Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive steering technology, specifically a novel soft-limiting structure for steering column handles. Background Technology
[0002] To enhance the driver's experience, steering columns typically feature an adjustment function. When the adjustment lever is released, the steering column's mating parts are in a clearance fit, allowing for adjustment. When the adjustment lever is locked, the mating parts are in an interference fit, maintaining a holding force. The greater the difference in height between the locking components, the greater the clearance between the parts when the lever is released, resulting in less adjustment force and a smoother feel. However, since the release and locking of the lever are achieved through the interchangeable engagement of the locking components' heights, a greater difference in height leads to louder collision noises during the transition and more pronounced lever vibration after release, which can easily cause driver complaints. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of soft limit structure for steering column handle, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model discloses a novel soft-limiting structure for a steering column handle. The technical solution includes an outer column assembly and an angle adjustment bracket. The angle adjustment bracket is located outside the outer column assembly and is connected to the outer column assembly via a locking bolt. An axial soft-limiting block is slidably connected inside the angle adjustment bracket. The locking bolt passes through the axial soft-limiting block and has a first locking element. A locking spring is located between the first locking element and the axial soft-limiting block. A second locking element is located on the other side of the first locking element. A buffer ring is located between the first and second locking elements. A handle is located on the right side of the second locking element, and nuts are located on both sides of the locking bolt.
[0005] As a preferred technical solution of this utility model, angle adjustment grooves are opened on both sides of the angle adjustment bracket.
[0006] As a preferred technical solution of this utility model, the outer tube column assembly has grooves on both sides, and the angle adjustment groove is located on both sides of the grooves. The locking bolts pass through the grooves and the angle adjustment grooves to make them a whole.
[0007] As a preferred technical solution of this utility model, the axial soft limiting block slides into the sink groove, a countersunk hole is opened in the middle of the axial soft limiting block, and noise reduction blocks are on both sides of the axial soft limiting block.
[0008] As a preferred technical solution of this utility model, the locking spring slides onto the locking bolt, with one end of the locking spring located inside the groove and the other end in contact with the first locking member.
[0009] As a preferred technical solution of this utility model, a fixing groove is opened in the middle of the first locking member, and the buffer ring is fixed inside the fixing groove.
[0010] As a preferred technical solution of this utility model, a self-locking nut is screwed onto the handle end of the locking long bolt, and a locking nut is screwed onto the other end.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model reduces collision noise by adding a buffer ring between the first locking member and the second locking member; when loose, the locking spring pushes against the first locking member and the second locking member on the handle side, thereby reducing the gap on both sides of the handle and preventing the handle from shaking; when the axial soft limit block slides inside the groove, it contacts the noise reduction block when it moves to the limit position, thereby preventing collision noise.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0019] like Figures 1 to 5As shown, this utility model discloses a novel soft-limiting structure for steering column handles. The technical solution adopted includes an outer column cylinder assembly 1 and an angle adjustment bracket 2. The outer column cylinder assembly 1 has an angle adjustment bracket 2 on its outside. Angle adjustment grooves 201 are opened on both sides of the angle adjustment bracket 2. The outer column cylinder assembly 1 has recessed grooves 101 on both sides. The angle adjustment grooves 201 are located on both sides of the recessed grooves 101. A locking long bolt 3 passes through the recessed grooves 101 and the angle adjustment grooves 201 to make them a whole.
[0020] The axial soft limit block 4 slides into the recess 101. A countersunk hole 401 is formed in the center of the axial soft limit block 4. Noise-reducing blocks 402 are located on both sides of the axial soft limit block 4. The axial soft limit block 4 is made of PA6 engineering plastic to reduce friction noise. The noise-reducing blocks 402 are made of NBR. Made of rubber, used to reduce the impact noise of the axial soft limit block 4 when it is in the extreme position. The locking bolt 3 passes through the axial soft limit block 4. The locking bolt 3 also has a first locking member 6. There is a locking spring 5 between the first locking member 6 and the axial soft limit block 4. The locking spring 5 slides onto the locking bolt 3. One end of the locking spring 5 is located inside the recess 101, and the other end is in contact with the first locking member 6. There is a second locking member 8 on the other side of the first locking member 6. There is a buffer ring 11 between the first locking member 6 and the second locking member 8. A fixing groove 7 is opened in the middle of the first locking member 6. The buffer ring 11 is fixed to the inside of the fixing groove 7. There is a handle 9 on the right side of the second locking member 8. There are nuts on both sides of the locking bolt 3. The nuts include a self-locking nut 10 screwed to the end of the handle 9 side of the locking bolt 3 and a locking nut 301 screwed to the other end.
[0021] The working principle of this utility model is as follows: When it is necessary to adjust the angle of the outer tube column assembly 1, rotate the handle 9. Due to the elastic deformation of the angle adjustment bracket 2, the protrusion 103 suddenly enters the groove 102. The first locking member 6 and the second locking member 8 will slowly contact each other through the buffer ring 11 to reduce the collision noise. At this time, the locking spring 5 will push against the first locking member 6 and the second locking member 8 on the side of the handle 9, thereby reducing the gap on both sides of the handle 9 and preventing the handle 9 from shaking. When adjusting the outer tube column assembly 1, the locking long bolt 3 will slide inside the groove 101 through the axial soft limit block 4. When it moves to the limit position, it will contact the noise reduction block 402 to prevent the generation of collision noise. When the outer tube column assembly 1 is adjusted, rotate the handle 9 in the opposite direction to make the protrusion 103 disengage from the groove 102, thereby squeezing the angle adjustment bracket 2 to fix the outer tube column assembly 1.
[0022] The mechanical connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It is common knowledge.
[0023] Components not described in detail in this article are existing technologies.
