Abstract
Description
Technical Field
[0001] This application relates to the field of vortex fluid machinery technology, and in particular to a variable volume vortex mechanism. Background Technology
[0002] Vortex fluid machinery, as energy storage and power equipment, is widely used in various fields of society. It is one of the core equipment in refrigeration, gas separation and defense industries. Among them, vortex compressors, vortex expanders and vortex liquid pumps are the most common types of vortex fluid machinery.
[0003] The main components of a scroll compressor include a frame, main shaft, anti-rotation mechanism (such as an eccentric shaft or cross ring), moving plate, and fixed plate. The scroll teeth of the moving plate and the fixed plate mesh to form a compression cavity, compressing the gas as the moving plate moves. Due to the overturning moment exerted by the gas force on the moving plate, the moving plate is prone to tilting, and the scroll teeth of the moving plate are prone to colliding with the scroll teeth of the fixed plate, which limits the design dimensions of the scroll teeth.
[0004] Differential control using electromagnets on both sides of the moving plate can overcome the overturning moment on the moving plate through a linear control system. However, this method requires a large number of electromagnets, resulting in significant size and weight, leading to high power consumption and overall cost. Even using two electromagnets on a single side of the moving plate (on the frame or fixed plate) for differential control in a single degree of freedom to control the tilt of the moving plate in that degree of freedom still results in partial cancellation of the attractive force in that single degree of freedom due to the differential control method. This leads to a continued problem of a large number of electromagnets, significant size and weight, high power consumption, and high overall cost. Summary of the Invention
[0005] In view of this, the main technical problem to be solved by this application is to provide a variable-capacity scroll mechanism that can prevent the tilt of the moving plate, reduce the number of control magnets and control circuits used, avoid the loss caused by partial magnetic force cancellation in differential control, change the exhaust volume of the scroll mechanism, and thus improve the working efficiency of the scroll mechanism.
[0006] To solve the aforementioned technical problems, this application adopts the following technical solution: a variable-capacity scroll mechanism. This variable-capacity scroll mechanism includes a frame, a fixed disk, and a moving disk, wherein the fixed disk is fixed to the frame, and the moving disk is located between the frame and the fixed disk. The variable-capacity scroll mechanism also includes an electromagnet control mechanism, which includes a control magnet, a controlled magnet, and displacement sensors. The control magnet is mounted on the fixed disk or the frame, the controlled magnet is mounted on the moving disk, and the displacement sensors include a first displacement sensor, a second displacement sensor, and a third displacement sensor. The first, second, and third displacement sensors detect the positions of any three points on the surface of the moving disk in real time along a first reference line to obtain the displacement of the moving disk and its tilt angle in two directions within the disk surface. The control magnet exerts an attractive or repulsive force on the controlled magnet to centrally control the position of the moving disk along the first reference line and the tilt state of the moving disk. The first reference line coincides with the central axis of the base circle of the scroll teeth of the fixed disk.
[0007] This application provides a variable-capacity scroll mechanism, which includes an electromagnet control mechanism. A displacement sensor obtains the displacement of the moving plate and its tilt angle in two directions within the plate surface. A control magnet on the frame or fixed plate generates an attractive or repulsive force on a controlled magnet on the moving plate, thereby centrally controlling the position and tilt of the moving plate in the first reference line direction. This helps prevent tilting of the moving plate, changes its position in the first reference line direction, and provides conditions for increasing or decreasing the capacity of the scroll mechanism. Furthermore, it reduces the number of control magnets and control circuits required, avoids losses caused by partial magnetic force cancellation in differential control, and ultimately improves the working efficiency of the scroll mechanism.

