Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a support connection structure of a steering column and a shield. Background Art

[0002] The assembly of the steering column and the guard occurs during the vehicle assembly stage, and the connection point between the steering column and the guard is usually defined by the OEM. To ensure the universality of the steering column, an independent guard connection bracket is usually designed based on the connection point position given by the OEM, and assembled on the column by bolts or other detachable means, resulting in assembly errors.

[0003] Considering the cost and layout space, the shield connection bracket is mostly stamped and has been bent many times, so springback is difficult to avoid. In addition, the assembly error makes it difficult for the actual connection point on the shield connection bracket to meet the position requirements of the OEM. After forced assembly, there is residual stress, which has an adverse effect on the strength of the connection and the positioning of the shield itself.

[0004] Therefore, it is necessary to design a bracket connection structure between the steering column and the shield, which can compensate for the position deviation caused by the rebound of the stamping parts and the assembly error, so that the connection point meets the position requirements of the OEM. At the same time, the shield can be fixed on the steering column so that the shield moves with the steering column without shaking. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a bracket connection structure for a steering column and a shield, which can compensate for the position offset caused by the springback of stamped parts and assembly errors, so that the connection point meets the position requirements of the main engine manufacturer. At the same time, the shield can be fixed on the steering column so that the shield moves with the steering column without shaking.

[0006] In order to achieve the above-mentioned purpose, the utility model is a bracket connection structure for a steering column and a shield, comprising a shield, a steering column, a bracket, a connecting pin and a screw. The steering column and the shield are connected by the bracket, and the shield and the bracket are connected by connecting pins and screws. The connecting pin is inserted into the mounting hole of the bracket, and the screw passes through the connecting pin and is fastened to the shield.

[0007] The connecting pin includes a column and an anti-slip structure. The column is provided with an anti-slip structure pre-assembled with the bracket. The anti-slip structure protrudes from the surface of the column. The upper surface of the column is provided with a deformation groove extending downward along the column. The interior of the column is a through cavity. The inner wall of the through cavity is provided with a guide groove matching the screw. The outer diameter of the column is smaller than the aperture of the mounting hole, and the inner diameter of the column is smaller than the outer diameter of the screw thread.

[0008] The anti-drop structure comprises a protruding structure and a flange. The protruding structure is arranged at two ends of the bottom of the column, and the flange is arranged at the top of the column.

[0009] The cross section of the protruding structure is an inverted triangle.

[0010] The inner surface of the mounting hole is symmetrically provided with a plurality of sawtooth structures.

[0011] A gap is provided between the sawtooth structure and the undeformed connecting pin, and the deformed connecting pin is embedded in the sawtooth structure.

[0012] The teeth of the sawtooth structure face the outside of the mounting hole.

[0013] The mounting holes are arranged on the mounting surface of the bracket.

[0014] The screws are self-tapping screws.

[0015] Compared with the prior art, the utility model designs a bracket connection structure between the steering column and the shield, and the connecting pin can rotate in the mounting hole of the bracket and achieve a certain degree of movement, thereby compensating for the position offset caused by stamping rebound and assembly error, so as to adjust the installation position and meet the position requirements of the main engine manufacturer for the connection point. During the assembly process, the screw presses against the inner wall of the connecting pin, and the connecting pin column deforms along the deformation groove and clamps in the mounting hole of the bracket, thereby normally performing the function of fixing the shield.

[0023] The utility model is now further described with reference to the accompanying drawings.

[0024] See also Figure 1, Figure 5 The utility model is a bracket connection structure of a steering column and a shield, comprising a shield, a steering column, a bracket, a connecting pin, and a screw. The steering column 4 and the shield 1 are connected by a bracket 2, and the shield 1 and the bracket 2 are connected by a connecting pin 3 and a screw 5. The connecting pin 3 is inserted into the mounting hole 23 of the bracket 2, and the screw 5 passes through the connecting pin 3 and is fastened to the shield 1.

[0025] Among them, the bracket 2 is a metal part, and the shape of the bracket 2 can be designed according to the requirements of the main engine manufacturer and the surrounding environment of the vehicle; the connecting pin 3 is a plastic part. Different connecting pins 3 can be combined with different brackets 2 to improve the utilization rate of parts. The screw 5 is a self-tapping screw.

[0026] See also Figure 3 , Figure 4 The connecting pin 3 includes a column 32 and an anti-slip structure. The column 32 is provided with an anti-slip structure pre-assembled with the bracket 2. The anti-slip structure protrudes from the surface of the column 32. The upper surface of the column 32 is provided with a deformation groove 35 extending downward along the column 32. The deformation groove 35 makes the column 32 easier to deform and can guide the deformation amount in the same direction, which is conducive to the connection pin 3 after deformation to fix itself in the current position. The interior of the column 32 is a through cavity, which is convenient for discharging the material cut off when the screw 5 is screwed in. A guide groove 34 matching the screw 5 is provided on the inner wall of the through cavity to ensure that the screw 5 is coaxial with the connecting pin 3. The outer diameter of the column 32 is smaller than the aperture of the mounting hole 23, so that the connecting pin 3 has a certain amount of movement in the mounting hole 23 and can rotate freely when it is not connected to the shield 1. The inner diameter of the column 32 is smaller than the outer diameter of the thread of the screw 5.

