[0028] The present invention provides a turbocharger electronically controlled actuator.

[0029] See also Figures 1 to 3 In one embodiment of the present invention, the turbocharger electronically controlled actuator includes a housing 1 having an accommodating chamber 11 and a motor assembly 2, a control assembly 3, and a transmission assembly 4 disposed in the accommodating chamber 11; the motor assembly 2 includes a motor body 21, a first rotating shaft 22, and an elastic member 23. The first rotating shaft 22 is rotatably disposed on the motor body 21, and the elastic member 23 is disposed on one side of the motor body 21. One end of the first rotating shaft 22 is transmission-connected to the transmission assembly 4, and the other end of the first rotating shaft 22 elastically abuts against the inner wall of the accommodating chamber 11 through the elastic member 23; the control assembly 3 is located on the motor body 2 On a side away from the elastic member 23, the control assembly 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 connecting seat 331 and a plurality of first connecting terminals 332 provided on the connecting seat 331. One end of the first connecting terminal 332 is inserted into the first mounting hole 311 of the first circuit board 31 and is welded and fixed to the first circuit board 31. The other end of the first connecting 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 adopts a first circuit board 31, a second circuit board 32 and a connector 33 which are arranged on the side of the motor body 21 away from the elastic member 23. The other end of the first rotating shaft 22 is elastically abutted 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 from 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 a pin needle. The first circuit board 31 of the present application 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 the signal transmission between the first circuit board 31 and the second circuit board 32.

[0031] In this embodiment, the first direction may coincide with the length of the housing 1, the second direction may coincide with the height of the housing 1, and the first direction may intersect with the second direction. To facilitate the motor assembly 2 driving the transmission assembly 4 to rotate, a first rotating shaft 22 is rotatably disposed on the motor body 21. One end of the first rotating shaft 22 is in transmission connection with the transmission assembly 4. The motor body 21 drives the first rotating shaft 22 to rotate, thereby driving the transmission assembly 4 to rotate. An 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 between the first rotating shaft 22 and the inner wall of the accommodating chamber 11. The elastic properties of the elastic member 23 offset the axial movement of the motor assembly 2 during rotation, further reducing the transmission of vibration generated by the motor assembly 2 during operation to the control assembly 3, and improving the stability of the control assembly 3 installed in the accommodating chamber 11. To improve the stability of the electrical connection between the first circuit board 31 and the second circuit board 32, the present application uses a connector 33 to directly connect the first circuit board 31 and the second circuit board 32, respectively, to provide electrical connection between the first circuit board 31 and the second circuit board 32. Compared to the prior art, where circuit boards are secured and signal transmitted via pins through soldering, the present invention utilizes a connector 33 to directly connect the first and second circuit boards 31 and 32, thereby avoiding issues such as cold solder joints, false solder joints, and leaky solder joints during soldering, and improving the stability of signal transmission between the first and second circuit boards 31 and 32. The connector 33 may include a connection base 331 and a plurality of first connection terminals 332 inserted into the connection base 331. One end of each of the plurality of first connection terminals 332 is inserted into the plurality of first mounting holes 311 of the first circuit board 31 and secured to the first circuit board 31 via 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 ends of each of the plurality of first connection terminals 332 are inserted into the plurality of second mounting holes 321 of the second circuit board 32 and secured to the second circuit board 32 via elastic abutment between the first connection terminals 332 and the walls of the second mounting holes 321, thereby electrically connecting the connector 33 and the second circuit board 32 and improving the stability of the electrical connection between the first and second circuit boards 31 and 32 via the connector 33. In one embodiment, the elastic member 23 may be configured as a wave spring.

[0032] like Figure 3 As shown, in one embodiment, an elastic portion 3321 is provided at one end of the first connecting terminal 332 away from the first circuit board 31, and a second mounting hole 321 is provided on the second circuit board 32. 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 an elastic conductive material, which facilitates electrical conduction between the first connection terminal 332 and the second circuit board 32 through the elastic portion 3321. This application adopts the method of providing an elastic portion 3321 at the end of the first connection terminal 332 facing away from the first circuit board 31. By utilizing the elasticity of the elastic portion 3321, the first connection terminal 332 is snapped onto the second circuit board 32, thereby electrically connecting the first connection terminal 332 to the second circuit board 32. After the first connection terminal 332 is inserted into the second mounting hole 321, the elastic portion 3321 on the first connection terminal 332 elastically resets and elastically abuts against the hole wall of the second mounting hole 321, thereby fixing the first connection terminal 332 to the second circuit board 32, thereby 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 arranged on one side of the transmission assembly 4 along the first direction, and the control assembly 3 is located on the side of the motor assembly 2 away from the elastic member 23 along the second direction, wherein the first direction intersects with the second direction.

