Description

Technical Field

[0001] The utility model relates to the technical field of luggage compartment door buffering, in particular to a silent buffer block for a car luggage compartment door. Background Art

[0002] A car luggage compartment door usually refers to the opening at the rear of the car for storing or accessing luggage or other items. It is part of the car body structure and usually opens upwards, but sometimes it may be a side-opening or hatchback design, depending on the design of the car model.

[0003] The silent buffer block for the luggage compartment door of a car is a device installed on the edge of the luggage compartment door. Its main function is to reduce the impact force and noise when the door is closed. Its main features are: Buffering effect: When the luggage compartment door is closed, the buffer block can absorb and disperse the impact force, preventing hard collisions from causing damage to the vehicle body structure; Silent effect: The buffer block is usually made of materials with sound-absorbing and shock-absorbing properties, such as rubber or polyurethane. These materials can effectively reduce the noise generated when the door is closed; Comfort: Using a silent buffer block can make the closing process of the luggage compartment door smoother, improving the user's operating experience;

[0004] When the existing silent buffer block is in use, when the luggage compartment door is closed, the silent buffer block will be in a squeezed state for a long time. Although the silent buffer block is made of elastic material, it is easy to lose some elasticity due to material fatigue when used for a long time or when the silent buffer block is not frequently allowed to rebound. This not only reduces the quieting and shock-absorbing effects of the silent buffer block, but also affects the service life of the silent buffer block.

[0005] In order to solve the above problems, the present application proposes a silent buffer block for a car luggage compartment door. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a silent buffer block for a car luggage compartment door, which can keep the silent buffer block body in an effective shape and function.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a silent buffer block for a car luggage compartment door, comprising an externally threaded column, the top of the externally threaded column is fixedly connected to a silent buffer block body, a fixing rod is slidably connected to the middle of the upper interior of the silent buffer block body, the top of the fixing rod is fixedly connected to a buffer head, the bottom end of the fixing rod is fixedly connected to a first rubber disc, a groove is provided on the inner side of the first rubber disc, a compression spring is fixedly connected above the groove on the inner side of the first rubber disc, the end of the compression spring away from the first rubber disc is fixedly connected to a second rubber disc, limiting grooves are provided on the edges of the first rubber disc and the second rubber disc, damping rings are provided on the edges of the first rubber disc and the second rubber disc, and an adhesive layer is provided on the inner side of the damping ring.

[0008] As a preferred silent buffer block for a car luggage compartment door of the utility model, the bottom of the buffer head contacts the top of the silent buffer block body, the top of the second rubber disc contacts the upper inside of the silent buffer block body, the bottom of the second rubber disc contacts the lower inside of the silent buffer block body, and a groove identical to the inner side of the first rubber disc is provided on the upper inside of the second rubber disc. When the car luggage compartment door is closed, the compression spring between the first rubber disc and the second rubber disc in the silent buffer block body can not only absorb and disperse the impact force generated when closing the door, but also reduce damage to the vehicle body structure.

[0009] As a preferred silent buffer block for a car luggage compartment door of the utility model, the external threaded column is fixed at an internal position of the car luggage compartment door by a spiral manner, and the silent buffer block body and the buffer block are located on the outside of the car luggage compartment door. The buffer head contacts the rear of the car frame when the car luggage compartment door is closed, so that the silent buffer block body is fixed to the outside of the car luggage compartment door by the external threaded column to achieve a shock-absorbing and silent effect.

[0010] As a preferred silent buffer block for a car luggage compartment door of the utility model, a through hole is opened in the upper middle of the interior of the silent buffer block body, and the diameter of the through hole in the upper middle of the interior of the silent buffer block body matches the cross-sectional diameter of the fixing rod. The length of the fixing rod is the same as the distance between the first rubber disc and the second rubber disc, so that when the buffer head is subjected to pressure and slides, the first rubber disc inside the silent buffer block body is driven to move toward the position of the second rubber disc.

[0011] As a preferred silent buffer block for a car luggage compartment door of the utility model, the number of the compression springs is two groups, and the compression springs are distributed on the inner sides of the grooves on the left and right sides of the first rubber disc and the second rubber disc. The rebound force of the compression springs is greater than the rebound force of the silent buffer block body. Driven by the compression springs, the first rubber disc and the second rubber disc can quickly return to their original shape after being compressed, so that the silent buffer block body maintains an effective shape and function, thereby improving the service life of the silent buffer block body to a certain extent.

[0012] As a preferred silent buffer block for a car luggage compartment door of the utility model, the limiting groove is arranged in an annular shape at the edge of the first rubber disc and the second rubber disc, and the height and width of the limiting groove are matched with the height and wall thickness of the damping ring. The damping ring can increase the friction force of the first rubber disc and the second rubber disc when sliding inside the silent buffer block body, thereby increasing the resistance.

[0013] As a preferred silent buffer block for a car luggage compartment door of the utility model, the adhesive layer is evenly applied to the inner side of the damping ring and adhered to the limit groove position at the edge of the first rubber disc and the second rubber disc, and the outer side of the damping ring contacts the inner wall of the silent buffer block body, so that when the damping ring is installed in the limit groove at the edge of the first rubber disc and the second rubber disc, the stability of the damping ring on the inner side of the limit groove is increased, and the damping ring is prevented from being separated from the limit groove when the damping ring contacts and rubs with the silent buffer block body.

[0014] The utility model has the following beneficial effects:

[0015] The silent buffer block body for a car luggage compartment door designed by the utility model cooperates with the design of the first rubber disc and the compression spring so that when the car luggage compartment door is closed, the compression spring between the first rubber disc and the second rubber disc in the silent buffer block body can not only absorb and disperse the impact force generated when the door is closed, thereby reducing damage to the vehicle body structure, but also the first rubber disc and the second rubber disc can quickly return to their original shape after being compressed under the drive of the compression spring, so that the silent buffer block body maintains an effective shape and function, thereby improving the service life of the silent buffer block body to a certain extent.
