[0034] Two clamping blocks 34, the two clamping blocks 34 are arranged opposite to each other, the locking block 32 is located between the two clamping blocks 34, and a second groove 341 and an arc-shaped slot 342 are provided on one side of the clamping block 34 close to the locking block 32, the first groove 321 and the second groove 341 are correspondingly matched to form a clamping hole for clamping the seat bow 11, and the arc-shaped slot 342 is used to accommodate the arc-shaped convex edge 311;

[0035] The fastening assembly 33 connects the two clamping blocks 34 .

[0036] From the above description, it can be seen that the beneficial effects of the utility model are: the locking assembly 3 has a novel structure, fewer components, a simple structure, and is easy to assemble and manufacture. It can be adapted to the universal seat cushion 1 with a seat bow 11 on the market. The three-piece clamping and fixing structure is convenient for disassembly, assembly and replacement of the vehicle seat, and the installation is symmetrical. The overall structure of the locking assembly 3 is firm and not easy to deform. More importantly, the pitch angle can be adjusted, which greatly improves the user experience.

[0037] Furthermore, an arc-shaped groove 312 is provided at the top of the fixing seat 31 , a partial area of ​​the clamping block 34 is accommodated in the arc-shaped groove 312 , and the arc-shaped protrusion 311 is provided along the edge of the arc-shaped groove 312 .

[0038] From the above description, it can be seen that the arc groove 312 can at least avoid the clamping block 34, making the overall structure of the locking assembly 3 more compact, which is beneficial to reducing the production consumables of the fixing seat 31 and the clamping block 34, thereby reducing the manufacturing cost of the locking assembly 3.

[0039] Furthermore, a downward convex structure 322 is provided at the bottom of the locking block 32 , and the downward convex structure 322 extends into the gap between the two clamping blocks 34 .

[0040] It can be seen from the above description that the existence of the downward convex structure 322 enables the two clamping blocks 34 to better play the role of positioning the locking block 32 .

[0041] Furthermore, the clamping block 34 has a friction surface 343 for resisting the fixing seat 31 .

[0042] From the above description, it can be seen that the friction force against the fixing seat 31 can form a larger static friction force between the clamping block 34 and the fixing seat 31, thereby preventing the clamping block 34 from unexpectedly rotating relative to the fixing seat 31 and causing the seat cushion 1 connected to the locking assembly 3 to accidentally pitch.

[0043] Furthermore, the friction surface 343 is located in the slot, and the friction surface 343 contacts the arc-shaped convex edge 311 .

[0044] It can be seen from the above description that arranging the friction surface 343 in the slot can make the locking assembly 3 more compact and reduce the production consumables of the clamping block 34 .

[0045] Furthermore, the first groove 321 on the clamping block 34 is a U-shaped groove.

[0046] It can be seen from the above description that the U-shaped groove can guide a partial area of ​​the locking block 32 to extend into the first groove 321 , and at the same time allow the locking hole to better lock the seat bow 11 .

[0047] The vehicle seat mechanism comprises the locking assembly 3 mentioned above.

[0048] It can be seen from the above description that the seat cushion 1 in the vehicle seat mechanism can at least be adjusted in pitch.

[0049] Furthermore, it also includes a seat cushion 1, a seat bow 11, a seat rod 2, a slider 4, a slide rail 5 and a locking mechanism 6, the seat cushion 1 is fixedly connected to the seat bow 11, the locking assembly 3 is locked and connected to the seat bow 11, the fixed seat 31 is connected to the slider 4, the slider 4 is slidably connected to the slide rail 5, the slide rail 5 is fixedly connected to the seat rod 2, and the locking mechanism 6 is used to lock the slider 4 and the slide rail 5.

[0050] It can be seen from the above description that the seat cushion 1 in the seat mechanism can be adjusted to slide forward and backward.

[0051] Furthermore, the locking mechanism 6 includes a matching T-nut 61 and a locking screw 62, a through hole 51 is provided on the slide rail 5, the slider 4 has a straight groove 41 arranged along its sliding direction, one end of the locking screw 62 passes through the through hole 51 and the straight groove 41 to connect the T-nut 61, and the T-nut 61 presses the slider 4.

[0052] It can be seen from the above description that the locking mechanism 6 has a simple structure and good working stability.

[0053] A fitness bicycle comprises the above-mentioned seat mechanism.

[0054] It can be seen from the above description that the fitness bike at least has the beneficial effects of the above-mentioned seat mechanism.
