Technical Field

[0001] The utility model relates to the technical field of electric compressors, in particular to an ultra-low temperature heat pump type electric compressor. Background Art

[0002] The automotive electric compressor is the core component of the air-conditioning system of new energy vehicles. The electric compressor is usually composed of an electric motor, a compressor, a clutch and a control system. The electric motor drives the compressor to compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure liquid refrigerant, and transports it to the evaporator through a pipeline for heat exchange. The clutch is used to control the start and stop of the compressor to save energy, and the control system is used to adjust the speed and power of the compressor to meet different refrigeration needs. It can provide refrigeration function without the need for the engine to run, thereby improving the vehicle's energy utilization efficiency and environmental protection performance. Its advantages are high efficiency, low noise, high reliability, and can provide stable refrigeration effects under different working conditions.

[0003] There are generally two ways to arrange the electric compressor of existing new energy vehicles. One is to connect the electric compressor to the front motor through a rigid bracket, and the other is to connect the electric compressor to the front cabin chassis or body parts through a bracket.

[0004] When the electric compressor is installed on the side of the vehicle body through the bracket, the electric compressor and the bracket are horizontally distributed. Due to the small installation space, the alignment of the holes of the electric compressor and the bracket cannot be determined, which is inconvenient during maintenance and disassembly. Based on this, an ultra-low temperature heat pump electric compressor is provided. Utility Model Content

[0011] As a further solution of the utility model: the lateral part of the bottom of the C-shaped fixing frame and the side of the rubber support pad are misaligned with the side of the bottom fixing column away from the adapter mounting frame.

[0012] As a further solution of the utility model: a heat dissipation through hole is opened in the middle of the adapter mounting frame to reduce heat dissipation shielding to the compressor casing body.

[0013] As a further solution of the utility model: the C-shaped fixing frame is provided with mounting holes, and the distribution area of ​​the mounting holes is aligned with the heat dissipation through holes in the horizontal direction.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 3 In an embodiment of the utility model, an ultra-low temperature heat pump type electric compressor includes an electric compressor 1 composed of a compressor casing body 101, a top fixed cylinder 102, and a bottom fixed cylinder 103. The top fixed cylinder 102 is fixed to the top of the compressor casing body 101, and the bottom fixed cylinder 103 is fixed to the bottom of the compressor casing body 101. There are two bottom fixed cylinders 103, and the two bottom fixed cylinders 103 are symmetrically distributed with the top fixed cylinder 102 as the center. A mounting support 2 is provided on one side of the electric compressor 1, and the mounting support 2 is used to provide mounting support for the electric compressor 1;

[0023] The mounting support 2 includes a C-shaped fixing frame 201, an adapting mounting frame 202, a rubber supporting pad 203, and a docking groove 207;

[0024] The adapter mounting frame 202 is fixed to the top of the bottom transverse part of the C-shaped fixing frame 201 and is fixedly connected to the side of the top transverse part of the C-shaped fixing frame 201. The rubber support pad 203 is fixed to the top of the bottom transverse part of the C-shaped fixing frame 201 and is distributed on the side of the adapter mounting frame 202 away from the C-shaped fixing frame 201.

[0025] The docking groove 207 is symmetrically opened on the top of the rubber support pad 203, and the side of the adapter mounting frame 202 is opened with a threaded hole 205 matching the top fixing column 102 and the bottom fixing column 103;

[0026] The compressor casing body 101 is clamped to the inner side of the docking groove 207 through the bottom fixed column 103, so as to realize the automatic alignment operation between the top fixed column 102, the side of the bottom fixed column 103 and the threaded hole 205;

[0027] A heat dissipation through hole 206 is provided in the middle of the adapter mounting frame 202 to reduce heat dissipation shielding to the compressor casing body 101;

[0028] The C-shaped fixing frame 201 is provided with mounting holes 204 , and the distribution area of ​​the mounting holes 204 is aligned with the heat dissipation holes 206 in the horizontal direction.

[0029] In this embodiment: when installing the electric compressor 1, the entire mounting support 2 can be fixed to the side of the frame by screws penetrating the mounting hole 204, and then the electric compressor 1 is placed downward on the rubber support pad 203 as a whole, and the bottom fixed cylinder 103 is engaged with the corresponding docking groove 207. At this time, the top fixed cylinder 102, the bottom fixed cylinder 103 and the threaded hole 205 are aligned in the horizontal direction, and then the electric compressor 1 is pushed horizontally to make it fit on the adapter mounting frame 202, and finally the top fixed cylinder 102, the bottom fixed cylinder 103 are penetrated by bolts and screwed into the threaded hole 205;

[0030] The coordination of the above-mentioned multiple parts can realize efficient installation of the electric compressor 1. During the installation process, there is no need to judge the alignment of the top fixed column 102, the bottom fixed column 103 and the threaded hole 205 by naked eyes, that is, it will not be affected by the narrow space. Compared with the traditional installation alignment operation, the overall operation is more convenient and efficient.

[0032] The sides of the top fixed column 102 and the bottom fixed column 103 close to the adapter mounting frame 202 are displaced in the horizontal direction, and the side of the bottom fixed column 103 away from the adapter mounting frame 202 protrudes from the side of the outer wall of the compressor casing body 101.

[0033] In this embodiment, the C-shaped fixing frame 201 and the rubber support pad 203 are staggered with the side of the bottom fixing column 103 away from the side of the adapter mounting frame 202, so that the C-shaped fixing frame 201 and the rubber support pad 203 will not affect the tightening operation of the bolts inside the bottom fixing column 103;

[0034] The top fixing column 102 and the bottom fixing column 103 are staggered in the horizontal direction near the side of the adapter mounting frame 202, so that the bolt force points at the upper and lower ends of the electric compressor 1 are staggered, thereby further enhancing the overall vertical shear strength of the multiple bolts;

[0035] Since one side of the bottom fixing column 103 away from the adapter mounting frame 202 protrudes from the outer wall side of the compressor casing body 101, maintenance personnel can easily observe the bolts inside the bottom fixing column 103 to facilitate disassembly and installation of the bolts.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
