Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive polyurethane buffer block bracket. Background Technology

[0002] The automotive polyurethane bumper bracket, also known as the suspension limiter bracket, primarily functions to secure the polyurethane bumper block, limiting tire bounce and protecting the vehicle's damping system and tires. Specifically, it assists the polyurethane bumper block in preventing excessive tire bounce, thus avoiding shock absorber puncture and oil leakage, and also preventing tire impact with the vehicle body from causing damage to itself or the vehicle body.

[0003] Traditional polyurethane buffer block supports are mostly made of steel, which has a simple structure and poor corrosion resistance. This cannot effectively improve the service life of the polyurethane buffer block, thus reducing its buffering and limiting functions.

[0004] Therefore, it is necessary to design a car polyurethane buffer block bracket to reduce the risk of polyurethane buffer blocks deforming and falling off after being subjected to impact, while improving strength to protect the buffer and limiting functions of the polyurethane buffer blocks from being affected. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automotive polyurethane buffer block bracket to reduce the risk of polyurethane buffer blocks deforming and falling off after being subjected to impact, while improving strength and achieving the effect of protecting the buffer and limiting functions of the polyurethane buffer blocks from being affected.

[0006] To achieve the above objectives, this utility model is an automotive polyurethane buffer block bracket, comprising a plastic cover and a steel sleeve. The steel sleeve is installed in the central through hole at the top of the plastic cover. The upper surface of the plastic cover is provided with two annular reinforcing ribs, and the side surface of the plastic cover is provided with several protruding reinforcing ribs. The reinforcing ribs are arranged along the axial direction of the plastic cover. The upper end of the reinforcing rib is connected to the annular reinforcing rib, and the lower end of the reinforcing rib is connected to the bottom edge of the plastic cover. The bottom inner ring of the plastic cover is provided with an inwardly folded barb structure.

[0007] The plastic cover is an injection-molded structure.

[0008] The two ring-shaped reinforcing ribs are ring-shaped reinforcing rib one and ring-shaped reinforcing rib two. Ring-shaped reinforcing rib one is located at the upper edge of the plastic cover, and ring-shaped reinforcing rib two is located between ring-shaped reinforcing rib one and the through hole of the plastic cover.

[0009] The plastic cover is installed at the bottom of the frame, and a polyurethane buffer block is installed inside the plastic cover. The barbed structure abuts against the lower surface of the polyurethane buffer block.

[0010] The plastic cover is fixed to the frame with bolts and nuts. The nuts are welded to the frame, and the bolts pass through the steel sleeve and are then tightened with the nuts.

[0011] The bolts and nuts mentioned are of specification M10.

[0012] The number of reinforcing ribs is 16.

[0013] Compared with existing technologies, this utility model uses a plastic cover to fix the polyurethane buffer block with a barbed structure, preventing the polyurethane buffer block from deforming and falling off after being impacted on bumpy roads. This avoids excessive tire bounce, which could lead to shock absorber breakdown, oil leakage, and failure. It also prevents the tire from impacting the vehicle body and causing damage to itself or the vehicle body. It protects the car's polyurethane buffer block. The reinforcing ribs and steel sleeves of the plastic cover ensure the overall strength of the bracket, achieving the protective function of the polyurethane buffer block.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] See Figure 1 , Figure 2 This utility model is a car polyurethane buffer block bracket, including a plastic cover and a steel sleeve. The top central through hole of the plastic cover 1 is provided with a steel sleeve 2. The upper end face of the plastic cover 1 is provided with two ring reinforcing ribs 11. The side of the plastic cover 1 is provided with several protruding reinforcing ribs 12. The reinforcing ribs 12 are arranged along the axial direction of the plastic cover 1. The upper end of the reinforcing rib 12 is connected to the ring reinforcing rib 11, and the lower end of the reinforcing rib 12 is connected to the bottom edge of the plastic cover 1. The bottom inner ring of the plastic cover 1 is provided with a ring of inwardly folded barb structure 13 for locking the polyurethane buffer block.

[0020] The plastic cover 1 is an injection-molded structure, and the plastic cover 1 is made of plastic, which has good corrosion resistance.

[0021] The two annular reinforcing ribs 11 are called Annular Reinforcing Rib 1 and Annular Reinforcing Rib 2. Annular Reinforcing Rib 1 is located at the upper edge of the plastic cover 1, and Annular Reinforcing Rib 2 is located between Annular Reinforcing Rib 1 and the through hole of the plastic cover 1. There are 16 reinforcing ribs 12. The annular reinforcing ribs and reinforcing ribs can effectively improve the strength and rigidity of the polyurethane buffer block support.

[0022] See Figure 3 , Figure 4 The plastic cover 1 is installed at the bottom of the frame 3. A polyurethane buffer block is installed inside the plastic cover 1. A hook structure 13 abuts against the lower surface of the polyurethane buffer block to prevent it from deforming and falling off due to impact on bumpy roads. A polyurethane plastic bracket is located between the polyurethane buffer block and the frame. The plastic cover 1 is fixed to the frame 3 using bolts 4 and nuts 5. Nuts 5 are welded to the frame 3. Bolts 4 pass through the steel sleeve 2 and are then tightened with nuts 5. Bolts 4 and nuts 5 are M10.

[0023] This utility model has undergone topology optimization testing through CAE simulation. The frame not only meets the requirements for overall height and weight reduction, but also the requirements for strength.

[0024] In this invention, the plastic cover uses a hook structure to fix the polyurethane buffer block, preventing it from deforming and falling off after impact on bumpy roads. This avoids excessive tire bounce, which could lead to shock absorber failure and oil leakage. It also prevents the tire from impacting the vehicle body and causing damage to itself or the vehicle body. The plastic cover's reinforcing ribs and steel sleeve ensure the overall strength of the bracket, achieving the protective function for the polyurethane buffer block.
