Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] Reference below Figure 1-Figure 3 The compression assembly 100 of the compressor according to the embodiment of the utility model is described. The vane spring 4 of the compression assembly 100 is installed and limited by the limiting structure 5 pressed into the cylinder 1, which can ensure the installation stability of the vane spring 4 and prevent the vane spring 4 from automatically falling out, thereby reducing the risk of vane noise.

[0037] like Figure 1-Figure 3As shown, a compression assembly 100 of a compressor according to one embodiment of the present invention includes a cylinder 1, a crankshaft 2, a piston 6, a vane 3, a limiting structure 5, and a vane spring 4. A cam portion 21 is formed on the crankshaft 2. The cam portion 21 can push the piston 6, so that the piston 6 can push the vane 3 to move, causing the vane 3 to reciprocate within the vane groove 11, thereby facilitating the compression and discharge of gas.

[0038] The cylinder 1 is provided with a vane slot 11 and a mounting hole 12. The vane slot 11 extends radially of the cylinder 1. The mounting hole 12 is located outside the vane slot 11 and communicates with the vane slot 11. The mounting hole 12 can be configured to be open outward to facilitate installation of the limiting structure 5 into the mounting hole 12 from outside the mounting hole 12.

[0039] The piston 6 is installed in the cylinder 1, and the vane 3 is installed in the vane groove 11. The vane 3 is located on the outside of the piston 6, and the vane 3 can reciprocate in the vane groove 11. When the crankshaft 2 rotates, it drives the piston 6 to reciprocate to compress the refrigerant. At the same time, the piston 6 pushes the vane 3 to reciprocate radially in the vane groove 11. Therefore, the crankshaft 2 can push the slide 3 to reciprocate in the radial direction of the cylinder 1 during rotation, and the mounting hole 12 can be provided at the outer end of the slide groove 11. In this way, during actual installation, the slide 3 can be installed from the mounting hole 12 into the slide groove 11 to press and contact the outer peripheral wall of the crankshaft 2. When the slide spring 4 is extended into the slide groove 11 and installed to the mounting hole 12 through the limiting structure 5, the slide spring 4 is pressed so that the slide spring 4 is pressed between the outer end of the slide 3 and the limiting structure 5. In this way, when the slide 3 reciprocates with the rotation of the crankshaft 2, the slide spring 4 can be continuously compressed and extended to always apply an elastic preload to the slide 3, thereby ensuring that the inner end of the slide 3 can stably and effectively contact the outer peripheral wall of the crankshaft 2.

[0040] Among them, the limiting structure 5 is pressed into the mounting hole 12, and the slide spring 4 is elastically pressed between the limiting structure 5 and the slide 3. The press-fitting friction between the limiting structure 5 and the inner wall of the mounting hole 12 is greater than the pressure exerted on the slide spring 4 when the slide 3 moves to the outermost position in the slide groove 11. That is to say, when the force exerted by the slide 3 on the limiting structure 5 is the largest during the reciprocating motion, the elastic force exerted on the limiting structure 5 by the slide spring 4 is less than the press-fitting friction between the limiting structure 5 and the inner wall of the mounting hole 12, so that the limiting structure 5 can play a good limiting role on the slide spring 4, preventing the slide 3 and the slide spring 4 from falling off from the cylinder 1.

[0041] In addition, the limiting structure 5 is set to be press-fitted with the mounting hole 12, and the press-fitting force of the two can be used to fix the position of the limiting structure 5, without the need for a complicated design of the limiting structure 5, such as the need for installation through traditional threaded connection, which simplifies the installation steps; and after long-term use, there is no possibility of loosening of the threads as in the threaded connection method, which greatly improves the stability of the limiting structure 5, thereby ensuring that the slide 3 is stably in the slide groove 11, and ensuring that the slide spring 4 stably applies elastic force to the slide 3 to prevent the generation of slide noise.

