Currently, the three-phase DC motor widely used in turbocharger actuators is a brushless motor, which has the advantages of fewer internal mechanical parts and a relatively simple structure. The commutation of brushless motors is achieved through electronic control; these electronically controlled brushless motors mainly consist of a stator, rotor, and circuit board. However, existing turbocharger electronic control actuators suffer from poor signal transmission stability and complex internal circuit structures, failing to meet user requirements.

[0005] In one embodiment, the end of the first connecting terminal away from the first circuit board is provided with an elastic portion, and the second circuit board is provided with a second mounting hole. The first connecting terminal is inserted into the second mounting hole so that the elastic portion elastically abuts against the wall of the second mounting hole.

[0006] In one embodiment, the motor assembly and the control assembly are disposed on one side of the transmission assembly along a first direction, and the control assembly is located on the side of the motor assembly away from the elastic member along a second direction, wherein the first direction intersects the second direction.

[0008] In one embodiment, a first connecting post protrudes from the side of the stator away from the elastic member, and a second connecting terminal is provided on the side of the first connecting post near the second circuit board. The second circuit board has a third mounting hole, and the second connecting terminal is inserted into the third mounting hole and welded to the second circuit board.

[0009] In one embodiment, the turbocharger electronic control actuator further includes a detection element, and the motor body further includes a magnetic ring element. The magnetic ring element is disposed at one end of the first rotating shaft near the elastic element. The detection element is electrically connected to the first circuit board and the second circuit board. The detection element is disposed on the side of the second circuit board away from the first circuit board. The detection element is located below the magnetic ring element. The detection element is used to detect the operating parameters of the magnetic ring element and generate a first signal, so that the second circuit board can transmit the first signal to the first circuit board through the first connection terminal.

[0010] In one embodiment, the turbocharger electronic control actuator further includes a connector disposed in the receiving cavity, the connector being located between the first circuit board and the second circuit board, the connector having a first mounting groove, and the end of the first rotating shaft opposite to the elastic member passing through the first mounting groove, so that the transmission member on the first rotating shaft is located on the side of the connector opposite to the second circuit board.

[0011] In one embodiment, the housing includes a first outer shell and a second outer shell connected to each other, and the accommodating cavity is formed between the first outer shell and the second outer shell.

[0028] This invention proposes a turbocharger electronic control actuator.

[0029] Please see Figures 1 to 3 In one embodiment of the present invention, the turbocharger electronically controlled actuator includes a housing 1, having a receiving cavity 11 and a motor assembly 2, a control assembly 3, and a transmission assembly 4 disposed within the receiving cavity 11; the motor assembly 2 includes a motor body 21, a first rotating shaft 22, and an elastic element 23, the first rotating shaft 22 being rotatably disposed on the motor body 21, the elastic element 23 being disposed on one side of the motor body 21, one end of the first rotating shaft 22 being drively connected to the transmission assembly 4, and the other end of the first rotating shaft 22 being elastically abutting against the inner wall of the receiving cavity 11 through the elastic element 23; the control assembly 3 is located within the motor body 21. On the side away from the elastic element 23, the control component 3 includes a first circuit board 31, a second circuit board 32, and a connector 33. The second circuit board 32 is electrically connected to the motor body 21. The connector 33 includes a connector base 331 and a plurality of first connector terminals 332 disposed on the connector base 331. One end of the first connector terminal 332 is inserted into the first mounting hole 311 of the first circuit board 31 and is soldered and fixed to the first circuit board 31. The other end of the first connector terminal 332 is inserted into the second mounting hole 321 of the second circuit board 32 and elastically abuts against the hole wall of the second mounting hole 321.

[0030] The technical solution of the present invention employs a first circuit board 31, a second circuit board 32, and a connector 33 disposed on the side of the motor body 21 away from the elastic member 23. The other end of the first rotating shaft 22 elastically abuts against the inner wall of the accommodating cavity 11 through the elastic member 23, so that the elastic member 23 can offset the vibration generated by the motor assembly 2 during operation, thereby preventing the connector 33 from falling off the first circuit board 31 or the second circuit board 32 under the action of vibration, thereby improving the signal transmission stability of the control assembly 3. Compared with the prior art, the signal transmission between the first circuit board 31 and the second circuit board 32 is electrically connected through pins. In this application, the first circuit board 31 is directly electrically connected to the second circuit board 32 through the first connecting terminal 332, which simplifies the connection method of the first circuit board 31 and the second circuit board 32 and improves the stability of signal transmission between the first circuit board 31 and the second circuit board 32.

