[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference below Figure 1-Figure 8The steering feel simulation device 10 according to an embodiment of the utility model is described. The steering feel simulation device 10 is used to simulate the feel of a vehicle steering system to ensure the driver's intuitive feeling and safety in controlling the vehicle while driving.

[0033] Reference Figure 1-Figure 8 As shown, the steering feel simulation device 10 according to an embodiment of the present invention includes: a motor unit 1 and a control unit 2, the control unit 2 includes a power board 21 and a control board 22, the power board 21 and the control board 22 are stacked, the power board 21 is connected to the three-phase terminal 11 of the motor unit 1, the power board 21 is suitable for being connected to a power source, the power board 21 is also suitable for being connected to a torque sensor of a vehicle steering wheel mechanism, the power board 21 is provided with a first connector 211, the control board 22 is provided with a second connector 221, the first connector 211 and the second connector 221 are plugged together to connect the power board 21 and the control board 22.

[0034] The power board 21 and the three-phase terminal 11 of the motor unit 1 are fixedly connected so that the relative positions of the power board 21 and the motor unit 1 remain unchanged, and the power board 21 and the motor unit 1 are electrically connected so that current, electrical signals, etc. can be transmitted between the power board 21 and the motor unit 1. The power board 21 has a power plug terminal 212, which is suitable for being electrically connected to a power source, and the power source supplies power to the steering feel simulation device 10 through the power plug terminal 212. The power board 21 also has a sensor plug terminal 213, which is suitable for being plugged and connected with a torque sensor of a vehicle steering wheel mechanism.

[0035] The torque sensor is used to detect the torque of the torsion bar of the vehicle steering wheel mechanism. The torque sensor can transmit the detected torque information in the form of an electrical signal to the power board 21 through the sensing connector 213 , and the power board 21 can transmit the torque information to the control board 22 .

[0036] By stacking the power board 21 and the control board 22, the control unit 2 can be made compact, which is beneficial to reducing the volume of the control unit 2 and reducing the space occupied by the control unit 2, thereby helping to reduce the space occupied by the steering feel simulation device 10 in the vehicle and reduce the probability of interference between the steering feel simulation device 10 and other components in the vehicle. In addition, by plugging and matching the first connector 211 and the second connector 221, the power board 21 and the control board 22 can be reliably connected.

[0037] The torque information detected by the torque sensor is transmitted to the controller on the control board 22 through the power board 21. The controller analyzes the received torque information to generate a feedback electrical signal, which is transmitted to the power board 21. The power board 21 receives the feedback electrical signal and drives the motor unit 1 to work. The rotor of the motor unit 1 rotates to apply a force opposite to the direction of rotation of the steering wheel. For example, when the driver turns the steering wheel, the driver will feel the reaction force from the steering wheel. This simulates the feel of the vehicle steering system, allowing the driver to intuitively feel the control of the vehicle, improve the driver's driving experience, and ensure the driver's safety.

[0038] According to some embodiments of the present invention, Figure 5 and Figure 6 As shown, a first connector 211 may be provided on a surface of the power board 21 facing the control board 22 , and a second connector 221 may be provided on a surface of the control board 22 facing the power board 21 .

[0039] Among them, the power board 21 and the control board 22 correspond and are arranged in a stacked manner, the first connector 211 is arranged on the surface of the power board 21 facing the control board 22, and the second connector 221 is arranged on the surface of the control board 22 facing the power board 21, and the first connector 211 and the second connector 221 are suitable for plug-in matching so that the power board 21 and the control board 22 are fixedly connected, and the first connector 211 and the second connector 221 are electrically connected.

[0040] By plugging and fitting the first connector 211 and the second connector 221, the power board 21 and the control board 22 can be stably and reliably connected to ensure that the power board 21 and the control board 22 do not undergo relative displacement during operation. At the same time, the first connector 211 and the second connector 221 are electrically connected, so that current, electrical signals, etc. can be transmitted between the power board 21 and the control board 22. In addition, the plugging and fitting of the first connector 211 and the second connector 221 facilitates the assembly of the power board 21 and the control board 22, thereby simplifying the production process and improving the production rhythm.

[0041] According to some embodiments of the present invention, Figure 4 , Figure 5 and Figure 8 As shown, the power board 21 may be provided with a sensor 214, the motor unit 1 may have a position sensing component 12, the sensor 214 and the position sensing component 12 may be arranged relative to each other, the sensor 214 and the control board 22 may be communicatively connected, and the sensor 214 is used to sense the position sensing component 12 to send the motor rotor position information of the motor unit 1 to the control board 22.

