[0096] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0097] According to the first aspect of the present application, reference Figure 1 and Figure 2 , a connecting rod device 100 is provided, including: a rotating shaft 110, a first type of mounting member 120 and a second type of mounting member 140.

[0098] The rotating shaft 110 in the embodiment of the present application has a central axis 110 a , the first type of mounting member 120 is used to mount the first type of connecting rod 130 , and the second type of mounting member 140 is used to mount the second type of connecting rod 150 which is different from the first type of connecting rod 130 .

[0099] The first type of mounting member 120 and the second type of mounting member 140 are located at different axial positions of the rotating shaft 110 , so that the projection of the first type of connecting rod 130 on the central axis 110 a overlaps with the projection of the second type of connecting rod 150 on the central axis 110 a .

[0100] Through the above technical scheme, the first type of connecting rod 130 and the second type of connecting rod 150 can be installed on the rotating shaft 110 through different mounting parts, and the projection of the first type of connecting rod 130 on the central axis 110a is overlapped with the projection of the second type of connecting rod 150 on the central axis 110a, so that when the two types of connecting rods are in the same compression state, they can generate force interaction with different mounting parts, thereby avoiding the force interaction between the same mounting part and different connecting rods, alleviating the wear between the connecting rod and the mounting part, and effectively maintaining the stroke of each type of connecting rod to ensure that the compression efficiency is not reduced.

[0101] The connecting rod device 100 of the present application can be applied to a star-shaped air compressor having more than or equal to two cylinders.

[0102] It can be understood that the projection of the first type of mounting component 120 on the central axis 110a in the embodiment of the present application is located within the projection of the second type of mounting component 140 on the central axis 110a, so that the projection light of the first type of connecting rod 130 on the central axis 110a overlaps with the projection of the second type of connecting rod 150 on the central axis 110a.

[0103] In some embodiments, a projection of the first type of connecting rod 130 on the central axis 110 a completely overlaps or partially overlaps with a projection of the second type of connecting rod 150 on the central axis 110 a .

[0104] By completely or partially overlapping the projection of the first type connecting rod 130 on the central axis 110a with the projection of the second type connecting rod 150 on the central axis 110a, the connecting rod device 100 can be made more compact in the axial direction, further reducing the space volume occupied by the connecting rod device 100 in the axial direction.

[0105] The projection of the first type of connecting rod 130 on the central axis 110a completely overlaps with the projection of the second type of connecting rod 150 on the central axis 110a, which can ensure that the forces on the connecting rods are on the same horizontal plane, without generating additional shear force on the rotating shaft 110, thereby reducing the deformation of the rotating shaft 110.

[0106] In some embodiments, reference Figure 1 , around the central axis 110a, the first type of connecting rods 130 and the second type of connecting rods 150 are alternately arranged.

[0107] By alternately arranging the first type of connecting rod 130 and the second type of connecting rod 150 around the central axis 110a, it is possible to avoid excessive concentration of the force generated between the same mounting part of the connecting rod device 100 and one type of connecting rod, thereby ensuring uniform force on the connecting rod device 100 and thus ensuring stable operation of the connecting rod device 100.

[0108] In some embodiments, along a projection plane perpendicular to the central axis 110 a , a projection of the first type of connecting rod 130 and a projection of the second type of connecting rod 150 are staggered.

[0109] By staggering the projection of the first type of connecting rod 130 and the projection of the second type of connecting rod 150 on the projection plane perpendicular to the central axis 110a, the arrangement of the connecting rod device 100 is made more reasonable.

[0110] In some embodiments, reference Figure 3 and Figure 4 The first type of connecting rod 130 includes: a first type of connecting portion 131 .

[0111] The first type connection portion 131 is used to form a sliding connection with the first type installation component 120 , wherein at least a portion of the first type connection portion 131 surrounds the first type installation component 120 .

