Shock-Absorbing Spring Suspension Mechanism

Technical Field

The utility model relates to the technical field of automotive suspension systems, and particularly to a shock-absorbing spring suspension mechanism.

Background Technology

Automotive suspensions are generally divided into independent suspensions and non-independent suspensions. In practical applications, independent suspensions provide better shock absorption performance than non-independent suspensions, but independent suspensions are usually more expensive, while non-independent suspensions offer relatively higher safety.

Existing spring shock-absorbing suspension mechanisms lack:

a mechanism capable of effectively damping vibrations between the support plate and the suspension arm;

a cleaning mechanism capable of cleaning the surface of the suspension arm by utilizing external vibration forces generated during shock absorption; and

a collision protection mechanism for protecting the suspension arm.

Therefore, it is necessary to provide a shock-absorbing spring suspension mechanism to solve the above technical problems.

Summary of the Utility Model

The utility model provides a shock-absorbing spring suspension mechanism, which solves the problems that existing spring suspension mechanisms:

cannot conveniently provide shock absorption between the support plate and the suspension arm;

cannot utilize external damping force to clean the surface of the suspension arm; and

lack a protective anti-collision mechanism for the suspension arm.

Technical Solution

The shock-absorbing spring suspension mechanism includes:

a suspension arm;

a movable connecting member connected to the outside of the suspension arm;

a connecting plate mounted on the outer side of the movable connecting member;

a support plate fixedly connected to the top end of the connecting plate;

a shock-absorbing mechanism arranged between the support plate and the suspension arm;

a cleaning mechanism connected between the shock-absorbing mechanism and the suspension arm; and

an anti-collision mechanism slidably mounted outside the suspension arm.

The Shock-Absorbing Mechanism Includes:

a first movable shaft;

a telescopic inner rod connected to the bottom end of the first movable shaft;

a first sliding block fixed on the outer wall of the telescopic inner rod;

a first sliding groove slidably connected with the first sliding block;

a fixed outer rod mounted outside the first sliding groove; and

a first spring arranged inside the fixed outer rod.

Preferably:

the telescopic inner rod forms a telescopic structure with the fixed outer rod through the first sliding block and the first sliding groove; and

the telescopic inner rod and the fixed outer rod form an elastic structure through the first spring.

Cleaning Mechanism

The cleaning mechanism includes:

a second movable shaft;

a connecting rod connected to the second movable shaft;

a third movable shaft mounted on the outer side of the connecting rod;

a movable brush ring fixed outside the third movable shaft;

a connecting column fixed on the inner wall of the movable brush ring;

a second sliding block fixed at the bottom end of the connecting column; and

a second sliding groove slidably connected with the second sliding block.

Preferably:

the movable brush ring forms a sliding structure with the suspension arm through the second sliding block and the second sliding groove; and

the movable brush ring forms a movable structure with the connecting rod through the third movable shaft.

Anti-Collision Mechanism

The anti-collision mechanism includes:

a third sliding groove;

a third sliding block slidably connected inside the third sliding groove;

a hand-tightened external threaded rod threaded inside the third sliding block;

a U-shaped protective plate movably connected outside the threaded rod; and

a second spring fixed inside the U-shaped protective plate.

Preferably:

the U-shaped protective plate forms a detachable structure with the third sliding block through the hand-tightened external threaded rod; and

the U-shaped protective plate forms an elastic structure with the suspension arm through the second spring.

Beneficial Effects

Compared with existing technologies, the utility model provides the following advantages:

1. Excellent Shock Absorption Performance

When the vehicle wheel encounters a hard object during operation, the suspension arm tilts upward through the movable connecting member and connecting plate. The suspension arm presses the fixed outer rod upward, while the telescopic inner rod slides into the fixed outer rod under the action of the support plate and movable shaft.

At this moment, the first spring is compressed. The rebound force generated by the compressed spring effectively absorbs vibration between the suspension arm and the support plate, thereby providing excellent damping performance and improving ride comfort.

2. Automatic Cleaning Function

During the compression movement of the telescopic inner rod into the fixed outer rod, the connecting rod connected to the second movable shaft pushes the movable brush ring connected through the third movable shaft.

The movable brush ring slides toward the wheel side, enabling the brushes arranged on its inner wall to clean the surface of the suspension arm automatically.

This design:

prevents dirt accumulation on the suspension arm;

improves cleanliness; and

extends service life.

3. Effective Collision Protection

When the bottom end of the suspension arm encounters sharp stones or hard objects, the U-shaped protective plate is pushed upward along the suspension arm.

At this time, the multiple second springs between the protective plate and suspension arm are compressed. The rebound force generated by the springs enables the protective plate to effectively protect the suspension arm from impact damage.

This structure:

prevents scratches and collision damage;

improves durability; and

provides excellent protective performance.

Working Principle

During operation, the suspension arm is installed on the vehicle using conventional methods.

When the wheel encounters a hard object:

the suspension arm tilts upward through the movable connecting member and connecting plate;

the fixed outer rod is pressed upward;

the telescopic inner rod slides into the fixed outer rod;

the first spring compresses to provide shock absorption.

Simultaneously:

the cleaning mechanism drives the movable brush ring to slide and clean the suspension arm surface; and

the anti-collision mechanism enables the U-shaped protective plate to compress and absorb impact forces from sharp objects.

The detachable protective plate also facilitates convenient replacement and maintenance.

Conclusion

The utility model integrates:

shock absorption,

automatic cleaning, and

anti-collision protection

into a single suspension structure, thereby improving ride comfort, cleanliness, durability, and protection performance of the suspension arm.