[0035] In this embodiment, the first direction may be consistent with the length direction of the housing 1, the second direction may be consistent with the height direction of the housing 1, and 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 in the accommodating cavity 11. By setting the motor assembly 2 and the control assembly 3 to be arranged on one side of the transmission assembly 4 along the first direction, and the control assembly 3 to be arranged on one side of the motor assembly 2 along the second direction, the control assembly 3 is located on the side away from the elastic member 23 and the transmission assembly 4, so as to reduce the impact of the vibration generated by the transmission assembly 4 and the motor assembly 2 during operation on the control assembly 3, and further improve the stability of the 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 arranged 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 provided in the stator 211, and the first rotating shaft 22 is rotatably provided on the rotor 212.

[0037] In this embodiment, the elastic member 23 is positioned below the stator 211, the control assembly 3 is positioned above the stator 211, and the rotor 212 and stator 211 are positioned to one side of the transmission assembly 4 along the first direction. This allows the control assembly 3 to be positioned away from both the elastic member 23 and the transmission assembly 4, thereby preventing vibration generated by the motor assembly 2 from separating the first circuit board 31 and the second circuit board 32. To ensure that the motor assembly 2 more stably drives the transmission assembly 4 to rotate, the second circuit board 32 supplies power to the stator 211, generating a rotating magnetic field. This rotating magnetic field causes the rotor 212 to rotate, thereby driving the first shaft 22 and the transmission assembly 4 to rotate.

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

[0039] In this embodiment, to improve the stability of the connection between the stator 211 and the second connection terminals 2112, a plurality of first connection posts 2111 may be protruding from the side of the stator 211 near the second circuit board 32. The plurality of first connection posts 2111 are arranged along the circumference of the stator 211, and each first connection post 2111 is provided with a second connection terminal 2112 on the side near the second circuit board 32. To improve the stability of the electrical connection 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 connection terminals 2112 are inserted into the plurality of third mounting holes 322 in a one-to-one manner. The second connection terminals 2112 are fixed to the third mounting holes 322 by welding, thereby securing the stator 211 to the second circuit board 32. In one embodiment, the number of the first connecting columns 2111 can be three, and the number of the third mounting holes 322 can be correspondingly three, so that there are only three welding points in the stator 211 after the pre-buried wire treatment, thereby avoiding problems such as cold welding, false welding and leaking 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 electronically controlled actuator further includes a detection component 5, and the motor body 21 further includes a magnetic ring component 213. The magnetic ring component 213 is provided at one end of the first rotating shaft 22 close to the elastic component 23. The detection component 5 is electrically connected to the first circuit board 31 and the second circuit board 32. The detection component 5 is provided on the side of the second circuit board 32 away from the first circuit board 31. The detection component 5 is located below the magnetic ring component 213. The detection component 5 is used to detect the operating parameters of the magnetic ring component 213 and form a first signal, so that the second circuit board 32 can transmit the first signal to the first circuit board 31 through the first connecting terminal 332.

[0041] In this embodiment, the rotor 212 includes a transmission member (not shown), a first bearing (not shown), a magnetic ring member 213, a permanent magnet member (not shown) and a second bearing (not shown) sequentially arranged on the first rotating shaft 22 along the axial direction of the first rotating shaft 22. The transmission member is arranged at one end of the first rotating shaft 22 away from the elastic member 23, and the magnetic ring member 213 can be arranged at one end of the first rotating shaft 22 close to the elastic member 23. The magnetic ring member 213 can rotate with the rotation of the stator 211 and the rotor 212, so that the magnetic ring member 213 can provide real-time feedback on the operating parameters of the motor body 21, which may include real-time operating parameters such as speed and torque. In order to make it more convenient for the detection member 5 to detect the operating parameters of the magnetic ring member 213 in real time, the detection member 5 can be located directly below the magnetic ring member 213. The detection member 5 detects and records the operating parameters of the magnetic ring member 213 during the rotation process to form a first signal. The second circuit board 32 transmits the first signal to the first circuit board 31 through the first connecting terminal 332. The first circuit board 31 matches the first signal with the preset operating parameters, thereby adjusting the operating parameters such as the rotational speed and torque of the motor body 21 in real time. In one embodiment, in order to more conveniently detect the operating parameters of the magnetic ring member 213, the detection member 5 can be set to multiple, and the multiple detection members 5 are arranged along the circumference of the second circuit board 32. In one embodiment, in order to improve the accuracy of the detection member 5 in detecting the magnetic ring member 213, the detection member 5 can use a sensor such as a Hall sensor or a magnetoresistive sensor. In one embodiment, the first bearing and the second bearing can use deep groove ball bearings.