[0112] By utilizing the first-type connecting portion 131 and at least partially surrounding the first-type mounting member 120 to form a sliding connection, when the connecting rod extends into the air passage of the compressor and performs reciprocating motion, the sliding connection formed by the first-type connecting portion 131 and the first-type mounting member 120 can enable the first-type connecting rod 130 and the first-type mounting member 120 to form a stable sliding motion to ensure the smoothness of the movement.

[0113] In some embodiments, reference Fig.13 The first type connecting rod 130 has: a first accommodating cavity 130a.

[0114] The first accommodating cavity 130 a is used to accommodate at least part of the first type of mounting member 120 , wherein the inner wall surface of the first accommodating cavity 130 a formed by the first type of connecting rod 130 is used to constitute a first type of connecting portion 131 to form a surface contact with the first type of mounting member 120 .

[0115] By opening a first accommodating cavity 130a on the first type of connecting rod 130, the first accommodating cavity 130a is utilized to accommodate at least a portion of the first type of mounting component 120, and the inner wall surface of the first accommodating cavity 130a formed by the first type of connecting rod 130 forms a surface contact with the first type of mounting component 120, so that the first type of connecting rod 130 can be installed on the first type of mounting component 120, and a surface contact sliding connection is formed between the two, thereby realizing a stable connection between the first type of mounting component 120 and the first type of connecting rod 130.

[0116] Exemplarily, one end of the first type connecting rod 130 is used to connect to the piston, and the other end serves as the first type connecting portion 131 , which can be connected to the first type mounting member 120 .

[0117] refer to Figures 1 to 14 The first type connecting portion 131 surrounds part of the first type mounting member 120 , and part of the first type mounting member 120 is located in the first accommodating cavity 130 a , thereby realizing the connection between the first type connecting rod 130 and the first type mounting member 120 .

[0118] Exemplarily, a groove can be opened on the first type of connecting rod 130, and the groove is configured as a first accommodating cavity 130a, which is used as a first type of connecting part 131. The bottom surface and the wall surface of the groove are in surface contact with the outer wall surface of the first mounting part and the end surface of the shaft, thereby realizing a stable sliding connection between the first type of connecting rod 130 and the first type of mounting part 120.

[0119] In some embodiments, reference Figure 5 , Figure 6 , Fig.12 The second type connecting rod 150 includes: a second type connecting portion 151, and the second type connecting rod 150 also has: a second accommodating cavity 150a.

[0120] The second type connection portion 151 is used to form a sliding connection with the second type installation member 140, and the second accommodating cavity 150a is used to accommodate part of the first type installation member 120;

[0121] The projection of the second type connecting portion 151 on the central axis 110 a and the projection of the inner wall surface of the second accommodating cavity 150 a formed by the second type connecting rod 150 on the central axis 110 a are staggered.

[0122] Through the second type of connecting part 151 of the second type of connecting rod 150, the second type of connecting part 151 is used to form a sliding connection with the second type of mounting member 140, and the second accommodating cavity 150a of the second type of connecting rod 150 can accommodate part of the first type of mounting member 120, thereby achieving the effect of the second type of connecting rod 150 forming a sliding connection with the second type of mounting member 140 through the first type of mounting member 120, and the projection of the second type of connecting part 151 on the central axis 110a and the projection of the inner wall surface of the second accommodating cavity 150a formed by the second type of connecting rod 150 on the central axis 110a are staggered, thereby ensuring that the second type of connecting rod 150 can form a sliding connection with the second mounting member, and the second accommodating cavity 150a does not interfere with the second type of mounting member 140.

[0123] It can be understood that the second accommodating cavity 150 a does not interfere with the second type of mounting member 140 , that is, the second accommodating cavity 150 a only accommodates a portion of the first type of mounting member 120 and is arranged to avoid the second type of mounting member 140 .

