The riser pipe is detachably arranged on the connecting rod through the first fastener, the first hole and the second hole.

[0014] The riser pipe is detachably arranged on the connecting rod through the first fastener, the first hole and the second hole, which has the advantages of simple structure and convenient assembly; the detachable connection between the riser pipe and the connecting rod facilitates the modular installation and production of the connecting rod and the riser pipe.

[0015] Preferably, in the steering system structure of an electric vehicle described above, assembly blocks corresponding to the square columns are arranged on the head tube. Assembly holes are formed on the assembly blocks, third holes are formed on the square columns, and it further includes a second fastener. The second fastener passes through the third hole and is tightened in the assembly hole.

[0016] The assembly blocks prevent the square columns from being directly fixed on the outer surface of the head tube, avoiding drilling holes in the head tube and extending the service life of the head tube; the detachable connection between the square columns and the head tube through the second fastener, the third hole and the assembly hole has the advantages of simple structure, convenient assembly and reliable installation.

The head tube 2 is sleeved on the connecting rod 3, and the end of the connecting rod 3 passes through the head tube 2. The riser 4 is sleeved on the connecting rod 3 and connected to the connecting rod 3. The handlebar 1 drives the riser 4 and the connecting rod 3 to rotate. An installation bracket 5 extending in the height direction is provided on the head tube 2, and the installation bracket 5 is used for installing an instrument.

[0024] Preferably, the installation bracket 5 includes a square column 51, a reinforcing plate 52 and an installation plate 53. The number of the square columns 51 is at least two. One end of the square column 51 is spaced at the lower end of the installation plate 53, and the other end of the square column 51 is provided on the head tube 2. Both ends of the reinforcing plate 52 are respectively provided on adjacent square columns 51.

[0025] Preferably, a fixing rod 6 and a fixing block 7 are provided on the installation plate 53, and fixing holes 8 are provided on both the fixing block 7 and the fixing rod 6.

[0026] Preferably, an arc-shaped groove 521 is provided on the reinforcing plate 52. One side of the riser 4 is inserted into the arc-shaped groove 521, and the riser 4 is in contact with the inner side wall of the arc-shaped groove 521.

[0027] Preferably, a first fastener 9 is further included. A first hole 41 is provided on the riser 4, a second hole 31 for aligning with the first hole 41 is provided on the connecting rod 3. The first fastener 9 passes through the first hole 41 and is screwed into the second hole 31. The riser 4 is detachably provided on the connecting rod 3 through the first fastener 9, the first hole 41 and the second hole 31.

[0028] Preferably, assembly blocks 21 corresponding to the square columns 51 one by one are provided on the head tube 2. Assembly holes 211 are provided on the assembly blocks 21, third holes 511 are provided on the square columns 51, and a second fastener 91 is further included. The second fastener 91 passes through the third hole 511 and is screwed into the assembly hole 211.

[0029] Specifically, as shown in Figure 1As shown, the riser 4 extends in the height direction, and the upper end of the riser 4 is assembled in the middle of the handlebar 1. In the embodiment of the present application, the number of square columns 51 is two, and both ends of the reinforcement plate 52 are respectively fixed on the square columns 51 by screws. A passing gap is formed between the square columns 51, the reinforcement plate 52 and the lower surface of the mounting plate 53. The number of the square columns 51 and the reinforcement plate 52 can be increased or decreased according to actual situations.

[0030] When assembling the structure of the electric vehicle steering system, first, the lower end of the riser 4 is sleeved on the connecting rod 3 so that the first hole 41 is aligned with the second hole 31.
