Description

Technical Field

[0001] This utility model relates to a core component of an angle adjuster, and more particularly to a core component of a miniature electric angle adjuster, which belongs to the field of automotive angle adjuster technology. Background Technology

[0002] A car seat adjuster is a component installed on a car seat to lock or unlock the seat back or adjust its angle. Existing adjusters are relatively large, with an outer diameter generally exceeding 70mm. Their bulky size limits space and makes them unsuitable for the lightweight requirements of new energy vehicles.

[0003] Therefore, it is particularly necessary to provide a core component of the angle adjuster that has a compact and reasonable structural design, is lightweight, and is not limited by space. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and provide a core component of a miniature electric angle adjuster that is compact and reasonable in structure, safe and reliable, lightweight, widely applicable, and not limited by space.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: The core component of this miniature electric angle adjuster includes a retaining ring, an inner gear disk, and an outer gear disk. The retaining ring is slidably matched with the inner gear disk, and the outer gear disk is fixed with the retaining ring. The feature is that it also includes a drive wheel, a wedge block, and a spring. The drive wheel cooperates with the inner gear disk, and the inner gear disk meshes with the outer gear disk. The wedge block includes a matching half-wedge block one and a half-wedge block two. The half-wedge block one and the half-wedge block two are respectively arranged in the eccentric arc-shaped space formed after the inner gear disk and the outer gear disk mesh. The spring is arranged in the wedge block so that the half-wedge block one and the half-wedge block two wed the inner gear disk and the outer gear disk tightly.

[0006] Preferably, the present invention also includes a retaining ring, wherein the drive wheel passes through the internal gear disc and is locked by the retaining ring.

[0007] Preferably, the present invention also includes a positioning boss, wherein the internal gear plate is provided with a positioning boss for positioning and welding of the external connecting plate.

[0008] Preferably, the present invention also includes an inner ring outer surface and an outer gear disk inner ring, wherein the inner gear disk and the outer gear disk are engaged with a difference of one tooth, so that the inner ring outer surface on the inner gear disk and the outer gear disk inner ring on the outer gear disk are eccentrically set.

[0009] Preferably, the drive wheel of this invention is made of plastic.

[0010] Preferably, the external gear disc of this invention is welded to the retaining ring.

[0011] Compared with the prior art, this utility model has the following advantages and effects: (1) The overall structure is compact and reasonable, stable and reliable, the core components are lightweight, and the adaptability is wide and not limited by space; (2) The outer ring and the outer gear plate are laser welded, which makes the overall volume smaller and meets the requirements of lightweight use.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] Example

[0019] See Figures 1 to 4 The core components of the miniature electric angle adjuster in this embodiment include a retaining ring 1, an inner gear plate 2, an outer gear plate 5, a retaining ring 4, a drive wheel 3, a wedge block 6, and a spring 7. The retaining ring 1 is slidably matched with the inner gear plate 2, the outer gear plate 5 is fixed with the retaining ring 1, the drive wheel 3 cooperates with the inner gear plate 2, and the inner gear plate 2 meshes with the outer gear plate 5.

[0020] In this embodiment, the wedge block 6 includes a first half-wedge block 61 and a second half-wedge block 62 that match each other. The first half-wedge block 61 and the second half-wedge block 62 are respectively disposed in the eccentric arc-shaped space formed after the inner gear disk 2 and the outer gear disk 5 are meshed. The spring 7 is disposed in the wedge block 6 so that the first half-wedge block 61 and the second half-wedge block 62 wedge the inner gear disk 2 and the outer gear disk 5 tightly.

[0021] In this embodiment, the drive wheel 3 is connected to the internal gear disk 2 and locked by the retaining ring 4.

[0022] In this embodiment, the internal gear plate 2 is provided with a positioning boss 21 for positioning and welding of the external connecting plate.

[0023] In this embodiment, the inner gear disk 2 and the outer gear disk 5 are engaged with one tooth difference, so that the positioning boss 21 on the inner gear disk 2 and the outer gear disk inner ring 51 on the outer gear disk 5 are eccentrically set.

[0024] In this embodiment, the drive wheel 3 is made of plastic; the outer gear disc 5 is welded to the ring 1.

[0025] In this embodiment, "one tooth difference" means that the inner toothed disk 2 has 34 teeth and the outer toothed disk 5 has 33 teeth, meaning that the two mesh with each other by one tooth.

[0026] During operation, the drive wheel 3 is rotated by the external spline shaft, and the protrusion 31 pushes the end face of the wedge block 6 to rotate, which in turn drives the outer gear disk 5 to rotate and mesh with the inner gear disk 2. If the reverse is reversed, the principle is the same as above.

[0027] The existing wedge block 6 structure requires an additional eccentric wheel, which makes the overall size larger.

[0028] The existing drive wheel 3 structure uses metal parts and requires a buffer pad, which increases the cost and makes the overall structure relatively complex.

[0029] Based on the above description, those skilled in the art are already able to implement it.

[0030] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, all of which should fall within the protection scope of this utility model.