[0042] According to the compression assembly 100 of the compressor of the embodiment of the present invention, by providing a limiting structure 5 that is press-fitted with the cylinder 1, the slide spring 4 can be stably and effectively limited, preventing the slide 3 and the slide spring 4 from detaching from the cylinder 1, thereby improving the stability of the slide 3, and the installation method of the limiting structure 5 is simple, which is conducive to quick installation and reduces installation costs.

[0043] In some embodiments, the limiting structure 5 includes a connected necking section and a limiting fitting section. The limiting structure 5 is suitable for being inserted into the mounting hole 12 along the necking section and being limited in the mounting hole 12 by the limiting fitting section. The outer diameter of the necking section is smaller than the inner diameter of the mounting hole 12, and the outer diameter of the limiting fitting section is larger than the outer diameter of the necking section. By utilizing the necking section and the limiting fitting section to cooperate with the mounting hole 12, both rapid installation guidance and limiting locking can be achieved.

[0044] Therefore, when the limiting structure 5 is installed in the mounting hole 12, the necking section of the limiting structure 5 can be aligned with the open end of the mounting hole 12, so that the limiting structure 5 is first inserted into the mounting hole 12 at the necking section. The outer diameter of the necking section is smaller and can quickly enter the mounting hole 12, which is conducive to improving installation efficiency and saving installation time. As the necking section goes deeper into the mounting hole 12, the limiting fitting section can use its larger outer diameter to press and contact the inner wall of the mounting hole 12, so that the limiting structure 5 is limited and locked in the mounting hole 12 to achieve installation fit.

[0045] Specifically, if Figure 2 As shown, the left end portion of the limiting structure 5 can be constructed as a necked section so that the left end of the limiting structure 5 can quickly extend into the mounting hole 12. At the same time, the middle portion of the limiting structure 5 is constructed as a limiting fitting section so that after the limiting fitting section extends into the mounting hole 12, it can be stably locked and retained in the mounting hole 12 to prevent the generation of sliding sound. The structure is simple and the installation is convenient.

[0046] In some embodiments, the outer diameter of the necking section is configured to gradually increase from the end away from the limiting fitting portion to the end connected to the limiting fitting portion. In other words, the outer diameter of the necking section is gradually changed, and is specifically configured to gradually increase from the end away from the limiting fitting portion to the end connected to the limiting fitting portion. Figure 2 As shown, the outer diameter of the necking section is set to gradually increase from left to right.

[0047] Therefore, when assembling the limiting structure 5 and the mounting hole 12, the part with a smaller outer diameter of the necking section is easier to install into the mounting hole 12, that is, the left end of the necking section can be quickly installed into the mounting hole 12, and under the guiding action of the outer wall of the necking section, the fit with the inner wall of the mounting hole 12 becomes tighter and tighter, until the limiting fitting section is pressed against the inner peripheral wall of the mounting hole 12 to achieve locking and fixation. Therefore, the provision of the necking section is not only conducive to quick installation, but also can achieve guided fit with the mounting hole 12 to achieve a gradually tight installation effect.

[0048] In some embodiments, the inner wall of the mounting hole 12 that cooperates with the limiting structure 5 is constructed as an inclined wall, and the inner diameter of the inclined wall gradually decreases along the radial direction of the cylinder 1 to be press-fitted with the limiting structure 5, that is, the inner diameter of the inner wall of the mounting hole 12 can be set to be gradual, that is, the inner wall of the mounting hole 12 can be set to be inclined along the axial direction of the mounting hole 12, such as Figure 1 As shown in , the inner diameter of the inner wall of the mounting hole 12 can be set to gradually decrease from left to right, that is, the inner wall of the mounting hole 12 is inclined from left to right toward the direction close to the axis of the mounting hole 12.