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

[0043] In this embodiment, the connector 6 can be installed on the inner wall of the accommodating cavity 11 by means of a fastener. The connector 6 has a first mounting groove 61. The end of the first rotating shaft 22 facing away from the elastic member 23 is passed through the first mounting groove 61. The first bearing is installed in the first mounting groove 61, thereby improving the stability of the first rotating shaft 22 and the first bearing when installed in the accommodating cavity 11. The transmission member on the first rotating shaft 22 can be located on the side of the connector 6 facing away from the second circuit board 32, thereby facilitating the transmission connection between the transmission member and the transmission assembly 4. The present application facilitates the installation of the first bearing and the positioning of the motor assembly 2 by arranging the connector 6 between the first circuit board 31 and the second circuit board 32. In one embodiment, the fastener can be configured as a fastener such as a bolt, a screw, or a latch.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the housing 1 includes a first shell 12 and a second shell 13 connected to each other, and the accommodating cavity 11 is enclosed between the first shell 12 and the second shell 13.

The second mounting groove 121 and the sixth mounting hole 122 are both connected to the accommodating cavity 11, the motor assembly 2 is arranged in the second mounting groove 121, and the transmission assembly 4 is arranged in the sixth mounting hole 122.

[0045] In this embodiment, the second housing 13 is removably attached to the first housing 12, so that a housing cavity 11 is enclosed between the first and second housings 12, 13. To more rationally plan the specific positions of the transmission assembly 4, the control assembly 3, and the motor assembly 2, the first housing 12 has a second mounting groove 121 and a sixth mounting hole 122 spaced apart along the 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 to one side of the transmission assembly 4 along the first direction, which can reduce the impact of vibration 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 shell 12 has a first mounting portion 124, the connecting member 6 has a fourth mounting hole 62, and the second circuit board 32 has a fifth mounting hole 323 that matches 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 that the connecting member 6, the second circuit board 32 and the first shell 12 are connected and fixed.

[0047] In this embodiment, the present application utilizes fixing pins 7, which are respectively inserted through the fourth mounting hole 62, the fifth mounting hole 323, and the first mounting portion 124, to facilitate the installation and positioning of the second circuit board 32 and improve the stability of the second circuit board 32 and the connector 6 when mounted on the first housing 12. The inner sidewall of the first housing 12 may also be provided with a second mounting portion 125. The connector may be 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 to the second mounting portion 125 of the first housing 12 via fasteners. This facilitates the positioning and installation of the rotor 212 and the transmission components on the rotor 212 within the first housing 12, ensuring the center distance between the rotor 212 and the transmission components, and thereby ensuring the coaxiality of the subsequently installed stator 211 and rotor 212. This improves the operating efficiency of the motor body 21 and reduces the noise generated during operation of the motor body 21. In one embodiment, the fasteners may be bolts, screws, or latches.

[0048] like Figure 5 As shown, in one embodiment, the first shell 12 has a third mounting groove 123 connected to the second mounting groove 121, and the inner wall of the third mounting groove 123 is provided with a plurality of mounting columns 1231, and the plurality of mounting columns 1231 are arranged at intervals along the circumference of the third mounting groove 123, and the mounting columns 1231 are used for the installation of the stator 211, and a clamping groove 1232 connected to the third mounting groove 123 is formed between two adjacent mounting columns 1231, and the outer peripheral wall of the stator 211 is provided with a clamping portion 2113, and the clamping portion 2113 is clamped in the clamping groove 1232.
