[0002] An angle adjuster is a device installed on an automobile seat to realize the angle adjustment of the seat back. Generally, the device is composed of a backrest connecting plate, a seat connecting plate, a core component, a handwheel or an adjustment handle, a return spring and other parts. In some low-cost seats, the backrest connecting plate and the seat connecting plate are generally integrated into the backrest frame and the seat frame.

[0003] After retrieval, the patent (application number: 201821716176.7) discloses an "angle adjustment device for the assembly of an automobile seat frame". When the device is used, the handle is pulled obliquely upward to drive the clamping plate to rotate counterclockwise, so as to pull the first spring to rotate counterclockwise. When the first spring is stressed, under the action of the clamping plate bolt, the first spring is prevented from separating from the clamping plate, ensuring the normal progress of the angle adjustment work and improving the use stability. However, the device has the following problems when in use:

[0004] First of all, the entire angle adjustment device is mainly controlled by a first spring. Once the elasticity of the first spring weakens, the clamping position between the first spring and the clamping plate will fail, thereby reducing the service life of the adjuster.

[0005] In addition, the core components inside the angle adjustment device will rust after a period of use, resulting in a jamming phenomenon and affecting the comfort of the angle adjustment process. Content of the Utility Model

[0011] Preferably, a handle is installed on the outer wall of one side of the central traction plate, and a first spring is connected between the handle and the angle adjustment disc.

[0012] Preferably, the outer wall of the other side of the central traction plate is fixedly connected by bolts with a protective housing, and the first spring is arranged inside the protective housing.

[0013] Preferably, a plurality of fixing frames are welded on the outer wall of one side of the angle adjustment disc at equal intervals. A second spring is connected to the inner wall of the fixing frame, and one end of the second spring is connected to the outer wall of a slider, and the slider is welded to the outer wall of the limiting block.

[0014] Preferably, a side ring is welded on the outer wall of one side of the angle adjustment disc outside the rotating gear disc.

[0015] Preferably, a first set of teeth is arranged on the outer wall of one side of the limiting block, and a second set of teeth is arranged on the inner wall of the rotating gear disc.

[0016] Preferably, the bottom of the outer wall of the other side of the angle adjustment disc is fixedly connected by bolts with a seat connecting plate.

Each return spring 3 can provide a pulling force to avoid the problem of jamming failure caused by the decrease in the acting force between the return spring 3 and the central traction plate 2, with a high error tolerance. And a plurality of limit blocks 4 can simultaneously hold the rotating gear disc 5 to avoid the shaking of the rotating gear disc 5, with high stability.

[0030] Embodiment 2, referring to Figures 1 to 3, An angle adjustment device for assembling an automotive seat frame. On the outer wall of one side of two angle adjustment discs 1, there is a rotating gear disc 5, and a rotating column 6 is fixedly connected between the two rotating gear discs 5. One end of the outer wall of the rotating column 6 is fixedly connected with a speed reducer 7, and a servo motor 8 is installed on the outer wall of one side of the speed reducer 7.

[0031] In this embodiment, a set of automatic angle adjustment structures is added between the two angle adjustment discs 1. The servo motor 8 drives the gears inside the speed reducer 7 to rotate, thereby controlling the rotation of the rotating column 6. Since both ends of the rotating column 6 are fixedly connected to the rotating gear disc 5, when the rotating column 6 rotates, the rotating gear disc 5 will also rotate together, realizing the automatic angle adjustment of the automotive seat frame, saving manpower and being convenient to operate.

[0032] Embodiment Three, referring to Figure 1 , An angle adjustment device for assembling an automotive seat frame. On the outer wall of the other side of the angle adjustment disc 1, there is an oil injection pipe 9 connected, and an oil injection bottle 10 is screwed on the outer wall of one end of the oil injection pipe 9.

[0033] In this embodiment, two sets of lubrication structures are added. In the state of inflexible adjustment, the oil injection bottle can be screwed into the oil injection pipe 9, and the lubricating oil 10 can be injected into the angle adjustment disc 1 and the rotating gear disc 5 by squeezing the oil injection bottle 10, thereby lubricating the core components, avoiding the problem of rust, and improving the comfort of the operator during the angle adjustment process.

[0034] Referring to Figures 2 to 3 , A handle 11 is installed on the outer wall of one side of the central traction plate 2, and a first spring 12 is connected between the handle 11 and the angle adjustment disc 1.

[0035] Referring to Figure 3 , On the outer wall of the other side of the central traction plate 2, a protective housing 13 is fixedly connected by bolts, and the first spring 12 is arranged inside the protective housing 13.

[0036] Referring to Figure 4 , On the outer wall of one side of the angle adjustment disc 1, there are equally spaced fixed frames 14 welded.

[0040] Reference Figures 1 to 3 As shown in Figures 1 to 3 , one outer wall of one side of the rotary gear disc 5 is fixedly connected with a chair back connecting plate 21 through bolts.

[0041] Working principle: The seat connecting plate 20 and the chair back connecting plate 21 are respectively fixed to the seat and the chair back. When the handle 11 is pressed down, the central traction plate 2 can be controlled to rotate, thereby reducing the force between the central traction plate 2 and the limit block 4. Under the action of the second spring 15, the limit block will move closer to the center of the angle adjustment disc 1, so that the first set of teeth 18 and the second set of teeth 19 are separated, canceling the force on the rotary gear disc 5, enabling the rotary gear disc 5 at both ends of the rotating column 6 to rotate when the servo motor 8 drives the gear inside the reducer 7 to rotate. Finally, the automatic angle adjustment of the automobile seat frame is realized. If it feels not smooth during the angle adjustment process, the oil injection bottle 10 can be screwed into the oil injection pipe 9, and the lubricating oil can be injected into the angle adjustment disc 1 and the rotary gear disc 5 by squeezing the oil injection bottle 10 to lubricate the core components.
