Embodiment 2

[0044] In the scroll compressor of the second embodiment, the setting method of the positioning pin 60 is changed, such as Figure 4 and Figure 5 As shown, in this embodiment, when a positioning pin 60 is arranged between the fixed scroll 40 and the support 20 , the fixed scroll 40 can float along the axial direction of the support 20 . At the same time, there is a preset gap H2 between the fixed scroll 40 and the casing 10, and the preset gap H2 satisfies: 0

Embodiment 3

[0045] The scroll compressor of the third embodiment changes the drainage mode of the back pressure chamber, such as Figure 6 As shown, the movable scroll 30 has a communication passage 31, the communication passage 31 communicates with the medium pressure chamber and the medium pressure passage 42, and the compression chamber at the intermediate pressure passes through the communication passage 31 on the movable scroll 30 and the fixed scroll 40 The medium pressure channel 42 on the top communicates with the back pressure chamber to provide pressure for the back pressure chamber. To facilitate processing, such as Figure 7 As shown, the communication channel 31 of this embodiment includes a first section 311 and a second section 312 arranged axially and a third section 313 arranged radially, and the third section 313 communicates with the first section 311 and the second section 312 .

[0046] Such as Figure 7 As shown, the fixed scroll 40 of this embodiment is provided ...

Embodiment 4

[0047] In the scroll compressor of Embodiment 4, the drainage mode of the back pressure chamber is changed, such as Figure 8 As shown, the second rib 54 of this embodiment is provided with a throttling passage 55 connecting the exhaust chamber and the medium-pressure chamber, and the pressure of the refrigerant drops slightly after entering the middle-pressure chamber through the throttling passage 55 . The fixed scroll 40 also includes a pressure regulating valve 44 . The pressure regulating valve 44 communicates with the intermediate pressure chamber and the intake chamber, that is, the pressure in the intermediate pressure chamber is equivalent to the sum of the suction pressure and the spring force of the pressure regulating valve 44 . The suction pressure is different under different working conditions. Correspondingly, the pressure of the intermediate pressure chamber can be automatically adjusted so that the pressure difference on the fixed scroll 40 is within a preset ...

Abstract

The invention provides a scroll compressor and a vehicle provided with same. The scroll compressor comprises a base body, a movable scroll plate, a static scroll plate and an end cover, wherein the base body is provided with an opening; the movable scroll plate is rotatably arranged on the base body; the static scroll plate can be arranged on the base body in a floating mode in the axial directionof the base body; a compression cavity is formed between the static scroll plate and the movable scroll plate; the end cover is arranged in the opening of the base body; and a sealed back pressure cavity is formed between the end cover and the static scroll plate. The technical scheme effectively solves the problem that a scroll compressor in the prior art is complex in structure and is troublesome in assembly.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll compressor and a vehicle with the same. Background technique [0002] At present, the refrigerant used in conventional new energy vehicles is R134A, and the heating uses PTC auxiliary heating, which has low efficiency and affects its battery life. In order to further increase the heating capacity in winter without increasing the volume of the compressor, refrigerants such as R410A have been tried to use, but while increasing the unit cooling capacity of this refrigerant, the corresponding saturation pressure has also been greatly increased. Hermeticity poses a challenge. U.S. Patent US6872063, the back pressure is in the floating form of the moving plate, the elastic sheet is sealed with the moving plate and the bracket through elastic deformation, and at the same time, the bracket is sealed with the crankshaft through the shaft seal to form a back pressure chamber. The pres...