[0031] In this embodiment, the first direction may be consistent with the length direction of the housing 1, and the second direction may be consistent with the height direction of the housing 1. The first direction may intersect with the second direction. To facilitate the rotation of the transmission assembly 4 driven by the motor assembly 2, the first rotating shaft 22 is rotatably disposed on the motor body 21. One end of the first rotating shaft 22 is connected to the transmission assembly 4. The motor body 21 drives the first rotating shaft 22 to rotate, thereby driving the transmission assembly 4 to rotate. The elastic member 23 is disposed on one side of the motor body 21 along the second direction. The two ends of the elastic member 23 elastically abut against the first rotating shaft 22 and the inner wall of the accommodating cavity 11, respectively. This application uses the elastic properties of the elastic member 23 to counteract the axial movement of the motor assembly 2 during rotation, further reducing the vibration generated by the motor assembly 2 during operation and transmitting it to the control assembly 3, thereby improving the stability of the control assembly 3 installed in the accommodating cavity 11. To improve the stability of the electrical connection between the first circuit board 31 and the second circuit board 32, this application uses a connector 33 to directly connect the first circuit board 31 and the second circuit board 32, respectively, for electrical connection between the first circuit board 31 and the second circuit board 32. Compared to existing technologies that use pins to fix circuit boards and transmit signals, this application uses a connector 33 to directly connect the first circuit board 31 and the second circuit board 32. This avoids problems such as cold solder joints, false solder joints, and missing solder joints during pin soldering, thus improving the stability of signal transmission between the first circuit board 31 and the second circuit board 32. The connector 33 may include a connector base 331 and multiple first connection terminals 332 inserted into the connector base 331. One end of each of the multiple first connection terminals 332 is inserted one-to-one into multiple first mounting holes 311 of the first circuit board 31 and fixed to the first circuit board 31 by soldering, thereby electrically connecting the connector 33 and the first circuit board 31 and improving the stability of the connection between the connector 33 and the first circuit board 31. The other end of each of the multiple first connection terminals 332 is inserted one-to-one into multiple second mounting holes 321 of the second circuit board 32 and fixed to the second circuit board 32 by elastic abutment between the first connection terminal 332 and the wall of the second mounting hole 321, thereby electrically connecting the connector 33 and the second circuit board 32 and improving the stability of the electrical connection between the first circuit board 31 and the second circuit board 32 via the connector 33. In one embodiment, the elastic element 23 may be configured as a wave spring.

[0032] like Figure 3 As shown, in one embodiment, the first connecting terminal 332 has an elastic portion 3321 at one end away from the first circuit board 31, and the second circuit board 32 has a second mounting hole 321. The first connecting terminal 332 is inserted into the second mounting hole 321 so that the elastic portion 3321 elastically abuts against the hole wall of the second mounting hole 321.

[0033] In this embodiment, the elastic portion 3321 can be made of a conductive material with elasticity, facilitating electrical connection between the first connecting terminal 332 and the second circuit board 32 through the elastic portion 3321. This application utilizes the elastic portion 3321 at the end of the first connecting terminal 332 facing away from the first circuit board 31. By leveraging the elasticity of the elastic portion 3321, the first connecting terminal 332 is snapped onto the second circuit board 32, thereby achieving electrical connection between the first connecting terminal 332 and the second circuit board 32. After the first connecting terminal 332 is inserted into the second mounting hole 321, the elastic portion 3321 on the first connecting terminal 332 elastically resets and elastically abuts against the wall of the second mounting hole 321, thus fixing the first connecting terminal 332 onto the second circuit board 32 and improving the stability of the connection between the connector 33 and the second circuit board 32.

[0034] like Figure 2 and Figure 4 As shown, in one embodiment, the motor assembly 2 and the control assembly 3 are disposed on one side of the transmission assembly 4 along a first direction, and the control assembly 3 is located on the side of the motor assembly 2 away from the elastic member 23 along a second direction, wherein the first direction intersects the second direction.

[0035] In this embodiment, the first direction may be consistent with the length direction of the housing 1, and the second direction may be consistent with the height direction of the housing 1. The first direction may intersect with the second direction. This application plans the installation positions of the motor assembly 2, the control assembly 3, and the transmission assembly 4 within the accommodating cavity 11. By setting the motor assembly 2 and the control assembly 3 to be located on one side of the transmission assembly 4 along the first direction, and the control assembly 3 to be located on one side of the motor assembly 2 along the second direction, and the control assembly 3 to be located away from the elastic member 23 and the transmission assembly 4, the impact of vibrations generated by the transmission assembly 4 and the motor assembly 2 during operation on the control assembly 3 is reduced, further improving the stability of signal transmission between the first circuit board 31, the second circuit board 32, and the motor assembly 2.

[0036] like Figure 2 and Figure 4 As shown, in one embodiment, the motor body 21 includes a stator 211 and a rotor 212. The control component 3 is disposed above the stator 211. The stator 211 is located on one side of the transmission component 4 along the first direction. The stator 211 is electrically connected to the second circuit board 32. The rotor 212 is rotatably disposed within the stator 211. The first rotating shaft 22 is rotatably disposed on the rotor 212.

