Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an environmentally friendly fender pad strip. Background Technology

[0002] The fender is the sheet metal shell of a vehicle. The fender mainly serves an aesthetic purpose. To enhance the stability of the fender, a pad strip is installed on the inside of the fender to reduce vibration.

[0003] The gap height between the fender and the frame varies (usually 5-15mm) for different car models, requiring the development of exclusive pads for each type of car model (independent mold design and separate production process debugging), resulting in a large number of molds, a lot of resource waste, and environmental pollution from discarded pads. Summary of the Invention

[0004] This utility model provides an environmentally friendly fender pad strip. The upper and lower pad frames are located between the fender and the vehicle frame. The lower pad frame moves along the threaded rod to shorten or raise the overall height of the upper and lower pad frames, achieving compatibility with the space height of fenders and vehicle frames of different models. By adjusting the angle of the side bracket, the bending angle of the upper rubber pad strip can be changed, allowing the upper rubber pad strip to adapt to the curved shape of the fender, achieving compatibility with fenders of different curvatures of different models, reducing the number of molds required, and making it more energy-efficient and environmentally friendly.

[0005] This utility model provides an environmentally friendly fender pad strip, specifically including: an upper plate pad frame, a lower plate pad frame, and side supports. The lower plate pad frame is slidably connected to the lower plate pad frame, and side supports are provided on both sides of the lower plate pad frame. An upper rubber pad strip is fixedly connected to the top of the upper plate pad frame. Both the upper plate pad frame and the lower plate pad frame are made of plastic. Side connecting brackets are fixedly connected to both sides of the bottom of the upper rubber pad strip.

[0006] Furthermore, the middle part of the upper rubber pad is fixedly connected to the upper plate pad frame, and the two sides of the upper rubber pad extend to the outer side of the upper plate pad frame. The upper rubber pad is attached to the inner side of the fender, and the upper rubber pad absorbs the vibration energy of the fender.

[0007] Furthermore, a lower rubber pad is fixedly connected to the bottom of the lower plate pad frame. Both the upper and lower rubber pads are made of recycled nitrile rubber (containing ≥60% recycled material and VOC emissions ≤50g / L). Neither the upper nor the lower rubber pad contains heavy metals (lead and mercury content <10ppm), which meets the requirements of "Requirements for Prohibited Substances in Automobiles" (GB / T 30512). This ensures that the pads do not pollute the environment after disposal, and the upper rubber pad can be disassembled and recycled separately, improving resource utilization. A central threaded rod is rotatably connected to the upper part of the lower plate pad frame. Side connecting grooves are opened on both sides of the lower plate pad frame, and side connecting sliding columns are slidably connected inside the side connecting grooves.

[0008] Furthermore, the central threaded rod and the upper plate pad are connected by a central thread, and the rectangular tube at the top of the lower plate pad slides and slides onto the upper plate pad. When the central threaded rod rotates, the lower plate pad moves along the axial direction of the central threaded rod (perpendicular to the fender surface), with a movement range of 0-10mm, adapting to the installation requirements of fenders of different lengths, ensuring that both the upper and lower rubber pads can fit tightly against the fender and the vehicle body, avoiding situations where the thickness is mismatched.

[0009] Furthermore, the tail end of the side bracket is rotatably connected to the lower positioning frame pin, and the head end of the side bracket is rotatably connected to the side connecting frame pin.

[0010] Furthermore, the upper end of the side connecting slide column is threaded with a positioning nut, and the positioning nut and the middle of the lower positioning frame are connected through the nut. As the lower positioning frame and the side connecting slide column move, the side bracket moves closer to the middle of the upper plate pad frame. The upper end of the side bracket is lowered, and the side bracket drives the upper rubber pad strip to bend and deform downwards in sync, fitting the arc-shaped surface of the fender of different vehicle models.

[0011] Furthermore, the bottom of the lower positioning frame is attached to the top of the lower plate pad frame, the positioning nut is pressed on the top of the lower positioning frame, and the position of the side connecting slide column is fixed in the side connecting slide groove, thereby locking the position of the lower positioning frame.

