Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to an opening adjustment actuator, a compressor, and a vehicle. Background Technology

[0002] The compressor is the intake compression unit of the turbocharger. The turbocharger also includes a turbine that is rigidly connected to the compressor coaxially via an intermediate body. The compressor is connected to the engine's intake manifold, and the turbine is connected to the engine's exhaust manifold. Outside air enters the compressor through the air filter, is compressed in the compressor, and then enters the engine's intake manifold through the intercooler. After entering the engine cylinders to participate in combustion, it enters the turbine through the exhaust manifold, directly impacting the turbine impeller to drive it to rotate at high speed. When the turbine impeller rotates, it can directly transfer mechanical energy to the compressor impeller, driving it to rotate synchronously and compress the air during rotation.

[0003] In particular, when the engine operates at low speed and high torque in a high-altitude environment with low atmospheric pressure (such as when a vehicle is heavily loaded and climbing a hill, or when it accelerates rapidly from a standstill), the compressor's operating point will be very close to the surge boundary, which can easily cause compressor surge, and there is room for improvement. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an opening adjustment actuator, which can reduce the compressor's inlet diameter by reducing the opening of the inlet, thereby reducing the compressor's trim and shifting the surge boundary towards the direction of lower flow rate. This allows the operating point to fall to the right of the surge boundary, reducing the likelihood of surge occurring.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following is for reference. Figures 1-18 According to an embodiment of the present invention, the opening adjustment actuator 100 can reduce the intake diameter of the compressor 200 by reducing the opening of the intake port 202, thereby reducing the trim of the compressor 200, causing the surge boundary to move towards the direction of low flow, so that the operating point can fall to the right of the surge boundary, reducing the possibility of surge phenomenon.

[0026] like Figures 1-17As shown, according to an embodiment of the present invention, the opening adjustment actuator 100 is adapted to be connected to the compressor 200, and the compressor 200 is provided with an air inlet 202. The opening adjustment actuator 100 includes a drive structure and an adjustment structure 2.

[0027] The adjustment structure 2 includes an adjustment ring 21 and multiple adjustment blades 22. The drive structure is connected to the adjustment ring 21 to drive the adjustment ring 21 to rotate. The adjustment blades 22 are rotatable, and the multiple adjustment blades 22 are distributed around the air inlet 202. One of the adjustment ring 21 and the adjustment blades 22 is provided with a guide protrusion 221 and the other is provided with a guide groove 211. The guide protrusion 221 is located in the guide groove 211 and can slide along the guide groove 211. The adjustment ring 21 is configured to rotate by sliding cooperation between the guide protrusion 221 and the guide groove 211 to make the multiple adjustment blades 22 rotate together and adjust the opening of the air inlet 202.

[0028] Specifically, the compressor 200 is the intake compression unit of the turbocharger. Its core function is to compress the air entering the engine, increasing its pressure and density. The compressor 200 is equipped with an air inlet 202, which is connected to the external environment, allowing outside air to enter the compressor 200. The compressor 200 then performs work on the air through its rotating impeller, converting mechanical energy into the internal energy of the air, thus significantly increasing the air pressure. The opening adjustment actuator 100 is used to adjust the intake diameter of the compressor 200. Connecting the opening adjustment actuator 100 to the compressor 200 means connecting the opening adjustment actuator 100 to the air inlet 202 of the compressor 200. The opening adjustment actuator 100 can change the intake diameter of the compressor 200 by adjusting the opening size of the air inlet 202, thereby increasing or decreasing the intake diameter of the compressor 200.

[0029] It should be noted that, as Figure 18 As shown, the surge boundary is the critical line on the compressor 200 map that distinguishes the stable operating region from the unstable operating region. It is formed by connecting the surge points at different speeds. When the engine operates at low speed and high torque in a high-altitude environment with low atmospheric pressure (such as when a vehicle is heavily loaded and climbing a hill, or when it accelerates rapidly from a standstill), the operating point of the compressor 200 will be very close to the surge boundary, which can easily cause the compressor 200 to surge. To improve the engine's high-altitude performance, the most direct way is to reduce the trim of the compressor 200. Reducing the trim of the compressor 200 can widen the surge boundary, causing it to move towards the direction of low flow, so that the operating point can fall to the right of the surge boundary, thus reducing the possibility of surge.

