Abstract
Description
Technical Field
[0001] The present invention relates to the field of compressors, and in particular to a compressor assembly and a vehicle. Background Art
[0002] The biggest challenge in compressor applications for refrigeration lines lies in the refrigeration system's desire to completely seal the motor within the piping. As part of the piping, refrigerant leakage must be prevented. For external power output, the system requires a simple design that facilitates connection and design. Opposite-shaft motors, the simplest power output method, present dynamic sealing challenges.
[0003] In summary, the development of such a device inevitably involves conflicts and trade-offs between the following three points:
[0004] 1. The compressor motor needs to be immersed in the refrigerant circulation path, which is conducive to motor heat dissipation. However, because the refrigerant circulation path is best to control leakage, the motor housing is best sealed;
[0005] 2. For compressor motor power output, opposing shafts are the most common approach. However, the high-speed rotation of the dynamic seal between the shaft and the housing can be a significant challenge. This is especially true given the harsh environment of automotive motors, where dynamic seals can have a significant impact on their lifespan.
[0006] 3. If the design of immersing the compressor motor in the refrigerant is abandoned, the motor will face the challenge of having to significantly increase its size and cost due to poor heat dissipation.
[0007] In short, traditional designs cannot achieve a combination of reliable sealing, cheap high-power density motors, and simple shaft output power, and must compromise on one or the other. Summary of the Invention

[0032] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.
[0033] The terms "up," "down," "left," "right," "front," "back," "front," "back," "top," and "bottom" mentioned or potentially mentioned in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may vary depending on their location or usage. Therefore, these or other directional terms should not be interpreted as restrictive. In addition, the terms "first," "second," "third," and similar expressions are used only for descriptive and distinguishing purposes and should not be understood to indicate or imply the relative importance of the corresponding components.
[0034] refer to Figures 1 to 3 , which respectively show a schematic diagram of a compressor assembly according to the present invention, Figure 1 a schematic diagram of a compressor assembly with the movable stator in a first working position, and Figure 1 Schematic diagram of a compressor assembly with the movable stator in a second working position.
[0035] The compressor assembly 1 has a power output, wherein the compressor assembly 1 includes a movable stator 11, a compressor 14, a stroke structure 15 (in Figure 4 and Figure 5As shown in the figure, the movable stator 11 is provided with a power output rotor 12 and a compressor-side rotor 13 that can rotate independently of each other. The compressor-side rotor 13 is connected to the compressor 14. The stroke structure 15 is used to move the movable stator 11, and the movable stator 11 has a first working position and a second working position. In the first working position, the magnetic field of the movable stator 11 is coupled with the magnetic field of the power output rotor 12 and drives the power output rotor 12 to rotate to output power. That is, when the stator provides a rotating magnetic field, it drives the power output rotor 12 to output power, for example, as auxiliary power for driving a vehicle. In the second working position, the magnetic field of the movable stator 11 is coupled with the magnetic field of the compressor-side rotor 13 and drives the compressor-side rotor 13 to rotate to drive the compressor 14 to operate. That is, when the stator provides a rotating magnetic field, it drives the compressor-side rotor 13 to rotate, driving the compressor 14 to work, for example, for compressing refrigerant to operate the air conditioning system. This variable motor structure allows the motor originally used for the compressor to switch between two modes, thereby achieving the purpose of outputting power to the outside.