[0042] Among them, the position sensing component 12 can be a rotor position sensing magnet. When the motor rotor rotates, it can rotate synchronously with the position sensing component 12. The position sensing component 12 can detect the position of the motor rotor relative to the stator winding. The sensor 214 can sense the change in the rotation angle of the position sensing component 12. The sensor 214 can be communicatively connected with the control board 22. The sensor 214 can send the motor rotor position information of the motor unit 1 to the control board 22. Through the cooperation of the position sensing component 12 and the sensor 214, the motor rotor position information can be converted into an electrical signal that can be received by the control board 22, so that the control board 22 can accurately detect the torque applied to the steering wheel by the steering feel simulation device 10.

[0043] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the power board 21 may be formed with a three-phase pad 215 , and the three-phase pad 215 is connected to the three-phase terminal 11 .

[0044] The three-phase welding pad 215 is fixedly connected to the three-phase terminal 11, and the three-phase welding pad 215 is welded to the three-phase terminal 11. Further, the three-phase welding pad 215 can form a hole structure, and the three-phase terminals 11 are respectively inserted into the corresponding hole structures, and then the three-phase welding pad 215 is welded to the three-phase terminal 11, so that the three-phase welding pad 215 and the three-phase terminal 11 can be stably and reliably connected to ensure that the three-phase welding pad 215 and the three-phase terminal 11 do not have relative displacement during operation. At the same time, the three-phase welding pad 215 is connected to the three-phase terminal 11 to achieve the electrical connection effect between the power board 21 and the motor unit 1, so that current, electrical signals, etc. can be transmitted between the power board 21 and the motor unit 1. In addition, by setting the three-phase welding pad 215, it is beneficial to connect the power board 21 with the motor unit 1, so as to simplify the production process and improve the production rhythm.

[0045] According to some embodiments of the present invention, Figure 1 As shown, the motor unit 1 is located on the side of the control board 22 away from the power board 21. Along the arrangement direction of the power board 21 and the control board 22, the three-phase terminal 11 and the control board 22 are staggered. The control board 22 can avoid the three-phase welding pad 215 and the three-phase terminal 11, so that the three-phase welding pad 215 and the three-phase terminal 11 can be more convenient to connect, so as to ensure that the structural layout of the steering feel simulation device 10 is compact and reasonable, improve the space utilization rate, and also help to reduce the volume of the control board 22 and reduce the manufacturing materials of the control board 22, thereby saving costs.

[0046] According to some embodiments of the present invention, Figure 2 , Figure 3 and Figure 8As shown, the steering feel simulation device 10 further includes: a housing 3 , the motor unit 1 and the control unit 2 are both arranged in the housing 3 , and the power board 21 is fixed with a connector, which is passed through the housing 3 to extend out of the housing 3 .

[0047] The shell 3 can be made of metal aluminum or aluminum alloy. The shell 3 forms an installation space. The motor unit 1 and the control unit 2 can be arranged in the installation space of the shell 3. The shell 3 can include a shell 1 31 and a shell 2 32. The shell 1 31 and the shell 2 32 are suitable for being connected by bolts. The bolt connection has the advantages of strong load-bearing capacity, high reliability, easy disassembly and large load-bearing capacity.

[0048] The housing 1 31 can be located on the side of the control unit 2 facing away from the motor unit 1, and the housing 2 32 can be located on the side of the motor unit 1 facing away from the control unit 2. The power board 21 is fixed with a connector, and there are multiple connectors. The multiple connectors include a power plug-in terminal 212 and a sensor plug-in terminal 213. The connector is penetrated through the housing 1 31 to extend out of the housing 1 31 to ensure that when the housing 1 31 and the housing 2 32 are matched and connected, the connector can be connected to the power supply and the torque sensor. This arrangement has a simple structure and a good connection effect.

[0049] The outer shell 1 31 may have a screw hole 9 311, a screw hole 10 312, and a screw hole 11 313, and the outer shell 2 32 may have a screw hole 13 321, a screw hole 14 322, a screw hole 15 323, a screw hole 16 324, a screw hole 17 325, a screw hole 18 326, a screw hole 19 327, a screw hole 20 328, a screw hole 21 329, a screw hole 22 3210, and a screw hole 23 3211. The outer shell 1 31 may be bolted to the outer shell 2 32 through the correspondingly arranged screw hole 9 311 and screw hole 22 3210, screw hole 10 312 and screw hole 19 327, screw hole 11 313, and screw hole 16 324.

