Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat angle adjustment, in particular to an automobile seat angle adjuster assembly. Background Technique

[0002] An angle adjuster is a device installed on an automobile seat to realize the adjustment of the seat back angle. Some automobile seat angle adjusters include a regulator arranged in a housing. The ratchet wheel of the angle adjuster is fixedly connected to the seat frame. An operating handle is fixedly connected to the central shaft of the regulator. A bracket is fixedly connected to the housing. The bracket and the operating handle are connected by a spring. A limiting block is fixedly arranged on the seat frame. A volute spring is arranged outside the limiting block. Two ends of the volute spring are respectively clamped on the limiting block and the seat frame. Through the above method, the automobile seat angle adjuster of the utility model can improve the reset speed during the reset process of the seat back and ensure accurate reset. However, during the reset process of the seat back, due to the too large initial internal reset torque of the volute spring, it is easy to make the reset moving speed of the seat back too fast during the reset process of the seat back, and it is easy to collide with the user, there are potential safety hazards. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automobile seat angle adjuster assembly. The device can buffer the reset of the angle adjuster by using transmission elements and elastic elements, and the buffering force decreases gradually with the reset moving distance of the seat frame, so that the reset process of the seat frame is uniform and stable, and it is safe to use, and the problems in the background technique can be effectively solved.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: an automobile seat angle adjuster assembly, including an adjustment housing;

[0005] Adjustment housing: A rotating shaft is rotatably connected to the inside thereof through a bearing. A reset housing is arranged at the rear end of the rotating shaft. The inside of the reset housing is fixedly connected to the rotating shaft through a volute spring. A seat frame is arranged in the middle of the rotating shaft. A sliding seat is slidably connected in a sliding groove opened on the rear wall of the adjustment housing. The upper side of the sliding seat is provided with a buffer seat through the telescopic ends of uniformly distributed telescopic columns. The buffer seat is cooperatively installed with the rotating shaft. The device can buffer the reset of the angle adjuster by using transmission elements and elastic elements, and the buffering force decreases gradually with the reset moving distance of the seat frame, so that the reset process of the seat frame is uniform and stable, and it is safe to use.

[0006] Furthermore, uniformly distributed springs are arranged between the sliding seat and the adjacent buffer seats. The springs are all movably sleeved on the outer ends of the adjacent telescopic columns. Through the elastic force of the spring compression, the buffer seat is attached to the rotating shaft, and then an elastic buffer force is applied to the reset of the rotating shaft of the automobile seat angle adjuster assembly.

[0007] Further, a rubber pad is provided on the inner arc surface of the buffer seat to improve the reset buffer effect of the buffer seat on the rotating shaft.

[0008] Further, a fixed seat is provided on the rear wall of the adjusting shell. A stud is rotatably connected to the upper side of the fixed seat through a bearing. The stud is threadedly connected to the sliding seat. Taper gears are provided at the upper end of the stud and the rear end of the rotating shaft, and the taper gears are meshed with each other. Through the transmission element, the buffer force of the buffer part in the vehicle seat angle adjuster assembly gradually increases as the vehicle seat is adjusted.

[0009] Further, an adjusting rod is rotatably connected to the inside of the adjusting shell through a driven shaft. Uniformly distributed teeth are provided at the right end of the adjusting rod, and a gear is provided at the front end of the rotating shaft. The teeth are fitted and installed with the gear to limit the angle adjustment of the vehicle seat angle adjuster assembly.

[0010] Further, a tension spring is provided between the adjusting rod and the adjusting shell. Through the tension spring, the adjusting rod in the vehicle seat angle adjuster assembly can automatically reset after moving.

