Description

Technical Field

[0001] This invention relates to a compressor with movable eccentric flexible force compensation function, and particularly to a compressor with movable eccentric flexible force compensation function. Background Technology

[0002] Existing scroll compressors include a fixed scroll component with involute blades and a moving scroll component with involute blades that cooperates with the fixed scroll component. The moving scroll component and the fixed scroll component work together to form multiple compression chambers with variable volumes. Power drives the moving scroll component to revolve along its orbital path, thereby completing the intake, compression, and discharge of gas. Preventing the self-rotation of the moving scroll component is a crucial technology for scroll compressors to achieve compression. Existing scroll compressors use cross rings, rigid cylindrical shafts, spherical couplings, etc., to achieve this. However, this results in direct rigid contact between components in the radial direction, making them susceptible to damage from accidental impacts during abnormal operation. Improving reliability is essential.

[0003] Existing relevant patent applications include:

[0004] Invention patent CN116025563A involves installing a spring device in the axial direction of a cylindrical pin to adjust the axial direction of the structure, thereby solving the problem of adjusting the tooth tip clearance and reducing leakage, vibration, and noise. However, this patent does not address the radial direction, which is more susceptible to impact and damage, and lacks corresponding measures to address leakage, vibration, and noise issues in the radial direction, thus failing to improve the compressor's operational reliability.

[0005] The anti-rotation pin and anti-rotation ring described in utility model CN221033099U are both composite layer structures made of highly elastic materials such as PTFE, PEEK, and PVC. They aim to reduce noise and vibration caused by collisions between the anti-rotation ring and pin, primarily for noise reduction. This addresses the noise and vibration generated by contact and collisions between components during normal operation, but it does not address damage from accidental impacts during abnormal operation, and therefore does not improve the reliability of the compressor. Because the compressor generates significant gas force during operation, the gaps between components tend to increase. However, the use of highly elastic materials cannot compensate for these gaps, leading to increased leakage and decreased compressor efficiency.

[0006] In view of the problems existing in the above-mentioned existing technologies, it is necessary to research and design a new type of compressor with movable eccentric flexible force compensation function to overcome the problems existing in the existing technologies. Summary of the Invention

[0007] To address the technical problem of direct rigid contact between components in the radial direction, which makes them prone to collision damage during abnormal operation due to accidental impact, a compressor with movable eccentric flexible force compensation function is provided.

[0008] The technical means employed in this invention are as follows:

[0009] A compressor with movable eccentric flexible force compensation function includes: a fixed scroll component, a moving scroll component, and a support component; the moving scroll component is assembled with the fixed scroll component in a relative fit, and the support component supports the moving scroll component.

[0010] Furthermore, a rotation device is provided between the moving vortex component and the supporting component;

[0011] Furthermore, the rotation device includes: a rigid shaft component;

[0012] Furthermore, one end of the rigid shaft component is fixedly installed in the rigid shaft hole on the moving scroll component or the support component, and the other end is inserted into the limiting groove on the support component or the moving scroll component;

[0013] Furthermore, a semi-rigid component, either a full circle or a semi-arc, is provided inside the side wall of the limiting groove;

[0014] Furthermore, the semi-rigid component is one of the semi-rigid components, namely, a leaf spring or a corrugated spring;

[0015] Furthermore,

[0016] The minimum elastic force of a semi-rigid component is F. 弹min， The maximum elastic force is F 弹max ;

[0017] The maximum force on the rigid shaft when the compressor is working normally is F. 轴max ;

[0018] When the compressor is working normally, F 轴max ≤F 弹min ;

[0019] When the compressor is subjected to an impact destructive force, the rigid shaft experiences a force F. 轴异常 ,

[0020] When the compressor is subjected to impact damage force F 弹max ≥F 轴异常 ≥F 弹min ;

[0021] Furthermore, the rigid shaft component and the semi-rigid component come into contact with the sidewall of the limiting groove and the semi-rigid component.

[0022] Furthermore, the number of rigid shaft holes is at least two, which are either rigid shaft holes C provided on the moving scroll component or rigid shaft holes D provided on the support component, for fixing the rigid shaft component.

[0023] Furthermore, the number of limiting grooves is the same as the number of rigid shaft holes, and is either a limiting groove A provided on the moving scroll component or a limiting groove B provided on the support component, used for limiting the rigid shaft component after insertion;

[0024] Furthermore, the limiting groove A is arranged opposite to and used in conjunction with the rigid shaft hole D;

[0025] Furthermore, the limiting groove B is arranged opposite to and used in conjunction with the rigid shaft hole C.

[0026] Furthermore, the semi-rigid component is installed in limiting groove A and limiting groove B;

[0027] Furthermore, the number of semi-rigid components assembled in the limiting groove A and the limiting groove B is at least one.