[0030] Furthermore, the trim of compressor 200 = (inlet diameter) 2 / exhaust diameter 2The relative diameter of the inlet (the ratio of the inlet diameter to the outlet diameter) has a significant negative impact on the surge boundary range. Reducing the inlet diameter can shift the surge boundary towards a lower flow rate, expand the stable operating range, and reduce the likelihood of surge. Thus, the opening of the inlet 202 can be reduced by adjusting the opening of the actuator 100 to reduce the inlet diameter of the compressor 200, thereby reducing the likelihood of surge.

[0031] The opening adjustment actuator 100 includes a drive structure and an adjustment structure 2. The adjustment structure 2 is used to adjust the opening of the air inlet 202, and the drive structure is used to provide driving force. The drive structure is connected to the adjustment structure 2 so that the drive structure can transmit the driving force to the adjustment structure 2. That is, the drive structure can drive the adjustment structure 2 to move to change the opening of the air inlet 202. Moreover, the adjustment structure 2 includes an adjustment ring 21 and multiple adjustment blades 22. The drive structure is connected to the adjustment ring 21 so that the adjustment structure 2 and the drive structure can be connected through the adjustment ring 21. That is, the drive structure can transmit the driving force to the adjustment ring 21 so that the drive structure can drive the adjustment ring 21 to rotate. There are multiple adjustment blades 22. That is, the number of adjustment blades 22 can be two, three or more. The multiple adjustment blades 22 are distributed around the air inlet 202 so that the multiple adjustment blades 22 are distributed sequentially along the circumference of the air inlet 202.

[0032] Furthermore, by setting the adjusting blade 22 to be rotatable, the adjusting ring 21 can be connected to the adjusting blade 22, so that the adjusting ring 21 can drive the adjusting blade 22 to rotate in a direction away from or close to the axis of the air inlet 202, so as to selectively block the air inlet 202, thereby changing the opening size of the air inlet 202.

[0033] Furthermore, one of the adjusting ring 21 and the adjusting blade 22 is provided with a guide protrusion 221 and the other is provided with a guide groove 211. The guide protrusion 221 can be provided on the adjusting ring 21 and the guide groove 211 on the adjusting blade 22, or the guide groove 211 can be provided on the adjusting ring 21 and the guide protrusion 221 on the adjusting blade 22. The guide protrusion 221 is placed within the guide groove 211, so that the adjusting ring 21 and the adjusting blade 22 are connected through the guide protrusion 221 and the guide groove 211. The guide protrusion 221 can slide along the guide groove 211, meaning the guide protrusion 221 and the guide groove 211 are slidably engaged. The guide protrusion 221 can move along the extension direction of the guide groove 211, and the guide groove 211 can guide the movement of the guide protrusion 221.

[0034] Furthermore, the adjusting ring 21 is configured to rotate by means of the guide protrusion 221 and the guide groove 211, so that multiple adjusting blades 22 rotate together and adjust the opening of the air inlet 202. Multiple adjusting blades 22 can be connected to the adjusting ring 21 through multiple sets of guide protrusions 221 and guide grooves 211, so that the adjusting ring 21 can simultaneously drive multiple adjusting blades 22 to rotate in a direction away from or close to the axis of the air inlet 202, thereby adjusting the opening of the air inlet 202.

[0035] It should be noted that the diameter of the air inlet 202 can be adjusted by changing the opening size of the air inlet 202. In this way, the air intake diameter of the compressor 200 can be reduced by decreasing the opening size of the air inlet 202, thereby reducing the trim of the compressor 200 and moving the surge boundary towards the direction of low flow. This allows the operating point to fall to the right of the surge boundary, reducing the possibility of surge and improving the high-altitude performance of the engine. Furthermore, by increasing or decreasing the air intake diameter of the compressor 200 through the opening adjustment actuator 100, the compressor 200 can adapt to different operating conditions, increasing the applicability of the compressor 200.

