The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0019] See also Figure 1-Figure 4 The utility model provides a single-seat folding chair, comprising a seat body 1, a backrest 2 and an adjustment mechanism, wherein the adjustment mechanism comprises an armrest 3, a first transmission plate 4, a rotation center 5, a first clamping block 6 and a first mounting plate 7;

[0020] The armrest 3 is rotatably connected to the seat body 1 and is located on one side of the seat body 1. The first transmission plate 4 is fixedly connected to the armrest 3 and is located on one side of the armrest 3. The rotation center 5 is fixedly connected to the seat body 1 and rotatably connected to the first transmission plate 4. The first clamping block 6 is fixedly connected to the first transmission plate 4 and is located on one side of the first transmission plate 4. The first mounting plate 7 is rotatably connected to the seat body 1 and fixedly connected to the backrest 2.

[0021] In this embodiment, the seat body 1 provides installation adjustment for the adjustment mechanism. When the seat needs to be adjusted, the armrest 3 is pulled upward, and the armrest 3 drives the first transmission plate 4 to rotate on the rotation center 5. The first transmission plate 4 drives the first block 6 to move, releasing the limit on the first mounting plate 7, pushing the backrest 2, and driving the backrest 2 to rotate toward the side close to the seat body 1 through the first mounting plate 7 until the backrest 2 rotates to the preset angle to complete the adjustment of the seat, thereby solving the problem that the existing car seat needs to be unlocked in multiple places to achieve the seat folding.

[0022] Furthermore, the adjustment mechanism further includes a first tension spring 8 , which is fixedly connected to the first transmission plate 4 and to the seat body 1 .

[0023] In this embodiment, the first transmission plate 4 can be reset by the rebound force of the first tension spring 8 .

[0024] Furthermore, the adjustment mechanism also includes a side unlocking component, which includes a first cable 9, a second transmission plate 10, a second block 11, a second mounting plate 12 and a second tension spring 13. The first cable 9 is fixedly connected to the second transmission plate 10 and is located on one side of the second transmission plate 10. The second transmission plate 10 is rotatably connected to the seat body 1 and is fixedly connected to the output end of the second cable 16. The second block 11 is fixedly connected to the second transmission plate 10 and is located on one side of the second transmission plate 10. The second mounting plate 12 is rotatably connected to the seat body 1 and is fixedly connected to the backrest 2. The second tension spring 13 is fixedly connected to the second transmission plate 10 and is fixedly connected to the seat body 1.

[0025] In this embodiment, when the first transmission plate 4 moves, it drives the first cable 9 to contract, the first cable 9 drives the second transmission plate 10 to rotate, and the second transmission plate 10 drives the second block 11 to move, releasing the limit on the second mounting plate 12. At this time, the backrest 2 can be driven to fold by the second mounting plate 12.

[0026] Furthermore, the adjustment mechanism also includes a rear unlocking component, which includes a snap clip 14, a buckle 15 and a second cable 16. The snap clip 14 is fixedly connected to the seat body 1 and is located on one side of the seat body 1. The buckle 15 rotates with the snap clip 14 and is located on the snap clip 14. The second cable 16 is fixedly connected to the first transmission plate 4 and is fixedly connected to the buckle 15.

[0027] In this embodiment, when the first transmission plate 4 moves, it drives the second cable 16 to contract, and the second cable 16 drives the buckle 15 to rotate, releasing the limit of the seat body 1 by the snap clip 14 and the buckle 15, so that the seat body 1 can be lifted to the side away from the vehicle body, thereby achieving further folding of the seat body 1.

[0028] Furthermore, the adjustment mechanism also includes a front unlocking component, which includes a connecting frame 17, a support seat 18, a connecting rope 19 and a pin 20. The connecting frame 17 is fixedly connected to the seat body 1 and is located on one side of the seat body 1. The support seat 18 is rotatably connected to the connecting frame 17 and is located on one side of the connecting frame 17.

The pin 20 is fixedly connected to the connecting rope 19 and is inserted into the connecting frame 17 and the support seat 18.

[0029] In this embodiment, the connecting frame 17 provides installation conditions for the support seat 18 and the pin 20. The support seat 18 and the connecting frame 17 can be limited by the pin 20. By pulling out the pin 20, the seat body 1 can be rotated. The seat body 1 is driven to rotate on the support seat 18 by the connecting frame 17, thereby achieving further folding of the seat body 1. The connecting rope 19 can prevent the pin 20 from being lost.

[0030] Seat folding process:

[0031] Pull the armrest 3 upward, the armrest 3 drives the first transmission plate 4 to rotate on the rotation center 5, the first transmission plate 4 drives the first clamping block 6 to move, and releases the limit on the first mounting plate 7. At the same time, the first transmission plate 4 drives the first cable 9 and the second cable 16 to retract, the first cable 9 drives the second transmission plate 10 to rotate, and the second transmission plate 10 drives the second clamping block 11 to move, and releases the limit on the second mounting plate 12, pushing the backrest 2. The backrest 2 is driven by the first mounting plate 7 and the second mounting plate 12 to rotate toward the side close to the seat body 1 until the backrest 2 rotates to a preset angle. The second cable 16 drives the buckle 15 to rotate, and releases the limit of the clamping clip 14 and the buckle 15 on the seat body 1. The pin 20 is pulled out, and the seat body 1 can be lifted to the side away from the vehicle body. After the seat body 1 is adjusted to the preset angle, the pin 20 is inserted into the support seat 18 and the connecting frame 17 to complete the folding of the seat.
