In terms of a seat for a transport vehicle, the seat adjustment mechanism 100 of the present invention is preferably installed on one side of a seat cushion (not shown in the figure) for adjusting the height of the seat cushion, wherein the seat cushion is also connected to a Chair back (not pictured).

The cover plate 110 has a main body 130 and a plurality of structural members 140 vertically connected to the main body 130 , and a closed through hole 142 is defined at an end of each structural member 140 . The outer casing 200 is provided with a plurality of grooves 210 opposite to each structural member 140, each structural member 140 passes through each groove 210 and is processed to form two clamping portions 160, and each clamping portion 160 is respectively clamped to each groove 210 The outer two sides are tightly clamped to the outer casing 200 . The fastening mechanism referred to in this embodiment preferably means that each connecting structure 140 is processed to form two fastening portions 160 . The brake and clutch assembly 300 is installed between the cover plate 110 and the outer casing 200 .

In this embodiment, the cover plate 110 is preferably fixed and disposed on the inner side close to the seat cushion, and the outer casing 200 is relatively disposed on the outer side away from the seat cushion. By adjusting the handle (not shown) adjacent to the outer casing 200, the brake and clutch assembly 300 is linked to drive the displacement of the lifting mechanism (not shown) in the seat cushion. The outer casing 200 has a dish-shaped outline, and the grooves 210 are distributed on the dish-shaped flange 220 .

The brake and clutch assembly 300 referred to here is essentially composed of a brake mechanism and a clutch mechanism, wherein the brake mechanism includes a brake shaft 310, a brake drum 320 sleeved on the brake shaft 310 and a brake drum 320 A plurality of roller assemblies 330. One end of the brake shaft 310 passes through a shaft hole 120 of the cover plate 110 , and the other end is linked with the clutch mechanism. However, the clutch mechanism is not shown in this embodiment, and the actuation relationship between the brake mechanism and the clutch mechanism is in the prior art, and no further description is given here.

In the embodiment shown in FIGS. 2 to 4 , it further includes a brake ring 170 clamped between the cover plate 110 and the outer casing 200 . The brake ring 170 is also provided with a plurality of missing grooves 172, a ring body 174 and a ring hole 176 provided in the ring body 174 relative to each joint structure 140, wherein the inner peripheral surface of the ring hole 176 is further provided for each roller. The component 330 forms a locking or unlocking effect, which is also one of the sources of the peeling load. Each notch 172 of the ring body 174 is arranged corresponding to each groove 210 . Therefore, each connecting member 140 passes through each slot 172 and each groove 210 respectively, and fastens the cover plate 110 , the brake ring 170 and the outer casing 200 through riveting, stamping or other suitable processing methods.

Since each connecting structure 140 also has a long and narrow connecting body 150 and a connecting rod 152 connecting two side ends of the connecting body 150 , the closed perforation 142 is formed between the connecting rod 152 and the connecting body 150 .

However, in this embodiment, since each structural member 140 has two fastening portions 160 connected to each other, each structural member 140 is formed into a solid structure by means of riveting, thereby enhancing the strength of the member 140 .

Further, each tie structure 140 in this embodiment not only has the strength of the root of the tie body 150 , but also has the strength of the end of the tie body 150 . In other words, when the two fastening portions 160 formed by the plastic deformation of the connecting rod 152 bear the peeling load/shearing load on both sides, the closed perforation 142 between the connecting body 150 and the connecting rod 152 is deformed due to the riveting process. , strengthening the overall strength of each association member 140. In essence, the two fastening portions 160 are formed by connecting the connecting rods 152 , so that the ability of the two fastening portions 160 to withstand inward compression and deformation is greatly improved, and the peeling strength that can withstand becomes stronger.

Therefore, each connection structure 140 of the present invention makes the connection strength between the cover plate 110 , the brake ring 170 and the outer casing 200 better, and the durability and reliability are relatively improved. Furthermore, since the present invention can strengthen the binding effect with simple processing means, relatively thin materials or even low-strength materials can be used, thereby providing lightweight and inexpensive products.