[0027] The anti-slip structure includes a protruding structure 31 and a flange 33 . The protruding structure 31 is arranged at two ends of the bottom of the column 32 , and the flange 33 is arranged at the top of the column 32 .

[0028] The cross-section of the protrusion structure 31 is an inverted triangle. During pre-assembly, the inverted triangle-shaped protrusion structure 31 is easy to press into the mounting hole 23 of the bracket 2, and after being pressed in, the inverted triangle-shaped protrusion structure 31 can prevent the connecting pin 3 from falling out of the mounting hole 23.

[0029] See also Figure 2 The mounting hole 23 is provided on the mounting surface 21 of the bracket 2, and the mounting hole 23 is used to install the connecting pin 3. The inner surface of the mounting hole 23 is symmetrically provided with a plurality of serrated structures 22, preferably four serrated structures 22, and the serrations of the serrated structures 22 face the outside of the mounting hole 23.

[0030] There is a gap between the sawtooth structure 22 and the undeformed connecting pin 3, and the sawtooth structure 22 does not affect the movement of the connecting pin 3 in the mounting hole 23. When the connecting pin 3 is connected to the shield 1 and the screw 5 is screwed in, the connecting pin 3 expands outward along the deformation groove 35 to achieve deformation, and the deformed connecting pin 3 is embedded in the sawtooth structure 22, thereby preventing the connecting pin 3 from rotating or moving, and improving the fixing effect.

[0031] During pre-assembly of the present invention, the connecting pin 3 is installed in the mounting hole 23 of the bracket 2. Due to the presence of the protruding structure 31 and the flange 33, the connecting pin 3 can move or rotate in the mounting hole 23 of the bracket 2, but will not fall off during transportation.

[0032] When the shield is assembled and positioned, the connecting pin 3 is moved and rotated in the mounting hole 23 of the bracket 2 to align with the connecting point of the shield 1 , and the screw 5 passes through the connecting point of the shield 1 and contacts the guide groove 34 of the connecting pin 3 .

[0033] The screw 5 is screwed into the connecting pin 3 . When the screw 5 is tightened, the connecting pin 3 will deform along the deformation groove 35 of the column 32 toward both sides of the column until the connecting pin 3 is clamped in the mounting hole 23 of the bracket 2 .

[0034] In order to achieve the adjustable installation position, the connecting pin 3 can move and rotate freely in the installation hole 23 of the bracket 2. Figure 5 As shown, when the screw 5 is just installed into the connecting pin 3, the connecting pin 3 is slightly deformed and has not yet been completely clamped in the mounting hole 23 of the bracket 2, so the connecting pin 3 can rotate with the screw 5. As the screw 5 is pressed in, the deformation of the connecting pin 3 increases. Figure 6 As shown, the deformation direction of the connecting pin 3 is perpendicular to the position offset direction of the connecting pin 3 in the mounting hole 23. The connecting pin 3 only needs to deform a small amount along the Y direction to be close to the wall of the mounting hole 23. In addition, with the serrated structure 22, the connecting pin 3 only needs to rotate a small angle with the screw 5 to be clamped in the mounting hole 23. At this time, the deformation direction of the connecting pin 3 is still roughly perpendicular to the position offset direction of the connecting pin 3.

[0035] like Figure 7 As shown, the deformation direction of the connecting pin 3 is the same as the position offset direction of the connecting pin 3 in the mounting hole 23, both of which are in the X direction. Since the deformation of the connecting pin 3 is not enough to contact the wall of the mounting hole 23 in the negative direction of the X direction at the beginning, the connecting pin 3 will rotate with the screw 5 until the deformed connecting pin 3 contacts the wall of the mounting hole 23 and is clamped. At this time, the direction of the deformation groove 35 of the connecting pin 3 will be changed from Figure 7 Status towards Figure 6 State transition.

[0036] Through the above analysis, no matter whether the initial deformation direction of the connecting pin 3 is perpendicular to the position deviation direction of the connecting pin 3, after the screw 5 is installed, it will automatically clamp near this position without manual intervention. The utility model can adjust its own point position to a certain extent according to the installation point position and position requirements given by the customer, and the assembly process is simple, without adding additional processes and beats, and has practical value.

[0037] The utility model designs a bracket connection structure for the steering column and the shield, and the connecting pin can rotate in the mounting hole of the bracket and move to a certain extent, thereby compensating for the position offset caused by stamping rebound and assembly error, so as to adjust the installation position and meet the position requirements of the main engine manufacturer for the connection point. During the assembly process, the screw presses against the inner wall of the connecting pin, and the connecting pin column deforms along the deformation groove and clamps in the mounting hole of the bracket, thereby normally performing the function of fixing the shield.
