Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, and in particular to a mounting structure for a handle gear damper. Background Technology

[0002] In automotive interior components, parts such as door handles often require integrated gear dampers to achieve smooth reset or cushioning functions. Traditional gear damper mounting structures mostly use screw fastening or snap-fit ​​rigid assembly, which has problems such as complex assembly processes, difficult disassembly and maintenance, and susceptibility to loosening or damage due to vibration. Especially in the space-constrained interior of car doors, complex mounting structures increase the difficulty of component layout and assembly costs. Although some structures attempt to simplify installation, they often lack reliable limit and stop designs, causing the gear damper to be prone to displacement, deflection, or detachment under long-term use or impact, affecting functional stability and service life. Therefore, there is an urgent need for a compact, easy-to-install, and securely locked gear damper mounting solution to meet the stringent requirements of automotive components for high reliability, ease of maintenance, and assembly efficiency. Utility Model Content

[0003] Technical problems to be solved The technical problem to be solved by this utility model is to provide a mounting structure for a lever gear damper that optimizes the installation process and enables quick assembly with one hand while ensuring a compact structure and secure installation. Technical solution The technical solution adopted by this utility model to solve the above problems is: A mounting structure for a lever-type gear damper is characterized by comprising a mounting base and a gear damper mounted on the mounting base; the mounting base includes an elastic slide rail for guiding the gear damper into place and a mounting area for limiting the position of the mounted gear damper; the mounting area includes an axial limiting surface for axially limiting the gear damper and a circumferential anti-rotation surface for circumferentially limiting the gear damper; the gear damper includes an anti-rotation mating surface and a limiting mating surface; the anti-rotation mating surface of the gear damper mates with the circumferential anti-rotation surface of the mounting area, and the limiting mating surface of the gear damper mates with the axial limiting surface of the mounting area.

[0004] In the above technical solution, the gear damper slides into the installation area along the elastic slide rail and cooperates with the axial limiting surface and the circumferential anti-rotation surface of the installation area. The circumferential anti-rotation surface prevents the gear damper from circumferentially deflecting after installation, and the axial limiting surface can limit the axial displacement of the gear damper.

[0005] Furthermore, the elastic slide rail is provided with an inlet end and an outlet end at both ends; the elastic slide rail is curved, and the height of the inlet end is higher than that of the outlet end, with the height of the protrusion relative to the top end face of the mounting base as a reference.

[0006] In the above technical solution, the elastic slide rail is set as a single helix, which can extend the stroke as much as possible within a limited area, and make the installation path of the gear damper smoother. In addition, the elastic slide rail itself has a certain elasticity, which can reduce the wear of the gear damper during the installation process.

[0007] Furthermore, a mounting hole is provided at the center of the end face of the mounting base; the gear damper also includes a mounting post and a connecting gear connected sequentially from top to bottom; when the gear damper is installed in the mounting base, the mounting post mates with the mounting hole, and the connecting gear meshes with external equipment.

[0008] Furthermore, the gear damper has a first mounting plate and a second mounting plate that are integrally formed and symmetrically extended from both sides; the anti-rotation mating surface includes a first anti-rotation mating surface on the first mounting plate and a second anti-rotation mating surface on the second mounting plate.

[0009] In the above technical solution, the first anti-rotation mating surface and the second anti-rotation mating surface are symmetrically arranged, the sides of the first mounting plate are all set as the first anti-rotation mating surface, and the sides of the second mounting plate are all set as the second anti-rotation mating surface.

[0010] Furthermore, the limiting mating surface of the gear damper includes a first limiting mating surface and a second limiting mating surface; the top end face of the first mounting plate is set as the first limiting mating surface; and the top end face of the second mounting plate is set as the second limiting mating surface.

[0011] In the above technical solution, the first anti-rotation mating surface is connected to the first limiting mating surface, and the first anti-rotation mating surface is perpendicular to the first limiting mating surface; the second anti-rotation mating surface is connected to the second limiting mating surface, and the second anti-rotation mating surface is perpendicular to the second limiting mating surface.

[0012] Furthermore, the circumferential anti-rotation surface includes a first circumferential anti-rotation surface and a second circumferential anti-rotation surface; the first circumferential anti-rotation surface mates with a first anti-rotation mating surface, and the second circumferential anti-rotation surface mates with a second anti-rotation mating surface; the second circumferential anti-rotation surface is provided with an upward protrusion on the side of the mounting base near the second axial limiting surface, and the first circumferential anti-rotation surface is provided on the side of the elastic slide rail near the first axial limiting surface.

[0013] In the above technical solution, the first circumferential anti-rotation surface and the second circumferential anti-rotation surface can prevent the gear damper from circumferentially deflecting after installation.

[0014] Furthermore, the axial limiting surface includes a first axial limiting surface and a second axial limiting surface, the first axial limiting surface mates with a first limiting mating surface, and the second axial limiting surface mates with a second limiting mating surface; the mounting base protrudes upward and bends toward the gear damper to form the second axial limiting surface; a support wall is provided on the opposite side of the mounting base to the second axial limiting surface, and the support wall protrudes toward the second axial limiting surface to form the first axial limiting surface.

[0015] In the above technical solution, after the first axial limiting surface mates with the first limiting mating surface, it can prevent one side of the first limiting mating surface of the gear damper from tilting up; after the second axial limiting surface mates with the second limiting mating surface, it can prevent one side of the second limiting mating surface of the gear damper from tilting up; when both sides of the gear damper mate with the axial limiting surface, the axial displacement of the gear damper can be restricted.

[0016] Furthermore, one end of the support wall extends toward the second axial limiting surface to form a support rod for supporting the elastic slide rail.

[0017] In the above technical solution, the support rod is set perpendicular to the support wall.

[0018] Furthermore, the end of the elastic slide rail is connected to the top of the first circumferential anti-rotation surface of the circumferential anti-rotation surface.

[0019] In the above technical solution, the first mounting plate of the gear damper slides into the mounting seat along the elastic slide rail. After the first mounting plate has completed the travel of the elastic slide rail, it enters the mounting area and cooperates with the first axial limiting surface and the first circumferential anti-rotation surface of the mounting area. At this time, the second mounting plate also enters the mounting area and cooperates with the second circumferential anti-rotation surface and the second axial limiting surface in the mounting area. Beneficial effects Compared with the prior art, the technical solution of this utility model has the following advantages: The present invention provides a mounting structure for a handle gear damper, wherein the elastic slide rail is designed as a spiral slide, and the gear damper can rotate and slide into the mounting area along a predetermined path, enabling quick assembly with one hand. By utilizing the dual cooperation of symmetrically distributed limiting surfaces and anti-rotation surfaces, the axial displacement and circumferential deflection of the gear damper are limited in a vibration environment, ensuring the stability of the door handle during long-term use.
