiding damage to the components inside the electromagnetic actuator 1000.

[0605] In some embodiments, at least a part of the cooling chamber 320 is located outside the accommodating chamber 130. On the one hand, it is convenient to transport the cooling medium towards the cooling chamber 320, and on the other hand, it is also beneficial to cool down the cooling medium and ensure the heat dissipation performance of the cooling medium.

[0606] In some embodiments, the electromagnetic actuator 1000 further includes a first cooling pipe. The first cooling pipe is disposed in the cooling chamber 320, and a first cooling cavity is formed between the first cooling pipe and the cooling chamber 320. One of the first cooling cavity and the first cooling pipe is adapted to communicate with the first water inlet, and the other is adapted to communicate with the first water outlet (not shown in this example figure). In this way, the cooling medium can circulate between the first cooling cavity and the first cooling pipe, thus facilitating the use of the cooling medium to dissipate heat from the iron core assembly 211 and ensuring the heat dissipation performance of the cooling medium.

[0607] In some embodiments, the first cooling pipe is spaced from the inner wall of the cooling chamber 320, so that a connection channel is formed between the first cooling pipe and the cooling chamber 320. The connection channel is used to connect the first cooling chamber and the first cooling pipe. In this way, when one of the first cooling chamber and the first cooling pipe is connected to the first water inlet and the other is connected to the first water outlet, it can ensure that the cooling medium between the first water inlet and the first water outlet can flow through the first cooling chamber and the first cooling pipe in sequence, which is beneficial to realizing the circulating flow of the cooling medium, so as to facilitate the use of the cooling medium to dissipate heat from the iron core assembly 211.

[0608] In some embodiments, in combination Figure 137-Figure 140 As shown, the electromagnetic actuator 1000 further includes a second cooling pipe 32111 and a third cooling pipe 32121. Both the second cooling pipe 32111 and the third cooling pipe 32121 are arranged in the cooling chamber 320 and communicate with the cooling chamber 320. One of the second cooling pipe 32111 and the third cooling pipe 32121 is adapted to be connected to the second water inlet 3211, and the other is adapted to be connected to the second water outlet 3212. In this way, the cooling medium can enter the cooling chamber 320 through the second water inlet 3211 and be discharged from the cooling chamber 320 through the second water outlet 3212, which is beneficial to realizing the circulating flow of the cooling medium.

[0609] In some embodiments, in combination Fig.138 and Fig.139 As shown, the second cooling pipe 32111 is connected to the second water inlet 3211, and the third cooling pipe 32121 is connected to the second water outlet 3212. In this way, the cooling medium can enter the cooling chamber 320 through the second cooling pipe 32111 and be discharged from the cooling chamber 320 through the third cooling pipe 32121, which is beneficial to realizing the circulating flow of the cooling medium.

[0610] In some embodiments, in combination Fig.139 and Fig.140 As shown, there are multiple cooling chambers 320, including a first cooling chamber 321 and a second cooling chamber 322. In the axial direction of the central rod 300, the first cooling chamber 321 is located on one side of the iron core assembly 211, and at least part of the second cooling chamber 322 is disposed opposite to the iron core assembly 211. Thus, at least part of the cooling chamber 320 overlaps with the iron core assembly 211 in the radial direction, which is convenient for using the cooling medium in the cooling chamber 320 to dissipate heat from the iron core assembly 211, so as to ensure that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the components inside the electromagnetic actuator 1000.

[0611] Through the unfamiliar setting, the first cooling chamber 321 and the second cooling chamber 322 can be used to dissipate heat from different parts of the electromagnetic actuator 1000 respectively, interact with each other, and finally ensure that the electromagnetic actuator 1000 operates efficiently. The central rod 300 plays a role in quickly conducting and dissipating heat during the entire cooling process.

[0612] In some embodiments, the second cooling chamber 322 is formed as a closed chamber and filled with a cooling medium.

[0613] In some embodiments, in combination Fig.139 and Fig.140 As shown, there are multiple second cooling chambers 322, which are arranged at intervals along the circumferential direction of the central rod 300. Each second cooling chamber 322 includes multiple sub-chambers 3221 arranged at intervals along the circumferential direction of the central rod 300. To ensure the heat dissipation performance of the cooling chamber 320.

[0614] In some embodiments, axially on the central rod 300, the ends of the multiple sub-chambers 3221 of each second cooling chamber 322 are communicated. So that the cooling medium in each second cooling chamber 322 can circulate between the multiple sub-chambers 3221 to ensure the heat dissipation performance of the second cooling chamber 322.

[0615] In some embodiments, at least part of the structure of the cooling chamber 320 is formed as a heat pipe. So that the cooling chamber 320 itself has the ability to dissipate heat, thereby reducing the temperature of the cooling medium and ensuring the cooling effect of the cooling medium.

[0616] In some embodiments, a cooling structure 810 is provided on the central rod 300 (for the specific structure of the cooling structure 810, see Fig. 22 ). The cooling structure 810 is provided on the part of the central rod 300 extending out of the receiving chamber 130. To facilitate using the cooling structure 810 to reduce the temperature of the cooling medium and ensure the cooling effect of the cooling medium.

[0617] In some embodiments, the cooling structure 810 includes a radiator. To improve the heat dissipation performance of the cooling structure 810, thereby using the cooling structure 810 to reduce the temperature of the cooling medium and ensure the cooling effect of the cooling medium.

