[0042] like Figures 1 to 9 As shown, this embodiment provides an electric vehicle steering mechanism, which includes: a rotating device and a reinforcement member 4. The rotating device includes a handlebar 1, a pressure block assembly 2, a head tube 3, and a steering column assembly. The handlebar 1 is mounted on the pressure block assembly 2, which is connected to the steering column assembly. The steering column assembly is rotatably connected to the head tube 3. The rotating device is made of a low-density composite material, and the reinforcement member 4 is connected to the pressure block assembly 2, and the reinforcement member 4 is made of a high-strength material. This arrangement adopts a combined structural design of the reinforcement member 4 and the rotating device, wherein the pressure block assembly 2, as the main structural part of the steering mechanism, is made of a low-density composite material, and the reinforcement member 4, as the reinforcing support part of the steering mechanism, is made of a high-strength material. This takes into account the lightweight design of the steering mechanism while further improving the structural strength.

[0043] Specifically, the reinforcement member 4 is made of Q235A material, and the rotating device is made of ADC6 material. Of course, in other embodiments, the materials of the reinforcement member 4 and the rotating device can also be set according to actual needs, and no further limitation is made here.

[0044] Specifically, this embodiment exemplifies the following solution: the pressure block assembly 2 includes an upper pressure block 21 and a lower pressure block 22. The upper pressure block 21 is recessed with a first groove, and the lower pressure block 22 is recessed with a second groove. The upper pressure block 21 is connected to the lower pressure block 22 so that the first groove and the second groove are spliced to form a mounting slot. The steering handle 1 is embedded in the mounting slot. The lower pressure block 22 is connected to the steering column assembly. The reinforcement member 4 is connected to the lower pressure block 22, and the density of the reinforcement member 4 is greater than that of the lower pressure block 22. With this arrangement, the upper pressure block 21 and the lower pressure block 22 are connected by multiple bolts, and the two can be detachably connected, facilitating the disassembly and assembly of the steering handle 1. At the same time, the reinforcement member 4 is reinforced and connected to the lower pressure block 22, which can further enhance the overall connection strength of the rotating device.

[0045] Alternatively, see Figures 6 to 9 As shown, the steering column assembly includes a vertical tube 5 and an insert 6. The insert 6 is located at one end of the vertical tube 5 and is embedded in the vertical tube 5. The electric vehicle steering mechanism also includes a connector 7. A lower pressure block 22 is sleeved on the vertical tube 5. The connector 7 passes through the lower pressure block 22 and is connected to the insert 6. Furthermore, the connector 7 is a fastening bolt that passes through the lower pressure block 22 and is threadedly connected to the insert 6.

[0046] Optionally, the reinforcement member 4 has an embracing structure and has a first connecting end and a second connecting end located at its two ends. The electric vehicle steering mechanism further includes a first locking member 8 and a second locking member 9. The first locking member 8 is disposed at the first connecting end, passes through the reinforcement member 4, and is connected to the lower pressing block 22. The second locking member 9 is disposed at the second connecting end, passes through the reinforcement member 4, the lower pressing block 22, the standpipe 5, and is connected to the insert 6. Furthermore, the first locking member 8 and the second locking member 9 are both fastening bolts.

[0047] Optionally, to further enhance the position-limiting and restraining effect of the reinforcement member 4, the reinforcement member 4 is provided with a recessed position-limiting slot 41. The electric vehicle steering mechanism further includes a position-limiting member 10, which passes through the position-limiting slot 41 and is connected to the standpipe 5. Furthermore, the position-limiting member 10 is a fastening bolt. It should be noted that the density of the position-limiting member 10 is approximately the same as that of the reinforcement member 4.

[0048] Furthermore, a flange 42 is provided around the periphery of the limiting slot 41, and a limiting groove is defined in the lower pressing block 22, into which the flange 42 engages. This arrangement, coupled with the snap-fit structure of the flange 42, separates the limiting member 10 from the lower pressing block 22, effectively preventing the limiting member 10 from frequent contact and collision with the lower pressing block 22 during actual vehicle operation, thereby further improving the structural strength and extending its service life.

[0049] Optionally, to limit the rotation of the steering column assembly, the steering column assembly further includes a base 11 and a limiting post 12. The base 11 is connected to the other end of the head tube 3, and the limiting post 12 is protruding from the base 11. A baffle 13 is protruding from the outer wall of the head tube 3, and the limiting post 12 can abut against the baffle 13 along the circumferential direction. It should be noted that the location and number of the limiting posts 12 can be designed to limit the angular range of the steering column assembly according to actual needs and are not further specified here.

[0050] Optionally, in order to support the rotation of the steering column assembly, reduce the friction coefficient during its movement, and ensure the rotation accuracy, the electric vehicle steering mechanism also includes a first bearing assembly 14 and a second bearing assembly 15. The first bearing assembly 14 and the second bearing assembly 15 are respectively arranged at both ends of the head tube 3, and the first bearing assembly 14 and the second bearing are both connected between the head tube 3 and the steering column assembly.

[0051] Optionally, the electric vehicle includes a main pipe and a frame, and the main pipe is fixedly connected between the frame and the head pipe 3. Further, the electric vehicle also includes a reinforcing rib, and the reinforcing rib is fixedly connected between the head pipe 3 and the main pipe.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
