Description
Technical Field
The utility model relates to the technical field of compressors, in particular to a thrust structure of a compressor, the compressor and a vehicle.
Background
A compressor (compressor) is a driven fluid machine that lifts low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. The refrigerating cycle of compression, condensation (heat release), expansion and evaporation (heat absorption) is realized by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the air discharge pipe to provide power for the refrigerating cycle. The compressor is divided into a piston compressor, a screw compressor, a centrifugal compressor, a linear compressor, etc. The piston compressor generally consists of a housing, an electric motor, a cylinder, a piston, control devices (starter and thermal protector) and a cooling system. The cooling modes include oil cooling and air cooling, and natural cooling. The linear compressor has no shaft and no cylinder, sealing and heat dissipating structure. The compressors of the common household refrigerator and the air conditioner are powered by single-phase alternating current, and the structural principle of the compressors is basically the same, but the refrigerants used by the compressors are different.
Referring to fig. 2, for a rolling rotor compressor, the distance L1 between the upper thrust surface 122 and the lower thrust surface 121 of the crankshaft 120 is generally about 0.4mm less than the distance L2 between the upper end surface of the upper cylinder 180 and the lower end surface of the lower cylinder 170, i.e., l2=l1+0.4 mm. Accordingly, the crankshaft 120 has an axial gap in the axial direction (i.e., the direction in which the arrow m is located in fig. 1). In the case of a typical vertical compressor, the crankshaft 120 does not axially move due to gravity when the compressor is stopped. In the case of the horizontal compressor, particularly the horizontal compressor mounted on a vehicle, when the vehicle is in a driving state and the compressor is stopped, the crankshaft 120 is easily caused to move in the axial direction, and the upper thrust surface 122 and the lower thrust surface 121 are repeatedly impacted, causing a reliability problem. The conventional solution is that the horizontal compressor has a certain inclination, but this problem cannot be completely avoided.
It should be noted that the information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

One embodiment of a compressor thrust structure is disclosed with reference to fig. 1-3. The compressor thrust structure includes: a housing cover 110 configured with a first magnet assembly 140, the first magnet assembly 140 including a first magnet 142; a cylinder head coaxially disposed with the housing cover 110 (i.e., a central axis m of the compressor 100 in fig. 2); a crankshaft 120 movably connected to the cylinder head and disposed coaxially with the housing cover 110 and the cylinder head (i.e., a central axis m of the compressor 100 in fig. 2), the crankshaft 120 being configured with a second magnet assembly 150, the second magnet assembly 150 including a second magnet 152; the first magnet 142 and the second magnet 152 are coaxially disposed (i.e., the central axis m of the compressor 100 in fig. 2), and the first magnet 142 and the second magnet 152 are disposed with the same-name magnetic poles facing each other, so as to limit the axial movement of the crankshaft 120.
The cylinder cover comprises an upper cylinder cover 160 and a lower cylinder cover 130, wherein the crankshaft 120 is provided with an upper thrust surface 122 and a lower thrust surface 121, the upper thrust surface 122 is abutted with the upper cylinder cover 160, and the lower thrust surface 121 is abutted with the lower cylinder cover 130.
For a conventional horizontal compressor, the crankshaft 120 easily moves in the axial direction, so that the portion where the upper thrust surface 122 abuts against the upper cylinder head 160 and the portion where the lower thrust surface 121 abuts against the lower cylinder head 130 repeatedly collide. Thereby causing a problem of low reliability.
However, in this embodiment, by providing the compressor thrust structure inside the compressor 100, by providing the first magnet 142 and the second magnet 152, and disposing the same-name magnetic poles of the first magnet 142 and the second magnet 152 opposite to each other, the crankshaft 120 can be subjected to the force of the mutual repulsion of the magnets due to the mutual repulsion of the same-name magnetic poles, and the lower thrust surface 121 of the crankshaft 120 can be closely attached to the lower cylinder cover 130, so as to solve the problem of axial movement of the crankshaft 120.

At the same time, the reliability of the compressor 100 is also improved.

One end of the protruding portion 151 is fixedly connected to the crankshaft 120, and the other end of the protruding portion 151 is fixedly connected to the second magnet 152. The second magnet 152 is coupled to the protruding portion 151. Next, the limiting portion 153 is fixedly connected to the other end of the protruding portion 151, so as to limit and fix the second magnet 152. The limiting portion 153 may be a fixing plate, which is fixedly connected to the protruding portion 151, so as to implement limiting fixation of the second magnet 152. The limiting portion 153 may be a nut, and the limiting fixation of the second magnet 152 may be achieved by providing a threaded portion 154 at the other end of the protruding portion 151 and screwing the nut to the threaded portion 154.
