Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a side structure of an automotive body. Background Technology
[0002] As a core component of the vehicle body, the side structure of a car body is a key load-bearing and protective frame connecting the front, rear, and top of the vehicle. Its design performance is directly related to the vehicle's safety, comfort, handling stability, and durability. With the continuous development of the automotive industry, consumers' requirements for the comprehensive performance of vehicles are increasing, thus necessitating a new type of side structure for the car body.
[0003] Existing automotive side panel structures often use single bolts or simple welding to fix the seatbelt base during operation, lacking an effective force distribution structure. In a collision, the thousands of Newtons of tensile force generated by the seatbelt are concentrated at the base connection point. The side panel below the traditional base is supported only by a single longitudinal reinforcing rib, resulting in a single force transmission path. Traditional side panels are single-layer thin metal sheets lacking sound insulation material, allowing vibrations from the engine and road bumps to be directly transmitted to the passenger compartment. To ensure smooth adjustment, traditional structures leave a relatively large gap of 0.5-1mm between the guide rail and the seatbelt base slider. When the vehicle travels on bumpy roads, periodic relative motion occurs between the slider and the guide rail, causing the metal parts to collide and produce a "ticking" sound. This noise is particularly noticeable at low frequencies (10-30Hz), and the gap widens with wear over time, exacerbating the noise problem. Therefore, a new automotive side panel structure is urgently needed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a side panel structure for automobiles to address the problems of existing side panel structures. Traditional side panel seatbelt bases often use single bolts or simple welding for connection, lacking an effective force distribution structure. When a collision occurs, the thousands of Newtons of tensile force generated by the seatbelt are concentrated at the base connection point. The side panel below the traditional base is supported only by a single longitudinal reinforcing rib, resulting in a single force transmission path. Furthermore, traditional side panels are single-layer thin metal sheets lacking sound insulation material. Vibrations from the engine and road bumps are directly transmitted to the passenger compartment through the side panel metal parts. To ensure smooth adjustment, traditional structures leave a relatively large gap of 0.5-1mm between the guide rail and the seatbelt base slider. When the vehicle travels on bumpy roads, periodic relative motion occurs between the slider and the guide rail, causing the metal parts to collide and produce a "ticking" sound. This noise is particularly noticeable under low-frequency vibrations (10-30Hz), and the gap widens due to wear over time, exacerbating the noise problem.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a side panel structure for an automobile body, including a side panel, wherein a reinforcing rib is fixedly connected to the inner wall of the side panel, and sound insulation cotton is installed on the inner wall of the side panel.
[0006] A guide rail is fixedly connected to the side wall of the side panel. A slider is installed on the inner wall of the guide rail fixedly connected to the side wall of the side panel. A seat belt base is fixedly connected to the side wall of the slider. A sleeve post is fixedly connected to the side wall of the seat belt base. An insertion rod is installed on the inner wall of the sleeve post. A return spring is installed on the outer wall of the insertion rod. A pressure plate is fixedly connected to one end of the insertion rod.
[0007] Preferably, the reinforcing ribs are honeycomb shaped and are tightly fitted with the sound insulation cotton.
[0008] Preferably, the sound insulation cotton is arranged symmetrically along the central axis of the reinforcing ribs, and the sound insulation cotton is bonded to the side panel.
[0009] Preferably, the insertion rod is movably connected to the sleeve post, and the insertion rod is sleeved with the return spring.
[0010] Preferably, the clamping plate forms a telescopic structure with the slider via a return spring, and the clamping plate is in close contact with the guide rail.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the setting of side panels, reinforcing ribs and sound insulation cotton, and the setting of honeycomb reinforcing ribs, the honeycomb reinforcing ribs, through the mutual support of grid units, disperses the tensile force, shear force or bending force received to multiple grid nodes, forming a mechanical transmission path of "multi-point force-overall bearing", thereby improving the shear strength and strengthening the protective function of the device. The flexible matrix of the sound insulation cotton can reduce the vibration transmission of the side panels through the damping effect, and can block the vibration of metal parts through solid conduction, preventing noise from entering the cabin and providing a quiet cabin environment for the driver and passengers.
