Abstract
Description
Technical Field
[0001] This utility model relates to the automotive field, and in particular to a metal insert damping sleeve structure. Background Technology
[0002] With the development of conference systems, vehicle systems and smart home technologies, ceiling-mounted flip screens are increasingly widely used in various display terminal applications due to their advantages of being aesthetically pleasing, space-saving, and easy to hide. In this type of flip mechanism, the automatic flipping of the screen is usually achieved by a motor driving a linkage system.
[0003] To achieve smooth and reliable tilting motion, damping devices are often introduced into the tilting mechanism to reduce impact, mitigate vibration, and extend the overall service life of the machine. Currently, the common approach is to install damping components, such as damping plates, rubber washers, or nylon sleeves, between moving connecting parts. However, plastic damping elements are prone to fatigue damage due to long-term friction or high loads; furthermore, some structures require fixing via adhesive bonding or heat fusion, which is not only inefficient but also raises reliability issues.
[0004] Therefore, there is an urgent need for a damping structure with high structural strength, stable damping performance, and reliable assembly on metal parts to improve the overall performance and service life of the ceiling-mounted screen flip mechanism. Summary of the Invention
[0005] The purpose of this utility model is to overcome the defects of the prior art by providing a metal insert damping sleeve structure, which solves the problem of fatigue damage of plastic damping elements due to long-term friction or high load.
[0006] The technical solution of this utility model is: a metal insert damping sleeve structure, including a damping sleeve, a metal sleeve nested on the outer periphery of the damping sleeve, and the metal sleeve and the damping sleeve being coaxially arranged.
[0007] Using the above technical solution, the damping sleeve has a hollow structure and a notch is provided on the damping sleeve, which extends through the damping sleeve from top to bottom.
[0008] A further feature of this invention is that the damping sleeve is provided with a positioning stake located directly opposite the notch, and the length of the positioning stake is the same as the length of the notch; there are two positioning stakes in total, and there is a gap between the positioning stakes.
[0009] With the above further configuration, the positioning pile also includes an annular surface located between the positioning pile and one end of the notch; and the end face of the positioning pile is wedge-shaped.
[0010] A further feature of this invention is that a fixed pile and a wedge-shaped pile are arranged in a ring on the annular surface; the wedge-shaped end of the wedge-shaped pile is seamlessly connected to one end of the damping sleeve.
[0011] With the above further configuration, several pairs of semi-cylinders are also arranged in a ring on the annular surface, with the arc surfaces of each pair of semi-cylinders facing opposite directions.
[0012] A further feature of this invention is that the end of the damping sleeve is also provided with a plurality of outward flaps in a ring shape, and the end of the positioning pile is connected to one of the outward flaps.
[0013] With the above-described further configuration, one end of the metal sleeve is connected to the outer flap, and the other end of the metal sleeve is connected to the end face of the wedge-shaped pile.
[0014] A further feature of this invention is that the metal sleeve is provided with a groove for nesting with the fixed pile and a positioning groove for sliding with the semi-cylinder; one end of the positioning groove is a wedge-shaped notch, and the other end is an arc-shaped surface that abuts against the semi-cylinder.
[0015] Furthermore, the metal sleeve is further provided with a notch that matches the width of the positioning stake.
[0016] In summary, this application includes at least one of the following beneficial technical effects: By integrating metal inserts inside the damping sleeve, the mechanical strength of the overall structure is significantly improved, preventing plastic deformation caused by long-term rotation or loading, which is particularly suitable for high-frequency flipping conditions. The damping sleeve is made of high wear-resistant and high-resilience rubber or TPU material with an interference fit to the metal insert, which can provide a long-lasting and stable rotational resistance during shaft rotation, reduce mechanical impact, reduce noise, and improve user experience; The encapsulation structure between the metal insert and the damping sleeve prevents axial or radial loosening during operation, ensuring the stability and accuracy of the tilting mechanism.

[0023] like Figure 1-4 As shown, the metal insert damping sleeve structure includes a damping sleeve 1, and a metal sleeve 2 is nested around the outer periphery of the damping sleeve 1. The metal sleeve 2 and the damping sleeve 1 are coaxially arranged.
[0024] The damping sleeve 1 is made of highly elastic, wear-resistant rubber or TPU material, and is sleeve-shaped. It is used to fit on the rotating shaft to provide cushioning and shock absorption.
[0025] The metal sleeve 2 is located outside the damping sleeve 1 and is fixedly connected to the damping sleeve by means of covering or interference fit to prevent the damping sleeve from sliding or deforming due to shear force during use.
[0026] Specifically, the damping sleeve 1 has a hollow structure and a notch 11 is provided on the damping sleeve 1, which extends through the damping sleeve 1 from top to bottom.
[0027] The damping sleeve 1 is also provided with a positioning stake 12 located directly opposite the notch 11, and the length of the positioning stake 12 is the same as the length of the notch 11. There are two positioning stakes 12, and there is a gap 13 between the positioning stakes 12.
[0028] The positioning pile 12 also includes an annular surface 14 located between the positioning pile 12 and one end of the notch 11; and the end face of the positioning pile 12 is wedge-shaped.
[0029] Fixed piles 141 and wedge-shaped piles 142 are arranged in a ring on the annular surface 14; The wedge end of the wedge pile 142 is seamlessly connected to one end of the damping sleeve 1.
[0030] Several pairs of semi-cylinders 143 are also arranged in a ring on the annular surface 14, with the arc surfaces of each pair of semi-cylinders 143 facing opposite directions.
[0031] The end of the damping sleeve 1 is also provided with several outward flaps 15 in a ring, and the end of the positioning pile 12 is connected to one of the outward flaps 15.
[0032] One end of the metal sleeve 2 is connected to the outer flap 15, and the other end of the metal sleeve 2 is connected to the end face of the wedge-shaped pile 142.
[0033] The metal sleeve 2 is provided with a slot 21 that nests with the fixed pile 141 and a positioning slot 22 that slides with the semi-cylinder 143; One end of the positioning groove 22 is a wedge-shaped notch, and the other end is an arc-shaped surface that abuts against the semi-cylinder 143.
[0034] The metal sleeve 2 is also provided with a notch 23 that matches the width of the positioning stake 12.
[0035] The damping sleeve 1 is fitted onto the rotating shaft or rotating pin of the flipping mechanism; the metal sleeve 2 is fastened to the outside of the damping sleeve by molding or press fitting to form an integrated structure; the damping structure is inserted into the positioning hole of the bracket as a whole. When the motor drives the flipping mechanism to rotate, the rotating shaft drives the damping sleeve to rotate slowly. The damping material provides a gentle friction force to achieve buffer deceleration; the metal sleeve provides rigid support to ensure the stable operation and durable use of the entire structure.
[0036] It is worth noting that the metal sleeve 1 can be made of stainless steel, aluminum alloy or other high-strength alloy materials; the damping sleeve 2 can be made of different types such as rubber, TPU, silicone, etc., depending on the usage environment, and its structure can also be embedded, external or assembled separately.
