As shown in fig. 1, a compressor 100 according to an embodiment of the present invention includes: housing 110, crankcase 120, motor 130, cylinder 140, crankshaft 150, and shield assembly 160. It is understood that the housing 110 may serve as a protective member for protecting and dust-proof the crankcase 120, the motor 130, the cylinder 140, and the crankshaft 150 disposed in the housing 110. The crankcase 120 may be a supporting member of the cylinder 140 and the crankshaft 150. Motor 130 may provide power for rotation of crankshaft 150. The cylinder 140 may be a functional part that performs a compression function of the compressor 100. Crankshaft 150 may be an intermediate member that transmits power of motor 130. The guard assembly 160 may protect the crankcase 120, and the cylinders 140 and crankshaft 150 thereon, from damage due to impact or vibration.

Specifically, referring to fig. 1, the crankcase 120 is provided in the housing 110. The motor 130 is located on one side 121 of the crankcase 120, and the motor 130 is connected to the crankcase 120. The cylinder 140 is located on the other side 122 of the crankcase 120, and the cylinder 140 is connected to the crankcase 120. The crankshaft 150 is inserted through the crankcase 120 and the motor 130. The shield assembly 160 is coupled to the crankcase 120 to prevent the crankcase 120 from colliding with the housing 110. Therefore, the motor 130 and the crankcase 120 are connected to each other, so that the motor 130 and the crankcase 120 can be firmly combined, a reliable installation environment can be provided for the crankshaft 150, the motor 130 located on one side 121 of the crankcase 120 can provide power for the crankshaft 150, the crankshaft 150 transmits the power of the motor 130 to the cylinder 140 located on the other side 122 of the crankcase 120, the piston of the cylinder 140 can be driven to reciprocate, and the cylinder 140 can compress refrigerant, so that the compression function of the compressor 100 is realized. After the cylinder 140 is connected to the crankcase 120, the crankcase 120 can provide stable support for the cylinder 140, which is beneficial to improving the reliability of the operation of the cylinder 140.

As shown in fig. 1, the shield assembly 160 may include a bumper 161 and a reinforcement 162. The bumper 161 has a connecting leg 1614 at one end, the connecting leg 1614 is connected to the crankcase 120, and the connecting leg 1614 is plural, wherein at least one connecting leg 1614 is located on one side of the crankcase 120, and at least one connecting leg 1614 is located on the other side of the crankcase 120. It is understood that the connecting legs 1614 are located at both sides of the crankcase 120 to stably mount the bumper 161 on the crankcase 120, and the plurality of connecting legs 1614 can enhance the mounting reliability.

The other end of the bumper 161 has a bent portion 1611, the bent portion 1611 and the other side 122 of the crankcase 120 define an installation space 1612, and the cylinder 140 is located in the installation space 1612. The installation space 1612 defined by the bent portion 1611 and the other side 122 of the crankcase 120 may provide an installation area for the cylinder 140, and may also protect the cylinder 140 by using the bent portion 1611. Therefore, the protection function of the protection assembly 160 can be realized, and the possibility of damaging parts such as the cylinder 140, the crankshaft 150, the motor 130 and the like in the shell 110 due to collision can be reduced. In addition, it should be noted that, when the reinforcement member 162 is assembled to the crankcase 120, the reinforcement member 162 and the bumper member 161 may be connected together, and then the reinforcement member 162 and the bumper member 161 may be mounted to the crankcase 120 together.

In the transportation process of the compressor or the refrigerator, violent shaking is inevitably generated, so that the shell and internal parts are continuously collided by the violent shaking, and the core parts of the compressor are easily damaged in severe cases. In order to avoid direct collision between the shell and the internal parts, the limiting and anti-collision device is needed to limit and protect the internal parts of the shell.

In the compressor 100 according to the embodiment of the present invention, the protective assembly 160 is mounted on the crankcase 120, so that the probability of collision between the housing 110 and the internal components of the housing 110 can be reduced by the protective effect of the protective assembly 160, and the crankcase 120 inside the housing 110, and the cylinder 140, the crankshaft 150, the motor 130, and other components located around the crankcase 120 can be protected.

Referring to fig. 1-2, according to further embodiments of the invention, the connecting leg 1614 has an abutment 1615, and the abutment 1615 abuts a surface of the crankcase 120.

Referring to fig. 1-2, according to some embodiments of the present invention, the bent portion 1611 has a mounting hole 1613, and the reinforcement 162 is disposed through the mounting hole 1613. Therefore, the reinforcement 162 and the anti-collision piece 161 can be reliably connected, and when the compressor 100 collides and shakes, the probability that the reinforcement 162 and the anti-collision piece 161 are separated from each other can be reduced, so that the anti-collision piece 161 can be improved to have more stable protection performance, and the cylinder 140 and other parts can be better protected.

According to some embodiments of the present invention, as shown in fig. 1, the crankcase 120 has a mounting platform 125, and the attaching portion 1615 is attached and connected to the mounting platform 125. The mounting platform 125 of the crankcase 120 may provide support for the attachment portion 1615, making the attachment portion 1615 more stable. According to further embodiments of the present invention, the attaching portion 1615 and the mounting platform 125 are connected by screws. The screw connection can enhance the mounting strength between the attaching portion 1615 and the mounting platform 125, so that the attaching portion 1615 is reliably mounted on the mounting platform 125 and is not easily detached.