[0049] In this way, after the limiting structure 5 is pressed in from the outside of the mounting hole 12, the outer peripheral wall of the limiting structure 5 can be limited and matched with the inner wall of the mounting hole 12, and the limiting structure 5 can be maintained in the mounting hole 12 under the limiting action of the inner wall of the mounting hole 12. The closer the limiting structure 5 is to the open end of the mounting hole 12, the greater the force it is subjected to from the inner wall of the mounting hole 12, and it is less likely to fall off, which is beneficial to improving the installation stability of the limiting structure 5.

[0050] In some embodiments, the limiting structure 5 includes a limiting plate portion 51 and an elastic pressing portion 52. The elastic pressing portion 52 is bent and connected to the limiting plate portion 51. One end of the sliding spring 4 is elastically pressed against the limiting plate portion 51. The elastic pressing portion 52 is pressed tightly against the inner wall of the mounting hole 12. Thus, the limiting structure 5 and the inner wall of the mounting hole 12 can be pressed and fixed, and effective limitation of the sliding spring 4 can also be achieved.

[0051] Specifically, the limiting plate portion 51 and the elastic pressing portion 52 can be integrally formed, and the limiting plate portion 51 and the elastic pressing portion 52 are connected at a certain bending angle, such as the angle between the elastic pressing portion 52 and the limiting plate portion 51 is greater than 90 degrees. During installation, the elastic pressing portion 52 can be extended into the mounting hole 12 along the opening direction of the mounting hole 12. At the same time, the limiting plate portion 51 and the opening direction of the mounting hole 12 can be perpendicularly arranged so that one end of the slide spring 4 presses against the side surface of the limiting plate portion 51 facing the mounting hole 12. At this time, the elastic pressing portion 52 is bent relative to the limiting plate portion 51 and tilted radially outwardly along the mounting hole 12. When the elastic pressing portion 52 contacts the inner wall of the mounting hole 12, the elastic pressing portion 52 can apply a radially outward elastic pressing force toward the inner wall of the mounting hole 12, thereby achieving stable contact between the elastic pressing portion 52 and the cylinder 1.

[0052] The elastic pressing portion 52 can be bent on the side of the limiting plate portion 51 facing the sliding spring 4 or on the side of the limiting plate portion 51 away from the sliding spring 4 . The arrangement is flexible and optional.

[0053] like Figure 2 As shown, the elastic pressing portion 52 is bent on the side of the limiting plate portion 51 toward the sliding spring 4, so that the elastic pressing portion 52 is located on the outside of one end of the sliding spring 4, so that the elastic pressing portion 52 can play a role of radial limitation and axial guidance on the end of the sliding spring 4, thereby preventing the sliding spring 4 from bending significantly in the radial direction during the expansion and contraction process, ensuring the reliability of the installation of the sliding spring 4, and ensuring that an effective elastic force is applied to the slide 3.

[0054] In some embodiments, the elastic pressing portion 52 is constructed as a spring and includes a first sub-piece 521 and a second sub-piece 522. The first sub-piece 521 is bent and connected to the limiting plate portion 51, and the second sub-piece 522 is bent and connected to the side of the first sub-piece 521 away from the limiting plate portion 51, and the connection between the first sub-piece 521 and the second sub-piece 522 is pressed tightly against the inner wall of the mounting hole 12. That is, the elastic pressing portion 52 is constructed as a long strip and includes two parts that are bent and connected. Figure 3 As shown, the first sub-piece 521 is connected to the edge of the limiting plate portion 51 and is bent relative to the limiting plate portion 51, and the second sub-piece 522 is connected to the first sub-piece 521 and is bent to form a certain angle with each other, and as shown Figure 3 As shown, the second sub-piece 522 is bent and tilted toward the center of the mounting hole 12 compared to the first sub-piece 521 .