[0124] In some embodiments, reference Figure 4 The first type of connection part 131 forms a surface contact with the first type of mounting member 120; the second type of connection part 151 forms a surface contact with the second type of mounting member 140, wherein the contact area between the first type of connection part 131 and the first type of mounting member 120 is the same as the contact area between the second type of connection part 151 and the second type of mounting member 140.

[0125] By setting the contact area between the first-type connecting part 131 and the first-type mounting part 120 to be the same as the contact area between the second-type connecting part 151 and the second-type mounting part 140, the first-type connecting rod 130 and the second-type connecting rod 150 are connected to the corresponding mounting parts in a unified manner, and the contact areas are the same, so that the force transmission between the first-type connecting rod 130 and the second-type connecting rod 150 and the corresponding mounting parts is basically the same, further improving the operating stability of the connecting rod device 100.

[0126] In some embodiments, reference Figure 5 There is a gap f between the inner wall surface of the second accommodating cavity 150a formed by the second type connecting rod 150 and the outer peripheral wall surface of the first type mounting member 120, so that the second type connecting rod 150 can slide relative to the second type mounting member 140 independently of the first type mounting member 120.

[0127] By forming a gap f between the inner wall surface of the second accommodating cavity 150a formed by the second-type connecting rod 150 and the outer peripheral wall surface of the first-type mounting component 120, the second-type connecting rod 150 can be independent of the first-type mounting component 120 and connected to the second-type mounting component 140, so that the second-type connecting rod 150 can only be directly connected to the second-type mounting component 140.

[0128] Exemplarily, a groove can be opened at the position of the second-type connecting rod 150 corresponding to the first-type mounting member 120, and the groove is utilized as the second accommodating chamber 150a, wherein when the second-type connecting rod 150 forms a surface-contact sliding connection with the second-type mounting member 140, there is a gap between the bottom of the groove and the outer peripheral wall surface of the first-type mounting member 120, thereby avoiding lateral sliding movement between the second-type connecting rod 150 and the first-type mounting member 120 during the relative sliding movement of the second-type connecting rod 150 relative to the second-type mounting member 140.

[0129] In some embodiments, reference Figure 4 and Figure 8 There is a gap g between the first type connecting portion 131 and the outer peripheral wall of the second type mounting member 140, so that the first type connecting rod 130 can slide relative to the first type mounting member 120 independently of the second type mounting member 140.

[0130] By providing a gap g between the first-type connecting portion 131 and the outer peripheral wall surface of the second-type mounting component 140, the first-type connecting rod 130 can form a sliding connection with the first-type mounting component 120 independently of the second-type mounting component 140, so that the first-type connecting rod 130 only forms a surface-contact sliding connection with the first-type mounting component 120, and the second-type connecting rod 150 only forms a surface-contact sliding connection with the second-type mounting component 140. This can further improve the overall operating stability of the connecting rod device 100, avoid the situation where the same mounting component and each connecting rod wear at the same time, and the wear of the connecting rod and the mounting component is accelerated due to the same mounting component being subjected to forces in different directions.

[0131] In some embodiments, along a projection plane perpendicular to the central axis 110 a , a projection of the second type of mounting component 140 is located within a projection of the first type of mounting component 120 .

[0132] By locating the projection of the second type of mounting component 140 within the projection of the first type of mounting component 120 along the projection plane perpendicular to the central axis 110a, the first type of connecting rod 130 and the second type of connecting rod 150 are flexibly connected to the first type of mounting component 120 and the second type of mounting component 140 respectively.

[0133] In some embodiments, reference Figure 6 The connecting rod device 100 further includes: an action member 160 .

[0134] The action member 160 is used to limit the movement of the first type of connecting rod 130 and the second type of connecting rod 150 along the central axis 110a, wherein the action member 160 surrounds at least a portion of the rotating shaft 110, and along a projection plane perpendicular to the central axis 110a, the projection of the action member 160 partially overlaps with the projection of the first type of connecting rod 130 and the projection of the second type of connecting rod 150.

