The following provides a detailed description of examples of the present specification.
As shown in fig. 1 to 2, the steering column collapse mechanism of the present invention includes an upper column tube 10, a lower column tube 20, and a collapse assembly 30. The collapsing assembly 30 is respectively fixed and matched with the upper column tube 10 and the lower column tube 20, and the lower end of the upper column tube 10 is arranged in the lower column tube 20.
As shown in fig. 3 to 4, tear-off steel strip 31 is provided with a fixed steel strip 310, a bent steel strip 311, and a tear-off groove 312 between fixed steel strip 310 and bent steel strip 311. The fixed steel belt 310 is fixed to the upper column tube 10, and the winding steel belt 311 is fixed to the lower column tube 20 via the slide block 33 and the connecting member 35.
The bent steel strip 311 includes a bent portion 3111, and a fixing portion 3112 and a first tear portion 3110 provided at both ends of the bent portion 3111. The bent portion 3111 is provided around and attached to the guide block 34, and the bent portion 3111 and the first tear portion 3110 are deformed by the guide block 34. The fixing portion 3112 is fixed to the slide block 33 and the link 35. The fixing steel band 310 includes a second tear portion 3101 connected to the first tear portion 3110 and a protrusion 3102 extending from the second tear portion 3101 toward the lower column tube 20.
The width of the fixing portion 3112 is equal to the total width of the first tear portion 3110, the tear groove 312, and the second tear portion 3101. Fixed part 3112 is last to be equipped with cooperation groove 3113, cooperation groove 3113 and sliding block 33 interference fit. The width of the protrusion 3102 is greater than the width of the second tear portion 3101, mounting holes 3103 are provided on both the second tear portion 3101 and the protrusion 3102, and the mounting holes 3103 on the protrusion 3102 have a relatively large diameter.
An elongated tear groove 312 is formed between the first tear portion 3110 and the second tear portion 3101, and the thickness of the tear groove 312 is smaller than the thicknesses of the first tear portion 3110 and the second tear portion 3101. When the tear groove 312 is collapsed, the first tear portion 3110 and the second tear portion 3101 are gradually broken along the tear groove 312 and separated from each other because the structure is relatively weak at the tear groove 312.
Specifically, the tear groove 312 is provided along the collapsing direction of the collapsing assembly 30, one end of the tear groove 312 is flush with the first and second tear portions 3110 and 3101, and the other end extends to the bent portion 3111, so that the first and second tear portions 3110 and 3101 can be completely separated.
One end of the guide block 34 is a flat end and the other end is a circular end. The flat end is clamped in the guide 32, and the circular end is located outside the guide 32 and attached to the bent portion 3111. During the collapse initiation and stabilization phase, the guide block 34 moves toward the lower column tube 20. Since the fixing portion 3112 of the bent steel strip 311 is fixed to the lower column tube 20, the guide block 34 abuts against the bent steel strip 311, and the first tear portion 3110 of the bent steel strip 311 is gradually bent and deformed by the guide block 34.
As shown in fig. 5 to 7, the guide 32 includes a bottom plate 322 and a pair of side plates 323 extending perpendicularly from both side edges of the bottom plate 322. The side plate 323 is welded and fixed to the upper column tube 10, the bottom plate 322 is provided with a guide groove 320, and the pair of stoppers 321 protrude from the side wall of the guide groove 320 into the guide groove 320. The bottom plate 322 and the pair of side plates 323 form a receiving groove 324, and the first tear portion 3110, the tear groove 312, and the second tear portion 3101 of the tear strip 31 are located in the receiving groove 324.
The slide block 33 is located in the guide groove 320 and is clearance-fitted thereto. When the steel band is collapsed, the slide block 33 and the guide groove 320 move relative to each other, and the fixed portion of the bent steel band 311 is fixed to the slide block 3, so that the first tear portion 3110 of the bent steel band 311 can be stably deformed in the fixed direction.
As shown in fig. 1 and 3, the connecting member 35 includes a base plate 350 and a fixing plate 351 vertically extending from an edge of the base plate 350. The base plate 350 is fixed to the lower column tube 20, and the slider 33 and the bent steel band 311 of the tear steel band 31 are fixed to the lower column tube 20. The fixing plate 351 is provided with a fixing groove 352, and the fixing groove 352 is in interference fit with the sliding block 33. The lower column tube 20 is provided with a downward moving groove 21, and the collapsing assembly 30 is arranged in the downward moving groove 21.
In the collapse start stage, the upper column tube 10, the guide 32, the guide block 34, and the fixed steel band 310 move toward the lower column tube 20, and the lower column tube 20, the connecting member 35, the sliding block 33, and the winding steel band 311 remain stationary. The slider 33 first hits the stopper 321 of the guide 32, providing a peak force of the collapsing force. As the upper column tube 10, the guide 32, the guide block 34, and the fixed steel strip 310 are further collapsed, the tear groove 312 between the fixed steel strip 310 and the bent steel strip 311 is torn at the collapse stabilization stage, and the bent steel strip 311 starts to be deformed by the guide block 34. Tearing of tear groove 312 occurs simultaneously with deformation of curved steel strip 311, providing stable crush retention.
According to the steering column collapse mechanism provided by the application, in the initial collapse stage, the limiting block 321 is broken to provide initial collapse force; in the collapse stabilization stage, the tearing groove 312 tears and the winding steel strip 311 deforms to provide collapse force, and the energy absorption capacity of the steering column collapse mechanism is improved. And the tearing of the tearing groove 312 and the deformation of the winding steel strip 311 occur simultaneously, and the two different types of crumple structures are arranged at the crumple stabilizing stage, so that the tearing force of the tearing steel strip 31 and the deformation force of the winding steel strip 311 jointly provide a stable crumple force, the safety of the vehicle is improved, and the injury of a driver in the vehicle collision is effectively reduced.
Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