[0055] Therefore, when the limiting structure 5 is installed in the mounting hole 12, the second sub-piece 522 is axially inclined compared to the mounting hole 12, so that the distance between the free ends of the second sub-piece 522 of the two relatively distributed elastic pressing parts 52 is smaller than the inner diameter of the mounting hole 12, and then after the second sub-piece 522 enters the mounting hole 12, the outer side surface of the second sub-piece 522 can be formed into a guide surface, so that the elastic pressing part 52 gradually penetrates into the mounting hole 12 along the guide surface, and when the connection between the first sub-piece 521 and the second sub-piece 522 is pressed and in contact with the inner wall of the mounting hole 12, the pressing force between the limiting structure 5 and the inner wall of the mounting hole 12 reaches the maximum. At this time, the limiting structure 5 can be further pushed into the mounting hole 12 to the deepest point, ensuring that the limiting structure 5 is stably installed in the mounting hole 12 and the fitting depth is large, thereby preventing the limiting structure 5 from falling out of the mounting hole 12.

[0056] In this way, by configuring the elastic pressing portion 52 as a first sub-piece 521 and a second sub-piece 522 that are bent and connected, it is convenient to quickly press-fit the limiting structure 5 into the mounting hole 12, thereby improving the mounting efficiency.

[0057] In some embodiments, the width of the second sub-piece 522 is configured to gradually decrease in a direction away from the first sub-piece 521, so that the second sub-piece 522 forms a tip with a smaller width at one end away from the first sub-piece 521. Figure 3 As shown, the second sub-piece 522 is constructed in a triangular shape, with the base of the triangle connected to the first sub-piece 521 , and the vertex of the triangle serving as the tip of the second sub-piece 522 .

[0058] Therefore, when the limiting structure 5 is installed in the mounting hole 12, the tip of the second sub-piece 522 can enter the mounting hole 12 first. At this time, the tip width of the second sub-piece 522 is relatively small, and will not form a stop with the end edge of the mounting hole 12. A small force can be applied to make the tip of the second sub-piece 522 quickly enter the mounting hole 12, and under the guidance of the guide surface, it can be deepened, so that the limiting structure 5 can be quickly pressed and installed, saving installation time.

[0059] In some embodiments, the angle between the first sub-piece 521 and the limiting plate portion 51 is greater than 90°, such as setting the angle between the two to 113°, 122°, 134°, 143°, 159°, or 161°, that is, the first sub-piece 521 is inclined relative to the inner wall of the mounting hole 12, so that the first sub-piece 521 can elastically deform inward after contacting the inner wall of the mounting hole 12, thereby achieving effective pressure between the limiting structure 5 and the inner circumferential wall of the mounting hole 12; and the angle between the first sub-piece 521 and the second sub-piece 522 is greater than 90° and less than 180°, such as setting the angle between the two to 110°, 121°, 133°, 145°, 158°, 161°, or 172°, so that the connection between the first sub-piece 521 and the second sub-piece 522 is relatively smooth, thereby achieving effective contact with the inner wall of the mounting hole 12.

[0060] In actual design, the first sub-piece 521 can be set at an angle greater than 90° with the limiting plate portion 51, and the second sub-piece 522 can be set perpendicular to the limiting plate portion 51, so that after the first sub-piece 521 is tilted outward relative to the limiting plate portion 51, it can achieve a press fit with the inner wall of the mounting hole 12 at the position connected to the second sub-piece 522. Therefore, setting the above angle range can enable the second sub-piece 522 to be quickly guided in the mounting hole 12 and achieve stable press installation of the limiting structure 5.

[0061] In some embodiments, there are multiple elastic pressing portions 52, and the multiple elastic pressing portions 52 are spaced apart and distributed circumferentially around the limiting plate portion 51. In this way, the multiple elastic pressing portions 52 can be simultaneously press-fitted and fixed to the inner wall of the mounting hole 12, thereby improving the press-fitting stability of the limiting structure 5 and the cylinder 1.

