The present invention relates to a tilt and telescope steering device. More particularly, the present invention relates to a steering apparatus having a tilt slip elastic body in a moving tube sliding in a teles operating direction in a steering apparatus having a tilt function and a teles function.

Various devices are installed in the car to improve the safety of the car and the driver's convenience. Among them, the steering device is a device that allows the driver to turn the steering wheel to change the direction of the car freely. It is a device that assists the driver to move the car in the desired direction by arbitrarily changing the center of rotation.

In recent years, as the competition in the automobile market is intensifying and competition with automobile companies in each country is intensifying, advanced driver-oriented intelligent cars are being advanced. One of these trends is that the driver can easily hold the steering wheel and drive comfortably. Tilt-and-telescope steering with a drive motor that adjusts the relative position of the steering wheel relative to the driver is being expanded.

Here, the tilt and telescope steering system means adjusting the position of a steering wheel used in a car, and the adjustment of the position of the steering device includes a tilt operation and a telescope operation.

First, the tilt operation adjusts the fixed angle of the steering wheel (ie, the relative angle between the steering column and the steering wheel) according to the driver's position seated in the driver's seat, and the telescope operation lengthens the steering column length according to the driver's body shape. Adjust the distance between the steering wheel and the driver by increasing or shortening.

1 is a schematic diagram of a conventional tilt and telescope steering device. 1 shows a steering wheel 100, an upper steering shaft 102, a moving tube 104, a first vehicle body fixing portion 106, a fixing tube 108, a joint 112, a lower steering shaft 114, and The first tilt elastic body 116, the elastic body fixing part 118, the second vehicle body fixing part 120, the adjusting part 122, and the lever 124 are illustrated.

An upper steering shaft 102 is connected to the steering wheel 100 operated by the driver, and a joint 112 connected to the lower steering shaft 114 is provided at an end of the upper steering shaft 102. The steering shaft is enclosed by the moving tube 104 and the fixed tube 108, and the fixed tube 108 has a structure inserted into the moving tube 104. The adjusting unit 122 is provided at one side of the moving tube 104, and the adjusting unit 122 is fixed to the vehicle body by the first vehicle body fixing unit 106.

In addition, one side of the fixed tube 108 is provided with a first tilt elastic body 116. One side of the first tilt elastic body 116 supports the fixing tube 108 and the other side is fixed to the second vehicle body fixing part 120 by the elastic body fixing part 118. In other words, the elastic fixing part 118 is configured to fix the first tilt elastic body 116.

When the driver releases the lever 124, the moving tube 104 moves in the tilt operating direction Y or the teles operating direction X, wherein the first tilt elastic body 116 is the steering wheel 100, the upper steering. By elastically supporting the shaft 102, the moving tube 104 and the fixed tube 108, the tilting operation of the steering wheel 100 can be easily performed. As a result, the first tilt elastic body 116 allows the driver to move the steering wheel 100 in the tilt operating direction Y using a small force.

On the other hand, in the steering apparatus having a conventional tilt or teles function, the first tilt elastic body 116 is installed in the fixed tube 108, that is, the portion where the teles operation is not performed. Therefore, there is a problem in that there is a limitation in installing the first tilt elastic body 116.