Detailed Implementation
[0009] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0010] To address the problems of tilting of the moving plate, the large number of control magnets and control circuits used in related technologies, and the losses caused by partial magnetic force cancellation in differential control, some embodiments of this application provide a variable-capacity scroll mechanism. This variable-capacity scroll mechanism includes a frame, a fixed plate, and a moving plate, wherein the fixed plate is fixed to the frame, and the moving plate is located between the frame and the fixed plate. The variable-capacity scroll mechanism also includes an electromagnet control mechanism, which includes a control magnet, a controlled magnet, and displacement sensors. The control magnet is disposed on the fixed plate or the frame, the controlled magnet is disposed on the moving plate, and the displacement sensors include a first displacement sensor, a second displacement sensor, and a third displacement sensor. The first, second, and third displacement sensors detect the positions of any three points on the surface of the moving plate in real time along a first reference line to obtain the displacement of the moving plate and its tilt angle in two directions within the plate surface. The control magnet exerts an attractive or repulsive force on the controlled magnet to centrally control the position of the moving plate along the first reference line and the tilt state of the moving plate. The first reference line coincides with the central axis of the base circle of the scroll teeth of the fixed plate. The following is a detailed explanation.
[0011] See Figures 1 to 3 , Figure 1 This is a three-dimensional external structural diagram of the variable capacity vortex mechanism provided in some embodiments of this application. Figure 2 This is a side view diagram of the variable capacity vortex mechanism provided in some embodiments of this application. Figure 3 yes Figure 1The diagram shows a cross-sectional view of the variable displacement scroll mechanism. It should be noted that the variable displacement scroll mechanism provided in this application can be applied to scroll compressors, scroll expanders, and scroll liquid pumps, among other scroll fluid machinery. The internal structures of these three are identical; the only difference lies in the working medium or direction of motion. The following embodiments use a scroll compressor as an example to illustrate the specific application of the variable displacement scroll mechanism, and do not limit the specific application of the variable displacement scroll mechanism of this invention.
[0012] In some embodiments of this application, the variable-capacity scroll mechanism includes a frame 10, a fixed disk 20, and a moving disk 30. See also Figure 4 , Figure 4 This is a schematic diagram of the frame 10 provided in some embodiments of this application. The frame 10 is the core support and positioning structure of the variable capacity scroll mechanism. The fixed plate 20 is fixed to the frame 10. The moving plate 30 is located between the frame 10 and the fixed plate 20, that is, the moving plate 30 is located in the space formed by the docking of the frame 10 and the fixed plate 20. The variable capacity scroll mechanism also includes an electromagnet control mechanism. In some embodiments, since the scroll teeth of the moving plate 30 extend from the plate surface of the moving plate 30 like a cantilever structure, the gas force and centrifugal force of the compressed cavity generate an overturning moment on the moving plate 30, causing the moving plate 30 to easily tilt. Therefore, an electromagnet control mechanism is provided in the variable capacity scroll mechanism to control the tilt of the moving plate 30.
[0013] The electromagnet control mechanism includes a control magnet 40, a controlled magnet 50, and a displacement sensor 60. The control magnet 40 is mounted on either the fixed plate 20 or the frame 10. That is, the control magnet 40 can be mounted on either the fixed plate 20 or the frame 10. This embodiment uses the example of the control magnet 40 being mounted on the fixed plate 20 for illustrative purposes only and does not limit the mounting method of the control magnet 40 in this embodiment. The controlled magnet 50 is mounted on the moving plate 30. See also... Figure 5 , Figure 5 This is a schematic diagram of the structure of a displacement sensor 60 provided in some embodiments of this application. The displacement sensor 60 includes a first displacement sensor 601, a second displacement sensor 602, and a third displacement sensor 603. The first displacement sensor 601, the second displacement sensor 602, and the third displacement sensor 603 can be disposed at any position on the fixed plate 20. Of course, in some other embodiments where the control magnet 40 is disposed on the frame 10, the first displacement sensor 601, the second displacement sensor 602, and the third displacement sensor 603 can also be disposed at any position on the frame 10. This application does not specifically limit the position of the displacement sensor 60.
[0014] The first displacement sensor 601, the second displacement sensor 602, and the third displacement sensor 603 can detect any three points on the surface of the moving disk 30 on the first reference line (e.g., Figure 3The position of the moving disk 30 in the Z direction (as shown in the figure below) is detected in real time. Based on the detection results, the displacement z of the moving disk 30 and the tilt angle of the moving disk 30 in two directions (i.e., the x direction and the y direction) within the disk surface can be calculated.
[0015] The control magnet 40 can generate an attractive or repulsive force on the controlled magnet 50, thereby centrally controlling the position and tilt state of the moving disk 30 in the direction of the first reference line. The first reference line coincides with the central axis of the base circle of the volute teeth of the fixed disk 20. The first reference line can be used to determine the reference direction of the control moving disk 30.