[0062] Specifically, if Figure 3 As shown, the elastic pressing portions 52 can be set to 4, and the 4 elastic pressing portions 52 are spaced apart and distributed in the circumferential direction of the limiting plate portion 51, and the spacing between the 4 elastic pressing portions 52 is uniform, that is, the distribution angle of two adjacent elastic pressing portions 52 in the circumferential direction is 90 degrees. Therefore, when the limiting structure 5 is pressed into the mounting hole 12, the 4 elastic pressing portions 52 can be press-fitted with the inner wall of the mounting hole 12 at four positions in the circumferential direction, thereby ensuring the reliability of the press-fitting.

[0063] Among them, the multiple elastic pressing parts 52 are all bent and connected to the same side of the limiting plate part 51, such as Figure 3 As shown, the four elastic pressing portions 52 define a limiting space 53 on the upper side of the limiting plate portion 51, so that the end of the sliding plate spring 4 away from the sliding plate 3 extends into the limiting space 53, so that the four elastic pressing portions 52 can radially limit the sliding plate spring 4 from multiple positions in the circumferential direction, making it less likely for the sliding plate spring 4 to undergo radial bending deformation and the structure more stable.

[0064] At the same time, if Figure 2 As shown, a limiting groove 31 is provided at the end of the slide 3, and the end of the slide spring 4 away from the limiting structure 5 extends into the limiting groove 31 to limit the slide spring 4 through the limiting groove 31. As a result, both ends of the slide spring 4 can achieve radial limitation, ensuring that the slide spring 4 can stably extend or compress along the axial direction.

[0065] As well as Figure 2 As shown, among the multiple elastic pressing parts 52, the angle between the first sub-piece 521 of each elastic pressing part 52 and the limiting plate part 51 is greater than 90°, so that the angle with the limiting plate part 51 is greater than 90° compared to the axial inclination of the mounting hole 12, and at the same time, the angle between the first sub-piece 521 and the second sub-piece 522 is greater than 90° and less than 180°, so that the second sub-piece 522 is inclined toward the direction close to the inner axis of the mounting hole 12 compared to the first sub-piece 521. With such a design, the second sub-pieces 522 of the multiple elastic pressing parts 52 can be jointly constructed as a necking section, and the connection between the second sub-piece 522 and the first sub-piece 521 can be constructed as a limiting matching section, that is, the limiting structure 5 can be quickly installed into the mounting hole 12 under the guiding action of the second sub-piece 522, and locked and fixed at the connection between the second sub-piece 522 and the first sub-piece 521. The structure is simple and the installation is convenient.

[0066] In some embodiments, the elastic pressing portions 52 are arranged in multiple groups, and the multiple groups of elastic pressing portions 52 are distributed circumferentially of the limiting plate portion 51, so that the multiple groups of elastic pressing portions 52 are respectively pressed onto the inner wall of the mounting hole 12 in the circumferential direction of the limiting plate portion 51, thereby improving the press-fitting reliability.

[0067] Among them, there are two elastic pressing parts 52 in each group, and the two elastic pressing parts 52 are relatively distributed in the radial direction of the mounting hole 12. Therefore, the two elastic pressing parts 52 in each group are arranged to be distributed opposite to each other in the radial direction of the mounting hole 12, so that the two elastic pressing parts 52 and the inner wall of the mounting hole 12 have opposite directions of force. Moreover, through the circumferential arrangement of multiple groups, the inner wall of the mounting hole 12 can press the limiting structure 5 at multiple positions in the circumferential direction toward the middle, thereby exponentially increasing the pressing force between the inner wall of the mounting hole 12 and the limiting structure 5, increasing the press-fit friction force of the limiting structure 5, preventing the sliding spring 4 from pushing the limiting structure 5 out of the mounting hole 12, and ensuring the stable installation of the limiting structure 5.

[0068] In some embodiments, the limiting structure 5 also includes an arc-shaped transition section 54, which is connected between the limiting plate portion 51 and the elastic pressure portion 52, wherein the arc-shaped transition section 54 is constructed as an arc-shaped structure to achieve a smooth transition between the limiting plate portion 51 and the elastic pressure portion 52 through the arc-shaped transition section 54.

