First embodiment (oil passage of rotating shaft controlled by two shifting blocks)
As shown in fig. 1 to 17, the positive and negative two-way damping mechanism of this embodiment includes a housing 10 having an oil chamber 11, a rotating shaft 20 sealed and rotationally engaged with the oil chamber 11 of the housing 10, at least one baffle 22 fixedly disposed between the housing (10) and the rotating shaft (20) for disturbing damping oil, the baffle 22 separates the oil chamber 11 into at least a first oil chamber and a second oil chamber, and further includes a connecting passage 31a communicating the first oil chamber and the second oil chamber, when the rotating shaft 20 rotates clockwise, the baffle 22 stirs the damping oil in the first oil chamber to make the damping oil in the first oil chamber flow from the connecting passage 31a to the second oil chamber, so that the oil pressure in the first oil chamber is higher than the oil pressure in the second oil chamber, when the rotating shaft 20 rotates counterclockwise, the baffle 22 stirs the damping oil in the second oil chamber to make the damping oil in the second oil chamber flow from the connecting passage 31a to the first oil chamber, so that the oil pressure of the second oil chamber is higher than the oil pressure of the first oil chamber.
In this embodiment, the oil pump further comprises at least one shifting block movably installed between the housing 10 and the rotating shaft 20, and when the rotating shaft 20 rotates clockwise from a starting position, the shifting block actively reduces the through-flow section of one end of the connecting channel 31a under the action of oil pressure, so that the oil pressure of the first oil chamber is higher than that of the second oil chamber; when the rotating shaft 20 rotates counterclockwise from the initial position, the shifting block actively reduces the through-flow cross section of the other end of the connecting channel 31a under the action of oil pressure, so that the oil pressure of the second oil chamber is higher than that of the first oil chamber.
In this embodiment, the oil pump further comprises a first oil passing channel 21 arranged on the rotating shaft 20, and a first open end and a second open end of the first oil passing channel 21 are respectively communicated with the first oil chamber and the second oil chamber; when the rotating shaft 20 rotates clockwise from the initial position, the first opening end of the first oil passing channel 21 passes over the shifting block, and then the shifting block cuts off the communication between the first opening end of the first oil passing channel 21 and the first oil cavity; when the rotating shaft 20 rotates counterclockwise from the initial position, the second open end of the first oil passing channel 21 passes over the shifting block, and then the shifting block cuts off the communication between the second open end of the first oil passing channel 21 and the second oil chamber.
As shown in fig. 7, the first oil passing channel 21 and the baffle 22 are symmetrically disposed on two sides of the axial center of the rotating shaft 20, the first oil passing channel 21 is a chord-direction through groove, the baffle 22 extends in a radial direction, and the first oil passing channel 21 is perpendicular to the baffle 22. Preferably, the first opening end and the second opening end of the first oil passing channel 21 have a size larger than that of the middle channel of the first oil passing channel 21.
As shown in fig. 1 to 3, in the present embodiment, the rotating shaft 20 includes an inner shaft located in the oil chamber 11 in the housing 10 and an outer shaft extending out of the housing 10, and a flange 23 is provided between the inner shaft and the outer shaft; besides the flange 23 of the rotating shaft 20, a gland 40 is provided at a side close to the outer shaft of the rotating shaft, the gland 40 is in sealing connection and matching with the end of the housing 10 through a sealing ring 41 and a gasket 42, and the rotating shaft 20 is in sealing connection with the housing 10 through the gland 40.
As shown in fig. 3, in the present embodiment, the shift blocks include a first shift block and a second shift block; when the rotating shaft 20 rotates clockwise from the initial position, the first shifting block is matched with the rotating shaft 20 so as to reduce the through-flow section of one end of the connecting channel 31 a; when the rotating shaft 20 rotates counterclockwise from the initial position, the second shifting block is matched with the rotating shaft 20 to reduce the through-flow section of the other end of the connecting channel 31 a.
