Description

Technical Field

[0001] This utility model relates to the field of steering column technology, specifically a roll-type collapsible structure for a four-way adjustable electrically adjustable steering column. Background Technology

[0002] With the development of new energy vehicles, the requirements for vehicle size, handling comfort, and collision safety are becoming increasingly stringent. Currently, the steering column is gradually being replaced by an electrically adjustable column, replacing the manually adjustable column. This requires higher adjustment performance, stiffness, and crumple zone capacity, and must be able to adjust according to the vehicle's collision requirements. However, existing electrically adjustable columns have relatively poor stiffness, and their crumple zone structures suffer from a small adjustment range, require a large space, are difficult to adjust, and cannot cope with complex crumple zone requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a roll-type collapsible structure for a four-way adjustable electrically adjustable tube column, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model discloses a roll-type collapsible structure for a four-way adjustable electrically adjustable tubing column, the technical solution of which includes a lower tubing column. The lower tube column has an axial adjustment motor on its side. The output end of the axial adjustment motor is connected to an adjustment bracket, which extends into the lower tube column. One end of the adjustment bracket has a U-shaped groove, and the bottom of the other end has a bracket protrusion. The lower tube column is slidably connected to the upper tube column. The upper tube column has a guide bracket groove above it. The upper tube column on the left side of the guide bracket groove has a mounting base. The bracket protrusion is slidably connected to the inside of the guide bracket groove. The adjustment bracket is fixed to the guide bracket groove by a force-bearing shaft, such as a rivet or pin. The adjustment bracket has a winding tape with multiple layers. One end of the winding tape is fixed to the mounting base by a second bolt, and the other end is connected to the adjustment bracket. A guide block is detachably connected above the winding tape. The lower tube column outside the guide block has a guide groove with a guide strip inside. The guide block is slidably connected to the inside of the guide strip. The guide strip has a cover plate, which is fixed to the guide groove.

[0005] As a preferred embodiment of this utility model, a fixed bracket is provided on the side of the lower tube column, and the axial adjustment motor is connected to the lower tube column through the fixed bracket.

[0006] As a preferred technical solution of this utility model, the U-shaped groove of the adjusting bracket has a first bolt inside, and the adjusting bracket is fixed to the guide bracket groove by the first bolt. When the upper tube cylinder collapses into the lower tube cylinder, the force-bearing shaft breaks and provides an instantaneous peak force, and then the first bolt is released from the U-shaped groove.

[0007] As a preferred technical solution of this utility model, the guide block and the winding belt are fixed together to the adjusting bracket by a third bolt. When the upper tube column collapses and moves to the left, the winding belt will generate a resistance in the opposite direction.

[0008] As a preferred technical solution of this utility model, an avoidance opening is provided on the tape, and the avoidance opening is concentric with the first bolt and the second bolt, which facilitates the disassembly of the first bolt and the second bolt, and facilitates the disassembly or replacement of the tape.

[0009] As a preferred technical solution of this utility model, the guide strip is provided with a limiting post, the cover plate is provided with a limiting hole, the limiting hole and the limiting post cooperate, the cover plate is fixed to the guide bracket groove by a fourth bolt, and the fixed bracket is fixed by the cover plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: this utility model fixes one end of the winding tape to the mounting base and the other end to the adjusting bracket, so that the lower tube and the upper tube have better rigidity. The winding tape has multiple layers and is easy to disassemble and replace. Different thicknesses or materials of the winding tape and the quantity can be combined according to the actual situation to meet the requirements of complex collapse force.

Example 1

[0020] like Figures 1 to 7As shown, this utility model discloses a tape-type collapsible structure for a four-way adjustable electrically adjustable tube column. The technical solution includes a lower tube column 1, with a fixed bracket 101 on its side. An axial adjustment motor 3 is connected to the lower tube column 1 via the fixed bracket 101. The output end of the axial adjustment motor 3 is connected to an adjustment bracket 4, which extends into the lower tube column 1. One end of the adjustment bracket 4 has a U-shaped groove 401, and the bottom of the other end has a bracket protrusion 403. An upper tube column 2 is slidably connected inside the lower tube column 1. A guide bracket groove 201 is provided above the upper tube column 2. A mounting base 8 is provided on the upper tube column 2 to the left of the guide bracket groove 201. The bracket protrusion 403 is slidably connected to the inside of the guide bracket groove 201. The adjustment bracket 4 is fixed to the guide bracket groove 201 via a force-bearing shaft 7. A first bolt 402 is located inside the U-shaped groove 401 of the adjustment bracket 4, and the adjustment bracket 4 is fixed to the guide bracket groove 201 by the first bolt 402. A tape 6 is attached to the adjustment bracket 4. The tape 6 has multiple layers, and different thicknesses or materials of tape 6 can be combined to meet different collapse force requirements. One end of the tape 6 is fixed to the mounting base 8 by the second bolt 801, and the other end is connected to the adjusting bracket 4. An clearance opening 601 is provided on the tape 6, which is concentric with the first bolt 402 and the second bolt 801, facilitating the installation and removal of the first bolt 402 and the second bolt 801. A guide block 9 is detachably connected to the top of the tape 6, and the guide block 9 and the tape 6 are connected by a third bolt 9. 01 is fixed together to the adjusting bracket 4. The lower tube column 1 outside the guide block 9 is provided with a guide groove 5. The guide groove 5 contains a guide strip 10. The guide block 9 is slidably connected to the inside of the guide strip 10. The guide strip 10 has a cover plate 11. The cover plate 11 is fixed to the guide groove 5. The guide strip 10 is provided with a limiting post 1001. The cover plate 11 has a limiting hole 1101. The limiting hole 1101 and the limiting post 1001 cooperate. The cover plate 11 is fixed to the guide bracket groove 201 by the fourth bolt 12.

[0021] The working principle of this utility model is as follows: When the upper tube column 2 collapses inside the lower tube column 1, the upper tube column 2 drives the mounting base 8 to move to the left. The winding belt 6 fixed to the mounting base 8 moves to the left simultaneously. The other end of the winding belt 6 is fixed to the adjusting bracket 4 and remains stationary. At this time, the adjusting bracket 4 and the guide bracket groove 201 slide relative to each other. When the limit is reached, the force shaft 7 breaks to provide peak force. The U-shaped groove 401 disengages from the first bolt 402. At this time, the upper tube column 2 continues to move to the left. The bracket protrusion 403 slides and guides in the guide bracket groove 201 and plays a role in collapse. At this time, the upper tube column 2 drives one end of the winding belt 6 to continue to move to the left and absorbs energy through the winding of the winding belt 6, thereby completing the collapse.
