Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigeration equipment, specifically to horizontal compressors and new energy vehicles. Background Art

[0002] As an excellent option among the fourth-generation refrigerants HFOs, R290 has an extremely broad application market. However, due to its flammability, the system charge amount of R290 is restricted, and the current product charge amount is generally 150 g. To ensure that the system performance meets the requirements, the oil injection amount of the system is also correspondingly reduced. Therefore, the management of the oil in the system is very important. It is necessary to ensure that the limited oil can lubricate each friction surface, minimize the space where oil can be stored, and prevent the occurrence of dead volume.

[0003] Patent CN101809286A introduces a drive circuit integrated electric compressor, which houses a compression mechanism part and a motor for driving the compression mechanism part, and has a drive circuit of the motor built in. Between the drive circuit setting part and the motor setting part, a refrigerant gas chamber composed of a refrigerant gas diffusion space for introducing refrigerant gas is formed by a first partition wall provided on the drive circuit side and a second partition wall provided on the opposite motor side. The refrigerant gas chamber is partitioned from the drive circuit setting part by the first partition wall, and is communicated with the motor setting part through a through hole provided in the second partition wall through which the refrigerant gas can pass. In the drive circuit integrated electric compressor, in particular, it is easy and effective to cool the heat generating components in the drive circuit, and even for the motor setting part side, it is easy and better to maintain the cooling of the motor and the lubrication of the bearing part.

[0004] Patent CN114941624A provides a compressor rear shell assembly and a scroll compressor including the same. The compressor rear shell assembly includes a rear shell body and a mounting plate hermetically connected to the rear shell body; the rear shell body is provided with a suction port, an air flow channel and at least one first air circulation hole; when the rear shell assembly is used for a compressor, one side of the rear shell body is a refrigerant chamber, and the other side forms a heat dissipation chamber with the mounting plate. The heat dissipation chamber is communicated with the suction port through the air flow channel; the heat dissipation chamber is communicated with the refrigerant chamber through at least one first air circulation hole. The scroll compressor of the utility model has a controller cooling function, and uses the inhaled low-temperature refrigerant to intensively exchange heat with the heat dissipation surface of the controller power module. The low-temperature refrigerant also lubricates the auxiliary bearing area at the same time, improving the reliability and durability of the compressor; the compressor of the utility model does not need to change its external structure and add additional cooling pipelines, and has the advantages of simple cooling structure and sealing structure and high reliability.

[0005] The above two patents innovated on the cooling structure of the controller, focusing on using refrigerant to flush and convectively exchange heat with the housing to cool the controller. However, they did not further consider the particularity of using R290 refrigerant. Considering that the system charge of R290 is low and will not exceed 200 g, in order to meet the system energy efficiency requirements, the lubricating oil injection volume in the system generally will not exceed 120 ml. For compressors with a displacement of 45 cc or larger, to ensure the normal operation of the compressor, it is necessary to ensure that the lubricating oil does not accumulate in the dead volume area and should participate in the system cycle as much as possible to lubricate each working surface.

[0006] Moreover, the compressors of the prior art have many restrictions on the direction of the suction port and cannot arbitrarily adjust the position of the suction port. When used as an in-vehicle compressor for new energy vehicles, this will severely limit the module layout in the vehicle and reduce the application range of the compressor.

[0007] In view of this, the present utility model provides a horizontal compressor and a new energy vehicle. Summary of the Utility Model

[0069] Figure 1It is a cross-sectional view of the first horizontal compressor of the utility model. Figure 2 It is a partial exploded view of the first horizontal compressor of the utility model. Figure 3 It is a schematic diagram of a controller housing in the first horizontal compressor of the utility model. Figure 4 This is a schematic diagram of the first horizontal compressor of the utility model in which the baffle and the rear shell are integrally formed. Figures 1 to 4 As shown, the first horizontal compressor of the utility model comprises: a rear cover shell 1, a controller shell 3, a baffle 5 and a rear shell 6. Among them, the controller shell 3 is embedded with an air intake passage 32, the first side of the controller shell 3 and the rear cover shell 1 are surrounded to form a controller chamber 2, and the second side is concave to form an inner cavity, and the upper part of the inner cavity is provided with a first air intake hole 33, and the air intake passage 32 (should be an embedded structure, and the surface is not beautiful) is provided with a first air intake hole 33. Figure 3 The first side of the baffle 5 is connected to the second side of the controller housing 3, and the baffle 5 covers the inner cavity to enclose the first chamber 4. The rear shell 6 is connected to the second side of the baffle 5, and the rear shell 6 and the second side of the baffle 5 enclose the second chamber 9. Only the lower part of the baffle 5 is provided with a second air intake hole 53 for the refrigerant in the first chamber 4 to enter the second chamber 9. When the horizontal compressor of the utility model is working, since only the second air intake hole 53 immersed in the liquid refrigerant at the lower part of the baffle 5 is connected between the first chamber 4 and the second chamber 9, both the gaseous refrigerant and the liquid refrigerant can only enter the second chamber 9 through the second air intake hole 53. At this time, the flow of the gaseous refrigerant is more likely to excite or carry the liquid refrigerant at the bottom of the first chamber 4 to spray to various components in the second chamber 9, thereby improving the overall lubrication efficiency of the compressor. The utility model designs the air intake structure so that the refrigerant can bring the lubricating oil into the scroll when the scroll sucks air, thereby ensuring the normal oil circulation of the compressor and the reliability of its operation. At the same time, since the air intake port 31 in the utility model is no longer directly connected to the first chamber 4, it must pass through the curved pipeline formed by the air intake channel 32 and the first air intake hole 33 to connect to the first chamber 4, which will not affect the deposition of liquid refrigerant at the bottom of the first chamber 4. Therefore, the air intake port 31 can be set at different positions of the controller housing 3, and the longer air intake channel 32 can also use low-temperature refrigerant to cool the controller chamber 2. The utility model can avoid too many restrictions on the direction of the air intake port 31 through structural design. The air intake port 31 does not affect the operation of the compressor in any direction, and the arrangement conditions of the compressor in the system are further relaxed, which is particularly conducive to the layout in new energy vehicles with narrow space.