[0135] By providing the action member 160 , the movement of the first type connecting rod 130 and the second type connecting rod 150 in the axial direction of the rotating shaft 110 can be limited, thereby further improving the operation stability of the connecting rod device 100 .

[0136] Among them, the action member 160 surrounds at least a portion of the rotating shaft 110, thereby realizing the connection between the action member 160 and the rotating shaft 110. For example, the action member 160 can be sleeved on the rotating shaft 110. After the action member 160 is installed on the rotating shaft 110, it is necessary to overlap the projection of the action member 160 with the projection of the first type of connecting rod 130 and the projection of the second type of connecting rod 150 along the projection plane perpendicular to the central axis 110a, so as to ensure that the action member 160 can limit the axial movement of the first type of connecting rod 130 and the second type of connecting rod 150 in the axial direction.

[0137] Exemplarily, in actual use, the action member 160 can be set on the side of the first type of mounting member 120 away from the second type of mounting member 140, and can form a rotational connection with the rotating shaft 110 around the central axis 110a, and form a fixed connection with the rotating shaft 110 along the central axis 110a, thereby realizing axial limitation of the first type of connecting rod 130 and the second type of connecting rod 150.

[0138] In some embodiments, reference Fig.10 , Fig.11 The action member 160 has an action space 160a.

[0139] The action space 160a is used for part of the first type connecting rod 130 and part of the second type connecting rod 150 to extend into, wherein the first type connecting rod 130 is spaced apart from the inner wall surface forming the action space 160a, and the second type connecting rod 150 forms a surface contact with the inner wall surface forming the action space 160a.

[0140] By extending part of the first type of connecting rod 130 and part of the second type of connecting rod 150 into the action space 160a of the action member 160, the connection between the first type of connecting rod 130 and the second type of connecting rod 150 and the action member 160 is achieved, thereby further improving the limiting effect of the action member 160 on the first type of connecting rod 130 and the second type of connecting rod 150, and avoiding the radial displacement of the first type of connecting rod 130 and the second type of connecting rod 150 along the central axis 110a during rotation, thereby further realizing the stability of the use of the connecting rod device 100.

[0141] For example, reference Fig.11 The action member 160 includes a first arm 161 and a second arm 162 extending axially along the central axis 110a. The circumferential wall surfaces relatively arranged between the first arm 161 and the second arm 162 can define an action space 160a, so that part of the first type of connecting rod 130 and part of the second type of connecting rod 150 can extend into the action space 160a, so as to limit the radial and axial displacement of the first type of connecting rod 130 and the second type of connecting rod 150 on the central axis 110a.

[0142] In some embodiments, reference Figure 6 The connecting rod device 100 also includes: a third type of mounting member 170 .

[0143] The third type of mounting member 170 is used to mount the action member 160 to the rotation shaft 110 , wherein the third type of mounting member 170 is located between the rotation shaft 110 and the action member 160 .

[0144] The action member 160 is mounted to the rotating shaft 110 through the third type mounting member 170, and the third type mounting member 170 is fixedly mounted on the rotating shaft 110, thereby realizing a fixed connection between the rotating shaft 110 and the action member 160, thereby realizing the use of the action member 160 to limit the axial and radial displacement of the first type connecting rod 130 and the second type connecting rod 150 on the central axis 110a.

[0145] Exemplarily, after the first-type connecting rod 130 is mounted on the first-type mounting member 120 , a gap h is also provided between the first-type connecting rod 130 and the third-type mounting member 170 .

[0146] In some embodiments, the center line of the first type of mounting component 120 , the center line of the second type of mounting component 140 , and the center line of the third type of mounting component 170 are collinear with the central axis 110 a of the rotating shaft 110 .

[0147] By arranging the center lines of the first type mounting member 120, the second type mounting member 140 and the third type mounting member 170 colinearly with the central axis 110a of the rotating shaft 110, the rotation speeds of the three are consistent, thereby achieving synchronous rotation of the three.

