Description

Technical Field

[0001] The utility model relates to the technical field of glass guide rails, in particular to a glass guide rail with a V-shaped guide structure. Background Art

[0002] The car sunroof is installed on the roof, which can effectively circulate air in the car and increase the entry of fresh air. At the same time, the car sunroof can also broaden the field of vision and meet the needs of mobile photography and video shooting. Its advantages are large sunroof opening and simple and beautiful appearance. Most cars use built-in sunroof, but if it is installed later, the price of this built-in sunroof is relatively high, and because the roof interior needs to be redone, the required construction technology is also very high. The external sunroof has the advantages of small size and simple structure.

[0003] In most cases, existing window rail designs do not have a buffer device. For example, the utility model with patent number CN217233183U, although it effectively solves the problems of jamming and abnormal noise when the glass is raised and lowered, does not have a buffer device. Such a design causes the glass to directly hit the edge of the glass when it falls, which not only increases the wear of the glass, but is also more likely to cause the glass to shatter, thus posing a threat to the safety of passengers. The raising and lowering of car window glass is a very common operation during our driving. However, if the window rail is not equipped with a buffer device, then every raising and lowering may become a potential danger. Utility Model Content

[0006] Preferably, an annular groove cooperating with the sleeve is provided on one side of the bottom cover close to the second sealing ring, and a similar groove is provided inside the housing away from the end of the bottom cover, and the two grooves cooperate with each other to fix the sleeve.

[0007] Preferably, a main body is provided on the outer side of the push rod at one end of the shell close to the tray, and a plurality of connecting parts are provided on one side of the main body for fixing the main body.

[0008] Preferably, a collar is provided at one end of the main body close to the shell for fixing the shell.

[0009] Preferably, the shell and the bottom cover, the bottom cover and the sealing bolt are all connected by threads, and the threaded connection modes of the shell and the bottom cover, and the bottom cover and the sealing bolt are opposite to each other, so as to prevent the bottom cover from rotating when the sealing bolt is rotated.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model achieves the purpose of shock absorption through a push rod, a tray, a sleeve, a shell and a stopper. Through the designed hydraulic damping system, the mechanism effectively adjusts the speed of the glass during the descent process. The push rod in the system and the hydraulic oil in the shell work together to achieve a buffering effect through the viscous resistance of the fluid. In order to ensure that the push rod moves accurately and smoothly, openings of specific sizes are designed on the side of the sleeve. These openings control the flow rate of the hydraulic oil. The openings are directly related to the dynamic stability of the push rod and reduce the impact force generated by the glass when it is closed, thereby significantly reducing the possibility of glass shattering and improving the safety performance of the overall system.

[0022] Furthermore, a main body 1 is provided on the outer side of the push rod 6 at one end of the shell 5 close to the tray 4 , and a plurality of connecting members 2 are provided on one side of the main body 1 for fixing the main body 1 .

[0023] Furthermore, a collar is provided at one end of the main body 1 close to the outer shell 5 for fixing the outer shell 5 .

[0024] Furthermore, the shell 5 and the bottom cover 13, as well as the bottom cover 13 and the sealing bolt 8 are all connected by threads, and the threaded connection modes of the shell 5 and the bottom cover 13, as well as the bottom cover 13 and the sealing bolt 8 are opposite, to prevent the bottom cover 13 from rotating when the sealing bolt 8 is rotated.

[0025] Working principle: A glass guide rail with a V-shaped guide structure, which consists of a main body 1 and a shell 5. One end of the shell 5 is provided with an opening, and a second annular sealing ring 15 is set on the edge of the opening to ensure the sealing and anti-leakage function. The bottom cover 13 is adjacent to the second sealing ring 15. The bottom cover 13 is connected to the shell 5 by threads, and a sealing bolt 8 is sleeved inside the bottom cover 13; a first sealing ring 7 is arranged between the bottom cover 13 and the sealing bolt 8 to enhance the sealing effect. A sleeve 9 of a matching design is installed on the side of the bottom cover 13 adjacent to the second sealing ring 15. The side of the sleeve 9 is provided with a plurality of openings 10. The function of these openings 10 is to limit the flow rate of the hydraulic oil. When the push rod 6 is subjected to the thrust from the glass falling, the push rod 6 pushes the block 11 to fall. The hydraulic oil filled on both sides of the sleeve 9 inside the shell 5 is limited in flow rate by the openings 10 opened on the side of the sleeve 9, thereby slowing down the movement speed of the push rod 6 to provide a smooth power transmission. The sleeve 9 contains a spring 12, one end of which is connected to the stopper 11; the stopper 11 is connected to the push rod 6, and the other end of the push rod 6 fixes the tray 4. The tray 4 is embedded with a rubber pad 3 to reduce the impact force when the glass touches the tray 4. The spring 12 pushes the push rod 6 outward by cooperating with the stopper 11, so as to prepare for the next shock absorption operation. In order to ensure the stability of the structure, the bottom cover 13 is provided with an annular groove 14 that matches the sleeve 9 on the side close to the second sealing ring 15, and at the same time, a similar groove 14 is also provided at the far end of the inner shell 5. The two grooves 14 cooperate with each other to enable the sleeve 9 to be firmly fixed in the set position. The main body 1 is also provided with a ring at one end close to the shell 5, which is used to fix the shell 5. During the assembly process, the connection between the shell 5 and the bottom cover 13, and the connection between the bottom cover 13 and the sealing bolt 8 are all realized by threads. It is worth noting that the threads between the shell 5 and the bottom cover 13 are reverse thread designs. This design can prevent the bottom cover 13 from rotating when the sealing bolt 8 is rotated, thereby ensuring the accuracy of operation and the integrity of the structure.
