[0024] Many traditional seats, especially those in early or some economy vehicles, may only have fore-and-aft sliding function, or separate height adjustment, or separate tilt adjustment.
[0025] Since the height and tilt of the seat cannot be quickly adjusted, a seat adjustment device is needed to efficiently adjust the height and tilt of the seat cushion.
[0026] This invention proposes a seat adjustment device.
[0027] Please see Figure 1 , Figure 2 In one embodiment of the present invention, the seat adjustment device 100 includes: two sliding components 1, a front support component 2, at least one front drive component 3, a rear support component 4, and a seat cushion frame 5; the two sliding components 1 are spaced apart in the left-right direction and extend in the front-rear direction; the front support component 2 includes a front crossbeam 21 extending in the left-right direction and two front linkage mechanisms 22 connecting the two ends of the front crossbeam 21 to the two sliding components 1, each front linkage mechanism 22 including a first front linkage 221 and a second front linkage 222, one end of the first front linkage 221 being hinged to the front crossbeam 21, one end of the second front linkage 222 being hinged to the sliding component 1, and the other end being connected to the first front linkage 221. The other end is hinged; at least one front drive assembly 3 is disposed on the front support assembly 2 and is drivenly connected to the first front link 221 to drive the first front link 221 to swing; the rear support assembly 4 is disposed on the rear side of the front support assembly 2, the rear support assembly 4 includes a rear crossbeam 41 extending in the left-right direction, and two rear links 42 connecting the two ends of the rear crossbeam 41 to the two sliding assemblies 1, one end of each rear link 42 is hinged to the rear crossbeam 41, and the other end is hinged to the sliding assembly 1; and the seat frame 5 is disposed on the front support assembly 2 and the rear support assembly 4, the seat frame 5 includes a side connecting plate 51 extending in the front-rear direction, the side connecting plate 51 is hinged to one end of the front crossbeam 21 and the rear crossbeam 41.
[0028] In the technical solution of this invention, the seat frame 5 is used for seat cushion installation and adjustment of the seat cushion's height and angle, i.e., adjusting the height and angle of the seat frame 5. This is because the side connecting plate 51 of the seat frame 5 is hinged to one end of the front crossbeam 21 and the rear crossbeam 41, thus adjusting the height and relative height of the front crossbeam 21 and the rear crossbeam 41. The front drive assembly 3 drives the connecting rod in the front support assembly 2 to swing, changing the included angle between the first front connecting rod 221 and the second front connecting rod 222, thereby changing the height of the front crossbeam 21. Since the side connecting plate 51 is hinged to both the front crossbeam 21 and the rear crossbeam 41, the side connecting plate 51 acts as a "connecting rod": establishing a connection, transmitting power, and achieving a linkage effect. Because one end of the rear connecting rod 42 in the rear support assembly 4 is hinged to the rear crossbeam 41, and the other end is hinged to the sliding assembly 1, a quadrilateral structure is formed between the rear connecting rod 42, the side connecting plate 51, the sliding assembly 1, the first front connecting rod 221, and the second front connecting rod 222. In a quadrilateral structure, if the length of one "side" (the first front link 221 and the second front link 222 as a whole) or its angle with other "sides" changes, the positions of the other "sides" or "vertices" will also change accordingly. Therefore, the height of the rear crossbeam 41 will also change accordingly. Generally, the rear crossbeam 41 and the front crossbeam 21 move in opposite directions vertically. Therefore, the height of the front crossbeam 21 and the rear crossbeam 41, as well as their relative height, can be adjusted simultaneously. This achieves simultaneous adjustment of the height and angle of the seat frame 5, thus improving adjustment efficiency.
[0029] To adjust the angle between the first front link 221 and the second front link 222, and the distance between the connection end of the first front link 221 and the sliding assembly 1 and the connection end of the second front link 222 and the side connecting plate 51. In one embodiment, please refer to... Figures 3 to 5 The front drive assembly 3 is specifically configured as follows: the front drive assembly 3 includes a front drive motor 31, a first drive gear 32, and a first toothed plate 33; the front drive motor 31 is fixedly mounted on the first front connecting rod 221; the first drive gear 32 is connected to the front drive motor 31 in a transmission manner; and the first toothed plate 33 meshes with the first drive gear 32, and the first toothed plate 33 is fixed to the front crossbeam 21. The teeth of the first toothed plate 33 are arranged along an arc (not a circular arc), so when the first toothed plate 33 meshes with the first drive gear 32, the position of the front crossbeam 21 changes, which correspondingly drives the first front connecting rod 221 and the second front connecting rod 222 to move, thereby changing the included angle between the first front connecting rod 221 and the second front connecting rod 222, as well as the distance between the connection end of the first front connecting rod 221 and the sliding assembly 1 and the connection end of the second front connecting rod 222 and the side connecting plate 51.
