[0029] like Figures 1-5 As shown, the present invention provides a compressor housing with an integrated liquid receiver, including a main housing 1, a top cover 2, and a bottom cover 3. The top cover 2 is disposed on the top of the main housing 1, and the bottom cover 3 is disposed on the bottom of the main housing 1. A sealed cavity is formed between the top cover 2, the bottom cover 3, and the main housing 1. A partition 4 is provided in the main housing 1, which divides the sealed cavity into a high-pressure cavity and a low-pressure cavity 11. The low-pressure cavity 11 is a liquid receiver, and the high-pressure cavity includes a first cavity 12 and a second cavity 13. The drive motor 5 of the compressor is disposed in the first cavity 12, and the pump body 6 of the compressor is disposed in the second cavity 13.
[0030] The compressor housing with integrated liquid receiver of the present invention has a partition 4 set inside the main housing 1. The partition 4 divides the sealed cavity of the main housing 1 into a high-pressure chamber and a low-pressure chamber 11, wherein the low-pressure chamber 11 is a liquid receiver. In other words, the liquid receiver in the prior art is integrated into the main housing 1. Unlike the prior art where the liquid receiver is externally attached to the outer wall of the main housing 1 by welding, the main housing 1 is made of lightweight aluminum alloy, which reduces the overall weight of the compressor and meets the requirements of compressor lightweighting.
[0031] Preferred, such as Figures 1-3 As shown, the partition 4 includes a vertical plate 41 and a horizontal plate 42. The two side walls of the vertical plate 41 are connected to the inner wall of the main housing 1. The horizontal plate 42 is disposed at the bottom end of the vertical plate 41, and the end of the horizontal plate 42 away from the vertical plate 41 is connected to the inner wall of the main housing 1. A low-pressure cavity 11 is formed between the vertical plate 41, the horizontal plate 42, the main housing 1 and the top cover 2. A high-pressure cavity is formed between the vertical plate 41, the horizontal plate 42, the main housing 1, the top cover 2 and the bottom cover 3.
[0032] In this embodiment, as Figure 2As shown, the vertical plate 41 has a semi-arc cross-sectional shape along the horizontal plane and extends vertically. The horizontal plate 42 extends horizontally and is disposed between the bottom end of the vertical plate 41 and the inner wall of the main housing 1. At this time, the vertical plate 41 and the horizontal plate 42 have an L-shaped cross-sectional shape along the vertical direction. The low-pressure chamber 11 and the high-pressure chamber are separated by the partition 4, and the low-pressure chamber 11 and the high-pressure chamber are not connected to each other.
[0033] Preferred, such as Figures 1-3 As shown, the high-pressure chamber has an L-shaped cross-section in the vertical direction; the first chamber 12 extends vertically, and the second chamber 13 is located below the first chamber 12 and extends horizontally; a liquid storage chamber vent 420 is provided on the horizontal plate 42, the upper end face of the pump body 6 is attached to the lower end face of the horizontal plate 42, and a suction port connected to the cylinder 62 is provided on the pump body 6. The liquid storage chamber vent 420 is correspondingly connected to the suction port, and the drive motor 5 drives the pump body 6 to compress the gas in the liquid storage chamber vent 420. The central axes of the high-pressure chamber and the low-pressure chamber 11 are parallel to each other.
[0034] Furthermore, such as Figure 1 , Figure 3 As shown, the pump body 6 includes an upper cylinder cover 61, a lower cylinder cover 63, a cylinder 62, and a crankshaft 64. The upper cylinder cover 61 is located on the top surface of the cylinder 62, and the lower cylinder cover 63 is located on the bottom surface of the cylinder 62. The crankshaft 64 is located inside the cylinder 62 and is connected to the drive motor 5. The upper surface of the cylinder 62 is attached to the lower surface of the horizontal plate 42, and the suction port passes through the upper surface of the cylinder 62 and communicates with the outlet port 420 of the liquid storage chamber; or the upper surface of the upper cylinder cover 61 is attached to the lower surface of the horizontal plate 42, and the suction port passes through both the upper and lower surfaces of the upper cylinder cover 61. One end of the suction port communicates with the outlet port 420 of the liquid storage chamber, and the other end communicates with the cylinder 62.