[0070] In a preferred embodiment, a secondary bearing seat 35 is provided at the center of the second side of the controller housing 3. On one side of the secondary bearing seat 35, a diversion side wall 39 extending in a direction perpendicular to the liquid level is provided. The thickness of the diversion side wall 39 is equal to the thickness of the first chamber 4. The diversion side wall 39 divides the first chamber 4 and defines a part of the first chamber 4 as a drainage channel 391 from the first suction through hole 33 to the bottom of the first chamber 4, but not limited thereto.

[0071] In a preferred embodiment, at least a part of the first suction through hole 33 is embedded in the diversion side wall 39. The diversion side wall 39 has a diversion hole 392 for guiding the refrigerant flow to the secondary bearing seat 35, and the secondary bearing seat 35 is effectively lubricated through the diversion hole 392, but not limited thereto.

[0072] In a preferred embodiment, the first suction through hole 33 is arranged above the liquid level of the refrigerant in the first chamber 4, but not limited thereto.

[0073] In a preferred embodiment, a plurality of bolt through holes 54 are provided in the circumferential direction of the baffle 5, and a plurality of bolt holes 36 are provided in the circumferential direction of the inner cavity of the controller housing 3. The bolt through holes 54 are screwed with the bolt holes 36, but not limited thereto.

[0074] In a preferred embodiment, a terminal post 34 is provided on the second side of the controller housing 3. An upper part of the baffle 5 is provided with a terminal post through hole 52 for the terminal post 34 to pass through, and a bearing through hole 51 for the secondary bearing seat 35 to pass through is provided at the center of the baffle 5, but not limited thereto.

[0075] In a preferred embodiment, it further includes:

[0076] A middle shell 10, and a first end of the middle shell 10 is connected to the rear shell 6 through a bracket 7.

[0077] A front shell 11, which is connected to the second end of the middle shell 10 and encloses an internal space for accommodating a motor, a moving scroll (not shown in the figure), and a stationary scroll 8, but not limited thereto.

[0078] In a preferred embodiment, the controller housing 3 is further provided with an exposed high-voltage wiring socket 37 and a low-voltage wiring socket 38, but not limited thereto.

[0079] In a preferred embodiment, the rear shell 6 and the baffle 5 are integrally formed, but not limited thereto.

[0080] Figure 5 It is a partial exploded view of the second horizontal compressor of the present utility model. Refer to Figure 5As shown in the figure, the difference between the second horizontal compressor of the present utility model and the first horizontal compressor lies in that the rear shell 6 and the baffle 5 are separated from each other. Specifically, the baffle 5 is a part independent of the rear shell 6. The baffle 5 and the controller housing enclose the first chamber 4, and the baffle 5 and the rear shell 6 enclose the second chamber 9. The baffle 5 is fixed by bolts. The remaining relevant technical features and technical effects are as described above and will not be elaborated here.

[0081] The present utility model relates to an electric compressor suitable for R290 refrigerant. By using the designed compressor structure, when the compressor can meet the modular design, the suction port orientation can be adjusted arbitrarily, and on this basis, it is ensured that during the refrigerant flow process, the oil in the oil sump at the bottom of the compressor can be brought into the scroll for circulation to ensure the normal operation of the compressor.