[0011] Further, uniformly distributed anti-slip lines are provided at the left end of the adjusting rod to prevent relative sliding between the user's hand and the adjusting rod when adjusting the angle of the vehicle seat angle adjuster assembly.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The vehicle seat angle adjuster assembly has the following advantages:

[0013] When the vehicle seat is adjusted and then reset, the adjusting rod is pulled to release the locking of the angle adjuster by the same principle. Subsequently, the internal torsion of the volute spring is used to make the rotating shaft drive the seat frame to reverse and reset around its own axis. At this time, the compression elastic force of the spring makes the buffer seat elastically squeeze the outer side of the rotating shaft, and then the contact elastic extrusion force is used to slow down the reset speed of the seat frame. At the same time, as the seat frame gradually resets, the sliding seat gradually moves away from the rotating shaft through meshing connection and threaded connection, so that the reset extrusion buffer force applied by the buffer seat to the rotating shaft gradually decreases, so that the moving speed of the seat frame is uniform during the reset buffer process. The transmission element and the elastic element can buffer the reset of the angle adjuster, and the buffer strength decreases gradually as the reset moving distance of the seat frame increases, so that the reset process of the seat frame is uniform, stable and safe to use.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , this embodiment provides a technical solution: an automobile seat adjuster assembly, including an adjusting housing 1;

[0022] Adjusting housing 1: A rotating shaft 2 is rotatably connected inside it through a bearing. A reset housing 3 is provided at the rear end of the rotating shaft 2. The inside of the reset housing 3 is fixedly connected to the rotating shaft 2 through a volute spring 4. A seat frame 5 is provided in the middle of the rotating shaft 2. A sliding seat 6 is slidably connected in a chute opened on the rear wall of the adjusting housing 1. The upper side of the sliding seat 6 is provided with a buffer seat 9 through the telescopic ends of uniformly distributed telescopic columns 7. The buffer seat 9 is cooperatively installed with the rotating shaft 2. Uniformly distributed springs 8 are provided between the sliding seat 6 and the adjacent buffer seat 9. The springs 8 are all movably sleeved on the outer ends of the adjacent telescopic columns 7. A rubber pad 10 is provided on the inner arc surface of the buffer seat 9. A fixing seat 11 is provided on the rear wall of the adjusting housing 1. A stud 12 is rotatably connected to the upper side of the fixing seat 11 through a bearing. The stud 12 is threadedly connected to the sliding seat 6. Bevel gears 13 are provided at the upper end of the stud 12 and the rear end of the rotating shaft 2. The bevel gears 13 are meshed and connected. During the use of the vehicle seat adjuster, after the self-locking of the angle adjuster is released, press the seat so that the seat frame 5 drives the rotating shaft 2 to rotate forward around its own axis, thereby adjusting the angle of the vehicle seat. During this process, since the outer end of the volute spring 4 is fixed to the inner wall of the reset housing 3 and the inner end of the volute spring 4 is fixed to the outer side surface of the rotating shaft 2, as the seat frame 5 drives the rotating shaft 2 to rotate forward, the internal torque of the volute spring 4 gradually increases. At the same time, as the rotating shaft 2 rotates forward, the rotating shaft 2 makes the stud 12 rotate through the meshing connection between the bevel gears 13. The stud 12 makes the sliding seat 6 move along the chute through threaded connection, indirectly driving the buffer seat 9 to approach the rotating shaft 2 and squeeze it. The telescopic ends of the telescopic columns 7 and the springs 8 are gradually compressed. When the vehicle seat is reset after the angle adjustment, pull the adjusting rod 16 to release the rotational limit of the rotating shaft 2, and then the internal torque of the volute spring 4 makes the rotating shaft 2 drive the seat frame 5 to rotate reversely around its own axis for reset. During this process, the compression elastic force of the spring 8 makes the buffer seat 9 squeeze the outer side surface of the rotating shaft 2 that rotates synchronously with the seat frame 5. Through the contact extrusion force, the reset speed of the seat frame 5 is slowed down. At the same time, as the seat frame 5 gradually resets, the rotating shaft 2 makes the sliding seat 6 gradually move away from the rotating shaft 2 through the meshing connection between the bevel gears 13 and the threaded connection between the stud 12 and the sliding seat 6, thereby making the reset extrusion buffer force exerted by the buffer seat 9 on the rotating shaft 2 gradually decrease, so that the moving speed of the seat frame 5 is uniform during the reset buffer process. The rubber pad 10 improves the reset buffer effect of the buffer seat 9 on the rotating shaft 2 by increasing the contact friction. This device can buffer the reset of the angle adjuster by using transmission elements and elastic elements, and the buffer force decreases gradually with the reset moving distance of the seat frame 5, making the reset process of the seat frame 5 uniform, stable and safe to use;

