[0021] In the description of the present utility model, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0023] See also Figure 1-4 The utility model provides a technical solution: an automobile steering column with a noise reduction structure, comprising a first steering column 1 and a second steering column 2, wherein a sliding ring 3 is slidably sleeved on the outer surface of the first steering column 1, a fixing ring 4 is fixedly sleeved on the outer surface of the second steering column 2, a sound absorbing ring 14 is fixedly connected between the sliding ring 3 and the fixing ring 4, and an adjusting component is arranged inside the first steering column 1.
[0024] Furthermore, the adjustment component includes a connecting column 7, the outer surface of the connecting column 7 is slidably connected to the inner wall of the first steering column 1, the top of the connecting column 7 is fixedly connected to the bottom end of the second steering column 2, the inner wall of the first steering column 1 is provided with an annular limit groove 9, the inner wall of the annular limit groove 9 is slidably connected to a limit plate 8, the top of the limit plate 8 is fixedly connected to the bottom end of the connecting column 7, the bottom end of the limit plate 8 is fixedly connected to a limit spring 10, and the limit spring 10 is arranged inside the annular limit groove 9.
[0025] Furthermore, two second thread grooves 12 are provided on the outer surface of the limit plate 8, and four first thread grooves 11 are provided on the outer surface of the first steering column 1. The positions and heights of the four first thread grooves 11 are different. The interiors of the two first thread grooves 11 close to the limit plate 8 are both threadedly connected with adjusting screws 13, and the opposite ends of the two adjusting screws 13 are respectively threadedly connected to the internal parts of the corresponding second thread grooves 12.
[0026] Furthermore, two slide grooves 5 are provided on the outer surface of the second steering column 2, and the inner walls of the two slide grooves 5 are slidably connected with slide plates 6, and the opposite ends of the two slide plates 6 are fixedly connected to the inner wall of the sliding ring 3 respectively. The opposite ends of the two slide plates 6 are provided with rotating grooves 15, and the inner walls of the two rotating grooves 15 are provided with rollers 16. The outer surfaces of the two rollers 16 will respectively roll in contact with the inner walls of the corresponding slide grooves 5.
[0027] Furthermore, the two adjusting screws 13 are first removed from the inside of the first thread groove 11, and then the limit plate 8 can restore the adjustment ability. Then, when the staff needs to adjust the required length of the automobile column, the second steering column 2 can be pressed, and then the second steering column 2 drives the connecting column 7 to move downward, and then the connecting column 7 drives the limit plate 8 to press the limit spring 10 downward. As the limit plate 8 moves downward, when the two second thread grooves 12 on the outer surface of the limit plate are respectively opposite to the first thread groove 11 at a lower height, the two adjusting screws 13 that have been removed can be respectively entered into the corresponding first thread groove 11, and then the two adjusting screws 13 will enter the second thread groove 12, so that the connecting column 7 is fixed in the second steering column 2, so that the first steering column 1 and the second steering column 2 can be adjusted. Through the coordinated stretching adjustment of the first steering column 1 and the second steering column 2, the disadvantage of the inconvenient height adjustment of the traditional integrated fixed type automobile column can be flexibly changed, so that it is convenient for the staff to use it better.
[0028] Furthermore, when the first steering column 1 and the second steering column 2 are adjusted, the two slide grooves 5 will slide along the two slide plates 6 respectively, so that the position of the sliding ring 3 can be made inconvenient, so that when the second steering column 2 is pressed down for adjustment, the position of the sliding ring 3 will not be affected, so that the sound-absorbing ring 14 can be always fixed between the connection between the first steering column 1 and the second steering column 2. When the steering column is vibrated and generates noise, the sound-absorbing ring 14 can effectively absorb the noise, thereby reducing the propagation and influence of the noise. The sound-absorbing ring 14 is a prior art and will not be described in detail here, so that noise reduction can be performed to a certain extent, so that the steering column of the vehicle can be better used. At the same time, through the setting of the roller 16, the second steering column 2 can slide more smoothly when adjusted.
[0029] Working principle: first remove the two adjusting screws 13 from the inside of the first thread groove 11, and then the limit plate 8 can restore the adjustment ability. Then when the staff needs to adjust the required length of the automobile column, the second steering column 2 can be pressed, and then the second steering column 2 drives the connecting column 7 to move downward, and then the connecting column 7 drives the limit plate 8 to press the limit spring 10 downward. As the limit plate 8 moves downward, when the two second thread grooves 12 on the outer surface of the limit plate are respectively opposite to the first thread groove 11 at a lower height, the two adjusting screws 13 that have been removed can be respectively entered into the corresponding first thread groove 11, and then the two adjusting screws 13 will enter the second thread groove 12, so that the connecting column 7 is fixed in the second steering column 2, so that the first steering column 1 and the second steering column 2 can be adjusted. Through the coordinated stretching adjustment of the first steering column 1 and the second steering column 2, the disadvantage of the inconvenient height adjustment of the traditional integrated fixed type automobile column can be flexibly changed, so that it is convenient for the staff to use it better.
[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
