Description

Technical Field

[0001] This utility model relates to the field of automotive interior ambient lighting technology, and in particular to an anti-noise mounting structure for automotive ambient lighting. Background Technology

[0002] Automotive ambient lights are typically long, strip-shaped LED light strips. During installation, they need to be inserted into a slot on a guide rail from one end. To facilitate assembly, a certain gap must be left between the ambient light and the slot. Due to this gap, the light strip is prone to swaying in vibrating environments and colliding with the inner wall of the slot, producing abnormal noise. To suppress this noise, traditional solutions usually involve minimizing the assembly gap as much as possible. This not only makes assembly difficult and time-consuming but also requires extremely high precision control of the part dimensions, resulting in high production and quality control costs. Utility Model Content

[0003] The purpose of this invention is to provide an anti-noise installation structure for automotive ambient lights, so as to solve the technical problem that automotive ambient lights are prone to generating noise in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model discloses an anti-noise installation structure for automotive ambient lights, characterized in that it includes a guide rail and an elastic pretensioner. The guide rail has a groove for accommodating a flexible, elongated ambient light strip. The end of the groove includes a sealing strip. The ambient light strip is inserted into the groove from the inlet end. The elastic pretensioner is disposed between the sealing strip and the end of the ambient light strip. The front end of the ambient light strip is axially limited between the front end of the ambient light strip and the groove by an axial limiting mechanism.

[0006] A further improvement is that the elastic preload is a helical spring or an elastic rubber strip.

[0007] A further improvement is that the outer diameter of the helical spring or elastic rubber strip is smaller than the size of the groove.

[0008] A further improvement is that the sealing strip is formed by bending inward from the groove wall of the pipe.

[0009] A further improvement is that the guide rail is made of lightweight metal or alloy material or injection molded material.

[0010] A further improvement is that the alloy material is an aluminum alloy.

[0011] A further improvement is that the front end of the ambient light strip is provided with a snap-on cover for connection, and the snap-on cover is snapped into the axial limiting mechanism.

[0012] A further improvement is that the front end of the ambient light strip is electrically connected to the vehicle control unit via an electrical connection terminal.

[0013] Because this utility model adopts the above technical solution, it has the following beneficial effects:

[0014] This invention utilizes a sealing strip and an elastic pre-tightening element at the end of the tube groove. The elastic pre-tightening element, when compressed by the ambient light strip, generates axial elastic force, causing the slender ambient light strip to undergo a slight elastic bend within the tube groove. The slight bend of the ambient light strip fits tightly against the inner wall of the tube groove, effectively eliminating the gap required for assembly and resolving the noise problem. By employing extrusion deformation to ensure a tight fit between the ambient light strip and the inner wall of the tube groove, the assembly gap between the two can be increased, making insertion and assembly easier and less strenuous. Increasing the assembly gap significantly widens the dimensional tolerances of the ambient light strip and the tube groove, greatly reducing production costs. Attached Figure Description

[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.

[0019] like Figures 1 to 3As shown, this utility model provides an anti-noise installation structure for automotive ambient lights, including a guide rail 1 and an elastic pretensioner 2. The guide rail 1 has a groove 11 for accommodating a flexible elongated ambient light strip 3. The end of the groove 11 includes a sealing strip 12. The ambient light strip 3 is inserted into the groove 11 from the inlet end of the groove 11. The elastic pretensioner 2 is disposed between the sealing strip 12 and the end of the ambient light strip 3. The front end of the ambient light strip 3 is axially limited between the front end of the ambient light strip 3 and the groove 11 by an axial limiting mechanism (not shown in the figure). After axial limiting, the elastic force generated by the elastic pretensioner 2 can be effectively locked. The front end of the ambient light strip is electrically connected to the vehicle control unit through an electrical connection terminal.

[0020] Preferably, the elastic preload 2 is a helical spring or an elastic rubber strip.

[0021] A further improvement is that the outer diameter of the helical spring or elastic rubber strip is smaller than the size of the groove 11.

[0022] A further improvement is that the sealing strip 12 is formed by bending inward from the groove wall of the tube groove 11.

[0023] A further improvement is that the guide rail 1 is made of lightweight metal or alloy material or injection molded material.

[0024] Preferably, the alloy material is an aluminum alloy.

[0025] Specifically, the front end of the ambient light strip 3 is provided with a snap cover for connection, and the snap cover is snapped together with the axial limiting mechanism.

[0026] This invention utilizes a sealing strip and an elastic pre-tightening element at the end of the tube groove. The elastic pre-tightening element, when compressed by the ambient light strip, generates axial elastic force, causing the slender ambient light strip to undergo a slight elastic bend within the tube groove. The slight bend of the ambient light strip fits tightly against the inner wall of the tube groove, effectively eliminating the gap required for assembly and resolving the noise problem. By employing extrusion deformation to ensure a tight fit between the ambient light strip and the inner wall of the tube groove, the assembly gap between the two can be increased, making insertion and assembly easier and less strenuous. Increasing the assembly gap significantly widens the dimensional tolerances of the ambient light strip and the tube groove, greatly reducing production costs.

[0027] The assembly process of this utility model consists of two steps: First, the elastic pre-tightening component 2 is pre-installed into the end of the pipe groove 11, so that the elastic pre-tightening component 2 is reliably limited by the sealing strip 12; then, the flexible elongated ambient light strip is inserted from the inlet end of the pipe groove 11 until the end of the ambient light strip 3 is in close contact with the elastic pre-tightening component 2. External force is then applied to snap the cover into the buckle hole of the pipe groove, completing the sealing. At this time, the elastic pre-tightening component 2 generates a continuous axial elastic force due to compression. This elastic force acts directly on the ambient light strip, forcing the slender strip structure to undergo slight elastic bending within the pipe groove, thus transforming it from a loose, freely swaying state to a taut, axially compressed state with uniform internal stress. This eliminates the gap between the entire ambient light strip and the inner wall of the pipe groove. It effectively transforms the control dimension from the difficult-to-manage radial gap to the easily controllable and achievable axial pre-tightening force, suppressing relative displacement during vibration by actively applying internal stress, thereby completely eliminating abnormal noise.

[0028] It should be understood that the directional terms are established in combination with the daily operating habits of operators and users and the accompanying drawings in the instruction manual, and their appearance should not affect the scope of protection of this utility model.

[0029] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
