[0020] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, an anti-rollover device for an electric three-wheel motorcycle includes a support frame 1. A fixed bracket 2 is connected to the bottom of the front end of the support frame 1. Driving wheels 3 are connected to both sides of the fixed bracket 2 through support components. Two groups of fixed slide rails are symmetrically installed inside the support frame 1. Two groups of symmetric moving parts are slidably installed on the fixed slide rails. A shock absorption component is installed between each group of moving parts and the support frame 1. The bottom of the moving part near the front end of the support frame 1 is connected to the top of the support component. A connecting piece is installed on the support frame 1 through a support bridge 4, and the connecting piece controls the simultaneous movement of the moving parts that cross each other in pairs.

[0021] During use, a cart body is assembled on the top of the support frame 1. The support frame 1 and the fixed bracket 2 are assembled with the front end of the electric three-wheel motorcycle. Both of the two rear wheels can be driven independently. During the driving process of the electric three-wheel motorcycle, when the driving wheels 3 are jolted, the driving wheels 3 can drive the support components to move. The support components drive the moving parts connected to their tops to slide on the surface of the fixed slide rails. The moving parts drive the shock absorption components to expand and contract. The above-mentioned moving parts drive the moving parts opposite to them and the shock absorption components to operate together through the connecting piece, which can effectively improve the shock absorption and buffering effect on the driving wheels 3.

[0022] In one embodiment, specifically, the support component includes a first connecting rod 5 rotatably connected to the side surface of the fixed bracket 2. The end of the first connecting rod 5 is fixedly installed with a driving wheel 3. Support blocks 6 are installed on both sides of the first connecting rod 5. The two support blocks 6 and the moving part are connected through a second connecting rod 7. The first connecting rod 5 and the second connecting rod 7 can provide a stable moving support structure for the driving wheel 3.

[0023] Specifically, the fixed slide rails include two groups of round rods 8 arranged in parallel inside the support frame 1, which can provide a stable sliding track for the moving parts. The ends of the round rods 8 are welded to the support frame 1. The shock absorption components are fixedly installed between the two groups of round rods 8.

[0024] The moving member includes a movable block 9 connected to the shock-absorbing component. The bottom of the two groups of movable blocks 9 is connected to the top end of the second connecting rod 7. Sliders 10 that can slide on the surface of the round rod 8 are integrally formed on both sides of the movable block 9. A push rod 11 that is slidably connected to the connecting member is fixedly installed on the top of the movable block 9. The push rod 11 can be welded to the movable block 9. Among them, the support blocks 6 located on both sides of the first connecting rod 5 are detachably connected to it through fixing bolts.

The top end of the second connecting rod 7 is hinged to the bottom of the movable block 9, which facilitates the assembly between components.

[0025] On the basis of the above embodiment, specifically, the connecting member includes a support column 12 fixedly installed at the center of the support bridge 4. Two groups of rotating rods 13 are rotatably installed on the surface of the support column 12. The inside of each group of rotating rods 13 is slidably connected to the push rods 11 at the top of two groups of the movable blocks 9 that cross-correspond to each other. A chute 14 for the movement of the push rod 11 is provided inside the rotating rod 13.

[0026] When the movable block 9 connected to the bottom end of the second connecting rod 7 is pushed, the movable block 9 drives the slider 10 and the push rod 11 to move. The sliding of the push rod 11 inside the rotating rod 13 can realize the rotation of the rotating rod 13. The rotating rod 13 can drive the other group of movable block 9 and push rod 11 opposite to the above-mentioned movable block 9 and push rod 11 to move. The two groups of movable blocks 9 connected by the rotating rod 13 drive the shock-absorbing component to expand and contract at the same time.

[0027] Specifically, the shock-absorbing component includes a shock absorber 15 fixedly connected to the movable block 9 and the support frame 1. A shock-absorbing spring 16 sleeved on the outer circle of the shock absorber 15 is installed between the movable block 9 and the support frame 1. The expansion and contraction of the shock absorber 15 and the shock-absorbing spring 16 can provide an efficient shock-absorbing and buffering effect for the device.
