Independent suspension structure of electric golf cart

Abstract

The utility model relates to the technical field of golf carts, in particular to an independent suspension structure of an electric golf cart, which comprises a steel frame main body, and fixing blocks are symmetrically mounted on two side walls in the steel frame main body. When a car shakes front and back due to the fact that the car encounters an uneven road surface in the car driving process, an arc-shaped block extrudes a sliding block to slide in a groove through a connecting rod, sliding of the sliding block drives a first damper to work, shaking energy is absorbed and slowed down, accordingly, car body shaking is reduced, and the driving stability is improved; when vertical vibration borne by the wheels is transmitted to the second dampers on the fixing plates through the steel frame body, the second dampers absorb vibration energy, the tops of the supporting rods are attached to the rubber blocks on the tops of the inner sides of the fixing frames, the rubber blocks provide additional buffering and buffering effects through the elasticity and abrasion resistance of the rubber blocks, meanwhile, noise is reduced, and the service life of the wheels is prolonged. And the riding comfort is improved.

[0021] The application relates to an independent suspension structure of an electric golf cart, which refers to Figure 4 The inner top and bottom of the recess 201 are provided with limiting grooves 202, the top and bottom of the sliding block 4 are provided with limiting blocks 15 arranged in the limiting grooves 202, and the inner side walls of the limiting grooves 202 and the outer part of the limiting blocks 15 are in sliding connection, so that the limiting blocks 15 slide in the limiting grooves 202, thereby limiting the movement track of the sliding block 4 and improving the stability and reliability of the suspension system.

[0022] The application relates to an independent suspension structure of an electric golf cart, which refers to Figure 1 - Figure 3 One end of the connecting rod 5 and the outer side of the sliding block 4 are in rotary connection, and the end of the connecting rod 5 away from the sliding block 4 and the outer part of the arc-shaped block 6 are in rotary connection, when the car cabin 7 shakes forward and backward, the arc-shaped block 6 will extrude the two groups of connecting rods 5, so that the sliding block 4 in the recess 201 is extruded by the connecting rod 5 to slide, and the first damper 3 is extruded, thereby playing a buffering role through the first damper 3 to reduce the shaking of the car body, the bottom of the arc-shaped block 6 is provided with a support block 16, the bottom of the support block 16 is in close contact with the inner bottom of the steel frame body 1, and the support block 16 slides along the inner bottom of the steel frame body 1 synchronously when the car cabin 7 shakes, thereby preventing the arc-shaped block 6 and the car cabin 7 from being pressed too much downward, so as to protect the overall structure of the suspension system and the vehicle.

[0023] The application relates to an independent suspension structure of an electric golf cart, which refers to Figure 2The top end of the support rod 11 passes through the support plate 12 and extends into the interior of the fixed frame 13. The outer ring surface of the support rod 11 is slidably connected to the interior of the support plate 12. When the support rod 11 is vibrated by the wheel 8, it can move up and down while maintaining close contact with the support plate 12 to ensure the maximum buffering effect. Furthermore, by setting two sets of second dampers 10, the vertical swaying is buffered.

[0024] Reference Figure 1 - Figure 2 A rubber block 17 is installed on the top inner side of the fixed frame 13. The top of the support rod 11 fits against the bottom of the rubber block 17. The rubber block 17 has good elasticity and wear resistance, which can provide additional cushioning effect when the support rod 11 moves up and down, while reducing noise and improving riding comfort.

[0025] The implementation principle of the independent suspension structure of an electric golf cart according to this application embodiment is as follows: During the use of the independent suspension structure of the electric golf cart, when the vehicle encounters an uneven road surface during driving, causing the car body 7 to sway back and forth, the arc-shaped block 6, through the connecting rod 5, squeezes the slider 4 to slide within the groove 201. The sliding of the slider 4 drives the first damper 3 to work, absorbing and reducing the swaying energy, thereby reducing the body sway and improving driving stability. The limiting blocks 15 at the top and bottom of the slider 4 slide within the limiting groove 202, ensuring that the slider 4 moves along a predetermined trajectory, enhancing the stability and reliability of the suspension system. The support block 16 at the bottom of the arc-shaped block 6 is connected to the steel frame body 1. The inner bottom surfaces fit together, and the support block 16 slides synchronously when the car body 7 shakes, preventing the arc block 6 and the car body 7 from being excessively pressed down, protecting the suspension system and the overall vehicle structure from damage. When the wheel 8 is subjected to vertical vibration, it is transmitted through the steel frame body 1 to the second damper 10 on the fixed plate 9. The second damper 10 absorbs the vibration energy. At the same time, the support rod 11 slides inside the support plate 12, maintaining close contact with the support plate 12 to ensure maximum cushioning effect. The top of the support rod 11 fits against the rubber block 17 on the inner top of the fixed frame 13. The rubber block 17 uses its elasticity and wear resistance to provide additional cushioning and buffering effect, while reducing noise generation and improving ride comfort.
