The structure of the second support mechanism 5 is the same as that of the first support mechanism 3. A through groove 405 is provided on the side of the column 402 corresponding to the position of the second support mechanism 5. When the height of the backrest mechanism 4 needs to be adjusted during use of the seat, the threaded rod 404 is driven to rotate through the adjustment mechanism 2, and the telescopic column 403 is driven to slide along the inner wall of the side of the column 402 through the thread, thereby driving the upper mounting plate 302 to move up and down. The top end of the first support rod 304 is rotated along the pin on the side of the upper mounting plate 302, and the pin on the top end of the original connecting block 303 at the bottom end of the first support rod 304 is flipped, so that the two ends of the second support rod 307 are rotated along the connecting block 303 and the pins on the top end of the lower mounting plate 301 respectively, so that the connecting block 303, the first support rod 304 and the second support rod 307 cooperate to support the driver's back. At the same time, the first support rod 304 and the second support rod 307 have the same length, so that the connecting block 303 is located at the center of the upper mounting plate 302 and the lower mounting plate 301 and remains parallel.

[0024] Among them, a first installation groove 306 is opened on the side of the connecting block 303, and a connecting rod 305 is movably connected to the side of the first installation groove 306. When the connecting blocks 303 on both sides move, the connecting rod 305 slides along the first installation groove 306 and connects the two connecting blocks 303 through the connecting rod 305.

[0025] The adjusting mechanism 2 includes a transmission shaft 211, the side of the transmission shaft 211 is movably connected to the inner wall of the side of the bottom plate 401, the bottom end of the threaded rod 404 passes through the inner wall of the top end of the bottom plate 401 and is fixedly connected to the driven bevel gear 406, the side of the transmission shaft 211 is fixedly connected to the active bevel gear 202, the side of the active bevel gear 202 and the side of the driven bevel gear 406 are meshed with each other, the side of the transmission shaft 211 is fixedly connected to the worm gear 204, and the side of the bottom plate 401 A worm 203 is movably sleeved, and the bottom end of the worm 203 meshes with the top end of the worm gear 204.

At the same time, the worm 203 can drive the worm gear 204 to rotate, and the worm gear 204 cannot drive the worm 203 to rotate, so the transmission shaft 211 is fixed.

[0026] The side of the bottom plate 401 is provided with a second mounting groove 407 corresponding to the position of the worm 203, the side of the second mounting groove 407 is movably connected to the limit block 205, the side of the limit block 205 is fixedly connected to the knob 201, the side inner wall of the knob 201 is fixedly connected to the second clamping block 210, the side of the second clamping block 210 is fixedly connected to the first clamping block 207, the side of the bottom plate 401 is provided with a second clamping groove 408, the side of the second clamping groove 408 is meshed with the side of the second clamping block 210, and the side of the worm 203 is provided with a second clamping groove 408. A first card slot 206 is provided, and the side surface of the first card slot 206 meshes with the side surface of the first card block 207. When the worm 203 needs to be rotated, the knob 201 is pulled outward to make the second card block 210 move with the knob 201 and separate from the second card slot 408. The first card block 207 is rotated to rotate, and the worm 203 is rotated by the mutual meshing of the first card block 207 and the first card slot 206.

After the adjustment is completed, the tension spring 209 pulls the knob 201 to insert the second clamping block 210 into the second clamping slot 408. At the same time, when the knob 201 is rotated, the mounting ring 208 rotates to avoid affecting the tension spring 209.

[0028] The length of the first card slot 206 is twice that of the second card slot 408 , and the length of the first card block 207 is the same as that of the first card slot 206 , ensuring that when the second card block 210 is separated from the second card slot 408 , the first card block 207 and the first card slot 206 are always engaged with each other.

[0029] The working principle of the utility model is as follows: when the height of the backrest mechanism 4 needs to be adjusted, the knob 201 is pulled outward to make the second block 210 move with the knob 201 and separate from the second slot 408, and the knob 201 is turned to drive the first block 207 to rotate, and the worm 203 is driven to rotate through the mutual meshing of the first block 207 and the first slot 206, and the transmission shaft 211 is driven to rotate through the mutual meshing of the worm gear 204 and the worm 203, and the threaded rod 404 is driven to rotate through the mutual meshing of the active bevel gear 202 and the driven bevel gear 406, and the telescopic column 403 is driven to slide along the inner wall of the side of the column 402 through the thread. The upper mounting plate 302 moves up and down, so that the top end of the first support rod 304 rotates along the pin on the side of the upper mounting plate 302, and the pin on the top end of the original connecting block 303 at the bottom end of the first support rod 304 flips over, so that the two ends of the second support rod 307 rotate along the connecting block 303 and the pin on the top end of the lower mounting plate 301 respectively, so that the connecting block 303, the first support rod 304 and the second support rod 307 cooperate to support the driver's back. After the adjustment is completed, the knob 201 is released, and the tension spring 209 pulls the knob 201 to insert the second clamping block 210 into the second clamping slot 408 to prevent the knob 201 from rotating.
