[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0042] like Figure 1As shown, the frame assembly of the embodiment of the utility model includes a frame body 1 formed by bending a plate, and the plate may specifically be a steel plate, an aluminum plate, etc. During processing, the frame body 1 may be stamped and bent into shape by stamping.

[0043] The frame 1 is a slot-shaped structure having a head end 14 and a tail end 15. The slot-shaped structure extends from the head end 14 to the tail end 15, and the slot of the slot-shaped structure is arranged upward. Figure 2 and Figure 3 As shown, the head end 14 can be the front end of the frame 1, and the head end 14 can be connected and fixed to the head pipe 4 of the frame assembly, and the tail end 15 can be the rear end of the frame 1, and the tail end 15 can be equipped with the rear wheel of the scooter.

[0044] like Figure 4 As shown, along the direction from front to back, any cross section of the frame 1 can be U-shaped, so that the frame 1 as a whole forms a groove structure, that is, the frame 1 as a whole can be channel-shaped, and a groove is formed in the frame 1, and the notch of the groove is arranged upward, and components such as batteries and electronic controllers can be installed in the groove of the frame 1, and the frame 1 can play a certain protective role.

[0045] At least one edge of the notch of the groove-like structure is provided with a flange 16, and the extending direction of the flange 16 is consistent with the extending direction of the groove-like structure. Figures 1 to 3 As shown, the notch of the groove-like structure is located on the top side of the frame 1, and a flange 16 can be provided at the edge of the notch on the left and right sides of the frame 1. The flanges 16 on the left and right sides of the frame 1 can be roughly arranged symmetrically, and the flanges 16 on the left and right sides can extend in the direction from front to back.

[0046] Since the frame 1 is formed by bending the plate, the frame 1 as a whole is a component. Compared with the prior art method of welding plates, steel pipes, etc., it avoids low welding efficiency and complicated welding process, improves processing efficiency, reduces processing costs, and ensures processing accuracy and quality consistency.

[0047] Secondly, the provision of the flange 16 can improve the torsional rigidity and strength of the frame 1, avoiding the situation of easy twisting and deformation, thereby fully ensuring the structural safety during use.

[0048] In some embodiments, the flange 16 is folded and integrally formed with the frame 1. For example, the flange 16 can also be formed by stamping, thereby facilitating the molding and arrangement of the flange 16.

[0049] In some embodiments, Figures 1 to 5 As shown, the flange 16 may be an inner flange folded toward the inner side of the groove-shaped structure, and the groove-shaped structure may be provided with inner flanges at the notches on both sides. Figure 6 and Figure 7 As shown, the flange 16 can also be an outer flange folded toward the outside of the groove structure, and in this case, the groove openings on the left and right sides of the groove structure can also be provided with outer flanges, thereby fully ensuring the consistency and structural strength of the left and right side structures.

[0050] It should be noted that if Figure 4 and Figure 7 As shown, no matter whether the flange 16 is an inner flange or an outer flange, the flange 16 can be generally arranged horizontally, so as to provide convenience for the installation of components such as the upper cover plate 6.

[0051] In some embodiments, the frame 1 includes an integrally formed inclined section 11, a middle section 12 and a tail section 13, the inclined section 11, the middle section 12, and the tail section 13 are sequentially connected along a direction from a head end 14 to a tail end 15, and a flange 16 is provided on at least one of the inclined section 11, the middle section 12, and the tail section 13.

[0052] For example, Figure 3 As shown, along the direction from front to back, the frame body 1 can be divided into an inclined section 11, a middle section 12 and a tail section 13, wherein the inclined section 11 can be integrally formed and connected to the front side of the middle section 12, and the tail section 13 can be integrally formed and connected to the rear side of the middle section 12. The inclined section 11, the middle section 12 and the tail section 13 can all be processed and formed by sheet metal stamping. The inclined section 11 can be processed by stretching and bending.

[0053] like Figure 2 and Figure 3 As shown, the flange 16 may be provided only on the middle section 12 and the tail section 13 of the frame 1, and the flanges 16 of the middle section 12 and the tail section 13 are connected as one. Figure 5 and Figure 6 As shown, the flange 16 can also be arranged on the inclined section 11, the middle section 12 and the tail section 13 at the same time, that is, the flange 16 is distributed throughout the frame 1 from front to back, thereby fully ensuring the torsional rigidity and strength of each position of the frame 1 in the extension direction.

[0054] In some embodiments, the middle section 12 extends in the horizontal direction, the inclined section 11 is arranged upwardly and inclinedly along the direction from the middle section 12 to the head end 14, the middle section 12 and the inclined section 11 are arranged crosswise, and the extension direction of the tail section 13 is consistent with the extension direction of the middle section 12. Figure 3 As shown, the inclined section 11 is generally arranged obliquely along the direction from the upper front to the lower rear, the middle section 12 and the tail section 13 can be arranged horizontally, the front end of the middle section 12 can be integrally connected to the bottom end (rear end) of the inclined section 11, and the rear end of the middle section 12 can be integrally connected to the front end of the tail section 13.