[0036] It should be understood that "the stroke structure 15 is used to move the movable stator 11" includes the situation where the stroke structure directly drives the movable stator to move, and also covers the situation where the stroke structure drives the movable stator in an indirect manner, for example, the stroke structure first directly drives an intermediate component to move, and the intermediate component then directly drives the movable stator to move. Both of the above situations fall within the scope of protection of the present disclosure. In addition, "the compressor side rotor 13 is connected to the compressor 14" means that the compressor side rotor can be connected to a component of the compressor, for example, it is non-rotatably connected, so that the compressor side rotor can drive the component of the compressor to rotate together, thereby realizing the main function of the compressor. In the figure, the first working position is the position where the movable stator is at the left rotor (i.e., the power output rotor 12), and the second working position is the position where the movable stator is at the right rotor (i.e., the compressor side rotor 13). If necessary, the movable stator may also have other working positions or transition positions, which are not excluded from the scope of protection of the present disclosure. In addition, those skilled in the art should know that the magnetic field coupling between the stator and the rotor means that the stator and the rotor can be regarded as a functioning motor at this time. Therefore, the present technical solution can achieve the switching of two motors with different uses by moving the movable stator, thereby achieving two working modes, thereby achieving the purpose of the invention. Finally, the name "compressor side rotor" does not necessarily mean that the rotor needs to be close to the compressor, nor does it necessarily require that the rotor is closer to the compressor than the power output rotor. It is named so because it is connected to the compressor. Those skilled in the art know that the positional relationship and the distance, quantity, and even specifications, shapes, etc. between the various parts can be adjusted according to actual requirements and actual applications. Various adjustments are applicable to the embodiments of the present disclosure.
[0037] Compared with the technical solution of independent motor and compressor, the present invention is cheaper as a whole, smaller in size, highly integrated in structure, and the motor has better heat dissipation.
[0038] refer to Figure 4 and Figure 5 , which respectively show a structural diagram of a compressor assembly according to the present invention, wherein the movable stator is in a first working position; and Figure 4 A compressor assembly wherein the movable stator is in a second working position.
[0039] As can be seen from the figure, the compressor assembly 1 includes a shell 16, the movable stator 11, the compressor 14, the stroke structure 15 and the compressor side rotor 13 are arranged in the shell 16 in a sealed manner relative to the outside world, and the power output rotor 12 is partially arranged in the shell 16 in a sealed manner relative to the outside world, and partially extends outside the shell 16.
[0040] It should be understood that the housing 16 is used to protect and seal the various parts inside it, and except for the power output rotor 12 and the first bearing 20 arranged on the outside thereof, other parts (including the parts mentioned below) are all protected and sealed and arranged inside the housing 16. In other words, this embodiment uses the housing to achieve sealing. Compared with the direct shaft output solution of the prior art, the present invention does not have a dynamic seal, has a longer design life, better reliability, and is easy to maintain and repair after a refrigerant leak. When in use, the motor and compressor may be used to be sealed in a refrigeration pipeline or in a refrigerant circulation loop or system. Therefore, the significance of this design is clearly reflected, and it can take into account the three conflicts mentioned in the background technology. For example, it can be clearly seen from the figure that, except for the space for arranging the power output rotor 12 and its first bearing 20, the entire housing 16 is a closed structure, including a portion supporting the first bearing 20 and a portion supporting the second bearing 21 of the compressor-side rotor 13 (which is arranged on the right side of the compressor-side rotor 13). A portion of the power output rotor 12 extends out of the housing 16. Specifically, in the figure, the rotor axially extends to the left (or outward) beyond the first bearing 20 and the edge of the housing 16 to better connect with the components that require power output transmission.
[0041] In addition, in some embodiments, the compressor assembly further includes a third bearing 22 and a fourth bearing 23, which are respectively arranged on the right side of the power output rotor 12 and the left side of the compressor side rotor 13. Specifically, the third bearing 22 is arranged within the stroke structure 15, and the fourth bearing 23 is arranged on the right side of the compressor 14 (such as the movable scroll 142 mentioned below). The design of multiple bearings on both sides of the corresponding rotor can more stably support the rotation of the rotor. In this regard, the housing 16 is also designed with a corresponding bearing support portion 161 inside, which extends from the inner side of the outer wall of the housing 16 to the fourth bearing 23, and is therefore located between the compressor side rotor 13 and the compressor 14 (such as the movable scroll 142 mentioned below), while ensuring the support for the corresponding bearings and maintaining the sealing of the right-side parts.
[0042] Regarding the design of the stroke structure 15, illustratively, the stroke structure 15 is constructed as an axial stroke structure to enable the movable stator 11 to move axially. It should be understood that the axial direction here can refer to the axial direction of the entire compressor assembly, or it can be understood in terms of the extension direction of the rotor shaft, which is the left-right direction in the figure. As a result, the power output rotor 12 and the compressor-side rotor 13 are coaxially designed, facilitating the movable stator to switch between the two magnetic field coupling and combined motors by simple axial movement.