[0028] The working steps of this invention include: the fixed scroll component and the moving scroll component mesh with each other, the refrigerant is compressed in the compression chamber, the moving scroll component performs translational motion and has a tendency to rotate on its own, an anti-rotation device is used to prevent the moving scroll component from rotating on its own, and a movable eccentric flexible force compensation mechanism is added to the anti-rotation device. When the moving scroll component is subjected to an increased impact destructive force, the movable eccentric flexible force compensation mechanism can yield and unload the impact destructive force, and during normal operation, the movable eccentric flexible force compensation mechanism provides a certain elastic thrust, so that the moving scroll component and the fixed scroll component fit more tightly.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. The compressor with movable eccentric flexible force compensation function provided by this invention has a fixed scroll component and a moving scroll component that mesh with each other. The refrigerant is compressed in the compression chamber, and the moving scroll component performs translational motion with a tendency to rotate. An anti-rotation device is used to prevent the moving scroll component from rotating. Simultaneously, a movable eccentric flexible force compensation mechanism is added to the anti-rotation device. When the moving scroll component is subjected to liquid impact or abnormal increase in refrigerant pressure, especially in the radial direction, the moving scroll component will be subjected to an impact force far greater than that under normal operation. If this force exceeds the component's strength, the component will break and be damaged. This invention aims to solve the above-mentioned problems. The movable eccentric flexible force compensation mechanism of this invention can displace and unload the impact force in the radial direction, thus protecting the scroll component and improving the reliability of the compressor.

[0031] 2. The compressor with movable eccentric flexible force compensation function provided by this invention features a fixed scroll component and a moving scroll component that mesh with each other. The refrigerant is compressed within the compression chamber. The moving scroll component undergoes translational motion and has a tendency to rotate. An anti-rotation device prevents the moving scroll component from rotating. Simultaneously, a movable eccentric flexible force compensation mechanism is incorporated into the anti-rotation device. During normal operation, this mechanism provides sufficient elastic thrust, ensuring a tighter fit between the moving and fixed scroll components, reducing leakage in the compression chamber and improving compressor efficiency. This structure not only unloads impact forces and protects the scroll component during abnormal operation in the radial direction, but also ensures a tighter fit between components during normal operation, reducing leakage and improving compressor efficiency.

[0032] In summary, the technical solution of this invention solves the problem in the prior art where components are directly in rigid contact in the radial direction, making them susceptible to collision damage under accidental impact forces during abnormal operation, thus improving reliability.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0047] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0049] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0050] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0051] like Figure 1 As shown, the present invention provides a compressor with movable eccentric flexible force compensation function, including: a fixed scroll component 100, a moving scroll component 200, and a support component 300; the moving scroll component 200 is assembled with the fixed scroll component 100 in a relative fit, and the support component 300 supports the moving scroll component 200.

[0052] A rotation device is provided between the moving vortex component 200 and the support component 300; the rotation device includes: a rigid shaft component 500; one end of the rigid shaft component 500 is fixedly installed in a rigid shaft hole on the moving vortex component 200 or the support component 300, and the other end is inserted into a limiting groove on the support component 300 or the moving vortex component 200; a semi-rigid component 400 is provided in the limiting groove; the rigid shaft component 500 and the semi-rigid component 400 are in contact with the side wall of the limiting groove and the semi-rigid component 400, and the semi-rigid component undergoes elastic deformation under a certain impact destructive force.

[0053] The number of rigid shaft holes is at least two, which are either rigid shaft holes C202 provided on the moving scroll component 200 or rigid shaft holes D302 provided on the support component 300, for fixing the rigid shaft component 500.

[0054] The number of limiting grooves is the same as the number of rigid shaft holes. One type is the limiting groove A201 set on the moving scroll component 200 or the limiting groove B301 set on the support component 300, which is used for limiting the rigid shaft component 500 after insertion. The limiting groove A201 is arranged opposite to the rigid shaft hole D302 and used in cooperation. The limiting groove B301 is arranged opposite to the rigid shaft hole C202 and used in cooperation.

[0055] The semi-rigid component 400 is installed in the limiting groove A201 and the limiting groove B301; the semi-rigid component 400 is an elastic component, either a leaf spring or a corrugated spring; the semi-rigid component 400 is either a full circle or a semi-arc.

[0056] The number of semi-rigid components 400 assembled in the limiting grooves A201 and B301 is at least one.

[0057] The present invention, employing the above technical solution, can prevent the moving scroll component from self-rotating. When the impact and destructive force in the scroll compression chamber increases and is transmitted to the rigid shaft component, it is then transmitted to the semi-rigid component. The semi-rigid component unloads the impact and destructive force through elastic deformation, preventing damage to the scroll component and improving the reliability of the compressor. At the same time, during normal operation, the semi-rigid component can provide a certain elastic thrust to the moving scroll component, making the moving scroll component and the fixed scroll component fit more tightly, reducing leakage in the compression chamber and improving the compressor efficiency.