[0082] The following combines the description with the attached Figures 1 to 4 drawings to introduce the specific implementation manners of the horizontal compressor of the present utility model:

[0083] This patent proposes a vehicle compressor with a modular design adapted to R290 refrigerant, which is composed of a rear cover shell 1, a controller housing 3, a rear shell 6, a middle shell 10, a stationary scroll 8, a front shell 11, etc. Among them, the controller housing 3 is provided with a secondary bearing seat 35, a suction port 31, a suction passage 32, a first suction through hole 33, a terminal 34, a connecting bolt hole 36, and a diversion side wall 39. Among them, the suction port 31 can be located at any position in the 360° circumferential direction.

[0084] System intake air enters the suction passage 32 through the suction port 31. The suction passage 32 is a passage independent of the low-pressure chamber (controller chamber 2) of the compressor and is connected to the first chamber 4 through the first suction through hole 33. When the compressor operates, the mixture of refrigerant and lubricating oil enters the first chamber 4 via the suction port 31 → suction passage 32 (the controller chamber 2 will be cooled when passing through the suction passage 32) → first suction through hole 33. The position of the first suction through hole 33 is higher than the liquid level of the oil sump inside the compressor, ensuring that the lubricating oil will not flow out through the suction port during the installation, use, and disassembly of the compressor, so as to ensure the internal oil storage capacity of the compressor and the convenience during assembly.

[0085] The rear housing 6 includes a baffle 5, a bearing through-hole 51, a terminal through-hole 52, a second suction through-hole 53, and a bolt through-hole 54. Among them, the bearing through-hole 51 and the terminal through-hole 52 are respectively used to pass through the auxiliary bearing seat 35 and the terminal 34 structure on the controller housing 3 and are connected to the front-side crankshaft, motor, etc.; the bolt through-hole 54 thereon is used to install the bolts connecting the rear housing 6 and the controller housing 3; the baffle 5 is used to separate the first chamber 4 and the second chamber 9 after being assembled with the controller housing 3, and the second suction through-hole 53 is arranged at the bottom oil sump and communicates the first chamber 4 and the second chamber 9. The second suction through-hole 53 can allow the liquid refrigerant (mixed with liquid lubricating oil) at the bottom of the first chamber 4 to flow into the second chamber 9. At this time, the flow of the gaseous refrigerant is more likely to stimulate or carry the liquid refrigerant at the bottom of the first chamber 4 to spray onto each component in the second chamber 9, thereby improving the overall lubrication efficiency of the compressor, promoting all the lubricating oil to participate in the system circulation, and enhancing the reliability of the compressor operation.

[0086] The flow principle of the refrigerant in the compressor of the present utility model under the working state is as follows: The refrigerant fluid enters the suction port 31 and then enters the first chamber 4 through the suction passage 32 and the first suction through-hole 33. The first chamber 4 is formed after the connection of the controller housing 3 and the rear housing 6. Its bottom is the controller housing 3, and the top is the baffle 5 structure on the rear housing 6, and is connected to the external suction passage and the second chamber 9 through the first suction through-hole 33 and the second suction through-hole 53 respectively. Because the first suction through-hole in the first chamber 4 is opened at a relatively high horizontal position, after the refrigerant and the oil-gas mixture enter the first chamber 4, even if oil-gas separation occurs, the lubricating oil will deposit at the lower part of the first chamber 4 of the compressor under the action of gravity, ensuring the oil storage inside the compressor and preventing it from scattering into the system through the suction port. Then, through the second suction through-hole 53 opened at the lower part of the rear housing, it can flow in the lower oil sump of the compressor. Both the gaseous refrigerant and the liquid refrigerant entering the first chamber 4 can only enter the second chamber 9 through the second suction through-hole 53. The flow of the gaseous refrigerant is more likely to stimulate or carry the liquid refrigerant at the bottom of the first chamber 4 to spray onto each component in the second chamber 9, preventing the lubricating oil from accumulating in the dead volume area, and then moving towards the scroll disk on the front side of the compressor, and completing the compression of the refrigerant through the normal operation of the scroll disk. During this process, the refrigerant will bring the oil in the oil sump into the compressor cycle together, enabling the lubricating oil to circulate inside the compressor, preventing excessive lubricating oil from depositing at the bottom of the compressor, and ensuring the normal operation of the mechanical structure.

[0087] The present utility model also provides a new energy vehicle that adopts the above-mentioned horizontal compressor. Through the structural design, the present utility model can impose no excessive restrictions on the direction of the suction port 31. The compressor works normally regardless of the direction of the suction port 31, further relaxing the layout conditions of the compressor in the system, which is particularly beneficial for layout in new energy vehicles with limited space. The rest of the relevant technical features and technical effects are as described above and will not be elaborated here.

[0088] In summary, the horizontal compressor and the new energy vehicle of the present utility model can freely set the direction of the suction port, prevent the lubricating oil from accumulating in the dead volume area, promote all the lubricating oil to participate in the system circulation, and enhance the reliability of the compressor operation.

[0089] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present utility model.
