Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat angle adjustment, in particular to a novel automobile seat angle adjuster. Background Art

[0002] The car seat recliner is a component used to adjust the angle of the seat back, thereby providing a more comfortable riding environment for the driver or passenger. Some new car seat recliners include a recliner body, the interior of the recliner body is connected to the rotating shaft of the car seat back through a torsion spring, and the front end of the rotating shaft is connected to the handle in the adjuster body through a locking assembly. When the seat back is adjusted in angle, the rotating shaft is driven to rotate by the seat back, and the torsion spring torsion increases, thereby adjusting the angle of the seat back. The rotation of the rotating shaft is restricted by the locking assembly. When the seat back is reset, the seat back is reversed and reset around the axis of the rotating shaft through the torsion spring's own torque. However, as the seat back adjustment angle increases, the torsion spring torsion increases, and when the seat back is reset and rebounds after falling down, the torsion spring torsion causes the seat back to rebound too quickly and the pressure to be too high, making the human body feel uncomfortable. This needs to be improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new type of automobile seat angle adjuster. The device applies external friction force to the seat backrest through an elastic element to reset the seat back, thereby reducing the reset rebound speed of the seat backrest driven by the torsion spring, and the applied external friction force gradually decreases as the torsion force of the torsion spring decays. The seat backrest rebounds steadily and is easy to use, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel car seat recliner, comprising an adjustment shell and a rebound deceleration mechanism;

[0006] Rebound deceleration mechanism: It is arranged between the adjustment shell and the annular block. The device applies external friction force to the seat backrest through elastic elements to reduce the reset rebound speed of the seat backrest driven by the torsion spring. The applied external friction force gradually decreases as the torsion force of the torsion spring decays. The seat backrest rebound speed is stable and easy to use.

[0007] Furthermore, the rebound deceleration mechanism includes a telescopic column, a spring, a deceleration seat and an annular seat. The annular seat is arranged on the rear side of the annular block. The side wall of the adjustment shell is provided with a deceleration seat through evenly distributed telescopic columns and springs. The springs are movably connected to the outer ends of adjacent telescopic columns. The deceleration seat is installed in cooperation with the annular seat to reduce the reset rebound speed of the seat back driven by the torsion spring.

[0008] Furthermore, the rebound deceleration mechanism also includes a rubber pad, which is arranged on the inner arc surface of the deceleration seat to improve the friction deceleration effect between the deceleration seat and the annular seat.

[0009] Furthermore, a cylindrical shell is provided at the left end of the locking block, an adjusting handle is slidably connected inside the cylindrical shell, a tension spring is provided between the adjusting shell and the cylindrical shell, and the adjusting handle of the device can be used to adjust the shaft length according to the vehicle model and usage requirements.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the new car seat recliner has the following advantages:

[0014] When the new type of car seat back is reset, the downward adjustment handle drives the locking block to move, releasing the rotation limit of the angle shaft, and then the rotating arm drives the seat back to reverse and reset along the axis of the angle shaft through the torsion spring's own torque. In this process, the compression elastic force of the spring causes the reduction seat to elastically squeeze the annular seat, thereby indirectly reducing the reset speed of the seat back through the rotating arm. The rubber pad increases the contact friction to increase the reset deceleration effect of the reduction seat on the angle shaft. As the rotating arm drives the seat back to reset, the torsion spring's own torque gradually decreases, and the seat back reset speed continues to slow down. The annular seat adopts an irregular circular design. At this time, as the torsion spring's own torque gradually decreases, the deceleration seat The straight-line distance between the seat and the axis of the corner shaft gradually becomes smaller than the initial straight-line distance between the two, and the telescopic end of the telescopic column and the spring gradually stretch, so that the deceleration friction force applied by the deceleration seat to the corner shaft gradually decreases, avoiding the deceleration friction force being greater than the torque of a certain attenuation state of the torsion spring, which causes the seat back to be stuck in a certain position and cannot be accurately reset. The torsion spring torsion and the deceleration friction force gradually decrease synchronously, so that the seat back reset rebound speed is stable. The new car seat angle adjuster applies external friction force to the seat back reset through an elastic element, reduces the reset rebound speed of the seat back driven by the torsion spring, and the applied external friction force gradually decreases with the attenuation of the torsion spring torsion, so the seat back rebound speed is stable and easy to use.

When using the new car seat recliner , the adjusting handle 11 is toggled to slide along the cylinder shell 10, and then the locking bolt 13 is rotated to move it backward through the threaded connection, so as to be plugged into the adjacent locking hole 12, and then the adjusting handle 11 of the device is adjusted and fixed according to the vehicle model and usage requirements, and the relative sliding between the operator's hand and the adjusting handle 11 is prevented by the anti-slip pattern. When adjusting the angle of the new automobile seat, the adjusting handle 11 is pressed down to make the locking block 8 rotate around the axis of the rotating shaft 7 so as to be separated from the annular block 3, and the rotation limit of the angle shaft 2 is released, and the tension spring 9 is stretched, and then the rotating arm 6 drives the angle shaft 2 to rotate through the seat back, so as to adjust the angle of the new automobile seat back, and the angle shaft 2 drives the annular block 3 to rotate so as to increase the torsion of the torsion spring 4, and then the downward pressure applied to the adjusting handle 11 is released, and the locking block 8 is engaged with the annular block 3 through the tensile elastic force of the tension spring 9, so as to limit the rotation of the angle shaft 2, and then the angle adjustment operation of the new automobile seat is realized;