[0069] like Figure 3As shown, arc-shaped transition sections 54 are provided at the connection between the limiting plate portion 51 and the multiple elastic pressing portions 52. Thus, by providing the arc-shaped transition sections 54, the structural stress at the connection between the limiting plate portion 51 and the elastic pressing portions 52 can be reduced, thereby avoiding structural fracture at the connection. At the same time, when the elastic pressing portions 52 are subjected to greater force, they can bend and deform at the arc-shaped transition sections 54 and generate a certain elastic force, thereby enhancing the contact effect between the elastic pressing portions 52 and the inner wall of the mounting hole 12.

[0070] In some embodiments, at least a portion of the limit plate portion 51 extends from one end of the mounting hole 12 away from the slide slot 11, wherein the end of the mounting hole 12 away from the slide slot 11 is an open end, that is, the mounting hole 12 is open toward the outside of the cylinder 1. Extending at least a portion of the limit plate portion 51 from the mounting hole 12 out of the cylinder 1 allows the operator to clamp the limit structure 5 from the limit plate portion 51 when replacing the internal structural parts of the cylinder 1, so as to overcome the friction between the limit structure 5 and the inner wall of the mounting hole 12 and disassemble the limit structure 5, thereby facilitating the replacement and installation of the internal structural parts and convenient operation.

[0071] In some embodiments, the cylinder 1, the piston 6 and the vane 3 may be provided in multiple groups so as to be spaced apart in the axial direction of the crankshaft 2, such as Figure 1 and Figure 2 As shown in FIG, the cylinder 1, the piston 6 and the sliding plate 3 are arranged in two groups, and the sliding plate spring 4 of each group is correspondingly provided with a limiting structure 5.

[0072] The utility model also provides a compressor.

[0073] A compressor according to an embodiment of the present invention includes a crankshaft 2 and a compression assembly 100 of any of the above-described compressor embodiments, wherein the crankshaft 2 is used to drive a vane 3 to reciprocate within a vane slot 11. By providing the above-described compression assembly 100 and a limiting structure 5 press-fitted with the cylinder 1, the compressor can stably and effectively limit the position of the vane spring 4, preventing the vane 3 and the vane spring 4 from detaching from the cylinder 1, thereby improving the stability of the vane 3. Furthermore, the limiting structure 5 is simple to install, facilitating quick installation and reducing installation costs.

[0074] Among them, the setting of the compression assembly 100 can ensure the stable position of the slide 3 and the slide spring 4, thereby ensuring that the slide 3 can stably reciprocate under the action of the crankshaft 2, ensuring the reliable stroke of the slide 3, and being able to achieve accurate compression and exhaust, thereby improving the operating reliability of the compressor and ensuring the work efficiency of the compressor.

[0075] The utility model also provides an air conditioner.

[0076] According to an embodiment of the present invention, an air conditioner including the compressor of the above-described embodiment is provided with a limiting structure 5 press-fitted with the cylinder 1, thereby stably limiting the position of the vane 3 and the vane spring 4, improving the reliability of the vane 3. The structure is simple and easy to install, which helps ensure stable operation of the compressor. As a result, the compressor in the air conditioner can continuously and stably cool or heat, thereby meeting the user's usage needs and improving the user experience.

[0077] The utility model also provides a vehicle.

[0078] A vehicle according to an embodiment of the present invention includes the compressor or air conditioner of the aforementioned embodiment. By providing a limiting structure 5 press-fitted with the cylinder 1, the sliding vane 3 and the sliding vane spring 4 can be stably limited, thereby improving the reliability of the sliding vane 3. The simple structure and easy installation facilitate stable operation of the compressor. This allows the compressor in the air conditioner to continuously and stably cool or heat, thereby meeting user needs and improving the user experience.

[0079] Therefore, during the cooling or heating process inside the vehicle, the sliding vane 3 can operate reliably for a long time, ensuring the cooling or heating effect of the compressor and achieving effective regulation of the temperature inside the vehicle.
