The spring can absorb the energy generated by the vibration during the lifting of the car, making the lifting process more stable. At the same time, the damper can keep the lift in a more stable state during the lifting process. The rubber sleeve is sleeved on the outer surface of the fixed column, which improves the stability of the connection between the block and the base. At the same time, the rubber sleeve itself has excellent elasticity and damping performance, which can effectively absorb and relieve vibration and impact, thereby reducing the impact force on the base during the lifting of the car and increasing the service life of the base.

[0020] 2. When the sensor senses that there is no contact with the extension rod, the hydraulic rod starts to drive the sensor upward. When the sensor senses that there is contact with the extension rod, the hydraulic rod stops moving.

[0028] In this technical solution, the device is placed at the bottom of the vehicle when in use, and the height of the vehicle is lifted by the lifting mechanism 2. The spring 5 can absorb the energy generated by the vibration generated during the lifting of the car, making the lifting process more stable. At the same time, the damper 6 can keep the lift in a more stable state during the lifting process. The rubber sleeve 9 is sleeved on the outer surface of the fixed column 4, which improves the stability of the connection between the block 3 and the base 7. At the same time, the rubber sleeve 9 itself has excellent elasticity and damping performance, which can effectively absorb and alleviate vibration and impact, thereby reducing the impact force on the base 7 during the lifting of the car and improving the service life of the base 7.

[0029] In some technical solutions, such as Figure 1-2As shown, a connecting plate 10 is fixedly installed between two groups of adjacent sleeves 1, a motor frame 11 is fixedly installed on the top of the connecting plate 10, and the lifting mechanism 2 includes a double-headed motor 201, and the double-headed motor 201 is fixedly installed on the top of the motor frame 11, and two groups of output ends of the double-headed motor 201 are fixedly installed with screws 202, and the end of the screw 202 away from the sleeve 1 is rotatably connected to the side wall of the sleeve 1, and the outer surface of the screw 202 is threadedly connected with an adjustment block 203, and the inside of the sleeve 1 is slidably connected with an extension rod 204, and the top of the four groups of extension rods 204 are fixedly installed with a support platform 205, and the bottom end of the support platform 205 is fixedly installed with a fixed block 206, and the fixed block 206 is hinged with an adjustment rod 207 between the adjustment block 203.

[0030] When in use, the vehicle is placed on the top of the support platform 205, and the two sets of screw rods 202 are driven to rotate by the double-headed motor 201. Since the threads of the two sets of screw rods 202 on both sides of the double-headed motor 201 are in opposite directions, the two sets of adjustment blocks 203 are close to each other, thereby driving the adjustment rod 207 to lift the support platform 205. The adjustment rod 207 links the four sets of extension rods 204 to slide and rise synchronously in the corresponding sleeves 1, thereby achieving the lifting effect.

[0031] In some technical solutions, such as Figure 1 As shown, a hydraulic rod 13 is fixedly installed inside the sleeve 1 , a sensor 14 is fixedly installed on the top end of the hydraulic rod 13 , and the top end of the sensor 14 is fixedly installed on the bottom end of the extension rod 204 .

[0032] During use, when the sensor 14 senses that there is no contact with the extension rod 204, the hydraulic rod 13 starts to drive the sensor 14 to move upward. When the sensor 14 senses that there is contact with the extension rod 204, the hydraulic rod 13 stops moving. At this time, the hydraulic rod 13 supports the sensor 14, preventing the extension rod 204 from slipping, thereby improving the safety of this device during the vehicle lifting process.

[0033] In some technical solutions, such as Figure 2 As shown, a weighted seat 15 is fixedly installed at the bottom end of the block 3 , and an anti-skid pad 16 is fixedly installed at the bottom end of the weighted seat 15 .

[0034] When in use, the weighted seat 15 improves the stability of the device when placed, and the anti-skid pad 16 further improves the stability of the device when placed.

[0035] In some technical solutions, such as Figure 1 As shown, a T-shaped guide rod 17 is fixedly installed at the bottom end of the adjusting block 203 , and a sliding groove 18 matching the adjusting block 203 is opened inside the connecting plate 10 .

[0036] When in use, the T-shaped guide rod 17 slides in the slide groove 18 when the adjusting block 203 moves. At the same time, the T-shaped guide rod 17 guides the adjusting block 203 when it moves, thereby improving the guiding performance of the adjusting block 203 when it moves.

[0037] In some technical solutions, such as Figure 1 As shown, a switch 19 is fixedly mounted on one side of one set of sleeves 1 .

[0038] When in use, the switch 19 facilitates the user to use the device, thereby improving the practicability of the device.

[0039] Working principle: When in use, the device is placed at the bottom of the vehicle, and the height of the vehicle is lifted by the lifting mechanism 2. The spring 5 can absorb the energy generated by the vibrations during the lifting of the car, making the lifting process smoother. At the same time, the damper 6 can keep the lift in a more stable state during the lifting process. The rubber sleeve 9 is sleeved on the outer surface of the fixed column 4, which improves the stability of the connection between the block 3 and the base 7. At the same time, the rubber sleeve 9 itself has excellent elasticity and damping performance, which can effectively absorb and alleviate vibrations and impacts, thereby reducing the impact force on the base 7 during the lifting of the car and increasing the service life of the base 7. When in use, the vehicle is placed on the top of the support platform 205, and the two sets of screws 202 are driven to rotate by the double-headed motor 201. Since the threads of the two sets of screws 202 on both sides of the double-headed motor 201 are in opposite directions, the two sets of adjustment blocks 203 are close to each other, thereby driving the adjustment rod 207 to lift the support platform 205. The adjusting rod 207 links the four groups of extension rods 204 to slide and rise synchronously in the corresponding sleeves 1, thereby achieving the lifting effect. When the sensor 14 senses that there is no contact with the extension rod 204, the hydraulic rod 13 starts to drive the sensor 14 to move up. When the sensor 14 senses that it is in contact with the extension rod 204, the hydraulic rod 13 stops moving. At this time, the hydraulic rod 13 supports the sensor 14 to prevent the extension rod 204 from slipping, thereby improving the safety of the device during vehicle lifting. The weighted seat 15 improves the stability of the device when placed, and the anti-slip pad 16 further improves the stability of the device when placed. When the adjusting block 203 moves, the T-shaped guide rod 17 is linked to slide in the slide groove 18. At the same time, the T-shaped guide rod 17 guides the adjusting block 203 when it moves, thereby improving the guidance of the adjusting block 203 when it moves. The switch 19 is convenient for users to use the device, thereby improving the practicality of the device when used.