[0036] According to an embodiment of the present invention, the opening adjustment actuator 100 is connected to the air inlet 202 of the compressor 200, so that the opening adjustment actuator 100 can adjust the opening size of the air inlet 202. The adjustment ring 21 is connected to the drive structure and multiple adjustment blades 22 respectively, so that the adjustment ring 21 can drive the multiple adjustment blades 22 to rotate simultaneously under the action of the drive structure to change the opening size of the air inlet 202. In this way, the air inlet diameter of the compressor 200 can be reduced by reducing the opening size of the air inlet 202, thereby reducing the trim of the compressor 200, causing the surge boundary to move towards the direction of low flow, so that the operating point can fall to the right of the surge boundary, reducing the possibility of surge phenomenon.

[0037] In some embodiments, a plurality of adjusting blades 22 are all arranged to be distributed along the axial direction of the adjusting ring 21; wherein, a guide groove 211 is provided on the side of the adjusting ring 21 facing the adjusting blades 22, and a guide protrusion 221 is provided on the side of the adjusting blades 22 facing the adjusting ring 21.

[0038] In such Figure 11 , Figure 12 , Figures 14-17In the embodiment shown, the adjusting ring 21 is provided with a guide groove 211, and the adjusting blade 22 is provided with a guide protrusion 221. There are six adjusting blades 22, and a guide protrusion 221 is provided on each of the six adjusting blades 22. The adjusting ring 21 is also provided with six guide grooves 211. The six guide grooves 211 are spaced apart and distributed sequentially along the circumference of the adjusting ring 21. Thus, the six guide grooves 211 and the six guide protrusions 221 can correspond one-to-one, so that the adjusting ring 21 can be connected to the six adjusting blades 22 at the same time. Under the action of the driving structure, the six adjusting blades 22 can be driven to rotate in the direction of increasing or decreasing the intake diameter.

[0039] It should be noted that the number of adjusting blades 22, guide protrusions 221 and guide grooves 211 is not limited to that described in this embodiment, and can be flexibly set according to specific needs and space.

[0040] Specifically, multiple adjusting blades 22 are distributed sequentially along the circumference of the air inlet 202, meaning that the multiple adjusting blades 22 are set at the same height. By setting the multiple adjusting blades 22 to be distributed along the axial direction of the adjusting ring 21, the adjusting ring 21 can be constructed into a circular shape. By setting the multiple adjusting blades 22 on the same side of the adjusting ring 21, the guide groove 211 can be set on the side of the adjusting ring 21 facing the adjusting blades 22, and the guide protrusion 221 can be set on the side of the adjusting blades 22 facing the adjusting ring 21, so that the guide groove 211 and the guide protrusion 221 can be close to each other, and thus it is convenient to extend the guide protrusion 221 into the guide groove 211. When the adjusting ring 21 rotates, it can drive the adjusting blades 22 to rotate through the guide groove 211 and the guide protrusion 221 to adjust the opening of the air inlet 202.

[0041] Specifically, the guide groove 211 can have a certain depth along the axial direction of the adjusting ring 21, and the guide protrusion 221 can have a certain length along the axial direction of the adjusting ring 21, so that at least a portion of the guide protrusion 221 can extend into the guide groove 211, thereby connecting the adjusting ring 21 and the adjusting blade 22. This also increases the contact length between the guide groove 211 and the guide protrusion 221, ensuring that the guide groove 211 can push the guide protrusion 221 to move. Figure 11 , Figure 12 , Figure 14 and Figure 15 As shown, the guide groove 211 can also be constructed as a through hole, so that the depth of the guide groove 211 is equal to the thickness of the adjusting ring 21, which can reduce the processing difficulty.

