When the first valve body 201 and the second valve body 202 are both opened, the flowing medium can sequentially flow through an oil outlet of the oil pump 207, the first valve body 201, the execution cylinder 206, the second valve body 202 and an oil return port of the oil pump 207 to form a main loop; when the first valve body 201 is closed and the second valve body 202 is opened, the flowing medium flows through the oil outlet of the oil pump 207, the oil inlet of the auxiliary oil tank 210, the oil outlet of the auxiliary oil tank 210 and the oil return port of the oil pump 207 in sequence to form an auxiliary loop; when the first valve body 201 is opened and the second valve body 202 is closed, the flowing medium flows through the oil outlet of the auxiliary oil tank 210, the oil return port of the oil pump 207, the oil outlet of the oil pump 207, the first valve body 201 and the actuating cylinder 206 in sequence to form an auxiliary oil path.

The second valve body 202 is further provided with a check valve 205 to restrict the flow of the flowing medium in the oil pump 207 or the auxiliary oil tank 210 from directly flowing to the second valve body 202.
For the mobile device requiring shock absorption, the actuator in this embodiment is connected to the mechanism for carrying people on the mobile device, the cylinder 206 is connected to the mechanism for contacting the mobile device with the ground, and the sensing housing 221 is fixedly connected to the mechanism for contacting the mobile device with the ground. For example, in the case of a passenger vehicle, the shock absorbing device in the present embodiment serves as a suspension structure in the vehicle.
Normally, the shock absorption is mainly realized by the electronic control balance assembly 100. When the electronic control balance assembly 100 fails due to a fault or the electronic control balance assembly 100 is manually closed to avoid the electronic control balance assembly 100 from being damaged due to a bad working condition, the mechanical balance assembly 200 has a shock absorption function.
When the mobile device is in a stationary state, as shown in fig. 3, the surface of the flowing medium in the sensing housing 221 is always kept horizontal, so the sensing plate 222 is also always in a horizontal state, the first valve body 201 and the second valve body 202 connected to the connecting shaft are both in a conducting state, and the hydraulic circuit is in a main circuit state, and damping is performed only by means of the hydraulic performance of the actuating cylinder 206. Meanwhile, the pressure in the main circuit does not reach the preset value, and the first pressure valve 203 and the second pressure valve 204 are closed. The partition 211 in the auxiliary tank is in the middle position and a certain amount of flowing medium is stored in the oil storage cavity.
When the mobile device is in a downhill state with a lower front end and a higher rear end, as shown in fig. 4, the surface of the flowing medium in the sensing housing 221 is always kept horizontal, so the sensing plate 222 is also always horizontal, and the sensing housing 221 rotates along with the mobile device, i.e., the sensing plate 222 and the sensing housing 221 rotate relatively, so as to drive the connecting shaft to rotate, so that the first valve body 201, which is originally in a conducting state, is closed, and the second valve body 202 is still opened. The oil pump 207 continuously drives the flowing medium to flow out of the execution cylinder 206, and the flowing medium flowing out of the oil outlet of the oil pump 207 cannot flow back into the execution cylinder 206 through the first valve body 201 due to the closed state of the first pressure valve 203, so that the flowing medium in the execution cylinder 206 is reduced, the piston rod of the execution cylinder 206 is lowered, the rear end of the mobile equipment is lowered, and the mobile equipment is kept in a horizontal state as much as possible.
And the flowing medium flowing out from the oil outlet of the oil pump 207 is stored in a pipeline between the oil outlet of the oil pump 207 and the first valve body 201 and the first pressure valve 203, the pressure in the pipeline continuously rises until a preset value is reached, the first pressure valve 203 is opened, the flowing medium enters an oil storage cavity in the auxiliary oil tank 210, the increase of the flowing medium drives the partition plate 211 to move upwards and the oil storage cavity is continuously increased until the partition plate 211 cannot move to the upper limit position, and the oil storage cavity is not increased any more. As the flowing medium continues to increase, the pressure in the oil storage cavity continues to rise until the second pressure valve 204 is opened, the flowing medium flows out of the oil outlet of the auxiliary oil tank 210, and the hydraulic circuit enters an auxiliary circuit state.
When the mobile device returns to the horizontal state again, the sensing plate 222 rotates reversely relative to the sensing housing 221, and returns to the initial state again, and at this time, the first valve body 201 and the second valve body 202 are both conducted. The high pressure hydraulic oil in the circuit near the oil pump 207 flows to a low pressure near the actuator cylinder 206 until the pressures in the circuit are equal. In this process, the first pressure valve 203 and the second pressure valve 204 are successively closed. Thereby, the entire apparatus is returned to the initial state.
When the mobile device is in an ascending state with a higher front end and a lower rear end, as shown in fig. 5, the surface of the flowing medium in the sensing shell 221 is always kept horizontal, so the sensing plate 222 is also always in a horizontal state, and the sensing shell 221 rotates along with the mobile device, that is, the sensing plate 222 and the sensing shell 221 rotate relatively, so as to drive the connecting shaft to rotate, so that the second valve body 202 which is originally in a conducting state is closed, and the first valve body 201 is still opened. Because the second valve body 202 is closed, the oil pump 207 cannot pump out flowing medium from the execution cylinder 206, negative pressure is formed in the section of the pipeline from the execution cylinder 206 to the oil return port of the oil pump 207, when the negative pressure reaches a preset value, the second pressure valve 204 is opened, the flowing medium in the oil storage cavity is pumped out by the oil pump 207 under the action of the negative pressure and flows into the execution cylinder 206, the flowing medium in the execution cylinder 206 is increased, the piston rod of the execution cylinder 206 is lifted, the rear end of the mobile equipment is lifted, and therefore the mobile equipment is kept in a horizontal state as far as possible.
When the mobile device returns to the horizontal state again, the sensing plate 222 rotates reversely relative to the sensing housing 221, and returns to the initial state again, and at this time, the first valve body 201 and the second valve body 202 are both conducted. The high pressure hydraulic oil in the circuit near the actuator cylinder 206 flows to a low pressure near the oil pump 207 until the pressures in the circuits are equal. In this process, the first pressure valve 203 and the second pressure valve 204 are successively closed. Thereby, the entire apparatus is returned to the initial state.
In addition, two inertia blocks 223 are disposed in the sensing shell 221, and the two inertia blocks 223 are respectively disposed at two opposite ends of the sensing shell 221 and are connected to the sensing shell 221 through an elastic member. In the initial state, neither inertia block 223 interferes with the rotation of the sensing plate 222. When the mobile device makes an acceleration motion, the inertia block 223 at the front side moves backward relative to the induction shell 221 under the inertia effect and blocks the induction plate 222 from rotating; when the mobile device performs a deceleration motion, the inertia block 223 at the rear side moves forward relative to the sensing housing 221 by inertia and blocks the sensing plate 222 from rotating. Therefore, the interference caused by the change of the flowing medium due to the acceleration and deceleration movement of the mobile equipment can be eliminated.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the present invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
