Further, the compression mechanism has a crankshaft 21, the crankshaft 21 has a crankshaft thrust surface 22, the thrust mechanism 3 is provided in the housing 1, the thrust mechanism 3 has a first thrust plate 31 and an elastic member 32, and the elastic member 32 elastically cooperates with the first thrust plate 31 to press the first thrust plate 31 against the crankshaft thrust surface 22 of the crankshaft 21. That is to say, the compression mechanism and the thrust mechanism 3 are both disposed in the housing 1, and the elastic member 32 has a tendency of pushing the first thrust plate 31 to move toward the crankshaft thrust surface 22, so that under the action of the elastic member 32, the first thrust plate 31 can be kept in a state of abutting against the crankshaft thrust surface 22, and then the thrust effect of the thrust mechanism 3 on the crankshaft 21 is ensured, so as to prevent the crankshaft 21 from generating an excessive position deviation, which is favorable for improving the reliability of the compressor 100. In addition, when the acting force of the crankshaft 21 on the first thrust plate 31 is increased, the first thrust plate 31 is pushed to extrude the elastic member 32 to deform in the direction close to the elastic member 32, that is, the first thrust plate 31 has a certain flexible avoidance space through the elastic member 32, so that the first thrust plate 31 can be better prevented from being rigidly contacted with the crankshaft thrust surface 22 to damage the thrust mechanism 3, meanwhile, the friction noise between the first thrust plate 31 and the crankshaft thrust surface 22 can be reduced, and the reliability and silent performance of the compressor 100 can be improved.

When the downward acting force of the crankshaft 21 increases, the pressure acting on the first thrust plate 31 increases, the first thrust plate 31 presses the elastic member 32 downward to deform, so that the rigid contact between the first thrust plate 31 and the crankshaft thrust surface 22 is buffered, when the downward acting force of the crankshaft 21 decreases, the pressure acting on the first thrust plate 31 decreases, and the elastic member 32 recovers to deform to push the first thrust plate 31 to move upward, that is, the elastic member 32 enables the first thrust plate 31 to have a certain flexible avoidance space in the up-down direction.

According to some embodiments of the present invention, the elastic member 32 is disposed on a side of the first thrust plate 31 facing away from the crankshaft thrust surface 22. That is, the crankshaft thrust surface 22 and the elastic member 32 are respectively disposed on two opposite sides of the first thrust plate 31, so that the elastic member 32 can be prevented from affecting the rotation of the crankshaft 21, and meanwhile, the rotating crankshaft 21 can be prevented from wearing the elastic member 32, so that the service life of the elastic member 32 is prolonged, that is, the elastic member 32 and the crankshaft 21 can be prevented from interfering with each other, thereby facilitating the improvement of the reliability of the thrust mechanism 3, and the layout is reasonable. In a specific example, the crankshaft thrust surface 22 is formed on a lower end surface of the crankshaft 21, the first thrust plate 31 is disposed on a lower side of the crankshaft thrust surface 22 and is opposite to the crankshaft thrust surface 22 in an up-down direction, the elastic member 32 is disposed on the lower side of the first thrust plate 31, and the elastic member 32 is used for pushing the first thrust plate 31 to move upward to ensure an effect that the first thrust plate 31 supports the crankshaft 21 upward. In addition, permanent damage to the elastic member 32, such as the coil spring 322, caused by an excessive downward movement of the crankshaft 21 can be avoided, which is beneficial to ensure the stability of the elastic member 32.

Further, as shown in fig. 1, 5 and 7, the thrust mechanism 3 further includes: a second thrust plate 33, the second thrust plate 33 being fixed in the housing 1, the elastic member 32 being disposed between the first thrust plate 31 and the second thrust plate 33.

Therefore, the first thrust plate 31 can be pushed to be pressed against the crankshaft thrust surface 22 through the deformation of the upper convex part, and the first thrust plate 31 can have a certain flexible avoidance space. Specifically, when the acting force of the crankshaft 21 on the first thrust plate 31 increases, the first thrust plate 31 presses the elastic sheet structure 321, so that the upper convex part moves towards the direction close to the second thrust plate 33, the first thrust plate 31 moves towards the direction close to the second thrust plate 33, and when the acting force of the crankshaft 21 on the first thrust plate 31 decreases, the upper convex part returns to be deformed towards the direction away from the second thrust plate 33, so as to push the first thrust plate 31 to move towards the direction away from the second thrust plate 33, and thus the thrust effect of the thrust mechanism 3 on the crankshaft 21 is ensured. For example, the elastic sheet structure 321 may be a wave spring, which has a large stiffness range, strong shock absorbing capability, large material variation per unit volume, high strength, good flexibility, strong impact resistance, and compact structure size.

That is, the plurality of coil springs 322 may be arranged in order of increasing radial dimension from smaller radial dimension toward the outer peripheral side of the crankshaft 21 along the radial direction of the crankshaft 21, that is, the coil spring 322 having a larger radial dimension is fitted around the outer peripheral side of the coil spring 322 having a smaller radial dimension. From this, can increase the area of contact between a plurality of coil springs 322 and first thrust plate 31 and the second thrust plate 33 betterly, a plurality of coil springs 322 can bear bigger pressure, and it is effectual to kick-back, when guaranteeing that first thrust plate 31 has certain flexibility and dodges the space, can guarantee thrust mechanism 3 better to the thrust effect of bent axle 21.

In addition, make thrust mechanism 3 to fix in casing 1 through frame 4, can reduce the installation degree of difficulty of thrust mechanism 3 betterly, and the influence to other inner structure of compressor 100 is less in thrust mechanism 3 later maintenance operation.
