[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figures 1 to 4 As shown, this embodiment provides a frame assembly for an electric scooter, comprising: a first angle steel 1, a second angle steel 2, a reinforcement member 3, a head tube 4, and a support tube 5. The first angle steel 1 extends in the front-to-back direction, and the second angle steel 2 extends in the front-to-back direction. The first angle steel 1 and the second angle steel 2 are opposite and spaced apart in the left-to-right direction. The reinforcement member 3 is fixedly connected between the first angle steel 1 and the second angle steel 2 and is disposed at the front end of the first angle steel 1. The head tube 4 has a square cross-section, and the support tube 5 has a square cross-section. One end of the support tube 5 is fixedly connected to the side wall of the head tube 4, and the other end of the support tube 5 is fixedly connected to the reinforcement member 3. Furthermore, the reinforcement member 3, the support tube 5, the first angle steel 1, and the second angle steel 2 are integrally formed. In this arrangement, the first angle steel 1 and the second angle steel 2 are used as two side supports of the frame body, which enhances the frame's anti-rollover ability. The head pipe 4 serves as the front end support of the frame body. Compared with the traditional round tube structure, the cross-section of the head pipe 4 is square, and it has four equal right-angled sides. The right-angled sides can better disperse and resist external forces, so that the head pipe 4 has advantages in bearing pressure and bending strength, and has high strength and stability. In addition, a reinforcement 3 is added to the front end stress-bearing part, and the support tube 5, the first angle steel 1 and the second angle steel 2 are connected to form an integral structural assembly, so that the frame has higher stability when bearing heavy loads and impacts, and effectively improves the overall strength and rigidity of the electric scooter frame.

[0038] Optionally, the first angle steel 1 includes two first joining plates, which are vertically connected, and the second angle steel 2 includes two second joining plates, which are vertically connected, one of the first joining plates and one of the second joining plates are parallel to each other, and the other first joining plate and the other of the second joining plates are located on the same horizontal plane.

[0039] It should be noted that the main body of the frame adopts an angle steel structure, and its flat state is conducive to drilling and tapping, thereby improving the qualified rate of one-time frame production. At the same time, the L-shaped cross-section of the angle steel not only provides excellent bending resistance, but also provides a precise matching plane for drilling and tapping. The thread positions on the upper side of the first angle steel 1 and the second angle steel 2 are conducive to the fixation of the front cover, pedals, batteries, controllers, and rear fenders. The thread positions on the left and right sides of the first angle steel 1 and the second angle steel 2 are conducive to the fixation of the front cover and the lower cover.

[0040] Optionally, the reinforcement 3 is a sheet metal component and includes a first reinforcement piece 31 and a second reinforcement piece 32. The first reinforcement piece 31 protrudes from the second reinforcement piece 32. The first reinforcement piece 31 is fixedly connected between the other first joining plate and the other second joining plate, and the second reinforcement piece 32 is fixedly connected between one of the first joining plates and one of the second joining plates. This arrangement effectively increases the number of fixing points between the reinforcement 3 and the first angle steel 1 and the second angle steel 2, further enhancing the load-bearing capacity of the front end of the frame.

[0041] It should be noted that the reinforcement 3 is the only bent part in the frame. The frame assembly structure greatly reduces the number of frame splicing parts, simplifies the bent sheet metal structure, and optimizes the processing technology.

[0042] Optionally, the first reinforcement sheet 31 defines a first mounting hole, and the second reinforcement sheet 32 defines a second mounting hole. The other end of the support tube 5 is sequentially penetrated by the first and second mounting holes, so that the end surface of the other end of the support tube 5 blocks the second mounting hole, and the walls of the first and second mounting holes are fixedly connected to the outer wall of the support tube 5. In this arrangement, the square support tube 5 penetrates the reinforcement member 3 and is welded to the upper and lower layers of the reinforcement member 3, namely, the first reinforcement sheet 31 and the second reinforcement sheet 32. The outer side of the reinforcement member 3 is welded to the first angle steel 1 and the second angle steel 2 to form a monolithic structure, greatly enhancing the overall strength of the vehicle frame.

[0043] It should be noted that the main body of the frame adopts an angle steel structure, so that the welds are mostly in a straight line during welding, thereby simplifying the welding process and reducing manufacturing costs.

[0044] In this embodiment, the electric scooter frame assembly also includes a front reinforcement plate 6 and a rear reinforcement plate 7. The front reinforcement plate 6 is disposed between the first angle steel 1 and the second angle steel 2 and is fixedly connected to the reinforcement member 3, the first angle steel 1, and the second angle steel 2. The rear reinforcement plate 7 is located closer to the rear end of the first angle steel 1 than the front reinforcement plate 6 and is fixedly connected between the first angle steel 1 and the second angle steel 2. Furthermore, both the front reinforcement plate 6 and the rear reinforcement plate 7 are angle steels. With this arrangement, the front reinforcement plate 6 and the rear reinforcement plate 7 are added to the front and rear positions of the frame, respectively. Together with the first angle steel 1 and the second angle steel 2, the front reinforcement plate 6 and the rear reinforcement plate 7 form an H-shaped structure, further enhancing the overall strength and rigidity of the frame.

[0045] Optionally, in order to adapt to the installation of the headset, the frame assembly of the electric scooter further includes a first fixing plate 8 and a second fixing plate 9. The electric scooter includes an upper headset and a lower headset. The first fixing plate 8 is fixedly connected to the top end of the head tube 4, and the first fixing plate 8 is used to install the upper headset. The second fixing plate 9 is fixedly connected to the bottom end of the head tube 4, and the second fixing plate 9 is used to install the lower headset.

[0046] Optionally, the frame assembly of the electric scooter also includes a wire clip 10 and a mounting plate 11, the wire clip 10 is fixedly connected to the first angle steel 1 or the second angle steel 2, and the mounting plate 11 is fixedly connected to the first angle steel 1 or the second angle steel 2. The electric scooter includes a foot support and several wiring harnesses. The wire clip 10 is used to clamp and fix the several wiring harnesses, and the mounting plate 11 is used to fix the foot support.

[0047] Furthermore, the mounting plate 11 is made of Q235 sheet metal material to ensure stability and durability when the kickstand is installed and fixed.
