Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and in particular relates to an upper support for rapid assembly of a stamping plate bracket and an assembling method thereof. Background Art

[0002] Automobiles are equipped with shock absorbers, which typically have a threaded rod or mounting bracket at the top for connection to an upper support. The upper support is fixed to the vehicle body and has a hole in the center for mounting the shock absorber. This connection ensures a secure connection between the shock absorber and the vehicle body, improving driving comfort and safety. Existing automobile upper supports have the following disadvantages:

[0003] 1. Durability issues

[0004] Material fatigue: Metal or rubber parts are prone to fatigue due to long-term vibration and impact, leading to cracking or deformation;

[0005] Rubber aging: Rubber parts age over time, their elasticity decreases, and the shock absorption effect is affected.

[0006] 2. Noise problem

[0007] Abnormal noise: Loose or worn connections can produce abnormal noise, affecting the driving experience;

[0008] Resonance: Poor design may cause resonance and increase noise inside the car.

[0009] 3. High maintenance costs

[0014] Weight issues: Some designs increase weight to increase strength, affecting fuel economy.

[0015] 5. High installation accuracy requirements

[0016] Improper installation affects performance: Installation errors can cause the shock absorber to malfunction or even damage other components.

[0017] Specialized tools required: Installation and adjustments often require specialized tools and equipment.

[0018] 6. Poor environmental adaptability

[0019] Impact of extreme temperatures: In high or low temperature environments, the performance of rubber and metal will deteriorate, affecting service life and performance.

[0020] These shortcomings indicate that there is still room for improvement in the existing upper supports in terms of durability, noise, maintenance cost, performance, installation accuracy and environmental adaptability.

[0021] Traditionally, stamped plate brackets are usually connected by welding or bolts. The welding process is complex, the production efficiency is low, and stress concentration is easily generated at the weld, affecting the overall strength of the bracket. The bolt connection method requires pre-punching, the assembly steps are cumbersome, and the bolts are prone to loosening, affecting the stability of the bracket. How to design and provide bracket connectors to improve quality and reduce the impact on the entire vehicle is a technical problem that we urgently need to solve. Summary of the Invention

[0051] Example 1

[0052] 1. Overall structure

[0053] A quick-assembled upper support for the stamping plate bracket includes an upper plate 1, a lower plate 2, a cup body 3, a bolt 4, an inner core 5, a rubber body 6 and an outer tube 7. The upper plate 1 is connected to an external load via a bolt 4. The lower plate 2 is overlapped at the lower part of the upper plate 1. The middle of the upper plate 1 and the lower plate 2 bulges outwards at both ends to form an internal cavity. A rubber body 6 is provided in the cavity. The middle of the rubber body 6 is provided with an inner core 5 connected to the external connection. The outer periphery of the rubber body 6 is provided with an outer tube 7 connected to the inner wall of the cavity. The bolt 4 passes through the lower plate 2 and is riveted together with the upper plate 1.

[0054] 2. Connection of upper and lower boards

[0055] To overcome material fatigue, such as Figure 3 and Figure 4As shown, the upper plate 1 and the lower plate 2 are riveted together by bolts 4, which effectively overcomes the stress generated at the weld caused by the original welding method. Riveting can not only connect the upper plate 1 and the lower plate 2 together, but also maintain their respective toughness and avoid stress concentration. In order to prevent the rubber parts from aging over time and decreasing their elasticity, which affects the shock absorption effect, the rubber part 6 is placed in the middle of the upper plate 1 and the lower plate 2. The defect of being exposed to the outside and easily aging can be avoided, the adaptability to the environment is improved, and the durability problem mentioned in the background technology can be effectively solved.

[0056] Preferably, if Figure 3 、 Figure 4 As shown, the overlapping surfaces of the upper plate 1 and the lower plate 2 intersect with the core axis of the inner core 5 at an acute angle, not vertically. The angle is usually between 60 and 90 degrees to adapt to the installation of the vehicle body, reduce noise generation, and improve installation accuracy.

[0057] 3. Setting of rubber parts

[0058] Preferably, if Figure 3 As shown, the rubber body 6, the inner core 5 and the outer tube 7 are formed into an integral body through a vulcanization process. In this way, the inner core 5 and the outer tube 7 can form a whole with the rubber body 6. The connection is tight and the elasticity of the connection is better, which avoids looseness or wear and produces abnormal noise, affecting the driving experience, effectively avoiding the generation of resonance, and reducing the noise inside the car.

[0059] 4. Installation and connection of rubber parts and upper and lower plates

[0060] Preferably, if Figure 3 、 Figure 4 As shown, the outer walls of the cavities in the middle of the upper plate 1 and the lower plate 2 are combined to form a cylindrical shape, and the inner diameters of the cylinders are the same, which is convenient for the installation and connection of the outer tube 7. The outer wall of the outer tube 7 is tightly connected to the inner wall of the cavity formed by the combination of the upper plate 1 and the lower plate 2. A separation groove is provided between the inner wall of the outer tube 7 and the two end faces of the rubber body 6, so that the rubber body 6 has a larger swing space and can better absorb vibrations, which can effectively solve the technical problem of poor environmental adaptability mentioned in the background technology part, and the outer tube 7 can improve the rubber body's ability to absorb vibrations transmitted by the vehicle body in a larger range, thereby improving comfort, not only enhancing strength without increasing weight, but also improving fuel economy, and effectively overcoming the performance limitations mentioned in the background technology; combined with Figure 2 、 Figure 3 The upper plate 1 and the lower plate 2 are riveted at the joints with bumps 8 for easy connection. Figure 7The protrusion 8 is provided with a rivet hole 9, and the bolt 4 passes through the rivet hole 9 to rivet the protrusions 8 of the upper plate 1 and the lower plate 2 together at the root, with the head extending upward; it can effectively solve the defect of high maintenance cost mentioned in the background technology part. During maintenance, it is only necessary to remove the nut on the bolt 4 and lift the car body to replace the upper support. The replacement is fast and the cost is low.

[0061] 5. Positioning connection of upper and lower plates

[0062] Preferably, if Figure 1 、 Figure 2 As shown, the upper plate 1 and the lower plate 2 are further provided with connecting holes 10 arranged circumferentially staggered with the rivet holes 9, and the upper plate 1 is further provided with a positioning sleeve extending into the connecting hole 10 of the lower plate 2, so as to facilitate the quick alignment of the upper plate 1 and the lower plate 2 for installation, which can effectively solve the deficiency of high installation precision requirements mentioned in the background technology, does not require special tools and equipment, and is more convenient to assemble.

[0063] 6. Connection with external devices

[0064] Preferably, if Figure 3 、 Figure 9 As shown, the lower plate 2 is provided with a cup body 3 arranged back to back with the outer wall of the cavity of the lower plate 2 on the side away from the upper plate 1, which is convenient for the installation and connection of the inner core 5 and the piston rod of the shock absorber. The rubber body 6 is arranged in a ring shape, and its two ends are provided with convex bumps 11 protruding outward at uniform intervals. The convex bumps 11 abut against the inner end surfaces of the two ends of the cavity wall of the upper plate 1 and the lower plate 2, playing a supporting role, which can effectively prevent the rubber body 6 from being torn, and improve the service life of the rubber body 6.
