Description

Technical Field

[0001] The utility model belongs to the technical field of automobile sunroof guide rails and relates to a guide rail stabilizing buffer device. Background Art

[0002] A car sunroof is a window installed on the roof of a car that allows air to circulate inside the car, increases the light inside the car, and brings a more comfortable and open riding experience to the driver and passengers. The types and sizes of car sunroofs vary depending on the car model. Some sunroofs can be opened and closed manually or electrically, while others are panoramic sunroofs that cover the entire roof. If the rail end of the car sunroof cannot effectively relieve the impact force when the sunroof is closed, a series of problems may occur.

[0003] When the sunroof rails cannot effectively relieve the impact, the most direct impact is that the sunroof will be hit by the impact and deformed and damaged, which may cause the sunroof to get stuck, bumpy, or even stop moving suddenly during opening or closing. This not only affects the normal use of the sunroof, but may also damage the sealing and waterproof properties of the sunroof.

[0004] In addition to the impact on the sunroof itself, the impact force of the sunroof that cannot be relieved may also affect the overall structure of the vehicle. Long-term exposure to such impact may cause fatigue of the metal structure on the top of the vehicle, thereby affecting the stability of the entire vehicle body. Therefore, a guide rail stabilization buffer device is urgently needed to solve the above problems. Utility Model Content

A base 190 for stably supporting the connecting seat 130 and the connecting shaft 180 is provided at the lower end of the connecting seat 130. The base 190 can be used to improve the stability of the housing 120 and the connecting shaft 180.

[0027] A limit piston 200 for increasing the impact friction force is provided on the right side inside the shell 120, a damping seat 210 for releasing the impact force is provided on the left side of the limit piston 200, and a release piston 220 for transmitting the remaining impact force is provided on the left side of the damping seat 210. The release piston 220 and the limit piston 200 can be used to limit the displacement length of the buffer tube 100 and preliminarily release the impact force.

[0028] A group of fixing holes are arranged inside the connecting head 110 , and the connecting head 110 is fixed to the external slow-release skylight seat by bolts. The connecting head 110 and the buffer tube 100 are an integrated structure.

[0029] The outer side of the left end of the buffer tube 100 is connected through the limit piston 200 and is fixedly connected to the right side of the damping seat 210. The damping seat 210 is an air damping column. The damping seat 210 is fixedly connected to the right side of the release piston 220.

[0030] A limit card is provided on the right side of the shell 120, a sealing ring is provided inside the left side of the shell 120, and a group of guide rods for transmitting impact force are provided on the left side of the slow-release piston 220.

[0032] See also Figure 1-Figure 4As the first embodiment of the utility model: in order to solve the problem that when the sunroof guide rail end cannot effectively release these impact forces, the most direct impact is that the sunroof will be hit by the impact force and deformed and damaged, which may cause the sunroof to get stuck, bumpy, or even suddenly stop moving during the opening or closing process. When the sunroof is closed, the sunroof moves to the edge of the sunroof guide rail and contacts the external slow-release sunroof connector. Then, after the external slow-release sunroof connector is subjected to the impact force, it drives the buffer tube 100 to move to the left, and at the same time drives the limit piston 200 and the slow-release piston 220 to move, and at the same time squeezes the guide rod, and makes the guide rod drive the connecting tail 150 to move to the left. Since the guide rod runs through the interior of the tension spring 140 and contacts the connecting tail 1 50 is connected and fixed, and its connecting tail 150 can stretch the tension spring 140 to the left side while driving the guide swivel seat 160 to rotate. Since the connecting tail 150 is connected and fixed to the guide swivel seat 160, the guide swivel seat 160 is a rotating mechanism. The middle position of the guide swivel seat 160 is penetrated by the rotating shaft 170 to fix the connecting shaft 180 and rotate the guide swivel seat 160 and the rotating shaft 170, and the impact force is transmitted to the end of the rotation damping 230 through the connecting shaft 180, thereby completing multiple slow releases and protecting the car sunroof. At the same time, because the tension spring 140 is stretched by using the guide rod, the reaction force of the impact is stored, and the external slow-release sunroof connector is kept in close contact with the sunroof for support.

[0033] See also Figure 1-Figure 4 , as the second embodiment of the utility model: based on the description in the above embodiment, further, since a limit piston 200 for increasing the impact friction force is provided on the right side inside the shell 120, the limit piston 200 and the release piston 220 can effectively limit the moving position of the buffer tube 100 inside the shell 120, thereby protecting the tension spring 140 and the rotation damping 230. At the same time, since the damping seat 210 is an air damping column, the damping seat 210 is fixedly connected to the right side of the release piston 220, and the initial release effect of the buffer tube 100 can be improved through the damping seat 210, and the impact force of the car sunroof can be released in the first time, and the corresponding reverse force can be provided to fit and support the car sunroof.
