[0005] In order to facilitate the connection between the steering knuckle arm and the front fender bracket, the steering knuckle arm is a gravity cast aluminum part, the mounting platform is provided with a threaded hole, and the bending platform is provided with a mounting hole at a position corresponding to the threaded hole.

[0006] The mounting hole is formed by blanking and stamping.

[0007] In order to increase the strength and rigidity of the plastic part, a flange is provided on one side of the front fender slot.

[0008] In order to ensure the stability of the structural connection, the lower part of the steering knuckle arm and the lower part of the front fender are connected by screws.

[0009] Beneficial effects: The present invention connects the front fender, the front fender bracket assembly, and the steering knuckle arm together through screws. The front fender bracket assembly is first connected to the steering knuckle arm, and then the front fender is connected to the front fender bracket assembly and the steering knuckle arm, which is convenient and easy to install, improves assembly efficiency, and is reliable to install; the front fender bracket assembly mainly adopts blanking and molding processes, and the product has low complexity, simple development, high precision, and good product consistency; the front fender adopts injection molding technology, which can effectively ensure the size of the installation point; the steering knuckle arm is a gravity cast aluminum part with good strength and rigidity performance. The front fender and the front fender bracket assembly are connected together by screws, with good integrity, convenient and simple installation and disassembly, and good vibration performance; at the same time, the screws are avoided from being exposed, and the appearance is beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the split structure of the present invention;

[0011] Figure 2 It is a schematic diagram of the structure of the present invention assembled together. DETAILED DESCRIPTION

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] like Figure 1-2As shown, the front fender device of the scooter includes a steering knuckle arm 1, a front fender bracket 2 and a front fender 3, wherein the front fender 3 is in front of the front fender bracket 2, and the front fender bracket 2 is in front and above the steering knuckle arm 1; the front fender 3 and the steering knuckle arm 1 are connected together through the front fender bracket 2. A mounting platform is provided on one side of the steering knuckle arm 1. The mounting platforms include two left and right platforms. M6 threaded holes 101 are provided on the left and right mounting platforms respectively. The steering knuckle arm 1 is a gravity cast aluminum part. The upper part of the front fender bracket assembly 2 is formed by bending 90° to form a horizontal bending platform. A first mounting hole 201 corresponding to the threaded hole of the mounting platform is provided on the bending platform. The first mounting hole 201 is formed by blanking and stamping. The M6 ​​screw 4 connects the front fender bracket 2 to the steering knuckle arm 1 through the threaded hole 101; the front fender is provided with a slot adapted to the bending platform of the front fender bracket, and a countersunk hole 301 is provided at a position corresponding to the mounting hole on the outer side of the front fender slot, both of which are formed by injection molding; the front fender bracket 2 is a stamping blanking part, a second mounting hole 202 is opened on the vertical surface of the front fender bracket, an M5 projection welding nut 203 is welded at the rear of the second mounting hole 202, and the front fender bracket 2 and the front fender 1 are connected together by an M5 step screw 5; an M5 threaded hole 102 is arranged at the lower part of the steering knuckle arm 1, and the screw 5 is driven into the threaded hole 102 through the countersunk hole 301 at the lower part of the front fender to connect the front fender 3 and the steering knuckle arm 1 together, and the front part of the front fender mounting bracket assembly 2 is bent to form a platform 204 that cooperates with the front fender, and cooperates with the front fender to play a supporting role, and a flange 302 is arranged on one side of the front fender slot to increase the strength and rigidity of the plastic part.