[0043] Compared to other integrated motor sealing solutions, the present invention uses an axial travel structure that can switch between modes, ensuring greater efficiency in both modes, more efficient magnetic field coupling, and less waste. This allows for more efficient use of relatively expensive materials (such as copper wire and silicon steel sheets).
[0044] More specifically, the stroke structure 15 can be constructed as an electromagnetic attraction device, that is, it generates an attraction or repulsion force by electromagnetic action with related parts (such as the static vortex 141 mentioned below), thereby achieving the movement effect of the movable stator. In other words, the stroke structure 15 itself is fixed and achieves the purpose of movement by electromagnetic action. Those skilled in the art should know that the parts involved (such as the static vortex 141) are made of materials that support such electromagnetic action. The advantages of this design include that the stroke structure 15 does not need to be moved, so its position is stable, and it has little contact with the mating parts, which increases their service life. Compared with a purely mechanical contact method, this electromagnetically triggered movement method can also reduce noise, improve movement stability and accuracy, and facilitate remote control when needed, such as adjusting the electromagnetic force to adjust the size and opening and closing of the attraction or repulsion force, thereby achieving speed adjustment and switching of the stator movement.
[0045] As can be seen, in this embodiment, the mode switching mechanism is designed as a micro-stroke structure, actuated by an electromagnet or other actuator installed between the components. This small stroke allows for a very compact system design. Furthermore, the entire movable stator structure is immersed in the refrigerant and lubricant oil-mixed pipeline during use, ensuring that the micro-stroke structure and the guide rails between the housing and the movable stator are fully lubricated. Consequently, high reliability throughout the entire lifecycle is ensured.
[0046] In order to better realize the switching between the two working modes, especially to make the moving stroke of the movable stator 11 shorter and the size smaller, so that the entire compressor assembly is more compact, the life and switching efficiency of the moving parts are improved, the manufacturing cost is saved, the magnetic field circuit is easier to design, and the operation is more reliable, exemplarily, the compressor assembly 1 also includes a power output side stator 17 fixed in a position for magnetic field coupling with the power output rotor 12 and a compressor side stator 18 fixed in a position for magnetic field coupling with the compressor side rotor 13, the power output side stator 17 and the compressor side stator 18 are sealed relative to the outside world and arranged in the outer casing 16, the movable stator 11 is arranged between the power output side stator 17 and the compressor side stator 18, in the first working position, the movable stator 11, the power output side stator 17 and the power output rotor 12 constitute a power output motor to work, and in the second working position, the movable stator 11, the compressor side stator 18 and the compressor side rotor 13 constitute a compressor side motor to work.
[0047] Those skilled in the art will appreciate that the specific motor to be activated can be determined by adjusting the air gap size of the corresponding motor. Those skilled in the art will also appreciate that the air gap refers to the distance from the magnetic material on one side of the stator to the magnetic material on the other side. Generally, since the stator contains both conductive material and magnetic material, the distance between the magnetic material and the stator is the distance between them. Thus, in the first operating position, the right air gap increases, while the left air gap decreases. The movable stator, the power take-off rotor, and the power take-off side stator together form a complete motor, whose power is output outward along the output shaft of the power take-off rotor. In the second operating position, the left air gap increases, while the right air gap decreases. The magnetic lines of force on the left side escape from the outer stator and primarily pass through the air gap, significantly increasing the magnetic resistance of the magnetic circuit and reducing its ability to drive the power take-off rotor. Similarly, because the right air gap is compressed, the compressor side rotor can operate at full power. That is, the movable stator, the compressor side rotor, and the compressor side stator together form a complete motor. As will be introduced below, this motor is connected to the compressor's movable scroll due to its mechanical structure. At this time, the complete power is output to the scroll through the compressor side rotor, completing the compressor's main function.
