Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive handle technology, and specifically relates to a tilt handle gap-eliminating structure. Background Technology
[0002] In the steering column assembly, when the camber lever is opened, a gap is created between the brackets to facilitate adjustments to the camber and extension direction of the steering column. However, this gap can cause the lever to vibrate or even produce abnormal noises during adjustments, leading to customer dissatisfaction. Traditional methods for eliminating backlash often involve adding a compression spring between the cams, but this has limitations such as space constraints. Therefore, there is an urgent need for a simple, automatically compensating backlash elimination device. Utility Model Content
[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a tilt handle gap-eliminating structure. This invention features a simple structure that automatically compensates for gaps, ensuring that the handle does not vibrate during tilt and extension adjustments of the tubing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution.
[0005] This utility model provides a tilt handle backlash elimination structure, including a fixed bracket and a rotating bracket mounted on the outside of the fixed bracket. A bolt shaft is provided through the fixed bracket and the rotating bracket, and the end of the bolt shaft is connected to a tilt handle cam assembly. The rotating bracket has a spring support seat on its outside, a spring is provided in the inner cavity of the spring support seat, an end face bearing assembly and a locking nut are provided on the outside of the spring, and the threaded end of the bolt shaft on the other side passes through the spring support seat, the spring and the end face bearing assembly, and the locking nut is tightened onto the bolt shaft.
[0006] Furthermore, the inner cavity of the compression spring support is provided with a countersunk hole, and the compression spring is assembled on one side of the larger hole of the countersunk hole, providing a mounting base for the compression spring.
[0007] Furthermore, the bolt shaft is provided with a mating surface that mates with the small hole in the countersunk hole.
[0008] The beneficial effects of this utility model.
[0009] This invention adds a compression spring between the planar thrust bearing and the bracket to eliminate backlash. The elastic force of the compression spring automatically compensates for the gap, eliminating the need for manual adjustment. This ensures that the handle will not vibrate during the tilting and telescopic adjustment of the tubing column. The structure is simple and highly versatile. Attached Figure Description
[0010] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Detailed Implementation
[0015] As shown in the accompanying drawings, this embodiment provides a tilt handle backlash elimination structure, including a fixed bracket 3 and a rotating bracket 4 mounted on the outside of the fixed bracket 3. A bolt shaft 2 is provided through the fixed bracket 3 and the rotating bracket 4, and the end of the bolt shaft 2 is connected to the tilt handle cam assembly 1.
[0016] A spring support seat 5 is provided on the outer side of the rotating bracket 4. The inner cavity of the spring support seat 5 is provided with a countersunk hole 9. A spring 6 is installed on one side of the large hole of the countersunk hole 9 to provide a mounting base for the spring 6. A mating surface 10 is provided on the bolt shaft 2 to mate with the small hole of the countersunk hole 9. An end face bearing assembly 7 and a locking nut 8 are provided on the outer side of the spring 6. The threaded end of the bolt shaft 2 passes through the spring support seat 5, the spring 6 and the end face bearing assembly 7, and the locking nut 8 is tightened on the bolt shaft 2.
[0017] The spring 6 has an elastic coefficient designed according to the handle load. It is used to continuously apply appropriate thrust to eliminate gaps. Different handle models can be adapted simply by adjusting the parameters of the spring 6, making it highly versatile.
[0018] When the tilt handle is opened, a gap is created between the fixed bracket 3 and the rotating bracket 4. The compression spring 6 is compressed, generating a reverse elastic force, which pushes the tilt handle cam assembly 1 to tightly fit against the rotating bracket 4 through the end face bearing assembly 7, eliminating the gap in real time. After the locking nut 8 is tightened, the compression spring 6 is maintained under preload to prevent the elasticity from weakening after long-term use.
[0019] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