[0148] In some embodiments, the active member 160 has a central space 160 b extending along the central axis 110 a , wherein at least a portion of the third type mounting member 170 is located in the central space 160 b .

[0149] By locating at least a portion of the third type of mounting member 170 in the central space 160b opened along the central axis 110a of the active member 160, the compactness of the connecting rod device 100 can be further improved to reduce the overall volume occupied by the connecting rod device 100. To a certain extent, the space inside the shell of the equipment using the connecting rod device 100, such as the space inside the shell of an air compressor, can be reduced to connect the connecting rod to the piston of the air compressor.

[0150] In some embodiments, at least one of the first type of mounting component 120 , the second type of mounting component 140 , and the third type of mounting component 170 includes a bearing.

[0151] By including a bearing in at least one of the first type of mounting member 120, the second type of mounting member 140, and the third type of mounting member 170, the bearing is easy to obtain and can reduce the friction between the first type of connecting rod 130, the second type of connecting rod 150, the active member 160 and the corresponding mounting member to improve mechanical efficiency. At the same time, it can also support each connecting rod and the active member 160 to ensure the stable operation of each component. The use of bearings can also improve the reliability of the machine, especially when subjected to high-speed rotation and large loads.

[0152] refer to Figure 2 , along the axial direction of the central axis, the first type of mounting member 120 is located between the second type of mounting member 140 and the third type of mounting member 170 .

[0153] In some embodiments, reference Figure 7 The connecting rod device 100 further includes a locking ring 180 .

[0154] The locking ring 180 is used to apply a locking force to the first type connecting rod 130 and the second type connecting rod 150 so that the first type connecting rod 130 and the second type connecting rod 150 have a tendency to move toward the central axis 110a.

[0155] By setting a locking ring 180, a locking force can be applied to the first type of connecting rod 130 and the second type of connecting rod 150, so that the first type of connecting rod 130 and the second type of connecting rod 150 have a tendency to move toward the central axis 110a. In the process of the rotating shaft 110 driving the connecting rods to rotate, a locking ring 180 can be used to achieve radial limitation of each connecting rod on the central axis 110a, and it is used in conjunction with the action member 160 to further improve the stability of the connecting rod device 100 during use.

[0156] For example, reference Figure 6 and Figure 7A locking ring 180 is arranged at the axial end of the first type connecting rod 130 and the second type connecting rod 150 close to the action member 160, and a groove is opened on the outer peripheral wall surface of the first type connecting rod 130 and the second type connecting rod 150. The locking ring 180 can be accommodated by the groove to realize the connection between the locking ring 180 and various types of connecting rods.

[0157] The lock ring 180 can be constructed as an open lock ring 180. When the lock ring 180 is deformed to a certain extent and the locking force is insufficient, the locking force of the lock ring 180 on various connecting rods can be adjusted by adjusting the opening.

[0158] In some embodiments, reference Figure 1 The connecting rod device 100 also includes: a counterweight 190.

[0159] The counterweight 190 is used to rotate synchronously with the rotating shaft 110, wherein the rotation axis of the counterweight 190 is colinear with the central axis 110a.

[0160] By arranging the counterweight 190 to rotate synchronously with the rotating shaft 110 , the rotational inertia of the rotating shaft 110 can be increased, thereby preventing the entire connecting rod device 100 from vibrating excessively, thereby reducing the noise generated by the connecting rod device 100 .

[0161] Exemplarily, the counterweight 190 is configured as a counterweight balancing block, and is directly connected to the rotating shaft 110 .

[0162] In some embodiments, reference Fig. 9 The counterweight member 190 includes a connecting portion and a counterweight portion 192 .

[0163] The connecting portion is used to form a connection with the rotating shaft 110, and the counterweight portion 192 is used to form a connection with the power output shaft of the prime mover, wherein the counterweight portion 192 is located on one side of the plane where the central axis 110a is located.