[0048] The power output side stator 17 and the compressor side stator 18 are respectively arranged on the left and right sides of the housing 16, and are both on the outside relative to the corresponding rotors. In other words, these two stators and the corresponding rotors have already formed a part of the motor in advance. As long as the movable stator 11 is moved to the first or second working position respectively, it can form a complete motor with the corresponding fixed stator and rotor to complete the activation of the corresponding working mode. It can also be understood that the power output side stator 17 and the compressor side stator 18 assume part of the stator function of the movable stator 11, so the moving stroke of the movable stator 11 can be smaller, and its size can also be designed to be smaller, and the above-mentioned technical effects can be achieved. In addition, the movable stator 11, the power output side stator 17 and the compressor side stator 18 can be designed to be annular, which is a stator structure of axial magnetic flux.
[0049] The compressor 14 includes a fixed scroll 141 and a movable scroll 142. The fixed scroll 141 is connected to the movable stator 11 as an integral unit and is arranged between the movable scroll 142 and the power output rotor 12. The movable scroll 142 is connected to the compressor side rotor 13. In the first working position, the fixed scroll 141 and the movable scroll 142 are separated from each other. In the second working position, the fixed scroll 141 and the movable scroll 142 are sealed together.
[0050] In the case of this design, the static scroll 141 moves together with the movable stator 11, thereby being able to simultaneously realize the working mode switching caused by the movement of the stator and the release and activation effects of the compressor function. In addition, those skilled in the art should be aware of the respective working principles of the dynamic and static scrolls and the compression effects that can be produced by their cooperation. For example, the dynamic scroll can be connected to the compressor side rotor 13 on the right side through a certain transmission and positioning mechanism. As the compressor side rotor rotates, the dynamic scroll will perform circular motion, thereby achieving step-by-step compression of the gas. It should be noted that each scroll can be constructed as a digital scroll or a non-digital scroll. The present disclosure takes the digital scroll as an example, because its integrated structure can make the mechanical structure more simplified, thereby giving full play to the advantages of the present invention.
[0051] In some embodiments, the stroke structure 15 is arranged inside the movable stator 11 and between the static vortex 141 and the power output rotor 12 (specifically, the stroke structure is located on the left side of the static vortex), and the stroke structure 15 is used to move the static vortex 141 together with the movable stator 11.
[0052] It can be seen that the stroke structure 15 indirectly drives the movable stator 11 to move by driving the fixed scroll 141. Since the fixed scroll 141 and the movable stator 11 are integrated, the movement of the two is still synchronized. That is, there is no substantial difference between direct drive and indirect drive. On the contrary, indirect drive can also simultaneously achieve the deactivation or activation of the compressor function. In addition, this technical solution allows the stroke structure 15 to be arranged in a central position, thereby freeing up the outer space for the installation and arrangement of the movable stator 11.
[0053] Relying on the structural changes of the motor magnetic circuit and vortex disk brought about by the small axial stroke of the movable stator described above, this embodiment can simultaneously achieve the reduction of compressor load, change of motor structure and mode switching. Both the normal operation of the compressor and the power output of the motor are taken into account in an extremely compact volume. Compared with a larger stroke, it saves space, the magnetic field circuit is easy to design, and the operation is more reliable. At the same time, compared with other dual-rotor solutions, this embodiment can achieve a high degree of coupling of the magnetic circuit, can output torque delicately and efficiently, and the speeds on both sides can also be completely decoupled, simplifying the difficulty and complexity of the overall control.
[0054] The compressor assembly 1 further includes a sealing cover plate 19, one longitudinal end of the sealing cover plate 19 abuts against the inner circumferential surface of the outer wall of the casing 16, and the other longitudinal end abuts against the stroke structure 15, and the sealing cover plate 19 is arranged between the stroke structure 15 and the power output rotor 12. In the first working position, the movable stator 11 abuts against the sealing cover plate 19, and in the second working position, the movable stator 11 is separated from the sealing cover plate 19.
[0055] The longitudinal direction of the sealing cover plate 19 refers to its length direction or the up-down direction in the figure. In different working positions, the purpose of the contact and separation between the movable stator and the sealing cover plate is also to meet the requirements of different air gap sizes, so as to achieve the activation of different motors. It can be seen that with the help of the sealing cover plate 19 and other parts, the interior of the entire housing 16 is divided into several sealed inner cavities, which are used to respectively arrange: the power output rotor, the power output side stator; the movable stator, the stroke structure, the movable and static scrolls, and the third bearing; the compressor side rotor, the second bearing, and the compressor side stator. The solution of the present invention can prevent refrigerant leakage by making a complete static seal on the stator cavity, wherein the coupled magnetic circuit of the stator and rotor simultaneously achieves the effects of sealing and magnetic field penetration through a material that can pass through the magnetic field. After a certain stroke change, a part of the electromagnetic structure of the compressor assembly can be efficiently used in another mode to achieve the purpose of outputting power to the outside.
