[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 2 As shown, the steering column for a handlebar-type four-wheel steering rocker includes a steering column body 4 and a steering block 7. A plurality of sets of fixing plates 3 are provided on the steering column body 4. The top end of the steering column body 4 is connected to a steering shaft 2 through a first steering bearing. The other end of the steering shaft 2 is connected to a fastening nut 1. The bottom end of the steering column body 4 is connected to a first connecting member 5 through a second steering bearing. The steering block 7 is connected to a second connecting member 6. The first connecting member 5 and the second connecting member 6 are connected through a steering connecting rod 9. The steering connecting rod 9 is hinged to the first connecting member 5 and the second connecting member 6.

[0017] The original single steering block 7 structure is changed, and the steering connecting rod 9 and the first connecting member 5 and the second connecting member 6 are combined to form free rotation up and down, thereby offsetting the conductive force and achieving the effect of reducing vibration.

[0018] Furthermore, the first connecting member 5 includes a first U-shaped frame 5.2, a support column 5.1 is provided at the top of the first U-shaped frame 5.2, the support column 5.1 is connected to the steering column body 4 through a second steering bearing, and the opening of the first U-shaped frame 5.2 is rotatably connected to one end of the steering connecting rod 9 through a bolt and nut assembly 11.

[0019] Furthermore, the second connecting member 6 includes a second U-shaped frame, and the opening of the second U-shaped frame is rotatably connected to one end of the steering connecting rod 9 through a bolt and nut assembly 11.

[0020] The first connecting member 5 and the second connecting member 6 both adopt a U-shaped frame structure, and cooperate with the bolt and nut assembly 11, which is easy to assemble and has a stable structure.

[0021] In order to adapt to the additional steering connecting rod 9 and enable the steering block 7 to be better connected to the steering connecting rod 9 , further, the steering block 7 is an L-shaped structure, and a mounting hole 8 is provided at one end of the steering block 7 away from the second connecting member 6 .

[0022] Furthermore, an axial hole 10 is reserved in the middle of the steering connecting rod 9. Different from the existing mechanical rigid connection, the reserved axial hole 10 can be optimized into an axial connection mode to achieve better shock absorption and noise reduction effects.

[0023] In actual use, the steering connecting rod 9 can offset the direct or indirect transmission force of the real-time road conditions by freely rotating the steering connecting rod 9 up and down, thus avoiding the direct transmission of the up and down jumping force of the tires caused by the real-time road conditions to the steering adjustment rod, and indirectly reacting to the steering handlebar through the steering column body 4, causing the steering handlebar to vibrate and affecting the driving comfort of the driver and passengers.

[0024] In addition, the application of this structure changes the rigid interaction force between components, thereby extending the service life of related components and reducing the probability of component damage while meeting the performance and quality of the entire vehicle.