[0016] The variable-capacity scroll mechanism provided in some embodiments of this application includes an electromagnet control mechanism. A displacement sensor can obtain the displacement of the moving disk and its tilt angle in two directions within the disk surface. Furthermore, a control magnet 40 can centrally control the position and tilt state of the moving disk 30 along the first reference line, thereby preventing tilting of the moving disk 30 and changing its position along the first reference line. This structure provides conditions for increasing and decreasing the capacity of the scroll mechanism, reduces the number of control magnets 40 and control circuits required, avoids losses caused by partial magnetic force cancellation in differential control, and improves the working efficiency of the scroll mechanism.
[0017] In some embodiments, the displacement sensor 60 is a self-inductance displacement sensor. The self-inductance displacement sensor and the electromagnet in the control magnet 40 are integrated into one structure. In other embodiments, the displacement sensor 60 may also be a separate structure used in combination with the electromagnet. In other words, the displacement sensor 60 of this application may be a self-inductance displacement sensor integrated with the electromagnet, or it may be independent of it. This application does not specifically limit the arrangement of the displacement sensor 60.
[0018] In some embodiments, a coordinate system is established with the initial position of the center of mass of the moving disk as the origin. The displacement z of the center of mass of the moving disk in the direction of the first reference line and the tilt angles of the moving disk 30 in the x and y directions parallel to the disk surface are calculated according to the following coordinate transformation formula:
[0019] Where, θ x For the rotating disk 30, the angle θ around the x-direction is parallel to the x-direction. y Let z be the rotation angle of the moving disk 30 about a direction parallel to the y-direction, z be the displacement of the center of mass of the moving disk in the direction of the first reference line, and x be the displacement of the moving disk's center of mass. mn and y mn (n=1, 2, 3) represent the initial positions of the first displacement sensor 601, the second displacement sensor 602, and the third displacement sensor 603 on the surface of the moving disk 30, respectively. mLet z be the initial position of any point on the disk surface of the moving disk 30 in the direction of the first reference line. n (n=1, 2, 3) represents the positions of any three points on the surface of the moving disk 30 in real time, detected by the first displacement sensor 601, the second displacement sensor 602, and the third displacement sensor 603, in the direction of the first reference line.
[0020] It should be noted that the x-direction is any direction parallel to the surface of the moving disk 30 and passing through the center of mass of the moving disk, while the y-direction is parallel to the surface of the moving disk 30, passes through the center of mass of the moving disk, and is perpendicular to the x-direction. The real-time position z is obtained by detecting the first displacement sensor 601, the second displacement sensor 602, and the third displacement sensor 603. n With initial position x mn y mn and z m By performing coordinate transformation, the displacement z of the center of mass of the moving disk in the direction of the first reference line and the rotation angle θ of the moving disk 30 around the direction parallel to x can be calculated. x The moving disk 30 rotates around an angle θ parallel to the y-direction. y .
[0021] See Figure 6 , Figure 6 This is a schematic diagram of the structure of the control magnet 40 provided in some embodiments of this application. In some embodiments, the control magnet 40 further includes a first control magnet 401, a second control magnet 402, and a third control magnet 403. The first control magnet 401, the second control magnet 402, and the third control magnet 403 are distributed circumferentially along the end face of the frame 10 or the disk surface of the fixed plate 20. In some embodiments, the first control magnet 401, the second control magnet 402, and the third control magnet 403 may be distributed circumferentially along the disk surface of the fixed plate 20 (e.g., Figure 6 (As shown). In some embodiments, the first control magnet 401, the second control magnet 402, and the third control magnet 403 may also be distributed circumferentially along the end face of the frame 10. This application achieves centralized control of the moving disk 30 by setting only three control magnets 40, namely the first control magnet 401, the second control magnet 402, and the third control magnet 403, reducing the number, volume, and weight of electromagnets, thereby reducing power consumption and solving the problem of high cost of vortex mechanisms.
