Embodiment Construction

[0018] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0019] Such as Figure 1~3 As shown, the present invention includes a frame 15, a compression cylinder, a drive arm, a drive wheel 1 and a linear stepper motor A12, wherein the compression cylinder includes a cylinder body 8, a piston 7, a piston rod 6, an auxiliary piston 9, and a support rod 10, wherein The piston rod 6 is rotationally connected with the piston 9, and the auxiliary piston 9 and the piston 7 are installed in the cylinder body 8 in turn. A cylindrical leak-proof cavity is also arranged at the closed end of the cylinder body 8. Between the cylinder body 8 and the leak-proof space The middle part of the closed end is provided with a through hol...

Abstract

The invention relates to a compressor with variable compression amount. The compressor comprises a rack, a driving arm, a driving wheel, a first linear driving mechanism, a cylinder body, a piston and a piston rod, wherein the closed end of the cylinder body is also provided with an auxiliary piston, the auxiliary piston is connected with a supporting rod, the supporting rod is connected with the first linear driving mechanism through an opening, the auxiliary piston moves in the cylinder body under the driving of the first linear driving mechanism, the driving arm comprises a connecting rod A, a connecting rod B and a second linear driving mechanism, and the driving wheel and the driving arm are both connected with a main rotating shaft in a rotating manner. The compression amount of the compressor is changed in a manner that the included angle of the connecting rod A and the connecting rod B and the volume of the cylinder body are changed by the second linear driving mechanism. Thus, the volume of the compressing cylinder and the moving stroke of the piston are changed through two groups of linear driving mechanisms, and the compression amount of the compressor is adjusted through changing the two parameters, so that the structure is simple and stable.

Description

technical field [0001] The invention relates to a compressor with variable compression capacity, which belongs to the field of air-conditioning compressors in vehicle-mounted equipment. Background technique [0002] Common car air conditioner compressors include crankshaft connecting rod compressors, axial piston compressors, rotary vane compressors, and scroll compressors. Among them, crankshaft connecting rod compressors are widely used, with mature manufacturing technology and simple structure. , and have lower requirements on processing materials and processing technology, and lower cost; strong adaptability, can adapt to a wide range of pressure and cooling capacity requirements, and strong maintainability, but this crankshaft-connecting rod compressor has compression capacity The disadvantage that cannot be changed, if you want to change the cooling capacity, you can only change it by changing the exhaust pressure of the valve. This change method also causes a relative...