[0050] The power board 21 has screw hole one 216, screw hole two 217, screw hole three 218 and screw hole four 219. The power board 21 can be bolted to the housing 2 32 through the correspondingly arranged screw hole one 216 and screw hole twenty-one 329, screw hole two 217 and screw hole eighteen 326, screw hole three 218 and screw hole fourteen 322, screw hole four 219 and screw hole seventeen 325.

[0051] The control panel 22 has screw hole five 222, screw hole six 223, screw hole seven 224 and screw hole eight 225. The control panel 22 can be bolted to the housing two 32 through the correspondingly arranged screw hole five 222 and screw hole twenty-three 3211, screw hole six 223 and screw hole twenty 328, screw hole seven 224 and screw hole fifteen 323, screw hole eight 225 and screw hole thirteen 321.

[0052] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the housing 3 is formed with an inserting hole 314 , and the connector is inserted into the inserting hole 314 .

[0053] The shell 131 is formed with a plurality of plug holes 314, and the connectors are inserted into the plurality of plug holes 314 and can be connected to a power source and a torque sensor. The number of the connectors is equal to the number of the plug holes 314 and corresponds one to one. That is to say, each connector has a one-to-one corresponding plug hole 314. By inserting the connectors into the plug holes 314, the connectors can abut against the inner wall of the corresponding plug hole 314 for limiting position, which is beneficial to improving the relative position fixing effect between the shell 131 and the power board 21, and can reduce the probability of relative displacement between the power board 21 and the shell 131, so as to facilitate the coordinated assembly of the shell 131 and the power board 21, and is beneficial to simplifying the assembly process, improving the assembly efficiency of the shell 131 and the power board 21, and improving the production rhythm.

[0054] According to some embodiments of the present invention, Figure 3 As shown, a heat dissipation portion 315 is formed on the inner surface of the housing 3 , and the heat dissipation portion 315 abuts against the power board 21 .

[0055] The heat dissipation portion 315 can be constructed as a convex structure, and the heat dissipation portion 315 abuts against the power board 21. Specifically, the heat dissipation portion 315 abuts against the power device on the power board 21. The heat dissipation portion 315 can dissipate heat for the power board 21. The heat on the power board 21 can be conducted to the housing 3 through the heat dissipation portion 315. The heat is dissipated through the housing 3, which improves the heat dissipation efficiency of the power board 21, thereby improving the heat dissipation performance of the steering feel simulation device 10, which is beneficial to improving the working performance of the steering feel simulation device 10. It should be noted that the position of the heat dissipation portion 315 on the inner surface of the housing 3 can be set according to actual conditions.

[0056] According to some embodiments of the present invention, Figure 3 As shown, the heat dissipation portion 315 and the housing 3 can be integrally formed.

[0057] That is to say, the heat dissipation part 315 and the outer shell 3 can be constructed as an integrally formed part with good structural strength. By integrally forming the heat dissipation part 315 and the outer shell 3, the connection reliability between the heat dissipation part 315 and the outer shell 3 can be improved, and the probability of breakage at the connection between the heat dissipation part 315 and the outer shell 3 can be reduced. The integrally formed heat dissipation part 315 and the outer shell 3 can ensure that the connection area between the heat dissipation part 315 and the outer shell 3 is larger, which is beneficial to the heat dissipation of the steering feel simulation device 10.

[0058] It should be noted that the steering feel simulation device 10 of the present application adopts a fully redundant design. The three-phase terminal 11, the three-phase pad 215, the first connector 211, the second connector 221, the power plug terminal 212, the plug hole 314, the sensor 214 and the heat dissipation part 315 of the steering feel simulation device 10 are all provided in multiple. The multiple three-phase terminals 11, the multiple three-phase pads 215, the multiple first connectors 211, the multiple second connectors 221, the multiple power plug terminals 212, the multiple plug holes 314, the multiple sensors 214 and the multiple heat dissipation parts 315 are arranged one by one, thereby forming multiple sets of control groups. When one of the multiple sets of control groups fails, another set of control groups can be used to operate. The present application takes two sets of control groups as an example for explanation. The two sets of control groups are symmetrically arranged, which is conducive to improving the structural consistency of the steering feel simulation device 10 and also conducive to improving the structural stability of the steering feel simulation device 10.

[0059] A vehicle according to an embodiment of the present invention includes the steering feel simulation device 10 of the above embodiment. The stacked arrangement of the power board 21 and the control board 22 is conducive to reducing the volume of the control unit 2 and reducing the space occupied by the control unit 2, thereby helping to reduce the space occupied by the steering feel simulation device 10 in the vehicle and reduce the probability of interference between the steering feel simulation device 10 and other components in the vehicle, and the power board 21 and the control board 22 can be reliably connected through the plug-in cooperation of the first connector 211 and the second connector 221.
