Abstract:
Disclosed is an oil pump comprising a housing (1), a mounting passage (114), a piston (116) and an elastic member (115). The mounting passage (114) may be formed in the housing (1) defining a first end communicated with a high pressure oil chamber (112) and a sealed second end. The mounting passage (114) may be formed with at least one oil release port (119) and at least one pressure relief port (117) adjacent to the second end for communicating with a low pressure oil chamber (113). The piston (116) may be slidable along the mounting passage (114), and the elastic member (115) may elastically press against the pistion to close the first end. Further, an engine comprising the oil pump and a vehicle comprising the engine are also provided.
Abstract:
A flip device for vehicle-mounted equipment comprises a housing (16), a cover frame (7) mounted onto the top of the housing (16), a mounting bracket (6) for mounting the vehicle-mounted equipment thereon, a slide mechanism (12) disposed within the housing (16), and a power assembly (2) mounted within the housing (16) for driving the sliding mechanism (12) to slide linearly in the housing (16). The mounting bracket (6) is pivotably mounted, at a portion adjacent to a first end thereof, onto the cover frame (7), so that the mounting bracket (6) is rotatable between an extended position in which the mounting bracket (6) is extended out of the cover frame (7) and a folded position in which the mounting bracket (6) is received in the cover frame (7). The slide mechanism (12) is slidable in a longitudinal direction and connected to the mounting bracket (6) so as to drive the mounting bracket (6) to flip between the extended position and the folded position. The flip device can improve the mounting flexibility of the vehicle-mounted equipment and increase the humanization and comfortability of the vehicle.