In the present embodiment, as shown in fig. 4 and 5, the dial is a swing-type dial 30a, the inner wall of the housing 10 is provided with a dial mounting seat 12a, one end of the dial is swing-mounted on the dial mounting seat 12a, and the other end of the dial is in clearance fit with the outer peripheral surface of the rotating shaft 20 to form a connecting channel 31 a. Correspondingly, the shifting block mounting seat 12a comprises two symmetrically arranged shifting grooves 121, and the first shifting block and the second shifting block are connected to the shifting grooves 121 in a swinging mode; a first step 122 is arranged between the two shifting grooves 121, second steps 123 are respectively arranged on two sides of the two shifting grooves 121, and the height of each second step 123 is smaller than that of the corresponding first step 122.
The working process of the toilet lid closing process (clockwise rotation of the rotating shaft) of the damping mechanism of the embodiment is briefly described as follows:
as shown in fig. 6 and 7, when the toilet cover is in a fully opened state, for example, the opening angle is 110 °, at this time, in the clockwise rotation process of the rotating shaft 20, the right shifting block in the drawing is the first shifting block, the left shifting block in the drawing is the second shifting block, the first shifting block abuts against and is matched with the circumferential surface of the rotating shaft 20, and the second shifting block is in abdicating and matching with the circumferential surface of the rotating shaft 20;
in the closing process of the toilet cover plate, at the initial stage of clockwise rotation of the rotating shaft 20, the second shifting block yields the first open end of the first oil passing channel 21, and the first shifting block does not close the second open end of the first oil passing channel 21, at this time, the first oil passing channel 21 is in an open state; meanwhile, the baffle 22 on the rotating shaft 20 disturbs the damping oil in the oil cavity 11, the first shifting block is driven to swing through the dynamic pressure of the damping oil, meanwhile, the peripheral surface of the rotating shaft 20 is driven to enable the first shifting block to swing quickly, a connecting channel 31a between the rotating shaft 20 and the shifting block is opened, and at the moment, the oil passing stage is realized quickly;
as shown in fig. 8 and 9, when the rotating shaft 20 continues to rotate clockwise, the first shifting block switches the communication between the second open end of the first oil passing channel 21 and the second oil chamber, so that the first oil passing channel 21 is closed or partially closed; at this time, the damping oil slowly permeates through only a part of the gap of the first oil passage 21 and the connection passage 31a, thereby exerting a damping effect.
As shown in fig. 10 and 11, when the rotating shaft 20 continues to rotate clockwise, the first open end and the second open end of the first oil passing channel 21 are both located in the same oil chamber (low-pressure oil chamber), and the oil passing through the first oil passing channel has no influence on the flow pressure of the damping oil in the oil chamber; at this time, the damping oil is slowly leaked only through the connection passage 31a, thereby exerting a damping effect until the toilet lid is completely closed.
The opening process (the rotating shaft rotates counterclockwise) of the toilet cover is similar to the above process, but only the left shifting block, i.e. the second shifting block, is used, and the description is omitted here.
Second embodiment (oil passage of rotating shaft controlled by a block)

Other embodiments may also adopt that when the rotating shaft 20 rotates clockwise from the initial position, the first end of the shifting block is matched with the rotating shaft 20 so as to reduce the through-flow section of one end of the connecting channel 31 b; when the rotating shaft 20 rotates counterclockwise from the initial position, the second end of the shifting block is matched with the rotating shaft 20 so as to reduce the through-flow section of the other end of the connecting channel 31 b.
As shown in fig. 18 to 19, the shifting block adopts a sliding shifting block 30b, the inner wall of the housing 10 is provided with a limiting rib 12b, one side of the shifting block is a C-shaped surface, and a first end and a second end of the C-shaped surface are respectively abutted and matched with two ends of the limiting rib 12 b; the other side of the shifting block is an arc-shaped surface which is in sliding fit with the peripheral surface of the rotating shaft 20. In this embodiment, the limiting rib 12b and the shifting block are matched to form an arc-shaped surface. The shifting block and the limiting rib 12b are in clearance fit to form a connecting channel 31b, and the through-flow section of one end of the connecting channel is reduced when the first end or the second end of the C-shaped surface is abutted and matched with one end of the limiting rib 12 b.
Other structures and working processes of this embodiment are similar to those of the first embodiment, and are not described herein again.
