Abstract: A cover plate assembly, a stator, an electric motor, a compressor and a vehicle are provided. The cover plate assembly is used for the electric motor having a lead. The cover plate assembly has a first housing and a second housing. The first housing has a first passage portion. The second housing is detachably connected to the first housing. A sealing cavity and a second passage portion are jointly enclosed between the first housing and the second housing. The first passage portion and the second passage portion are both in communication with the sealing cavity. The lead of the electric motor extends into the sealing cavity through the second passage portion.

Abstract: Provided are a scroll compressor, a refrigeration device, and a vehicle. In the scroll compressor, an oil discharging hole of an oil separation structure and an oil storage tank are connected to each other by an oil outlet channel disposed in a housing, and an oil outlet of the oil outlet channel is located above an oil inlet. The oil outlet channel can guide a refrigeration oil discharged from the oil discharging hole to flow into the oil storage tank. After passing through the oil outlet channel, a flow rate and a pressure of the refrigeration oil decrease, and thus an impact of the refrigeration oil on the remaining refrigeration oil in the oil storage tank is reduced when discharged from the oil outlet. Therefore, the refrigeration oil within the oil storage tank remains stable and can always immerse an oil return hole of the oil storage tank.

Abstract: A compressor (100) and a vehicle are disclosed. The compressor (100) includes: a housing (1); a separating component (2) dividing an interior of the housing (1) into a low-pressure chamber (13) and a high-pressure chamber (14); a cylinder component (3); a crankshaft (4); a plurality of oil transmission grooves (5); and at least one oil transition groove (6). During the rotation of the crankshaft (4), each oil transition groove (6) is intermittently in communication with oil transmission grooves (5) adjacent thereto. The oil transition groove (6) is alternately in communication with two oil transmission grooves (5) located at two circumferential sides of the oil transition groove (6). An oil-way passage (31) of the cylinder component (3) is in communication with one of oil transmission grooves (5), and another one of oil transmission grooves (5) or the oil transition groove (6) is in communication with the low-pressure chamber (13).

Abstract: A crankshaft for a rotary compressor includes: a body (1) and an eccentric portion (2), the eccentric portion (2) being fitted over the body (1), wherein at least one of a flexible structure (21) and an oil pressure surface (22) is arranged on the eccentric portion (2). The flexible structure (21) is configured to deform inwards when subject to an external force in an inward direction. The oil pressure surface (22) is configured in such a way that in a direction opposite to a rotating direction of a rotating central axis of a crankshaft (300), a distance between a front end (221) of the oil pressure surface (22) and the central axis of the eccentric portion (2) is smaller than a distance between a tail end (222) of the oil pressure surface (22) and the central axis of the eccentric portion (2). Also disclosed are a rotary compressor and a refrigerating cycle device.