[0164] The power output shaft of the prime mover can rotate through the counterweight part 192 to drive the connecting part to rotate, and the connecting part is connected to the rotating shaft 110, thereby achieving the effect of driving various connecting rods and mounting parts on the rotating shaft 110 to rotate. This structure realizes eccentric rotation through the counterweight part 190, and there is no need to add an additional eccentric connecting part.

[0165] In some embodiments, reference Fig. 9 , the connecting portion and the counterweight portion 192 are integrally formed.

[0166] In some embodiments, a dimension of the counterweight portion 192 along the central axis 110 a is greater than a dimension of the second type mounting member 140 along the central axis 110 a .

[0167] For example, reference Figure 3The dimension of the counterweight portion 192 along the central axis 110a is defined as L1, and the dimension of the second type mounting member 140 along the central axis 110a is defined as L2, and L1 is greater than L2.

[0168] In some embodiments, reference Fig. 9 The counterweight portion 192 further defines a connecting space 192a.

[0169] The connecting space 192a is used for partially extending the power output shaft of the prime mover so that the counterweight part 192 and the prime mover form a power coupling, wherein the center line of the connecting space 192a is parallel to the center axis 110a.

[0170] In some embodiments, reference Fig. 9 The combining portion 191 further defines a combining space 191a.

[0171] The combining space 191 a is utilized to allow a portion of the rotating shaft 110 to extend therein, so that the rotating shaft 110 is connected to the connecting portion, wherein the center line of the combining space 191 a is colinear with the center axis 110 a .

[0172] In some embodiments, the sum of the number of the first type of links 130 and the number of the second type of links 150 is an even number greater than zero.

[0173] The connecting rod device 100 of the present application can be adapted to a small compression device having more than two cylinders but an even number of total cylinders.

[0174] For example, the number of cylinders in a small compression device can be set to four cylinders.

[0175] Of course, the connecting rod device 100 of the present application can also be adapted to a small compression device with more than two cylinders and an odd number of cylinders. For example, the number of cylinders of the small compression device can be set to three cylinders, five cylinders or seven cylinders.

[0176] In some embodiments, the number of the first type of connecting rods 130 and the number of the second type of connecting rods 150 may be set to be the same.

[0177] By setting the number of the first type of connecting rods 130 and the number of the second type of connecting rods 150 to be the same, the overall force of the connecting rod device 100 can be further balanced to avoid affecting the movement stability of the connecting rod device 100.

[0178] For example, when the connecting rod device 100 of the present application is applied to a four-cylinder compression device, two first-type connecting rods 130 and two second-type connecting rods 150 may be provided.

[0179] When the connecting rod device 100 of the present application is applied to a six-cylinder compression device, three first-type connecting rods 130 and three second-type connecting rods 150 may be provided.

[0180] The first type of connecting rod 130 and the second type of connecting rod 150 of the present application have the same total length dimension along the radial direction of the central axis 110a, and both have a groove, but the depth of the groove is set differently. The depth of the groove of the first type of connecting rod 130 is less than the depth of the groove of the second type of connecting rod 150. Therefore, when the groove of the first type of connecting rod 130 and the groove of the second type of connecting rod 150 respectively accommodate the first type of mounting member 120, the first type of mounting member 120 can form a surface contact with the first type of connecting rod 130, while the second type of connecting rod 150 is spaced apart from the first type of connecting rod 130.

[0181] In the embodiment of the present application, a fastener may also be provided at one end of the third type mounting member 170 away from the first type mounting member 120 , and the fastener may be fastened to the rotating shaft 110 , thereby further improving the overall stability of the connecting rod device 100 .

[0184] In some embodiments, the working medium processing equipment includes an air compressor; wherein the air compressor includes a prime mover having a power output shaft.

[0185] The prime mover of the present application may be configured as an electric motor.

In the description of this application, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0191] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.

[0192] The above are only preferred embodiments of the present application and do not constitute any form of limitation to the present application.
