[0028] Referring to Figs. 1-4 The scooter hand brake structure of one exemplary embodiment of the present disclosure includes a wheel hub motor wheel set 1, a brake assembly 2, and a mounting seat 3. The brake assembly 2 includes a hand brake cable 21, a disc brake clamp 22, and a disc brake disc 23. The disc brake disc 23 is arranged on the wheel hub motor wheel set 1 and rotates synchronously with the wheel hub motor wheel set 1. The disc brake clamp 22 is clamped on the disc brake disc 23. The hand brake cable 21 is used to control the disc brake clamp 22 to clamp the disc brake disc 23. The mounting seat 3 includes a mounting body 31 connected to the vehicle frame 4 of the scooter and a mounting bracket 32 used to fix the disc brake clamp 22. The wheel hub motor wheel set 1 is mounted on the mounting body 31. The mounting bracket 32 is arc-shaped in whole to avoid the disc brake clamp 22.

[0029] In the embodiment, the scooter hand brake structure is suitable for a scooter, mainly aiming at the situation that the electromagnetic brake is not sensitive, power failure and the like, and providing a manual braking scheme to increase safety protection. In assembly, the mounting seat 3 is fixed on the rear axle welding piece 41 of the scooter frame 4, the disc brake disc 23 is assembled with the hub motor wheel set 1 into an integrated body, then the hub motor wheel set 1 is mounted on the mounting body 31 of the mounting seat 3, finally the disc brake clamp 22 is clamped on the disc brake disc 23 and fixedly mounted on the mounting bracket 32 of the mounting seat 3, and the assembly is completed. Since the disc brake clamp 22 is clamped on both sides of the disc brake disc 23, by pulling the hand brake pull wire 21 to drive the piston inside the disc brake clamp 22 to move, the disc brake clamps 22 on both sides of the disc brake disc 23 are simultaneously clamped to lock the disc brake disc 23, so as to lock the rotation of the hub motor wheel set 1, and the braking purpose is achieved. It can be understood that the scooter hand brake structure usually appears in pairs in the scooter, that is, two scooter hand brake structures are symmetrically arranged, at this time the mounting seat 3 is also designed as a symmetric piece arranged on the left and right sides, and the mounting seats 3 arranged on the left and right sides are of the same structure, and the two mounting seats 3 can be used on a single side or simultaneously used. In summary, since the scooter hand brake structure includes the hub motor wheel set 1 and the brake assembly 2, when emergency braking of the scooter is needed, the disc brake clamp 22 is driven to move by pulling the hand brake pull wire 21 to clamp the disc brake disc 23 to generate braking force, so as to lock the rotation of the hub motor wheel set 1; at the same time, the mounting seat 3 in the disclosure is specially used on the scooter to connect the scooter frame 4, the disc brake clamp 22 and the hub motor wheel set 1, and the arc-shaped mounting bracket 32 on the mounting seat 3 leaves a containing space for avoiding the disc brake clamp 22, so as to adapt to most types of disc brake clamps 22.

[0030] In an implementable manner, the width of the mounting seat 3 is 34 mm.

[0031] In an implementable manner, the diameter of the disc brake disc 23 is 100 mm.

Therefore, the total width of the mounting seat 3 is designed to be 34 mm, which aims to increase the stability of the hub motor wheel set 1. A larger width can increase the contact area, assembly length and torsional torque capacity of the motor shaft of the hub motor wheel set 1, so that the scooter is more stable during normal driving and is not easy to tilt. It can be understood that under the condition of a certain structure of the mounting seat 3, the specific size thereof can be adaptively designed to adapt to disc brake discs 23 with different diameters, and not only to disc brake discs 23 with a diameter of 100 mm.

[0033] In an embodiment, the mounting body 31 is in the shape of a convex, and the mounting body 31 has a first mounting portion 311, and the first mounting portion 311 is provided with a first fixing hole 3110 for fixing the hub motor wheel set 1.

[0035] Further, in an embodiment, the straight line segment of the D-shaped first fixing hole 3110 is above the arc segment.

[0036] In this embodiment, the first fixing hole 3110 is designed as a D-shaped opening to fix the motor of the hub motor wheel set 1 so that the motor shaft does not rotate. When installing, first install the 100mm disc brake 23 on the hub motor wheel set 1, fix it with disc brake screws 5, connect the installed hub motor wheel set 1 to the first mounting portion 311, and fix it with the anti-loose nut 6.

[0037] In an embodiment, the mounting body 31 has two second mounting portions 312, which are symmetrically arranged with respect to the first mounting portion 311, and the second mounting portion 312 is provided with a second fixing hole 3120. The extension directions of the first fixing hole 3110 and the second fixing hole 3120 satisfy the perpendicular condition. The second mounting portion 312 is fixed to the rear axle welding piece 41 of the scooter frame 4.

[0038] In an embodiment, the mounting bracket 32 is provided with two third fixing holes 320 for fixing the disc brake clamp 22, and the two third fixing holes 320 are respectively located at the two ends of the arc-shaped mounting bracket 32.

[0039] In this embodiment, the mounting bracket 32 is designed as a structure specially used for fixing the disc brake clamp 22, and the hole positions of the two third fixing holes 320 are adapted to the standard mounting conversion seat. The circular arc segment between the two third fixing holes 320 avoids the disc brake clamp 22 to adapt to most types of disc brake clamps 22. The disc brake clamp 22 is fixed to the mounting bracket 32 of the mounting seat 3, and is fixed at the third fixing hole 320 by the clamp screw 7. The disc brake clamp 22 is adjusted so that it does not produce abnormal noise with the 100mm disc brake 23, and can normally rotate before braking. The adjustment and installation are completed.