[0056] The sealing cover plate 19 can be made of a non-conductive, non-magnetic material, such as a polymer engineering plastic, more specifically ABS (Acrylonitrile Butadiene Styrene). ABS plastic combines the properties of three components: A, which provides chemical and heat resistance and a certain surface hardness; B, which imparts high elasticity and toughness; and S, which provides the processing and molding characteristics of thermoplastics and improves electrical properties. Therefore, ABS plastic is a "tough, hard, and rigid" material that is readily available, has excellent overall performance, is inexpensive, and has a wide range of applications.
[0057] The sealing cover plate 19 is positioned to the left of the movable stator and stroke structure. This cover plate and the outer shell together form a sealed cavity for the compressor refrigerant. Because all components are statically sealed, the compression seal requirements are greatly simplified. A portion of the stator's magnetic field penetrates this physically sealed cover plate, driving the left power rotor to rotate. It should be understood that the entire outer shell can also be made of the same or similar material, allowing the magnetic field to penetrate and thus drive the corresponding rotor to rotate.
[0058] Therefore, this solution takes into account the compressor sealing, compressor load reduction, travel distance limitation, and the feasibility of the overall motor design in addition to the main spirit of the present invention. In addition, through the above description of the embodiment of the present disclosure, the working principle of the compressor assembly can be understood as follows:
[0059] The stroke structure moves the movable stator and stationary scroll a small distance to the right along the axial direction. After this movement is executed (compressor mode), the structures of the motor and compressor cavity change. For the compressor cavity, the originally separated stationary scroll and orbiting scroll are combined. Because the distance between them is reduced, the oil film between the orbiting and stationary scrolls refills the gap, and the various chambers are resealed. The compressor can now rotate normally to compress the gas, and the load on the compressor side is applied.
[0060] For the motor, the axial travel causes the air gap on the left to expand, while the air gap on the right to decrease. The magnetic lines of force on the left escape from the outer stator and are primarily formed through the air gap. As a result, the magnetic resistance of the magnetic circuit increases significantly, and its ability to drive the left rotor decreases. By the same token, because the air gap on the right is compressed, the right rotor can operate at full power. The movable stator, the compressor-side rotor, and the compressor-side stator together form a complete axial magnetic flux disc motor. Because of its mechanical structure, this motor is connected to the compressor's movable scroll. At this time, the full power is output to the scroll through the right rotor, completing the compressor's primary function.
[0061] When the stroke structure causes the movable stator to move to the left, the static scroll and the movable scroll will separate again. Because of this separation, the scroll chambers will be reconnected, and the compressor's compressed gas load will be removed because the chambers are connected. At this time, the load on the entire compressor side is only some mechanical friction torque. At this time, the air gap on the right side of the disc motor will become larger, and the air gap on the left side will become smaller. The movable stator, the power output rotor, and the power output side stator together constitute another complete axial magnetic flux disc motor, and its power will be output outward along the output shaft of the left output rotor.
[0062] It should be understood that the compressor assembly of the present invention may be installed in a variety of vehicles, including cars, trucks, buses, hybrid vehicles, pure electric vehicles, and the like. Therefore, the subject matter of the present invention is also intended to protect various vehicles equipped with the compressor assembly of the present invention. For example, the compressor assembly may be installed in the electric drive system of a vehicle.
[0063] In summary, the core principle of this invention is to design an axially variable mechanical structure within the motor, allowing a portion of the motor to move axially. This change in the motor structure alters the entire motor's magnetic circuit, resulting in different operating modes. In each operating mode, the motor operates in a state of either driving the compressor or outputting power, achieving a power distribution effect.
[0064] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the legal protection scope of the present invention.