[0042] In some embodiments, the guide groove 211 is configured to extend circumferentially along the adjusting ring 21 and be radially inclined, and the extension directions of the guide grooves 211 corresponding to the plurality of adjusting blades 22 are the same; wherein, when the adjusting ring 21 rotates in the first direction, the plurality of guide grooves 211 jointly drive the corresponding adjusting blades 22 to rotate in the direction of decreasing opening, and when rotating in the second direction, the plurality of guide grooves 211 jointly drive the corresponding adjusting blades 22 to rotate in the direction of increasing opening, and the first direction and the second direction are opposite.

[0043] Specifically, such as Figures 10-15 As shown, the guide groove 211 is used to push the guide protrusion 221 to drive the adjusting blade 22 to rotate when the adjusting ring 21 rotates. The guide groove 211 is constructed to extend circumferentially along the adjusting ring 21, thus giving it a certain length along the circumference of the adjusting ring 21. This allows the guide groove 211 to push the guide protrusion 221 to move along the extension path of the guide groove 211 within its interior, thereby enabling the adjusting ring 21 to drive the adjusting blade 22 to move. Furthermore, the guide groove 211 is constructed to extend circumferentially along the adjusting ring 21. By tilting the guide groove 211, a certain length can be achieved along the radial direction of the adjusting ring 21. This allows the guide protrusion 221 to move within the guide groove 211, while simultaneously driving the adjusting blade 22 to move a certain distance along the radial direction of the adjusting ring 21. In this way, the adjusting blade 22 can move in a direction away from or closer to the center of the adjusting ring 21, thereby increasing or decreasing the opening of the air inlet 202. This increases or decreases the air inlet diameter of the compressor 200, enabling stepless adjustment of the air inlet diameter between the maximum diameter Dmax and the minimum diameter Dmin.

[0044] Furthermore, the guide grooves 211 corresponding to the multiple adjusting blades 22 extend in the same direction, which means that the multiple adjusting blades 22 move in the same direction under the drive of the adjusting ring 21. Moreover, the adjusting blades 22 have a certain length along the circumference of the adjusting ring 21. The multiple adjusting blades 22 are distributed sequentially along the circumference of the adjusting ring 21. The side of the adjusting blades 22 facing the center of the adjusting ring 21 can be constructed as an arc. In this way, when the multiple adjusting blades 22 move away from or close to the center of the adjusting ring 21, they can form an approximate circle, so as to reliably adjust the opening size of the air inlet 202.

[0045] When the adjusting ring 21 rotates in the first direction, multiple guide grooves 211 together drive the corresponding adjusting blades 22 to rotate in the direction of reducing the opening. When it rotates in the second direction, multiple guide grooves 211 together drive the corresponding adjusting blades 22 to rotate in the direction of increasing the opening. The first direction and the second direction are opposite, so that the rotation direction of the adjusting ring 21 is opposite when reducing and increasing the opening, so as to control the reduction and increase of the opening. The first direction can be one of clockwise and counterclockwise, and the second direction can be the other of clockwise and counterclockwise.

[0046] In such Figures 10-15 In the embodiment shown, when the adjusting ring 21 moves in a clockwise direction, it can drive the adjusting blade 22 to rotate in the direction of increasing the opening, and when it moves in a counterclockwise direction, it can drive the adjusting blade 22 to rotate in the direction of decreasing the opening. That is, the first direction is the counterclockwise direction and the second direction is the clockwise direction.

[0047] In some embodiments, one end of the adjusting blade 22 is a rotating fixed end 222 and the other end is configured as a guide connection end 223, a guide protrusion 221 is provided on the guide connection end 223, and the adjusting blade 22 is configured to be rotatable about the rotating fixed end 222 around the guide connection end 223; and / or, in a plurality of adjusting blades 22, at least a portion of any two adjacent adjusting blades 22 are stacked facing each other along the axial direction of the adjusting ring 21.

