Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile steering, in particular to a CEPS bracket component that can provide continuous collapse force. Background Art
[0002] National regulations GB11557 stipulate that when a car is involved in a frontal collision in a traffic accident, the column assembly must have a crumple energy absorption function to prevent the human body from instantly moving forward and hitting the steering wheel, causing great damage. In the early stage, customers required the column to provide a peak crumple force. Current research shows that after the crumple occurs, that is, after the peak crumple force, the continuous crumple force provided by the column has a positive effect on collision safety when it is 1500N~2500N.
[0003] Most of the existing technologies provide continuous collapse force through injection-molded pads and tear-off sheet structures. The collapse structure requires the angle adjustment bracket and the column mounting bracket to be fixedly connected by welding. The injection-molded block is fixedly connected to the mounting bracket through an injection molding process, which has poor processability. At the same time, the continuous collapse force provided by the tear-off sheet has large dispersion and poor consistency. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a CEPS bracket component that can provide continuous collapse force, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model discloses a CEPS bracket assembly that can provide continuous collapse force, and the technical solution adopted is that it includes a mounting bracket and an adjustment bracket. The mounting bracket is symmetrically provided with fixing holes, the middle part of the mounting bracket is mirrored to open a first collapse groove, and a second collapse groove is opened between the first collapse grooves. The first collapse groove and the second collapse groove mainly provide a guiding function during collapse. The first collapse groove is provided with a first collapse boss, and the second collapse groove is provided with a second collapse boss. The second collapse boss is shorter in length. The first collapse boss and the second collapse boss are used to provide collapse peak force and collapse preload force. The mounting bracket is provided with an adjustment bracket, and a through hole is opened on the adjustment bracket. The mounting bracket and the adjustment bracket are fixed together by rivets. When a collision occurs, the mounting bracket and the adjustment bracket pass through, and the rivet, the first collapse groove and the second collapse groove are relatively displaced to achieve collapse energy absorption.
[0006] As a preferred technical solution of the utility model, the mounting bracket is fixed to the vehicle mounting plate through the fixing hole, and a steering column is provided on the adjustment bracket.
[0007] As a preferred technical solution of the utility model, the first collapse groove is a waist-shaped through hole, the second collapse groove is a notch, the first collapse groove includes a first end and a second end, the first end of the first collapse groove is provided with a closing opening, the closing opening is smaller than the diameter of the second end, so that the first rivet contacts the inner wall of the first collapse groove, and there is friction resistance between the two. When collapse occurs, the first rivet and the inner wall of the first collapse groove provide friction resistance. After collapse occurs, the first rivet passes through the closing opening, and the first rivet and the inner wall of the first collapse groove are no longer in contact, and there is no friction resistance.
[0008] As a preferred technical solution of the utility model, the rivet includes the first rivet and the second rivet, the first rivet is located inside the first collapse groove, and the second rivet is located inside the second collapse groove.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model installs the bracket and the adjustment bracket in plane fit and fixes them together by rivets. This structure omits welding, injection molding and other processes, and the process is simple. By changing the length of the first collapse boss, the continuous distance of the collapse can be changed, and by changing the height of the first collapse boss, the peak force and continuous force of the collapse can be changed.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0022] like Figures 1 to 9 As shown, the utility model discloses a CEPS bracket assembly that can provide continuous collapse force. The technical solution adopted is that it includes a mounting bracket 1 and an adjusting bracket 2. The mounting bracket 1 has fixing holes 7 on both sides. The mounting bracket 1 is connected to the mounting plate of the whole vehicle through bolts and the fixing holes 7. A second collapse groove 401 is opened in the middle of the mounting bracket 1. First collapse grooves 4 are opened in mirror image on both sides of the second collapse groove 401. The first collapse groove 4 is a waist-shaped through hole, and the second collapse groove 401 is a notch. A first collapse boss 5 is provided on the first collapse groove 4, and a second collapse boss 501 is provided on the second collapse groove 401. The second collapse boss 401 is shorter in length.
[0023] As a preferred technical solution of the utility model, a through hole 6 is provided on the adjusting bracket 2, and the adjusting bracket 2 is fixed to the mounting bracket 1 through the through hole 6 and the rivet 3. A steering column is provided on the adjusting bracket 2, and the rivet 3 includes a first rivet 301 and a second rivet 302. The first rivet 301 fixes the mounting bracket 1 and the adjusting bracket 2 together through the first shrinkage groove 4, and the second rivet 302 fixes the mounting bracket 1 and the adjusting bracket 2 together through the second shrinkage groove 401.
[0024] As a preferred technical solution of the utility model, the first collapse groove 4 includes a first end 8 and a second end 801, the first end 8 is far away from the second collapse groove 401, the second end 801 is close to the second collapse groove 401, and the first end 8 of the first collapse groove 4 is provided with a closing opening, such as Fig. 9As shown, the closing portion is smaller than the diameter of the second end 801 .
[0025] The working principle of the utility model is as follows: under normal circumstances, the mounting bracket 1 and the adjusting bracket 2 are fixed by the clamping force provided by the rivet 3, the first collapse boss 5 and the second collapse boss 501. When the vehicle collides and collapses, the mounting bracket 1 and the adjusting bracket 2 generate relative friction due to the clamping force of the rivet 3. At the same time, after the rivet 3 is riveted, the outer ring of the rivet 3 contacts the inner wall of the collapse groove, providing additional friction resistance between the two, and the two generate a collapse peak force. When the movement is too large and causes the second rivet 302 to collapse out of the second collapse groove 401, the second rivet 302 will no longer provide friction resistance. At this time, the first rivet 301 still provides preload and friction in the first collapse groove 4, providing continuous force during the collapse process.
[0026] When the continuous distance of the collapse needs to be changed according to different requirements, the protruding length of the first collapse boss 5 can be changed; when the peak force and continuous force of the collapse need to be changed according to different requirements, the protruding height of the first collapse boss 5 can be changed.
[0027] The mechanical connection involved in the utility model is a common means used by technical personnel in this field, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.
[0028] Components not described in detail herein are prior art.
