[0020] Example 1: As Figures 1-3 As shown, a rebound latch buffer ejection mechanism for a sliding door lock includes a rebounder 2 and a housing 1 for mounting the rebounder 2. In actual production and use, the housing 1 can be a split structure with upper and lower sections. The rebounder 2 is a key component that links with the latch and other parts; it is a mature technology and will not be elaborated or limited here. The rebounder 2 performs linear reciprocating motion along the axial direction. The housing 1 is provided with a damping component and a mounting groove 3 for mounting the damping component. The rebounder 2 and the housing 1 are connected by the damping component and undergo a transmission that tends towards relative stillness. The damping component is linked to the rebounder 2, and frictional resistance is formed through surface contact between the damping component and the housing 1. The rebounder 2 and the housing 1 tend to be relatively still; this point is achieved by the damping component to dissipate kinetic energy, which can be through the transfer of frictional resistance or other forms. In this embodiment, it is mainly achieved through surface contact.
[0021] The damping assembly includes a damping gear 4, an isolation pad 5, and a damping element 6. Since the linear motion and rotating structure of the rebounder 2 allow for full space utilization, the gear is designed to change the transmission direction, resulting in a simple and effective structure that meets design requirements. The isolation pad 5 provides isolation and protection, and also reduces wear and tear on related components. The damping element 6 is the main component responsible for damping and deceleration; in this embodiment, it increases frictional resistance through multi-faceted contact.
[0022] The rebounder 2 has a rack 7 arranged axially, which meshes with a damping gear 4. The damping gear 4 has a connecting part 8 that passes through an isolation gasket 5 and rotates circumferentially with the damping element 6. The rack 7 and the rebounder 2 are an integral structure, making the machining of the rack 7 relatively convenient and meeting design requirements, converting linear motion into rotational motion. The rigid connection between the connecting part 8 and the damping element 6 achieves simple and reliable transmission, preventing unnecessary losses during transmission and thus avoiding localized damage to components.
[0023] The damping element 6 has a circumferentially arranged damping portion 9 on its outer wall, which provides multi-point contact for frictional damping. The bottom surface of the damping portion 9 has an inner open ring 10 near the axis of the damping element 6, and an outer open ring 11 away from the axis of the damping element 6. Damping rings, such as rubber rings or other matching components, can be provided at the inner and outer open rings 10 and 11, but are not limited to these. The mounting groove 3 has a stepped structure. In this embodiment, damping rings can be omitted, and the outer open ring 11 or the inner open ring 10 can overlap the mounting groove 3 wall to further increase the contact area and improve frictional resistance. Regardless of the method used, the damping effect is improved by increasing the contact area, and is not limited to surface roughness.
[0024] The end of the connecting part 8 has an elliptical straight structure, and the damping member 6 has a connecting groove 12 in the center corresponding to the size and shape of the end of the connecting part 8. The elliptical straight structure means that the two ends are semicircular and the middle section is rectangular, which facilitates rigid connection and linkage. The damping part 9 has a protruding contact end 13 between the inner open ring 10 and the outer open ring 11, and the mounting groove 3 has limiting grooves spaced along the circumferential direction. The contact end 13 and the side wall of the damping member 6 can both be the main contact surfaces, depending on the actual production use. The spacing between the limiting grooves is uniform or gradually decreases in the circumferential direction. This mainly describes that the layout of the damping effect is uniform, or gradually increases or decreases in one direction, and will not be elaborated or limited in detail here.
[0025] Example 2: Different from Example 1, such as Figures 4-5As shown, the rebounder 2 in this embodiment is a split structure, which is beneficial for the design and installation of the limiting and linkage assembly structure. If the one-way locking linkage structure is integrated into the split part of the rebounder 2, the one-way locking structure is a mature technical means, which is realized by non-linear movement and reverse blocking, and will not be elaborated or limited here.