[0048] Specifically, the adjusting blade 22 and the adjusting ring 21 are connected by the guide protrusion 221 and the guide groove 211. The adjusting blade 22 can rotate under the drive of the adjusting ring 21. One end of the adjusting blade 22 is a rotating fixed end 222 and the other end is a guide connection end 223. The guide connection end 223 is used to connect with the adjusting ring 21. The guide protrusion 221 can be set on the guide connection end 223. The guide connection end 223 is connected to the adjusting ring 21 through the guide protrusion 221, thereby realizing the connection between the adjusting blade 22 and the adjusting ring 21. The rotating fixed end 222 is the rotation center of the adjusting blade 22. The adjusting blade 22 is set so that the guide connection end 223 can rotate around the rotating fixed end 222, so that the rotating fixed end 222 can be fixed, such as by a shaft pin, etc. The adjusting ring 21 can drive the guide connection end 223 to rotate around the rotating fixed end 222 through the guide groove 211 and the guide protrusion 221, so that the adjusting blade 22 can rotate in a direction away from or close to the center of the adjusting ring 21.

[0049] Furthermore, among the multiple adjusting blades 22, at least a portion of any two adjacent adjusting blades 22 are stacked facing each other along the axial direction of the adjusting ring 21. This means that when the multiple adjusting blades 22 are distributed sequentially along the circumference of the adjusting ring 21, portions of two adjacent adjusting blades 22 can be stacked facing each other along the axial direction of the adjusting ring 21, so that the two adjacent adjusting rings 21 partially overlap. This allows the multiple adjusting blades 22 to be connected end to end in sequence to form an approximate circle, thus reliably adjusting the opening size of the air inlet 202.

[0050] In some embodiments, the drive structure includes a drive member 11 and at least one gear set, wherein the at least one gear set is poweredly connected between the drive member 11 and the adjusting ring 21, so that the drive member 11 drives the adjusting ring 21 to rotate.

[0051] Specifically, the drive structure is used to drive the adjustment ring 21 to rotate. The drive structure includes a drive member 11 and at least one gear set. The drive member 11 is used to provide driving force and can be constructed as a drive motor, etc. The at least one gear set is used to transmit power. The at least one gear set is connected between the drive member 11 and the adjustment ring 21 so that the at least one gear set can obtain the driving force of the drive member 11 and transmit the driving force to the adjustment ring 21 to realize the rotation of the adjustment ring 21. In turn, the adjustment ring 21 can drive the adjustment blade 22 to rotate to adjust the opening size of the air inlet 202.

[0052] Among them, at least one gear set is set, that is, the number of gear sets can be one, two, three or more, to ensure that the driving force of the drive component 11 can be transmitted to the adjusting ring 21. When the number of gear sets is at least two, the diameter of at least two gear sets can be reduced, thereby reducing the space occupied by the drive structure.

[0053] In some embodiments, there are two gear sets, namely a first gear set and a second gear set. The first gear set includes an input gear and a first intermediate gear 12 that mesh with each other, and the second gear set includes a second intermediate gear and an output gear 13 that mesh with each other. The input gear is connected to the output end of the drive member 11, the first intermediate gear 12 and the second intermediate gear are coaxially arranged, and the output gear 13 meshes with the adjusting ring 21.

[0054] Specifically, there are two gear sets, which connect the driving member 11 to the adjusting ring 21. The driving member 11 can transmit driving force to the adjusting ring 21 through the two gear sets to drive the adjusting ring 21 to rotate. The two gear sets are the first gear set and the second gear set. The first gear set includes a meshing input gear and a first intermediate gear 12. The second gear set includes a meshing second intermediate gear and an output gear 13. The input gear is connected to the output end of the driving member 11, that is, the input gear can be used to obtain the driving force of the driving member 11, that is, the driving force can be transmitted from the driving member 11 to the first gear set. The input gear meshes with the first intermediate gear 12. The first intermediate gear 12 and the second intermediate gear are coaxially arranged, so that the first intermediate gear 12 can transmit the driving force obtained by the input gear to the second intermediate gear. That is, the first intermediate gear 12 drives the second intermediate gear to rotate under the action of the input gear, that is, the driving force can be transmitted from the first gear set to the second gear set.

