[0028] Reference Figure 1-5 This utility model embodiment discloses a novel shock absorption mechanism for a four-wheeled scooter, which includes: a foot pedal 1, a front drive assembly 4 disposed at the front end of the foot pedal 1, and a rear drive assembly 5 disposed at the rear end of the foot pedal 1.

[0029] The front-drive assembly 4 includes a front-drive frame 44. A first mounting groove and a second mounting groove are formed on the outer wall of the front-drive frame 44. A first bow-shaped rod 45 is rotatably mounted on the inner wall of the first mounting groove via a pivot. First shock absorber rods 412 are rotatably mounted on both ends of the first bow-shaped rod 45 via pivots. A first shock absorber spring 46 is fitted onto the outer wall of the first shock absorber rod 412. A first rocker arm connecting rod 414 is rotatably mounted on the other end of the first shock absorber rod 412 via a pivot. A front wheel connecting axle 413 is rotatably mounted on the other end of the first rocker arm connecting rod 414. A front wheel 410 is provided at the wheel connection end of the front wheel connecting axle 413. A first rocker arm 47 is fixedly mounted on the inner wall of the second mounting groove via a pivot. The other end of the first rocker arm 47 is rotatably mounted on the outer wall of the first rocker arm connecting rod 414 via a pivot. A second rocker arm 48 is rotatably mounted on the outer wall of the rear end of the front-drive frame 44 via a pivot. The other end of the second rocker arm 48 is rotatably mounted with a second rocker arm connecting rod 49 via a pivot. The other end of the second rocker arm connecting rod 49 is rotatably mounted on the outer wall of the front wheel connecting axle 413. A first mudguard 411 is provided above the front wheel 410. A rotating rod connecting column 43 is fixedly mounted on the outer wall of the front drive frame 44. A rotating rod 2 is provided on the rotating rod connecting column 43. A steering handle 3 is provided at the top of the rotating rod 2. A connecting arm 42 is fixedly mounted on the outer wall of the rotating rod connecting column 43 and the outer wall of the rear end of the front drive frame 44. A front drive connecting plate 41 is fixedly mounted on the other end of the connecting arm 42. The front drive connecting plate 41 is fixedly mounted on the front end of the foot pedal 1. A connecting block is fixedly mounted on the outer wall of the rotating rod connecting column 43. A connecting rod 415 is rotatably mounted on the outer wall of the connecting block via a pivot. The other end of the connecting rod 415 is rotatably mounted on the front wheel connecting axle 413 via a pivot.

[0030] In this novel shock-absorbing mechanism for a four-wheeled scooter, the operation of the front drive assembly 4 revolves around two core functions: large-scale swaying steering of the front wheel and shock absorption. When the steering handle 3 is operated, the steering action is transmitted to the rotating rod connecting column 43 via the rotating rod 2. The rotating rod connecting column 43 is linked through the front drive frame 44 via structures such as the first rocker arm 47 and the second rocker arm 48. At the same time, the connecting block cooperates with the connecting rod 415 to drive the front wheel connecting shaft 413 to change its angle, thereby realizing the steering of the front wheel 410. This allows the device to adjust its direction of travel as needed. When encountering bumpy roads, the front wheel 410 moves up and down under the force of the ground. At this time, the first shock-absorbing rod 4... The first rocker arm 45 moves along the structure formed by the first bow-shaped rod 45 and the first rocker arm connecting rod 414. At the same time, the first shock absorber spring 46, which is fitted onto the first shock absorber rod 412, compresses or extends with the movement of the wheel, converting the impact of the road surface into the energy of spring deformation and buffering the vibration. Meanwhile, the first rocker arm 47, the second rocker arm 48 and the second rocker arm connecting rod 49 swing in coordination, working with the first shock absorber rod 412 and the first shock absorber spring 46 to maintain the stability of the front wheel movement and effectively attenuate the vibration. The first mud shield 411 prevents mud and water from splashing into the interior of the assembly during the operation of the wheel, protecting the components and ensuring that the front drive assembly 4 works continuously, stably and smoothly in steering, shock absorption and other functions, thus ensuring the driving performance of the equipment.

[0031] The rear drive assembly 5 includes a rear drive frame 51. A second bow-shaped rod 57 is rotatably mounted on the front end of the rear drive frame 51 via a pivot. A second shock absorber rod 58 is rotatably mounted on both ends of the second bow-shaped rod 57 via a pivot. A second shock absorber spring 59 is fitted on the outer wall of the second shock absorber rod 58. A rear vehicle connecting shaft 54 ​​is rotatably mounted on the other end of the second shock absorber rod 58 via a pivot. A third rocker arm 52 is rotatably mounted on the other end of the rear vehicle connecting shaft 54 ​​via a pivot. The other end of the third rocker arm 52 is rotatably mounted on the rear end of the rear drive frame 51 via a pivot. A rear wheel 510 is rotatably mounted on the wheel connecting end of the rear vehicle connecting shaft 54. A second mudguard 511 is provided above the rear wheel 510. L-shaped plates 55 are fixedly mounted on the outer walls of both sides of the middle section of the rear drive frame 51. A rear drive connecting plate 56 is fixedly mounted on the outer wall of the L-shaped plate 55. The rear drive connecting plate 56 is fixedly mounted on the rear end of the foot pedal 1. A baffle 53 is fixedly mounted on the outer wall of the front end of the rear drive frame 51.

[0032] In this novel shock-absorbing mechanism for a four-wheeled scooter, the second bow-shaped rod 57 at the front end of the rear drive frame 51, the second shock-absorbing rod 58 mounted on both ends via a pivot, and the second shock-absorbing spring 59 fitted on the outer wall of the second shock-absorbing rod 58 constitute a shock-absorbing structure. When the scooter is in motion, the rear wheel 510 moves up and down when encountering bumps. The second shock-absorbing rod 58 moves along the second bow-shaped rod 57 and other components, and the second shock-absorbing spring 59 compresses or extends, absorbing road impacts and buffering vibrations. The rear connecting shaft 54 ​​connects the second shock-absorbing rod 58 to the third rocker arm 52. The other end of the third rocker arm 52 is rotatably mounted at the rear end of the rear drive frame 51. The three components swing in tandem, assisting in shock absorption and maintaining rear wheel stability. The L-shaped plates 55 on both sides of the middle of the rear drive frame 51 and the rear drive connecting plate 56 fix the rear drive assembly 5 to the rear end of the foot pedal 1. The second mudguard 511 prevents mud and water from splashing in, protecting the assembly and ensuring the equipment's driving performance.

[0033] Working principle: The front drive assembly 4 drives the front drive frame 44 to turn via the steering knob 3, rotating rod 2, and rotating rod connecting column 43. When driving, the front wheel 410 moves up and down due to bumps. The shock absorption structure composed of the first bow-shaped rod 45, the first shock absorber rod 412, and the first shock absorber spring 46 buffers the impact. The first rocker arm 47 and the first rocker arm connecting rod 414 and other linkage mechanisms assist the wheel movement. The connecting block and connecting rod 415 enhance steering stability. The front drive frame 44 is fixed to the front end of the foot pedal 1 via the connecting arm 42 and the front drive connecting plate 41. When the rear drive assembly 5 is working, the rear wheel 510 is impacted. The second bow-shaped rod 57, the second shock absorber rod 58, and the second shock absorber spring 59 absorb the shock. The rear vehicle connecting axle 54 and the third rocker arm 52 and other structures provide support and guidance. The rear drive frame 51 is fixed to the rear end of the foot pedal 1 via the L-shaped plate 55 and the rear drive connecting plate 56. The baffle 53 provides protection for the rear drive assembly 5.
