[0001] The invention relates to the technical field of automobile accessories, and in particular to a stepless adjustment locking mechanism with guides on both sides and a method thereof. Background Art

[0002] At present, the rotation function of passenger seats is widely used to meet the needs of passengers to adjust the seat angle to meet different usage requirements, such as but not limited to car seats.

[0003] The main components of the existing seat turntable include an upper turntable and a lower turntable that can rotate relatively, wherein the upper turntable is connected to the seat frame, and the lower turntable is connected to the seat slide rail or directly to the body; and a locking mechanism is provided between the upper and lower turntables for locking the upper turntable in the set working position.

[0004] However, there is a gap between the guide slider and the slide seat of the current locking structure. When the slider approaches the slide seat, the angle of the slider and the locking gear will be offset, making it impossible for the locking structure to completely lock the turntable. As a result, the seat can still shake slightly after the angle is adjusted, affecting the user experience. Summary of the invention

[0005] The purpose of the present invention is to provide a stepless adjustment locking mechanism and method with guides on both sides, aiming to solve the problem that the slider of the existing adjustment locking mechanism will cause the angle of the slider and the locking gear to shift when it approaches the slide seat, and the turntable cannot be completely locked. After the angle is adjusted, the seat can still shake slightly, affecting the user experience.

[0006] To achieve the above-mentioned objectives, in the first aspect, the present invention provides a stepless adjustment locking mechanism with two-side guides, comprising a chassis, a rotating disk, a transmission member and a locking assembly, wherein the rotating disk is rotatably arranged on the top of the chassis, the transmission member is arranged on one side of the rotating disk and the chassis, the locking assembly is arranged on one side of the rotating disk and the chassis, the locking assembly comprises a driving member, a locking wheel, a guide rail, a slide plate and a tension spring; the guide rail is fixedly connected to the chassis and is located on one side of the chassis, the driving member is arranged on the slide plate and one side of the chassis, the slide plate is slidably connected to the guide rail and is located in the guide rail, the tension spring is fixedly connected to the chassis and the slide plate and is fixedly connected to the slide plate and is located between the slide plate and the chassis, the locking wheel is meshed with the rotating disk and passes through the slide plate.

[0007] Wherein, the slide plate has a guide groove, and the guide groove is located on one side of the slide plate.

[0009] Wherein, the guide rail has a groove, and the groove is located at one side of the guide rail; the slide plate has a protrusion, and the protrusion is located at a side of the slide plate close to the guide rail.

[0010] Wherein, the transmission member includes a drive motor and a drive wheel, the drive motor is fixedly connected to the chassis and is located on a side of the chassis away from the rotating disk, the drive wheel is fixedly connected to the output end of the drive motor, meshes with the rotating disk, and is located on one side of the drive motor.

[0011] Wherein, the rotating disk includes a rotating disk and a gear ring, the rotating disk is rotatably connected to the chassis and is located on the top of the chassis, the gear ring is fixedly connected to the rotating disk, meshes with the driving wheel, and is located on one side of the rotating disk.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] See also Figures 1 to 5 In the first aspect, the present invention provides a stepless adjustment locking mechanism with two-side guide, including a chassis 1, a rotating disk 2, a transmission member 3 and a locking assembly 4, wherein the rotating disk 2 is rotatably arranged on the top of the chassis 1, the transmission member 3 is arranged on one side of the rotating disk 2 and the chassis 1, and the locking assembly 4 is arranged on one side of the rotating disk 2 and the chassis 1, and the locking assembly 4 includes a driving member 5, a locking wheel 6, a guide rail 7, a slide plate 8 and a tension spring 9; the guide rail 7 is fixedly connected to the chassis 1 and is located on one side of the chassis 1, the driving member 5 is arranged on one side of the slide plate 8 and the chassis 1, the slide plate 8 is slidably connected to the guide rail 7 and is located in the guide rail 7, the tension spring 9 is fixedly connected to the chassis 1 and fixedly connected to the slide plate 8, and is located between the slide plate 8 and the chassis 1, the locking wheel 6 is meshed with the rotating disk 2 and passes through the slide plate 8.

[0027] In the embodiment of the present invention, the driving member 5 is powered off, the tension spring 9 is reset and pulls the slide plate 8 to slide on the guide rail 7 and slide toward the outside of the chassis 1. At this time, the slide plate 8 slides to make the two locking wheels 6 move away from each other and separate from the gear ring 19, thereby unlocking the rotating disk 2. The transmission member 3 is powered on to drive the rotating disk 2, so that the rotating disk 2 rotates on the chassis 1, thereby adjusting the angle of the car seat. The driving member 5 drives the slide plate 8 to slide on the guide rail 7 and slide toward the inside of the chassis 1. , and stretches the tension spring 9. At this time, the slide plate 8 slides to make the two locking wheels 6 approach each other, and mesh with the rotating disk 2 to achieve mutual meshing among the three, thereby realizing stepless locking of the rotating disk 2 and complete locking of the rotating disk 2. This avoids the problem that the seat can still shake slightly after the locking mechanism is locked, and solves the problem that the slider of the existing adjustable locking mechanism will cause the angle of the slider and the locking gear to deviate when it approaches the slide seat, and the rotating disk cannot be completely locked. After the angle is adjusted, the seat can still shake slightly, affecting the user experience.

[0028] Furthermore, the slide plate 8 has a guide groove 10 , and the guide groove 10 is located on one side of the slide plate 8 .

[0029] In the embodiment of the present invention, the guide groove 10 is provided to guide the locking wheel 6 when the slide plate 8 is in motion, so as to prevent the two locking wheels 6 from moving out of position and causing the two locking wheels 6 to engage with the rotating disk 2.

[0031] In the embodiment of the present invention, the cable device 11 is powered to pull the rotating rod 12 , and while the rotating rod 12 rotates, the connecting piece 13 pulls the slide plate 8 to slide, so that the slide plate 8 slides in the guide rail 7 .

[0032] Furthermore, the guide rail 7 has a groove 14 , and the groove 14 is located on one side of the guide rail 7 . The slide plate 8 has a protrusion 15 , and the protrusion 15 is located on the side of the slide plate 8 close to the guide rail 7 .

[0033] In the embodiment of the present invention, when the slide plate 8 slides in the guide rail 7, the protrusion 15 on the slide plate 8 slides in the groove 14 in the guide rail 7. The groove 14 of the guide rail 7 limits the protrusion 15 to prevent the slide plate 8 from shifting left and right when sliding, thereby affecting the meshing effect of the locking wheel 6 and the rotating disk 2.

[0034] Furthermore, the transmission member 3 includes a drive motor 16 and a drive wheel 17. The drive motor 16 is fixedly connected to the chassis 1 and is located on a side of the chassis 1 away from the rotating disk 2.