[0055] Simultaneously, the second intermediate gear meshes with the output gear 13, allowing the second intermediate gear to further transmit the driving force to the output gear 13, which then outputs power. The output gear 13 meshes with the adjusting ring 21, thus constructing the adjusting ring 21 as a gear ring. The output gear 13 and the adjusting ring 21 are connected through meshing, allowing the output gear 13 to transmit the driving force to the adjusting ring 21, thereby driving the adjusting ring 21 to rotate.

[0056] It should be noted that the diameter of the first intermediate gear 12 is smaller than that of the second intermediate gear, meaning that the driving force can be amplified when it is transmitted from the first gear set to the second gear set.

[0057] In some embodiments, the opening adjustment actuator 100 further includes a plurality of limiting gears 3, which are arranged around the adjustment ring 21 and are all rotatable and respectively mesh with the adjustment ring 21; and / or, at least one of the input gear, the first intermediate gear 12, the second intermediate gear, the output gear 13 and the adjustment ring 21 is provided with a sensing element 4, and the sensing element 4 is correspondingly provided with a position sensor 5, which is used to sense and cooperate with the sensing element 4 to detect the rotation angle of the adjustment ring 21.

[0058] Specifically, the adjusting ring 21 can rotate under the action of the drive structure to drive the adjusting blade 22 to rotate. A limit gear 3 is set in the opening adjustment actuator 100. The limit gear 3 is used to limit the adjusting ring 21 to prevent the adjusting ring 21 from moving during rotation. Multiple limit gears 3 are set, that is, the number of limit gears 3 can be two, three or more, so that multiple limit gears 3 can jointly limit the adjusting ring 21 to improve the reliability of limiting it. The multiple limit gears 3 are set around the adjusting ring 21 so that multiple limit gears 3 can approach the adjusting ring 21 to connect with the adjusting ring 21 and reliably limit the adjusting ring 21.

[0059] Furthermore, all the limiting gears 3 are rotatable and mesh with the adjusting ring 21 respectively. The connection between the limiting gears 3 and the adjusting ring 21 can be achieved through meshing, so that the limiting gears 3 can limit the adjustment ring 21 without restricting the rotation of the adjusting ring 21. Moreover, the multiple limiting gears 3 can be distributed circumferentially along the adjusting ring 21, so that the multiple limiting gears 3 can limit the adjusting ring 21 at multiple positions at the same time, thereby improving the stability of limiting it.

[0060] In such Figure 11 , Figure 12 , Figure 14 and Figure 15 In the embodiment shown, there are three limiting gears 3. The three limiting gears 3 are distributed circumferentially around the adjusting ring 21 and all mesh with the adjusting ring 21, so that the three limiting gears 3 can simultaneously limit the adjusting ring 21 at three positions, which can improve the reliability and stability of limiting the adjusting ring 21.

[0061] Furthermore, at least one of the input gear, the first intermediate gear 12, the second intermediate gear, the output gear 13, and the adjusting ring 21 is provided with a sensing element 4, that is, the number of sensing elements 4 can be at least one. The sensing element 4 is correspondingly provided with a position sensor 5. The position sensor 5 is used to detect the rotation angle of the adjusting ring 21 by sensing the sensing element 4. For example, the sensing element 4 can be set as a magnet, and the position sensor 5 can be constructed as a Hall element. The rotation angle of the adjusting ring 21 can be determined by the cooperation of the Hall element and the magnet, and then the current opening size of the air inlet 202 can be determined.

