It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-Figure 3 As shown, a multi-link liquid booster device provided by an embodiment of the utility model comprises a mounting base 1, a first mounting bracket 5 is connected to the surface of the mounting base 1, and a second support bearing 16 is installed on one side of the first mounting bracket 5, a transmission screw 6 is rotatably connected to the inside of the second support bearing 16, and a moving block 18 is threadedly connected to the outer side of the transmission screw 6, a moving rod 17 is connected to the surface of the moving block 18, and a push block 15 is connected to the end of the moving rod 17 away from the moving block 18, a guide sleeve 7 is arranged inside the first mounting bracket 5, and the moving rod 17 is arranged inside the guide sleeve 7, and preferably, the number of the moving rod 17 and the guide sleeve 7 are both set to two;

[0023] A servo motor 3 is mounted on the surface of the mounting base 1;

[0024] The outer side of the first mounting bracket 5 is connected to the second mounting bracket 8, and the surface of the second mounting bracket 8 is provided with a booster pump body 9, the inside of the booster pump body 9 is provided with a pump cavity, and a plunger rod 13 is movably connected in the pump cavity, and one end of the plunger rod 13 is fixedly connected to the surface of the push block 15, so that when the push block 15 moves, it can pull the plunger rod 13 to move together;

[0025] The surface of the booster pump body 9 is provided with an exhaust port 11, and the inside of the exhaust port 11 is detachably connected with a sealing plug 10. One end of the booster pump body 9 is provided with a liquid inlet and outlet 12, and the liquid inlet and outlet 12 is connected to the pump chamber. By removing the sealing plug 10 from the exhaust port 11, the gas inside the pump chamber can be effectively discharged;

[0026] A sealing ring 14 is provided on one side of the pump chamber of the booster pump body 9, and the plunger rod 13 is penetrated through the inside of the sealing ring 14. The plunger rod 13 is sealed and connected to the booster pump body 9 through the sealing ring 14, so that when the plunger rod 13 moves inside the pump chamber, the liquid medium will not overflow from the inside of the pump chamber.

[0027] In one embodiment of the present invention, the initial position of the moving block 18 is on the left side inside the first mounting bracket 5, that is, most of the area of ​​the plunger rod 13 is drawn out from the pump chamber. At this time, the liquid medium (such as gasoline) to be pressurized flows into the pump chamber through the liquid inlet and outlet 12 and fills the pump chamber.

[0028] When it is necessary to pressurize the liquid medium inside the pump chamber, first turn on the servo motor 3. The output shaft of the servo motor 3 drives the transmission screw 6 to rotate through the second support bearing 16, so that the moving block 18 threadedly connected to the outer side of the transmission screw 6 moves horizontally on the outer side of the transmission screw 6, and the moving block 18 will drive the two moving rods 17 to move inside the two guide sleeves 7, and the two moving rods 17 will drive the pushing block 15 to move, so that the pushing block 15 drives the plunger rod 13 to move inside the pump chamber, and the plunger rod 13 will pressurize the liquid medium inside the pump chamber into the liquid inlet and outlet 12 and discharge it, that is, the plunger rod 13 pressurizes the liquid medium inside the pump chamber.

[0029] Preferably, the first support bearing 4 is installed in an area inside the first mounting bracket 5 away from the second support bearing 16, and the transmission screw 6 is rotatably connected to the inside of the first support bearing 4, so that when the transmission screw 6 rotates, it can obtain the endpoint support of the second support bearing 16 and the axial support of the first support bearing 4, which greatly improves the rotation smoothness of the transmission screw 6.

[0030] Preferably, an elastic coupling 2 is installed on the output end of the servo motor 3, and the transmission screw 6 is linked with the output end of the servo motor 3 through the elastic coupling 2, so as to reduce axial impact, absorb vibration, and compensate for axial, radial and angular deviations, thereby protecting the motor and drive system and extending the service life of the equipment.

[0031] Preferably, an internal fixing thread is provided inside the exhaust port 11, an external fixing thread is provided on the outside of the sealing plug 10, and the sealing plug 10 is detachably connected to the exhaust port 11 through the cooperation of the external fixing thread and the internal fixing thread, so that the staff can more conveniently remove or install the sealing plug 10 inside the exhaust port 11.

[0033] In this embodiment, by sensing the position of the moving block 18 by two position sensors 20, the movement range of the moving block 18 can be limited in real time and accurately, so that the moving block 18 and the plunger rod 13 can accurately return to the initial position, or accurately reach the boost end position, thereby avoiding the problem of motion interference with other structures when the moving block 18 and the plunger rod 13 move during the continuous rotation of the servo motor 3, thereby improving the degree of automation of the multi-link liquid booster device.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