[0012] This utility model provides an environmentally friendly fender pad strip, which has the following beneficial effects:

[0013] The upper and lower plate pads are located between the fender and the frame. The lower plate pad moves along the central threaded rod to shorten or raise the overall height of the upper and lower plate pads, achieving compatibility with the space height of the fender and frame for different vehicle models, reducing the types of fender pads for different models, reducing the number of molds, and making it more energy-efficient and environmentally friendly.

[0014] By adjusting the angle of the side bracket, the bending angle of the upper rubber pad can be changed, allowing the upper rubber pad to adapt to the curved shape of the fender, achieving compatibility with fenders of different curvatures on different car models, reducing the number of molds required, and making it more energy-efficient and environmentally friendly.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes an environmentally friendly fender pad strip, including an upper pad frame 1, a lower pad frame 2, and side supports 3. An upper rubber pad strip 101 is fixedly connected to the top of the upper pad frame 1. Both the upper pad frame 1 and the lower pad frame 2 are made of plastic. Side connecting brackets 102 are fixedly connected to both sides of the bottom of the upper rubber pad strip 101. The middle part of the upper rubber pad strip 101 is fixedly connected to the upper pad frame 1. The upper rubber pad strip 101 extends to the outer side of the upper pad frame 1 on both sides and fits against the inner side of the fender. Rubber pad 101 absorbs the vibration energy of the fender. A lower fender pad 2 is slidably connected below the upper pad 1, and a lower rubber pad 201 is fixedly connected to the bottom of the lower pad 2. Both the upper rubber pad 101 and the lower rubber pad 201 are made of recycled nitrile rubber (containing ≥60% recycled material, with VOC emissions ≤50g / L). Neither the upper rubber pad 101 nor the lower rubber pad 201 contains heavy metals (lead and mercury content <10ppm), complying with the "Requirements for Prohibited Substances in Automobiles" (GB / T). 30512), achieving no environmental pollution after the pad strip is discarded, and the upper rubber pad strip 101 can be disassembled and recycled separately, improving resource utilization. The upper part of the lower plate pad frame 2 is rotatably connected with a central threaded rod 202. Both sides of the lower plate pad frame 2 are provided with side connecting grooves 203. The side connecting grooves 203 are slidably connected with side connecting slide columns 204. Both sides of the lower plate pad frame 2 are provided with side brackets 3. The tail end of the side bracket 3 is rotatably connected with the pin of the lower positioning frame 301. The head end of the side bracket 3 is rotatably connected with the pin of the side connecting rotating frame 102. The bottom of the lower positioning frame 301 is attached to the top of the lower plate pad frame 2. The positioning nut 205 is pressed on the top of the lower positioning frame 301 to fix the position of the side connecting slide column 204 in the side connecting groove 203, thereby locking the position of the lower positioning frame 301.

[0031] In this embodiment, the threaded rod 202 and the upper plate pad 1 with a rectangular block structure are threadedly connected at the middle. The rectangular tube at the top of the lower plate pad 2 slides and is slidably fitted with the upper plate pad 1. When the threaded rod 202 rotates, the lower plate pad 2 moves along the axial direction of the threaded rod 202 (perpendicular to the fender surface), with a movement range of 0-10mm, to adapt to the installation requirements of fenders of different lengths. This ensures that both the upper rubber pad 101 and the lower rubber pad 201 can fit tightly against the fender and the vehicle body, avoiding situations where the thickness is mismatched.

[0032] In this embodiment, the upper end of the side connecting slide column 204 is threaded with a positioning nut 205. The positioning nut 205 and the lower positioning frame 301 are connected through the middle. The side bracket 3 moves closer to the middle of the upper plate pad frame 1 as the lower positioning frame 301 and the side connecting slide column 204 move. The upper end of the side bracket 3 is lowered. The side bracket 3 drives the upper rubber pad strip 101 to bend and deform downwards in sync, fitting the arc-shaped surface of the fender of different vehicle models.