[0023] Among them, a regulating rod 16 is rotatably connected inside a regulating housing 1 through a driven shaft 15. Uniformly distributed engaging teeth 17 are provided at the right end of the regulating rod 16, and a gear 14 is provided at the front end of a rotating shaft 2. The engaging teeth 17 are fitted and installed with the gear 14. A tension spring 18 is provided between the regulating rod 16 and the regulating housing 1. Anti-slip lines are uniformly distributed at the left end of the regulating rod 16. During the use of the vehicle seat adjuster, the regulating rod 16 is pulled upward to reverse it around the axis of the driven shaft 15, so that the engaging teeth 17 are separated from the gear 14, thereby releasing the rotational limit on the rotating shaft 2. The tension spring 18 is stretched. Through the anti-slip lines, relative sliding between the hand and the regulating rod 16 is avoided when the user operates the regulating rod 16. After the vehicle seat is adjusted in angle, the regulating rod 16 is released. Through the tensile elastic force of the tension spring 18, the regulating rod 16 is reversed and reset around the axis of the driven shaft 15, so that the engaging teeth 17 are engaged with the gear 14, thereby locking the vehicle seat after the angle adjustment.

[0024] The working principle of an automobile seat adjuster assembly provided by the utility model is as follows: During the use of an automobile seat adjuster, the adjusting lever 16 is pulled upward to reverse around the axis of the driven shaft 15, so that the engaging teeth 17 are away from the gear 14, thereby releasing the rotational limit of the rotating shaft 2. The tension spring 18 is stretched, and the anti-slip pattern is used to avoid the relative sliding phenomenon between the hand and the adjusting lever 16 when the user operates the adjusting lever 16. Subsequently, the seat is pressed so that the seat frame 5 drives the rotating shaft 2 to rotate forward around its own axis, thereby adjusting the angle of the automobile seat. During this process, since the outer end of the scroll spring 4 is fixed to the inner wall of the reset housing 3, and the inner end of the scroll spring 4 is fixed to the outer side surface of the rotating shaft 2, as the seat frame 5 drives the rotating shaft 2 to rotate forward, the internal torque of the scroll spring 4 gradually increases. At the same time, as the rotating shaft 2 rotates forward, the rotating shaft 2 drives the stud 12 to rotate through the meshing connection between the bevel gears 13. The stud 12 drives the sliding seat 6 to move along the sliding groove, indirectly driving the buffer seat 9 to approach the rotating shaft 2 and squeeze against it through the threaded connection. The telescopic end of the telescopic column 7 and the spring 8 are gradually compressed. After the angle of the automobile seat is adjusted, the adjusting lever 16 is released. Through the tensile elastic force of the tension spring 18, the adjusting lever 16 reversely rotates and resets around the axis of the driven shaft 15, so that the engaging teeth 17 are engaged with the gear 14, thereby locking the adjusted automobile seat. When the automobile seat is reset after the angle adjustment, the adjusting lever 16 is pulled to release the rotational limit of the rotating shaft 2. Subsequently, the internal torque of the scroll spring 4 causes the rotating shaft 2 to drive the seat frame 5 to reversely rotate and reset around its own axis. During this process, the compression elastic force of the spring 8 causes the buffer seat 9 to squeeze the outer side surface of the rotating shaft 2 that rotates synchronously with the seat frame 5, and the reset speed of the seat frame 5 is slowed down through the contact extrusion force. At the same time, as the seat frame 5 gradually resets, the rotating shaft 2 drives the sliding seat 6 to gradually move away from the rotating shaft 2 through the meshing connection between the bevel gears 13 and the threaded connection between the stud 12 and the sliding seat 6, thereby causing the reset extrusion buffer force exerted by the buffer seat 9 on the rotating shaft 2 to gradually decrease, so that the moving speed of the seat frame 5 is uniform during the reset buffering process. The rubber pad 10 increases the contact friction force, thereby improving the reset buffering effect of the buffer seat 9 on the rotating shaft 2.

[0025] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