[0022] In some embodiments, the control magnet 40 and the controlled magnet 50 are configured such that, at any given time, the projections of the working end face of the control magnet 40 and the working end face of the controlled magnet 50 in the direction of the first reference line overlap. In some embodiments, at any given time, the projection of the working end face of the controlled magnet 50 in the direction of the first reference line is located within the projection range of the working end face of the control magnet 40 in the direction of the first reference line. Therefore, the attractive or repulsive force exerted by the control magnet 40 on the controlled magnet 50 can be maximized to ensure real-time control of the position and tilt state of the moving disk 30 in the direction of the first reference line.
[0023] In some embodiments, the control magnet 40 includes an electromagnet; or, the control magnet 40 includes an electromagnet and a permanent magnet material. In other words, the control magnet 40 may only include an electromagnet. The number of electromagnets corresponds to the number of control magnets 40, i.e., the number of electromagnets is three. The three electromagnets correspond one-to-one with the first control magnet 401, the second control magnet 402, and the third control magnet 403, i.e., the three electromagnets are distributed circumferentially along the end face of the frame 10 or the surface of the fixed plate 20. The electromagnets can generate controllable electromagnetic force. By applying this electromagnetic force to the controlled magnet 50 on the moving plate 30, the overturning torque of the moving plate 30 can be counteracted in real time, thereby actively maintaining the attitude balance of the moving plate 30. Of course, the control magnet 40 may also include a combination of electromagnets and permanent magnet materials. The permanent magnet material itself can generate a magnetic force of constant strength, i.e., a permanent magnet force. The permanent magnetic force exerted by the permanent magnet material on the controlled magnet 50 does not consume electrical energy. Therefore, its combined action with the electromagnetic force generated by the electromagnet can reduce steady-state energy consumption during the control process. It should be noted that permanent magnet materials may or may not be used in the control magnet 40; this application does not impose any specific limitations on this.
[0024] See Figure 7 , Figure 7This is a schematic diagram of the structure of the electromagnet coil 404 provided in some embodiments of this application. The electromagnet includes the electromagnet coil 404 and the electromagnet core. A controlled current can be passed through the electromagnet coil 404. By controlling the current in the electromagnet coil 404, the electromagnetic force generated by the electromagnet can be adjusted. The electromagnet core can concentrate the magnetic lines of force generated by the electromagnet coil 404 and guide the magnetic field energy to the air gap. The electromagnet core includes electromagnet teeth and electromagnet yoke. The electromagnet teeth face the controlled magnet 50 to ensure that the electromagnetic force is accurately applied to the corresponding position of the controlled magnet 50. The electromagnet yoke is the main back structure connecting the electromagnet teeth, which can form a closed loop and has a structural support function. The electromagnet magnetic field forms a loop through the electromagnet core, the magnetic material of the moving disk 30, and the gap between the moving disk 30 and the fixed disk 20, thereby generating an electromagnetic force and acting on the moving disk 30. In some embodiments, the axial projection of the electromagnet teeth falls within the axial projection range of the magnetic material of the moving disk 30 at any given time, thereby maximizing the utilization of the area of the electromagnet teeth.
[0025] In some embodiments, at least one electromagnet may include multiple electromagnet coils 404 electrically connected together. A single electromagnet may include multiple magnetic poles distributed at different locations to generate a specific magnetic field distribution, thereby meeting specific application requirements. This electromagnet with multiple magnetic poles can be electrically connected together by multiple electromagnet coils 404 and considered as a single electromagnet; in this way, multiple spatially separated magnetic poles can be precisely manufactured. In other embodiments, a single electromagnet may include electromagnet coils 404 wound from the same wire.
[0026] See Figure 8 , Figure 8 This is a schematic diagram of the electromagnet's sinusoidal current and the high-frequency small signal of the self-inductance displacement sensor provided in some embodiments of this application. By adding a high-frequency small signal to the electromagnet's sinusoidal current and extracting the voltage change of the high-frequency small signal, the position of the moving disk 30 in the direction of the first reference line can be obtained. The sinusoidal current is mainly used to generate the control electromagnetic force. The high-frequency small signal can reduce the interference of the sinusoidal current on the signal.
