Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] As Figure 1 - Figure 2 A specific embodiment of the utility model discloses a staggered folding pole is shown:

[0026] Comprising the following components:

[0027] ‌Pull rod 1: adopt stainless steel material, two ends are connected with pull rod connecting piece 4 and front pole 2 through bolt respectively;

[0028] ‌Front pole 2: aluminum alloy material, the end is welded with U-shaped mounting plate, is fixed through double-side bolt and passes through pull rod connecting piece 4;

[0029] ‌Rear pole 3: be connected with transmission motor (not shown in drawing), the end is equipped with flange plate, is fixed with driving shaft coaxially through bolt;

[0030] ‌Pull rod connecting piece 4: ladder-shaped structure, is divided into fixed connection part 401 and front pole mounting part 402.

[0031] ‌Installation steps:

[0032] The flange plate of rear pole 3 is aligned with the driving shaft of transmission motor, and is fixed by bolt;

[0033] The fixed connection part 401 of pull rod connecting piece 4 is connected with rear pole 3, and the vertical staggered height of ladder-shaped structure is ensured to be 50mm;

[0034] The U-shaped mounting plate 201 of front pole 2 is inserted into the front pole mounting part 402 of pull rod connecting piece 4, and is connected by double-side bolt, and is locked after adjusting front pole 2 to "standard height" position;

[0035] The two ends of pull rod 1 are connected, one end is hinged with pull rod connecting piece 4 through universal joint, and the other end is fixed with the folding end of front pole 2.

[0036] ‌Working principle:

[0037] If the vehicle hits front pole 2, the impact force is transmitted to pull rod connecting piece 4 through U-shaped mounting plate, and due to the staggered height difference (50mm) of front pole 4 and rear pole 3, the impact force is decomposed into vertical and horizontal components, the horizontal component is conducted to rear pole 3 through the tension of pull rod 1, and the vertical component is absorbed by the spring of elastic connecting piece, so that the connection between rear pole 3 and motor is avoided from being deformed.

[0038] On the basis of embodiment 1, the elastic connecting piece (5) and the anti-collision block (203) are added, and the anti-collision performance is further optimized.

[0039] ‌Structural details‌: elastic connecting piece: adopt a coil spring, fixed between the pull rod connecting piece 4 and the rear rod 3 through a detachable buckle;

[0040] ‌Anti-collision block: polyurethane material, thickness of 20mm.

[0041] ‌Working scene: when the vehicle collides with the front rod 2 at low speed (such as 5km / h), the anti-collision block first contacts the vehicle body, and absorbs part of the impact force through deformation; the remaining impact force is transmitted to the elastic connecting piece through the pull rod connecting piece 4, and the spring compression deformation further buffers the energy, so that the device function can be restored by replacing the anti-collision block only, without the need of repairing the rear rod 3 or the motor.

[0042] On the basis of embodiment 1, the reinforcing rib is added:

[0043] The reinforcing rib is added between the front rod mounting portion 402 of the pull rod connecting piece 4 and the rear rod 3;
