Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A hydraulic drive device includes a base plate 101. Fixing holes 102 are provided on both sides of the top end of the base plate 101. Fixing screws 103 are fixedly installed in the fixing holes 102. A hydraulic mechanism 104 is provided on the front side of the top end of the base plate 101, and a drive mechanism 105 is provided on the rear side of the top end of the base plate 101. The hydraulic mechanism 104 includes a first pad 106, which is fixedly installed on the front side of the top end of the base plate 101. A hydraulic chamber 201 is fixedly installed on the top end of the first pad 106. A pump outlet connector 202 is fixedly installed on the top end of the hydraulic chamber 201, and a first solenoid valve 203 is fixedly installed on the pump outlet connector 202.

[0024] The above scheme allows the base plate to be fixed by the fixing screws passing through the fixing holes. The base plate allows for component installation. The first pad blocks support and fix the hydraulic chamber. The first solenoid valve controls the opening and closing of the pump outlet connector. The hydraulic pump connected to the pump outlet connector allows the hydraulic oil in the hydraulic chamber to be pumped out.

[0025] In this embodiment, preferably, the hydraulic mechanism 104 further includes a front cover 204, which is fixedly installed in the middle of the front end of the hydraulic chamber 201. A pump inlet connector 205 is fixedly installed at the front end of the front cover 204, and a second solenoid valve 206 is fixedly installed on the pump inlet connector 205.

[0026] The above solution allows the front end of the hydraulic chamber to be sealed by the front cover, the opening and closing of the pump inlet connector can be controlled by the second solenoid valve, and hydraulic oil can be pumped into the hydraulic chamber by connecting the pump inlet connector to the hydraulic pump.

[0027] In this embodiment, preferably, the driving mechanism 105 includes a second pad 301, which is fixedly installed on the rear side of the top of the base plate 101. A driving box 302 is fixedly installed on the top of the second pad 301, and a sliding box 303 is fixedly installed on the front end of the driving box 302. A sliding cylinder 304 is fixedly installed on the front end of the sliding box 303.

[0028] With the above scheme, the drive box can be supported and installed using the second pad, the drive components can be installed using the drive box, the sliding block can be slid using the sliding box, and the push rod can be slid using the sliding cylinder.

[0029] In this embodiment, preferably, a pusher cylinder 305 is fixedly installed at the front end of the sliding cylinder 304, a rear cover 306 is fixedly installed on the outside of the pusher cylinder 305, the rear cover 306 is fixedly installed at the rear end of the hydraulic chamber 201, a diaphragm 401 is fixedly installed between the rear cover 306 and the rear end of the hydraulic chamber 201, and a pusher plate 402 is fixedly installed in the middle of the diaphragm 401.

[0030] The above scheme allows the pusher plate to be pushed by the pusher cylinder, the rear cover to seal the rear end of the hydraulic chamber, and the pusher plate to be repeatedly pushed inside the pusher cylinder by the oil pressure inside the hydraulic chamber through the diaphragm.

[0031] In this embodiment, preferably, the push plate 402 is movably installed inside the push cylinder 305, a push rod 403 is fixedly installed at the rear end of the push plate 402, the push rod 403 passes through the sliding cylinder 304 and is fixedly installed at the front end of the sliding block 404, the sliding block 404 is movably installed inside the sliding box 303, and first bearings 405 are fixedly installed on both sides of the sliding block 404.

[0032] The above scheme allows the pusher to be repeatedly pushed by the push plate, which in turn causes the push rod to be repeatedly pushed within the sliding cylinder, thereby causing the sliding block to slide repeatedly within the sliding box.

[0033] In this embodiment, preferably, a connecting plate 406 is fixedly installed on the outer side of the first bearing 405, a second bearing 501 is fixedly installed on the rear side of the connecting plate 406, an eccentric disk 502 is fixedly installed in the middle of the second bearing 501, and a drive shaft 503 is fixedly installed on one side of the eccentric disk 502.