[0037] In this embodiment, the elastic element 23 is located below the stator 211, and the control component 3 is located above the stator 211. The rotor 212 and the stator 211 are located on one side of the transmission component 4 along the first direction, so that the control component 3 is simultaneously away from the elastic element 23 and the transmission component 4, preventing the vibration generated by the motor component 2 from causing the first circuit board 31 and the second circuit board 32 to separate. In order to make the motor component 2 drive the transmission component 4 to rotate more stably, the second circuit board 32 energizes the stator 211, so that the stator 211 generates a rotating magnetic field after being energized. The rotor 212 rotates under the action of the rotating magnetic field, thereby driving the first rotating shaft 22 and the transmission component 4 to rotate.

[0038] like Figure 5 and Figure 6 As shown, in one embodiment, the stator 211 has a first connecting post 2111 protruding on the side away from the elastic member 23. The first connecting post 2111 has a second connecting terminal 2112 on the side near the second circuit board 32. The second circuit board 32 has a third mounting hole 322. The second connecting terminal 2112 is inserted into the third mounting hole 322 and welded to the second circuit board 32.

[0039] In this embodiment, to improve the stability of the connection between the stator 211 and the second connecting terminal 2112, a plurality of first connecting posts 2111 may be protruding on the side of the stator 211 near the second circuit board 32. The plurality of first connecting posts 2111 are arranged circumferentially along the stator 211, and each first connecting post 2111 has a second connecting terminal 2112 on the side near the second circuit board 32. To improve the stability of the conduction between the stator 211 and the second circuit board 32, the second circuit board 32 may have a plurality of third mounting holes 322. The plurality of second connecting terminals 2112 are inserted one-to-one into the plurality of third mounting holes 322, and the second connecting terminals 2112 are fixed in the third mounting holes 322 by welding, so that the stator 211 and the second circuit board 32 are welded and fixed. In one embodiment, the first connecting post 2111 can be set to three, and the third mounting hole 322 can be set to three correspondingly, so that there are only three welding points after the stator 211 is pre-embedded, avoiding problems such as false welding, cold welding and missing welding when welding the stator 211 and the second circuit board 32, and simplifying the welding time of the stator 211 and the second circuit board 32.

[0040] like Figure 3As shown, in one embodiment, the turbocharger electronic control actuator further includes a detection element 5, and the motor body 21 further includes a magnetic ring element 213. The magnetic ring element 213 is disposed at one end of the first rotating shaft 22 near the elastic element 23. The detection element 5 is electrically connected to the first circuit board 31 and the second circuit board 32. The detection element 5 is disposed on the side of the second circuit board 32 opposite to the first circuit board 31. The detection element 5 is located below the magnetic ring element 213. The detection element 5 is used to detect the operating parameters of the magnetic ring element 213 and generate a first signal, so that the second circuit board 32 can transmit the first signal to the first circuit board 31 through the first connection terminal 332.

[0041] In this embodiment, the rotor 212 includes a transmission component (not shown), a first bearing (not shown), a magnetic ring component 213, a permanent magnet component (not shown), and a second bearing (not shown) sequentially arranged along the axial direction of the first rotating shaft 22. The transmission component is located at the end of the first rotating shaft 22 away from the elastic member 23, and the magnetic ring component 213 can be located at the end of the first rotating shaft 22 closer to the elastic member 23. The magnetic ring component 213 can rotate with the rotation of the stator 211 and the rotor 212, so that the magnetic ring component 213 can provide real-time feedback on the operating parameters of the motor body 21. The operating parameters may include real-time operating parameters such as speed and torque. To facilitate the real-time detection of the operating parameters of the magnetic ring component 213 by the detection component 5, the detection component 5 can be located directly below the magnetic ring component 213. The detection element 5 detects and records the operating parameters of the magnetic ring 213 during rotation to form a first signal. The second circuit board 32 transmits the first signal to the first circuit board 31 through the first connection terminal 332. The first circuit board 31 matches the first signal with preset operating parameters and then adjusts the operating parameters such as the speed and torque of the motor body 21 in real time. In one embodiment, to facilitate the detection of the operating parameters of the magnetic ring 213, multiple detection elements 5 can be set, and the multiple detection elements 5 are arranged circumferentially along the second circuit board 32. In one embodiment, to improve the accuracy of the detection element 5 in detecting the magnetic ring 213, the detection element 5 can be a Hall sensor or a magnetoresistive sensor. In one embodiment, the first bearing and the second bearing can be deep groove ball bearings.