[0023] Rebound deceleration mechanism 5: It is arranged between the adjustment shell 1 and the annular block 3. The rebound deceleration mechanism 5 includes a telescopic column 51, a spring 52, a deceleration seat 53 and an annular seat 55. The annular seat 55 is arranged on the rear side of the annular block 3. The side wall of the adjustment shell 1 is provided with a deceleration seat 53 through evenly distributed telescopic columns 51 and springs 52. The springs 52 are movably connected to the outer ends of the adjacent telescopic columns 51. The deceleration seat 53 is installed in cooperation with the annular seat 55. The rebound deceleration mechanism 5 also includes a rubber pad 54, which is arranged on the inner arc surface of the deceleration seat 53. When the new When the car seat back is reset, the adjustment handle 11 is pressed down to drive the locking block 8 to move, thereby releasing the rotation limit of the corner shaft 2. Then, the rotating arm 6 drives the seat back to reverse and reset along the axis of the corner shaft 2 through the torsion force of the torsion spring 4. In this process, the compression elastic force of the spring 52 causes the reduction seat 53 to elastically squeeze the annular seat 56, thereby indirectly reducing the reset speed of the seat back through the rotating arm 6. The rubber pad 54 increases the contact friction to improve the reset deceleration effect of the reduction seat 53 on the corner shaft 2. The rotating arm 6 drives the seat back to return to its original position, the torque of the torsion spring 4 itself gradually decreases, and the speed of returning the seat back to its original position becomes slower and slower. The annular seat 55 adopts an irregular circular design. At this time, as the torque of the torsion spring 4 itself gradually decreases, the straight-line distance between the reduction seat 53 and the axis of the corner shaft 2 gradually becomes smaller than the straight-line distance between the two at the beginning, and the telescopic end of the telescopic column 51 and the spring 52 gradually stretch, so that the deceleration friction force applied by the deceleration seat 53 to the corner shaft 2 gradually decreases, thereby avoiding the seat back from getting stuck due to the deceleration friction force being greater than the torque of a certain attenuation state of the torsion spring 4. If the seat back cannot be accurately reset at a certain position, the torsion force of the torsion spring 4 and the deceleration friction force are gradually reduced synchronously, so that the seat back reset rebound speed is stable, and the rotation of the synchronization rod 14 is limited by the reset limit rod 15 to avoid the new car seat back reset beyond the corresponding stroke. The new car seat angle adjuster applies external friction force to the seat back reset through elastic elements, reduces the reset rebound speed of the seat back driven by the torsion spring 4, and the applied external friction force gradually decreases with the attenuation of the torsion force of the torsion spring 4, and the seat back rebound speed is stable, which is easy to use.

[0024] The working principle of a novel car seat angle adjuster provided by the utility model is as follows: when using the novel car seat angle adjuster, the adjusting handle 11 is toggled to make it slide along the cylinder shell 10, and then the locking bolt 13 is rotated to make it move backward through the threaded connection, so as to be plugged into the adjacent locking hole 12, and then the adjusting handle 11 of the device is adjusted and fixed in length according to the vehicle model and usage requirements, and the relative sliding phenomenon between the operator's hand and the adjusting handle 11 is prevented by the anti-slip pattern. When adjusting the angle of the novel car seat, the adjusting handle 11 is pressed down to make the locking block 8 rotate around the axis of the rotating shaft 7 so as to be engaged with the annular block 3. Separate, release the rotation limit of the corner shaft 2, stretch the tension spring 9, and then make the rotating arm 6 drive the corner shaft 2 to rotate through the seat back, so as to adjust the angle of the new car seat back, the corner shaft 2 drives the annular block 3 to rotate, so that the torsion of the torsion spring 4 increases, and then release the downward pressure applied to the adjustment handle 11, and the locking block 8 is engaged with the annular block 3 through the stretching elastic force of the tension spring 9, so as to limit the rotation of the corner shaft 2, and then realize the angle adjustment operation of the new car seat, when the new car seat back is reset, the adjustment handle 11 is pressed down to drive the locking block 8 to move, and the rotation of the corner shaft 2 is released. The rotation limit is achieved, and then the torsion force of the torsion spring 4 is used to make the rotating arm 6 drive the seat back to reverse and reset along the axis of the angular axis 2. In this process, the compression force of the spring 52 causes the reduction seat 53 to elastically squeeze the annular seat 56, thereby indirectly reducing the reset speed of the seat back through the rotating arm 6. The rubber pad 54 increases the contact friction force to improve the reset deceleration effect of the reduction seat 53 on the angular axis 2. As the rotating arm 6 drives the seat back to reset, the torsion force of the torsion spring 4 is gradually reduced, and the reset speed of the seat back is continuously slowed down. The annular seat 55 is designed with an irregular circle. At this time, as the torsion spring 4 is gradually reduced, the torsion force of the torsion spring 4 is gradually reduced. The linear distance between the deceleration seat 53 and the axis of the corner shaft 2 gradually decreases, and the linear distance between the deceleration seat 53 and the axis of the corner shaft 2 gradually becomes smaller than the initial linear distance between the two. The telescopic end of the telescopic column 51 and the spring 52 are gradually stretched, so that the deceleration friction force applied by the deceleration seat 53 to the corner shaft 2 is gradually reduced, thereby preventing the deceleration friction force from being greater than the torque of a certain attenuation state of the torsion spring 4, which causes the seat back to be stuck in a certain position and cannot be accurately reset. The torsion of the torsion spring 4 and the deceleration friction force are gradually reduced synchronously, so that the seat back reset rebound speed is stable, and the rotation of the synchronization rod 14 is restricted by the reset limit rod 15 to prevent the new car seat back from resetting beyond the corresponding stroke.