[0027] In some embodiments, the electromagnet control mechanism further includes a controller. The controller is used to control the position change and tilt state of the moving disk 30 in real time during the variable-capacity vortex mechanism. The controller can adjust the position z of the moving disk 30 in the first reference line direction and the rotation angle θ of the moving disk 30 about the x-direction. x The moving disk 30 rotates around an angle θ parallel to the y-direction. yThe required current is obtained from the three electromagnet coils 404. Furthermore, the controller can control the drive circuit to input the corresponding current to the three electromagnets respectively, thereby controlling the magnitude of the electromagnetic force exerted by the electromagnets on the controlled magnet 50, so as to control the new position and tilt angle of the moving disk 30 in the direction of the first reference line.
[0028] In some embodiments, the controlled magnet 50 includes a first controlled magnet, a second controlled magnet, and a third controlled magnet. The first controlled magnet, the second controlled magnet, and the third controlled magnet are distributed circumferentially along the surface of the movable disk 30. The controlled magnets 50 can form a magnetic circuit to ensure that the control magnet 40 can generate an attractive or repulsive force on the controlled magnets 50, thereby centrally controlling the position and tilt state of the movable disk 30.
[0029] In some embodiments, the controlled magnet 50 further includes a permanent magnet material and / or a magnetically conductive material. Specifically, the controlled magnet 50 may be made solely of a permanent magnet material. The permanent magnet material can provide the controlled magnet 50 with a constant static magnetic field that does not require external energy to maintain, thus the controlled magnet 50 itself is magnetic. Alternatively, the controlled magnet 50 may be non-magnetic and made solely of a magnetically conductive material. The magnetically conductive material is disposed at corresponding positions on the electromagnet teeth. When the controlled magnet 50 itself is non-magnetic, the control magnet 40 can apply a magnetic effect to the controlled magnet 50, causing the controlled magnet 50 to generate corresponding magnetism. Of course, the controlled magnet 50 may also be made from a combination of a permanent magnet material and a magnetically conductive material.
[0030] See Figure 1 and Figure 9 . Figure 9 This is a schematic diagram of the spindle assembly 70 provided in some embodiments of this application. In some embodiments, the variable displacement scroll mechanism further includes the spindle assembly 70. The spindle assembly 70 can drive the movable disk 30 to move, so that the scroll teeth of the movable disk 30 and the scroll teeth of the fixed disk 20 cooperate with each other to continuously compress the gas in the compression cavity formed by the movable disk 30 and the fixed disk 20. The spindle assembly 70 includes a spindle 701, a front support bearing 702, a rear support bearing 703, and a drive bearing 704. The spindle 701 is mounted on the frame 10 through the front support bearing 702 and the rear support bearing 703, connected to the motor output shaft, and can rotate on the frame 10 about its axial direction. The drive bearing 704 is embedded in the bearing hole of the movable disk 30 and cooperates with the eccentric shaft section of the spindle assembly 70.
[0031] See Figure 10 , Figure 10This is a schematic diagram of the eccentric shaft assembly 80 provided in some embodiments of this application. In some embodiments, the variable displacement scroll mechanism further includes the eccentric shaft assembly 80. The eccentric shaft assembly 80 is disposed between the frame 10 and the moving disk 30. The eccentric shaft assembly 80 can prevent the moving disk 30 from rotating, thus maintaining the correct positional relationship between the moving disk 30 and the fixed disk 20. The eccentric shaft assembly 80 includes an eccentric shaft 801, a first eccentric shaft bearing 802, and a second eccentric shaft bearing 803. The eccentric shaft 801 is mounted on the moving disk 30 via the first eccentric shaft bearing 802, and on the frame 10 via the second eccentric shaft bearing 803.
[0032] The variable-capacity vortex mechanism provided in some embodiments of this application centrally controls the moving disk 30 through an electromagnet control mechanism. The displacement of the moving disk in the direction of the first reference line and the tilt angle of the moving disk in two directions within the disk surface are obtained through a displacement sensor. The control magnet 40 generates an attractive or repulsive force on the controlled magnet 50 to centrally control the position of the moving disk 30 in the direction of the first reference line and the tilt state of the moving disk 30, thereby preventing the moving disk 30 from tilting and providing conditions for increasing or decreasing the capacity of the vortex mechanism. This helps to reduce the number of control magnets 40 and control circuits used, avoids the losses caused by partial magnetic force cancellation in differential control, and achieves the purpose of improving the working efficiency of the vortex mechanism.