[0030] To ensure that the first toothed plate 33 is always engaged with the first drive gear 32, the first drive gear 32 needs to be limited. Please refer to [link / reference needed]. Figures 3 to 5 Specifically: the first toothed plate 33 is provided with a limiting groove 331, and the front support assembly 2 also includes a limiting pin 34. One end of the limiting pin 34 is fixedly installed on the first front connecting rod 221, and the other end extends into the limiting groove 331 so as to slide relative to the first toothed plate 33 along the extending direction of the limiting groove 331. This ensures that the first toothed plate 33 is always engaged with the first drive gear 32 on the active path defined by the limiting pin 34.
[0031] To protect the first toothed plate 33 and the first drive gear 32, the front drive assembly 3 also includes a rack 35. (See attached image) Figures 3 to 5 The rack 35 is fixedly installed on the first toothed plate 33 and meshes with the first drive gear 32. That is, setting the rack 35 is equivalent to increasing the thickness of the teeth of the first toothed plate 33, which can distribute the pressure, avoid stress concentration, and improve the load-bearing capacity of the structure.
[0032] To ensure smoother transmission on both sides of the seat and to prevent asynchronous movement of the front linkage mechanisms 22 on both sides, which could cause the seat cushion frame 5 to tilt, two front drive components 3 are provided, each corresponding to a front linkage mechanism 22.
[0033] To ensure equal driving effect on both sides, the seat adjustment device 100 also includes a synchronization controller, which is electrically connected to the two front drive components 3 to control the synchronous movement of the two front drive components 3. That is, the synchronization controller ensures that the two front drive motors 31 rotate in the same direction.
[0034] Please see Figure 2 and Figure 6 To further adjust the height of the rear crossbeam 41, the seat adjustment device 100 also includes a rear drive assembly 6, which includes a rear drive motor 61, a second drive gear 62, and a second gear plate 63. The rear drive motor 61 is fixedly mounted on the side connecting plate 51; the second drive gear 62 is drively connected to the rear drive motor 61; and the second gear plate 63 is fixedly mounted on the rear link 42 and meshes with the second drive gear 62. By changing the angle between the rear link 42 and the side connecting plate 51, the angle between the rear link 42 and the sliding assembly 1 is adjusted, thereby changing the height of the rear crossbeam 41.
[0035] When the height of the rear crossbeam 41 is adjusted via the rear drive assembly 6, the height of the front crossbeam 21 will also change accordingly, but the adjustment range is smaller than that of the rear crossbeam 41. Similarly, when the height of the front crossbeam 21 is adjusted via the front drive assembly 3, the height of the rear crossbeam 41 will also change accordingly, but the adjustment range is smaller than that of the front crossbeam 21.
[0036] As mentioned earlier, the rear link 42, side connecting plate 51, sliding assembly 1, first front link 221, and second front link 222 form a quadrilateral structure. How to maintain the stability of this quadrilateral structure? This can be achieved through the self-locking of the motor, preserving the adjusted result. For example, the drive end of the front drive motor 31 is equipped with a mechanical self-locking mechanism. This self-locking can be achieved regardless of whether the front drive motor 31 is energized. Therefore, the angle between the first front link 221 and the second front link 222, and the distance between the connection end of the first front link 221 and the sliding assembly 1 and the connection end of the second front link 222 and the side connecting plate 51, remain unchanged after adjustment. To ensure that the front drive motor 31 can smoothly complete the linkage adjustment of the front and rear crossbeams 41, the rear drive motor 61 is de-energized during operation. The drive end of the rear drive motor 61 is set to self-lock when energized and not self-locking when de-energized. Therefore, during the adjustment of the front drive motor 31, the second drive gear 62 and the second toothed plate 63 can rotate relative to each other, thereby adjusting the position of the rear crossbeam 41. After the front drive motor 31 is adjusted and then de-energized (at this time, the lengths of the four "sides" of the quadrilateral structure are determined), the rear drive motor 61 is energized. The rear drive motor 61 has a self-locking function, and the drive shaft of the rear drive motor 61 does not rotate. Therefore, the second drive gear 62 and the second toothed plate 63 cannot rotate relative to each other, that is, the angle between the rear connecting rod 42 and the side connecting plate 51 is fixed, so the quadrilateral structure is stable. When the drive shaft of the rear drive motor 61 rotates, the second drive gear 62 and the second toothed plate 63 can rotate relative to each other, further changing the position of the rear crossbeam 41.
[0037] The present invention also proposes a seat, which includes a seat cushion and a seat adjustment device 100.