[0618] In some embodiments, the cooling structure 810 includes a cooling pipeline, and a third water inlet and a third water outlet communicating with the outside are formed on the cooling pipeline. The third water inlet and the third water outlet are used to convey the cooling medium with a lower external temperature into the cooling structure 810, thereby reducing the temperature of the cooling medium in the cooling structure 810. In this way, the heat dissipation performance of the cooling structure 810 can also be ensured, so that the cooling structure 810 can effectively reduce the temperature of the cooling medium and ensure the cooling effect of the cooling medium.

[0619] In some embodiments, such as Fig.137 As shown, a guide rod 400 is provided on the housing 100, and a guide hole 310 is formed on the central rod 300. The guide rod 400 is engaged with the guide hole 310. This is to prevent the housing 100 from shifting during movement, that is, to ensure that the housing 100 can move along a predetermined direction and guarantee the accuracy of the movement of the housing 100.

[0620] In some embodiments, a cooling cavity is provided on the guide rod 400, and the cooling cavity is adapted to accommodate a coolant. In this way, the coolant can be used to further dissipate heat from the iron core assembly 211, so as to ensure that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the components inside the electromagnetic actuator 1000.

[0621] In some embodiments, the volume of the cooling cavity is larger than the volume of the coolant. That is to say, the coolant does not fill the entire cooling cavity, enabling the coolant in the cooling cavity to undergo a gas-liquid transformation process and ensuring the cooling performance of the coolant.

[0622] In some embodiments, the projection of the cooling cavity in the radial direction coincides with at least a part of the iron core assembly 211. Thus, the cooling cavity can be directly opposite the iron core assembly 211 in the radial direction, facilitating the use of the coolant in the cooling cavity to dissipate heat from the iron core assembly 211, further ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoiding damaging the components inside the electromagnetic actuator 1000.

[0623] In some embodiments, there is a partial overlap between the projection of the iron core assembly 211 that coincides with the projection of the cooling cavity in the radial direction and the projection of the cooling cavity 320 in the radial direction. That is to say, a part of the iron core assembly 211 is directly opposite the cooling cavity on the guide rod 400 and the cooling cavity 320 on the central rod 300 at the same time, maximizing the heat dissipation performance of the iron core assembly 211.

[0639] Next, the suspension system 10000 of the embodiments of the present invention will be described with reference to the accompanying drawings of the specification.

[0640] Combined Fig.174 and Fig.175 shown, a suspension system 10000 according to an embodiment of the present invention includes: a vibration damping device 5000.

[0641] Wherein, the vibration damping device 5000 is the aforementioned vibration damping device 5000, and the specific structure of the vibration damping device 5000 will not be elaborated here.

[0642] From the above structure, it can be seen that for the suspension system 10000 of the embodiments of the present invention, by adopting the aforementioned vibration damping device 5000, the working performance of the suspension system 10000 can be ensured.

[0643] In some embodiments, at least one wheel 2000 is adapted to be correspondingly arranged with a shock absorber 5000. So as to utilize the shock absorber 5000 to buffer the impact transmitted by the road surface, and at the same time, the noise input from the road surface and the wheel 2000 can be isolated to ensure the comfort of the vehicle.

[0644] In some embodiments, the suspension system 10000 further includes a controller, and the controller is adapted to control the electromagnetic actuator 1000. So that the electromagnetic actuator 1000 can effectively operate to buffer the impact transmitted by the road surface, and at the same time, the noise input from the road surface and the wheel 2000 can be isolated to ensure the comfort of the vehicle.

[0645] In some embodiments, a plurality of wheels 2000 are adapted to be correspondingly arranged with shock absorbers 5000. That is to say, a corresponding shock absorber 5000 is provided for each of the plurality of wheels 2000, so as to utilize the shock absorber 5000 to buffer the impact transmitted by the road surface, and at the same time, the noise input from the road surface and the wheel 2000 can be isolated to ensure the comfort of the vehicle.

[0646] In some embodiments, the suspension system 10000 further includes a controller, and the controller is adapted to control a plurality of wheels 2000. So that the plurality of corresponding shock absorbers 5000 can buffer the impact transmitted by the road surface to ensure the comfort of the vehicle.

[0647] In some embodiments, the suspension system 10000 further includes a plurality of controllers, and the plurality of controllers are arranged in one-to-one correspondence with the plurality of wheels 2000. Here, it means that each wheel 2000 corresponds to a controller, so as to utilize the controller to separately control the shock absorber 5000 corresponding to the wheel 2000 and ensure the performance of the shock absorber 5000.

[0648] In some embodiments, the suspension system 10000 further includes a plurality of controllers, and one controller is adapted to control at least one wheel 2000. That is to say, one controller can control one wheel 2000 or a plurality of wheels 2000, so that the shock absorber 5000 corresponding to each wheel 2000 can operate to ensure the performance of the shock absorber 5000.

Furthermore, the extreme displacement amount of the leaf spring 3000 in the up and down direction during buffering deformation is increased, so that when the vehicle wheel 2000 jumps upward, it is not easy to interfere with structures such as the subframe 6000, thus well alleviating the fatigue damage of the leaf spring 3000, enabling the leaf spring 3000 to stably perform buffering operations, and making the service life of the leaf spring 3000 longer.

[0652] In some embodiments, in the vehicle height direction, the distance from the first mounting point to the second mounting point is greater than the maximum deflection of the leaf spring 3000 at the second mounting point. This enables the leaf spring 3000 to stably be within a good tensile deformation range during use, thus well delaying the fatigue damage of the leaf spring 3000 and enhancing the service life of the leaf spring 3000.