[0035] In this embodiment, as Figure 2 , Figure 3 As shown, the vertical plate 41 has a semi-arc cross-section along the horizontal plane, and the inner wall of the main housing 1 in the first cavity 12 is also semi-arc. Therefore, the inner wall of the main housing 1 in the first cavity 12 and the vertical plate 41 together form a circle. The drive motor 5 is installed on the inner wall of the first cavity 12, and a crankshaft 64 is connected to the rotor of the drive motor 5. The crankshaft 64 is connected to the piston located in the cylinder 62 of the pump body 6. When the drive motor 5 drives the rotor to rotate, the crankshaft 64 drives the piston to rotate in the cylinder 62, and the volume of the gas in the cylinder 62 changes, thereby compressing the low-temperature, low-pressure gas in the cylinder 62 into a high-temperature, high-pressure gas.
[0036] Furthermore, several pump body connection holes 421 are provided on the bottom surface of the horizontal plate 42. Bolts or screws are passed through the upper cylinder cover 61 to securely connect the upper cylinder cover 61 to the pump body connection holes 421 on the horizontal plate 42. In addition, bolts or screws are also passed through the cylinder 62 to securely connect the cylinder 62 to the pump body connection holes 421 on the horizontal plate 42.
[0037] Preferred, such as Figures 1-3 As shown, a vertical plate connecting portion 410 is provided on the side of the vertical plate 41 near the low-pressure cavity 11. The vertical plate connecting portion 410 has a vertical plate connecting hole 411 for connecting with the top cover 2.

The low-pressure chamber main housing connecting part 110 has a low-pressure chamber main housing connecting hole 111 for connecting with the top cover 2. In this embodiment, the low-pressure chamber main housing connecting part 110 extends into the low-pressure chamber 11 in the horizontal direction and extends towards the bottom cover 3 in the vertical direction.
[0039] Preferred, such as Figures 1-3 As shown, the main shell 1 in the first cavity 12 has a first cavity main shell connection hole 120 on its shell wall, which connects to the top cover 2. In this case, the shell wall of the main shell 1 in the first cavity 12 should have a certain thickness to accommodate the first cavity main shell connection hole 120. In other embodiments, the outer wall of the main shell 1 in the first cavity 12 is provided with a first cavity main shell connecting portion (not shown), which has a first cavity main shell connecting hole 120 for connection to the top cover 2. The first cavity main shell connecting portion extends horizontally into the first cavity 12 and vertically towards the bottom cover 3.
[0040] In this embodiment, as Figure 4 As shown, the top cover 2 has several top cover connection holes 23, which correspond one-to-one with the vertical plate connection hole 411, the low-pressure chamber main housing connection hole 111, and the first chamber main housing connection hole 120, and are fastened together by bolts or screws, thus enabling the top cover 2 to be installed on the main housing 1. In addition, to ensure a tight connection between the top cover 2 and the main housing 1, the top end of the vertical plate 41 is at the same horizontal level as the top end of the main housing 1 and both abut against the top cover 2. Sealing gaskets are provided between the main housing 1 and the top cover 2, and between the vertical plate 41 and the top cover 2 to ensure airtightness.
[0041] Preferred, such as Figures 1-3As shown, a second cavity main shell connecting part 121 is provided on the inner wall of the main shell 1 in the second cavity 13. The second cavity main shell connecting part 121 has a second cavity main shell connecting hole 122 for connecting with the bottom cover 3. In this embodiment, the second cavity main shell connecting part 121 extends into the second cavity 13 in the horizontal direction and extends towards the horizontal plate 42 in the vertical direction.
[0042] like Figure 3 , Figure 5 As shown, the bottom cover 3 has several bottom cover connection holes 31, which correspond one-to-one with the connection holes 122 of the main housing of the second cavity, and are fastened together by bolts or screws, thus enabling the bottom cover 3 to be installed on the main housing 1. In addition, to ensure a tight connection between the bottom cover 3 and the main housing 1, a sealing gasket is provided between the bottom cover 3 and the main housing 1 to ensure airtightness.
[0043] Preferred, such as Figure 1 As shown, the top cover 2 is provided with an air inlet pipe 22 and an exhaust pipe 21. The air inlet pipe 22 is connected to the low-pressure chamber 11, and the exhaust pipe 21 is connected to the high-pressure chamber. Figure 4 The intake pipe 22 and exhaust pipe 21 are not shown.
