Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, and in particular relates to an inward opening structure with damping components. Background Technology

[0002] Traditional cars open by directly pulling the inner door handle. After the inner handle is unlocked, releasing it causes the handle to quickly return to its original position under the torque of a torsion spring, resulting in noticeable collision noise and abnormal sounds, which affects the riding experience. Therefore, this utility model proposes an inner opening structure with a damping component to solve the above problems. The inner opening structure with the damping component can avoid collision noise and meet the requirements of high-quality customers. Utility Model Content

[0003] This invention provides an internally open structure with a damping component, aiming to solve the problems mentioned in the background art.

[0004] This utility model is implemented as follows: an inwardly opening structure with a damping component, including a shell, a damping component, a handle, and a buffer pin;

[0005] The damping assembly includes a fixed end and a gear end. The housing is provided with a slot for fixing the fixed end. The housing is also provided with two oppositely distributed first through holes for installing a rotating shaft. The housing is also provided with a second through hole for installing the buffer pin.

[0006] The handle is rotatably connected to the housing via the pivot. The handle includes a gear and a boss. The gear is located on one side of the handle and meshes with the gear end of the damping assembly. The boss is located on the other side of the handle.

[0007] Preferably, the top surface of the boss is provided with a grid, and the bottom surface of the buffer nail is provided with a hemispherical protrusion, which is accommodated in the internal space of the grid.

[0008] Preferably, the handle is provided with two oppositely distributed third through holes, and the rotating shaft passes through the two third through holes.

[0009] Preferably, the outer wall of the rotating shaft is fitted with a bushing, and the outer wall of the bushing is fitted with a torsion spring. One end of the torsion spring is connected to the handle, and the other end is connected to the outer casing.

[0010] Preferably, the damping component has two oppositely distributed side ears on its fixed end, and the side ears are engaged and fixed with the slots in the housing.

[0011] Preferably, the gear end of the damping component includes a first gear and a shaft, the shaft is fixedly connected to the fixed end of the damping component, a damper is provided between the first gear and the shaft, and the first gear meshes with the gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Pulling the handle outward causes it to rotate around its pivot on the housing. This rotation of the handle's gear drives the first gear on the damping assembly to rotate, causing the handle's rotation to pull the rope and lock tongue, disengaging the lock tongue from the keyhole and unlocking the mechanism. Once unlocked, releasing the handle causes it to return to its original position under the action of a torsion spring. The handle's grille then impacts the protrusion on the buffer pin. Because the protrusion is made of rubber, it prevents the handle from impacting the housing, thus avoiding damage and noise. The damping assembly is secured to the housing via side ears and slots, simplifying assembly and saving manufacturing costs. The buffer pin installation is not only concealed but also space-saving. The first gear is rotatably connected to the shaft, with a damper between them. When the handle rotates, the gear drives the first gear, and the damper slows down the rotation, reducing vibration and impact and extending the handle's lifespan. Attached Figure Description

[0034] When in use, pull the handle end of handle 3 outward. At this time, handle 3 rotates on the outer shell 1 around the pivot 4. The gear 31 on handle 3 rotates, which drives the first gear on the gear end 23 of the damping assembly 2 to rotate. The rotation of handle 3 pulls the rope and the lock tongue to move. The lock tongue leaves the lock hole to unlock. After unlocking, release handle 3. Handle 3 returns to its original position under the action of torsion spring 6. At this time, the grille 33 on handle 3 will hit the protrusion 71 on the buffer pin 7. Since the protrusion 71 is made of rubber, it avoids the handle 3 hitting the outer shell 1, which would cause impact damage and abnormal noise.

[0035] In this embodiment, the damping component 2 is fixed to the slot 11 in the outer shell 1 by the side lug 22, which is simple to assemble and saves manufacturing costs; the buffer nail 7 in this application is not only concealed but also saves space.

The damper can slow down the rotation, reduce vibration and impact, and extend the service life of the handle 3.

[0045] The working principle and usage process of this utility model are as follows: When in use, the handle end of the handle 3 is pulled outward. At this time, the handle 3 rotates on the outer shell 1 around the pivot 4. The gear 31 on the handle 3 rotates, driving the first gear on the gear end 23 of the damping assembly 2 to rotate. The rotation of the handle 3 pulls the rope and the locking tongue to move, and the locking tongue leaves the lock hole to unlock. After unlocking, the handle 3 is released, and the handle 3 returns to its original position under the action of the torsion spring 6. At this time, the grille 33 on the handle 3 will hit the protrusion 71 on the buffer pin 7. Since the protrusion 71 is made of rubber, it avoids the handle 3 hitting the outer shell 1, which would cause impact damage and abnormal noise. The damping assembly 2 is fixed to the slot 11 in the outer shell 1 by the side ear 22, which is simple to assemble and saves manufacturing costs.