[0013] 2. This utility model, through the setting of guide rail, slider, seat belt base, sleeve post, insert rod, return spring and pressure plate, inserts the rod, return spring and pressure plate between the guide rail and slider. The elastic force of the return spring makes the pressure plate fit tightly against the guide rail, which can eliminate the gap between the guide rail and slider. At the same time, the pressure plate 10 is made of wear-resistant material (such as nylon), which does not affect the smoothness of adjustment. When subjected to vibration and impact, the pressure plate is stressed and drives the insert rod to retract into the sleeve post, and at the same time drives the return spring to compress. The elasticity of the return spring can buffer the vibration and impact, thus protecting the seat belt base. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0020] The embodiments of this utility model will be described below based on its overall structure.
[0021] Please see Figures 1-4 A side panel structure for an automobile body includes a side panel 1, with reinforcing ribs 2 fixedly connected to the inner wall of the side panel 1, and sound insulation cotton 3 installed on the inner wall of the side panel 1. The reinforcing ribs 2 are honeycomb-shaped and are tightly fitted with the sound insulation cotton 3. The sound insulation cotton 3 is symmetrically arranged around the central axis of the reinforcing ribs 2 and is bonded to the side panel 1. When the device is in use, the honeycomb-shaped reinforcing ribs 2, through the mutual support of the grid units, distribute the tensile force, shear force, or bending force to multiple grid nodes, forming a mechanical transmission path of "multi-point force-overall bearing", thereby improving the shear strength. The porous fiber structure of the sound insulation cotton 3 can consume sound wave energy through air resistance and fiber vibration, and can block the vibration of metal parts through solid conduction, preventing noise from entering the cabin.
[0022] Please see Figures 1-4A side panel structure for an automobile body includes a side panel 1 with a guide rail 4 fixedly connected to its side wall. A slider 5 is installed on the inner wall of the guide rail 4, and a seat belt base 6 is fixedly connected to the side wall of the slider 5. A sleeve post 7 is fixedly connected to the side wall of the seat belt base 6, and an insert rod 8 is installed on the inner wall of the sleeve post 7. A return spring 9 is installed on the outer wall of the insert rod 8, and a pressure plate 10 is fixedly connected to one end of the insert rod 8. The insert rod 8 is movably connected to the sleeve post 7 and is sleeved with the return spring 9. The pressure plate 10 and the slider 5 form a telescopic structure through the return spring 9, and the pressure plate 10 is tightly fitted to the guide rail 4. When using the device, during daily seat belt height adjustment, the preload of the return spring 9 is transmitted to the pressure plate 10 through the insert rod 8, causing the pressure plate 10 to tightly fit against the inner wall of the guide rail 4's groove, completely eliminating the gap between the slider 5 and the guide rail 4. At this time, the friction generated during the adjustment process is borne by the wear-resistant coating on the surface of the clamping plate 10. When subjected to external vibration and impact, the impact and vibration are transmitted to the slider 5 through the safety belt base 6, causing the slider 5 to tend to move towards the end of the guide rail 4. The friction between the clamping plate 10 and the guide rail 4 increases sharply. At the same time, the insertion rod 8 is compressed by the axial force to the return spring 9. The elasticity of the return spring 9 can buffer the vibration and impact, which not only solves the problem of gap noise in the traditional adjustment mechanism, but also improves the protection capability under vibration and impact conditions.
[0023] Working Principle: In use, first move the device to a suitable position. During use, the honeycomb reinforcing ribs 2, through mutual support of the grid units, distribute the tensile, shear, or bending forces on the base to multiple grid nodes, thereby improving shear strength. The porous fiber structure of the sound-absorbing cotton 3 dissipates sound wave energy through air resistance and fiber vibration, blocking the transmission of metal component vibrations through solids and preventing noise from entering the cabin. Then, the preload of the return spring 9 is transmitted to the pressure plate 10 via the insertion rod 8, tightly fitting the pressure plate 10 against the guide rail 4, eliminating the gap between the guide rail 4 and the slider 5. When subjected to vibration and impact, the pressure plate 10 is stressed and drives the insertion rod 8 back into the sleeve 7, simultaneously compressing the return spring 9. The elasticity of the return spring 9 buffers the vibration and impact, protecting the seatbelt base 6. This completes the device's operation.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
