DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, an electric angle adjuster with good sealing effect includes a closed ring 3, a movable disk 4, a fixed disk 8 and a drive shaft 11. The movable disk 4 and the fixed disk 8 are respectively provided with an upper gear ring and a lower gear ring on the upper and lower sides. The inner side of the fixed disk 8 is provided with an eccentric assembly. The lower side of the fixed disk 8 is provided with a sealing cover 9. The upper side of the sealing cover 9 is provided with two arc-shaped paddle positioning holes 902 and a spring positioning hole 901. The drive shaft 11 passes through the sealing cover 9, the fixed disk 8, the eccentric assembly 9 in sequence from bottom to top. Parts and a movable disk 4, a retaining spring 1 is provided at one end of the drive shaft 11 extending out of the movable disk 4, a spring 10 is provided on the lower side of the sealing cover 9, both ends of the spring 10 are located in the spring positioning hole 901, the spring 10 is inserted in the eccentric component, and two drive shaft paddles 112 are integrally formed on the upper side of the drive shaft 11 and are respectively inserted in two paddle positioning holes 902, and the drive shaft paddle 112 is inserted in the eccentric component so that the drive shaft 11 can drive the movable disk 4 to rotate through the eccentric component.

[0022] During installation, the staff inserts the two raised ends of the spring 10 into the spring positioning hole 901, then inserts the drive shaft paddle 112 into the paddle positioning hole 902, and clamps the spring 10 between the drive shaft 11 and the sealing cover 9, thereby positioning the spring 10 and the drive shaft 11, which improves the convenience of the staff when installing the sealing cover 9, and then successively sleeves the fixed disk 8 and the eccentric assembly on the shaft body 111 of the drive shaft 11, and then inserts the movable disk 4 into the eccentric assembly, and sleeves the closed ring 3 on the outer side of the movable disk 4, and finally uses the retaining spring 1 to prevent the drive shaft 11 from detaching from the movable disk 4, thereby simplifying the installation process of the electric adjuster and improving the staff's efficiency.

[0023] When in use, the output shaft of the driving motor is inserted into the driving shaft 11 and drives the driving shaft 11 to rotate, and then the driving shaft 11 drives the eccentric component to rotate. Under the action of the eccentric component, the inner gear ring on the lower side of the movable disk 4 is pushed to rotate eccentrically along the outer gear ring on the upper side of the fixed disk 8, thereby adjusting the angle of the car seat. When not in use, under the action of the spring 10, the eccentric component drives the movable disk 4 to be concentric with the fixed disk 8, and then the lower gear ring of the movable disk 4 is meshed with the upper gear ring of the fixed disk 8, so that the angle of the car seat cannot be adjusted.

[0024] In this embodiment, the two paddle positioning holes 902 and the spring positioning hole 901 are arranged in a circular array on the upper side of the sealing cover 9 .

[0025] In this embodiment, the eccentric assembly includes a bushing 7, a turning ring 6 and two wedge blocks 5. The upper side of the sealing cover 9 is provided with an annular groove 903. The bushing 7 is inserted into the annular groove 903, and the outer side of the bushing 7 is in contact with the inner side of the fixed plate 8. The turning ring 6 is located on the inner side of the bushing 7, and a gap is left between the turning ring 6 and the bushing 7. The two wedge blocks 5 are symmetrically inserted in the insertion. There is space at the opposite ends of the two wedge blocks 5 so that the two wedge blocks 5 can move in the gap. The outer side of the turning ring 6 is provided with a step in contact with the wedge blocks 5. The upper and lower sides of the wedge blocks 5 are provided with a plug-in hole plugged into one end of the spring 10 extending out of the spring positioning hole 901. The drive shaft paddle 112 extends out of the paddle positioning hole 90 One end of 2 contacts with the side of the wedge block 5. When in use, the driving shaft 11 drives the sealing cover 9 and the spring 10 to rotate, so that the opposite sides of the two wedge blocks 5 contact each other, and drives the wedge block 5 to push the movable plate 4 to make the movable plate 4 eccentric with the fixed plate 8, so that the lower gear ring of the movable plate 4 and the upper gear ring of the fixed plate 8 are misaligned. Then, under the action of the driving shaft 11, the wedge block 5 and the turning ring 6 drive the movable plate 4 to rotate eccentrically on the fixed plate 8, thereby realizing the angle adjustment of the car seat. When the car seat does not rotate, the wedge block 5 moves toward each other under the action of the spring 10, so that the movable plate 4 is concentric with the fixed plate 8, and the inner gear ring of the movable plate 4 is meshed with the outer gear ring of the fixed plate 8, so that the movable plate 4 cannot rotate, thereby improving the stability of the car seat.

[0026] In this embodiment, a protrusion is integrally formed on the inner side of the paddle positioning hole 902, and the protrusion conflicts with the drive shaft paddle 112. When in use, the output shaft of the drive motor is inserted into the drive shaft 11, and the drive motor drives the drive shaft 11 to rotate. The drive shaft paddle 112 can push the protrusion, thereby rotating the sealing cover 9.

[0027] In this embodiment, a washer 2 in contact with the upper side of the movable disk 4 is provided on the lower side of the retaining spring 1. When in use, the washer 2 can prevent the retaining spring 1 from rubbing against the upper side of the movable disk 4, thereby increasing the service life of the retaining spring 1.

[0028] In this embodiment, the lower side of the sealing cover 9 has three arc-shaped drive shaft limiting grooves 904 in a circular array, and the lower side of the drive shaft 11 has an arc-shaped protrusion 113 integrally formed thereon and inserted into the drive shaft limiting groove 904. When in use, the arc-shaped protrusion 113 is inserted into the drive shaft limiting groove 904 to position the drive shaft 11, thereby improving the convenience of connecting the drive shaft 11 to the sealing cover 9.

[0029] In this embodiment, the sealing cover 9 is made of plastic. When in use, the sealing cover 9 is made of plastic to reduce the overall weight of the electric recliner, making the electric recliner more lightweight.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