[0034] With the above scheme, the connecting plate can be driven to move repeatedly by the sliding block. During the movement, the connecting plate can rotate on the sliding block and the eccentric disk respectively through the first bearing and the second bearing. When the connecting plate rotates on the eccentric disk, it moves repeatedly in coordination with the connecting plate, causing the eccentric disk to move eccentrically on the drive shaft, thereby causing the drive shaft to rotate.

[0035] In this embodiment, preferably, one end of the drive shaft 503 is movably installed inside the drive housing 302, and the other end of the drive shaft 503 is movably installed through the drive housing 302 inside the third bearing 504. The third bearing 504 is fixedly installed inside the bearing cover 505, and the bearing cover 505 is fixedly installed at the left end of the drive housing 302.

[0036] The above solution allows the drive shaft to rotate inside the bearing housing via the third bearing, which in turn protects the third bearing from dust.

[0037] In this embodiment of the hydraulic drive device, when in use, the user connects the pump inlet connector 205 and the pump outlet connector 202 to the hydraulic pump respectively. When the hydraulic pump operates and pumps hydraulic oil into the pump inlet connector 205, the first solenoid valve 203 controls the pump outlet connector 202 to close and the second solenoid valve 206 controls the pump inlet connector 205 to open, allowing the hydraulic oil to be pumped into the hydraulic chamber 201. After the hydraulic oil is pumped in, the oil pressure in the hydraulic chamber 201 increases. Subsequently, the oil pressure pushes the diaphragm 401, causing the diaphragm 401 to push the push plate 402 within the push cylinder 305. After the push plate 402 is pushed, the hydraulic pump connected to the pump outlet connector 202 immediately pumps the hydraulic oil out through the pump outlet connector 202. The first solenoid valve 203 controls the opening of the pump outlet connector 202, and the second solenoid valve 206 controls the closing of the pump inlet connector 205, causing hydraulic oil to be pumped out of the hydraulic chamber 201, thus reducing the oil pressure inside the hydraulic chamber 201. After the pressure drops, the diaphragm 401 is pulled out of the push cylinder 305 by the negative pressure, causing the push plate 402 to be driven back to its original position. When the first solenoid valve 203 and the second solenoid valve 206 control the opening and closing of the hydraulic chamber 201 in conjunction with the hydraulic pump to repeatedly raise and lower the oil pressure inside the hydraulic chamber 201, the push plate 402 can be driven by the diaphragm 401 to generate repeated pushing. Therefore, the push rod 403 drives the sliding block 404 to slide repeatedly within the sliding box 303. When the sliding block 404 slides, it drives the connecting... The connecting plate 406 moves back and forth. When the connecting plate 406 moves, the rotation of the first bearing 405 and the second bearing 501 causes the eccentric disk 502 to move eccentrically on the drive shaft 503. This eccentric movement of the eccentric disk 502 causes the drive shaft 503 to rotate within the drive chamber and the third bearing 504. Under the action of the hydraulic chamber 201, the connecting rod formed by the push plate 402 and the push rod 403 continuously extends and retracts, causing the eccentric disk 502 to rotate continuously, thereby driving the drive shaft 503 to rotate. The driving force generated by the drive shaft 503 can be used for the rotation needs of various mechanical operations, such as automobiles. Furthermore, when the drive shaft 503 is directly driven by the drive device... During operation, the pump inlet connector 205 is connected to the hydraulic oil tank and its opening and closing are controlled by the first solenoid valve 203, and the pump outlet connector 202 is connected to the device requiring oil intake and its opening and closing are controlled by the second solenoid valve 206. When the drive shaft 503 drives the push assembly forward, the diaphragm 401 is pushed into the hydraulic chamber 201 by the push plate, which pushes the hydraulic oil and increases the oil pressure in the hydraulic chamber 201, so that the hydraulic oil can be discharged through the pump outlet connector 202. When the push assembly is reset, the diaphragm 401 is brought back into the push cylinder 305, which makes the hydraulic chamber 201 negative pressure, so that the pump inlet connector 205 can draw the hydraulic oil in the hydraulic oil tank into the hydraulic chamber 201. Through repeated pushing, the hydraulic oil can be pumped.