[0062] In such Figure 11 , Figure 12 , Figure 14 and Figure 15In the illustrated embodiment, a sensing element 4 is provided on the output gear 13. The sensing element 4 can rotate with the rotation of the output gear 13. A position sensor 5 is fixed in the opening adjustment actuator 100. The position sensor 5 can measure the rotation angle of the output gear 13 by cooperating with the magnet, and then determine the rotation angle of the adjustment ring 21, thereby determining the opening size of the air inlet 202. Furthermore, by setting the sensing element 4 on the output gear 13, the rotation angle of the sensing element 4 can be increased through the torque amplification effect, which is beneficial for the position sensor 5 to detect the sensing element 4, and thus facilitates the determination of the rotation angle of the adjustment ring 21.

[0063] In some embodiments, the opening adjustment actuator 100 further includes an actuator housing 6, which is connected to the compressor housing structure 201 of the compressor 200. The drive structure and the adjustment structure 2 are both installed inside the actuator housing 6.

[0064] Specifically, the actuator housing 6 is the external housing structure of the opening adjustment actuator 100. The drive structure and the adjustment structure 2 are both installed inside the actuator housing 6, so that the actuator housing 6 can protect the drive structure and the adjustment structure 2 from damage caused by collisions, etc., and can also prevent dust and other factors from affecting the operation of the drive structure and the adjustment structure 2. The actuator housing 6 is connected to the compressor housing structure 201 of the compressor 200, so that the actuator housing 6 can be connected to the air inlet 202. The adjustment structure 2 is set to correspond with the air inlet 202, so that the opening of the air inlet 202 can be adjusted by adjusting the adjustment structure 2, thereby adjusting the air inlet diameter.

[0065] It should be noted that the actuator housing 6 can be integrally formed, or it can be constructed as several parts connected by bolts or other connectors, so that the actuator housing 6 can reliably protect the drive structure and the adjustment structure 2. The drive component 11, the rotating fixed end 222 of the adjustment blade 22, the position sensor 5, and the limit gear 3 can all be installed on the actuator housing 6. For example, the drive component 11 can be fixedly connected to the actuator housing 6 by bolts or other means, and the limit gear 3 can be rotatably connected to the actuator housing 6 by pins or other means to ensure the reliability of its operation.

[0066] Furthermore, the trim can be adjusted via commands sent from the engine ECU, and the current opening degree of the air intake 202 can be fed back to the ECU for adjustment of the air intake 202 opening size. Figures 1-9 As shown, the opening adjustment actuator 100 has an air inlet 7, an air outlet 8 and an electrical interface 9. The air inlet 7 is connected to the vehicle's pre-compressor pipeline, and the air outlet 8 is connected to the compressor housing structure 201 of the compressor 200. Air enters from the air inlet 7 and then enters the compressor 200 through the air outlet 8. The electrical interface 9 is used to provide power to the electronic control mechanism and to provide signal feedback.

[0067] The present invention also proposes a compressor 200.

[0068] The compressor 200 according to an embodiment of the present invention includes a compressor housing structure 201 and an opening adjustment actuator 100 of any of the above embodiments. An impeller is disposed inside the compressor housing structure 201, allowing external air to enter and be compressed by the impeller. The opening adjustment actuator 100 is connected to the compressor housing structure 201, and the opening of the compressor inlet 202 can be adjusted via the adjustment structure 2, thereby adjusting the inlet diameter. This reduces the inlet diameter of the compressor 200 by decreasing the opening of the inlet 202, thus reducing the trim of the compressor 200 and shifting the surge boundary towards a lower flow rate, thereby ensuring the operating point falls to the right of the surge boundary and reducing the likelihood of surge.

[0069] The present invention also proposes a vehicle.

[0070] The vehicle according to embodiments of the present invention includes an opening adjustment actuator 100 of any of the above embodiments or a compressor 200 of the above embodiments. By providing the opening adjustment actuator 100 or the compressor 200, the intake diameter of the compressor 200 can be adjusted. Thus, by reducing the opening of the intake port 202, the intake diameter of the compressor 200 can be reduced, thereby reducing the trim of the compressor 200, causing the surge boundary to move towards the direction of low flow, so that the operating point can fall to the right of the surge boundary, reducing the possibility of surge phenomenon and improving the high-altitude performance of the engine.