[0042] like Figure 3 As shown, in one embodiment, the turbocharger electronic control actuator further includes a connector 6, which is disposed in the receiving cavity 11 and located between the first circuit board 31 and the second circuit board 32. The connector 6 has a first mounting groove 61, and one end of the first rotating shaft 22 away from the elastic member 23 passes through the first mounting groove 61 so that the transmission member on the first rotating shaft 22 is located on the side of the connector 6 away from the second circuit board 32.

[0043] In this embodiment, the connector 6 can be mounted on the inner wall of the accommodating cavity 11 using fasteners. The connector 6 has a first mounting groove 61. The end of the first rotating shaft 22 facing away from the elastic member 23 passes through the first mounting groove 61, and the first bearing is mounted in the first mounting groove 61, improving the stability of the first rotating shaft 22 and the first bearing within the accommodating cavity 11. The transmission component on the first rotating shaft 22 can be located on the side of the connector 6 facing away from the second circuit board 32, facilitating the transmission connection between the transmission component and the transmission assembly 4. This application facilitates the installation of the first bearing and the positioning of the motor assembly 2 by placing the connector 6 between the first circuit board 31 and the second circuit board 32. In one embodiment, the fastener can be a bolt, screw, or pin, etc.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the housing 1 includes a first outer shell 12 and a second outer shell 13 connected to each other. The first outer shell 12 and the second outer shell 13 enclose the receiving cavity 11. The first outer shell 12 has a second mounting groove 121 and a sixth mounting hole 122 spaced apart along the first direction. The second mounting groove 121 and the sixth mounting hole 122 are both in communication with the receiving cavity 11. The motor assembly 2 is disposed in the second mounting groove 121, and the transmission assembly 4 is disposed in the sixth mounting hole 122.

[0045] In this embodiment, the second outer shell 13 is detachably fitted onto the first outer shell 12, so that a receiving cavity 11 is formed between the first outer shell 12 and the second outer shell 13. To more rationally plan the specific positions of the transmission assembly 4, the control assembly 3, and the motor assembly 2, the first outer shell 12 has a second mounting groove 121 and a sixth mounting hole 122 spaced apart along a first direction. The motor assembly 2 is disposed within the second mounting groove 121, and the transmission assembly 4 is mounted in the sixth mounting hole 122. The motor assembly 2 is located on one side of the transmission assembly 4 along the first direction, which can reduce the impact of vibrations generated by the transmission assembly 4 and the motor assembly 2 during operation on the control assembly 3, further improving the stability of signal transmission between the first circuit board 31, the second circuit board 32, and the motor assembly 2.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment, the inner wall of the first housing 12 has a first mounting portion 124, the connector 6 has a fourth mounting hole 62, and the second circuit board 32 has a fifth mounting hole 323 that mates with the fourth mounting hole 62. The fourth mounting hole 62, the fifth mounting hole 323, and the first mounting portion 124 are respectively connected and fixed by fixing pins 7 so as to connect and fix the connector 6, the second circuit board 32, and the first housing 12.

[0047] In this embodiment, the present application employs fixing pins 7 respectively inserted into the fourth mounting hole 62, the fifth mounting hole 323, and the first mounting portion 124, to mount the second circuit board 32 and the connector 6 onto the first housing 12. This facilitates the installation and positioning of the second circuit board 32 and improves the stability of the second circuit board 32 and the connector 6 mounted on the first housing 12. The inner sidewall of the first housing 12 may also be provided with a second mounting portion 125, and the connector is provided with a third mounting portion 63 corresponding to the second mounting portion 125. The third mounting portion 63 on the connector 6 is mounted on the second mounting portion 125 of the first housing 12 by fasteners, making it easier to position and install the rotor 212 and the transmission components on the rotor 212 within the first housing 12. This ensures the center distance between the rotor 212 and the transmission components, thereby ensuring the coaxiality of the subsequently installed stator 211 and rotor 212, thereby improving the operating efficiency of the motor body 21 and reducing the noise generated by the motor body 21 during operation. In one embodiment, the fasteners may be bolts, screws, or pins.

[0048] like Figure 5 As shown, in one embodiment, the first housing 12 has a third mounting groove 123 communicating with the second mounting groove 121. The inner wall of the third mounting groove 123 is provided with a plurality of mounting posts 1231, which are spaced apart circumferentially along the third mounting groove 123. The mounting posts 1231 are used for mounting the stator 211. A snap-fit ​​groove 1232 communicating with the third mounting groove 123 is formed between two adjacent mounting posts 1231. The outer peripheral wall of the stator 211 is provided with a snap-fit ​​portion 2113, which snaps into the snap-fit ​​groove 1232.

[0049] In this embodiment, to improve the stability of the connection between the motor assembly 2 and the housing 1, the first housing 12 may have a third mounting groove 123 communicating with the second mounting groove 121, and the stator 211 and the rotor 212 may be installed in the third mounting groove 123.