[0055] When in use, the middle section 12 and the tail section 13 can be stepped on by people, so that the inclination angles of the middle section 12 and the tail section 13 are consistent with the design of human standing. The inclined design of the inclined section 11 provides convenience for installing the T-bar assembly and the front wheel assembly of the scooter on the one hand, and can also enhance the overall structural strength on the other hand.

[0056] In some embodiments, the frame assembly includes a first fixing member 2, the first fixing member 2 is fixed to the inclined section 11, and the first fixing member 2 is covered at the notch of the groove structure of the inclined section 11. Figure 1 and Figure 2 As shown, the first fixing member 2 can be a plate-shaped structure, and the first fixing member 2 can also be formed by stamping a plate, and the first fixing member 2 can be fixed to the top side of the inclined section 11 by welding. The provision of the first fixing member 2 can further enhance the structural strength and torsional rigidity of the frame 1, and fully ensure the structural stability during riding.

[0057] In some embodiments, the frame assembly includes a second fixing member 3, and the second fixing member 3 is fixed to one end of the middle section 12 close to the tail section 13 or the tail section 13. For example, the second fixing member 3 can be fixed to the connection between the middle section 12 and the tail section 13, and the second fixing member 3 is located in the groove structure. The first fixing member 2 and the second fixing member 3 can both be fixing plates, for example, Figure 1 and Figure 2 As shown, the second fixing member 3 may also be a plate-shaped structure, and the second fixing member 3 may also be formed by stamping a plate. Specifically, the second fixing member 3 is L-shaped as a whole.

[0058] The second fixing member 3 can also be fixed at the transition position between the middle section 12 and the tail section 13 by welding, and the second fixing member 3 is located in the groove of the frame body 1. The second fixing member 3 can be below the flanges 16 on the left and right sides of the frame body 1, and the top side of the second fixing member 3 can be welded and fixed to the flanges 16 on the left and right sides of the frame body 1, thereby further improving the structural strength and stability of the structure.

[0059] In addition, the second fixing member 3 can also play the role of dividing the groove space in the frame body 1. Since the tail section 13 is used to install the rear wheel, during riding, the dust, mud and water raised by the rear wheel can be blocked by the second fixing member 3, avoiding entering the interior of the frame body 1, thereby playing an isolation and protection role.

[0060] In some embodiments, the first fixing member 2 and the second fixing member 3 are arranged across the upper edge of the slot of the slot-shaped structure covering the frame 1. Figure 1As shown, the first fixing member 2 and the second fixing member 3 both have a certain width in the left-right direction. When assembled, the left side of the first fixing member 2 can be connected to the left side wall of the groove structure, and the right side of the first fixing member 2 can be connected to the right side wall of the groove structure. Similarly, the left side of the second fixing member 3 can be connected to the left side wall of the groove structure, and the right side of the second fixing member 3 can be connected to the right side wall of the groove structure. This can enhance the integrity of the structural connection and improve the overall structural strength.

[0061] In some embodiments, the vehicle frame, the first fixing member and the second fixing member are all made of metal materials, specifically high-strength steel, aluminum alloy, etc.

[0062] In some embodiments, two oppositely arranged side walls of the groove structure of the tail section 13 are provided with mounting holes 131 for mounting the rear wheels. Figure 2 As shown, a mounting hole 131 may be provided on the left and right walls of the tail section 13, and the two mounting holes 131 may be arranged opposite to each other in the left and right directions, and the axles of the rear wheels may be assembled in the two mounting holes 131. This facilitates the installation and arrangement of the rear wheels of the scooter.

[0063] In some embodiments, the bottom wall of the groove-shaped structure of the rear end 15 is provided with an avoidance groove 132, and the avoidance groove 132 is used to avoid and allow the rear wheel to fit in. Figure 2 As shown, the avoidance groove 132 can be a U-shaped groove, and the notch of the avoidance groove 132 can be arranged rearward. When the rear wheel is assembled, a part of the rear wheel can be embedded in the avoidance groove 132, thereby avoiding the problem of installation interference.

[0064] In some embodiments, the frame assembly includes a head tube 4, which is fixed to the head end 14 of the frame body 1. Figure 8 As shown, the head pipe 4 can be in the shape of a round tube, and the head pipe 4 can be welded and fixed to the front end of the frame 1. When assembling the scooter, the head pipe 4 can be used to install a T-bar assembly and a front wheel assembly.

[0065] In some embodiments, the frame 1 of the vehicle frame assembly may be simultaneously mounted with the first fixing member 2 and the second fixing member 3, and the specifications of the plates processed by the frame 1, the first fixing member 2, and the second fixing member 3 are the same. Therefore, the frame 1, the first fixing member 2, and the second fixing member 3 may be processed and formed by plates of the same specifications, specifically, by thin-walled high-strength steel plates of the same specifications. By adopting a unified steel plate specification, the cost of raw materials can be reduced, and the convenience of processing can be further improved.