[0033] In this second embodiment, based on the first embodiment, the pin connection structure between the side bracket 3 and the upper plate pad 1 and the lower positioning frame 301 is detachable (without destructive disassembly). When the upper rubber pad 101 and the lower rubber pad 201 are partially aged and worn, the upper rubber pad 101 and the lower rubber pad 201 can be replaced separately without the need for complete scrapping, thus improving the overall resource utilization rate of the pads by 30%.

[0034] The working principle of this embodiment is as follows: Addressing the core pain point of traditional fender pad design's "model-specific design"—the gap height between the fender and the chassis varies across different vehicle models (typically 5-15mm), requiring the development of dedicated pads for each model (independent mold design and separate production process debugging). This results in a large number of molds, significant resource waste, and environmental pollution from discarded pads. This device achieves a breakthrough optimization through a height adjustment structure driven by the central threaded rod 202: It provides full coverage of gap heights for multiple vehicle models; rotating the central threaded rod 202 drives the lower plate pad 2 to move axially. The device moves, allowing the overall height of the upper plate support 1 and the lower plate support 2 to be precisely adjusted within the range of 0-10mm (adjustment accuracy ±0.1mm), which can adapt to the clearance height requirements of different vehicle models from 5 to 15mm (covering more than 80% of mainstream passenger car models and commercial light truck models); compared with the traditional solution (one set of dedicated molds is required for every 3 vehicle models, and a certain car company needs to develop 10 sets of molds per year), this device only requires 2 sets of basic molds (adapting to two ranges of 5-10mm and 10-15mm) to meet the needs of all vehicle models, greatly reducing the number of molds to be developed;

[0035] Significantly reduces resource consumption and environmental pollution: Traditional dedicated spacer strip molds require 150-200 kg of mold steel per set. This solution reduces mold development by 80%, saving 1200-1600 kg of mold steel annually (based on 10 sets of traditional molds developed per year). Simultaneously, traditional spacer strips need to be scrapped as car models are phased out (approximately 5000 pieces discarded annually per car manufacturer). This device can be reused across different car models (adapting to 3-5 different car model iterations within its service life), reducing the number of discarded spacer strips by 70%. Furthermore, the core material of the spacer strip is recycled nitrile rubber (containing ≥60% recycled materials), resulting in no heavy metal pollution after disposal (lead and mercury content <10ppm), and VOC emissions ≤50g / L, meeting the "Evaluation Requirements for Green Factories in the Automotive Industry" (GB / T39223).

[0036] Cost reduction, efficiency improvement, and environmental protection go hand in hand: The traditional solution costs about 80,000 to 120,000 yuan to develop a single mold. This device reduces the amount of mold development by 80%, saving 640,000 to 960,000 yuan in mold costs annually. At the same time, the inventory of pads does not need to be classified and stored according to vehicle models (traditionally 10 types of inventory are required, while this solution only requires 2 types), increasing the inventory turnover rate by 400%, reducing warehousing energy consumption and management costs, and achieving a dual improvement in "economic benefits and environmental benefits".

[0037] Addressing the pain point of traditional fender spacer strips' "limited curvature adaptation"—the curvature of fenders varies greatly across different vehicle models (e.g., sedan fender curvature radius R100-R200mm, SUV fender curvature radius R200-R500mm). Traditional spacer strips require mold forming to fix the curvature, which cannot adapt to multiple vehicle models, leading to a further increase in the number of molds. This device optimizes this through the triangular support of the side bracket 3: full coverage adaptation for multi-curvature fenders: the side bracket 3 adjusts its tilt angle as it moves with the lower positioning frame 301 and the side connecting slide column 204, through the "upper plate spacer"... The triangular support linkage of "Frame 1 - Side Support 3 - Lower Positioning Frame 301" drives the upper rubber pad strip 101 to bend and deform synchronously (the bending arc can cover R100-R500mm), accurately fitting the curved surface of the fender of different car models. Compared with the traditional solution (one set of special molds is required for every two types of curved fenders, and eight sets of molds need to be developed every year), this device only requires two sets of basic molds to meet the full curved requirements, further reducing the number of molds developed by 75%, and further saving mold steel consumption and processing energy consumption (saving 800-1000kg of mold steel per year).