[0044] Preferred, such as Figure 5 As shown, the end face of the top cover 2 near the sealing cavity is a flat plate or a recessed type; the end face of the bottom cover 3 near the sealing cavity is a flat plate or a recessed type. In this embodiment, the end faces of the top cover 2 and the bottom cover 3 near the sealing cavity are recessed, that is, grooves 32 are provided on the bottom end face of the top cover 2 and the top end face of the bottom cover 3, thereby increasing the volume of the high pressure cavity and the low pressure cavity 11 and reducing the noise of the compression assembly during operation.
[0045] Preferably, in this embodiment, the main housing 1 and the partition 4 are integrally formed.
[0046] To achieve the above or other objectives, the present invention also discloses a vehicle air conditioner, including a compressor housing with the aforementioned integrated liquid receiver.
[0047] The compressor housing of the integrated liquid receiver involved in this invention operates on the following principle:
[0048] First, during the manufacturing of the main housing 1, a partition 4 is integrally formed within the main housing 1. The partition 4 includes a vertical plate 41 and a horizontal plate 42. The vertical plate 41 has a semi-arc cross-sectional shape along the horizontal plane and extends vertically. The horizontal plate 42 is disposed on the bottom end face of the vertical plate 41 and extends horizontally. The end face of the horizontal plate 42 away from the vertical plate 41 is fixedly connected to the inner wall of the main housing 1. Thus, the vertical plate 41 and the horizontal plate 42 divide the main housing 1 into an independent high-pressure chamber and a low-pressure chamber 11. The low-pressure chamber 11 is a liquid storage chamber, and the high-pressure chamber is used to house the drive motor 5 and the pump body 6.
[0049] Secondly, a vertical first cavity 12 is formed between the main housing 1 and the vertical plate 41, and a horizontal second cavity 13 is formed between the main housing 1 and the horizontal plate 42. The drive motor 5 is fixedly installed in the first cavity 12, and the pump body 6 is fixedly installed in the second cavity 13. The pump body 6 includes an upper cylinder head 61, a lower cylinder head 63, a cylinder 62, and a crankshaft 64. Several pump body connection holes 421 are provided on the bottom surface of the horizontal plate 42. The upper cylinder head 61 and the cylinder 62 are fastened to the horizontal plate 42 through the pump body connection holes 421 and bolts or screws, thereby fixing the pump body 6 in the second cavity 13. At the same time, the horizontal plate 42 is also provided with a liquid storage chamber vent 420, which is connected to the pump body 6 to provide low-pressure, low-temperature gas.
[0050] Finally, the top inner wall of the main housing 1 is provided with a low-pressure chamber main housing connection part 110 and a first chamber main housing connection part. Both the low-pressure chamber main housing connection part 110 and the first chamber main housing connection part have corresponding connection holes for fastening to the top cover 2. The top side of the vertical plate 41 is provided with a vertical plate connection part 410, which has corresponding vertical plate connection holes 411 for fastening to the top cover 2. The bottom inner wall of the main housing 1 in the second chamber 13 is provided with a second chamber main housing connection part 121, which has corresponding second chamber main housing connection holes 122 for fastening to the bottom cover 3. Thus, the top cover 2 and the bottom cover 3 are respectively installed onto the main housing 1 through the aforementioned connection holes.
[0051] The present invention relates to a compressor housing and vehicle air conditioner with an integrated liquid receiver. The separator 4 and the main housing 1 are integrally formed, which is simple to manufacture and compact. At the same time, the top cover 2 and the bottom cover 3 are both set on the main housing 1 through connecting parts, which can realize the weight reduction of the compressor. The separator 4 divides the main housing 1 into a high-pressure chamber and a low-pressure chamber 11, wherein the low-pressure chamber 11 serves as a liquid receiver, that is, the liquid receiver in the prior art is integrated into the main housing 1, which solves the problem of the liquid receiver being externally welded to the outside of the main housing 1 in the prior art. The end faces of the top cover 2 and the bottom cover 3 relative to the sealed cavity can be set to be concave in the middle, which can increase the volume of the high-pressure chamber and the low-pressure chamber 11 and effectively improve noise.
[0052] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
