Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The extrusion mechanism 4 provided on the adjustment mechanism 3 includes two cylinders 43 symmetrically provided on the extrusion mechanism 4 ; two extrusion blocks 44 , respectively provided at the output ends of the two cylinders 43 , for extruding the lifting torsion spring.

[0041] In this embodiment, the utility model provides an assembly device for a car seat cushion lifting torsion spring, wherein a car seat cushion frame to be assembled with a lifting torsion spring is placed on a load-bearing body 1, and a limiting mechanism 2 limits the car seat cushion frame placed on the load-bearing body 1, thereby preventing the car seat cushion frame from moving when the car seat cushion is assembled with the lifting torsion spring, and then the position of the extrusion mechanism 4 can be adjusted by the adjustment mechanism 3, so that the extrusion mechanism 4 can assemble lifting torsion springs for car seat cushions of different specifications, and the extrusion block 44 provided on the extrusion mechanism 4 will squeeze the lifting torsion spring placed on the car seat cushion frame, thereby making it more convenient for the staff to install the lifting pump, thereby avoiding the need to manually squeeze the lifting torsion spring and then install the lifting pump, thereby improving the installation efficiency of the lifting torsion spring and improving the personal safety of the staff.

[0042] More details, such as Figure 1 As shown, the upper end surface of the carrier body 1 in the preferred embodiment of the present invention is provided with a clearance hole 11 ; the placement hole 12 is also provided on the upper end surface of the carrier body 1 .

[0043] Preferably, there are two relief holes 11 , which are symmetrically opened on the upper end surface of the supporting body 1 .

[0044] Further, such as Figure 2 As shown, the limiting mechanism 2 in the preferred embodiment of the present invention includes a guide rod 21, which is arranged on the lower end surface of the carrying body 1; a mounting plate 22, which is arranged on the lower end surface of the guide rod 21; a servo motor 23, which is arranged on the lower end surface of the mounting plate 22; a screw rod 24, which is arranged on the output end of the servo motor 23; a movable plate 25, which is arranged on the outer side of the screw rod 24; two connecting rods 26, which are arranged on the movable plate 25, and the two connecting rods 26 are respectively located in the clearance holes 11; two limiting plates 27, which are respectively arranged on the upper end surfaces of the two connecting rods 26, for limiting the car seat cushion frame.

[0045] Furthermore, the inner side of the movable plate 25 is threadedly connected to the outer side of the screw rod 24 , and the movable plate 25 can also be slidably disposed on the outer side of the guide rod 21 .

[0046] In this embodiment, multiple preferred embodiments of the limiting mechanism 2 are given. The servo motor 23 drives the screw rod 24 to rotate, and the rotating screw rod 24 drives the movable plate 25 to move downward, so that the connecting rod 26 on the upper end surface of the movable plate 25 drives the limiting plate 27 to move downward, so that the limiting plate 27 limits the car seat frame placed on the supporting body 1, ensuring the stability of the car seat frame when installing the lifting torsion spring.

[0047] Further, such as Figure 3 As shown, the adjustment mechanism 3 in the preferred embodiment of the present invention includes four mounting rods 31, which are evenly arranged on the lower end surface of the carrying body 1; a connecting plate 32, which is arranged between the lower end surfaces of the four mounting rods 31; two electric push rods 33, which are symmetrically arranged on the lower end surface of the connecting plate 32; a fixing plate 34, which is arranged between the output ends of the two electric push rods 33, and the fixing plate 34 is located in the placement hole 12 for the installation of the extrusion mechanism 4.

[0048] In this embodiment, multiple preferred embodiments of the adjustment mechanism 3 are given. The electric push rod 33 can drive the fixing plate 34 to move up and down, thereby adjusting the position of the extrusion mechanism 4, so that the extrusion mechanism 4 and the position where the lifting torsion spring needs to be installed on the car seat cushion frame placed on the supporting body 1 are aligned, so that the extrusion mechanism 4 can better extrude the lifting torsion spring. Since the electric push rod 33 is arranged on the connecting plate 32, the extrusion mechanism 4 has a wider adjustable range.

[0049] Further, such as Figure 4 As shown, an extrusion mechanism 4 in a preferred embodiment of the present invention is provided, which includes a hydraulic rod 41, which is arranged on the outside of the fixed plate 34; a connecting sleeve 42, which is arranged at the output end of the hydraulic rod 41, and two cylinders 43 are symmetrically arranged on the outside of the connecting sleeve 42 along the hydraulic rod 41; a sliding groove 45, which is opened on the outside of the connecting sleeve 42; two sliding blocks 46, which are respectively arranged on one side of the extrusion block 44 close to the hydraulic rod 41, for improving the stability of the extrusion block 44.

[0050] In more detail, the sliding block 46 is slidably disposed in the sliding groove 45 , and a side surface of the sliding block 46 close to the hydraulic rod 41 contacts the inner side of the sliding groove 45 .

[0051] In this embodiment, multiple preferred implementations of the extrusion mechanism 4 are given, and the extrusion block 44 is driven to move by the cylinder 43. In this way, the distance between the two extrusion blocks 44 can be adjusted by the specifications of the lifting torsion spring, ensuring that the extrusion block 44 can better extrude the lifting torsion spring. The hydraulic rod 41 drives the connecting sleeve 42 to move, so that the two extrusion blocks 44 extrude the lifting torsion spring placed on the car seat cushion frame, thereby facilitating the installation of the lifting pump by the staff. At the same time, when the extrusion block 44 extrude the lifting torsion spring, the sliding block 46 provided on the extrusion block 44 can improve the stability of the extrusion block 44, thereby avoiding displacement of the extrusion block 44 provided at the output end of the cylinder 43 during extrusion.
